In this work, nano-needle structures ate formed to solve problem, related to low density of quantum dots for nano floating gate memory. Such structures ate fabricated and electrical properties' of MIS devices fabricated on the nano-structures are studied. Nano floating gate memory based on quantum dot technologies Is a promising candidate for future non-volatile memory devices. Nano-structure is fabricated by reactive ion etching using $SF_6$ and $O_2$ gases in parallel RF plasma reactor. Surface morphology was investigated after etching using scanning electron microscopy Uniform and packed deep nano-needle structure is established under optimized condition. Photoluminescence and capacitance-voltage characteristics were measured in $Al/SiO_2/Si$ with nano-needle structure of silicon. we have demonstrated that the nano-needle structure can be applicable to non-volatile memory device with increased charge storage capacity over planar structures.

This study reviews the process of creating the patterns through the Christopher Alexander’s books to discover the fundamental rules for creation of the pattern language. The essential ideas of 11 rules describing the characteristics of the pattern language are organized by keyword depending on the characteristics of each rule. Then, this study analyzes which keyword was applied importantly and how it had been developed chronologically in the Alexander’s books. As a result, 5 keywords — reflection of cultural difference, reflection of human desires, solving the repeated problem, function suitable for principal purpose, and network structure — are applied to his early books in which the pattern language was theoretically developed, the pattern of traditional society was discovered and the network structure was developed. Another 5 keywords — user participation method, new problem solving, structure preserving transformation, post-mechanization method, and central invariant structure —are applied to the books in his mid-term after completion of the pattern theory which discover new pattern for contemporary society and apply the pattern language to time and space. In his later books which organize the theory of pattern language and suggest the direction for using the pattern language, 5 keywords — wholeness, post-mechanization method, user participation method, new problem solving, and structure preserving transformation — are applied. Users may use the pattern language more precisely if he/she considers the keywords of the early period in searching the patterns of existing environment, the keywords of the intermediate period in searching the patterns of new environment or in regard to time and space, and the keywords of the later period in considering direction of the application of the pattern language.

To complete the appropriate pattern language as a planning tool for suburban houses in Korea, this study reviews the characteristics in applying the pattern language to suburban houses in Korea by creating the pattern application examination chart regarding 110 patterns in architecture and evaluating and analyzing 24 examples in terms of the applicability of the patterns, the results of which are as set forth below. Firstly, when grouping the upper 31 patterns by similar characteristics, it was distinguished by the characteristics relating to (i) securing of lighting and viewing; (ii) placing of buildings and space and adjustment of inside and outside privacy through such placing; (iii) placing of proper motion line and functions of adjacent space according to such motion line; and (iv) determining of important space such as personal room, area for couple or children, staircase, entrance, hallway, etc. Secondly, when analyzing the reasons that the lower 41 patterns have not been applied, it was characterized by (i) the work space not suitable for suburban houses or the patterns suitable for commercial space; (ii) the patterns not suitable in Korea due to cultural differences; and (iii) the patterns whose applicability cannot be confirmed due to the limitation of examples and materials used in this study. Thirdly, the analysis of each pattern group (A through M) revealed that the pattern groups D and G are rarely related to suburban houses and J and M are patterns whose applicability cannot be determined in this study. Another characteristics is that the pattern groups B, E, F, I and L which obtain high scores in applicability are importantly reflected in planning for suburban houses in Korea. Fourthly, this study renders the average score of applicability, and the applicability rate, of the examples and confirms the number of the patterns applied in confirmity, patterns partially or potentially applied and patterns not applied at all.

In recent years, service delivery systems employing a self-service approach have been rapidly spreading. Since a self-service system provides a lower product price, it attracts more customers. However, some system managers are still hesitant to accept a self-service system, because there is no systematic model to predict its performance. Therefore, this research attempts to provide a systematic and quantitative model to predict the performance of a self-service system, focused specifically on a self-service gas station. Under this model, the traditional queuing theory was adopted to describe the general self-service process, but it is also assumed that some changes occur in both the customer arrival rate and the service performance rate. In particular, the price elasticity was introduced to capture the change in the customer arrival rate, and the existence of learning effect and helpers were assumed to design the changed service performance rate. Under these assumptions, a simulation model for a self-service gas station is established, and three performance measurements, such as average number of customers, average waiting time, and Utilization are observed, depending on the changes in price difference and helper-operating time. In this research, the optimal operation strategy for price differentiation and helper-operating time is proposed in accordance with the level of the customer learning rate. Although this research confines the scope of the study to the self-service gas station model, the results of this research can be applied to any type of self-service system.

『금강경』의 표현방식에 관한 연구

정성욱(Jung, Sung-wook) 불교학연구회 2013 불교학연구 Vol.36 No.-

현대 한국불교의 사상은 『金剛經』을 중심으로 하고 있다고 해도 과언이 아니겠지만,불교역사에 있어서도 수많은 판본과 주석서가 그 중요성을 말해준다. 그러나 수많은 주석서들은 지나치게 현학적으로 기술되어 있거나 格外道理를 강조하다 보니 본문의 흐름이나 표현방식을 간과하고 있다. 이에 본고는 『금강경』 본문의 표현방식의 변화를 살피면서 본문을 좀 더 명확하게 분석하고자 하였다. 여기서는 구마라습역을 중심으로 하고 전재성과 각묵역을 참조하여 본문 분석의 기초를 삼았다. 그리고 『금강경』을 한역하면서 상하로 구분하거나 두 부분으로 구분한 학자들도 있지만 구분의 필연성보다 편의적 기준으로 나누어져 있었다. 그래서 본고는 卽非的 話法과 卽非是名的 話法을 분류의 기준으로 삼아 『금강경 』 본문을 두 부분으로 나누어 보았더니 전반부는 주로 즉비적 화법으로 표현되어 있었고 후반부는 즉비시명적 화법으로 이루어져 있음을 발견하였다. 이에 본고는 즉비적 화법과 즉비시명적 화법의 차이점을 분석하여 보임으로써 『금강경』후반부의 표현방식이 전반부의 표현방식과 배치되는 입장에 있다는 결론에 도달하였다. It is commonly recognized that contemporary Korean Buddhist thought is largely based on the Diamond Sutra [金剛經]. A considerable number of printings and commentaries attest to the importance of the Diamond Sutra in the history of Buddhism. However, many such commentaries are often written in a pedantic manner and ignore the original text's flow or mode of expression, by emphasizing supramundane principles outside the realm of ordinary conceptual thought [格外道理]. Therefore, this study attempts to analyze the Diamond Sutra [金剛經] more clearly by examining the changes in its mode of expression. In this essay, the analysis of the original text is mostly based on the commentary of Kumārajīva (鳩摩羅什: 344-413), with references to Jae-Seong Cheon's (金在星:2003) and Gakmuk's (覺黙:2001) translation. Though some scholars divided the Diamond Sutra [金剛經] into two parts when translating into Chinese, this was not due to inevitability but due to convenience. Therefore, this study attempts to divide the Sutra into two parts, classifying it as ‘Just-not Speech’ [卽非的 話法] and ‘Just-not but-named Speech’ [卽非是名的 話法]. I find that the former was mostly composed of ‘Just-not Speech’ [卽非的 話法] and the latter ‘Just-not but-named Speech’ [卽非是名的 話法]. Through the analysis of the difference between the two, this essay concludes that the Sutra's mode of expression in the two parts conflict with each other.
