According to the development of operation technique and biologic materials, oromaxillofacial surgery department have used many kinds of metal and biologic materials in ORIF and plastic surgery. In maxillofacial fracture, ORIF with metal plate and screw have short healing period and good prognosis. But ORIF with metal materials have many complications as maxillofacial abnormal growth, screw loosening, bone malunion. And metal materials have not used in infection site. The purpose of this study is to evaluate the clinical value of 10 condylar fracture patients operated with absorbable screw at Wonkwang university. Ten patients(8 males, 2 female, mean aged 28) who had mandibular condyle process fracture treated with PLLA implants(poly-l-lactide) was recalled for follow-up clinical and radiologic examination for 10 years. Mouth opening recorvered to more than 35mm and occlusion was stable in all patients. All fractured mandibular condyles showed anatomic good reduction and long-term stability with the use of resorbable miniplates and screw. Bone healing was satisfactory in all patients, and there was no evidence of abnormal resorption of condylar process.

스프린트는 치주처지료에서 부가적 처치법으로 널리 사용되고 있으며, 한편, 디지털 공제 활영술은 기존방사선촬영술의 한계점을 극복하기 위해 기발된 새로운 방법이다. 이번 연구에서는 치근활택술 단독시행시와 스피린트 병행 처치시의 효과를 임상적, 방사선학적으로 비교하였다. 중정도의 성인성 치주염을 가진 20명의 환자를 대상으로 하되 10명은 치근활택술 단독으로, 나머지 10명은 스프린트 병행처치로 처치하였다. 임상적, 방사선학적인 평가는 처치전, 처치후 6개월에 행하고, 임상적 평가의 경우 3개월에 추가로 실시하였다. 이번 연구에서 사용된 임상 지수로는 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상부착수준, 임상부착증가, 탐침시출혈, 치아동요도 등이며, 방사선학적 평가는 기존 방사선촬영술에 의한 방법과 디지털 공제촬영수렝 의한 방법으로 행하였다. 디지털 공제 촬영술에 의한 평가시, 영상은 Digora 프로그램에 의해 획득하고 Emago 프로그램으로 처리 하여 다음과 같은 결론을 얻었다. 1. 처치후 3개월에 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상적부착수준, 탐침시 출혈 등의 임상지수들이 변했으며, 특히 이러한 변화는 치주낭깊이, 치은퇴축, 탐침시출혈에서 유의성이 있었다. ( p<0.05 ) 그러나 두군간 차이는 인정되지 않았다. ( p>0.05 ) 2. 처치후 6개월에도 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상적부착수준, 탐침시출혈, 치아동요도 등의 임상지수들이 변했으며, 특히 이러한 변화는 치주낭깊이, 치은퇴축, 탐침시출혈, 치태지수, 치아동요도에서 유의성이 있었다. ( p<0.05 ) 그러나 두 군간 차이는 인정되지 않았다. ( p>0.05 ) 3. 켄달 상관분석시, 임상적 평가와 기존 방사선 촬영술에 의한 평가사이의 관련성을 낮았으며 거의 0에 가까운 수치를 보였으며 (r=0.110, p=0.639 ) 임상적 평가와 디지털 공제 방사선 촬영술에 의한 평가사이에서 약간 높은 관련성을 보였다. ( r=0.257, p=0.315 ) 즉 치주치료후의 골변화는 디지털 공제 방사선 촬영술에 의한 평가시 기존 방사선 사진보다 임상적 부착증가와 더욱 긴밀한 관련성을 보여준다. 이상의 결과로 볼 때, 스프린팅 처치는 치주 치료에 있어 치근활택술에 부가적 표과를 제공하지 못한다.

Hydrogen adsorption mechanism onto the porous metal-organic frameworks (MOFs) has been studied by density functional theory calculation. The selected functionals for the predict ion of interact ion energies between hydrogen and potential adsorption sites of MOF was utilized after the evaluation with the various functionals for interaction energy of H₂C<sub>6</sub>H<sub>6</sub> model system the adsorption energy of hydrogen molecule into MOF was investigated with the consideration of the favorable adsorption sites and the orientations. We also calculated the second favorable adsorption sites by geometry optimization using every combination of two first absorbed hydrogen molecules. Based on the calculation of first and second adsorption sites and energies, the hydrogen adsorption into MOF follows a cooperative mechanism in which the initial metal sites initiate the propagation of the hydrogen adsorption on the whole frameworks. In addition, it was found that the interaction strength between the simple benzene ring with hydrogen is significantly reinforced when the benzene ring has been incorporated into the framework of MOFs.

The purpose of this study was to inquire educational meanings of overseas field exercise on the assumption that overseas field exercise for amateur golfers is one of educational phenomena. The results could be summarized as follow: First, according to guidance instructor, the educational purpose is to `cultivate learners of self-initiative.` The guidance instructors were in agony regarding education, and those agonies became strategies of teaching self-initiative in details. The strategies of teaching self-initiative were the center of attention in this study. It was observed from the perspective that emphasizing `put a vision into practice.` In addition, the golfers had various feelings, and they kept reminding themselves `to learn more than` just skills, knowledge, or tournament tactics through the field exercises. Second, the activities and behaviors of guidance instructors during overseas field exercises were observed as teaching strategy in order for them to emphasize the meaning of self-initiative. Moreover, learners, on the other hand, also had their own studying strategies by experiencing the field: fun and duty.

The area of Mt. Ungil in which the experiment forest of Dongguk University is situated has abundant rainfall as well as proper amount of moisture and humidity due to the nearby flowing Han River and Jin-joong Cheon. This climatic and geographic factors provide the forest with an ideal condition for tree-growing, which has resulted in the growth of a variety of trees in that area. Since the Kwang-joo mountains stretch toward north-east, the school forest is well connected with the surrounding forests, and thus various wild trees and plants are evenly distributed in the area. The range of plants living in the area was surveyed from summer to autumn of 1983, and it was found that is consists of 64 families, 259 genera, 397 species, 60 varieties and 3 kinds.
