The purpose of this paper was to understand the mediating effect of academic achievement on the relationship between youth activity participation and career decision-making in middle school students. To this end, data from the KCYPS2018 (Korean Children and Youth Panel Survey 2018) were used, and this research proceeded with 2,471 middle school 1st grade students. This analysis method was a regression analysis to examine any mediating effect. And the findings are as follows. Middle school students' youth activities participation had a significant effect on career decision-making and academic achievement, and the effect of youth activities participation on career decision-making was mediated in part by academic achievement. Thus, a variety of youth activity programs should be developed and provided to middle school students to increase their motivation and academic achievement. Education and training for youth leaders and teachers should be provided to help middle school students make career decisions by operating youth activity programs in conjunction with the free semester system.

The purpose of this study was to explore how primary school students develop their interest in science. A survey questionnaire was used to investigate students' interest, change of their interest, and engagement in science related activities three times a year. 201 students of two primary schools in Seoul Metropolitan City initially participated in this study. A follow-up case study was conducted with students who showed an increased interest in science. Finally, seven students were chosen in the case study. They were asked to keep a photo journal for 12 weeks, and were interviewed in every other week by one of the researchers. Among these seven participants, two (TK and QQ) were chosen for analyzing their data in this case study because they showed positive changes in developing science interest throughout the study. The results of two participants' survey, photo-journal and interview were analyzed qualitatively. First, TK, whose science interest developed from situational interest II to individual interest I, engaged in doing experiments at home, doing mathematics activities, raising pets or plants, observing phenomena, and visiting informal educational centers. He tended to participate in hands-on activities by himself in out-of-school settings. Second, QQ who developed from situational interest I to situational interest II, engaged in taking pictures as a representative activity at home and school. He tended to participate in activities with either his father or one of the researchers. Both students showed personal characteristics such as doing place-based activities, interaction with others and activity subjectivity. The goal of TK's interactions with others on the various places was to develop in cognitive domain. On the contrary, QQ's goal of interactions with others was to develop in emotional communication. This study reported the cases of characteristics of students who developed their interests in science including activities in- and out-of-school settings and their accompanying people.

As the importance of software education is emphasized, various educations for improve the computational thinking of elementary school students are being provided. However, there are many limitations that apply to the school at preceding studies. because they were invented for specific environment or students. Therefore, in this study, software education was conducted by constructing teaching-learning activities in consideration of the characteristics of students such as teaching aids and level of computational thinking ability, which can influence students based on the contents of textbooks. Through the comparison about computational thinking improvements, this study tried to suggest the direction of effective software education method. As a result, there are differences in computational thinking improvements according to the student's level and used teaching aids. Specifically, visual programming and unplugged type teaching-learning activities were more effective in teaching aids, and according to the level of students, students with low level of computing thinking in pre-inspection showed relatively high improvement. This tendency suggests that it is necessary to consider various learning factors in designing teaching-learning activities in elementary software education.

A Monte-Carlo simulation method is proposed which can evaluate the target failure/safety levels on any failure modes of harbor structures as a function of central safety factor. Unlike the calibration method based on the average safety level of conventional design criteria, the target failure/safety level can be directly evaluated by only using central safety factors of the harbor structures which have been designed by safety factor method during the past several decade years. Several mathematical relationships are represented to straightforwardly connect the conventional safety factor design method with reliability-based design method. Even though limited data have been used in applying Monte-Carlo simulation method to sliding failure mode of the vertical breakwaters, it is found that target reliability indices evaluated by the suggested method in this paper is satisfactorily agreement with new criteria of reliability index of Japan.

The objective of this study is to examine whether there are differences in participation in social activities and the effects of social activity types on the levels of happiness of the Korean older adults by age groups. The 5th wave(2014) of the Korean Longitudinal Study of Ageing (KLoSA) was used and a total of 3,273 elderly were selected from the 5th wave, who were 65 years old and older and who were not living with their offsprings. Chi-square test, ANOVA, and hierarchical multiple regression analysis were used. The rate of participation in economic activities declined with age and the levels of participation in leisure activities was higher in the young-old group in comparison to the middle- and the oldest- old groups. The levels of participation in family activities was higher in the middle- and the oldest-old groups in comparison to the young-old group. Socializing activities and religious activities measured by the frequencies of activities were not significantly different among the age groups. The results of a regression analysis of social activity types and their effects on happiness by age groups are the followings: 1) Leisure, socializing, religious, and family activities all (with the exception of economic activities) significantly affected the level of happiness of older persons in the young-old group. 2) However, only socializing and family activities in the middle-old age group, and only family activities in oldest-old group, had a statistically significant impact on the levels of happiness. These results support that the rates of participation in the five types of social activities and their effects on the levels of happiness were different by age groups. The implication of this study was to report that needs and the interests of older individuals are different by age groups based on empirical evidences.

This study assessed the manner in which social activities, religious experiences, and spiritual practices related to depression and life satisfaction among 217 Korean elderly individuals, aged 65 to 80. The Social Activities Scale and Brief Multidimensional Measure of Religiosity/Spirituality were employed to assess social activities and six domains of religiosity/spirituality: daily spiritual experiences, values, forgiveness, private religious practice, religious/spiritual coping, and religious support. In addition, depression was assessed with the Geriatric Depression Scale, and life satisfaction with the Satisfaction with Life Scale. After controlling for demographic variables, lower depression scores were predicted by higher levels of religious and spiritual coping, social activities, higher income, and ower daily spiritual experiences. In addition, identifying as female, advanced old age, and lower social activities predicted lower life satisfaction in this study. The implications of this study's findings on social work practice are also discussed, along with some future research directions.

This study explores the effect of open innovation activities on innovation performance by dividing into two dimensions of breadth and depth of open innovation activity, and it also verifies the mediating effect of technical protection between open innovation activities and innovation performance. In order to examine the hypothesis, it has surveyed 1,403 companies of manufacturing and service with experience in producing innovative results. The results find that the breadth of open innovation activities has a positive effect on the achievement of radical innovation, and the depth of open innovation activities brings a positive effect on the achievement of incremental innovation. The verification result of the mediating effect of technology protection indicates that partially mediated between the breadth of innovation activities and radical innovation activities, and in the case of the depth, it is completely mediated. The results of this study provide the crucial implications not only for the company promoting open innovation, but especially also for the companies promoting product innovation by acquiring technology.

Purpose This study examines the roles of individual- and country-level social capital in entrepreneurial activities from the context of crowdfunding. Design/methodology/approach Two primary sources were used for data collection. From Kickstarter, the largest U.S.-based crowdfunding platform, this study obtained 15,716 crowdfunding projects and individual-level social capital. For country-level social capital, the social capital index from the 2016 Legatum Prosperity Index was utilized. By matching individual- and country-level social capital for each crowdfunding project, this research estimates the role of social capital in entrepreneurial activities at the individual and country level using the Poisson regression and the negative binomial regression. Findings Individual-level social capital measured by the number of Facebook friends, the number of other crowdfunding projects that a crowdfunding project founder invested in, and the word count of the description of a crowdfunding project are positively associated with the number of crowdfunding projects created by founders. The country-level social capital measured by aggregated social capital index is also positively associated with the number of crowdfunding projects created by founders. Both individual- and country-level social capital have a positive impact on entrepreneurial activities in terms of the creation of new crowdfunding projects.
