        Animal-Assisted Intervention programs and interventions with students are becoming promising field in school and therapeutic settings. Following this trend, Animal-Assisted Intervention (AAI) program was designed to help students adopt more easily to school life and to encourage them to keep healthy relationships with others. Accordingly, the purpose of this study was to identify the effects of animal-assisted intervention (AAI) on the middle school students' sociability and depression. The participants in this study, 8 middle school students residing in Seoul who were interested in animals and agreed to the research attended this program. This study was conducted two times a week for 6 weeks (a total of 12 times) with one main researcher and three research assistants. The major research tool was the test of sociability and depression and the statistical test being used for this study was Wilcoxon's signed ranks. The results were as follows. First, the study showed the significant effects of animal-assisted intervention on sociability for middle school students. There were significant differences in many aspects such as reliability, autonomy, sociability and compliance. Second, significant reductions in anxiety and depression were found after the introduction of animal-assisted intervention for students. Students who participated this program experienced a reduction in depression and stress to some degree. Also, they began to form much more positive friendships and followed school rules as well. Based on the above results, it can be seen that animal-assisted intervention program significantly has the positive effects on the social adaptability and depression of the middle school students. Therefore, this animal-assisted intervention should be considered as a positive program for emotional and psychological support for middle school students.

        대학생 시기는 여러 가지로 첫 시작을 위한 중요한 준비 시기라 할 수 있겠다. 이 시기에 있어 감정적 부분은 개인적, 대인관계적, 가치관, 직업적 기초 뿐 아니라 사회적으로도 서로간의 영향을 줄 수 있겠다. 무엇보다 사회복지 서비스를 준비하는 대학생 스스로에 대한 성향과 생각들은 인성과 그 준비에 중요한 관점이라 할 수 있다. 대학생의 시 기는 독립적인 시기의 준비이자 스스로에 있어 여러 다양한 새로운 경험과 문제를 다루는 것을 알게 되는 시기로 이러한 부분에 있어 우울감은 대학생활과 사회적 기초가 되는 이 시기에 학교생활과 대인관계 그리고 일생의 발달과업의 시작인 다양한 사회적 관계의 순간들에 중요한 영향을 미칠 수 있다. 이에 대학생의 자기애성향과 우울 및 자기애 성향과 우울간의 관계를 살펴보았다. 그 결과 자기애성향은 우울에 영향을 미쳤으며, 성별에 따른 우울감 차이로는 정서적 우울, 인지적 우울, 동기적 우울에 있어 남학생보다 여학생이 더 높았다. 자기애성향과 우울간의 관계로는 서로간의 유의미하게 관계가 있는 것으로 나타났다. 즉, 자기애성향이 높을수록 우울 경향이 높았다. 자기애성향의 하위 요인들로는 자기중심성이 높을수록 정서적 우울이 높았고, 자기중심성이 강할수록 인지적 우울과 동기적 우울이 높았다. 이에 대학생들의 우울감에 대한 관심 및 대인관계와 학교 생활에 있어 어려움에 대한 보다 다양한 방법으로 다각적인 상담 및 소규모 프로그램들을 통해 현실적인 평가와 자존감 향상을 통한 다양한 상담 및 활동 프로그램이 필요하다고 할 수 있겠다.

        Chronic obstructive pulmonary disease (COPD) is associated with multiple comorbidities, including depression, which carries a higher risk of exacerbation and hospitalization in patients with stable COPD. A newly developed questionnaire, the COPD Assessment Test (CAT), was developed as an alternative to other complex, time-consuming tools for quantifying the symptom burden of COPD in routine practice. It is possible that the correlation between the CAT and depression scales could be useful for early evaluation and management of depression in COPD patients. Thus, we investigated the relationship between the CAT and depression as measured by the Patient Health Questionnaires-9 (PHQ-9). We performed a retrospective observational COPD cohort study. A total of 97 patients were enrolled. The Korean versions of the CAT and PHQ-9 were completed for stable patients. A correlation analysis was performed between the PHQ-9 and CAT scores. Significant depression among the groups based on the 2011 GOLD guidelines occurred only in class Gold B and D patients (40% and 60%, respectively). The frequency of depression was significantly higher in the group with higher CAT scores (20~29 versus ≥30; odds ratio: 5.67 versus 22.66). Significant association was observed between the PHQ-9 and CAT scores (r=0.545 and P<0.001). As a result, the PHQ-9 score was significantly higher in COPD patients with a higher CAT score. The CAT is a simple and valuable predictor of depression in COPD patients, and it should be frequently used to detect COPD patients with depression in clinical practice.

