  • The purpose of this study is that we regard the notion of reality that television viewers feel as presence, point out problem of measurement tool that appropriate for TV, clarify the subordinate concept of presence, and develop measurement tool that have reliability and validity. To achieve this, we paid attention to reality of television as a determinant of presence and tried to elicit proper subcategories. That is, we progressed two steps research that distinguished external characteristic and content of the media into sensible reality and cognitive reality, and develop measure item and verified statistical validity. We analyzed the second research result about measurement category of presence selected by first research and then we did Exploratory factor analysis and Confirmatory factor analysis. As a result, the first characteristic that make people experience presence is sensible reality, that is, it is the factor of sensible faithfullness, image faithfullness, and image reality as the form factor of the media. The second characteristic is cognitive reality. That is the factor of social reality, relational reality, and practical reality as the factor of media content. Synthesizing these subordinate factor, we can conceptualize presence experience as a reality of media form and content in HDTV viewing environment.

  • 전세계는 $CO_2$ 규제강화와 에너지의 효율적 사용에 대한 사회적, 경제적 요구가 증대되면서 친환경 에너지 설비와 지능형 전력망(smart grid)가 크게 예상되고 있다. 이에 따라 기존 내연기관에 근거한 발전산업 및 자동차 산업은 필연적으로 청정에너지 기반의 전기에너지로 점진적으로 대체될 것으로 판단된다. 따라서, 청정 발전 시스템의 보급 확대와 기존 에너지의 효율적 사용을 위해서 2차전지 기반의 전력저장 기술과 연료전지 기반의 분산발전 기술이 향후 미래에너지 산업의 근간이 되는 중요한 기술들로 부상하게 되었다. 아연/공기전지는 현재는 연료전지 개념의 1차전지에 기술수준이 머물러 있지만 향후 미래에는 기존의 리튬이온전지의 낮은 에너지밀도를 극복할 수 있는 미래 2차전지 기술의 하나로 평가받고 있다. 본 연구에서는 이러한 연료전지 개념의 아연/공기전지에 대하여 기존의 수소연료전지 기반의 분산발전 분야에 적용한다면 약 1/10 이하의 가격으로 조기에 시장진입이 가능할 것으로 판단하여 사전 타당성 연구 및 대면적화를 위한 기초 설계인자 연구를 수행하였다. 연구결과, 소형 단전지부터 약 800cm2까지의 대면적 단전지까지 대면적화를 위한 기초연구를 실시하였으며, 4개의 cell로 구성된 최고출력 90W급 전해질 순환형 미니스택 시스템을 구성하여 발전시스템으로서의 가능성과 문제점 등을 도출하였다. 이러한 시험결과를 바탕으로 25개의 cell로 구성된 약 1kW 급 스택을 설계하여 향후 소형 발전시스템을 제작하고자 하였다.

  • A modeling and simulation program for an environmental control system (ECS) of a pod installed under wings of an aircraft was developed in order to estimate the system‘s performance during a flight. First, through the system configuration analysis in the main operational condition of the aircraft system, an ECS configuration adopting an air cycle machine (ACM) was selected. Therefore the modeling program was developed to simulate the ECS with an ACM. Second, the sensitivity analyses on performance variation of main components were conducted to complete the conceptual design of the ECS. A design point for the system and its components was obtained through the analysis with the modeling and simulation program. The design point for the system and components was obtained through the analysis with the modeling and simulation program. Third, in order to study the feasibility of the ECS configuration, off-design performances of the ECS on various flight conditions, such as take off, maneuver, cruise and landing etc were estimated. Dynamic characteristics were analyzed by transient performance evaluations.

  • Integrating corporate culture in a merger enterprise is considered as one of the most important variables to decide M&A success. This study established a conceptional model according to the preceding study on integrating corporate culture and organizational effectiveness, and formulated a hypothesis on the interrelation between a seven factors of corporate culture proposed by Pascale & Athos and Peters & Waterman and organizational effectiveness. The result of applying multi-regression analysis to test the hypothesis is as follows; firstly, all of a merger enterprise's cultural factors have meaningful influence on job involvement among organizational effectiveness; secondly, all of them have sincere influence on job satisfaction among organizational effectiveness except shared value; and thirdly, all of them except skill have significant influence on organizational harmony among organizational effectiveness. This is a significant empirical and exploratory study to ascertain the variables of corporate culture factors, and to verify their effects on organizational effectiveness.

