  • The analysis of exotic style in domestic fashion brand items aims to offer the ideas necessary for the style and item developments and to analyze exotic images and styles accepted in domestic fashion market. Therefore this study analyzed the domestic fashion brand items and categorized the main exotic factors and styles so that would catch on to its characters and appearance frequency. As for the research method of this study, the frequency and content multi-dimensional analysis were used in the investigation of the exotic images appearing in the domestic fashion brands. The styles of exotic image in domestic fashion brand items are 'natural' style, 'primitive' style, 'ethnic' style, and 'maximalism' style. Also, the main exotic factors in each exotic style were composed of a few exotic images such as 'natural', 'primitive', 'ethnic', 'romantic', 'elegance', 'splendid', 'seductive', 'retro', 'traditional', 'classical', 'bohemian', 'vintage', 'kidult', 'artistic', 'extreme compromise', and 'modern'.

  • 본 연구는 2002년부터 2009년까지 국내에서 발생한 돌풍에 대한 시계열 및 공간분포를 분석하였다. 태풍 기간 동안에 발생한 돌풍에 대해서는 제외하였으며, 지형에 의한 풍속 할증 효과는 KBC 2005 기준을 적용하여 보정하였다. 분석 결과, 돌풍 발생 빈도는 해안지역을 따라 높은 빈도가 나타났으며, 대상 기간 중 최대 286회의 발생 빈도를 보였다. 본 연구에서는 뇌우에 의한 돌풍과 종관 기상에 의해 발생한 돌풍의 시계열 분포의 비교를 통해 뇌우에 의한 돌풍의 불확실성이 높음을 확인하였다. 또한 누적운량과 뇌우 돌풍의 공간적 상관분석을 통해 두 인자간 높은 상관관계가 있음을 근거로 하여 돌풍에 대한 공간적 위험도를 평가하는데 활용할 수 있음을 제시하였다.

  • In order to satisfy with the clear visibility without any difficulties such as blurring and tailing, the high refreshing rate technology and fast response time of LC itself were applied to TFT-LCDs. In proportion to the decrease of holding time of 1 frame, the fast transition of LC behavior was necessary to both maintain the luminance and minimize the tailing appearance. The introduction of a new LC mixture for faster response times was realized by the good combination of newly introduced dielectrically neutral LC material so called 'Super Low Viscosity' (SLV) and highly polar $CF_2O-linkage$ LC material. This resulted in about a 20% reduction in the ${\gamma}_1$ of the new LC mixture compared to the references. In accordance with a new LC mixture with low ${\gamma}_1$, fast response time of 5ms has been made for S-IPS LCD TV application. Consequently, by applying the high frame frequency of 120Hz driving alongside the 5ms response time characteristics, the MPRT value was reduced by half.

  • The potential-induced charge transfer of the dye (Bu4N)2[Ru(dcbpyH)2-(NCS)2] (N719) on Au, Ag, and Cu electrode surfaces has been examined by surface-enhanced Raman scattering (SERS) in the applied voltage range between 0.0 and ?0.8 V. N719 is assumed to have a relatively perpendicular geometry with its bipyridine ring on the metal surfaces. A strong appearance of the carboxylate band at ~1370 cm-1 indicates that the carboxyl group will likely be deprotonated on the metal surfaces. As the electric potential is shifted from ?0.8 to 0.0 V, the ν (NCS) band at ~2100 cm-1 on the electrode surfaces appears to undergo a shift in frequency and intensity change. This indicated that the charge transfer between the dye and metal electrode surfaces had occurred. Electric-field-dependent charge transfer differs somewhat depending on the type of metal surfaces as suggested from the dissimilar frequency positions of the ν (NCS) band.

