In physics education, the research on students' conceptions has developed in the discussion on the nature and the difficulty of conceptual change. Recently, mental models have been a theoretical background in concrete arguments on "how students' conceptions are constructed or created." Mental models that integrate information in the presented problem and individual knowledge in their long-term memory have important information about not only expressed ideas but also in the thinking process behind the expressed ideas. The purpose of this study is to investigate the forming process and the characteristics of high school student's mental models about circular motion, and how they were changed by instruction. We used the think-aloud method based on the instrument for identifying student's mental models about circular motion, pretest of physics concept, mind map and interview for investigating student's characteristics. The results of the study showed that instructions based on the mental model theory facilitated scientific expressed model, but several factors that affected forming mental models like epistemological belief didn't change scientifically after 3 lessons.

This study is conducted to analyse the process and the pattern of motivation for musical expression in clinical music therapy for the adults in the mental health center. The participant were 8 adults purposive sampling who had more than one year music therapy experience in the mental health center and their age ranged from 27 to 53. A major category derived and analysed from the grounded theory method by Strauss and Corbin. The qualitative analysis indicated that motivation for musical expression in music therapy, which was the central phenomenon in this study, was determined by the music therapist and songs used in the sessions. The central phenomenon was caused by the therapist's friendly attitude, high musical capacity, the familarity of the selected songs and the significancy of the lyrics of selected songs. The levels of reliability about the therapist's personality and musical ability as a professional music therapist and the positive arousal of the songs used in sessions affected as the contextual condition. Spontaneous musical expression in music therapy brought the escape from reality, release of stress and sharing by the intervening condition 'empathy' and this resulted in mood regulation, the instillation of hope and group cohesion. It has been found that there were three types of motivation in music therapy: intrinsic motivation, relationship dependent extrinsic motivation and evasive motivation.

Objectives : Neurological soft signs have been regarded as endophenotypes associated with the genetic basis of schizophrenia. This study was to investigate the intra-familial correlations of the neurological soft signs according to their genetic loading. Methods : Schizophrenic patients(N=14) were included, who had one parent with a family history of schizophrenia and the other without it. Genetic loading was determined by the patient's family history of schizophrenia using the Family Interview for Genetic Studies(FIGS). These parents were subdivided into two groups. The first group was designated as 'presumed carriers'(N=9) of genetic loading, who had one or more schizophreic firstor second-degree relatives. The second group was designated as 'presumed non-carriers'(N=11) of genetic loading, who had no schizophrenic first- or second-degree relatives. Normal controls(N=12) consisted of people without schizophrenic relatives. NSS were evaluated using the Neurological Evaluation Scale-Korean Version (NES-K), and the intra-familial correlations of NSS were tested using the Intra-Class Coefficients(ICC) method. Results : The scores of Motor Coordination subdimension of NES-K were significantly correlated between the patients and their presumed carriers(ICC=.804, p=.016), but not significantly correlated between the patients and their presumed noncarriers. In other subdimensions of NES-K, no significant correlation were found between the patients and their parents regardless of the genetic loading. But, there were no statistically significant differences in the scores of Motor Coordination subdimension of NES-K between the patients and controls. Conclusion : This study did not prove that the neurological soft signs might be an endophenotype of schizophrenia that cosegregate with the genetic loading. The future study using more subjects than this would be needed.

도파민 D 수용체 및 5-HT 수용체 차단기전을 지닌 새로운 항정신분열증 약물인 risperidone은 활성형 대사물로 9-OH risperidone을 체내에서 생성하는 바, 이 대사과정의 유전적 다형성의 여부 즉 hydroxylation 과정에 CYPIID6의 관여 여부를 검토코자 하였다. Metoprolol 100 mg 경구투여로 CYPIID6의 대사능의 표현형을 결정한 12명의 정상 피험자(11명: extensive metabolizer, 1명: poor metabolizer)를 대상으로 하였으며, 피험자는 risperidone 1 또는 2 mg 경구투여후 혈중 risperidone 및 9-OH risperidone 농도를 경시적으로 radioimmunoassay법으로 측정하였다. 이들 피험자중 6명의 extensive metabolizer는 quinidine 600 mg/day의 용량 투여로 CYPIID6의 활성도를 완전 억제시킨 후 risperidone 1 mg 경구투여에 따른 약동학적 성상을 재검토하여 risperidone hydroxylation에 CYPIID6의 관여 여부를 검토하였다. 1) 1명의 poor metabolizer는 extensive metabolizer에 비해 현저히 긴 risperidone 반감기를 보였다. 2) 12명의 피험자에서 관찰된 metoprolol metabolic ratio는 risperidone 혈장 반감기 및 log(risperidone AUC/9-OH-risperidone AUC)와 유의한 상관성을 나타내었다. 3) Quinidine 투여는 risperidone의 반감기의 유의한 증가와 9OH risperidone AUC의 현저한 감소를 보였으나, 9-hydroxylation 대사과정이 완전히 억제되지는 않았다.

In performance art, actors on the stage play an important role. The purpose of performance art is not in producing expression of superficial or trite pleasure, but in presenting a source of philosophical catharsis regarding essence of a human life. It is actors' responsibility to bring such expression onto the stage. Performance art not only involves technical skills but should be a cultural expression to represent tradition, spirituality and identity of a nation. In Korea, performance art tends to follow Western methods of expression. It is desirable to set a future direction to further develop methodology of expression in performance art. As part of such effort, the research examines how the rhythm of traditional Korean dance and dimension of time and space in performance art are effectively visualized in their relation to "stage direction." The research illustrates characteristics and concepts of Korean dances in terms of inhalation in deliberate hypogastric breathing ("danjeon') and rhythms of exhalation (gutgeori, jajinmori, huimori). Also, the research aims to enhance dramatic effect on the stage, which is distinguished from presentation of ordinary actions, by emphasizing dimension of time and space in visualizing expression.

As a makeup technique for a baby-faced image, there will be a difference in perception of the expression technique of baby-faced makeup according to general matters.' Two hypotheses were supported: 'There will be a difference in perception of the expression technique of baby face makeup depending on the general characteristics', and the makeup technique for creating a baby face image is an important function for both men and women, as well as appearance. As a 'physical resource' for social activities, it was confirmed that there is an improvement in the efficiency of the body and mind and an outstanding improvement in mental ability in daily life. Through the results of the study on 'expression of baby face image makeup', awareness and interest in baby face images are high, but research on the production of baby face images is needed. The need for facial expression elements for baby face makeup is expected to be used as basic data for developing baby face images, and this study focuses on external face management for baby face images and baby face makeup.
