Using the TAM, this study investigates the impact of Perceived Usefulness(PU), Perceived Ease of Use(PEOU) of the Animal-Crossing users on game satisfaction(DOS), immersion(DOI), and the relationship between user's attitude and intention through the google online survey. The decorative elements of the game generate a healing effect and more than half of the survey participants share game activities with the online community in terms of PU. In the case of PEOU, the survey participants positively evaluate the technological advancement such as graphics and sounds of the game. In addition, both high degree of satisfaction and immersion in the game have significant correlations with the intention for replaying the game and intention for recommending the game to others.

Using the extended technology acceptance model, this study aims to quantitatively analyze the user experience with the . In the case of Perceived Usefulness and Perceived Ease of Use, only limited detailed factors have significant impacts on the degree of satisfaction. The degree of satisfaction has positive correlations with the degree of immersion and the variables of Behavioral Intention to Use Metaverse. Although sophisticatedly remediates using digital technology to provide visitors with the sameness of exhibits, exhibition circulation and interaction method, the metaverse exhibition does not acquire the same value of the exhibition. In conclusion, cannot replace , however, it has the potential to offer learning usefulness to visitors with low accessibility to the art museum.

The purpose of this paper is to provide values and effectiveness to libraries making a new social network service marketing model and strategy. According to study, when libraries entice library users with social network services, the users become loyal customers who give libraries long-term supports. For method of study, it establishes 15 hypotheses and proves those hypotheses with 157 responders. After inspecting hypotheses, 13 hypotheses are adopted and 3 hypotheses are dismissed. During the research, it is verified that usefulness perceived by library users is the most important factor of user satisfaction and continuous use intention which increased library users' intention to continue visiting the library. In addition, effectivness of marketing and cause are found in order of system quality, information quality, reliability, interactivity, subjective norms. In other words, the study found that library users found their information for using social network services and this attribute affects user satisfaction and ultimately continuous use intention in a positive way.

This study used a learner acceptance model to investigate the effect of SNS characteristics on user satisfaction and visit intention. A structured self - report questionnaire was administered to 172 college students. Structural equation modeling was applied using SPSS 18.0 and AMOS 22.0. The results of this study are as follows: First of all, the usefulness of informativeness did not affect the usability of the extracted SNS characteristics, and the usability did not affect usability. (+) Influence of. The characteristics of SNS can be utilized as a marketing tool to increase customer 's use and influence the customer' s intention to visit and further to create customers. In the future, various age groups will have to be surveyed. By examining the correlation between the degree of food companies' involvement in SNS and consumer visits, one can see how SNS activities of restaurant companies affect marketing activities.

Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

Gartner's Hype Cycle model is widely used to describe technology maturity, acceptability, and commercialization. In the Hype Cycle model, the techniques go through five stages, those are Innovation Trigger(first stage), stage Peak of Inflated Expectations(second stage), Trough of Disillusionment(third stage), Slope of Enlightenment(fourth stage) and Plateau of Productivity(fifth stage). In many studies, Hype Cycle is widely used as a basis for future prediction of technology, but the verification is somewhat lacking. In this paper, we analyzed the technologies that appeared in the Hype Cycle for the emerging technologies from 1995 to 2017. Through this, we found technologies that appeared as non first stage when first appearing, and techniques that showed a reversal of the maturity stage. In addition, we found that none of the technologies from 1995 to 2017 had gone through stages 1-5.

Today, Software as a Service(SaaS) is being recognized as a key means to enable the innovation of software distribution. Despite the increase in the interest in SaaS, individuals as well as businesses are not yet making an extensive use of it. This research is aimed at identifying and analyzing the antecedents of intentions to use SaaS. We proposed a research model to predict an individual's intention to use SaaS based on the Technology Acceptance Model(TAM). To this end, we conducted a questionnaire survey in which actual software users participated. An empirical analysis has been performed to test the reliability and validity and the hypotheses using SPSS and AMOS software packages. The results of the analysis revealed that functionality, interoperability and economic benefits have positive effects on the intention to use SaaS, while system quality has no significant effect on the behavioral intention. We discussed practical as well as academic implications, and provided research directions.

