This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

Here we analyze a case of redesigned course named "Prospect of Nuclear Engineering" as an example of student-entered education which came to the fore of university education innovation. This course was reformed from lecture-based to student-centered class by changing the context as follows: Stimulating students by addressing various problems or episodes behind scientific and mathematical concepts in the history; Offering experimental project to perceive the importance of differential equations; Exploring the research status and issues of nuclear engineering and the ways of attacking them by discipline; Discussing the public acceptance of nuclear power plants. Small group activities using 'small group discussion' and 'peer-learning' have been applied in this course to enhance students' critical and creative ability. In the survey, students rated highly in the fact that they could actively interact with the peers and that they could think for themselves through 'small group discussion' and 'peer-learning' which is not just the way of conveying knowledge.

In Korea, the government introduced the $6^{th}$ industrialization policy for the agricultural sector in 2013, to increase farmers' incomes and the value-added of agricultural products. Although some research has been done on the $6^{th}$ industrialization of agriculture, the relationship between the level of consumers' awareness and the $6^{th}$ industrialization of agriculture has not yet been discussed. The purpose of this paper is to analyze the effect of consumers' awareness levels on the development of the $6^{th}$ industrialization of agriculture. The results of a survey and seemingly unrelated bivariate probit model present the following findings: an increased consumers' awareness of the $6^{th}$ industrialization of agriculture positively affects the agricultural sector. More particularly, it was found that consumers who agree that the $6^{th}$ industrialization increases farmers' income and creates value-added agricultural products will also have an optimistic prospect for a successful $6^{th}$ industrialization. In addition, consumers who like to experience agro-tourism type activities give higher scores to the infrastructure level of the $6^{th}$ industrialization. Consumers who think that production section should take lead the $6^{th}$ industrialization of the agricultural sector will also have an optimistic prospect for a successful $6^{th}$ industrialization. However, consumers who think that farmers or farmers' organizations, should take lead the $6^{th}$ industrialization have a more pessimistic prospect for a successful $6^{th}$ industrialization. Consumers who got information on the $6^{th}$ industrialization from the internet think that the infrastructure of the $6^{th}$ industrialization is not good enough.

This study attempted to explore how middle aged married men and women prospected a Centenarian society and what implications their prospect cast for family policy. We conducted focus group interviews with five groups in order to identify their subjective prospects on marital relations, parent-child relations, caregiving from family or institutions, and alternative living arrangement. From those interviews, we found that married men and women in their 40s, 50s, and 60s possessed ambivalent attitudes toward their marital relationship, either acknowledging an importance of marital relationship or accepting long-standing disrespectful marital relationship. They also had a dualistic perspective on parent-child relationship, accepting parental responsibility for children and even grand-children but maintaining low expectations for children. What they needed was age appropriate opportunities for work or leisure and better community services and facilities. These results showed that the middle-aged was concerned experiencing unprecedented family situations. They needed family life education and services in order to adapt to the Centenarian society. Since family policy has viewed this age group out of service target, programs and services have been underdeveloped for this group. Expecting a Centenarian society however, we need to expand the boundary of family policy and take a new perspective. We need to develop and implement marital education programs, community-based self-care services, and age-appropriated opportunities for work, leisure, and social relations.

Purpose - In the present study, it has become the most important necessity in our daily lives that consumers' psychological factors affect the use of smartphones, and it has been analyzed through behavioral economic approaches. In this respect, the present study is intended to apply the heuristic theory and the prospect theory among behavioral economics theories to examine how psychological factors affect consumers' product selection. Research design, data, and methodology - In the present study, using smartphone repurchase as a dependent variable, whether regulatory focus effects have interaction effects on behavioral economic theories and behavioral economic effects such as possession (ownership) effects, framing effects, and brand recollection. As an analysis method, questionnaire surveys conducted with university students in Incheon were examined through Two-Way ANOVAs using the SPSS23 package. Results - The analysis from the results are as follows. Using smartphone repurchase as a dependent variable, the main effects and interaction effects on two variables; satisfaction difference with product functions and positive framing variable were statistically significant. Using repurchase as a dependent variable was statistically significant, there was no interaction effect between the two variables; satisfaction difference with product functions and the difference of brands in possession. Using smartphone repurchase as a dependent variable, interaction effects on two variables; satisfaction difference with product functions and the lengths of product possession periods were not statistically significant. The results from the analyses of interaction effects of brand recollection and brands type were statistically significant in possession using repurchase as a dependent variable. The results from the analyses of the main effect of the brands type were statistically significant in possession using repurchase as a dependent variable. Conclusions - The implication of the present study is that it suggests the factors that became important for customers' smartphone purchase following the change in the meaning of smartphones from practical products in the past to hedonic products. Limitations of the present study are first, the study subjects are limited to students and the number of copies in questionnaires is only approximately 130, which is insufficient, so that the present study is not sufficient as a study for entire smartphone users.

Irrational ordering decisions of supply chain members have been gaining growing importance in the area of supply chain management. Irrational ordering behaviors that deviate from the profit maximizing decisions in the newsvendor settings have observed with human experiments in recent research. These behaviors can be modeled with several typical decision bias elements. This bias in ordering decisions affects the performance of supply chain contracts designed based on the assumption that the supply chain members make optimal decisions, making it necessary to design supply chain contracts by considering the irrationality. The purpose of this research is to derive a method to design the revenue sharing contract that considers human irrationality in ordering decisions. This research considers a simple two-echelon supply chain consisting of one supplier and one retailer, where the supplier is assumed to be perfectly rational while the retailer making newsvendor type ordering decisions displays irrational ordering behaviors. Under this environment, this research analytically models the revenue sharing contract to maximize the total supply chain profit or the supplier's own profits while considering the three decision bias patterns of the retailer, which include the pull-to-center effect, the prospect theory, and the increased subjective sensitivity to the revenue sharing ratio. Irrationality parameters are measured through human experiments based on which and through numerical simulations, we showed that significant improvements in the supply chain performance can be achieved.

The current status and prospect of decommissioning technology development at KAERI are reviewed here. Specifically, this review focuses on four key technologies: decontamination, remote dismantling, decommissioning waste treatments, and site remediation. The decontamination technologies described are component decontamination and system decontamination. A cutting method and a remote handling method together with a decommissioning simulation are described as remote dismantling technologies. Although there are various types of radioactive waste generated by decommissioning activities, this review focuses on the major types of waste, such as metal waste, concrete waste, and soil waste together with certain special types, such as high-level and high-salt liquid waste, organic mixed waste, and uranium complex waste, which are known to be difficult to treat. Finally, in a site remediation technology review, a measurement and safety evaluation related to site reuse and a site remediation technique are described.
