As the quality of life has been improving, people are getting higher interest and higher expectation for safety. However, the accident rate at the construction site is still high. Therefore, it is urgent to secure the safety at the construction work. Due to the nature of the construction industry, construction sites are directly exposed to the external environment. The possibility of accident occurrence is increased due to various factors such as the always variable processes, the diversity of manpower input, the increase in vulnerable class, and the danger of construction equipment..Particularly, the disasters occurring at the small- or medium-sized construction sites (budget ≤ 12 billion KRW) account for 88.9% of the total disasters at construction sites (73.4% for casualty). It was due to the lack of management caused by the absence of supervisors and insufficient safety measures. Moreover, it is difficult for the small- or medium-sized construction sites to apply basic safety measures such as safety education and safety facility installation by themselves in order to prevent disasters because they don't have sufficient safety organizations. It is because they have relatively less safety personnel and poorer technology system than large-sized construction sites. Therefore, in order to reduce accidents in construction, it is necessary to prevent accidents at the small- and medium-sized construction sites. From this point of view, the objectives of this study were to identify the key risk items causing accidents frequently by analyzing the accidents at construction sites and identifying problems associated with safety management, and to secure the safety at the small- and medium-sized construction sites.

In order to cope with the decrease of construction manpower caused by the aging population and to improve construction productivity, Japanese Ministry of Land, Infrastructure, Transport and Tourism has been promoting construction methodology using ICT (Information & Communication Technology) since 2016. The ministry has established and implemented new cost estimation standards, delivery systems, and government support policies to boost automated earthwork using ICT, and is expanding the types of automated construction methodology applied at the construction sites. To utilize ICT at construction sites in Korea, as in case of Japan, laws, systems, and policies should be readjusted first. By comparing the ICT-related systems and policies between Japan and Korea, this paper scrutinizes critical benchmarking factors. As a result, we have reached the conclusion that in order to promote ICT methodology at Korean construction sites, Korean government should establish ICT-related cost estimation standards, delivery systems, and economic support policies in advance.

Recently, as the characteristics and production methods of the construction industry are changing, and women are actively entering the society, the view of women in the construction industry is also gradually changing. Although the government is currently improving the system to expand women's participation, nevertheless, women's participation in the construction industry is very low compared to other industries. The scope of this study was limited to presenting the actual working environment and improvement plans for male and female engineers in the design office. As a result of the survey on the insufficient part of the work environment, the item 'rest space such as lounge, bathroom, and conference room was narrow' was highly surveyed for men, and 'there was no rest space that required gender discrimination' was highly surveyed for women. As for the improvement measures, both men and women were surveyed highly in the category of 'My place for personal work'. In this study, the scope of the study has a limitation in that it only presents the actual situation and improvement measures for the working environment for male and female engineers in the design office.

The relationship between keywords, found in all productivity related papers published in the KSCE journal for last 15 years, were analyzed in order to reveal a research trend in the area using text mining and A-Priori algorithm. As the results, it is found that the word of 'productivity' is most closely related to the words of 'work' and 'labor'. Futhermore, the word is somewhat related to those of 'factor', 'model', simulation', and 'work time'. It is also revealed that, on the other hand, the words of 'machine' and 'equipment' have little relationships with the keyword. This research will be a great help for academia to understand a research trend in the area of construction productivity.

