The purpose of this research is to find out teachers' understanding and recognition about the water and the water environment education and to suggest the strategies of water education at school based on survey results. Results of the study are as follows: First, teachers had high level of water related knowledge and awareness about importance of the water environment education. However, they showed low level of environment educational efforts and environment protection behaviour in daily life. Second, they had a little chance to have the educational training for the water environment education. Third, the water environment education at schools has been made in very restricted areas such as water related scientific knowledge and water pollution. Fourth, teachers pointed out the biggest obstacle for the water environment education would be the lack of teaching materials and the second biggest one was the lack of educational facilities at schools. Based on the survey results, it was found out that in order to improve the water environment education at schools, substantial research by the teachers shall be implemented for all teachers of every subject to build up their capacity in adapting the water education to their subjects.

Objectives: We describe the development of a smoking and drinking prevention program for adolescents, using intervention mapping. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was applied for the needs assessment. We carried out a social diagnosis by assessing the factors such as the quality of life, happiness level, and satisfaction with school life; an epidemiological diagnosis on the perceived health status, stress levels, and priority of health issues; a behavioral diagnosis on the smoking and drinking rate and the intention to smoke and drink; and an educational diagnosis on knowledge, beliefs, attitudes, self-efficacy, outcome expectations, social norms and life skills. Results: The development process included a needs assessment, identifying factors that influence smoking and drinking among adolescents. Intention, knowledge, perceived norms, perceived benefit, perceived cost, perceived susceptibility, self-efficacy, and life skills were identified as determinants. Three performance objectives were formulated to describe what an individual needs to do in order to avoid smoking and drinking. Subsequently, we constructed an intervention matrix by crossing the performance objectives with the selected determinants. Each cell describes the learning objectives of the smoking and drinking prevention program. The program used methods from the transtheoretical model, such as consciousness raising, outcome expectations, self-reevaluation, self-liberation, counterconditioning, environmental reevaluation, and stimulus control. The program deals with the effects of smoking and drinking, self-improvement, decision making, understanding advertisements, communication skills, social relationships, and assertiveness. Conclusions: By using the process of intervention mapping, the program developer was able to ensure a systematical incorporation of empirical and new data and theories to guide the intervention design. Programs targeting other health-related behavior and other methods or strategies can also be developed using this intervention mapping process.

This study investigated school mathematics curriculum of England, newly revised in 1998, focused on the 'shape, space, and measures' domain among three major domains of the English curriculum. On the basis of its understanding, this domain was compared and analyzed with school mathematics curriculum of Korea. In doing so, this study explored its plans and procedures and established a frame of comparison for the curriculums between the two countries. The structure of the National Curriculum in England is composed of programmes of study and attainment targets. The former sets out what should be taught in mathematics at key stages 1, 2, 3, and 4 and provides the basis for planning schemes of work, and the latter sets out the knowledge, skills, and understanding that pupils of different abilities and matures are expected to have by the end of each key stage. Attainment targets are composed of eight levels and an additional level of increasing difficulty. According to the results of the present study, Korea focuses on the formal and systematic mathematical knowledge on the basis of sound understanding of certain mathematical terms or concepts. On the other hand, England curriculum tends to deal with the content which can be understood more intuitively, flexibly, and naturally through the experience and aquisition based on the concrete manipulation. Particularly, it emphasizes that mathematics be realistic and useful in solving a diverse problems confronted in everyday life.

This study sought to evaluate DNA damage and repair in porcine postovulatory aged oocytes. The DNA damage response, which was assessed by H2A.X expression, increased in porcine aged oocytes over time. However, the aged oocytes exhibited a significant decrease in the expression of RAD51, which reflects the DNA damage repair capacity. Further experiments suggested that the DNA repair ability was suppressed by the downregulation of genes involved in the homologous recombination (HR) and nonhomologous end-joining (NHEJ) pathways. The expression levels of the cell cycle checkpoint genes, CHEK1 and CHEK2, were upregulated in porcine aged oocytes in response to induced DNA damage. Immunofluorescence results revealed that the expression level of H3K79me2 was significantly lower in porcine aged oocytes than in control oocytes. In addition, embryo quality was significantly reduced in aged oocytes, as assessed by measuring the cell proliferation capacity. Our results provide evidence that DNA damage is increased and the DNA repair ability is suppressed in porcine aged oocytes. These findings increase our understanding of the events that occur during postovulatory oocyte aging.

The purpose of this study was to provide basic materials and assistance for developing a nutritional education program targeting marriage immigrant women, and it was carried out on 86 female marriage immigrants living in the Gyeongbuk region. An average age of the female marriage immigrants who participated in this survey were 28.6 years, and their home countries were the Philippines (32.6%), Vietnam (29.1%), and so on. Exactly 59.3% of subjects had been married for 1~5 years, and 40.7% of the subjects had an education status of less than middle school graduation. The majority of them (65.1%) had one more children, and 51.2% of subjects were a part of a nuclear-family, with the husband's age between 40~49 years old (58.1%). Concern for nutrition label was significantly different according to number of children (P<0.01), period of marriage (P<0.001), and education level (P<0.05). It was demonstrated that a higher level of education was associated with a higher need to learn about nutritional information. Understanding nutritional facts and knowledge was significantly higher among the women with two children than no child (P<0.05), period of marriage >10 years than <1 year (P<0.01), and education level of college & university graduation than less than middle school (P<0.05). Sixty percent of the women surveyed participated in the education program of 'Korean language' as they were in their country, and the most preferred education program was 'Korean dietary life and culture' (39.5%). Regarding participation and educational method, the majority of subjects responded that they wanted to learn nutritional education in a cooking academy or school (52.9%) and public health center (34.1%).

