| ○ | ○ | Article | Ovicidal potential of plant extract mixtures against the Asian spongy moth (Lymantria dispar asiatica) | The Asian spongy moth (ASM, Lymantria dispar asiatica) is a destructive pest of forests, agricultural fields, and urban areas. Plant extract mixtures were evaluated as alternative tools for integrated pest management targeting the overwintering eggs of ASM. When formulated with an adjuvant able to penetrate the hairy egg mass, plant extract mixtures inhibited egg hatching. The extract mixture (cinnamon extract 5% + citronella oil 10% + citrus oil 30% + derris extract 10% + neem extract 20% + penetrating surfactant 25%) with the highest ovicidal activity (97.6% mortality) is a potential botanical insecticide for use against ASM eggs. Susceptibility to mortality from plant extract mixtures increased with egg maturation. Optimal timing for control of overwintering ASM eggs corresponded to the period in spring when larvae inside eggs were fully differentiated. These results will help improve control efficacy with a day-degree model that predicts egg hatch as well as future development nano-formulations. | Lee, Young Su; Hwang, Hwal-Su; Lee, Kyeong-Yeoll; Lee, Hee-A; Lim, Un Taek | Gyeonggi Do Agr Res & Extens Serv, Hwaseong, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Daegu, South Korea; Andong Natl Univ, Dept Plant Med, Andong, South Korea | Lee, Young Su/JFA-8669-2023 | 57199023188; 57204055221; 57217153096; 57814517800; 57202314562 | utlim@andong.ac.kr; | JOURNAL OF ASIA-PACIFIC ENTOMOLOGY | J ASIA-PAC ENTOMOL | 1226-8615 | 1876-7990 | 26 | 2 | SCIE | ENTOMOLOGY | 2023 | 1.1 | 57.3 | 0.31 | 2025-06-25 | 3 | 2 | Lymantria dispar asiatica; Eggs; Plant extract mixtures; Ovicidal activity | GYPSY-MOTH; LEPIDOPTERA; METHOXYFENOZIDE; DIAPAUSE; MECHANISM; LARVAE; KK-42; PESTS | Eggs; Lymantria dispar asiatica; Ovicidal activity; Plant extract mixtures | English | 2023 | 2023-06 | 10.1016/j.aspen.2023.102102 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Practice Patterns of Colorectal Polypectomy in Pediatric Endoscopic Specialists in South Korea: A Nationwide Survey Study | Purpose: Total colonoscopy is recommended if colorectal polyps are clinically suspected. This study aimed to investigate the performance status of pediatric colonoscopic polypectomy in Korea.Methods: We surveyed pediatric endoscopic specialists who perform colonoscopic polypectomy in Korea using a questionnaire of 13 questions on pediatric colonoscopic polypectomy performance status.Results: The survey was conducted at 45 institutions, and 32 specialists (71.1%) responded. Among the respondents, 31.2% (10/32) said colonoscopy was performed in all age groups, while 12.5% (4/32) said sigmoidoscopy was performed in all age groups. Meanwhile, 56.2% (18/32) said that sigmoidoscopy was performed in young children, while colonoscopy was performed in older children. Among them, 38.9% (7/18) believe that 4-6 years were young, and 44.5% (8/18) believe that 7-9 years were young. Regarding surveillance examinations, 21.9% (7/32) said they would perform a surveillance colonoscopy or sigmoidoscopy in the future if less than five juvenile polyps were found in the colon. Meanwhile, if less than five adenomatous polyps were found in the colon, 93.8% (30/32) said they would perform surveillance colonoscopy or sigmoidoscopy in the future.Conclusion: More than half of the pediatric endoscopic specialists in Korea choose between a colonoscopy and sigmoidoscopy depending on the patient's age, contrary to the generally accepted recommendation of total colonoscopy if colorectal polyps are suspected in children and adolescents. In this survey, most pediatric endoscopists used the age range of 4-9 years as the reference age. | Lee, Yoon; Choi, Sujin; Kang, Ben | Korea Univ, Dept Pediat, Anam Hosp, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, 680 Gukchaebosang Ro, Daegu, South Korea | 康, 奔/JMQ-0812-2023 | 55588945800; 57223972405; 57194823199 | benkang@knu.ac.kr; | PEDIATRIC GASTROENTEROLOGY HEPATOLOGY & NUTRITION | PEDIATR GASTROENTERO | 2234-8646 | 2234-8840 | 26 | 1 | ESCI | PEDIATRICS | 2023 | 1.3 | 57.3 | 0 | 2025-06-25 | 1 | 0 | Colonic polyps; Colonoscopy; Sigmoidoscopy; Pediatrics | COLONIC POLYPS | Colonic polyps; Colonoscopy; Pediatrics; Sigmoidoscopy | English | 2023 | 2023-01 | 10.5223/pghn.2023.26.1.15 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Taxonomic revision of the genus Aulonocarabus (Coleoptera; Carabidae), with a phylogenetic analysis from South Korea | Previous studies reported four species and eight subspecies of the genus Aulonocarabus in South Korea. However, their morphological classification is difficult because of high morphological similarity. Our re-examination based on detailed morphological comparison confirmed that members of this group can be distinguished by their fully inflated endophallic structure and elytral sculpture. In addition, we performed molecular phylogenetic analysis using mitochondrial ND5. Based on our results, we