| ○ | Book chapter | In Vivo Bioluminescent Imaging of Bone Marrow-Derived Mesenchymal Stem Cells in Mice | Mesenchymal stem cells (MSCs) are multipotent adult stem cells present in multiple tissues, such as bone marrow, adipose tissue, umbilical cord, and amniotic fluid. MSCs can differentiate into multilineage cells under defined conditions in vitro and in vivo. MSCs have been shown to have therapeutic effects on various types of diseases. Noninvasive in vivo monitoring of MSCs is considered one of the important techniques for developing cell therapy. In this protocol, we introduce strategized MSCs derived from bone marrow (BM-MSCs) of knock-in mouse model expressing mCherry-Renilla luciferase (mCherry-RLuc) for noninvasive bioluminescence imaging (BLI) of injected BM-MSCs in vivo. © 2022, The Author(s), under exclusive license to Springer Science+Business Media, LLC, part of Springer Nature. | Gangadaran, Prakash; Oh, Ji Min; Rajendran, Ramya Lakshmi; Ahn, Byeong-Cheol | BK21 FOUR KNU Convergence Educational Program of Biomedical Sciences for Creative Future Talents, Department of Biomedical Science, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; BK21 FOUR KNU Convergence Educational Program of Biomedical Sciences for Creative Future Talents, Department of Biomedical Science, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Nuclear Medicine, Kyungpook National University Hospital, Daegu, South Korea | 54393130400; 57190370462; 57195318729; 7202791511 | abc2000@knu.ac.kr; | Methods in Molecular Biology | 1064-3745 | 2525 | 0.32 | 2025-06-25 | 1 | Bioluminescence (BL); Bone marrow stem cells; In vivo imaging; Renilla luciferase (RLuc) | Animals; Bone Marrow; Bone Marrow Cells; Cell Differentiation; Cell Proliferation; Mesenchymal Stem Cells; Mice; Renilla luciferin 2 monooxygenase; animal care; animal cell; animal experiment; bioluminescence; bone marrow mesenchymal stem cell; cervical spine dislocation; controlled study; forelimb; humerus; in vivo study; inguinal region; male; mouse; nonhuman; pH; phase contrast microscopy; animal; bone marrow; bone marrow cell; cell differentiation; cell proliferation; mesenchymal stem cell | English | Final | 2022 | 10.1007/978-1-0716-2473-9_21 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Inadvertent accident during balloon-occluded glue injection for facial AVM: rescue procedure using intentional glue injection | Background Glue embolization during balloon inflation is a novel technique with many advantages. However, the procedure's major complication is the adhesion of the balloon catheter by glue. Several studies have reported strategies to prevent this. However, no reports have described a rescue method after accidental adhesion occurs. Case presentation A 26-year-old male was referred to the department of interventional radiology for sclerotherapy of an aggravating large facial arteriovenous malformation (AVM). We planned a transvenous approach to decrease the velocity of AVM and increase the efficacy of the sclerotherapy treatment. We performed glue embolization of a major draining vein during microballoon inflation. Upon injection of the glue, inadvertent glue reflux occurred, and the microballoon was stuck to the vessel wall. While removing the microballoon catheter, its shaft broke in the guiding catheter. We filled the inner lumen of the guiding catheter with glue and waited for polymerization to fixate the broken microballoon catheter inside the guiding catheter. Fortunately, the stuck microballoon was separated, and two broken pieces of microballoon catheter were removed through femoral vein short sheath. Conclusion Intentional glue casting in the outer catheter is very useful when removing anything that is inside the catheter or stuck due to the glue reflux. It can be applied to various similar emergency situations. | Hong, Jihoon; Cha, Jung Guen | Kyungpook Natl Univ, Dept Radiol, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 