This study investigates the credibility judgements of information by tweens using digital media and information. Particularly, the study focused on tweens' perception of internet research and information use and on their credibility judgement of source and message, internet service providers, and on consulting with others for their credibility judgement. The survey methodology was used to collect data from grade 5 and 6 students in two elementary schools whose parents are likely in middle and upper class. 336 valid questionnaires were collected among 400. Descriptive statistics, factor analysis, and t-test were used to analyze the data collected using SPSS 25. Findings suggested that tweens understood the importance of using smart media and computers, that they used Youtube, Naver, Kakao talk, Naver JisikIN much in sequence, and that they believed the Internet research was easy and fun. Using exploratory factor analysis, the survey questions for credibility judgement were classified into three factors: Internet service providers, sources and information, and consulting with others. Tweens used sources and information credibility, consulting with others credibility, Internet service providers credibility in sequence. However, it was interesting to find that there were greater deviation in answers on knowing how to find out the cognitive authority of the authors and on the importance of using current information. This study suggests the critical need for tweens' credibility judgement research for promoting critical thinking skills as well as for proactive educational practices in schools and libraries on information literacy.

인터넷의 안전한 사용과 전자상거래의 안전·신뢰성 확보에 필요한 핵심 정보보호 기술에 대한 표준화 요구가 급증하면서 정보보호에 관한 표준화 작업이 활발히 진행되고 있다 이러한 측면의 국제적인 노력으로는 ISO/IEC JTC 1SC27 ITU-T, IETF의 정보보호 표준화 작업을 들수 있다 특히 IETF는 인터넷의 통일성과 표준을 유지하기 위해 설립된 조직으로 인터넷 표준의 개발 민 선정을 목적으로 정부기관 업계, 학계 등 다양한 분야의 연구개발자들로 구성된 개방된 형태의 국제 단체이다 IETF는 인터넷과 관련하여 다양한 분야의 기술표준화를 수행하고 있으며 정보보호 기술 표준화에 대해서도 활발한 활동을 수행하고 있다 본고에서는 IETF의 조직과 표준화 절차를 소개하고 정보보호 분야의 표준화 활동을 소개한다.

This paper tried to analyse the factors influencing consumer trust and the relationships between cause variables and results in Internet Shopping Mall. In order to do so, this paper tried to analyse the trust factors in TV Home Shopping as well as Internet Shopping Mall in terms of cyber markets both. There found six factors ： perceived factor before purchasing, perceived factor after purchasing, perceived and emotional factors in the course of purchasing, positive and negative emotional factors after purchasing. These factors are correlated with Internet shopping variables and we can measure how Internet shopping variables can affect trust to the shopping mall. We can compare the trust factors of TV home shopping with those of Internet shopping mall and then we can activate Internet Shopping Mall. More implications of this study and further researches should be discussed in the future research.

A multihomed enterprise or AS(Autonomous System) improves reliability and performance by acquiring its Internet connectivity from more than two ISP(Internet Service Provider). Multihoming protocol must allow a multihomed site whose connectivity through one of the ISPs fails to keep its Internet connectivity As one of mechanisms to do this, tunneling mechanism through Non-direct EBGP(Exterior Border Gateway Protocol) is defined. This mechanism makes connectivity to the Internet more reliable, but causes the problem that makes the communication route non-optimal. In this paper, we propose the route optimization mechanism using an extension header in the IPv6 multihoming environment.

본 논문에서는 인터넷 가전제어를 위한 전력선 통신망 채널 특성 추정 기법을 제시하였고 실 거주 댁내 전력선 통신망의 채널 특성을 실측하여 통신 신뢰도를 평가하였다. 전력선 통신 기능을 내장한 동일 모델의 네트워크 가전제품 4종(에어컨, 냉장고, 세탁기, 전자렌지)을 실 거주 가정 100가구에 설치하여 전력선 통신망의 통신 신뢰도를 평가하였다. 통신 신뢰도의 평가 결과 통신 신뢰도가 90%이상이 나타나는 것을 확인하였다. 이것은 PLC모뎀이 장착된 가전제품의 활용과 고밀도 아파트 주거 지역에서 인터넷 가전제어를 위한 서비스가 상업적으로 이용할 수 있는 근거를 뒷받침한다고 할 수 있다.

