본 연구는 공공건설공사 중 조경공사 적산의 단가 비교로 적정 공사비 산출방안을 모색하고자 하였다. 2011년 상반기 실적단가에서 조경공사로 분류되는 12항목 중 유사기준인 7항목을 대비하며, 준용 공종은 5개 현장에 적용된 실적단가 80항목 중 비교 가능한 35항목을 유사기준인 2011년 3월의 표준품셈 단가로 대비하였다. 조경부문 7항목의 실적공사비율은 항목별로는 104.86%, 총공사비로는 92.09%이다. 실적공사비율이 높은 이유는 암반 적용 여부로 씨앗뿜어붙이기의 높은 비율도 있지만, 근본적인 이유는 잔디와 씨앗뿜어붙이기의 사면처리 비용 때문이므로, 품셈의 불합리성과 토양 종류별 기준별 보정계수 규정을 세분할 필요가 있다. 토목과 건축 준용부문 35항목의 실적공사비율은 항목별로 78.65%, 총공사비로는 71.31%(70.17%)이다. 이는 실적단가가 구조적으로 실제 금액을 반영하지 못하는 점과, 품셈은 인력시공에서 현실성이 결여된 때문으로 판단된다. 국토해양부 발표인 85.1~91.2%의 실적공사비율은 신규 전환품목 단가이므로, 이 결과는 실제적인 실적공사비율로 추정되며, 실적단가가 적정 비율을 보이도록 검증 후 보완하고 표준품셈도 이러한 실적자료 등으로 보완이 필요하다.

기존의 품셈과 지방세법은 건설중장비가 수 년에 걸친 감가상각 대상임에도 불구하고, 물가지수를 제대로 반영하지 못하고 있다. 이에 본 연구에서는, 법인세법과 지방세법 및 기업회계기준서를 분석하여 국내 감가상각제도의 특징과 상각방법을 정리하여 제시하였고, 경제성 이론이 반영된 건설중장비 자본회수계수를 제시하였고, 정액법과 정률법을 사용하여 표준품셈을 기준으로 한 감가상각과 세법을 기준으로 한 감가상각 사례를 제시하였다. 개선방안으로는, 건설중장비의 자발적 사용기간 신청제도와 현행제도와의 관계를 설명하고 도입을 제안하였으며, 국내물가지수를 기초로 월단위 기계경비 감가상각율표를 개발하여 제공하였으며, 그 적용방안을 예시하였다. 또한, 제안한 방안의 장점과 단점을 분석하여 연구의 적용한계와 차후 개선방향도 제시해 보았다. 본 연구를 통해 품셈과 세법에 보다 합리적이고 객관적인 현실성을 반영할 수 있을 것으로 판단된다.

Construction cost index is generally used to estimate the new project cost based on past construction data and to adjust contract cost when the price change of various articles and items of expenditure composing the contract occurs. In Korea, it is mostly used for adjustment of construction contract cost due to fluctuation of prices. However index adjustment rate which is used for adjustment of construction contract cost had some problems in calculating cost index of each expenditure item that could not reflect properly the change of construction cost. For supplementing these problems, the research of developing construction cost index has been executed. Through the precedent research, these problems were partially resolved but still remain. Therefore this research proposes method of making cost index that utilizes representative items of labor, material, and equipment by analyzing bill of quantity of road construction, through analysis and comparison of precedent study. By using this method, it is expected to solve problems which were not reflected in precedent studies.

The purpose of this study is to understand the meaning of‘housework’. In order to understand the intrinsic meaning of housework, we have to distinguish between ‘individual meaning’and‘institutional meaning’. The former is related to the concern, intent, habit, need, desire, and motivation of the given individual, while the latter is related to the social value, norm, and convention of human behavior. The majority of the studies on housework have been made by focusing on individual meaning. As the individual meaning of housework has gradually been emphasized, it has been forgotten that‘housework’itself is a very important part of‘home life’, and then the importance of home life has gradually diminished. Housework is naturally carried out in the process of human history, and housework reflect total human wisdom. In other words, it is thought that it is possible to grasp the total meaning of life in housework. Our life can be richer than now by increasing the quantity of philosophical analysis of the phenomena related to housework.

This study used to the satellite photograph and drew up a flood inundation map. To past used digital map and showed reflect the inundation map and change of the city was difficult. The acquisition of the satellite photograph is easy from internet Site of Korea and is updated quickly. So, used the satellite photograph from flood inundation drawing up of existing and reflected the change of the city. Drawing up method of the inundation map in compliance with the research which sees the reflection of the land use which is actual is possible. Results of HEC-RAS with depth and an inundation location to be show easily. But there is to a combination method of the satellite photographs and GIS data and more objective and the subject the development of the technique which has reached fixed quantity must be researched continuously judges.

The purpose of this study is to provide basic guidelines for qualitatively advanced children's facilities and spaces in grand bookstores. The main concept is considered with a situation that grand bookstores of large corporations are increasing in quantity, but their social missions for the user are often being connived. The study is performed by research of current six domestic grand bookstores, two branches of each three large corporations, larger than 2,500py in Seoul, and the research is applied to Murtha's User Benefit Criteria as a basic format. As a result of the research, some problems to be improved are detected in ways of behavioral facilitation, physiological maintenance, perceptual maintenance, and social facilitation, therefore findings in survey turned out to be parents' dissatisfaction in many aspects. Finally, with this result, it is desirable for interior designers to reflect the indicated insufficient elements to their following children's bookstore space design for the user, children and their parents.

The standard estimation system, used to estimate the predetermined cost of construction work, is measured by the standard and typical construction methods and field conditions. And the standard estimation system is applied to basic data for the measuring of construction cost, such as the consumed quantity of material, labor hours, and machinery cost. However it does not reflect sufficiently for the diversity and reality of constructions work Therefore, this study is recognized the necessity of new cost estimation models for the rational construction cost estimation. To improve estimation technique and construction ability, it was analyzed labor hours, production volume based on the work crew in construction work.

To secure quality of dam construction needs appropriate construction duration. Tight construction schedule may have negative influence on infrastructure quality, work safety and maintenance cost. It is necessary to reflect proper construction duration in the planning phase. There have been standards for estimating construction duration of building and industrial complex development but dam construction have not. In order to estimate construction duration of CFRD, feasible study reports and design reports were analyzed to acquire available information. After that, considering on construction duration methods such as comparison with similar cases, approximate estimating formula, approximate quantity assumption were adapted to Critical Path items. Hence, this study present framework for construction duration estimating of CFRD in the planning phase. This framework can be applied other types of dam along the same line.

Drill and blast method has been most widely used in tunnel excavation, after NATM (New Austrian Tunneling Method) was introduced in 1983. The NATM method utilized mass of shotcrete to secure the bearing capacity of tunnels. Overbreak defined how much larger the actual excavation was than the planned. When it became larger, more shotcrete was required to fill in it Here, payline fixed allowable overbreak, referring to payable amounts of shotcrete. Since owner was not responsible for shotcrete exceeding payline, it was important to properly establish the standards for payline. Although the standards were provided in 'Poom-sam'(standardized quantity per unit), they did not properly reflect the actual conditions for excavation. Thus, this study reviewed existing domestic and foreign standards for overbreak, and estimated overbreak for each type of support using survey data, and finally provided the improvements on the current standards.
