The purpose of this study was to investigate the effects of personal, family, and job characteristics on married male postal delivery workers' overall life satisfaction. For this purpose, we surveyed 263 married male postal delivery workers between October 1st to 21st, 2008, and analyzed the data with multiple regression analysis. The results of this study were as follows: First, postal workers earned a low level of income, and their quality of health was not good relative to their age. They had severe work-family conflict, but could support and communicate with colleagues well. Second, even though they felt little opportunities and difficulties in lives, they moderately satisfied with everyday lives. Third, 43% of their satisfaction was explained by personal, family, and job related variables. Levels of workfamily conflict (${\beta}=-.31^{***}$), work support with colleagues (${\beta}=.25^{***}$), family sharing time (${\beta}=.14^*$), and health (${\beta}=.12^*$) were especially important variables affecting their satisfaction.

The number of single-person households is increasing every year, and there are also high concerns about the crime and safety of single-person households. In particular, crimes targeting women are increasing. Although home surveillance camera applications, which are mostly used by single-person households, only provide intrusion detection functions, this service utilizes AI image recognition technologies such as face recognition and object detection to provide theft, violence, stranger and intrusion detection. Users can receive security-related notifications, relieve their anxiety, and prevent crimes through this service.

At present, we are at the point of change of the 4th industrial revolution era due to the development of artificial intelligence(AI) and rapid technological innovation that no one can predict until now. This study started from the question of 'What role should home economics education play in the era of the Fourth Industrial Revolution?'. The Fourth Industrial Revolution is characterized by AI, cloud computing, Internet of Things(IoT), big data, and Online to Offline(O2O). It will drastically change the social system, science and technology and the structure of the profession. Since the dehumanization of robots and artificial intelligence may occur, the 4th Industrial Revolution Education should be sought to foster future human resources with humanity and citizenship for the future community. In addition, the implication of education in the fourth industrial revolution, which will bring about a change to a super-intelligent and hyper-connected society, is that the role of education should be emphasized so that humans internalize their values as human beings. Character education should be established as a generalized and internalized consciousness with a concept established in the integration of the curriculum, and concrete practical strategies should be prepared. In conclusion, home economics education in the 4th industrial revolution era should play a leading role in the central role of character education, and intrinsic improvement of various human lives. The fourth industrial revolution will change not only what we do, or human mental and physical activities, but also who we are, or human identity. In the information society and digital society, it is important how quickly and accurately it is possible to acquire scattered knowledge. In the information society, it is required to learn how to use knowledge for human beings in rapid change. As such, the fourth industrial revolution seeks to lead the family, organization, and community positively by influencing the systems that shape our lives. Home economics education should take the lead in this role.

Recently, the era in which various services using smart devices are used is sometimes referred to as the so-called "smart era". Among these, Smart Home Service' have not only brought about significant changes in the residential environment and culture, but are evolving very rapidly. and The 'Smart Home Service' provides more convenient services to users through communication between various electronic products in general homes, and has a bright future in the future. In particular,'Smart Home Service' provides various services combined based on IoT(Internet of Things) technology and wired/wireless communication in connection between various devices. However, such a "smart home service" inherits the security vulnerabilities of the underlying technologies such as the Internet of Things and wired and wireless communication technologies, and accidents that lead to the leakage of personal information and invasion of privacy continue to occur. So, it is necessary to prepare a countermeasure and prevention against the weak factors of the underlying technologies. Therefore, this paper is expected to be used as basic data for future application technology development and countermeasure technology by examining various security vulnerability factors of 'Smart Home Service'.

This study discusses the conceptual meanings of 'healthy families' by examining four popular misunderstandings regarding the concept. These misunderstandings are based partly on the lack of consensus on the use of the concepts of 'health' and 'families' and partly on the intentional misreading of the 'Healthy Fanulies Act' To correspond to the Concerns related to the Act, we need to clarify various meanings of the concept of family and to confirm the theoretical pounds of 'healthy families' based on the multidisciplinary consensus. To build consensus, it might be necessary to review some of the articles of the Act that have been misinterpreted.

Internet of Things is an infrastructure of the interconnected devices. In Internet of Things environment, many smart devices are used in daily life. It requires a new retrieval method using multiple devices. We propose an information retrieval method using both device characteristics and device usage characteristics in multi-device environments. Firstly, information retrieval is performed using a general purpose device. And then, it is performed using dedicated devices. Our method uses both characteristics of the devices and usage characteristics of them. Moreover, it considers queries on the general purpose device. This paper proposes a new retrieval method and describes algorithms. Then, it presents smart home scenarios. Performance evaluation is performed using the scenarios. The evaluation results show higher precision and efficiency than previous researches. The proposed method gets information more accurately and quickly in IOT multiple device environments.

This study investigated consumer innovativeness by examining a relationship model of innate innovativeness, product interest, product-specific innovativenss, and actualized innovativeness for eight product items as well as observed gender differences in the variables. The eight product items for the survey were smartphones, movies, clothing, cars, skin care products/cosmetics, traveling, AI products, and books. An online survey was conducted in January 2018, and 400 responses from male and female consumers in their twenties and thirties, were analyzed using reliability test, descriptive statistics, regression, and ANCOVA. The positive effect of innate innovativeness and product interest on product-specific innovativeness, and positive effect of innate innovativeness and product-specific innovativeness on actualized innovativeness were confirmed. Product interest was found to have a stronger power on product-specific innovativeness than innate innovativeness. Gender differences in product interest, product-specific innovativeness, and actualized innovativeness were identified as hypothesized. Female consumer's clothing interest, clothing innovativenss, and actualized clothing innovativeness were higher than male consumers; in addition, male consumer's cars and AI interest, cars and AI innovativenss, and actualized cars and AI innovativeness were higher than female's. The controversial results that indicated the higher innate innovativeness of male consumers useful to further in-depth discussion and research. This study contributed to the theory construction of consumer innovativeness research areas and offered practical implications for new product launching and customer relationship management.
