  • We estimate consumer price indexes of eight major cities from 1907 to 1939, and then integrate them into a national level one. The data mainly came from the Statistical Yearbooks of the Government-General of Colonial Korea, and if necessary, we supplement them using wages and unit prices of public utility charges which are used as the price of housing and various services. We apply Laspeyres index method, and the composition ratios of consumption expenditure estimated by the commodity flow method are used as weights. The price indexes of 12 item groups as well as aggregate one are also calculated. In case of Seoul, it is possible to calculate the consumer price index from 1907 to 2009, showing a century-long pattern. This consumer price index is critical for measuring the real income and expenditure before the liberation.

  • With the escalation of global trade, the Chinese commodity futures market has ascended to a pivotal role within the international shipping landscape. The Shanghai Containerized Freight Index (SCFI), a leading indicator of the shipping industry's health, is particularly sensitive to the vicissitudes of the Chinese commodity futures sector. Nevertheless, a significant research gap exists regarding the application of Chinese commodity futures prices as predictive tools for the SCFI. To address this gap, the present study employs a comprehensive dataset spanning daily observations from March 24, 2017, to May 27, 2022, encompassing a total of 29,308 data points. We have crafted an innovative deep learning model that synergistically combines Long Short-Term Memory (LSTM) and Convolutional Neural Network (CNN) architectures. The outcomes show that the CNN-LSTM model does a great job of finding the nonlinear dynamics in the SCFI dataset and accurately capturing its long-term temporal dependencies. The model can handle changes in random sample selection, data frequency, and structural shifts within the dataset. It achieved an impressive R2 of 96.6% and did better than the LSTM and CNN models that were used alone. This research underscores the predictive prowess of the Chinese futures market in influencing the Shipping Cost Index, deepening our understanding of the intricate relationship between the shipping industry and the financial sphere. Furthermore, it broadens the scope of machine learning applications in maritime transportation management, paving the way for SCFI forecasting research. The study's findings offer potent decision-support tools and risk management solutions for logistics enterprises, shipping corporations, and governmental entities.

  • Cultural goods is carrying nature and value above-mentioned a commodity to what a cultural element was commercialized. And it produced for the purpose of manufacture for popular sales and supply, and holding commercial character. Specially, cultural goods of a museum keeps a good memory to a sightseer, and broaden an educational experience, and the source of profit becomes it to a seller a producer. This cultural goods as they all include the artistic historical figurative background that they are displayed directly and got twisted up to collection have background which became a motive. Cultural goods can acquire cultural difference in globalization and have to be based on the soil of cultural heritage, starting around various cultural materials through practical value to a modern life. Internationally, cultural goods using a culture material development have competitiveness of nation as in it. Therefore, Baekje cultural goods need national and positive aid from the government with the customer satisfaction index considering the modern design, an age group, an internal and external commodity as the difficulty of various commodity development and managing museum shop. Furthermore, like overseas museum shop, if we are practically using on-off line, continuous promoting our commodity, and marketing strategy such as a membership system when buy our cultural goods, a special discount event etc., we can contribute to activate local economy as a museum shop when we have responsibility of the function and the part.

  • The purpose of this study is to analyze the fetishist characteristics and the aesthetic values of glamour style based on the premise that fetishism is the theoretical root of glamour style expressed in fashion throughout history. The following results are from analysing fetishist characteristics of glamour style. First, luxury was analysed from an angle of commodity fetishism. Every culture develops images and stories that portray a world in which its ideals are realized: a paradise, a utopia, a golden age, etc. Consumer goods often serve as 'bridges to these ideals'. People thus can fantasize about owning the perfect life. Crucially, however, they must never get everything they picture. That is why luxuries often take on displaced meaning. Glamour gives the displaced meaning visual form, making it beautiful and real. Second, the attention on the glamour of luxury goods as a bridge to ideals is connected to the glamour icon who is simultaneously a consumer of these luxury goods and a producer of cultural goods. Glamour icons including the courtesan of the late 19th century, the actress of the 1930s' Hollywood golden age and today's celebrities appear to efface the traces of production and create fetishist images in culture. Through this artificial principle, the commodity-cum-glamour icon comes to life as a splendid image of spectacle. Third, masquerade and seduction were analysed from an angle of sexual fetishism. A magnificent image of masquerade as sexual fetishism is often equated with femininity, especially in Hollywood movies, because the artificial seduction of the feminine -namely glamour- can be effected by the absence or silence of being. That is to say, the aesthetic revelation of femininity coincides with the fleshing out of artificial signs. Masquerade and the seduction of the feminine are connected with glamour's artificial sensuality from this point. Fourth, since 1980's when homosexuality as sexual deviation resurfaced as a hot topic, sexual ambiguity and bisexual image have gained attention as perverse sexuality. Next came queer theory, which reduced gender itself to a matter of surface rather than depth. According to queer theory, gender itself can be revealed as a kind of drag act. Drag's imitative performance may reveal that womanliness is just about 'dragging up'. Queerness as a decadent play makes a connection with the wicked origins of glamour. From these characteristics, four aesthetic values were deduced: ostentatious luxury and mysterious idolatry by commodity fetishism, artificial sensuality and playful queerness by sexual fetishism.

