The purposes of this study were to examine the characteristics of friendship among the elderly, particularly the relationships between the functions of friendship, the degree of satisfaction with friendship, and subjective well-being. Written questionnaires completed by 244 the new-elderly(95men, mean age 60.02 years/ 149women, mean 62.04 years) were analyzed. As a result, the main findings of our study were: First, Among men, the duration of friendship was longer than among women. The most common initial acquaintance among men were co-workers, followed by schoolmates and old playmates, while friends made through leisure and volunteer activities or in the neighborhood were more common for women. Second, Factor analysis revealed the following two factors: 'trust and support', and 'companionship'. Among both men and women, the degree of satisfaction with friendship was positively correlated with subjective well-being, and the study suggested that the level of 'trust and support' influenced the degree of satisfaction with friendship. And expand the scale, because the future looked at the gender gap in the center is considered that there is a need for comparative studies specific age groups.

A fretting wear experiment in roam temperature air was performed to evaluate the wear mechanism of fuel rod using a fretting wear tester, which has been developed for experimental study, The main focus was to compare the wear behaviors of fuel rod against support springs with different contact contours (i.e. concave and convex). Wear volume, degree or surface hardening and adhesion tendency of wear particle were examined by the surface roughness tester. The result indicated that with a change of contact condition from contact force of 5 N to 0.1 mm gap, the wear volume of tube increased in the condition of concave spring, but slowly decreased in convex spring. From the results of SEM observation, wear mechanism of each test condition was also dependent on the spring shapes. The wear mechanism of each test condition in room temperature air is discussed.

This study was conducted to make a policy proposal for Korean grandparent-grandchildren families, analyzing what adversities adolescent grandchildren suffer when living in a grandparent-grandchild family, the types of Korean families and how family resilience appears as family power. In order to conduct this study, 20 consenting adolescents were selected for an interview from grandparent-grandchildren families recommended by the U City Healthy Family Support Center. This study suggests the following conclusions. First, we discussed divorce, death, financial bankruptcy related stress, economic difficulties in the present family, accidents involving family members of a grandparent-grandchild family, grandparents' serious disease, death, family conflicts and family comparisons with friends. Second, in the domain of family resilience, desire to maintain the family appeared as a Korean value. In addition, efforts to bond as an emotional family and grandchildren's attitudes of gratitude to grandparents are also expressed. However, family conversation appears weak due to the generation gap between adolescents and grandparents or complications from family stress. Third, the resilience in the family organization appeared weak since there are relatively insufficient socio-economic resources to support the family. This study makes several suggestions for family policies and shows the necessity to develop policies that reflect the needs of grandchildren and grandparents.

This is the third series of article on dental occlusion and relationship to TMD and systemic symptoms. In this part of the series, it will overview the theory, treatment methods, criteria, their limitation of Chirodontics, Dental Distress Syndrome (DDS) and quadrant theorem(QT). Chirodontics has its root on Chiropractic and to maintain the 'healthy status' of TMJ with stable occlusion via dental treatment. Dental distress syndrome on the other hand believes that all the TMD has originated from reduced or collapse of posterior support and incorrect posterior vertical support had caused imbalance of the head and neck structure which eventually affect the whole body symptoms. The analysis and treatment is planned using quadrant theorem where the position of head, rotatory pivot point and occlusal plane is analyzed.

Purpose: The study was done to identify variations in Nurses' CPR knowledge, attitude and performance before and after BLS Education. Method: This study was designed to evaluate the differences in Nurses' CPR knowledge, attitude and performance. For the study we selected 167 nurses working in Daegu K University hospital. The study group was given a test before (pre test) and after (post test) BLS education. The BLS education was given by two BLS instructors certified by the American Heart Association, using a DVD and manikin. Result: The results showed a statistically significant difference the nurse's knowledge, belief, emotion and performance but there was no significant difference in their behavior after BLS education. CPR knowledge and performance was higher among emergency room nurses compared to surgical ward nurses. Conclusion: CPR education has shown to have a positive effect on nurses' attitudes towards CPR. It also improved their related knowledge and performance. Therefore, cardiopulmonary education should be given continuously, and different steps of CPR education programs need to be developed in order to fill the knowledge deficiency gap.