본 연구는 카탈로그와 케이블 TV, 인터넷 홈쇼핑 정보전달 매체별로 의류제품에 대한 소비자의 인식 및 기대 수준을 비교 분석하여 홈쇼핑의 정보전달 매체 개발에 기초적인 자료를 구축하기 위하여 설문조사를 실시하였다. 설문조사 대상자는 20세 이상의 카탈로그 홈쇼핑사 회원 219명, 케이블 TV 홈쇼핑사 회원 213명, 네티즌 972명이었다. 매체별 이용자의 분포는 카탈로그와 케이블 TV 홈쇼핑의 경우 여성과 기혼자가 많았고 직업은 주부와 사무직이 많았다. 반면 인터넷 이용자는 남성과 미혼자가 많았고 직업은 사무직이 많았다. 학력은 세 매체 모두 응답자의 절반 이상이 대졸 이상으로 교육수준이 높았다. 설문조사 결과 의류 홈쇼핑에 대한 매체별 소비자의 인식은 다음과 같았다. 1. 케이블 TV 홈쇼핑 이용자들은 케이블 TV를 통해 판매되는 의류제품이 디자인, 색상이 다양하며, 제품의 소재나 품질, 치수에 대한 정보도 충분하다고 느끼며 의류의 품질 신뢰도와 구매의사도 높은 것으로 나타났다. 2. 통신판매를 이용해서 의류를 구매해 본 경험이 있는 집단은 구매를 경험하지 못한 집단보다 구매의사도 높으며 통신판매에 대한 신뢰성도 높은 것으로 나타났다. 특히 케이블 TV 홈쇼핑을 통해 의류제품을 구매해 본 경험이 있는 집단이 의류제품 정보의 다양성에 대한 만족감과 품질 신뢰성이 가장 높았다. 3. 매체와 성별의 차이를 살펴본 결과 케이블 TV를 이용하는 여성은 의류제품의 다양성, 충분한 제품정보, 품질의 신뢰성, 구매의사에 가장 긍정적인 인식을 가지고 있는 것으로 나타났다. 4. 케이블 TV를 이용하는 기혼자와 고소득자가 다른 집단보다 의류제품의 다양성, 제품정보와 품질 신뢰성, 구매의사에서 가장 긍정적인 인식을 가진 집단이었다. 본 연구의 결과는 케이블 TV 홈쇼핑은 카탈로그와 인터넷에 비해 소비자의 욕구를 충족시키는 제품과 소개방식으로 의류를 판매하고 있으며, 특히 의류제품 구매 경험이 있고 고소득층이며 기혼인 여성들을 만족시킬만한 다양한 상품을 구비하고 자세한 제품정보를 제공하며 품질에 대한 신뢰를 심어 주어 긍정적인 구매의사를 갖도록 유도하고 있는 것으로 해석된다.

As the internet is widely distributed. the intelligent search agent is commonly used to meet the needs of user. But these Intelligent multi-agents are so independent each other that they can not give reliability of information and also have difficulty in coping with the dynamic distributed environments due to the short of cooperation abilities among multiagent. To resolve these problems. this paper proposes the mechanism for efficient cooperation and information processing by creating agency within broker agent and clustering multi agent's agency using neural network. For reliability of information. we also propose the multiagent management mechanism that can improve the information update problems which are in existing search systems and evaluate the performance of this research through simulation.

With rapid growth and competition of electronic commerce through internet, various buying types and business models are being appeared In this paper, we studied group buying which is new business model to consumer and factors affecting on trust and participation of group buying. The following are the regression result of this study. First, factors affecting on trust of group buying were different from factors affecting on participation of group buying. Second, perceived reputation factor, familiarity factor and product value factor made a significant effect on participation of group buying. Third customer service factor didn't make a significant effect on both participation and trust of group buying. Fourth, product value factor made a significant effect on both participation and trust of group buying. Fifth trust of group buying made a significant effect on participation of group buying
