| ○ | ○ | Article | Alteration in skeletal posture between breast reconstruction with latissimus dorsi flap and mastectomy: a prospective comparison study | Background: The latissimus dorsi (LD) flap is used in cases of immediate breast reconstruction after total or partial mastectomy. However, studies on the effect of unilateral LD flap reconstruction on skeletal posture and comparison with results from mastectomy-only have been sparse. Thus in this prospective, observational study, we compared skeletal posture and functional recovery in patients who underwent a mastectomy-only versus those who underwent breast reconstruction with a LD flap after mastectomy. Methods: From January 2018 to February 2020, a total of 54 patients were enrolled. The control group included 23 patients who underwent mastectomy-only and the experimental group included 31 patients who underwent breast reconstruction using a LD flap immediately after mastectomy. We assessed the Cobb's angle in spine X-rays, parameters derived from photometry, computed tomography (CT), and 3D scanning preoperatively (T0), 6 months post-surgery (T1), and 1-year post-surgery (T2). We also evaluated functional outcomes, such as pain intensity, disability of the upper extremities, and quality of life. Results: In the control and experimental groups, the average age was 58.7/46.2 years, body mass index (BMI) was 24.9/22.5, and excised mass weight was 386.8/259.1 g, respectively. In the control group, differences in the Cobb's angle were significant between T0 and T2 (P=0.003). There were significant differences in the Cobb's angle and time interaction effects between the two groups (P=0.015). The degree of change in the Cobb's angle between T0 and T1 was positively correlated with change in the vertical distance from the 3D scanner midline to the nipple (P=0.009). Conclusions: The experimental group showed improved recovery in skeletal posture compared to the control group. Further, discovering the parameters that can predict the change of skeletal posture through a 3D scanner will have clinical significance. Accordingly, performing breast reconstruction by unilaterally applying the LD muscle is a safe, reliable, and useful method of autologous tissue transfer for breast cancer patients. | Lee, Joon Seok; Park, Eunhee; Lee, Jung Ho; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug; Jung, Tae-Du | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 130 Dongduk Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, 130 Dongduk Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | Yang, Jung/R-7806-2019; PARK, JUN-YOUNG/P-5981-2015; LEE, JIN/Q-3108-2018; Lee, Jong-Mok/KVY-9550-2024; Lee, Jungho/AAJ-7137-2020 | 56496041000; 56107216400; 57202925792; 37079213100; 56564377200; 55171704700; 36622364500 | lambyang@knu.ac.kr;teeed0522@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 10 | 5 | SCIE | SURGERY | 2021 | 2.16 | 60.3 | 1.82 | 2025-07-30 | 12 | 13 | Mastectomy; mammaplasty; quality of life; surgical flaps | KOREAN VERSION | mammaplasty; Mastectomy; quality of life; surgical flaps | English | 2021 | 2021-05 | 10.21037/gs-21-31 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Comparison of healthcare resource utilization and medical costs between patients with seropositive and seronegative rheumatoid arthritis | Objectives: To compare healthcare utilization and medical costs between patients with seronegative (SN) and seropositive (SP) rheumatoid arthritis (RA). Methods: We conducted a nationwide population study using the Korean health insurance claims database in 2016. We divided patients with RA into SN and SP groups and compared healthcare utilization including medications, medical utilization, and direct medical costs for 1 year between the groups in a cross-sectional analysis. Differences in costs between patients with SPRA and SNRA were assessed using the quantile regression model. We performed longitudinal analysis using data from 2012 and 2016 to examine changes over time. Results: A total of 103,815 SPRA and 75,809 SNRA patients were included in the analyses. The SPRA group used significantly more methotrexate (73.2% versus 30.3%) and biologic agents (7.9% versus 2.9%) than the SNRA group. The number of RA-related outpatient visits [6.0 +/- 3.7 versus 4.4 +/- 4.0 times/year, standardized difference (SD) = 0.41] and annual medical costs per patient ($1027 versus $450/year, SD = 0.25) were higher in the SPRA group than the SNRA group. Quantile regression results indicated that the incremental cost of seropositivity on total medical costs of RA patients gradually increased as medical costs approached the upper quantile. The annual direct medical costs for each patient between 2012 and 2016 increased in both groups: by 25.1% in the SPRA group and 37.6% in the SNRA group. Conclusion: Annual RA-related direct medical costs and RA-related healthcare utilization per patient are higher in patients with SPRA than those with SNRA. | Kim, Hyoungyoung; Cho, Soo-Kyung; Choi, Seongmi; Im, Seul Gi; Jung, Sun-Young; Jang, Eun Jin; Sung, Yoon-Kyoung | Andong Natl Univ, Dept Informat Stat, Andong 36729, Gyeongsangbuk D, South Korea; Hanyang Univ, Dept Rheumatol, Hosp Rheumat Dis, Wangshimni Ro 222-1, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Hlth