The authors studied paranoid ideation and obsession, using Derogatis' SCL-90, in the subjects of 2,564 male and 1,252 female college freshmen of Yeungnam University. The authors collected the reports of Self-Rating Paranoid ideation and Obsession Scale during the periods from January to February, 1987, and applied ANOVA and t-test on paranoid ideation and obsession scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: 1. There was not significant difference in the mean averages of total paranoid ideation scores between male and female students: male students scored 4.16±3.09, female students scored 4.16±2.91. 2. High scored items were delusion and suspiciousness. 3. Fifty-nine male students (2.3%) showed high paranoid ideation scores of 12 or higher, while twenty-six female students (2.1%) showed the same scores. 4. There was strong tendency toward higher paranoid ideation scores in the students who were dissatisfied with their home atmosphere, college, department and familiarity of parents and those who had pessimistic view of self in the past, present or future in both group (respectively P<0.001). The male students who believed protestantism showed higher level of paranoid ideation scores (P<0.01). The male students who attended the department of fine art showed higher level of paranoid ideation scores (P<0.05). 5. There was significant difference in the mean averages of total obsession scores between male and female students (P<0.05): male students scored 10.40±5.43, female students scored 10.75±5.02 6. High scored items were perfectionism, indecisiveness, inattention & obsessive thoughts. 7. Thirty-eight male students (1.6%) showed high obsession scores of 25 or higher, while fifteen female students (1.2%) showed the same scores. 8. There was strong tendency toward higher obsession scores in the students who were dissatisfied with their home atmosphere, college, department and familiarity of parents and those who had pessimistic view of self in the past, present, or future in both group (respectively P<0.001). The female students who attended the department of home economic & whose educational fees were paid by her brothers & sister, showed higher level of obsession scores (respectively P<0.01).

BACKGROUND: Polymerase chain reaction(PCR) has brought an oppotunity for rapid detection of Mycobacterium leprae in clinical pecimens for the diagnosis of leprosy. Th DNA segment specific to M. leprae was detectable in a matteir of hours and DNA from one orgnisa appeared positive by PCR. However, the PCR tool has not been evaluated using elinical specimeriis from leprosy patients and controls. OBJECTIVE & METHODS: The primers amplifying 372bp segment of rebetitive sequence of M. leprae DNA were used in PCR. Skin biopsy specimens from 102 leprosy patient, and controls were examined for the presence of M. leprae by PCR and the results were aomared with microscopic and histopathologic findings. RESULTS: 1. As a result, of PCR after DNA preparation of M. leprae, six other mycobacteria, ten other bacteria, and skin from leprosy with five other skin biopsy tissues, 372bp DNA fragment was specifically amplified from M. leprae. 2. Dot blot, hybridization of PCR products showed that the 372bp DNA from skin biopsy specimens were derived from M. leprae. 3. As a result of PCR after DNA preparation of 10-fold diluted M. legrae from mouse footpad, PCR gave a positive result as low as one organism. 4. Of 87 specimens in which acid-fast bacilli were found under microcopic examinations 97% had positive PCR results. 5. Of 97 specimens which hadihistopathologic evidences of leprosy 95% had positive PCR results. 6. Of 15 specimens in which acid-fast bacilli were not found under n!icroscopic examinations 73% had positive PCR results. In three of five cases which had neither histopathologic nor microscopic evidences of leprosy had positive PCR results. CONCLUSION: PCR method amplifying 372bp fragment of repetitive seqi,ence was highly sensitive and specific in detecting M. leprae DNA in skin biopsy specimens, thus may be a useful tool as an additive diagnostic method, espcially for cases where microscopic antihystopathologic findings are not definite.

PURPOSE: This study was done to investigate the mediating effect of nursing professionalism on the relationship between nurse's character and organizational commitment of the nurse. METHODS: The participants in this study were 170 nurses who had over 3 months of work experience in hospitals in 2 regions of South Korea. Data were collected using self-report questionnaires. Data collection period was from December 15, 2018 to January 15, 2019, Data were analyzed using the IBM SPSS/WIN 25.0 program. RESULTS: The significant predictors for organizational commitment of nurses were nursing professionalism (β=.42), total clinical career (β=−.30), monthly income (β=−.27) and clinical career in current hospital (β=−.24). These variables explained 36.0% of the variance in the organizational commitment of nurses. Nursing professionalism was found to have a mediating effect on the relationship between nurses' character and organizational commitment. CONCLUSION: These results highlight the importance of nurses' organizational commitment and can be used as meaningful data for intervention research to promote the character of nurses and nursing professionalism.

The authors studied anxiety-depression using New Anxiety-Depression Scale (NADS) in the subjects of 2,564 male and 1,252 female college freshmen of Yeungnam University. The authors collected the reports of NADS during the periods from January to February 1987, and applied ANOVA and t-test on anxiety depression scores in order to compare them between various psychosocial factors and sexes. The results are as follows: There was significant difference in the mean average of total scores between male and female students: male students scored 33.41±8.76 and female students scored 35.34±9.02 (P<0.001). The anxiety-depression scores relating to the items of sleep disturbance, apprehension, facial flushing and fatigue were relatively scored higher in both groups. One hundred and thirty nine male students (5.4%) showed seriously higher degree of anxiety-depression scores of 50 or more, while eighty eight female students (7.0%) showed the same scores. There was a strong tendency toward higher anxiety-depression scores in the students who were dissatisfied with their home atmosphere, colleges, departments, familiarity of parents and those who had pessimistic views of self image in the past, presents and future in both groups (P<0.001).

