Thromboelastography(TEG) is the unique measure that gives rapid information about the whole clotting process. Simplifying the diagnosis of coagulopathy during operations, TEG can provide an adequate therapy for postoperative bleeding. Remarkable improvement in hemostasis after cardiopulmonary bypass(CPB) has been achieved by the treatment with proteinase inhibitor aprotinin, but the hemostatic mechanism of aprotinin during CPB is still unclear. This study was designed to evaluate the effects of aprotinin on coagulation system during CPB by using TEG. Forty patients who underwent CPB were divided into two groups: aprotinin(2u 106 kallikrein inhibition units, as a single dose into the cardiopulmonary bypass priming solution) treatment group(male 14, female 8, mean age=50.Byears) and no aprotinin treatment(control) group(male 10, female 8, mean age=53.4 years). TEG, activated clotting time, prothrombin time, activated partial thromboplastin time, platelet counts, fibrinogen an (ibrinogen degradation product(FDP) concentrations were checked before and after CPB(30 minutes after neutralization of heparin effect by protamine sulfate). There was no significant difference in other conventional coagulation tests of two groups except postcardiopulmonary bypass FDP concentration in control group, which was significantly increased compared to that in aprotinin group(p<0.05). In TEG variables of both groups, clot formation time(K) and alpha $angle(\alpha^{\circ})$ were significantly increased and decreased, respectively, after CPB(p<0.05), but fibrinolytic index(LYS60) was not changed during CPB. In aprotinin group, reaction time(R) was decreased significantly after CPB(p<0.05) but maximum amplitude(MA) was not changed(p>0.05). On the contrary, R was not changed markedly but MA was decreased significantly in control group after CPB(p<0.05). This result shows that main change in coagulation system during CPB is not hyperfibrinolysis but cecrease in clot strength by platelet dys unction, and the main effect of aprotinin during cardiopulmonary bypass is the maintenance of clot strength to the pre-CPB level by the preservation of platelet function.

The purpose of this study is to inquire into the theoretical background of music therapy interventions for the improvement of mathematical concepts among young children with special needs. The researcher provides a basis of theoretical background about musical activities as an effective tool for young children to understand and promote their mathematical concepts, and the necessity of practical application in the field of mathematics education is suggested. Music, as a multi-sensory modality, has an ability to hold and maintain one's attention, and can be used as a memory aid and a powerful and effective motivator and reinforcer for young children. Therefore, musical activities can be used to facilitate mathematical concepts in the field of education for young children. Possible musical activities for promoting mathematical development are suggested, and the necessity for developing various musical activities is discussed.

Objective : We investigated that ADHD categorical diagnosis and the dimensional tools for the evaluation of ADHD, widely used in the clinical field, such as the child behavior check list- Korean version (K-CBCL), Korean personality inventory for children (KPI-C), computerized Attention Diagnostic System (ADS). Method : The DSM-IV clinical diagnosis applied by child psychiatrist. K-CBCL, KPI-C, ADS are used. Ultimately, totally 161 ADHD children and 161 controls were evaluated. Subject group are consist of 202 boys (62.7%) and 120 girls (37.3%), and the mean age was $9.5{\pm}2.0$ years old. Results and Conclusion : Social problem, and attention problem in the K-CBCL, correct response time standard deviation in the computerized ADS were statistically significant different and attention problem in the K-CBCL, hyperactivity subscale in the KPI-C were significant trait, between subject group and control group. The ROC value of attention problem in the K-CBCL, hyperactivity subscale in the KPI-C, and ADS were .78, .93, .86. Finally, we found that K-CBCL, KPI-C, ADS were significant corelation with the ADHD categorical diagnosis.

Chemotherapy and radiotherapy used on pediatric oncology patients often causes dentofacial anomalies. Defects noted include tooth and root agenesis, root thinning, root shortening, localized enamel defect and maxillofacial underdevelopment. The effect of radiotherapy usually is confined to the radiation site but the effect of chemotherapy may be more wide spread becuase of its systemic distribution. Many pediatric cancers are treated with a combination of radiation and multiagent chemotherapy. Dental treatment affected by chemotherapy and radiation therapy damage to developing teeth and maxilloface includes retention of teeth, space maintenance, prosthetic considerations, requirements for oral hygiene. The following case related to multiple rootless teeth.

