OBJECTIVES: The purpose of this study was to reveal psychological traits, risk factors, and predictors of the military maladjusted group. In addition, we attempted to compare the correlation of temperament, character profile, and resilience between maladjusted and adjusted groups. METHODS: A total of 166 maladjusted soldiers who joined the green camp of three divisions and 125 adjusted soldiers participated in the survey from July to December 2013. As self-report questionnaire methods, Beck Anxiety Inventory, Beck Depression Inventory (BDI), and the Korean version of the Connor-Davidson Resilience Scale, Temperament and Character Inventory (TCI) were used. T-test, binary logistic regression analysis, Pearson's correlation, and multiple regression analysis were used as analytical methods. RESULTS: The maladjusted group showed a high level of anxiety, depression, and Harm Avoidance and a low level of resilience, Reward Dependence (RD), Persistence, Self-Directedness, and Cooperativeness compared with the adjusted group. BDI and RD were found to be statistically significant for prediction of military maladjustment. Higher correlation between resilience and TCI was observed for the maladjusted group, but not the adjusted group. CONCLUSION: We suggest that a high depression level and a low RD level should be included as predictors among target symptoms for development of psychological treatment for the maladjusted group. In addition, we suggest that the level of resilience can affect correlation of resilience with TCI.

To fine out the changes of DNA ploidy and cellular proliferation activity during carcinogenesis and evaluate correlation between flow cytometrically determined S-phase fraction and proportion of proliferation cell nuclear antigen(PCNA, PC10) immunoreactive cells, the authors studied on malignant fibrous histocytoma induced by intra-articular injection of 9, 10-dimethy1-1, 2-benzanthracene(DMBA) in the rats. Forty Wistar rats were used. The results obtained were as follows. 1) Firstly, tumors were palpated 5 weeks after the last injection of DMBA and formed in 27 rats at sacrificed. Histologically, these lesions showed storiform, indicative of malignant fibrous histiocytoma. 2) Three cases of DNA aneuploidy were observed at 4 and 5 months after the last injection of DBMA and one of them, which was DNA diploidy at main mass, was found at daughter mass. 3) Flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells in malignant fibrous histiocytoma induced by DMBA were much higher than in control groups and slightly increased according to sequential changes after formation of mass. The comparison of flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells showed significant correlation(r=0.6092, p<0.001). Above results strongly suggest that ploidy pattern may evolve into aneuploid type during the development of tumor and proliferation activity increases during the carcinogenesis.

A malignant granular cell tumor (MGCT) occurred in the left shoulder of a 62-year-old man. The patient underwent wide marginal excision followed by chemotherapy and radiotherapy. A metastatic tumor was identified in the axillary lymph node 22 months after the excision of the shoulder mass. The primary tumor was a poorly circumscribed mass measuring 5 5 4 cm. On cut section, it was a solid mass with yellowish tan color. Histologically, both primary and metastatic tumor consisted of polygonal cells with abundant granular cytoplasm and a vesicular nucleus with a prominent nucleolus. Two to three mitotic figures per ten high power fields at 200 were counted. Tumor cells were weakly stained with periodic acid-Schiff (PAS) preparation both before and after diastase digestion, and were positive for S-100 protein, neuron-specific enolase (NSE), and vimentin. By electron microscopy, the cytoplasm was filled with numerous autophagolysosomes containing myelin figures, mitochondria, and fragmented rough endoplasmic reticula. Basal laminae and angulated bodies were also noted. These findings suggest schwannian differentiation of this tumor.

Journal of Korean Neuropsychiatric Association 2022;61(1):28-37
Objectives:
Physicians experience high occupational stress due to heavy workload, responsibility and stressful situations in the medical field. Although occupational stress decreases productivity and increases medical accidents, occupational stress on Korean psychiatrists is not well studied. In this study, we investigated the occupational stress and career satisfaction of Korean psychiatrists.
Methods:
Electronic surveys were conducted via e-mail, and a total of 266 psychiatrists fully answered the surveys. The surveys consisted of the Korean Occupational Stress Scale (KOSS), career satisfaction and stress inventory for the health professional.
Results:
The mean KOSS score of Korean psychiatrists was lower than the score of other Korean professions (43.99 vs. 46.03). There are significant differences in the sub-items of KOSS, depending on the lifestyle, the career and the hospital on duty. Psychiatric residents scored significantly higher in job control and occupational climate than psychiatrists. On the other hand, workplace relationships and job insecurity scored significantly higher in psychiatrists. Psychiatrists working in general and university hospitals had higher stress in job demand than psychiatrists working at private psychiatric hospitals. Job control and lack of reward scores were high in psychiatrists working in national psychiatric hospitals, and 21.8% of psychiatrists answered that they would not become a psychiatrist again.
Conclusion
This study showed the overall job stress level of psychiatrists in Korea, and they were experiencing high job stress in different areas depending on factors, such as position, working environment and living habits.

Recently, a method of fabricating an esthetic anterior fixed prosthesis by integrating data such as three-dimensional facial scan and jaw motion to form a virtual patient with dynamic occlusion has been introduced. This enables smooth communication with patients during the diagnosis process, improves the predictability of esthetic prosthetic treatment, and lowers the possibility of occlusal adjustment. In this case report, a virtual patient with dynamic occlusion was created in which the results of the treatment were simulated, and esthetic maxillary anterior fixed prosthesis was fabricated. With the aid of the virtual patient, the final restorations were satisfactory both in terms of esthetic and function.

Communication between coronary arteries and cardiac chambers or large vessels is unusual type of congenital malformation. Aneurysmal formation of a coronary arteriovenous fistula is even rare. We report a case of 83-year-old women with giant aneurysm of the coronary arteriovenous fistula from the left anterior descending coronary artery treated by percutaneous deployment of embolization coil.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

Recently Our medical systems have been changed to a great extent and mental health systems have evolved as well ; with increased mental disorders, suicide, family violence, and increasing an elderly population. Currently, the general population has become more aware of an importance of mental health, and increasing mental disorders in turn led to massive social burdens. This requires an emergence of new national mental health policy. By establishing the national mental health policy, we, Korean Neuropsychiatric Association, are able to build a reputation that we deserve as a professional group, and provide the mental health promotion of the general population and improve the quality of life of those that are mentally ill.