57215858314; 57206855971 | ircha7527@gmail.com; | CVIR ENDOVASCULAR | CVIR ENDOVASC | 2520-8934 | 5 | 1 | ESCI | CARDIAC & CARDIOVASCULAR SYSTEMS;PERIPHERAL VASCULAR DISEASE;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2022 | 1.2 | 0 | 2025-06-25 | 0 | 0 | Arteriovenous malformation; Balloon-occluded glue injection; Glue adhesion | EMBOLIZATION; BODY | Arteriovenous malformation; Balloon-occluded glue injection; Glue adhesion | anesthetic agent; iodinated poppyseed oil; sclerosing agent; surgical glue; adult; arteriovenous malformation; artery puncture; Article; artificial embolization; balloon occlusion; blood vessel wall; carotid arteriography; case report; clinical article; computed tomographic angiography; drug efficacy; external carotid artery; face malformation; femoral vein; fluoroscopy; general anesthesia; human; injection; interventional radiology; male; polymerization; sclerotherapy | English | 2022 | 2022-03-01 | 10.1186/s42155-022-00290-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Review | Incorporation of real-world data to a clinical trial: use of external controls | As real-world data (RWD) becomes more available and the methodology for handling RWD evolves, the use of RWD in drug development and drug approval is drawing interest. One of the ways RWD can be applied to a clinical trial is using an external control, a cohort of patients established separately serving as a control group for the clinical trial's treatment group. Although external controls have the possibility of bias as a result of differences in baseline characteristics between the external control and experimental groups, selecting an appropriate data source and ensuring comparability through proper handling of the data can increase the utility of external controls, raising the efficiency of drug development. This article discusses several topics relevant to using external controls in clinical trials, including the definition of external control, the selection of data sources, the strategy ensuring comparability, current regulatory circumstances, and future directions. | Kim, Tae-Eun; Park, Sang-In; Shin, Kwang-Hee | Konkuk Univ, Dept Clin Pharmacol, Med Ctr, Seoul 05030, South Korea; Kangwon Natl Univ, Coll Med, Dept Pharmacol, Chunchon 24341, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Daegu 41566, South Korea; Konkuk Univ, Dept Clin Pharmacol, Med Ctr, 120-1 Neungdong, Seoul, South Korea | ; Kim, Tae/I-6368-2018; Park, Sang-in/NJR-1727-2025 | 7407122618; 56505728500; 35216279300 | tekim@kuh.ac.kr; | TRANSLATIONAL AND CLINICAL PHARMACOLOGY | TRANSL CLIN PHARMACO | 2289-0882 | 2383-5427 | 30 | 3 | ESCI | PHARMACOLOGY & PHARMACY | 2022 | 0.9 | 0.24 | 2025-06-25 | 3 | 4 | External Control; Real-World Data; Clinical Trial | Clinical Trial; External Control; Real-World Data | blinatumomab; cerliponase alfa; acute lymphoblastic leukemia; cancer prognosis; cancer registry; clinical outcome; clinical practice; clinical research; Concurrent control; degenerative disease; drawing; drug approval; external control; follow up; genotype; human; medical practice; methodology; neuronal ceroid lipofuscinosis; overall survival; Philadelphia 1 chromosome; pre B lymphocyte; probability; propensity score; prospective study; randomized controlled trial (topic); rating scale; real world data; remission; Review; sensitivity analysis; spectrum; treatment response; United States | English | 2022 | 2022-09 | 10.12793/tcp.2022.30.e14 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Increase in blood glucose level and incidence of diabetic ketoacidosis in children with type 1 diabetes mellitus in the Daegu-Gyeongbuk area during the coronavirus disease 2019 (COVID-19) pandemic: a retrospective cross-sectional study | Background: The coronavirus disease 2019 (COVID-19) outbreak in the Daegu-Gyeongbuk area in 2020 has caused difficulties in the daily life and hospital care