최근 기후변화의 영향으로 가뭄의 발생빈도 및 규모가 증가하고 있다. 이에 지자체를 중심으로 대체 수자원 확보를 목적으로 지하수의 개발이 늘어나고 있는 추세이다. 국내에서는 지하수 개발 이용시설로 관정(管井)을 활용하는 것이 일반적이나, 최근에는 낙도를 중심으로 대규모 지하수자원 확보를 위한 지하수댐 건설이 논의되고 있다. 현재 우리나라에는 6개의 지하수댐이 설치 운영되고 있는데, 가장 최근에 건설된 지하수댐도 20여 년이 지난 1998년에 건설되었다. 게다가 국내에 건설된 지하수댐은 지하수맥을 이용하기 보다는, 건천화된 시기에도 하천수를 이용하기 위해 하천의 지하에 건설되어 있어 일반적인 개념의 지하수댐이라고 보기 어렵다. 지하수댐의 활용을 통해 지하수자원을 효율적으로 확보하기 위해서는 첫째, 지하수에 대한 기초자료의 확보가 필요하다. 현재 지하수법 제5조에 따라 전국 지하수에 대한 기초조사를 실시하고 10년마다 보완조사를 실시하여야 한다. 그러나 1997년부터 실시되고 있는 기초조사는 예산 및 인력 부족 등으로 아직까지 전국 전체에 대한 자료가 마련되지 못하고 있으며, 보완조사는 아직까지 실시된 바가 없는 실정이다. 조속히 지하수 기초조사를 완료하여 전국에 대한 수문지질도(水文地質圖)를 작성하고, 이를 바탕으로 체계적인 지하수댐 조성계획을 수립할 필요가 있다. 둘째, 지하수댐 건설기술에 대한 체계적인 연구가 필요하다. 현재 조성된 하천 지하에 건설된 지하수댐이 아닌, 지하수맥을 이용하는 본래의 용도에 적합한 지하수댐을 건설하기 위한 세부기술의 확보가 필요해 보인다. 셋째, 현행 지하 충전수에 대한 수질기준을 확대할 필요가 있다. 현재 하수 폐수 및 온배수 재처리수로 지하수를 함양할 경우의 수질기준은 시 도지사가 관할 구역에 대하여 수립하는 '지역지하수관리계획'에 포함된 경우로만 되어 있어, 국가 또는 개인이 지하수를 함양할 경우에 적용되는 수질기준이 부재한 상태다. 또한 지하수 충전 깊이에 따라 토양에서 발생하는 정화능력에 차이가 있으므로, 수질기준에 차등을 두어 합리적으로 적용할 필요가 있다.

The cooperative relation between construction engineering firms and design subcontractors is essential to establish design collaboration system. So, this study is initiated with providing a strategic cooperation scheme between construction engineering firms and design subcontractors. A number of literatures related to the design process for engineering firms were reviewed in order to investigate the design collaboration system. A questionnaire survey was peformed to collect and analyze the expert opinion on the current design collaboration system for engineering firms. It is expected that the cooperation scheme can be utilized to improve the cooperative relation between construction engineering firms and design subcontractors.

Construction Research and Development (R & D) projects have been begun with the investment of 1.2 billions in 1994 and have been reached to 30 billions in 2004. During this ten-year period, a total of investment for construction R&D amounts to 125.7 billions (Total 418 construction R&D projects). However, the results of each R&D project could not apply to real construction site because each project has been performed by a small size (0.5 billions). In addition to those, the social interest on the construction R&D projects has not been received and those importance has not been recognized. Especially, there aren't still standardized methodologies or weighted measurement data for evaluating research performance of the construction R&D projects up to now. The construction R&D projects has been Invested on the basis of an annual technology demand survey rather than the research performance outcome. Therefore, it is important to establish a qualitative performance measurement model for evaluating construction R&D projects. This paper proposes a new research methodology for analyzing the performance measurement of the construction R&D projects. First of all, the Balanced Score Card (BSC) is used to evaluate the construction STAR technologies selected in this research. The performance items of BSC has been modified as four criteria such as "productivity, "knowledge accumulation," "training of students," and "welfare." The new research methodology developed in this paper is expected to use in establishing resonable construction R&D budget in the future.

By analyzing the operation status of fire safety management of small construction site workers, deriving problems, and suggesting improvement measures, this study was conducted to present practical basic data for their efficient use in the future, and the following conclusions were drawn. First, it was analyzed that small construction site workers are elderly in the age group of construction workers, have short construction skills, most of the jobs are working in the construction industry, and the employment type is non-regular workers. Second, the fire safety management improvement plan of small construction site workers is systematized, fire safety manager is deployed to manage fire risk, fire escape routes and emergency warning facilities are provided to inform all workers at the construction site. In addition, measures to reduce industrial accidents are needed through realistic evacuation training, fire VR training, and interesting educational programs.
