The future will see all industries become technology-driven in the competitive global market place. Firms with deep technological roots and innovation strategies have some advantages. Business valuation of technology is critical to the future of firm's business. In this situation widely used scoring valuation is not enough to evaluate relative business competitiveness associated with technology and to assign its relative ranking category. Therefore, a more useful and comprehensive new valuation approach, which is called business composite index, is needed to complement and to enhance the existing scoring valuation approach. In this research, statistical factor analysis is applied to determine the common factors and to estimate associated weights. And business composite index, which is a kind of weighted scoring method, is derived based on the results of factor analysis. This research shows that business composite index is considered very useful to measure the business relative strength of individual technology and also to assign its relative ranking category instead of absolute ranking based on scoring valuation approach.

The government introduced a mandatory installation system of new & renewable energy for public building to meet the target of greenhouse gas reduction and also suggest a correction factor for new renewable energy to expand the installation of various new & renewable energy systems. The introduction of correction factors, however, was followed by the reduction of installation size of new & renewable energy sources. Assuming that it was caused by a correction factor for each new renewable energy source calculated by the initial costs, this study proposed a new correction factor approach based on payback periods to reflect the technology element in the calculation process of correction factors additionally. The application results of new correction factors show that it was possible to do complex calculations including the economic and technological aspects to select a new & renewable energy system and that the installation size was also enlarged.

The purpose of this study is to examine the effects of the factors that hinder innovation of SMEs on innovation activities of Korean firms. Many existing literature studies remain focused on factors that promote innovation activities. However, in order for companies to promote innovation, it is important to analyze the factors that hinder innovation as well as those that promote innovation. In this study, we analyzed the relationship between technological innovation inhibition factors and technological innovation performance of 4,075 SMEs in Korea using the Korea Institute of Science and Technology Policy statistical data. The research model and hypothesis test of this study consist of three stages. First, the reliability of the variables used was verified using exploratory factor analysis. Second, the proposed hypothesis was modeled using structural equation modeling. Finally, validity of the structural equation was verified using confirmatory factor analysis. As a result, the lack of need for innovation influenced innovation performance and the government support system mediated them. SMEs should establish technological innovation strategies to maximize the effect of technological innovation with limited resources, and government should make polices to promote innovation of SMEs. It's expected to be used in the case of establishing a support policy.

Based on Income-approach, this study develops the evaluation model which reflects construction industry's traits. Using Income approach, we derive future income's present value and evaluates the technological value by contribution to future income. As there exist more random variables in construction technology than in standardized manufactured products, we cannot help relying on not only quantitative estimation method but also qualitative evaluation by technology and market experts when we estimates construction technology value. Also, conservative estimation is needed for discount rate and cash-flow estimation, because of high uncertainty in sales and profits in construction industry. In empirical analysis, we applied economic periods of duration and cash-flow based on the standard guideline, and analyzed discount rate and technology factor based on characteristics of construction industry. The discount rate is estimated to 15% because of risk-premium increase by conservative evaluation. Technology factor is estimated to 46.7%, because technological intensity is estimated to 72% by technological superiority. Such implications can be inferred. Firstly, we need to build a database to diversify categories for division of sectors by activity or industrial classification which is now categorized only by two sectors in standard guideline. Secondly, the roles of experts who participate in technology evaluation are important because of volatility of construction technology.

The construction of a new cavern modifies the state of stresses and displacements in a zone around the existing cavern. For multiple caverns, the size of this influence zone depends on the ground type, the in situ stress, the cavern span and shape, the width of the pillar separating the caverns, and the excavation sequence. Performances of underground twin caverns can be unsatisfactory as a result of either instability (collapse) or excessive displacements. These two distinct failures should be prevented in design. This study simulated the ultimate and serviceability performances of underground twin rock caverns of various sizes and shapes. The global factor of safety is used as the criterion for determining the ultimate limit state and the calculated maximum displacement around the cavern opening is adopted as the serviceability limit state criterion. Based on the results of a series of numerical simulations, simple regression models were developed for estimating the global factor of safety and the maximum displacement, respectively. It was proposed that a proper pillar width can be determined based on the threshold influence factor value. In addition, design charts with regard to the selection of the pillar width for underground twin rock caverns under similar ground conditions were also developed.

Technological advance in information technology has sparked the necessity of small form factor (SFF) optical disk for mobile devices. Small form factor optical disk is highly anticipated to be a next generation storage device because it can be used for a cost-effective way compared with solid state memory. For the application to the 5 mm height small-form-factor optical disk drive, we have presented an optical flying head and swing arm actuator. In this study, we propose a small 1-axis actuator for compensating ficus error and SA due to the variation of cover-layer thickness in the cover-layered small optical disk. The main design issues of the 1-axis actuator are the realization of compact structure and the new support structure of the actuator: Finally, the compensating principle and performance of the 1-axis actuator will be explained.

This study investigates the effect of entrepreneurship on corporate performance highlighting the mediating role of technological innovation and the moderating role of marketing competence. By identifying the role of technological innovation and marketing competence within the relationship between the entrepreneurship and corporate's business performance, this study aims to improve SMBs' competence. Special attention was given to the fact that while there are some technology-based SMBs which have achieved positive outcomes through innovation, there are some other firms which have not been able to deliver expected outcomes despite of their technological competence. The data used in this study came from CEO or chief research executives of SMBs. Results of the data analysis show that the innovative sprit which is an important factor of entrepreneurship has an positive effect on technological performance, financial performance and non-financial performance. However, risk- taking tendency has an positive effect on technological performance but negative effects on financial and non- financial performance of the firms. This study also has examined the mediating effect of technological innovation on the relationship between entrepreneurship and corporate's performance and the result reveals that technological innovation plays a mediating role within the relationship. Specially, innovative spirit plays a full mediating role within the relationship between technological commercialization capacity and financial and non-financial performances of SMEs'. Also, risk taking tendency has a full mediating effect on the positive relationship between strategic planning capability and both financial and non-financial performance. Regarding the moderating role of marketing capability within the relationship between the entrepreneurship and the performance of the firms, results of data analysis shows as follows. Marketing professional capability plays a moderating role between risk taking tendency and performance of the firm and marketing structural capability plays a moderating role between innovative spirit and the performance of the firms. Based on these results, this study confirms that SMEs' business performance is effected by entrepreneurship. Innovative spirit plays a mediating role within the relationship entrepreneurship and business performance. However, Marketing capability has a partial moderating effect on the relationship between the entrepreneurship and the business performance.