of children with type 1 diabetes mellitus (T1DM). We detected an increase in blood sugar levels in these children and the number of patients hospitalized with more severe diabetic ketoacidosis (DKA) compared to those before COVID-19. Methods: This single-center study was conducted at Kyungpook National University Children's Hospital. The following patient groups were included; 45 returning patients diagnosed with T1DM and undergoing insulin treatment for more than 2 years and 20 patients newly diagnosed with T1DM before and after COVID-19 were selected by age matching. Returning patients before and after the out-break were selected, and changes in hemoglobin A1c (HbA1c) levels were retrospectively reviewed. The HbA1c levels and severity of symptoms in newly diagnosed patients during hospitalization were examined. Results: HbA1c levels in returning patients with T1DM were significantly increased after COVID-19 (before, 7.70%+/- 1.38% vs. after, 8.30%+/- 2.05%; p=0.012). There were 10 and 10 newly diagnosed patients before and after COVID-19, respectively. The proportion of patients with drowsiness and dyspnea at the time of admission was higher after COVID-19 than before (before, 2 of 10 vs. after, 4 of 10). The HbA1c levels were higher in newly diagnosed patients hospitalized after COVID-19 than before (before, 11.15% vs. after, 13.60%; p= 0.036).Conclusion: Due to COVID-19 in the Daegu-Gyeongbuk area, there was an increase in blood glucose levels in children with T1DM and in the incidence of severe DKA in newly diagnosed diabetes mellitus patients. | Lee, Mi Seon; Lee, Rosie; Ko, Cheol Woo; Moon, Jung Eun | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Pediat, 807 Hoguk Ro, Daegu 41404, South Korea | 57209284335; 58740218800; 7202596445; 57205770947 | subuya@daum.net; | JOURNAL OF YEUNGNAM MEDICAL SCIENCE | 2799-8010 | 39 | 1 | 0.92 | 2025-06-25 | 10 | 13 | COVID-19; Diabetic ketoacidosis; Type 1 diabetes mellitus | GLYCEMIC CONTROL; CLINICAL CHARACTERISTICS; EARTHQUAKE; INFECTION; LOCKDOWN; QUALITY; IMPACT; YOUTH | COVID-19; Diabetic ketoacidosis; Type 1 diabetes mellitus | English | 2022 | 2022 | 10.12701/yujm.2021.01221 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Increased interleukin-6 and TP53 levels in rotator cuff tendon repair patients with hypercholesterolemia | Background: A previous study reported that hyperlipidemia increases the incidence of tears in the rotator cuff tendon and affects healing after repair. The aim of our study was to compare the gene and protein expression of torn rotator cuff tendons in patients both with and without hypercholesterolemia. Methods: Thirty patients who provided rotator cuff tendon samples were classified into either a non-hypercholesterolemia group (n=19, serum total cholesterol [TC] <200 mg/dL) and hypercholesterolemia group (n=11, serum TC =240 mg/dL) based on their concentrations of serum TC. The expression of various genes of interest, including COL1A1, IGF1, IL-6, MMP2, MMP3, MMP9, MMP13, TNMD, and TP53, was analyzed by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). In addition, Western blot analysis was performed on the proteins encoded by interleukin (IL)-6 and TP53 that showed significantly different expression levels in real-time qRT-PCR. Results: Except for IGF1, the gene expression levels of IL-6, MMP2, MMP9, and TP53 were significantly higher in the hypercholesterolemic group than in the non-hypercholesterolemia group. Western blot analysis confirmed significantly higher protein levels of IL-6 and TP53 in the hypercholesterolemic group (p<0.05). Conclusions: We observed an increase in inflammatory cytokine and matrix metalloproteinase (MMP) levels in hypercholesterolemic patients with rotator cuff tears. Increased levels of IL-6 and TP53 were observed at both the mRNA and protein levels. We suggest that the overexpression of IL-6 and TP53 may be a specific feature in rotator cuff disease patients