이 연구는 상황행위이론을 디지털 저작권침해의 다운로드와 업로드 행위에 적용함에 있어 자기통제력과 처벌억제의 통제작용을 살펴보았다. 상황행위이론에 따르면 개인의 도덕성은 높은데 도덕규칙이 약한 환경일 때는 자기통제력이, 도덕규칙 환경은 높은데 개인의 도덕성이 낮을 때는 처벌억제가 범죄에 통제요인으로 조절효과를 갖는다고 보았다. 이에 본 연구는 서울시 재학중인 317명 대학생을 대상으로 다운로드와 업로드 행위로 나누어 각각 상황행위이론의 논의를 상호작용효과 분석을 통해 검증했다. 분석결과 다운로드의 경우는 도덕성이 높지만 도덕규칙이 낮은 경우에서 자기통제력이, 그리고 도덕규칙이 높지만 도덕성이 낮을 때 처벌억제가 유의미하게 작용할 것이라는 상황행위이론을 지지하지 못했고 상호작용효과 결과가 유의미하지 않았다. 그리고 업로드의 경우는 상황행위이론과는 달리 도덕성은 높지만 도덕규칙이 낮은 경우에서 자기통제력이 업로드를 통제하기보다 오히려 유발하는 요인으로 작용하는 것을 제시했고, 또한 상황행위이론과 반대로 도덕성은 높지만 도덕규칙이 낮은 경우에서 처벌억제가 조절효과를 갖는 것을 제시했다.

이 연구는 SNS상의 범죄행위를 설명하기 위해 기존의 범죄학이론 중 사회학습이론을 중심으로 주 요인인 차별접촉, 정의, 차별강화, 그리고 모방의 영향력을 살펴보았다. 아울러 이 연구에서는 사회학습이론의 보완적 논의로 사회학습요인들이 낮은 자기통제력, 하위문화 환경, 그리고 기회요인들과 함께 작용할때더큰 영향력을 갖게 될 것이라는 점에서 그 상호작용효과를 검증하였다. 서울시 대학생 SNS이용자 486명을 조사한 본 연구에서는 사회학습요인들 중 차별접촉과 차별강화의 영향력은 대체로 유의미하지 않았던 반면 법위반에 호의적 정의와 모방의 경우는 어느 정도 SNS에서의 범죄행위에 유의미한 영향력을 갖는 것을 제시했다. 그리고 상호작용효과의 결과를 보면 어느 정도 본 연구의 가설을 지지하는 것으로 나타났다. 사회학습요인들 중에서 법위반에 대한 정의는 그것을 허용하는 하위문화 환경의 조건에서 범죄에 영향력을 갖는다는 것을 제시했고, 차별강화로서 보상은 기회요인과 함께 상호작용효과를, 그리고 모방은 자기통제력이 낮은 사람에게서 더 영향력을 갖는 것으로 나타났다.

Purpose: This study was done to examine the effects of a Program Promoting Efficacy Expectation, as to whether the program improved self-efficacy, health promotion behavior and quality of life for rural middle-aged women. The program was based on Bandura's self-efficacy theory and Pender's health promoting behavior theory. Method: The research design was a quasi experimental, nonequivalent control group pretest-posttest design. Data were collected from August 25 to December 7, 2000. The participants were 40 to 59 year old women who resided on Je-ju island. Among the 83 participants, 43 were assigned to experimental group and the rest to the control group. Results: The level of self efficacy and the degree of health promoting behavior of participants in the experimental group was higher than those in the control group (t=12.82, p=0.0001; t=14.13, p=0.0001). Also, the level of quality of life in the experimental group was higher than that of the control group (t=12.02, p=0.0001). Conclusion: The Efficacy Expectation Promotion Program was an effective nursing intervention for improving self-efficacy, health promotion behavior and quality of life. Therefore, when nurses are planning programs directed at improving health promotion behavior in rural middle aged women, they should consider the concept of self-efficacy.

The self-tuning control theory which has so far been studied has the type of a moving average noise mode. In this paper we propose a self-tuning munimum varinace control of the plant with an autoregressive noise model. New identities are introduced to find a munimum variance control input, and the stability and convergence properties in a closed loop system are studied using the BIBO concepts and ODE method. Also the proposed algorithm is compared withe that of the original self-tuning control by computer simulation.

