This paper investigates the management stability of KOSPI-listed energy public enterprises from the perspective of median voter theory. We analyze the profitability and stability of five energy public enterprises during the period 2011~2022, and conduct an empirical analysis to determine whether they are related to the preferences of median voters who can represent the general public. Our analysis of the profitability and stability of the energy public enterprises shows that the stability of their has been deteriorating in recent years. The results of the empirical analysis also show that the management stability of the energy public enterprises is related to the preference of median voter. Specifically, they indicate that when the median voter's income is smaller than the average income, the profitability of the utility decreases and the debt ratio increases. This paper suggests that from the median voter's point of view, excessive utility and energy bills may strengthen the incentives for governments and politicians to suppress rate increases, leading to lower profitability and higher debt for public enterprises.

This paper examines empirically whether information and communication technology(ICT) has improved total factor productivity at industry level in Korea, considering time lag between ICT capital accumulation and improvement of productivity. To evaluate if ICT is pervasive enough to raise productivity, ICT capital stock of Korea is compared with those of advanced economies. From the perspective of aggregate economy, the ICT capital in Korea has increased fast since the mid-1990s and became comparable with advanced economies. However it is mostly attributed to rapid growth of ICT-producing industries. In other industries, ICT capital are still less accumulated than advanced economies. Growth accounting results exhibit that the productivity has risen faster since 2000 in industries using ICT intensively, but looking into specific industries, it is not likely for ICT to be the main factor of productivity improvement except in business service industry. Regression results provide some evidence that ICT is useful in raising productivity only after considerable amount of time allowed. To fully exploit the positive effect of ICT on productivity, it may be necessary for the Korean economy to create institutional environment facilitating complementary innovations as well as ICT captial accumulation.

군 정비창과 방산업체 어느 곳에서 창정비를 하는 것이 효율적인지 판단은 군수지원체제의 효율성, 가동률 향상측면, 경제성 등을 종합적으로 분석하여 결정할 사항이나, 무기체계를 생산하고 정비설비와 기술인력을 확보한 방산업체에서 수행하는 것이 여러 측면에서 효과적이고 바람직할 것으로 판단된다. 외국의 창정비 정책도 자국 소요를 위주로 하는 국가는 생산업체에서 담당하고 있다. 방산업체가 창정비를 하게 되면 생산량 감소에 따른 가동률 높일 수 있고, 창정비 활동을 통하여 핵심 기술인력을 유지하고 성능개량을 통한 기술력도 향상시킬 수 있을 것이다.

Unlike the era of manufacturing-oriented industrial economy in the past, the era of service economy has characteristics intangible goods center, knowledge universalization, and expansion of needs, and many things that are of the economy are changing. In the past, the change in the environment was not fast, so even after analyzing the changed environment and deriving the talent needed for the company, it was possible to maintain a talent for the organization for a long time, so it is not proactive to build and apply talent. It became difficult to manage effectively. Therefore, in this paper, we conducted a normative study for deriving a desirable talent model rather than a descriptive human resource model. Human resources image suitable for the modern service economy era, the modern economic society and modern spirit were analyzed and reflected. The model in which the two opposing members of the organization, managers and employees, interact intensely and balance dialectically. A desirable talent in a modern organization must play the role of a manager, and the management and talent models in a modern organization can be said to be connected to each other like the front and back sides of a coin. The philosophy of human resources was presented in five dimensions: human, historical, social, economic, and management. The human resource model from eight factors: mastery, rationality, wisdom, customer orientation, innovation, flexibility, autonomy, collaboration. This study suggested that general talent model may vary depending on the company's type, empirical follow-up studies are needed the talents in each company in the future.