with hypercholesterolemia. | Yoon, Jong Pil; Min, Seung Gi; Choi, Jin-Hyun; Lee, Hyun Joo; Park, Kyeong Hyeon; Yoon, Sung Hyuk; Kim, Seong Soo; Chung, Seok Won; Kim, Hun-Min; Kim, Dong Hyun | Kyungpook Natl Univ, Sch Med, Dept Orthopaed Surg, Daegu, South Korea; Kyungpook Natl Univ, Dept Biofibers & Mat Sci, Daegu, South Korea; Konkuk Univ, Dept Orthopaed Surg, Sch Med, Seoul, South Korea; Korea Dyeing & Finishing Technol Inst DYETEC, Daegu, South Korea | Park, KyeongHyeon/KEH-4919-2024; Kim, Sooyeon/AAA-8521-2022; Lee, Hyun Joo/GVU-6347-2022; Kim, Sae/AAR-3907-2020 | oskdh87090@gmail.com; | CLINICS IN SHOULDER AND ELBOW | 2288-8721 | 25 | 4 | 4 | Inflammation; Interleukin; Hypercholesterolemia; Rotator cuff | EXTRACELLULAR-MATRIX; FATTY INFILTRATION; COLLAGEN-SYNTHESIS; P53; SIMVASTATIN; EXPRESSION; APOPTOSIS; MUSCLE; MODEL; TEAR | English | 2022 | 2022-12 | 10.5397/cise.2022.00976 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Article | Infection prevention measures and outcomes for surgical patients during a COVID-19 outbreak in a tertiary hospital in Daegu, South Korea: a retrospective observational study | Background: The first large coronavirus disease 2019 (COVID-19) outbreak outside China occurred in Daegu. In response, we developed infection prevention measures for surgical patients during the outbreak at our hospital and retrospectively reviewed the out-comes of COVID-19-related surgical patients.Methods: We reviewed the medical records of 118 COVID-19-related surgical patients and monitored their clinical outcomes until March 31, 2021. We also interviewed healthcare workers who participated in their perioperative care at Kyungpook National University Chilgok Hospital. The perioperative management guidelines for COVID-19-related patients were prepared through multidisciplinary discussions, including the infection control department, surgical departments, and anesthesiology department before and during the COVID-19 outbreak.Results: One standard operating room was temporarily converted to a negative-pressure room by increasing the exhaust air volume, creating a relative pressure of -11.3 Pa. The healthcare workers were equipped with personal protective equipment according to the patient's classification of the risk of COVID-19 transmission. The 118 COVID-19-related patients underwent emergent surgery in the negative-pressure room, including three COVID-19-confirmed patients and five COVID-19-exposed patients.Conclusion: All surgeries of the COVID-19-related patients were performed without specific adverse events or perioperative COVID-19 transmission. Our experience setting up a negative-pressure operating room and conservative perioperative protocol to prevent COVID-19 transmission will help plan and execute infection control measures in the future. | Kwak, Kyung-Hwa; Kim, Jay Kyoung; Kwon, Ki Tae; Yeo, Jinseok | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Anesthesiol & Pain Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea | ; Kim, Hanjin/KYP-2633-2024 | 22937974700; 57218347150; 9733850500; 35072322000 | jsyeo@knu.ac.kr; | JOURNAL OF YEUNGNAM MEDICAL SCIENCE | 2799-8010 | 39 | 3 | 0 | 2025-06-25 | 0 | 0 | COVID-19; Infection; Prevention; Surgery | SARS-COV-2 | COVID–19; Infection; Prevention; Surgery | English | 2022 | 2022 | 10.12701/yujm.2021.01431 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Proceedings Paper | Inference of Vehicle Lane Change Intention Using Multiple Model Estimator in Automated Highway Driving | One of the most critical topics in vehicle active safety control is collision avoidance(CA) maneuver. To ensure the robustness of the CA, it is essential to recognize the behavior of surrounding vehicles accurately. In particular, a safer path can be generated, if the intention of changing lanes of surrounding vehicles can be predicted. Existing studies on lane change intention prediction are primarily based on machine