본 연구의 목적은 집단미술치료프로그램이 결손가정아동의 자아존중감과 사회성, 일반정신건강에 미치는 효과를 알아보는데 있다. 이를 위하여 경기도 수원시에 소재한 I초등학교 3, 4학년 10명을 연구대상으로 선정하였다. 이 집단에 2006년 9월부터 12월 2일까지 개별집단과 협동집단으로 주1회 수요일 60분에서 90분 정도로 총 12회기 집단미술치료 프로그램을 실시하였다. 실험 처치 후의 효과를 검증하기 위하여 자아존중감, 사회성 검사 그리고 일반 정신 건강 상태 검사를 사전-사후로 나누어 실시하여 측정 자료를 수집하였으며, 사전-사후 점수의 총점과 평균차를 분석하였다. 또한 프로그램 실시의 효과를 알아보기 위해 질적 방법으로 그림투사검사(K-HTP, 동적가족화, 학교그림)의 사전, 사후 검사를 통하여 변화를 분석하였다. 이러한 연구 결과에 의거하여 집단미술치료프로그램이 결손가정 아동의 자아존중감 향상과 사회성 증진 그리고 일반정신건강상태 향상에 효과가 있다는 결론을 얻을 수 있었다. (임상미술치료학연구 2007;2(2):109-128) The purpose of this study is to show the effect of the group art therapy program on the self-esteem, the sociality and the general mentality of a child from a single-parent or parentless family. To conduct this study, I selected 10 students from the third and fourth graders of ‘I’ elementary school in Suwon and carried out 12 times of art therapy programs from Sep. to Dec. in 2006;once a week and for 60 to 90 minutes each time. To prove the effect of the art therapy program through this experiment, I conducted a test in the self-esteem, the sociality and the general mentality two times before and after the art therapy and analyzed the difference between the sum and averages of the first test scores and those of the second test scores. Followings are the results of this study. First, the group art therapy program effectively increased the self-esteem of the children from single-parent or parentless families. Therefore, the program should be constantly conducted for those children. Next, the program effectively improved the sociality of those children. So, it can be a sociality enhancing program for single-parent or parentless children. Finally, the general mentality of those children who had been in this program improved much. It means that this program has beneficial influence on the mentality of the children. Based on the results of this study, I could get the conclusion that the group art therapy program is effective in increasing the self-esteem, the sociality and the general mentality of the single-parent or parentless children.

Purpose: The objective of this study was to investigate the influence of hospital nurses’ self-leadership, communication skill, and self-esteem on the quality of nursing service. Methods: The participants, 230 nurses working at a general hospital in Seoul, completed a cross-sectional descriptive questionnaire survey between January 17 and 28, 2014. The collected data were analyzed using the SPSS 19.0 program for descriptive statistics, t-test, one way & two way ANOVA, correlation, and multiple regression analysis. Results: Nurses" self-esteem and communication skill had significant main effects on self-leadership and the quality of nursing service, but the interaction effect of the two independent variables was not significant. Variables that significantly influenced the quality of nursing service were self-leadership, communication skill, self-esteem, and career longevity. The explanatory power of these variables for the quality of nursing service was 54.4%. Conclusion: Findings indicate a need for education programs for nurses which are designed to promote communication skill and enhance self-esteem and self-leadership skills which will in turn enhance the quality of nursing service.

교육시설 측면에서 본 제7차 교육과정 도입실태에 관한 연구

송희정(Song, Hee-Jung),박준수(Park, Joon-Soo) 대한건축학회 2016 대한건축학회논문집 Vol.32 No.5

The 7th Educational Program was introduced and implemented with the goal of transitioning into student-centered education system. However, the new curriculum failed to settle properly due to lack of accurate understanding about the new curriculum system and implementation refusal of unilateral radical introduction. The 7th Educational Program maintained the philosophy and system and since been amended 5 times. The direction of revision of the curriculum improved the problems of application while gradually alleviating the existing policy. And the introduction of the curriculum was separated into categories, to allow for different acceptance decisions regarding each category. Accordingly, by accurately verifying the conditions after the 7th curriculum was introduced, the goal of this study is in comprehending the actual state and problems, through current possession of facility for each of the introduction categories and method of operation. The research analysis result of current possession of facility for each of the introduction categories and method of operation are as follows. First, with the exception of a few schools, the subject schools possess facilities of scale that makes the introduction of curriculum possible. Second, it was evident that the space for teachers to conduct research, work, and rest, were comparatively insufficient, when the student-centered curriculum was implemented. Third, partial implementation in which only a part of the curriculum is implemented and non-implementation in which the curriculum is rejected, were judged to be ambiguous in the level of curriculum implementation and had no major differences. The results above are expected to assist in seeking for appropriate development measures for our country’s future curriculum and in setting the direction.

