This study investigates longitudinal patterns in middle school students' mathematics interest and achievement using panel data from the 4th to 6th year of the Gyeonggi Education Panel Study. Results from the multivariate growth mixture model confirmed the existence of heterogeneous characteristics in the longitudinal trajectory of students' mathematics interest and achievement. Students were classified into four latent classes: a low-level class with weak interest and achievement, a high-level class with strong interest and achievement, a middlelevel-increasing class where interest and achievement rise with grade, and a middle-level-decreasing class where interest and achievement decline with grade. Each class exhibited distinct patterns in the change of interest and achievement. Moreover, an examination of the correlation between intercepts and slopes in the multivariate growth mixture model reveals a positive association between interest and achievement with respect to their initial values and growth rates. We further explore predictive variables influencing latent class assignment. The results indicated that students' educational ambition and time spent on private education positively affect mathematics interest and achievement, and the influence of prior learning varies based on its intensity. The perceived instruction method significantly impacts latent class assignment: teacher-centered instruction increases the likelihood of belonging to higher-level classes, while learner-centered instruction increases the likelihood of belonging to lower-level classes. This study has significant implications as it presents a new method for analyzing the longitudinal patterns of students' characteristics in mathematics education through the application of the multivariate growth mixture model.

Purpose: The purpose of this study was to explore the nurses' perception of the importance of evaluating continuing nursing education programs. Methods: Subjects were 465 nurses enrolled in continuing nursing education programs at five university hospitals in Seoul and Gyeonggi-do. Data were collected from September 20, 2011 to October 13, 2011. The instrument was developed by the author through a literature review. Content validity was established from a panel of six experts. Data were analyzed using SPSS/WIN 18.0 program. Results: The purpose of the program was rated as the most important domain by the subjects. Interestingly, 'program outcome' and 'effectiveness of program' were ranked below the mean (M=$3.64{\pm}0.75$). These two domains were influenced by the district of work and the type of institution. The position of the participants at their institutions made the significant differences on their perception of 'program purpose.' Conclusion: The results of this study might aid us to have better understanding for what nurses perceive the importance of evaluating continuing nursing education programs. This information might be able to be used for improving programs. Further studies are needed to explore the validity of the instruments to evaluate continuing nursing education programs.

Using the 1st to 5th wave data from Gyeonggi Education Panel Study(GEPS), this study analyzed the change of school effectiveness of middle schools by innovation school expansion in Gyeonggi province. For this purpose, the analysis employed difference-in-difference model with repeated cross-sectional data and the dependent variable was comprised of academic achievement, school satisfaction, creativity, and sense of community. Results showed that the effectiveness of innovation schools had not significantly different from general schools before innovation school expansion but significantly improved in academic achievement and school satisfaction compared to general schools after the policy applied. On the other hand, the school effectiveness in creativity and sense of community not significantly different between innovation and general schools in both before and after. As time passes, the effectiveness of existing innovation schools in the academic achievement was improved and the school satisfaction was maintained. In addition, the effectiveness in satisfaction of the schools was improved as general schools with high effectiveness in academic achievement were transformed into innovation schools. Based on the results, the policy for innovation school expansion was evaluated and the issues related to this policy were discussed.

This study purposed to analyze how teacher experience of instructional change (EIC), teacher morale (TM), and school climate (SC) mediate or moderate the relationship between teacher efforts on instructional improvement (EII) and teacher efficacy (TE). For the purpose, the 6th year data of Gyeonggi Education Panel Study (GEPS) which was administered in 2017 for the 9th grade students and their teachers from 197 middle schools in Gyeonggi Province was used. As results, the mediation effects of EIC on the link between EII and TE was found only under the innovative climate. The moderation effects of TM on the connection between EIC and TE were appeared in both of the permissive and the innovative climate. Finally, the moderated mediation effects of the TM in the innovative climate were bigger rather than in the permissive climate.

This study was to explore epistemological features presented in texts of exhibit panels in the science museum located in Gyeonggi Province. Out-of-school or daily experiences allow more properly and potentially students to form informative science image, because the understandings of scientific epistemology were constructed tacitly through various experiences over a long period of time. The target for this study was panel texts of exhibits in a science museum as an of out-of-school context. The analytical framework was adopted from epistemological frameworks by Ryder et al. (1999). The research results were explored in the categories of relationship between scientific knowledge claims and the data, the nature of lines of scientific enquiry, and social dimension of science. It revealed that one exhibit might reflect the characteristics of one epistemological position: relating one data to one knowledge claim; generating knowledge claim from scientists' individual interests or from discipline's internal epistemology; scientists working as a community or an institution. Findings suggested that the exhibits of a science museum including panel texts and medium need to reflect the wide ranges of scientific epistemology.

