현행 건설일용근로자의 포괄임금 계약에 대한 대법원의 판결과 고용노동부의 지침이 변경되어 혼란이 야기되고 있다. 고용노동부는 지난 8월 8일 건설 일용근로자의 포괄임금제 업무처리 지침을 변경하고 일선 사업장에 시정 지시 공문을 발송하고 있다. 새로 변경된 건설 일용근로자의 포괄임금제 업무처리 지침은 일당제 일용근로자의 고용형태를 두 가지로 구분하여 일급에 포함되었다고 볼 수 있는 수당과 그렇지 않은 수당을 명시하고 있다. 일급에 포함되었다고 볼 수 없는 수당의 경우 해당 근로수당을 포함하여 체결된 근로계약이 부적정하다는 입장이며, 이에 따라 일당제 일용근로자를 사용하고 있는 사업장에 시정지시를 하고 있다는 것이다. 그러나 현행 판례 및 행정해석, 기존 고용노동부의 지침은 제수당을 미리 합산한 일정금액을 지급하기로 하는 포괄임금 계약을 인정하고 있다. 이처럼 판례와 고용노동부의 지침이 서로 다르고, 새로 변경된 고용노동부의 지침을 반영하는 새로운 판례가 아직까지 나오지 않았기 때문에 사업장에서는 사례별로 유연한 대응이 필요하다.

Flying net should be installed on every 3 or 4 construction floor from 8m above ground according to the rule. In the apartment housing construction, flying net installation work has been recognized the most dangerous work among the whole works because a small mistake of labors might make their death accident. Sub-contractors specialized in flying net have been developing various flying net types. However, most works of installing flying net as working with the developed system are performed outside the apartment housing, so that the risk of fall in works of installing supports and unfolding net is still high. Furthermore, as using the previously developed flying net labors might bump into the frame or the wire rope for supporting so that it makes secondary accidents. The objective of this research is to produce the proto-type of anti-collision flying net system based on the result of problem analysis on the installation and detachment process and suggest the improved anti-collision flying net system, which is able to improve safety and field applicability by conducting field experiment and analyzing performance.

In domestic public construction, disputes are increasing due to differences among stakeholders regarding contract price adjustment. In particular, the actual cost-plus fee for overhead costs due to the schedule extension cannot be agreed upon at the administrative phase, and most of them seek judicial judgment. Thus, this study aims to propose a 'sufficiently satisfactory' alternative to reach an agreement before disputes in order to minimize disputes related to the calculation of additional overhead costs. To this end, this study proposes three alternatives based on the rate method. Firstly, when calculating additional overhead costs, it is not calculated as an actual cost-plus-fee method, but as a rate compared to direct labor costs among net direct costs. Secondly, the calculated indirect labor costs are compensated for up to the legal maximum of legal limit costs such as general management costs, profits and so on. Thirdly, it reflects overhead costs increased or decreased due to change orders. Risks were analyzed by collecting expert opinions on the proposed methods and applying actual cases. Finally, as a result of investigating the level of consensus for each stakeholder, it was confirmed that all stakeholders could agree regardless of the size of the company. The result of this study is expected to as a useful tool among stakeholders in the construction fields that can be able to easily agreed upon.

About 93$\%$ of domestic teal estate construction firms registered as the end of 2001 recorded net profits of only less than 500 million won(including firms in the red) for the term. As a result of having analyzed the ratios of sales costs and the structural ratios of sales costs for the past 10 years, it was found that there have been great changes in structural ratios of sales costs. Material costs and labor costs have gradually decreased, but outsourcing costs of processing have greatly increased. In order to find activity points which are fundamental to cost control, the methods of new activity based cost management have been pursued. The characteristics of real estate construction industry lie in the fact that contract prices (sales in) are fixed and amounts of profits differ depending on the use of costs. In order to create maximum profits from fixed contract prices, the new activity based cost management has been proposed. The control of operation budgets and management costs is designed to control their schedules and expenses in different respects. Operation budgets ate executed with specific activities and management costs are controlled as a form of material costs, labor costs, out sourcing costs and expenses which are details of expenditure. In order to execute them by using the methods of new activity based cost management, first of all, we have to analyze what activity drivers ale and how much added values such activities can create. It is considered as a method of cost management which is necessary far the survival management of real estate construction industry.

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.

As buildings become larger, higher and more complex in most construction sites, construction projects have to deal with transportation of more materials, labor and equipment, necessitating more use of construction equipment. Notably, in the high-rise building and plant construction projects mobile cranes are adopted more frequently among different types of construction machinery, which also results in serious industrial accidents relating to the use of crane. To reduce serious industrial accidents involving cranes, researches on its stability is in need. The research herein aims to study how to select sling and lug of mobile crane and review its stability. The research outcomes herein will make considerable contributions to selecting mobile cranes efficiently and ensuring their stability.

The construction cost index and the forecasting model of apartment house can be efficient for evaluating the validness of the fluctuating price, and for making guidelines for construction firms when calculating their profit. In this study the previous construction cost index of apartment house was improved, and the forecasting model based on X-12 ARIMA was developed. According to the result, during the last five years the construction cost, excluding labor expense, has risen approximately to 22.7%. And during next three years, additional 16.8% rise of construction cost is expected. Those quantitative results can be utilized for evaluating the apartment house's selling price in an indirection, and be helpful to understand the variation pattern of the price.

5월은 유난히 기념일이 많은 달이었습니다. 올해는 대통령 탄핵으로 치러진 조기대선으로 인해 공기업, 공공기관, 대기업 등 투표일이 휴일로 지정된 사업장에서는 월요일 연차휴가를 내고 연휴를 즐기는 근로자들도 많았습니다. 그러나 주의 사업장 등을 보면 총선이나 대통령 선거 등 선거일에도 정상적으로 영업하고, 대기업에 제품을 납품하는 협력업체의 경우 선거일에도 정상적으로 근로하는 경우도 많았습니다. 선거일 근무는 위법할까요? 백화점, 병원, 식당 등 대통령선거 및 국회의원 선거일에도 정상적으로 영업을 하는 사업장에 근무하는 근로자들은 선거일에 근무하면 휴일근로수당이 발생할까요? 투표일이 휴일이 아니라면 피선거권을 보장해 주어야 하는 기업들은 어떻게 해야 할까요? 선거 때가 되면 항상 포털 사이트 상담란에 빈번하게 올라오는 질의인데요. 이번호에서는 선거일이 휴일인지 여부에 대해 살펴보고자 합니다.

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)
