Recent epidemiologic studies show that gestational exposure to air pollution adversely affects pregnancy outcomes including low birth weight in preform birth. In this study, we evaluated the effect of air pollutants on LBW (low birth weight) on firstborn fetus throughout the gestational period using the birth cohort between 1999 and 2003 in Seoul. Using birth cohort data from the National Statistics Office of Korea we identified 288,346 firstborn births (excluded missing data on lack of information for birth weight and discordance between residential and certificated address from a total of 316,451) during 1999 to 2003 with complete covariate (gender, parity, date of birth, gestational age, parental age and educational level, maternal occupation etc.) and maternal residential history data. Our subjects were defined as more than 37 weeks and less than 44 weeks of completed gestation and we identified 5,457 persons (1.89%) by low birth weight (<2.5 kg) in this study. Using logistic regression, we estimated the risk of mean (entire pregnancy and trimester period) air pollution concentrations for CO, $O_3,\;PM_{10},\;NO_2\;and\;SO_2$. In terms of trimester-specific exposure, we found that some air pollutants exposure in each trimester would increase the risk for LBW. Results also showed that the effect size of air pollutants exposure during the first and third trimester is higher than during the second trimester. In all trimester, the estimated risk of LBW was 1.831 (95% CI=1.573-2.132) with unit increase for CO, 1.139 (95% CI=1.107-1.172) for 50, and 1.009 (95% CI=1.001-1.017) for $O_3$. Our results suggest that exposure during the gestation period to relatively low levels of some air pollutants may be associated with a reduction in birth weight on first-born fetus. These findings implicate the effective risk management strategies should be applied to minimize the public health impacts for pregnant women.

The purpose of this study was to suggest measures for improving training cooperation between industries and universities through employer engagement by analyzing the state of employer engagement in training. The current study investigated the state of employer engagement in training and factors that facilitate employer engagement in training. A survey was conducted with 230 human resource managers who worked for companies with more than 300 employees. The study results showed that employers perceived their engagement in training for their employees are consumers rather than strategic partners to plan educational service and make decisions in their communities. However, employers perceived that their engagement in training would be effective because their training engagement can result in positive direct and indirect business outcomes. Moreover, the implementation of training programs based on industry needs was revealed as a critical factor for promoting collaboration between industries and universities and leading to employer engagement. Based on the study results, several suggestions are presented for improving training cooperation between industries and universities through employer engagement.

This study was an exploratory study for the development of a competency-based social welfare curriculum. This study was conducted through a literature review focused on guidelines for social welfare published by the KCSWE (Korean Council for Social Welfare Education). The purpose of this study was to explore social welfare professional competencies, subject goals, teaching methods, and the participatory learning environment for the development of a competency-based social welfare curriculum. The findings are as follows. First, each university had been researching professional competencies individually. Second, the social welfare subjects tended to include all elements of knowledge, skills, and attitudes, and these goals were matched with professional competencies set by each university. Third, the guidelines for social welfare subjects provided various teaching methods to achieve the goals of the subject as well as a participatory learning environment based on discussion. However, it was difficult to determine whether the various teaching methods were effective in achieving core and professional competencies. Therefore, it is necessary for KCSWE to set up a standardized competency-based curriculum and research professional competencies based on social welfare, a curriculum and subjects according to their competencies, effective teaching methods, and a method for evaluating educational outcomes.

This study was conducted to analyze the subjective perception types of college students majoring in cooking by applying flip-learning teaching and learning methods to the subject of cooking practice to improve the educational efficiency of cooking-related classes. Also, in order to study subjective perception of small students, we tried to grasp the common structure in subjective attitude and perception using Q methodology, and the analysis resulted in four types. Type 1 (N=5): Problem solving ability effect, Type 2 (N=6): Self-directed learning effect, Type 3 (N=3): Mutual cooperation practice effect, Type 4 (N=6) ): Theory learning effect was analyzed for each unique feature type. Flip-learning is applied to cooking practice classes, which is a learner-centered education that leaves the traditional teaching method. Interest was found to have a very positive effect on learners' opinion sharing and learning outcomes. However, it was revealed that all students need to find additional solutions to problems such as the operation plan for flipped learning and the free ride evaluation method in group learning.

This study suggested a process of redesigning and implementing problem based learning to enhance students' active and collaborative learning activities and learning outcomes. The results of this study are as follows. First, the ef ect of class participation, academic self-regulated learning, and academic self-efficacy were examined. As a result, first, the average of learning activity, class extension, and participation in class was high in the difference between before and after class. Second, the post average scores of all the factors except the 'evaluation' were higher than before. Third, academic self-efficacy showed a significant difference only in 'task preference'. Finally, students' satisfaction with the class was also high. The professor was also able to grasp the characteristics of individual students by designing and operating the classes using PBL, and it was confirmed that the interaction with students increased. Based on the results of this study, we discussed the limitations and educational implications of the problem based learning class and propose successful problem based learning design and operation of the classroom.

