Placeness forms the traits unique to certain areas inducing people to visit there and purchase goods related to the place. The purpose of this study is to survey fashion images linked with placeness, by examining on-line and off-line fashion goods which claim the placeness. Hong-dae area in Seoul is selected for the case study, and the fashion goods claiming Hong-dae style or Hong-dae fashion are selected in order to analyze the fashion images. Hong-dae area, which was known for its art scenes and small restaurants in the 1980s, has been flourished its postmodern style cafes formed as yuppies-style consumer space in the 1990s. Foreign influenced subcultures were adopted, mimicked and mixed. Afterwards, dance clubs and live clubs gathered around this area. Recently, various local events to enhance the place identity such as "freemarket" and festivals are hosted by the local community. Based on the historical and regional background, the placeness of Hong-dae area is characterized with its artistry, counter-culturalism, and commercialism. The fashion images related of Hong-dae area fashion can be characterized as avant-garde image, art & craft image, kitsch image, vintage image, sexy casual image, and pop art image. The avant-garde image and the art & craft image are related with altistry and counter-culturalism. Kitsch image is related with the artistry, counter-culturalism, and the commercialism. Vintage image is related with artistry, counter-culturalism and commercialism. Sexy casual image is known to have commercialism of Hong-dae area, while Pop art image has its artistry and commercialism.

This study has examined the shift in fashion styles in Korea by analyzing trends in fashion environment and fashion image by seasons in Korea to understand the domestic fashion flow from 2000 to 2006. Since 2000, with the well-being trend, polarization of consumption, preference in luxury orientation, and digital revolution, consumers became individualized and detail oriented. They also became smart consumers equipped with information and knowledge in making choice and purchasing products suiting their taste. To satisfy the consumer trend, fashion market also saw changes such as expansion of advanced distribution, totalization of brands, growing of on-line shopping mall, expansion of outdoor-wear market, and formation of masstage(mass+prestage) market. Fashion images in domestic women's wear since 2000 are analyzed as classic, elegant, minimalism, romantic, bohemian & vintage, ethnic, glam, girlish, kidult, sportive, femiculine, military, and lingerie image. Classic, romantic, and bohemian & vintage are the images that were popular throughout 2000 to 2006. Fashion images of domestic women's wear showed changes in three periods: Sportive image was popular in FW 2002; military image in SS 2003 to SS 2005; and femiculine, glam, and minimalism images in FW 2005 to FW 2006. Through information and detail-oriented emotion, the wide-ranging acceptance of global trends, the consumer tendency towards purchasing products quickly and conveniently, the speedy supply of trendy products both on-line and in-store, and the evolution of the fashion market towards providing one-stop shopping and a cultural space, different fashion images have all emerged at the same time in Korea. It looks like this phenomenon is set to continue for a while.

To compare several porcelains made by various manufacturers in shrinkage after firing and investigate the effect of condensation on shrinkage, specimens were prepared and the volume of each body was measured by the phase-shifting profilometry. Baseplate wax was cut by $2.5cm{\times}2cm$ and cast in nonprecious metal(Verabond, U.S.A.), then any surfaces of specimens were abrased and polished on the SiC abrasing papers, preparing 120 specimens. Specimens were divided into six groups according to the porcelain used, and the porcelain used in each group were as follows. Group I : Ceramco dentin porcelain Group B : Creation dentin porcelain Group III : Creation margin porcelain Group IV : Vintage margin porcelain Group V : Vita dentin porcelain Group VI : Vintage dentin porcelain Porcelain was built up on the metal plates using a small spoon and then solution matching to each porcelain was added. The six groups are subdivided into a and b. In subgroup a, only excessive solution was absorbed with tissue and in subgroup b, porcelain was condensed sufficiently. When build-up was completed, the shape was measured using the phase-shifting profilometry. After that, specimens were fired in the furnace programed for each porcelain and then their changed shape were measured again. Using the difference between the two above measurements, the ratio of shrinkage was calculated. Obtained results were as follows ; 1. Regardless of condensation, the volume of fired specimens were not different significantly between the two subgroups a and b in the same group. 2. The ratios of shrinkage were significantly higher in the groups porcelain built-up was condensed than in the groups not condensed 3. The ratios of shrinkage were in the range of 36.81-27.19% in the groups porcelain built up was condensed and 44.52-37.54% in the other groups not condensed.

