  • The Rural Housing Standard Plans for improving the quality of life and housing stability in rural areas has been developed 87 types from 1994 to 2012. However, some types of Plans do not satisfy the current legal standard in accordance with social and legal changes. Standard plans has the same effect as a building permit, and replace it, so legal suitability of Plans is an important. Therefore, it is required the suitability analysis on the legal standards of Rural Housing Standard Plans. The Purpose of this study is to derive improper types and items of the Rural Housing Standard Plans on the legal standards. In this study, we analyzed its suitability on the legal standards(law on fire-fighting system installation and safety management, energy saving design criteria for buildings, structural checklist for small buildings, the types of drawing for building permit) in accordance with "rules for the operation of standard plans". And we analyzed the utilization of the Rural Housing Standard Plans through downloads from welchon portal.

  • With the development of industrial technology and science, production and manufacturing facilities have been enhanced and improved, and the importance of the safety of workers has also been regulated and limited by various safety management methods. As a way to secure the safety of the workers from the production facility, the fail-safe and fool-proof methods are now being applied. Any possible insecure behavior and unsafe conditions can be removed by adopting the standards and specifications that are now secure the safety of workers and equipment. This research analyzes EN ISO 13849-1 international and European standards during CE certification. In order to secure acceptable reduced risks, the risk assessment process of ISO 12100 and the processes for reducing its risk are applied. In the current ISO 13849-1 standard, the criteria for the required performance level PLr (Required Performance Level) for the applicable risk and safety functions through the risk assessment are subjective and not subdivided. Therefore, the evaluation criteria are likely to cause judge's judgement error due to qualitative judgement. This research focuses on evaluation and acceptable performance level setting for the safety circuit of the equipment. We propose an objective and specific evaluation criteria to secure safety, and the proposed evaluation criteria are applied to the case study of the safety circuit for the equipment. In order to secure the safety of the entire safety circuit, the improvement of the MTTFd and DC level related to the SRP/CS (Safety-Related Parts of Control Systems)' lifetime is required for the future research.

  • The building section is providing immediate causes for global climate change problems since it takes about 50% of carbon emission, 20~50% of waste discharge, 33% of energy consumption, 40% of resource use, and 17% of water consumption. So, many countries over the world have developed and implemented green building certification systems to assess sustainable performances of buildings since the early 1990s. In korea, the green building certification system to induce the diffusion of sustainable buildings was first introduced in 2002 and developed as an improved version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013 after major revisions of related legislations. This research conducts a survey targeting residents on an apartment building that was certified as green building and examines the importance of assessment criteria on apartment buildings to certify green buildings using the Analytic Hierarchy Process(AHP) method. And it proposes a new direction on certification assessment standards from the resident's prospective. As a result, assessment criteria such as indoor environment, ecological environment, energy & environment pollution, and maintenance management among 7 main ones turned out important on assessing the G-SEED system for apartment buildings, while criteria such as material & resource, water circulation management, and land use & transportation did relatively unimportant.

  • G-SEED aims for establishing green environmental building with energy saving and has started for evaluating with multi-residential complex in 2002 by the Ministry of Land, Infrastructure & Transport (MOLIT) and the Ministry of Environment to develop the current 10 building types and new & existing building types to be applied. Since G-SEED has been developed for more than 10 years, the strategy of globalization is needed with constant review itself and comparison between other assessments to understand current situation from the global perspectives. This study draws similarities and differences of G-SEED and LEED criteria by the comparison from re-constructed LEED criteria based on G-SEED. "Energy & Pollution" is the most concerned category in both assessments as the result of analysis on category rates. Next concerns are "Material & Resources", "Indoor Environment" and "Water Management". The unique categories in both criteria are "Ecological Environment" in G-SEED and "Innovation & Design Process" in LEED. The conclusion of this research is that two assessments are organized at different locations and with different strategies for developing green building but there are common concerns such as energy saving, material use, indoor environment. As a result, it is expected to use fundamental data for developing G-SEED for global standard.

