The concept of bariatric surgery, which was intended to lose weight, has turned into metabolic surgery. These changes were due to the fact that the resolution of diabetes and metabolic diseases after weight loss surgery were not associated with weight loss. The key pathogenesis of type 2 diabetes is explained by increased insulin resistance and reduced insulin secretion. Therefore, postoperative resolution of diabetes can be explained by improvement of insulin secretion or insulin resistance. It is known that the improvement of insulin secretion after surgery depends on the degree of preservation of preoperative beta cell function. In this study, the method of measuring insulin resistance is concretely summarized, and the improvement of diabetes after metabolic obesity surgery is focused on the improvement of insulin resistance.

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.

Purpose: The purpose of this study was to identify the effects of self-differentiation, psychological discomfort, and dyadic adjustment on maternal-fetal attachment in primigravidae. Methods: In total, 108 primigravidae participated in this correlational study. The participants answered self-report questionnaires. Data were collected from January 14, 2020 to May 4, 2020, and were analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression with SPSS for Windows ver. 23.0. Results: The mean age of the primigravidae was 31.66 years. The mean score for the degree of maternal-fetal attachment was 76.81 out of 96 points. Participants’ scores for maternal-fetal attachment differed significantly based on age (t=2.08 p=.039) and marital status (t=2.05, p=.043). Maternal-fetal attachment was significantly negatively correlated with psychological discomfort (r=–.39, p<.001), and significantly positively correlated with self-differentiation (r=.36, p<.001) and dyadic adjustment (r=.36, p<.001). Self-differentiation explained 24.1% of variance in participants’ maternal-fetal attachment, and its effect was statistically significant (F=7.79, p<.001). Conclusion In primigravidae, more self-differentiation was associated with stronger maternal-fetal attachment. To strengthen maternal-fetal attachment in primigravidae, it is necessary to develop an educational program that increases their level of self-differentiation and minimizes their psychological discomfort. Additionally, it is recommended to provide nursing interventions to encourage couples to work together throughout the gestational period.

Purpose: The purpose of this study was to develop a child abuse prevention education program for parents. Furthermore, the aim was to investigate the impact of child abuse prevention education on parents’ response to positive emotion, parenting stress, and potential for child abuse. Methods: A randomized controlled pretest posttest design was used. A total of 60 participants, who were parents with children aged 1~5 and attending 8 nurseries and kindergartens located in Daegu, were recruited. They were randomly assigned to an experimental group (n=30) and a control group (n=30). The collected data were analyzed by an independent t-test, paired t-test, and χ²-test along with descriptive statistics using IBM SPSS Statistics 25.0. Child abuse prevention education for the experimental group included four modules on child rights, understanding child abuse, proper child discipline, and positive parenting attitudes. Results: The experimental group showed a significant difference in positive rumination from the control group (t=2.15, p=.036). The experimental group reported a significant difference in dampening from the control group (t=-2.49, p=.016). Additionally, the experimental group reported a significant difference in parenting stress from the control group (t=-2.12, p=.038) and also reported significant differences in child abuse potential from the control group (t=-2.26, p=.028). Conclusion The results of this study indicate that child abuse prevention education for parents can improve positive rumination, reduce dampening, and reduce parenting stress and child abuse potential. Therefore, this study is useful in demonstrating how parental susceptibility to child abuse can be decreased. Future studies should pursue long-term programs and counseling programs.
