The basic technique for total reconstruction of the microtia was established by Tanzer, who utilized autologous rib cartilages for constructing the auricular framework. In order to decrease the number of surgical stages and to achieve maximal convolution, we employed a surgical procedure with simultaneous three layered costal cartilage grafting for the high profiled auricle, concha formation and lobule rotation. However, we performed ear elevation as an additional procedure for some patients who had decreased helical height due to absorption of cartilage framework or postoperative trauma and who had wanted to wear the spectacles or to have more natural appearance of auriculocephalic sulcus. From August 1988 to October 1997 we had performed surgeries for the ear elevation of 58 patients in 177 patients with total ear reconstruction, using various elevation methods; skin graft, local flap, and local with costal cartilage block. When the ear elevation was performed with skin graft, postoperative contraction of the grafted skin was inevitable. In cases with two skin flaps, it was difficult to stabilize and maintain the correct projection of the constructed ear. So we elevated the reconstructed ear by utilizing a costal cartilage block, two skin flaps to cover the posterior region and skin graft. We conclude that the local flap with costal cartilage block is one of the most favorable methods in ear elevation which can maintain the adequate projection and make natural looking auriculocephalic sulcus.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

A 45-year-old male with meningeal neurocysticercosis presented with mesence-phalothalamic syndrome as a variant of lacunar syndrome. Brain magnetic resonance imaging showed bilateral paramedian thalamic and mesencephalic infarction with cystic dilatation of the third ventricle. Cerebrospinal fluid analysis confirmed the diagnosis as it showed active inflammation and positive immunologic reactions to cysticercosis.

Journal of the Korean Neurological Association 1994;12(2):183-187
The effect of MPTP on catecholamine neurons in young (4-6 weeks) and aging (10-12 months) C57BL/6 mice was studied using immunocytochemical techniques. Both groups of mice received 4 repeated dosages of 10mg/kg of MPTP given 12 hours apart. We compared the number of tyrosine hydroxylase (TH)-positive cell bodies using immunocytochemical technique in substantia nigra (SN), ventral tegmental area(VTA) and locus ceruleus (LC) 7 days after the last injection of MPTP. There was a significant decrease in the number of TH-positive cell bodies in the SN of young mice, but not in VTA or LC. In aging mice, there was a significant decrease in the number of TH-positive cell bodies in VTA as well as in SN. It is concluded that aging mice are more sensitive to MPTP and show more widespread damage in the catecholamine neurons than young mice, suggesting that MPTP-treated aging mice provide a more useful model for studing anatomical characteristics of Parkinson's disease than young mice.

PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.

Journal of the Korean Neurological Association 1993;11(2):175-180
The effects of 1-methyl-4-phenyl-1, 2. 3, 6-tetrahydropyridine (MPTP) on behavioral and histochemical changes were investigated in C57BL/6 mice. For immunocytochemis try, one group of mice received a dose of 2X30mg/kg of MPTP given 12hours apart and the other group 30mg/kg/day of MPTP for 7days. Locomotor activit,v was measured during 120minutes after a single injection of 30mg/kg of MPTP. We compared the numbers of tyrosine hydroxylase (TH)-positive cell bodies using immunocytochemical technique in the substantia nigra, ventral tegmental area and locus ceruleus 10 days after the last injection of MPTP. There was a significant decrease in locomotor activity during 100minutes after injection of MPTP and the number of TH-positive cell bodies in the substantia nigra of the mice which received the dose of 30mg/kg/day for 7 days, but not in the ventral tegmental area or the locus ceruleus. But 30mg/kg of MPTP given 12 hours apart failed to produce a significant decrease in the number of TH-positive cell bodies in any three catecholamine nuclei examined. It is concluded that MPTP-treated C57BL/6 mice provide a useful model for studying characteristics of Parkinson's disease and the dose of 30mg/kg/day for 7 days is more effective in the animal model for Parkinson s disease in C57BL/6 mice.

