GHS는 위험물 분류와 운송부문에 관하여 물리 화학적 위험성과 급성독성의 분류와 표시사항을 기본으로 하여 기존의 UN시험방법과 큰 차이가 없으나 국내 기준인 위험물안전관리법의 위험물 판정 시험방법 및 분류체계와 달라 검토가 필요하다. 본 연구에서는 위험물안전관리법에 의해 분류된 제2류 가연성고체 물질과 제3류 자연발화성 물질 및 금수성물질을 대상으로 각각의 위험물 판정시험을 실행하였다. 시험 결과 GHS를 국내 실정에 맞게 적용하기 위해서는 각각의 판정 시험 결과를 통해 정확한 데이터를 확보하고 이를 통해 위험물안전관리법의 분류기준과 GHS에 따른 대응 분류기준을 제시함으로써 국제무역시 제도간의 규제 및 표지의 상이함을 통해 나타나는 문제점들을 예방할 수 있을 것이다.

Recently, the railway has been growing as the eco-friendly transport which is excellent for reducing carbon dioxide. However, the level of using tools to quantitatively and objectively evaluate the environmental performance is still low in the rail industry. Therefore, it is necessary to introduce Environmental Product Declaration(EPD) which describes the environmental performance by using Life Cycle Assessment(LCA) for evaluating the environmental impacts through entire life cycle of a product. The EPD enables stakeholders including policy makers, operation body, vehicle manufacturers and drivers and consumers to be informed about the superior environmental performance of rail vehicles.

The Product Carbon Footprint Labeling has been run for more than four years by the Ministry of Environment and there are number of products labeled by KEITI(Korea Environmental Industry & Technology Institute), as for declaring products with their carbon emission during life cycle stages. There are several categories for certifying products by the characteristics of usage. Building products which are applied to a building as combined components or elements, are classified as production goods which means that the products are chosen by a business, not by a final consumer. In this paper, current status of PCF labeling has been reviewed focused on building products and the characteristics of carbon emission by a kind of product such as interior products, window products, structural products, system products and others. Until Dec. 2013, 82 products has been labeled and it covers about 53% among labeled product goods by the certification. Among the labeled building products, interior products are main products. From the results of comparison, variations of emission amounts by products have been found and the cause of variation could be explained by the purpose and material properties of products. However, the exact reason for variations cannot be acquired because of lack of information and the short operation period of the certification program. Further studies and more products are needed to be studied and analyzed focused on the emission characteristic by each product and to suggest reduction technologies for sustainable building products.

This paper intends to analyze the roles of regulations and certifications within the construction market that affect the effective recycling and application methods of construction waterproofing industries. Certifications, eco-labels, green certification patents, and new excellent technologies obtained in construction waterproofing industries are studied. In accordance to the study results, it was determined that, a total of 38 items obtained eco-labels with effective recycling as the theme, 10 items with green certifications, and 8 items with New Excellent Technologies. Regarding the types of effective recycled resources, most of them were concerned with composite-polymer(EVA, PVC, etc.) materials, waste tire powder, waste rubber, etc., which indicated that there is a clear limitation in the variety of the materials that are eligible for effective recycling in the construction waterproofing industries.

Recent international environmental regulations are focused on reducing pre-contamination and on sustainable development prior to the usage stage of a product. The Environmental Performance Declaration is being used as a tool for quantifying the environmental performance of products, to reduce contamination in advance, and for advertising the results of railway vehicles in Europe. In this study, a life cycle assessment of the tilting train was conducted, the first such case study in Korea, according to the ISO 14025 standard and Korea EDP (Environmental Declaration of the Product) rule. As a result of the LCA, the life cycle carbon emission of the tilting train was determined to be $3.54{\times}10^7kgCO_2eq.$ which is higher than that of a European train. Also, the amount of $CO_2$ emission of the Mcp and car body is higher than that of the other car and bogie.

Equipments that can transmit maritime distress signals in accordance to Global Maritime Distress Safety System are the followings: A1 water(Very High Frequency, SART), A2 water(MF/HF Radio Equipment), A3 water(INMARSAT), A4 water(Emergency Position Indicating Radio Beacon). Institutions with the capacity to receive distress signals are Korea Coast Guard affiliated radio stations, patrol ships, Rescue Coordination centers, Vessel Traffic centers, Complex problems regarding repetitive distress alarms, inaccurate statistics, multiple control towers are existent. Consequently, effective measurement to resolve dispersed operating maritime distress signal system are in time of need. Moreover, current KCG Headquarter is considering to integrate five distress radio stations dispersed across nation into a single international safety communication center. The integration of radio stations are efficient in terms of information coordination between nations, however, it cannot support efficient response to real-time maritime incident. Therefore, in this study, a new system that can rapidly response to real-time maritime incident will be proposed.

