This study is to investigate the possibility of legislation that is the foundation of school complexation project and the architectural planning for the target facility as stipulated by related law. Since 2000, many schools have been established and operated in the whole of Korea, mainly in Seoul. However, on the frontline, there is still a lot of difficulty in carrying out the project due to the legal possibility related to the school complexation and the lack of understanding about the facility for school complexation as stipulated by the law. The purpose of this study is to present the possibility of the school complexation project based on related laws and to clarify the classifications of school complexation facilities which are stipulated by the related law, and to propose the foundation for the future school complexation project. The contents of this study were investigated through the literature survey on the theoretical review and related laws of school complexation, and various laws related to school complexation were classified based on this, and the possibility of school complexification prescribed by each law was analyzed. In addition, by classifying facilities subject to school complexation prescribed by the Act and analyzing the detailed standards stipulated in relevant laws for each facility, we propose the facilities that can be combined with school facilities, and utilize the data of this study.

최근 국내 건설산업에는 생산성 저하, 기능 인력 유입 부족, 품질 저하, 안전사고 증대 우려 등 다양한 문제점들이 나타남에 따라, 이를 해결하기 위한 대안으로 Off-Site Construction (OSC)이 주목을 받고 있다. 그에 따라, 건설 프로젝트의 주체들은 기존의 현장 타설 공법뿐만 아니라, OSC의 도입 또한 하나의 대안으로 고려를 하고 있다. OSC의 도입은 초기 단계에서의 의사결정이 매우 중요함에도 불구하고, 합리적인 의사 결정을 위한 방법론이 부족한 실정이다. 본 연구에서는 프로젝트 특성을 도출하여 그에 대한 공사 난이도 지수를 선정하고 각 공법별 cost model을 개발하여 표준 공사비를 산정하여 최종 공사비 점수를 도출하는 의사 결정 시스템을 개발하였다. 본 연구에서 개발한 의사 결정 시스템을 활용하여 초기 단계에서 OSC 공법의 효율적인 도입을 위한 의사 결정을 할 수 있을 것으로 기대한다.

최근 SW융합인재 양성을 위한 비전공자 대상의 SW교육에 관심이 높아지고 있다. 국내는 SW중심대학을 필두로 전공과 상관없이 모든 학생들에게 SW를 기초교육으로 필수화하는 추세이다. 본 논문은 프로그래밍 수업 사례를 통해 SW 전공자와 비전공자, 비전공자의 경우 인문 계열과 이공 계열의 차이가 프로그래밍 학습 능력과 느끼는 어려움에 연관을 보이는 지를 학업 성취도 분석과 설문 및 개인 상담을 통해 살펴보았다. 그 결과 전공에 따른 학업 성취도엔 유의미한 차이를 보이지 않았으나, 인문 계열이 이공 계열보다 실습, 과제, 팀프로젝트와 같은 실제 프로그램 구현에 대한 체감 난이도는 높게 분석됐다. 상담 결과로 프로그래밍 문제 자체에 대한 이해 부족, 학습과 과제에 도움을 줄 수 있는 친구나 튜터와의 관계 부족, 단편적 교과 지식만으로는 학습 동기를 높이기 힘듦이 주요함을 알 수 있었다. 본 연구를 토대로 비전공자를 위한 SW교육 운영 방향에 대해 제언할 수 있을 것으로 기대한다.

Estimating the productivity of labor has relied on the experience and intuition of an estimator, or productivity data, such as standard in practical estimation. However, when new technologies and new construction methods employed in the construction industry, Dependence of a quantity surveyor's intuition is increased. This is because of the lack of a systematic methodology which models, estimates, and measures the labor productivity, Due to the historical productivity data is unavailable. Even thought project history data contains information that is important to predict the performance of a project, It can not provide valuable information to model, estimate, and measure the labor productivity. This is because 1) the absence of the productivity measurement system with consistency, 2) the difficulty of reusability of historical data collected. Therefor, this study suggests a methodology which build a productivity model by measuring the productivity of labor and collecting the historical data systematically. In addition, this methology is applied to develop a productivity model of shop-drawing and manufacturing process using descrete event simulation.

