The purpose of this paper is to suggest field-oriented policy of regional innovation support system. To accomplish this purpose, we examined the status quo of technical support ,performance satisfaction of consumers and practical issues. The key factors influencing core technical innovation of small and medium firms are development fund, R&D employees, experimental instrument, technical information, protection of intellectual property, subcontracting and so on. To make sure of practical effect, therefore, it would rather necessary to implement policy support linking government and supporting means on the ground of needs of small and medium firms than specific method such as funding.

The purpose of this study is to categorize group of firms by using characteristics of technical innovation in telecommunication industry and to identify relationships between types of technical innovation and such contingency factors of technical innovation. The major findings of this study are summarized as follows; First, Type 1 Group (Innovative Industry Leading Group) tends to use innovative and market differentiation strategy and has more innovative C.E.O's management style and innovative culture. Second, Type 2 Group (Dependent Group on Market Change) tends to use market differentiation or cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture. Third, Type 3 Group (Small Technology Intensive Group) tends to use focused innovative strategy and has a more innovative C.E.O's management style and innovative culture. Fourth, Type 4 Group (Non-Innovative Group) tends to use focused cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture.

Blasting is a technique for rock excavation: For instance, a rock cutting in a mountain side to prepare a base for a road. The blasting damage affect the rock slope stability. Therefore control blasting must be used. In this study, cutting cases of Sixty-nine rock blasts were investigated. Blasting damage patterns in rock slope and reinforcement methods are studied.

Falling rocks are classed by the collapse to wide meaning. it is a kinds of earth disaster that has happen every year. Falling rocks are defined as blocks which had fallen from the cliff. It is caused by the relaxation of discontinuous structures like as a joint, a foliation, a bedding, and so on. Usually, the Relaxation of blocks from the rock face is happened by various kinds factors that are acted as a complex. Sometimes, the tree can be a factor of the weakness or relaxation of rock blocks and a cause of the falling rock.

Although the national technical qualification scheme has a historical background for thirty-five years, it hasn't any study of an obvious cause analysis, effective counterplan and analysis relation to its historical changes. This paper analyses the internal and external factors of technical qualification policy of the Human resources development service of Korea using PEST and SWOT and surveys the influence on its environment and the variation cause of the ratio of successful applicants to the qualification scheme. This paper also suggests systematically the direction for development of the technical qualification scheme using FMEA. Thus, this study assists to construct rapidly a correspondence system to the environment change simultaneously to determine decision making to the marketing policy.

Recently, the long-term operation of a nuclear power plant beyond its licensed term has become a worldwide trend as long as the safety of the plant is maintained in the extended period. Kori Unit 1, the oldest PWR in Korea, is the foremost example of this type of long-term operation in Korea. Comprehensive technical evaluation of the long-term operation of this plant was completed to confirm the overall safety of the plant. The technical evaluation included a review of PSR results, an assessment on aging management programs and time limited aging analyses, and a statement of radiological impact on the environment. Based on all of the results of the technical evaluation activities, Kori Unit 1 was approved to operate for an additional 10 years beyond its original design life of 30 years.

The purpose of this paper was to measure technical efficiencies and scale efficiencies of Korean seed industry by DEA method, and to identify the factors affecting the efficiencies by Tobit regression model. Survey data of 50 seed companies nationwide were applied for the analysis. The average score of overall technical efficiency for the surveyed companies in 2012 was 0.44, which is decomposed into pure technical efficiency 0.68 and scale efficiency 0.63. A majority of the seed companies exhibited at least one form of inefficiency except a few companies in optimal scale. It was also shown the most companies were operating in the stage of increasing returns to scale, which implies Korean seed companies are mainly in smaller scale than optimal. Additional results suggest that the Center for Private Seed Companies, which will be established at Gimje in 2015, plays an important role to make domestic seed companies improve their scale efficiency as well as pure technical efficiency by way of enlarging their size and co-using the high technology in the Center.

The purpose of this paper is output oriented, in order to maximize the output level of sustainable development efficiency of foreign trade in western China with limited input. This paper adopts the relevant input-output indicators of sustainable foreign trade development of 11 provinces and cities in western China from 2016 to 2020, and uses DEA model to measure their technical efficiency, pure technical efficiency and scale efficiency. Malmquist index was used to calculate the total factor productivity change index of each province in western China from 2016 to 2020. We found that, on the whole, the average values of technical efficiency, pure technical efficiency and scale efficiency of provinces and cities in western China from 2016 to 2020 are greater than 0.8, indicating that the western region has high technical efficiency, relatively high management and institutional level and high existing scale level. Scale efficiency is lower than pure technical efficiency on the whole, indicating that the current sustainable development efficiency of foreign trade in western China is mainly limited by its scale level. The technological progress index is higher than the technological efficiency change index, indicating that the total factor productivity of the sustainable development of foreign trade in western China is mainly driven by technological progress and more influenced by external factors. We think the conclusion of this study can provide important reference information for the sustainable development of foreign trade of provinces and cities in western China.

A big success of the 3D film 'Avatar' in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..