Recently, in the concrete industry, the development and commercialization of low-carbon products of ready-mixed concrete have emerged as part of the efforts to realize carbon neutrality. This study aims to investigate the current status of environmental product declaration(EPD) of ready-mixed concrete and to analyze the characteristics of carbon emissions by compressive strength, life cycle stage, and region. To this end, the related certification system requiring the calculation of carbon emissions in the concrete industry was analyzed. The target of analyzing the current status of carbon emissions was set as a product of ready-mixed concrete that acquired EPD certification based on the life cycle assessment method. In addition, the trend of carbon emissions according to each characteristic was reviewed by analyzing carbon emissions by the life cycle of ready-mixed concrete products, analyzing carbon emissions by standard, and analyzing carbon emissions by region. As a result, the carbon emissions in the pre-production stage were 99% compared to total carbon emissions., and as it increased from 18MPa to 40MPa, carbon emissions also increased. Even with the same specifications, the carbon emissions in the capital region were higher than in the southern region.

After empirically investigating the vehicle accident risks by age groups, various programs and policies have been imposed to reduce the old's risks in other countries. In Korea, it is little known the risk level by age groups and no policy changes has been implemented even if the number of vehicle accidents occurred by the old has been rapidly rising while the total number of vehicle accidents has been decreasing. This study empirically investigates the vehicle accident risks by age groups and the results show that the old drivers over age 65 has the highest accident risk except for the young drivers below age 25. Thus, we emphasize the necessity of reinforcing the qualifications for reissuing the drive licence and programs for educating the old drivers in Korea which is facing the most rapid population aging in the world. On the other hand, various changes are needed reflecting the old drivers such as reforming the road signs, issuing a sticker and providing them incentives such that the old drivers use the public transportation instead of self-driving.

LED(Light Emitting Diodes)는 반도체를 이용한 발광소자로서 동화상 광고물이나 가변정보표지판(VMS)등에 주로 활용되고 있으며 최근 외국의 경우 LED 기술을 교통신호등에 적용하여 시범설치 및 확대 적용 설치하여 운영 중에 있으며 국내에서는 산업체, 학계, 연구소 등에서 연구 개발 중에 있다. 본 연구는 현재 이러한 산 학 연의 노력에 의해 개발된 LED 교통신호등을 현장에 적용하기에 앞서서 실내실험과 현장실험을 통하여 에너지 절감효과 및 현장적용성을 검증하고 경제성 분석을 통한 타당성을 제시하는 데 목적이 있다. 연구 내용으로써 기존 전구식 신호등과 LED 신호등의 발광원리 및 특징 비교 분석, 실내실험을 통한 에너지 절감효과 검증, LED 보행자 신호등 현장적용성 평가, LED 신호등으로 서울시의 기존 신호등을 연차적으로 교체하는 경우에 대한 경제적 분석이 실시되었다. 실내실험을 통해 LED 신호등의 에너지 절감효과가 평균 76% 임을 검증하였고 보행자 신호등에 대한 현장 실험에서 설문응답자의 83.7%가 LED 신호등의 시인성이 우월하다고 나타나 현장적용성은 긍정적인 것으로 나타났다. LED 신호등에 대한 경제성 분석결과 자본회수기간은 6년으로 나타났으며 향후 기존 신호등의 고장 및 유지 보수 등에 의한 차량정체 비용, 교통사고 비용 및 소자기술 발전을 고려하면 이보다 단축될 것으로 판단된다. 향후 차량등에 대한 운전자들의 반응 및 장기적인 안정성 등에 대한 종합적인 실험이 추가적으로 이뤄져야 할 것이며 이를 바탕으로 하여 LED 신호등에 대한 규격서 제정 등 법 제도 측면이 이루어진 후 LED 국내 기술 수준 등을 총체적으로 고려하여 LED 교통신호등에 대한 보급방안이 강구되어야 할 것이다.