Microform cleft lip is a mild form of incomplete cleft lip, also known as a minimal occult, abortive, forme fruste cleft lip. However, it has no definition and few methods have been reported for its correction. A microform cleft lip is characterized as the incomplete union of the superficial portion of the orbicularis oris muscle. It is more prominent during facial expression than in a resting state. We confined microform cleft lip in our study to the absence of philtral skin change and a contracted position on the top of cupid's bow. During the past 5 years, 17 patients of microform cleft lip were operated on. We corrected the defect of the upper vermilion border and nostril sill with minimal incision, and repaired the underlying lip musculature in superficial discontinuity. Reduction of the widened alar base was performed. Deformed alar cartilage was dissected via rim incision, and suspended in a medial and upper direction with pull-out sutures. The most important thing is precise repair of the superficial portion of the separated orbicularis oris muscle via minimal incision, and it is best to operate after 1-year of age for accurate repair. The results were satisfactory and the parents were also satisfied. The advantages of this procedure are as follows: 1. Less visible, minimal scar on upper lip 2. Simultaneous correction of vermillion notching, deformed cupid's bow and nasal deformity. 3. Eversion of philtral ridge due to tenting effect of horizontal mattress suture 4. Philtral elongation effect by reduction of alar base and Z-plasty of cupid's bow.

Journal of the Korean Neurological Association 1992;10(1):8-13
Polymerase chain reaction (PCR) method is a proced.ure for in vitro enzymatic ampli fication of a specific segment of DNA. PCR method was used to detect any M. tuberculi DNA in the 16 cerebrospinal fluid specimens from 6 patients clinically diagnosed as tuberculous meningitis. We synthesized two oligonucleotide primers derived from the sequence of a gene that codes for the 65-kilodalton antigen of M. tuberculosis. The amplified 165bp genomic DNA of M. tuberculosis was detected in 3 specimens (18.5%) with polyacrylamide gel electrophoresis. A following southem blot analysis confirmed these mycobacterial DNAs and detected another amplified DNA (25%) that was not seen on the polyacrylamide gels. Conventional detection methods such as smear and culture for M. tuberculosis found these specimens to be negative. Now we recommend PCR and combined southem blot analysis as a useful tool for early and rapid diagnosis of tuberulous meningitis.

PURPOSE: This study was conducted to identify job experiences of male hospital nurses. METHODS: Data were collected from 20 male nurses working at general hospitals, through semi-structured in-depth interviews. The interviews were recorded and subsequently transcribed verbatim. Using content analysis, data were coded and categorized. RESULTS: The analyzed domains were motivations for choosing nursing, occupational experiences (3 subdomains), and attitudes toward the future. A total of 85 significant statements were selected from the data and classified into 32 categories. The nurses' motivations for choosing nursing were advantages of employment, their aptitude, scarcity value of men, professionalism and job security, good promotion, stable income, and family influence. In occupational experiences, they were assigned to special fields and dissatisfied with vertical relationship, promotion system, their salary, and gaps in military service time; they had difficulties in adapting to female-dominated groups and encountered gender role stereotype and preconception; they were satisfied with their distinguished performance, but had damaged self-esteem, and were stressed and disappointed in their work. In their attitudes toward the future, they considered their career changes, but tried to make professional and personal advancement. CONCLUSION: These findings have implications for recruiting and retaining male nurses in clinical settings.

Journal of the Korean Neurological Association 1992;10(2):219-223
A strictly right handed patient showed aphasia and left hemiplegia following a deep infarct of the right hemisphere. He had no personal or family history o{ left-handedness. His aphasia was persistent and global in nature without right limb apraxia which was tested by serial Modified Western Aphasia Battery There was a deep subcortical infarc tion of the territoy supplied by the right middle cerebral artery without any lesion or .perfusion defect in the left hemisphere on brain CT and SPECT. The frequency of persistent aphasia in the right hemispheric lesion in dextrals has been known to be very low and there was no reported case in Korea So we report a case of crossed aphasia in a dextral with review of literature.