have revised the morphological keys of this group and propose an intraspecific classification of A. semiopacus that contains distinct regional subspecies with regard to external morphology and molecular phylogeny. Besides, distribution maps, descriptions, and photographs of adult and of male genitalia are provided. | Kwon, Taeyeong; Choi, Eun Young; Kim, Myeonghwan; Choi, Jong Bong; Kim, Myeong Cheol; Lee, Hee Soo; Moon, KyungHwan; Kim, Young Ho; Park, Jong Kyun | Kyungpook Natl Univ, Dept Ecol Sci, Sangju, South Korea; Kyungpook Natl Univ, Dept Vector Entomol, Sangju, South Korea; Kyungpook Natl Univ, Dept Entomol, Sangju, South Korea; Kyungpook Natl Univ, Coll Ecol & Environm Sci, Dept Entomol, Sangju 37224, South Korea | Choi, Eun-Young/JXO-0422-2024 | 57224825878; 57026862700; 57224780236; 57193335227; 57491840100; 58315082100; 57202874378; 58516491300; 37661967000 | entopark@knu.ac.kr; | JOURNAL OF ASIA-PACIFIC ENTOMOLOGY | J ASIA-PAC ENTOMOL | 1226-8615 | 1876-7990 | 26 | 2 | SCIE | ENTOMOLOGY | 2023 | 1.1 | 57.3 | 0 | 2025-06-25 | 0 | 0 | Carabidae; Aulonocarabus; Endophallus; Mitochondrial ND5; Korea | MITOCHONDRIAL ND5 GENE; BEETLES COLEOPTERA; CLASSIFICATION; EVOLUTION; SEQUENCES; VIETNAM | Aulonocarabus; Carabidae; Endophallus; Korea; Mitochondrial ND5 | English | 2023 | 2023-06 | 10.1016/j.aspen.2023.102098 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The role of field-collected cues in the host recognition of twig girdlers (Oncideres rhodosticta) on honey mesquite (Prosopis glandulosa) | Conspecific gravid females integrate volatile organic compounds (VOCs) to exploit potential oviposition sites; the role of VOCs has not been examined on twig girdlers, Oncideres rhodosticta, and honey mesquite, Prosopis glandulosa. To examine the host selection behavior of female twig girdlers, we examined the preference and searching time between healthy and girdled twigs of honey mesquites in New Mexico, USA. Among 21 different volatile organic compounds, female twig girdlers reacted to six chemical compounds from girdled twigs and four from healthy twigs. While females responded to Heptanal, (E)-2-Heptenal, and Linalool oxide on both healthy and girdled twigs, they also reacted to one healthy specific compound and two girdled specific compounds. Female twig girdlers distinguished healthy twigs over girdled twigs with faster searching time. Our finding demonstrates VOCs in the genus Oncideres for the first time, providing additional empirical information to help decide on the biological control potential of possible agents during the pre-release risk assessment. | Park, Ikju; Thompson, David C. | New Mexico State Univ, Dept Entomol Plant Pathol & Weed Sci, Las Cruces, NM 88003 USA; Kyungpook Natl Univ, Dept Plant Med, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Plant Med, Daegu 41566, South Korea | 57200320797; 57209176379 | ikjupark@knu.ac.kr; | JOURNAL OF ASIA-PACIFIC ENTOMOLOGY | J ASIA-PAC ENTOMOL | 1226-8615 | 1876-7990 | 26 | 1 | SCIE | ENTOMOLOGY | 2023 | 1.1 | 57.3 | 0 | 2025-06-25 | 0 | 0 | Host recognition; Olfactory cues; VOCs; Oncideres rhodosticta; Prosopis | PLANT-RESPONSES; VOLATILES; ATTRACTION; COLEOPTERA; INSECTS | Host recognition; Olfactory cues; Oncideres rhodosticta; Prosopis; VOCs | English | 2023 | 2023-03 | 10.1016/j.aspen.2022.102032 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Extract of the bioconverted fine root of ginseng induces apoptosis and cell cycle arrest in mouse colon cancer cells | Cancer is the major cause of death worldwide, and the anticancer effect of ginseng and its main root has been studied. However, study of fine root of ginseng (FRG) is still insufficient. The purpose of this study was to discover a new anticancer effect from FRG, which does not show an anticancer effect, through a bioconversion technique. We measured and compared cell viability in FRG- and bioconverted fine root of ginseng (BFRG)-stimulated CT26 cells to investigate differences caused by bioconversion. Cell viability of CT26 was suppressed upon treatment with BFRG, unlike FRG. The effect of BFRG on apoptosis and cell cycle arrest was investigated by flow cytometry. BFRG-stimulated CT26 cells showed an increased apoptotic cells and cell cycle arrest. Additionally, BFRG induced mitochondrial impairment by reducing the expression of anti-apoptosis protein Bcl-2. When confirming the signaling pathway, it was found that the p38 MAPK pathway was activated by BFRG. Collectively, our results reveal anticancer effects against colorectal cancer and represent potential targets for anticancer drug development. | Seo, Yeonju; Chae, Jongbeom; Nam, Ju-Ock | Kyungpook Natl Univ, Dept Food Sci & Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Tailored Food Technol, Daegu 41566, South Korea | 58042612000; 57204499421; 7201496105 | namjo@knu.ac.kr; | APPLIED BIOLOGICAL CHEMISTRY | APPL BIOL CHEM | 2468-0834 | 2468-0842 | 66 | 1 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 2.3 | 57.5 | 0 | 2025-06-25 | 0 | 0 | Colon cancer; Fine