SRM은 이중 돌극 구조의 전동기로 전기자만 존재하는 전동기이다. 동기기 혹은 유도기와 같이 전기자와 계자가 구분되는 전동기는 단순한 수학적 모델을 이용해 특성 해석이 비교적 용이한 반면 SRM의 경우는 단순한 수학적 모델을 적용하기 힘들며 이 때문에 특성 해석 및 설계가 상대적으로 어렵다. 통상 SRM의 설계는 구동 회로를 포함한 수치 해석기반 특성 해석 결과를 기반으로 반복 수행을 통해 이루어진다. 이 과정에서 설계 인자의 변화에 따른 경향 분석이 필요하며 수많은 설계 인자들은 서로 영향을 미치게 된다. 설계 시간을 단축하고 정확한 설계를 위해서는 설계 주요 인자를 기반으로 한 모델링 기법이 필요하다. 이를 위해 본 논문에서는 SRM의 주요 설계 인자의 수를 최소화 하여 형상 모델링을 할 수 있게 수식을 정리하였으며, 이를 이용해 SRM을 설계하기 위한 방법론을 제시하였다. 특히, 그동안 많이 연구 된 6/4극 모델에 대한 설계 기법을 제안하고 제안한 기법에 의한 설계의 예를 보였다. SRMs are difficult to design using a simple mathematical model and, consequently, numerical analysis based characteristics analysis is used including drive circuits. In this process, it is necessary to analyze the trends according to the change of the design factors, however, many of the design factors affect each other. In order to shorten the design time and achieve a proper design, a modeling technique based on the design parameters is needed. For this purpose, this paper summarizes the formulas employed for shape modeling by minimizing the number of major design factors of the SRM, and proposes a methodology for SRM design using these formulas. In particular, we propose a design method for a 6/4-pole model, one which has been studied for a long time, and showed an example of a design produced by the proposed method.

In almost all countries, older adults present higher suicide rates than young peo-ple and generally, lifetime suicide risk and the wish to die are positively correlated with increase in age. In Korea, the number of the population in the elderly has been increased more rapidly than other age groups. Through analyzing the officially reported suicidal statistics, we found that the rates and number of elderly suicide in Korea have been increased since 1985, and suicide was most prevalent among 'old and old' and tended to be more prevalent among men, like western world. Some studies about the elderly suicide were reviewed. A community survey reported that 14.6% of the elderly aged 65 years and over in rural area had repeated feelings that they wanted to die during the previous 2 weeks, and the significant associated factors with the wish to die were depressive disorder, age 85 and over, and poor economical status. But there have been a few studies about the elderly suicide, suicide attempt and death thought in Korea. The needs to understand suicide among the elderly is becoming more urgent and should generate more research. Knowledge of the conditions leading to suicide will aid clinicians and public policy makers by facilitating the effective development of intervention and prevention programs.

Vibrations on industrial generators can be divided into electromagnetic, mechanical and aerodynamic vibration. Among them, the electromagnetic vibration is produced by combination of natural frequency and harmonics of magnetic flux, so it is relatively hard to predict the electromagnetic vibration. In this paper, we developed 1-way coupled (magnetic, stiffness) analysis technology to evaluate characteristics of the vibration induced by electromagnetic field. With the analysis, we investigated the forced vibration characteristics considering radial magnetic force, which was calculated from the magnetic analysis, on stator core teeth of the generator. And structure design reducing the electromagnetic vibration of the generator was suggested from the analysis results.

The efficacy of fluoxetine was evaluated in 32 patients with major depression in double-blind amitriptyline-controlled clinical trials. Patients were randomly assigned to 6 weeks of treatment with 20mg/day of fluoxetine and 25-100mg/day of amitriptyline. We used the Hamilton rating scale for depression(HAM-D) and the Clinical Global Improvement(CGI) to evaluate the improvement of depression. In addition, we also used the Covi Anxiety Scale and the Anxiety/Somatization subscale of HAM-D to investigate the relieving effect of anxiety. The improvement by fluoxetine in mean total score of HAM-D and CGI was comparable to amitriptyline. Fluoxetine also reduced anxiety significantly, but there was no difference between fluoxetine and amitriptyline in relieving anxiety symptoms. Fluoxetine showed considerably less adverse effects, especially anticholinergic effect and weight gain than amitriptyline. In conclusion, 20mg/day of fluoxetine was sufficiently effective in the treatment of depressive patients and was better tolerated than amitriptyline.

Distribution of Permanent magnet used in the spindle motor on the ODD is arranged by magnetizer. In general, permanent magnet is pulled between yoke and back yoke of magnetizer so that symmetric magnetization distribution. But the magnet has unsymmctric magnetization distribution because of eccentricity of the yoke in mass production. So, in this paper we discuss the effect of asymmetric magnetization distribution on back EMF and cogging torque of the spindle motor.

Objectives : This study was performed to evaluate the status of psychiatric consultation at a newly opened university hospital, to explore problems related to psychiatric consultation and to contribute for future consultation to be more systematic and more efficient. Methods: The subjects of this study were 284 patients hospitalized at Inha University Hospital between September 1, 1996 and August 31, 1997, who were referred for psychiatric consultation during hospitalization. This study was evaluated demographical characteristics of referred patients, resons for referral, recommendations by psychiatric consultant, clinical diagnoses, psychiatric diagnoses, relationship between referral time and hospitalization following the day of consultation and consultation referral types based upon psychiatrists' reports and patients' medical charts. Results : Most common patients referred to consultation were females aged 20s who visited at the department of internal medicine and related to the risk of suicidal attempts. Mood disorder was the most frequent psychiatric diagnosis, and the most common recommendations were to use psychopharmacological treatment along with outpatient visits. The 30% of subjects were referred to consultation within a day after hospitalization. In the case of consultation referral timing within two days and after three days, there was significant difference between early consultation and shorter hospitalization following the day of consultation. Most frequent type of consultation(29.6%) was categorized as IIIa type(physical complication type as a "Mending" request type). Conclusion : In review of consultation referral timing and consultation referral type of the subjects, who were referred for psychiatric consultation for one year at a newly opened University Hospital, referrals were found to be made within two days after their admission to hospital(50.7%), which was observed to be early request. We found that there was significant association between early consultation and shorter hospitalization following the day of consultation. The physical complication type(29.6%) which belongs to "Mending" request type was found to be the most frequent consultation referral type. This result indicates that more systematic psychiatric consultation is needed for the future.
