  • This study conducted a comparative analysis by period and route through a variation allocation analysis with domestic container ports to analyze the change structure of container volume at Gwangyang Port. As a result of analysis of the absolute volume of container traffic at Gwangyang Port, the period and routes that showed the highest growth values by period and route were Europe, North America, Middle East, and South America in 2001-2007. It was followed by Southeast Asia, Oceania, Far East Asia, Europe, and Japan during the 2008-2012 period. Among the sections from 2018 to 2022, there are Oceania and Southwest Asia. In order to secure container shipments at Gwangyang Port in the future, it is essential to secure routes in Europe, the Americas, and Africa, and it is necessary to secure port competitiveness through improved management and service of container terminal operators

  • We evaluate two main rationales of massive policy intervention of Lee Administration in the Korean transportation fuel market: high market share of domestic refineries, perceived by the Administration as the result of high market concentration, and asymmetry in price adjustment, perceived as the result of collusion. Domestic refineries, huge in capacity and located at seaports, maintain international competitiveness in price. Considering market openness offering preferential treatment to importers, they set domestic prices competitively on the basis of MOPS prices. Yet, the price competitiveness of domestic refineries is so high that they are able to sustain high market share. We confirm that the Korean before-tax consumer prices of gasoline and diesel are lower than Japan's and the weighted averages of 27 EU countries by as much as 159KRW and 21KRW per liter in the case of gasoline and 170KRW and 63KRW in the case of diesel. Price asymmetry is caused by diverse economic and managerial reasons and, as FTC (2005) states, price asymmetry does not immediately imply exercise of market power or collusion. We analyzed price asymmetry in Korea, Japan and 14 EU countries, and found asymmetry in Korea and 11 EU countries in the case of gasoline and in Korea and 8 EU countries in the case of diesel.

  • The aim of the study is to examine the factors affecting publicness and efficiency of the regional public hospitals and specify their relationship, thereby drawing out the policy implications for further improvement of regional hospital management. The analytical results showed the followings. First, there were statistically significant mean differences between the above-the-mean group and the below-the-mean group in terms of the internal and external environmental factors and intensity of competition. Second, When the hospitals were divided into two groups based on the mean value of efficiency, the ratio of material costs, of operational costs, and of doctors, and GRDP per capita of the above-the-mean group and the below-the-mean group showed the significant mean differences. Finally, among the variables of publicness, the ratio of medical aid patients and the number of deliveries had the negative relationships with efficiency whereas the medical costs of medical aid recipients had a positive relationship. The general argument that the government should enlarge its support for the regional hospitals' publicness needs to be specified in terms of the particular components of publicness based on this study. Also, to determine the extent of government support, the further research on the external environmental factors that cannot be controlled by the hospitals, for instance, intensity of competition, GRDP per capita, and fiscal self-reliance, should be encouraged.

  • Korea and China have maintained sea routes between two nations through the shipping conference which was established in May 1993. Due to this effort, the market of Korea-China car ferry on Yellow sea makes growth year by year. The car ferry business has shown fierce competition because it has huge impacts on regional and national level economy. In this respect, the aim of this research is to analyze the structural analysis for ports of Korea-China car ferry using Shift Effect(SE) method. As a results, passengers and cargo volumes of Incheon port continuously transfer to Pyeontaek and Gunsan port. Moreover, absolute growth rate of Incheon port do not reach the potential growth rate. The competitiveness power of Incheon port has lower position compared to Pyeontaek and Gunsan port. The cargo volumes of ports located on western coast of Korea have increased recently, however, passengers and cargo volumes of Incheon port have shown lower increasing rate compared to average of Korean western coast ports. For Incheon port, high value added cargoes which give large profit on port side, have to be attracted. Moreover, Incheon port has to become a specialized port.

  • Clamp resist dyeing is a resist dyeing technique in which a fabric is sandwiched between two or more pieces of woodcarving and then a pattern is expressed by dyeing. Records from nine years of King Heungdeok's reign during the Unified Silla dynasty show that the use of the clamp resist dyeing technique was banned for different garments. This was only for garments of YOOKDUPUMNYEO (六頭品女) or OHDUPUMNYEO (五頭品女). Given this, it can be assumed that clamp resisted fabrics were widely used, and the technique had been established during the Unified Silla dynasty or before. However, only the term can be found in the records. Neither its definition nor how this technique was used is explained. Also, it is difficult to assume the types and features of clamp resist dyeing due to a lack of materials. A small number of relics from the Goryeo dynasty still remain, though. Craft techniques have developed through international exchanges and have changed according to respective nations' circumstances including politics, economics, society, and culture. Hence, this research analyzed documents and relics from China and Japan, two countries neighboring the Republic of Korea, and studied the different types and features of clamp resist dyeing techniques. Clamp resist dyeing techniques were divided into monochromatic or multichromatic according to the number of colors that represented patterns, rather than according to the respective nations' features. They were also classified into mono, bilateral symmetry, or vertical-bilateral symmetry according to the structure of the patterns. Through the study of examples of inherited or reproduced dyeing techniques in China and Japan, it was confirmed that different engraving techniques, including relief, openwork, intaglio fit for the feature of a pattern and the number of colors, were applied in order to vividly represent patterns on fabric. Using small flower pattern clamp resist dyed fine tabby in Amitabha of 1302, the only relic showing its patterns and colors in Korea, as the experiment subject, this research successfully reproduced a clamp resist dyeing technique through a successful experiment based on the basic materials from the dyeing technique case study. Due to the significance of the experiment on a clamp resist dyeing technique that stopped its transmission and shows the features of the technique, this study is expected to be a basic resource that can be used for future reproductions of multichromatic clamp resist dyeing techniques. Also, it is expected to be helpful in widening and recreating the world of Korean pattern dyeing with modern dyeing techniques.
