본 논문에서는 기존의 기술가치평가모형들을 검토하여 문제점과 한계를 찾아내고, 이를 극복할 뿐만 아니라, 기술의 실제가치에 접근하고자 새로운 시도를 하였다. 먼저 1단계에서는 DCF 모형을 이용하여 사업가치를 계산하고, 2단계에서는 사업가치에서 무형자산이 차지하는 비율이 산업별로 서로 다를 것이라는 가정아래 사업가치 창출에 대한 무형자산의 기여도를 구했다. 그리고 3단계에서는 전체 사업가치 창출에서 기술의 기여가 차지하는 비중을 측정하는 기술의 기여도를 구했다. 이렇게 3단계에 걸쳐 얻은 결과를 동시에 고려하여 기술가치를 산출하였다. 그리고 마지막 4단계에서는 전 단계에서 고려되지 못했던 미래수익 창출의 불확실성을 반영하기 위해 실물옵션모형을 적용하였다. 이와 같이 평가과정을 4단계로 구분하고, 각 단계별로 평가의 특성에 맞는 방법을 채택함으로써, 기존의 평가모형이 가지고 있었던 문제점과 한계를 극복하고, 불확실성이 높은 기술자산의 실제가치에 보다 근접할 수 있었다.

The purpose of this paper is to investigate the value chain efficiency of Korean port investment by using the newly developed multi-year and multi-stage value chain efficiency model of DEA(Data Envelopment Analysis). Inputs[port investment amount, cargo handling capacity, and berthing capacity], and outputs[cargo handling amount, number of ship calls, revenue, and score of customer service satisfaction] are used during 14 years(1994-2007) for 20 Korean seaports by using two kinds of DEA models. Empirical main results are as follows: First, Model 1 shows that the ranking order of multi-stage value chain efficiency is Stage 2, Stage 3-1, Stage 1, and Stage 3-2. And according to the value chain average efficiency scores, ranking order is stages 2, 1, 3-1, and 3-2. In Model 2, 3(Incheon, Mogpo, and Jeju) out of 9 ports show the ranking order of Stages 2, 3-2, 3-1, and 1. And value chain average efficiency scores rank in order of Stages 2, 3-2, 3-1, and 1. Second, the difference among the value chain efficiency scores of each stage comes from the efficiency deterioration of all ports except Stages 2 and 1 in Model 1. In Model 2, value chain efficiency scores among the Stages 3-1, 3-2 compared to Stage 1 were deteriorated. The main policy implication based on the findings of this study is that the manager of port investment and management of Ministry of Land, Transport and Maritime Affairs in Korea should introduce the multi-year, multi-stage value chain efficiency method for deciding the port investment amount and evaluating the effect of port investment after considering the empirical results of this paper carefully.

This research explores a value chain structure of VR-AR media including user's perception, uses, and evaluation. The purpose of this research focused on factor analysis and the relationship among user's VR-AR adoption motivations and utilities. This research explores correlation between personal value and using motivation. This study was to identify the value structure of respondent on VR-AR usages based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. This study is based on the analysis of the value chain structure factors that affect VR and AR use behavior (attributes, functional benefits, psychological benefits, use value), 'Hierarchical Value Map' between users' The purpose of the model is to construct a model. For this, 'means-end chain theory' was applied to measure the causal relationship between personal value and VR related use behavior. In order to solve this research problem, 135 people were analyzed through the structured questionnaire using the AR and VR content fitness measure and the second APT laddering, and the use of VR-AR : 1) Functional benefits; 2) Psychological benefits; 3) Means to reach value, 4) Objective value chain structure was identified. The results show that VR users tried to smooth the social life through the new virtual reality audiovisual element, the newness of experience, fun, and pleasure through the departure of reality, vividness of experience, and leading fashion. The AR fitness was a game and a new program, and the value of interacting with other people and the value of 'periwinkle' played an important role through the vividness and peripheral interaction of AR, It was an important choice. The important basic values of users' VR and AR selection were correlated with psychological attributes of interaction with others, achievement, happiness and favorable values.

Early stages of technology valuation have been often overlooked or under-represented. The early stage technologies are even riskier due to their inadequacy of commercial development and market applicability. More than 95% of patents fail to earn any revenues so that the majority of patents were valueless. Technology transfers from laboratories at universities and research institutes to industrial firms have increased to acquire value from invented technologies. Technology transfer, a process of transferring discoveries and innovations resulted from research to commercial sectors, typically comprises several steps: disclosing the discoveries and innovations, i.e., intellectual property (IP), evaluating the IP's economic prospects, securing a patent, copyright or trademark for the IP, commercializing the technology through licensing, forming a joint venture, or selling. At each of those stages in the research and development of technology, the value of technology would play a very important role of making decision on the movement toward the next step, however, the financial value of technology is not easy to determine due to a great amount of uncertainty in the course of research and development, and commercialization. This paper refers to technology embodied as devices, equipment, software or processes primarily developed at public research institutions such as universities. Sometimes it is also as the result of externally financed projects contracted with industry. Nearly always technology developed at public research entities results in laboratory prototypes. When it is required to define the technology transfer contract terms for the license of the university patrimonial rights to external funding companies or other interested parties, a question arises: what is the monetary value? In this paper, we present a method for technology valuation based on the identification of specific value points related to its development. The final technology value must be within previously defined value limits. This paper consists of the review of issues related to technology transfer and commercialization, the identification of characteristics of technologies in the early stage of technology development, the formulation of framework of methods to value the early stage technologies, and the conclusion and implication of the previous review.

Under the stiff competition in the health care industry, the long run survival of medical institution depends on building up customer loyalty. The purpose of this study is to figure out the influencing factors on customer loyalty. This new model is based on Bettman(1979)'s customer purchasing decision making process(awareness-interest-final decision). The key characteristics of this model reflects the psychological change of customer purchasing decision The influencing factor at each purchasing stage must need to be identified because the inner decision making process is generally carried out by multistage. In this respect, this study shows the brand awareness of hospital plays an important role at the first stage. In a second stage, the servciescape and service quality of hospital must be considered. Finally, customer's perceived value is adopted. By using a sample of 116 Chinese tourists, this study empirically examines the influencing factors of customer loyalty. The results that the brand awareness and perceived value have a positive effect on customer loyalty.
