Autogenous periosteal grafts are the attractive alternative to existing barrier membrane materials since they meet the reqiurements of an ideal material. But no histological data are available on the effectiveness of periosteal membranes in the treatment of periodontal defects. The purpose of this study was to evaluate effect of autogenous periosteal graft on periodontal regeneration histologically. Calss Ⅱ furcation defects were surgically created on the second, third and the fourth premolars bilaterally in the mandibles of six mongrel dogs. The experimental sites were divided into three groups according to the treatment modalities; control group - surgical debridement only : Group Ⅰ- autogenous periosteal membrane placement after surgical debridement; Group Ⅱ- autogenous periosteal membrane placement after surgical debridement and bone grafting. The animals were sacrificed at 2, 4 and 12 weeks after periodontal surgery and the decalcified and undecalcified specimens were prepared for histological and histometrical analysis. Clinically all treated groups healed without significant problems. Under light microscope, at 2 weeks, control group showed significant apical epithelial migration and bone remodelling only below the notch area. But for the groupⅠ, Ⅱ with autogenous periosteal graft, less apical migration of epithelium appeared and large amount of osteoid tissue was showen above the notch area. Grafted periosteal membrane was indiscernable at 4 weeks, so periosteal membrane might be organized to surrounding tissues. Histometrically, at 4 and 12 weeks, all the test and control groups didn't show significant change of epithelial zone but new attachment level tended to be gained in the test groups than control group. These results suggest that autogenous periosteal grafts could be a good alternative for guided tissue regeneration.

본 실험은 삼차신경 자극으로 발생되는 체성 감각 유발 전위에 대한 국소마취제의 효과를 관찰하였다. 나트륨 통로차단을 통하여 약리작용을 나타내는 것으로 알려져 있는 리도카인를 뇌 피질에 국소 투여한 후 삼차신경의 체성 감각유발 전위의 강도및 지연시간을 측정하였다. 케타민으로 마취된 흰쥐의 대측성 구레나룻 자극후 뇌의 체성 감각영역으로부터 기록되는 유발전위를 분석한 결과, 리도카인을 뇌 피질에 국소 투여시 유발전위의 강도 및 지연시간의 감소가 나타났으며, 필드 전위의 형태는 이상성(양극성 및 음극성) 혹은 삼상성(양극성, 음극성 및 양극성)의 파형으로 나타났다. 필드 전위의 발생 부위는 뇌 피질의 중대뇌동맥의 상행지 상방영역이었다. 본 실험에서 나타난 초기 전위변동은 피질판 상층에 존재하는 신경세포의 탈분극 과정에 의하여 생성되고 후기 전위 변동은 피질판 상층에 존재하는 신경세포의 탈분극 과정에 의하여 생성되고 후기의 전위 변동은 동일 영역의 하층 신경세포에서 과분극 혹은 재분극이 발생한 결과라고 유추된다. 따라서 삼차신경계의 체성 감각 영역에서는 피질 상층및 하층의 과립성 피라미드 세포의 순차적인 활성화에 의하여 기본적인 신경 회로망이 형성되어 있으며 생리적 자극으로 유발되는 필드 전위는 이러한 신경망를 통하여 발생될 것으로 사료된다.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

사회복지 현장의 수퍼비젼 방식 연구

양정남,최은정,정현주 동신대학교 2006 論文集 Vol.16 No.-

The purpose of supervision is to provide clients with the best service. In essence, supervision is a systematic exercise which is realized on the basis of communication and decision-making between a supervisor and a supervisee. The process of supervision is accomplished through good communication. Thus, in order for the supervision to function well in a social welfare agency, not only the contents of the supervision but the way of forming the supervision is seriously taken into account. Even though the supervision content is of good quality and the speciality of the supervisor ensured, the primary purpose and object of the supervision can hardly be achieved unless the communication between the supervisor and the supervisee is effective. For this reason, this study looks into the issue of the process of supervision deliverance and communication, and suggests an application of Shared Decision making, an educational theory, to the supervision for a better outcome. In the 1980s, a startling vision of education's future began appearing in reform proposals: school run by committees of teacher, without an administrator in sight. Since then, SDM has become a significant part of school-reform. SDM is the process of making educational decisions in a collaborative manner at the school level. The purpose of SDM is to improve school effectiveness and student learning by increasing staff commitment and ensuring that schools are more responsive to the needs of their students and community. SDM as a social work supervision model involves six main safeguards and benefits, which are as follows. ① Peer review of professional decisions ② It ensures that no client's liberty is affected(eg coming into care) without scrutiny of that decision. ③ It ensures clients are not left in unacceptable risk situations on the basis of a single individual's assessment or action. ④ It ensures that professionals are not put into a position where situations may exceed their knowledge, skills or experience or where they are having to manage very stressful and emotional situations. ⑤ Protection of the Agency: SDM has the responsibility to safeguard and ensures the importance of both supervisor and agencies role. ⑥ It encourages openness and collective responsibility.

Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

MAGFET의 드레인과 바이어스 조건에 따른 감도특성

임현주,남태철 嶺南大學校 工業技術硏究所 1998 工業技術硏究所論文集 Vol.26 No.1

We have fabricated and analyzed a magnetically field-sensitive transistor(MAGFET) with two and three splitted-drains The current difference between the split-drains show a good proportionality to the magnetic field intensity in both types. The absolute sensitity of the MAGFET shows the characteristics like the Id-Vd curve of a MOSFET. But its relative sensitivity is almostly independent on both Vd and Vg and has constant values. A MAGFET with three drains shows higher relative sensitivity than one with two drains.

조현영,정남주 호남대학교 2008 학술논문집 Vol.29 No.2

The purpose of this study was to investigate the kinematical analysis on the running motion of elementary students. The subject of this study was 12 healthy elementary students. A scholastic year were divided into 2 group : high group[6 grade], middle group[3 grade]. The following findings are obtained: It's appear that time ratio of the stance and swing in running motion about high group was 56% vs 44%, and this result was effected to wide step and stride length. Also, it's appear that displacement of center of gravity about high group was larger than middle group, and this result was effected to the horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was larger than middle group. And then this result was effected to the lower extremity movement. It's appear that time ratio of the stance and swing in running motion about middle group was 61% vs 39%, and this result was positively effected to narrow step and stride length. Also, it's appear that displacement of center of gravity about middle group was less than high group, and this result was effected to the low horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was less than high group. And then this result was negatively effected to the lower extremity movement.

The purpose of this study was to investigate the kinematical and ground reaction force variables according to the trunk lean[type A : 0~4deg., type B : 6~12deg.) during the stair ascent. For thi experiment, the stair structure was made and AMTI force plate was installed on the second and third stepping. Each motion was videotaped and digitalized with five video cameras to calculated the kinematical variables, and at the same time collected the ground reaction force. As a result, the following findings were obtained: 1. It was found that gait cycle of the type A was longer than type B, but ratio of the stance and swing to the gait cycle was similar to each other. Also it was found that stair ascent of the type A was more effective than that type B in the lower extremity motion. 2. It was found that stair ascent of the type A in the vertical and antero-posterior ground reaction force variables was more effective than that type B in that ascending the body weight.
