This study presents seven patients with hypothalamic hamartomas diagnosed on the basis of MRI. Histological confirmation was performed in one patient who underwent surgery. Four patients presented with epilepsy, including gelastic seizures. Other symptoms were behavior abnormalities in 3 patients and precocious puberty in 4 patients. We classify hypothalamic hamartomas into four subgroups according to MRI finding : Types Ⅰa lesions were less than 10㎜ in diameter and pedunculaedly attached to tuber cinereum of hypothalamus without hypothalamic displacement. Type Ⅰb lesions less than 10㎜ and mamillary body. Type Ⅱa lesions were more than 10㎜ in diameter and sessilely attached to hypothalamus with slight hypothalmic displacement and Type Ⅱb lesions more than 10㎜ and with marked displacement of hypothalamus. We could achieve good result with surgical resection in one patient with Type Ⅱb hamartoma associated with gelastic seizure that was unresponsive to medical treatment. We performed gamma knife ragiosurgery in three patients with gelastic seizure(2 patients with Type Ⅱa and 1 patient with Type Ⅱb) and three patients with precocious puberty(2 patients with Type Ⅰa and 1 patient with Type Ⅰb). The authors propose direct surgery as a treatment for this progressive syndrome and gamma knife radiosurgery as alternative treatment for high risk patients.

특수학교(급)고등부 졸업생의 진로실태 및 진로 지원체제 구축방안 : Future Directions and Practices for Developing a Comprehensive Career Support System in Special Education School

