Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

구형함수에 의한 단상 ICB 회로 해석

洪淳瓚 단국대학교 1988 論文集 Vol.22 No.-

This paper presents a new analysis method for rhe single phase ICB circuit, which belong to a new group of converters. Unlike the SFC, S^4LCL, DFC and other circuits which have time varying switching intervals for a constant time-averaged value of coil voltage, the ICB circuits operate with a clock-drived sequence of gate pulses which have constant switching intervals. This new method is a specialized method of analysis for calculating the dynamic functions of the ICB and the computational difficulties of the infinite Fourier series can be avoided. At first, quadrometric functions are newly defined in terms of the superposition of several unit step functions, and then single phase ICB circuit is analyzed by newly defined square function. By comparison with the Fourier resullt, it is verified that the analysis by means of square functions is more accurate and simple.

마이크로프로세서에 의한 직류전동기의 고효율 운전해석

This paper describes a method to analyze the drive system which can improve the efficiency of dc motors. It is derived that the ratio of the armature current and the field current should be maintained constant to maximize the efficiency at a specified speed. The real time control is implemented by using a microprocessor. To increase the efficiency, the flux should be reduced. Reducing the flux may cause undesirable dynamic responses. In order to investigate the dynamic characteristics, the system equation is derived which consists of three equations of the dc motor and two equations of the controllers. Because the system equation is nonlinear, the small signal linearization is used. As the system is controlled by the microprocessor, the linearized system equation should be transformed into the difference equation. Based on this system equation, computer simulations are carried out. As a result, the dynamic response is satisfactory regardless of reducing the airgap flux.

삼상 ICB회로의 설계기준에 관한 연구

洪淳瓚 단국대학교 1992 論文集 Vol.26 No.-

This paper deals with the design criteria of the three-phase ICB(Inductor Converter Bridge) circuit for phase difference control. To determine the voltage ratings of capacitors and thyristors, the peak values of voltage across the elements were derived as the function of related parameters and were analyzed for all the range of phase difference between the two converters. Also, the capacitance of capacitors was estimated and the current ratings and turn-off time of thyristors were analyzed. Finally, a three-phase ICB circuit was designed as an example. In the example, the loads were two superconductive coils with inductance L_s=L_L=L=0.422 [H] and stored energy E=0.5 [MJ] The resulting values in this paper are gheoretical values. Therefore, for the stability of practical system, it is necessary that the turn-off time is shorter than the theoretical value and the ratings of voltage and current should have 50 [%] margin.

洪淳瓚 단국대학교 1989 論文集 Vol.23 No.-

In this paper, the time-averaged behavior of the three-phase ICB(Inductor-Converter-Bridge) circuit has been analyzed by using the state-space averaging method. The results are in closed form far from the results obtained by using the Fourter series. Therefore, the computational difficulties of the infinite Fourier series can be avoided and the results derived in this paper are available especially in real time control. Also, it was verified that the analysis by means of state space averaging method was more accurate and simple by comparison with the Fourier results. Unlike the SFC, S^4LCL, DFC and other circuits which have time varying switching intervals for a constant time-averaged value of coil voltage, the ICB circuits operate with a clock-driven sequence of gate pulses which have constant switching intervals.

Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

We investigated the effects of nano-silica on the kinetic and film properties of UV curable coatings. Coating properties such as hardness, gloss, chemical and stain resistances and adhesion of the UV cured films containing various concentration of nano-silica were investigated. The matting, pencil hardness, chemical resistance, and abrasion resistances were apparently improved Via addition of nano-silica. Pendulum hardness was also enhanced with the increasing content of nano-silica up to 5 weight percent. However, the pendulum hardness and the adhesion decreased as nano-silica content increased above 10 weight percent. DPC analysis revealed that the presence of nano-silica in UV curable coating formulation enhanced photo curing. It was demonstrated that hardness. abrasion resistance, and chemical resistance of UV cured film can be increased without loss of optical properties through nanocomposite.

電子計算機에 의한 半導體回路의 解析

洪淳瓚 단국대학교 1980 論文集 Vol.14 No.-

In the earlier papers published on digital computation of semiconductor circuits, the different equivalent circuits that arise during the operation of the circuit were assumed. The differential equation corresponding to individual modes of operation were set up and can only applied to special circuits. In order to overcome the disadvantage, the method based on network topology was developed. In this method, the thyristors and the diodes are assumed to represent open circuit when they are off and a small resistance when they are on. The assumption requires a change in the topology of the original network from mode to mode. This paper deals with the computer aided analysis method for semiconductor circuit which rejects the disadvantage. The method is based on network topogy and semiconductors are considered as resistance elements which have different resistance depending on its mode. The advantage of this method is that the incidence matrix doesn't need to reconstruct regardless of mode change and the loop calculation is reduced in the program. As an example, this is applied to a single-phase full-wave controlled rectifier circuit with an RL load and the fow charts and the computed results are presented.

PWM인버터회로에서의 손실분석

洪淳瓚,金鍾九 단국대학교 1995 論文集 Vol.29 No.-

This paper deals with loss analysis in inverter circuits controlled by pulse width modulation method. The loss in inverter circuits may be produced in active switching elements, passive switching elements, and snubber circuit. The losses in active switching elements are classified into the conduction losses and switching losses, and can be reduced by the selection of elements with low saturation voltage and short turn-on/turn-off times. There are also conduction losses and switching losses in passive switching elements and these losses can be reduced by selecting the fast recovery diode with low forward voltage drop and short reverse recovery time. The loss in snubber circuit is relatively small and can be ignored. As an example, the loss calculation and analysis are carried out in the prototype three-phase VSI(Voltage Source Inverter) for electric vehicles.

특성이 다른 스위치를 병렬로 사용한 반브리지 변환기의 손실 분석

홍순찬 단국대학교 1998 論文集 Vol.33 No.-

Due to high power ratings and low conduction loss, IGBTs are becoming the switching devices of choice in most new applications. However, the switching speed is slower than that of MOSFETs and thus high switching loss causes the switching frequency limination of converters. One method to solve such a problem is to use a IGBT-MOSFET parallel switch. In a parallel switch, each of IGBT and MOSFET plays dominantly during on-periods and switching intervals, respectively. This paper deals with the loss analysis of a half-bridge dc-dc converter which has low output voltage characteristics for commutation facilities. Parallel switches which are composed of the IGBT and MOSFET with different characteristics are sued to reduce the switching loss and conduction loss. Loss equations are derived by using a linearized model and the operation of the converter is investigated by simulations.