Insurance Res Inst, Natl Hlth Insurance Serv, Wonju, South Korea; Chung Ang Univ, Coll Pharm, Seoul, South Korea | 57202108695; 35185890800; 57211676692; 57201022006; 57207445502; 37861741600; 15754508900 | jejstat@gmail.com;sungyk@hanyang.ac.kr; | THERAPEUTIC ADVANCES IN MUSCULOSKELETAL DISEASE | THER ADV MUSCULOSKEL | 1759-720X | 1759-7218 | 13 | SCIE | RHEUMATOLOGY | 2021 | 3.625 | 60.3 | 0.59 | 2025-07-30 | 4 | 5 | medical utilization; medication; rheumatoid arthritis; seropositivity | ANTICITRULLINATED PROTEIN ANTIBODY; DISEASE-ACTIVITY; RADIOGRAPHIC PROGRESSION; COHORT; POSITIVITY | medical utilization; medication; rheumatoid arthritis; seropositivity | abatacept; corticosteroid; cyclic citrullinated peptide antibody; etanercept; golimumab; infliximab; interleukin 17; interleukin 6; rituximab; tofacitinib; adult; algorithm; Article; controlled study; cross-sectional study; diagnostic test accuracy study; disease activity; drug cost; female; fibromyalgia; health care; health care cost; health care organization; health care utilization; health insurance; hospitalization; human; interstitial lung disease; interstitial pneumonia; length of stay; major clinical study; male; multicenter study; osteoporosis; outpatient; pelvic organ prolapse; population research; predictive value; prescription; remission; rheumatoid arthritis; synovitis; systemic lupus erythematosus; total knee arthroplasty | English | 2021 | 2021-06 | 10.1177/1759720x211024830 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Delayed unilateral hematoma after reconstructive and aesthetic breast surgery with implants in Asian patients: two case reports | Hematomas represent one of the postoperative complications in patients undergoing reconstructive or aesthetic breast surgery with a silicone implant. Although there are few reports of intracapsular hematoma, those presenting late hematoma after reconstructive and aesthetic augmentation surgeries are rarer. This study reported two Asian patients with late hematoma after reconstruction and aesthetic breast surgery. A 54-year-old female patient underwent bilateral nipple-sparing mastectomy with immediate breast reconstruction using anatomically shaped textured implant for intraductal carcinoma in August 2019. Contralateral nipple-sparing mastectomy was performed for the BRCA gene mutation on the left breast, which was immediately reconstructed with an anatomically shaped textured implant. In a 1-year postoperative magnetic resonance imaging evaluation, an extracapsular hematoma was found on the right side, which was removed following the removal of both implants. Another case was a 63-year-old female patient who underwent augmentation of both breasts with smooth round implants and experienced right unilateral swelling and painless firmness about 30 years postoperatively. A preoperative magnetic resonance imaging evaluation showed both intracapsular and extracapsular ruptures on the right breast and a bulging implant herniation on the left breast. During the operation, hematoma, implants, and capsule were all removed. The excised capsule was sent for histological evaluation. Slightly dark colored blood was emptied before removing the semisolid-state intracapsular hematoma. In both cases, the patients responded well postoperatively and were discharged to their homes with no postsurgical complications, including seroma, or additional hematoma on the breasts. The etiology of late hematoma following breast augmentation or reconstruction has been poorly characterized. Further reports are needed to clearly establish the reasons for this increase in late hematoma formation. | Lee, Jong Ho; Hong, Hyun Ki; Kim, Won Hwa; Kim, Hye Jung; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug; Lee, Joon Seok | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Chilgok Hosp, Sch Med, Dept Radiol, Daegu, South Korea | LEE, JIN/Q-3108-2018; Lee, Jong-Mok/KVY-9550-2024; Yang, Jung/R-7806-2019 | 57212661146; 57210147816; 36081886500; 57203506201; 37079213100; 56564377200; 55171704700; 56496041000 | leejspo@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 10 | 4 | SCIE | SURGERY | 2021 | 2.16 | 60.3 | 0.17 | 2025-07-30 | 1 | 1 | Hematoma; breast implantation; implant capsular contracture; hematoma post breast reconstruction; intracapsular hematoma; extracapsular hematoma | CAPSULAR HEMATOMA; COMPLICATION | breast implantation; extracapsular hematoma; Hematoma; hematoma post breast reconstruction; implant capsular contracture; intracapsular hematoma | English | 2021 | 2021-04 | 10.21037/gs-20-854 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Porcine training models for endoscopic and robotic reconstructive breast surgery: a preliminary study | Background: With recent advances in surgical techniques, minimally invasive methods for reconstructive breast surgery are being investigated. To enhance surgical proficiency through training and minimize predictable complications before human application, we conducted a preliminary experimental study of reconstructive breast surgery using a porcine model. Methods: Between February and March 2019, four 3-month-old pigs underwent a bilateral mastectomy and immediate breast reconstruction with a latissimus dorsi (LD) flap or