Recently, large APT complexes are newly constructed in Taegu city and among them, large APT complexes aggegate densly espically in Weolsung and Jisan complexes of Dalsuh-gu and Susung-gu districts. The purpose of this thesis is to perform occupants' apprasials about residential environment on the housewifes residing at new constructed APT who seem tn have different apprasials on the residential environment by the zones. The results of the investigations are as follows. 1. House possessed type and house sire got elevated in comparison with them before shifting residence in respect to residential property and it was revealed they moved to short distance in the change of their lands. And most occupants could choose their houses by looting-out and there's some difference in the choice motive according to the zones. 2. As a result of studying the relation between demographic and residential properties, there were deep differe-nces in the Possessed house type before move, possessed house size after move, preferenti-al degree of house and move plan. 3. In the degree of satisfaction on residential environment, the result was high in the order of heating facilities, water-supply and draining facilities and lighting and was low in the order of room's size, interior decoration and soundproofin. According to zones, there was a great difference in the items of room's size, privacy, heating facilities, securi-ty from calamity, ventilation, convenience of traffic and school group and facilities for extracurricular activities and the degree of satisfaction was high in Jisan zone in othe items except for room's size and heating facilities. 4. In the tenants' apprasials on tile inside and outside spaces of the zones, important factors were "Cultural Institutions", "Green Areas", "Level of Welfare Facilities" and "Utility degree of welfare facilities" and in the classification of important factors according to the zones, the first and the third factors were changed each other. I think this is because they attached importance to somethings dissatisfied in present circumstances.

The method of operating a game could determine the psychological distance between the player and the game character, and thus, in the Virtual Reality, players' control methodologies are important to enhance their immersion. This study has the objective of examining the difference in games according to the method of operation based on the player's movements. This study researched the effect of the method of operating movement conforming to the movement of the character and the physical operation of the body on forming game experiences for the player. The result of performing an experiment increased reality for the game player through a controller in the shape of the actual control, to increase focus in the game. As so, game play through movements, including actual movements by the player displayed to enhance game satisfaction. In the part of media remediation field, Game can be defined as media which has their own unique hypermediacy. Especially, in the motion based game, players' movement mediates players and the game, therefore, players' movement could make players' experience augmented or immediate in accordance with the characteristics of movements. Even though sports and dances genres of motion-based games are common, RPG or adventure genres are rare. It can be explained that the characteristics of the action have been explained in the immediacy. In a game of fantasy, which is difficult to experience in real-life situations, the nature of the player's motion can increase the immersion of the game, which can contribute to utilization of players' motion and experience design in the various genres and suggestion of grounds theory. In addition, through this study, it is able to design motion-based games of various genres.

This study is to suggest some developmental policies by analyzing the activities of first aid party in Kwangju and Chonnam regions for two years from Jan. 1, 1991 to the end of December, 1995. First, the residents in Kwangju and Chonnam regions have the sufficient benefits of emergency medical center, but it will be desirable that general hospital should be established and managed in Kohung peninsula which forms the wide island area far away from big cities. Second, the classification of the degree of severe case in the field by rescue members should be strengthened as the means which can reduce the number of patients transferred to the emergency room and the legal method which rescue members can select the medical agency. Third, children less than 10 are most frequent emergent patients and it is due to parent's indifference and children's in sensibility to safety. So the safely education in the course of infant and elementary education should be strengthened and the method which can keep the self safety through the legal system. Fourth, to increase the rate of emergency measure by rescue members, the reasons of fail of emergency treatment are suggested, the treatment results of each rescue member are analyzed every year and it is desirable that the system which can evaluate the personal ability should be introduced. Fifth, the medical accidents occurred in the case of medical act, by rescue members must lake the legal responsibility, but such a problem can he solved with the compensation of insurance system by government. Sixth, to reduce the time required for transfer, traveling service system for the fixed period in beach should be complemented and extended more and service system at ordinary times should be examined at mountains, the area of traffic jams and large special industrial park. Seventh, since service system with one team of two members of 119 rescue party in expressway cannot be mobilized when multiple accidents occur at the same time, it is considered that service system of two teams of four members should be extended. Eighth, first-aid service in expressway is conducted with rescue and emergency treatment by the rescue party at the same time, but the professional rescue lacks and it may result in the injury of patients. Therefore the creation of rescue party in expressway is the urgent problem.

Background: The epidemiology of nasal fractures varies according to factors such as the era and area of the study, as well as the age of the patient. We compared the characteristics and causes of pediatric nasal fractures. Methods: A total of 2,321 patients with nasal fractures from 2010 to 2017 were examined. The patients were divided into age groups using the Korean school system of age classification. The causes of injury were divided into five groups: violence, fall or slip down, sports, road traffic accidents, and others. Fractures were classified using the Stranc and Robertson standard: vector of force and plane of fracture. Results: Violence was the most common cause of nasal fracture in patients older than 12 years. Violence was a significantly less frequent cause among patients younger than 12 years old than among adolescent and adult patients. Nasal fractures due to violence were not observed in patients younger than 10 years. Plane 2 and lateral force fractures were the most common; however, in patients younger than 12 years, frontal force fractures were significantly more frequent than were lateral force fractures. Conclusion: As children may simply be injured due to a fall or slip down, it is important for the parents and guardians to ensure their safety. As they become older, children should abstain from violence and be monitored. It is therefore very important to ensure that the environment is free of violence in order to prevent such injuries.
