  • A completely separated functional FMS (Flexible Manufacturing Systems), or a partly separated functional FMS, should be constructed because a fully functional FMS, where each machine has all of the tools required for procesing various kinds of jobs, is superflous and wasteful in meeting the multiform and changeable demands of comsumers in a flexible manner. The effective methods are presented in this study for allocating the tools to each machine in a two-machine flow shop type FMS to meet the above demands and to maximize the utilization of the FMS. The methods for a completely separated functional FMS having no duplicated tools and a partly separated functional FMS having some duplicated tools are proposed in this paper. Some simulation results clarify that utilization of the FMS by this methods is as high as the fully functional FMS when the number of jobs is large.

  • A split-column photobioreactor (SC-PBR), consisting of two bubble columns with different sizes, was developed to enhance the photon utilization efficiency in an astaxanthin production process from Haematococcus lacustris. Among the two columns, only the smaller column of SC-PBR was illuminated. Astaxanthin productivities and photon efficiencies of the SC-PBRs were compared with a standard bubble-column PBR (BC-PBR). Astaxanthin productivity of SC-PBR was improved by 28%, and the photon utilization efficiencies were 28-366% higher than the original BC-PBR. The results clearly show that the effective light regime of SC-PBR could enhance the production of astaxanthin.

  • The effective fermentation methods of Kimchi juice for utilization of outer layer of Chinese cabbage, an waste of Kimchi industry were studied. The Kimchi juice prepared with brining and grinding the waste of Chinese cabbage and addition of spices was fermented at $25^{\circ}C$. Addition of 5$^{\circ}C$15% fermented Kimchi juice of pH 5.4 at initial stage and pH 4.4 at middle state resulted in a significant increase in fermentation rate and solid content after 12 hours of fermentation. The combined method of enzymatic hydrolysis(0.1% viscozyme) of the brined and ground cabbage and addition of 2.0% NaCl, 1.0% sucrose and 10% fermented juice of pH 5.4 first and 4.4 during fermentation, respectively resulted in more rapid fermentation. The solid concentration was 5 times higher than control at maximum point and acidic and total flavor intensity were also significantly high.

  • This paper diagnosed the assessment problems and development types of the simple statement of the Sea Area Utilization Consultation System. and suggested the key assessment items for system improvement. The major types of Public Water occupation and use, and distribution characteristic of regional and coastal were analyzed by evaluate 529 review items during 2010-2012. The artificial structure installation including harbor and fishing port facilities in the South and West coast, and seawater supply and drainage for land-based aquaculture and power plant were dominated. The checklists considering each types of occupation and use in Public Water were suggested. In addition, policy proposals for system improvement were suggested.

  • De facto standards can be divided into the U.S. group standards' and 'forum and the consortium standard. mainly applies to high-tech industry forums, and a consortium standard of the industry given the nature of the standard are frequently revised, the country Due to the introduction of standard time. Economic loss to consider when in reality, the introduction of national standards of the United States is limited to the desirable standard, and the fact the actual award of standards, national standards, or if you want to introduce standard, each of depending on the type of attitude and strategy for standards by category, based on the characteristics of each body strategy and are needed. Through this study on utilization of de facto standards for national standards, it is researched that major de facto standards bodies status and domestic industrial fields which need utilization of de facto standards for national standards. Through overseas Case, effective usage of de facto standards will be obtained.

  • China is the largest rice producer in the world, with about 28 million hectares rice-planting area. Most of the rice is consumed domestically as daily staple food, with a small proportion consumed as feed and deep-processed products. The low elastic elasticity and low profit of rice production which hampers the development of the industry, is due to the low quality of rice grain, low processing level and undeveloped rice processing technique. Promotion of high-quality species, effective quality control, adoption of modem Processing techniques, My use of low-quality indica rice, and utilization of specialty rice are considered as priorities in rice industry.

  • In cognitive radios, exponentially distributed idle period(EIP) is considered in this paper. In the EIP case, durations of idle periods are be limited and varied by primary traffic arrivals. Accordingly, we first analyze the idle period utilization which can be achieved by the slotted ALOHA in cognitive radio communications. The idle period utilization is a newly defined performance metric to measure the transmission performance of the secondary network as effective time durations utilized for successful secondary transmissions in an idle period. Then, the idle period utilization is maximized through controlling the data transmission time. All technical processes are mathematically analyzed and expressed as closed form solutions.

  • The purpose of this study is to identify the interorganizational factors that influence both the supplier-buyer's EDI utilization and the business performance in domestic retail industry. In terms of successful supply chain implementation and operation, we deduced the structural factors in the context of the interorganizational characteristics between mass merchandisers and vendors. This study therefore focused on suggesting the ways of managing the partnership in supply chain and conceptualizing the big picture of EDI development model in the scope of a retailer's IT strategy. This paper implicates that it is important to leverage the level of organizational capabilities for the success of supply chain adoption and operation. In the stream of SCM initiatives from the manufacturing industry, retailers should concentrate on improving the interorganizational environment and implementing the effective information technology for supporting business strategy.

  • This study was designed to analyze farmers' behavior on dealing with secondhand agricultural machinery and to device proper measures for promoting utilization of secondhand agricultural machinery. This objective was accomplished by using data which were analyzed, collected through questionnaires from 35 farmers on dealing with secondhand agricultural machinery. The main, realistic measures for promoting utilization of secondhand agricultural machinery, based on farmers' behavior, are as fellows: First, to make and offer a criteria fer evaluating the optimal price of secondhand agricultural machinery, which should be a effective measure for promoting farmers' dealing with them. Second. to establish a store to exhibit and sell secondhand agricultural machinery. This is the most important way to promote dealing with them. In the process of political supporting to establish the store, the equality of opportunity should be adopted to every organization want to deal secondhand agricultural machinery. Third, to strengthen financial supports for buying secondhand agricultural machinery and to assure A/S system.

  • The need for effective information systems that can help in efficient transportation management has become essential. This study presents the potential benefits of developing a decision support system used by a trucking company for routing and scheduling. Our study investigates how customer exibility factors affect the utilization of transportation resources and establishes a vehicle scheduling model for better allocation of transportation resources with a time window. The results show vehicle savings from 25% up to 70% per day given different levels of exibility in delivery times. Increased capacity utilization can be achieved by considering only customer exibility in the model. Our study implies that incorporating customer exibility into the information system can help transportation organizations have the capability to gain control over management to cut costs and improve service.
