웹페이지 코드 분리를 위한 리마커블 처리기의 설계 및 구현

강동현 ( Dong-hyeon Kang ),이관용 ( Kwan-yong Lee ) 한국정보처리학회 2007 한국정보처리학회 학술대회논문집 Vol.14 No.1

웹프로그래밍 환경에서 프리젠테이션 로직을 구성하는 서버처리 웹페이지에는 디자인을 위한 HTML 요소와 로직을 구현하기 위한 서버측, 클라이언트측 스크립팅 요소가 혼합되어 있다. 이와 같은 경우 스파게티 코딩에 의해 웹디자이너와 웹프로그래머간의 작업의 경계가 불분명해지고 디자인과 로직의 구성이 정렬되지 못하는 문제점이 발생할 수 있다. 본 논문에서는 이러한 문제점을 해결하고 웹페이지의 가독성과 재사용성을 향상시키기 위한 리마커블 코드 분리 모델을 제안한다. 이를 통해 웹페이지 수준에서 HTML 요소와 스크립팅 요소를 완전하게 분리하고 관련 연구와 차별화되는 플랫폼 독립적이고 언어 중립적인 웹페이지 모듈화 과정을 소개하고자 한다.

The objective of this paper is to design multichannel spherical loudspeaker array by considering various positioning methods such as Gaussian grid, Lebedev grid and packing method. For the spatial sound manipulation, which is to make desired sound field by controling multiple sound sources, the Kirchhoff-Helmholtz integral states that sound fields can be reproduced in terms of infinite control sources on the integral surface. But since we cannot control infinite number of sources for the implementation, we have to allocate finite number of sound sources which can approximately act as infinite number of sources. To manipulate sound field inside of a sphere (which is typical example of three dimensional array) by controlling sound sources on the surface, three methods of allocating sound sources, which are Gaussian grid, Lebedev grid and packing method, are reviewed. For each geometry, the performances of manipulation rendered by time-reversal operator and higher-order ambisonics are compared.

A tort is not always composed of by the act of only one man but may be made up of by the act of several persons, which is called $quot;cotort$quot; and is prescribed in Article 760 of the Civil Code. Here in this provision are included three kinds of types. In this study, through the survey of the judicial precedents of two countries Korea and Japan, and by the reconsideration and the comparison of the contentions of theories, the development of the concept of the cotort has been made .an attempt centering around Article 760 of the Civil Code. As a result, the conclusions acquired from several important points at issue are as follows: A) It is considered that joint cognition-subjective joint one-is required as the requisite for organizing the cotort in a narrow sense. As compared with ther differences between Paragraph Ⅰ & Ⅱ of this Article, the way of the above-mentioned interpretation of this Article is found to be reasonable, and it is based on the consideration that the cotort cannot be consisted of between an intentional person and a negligent one. B) The joint liability imposed on the doer of the cotort is regarded not as unreal joint debt but as real joint one. It is because Article 760 of the Civil Code must be esteemed according to the context of it, and because the substantial balance among the debtors has to be kept. C) In our Civil Code, the distinction between the cotort in a narrow sense and the cotort done by unknown injurer is interpreted in a different way from the former Japanese Civil Code and the majority of theories. The establishment of the cotort corresponds to Paragraph Ⅰ of the Article 760 exclusively in case the doers have the subjective joint correlation, and in case the act has the objective joint correlation only, Paragraph Ⅱ. D) In case there is a cotort done by unknown injurers, it seems that, one of them who demonstrated that his act did not result in the damage, should be free from the joint debt.

삼중화된 회로에서의 결함 감지를 위한 방법에 관한 연구

SRAM-based FPGAs are very sensitive to single event upset(SEU) induced by space irradiation. To mitigate SEU effects, space applications employ some mitigation schemes. The triple modular redundancy(TMR) is a well-known mitigation scheme. It uses one or three voters as well as three identical blocks performing the same work. The voters can mask out one error in the outputs from the three replicated blocks. One SEU error in TMRed circuits can be masked but it needs to be detected for some reasons such as to analyze the SEU effects in the satellite or to recover the circuits from the error before additional error occur. In this paper, we developed a fault detection circuit and reporting system to detect a fault on the TMRed circuits. To verify our error detection circuit and reporting circuit, we performed an irradiation test at MC-50 Cyclotron. Experimental results showed that error detection circuit can detect a fault on the TMRed test circuit in radiation environment.