정희섭,김현진,김형일,정동영,정인숙 국립특수교육원 2005 연구보고서 Vol.- No.11

이 연구는 장애인 삶의 질을 보다 확충하는 차원에서 특수학교(급) 고등부 졸업생의 진로 실태를 분석하고, 그 결과를 기반으로 현실여건에서 최상의 진로 지원체제 구축방안을 마련 하는데 목적을 두고 수행되었다. 이 연구는 목적의 달성을 위해 문헌고찰을 통해서 진로실태 분석모형을 개발하고 진로 지원체제 구축을 위한 요인을 발굴한 이후, 최근 5년간 전국 특수학교(급) 고등부 졸업생을 대상으로 전반의 진로실태를 조사?분석하고, 문헌분석 및 실태조사를 통해서 도출된 결과를 중심으로 학교와 지역이 연계된 진로 지원체제 구축 방안을 제시하였다. 먼저, 특수학교(급) 고등부 졸업생의 진로 실태에 대한 조사 결과를 제시하면 다음과 같다. 특수학교(급) 고등부 졸업생 진로실태 조사는 전국 120개 특수학교(고등부 과정 설치 특수학교), 161개 고등부 특수학급 총281개 학교의 2001년도부터 2005년도까지 5년간 졸업생 1,334명을 조사대상으로 하였다. 이들 조사대상 1,334명은 행정공문으로 각 학교별 졸업생 명부를 통하여 추출된 것으로, 실제 5년간 특수학교(급) 고등부 졸업생의 11.1%에 해당된다. 실태조사는 1차로 우편을 통한 설문지 발송과 회수를 통해서 이루어졌고, 2차로 본원의 현장연구위원 교사 176명이 소속 지역교육청의 졸업생을 직접 방문하여 설문 및 면담 조사실시하는 방법을 통해 이루어졌다. 조사결과에 의하면, 특수학교(급) 고등부 졸업생의 35.2%가 직장을 가진 취업자이고, 64.8%가 직장을 가지지 않은 미취업자(가정거주, 시설거주, 자영업, 대학진학포함)로 조사되었다. 장애영역별 학교 졸업생의 진로 실태를 취업률 중심으로 제시하면, 시각장애학교 졸업생 36.8%, 청각장애학교 졸업생 45.4%, 지체부자유학교 졸업생 35.1%, 정신지체 및 정서장애학교 졸업생 31.7%, 특수학급 졸업생 39.5%로 나타났다. 한편, 졸업생의 연도별 추이를 취업률 중심으로 제시하면, 2001년도 졸업생 45.3%, 2002년도 졸업생 32.8%, 2003년도 졸업생 32.2%, 2004년도 졸업생 31.3%, 2005년도 졸업생 33.8%로 나타났다. 최근 5년간 특수학교(급) 고등부 졸업생의 진로실태 전반에서, 미취업자는 가족과 함께 생활하지 않은 장애성인이 많고, 학교 졸업이후 무직상태가 지속되고, 직장생활을 원하지만 특별한 지원을 받지 못하고 있으며, 전반적인 생활만족도가 낮은 것으로 나타나고 있다. 한편, 취업자의 경우, 직장생활을 하고 있는 그 자체의 만족도를 제외하고는 고용상황 전반이 열악하고, 직장의 직무수행에 다소의 어려움을 느끼고 있고, 직장의 이직률이 높지만 적절한 지원을 받고 있지 못하며, 직장의 적응 · 유지를 위한 직업훈련을 받지 못한 경우가 많고, 현 수준보다 높은 임금을 지급하는 안정된 직장에 대한 요구가 많은 것으로 나타나고 있다. 또한 직장 생활의 직무수행 효율화를 위하여 장애인식 개선 혹은 장애인편의시설 확충에 대한 요구가 많은 것으로 나타나고 있다. 이와 같은 연구의 결과를 토대로 진로 지원체제 구축을 방안을 제시하면 다음과 같다. 특수학교(급) 고등부 졸업생의 진로 지원체제 구축 방안은 진로교육 대상자의 ‘개별성’과 진로발달 단계의 ‘연속성’을 보장하고, 진로 관련 기관간의 ‘협력성’을 강조하는 진로 지원체제의 구축이 필요하다는 방향성을 설정하고, 다음과 같은 구체적인 방안이 필요하다고 보았다. 첫째, 학령기 특수교육 대상학생의 직업 · 진로교육 실시를 위한 기반을 조성하여야 한다. 특수교육 진로관련 다양한 용어들을 정비하고, 직업 · 진로 관련 법규의 수정 및 보완이 이루어져야 하며, 개별화교육계획(IEP)에 개별화전환계획(ITP)이 포함되도록 하는 법규의 재정이 필요하다. 이를 통해서 단위 특수학교(급)에서 진로교육이 시스템적으로 실천되도록 하는 토대를 마련하여야 한다. 둘째, 현행 특수교육 직업 및 진로 관련 교육과정의 현실화가 이루어져야 한다. 현행 제7차 특수학교 교육과정 기본교육과정의 ‘직업교과’ 교육실시 시기를 앞당기고, 선택중심 교육과정 ‘전문선택’의 이수 범위를 확대할 필요가 있으며, 이를 통해서 현실성 있고 실제적인 단위 학교의 직업 및 진로교육 교육과정 운영이 이루어지도록 해야 한다. 한편, 특수학급 재학생들의 직업 및 진로교육을 효율적으로 실천하기 위한 근거를 국가수준 교육과정 문서에 마련하고, 다양한 교과에 산재된 진로관련 내용을 지도할 수 있도록 교사용 지도서를 제작 · 배부하여 활용토록 해야 한다. 셋째, 특수교육 대상학생을 위한 진로교육 방법의 개선이 이루어져야 하다. 직업 · 진로교육을 위한 일관성 있는 모형을 마련하여 적용하여야 하며, 진로교육의 효율적인 실시를 위하여 평가체제 및 평가주체를 명확히 확립하고, 직업 · 진로교육의 효율적인 실시를 위하여 전문 인력을 양성하여 배치하여야 한다. 또한, 특수교육 대상학생을 위한 직업 및 진로교육은 현장친화적인 교수-학습이 이루어지도록 하는 방법상의 변화를 모색해야 하며, 현장을 중심으로 하는 다양한 진로교육 모델을 개발하여 개별학생들의 요구와 필요가 충족되도록 하여야 한다. 넷째, 특수교육 대상학생의 졸업 시 진로선택의 역량 및 지원의 강화가 이루어져야 한다. 특수교육 대상학생의 자기결정 능력을 지속적으로 향상시키고, 이를 통해서 자신의 진로를 선택하고, 선택한 진로를 유지 · 발전시킬 수 있도록 그 역량을 강화해야 한다. 또한 특수교육 대상학생의 가족이 학교의 진로교육, 지역의 진로지원을 위한 프로그램의 계획 · 실행 · 평가 전반의 과정에 효율적인 참여가 이루어지도록 지원해야 한다. 한편, 학교와 지역의 직업 · 진로관련 기관 및 인사 간을 연계하는 가칭 ‘연계 및 협력 조력자’를 양성하여 활용토록 해야 한다. 다섯째, 장애성인의 지역사회에서의 효율적인 진로 지원을 위하여 다양한 지원 프로그램이 마련되어야 한다. 특수학교(급) 고등부를 졸업한 대학진학자와 미취업자는 항시 취업대기자이기 때문에 이들을 위한 대학 당국과 평생교육기관에서의 진로 지원을 위한 다양한 프로그램을 마련하여야 한다. 또한 특수학교(급) 고등부를 졸업한 취업자를 위해서는 직업 적응 및 유지, 직업 이동을 위한 준비 프로그램, 인턴 프로그램, 사후관리 프로그램을 마련하여 지원이 이루어지도록 해야 한다. 또한 국가는 범정부 차원의 특수교육 대상학생 직업 및 진로 촉진을 위한 추진 기구를 구성하여 운영하고, 장애학생 및 장애성인의 취업활성화를 위한 정책적 지원 기구와 방안을 강구하여야 한다. 이상에서와 같이, 특수교육 대상학생의 진로교육 및 진로지원은 그들의 삶의 질 향상에 목표를 두고, 진로 대상자의 개별성과 진로발달 단계의 연속성, 관련 기관간의 연계성을 기반으로 하는 학령기, 졸업시점, 학령기 이후가 통합된 적절한 지원체제를 마련해야 한다. 이와 같은 진로 지원체제가 현실성을 가지고 효율적으로 작동하게 된다면, 대부분의 일반인이 그렇듯 장애인도 직업을 가지고, 일과 노동의 댓가로 보수를 받으며, 받은 보수로서 세금을 납부 하면서 국가와 사회에 기여하고, 가정을 유지하면서 자신의 만족감을 가지며 살아가는 데 기여하게 될 것이다. The purpose of this study was to suggest the future directions and practices for developing a comprehensive career support system in special education school, based on the analysis of the actual career status of the high school graduates with disabilities in Korea. The research was conducted in several ways. First, by reviewing the related research and the literature, the analytical frame for the actual career status was developed and the considerable factors for the development of a comprehensive career support system were identified. Second, the nation-wide survey was conducted to overview and to analyze the actual career status of the students who graduated special education high schools over the last 5 years. Third, based on the literature review and the results of the survey analysis, the future directions and best practices for the comprehensive career support system were suggested. First, the nation-wide survey was conducted in the following. The subjects were 1,334 high school graduates from both 120 nation-wide special education schools (these schools include the course of high school) and 161 special education classes among 281 general education high schools from 2001 to 2005. The subjects were identified through the school graduate lists. And they were 11.1% of the total graduates both from special education schools and special education classes over the last 5 years. The first preliminary survey was conducted by mailing the questionnaires in returning envelops. The second survey was conducted by the 176 teachers who served as research committee members of the KISE. The teachers conducted in-depth surveys and interviews by calling on the graduates who belonged to their local school districts. The survey results showed that 35.2% of the graduates were employed and 64.8% were unemployed (staying at home, living in the facilities for people with disabilities, self-employed, and attending college or universities). The survey results according to the schools classified by the disabilities indicated the following employment rate; 36.8% of the graduates from the school for the visual impairments, 45.4% of the graduates from the school for the hearing impairments, 35.1% of the graduates from the school for the physical disabilities, 31.7% of the graduates from the school for the mental retardation and emotional disorders, and 39.5% of the graduates from the special education classes. On the other hand, the employment rate were different by the year; 45.3% of the graduates in 2001, 32.8% in 2002, 32.2% in 2003, 