오늘날 실감미디어 산업이 고부가가치 산업으로 집중을 받고 있으며, 몰입감과 실제감, 현장감을 높임으로 다양한 산업에 적용되고 있다. 그러나 실감미디어(Realistic Media)와 관련된 연구는 기술개발과 산업동향, 전망에 관한 연구가 주를 이루고 있으며 서비스나 비즈니스모델, 수용의도에 관한 연구는 부족한 실정이다. 이에 본 연구는 실감미디어서비스의 사용자 수용과 사용의도에 관한 연구를 수행하였고, 이를 위하여 확장된 기술수용모델인 UTAUT(Unified Theory of Acceptance and Use of Technology) 모델과 인지된 신뢰성, 그리고 실감미디어서비스의 인지된 만족도를 적용하여 실증적 연구를 수행하였다. UTAUT모델은 새로운 정보기술을 수용하는 사용자들의 의도를 파악하는 모형으로 TAM(Technology Acceptance Model)의 발전된 형태이며, 다양한 분야에서 개인수준과 조직수준의 연구에 적용되어왔다. 실감미디어서비스의 수용 및 만족요인을 위하여 성과기대, 노력기대, 사회적 영향을 채택하고, 양뱡향서비스의 수용에 필수적이라 생각되는 인지된 신뢰성을 사용하여 연구를 진행하였다. 본 연구는 UTAUT모델의 선행요인과 인지된 신뢰성이 실감미디어서비스의 인지된 만족과 수용의도 간에 어떠한 관계가 있는지 검증하였으며, 실감미디어서비스 분야의 만족과 수용의도에 관한 향후 연구에 다양한 설명변수가 사용될 수 있다는 점을 확인 할 수 있었다는 시사점을 제시하였다고 판단된다.

Internet has begun various transformation and innovation in terms of society, culture, and industry. Today, Social Network Service (SNS) is exceedingly popular and useful tool for making human relationship. Previous studies related to SNS were focused on user acceptance of new technology, based on Technology Acceptance Model (TAM). However, they had a limitation to focus on technology acceptance, without the consideration of personal and behavioral factors in SNS use. So, this study considered communication and self-efficacy as independent variables, and this study also adopted information and knowledge sharing, and perceived enjoyment as mediating variables. The purpose of this study is to investigate the structured relationship between personal, behavioral factors, and continuous intention to use of SNS using utilitarian and hedonic value. This study conducted survey through e-mail, direct mail, and interview with SNS users. Empirical analyses based on 205 respondents were conducted in order to test the hypotheses. The result of hypotheses testing showed that communication and self-efficacy have the positive impact to information and knowledge sharing, and perceived enjoyment, also, perceived enjoyment has the positive impact on continuous intention to use of SNS. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategy for acquiring and retaining long-term customers related to SNS business.

The present study is PSD(power spectral density) profile for BSR(buzz, squeak and rattle) evaluation of automotive parts and modules. Road data for made PSD profile is measured using the PG(proving ground) conditions. PSD profiles for BSR noise detection of major automotive part/modules are developed using the professional program. To evaluate the prepared PSD profiles for individual modules : seats and seat belt retractors. The test method for evaluating PSD profiles was random excitation using multi-axis BSR excitation system of AMPRIC(Advanced Motor Parts Regional Innovation Center). In this work, Selected PSD profiles were performed to evaluate total RMS(root mean square) levels and dB(A)(dB SPL, A weighted) levels through comparing and analyzing test results.

Purpose: The scale of a market of mobile payment which was insignificant is explosively being improved by development of various communications technology and achieving rapid diffusion of smart phone. According to this phenomenon, new method of financial dealings through a mobile can be seen as a new paradigm that leads to a change of existing payment work and also recognized as an innovation of information technology. Methods: but a study regarding whether the use of mobile payment service takes an important role as an influencial factor is still insufficient. This study was based on the model of innovation resistance by Ram(1987) and established a hypothesis and a model to confirm how four factors (usability, security, economic feasibility, responsiveness) influence to innovation resistance and the intention of discontinuous use. Results: usability, security were found to be significant predictor variables of innovation resistance to use mobile payment system, but economic feasibility, responsiveness were not found to be significant predictor variables. Conclusion: Providing gave a theoretical foundation for future research in that it presents the variables to consider new forms of mobile payment services, the mobile payment services will need to show a differentiated strategy and traditional marketing strategy.

