This paper Is concerned with a new techno-economic model Ing of ATM based h19h-speed networks. Coupled with advances of technology, the rapid development of new telecommunication services significantly increases the magnitude of risk in making an Investment decision. Naturally, the success of techno-economic modeling depends on how effectively we manage underlying risk factors such as cost and technology To deal with risk factors, we need to rely on modern decision and risk analysis while Implementing mathematical optimization for solving a complex capacity expansion problem of telecommunication systems during the planning period. We provide a case study that will enhance our understanding of the techno-economic analysis for emerging telecommunication systems.

기술진화가 특정 산업 및 전체 국민경제에 미치는 영향은 지대한 것으로 보고되고 있다. 본 연구는 이러한 연구경향을 반영하여, 기술진화(techno evolution)가 정보통신산업(IT)에 어떤 영향을 미치는지에 대하여 연구하였다. 이러한 목적을 위하여 정보통신산업과 타 산업과 비교실증분석(comparative empirical analysis)함으로써, 정보통신산업에서 기술진보의 특성을 파악하였다. 본 연구의 실증분석 결과는 다음과 같다. (i) 기술확산측면에서 볼 때, 1990년 이후 IT 관련 기술진화는 타 산업의 기술진화속도에 비하여 매우 빠름을 알 수 있었다. (ii) 반면 정보통신 관련 techno cycle은 타 산업에 비하여 cycle 고저가(amplitudes) 매우 크게 나타났다. (iii) 우리나라 기술간에 techno clustering 특성은 산업간에 매우 유사한 특성을 지니고 있는 것으로 나타났다. 따라서 실증분석결과를 간단하게 요약하면, 정보통신산업은 최소한 2020년까지는 지속적으로 진화할 것이나, 그 기간동안에 다른 산업에 비하여 기술진화변동에 대한 폭이 클 것으로 분석되었다. 정보통신산업에 대한 기술 정책적 시사점은 장기적 안목에서 기술예측 및 조정이라는 안정적인 정보통신기술의 관리(techno management skills)가 중요한 요인으로 작용할 것이다.

This paper is focused on the investigation of the negative factors from smart-phone as internal affecting the use of smartphone and found their relationship. For the validation of this study model, 300 university students randomly selected in Seoul and Gyeongnam province. The measurement model was evaluated by using SPSS 18.0, and the evaluated result was summarized as follows. First, it was found that the techno-stress of smartphone user significantly associated with the fun and pleasure felt from using smatphone. It was assumed that a higher techno-stress negatively affects fun and pleasure from using smartphone. Second, the techno-stress of smartphone users was found to affect smartphone addiction. This means that more techno-stress users feel as they use smartphone, the more tendency to smartphone addiction. Third, flow was significantly associated with the smartphone addiction. Forth, Flow was significantly associated with satisfaction of the smartphones use. Fifth, it was indicated that when users had more flow and addiction from using smartphone, their satisfaction level was also higher.

The purpose of this study was to examine the relationship between techno-stress perceived by elementary school teachers and related variables in a flipped learning environment. To achieve the purpose, the following research question have been established: First, what is the difference between techno-stress perceived by elementary school teachers? Second, what is the difference between techno-stress related variables perceived by elementary school teachers? Third, how do the TPACK, teacher effectiveness, and school environment support, perceived by elementary school teachers, affect technostress? 207 teachers at elementary school responded on a questionnaire to measure their perceived techno-stress, TPACK, teacher efficacy, and school environment support. Data were analyzed with using independent two-sample t-test, one-way ANOVA, and multiple regression analysis. The results were as follows: First, the elementary school teachers working on a leading school perceived higher techno-overload and techno-complexity more than those in ordinary school. Second, the elementary school teachers showed differences in the perception of TPACK, teacher efficacy, and school environment support according to the teacher's career, and leading school. Third, the elementary schools teachers perceived in TK, TCK, TPACK, educational support, and technology have a positive affect with techno-stress. The results are significant in that they provided data for reducing techno-stress of elementary school teachers in a flipped learning environment.

The techno-park built-up project of Korea had begun in order to support regional enterprises since 1997. The number of techno-parks increased from 6 in 1997 to 17 in 2009 with various enterprise supporting services such as a new enterprise breeding, pilot production, and education and training. By way of renewing regional innovation promoting system, revising technopark law, and starting second step techno-park project, techno-parks have become centers for regional technology innovation, and cultivation of regional technology-based companies. Alternative policies for the development of techno-park projects are as follows: revitalizing the network among enterprises, universities, research institutes, and government; strengthening the ability to draw up projects in nurturing regional industry; and the establishment of fixed channels to support SME in the region.

There have been technologically distorted naturalization and overzealous digital culture in the formation and development of digital society in Korea. While the suppressive aspects of the 'neo-'authoritarian control and regulation have been excessively centered on the Internet, the autonomous actions of online users from below, with regards to their roles in agenda-setting function, have been evolved as the political. This paper aims to investigate the specificities in the developmental mode of digital technology in Korean society since the mid-90s. In this paper, 'techno-surplus' depicts the state that the abnormal is embedded within a technological artifact beyond its receptive ability. 'Techno-surplus society' designates such an extreme case of specifying technological surplus. In fact, the term of 'techno-surplus society' can be used for a metaphor symbolizing our society, in which social distortion and abnormality caused by 'techno-surplus' have been quite frequently happening, in its comparison to a degree of normality in the institutional politics. This paper explores the local specificities of 'techno-surplus society', in which the regressive aspects have stand out as being more different from the technological developments in China, Japan and the U.S.