An inverse correlation between obesity and arterial stiffness has been reported, but there are no consistent results in elderly subjects. This study examined the relationship between the arterial stiffness measured by the CAVI (cardio-ankle vascular index) and BMI (body mass index) in healthy elderly people. This study included 629 healthy elderly people aged 65 and over who underwent health examinations at a general hospital in Gyeonggi from July 2018 to June 2019. Metabolic syndrome was diagnosed using the criteria of the Adult Treatment Panel (ATP) III of the US National Cholesterol Education Program (NCEP). Among the criteria of NCEP-ATP III, the waist circumference and obesity criteria were based on the WHO criteria. All subjects underwent a biochemical blood test and an assessment of the CAVI. In both men and women, the CAVI was lower in the obese group than in the normal weight group. Gender (P=0.047), age (P<0.001), BMI (P<0.001), and waist circumference (P=0.008) were factors affecting the CAVI. Gender, high blood pressure, and hyperglycemia were independent positive predictors of the CAVI levels, while obesity was a negative predictor. Therefore, the CAVI and BMI showed an inverse correlation. In conclusion, there was an inverse correlation between the CAVI and BMI in the elderly, and obesity was a negative predictor of the CAVI.

The purposes of the study were to identify knowledge and skill levels required for effective nutrition teachers and to compare perceived need and dietitians' self-evaluation of the knowledge and skills. A total of 60 knowledge statements and 70 skill statements associated with 11 job functional areas were specified through a literature review and expert panel reviews. A total of 457 dietitians working at school foodservices in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire and 148 responses were returned. Excluding responses with significant missing data, 142 responses were used for data analysis. In terms of knowledge, 'sanitation, food safety and employee safety(4.60)' category received the highest perceived need score, followed by 'nutrition education(4.56)' and 'nutrition counseling(4.45).' The knowledge category that received the highest self-evaluation was 'nutrition and menu management(3.66)' while the category that received the lowest self-evaluation was 'teaching practices(2.83).' In terms of skills, the highest perceived need was associated with 'nutrition education(4.49)', followed by 'sanitation, food safety and employee safety(4.46)' and 'nutrition counseling(4.39).' The dietitians rated their skills related to 'sanitation, food safety and employee safety(3.67)' the highest but their skills related to 'teaching practices(2.84)' the lowest. The dietitians' self-evaluated knowledge and skill scores were significantly lower than their perceived need of the knowledge and skills in all job functional areas(p<0.001). A quadratic analysis based on the requirement and self-evaluation of the knowledge and skills revealed that priorities of the education programs targeting school nutrition teachers or students preparing to be a nutrition teacher should be placed on improving knowledge and skills related to nutrition education, nutrition counseling, teaching practices, sanitation and employee safety, and nutrition and menu management. Educational programs for nutrition teachers should be designed to decrease the gaps between the need and self-evaluation of the knowledge and skills for effective nutrition teachers. The findings of the study can be used to develop education materials for nutrition teachers. The knowledge and skills identified in the study should be updated and revised regularly to reflect changes in regulations and current practices in school foodservice programs.

This study investigated the influence of life satisfaction, accomplishment value, peer attachment, and relationship with teachers on the self-esteem of adolescents in three time points. The study population consisted of a nationally representative sample of middle school 1st grade students who completed the Korean Children and Youth Panel Survey(KCYPS) of the National Youth Policy Institute in 2010, 2012, and 2014. Descriptive statistics used included frequency, percentage, average, and standard deviation; in addition, reliability, repeated measure ANOVA, and regression results were reported using SPSS statistics. The results were as follows. First, this study showed that the longitudinal changes of self-esteem, life satisfaction, accomplishment value, peer attachment, and relationship with teachers were significantly different across three time points. Second, longitudinal changes in adolescents' self-esteem, life satisfaction, peer attachment, and relationship with teachers differed by gender, but accomplishment value did not. Third, life satisfaction was the most influential to self-esteem and peer attachment was the second most influential in the three data sets after controlling for gender, parents' academic attainment, and residential area. The influence of life satisfaction on self-esteem decreased across the three time points, but that of peer attachment increased over time. Instruction on life satisfaction and peer attachment needs to be more highlighted in Home Economics classes to enhance the self-esteem of adolescents.

This study investigated the impact of social capital on married immigrant women's parenting, specifically focusing on the mediating effect of parenting participation. Using structural equation modeling, social capital within and outside of the family were examined in their relations to parenting efficacy, and the mediating effect of parenting participation was analysed. Study participants were 459 immigrant women from the Gyeonggi Education Welfare Panel(2011), who had children in 5th and 6th grades of elementary school. Findings suggested that social capital within and outside of the family had significant impact on parenting participation, which in turn affected parenting efficacy. Direct effects of social capital on parenting efficacy were not statistically significant, indicating a full mediation effect of parenting participation. Implications for social work practice and social policy for this population are discussed.

This study examined the effect of bilingual bicultural home environment and mother's command of Korean language on their participation in child rearing as well as on children's developmental outcomes. We carried out Analysis of Covariance Structure using the 1st year(2011) data of Gyeonggi Education Welfare Panel, which consists of 459 matched pairs of immigrant women and their 5th~6th grade children living in Gyeonggi-do. The results indicated that when the immigrant mother has good command of Korean language and the children are exposed to their maternal culture and language, mothers tend to actively participate in child rearing and this in turn has positive effects on developmental outcomes of their children. These results demonstrate that Korean language programs targeting immigrant women by marriage are important not only for assisting their employment and adaptation but also for enhancing parenting behaviors in multicultural families. Moreover these findings suggest that we need to understand the bilingual bicultural home environment in these families as a significant resource that contribute to their children's developmental outcomes and not as a risk factor to their adaptation, as it has frequently been viewed.
