In terms of protective engineering, there are no noticeable researches regarding covered-positions for smaller units in South Korea. So, standards to maintain and build protective facilities for larger units have been applied in ones for smaller units without any adjustment. The previous study was to calculate penetration depth of the concrete walls because the experiment performed indoor. In this outdoor experiment, velocity of projectile impact as one of the other important factors was considered to prove the validity of 30cm concrete wall thickness as effective protective level of the covered-position. Random effects and extraneous variables which could be occurred in outdoors experiment were controlled with statistical techniques. As a result, velocity of projectile impact was significant variable and the given standard, 30cm thickness of concrete walls was as valid as ever.

The opinion on merits and defects caused the unified-closed of a school facilities have collected by a people and government since the unified-closed system was enforced. There is a problem that the data occurring in the middle of the unified-closed is not analized. Therefore, in this study the target is elementary schools in kyung-gi province which did the unified-closed. First, this study is for analysing which condition influenced to make them. Second, it is for understanding the problems occurred in the process of the unified-closed and presenting the direction of improvement. Third, it is for setting up the planned guide by classification of school facility for the unified-closed which considers the previous problems sufficiently. The range of the study treats of general trend and analysis about the unified-closed of elementary school. The core subject is to analyse the standard and classification of the unified-closed of the object school by the policy of the unified-closed and to compare the carried process of the case school.

As children are known to touch and chew everything, green cleaning procedures are an important step in preventing children from ingesting harmful toxins. The objectives of this study are to develop a new, self-evaluation checklist and to suggest design recommendations which comply with easy, adaptable, economical ways to improve the eco-friendly indoor environment of Korean childcare facilities. The information compiled during this study was collected through literature review and internet surveys1) from July, 2009 to February, 2010. The results of this study show that the current Korean childcare accreditation system and practices emphasize clean building interiors, policies for sanitation and cleanliness, and control of humidity and lighting. On the other hand, the information provided by green-building rating systems from GBCC, LEED, and GBTool offers additional and comparative details regarding indoor environment quality and standards regarding the IAQ performance and management plan, ventilation and thermal comfort systems, views from windows, acoustics, and lighting. In conclusion, this document provides an appropriate and easy-to-follow, self-evaluation checklist composed of eight criteria and 51 practical items. This study also provides the design recommendations composed of 27 practical ideas focusing on interior elements. Both the checklist and design recommendations I have suggested can be a post-occupancy tool for evaluating eco-healthy facility standards as well as tips for continuing to maintain eco-healthy childcare facilities.

In Article 311 of the Regulation on Occupational Safety and Health Standards requires the use of Korean Industrial Standards Act in accordance with the Industrial Standardization Act. However, the classification, inspection, maintenance, design, selection, and installation of explosion hazard locations for explosion and explosion prevention and internalization of 'safety' in the performance maintenance phase of electrical machinery and equipment There is no technical and institutional management plan for remodeling and alteration. Analysis of actual conditions and problems related to the installation, use, and maintenance of explosion-proof equipment, comparative analysis of domestic and international technical standards and systems, technical, institutional and administrative systems and systems related to installation, use, and maintenance of explosion-proof equipment, technical personnel and qualifications, etc. It is to propose legislation, system improvement, and technical standard establishment related to the maintenance of explosion-proof facility performance through improvement of the necessity and feasibility study for establishment of the legal status of the management site and management plan. As technical measures, KS standard revision (draft), KOSHA guide (draft) and explosion-proof facility performance maintenance manual were presented. In addition, the institutional management plan proposed the revised rule on occupational safety and health standards, the revised rule on the restriction of employment of hazardous work, and the manpower training program related to the maintenance of explosion-proof facilities and the qualification plan. Enhance safety at the installation, use, and maintenance stage of explosion-proof structured electrical machinery. It is expected to be used to classify explosion hazards, select related equipment, and to update and standardize standards related to installation, use and maintenance.

국내외 철도터널 방재기준들에서 특히 주목할 만한 것은 신속한 대피를 위해 많은 비용이 소요되는 대피통로 설치 기준을 강화 적용하고 있다는 점인데, 국내 기준의 경우 1km 이상 연장의 터널별 QRA 분석을 통해 위험수준에 따라 설치여부를 결정하도록 하고 있으나, QRA 분석에 필요한 화재발생확률, 화재발생 시나리오, 화재규모, 사회적 위험도 평가기준 등에 대한 세부적용기준들이 정립되어 있지 않음으로써 과다설계로 인한 사회적 추가비용이 발생할 수도 있으므로 이에 대한 적정 수준의 기준 정립이 필요하다. 이에 본 연구에서는 관련문헌 조사 분석을 통해 합리적이고 적정한 수준의 세부적용조건들을 선정하여 서로 다른 터널연장을 가진 모델 터널(고속철도용)들에 대한 QRA 분석과 동시에, 중요 대피촉진시설중 하나인 대피통로 미적용 가능한 터널최대연장에 대해 분석하였다. 또한, 현재 호남고속철도 등 터널들에 대한 QRA 결과와 모델 터널의 분석결과를 종합, 피난촉진시설 관련 국내외 기준들과의 비교를 통해 적용기준의 적정성 검토를 수행하였다. 이들 결과들은 향후 안전성과 경제성이 고려된 합리적인 방재계획 수립을 위한 기초자료로써 활용될 수 있을 것으로 기대한다.

This study was carried out to determine traffic noise level and analyze noise reduction effects of various sound protection facilities in the area of Seoul, Inch'on, Songchoo and Seoul- Busan Expressway from March to Octover, 1987. The results were as follows; 1. As compared with the environmental standards and the traffic noise level in heavy noise areas, traffic noise levels observed were shown in higher than environmental standards. The noise levels in Seoul were determined at 12.8-18.2 dB(A) in daytime and 19.0-26.9 dB (A) in nighttime. And incase of inch'on, it were 6.7-9.6 dB(A) in daytime, 7.9-18.9 dB(A) in nighttime, respectively. 2. The environmental noise level observed in the backside of protection facilities, such as apartment, soundproof barrier and houses, which were constructed in paralled to the road was lower about 3-5 dB(A) than perpendicular to theroad. Noise recuction effect of upper stairs in apartment was higher than lower stairs. 3. The predicted noise level obtained from the equation $({\triangle}L\;=\; -10\;log\;(^{I'1}/Ii)\;was\;\pm\;1dB$ (A) and the correlation coefficient (r) was 0.923. 4. The noise reduction effect in backside of apartment was measured at on sites and predicted by total noise loss equation. The predicted noise level was 60.9 dB(A) and the measured level was 60.6 dB(A), respectively. 5. The narrow width landscape less than 10m width was almost no effect for the protection of traffic noise. According to the synthesis of the above results, the noise level of the road was exceeding mostly the environmental standard in the heavy traffic areas. The counterplan should be set as well. The insulation of noise protection facilities were effective by the location with near distance from the road edge. The reduction effect of double window in apartment was represented so much. The prediction model could be applied to estimate the noise levels in the roadside as well as the effectiveness for the noise protection facilities.
