The basic structure of the primary crowns usually resemble their succeeding permanent teeth. However, maxillary second primary molars resemble ipsilateral first permanent molars. Accordingly in this study, odontometric data of the two teeth was obtained, then analyzed to verify the morphological relationship and sex difference between the two teeth. Dental study casts were examined for their mesiodistal and buccolingual width of the crowns, diameter of each cusps, and intercuspal distances. Photographs of the crowns were taken to measure the angles between each cusp tip. The results are as follows : 1. In boys, PrI, PaI, DBC angle, and MBC angle did not show any statistically significant difference between the two teeth(p>0.05), and moderate level of correlations were observed. 2. In girls, crown index, DBC angle, and MBC angle of the two teeth did not show any statistically significant difference(p>0.05), and moderate level of correlations were recognized. 3. Measurements that did not show statistically significant difference between the two teeth in both boys and girls were DBC angle and MBC angle(p>0.05). In DLC angle, however, statistically significant difference was observed(p<0.01). 4. Most of the measurements showed sex differences, except DBC angle, which did not show any sex difference in both teeth(p>0.05). 유치 치관의 기본적인 구조는 대개 계승 영구치를 닮는다. 그러나 제2유구치는 계승 영구치인 제2소구치보다 오히려 제1대 구치와 더 유사한 경향이 있다. 이에 본 연구는 한국인에서 상악 제2유구치와 제1대구치의 치아계측학적 자료(odontometric data)를 얻어 두 치아의 형태와 크기 사이의 연관성을 살펴보고, 나아가 남녀간의 차이점 유무를 고찰해 보고자 하였다. 남아 150명, 여아 150명 총 300명의 모형을 이용하여 상악 제2유구치와 상악 제1대구치의 근원심 치관 폭경, 협설측 치관 폭경, 각 교두의 직경, 교두정간 거리를 계측하였고, 치관의 교합면 사진을 촬영하여 각 교두정 사이의 각도를 측정하여 다음과 같은 결과를 얻었다. 1. 남아에서 Protocone index, Paraconeindex, Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 상악 제1대 구치와 제2유구치 사이에 통계적 유의차가 관찰되지 않았고(p>0.05), 중등도의 상관관계가 확인되었다. 2. 여아에서 crown index, Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 상악 제1대구치와 제2유구치 사 이에 통계적 유의차가 관찰되지 않았고(p>0.05), 중등도의 상관관계가 확인되었다. 3. 남, 여 모두에서 Distobuccal cusp(DBC)각, Mesiobuccal cusp(MBC)각은 두 치아 사이에 유의할만한 차이를 보이 지 않았고(p>0.05), Distolingual cusp(DLC)각에서는 통계적 유의차가 관찰되었다(p<0.01). 4. 대부분의 계측치에서 남녀 차이를 나타냈지만, Distobuccal cusp (DBC)각은 상악 제1대구치와 제2유구치 모두에서 남녀 차이를 보이지 않았다(p>0.05).

The purpose of this study was to investigate the rescarch pattern and trends of Tae Kwon Do researches. Hundred ten papers were analysised for this purpose and the analysis were devided two categories. The first category was analysis of subject in Tae Kwon Do research. The second category was analysis of object in Tae Kwon Do research. From the analysis, result were made as follows; 1. Analysis of subject in Tae Kwon Do research. The researches which treat physiological factor were 26.4%, the researches which treat techniques for compitition were 25.5%, and the researches which treat psycological factors were 11.8%. 2. Analysis of object in Tae Kwon Do research. The researches which object compitition were 77.3%, and it contains kicking, physical fitness, point, athlete, division, weight, structure of technique, injury, judge, rules. The researches which object displine were 10% and reality of Tae Kwon Do were only 9%

