This study aim to analyze the factors affecting technical support input and performance of companies benefiting from ICT SME technology support operated by ETRI. In order to analyze the data, we surveyed 181 companies who received technical support between 2015 and 2017, and analyzed the relationship between input factors and performance factors through path analysis. As a result of the study, it was found that the service quality was directly influenced on the improvement of technology level, and the cost reduction effect was influenced by the amount of support, the year of support, and the service quality. Also, input factors affecting contribution sales are the amount of support, and the support year and quality of support services are not effective. Finally, as a result of examining the effect of technological and economic performance on job creation, it is found that the effect of job creation increases as the contribution sales increase.

It has been 3 years since the TV broadcasting industry migrated to the UHDTV broadcasting service. Theoretically UHDTV picture quality is four times better than HDTV. UHDTV broadcast has been put to practical use by domestic broadcasters, excluding public broadcasters. The resolution of UHDTV does not correspond to the standard UHDTV values, the viewer have no choice but to watch existing contents on UHDTV. Therefore this paper analyses the current broadcast technology level for the image quality improvement, and to investigate the bandwidth of UHD broadcasts. In this paper we have studied current condition of HDMI interface technology and suggesting Super MHL interface technology capable of performing a successful establishment of the new broadcasting platform in future 8K UHD broadcasts alternatively. In order to improve the UHD broadcasting, we are expecting the development change of UHD broadcasting service user experience.

This study purports to investigate the difference between upward and downward feedback and to find out the strategy to enhance the validity and reliability of the multi-source feedback system. Data were collected from 88 middle-level managers working at divisions of nursing, administration, and clinical technology at a university hospital located in north-eastern part of South Korea. Data about multi-source feedback of the year 2008 and 2009 were obtained from the department of personnel management under the permission of hospital top management. The collected data were analyzed using t-test, and correlation analysis. The major findings of the study were as follows: First, the scores of downward feedback were always higher than those of the upward feedback. Second, the scores of downward feedback were always higher than those of the upward feedback in both nursing and administrative staff, while no significant difference was found in technological staff. Third, the upward and downward feedback scores were significantly different in terms of the evaluation factors. Fourth, there were significant correlations between total scores of downward and upward feedback, and evaluation factor scores. In conclusion, the composition and weight of measurement items of multi-source feedback needs to be designed differently in terms of each job characteristics.

This study aims at understanding the characteristics of global economic models, which are widely used for climate change policy analysis. A literature review study was conducted in order to derive general features of top-down models such as CGE and bottom-up/hybrid models such as GTEM. Furthermore, a structural analysis was carried out by applying parameter and structural components from other models to a particular model to observe the potential differences in outcomes. Literature review shows that bottom-up or hybrid models generally have higher level of reduction potentials than top-down models in the long run. This contradicts the conclusion presented by IPCC, and raises the need for more rigorous investigation through structural analysis. Structural analysis of EPPA model indicates that the structural component of the energy sector in a particular model is the most influential factor in predicting baseline emissions and reduction potentials. This includes the structure among energy, capital, and labor inputs, and the substitution elasticities within the energy bundle. Technology bundle can establish the conclusions from literature review, and change in Armington elasticities do not significantly affect the outcome in aggregate.

During the recent decades in democratic and industrialized countries, government policies for governing technological innovation and risks to environment and human health have undergone significant changes. The shift from a top-down legislative approach to a more inclusive and deliberative atmosphere is, putatively the most prominent change. Such a move is often described as a move from government to governance. In the governance of technology and risk, public engagement has been a major strategy in technology decision-making process. This article aims to look into the changes in the procedural modes of technology decision-making process. It discusses the main viewpoints that have been placed on the basis of such a move. Also, it further relates the changes in local decision-making process to science and technology decision-making at global level. It argues that the democratic and reflexive trends in local science and technology decision-making will be the basis upon which to shape and respond to global governance system: while international decision-making process would require accountability in integrating different values and rationalities, such accountability may be sustained and reinforced depending on the robustness of the local decisions and social choices.

