It has been said from previous studies that the preconsolidation pressure (p$\sub$c/)of Nangton Rive. deposit is considerably less than the in situ effective burden pressure (p'$\sub$$\upsilon$ο/). Question has risen whether this small pc vale is due to under consolidation or unsuitable laboratory test including low small quality. As a cooperative research program between PHRI (Port and Harbor Research Institute) and Pusan National University, an extensive soil investigation was carried out at a site of Yangsan, Pusan, using the Japanese sampler. It Is found that although p$\sub$c/ value at the site is slightly greater than p'$\sub$$\upsilon$ο/, its over consolidation ratio (OCR) is quite small compared with aged normally consolidated clay in Japan.

We performed a free vibration analysis of skew composite laminates with or without cutout based on the high-order shear deformation plate theory (HSDT). The effects of skew angles and ply orientations on the natural frequencies for various boundary conditions are studied using a nonlinear high-order finite element program developed for this study. The numerical results are in good agreement with those reported by other investigators for simple test cases, and the new results reported in this paper show the interactions between the skew angle, layup sequence and cutout size on the free vibration of the laminate. The findings highlight the importance of skew angles when analyzing laminated composite skew plates with cutout or without cutout.

The purpose of this research is to present basic data for the residents, experts, and administrators to establish sustainable and future-oriented experience villages by investigating the operational realities of rural and mountain experience villages that have currently been promoted as the government-supported projects. First, in order to establish a sustainable experience village, each of the residents, experts and administrators who are the principal agents for cultivating the village should perform their role appropriately and build an organic cooperative system. The residents should have a sense of ownership and form a sense of solidarity by organizing communal consultation system. The experts should be able to present feasible project plans. The administrators need to have posture of understanding from the viewpoint of residents. In order to establish sustainable experience villages, ecological, cultural, and social values should be conveyed preferentially, and through this, the living spaces like farm villages should be formed.

Citrus farming become one of highly potent area for the farmer s income in the Asia region. Because of its favorable taste and distinctive aroma, attractive color, and nutritional values, market demand has increased steadily along with the income increases in the region. However, realization of the potent have been constrained due to poor orchard management, frequent occurrences of pest and diseases, and a high cost in production besides of the market failures. Cutting down of production cost should be an operational goal to obtain mope profit where marketing structure has yet been underdeveloped. The objective of this study was to provide a comparative information to those program efforts of searching comparative advantage in production. For the three countries, reduction of labor cost by reduction of chemical application frequency was recommended while pursuing further mechanization in those operation such as in pruning, harvesting and pest control. Adoption of the IPM (integrated pest management) will be useful to reduce the number of spraying chemicals with changed knowledge and attitude of the farmers.

Changing environments in agricultural business make it necessary to promote the cooperative farming system so as to scale up farming size, which may contribute to increasing competitive power. Therefore, rural and fishery development program was established in 1990 to encourage individual farmers to jointly form the agricultural company or farming cooperatives. However, while the number of agricultural corporations has rapidly increased through the governmental support, their business achievements become worsening mainly resulting from unplanned and careless management practices. This paper suggested following strategies for management process reengineering to improve the efficiency of agricultural corporations; challenging business initiatives to enlarge volume of sales amounts, maintaining the optimal level of participants and physical assets for cost savings, and proper use of information technology and consulting agencies.

South and North Korean fisheries cooperation has not been attained since 1950's political situation, and the major fishery resources of Korean peninsula also has not been cooperatively managed by South and North Korea. Furthermore, the species inhabiting the Korean peninsula region with commercial value are usually maintaining the single ecosystem which requires for cooperative management of fishery resources for continuous fishery. Therefore, in order for South and Korean fishery industry to develop the political situation to a rational direction, present condition of North's fishery industry must be accurately understood and acknowledge in its point of issues, also as level to prepare for future unification, reform and reaction of long-termed and well organized South and North's fisheries program must be arranged.

철도 운전사고의 대부분을 차지하는 철도건널목에 대한 기존의 사고예측식은 국외의 경우 Peabody Dimmick Formula, New Hampshire Index, National Cooperative Highway Research Program(NCHRP) report 50, U.S. Department of Transportation(DOT) 사고예측식 등을 이용하고 있었으며, 국내의 경우, U.S. DOT 사고예측식의 입력변수를 다변량 분석법을 이용하여 국내에 맞게 조정한 사고예측식을 이용하고 있다. 그러나 위에서 제시한 철도건널목 사고예측식은 철도건널목에서 발생하는 사고를 단순히 철도통행량, 도로통행량, 선로수, 도로수 등의 요인에 국한하여 분석한 것이고, 사고예측식 자체가 철도건널목에만 국한된다는 맹점을 안고 있어서 철도건널목장치라든지 철도건널목을 이용하는 사람들의 성향 등, 여러 인자를 고려한 철도건널목에서의 안전성분석 및 대책을 제시할 필요가 있다. 본 논문에서는 철도건널목장치를 포함하여 다른 시스템에도 범용적으로 적용할 수 있고, 제한된 변수에만 국한하지 않아 여러 사항을 고려할 수 있는 안전성분석 절차를 제시하였는데 이 안전성 분석 절차를 철도건널목에 적용함으로써 시스템의 위험요인을 분석하고, 이에 대한 원인 및 결과, 손실을 도출한 후 대책을 제시할 수 있었다.

In this paper, we present POSSDM (POSTECH Situation-Based Dialogue Manager) for a spoken dialogue system using a new example and situation-based dialogue management techniques for effective generation of appropriate system responses. Spoken dialogue system should generate cooperative responses to smoothly control dialogue flow with the users. We introduce a new dialogue management technique incorporating dialogue examples and situation-based rules for EPG (Electronic Program Guide) domain. For the system response inference, we automatically construct and index a dialogue example database from dialogue corpus, and the best dialogue example is retrieved for a proper system response with the query from a dialogue situation including a current user utterance, dialogue act, and discourse history. When dialogue corpus is not enough to cover the domain, we also apply manually constructed situation-based rules mainly for meta-level dialogue management.