The purpose of this study is to find out how successful The 7th Educational Program is in reforming the middle school in terms of the school facilities. Through every steps of the construction process, carefully analyzed the design documents of the selected school buildings and checked the compliance level of the design standards provided for The 7th Educational Program. After that, thorough survey and interviews with the person in charge were made for some of those schools. The result of the study shows that the standards for The Program was quite fulfilled in preliminary design stage but the level of compliance became lower and lower as the construction process went by in terms of space programming and room requirements especially in those areas like home base and spacial study classrooms that are the core ingredients for The Program. According to the result of this research, we cannot help but realize that not only the facility itself but also the operation of the institution to adopt The 7th Educational Program might not work properly as much as we expected up to this moment.

아밀로이드소체는 정상적인 노화과정이나 신경변성질환에서 뇌에 축적되는 당단백질 포함물이다. 아밀로이드소체의 세포 유래가 신경세포나 신경아교세포로 제시되고 있지만, 아밀로이드소체 형성에 대한 기전은 잘 알려져 있지 않다. 본 연구의 목적은 사람 뇌의 아밀로이드소체 유래를 확인하는데 있으며, 이를 위에 사람뇌에서 H-E 염색, PAS 염색, 면역조직화학염색을 시행하였으며 흰쥐를 이용한 실험적 아밀로이드소체 모델도 만들었다. 아밀로이드소체는 가쪽뇌실벽 백색질의 깊은층보다 뇌척수액과 접하는 얕은층에서 관찰되었으며 가끔 혈관 주변에서도 관찰되었다. 많은 아밀로이드소체가 있는 나이든 사람 뇌에서는 맥락얼기가 파괴되어 있었으며 psammoma체가 관찰되었다. 아밀로이드소체 핵은 주로 무정형의 PAS 양성물질로 구성되어 있었으며, GFAP 양성인 별아교세포 돌기가 아밀로이드소체 표면에 부착되어 있었다. 치아돌기 등의 회백질에는 MAP2가 약하게 관찰되었다. Cysteamine에 의해 유도된 아밀로이드소체 동물모델에서는 PAS 양성 아밀로이드소체가 가쪽뇌실에서 뇌척수액과 접하는 해마의 경계부위에서 관찰되었다. 본 연구 결과에서 나이든 사람의 뇌에서 아밀로이드소체의 주요 세포성분은 별아교세포이며, 아밀로이드소체 핵 형성은 뇌척수액과 관련되어 있는 것을 알 수 있었다. Corpora amylacea(CA) are glycoproteinaceous inclusions that accumulate in the human brain during normal aging and neurodegenerative diseases. Although it has been suggested that the cellular sources of CA are neuronal or glial, the mechanisms underlying CA formation remain controversial. The aim of this study was to identify the source of CA in the human brain. Sample of the human brain tissues were obtained from the cadavers. H-E stain, periodic acid-Schiff(PAS) stain, and immunohistochemistry were performed in the brain tissues, Experimental induction of CA was also performed in rats. CA have been found in large numbers in the superficial, rather than in the deep, layer of the white matter in the lateral ventricle that is in contact with the cerebrospinal fluid(CSF) and sometimes near the blood vessels. Destroyed choroid plexi with psammoma bodies have been observed in the lateral ventricle of aged brains containing substantial numbers of CA. The cores of CA were mainly composed of amorphous PAS-positive materials, and glial fibrillary acidic protein-positive astrocytic processes were attached to the surface of the CA. Weak MAP2 was detected on a few CA in the gray matter such as dentate gyrus. PAS-positive CA were located on the border of the hippocampus contacting the CSF in the lateral ventricle in the cysteamine-induced CA animal model. Taken together, main cellular source of CA is astrocytes and CA core formation may be associated with CSF in the aged human brain.

본 연구는 전신마취 하에 복강경을 이용한 담낭절제술을 받은 환자의 수술 후 회복과정에서 근이완 길항제 종류에 따라 수술 후 호흡근육 활성도, 통증, 회복지수 및 회복실 체류시간의 차이가 있는지 확인하고자 실시하였다. 전신마취 하에 복강경 담낭절제술을 받는 성인 환자를 대상으로 sugammadex(1군)와 pyridostigmine(2군) 투여군을 각각 30명씩을 대상으로 조사를 하였으며 분석결과 호흡근육 활성도 평가는 수술 후 회복실 입실직후 1군 3.80±1.75점, 2군 2.83±1.32점(p<0.031)이었고, 입실 10분 후에도 1군 5.33±1.03점, 2군 4.30±1.44점(p<0.003)으로 유의한 차이가 있었고 1군이 2군에 비해 호흡근육 활성도가 높았다(집단*시점, p<0.049). 수술 후 통증의 정도는 1군과 2군의 두 그룹 간에 유의한 차이는 없었으나(p<0.567), 시점에 따른 차이는 있었으며(p<0.001), 교호작용은 없었다. 두 군간의 회복지수는 입실 시(12.13±0.90 vs 12.00±0.64, p<0.932)점, 퇴실 시(14.10±0.71 vs 13.87±0.43, p<0.323)점으로 두 군간의 유의한 차이가 없었다. 두 군의 회복실 체류시간(31.23min±11.19 vs 40.97min±12.54, p<0.002)으로 1군이 2군보다 회복실 체류 시간이 더 짧았다. 새로운 근이완 길항제의 개발이 회복 간호에 영향을 주는 요인을 파악하고 약제에 대한 효과와 원리 및 사용방법에 대한 간호 교육을 제언하는 바이다. The objective of this study was to identify the effects of sugammadex and pyridostigmine in the postoperative recovery including respiratory muscle activity, pain score, PAR score and postoprative period in the recovery room after laparoscopic cholecystectomy. Data were retrospectively collected from adult patients under general anesthesia in K hospital: 30 patients each group assigned to receive sugammadex (group 1) and pyridostigmine (group 2). There were significant differences in respiratory muscle activity score in two groups immediately after admission to the recovery room (3.80 ± 1.75 vs 2.83 ± 1.32, p<0.031) and at 10 minutes after admission to the recovery room (5.33 ± 1.03 vs 4.30 ± 1.44 points, p<0.003). Group 1 showed higher than group 2 (group*time p<0.049). Although there was no significant difference in overall postoperative pain between the groups (p<0.567). There were no differences in the recovery index. PACU stay was significantly shorter in group 1 than 2 (31.23 min ±11.19 vs 40.97 min ±12.54, p<0.002).