root of ginseng; Apoptosis; Cell cycle arrest | Apoptosis; Cell cycle arrest; Colon cancer; Fine root of ginseng | Bioconversion; Cancer cells; Diseases; Anti-apoptosis; Anticancer effects; Apoptotic cells; Causes of death; Cell viability; Cell-cycle arrest; Colon cancer; Colon cancer cells; Fine root of ginseng; Fine roots; Cell death | English | 2023 | 2023-09-17 | 10.1186/s13765-023-00818-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Assessment of the Spatiotemporal Changes in the Extreme Precipitation Climate Indices over the Chungcheong Region of South Korea during 1973-2020 | This study analyzed the changes and trends in twelve extreme precipitation-based climate indices obtained using daily data from 10 synoptic stations in the Chungcheong region of South Korea during the 1973-2020 period. The climate indices were used to assess the trends in the extreme precipitation characteristics of duration, frequency, and intensity using the innovative trend analysis (ITA) method. The results of the ITA were further compared with two other non-parametric test methods such as Mann-Kendall (MK) and Spearman's rho (SR). The results showed that most stations exhibited significant increasing trends in all the investigated climate indices at a 95% confidence level as indicated by the ITA method, with only a few stations indicating significant decreasing trends in R95p, R99p, Rx3day, and Rx5day. The sub-trend analysis further revealed the dominance of neutral behavior around the low-value cluster, especially for the extreme precipitation duration. At the same time, increasing trends dominate the high-value cluster at most stations. Meanwhile, only R10mm, R99p, and R95p exhibited monotonic trends in the Boeun and Seosan stations, respectively. Further, the ITA exhibited superior performance over the MK and SR methods by indicating the presence of more significant trends in the climate indices at most stations. The distribution of the extreme precipitation indices for duration, frequency, and intensity indicate the pronounced risk of flood conditions around the north-central and some parts of southern regions, while the western region indicates a potential drought risk, which could greatly impact the water resources and consequently agricultural activities in the study area. The results of this study provide essential information for addressing the climate-related problems of water resource management and agriculture in the study area and other related climatic regions. | Cho, Hyungon; Adelodun, Bashir; Kim, Hyo-Jeong; Kim, Gwangseob | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240003, Nigeria; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | Adelodun, Bashir/O-2941-2018 | 57871732100; 57193774482; 57203629899; 56460622700 | chohg@knu.ac.kr;adelodun.b@unilorin.edu.ng;kimhjgg@knu.ac.kr;kimgs@knu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 14 | 12 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2023 | 2.5 | 57.7 | 0.18 | 2025-06-25 | 1 | 1 | extreme climate indices; trend analysis; innovative trend analysis; spatiotemporal variability | TREND ANALYSIS; MANN-KENDALL; TEMPERATURE; VARIABILITY; RAINFALL; TESTS | extreme climate indices; innovative trend analysis; spatiotemporal variability; trend analysis | South Korea; Climate change; Information management; Precipitation (meteorology); Water management; Climate index; Extreme climate index; Extreme climates; Extreme precipitation; Innovative trend analyse; Innovative trends; South Korea; Spatiotemporal variability; Trend analysis; climate modeling; extreme event; innovation; numerical model; precipitation (climatology); regional climate; spatiotemporal analysis; trend analysis; Agriculture | English | 2023 | 2023-12 | 10.3390/atmos14121718 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Extreme Dry and Wet Events in the Pacific Region of Colombia estimated in the 21st Century Based on the Standardized Precipitation Index and CORDEX Climate Projections | The Pacific region of Colombia is known to be one of the most vulnerable to changes in precipitation patterns. A study was conducted using standardized precipitation index (SPI) analyses to understand the potential changes in precipitation in this region during the 21st century. The analyses were conducted using historical precipitation data from 1950 to 2005 and projected precipitation data from 2022 to 2100 under the Coordinated Regional Climate Downscaling Experiment (CORDEX) climate scenarios (RCP 4.5 and RCP 8.5). The results of the study showed that compared to historical data, SPI3 precipitation in this region is predicted to increase by 2040 under both climatic scenarios. However, in the 2041-2070 period, the region is expected to be wetter under RCP 8.5, although the difference between the two scenarios was not statistically significant. Similarly, SPI 6 precipitation is predicted to increase in the 2022-2040 and 2071-2100 periods under both scenarios. SPI 12 precipitation is also predicted to increase in the 2022-2040 