  • It is widely accepted that the reading mechanism of Super-RENS(super-resolution near field structure) and Super-ROM(super-resolution read only memory) is closely related with non-linear temperature dependent material properties such as refractive indices, phase change. Furthermore, the dynamic change of the temperature distribution also an essential part of reading mechanism of Super-RENS/ROM. Therefore, the knowledge of the temperature distribution as a function a time is one of the important keys to reveal the physics of reading mechanism in Super-RENS/ROM. We calculated time-dependent temperature distribution in a 3-dimensional Super-ROM disk structure when moving laser beam is irradiated. With a help of commercial software FEMLAB which employed finite element method, we simulated the temperature distribution of ROM structure whose pit diameter is 120-nm with 50-nm depth. Energy absorption by moving laser irradiation, time variations of heat transfer processes, heat fluxes, heat transfer ratios, and temperature distributions of the complicate 3-dimensional ROM structure have been obtained.

  • It is important that overheat protection of super heated tube in boiler operation and maintenance. The overheat of super heat tube can make damage and rupture of tube material, which causes accidental shutdown of boiler. The super heated tube overheat is almost due to the lack of uniformity of gas temperature distribution. There are two ways to protect overheat of super heated tube. The one is to control hot gas operation pattern which is temperature or flow distribution. the other is to control super heated steam flow distribution. The former is difficult than the later, because of control device design. In this paper steam flow control method which uses orifices is proposed to protect overheat of super heat tube.

  • Purpose - The purpose of this study is to investigate the factors that cause consumers to frequently visit large - Super Store and goods for large - scale retailers using Super Store. Research design, data, and methodology - The purpose of this study is to present the empirical analysis of 53 adult males and females living in the Mokpo area on the relationship between perceived level of satisfaction and loyalty of the large - scale marts. The results were analyzed. The statistical data of the questionnaire were verified by the SPSS. Results - In the empirical analysis of this study, four variables were found to be the main loyalty factors, which were found to affect the satisfaction of Super Store and the decision to return again. Therefore, in this study, the quality of goods, price, diversity, and image were analyzed as loyalty factors, and it was analyzed as factors influencing satisfaction. It was confirmed that loyalty factors were important. In particular, consumers' perception of behaviors such as local specialties and community service that can be distinctly differentiated from other distribution agencies was very low. Conclusions - It is necessary to construct a comprehensive systematic system to analyze the detailed factors influencing the satisfaction and loyalty of users of Mokpo ticket consumers and to systematically manage and evaluate them. In order to raise awareness of consumer loyalty factors, consumer satisfaction and loyalty survey should be regularly conducted. Consumers should look for ways to improve them and develop improvement plans. The various direct and indirect services provided by Super Store to consumers include price, quality, assortment, customer service, accessibility, and feelings for large marts. However, since the services provided by the Super Store are different from those of the consumers, the loyalty factors for the different factors can be different. Therefore, in order to differentiate them from traditional markets or other distribution centers, it It should be used as a weapon of competition. In this study, it is generally recognized that the services provided by Super Store are very simple and inexpensive, so that consumers are not aware of the difference of particular stores.

  • The corrosion resistance of super duplex stainless steel on both its fibrous and dispersed phase was investigated. These structures consist of various volume fraction and distribution of austenite structure, which were obtained by changing the heat treatment temperature and cycle. The fibrous phase had higher austenite volume fraction than that of the dispersed phase at the same temperature. Corrosion resistance of super duplex stainless steel was evaluated through an immersion test and an impingement test, using 35% HCI and sea water, respectively. Super duplex stainless steel was compared with STS316L and STS304. The corrosion resistance of super duplex stainless steel was superior to ST316L and STS304. The dispersed phase of super duplex stainless steel was more stabilized than the fibrous phase in corrosion. The magnitude of corrosion rate was in order STS304, STS316L, fibrous phase of super duplex stainless steel and dispersed phase of super duplex stainless steel.

  • 저작권의 거래 및 통제를 매우 낮은 비용으로 구현한 DRM(Digital Right Management)에 의해 디지털 컨텐츠의 유통에 획기적인 변화가 가능할 것으로 생각된다. 본 논문은 DRM 기술의 도입에 의해 개별 이용자가 유통의 주체가 되는 초유통(Super Distribution)의 적용 가능성과 다양한 가격설정 방식이 적용될 수 있다는 점에 주목하였다. 우선 초유통을 통해 이용자들의 정보획득비용을 감소시키고 이를 통해 수요를 증가시킬 수 있으며 컨텐츠 제작자 측면에서도 유통에 따른 비용을 크게 감소시킬 수 있음을 논하였다. 또한 DRM은 기존의 총량가격 방식 이외에 사용기간 또는 사용 횟수 등 다양한 기준에 따른 가격설정을 가능하게 하며 이를 통해 기업의 이윤과 소비자 총효용 모두 증가할 수 있음을 보였다. 이러한 DRM 기술의 특성은 디지털 컨텐츠 유통의 효율성을 증대시키고 컨텐츠의 질과 다양성 및 가격정책을 통한 사업자들간 차별화를 가능케 하여 산업의 동적인 성장을 가속화 할 수 있을 것으로 생각된다.

  • Purpose - In Korea, general super markets have a great impact on the market performance of traditional markets. We propose a modified two stage DEA model for evaluating the performance of traditional markets in Incheon, Korea by identifying the influence of external environmental factors including the presence of general super markets as non-discretionary variables in DEA. Research design, data, and methodology - After obtaining bias-corrected estimates of original DEA efficiency scores using the input and output data of 49 traditional markets, we regress them on several external environmental factors by bootstrap-truncated regression. Results - We obtain bias-corrected efficiency scores from the original DEA efficiency scores by bootstrap and among the five environmental factors, the residential population and the presence of general super markets or SSMs can be considered as the driving forces influencing bias-corrected efficiency scores, positively and negatively, respectively. Conclusions - When DEA efficiency scores tend to be overestimated, we need to use a biased-corrected efficiency score by bootstrap. It is important to note that the efficiency of traditional markets can be largely influenced by external environmental factors such as the presence of general super markets or SSMs that traditional markets can not control. Therefore, it is desirable to consider such environmental factors appropriately for a reasonable performance evaluation.

  • Purpose - Currently, the distribution environment has been changing rapidly because of the advent of super-supermarkets (SSM),which adopt the "price break" and "lowest price" strategies. Specifically, a diversification of the distribution environment allowed customers to reasonably decide where to shop. With a broadened range of criteria governing the choice of a store, determining changes in the distribution environment should be based on customer satisfaction surrounding the service levels of SSMs. This study examines the effects of service quality and product quality of SSMs on customer satisfaction levels, and analyzes whether these factors affect customers' revisit intention directly. Research design and methodology - A survey method was used and 127 SSM customers responded to the questionnaires that were developed to measure service quality, product quality, customer satisfaction, and store revisit intention. A multi-regression analysis was used to test the hypotheses. Results - Except hypothesis 2, the other seven hypotheses were supported. Hypothesis 2 suggested a positive relationship between product factors and customer satisfaction. Conclusions - This study found a systematic effect of service factors and product factors on customer satisfaction and word-of-mouth, and consequently on store revisit intention.
