본고에서는 미래인터넷 환경으로서 사람 사물 공간 간의 새로운 관계망으로서의 만물지능통신 기반 초연결 네트워크(All Things on Ambient Network: ATAN)에 주목한다. ATAN은 네트워크를 구성하는 행위 주체로서 인간과 인간의 소통에서 인간과 사물, 사물과 사물, 공간과 공간으로 확장되어 데이터, 정보 그리고 행동을 초연결하는 시스템의 총체로 본다. 본고에서는 ATAN이 포스트 스마트 사회 인프라로 이행하는 기여 지점에서 인간과 비인간의 의사소통 티핑 포인트(tipping point)로서의 ATAN 싱귤래리티(singularity) 개념이 존재함을 제안한다. 이러한 전제하에서 ATAN 싱귤래리티의 발생 구도를 설정하고, 웹의 과거 현재 미래 고찰을 통해 ATAN 패러다임으로 전개되는 과정을 고찰한다. 또한 주요국의 미래인터넷 전략 분석을 통하여 ATAN으로의 공통 지향성을 추출한다. 이러한 작업을 통해 우리나라의 미래 네트워크의 전략적 콘셉트로서 ATAN 국가전략기조를 제시한다. 마지막으로 첨단 네트워크 기술이 사회변형을 촉진하고 사회가 기술을 인간 중심으로 수용하는 건강한 기술사회 복합체(technology-social complex)를 지향할 것을 강조하였다.

Smart TV is expected to take the center stage of the recent "smartization" trend in IT and consumer electronics as it performs a hub for various smart IT devices, such as smart phone, smart pad, PC, etc. It is distinct from traditional TVs or even IPTVs in the sense that it provides immersive and interactive experiences via apps downloaded through TV app store. Smart TV could serve as a new intermediary device between other smart devices and the Internet. While it started experiencing a rapid growth, little research has been conducted to understand this emerging technology in terms of its user acceptance and adoption by users. The current research attempts to fill the gap in the field by examining factors and processes for this new technology to be adopted by users. This paper draws on theories of IT acceptance and use, such as the "Unified Theory of Acceptance and Use of Technology", to investigate factors affecting "intention to use" of smart TV. The proposed research model is analyzed using the structural equation modeling approach. Findings show that such factors as innovativeness, switching cost, switching benefit, service interface, and user interface affect users' intention to use smart TV, through effort expectation, performance expectation, and social influence. Theoretical and managerial implications are discussed.

How will the field of education react to the big data craze that has recently seeped into every aspect of society? To search for ways to use big data in mathematics education, this study first examined the concept of big data and examples of its application, and then pursued directions for future research in two ways. First, changes in the representation and acceptance of data are required because of changes in technology and the environment. In other words, the learning content and methodology of data treatment need to be changed by describing a myriad amount of data visually or by 'analyzing and inferring' data to provide data efficiently and clearly. Additionally, the mathematics education field needs to foster changes in curricula to facilitate the improvement of students' learning capacity in the 21st century. Second, it is necessary to more actively collect data on general education and not merely on teaching or learning to identify new information, pursue positive changes in the teaching and learning of mathematics, and stimulate interest and research in the field so that it can be used to make policy decisions regarding mathematics education.

There are 27 science education institutes for gifted education institutes in the university with support from the MSIT (Ministry of Science and ICT). Mathematics, physics, chemistry, biology, earth sciences, and information classes are given in each science education institute for the gifted. The authors developed a curriculum with components of computing thinking for information-gifted students. To determine if the curriculum is effective on the computer scientific attitude of the information gifted, TOSRA was modified and the test was then developed. Information students were educated at K university's science education institute for the gifted with the developed curriculum for one year and the computer scientific attitude of them was tested. According to the test results, there was a significant difference in the computer scientific attitude of the curriculum conducted at the institute at 0.05 level of significance. Statistically significant differences were observed in the social implications of computer science, attitudes of computer scientific inquiry, and the normality of computer technicians at the level of significance of 0.05. On the other hand, there were no significant differences in the adoption of computer scientific attitudes, the enjoyment of computer science lessons, leisure interest in computer science, and career interest in computer science.

This study investigated the consumer acceptance process of the fourth industrial revolution new product to be introduced into the market in the future. The 4th Industrial Revolution new products are technological advances compared to the existing ones. The technology acceptance model that was used in the past has been modified to reflect variables like the social effects of the 4th Industrial Revolution, expected experience, and perceived risk. Modified models were proposed and verified. Six representative new products of the 4th Industrial Revolution were selected and examined by 40 respondents, and the hypotheses were verified using programs such as SPSS and AMOS. And conclusions and implications are as follows. First, the innovativeness of the fourth industrial revolution new products influences positive evaluation factors such as expected experience and perceived usefulness and it also affect positively to the perceived risk. In addition, the expected experience of the fourth industrial revolution new products has a great effect on the perceived usefulness and social influence, but it didn't affect to the perceived risk. Like the results of the TAM model, purchase intention of the fourth industrial revolution new products are strongly influenced by perceived usefulness. Finally, the perceived risk of the new product of the 4th Industrial Revolution had no statistically significant effect on the purchase intention, and the social influence of the 4th Industrial Revolution had a significant effect on the purchase intention. In general, respondents are highly aware of the social impact of the Fourth Industrial Revolution and seem to be very positive in this respect.

An analysis was carried out for this study to figure out if there exists any differences in the model consumers accept for commercialized MP3-playing clothing and bio-signal sensing clothing. To analyze the differences of the structural variables of the products types, t-test was conducted with SPSS 15.0 package and multi-group analysis with AMOS 5.0 to find out the differences of each path goes with product types in structural equation model. In analytical results of effective sample of 557 copies of questionnaire, consumers' were highly aware of MP3-playing clothing in perceived ease of use, while they were aware relatively high of bio-signal sensing clothing in perceived usefulness, attitudes, consumer acceptance. The perceived value which was input to find out consumers awareness about sale price of commercialized products, was proven to do very important moderating role in forming consumers' attitudes and acceptance intention. Besides, consumers showed a difference in path in accepting model goes with product types. In bio-signal sensing clothing case, 'the perceived usefulness$\rightarrow$attitudes' path which was backed up in MP3-playing clothing was rejected, and 'perceived value$\rightarrow$attitudes' path appeared relatively high with moderating role of perceived value higher than MP3-playing clothing. Considering the results above, as the smart clothing is in the initiative commercialization stage while consumers were in the inquiry stage into awareness or information necessary in the course of purchase decision-making, and so an effective commercialization strategy seems to be necessary.
