매년 사업주와 근로자로부터 상담한 내용을 돌아보면 우리 사회 노동시장의 현안이 무엇인지, 인권수준은 어떠한지, 노동행정의 방향이 어떠한지를 확연히 체감하게 된다. 그 중 하나가 육아휴직제도이다. 20년 전만 하더라도 육아휴직은 거의 허용되지 않았다. 결혼 또는 임신하면 퇴직이 관행이던 시절이었다. 관행에도 불구하고 임신한 근로자가 퇴직하지 않으면 출 퇴근이 어려운 지방으로 배치전환하거나, 직무를 변경하고, 담배연기 가득한 방 가운데 여성근로자를 근무시키는 비인간적인 처사도 행해졌다. 2~3년 전만 하더라도 "우리 회사는 육아휴직은 안된대요. 그럴바엔 그만두래요. 아이 맡길 곳도 만만치 않은데 어쩌면 좋아요"라는 여성근로자들의 상담이 한달에도 몇 건씩 쏟아져 나왔었다. 초기 여성노무사가 소수이다 보니 워킹맘들의 노동법률상담을 할 기회가 많았다. 때론 사업주들을 설득하고, 중재하고, 처벌조항을 들어 압박하기도 하면서 육아휴직을 권장했지만 기존의 관행과 문화가 일시에 변화하기는 어려운 일이다. 여성의 경제활동율이 늘어나고 출산율이 줄어들면서 정책적으로 출산 및 육아휴직을 장려하는 정부의 감독행정 강화, 그간 노동계 및 시민사회단체의 노력 등으로 인해 법률에 규정된 육아휴직제도가 비로소 현실적으로 보장되어가고 있음을 목도한다. 이즈음에 육아휴직자의 연차휴가 사용, 퇴직금, 육아휴직급여 등에 대한 문의가 많은데 그만큼 육아휴직자가 늘어났다는 것을 반증하는 결과이다. 따라서 이번호에서는 출산휴가 및 육아휴직자들의 연차휴가 사용과 퇴직금 산정방법, 출산 육아휴직급여에 대해 알아보고자 한다.

During the last few years, the use of Pre-tensioned spun High strength Concrete(PHC) pile has been gradually increased in many construction sites such as super high-rise and large building construction. there is almost no specific code and/or standard described in the specifications to check verticality for Pre-tensioned Spun High Strength Concrete pile installation process. The most commonly used method for the vortical PHC pile installation is a naked-eye measurement or water level measurement conducted by assistant crew in the construction sites. And recent analysis results of the pile cutting work revealed that it frequently makes a lot of cracks which significantly reduce the strength of the pile and is very labor intensive work, thus requiring a large amount of additional time, costs, and efforts. The main objective of the research is to analize problems and to improvement. measure of PHC Pile Construction. The improvement measure present to the main problem with survey and discussion.

The purpose of this study is to evaluate the characteristics of the structural behavior in precast segmental prestressed concrete girders, which consist of five precast segments. These girders were developed to save labor and cost in construction field reducing a term of work. Therefore, four different types of specimens of 25m in length were built, and they were tested and analyzed for observing flexural behavior. The analysis included the investigation of the flexural behaviors in varying tendon amount and at joints using the relationship between moment and deflection. Moreover, nonlinear finite element analysis was utilized to verify the experimental result.

Escalation method examining the changes in price index has been widely utilized in public construction projects. The previous escalation method determined estimated changes in price based on the average unit price of contract items over a period of time. In relation to this method, the issue has been raised that the fluctuation rates of previous method show different trends compared with other related price indices, as the influence of the small group of contract items with large unit prices overwhelms the others. This research suggested an improved escalation method which estimates the fluctuation rate by examining the changes in CCI (construction cost index) and applies it to the total amount or the partial amount deducted for labor cost in price escalation for previous bid price method. To verify the improvement, a case study is conducted on an educational facility, and the fluctuation rate was estimated in two different base periods (short term, long term). The results over the long term showed similar tendencies to those of related price indices, as well as significant differences in fluctuation rates compared to those of the previous method.

Unlike other craft workers, construction craft workers perform their work under diverse working conditions, which means that their working pattern and postures continuously change. While construction craft workers are vulnerable to musculoskeletal disorders, due to the unique factors of their working conditions, their actual condition has not yet been accurately investigated. For this reason, this research aims to develop a method of measuring the musculoskeletal load of construction workers by reviewing various motion measuring methods to which state-of-the-art sensors are applied. This research is expected to serve as the basis for developing a system to measure the musculoskeletal load of construction workers.

The labor cost on construction project of Korea is calculated based on the Wage Rate in Construction of Korea which is published by Construction Association of Korea. The Wage Rate in Construction of Korea does not have any variation on the wage following skill level of labor although it has 123 work categories. In addition, the classification on skill level and career of construction labor in Korea does not defined. Therefore, to establish the concept of the classification on skill level and career of construction labor, this study aim to compare the difference between Wage Rate in Construction of Korea with Award system which present grade on skilled labor.

Today, the potential safety risk is increased due to a construction industry is high-rised, mechanized, and complexed. Most workers injured in accident caused by lack of safety awareness. Therefore the safety education is focused in construction site, but it can not get workers' interest and has many problems to reduce construction accident. This study investigated the effects of education used BIM intended for workers in construction site to verify the objective effectiveness in future.

Recently, the construction policy is rapidly changing and construction project becomes larger and more complex. Specialty contractors are in charge of the actual construction work, but they are considered to have low competence level. To strengthen competence of specialty contractors' employees, above all, it is essential to evaluate and to analyze the competence factors level for specialty contractors' employees. However, there is no in-depth research on competence factors level for specialty contractors. Therefore, the purpose of this study is to analyze the competence factor in order to find the high priority factor. The result of this study can be utilized for development of effective educational program for enhance specialty contractors' competence.

An installation of the construction lift has a few limitations by many constrains and these have influences on labor productivity, that can be changed by vertical-transportation management. In the super-tall building construction, a management of construction lift operation is one of the most important factor, but existing methodologies depend on skilled practitioners' experiences. And it is true that the expertise resulted by the experiences does not transfer to the next generation. This study is a part of lifting-management simulation development which aims at the optimal construction lift management. A proposed algorithm is focus on lifting time calculation considering an acceleration capability. This research evaluates the result accuracy using comparative analysis on simulation result and field measuring time.

As aged infrastructures have been increased, the importance of accurate maintenance costs and proper budget allocation for infrastructure become prominent under limited resources. This study proposed a mapping algorithm between representative defects, repair methods, and the estimated maintenance costs for concrete bridges. In this regard, using BMS (Bridge Management System) data analysis, bridge repair methods were classified and matched with defects according to their locations, types, and sizes. In addition, the maintenance costs were estimated based on the amount of work-load and quantity per unit using CSPR (Cost Standard Production Rate). As a result, the level of accuracy was an average of 85.1 % compared with the actual bill of quantity for Seoul bridge maintenance. The accuracy of maintenance costs is expected to be enhanced by considering the various site conditions such as pier height, extra charge conditions, additional equipment, etc.
