Traditional Internet pricing schemes are coming under continual pressure to adapt to, and encourage, a changing mix of Internet applications and consumer usage patterns. Much research effort over the last decade has been focused on developing more efficient and attractive charging schemes. However, none of the proposed models has been widely deployed. This raises questions regarding the inhibiting factors and missing pieces that make pricing the Internet such a challenge. In this paper, we discuss the problems with current Internet pricing schemes, review the history of Internet pricing research over the last ten years, and summarize the key features and motivations of the most significant models. We develop a novel visual approach to comparing and evaluating such schemes using a three-dimensional (3D) metric encompassing technical efficiency, economic efficiency, and social impact. We address and discuss the important factors that have inhibited the deployment of the reviewed models and suggest productive areas of focus for future Internet pricing research.

Recently, Internet Telephony has become increasingly popular in telecommunication industry. However, previous research on Internet Telephony has focused on analyzing specific Internet Telephonysolutions, identifyingthe Internet Telephony movement itself. The research on prediction models about Internet Telephony adoption has been minimal. The main propose of this study is to develop models for predicting transition intention from using traditional telephones to using Internet Telephony. To do so, this study uses data mining methods to analyze demands in the IT communications market and to provide management strategies for Internet telephony providers. Especially this study uses discriminant analysis, logistic regression, classification tree, and neural nets to develop those prediction models toward Internet Telephony adoption. The models are compared with each other and a superior model is chosen.

본 연구는 미국의 토론 모형인 CEDA (Cross Examination Debate Association)방식을 인터넷 토론학습에 적용하는 새로운 시도를 통하여 향후 인터넷 수업에 응용할 수 있는 CEDA형 인터넷 토론수업 모델을 설계하는데 그 목적이 있다. 먼저 본 연구는 미국의 CEDA토론 기법의 기본 요소를 인터넷 토론학습모델에 적용한 수업설계를 통하여 1,2차에 걸쳐 각각 200명의 학습자들에게 인터넷 CEDA토론을 실시하고 그 결과와 토론에 대한 의견을 분석하였다. 연구결과 학생들은 인터넷 CEDA토론학습에 대해 긍정적인 반응을 나타냈으며, 기존의 개방형 토론방법보다 찬반형의 CEDA토론방법을 선호하는 것으로 밝혀졌다. 하지만 2차 연구에서는 토론에서 튜터의 중요성이 강조되며 튜터의 전략에 따라 토론결과가 달라 질 수 있음을 보여주었다. 이는 대부분의 학습자들이 스스로 토론에 대한 경험이 부족함을 보완하기 위해 튜터의 지원을 원하는 것으로 판단된다. 결론으로 본 연구는 CEDA형 인터넷 토론학습 모델이 학교현장에 폭넓게 활용될 수 있도록 교과목별, 학습자별 다양한 토론학습 모델이 개발되어야 하며 학습자 입장에서 토론수업을 지원할 수 있는 전략이 필요함을 강조한다.

최근 우리 사회는 인터넷과 네트워크의 발전에 따라 자유롭게 정보를 공유하거나 습득하게 되었다. 그러나 인터넷의 발전으로 인해서 그에 대한 역기능도 나타나게 되었다. 대표적인 역기능이 바로 인터넷 공격이다. 인터넷 공격은 여러 분야에서 많은 피해를 주는데, 특히 경제적인 측면에서의 그 피해는 어마어마하다. 특히 기업의 경우는 이런 경제적인 피해에 민감하다. 그러나 국내에서는 이런 인터넷 공격으로 인한 경제적인 피해를 산정하는 모델에 관한 연구가 미비하다. 따라서 본 논문에서는 인터넷 공격으로 인한 경제적인 측면의 피해를 산출하는 하나의 모델을 제시하고 그 모델의 기준에 따라 가상적인 인터넷 공격의 경제적인 피해를 산정할 것이다.