  • As strategies for creating profits are differentiated by the national economic system and development strategies related to firms' geographical scope, they depend on the spatial contexts and product characteristics. In this perspective, strategies for the profit creation of Korean textile and clothing FDI firms invested in Vietnam has involved in the geographical differentiations in accordance with the development path of transitional economies, changes in institutional environments and the characteristics of products. Therefore. the main purpose of this research is to identify the way in which they have their own identity in transitional economies by investigating business pattern, commodity chain and extra-firm relations, which are related to institutional dynamics in Vietnam. There are two main characteristics of Korean textile and clothing FDI firms in Vietnam. The first is that all business activities involved in the commodity chain of them from R&D to production is controlled by global retailer and distributors, which is the buyer-driven commodity chain and the typical commodity chain of the textile and clothing industry. The second could be defined as over- or unforced embeddedness into the institutional legacy of the Soviet system, because they have been incorporated into pre-existing networks based on reciprocal relations in Vietnam.

  • Japan's frozen shrimp future market is the only fisheries future commodity market in the world. This empirical study examines the lead and lag relationship between Japan frozen shrimp spot and future markets using the daily prices from August 1, 2002 to December 31, 2005. Frozen shrimp future contract is listed on Japan Kansai Commodities Exchange. Japan imports approximately 250,000 tons of frozen shrimp annually, of which just under 70,000 tons, nearly 30%, are black tiger shrimp. Approximately 90% of black tiger shrimp are caught in Indonesia, India, Thailand and Vietnam, and the two largest consumers of these shrimp are Japan and the U.S.A. Kansai Commodities Exchange adopts the India black tiger shrimp as standard future commodity. We use unit root test, Johansen cointegration test, Granger causality test, Vector autoregressive analysis and Impulse response analysis. However, considering the long - term relationships between the level variables of frozen shrimp spot and futures, we introduced Vector Error Correction Model. We find that the price change of frozen shrimp futures with next 1, 2, 3, 4, 5 month maturity have a strong predictive power to the change of frozen shrimp spot and the change of frozen shrimp spot also have a predictive power to the change of frozen shrimp with next 1, 2, 3 month maturity. But, the explanatory power of the frozen shrimp futures is relatively greater than that of frozen shrimp spot.

  • 주식옵션(stock options)에 대한 연구에 비교하여 상품 및 퓨처 옵션(commodity & futures options)에 대한 연구는 선진국에서도 지금 한참 연구를 하고 있는 단계에 있다. 우리나라에서도 이 분야에 대한 이론을 바탕으로 하는 제도를 곧 도입하려는 준비를 하고 있다. 본 연구는 블랙의 '블랙의 컴모디티 옵션의 가격모형(Black commodity option pricing model)'을 이용하여 재무성 장기채권의 퓨처의 균형가격을 예측하는데 있다. 이 블랙모형의 적용가능성을 검증해 본 것이다. 실제퓨처가격(observed futures prices)과는 달리 재무성 장기채권 퓨처 옵션에서의 묵시적 퓨처가격(futures prices implicit)은 시장효율성(market efficiencies)의 전제하에 성립되거나, 아니면 옵션가격모형을 사용하여서는 아니되거나 둘 중의 하나이거나 둘 다 섞이거나 일 것이다. 본 실증적인 연구, 즉 묵시적인 표준편차(implied standard deviations)를 사이멀테니어스(simultaneously)하게 계산한 묵시적인 퓨처가격(implied futures prices)을 사용한 실증적인 연구는 옵션모델에 의하여 퓨처가격을 계산하는 데에 문제가 있음을 발견하였다. 그 이유는 옵션가격결정모형을 이용하여 계산한 재무성 장기채권의 퓨쳐가격은 재무성 장기채권의 미래가격변동의 방향을 제시하는 지표로써 사용할 수 없기 때문일 것이다. 우리나라에서도 이 분야에 대한 이론과 제도를 곧 도입하는 입장에서 선행되는 문헌이 될 것이다.
