The purpose of this study was to investigate the relationship between Chanel design and her Costume jewelry in 1920's-1930's through documentary studies. According to the study the result was as follows: 1. Chanel's esthetic in the field of Fashion Design bore the double stamp of "elegance" and 'simplicity' 2. Chanel changed the concept of costume jewelry. Chanel's great innovation was that she let 'fake' jewels always keep the intrinsic value of 'real' ones. 3. The simplicity of her perfectly tailored suit was Paradoxically overwhelmed by a fan-tastic array of jewels. The relationhship be-tween Chanel design and her costume jewelry was not able to be seperated. Chanel was a fashion leader fifty years ago and the name "Chanel" will be at the forefornt of fashon fifty years from now. The image of quality will always remain the same in the futures.

Purpose - This study examines the impact of oil price volatility on economic activities in Korea. The new millennium has seen a deregulation in the crude oil market, which invited immense capital inflow into Korea. It has also raised oil price levels and volatility. Drawing on the recent theoretical literature that emphasizes the role of volatility, this paper attends to the asymmetric changes in economic growth in response to the oil price movement. This study further examines several key macroeconomic variables, such as interest rate, production, and inflation. We come to the conclusion that oil price volatility can, in some part, explain the structural changes. Research design, data, and methodology - We use two methodological frameworks in this study. First, in regards to the oil price uncertainty, we use an Exponential-GARCH (Exponential Generalized Autoregressive Conditional Heteroskedasticity: EGARCH) model estimate to elucidate the asymmetric effect of oil price shock on the conditional oil price volatility. Second, along with the estimation of the conditional volatility by the EGARCH model, we use the estimates in a VECM (Vector Error Correction Model). The study thus examines the dynamic impacts of oil price volatility on industrial production, price levels, and monetary policy responses. We also approximate the monetary policy function by the yield of monetary stabilization bond. The data collected for the study ranges from 1990: M1 to 2013: M7. In the VECM analysis section, the time span is split into two sub-periods; one from 1990 to 1999, and another from 2000 to 2013, due to the U.S. CFTC (Commodity Futures Trading Commission) deregulation on the crude oil futures that became effective in 2000. This paper intends to probe the relationship between oil price uncertainty and macroeconomic variables since the structural change in the oil market became effective. Results and Conclusions - The dynamic impulse response functions obtained from the VECM show a prolonged dampening effect of oil price volatility shock on the industrial production across all sub-periods. We also find that inflation measured by CPI rises by one standard deviation shock in response to oil price uncertainty, and lasts for the ensuing period. In addition, the impulse response functions allude that South Korea practices an expansionary monetary policy in response to oil price shocks, which stems from oil price uncertainty. Moreover, a comparison of the results of the dynamic impulse response functions from the two sub-periods suggests that the dynamic relationships have strengthened since 2000. Specifically, the results are most drastic in terms of industrial production; the impact of oil price volatility shocks has more than doubled from the year 2000 onwards. These results again indicate that the relationships between crude oil price uncertainty and Korean macroeconomic activities have been strengthened since the year2000, which resulted in a structural change in the crude oil market due to the deregulation of the crude oil futures.

최근 인공지능, 딥러닝, 빅데이터 등 4차 산업의 핵심 분야에 대한 관심이 커지면서 기존의 의사결정 문제를 전통적인 방법론의 한계점을 최소화하는 과학적 접근 방식이 대두되고 있다. 특히 이런 과학적인 기법들은 주로 금융 상품의 방향성을 예측하는데 사용되는데 본 연구에서는 사회적으로 관심이 높은 아파트 가격의 요인을 자기조직화지도를 통해 분석하고자 한다. 이를 위해 아파트 가격의 실질 가격을 추출하고 아파트 가격에 영향을 주는 총 16개의 입력 변수를 선정한다. 실험 기간은 1986년 1월부터 2021년 6월까지이며 아파트 가격의 상승 및 횡보 구간을 나눠 각 구간 별 변수들의 특징을 살펴본 결과, 상승 구간과 횡보 구간의 입력 변수의 통계적 성향이 뚜렷하게 구분되는 것을 알 수 있었다. 더불어 U1~U3 구간이 N1~N3 구간에 비해서 변수들의 표준편차가 상대적으로 크게 나왔다. 본 연구는 중장기적으로 상승과 하락이라는 큰 주기를 갖고 있는 부동산에 대해서 현재 시점의 현황을 정량적으로 분석한 것에 의미가 있으며 향후 이미지 학습을 통해 미래 방향성을 예측하는 연구에 도움이 되기를 기대한다.