period under RCP 4.5. In the 2041-2070 period, dryness is predicted to be more frequent under RCP 4.5, and wetness is predicted under RCP 8.5. The findings of this study can help in determining the most pertinent reference periods and computation time increments for evaluating the effects of future climate change on agricultural production and food security in the Pacific region of Colombia. It suggests that changes in precipitation patterns are likely to occur in the coming decades, which may significantly impact crop growth, water availability, and other aspects of agricultural production. | Chaulagain, Deepak; Aroca, Oscar Fernando Meneses; Same, Noel Ngando; Yakub, Abdulfatai Olatunji; Nsafon, Benyoh Emmanuel Kigha; Suh, Dongjun; Triolo, Jin Mi; Huh, Jeung-Soo | Kyungpook Natl Univ, Grad Sch, Dept Convergence & Fus Syst Engn, Sangju 37224, South Korea; Kyungpook Natl Univ, Inst Global Climate Change & Energy, Grad Sch, Dept Energy Convergence & Climate Change, Daegu 41566, South Korea; Gyeongsang Natl Univ, Future Convergence Technol Res Inst, Dept Energy Engn, 33 Dongjin Ro, Jinju 52828, South Korea | 57208742538; 58120041100; 57895613600; 57894905100; 57211664452; 36613529600; 47862380100; 7102258915 | jshuh@knu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 14 | 2 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2023 | 2.5 | 57.7 | 0.71 | 2025-06-25 | 4 | 4 | drought; extreme events; precipitation; CORDEX; climate change; representative concentration pathways | DROUGHT; SPI; IMPACT; TRENDS | climate change; CORDEX; drought; extreme events; precipitation; representative concentration pathways | Colombia; Agriculture; Food supply; Stream flow; Agricultural productions; Colombia; Coordinated regional climate downscaling experiment; Down-scaling; Extreme events; Precipitation data; Precipitation patterns; Regional climate; Representative concentration pathway; Standardized precipitation index; climate change; climate prediction; downscaling; drought; extreme event; precipitation (climatology); twenty first century; Climate change | English | 2023 | 2023-02 | 10.3390/atmos14020260 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Performance-Based Evaluation of CMIP5 and CMIP6 Global Climate Models and Their Multi-Model Ensembles to Simulate and Project Seasonal and Annual Climate Variables in the Chungcheong Region of South Korea | Extreme climate change events are major causes of devastating impacts on socioeconomic well-being and ecosystem damage. Therefore, understanding the performance of appropriate climate models representing local climate characteristics is critical for future projections. Thus, this study analyses the performance of 24 GCMs from the Coupled Model Intercomparison Project Phases 5 and 6 (CMIP5 and 6) and their multi-model ensembles in simulating climate variables including average rainfall, maximum (Tmax), and minimum (Tmin) temperatures at annual and seasonal scales over the Chungcheong region of South Korea from 1975 to 2015. A trend analysis was conducted to estimate the future trends in climate variables in the 2060s (2021-2060) and 2080s (2061-2100). Inverse distance weighting and quantile delta mapping were applied to bias-correct the GCM data. Further, six major evaluating indices comprising temporal and spatial performance assessments were used, after which a comprehensive GCM ranking was applied. The results showed that CMIP6 models performed better in simulating rainfall, Tmax, and Tmin at both temporal and spatial scales. For CMIP5, the top three performing models were GISS, ACCESS1-3, and MRI-CGCM3 for rain; CanESM2, GISS, and MPI-ESM-L-R for Tmax; and GFDL, MRI-CGCM3, and CanESM2 for Tmin. However, the top three performing models in the CMIP6 were MRI-ESM2-0, BCCCSM, and GFDL for rain; MIROC6, BCCCSM, and MRI-ESM2-0 for Tmax, and GFDL, MPIESMHR, and MRI-ESM2-0 for Tmin. The multi-model ensembles (an average of the top three GCMs) performed better in simulating rain and Tmin for both CMIP5 and CMIP6 compared with multi-model ensembles (an average of all the GCMs), which only performed slightly better in simulating Tmax. The trend analysis of future projection indicates an increase in rain, Tmax, and Tmin; however, with distinct changes under similar radiative forcing levels in both CMIP5 and CMIP6 models. The projections under RCP4.5 and RCP8.5 increase more than the SSP2-4.5 and SSP5-8.5 scenarios for most climate conditions but are more pronounced, especially for rain, under RCP8.5 than SSP5-8.5 in the far future (2080s). This study provides insightful findings on selecting appropriate GCMs to generate reliable climate projections for local climate conditions in the Chungcheong region of South Korea. | Adelodun, Bashir; Ahmad, Mirza Junaid; Odey, Golden; Adeyi, Qudus; Choi, Kyung Sook | Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240003, Nigeria; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | ; Adelodun, Bashir/O-2941-2018; Odey, Golden/MVV-6310-2025; Ahmad, Mirza/AAD-5982-2020 | 57193774482; 