There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.

By far, numerous e-government projects requiring huge investments have been conducted in Korea to increase the administrative efficiency and improve the service quality via Internet. However, there's little research focusing on methods and techniques for analyzing and evaluating the projects either to economically justify the investments or to assess the quality of the system and of on-line services to citizens. The purpose of this paper is to suggest a set of factors to take into account for evaluating e-government portals and to empirically test the factors to provide useful implications for building such portals. Based on the literature reviewed, we constructed a research model that includes content, public service, community, design, technology, and portal's attributes as independent variables and the user's satisfaction and the administrative efficiency as dependent variables. A reliability test revealed that the evaluation factors proposed in the paper are sufficiently reliable, and a multi-regression analysis indicated that five hypotheses should be accepted. The findings of the study suggest that emphasis should be placed on public service quality and portal site attributes, among others, when implementing portals.

This study identified consumer perceptions of biotechnology crops, provided the types and sources of information on agricultural biotech that consumers demand, and derived effective methods of providing agricultural biotech information by analyzing problems and improving the information available online regarding agricultural biotech. The analysis of sources of information on agricultural biotech showed that there were differences between preference and reliability. Respondents preferred the Internet (47.6%) and TV (36.3%), while they relied on TV (36.3%) the most, followed by the Internet (26.6%), and academic papers and technical books (23.1%). Only 27.1% of the respondents answered that they collect information on agricultural biotech proactively. The higher frequency of information collection indicated a higher satisfaction rate with the information that was being collected. Survey results for the websites that respondents preferred and relied on to collect information were that the most preferred websites were web portals (53.4%), while reliability rates across the various types of websites were relatively even: web portals (28.4%), academic institution websites (19.1%), and websites that provide professional information (18.2%). Surveys that examined factors that were important in choosing the websites for collecting information on biotech indicated that factors such as "Providing verified data and citation" and "Providing objectivity" were the most important. Examining the preferences and factors of preference by content type showed that the demand for visual aids, such as photos, tables, graphs, and videos, was high, and there were statistically significant differences between the factors of preference by content type.

Personalization and customization of product and service designs involving firms and customers using online design interfaces across the Internet is increasingly being facilitated by brands. Research on the role of information technology and value co-creation across various research disciplines in management has provided learnings on ways to creatively improve products and services by integrating customers and firms in web portals. This paper provides a comprehensive analysis of the specific attributes of value co-creation between customers and firms relevant to business logic, learnings, projects, personalized products and services, social network innovations, brand management and markets across the Internet for the purpose of enhancing information management of value co-creation for industries and research. The paper draws on published research and industry surveys on how value co-creation is growing in the digital economy. An industry survey of managers who use web portals for their business responded to a questionnaire on how various social, economic and intellectual motivation factors of firm-customer interactions result in value co-creation for customers and firms. These motivation factors can lead to improved learning systems for business process improvements and service management for industries, customers and firms and may also be classified.

연구의 목적은 3개 모바일 포털사이트의 응답시간을 분포를 이용하여 비교하고 분류하는 것이다. 연구대상은 Naver, Daum, Nate의 모바일 포털 사이트 접속페이지이며, 실험기간은 모바일 포털들이 활성화되기 시작되던 즈음인 2012년 4월 18일에서 2018년 4월 17일까지 6년간이다. 그리고 실험횟수는 4,060회이다. 분포비교를 위해 히스토그램과 백분율을 이용하였으며 이론적인 비교를 위해 모수적 방법인 카이스케어 검정과 비모수적 방법인 콜모고로프-스미르노프 검정을 실시하였다. 네가지 방법 모두 Naver가 가장 빨랐고, 다음이 Nate, Daum이 가장 느렸다. 평균 응답시간 면에서도 같은 결과를 낳았다. 이러한 결과는 유선 포털의 결과와 정반대로서, Naver는 매체 특성에 맞게 유선에서는 많은 콘텐츠를 무선에서는 응답시간을 높이는 전략이고, Daum은 무선에서 응답시간을 희생하면서 콘텐츠를 중시하는 전략을 구사하고 있음을 알 수 있다. 분류에서는 응답시간에 따라 "Comfortable"과 "Tolerable", "Feedback", "Leave"로 나누었으며, 이용자들이 떠날 수 있다는 7초 이상인 "Leave"의 비율이 Naver는 1.18%, Daum이 11.70%, Nate가 1.5%로 Daum이 압도적으로 높아서 Daum의 응답시간은 개선이 매우 절실한 수준임을 알 수 있다. 또한 분류 결과에 의하면 3개 모바일 포털들이 응답시간을 줄이는 것이 필요하다는 것을 밝혔다. 본 논문의 결과가 모바일 포털들의 응답시간을 줄이는 기술경쟁을 촉진할 수 있기를 기대한다.