learning, and it is difficult to respond to unexpected situations that have not been learned. In this study, a method for predicting lane change intention in real time based on the trajectory of surrounding vehicles is presented. It is assumed that the location of the lane is known through the map, and the global coordinate system is transformed into the Frenet coordinate system to maintain generality regardless of the curvature of the road. And the paths that the target vehicle can travel are modeled as cubic spline curves on the Frenet coordinate system. Through the multiple model estimator, which operates the path models in parallel, it finds the most probable path and predicts the lane change intention. The performance of the lane change intention prediction algorithm is verified through highD, a German highway vehicle trajectories dataset. | Do, Jongyong; Han, Kyoungseok; Choi, Seibum B. | Korea Adv Inst Sci & Technol, Dept Mech Engn, Daejeon 34141, South Korea; Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | djy0129@kaist.ac.kr;kyoungsh@knu.ac.kr;sbchoi@kaist.ac.kr; | 2022 22ND INTERNATIONAL CONFERENCE ON CONTROL, AUTOMATION AND SYSTEMS (ICCAS 2022) | 2093-7121 | 2 | Lane-change intention; Multiple model estimator; Unscented Kalman filter; Cubic spline; Frenet coordinates | English | 2022 | 2022 | 바로가기 | |||||||||||||||||||||||

| ○ | ○ | Article | Influence of Chewing Ability on Elderly Adults' Cognitive Functioning: The Mediating Effects of the Ability to Perform Daily Life Activities and Nutritional Status | Chewing ability is also related to activities of daily living (ADLs) and nutritional status; however, these associations have not been firmly established. We examined chewing ability as a predictor variable and explored its relationship with cognitive functioning as mediated by ADLs and nutritional status data were collected by face-to-face interviews. Patients were receiving home healthcare service in Mun-gyeong city, Gyung-buk, Korea. Participants comprised 295 patients aged 81.35 +/- 6.70 years. Structural equation modeling (SEM) was performed using AMOS 18.0 (SPSS Inc., Chicago, IL, USA). The model fit was based on absolute fit index and incremental fit index. Data were collected to assess cognitive functioning (using the Korean version of the Mini-Mental Status Examination for dementia screening (MMSE-DS)), ADL, a mini-nutritional assessment (MNA) questionnaire, and a chewing ability test. Participants with better chewing ability had significantly better cognitive functioning, ADLs, and nutritional status (p < 0.001). Chewing ability directly affected cognitive functioning and indirectly affected how ADLs and MNA affected MMSE-DS. Chewing ability is an important factor influencing the cognitive functioning of elderly adults in Korea, both directly and indirectly through mediating variables such as nutritional status and ADLs. Efforts to help older adults maintain their chewing ability are necessary for preventing cognitive impairment. | Jung, Yun-Sook; Park, Taejun; Kim, Eun-Kyong; Jeong, Seong-Hwa; Lee, Young-Eun; Cho, Min-Jeong; Song, Keun-Bae; Choi, Youn-Hee | Kyungpook Natl Univ, Dept Dent Hyg, Coll Sci & Technol, 2559 Gyeongsang Daero, Sangju Si 37224, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Prevent Dent, Sch Dent, Daegu 41940, South Korea; Daegu Haany Univ, Fac Hlth Sci, 1 Hanuidae Ro, Gyongsan 38610, Gyeongsangbuk D, South Korea; Daegu Hlth Coll, Dept Dent Hyg, 15 Yeongsong Ro, Daegu 41453, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu 41940, South Korea | ; LEE, YOUNG-EUN/HDO-1938-2022 | 57193342858; 57221686957; 55915892100; 14519286200; 36120703200; 57201842940; 35105905200; 7404777239 | ysjung0313@gmail.com;parktj@gmail.com;jinha01@naver.com;jeongsh@dhu.ac.kr;yelee@dhc.ac.kr;beijingjo72@hanmail.net;kbsong@knu.ac.kr;cyh1001@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 3 | 1.08 | 2025-06-25 | 10 | 12 | chewing