  • 최근 이산화탄소배출 감축과 환경오염 물질 저감이 세계적인 이슈가 됨에 따라 규제를 강화하고 있다. 수송 부분에서는 사용 연료를 기존 화석 연료에서 수소 등 친환경 연료로 에너지 전환이 이루어지고 있다. 국내에서는 에너지 전환에 발맞춰 2040년까지 1,200기의 수소 충전소 구축을 목표로 하고 있어, 넓은 인화 범위를 가지는 고압 수소를 공급하는 충전소의 안전성 확보가 매우 중요하다. 본 논문에서는 충전소 사고 발생 시 충전소 내 근로자의 안전확보를 위해 국내 기준과 일본, 유럽 등의 수소 충전소 안전거리 기준 현황을 분석하여 안전거리 설정 가이드 라인을 제시하였다. 안전거리 설정 절차는 유럽의 EIGA 기준에 따라 설비별 사고 발생빈도와 TNO의 EFFECTS 소프트웨어를 활용한 피해 영향 분석을 통해 사망 확률이 3.5E-05 이하가 되는 안전거리를 산출하였다.

  • In 1990s, interest on Environment has been increased and Environment-oriented consumer's economic power accelerated the trend of preference for 'Environment-friendly material'. Moreover, the concept of 'Sick Building' Syndrome has been spread to the public and solution for the syndrome is required. 'Environment-friendly material'means that the material used is not harmful for the user's health, and on top of that, causes least harm to the environment during production/scrap process of the material itself. Decision of designers and architectures, as a result, is really crucial tot he environment issues. Above all, selecting the most environment-friendly material and design among possible candidates is natural and cost saving way. In the paper, couple of Evaluation Criterium for Material Selection are analyzed and objective linkage has been identified. With the result of analysis, methodology to minimize damage on environment during whole life cycle of the Interior Design has been sought for.

  • Since the 20th century, it has been the most important agenda that issued the environment of earth. And it has been enormous endeavors for providing the environmental-friendly. It has now outcome as a policy of estimate and acknowledgement for providing the environmental-friendly. Regarding that is the most efficient method in a practical sense, the policy has rapidly been developed. This study is an attempt to categorize interior design of the policy. Thus main-body of this study shall be clarified the definition of the notion of the environmental-friendly design and investigated the element of harm against the environmental-friendly as well. Eventually the conclusion is to provide a guideline for the environmental-friendly especially for the field of interior design materials, by the investigation of the exiting policy for the environmental-friendly design.

  • This study is to develop teaching aids in the area of Clothing and Textiles based on cooperative learning as an alternative to increase the quality of Home Economics class. It is very difficult to control students because of noise coming from activities. when teachers teach students with cooperative learning strategy a classroom with restricted space. Sometimes the activities will disturb other classes in the school. which will harm the real purpose of cooperative learning. However. we have more positive results from cooperative learning method. because students have more chance to improve their personal skills. easily solve a problem together and openly express their opinions. Moreover. we found that they understand the subjects and increase their attention much better because they are tested right after learning. We anticipate that the developed teaching aids will be a great help to improve middle school Home Economics class.

  • Air pollution in subway tunnel is primarily caused from the wear of metallic materials. As undesirable substance, PM(Particulate Matter) can especially harm the health of passengers and workers as well as clog the main parts of rolling stock such as inverters. To improve the air quality in subway tunnel, SMRT(Seoul Metropolitan Rapid Transit Corporation) has developed anti-pollution devices such as Magnetic Dust Collector, Vacuum Cleaner For Rail Road and Particulate Removing Sprinkler Vehicle. Introducing these mechanical devices, this paper is mainly devoted to explaining the characteristics of collected dust according to the result of particle-size analysis and componential analysis.

  • 지하철 역사 특성상 천장내 시설물의 잦은 교체, 증설, 점검 등에 따른 시설물의 지지철물(강-앙카) 설치와 천장내부 작업자의 이동 등으로 천장마감재의 훼손 및 콘크리트 구조물의 피해가 우려되고 공사비 증가의 요인이 되고 있다. 또한 공사중 발생되는 소음, 진동, 미세분진 등으로 역사 이용환경이 저해되고 민원이 발생하여 공사관리에 어려움이 있다. 따라서 천장시설물의 지지철물 시공방법을 개선하여 작업의 편리성, 경제성, 효율성 등을 고려한 천장틀 시공방법을 제시코자 한다.

  • Conserving clean air and removing contaminants and particular matters accumulated in the ventilation system of the subway stations are key issue for green railway environment. There is no national guideline or industrial regulations to sustain clean duct and ventilation system, which requires rapid reformation of cleaning procedure and system. In fact, accumulated various particular matters and dusts can occur secondary air contamination and become a primary health harm factor for subway passengers. This study investigates various duct cleaning technologies and trends. In additon, effective cleaning method with an automated robot device is proposed. In particular, current dust cleaning technologies and duct cleaning robots are analyzed based on their functions and feasibilities. The proposed design of automated device is expected to save the operating cost of subway HVAC system and sustain clean air environment.

  • Purpose: Education provided in many Korean medical colleges still isn't free from the contents of the "2+4 year program." Korean medical colleges especially holds onto the belief that humanities must be taught to the lower grades. Methods: I introduced the six-year integrated program and reversed the order of the existing education program. The new program assigned anatomy, physiology, and biochemistry to the 1st years, and humanities subjects such as forensic medicine and medical ethics to the 4th, 5th, and 6th years. Results: Increased participation and interests among students. Conclusion: Occupational and Environmental Medicine (OEM) at the level of pre-medicine brings harm rather than good.

  • Dosan Seowon, one of the earliest and most prestigious private Confucian academies in Korea, is an example of a heritage property citizens wish to sustain for the benefit of future generations. It is recognized of its contribution to the Korean society and as an architectural and historical interest. This study conducts architectural and cultural research about Dosan Seowon by scrutinizing its evidential, historical, aesthetic and spatial values. By doing so, it is possible to recognize how appreciated qualities are vulnerable to harm through only understanding their heritage values without practical management solutions. That understanding should then provide the basis for developing and implementing management strategies (including maintenance, cyclical renewal and repair) that will best sustain the heritage values in a physical aspect. The conclusion suggests that communication about Dosan Seowon among those who are concerened is significant.

  • Recently, for places with poor vegetating environment, such as slopes made of weathered soil or rocks, erosion tranquilizers, coverings and composite fertilizers have been mixed with seeds and sprinkled onto soil. Also, these plant revegetations have been mixed with nets and used to strengthen cohesion. However, this technique often obstructed plant growth and caused pollution because of not decomposing nets. This study has tested influence on plant revegetation B for slope of weathered soil and rocks and decomposition of naturally decomposing polyester filament yarn. In result, it was showed that plant revegetation B does not harm environment in case of applying it to soil slope and enhance protection capacity of slopes as time goes by. Also, naturally decomposing polyester filament yam was analyzed its physical properties with the passage of time and was known that naturally decomposing polyester filament yarn transformed into a structure easy to decompose by hardening. Thus it is considered that the revegetation method used this study was very effective method for plant establishment and stability of slope.