31.3% in 2004, and 33.8% in 2005. In general, the actual career status of the high school graduates with disabilities over the last 5 years were identified for the unemployed graduates; a) many unemployed graduates did not live with their family; b) the status of unemployment went on after high school graduation; c) most unemployed graduates wanted to have occupations, but there were little support for employment, such as vocational education programs; and d) their overall level of satisfaction in life was low. Meanwhile, the employed graduates also indicated that their employment condition was poor, except the fact that they had some satisfaction for them to have jobs. The actual career status for the employed graduates were identified in the following; a) their overall employment condition was poor; b) they felt some difficulties for carrying out their jobs; c) a change of occupation rates were high without proper support, d) there were little job training for adapting a new workplace and for maintaining their current jobs; d) there were high expectations for stable jobs with better wages than their current jobs; and e) they also requested for improving the convenient facilities for the people with disabilities and for increasing the understanding and the awareness of people with disabilities for their work efficiency. Based on these findings of the high school graduates with disabilities, the future directions and practices for developing a comprehensive career support system in special education school are suggested; a) the individualities of each student with disabilities and the continuity of career development are ensured, and b) the collaboration among schools, the community resources, and the employment agencies are emphasized. Therefore, it is necessary to draw a concrete plan in the following. First, the foundation of vocational education and career services should be established firmly for the students with disabilities in school. It is necessary to compile the glossary for the vocational education, career services, and transition in special education. It is also required to amend and make laws related to vocational education and career services, and to mandate the TP(Individual Transition Plan) to be included in the IEP(Individualized Education Program). Through these laws and policies, a firm basis for the systematic vocational education should be implemented. Second, the present vocational education and career related curriculum should be actualized. The 'vocational course' of the 7th Special Education Curriculum should be taught earlier, the 'specific elective courses' from the choice-based basic curriculum should be expanded in order to implement the school-based vocational career education curriculum practically and realistically. At the same time, these suggestions should be mandated by the national curriculum. And the teacher's manual should be prepared and distributed for teachers to effectively guide students for their vocation and career preparation. Third, the vocational education teaching strategies for students with disabilities should be improved. The consistent model for the vocational and career education as well as the effective assessment system should be developed and implemented. And for the effective implementation of the vocational and career education, the professionals should be trained and be placed in school. Moreover, the model for the vocational and career education for students with disabilities should utilize the field-based teaching and learning strategies. Especially, the field-based model needs to be diverse in order to meet the individual students' needs. Fourth, it is essential to strengthen the ability and to support the career choices of students at the time of graduation. It is necessary to continually make better for their self-decision ability. Through their self-decision ability, they can make their career choices and strengthen the ability to keep and develop their chosen careers. In addition, the families of students with disability should be supported in order to participate effectively in vocational and career education in schools and the whole process of planning, implementation, and the assessment for the career support within the community. Therefore, the 'transition coordinator', who can make connections and cooperations among schools, community resources, and the employment agencies, should be trained and utilized. Fifth, a variety of supportive programs for adults with disabilities must be provided in order to ensure the effective career supports in the communities. Since the students who went to college or universities after graduating special education high schools(classes) and the unemployed high school graduates are potential employees, the university authorities and the continuing education agencies must have a variety of supportive programs for them. Besides, it is essential to have specific programs for a job adaptation and sustainment, job preparation program for a career change, various internship programs, and the follow-up programs. In addition, the government should have the special organization for promoting the employment of the students with disabilities and adults with disabilities as well. In conclusion, the purpose of the vocational and career education for the students with disabilities should be the improvement of their quality of life. Therefore, based on the individuality of each student with disabilities, the continuity of career development stages, and the inter-agency collaboration, the comprehensive career support system should be integrated throughout the schools years, at the time of graduation, and after the graduation. If the suggested comprehensive career support system are to be implemented effectively within each school and each classroom, the people with disabilities will have occupations, get paid for the work they do, pay the taxes, have families, and contribute to the community and the nation with a feeling of great satisfaction, just as the most people without disabilities do.