The purpose of this study is to suggest a pedagogic direction of home economics education that can form body image which organize self-concept of adolescents positively. To achieve this purpose, the study suggested a body image formation model of adolescents that can be applied to home economics education, and based on this formation model, analyzed contents on body image of current 12 textbooks of home economics education. The main results of this study are summarized as follows: First, to analyze textbook through body image formation model of adolescents, educational contents about body image were categorized into 4 constructs with 8 sub-categories. Second, we found the current textbooks about the child and family life field, food and dietary life field, and clothing life, are handling topics regarding body image formation model of adolescents, such as concepts and components of body image and antecedents and outcomes of body image. We conclude that although the current textbooks handles contents on body image of adolescents, those contents are sporadically presented across the three fields without an integrated perspective. Home Economics, as an entity of educating adolescents' self-esteem through daily life activities, needs to have a topic-oriented approach in developing a curriculum.

The purpose of the study was to examine cooperative education between industry and school recognized by tentatively called managers of cooperative education, teachers in charge of cooperative education between industry and school, in vocational high school in Incheon Area. In order to accomplish the study purpose, the study conducted a research through questionnaire and examined their recognition for cooperative education between industry and school focusing on curriculum (purpose and content), operational system including supporting system (establishment and operational level) and educational type (process, effectiveness, problems and reinforcing measures). The study conducted a survey using Likert 5 score scale and analyzed the survey results using technical statistics such as frequency, average, standard deviation, etc. From the comprehensive results from the survey, it was found that although outcomes from industry-school cooperation are relatively high, participation is insufficient and intermediating organizations connecting concerned parties and mediating them are not enough because recognition and will of interested parties of industry-school cooperation are not sufficient. In addition, policies, legal and systematical and financial infrastructure for activation and efficiency of industry-school cooperation are not established perfectly, therefore, there are a lot of things to be improvement in operation. In particular, it was observed that establishment of internal organization and infrastructure for the number of workers in vocational training organizations are decisively inadequate.

Objectives The number of marriage immigrant women has been increasing in the past several years in Korea and their adaptations to the new environment have been an important social issue. The aims of this study were to evaluate the psychosocial and mental health statuses of Vietnamese marriage immigrant women (VMIW). We intended to compare the mental health of VMIW with married Vietnamese women living in Vietnam and reveal the demographic or psychosocial factors affecting their mental health. Method Subjects comprised one-hundred-forty-three VMIW who enrolled in multiculture family support centers in Chungbuk Province and forty-eight women from Vinh Phuc province in Vietnam. Marital satisfaction, domestic violence and social support were evaluated as psychosocial factors, and the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and General Health Questionnaire (GHQ) were used to evaluate mental health. Results VMIW had a larger age gap with their husbands but better psychosocial statuses. BDI (p = 0.20), BAI (p = 0.08), GHQ (p = 0.13) scores of VMIW were not significantly different compared to Vietnamese residents. Marriage duration of VMIW affects significantly their marital satisfaction, social support and depressive levels (p < 0.01). The level of domestic violence showed a significant difference according to the educational levels of their husbands, composition of family members and marriage process (p < 0.05). VMIW with older husbands and jobless VMIW had low levels of anxiety (p < 0.01). Conclusion The results suggest that VMIW have no difference in mental health compared to Vietnamese women living in Vietnam which is contrary to general expectations. However, various environmental factors, such as marriage duration, have an effect on the mental health of VMIW. As marriage duration is proven to be important factor on mental health of VMIW, more extended duration of care and interventions are needed to maintain good mental health. Networking system connecting mental health screenings by the multiculture family support center to the local mental healthcare center is needed to care those with poor screening outcomes.

We are at the onset of a major revolution in education, a revolution unparalleled since the invention of the printing press. The computer will be the instrument of this revolution. Computers and computer application are everywhere these days. Everyone can't avoid the influence of the computer in today's world. The computer is no longer a magical, unfamiliar tool that is used only by researchers or scholars or scientists. The computer helps us do our jobs and even routine tasks more effectively and efficiently. More importantly, it gives us power never before available to solve complex problems. Mathematics instruction in secondary schools is frequently perceived to be more a amendable to the use of computers than are other areas of the school curriculum. This is based on the perception of mathematics as a subject with clearly defined objectives and outcomes that can be reliably measured by devices readily at hand or easily constructed by teachers or researchers. Because of this reason, the first large-scale computerized curriculum projects were in mathematics, and the first educational computer games were mathematics games. And now, the entire mathematics curriculum appears to be the first of the traditional school curriculum areas to be undergoing substantial trasformation because of computers. Recently, many research-Institutes of our country are going to study on computers in orders to use it in mathematics education, but the study is still start ing-step. In order to keep abreast of this trend necessity, and to enhance mathematics teaching/learning which is instructed lecture-based teaching/learning at the present time, this study aims to develop/present practical method of computer-using. This is devided into three methods. 1. Programming teaching/learning method This part is presented the following five types which can teach/learn the mathematical concepts and principle through concise program. (Type 1) Complete a program. (Type 2) Know the given program's content and predict the output. (Type 3) Write a program of the given flow-chart and solve the problem. (Type 4) Make an inference from an error message, find errors and correct them. (Type 5) Investigate complex mathematical fact through program and annotate a program. 2. Problem-solving teaching/learning method solving This part is illustrated how a computer can be used as a tool to help students solve realistic mathematical problems while simultaneously reinforcing their understanding of problem-solving processes. Here, four different problems are presented. For each problem, a four-stage problem-solving model of polya is given: Problem statement, Problem analysis, Computer program, and Looking back/Looking ahead. 3. CAI program teaching/learning method This part is developed/presented courseware of sine theorem section (Mathematics I for high school) in order to avail individualized learning or interactive learning with teacher.
