We propose a practical privacy-preserving clustering protocol over horizontally partitioned data. We extend the DBSCAN clustering algorithm into a distributed protocol in which data providers mix real data with fake data to provide privacy. Our privacy-preserving clustering protocol is very efficient whereas the previous privacy-preserving protocols in the distributed environments are not practical to be used in real applications. The efficiency of our privacy-preserving clustering protocol over horizontally partitioned data is comparable with those of privacy-preserving clustering protocols in the non-distributed environments.

The purposes of the study were to assess the multicultural competencies and to identify potential barriers toward improving multicultural competencies of food and nutrition majors at the university level. A total of 500 students were surveyed and 457 responses were analyzed for the study. The multicultural competencies, based on a literature review, included food culture knowledge, multicultural attitude, and multicultural skills. Approximately half of the respondents took a food culture class as a college course. The food and nutrition majors showed positive multicultural attitudes; however, food culture knowledge scores for traditional Korean food culture and 11 other food cultures remained low (average score: 63.7 out of 100 points). In addition, familiarity with cultural foods and knowledge of food-related cultures were not necessarily related. As a result of factor analysis, multicultural skills, required for dietitians, were classified into three factors: professional skills, food preparation skills, and communication skills. Overall, students rated their professional skills the highest and communication skills the lowest. Multicultural attitudes and skills increased with school years, and students who took a food culture class showed significantly higher multicultural attitudes and knowledge scores compared to their counterparts. Economical issues, lack of time, and lack of opportunities for learning multicultural competencies in majors and experiencing different cultures were highly rated potential barriers for improving multicultural competencies. Our research indicates that food and nutrition educators should review their curriculums to incorporate content that encourages food and nutrition majors to learn about other food cultures and improve their multicultural competency. These skills will be critical for food and nutrition professionals in the multicultural age.

Darangyi paddy in Namhae Gachon village provides natural beauty with its distinct location. Darangyi is a traditional Korean landscape, shaping a circular form to serve continuous cultivation. Despite the paddy's landscape, it is difficult to preserve its natural scenery due to many factors such as inadequate visual analysis. Under the belief that there is a necessity to preserve Darangyi paddy, the research in visual features of the paddy began to illustrate the relevance between its viewpoint and landscape objects. First, we researched typical view structures. When considering the visual features, Darangyi paddy landscape objects has a viewpoint from the horizontality to its below, which its center area is about $-5^{\circ}{\sim}-30^{\circ}$. From the analyzed data, the scenary of Darangyi paddy, which most people agree its decency, is formed in a visually decent location. The above type of measure of visual structure in Darangyi paddy is expected to be applied in maintenance of foothold of views in the future. Second, the surrounding elements play important parts to form the whole landscape of Gachon Darangyi paddy. Although Darangyi paddy is the principal part of the scenary, the landscape analysis showed a high relevance with the paddy's identity, forest around the paddy, sky, ocean, settlements, and the roads in terms of visual perception. It was affirmed that those elements around the paddy play important parts in structuring and providing the beauty of the whole landscape. Various viewy objects are seen obvious especially in a long distance, and the splendid scenary proved that those viewy objects are in indispensable location. In order to preserve the paddy, it seems necessary to consider the surrounding envrionment of Darangyi paddy, not just the paddy's sole landscape form. Third, Darangyi paddy has a distinct seasonal characteristics. According to the survey analysis, the full heading time in spring and time when people can take a picture against the sun light proved magnificence of Darangyi paddy. Thus, it would be ideal to maintain Darangyi paddy by securing the sunlight condition with decent landscape view and the views from its surrounding environments or researching the ways to principally maintain the surrounding environments.

This study examined the aspects in elementary school students' career interest and career awareness by gender, age, and multi-cultural families/general families. The subjects were 341 elementary school students from multi-cultural families and general families. The results were as follows. First, there were significant differences in investigative, artistic, and social interests by gender. The children from multi-cultural families and general families showed no significant differences in career interest. Second, the children from general families had higher scores than those from multi-cultural families in self-awareness, occupational exploration, career attitude, and career awareness. And the girls had higher scores than boys in self-awareness, occupational exploration, and career awareness. Third, there were meaningful differences in career interest and career awareness by age. The younger children had higher scores in career interest and lower scores in career awareness. Fourth, the career interests had significant correlations with career awareness in both groups. And there were stronger correlations in general children. Fifth, the regression analyses showed that career interests had significant effects on career awareness in both groups, and there were higher effects in general children. The artistic interests in multi-cultural children and the social interest in general children had significant effects on career awareness. And the effect of multi-cultural families/general families was noticeable in occupational exploration, career attitude, and career awareness. The implication for multi-cultural career education and counseling practice are discussed based on the result of the present study.

