This study focused on adjusting the graphic organizer not only on Korean but also on mathematics and social studies It also focused on writing how the graphic organizer is related to the self-directed learning. The purpose of this study was to investigate the self directed learning on the learning activities applying the graphic organizer. This study sampled two 3rd grade classes in an elementary school, in Gumi, to select an experimental group and comparative group. Through the pre-test of self-directed learning, the two groups are verified as equivalent groups. Classes using the graphic organizer were performed to the experimental group, while classes based on the teacher's guide of the 7th national curriculum to the comparative group. The results of this study were as follows; First, in the pre-test result, there was no difference between the experimental group and the comparative group. However, after applying the program, it helped students' openness, effectiveness, responsibility, and passion for learning. It also developed their tendency for the future, creativity, basic learning ability and problem solving literacy. Second, teaching logs were written for qualitative data to supplement the limitation of the quantitative research. The data showed the development of students' understanding and creative thinking. Ability to think and analyze improved in the process of deciding the order of accidents or choosing the suitable graphic organizer.

Standard reference materials(SRM) have been used to certify the degree of accuracy for determining various kinds of analytes including environmental organic contaminants. In this study, we collected sediments from the Nakdong River estuary and Ulsan Bay. The levels of polychlorinated biphenyls(PCBs) and organochlorine pesticides were determined to investigate the availability of SRM and its homogeneity. The 8 congeners of PCBs and chlordane, p,p'-dichlorodiphenyldichloroethane(DDD), p,p'-dichlorodiphenyldichloroethylene(DDE), p,p'-dichlorodiphenyltrichloroethane(DDT), dieldrin, hexachlorobenzene(HCB) and oxychlordane were determined by using a capillary column gas chromatography/electron capture detector system. The environmental levels of these species md their relative standard deviations are discussed.

목적 : 본 연구에서는 특수교육지원센터에서 시행되는 치료지원서비스의 인식, 목적, 특징 및 개선방안을 살펴봄으 로써 치료지원서비스의 전반적 실태를 파악하고 이를 통해 최적의 치료지원서비스를 제공하기 위한 기초자료로 제시하고자 한다. 연구 방법 : 현재 특수교육지원센터에서 치료지원서비스를 받고 있는 치료지원대상 아동의 보호자를 대상으로 개별 인터뷰가 진행되었다. 인터뷰는 평균 40분이 소요되었으며, 모든 인터뷰는 녹취되었다. 결과 : 치료지원서비스에 대한 근본적인 인식이 부족하였고, 치료영역의 전문가가 치료를 담당함으로 인하여 치료사에 대한 신뢰도가 높은 것으로 조사되었다. 또한 치료실의 시설 및 교재교구의 다양성으로 인해 질적으로 높은 치료를 받는다고 생각하고 있었으며 모든 연구대상자는 무상교육을 치료지원서비스의 특징으로 꼽았다. 결론 : 작업치료사가 특수교육지원센터에서 치료지원서비스 전문가로 자리 매김하기 위해서 많은 노력과 연구 및 대외적인 홍보가 필요하다. Objective : The purpose of this study is to provide practical guidelines for the better performance of the Occupational therapy services(OT services) in the Supporting Center for Special Education. The study is based upon the quality and satisfaction of the OT services, measured by interviewing parents whose children have taken the services provided by Ulsan Kang-Nam Supporting Center for Special Education. Methods : Five parents for the children having OT services since March, 2010 in the Kang-Nam Supporting Center were interviewed individually. The interview per each person took thirty to fifty minutes and was all audio-recorded. Results : The satisfaction of the qualification for the OT therapists working at the Kang-Nam Supporting Center was high. The quality for treatment facilities and the variety for treatment materials met the expectation for OT to be well-performed. The free OT treatment system was the one of significant features for the OT services provided by the Kang-Nam Supporting Center. However, the perception of the interviewed parents for the OT was very low.

Spraque-Dawley계 수컷랫트에 계통분획한 단풍취의 각 분획물을 경구투여하고 혈청 ethanol농도와 간의 ADH활성에 미치는 효과를 검색 추적한 결과 알코올대사를 촉진시키는 성분은 주로 에탄올가용부에, 억제시키는 성분은 에탄올불용부에 주로 존재함을 추정할 수 있었고 현재 활성성분을 분리중에 있다.(1998년 9월 25일 접수, 1998년 10월 14일 수리) Effects of organic solvents fraction from Ainsliaea acerifolia ethanol extract on alcohol metabolism in rats were examined and the results were as follows: Ethanol souble fraction, after a single oral administration to rats, was found to cause a significant decrease in the serum ethanol concentration as well as enhancement of liver cytosolic alcohol dehydrogenase(ADH) activity, on the other hand, the fraction insouble in ethanol was found to cause an increase ethanol concentration in the blood and inhibit ADH activity.

혈청이 마우스 간 세포주 BNL CL.2의 Nitric Oxide 생성에 미치는 영향

마우스 간 세포주인 BNL CL.2의 시험관내 배양에서 혈청과 IFN-γ가 세포주의 nitric oxide(NO) 생성과 세포 손상에 미치는 영향을 알아보기 위한 실험을 하였다. 혈청이 공급된 배양에서 IFN-γ에 의한 세포 생존율은 거의 변동이 없었으나, 혈청을 제거한 배양에서는 약 65%의 생존율이 유지되었으며, NO 생성 억제제인 N -monomethy-L-arginine (NMA)의 첨가는 농도 의존적으로 세포의 생존율을 감소시켰다. 혈청이 제거된 BNL CL.2세포주는 IFN-γ단독 처리에서도 NO 를 생성할 수 있었으며, IFN-γ와 lipopolysaccharide (LPS)의 복합 처리는 세포주의 NO 생성을 상승적으로 증가시켰다. 또한 protein tyrosine kinase (PTK) inhibitor인 herbimycin A와 genistein에 의해서 NO 생성이 억제되어 PTK의 활성이 혈청이 고갈된 BNL CL.2 세포에서 NO의 생성에 중요한 역할을 담당하고 있기 때문으로 판단된다. IFN-γ의 독성은 혈청을 제거시킬 때 NO 생성 억제제에 상승적으로 간 세포를 손상시키며, 이때 NO가 IFN-γ에 의해 유도된 손상을 어느 정도 억제시키는 것을 알 수 있었다. Nitric oxide (NO) plays an important role in immunologic defense, and influences upon the functioning of secretory tissues and cells. It also exhibits cytotoxic/cytostatic activity as one of major operating effectors of the cellular immunity system. We investigated the effects of serum on the cell damages and NO production in the mouse liver cell line BNL CL.2 to establish the role of NO. We observed that, when BNL CL.2 cells were cultured in serum-free medium, they were induced to cell damage by the stimulation of IFN-γalone or IFN-γplus LPS. Serumstarved cells showed large amount of nitrite accumulation and NO synthase (NOS) expression in response to IFN-γalone in dose-and time-dependent manners, but serum-supplied cells did not. The production of NO was blocked by protein tyrosine kinase (PTK) inhibitors, genistein and herbimycin. These results suggest that the deprivation of serum in the BNL CL.2 cell culture medium might primed with the cells to produce NO when the cells are triggered by IFN-γ and the involvement of PTK signal transduction pathway in the expression of NOS gene in murine hepatocytes.