The purposes of this study was to investigate discriminative factors of clothing buying intention on Internet shopping mall. The sample included 435 male(44.8%) and female(55.2% ) adults, and an instrument was developed based on previous studies. The statistical analysis used for this study were factor analysis, 1-test, and LISREL. The results of factor analysis showed that consumers evaluated apparel internet shopping attributes based on perceptional dimensions of internet shopping consisted of clothing quality and value. web service quality and value, and adoption of internet shopping. Each dimension has sub-factors as follows: (1) clothing quality was perceived as 'artistry' 'sociality' and 'practicality'. (2) web interface service quality was perceived as 'visuality', 'advantage', 'response', 'dependability' and 'buying-confidence'. (3) internet shopping adoption was perceived as 'usefulness' and 'convenience'. T-test revealed that consumer's buying intention, re-entry intention, and store attitude were differed concerning all sub-factors including 'usefulness' and 'convenience' in adoption of Internet shopping dimension. As a result of LISREL, clothing buying intention path model was set up as following path. (1) 'artistry', 'sociality' and 'practicality' of clothing quality affected clothing value perception positively. (2) 'visuality', 'advantage', 'response' and 'buying-confidence' of web service quality affected web service value perception positively. (3) clothing and web service value perception affected store attitude positively. (4) store attitude affected clothing buying intention positively. However, Adoption of Internet shopping dimension that was perceived as usefulness and convenience did not affect clothing buying intention path model. Therefore, consumers buying, intention model in internet circumstance could be used nearly the same as real market circumstance.

Objectives : To develop measurement scales of Internet addiction, and propose a Korean Internet Addiction Index (K-IAI) and classification criteria for Internet addiction from the threshold scores developed. Methods : The identification of the concept of 'Internet addiction' was based on the literature review. To select the scales, an exploratory factor analysis was applied. A construct validation was tested by a confirmatory factor analysis (CFA) with a structured equation model (SEM). In testing the validity of the classification criteria, ANOVA and non-recursive models with SEM were applied. Results : Out of 1,080 questionnaires distributed, 1,037 were returned,; a response rate of 96%. The Cronbach-$\alpha$ of all items was over 0.75. Using an exploratory factor analysis in the condition of a 6 factor constrain as the study model proposed, 23 of the initial 28 items were identified. In testing the discriminant and convergent validity of the selected 23 scales using CFA with SEM, the Internet addiction model explained about 93% of all variances of the data collected, and all the latent variables significantly explained the designated scales. A K-IAI was proposed using the T-scores of the sum of all factor averages. In the classification of users, the basic concept was a twostandard deviation approach of the K-IAI as the criteria of MMPI. The addiction group had a score ${\geq}70$ in the K-IAI, the pre-addiction group between ${\geq}50$ and <70, and the average user group <50. The Internet use times of the classified groups were statistically different in the ANOVA and multiple comparisons. Conclusions : The K-IAI is a reliable and valid instrument for measuring Internet addiction. Moreover, the taxonomy of the groups was also verified using various methods.

본 연구는 인터넷 사용, 가족 관계, 사이버폭력 피해 간의 관계를 모형 비교를 통해 검증한 것이다. 변인 간의 관계를 검증하기 위해 한국정보화진흥원의 2013년 인터넷중독 실태조사를 활용하였다. 구조방정식 분석을 통해 인터넷 사용이 가족관계를 완전 매개하여 사이버폭력 피해에 영향을 미치는 모형(모델 1)과 인터넷 사용이 가족관계를 부분 매개하여 사이버폭력에 영향을 미치는 모형(모델 2)을 비교하였다. 최종모형(모델 1)에 의하면, 인터넷 사용이 증가할수록 가족 간의 유대는 더 낮아지는 것으로 나타났고, 가족 간의 유대가 낮을수록 사이버폭력 피해는 더 커지는 것으로 나타났다. 본 연구는 인터넷 사용이 사이버폭력 피해에 직접적인 영향을 미치기 보다는 가족 관계가 두 변인간의 관계가 성립되는데 중요한 역할을 한다는 것을 밝혀낸 것에 의미가 있다. 본 연구결과를 참조하여 정책적 시사점을 제안했다.

The purpose of this paper is to investigate the diffusion process of mobile internet use in Korea and to explore the determinants driving MIU. A survey was conducted to collect data to empirically assess the research model. In total, 543 usable responses were collected using a questionnaire derived from previous research. Both the structural equation model and partial least squares were used to study the model concerning different user groups. Findings, The results indicate that there are significant differences in the users' perceptions of mobile internet usage during its different innovation diffusion stages. Of the determinants, perceived enjoyment is the most important predictor of mobile internet use. In addition to motivating users by making services more enjoyable, the findings suggest that practitioners should take the differences of adopter groups into account. Making the mobile internet easy to use and compatible with users' lifestyles would promote the use of technology as well.
