Background: A school-based smoke free home (SFH) program is useful in empowering the mother and child to reduce secondhand smoke exposure but the effects of pretesting on knowledge and attitude has been largely ignored. We aimed to test whether such a program can be effective in Southern Thailand with an additional assessment of the net effect of the pretest. Materials and Methods: A Solomon four-group design was used. Twelve rural primary schools were assigned to one of the four conditions (each with 3 schools): intervention with and without a pretest, control with and without the same pretest. The intervention was performed in the classroom and home over a period of 1 month. Outcomes were assessed at baseline and 3 months after the intervention on whether the home was smoke free and related knowledge and attitude. Results: The intervention could lead to a smoke-free home without statistical significance. Attitude, knowledge and self-confidence on creating a smoke-free home, and self-confidence in avoidance of secondhand smoke exposure and persuading smokers to not smoke in their home were significantly improved. No pretest effect was observed. Conclusions: Gain in attitude, knowledge and self-confidence among family members from the brief school-based education should be enhanced by other measures.

The purpose of this study was to determine the effect of nutrition instruction using a curriculum guide on nutrition knowledge attitudes and food behaviors of students in a junior high school home economics course. We used three instruments co collect data: a nutrition knowledge test, a food and attitude instrument containing four scales, and a two-part food behavior assessment form A quasi-Solomon four -groups experimental design was used One experimental group was pretested taught nutrition via the curriculum, and posttested A Second experimental group which was not pretested was taught nutrition via the curriculum and posttested One control group was pretested and posttested and a second control group was only posttested Neither control group receive food and nutrition instruction until after the study was complete The results indicate that the experimental group had significantly improved knowledge scores and improved attitude scores on the scale entitled Eating New Foods Nutriton Affects Health Caring about Nutrition Significant changes were observe in posttest scores on the food behavior assessment form Key findings useful in understanding the impact of education on adolescent food choices were that 1) study participants nutrition knowledge improved 2) their attitudes toward nutrition became more positive 3) their intention to include more high-nutrient foods in their diet increased significantly.

Early life exposure to aflatoxin B1 (AFB1) and low protein diet through complementary foods during weaning is common in parts of Africa and Asia. This study evaluated the effect of co-exposure to AFB1 and low protein diet on the extrahepatic tissues of rats. Twenty-four three-week old weanling male albino rats were used for this study and were randomly assigned into four groups: group 1 served as control and was fed normal protein diet (20% protein), group 2 was fed low protein diet (5% protein), group 3 was fed normal protein diet + 40 ppb AFB1 while group 4 received low protein diet + 40 ppb AFB1, all for eight weeks. Afterward, biomarkers of anemia (packed cell volume (PCV), hemoglobin) and kidney function (urea, uric acid, and creatinine) were determined in the blood while biomarkers of oxidative stress were determined in the tissues spectrophotometrically. Co-exposure to AFB1 and low protein diet significantly (p < 0.05) decreased body weight gain and PCV, increased biomarkers of kidney functions and induced oxidative stress in the tissues studied. There was significant (p < 0.05) reduction in glutathione concentration while TBARS was significantly increased in the tissues. Co-exposure to AFB1 and low protein diet had additive effects on decreasing the weight gain and potentiation effect of kidney dysfunction in the rats. The co-exposure also decreased antioxidant enzymes and increased oxidant status in the tissues. Our results demonstrate that this co-exposure has deleterious health effects on extrahepatic tissues and should be a public health concern especially in developing countries where AFB1 contamination is common.

Currently, climate change is regarded as one of the most important environmental issues in the 21st century. However, climate change education is not seriously carried out in schools. This study is concerned about enhancing students' recognition about climate change and actions responding to climate change through an history discipline. More specifically, this study tried to identify the effect of history lessons on environmental education, especially focused on climate change, by performing an experiment. The experiment was designed based on Solomon four-group design and carried out in one high school in Gwangmyeong city. Findings of the experiment are as follows. First, students who had taken the reorganized history lesson based on climate change - that is, students with experimental treatments - gained higher understanding of climate change than before and students of control groups. Second, students with experimental treatments gained higher understanding about relationship between history and climate change. Third, students with experimental treatments showed higher possibility of taking responding actions to climate change. In conclusion, history lessons reorganized with environmental issues, for instance climate change, have big potential for environmental education since they contribute to enhancing environmental recognition and prompting responding actions through exploration the effects of existing historical facts. Interdisciplinary approach like that taken in this study will provide students with more comprehensive and extended prism for the environment.

The purpose of this study is to analyze the effects of a comparative process so that students majoring in urban planning and design can develop the ability to present non-physical alternatives along with the ability to present alternatives to a physical environment to solve urban problems. A total of 30 students majoring in urban planning and urban design were analyzed for their satisfaction with their majors, intention to find a job related to their majors, and academic achievement. This was done after conducting a comparative course of living-lab projects utilizing idle space in a region in connection with a major education course for about a year. For the analysis, the four-group design used by Solomon was used to find the differences between students who participated in the class and those who did not. The analysis showed that the students who participated in the comparative course of the living-lab project were highly satisfied with their major and their intention to find a job related to their major. The results of this study suggest that the process of cultivating the ability to work with local residents and merchants to present physical and non-physical alternatives to solve local problems by utilizing the means of living lab projects has a positive effect on the students' attachment to their majors and their self-esteem.

This study examines the problems of children exposed to family violence. As a result, the children exposed to family violence exhibit various emotional, behavioral and social problems and distorted perceptions and inappropriate reactions toward family violence. Based on these results and existing programs for children exposed family violence, an integrative group program has been devised. The program was applied to two groups of the children and an experimental study was conducted to examine its effectiveness on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. As a result, the experimental groups have shown an overall significant improvement in scores on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. The study offers the following recommendations for clinical social work practice. First, great efforts to alleviating the problems of children exposed to family violence should be made continually. Second, special attention should be paid to reflect the characteristics of our own culture in clinical social work intervention and to do so, various practical intervention skills suitable to our culture should be developed. Finally, many different intervention models for children exposed family violence should be developed and researches comparing those models should be carried out.