In this paper, the hybrid state space self-tuning control technique Is studied within the framework of fuzzy systems and dual-rate sampling control theory. We show that fuzzy modeling techniques can be used to formulate chaotic dynamical systems. Then, we develop the hybrid state space self-tuning fuzzy control techniques with dual-rate sampling for digital control of chaotic systems. An equivalent fast-rate discrete-time state-space model of the continuous-time system is constructed by using fuzzy inference systems. To obtain the continuous-time optimal state feedback gains, the constructed discrete-time fuzzy system is converted into a continuous-time system. The developed optimal continuous-time control law is then convened into an equivalent slow-rate digital control law using the proposed digital redesign method. The proposed technique enables us to systematically and effective]y carry out framework for modeling and control of chaotic systems. The proposed method has been successfully applied for controlling the chaotic trajectories of Chua's circuit.

Purpose: This study aimed to develop a motivational interviewing pulmonary rehabilitation program based on self-determination theory to maintain pulmonary rehabilitation-related health behaviors in patients with chronic obstructive pulmonary disease. The program was developed by reviewing the literature on pulmonary rehabilitation guidelines, drawing on the self-determinism theory to establish its contents, recruiting experts to test its validity, and conducting a preliminary survey. Methods: A quasi-experimental design was used to confirm the effect of the program. The participants were outpatients diagnosed with chronic obstructive pulmonary disease at three general hospitals in Busan. There were 33 subjects: 15 in the experimental group and 18 in the control group. The experimental group performed a motivational interviewing pulmonary rehabilitation program which comprised 11 sessions delivered over 10 weeks. The outcomes were measured using basic psychological needs, dyspnea, 6-minute walking distance, and functional status. Intervention effects were analyzed using repeated-measures ANOVA. Results: The analysis revealed significant differences between the experimental and control groups in competence among the subdomains of basic psychological needs, dyspnea during exercise, and functional status. Conclusion: The developed program affects physical conditions and can be applied as an effective clinical nursing intervention to continuously improve the pulmonary rehabilitation behavior of patients with chronic obstructive pulmonary disease.

Purpose: The study aimed to design and develop an automated personalized self-care (APSC) program for patients with type 2 diabetes mellitus. The secondary aim was to present a clinical protocol as a mixed-method research to test the program effects. Methods: The APSC program was developed in the order of analysis, design, implementation, and evaluation according to the software development life cycle, and was guided by the self-regulatory theory. The content validity, heuristics, and usability of the program were verified by experts and patients with type 2 diabetes mellitus. Results: The APSC program was developed based on goal setting, education, monitoring, and feedback components corresponding to the phases of forethought, performance/volitional control, and self-reflection of self-regulatory theory. Using the mobile application, the participants are able to learn from educational materials, monitor their health behaviors, receive weekly-automated personalized goals and feedback messages, and use an automated conversation system to solve the problems related to self-care. The ongoing two-year study utilizes a mixed method design, with 180 patients having type 2 diabetes mellitus randomized to receive either the intervention or usual care. The participants will be reviewed for self-care self-efficacy, health behaviors, and health outcomes at 6, 12, 18, and 24 months. Participants in the intervention group will be interviewed about their experiences. Conclusion: The APSC program can serve as an effective tool for facilitating diabetes health behaviors by improving patients' self-care self-efficacy and self-regulation for self-care. However, the clinical effectiveness of this program requires further investigation.

Purpose Despite the continued rise in the popularity of mobile MMORPGs, the previous studies mainly focused on negative results of playing MMORPG such as violence and game addiction. In addition, previous studies that verified game play motives were not enough to explain user's fundamental motives for MMORPG play. To verify the positive role of playing MMORPG, this study focused on stress coping strategies on continued play MMORPG, and divided factors into two dimensions: escapism and coping with system. The purpose of this study is to comprehensively identify the discriminatory effects of each factor on users' self-control, and the effect of self-constrol and behavioral adapatation on continued use intention for MMORPG. Design/methodology/approach This study was designed to examine the structural relationships among MMORPG users' escapism, system coping, self-control, behavioral adaptation and continued use intention for MMORPG. Findings The results from this study are as follow. First, the participants' effect-based escapism had a positive impact on self-control, whereas cause-based escapism had a negative impact on self-control. Next, proactive coping and reactive coping for system problem had a positive impact on self-control. In addition, Self-control had a positive impact on behavioral adaptation and continued use intention for MMORPG. Lastly, the behavioral adaptation to MMORPG had a positive impact continued use intention. The results of our study can suggest the positive effects of coping strategy on users' self-control and behavioral adaptation by applying the theory of both escapism and coping with system. Based on our results, game companies should develop contents that can gratify users' coping motives and enhance self-control and behavioral adaptation.