silicone implants. After performing the mastectomy by dissecting the pectoralis profundus in the subcutaneous plane, the pig was placed in the decubitus position, and ultrasound-guided marking was used to design the LD flap. The thoracodorsal artery was marked, and a 4-cm incision was made on the midaxillary line. An additional endoscopic incision was made in the inferior margin of the LD flap; a 2-hole approach was used for endoscopic LD flap elevation. In the silicone implant model, a silicone implant (Allergan, smooth, round type, 90 cc) was placed using a single incision (4-5 cm). Results: Eight mastectomies followed by breast reconstruction with LD flap elevation or silicone implant models were performed on four pigs. Serious complications, such as active bleeding, did not occur. However, heat dispersion to the skin flap that became thinner by endoscopic dissection caused a second-degree burn in one pig. Conclusions: This preliminary study of endoscopic or robot-assisted minimally invasive reconstructive breast surgery demonstrates that a porcine training model is a highly valuable experimental model for surface anatomy verification, incision plan selection, instrument selection, operator proficiency enhancement, and complication prevention. | Lee, Joon Seok; Lee, Jeeyeon; Kim, Yun Hyun; Park, Ho Yong; Yang, Jung Dug | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 130 Dongduk Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, 807 Hoguk Ro, Daegu 41944, South Korea | LEE, JIN/Q-3108-2018; Yang, Jung/R-7806-2019; PARK, JUN-YOUNG/P-5981-2015; Lee, Jong-Mok/KVY-9550-2024 | 56496041000; 37079213100; 57212668506; 56564377200; 55171704700 | phy123@knu.ac.kr;lambyang@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 10 | 8 | SCIE | SURGERY | 2021 | 2.16 | 60.3 | 0.33 | 2025-07-30 | 3 | 2 | Reconstructive breast surgery; porcine training model; endoscopic and robotic surgery | MUSCLE; PIG | endoscopic and robotic surgery; porcine training model; Reconstructive breast surgery | English | 2021 | 2021-08 | 10.21037/gs-21-398 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Simultaneous nipple reconstruction in autologous breast reconstruction | Background: Reconstruction of the nipple-areola complex is the final step in surgical restoration of the breast. Nipple-areola reconstruction was previously done after an interval of several months using variable techniques, often resulting in low projection and flattened breast mound over time. We present algorithm of simultaneous nipple reconstruction (SNR) that leaves adequate residual projection and naturally shaped breast mound. Methods: Forty patients underwent a skin-sparing mastectomy and nipple excision between October 2016 and December 2020. In the control group, 21 patients underwent delayed nipple reconstruction for 6 months after breast reconstruction. The experimental group of 19 patients underwent nipple and breast reconstruction simultaneously. We collected relevant information and photographs of nipple profiles of both groups in the preoperative, postoperative 6-month, and postoperative 1-year time periods. We also examined the ratio between the reconstructed and contralateral nipples. Results: Scores regarding patient satisfaction questionnaire averaged higher in experimental groups to every category. The control group's scores gradually declined over time and the experimental group showed lesser decline. At the 1-year postoperative follow-up, the mean projection of the immediately reconstructed nipple was approximately the same as the contralateral nipple at 91%, whereas the delayed reconstructed nipple resulted in a 77% ratio. Conclusions: Nipple reconstruction should no longer be considered as a secondary complement to immediate breast reconstruction. The nipple appears to be essential component of breast reconstruction for patient. SNR with immediate breast reconstruction is a simple and reliable technique, giving stable aesthetic results over time. | Lee, Jong Ho; Ryu, Jeong Yeop; Lee, Jung Ho; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug; Lee, Joon Seok | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | Lee, Jong-Mok/KVY-9550-2024; Yang, Jung/R-7806-2019; PARK, JUN-YOUNG/P-5981-2015; LEE, JIN/Q-3108-2018; Lee, Keon Jae/C-1722-2011; Lee, Jungho/AAJ-7137-2020; Ryu, Jeong Yeop/GLQ-9419-2022 | 57212661146; 56366349400; 57202925792; 37079213100; 56564377200; 55171704700; 56496041000 | leejspo@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 10 | 10 | SCIE | SURGERY | 2021 | 2.16 | 60.3 | 0.5 | 2025-07-30 | 5 | 6 | Simultaneous nipple reconstruction (SNR); one-stage nipple; breast reconstruction | AREOLA COMPLEX RECONSTRUCTION; SPARING MASTECTOMY; FLAP; IMMEDIATE; PROJECTION; CARTILAGE | breast reconstruction; one-stage nipple; Simultaneous nipple reconstruction (SNR) | English | 2021 | 2021-10 | 10.21037/gs-21-338 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | A Performance Evaluation of Potential Intensity over the Tropical Cyclone Passage to South Korea Simulated by CMIP5 and CMIP6 Models | Potential intensity (PI) is a metric for climate model evaluation of TC-related thermodynamic conditions. However, PI is utilized usually for assessing basin-wide TC-related thermodynamic conditions, and not