Smart speakers represent a growing product in home electronics. However, their capability to record voices in their immediate surroundings has spurred concerns about privacy violations. In this paper, we assess the extent of those concerns in the opinions of smart speaker users by examining the reviews posted by smart speaker users. We focus on South Korea as a representative of advanced Asian economies. The results show that Korean smart speaker users are either unconcerned or unaware of privacy issues, confirming the results of previous studies about UK users, but with an even lower degree of interest in the topic. However, for the few users concerned about privacy, their attitude towards privacy influences their overall opinion about smart speakers.

이전의 SNS 이용자의도에 대한 연구는 주로 재방문의도에 관심을 가졌으나, 본 연구는 재방문의도와 전환의도를 함께 고려한 연구결과를 도출해냈다. 연구결과에 따르면 (1) 사회적 상호작용과 SNS 중독은 선행요인에 다른 영향을 미치고 있고, (2) 즐거움과 유용성은 SNS 이용자의 재방문의도를 높여주고 있으며, (3) SNS 이용자는 현재 이용하고 있는 SNS에 대한 부정적인 인식을 가지고 있는 경우에도 전환을 고려하지 않고 있음을 확인하였다. 이 연구결과는 SNS 기업이 시장을 지배하기 위해서는 SNS 이용자가 사회적 상호작용을 보다 활발하게 할 수 있는 서비스 제공과 부정적인 인식을 가지고 있는 SNS 이용자를 적극적인 참여자로 유도하기 위한 전략이 필요하다는 점을 시사한다.

현재 대부분의 대학도서관에서는 Web 2.0을 기반으로 한 인터넷 검색엔진의 기능을 온라인목록에 적용시킨 OPAC 2.0 서비스를 제공하고 있다. 새로운 서비스 제공은 이용자들의 편의를 위해 필요한 것이며 그렇기 때문에 중요한 것은 각 서비스에 대한 이용자들의 의견을 고려하는 것이다. 이에 본 연구에서는 대학도서관 OPAC 2.0 이용자인 대학생들을 대상으로 OPAC 2.0 서비스(주요 기능)에 대한 중요도 인식과 이와 관련된 도서검색시 이용하게 되는 이용원 및 그 이유에 대하여 조사 및 분석하였다. 조사 및 분석결과 OPAC 2.0 서비스에 대하여 이용자들은 '정확하고 만족스러운 검색결과'를 원하고 있었으며 단순히 '화면이 익숙하고 열람 및 대출이 편리하다.'는 이유로 '소속 대학도서관 온라인목록'을 도서검색 정보원으로 이용하고 있었다. 이용자들의 의견이 고려된 OPAC 2.0 서비스의 개선이 필요하다.

Mobile Banking Applications (MBAPs) is one of the recent fads in mobile trading applications (Apps). MBAPs permit users to execute exchanges of money and many more whenever it might suit them; however, the primary issue for mobile banking Apps is usability. Hardly any investigation analyzes usability issues dependent on user's age, gender, exchanging accomplices, or experience. The purpose of this study is to determine the degree of usability issues, and experience of mobile banking users. The survey employs a quantitative method and performs user experiment on 240 participants with six different tasks on the application's interface. The post experiment survey is done with concerning participants. On the other hand, banking experts and Information Technology (IT) expert's group is also involved after the experiment. Expert's opinions about existing mobile banking Apps and suggestions for improving usability of MBAPs are collected through physical means (like questionnaire and interview) and online means like Google form. After that comparison of the opinions of users and experts about MBAPs is performed. The experimentation measures the tasks usability of various mobile banking apps with respect to its effectiveness, efficiency, trustfulness, learnability, memorability and satisfaction. The usability testing was led at different Universities and the outcomes acquired show that there are privacy and trust issues with their mobile banking apps. There is also a gap between users and experts which should be minimized by applying customized usability models, modes concept like other application software and also by adding complete features of banking in MBAPs. It will benefit mobile banking apps users, developers and usability engineers by providing user-friendly which are up to the mark of user's requirements.

