제품의 생산 및 제조원가는 크게 직접재료비, 직접노무비, 제조간접비로 나눌 수가 있다. 본 연구는 제조업의 제품별 제조원가분석을 위하여 실제 중소기업을 대상으로 관계형 데이타베이스(Relational Database)를 구축해 보았으며, 작업자의 작업시간을 시급으로 관리하여 줌으로써 제품별 원가요소 중 직접노무비(인건비)를 여러가지 요목별로 산출해 낼수 있는 활동중심 경영관리(ABM: Activity-Based Management)를 위한 원가관리 시스템의 프로토타입(prototype)을 설계하였다. 본 시스템에서는 각 작업자별 실작업시간에 따라 발생하는 시급을 작업자의 급여테이블과 연계하여 구함으로써 작업자별 작업시간관리가 가능할 뿐만 아니라, 제품별 제조시간 조회를 통해 표준시간과 비교하는 자료로 제공될 수가 있다. 또한, 제조간접비(제조경비)는 월말 제조원가 산정시 사용자로부터 입력받아 그 달에 생산한 모든 제품에 가중치(weight)에 의해 배분해 주는 방식을 이용하였으며, 직접재료 원가(자재비)는 제품별로 데이타베이스를 구추갛여 제조원가에 반영시켰다. 그리고, 시스템에 유연성을 주기 위해 A/S 제품인 경우는 추가 자재비를 입력시킬수 있도록 고려하였으며, 재공품재고(WIP: Work-In-Progress)등의 정보를 제공함으로써 효과적인 시스템 운영이 되도록 설계하였다.

Process management of reinforced concrete construction that many labor quantity and cost is put at a construction site is very important and gives a lot of influence on the subsequent process. Thus, there will be only used as a useful tool for process control by medical facilities and trend analysis of the flow of the process by the amount of labor input and productivity in reinforced concrete construction. productivity by type and quantity, and comparative analysis. In addition, it is necessary to calculate the standard of estimate and real commitment to labor productivity by type and quantity, and comparative analysis.

Gangform compared with conventional wood and steel form is systemized form which has a capability to install and dismantle form at a time without repeating to assembly and disassembly small members. Gangform compared with ACS has some problems such as 1) Tower Crane load increase, 2) increase in safety incidence during climbing Gangform, 3) decrease in detachment operation productivity, 4) stop work due to climate impacts, and 5) decrease in labor cost, productivity, quality. A conceptual design model of automated Gangform climbing system is suggested for apartment housing construction to show its technical/economic feasibility and workers' safety while increasing operation productivity and concrete quality.

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.

건설현장관리에는 설비관리$\cdot$공정관리$\cdot$품질관리$\cdot$원가관리$\cdot$노무관리 등이 있는데 흔히 생산성향상과 원가 절감을 목표로 하는 공정관리와 원가관리의 목적을 달성하기 위해서는 안전관리는 어느 정도 무시되어야 한다고 생각하는 경향이 있다. 그러나 안전관리도 마찬가지로 원가의 절감을 지향하고 생산성 향상을 목표로 하고 있어 제반관리와 분리될 수 없다.(중략)

Crack sealing is a maintenance procedure that is commonly used to reduce pavement degradation. If cracks in pavements are not sealed, surface water penetration can reduce the strength of the sub-base layers, which can result in increased deflections of the pavement. Reduced strength of the sub-base also accelerates the deterioration of the surface, due to development of greater cracking and potholes. Crack sealing is performed to reduce water and debris penetration, thereby helping to maintain pavement structural capacity and limiting future degradation. The process of sealing cracks in pavements is however dangerous, costly, and labor-intensive operation. Labor turnover and training are increasing problems related to crack sealing crews, and as traffic volumes increase. Automating crack sealing can reduce labor and road user costs, improve work quality, and decrease worker exposure to roadway hazards. The main objective of this research is to develop an automated system for sealing cracks in pavement. Extension of the algorithms and tools presented in this research is also recommended for future study.

Given that the concept of reproducing landscape is similar to that of recording historical sights, places can become special space where memories are archived through meaningful activities. Therefore, place and landscape are the important concepts for understanding the Home of Roh Moo-hyun. This research was initiated when Roh Moo-hyun Foundation's decided to return the Home of Roh Moo-hyun to the public. A research report was published as the first result of this initiative. Then an archive book was recently published based on the first research report. The research report was about philosophical and aesthetic meanings and contents, the layers of accumulated memories, the records based on the accumulated memories, and the attributes of the place, and the possibility of archiving, whereas the purpose of the archive book is to restore and to curate the original meaning of the Home of Roh Moo hyun through cultural events. There are 'three memories' of layers in the Home of Roh Moo-hyun. The first memory is about 'life and dreams' that President Roh Moo-hyun dreamed about after his retirement to the hometown. The second memory is about 'the loss of time' for 10 years of time after the decrease of the President Roh Moo-hyun. The third memory is 'the memory of citizens', which started with the public opening of the Home of Roh Moo-hyun. 'Low Roof House of President Roh Moo-hyun' is the archive book that comprises the three memories which are accumulated in the home of Roh Moo-hyun and 'record language' full of meanings.

It is generally acknowledged that subcontractors mostly allocate their resources to project relying on their previous experiences, instead of data-based judgement. Installing residential fire protection systems, typically performed by subcontractors, is labor-intensive job and its schedule is frequently changed as the contractor master schedule is often revised. Nevertheless, it is still important for subcontractors to make much effort to improve labor productivity through a thorough planning for scheduling and resource allocation. The purpose of this study is to identify significant factors that affect labor productivity for residential fire protection system installation. For this purpose, 50 potential factors that may affect productivity were identified based on literature reviews and expert interviews. These factors were further explored using correlation analysis and ANOVA test. The results showed that the labor productivity is significant impacted by various project characteristics.
