복합레진을 이용한 수복은 재료의 낮은 강도와 중합수축으로 인한 변연 누출 그리고 상아질과의 결합력 등으로 인해 제한된 범위에서만 사용되었으나,최근 물성의 향상 및 상아질 결합체의 발달로 심미수복이 필요한 여러 부위에 이용되고 있다. 반직접법을 이용한 레진 인레이는 와동의 크기가 너무 크거나 직접 수복이 곤란한 경우 사용될 수 있으며,어린 환자의 영구구치 수복시 적절한 비용으로 가급적 오랫동안 보철치료를 받지 않고 사용할 수 있도록 한다.반직접법의 장점으로는 중합수축으로 인한 변연누출이 적고,2차 중합을 통해 중합도가 증가하여 강도가 증가되며,간접법시 필요한 기공실 과정이 불필요하여 1회의 내원으로 치료 가능하다는 것 등이 있다. 본 증례는 심미적 치료를 원하는 환자의 구치부 수복시 반직접법을 이용한 레진 인레이를 사용하여 양호한 치료결과를 얻었기에 이를 보고하는 바이다. Msterials for posterior teeth includes amalgam,gold inly and composite resin inlay.Amalgam and gold inly have unsatisfying esthetics.And because they simply obturate the cavity preparation ,they do not strengthen the remaining tooth structure. Posterior composite resin has become established in recent years.However,its polymerization shrinkage and insufficient wear resistance were the most undesiable chracteristic.The physical and mechanical properties of the composite resin inlay are further improved through heat treatment in an oven.The major part of polymarzation contraction of the resin inlay takes place before cementation ,and possible gap formation is only due to shrinkage of the thin layer of resin cement. With the semidirect technique,the inlay meterial is placed directly in the prepared tooth,and the primary polymerization is made by light activation with a handheld curing unit.Additional curing may take place extraorally with use of different curing ovens.It provides the patient with the benefits of luted restorations without the procedure of indirect lab-made inlay. I report three successfully treated cases by semidirect resin inlay technique.Entire clinical steps are described in detail with some discussion on the outcome.

For the study on the changes of Paneth cells and paneth cell granules in small intestine of rats(Sprague Dawely, male, b.w. 200gm±10gm) after common bile duct ligation, the rats were sacrificed at 5, 15, 30 and 45 days after operation, and removed duodeum, jejunum and ileum. Tissues were fixed with 10% neutra formalin solution for over 24 hours. After PAS reaction, Paneth cells were counted within well defined intestinal crypts and the Paneth granules were classified as type I, Ⅱ and Ⅲ according to the granular size and distribution within the cytoplasm. The results were as follows; 1. Paneth cell indices of duodenum and jejunum were decreased significantly from 15 days after common bile duct ligation to 45 days. 2. Paneth granular in dices of duodenum and jejunum were decreased significantly from 15 days after common bile duct ligation to 45 days. 3. Goblet cells were increased in the base of crypts of duodenum and jejunum after common bile duct ligation from 15 days to 45 days.

Whole soybean milk is a functional soymilk produced by mixing of soymilk and Bejee (soymilk residue) slurry. Application of enzymatic technology for disintegrating the coarse and fibrous materials in soymilk residue, and development of biomill reactor for reducing reaciton time make possible to produce new soymilk in domestic industry. Whole soybean milk is environmental affiliated product without discharging any waste such as Bejee ets. Whole soybeen milk has good taste and flavour without coarse mouthfeel induced by including Bejee particle, as well as contains more dietary fiber, protein, oligosaccharide, and other functional compounds than general soymilks. Important values of whole soybean are utilizing all nutritional properites from whole soybean without dicarding any of the insoluble solid. In this study, producing technologies and nutritional properties of whold soybean milk were investigated.

A study was undertaken to evaluate the efficiency of the sytobrush compared with the cotton swab for obtaining cells from the uterine cervix. In 300 patients, the cytobrush technique was employed and in control 300 patients was smeared by the cotton swab. In 12 out of 300 patients(4%) endocervical cells were found on the cotton swab technique. A total of 252 out of 300 cytobrush sampler specimen(84%) contained endocervical cells. With the X²method for statistical comparison, the difference in endocervical cell yield between the cotton swab and the cytobrush sampler was significantly different(p<0.01). This was particularly true in older patients. We conclude from study that the cytobrush sampler is of value for obtaining as adequate cervical cytologic specimen.

