  • This study focuses on the evaluation of severity measures used for accidents associated with industrial machines and devices. In particular, duration of medical treatment, duration of work loss, number of deaths in an individual accident associated with industrial machines and devices are evaluated in various ways to assess the severity of the accident. The number of accidents with work loss of longer than 1 year as the severity measure and the number of accidents as the frequency measure appeared to be the most discriminating information and allow risk assessment based on these frequency and severity measures for grouping of industrial machines and devices. Results of such risk assessment further confirmed the re-classification of industrial machines and devices that are currently subject to safety certification (SC) and self-declaration of conformity (SDC) or selection of those machines and devices that are newly subject to SC and SDC.

  • 실내에서 보내는 시간이 증가함에 따라, 쾌적한 실내환경에 대한 요구가 증가되고 있다. 또한, 새집증후군과 같은 문제들에 관심이 집중되면서 실내공기질에 관한 요구 역시 증가되고 있다. 정부에서는 이러한 요구에 따라 실내환경을 관리하기 위하여 다양한 정책 및 제도를 제정하였으며, 공공건물에서의 친환경제도 인증을 필수화하였다. 실내공기질과 관련된 인증제도는 크게 3가지로 도면기반으로 인증을 평가하는 건강친화형 주택건설기준과 녹색건축인증 그리고 측정정보 기반으로 인증을 평가하는 실내공기질 인증이 있다. 이중 도면기반으로 인증을 평가는 제도들을 업무의 비중 대비 과도한 업무량이 요구된다. 친환경인증업무를 수행하는 한 회사의 인터뷰 결과 평균 업무비중보다 2배 이상의 소요시간이 필요한 것으로 조사되었다. 이는 2D기반의 작업환경에서 면적에 관한 정보들을 일일이 수작업으로 측정하여 필요이상의 업무를 수행하고 있기 때문으로 분석된다. 따라서 본 연구에서는 3D기반의 BIM모델을 이용한 실내공기질 평가 자동화 프로세스를 제시한다. 국제표준 포맷인 IFC 파일을 이용하여 필요한 면적정보 및 자재정보를 자동으로 추출하고 이를 모델에 적용하여 자동화하는 과정을 제시한다. 본 연구는 인증을 위해 필요한 업무시간을 단축하고 업무효율성을 높이는 것에 기여할 것으로 기대된다.

  • The purpose of this study is to extract environment-friendly planning elements to apply in Korea by putting together and reclassifying four foreign environment-friendly certification systems related to regeneration spaces - LEED in USA, CASBEE in Japan, BREEAM in England and BEAM in Hong Kong - and analyze and evaluate domestic and foreign spaces which were certified as Environment-friendly spaces in order to offer plan guidelines to raise awareness of the importance of environment-friendly elements in regeneration spaces and to encourage them. The concept and the characteristics of green building were studied through documentary survey. In addition, green certification system of the present domestic new spaces and foreign regeneration spaces was studied and assessment tools for indoor regenerated spaces-related green certification system were developed. With checklists which are developed in this study, level of going green of foreign spaces certified environment-friendly was assessed. Based on the results of this study, conclusions are as follows. As a result of case research of spaces-certified green of Hong-Kong's existing buildings with a developed checklist, application of general assessment part was all alike, but that of detailed assessment part was different. However, Hong Kong showed superiority in lighting energy saving, separate collection of recyclable domestic waste, recycling by-product and management. In addition, Hong Kong applied eco-friendly planning elements maintaining buildings in their condition as possible as it could with management, use of green program, replacement with high efficiency lighting, monitoring system, installation of recycling bins and energy saving by attaching reflective film.

  • This study was conducted to provide sustainable measures for conservation and management to protect valuable natural/ecological resources, offer differentiated quality assurance services for eco-tourism products, and explore measures for eco-tourism certification/designation systems. To achieve its goals, the study discussed domestic and overseas trends and literatures that concern eco-tourism certification/designation system and investigated case studies that were presently operational. A group of experts and a group of non-experts were surveyed separatedly to investigate the awareness of the national eco-tourism certification/designation system. The results from the investigation indicate that Europe, since the late 1990s to early 2000, has actively introduced a system that establishes and operates a dedicated institution, and European members have created a cooperation framework to formulate international partnerships and develop standardized assessment benchmarks to adhere to the goals of the system, the period for certification was designated from one year to five years, and renewals were granted based on periodic monitoring and reassessment. In Korea, from early 2000, the Ministry of Culture, Sorts and Tourism and other organizations have certified product quality and assessed travel products and national park tour programs. The certification period was established to be set between one and three years, and the vast majority were not reassessed. Upon investigating the results for awareness of national eco-tourism certification/designation system, a high number of respondents agreed with the need to establish a eco-tourism certification/designation system (90% of respondents), and the respondents cited eco-tourism quality assurance, conservation of value, means to maintain established institutions, and environmental education and information as reasons for needing a certification/designation system. In Korea, a certification/designation system for the eco-tourism industry is presently in operation, but the system regulates target institutions based on their characteristics. Therefore, this study proposes its suggestions via various categories, including designated institutions, designated purpose, designated subjects, designated organization, laws, regulations, and incentives.

  • Airworthiness authorities specify the technical standards of airworthiness that propose minimum requirement of the commercial transport category and apply the rules in the certification process to ensure the safety of the aircraft. The Federal Aviation Administration and other national airworthiness authorities define the fatal accident risk levels for the safety assessment of the aircraft system and establish standard procedures to apply both qualitative and quantitative analysis techniques. However, an accident or incident may occur by the combination of various factors, although the aircraft is designed in accordance with the strict standards and approval by the Airworthiness Authorities. There are some key factors, such as human error, unpredictable complex system failures, degradation of the components reliability, improper maintenance task and intervals. Risk can be reduced by reflecting aircraft operational experience with similar types of aircraft in the process of aircraft development and safety assessment. Result of the root cause analysis for the Airbus A300-600 incident in which the aircraft engine reverser was deployed in the air have been introduced to reflect the design of system and related components. Also, this paper suggests to create a big-database in order to provide a feed-back to the FAR Part 25 transport category design and safety assessment of the operational experience.

  • Recently due to the crisis of environment and resources, construction industry that effect a lot on nature than any other industries is essentially required to consider environmental element through the life cycle. Lots of advanced countries and Korea have already been running green building certification systems. However, GBCC(Green Building Certification Criteria) in Korea is lack of assessment criteria that apply environmental characteristics of tall building in compared with that in advanced countries. To improve the problem, we compared GBCC with LEED(Leadership in Energy and Environmental Design) through the case study. This study provides preliminary data for reflecting environmental characteristics of tall building in GBCC.
