국민생활수준 향상에 따라 식품소비패턴이 변화되고 소비자의 안전 농식품에 대한 요구도 증대하고 있다. 2005년 12월 국무조정실에서 실시한 설문조사에 따르면 식품구입 시 가장 우선적으로 고려하는 요소로 응답자의 약 34%가 '위생안전'을 꼽았다. 이는 유통기한을 선택한 36%까지 합하면 무려 70%가량이 안전성을 가장 우선적으로 생각한다는 결과이다. 최근 미국산 쇠고기 수입재개와 관련하여 나타난 식품안전에 대한 국민들의 관심과 수준은 단순히 통계수치와는 비교도 할 수 없는 거대한 전율을 느끼게 만들기에 충분한 것이었다. 식품안전에 대해 이렇게 수준 높은 소비자들의 욕구를 모두 만족시킬 수있는 정책을 단기간에 개발하기란 쉽지 않겠지만 한편으로는 올바른 정보들이 충분히 제공된다면 현명한 소비자들이 있기에 정책이 더욱 정교해지고 발전할 수 있을 것이라 생각한다.

본 논문은 (1)에 기술된 퍼지 K-nearest neighbor(NN) 알고리즘의 확장인 interval 제2종 퍼지 K-NN을 제안한다. 제안된 방법에서는, 각 패턴벡터의 멤버쉽 값들에 불확실성(Uncertainty)을 할당하는 것에 의해 interval 제2종 퍼지 멤버쉽으로의 확장을 시도한다. 이러한 확장은, K의 결정에 존재하는 불확실성은 다루고, 조정할 수 있게 한다.

This is the first attempt to produce simultaneous surface current field from satellite altimeter data for the entire East Sea and to provide surface current information to users with formal description. It is possible to estimate surface geostrophic current field in near real-time because satellite altimeters and coastal tide gauges supply sea level data for the whole East Sea. Strength and location of the major currents and meso-scale eddies can be identified from the estimated surface geostrophic current field. The mean locations of major surface currents were explicated relative to topographic, ocean-surface and undersea features with schematic representation of surface circulation. In order to demonstrate the practical use of this surface current information, exemplary descriptions of annual, seasonal and monthly mean surface geostrophic current distributions were presented. In order to objectively classify surface circulation patterns in the East Sea, empirical orthogonal function (EOF) analysis was performed on the estimated 16-year (1993-2008) surface current data. The first mode was associated with intensification or weakening of the East Korea Warm Current (EKWC) flowing northward along the east coast of Korea and of the anti-cyclonic circulation southwest of Yamato Basin. The second mode was associated with meandering paths of the EKWC in the southern East Sea with wavelength of 300 km. The first and second modes had inter-annual variations. The East Sea surface circulation was classified as inertial boundary current pattern, Tsushima Warm Current pattern, meandering pattern, and Offshore Branch pattern by the time coefficient of the first two EOF modes.

Using methods of principle component analysis and pattern of analysis. Korean food supply pattern and its change (1962-1969) have been compared whit those of other 40 countries. 1) Among the 4 groups classified on the first and second principle components, Korea belongs to the highest crop grain dependent group of Asia. Although Korea is identified as one of the highest crop consuming countries among the group, a significant increase in the consumption of fruits and vegetables is noticed during the period. 2) According to the pattern of numerics analysis Korean food supply pattern (1969) is similar with those of Japan (1949), philippines, Taiwan, while is quite apart from those of U.S.A., W. Germany, France and Australia. 3) During the period the food supply pattern of Korea has been changed significantly toward the more common locations on the world food supply pattern map. Yet the location is far from the desirable one and its moving direction is characteristic, differing not only those of Europian countries but also Asian neighborhoods. this unique pattern should receive a careful examination and thus proper measures should be undertaken to take care of optimal nation's nutritional requirements.

