Purpose: The purpose of this study was to investigate the effects and characteristics of health care programs for pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: This study was conducted according to the Cochrane Collaboration's systematic literature review handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. We searched eight international and domestic electronic databases for relevant studies. Two reviewers independently selected the studies and extracted data. For each study, information on the research method, participants, characteristics of the program, and results were extracted using a previously established coding table. The National Evidence-based Healthcare Collaborating Agency's risk of bias assessment tool for non-randomized studies was used to assess the risk of bias of the included articles. A qualitative review of the selected studies was performed because the interventions differed considerably and the measured outcomes varied. Results: Out of 128 initially identified papers, seven were included in the final analysis. The risk of bias was evaluated as generally low. Health care programs for pregnant women with GDM showed positive effects on blood glucose control. Anxiety and depression were reduced, and self-management and self-care behavior, self-efficacy, and maternal identity improved. Conclusion: Our study provides clinical evidence for the effectiveness of health care programs for pregnant women with GDM, and its results can be used to support the development of health care programs for GDM. More well-designed research is needed on GDM, especially studies that deal with emotional stress and apply a family-oriented approach.

How to generate the precise broad group cross section is important for the fast reactor design. In this study, a fast reactor multi-group cross-section generation code MGGC2.0 are developed in-house for processing ultrafine group MATXS format library. Validation and verification are performed for MGGC2.0 code by applying the benchmarks of ICSBEP handbook, and the results of MGGC2.0 agree well with that of MCNP. The consistent P_N method with critical buckling search is in good agreement that condensed with TWODANT flux and flux moment for the inner core and outer core region. For the radial blanket and reflector, two region approximation method has been applied in MGGC2.0 by using collision Probability Method neutron flux solver. The RBEC-M benchmark was used to verify the power distribution calculation, and the relative error of power distribution comparison with the reference are less than 0.8% in the fuel region and the maximum relative error is 5.58% in the reflector region. Therefore, the precise broad cross section can be generated by MGGC2.0 for fast reactor.

In previous studies, fire simulation was used to estimate the fire spread path. According to previous studies, the fire spread path was estimated to be the main staircase, but consideration of interior materials and internal bulkheads was insufficient. In this study, the ignition time of the 3rd layer was analyzed using the prediction formula considering the interior materials and internal bulkheads. As a result of referring to the architectural drawings, it was found that the interior material of the 3rd floor was made of polystyrene. The internal ignition time of the third floor using FDTs was calculated to be 14,070 seconds (about 234 minutes). The internal ignition time of the 3rd floor using the Handbook on Design Calculation Methods of Fire Behavior was calculated to be 3,104 seconds (about 51 minutes). As a result of calculating the ignition time through the predictive formula, there is a large difference in the ignition time, so it is necessary to review the condition of the variable as a result of the calculation in the future.

The purpose of this study was to establish food ingestion factors needed to assess exposure to contaminants through food ingestion. The study reclassified the raw data of the Korean National Health and Nutrition Examination Survey in 2001 into 12 subcategories including grain products, meat products, fish and shellfish, and vegetables for international comparability of exposure evaluation. The criteria for food intake calculation were unified according to the characteristics of food groups, and recommended values for food ingestion factors were calculated through moisture correction and recategorization of cooked, processed, and mixed foods for each group. The average intake rate for grain and grain products was 6.25 g/kg-d per capita and the men's intake rate was approximately 8% higher than that of the women. The average intake rate of meat and meat products was 1.62 g/kg-d per capita and the men's intake rate was 30% higher than that of the women, on average. The average intake rate of fish and shellfish was 1.53 g/kg-d per capita, and the age groups of 1 to 2 and 3 to 6 recorded higher capita intake rates than other age groups, 2.62 g/kg-d and 2.25 g/kg-d, respectively. The average intake rate of vegetables was 6.47 g/kg-d per capita, with the age group of 1 to 2 recording the highest per capita intake rate of 9.79 g/kg-d and that of 13 to 19 recording the lowest mean. The study also offers recommended values for food ingestion factors of other food groups by gender, age, and region. The food ingestion exposure factors will need future updates in consideration of ongoing changes in food consumption behavior.

