Objectives: This study was done to find out fatigue and self-reported physical symptoms of Vinylhouse farmers. The results of this study could be used as a basic data to develop health promotion program for Vinylhouse farmers who are suffering from fatigue and physical symptoms. Methods: The 166 respondents, who were working in Vinylhouse and were living in a remoted area where the primary health post located, were participated in this study. Thirty: 30 items of self-reported fatigue scale was used to evaluate the farmers fatigue level which made by Japanese industrial and hygenic association(1988). Twenty four: 24 items of index used by researcher for self-reported physical symptoms was from Lee In Bae's(1999) modified Index which was originated from Cornell Medical Index(1949). Another questionnaires used in this study were developed by researcher through related documents. Results: The results of this study were as follows; Fatigue scores were high in accordance with women(t=-2.212, p<0.05), worse recognized health state(F=20.610, p<.001), lack of sleeping hours(F=3.937, p<0.05), eat irregularly(t=-3.883, p<0.001), don't take a bath after application of chemical(t=-2.950, p<0.01), working time per a day(F=5.633, p<0.01) & working time per a day in Vinylhouse(F=5.247, p<0.01) were long. Subjective physical symptoms were high in accordance with women(t=-3.176, p<0.01), worse recognized health state(F=35.335, p<0.001), and low education(F=3.467, p<0.05). eat irregularly(t=-3.384, p<0.01), alcohol drinking(t=-2.389, p<0.05). When farmers don't take a bath after application of chemical show high(t=-3.188, p<0.01). As a result, the factors affecting to Vinylhouse worker's health were irregular diet habit, scarce exercise, lack of proper rest, symptoms oriented from Vinylhouse work in contaminated environment with high temperature and humidity. Conclusions: Based on this study, health promotion program is necessary for Vinylhouse workers. Also, the development of continuously practical strategy of healthy life style including exercise and comprehensive health promotion program considered the country's social and cultural background are needed.

Economic sanctions and inducements are types of 'policy instruments' based on 'economic tools' to influence other international actors. Ongoing debates on sanctions and inducements have exposed drawbacks for relying on individual case studies. There are some studies in the literature that attempt theoretical analysis of sanctions and inducements, but they are mostly based on rational choice theory. In reality, however, there exist so many cases that cannot be explained by rational choice theory. These are called anomalies or exceptions. The literature introduces specific variables to interpret these anomalies and thus sacrifice the universality of the theory. From this point of view, prospect theory would present an effective tool to analyze economic sanctions and inducements. It is a behavioral economic theory that tries to model a decisions making process in reality. The theory says that people make decisions based on subjective value of losses and gains from an individual reference point, and that people evaluate these losses and gains using heuristics. Thus prospect theory could offer a different frame which has greater explanatory range without adding new variables. As a result of this study, target's losses of 'back down' towards economic sanctions loom larger when the reference point level increases, therefore, the effectiveness of sanctions decreases. However, target's losses of 'stand firm' towards economic inducements loom larger under the same condition of reference point, therefore, the effectiveness of inducements increases. The findings of the paper suggest meaningful implications to the economic policy towards North Korea.

Ecotourism is an alternative tourism which can be defined as responsible tourism in natural areas. This study deals with changing the tourists' environmental attitudes of ecotourism activities based on the elaboration likelihood model(ELM). The surveys were conducted based on the same participants to clearly measure the differences of environmental attitudes between pre and post-participation ecotourism activities. A total of 183 samples were collected in Upo Wetlands. The results showed that there were significant differences in the tourists' environmental attitudes between pre and post-participation ecotourism activities. This indicates that ecotourism participants delicately reinforce their eco-friendly attitudes through various ecotourism experiences and educational programs. The most significant finding is that anti-environmental behavior can be relieved with eco-friendliness through participation in ecotourism.

The purpose of this descriptive research study was to investigate health beliefs and self-efficacy in respiratory infection management as factors that affect the respiratory infection prevention behavior of college students. The subjects were 178 students attending a university in K city of Gyeongsangbuk-do. Data were collected with a structured questionnaire from September 1st to October 16th of 2020. The results of this study are as follows; Health belief was significantly different from participant's gender (t=-2.86, p=.005), major classification (F=2.95, p=.034), and taking any medications (t=2.18, p=.030). Self-efficacy in respiratory infection management was significantly different from university students' gender (t=-3.56, p=<.001) and major classification (F=4.59, p=.004). Health belief (r=.276, p<.001) and self-efficacy in respiratory infection management (r=.660, p<.001) had a positive correlation with respiratory infection preventive behavior. Multiple regression analysis results show that self-efficacy in respiratory infection management (β=.66, p<.001) significantly affected respiratory infection preventive behavior. The model had an explanatory power of 43%. The findings demonstrate that the major factor influencing the respiratory infection preventive behavior of university students is self-efficacy in respiratory infection management. Therefore, in order to promote behavior to prevent respiratory infection in college students, a program that can strengthen self-efficacy in respiratory infection management should be developed.

