Purpose: The purpose of this study was to propose and to test a predictive model that could explain the workers' quality of life. Methods: Data were collected using self-report questionnaires from 901 workers in Daejeon, Korea. The questionnaires included nine measured variables (safety culture, self-efficacy, activity of occupational health provider, knowledge in occupational health, age, health promotion behavior, workplace environment, health level, and quality of life), as revised PRECEDE model has suggested. The collected data were analyzed using SPSS/WIN 15 and AMOS 6.01 version. Results: Based on the constructed model, behavior, environment, and health were found to have significant direct effect on quality of life. Indirect factors were perceived biological, predisposing, reinforcing, and enabling. The proposed model was concise and extensive in predicting quality of life of the participants. The final modified model yielded GFI=.85, AGFI=.89, NFI=.79, and RMSEA=.11 and exhibited good fit indices. Conclusion: Findings of this study may contribute to development of effective nursing interventions for promoting quality of life in workers.

Purpose: This study was to develop and test a theoretical model based on the revised health belief model explaining osteoporosis prevention behaviors among postmenopausal women under 65. Methods: This secondary data analysis included 342 postmenopausal women under 65 from original data sources of a total of 734 women. The measured instruments were scales for osteoporosis awareness, osteoporosis health belief scale (benefit, barrier, susceptibility, severity, and health motivation), self-efficacy, and osteoporosis prevention behaviors. Data were analyzed using SPSS/WIN 20.0 and AMOS 20.0. Results: The mean age of the subjects was 55.2 years and the mean age of menopause was 51.10. The hypothetical model of osteoporosis prevention behaviors was relatively fit. Osteoporosis prevention behaviors were significantly explained up to 62% by expectation factors (relative benefit, self-efficacy, health motivation) and modifying factors(knowledge only). Expectation factors of health belief had a mediation effect between modifying factors and prevention behaviors. Conclusion: This study partially supported the revised health belief model for explaining osteoporosis prevention behaviors. It provides a basis for developing an educational program focusing on expectation factors and knowledge with the aim of behavioral changes for osteoporosis prevention.

Purpose: The aim of this study was to develop and test an explanatory model for sleep disorders in people with cancer. A hypothetical model was constructed on the basis of a review of previous studies, literature, and sleep models, and 10 latent variables were used to construct a hypothetical model. Methods: Data were collected from April 19 to June 25, 2010, using self-report questionnaires. The sample was 291 outpatients with cancer who visited the oncology cancer center at a university hospital. Collected data were analyzed using SPSS Win 15.0 program for descriptive statistics and correlation analysis and AMOS 7.0 program for covariance structural analysis. Results: It appeared that overall fit index was good as ${\chi}^2/df=1.162$, GFI=.969, AGFI=.944, SRMR=.052, NFI=.881, NNFI=.969, CFI=.980, RMSEA=.024, CN=337 in the modified model. The explanatory power of this model for sleep disorders in people with cancer was 62%. Further, sleep disorders were influenced directly by cancer symptom experience, dysfunctional beliefs and attitudes about sleep, and past sleep pattern. Conclusion: Findings suggest that nurses should assess past sleep pattern and consider the development of a comprehensive nursing intervention program to minimize the cancer symptom experience, dysfunctional beliefs and attitudes about sleep, and thus, reduce sleep disorders in people with cancer.

컴퓨터 자원의 대용량화 및 네트워크 속도의 증가로 인하여 사용자가 네트워크를 통해 원격지의 서버에 접속하여 컴퓨터론 사용하는 요구가 증가되었다. 이에 따라 중앙집중형 컴퓨팅을 통한 응용프로그램 제공 서비스도 활성화되었다. 중앙집중형 컴퓨팅 시스템은 중앙의 대용량컴퓨터 시스템에 설치된 응용프로그램을 공유 프로토콜을 통하여 원격 사용자에게 제공하는 응용프로그램 공유 서비스(ASP： Application Service Provision) 시스템 모델이다. 중앙집중형 컴퓨팅 시스템을 통한 응용프로그램 공유 서비스는 기밀성, 가용성 무결성 등의 보안 사항이 반드시 유지되어야 한다. 기존 원격 컴퓨팅인 Telnet, FTP 접속은 단순히 파일 및 데이터의 접근 권한을 제어함으로 보안이 유지된다. 그러나 윈도우 기반 시스템의 경우 다수의 사용자가 통일한 권한을 통해 통일한 응용프로그램을 제공받기 때문에 사용자들 사이에 기밀성 및 무결성을 저해 할 수 있다. 또한 다수의 사용자가 하나의 응용프로그램에 파일열기, 복사, 서식 수정 등의 여러 기능 명령어를 전송하기 때문에 파일 및 데이터 접근 제어만을 통해서는 시스템의 기밀성 유지한 수 없다. 또한 기밀성의 문제는 곧 가용성 및 무결성의 문제로 이어질 수 있다. 본 논문에서는 윈도우 기반 중앙집중형 컴퓨팅 시스템의 응용프로그램 공유 서비스를 지원함에 있어 사용자가 실행하는 Win32 API 메시지 명령어 접근제어 시스템을 제안한다. 제안하는 시스템은 GUI(Graphical User Interface) 기반의 서버에서 사용자가 서버에 접속하여 발생하는 모든 메시지(마우스, 키보드, I/O, etc....)들을 감시한다. 감시된 메시지 기반의 명령어는 미리 설정된 사용자별 보안 정책에 기반 하여 해당 응용프로그램에게 전달 여부가 결정된다. 이러한 메시지 기반 상세 보안을 통해 기밀성 침해의 우려가 있는 메시지 명령어를 차단하고, 기능 명령어 차단에 의한 자원의 기밀성을 해결하였다.

Purpose: This study was done to develop a prediction model for postpartum depression by verifying the mediation effect of antepartum depression. A hypothesized model was developed based on literature reviews and predictors of postpartum depression by Beck. Methods: Data were collected from 186 pregnant women who had a gestation period of more than 32 weeks and were patients at a maternity hospital, two obstetrics and gynecology specialized hospitals, or the outpatient clinic of K medical center. Data were analysed with descriptive statistics, correlation and exploratory factor analysis using the SPSS/WIN 18.0 and AMOS 18.0 programs. Results: The final modified model had good fit indices. Parenting stress, antepartum depression and postpartum family support had statistically significant effects on postpartum depression, and defined 74.7% of total explained variance of postpartum depression. Antepartum depression had significant mediation effects on postpartum depression from stress in pregnancy and self-esteem. Conclusion: The results of this study suggest that it is important to develop nursing interventions including strategies to reduce parenting stress and improve postpartum family support in order to prevent postpartum depression. Especially, it is necessary to detect and treat antepartum depression early to prevent postpartum depression as antepartum depression can affect postpartum depression by mediating antepartum factors.

Recently, AI pilots using reinforcement learning are developing to a level that is more flexible than rule-based methods and can replace human pilots. In this paper, a curriculum was used to help head-on combat with reinforcement learning. It is not easy to learn head-on with a reinforcement learning method without a curriculum, but in this paper, through the two circle-based head-on air combat learning technique, ownship gradually increase the difficulty and become good at head-on combat. On the two-circle, the ATA angle between the ownship and target gradually increased and the AA angle gradually decreased while learning was conducted. By performing reinforcement learning with and w/o curriculum, it was engaged with the rule-based model. And as the win ratio of the curriculum based model increased to close to 100 %, it was confirmed that the performance was superior.