This study shows that people with disabilities are very disadvantageous in employment and wage, which is originated from social discriminations. In this study, numerical value of employment-discrimination was calculated as 33.4%, and that of wage-discrimination calculated as 67.3%. But these discriminations are only come from one's disability not from productivity. So, Government must legislate 'The Discrimination Prohibit Act for People with Disabilities' rapidly to promote of people with disabilities' life qualities. Nobody knows when he get disabilities. Together with 'The Discrimination Prohibit Act for People with Disabilities', Government also have to improve people with disabilities' way of working, mobility, and provide assistive technology for the promotion of people with disabilities' employment rate and wage.

현대사회의 과학기술 발전은 반세기 전만하여도 거의 상상할 수 없을 정도로 빠른 속도로 발전하고 있으며, 이에 맞추어 생산시스템도 자동화되어가고 있는 추세이다. 그러나 아직도 생산작업의 약 1/3 정도가 사람의 인력에 의해 수행되고 있으며, 이에 따라 많은 산업재해도 발생하고 있다. 우리나라의 1993년부터 1996년까지의 산업재해 현황을 보면, 재해율은 감소추세를 보이고 있지만 산업재해 보상금과 간접 손실액을 합한 총 경제적 손실액은 오히려 증가추세를 보이고 있다. 또한 그 액수도 1956년에는 6조 7천억원에 달해 천문학적 수치를 보이고 있는 실정이다.

자신이 HIV에 감염되었다는 것을 아는 것은 커다란 충격이다. 감염사실을 알게 되면 충격에서 벗어나기까지 시간이 필요하며 어떤 정보나 조언도 받아들이기 어렵고 심지어 감염사실을 믿으려 하지 않는 경우도 있다. 사람들은 HIV에 감염되면 바로 죽는다고 생각하는데 이는 HIV에 대해 정확히 이해하지 못하고 있기 때문이다. 에이즈는 조금 까다로운 만성질환일 뿐, 감염사실을 미리 알고 치료를 잘 받으면 그다지 일상생활에 장애를 느끼지 않고 살 수 있다. 많은 어려움이 닥쳐오겠지만, 좌절하지 말고 좋은 정보와 치료를 통해 삶을 다시 꾸려나갈 수 있다는 믿음을 가져야 한다.

다이옥신의 독성은 체중의 감소, 간 대사효소의 증가, 면역억제, 정자 수의 감소, 발암 촉진 등 매우 다양한 양상을 나타내고 있다. 그러나 아직도 다이옥신이 어떻게 다양한 독성을 나타내는지에 대한 설명은 미비한 상태이다. 다만 다이옥신에 의해 증가되는 싸이토크롬 P450 lAl (CYPlAl) 효소 유전자의 전사활성화 기전연구를 통하여 다이옥신의 작용은 생체 내에 존재하는 다이옥신 수용체에 의하여 매개된다는 사실을 알게 되었다. (중략)

당뇨병으로 인한 태아의 위험은 당뇨병의 유전요인보다는 임신부의 대사 장애에 의한 것으로 당뇨병 형태에 따른 태아의 위험 차이는 없는 것으로 추축할 수 있다. 그러나 제 1형 당뇨병임신부는 케톤산혈증이 발생할 가능성이 높고 케톤산 혈증이 발생하면 태아 사망의 가능성도 높아진다. 또 제 1형 당뇨병임신부는 당뇨병성 혈관합병증이 동반될 가능성이 많아 자기의 주 수 보다 체중이 미달되는 경우와 조산 및 임신 중 고혈압질환이 발생할 위험성이 높아진다. 제 2형 당뇨병임산부는 임신부가 비만일 경우 거대아 출산 및 임신 중 고혈압질환이 발생할 위험이 높아진다. 그러나 대부분의 합병증은 임신 전과 임신기간 동안 양호한 혈당조절로 감소시킬 수 있다.

최근 일상생활이나 산업현장에서 생산공정의 기계화 또는 자동화로 인하여 수 작업이 많이 감소하였으나 아직도 정형화 되지 못한 물건의 운반, 부품조립 등 위 험요소를 내포한 여러가지 형태로 상지 동작(arm exertion)이 요구되는 인력운반 (manual material handling) 작업이 실제 작업현장에서 행새지고 있는 실정이며, 이러한 작업으로 인해 작업자들의 근골격계 부상으로신체장애의 사례가 늘어나고 있다.
