1.Development and Effects of a Resilience Training Program for Nurses.
Journal of Korean Academy of Nursing Administration 2016;22(4):373-383
PURPOSE: This study was conducted to develop a resilience training program for nurses and test its effects. METHODS: A non-equivalent experimental group and a control group pretest-posttest study design was used with 56 participating nurses (28 nurses in the experimental group and 28 nurses in the control group). The resilience training program was provided to participants for 4 weeks from August 12 to September 4, 2013. Each session was scheduled for two hours per week. Participants completed the tools for resilience, positive affect, and perceived stress assessment. Data were analyzed using χ² test, Independent t-test, and 2*2 repeated measures multivariate analyses of variance (MANOVAs) with the SPSS/WIN 21.0 program. RESULTS: Application of the resilience training program significantly helped nurses enhance their resilience and positive affect to workplace adversity, and reduce their perceived stress. There were significant positive differences for these variables in the experimental group compared to the control group. CONCLUSION: The findings indicate that the resilience training program for nurses is effective and can be used as an intervention for a stress management guide for nurses.

2.The Mediation Effect of Frustrated Interpersonal Needs on the Relationship between Non-suicidal Self-harm and Suicidal Ideation among College Students
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2020;29(3):273-283
Purpose:
This study explored the relationship between non-suicidal self-harm and suicidal ideation and examined the mediating role of frustrated interpersonal needs on the relationship between non-suicidal self-harm and suicidal ideation based on the Interpersonal Theory of Suicide.
Methods:
A cross-sectional, descriptive study was conducted with 333 college students in Korea. Subjects completed a packet of self-report questionnaires through an on-line survey. The analyses were conducted with IBM SPSS Statistics 25 using descriptive statistics, independent T-test, one-way ANOVA, and Pearson’s correlation coefficients. Bootstrapping was adopted for significance tests regarding the mediation effect.
Results:
Among the subjects, 156 students (46.8%) had non-suicide self-harm experiences. The levels of suicidal ideation were significantly different by gender. Students with experiences of non-suicidal self-harm reported significantly higher levels of frustrated interpersonal needs and suicidal ideation than those without such experiences. The relationship between non-suicidal self-harm and intensity of suicidal ideation was partially mediated by thwarted belongingness, but not perceived burdensomeness.
Conclusion
Findings of this study suggest the inclusion of effective strategies that can have a positive effect on ameliorating thwarted belongingness in developing suicide prevention programs for college students with experiences of non-suicidal self-harm.

Acute fatty liver of pregnancy (AFLP) is one of the sudden unexpected causes in pregnancy and maternal deaths. It has been considered as a potential fatal disease in pregnancy, but the postmortem findings of AFLP is not well known. Because an unexpected maternal death may lead to a legal dispute, forensic pathologists should be aware of clinical presentations and postmortem findings of AFLP. Therefore, we presented our case and reviewed with literatures.

Although the frequency of composite resin restoration in children is gradually increasing, there are insufficient researches about the rate of composite resin repair in children. The purpose of this study was to evaluate the repair rate of composite resin restorations in the permanent first molar in children under 12 years old. This study retrospectively analyzed 169 children treated with composite resin restoration in the permanent first molar from May 2014 to April 2015.According to the location of the tooth, the repair rate was higher in the mandible than maxilla and in the left than right. In the classification of restoration, the repair rate was the highest in the class II cavity, and the repair rate was the lowest in the restoration of the occlusal surface only. Repair rate in two years was 14.8%, and repair hazard ratio decreased with age. The most common reason of composite resin restoration replacement was the secondary caries (74.1%).Within the limits of study, the repair rate of children was higher than that of adult due to the characteristics of children. Therefore, dentists should understand these characteristics and try to reduce the repair rate of composite resin composite restorations.