for evaluating TC passage to a certain region. Here we evaluate model-simulated PI over the passage of TCs affecting South Korea (KOR PI) as well as the PI over the entire western North Pacific basin (WNP PI) using 25 CMIP5 and 27 CMIP6 models. In terms of pattern correlations and bias-removed root mean square errors, CMIP6 model performances for KOR PI are found to be noticeably improved over CMIP5 models in contrast to negligible improvement for WNP PI, although it is not in terms of normalized standard deviations. This implies that thermodynamic condition on the route of TCs affecting South Korea is likely better captured by CMIP6 models than CMIP5 models. | Park, Doo-Sun R.; Kim, Hyeong-Seog; Kwon, Minho; Byun, Young-Hwa; Kim, Maeng-Ki; Chung, Il-Ung; Park, Jeong-Soo; Min, Seung-Ki | Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Korea Maritime & Ocean Univ, Ocean Sci & Technol Sch, Busan 49112, South Korea; Korea Inst Ocean Sci & Technol, Ocean Circulat & Climate Res Ctr, Busan 49111, South Korea; Natl Inst Meteorol Sci, Climate Res Div, Jeju 63568, South Korea; Kongju Natl Univ, Dept Atmospher Sci, Gongju 32588, South Korea; Gangneung Wonju Natl Univ, Dept Atmospher & Environm Sci, Kangnung 25457, South Korea; Chonnam Natl Univ, Dept Stat, Gwangju 61186, South Korea; Pohang Univ Sci & Technol, Div Environm Sci & Engn, Pohang 37673, South Korea | Kim, Hyeong-Seog/F-4496-2010; Min, Seung-Ki/B-1431-2010; Park, JeongSoo/LVR-8624-2024; Byun, Young-Hwa/JCO-1048-2023; Park, Doo-Sun/U-9448-2019; BYUN, Young-Hwa/JCO-1048-2023; KIM, MAENG-KI/C-6454-2017 | 37117659000; 35487531500; 34972911900; 34568038900; 7406091975; 7201868003; 35171145500; 57192273006 | dsrpark@knu.ac.kr;hyeongseog@kmou.ac.kr;mhkwon@kiost.ac.kr;yhbyun@korea.kr;mkkim@kongju.ac.kr;iuchung@gwnu.ac.kr;jspark@jnu.ac.kr;skmin@postech.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 9 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0.55 | 2025-07-30 | 7 | 6 | CMIP5; CMIP6; potential intensity; western North Pacific; South Korea | CMIP5; CMIP6; Potential intensity; South korea; Western north pacific | South Korea; Hurricanes; Mean square error; Storms; Thermodynamics; Tropics; Basin wide; CMIP6; Model evaluation; Pattern correlation; Performances evaluation; Potential intensity; South Korea; Thermodynamic conditions; Tropical cyclone; Western North Pacific; atmospheric dynamics; atmospheric modeling; CMIP; performance assessment; thermodynamics; tropical cyclone; Climate models | English | 2021 | 2021-09 | 10.3390/atmos12091214 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Aerosol Properties within and above the Planetary Boundary Layer across the Korean Peninsula during December 2016 | During December 2016, airborne aerosol measurements were taken at multiple heights across the Korean Peninsula to examine the vertical properties of aerosols. This study showed that aerosols above the planetary boundary layer (PBL) show similar concentrations and particle size distributions (PSDs), regardless of the relative locations in Korea. On the other hand, aerosols within the PBL differ depending on the geographical location, origin and path of the air mass. The concentrations are the highest in Seoul, followed by Gangneung, East Sea and the Yellow Sea. The known east-west aerosol gradient did not appear and the reasons are discussed in this paper. The study further shows that the aerosols of upwind regions affect the aerosols above the PBL, whereas aerosols in the PBL are affected by local sources and atmospheric conditions in addition to aerosols of upwind areas. | Jung, Eunsil; Seo, Seongkyu; Chang, Ki-Ho; Yum, Seong-Soo; Heo, Bok-Haeng | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju 37224, South Korea; DigiQuay Co Ltd, Anyang 14058, Gyeonggi Do, South Korea; Natl Inst Meteorol Sci, Jeju 63568, South Korea; Yonsei Univ, Dept Atmospher Sci, Seoul 03722, South Korea; Korea Meteorol Adm, Seoul 07062, South Korea | 55683061800; 57220870522; 36182839400; 7003842561; 6603253360 | eunsiljung@knu.ac.kr;ggaru79@gmail.com;khchang@korea.kr;ssyum@yonsei.ac.kr;happyheo93@korea.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 10 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0.09 | 2025-07-30 | 1 | 1 | vertical structure of aerosols; continental outflow regions; east-west aerosol gradient | DISTRIBUTIONS; DUST; POLLUTION | Continental outflow regions; East–west aerosol gradient; Vertical structure of aerosols | Kangnung; Kangwon; Pacific Ocean; Sea of Japan; South Korea; Yellow Sea; Atmospheric aerosols; Atmospheric thermodynamics; Aerosol measurement; Aerosol properties; Continental outflow; Continental outflow region; East–west aerosol gradient; Particles-size distributions; Planetary boundary layers; Vertical structure of aerosol; Vertical structures; aerosol property; air mass; boundary layer; concentration (composition); particle size; size distribution; Particle size | English | 2021 | 2021-10 | 10.3390/atmos12101299 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Future Projections and Uncertainty Assessment of Precipitation Extremes in the Korean Peninsula from the CMIP6 Ensemble with a Statistical Framework | Scientists occasionally predict projected changes in extreme climate using multi-model ensemble