Recently, color proofing in printing industry grow rapidly. If an order decide color from known color information in the case of color reproduction, we can reduce expenses and time. In color proofing the best important point must be closed proofed color to primary color and secondary color. Model-based approaches have the advantages of faster recharacterization and the opportunity of simulating product enhancements such as changes in ink properties and halftoning. In this paper, we transformed the dot area of CMYK to CIELAB color space using color reprodution models. Firstly, we measured spectral reflectance of primary color printed by Matchprint II and the data was used to find tone reproduction curve using regression equation, and than we applied at primary color model, such as Murray-Davies, Yule-Nilsen, and mixed color model, such as Kubelka--Munk, relaxed version of spectral Neugebauser. In such results, the Kubleka-Munk model resulted in the best spectral reconstruction accuracy followed by relaxed version of spectral Neugebauer model, color difference is 2.8401.

Silkworm (Bombyx mori) pupae have been widely worked in wound dressing, hepatoprotective activity, antigenotoxicity, control of glucose level and anti-cancer activity. To investigate the anti-obesity activity of ethanol extract of silkworm pupae powder fermented with Cordyceps militaris (ESfC), the free glycerol release and cAMP concentration as well as fat accumulation were measured in the primary adipocytes of SD (Sprague Dawley) rats and high fat diet (HFD)-treated C57BL/6 mice treated with 12 weeks. Firstly, the presence of the cordycepin with lipid lowering effect was confirmed in ESfC using HPLC analysis. The level of free glycerol and cAMP concentration was significantly increased in the primary adipocytes treated with high dose of ESfC ($400{\mu}g/ml$) although these levels were consistently maintained in other dose ESfC treated groups. In HFD-induced obesity model, the increased fat weight and size of adipocytes in HFD+Vehicle treated group was recovered in HFD+ESfC treated group. Also, the liver weight and the number of lipid droplets were higher in HFD+Vehicle treated group than No treated group. But, this level was significantly decreased in HFD+ESfC treated group compared with HFD+Vehicle treated group. Furthermore, a similar recovery was detected on the phosphorylation of periliphin and HSL, and ATGL expression. Overall, the results of the present study provide some scientific evidences that ESfC can stimulate lipolysis in primary adipocytes and prevent fat accumulation in HFD-treated obesity model, and therefore have the potential for use as anti-obesity agents to treat obese patient.

The primary aim of this research is to summarize and discuss the problems that the hand tool manufactiuring industry of Korea is now facing. The study was performed mainly through the interviews with hand tool industry experts. Traditional design concepts are usually oriented towards the functionality of tools but often ignore the human factors such as ease of use, comfort, etc. As a result, for hand tools, mechanical and material aspects have been considerably enhanced but human factors have still much room for improvement.

The importance of noodles in Korean diet is becoming greater in recent years. This article is an overview on a variety of Korean noodles including dried noodle, naengmyeon (buckwheat noodle), dangmyeon (starch noodle) and instant fried noodle. It gives also the background information on the changes of the definition of noodles. Since Koreans are the largest consumer of instant fried noodles per capita in the world, primary emphasis was placed on the development history of instant fried noodles.

Financial service industry has introduced and operated management systems such as information security management system (ISMS), personal information security management system, business continuity management system to protect and maintain suitably customer's financial information and financial service. This study started that it's desirable financial industry takes consideration of ISMS and it can be different types among various organizations taking consideration of culture, practical work, and guideline of information security. The study derives primary control areas of ISMS through analyzing non-conformity trends and control factors according to certification audit for finance-related organizations introduced international ISMS of ISO27001 which is well known and commonly applicable irrespective of areas in financial service industry. Through case analyses for five finance-related organizations operating ISMS, this study analyzed improvement effects of ISMS. It has a meaning as an initial research though it was difficulty in acquiring data for empirical study because of rare organizations maintaining certification in financial sector. As a result, number of non-confirmity from the first audit to three years' elapse was decreased every year. Physical and environmental security, communication and operations management, and access control having the highest frequency of non-conformity each presented 23%, 19%, and 17%, which reached 59% in total and they are derived into primary control areas. ISMS can fulfill technical, managerial, physical security issues, which have not been treated importantly in financial industry. In addition, this study presented that ISMS can be an effective management system applicable for financial service industry.

Under U.S. Antidumping law, dumping occurs when 'subject merchandise' is imported into the United States and sold at less than 'fair value'. The administration of U.S. antidumping law is shared between the U.S. Department of Commerce(USDOC) and the U.S. International Trade Commission(USITC). USDOC's task is to determine whether imports are being dumped, and if so, to estimate the margin of dumping. In determining whether an industry in the United States is materially injured or threatened with material injury, or the establishment of an industry in the United States is materially retarded, by reason of the subject imports, the USITC must first define the 'like product' and the 'domestic industry'. One of the crucial factors on antidumping measures is the interpretation's scope of the 'like product' and the 'domestic industry', leading the most controversial issues in U.S. antidumping law. The primary purpose of this paper is to examine the 'domestic industry' and 'like product' considering U.S. antidumping law. Most USITC's determinations regarding like product and industry as flexible conception have been supported by the U.S. Courts.

Compared to LC resonance, LCL resonance has distinct advantages such as a large resonant capability, low voltage and current stresses of the power device, constant voltage or current output characteristics, and fault-tolerance capability. Thus, LCL resonant compensation is employed for a movable Inductive Contactless Power Transfer (ICPT) system with a multi-load in this paper, which achieves constant current output characteristics. Peculiarly, the primary side adopts a much larger compensation inductor than the primary leakage inductor to lower the reactive power, reduce the input current ripple, generate a large current in the primary side, and realize soft-switching. Furthermore, this paper proposes an approximate resonant point for large inductor-ratio LCL resonant compensation through fundamental wave analysis. In addition, the PWM control strategy is used for this system to achieve constant current output characteristics. Finally, an experimental platform is built, whose secondary E-Type coils can ride and move on a primary rail. Simulations and experiments are conducted to verify the effectiveness and accuracy of both the theory and the design method.

This paper examines export promotion plans of digital content industries, particularly of game, animation & character industry based on the OSMU(One-source Multi-Use) strategy. As the digital content industry is one of the newest industries as a source of strategic export, we must promote the export of digital contents that hold so much international competitiveness and through that promotion, we have to strengthen the international competitive power. The game, animation & character contents are very easy to adapt each other for creating new contents by omnidirectional OSMU. Therefore, it is intended to present some primary factor for export promotion of game, animation & character contents through the OSMU strategy.
