Navier-Stokes식, Gaussian 분포형 용출함수를 이용한 내부조파, energy absorbing layer로 삼차원 파랑모형을 새롭게 구성하였다. Navier-Stokes식의 수치적분에는 정교한 수치기법인 SPH(Smoothed Particle Hydrodynamics)가 활용된다. 제안된 파랑모형의 검증은 삼차원 포물형 용기에서의 sloshing현상과 Thacker(1981)의 해석해를 토대로 수행되었다. 초기 수면 형상이 Gaussian hump인 경우와 일방향으로 경사진 경우에 대해 수치모의 하였다. 수치모의 결과 수면이 융기되도록 구속한 외부조건이 해제되면서 시작되는 자유진동의 정성적 거동은 비교적 정확히 모의되었으나 시간이 경과될수록 위상차, 침수선이 퇴각하는 등 초기 수면과는 상당히 다른 결과를 보였다. 최종적인 검증은 쐐기모양 해안에서의 비선형 천수, 굴절거동의 수치모의를 토대로 진행되었다. 수치모의 결과 굴절되는 양이 Hamiltonian ray theory가 제공하는 수치보다 전반적으로 작게 나타났다. 이러한 현상은 이상유체와 선형 이론에 기초한 Hamiltonian ray theory에서 간과된 비선형성, 점성으로 인한 양안과 저면에서의 에너지 감쇄, 쇄파 과정에 유동계에 도입되는 에너지 감쇄, 선행파랑에 의한 down-rush와 조우시 발생하는 도수 등에 기인하는 것으로 판단된다.

Background: Patients with chronic myeloid leukemia(CML) have different health status according to their disease conditions such as chronic phase(CP), accelerated phase(AP), blast crisis(BC), stage with MCyR(Major Cytogenetic Response); therefore, every patient has different quality of life related to their disease condition. Objectives: To measure the quality of life, this study compared and analyzed the utility weight in patients with CML. This study also evaluated the utility weight in order to view comparisons between the quality of life in a patient with CML to a patient with diabetes, which is a representative chronic disease. Methods: The disease scenario described 5 symptoms of the CP, AP, BC of the CML, the CML which gets the MCyR and the diabetes. Utility weight was developed using the EQ-5D method. All statistical data were analyzed by STATA 10.0 Results: 57 nurses(95%) out of 60 answered the questionnaire. In CP, the utility weight was 0.7946. In AP, it was 0.5301. and in BC, it was -0.2793. Survey data indicate that the worse the condition of a disease, the lower the utility weight. In case of the CML which gets the MCyR, the result was 0.7731(95% CI : 0.7384 - 0.8079). The general diabetes which has no complicating disease, the utility weight was 0.7481(95% CI : 0.6983 - 0.7978). Based on the result, it is evident that those with MCyR are not significantly different from people with general diabetes (p=0.4096) in views of the quality of life.

Depression is a major health problem that can lead to mortality. This study was conducted to assess the risk factors associated with depression in a group aged over 65 years by analyzing nationally representative Korean survey data. A total of 1,209 subjects were analyzed among the participants of the 2014 Korean National Health and Nutrition Examination Survey. Statistical methods for a complex sample were applied by using SPSS program(windows ver. 24.0). Depression assessments were carried out by using the 9-item depression module of the Patient Health Questionnaire-9 (PHQ-9). Depression ($PHQ-9{\geq}5$) was more frequently found in females (33.2%) compared to males (16.1%). However, there was no evidence suggesting that characteristics such as residence area, income level and age, except for educational level, were related with depression. The results of the logistic regression analysis showed that i) health habits such as smoking (OR: 2.26) and lack of aerobic physical activity (OR: 1.62), ii) mental health status such as bad self-rating of health status (OR: 4.30), more stress (OR: 8.31), and bad health-related quality of life (by EQ_5D, OR: 3.41), iii) chronic diseases such as obesity (OR: 0.66), hypercholesterolemia (OR: 1.57), anemia (OR: 1.91), and iv) low intake of energy (OR: 1.84) and calcium (OR: 1.71) were significantly associated with depression. This study suggests that certain characteristics of health habits, mental health status, chronic diseases and nutrient intake may be associated with depression. Prospective research on long-term control is needed to establish causal connections among those factors with depression.