Until recently, total splenectomy has been considered as a safe operation for splenic injuries under the misconception that the spleen could not heal spontaneously and the spleen was not necessary for the maintenance of life. Concurrent with the knowledge for immunologic function of spleen, a renewed int,erest has been evolved in the technique of splenic salvage, including splenorrhaphy, partial splenectomy, nonoperative management, and autotransplantation of splenic fragments. Authors have reviewed 47 patients with splenic injury admitted to the Department of Surgery, Dong-Guk University Hospital during the period from June, 1987 to December, 1993. The patients were classified in accordance with Cogbill s splenic organ injury scale which defines five categories for the splenic injury. Among them 30 patients were treated by splenectomy, 2 patients by partial splenctomy, 11 patients by splenorrhaphy, and 4 patients by nonoperative management. In conclusion, nonoperative management is a safe treatment option if the following criteria are satisfied: 1) absolute hemodynamic stability or rapid hemodynamic stabilization after fluid resuscitation : 2) lack of other serious intraabdominal injuries: 3) Class I or ll splenic injury by Cogbill s method.

With the increment of the role of CT scan, nonoperative treatment is the recent trend in hemodynamically stable patients in the management of traumatic liver injuries. To investigate the trend of treatment and to suggest the possible criteria for nonoperative treatment, we reviewed 50 patients with traumatic liver injuries who were treated in the Department of Surgery, Dong-Guk University Hospital from January 1989 to June 1994. Of 50 patients, 35 patients were treated with nonoperative management and 15 patients were treated with operative management. Based on CT findings, we classified those 50 patients into each grade of liver injuries ranging from grade 1 to 5 and we classified t,he degree of hemoperitoneum ranging from grade 0 to gracle 3+, and we compared those results with the clinical outcome. The operation rate according to liver injury grade didn't increase with the increment of the grade, and the degree of hemoperitoneum corresponds well to the rate of operation. In the nonoperative cases, there was only one complication and there was no mortality. In conclustion, even major liver injuries including grade 4 by CT scan can be treated with nonoperative rnanagement if the patients are hemodynamically stable and they do not have combinded intraabdominal organ injury.

완전뇌허혈후 재관류시에 국소뇌혈류, 체성감각유발전위 및 신경학적 회복에 대한 Mannitol과 Thiopental의 효과

박춘근,이상원,박영섭,최승진,허필우,정동섭,강준기,최창락 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.2

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.
