Purpose - Using unexpected changes in geopolitical tensions on the Korean peninsula as a quasi-natural experimental setting, we examine whether and how geopolitical risks travel across borders through firm-level imports and exports linkages. We also test whether the effects are driven by either imports or exports and assess whether firms can effectively hedge themselves against geopolitical risks. Design/methodology - We focus on a series of unanticipated geopolitical events taken place in Korea in 2018. Making use of the shocks to geopolitical climate, we identify five milestone events toward peace talks. We employ the event studies methodology. We examine heterogenous firm-level stock price reactions around key event dates depending on firms' exposure to geopolitical risks. As a measure of firms' exposure to geopolitical risks in Korea, we utilize a text-based measure of firm-level trade links. When a firm announces and discusses its purchase of inputs from Korea or sales of outputs to Korea in their annual disclosure filings, we define a firm to have a trade relationship with Korea and have exposure to Korean geopolitical risks. Similarly, we use a measure of a firm's hedging policies based on a firm's textual mention of the use of foreign exchange derivatives in their annual disclosure. Findings - We find that U.S. firms that have direct trade links to Korea gained significantly more value when the intensity of geopolitical risks drops compared to firms without such trade links to Korea. The effects are pronounced for firms purchasing inputs from or selling outputs to Korea. We find that the effectiveness of foreign exchange hedging against geopolitical risks is limited. Originality/value - We document the international transmission of geopolitical uncertainty through trade linkages. Export links as well as import links serve as important nexus of transmission of geopolitical risks across borders. Hedging strategies involving foreign-exchanges derivatives do not seem to insulate firms again geopolitical risks. With the recent movements of localization and reshuffling of the global value chain, our results suggest a significant impact of geopolitical risks in Korea on the construction of the global value chain.

The purposes of this study was to exploit the differences on recognition for the service provided between salespeople and customers who have purchased fashion apparels and garments at the department stores, and to suggest the educational direction of salespeople in order to enhance competitiveness and to increase customers' satisfaction. Data were obtained from 297 apparel salespeople working at 6 department stores and 285 customers of department stores in Daegu. Statistics used for data analysis were frequency, mean, t-test, ANOVA, and regression analyses. The important factors which affected the purchase of fashion products, in order of importance, were information ability, credibility and service quality of salespeople. But the service quality recognized by customers was lower than that by salespeople. It can be said the salespeople have to make every effort that customers feel comfortable and certain for the service provided. There were significant difference on the service provided by salespeople, as well as service quality recognized by customers in accordance with gender, marital status, age, level of education, and annual fashion apparel expenses.

Swedish research in 2002 indicated that acrylamide formation was particularly associated with traditional high temperature cooking processes of certain carbohydrate-rich foods. Since the Swedish report, similar findings have been reported by researchers in numerous other countries. In 2003, three hundred and twenty seven domestic food products, selected on the basis of annual sales in Korea, were analyzed. The results were similar to those from other countries. In this study, the monitoring of acrylamide was expanded to include Korean traditional food products. Samples were purchased from local markets, prepared and then analyzed using LC/MS/MS methods. The categorized food products analyzed included cooked rices and porridges, soup products, fried products, boiled down products, seasoned products, roasted products and coffee. The acrylamide concentrations of the samples were $ND\~18ppb$ in cooked rices and porridges, $ND\~28ppb$ in soup products, $ND\~22ppb$ in fried products, $ND\~218ppb$ in boiled down products, <10ppb in seasoned and roasted products, and <10\~11ppb in brewed coffee and coffee drinks.

This study is aimed to estimate a dynamic productive efficiency by vessel of large purse seine fishery and analyze changes of them over times using a window/DEA method. In addition, based on estimation results, it aims to suggest production management implications for an viable development of fisheries. Results indicated that an annual efficiency change of large purse seine fishery was estimated at 0.77 for 2007~2008, 0.83 for 2008~2009, and 0.77 for 2009~2010, showing a decreasing trend. As returns on sales of vessels of large purse seine fishery showed a decreasing trend, the degree of efficiency of a vessel might be closely related to the fishing profitability. The Window/DEA method was used in this study to estimate the efficiencies of vessels for large purse seine fishery. This method is well known and widely used to analyze the dynamic efficiency and it can provide useful implications for management of input factors. As a limitation of this study, it was not able to provide detailed management ways to reduce inefficiencies. However, they can be investigated with data on managerial factor, human factor, distribution factors as a future study.