The major purposes of the research are to see the underlying disciplines of technology innovation management which contribute to Korean research. To do that, we employed author cocitation analysis which has been proved to be robust. We compiled all the citations of two major Korean journals between 1993 and 2006. We also included up to 3rd author, which makes a cocitation analysis more comprehensive, compared with the previous analysis for the first author only. We identified 239 authors who have more than 10 citations. From the cocitation combinations based on the 239 authors, we selected and analyzed 100 most cocited authors. Out of 100 authors a group of 23 authors who command both higher citations and cocitations were chosen for detailed analysis. The results show that the average number of publications is 22.2, the average number of citations to them is 58.5, and the average number of citations to a publication is 2.6. Also, the average number of cocitations is around 10 times that of citations. The results indicate that there are six major disciplines: Technology/Innovation, Management of Technology, Economics of Technology, Development, Valuation of Technology, and Growth. Noteworthy points are the following. 1) Most of the members of the technology management group are management scholars, and the groups of economics of technology and growth are economists, while the groups of technology innovation and development group are not represented by specific disciplines. 2) Considering the groups overall from the traditional academic disciplines, the main branches are management and economics. 3) The valuation of technology group consists mostly of Korean researchers.

지속가능발전은 인류가 추구해야할 공통의 목적이며 가치로서 사회적 지속가능성, 경제적 지속 가능성, 환경적 지속가능성의 개념이 내포되어 있다. 본 연구에서는 우리나라의 전력공급 부문에서 특히 사회적 지속가능성의 가치를 구현하기 위해서는 에너지 사용에 대한 형평성과 에너지를 생산하는 발전기술에 대한 사회적 수용성, 그리고 지속적으로 고용을 창출할 수 있는 발전기술들로 발전원을 구성되는 것이 필요하다고 보았다. 이를 위해 본 연구는 사회적 지속가능성을 '에너지복지', '기술의 수용성', '고용 창출'등 3가지 핵심 속성으로 나누고 속성 당 2개의 세부 속성 지표를 구성하여 총 6개의 속성지표 측면에서 발전기술별로 비교 분석하였다. 분석 결과, 사회적 지속가능성 종합점수는 원자력 > 풍력 > LNG > 석탄 > 태양광 순으로 나타나 원자력이 사회지속성 측면에서 가장 우수한 발전기술인 반면에 태양광은 가장 열위에 있는 것으로 평가되었다. 또한 속성별로 살펴보면, '에너지사용의 복지성'은 원자력과 석탄화력이, '에너지사용의 접근성'은 LNG와 석탄이, '기술의 안전성'은 원자력과 풍력이, '기술의 신뢰성'은 발전기술간 큰 차이가 없으며, '고용 규모'는 태양광과 원자력이, '고용의 질'은 풍력과 원자력이 우수한 것으로 나타나 원자력이 대부분의 속성에서 우위에 있거나 경쟁력이 있는 것으로 나타났다.

What has been the contribution of industrial innovation to economic growth? Typically, the issue has been approached with growth-accounting methods augmented to include a "stock of knowledge". An independent estimate of the rate of return to R&D is found in order to impute patents granted to the accumulation of knowledge. Griliches(1973) then uses a regression approach to assess the effect of an R&D variable on the computed TFP growth rate. The regression coefficient on the R&D variable would provide an estimate of the social rate of return to R&D. The related studies tend to show high social rates of return to R&D, typically in a range of 20 to 40 % per year. We need to provide multiple equation dynamic system for productivity and innovation in Korean economy in state space form. A wide range of time series models, including the classical linear regression model, can be written and estimated as special cases of a state space specification. State space models have been applied in the econometrics literature to model unobserved variables like productivity. Estimation produces the following results. Considering the goodness of fit, we can see that the evidence is strongly in favor of the range $0.120{\sim}0.135$ for the elasticity of TFP to R&D stock in the period between 1970's and the early 2000's.

A recently developed tunnel section enlargement method can maintain traffic flow during construction by using a protector. By keeping traffic flowing, it can minimize the lost time and costs associated with diversions and also the accompanying environmental pollution. On the other hand, installing the protector can lengthen the construction period and increase the direct cost. This paper presents a method for analyzing the economic feasibility of tunnel section enlargement methods considering the direct construction cost and the indirect social cost. The indirect costs are divided into categories of: vehicle driving cost, travel time delay cost, and environmental pollution cost. The economic efficiency of existing technology is compared with the new method in an case study of Namsan Tunnel 3.