Purpose: The objective of this study was to verify the effects of the Singing program for psychiatric patients on their self-esteem and interpersonal relationship, and to provide data for the nursing intervention that is necessary for making their life better. Method: The subjects were 10 in-patients with psychotic disorders at C university hospital in Seoul, from july 3 to September 18 im 2005, and the methodology was one group pre experimental- post experimantal design. The instrument for the measurement of self-esteem is Rosenberg Self-Esteem Scale(1973), which was translated by Chun Byung Jae(1974) and the measurement of interpersoral relationship is Schleim & Guerney Relationship Change Scale(1971) which was translated by Mun Seok Mo(1980) and revised by Chun Seok Gyun(1994). SPSS program was used for the analysis of the collected data, which were analyzed by the paired t-test and one-way ANOVA. Result: Singing therapy had an effect on improvement of the self-esteem, and seemed to be more effective as the frequency of the program increased. Singing therapy had an effect on improvement of the interpersonal relatinship, and seemed to ne more effecive as the frequency of the program increased. Comclusion: Singing therapy is found out to be effective program affecting the improvement of both the self-esteem and interpersonal relationship of the psychiatric patients. Therefore the nurses can use the Singing therapy as the nursing intervention for imtrovement of the self-esteem and interpersonal relationship of the psychiatric patients in clinical practice.

An attempt of indicating al perspective for the systematic arrangement of studies on sports and politics was made examining the contents and method of preceding studies conies concerned. Main results are as follow; 1. The concrete domains of the study on sports and politics are classified into such five categories as sports policy sports and political ideology, political functions of sports, sports and social regime, and sports international relations. After indicating the problems to be solved in terms of the systematic arrangement of the studies in each category, they are mutually related and a guideline for the systematization of studies on sports and politics is presented. 2. Politics can basically be understood as policy which has a certain logical relation with public interests and power, for the analysis of mutual relation between sports and politics standing on the basic of policy it is inevitable to clarify the meaning of in fluence relation and function Especially logical improvement of the method of functional analysis is indispensable.

Recycling of thermoplastic polyolefins bumper has been carried out by stirring a coarse-crushed plastic material inside a chemical reactor using dichloromethane(MC) to release the paint film and drying the solvent. Chemical method adversely affects the physical properties or surface quality of the final product. It was found that wettability and surface tension of these polymers did not influence coating properties significantly. The diffusion coefficient of MC in PP/EPR blend has been monitored using an attenuated total reflection FT-IR. The test also demonstrated both the accuracy and quickness of FT-IR ATR experiment for measuring the diffusion coefficient of chemical recycling system Crystallinity and fractional free volume were very sensitive to the diffusion rates of small molecules in polymers as well as to the composition in recycled PP/EPR blends. It was suggested that concentration of the PP/EPR resins obtained from recycling process must be lower than 40wt percent in compounding.

본 논문에서는 자연스럽고 사용하기 쉬운 각 개인의 음성을 이용하여 신원을 확인 할 수 있는 화자 검증 시스템을 구현하였다. 본 연구에서 구현한 시스템은 상대적인 대수 에너지만을 사용하여 개략적인 끝점 검출을 실행하였고, 검출된 음성부분에 대하여 몇 가지 특징 파라메터에 대한 검증율 실험의 결과를 바탕으로 특징 파라메터로는 필터 뱅크 계수를 사용하였다. 또한 자신이 등록한 음성 패스워드로 각각 개인의 코드북을 따로 구성하는 방법을 사용하여 화자 검증율을 높였다. 벡터양자화에 대응하여 동작하는 상부 인식기로는 소규모 고립단어 인식에 적합한 동적 시간 정합법을 채택하였다. 본 논문에서는 효과적인 화자 검증 시스템을 구현하기 위한 특징 파라메터 및 코드북 구성에 따른 상대적인 검증율을 실험을 통하여 측정하여, 음성을 등록한 사람에 대해 각각의 코드북을 생성하여 화자 검증 시스템을 구현하였다. 향후 연구과제로 본 시스템은 잡음에 대해서 고려하지 않았지 때문에 잡음 환경에서도 사용자의 실제 음성을 이용하여 화자 검증 할 수 있도록 개선이 있어야 할 것이며, 전자상거래 및 정보보안에서의 전자 서명과 같이 음성을 이용하여 신원을 확인하는 기타 응용분야에 대한 연구가 필요하다.
