The Korean government has tried to increase the total national R&D investment and, to streamline acts and regulations concerning national R&D activities. Korea's total R&D expenditure in the field of S&T for the year 2006 amounted to about 27.3 trillion won including government R&D of 8.9trillion won. The Korean government enacted several pieces of legislation concerning S&T: the "Technology Transfer Promotion Act (1999)" ; the "Framework Act on Science and Technology (2000)", and the "Presidential Regulation for Managing the Government R&D Programs (2001)." With these efforts the capacity of Korea S&T has made great strides recently. But for years Korea has run a severe deficit of technology trade. The Korea's balance ratio of technology trade is 0.36 (export/import). It means that Korean industry excessively depends on foreign resource in introducing new technologies. The Korean government has put a lot of effort into promoting the commercialization of technologies developed in universities. The public technology transfer policy of the government has improved the infrastructure of technology transfer and commercialization. However, the government has realized that these policies have not been as effective as they were anticipated. In spite of these various efforts, the technologies obtained from the government R&D Programs have not been transferred to the Korean industry properly. Only 13.6% of technologies developed in universities for the year 2005 were transferred to industry. The academic royalty revenues for the year was 0.15% of their total R&D expenditure It shows only a twentieth of the percentage of royalty revenues for the American universities. The reasons of poor commercialization of academic technologies are intermingled with imperfection of technology transfer system, lack of licensing experience, immaturity of socio-economic circumstance and inadequacy of legal system and government policy. In this study we analyzed the problems of legal system and policy in licensing of government R&D outputs and suggested proper alternatives.
The aim of this study is to analyze the container terminal operation by considering the key factors that fluctuates the container traffic volume using the System Dynamics (SD) method. The target area of this study is the 'A' container terminal which is located in the Port of Incheon and the simulation period is from 2004 to 2020. As evaluation indexes for container terminal operation, three factors such as 'total sales', 'operating ratio of C/Y' and 'operating ratio of G/C' are selected, and as for the key factors of fluctuating container traffic volume, 'variation ratio of world trade', 'variation ratio of trade among three countries in North-East Asia' and 'variation ratio of won-dollar rate are used. As of 2020, the result of this study is that import-export container traffic volume increases almost 880,000TEU and total sales and operating ratio of G/C each reach 7.1 bilion won and 65 percent. No changes however in loadage and operating ratio of C/Y in 'A' container terminal are indicated. The reason is that capability of C/Y is exceeded. Therefore this study suggest that decision-makers of 'A' container terminal realize the importance of additional space of C/Y.

The finite element method (FEM) has been used for various fields like mathematics and engineering. However, the FEM has a difficulty in describing the geometric shape exactly due to its property of piecewise linear discretization. Recently, however, a so-called isogeometric analysis method that uses the non-uniform rational B-spline(NURBS) basis function has been developed. The NURBS can be used to describe the geometry exactly and play a role of basis functions for the response analysis. Nevertheless, constructing the NURBS basis functions in analysis is as costly as a meshing process in the FEM. Since the isogeometric method shares geometric data with CAD, it is possible to intactly import the model data from commercial CAD tools. In this paper, we use the Rhinoceros 3D software to create CAD models and export in the form of STEP file. The information of knot vectors and control points in the NURBS is utilized in the isogeometric analysis. Through some numerical examples, the accuracy of isogeometric method is compared with that of FEM. Also, the efficiency of the isogeometric method that includes the CAD and CAE in a unified framework is verified.

This paper aims to investigate the relations among the entrepreneurship, SWOT factors, and performance in Korean hidden champion firms. 112 potential Korean hidden champions were drawn at random from the hidden champion candidates of Export-Import Bank of Korea. For analyzing the relationship of them, the entrepreneurship factors categorized with organizational risk taking, innovativeness, and proactiveness from previous researches(Khandwalla, 1977; Miller, 1983; Miller & Friesen, 1978, 1982). Also, four SWOT factors classified into strength, weakness, opportunities, and threat by confirmatory factor analysis. As a result, we found some statistically significant effects between the SWOT factors and entrepreneurship factors, and they sequentially affects to performance. That is, as a presented with previous research, there is verified that entrepreneurship is caused by organizational risk taking, innovativeness, and proactiveness. Also, SWOT factors significantly affect to business performance. Some guidelines for practicing potential Korea hidden champions as a result of this would include; first of all, it is important to support the potential hidden champions consulting approach in global perspectives; secondly, effective governmental support programs for hidden champions should be developed for positive impacts of according to these results.
Polymerase chain reaction (PCR) was used to detect cattle material from processed meat products. Seventy-eight different commercial processed meat products were purchased from several big food marts. Among them, 17 products contained cattle material (10 samples contained only cattle, 5 samples mixed with cattle and porcine, 2 samples mixed with cattle, porcine and chicken). The genomic DNA was extracted directly from the processed meat products, and strain-specific primer targeting the 16S ribosomal RNA mitochondrial gene was used. All PCR products were cloned into the pGEM-T easy vector and sequenced. Consequently, the PCR products were amplified from 10 processed meat products, which contained only cattle material in our conditions. Furthermore, PCR reactions showed the same results at mixed samples. The DNA sequence obtained from pGEM-T easy/PCR products showed more than 95% identity with Bos taurus 16S rRNA gene using homology analysis. In conclusion, we suggest that the method using PCR, as performed in this study, could be useful in detecting cattle material in processed meat products. Moreover, our system could be applicable in inspection procedures to improve the verification of correct labeling for import and export processed meat products.
This study aims to analyze the effects of service quality offered by automotive Ro-Ro terminal operators on customer satisfaction and loyalty. The results of the research can be used to understand how to enhance the service level in order to manage competitiveness of the terminal operators, finally resulting in global competitiveness of the automobile industry of Korea in both exports and imports. We carried out a survey on two groups: shippers (customers) and providers (related terminal operators and stakeholders). To identify and classify the factors into groups, we conducted Exploratory Factors Analysis (EFA) and Confirmatory Factor Analysis (CFA), which showed construct validity and convergent validity. We also calculated Cronbach's alpha for reliability. Five factor groups were identified: tangibles, reliability, responsiveness, assurance, and empathy. We found that empathy is the most influential factor group among the five groups, and that the other groups too exhibited similar effects. Based on the results of the survey and analyses, we can conclude that empathy is most important in automotive Ro-Ro terminals. In particular, specialties, training, experiences, and loyalty of employees are crucial factors because automotive Ro-Ro terminals significantly rely on work forces, differently from other bulk terminals and container terminals. Flexible working hours and fringe benefits for work forces can increase empathy, finally resulting in productivity and efficiency. Next, well-designed work schedules are followed, based on visibility through logistics and SCM activities in automobile export and import processes with information and communication networks.
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.

