This study is aimed at utilizing LCA processor with BIM LOD, eliciting the problems of the existing environmental assessment by constructing the database for environmental values of green buildings. For these objects, environmental load database of BIM construction material and evaluation process are presented, after matching BIM family based environmental load database which is available during evaluation stage, input-output tables and Korea LCI database to standard item code of public procurement service. It is a important factor in environmental assessment of building to develop database unit of standard item code for BIM and construction material. Thus, the results of this study are expected to provide basic data for improving effectiveness of construction through BIM based environmental load evaluation database. Furthermore, the provided environmental load database unit for construction material is considered to be available as basic information for BIM study by suggesting a processor connecting BIM with LCA and along with this, continuous examination on the connection process is needed.

플랜트 산업은 2004년도 기준 해외 건설 수주액의 70%를 차지하는 매우 중요한 산업이다. 플랜트 산업은 E(Engineering), P(Procurement), C(Construction) 산업이라고 불리며 국내 플랜트 산업의 기술력은 일부 시설관련 상세설계와 시공부문의 경쟁력을 확보한 상태이다. 그러나 플랜트 산업의 E, P, C 가운데 고부가가치 창출이 가능한 E부문의 기획, 기본설계 기술이 미흡하여 기술력 향상이 필요하다. 따라서 고부가가치 창출이 가능한 기획, 기본설계 기술경쟁력을 향상시키기 위하여 플랜트 설계를 위한 표준코드활용상의 문제점을 분석하고, 이에 대한 개선방안을 제시하고자 한다.

Generally, a lot of reinforcements are used in nuclear power plant concrete structures, and it may cause several potential problems when concrete is poured. Because of the congestion caused by hooked bars, embedded materials, and other reinforcements, it is too difficult to pour concrete into structural member joint area. The purpose of this study is to change ACI 349 Code for using the large-size(57mm) and high-strength(Gr.80) headed deformed bars instead of standard hooked bars in nuclear power plant concrete structures in order to solve the congestion problems.

In this research, a new methodology to perform building energy analysis using Industry Foundation Classes (IFC) standard has been studied. With the help of Archicad 14 modeling software, a 3D test model is generated and then exported to IFCXML format. A ruby code program retrieves the building information from the resulting IFCXML file using Nokogiri library. An INP file is created and gets ready for next energy analysis step. DOE 2.2 program analyzes the INP file and gives a detailed report of the energy cost of the building. Case study shows when using the IFC standard method, the Interoperability of the energy analysis is greatly improved. The main stream 3D building modeling software supports IFC standard. DOE 2.2 is able to read the INP file generated by IFC file. This means almost any 3D model created by main stream modeling software can be analyze in terms of energy cost Thus, IFC based energy analysis method has a promising future. With the development and application of IFC standard, designers can do more complex and easy-to-run energy analysis in a more efficient way.

With the rise of BIM application and green building assessment, studies on assessment of CO₂ emissions from buildings using BIM are needed. In accordance with the requirements, this study aims at developing BIM Template database, as a part of development of CO₂ assessment technology using BIM. Based on the research of construction materials, this study develops database by applying Procurement Agency Item Code to BIM Template. The results of this research makes it possible to assess CO₂ emissions of materials with BIM Template and building data modeling implementation.

This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

본 연구의 목적은 과거 14년간 한국 정부가 투자한 연구시설 장비의 구축정보를 기반으로 기초 분석과학 분야에서 중국산 연구시설 장비가 국내연구장비 시장에서 차지하는 규모와 시장점유의 수준을 알아보기 위해 구축년도 장비표준분류 보유기관 유형별로 구축 수와 구축금액 차이를 비교 분석하였다. 또한 구축년도 장비표준분류 보유기관 유형 변수들 간에 상관성 유무도 분석하였다. 2019년 1월 1일을 기준으로 2005년부터 2018년까지 국내에 구축된 중국산 연구시설 장비를 대상으로 기초 분석과학 분야에 활용되는 연구시설 장비(구축금액이 3천만원 이상인 주장비 기준) 50점의 구축 수, 구축금액, 구축년도, 연구장비 보유기관, 그리고 장비표준분류를 분석 항목에 포함하였다. 구축년도 장비표준분류 보유기관 유형 내 중국산 연구시설 장비 구축 수 차이를 비교하기 위하여 단일표본 카이제곱검정 방법을, 구축년도 장비표준분류 보유기관 유형별 중국산 연구시설 장비 구축금액 차이를 비교하기 위하여 각각 맨-휘트니 U 검정과 크러스칼-왈리스 검정을 사용하였으며 구축년도 장비표준분류 보유기관 유형 간 상관성 유무는 교차분석을 통한 카이제곱검정을 이용하였다. 본 연구결과, 중국산 연구장비의 국내 구축 수와 금액은 구축년도 장비표준분류 보유기관 유형별로 통계학적으로 유의하게 증가(p<.05).하는 추세이며 2000년대에 비해 2010년대에 고가의 광학전자/영상장비가 사립대학 및 민간기업과 정부출연연구소에 구축되었다. 따라서 기초 분석과학 분야 내 중국산 연구시설 장비의 국내 구축현황은 국산보다는 그 수준이 아직 미비하지만 구축 수와 금액이 통계학적으로 유의하게 증가 추세이므로 중국산 연구시설 장비가 국내 연구산업시장을 잠식할 수 있다는 가능성을 인지함과 동시에 관련 대비책 마련이 정부 주도로 필요할 것이다.

Recently Korea has imported and executed Performance Based Design for the method to settle the dangerousness on outbreak of fire of high-rise building. The overseas country's PBD is autonomic but It is unable to carry out the essential role of PBD as the performance based design that based the code based design in the domestic. Also It occurs the problems that different the classification standard of building as dualisation between the building code and the fire services act. In this study, We have investigated overseas's cases for the PBD of high-rise building and have drawn the improvement direction & the problem of domestic's PBD by comparing and the analysing the domestic regulation.

After 1th line was built in 1974, the history of subway in Korea has been expended to 9th line which is under construction. It is time to prepare nation wide subway grounding system urgently according to the domestic electric standard that aligns to world wide standard by WTO/TBT treat (1995). Newly added grounding system to the fundamentally different system caused many problems. PSD(platform screen door) and other newly added equipment are also need grounding system. By the electrical code(established by Korea Electric Association), low voltage equipment(including grounding system) under 1,000V AC are in the process of change into IEC 60374. IEC 60364 standard will be added to the electrical code(established by Korea Electric Association) in 2007 and amended and after 3-5 years later, it will become a complete IEC 60364. So the purpose of this study is to compare the domestic rail road grounding system and suggest the standardized grounding system for the newly built subway.
