Because of rapid advance of wireless Internet-related technology and fast diffusion of Smart phone, a variety of mobile applications through domestic and foreign app stores have been made and used. Under the recognition of current trend, both central government and local government have developed and provided public mobile app in order to accomplish the mobile e-government. However, public mobile app is not popular in spite of vast investment for its development and service. This study investigated current issues and problems of public mobile app in public service, management, and technology aspects. To do so, this study categorized the interested people of public mobile app into users, providers, and developers, and conducted deep interviews to them. Based on the interview results, the study suggested the following recommendations for the activating tools of public mobile app: providing user-customized information, fruitfulness of public information management, maintenance of management system for public mobile app service, user-friendly promotion appropriate in mobile environment, public mobile app development based on e-government standard framework, etc.. This study may provide the researchers with the successive study guidelines in mobile e-government and public mobile app fields. Also, the study may help the practitioners to make effective decisions on polices and strategies for mobile e-government of local government.

Since 2015, the government has been making efforts to distribute Korean smart farms. However, the supply is limited to large-scale facility vegetable farms due to the limitations of technology and current cultivation research data. In addition, the efficiency and reliability compared to the introduction cost are low due to the simple application of IT technology that does not consider the crop growth and cultivation environment. Therefore, in this paper, data analysis services was performed based on public and external data. To this end, a data-based target smart farm system was designed that is suitable for the situation of farms growing in facilities. To this end, a farm risk information notification service was developed. In addition, light environment maps were provided for proper fertilization. Finally, a disease prediction model for each cultivation crop was designed using temperature and humidity information of facility farms. Through this, it was possible to implement a smart farm data service by linking and utilizing existing smart farm sensor data. In addition, economic efficiency and data reliability can be secured for data utilization.

Due to the dramatic increase in usage of smart phones, mobile applications offer a promising public communication channel to effect behavioral change in areas such as energy saving. For this, identifying relationships between applications and behavioral change would be useful for public institutions to formulate more effective public communication strategies. Based on a design science approach, this study examines the effect of design factors of public service-oriented mobile applications such as personalization, accessibility, and representation richness on users' cognitive and affective attitudes. Their effects on behavioral outcome are also investigated. The results of the analysis show that most design factors contribute significantly to the cognitive and affective attitudes of users. In turn, cognitive attitudes affect users' behavioral change in terms of energy saving, while affective attitudes are positively associated with the average usage time of mobile applications and behavioral changes in terms of energy saving.

The purpose of this study was to identify the self-awareness of smartphone dependence among undergraduate students and their response to the same. The data was drawn from a survey on smartphone overdependence conducted by the Ministry of Science and information and communications technology (ICT) and the National Information Society Agency in 2017. The responses of 1,735 undergraduate students were analyzed by frequency, percentage, mean, standard deviation, minimum-maximum value, ��2-test, independent t-test, Pearson's correlation coefficient, and stepwise multiple regression analysis. The results indicated that 22.3% of participants were at risk of smartphone dependence, and 63.6% of them were unaware of their dependence on smartphones. The perception of smartphone dependence was significantly associated with a higher risk of smartphone dependence (��=.35, p=.000) and the increasing use of applications such as games (��=.19, p=.000), television/video (��=.11, p=.000), and learning (��=.11, p=.000). Of the participants with dependence awareness, only a few knew about the existence of centers to prevent smartphone and internet dependence. Moreover, they rarely utilized these centers. However, the participants felt the need for more counseling agencies (26.8%), programs for dealing with oneself (23.2%), information about smartphone dependence (14.9%), and help to overcome dependence (10.9%). These findings show the need to establish public services so that students can easily access correct information on smartphone dependence and address this problem.

Most public organizations which charge for measuring or collecting environmental information provide web-based information services. In the case of Seoul, it is provided smart phone app for information services on region or district unit. However, there is no smart phone application for environment information services considering location-based services with the concept of personalization. The purpose of this study is to deign and implement a smart phone app for air environment and radioactive information services with these features. Hybrid type is adopted, so that several things are possible: access to a variety of devices by web languages, and N-Screen support is available. According as social needs with respect to more environmental information and their contents are increasing, this approach will be useful.

In this study, we tried to provide basic materials necessary for introduction of smart libraries by analyzing present conditions of its operation based on the actual conditions of digital materials. For this study, a survey of actual use of digital materials is conducted for digital material rooms of public libraries in nationwide and 213 persons in charge of digital materials. As a result of this study, the followings are found: first, 80.8% of those public libraries responding to the survey operate digital material rooms and average 1.75 person is in charge of managing digital materials and open type Wi-Fis are installed in those public libraties but only 11.3% of those libraries provide 5G services; second, it is found that the digital data which are owned by those public libraries most are video contents (63.8%), e-books (53.5%) and audio books (53.5%) in order. In addition average number of types of audio books 781, video contents 4,985, nonbook contents except for video 3,616 and other digital data 626. This study is a basic research for introduction of smart library and it is necessary to conduct another study of a plan for future revitalization of digital materials and librarians' awareness on introduction of smart library.

The importance of 'Big Data' is increasing to the point that it is likened to '21st century crude oil'. For smart city IoT data, attention should be paid to quality control as the quality of data is associated with the quality of public services. However, data quality indicators presented through ISO/IEC organizations and domestic/foreign organizations are limited to the 'User' perspective. To complement these limitations, the study derives supplier-centric indicators and their priorities. After deriving 3 categories and 13 indicators of supplier-oriented smart city IoT data quality evaluation indicators, we derived the priority of indicator categories and data quality indicators through AHP analysis and investigated the feasibility of each indicator. The study can contribute to improving sensor data quality by presenting the basic requirements that data should have to individuals or companies performing the task. Furthermore, data quality control can be performed based on indicator priorities to provide improvements in quality control task efficiency.
