In the past the jaw and occlusal relationship in centric occlusion were merely considered in case of orthodontic diagnosis and treatment planning. As the fact that functional disturbance of the temporomandibular joint may be caused by occlusal interference was recognized, the importance of functional occlusion and centric relation is emphasized today. Known the importance of centric relation, there are various opinions about definition of centric relation and its taking methods. The purpose of this study was to investigate the relative centric condyle position and to compare the reproducibility of the recordings utilizing different centric relation records obtained by different taking methods. The 15 adults with normal occlusion were participated in this study. Every four centric relation records were taken in each of three methods - leaf gauge, Dawson and myomonitor method. Then the relative centric condyle position, the distance between the condylar position in centric occlusion and the position in centric relation and the reproducibility were studied using SAM 2 articulator and mandibular position indicator. The results were as follows ; 1. The trend of condyle position was different depending on centric relation taking methods. 2. The position of condyle in centric relation by leaf gauge and Dawson methods was superior to that by myomonitor method, and the position by myomonitor method was relatively antero-inferior. 3. The distance between the condylar positions in centric occlusion and the position in centric relation was longest in myomonitor method. 4. The reproducibility had little differences in transverse direction among three methods, while leaf gauge method showed the highest reproducibility and myomonitor method did the lowest reproducibility in antero-posterior and supero-inferior direction.

Competition of today's markets get to compete the relationship of one system and another system. Competition in relationship of system emphasis molding of cooperate relationship-strycture between enetrprices and It appears competitiveness enriched effects of enterprices in systems. In the rapidly changing economy and marketing situation, Travel agency got worse management situation of themselves more excessive competitiveness then competitiveness efforts between Tourism Relationship Enterprices. So, Relationship marketing will lays a foundation of new travel agency's environment through competitive of relation to travel agency and travel agency, travel agency and hotel or travel agency and airplane. This study's object are present relationships between travel agency and travel relation enterprise of cooperation, complication and competitiveness to relation form. And this study are presents suggestion to generate of hereafter travel relation enterprise through study on relationship with hotel and airplane. A final object of this study are presents a model applys relation method of travel agency and travel agency, hotel and airplane through inspect to specialist analysis. In the result of study, Travel agency are low position and difficult with hotel and airplane at the cooperation but acually It's difficult with travel relation enterprise. So, Travel agency will be operates characteritic system and regulations for win with travel relation enterprise for efficiency of working more than hotel and airplane. Airplane is the best big travel relation enterprise. So, The most airplane has to high cooperate with travel agency. That's why airplane keep going close cooperation with travel agency. Travel agency has to close cooperate with hotels secondly through marketing, exchanging information and union advertisement etc. Hotels are low in complications than travel agency but high in complications than airplane. Although travel relation enterprise are different system individually, because of all of us working with union object, Travel agency and travel compliment-cooperation relationship.relation enterprise has to autonomy behavior with close cooperation through.

본 연구의 목적은 허쉬(Hirschi)의 사회유대이론과 학교적응 영역의 기존연구를 토대로 청소년의 학교적응에 관한 사회적 관계 모델을 제시하고 검증하는 것이다. 사회적 관계 모델에는 부모관계변인, 친구관계변인, 교사관계변인이 포함되었다. 연구 대상은 인문계 고등학교 재학생 351명과 전국 쉼터에 머무르고 있는 청소년 143명으로 총 494명이었다. 자료분석방법으로는 기술통계, 상관관계분석, 중다회귀분석이 사용되었다. 분석결과, 청소년의 학교적응에 관한 사회적 관계 모델이 청소년의 전반적 적응과 학업적 적응(성적)을 설명하는 데 유의미하다는 것이 밝혀졌다. 구체적으로는, 부모와의 관계가 좋을수록, 친구와의 관계가 좋을수록, 교사와의 관계가 좋을수록 청소년의 학교적응도가 높아지는 것으로 나타났으며, 이 중 가장 영향력있는 변인은 교사관계 변인이었다. 이러한 결과를 기초로 본 연구는 청소년의 학교적응을 높이는 방법으로서 교사 친구 부모와의 관계를 긍정적으로 변화시키기 위한 실제적 방안을 제시하였다.

The purpose of this study is to develop the life scale of the middle aged homemakers. The life scale are composed of spouse relation 8 items, child education relation 7 items, home economy relation 4 items, homework relation 3 items, selfish health relation 6 items, parent relation 3 items, and interest and social activity relation 4 items. The reliability coefficient of the development scale was Cronbach'α =.83 and the correlations of each demesne was high. For the better future life in this study, the middle aged homemakers are needed the improvement of conjugal relations, the child education, the health, the interest, and the enlargement of social relations. This life scale can help to evaluate their middle age, and to the planning of energetic healthful future, and useful to understanding characteristic and the developmental task of middle aged homemakers.

XML 전자상거래 분야 뿐만 아니라. 모든 학술분야와 산업분야에서 사용하고 있는 만큼, 표준화된 문서를 다루는 필수적인 기능을 가지고 있다. 또한 XML 자료를 관계형 데이터베이스 자료로 만들어 SQL 언어를 사용하여 자료 검색도 필요하다. XML과 관계 데이터베이스 간의 변환을 위해선 두 자료간의 매핑 관계가 필요하다. 그래서 본 논문에서는 문서 자체에서 항상 통일된 형식으로 문서를 작성하게 하고 문서를 읽을 때마다 이런 통일성을 자동적으로 검사하게 하는 DTD(Document Type Definition)를 사용해서 XML과 데이터베이스 간의 매핑 관계를 연구하고, 그 결과 XML Data를 Realation Database table로 매핑하는 매핑 설계도를 연구하였다.

The objective of this research is to analyze how main social relation network of middle-aged women such as family, friends and neighbors, etc affects the preference for silver town. For this objective, structured questionnaires were distributed to 309 middle-aged women at the age of 40-59 years old living in Seoul and new cities of metropolitan area. Statistics such as ANOVA, Pearson Coefficient and Multiple Regression were adopted for statistical analysis. The main result of this research is as follows: First, housewives showed higher preference for silver town than people involved in other occupations. Second, though the relation of friends and neighbors among the social relation network of middle-aged women affected the preference for silver town, that of family did not affect significantly. The result of this research suggests that it is necessary to adopt policy considering the relation of friends and neighbors among the social relation network of middle-aged women so as to activate silver town.

When the complete denture is made, the record base for jaw relation is divided into temporary record base and permanent record base. However, The temporary record base include some disadvantages such as, the lackness of intimate contact between model and base, the lackness of retention during the jaw relation registration, When we obtained jaw relation the permanent record bases made from heat curing resin were utilized. We could get several advantages as follows : 1. The permanent record base provided intimate contact between the model and record base. 2. In fabricating occlusal rim on record base, the dimensional change of record base was little because the permanent record base was lesser influenced to thermal change of occlusal rim than the temporary record base. 3. At the stage of jaw relation, the retention of final denture could be early checked. 4. It could be able to get more accurate registration of jaw relation because all procedure were done on the same base during the jaw relation, artificial teeth arrangement, try-in, and final denture construction. 5. Although there was an inconvenience due to double curing procedure, the shrinkage rate in resin polimerization was relatively reduced so that more dimensional stability could be taken.