Purpose: This study examined health determinants at a community level and put forward to a typology of five different forms of community health vulnerabilities. We also investigated the differences in the prevalence of chronic diseases, self-rated health, and quality of life (EQ-5D) among the five types. Methods: Latent class analysis was applied to material, social capital, and health behavior vulnerability variables across 255 regions of South Korea. The data came from 2017 & 2019 Community Health Survey. Results: We found five types of community health vulnerabilities: Type 1 group had the highest material vulnerabilities compared to Type 5. The typology was found to be significant in all the regression analysis on the prevalence of chronic diseases (hypertension and diabetes), self-rated health status, and quality of life. In the regions with high material vulnerabilities, the material vulnerability appeared the most effective to the health status of individual's. In the other regions with less material vulnerabilities, the social capital and health behavior resources were found to be effective. Conclusion: A comprehensive measure of vulnerability can be helpful to understand community health. Policy makers need to consider the level of material vulnerability when planning for a health promotion project.

Objectives: The purpose of this study was to examine the effects of oral and mental health status on temporomandibular joint disorders (TMDs) and the effects of TMD symptoms on quality of life using data from the 5th 2012 National Health and Nutrition Examination Survey. Methods: A total of 1,154 people were selected as subjects for the study. Temporomandibular joint (TMJ) sounds (672 persons), TMJ pain (227 persons), and TMJ dislocation (255 persons) were the factors studied. The complex sample chi-square test was performed to compare demographic characteristics according to the three groups of TMD symptoms. Complex sample logistic regression analysis was performed to confirm the effect of oral and mental health status on TMDs, and complex sample linear regression analysis was performed to check the effect of TMDs on the quality of life (EQ-5D). Results: After adjusting for demographic characteristics, those without TMJ sound symptoms had lower pain/discomfort (OR: 0.055, CI: -0.095 to -0.016) and anxiety/depression (OR: 0.053, CI: -0.092 to -0.014). Those without TMJ pain had lower pain/discomfort (OR: 0.119, CI: -0.192 to -0.046) and anxiety/depression (OR: 0.071, CI: -0.137 to -0.004). Pain/discomfort (OR: 0.063, CI: -0.125 to -0.001) was lower in those without TMJ dislocation symptoms. After adjusting for mental health status, pain/discomfort (OR: 0.088, CI: -0.161 to -0.014) was found to be lower in those without TMJ pain symptoms (p<0.05). Conclusions: Based on the results of this study, the treatment of TMDs, oral health, and also mental health, is needed to improve the quality of life.

Objectives: Depression is a highly prevalent disease, and the market for antidepressant drugs continues to grow at a steady rate. Although current antidepressants are reported to be effective, because of their low remission rate and side effects, new antidepressants are needed. The use of Banhahubak-tang (BHT) to treat the symptoms of depression is supported by experimental evidence. The proposed study will evaluate the efficacy and safety of BHT in treating depression. Methods: A randomized, waitlist-controlled, parallel clinical trial will be conducted to assess the efficacy of BHT in depression. A total of 84 participants with depression will be randomized into the intervention group or waitlist-control group at a 1:1 ratio. Patients in the intervention group will be administered BHT three times a day for four weeks and followed up for four more weeks after therapy completion. Patients in the waitlist-control group will undergo the same intervention and follow-up after a four-week waiting period. The primary outcome is change in the Korean version of the Hamilton Depression Rating Scale (K-HDRS) scores for major depressive disorders after four weeks. The secondary outcomes include scores on the K-HDRS, Korean Symptom Check List 95 (KSCL-95), Insomnia Severity Index (ISI), State-Trait Anxiety Inventory-Korean version (STAI-K), State-Trait Anger Expression Inventory-Korean version (STAXI-K), and the Instrument on Pattern Identifications for Depression and EuroQol-5 Dimension (EQ-5D). Conclusions: This trial will provide high-quality clinical evidence of the efficacy and safety of BHT in the management of depression.

Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.
