The basic aim of this study is to utilize PCM(Phase Change Material) that is required for storage of solar energy. PCM's thermal, physical characteristics are affected by temperature. PCM is easy to change one into another phase at low temperature. While the temperature change makes the PCM melted or solidified, an amount of energy can be transfer. In order to evaluate the PCM's characteristics and its phase change related to heat transfer, 3 dimensional computer simulation is adapted and its analysis is accomplished. The simulation was carried out under changing of temperature for an insulated cylinder filled with PCM and the PCM's thermal characteristics was observed based on time.

Fine needle aspiration(FNA) cytology is considered as the diagnostic technique of choice in the assessment of swellen lymph nodes. The aim of this study is to determine the indication and diagnostic method of FNA of lymph node lesions performed at Veterinary Medicine Teaching Hospital of Chungnam National University. The records of 16 patients which had undergone FNA during the study period were retrieved. The cytological results were classified as lymphadenitis, lymphoid hyperplasia and lymphoma. Lymphoma cases were classified as B-cell origin and T-cell by immunophenotyping. The result of the FNA cytological diagnosis showed that nine (56%) of the patients were lymphoma, five (31%) of the patients were lymphoid hyperplasia and two (13%) of the patients were lymphadenitis.

To evaluate the accuracy and diagnostic significance of cytopathological diagnosis of canine splenic disorders, cytopathological examination throgh fine-needle aspiration(FNA) referred to Veterinary Medical Teaching Hospital of Chungnam National University were retrospectived. Splenic neoplasm, hemolymphatic neoplasm, hyperplasia, extramedullary hematopoiesis and splenitis were diagnosed canine splenic disorders through cytopathological examination. The patient should be identified what coagulation profile are normal before aspiration, because complication such as hemorrhage could happen. The 4 cases were identified symmetric, asymmetric splenomegaly on abdominal ultrasonography and then were performed ultrasound-guided FNA. The 4 cases were diagnosed hemangiosarcoma(2), hyperplasia(1) and extramedullary hematopoiesis(1) by clinical signs, hematological examination, and cytopathological examination. Cytopathological examination through FNA was cost-effective, no gneral anesthesia, no complication, and non-invasive method of diagnosis for canine splenic disorders.

Study objectives: To compare the quality of CPR provided by medical students and pre-EMTs perfoming three-rescuer CPR with that achieved by same students trained to provide standard two-rescuer CPR and to find the most effective method of resuscitation and to educate this methods to students. Material and methods: From July 1 to September 30, 1996, we had trained 60 groups consisted of the medical students, students of EMS technology and pre-EMT. Each group practiced two-rescuer CPR and three-rescuer CPR for 120 minutes with Resusci? Anne and perfomed CPR for at least 3 minutes without feedback. To eliminate any visual cues of perfomance the mannequin's recorder was hidden. Each actions were recorded by Resusci? skillmeter and Laerdal printer. To compare the quality of two-rescuer CPR and three-rescuer CPR, we analyzed the data by SPSS with paired t-test. Results: Three-rescuer teams delivered a mean minute ventilation and a mean minute cardiac compression substantially greater than that produced by two-rescuer teams(11.30±1.85 vs 9.09±2.22, p<0.001; 99.22±12.42 vs 95.12±15.75, p<0.001). Three-rescuer teams produce the more correct actions in chest compression and ventilation(93.84±7.56% vs 83.49±16.94%, 90.90±9.33% vs 77.00±17.06%). Conclusion: Three-rescuers can produce better CPR than two rescuers when a bag-valve-mask devices is used and the technique is easily learned and readily retrained, so we think that repeated education and training of this CPR methods to students is needed.

The purpose of this research is to provide guiding alternatives of sound leasure activities by breaking with terms for types and behaves of its in university student's daily life. For these me, students who took class on 「Theory of leisure, has been studied concepts of leasure spontaneously as a observer, and then they has been submitted to diary-style life record table which are done activities of one week. By doing practice on diary analysis method on basis of one's life record, which are analyzed student s life and act for one week by emphasis upon leasure time. And also to increase reliance on research results, by presenting in class examples of 10 persons among main interview group, whether are unified with their opinions. The results has been shown that portion of leasure activities has various value at range of 15.7~38.0 percentage on total activities time. Most examples have presented that students have been spent leasure time efficiently, after they have examined with leasure time and made life record by themselves.

Clozapine은 추세외로 증상과 지연성 운동장애를 거의 일으키지 않는 비전형 항정신병 약물로서 치료 저항성 정신분열증 환자들의 치료에 우수한 효과가 있는 것으로 알려져 있다. 그러나 기존의 항정신병 약물로 치료를 받고 있는 환자들의 약 1%에서 경련이 발생하는 것과 비교해서 clozapine를 투여받는 환자들은 경련의 발생 비율이 보다 높은 것으로 알려져 있다. 또한 이러한 경련은 clozapine의 투여에 의해 점차적으로 경련의 역치가 낮아져 발생하게 되므로 clozapine의 용량이 증가함에 따라 경련의 발생 비율도 함께 증가하는 것으로 보고되어져 왔다. 저자들은 정신분열증 환자들에게 clozapine을 투여하던 중 이전의 보고들과는 달리 저용량에서 전신성 경련이 발생한 환자 4례를 경험하였다. 본 증례에서는 경련이 clozapine을 증량하여 투여한 직후에 발생하였기 때문에, 약물의 용량보다는 clozapine 투여 후에 혈중 clozapine 농도가 급격히 증가하는 것에 기인한 것으로 생각되었다. 본 증례를 통해 저자들은 치료 저항성 정신분열증 환자들에게 clozapine을 투여할 경우 고용량 투여, 급격한 증량에 주의한다면 경련을 최소화할 수 있다고 생각하였다. Clozapine is an atypical antipsychotics that has shown to be effective in treating patients with refractory schizophrenia and those with intolerance to currently available antipsychotics. It also appearer to be less likely to cause extrapyramidal symptoms and tardive dyskinesia. But clozapine has been associated with an unusual high incidence of seizures in patients with no previous history of ictal episodes. Seizures occur in approximately 1% of patients treated with antipsychotic drugs. But the prevalence is higher with clozapine. Clozapine-induced seizures are reported to occur in a dose-related manner by progressively lowering the seizure threshold on most all patients as the dose is increased. But seizure does not usually necessitate discontinuation of clozapine treatment. We experienced four cases of seizure induced by low doses of clozapine treatment in schizophrenic patients. Since most of the seizures have occured soon after increase of a clozapine dose, they may have related more to rapid increase in blood clozapine levels than to that of dose. It is also possible that dose did not accurately predict blood levels for these patients. The possibility of seizures should not pose a barrier a barrier to clozapine treatment for patients with refractory psychotic disorders. The risks and morbidity of seizures can be minimized through attention to clinical management.

중독한 추체로 증상을 보인 cyclosporine에 의한 뇌증 1예

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.
