To obtain the prevalence rate of health related symptoms of white collar workers who were not exposed to hazardous agent and to investigate the relationship between subjective symptoms & health related variables, 11,266 subjects who were employed for government organization & private educational institute in Seoul, Chungnam, Kyungpook area were studied in order to provide basic information for the health management of white collar workers. All th subjects visited hospitals to take biannual health examination provided Medical Insurance Association for the purpose of screening of several important adult disease. Todai Health Index(THI) questionnaire which is modified questionnaire of CMI made by Todai was selected for the questionnaire form of this study. During hospital visit for health examination, Todai Health Index questionnaire of 88 questions were filled up by the subjects themselves and confirmed by medical doctor. Major findings obtained were as follows: 1. The abnormal rate of screening test was 22.7% in male, 8.5% in female, and 19.2% in total subjects. The prevalence rate of disease was 13.2% in male, 4.9% in female & 10.9% in total subjects. 2. The prevalence rate of all diseases increased by age and th prevalence rate of male subjects were higher than female subjects in all age categories except that of the anemic disease. 3. While highest prevalence rate in all subjects was observed in cardiovascular disease(4.8%), the prevalence rate were 3.4% in liver disease, 2.0% in diabetic disease, 1.9% in pulmonary tuberculosis & chest disease, 0.5% in kidney disease and 0.4% anemic disease. Liver disease was more frequent in age group of below 29 years old and age group of 30-39 years old, but in older age groups(40-49 years old, above 50 years), cardiovascular disease was most frequent. 4. The highest mean score of THI symptom category was mental instability and the lowest one was skin & anus symptoms. The most frequent symptom of THI was "think a lot before action" in nervousness symptom category and mean scores of the female subjects in all symptom category were higher that those of male subjects. 5. In symptoms and signs of recent 3 months, the most frequent symptom and sign was "generalized fatigue" and mean score of it was 1.85. Multiple comparison analysis of health related factors revealed that "illness in health status" was the highest score(23.54) in male and sometimes drink & drunken in alcohol intake was th highest score(26.13) in female. 6. In multiple comparison analysis, health related factors such as health status, health management, diet habit, taste character, vegetable intake, coffee & beverage, alcohol intake were found to be associated with th overall THI symptom category in both sex and age and smoking in male, type of job in female were associated THI symptom category. 7. In stepwise multiple regression analysis of mean score of THI symptom category(dependent variable) and health related factors(independent variables), the variables of health health status, taste character and alcohol were contributed to THI symptom category in order and the highest correlation coefficient(r) was 0.4085 in male and 0.397 in female in health status of mental instability. 8. The significant health factors contribution to THI symptoms score in male subjects were, in multiple regression analysis with THI symptom category with dependent variable and health related factors with independent variables, health status, diet habit, alcohol intake, taste character, final diagnosis, coffe & beverage, type of job, age, smoking, health management, meat intake and in female were health status, type of job, diet habit alcohol intake, coffee & beverage consumption, screening test, age, health management. The most significant contribution factor among health related variables was health status in over all THI symptom category.

윤규호,전인성,신용길,박준호,허남오,방석준 大韓顎顔面成形再建外科學會 1996 Maxillofacial Plastic Reconstructive Surgery Vol.18 No.4

The term osteomyelitis literally means inflammation of bone marrow. It is described as an inflammatory condition of bone primarily engaging the medullary Following circulatory collapse and ischemia, the involved portions of the bone become necrotic. Cellulitis and osteomyelitis are the most frequent complications of fractures of the mandible and maxilla, because there is an abscessed tooth in the line of fracture. Since most fractures are compound fractures, infection may develop because of contact with oral secretions or outside air. The treatment of chronic osteomyelitis is still under debate. Some authors rely on antibiotics alone, while others advocate combination with surgery. But when infection occurs, establish proper drainage and administer antibiotics. Author treated a case of infected mandibular fracture with mandibular osteotomy, sequestrectomy, iliac bone graft and hyperbaric oxygen therapy, who had suffered suppurative osteomyelitis and mandibular nonunion following the open reduction of the mandibular fracture.

