Sports activities conducted by multiple people are difficult to proceed in a situation where a widespread epidemic such as COVID-19 is spreading, and this causes a lack of physical activity in modern people. This problem can be overcome by using online exercise contents, but it is difficult to check detailed postures such as during face-to-face exercise. In this study, we present a model that detects posture and tracks movement using IT system for better non-face-to-face exercise content management. The proposed motion tracking model defines a body model with reference to motion analysis methods widely used in physical education and defines posture and movement accordingly. Using the proposed model, it is possible to recognize and analyze movements used in exercise, know the number of specific movements in the exercise program, and detect whether or not the exercise program is performed. In order to verify the validity of the proposed model, we implemented motion tracking and exercise program tracking programs using Azure Kinect DK, a markerless motion capture device. If the proposed motion tracking model is improved and the performance of the motion capture system is improved, more detailed motion analysis is possible and the number of types of motions can be increased.

School forests, an important part of the urban forest, has diverse functions and plays an important role in artificial environment. It has three main functions: educational for children, ecological for nature, and cultural for residents. In spite of its diverse functions and roles, the actual conditions and achievements of school forests have not been correctly evaluated, resulting in institutional inertia. To improve these problems, this study was synthetically conducted by the post occupancy evaluation of users(residents, teachers and students) at school forests. This study can be summarized as follows: 1. The cognition and satisfaction level of school forests supported by private organizations was higher than those by local governments. Therefore, the establishment of a post management system of private organizations is more effective than the simple financial support of local governments. 2. The frequency of use of school forests by residents was higher than that of teachers. Their purposes were mainly to rest or walk However, teachers used school forests for nature observation and education. 3. In a survey of teachers about a reform measure and problems of school forests, the necessity of a post management system and financial security were significant requests. In addition, steady publicity and education, participant program, and incentives for teachers should be considered. This study is meaningful to systematically develop and activate the school forest movement. The integrated approach to the school forest movement reflects opinions of related users and is expected to become a useful foundation in studying about the improvement of city environments.

Maritime accidents caused by a ship include collisions, sinking, stranding and fire etc. This study is intending to consider fire accidents among such diverse marine accidents. It is much likely that various sorts of fires break out because crewmen are living in a narrow space for long periods of time consequent on the ship's characteristic of sailing on the sea. According to the ship fire survey, about 50% of the total fire accidents occurred at an engine room, and the main fire origin was analyzed to be oil. In addition, ship fire breaks out in the order of baggage racks and living quarter. In short, the survey indicates that all sorts of fires belonging to A, B, C and D-class have occurred. This study, targeting an actual passenger ship 'A', found the response time to evacuation, during which the people on board a ship recognize the outbreak of fire, and act, and the travel time for evacuation which is the actual travel time. In addition, this study carried out a simulation through the special program for fire analysis - FDS (Fire Dynamics Simulator) in order to find the effective evacuation time, i.e. life survival time. Particularly, this study did comparative analysis of the influence on the survival of passengers and crew based on the collected simulation data by fire size and sort. As a result of the analysis, it was found that when examining the only actual evacuation movement time excepting the response time to evacuation, people are safe by completing evacuation before the effective evacuation time only in case fire size is 100Kw among all sorts of fires. In other words, in case of the outbreak of fire more than 1 MW, it was found to fail to meet evacuation safety regardless of fire size.

Maker activity, mainly practiced in informal or non-formal education environments activities, was expanded to the form of maker education' due to its various educational values and effects. Yet, one of the difficulties in practicing the maker education in school education is the lack of makerspace as a space for the maker activities. In this context, this study aimed to examine the process of how the students make the makerspace in their school and to define its educational effects defined as 'maker spirits.' For this purpose, this study developed a maker education program for 22 $10^{th}$ graders in an high school for 8 weeks who had participated in the project of 'Making Makerspace'. The results of the program were analyzed through data collected from reflective journals, interview, and observation journals. In conclusion, this study presented a practical and helpful way to make 'Makerspace' in school and at the same time, confirmed Maker education as constructivist learning environments re-encountered in the $21^{st}$ and as an alternative learning approach suitable for the $4^{th}$ Industrial Revolution Age.

Objectives : The purpose of this study was to investigate attitudes toward and practice of oral health management among adults in the Gumi area. Health behavior especially drinking and smoking have been proven to affect the tissues around the teeth and increasing in importance. Thus the study set out to examine oral management according to drinking and smoking to suggest a need for education about oral health and provide basic data for oral health education. Methods : Total 226 subjects, who consist of 141 male adults and 85 female adults, in Gumi were asked to fill out a self-administered questionnaire on October 24, 2009. Their answers to the items about general characteristics, health behavior, and oral health behavior were analyzed with the SPSS WIN 12.0 program. Results : 1. As for the frequency of visiting a dental clinic(hospital) for the last year, the non-movement group recorded higher frequency than the movement group, and the drinking group also did than the non-drinking group(p<0.05). 2. As for the experience and frequency of scaling, the female subjects were higher in the experience and frequency of scaling than their male counterparts. The older they got, the more they tended to have scaling. The married respondents had more experiences of scaling than the singles, and the non-drinking group was high in the experience of scaling(p<0.05). 3. As for the number, time, and method of toothbrushing a day, more women answered they brushed teeth three times or more per day than men; those who were in their forties were the highest in terms of the roll method, and those who were in their twenties were the highest in terms of toothbrushing time. The married group and the non-smoking group answered they brushed teeth in the roll method three times or more per day in higher percentage. And the non-drinking group was high in the roll method, which was statistically significant(p<0.05). 4. As for use and kinds of auxiliary oral hygiene devices, the female respondents used them more than their male counterparts. The older they became, the more they used them. The married group, the non-smoking group, and the non-drinking group used such devices a lot. The smoking group used dental floss most, and the non-smoking group used more kinds of such devices than the smoking group, which was statistically significant(p<0.05). Conclusion : Oral diseases can be prevented by adopting healthy and right oral management behavior. Using the findings of the study, more diverse programs about actual oral health education should be activated so that people can change their bad oral management and behavior and develop a habit of the right oral management attitude.

It is undeniable that IUU Fishing are threatening so many legal fishermen' economic livelihood, negatively impact on conservation and protection of the fishery stock and ecosystem itself. Especially, negative impact of IUU Fishing resulted from the increasing fishery activities on the high seas. The Korea case of Coastal and Off-shore Fisheries, difficulties in conserving and controlling the fishery stock was brought about. Simultaneously, it is the fact that there are so many damage such as the reduction of fish Stock management program's effect, dissatisfaction of legal fishermen, over-exploiting of fish stock. Related with this kind of problem, FAO had adopted "International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing(2001)". From this reason, Korea also needs to make actual efforts to prevent IUU Fishing. i.e. each nation should develop Korea action plan by Feb. 2004 and impliment it, report on implementation toward FAO. This Paper will review the definition of the IUU stipulated by "International Plan of Action on Illegal, Unreported and Unregulated Fishing" and study Korea cases of the IUU fishing. Finally, the analysis of Korea's implementation will be done, centering around the contents stated on the International Action Plan. The significance of this paper is to grope the political countermeasures against international movement of the IUU fishing prevention.
