This treatise is dealing with the political systems of four scandinavian countries-sweden, Denmark, Norway and Finland. Five Parties and two political blocs have long dominated the Scandinavian political landscape. The Conservative, Hiberal, and Agrarian of Center parties form one cluster, the Labor (Social Democratic) and Communist parties one another. This Kind of configuration suggests the predominance of a socialist nonsocialist cleavage thoughout Scandinavian countries. Party programs lend support to this notion as does electral behavior. Class is still the major determinant of voting behavior in these countries. The five party system is the product of long term realignments along the left-right dimension. The presense of more than five parties constitutes a deviation from the model. Sweden complies with the above criteria. But the other countries do not comply with it. Denmark's fit with the model is good but not excellent. Norway ranks next to Denmark. Finland stands out as the deviant case, The Finnish party system is apparently the product of three dimensions, There is the well known cleavage between Finish-and Swedish-speakers, There is an urban/rural cleavage and, a left-right dimension. The activities of political parties coalitions and the parliamentary are also dealt with. In the last chapter the party organization and fund are analysized. The political party stystem is characterized by the multi-party-system, therefore the politscal situation is mually not stable.

This survey is based on questinnairs given to the students at Gyeongsang National University during the period from May 22,1972 to May 31, 1972. The subjects were 681 students ranging from freshmen to seniors which consisted of 70.2 percent of the total sutudent enrollment at Gyeongsang National University. The purpose of the survey is to gather some information to solve the problems of the students at Gyeong sang National University through the close examination, analysis and understanding of the problems of the students. According to the survey 50 percent of the students showed dissatisfaction with college life. Moreover 44.4 percent of the students wanted to transfer to another department. It is, therefore, very much desirable to make a further study on the problems and to provide proper guidance for those students with problems. The relationship between professors and students in rather distant. The students want to have frequent out of class diologues with their professors. One third of the students have problems in inter-personal relationship with their friends and professors, Extra-curricular activitities are stagnant. As regards to these problems, the student guidance center should cooperate closely with each individual department at the college. They should take the students' suggestions into consideration. It is necessary to chance the active concern and participation of professors and school administrators in these problems with further study and guidance under the student guidance center for more effective guidance services.

측모두부방사선사진의 중첩만으로는 교합평면상의 치아이동을 알 수 없으며, occlusogram 역시 촬영 및 중첩의 오류를 피할 수 없다. 본 연구는 석고모형의 3차원 영상을 촬영한 후 3차원 영상 소프트웨어를 이용하여 중첩된 영상을 통해 상악 소구치 발치공간 폐쇄 후 상악 구치부 회전양상을 알아보고자 하였다. 성인여성 19명을 연구대상으로 하여 치료 전 석고모형 및 치료 완료후 석고모형의 3차원 영상을 촬영한 후, 상악 경구개면을 기준으로 두 영상을 중첩한 다음, 치료 전후의 상악 구치부의 회전양상을 비교 분석하였다. 연구결과, 구치부의 회전 양상은 매우 다양하였다. 그 주요 원인은 치료 전 상악 구치의 다양한 회전 상태와 치열궁 및 치아의 형태학적인 특성 때문인 것으로 추측되었다. 따라서 발치공간 폐쇄 시 일어나는 구치의 회전 양상을 3차원 영상을 이용하여 정확히 평가하기 위해서는 치료 전후에 일어나는 구치의 회전을 초기 배열 전후의 구치 회전, 발치공간 폐쇄 전후의 구치 회전, 그리고 마무리 단계 전후의 구치 회전으로 세분하여 평가해야 함을 알 수 있었다. Cephalometric superimposition is unable to evaluate tooth movement along the occlusal plane and the errors of photographing and superimposition of the occlusogram is also inevitable. The purpose of the present study was to evaluate the rotational movements of the maxillary posterior teeth following space closure after extraction of maxillary first premolars, using 3D dental images. In 19 adult females, analysis of rotational movements of the maxillary posterior teeth was performed between the initial and final 3D dental images superimposed on the maxillary hard palate. The results showed a diversity of rotational movements of posterior teeth. The causes of various rotational movements may be different rotation of molars in each case at the beginning of treatment. individual characters of the dental arch and tooth morphology. The results of the study indicate that accurate evaluation of retational movements of posterior teeth following space closure after extraction of premolars using 3D dental images can be obtained through the subdivision of tooth movement during the initial aligning, space closure and finishing stages.
