Recently automated construction system is attended in construction domains because of the increase of aged workers and the shortage of the experienced. So, the proportion of automated construction in Korea is expected to be getting higher from partially automated robots to full automation systems. However, it is difficult for the automated system to operate flexibly like the human based on various work condition. In the result, the higher the level of automation in the system is, the less efficient the automated system work in the site. So, it's necessary the development component design to compensate for the flexibility shortage of the system. Therefore, this study proposes the development process to component design suitable for automated construction system using QFD technique.

The success of construction projects is heavily dependent on the work ability of the field managers who manage the execution of projects. The work ability of field managers is influenced by various elements such as job stress and individual characteristics. The purpose of this study is to reveal the factors influencing the work ability of construction field managers in Korea. Work ability is evaluated bases on the Work Ability Index(WAI) developed by the Finnish Institute of Occupational Health, while job stress is measured using the Korean Occupational Stress Questionnaire Short Form developed by the Korean Occupational Safety & Health Agency. The results showed that field managers under higher job stress have lower work abilities. In addition, it is revealed that exercise or religious practice have a positive influence on work ability. This study will help to increase the work ability and enable the efficient management of organization at building construction sites.

For this study, a series of interviews with engineers in the Korean construction industry was carried out through a formal workshop format to analyze the causes of the inferior quality of builders' hardware. The authors established the causes of defects in window hardware construction in relation to the three aspects of system, design, and construction as involving the following seven factors: lack of system (including low ability to create construction specifications); low social awareness of the importance of window hardware; low technical capability to create design drawings; low design costs; small manufacturing capacity; low construction cost; and short duration of construction. Among the seven causes, the biggest cause of defects in window hardware construction is the lack of a system (low ability to create construction specifications), followed by low technical capability to create design drawings. In addition, this study carried out basic research to create measures to prevent defects in window hardware construction by analyzing how such causes of defects are distributed depending on the scale of architectural firms and construction companies during actual projects.

과거의 대학교육이 교수 중심의 공급자 중심이었다고 한다면 미래의 교육은 수요자 중심의 교육, 즉 학생 중심의 교육이 되어야 한다는 논의가 무성하다. 또한 교육과정을 이수하고 졸업한 학생을 채용하는 기업이 바라는 교육의 내용이 무엇인지를 아는 것은 매우 중요하며 공학인증제도의 도입노력과 연관된다. 즉 회사가 채용한 대학 졸업생의 실력을 통하여 대학의 교육성과를 최종수요자인 회사가 평가하여 그 결과를 대학의 교육과정에 피드백하는 것이 공-학인증제도의 취지이다. 그러므로 회사가 원하는 졸업생의 능력을 갖추도록 대학교육의 커리큘럼을 구성하는 것이 바람직하고 그렇지 못한 대학은 채용에 있어서 불이익을 받을 것이다.

Unlike conventional building materials, the living building material (LBM) cube is composed of sand, gelatin, and cyanobacteria without cement. The surface of the LBM cube absorbs CO2 from the atmosphere by photosynthesis and is deposited in the form of CaCO3. In addition, the crystals generated in this process strengthened the gelatin-sand structure to enhance the compressive strength.

This research will focus on the public agencies, designers, supervisors, building cooperation, and contractor who involved in urban development plan. By understanding the complexity and the priorities in urban development process, all problems of the urban development projects can be solved or improved. These priorities are specified using AHP (Analytic Hierarchy Process). A questionnaire survey is employed to identify the problems of urban development process and the methods of revitalizing urban in this research. Through the survey, 35 issues are drawn out. Factor analysis technique is applied to extract the underlying interrelationships possibly existing. Using latent root criterion and varimax rotation method, 9 factors are extracted(by using 34 issues after deleting 1 issue less than 0.4 of factor loading) These 9 factors named as PIF (Problem Improvement Factor) consist of integration estimation (PIF1), cooperation operation capability (PIF2), contractor corporation capability (PIF3), capital for infrastructure investment (PIF4), misunderstanding of effective land use (PIF5), financial capability (PIF6), obscure goal of project (PIF7), shortage of cooperation expertise (PIFS), administrative procedures (PIF9). PIF 6 is the most important factor and PIF 1 is the most widely effective factor to succeed urban land development projects. It is recognized that administrative office is most responsible for PIF1 cooperation is most responsible for PIF2, 7, 8 and 9; contractors is most responsible for PIF3 and PIF6; administrative agencies is most responsible for PIF4; cooperation and consultants are responsible for PIF5. From findings in this study, some suggestions are proposed for the revitalization methods of urban development projects through the land readjustment method.

전기공사는 전기공사업법에 의거 전기공사업을 등록한 자에게 발주하여야 하며 도급받은 공사업자는 전기공사업법, 전기설비기술기준, 설계도서에 적합하게 시공하도록 하고 있지만, 일부 발주관서에서 전기공사를 정보통신공사업 등 다른 공사업종으로 발주하는 사례가 있어 관계법령에 의한 전기수용신청에 애로 요인이 될뿐 만 아니라 전문적인 시공능력이 결여된 자에게 시공을 의뢰할 경우 부실을 초래하여 국민의 생명과 재산에 심각한 위협이 되고 있는바, 이와 같은 폐해를 사전에 예방하고 전기공사의 설계 및 적법한 시공업체를 선정할 수 있도록 기본적인 방향을 제시하고자 한다.

도시화로 인한 홍수 피해 및 비점오염원 저감 방안의 해법으로 정부부처 및 지자체에서는 LID 시설의 설치를 권장하고 있다. 국토부 산하 GI&LID연구단 및 관계 부처의 노력으로 국내 LID 기술의 도입 및 연구 개발이 활발히 이루어지고 있으며 우리나라 환경에 맞는 LID 시공 기술력을 확보하는 중이다. 하지만 비점오염 및 홍수 저감의 대안으로서 LID 기술은 각광받고 있으나 LID설치 비용의 과대 인식과 실효성에 대한 불안감이 만연하여 시설 설치에 어려움을 겪고 있다. 본 연구에서는 도심지내 LID 기술을 적극적으로 도입하여 단지 조성중에 있는 송산그린시티 친환경시범마을을 대상으로 시설 설치 비용에 따른 비용 편익을 분석하였다. 시설 설치전 불투수면적에서의 물순환 관리능력과 설치 후 투수 및 저류 능력의 확대에 따른 물순환 관리능력을 비교하였고, 일정 수치 이상의 물순환 관리능력을 갖기 위해서 시설 설치에 필요한 비용을 분석하였다. 금번 연구에서 분석한 모델링 결과는 추후 준공될 친환경시범마을의 실제 관측치와 비교하여 연구 실효성에 대한 분석을 수행할 예정이다. 본 연구를 통해 LID 시설 설치시 비용-편익을 분석하고 이점을 제시하여 추후 있을 LID 시공 및 관련 연구에 도움이 되고자 한다.
