The purpose of this paper is to show the brief empirical measurement using the cross-efficiency model and integer programming method for 13 Asia container seaports in 2009, 2010, and 2013 data for 3 inputs( depth, total area, and number of crane) and 1 output(TEU). After clustering using cross-efficiency model, efficiencies are increased in the Busan and Incheon ports. Results using integer programming method focused on the output(TEU) show that Busan port(Hongkong, Dubai, Ningbo, and Chingtao ports), Incheon port(Ningbo, Gwangyang, and Nagoya ports), and Gwangyang port(Nagoya, and Incheon ports) are clustered with the ports in the parentheses. After clustering, efficiencies are not definite in two ports and three ports clustering. The containerport policy planners should introduce and consider the cross-efficiency model and integer programming method when they measure the efficiency increasing plan for the main Korean containerports.

This article examines the relationship between supply chain integration and the factors of that, and its impacts on performance. A literature review is undertaken to drive the model and hypotheses, and operationalize the included constructs from supply chain articles related. Structural equation modeling is used to analysis the relationship between independent factor and dependent factor on survey data. Results of this study indicate that independent factors such as trust, information, dependence, engagement each positively influence supply chain integration at the significant level. And supply chain integration also positively influences supply chain performance. The results of this empirical study provide the based perceptions for third party logistics of supply chain manager. Limitations of this study only use perception data received from machine tool industry.

In regard to the comprehensive and efficient management and operation of the World Ethnic Food Theme Pavilion, this paper intends to propose methods for management and operation that ensure the efficient management of profit facilities, while maintaining the professionalism and minimization of management functions, the improved efficiency of facility management, and the public nature of the facilities. Further, this task aims to grope for methods for pursuing maximum effectiveness and efficiency with minimum manpower, while working out detailed management and operation plans in consideration of the economic feasibility, stability, continuity, efficiency, technical performance, and expertise of the World Ethnic Food Theme Pavilion, and maintaining the core functions of the World Ethnic Food Theme Pavilion.

The exchange rate pass-through is non-linear and asymmetric unlike the standard models. The asymmetric effects of exchange rate changes can be explained using the quantity constraint model and the market share model. To explain the non-linear effects the menu cost and switching cost in consumption were assumed. This study tests the asymmetry and non-linearity assumptions in the effects of exchange rate changes on the export prices of manufacturing goods. We estimated the export price as functions of the exchange rate with interactive dummy variables reflecting the various situations. The results suggest that especially asymmetries in exchange rate pass-through cannot be ignored. In the pre-crisis the price effect of won appreciation was greater than that of won depreciation as the quantity constraint model says, but after the crisis the result was reversed suggesting the market share model is appropriate.

The primary concern of this study is to investigate the relationship between savings and investment in Korea. In our research we employ causality and cointegration based tests. Engle-Granger 2 stage cointegration test shows significant. Additionally, we employ multi-cointegration tests to investigate deeper cointegration capturing cumulative current account properties. However, there is no relationships. We find the relationship from savings to investment through causality test. And Non-linearity test shows the existence of non-linearity. Thus we employ alternative method to examine the multi-cointegration, which as been proposed by Engsted et al.(1997), and reveal the relationships from savings to investment. The implication of these procedure implies it is necessary alternative theoretical and empirical specifications for savings and investment investigation in future researches.

Traditionally Korean Ginseng has been appraised as the best quality as a medicine for health. However the countries which drive export their other kind of Ginseng to the world becomes serious competitative factors in Ginseng Industry. That's why now it is needed to develop the Korean Ginseng industry competitiveness in exporting to the world. According to the statistics Korea's RCAx is very stable, other countries are fluctuated. But their competitiveness is low price even though their low quality. Otherwise Korean Ginseng export cannot have the barrier into the world market. From 2001 FTA with Chille made the beginning of the agribusiness export to the world. Especially along with the Hallal of the cultural side, this could be improved year by year. Here we can find very specific strategy in Korean Gingseng export and now, we are analysing the new strategy in this hard export situation. If there would be new strategy based upon Hallal and new market into middle east countries will bring new strategies in the Gingseng industry. In this thesis how to make strong in Ginseng export strategy and how to improve the export competitiveness is the main point of research.

Logistics is important to every country. China's logistics industry has developed with rapid speed and also has supported the fast pace of economic development. While there are many research studies on China's logistics, these only concentrate on partial topics and; minor issues such as the definition of the logistics industry, the significance of logistics development as well as the 3PL, 4PL of the logistics industry. To date, there is a lack of studies on the perspective of the logistics industry's macro-scopic and regional comparison and analysis. Thus, this paper focuses on this research gap. In this study, China's logistics industry is surveyed and analyzed macroscopically and locally. Using annual logistics data, the two-dimensional research contents are presented and integrated. Based on these integration, the development strategies of China's logistics are arranged with national, industrial and company dimension. With this regional analysis, development speed between 4 cities, ratio of 4 cities' logistics volume and China's logistics volume are presented and understood.

This paper presents results of a Zellner's SURE-regression analysis on empirical estimates of imported and domestic energy substitution in Korea Steel Industy. Theoretically it is clear that a distinction should be made between Morishima substitution elasticities and cross-price elasticities. The former represent purely technical substitution possibilities while the latter include an income effect and therefore represent economic substitution potential. I estimate a Zellner's SURE-regression model with separate coefficients for the Korean Steel industry. My findings suggest that primary model assumptions on returns to scale, technological change and separability of input factors matter for the outcome of a primary study. Aggregation of variables and the type of data used in empirical research are also relevant sources of systematic effect-size variation. Taking these factors into consideration, I compute ideal-typical elasticities for the energy demand. The resulting figures clearly show that substitution elasticities are substantially higher than cross price elasticities. Therefore, despite considerable technical opportunities for imported and domestic energy substitution, the cross price elasticities are not statistically different from zero.