한강은 서울 지역을 관통하고 있다는 점에서 수도권의 수자원 이용과 폐수 수용체로서의 한강의 역할이 실로 막대하다. 이런 맥락에서 한강에서의 수질오염문제는 주요한 사회경제적 문제 중의 하나로 부각되고 있다. 한강 수질 악화를 방지하기 위한 관리 방안이 이미 시행중에 있으나 여전히 한강 수질 오염은 문제로 남아 있는 실정이다. 이를 감안하여 보다 나은 관리책에 대한 요구에 부응하기 위하여 본 논문은 기존의 수질기준을 최소비용으로 달성하는 비용 효과적인 방식을 시스템 최적화 분석 기법에 접목하는 모델을 구축하고 있다. 이 모델은 우리 나라에 두드러진 수문학적 특징, 즉 자정능력상의 계절적 차이가 지역적 특성과 오염 처리 기술상의 다양함, 그리고 기존의 법적 제도적 특정들과 어떻게 연결되어 얼마나 처리 비용상의 절약을 유도해 낼 수 있는지에 관한 정책정보를 제공해 줄 수 있게 고안되었다. 연구의 결과치에 의하면, 표적 지천상의 지역적 안배와 처리 공정상의 기술-비용적 차이를 고려하고 비갈수기에 처리시설을 신축적으로 운영할 경우 한강 수계에서 BOD 부하량 삭감비용은 상당한 정도( 예로, 1992년 물가수준에서 매일 3,000만 원 이상) 절감 가능한 것으로 나타나고 있다.

최근 무선랜 기술이 타 무선솔루션에 비해 비용이 저렴하고 사용하기 쉽다는 장점으로 큰 인기를 끌면서 급속히 확산되고 있다. 무선랜은 캠퍼스 크기의 서비스 지역에서 다양한 인터넷 서비스를 제공하는 기본 인프라로 사용하기에는 적당하나 아직 인증이나 트래픽 제어에 관한 많은 부분에서 개선할 필요가 있다. 기본적으로 무선 서비스 망은 유선 망과의 연동을 위해서 게이트웨이 기반 모델을 사용한다. 본 논문은 유, 무선을 연결하는 게이트웨이 기반의 사용자 인중 및 트래픽 제어를 제공하는 시스템을 구현하여 현재의 무선망에서의 차등화된 QoS 네트워크 서비스를 제공하였다. 구현한 게이트웨이는 향후 다양한 서비스 모델을 수용 할 수 있도록 확장성을 제공한다.

인터넷과 WWW는 전통적인 비즈니스 모델에 혁신적인 변화를 가져왔고, 인터넷/인트라넷 기반의 전자적 서비스를 통해 비즈니스 거래를 가능케 하는 e-commerce를 거쳐 보다 확대된 비즈니스 개념과 모델을 제공하는 e-business 라는 새로운 환경을 만들어냈다. 따라서 현재 사용자의 요구를 보다 빠르고 정확하게 수용하여 원하는 서비스를 제공하는 e-business 컴포넌트들이 많이 개발되고 있으나 서로 다른 플랫폼이나 환경에서 개발된 e-business 컴포넌트의 통합과 운영에 한계가 있어 실제 컴포넌트 기술의 적용을 통한 효과를 기대하기 어려운 실정이다. 따라서 본 논문에서는 다양한 플랫폼과 환경에서 새롭게 개발되는 e-business 컴포넌트들의 조립과 기존의 e-business 컴포넌트 재사용의 가치를 극대화기기 위해 표준적인 접근인 MDA(Model-Driven Architecture)를 기반으로한 e-business 컴포넌트 개발을 위한 프로세스를 제안하고, 사례연구를 통해 적용하고자 한다.
