This study is to analyze the differences of consumer preferences between the terrestrial DMB and satellite DMB in various segment groups by using survey data. We categorized the consumers by the DMB preference patterns into four groups, i.e., non users group, terrestrial only users group, satellite only users group, dual users group. And then we analyzed the differences among these four segment groups in demographic characteristics, behavior patterns on telecommunication and broadcasting services, life-style, attitudes to DMB services.

Convergence products, which perform multiple functions, are gaining popularity in the marketplace these days. Unfortunately, however, little research to date has been conducted as to how consumers evaluate such products. The present research, based on the existing literature regarding the innovation resistance and product bundling, examines the factors influencing consumer responses to convergence products. The results of the study reveal that consumer evaluations and purchase intentions are affected by consumer perceptions of risk (emotional and functional), convenience, product complementarity and relative advantage as well as consumer individual differences measured by technographics. Implications of the results for marketers and future research are discussed.

BPR(Business Process Re-engineering)은 업무 프로세스를 혁신적으로 재설계 함으로써 급속한 외부환경과 내부환경의 변화에 능동적으로 대처하고자 하는 기업의 경영혁신 기법, 조직 재설계의 수단으로 도입되었다. 해마다 시행되고 있는 정보화평가위원회의 국가 정보화 사업에 대한 평가는 정보화 사업의 성과관리에 있어 BPR에 따른 조직과 제도개선 성과를 포함하여 제도혁신에 대한 인센티브 제공 둥 조직과 제도혁신 강화의 필요성이 강하게 주장되는 등 BPR은 공공부문으로 점차 확대 될 추세이다. 본 연구는 조직적 문제의 해결을 통하여 지방자치단체 GIS의 효율성을 제고 하고자 하는 목적으로 출발하였다. 따라서 BPR의 이론적 고찰을 통하여 지자체 GIS BPR의 개념을 정의하고, 지방자치단체의 GIS 시스템 도입 이후의 업무 프로세스의 변화, 업무 변화의 양상, 잠재적 업무 효과를 BPR의 기법을 통해 보여줌으로써 조직 재설계의 수단으로 GIS BPR의 가능성을 모색하였다. 이는 GIS 발달 단계에 따른 효과 창출의 패러다임을 고려한 지방자치단체 GIS 업무의 변화를 수용하는 능동적이고 융통성 있는 조직 모형을 찾는 것이라 할 수 있다. 따라서 단위조직, 진화조직, 전체조직의 GIS 발달 단계에 따른 지방자치단체 GIS 조직 모형을 규정하였다. 본 연구를 통한 시사점은 지방자치단체 GIS 조직이 현재의 단위조직 수준에서 진화조직의 단계를 걸쳐 전체조직으로 향하는 가능성을 제시했다는 점이다. 이는 지방자치단체가 각각의 단계에서 GIS의 도입 효과를 창출하기 위하여 충실히 수행해 할 것이 무엇인지를 BPR을 통해 조직적 차원에서, 그리고 조직이 다루는 업무영역의 차원에서 접근했다는 점에서 그 의의가 있다. 본 연구의 결과를 통해 지방자치단체 GIS 기본계획에 있어 조직 측면의 장기적 비전의 제시가 가능하며 이를 통해 보다 성숙된 GIS 사업의 추진과 효율적인 시스템의 운영이 가능할 것이다.. 이상의 결과를 종합해볼 때, ${\beta}$-glucan은 고용량일 때 직접적으로 또는 $IFN-{\gamma}$ 존재시에는 저용량에서도 복강 큰 포식세로를 활성화시킬 뿐 아니라, 탐식효율도 높임으로써 면역기능을 증진 시키는 것으로 나타났고, 그 효과는 crude ${\beta}$-glucan의 추출조건에 따라 달라지는 것을 알 수 있었다.eveloped.