57201479907; 57211444984; 58672628000; 54392662900 | adelodun.b@unilorin.edu.ng;agri.junaid1205@gmail.com;goldenodey@knu.ac.kr;adeyi.qudus.tech@gmail.com;ks.choi@knu.ac.kr; | ATMOSPHERE | ATMOSPHERE-BASEL | 2073-4433 | 14 | 10 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2023 | 2.5 | 57.7 | 1.42 | 2025-06-25 | 9 | 9 | climate change; CMIP5; CMIP6; multi-model ensembles; quantile mapping; performance metrics; statistical techniques | PRECIPITATION; TEMPERATURE; TREND | climate change; CMIP5; CMIP6; multi-model ensembles; performance metrics; quantile mapping; statistical techniques | South Korea; Atmospheric radiation; Climate change; Climate models; Mapping; Climate variables; CMIP5; CMIP6; Local climate; Multi-model ensemble; Performance; Performance metrices; Quantile mapping; South Korea; Statistical techniques; climate conditions; climate modeling; climate variation; CMIP; computer simulation; ensemble forecasting; global climate; performance assessment; radiative forcing; trend analysis; Rain | English | 2023 | 2023-10 | 10.3390/atmos14101569 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A smartphone-based application for cough counting in patients with acute asthma exacerbation | Background: While tools exist for objective cough counting in clinical studies, there is no available tool for objective cough measurement in clinical practice. An artificial intelligence (AI)-based cough count system was recently developed that quantifies cough sounds collected through a smartphone application. In this prospective study, this AI-based cough algorithm was applied among real-world patients with an acute exacerbation of asthma. Methods: Patients with an acute asthma exacerbation recorded their cough sounds for 7 days (2 consecutive hours during awake time and 5 consecutive hours during sleep) using CoughyTM smartphone application. During the study period, subjects received systemic corticosteroids and bronchodilator to control asthma. Coughs collected by application were counted by both the AI algorithm and two human experts. Subjects also provided self-measured peak expiratory flow rate (PEFR) and completed other outcome assessments [e.g., cough symptom visual analogue scale (CS-VAS), awake frequency, salbutamol use] to investigate the correlation between cough and other parameters.Results: A total of 1,417.6 h of cough recordings were obtained from 24 asthmatics (median age =39 years). Cough counts by AI were strongly correlated with manual cough counts during sleep time (rho =0.908, P<0.001) and awake time (rho =0.847, P<0.001). Sleep time cough counts were moderately to strongly correlated with CS-VAS (rho =0.339, P<0.001), the frequency of waking up (rho =0.462, P<0.001), and salbutamol use at night (rho =0.243, P<0.001). Weak-to-moderate correlations were found between awake time cough counts and CS-VAS (rho =0.313, P<0.001), the degree of activity limitation (rho =0.169, P=0.005), and salbutamol use at awake time (rho =0.276, P<0.001). Neither awake time nor sleep time cough counts were significantly correlated with PEFR.Conclusions: The strong correlation between cough counts using the AI-based algorithm and human experts, and other indicators of patient health status provides evidence of the validity of this AI algorithm for use in asthma patients experiencing an acute exacerbation. Study findings suggest that CoughyTM could be a novel solution for objectively monitoring cough in a clinical setting. | Shim, Ji-Su; Kim, Byung-Keun; Kim, Sae-Hoon; Kwon, Jae-Woo; Ahn, Kyung-Min; Kang, Sung-Yoon; Park, Han-Ki; Park, Heung-Woo; Yang, Min-Suk; Kim, Min-Hye; Lee, Sang Min | Ewha Womans Univ, Coll Med, Dept Internal Med, 260 Gonghang Daero, Seoul 07804, South Korea; Korea Univ, Coll Med, Dept Internal Med, Div Pulmonol Allergy & Crit Care Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seongnam, South Korea; Kangwon Natl Univ, Sch Med, Dept Internal Med, Chunchon, South Korea; SMG SNU Boramae Med Ctr, Dept Internal Med, Seoul, South Korea; Gachon Univ, Gil Med Ctr, Dept Internal Med, Incheon, South Korea; Kyungpook Natl Univ, Sch Med, Dept Allergy & Clin Immunol, Daegu, South Korea; Seoul Natl Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Gachon Univ, Gil Med Ctr, Dept Internal Med, Div Pulmonol & Allergy, 21 Namdong Daero 774beon Gil, Incheon 21565, South Korea | Park, Han-Ki/AAY-3102-2020; Kang, Sung-Yoon/AAG-7523-2020; Kim, Byung-Keun/N-4256-2018; Kim, Sae/AAR-3907-2020 | 57193221759; 36608393400; 35198322400; 57204538197; 55421364200; 55492809000; 57218664064; 7601567361; 7404927140; 58045929900; 55913470000 | mineyang81@ewha.ac.kr;allergylung@gilhospital.com;sangminlee77@naver.com; | JOURNAL OF THORACIC DISEASE | J THORAC DIS | 2072-1439 | 2077-6624 | 15 | 7 | SCIE | RESPIRATORY SYSTEM | 2023 | 2.1 | 57.9 | 1.27 | 2025-06-25 | 4 | 7 | Cough; asthma exacerbation; artificial intelligence (AI); objective cough frequency | ANTAGONIST | artificial intelligence (AI); asthma exacerbation; Cough; objective cough frequency | antihistaminic