Even though there have been greate changes in the types and contents of the housing plan in Korea since the Modem age, it seems that the identity of traditional dwelling culture is still remains within it. The purpose of this study is to examine the characteristics and features in the development of the 'Public Standard' Housing Unit Plan by comparing the differences and similarities in unit plans in housings built on Japanese occupation period and those built after the period. From the study, we can conclude as follows: 1. The public standard housing unit plans on both periods have shown the common features in the composition of their physical forms in the way that the front-row area still remains the traditional housing culture and the rear-row area reflects the desires of the modem lives. The structure of the dual-row unit plan appeared in the public standard housing plan was caused by the cultural acculturation in Japanese occupation period. 2. The public standard housing unit plans, however, show the differences in the contents and meaning in units plans with the them of the Japanese housing because of the cultural differences. These differences took placed autonomously through the change of housing plans in the modern time, and have the common features such that 1) the changes in the Maru-centered plan type differ in composition from the inner-corridor plan type used Japanese housing, and 2) the composition of the open-inner spaces in the double-row housing plan reflects the single-row outer open space In the traditional housing. All of these cultural progresses in the public standard housing unit plans was took place as the result of the inner-oriented and notional circulations derived from the modernity. However, the transformed unit plans still contains the identity derived from the variation of the traditional Korean building elements such as Maru and Ondol. In other words, those are the Maru-centered and composed housing plans with juxtaposition of the inner block and the outer block. As the conclusion, though the public standard dwelling unit plan has the similarity in the physical form, it is different in the cultural Identity and meaning from the public standard plans before the independence from the Japan occupation.

It is a well-known fact that most of the Korean school buildings has been adjusted by the standard plan according to the united and unified teaching method ever since the modern education started. However, seeing the recent growth of care for the open education, the effort to improve the teaching method in school fileds, the practice of the 6th education plan and the education reformation, it can be said that it is high time to change. As the number of schools which practice the open education has been increasing since in 1985 in this atmosphere, there have also appeared elementary schools with the open school building. But the general understanding of the school building and the open space is not enough. Therefore, this study aims to analyze the general spacial conditions, such as the fresh and diverse types of learning method and their development and the concept of the open space along with its types, application, size, and constition by studying, from the standpoint of the building plan, the elimentary schools of a new type in Japan which adopted the open space 20years earlier than in Korean. This study can offer helpful suggestions as to the Korean school building because our situation is very similar to the early stage where the open space is adopted to the school building.

이 연구에서는 우리나라의 모바일 앱 접근성 KS, 미국의 재활법 508조 개정 표준 및 유럽의 BBC 지침을 기준으로 개방형 플랫폼인 안드로이드 모바일 뱅킹 앱의 접근성을 분석하였다. 실험 결과, 우리나라 8개 시중은행의 모바일 뱅킹 앱 중 상기 3가지 표준의 세부 항목을 모두 만족하는 앱은 한 곳도 없었다. 대표적인 위반 항목은 대체 텍스트 미비, 키보드 초점 위반, 컨트롤 크기 및 간격 미준수, 명도대비 비율 낮음 등이었다. 이들 위반사례는 시각장애인, 상지장애인 및 저시력인과 고령자의 접근을 불가능하게 만든다는 점에서 치명적인 오류이다. 모바일 뱅킹 앱이 접근성을 준수하지 않는 원인에 있어서는 모바일 앱 개발자와 제공자들의 접근성에 관한 인식이 낮고 접근성 구현 방법을 제대로 숙지하지 못한 것으로 분석되었다. 우리나라의 모바일 앱 접근성 지침을 재활법 508조 개정 표준 및 BBC 표준과 비교한 결과, 많은 항목이 누락되어 있었다. 또한 평가 기준이 모호하고 추상적이어서 개발자들이 구체적으로 참고하기 어려운 측면이 있는 것으로 판단되었다. 따라서 모바일 앱 접근성 향상을 위한 개발자 및 정부의 노력과 더불어 표준의 보완이 필요하다.

Despite of outstanding optical performance of glass lens, glass lens have not been widely used because of poor productivity and high cost due to manufacturing process i.e. grinding, polishing. However, press-forming method of glass lens overcomes this disadvantage because of mass production. When glass lens is produced by press-forming method using closed die, it is needed that the volume of glass lens preform precisely measured in order to prevent incomplete products and to increase in life of die. The present paper shows the shortcoming of forming process with closed die, and performs FEM simulation of forming process with open die in order to overcome this shortcoming. The design parameter of open die is selected in standard of assembly with optical module and maintenance of optical performance. FEM simulation is carried out with selected parameter of open die and two basic preform. According to distribution of effective strain in glass lens, optical property of glass lens formed at each set of die and preform is compared.

The primary clue for locating protein-coding regions is the open reading frame and the determination of ORFs (Open Reading Frames) is the first step toward the gene prediction, especially for prokaryotes. In this respect, we have developed a web-based ORF search tool called ORF Miner. The ORF Miner is a graphical analysis utility which determines all possible open reading frames of a selectable minimum size in an input sequence. This tool identifies all open reading frames using alternative genetic codes as well as the standard one and reports a list of ORFs with corresponding deduced amino acid sequences. The ORF Miner can be employed for sequence annotation and give a crucial clue to determination of actual protein-coding regions.
