The purpose of this research is to 'know what causes the social isolation felt by marriage immigrant women'. Thus, a total of 253 cases of marriage immigrant women who use Multi-cultural Family Support Center in D city have been analyzed. The findings reveal that the factors influencing the sense of isolation in the social environment, experienced by immigrant women married to Koreans are: social support, family relationships, self-esteem, household income and economic activity. In other words, their strong sense of isolation from society will be lessened when they get more social support, are happy with their family relationships, have their improved self-esteem, earn higher household incomes and don't take part in undesirable economic activities. Based on the research results, this study makes suggestions, on both a political and practical level, to solve the above problem of social isolation faced by marriage immigrant women through their financial stability, desirable economic activities, healthy family relationships, the enhancement of self-esteem and the provision of generous social support for them.

In this paper, Asynchronous Self-Power Gating technique (ASPG) is used to reduce consumption power in asynchronous digital watch application. The power gating control signal is automatically generated by internal system operation characteristics instead of using replica circuit delay or four-phase handshaking protocol. Isolation cell is designed to insert it between power gating domain and normal operation domain. By using self-power gating circuit, asynchronous digital watch application consumes very low power and maintains data during sleep mode. The comparison results show the proposed ASPG technique saves leakage power up to 40.47% and delay time is reduced to 71% compared to the conventional circuit.

Shape memory alloy (SMA)-based Superelasticity-assisted Slider (SSS) is proposed as an engineering solution to practically exploit the well-accepted advantages of both sliding isolation and SMA-based recentering. Self-centering capability in SSS is provided by austenitic SMA cables (or wire ropes), recently attracting a lot of interest and attention in earthquake engineering and seismic isolation. The cables are arranged in various novel and conventional configurations to make SSS versatile for aseismic design and retrofit of structures. All the configurations are detailed with thorough technical drawings. It is shown that SSS is applicable without the need for Isolation Units (IUs). IUs, at the same time, are devised for industrialized applications. The proof-of-concept study is carried out through the examination of mechanical behavior in all the alternative configurations. Force-displacement relations are determined. Isolation capabilities are predicted based on the decreases in seismic demands, estimated by the increases in effective periods and equivalent damping ratios. Restoring forces normalized relative to resisting forces are assessed as the criteria for self-centering capabilities. Lengths of SMA cables required in each configuration are calculated to assess the cost and practicality. Practical implementation is realized by setting up a small-scale IU. The effectiveness of SSS under seismic actions is evaluated using an innovative computer model and compared to those of well-known Isolation Systems (ISs) protecting a reference building. Comparisons show that SSS seems to be an effective IS and suitable for earthquake protection of both structural and non-structural elements. Further research aimed at additional validation of the system are outlined.

The purpose of this study is to investigate children's perceptions of their own peer status and the variables that affect the perception. Four hundred boys and girls in grades five and six participated in this study. The participants were sampled from elementary schools located in two cities in Cheon-buk Province. Out of the 400 self-report questionnaires filled by the participants, 380 were used for the data analyses. The methods of analyses included basic descriptive categorical analysis (frequencies, means, percentages) as well as t-test, one way ANOVA, and multiple regressions. To summarize major findings from the analyses; first, a significant difference was found in children's aggression by father's job and mother's age, in children's popularity by school GPA, father's education, mother's education, and fathers job, and in children's isolation by father's age, father's education, mother's education, and father's job. Second, children's aggression was significantly dependent upon self-esteem, loneliness, family harmony, and family communication. Children's popularity was related with school grade, name satisfaction, body satisfaction, self-esteem, number of close friends, loneliness, family harmony family communication, parental love and acceptance, and perceived closeness to mother. Children's isolation was significantly associated with school grade, body satisfaction, self-esteem, number of close friends, loneliness, family harmony, family communication, parental love and acceptance, and perceived closeness to mother Third, according to the multiple regression analyses, it was found that highly aggressive children tend to report less family harmony, more loneliness, and a larger number of friends. Also, highly popular children tend to report less loneliness, larger number of friends, strong family harmony, and higher academic achievement. On the other hand, highly isolated children tend to perceive weak family harmony, more loneliness, and lower body satisfaction. Lastly, the overall peer status indicator depended significantly on family harmony, loneliness, self-esteem, academic achievement, body satisfaction.

Seismic isolation technology has a wide application to protect bridges from earthquake damage, a new designed bridge pier with seismic isolation are provided for railways in seismic regions of China. The pier with rocking isolation is a self-centering system under small and moderate earthquakes, and the unbonded prestressed tendons are used to prevent overturning under strong earthquakes. A numerical model based on pseudo-static testing results is presented to evaluate the seismic performance of isolation bridge piers, and is validated by the shaking table test. It is found that the rocking response and the loss of prestressing for the bridge pier increase with the increase of earthquake intensity. Besides, the intensity and spectral characteristics of input ground motion have great influence on displacement of the top and bottom of the bridge pier, while have less influence on the bending moment of the pier bottom. Experimental and numerical results show that the rocking-isolated piers presented in this study have good seismic performance, and it provides an alternative way for the railway bridge in the regions with high occurrence of earthquakes. Therefore, we provide the detailed procedures for seismic design of the rocking-isolated bridge pier, and a case study of the seismic isolation design with rocking piers is carried out to popularize the seismic isolation methods.

Objective : The present study examined the effectiveness of the mindful self-compassion (MSC) program on anxiety, depression, self-compassion and emotion regulation. Methods : A total of 29 subjects (mean age 27.5±6.5 years, 15 males and 14 females) participated in a standardized 8-week MSC program. The control group consisted of age- and sex-matched twenty participants (mean age 26.0±2.9 years, 11 males and 9 females). All subjects completed self-report measurements at two weeks before and after the MSC program. Results : MSC training improved self-compassion as demonstrated by the significant group x time interaction effects on the total Self-Compassion Scale scores (F[1, 47]=8.324, p<0.01). Regarding the subscale scores, a significant improvement in self-kindness, isolation and mindfulness components of self-compassion was observed after MSC training. A significant group x time interaction was observed on the self-kindness subscale (F[1, 47]=4.664, p<0.05), with a significant main effect of time (F[1, 47]=23.723, p<0.001). The isolation subscale showed a significant group x time interaction (F[1, 47]=8.698, p<0.001). For the mindfulness subscale, there was a significant group x time interaction (F[1, 47]=6.611, p<0.05) and main effect of time (F[1, 47]=6.611, p<0.05). MSC training also improved the acceptance emotion regulation strategy, as demonstrated by the significant group x time interaction in the acceptance subscale scores of the Cognitive Emotion Regulation Questionnaire (F[1, 47]=6.845, p<0.05). Conclusion : MSC training showed efficacy in fostering self-compassion and improving emotion regulation. Thus, this program might be applicable to improve mental health.