This paper aims to explore instructional design of a cyber classroom for secondary students' basic English language competence. A paucity of support for low or under achieving students' English learning exists particularly at the secondary level. In order to bridge the gap, there has been demand for online educational resources considered to be an effective tool in improving students' self-directed learning and motivation. This study employs a comprehensive approach to instructional design for the asynchronous cyber classroom with the underlying premise that different learning theories can be applied in a complementary manner to serve different pedagogical purposes best. Gagné's conditions of learning theory, Bruner's constructivist theory, Carroll's minimalist theory, and Vygotsky's social cognitive development theory serve as the basis for designing instruction and selecting appropriate media. The ADDIE model is used to develop online teaching and learning materials. Twenty-five key grammatical features were selected through the analysis of the national curriculum of English, being grouped into five units. Each feature is covered in one cyber asynchronous class. An Integration Class is given at the end of every five classes for synthesis, where students can practice grammatical features in a communicative context. Related theories, pedagogical practices, and practical web-design strategies for cyber Basic English classes are discussed with suggestions for research, practice and policy to support self-directed learning through a cyber class.

This paper understands small and medium-sized enterprises(SMEs) with the lenses of 'labors' and 'technology' and analyzes possible alternatives for creating jobs in Korea. Interviews with eighty CEOs, directors, managers are conducted during the summer in 2017. In terms of 'labors,' critical issues were 'low income' and 'income gap from conglomerates.' When it comes to 'technology,' support for R&D was critically presented. This study proposes three policies for creating jobs: 1) National Management for Good Technicians, 2) Technical Bidding System, and 3) Mutual benefit disclosure System. Implications for the employment policy are followed.

This study analyzes factors that determine the usage of digital information by senior consumers in the mobile environment. Senior consumers are alienated from digital information in South Korea; therefore, there have been increasing attempts to resolve this digital divide and reduce the digital information usage gap between young adults and senior consumers. The study used panel data from the National Information Society Agency (2017); there were 1,463 participants, aged 50-79 years. SPSS 19.0 was used to conduct the statistical analyses for frequency, factor analysis, Cronbach' ${\alpha}$ analysis, descriptive analysis and hierarchical multiple-regression analysis. The results are as follows. First, negative attitude toward information society negatively influenced the mobile digital information usage in diversity context. Second, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & Mobile, and family support positively influenced the mobile digital information usage in diversity context. Third, negative attitudes toward information society negatively influenced the mobile digital information usage in quality context. Forth, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & mobile, and family support positively influenced the mobile digital information usage in quality context. The study results can help further understand mobile usage behaviors among senior citizens and the implications on their quality of life in the digital information era.

This study aims to identify the factors supporting and inhibiting the digitalization of blue economy MSMEs in Bitung, Indonesia. The literature shows little research on digitalization related to the blue economy in Southeast Asia, especially in Indonesia. This indicates that there is a large research gap related to digitalization and the blue economy in the Indonesian context. Data was collected through the distribution of questionnaires with open-ended questions to blue economy MSMEs. Data was also obtained from in-depth interviews with representatives of Aruna, an Indonesian company that focuses on simplifying the supply chain of fishery products by connecting small-scale fishers to the global market through technology. According to the study's findings, two primary factors-motivation to develop their business and efforts to maintain seller-buyer interaction-support SMEs' use of technology in the blue economy. However, digital literacy and technological infrastructure, such as the internet network, are the two main factors that become obstacles in the effort to digitize MSMEs in the blue economy. The role of the government is also a contingent factor that can strengthen the relationship between factors that support digitization and weaken the relationship between factors that hinder digitalization.

This study was conducted to identify the structural performance of the opening in a location close to the support point in the perforated beam system of steel beams. In addition, structural performance was determined through experiments on reinforced openings using vertical and horizontal steel plates. In the steel simple beam, it was found that the opening was in a position closer to the support point, half the height of the steel beam (D/2), which was more appropriate than the height of the steel beam (D). In addition, the reinforcement effect of horizontal steel plate was greater than that of vertical steel plate reinforcement. Structural performance was improved when there was no gap between openings and steel plates.