methods that combine predictions from individual simulation models. To predict future changes in precipitation extremes in the Korean peninsula, we examined the observed data and 21 models of the Coupled Model Inter-Comparison Project Phase 6 (CMIP6) over East Asia. We applied generalized extreme value distribution (GEVD) to a series of annual maximum daily precipitation (AMP1) data. Multivariate bias-corrected simulation data under three shared socioeconomic pathway (SSP) scenarios-namely, SSP2-4.5, SSP3-7.0, and SSP5-8.5-were used. We employed a model weighting method that accounts for both performance and independence (PI-weighting). In calculating the PI-weights, two shape parameters should be determined, but usually, a perfect model test method requires a considerable amount of computing time. To address this problem, we suggest simple ways for selecting two shape parameters based on the chi-square statistic and entropy. Variance decomposition was applied to quantify the uncertainty of projecting the future AMP1. Return levels spanning over 20 and 50 years, as well as the return periods relative to the reference years (1973-2010), were estimated for three overlapping periods in the future, namely, period 1 (2021-2050), period 2 (2046-2075), and period 3 (2071-2100). From these analyses, we estimated that the relative increases in the observations for the spatial median 20-year return level will be approximately 18.4% in the SSP2-4.5, 25.9% in the SSP3-7.0, and 41.7% in the SSP5-8.5 scenarios, respectively, by the end of the 21st century. We predict that severe rainfall will be more prominent in the southern and central parts of the Korean peninsula. | Shin, Yonggwan; Shin, Yire; Hong, Juyoung; Kim, Maeng-Ki; Byun, Young-Hwa; Boo, Kyung-On; Chung, Il-Ung; Park, Doo-Sun R.; Park, Jeong-Soo | Chonnam Natl Univ, Dept Math & Stat, Gwangju 61186, South Korea; Kongju Natl Univ, Dept Atmospher Sci, Gongju 32588, South Korea; Natl Inst Meteorol Sci, Seogwipo 63568, South Korea; Gangneung Wonju Natl Univ, Dept Atmospher & Environm Sci, Kangnung 25457, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea | ; Park, Doo-Sun/U-9448-2019; BYUN, Young-Hwa/JCO-1048-2023; Park, JeongSoo/LVR-8624-2024; Byun, Young-Hwa/JCO-1048-2023; KIM, MAENG-KI/C-6454-2017 | 57195979725; 57201994621; 57226663206; 7406091975; 34568038900; 7003459696; 7201868003; 37117659000; 35171145500 | syg.stat@gmail.com;shinyire@daum.net;hjy_stat@naver.com;mkkim@kongju.ac.kr;yhbyun@korea.kr;kyungon@korea.kr;iuchung@gwnu.ac.kr;dsrpark@knu.ac.kr;jspark@jnu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 1 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0.92 | 2025-07-30 | 11 | 11 | climate change; Dirichlet distribution; exceedance probability; expected waiting time; generalized extreme value distribution; heavy rainfall; L-moment estimation; return period | REGIONAL CLIMATE MODELS; EAST-ASIA; TEMPERATURE; INCREASE; EVENTS; TRENDS; INDEXES | Climate change; Dirichlet distribution; Exceedance probability; Expected waiting time; Generalized extreme value distribution; Heavy rainfall; L-moment estimation; Return period | Korea; Forecasting; Testing; Chi square statistic; Daily precipitations; Generalized extreme value distribution; Multi-model ensemble; Precipitation extremes; Statistical framework; Uncertainty assessment; Variance decomposition; CMIP; ensemble forecasting; error correction; extreme event; future prospect; multivariate analysis; performance assessment; precipitation intensity; probability; rainfall; uncertainty analysis; weather forecasting; Climate models | English | 2021 | 2021-01 | 10.3390/atmos12010097 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | High-Resolution Modeling of Mesoscale Circulation in the Atmospheric Boundary Layer over a Complex Coastal Area | We evaluated the performance of the high-resolution (333 m) Weather Research and Forecasting (WRF) model in simulating the flow structure at a complex coastal site in Boseong, South Korea, on 15 July 2018, against observations obtained from a 300 m tower and radiosonde, and analyzed the model results to interpret the measurements. The study site is surrounded by mountains, valleys, and bays, and is adjacent to the South Sea; thus, it is influenced by terrain-forced flow and thermally driven circulation. The study day was characterized by the development of nighttime low-level wind maximum (LLWM) and daytime sea breeze under weak synoptic wind conditions. Although the WRF model simulated the onset and cessation of a sea breeze later than was observed, it showed good skill in reproducing the near-surface temperatures, wind vectors, and vertical profiles of potential temperatures and wind vectors in the atmospheric boundary layer at the study site. We analyzed the model results at 05:30 and 14:30 LST when the model's performance was good for wind. At 05:30 LST, hydraulic jump produced weak wind conditions below 300 m above ground level (AGL), and westerly down-valley flow developed near the surface, leading to an LLWM. At 14:30 LST, heating over land produced a thermal high over land at 1800 m AGL, counteracting the synoptic pressure gradient, and leading to weak wind conditions at this level. We performed three sensitivity simulations to examine