Cultural commodity is a tourism souvenir for tourists with a high added value in terms of economy. When it excellently represents the region and is based upon its tradition, the positive images of the place can be originated. In this way, the formation of benevolent images has economically considerable effects that can promote the competitive power of the area. The purpose of this study is to develop the pattern design of cultural commodity related to Hampyeong Butterfly Festival. The software to be used is Adobe illustrator CS2, which is a Vector Graphic software, and by utilizing the program, the pattern for the cultural goods will be produced. The forms of the pattern are All over Pattern, which is one of the arrangement methods used the most in a necktie field, and Stripe Pattern. After designing with those two patterns, the design is applied on neckties. Like this, by designing through the Vector Graphic software which we can easily get an access to, the concept of design is visualized; therefore, we can prevent the commodity development that can be conducted out of the concept. By making it possible to visualize the examination by various forms or color mixture, the time is shortened, and throughout reproduction of the object, adjustment of the size, colorway, and reusing or remanufacturing the image, we can check the result of design before hand to reduce the time and expenses required.

The development of the Information Technology(IT) has brought enormous change to the human life, not even only to the politics, economy, society, and cultures, but all the way through the people's consciousness and cultural patterns. However, the information society resulted information inequality issues and especially to those disabled people, who have more difficulties on the technology adaptation, the "digital divide" symptom is significantly found. At present the rapid development of IT has gone beyond the level of the information society and it is accelerating the ubiquitous society that will combine people, computers, and all objects into one. And during the time of ubiquitous the "digital divide" will still exist. This research is focused on the digital divide of disabled people that were insufficiently covered in the research of digital divide and ubiquitous. From the empirical study of the effect that the disabled contributes on the service usability in U-City, the factors of background of the digital divide, and the difference of such factors in types of sex, ages, disabled types, and disabled class, and finally how the ubiquitous divide of the disabled affects have been researched. Based on the proposed study model and by analyzing the model by structural equation, following resulted was gained. (1) With the TAM (TAM : Technology Acceptance Model), which is commonly used in the studies of IT devices and services, the digital divide of the disabled cases cannot be identified sufficiently since it is not eligible for Using Intention of U-City Services. (2) In case of the disabled, the mental factors like willingness to overcome the impediment and accessibility like environment to meet the information services and ability to access the services are more effective on Using Intention of U-City Services rather than TAM.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

최대 휘소 투영(MIP) 볼륨 가시화는 의료기기 등에서 생성된 삼차원 영상 데이터로부터 관찰자가 바라보는 방향으로 최대값을 추출하여 영상을 생성하는 가시화 기법이다. MIP는 조영된 혈관 같은 높은 밀도의 구조를 가려짐 없이 드러내어 의료 영상 등에서 많이 사용된다. 본 연구는 두 단계의 가속화 방법을 제안하여 상용 CPU에서 고속으로 MIP를 수행할 수 있도록 한다. 먼저, 기존 MIP 알고리즘이 다수의 조건 분기 명령으로 구성된다는 것에 착안하여, 상용 CPU에서 제공하는 단일 명령 복수 데이터(single instruction multiple data: SIMD) 연산으로 조건 분기 명령을 제거한다. 많은 시간이 소요되는 조건 분기 명령을 제거하여 가시화 속도가 향상된다. 또한 본 연구는 메모리 참조가 순차적으로 발생하도록 알고리즘을 구성한다, 기존 가시화 방법에서 영상과 객체의 메모리 참조가 무작위로 발생하여 발생하던 속도 저하 문제를 완화시킨다. 두 가지 제안 방법을 통해 기존의 쉬어-왑 볼륨 가시화 기법에 비해 7배 이상의 성능 향상을 얻는다.

Information technology will inevitably and profoundly alter every aspect of university life. New information technologies are creating new patterns in the research and teaching, with networks enhancing information sharing and data transmission. The revolution in information technology requires that universities integrate information technology with their traditional missions of teaching, research, and public service. Enhanced mode of information access and changing information-seeking behaviors suggest the need for new library services. New technologies have opened up many new services options for libraries. The nature of and potential for new information services suggest that libraries should become better connected with other campus units. Some of these issues will no doubt be addressed by the a n.0, pplication of new technologies and by building campus information infrastructure. An important element of the needed change for enhancing the library information services is the integration of the libraries and computing centers. Libraries and computing centers deal with the same commodity-information and delivering information. For the sake of scholarship and research, the two must devise an integrated a n.0, pproach to delivering the common commodity. Computing centers have special skills in system development and telecommunications. Libraries have good human interface skills and skills for organizing knowledge. Together they could be a particularly productive team. Noting this, some universities have created new information service units which unify the present-day computing, library and telecommunication functions. Existing models range from true merging to situations where some cooperative activities are being conducted. The purpose of this study is to suggest the direction in developing of information services in academic libraries by examining the changing information environment and trends of integrating libraries and computing centers. This paper inquires into the changing information environment, the impact of imformation technology on universities and libraries, some casses of integration of academic libraries and computing centers, and effects of integration of two and suggests the developing direction of information services in academic libraries.
