Smart cars, which incorporate information and communication technologies (ICT) to improve driving safety and convenience for drivers, have recently emerged. However, the increasing risk of automotive cybersecurity due to the vulnerability of electronic control units (ECUs) and automotive networks, which are essential for realizing the autonomous driving functions of smart cars, is a major obstacle to the widespread adoption of smart cars. Although there have been only a few real-world cases of smart car hacking, drivers' concerns about the security of smart cars can have a negative impact on their proliferation. Therefore, it is important to understand the risk factors perceived by drivers and the trust in smart cars formed through them in order to promote the future diffusion of smart cars. This study examines the risk factors that affect the formation of trust in smart cars, focusing on security and privacy, and analyzes how these factors affect safety perceptions and trust in smart cars.

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.

One of the core policies recently implemented by the Korean government is the introduction of a creative economy, a concept that integrates ICT with the existing economic structure in order to create new growth factors and jobs. In June of 2013, the National Assembly passed a bill for the institutional practice of a creative economy. The concept of a creative economy is to integrate industries centered on ICT in order to form a new-concept industry paradigm that creates new values and services that exceed past industrial categories. In other words, smart convergence, which integrates ICT with various industries, is evaluated as a core factor for boosting the creative economy. Thus, based on the definition of 'smart convergence', this study predicted the economic effects and sociocultural changes that will ensue due to the future era of smart convergence. Also, this study proposes policies for enhancing the creative economy in various ways. More specifically, in-depth interviews with convergence industry experts were carried out and quantitative analyses were performed employing a Solow Model. Furthermore, as a means to revitalize the creative economy, this study underscores the significance of the preemptive institutionalization of legislations and suggests several policy proposals regarding smart convergence rooted in market supply and the demand chain, smart convergence through selective focus, and smart work. This study is differentiated from previous studies that have only focused in establishing theories in that it offers quantitative research with a consideration of the feasibility of proposed policies. The leading experience of Korea regarding smart convergence can provide important lessons to other countries that hope to promote a creative economy as a means to create new growth factors and jobs.

The fourth industrial revolution and so on, the manufacturing environment is based on the latest IT technology, and ICT-based convergence that links with various industrial fields is actively proceeding. For this reason, convergence security based on changing environment in the field of security is emerging as a new issue, and various demands for convergence security are increasing. Such changes in the industrial environment not only provide advantages of convergence environment, but also cause various fusion and complex security problems. In particular, the government is actively promoting policies to build 10,000 smart plants by 2020, and has implemented projects to build 2,800 smart plants from 2014 to 2016. Therefore, we will examine the security threats and countermeasures against smart factories that are being built on the basis of ICT rather than the existing closed type.

In this paper, we propose a smart meter that uses GRU model, which is one of artificial neural networks, for the efficient energy management. We collected power consumption data that train GRU model through the proposed smart meter. The implemented smart meter has automatic power measurement and real-time observation function and load control function through power consumption prediction. We determined a reference value to control the load by using Root Mean Squared Error (RMS), which is one of performance evaluation indexes, with 20% margin. We confirmed that the smart meter with automatic load control increases the efficiency of energy management.

Due to global population growth and urbanization, water problems are expected to increase in severity. In response to this expectation, Smart Water Management that refers to implement intelligent water information systems by IT convergence is considered a new paradigm. In this paper, we try to study the Smart Water policy, especially Smart Water Grid, and technology development trends in major countries. On the basis of results from the comparative analysis with Smart Grid in power sector, we evaluate political. legal, economic and technological feasibility related with the Smart Water Grid. In the conclusion, we suggest some strategic recommendations for the promotion of the Smart Water Grid.

The purpose of this study is to identify the factors affecting the adaptation, Self-esteem and self-control of college students to smart addiction. We surveyed 380 university students in Gwangju area. Data were analyzed by t-test, one-way ANOVA, Pearson correlation analysis. Smart phone addiction according to general characteristics showed the lowest in fourth grade and high in health-related majors. Smart phone usage time was the lowest in less than 3 hours due to the actual usage of smart phone. School life adaptation, self-esteem, and self-control according to general characteristics were higher in satisfaction with college life and majors. The most influential factors on the addiction of smart phone were perceived smart phone addiction, and the self-esteem and self-control were more likely to be addicted to smart phone. Therefore, it is necessary to develop education and programs to enhance self-esteem and self-control of college students and to find ways to prevent smart phone addiction.

본 논문은 국방 클라우드를 기반으로 병사 스마트폰 사용에 대한 거버넌스의 방안을 연구한다. 2020 년부터 군 부대 내에서 병사의 스마트폰의 사용이 전면 시행되었다. 하지만 대량의 병사 스마트폰을 인적자원을 통해 관리하기 때문에 많은 인적자원 리소스가 필요하고, 보안이 중요한 부대 특성상 보안 점검을 사유로 인권침해가 발생하고 있다. 따라서 군 부대 특성을 고려한 거버넌스를 정의하고 도입할 필요가 있다. VMI(Virtual Mobile Infrastructure) 시스템을 이용한 국방 클라우드 기반 스마트폰 관리 시스템은 스마트폰을 군 보급품으로 지급하고 모든 스마트폰 프로세스 및 데이터를 중앙 서버를 통해 관리한다. 본 논문에서는 국방 클라우드 기반 스마트폰 거버넌스를 정의하고 중앙 서버를 통해 모든 스마트폰의 프로세스와 데이터를 관리함으로써 얻을 수 있는 기대효과를 관리적, 보안적 측면에서 연구하였다.
