The probe vehicle penetration rate is a required parameter in the estimation of entire volume, density, and queue length from probe vehicle data. The previous studies have proposed estimation methods without point detectors, which are based on probability structures for the locations of probe and non-probe vehicles; however, such methods are poorly suited to the case of multi-lane streets. Therefore, this study aimed to estimate the probe vehicle penetration rate at a multi-lane intersection and introduce a probability distribution of the queue length of each lane. Although a gap between estimates and observations was found, the estimates followed the trend of observations; the estimation could be improved by the correction factor hereafter. This study is expected to be used as a basic study for the estimation of entire volume, density, and queue length at multi-lane intersections without point detectors.

The purpose of this study was to examine the influence of other-awareness in multicultural adolescents upon psychosocial adjustment and to figure out the mediating effects of self-regulatory ability in this relationship. To achieve this research objective, a questionnaire survey was conducted targeting 127 middle-school adolescents from multicultural families in Busan city. As a result, the other-awareness in multicultural teenagers had a negative(-) influence upon the self-regulation and the psychosocial adjustment. The self-regulatory ability appeared to have a positive(+) impact on psychosocial adjustment. Also, in consequence of verifying the mediating effects of self-regulation in the relationship between other-awareness and psychosocial adjustment in multicultural adolescents, the self-regulatory ability was shown to have a partial mediating effect. In light of this outcome, diverse programs for self-regulation need to be developed in order to enhance psychosocial adjustment in multicultural adolescents. An institutional support from school and community must be made for raising the positive awareness on multicultural families.

This study sought to examine and revise the 'Multicultural Family Support Act' for domestic multicultural families. To this end, we looked at the Multicultural Family Support Act along with the current status and support policies of multicultural families. First, as in Article 1 of the Act, it proposed to reflect Article 3 of the Article 5(basic ideas) to realize the purpose of the law contributing to 'improvement of quality of life' and 'social integration'. Second, the current law stipulates that support and related policies should be implemented every five years, and by conducting planning and due diligence surveys every three years, it suggested the necessity of consensus on the disagreement between the support policy and the planning period. Third, the government proposed a revision to the mandatory regulation (that is, it should be done) under the provisions set by law. Finally, we proposed a plan to designate 'Multicultural Family Day' or to designate it with other family days. As the globalization of the members of each country, which has been rapidly continuing in the 21st century, it is expected that Korea will be able to welcome them and review the act and institutional devices that can be together more than ever.

The purpose of this study was to investigate the effect of horticulture activity program on self-esteem and school life adaptation of multicultural adolescent. A non-equivalent control group pre-post test design with experimental group (n=39) and control group (n=36) was used. The program was conducted from Jan. 2 to Feb. 28, 2017, and the questionnaire was conducted before and after the program. Collected data was analyzed by SPSS(Ver, 24.0), conducting ${\chi}^2-test$, Fisher's exact test, t-test, paired t-test. There were statistically significant increase in self-esteem(t=2.41, p=.021) and school life adaptation(t=3.85, p=.000) by difference between a pretest and a posttest in the experimental group compared to that in the control group. Therefore, the horticulture activity program for multicultural adolescent have a significant effect for better performance of self-esteem and school life adaptation. Also, It was confirmed that the program used for improving adaptability of multicultural adolescent.

The purpose of this study was to identify trends in nursing research on multicultural family in Korea and suggest the direction for future research. A COSI model was used to guide the search process between the years 2008 and 2016, using the keywords 'cultural diversity', 'women', 'spouses', 'family', 'children' and 'nursing'. Of papers 137, 19 were doctoral dissertations, 10 were master's theses and 108 were from academic journals. Nursing research on internal married immigrant women has been steadily increasing since 2011. True experimental studies began in 2014 and most of the experimental studies were quasi-experimental studies. The research subjects were married immigrant women, and research on children, husband, mother-in-law and couple was very poor. The lack of information on the validity/reliability of the translated instruments were noted. The overall findings of this study suggest that future research should include more well-designed experimental studies. It is necessary to extend the study to husband and mother-in-law living with married immigrant women. Considering the ethnic background of the subject, it is necessary to develop a research tool with well-translated validity and reliability.

This study was to analyze whether volunteer motivation represents a mediated effect in the relationship between social support and multicultural acceptance by university students as a late adolescent. Among the students attending a university located in North Chungcheong Province, 256 participants have experienced volunteer work. Data analysis conducted multiple regression analysis using SPSS and analysis showed that social support of university students affected multicultural acceptance and that volunteer motivation in their relationship between social support and multicultural acceptance was fully mediated. Based on these results, it has revealed a path that the social support of university students affects multicultural acceptance through volunteer motivation. Therefore, in order to gain social support, university students should improve their ability to maintain a positive view of interpersonal relations and to cope with conflicts efficiently. They will also have to strengthen self-directing capacity in order to increase the level of motivation for volunteer participation.

This study is a descriptive survey study intended to analyze the relationship between multicultural acceptability, empathy, and global citizenship of nursing students and identify the factors influencing global citizenship. The data was collected targeting 187 nursing students at universities located in the cities of B, U, and S. The collected data was analyzed using t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression analysis. The results were as follows: global citizenship of nursing students was positively correlated with multicultural acceptability and empathy. Factors influencing the level of global citizenship were empathy, multicultural acceptability, which together explained 40.0% of the total variance in global citizenship. Consequently, this study raises the need for the development and application of steady practical programs and various learning methods for the enhancement of global citizenship, which is required in the fields of nursing education where global competence is considered to be important.

Recently, the number of multicultural families has significantly increased in Korea, and this trend creates a need to understand how successfully students from multicultural families achieve their mathematics learning. To understand and predict the changes in mathematics learning achievement of these students over time, we conducted in this study a latent growth mixture model analysis. The study findings show that the majority (92%) of the students from multicultural families experience a decrease in their mathematics achievement over time as their grade level goes up. It was found, in particular, that female students are likely to have lower initial achievements and rapid decline over time more than male students and that the decline over time was more severe for female students than their male counterparts. The findings of this study convey several implications on the how to support the students from multicultural families. First, the result of this study was different from the outcomes of previous studies that presented the income of the household and the education level of the students' parents as major factors that determine the academic achievement of the students from multicultural families. Furthermore, the study indicates the need for more research to identify variables related to the mathematical achievements of the students from multicultural families and the need to use these research findings to develop public support plans for the students from multicultural families.
