The purpose of this paper is to show the empirical measurement way for predicting the seaport efficiency by using SBM with Wilcoxson signed-rank test under CRS(constant returns to scale) condition for 20 Korean ports during 1994-2003 for 2 inputs(birthing capacity, cargo handling capacity) and 3 outputs(Export and Import Quantity, Number of Ship Calls, Port Revenue). The main empirical results of this paper are as follows. First, forecasting data have well reflected the real data according to the Wilcoxon signed rank test, because p values have exceeded the 0.05 significance level. Second, SBM has shown the effectiveness for predicting the ports efficiency even though the predicting powers are different according to the levels of p values. The policy implication to the Korean seaports and planner is that Korean seaports should introduce the new methods like SBM method with Wilcoxon signed rank test for predicting the port performance and enhancing the efficiency.

Gasification technology is one of the representative next-generation fossil fuel utilization technologies, converting low grade fossil fuels such as coal, heavy residue oil, pet-coke into highly clean and efficient energy sources. Accordingly, related market demand for gasification technology is ever increasing steadily and rapidly. A few years ago, conventional pulverized coal utilization technology had an edge over the gasification technology but the most significant technical barrier of limited capacity and availability has been largely overcome nowadays. Futhermore, it will be more competitive in the future with the advancement of related technologies such as gas turbine, ion transfer membrane and so on. China has recently completed a commercialization-capable large-scale coal gasification technology for its domestic market expansion and foreign export, rapidly becoming a newcomer in the field and competing with existing US and EU technical leadership at comparable terms. Techno-economic aspect deserves intensive attention and steady R&D efforts need to continue in organized, considering that gasification technology is quite attractive combined with $CO_2$ capture process and coal to SNG plant is economically viable in Korea where natural gas is very expensive. In the present paper, recent technology development and commercialization trend of many leading companies with coal gasification expertise have been reviewed with significant portion of literature cited from the recently held '2014 Gasification Technology Conference'.

Recently, it is expected to significantly increase the defense budget by acquiring large-scale weapons systems to enhance defensive capabilities. In order to secure funds needed to acquire such weapons systems, it is necessary to improve the efficiency of the defense budget. In addition, interest in economic factors affecting the domestic economy such as export opportunities and employment creation are increasing, as well as budget reduction of the defense acquisition business. In order to respond to these demands, this study conducted cost- benefit analysis and examined economic ripple effects in the implementation of defense procurement projects. However, research on economic analysis methodology considering characteristics of defense acquisition projects is still in its early stage. This study proposes a methodology to analyze the economic feasibility of defense acquisition projects and conducted a case study on the economic feasibility of the ${\bigcirc}{\bigcirc}$ guided missile project which is being prepared against local provocation. The proposed economic analysis method provides the cost-effectiveness analysis that has been performed in many weapon system acquisition projects in connection with the more general cost-benefit analysis method. This study contributes to the establishment of an improved theoretical methodology for weapon system acquisition projects.

China has become the group of two (G2) in almost fields including the scientific technology following the economic growth and joining the WTO in 2001. The main reason is that the government had strong intention for the industrialization of the scientific technology and connected the scientific technology and the economy. Typically, for analyzing the cause of the meteoric rise of China, the competitiveness of the scientific technology was analyzed by the entire score of the nation. However, in the case of China, there are differences in the pattern of the development between the eastern, central, and western province. Also, the industrialization and the competitiveness of the scientific technology are difference because each province established the decentralization of power. Therefore, it is more meaningful to analyze the main factors of Chinese economic growth on a province unit. In this study, therefore, we analyzed the competitive of R&D in China by 124 indexes in 31 areas. The data was analyzed by Partial least squares regression analysis. In conclusion, the scale of the area and the ability of R&D of the company are very important factors for total amount of production in the area. And the journals, patents, the transfer of technical know-how and the investment of R&D are main factors of the amount of export on the high-tech product. According to these results, the factors which make the difference in the industrialization and the competitiveness of the scientific technology in China were analyzed. Finally, it will be helpful to establish the policy for the development of the industrialization and the scientific technology in Korea.

Port Gyeongin was developed as a multi-functional port equipped with container and general port facilities and could be linked with nearby tourist attractions. However, it has experienced difficulties from the limitation of being a small port, duplicating functions, and lacking an interlink with nearby ports. Nonetheless, resident companies that need logistics facilities in Port Gyeongin or nearby ports process specific import and export goods such as wood, steel, and industrial products through Port Gyeongin because of the characteristics of the port. From this perspective, it is critical to establish a measure to promote Port Gyeongin through utility analysis of the stakeholders in Port Gyeongin. In this regard, the purpose of this study was to analyze the preference of stakeholders in Port Gyeongin using conjoint analysis and propose a difference in the preference of the stakeholders. Study results show that the terminal group, shippers, and tenant companies considered the berthing capacity, incentive scale, and port logistics cost as the most critical matters, respectively. The stakeholders in Port Gyeongin should recognize the difference in critical matters, and be equipped with shipper discovery and institutional arrangement according to the characteristics of Port Gyeongin such as cooperation with related institutions and inter-collaboration between operating companies to promote Port Gyeongin.

