In order to contribute to trial of the ocean weather forecasts, we have developed new generation sea surface temperature. It is clod free, high-spatial resolution daily SST product, which enables us to follow the movements of SST patterns relating to the oceanic variations. The product is produced through an objective analysis merging various infrared and microwave SST products.

NOAA operational bulk SST product (Reynolds et al, 2002) is very popular global SST data sets and is extensively used for various studies. However, the original time resolution is weekly and relatively large. On the other hand, there exist many new global SST data sets at present. In this study, we compare many global SST data sets including NOAA operational bulk SST product, CAOS OI SST product, Microwave Optimum Interpolation (MWOI) SST, Real Time Global (RTG) SST and JMA merged satellite and in situ Global Daily (MGD) SST.

품질보증데이터는 제품의 신뢰성평가에 귀중한 자료이므로 기업에서는 이를 분석하여 제품의 개선전략을 세운다. 하지만 기업에서는 제품의 수명을 고려하지 않고 통상 월별 또는 분기별 클레임건수를 1000제품 당으로 나타낸 품질보증회수율을 구하여 표나 그림으로 나타낸다. 본 연구에서는 그런 데이터를 통상적으로 어떻게 분석하는지 살펴보고 수명까지 고려한 분석이 효과적임을 설명한다. 아울러 이런 분석의 결과는 신뢰성추적시스템에 들어가야 됨을 설명한다.

In order to promptly cope with the various requirements of consumers, the environment of product development is being globalized in manufacturing industrials. For this reason, it is necessary to build up an efficient collaborative system for communication between remote area designers. Specially, while Internet and information technologies were merged with the manufacturing or business process, the research for collaborative system has become an important issue. Therefore, we propose a Web-based Engineering Collaboration Framework using SPS(SharePoint Portal Server) which is an enterprise business solution that integrates information from various system into one solution through single sign-on and enterprise application integration capabilities, with flexible deployment options and management tool. Through a Web-based Engineering Collaboration Framework, designers can share knowledge assets and have a remote conference with others via web.

의료와 관련하여 디자인은 대표적으로 시각디자인(Visual Communication Design), 제품디자인(Product Design) 그리고 환경디자인(Environment Design)이 의료 환경을 미적으로 아름답고 편리하도록 지원하는 형태로 관계를 형성하고 발달해왔다. 그러나 근래 디자인에 있어서 전문성이 증대되고, 다양한 영역과 학문과 융합하여 세분화되고 전문화된 영역이 새롭게 생성되고 있다. 더불어 디자인은 기술의 발달로 인하여 다양한 산업, 학문, 서비스와 융합하여 새로운 형태의 모델을 만들며 끝임 없이 변화하고 있는 상황이다. 이러한 디자인의 변화와 발달의 상황을 인식하고 의료 서비스에 있어서 디자인 활용에 대한 연구를 진행하여, 전통적인 디자인의 영역에 한정적으로 활용되던 디자인에서 벗어나 새로운 가치를 창출할 수 있는 의료 서비스 디자인으로 발전해 나가는 연구를 제안한다.

Recent three-dimensional feature-based CAD systems based on solid or non-manifold modelling functionality have been widely used for product design in manufacturing companies. When product models associated with features are used in various downstream applications such as analysis, however, simplified and abstracted models at various levels of detail (LODs) are frequently more desirable and useful than the full detailed model. To provide multi-resolution models, the features need to be rearranged according to a criterion that measures the significance of the feature. However, if the features are rearranged, the resulting shape is possibly different from the original because union and subtraction Boolean operations are not commutative. To solve this problem, in this paper, the new concept of the effective zone of a feature is defined and identified using Boolean algebra. By introducing the effective zone, an arbitrary rearrangement of features becomes possible and arbitrary LOD criteria may be selected to suit various applications. Besides, because the effective zone of a feature is independent of the data structure of the model, the multi-resolution modelling algorithm based on the effective zone can be implemented on any 3D CAD system based on conventional solid representations as well as non-manifold topological (NMT) representations.

Conceptual database design is an important activity because the performance of a DBMS heavily depends on the proper design of the database, and view integration is one of the most important phases of conceptual database design. During this phase, the individual views designed by separate user groups are integrated into a global view for the entire system. After the view integration, a database schema must be validated before it becomes a stable product of the design. In this paper, a methodology for view integration an validation is suggested. The individual views are modeled by entity-relationship model. The entities are integrated according to their name and domain information. After that, the relationships are merged by their constraints. We also present a methodology for checking redundant relationships which has an algorithmic description.

A new adder-and-accumulator (A$^2$C) adapted to pipelined Δ$\Sigma$ modulators is proposed in this paper. With the viewpoint of area consumption, registers are removed in the existing pipelined Δ$\Sigma$ modulator, and then adder and accumulator are merged. In order to optimize area consumption, speed and power consumption, dynamic carry look-ahead adder (CLA) is adopted in $A^2$C. Moreover, a guideline for the transistor sizing in CLA with regard to the minimization of the energy-delay-area product (EDAP) is proposed[1]. The proposed $A^2$C has been verified by HSPICE simulations.

This study provides the structural design for commercialization of outdoor breathable waterproof jackets for men merged with solar cells to enable emergency communications, utilizing wearable devices to develop smart clothing and extend convenience in everyday life. The most popular waterproof jacket with two-layer and three-layer moisture-permeable waterproof fabric was selected, based on previous studies of functional outdoor jackets and style with affinity to fashion. Flexible solar films suitable for clothing were embedded in the lining of the sleeve area and hood visor, and printed film was developed to balance weight and design. High performance smart solar jackets have application to expanding the use of smart phones for everyday and emergency communication, and leisure and outdoor sports activities, as well as day-to-day functions as a waterproof breathable outdoor jacket for men. It is also eco-friendly. Satisfying both the aesthetic and practical, a solar cell jacket with smart features, is an innovative tool for use in a variety of outdoor activities, and a fashion-forward commercialized product.
