Congenital hemihypertrophy is one of the more unusual and interesting errors of nature found in the human race. The hemihypertrophy was first described by Meckel in 1822, and the first case was recorded by Wagner in 1839. Since that time, over 140 cases have been reported. The purpose of this article is to report an additional case along with review of previous literatures.

To clarify that the psychosocial factors affect the eye strain of the VDT workers, self-reporting questionnaire about eye strain, critical flicker fusion(CFF), and 12-item version of General Health Questionnaire(GHQ) were carried out to 13 female VDT workers who have done the electronic editing and 10 female controls who were nurses in one hospital. The sum of eye symptoms of VDT workers were significantly higher than controls, but CFF of both groups were not different. And the sum of eye symptoms and CFF were not correlated. High stress group(sum of GHQ > 3) shows significantly more eye symptoms than low stress group. This result suggest that the psychosocial factors could affect the eye strain of VDT workers.

This study relates to the problems of organizational performance in the Christian hospitals. In this study, quality of working life (QOWL), which harmonizes individual as well as organizational goals, was used as an indicator of organizational performance from the open systems view. In order to identify the behavioral factors influencing QOWL in hospitals, self-administered questionnaires were distributed to 1,926 employees who were randomly selected from fifteen Christian hospitals from August 1 to August 30, 1986. The following results were obtained: 1) All correlation coefficients between QOWL and behavioral variables were statistically significant even though their magnitude varied according to hospital size. 2) Using factor analysis, 32 variables were parsimoniously grouped into four factors: individual conflicts, group behavior, organizational characteristics and situation, and job characteristics. The proportion of variance explained by these factors ranged from 33.5% to 38.6% according to hospital size. 3) The overall effects of the four factors in the multiple logistic models ranged from 0.85 to 3.12 according to hospital size. Among three hospital models, the model for small hospitals showed the best statistical fit. 4) The most influential factor was organizational characteristics and situation with an odds ratio ranging from 1.99 to 3.02. Again, the odds ratio was the highest for small hospitals. 5) For large hospitals, the two main factor effects were statistically significant: organizational characteristics and situation, and job characteristics. For medium hospitals, all main factor effects except job characteristics were statistically significant. For small hospitals, all main factor effects except group behavior were statistically significant. However, a factor interaction effect was shown only for large hospitals where it was statistically significant. 6) To examine whether the four factors influence financial performance, the four factor scores from the two financial performance groups were compared using Mann-Whitney test. The test results showed that the organizational characteristics and situation factor score was significantly different only for small hospitals.

BACKGROUND: Thyroid Transcription Factor-1(TTF-1) acts as a tissue specific transcription factor in the regulation of lung specific gene expression and as morphogenic protein during lung organogenesis. Currently, there is very little information on the cis-acting sequences and transcription and transcription factors that direct the TTF-1 gene expression. DNAse 1 hypersensitive (DH) sites represent a marker for active or potentially active chromatin and are likely to be especially important in gene regulation, being associated with many DNA sequences that regulate gene expression. It is clear that DH regions correlate with genetic regulatory loci and binding for sequence-specific DNA-binding proteins. METHODS: We have used DH site assays to identify putative distal regulatory elements in H441 lung adenocarcinoma cells, which express the TTF-1 gene and HeLa cells. RESULTS: There are four DH sites 5' of the TTF-1 gene. These sites are located at base pair approximately +150, -450, -800, and -1500 from the start of transcription. CONCLUSION: These data suggest that there may be at least one intragenic site and regulatory region 5' prime to the promotor region.

The purpose of this study was to evaluate the administration period of the prophylactic antibiotic and anti-inflammatory drug used to reduce postoperative infection and edema, as compared with normal tissue healing period after operation. Author selected the 98 patients who had been performed maxillofacial bone fracture surgery, orthognathic surgery, sort tissue surgery, removal of miniplate and screw, and cyst operation, among 159 patients admitted to the department of oral and maxillofacial surgery of the one general hospital in Daegu city, during 6 months from January to June 1996. The results was slightly long administration for antibiotics and anti-inflammatory agents, as compared with physiologic healing process after surgery. Conclusively, the author propose that prophylactic antibiotics administration should be limited within 3 to 7 days after operation, and 3 to 5 days for anti-inflammatory drugs.

Side effects of iohexol myelography are known to largely depend on the leakage amount of cerebrospinal fluid at the puncture site of the dura. To evaluate the relationship between side effect incidence and spinal needle size and to assess the possibility of performing myelography in outpatients, iohexol myelography was performed in 100 patients(58 inpatients and 42 outpatients) using variable sized needles. A questionaire including presence or absence, duration and degree of various side effect was used for evaluation of side effect. The overall side effect included headache (15%), back pain (14%). Dizziness (9%), and nausea(4%), etc. The incidences of side effects were 28.0% in total, and 16.7%, 23.5%, 26.3%, 46.4%, in patients using 25G, 23G, 22G, 21G spinal needles, retrospectively. The difference of side effect incidence was not significant between male and female. In conclusion, the use of fine spinal needles(25-26G) is recommended to decrease the side effect incidences in myelgraphy. Our findings support the use of fine needle myelography as a safe, less side-effect procedure, not only for in patients but also for out patients.

Vasectomy as a male sterilization has become increasingly popular as one of methods of planned parenthood in many countries including Korea. In this presentation the subject of an overview of male sterilization consists of mainly technical aspects of the ordinary vasectomy and vasovasostomy. the principle of vasectomy is same but some many different technics have been reported and utilized. specific differences are found in technics for immobilizing the vas for making the scrotal incision. for treating the cut ends of vasa, and for removing segments of vas Therefore the author discusses some important factors so as to provide complete protection against the passage of sperm without any failure and to improve the chances of later reversibility according to his experiences of over 7000 vasectomies and 200 vasovasostomis. In the part of ordinary vasectomy procedure, various items such as ideal operative level local anesthesia immobilization of the vas skin incision isolation for the vas treatments of the cut ends of vas prevention of hematoma formation disappearance rate of residual sperm immediate sterility technic complication psychological effects and antibodies following vasectomy are reviewed. In the part of vasovasostomy numerous factors such as operative technics splint various factors for the successful operation overall success rates and low pregnancy rates are discussed and compared with the author's series.
