The construction arbitration field has developed considerably since the latter half of the 1990s. Through analysis of construction arbitration cases taken up by KCAB, this paper intends to show the present condition and the improvement direction of construction arbitration in Korea. The number of construction arbitration cases filed at KCAB has been increasing rapidly after 1997, but recently the rate of increase has tended to decline. From 2000 to 2003 the number of arbitration cases increased 23％ each year, on average, but in 2003 the increase was only 7.6％. In the very beginning, public construction claims made up the majority of all construction cases, however, civil construction claims are increasing gradually. The arbitration amount in the construction field is very high, owing to public construction claims. For example, the arbitration amount per case was 5 billion won, on average,. in the public construction field. It is shown that the claimants of arbitration are mostly constructors and the main reasons for making claims are to demand payment for construction and payment for additional work. KCAB investigated the performance status of arbitration awards. The voluntary performance rate for awards in construction arbitration is nearly 80％ and in 11％, a suit was filed to appeal the arbitration award. In spite of the development of construction arbitration, some improvements are requested. There have been arguments about the effectiveness of selective arbitration agreement in the General Terms of Construction Contract. This has caused a decrease in arbitration cases, so improvements in this dispute settlement clause need to be made. Enforcement of arbitration awards is granted by the judgment of a court. Resulting from this, appeals for arbitration awards are not allowed, however, up to three appeals for the enforcement of awards are allowed in court. As such, the enforcement system for arbitration awards needs to be improved and simplified.

본 연구는 연약지반상에 축조되는 농업용 저수지의 합리적인 안정관리의 기준을 수립하기 위하여 현장계측결과를 기초로 시공중 또는 완공후에 측방유동 등으로 인하여 국부적인 전단파괴 가능성을 현장계측치로부터 비교분석하여 다음과 같은 결론을 얻었다. 1. 한계평형법에 의해 안전율을 비교하면 Spencer방법과 간이 Bishop방법은 거의 유사하게 나타났고, 간이 Janbu 방법은 약간 작게 나타났다. Spencer방법은 흙의 활동부분에 대해 힘과 모멘트 두 평형방정식을 만족시키는 해석방법이므로 저수지의 안정성을 해석하는데는 합리적이라 판단된다. 2. 수평변위는 물리적 성질의 변곡점이 형성되는 부분에서 급증하였고, 성토의 안정관리는 각 토층의 경계부분에서 가장 불안정한 상태로 나타나므로 분석시 가장 우선적으로 검토하여야 한다. 3. 수평변위속도에 의한 안정성 평가방법은 파괴 가능성을 미리 예측하는데 상당히 효율적인 방법이라고 판단되고, 전단파괴 가능성이 높은 무처리 지반에서의 안전율의 기준은 처리지반보다도 신중하게 선정하여야 할 것으로 판단된다. 4. 점증하중에 의한 시공중 안정성을 계측자료를 이용하여 분석한 결과, 파괴기준선에 접근하여 위험가능성이 있는 부분도 있었으나 성토체는 안정한 것으로 확인되어 안정관리상 파괴기준선으로 안정성을 평가하는 것보다는 곡선의 기울기로 판단하는 것이 합리적이다.

본 연구에서는 GIS 및 RS를 이용하여 평안북도 서부지역을 대상으로 1988년∼2001년 사이의 토지피복과 식생 분포의 시ㆍ공간적 변화를 살펴보았다. 이를 위해, Landsat TM 및 ETM 영상을 사용하여, 기하 방사 보정 후, 감독 분류와 NDVI 분석을 실시하였다. 분석 결과, 평안북도 삭주, 대관, 구성, 의주 지역에서는 13년 동안 산림이 감소하고 시가지, 인간의 간섭에 의해 발생한 황무지, 범람과 사태 등의 자연적 요인에 의한 나대지 등이 증가한 것을 관찰하였다. 또한, DEM 분석을 통해 대부분 지역에서 고도가 높고 경사도가 큰 지역까지 시가지 개발 및 확장, 개간이 이루어지면서 더 많은 황무지가 발생하고, 비교적 높은 고도에서도 NDVI 값이 감소한 사실을 알 수 있었다. 이러한 변화는 지형적 특성을 고려하지 않은 채 이루어진 개발에 의한 것이며, 산사태 등의 자연재해 방지, 안정적인 식량공급 등을 위해 많은 연구 및 해결책 제시가 필요할 것으로 본다.

The purpose of this study is to conduct base line research, which is based on requestion of international married immigrant women, for developing social adaptation and family enrichment program for those population who reside in Korea. The survey questionnaire was distributed to 142 international married immigrant women who reside in Seoul to research program participate satisfaction and requestion. Analyze the study results, frequency, percentage, t-test, ANOVA and Duncan-post test were utilized. As a result, overall satisfaction toward program that offered by organization was highly ranked. Visiting service showed high score of satisfaction but mentor service that strongly possess sacrifice showed lower score of satisfaction. Vocational and job-related skill improvement education presented less satisfied degree of satisfaction but cooking class, computer class, training education for native-speaking instructor present high level of satisfaction. Second, the requisition of target population, who did not participate program, presented lower than the satisfaction, still present high demand of variety area of program. Among them, assist child nurturing and vocational and job- related skill improvement education showed high demand. It enable to predict that they are eager to get support toward parent role and self-realization. Third, when the difference were analyzed to compare the subjective judgement toward life adaptation in Korea and the satisfaction for program user and the requisition of non-user, the meaningful differences were founded; especially, individuals who possess confident degree of computer skills and Korean(reading, speaking, and listening) showed higher degree of satisfaction to vocation and job-skill related improvement education. This study has a practical implication, which is based on the study results, on developing a program to support international married immigrant women and multicultural families to satisfactory settlement in Korea life and to maintain healthy families.

