연구목적: 인지와 정서의 기능장애로 정의되는 정신분열병은 정보처리와 관련되어 특히 긴장된 배경자극하에서 감정적인(특히 부정적인) 자극이나 큐를 정확하게 인식하는데 어려움이 있으며, 감정이 심하게 부하된 상황에의 노출이 재발의 원인이 된다. 이러한 정신분열병에 있어 정서 자체의 중요성에도 불구하고 사회적임성을 증진시키는 기존의 기술훈련은 감정처리가 주 치료목표가 되지 못하고 감정부하 상황만이 주어졌다. 따라서 본 연구는 정서처리를 직접, 간접적으로 다루는 감정관리훈련(Emotional Management Training; EMT)을 소개하고, 정신분열병 환자에의 적용을 통해 그 효과를 고찰하고자 하였다. 방 법: 정신분열병 환자 30명을 대상으로 12주동안 주 2회, 1회당 60분씩 EMT를 시행하였고 대조군으로 23명의 정신분열병 환자에게 정신건강교육을 같은 기간 동안 실시하였다. 치료전후에 정서영역의 평가로 Trait Meta Mood Scale-short form(TMMS-S), 사회적 큐와 관련된 사회지각능력의 평가를 위해 사회지각척도, 인지영역의 평가로 언어유창성검사, Verbal paired associate learning, 유사성검사를, 정신병리의 평가로 Positive And Negative Syndrome Scale(PANSS)를, 마지막으로 다양한 측면의 사회문제해결능력의 평가로 Social Problem Solving Inventory(SPSI)를 시행하여 이 훈련의 치료 효과를 알아보았다. 결 과: EMT 시행군이 대조군에 비해 사회지각척도의 시각적 지각능력, 언어유창성, PANSS의 양성증상 및 일반병리와 총 점수, 그리고 SPSI의 총점수와 문제지남력 점수가 유의미한 호전을 보였다. 그러나 추상적 기능 및 언어성 기억력, 음성증상, 문제해결기술척도에서는 뚜렷한 효과가 관찰되지 않았다. 결 론: 감정관리훈련은 일반적으로 정신사회적 재활의 궁극적인 목적 가운데 하나인 사회 혹은 대인관계 문제해결을 위한 동기적 측면과 해결과정의 초기 단계에 유용한 프로그램이 될 수 있음을 시사하며 감정이 부하된 상황에 대한 친숙성을 증가시킨다고 할 수 있다. Objectives: Schizophrenic patients having a disturbance of cognition and emotion are least likely to identify emotional(especially negative) stimuli and cue in tense background stimuli. Also, schizophrenic patients tend to experience relapse if they are exposued to a situation which is emotionally laden. Although emotion itself is important, emotional processing has not been a therapeutic target and skill training which improves social competence has provided patients with emotional load. Therefore, we introduced Emotional Management Training(EMT) which deal with indirect and direct emotional processing, applied it to schizophrenic patients, and investigated the therapeutic effects. Methods: We applied the Emotional Management Training(EMT) to 30 schizophrenic patients for 12 weeks, 2 times every week and psychoeducation to 23 schizophrenic patients as control group attention-placebo for 12 weeks, during the same period. Before and after treatment, we used the Trait Meta Mood Scale-short form(TMMS-S) as emotional proper, Social Perception Scale, Verbal Fluency Test, Verbal Paired Associates, and Similarities for cognitive functions. We also used Positive And Negative Syndrome Scale(PANSS) as psychopathology measurement and Social Problem Solving Scale(SPSI) as various kinds of social problem solving function measurement before and after treatment. Results: The results showed that EMT group appeared to be more effective in improving the visual perception of social perception scale, verbal fluencies, positive symptoms, general psychopathology, and total score in PANSS than the control group. Also EMT group seemed to be more effective in total score and Problem Orientation score in SPSI than the control. But there were no differences in abstract function and verbal memory, negative symptoms, and Problem-Solving Skill score between the two groups. Conclusion: This study suggests that despite the limitations of the generalizability and the questions for the persistence of effectiveness, EMT might help schizophrenics get the motivational aspects, the familiarity with emotional-loaded situation, and initial processes, for social problem-solving.

Measurement uncertainty should be evaluated according to ISO/IEC 17025. In Flow measurement area, uncertainty evaluation scheme was applied to the reference flow meter, sonic nozzle. Uncertainty was calculated by evaluating various uncertainty factors affected in flow measurement. The expanded uncertainty(U) of the sonic nozzle was 2.1$\times$ 10$^{-3}$ (confidence level of 95 %). This evaluation example will be useful in flow measurement uncertainty determination of other flow meters.

A sonic nozzle is used as a reference flow meter in the area of gas flow rate measurement. The critical pressure ratio of sonic nozzle is an important factor in maintaining its operating condition. ISO9300 suggested the critical pressure ratio of sonic nozzle as a function of area ratio. In this study, 13 sonic nozzles were made by the design of ISC9300 with different half diffuser angles of 2。 to 8。 and throat diameters of 0.28 to 4.48 mm. The test results of half diffuser angles below 8。 ar quite similar to those of ISO9300. On the other hand, the critical pressure ratio for the nozzle of 8。 decreases by 5.5% in comparison with ISO9300. However, ISO9300 does not predict the critical pressure ratio at lower Reynolds numbers than 10(sup)5. Therefore, it is found that it is a better way for the flow of low Reynolds number to express the critical pressure ratio of sonic nozzle as a function of Reynolds number than area ratios. A correlation equation of critical pressure is introduced with uncertainty $\pm$3.2 % at 95% confidence level.

Cerivastatin is novel HMG-CoA reductase inhibitors. Clinical trials showed no significant differences of serum creatine kiase between cerivastatin and placebo, and cerivastatin-induced myopathy was rarely reported. This beneficial effect of cerivastatin is thought to be related to the the dual pathway metabolism by hapatic CYP3A4 and 2C8. We here report three cases of rhabdomyolysis which is associated with cerivastatin therapy. Two patients had diabetes mellitus, and received cerivastatin( 0.8 mg/day) for treating hyperlipidemia and the other patient had chronic renal failure due to diabetic nephropathy and has maintained peritoneal dialysis and received cerivastatin(0.4 mg/day). Within one month of cerivastatin treatment, those patients experienced myalgia or muscle weakness. At that time, laboratory findings including muscle enzyme level, and bone scan finding were compatible with rhadomyolysis. Under the impression of cerivastatininduced rhabodmyolysis, cerivastatin was withdrwan, and conventional treatment for rhabdomyolysis was started. Clinical course was uneventful, and these patients were discharged with good general condition. In conclusion, cerivastatin is regarded as a safe drug as compared with other statins, but it also causes rhabdomyolysis. Careful history taking and regular follow-up of muscle enzyme levels would be necessary to detect cerivastatin-induced rhabdomyolysis.

Our research proposes how to, systematically, count function point from initial functional requirements based on natural language. Gradually, Function Point Analysis is used to overcome the limitation of LOC(Line Of Code) for estimating software size. Moreover, it plays an important role in cost management. Function point is derived from initial requirements and is determined by experts who have an education for function point. However, currently there are few researches to cout function point by systematic or automatic rules. Through extending our porposed method, we expect that function point is able to be counted automatically or semi-automatically. This would be our future research