尹志洪,朴奎殷,金奎用 제주대학교 1982 논문집 Vol.14 No.-

Ni-Zn Ferrite는 1200℃이상의 온도에서는 소결성이 좋으며 Bi₂O₃를 첨가하여 소결한 것은 1250℃에서 최대투자율 2050을 얻었으며 보자력은 0.13 Oe로서 가장 낮은 값을 나타내었다. 그러나 주파수에 따른 초투자율은 높은 주파수 영역에서는 다른 조건에서 소결시킨 시료에 비하여 낮은 값을 가진 것으로 나타났다. 사용되는 주파수의 영역에 따라서 적절한 소결온도, 적절한 첨가물이 결정될 수 있을 것으로 예상된다. The magnetic properties of Ni-Zn ferrites with additive(Bi₂O₃;0.3wt%)and without additive have been measured. The maximum permeability is 2050, the initial permeability is 1538 at 1.55MHz and the coersive force is 0.130Oe.

윤율로,송규상 충남대학교 의과대학 지역사회의학연구소 1992 충남의대잡지 Vol.19 No.2

Using a silver staining technique, nucleolar organizer regions(AgNORs) were identified in routinely processed paraffin sections of transitional carcinoma of baldder which were selected from the 37 patients diagnosed in the Depart. of Urology, Changnam University Hospital, during the period July 1986 to July 1992. The technique showed as follows. 1. Argyrophilic nucleolar organizer regions(AgNORs) were seen as sharply defined dark brownish dots in the almost all nuclei of tumor cells. The nuclei were stained as brownish color and cytoplasms as more light brown color. 2. The Mean scores of AgNORs were 1.07 ± 0.04 in Chronic cystitis, 1.52 ± 0.31 in Grade Ⅰ, 1.99 ± 0.04 in Grade Ⅱ, 3.21 ± 1.20 in Grade Ⅲ, 5.24 ± 1.20 in Grade Ⅳ of the transitional carcinoma of the bladder. Using Kruskal-Wallis test the mean scores of AgNORs among each group showed a statistically significant differences(P value < 0.001). 3. The mean scores of AgNORs of each stage of tumor 2.61 ± 1.44 in Stage Ⅰ, 2.56 ± 1.20 in Stage Ⅱ, 3.40 ± 1.99 in Stage Ⅲ, 3.76 ± 1.37. There was no statistical significant differences among the each group of stage(P value > 0.5). 4. No significant correlation was obtained between AgNORs and tumor size or number. 5. The well defined inverse relationship was observed between AgNORs numbers and their sizes. The numbers of AgNORs rises with decreasing differences and increasing malignancy. Thus, the standardized assessement of argyrophilic nucleolar organizer regions can be easily performed by any surgical pathology laboratory without specialized equipment and may be useful as an good indicator of proliferative activity of tumor cell or biological behavior.

윤도영,조규택,송항옥 光云大學校 1995 論文集 Vol.24 No.-

In the present study, onset conditions and transfer characteristics have been investigated experimentally through electrochemical technique. Cupric sulfate-sulfuric acid solution confined between two horizontal copper electrodes was used. The magnitude of current estimating transfer rate was measured at an adopted constant electrical potential. Due to the change of the polarity of electrodes, the diffusion and natural convection have been induced respectively. The dimensionless onset time and correlation equations were as follows. r=70.57Ra-? Sh=0.04731Fa? Above results have differences comparing with existing data which ignore the electrical migration effects. It is considered that the difference between ours and others comes from the effects of migration which we have applyed quantatively. Also, it is ween that the electrical migration not only retards the onset of natural convection, but reduces the transfer rates.

As the technique of automobile industry is being advanced, the advancement of performance for vehicle is being required. In order to achieve this purpose, the study on the handling and stability which are produced by moving vehicle is carried out actively. Ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers. From the previous research. we showed that handling simulation tool developed for J-turn and lane change maneuvers on ADAMS could be used in predicting the performance difference among tires with different specifications in vehicle mild handling behaviors. Through this study, some meaningful correlations were achieved. Also barriers to direct application of the simulation technique to tire development process and several technical problems that should be resolved were iden tified. In this results, ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers.