This paper shows theresults of centrifuge model experiments to investigate the behavior of a replacement method in dredged and reclaimed ground. For this experimental work, centrifuge model tests were carried out to investigate the behavior of a replacement method in soft clay ground. Basic soil property tests were performed to find the mechanical properties of clay soil sampled from the southern coast of Korea, which was used for the ground material in the centrifuge model tests. The reconstituted clay ground of the model was prepared by applying reconsolidntion pressure in a 1 g condition with a specially built model container. Centrifuge model tests were carried out under the artificially accelerated gravitational level of 50 g. Replacement material of lead with a certain degree of angularity was used and placed until the settlement of the replacement material embankment reached a state of equilibrium. Vertical displacement of the replacement material was monitored during tests. The depth and shape of the replacement, especially the slope of the penetrated material and the water content of the clay ground were measured after finishing tests. Model tests for investigating the stability of an embankment after backfilling were also performed to simulate the behavior of a dike treated with replacement and backfilled with sandy material. As a result of the centrifuge model test, the behavior of the replacement, the mechanism of the replacement material being penetrated into clay ground, and the depth of the replacement were evaluated.

Arbitration is an essential methods of settlement for disputes in international commercial transaction. UNCITRAL Arbitration Rules have been in force after adoption in 1976. Over the 30 years, UNCITRAL Arbitration rules have been modeled for domestic and international arbitration institutes for setting and revision on their arbitration rules. UNCITRAL Committee has published the revised Arbitration Rules which entered into force after 15 August 2010. Therefore new version of arbitration rules are substituted for the previous version of UNCITRAL Arbitration Rules 1976 since its enforcement. The revised arbitration rules of UNCITRAL have been changed in various items for convergence with new trends and modern practices on arbitration including information communication and technology. The revision of arbitration rules focused on resolving problems in practice and codifying best practice to enhance the efficiency of arbitration conducted under the rules. There are considerable in a number of important respects on the removing the restricted in writing requirement for information technology, adapting the multiparties arbitration, joinder arbitration, truncated arbitral tribunal and adjustment in terms and condition and construction simply. Also a number of provisions have been refined, varied and clarified with new articles included. Conclusively the new revised arbitration rules fill a number of gaps which became apparent in the UNCITRAL Arbitration Rules 1976 to bring into line with new modern practices of international arbitration rules in international commercial disputes. This paper focus on the study the problems and inspired points on significant revised provisions and its considerable points in arbitration environment. This paper is approaching to the comparisons of UNCITRAL revised Arbitration Rules 2010 with previous Arbitration Rules 1976 of UNCITRAL and International Arbitration Rules 2011 of KCAB.

This study starts from the genealogical analysis of the urban public spaces through local history of Seoul which is significantly different from western countries. The analysis targets the discourse on the urban street, the basic unit of urban tissue and the settlement condition in urban life, which defines urban space-structure among the urban public spaces. And this research classifies and categorizes the value recognition and policy value occurred each period. Based on these, this research defines the progress levels of urban public design policy in Seoul as follows. Results Firstly, 1890's and 1900's was the period of development in commerce and industry, which caused congested and crowded streets. The open port policy allowed the experience of the foreign circumstance, and thus the identity of the urban streets and the value of symbolism come to realize among the society. During the Japanese colonization, urban streets put on modernized images through the urban remodeling out of the context according to the colonization policy. The brand-new values such as publicness and amenity are injected as well as modern regulations by system and authority. From Liberation to 1950's, it performed only street restoration as a repair from war with Japanese colonial system because of the political confusion and administrative vacuum. Finally, each period can be defined as follows. 1890's and 1900's can be defined as 'spontaneous finding the modernization' because urban street was intentionally transformed by the empire. Period of the Japanese colonization can be defined as 'the formation of modernized urban street concept and the compulsion of modernized regulation.' And period of from Liberation to 1950's, can be called as 'the absence of value recognition and maintenance of colonial system.' methodology.

The purpose of this paper is to classify two study sites into the biotope types and investigate the landscape ecological characteristics of them. This will be available for the rural planning in the aspect of environmental preservation. The summaries of the result are as follows. 1) In the result of the area assessment in biotope groups, a dry field (32%) and a paddy field (28%) are more than 50%, but settlement space and water space are less than 10%. The result shows the land use condition of rural areas. 2) In the investigation result of elongation, running water spaces are higher than other biotope groups relatively, it is because they long shaped and 1-3m narrow. 3) In case of Fractal index analysis, residential spaces and cultivated lands are investigated to be lower in numerical value, it is because they have the definite borders and get simple in the border of landscape by human intervention. 4) In case of dispersion degree, the dry field has the highest value because they are located close by forests spread widely around study sites. It means that the land which is used by artificial purpose get more value rather than natural lands 5) In the connectivity analysis, a paddy field and a residential space appear the highest. It is because residence spaces spread intensively through roads and a paddy field, through streams. 6) In rural landscape, the diversity of landscape is investigated to be simple. A paddy field and a dry field contain small sized patches that have been divided by human intervention. Besides, there appear much different vegetation around waterways and farm-roads.