Recently, with the development of wireless communications and mobile computing, interest about mobile computing is rising. Mobile computing can be regarded as an environment where a user carries mobile devices, such as a PDA or a notebook, and shares resources with a server computer via wireless communications. A mobile database refers to a database which is used in these mobile devices. The mobile database can be used in the fields of insurance business, banking business, medical treatment, and so on. Especially, LBS(Location Based Service) which utilizes location information of users becomes an essential field of mobile computing. In order to support LBS in the mobile environment, there must be an Embedded Spatial MMDBMS(Main-Memory Database Management System) that can efficiently manage large spatial data in spatial mobile devices. Therefore, in this paper, we designed and implemented the Embedded Spatial MMDBMS, extended from the HSQLDB which is an existing MMDBMS for PC, to manage spatial data efficiently in spatial mobile devices. The Embedded Spatial MMDBMS adopted the spatial data model proposed by ISO(International Organization for Standardization), provided the arithmetic coding method that is suitable for spatial data, and supported the efficient spatial index which uses the MBR compression and hashing method suitable for spatial mobile devices. In addition, the system offered the spatial data display capability in low-performance processors of spatial mobile devices and supported the data caching and synchronization capability for performance improvement of spatial data import/export between the Embedded Spatial MMDBMS and the GIS server.
Food irradiation is an emerging technology which offers many advantages such as reduction of microorganisms, extension of shelf-life of foods, reduction in the use of post-harvest chemicals, and destruction of insects and parasites. The commercial utilization of food irradiation, however, has been restricted because of the uncertainty of consumers' responses to it. Because success of food irradiation in the marketplace will depend upon their acceptability by consumers, this study focused on the consumers' perception and acceptance toward food irradiation in order to get basic data for commercial utilization of food irradiation and give information to consumers to help rational consumption behavior. The survey with 411 respondents living in Youngnam area was conducted during the spring of 1997 by the questionnaires. The results and implications from this study are as follows. First, consumers' knowledge about food irradiation is scanty. Two-thirds of respondents in the survey had not heard of irradiated foods and many people confused irradiation with radioactivity. In the willingness to accept food irradiation, one-third of respondents showed a wait-and-see attitude. This result indicated consumers had insufficient information about the irradiation process and nationwide education of food irradiation technology should be undertaken. Second, although the purchase and use of food are very important consumption behaviors, consumer education by mass communication has been rarely done. For the successful commercialization of food irradiation, the information provision by mass communication for the consumers should be made. Third, consumers generally worried about residual pesticide and intended to purchase irradiated foods if radioactivity was not retained in the foods. Therefore, food irradiation could be an alternative method to the use of pesticide Fourth, consumers pointed out that they wanted to extend shelf-life of milk and dairy foods, fish and seafood and to irradiate these foods. Therefore, research for the safety of irradiated foods should be continually conducted. finally, labeling for irradiated foods is needed to provide the information and to further increase public understanding. Especially, the labeling should show the definite reason why irradiation is being used. In conclusion, recently, under the circumstances that the commercial utilization of food irradiation and irradiation for the import and export products have been increased in many countries, many efforts are needed to improve the quality of irradiated foods, and prove the safety of them in Korea. In addition, consumer education for food irradiation should be given to help consumers to make decision for food purchase and use.
The Government of Korea has always focused on developing and maintaining a surplus on the balance of payments as a successful trade policy. The focus should now be on spatial information hiding, revealing patterns in trade activities that enable viewing trade in a more sophisticated manner. This study utilizes trade statistical data such as the United States-South Korea imports and exports from 2003 to 2015 officially released by the two countries. It allows us to analyze and extract the spatial information pertaining to the origin, transit, and destination. First, in the case of export data to the United States, the origin of the trade goods has expanded and decentralized from the metropolitan area. With regard to transit, in 2003, most of the exported goods were shipped by ocean vessels and arrived at the ports on the western coast of the United States. However, trade patterns have changed over the 12-year period and now more of that trade has moved to the southern ports of the United States. In terms of destination, California and Texas were importing goods from South Korea. With the development of the automotive industry in Georgia and Alabama, these two states also imported huge volumes of automobile parts. Second, in case of import data, most imported goods from the United States originated from California and Texas. In this case, 40% of goods were shipped by air freight and arrived at the Incheon-Seoul International Airport; most ocean freight was handled at the Port of Busan. The purpose of this study is to decompose the spatial information from the trade statistics data between Korea and the United States and to depict visualized bilateral trade structure by origin, transit, and destination.
