하악 제 1대구치 매복의 발생 빈도는 전체 인구의 0.01%로 드물게 나타난다. 매복의 원인으로는 맹출 공간의 부족, 과잉치, 치성 종양이나 낭과 같은 맹출로상의 장애물, 유전적 요인, 내분비 질환, 외상 등이 있다. 하악 제 1대구치의 매복으로 인해 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 부작용이 생길 수 있으며, 치료 방법으로는 외과적 노출술, 교정적 견인, 외과적 재위치술, 발거 등이 있다. 다음의 두 증례는 하악 제 1대구치의 미맹출을 주소로 내원한 환아에게 외과적 노출술을 시행하여 원심 경사 매복된 하악 제 1대구치의 자발적 맹출을 유도한 증례들이다. Impaction of mandibular first molar is relatively rare and its overall frequency has been reported to be 0.01%. The etiology of impaction are lack of eruption space, physical obstacles such as supernumerary teeth, odontomas or odontogenic tumors, hereditary factors, functional disturbances of endocrine glands and traumas. Impaction of mandibular first molar can result in a short lower facial height, formation of a follicular cyst, pericoronal inflammation, resorption of the roots of neighboring teeth and malocclusion. The treatment options available for impacted teeth include surgical exposure, orthodontic forced eruption, surgical repositioning and surgical removal of unerupted molar. This report presents two cases of distally tilted and impacted mandibular first molars which were treated by surgical exposure. In these cases, we could observe spontaneous eruption of the impacted mandibular first molars after surgical exposure.

This paper focused on the application at actual teaching field in the way of performance assessment that lately entered the stage as an alternative plan traditional way of evaluation at the 5th grade social studies economic area in elementary school. This paper presented the ground of an argument of performance assessment introduction based on a developmental evaluation view, cognitive psychology and multi-intelligence theory. Constantly to be feed back the goal of social studies economic education, guidance content, evaluation, we established the goal of social studies economic education and analyzed the content of economic education by ten pieces of basic concept in the 5th grade social studies elementary school. On the basic of these, we reconstructed by 8 pieces of basic concept against being guide at the 5th social studies curriculum now in use. One hand for the development of performance assessment of economic area, this paper utilized the existing techniques of performance assessment and made a criterion plan of the performance assessment . on the basic of this. We projected the way of performance assessment by basic concept. The result is as follows First, The production of a criterion plan of performance assessment can be a suitable tool of performance assessment. Second, if we used compound numbers technique of performance assessment, the result of evaluation would bring along the synergy effect. Third, we extracted the economic basic concept against being guided to the 5th grade in the elementary school. For further more studies, this paper suggests that the test way of performance assessment must be exploited as possible as early to know how much contribute to make progress higher order thinking like originality and problem solving capacity to information-oriented society and knowledge foundation society in the coming up.

