The purpose of this study was to collect basic data for the development of oral health education program of parents and to encourage their actual interest and participation in school oral health program. The authors surveyed parents' awareness and behaviors about the oral health of their children. The subjects in this study were 193 parents of elementary school children in Seoul. The collected data were analyzed, the obtained results were as follows: 1. Thirty-five percent of the parents investigated paid a regular visit to a dental clinic. The must common tooth brushing time among them was after dinner, the second was after breakfast, and this was followed by before bedtime and before breakfast. 2. Ninety-four percent of the parents responded that prevention is necessary, 92.2% had a plan to visit a dental clinic to prevent dental caries, and 60.1% experienced receiving pit and fissure sealants. Ninety-seven percent responded that they did check their children's dental caries. 54.9% chocked their children's oral status after tooth brushing. The parents who visit a dental clinic on a regular basis were more likely to check their children's teeth after tooth brushing than those who don't(P<0.05). 3. Eighty eight percent of respondents wanted to keep the fluoride mouth rinse program. 4. It is recommended that an oral health education program be developed for parents to visit dental clinics on a regular basis, to educate as to the right tooth brushing time, and to check out their children's oral status after tooth blushing.

The purpose of this study was to collect basic data for the development of effective oral health education program in elementary school. The subjects in this study were 604 fourth-year, fifth-year and sixth-year students of an elementary school in Seoul. Oral health awareness and behaviors were surveyed and analyzed. The findings of this study were as follows: 1. The most common time for toothbrushing was after dinner(62.0%) and before bedtime(62.3%). By school year, the largest number who brushed their teeth after dinner were fourth and fifth graders while the greatest number who did so after breakfast were sixth graders Seventy-four percent of respondents brushed the teeth twice or more a day. By school year, the fifth-year students brushed their teeth the least while girls outperformed the boys in daily toothbrushing frequency(p<0.05). Regarding the intake of cariogenic food, 62.1% took that kind of food once or more a day. By school year, the fifth graders took the most (p<0.05), and girls took more cariogenic food than the boys(p<0.05). 2. Ninety percent of the respondents had visited a dental clinic. By grade, the sixth-year students had visited a dental clinic more frequently and girls more frequently than boys. Eighty percent of the respondents visited a dental clinic to receive treatment but just 12.3% visited a dental clinic to prevent oral diseases. Concerning the fetor of dental treatment only 14.4% expressed fear. School year made no difference, yet the percentage of girls who experienced fear was higher than that of boys(P<0.05). Regarding preventive treatment, 39.7% experienced pit and fissure sealing and 24.2% experienced the application of fluorides. All the students hadn't much experience in preventive treatment regardless of school year -- gender didn't make a difference. 3. Fourty-six percent of respondents had a preference for the fluoride mouth rinsing program; 38.4% wanted that grogram to continue. As to the reason for preference, 38.2% preferred it because of the prevention of dental caries, 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do(some of the respondents gave two different answers). 4. Despite an increase in the frequency of toothbrushing at the right time, they still took cariogenic food frequently Their visit to a dental clinics also aimed at treatment more than at prevention, and they had very narrow experience of preventive treatment. Furthermore, the fluoride mouth rinsing program failed to draw their interest. Therefore, it is recommended that a successful real health education program should be developed.

Thirty five patinets' paraffin embedded biops block , which was previously diagnosed ameloblastoma and obtained from oral and maxillofacial surgery dept. of pusan paik hospital and OMS dept of collage dentistry, pusan national university hospital, from January 1994 to march 1999, were performed immunohistochemistry with p-53 and MIB-1. On investigating the expression, correlation between clinical and histologic factor and correlation between prognosis and moleculopathologic property were examined. And we obtained the following results; 1. Age over forty, recurrence rate was 58.5%. 91.4% of the tumor was developed on mandibule, recurrence rate of maxilla area tumor was 66.7% On radiologic and histologic feature, multilocular and follicular type has high recurrence rate but no significance statistical difference was found 2. Expression of p-53 was 25.7%, When underage of forty. location on mandibule, multilocular and plexiform type, the expression of p-53 was somewhat higher and recurred cases of tumor, expression rate was 12.5%. 3. MIB-1 expression rate was 77.1%. When location on mandibule, unilocular, plexiform type tumor and previously recurred case, MIB-1 expression was 87.5% which was somewhat higher than no recurrence case of 74.1%. 4. 33.3.% of positive on MIB-1 have expression of p-53 and all p-53 positive case express MIB-1 positive. All p-53 positive case have high cell proliferation rate. From this result, age and location have closely related with the prognosis of tumor, histologic feature and MIB-1 expression has related with the prognosis of tumor. But p-53 has highly expressed on cell proliferation area, not closely related with the prognosis of tumor.

정석찬,한태창,서범수,조장혁,주경준 한국경영과학회 1998 한국경영과학회 학술대회논문집 Vol.- No.1

CITIS(Contractor Integrated Technical Information Service) is a contractor's developed service to provide electronic access and/or delivery of contractually required information. CITIS satisfies one of the major CALS objectives to furnish a single-entry point for authorized access to contractor-generated Contract Data Requirement List(CDRL) data. A critical requirement for the practical implementation of the CITIS concept is the ability to access multiple existing heterogeneous databases in a fashion transparent to the CITIS user. In this paper, we will propose a prototype system model for CITIS, and discuss the system architecture of proposed CITIS system as a global information management system for distributed and heterogeneous local information systems. Furthermore, we will discuss about the required server module and using-scenario of proposed CITIS system.