ability; cognitive functioning; structural equation modeling | MINI-MENTAL STATE; ALZHEIMERS-DISEASE; TOOTH LOSS; INSTRUMENTAL ACTIVITIES; ORAL-HEALTH; RISK-FACTOR; DEMENTIA; MASTICATION; ASSOCIATION; IMPAIRMENT | Chewing ability; Cognitive functioning; Structural equation modeling | Activities of Daily Living; Aged; Aged, 80 and over; Cognition; Cognitive Dysfunction; Humans; Mastication; Nutritional Status; Korea; cognition; elderly population; physical activity; public health; aged; Article; cognition; cognition assessment; daily life activity; discriminant validity; female; home care; human; interview; Korea; major clinical study; male; mastication; Mini Mental State Examination; nutritional assessment; nutritional status; population research; questionnaire; scoring system; structural equation modeling; very elderly; cognition; cognitive defect; mastication; nutritional status | English | 2022 | 2022-02 | 10.3390/ijerph19031236 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | INFLUENCE OF TIRE CONTACT AREA ON THE TRACTION PERFORMANCE OF A 67-KW AGRICULTURAL TRACTOR IN A PADDY FIELD | Agricultural tractors operate on soil, and power loss occurs due to the complex interaction between tractor tires and soil. There are various methods for minimizing the loss of power and driving the tractor efficiently, one of which is increasing the tire contact area (TCA). The aim of this study is to measure, evaluate, and optimize the traction perfor-mance of a tractor with different TCAs. A traction load measurement system of the tractor was developed to measure field data. Field experiments were conducted to measure the traction performance of the tractors on paddy fields. To improve the traction performance of the tractor, the TCA was increased through various tire combinations, and a total of four TCA conditions were used. The results showed that the slip ratio of the wheel decreased with increasing TCA, thereby reducing the power loss due to the soil and increasing the traction performance, including the traction force, traction power, tractive efficiency, and dynamic traction ratio. Therefore, it is possible to improve the performance of tractors in paddy fields through TCA adjustment, and this study can provide appropriate guidelines. | Kim, Wan -Soo; Kim, Yong-Joo; Lee, Nam-Gyu; Baek, Seung-Min; Baek, Seung-Yun; Kim, Yeon-Soo | Kyungpook Natl Univ, Dept Bioind Machinery Engn, Daegu, South Korea; Chungnam Natl Univ, Dept Biosyst Machinery Engn, Daejeon, South Korea; Chungnam Natl Univ, Dept Smart Agr Syst, Daejeon, South Korea; Korea Construct Equipment Technol Inst, Mat & Component Convergence Ctr, Gunsan, South Korea; Korea Inst Ind Technol KITECH, Smart Agr Machinery R&D Grp, Gimje, South Korea | Kim, Yong-Joo/AAK-1840-2021 | 57192918810; 57204759454; 57204039579; 57204040500; 57216612175; 57192923355 | babina@cnu.ac.kr; | JOURNAL OF THE ASABE | J ASABE | 2769-3295 | 2769-3287 | 65 | 6 | SCIE | AGRICULTURAL ENGINEERING | 2022 | N/A | 0.31 | 2025-06-25 | 2 | 3 | Agricultural tractor; Dynamic traction ratio; Tire contact area; Traction performance; Tractive efficiency | PREDICTION; SOIL | Agricultural tractor; Dynamic traction ratio; Tire contact area; Traction performance; Tractive efficiency | Agriculture; Efficiency; Soils; Tires; Contact areas; Dynamic traction ratio; Paddy fields; Power; Powerloss; Soil loss; Tire contact; Tire contact area; Traction performance; Tractive efficiency; efficiency measurement; instrumentation; measurement method; paddy field; performance assessment; Tractors (agricultural) | English | 2022 | 2022 | 10.13031/ja.15008 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

