This study was conducted to investigate the impact of emotional intelligence according to the level of interpersonal relation competence. For the study, data were collected from 126 students in the department of nursing at a university located in B city from November 29 to December 16, 2019, and data were analyzed by Anova and Regression analysis. The interpersonal relation competence of nursing students was classified into less than 60 and 60 or more. In the group with an average of less than 60 in interpersonal relation competence. nursing students' self-emotional expression and control of others were significant positive effecting factors for interpersonal relation competence(explanatory power, 22.5%). In the group with an average of 60 or more in interpersonal relationship competence, self-emotional expression and Motivation were significant effecting factors(explanatory power 33.6%). According to the results of this study, we propose an individual approach according to their level of interpersonal relation competence for nursing education to improve the interpersonal relation competence abilities of nursing students.

The pilot tidal current power plant is to be constructed at the Uldolmok between Chindo and Haenam, during next year. and extensive coastal engineering research works have been carried out. In this paper we describes some observation results of the tide and tidal current. as well as modeling work in order to investigate the tide and tidal current regime change in relation to the tidal current power plant (TCPP) construction. The special modeling skill in order to consider the turbine operation in the TCPP is developed and applied to the estimation for the flow regime change by the simple layout of the tidal current power plant.

The dispersion relation and the characteristic of propagation are measured. The measurements of the dispersion relation are observed by a plunger method employed in slow plasma density by pumping microwaves on the axis are observed in plasma loaded slow wave structure. In case of small incident microwave powers the well known plasma density cavity are observed. At the axial positions of minimal radius in the waveguides, the maxima og the electron density, the plasma potential and the RF electric field are observed in cases of high-power microwaves.

In this paper the recent studies of digital governor for the Diesel Engine in Korea is summarized and that of usage in the marine and land field as of power plant is analyzed for the interest and development of the enterprise with relation with relation to this industrial part. Our investigation shows that until now the studies on the digitl governor are mainly carried out in KMU and land usage for the power plants is increased gradually because reliance of digital governor is improved and system for the maneuvering and monitoring the plants is computerized.

Fossil power plant availability is significantly affected by gradual degradations of equipment as operation of the plant continues. It is quite important to determine whether or not to replace some equipment and when to replace the equipment. Performance calculation and analysis can provide the information. Robustness in the performance calculation can be increased by using verification ＆ validation of measured input data. We suggest new algorithm in which estimation relation for validated measurement can be obtained using correlation between measurements. Input estimation model is obtained using design data and acceptance measurement data of domestic 16 fossil power plant. The model consists of finding mostly correlated state variable in plant state and mapping relation based on the model and current state of power plant.

The purpose of this study was to investigate the degree of father's participation on child-rearing in relation to parents' sex-role streotypes and conjugal power structure and backg-round factors(children's sex paternal aged and educational level. maternal employment status and family's socio-economic status) The subjects of the study 368 couples who have preschoolers. The main study was conducted from sep. 17 to Oct. 2. 1992 using a set of questionaires which has been revised after a pilot study of 38 couples Statistical method for data analysis were frequencies percentiles means ANOVA Duncan's multiple range test F-Test and Cronbach's a. The results indicated 1) That There were significant differences in the degree of father's participation on child-rearing in term of children's sex parternal age the parents' sex-role streotypes the type of conjugal power structure. 2) that the variables which have significant effects on the degree of father's participation of child-rearing were conjugal power structure mother's sex-role types and father's age.

Modern power grids are becoming more and more stressed with the load demands increasing continually. Therefore large stressed power systems exhibit complicated dynamic behavior when subjected to small disturbance. Especially, it is needed to analyze special conditions which make small signal stability structure varied according to operating conditions. This paper shows that the relation between small signal stability structure varied according to operating conditions. This paper shows that the relation between small signal stability and operating conditions can be identified well using node-focus point and 1:1 resonance point. Also, the weak point which limits operating range is found by the analysis of resonance condition, and it is shown that reactive power compensation may solve the problem in the weak points. The proposed method is applied to test systems, and the results illustrate its capabilities.

We have studied the possibility of global noise reduction by the sound power control through selection of distribution and impedance of absorptive materials. It is necessary to investigate the relation between the global sound energy in the field and the total sound power radiated by sources. In the previous work (1,2), the authors presented a useful design method to change boundary condition that can be useful to reduce noise in acoustically small enclosures. The possibility of total acoustic potential energy reduction by acoustic source power control is examined in an acoustically small cavity. Using acoustic energy balance equation, the relation between global noise control performance and absorptive material's arrangement/impedance is deduced. Numerical simulation is performed to interpret its physical meaning in terms of absorbent's distribution and impedance.

In this paper, the relation between displacement of piezoelectric material and electric field was proposed. FEA was introduced to predict the displacement and reaction force of plate spring attached in the piezoelectric material. The relation between displacement of piezoelectric material forced by plate spring and applied electric field were further verified by experimental investigation. Also, the flow rate of gas in piezoelectric valve was examined by experiment. Finally, the relation between electric field and gas flow was derived. Based on these results, these relations can be used in the design of mass flow controller.
