OBJECTIVE: This study was conducted to perform histomorphometric evaluations of the bone surrounding orthodontic miniscrews according to their proximity to the adjacent tooth roots in the posterior mandible of beagle dogs. METHODS: Four male beagle dogs were used for this study. Six orthodontic miniscrews were placed in the interradicular spaces in the posterior mandible of each dog (n = 24). The implanted miniscrews were classified into no loading, immediate loading, and delayed loading groups according to the loading time. At 6 weeks after screw placement, the animals were sacrificed, and tissue blocks including the miniscrews were harvested for histological examinations. After analysis of the histological sections, the miniscrews were categorized into three additional groups according to the root proximity: high root proximity, low root proximity, and safe distance groups. Differences in the bone–implant contact (BIC, %) among the root proximity groups and loading time groups were determined using statistical analyses. RESULTS: No BIC was observed within the bundle bone invaded by the miniscrew threads. Narrowing of the periodontal ligament space was observed in cases where the miniscrew threads touched the bundle bone. BIC (%) was significantly lower in the high root proximity group than in the low root proximity and safe distance groups. However, BIC (%) showed no significant differences among the loading time groups. CONCLUSIONS: Regardless of the loading time, the stability of an orthodontic miniscrew is decreased if it is in contact with the bundle bone as well as the adjacent tooth root.

2.The Relationship between Anger Expression and Self-esteem in Nursing College Students.
Journal of Korean Academy of Community Health Nursing 2012;23(4):451-459
PURPOSE: The purpose of this study was to identify the relationship between anger expression and self-esteem in nursing college students. METHODS: A total of 297 subjects aged between 18 and 28 were selected through convenience sampling. Data were collected from March 2 to 25, 2011 using a self-reporting questionnaire. Collected data were analyzed with SPSS/WIN 15.0. RESULTS: Differences in anger expression according to general characteristics were as follows. There were significant differences in violent attitude depending on gender (t=3.003, p<.01). Violent actions differed significantly depending on year in school (F=3.279, p<.05) and whether there is a dual income families (t=-2.23, p<.05). There were significant differences in self-esteem depending on year in school (F=4.553, p<.01), school record (F=15.18, p<.001) and the economic status of the parents (F=4.878, p<.01). There were positive correlations between violent attitude and violent actions, except between violent actions and self-esteem. 10.3% of the variance in violent actions was explained by violent attitude, self-esteem and school in year and perceived acceptance. CONCLUSION: The findings of this study may be useful in understanding the anger expression of nursing college students and developing more specific programs to improve personality and self-control of the mind.

PURPOSE: This study was to identify the relationship among self-management, economic stability, self-esteem, self-achievement and predictor of the self-achievements in elders. METHODS: A total of 294 subjects aged between 60 and 92 were selected through convenient sampling. Data were collected by self-reported questionnaire from May to June, 2008. Collected data were analysed by the SPSS/WIN 15.0 program. RESULTS: Self-management, economic stability, self-esteem, self-achievement were positively correlated. The most significant predictor of self-achievement in elders were self-management and self-esteem.

5.Factors Influencing Productive Activity and Physical and Psychological Ability in Korean Elders.
Journal of Korean Academy of Community Health Nursing 2010;21(1):128-138
PURPOSE: This study was to identify the relation between productive activity and physical and psychological ability in elders. METHODS: A total of 294 subjects aged between 60 and 92 were selected through convenient sampling. Data were collected with a self-reported questionnaire from May to June, 2008. Collected data were analyzed by SPSS/PC Win. 15.0. RESULTS: Of variance in productive activity, 13.3% was explained by house ownership, number of diseases, and successful aging. Of variance in physical and psychological ability, 25.4% was explained by house ownership, perceived health, number of diseases, and successful aging. The correlation coefficient between productive activity and physical and psychological ability was significant (r=.32, p<.001) CONCLUSION: Findings of this study may be useful in understanding the health status of community-dwelling elders and developing more specific health promotion programs.

Pediatric Emergency Medicine Journal 2020;7(2):120-126
Purpose:
This study was performed to investigate the gender differences in suicide attempts in adolescents.
Methods:
We reviewed the medical records of adolescents (≤ 18 years) who had visited a university hospital emergency department (ED) for suicide attempts from January 2018 through December 2019. General characteristics of the adolescents, details of the attempt, and outcomes were analyzed. The characteristics were age, gender, the Korean Triage and Acuity Scale, previous attempts, and psychiatric history. The details were initial Glasgow Coma Scale, attempt-arrival time, living alone, method, place, and motivation of the attempt, and concurrent use of alcohol. The outcomes included psychiatric consultation, ED length of stay, and ED outcomes.
Results:
A total of 86 adolescents were included. Their age ranged from 13 to 18 years, and girls accounted for 65.1%. The girls had more frequent psychiatric history than boys (66.1% vs. 30.0%; P = 0.001) without a significant difference in previous attempts (55.4% vs. 46.7%; P = 0.442). The most common methods of the attempt in the girls and boys were poisoning and sharp objects (53.3% [16 of the 30 boys] vs. 60.7% [34 of the 56 girls]; P = 0.002), respectively. No differences were found in the other details of the attempt and in the rate of psychiatric consultation. The girls had longer ED length of stay (247.0 minutes vs. 186.5; P = 0.033), a lower rate of discharge against medical advice, and higher rates of hospitalization (discharge against medical advice, 53.6% vs. 76.7%; non-psychiatric, 23.2% vs. 3.3%; psychiatric, 12.5% vs. 0%; P = 0.003).
Conclusion
Girls may make suicide attempts, usually by poisoning, and undergo relevant hospitalization, more often than boys. In contrast, boys usually use sharp objects, with a higher rate of discharge against medical advice and lower rates of the attempt and hospitalization.

A 29-year-old male patient was admitted due to subacute onset of right chest pain. He had no history of trauma, chest surgery or other medical disease. Chest roentgenogram showed an expansile, radiolucent lesion on the posterior segment of right seventh rib. Computed tomogram of the chest also showed lytic expansile mass with septation. He took an en-bloc resection of the involved rib. Pathologically there were multiple cystic spaces, filled with blood and collagenofibrous tissue proliferation and locally areas of new bone formation and giant cells of osteoclastic type, which was compatible with aneurysmal bone cyst. We report a case of aneurysmal bone cyst of the rib with a brief review of literature.
