A stock valuation on the tax law is based on the valuation by market price. But, unlike the listed stocks, the unlisted stocks mostly have the unclear market price. Accordingly, it is necessary to calculate the fair value which corresponds to the market price. The purpose of this paper is to examine the appropriateness of the complementary valuation method in the Inheritance Tax and Gift Tax Act and to provide suggestions for improvement. This study is intended to provide the problems and solutions relating to the valuation of unlisted stocks through analysis of foreign legal systems and actual disputes. When the actual profit/loss data are used to calculate the net profit/loss value on the present regulations, it has the different weight on the latest 3 years' net profits and losses uniformly. Therefore, to extend the range of unlisted stocks valuation and to show the independent and high professionalism of appraisal council not the subsidy appraisal agency of the National Tax Service, it is necessary to change the current rule that the commissioner of the National Tax Service unilaterally appoints the private members into the method of public offering.

The objective of this research was to estimate residents' willingness-to-pay using contingent valuation method and to investigate their environmental sensibilities prior to conduct the costbenefit analysis on the watershed management program of integrated sewerage construction and operation in the catchment of Dam Chung-Ju. A set of questionnaire was prepared and asked to 1,200 residents at downstream area as well as upstream area of Dam Chung-Ju. As a result, environmental sensibility of the residents living in the catchment of upstream of Lake Chung-Ju seemed very high. However, the substantial practice in their own life for conserving their environment was inactive, although residents' efforts trying to collect and dispose garbages in separate containers and to minimize the waste discharge load were actually made. The willingness-to-pay on each month for 20 years was estimated as 4,841 wons for the openended question and 3,411 wons for the close-ended question. Factorial analysis was also performed to obtain correlation among the questions asked. Seven groups of the correlated questions were identified and their contribution to the estimated willingness-to-pay was analyzed.

The mobile commerce (m-commerce) has very high market value unlike other technology innovation areas in IT industries and also changing rapidly. Therefore, it is fact that the development of the effective business strategy is challenging in a digital convergence era of m-commerce context. In most of the researches, m-commerce has dealt with conceptual study such as establishment of definition. There are not many studies of influence of information valuation evaluation on users' satisfaction have done so far. In this paper, we have reported a theoretical study as well as empirical analysis and examined an influence of information valuation evaluation have on users' satisfaction. A questionnaire was constructed and data were collected from 192 users of m-commerce system. The results indicated that users' satisfaction was affected by information valuation evaluation and difference between cost satisfaction and service quality satisfaction according to users' specialty.

Since technological innovation is such an important factor that it can determine a company's economic growth and competitive enhancement, all the companies make lots of investments and efforts for technological innovation. As outcomes of technological innovation, there are patents, trademark and copyrights, etc. and they are mostly approved as a legal right called 'Intellectual Property Right'. To activate such an intellectual property right, financing techniques are needed for enterprises to raise funds through collaterals, such as technological and intellectual patents. In reality, however, any IP-related financial system is not really activated due to the lack of surety-related regulations in Korea. Thus, on the premise that it is important to carry out an objective and reliable valuation on IP as a collateral for the activation of IP finance, this study intends to investigate various different methods of patent valuation needed for IP finance.

In this paper, we discuss patent pool and a patent valuation scheme for fair royalty distribution among the patents in a pool. In the knowledge-based economy, intellectual capital-the accumulation of technology and know-how-is recognized as the most important source of company's competitive advantage and economic growth. By providing exclusive rights to patent holders, the patent system aims to encourage innovation-invention & commercialization of new technologies-in order to raise the standard of living. However, drawbacks of patent system, which occur as the number of patents issued increases rapidly and patent ownership is fragmented, may slow down the innovation efforts seriously. A promising solution is the patent pool approach, which was for instance employed by the U.S. congress during World War I to free the airplane manufacturers from the patent tangle by letting them license all the patents for a fee. It is necessary to figure out relative technological contribution of patent for fair distribution of royalty revenues among patent holders. The Rating/Ranking Method seems to fit to that valuation purpose. We examined technology valuation models from various organizations and selected a set of more influential valuation factors which can be incorporated as scoring criteria in the Rating/Ranking Method.

For securing technology and business competences of companies that is the engine of domestic industrial growth, government-supported policy programs for the creation of commercialization results in various forms such as 『Technology Transaction Market Vitalization』 and 『Technology Finance-based R&D Commercialization Support』 have been carried out since 2014. So far, various studies on technology valuation theories and evaluation variables have been formalized by experts from various fields, and have been utilized in the field of technology commercialization. However, Their practicality has been questioned due to the existing constraint that valuation results are assessed lower than the expectation in the evaluation sector. Even considering that the evaluation results may differ depending on factors such as the corporate situation and investment environment, it is necessary to establish a reference infrastructure to secure the objectivity and reliability of the technology valuation results. In this study, we investigate the evaluation infrastructure built by each institution and examine whether the latest artificial neural networks and deep learning technologies are applicable for performing predictive simulation of technology values based on principal variables, and predicting sales estimates and qualitative evaluation scores in order to embed onto the technology valuation system.
