Recent decrease in the availability of experienced skilled labor and a corresponding lack of new entrants has required the need for automating many of the construction equipment used in the construction industry. In particular, excavators are widely used throughout earthwork operations and automating its tasks enables work to be performed with higher productivity and safety. This paper introduces an optimal path generation method which is one of the core technologies required to make "Intelligent" excavators a reality. The method divides a given earthwork area into unit cells, identifies networks created by linking these cells, and identifies the optimal path an excavator should follow to minimize its total transportation costs. In addition, the method also accounts for drainage direction and path continuity to ensure that the generated path considers site specific conditions.

최근 기능 및 기술인력의 부족과 인건비 상승에 따른 공사비 증가에 능동적인 대처, 건설공사의 품질향상, 공기단축 등을 위하여 각종 건설공사 부분에서 합리화, 기계화가 활발히 진행되고 있다. 그러나 이러한 것들을 적용하기 위하여 개발된 신기술 혹은 신공법에 대한 건설기술자의 미숙지, 부적절한 시공, 무리한 적용 등의 다양한 원인이 결부되어 콘크리트구조물에서 균열발생이 발생되는 경우가 종종 발생되고 있다.(중략)

이른 새벽, 건설업 일용직 근로자들은 '오늘 일을 할 수 있을까?'란 불안감과 COVID-19의 감염 위험을 안고 인력사무소에 출근한다. 새벽 건설업 시장은 높은 업무 강도와 비효율적인 구인/구직 프로세스로 인해 진입장벽이 높고, 건설기능인력의 고령화로 불법체류 근로자 고용 등의 난항을 겪고 있다. 이에 따라 본 연구에서는 건설업 시장의 구인/구직 정보를 제공하여 앱 내에서 근로자 채용을 가능하게 하고, 외부 API를 사용하여 출퇴근 관리, 안전 이수증 촬영을 통한 인증 등 근로자와 구인자를 위한 비대면 구인/구직 앱 '인력거'를 개발하였다. '인력거' 앱을 통해 간소화된 구인/구직 프로세스 등을 통해 건설업에서 청년 일자리 증대가 기대된다.

Ever expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas plant construction have widely been discussed, because the plant construction has features of low competitiveness and high ripple effects when compared with other construction sectors. In this sense, the purpose of this research is to evaluate the CM capability of Korean construction industry for overseas plant construction. Fourteen construction business functions and four techniques were defined first. Based on these functions and techniques, CM capability was quantified for As-Is (2013), To-Be (2018) and Gap analyses. Findings of this research reveal that 1) capability for construction is quite competent, 2) capabilities for planning, design management, contracting, and risk management are found to be relatively low, where higher value can be added. In addition, it is found that R&D needs to be extended to develop systemized management techniques. It is also required to secure specialists and original technologies at national industrial level.

전력계통은 전력회사만이 갖고 있는 특유한 시스템으로써 우수한 계통해석 기술자를 양성하려면 그분야에 폭넓은 지식과 경험을 쌓아가는 것이 중요하며 이들에 대한 기술력의 향상은 전력회사 자신의 책임으로서 이를 위하여는 전력계통 시뮬레이터가 필수적인 수단이라 하겠다. 본 설비는 워낙 가격이 고가이고 전력계통 전분야에 활용이 기대되는 장비라는 점을 고려하여 설계단계에서 면밀한 검토가 수반되어야 할 것으로 생각되며 이를 위해서는 설비의 규모라든가 기본기능 설정에 있어서 국내의 학계, 산업체, 연구소 전문가들로 구성된 심의기구를 만들어 활용하는 방안이 효과적이라 생각된다. 또한 본 설비의 효과적 활용 및 운전을 위하여 [계통해석 그룹]과 같은 조직을 발족시켜 건설단계 부터 전문인력을 확보하고 건설후에는 그 조직을 [해석센터]로서 체제를 강화해나가는 방안이 고려될 수 있을것으로 판단된다.

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.

Currently, the construction industry is decreasing every year due to people's poor perception, high labor intensity, unstable employment structure, and welfare problems, as people avoid entry. Accordingly, this study investigated how to attract trainees and graduates from domestic construction education institutions to the construction industry. If institutional devices are prepared to prepare for the future by improving the welfare system such as unemployment benefits and retirement deductions in the construction industry, many trainees in their 20s and 30s will be attracted to the construction industry. If it helps expand hands-on education through on-site linkage and has the necessary technical skills for practice, it is believed that trainees and graduates in their 4s and 60s will be attracted to the construction industry.

Can examine cause that the construction industry is faced in crisis of skill exhaustion in two sides. One is the tribe of actuality production manpower by entry evasion and graying of young man class specially new manpower to the tribe of skill manpower. Another is qualitative decline of skill manpower. Generally, problem of the systematic knowledge tribe and the picking up tribe about new technology etc, exists because learn skill for shoulder beyond in spot. In cutting phenomenon of skill that is depended on personal relationships availability with skilled worker in hereafter, problem that worker who is old or enter through rain skilled worker does not learn all life skill is detected. These problems institute entry of young man class and necessity of systematic vocational education training specially new human strength strongly. This study does presentation of way to promote construction industry entry of young man class and improvement way of vocational education training system that can do to train these by function manpower by purpose.

This study proposes that a diving supervisor, who can perform the role of both a field manager and a supervisor, be introduced in the national qualification system. The goal was achieved by surveying the general status of the commercial diving sector, including the statistics of an underwater construction company, commercial diving equipment operation condition, diver working hours, diver supply and demand status, and underwater construction market size. The national qualification and national competency standard (NCS) systems were also analyzed to deduce the role definition and work scope of the diving supervisor. Consequently, the following proposition is made: the diving supervisor should be an "on-site manager with the highest job skill in the commercial diving field, who can perform the on-site process management as well as guide, supervise, and educate project participants and serve as an intermediary between the contractor and the workers." The responsibilities of the diving supervisor are proposed to include "diving planning and operation of the diving team," "diving with surface-supplied air and mixed-gas diving system," "chamber operation," "underwater construction," and "ship salvage." The persistent issues in commercial diving sectors, such as diver career development, management, and worker supervision, are expected to be largely resolved with the introduction of this qualification.

정부는 지난 10월 12일 "성장 고용 복지"의 선순환을 통해 우리 경제가 2020년까지 선진국으로의 도약 및 선진국 수준의 고용률 70% 목표 달성을 위한 국가고용전략을 발표하고, 이에 따른 5대 과제를 선정했다. 정부가 마련한 일자리 희망 5대 과제는 (1) "지역 기업"이 주도하는 일자리 창출 (2) 공정하고 역동적인 노동시장 구축 (3) 일 가정 양립 상용형 일자리 확대 (4) 생애 이모작 촉진 (5) 일을 통한 빈곤탈출 지원 등이다. 이번 국가고용전략에는 건설업 맞춤형 대책이 포함돼 건설업계도 적지 않은 변화를 가져올 전망이다. 고용노동부는"건설업에서 고질적 문제로 지적돼 온 과도한 노무비 삭감, 유보임금, 숙련기능인력 부족, 불법 외국인 근로자 사용 등에 대한 근본적인 개선방안을 마련할 방침"이며 특히 정부 발주 공사의 경우 근로자 노무비를 사전에 공사원가에 반영하는 방안을 협의 중에 있다.
