  • This study's purpose is to promote the development of CT industry by analizing the causal relationship between technology factor and commercialization of Tech. in CT SMEs and Ventures. The result is that Only technology experience accumulation among technical factors(technology develpoment cost, technology experience accumulation, technology concentration, technical expertise) has a significant effect on commercialization success or failure and non-technical factors have not a significant effect on.

  • Technology transferors and technology transferees decide to transfer technology with various motivations as they share benefits and risks. On top of economic benefit factors and risk factors provided by technology transferees, technology transferors also make technology transfer decisions by taking into account various factors such as government policies and systems, as well as their management strategies. In this study, the factors influencing the technology transfer in the chemical industry and the influence on the technology transfer intention are analysed. As a result of this study, factors influencing technology transfer are economic benefit factor, technological factor, risk factor, and socio-cultural factor. A significant differences in the influencing factors between the technology transferors and the technology transferees are that the economic benefit factors are more considered by the technology transferees and the technological factors are more considered by technology transferors in technology transfer. Technology transferees shows the stronger intention to enter technology transfer than the technology transferors.

  • The future will see all industries become technology-driven in the competitive global marketplace. Venture firms with deep technological roots and innovation strategies have some advantages. In this situation, existing methods for technology assessment are not enough to evaluate their relative technology competitiveness. Therefore, a more useful and comprehensive approach is needed to obtain the desired outcomes for measuring the relative competitiveness of technology effectively. In this research, I applied factor analysis, which is methodology to be capable of determining the common factors and associated weights reasonably, to the development of the technology competitiveness indexes.

  • The construction of roads, tunnels, and bridges results in changes to the local terrain that may influence the ground safety factor, which represents the stability of geotechnical structures. In this study, we assessed construction sites that had collapsed as a result of terrain change, and then simulated variation in the ground safety factor with respect to terrain change caused by road construction. We assumed steep slopes to simulate changes in terrain in a mountainous area and assumed that earthworks took place for road construction by cutting a platform into the slope and altering the slope angle of the terrain both above and below the road. We calculated values of the ground safety factor through a stability analysis of the slope both above and below the road, and examined the variation in the safety factor of the above- and below-road slopes with respect to changes in road width. We found that if the slope angle was the same above and below the road, then the change in the ground safety factor during/after road construction occurred in the slope below the road, and if the slope angle above the road differed from that below, then the change occurred in both the above- and below-road slopes. Furthermore, the ground safety factor was essentially constant for road widths exceeding 2-6 m, depending on both above- and below-road slope angle. The findings of this study can be used to guide the management of construction sites and to assess changes in ground stability during road construction work, particularly in the early stages of earthworks, when the road width is narrow.

  • The volatile components in Gamdongchotmoo kimchi, unfermented and fermented for 3 or 25 days, were extracted via solvent-assisted flavor evaporation (SAFE), and then analyzed via gas chromatography/mass spectrometry (GCMS). A total of 57 components, including 14 S-containing compounds, 22 terpene hydrocarbons, 13 aliphatic hydrocarbons, 4 alcohols, and 4 miscellaneous components, were detected in Gamdongchotmoo kimchi. Among them, the S-compounds were quantitatively dominant. The aroma-active compounds were also determined via gas chromatography-olfactometry (GC-O), using aroma extract dilution analysis (AEDA). A total of 16 aroma-active compounds were detected via GC-O. The most intense aroma-active compounds in Gamdongchotmoo kimchi included 4-isothiocyanato-1-butene ($Log_3$ FD factor 7, rancid), an unknown($Log_3$ FD factor 7, spicy) and another unknown ($Log_3$ FD factor 7, seasoning-like). In addition, other aroma-active compounds, including dimethyldisulfide ($Log_3$ FD factor 6, rotten onion-like/sulfury), 2-vinyl-[4H]-1,3-dithiin ($Log_3$ FD factor 5, spicy/garlic-like), and an unknown ($Log_3$ FD factor 5, rancid/cheese-like) might be crucial to the flavor characteristics of Gamdongchotmoo kimchi.

  • In this paper Statistical Energy Analysis has been considered to predict high frequency air borne interior noise. Dash panel Insulation is major part to reduce engine excitation noise. Transmission loss and absorption coefficient are considered to predict dash insulation performance. Transmission lose is derived from coupling loss factor and absorption coefficient is derived from internal damping loss factor. Material Biot properties were used to calculate each loss factors. Insulation geometry thickness distribution was hard to measure, so FeGate software was used to calculate thickness map from CAD drawing. Each predicted transmission losses between conventional insulation and light weight insulation were compared with SEA. Transmission loss measurement was performed to validate each prediction result, and it showed good correlation between prediction and measurement. Finally interior noise prediction was performed and result showed light weight insulation system can reduce 40% weight to keep similar performance with conventional insulation system, even though light weigh insulation system has lower sound transmission loss and higher absorption coefficient than conventional system.

  • The effective buckling length factor is an important parameter in the elastic buckling analysis of steel structures. The present article aims at developing a new method that allows the determination of the buckling factor values for frames. The novelty of the method is that it considers the interaction between the bracing and the elastic supports for asymmetrical frames in particular. The approach consists in isolating a critical column within the frame and evaluating the rotational and translational stiffness of its restraints to obtain the critical buckling load. This can be achieved by introducing, through a dimensionless parameter 𝜙i, the effects of coupling between the axial loading and bending stiffness of the columns, on the classical stability functions. Subsequently, comparative, and parametric studies conducted on several frames are presented for assessing the influence of geometry, loading, bracing, and support conditions of the frame columns on the value of the effective buckling length factor K. The results show that the formulas recommended by different approaches can give rather inaccurate values of K, especially in the case of asymmetric frames. The expressions used refer solely to local stiffness distributions, and not to the overall behavior of the structure.
