Besides the imposition of taxes and mandatory actions, why in a special rules needed in the contract between state and civilians. The contract between the state and civilian are unlike with civilian's contract in the comparable effect, even if the effect of the agreement and the parties bear the structural nature of the self-other agreement between private economic actors and there are a variety of different specificity. In other words, the agents of the contract with the state government for control of opportunistic behavior are very specific rules exist. Through this, even if it is the relationship between state and non-mandatory private realms of the contract, even if the area forced me to the fact that the difference can be confirmed. Representative of the government of the country to understand the delegate decisions and judgments and other opportunistic behavior always seem to exist on the possibility of such devices for the pre-control needed.

Students with learning disability have difficulty with attention and academic achievement Music can be an effective tool to enhance level of participation. The purpose of this study is to examine how much can be structured to enhance the attention span and related academic skills needed to achieve educational goals. The study has implemented structured music therapy sessions for three middle school students with learning disability. They participated in 20 sessions which were 30 minutes in length for ten weeks. The implemented music therapy sessions were designed using songs, playing, and listening to music. In order to test their level of attention, Frankfurter Aufmerksamkeits-Inventar(FAIR) Attention Test is implemented and Conners' Comprehensive Teacher's Rating Scale(CTRS-10) are used on the week before and after music activities. Also videotaping is used so as to analyze how correctly they do their task and how the correctness is changed period by period and to evaluate how often for ten minutes they make an eye contact with their teacher. The conclusions of this study are as follows: Firstly, the organized music activities have a positive affection on improving the attention of three middle school students who have learning disabilities. Fair Attention Test shows that they can do their task with more accuracy than in the previous period. Secondly, three students of this study improved their attention and made an eye contact more often than before this study, which is revealed through the analysis of the pre and post test results evaluated by CTRS-10. The results of the study indicate that structured use of music in various level of activities can help students to enhance attention span and the related academic skills.

The study is to investigate the effects of the constructivist instructional model using ARCS strategies (attention, relevance, confidence, and satisfaction) on the environmental conservation of environment textbooks of middle school. The subjects of this study were applied to 135 students sampled 2nd graders of a middle school in Busan. All students were divided three groups according to teaching strategies. The first experimental group is consisted of students who participated in the traditional teaching program, the second is students who participated in the constructivist teaching program, and the third is students who participated in the constructivist teaching program with ARCS strategies. The pre-conceptions test was administered to examine students' pre-conceptions before the instructions. After the instructions, students' acquisition of scientific conceptions, academic achievement, and learning motivation were also tested. On average, the degrees of academic achievement for the group with ARCS strategies were higher than those of other groups and shown a significant difference among three programs. Thus the constructivist teaching program with ARCS strategies was more effective programs in acquisition of environmental conservation conception and learning motivation than the two other teaching programs.

This study aims to identify and evaluate the contents of ageism and to develop instrument of ageism. Ageism instrument development remains a necessary in aging research, for the explication of actual condition of ageing. The current study describes multidimensional view of ageism toward aging and the elderly. After pre-test and review of professionals, 31 items was constructed. Data were obtained from KGSS Survey of 1535 participants. The sample was randomly divided into two group to test reliability and validity of the scale. Finally, the 23-items with seven factors were suggested, based on the internal reliability and exploratory factor analysis with the first group. Another group were conducted confirmatory factor analysis. The results showed that the final 23-item scale with seven factors had a good model fit. Development and refinement of ageism scale are necessary elements for proceeding beyond theoretical and empirical discussions in ageism. It also provides a implications for current views of ageism and strategies for reducing ageism.