경남지역과 충북지역 감나무의 재배, 해충 방제실태를 농가 방문하여 설문조사 한 결과 감 재배경력은 경남지역이 평균 10년이며, 충북지역은 평균 5년 정도이다. 감 재배 주수는 대다수 농가가 20주 이상이고, 재배관리에 대하여 자문을 받는 곳은 농업센터나 농약사 및 연구소 등이었다. 김 품종은 경남지역에서는 부유와 서촌조생, 충북지역에서는 등시와 월하 등을 재배하고 있었다. 시비종류는 이른봄 에 퇴비나 복합비료를 주었고, 감나무 생장 중 열매나 저장 중 열매에 발생하는 해충이 발견되었다. 해충방제를 위해 살충제를 살포하고 있는데 주로 감꼭지나방, 진딧물, 잎말이나방 및 깍지벌레 등으로 파마치온, 파단, 코니도, 신파마치온, 수프라사이드 등을 살포하였다. 감꼭지나방(Stathmopoda masinissa)의 발육생태를 조사하기 위하여, 감꼭지나방을 야외에서 채집하여 온도±1℃, 광주기 16L:8D, 상대습도 50~60%에서 실내 사육하였다. 각 층태별 기간은 알 7.4일, 유충기간 34.7일, 용 15.5일이었다. 각 령기간은 1령 3.5일, 2령 4.2일, 3령 5.2일, 4령 6.5일, 5령 15.4일이었으며, 특히 유층의 두폭을 측정하여 평균한 결과는 1령 0.20mm, 2령 0.40mm, 3령 0.65mm, 4령 0.87mm, 5령 1.07mm일 이었다. 성충의 수명은 수컷이 6.2일, 암컷이 10.1일 이었다. 용화율은 68.0% 우화율은 59.9%이었다. A survey in Kyungnam and chungbuk areas revealed that the average number of years for persimmon tree farming is 10 and 5 years, respectively. The number of trees per orchard is at least over 20, and the farmers have been usually advised through an agricultural center, an agrochemical store, or agrochemical research center. The varieties of the persimmons they grow are Buyu and Seocheon in Kyungnam, and Doogsi and Wolha in Chungbuk. The kind of fertilizers they sprayed in early spring is either compost or composite fertilizer. persimmon pests are often found in persimmon fruits while on a tree or in storage. Phamathion, Padan, Konido, Sinpamathion, and/or supuraside is usually used to control persimmon fruit moths, aphides, leafrollers, and scale insects. To understand the developmental ecology of the persimmon fruit moth, Stathmopoda masinissa Meyrick, we collected and reared them under the laboratory condition which is at 25±1℃ of temperature, 16L:8D of photoperiod, and 85% of relative humidity. As a result, the developmental period of egg, larva, and pupa were 7.40, 34.7, and 15.5 days, respectively. The average period of each larval instar was 3.50, 4.17, 5.17, 6.46, and 15.42 days, respectively, and the average head capsule width was 0.20, 0.40, 0.65, 0.87, and 1.07mm, respectively. The average adult longevity was 6.2 days for males and 10.1 days for females. The pupation rate and the emergence rate were 68.0% and 59.9%, respectively.

The authors have made and attempt to examine the transition of the leading causes of death in Korea recently since 1984 by analytically reviewing the annual statistical data on the causes of death for the latest ten years reported mainly from the National Statistical Office and other informative materials. The results were summarized as follows: 1. After the inverting period of the 1970s and early 1980s changing remarkably from the communicable to the non-communicable disease, the leading causes of death were changed to the chronic degenerative diseases such as circulatory disease and malignant neoplasms recently. 2. With the particularly increasing deaths due to the unintentional accidents since the mid-1980s, circulatory disease, malignant neoplasms, and accidents became the three leading causes of death, and accounted for about 66.5 percent of the total deaths in 1993. 3. Concerning the sex-specific leading causes of death, currently they were malignant neoplasms, accidents, cerebrovascular disease, chronic liver disease, and heart disease in males, and cerebrovascuar disease, malignant neoplasms, heart disease, accidents, and hypertensive disease, malignant neoplasms, heart disease, accidents, and hypertensive disease in females in that order respectively. 4. As to the leading causes of death by the age-groups, they were congenital anomaly and infectious disease at infantile age; accidents and unintentional injury at ages 1-39year: malignant neoplasms, circulatory disease, and chronic degenerative disease at ages 40-69years; and circulatory disease, senility and other chronic degenerative disease at ages 70 and over respectively. 5. In reviewing the transition of the leading causes of death, communicable diseases formidably prevailed for the past decades were rapidly decreased recently, and chronic degenerative disease, So-called, "Chronic Illness" such as circulatory disease, malignant neoplasms, and chronic pulmonary disease are in tendency of continuous increase year by year. Although chronic liter disease seems to be stationary in incidence now-a-days, additionally, its level of death is still relatively high. And the death rates due to all kinds of accidents are remarkably increasing. Overall, accidents and unintentional injuries were the third leading cause of death and accounted for about 15 percent of the total deaths.

The purpose of the study was to correlate margin design(chamfer, shoulder, shoulder with a 45℃ bevel) with the seating and sealing of cemented full cast crowns under standardized simulated clinical conditions. Wax patterns were mode with milled stainless-steel dies and rings, and were invested, burnt out, and cast, The full cast crowns were cemented on individual resin dies, and a gradually diminishing load(45㎏ to 25㎏) was applied over a 10-munite period. The specimens were sectioned centrally with a low speed saw and examined with a light microscope. The results were as follows: 1. Chamfer preparations demonstrated it was the best marginal seal, followed in order by the shoulder with a 45° bevel, and by the shoulder(p<.05). 2. Chamfer preparations demonstrated it was the best occlusal seating, followed in order by the shoulder, and by the shoulder with a 45° bevel(p<.05). J. Kyungpook Nat. Univ. Sch. Dent.