Massive numbers of users of social networks share various types of information such as opinions, news, and ideas in real time. As a new form of social network, Twitter is a particularly useful information source. Studying influence can help us better understand the role of social networks. The popularity of social networks like Twitter is primarily measured by the number of followers. The number of followers in Twitter and the number of users exposed to news media are important factors in measuring influence. We chose Twitter and the New York Times as representative media to analyze the influence and present an empirical analysis of these datasets. When the correlation between the number of followers in Twitter and the number of users exposed to the New York Times is computed, the result is moderately high. The correlation between the number of users exposed to the New York Times and the number of sections including the users on it, was found to be very high. We measure the normalized influence score using our proposed expression based on the two correlation coefficients.

This study is to survey facilities installed at urban parks and identify park facilities desired by users through a questionnaire survey of users who actually use the parks. Then, the outcome will be compared and evaluated to install urban park facilities that reflect the desires of users in the future. Findings showed that park facilities currently installed are mostly those easy to install and manage among facilities suggested in relevant laws. Regardless of park types and sizes, similar facilities were installed across parks. A questionnaire survey of users showed that they wanted facilities to rest, sports facilities, waterscape facilities and facilities to accompany families. The result also showed that they wanted green area-style parks that have a lot of trees. Therefore, going forward, facilities reflecting such desires of users should be installed at parks as much as possible. When developing a park creation plan for each city, it would be critical to survey the opinions of residents in relevant areas in advance and reflect it to the creation plan.

Recently, many users frequently share their opinions on diverse issues using various social media. Therefore, many governments have attempted to establish or improve national policies according to the public opinions captured from the various social media. In this paper, we indicate several limitations of traditional approaches for analyzing public opinions about science and technology and provide an alternative methodology to overcome the limitations. First of all, we distinguish science and technology analysis phase and social issue analysis phase to reflect the fact that public opinion can be formed only when a certain science and technology is applied to a specific social issue. Next, we apply a start list and a stop list successively to acquire clarified and interesting results. Finally, to identify most appropriate documents fitting to a given subject, we develop a new concept of logical filter that consists of not only mere keywords but also a logical relationship among keywords. This study then analyzes the possibilities for the practical use of the proposed methodology thorough its application to discovering core issues and public opinions from 1,700,886 documents comprising SNS, blog, news, and discussion.

스마트폰과 태블릿PC 등의 스마트기기의 확산으로 모바일 기반 인터넷의 이용률이 눈에 띄게 증가하였으며, 이로 인해 모바일 인터넷의 영향력도 중요해졌다. 따라서 본 연구는 지난 일주일동안 모바일 인터넷을 통해 뉴스를 본 뉴스 이용자의 어떠한 특성들에 따라 정치, 경제, 사회적 주요 현안에 대한 의견을 형성할 때 모바일 인터넷의 영향을 받는지 파악하고자 수행되었다. 이를 위해 한국 언론 진흥재단의 2016년과 2017년의 언론수용자 의식조사의 자료를 분석에 사용하였다. 모바일 인터넷 뉴스 이용자의 성별, 연령, 학력, 가구소득, 뉴스 이용일수, 뉴스 이용시간, 언론사 애플리케이션 이용일수, 뉴스모음 애플리케이션 이용일수, 포털 이용일수, 언론사 공식 홈페이지 이용일수를 뉴스 이용자의 특성으로 지정하였다. 모바일 인터넷 의견 형성 여부에 뉴스 이용자의 어떠한 특성이 영향을 미치는지 알아보기 위해 다중 로지스틱 회귀를 적합하고 해석하였다.

Customized service is a vital and mandatory element for apps in improving their technical performance and app customer analysis. While apps require users' consent for their data extraction and usage, many of the terms and agreement forms are written intricately, making it harder for users to fully understand the whole concept of users' data collection for customized services. Ever since the Facebook-Cambridge Analytica scandal, personal data privacy has been re-examined, forcing many app companies to reinforce a reliable solution to data privacy issues. However, there has not been a secured solution, which worries many people about the future advanced issues when metaverse platforms are actively used in daily apps. The research aims to collect the reactions and behaviors of everyday app users who utilize apps with customized services to understand the nature of privacy data issues and the users' opinions about the future implementation of metaverse platforms. The method of the research was an online questionnaire that targeted university students. The study revealed many fearful and anxious reactions about personal data and further metaverse issues where most app users were uneducated about how current apps collect and utilize users' private data.