Nitrous oxide is medically used as an anesthetic gas and as an additive in whipped cream production. Few cases of death from nitrous oxide intoxication have been reported in Korea. However, fatalities due to inhalation of pure nitrous oxide in an amount enough to cause death have been recently increasing. We report two cases of death related to nitrous oxide abuse with a review of literature focusing on the fact that nitrous oxide abuse can be considered as a possible cause of death if appliances with nitrous oxide contents were found during the investigation, and the autopsy and toxicological findings cannot be attributed to nitrous oxide intoxication.

BACKGROUND: We reviewed a series of 188 resected pulmonary mucinous adenocarcinomas (MAs) to clarify the prognostic significance of lepidic and non-lepidic patterns. METHODS: Non-lepidic patterns were divided into bland, non-distorted acini with uncertain invasiveness (pattern 1), unequivocal invasion into stroma (pattern 2), or invasion into alveolar spaces (pattern 3). RESULTS: The mean proportion of invasive patterns (patterns 2 and 3) was lowest in small (≤ 3 cm) tumors, and gradually increased in intermediate (> 3 cm and ≤ 7 cm) and large (> 7 cm) tumors (8.4%, 34.3%, and 50.1%, respectively). Adjusted T (aT) stage, as determined by the size of invasive patterns, was positively correlated with adverse histologic and clinical features including older age, male sex, and ever smokers. aTis tumors, which were exclusively composed of lepidic pattern (n = 9), or a mixture of lepidic and pattern 1 (n = 40) without any invasive patterns, showed 100% disease- free survival (DFS). The aT1mi tumors, with minimal (≤ 5 mm) invasive patterns (n = 63), showed a 95.2% 5-year DFS, with recurrences (n = 2) limited to tumors greater than 3 cm in total size (n = 23). Both T and aT stage were significantly associated with DFS; however, survival within the separate T-stage subgroups was stratified according to the aT stage, most notably in the intermediatestage subgroups. In multivariate analysis, the size of invasive patterns (p = .020), pleural invasion (p < .001), and vascular invasion (p = .048) were independent predictors of recurrence, whereas total size failed to achieve statistical significance (p = .121). CONCLUSIONS: This study provides a rationale for histologic risk stratification in pulmonary MA based on the extent of invasive growth patterns with refined criteria for invasion.

The purpose of this study was to evaluate the accuracy and precision of the three-dimensional (3D) imaging system of children’s facial soft tissue by comparing linear measurements. The subjects of the study were 15 children between the ages of 7 and 12. Twenty-three landmarks were pointed on the face of each subject and 16 linear measurements were directly obtained 2 times using an electronic caliper. Two sets of 3D facial images were made by the 3D scanner. The same 16 measurements were obtained on each 3D image. In the accuracy test, the total average difference was 0.9 mm. The precision of 3D photogrammetry was almost equivalent to that of direct measurement. Thus, 3D photogrammetry by the 3D scanner in children had sufficient accuracy and precision to be used in clinical setting. However, the 3D imaging system requires the subject’s compliance for exact images. If the clinicians provide specific instructions to children while obtaining 3D images, the 3D device is useful for investigating children’s facial growth and development. Also the device can be a valuable tool for evaluating the results of orthodontic and orthopedic treatments.

