In this paper, a optimal designing methodology is proposed to determine the parameters for skip-lot sampling plan of type SkSP-2 plan with double sampling plan as reference plan, when the lifetime of the product follows generalized exponential distribution. The two points on the operating characteristic curve approach are used to find the optimal parameters for the proposed plan. The plan parameters are determined so as to minimize the average sample number subject to satisfying simultaneously both producer and consumer risks at the acceptable and limiting quality levels respectively.

As time goes by, the market demand increases and each LCD panel manufacturing company makes every effort to produce more panels in a limited time. It is necessary to reduce the cost and time of production for the improvement of productivity in manufacturing companies. The increased speed of thin films growth used in the TFT process brings improvement of productivity but it is also accompanied by a drop in display quality due to a characteristic change of the thin film. So in our dissertation, we deal with the increased speed of a-Si layer growth and the proportioned a drop in characteristic quality. We discuss a drop in display quality by a characteristic change of a-Si layer and we propose a counter-plan through panel design improvement. We have already applied our plan to the 15" XGA panel and confirmed the improved result.

After 18th century in Korea, a tendency of the traditional folk houses shows not only the typical types but also the cultural areas in terms of each regional part. The existing folk houses are selected in order to compare the characteristic of the plans with those of the central region in Korea. Moreover this region has been a collided zone of culture and military from the old period of the Three Kingdoms, because the district of Che-chun is located between the southern part and the central one. So its culture and housing plan showed as unique forms, so-called the Culture of Frontier and Composite. Consequently the purposes of this study are to grasp the characteristic of those plans and to compare the plan types with ones of the central region. For the attainment of the above goal, this investigated study is prosecuted by means of the existing 6-folk houses in Che-chun city.

Coworking space is the ideal concept of small companies, freelancers, startups, and entrepreneurs operating out of a shared office space while working independently of one another. The coworkers share the core values of coworking: collaboration, openness, accessibility, sustainability, and community. Little academic research has been completed on the composition of coworking spaces and the businesses that use them. The purpose of this study is to examine the organization and characteristic of coworking space based on domestic and international cases for providing basic data on the coworking space plan. This study examined existing academic literature, media, online sources to assess the environmental background of worldwide coworking space, the current status, conceptualization, and membership plan that can be appled coworking spaces. The case study for coworking space is limited to the space where there is web site that is showed floor plan. Coworking spaces are designed to be environmentally friendly, offering common area with many facilities to encouraging community and collaboration. For creating ideal coworking space, the concept of coworking space must be recognized as a community space for interaction and creativity between people and space. Based on the result of this study, the appropriate zoning, circulation and specific floor plan of coworking space is needed for the next research.

The purpose of this study is to find out the plan type of traditional folk housing in Jeoun-Nam Province. The building time of these houses is mainly from early 19C to early 20C and about 1,000 houses have been investigated. The conclusion of this research is 1. Small house is composed of kitchen, one or two rooms and Marae(the place of storage and sacrificial rite). Big house has one more room and one more storage in comparison with the small house. Marae and Jeoungjibang(a room which is in front of kitchen) are characteristic rooms of folk house in Jeoun-Nam Province. 2. The plan type varies in Jeoun-Nam Province. '-'type is a main type of layout and it is arranged a kitchen, a big room, a Marae and a small room in order. In the big house, jeoungjibang(the third room) is added. 3. In the southwestern Island area, no room is arranged beside Marae. Marae has characteristic confucian order because it is the place of sacrificial rite. Therefore there is a great difference in comparison with other area. 4. In the mountain area such as Gurae, there are some houses which have two rooms arranged up and down in one side; that is, upside is Marae and downside is small room. This type is called Kyump Jip.

This primary study describes some proposition of restoration and rehabilitation of rail station and station impact area for efficient use. Therefore, I reviewed the functions and roles about rail station and other railway facilities related with urban structures and development, and also analysed the case studies about realignment of rail station, and then, suggested primary management plan of efficient railway installation. This study has some bounds and limits owing to the descriptive reviews but not detailed analyses. Hereafter, I am planning to consider the management plan for efficient railway installation use as coinciding with specific city characteristic and comprehensive plan such as rearrangement of the station.

The general formulas of the operating characteristic(OC) function, average sample number(ASN) and average outgoing quality(AOQ) for the modified n-level skip-lot sampling plan(MMSkSP2) were derived using Markov chain properties by Cho(2008). In this paper, the OC curve, ASN and AOQ of a reference plan, modified two-level, three-level and five-level skip-lot sampling plans are compared.

이 논문의 목적은 영국의 마을단위 계획인 근린생활권 계획 수립 정책을 공동체 파트너십 특성을 중심으로 살펴보는 데 있다. 영국 근린생활권 계획에서 공적 파트너십의 특징은 공동체가 계획 수립 전 과정에 걸쳐서 참여하고 있다는 점이다. 또한 이를 법적으로 의무화시키면서 공동체 참여를 유도하고 있다. 또한 근린생활권 계획 수립과정에서 주민투표 제도를 도입해서 최다수의 선택이 최선의 방법임을 강조하고 있다. 이는 제도적 차원에서 공동체를 가장 적극적으로 참여시키는 방안이다. 영국 사례가 남긴 중요한 사실은 지역 공동체 발전에 있어서 경제적 교리를 초월하여 사회경제로의 진화를 강조하고 있으며, 그리고 이러한 사회경제로의 진화는 보다 포괄적인 시각에서 공동체 파트너십과 깊은 관련이 있다는 것이다.

Traditional acceptance sampling plans have focused on the proportion of nonconforming items as an attribute criterion for quality. In today's modern quality management under high quality production environments, the reduction of the deviation from a target value in a quality characteristic has become the most important purpose. In consequence, various inspection plans for the purpose of reducing the deviation from the target value in the quality characteristic have been investigated. In this case, a concept of the quality loss evaluated by the deviation from the target value has been accepted as the variable evaluation criterion of quality. Further, some quality measures based on the quality loss have been devised; e.g. the process loss and the process capability index. Then, as one of inspection plans based on the quality loss, the rigorous design procedure for the variable sampling plan having desired operating characteristics (VS-OC plan) indexed by the quality loss has been proposed by Yen and Chang in 2009. By the way, since the estimator of the quality loss obeys the non-central chi-square distribution, the rigorous design procedure for the VS-OC plan indexed by the quality loss is complicated. In particular, the rigorous design procedure for the VS-OC plan requires a large number of the repetitive and complicated numerical calculation about the non-central chi-square distribution. On the other hand, an approximate design procedure for the VS-OC plan has been proposed before the proposal of the above rigorous design procedure. The approximate design procedure for the VS-OC plan has been constructed by combining Patnaik approximation relating the non-central chi-square distribution to the central chi-square distribution and Wilson-Hilferty approximation relating the central chi-square distribution to the standard normal distribution. Then, the approximate design procedure has been devised as a convenient procedure without complicated and repetitive numerical calculations. In this study, through some comparisons between the rigorous and approximate design procedures, the applicability of the approximate design procedure has been confirmed.
