Online games belong to a technology-oriented service industry that has emerged from the assimilation of game contents and communication networks in the respective realms of culture technology (CT) and information technology (IT). This study examines the individual acceptance of online games as entertainment-oriented technology based on the belief-attitude-intention paradigm and the underlying hedonic and utilitarian motivations. To measure the latent variables influencing the acceptance process, a structured questionnaire was developed based on the existing Technology Acceptance Model. Research model analysis and hypothesis testing were carried out using a structural equation model. Results indicated that latent variables reflecting hedonic and utilitarian characteristics had a significant influence on user behavior in the acceptance of online games. By uncovering the core factors in! fluencing the acceptance of online games and thereby theoretically verifying the latent variables influencing the acceptance of entertainment-oriented technology, this study provides strategic implications for business models by game companies aimed at attracting a large user base and dominating the market.

The objective of this study is to investigate factors influencing user's intention to use by expanding TAM(Technology Acceptance Model). Based on this model, this study developed a comprehensive model and user's motivation factors such as extrinsic and intrinsic motivation to describe their intention to accept WCDMA service. For this purpose those who have subscribed to and use the current mobile communication service - all of whom were 13 to 49 years old living in Seoul or other large cities - were surveyed. Structural equation model was conducted to identify and validate the relationship of overall variables relating to mobile service acceptance. The analysis results indicate that intrinsic motivations in mobile service acceptance process have significant impacts on perceived usefulness and perceived ease to use. The results of this study also proposed the way to boost mobile service user's extrinsic and intrinsic motivation for coming up with strategies on how to improve effectiveness of communication and marketing. Future directions and limitations are also discussed.

According to statistics, the number of mobile payment users in China shows an increasing trend year by year. However, less than half of people over 60 years old use mobile payment. The purpose of this study is to explore the reasons for the low usage rate of mobile payment platforms among the elderly in China. Through literature research, questionnaires and interviews, the author found that the main obstacle for the elderly in China to use mobile payment platforms is acceptance barrier. Then, the user experience research method and technology acceptance model (TAM) were combined to construct a new research model and five hypotheses affecting acceptance behavior in the model were summarized. Finally, the Analysis of Covariance(ANCOVA) was used to test the hypotheses and found that satisfaction (SA), perceived usefulness (PU) and job relevance (JR) had significant coefficients of 0.001, 0.000 and 0.004 respectively, all of which were less than 0.05 and therefore had a significant effect on acceptability. The other two elements, perceived ease of use (PE) and self-efficacy (SE), did not have a significant effect on acceptability. Ultimately, a new user experience acceptability model was constructed to provide theoretical support for mobile payment platform developers and designers to develop products from the acceptability perspective, so as to develop more mobile payment methods suitable for elderly users and improve the acceptance of mobile payment by the elderly.

Research related to hydrogen technology is being actively conducted around the world. Korea is also making great efforts to develop technology to leap forward as a hydrogen economy powerhouse. In particular, the world's No. 1 hydrogen vehicle penetration rate is proof of this. However, the construction of hydrogen refueling stations is being delayed. The biggest delay factor is the public opposition. As such, policies without public support cannot be successfully implemented and are not sustainable. Therefore, this study intends to analyze the factors affecting the acceptability of hydrogen refueling stations in favor of and against them. As a research method, the basic factors affecting acceptability were identified by reviewing previous studies, and a questionnaire was designed and investigated based on the established factors. The validity and reliability of the questionnaire were verified, and the hypothesis was verified through correlation analysis. And, using structural equation modeling, a factor model was developed on the acceptability of hydrogen refueling stations. As a result of the study, acceptability defined private acceptability and public acceptability. In the case of private acceptability, it was confirmed that the higher the attitude toward the environment, the higher the level of knowledge about the hydrogen charging station, and the lower the degree of feeling the risk of the hydrogen charging station, the higher the acceptability. In the case of public acceptability, it was confirmed that the higher the benefit, the better the attitude toward the environment, and the lower the risk-taking characteristics of the individual, the higher the acceptability. Therefore, in this study, based on the potential factors verified in previous studies, the main factors affecting the acceptance on hydrogen refueling stations were identified. And the acceptance model was developed using structural equation modeling. This study is expected to provide basic data to seek ways to improve the acceptance of public when implementing national policies such as hydrogen refueling stations, and to be used analysis data for scientific communication.

$\beta$-Sulfatoethylsulfone기를 갖는 일시적 수용성 반응성 분산염료는 분산제를 첨가하지 않고도 염욕내에서 단분자 상태를 유지할 수 있으며 염색 공정 중 온도와 pH조건의 변화에 따라 Scheme 1과 같이 비수용성 vinylsulfone form으로 변환된다[1]. 이 때 vinylsulfone기는 섬유와 화학결합을 할 수 있는 대표적인 반응기이므로 이 염료는 일시적 수용성 분사염료와 반응성 염료의 두 성질을 동시에 지닌다[2]. (중략)

UCC는 참여자들의 개인의 심리유형에 따라 참여정도가 좌우될 수 있다는 점에서 MBTI 기법을 통해 심리유형을 파악하여 TAM에 대한 UCC의 수용도를 파악하였다. 이를 위해 UCC를 활용하고 있는 광주, 전남.북 지역의 고등학생 및 대학생 244명을 분석한 결과 성격유형 중에서 외향형과 감각형이 UCC 수용에 영향을 미치는 것으로 나타났다.

1968년 ARPA 네트워크의 출현 이후 음성 서비스 위주의 네트워크와 데이터 서비스 위주의 네트워크는 서로의 서비스를 수용하기 위해 노력해왔다. 음성 기반의 네트워크에서 데이터를 수용하기 위한 노력은 ‘꿈의 망’으로 그친 ISDN(Integrated Services Digital Network)으로 나타났고, 데이터 기반의 네트워크에서 음성을 수용하기 위한 노력은 보편적인 비연결형 데이터 서비스와는 대비되는 B-ISDN(Broadband-ISDN)으로 나타났다. 이후 다시 B-ISDN은 IP 서비스의 수용을 위해 ATM 교환기를 MPLS(Multi Protocol Label Switching) 교환기로 대치하여 보완하고 있지만, VoIP(Voice over IP)등 음성서비스의 제공에는 아직 완전한 해법이 제시되지 못하고 있다.(중략)

최근 텔레비전 드라마의 소재와 내용이 다양해지면서 드라마 속의 젠더(gender)의 표현 역시 다양화 되고 있다. 기존의 성에 대한 고정관념을 깨는 다양한 젠더 문제가 제시되고 있는 현 시점에서, 사회적 이데올로기를 반영하고 재생산하는 데 있어 중심적 역할을 하고 있는 방송 드라마의 이러한 변화에 대하여 시청자는 어떠한 수용 태도를 보이고 있는지, 특히 젠더 문제의 중심에 있는 남, 녀 성별 수용 태도는 어떤 차이를 보이는지를 비교 분석함으로써, 방송 드라마의 수용에 대한 젠더 역학을 고찰하고자 한다.
