우울은 군대 내 발생되는 극단적인 사고 중 하나인 자살의 주요 원인으로 제시되어 왔다. 본 연구는 군인들의 우울, 불안 및 자아존중감의 수준을 파악하고, 우울의 영향요인을 탐색하고 이들을 예측하는데 주로 사용해 왔던 다중회귀분석 방법과 효과적인 의사결정방법으로 알려진 회귀나무모형의 효과성을 비교해보고자 하였다. 방법: 횡단적 조사연구이며, 우울측정에는 CES-D, 불안측정은 SAI, 자아존중감은 Rosenberg(1965)의 도구를 사용하였다. 연구대상자는 강원도 전방 부대 근무 중인 군인이며, 534부가 회수되었다. SPSS/WIN 18.0을 이용하여 위계적 다중회귀분석과 회귀나무모형을 실시하였다. 결과: 대상자들의 우울, 불안 및 자아존중감의 정도는 각각 $10.7({\pm}9.8)$, $38.5({\pm}10.2)$과 $31.7({\pm}5.2)$이었다. 대상자의 23.6%(126명)가 경한 우울을 나타내었다. 다중회귀분석에 의한 우울 영향요인은 불안, 자아존중감과 복무기간이었으며, 우울에 대하여 62.0%의 설명력을 가지고 있었다. 또한 회귀나무모형에서는 높은 불안과 불안이 다소 낮더라도 전역 후 진로가 불확실한 집단이 우울 위험군일 것으로 예측되었다. 결론: 본 연구 대상자들의 우울의 주요 영향요인은 불안으로 나타났다. 군대 내에서 적용할 수 있는 불안 조절 방법 개발이 필요할 것으로 보인다. 또한 일부 요인에서 차이가 있어, 반복 연구가 필요하지만, 주요 변인인 불안을 예측했다는 점에서 보면 다중회귀분석과 회귀나무모형은 군인들의 우울을 예측에 유용한 방법으로 보인다.

Kinesin은 Saccharomyces cerevisiae, Aspergillus nidulans, Drosophila melanogaster 등에서 발견 되었으며 dynein 과 더불어 세포분열 과정중 chromosome 의 이동과 spindle pole 의 분리에 관련된 것으로 알려져 있다. 본 연구에서는 기존에 발견된 kinesin 유사 유전자의 homology 가 많은 motor domain을 이용하여 primer를 합성한 후 이를 이용하여 Schizosaccharomyces pombe 로부터 kinesin heavy chain 의 유전자를 클론하였다. 염기서열을 결정한 결과 2496 bp의 해독틀을 가지고 있으며 832개의 아미노산으로 이루어진 분자량이 96 kd의 kinesin heavy chain을 암호화하는 것이 밝혀졌다. 기존에 밝혀진 다른 organism 의 kinesin 과 서열을 비교한 결과 새로이 클론된 S.pombe 의 kinesin 은 C-terminal motor subfamily 에 속함이 밝혀졌다.

A simulation program is developed for analysing thermal networking process between the District heating and the CES(Community Energy Supply) systems. The effects of thermal networking on the District heating facilities previously being operated are implemented using mathematical correlations in terms of the fuel consumption and energy load such as heating and electricity. The operational characteristics according to the prime movers is modeled based on the materials of efficiency as a function of operational load. The unit energy load model is also developed extensively for several building types such as apartment complex, hotel, hospital, buildings for business and commercial use respectively. The specific features of the newly developed program in simulation of thermal networking process in district heating is described in terms of the reliability and the easiness for operating it etc.

Enhanced ICRF (Ion Cyclotron Range of Frequency) ion heating of H-mode D(H) plasma will be tried in 2011 KSTAR experimental campaign. Minority heating is a main ion heating scheme in the ICRF. Its efficiency increases as the hydrogen minority ratio increases in deuterium plasmas. And it should be sustained at a lower level than the critical minority ratio. Consequently, it is important to elevate the critical ratio to maximize ion heating and it is possible by increasing the ion temperature or parallel wave number (k${\parallel}$) of the antenna. Increasing the k${\parallel}$ is not a good approach since the coupling efficiency decreases exponentially with regard to k${\parallel}$ as well. So the remaining method is to increase ion temperature by using NB (Neutral Beam). Ion heating fraction of NB increases as the electron temperature increases. Therefore, we will try to heat electron by using ECH together with NB ion heating before ICRF power injection. The ICRF heating efficiency will be compared with respect to several NB+ECH+ICRF heating combinations through several diagnostics such as XICS (Xray Imaging Crystal Spectroscopy), CES (Charge Exchange Spectroscopy) and neutron measurement. The theoretical background and the experimental results will be presented in more detail in the conference.