In this study, a new wet etching method and the solution for thinning the glass with the thickness below 100 μm were investigated. For the preparation of etching solution with low hydrofluoric acid, it was effective to use NH(4)HF(2) as a main ingredient with addition of sulfuric acid. Flexibility of the etched glass was greatly improved at below 100 μm thickness. To confirm the possibility as flexible display substrate, the ultra thin grass with 50 μm thickness was coated with ITO (Indium Tin Oxide) transparent electrode and its electrical conductivity was investigated.

본 연구에서는 RTO(Regional Tourism Organization) 조직목표의 성공적 달성과 조직이 나아갈 방향을 제시하고자 RTO의 구성원들을 대상으로 조직구조, 조직문화, 개인역량 요인에 대한 영향관계를 분석하였다. 실증분석을 위해 RTO운영형태에 따라 서울관광재단, 전라북도문화관광재단, 경기관광공사, 인천관광공사의 조직구성원들을 대상으로 설문조사를 실시하였는데 그 분석결과는 다음과 같다. 첫째, 조직구조가 조직문화에 미치는 영향관계를 분석한 결과, 조직문화의 하위요인인 집단문화의 경우 공식화요인, 발전문화는 공식화, 집권화 요인, 위계문화는 공식화 요인, 마지막으로 합리문화에 대해서는 공식화, 집권화 요인이 각각 유의한 영향을 미치는 것으로 나타났다. 종합하면, 공식화는 모든 조직문화 하위요인에 대해 정(+)의 영향을 미치는 반면, 복잡화는 모든 하위요인에 영향을 미치지 않는 것으로 나타났다. 둘째, 조직문화가 개인역량에 미치는 영향관계를 분석한 결과 첫째, 개인역량 하위요인 중 상황분석능력에 대해서는 합리문화, 발전문화, 위계문화가, 대인관리능력에 대해서는 합리문화, 위계문화가 유의한 영향을 미치며, 업무능력에 대해서는 발전문화, 위계문화가 통계적으로 영향을 미치는 것으로 분석되었다. 분석된 내용을 바탕으로 다음의 시사점이 도출되었다. 첫째, 공사의 경우는 수익성에 대한 다양한 아이디어 보상제도 운영과 조직 내 수익성 추구 전담부서 설립 등을 통해 구조화, 규칙화 시키는 과정이 필요하며 수익성 및 개인역량 향상에 대한 조직 내 정확한 목표치를 제시하여야 한다. 둘째, 이러한 목표를 중앙 및 해당지자체 내·외부, CEO 평가목표에 반영하여야 한다. 재단의 경우는 지역적으로 관광과 연계한 사회문제 해결 등을 목표화하여 목표달성에 큰 역할을 한 팀 또는 개인에 대해 인센티브제도 등을 규정화, 공식화 하는 작업이 필요하다. This study analyzes the impact of organizational structure, organizational culture, and personal competence tors on members of the Regional Tourism Organization (RTO), a leading enforcement organization of local tourism policies, to successfully achieve RTO organizational goals and directions, the Seoul Tourism organization, Jeollabuk-do Cultural Tourism Foundation, Gyeonggi Tourism Organization, and Incheon Tourism Organization were surveyed according to the type of RTO operation, and the results of the analysis were as follows. First, the analysis of the impact of organizational structure on organizational culture showed that formalization factors on group culture, formalization and centralization factors on developmental culture, formalization factors on hierarchical culture, formalization and centralization factors on rational culture, formalization has also been shown to have a positive influence on all organizational culture sub-factors. Second, as a result of analyzing the impact of organizational culture on personal competence, it showed that the ability to analyze situations among the sub-factors of personal competence was significantly influenced by rational culture, developmental culture, hierarchical culture, rational and hierarchical culture have a statistical impact on interpersonal management ability, developmental culture, hierarchical culture statistically influences the work ability. Based on these results, strategies by type of organization's operation require a process of structuring and regularizing various idea compensation schemes for profitability and establishment of a dedicated department for profitability in the organization, and an accurate target for profitability and individual capacity improvement. In addition, these objectives should be reflected in the central and internal, external, and CEO evaluation objectives of the relevant local government. In the case of the foundation, it is necessary to define and formulate an incentive system for teams or individuals who have played a major role in achieving their goals by targeting social problems linked to tourism locally.
