PURPOSE: This study tried to explore factors influencing on job maintenance of the mentally disabled who employed before. The subjects of this study were the mentally disabled who participated in community mental health center and social rehabilitation center, there had experienced a job in the past. METHODS: The number of community centers were 27 places, there were located in different region. The number of participants were 221 persons agreed to this study. Data was analyzed by Mean, SD and logistic regression analyzation using SPSS/WIN 14.0. RESULTS: General character such as age was significant factor. Monthly pay and working a day in the midst of job related factors were significant. Moreover, job rehabilitation program satisfaction rate and social support revealed significant factors. CONCLUSION: On the basis of results, Job rehabilitation programs for job maintenance of the mentally disabled should be development and establish mediate strategies to improve social support to them.

PURPOSE: Bone involvement is known to develop in 40-70Yo of pediatric acute leukemia. We aimed to analyze the clinical course and result of therapy in pediatric acute leukemia with bone involvement. METHODS: Twenty-seven patients diagnosed as pediatric acute leukemia at Dong San Medical Center from Jan. 1996 to Aug. 1998 were evaluated. According to bone X-ray and whole body bone scan, the patients were divided into two groups. RESULTS: Twenty-seven patients were enrolled in this study with 14 patients(52Yo) showing definite bone involvement on simple X-ray or bone scan. Mean age of patients with bone involvement was 5.5 years. Regarding the type of leukemia, 9 patients(64%) were acute lymphocytic leukemia. Ten patients(71%) out of 14 with bone involvement complained of bone pain at the involved bony site. Site of involvement was most frequent in the lower extremity. On simple X-ray, osteolytic lesion was found in 7 patients(50%), diffuse osteopenia in 2 patients(14%) and pathologic fracture in 2 patients(14%). In bone scan, radioactivity was increased in whole cases of patients with bone involvement. Thirteen patients(93%) were completely remitted by chemo-therapy, but, one AML patient died due to induction failure. CONCLUSION: Bone involvement occured in 52% of pediatric acute leukemia. Bone involvement was more frequent in male patients in the lower extremity, and osteolytic lesion was the most frequent finding on simple X-ray. There was no relevence between bone involvement and prognosis. Further study will be needed to evaluate long-term survival and prognosis. (J Korean Pediatr Soc 2000;43:806-813)

The relationships between diet and the occurence of the major diseases of our civilization are of both epidemiological and practical importance to public health problems. Diseases associated with dietary factors rank among the leading causes of illness and death in Korea. Not only for assessment for clinical evaluation, but also for epidemiological concern, we need for rapid and inexpensive methods to assess dietary intake in relating nutrition to health. The validity of a self-administered semi-quantitative food frequency questionnaire was evaluated for a group of 103 men and women aged 26 to 65. Intakes of 8 nutrients computed from the questionnaire were compared with those derived from 3-months diet record. The questionnaire estimates of mean nutrient intake were within about 10% of the mean diet record measurements for nutrients evaluated but iron and vitamin A. The correlation coefficients comparing unadjusted nutrient intakes measured by two methods ranged from 0.27(iron) to 0.57(fat). The correlation coefficients comparing nutrient intakes measured by two methods adjusted for age and sex ranged from 0.26(iron) to 0.50(calories). After adjusted for age and sex or caloric intake, the intakes in iron did not show correlation measured by two methods. A simple and relatively inexpensive questionnaire could be useful information on dietary intake for macronutrients. The modification and revision would be required for assessments of intakes in micronutrients.

BACKGROUND: Reticulocyte counts provide clinically useful informations and the most widely used method for counting reticulocytes is a manual microscopic procedure. Although manual method is inexpensive and relatively simple to perform, it is labor intensive and imprecise. So, more rapid and more reproducible methods are needed. METHODS: Reticulocyte counts on 96 blood samples were performed by conventional manual method, H*3 RTX(TM)(Bayer, U.S.A.), and FACScan(TM)(Beckon Dickinson, U.S.A.). The changes of reticulocyte count after storage of samples and certain time intervals after preparation were also examined. RESULTS: Reticulocyte counts(%) by manual method, H*3 RTX(TM), and FACScanM were 2.05+/-2.16, 1.95+/-2.24 and 2.51+/-1.94, respectively. There was no statistically significant differences between manual counting and H*3 RTX(TM)(P>0.05). However, there were significant differences between H*3 RTX(TM) and FACScan(TM), manual counting and FACScan(TM)(P<0.05). Correlation coefficients of three comparisons were all above 0.920. Statistically not confirmed the reticulocytosis sample showed decreasing tendency of reticuocyte count by H*3 RTX(TM) after storage of the sample and prepared sample and others were relatively stable in H*3 RTX(TM)and FACScan(TM). CONCLUSIONS: The result of the mean difference between H*3 RTX(TM) and manual counting is statistically insignificant. So, the H*3 RTX(TM)can be used interchangeably with manual counting atter consideration of cost-effectiveness.

PURPOSE: PCNA has been widely used because it is highly accurate, relatively simple and safe to administer. Regardless of its high diagnostic rate, PCNA has the difficulty in excluding malignancy in the cases of, negative for malignancy" results in PCNA cytologic reports. So, we analysed PCNA cases to evaluate the clinical outcome of "negative for malignancy" results in PCNA cytologic reports. MATERIALS AND METHODS: PCNA in 170 cases were done between January, 1991 and December, 1993 and the diagnosis was malignancy in 86 cases, specific benign disease in 30 cases, "negative for malignancy" in 45 cases and inadequate sample in 9 cases. We analysed 36 cases among 45 cases of "negative for malignancy" results in cytologic examinations. The final diagnosis was made on the basis of histopathologic examinations, radiologic findings and clinical courses. we compared the final diagnosis to the radiologic diagnosis. RESULTS: Of the 36 cases with initial "negative for malignancy" results, the final diagnosis was benign in 30 cases and malignant in 6 cases(17%). In radiologic diagnosis of the malignancy, "positive predictive value" was 42%, "negative predictive value" was 96%, and accuracy was 78%. CONCLUSION: In the cases of PCNA results of "negative for malignancy", malignancy can not be excluded because 17% of the cases are proved to be malignant. And if malignancy is highly suggested at radiologic examination, the possibility of malignancy is 42%, and so intensive follow-up examination is needed.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.