Multidimensional measures of informed choice regarding NIPT and decisional conflict were used to measure participants' levels of knowledge, attitudes, deliberation, uptake, and decisional conflict related to NIPT. Additional questions were asked about participants' NIPT experiences and opinions. Results: All 129 pregnant women were recruited from an online community. Excluding those who expressed neutral attitudes toward NIPT, according to the definition of informed choice used in this study, only 91 made an informed choice (n=63, 69.2%) or an uninformed choice (n=28, 30.8%). Of the latter, 75.0% had insufficient knowledge, 39.3% made a value-inconsistent decision, and 14.3% did not deliberate sufficiently. No difference in decisional conflict was found between the two groups. A significant difference was found between the two groups in the reasons why NIPT was introduced or recommended (p=.021). Multiple logistic regression analysis showed that pregnant women who were knowledgeable (odds ratio [OR], 4.77; 95% confidence interval [CI], 2.17-10.47) and deliberated (OR, 0.74; 95% CI, 0.57-0.98) were significantly more likely to make an informed choice. Conclusion: The results of this study help healthcare providers, including nurses in maternity units, understand pregnant women's experiences of NIPT. Counseling strategies are needed to improve pregnant women's knowledge of NIPT and create an environment that promotes deliberation regarding this decision. | Choi, Hyunkyung | Kyungpook Natl Univ, Coll Nursing, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Res Inst Nursing Sci, Daegu, South Korea | 55619940700 | hchoi@knu.ac.kr; | KOREAN JOURNAL OF WOMEN HEALTH NURSING | KOREAN J WOMEN HEALT | 2287-1640 | 2093-7695 | 28 | 3 | ESCI | NURSING | 2022 | 0.6 | 0.5 | 2025-06-25 | 3 | 3 | Cell-free DNA; Conflict; psychological; Counseling; Decision making; Prenatal care | DOWN-SYNDROME; DECISION AID; NIPT; ATTITUDES; IMPLEMENTATION; WANT; PART | Cell-free DNA; Conflict; Counseling; Decision making; Prenatal care; psychological | English | 2022 | 2022-09 | 10.4069/kjwhn.2022.09.10 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Proceedings Paper | Infrastructure-Independent Pseudonym Swap Protocol for Vehicular Networks | Vehicular Ad-hoc Networks (VANETs) are increasingly gaining the attention of academic institutions, governments, and automobile manufacturers due to their prospect to offer safety, traffic efficiency, and infotainment services to drivers and passengers. However, they suffer from location privacy leakage as vehicles must periodically transmit unencrypted beacon messages. One of the techniques proposed to preserve location privacy in the literature is pseudonym swap. However, existing pseudonym swap schemes either depend on Roadside Units (RSUs) or ignore VANET security requirements. Therefore, we propose a new pseudonym swap scheme that addresses the existing issues by using non-swappable and swappable pseudonyms. Moreover, vehicles simultaneously and randomly change pseudonyms soon after swapping, an approach that further enhances privacy in our scheme. The simulation experiments show that our scheme performs better in confusing a tracking adversary than the existing schemes. | Mdee, Abdueli Paulo; Khan, Muhammad Toaha Raza; Seo, Junho; Kim, Dongkyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | Khan, Turyalai/HPH-0061-2023 | 57766373000; 59158639500; 57208740581; 35753648800 | apmdee@knu.ac.kr;toaha@knu.ac.kr;jhseo@knu.ac.kr;dongkyun@knu.ac.kr; | 2022 THIRTEENTH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS (ICUFN) | 2165-8528 | 2165-8536 | 0.51 | 2025-06-25 | 2 | 2 | Vehicular Ad-hoc Networks (VANETs); Location Privacy; Non-swappable and Swappable Pseudonyms; RSU independence | LOCATION PRIVACY; SCHEME | Location Privacy; Non-swappable and Swappable Pseudonyms; RSU independence; Vehicular Ad-hoc Networks (VANETs) | Location; Academic institutions; Automobile manufacturers; Location privacy; Non-swappable and swappable pseudonym; Roadside unit independence; Roadside units; Traffic efficiency; Vehicular ad-hoc network; Vehicular Adhoc Networks (VANETs); Vehicular networks; Vehicular ad hoc networks | English | 2022 | 2022 | 