agent; beta 2 adrenergic receptor stimulating agent; bronchodilating agent; cholinergic receptor blocking agent; corticosteroid; leukotriene receptor blocking agent; mannitol; methacholine; salbutamol; adult; algorithm; Article; artificial intelligence; asthma; clinical article; controlled study; corticosteroid therapy; coughing; disease exacerbation; female; human; low drug dose; male; outcome assessment; peak expiratory flow; prospective study; sleep time; systemic therapy; visual analog scale; wakefulness | English | 2023 | 2023-07 | 10.21037/jtd-22-1492 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Clinical implications of wheezing in patients with chronic obstructive pulmonary disease | Background: Studies on the prevalence of wheezing in both the asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) and non-ACO groups, as well as the clinical characteristics of wheezing patients in each group, are rare. We examined the prevalence of wheezing in ACO patients and non-ACO patients, respectively. In addition, we aimed to determine clinical characteristics of patients with wheezing compared to those without wheezing in the ACO and non-ACO groups.Methods: We analyzed the data from the Korean COPD Subgroup Study (KOCOSS), a multicenter prospective cohort. We classified patients into four groups according to whether they were ACO patients or had self-reported wheezing based on the patient's answer to the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C): ACO with wheezing, ACO without wheezing, non-ACO with wheezing, and non-ACO without wheezing. Clinical characteristics and exacerbations during 1-year follow up were compared among four groups.Results: Wheezing was present in about 56% of patients in the ACO and non-ACO groups. In both groups, patients with wheezing exhibited more severe symptoms, worse lung function, and a higher risk of exacerbation than those without wheezing. There was no association between blood eosinophil count and wheezing in both the ACO and non-ACO groups. During 1-year follow-up, the ACO with wheezing group experienced exacerbations the most frequently, followed by the non-ACO with wheezing group. Moreover, wheezing was an independent predictor of the risk of exacerbation in patients with COPD, irrespective of both the ACO phenotype and the severity of airflow limitation. The exacerbation risk was higher in COPD patients who experienced wheezing more frequently. Conclusions: Wheezing, reflecting more prominent airflow limitation and predicting exacerbation development, may serve as a severe phenotype of COPD rather than being indicative of an ACO phenotype. | Seo, Hyewon; Kim, Youlim; Jang, Jong Geol; Ahn, June Hong; Ra, Seung Won; Park, Yong Bum; Ha Yoo, Kwang; Jung, Ki Suck; Lee, Jaehee | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med,Div Pulm & Crit Care Med, Daegu, South Korea; Konkuk Univ, Konkuk Univ Hosp, Sch Med, Dept Internal Med,Div Pulm Allergy & Crit Care Med, Seoul, South Korea; Yeungnam Univ, Med Ctr, Dept Internal Med, Div Pulmonol & Allergy, Daegu, South Korea; Univ Ulsan, Ulsan Univ Hosp, Coll Med, Dept Internal Med,Div Pulmonol, Ulsan, South Korea; Hallym Univ, Kangdong Sacred Heart Hosp, Dept Internal Med, Div Pulm Allergy & Crit Care Med, Seoul, South Korea; Hallym Univ, Sacred Heart Hosp, Dept Internal Med, Div Pulm Allergy & Crit Care Med, Anyang, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med,Div Pulm & Crit Care Med, 130 Dongdeok Ro, Daegu 41944, South Korea | Lee, Jaehee/S-1697-2018; Lee, Yoojin/AAB-9799-2022; Ra, Seung Won/KYI-0974-2024; Jung, Ki-Suck/AAN-2473-2021; Ahn, June/AAB-3093-2019 | 55612130200; 57316627700; 56645456400; 56645445800; 36515395700; 57212764499; 57693301700; 7402479869; 13805476000 | jaelee@knu.ac.kr; | JOURNAL OF THORACIC DISEASE | J THORAC DIS | 2072-1439 | 2077-6624 | 15 | 11 | SCIE | RESPIRATORY SYSTEM | 2023 | 2.1 | 57.9 | 0 | 2025-06-25 | 1 | 1 | Chronic obstructive pulmonary disease (COPD); wheezing; asthma-COPD overlap (ACO); exacerbation | COPD; ASTHMA; VALIDATION; PHENOTYPE; SYMPTOMS; HEALTH; IMPACT | asthma-COPD overlap (ACO); Chronic obstructive pulmonary disease (COPD); exacerbation; wheezing | beta 2 adrenergic receptor stimulating agent; bronchodilating agent; corticosteroid; long acting drug; muscarinic receptor blocking agent; adult; age; allergic rhinitis; Article; asthma; body mass; bronchiectasis; chest infection; chronic obstructive lung disease; clinical feature; cohort analysis; combination drug therapy; comorbidity; confidence interval; controlled study; COPD assessment test; cross-sectional study; current smoker; demographics; diabetes mellitus; diffusing capacity for carbon monoxide; disease exacerbation; disease severity; emergency ward; emphysema; eosinophil count; female; follow up; forced expiratory volume; forced vital capacity; frequency analysis; heart failure; heart infarction; hospital patient; hospitalization; human; hypertension; lung function test; lung tuberculosis; major clinical study; male; Modified