The purpose of this study was, as an experimental one, to suggest concrete ways to use computer in fashion design from information collection to design completion, and to present a real example based on the suggested ways. The first step to attain the purpose was gathering various sorts of worldwide fashion design information on the Internet, and then the collected data were inserted in a graphic file. Next, two methods of fashion design that use computer graphics were recommended : one was to produce fashion design just by altering some of the inputted Internet fashion materials, and the other was to do it after selected basic materials were put in database. Those methods could enable one to do fashion design just with rearrangement and smallest change of the prepared basic materials, without drawing directly, and at the same time, they could minimize time and efforts required for computer fashion design.

The advent of Wireless Sensor Networks (WSN) has led to their use in numerous applications. Sensors are autonomous in nature and are constrained by limited resources. Designing an autonomous topology with criteria for economic and energy conservation is considered a major goal in WSN. The proposed honey-hive clustering consumes minimum energy and resources with minimal transmission delay compared to the existing approaches. The honey-hive approach consists of two phases. The first phase is an Intra-Cluster Min-Max Discrepancy (ICMMD) analysis, which is based on the local honey-hive data gathering technique and the second phase is Inter-Cluster Frequency Matching (ICFM), which is based on the global optimal data aggregation. The proposed data aggregation mechanism increases the optimal connectivity range of the sensor node to a considerable degree for inter-cluster and intra-cluster coverage with an improved optimal energy conservation.

디자인 개발시 사용자 참여의 중요성이 날로 증가하고 해지고 있는 램에서의 사용성 평가는 여러 가지 면에서 극히 제한적이며 비용이 많이 들고 시간 또한 많이 소비된다. 또한 이러있는 것은 자명한 사실이다. 그중 사용성 평가에서의 사용자 참여는 비교적 활발한 상태이다. 하지만, 현재 기본적으로 행한 평가는 광범위한 정보의 수집과 빠른 피드백을 얻는데 여러 가지 문제점을 가지고 있다. 본 연구에서는 이상과 길은 배경을 바탕으로 실험실에서의 사용성 평가에서 생기게되는 여러 가지 요인 등에 의해 제한되었던 사용자들의 참여를 극대화하기 위하여 초기 디자인 프로토타입을 웹상에서의 사용성 평가 정보 취합 도구로 활용하는 방안을 모색하였다.

A conventional passive TMD is only effective when it is tuned properly. In many practical applications, inevitable off-tuning of a TMD occurs because the mass in a building floor could change by moving furnishings, people gathering, etc. When TMDs are off tuned, TMDs their effectiveness is sharply reduced. This paper discusses the application of MR-TMD, semi-active damper, for the reduction of floor vibrations due to machine and human movements. Here, the groundhook and skyhook algorithm are applied to a single degree of freedom system representative of building floors. And displacement and velocity base control method are applied to reduce t100r vibration. The performance of the STMD is compared to that of the equivalent passive TMD. Comparison of the results demonstrates the efficiency and robustness of STMD with respect to equivalent TMD.

With the development of Chinese petroleum and gas industry, about 20,000 km long-distance pipeline and 250,000 km gathering pipeline have been constructed in China. After operating for many years, most of the coatings on buried pipelines have aged so severe that the steel pipes are subject to corrosion environment underground. Focusing on the need of external coating for buried pipeline rehabilitation, a new type of coating has been developed. The development and application of the coatings has been introduced in this paper.

1. Objectives The purpose of this study is to find the ground why constitution must be classified into 4 types. 2. Methods I analysed the basic presuppositions to class 4 Type Constitution in Sasang Constitutional Medicine(SCM). And I connected the presuppositions with other theories from the viewpoint of directional properties of human body. 3. Results and Conclusions The most important presupposition to class 4 Type Constitution and apply to clinical therapy in SCM is that there is native strength and weakness of lung's Exhale Dispersing Qi, liver's Inhale Gathering Qi, spleen's Ascending Yin Qi and kidney's Descending Yang Qi. If there is superior tendency of Qi flow direction in human body, 6 directions(upward, downward, forward, backward, outward and inward) will be remarkable. But, in embryonic period, the outer skin is originated from the back(ectoderm) and the alimentary canal is from the front(endoderm). Therefore 4 directions(upward, downward, outward and inward) will be more remarkable, and those directions are included in the former presupposition.

Corporate sectors and individuals are in need of valuable and relevant information to swiftly adapt to the Internet-driven business or educational environment. This research employs the intelligent survey agent and online application form to help people to locate the information they would want from internet quickly. Based on Internet GUI environment, this user-friendly outline survey and outline application form program uses the agent concept to provide the customized, individual information to the users who registered their survey answers, to the extent of increasing the interest and participation of users. The system helps along with the decision making process, by quickening the information gathering process.

Wireless sensor networks(WSN) technology has various applications such as surveillance and information gathering in the uncontrollable area of human. One of major issues in WSN is the research for reducing the energy consumption and reliability of data. A system with forward error correction(FEC) can provide an objective reliability while using less transmission power than a system without FEC. In this paper, we propose to use LDPC codes of various code rate(0.53, 0.81, 0.91) for FEC for WSN. Also, we considered node-to-node interference in addition to AWGN channel. The proposed system has not only high reliable data transmission at low SNR, but also reduced transmission power usage.

Ultrafine powders(UFPs) of aluminum nitride(AlN) have been synthesized by chemical reactions in the nitrogen atmosphere and the gaseous aluminum evaporated from Al powders in thermal plasmas produced by a DC plasma torch. A synthesis system consisting of a plasma torch, a finely-controllable powder feeder, a reaction chamber, and a quenching-collection chamber have been designed and manufactured, and a filter for gathering AlN UFPs produced by the quenching process subsequent to the synthesis is set up. The synthesis process is interpreted by numerical analyses of the plasma-particle interaction and the chemical equilibrium state, respectively, and a fully-saturated fractional factorial test is used to find the optimum process conditions. The degrees and ultrafineness of synthesis are evaluated by means of SEM, TEM, XRD, and ESCA analyses. AlN UFPs synthesized in the optimum process conditions have polygonal shapes of the size of 5-100 nm, and their purities differ depending on collecting positions and filter types, and the maximum purity obtained is 72 wt% at the filter.

In the evaluation of rural amenities, its properties are related with social, cultural, and environmental elements. In this study, Information Measure Model (IMM) and Cultural Property Priority Assessment Model (CPPAM) were developed adapting information measure model with text based surveying data. To apply developed model not only general properties but also specific surveyed data, Specific Information Gathering and Utilizing System (SIGUS) was constructed using the data in Dusan World encyclopedia. IMM shows priorities of cultural property by information in national-designated cultural properties. And CPPAM applied in surveying data in 2004 by Rural Resources Development Institute.