10.1109/icufn55119.2022.9829588 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Inhibitory Effects of Dietary Schisandra Supplements on CYP3A Activity in Human Liver Microsomes | : Schisandra chinensis and its fruits have been used as a traditional herbal medicine to treat liver dysfunction, fatigue, and chronic coughs. Several in vitro and in vivo studies suggested that dibenzocyclooctadiene lignans present in Schisandra fruits strongly inhibit CYP3A4 activity. However, reports on the inhibitory potential of dietary Schisandra supplements against CYP3A activity are limited despite their increasing consumption as dietary supplements. In this study, we evaluated the CYP3Ainhibitory potential of four dietary Schisandra supplements in human liver microsomes. At a concentration of 0.05 mg/mL, Schisandra supplements from Nature's Way, Swanson, Planetary Herbals, and Only Natural inhibited CYP3A activity by 93.9, 70.8, 33.6, and 24.8%, respectively. Nature's Way, which exhibited the strongest inhibition against CYP3A, had the highest contents of gomisin B and gomisin C, which potently inhibit CYP3A activity. The in vivo pharmacokinetics of this product should be examined to determine whether the clinical relevance of inhibiting CYP3A activity by dietary Schisandra supplementation. | Kang, Bae-Gon; Park, Eun-Ji; Park, So -Young; Liu, Kwang-Hyeon | Kyungpook Natl Univ, Coll Pharm, BK21 FOUR Community Based Intelligent Novel Drug D, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea | 58068275800; 57203611956; 57211630074; 55768214700 | dstlkh@knu.ac.kr; | MASS SPECTROMETRY LETTERS | MASS SPECTROM LETT | 2233-4203 | 2093-8950 | 13 | 4 | ESCI | SPECTROSCOPY | 2022 | 0.5 | 0.08 | 2025-06-25 | 1 | 1 | Keywords; CYP3A; Inhibition; Lignan; Schisandra supplements | HERB-DRUG INTERACTIONS; SPHENANTHERA-EXTRACT; PHARMACOKINETICS | CYP3A; Inhibition; Lignan; Schisandra supplements | English | 2022 | 2022-12 | 10.5478/msl.2022.13.4.152 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Conference paper | Input-Parallel Output-Parallel Current-Fed Isolated DC-DC Converters with Double Step-Down Converter | This paper shows an effective current balancing technique of the input-parallel output-parallel (IPOP) current-fed (CF) isolated dc-dc converters using a double step-down (DSD) converter. Inhering the benefit of the DSD converter, the currents of each CF isolated dc-dc module can be automatically well-balanced regardless of the mismatch in the gate signals and the different characteristics of active and passive components in use. The simulation and experimental results are provided and assessed to illustrate the advantages of the proposed converter. Furthermore, the explanation and discussion on the obtained results are concisely presented. © 2022 IEEE. | Nguyen, The-Tien; Thao, Nguyen Gia Minh; Cha, Honnyong; Bui, Van-Dai; Nguyen, Chan-Viet | Kyungpook National University, School of Energy Enginerring, Daegu city, South Korea; Toyota Technological Institute, Graduate School of Engineering, Nagoya city, Japan; Kyungpook National University, School of Energy Enginerring, Daegu city, South Korea; Kyungpook National University, School of Energy Enginerring, Daegu city, South Korea; Kyungpook National University, School of Energy Enginerring, Daegu city, South Korea | 59454647000; 55903864900; 24450248400; 57221961296; 57210827612 | nguyen.thao@toyota-ti.ac.jp; | ICCE 2022 - 2022 IEEE 9th International Conference on Communications and Electronics | 1.88 | 2025-06-25 | 6 | Buck-boost; current balancing; current-fed dc-dc converters; input-parallel output-parallel; isolated converters | Boost converter; Buck-boost; Current balancing; Current fed; Current-feed dc-dc converter; Dc/dc converters; Double-step; Input-parallel output-parallel; Isolated converters; Parallel output; Step-down converter; Buck-Boost converter | English | Final | 2022 | 10.1109/icce55644.2022.9852076 | 바로가기 | 바로가기 |
