        李金永,田寬培 全北大學校 1975 論文集 Vol.17 No.-

        1. As the children become of an age, it is expected that it is the chief reason of the diet problems that the development of the physical standard is good, in order of the nursery school children, home children and joint lodging children. Therefore in order that we increase the national power by means of the development of physical standard of all the people, and we keep higher health, it is desired that the authorities concerned or the managers of nursery schools must pay attention to dietary lives of the nursery school children. 2. Though the personal experditure is put in a little more, as a policy of decreasing the young boys and girls' criminal genesis rate, and of clearing up their frustration, it is requested urgently that the recreation facilities of the nursery school must completely be equipped and the teachers of the nursery school must be increased. 3. In our families the parents of each family will have to improve their children's dietary lives with nutritious foods no less than the sports middle school principal or the manager of nursery school. On the other hand, it is required, for references, that we must reexamine the menu of joint boarding students so as to be more good one. To conclude, exceptiong the joint boarding students, in order to improve the children in our families, especially the nursery school children's health, and physical standard, to plan the increasing of the national power, to prevent juvenile crime, and to construct a bright welfare society, first of all it is expected that we must achieve, it is source, increasing of the gross national income urgently.

        시설노인의 자아존중감과 우울

        박금자,이지현,배경의,강양희,송후승 노인간호학회 2007 노인간호학회지 Vol.9 No.1

        Purpose: The purpose of this study was to identify levels of self-esteem and depression in the elders who are residents in welfare facilities and to provide basic data for developing nursing intervention programs for these people. Methods: The participants in this study were 192 older people who scored 24 or higher on the K-MMSE (Korean-Mini Mental State Examination), and have lived for three months or more in one of 4 institutions located in B Metropolitan City. The data were collected by structured questionnaire from August 1 to 20 2006 and frequency, percentage, mean and standard deviation, and Pearson correlation coefficient were used to analyze the data with the SPSS/12.0 program. Results: 1. The score for self-esteem of the participants was 33.70± 7.20 (tool range: 10-50), and for depression, 6.57±3.98 (tool range: 0-15). 2. There was a slightly negative correlation between self-esteem and depression (r=-.388, p=.000). 3. There were significant differences in self-esteem according to education level (F=4.486, p= .012), and level of intention to be admitted to facility (F=7.504, p=-.000). 4. There was significant difference in depression according to education level (F=3.832, p=.023), type of religion (F=3.837, p= .005), level of intention to be admitted to facility (F=7.987, p=.000). Conclusion: This study might help in developing nursing intervention programs to improve self-esteem and reduce depression these elders.

      • SFC를 이용한 프로그래머블 로직 콘트롤러 프로그래밍

        오금곤,조금배,박병강 조선대학교 동력자원연구소 1993 動力資源硏究所誌 Vol.15 No.1

        PLC system is used for the purpose of decentralized control and allows data transmission between programable controllers to be easily performed by using an exclusive relay area. The programming language is important to operate the system. In this paper, it is used SFC(Sequence Function Cahrt) programming language to decrease the execution time with compare the ladder diagram program method. As a result, the SFC programming language process time is faster about 20∼30(%) than the ladder diagram programming.

      • 자기진단형 위상제어에 의한 단상유도전동기의 특성 및 모니터링 시스템에 관한 연구

        조금배,박수강,백형래,임양수,이성길 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.2

        The three-phase induction motor is rugged, reliable, long-lived, self-starting, smooth-running. But it is relatively inexpensive and three-phase power in not available everywhere, so if possible we need single-phase motor with the same characteristics. In fact, single-phase induction motors have excellent characteristics and outnumber the three-phase variety. Most of the small electric motors used in home, farm, or office are single-phase induction motors of one type or another. This electric motors application field need most energy saving type drive according to enlargement of electronic goods and to tend high class. The paper is proposed a various phase control methods for energy saving of single- phase induction motor. The controllers that are embodied by each method can use by various usage according to each performance and it is considered that application may help in the electrical energy saving because is possible to other electrical appliances.

      • DC/DC 컨버터의 주기배화 분기특성에 관한 연구

        정삼용,조금배 조선대학교 에너지.자원신기술연구소 1999 에너지·자원신기술연구소 논문지 Vol.21 No.2

        In this paper, author describe the simulation results concerning the period doubling bifurcation route to chaos of DC/DC boost converter under current mode control to show that it is common phenomena on switching regulator when parameters are improperly chosen or continuously varied beyond the ensured region by system designer. The Bifurcation diagrams of periodic orbits of inductor current and capacitor voltage of DC/DC boost converter are plotted with sampled data at moment of each clock pulse causing switching on. DC/DC boost converter studied on this paper is modelled by its state space equations as per switching condition under continuous conduction mode. Current reference signal and capacitance are chosen as the bifurcation parameters and those are varied in step for iterative calculation to find the bifurcation points of periodic orbits of state variables.

        최창주,오금곤,조금배 조선대학교 동력자원연구소 1996 動力資源硏究所誌 Vol.18 No.1

        Recently, the environmental load has rapidly increased with the burgeoning of world population and the great expansion of severe global environmental issues. Therfore, it is inevitable to develop technology to ensure a stable clean energy source to replace oil as well as energy saving technology. Under these circumstances, photovoltaics (elecric power generation directly from sun light using solar cell) have attracted world-wide attention because of its cleaness. This paper reviews photovoltaic measurements on the refernce conditions and reference cell mothod and studies photovoltaic devices on the performance measurement and evalution procedures. Especially, activation of the photovoltaic researches and industrialization are emphasized in this paper.

      • 초음파 모터의 위상차 조절과 위상차-주파수 다중 조절에 따른 속도 특성

        김동옥,김원배,오금곤,최한수,김영동 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.2

        To control the position, velocity and torque of the ultrasonic motor, a great variety of method are proposed such as the amplitude, phase difference, frequency and so on. In the case of phase difference method, it has some advantages; it can control the direction and velocity of rotation only adjusting the phase difference and it has wide control-band. During the USM driving on adjusting phase difference, its characteristic was transformed by the change of resonance-frequency of stator, which means that the resonance frequency is different according to the phase difference. Consequently, we need to set up the most suitable driving frequency according to each phase difference.

      • 태양전지의 최대 출력제어의 특성해석

        백형래,조금배,유권종 조선대학교 동력자원연구소 1993 動力資源硏究所誌 Vol.15 No.2

        In the photovoltaic power system the maximum power control is necessary because output power of solar cell array is varied by solar insolation and temperature. The high frequency operation is essential for the development of the controller. However the e-i characteristics of Solar Cell Array have hysteresis in high frequency operation. It makes controller which is operated by conventional control method uncontrollable. Therefore, it is indispensable to develop a new control method to obtain maximum available power from solar cell array. The simulation result shows the effectiveness of controller using two-state value control method.
