In case of high-tech process industries such as semiconductor and TFT-LCD manufactures, fault of a virtually finished product that is value-added one, since it has gone throughout the most of processes, may give rise to quality cost nearly amount to its selling price and can be a main cause that decreases the efficiency of manufacturing process. This paper proposes a real-time dispatching algorithm for semiconductor manufacturing process with rework. In order to evaluate the proposed algorithm, this paper examines the performance of the proposed method by comparing it with that of the existing dispatching algorithms, based on various experimental data.

In this paper, we study the network structure that can guarantee the end-to-end quality of service in the Explicit multicast network. In order to guarantee the end-to-end quality of service, we adopt the end-to-end measurement based admission control (EMBAC) scheme. For the effective measurement of the network state and minimum influence on the current data traffic, the queue structure, which the drop precedence in assured forwarding (AF) Per hop behavior (PHB) of the differentiated service (Diffserv) is applied to, is proposed. Through a simulation, we show that EMBAC can make tile controlled load service in tile AF PHB applied Xcast network, and the qualify of the admitted traffic is guaranteed. In addition, the performance of the EMBAC is changing according to the selling parameter of AF PHB.

South Korea has allowed parallel importation since 1995. Parallel importation causes competition among importers in the logistics process allowing, consumers to purchase foreign brand products at low prices. Most parallel importers base product pricing on subjective judgements. Fashion products in particular, have different sales rates depending on trends and seasons, so sales performance varies greatly depending on selling price timing and policy. The merchandiser (MD) set the price on parallel importation products by aggregating information on imported products and pricing goods. However, this customized process is very time consuming for the MD. This is because the logistics process of parallel importation's customs clearance procedures and repair works is complicated and takes a significant amount of time. In this paper, we propose an improved parallel importation logistics process based on big data, which automatically sets the price of parallel importation products.

Clean Technology goes beyond Clean-UP (or "End of PiPe) Technologies to include Pollution prevention, waste minimisation, and cleaner production. However, the concept of Clean Technology goes deeper than changes in technology, to ways in which human needs can be satisfied sustainably. In other words, Clean Technology, concentrates on delivering a human benefit rather than making a product. Introducing cleaner technology may therefore involve new commercial relationships as well as new technological practices. In some economic sectors, this involves leasing or providing a service rather than selling a product. Life Cycle Assessment (LCA) is an important tool in Clean Technology. LCA involves determining all the resources used and all the wastes and emissions produced in providing the human benefit. Use of LCA ensures that improved environmental performance in one part of the Life Cycle is not achieved merely at the expense of more environmental damage elsewhere. Going beyond LCA, the concepts of Life Cycle Design and "metabolised" use of materials are approaches to obtain maximum benefit from materials as they pass through the human economy. "Closed-loop" use can be a component of clean technology. Looking beyond simple re-use and recycling, a material may pass through a "cascade of uses". typically a series of applications with progressively lower performance specifications. Closed-loop use necessarily involves a change in commercial practice, because the material or product must be recovered after use.

This study carried out a horticultural program for people with mental disabilities to determine suitability of the horticultural activity program and to actually apply to vocational rehabilitation. The program was carried out in 16 sessions from April 12 to June 7, 2018 with nine people with a strong will to participate in vocational rehabilitation at a health center for persons with mental disabilities. The tools used were the Horticultural Activity Performance Assessment (psychological behavior) and Purdue Pegboard Test that examines functions of hands and arms. The subjects sold the products they made during class time and obtained the profits. After the program, the scores increased with a significant difference (p = .000) in the psychological behavior area of the Horticultural Activity Performance Assessment. Hand and arm movement also showed continuous improvement along the program with a significant difference (p = .000), as well as finger dexterity also with a significant difference (p = .018). The net profit was 314,000 KRW (subtracting cost of goods 314,000 KRW from total sales 628,000 KRW). The profit was shared equally among the nine subjects, each receiving 34,900 KRW. Therefore this study proved horticultural activity class is suitable for vocational rehabilitation of people with mental disabilities proved by the positive effects. We also expect that the subjects will be able to make more profits if they learn more skills, since they are interested the process of making such profits.

정부지원 중소기업 R&D 과제의 기술적 성공률과 사업화 성공률 간에 큰 격차 발생요인을 규명하기 위해 정부지원 중소기업 R&D과제의 기술지향성이 기술적 성과에 미치는 영향과 기술적 성과가 사업화 속도에 미치는 영향을 분석하였다. 그 결과 기술지향성이 기술적 성과에 부(-)의 영향을 미치며 기술적 성과는 사업화 속도에 정(+)의 영향을 미치는 것으로 나타났다. 기술지향성이 낮은 과제가 정부의 지원 대상으로 선정되면 계획한 목표달성을 기준으로 한 정부의 평가에서 쉽게 성공판정을 받을 수 있어, 기업 독자적 R&D와 대조적으로 90%대의 성공률의 보이며 사업화에 쉽게 착수하고, 속도도 빠르다는 것이다. 이는 중소기업이 R&D 과정에서 필요로 하는 사항을 반영하지 못한 정부의 중소기업 R&D지원시스템에서 비롯되고 있는 것으로 나타났다. 다만, 본 연구는 정부의 2009년 지원, 2010년 기술적 성과, 2011년 사업화 조사결과 자료로 수행함에 따라 최근 상황을 반영하지 못한 한계가 있다.

The purpose of this study is to investigate consumer perception and importance of food tourism properties and performance of the properties in Sangju province of Gyeongsangbuk-do. The study has found that persons who have food tourism experiences (75 persons, 50.7%) had slightly more than not experience persons (72 persons, 48.6%). Additionally, most of the respondents were usually satisfied with the local foods. Also, it was found that food tourism had been taken 1-2 times per 6 months (48 persons, 64.0%) on average, and 135 persons (91.2%) had intention of experiencing food tourism. According to the result of Importance-Performance Analysis (IPA) on consumers' food tourism properties, high importance was on 'There are attractive landscapes.' ($4.52\;{\pm}\;0.56$), 'Accommodations with reasonable price.' ($4.18\;{\pm}\;0.80$), and 'The food of the area is famous.' ($4.15\;{\pm}\;0.73$); and the properties such as 'There are local specialty shops or markets selling local produce.' ($3.03\;{\pm}\;0.83$), 'The climate is temperate.' ($3.03\;{\pm}\;0.87$), and 'There are attractive landscapes.' ($3.02\;{\pm}\;0.98$) showed average performance. A factor analysis about consumers' importances to the food tourism properties shows that the factors were divided into four kinds and each of the factors were named as 'convenience-stable propensity', 'valued-oriented propensity', 'adventurous-aggressive propensity' and 'traditional-active propensity'. Variance ratios of each factor were 22.319%, 10.286%, 8.723% and 6.239%, respectively. According to the result of a reliability analysis, Cronbach's alpha value was 0.8621, implying that reliability of each item was very high. Therefore, it is considered that development of food tourism products and promotion strategies therefore should be designed based on the importance of food tourism properties hereafter.