The purpose of this study was to explain the influence of depression on the life satisfaction of the elderly with hypertension. Also, we were focusing whether there is a mediating effect of subjective health status between depression and life satisfaction of the elderly with hypertension. 2,198 persons with hypertension over 65 years of age were selected from the data of KLoSA(Korean Longitudinal Study of Ageing), administered by The Korea Employment Information Service in 2014. Life satisfaction was measured by 10-Likert. The depression measured by CES-D10. The mediating variable is subjective health status measured by 5-Likert. As the method of analysis, the multiple regressions were used with SPSS 19.0. The result of the study shows that depression has a negative influence on life satisfaction and a negative influence on subjective health status. It was also verified that the subjective health status variable has a mediating effect between depression and life satisfaction. These results present the importance of psychological approach for the health promotion experts intervening with the elderly with hypertension.

The purpose of this study was to identify the long-term effects of the self-help program for arthritis patients. The subjects were 126 patients who have participated in the 6-week self-help program from 1997 to 2000, agreed to participate in this study by telephone interview and responded the mailed questionnaires. The measurement tools of this study were all self-reported questionnaires such as Numerical Pain Rating Scale, the number of pain sites, Korean Health Assessment Questionnaire, Numerical Fatigue Rating Scale, CES-D depression scale, Self-efficacy scale, Social support scale. The repeated measure ANOVA revealed the significant differences among the pre post follow-up pain and fatigue. Whileas there were no significant differences the pre post follow-up pain site and physical functioning. And there were also no significant differences the pain, pain site, fatigue and physical functioning among three groups according to the duration of follow-up. These results suggested that the follow-up program after the self-help program was completed would be helpful for the physical wellbeing of arthritis patients.

Work related musculoskeletal disorders (WMSDs) have become a hot issue within the Korean workplace for the past several years. Recently, the effect of job related stress on WMSDs, cerebro-cardiovascular diseases, and psychiatric disorders has been steadily increasing. The study conducted questionnaire of Korea version job stress model, WMSDs from NIOSH, CES-D (Center for Epidemiologic Studies Depression Scale), and STAI (State-Trait Anxiety Inventory) against train drivers. The results of this study show that the job stress score of the train drivers is high in the areas of physical environment, job latitude, interpersonal conflict, job insecurity, and organization system. The relation between job stress and WMSDs nd, interpersonal conflict, job insecurity and organizational system. The relation between job stress and depressive disorders showed statistical significance in the areas of job demand, job insecurity and low reward. Finally, the relation between job stress and anxiety disorders showed statistical significance in areas of job demand, interpersonal conflict, job insecurity, organizational system and low reward.

본 논문은 셀 사이트에서 다양한 트래픽을 수용하기 위한 이동 백홀 네트워크에서 QoS 기능에 관한 것이다. RAN 시스템의 스위칭 기능에 할당된, 이더넷 프레임, IP 패킷, 그리고 ATM 셀과 같은 트래픽은 세그먼트된 후 이동백홀 네트워크로 전달되기 전에 캡슐화 된다. ISP는 표준의 pseudowire 캡슐화를 통하여 all IP RAN 상에 음성 및 HSPA와 같은 모든 세대의 트래픽을 통합할 수 있다. 이것들은 다양한 QoS 방법뿐만 아니라 포괄적인 모니터링 및 진단 능력을 통하여 강화될 수 있다. 따라서 본 논문에서는 이와 같은 동작상에서 QoS 기능들이 서로 다른 갭슐 방법에 따라 시뮬레이션 되었다.

Purpose: The objective of this study was to examine the correlation between HbA1C, self-care behavior, and quality of life among depressed and non-depressed patients with type II diabetes Methods: Data were collected between May 26 and July 5, 2011 using a questionnaire. The questionnaire included depression (CES-D), self-care behavior and quality of life. Hemoglobin A1C was ed from medical records. Data were analyzed by descriptive statistics, t-test, $x^2$-test, ANCOVA and Pearson's correlation coefficient. Results: In this study sample (n=301), 20.9% of diabetic patients (n=69) were depressed. After adjustment for relevant covariates, depressed patients showed to have lower self-care behavior (2.8 vs 3.4, p<.001) and quality of life (2.8 vs 3.5, p<.001) scores, but the difference in HbA1C was no longer significant. Conclusion: This study suggests that the assessment and intervention for depressed diabetic patients can result in effective self-care behavior, which accordingly leads to improvement of the quality of life.