Background: Smoking and smokeless tobacco use are almost always initiated and established during adolescence. More than 80% of adult smokers begin smoking before 18 years of age. The main objective of the present study is to assess the feasibility of preventing adolescent tobacco use with the help of a specially designed tobacco control program. Materials and Methods: A cross sectional survey on tobacco use and related health effects was conducted using a structured questionnaire in 13 randomly selected schools in Kannur district of Kerala. These students were followed for a period of one academic year with multiple spaced interventions such as anti-tobacco awareness classes, formation of anti-tobacco task forces, inter-school competitions, supplying IEC (information, education and communication) materials and providing a handbook on tobacco control for school personnel. Final evaluation was at the end of one year. Results: There were 4,144 school children who participated in the first phase of the study. The prevalence of tobacco smoking and chewing habits were 9.85% and 2.24% respectively. Ninety-one percent had parental advice against tobacco use and only 3.79% expressed desire for future tobacco use. The final evaluation witnessed a sharp decline in the current tobacco use as 4.68%. We observed a statistically significant difference towards the future use of tobacco (p<0.001) and awareness about the ill effects of passive smoking (p<0.001) among boys and girls. Further a significantly increased knowledge was observed among boys compared to girls about tobacco and oral cancer (p=0.046). Conclusions: The comprehensive school based tobacco control project significantly reduced the tobacco use pattern in the target population. School tobacco projects incorporating frequent follow ups and multiple interventions appear more effective than projects with single intervention.

The purpose of this study was focus on development of educational objectives by using oral health education in the elementary school from now on. Based on the results of analysis compared with a model of educational objectives and contents by reflecting the programs for analysis were the oral health education programs of the Ministry of health and social Affairs in Korea, and the programs of two states in u.s. in order to construct goals and contents of oral health education in school. The results in this study can be arranged as follows: First, an analysis on the educational objectives of dental health education program resulted that, from a viewpoint of Bloom's taxonomy of educational objectives, in case of domestic, most learning objectives expressed in the handbook of Ministry of Health and social Welfare were given too much emphasis to the cognitive domain of 37 an items in all. Affective domain were appeared the lack of balance of the development domain. Second, the result of analysis for the programs of two states of America, the cognitive domain were the most abundant of 48 an items in all, and were not significantly different to those of Korea in the form of objectives domain or statement. However a big different was shown that they organized the same objectives domain as a pattern of repeating and deepening at every grade. Third, in this study, 10 educational objectives of dental health education were established, based on the result of analyzing those existing educational programs as central figure. Those are oral cavity, brushing, nutrition of teeth, fluoride, flossing, teeth injury, dental decay, periodontal disease, malocclusion, routine dental visits. And general objectives and specific objectives of each learning area were stated and arranged grade by grade.

Curve number (CN), originally developed, compiled by 'The Natural Resources Conservation Service (NRCS)', and has been widely used throughout the world. However, there is the uncertainty of CN derived from the use of antecedent moisture condition (AMC)/Antecedent Runoff Condition (ARC). As in Korea where nearly 70% covered by mountainous area, it is still not sufficient handbook precedent to guide or support the estimation of AMC/ARC. The failure to develop formal criteria of applying AMC/ ARC will be a gaping profession and results not only in uncertainty of CN estimation in particular, but also in designing appropriate structures in Korea as a whole. This paper is aiming at presenting a critical review of AMC/ARC and deriving a procedure to deal more realistically with event rainfall-runoff over wider variety of initial conditions. Proposed methods have been developed. It is based on modifying estimated runoff to observed runoff with coefficient of determination and then applying different algebraic expression with the verification of AMC by antecedent rainfall table of NEH-1964. The result shows that algebraic expression by Arnold et al. (1996) is the most appropriate for AMC/ARC and the results of AMC/ARC estimation criteria are generally very close to each other. Therefore, this algebraic expression might be applied in South Korea condition properly.
