FinTech is a technology-led financial transaction innovation that is a fusion of finance and technology. The main types of Fintech are remittance, payment, P2P, and financial data analysis. Duplex payments are spreading around the world. However, the P2P loan sector has not been well established due to the low social awareness in Korea despite the innovative change in Fintech. Therefore, in this study, we want to know that is the intention to use of P2P loan which can be considered innovative among FinTech types. Based on theory of reasoned action(TRA), FinTech is a convergence of IT technology, we have set up a research model by converging the “Technology readiness index(TRI)” theory of information technology. As a result of the analysis, it was confirmed that the ‘Subjective Norm’ and ‘Attitude Toward Behavior’ to the ‘Theory of Reasoned Action(TRA)’ had an influence on the intention of the act in the act of Fintech lending. However, in the Fintech loan, the ‘Technology readiness index(TRI) does not significantly affect the attitude. Among them, ’Optimistic’ and ‘discomfort’ were not affected. And the ‘Subjective norm’ is heavily influenced by the opinions of his important people. There was no ‘motivation to comply’ the opinion.

The activities regarding big data collection and analysis are expanding rapidly around the world. In particular, the growing use of wireless internet and smart phones enables to collect data about emotions. These days, people tend to express and communicate their feelings and opinions through a variety of social medias such as twitter, blog, Facebook and so on, and accordingly the vast amount of the relevant data have been accumulated both in the form of unstructured and structured data. These data have a potential to be a basis for valuable marketing tools, providing information about how people feel about products and services. Until now, great efforts have been made to extract significant knowledge from a large size of data but most of these efforts have focused on increasing the efficiency of data collection and processing. Few previous studies have addressed the issues regarding effective use of these data in practice. The value of data is determined by how well it is used. Therefore, this study aims to propose a methodology to derive a service model that can recommend cultural contents such as movies, musics, dramas in accordance with individual`` tastes and sensibilities using the data collected from the SNS(Socal Network Service). For this purpose, we firstly gathered two kinds of data - personal data on SNS and users’ evaluation on movies collected from communities. Then, keywords were extracted from the personal data to represent individual`` tastes or sensibilities. Thirdly, the sensibility keyword dictionary were developed to describe a variety of emotions in representative keywords. Fourth, using the dictionary, we analyzed the emotional condition of an individual from the keywords presented in their SNS. Finally, the emotional condition can be used as a tool for offering a personalized service, by recommending a movie most suitable for the condition.

Real Option을 활용한 R&D가치평가에 관한 연구:신약개발 R&D가치평가 사례를 중심으로
문성주,이철규,유왕진 한국경영공학회 2006 한국경영공학회지 Vol.11 No.2
Pharmaceutical and biotechnology companies must regularly introduce new products because of competition to current products and in order to capitalize on a new growth opportunity. Success of pharmaceutical companies is highly dependent on R&D. Most of companies perform some types of quantitative analysis such as NPV(net present value), IRR(internal rate of return) and payback in order to decide which of the alternative projects shoud be financed beforehand. Among these techniques NPV provides the best answer. But NPV approach may fail to evaluate R&D toward to the right way because it does not properly value management's ability to react proactively to the changes in future uncertainty. It means it does not consider the value of options to wait and revise the initial operation strategy.So, Traditional capital budgeting techniques such as Discounted Cash Flow (DCF) method assumes point estimates of future cash flows on predetermined of uncertainty over the course of the R&D, hence neglects managerial flexibility. To overcome the limitations of DCF method and to explicitly consider the value of flexibility, this study applied the real option approach to the new drug R&D valuation.

Increased usage of the computer mouse has been a essential factor affecting the musculoskeletal disorders(MSDs). The purpose of this study is to determine whether there are differences in wrist movement variations, forearm muscular loads, comfort and normal performance among a proposed movable wrist support, fixed wrist support and without wrist support when using a computer mouse. Eight subjects performed a standardized simple task set which has structured six detailed tasks with each wrist support option. The wrist angle variations in the right arm were registered by electrogoniometer and the muscle activity in the shoulder, deltoid and two extensors in the forearm were also registered by electromyography. The subjects rated perceived comfort while performing the tasks with each wrist support option. Working with proposed movable wrist support, compared to other options, gave significantly decreased wrist angle variations at almost tasks both biaxial movements. There is a decrease of 50% in wrist angle movements and 30% in EMG amplitude when compared a proposed wrist support with no wrist support. Also, in work with a proposed wrist support, the subjects rated more comfort but they showed a little decreased performance in a few detailed tasks.

This study examines the factors affecting 5G mobile communication market diffusion, especially focusing on the non-use intention of 5G based services. Consumer survey was conducted to gather data, and those are analyzed by using ordered logit model. Ultra High Definition (UHD) resolution, connected car, and Internet of Things (IoT) for home use are selected as a promising 5G services and are attributed as high speed, ultra low latency, and hyper-connection respectively. Our analysis result shows that lack of needs and high price are primary factors of non-use intention. While reliability issue is not significant in UHD, it is the most influential factor to connected car and IoT. Moreover, lower perception affects to non-use intention for each service. On the contrary, more experience in UHD and IoT affects to non-use intention.