Medical Research Council Dyspnea Scale; multicenter study; phenotype; prevalence; prospective study; respiratory airflow; self report; sex; six minute walk test; South Korean; spirometry; St. George Respiratory Questionnaire; thorax radiography; tuberculosis; wheezing | English | 2023 | 2023-11 | 10.21037/jtd-23-1031 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Hemoptysis as the presenting manifestation of bronchiectasis-associated hospitalization in Korea | Background: Patients with bronchiectasis commonly experience disease exacerbations, which cause significant morbidity and mortality. However, data regarding the clinical features of bronchiectasis patients hospitalized with hemoptysis are scarce. Methods: We retrospectively collected the data of patients with bronchiectasis-associated hospitalization at a tertiary referral center in Korea, and classified them into the hemoptysis and infective exacerbation (IE) groups. The presence of hemoptysis was defined as a volume of expectorated blood larger than 10 mL per 24 hours. The clinical, radiological, and laboratory parameters were compared between the two groups.Results: Patients were classified into the hemoptysis [267 (54.5%)] and IE [223 (45.5%)] groups. Among the 44 patients of the hemoptysis group, 37 (84.1%) presented with hemoptysis than with IE at the recurrent episode. The hemoptysis group had a significantly lower 30-day mortality than that of the IE group. Previous pulmonary tuberculosis (TB), mycetoma, and bronchial artery hypertrophy were independently associated with the hemoptysis group. In contrast, male sex, poor performance status, colonization of Pseudomonas aeruginosa, & GE;3 involved lobes, cystic bronchiectasis, and emphysema were inversely associated with the hemoptysis group. The absence of hemoptysis was one of the independent predictors of 30-day mortality in patients with bronchiectasis-associated hospitalization.Conclusions: In Korea, bronchiectasis patients hospitalized with hemoptysis exhibit a distinct phenotype, and are more likely to have previous pulmonary TB, mycetoma, and bronchial artery hypertrophy. Hemoptysis is associated with a lower risk of short-term mortality compared to IE in bronchiectasisassociated hospitalization. | Seo, Hyewon; Cha, Seung-Ick; Park, Jongmin; Lim, Jae-Kwang; Park, Ji-Eun; Choi, Sun Ha; Lee, Yong Hoon; Yoo, Seung-Soo; Lee, Shin-Yup; Lee, Jaehee; Kim, Chang-Ho; Park, Jae-Yong | Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea | Lee, Jaehee/S-1697-2018; Lee, Jungmin/KHT-2438-2024 | 55612130200; 35227126400; 57216463879; 55515341400; 57195437358; 57199723585; 57199022948; 56479781600; 49863712700; 13805476000; 7409873555; 58360293800 | sicha@knu.ac.kr; | JOURNAL OF THORACIC DISEASE | J THORAC DIS | 2072-1439 | 2077-6624 | 15 | 7 | SCIE | RESPIRATORY SYSTEM | 2023 | 2.1 | 57.9 | 0.73 | 2025-06-25 | 5 | 5 | Bronchiectasis; hemoptysis; hospitalization; mortality | CYSTIC FIBROSIS BRONCHIECTASIS; COMMUNITY-ACQUIRED PNEUMONIA; ADULT PATIENTS; INTERNATIONAL DERIVATION; PROGNOSTIC-FACTORS; MORTALITY; SEVERITY; COHORT | Bronchiectasis; hemoptysis; hospitalization; mortality | anticoagulant agent; corticosteroid; hypertensive factor; adult; aged; anthracosis; arterial embolization; Article; bacterial colonization; bronchiectasis; clinical feature; comparative study; controlled study; disease association; disease exacerbation; ECOG Performance Status; emphysema; female; forced expiratory volume; hematological parameters; hemoptysis; hospital patient; hospitalization; human; hypertrophy; idiopathic disease; in-hospital mortality; Korea; length of stay; lung function test; lung tuberculosis; major clinical study; male; measles; middle aged; mortality rate; mycetoma; pertussis; phenotype; Pseudomonas aeruginosa; radiological parameters; respiratory tract infection; retrospective study; survivor; tertiary care center; treatment outcome; x-ray computed tomography | English | 2023 | 2023-07 | 10.21037/jtd-22-1541 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Indexing hs code- a hybrid indexer for an optimized search of geotagged data | In case of unstructured data processing current technologies have developed a lot of solutions to process and provide insight into it, which has become paramount today due to the permeation of social media. Social media analytics extract data points by searching the most relevant textual reference and isolating textual data with location information. This increase the complexity of modern social media search engines. The indexer is imperative towards the performance of these engines. Geotagged data generated via modern social media technologies has augmented the need to enhance such search mechanisms designed for spatial data.Conventional spatial indexers designed to handle such data can accurately search spatial objects but with a considerable increase in seek time. This paper presents a hybrid spatial indexer based on "Hs-I" tree for the "Social Media Spatial Analytical (SMSA)" model. The purposed indexer is 17.768% faster when compared with the "Geo-hash" indexer. The model refers "CBDFI" model for base architecture and deploys the advantage of the "hs" code. The paper presents the comparison of the purposed indexer with various other spatial indexers and highlights its key points in terms of execution time. | Singh, Bhagwant; Srivastava, Kingshuk; Gupta, D.