  • 본 연구에서는 행렬 분해 (Matrix Factorization)를 이용하여 음성 스펙트럼의 부분적 특정을 나타낼 수 있는 새로운 음성 파라마터를 제안한다. 제안된 파라미터는 행렬내의 모든 원소가 음수가 아니라는 조건에서 행렬분해 과정을 거치게 되고 고차원의 데이터가 효과적으로 축소되어 나타남을 알 수 있다. 차원 축소된 데이터는 입력 데이터의 부분적인 특성을 표현한다. 음성 특징 추출 과정에서 일반적으로 사용되는 멜 필터뱅크 (Mel-Filter Bank)의 출력 을 Non-Negative 행렬 분해(NMF:Non-Negative Matrix Factorization) 알고리즘의 입 력으로 사용하고, 알고리즘을 통해 차원 축소된 데이터를 음성인식기의 입력으로 사용하여 멜 주파수 캡스트럼 계수 (MFCC: Mel Frequency Cepstral Coefficient)의 인식결과와 비교해 보았다. 인식결과를 통하여 일반적으로 음성인식기의 성능평가를 위해 사용되는 MFCC에 비하여 제안된 특정 파라미터가 인식 성능이 뛰어남을 알 수 있었다.

  • The object of this study lies in reviewing of the western costume history in the light of the negative regulations concerning costumes and adornments. Readings related with the subject lead to the following findings; 1. the principal purpose of the sumptuary laws has relationship with the social stratification of the feudalism and the frequency of their occurrence is related with the formation of feudal system, its decline, the appearance of imperial regimes and the start of civil revolutions. 2. Sumptuary regulations spread westward with the flow of civilization, eg., in the sequence of Italy, swiss, France, Britain and new world. 3. Sumptuary laws are also found in abundance in the english colonies of America, and their object seems to be rather of the moral concern than class distinction of economical restriction.4. The reviewed sumptuary regulations are concerned with : A. Material gold or silver clothes, silks, ermine, marten or miniver furs, velvets, laces and embroies. B. Colors-Purple, scarlet and red. Other colors do not show consistent pattern of color-status symbol; C. Form-Length and width of headdresses, shoes, collars, trains or hoops. E. numbers of dresses allowed to be worn.

  • This study aimed to classify the lifestyles of 1020 college students, and to analyze the effect of the lifestyles on the usages of credit card, price perception, purchasing satisfaction and the number of new clothing. The number of credit cards, total payment of credit cards and the attitude to credit card were different by the 7 clusters of college students, but the frequency of credit card use, the amount of cash service and arrear ages were not different. The perception to the apparel price, purchasing satisfaction, and the degree of clothing purchasing varied according to the lifestyle clusters. For example, 6th cluster being highest in the pursuit of appearance showed the highest amount of credit cards usage significantly and tendency of highest arrearage, and used credit cards mostly in clothing purchase.

  • Purpose: This study was to understand the major subjects of the recent nursing research in Nursing administration from keywords. Method: Keywords of journals were extracted and the frequency of the appearance of each key words was sorted by a descending order. Results: A total of 327 key words were used. The most frequently used key words were 'Job satisfaction', 'Organizational commitment', 'Leadership'. Out of them, organizational culture, nursing performance, nursing classification, patient satisfaction, and ethics appeared most frequently in descending order. Conclusion: From the above it can be noted that many nursing administration concepts were handled in the papers. But there were not enough papers on the characteristics of the Nursing administration. It is suggested that in depth research be made on 'Nursing error', 'Nursing informatics', 'Web based learning'.

  • Identifying quality attributes with the greatest value to the residents is important if the Continuing Care Retirement Community (CCRC) is to increase the frequency of residents' dining. However, it is not known which specific attribute is relatively more important than others to evaluate foodservice. The purpose of this study is to identify the relative importance of food and service quality attributes in the evaluation of foodservice in CCRe. This study surveyed the independent living residents of three CCRCs in the Midwestern states. Respondents placed great importance on taste and flavor of food which has the highest percentage of utility range ($28.28\%$) and the second greatest on appearance of the server ($23.46\%$) . The important attributes were ultimately used to predict the most preferred choice of food-service for residents. Knowledge of the importance of the attributes would enable the foodservice managers in CCRCs to manipulate those attributes to enhance the residents' perceptions of quality and identify strategies for continuous improvement.