        This study was carried out to determine the depression symptoms and nutritional status of elderly females that ate congregate meals at lunch in rural Pocheon. The subjects were 18 elderly females aged over 65 (75.7±4.6 years) and information on smoking, subjective health status, depression symptoms and malnutrition risk were collected using a questionnaire administered with the help of trained research assistants. Measurements included mid-arm circumference and calf circumference. Food consumption for 3 days during breakfast and supper were determined by 24-hour recall and food consumption at lunch was determined as the difference between the amounts served and the plate waste. All data were compared between two age groups (≤ 75 and > 75). The subjects had the lowest nutrient adequacy ratio (NAR) for vitamin B6 (0.523), followed by calcium and niacin and the lowest index of nutrient quality (INQ) for calcium (0.738). The older elderly had significantly lower NAR for vitamin B1, vitamin B2, vitamin B6 and niacin as well as significantly lower mean adequacy ratio (MAR) compared to the young elderly. They also had significantly lower INQ for vitamin B1 and vitamin C and significantly thinner arm circumference (28.3 cm vs. 31.3 cm). They consumed more than 40% of their daily intake for each nutrient at lunch. Higher proportions of nutrient intake from lunch provided evidence of the importance of congregate meals, suggesting that the government and society should support congregate meals to improve nutritional status.

        Fall is one of the most intimidating health conditions in elders. Comprehensive assessment is necessary to understand the individual and environmental aspects of the falls such as balancing abilities, depression, and quality of life. The purpose of this study was to compare the balancing ability, depression, and quality of life between elderly fallers and elderly non-fallers. Thirty-two community-dwelling elders (fifteen males and seventeen females between 65 and 83 years old), who have experienced fall on walking during last twelve months, were involved in the elderly fallers group. And twenty-four males and twenty-two females between 65 and 83 years old of community-dwelling elders, who have no experienced fall on walking during last twelve months, were involved in the elderly non-fallers group. Berg balance scale (BBS), timed up and go test (TUG), and functional reach test (FRT), were used to evaluate the ability of the physical balance. ‘Beck depression scale in Korean’ questionnaire was used to assess the depression. ‘Korean version of World Health Organization Quality of Life Assessment Instrument-Bref’ questionnaire was used to assess the quality of life. The results were as follows: 1) Balancing abilities measured by the BBS, TUG in the elderly fallers group were meaningfully lower than that of the elderly non-fallers group (p<.05), whereas no significant difference in the FRT was found (p>.05). 2) Depression level in the elderly fallers group was significantly higher than that of the elderly non-fallers group (p<.05). 3) Quality of life in the elderly fallers group was significantly lower than that of the elderly non-fallers group, excluding environment domain (p<.05). Therefore, in order for clinical evaluation of the community-dwelling elders those with reduced balancing ability, it is necessary to evaluate and understand the fall experience, depression, and quality of life.

        In this paper, the wave run-up height and depression depth around air-water interface-piercing circular cylinder have been numerically studied. The Reynolds Averaged Navier-Stokes equations (RANS) and continuity equations are solved with Reynolds Stress model (RSM) and volume of fluid (VOF) method as turbulence model and free surface modeling, respectively. A commercial Computational Fluid Dynamics (CFD) software “Star-CCM+” has been used for the current simulations. Various Froude numbers ranged from 0.2 to 1.6 are used to investigate the change of air-water interface structures around the cylinder and experimental data and theoretical values by Bernoulli are compared. The present results showed a good agreement with other studies. Kelvin waves behind the cylinder were generated and its wave lengths are longer as Froude numbers increase and they have good agreement with theoretical values. And its angles are smaller with the increase of Froude numbers.
