Austenitic stainless steel has been widely used because of its good corrosion resistance and mechanical properties. However, intergranular corrosion can occur if the alloy is welded or aged. The objective of this study was to determine intergranular corrosion behaviors of austenitic medium carbon (0.05 wt%) and low carbon (0.02 wt%) stainless steel aged at several conditions. Alloys were evaluated according to ASTM A262 Practice A, ISO 12732 DL-EPR (double loop-electrochemical potentiokinetic reactivation) test, and ASTM A262 Practice C. The degree of sensitization and intergranular corrosion rate were obtained. The relationship between the degree of sensitization and the intergranular corrosion rate showed a very large fluctuation. Such behavior might be related to whether two-dimension tests or three-dimension tests were performed. On the other hand, regardless of carbon content of alloys, when the intergranular corrosion rate increased, the degree of sensitization also increased. However, the DL-EPR test showed a higher sensitivity than the Huey test for differentiating the intergranular corrosion property at a low intergranular corrosion rate, while the Huey test had a higher sensitivity than the DL-EPR test for distinguishing the intergranular corrosion property at a high intergranular corrosion rate.

The purpose of this study was to investigate the degree of family support for diabetic patients and the diet therapy practice of patients themselves, and to analyze the relationship between family support and diet therapy practice and blood glucose control, and thus to prepare basic data for the development of effective education programs to improve blood glucose control in diabetic patients. The study subjects were 82 patients with type II diabetes, aged over 20 in the Chungbuk area. The gender distribution of subjects was 52.4% males and 47.6% females, and BMI showed 29.3% overweight and 35.3% obesity. Among the 82 study subjects, the relationship between diet therapy related family support and blood glucose control was examined in 67 subjects who answered practicing diet therapy, and the results showed that the family support score of a group with excellent blood glucose control was significantly higher than those of groups with fair or poor control (p<0.001) and the correlation between the two factors was very high (r=0.341, p<0.001). For the relationship between diet therapy practice by patients themselves and blood glucose control, diet therapy practice of a group with excellent blood glucose control was significantly higher than those of other groups (fair or poor control groups) (p<0.001) and the correlation between two factors was very high (r=0.304, p<0.001). For other factors influencing blood glucose control, a group with diabetes education showed significantly better blood glucose control compared to other groups without education (p<0.05). From the above results, diet therapy practice by patients, family support, and the necessity of diabetes education were confirmed to control blood glucose of diabetic patients. In conclusion, development and operation of education program should include not only patients but also their family members.

Objective: This study was conducted to assess the current status of experiential education, by analyzing pharmacy students' satisfaction and evaluation for practice sites and preceptors for 3 years from 2014 through 2016. Methods: Students evaluated the practice sites and preceptors using a 5-point and a 4-point Likert scale, respectively. Analysis was performed based on the types of curriculums and practice sites. In addition, sub-analysis was conducted based on the types of health-system pharmacy and the community pharmacy. Results: Total 203 students responded to the survey questionnaires. The 3-year average score of students' satisfaction with practice sites was 4.25. In the sub-analysis conducted based on the types of health-system pharmacy, the score was higher in the tertiary hospital pharmacies than that of the general hospital pharmacies (4.49 vs. 4.06, P<0.001). For community pharmacy, the difference in the score of the 3-year analysis was not significant, depending on the types (4.51 vs. 4.33, P=0.054). The average score of students' evaluation on the preceptors was 3.37 in the 3-year analysis. The score was significantly higher for the preceptors of tertiary hospital pharmacies than those of general hospital pharmacies (3.61 vs. 3.25, P<0.001). For community pharmacy, no significant differences were found, depending on the types of pharmacy (3.53 vs. 3.43, P=0.309). Conclusion: The students' satisfaction with practice sites and preceptors in pharmacy experiential education was high. However, it varied greatly depending on the types of educational institutions. Mutual effort between university and educational institutions is required, to narrow the gap in the degree of students' satisfaction.

Purpose: This study aimed to identify the degree of accident prevention behavior, self-esteem, self-regulation ability, and social support among middle-school students, and investigate factors influencing their practice of accident prevention behaviors. Methods: The participants were 174 students from two middle schools located in J city. Data were collected from December 28, 2017 to February 9, 2018 using self-reported questionnaires. Results: The mean score were $3.08{\pm}0.37$ of 4 for practice of accident prevention behaviors, $3.07{\pm}0.57$ of 4 for self-esteem, $3.69{\pm}0.48$ of 5 for self-regulation ability, and $3.38{\m}0.75$ of 5 for social support. Positive correlations were found among self-regulation ability, self-esteem, social support, and practice of accident prevention behaviors. The factors influencing the practice of accident prevention behaviors were personality (being 'haste') (${\beta}=-.20$, p=.003), self-regulation ability (${\beta}=.48$, p<.001), and social support (${\beta}=.23$, p<.001). These factors explained 39.0% of the variance in practice of accident prevention behaviors. Conclusion: It was found that the middle-school students engaged in prevention behavior to an extent that was insufficient to prevent accidents. Therefore, it is necessary to develop intervention strategies to improve the practice of accident prevention behavior among middle-school students, considering self-regulation ability, social support, and personality, which affect the practice of accident prevention behaviors.

The purpose of this study was to provide the basic data needed to plan the effective teaching design of scaling education and to measure the changes in students' confidence in performing scaling according to the number of scaling practices. Scaling education is presented as a core basic hygiene competency of dental hygienists and evaluated as the practical competency of dental hygienists. This study selected 48 third-year students from the department of dental hygiene at S University in Asan, and analyzed data from completed participant surveys. The degree of "confidence in facing the subject in clinical practice," "confidence in applying hand instrument to the subject," and "confidence in applying ultrasonic instruments to the subject" was assessed on a five-point Likert scale. The difference in confidence was analyzed during five practice sessions. Each response was compared using frequency analysis, chi-square test, and repeated measurement ANOVA. Students who complained of a lack of confidence in the 14.6%, 25.0%, and 12.5%, respectively, in face-to-face practice, hand instruments, and ultrasonic instrument application responses. The more the practice was repeated, the more confident students were in all three categories, and the more statistically significant (p<0.001). As the number of scaling practice sessions increased, students' confidence in performing scaling also improved. In particular, the level of self-confidence was higher after the third practice session when compared to the first session. Therefore, it is necessary to design effective courses for teaching scaling practices so that at least three repetitive practice periods can be provided in clinical dental hygiene practices.