Soybean isoflavones have the important physiological functions in the prevention and treatment of chronic diseases. Isoflavone contents of Korean soybean cultivars grown at different locations were determined by HPLC analysis. Total isoflavone contents of 38 Korean cultivars grown at Suwon varied from 50.2 to 275.9 ㎎ per 100g seed meal. The malonylated isoflavone glycosides, which comprised near 80% of the total isoflavone contents, were the major isoflavone constituent in soybean seed whereas acetylform were detected as minor group. Soybean grown at Suwon shows a general decrease for contents of all isoflavone components than that of grown at Chulwon. It maybe concluded that the climate condition could be also the attribution factor to variation in soybean isoflavone contents.

Purpose: This study compared the value of ultrasonography(US) in the diagnosis of sternal fractures with those of conventional radiography and bone scan. Material and Method: From March 2000 to March 2001, in Gil Medical Center, Gachon Medical College, 44 patients(22 women and 22 men, mean age 46 years, range 5∼81 years) complained of tenderness in the sternal area. The cases histories of these patients with clinically suspected sternal fracture due to blunt trauma were prospectively studied. At the time of admission, conventional radiography(sternal view) was done. At one day after admission, sternal ultrasonography was obtained, and after 4∼5 days, a bone scan was done. Sternal ultrasonographic findings, conventional radiographic findings, and bone-scan findings were compared. In addition, a 12-lead ECG was done. When it was necessary, cardiac enzyme was checked and echocardiography was performed. Result: In 21 of 44 patients(48%), a sternal fracture was found by sternal US. Only 9 of 21 patients (43%) were diagnosed as having a sternal fracture by using conventional radiography. 23 of 44 patients (52%) have negative findings on sternal US; they also had negative findings on conventional radiography. Except for 7 unchecked patients, 13 of 21 patients(62%) were diagnosed as having a sternal fracture by bone scan, and among the 23 patients who had negative findings on sternal US, the 19 patients checked with a bone scan also had negative findings. Conclusion: Sternal US can find sternal fractures that are difficult to find on conventional radiography. Compared with bone scan, sternal US takes a shorter time and sternal US is not difficult. Additionally, combined lesions with sternal fractures(peristernal hematoma, soft tissue swelling) and costar cartilage fractures are diagnosed more easily when using sternal US.

Recently HIV infection has been increasing in Korea and recognized as one of the serious social problems. In the current situation in which any effective treatment or preventive vaccine for AIDS has not yet been invented, the most important method of control to reduce the chances of HIV infection is through the continuous education about AIDS. Hospital workers are one type of group which are at a high risk for HIV infection and to some degree resposible for the transmission of AIDS. This study was carried out to provide data to help educate hospital workers prevent the AIDS transmission. For this study, 409 workers from 18 hospitals in the Seoul area were asked to answer the questionaire. The results obtained are as follows : 1. Most respondents (97.8%) knew that AIDS is Acquired Immune Deficiency Syndrome. And 85.6% of respondents knew exactly (71.4%) or roughly (14.2%) about the general characteristics of AIDS. 2 . 68.6% of the respondents knew the route of HIV infection. A lot of people thought that one could be infected by AIDS through utensils, foods, coughing or sneezing. 3. Respondents with high education knew relatively well about the causes of AIDS, compared with those with low education. Males generally understood the characteristics about AIDS better than females. As for the age group, the people in their thirties knew more than those in any other age group. Whereas average income amount, marrige status, or overseas travel experience showed no correlationship with the knowledge about AIDS. 4 . It was observed that males(36.5%) had more experience wity blood donation than females (8.8%) . 83.8% of females thought that they need not take the blood test to be examined for HIV infection, which was higher compared to the 62.3% of males. 5. Mass communication was the main source to provide the information about AIDS for the respondents. Most of the respondents hoped that the hospital where they worked or any other clinic would provide them with more detailed information about AIDS. 92.8% of the respondents insisted that AIDS patients should be isolated to prevent the AIDS transmission.
