Domestic urban railway are operated by urban railway operating public enterprises, which are owned by the 6 major metropolitan local governments and private operating companies, which are established under the Private Investment Act. Among urban railway operating companies, several public enterprises that operate urban railways with many experience, performance, human resources, and public nature are making efforts to promote overseas business. Therefore, this study examines the outlook for railway and urban railway overseas business, and provides implications for the overseas business approach of domestic urban railway operating public enterprises through data research and comparative analysis on the overseas business approaches and overseas business characteristics of domestic and foreign urban railway operating public enterprises. The results were derived and suggestions for the direction of overseas business were presented. I expect that suggestions will serve as a reference for domestic urban railway operators to promote overseas projects with preparation, implementation plan and direction.

With the huge concerns on the inefficiency of public enterprises, particularly a significant amount of debt, an increasing number of studies have been carried out to analyze the levels of inefficiency and investigate the causes of that inefficiency. However, very limited range of analytical methodologies have been used in the efficiency analysis and moreover, the effects of external factors have been little addressed. This study explores the efficiency of urban railway corporations in Korea by utilizing a method of stochastic frontier analysis (SFA). In particular, the potential effects of external factors including residential and floating populations of a station were statistically analyzed. A total of seven Korean urban railway corporations were selected to compare each other in terms of operational efficiency. The results present three important findings. First, the Cobb-Douglas model was found to be more valid for SFA compared to the Translog model. Second, the efficiencies of urban railway corporations in Seoul and Busan are relatively high whereas those of Daejeon and Gwangju are very low in efficiency in the area of sales revenue. In an aspect of number of transport of passengers, Gwangju Metro also showed the lowest efficiency. Third, the external factors are significantly associated with the efficiency, indicating that the efficiencies of Daejeon Metro and Gwangju Metro would increase while the efficiency of Seoul Metro would decreases when the external variables are excluded in the efficiency analysis. The results provide several meaningful implications for managers of the urban railway corporations as well as policy makers who are attempting to resolve the inefficiency problems of public enterprises.

The main purpose of this study is to highlight the effects of the Bolman and Deal's multi-frame leadership on the several dependent variables such as job satisfaction, respect from subordinates, effective goal attainment, promotion speed, and recognition as more a leader than a manager. To attain this purpose, 488 questionnaires verified to be free from flaws were processed through SPSS 14 Windows. The major finding was that versatile and adroit use of multiple frames can contribute to the effectiveness and success of the leader. That is, the multi-frame leadership had strong relationships with dependent variables such as trust and respects from subordinates, effective attainment of unit's goal, job satisfaction, recognition as more a real leader than as a manager, and promotion speed of boss. When we consider the ever-increasing environmental complexity surrounding every organization and the growing levels of needs of employees, the use of multi-frame leadership is not an 'ought' but a 'must' for all the people who aspire to become effective and successful leaders.

Regarding the small- and medium-sized enterprises in Korea that manufacture the railway vehicle parts, there are over 250 related companies. And they have been surviving in the form of producing and delivering the parts of the railway vehicles by importing the technologies and the products of the foreign countries rather than possessing their own technological abilities. Due to this, regarding the industry of the core components of the railroads, the dependence on the overseas has been high. As such, although, for supporting the small- and medium-sized enterprises that manufacture the railway vehicle parts, the government has been strengthening the diverse policy supports, it is a fact that the effectiveness of the support is not high. And, in order to effectively support these, there is a need to understand clearly and definitely what the important promotion factors are in the process of the technology commercialization. Accordingly, through the precedent researches regarding the factors that promote the technology commercializations of the small- and medium-sized enterprises that manufacture the railway vehicle parts, this research had extracted 10 main items. And the level of the importance of these indices was analyzed by using the AHP (Analytic Hierarchy Process). As a result of the AHP analysis, the factors within a corporation appeared to be the most important factor. And, as for the lower-ranking item, the commercialization capability was analyzed to be the most important item. It is highly expected that the contents and the results of this research will be usefully used when formulating the planning of the support program and the support policy for the technology commercializations by the public research organizations and the railroad management organization, which is an organization that supports the small- and medium-sized enterprises that manufacture the railway vehicle parts.

The main purpose of this study is to depict the causal relationship among Market Orientation(MO), Marketing Capabilities(MC), and Organizational Performance(OP) with the moderating effect of Environmental Turbulence(ET), especially comparatively highlighting the differences between Korail and Subway firms. Findings show that there partly existed significant interactions effects between ET and MO in case of subway firms, whereas Korail did not reveal any significant results. When considering the strong relationship between MO and MC shown in the subway firms' case, it can be inferred that subway firms continuously have attempted to adapt to the external environment facing them more flexibly and actively over their counterpart, by which the degree of their MC became positively enhanced over Korail. These results give us some implication that MO should be internalized and also MC should get a higher consideration than ever throughout the railway public enterprises in order to strengthen their performance.

The purpose of this article is to highlight the relationships among market orientation, environmental turbulence, marketing capabilities, and organizational performance in railway industry(616 participants). Major findings are: 1) market orientation showed a significant effect on marketing capabilities, and organizational performance, 2) environmental turbulence functioned as a moderator not to organizational performance, but to marketing capabilities, 3) and marketing capabilities showed a strong effect on organizational performance. These findings imply that market orientation, as well as marketing capabilities, are so essential for creating a supreme performance in the railway industry.

This study analyzed the efficiency change and the factors affecting productivity change for the six railway operation corporations that are local public enterprises; study was performed with the DEA-CCR Model and Malmquist Productivity Index, using data collected from 2010 to 2014. Since it was not feasible to collect data on the operating expenses and the number of employees of each of the lines, the efficiencies of each operation corporation were analyzed by integrating the operation corporations, and the Malmquist Productivity Index was used to investigate the trend of the periodical productivity change. Average efficiency for urban railway operation corporations was found to be higher in the case of the bigger corporations. In 2014, the Seoul Metro and the Daejeon Metropolitan Express Transit Corporations were analyzed and found to be the most efficient operation corporations. The Malmquist Productivity Index was used to determine the periodical change; the average MPI was 1.06, with a continuous increase of productivity. The analysis showed that changes of technology were generally more obvious than change of technology efficiency for all six operation corporations.

As IT is also recognized as assets, IT assets management system is trying to introduce for the management and operation in domestic enterprises and public institutions. The general assets management system was introduced in domestic companies, but because it managed mainly the only simple information about the assets, there were a lot of operational difficulties of the assets. In order to operate effectively the IT assets used in special business such as bank, prosecutors, railway, etc the classification system of IT assets based on the EA was needed first of all. Accordingly, in this paper, we classified IT assets systematically according to the EA meta model Application Guide V1.4 in consideration of the characteristics about the IT asset business for A public institution, and performed to improve the operating costs and efficiency by implementing a web-based IT assets management system for this public institution.
