목 적 본 연구에서는 만성 정신분열병 환자에서 직업 유지 기간에 따른 증상 및 사회기능의 차이를 조사하여, 치료에서 보다 중점을 두어야 할 영역을 파악하고자 하였다. 방 법 양산병원 외래 진료를 받고 있거나 사회복귀 시설에 다니고 있는 정신분열병이나 분열정동장애로 진단 받은 환자 33명을 대상 자로 하였다. 4개월 이상 직업을 유지하고 있는 군을 장기군(12명)으로 하였고, 1개월 이상 직업 유지를 하지 못하는 군을 단기군 (10명)으로 하였으며, 직업을 가지지 못하는 군을 무직군(11명)으로 하였다. 모든 연구 참가자들에게서 개인면담을 통하여 일반 인구학적 특성과 임상적 특성을 조사하였고, 증상을 평가하기 위해서는 PANSS와 CGI를 사용하였으며, 우울증상, 사회-직업기 능, 주관적인 삶의 만족도를 평가하기 위하여 각각 Calgary Depression Scale for Schizophrenia, Social and Occupational Fun-ctioning Assessment Scale, SmithKline Beecham Quality of Life Scale을 사용하였다. 결 과 장기군은 단기군과 무직군보다 PANSS 점수의 총합, PANSS 음성증상 소척도 총점수가 유의하게 낮았으며, SOFAS 점수가 유의하게 높았다. 또한 장기군은 단기군보다 PANSS 양성증상 소척도 총점수, PANSS 일반정신병리 소척도 총점수, CGI 점수가 유의하게 낮았다. 결 론 장기군은 단기군과 무직군에 비해 증상 및 사회기능에 있어서 유의한 차이가 있었으며, 단기군과 무직군 사이에는 유의한 차이가 없었다. Objectives:This study of chronic schizophrenic patients was performed to investigate the differences in symptoms and social functioning according to the occupational duration, and to know domains to focus on in the treatment. Methods:33 schizophrenic or schizoaffective patients, from outpatients of Yang San Hospital or social rehabilitation facilities were divided into three groups:a group with job longer than 4 months(long term group), a group with job shorter than 1 month(short term group), and a group without job(no job group). Subjects were examined on sociodemographic and clinical features through out the interview, and their symptoms were assessed by PANSS and CGI, and their depressive symptoms, social-occupational functioning, subjective satisfaction about life were assessed by Calgary Depression Scale for Schizophrenia, Social and Occupational Functioning Assessment Scale, SmithKline Beecham Quality of Life Scale, respectively. Results:The long term group had significantly lower total PANSS score and PANSS negative subscale score than both the short term group and no job group. The long term group had significantly higher SOFAS score than the other two groups. The long term group had significantly lower PANSS positive subscale score, PANSS general psychopathology subscale score and CGI score than the short term group. Conclusion:The long term group was significantly different from both the short term group and no job group in symptomatology and social functioning. There was no significant difference between the short term group and no job group.

Purpose: In developing new products, reducing performance variation is important for competitiveness factors such as quality, cost, and delivery. This paper aims at evaluating three performance variations; measurement,performance evaluation, and manufacturing variations, and then improving product and process design, focused on paper helicopter making case study.Methods: For measurement system analysis, gage R&R (repeatability and reproducibility), linearity, stability are evaluated. Since gage R&R are not satisfactory, the measurement system is improved by adopting voice memos application of iPhone and providing standard measurement procedure. To evaluate performance variation,product deterioration and environment factor (wind speed) is considered. Since the existing design is sensitive to these noise factors, a new product design is developed, which is proven to be robust to the noise factors. Finally, manufacturing variations are evaluated with five factors which can cause variation in flight time. To reduce the impact of three significant factors, three improvement methods are applied.Results: Three performance variations are evaluated and robust paper helicopter design is presented.Conclusion: To reduce measurement and process variations, improved measurement method and paper helicopter making procedure are proposed. A new product design is also presented which is robust to deterioration and environmental variation. This paper is expected to benefit students and practitioners who want to have hands-on knowledge on new product quality improvement.