본 연구에서는 산업연관표를 통해서 특정연도(1990년) 기술의 진부화 정도를 측정하고, 노동생산성과의 연관성을 밝힘으로써 체화가설(embodiment hypothesis)을 검증한다. 이는 기술에 강한 경제적 의미를 부여한 Salter(1969)의 주장에 근거한 것으로, 경제적 잉여율의 감소를 기술진부화 정도로 보았다. 분석대상은 우리나라 제조업에 속한 주요 업종인 음식료, 섬유의복, 화학, 비금속광물, 철강, 금속제품, 일반기계, 전기전자, 정밀기기, 수송기계 등이다. 연구결과, 우리나라 제조업 전체에 대해서 일률적으로 체화가설의 성립여부를 판단하기는 어려웠다. 그러나 제조업 주요 업종 중 섬유의복, 화학, 비금속광물, 금속제품, 전기전자, 수송기계 등의 산업에서는 체화가설이 성립함을 확인하였다. 즉 이들 6개 산업에서는 기존 자본설비에 현대적인 새로운 자본설비가 연속적으로 도입됨에 따라 특정시점에서 자본설비에 체화되어 도입된 기술은 진부화 하지만, 시현되는 노동생산성은 증가하는 것으로 분석되었다. 따라서 개별기업들은 설비투자에 대한 의사결정 시에 관련설비에 체화된 기술진보에 관한 정보를 적극 고려해야 하며, 정부는 R&D지원 일변도의 정책에서 벗어나 체화기술진보 효과가 큰 산업에 대해서는 설비투자를 지원하는 정책도 고려해야 한다.

This study is to review, in the social and cultural context, the main causes for the sportism that prevails in modern fashion, and to analyze the typical expressions in the domestic fashion. Many factors attribute to the advent of sportism such as rapid development and cultural changes toward sports, increase in leisure time and abundant opportunities, new fashion materials resulting from new technologies, emerging youth culture and increasing preference for such culture, and the postmodernism. With this background, sportism, which has been appearing in the domestic fashion, falls into 5 categories as follows based on the type of its expression. “Urban Street Sportism” is affected by the new sports culture of urban young people, which is characterized such that body line is disregarded with over-sized garment in layered style without considering T.P.O. concept. “Romantic Sportism” applies colors, fabrics and details of romantic images to sporty items, or culminates the feminine and elegant sportism by using the sporty fabrics and details along with romantic items. “Vintage Sportism” is characterized by its well-refined, high quality expression of naturally worn for long time, which is affected by the postmodernism. “Urban Utility Sportism,” which is developed with such design factors as fabrics, styles, details and colors with emphasis on their utility and functionality, explicitly accommodates the changed modern life styles particularly in urban areas. Lastly, the military image, which was developed during the Iraq War along with simultaneous anti-war activities, and the peace messages, which deliver the mankind's hope for the world peace and social wellness, formulate the “Military Sportism”.

When the number of items of same type of industrial property is quite large, calculating depreciation for a group of such item may be more efficient than depreciating each item separately. Also, predicting the service life of a specific individual unit is very difficult to do with any degree of accuracy. Estimating the probable average service life (PASL) of many units (or dollars) is not an easy task; however, an average life of many units can probably be predicted with a much higher degree of accuracy than the life of some particular unit. Using the average of many units allows for some units having relatively short lives and some units having relatively long lives without specifying whether a particular unit will have a short or a long life. If the life of each vintage in an account are not estimated, then the broad group procedure can be used. The broad group procedure depreciates the several vintage in an account as a single group. The PASL for this procedure is the estimate of the average of lives of the individual dollars in the group. If the estimated PASL's of the vintages are not the same, then a weighted average PASL would have to be calculated for each calendar year. In this paper, we illustrate the calculations of accrual rates and the annual depreciation charge for each of the calendar years by the broad group depreciation procedure.

