Purpose: As the improvement in quality of medical environment and the spatial consideration for the prevention of infection in the hospital have become increasingly important in the recent years, specific and practical planning for air conditioning room's area has become a major issue accordingly. However, the air conditioning room tends to be discussed focusing on technical factors such as air conditioning systems that are irrelevant to building plans, while discussions of most departments related to the medical functions have actively taken placed. Therefore, this study aims to investigate the factors influencing the planning for the air conditioning room area, and through subsequent analysis of the area of the air conditioning room, to propose a way to improve effective planning for the air conditioning room area. Methods: This study examines the case hospitals that fall into two types: each floor supply system and concentrated supply system, and compares and analyzes the air conditioning room area-related factors and the characteristics of changes in the interior of air conditioning room before and after remodeling through air conditioning floor plan of those case hospitals. Results: The air conditioning room can be classified into the net area of the functional space such as duct passages, and the public area such as aisle space, and of those the public area is an important factor in calculating the area of the air conditioning room. The public area of the air-conditioning room should not be planned considering only the spaces for mobile passage or maintenance activities, but should be planned taking into account internal changes such as expansion and replacement of equipment in the future from the beginning. Implications: When planning a medical facility, it is used as basic data for the planning of the air conditioning room area, which is a significant fixed factor in the initial setting.

PURPOSE: This study was conducted to investigate the effect of the virtual reality training (VRT) using 3-dimensional video gaming technology on spatiotemporal gait parameters in older adults. METHODS: The study participants were divided into two groups: the VRT group and the control group. Those in the VRT group were enrolled in a VRT, which was conducted for 60 min per day, two times a week, during the 6-week research. The Wii-Fit balance board game was used for the VRT intervention. The VRT consisted of 6 different types of games, namely, jogging, swordplay, ski jump, hula hoop, tennis, and step dance. A 3-dimensional TV was used for 3-dimensional display. Participants in both the groups received 3 sessions of fall prevention education, at the first, third, and fifth weeks. Their gait parameters were measured by using OptoGait. RESULTS: After 6 weeks of the VRT, the spatial gait parameters of the participants, that is stride length and step length, were significantly improved compared with those of the control group participants (p<0.05). The temporal gait parameters, such as velocity, cadence, stride time, and step time, also showed improvement after the completion of the VRT training (p<0.05). Both the temporal and spatial gait parameters of the VRT group participants showed improvement after 6 weeks of the program compared with those of the control group participants (p<0.05). CONCLUSION: The VRT using 3-dimensional video gaming technology might be beneficial for improving gait parameters to prevent falls among older adults.

Objectives: This study aimed to investigate the seasonal variation in stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions. Methods: 226 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from November 2005 to October 2006. The year was subdivided into four parts: spring (March-May); summer (June-August); fall (September-November); and winter (December-February). Stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions in the four groups were examined. Results: Ischemic stroke was most frequent in summer, whereas hemorrhagic stroke was most frequent in winter. There was no significant difference in seasonal variation of stroke. The frequency of ischemic heart disease among stroke risk factors was significantly high in spring (p=0.031). The frequency of hypertension, diabetes mellitus, atrial fibrillation, and hyperlipidemia did not differ among seasons. There was no significant difference in Sasang constitution among seasons. Frequency of small vessel occlusion was highest in summer. Large artery atherosclerosis was frequent in spring and summer,but seasonal variation of ischemic stroke subtypes did not show statistical difference. Conclusion: Acute stroke demonstrates seasonal characteristics according to stroke types, ischemic stroke subtypes, risk factors for stroke, and Sasang constitutions. These results have important clinical implications in stroke prevention.

Objective : Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. Methods : We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery). Results : Among all the 2617 THI patients, total number of pediatric patients was 256. The average age of the subjects was 9.07 (standard deviation${\pm}6.3$) years old. The male-to female ratio was 1.87 to 1 and male dominance increases with age. The most common cause for trauma were falls and traffic accidents. Age (p=0.007), surgery (p<0.001), mechanism of trauma (p=0.016), subdural hemorrhage (SDH) (p<0.001), diffuse axonal injury (DAI) (p<0.001) were statistically significant associated with severe brain injury. Conclusion : Falls were the most common cause of trauma, and age, surgery, mechanism of trauma, SDH, DAI increased with injury severity. There is a critical need for effective fall and traffic accidents prevention strategies for children, and we should give attention to these predicting factors for more effective care.

