The objectives of this study is analysis of the characteristics of fire risk and survey of narrow dwelling space(the Karaoke, Gosiwon etc). The narrow dwelling space has special structure characteristics; the narrow and the complex escape rote. Gosiwon have very separate and exclusive space room, so have the problem a suppression of fire. Furthermore almost Karaokes located in basement have a complex and limitary escape rote. Therefore we should research and development the exploration equipment that search a source of the fire and a emergency rescuer in the scene of the fire.

The present article reports the results of a basic study for improving the fire safety of postpartum care centers. In the case of postnatal care center facilities, newborn babies and mothers reside 24 hours a day, and as they are located in high-rise and multi-use facilities, measures for fire safety are necessary, but there are no domestic manuals. This study examined the problems of fire safety through an analysis of fire cases of postpartum care facilities and related regulations, and conducted surveys on the fire safety consciousness of employees and mothers regarding postpartum care management. The fire safety consciousness of the mother was analyzed.

지구온난화에 따른 우리나라 주변 환경의 변화와 최근 중국 불법 어선의 연근해 어업 자원의 고갈 등으로 인해 우리나라 연근해 어족자원을 보호할 필요성이 증대되고 있으며, 지속 가능한 어업을 위해서는 어획물의 종류와 양을 정확히 파악하고 불법 어업에 대한 철저한 감시 및 관리가 필요하다. 이러한 시공간적으로 다양하게 변하는 생태 및 어장 환경 정보와 선박에 대한 정보를 통해 해양관측과 위성 원격탐사를 동시에 이용함으로써 근해와 원양 생물자원 실태를 관측하는 것이 가능하다. 본 연구에서는 NOAA-20 위성의 VIIRS (Visible Infrared Imaging Radiometer Suite) DNB (Day & Night Band) 영상을 기반으로 추정한 야간 불빛 자료를 활용하고자 한다. DNB 불빛 영상은 낮은 조도의 불빛을 감지하여 그 정보를 보여 준다. 야간 불빛 자료에 포함된 구름 부분을 마스킹하기 위해 NASA의 신규알고리즘이 적용된JPSS-JRR-CloudMask 기술을 이용하였다. 이번 연구에서는 구름의 영향이 없는 날짜를 선별한 후 AIS 정보에서 어선의 정보를 추출하여 검증 자료로 사용하였다. 실제 선박의 정보를 이용한 위성 불빛 자료의 검증을 통해 위성자료의 신뢰성을 확보하고 향후 불빛과 선단 규모의 상관관계 분석 및 어선의 분포 경향 분석을 통하여 우리나라의 어장환경 분석에 활용 가능할 것으로 기대한다.

This research investigates into overall oral health status of adolescent girl inmates in a juvenile detention facility and ordinary school students in the same age range of 11 to 18 years old and compares the results focusing on the difference between the two groups. The last 5 years dental records for girl inmates in Juvenile detention facility and for students who have visited the Department of Pediatric Dentistry at Ajou University Hospital was colleted and analyzed. The restorative treatments took up the greatest part in their history of treatments. While the percentage of extractions of permanent teeth due to dental caries had been gradually increased, in Juvenile detention facility students, throughout the transition period from middle school to high school, in dental hospital patients, the phenomenon of the same kind has hardly been detected. After that record analysis, oral examination for Juvenile detention facility students and dental hospital patients was conducted. DMFT index for dental hospital patients are 4.15, whereas, the value for Juvenile detention facility students are as twice as high to be 7.53.

This study sets out to examine training courses for newly government-employed librarian for developing training contents to learn their basic knowledge, and suggests development model about training contents' planning, designing and making-process. In addition, in order to evaluate cyber training contents it devises self-evaluating tool, conducts a reviewing of questionnaire and measure by Delphi method. The final content made under the cyber contents development model proposes the six areas and 28th trials. Feasibility assessment for the purpose of evaluating educational contents, based on 17 questions to measure the factor analysis results, it yields, it yields 4 factors having more than .40 variance. Though differences in perception depending on factors did not show statistical significance, the difference in the adequacy of questions results significantly lower in some of them.

In apartment project, BCWS is a critical management factor and has a great influence on the success of the project. But due to the characteristics of large apartment complex, there are several problems in making out a time schedule of work as well as production and management of precise bcws from the allocation of resources. In this study, Actual condition survey was executed in terms of the calculation and the management of BCWS. This study propose better solutions for efficient calculation of bcsw through the analysis of the problems and the origins relating to BCWS from a field area.

To improve the quality of dwelling environment of domestic apartment house, it is required to establish the sound insulation standard and the performance evaluation method which is suitable to the domestic residential conditions. In this study, the properties of internal noisy sources of a single unit in apartment houses and the sound insulation performance of party walls are investigated and analyzed, as a primary step to the establishment of sound insulation standard. Based on these data, the differences in sound insulation index of each plane type are investigated along with their causes. Also, the factor which affect and decide the insulation performance are analyzed in an effort to improve the performance of party wall structures.

The rate of wearing glasses in 248 young Korean people of 20 to 30 years of age were investigated. The study had findings such as below: 1. The rate of wearing glasses was (73.8%). 2. The rate of first time glass wear occurred mostly in 14-16 age group (31.7%). 3. The duration of glasses change rate was of 6 month to 1 year of wear (40.4%). 4. The glasses purchase price was between 50,000 to 60,000 won (37.1%). 5. Choice to purchase the glasses was made mostly by oneself (85.8%). 6. The factors subjects considered in making the choice of purchase was face types and hairstyle (56.3%). 7. The subjects'satisfaction level of eyesight examination in optical stores was 51.5%.