the dependence of flow structure on the horizontal and vertical resolution. The results show that an early-morning hydraulic jump can be simulated by applying a high-resolution model in both the horizontal and vertical grids, and the simulated onset and cessation times of the sea breeze depend on the model's resolution. The dependence of flow structure on the model resolution has been discussed. | Lim, Hee-Jeong; Lee, Young-Hee | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea | 55329559600; 56812706200 | hjyim999@gmail.com;young@knu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 12 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0 | 2025-07-30 | 0 | 0 | 300 m tower; complex coastal area; high-resolution numerical simulation; sea breeze; nighttime low-level wind maximum (LLWM) | SEA; WEATHER; TRANSPORT; BREEZES; TERRAIN; SHALLOW; SPAIN | 300 m tower; Complex coastal area; High-resolution numerical simulation; Nighttime low-level wind maximum (LLWM); Sea breeze | Boseong; South Cholla; South Korea; Atmospheric boundary layer; Atmospheric movements; Flow structure; Hydraulic jump; Landforms; Weather forecasting; 300 m tower; Coastal area; Complex coastal area; High-resolution models; High-resolution numerical simulation; Low-level winds; Nighttime low-level wind maximum; Performance; Sea-breeze; Wind conditions; atmospheric circulation; boundary layer; coastal zone; computer simulation; flow structure; radiosonde; sea breeze; weather forecasting; Coastal zones | English | 2021 | 2021-12 | 10.3390/atmos12121649 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Impact of Tropical Cyclones on Inhabited Areas of the SWIO Basin at Present and Future Horizons. Part 2: Modeling Component of the Research Program RENOVRISK-CYCLONE | The ReNovRisk-Cyclone program aimed at developing an observation network in the south-west Indian ocean (SWIO) in close synergy with the implementation of numerical tools to model and analyze the impacts of tropical cyclones (TC) in the present and in a context of climate change. This paper addresses the modeling part of the program. First, a unique coupled system to simulate TCs in the SWIO is developed. The ocean-wave-atmosphere coupling is considered along with a coherent coupling between sea surface state, wind field, aerosol, microphysics, and radiation. This coupled system is illustrated through several simulations of TCs: the impact of air-sea flux parameterizations on the evolution of TC Fantala is examined, the full coupling developed during the program is illustrated on TC Idai, and the potential of novel observations like space-borne synthetic aperture radar and sea turtles to validate the atmosphere and ocean models is presented with TC Herold. Secondly, the evolution of cyclonic activity in the SWIO during the second half of the 21st century is assessed. It was addressed both using climate simulation and through the implementation of a pseudo global warming method in the high-resolution coupled modeling platform. Our results suggest that the Mascarene Archipelago should experience an increase of TC related hazards in the medium term. | Barthe, Christelle; Bousquet, Olivier; Bielli, Soline; Tulet, Pierre; Pianezze, Joris; Claeys, Marine; Tsai, Chia-Lun; Thompson, Callum; Bonnardot, Francois; Chauvin, Fabrice; Cattiaux, Julien; Bouin, Marie-Noelle; Amelie, Vincent; Barruol, Guilhem; Calmer, Radiance; Ciccione, Stephane; Cordier, Emmanuel; Duong, Quoc-Phi; Durand, Jonathan; Fleischer-Dogley, Frauke; Husson, Romain; Lees, Edouard; Malardel, Sylvie; Marquestaut, Nicolas; Mavume, Alberto; Mekies, Dominique; Mouche, Alexis; Ravoson, Navalona Manitriniana; Razafindradina, Bruno; Rindraharisaona, Elisa; Roberts, Gregory; Singh, Manvendra; Zakariasy, Lova; Zucule, Jonas | Univ La Reunion, CNRS, Lab Atmosphere & Cyclones, Meteo France, F-97400 St Denis, France; Univ Toulouse, CNRS, IRD, Lab Aerol,UT3, F-31400 Toulouse, France; Nelson Mandela Univ, Inst Coastal Marine Res, ZA-6031 Port Elizabeth, South Africa; Univ Toulouse, CNRS, CNRM, Meteo France, F-31057 Toulouse, France; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Ctr Atmospher REmote Sensing CARE, Daegu 41566, South Korea; Direct Interreg Meteo France Ocean Indien, F-97400 St Denis, France; Univ Brest, CNRS, IFREMER, Lab Oceanog Phys & Spatiale,IRD,IUFM, F-29280 Plouzane, France; Seychelles Meteorol Author, Mahe 670311, Seychelles; Univ Paris, CNRS, Inst Phys Globe Paris, F-75005 Paris, France; Univ Colorado, Cooperat Inst Res Environm Sci, Natl Snow & Ice Data Ctr NSIDC, Boulder, CO 80304 USA; Observ Tortues Marines La Reunion, Kelonia, F-97436 St Leu, France; Observ Sci Univers La Reunion, OSU R, UAR 3365, F-97400 St Denis, France; Seychelles Islands Fdn, Mahe 670311, Seychelles; Collecte Localisat Satellites CLS, F-29280 Brest, France; Eduardo Mondlane Univ, Fac Sci, Dept Phys, Maputo 257, Mozambique; Univ Antisiranana, Inst & Observ Geophys Antisiranana, Antananarivo 101, Madagascar; Inst Super Technol Antisiranana, Antsiranana 201, Madagascar; Univ La Reunion, Lab GeoSci Reunion LGSR, F-97400 St Denis, France; Univ Calif San Diego, Scripps Inst Oceanog, San Diego, CA 92103 USA; Mauritius Oceanog Inst, Albion 95410, Mauritius; Inst Nacl Meteorol INAM, Maputo 256, Mozambique | Roberts, Greg/GWV-5653-2022; Barruol, Guilhem/A-7116-2008; Bouin, Marie-Noelle/AAV-1680-2021; Cordier, Emmanuel/N-1540-2013; Barruol, guilhem/M-8677-2019; Tsai, Chia-Lun/AHI-4361-2022 | 22133430700; 8413672100; 7801624094; 55915046600; 56910274200; 56472428200; 55474132500; 57222057977; 25823700400; 7005501673; 26645901500; 7003342377; 41560959700; 6602857511; 55915364000; 15821751300; 42360920700; 57223344911; 57194105244; 34871737900; 55344362300; 57219112242; 6506756436; 57189991309; 37061335900; 57193991940; 8538711400; 57224539320; 57224163854; 55655002400; 7403401100; 58600214600; 6506452866; 57223116496 | christelle.barthe@aero.obs-mip.fr;olivier.bousquet@meteo.fr;soline.bielli-bousquet@univ-reunion.fr;pierre.tulet@aero.obs-mip.fr;pianezze.joris@gmail.com;marine.claeys@meteo.fr;chialun@knu.ac.kr;callum-thompson@ucsb.edu;francois.bonnardot@meteo.fr;fabrice.chauvin@meteo.fr;julien.cattiaux@meteo.fr;nbouin@ifremer.fr;v.amelie@meteo.gov.sc;barruol@ipgp.fr;radiance.calmer@colorado.edu;stephane.ciccione@museesreunion.re;emmanuel.cordier@univ-reunion.fr;quoc-phi.duong@meteo.fr;durand.jonathan.2@uqam.ca;ceo@sif.sc;rhusson@cls.fr;edouard.lees@meteo.fr;sylvie.malardel@meteo.fr;nicolas.marquestaut@univ-reunion.fr;alberto.mavume@uem.mz;dominique.mekies@meteo.fr;Alexis.Mouche@ifremer.fr;ravosonnaval3@gmail.com;hbrazafindradina@ist-antsiranana.mg;elisa.rindraharisaona@univ-reunion.fr;greg.roberts@meteo.fr;msingh@moi.intnet.mu;lova.zakariasy@ist-antsiranana.mg;jnzucule@gmail.com; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 6 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0.55 | 2025-07-30 | 4 | 6 | tropical cyclone; south-west Indian ocean; cloud-resolving model; ocean-wave-atmosphere coupling; climate modeling | AIR-SEA MOMENTUM; HIGH WIND SPEEDS; BOUNDARY-LAYER; UPPER OCEAN; BULK PARAMETERIZATION; ATMOSPHERE; INTENSITY; SPRAY; SCHEME; FLUX | Climate modeling; Cloud-resolving model; Ocean–wave–atmosphere coupling; South-west Indian ocean; Tropical cyclone | Indian Ocean; Indian Ocean (Southwest); Cheloniidae; Global warming; Hurricanes; Storms; Surface waters; Synthetic aperture radar; Tropics; Climate simulation; Coherent coupling; Cyclonic activities; Model components; Observation networks; Pseudo-global warming methods; Research programs; Sea surface state; air-sea interaction; anticyclone; atmospheric modeling; climate change; climate modeling; future prospect; tropical cyclone; Climate models | English | 2021 | 2021-06 | 10.3390/atmos12060689 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Non-Stationary Effects of the Arctic Oscillation and El Nino-Southern Oscillation on January Temperatures in Korea | In recent decades, extremely cold winters have occurred repeatedly throughout the Northern Hemisphere, including the Korean Peninsula (hereafter, Korea). Typically, cold winter temperatures in Korea can be linked to the strengthening of the Siberian High (SH). Although previous studies have investigated the typical relationship between the SH and winter temperatures in Korea, this study uniquely focused on a change in the relationship, which reflects the influence of the Arctic Oscillation (AO) and El Nino-Southern Oscillation (ENSO). A significant change in the 15-year moving correlation between the SH and the surface air temperature average in Korea (K-tas) was observed in January. The correlation changed from -0.80 during 1971-1990 to -0.16 during 1991-2010. The mean sea-level pressure pattern regressed with the temperature, and a singular value decomposition analysis that incorporated the temperature and pressure supports that the negative high correlation during 1971-1990 was largely affected by AO. This connection with AO is substantiated by empirical orthogonal function (EOF) analysis with an upper-level geopotential height at 300 hPa. In the second mode of the EOF, the temperature and pressure patterns were primarily affected by ENSO during 1991-2010. Consequently, the interdecadal change in correlation between K-tas and the SH in January can be attributed to the dominant effect of AO from 1971-1990 and of ENSO from 1991-2010. Our results suggest that the relative importance of these factors in terms of the January climate in Korea has changed on a multidecadal scale. | Yoon, Jae-Seung; Chung, Il-Ung; Shin, Ho-Jeong; Jang, Kunmn-Yeong; Kim, Maeng-Ki; Park, Jeong-Soo; Park, Doo-Sun R.; Boo, Kyung-On; Byun, Young-Hwa; Sung, Hyun-Min | Gangneung Wonju Natl Univ, Nat Sci Res Inst, Kangnung 25457, South Korea; Gangneung Wonju Natl Univ, Dept Atmospher & Environm Sci, Kangnung 25457, South Korea; Kongju Natl Univ, Dept Atmospher Sci, Gongju 32588, South Korea; Chonnam Natl Univ, Dept Math & Stat, Gwangju 61186, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Natl Inst Meteorol Sci, Seogwipo 63568, South Korea | BYUN, Young-Hwa/JCO-1048-2023; Park, JeongSoo/LVR-8624-2024; KIM, MAENG-KI/C-6454-2017; Park, Doo-Sun/U-9448-2019; Byun, Young-Hwa/JCO-1048-2023 | 57223215889; 7201868003; 59881531300; 57223242576; 7406091975; 35171145500; 37117659000; 7003459696; 34568038900; 57210809003 | jsvip13@naver.com;iuchung@gwnu.ac.kr;hojeong.shin@gmail.com;orangecoral@naver.com;mkkim@kongju.ac.kr;jspark@jnu.ac.kr;dsrpark@knu.ac.kr;kyungon@korea.kr;yhbyun@korea.kr;sunghm122@korea.