Recently, research and system using AI is rapidly increasing in various fields. Smart farm using artificial intelligence and information communication technology is also being studied in agriculture. In addition, data-based precision agriculture is being commercialized by convergence various advanced technology such as autonomous driving, satellites, and big data. In Korea, the number of commercialization cases of facility agriculture among smart agriculture is increasing. However, research and investment are being biased in the field of facility agriculture. The gap between research and investment in facility agriculture and open-air agriculture continues to increase. The fields of fruit trees and plant factories have low research and investment. There is a problem that the big data collection and utilization system is insufficient. In this paper, we are proposed the system for determining the fruit tree growth stage using a deep learning-based object detection model. The system was proposed as a hybrid app for use in agricultural sites. In addition, we are implemented an object detection function for the fruit tree growth stage determine.

In this paper, I analyzed the cause on difference of ICT literacy level according to region scale in elementary school. According to precedent research, ICT literacy score of elementary student in 2016 were higher in order of big city, small city and rural area. To find the cause of difference by region scale, I compared ICT literacy score and ICT use habit. As a result, The cause for this is that students in large areas have more chances to use computers at home, learn more with computers, and have more information (computer) education than students in small areas appear. Therefore, Based on the results of this study, I proposed methods to reduce the regional ICT literacy score difference. The methods are to provide computers for low-income students, to guide learning methods using computers at home, and to provide more computer education opportunities.

The purposes of the study was to investigate BYOD (Bring Your Own Device) policy since it would be limited to distribute all of the digital devices required for the schools within the budget of the government. First, the concept and characteristics of BYOD were introduced. Then, the pros and cons of BYOD were analyzed according to the case studies of BYOD policies of the U.S. Based on the previous experiences, guidelines of domestic BYOD policies were established. Regarding the institutional aspect, technical issues, usage, damages, digital divide, information security, and resources were discussed. Additionally, conditions of technology, networks, filtering, software were also considered as essential infrastructure. In sum, as an alternative of distributing digital devices in schools, the importance of BYOD should be regarded as top priorities with systematic preparations in launching digital education. It would be expected that this study play a fundamental role in launching domestic BYOD policy by supporting specific strategies.

The level of ICT in the country affects economic performance as a basic infrastructure that has a significant impact on the competitiveness of the country. With the proliferation of globalization, ICT-related economic activities such as electronic trade are becoming more active, and the importance of ICT in the country is increasing. This study sought to analyze the impact of ICT level on the economic performance of the nation by subdividing it into three dimensions: accessibility, usage, and utilization skill. In particular, we sought to find ways to effectively resolve the digital divide between developed and developing countries by analyzing the difference in economic impact of ICT level. Furthermore, we tried to verify whether the government regulation and firm's nature of competitive advantage in the international markets play a moderating role in the economic impacts of ICT in the country. As a result of panel analysis with data collected from ITU, WEF and World bank national ICT level has consistently significant influence on economic growth in terms of access and usage. In addition, it was confirmed that the competitive advantage of companies in developed countries and the government regulation in developing countries have a significant moderating effect on the relationship between ICT level and economic growth.

This study investigates the current features of social service provision system focusing on the core institutional traits of the system and community environment. Specifically, the study analyzes the differences in the contents and characteristics of social service provision, according to the community types, such as metropolitan area, medium size cities, and rural area. Also, the study explores the relationships among the three major subsystems in the social service provision system based on the types of financial provisions. Furthermore, the interaction effects between the community factors and financial traits on the relationships among sub- components in the service provision system are investigated. In this study other organizations, service users and public sector are regarded as three major sub-components in the provision system. The study utilizes the raw data from '2015 Social Service Demand and Provision Survey', which interviewed 4,100 social service organizations. Results from analyses show that the gap among metropolitan area, medium cites, and rural area is not so much bigger in the diverse provision features(e.g. the competition level, the major focus on the users, and policy demands on public sector) of provider-provision-organizations than in those of both of user-provision-organization and of market-way-organizations. User-provision organizations show the distinct differences in terms of the focus points on the users, while marketed organizations do in terms of the policy demands to the public sector. In rural area, user-provision organizations act like provider-provision-organizations whereas they do market-way-organizations in the urban area. Research findings show that the social service provision types utilizing market mechanism(such as user-provision, and market-way) are not so well fit into the characteristics of rural area.

This study aims to verify the mediating effect of social support in the relationship between online social relations service utilization(PC, mobile) and life satisfaction for middle-aged and Older Adults. For this purpose, the '2017 Digital Devide Survey' data collected by the National Information Society Agency was used, and among 2,300 middle-aged and Older Adults aged 55 or older, 1,488 people using the Internet were selected as the final analysis target. Then, using the structural equation, the mediating effect of social support was verified in the between online social relations service utilization and life satisfaction. As a result, it was verified that higher levels of mobile-based social relations service utilization have a positive effect on social support and life satisfaction. Also, it was confirmed that social support has a mediating effect in the relationship between the utilization of mobile-based social relations service and life satisfaction. However, the utilization of PC-based social relations services did not show to affect social support and life satisfaction. Therefore, the results of this study can be used as basic data for practical measures to increase the connection between mobile-based social relationship service education and social support promotion education for middle-aged and Older Adults. In addition, the study is meaningful in that it overcomes the limitations of measuring the use of online social relations services as one, and selects tools that are practically effective by dividing them into mobile and PC.