A technology transfer from public research centers or national universities to a company is an increasing phenomenon. The purpose of this study is thus to identify the major evaluation criteria of technology transfer from a company viewpoint and establish the importance weights of criteria through 2 level AHP analysis. First, 12 critical elements are extracted from previous studies and professional interview and these elements are tied into 4 factors; technological factor, organizational factor, environmental factor, and strategic factor. The results of AHP analysis show that strategic factor is more important and 'the growth of the technology' in the strategic factor is the most important element. This study will be used usefully when researchers in public research centers or national universities try to develop a technology considering a technology transfer to the other company.

This paper presents a knowledge-based view of platform-centered collaborations among multiple organizations. Studies of technological innovation and knowledge creation have broadened beyond their initial emphasis on internal development within an organization or simple exchange of ideas between two parties toward complex collaboration among many organizations at the level of platform-based knowledge ecosystems. Platforms serve as an interface between different groups of producers and consumers in a variety of multi-sided knowledge markets such as smartphone operating systems and video games industries. This study is an exploratory examination to offer theoretical understanding of how the organizational capabilities of platform leaders help expand a network of platform participants. The growth of platform participants is particularly important in the early stage of any platforms as the concept of network effects suggests that the platform with the largest number of participants will capture entire markets. Building upon organization studies and network economics theory on multisided markets, this paper focuses on the role of platform leaders in expanding platform-based collaboration. In our view, platform leaders develop varying levels of three organizational capabilities to discern quality of potential participants, to attract them to actually participate in collaboration, and to maintain long-term exchange relations in the ecosystem. We suggest that the capabilities of platform leaders will have a positive effect on the expansion of platform participants to secure network effects, and also examine several contextual factors that moderate the relationship between a platform leader's capacity and platform expansion.

In this rapidly changing information society, the needs for professional technicians in IT-related industrial fields are increasing, but the supplies of such men are not enough. A well-designed educational program is required in order to produce outstanding technicians in this up-to-date information-centered industrial environment. It is widely recognized that the educational program of two-year level college today should be improved because it has been mainly oriented to train or exercise short-term skills with a few basic theory. With this educational program, it is not easy to achieve the original educational goal to cultivate and to produce the specialists to be equipped with both technological and intellectual skills. Therefore, new three-year academic educational program is expected to accomplish that goal. This paper is aimed to offer a model of a new educational program on three-year academic system, which would help to meet IT industry's requirements.

Tunnel sections on the expressway are different from rest of sections on the expressway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Thus, this study tried to find out qualitative factors affecting speed reduction in tunnel sections based on questionnaire surveys and its analysis in tunnel sections selected by taking consideration of diverse conditions. Analysis showed that factors concerning tunnel configuration (lane width, shoulder width, and tunnel length) related to very long tunnels increasingly popular recently had some effects on reduced speed inside of tunnels. It appeared that visual environment such as visibility of tunnel entrance had an impact in speed reduction and vehicle speed tended to change according to lighting illumination level inside of tunnels. It is expected that continual investment would be made in technological development related to expressway tunnel design and service improvement based on this study.

Diverse benefits such as reduction of fresh water consumption and effluent discharge, efficient use of raw materials and energy savings can be obtained by papermaking system closure. Closure of papermaking processes, however, causes many problems including reduction of the efficiency of additives, decrease of retention and dewatering, felt plugging, poor Paper quality, generation of slime and odor, poor vacuum efficiency, etc, and it has been recognized that accumulation of Inorganic and organic substances in the process white water is the prime cause of these problems. Therefore, technological developments for preventing accumulation of these detrimental substances are urgently required for Implementing papermaking system closure. Understanding of the accumulation phenomena of the inorganic and organic substances in the papermaking process white water is prerequisite for papermaking system closure. In this study a process simulation method was used to analyze the accumulation phenomena of anionic starch In the process white water as the closure level of a fine paper making process is increased. A pilot paper machine was used as a model process. Starch adsorption and desorption models were developed based on the concept of starch adsorption ratio, which was not considered in previous studies. Steady state simulation studies were carried out based on this model using a commercial simulator. In steady state simulation, the variation of dissolved starch concentration in each process unit was monitored as a function of white water usage for wire shower. The result of the steady state simulation showed that dissolved starch concentration and its increase ratio in Process units increased as white water usage ratio for wire shower increased.
