This study examines the approach of socio-technical systems and strategic niche management. It reviews the characteristics of that approach such as multi-level perspectives, the views on technology, and policy orientation. It applies the approach to the long-term vision making in science and technological innovation, socio-technical planning, participatory R&D, and science communication in Innovation policy areas and suggests some policy implications.

It is widely known that KMS (Knowledge Management System) plays a role of facilitator that contributes to upgrading the organizational performance. Despite this widespread belief, actual operation of KMS has been stalled at the level of being used only for the plain knowledge administration, not reaching the level of utilizing KMS strategically. In this sense, this case study suggests three successful KMS operation strategies-personalization strategy, socialization strategy, and technological strategy. Cases adopted in this study include HIRA(Health Insurance Review & Assessment Service) and KORAIL (Korea Railroad) where KMS has been successfully utilized to improve their organizational innovation and performance as well. Through scrutinizing the two cases, it was concluded that the proposed three KMS operation strategies have potentials of being generally applied to other KMS operation cases.

Recent technological advance have greatly expanded the application of invisible orthodontic treatment using clear thermoplastic materials. However, the final outcomes using clear aligner system do not achieve the level of final goal frequently, which results in case refinement, midcourse correction, or fixed orthodontic treatment. Therefore, mechanical properties of thermoplastic materials should be considered to improve the quality of outcomes. The purposes of this special article were to evaluate the force and stress depending on the materials, deflection and thickness of thermoplastic materials and to evaluate the mechanical properties of thermoplastic materials after repeated loading. Thickness and amount of deflection rather than products and materials showed the largest effect on force and stress. In all products, at least 159 gf of force was required for more than 1.0 mm deflection or when materials with 1.0 mm thickness were deflected. Orthodontic forces delivered by thermoplastic materials depend on the materials, thickness, amount of activation, and intra-oral condition. Proper thickness of thermoplastic materials and deflection level of tooth movement should be decided for the efficient and physiologic tooth movement.

This research proposes the use of a patent analysis methodology that can suggest promising technology in the ICT sector at the micro-level. This approach identifies core patents from the technology field, groups them as research frontiers (RFs), and develops a visualized network based on the citing relationships to monitor the relationship among RFs. In addition, it calculates a "promising index" based on the growth potential, impact, and marketability of patents to ultimately derive promising RFs. To illustrate the proposed approach, this research presents analysis results for a chosen area, which is the user interface and user experience (UI/UX) technology field. By proposing promising technological fields at the micro-level, the proposed methodology will serve as a useful decision-making support tool in selecting R&D projects, technology planning, and determining technology policy direction.

In this study, factors affecting the development of new products and research about the relevance of the factors based on the research model was configured. Existing research and technology commercialization process of discrimination that occur in the importance of risk management and open innovation company's competitive advantage in new product development and affect the reporter know what the effect is used as a control variable effects. Factor in the development of new products through research and innovation capacity and knowledge management activities, the introduction of open innovation and enterprise level ever due to the level of risk management controls and the need for effective research to study the model was proposed.

For ultra-pure water, the removal of various impirities is required, and the requirement level is rising year by year. To cope with this problem, various removing technologies and system technologies have been developed and the introduction of new materials for the piping, etc. to form the system have been positively made. For the element technologies to be used for ultra-pure water production, their range will be expanded from the technological and economic viewpoints. Therefore, it is absolutely necessary to develop trace analysis evaluation technologies for ultra-pure water. Especially to raise the analytical level of heavy metals and organic substances is important. It is also important to establish individual analysis methods of organic substances. It is expected that the analytical methods will be established and new treating methods will be put to practical use in the near future.

This paper investigates the structural responses of axially restrained steel beams under fire conditions by a nonlinear finite element method. The axial restraint is represented by a linear elastic spring. Different parameters which include beam slenderness ratio, external load level and axial restraint ratio are investigated. The process of forming a mid-span plastic hinge at the mid-span under a rising temperature is studied. In line with forming a fully plastic hinge at mid-span, the response of a restrained beam under rising temperature can be divided into three stages, viz. no plastic hinge, hinge forming and rotating, and catenary action stage. During catenary action stage, the axial restraint pulls the heated beam and prevents it from failing. This study introduces definitions of beam limiting temperature $T_{lim}$, catenary temperature $T_{ctn}$ and warning time $t_{wn}$. Influences of slenderness ratio, load level and axial restraint ratio on $T_{lim}$, $T_{ctn}$ and $t_{wn}$ are examined.

In order to facilitate the introduction of BIM technology in the construction project of fact, many countries such as Singapore and the United States, is developing a roadmap of BIM technology development. To develop this, recently, it must be analyzed in advance the state of BIM technology domestic projects. In this study, we define the elements of technology BIM, and analyzed the current situation. In addition, I was evaluated and priority importance to the elemental technology derived. As a result, elemental technology most was the level inferior to foreign countries, and the field of ordering standard planning and has been highly valued and priority of particular importance, but currently, the level of domestic, analysis and most delayed has been. These results are judged to be useful in the development of the roadmap and direction of technological development of BIM in the future.

In early 1956, MSG (monosodium glutamate) had been produced by hydrolysis of the vegetable proteins in Korea. In accordance with development of fermentation technology mainly led by the Japanese scientists, its major production method has been changed to microbial fermentation since 1962. Meanwhile, 5'-ribonucleotides which are nucleic acid-related condiments have been produced by the enzymic hydrolysis of yeast RNA and/or the direct fermentation by Miwon Co. and Cheil sugar Co., respectively since 1977. At the technological viewpoints, Korean fermentation level seems relatively highly-reputated over the world in terms of production yield and unit-consumption level. For further progress of technology, our emphasis on this research area should be laid on both improvement of bacterial strain by means of modern biotechnology and process development through the immobilization and/or computerized control technics, etc.
