Planning and Scheduling in Korean has been developed from Bar Chart to CPM, integrated management and EVM were attempted. As growing of overseas projects, Scheduler was also recognized as important one. However, the reality is that most Korean construction projects still remain in the preparation of construction plan and construction schedule in 1990s. The global Planning and Scheduling trend is EOT claims. I would like to understand the global trend of EOT claims and EOT analysis, and to find out Planning and Scheduling measures to successfully promote EOT claims.

석유를 대신할 에너지 원은 원자력 ,태양열,지열 및 풍력등 여러가지를 생각할수 있으나 파력만큼 유망한 자원도 드물다. 바닷물결의 힘을 이용해서 발전력을 얻는 기술이 영국에서는 놀라울만큼 구체화 되어 있다.

산야를 가득 메우는 저 총성은 바로 당신을 위해 울리는 축포다. 우리가 클레이사격장을 찾는 이유는 움직이는 표적(Pidgeon)을 맞추는 재미가 자못 크기 때문이다. 산탄이 타깃에 적중할 때 터지는 쾌감이 그 어떤 사격보다 우수한 클레이사격의 매력을 살펴본다.

Construction delay claim occurs more often than any other claim. Delay claim impacts adversely the company's existence as well as the project's monetary problem. Because the calculation of the delay is not quantitative, owing not to have enough evidence, it is hard to solve evenly the delay claim. So, it is need to cumulate structurely the construction data or evidence during the construction. This study considers the established study about construction delay claim database and the problems and then presents the relation method between phase schedule and database. Finally, this study established the productivity claim database modeling for construction project through conceptual database modeling and logical database modeling based on information needed to make construction productivity database. So. the purpose of the study is to establish the datamodel for productivity management of construction project for calculating the delay days considering the lost productivity.

The insistence of rights and interests in contract is being generalized by opening in construction market which is following F.T.A, internationally. Conditions of contract in construction have different specialities compared with other industries. Different conditions of contract should be established because of a specific character that is different from each construction, such as work, environment, circumference conditions. Although the order of Turn-key is being expanded by increasing construction scale and demanding hybrid function, the suitable regulations of contract are not settled. As a result, various factors of claim is occurring in Change Order-Claim, because they just obey a part of guide-line. This study suggests useful solutions in detail concerned with the main factor of Change Order-Claim by each D/B phases through practical sorting and analysis of the causes of Change Order-Claim.

Topic extraction is a technology that automatically extracts a set of topics from a set of documents, and this has been a major research topic in the area of natural language processing. Representative topic extraction methods include Latent Dirichlet Allocation (LDA) and word clustering-based methods. However, there are problems with these methods, such as repeated topics and mixed topics. The problem of repeated topics is one in which a specific topic is extracted as several topics, while the problem of mixed topic is one in which several topics are mixed in a single extracted topic. To solve these problems, this study proposes a method to extract topics using an LDA that is robust against the problem of repeated topic, going through the steps of separating and merging the topics using the similarity between words to correct the extracted topics. As a result of the experiment, the proposed method showed better performance than the conventional LDA method.

The disputes in construction projects are very important issue for stakeholders. However, many of presented claims have not received the compensation money required, and frequently turned down. The most cause is that the claims are not managed systemically on construction. Therefore, it is important to identify which management works are conducted on construction and how significantly do they relevant to construction claim. This research derives key claim management factors through analyzing causes for claim success and failure, and then presents management works relevant to them. This research also proposes the method for effective claim management and its expected effect through expert interview.

3D surface reconstruction is to make the original geometry of 3D objects from 2D geometric information. Barequet's algorithm is well known and most widely used in surface reconstruction. It tiles matched regions first, then triangulates clefts using dynamic programming. However it takes considerably long processing time while manipulating complex model. Our method tiles a simple region that does not have branches along minimally distant vertex pairs at once. When there are branches, our method divides contour lines into a simple region and clefts. We propose a fast and simple method that calculates medial axes using a minimum distance in cleft region. Experimental results show that our method can produce accurate models than the previous method within short time.

This study was performed to investigate the possibility of water cutting by vegetative propagation method from July to August of Clematis. To find out proper cutting length and rooting growth regulator for water cuttings production, cutting lengths of C. 'Honora' made 1 node and 2 nodes length cutting, which were soaked in NAA $0.1mg{\cdot}L^{-1}$. Rooting rate of cuttings treated by NAA $0.1mg{\cdot}L^{-1}$ was 100% irrespective of root lengths, but that of 1 node and 2 nodes untreated by NAA $0.1mg{\cdot}L^{-1}$ were very low about 30% and 19% respectively. Number of roots and roots length were also highest in NAA $0.1mg{\cdot}L^{-1}$, effects of NAA $0.1mg{\cdot}L^{-1}$ treatment were greater at 1 node cutting. Based on the results, rooting rate for I node cutting of C. 'Pairu' according to NAA (0, 0.1, 0.5, $1.0mg{\cdot}L^{-1}$) concentrations was investigated. Days to rooting were 70-74 days (about 10 weeks), which was not significantly different among the NAA concentrations. Rooting rate increased by NAA concentration. it was about 90% usually and was improved with more than NAA $0.5mg{\cdot}L^{-1}$.
