This research aims to identify important variables and their effects on diabetes prevention or progression from prediabetes to diabetic complication using system thinking. Based on the existing studies, we have constructed a causal loop diagram explaining dynamics of diabetes and have found 7 important reinforcing loops and 3 balancing loops in the causal loop diagram. The CLD displays an effect of increasing prediabetes early detection and awareness on diabetes prevention. The findings indicate that the projects in Korea for reducing incidence of diabetes and potential risk of complication have focused on variables which are related only on diabetes even though prediabetes has been a critical point on diabetes prevention and management. Thus, it also concludes that the effect of projects focusing only on diabetes have faced limitation to manage diabetes accordingly.

Objective: To investigate the clinical effect of riboflavin sodium phosphate on prevention of radiotherapy related esophagitis (RRE). Methods: This retrospective study involved 55 patients with middle and advanced esophageal cancer who were divided into an experimental group of 28 and a control group of 27 patients. Those in the experimental group were treated with riboflavin sodium phosphate combined with conventional symptomatic treatment during radiotherapy; while patients in control group received the latter alone. The incidence and degree of RRE were compared after radiotherapy. Results: The incidences of RRE in experimental and control group were 53.5% and 81.4%, respectively (p<0.05); the incidence of stages III and IV RRE in the experimental group was 17.8%, while in the control group it was 44.4% (p<0.05). Conclusion: Riboflavin sodium phosphate could significantly prevent RRE and reduce the incidence of stage III and IV disease. These results were worthy of further confirmation by randomized controlled trials.

Purpose: This study aims to establish a theoretical framework for the fall prevention behavior improvement program by verifying the associations between fracture risk, fall risk perception, and fall prevention behaviors in women with osteoporosis. Methods: A survey was conducted in 122 women who were diagnosed as osteoporosis by having T-score of the femur bone density below -2.5 standard deviation from the bone density examination performed in 2 orthopedic clinics located in B metropolitan city between July 2014 and September 2014. The risk of fracture, level of fall risk perception, and fall prevention behaviors were measured. Results: Fall risk perception had a complete mediating effect on the relationship between the fracture risk and fall prevention behaviors in women with osteoporosis. Conclusion: The perception of fall risk is important to enhance fall prevention behaviors in women with osteoporosis, and the development of various education programs to improve awareness of fall risk is needed.

Purpose: This study was to evaluate the effects of smoking prevention education on primary school students. Method: This study used a nonequivalent control group pretest-posttest design. The subjects were 189 6th graders of two primary schools, of them, 97 were assigned to the experimental group and 92 were assigned to the control group. Smoking prevention education was applied in 7 sessions for 40 minutes every week. Survey was conducted before and one week after the smoking prevention education to examine student's knowledge of smoking, attitude, and smoking cessation intention. The data were analyzed by descriptive statistics and $x^2-test$, t-test using the SPSS Win 10.0 program. Results: After the completion of the smoking prevention education, there were significant differences between the experimental group and the control group in smoking knowledge (t=2.651, p=.009), but smoking attitude (t=-.492, p=.623) and smoking cessation intention (t=-.425, p=.671) were not statistically significant between the two groups. Conclusion: The smoking prevention education for primary school students increased their knowledge on smoking but didn't have any significant impact on changing their smoking attitude and smoking cessation intention. Further study on longitudinal effect is recommended and the smoking prevention education should be provided continuously at school.

Purpose: This study was conducted to examine the effect of a fall prevention education on the fall related knowledge and fall prevention behavior of the elderly patients in comprehensive nursing care service wards. Method: A quasi experimental study with control group and experimental group was used. A total 62 elderly patients in comprehensive nursing care service wards were randomly divided into the experimental group(n=30) and the control group(n=32). The data collection period was from August to December, 2017. Data were analyzed with $X^2-test$, paired t-test, independent t-test and Pearson's correlation coefficient by using SPSS 25.0. Results: Experimental group reported higher score in fall related knowledge than the control group(t=-10.28, p<.001). Participants who viewed DVD and received the leaflet education reported higher score than those with routine admission education(t=-6.51, p<.001). The experimental group showed significant improvement in fall related knowledge and fall prevention behavior(r=.21, p=.015). Conclusion: The fall prevention program was effective in improving fall-related knowledge and fall prevention behavior among elderly patients. Since the DVD plus leaflet education was effective in improving prevention behaviors, it might be included in routine orientation on admission for the elderly patient in comprehensive nursing care service wards.

This study analyzed the effect of zoning on the distribution of pressure differentials caused by stack effect and air pressurization in a center core type of 80 story super-tall building. The results showed that maximum pressure difference more than 250 Pa can be generated by stack effect without zoning. Zoning of stairwell only resulted in 10 Pa reduction of maximum pressure difference, however, zoning of both stairwell and EV shaft especially at the same floor revealed 50 % reduction in stack effect. It was also analysed that the minimum required air flow rate occurred when the stairwell temperature reached 50 % of temperature difference between indoor and outdoor.

The PL(Product Liability) Law has been going into effect in Korea since July 2002. Accordingly, a company's responsibility for customers who are damaged by the defect in the product safety has been gradually strict and imposed burden on management. This paper gives suggestions as to PL prevention of manufacturing companies through the case research of PL prevention strategies and the prevention systems of the domestic S-company.
