This research sought to conduct art therapy to mild mentally retarded students in middle school to correct their maladjustment behavior and enhance their adaptability to the routine life. The specific objectives of the research are as follows. First, the research determines the effect of art therapy on the maladjustment behavior of mild mentally retarded students. Second, the research determines the effect on the change in maladjustment behavior of the mentally retarded students in the process of treatment by session. The conclusion of the research is as follows. First, when various art therapy programs were offered, the maladjustment behavior of less serious mentally retarded students lessened. Second, the students could not follow appropriately the researcher's instruction and befriend each other during the initial phase of the art therapy, but with sessions continuing, students increased their interaction with the researcher, and improved relations with their peers. Hence, art therapy programs are considered to be useful in improving the maladjustment behavior of mentally retarded children on the education field.

자궁경부 상피내병변에서 HPV와 p53 단백의 변화에 대한 면역조직화학적 소견

기근홍,황철기,신향미 조선대학교 부설 의학연구소 2000 The Medical Journal of Chosun University Vol.25 No.1

Background and Objectives : p53 is a tumor suppressor gene. Loss of function of the p53 tumor suppressor gene implicated in a wide variety of human tumors. Many mechanisms are involved in p53 dysfunction. One of the mechanisms is binding of oncogenic virus such as human papillomavirus (HPV). HPV infection are strongly linked to the development of cervical neoplasia including cervical intraepithelial neoplasia (CIN) of uterine cervix The purpose of this study is to investigate the relationship between aberrant p53 expression and presence of HPV DNA in CIN of the uterine cervix. Materials and Methods : In the present study, the author analyzed 35 cases of paraffin-embedded CIN, including 10 cases of grade 1, 10 cases of grade Ⅱ, and 15 cases of grade Ⅲ CIN by the immunohistochemistry and in situ hybridization. Results : Overall positive rate of HPV DNA type 16 and type 18 was 74.3% (26 cases) and 65,7% (23 cases), respectively. Nuclear accumulation of p53 was found in 22 cases (62.9%) of all CIN. In negative cases of HPV DNA type 16, the p53 was positive in 18 cases and negative in 8 cases. In positive cases of HPV DNA type 18, the p53 was positive in 16 cases and negative in 7 cases. In negative cases of HPV DNA type 16, the pS5 was positive in 6 cases and negative in 6cases. Conclusion : This results suggest that HPV infection may contribute to the DNA damage associated with the accumulation of aberrant p53 protein, and then closely relate to the progression of cervical neoplasms. But, alteration of p53 Protein levels and presence of HPY DNA was not an exclusive markers of cervical tumorigenesis.

신향근 順天大學校 1994 論文集 Vol.13 No.1

작용소행렬 노름(operator matrix norm)과 완전 유계사상(completely bounded map)이 작용소 공간(operator sapce)연구소에서는 중요한 역할을 한다. Z-J. Ruan 이 작용소 공간을 ??-행렬 노름 공간 (??-matricially normed space)으로 추상화한 후 바나흐 공간(Banach space)상의 많은 성질들이 작용소 공간에서도 유사한 형태로 얻어질수 있음이 연구되어지고 있다. 본 논문에서는 힐버트 공간 (column Hilbert space)의 텐서곱에 관한 몇가지 유사 성질을 조사하였다. □In contrast to Banach space theory operator matrix norms and completely bounded maps play a key role in the study of operator spaces, i.e.linear subspace of B(H) for some Hilbert space H.The abstract definition for operator space was given by Z-J.Ruan in [ 9 ].where he characterized the operator space as the norm closed subspace of bounded linear operators on a Hilbert space. Since then , it was investigated that many results in Banach spaces have parallel properties in operator spaces. In this paper we show some related results of the tensor product in column Hilbert space,.which are originated by Z-J.Ruan.

The main purpose of the surgical correction of dentofacial deformity is to improve esthetic appearance and masticatory functions. In this study, changes in intercondylar width (ICW) and condylar angulation that occurred following bilateral sagittal split osteotomy and mandibular setback were documented and examined using submentovertex radiography. Also, ICW and condylar angulation of patients group were compared with normal control group. Twenty normal adults and sixteen patients were involved in this study. The results were obtained as follows ; 1. Mean condylar angulation of normal control group (n=20) with normal TMJ function and normal occlusion were 15.96° on Left TMJ and 18.30° on Right TMJ. 2. Mean preoperative condylar angulation of patient group were 17.28° on Lt. TMJ and 18.97° on Rt. TMJ. There was no significant difference between the preoperative condylar angulation (n=16) and normal control group (n=20). 3. Mean postoperative condylar angulation of patient group were 17.88° on Lt. TMJ and 18.97° on Rt. TMJ. There was no significant difference between the pre-and postoperative condylar angulation(P>0.05). 4. Mean ICW of normal control group(n=20) was 107.35㎜ and mean ICW of patient group was 104.28㎜. There was no significant difference between preperative ICW and normal control group. 5. Mean postoperative ICW of patient group was 108.13㎜. There was no significant difference between the pre-and postoperative ICW.(P>0.05) 6. There were no significant differences between pre-and postoperative ICW and condylar angulation of male patients (n=6) and female patients (n=10) groups.

It is thought that the pleasant and interesting class would change students' learning attitude positively and increase learning effects. So we are trying to introduce the application of computers to the class to be used in various ways and to be effective in arousing the learning motivation of students. The purpose of this research is to look for the teaching method which can cause students' interest in learning and help students to have an affirmative attitude toward their learning. After carrying out both the presentation program using computer and the traditional, explanatory class alternately, we conducted a comparative analysis on the students' learning attitudes and examined the students' responses on the 'presentation' class. The result of the research was that the 'presentation' class was more affirmative in arousing the motivation of the students than the traditional, explanatory teaching method. We also came to the conclusion that the 'presentation' class was more affirmative in establishing a positive learning attitude than the traditional, explanatory class.

The purpose of this study was to present development plans and to draw up measures to specialize the College of Education (COE) as a teacher training institute after analyzing the problems with which COE in confronted. The plans and measures are primarily to aim attracting many students with better qualities and to assist them to have teaching jobs under the current system of Examination for Teacher Appointment. This study involved multiple data sources obtained from literature review questinnaire survey, and personal contact with the faculty of COE, Questions in the questionnaire were addressed to ask the faculty´s opinions on a curriculum, a school system in university, a practicum for teacher training, a middle and a high school attached to COE, establishing an in-service teacher training institute in COE, and other measures related to the specialization of COE. The findings of the study indicated that the following suggestions should be realized if COE is to be developed and specialized ; 1. A special selection procedure should be applied to attract students with high qualities, 2. Education for the teaching of subject matters should be reinforced and a new curriculum be developed to meet the needs of COE, 3. Appropriate measures should be devised to carry out substantial teacher training for student teachers, 4. A curriculum committe should be formed and asked to work for the management of the curriculum suitable for the specialization of COE, 5. A multi-major or a minor system should be introduced across the student´s specialization fields, 6. A department needed in COE can be established as a major area under the school system in university, 7. The establishment of a middle and a high school attached to COE should be proposed to the Ministry of Education, 8. An educational research center should be established to investigate into issue related to pro-service and in-service education continually, 9. An institute for in-service teacher training and a community education center should be established to render services to the local community, and 10. A second building of COE should be constructed to be equipped with sufficient educational facilities.
