In rapidly changing circumstances, the construction industry shows tendency to be more complicated and expanded and these changes are becoming the main factors aggravating uncertainty in straightening construction costs in the industry. The most important process in preliminary phase is calculation of appropriate construction sum and accurate estimation is required to accomplish it. Currently, local constructors draw up estimates by using the ‘per square meter’ calculation method or by applying of previous cases as they are. These methods become suppressive cause for making clear decisions by occurring errors in quantity survey in a way of data emission, replication and so on. Therefore, in this study, approximate estimation model of finishing construction shall be proposed to assist people to make prompt decisions in initial design stage. To develop this research, the existing quoting practices shall be presented and categorized by usage of space. To achieve this, information on performance, furnishings and unit price according to space definition has been collected in advance, which again enable ontology knowledge classification scheming database of space unit to be utilized and presented as knowledge information.

Recent projects for transferring Public Office buildings and estimation of appropriate construction expense are highly important for both government and construction firms. Moreover, estimation and management of construction expense can be regarded as extremely important duties for effective execution of a national budget as nation’s finance is invested in the Public office building projects progressed by the government. To progress one project for Public office building, not only the organization demanding the project but also an investment screening organization, a budget-managing organization, a feasibility assessment institution and many other related organizations participate in the project and a lot of decisions arisen from the project operation are made on the basis of construction expenses calculated for relevant stages. And estimation of rational construction expense is also critical for designers in order to create design within the fixed budget simultaneously with securing the quality and efficiency of structures to the maximum. Therefore this research suggested an improvement process to analyze problems in current construction expense management process and to administer the construction expenses effectively.

본 연구의 목적은 지진모의실험을 위한 1:5 축소 10층 R.C. 공동주택 모델의 제작과정을 통하여, 실험체의 효율적인 설계 및 제작 과정을 개발하는 것이다. 실험체의 축소율은 가용한 진동대의 크기(5m{\times}5m)와 최대 허용무게(600kN)및 모델 철근(D3 볼트, {\phi}2 강선)의 경제성과 상용성을 고려하여 결정하였다. 모델 철근은 현장에 바로 설치하기 어렵기 때문에 철망을 제작한 후 현장에서 조립하였다. 벽체와 슬래브를 동시에 타설할 경우 거푸집의 탈형이 매우 어렵기 때문에, 벽체를 먼저 타설하고 양생 후 탈형한 뒤 슬래브 거푸집을 설치하였다. 벽체 거푸집은 반복 사용이 가능한 Slip form 형태로 한쪽은 합판, 다른 한쪽은 아크릴로 제작하여 타설시 밀실도를 확인할 수 있도록 하였다. 1:5 축소 10층 R.C. 공동주택모델을 제작하기 위해 총 제작 기간은 약 6개월이 소요되었으며, 전임 연구원 5명, 작업보조원 612명 일의 인원이 투입되었다.

With the trends of massiveness and complexity of construction, the main agents of construction have considered the various types of risk management strategies to minimize the loss caused by the risk factors from the nature of construction project, regional characteristics, and scale of construction. The risk management has been conducted, because the risk factors have exacerbated the condition of construction in terms of the level of productivity, quality of construction, atmosphere, and budget. Based on thε interests regarding risk factor management, the current study suggests the work breakdown structure-based process. Additionally, based on the work breakdown structure, the risk factors on constructions are identified and stratified depending on the level of salience of each risk factor. The purpose of result is to lead Korean Land Corporation understand and control the risk factors properly for the advanced construction process of Korean Land Corporation. Ultimately the current study contribute to advance of efficient risk management strategies by using ANP method, which identify and control the primary risk factos depending on the impact of the interaction and subordinate relationship between risk factors.

A prediction of construction cost in preparation for construction document is calculated in compliance with the unit cost in Public construction of korea. This eventually means that the reasonable construction cost of a building can't be determined before construction document phase cost of construction is settled and that the cost of construction is calculated inefficiently because of connection failing between cost management of detailed estimation and information. To improve those problems, therefore, Cost estimating model of structural building elements with approximate quantity survey method is suggested in this research. The model predict the amount of materials and the cost of construction on the basis of historical similar cases. In the direction of data analysis of this research, ratio statistics value is put to practical use to fit into the peculiarities of approximate estimate of each work trade on the basis of actual data amount of materials of historical cases. In addition, the construction phase is connected through the result of a approximate estimate sorted by elements, details work trade.

We amplified D1 and D3 expansion segments of the 28S ribosomal RNA from 10 Suanguina moxae populations found in Korea. The amplification of the D1-D3 expansion segments of 28S gene of all populations tested produced a single PCR product approximately 1.03kb in size, suggesting the lack of D1-D3 expansion region size polymorphism among populations. The secondary structure model of 28S expansion segments D2 and D3 for Subanguina Moxae was predicted based on free energy minimization with comparative sequence analysis and new sequence alignment was conducted based on predicted secondary structure model. The predicted model was compared with previous predicted models of plant and animal parasite nematode. This predicted secondary structure model will provide valuable information to allocate positional sequence homology and reconstruction of reliable phylogenetic trees.