Cerebrolysin Attenuates Astrocyte Activation Following Repetitive Mild Traumatic Brain Injury

만성외상성뇌병증(Chronic traumatic encephalopathy, CTE)은 운동선수와 매우 밀접하게 관련되어 있으며 장기간에 걸쳐 반복적인 외상성뇌손상(traumatic brain injury, TBI)로 인한 퇴행성뇌질환이다. 신경영양인자(neurotrophic factor)는 여러 종류가 알려져 있으며 이들은 뇌와 척수의 물리적 손상시에 신경보호효과가 있다. 따라서, 신경영양인자의 혼합물인 cebrolysin을 이용하여 CTE질환에 가장 적합하다고 여겨지는 repetitive mild TBI (rmTBI) 모델에서 cerebrolysin의 신경보호효과를 알아보고자 하였다. 실험군은 5군(groups 1 and 2: rmTBI for 4 weeks following cerebrolysin injection for 4 weeks; groups 3 and 4: rmTBI for 8 weeks with or without cerebrolysin injection for 4 weeks; group 5: control)으로 나누어 진행하였다. CTE의 가장 대표적 표시인자인 tau 단백질의 인산화를 조직학적으로 조사한 결과, 대뇌겉질과 해마내 CA3 영역에서 phospho-tau단백질의 발현이 증가되었으며 cerebrolysin (10 μl of 1 mg/ml)를 미정맥으로 투여시 p-tau발현이 감소되었다. CTE의 병인으로 알려진 별아교세포와 미세아교세포의 활성을 각각의 표시인인 GFAP, iba-1을 이용하여 면역조직화학염색을 시행 하였다. 별아교세포의 활성은 rmTBI에 의하여 증가하였으며 cerebrolysin에 의해 회복되었으나 미세아교세포의 활성은 관찰되지 않았다. 또한 rmTBI모델에서 체내 탐식세포(macrophage)의 뇌내유입유무를 관찰하고자 CD45 염색을 시행하였으나 유의한 차이를 관찰하지 못하였다. 이상의 결과를 종합하면, cerebrolysin이 rmTBI에 의한 tau단백질의 인산화 및 별아교세포의 활성을 조절하는 것으로 사료된다. 따라서 cerebrolysin이 CTE 환자에 대한 치료 약물의 후보가 될 수 있음을 시사한다. Chronic traumatic encephalopathy (CTE), which is common in athletes, is a progressive neurodegenerative disease and a long-term consequence of repetitive closed head injuries. CTE is regarded as a chronic brain syndrome due to the effects of repetitive traumatic brain injury (TBI). Because neurotrophic factors are neuroprotective in models of brain and spinal cord injuries, we examined the effects of cerebrolysin, a mixture of various neurotrophic factors, on brain pathology in a mouse model of repetitive mild TBI (rmTBI), which is a good model of CTE. Five groups were created and treated as follows: groups 1 and 2: rmTBI for 4 weeks following cerebrolysin injection for 4 weeks; groups 3 and 4: rmTBI for 8 weeks with or without cerebrolysin injection for 4 weeks; group 5: control. We found that p-tau expression was increased in the pyramidal layer of the cortex and hippocampus, particularly the CA3 region, but not in the CA1 region and the dentate gyrus (DG). Intra-tail vein administration of cerebrolysin (10 ml of 1 mg/ml) after/during rmTBI treatment reduced p-tau expression in both the cortex and hippocampus. Histological analysis revealed mild astrocyte activation (increased expression of glial fibrillary acidic protein (GFAP)) but not microglia activation (ionized calcium binding adaptor molecule 1 (iba-1) expression) and peripheral macrophage infiltration (CD45). Additionally, administration of cerebrolysin after rmTBI resulted in reduced astrocyte activation. These observations in rmTBI demonstrated that cerebrolysin treatment reduces phosphorylation of tau and astrocyte activation, attenuates brain pathology, and mitigates function deficits in TBI. Taken together, our observations suggest that cerebrolysin has potential therapeutic value in CTE.