Security has been a major concern in software development. Security tactics are reusable building blocks providing a general solution for recurring security concerns at the architectural level. They are often used together with architectural patterns which provide a general solution for architecting software systems. However, use of security tactics in architectural patterns has been understood only conceptually without concrete understanding of how their involved elements should be structurally and behaviorally co-designed. In this paper, we present model-driven analyses of security tactics in the context of Broker architectural patterns and provide evidences of the analyses in real world case studies.

Purpose: This study aimed to comprehend the real context of metabolic syndrome-related factors of Korean male blue-collar workers from small-sized companies based on the health belief model. Methods: A total of 37 workers from three companies were interviewed, and three series of focus group interviews were conducted. Data were analyzed using deductive content analysis. Results: Data were classified into four categories: knowledge, perceived susceptibility and severity, perceived barriers, and beliefs. Knowledge referred to low knowledge level; perceived susceptibility and severity referred to unawareness of susceptibility and severity; perceived barriers referred to shift work, overtime work, and a social context including having no choice but to drink; and beliefs referred to believing that health promotion behaviors do not relate to preventing metabolic syndrome, believing that one cannot prevent metabolic syndrome oneself, and believing that professional help is required. Conclusion: To prevent and reduce the risk of metabolic syndrome among Korean male blue-collar workers, interventions should focus on strategies to increase metabolic syndrome-related knowledge and perceptions, social support, and self-efficacy for practicing health behaviors. In addition, it is necessary to develop policies for establishing a healthy drinking culture in companies.

미국 911 테러 발생 이후로, 국가 기반시설(예: 송/배전 전력망, 석유/가스 파이프라인, 원자력 발전소, 정보통신 시설, 교통 시설, 금융 시설, 매스미디어 시설 등)에 대한 테러리스트의 사보타지 리스크를 관리하는 도전문제에 정부 차원이나, 기업 차원에서 국내외적으로 뜨거운 이목이 집중되고 있다. 그 가운데 에너지 시스템, 특히 원자력 발전소의 물리적 보안은 국가 안보 차원에서 매우 중대한 이슈가 되고 있다. 이는 사보타지로 인한 이러한 시스템의 파손이 국민, 작업자, 또는 외부 환경에 방사성물질 누출과 같은 중대한 결말을 초래할 수 있기 때문이다. 원전과 같은 복잡 시스템에서 설계 기준 위협이 초래할 수 있는 이러한 결말은 그 시스템의 특정 핵심 표적(예: 부품, 구역, 자산, 행위, 인원)의 방호를 통해 효과적으로 방어될 수 있다. 다시 말하면, 표적 인식에서는 어떻게 방어할 것인가에 앞서서 무엇을 방어할 것인가를 다루려는 것이다. 이 연구의 주요 목적은 여태까지 개발된 다양한 표적 인식 기법의 개발 추세를 소개하고 향후 전망을 제시하는 데에 있다. 이를 통해 표적 인식 기법의 수월성, 신뢰성, 및 경제성을 제고할 수 있으리라 본다. 표적 인식 기술의 활용성 측면에서 볼 때, 표적 인식은 하드웨어 적이거나 소프트웨어적인 방호 시스템의 설계에 필수적이므로, 신뢰성 높은 표적 인식은 다음과 같은 긍정적인 파급 효과를 줄일 수 있다: 1) 사보타지 리스크 감소에 직간접적으로 기여할 수 있다; 2) 제한적인 보안 재원을 효율적으로 할당할 수 있다; 3) 보안 대응군대의 훈련 시나리오를 개발할 수 있다; 4) 발전소 규제요건인 안전조치 계획을 비용이나 보안 측면에서 향상시켜 국민 안심(public easiness)을 도모할 수 있다. 향후에는 보다 더 광의적인 복잡 시스템 사이에서 상호 연계적인 사보타지에 대한 표적 인식의 기법들이 점검될 필요성이 있다고 본다.

Software requirement analysis is necessary for successful software development project. Specially, incomplete requirement is the most influential causes of software project failure. Incomplete requirement can bring late delay and over budget because of the misunderstanding and ambiguous criteria for project validation. Software requirement patterns can help writing more complete requirement. These can be a reference model and standards when author writing or validating software requirement. Furthermore, when a novice writes the software scenario, the requirement patterns can be one of the guideline. In this paper proposes an automatic approach to identifying software scenario patterns from various software scenarios. In this paper, we gathered 83 scenarios from eight industrial systems, and show how to extract 54 scenario patterns and how to find omitted action of the scenario using extracted patterns for the feasibility of the approach.
