Social infrastructure facilities can be destroyed instantly when exposed to EMP (ElectroMagnetic Pulse), causing social chaos. However, concrete structures with low electrical conductivity cannot expect EMP shielding effect. Therefore, in this study, a metal sprayed thin film showing excellent EMP shielding performance was applied to a concrete structure to evaluate the metal spray welding efficiency and adhesion performance of the thin film according to the concrete surface treatment method. As a result according to the concrete surface treatment method, It was confirmed that the use of a roughening agent that generates physical irregularities in order to improve the welding efficiency and adhesion performance increases the physical performance of the concrete and metal sprayed thin film.

The ElectroMagnetic Pulse (EMP) destroys social infrastructure at once and causes social chaos. However, currently major infrastructures are constructed of concrete that does not have electromagnetic shielding performance. In this study, using the arc metal spraying method is used to evaluate the shielding performance and construction performance of concrete. The electro-magnetic shielding effect is measured by fabricating a shielding room with reference to MIL-STD-188-125, and the construction performance is evaluated by measuring the adhesion strength of thin metal sprayed film-concrete. As a result of the study, when the metal spraying method is applied, the shielding effect is higher than that of the special electro-magnetic shielding concrete, and it is considered to be more economical than the existing metal plate (3~5 mm).

we explored the case of 'H-Community', a private organization that supports alcohol-dependent homeless people living in the Jokbang village, based on the awareness that "the key to social assistance for alcohol-dependent homeless may be an influential relationship to replace the role of their families." The data collection and analysis followed the research that Spradley presented, and the result was 'living in the balance rather than the great affection'. However, the density of the relationship and emotional bond appeared different, which had something to do with their respective life processes and their health, age and economic conditions. These differences were categorized and suggested as arguments through 'a family-alternative relationship', 'emotional bond' and 'participation'. Based on the results, the conclusions presented the implications needed for alcohol-dependent homeless people.

The purpose of this study was to find ways to reduce old age anxiety by identifying the differences between old age anxiety, grandparents' connection, filial piety, and characteristics, and by identifying factors that affect old age anxiety. The study participants conveniently labeled college students residing in Seoul, Gyeonggi and Chungcheong provinces, and collected data from 2 April to 15 June 2018 and distributed a total of 250 structured questionnaires and retrieved 235 copies to use part 213 for the final analysis. The analysis used SPSS 20.0 Version to obtain frequency, percentage, average, and standard deviation, and age anxiety according to the characteristics of the subject, grandparents and sense of filial piety were analyzed with t-test and ANOVA, and the correlation between aging anxiety, grandparents' bond and filial consciousness was confirmed as Pearson correlation co-efficient. To check the effects of aging anxiety, polylinearity was diagnosed and analyzed with Stepwise multiple regression. Research found that there were statistically significant differences in age insecurity according to majors, grandparents and ties by gender and filial piety by religion and grandparents. And the lower the bond with grandparents, the higher the filial piety, the higher the anxiety was.

This paper examine the roles of social rapport and friendship which are the representative variables of strong emotional bonds between customers and firms in service relationship marketing. As results, social rapport and friendship were confirmed as positive moderators between a relational antecedent variable and a relational mediator variable. In other words, emotional bonds, such as social rapport and friendship, stimulated relationship development in service relationship marketing. Meanwhile, customer-firm emotional bonds seemed to be a negative effect on the stage of a relational mediator variable and a relational outcome variable. This meant that relational mediator variable and emotional bond variables(social rapport and friendship) individually had an positive effect on a relational outcome variable. If emotional bonds between customers and firms had already built, they could have positive influence on the relational outcome, regardless of relational mediator variables. Conclusively, firms' relational efforts focus on the building the emotional bonds with customers, not on the process of relational antecedents, mediators, and consequences.

Recently, urban tourism regeneration projects to attract tourists are gradually increasing. Therefore, this paper focuses on social capital, which is a major factor in attracting tourists to revisit for revitalization of such urban tourism areas. Specifically, it looked at one of the social relations formed between tourists and local residents,'the process of revisiting based on attachment to the place by making the formation of social capital perceive empirical value'. As a result, you can see (insert result). This means that the bond between tourists and local residents is an important factor in inducing tourists to revisit actively in the urban tourism regeneration area. Therefore, this study presented implications for academic and practical work based on these results.

This study intends to analyze the trend of employment rate of men aged 55~64 in 15 OECD countries from 1980 to 2005. Furthermore, this study means to examine the determinants of men aged 55~64 in 15 OECD countries to support the labor force participation among them. The analysis is based on the data of OECD, ILO and LIS. The analysis method is Arellano and Bond(1981)'s difference GMM which used instrumental variables by dynamic panel model which estimates state dependency of labor market participation and individual panel's heterogeneity. The main results from this analysis are summarized in three points. First, the employment rates of men aged 55~64 had decreased until the middle of the 1990s, while that has been increasing since 1995. Second, the sate dependency strongly worked in the employment rates of 55~64 men and positive period effect was observed for 1980~2005. This study cannot find the pull effect of public pension, while labor market push effect have negatively affected. Third, temporary work rates had contributed to increase the employment rate of men aged 55~64 for 1996~2005. The poverty has become the mechanism of the labor.