While the local plant market is reducing its volume, the plant market over the world since 2000s is rapidly expanding. The nation's construction companies, aggressively dedicated in launching out overseas plant market, increase the volume of orders in that sector, but there also are much difficulty in the project management as those projects ordered are gradually large scaled with more cutting-edge high-tech requirements along with comparatively higher risk. Though the local construction companies have developed their own types of measures to analyze the risk evaluation putting into practice, the specialized decision-making model for the overseas plant market or the risk measure understandable easily and applicable practically is not yet shown. This paper aims at providing the methodology to evaluate the risk by way of constructing the risk evaluation process in order to induce risk measuring elements through appropriate indexing system. Furthermore, through studying the risk management system, it aims to seek for a thorough risk management method from beginning of the project to the end.

The typical Critical Path Method (CPM) leaves it to the construction managers to overcome two problems in developing networks. First, the construction manager needs to prepare information on the type of activities and their precedence relations in order to develop a network schedule. Second, he or she can include space information into the network schedule such as the locations where the activities take place, only with difficulty. These two problems make it difficult for an inexperienced person to create a network. The purpose of this paper is to provide construction managers with set equations of creating a network schedule for multiunit projects. A space-resource combined network creation are presented in this paper, which includes equations for generating a list of required activities, their precedence relations, and information on their location. Information on the space (location) and the resource is the required data for this method. Based on this information, this method divides a project into a number of activities so that each activity contains the information on the location where the activity takes place and the principal resource required for that activity. Precedence relations are then obtained from the sequence of space and resource. This method has the potential to reduce human efforts in scheduling activities.

This paper aims to design a policy-assessment tool liking the Environmental Impact Assessment(EIA) and the Cost Benefit Analysis (CBA). As a step towards the incorporation of environmental and economic considerations, the approach used herein takes the form of integrating quantitative information on environmental benefits and costs associated with implementing the project into the existing framework of the EIA. Our case study is an project appraisal of a solar energy plant. It is confirmed that the technique is operational, however, there are certain limitations for a complete assessment. The difficulty mainly originated from the omission of important information from each step of the valuation process. Alternatively stated, some environmental services are not identified, nor quantified, and nor monetized in the process. More case studies are warranted in the future along with elaboration in methodology of techniques. In addition, the construction of a database on environmental values will be required to accumulate reliable and systematized data. These are the necessary conditions to improving quality in application of techniques as well as providing comprehensive and balanced information to decision makers.

In the metallothermic reduction (MR) process used to obtain tantalum powder in one batch, it is difficult to control the morphology and location of the tantalum deposits. On the other hand, an electronically mediated reaction (EMR) process is capable of overcoming this difficulty. The effect of using $K_2TaF_7$ as the raw material and sodium as the reducting agent on the characteristics of tantalum powder are investigated. As the temperature of the reduction varied from 1023K to 1223K, the powder particles obtained with MR were relatively large $({\sim}34{\mu}m)$, while those prepared via EMR were of uniform $(13{\mu}m)$. In the MR process, the Ta powder recovery rate increased from 37% to 83% at 1123K in constrat with EMR process.

Since Mechanical, Electrical, and Plumbing(MEP) routing is a repetitive and experience-centered process that requires considerable time and human resources, if automated, design errors can be prevented and the previously required time and human resources can be reduced. Although research on automatic routing has been conducted in many industries, the MEP routing in AEC projects has yet to be identified due to the complexity of system configuration, distributed expertise, and various constraints. Therefore, the purpose of this study is to identify the target subjects for MEP routing automation and the constraints of each subject. The MEP design checklist provided by a CM company and existing literature review were conducted, and target subjects and constraints were identified through process observation and in-depth expert interviews for five days by visiting a MEP design company. The target subjects were largely divided into six categories: air conditioning plumbing, air conditioning duct, restroom sanitary plumbing, heating plumbing, and diagram. The findings from interviews show that work reduction and error reduction has the greatest effect on air conditioning plumbing while the level of difficulty is the highest in air conditioning duct and restroom sanitary plumbing. Major constraints for each subject include preventing cold drafts on air conditioning pipes, deviation in ventilation volume in air conditioning ducts, routing order on restroom sanitary plumbing, and separation distance from the wall on heating plumbing. In this way, subjects and constraints identified in this study can be used for MEP automatic routing.