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 5 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0 | 2025-07-30 | 1 | 1 | extreme cold; arctic oscillation; El Nino-Southern Oscillation; Korean Peninsula; Siberian High | ASIAN WINTER MONSOON; SURFACE AIR-TEMPERATURE; COLD EURASIA PATTERN; ENSO; VARIABILITY; BLOCKING; IMPACT; CIRCULATION; CLIMATE; LINKAGE | Arctic oscillation; El Niño–Southern Oscillation; Extreme cold; Korean Peninsula; Siberian High | Korea; Atmospheric pressure; Orthogonal functions; Sea level; Singular value decomposition; Empirical orthogonal function analysis; Geo-potential heights; Mean sea level pressures; Non-stationary effects; Northern Hemispheres; Singular value decomposition analysis; Surface air temperatures; Temperature and pressures; air temperature; air-sea interaction; Arctic Oscillation; El Nino-Southern Oscillation; paleoclimate; sea level pressure; Climatology | English | 2021 | 2021-05 | 10.3390/atmos12050538 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Triterpenoids from Celastrus orbiculatus Thunb. inhibit RANKL-induced osteoclast formation and bone resorption via c-Fos signaling | Fourteen triterpenes, lup-20(29)-ene-3 beta,6 beta-diol (1), betulin (2), lupeol caffeate (3), 3 beta-caffeoyloxylup-20(29)-en-6 alpha-ol (4), betulin-3 beta-yl-caffeate (5), 3 beta-trans-feruloylbetulin (6), betulinaldehyde 3-caffeate (7), 3-O-trans-caffeoylbetulinic acid (8), dammarenediol II 3-caffeate (9), 12-oleanene-3 beta,6 alpha-diol (10), 11 alpha-hydroxy-3 beta-amyrin (11), nivadiol (12), 29-hydroxyfriedelin (13), and celastrusin A (14) were isolated fromCelastrus orbiculatusThunb. and evaluated for their activity on receptor activator of nuclear factor kappa B ligand (RANKL)-induced osteoclast differentiation in bone marrow macrophages (BMMs). Compounds betulin (2), betulin-3 beta-yl-caffeate (5), 3 beta-trans-feruloylbetulin (6), and 3-O-trans-caffeoylbetulinic acid (8) significantly inhibited osteoclast formation in a dose-dependent manner. Among these, betulin-3 beta-yl-caffeate (5) exhibited the most potent inhibitory activity. We demonstrated that betulin-3 beta-yl-caffeate (5) suppressed F-actin-ring formation and bone resorption activity. At the molecular level, betulin-3 beta-yl-caffeate (5) inhibited RANK-induced expression of c-Fos and the induction of nuclear factor of activated T cells 1 (NFATc1), a key transcription factor for osteoclast formation, and it also downregulated mRNA expression of osteogenesis-associated marker genes including tartrate-resistant acid phosphatase (TRAP), dendritic cell-specific transmembrane protein (DC-STAMP), and matrix metalloprotein (MMP). These results indicate that betulin-3 beta-yl-caffeate (5) may be a promising candidate for the treatment of osteoclast-related diseases such as osteoporosis.

| ○ | ○ | Article | Urban Effect on Sea-Breeze-Initiated Rainfall: A Case Study for Seoul Metropolitan Area | We examined the sea-breeze-initiated rainfall in the Seoul Metropolitan area (SMA) on 6 July 2017 using the weather research and forecasting (WRF) model. The model captures the arrival of the sea breeze front (SBF), the development of afternoon rainfall in the SMA, and the location of the sea-breeze-initiated maximum rainfall in the northeastern SMA reasonably well but overestimates the subsequent rainfall. We conducted sensitivity tests to better understand the urban effect on the sea-breeze-initiated rainfall event. Through factor separation analysis, we first examined the explicit role of sea and urban effect on sea-breeze-initiated rainfall. The results show that the interaction of sea and urban effects cause rainfall in the northwest and northeast of the SMA, indicating that both urban heat island circulation (UHIC) and sea breeze play an important role in the study case's rainfall. We further examined the relative role of urban roughness and anthropogenic heat on the sea-breeze-initiated rainfall through factor separation analysis. Both anthropogenic heat and urban roughness play a role in increasing precipitation in the northeastern area of the SMA, with a larger contribution of anthropogenic heat than urban roughness. The relationship between low-level convergence at the SBF and urban factors is discussed. | Choi, Yuna; Lee, Young-Hee | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea | 57221762910; 56812706200 | zzzzz0415@naver.com;young@knu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 12 | 11 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 3.11 | 60.4 | 0.37 | 2025-07-30 | 4 | 5 | afternoon rainfall; sea breeze; UHIC | HEAT-ISLAND; NUMERICAL-MODEL; PRECIPITATION; URBANIZATION; CONVECTION; IMPACT; CIRCULATIONS; REGION; WINTER | Afternoon rainfall; Sea breeze; UHIC | Seoul [Seoul (ADS)]; Seoul [South Korea]; South Korea; Atmospheric temperature; Factor analysis; Weather forecasting; Afternoon rainfall; Anthropogenic heat; Case-studies; Sea-breeze; Sea-breeze fronts; Seoul metropolitan area; Separation analysis; Urban effect; Urban heat island circulation; Weather research and forecasting models; heat island; metropolitan area; precipitation (climatology); rainfall; sea breeze; Rain | English | 2021 | 2021-11 | 10.3390/atmos12111483 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