To increase the acceptance of multicultural youth, it is necessary to grasp the factors influencing multicultural acceptance. This study was conducted to provide basic data for a future study for the promotion of multicultural acceptance of adolescents by systematically analyzing research trends in factors affecting the multicultural acceptance of Korean adolescents. From 2008 to 2017, we searched 6,435 papers combining the keywords 'multicultural,' 'acceptability,' 'teenager,' 'middle school' and 'high school,' and analyzed six articles. The qualitative evaluation refers to Community Guide and STrengthening the Reporting of OBservational studies in Epidemiology(STROBE). The results revealed that factors influencing multicultural acceptance include gender, experience of overseas visits, life satisfaction, parental neglect and abuse, parent education, school and community factors, and community awareness. Multicultural acceptance of adolescents in Korea was influenced not only by specific factors, but also by various factors such as individual, family, school, and community. These factors were also found to change with age. Based on the results of this study, it is necessary to provide an environment and education that promote multicultural acceptance.

The multi-span suspension bridge generally has more than three towers and two main spans. To economically and effectively design a multi-span suspension bridge, the proper stiffness ratio of the center tower to the side tower must be determined. This study was conducted to propose a method of figuring out briefly the structural behavior of the towers in a multi-span suspension bridge. In the equivalent suspension bridge model, the main cable of the multi-span suspension bridge is idealized as an equivalent cable spring, and the external loads of horizontal and vertical forces that were calculated using the tensile forces of the main cable were applied on top of the towers. The equilibrium equations of the equivalent multi-span suspension bridge model were derived and the equations were solved via nonlinear analysis. To verify the proposed method, a sample four-span suspension bridge with a main span length of 3,000 m was analyzed using thefinite element method. The displacements and moment reactions of each tower in the proposed method were compared with the FEM analysis results. Consequently, the results of the analysis of the equivalent suspension bridge model tended to be consistent with the results of the FEM analysis.

The purpose of current study was to examine how the attitudes toward culture and the experiences of cultural exchanges could influence on the multi-cultural awareness in health science college students in South Korea. Convenience sampling was conducted for data collection; thus, total 407 health science college students of ${\bigcirc}{\bigcirc}$ University in K province were recruited and asked to complete the survey for this study. As a result, those who had the experiences of contacting immigrants, had the experiences of contacting immigrants via the school activities, and took the classes related with multi-culturalism showed high multi-cultural awareness. In addition, attitudes toward culture and experiences of cultural exchanges showed positive relationship with a multi-cultural awareness. At last, based on the regression analysis, attitudes toward culture and experiences of cultural exchanges showed significant influences on the multi-cultural awareness in health science college students in South Korea. Health science students could play important role in immigrants' physical and psychological health care in the future. Based on the findings of this study, we strongly suggest to provide proper education and various activities of multi-culturalism to those students. It would lead to a high quality of care and firm health care system for the immigrant population residing South Korea.

The purpose of this study is to analyze mediating effects of sense of community between Ego-identity and multicultural acceptance. Struatural analysis is performed with six - year panel survey data of elementary school 1st grade students and middle school 1st grade students from Korean child- Youth Panel survey. The subjects of six - year panel survey data are the sixth grade in the elementary school and High school seniors. The results are as follows. First of all, there are differences in Ego-identity, sense of community and multicultural acceptance between the sixth grade in the elementary school and high school seniors. Second, they are related. Third, regression analysis shows that Ego-identity and sense of community have an affect on multicultural acceptance. Fourth, partial mediating effect is suitable for whole youth and sixth grader and complect mediation effect is suitable for high school seniors. In early adolescents, Ego-identity plays a direct role in multicultural acceptance. But in late adolescents, sense of community plays a direct role in multicultural acceptance. Base on these results, for improving adolescents multicultural acceptance, It has suggested educational programs that helps to enhance Ego-identity and sense of community.

The present study examined the direct effects of parental support and monitoring on multicultural adolescents' school adjustment and the mediating role of ego-resilience in the relationships, under the condition of controlling foreign mothers' Korean language abilities. We used data from 1,325 1^st grade middle school students from multicultural families, who participated in the Multicultural Adolescent Panel Survey(MAPS) administered by the National Youth Policy Institute(NYPI). Structural equation modeling analysis revealed the following: parental support and monitoring directly and positively related with multicultural adolescents' school adjustment, and the direct effect of parental support on the school adjustment of multicultural adolescents was greater than that of parental monitoring. In addition, the adolescents' ego-resilience partially mediated the relationships between parental support and monitoring, and their school adjustment. Finally, we recommended the roles of parent education and home economics education in supporting school adjustment and elevating ego-resilience in multicultural adolescents.

In this research, the researchers constructed a survey questionnaire for measuring the multicultural competence of Korean mathematics teachers and administered the survey to 309 mathematics teachers. The analysis indicates that Korean mathematics teachers' level of multicultural competence is rather low (the mean is 2.636 and the standard deviation .290). In particular, the mean of the multicultural competence related to mathematics was lower than the mean of the multicultural competence in general. Moreover, there was no significant difference between the groups according to the length of teaching experience, the participation into the course in multicultural teacher education, and the experience of indirect exposure to people of different cultural background. On the contrary, the experience of direct exposure to people of different cultural background and teachers' major led to a significant difference in the within group comparison. Moreover, the analysis showed that mathematics teachers' level of competence in subject matter had significant impact on their teaching practice responsive to students' backgrounds. Based on the results, the researchers presented implications for the development of multicultural mathematics teacher education to enhance mathematics teachers' competence required for their teaching in culturally diverse school.
