최근 환경오염과 생태학적 환경문제가 사회적 중요한 관심사로 인식되고 있다. 포장디자인에 있어서도 재활용과 재사용에 대한 요구와 함께 스티로폼이나 플라스틱을 대체하는 친환경 포장용기와 생분해성 필름 등의 포장재의 개발과 생산이 점차 증가하고 있다. 이러한 사회적 배경에서 본 연구에서는 환경친화적 포장디자인의 개발을 위한 가이드라인 설정을 목적으로 하고 있다. 연구내용은 환경친화적 디자인의 개념과 에코 포장디자인 적용범주, 국내외 에코패키지의 동향 및 포장재 현황을 살펴보고, 각종 정책과 규정 및 관련지침 등의 이론적 자료들을 근거로 일반적으로 고려되고 있는 에코패키지의 기본 방향과 체크리스트를 분석하였으며 이에 따른 가이드 라인 및 수행 절차를 고찰하였다. 에코 패키지의 기본방향은 첫째, 포장디자인의 제작, 사용, 폐기에 이르는 전과정에서 환경측면을 고려해야 하며 둘째, 비용과 품질, 시장성, 디자인 등 다중요소를 고려해야 한다. 셋째, 디자인 부서와 제품설계부서, 생산부서, 환경팀 등 조직 내의 다른 시스템과 기능적으로 협력하여야 하며 넷째, 기업의 다른 여러 가지 환경 활동을 통해 잠재적인 소비자와 시장을 확대할 수 있다는 것이다. 가이드라인의 내용은 자원 절감과 물질 사용량 절감, 재활용성 확대, 에너지 효율 향상, 유해 물질 저감과 안전성 확보, 폐기 효율성을 중심으로 하고 있다. 환경 친화적 포장디자인의 실천을 통해 환경영향성을 개선하고 비용을 감소시키며 소비자의 이미지 개선에도 기여할 것으로 기대된다.

The user interface design needs to support the complex interactions between human and computers. It also requires comprehensive knowledges many areas to collect customer's requirements and negotiate with them. The user interface designer needs to be a graphic expert, requirement analyst, system designer, programmer, technical expert, social activity scientist, and so on. Therefore, it is necessary to research on an designing methodology of user interface for satisfying various expertise areas. In the paper, We propose the 4 business event's abstract object visualizing phases such as fold abstract object modeling, task abstract object modeling, transaction abstract object modeling, and form abstract object modeling. As a result, this modeling method allows us to enhance visual cohesion of UI, and help unskilled designer to can develope the higy-qualified user interface.

핸드폰에 의한 모바일 콘텐츠의 사용량이 날로 증가하고 있으며 이러한 추세에 맞추어 다양한 콘텐츠들이 다양한 플렛폼에서 생산되고 있다. 모바일 플랫폼에서 사용 가능한 콘텐츠 생산성은 플랫폼의 특수성으로 인해 생산 속도가 느리고 인력 투입이 많은 것이 문제점으로 지적되고 있다. 또한 무선 플랫폼에서 사용 가능한 콘텐츠 제작시 다양한 하드웨어 플랫폼으로 인한 액정 크기의 다양성과 사용 가능한 콘텐츠 개발 언어의 다양성으로 인한 문제점도 많은 것으로 알려져 있다. 본 연구에서는 이러한 생산성 저하의 원인으로 대표되는 문제점들과 다양한 하드웨어 플랫폼으로 인해 발생하는 문제점들을 해결하기 위한 모바일 콘텐츠를 통합 제작하고 테스트하는 PC용 소프트웨어를 개발하였다. xHTML 언어로 제작된 모바일 콘텐츠를 다양한 언어로 변환하기 위하여 패턴매칭 알고리즘을 사용한 변환 모듈을 개발하였다. 또한, 변환된 콘텐츠들을 각 플랫폼별로 테스팅 하기 위하여 개발자의 직접적 개입이 없이 모든 콘텐츠를 자동으로 검사하고 결과를 리포트 생성하는 자동 테스트 부분과 개발자의 육안으로 확인하고 테스트하여 결과 리포트를 생성하는 수동 테스트 부분으로 나누어진 소프트웨어 엔진을 개발하였다. 이상의 변환엔진을 사용하여 xHTML로 제작한 원본 콘텐츠는 다양한 플랫폼에서 이용 가능한 콘텐츠로 생산이 용이해 졌으며, 두 테스트 엔진을 사용하여 기본적인 콘텐츠 오류들을 쉽게 찾아내고 수정할 수 있는 개발 환경을 구축하였다.