This study investigates the relationship between controllability, severity, unrealistic optimism and risk perception of risk factors related to location - based SNS services for smartphone users. For this purpose, I surveyed university students who had experience using location - based SNS service. The main results are as follows. First, controllability has a statistically significant effect on unrealistic optimism. Second, Severity had a statistically significant negative impact on unrealistic optimism. Third, Controllability did not have a statistically significant effect on risk perception, Fourth, Severity did not have a statistically significant effect on perceived risk. Fifth, Unrealistic optimism had a statistically significant negative impact on perception of risk. The results of this study will contribute to the prevention of privacy incidents and the protection of smartphone users by using location - based SNS service. On the one hand, future research will need to look at the relationship between unrealistic optimism and risk prevention or coping behavior.

The purpose of this study is to identify how education and activities of urban forest healing programs affect emotional rest (healing recovery environment awareness, restoration of attention, and leisure life satisfaction). To this end, 38 people were divided into experimental groups (forest healing program education and practice), and control groups (non-program participation). As a result of the study, in the case of the experimental group, emotional rest factors such as healing recovery environment perception, attention recovery, and satisfaction with leisure activities after the program were statistically significantly improved, and in the case of the control group, there was no change in emotional rest after the program. In addition, there were differences between groups in both pre and post regarding the difference in emotional rest between the participant groups, and the difference in emotional rest afterwards was much larger than the pre-difference. In conclusion, people who receive regular education on forest healing and have done actual forest healing activities experience higher emotional rest than those who do not. This suggests that continuous motivation and regular practice can raise awareness of the healing recovery environment, promote attention recovery, and have a positive effect on leisure life through appropriate programs rather than simply taking a walk.

It has been widely accepted that the environment is an important determining factor of human health. Appreciating the relationship between the environment and human health, Korean government has begun to deal with issues of environmental health. The government proclaimed the year of 2006 to be the first year of Environmental Health and established "The Environmental Health Plan for the next 10 Year". In order to achieve the goals in the plan, there are necessary considerations such as support systems for environment health related research, investigation, law, institution, administration, and so forth. This study suggests basic principles required to establish a legal regime of environmental health which is to implement the environmental health policies in Korea. Several cases of foreign legislation and policy relevant to environmental health are reviewed. Also, existing related legal system in Korea are analysed considering legal and institutional elements for establishing an effective environmental health policy. The main purpose of amending legal system related environmental health is to protect both public health and the soundness of ecosystem. To reach the goals effectively, the concept of 'environmental health' should be clearly established and presented. In addition, an advanced prevention system, including investigation and prevention of the cause of environmental diseases and risk assessment based on the precautionary principle, are substantial in the environmental health legislation. Also the environmental health law should guarantee public participation in decision making as well as the first consideration of susceptible or vulnerable population. This study concludes that the expected legislation related to environmental health should be a nonnative instrument not only for integrating each environmental protection scheme but also for establishing and implementing the policy.

일반화 대칭 변환 (generalized symmetry transform, GST)은 주어진 영상에서 사전 분할이 없이 국부성과 반사 대칭성을 결합하여 대칭을 측정하고 관심 영역을 추출한다. GST의 거리 가중치 함수에서 국부적인 대칭성이 반영되며 이 함수의 표준 편차 u에 의해 GST의 수행 범위가 조절된다. 넓은 관심영역을 추출하기 위해 반지름 r이 큰 검색영역 내에서의 대칭성이 추출될 필요가 있다. 이에 따라서 GST의 수행시간은 r에 따라 2차적으로 증가하게 된 본 논문에서는 이를 개선하기 위해 선택적 방향 주의를 가지는 수정된 스캔라인 GST를 제안한다. 제안된 GST는 기존의 GST와 유사한 대칭 특성을 추출하지만 선택적 방향의 기울기만을 고려한 스캔라인 위의 에지 화소쌍에서 GST를 수행함으로써 r에 따라서 이의 수행시간이 선형적으로 증가된다 특히 r이 큰 경우에 선택적 방향에 대해서만 적용하면 기존의 GST의 계산량이 비대해지는 단점을 보완해 줄 수 있다. 제안된 GST가 기존의 GST보다 시간적으로 효과적이며 유용하다는 것이 여러 종류의 영상에 대한 실험으로 확인되었다.
