  • 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.

  • 누에(Bombyx mori)번데기는 창상치료용 드레싱, 간보호활성, 항유전독성, 포도당농도 조절, 항암활성 등에 다양하게 적용되고 있다. 본 연구에서는 붉은동충하초(Cordyceps militaris)를 이용하여 발효시킨 누에번데기분말의 에탄올 추출물(Ethanol extract of silkworm pupae fermented with Cordyceps militaris, ESfC)의 항비만효능을 분석하기 위하여, SD랫드로부터 분리된 일차지방세포(Primary adipocytes)에서 농도별로 ESfC를 처리하여 free glycerol release, cAMP농도를 측정하였고, 고지방사료(High fat diet, HFD)가 처리된 C57BL/6N 비만마우스에 ESfC를 투여하여 지방조직과 간조직에서 지방축적(Fat accumulation)을 관찰하였다. 먼저, 지방감소효과를 나타내는 지표물질로서 cordycepin의 존재는 HPLC분석을 통하여 ESfC에서 확인하였다. 또한, free glycerol수준과 cAMP농도는 고농도 ESfC가 처리된 일차지방 세포에서 유의적으로 증가하였지만 이들 수준은 저농도와 중농도의 ESfC로처리세포에서는 유의적인 변화가 없었다. HFD-유도 비만모델에서, 고지방사료의 투여에 의해 유의적으로 증가된 지방무게와 지방세포의 크기는 ESfC처리그룹에서 감소되었다. 간 무게와 지방방울(Lipid droplet)의 수는 고지방사료의 투여에 의해 증가하였지만 ESfC투여에 의해 유의적으로 감소하였다. 또한, 유사한 회복효과는 perilipin과 HSL의 인산화 수준뿐만 아니라 ATGL의 발현수준에서도 관찰되었다. 따라서 이상의 결과는 ESfC가 지방일차세포에서 지방분해를 촉진하고, HFS유도 비만모델에서 지방 축적을 억제하는 효과를 나타냄을 보여주고 있으며, 향후 비만환자에 처리하기 위한 약물로서 사용가능성을 제시하고 있다.

  • 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.

  • 금융서비스산업 전반에 고객의 금융정보 및 금융서비스를 적절하게 보호하고 유지하기 위해, 조직은 정보보호 관리체계(ISMS), 개인정보보호 관리체계, 비즈니스연속성 관리체계와 같은 경영시스템을 도입하여 운영하기 시작하였다. 본 연구는 금융권이 ISMS를 고려하는 것이 바람직하며 정보보안 문화, 실무 및 가이드라인을 고려하는 다양한 조직 안에 각기 다른 형태를 가질 수 있다는데서 출발하였다. 금융서비스산업 내에서도 분야에 상관없이 적용 가능하고 보편적으로 널리 알려진 국제 정보보호 관리체계 ISO27001을 도입한 금융 관련 조직을 대상으로 인증 심사에 따른 부적합 추이 및 통제 요인의 분석을 통해 해당 ISMS의 주요 통제 영역을 도출하게 된다. 이에 따라 ISMS를 도입하여 운용하고 있는 금융 관련 5개 조직의 사례분석을 통해 정보보호 수준의 개선 효과를 분석해 보고자 했다. 금융 섹터에서 인증을 유지하고 있는 곳이 적어 실증 연구를 위한 자료 확보가 어려웠지만, 초기 연구 대상으로서의 의미가 있는 것으로 분석되었다. 분석을 통해, 대상 업체들에서 최초심사로부터 3년 주기가 지나는 동안 부적합 건수가 매년 감소하고 있음을 확인할 수 있었다. 부적합 빈도수가 가장 높았던 물리적 환경적 보안, 의사소통 및 운영관리, 접근통제 영역이 각 23%, 19%, 17%를 나타내 전체 부적합의 59% 정도를 차지하는 주요 통제영역으로 도출되었다. 이를 통해 금융권에서 중요하게 다루어지지 않았던 기술적, 관리적, 물리적 보안 이슈를 ISMS가 충족시키고, ISMS가 금융서비스산업에 적용 가능한 효과적인 관리체계가 될 수 있음을 발견하였다.

  • 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.