PURPOSE: Urinalysis is one of the best methods for early detection of renal disease and recent wide- spread use of mass screening led to increasing prevalence of asymptomatic urinary abnormalities. Usually, primary chronic glomerulonephritis first presents with asymptomatic urinary abnormalities and chronic glomerulonephritis commonly causes end-stage renal disease. However, clinical outcome of asymptomatic urinary abnormalities in adults is not well known. METHODS: Between Jan 1995 to Aug 2009, 333 patients with asymptomatic urinary abnormalities who underwent percutaneous renal biopsy were enrolled. A retrospective study was performed to clarify the prognostic factors and the long-term renal outcome of this disease. RESULTS: According to clinical manifestation, there were 79 (23.7%) of isolated microscopic hematuria, 30 (9.0%) of isolated proteinuria and 224 (67.3%) of mixed hematuria and proteinuria. The patients were significantly younger in case with microscopic hematuria. Group with microscopic hematuria had significantly shorter follow up period (p=0.013). In pathologic diagnosis, IgA nephropathy was most common with 244 patients (73.3%). The proteinuria group and mixed group showed significantly higher rate of progression to chronic renal failure than the microscopic hematuria group (p=0.015). The group that 24-hour proteinuria was more than 0.5 g/day showed significantly higher progression rate to chronic renal failure (p<0.000). Using univariate regression analysis, 3 risk factors for progression to chronic renal failure were identified: age, serum creatinine, 24-hour total urine protein. In multivariate regression analysis, only 24-hour proteinuria was the independent prognostic factor for progression to chronic renal failure. CONCLUSION: IgA nephropathy is the most common cause of asymptomatic urinary abnormalities in adults. The group of proteinuria has higher progression rate to chronic renal failure than other groups. Over 0.5 gm of 24-hour proteinuria is a significant risk factor for progression to chronic renal failure in multivariate regression analysis.

OBJECTIVE: The purpose of this study was to compare psychiatric comorbid disorders and psychological outcomes in children and adolescents with Attention-deficit/hyperactivity disorder (ADHD). METHODS: Subjects were divided into a child group (aged under 12 years) and an adolescent group (aged 12 years and above). All subjects were diagnosed with ADHD based on the DSM IV diagnostic criteria using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Korean Version (K-SADS-PL-K). The K-SADS-PL-K was also used to evaluate those psychiatric disorders comorbid with ADHD. And the Korean version of the Child Behavior Checklist (K-CBCL) was used to examine the subjects' psychological outcomes. RESULTS: The rate of comorbidity in adolescent group was significantly higher than that in the child group. In particular, the adolescent group had a significantly higher ratio of comorbid conduct disorder and mood disorder than the child group. With respect to the predominantly inattentive type and Not Otherwise Specified, the school subscale scores on the K-CBCL for the children were significantly higher than those for the adolescents. CONCLUSION: These results suggest that the psychiatric comorbidity may differ between adolescents and children with ADHD. Therefore when treating adolescents with ADHD, more careful assessment and treatment targeting a range of comorbidities are needed.

PURPOSE: High proliferation rate is a hallmark of cancer. The mitotic index is a useful and simple method for analysis of cell proliferation. However, the practical utility of mitotic index as a predictor of prognosis in patients with hepatocellular carcinoma (HCC) has not been determined. Therefore, we examined mitotic index as a prognostic marker in HCC patients. MATERIALS AND METHODS: We counted the number of mitotic cells in 10 high-power fields of the tumor area on hematoxylin and eosin-stained slides representing 282 surgically resected HCCs. The highest number of mitotic cells was defined as the mitotic index. RESULTS: High mitotic index was observed in 127 of 282 HCCs. High mitotic index showed significant association with younger age, larger tumor size, higher Edmondson grade, microvascular invasion, major portal vein invasion, intrahepatic metastasis, higher American Joint Committee on Cancer (AJCC) T-stage, higher Barcelona Clinic Liver Cancer (BCLC) stage, higher alpha-fetoprotein level, hepatitis B virus etiology, and liver cirrhosis. Patients with high mitotic index had shorter disease-specific survival (DSS) (p < 0.001) and tended to have shorter recurrence-free survival (p=0.112). In subgroup analysis among patients with a larger tumor size, microvascular invasion, intrahepatic metastasis, higher AJCC T-stage, and higher BLCL stage, high mitotic index showed unfavorable influences on DSS (p=0.001, p=0.008, p=0.003, p=0.012, and p < 0.001, respectively). In addition, high mitotic index was an independent predictor of shorter DSS (p=0.004). CONCLUSION: High mitotic index may be a novel predictor of DSS in patients with HCC and may have utility as an auxiliary prognostic factor in HCC.