  • The purpose of this study is to develop the Leisure Obsession Scale and examine the validity of the scale. The Leisure Obsession Scale was developed and identified its validity by exploratory factor analysis, confirmatory factor analysis, and correlation analysis. The Leisure Obsession Scale consists of two factors, which are 'Leisure Preoccupation' and 'Leisure Stereotype'. Those two factors indicated the reasonable fit index by confirmatory factor analysis. In addition, this scale displayed discriminant validity via measurement of obsession, workaholism, leisure anxiety, and leisure constraint. Also, the results of criterion validation analysis shows that the Leisure Obsession Scale and its subscale are correlated with measure of age, leisure information searching, intention of participation to new leisure activities, and intention of increase in leisure time. Conceptualizing leisure obsession and exploring components of leisure obsession would be valuable for understanding the nature of leisure obsession and its effects on leisure satisfaction, and suggesting more effective psychological intervention in a diverse population.

  • As a brand becomes a core asset in creating a corporation's value, brand marketing has become one of core strategies that corporations pursue. Recently, for customer relationship management, possession and consumption of goods were centered on brand for the management. Thus, management related to this matter was developed. The main reason of the increased interest on the relationship between the brand and the consumer is due to acquisition of individual consumers and development of relationship with those consumers. Along with the development of relationship, a corporation is able to establish long-term relationships. This has become a competitive advantage for the corporation. All of these processes became the strategic assets of corporations. The importance and the increase of interest of a brand have also become a big issue academically. Brand equity, brand extension, brand identity, brand relationship, and brand community are the results derived from the interest of a brand. More specifically, in marketing, the study of brands has been led to the study of factors related to building of powerful brands and the process of building the brand. Recently, studies concentrated primarily on the consumer-brand relationship. The reason is that brand loyalty can not explain the dynamic quality aspects of loyalty, the consumer-brand relationship building process, and especially interactions between the brands and the consumers. In the studies of consumer-brand relationship, a brand is not just limited to possession or consumption objectives, but rather conceptualized as partners. Most of the studies from the past concentrated on the results of qualitative analysis of consumer-brand relationship to show the depth and width of the performance of consumer-brand relationship. Studies in Korea have been the same. Recently, studies of consumer-brand relationship started to concentrate on quantitative analysis rather than qualitative analysis or even go further with quantitative analysis to show effecting factors of consumer-brand relationship. Studies of new quantitative approaches show the possibilities of using the results as a new concept of viewing consumer-brand relationship and possibilities of applying these new concepts on marketing. Studies of consumer-brand relationship with quantitative approach already exist, but none of them include sub-dimensions of consumer-brand relationship, which presents theoretical proofs for measurement. In other words, most studies add up or average out the sub-dimensions of consumer-brand relationship. However, to do these kind of studies, precondition of sub-dimensions being in identical constructs is necessary. Therefore, most of the studies from the past do not meet conditions of sub-dimensions being as one dimension construct. From this, we question the validity of past studies and their limits. The main purpose of this paper is to overcome the limits shown from the past studies by practical use of previous studies on sub-dimensions in a one-dimensional construct (Naver & Slater, 1990; Cronin & Taylor, 1992; Chang & Chen, 1998). In this study, two arbitrary groups were classified to evaluate reliability of the measurements and reliability analyses were pursued on each group. For convergent validity, correlations, Cronbach's, one-factor solution exploratory analysis were used. For discriminant validity correlation of consumer-brand relationship was compared with that of an involvement, which is a similar concept with consumer-based relationship. It also indicated dependent correlations by Cohen and Cohen (1975, p.35) and results showed that it was different constructs from 6 sub-dimensions of consumer-brand relationship. Through the results of studies mentioned above, we were able to finalize that sub-dimensions of consumer-brand relationship can viewed from one-dimensional constructs. This means that the one-dimensional construct of consumer-brand relationship can be viewed with reliability and validity. The result of this research is theoretically meaningful in that it assumes consumer-brand relationship in a one-dimensional construct and provides the basis of methodologies which are previously preformed. It is thought that this research also provides the possibility of new research on consumer-brand relationship in that it gives root to the fact that it is possible to manipulate one-dimensional constructs consisting of consumer-brand relationship. In the case of previous research on consumer-brand relationship, consumer-brand relationship is classified into several types on the basis of components consisting of consumer-brand relationship and a number of studies have been performed with priority given to the types. However, as we can possibly manipulate a one-dimensional construct through this research, it is expected that various studies which make the level or strength of consumer-brand relationship practical application of construct will be performed, and not research focused on separate types of consumer-brand relationship. Additionally, we have the theoretical basis of probability in which to manipulate the consumer-brand relationship with one-dimensional constructs. It is anticipated that studies using this construct, which is consumer-brand relationship, practical use of dependent variables, parameters, mediators, and so on, will be performed.
