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.

As the semiconductor wafer is required to be thinner for better compactness and higher integrity of the electronic products, mechanical dicing saw technique using the diamond blade is facing serious problems such as low cutting speed, tool wear, side wall crack and back side chipping. Recently, UV laser dicing process has emerged as an alternative methods to the blade dicing especially for the very thin wafers below 100㎛. In this study 355 nm UV laser dicing system has been developed in order to improve the productivity and reliability of ultra thin wafer dicing process. For the quality improvement of the developed dicing system various laser parameters are investigated such as power, speed and frequency of the laser beam. Moreover various measurement techniques are employed to evaluate the dicing quality using optical microscope, SEM and focused ion beam.

적절히 치료받지 못한 유치의 치수 감염은 치근단 주위로 확산되고 그 치근단 병소는 계승 영구치의 조기 맹출, 법랑질의 저형성이나 저석회화, 발육정지 등의 합병증을 야기할 수 있다. 특히 유치의 치근단 감염은 계승치의 변위를 야기할 수 있으며, 계승 영구치배의 위치변화는 선행 유치의 치수변성으로 인한 것이 가장 많다. 본 증례보고는 하악 유구치의 치근단 병소에 의해 계승치가 변위된 경우로서, 증례 1은 하악 우측 유구치 하방의 치근단 낭에 의한 계승치의 변위가 관찰되어 유치 발치 및 조대술을 시행한 후 obturator를 장착하였고, 증례 2는 하악 우측 제2유구치 하방의 치근단 농양에 의한 계승치의 변위가 관찰되어 유치를 발거하고 공간유지장치를 장착하였다. 본 증례를 통하여 하악 유구치 치근단 병소에 의해 계승 영구치가 심한 변위을 나타낸 경우, 적절한 치료를 통해 계승 영구치의 적절한 맹출을 유도할 수 있었기에 보고하는 바이다. Primary teeth and the permanent successor must be understood as interdependent units, where each one of them interacts with and depends upon the other. The spread of pulpal inflammation in primary teeth to the periradicular tissues can lead to early eruption, enamel hypoplasia or hypocalcification, developmental arrest of permanent successor. Also the periapical inflammation cause permanent tooth displacement in various direction. We describe here two clinical cases of displaced permanent successor caused by periapical lesion of mandibular primary molar in children.

The left aortic arch with an aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5-2.5% of individuals. In such cases, the angular course of the arteria lusoria to the ascending aorta imposes difficulty in passing a guide wire to the ascending aorta during right transradial catheterization. Here, the case of a 53-year-old woman with intermittent chest tightness and coughing is reported. Aberrant right subclavian artery(arteria lusoria) was diagnosed via aortogram during right trans- radial coronary angiography. Compression of the esophagus and trachea by the aberrant right subclavian artery was demonstrated by chest computed tomography(CT).

The purpose of the present study was to investigate the factors influencing the adherence. This investigation was based on the social learning theory that the individual characteristics, significant others, and social situation determine the participant's exercise adherence. For this purpose five hundred women were randomly selected from four swimming centers in Seoul. The subjects participated three times a week more than three months. In order to collect the data the items of the questionnaires were selected based on the previous studies(Im, 1987; Yamaguchi, 1987, 1988; Jung, 1991)and were reconstructed through the test of the validity and reliability. The data were analyzed through the one-way ANOVA. The analysis of results provided the following conclusions : The economic level, the degree of the participant's satisfaction for the exercise program, facilities and instructors, participant level of the other swimmers and previous exercise experience made significant influences on the exercise adherence. The other factors did not influence the participant's exercise adherence.

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.

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.

역병 저항성 재료로 도입하여 유지하고 있는 PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29 = AC2258), KC462, KC463, KC464 혹은 이들 유전자원에서 선발한 계통들의 역병에 대한 저항성 검정, 원예적 특성 조사 및 종자 증식을 실시하였다. PI123469, PI201234, PI201232, AC2258, KC823 에서 선발된 계통들이 가장 저항성이 강한 것으로 나타났다. 동일한 유전자원에서 선발한 계통간에도 저항성 수준에서 현저한 차이가 관찰되는 경우가 있었으며, 이러한 경우는 주로 유지 증식과정에 자연교잡이 일어난 결과로 추정되었다. 따라서 순도 높은 저항성 재료를 얻기 위해서는 봉지를 씌워 자식종자를 채종하는 것이 가장 안전하며, 다음으로는 계통 망실 혹은 망상을 이용하는 것이 바람직한 것으로 판단되었다. Resistance to Phytophthora capsici and horticultural characteristics of selections from the resistance sources such as PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29), KC462, KC463, KC464 were evaluated and recorded in the process of seed increase. Selections of PI123469, PI201234, PI201232, AC2258, KC823 (Line 29 = AC2258) of them showed the highest level of resistance. A considerable difference in the level of resistance was observed between lines selected from the same sources. The variation between selections derived from the same source was thought to ve attributable to natural cross-pollination that may have occurred during the seed increase. Therefore, securing self-pollinated seed by wrapping the flower buds before anthesis would be necessary to obtain genetivally pure resistant lines. The next alternative would be to increase the seed in small net houses for single line or field cage.

Objectives: This paper aims to describe an outcome-based curriculum development process at a medical school that has difficulty in advancement from the higher stage outcomes to the individual lesson outcomes, and to propose a way to implement it practically. Methods: We reviewed the objectives, strategies and previous products of the school’s taskforce activities and suggested the principle of bidirectional approaches of outcome based curriculum development. Results: The developing strategy identified such as firstly, the evaluation of present curriculum and then, the review of the outcomes developed previously with considering the nation-wide environmental change in medical education. Then, we selected one example course which was focused the resources of the school to, and finally the product of the example course was propagated to the other courses with central monitoring. Conclusion: Bidirectional model of ‘Top-down’ plus ‘Bottom-up’ approaches could be an efficient way to develop the outcome-based curriculum in a medical school, which has difficulties to advance the developing process due to various reasons including limited resources.

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.