Purpose - In this study, we investigate determinants of hedging with derivatives and its effect on firm value and firm risk for Korean firms. Design/methodology - To avoid the endogeneity problem pointed out in previous studies, we use a two-stage analysis by using gains and losses from derivatives as instrument variable for hedging with derivatives. Findings - Our analysis on the determinants of hedging shows that firms that are more leveraged and less profitable, and with more growth opportunities are likely to hedge through derivatives. Additionally, large firms, firms less diversified into industry, and firms more diversified geographically are likely to use derivatives. Our two-stage analysis shows that indicators of hedging with derivatives have an insignificant effect on firm value, and the indicator of futures/forwards use and of swaps use have significant negative effect on firm value. Whereas, the extent of hedging with derivatives has positive effect on firm value for all types of foreign currency derivatives, which suggests that moderately low hedgers use derivatives inefficiently, but extensive hedgers use derivatives properly. With regard to firm risk, hedging with derivatives increases market-based risk, but decreases accounting-based risk. Thus, we conclude that Korean firms use derivatives to manage operational volatility rather than to manage market risk, and accounting-based risk reduction through hedging is not directly translated into higher firm value. Originality/value - This is not the first study to investigate hedging behavior of Korean firms, but the sample period that that this study analyzed is the longest and various method are used to control the endogeneity problem. We investigate not only total foreign currency derivatives but also by types of derivatives, including futures/forwards, options, and swaps.

This research aims to explore the influence of early entrepreneurial education on cognitive and non-cognitive abilities of male sixth-grade primary school pupils using a randomized pretest-posttest control group design. A total of 45 students were randomly allocated to experimental, active-control, and control groups using a multi-stage random selection procedure. The experimental group was taught entrepreneurship using the Bizworld entrepreneurship education package. The active control group did not get entrepreneurship education but was instructed on a non-entrepreneurship-related issue (hygiene). The Control group received no instruction. The findings revealed that early entrepreneurial education skills impacted noncognitive abilities (such as risk-taking propensity, creativity, self-efficacy, persistence, and need for achievement). Early entrepreneurship education seems to be an effective technique for developing children's non-cognitive abilities in the late years of primary school. As a result, entrepreneurship education may be taught in primary schools, emphasizing the development of non-cognitive abilities, which will affect children's individual, educational, social, and vocational futures and can have long-term advantages for students, families, and society.

This research is the trial for the computation of the ease-rate for the bodice pattern. The result of the analysis about the cross section figures of garment space by using a 3-D measuring instrument is that: The garment space of each bodice by each body size is definite. In the figure of cross section of the basic lines, an area of cross section of garment space and length of cross section of garment space are not increased in proportion to an area of cross section of the body. The ease rate is the same no matter that flat-rate of the body is same or different. The ease-rate is computed by length of cross section of garment space that is in proportion to the radius of the body.

This paper designs the dynamic symbol automatic trading system in Korean option market. This system is based on Multichart program which is convenient and efficient system trading tool. But the Multichart has an important restriction which has only one constant symbol per chart. This restriction causes very useful strategies impossible. The proposed design uses global variables, signal chart selection and position order exchange. So an automatic trading system with dynamic symbol works on Multichart program. To verify the proposed system, BS(Buythensell)-SB(Sellthenbuy) strategies are tested which uses the change of open-interest of stock index futures within a day. These strategies buy both call and put option in ATM at start candle and liquidate all at 12 o'clock and then sell both call and put option in ATM at 12 o'clock and also liquidate all at 14:40. From 23 March 2009 to 31 May 2010, 301-trading days, is adopted for experiment. As a result, the average daily profit rate of this simple strategies riches 1.09%. This profit rate is up to eight times of commision price which is 0.15 % per option trade. If the method which raises the profitable rate of wining trade or lower commission than 0.15% is found, these strategies make fascinated lossless trading system which is based on the proposed dynamic symbol automatic trading system.

Clearing trace of symbol which was gone with a series of pre-modern architecture history since the modern architecture (pursuing true nature from tradition which is repeated and imitated unconsciously). That is, What is the course of deconstruction? In the early part of the 20th century, We still accept the necessity of decoration in spite of its existence at one time being threaten. This means, even though symbolism in architecture has relative importance by situation of Times, it plays an important role to add the past to current style through 'Symbol'. The history of Times, a carrier which reflects Present on New Futures, makes memory by gathering data but we can not amplify our historical imagination with only data. Data is a past memory and evidence but we can not substitute that for historical experience. And it is difficult for future generations who don't live through that history to change their historical recognition with recollecting memories. They have to draw history with data but it is very limited in itself. However, They can collect historical memory through symbol in architecture. In this study, We pay attention to the symbolism of a memorial hall architecture. So We'll analyze dichotomy concept of Barthes's signifiant and signifie, visual sign and course of symbolic meaning on basis of Daniel Libeskind's Jewish Museum.