  • The G-SEED encourages the installation of new and renewable energy facilities through assessments of the new and renewable energy installation rates. The government also regulates the installation rate of new and renewable energy facilities in the 'Project on new and renewable energy obligation in public installations'. The current criteria concerning the new and renewable energy facilities in the G-SEED are the result of an amendment made in July 2010. As over five years have passed since this amendment, the assessment criteria needs to be reenforced. To improve the current criteria, the calculation results of the installation rate of new and renewable energy facilities in the G-SEED were analyzed and compared to the corresponding calculation results of the 'Project on new and renewable energy obligation in public installations'. And an improved draft for the assessment criteria of the new and renewable energy facilities in the G-SEED was proposed.

  • 최근 총톤수 16만 톤급 이상의 대형 크루즈선이 국내 항에 정기입항하고 있다. 크루즈를 이용한 국내 관광객이 증가함에 따라 정부에서는 크루즈산업 활성화를 위해 항만기반시설 확충에 많은 노력을 하고 있다. 현재 국내 주요 항구에서 크루즈전용부두 공사가 진행되고 있다. 그러나 국내 항만 및 어항설계기준에는 크루즈선 및 접안시설에 대한 표준제원이 제시되어있지 않다. 대상선박의 표준제원이 제시되어있지 않아 전용시설물 설계 및 인허가에 많은 어려움이 예상된다. 그래서 본 연구에서는 크루즈선에 대한 표준제원을 제시하기 위하여 현재 운항중인 크루즈선의 톤수별 대표선형의 제원을 분석하고 PIANC 사례 및 국내 항설기준을 비교분석 하였다. 분석결과 크루즈선은 연안여객선과 선박제원 및 선박조종성능에 차이가 있음을 알 수 있었다. 따라서 크루즈 전용시설물 설계를 위해서는 반드시 대상선박의 제원이 국내항설기준에 반드시 포함되어야 한다. 그리고 선박의 범위를 산정하기 위하여 크루즈선 평균제원 값에 커버율(75%)을 적용하여 크루즈선 표준제원과 수역시설물에 대한 기준을 제시하였다.

  • The purpose of this study is to grasp the effectiveness of evacuation safety design by verifying the appropriateness of the standard of occupant load factor for residential buildings. To this end, the definition and current standard of occupant load factor for residential buildings were analyzed, and the problems of the current standard were clarified by interviewing professionals. In addition, changes in occupant load factor were examined by year based on statistical research, and evaluation on the current standard $18.6m^2/pers.$ was performed. As for evaluation methods, the need of redesigning of evacuation capacity was investigated by using evacuation simulation. As a result of the analysis, the most serious problem was clarification of the applicable standard for residential officetel, where the average occupant load factor was $26.1m^2/pers.$, which was not appropriate. However, as a result of evaluation on evacuation capacity, although there was no difference between statistical research results and the current standard in terms of evacuation capacity, when the standard for business facilities was applied to officetel, evacuation time doubled. Thus, this study suggests that when the current standard is applied to residential officetel, it is necessary to separate between residential use and business use.

  • Purpose: The ramp is an important facility for the barrier free access and vertical circulation of users of various buildings, including users of walker, wheelchair users, stroller users, and baggage carriers. The installation standards for ramps in Korea have various problems during construction and BF certification. It is necessary to improve the criteria for ensuring practical mobility and safety. Method: Korean standard, International Standard(ISO 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(OENORM B 1600, 2017), Swiss Standard(Norm SIA 500, 2009), Canadian Standard(Building Standards Guide, 2017), American Standard(ADA Standards, 2010) were investigated and analyzed. A comprehensive improvement of the ramp installation standards is proposed. Results: The ramp is a necessary facility for the barrier free access and vertical circulation of the disabled. It shall be installed with comprehensive consideration of the appropriate slope of the ramp, the distance of the continuous slope, the handle and upstand for pedestrian safety. In order to improve convenience, setting the proper slope and limiting the length of the slope are very important, and improvements are required to the levels presented by international and foreign standards. The unclear standards of Korean law and BF certification standards should be clearly improved so as not to be misinterpreted in construction and Barrier Free Certification. Implication: International and foreign standards should be reviewed to ensure practical mobility and safety. And comprehensive improvement measures should be presented through continuous research.