The constitutive model relating the surface force and the deformation of bundle was introduced by considering a representative prodedure that stands for the bundle movement. Then a fundamental equations system could be simplified considering a steady state of the process. On the basis of the simplified model, the simulation was performed and the results could be confirmed by the experiments under various conditions.뢰, 결속 등 다차원의 개념에 대한 심도 깊은 연구와 최근 제기되고 있는 이론의 확대도 필요하다. 마지막으로 신뢰와 결속에 영향을 미치는 요소간의 개념적 분류, 차이의 검증, 영향력 등

To enhance the efficiency of national R&D programs, it is the most important thing to establish the optimized evaluation system. This is because the distorted evaluation could be an obstacle to select the best suited research team and lead the desirable research result. In current evaluation process of national R&D program, it is the most frequently used method for eliminating an evaluator's biased view to exclude both the maximum and minimum scores. However, there are several limitations in this stereotype method. Therefore, this study analyzes some real cases to derive the problems from the stereotype method and then recommends the complementary alternatives which can enhance the reliability of the evaluation system for national R&D programs. The results acquired from this study seem to be helpful to increase the agreement of the applicants on the evaluation results and ultimately to maximize the efficiency of national R&D program. In addition, they can be applied to various field with respect to the methodology for ranking decision.

Today, a web site is used as a strategic method to fulfill a company's objectives. In particular, a web site provides a service for customers to find satisfaction in visiting family restaurants, and it recently has helped to attract the interest of a variety of customers. Currently, companies that manage family restaurants operate their Web sites as strategic tools and use them to perform public relations and marketing of their restaurants. This effort influences management and helps to improve the business and profitability of family restaurants. The research model of this study is an expansion of the Technology Acceptance Model (TAM) and examines whether ease of use and usefulness of family restaurant web sites influence the relationship of intention to use, actual use, and recommendation to use by gender. The results of this research would suggest that web sites are useful in establishing a marketing strategy for companies that operate family restaurants.

Using the extended technology acceptance model (TAM), the study aimed to understand consumers' adoption process for smart fashion products. The research model was designed to examine the impacts of perceived ease of use and usefulness on attitude and behavior intention toward smart fashion products based on the technology innovativeness, enjoyment, and subjective norm variables. An online survey was conducted on consumers by employing a marketing research company. A total of 230 useable responses were obtained. Confirmatory Factor Analysis (CFA) was performed to test the measurement model. The proposed hypotheses were tested by employing the Structural Equation Model (SEM). The results found a positive impact of perceived ease of use on usefulness and a positive influence of usefulness on attitude and behavior intention. Attitude had a positive effect on behavior intention. In addition, technology innovativeness was found to have a positive influence on perceived ease of use and enjoyment had a positive influence on usefulness and attitude. Subjective norm predicted behavior intention. The findings of the study contribute to smart fashion literature and have important implications for smart fashion product developers and marketers, as they offer insights into the important role of technology innovativeness, enjoyment, and subjective norms perceived by consumers in improving attitudes and behavior intentions toward the products. Limitations and future research directions are discussed.

While Korea became one of manufacturing powers in the world through a fast-follower strategy as well as implementing the approach of advancing manufacturing business focused on quantitative input, The advent of the fourth industrial revolution and demand becoming more complicated than ever both require a system that quickly detects the change of markets in advance and reflects it in the manufacturing strategy. Accordingly, the introduction of a smart factory is not optional but mandatory in order to strengthen the competitiveness of manufacturing business using ICT. This paper aims to investigate key factors having influence on the intention to continuously use a smart factory, the innovative IT device, on the basis of the technology acceptance model. This paper analyzed the influence of the leadership of CEO, organizational learning and perceived switching costs on the intention to continuously use a smart factory by the parameters of perceived ease of use and usefulness, the major belief valuables of the IT acceptance model.

This study analyzed the effect of technology preparation and technology acceptance factors on the intention of public library librarians to use artificial intelligence-based technology using the technology acceptance model. To this end, a survey was conducted on public library librarians, and a total of 202 survey data were used for statistical analysis. As a result of the hypothesis test, first, optimism has a significant positive (+) effect on perceived usefulness, and discomfort has a significant negative (-) effect. Optimism and innovation on perceived ease of use were found to have a significant positive (+) effect, and discomfort was found to have a significant negative (-) effect. Second, perceived ease of use was found to have a significant positive (+) effect on perceived usefulness, and both perceived usefulness and perceived ease of use had a significant positive (+) effect on the intention to use. Third, optimism was found to have a significant positive (+) effect on the intention to use, and anxiety was found to have a significant negative (-) effect. This study is expected to provide basic data on the use of artificial intelligence technology in the future by empirically analyzing public library librarians' perceptions of artificial intelligence-based technology.