According to rapid growth of web environment, user interface design needs to support the complex interactions between human and computer. In the paper we suggest the object modeling method for Qualify Improvement of User Interface. We propose the 4 business event's object modeling phases such as business event object modeling, task object modeling, transaction object modeling, and form object modeling to enhance visual cohesion of UI. As a result, this 4 phases in this paper allows us to enhance visual cohesion of User Interface prototype. We have found that the visual cohesion of business events become strong and unskilled designer can develope the qualified user interface prototype. And it also improves understanding of business task and reduces prototype system development iteration.

This paper describes difficulties for the producer's distribution and the user's acquisition of the spatial data because the circulation of them is complicated according to its kind in Korea. The way to overcome these difficulties would be to develop the clearing house system to incorporate GIS technology on Internet. This research proposes the problem statement, the architecture, and the operating environment of the system. The system contains the functions such as metadata generation, metadata registration, metadata version management, catalogue creation and update, reports generation, forms processing, metadata search, payments, GIS information pool, and spatial data browsing.

Two-step water splitting thermochemical cycle with $CeO_2$ foam device was investigated by using a solar simulator composed of 2.5 kW Xe-Arc lamp and mirror reflector. The hydrogen production of $CeO_2$ foam device depending on reaction temperature of Thermal-Reduction step and Water-Decomposition step was analyzed, and the hydrogen production of $CeO_2$ and $NiFe_2O_4/ZrO_2$ foam devices was compared. As a result, the amount of reduced $CeO_2$ considerably varies according to the reaction temperature of Thermal-Reduction step. and hydrogen production was not much when the amount of reduced $CeO_2$ decreased even if the reaction temperature of Water-Decomposition step was high. Therefore, it is very important to keep the reaction temperature of Thermal-Reduction step high in two-step thermochemical cycle with $CeO_2$.

As a means of overcoming the linguistic barrier between different languages in the Internet cyberspace, a sign-language communication system has been proposed. However, the system supports avatars having the same model structure so that it is difficult to communicate between different avatar models. Therefore, in this paper, we propose a new gesture communication system in which different avatars models can communicate with each other by using a FBML (Facial Body Markup Language). Using the FBML, we define a standard document format that contains the messages to be transferred between models, where the document includes the action units of facial expression and the joint angles of gesture animation. The proposed system is implemented with Visual C++ and Open Inventor on Windows platforms. The experimental results demonstrate a possibility that the method could be used as an efficient means to overcome the linguistic problem.

In the present study, dominant factors for temperature increase and effects of mass entering the resonance tube of the gas-dynamic igniter are investigated. Using RhoCentralFoam solver in OpenFOAM program, numerical simulation is performed for three different cases. In the results, the heating of the working fluid is found to be a result from aero-thermodynamic phenomena. Appropriate mass entering to the resonance tube is found to be an important dominant factor as well.

This research examines the characteristics of the "rammed earth form" based on the criteria for the selection of forms. For this purpose, the paper first reviews the characteristics and orientation of the earth-construction and looks into the outline, the prerequisite, the current status and the tendency of the rammed earth form system through previous studies. Consequently, we aims to contribute to the criteria for the selection of rammed earth forms in the future through a comparative analysis of the construction cost, quality, safety and easiness of works between the veneer board form and the euroform, which are most widely used at earth housing project in the domestic country. The results reveals that the euroform is better than the veneer board with 21% of total cost in the cost analysis. But this better than that in the side of easiness of construction. In both cases, the buckling of wall panel form and the labor-oriented characteristics of the methods are the future research issues in the rammed earth form system.