The purpose of this study was to investigate the relationship between wive's sex-role attitude and their marital satisfaction for understanding a part of marital relations. For this purpose, a questionnaire was constructed and administrated to 626 married women. the sex role attitude scale was a modified version of the sex-role attitude scale constructed by Osmond and Martin, and the marital satisfaction scale was developed basing upon the scales used by Terman and Hayes & Stinnett. The result of this study are summarized as follows; The majority of wives have relatively modem attitude toward their sex role in the extra familial roles. Wives have relatively modem attitude toward their sex role when the couples are younger, more educated, on a higher income level and working or a job (especially or a professional job). Wife's education level, husband's education level and family income make significant difference in their marital satisfaction specifically, a wife would be relatively more satisfied when she has more education and the family income level is higher. It is founded that wives sex role attitude has significant relationship with their marital satisfaction. A wife tends to be more satisfied when she has a traditional sex role attitude . A professional wife who has a traditional attitude shows most satisfaction and one who has a modern attitude and not having a job tends to be most dissatisfied with her marriage. It is also founded that a wife who has traditional attitude and received college education are above shows most satisfaction while the wife who has modern attitude and received high school education or below shows most dissatisfaction with their marriage lives.

Purpose: This study was done to evaluate the formal education program provided by the Korean government for care workers for frail elderly people. Methods: This study was a cross-sectional survey in which 438 certified care workers who had completed the education program participated. Data were collected from June to October 2009, using a self-report questionnaire consisting of satisfaction with, and understanding of the education program. Results: The participants had a mean age of 46.7 yr, 87.9% were female and 58.2% were high school graduates. For the theory part of the education, the highest score for understanding was for 'supporting household & activities of daily living' while the lowest score for understanding was for 'care for death and dying'. For the practical education, the highest score for understanding was for 'talking with the client' and the lowest score was for 'first aid & basic life support'. There was a significant difference in satisfaction and understanding of the theoretical and practical parts according to educational level. Conclusion: Continuing education programs are needed for care workers for elders, both in the theoretical and practical areas. Also the content of programs should address the weak points of this formal education program.

This study was conducted to investigate the changes of dietary attitudes and behaviors in relation to the use of computers of elementary school children in Seoul. The total of 451 elementary school children, consisting of 235 females and 216 males, participated in the study. The result of domestic characteristics, dietary attitudes and behaviors, the level of the use of computers, and health-related symptoms of the subjects were achieved through the questionnaires as follows: The average height, weight, BMI and obesity-index of the participants were 149.0 cm, 42.4 kg, 19.0, -8.6, respectively. Anions subjects, 42.8％ answered their bed times were between 11~12 pm, and 82.4％ answered that they had extracurricular activities. The most desired activity as their leisure was computer works (female: 44.3％, male: 62.5％). 38.4％ of children used the computers for 1~2 hours a day and the most general usage of computers was a computer game (66.1％). The changes in dietary habits of the subjects were such as eating faster(30.2％), having lots of snacks(28.8％), eating anything at hand(26.4％), skipping breakfast due to over-sleeping(18.4％). As changes in life patterns, those in the time managements for watching T.V.(35.3％), reading(35.0％), exercising(31.9％), sleeping(27.5％), relaxing(27.5％) and other hobbies(26.4％) were observed. In conclusion, many children were being affected by the socioeconomic factors changing the environments, especially by the need for the use of computers. The rates of eating alone and skipping breakfast were getting higher in the dietary patterns of elementary school children. We found that the changes in social environments according to the heavy use of the computer were affecting on their dietary pattern. The direction and method of nutrition education had to be established for the proper understanding of the desirable dietary behaviors.

To approach science education for all which has been required in STS program, it is indispensable to develop variously differentiated education courses that are suitable for various students. In order to do that, we have to abstract essential items that are dealt with in common from science textbook which is regarded as the kernel of science education. Then, these items are developed by fitting for each level-STS science study models. The purpose of this study is to improve the level-based investigation competence by applying these models to various level learning. We obtained some results as the following: First, there has been a positive change for attitude to study science in part. Second, we find the materials in our life and this study is relating to science, technique and society. So we find out the fact that there is close connection between science technique and our life. And also it helps encourage to learn. Third, in the process of searching for and producing STS materials, students have a chance to study for themselves by working out self-leading research activity. Finally, students can reduce a preconception that science is difficult by encouraging attitudes to search for and make our problems in our life scientifically and the habits thinking of and understanding our daily life itself in the scientific sight.
