  • Our residential architecture and furniture have developed their unique formative characteristics under the influence of the natural environment as well as under socio-cultural influence. In order to understand such characteristics of our residential architecture and furniture, we need to clarify similarities and differences through comparative study from various perspectives. The present study purposed to examine the effects of mutual relations among Yangban's residential architecture and their furniture in the Chosun Dynasty on their formative characteristics, to identify the formative characteristics of shapes, materials, colors, patterns and decorations found in the residential architecture and their furniture, and to make a comparative analysis of the formative characteristics of the residential buildings and their furniture. This research will provide a ground for reinterpreting our culture and help to apply Korean culture identity to today's interior and furniture design.

  • The statistical characteristics of typhoon wind speed records tend to have a considerable time-varying trend; thus, the stationary wind model may not be appropriate to estimate the wind characteristics of typhoon events. Several nonstationary wind speed models have been proposed by pioneers to characterize wind characteristics more accurately, but comparative studies on the applicability of the different wind models are still lacking. In this study, three landfall typhoons, Ampil, Jongdari, and Rumbia, recorded by ultrasonic anemometers atop the Shanghai World Financial Center (SWFC), are used for the comparative analysis of stationary and nonstationary wind characteristics. The time-varying mean is extracted with the discrete wavelet transform (DWT) method, and the time-varying standard deviation is calculated by the autoregressive moving average generalized autoregressive conditional heteroscedasticity (ARMA-GARCH) model. After extracting the time-varying trend, the longitudinal wind characteristics, e.g., the probability distribution, power spectral density (PSD), turbulence integral scale, turbulence intensity, gust factor, and peak factor, are comparatively analyzed based on the stationary wind speed model, time-varying mean wind speed model and time-varying standard deviation wind speed model. The comparative analysis of the different wind models emphasizes the significance of the nonstationary considerations in typhoon events. The time-varying standard deviation model can better identify the similarities among the different typhoons and appropriately describe the nonstationary wind characteristics of the typhoons.

브래지어의 맞음새 향상을 위한 패턴개발 연구 -l924세대용 언더웨어 브랜드 시판제품과의 비교분석- (A Study on the Development of Patterns for the Improvement of Fit of Brassiere - Comparative Analysis of Sample Brassiere with Products of Underwear Brands for 1924 Generation -)

  • In order to examine the characteristics of brassiere products for the 1924 generation brands on the market and grasp problems, we selected three 'comparative brassieres', each one from among the 1924 underwear brands with the highest recognition and sales profit, and then designed a 'sample brassiere' pattern(75A) with a similar shape to the comparative brassieres. We set up the "New Cup Grading Rule" with a view of reflecting the wearing effect that was varied according to cup sizes, graded the sizes of 75AA and 75B with this method, and made the sample brassieres in three sizes. We conducted the wearing evaluation and body measurements of 9 subjects after analyzing the patterns and characteristics of the sample brassieres and three comparative brassieres. As a result of the wearing evaluation, the sample and comparative brassiere 2, the dimensions and shapes were appropriate for the 1924 generation consumers and expressed an overall natural silhouette, showed satisfactory results in the entire evaluation questions. On the other hand, the comparative brassiere 1 and 3 that tended toward making a big change in the physical characteristics got unsatisfactory evaluations in the dimensions of the cups, clothing pressure, and bust silhouette. As a result of observing the variation in body dimensions by body measurements when nude and when wearing each brassiere and then summing it up with the score of the wearing evaluation, it was proven that too much change in body shape can create a negative image by upsetting the balance of the whole silhouette. Therefore, it is desirable to develop brassiere products with proper dimensions and clothing pressure that can make a physical change that harmonizes the overall bust silhouette and the position and shape of the breasts.

  • We survey the relation of fuzzy entropy measure and similarity measure. Each measure represents features of data uncertainty and certainty between comparative data group. With the help of one-to-one correspondence characteristics, distance measure and similarity measure have been expressed by the complementary characteristics. We construct similarity measure using distance measure, and verification of usefulness is proved. Furthermore analysis of similarity measure from fuzzy entropy measure is also discussed.

  • 이 연구의 목적은 "비교교육연구" 학술지에 게재된 논문을 중심으로 국내 교육과정 관련 비교교육 연구의 동향을 검토하고, 그 특징을 탈식민주의 관점에서 비판적으로 고찰하는 데 있다. 이를 위해 이 연구에서는 1995년부터 2016년까지 "비교교육연구"에 게재된 교육과정 관련 논문 61편을 분석하였다. 연구 결과, 우리나라 교육과정 관련 비교교육 연구는 주로 과거 식민 지배를 받았던 일본뿐만 아니라 북미와 유럽 중심의 서구 국가들의 교육과정과 교과서 관련 정책이나 내용을 벤치마킹하는 방식으로 이루어지고 있었다. 또한 다문화 사회로의 변화에도 불구하고 우리나라에 많이 거주하고 있는 외국인들의 국적인 중국과 베트남 등 아시아 국가들에 대한 연구는 찾아보기 어려웠다. 이러한 분석 결과에 기반하여, 이 연구에서는 비교교육 연구 대상국의 확대, 비교교육의 식민성 극복, 비교교육 연구자의 존재론적인 성찰 등이 필요함을 제시하였다.

  • Purpose of this paper is find the similarity and dissimilarity of Korean, Chinese and Japanese traditional furnitures for storage. Also this paper tries to have a comparative analysis on life style, characteristics of housing space and furniture's form of three countries. The study can be summarized as follows. First, space scale and seat levels of three countries are related to furniture's height and form, so that Chinese furniture have over scale than human, and Japanese furniture have the type of box for stacking. Second, the way of heating and materials of floors are concerned with the type of furniture's legs. Third, even if these dissimilarities, the aesthetic characteristics of three countries furniture would be a data base for making design identity of East Asian modern housing furniture.

  • The cultural identity of each nation has appeared as a major issue in this multi-cultural era, and needs to define It clearly through comparisons with other cultures have been raised. The purpose of this study is to figure out ‘similarity’ and ‘dissimilarity’ on design characteristics of traditional storage furniture in interior context of Korea, China and Japan. Comparative analysis of traditional furniture was conducted in two terms, in terms of inner space, first, spatial elevation and front patterns, second, flooring materials of the interior space and types of furniture legs. Result of first comparative analysis showed that composition of windows, one of the major decorative elements of interior space, positively influenced on furniture, and reflected unique patterns of each country. Second comparative analysis showed that structures and shapes of traditional furniture vary depending on flooring materials. As a result of it, Korean furniture has the structure of ‘punghyeol’ and Chinese furniture has the structure of ‘aja’ with ‘takni’ , a combination of legs. In contrast to the two countries, Japanese furniture has rarely legs. The result of analysis is expected to act a role of establishing the cultural identity of our own country.

  • Less mature nuclear reactor technologies are characterized by a greater uncertainty due to insufficient detailed design information, operational data, cost information, etc., but the expected performance characteristics of less mature options are usually more attractive in comparison with more mature ones. The greater uncertainty is, the higher economic risks associated with the project realization will be. Within a comparative evaluation of less and more mature nuclear reactor technologies, it is necessary to apply economic risk measures to balance judgments regarding the economic performance of less and more mature options. Assessments of any risk metrics involve calculating different characteristics of probability distributions of associated economic performance indicators and applying the Monte-Carlo method. This paper considers the applicability of statistical risk measures for different economic performance indicators within a trial case study on a comparative evaluation of less and more mature unspecified LWRs. The presented case study demonstrates the main trends associated with the incorporation of economic risk metrics into a comparative evaluation of less and more mature nuclear reactor technologies.