This study describes the technique of the beam pattern measurement of array antenna for VHF band radar using drone and active beam pattern measuring device. There is no anechoic chamber for measuring the beam pattern of a large size antenna in the country. In this study, to test the antenna beam pattern characteristics of the developed VHF band radar, the antenna beam pattern characteristics were tested by Drone mounting an Active Beam Pattern Measuring Device. By comparing the results of the pre-simulation analysis with the measured results for the antenna, we could confirm that the beamwidth and side-lobe characteristics are satisfactory. Through the antenna beam pattern measurement technology using Drone and Active Beam Pattern Measuring Device, the beam pattern measurement technology of array antenna of low frequency band and large antenna for low band radar will be used.

The purpose of this study was to compare the pattern of two men's pants for education and two for industry, and to analyze the patterning method that is most suitable for the body shape of middle-aged men. As a result of appearance evaluation for 3D simulation, J pattern was evaluated as the best in most items, and H pattern was analyzed to be the most inappropriate. As a result of measuring the airgap, all four patterns of the waist circumference were evaluated to have very small airgap, and the J pattern had the smallest airgap for the pants. J pattern was analyzed as the most suitable pattern for middle-aged men's body shape by synthesizing the appearance evaluation of virtual wear, color distribution, sectional view, airgap, etc. However, in the case of J pattern, it was analyzed that the pants length needs to be modified. Since this study compared and analyzed only two patterns for education and two for industry, it is thought that the development of pants for middle-aged men should be developed through actual wearing experiments with J patterns.

Zero-waste is sustainable development for ensuring continuous interactions with the environment as well as for the next generations, while expanding across industries. Zero-waste fashion design does not necessarily mean that we should stop making clothes in order to reduce waste, but we consider the social values of sustainability regarding the environment, humans, and profit. In particular, in the pre-use stage of zero-waste fashion design, fashion designers play critical roles. The purpose of this study is to develop a methodology for the realization of zero-waste fashion design through establishing the typology of zero-waste pattern making (ZWPM) as well as exploring the practical implications of zero-waste fashion design. For the realization of zero-waste fashion design that draws from pattern-making principals, this study categorizes zero-waste fashion design into zero-waste pattern cutting (ZWPC) and non-pattern cutting (NPC). ZWPC is based on drafting patterns on a piece of fabric, which can enable the sharing of patterns and processes, while NPC requires little- or non-cutting/sewing in optimizing a piece of fabric, bringing the possibility of creating indefinite forms. ZWPC is sub-categorized into tailored and non-tailored, and NCP into draped and folded. Then, by implementing the typology in undergraduate design programs, this study tests and completes the design methodology for the realization of zero-waste fashion design.

The aim of this study is to examine how time-use and activities are affected by work hours. To achieve this, we focused on the weekday time-use of full-time workers in Seoul Metropolitan Area(SMA). The long 'work hours' are under active discussions since it is related to the quality of life. However, many Social researcher thought that problem of Korean working hours is linked to quality of life in the abstract. Because activity connects time-use and quality of life, the key point is activity under time constraints. Therefore, travel patterns should be understood by time-use and activity patterns. This study composes trip-chains from travel data of 2010 Household Travel Survey(HTS). Grouping trip-chains by activity patterns, we could make sure that a few of activities after work is affected by a short free time. This study has potential implications for the policy of work hours and traffic problems in the evening, and will provide new geographical perspective related to measuring quality of life.

The purpose of this study is to investigate experimentally the effects of type of superplasticizer on tensile behavior and cracking pattern of alkali-activated slag-based cementless composite. Three mixtures were prepared according to type of superplasticizer, and the compressive strength and tension tests were performed. Test results showed that differences of tensile strength, tensile strain capacity, and toughness of composites were up to 28.1%, 39.1%, and 66.2%, respectively, according to type of superplasticizer, although fiber balling or poor dispersion of fibers in fresh composites was not observed. It was also observed that the type of superplasticizer influenced number of cracks and maximum fiber bridging stress.