| ○ | ○ | Article | Paper name: geo-based recommendation system utilising geo tagging and K-means clustering | As technology advances, recommendation systems play an increasingly significant role in everyday life. Users today receive information efficiently and effectively through location-based recommender systems on their mobile devices. Geo-tagged data and the global positioning system are used to gather information about users in location-specific recommender systems. In this busy world, coffee is also a daily requirement. Therefore, we determine whether a particular population of individuals with mobile devices or other utility devices needs recommendations for coffee shops in a particular area. This was achieved by creating a Coffee Shop recommendation system, which uses geotagging to pinpoint the location dependent on latitude and longitude. In this article, we present a machine learning approach to assigning locations to coffee shops based on geo-based location suggestions. To determine the effectiveness of the coffee shop recommendation, a population-based zone-wise analysis was also conducted. | Shukla, Amar; Choudhury, Tanupriya; Benara, Nehit; Garg, Piyush; Tiwari, Aditya; Um, Jung-Sup | Univ Petr & Energy Studies UPES, Sch Comp Sci, Dehra Dun 248007, Uttarakhand, India; Kyungpook Natl Univ, Coll Social Sci, Dept Geog, 80 Univ Rd, Daegu 702701, South Korea | Tiwari, Aditya/JHS-6379-2023; Um, Jung-Sup/F-5351-2018; Choudhury, Tanupriya/AAB-8947-2020 | 57217089429; 57193140084; 57966856000; 57967369400; 59287058900; 35173565000 | amar28071989@gmail.com;tanupriya1986@gmail.com;210nehit@gmail.com;piyushgarguno@gmail.com;Tiwari.adityacool@gmail.com;jsaeom@knu.ac.kr; | SPATIAL INFORMATION RESEARCH | SPAT INF RES | 2366-3286 | 2366-3294 | 31 | 3 | ESCI | REMOTE SENSING | 2023 | 2 | 57.9 | 0.37 | 2025-06-25 | 3 | 3 | Recommendation system; Geo tagging; Machine learning; K-means; Mobile devices | Geo tagging; K-means; Machine learning; Mobile devices; Recommendation system | K-means clustering; Location; Machine learning; User interfaces; Coffee shops; Geo-tagging; Information research; K-means; K-means++ clustering; Location-based recommenders; Machine-learning; Spatial informations; Tagged data; Technology advances; cluster analysis; GPS; latitude; machine learning; mobile communication; population density; Recommender systems | English | 2023 | 2023-06 | 10.1007/s41324-022-00495-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Ultrasound-guided lung biopsy for small (?2 cm) subpleural lung lesions: comparison of diagnostic yield and safety with larger lesions | Background: Ultrasound (US)-guided percutaneous core needle biopsy (PCNB) have been used to diagnose subpleural lung lesions with high diagnostic performance and acceptable complication rates. However, with regard to the role of US-guided needle biopsy for the diagnosis of small (5 cm). The sample adequacy, diagnostic success rate, diagnostic accuracy, and complication rate was calculated. For statistical analysis, one-way ANOVA, Kruskal-Wallis test, or the chi- square test were used. Results: The overall sample adequacy, diagnostic success rate, and diagnostic accuracy were 96.2%, 82.9%, and 90.4%, respectively. In the subgroup analysis, sample adequacy (93.1% vs. 96.1% vs. 96.9%, P=0.307), diagnostic success rate (75.0% vs. 81.6% vs. 85.7%, P=0.079), and diagnostic accuracy (84.7% vs. 90.8% vs. 90.5%, P=0.301) were not significantly different. Operator's experience (OR, 0.64; 95% CI: 0.49-0.80; P<0.001), lesion size (OR, 0.68; 95% CI: 0.54-0.83; P<0.001), PCL (OR, 0.68; 95% CI: 0.52-0.84; P=0.001), and presence of air-bronchogram (OR, 14.36; 95% CI: 4.18-48.53; P<0.001) were independently associated with complication rate. Conclusions: US-guided PCNB performed by an experienced radiologist could be an effective and safe diagnostic approach for subpleural lesions, even in small lesions. | Park, Byunggeon; Park, Jongmin; Shin, Kyung Min; Lim, Jae-Kwang; Hong, Jihoon; Cha, Jung Guen; Lee, So Mi; Cho, Seung Hyun; Choi, Sun Ha; Jeong, Ji Yun; Do, Young Woo | Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Thorac & Cardiovasc Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, 680 Gukchaebosang Ro,Jung Gu, Daegu 41944, South Korea | skmrad@knu.ac.kr; | JOURNAL OF THORACIC DISEASE | J THORAC DIS | 2072-1439 | 2077-6624 | 15 | 5 | SCIE | RESPIRATORY SYSTEM | 2023 | 2.1 | 57.9 | 5 | Biopsy; ultrasound; complication | PERCUTANEOUS NEEDLE-BIOPSY; CANCER ACTION PROJECT; PERIPHERAL LUNG; RISK-FACTORS; PULMONARY-LESIONS; ASPIRATION BIOPSY; CT; PNEUMOTHORAX; US; NODULES | English | 2023 | 2023-05 | 10.21037/jtd-22-1546 | 바로가기 | 바로가기 | 바로가기 |
