As network technologies evolve and so-called smart technologies appear, applications of smartphones are being applied in widespread areas. In general, the adoption of smartphones is different from the adoption of information systems. Thus, we tried to find out factors which may affect the user acceptance behavior. However, there have been some academic studies that analyzed the factors that affect user acceptance of smartphones, and their relationships. Under this academic background, we develop a model to examine how smartphones are accepted by users based on technology acceptance model. The theoretical model is validated through an online survey of smartphone users from two universities in Seoul, Korea. The results reveal that the users will have positive attitude towards adopting the smartphone when they perceive that the usage of smartphones is useful. We also find that the perceived usefulness of the smartphone is affected by the perceived ease of use and the media richness. The results also suggest that the perceived ease of use is determined by the self-efficacy whereas the intention to use smartphones is determined bv the perceived usefulness, the self-efficacy, and the attitude toward smartphnes' usage. Theoretical and practical implications are discussed.

음식물류 폐기물이 야기하는 환경오염 문제는 오랫동안 사회적인 문제였으나 2013년 런던협약 가입으로 인해 음·폐수 해양배출이 금지되면서 한층 심각해졌다. 최근 정부의 음식물류 폐기물 관련 종합 대책의 실시는 감량 성과와 자원화에 많은 기여를 하였으나 지속적으로 시행되지 못하였고 폐기물의 발생 분야별로 적절하게 대응하는 전략의 부족이 지적되었다. 많은 연구에서는 효과적인 감량 정책 시행을 위해서 무엇보다 시민의 참여가 중요하다고 강조하고 있다. 이 연구는 사용자 경험 분석을 기초로 음식물류 폐기물 처리기를 디자인하여 시민의 참여를 높이는 방안을 제안한다. 이를 위해 선행연구에 대한 다각적인 조사·분석, 표적 집단 인터뷰 및 사용자 여정지도를 포함한 사용자 경험연구를 통하여 디자인 개발 방향을 설정하였다. 연구 결과로 도출된 처리기는 폐기물의 수시 배출이 용이해지며 가정 내에서 음식물류 폐기물 배출 과정이 간단해진다. 또한 사용자와 폐기물이 직접적으로 접촉하는 순간은 처리기에 배출하는 시점으로 제한하여 사용자가 겪었던 부정적인 경험을 최소화함으로써 폐기물 감량을 위한 사용자의 적극적인 참여를 유도하였다.

The expansion of the world wide web has led to a huge amount of user generated content over different forums and social media platforms, these rich data resources offer the opportunity to reflect, and track changing public sentiments and help to develop proactive reactions strategies for decision and policy makers. Analysis of public emotions and opinions towards events and sentimental trends can help to address unforeseen areas of public concerns. The need of developing systems to analyze these sentiments and the topics behind them has emerged tremendously. While most existing works reported in the literature have been carried out in English, this paper, in contrast, aims to review recent research works in Arabic language in the field of thematic sentiment analysis and which techniques they have utilized to accomplish this task. The findings show that the prevailing techniques in Arabic topic-based sentiment analysis are based on traditional approaches and machine learning methods. In addition, it has been found that considerably limited recent studies have utilized deep learning approaches to build high performance models.

This study classified and analyzed the types of images posted on official accounts operated by domestic and foreign SPA brands on Instagram and Pinterest, which are image-based fashion curations, and performed a survey on preferred image types in the fashion curations of SPA brands. It aims to induce active apparel purchasing behavior of consumers through the suggestion of image types about fashion curations for effective communication between fashion brands and consumers. The survey to targets the 20s and 30s was carried out from October 23, 2015 until November 22 and conducted factor analysis, paired t-test. The above images were classified into four types based on previous studies: product images, brand images, lifestyle images, multiple images. The results of the survey were also divided into four factors in line with the classification of image types. Generally, foreign SPA brands(H&M, Uniqlo, Zara) used image-based fashion curation services more frequently than domestic SPA brands(8Seconds, Mixxo, Spao, Tngt). The analysis of image types in the fashion curations of SPA brands showed that product images accounted for the highest proportion of images used in the official accounts of SPA brands. However, the comparison of averages on the preferred image types of survey respondents showed that the users who had once visited the official accounts of SPA brands on Instagram and Pinterest preferred in the order of lifestyle information > product information > brand information > multiple information provided by SPA brands, which was statistically significant.

As National Education Information Systems (NEIS) is supposed to broadly introduced all over the country, we need to understand factors that would affect its successful use. Studies regarding the NEIS have been made in terms of a social issue according to its introduction and use, however there has been only little research made in terms of the use of the system so far. Therefore, this study aims to investigate the factors that would have effect on a successful use of the NEIS. A research model of the study is based on the extended DeLone and McLean's information systems success model with two characteristics of computer self-efficacy and perceived fairness. Based on the survey data from 168 subjects, the present study performs SEM analysis with PLS. The results show that perceived usefulness and computer self-efficacy improves the user satisfaction. However, the user' satisfaction does not cause system characteristics- system quality, information quality, service quality -and perceived fairness not effect. The study provides characteristics which can effectively and smoothly introduce the NEIS for its successful use on the upcoming full scale execution on the NEIS.
