  • 교통망의 확충계획이 있거나 확충작업이 이루어지고 있는 지역에서는 그로 인한 직접적인 접근성 증가와 더불어 교통망의 개선에 따른 접근성 증가의 주변지역으로의 파급효과를 정확히 신출할 수 있다면 지역 전체의 접근성 공간구조를 파악할 수 있게 되고, 지가와 토지이용의 변화를 정확히 예측할 수 있게 되어 교통을 포함한 각종 지역계획과정에서 효율적이고 합리적인 대안선정을 위한 기준을 제공할 수 있을 것이다. 기존의 그래프이론에 기반을 둔 접근성 측정모형에 의해 산출되는 결정점의 접근성 증가가 주변지역으로 파급되는 효과를 정확히 산출할 수 있는 이론적 모형의 개발을 시도하였다. 특히 결정점을 중심으로 주변지역으로 거리가 멀어지면서 변화하는 지하철 접근도의 영향력을 측정하기 위한 이론적 모형을 제시하고 있다. 지하철역의 접근도가 주변지역으로 확산되는 정도는 주변지역에서 그 지하철역을 이용하는 정도와 일치한다고 보고 주변지역의 지하철역 이용밀도를 기반으로 수학적 함수식을 도출하였다. 이러한 연구는 궁극적으로는 최근 지리적 분석기법으로 각광을 받고 있는 GIS기법에 접목시켜 지표현상의 설명에 핵심이 되는 접근성의 공간적 보간에 대한 이론적 근거를 마련한다는 의미를 지닌다.

  • 본 연구는 인터넷 개인방송의 이용동기와 수용자특성(초기수용자, 후기수용자)에 따른 만족도의 차이를 분석하였다. 이를 위해 아프리카TV(AfreecaTV)를 이용하는 10~30대 283명을 대상으로 설문을 실시하였으며, 다음과 같은 결과를 도출하였다. 분석결과 사용자의 하루 평균 사용시간은 이용 동기에 긍정적인 영향을 미쳤으며, 수용자특성에 따른 인구통계학적 특성차이에서는 학력에서만 차이가 있는 것으로 나타났다. 또한 만족도는 초기수용자의 경우 여가습관, 커뮤니케이션, 오락성, 접근성이 후기수용자는 접근성, 신뢰성, 여가습관, 최신성이 유의미한 요인으로 나타났다.

  • Although the diffusion of mobile services appears to be occurring much more rapidly than the spread of wired services, there are risks of a new type of digital divide: the mobile divide. The mobile divide, which refers to a specific digital divide that involves the unbalanced diffusion of mobile technologies, must be concretely studied. Thus, this study focuses on the mobile divide with respect to disadvantaged populations. Although various studies suggest that the diffusion of mobile devices may reduce the digital divide, somestudies argue against the positive effect of mobile devices in addressing traditional digital devices. Low and O'Connell (2006) insisted that equity of access to mobile technologies should be considered in the contextof the traditional digital divide; they argued that there may be socio-economic barriers to accessing mobile devices and the mobile Internet that are similar to the socio-economic barriers to accessing stationary computers and the stationary use of the Internet. Focusing on the smartphone divide, this study suggests that emphasizing utilization is an appropriate manner in which to bridge the mobile divide rather than focusing on other factors, such as accessibility and capability, thatprevious studies have used to measure the traditional digital divide.

소셜 미디어는 캐즘(Chasm)과 구매 가치에 얼마나 영향을 미치는가? : 채택 집단간 정보력 및 신뢰도 효과 (How Much Impact do Social Media Make on Chasm and Buyer's Value? : The Information Accessibility and Trust Effect among Adopting Groups)

  • This paper is to investigate the degree of impact of social media use on buyer's value. Buyers of innovative digital devise are classified into three groups based on adopting behaviors. This study focuses on the degree of changes in information accessability and trust, and their associations with increased value perceived in resulting quality life. The result shows the gap in information accessability has disappeared while the one in trust remained. This implies that the gap among adopters in diffusion curve, so-called the chasm notion is very likely to be lessened or disappeared due to social network openness. Also, shown are the relationship of these variables with the degree of purchase value more stable with information accessability than with trust, all in varying patterns though. It implies that information sharing through social media be accompanied with source credibility in order to be of more value not only to buyers but also to sellers especially for new interactive devices.

  • Purpose - Over recent years, we have concerned about safety and quality on food products because of delivery complexity. The dependence of foreign food products escalate supply of products. And there are often negligent accident of marine and agricultural products. Therefore, the complexity increases the importance of safety on food and information quality for consumers. In spite of the interest augmentation of various interested parties, there is decrease in reliability and effectiveness, if it would be established without the right directivity. For the study, we tried to examine the first considerations the point of - view in service environment and information quality with accepting and diffusing the Traceability System. Then, we tried to verify the relationships between the factors of TS and the determinants of behavior decision. Next, we made efforts to find the mutual relationship among distributors, producers, consumers and the other prerequisite factors from the point of view in service environment and information quality in order to operate effectively the information perspective and system. Research design, data, and methodology - For the purpose of this study, the samples of consumers were targeted to Traceability System, and 661 people have been investigated. Through theoretical discussion of previous research, nine hypotheses were established, the influence of Continuous User Intention in TS. In order to test the hypotheses, a survey had conducted for 661 consumers as opinion leaders in their 20s-60s as data, and structural equation modeling was used. The difference analysis between Agricultural and Marine Products in TS; SPSS 22.0 and AMOS 22.0 were used for statistical analysis. Results - The major findings from this study were as follow; all factors of information quality excluding completeness and a social-impact had effects on the ease of use; all factors excluding understand ability in information quality and a social-impact had effects on the usefulness; completeness and social-impact had effects on perceived value; the ease of use had effects on usefulness and perceived value; usefulness had effects on perceived value and the intention of continuous use. From the results of different analysis, the CPLT(Completeness) factor has positive effects on Easy of USE and PV(Perceived Value) strongly in agricultural products. On the other hand, Social Duty has positive effects on Easy of Use strongly in marine products. Conclusion - In the age of information overflowing, TS will be a burden for users if it places too much emphasis upon accessibility. To accept and diffuse TS safely, therefore, Information System should be settled first into initial market formation. In addition, if TS elements are considered in conjunction with information factors and user environment, the acceptance and diffusion of TS would make synergy effect, even better. That is, this study contributes to the acceptance and diffusion of Traceability System. Accordingly, information quality will be settled into initial market formation. Also, social-impact element will be considered in conjunction with information quality's factors, and it will make synergy effect.