The aim of this study was to evaluate the effect of various polymerization techniques on the microleakage of compomer restorations. Fifty extracted human premolar and molar were used and randomly divided into 5 groups. After cavity preparation, compomer (F2000) was filled according to the manufacturer's directions. All groups, except group 5, were filled using an incremental technique. Group 1was polymerized for 40 seconds at a continuous 485mW/㎠ with a VIP (Bisco, USA) light cure unit. Group 2 was polymerized for 20 seconds at a continuous 345mW/㎠ and then for 20 seconds at 645mW/㎠ with the VIP light cure unit. Group 3 was polymerized at 400mW/㎠, gradually increased to 50mW/㎠ per 10 seconds until 550mW/㎠ was reached; total 40 seconds with a Spectrum 800 (Dentsply Caulk, USA) light cure unit. Group 4 was polymerized for for 3 seconds using an incremental technique with a Flipo (LOKKi, France) light cure unit. Group 5 was polymerized for 3 seconds using a bulk fill technique with the Flipo light cure unit. The specimens were embedded with acrylic resin, and were sectioned with diamond saws in a mesiodistal direction along the longitudinal axis of the tooth so as to pass through the center of the restoration, and three surfaces (occlusal, pulpal, and gingival) were examined with SEM. The results were as follows; 1. Group 5 showed a significantly larger gaps compared to other groups on the gingival, occlusal, and pulpal walls. 2. All groups except group 5 had no statistically significant gap on the gingival, occlusal, and pulpal walls. 3. There was no significant correlation between the amount of enamel on the gingival and occlusal walls and polymerization shrinkage.

Objective : Squamous cell carcinoma of the head and neck represents approximately 2.0∼4.0% of all malignant tumors, with an etiology closely associated with smoking, drinking and various genetic alterations. The purpose of this study was to investigate the correlation of MIB-1, p53, bcl-2 and apoptosis according to degree of differentitation of squamous cell carcinoma. Methods and Material : forty-eight cases of squamous cell carcinoma of the head and neck were selected for this study. MIB-1, p53, bc1-2 expression rate were studied by iromunogistochemical staining and the number of apoptosis observed by TUNEL method. Results : The expressioins of MIB-1, p53, bcl-2 and apoptosis were found in 56.3%, 50.0%, 14.6%, 85.4%, of 48 cases of squamous cell carcinoma, respectively. The expression of MIB-1, p53 and apoptosis were more higher in poorly differentiated cases than well differentiated cases. MIB-1 expression was related with p53 mutation (p<0.05) and apoptosis rate(p<0.05). Conclusion : From these results. the expressions of MIB-1, bcl-2 and apoptosis were related with degree of differentiation of squamous cell carcinoma and correlation among these parameters.

조성옥,한헌석,차상훈,이경희,박범수,하태선,채수안 충북대학교 의과대학 충북대학교 의학연구소 1995 忠北醫大學術誌 Vol.5 No.2

신증후군에서는 동맥 및 정맥의 혈전에 의한 혈전색전증의 위험이 높다. 이는 혈 중 응고인자 Ⅰ, Ⅱ, Ⅶ, Ⅷ, Ⅹ등의 증가와 뇨소실로 인한 antithrombin Ⅲ의 감소, 섬유소 용해계의 변화, 혈소판 응집력의 증가에 기인하며 그 외 스테로이드 투여, 이뇨제 투여, 저체액 상태도 관여한다고 생각하나 이런 과응고현상에 대한 정확한 병태생리는 규명되고 있지 않다. 저자들은 내원 21개원 전 처음 신증후군 증상을 보였고 신장 조직 검사상 미세변화 신증후군으로 진단을 받고 스테로이드와 면역 억제제를 사용하였으나 6개월에 3-4회의 재발을 보이던 중 내원 1달 전 보호자 자의로 모든 약물 복용을 중단한 채로 지내다가 고열과 반혼수 상태를 보여 내원한 7세 남아에서 다발성 뇌경객증을 발견하였기에 문헌 고찰과 함께 보고하는 바이다. The risk of thromboembolism by arterial or venous thrombosis is high in the nephrotic syndrome. This may be due to the increased serum concentrations of the factor Ⅰ, Ⅱ, Ⅶ, Ⅷ, Ⅹ etc, decrease of antithrombin Ⅲ due to urinary loss, the change of thrombolytic system, increase in the platelet aggregation capacity, the use of steroid, diuretics, and hypovolemic state. But, the pathophysiology of this hypercoagulable state has not been clear. A 7-year- old boy had been diagnosed as having frequently relapsing minimal change nephrotic syndrome, 21 months ago. In spite of the administration of prednisolone and cytoxan, he had presented recurrent proteinuria in the frequency of 3-4 times per 6 months. From 1 month prior to visiting emergency room, his parents discontinued his medications, therefore, he showed fever and semicomatous mental status. In brain MRI study, multiple cerebral infarcts were noted. So, the authors report a case of multiple cerebral infarcts in a patient with frequently relapsing minimal change nephrotic syndrome with a brief review of related literature.