Rats and Cockroaches are the most problematic pests of our living environment, Rats generally fall under three categories, namely, the Norway rats, the roof rats and the mouses, Among these three types, the roof rats are increasing rapidly in number and their habitats are spreading quickly in the city area, where as the Norway rats are decreasing both in number and habitat. There are numerous damages that these pests create in our society, The rat induce damages to computers and other information processing equipments, sometimes cause light-out, and other financial losses and other sanitary problems. The cockroaches, apart from inducing serious sanitary problems, is an insect that creates insectophobia. decently, it has been revealed that cockroaches are also the main carriers of allergic diseases. Among the pesticides employed against rats in Korea, Beta - fluoro acetate(1080) was initially used after the National Liberalization. Later, the Korean government imported anticoagulant rodenticide for its control. This was followed by a brief, unsuccessful utilization of Zinc Phosphide. Since the begin of 1980s, with the advent of pest control companies, first generation anticoagulant rodenticide were developed in Korea and recently followed by a widespread use of pesticide that utilizes second generation anticoagulant material, the "Brodifacoum" . Among insecticides employed against cockroaches, "Fenitrothion" "Dusban" "DDVP" "Diazinon" and others have been used. They were gradually being replaced by the use of synthesised pyrethroid insecticides until recently. Today there is a wide spread use of bait poisons, the "hydramethylnon" Nevertheless, full prevention and control can not be realized with the sole use of the pesticides. In the future, hygine and proofing, combined with affective pest management, must be incorporated in order to bring about more satisfactory and fruitful preventive measures.

The necessity for the investigation of death occurred in military services has no differences to the death of civilians. But the death of military service members under the Universal Conscription System in Korea has special considerations because of hard accessibility by the bereaved family and closed environment of the army. The analysis of the death occurred during military service was carried out and the advanced death investigation system to prevent the death was proposed to prevent the declination of fighting spirit and efficiency and also to restore the solid support by the people. The deaths in the period 1995~2006 were 330 persons in 1995, 359 persons in 1996 and were decreased to 135 persons in 2006. The death caused by safety accidents including vehicle accident, drowning, fall were 56% and by military crimes including suicide, arms, homicide were 44%. The numbers of suicides were 108 persons in 1995 and were decreased to 79 persons in 2006. The numbers of suicides were decreased constantly, but the ratio of suicide to death were increased, so the suicide prevention is more important. The autopsy ratio was increased to 51.5% in 2005 and was much higher compared to the ratio for civilians. The main reasons of complaints by the bereaved family were for regaining reputation, death in harness and reinvestigation of death. The proposals for the advanced death investigation system were as follows. The unnatural deaths including the obvious accidental deaths and homicides have to be defined by the rules. The human resources to perform the autopsy can be supported by the forensic pathologists from medical school. The special training and quality assurance programs are needed for the crime scene investigator. To regain the impaired reputation from the suicide and to support the bereaved family has to be discussed by the government.

Recently in most homes, children are mostly cared in early childhood education facilities. However, the increased number of safety accidents on children cared in such facilities has become a social issue. For that, the purpose of this study is to suggest interior environmental planning elements to improve safety level of early childhood education facilities. This study was carried out by performing literature review analysis and survey. First, in total of 42 environmental planning elements that can be applied domestically were derived from analyzing safety related guidelines for children facilities located both domestically and internationally then a survey was carried out targeted for teachers and staffs in the facilities on importance of the factors. The results of this study are as followings. First, it is required to intensify the level of safety related training for teachers and staffs in the facilities including better treatment for them. Second, the necessity of safety environment by each space in such facilities is required to be approached upon the level of child activities. Third, facilities planning and finalizing planning are important for improving safety of early childhood education facilities. Forth, from factor analysis on the extracted environmental planning elements that are considered as important by the teachers from both day care centers and kindergartens, they were categorized in 5 groups including 'collision and fall prevention plan', 'physical characteristic consideration plan', 'evacuation safety plan', 'lock security plan' and 'outer control plan'. It is fair to say that constructing a better safety environment for children can be achieved by the environmental planning factors by this study.

토석류는 사면 붕괴, 산사태, 홍수 등과 같은 인명 및 재산피해를 수반하는 자연재해의 일종이다. 2006년 7월 집중호우로 인하여 대규모 토석류가 발생하였으며, 이에 따라 고속국도, 일반국도, 철도 등의 국가 기간망이 통제되어 언론에 보도되는 사태가 발생하곤 하였다. 토석류에 대한 연구는 지금까지 충실히 수행되지 않은 것이 사실이다. 원인으로는 예측이 매우 어려웠을 뿐 아니라, 발생위치가 산지에서 주로 발생하였으며 도심지 및 주택가에서 발생하지 않아 국민들에게 부각되지 않았던 이유도 있다. 본 연구에서는 토석류를 방지하기 위하여 사방댐 등의 대책방안이 수립되어 적용되어 오고 있으나, 단점 및 보완점을 개발하여 새로운 기법을 적용하였다. 또한, 계곡부의 특성 및 형상에 따라 다단계의 유연성 시설물을 설치함하여 인명 및 재산피해를 최소화 할 수 있도록 고안하였다. 대상지역을 2개소 선정하여 적용성에 대한 평가를 실시하고 결과를 제시하였다. 연구결과, Site A, B 지역에 토석류 방지시설이 각각 17개와 13개가 설치요구되었다. 향후 토석류에 대한 체계적인 지침 및 방안에 대하여 정립해 나갈 필요가 있을 것으로 생각된다.