The purpose of this paper is to show the empirical measurement way for predicting the seaport efficiency by using Super SBM(Slack-based Measure) with Wilcoxson signed-rank test under CRS(constant returns to scale) condition for 20 Korean ports during 11 years(1997-2007) for 3 inputs(port investment amount, birthing capacity, and cargo handling capacity) and 5 outputs(Export and Import Quantity, Number of Ship Calls, Port Revenue, Customer Satisfaction Point for Port Service and Container Cargo Throughput). The main empirical results of this paper are as follows. First, Super SBM model has well reflected the real data according to the Wilcoxon signed rank test, because p values have exceeded the significance level. Second,Super-SBM has shown about 87% of predicting ratio for the ports efficiency and the optimal size of investment in domestic seaport. The policy implication to the Korean seaports and planner is that Korean seaports should introduce the new methods like Super-SBM method with Wilcoxon signed rank test for predicting the efficiency of port performance and the optimal size of investment as indicated by Panayides et al.(2009, pp.203-204).

The purpose of this study is to examine the legal standards of agreements on the origin of liability and the relevant laws in Korea, to suggest implications for custom authorities and traders wishing to benefit from preferential tariff via FTA, citing the excluded cases of related FTA preferences (court cases and administrative judgments). In order to examine the provisions related to supporting evidence of the origin of liability in FTA, we examined FTAs agreed between Korea and EU, EFTA, ASEAN, U.S., and India relevant to FTA Special Customs Act, court cases and administrative judgements. If verifying the origin to protect the fair trade order impedes to promote utilizing FTA, solutions will need to be suggested. If FTA preference is exempted due to verifying the origin by the import customs authorities, the importer shall pay the income tax calculated in accordance with the general tax rate. This is because the certificate of origin confirmed during verification process is different from the actual origin. In most agreements, the exporter (the producer) shall issue the certificate of origin and since the importer has no other option than obtaining the certificate of origin from the exporter, it may face consequences such as declined credibility from the custom authorities in addition to being disqualified for FTA preferential, if the certificate of origin received from the exporter has flaws. On the other hand, the exporter cannot help but being punished by the customs authorities due to issuing defective origin certificates, but it doesn't have conventionary liabilities for damages incurred to the importer. As a result, importers are forced to pursue legal proceedings to claim damages to exporters or to give up FTA preference. As FTA is increasingly utilized, the number and amount of origin verification in Korea has continuously been increasing while administrative judgements indicates other FTA exporters doesn't seem to gain any support in utilizing FTA like Korea does. It has been 8 years since full-scale supports in FTA launched and now is the time to introduce more efficient and intensive FTA support system In this regard, it is desirable to conduct comprehensive verification on export Next, an institutions that assures FTA-based exports should be established in order to compensate the importer's damages that may occur from disqualified certificate of origin issued by the exporter.

All the major ports around the world as well as those in Korea have been exploring their own strategies to survive rapidly changing marine transport environment worldwide. In particular, Busan New Port under development still fails to meet expected logistical traffic, although it operates 6 berths. That is why it is necessary to point out current challenges in logistical strategy of Busan New Port for fully dealing with logistical traffic. Therefore, this study can propose the following ways to facilitate logistical traffic of Busan New Port. First, it is necessary to apply equal tariff to incentives given to shipping agent under the associations between existing harbors and Busan New Port. Second, it is required to increase governmental subsidy for truck freight transport. Third, it is demanded to seek possible ways to transport export and import freight and thereby create independent logistical traffic. Fourth, it is necessary to contact shipping agents residing in new ports and establish a logistical program for shipping freights via Europe, Middle East and Russia as well as those by way of North America, Japan, Korea and China, ultimately making sustainable marketing strategy to create a series of continuous transshipment freight, not temporary one. Finally, it is advisable to operate networked logistical programs with small- or medium-sized overseas shipping agents in business association with large-scale overseas shipping agents.

This paper demonstrates the design and development of asset management systems suitable for the universities full of very various kind of assets. Universities consists of many departments, which have a multiplicity of many experimental. It is very difficult to record and manage assets with hands. In addition, the equipments are moving freely from one lab to another inside the school, which means it is tough to find the location of the assets and so some stuffs that are given lack attention are likely to disappear. So, these things occurring frequently in the university asset management environment should be considered in the design and embodiment of the asset management system. In the proposed system, location recognition of the assets is realized based on a route tracking method, so it is possible to detect the loss of the high priced assets and entrance, export, and lending of them are controlled efficiently. The system is likely to reduce the load of a manager responsible for asset management, because configured to decrease interventions of the manager in overall asset management process. Especially, the proposed system and implementation method will be suitable for small and medium-scale asset management, path tracking, history management.

South Korea has achieved impressive economic growth relatively quickly by focusing on export-driven policies and economies of scale in the process of industrialization. As the country's economic development policy focused on large corporations, however, a power and wealth imbalance developed between SMEs and large corporations. The purpose of this study is to clarify this issue academically and more clearly through theoretical studies and empirical analysis in order to resolve these imbalances and improve the positive relationship between SMEs and large corporations. To this end, a survey was conducted from December 17, 2018 to January 28, 2019, and a total of 378 questionnaires collected from corporate workers were used for the final analysis. The hypotheses confirmed by the study results were as following. First, the factors directly affecting the competitor's orientation were the trust, entrepreneurship, and innovation capability of the entrepreneurial characteristics. Second, when the characteristics of the company were examined from the perspective of cooperative performance, only the innovation capacity factor had a positive effect. Third, the competitor orientation showed a positive effect on cooperative performance. Fourth, competitor orientation had a statistically significant mediating effect on the relationship between trust, entrepreneurship, innovation capability, and cooperative performance.