대학〈글쓰기〉교과 운영 실태와 개선방안 - 전남대의 경우를 중심으로

  This is designed to analyze about the matter of college 〈Writing〉 the whole managements, to offer the improvements on the basis of it. Chonnam University is chosen as an object of analysis. The reason for that is as follow. First, Chonnam University is the one of the leading educational intention in Kwangju and Chonnam. Second, it will be able to get an implication about how it is made, how it is intended and what contents are made.<BR>  It was confirmed that how the management of college 〈Writing〉 curriculum was made and what intention it had through the works. However, it was confirmed that it was also needed a serious worry and practice that everybody could feel sympathy about the 〈Writing〉 curriculum identify and the educational purpose through this work. The matters of being analyzed and the plan offering through this work is as following.<BR>  First, it was confirmed that the matter of non-professionalism of the teacher who con take full charge of 〈Writing〉 for the system and the matters of the poor educational infrastructure. To improve these matters, it is needed to get a specialty researcher and special teacher without delay. Also, with an alternative plan which is possible in short term, it was pointed out ‘the better teaching(더나가)’ meeting"s efficient management and support, active use of e-learning system.<BR>  Second, for the teaching materials, it was pointed out as matters that the writing leadership theory of problem solving course centered didn"t carry their point definitely and the writing teaching-learning of self-leading wasn"t made. To improve these matters, it was suggested that by adjusting the management direction of teacher"s workship, trying to convert realistic teaching-learning strategy into social-constructionist writing principle and strategy.<BR>  Third, for the teaching-learning, it was confirmed that it wasn"t prepared completely teacher"s role and teaching model in the classroom, and evaluation instrument and method. To solve these problem, it was suggested teaching-model and evaluation principle following social-constructionist principle as an alternative.<BR>  It is expected to show an implication for the efficient college writing subject management through this analysis and improvement.

As the convergence technology by ICT(Information and Communication Technology), is widely spread out, inter-industry convergence activities, according to user"s needs and market demand, are being activated between products, between products and services, and between technology and technology. Most companies need to develop a convergence capability to cope with convergent environment changes. Specifically, they are recognizing the importance of convergence performance through ICT competence and convergence capabilities. Developing organization"s convergence capability with ICT competence provides an important opportunity to improve convergence performance. The purpose of this study is to identify the relationship between ICT competence and convergence performance, and the mediating effect of convergence capabilities. Results of data analysis showed that companies need to consider the improvement of convergence performance through the development of convergence capability, rather than direct effect between ICT competence and convergence performance. This study complements the limitations of the existing theory of dynamic capabilities and suggests the implication to provide new insights for sustainable growth through the development of convergence capability.

100 MWe 순산소 석탄연소 발전시스템의 개념설계-영동 프로젝트

최상민(Sangmin Choi) 한국연소학회 2012 한국연소학회지 Vol.17 No.3

An existing unit of power plant is considered to refurbish it for possible application of carbon capture and storage(CCS). Conceptual design of the plant includes basic considerations on the national and international situation of energy use, environmental concerns, required budget, and time schedule as well as the engineering concept of the plant. While major equipment of the recently upgraded power plant is going to be reused, a new boiler for air-oxy fired dual mode operation is to be designed. Cryogenic air separation unit is considered for optimized capacity, and combustion system accommodates flue gas recirculation with multiple cleaning and humidity removal units. The flue gas is purified for carbon dioxide separation and treatment. This paper presents the background of the project, participants, and industrial background. Proposed concept of the plant operation is discussed for the possible considerations on the engineering designs.
