  • Purpose: The purpose of this study was to identify predictors on drinking problems of university students. Methods: The participants were 359 students by convenience sampling in P city. Data were collected from October 15 to December 20, 2007 using drinking problems questionnaire, Global assessment of recent stress scale, CES-D and self-esteem scale. The collected data were analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression. Results: There were positive correlations between stress and drinking problems, between depression and drinking problems. Also, there were negative correlations between stress and self-esteem, between depression and self-esteem. In stepwise multiple regression analysis, the most powerful predictor of drinking problems was depression. Conclusion: The results suggest that effective management of depression and stress can be considered when developing a prevention program of drinking problems for university students.

  • Purpose: The purpose of this study was to examine the level of occupational stress and depression in clinical nurses and to investigate the effects of subscales of occupational stress on depression. Method: A sample consisted of 202 nurses from 6 hospitals located in Busan and GyeongNam province. The data were collected from November 2008 to march 2009. A self-administered questionnaire was used to assess socio-demographics, job characteristics, depression measured by Korean CES-D, and occupational stress assessed by KOSS. Result: The total score of occupational stress in clinical nurses was within bottom 25%, but the scores of 'Difficult physical environment', 'High job demand', 'Inadequate social support', 'Organizational injustice' were within top 50%. The 8 subscales of occupational stress had significantly effects on clinical nurses' depression after controlling for age, marital status, type of hospital, current position. Conclusion: The administration of employee assistance program for management occupational stress is important for decreasing depression in clinical nurses.

  • 안경제품의 경우 디자인이 제품의 판매력 향상에 미치는 영향이 크며, 디자인에 따라 2~4배까지 가격차가 발생하는 등 다른 어떤 상품보다도 디자인의 부가가치 창출효과가 매우 크다고 할 수 있다. 특히, 지금의 안경산업은 기술과 품질력은 '생존경쟁'의 기본이고, 디자인과 브랜드는 '고속성장'의 기본이다. 중국을 비롯한 홍콩, 동남아시아의 후발 경쟁국들이 모든 분야에서 추격해 오고 있는 현실에서 디자인과 브랜드육성에 관심과 문제 해결방안을 위한 다각적인 노력과 방안이 지속적으로 추진된다면 우리나라 안경산업의 경쟁력 확보와 이를 통한 수출 증대의 가능성은 획기적으로 높아질 것이다.

  • MW-class gas turbines are suitable for distributed generation systems such as community energy systems(CES). Recently, biogas is acknowledged as an alternative energy source, and its use in gas turbines is expected to increase. Steam injection is an effective way to improve performance of gas turbines. This study intended to examine the influence of injecting steam and using biogas as the fuel on the operation and performance a gas turbine combined heat and power (CHP) system. A commercial gas turbine of 6 MW class was used for this study. The primary concern of this study is a comparative analysis of system performance in a wide biogas composition range. In addition, the effect of steam temperature and injected steam rate on gas turbine and CHP performance was investigated.

  • Cauda equina syndrome(CES) and disc hemiation have been implicated as a potential complication of Chuna Manipulation Treatment. We reported a man who developed sudden complication alter lumbar Chuna Manipulation Treatment. It is supposed that this patient suffered a disc herniation secondarily due to a lumbar Chuna Manipulation Treatment. Therefore, doctors should be aware that neurological complication may occur as a result of lumbar Chuna Manipulation Treatment.

  • Virginiae butanolide C(VB-C) is one of the butyrolactone autoregulators, which triggers the production of virginiamycin in Streptomyces virginiae. Streptomyces longwoodensis was selected as a test strain to investigate new VB-C functions. When 100 ng/ml of the synthetic VB-C was added into the culture at 5 hour and 0 hour, the initial production time of antibiotics and a dark blue pigment were shortened by 4~6 hours and 2~4 hours, respectively. HPLC analysis revealed the production of several new antibiotics by VB-C addition. In the SDS-PAGE analysis of the total protein from mycelium several new protein bands showed up and the amounts of certain protein bands increased in the presense of VB-C. The existence of specific VB-C binding protein was confirmed from S. longwoodensis in relation to VB-C signal transduction. These results suggest that the VB-C might have an ability to induce the production of secondary metabolites in Streptomy- ces longwoodensis.

  • The purpose of this paper is to investigatethe relationship between Korean elementary teachers' teaching practice and students' perceptions of classroom learning environment. It is important to examine whether teachers conceive of mathematics and their teaching practice are consistent with their actual teaching mathematics in classroom. To do so, two reform-oriented and two traditionally-oriented elementary teachers in Seoul and a total of 130 students from these four selected teachers' classes participated in the present study Using classroom environment survey scale [CES] the differences in students' perceptions on classroom learning environment were examined. The results show that students taught by reform-oriented teachers have significantly higher score in the area of participation, relevance, and commitment to learning than traditionally-oriented group of students. Thus, we may conclude that the reform-oriented group of students have more benefits in learning mathematics than do the traditionally-oriented group of students.

  • The main purpose of this study was to examine the impact of religious participation on the depression of elder adults in USA. Specifically, this study examined how the influence of religious participation varied according to continuity or discontinuity of participation. Data from N=1,658 adults aged 65-90 who were respondents to two waves of the U.S. National survey of Families and Households 1987-1993 were used for these analyses. Depression was measured with a 12-item (of the original 20) modified version of the CES-D (Center for Epidemiological Studies-Depression). Multivariate regression models controlling for several demographic variables were estimated. Some clear evidence was found supporting activity theory and continuity theory That is, participating in a religious organization role at Time 2 but not Time 1 (T1 No - T2 Yes) and being continuously involved in religious organizations both at Time 1 and Time 2 (T1 Yes -T2 Yes) were associated with reduced depression, compared to continuous nonparticipation in religious organizations (71 No -72 No).

  • The field-surveyed and measured energy consumption data is processed to develop building energy demand models for heating, hot water, cooling, and electricity. The load models are systematically organized as a database and hourly loads for a span of year (8760 hours) are generated by the program. Rased on those models a Microsoft Access application program is developed to calculate energy demands for a Community Energy System (CES) composed of 17 types of buildings. User-friendly interfaces are provided to assist non-expert end users and necessary tools to link the calculation results to subsequent coagulations such as operation simulation or economic assessment.