본 연구는 2007년부터 2017년까지 신규로 결성이 되어 2022년말 기준 청산이 완료된 국내 벤처펀드 205개(청산 금액 7.25조)를 대상으로 투자성과에 영향을 미치는 요인에 대하여 실증분석을 하였다. 사모펀드의 특성상 실증데이터를 확보하기가 매우 어려우며, 특히 코로나 이후 청산이 완료된 데이터를 구하기는 더더욱 어려운 실정이다. 그럼에도 불구하고, 최근 10년 이내 가장 최신의 데이터를 활용하여 국내 벤처펀드의 투자수익률에 미치는 영향을 분석했다는 것은 상당한 의미가 있다고 하겠다. 본 연구는 벤처펀드의 투자 성과에 미치는 요인을 외부 환경 요인과, 내재적 요인으로 구분하여 연구를 진행 하였다. 벤처펀드의 성과에 미치는 외부 환경요인으로는 '경기사이클', '주식시장', '벤처시장', '회수시장'으로 구성하여 분석하였고, 내재적 요인으로 운용사 역량을 '운용사 업력', '운용사 전문인력', '운용 규모(AUM)'로, 펀드 구조로는 '펀드 크기(Size)', '펀드 기간(Length)'로 구분하여 비교 분석하였다. 분석 결과를 요약하면 다음과 같다. 첫째, 경기사이클을 잘 나타내는 국고 3년 금리는 펀드성과에 유의한 영향을 미치는 것으로 확인이 되었다. 둘째, 펀드 결성후(後) 코스닥 3개월 평균 지수 상승률은 펀드 성과에 통계적으로 유의한 정(+)의 영향을 미치는 것으로 나타났다. 셋째, 벤처펀드 청산 시점의 경쟁 강도를 나타내는 IPO_개수는 펀드 성과에 부정적인 영향을 미치는 것으로 나타났다. 넷째, 운용사의 AUM 규모가 클 수록 펀드 수익률이 양호한 것으로 나타났다. 끝으로, 벤처펀드의 수익률이 결성연도에 따라 차이를 보이고 있는 것으로 나타나서 일반인들이 벤처펀드 투자를 고려 할때는 '외부 환경요인'과 '펀드 내재적 요인'과 더불어 결성연도(Vintage)를 고려한 투자 포트폴리오를 구성하는 것이 매우 유효한 투자 전략이 될 것이라 판단된다.

To analyze the design of Christian Dior, 216 pieces of Dior's works were collected and studied from the COLLECTION(Seoul: Dong Ah TV) from 2003 to 2005. The result is as follows. In recent three year period, Christian Dior maintained the feminine image and implemented different additions such as sexy, ethnic, avant-garde and casual image in every season. Also, to reflect a new trend or fashion sense, images of ethnic, retro, hippie or vintage were applied. In using color, different main color(YR, R, Y, BG, RP, B) were chosen every season to pursue variations. For the pattern usage, feminine beauty was presented by numerous applications of flowered pattern. Also the practice of pattern and hue in different rations in every season pursued variations in design.

In this paper, we propose a new data fusion method to improve the performance of individual prediction models for time series data. Individual models used are ARIMA and neural network and their results are combined based on the weight reflecting the inverse of EWMA of squared prediction error of each individual model. Monte Carlo simulation is used to identify the situation where the proposed approach can take a vintage point over typical fusion methods which utilize MSE for weight. Study results indicate the following: EWMA performs better than MSE fusion when the data size is large with a relatively big amplitude, which is often observed in intra-cranial pressure data. Additionally, EWMA turns out to be a best choice among MSE fusion and the two individual prediction models when the data size is large with relatively small random noises, often appearing in tax revenue data.
