Using alumina-glass infiltrated material which has been in the spotlight of biomaterials including dental material, appropriate composition of glass infiltrated material mainly depends on the thermal expansion coefficient. To obtain proper compositional glass of suitable thermal expansion coefficient effiiently. a Taguchi analysis was conducted. The influence of alkali oxide and alkali earths oxide, which affect mostly the thermal expansion coefficient of glass infiltrated material, was infiltrated material, the effect having influenced on the thermal expansion coefficient of glass was presented in this order (Na$_2$O≫K$_2$O ≫MgO≒CaO). The effect of Na$_2$O was about eight times as great as the effects of MgO, CaO and $K_2$O was about four times. Among the interaction affects of each variables the interaction affects of $K_2$O-CaO showed most significantly and thermal expansion property of specified composition was predicted by calculating contribution rate on each level of variables and interaction affects.

Most people seek a happy life and happiness positively affects sentiment, satisfaction with life, creativity, human relationship, business productivity, and even health and life extension. However, according to a survey in 2013, subjective happiness of adolescents (including university students) was very low compared to other age groups in Korea. Therefore this paper examined the effects of job-seeking stress, appearance recognition, financial situation, trust in government, and locus of control on university students' happiness using SEM (structural equation modeling). 207 university students in Seoul, Korea have been surveyed. At first, an initial experimental SEM model among these variables has been set up and reliability analysis has been conducted. Then multiple regression analyses on job-seeking stress and happiness as well as SEM analysis have been conducted. As a result of these analyses, the SEM model has been revised two times. The final SEM model passed the goodness-of-fit test (using RMR, GFI, NFI, CFI, and IFI indices). The final SEM model showed the followings. First, Higher job-seeking stress (especially sentimental part, rather than environment or action related parts) negatively affects happiness. Second, Trust in government also affects happiness both directly and indirectly. Third, Locus of control is affected both by trust in government and financial situation. Fourth, appearance recognition heavily affects job-seeking stress. In addition, appearance importance is higher than appearance interest, meaning that students who are not very interested in appearance usually recognize the importance of appearance. Finally, happiness is affected neither financial situation nor appearance recognition. Therefore, even either they are in a poor financial situation or not happy with their appearance, they can be happy if they have firm locus of control.

Objective: The purpose of this study was to examine the parallel dual mediating effects of positive and negative affects in the relationship between adult attachment and self-compassion of teachers in the early childhood education and care centers. Methods: Two hundred and six teachers participated in the survey who were recruited from kindergarten and child care centers in Seoul and five provinces in South Korea. The data were analyzed by means of frequency, percentages, Cronbach's reliability coefficient and Pearson's correlation using SPSS 25.0 and model 4 provided in The PROCESS macro for SPSS 3.4 version. Results: First, the teachers' degrees of anxiety and avoidance in their adult attachment were below the median scores. Those of positive and negative affects, and their self-compassion were close to the median scores. Second, there were parallel dual mediation effects of positive and negative affects between anxious attachment and self-compassion of teachers. Meanwhile, only positive affect had a mediating effect in the path of teachers' avoidant attachment and self-compassion. Conclusion/Implications: This study confirmed that it is important to raise positive affect by lowering each level of anxiety and avoidance in their attachment for teachers in order to improve their self-compassion. It implied the need to provide support for attachment stability enhancement and to pay attention to improve their self-compassion.

Purpose - Brand equity has emerged as an indispensable marketing tool for firms engaging their business in developing nations. This study proposes that the country of origin image and advertising will affect the Korean brand equity formation, which leads to repurchase intention of Korean brands. In the study, attitude factors are applied in brand equity theory to predict repurchase intention of Korean brands. Cognitive brand equity, such as brand awareness, brand association, brand image and attitudinal brand equity, such as perceived quality and brand loyalty are considered with regards to their attitude towards the Korean brand. Design/methodology - A total of 178 Myanmar consumers out of 200 participants who have used Korean brands answered the survey and data were analyzed through SmartPLS 3.3.2 version. PLS-SEM is considered a more suitable analysis to pin down and evaluate the cause-effect relationship among all of the constructs with relatively complex models. Findings - Our results substantiate that the country of origin image positively affects brand awareness, brand associations, and brand image and advertising awareness positively affects brand awareness. Brand awareness gives positive effect only on brand association, which sustains a positive effect on brand image and brand loyalty. Brand image only has a positive effect on perceived quality, which again affects repurchase intention and brand loyalty. Brand loyalty also shows a positive effect on repurchase intention. Originality/value - Brand equity dimensions were viewed as cognitive and attitudinal outcomes of brand equity which affects repurchase intention. The drivers of brand equity were considered from the perspective of country of origin image that firms cannot control or mange, and advertising awareness which firms can control and manage. The findings also explored the relationships between cognitive and attitudinal brand equity.

Purpose: The purpose of this study is to examine the mediating effect of children's perceived peer attachment on children's subjective well-being and the effects of self-esteem, one of the variables of individual personality characteristics, on peer attachment and subjective well-being. Design: Data from the 2018 Panel Study on Korean Children were used. Methods: The survey method was conducted by the investigator, and the total number of cases was 1,434 people. Results: First, the higher the child's peer attachment leads to higher subjective well-being and self-esteem, and the higher the self-esteem leads to higher subjective well-being. Second, in the relationship between peer attachment and subjective well-being, self-esteem acts as a mediator variable. Third, children's peer attachment affects subjective well-being and self-esteem, and self-esteem affects subjective well-being. The results explain that the degree of children's peer attachment itself affects subjective well-being and self-esteem, and self-esteem also affects children's subjective well-being. Conclusion: Self-esteem is an important factor influencing subjective well-being and has a mediating effect on the relationship between peer attachment and subjective well-being. In other words, it can be understood that children feel subjective well-being through positive interactions with peers, not only in parent relationships. Based on these results, it is necessary to suggest practical interventions to enhance children's subjective sense of well-being and to develop various programs that can strengthen the sub-factors of peer attachment.