PURPOSE: Language disorders are characterized by inadequate acquisition of language comprehension or expression. Language disorder involve the exclusion of etiologic or explanatory factors, such as sttutering, delayed speech and phonological disorders. It is important to rule out etiologic factors because delayed speech is often associated with other organic disorders or causes of secondary problems. There is no statistic analysis of the causes of language disorders in Korea. So, we analysed the causes of language disorders. METHODS: From March, 2001 to August, 2003, we examined 113 children with language disorders who had developmental and language tests in the language therapy center in Chungnam National University Hospital. RESULTS: In 113 children with language disorders, 77% are male and 23% are female. Average age is 51.3 months. The causes of language disorders are mental retardation (42.4%), tongue-tie(12.3%), sttutering(10.6%), developmental language disorders(9.7%), articulation disorders(9.7%), autism(5.3%), cleft lips or cleft palates(4.4%), hearing disorders (2.6%), lack of teaching(2.6%). CONCLUSION: These data demonstrate that mental retardation is the most common cause of language disorders. It is important to pediatricians that early diagnosis and early therapy can prevent developmental or learning disabilities of children with language disorders.

PURPOSE: Lower urinary tract symptoms (LUTS) usually co-exist with erectile dysfunction. Although the mechanisms for this are still unknown, there seems to be a correlation between the two diseases. We evaluated the effect of lower urinary tract symptoms on the erectile function and the frequency of sexual intercourse. MATERIALS AND METHODS: 1,216 patients, who visited our hospital due to LUTS from January 2000 to April 2006, were evaluated for their erectile function with using International Index of Erectile Function-Erectile Function (IIEF-EF) domain score, frequency of sexual intercourse per month during the last 3 months, prostate volume, International Prostate Symptom Score (IPSS) and quality of life (QoL). The patients were divided into five groups according to age: younger than 40, 40-49, 50-59, 60-69 and older than 70. The patients were again divided into three group according to IPSS: mild (0-7), moderate (8-19) and severe (20-35). Multiple regression analysis and two-way ANOVA were used to analyze the data. RESULTS: 772 patients were eligible for the analysis. The mean patient age was 53.6+/-12.6 years, the mean IPSS was 13.8 9.2 and the mean IIEF-EF score was 17.0+/-9.4. Among the age and LUTS parameters, only age and IPSS had significant effect on the erectile function (p<0.01). The IIEF-EF domain score showed significant differences among the each age group and also among the age-adjusted IPSS groups (p<0.01, p=0.023). The frequency of sexual intercourse per month during the last 3 months showed a significant difference among the each age group (p<0.01). CONCLUSIONS: Erectile function declines with the age-adjusted LUTS severity as well as with age. The frequency of sexual intercourse per month during the last 3 months declines with age, but not with the age-adjusted LUTS severity.

Anti-idiotype antibody (anti-id Ab) which recognizes idiotope in the variable region of immunoglobulin (Ig) can regulate Ab production by B cells in vivo and in vitro. Although it has been reported that anti-id Ab can suppress IgM production by lymphocytes or hybridoma cells without suppression of cell proliferation, the regulatory mechanism of anti-id Ab is not completely understood. We studied the effects of anti-id Ab on the production of IgG class anti-DNA Ab by hybridoma cells, on the proliferation of cells, and on the transcription levels of Ig genes. In contrast to suppressive effect of anti-id Ab on the production of IgM previously reported by others, stimulatory effects of anti-id Ab on the production of IgG by hybridoma cells as well as the proliferation of these .cells were observed. However, little effect of anti-id Ab on the transcription levels of Ig genes was observed. These results suggest that anti-id Ab can increase Ab production by stimulation of cell proliferation. Furthermore, these results suggest that the effect of anti-id Ab on the production of Ab may be determined by the difference in class of Ab produced by hybridoma cells following the treatment with anti-id Ab.

PURPOSE: To study the MR findings to predict the site of dural attachment in meningiomas. MATERIALS AND METHODS: We retrospectively reviewed MR findings of 23 patients with surgically confirmed meningiomas and analysed the characteristics of dural attachment site of meningiomas and tumor growing vector against dura. RESULTS: In the 10 cases that tumor had a single dural base, the dural base was tumor bed. in the 2 cases that tumor had more than two dural bases, wider, irregular and thicker enhancing dura was tumor bed. In the 7 of the 11 cases of diffuse dural bases with tumor, we could predict tumor bed considering the degree of compression to the brain parenchyma and the tumor growing vector. CONCLUSIONS: In the case of tumor having more than two surfaces contacting the dura or with narrow attachment site, it is possible to predict the site of dural attachment if we consider the characteristrics of dural attachment site and tumor growing vector against dura.

Bone scan using 99m Tc-MDP is the most accurate and reliable method for the early detection of fracture, andgive the most accurate in formation about the healing process of fractured bone. Recent days, the medicolegalproblem about the injured time is frequently provoked in vertebral fracture patient by trauma. The authorsanalyzed the bone scan of vertebral fracture patients from March to Dec. 1983. The authors obtained results asfollows: 1. The minimum time for a fracture to return to normal on a bone scan was 4 month in cervical spine. 2.It was 12 month in thoracic spine. 3. It was 6 month in lumbar spine. 4. Surrounding soft tissue injury was healedwithin 10 days after trauma in our cases. 5. Focal hot uptake is persisted in case of callus deposition on plainfilm, although very small in amount. 6. Healing time is delayed in case of severely compressed vertebral body,belowed the half than normal height. 7. With bone scan it is possible to differentiate the fresh fracture from oldhealed, impossible by plain film. 8. Healing time is delayed in old age.
