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.

The aim of this study was to review previous literature to determine the effects of nature-based program for workers. This systematic review was conducted in accordance with National Evidence-based Healthcare Collaborating Agency's guidance for undertaking systematic reviews for intervention. Literature search was performed using National Assembly Digital Library, Korean Studies Information Service System, and Korea Education & Research Information Service for literature published until March 2019. The participants were full-time workers, and intervention of nature-based programs was conducted in the outdoor, indoor, and indirect nature contact exposures, with comparators in the control group who did not receive the treatment. The results showed that the programs were effective in physical, psychological, and social health. The methodological quality of randomized controlled trials (RCT) was assessed using the Cochrane Risk of Bias(RoB) tool, while non-randomized controlled trials (N-RCT) were assessed using the Cochrane Risk of bias assessment tool for non-randomized studuies (RoBANS). A total of 16 studies were selected for assessment: two RCTs, 10 N-RCTs, and four one-group pretest-posttest designs. Most interventions were provided at the workplace and in the community. There were many kinds of nature-based interventions, and forest therapy and horticultural therapy programs were most common. Various interventions for workers effectively improved job stress, depression, serum cortisol and stress-response. However, the included studies lacked methodological rigor. Future research is needed to evaluate the long-term effectiveness of nature-based programs for workers using rigorous research designs.

Increase in world trade commodities along with climate change entails frequent pest insect invasions from subtropical to temperate zones. Tephritidae is one of two families in fruit flies along with Drosophilidae and consists of more than 5,000 species. Some tephritid flies in genera Anastrepha, Rhagoletis, Ceratitis, and Bactrocera are highly invasive and give serious economic damages on fruits and vegetables in temperate zones. This review focuses mainly on Bactrocera fruit flies, which have been well studied in control techniques to defend their invasion and colonization. Though various control techniques against Bactrocera fruit flies have been developed, less efforts have been paid to establish efficient integrated pest management (IPM) programs. This review introduces current control techniques of fruit flies and some successful IPM programs implemented in subtropical islands. In addition, major fruit flies infesting crops in Korea have been also reviewed in their occurrence and control programs.

The principal objective of this study was to determine the importance of obesity management nutrition programs for obese male workers after performing a 10-week nutrition program and to compare changes in the obesity index, health behavior, meal intake, and blood constituents. The study subjects included 44 individuals, all without chronic disease. After the program, the weight, body mass index (BMI), body fat percentage, and waist-hip ratio (WHR) of the subjects dropped. Dietary life behavior scores increased. In particular, more than 30% increases were detected in self-control of surfeit, control of eating speed, temperance, and regular exercise items. Total caloric intake and average drinking intake dropped. Though insignificant, systolic pressure, total cholesterol, LDL-cholesterol, and sGPT all dropped as compared to the levels measured prior to the program. Fasting blood sucrose, triglyceride, $\gamma$-GTP, and atherogenic index dropped significantly. HDL-cholesterol, though insignificant, increased. As the result of examining correlations between the subjects' health life behavior, caloric intake, and improvement in obesity, we noted a significant correlation between self-control of surfeit and temperance in the health life behavior item, along with significant correlations among total calorie intake, surfeit percentage, and daily average drinking intake. These results demonstrated that nutrition program for obese workers performed at the Community Health Center had the effect of reducing obesity, improving health behavior, and improving clinical levels. Thus, it is advisable that obesity management programs be achieved, linking the center of local societies' health promotion projects, community health centers, and workplaces, and various programs should be developed to maintain and continue changes in workers' behaviors, such that the positive effects of improvement in obesity could be maintained, even after the program.

The purpose of this study is to measure how English immersion classes affect students. This study seeks to answer two questions. First, will the young learners gain an international sense? Second, will the students learn English naturally without having to be sent abroad to an English speaking country? Several kinds of immersion programs have been designed and implemented in Korea. However, many students have felt great stress and mental pressure in the immersion programs. Students find the programs stressful because English must be used at all times. In this paper, two groups of elementary school students are compared: one being the control group and the other being the experimental group, an immersion class. The results show that the mental health problems, sensitivities, and rates of depression in the immersion group are greater than those of the students in the control group. Therefore, the immersion students' overall mental health is substandard. The negative effects of lethargy and depression are made worse when they are placed in English only environments. The results indicate more attention should be focused on respecting and understanding the students' overall mental health when teaching them English.

This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.