향후 무선인터넷 망이 완전히 개방되면 다양한 포털, 컨텐츠 사업자가 등장할 것이다. 이는 사용자에게는 다양한 서비스를 받을 수 있는 장점이 있지만 현재 휴대폰에서의 모바일 인터넷 컨텐츠 탐색 시 발생하는 사용성 문자를 한층 더 증대 시킬 것으로 예상된다. 기존의 연구들은 단일 포털 업체만을 대상으로 연구를 하였기 때문에 여러 포털 업체에서 제공하고 있는 컨텐츠들을 적절히 탐색할 수 있는 기법에 대해서는 아직 연구가 부족하다. 본 논문에서는 시멘틱 웹 구현 기법 중 하나인 토픽맵을 이용하여 효율적으로 모바일 인터넷 컨텐츠를 탐색하고 관리할 수 있는 기법을 제안한다.

최근에 인터넷 포털 기업들은 기존 고객을 유지하고 신규고객을 유치하기 위해 이메일 용량 증대를 앞다투어 발표하고 있다. 그러나 이러한 전략이 사이트 이동에 따른 고객 전환비용의 발생 때문에 성공적일지는 확실치 않다. 따라서 그들의 전략이 실효성이 있을지를 알아보기 위하여 본 연구는 용량 증대로 인한 이메일 서비스의 고객 전환의도에 영향을 미치는 직접적 요인들과 상황적 요인들을 검토한다. 연구 결과는 대안의 매력, 전환비용, 고객 만족 모두가 이메일 서비스의 고객 전환의도에 상당한 직접적 영향을 가지는 것으로 나타났다. 또한 대안의 매력은 고객 전환의도에 대한 조절효과가 있는 것으로 나타났으나 전환비용은 어떠한 조절 효과도 보이지 않았다. 결론적으로 인터넷 포탈 기업들의 공격적인 용량 증대 전략은 고객 베이스를 증대할 수 있는 효과를 거둘 가능성이 매우 높아 보인다.

News contents, produced for paper readers, are more and more being used online instead of offline. Internet sites, expecially portals(naver, daum, nate etc.) are dominant marketplaces, where news are exchanged and values are added. So, establishing a new online news service system, which can satisfy news provider(copyright owner) and internet service provider together, is a necessary task under current online-dominant news service environment. UCI(Universal & Ubiquitous Content Identifier) and IPTC NewsML(News Mark-up Language) are considered as useful standards to compromise protection of news-copyright and enhancement of online use of news contents. This study is based on a real case of 'NewsBank' in korea, We expect that this study can show an inspiration to obtain two contradictory goals of copyright protection and free online use of copyright.

An increasing number of companies in the fashion industry are using AI curation services. The purpose of this study is to investigate perceptions of and intentions to use AI fashion curation services among customers by using text mining. To accomplish this goal, we collected a total of 34,190 online posts from two Korean portals, Naver and Daum. We conducted frequency analysis to identify the most frequently mentioned keywords using Textom. The analysis extracted "various," "good," "many," "right," and "new" at the highest frequency, indicating that consumers had positive perceptions of AI fashion curation services. In addition, we conducted a semantic network analysis with the top-50 most frequently used keywords, classifying customers' perceptions of AI fashion curation services into three groups: shopping, platform, and business profit. We also identified the factors that boost continuous use intentions: usability, usefulness, reliability, enjoyment, and personalization. We conclude this paper by discussing the theoretical and practical implications of these findings.
