The performance test apparatus of liquid-phase plate heat exchanger was installed and the computer program for design was developed in this study. The detail temperature distribution of hot and cold fluids in each path of heat exchanger was calculated by numerical method and the correlation for the heat transfer coefficient was defined. The heat transfer coefficients were measured using the working fluids of water and glycerine to investigate the effect of fluid viscosity. The measured heat transfer coefficients were compared with the calculated values obtained from the computer program and it was shown that error of the calculated values was generally less than 5%.

University Research Centers specialized in defense technology(DURCs) were designed to develop fundamental knowledge and to acquire core technologies related to defense development by conducting creative and interdisciplinary research. The centers also have a function of fostering scientists and practitioners possessing defense-oriented cross-disciplinary knowledges. Since the outset of the DURC in 1994, Sixteen DURCs have been funded and eleven DURCs are now in operation. The purpose of this paper is to analyse the operational status and the performance of DURCs and to suggest ideas on improving the effectiveness of the DURC program by comparing with the Korea Excellent Research Center program and the U.S. National Science Foundation(NSF) Engineering Research Center(ERC) program.

Developed is a computer program for the prediction of the aero-acoustic performance characteristics such as discharge pressure, efficiency, power and noise level in the basic design step of axial flow fan. The flow field and the aerodynamic performance of fan are analyzed by using the streamline curvature computing scheme with total pressure loss and flow deviation models. Fan noise is assumed to be generated due to the pressure fluctuations induced by wake vortices of fan blades and to radiate via dipole distribution. The vortex-induced fluctuating pressure on blade surface is calculated by combining thin airfoil theory and the predicted flow field data. The predicted aerodynamic performances, sound pressure level and noise directivity patterns of fan by the present computer program are favorably compared with the test data of actual fan. Furthermore, the present computer program is shown to be very useful in optimizing design variables of fan with high efficiency and low noise level and in analyzing their design sensitivities.

Purpose : This study develop a Video Recording-Based Standardized Handoff (VRSH) program at shift change for ward nurses. Methods : The study was conducted in five medical, three surgical, and one comprehensive nursing care service wards affiliated with a secondary general hospital. In this methodological study, the VRSH program was developed between April and December, 2017. It is noted that 65 nurses who were involved in the VRSH program participated in this study. Results : In line with the modified Situation, Background, Assessment, Recommendation tool, the VRSH program consisted of three phases. In the VRSH program, the average time for handoff duration was 3-5 minutes per patient. More than 90% of the ward nurses were satisfied with the VRSH program since it benefited them by reducing overtime work and improving the performance, as well as effective communication, of nurses. The content analysis of nurses' VRSH program experience, revealed three categories and eight sub-categories. Conclusions : This study provides evidence that the VRSH program improves effective nursing performance and, the handoff communication and relationships between nurses. Future studies on large sample sizes and multiple settings are required to substantially evaluate the impact of the VRSH program on clinical outcomes.

A performance simulation program for the turboprop engine (PT6A-62), which is the power plant of the first Korean indigenous basic trainer KT-1, was developed for performance prediction, development of an EHMS (Engine Health Monitoring System) and the flight simulator. Characteristics of components including compressors, turbines, power turbines and the constant speed propeller were required for the steady state and transient performance analysis with on and off design point analysis. In most cases, these were substituted for what scaled from similar engine components'characteristics with the scaling law. The developed program was evaluated with the performance data provided by the engine manufacturer and with analysis results of GASTURB program, which is well known for the performance simulation of gas turbines. Performance parameters such as mass flow rate, compressor pressure ratio, fuel flow rate, specific fuel consumption and turbine inlet temperature were discussed to evaluate validity of the developed program at various cases. The first case was the sea level static standard condition and other cases were considered with various altitudes, flight velocities and part loads with the range between idle and 105% rotational speed of the gas generator. In the transient analysis, the Continuity of Mass Flow Method was utilized under the condition that mass stored between components is ignored and the flow compatibility is satisfied, and the Modified Euler Method was used for integration of the surplus torque. The transient performance analysis for various fuel schedules was performed. When the fuel step increase was considered, the overshoot of the turbine inlet temperature occurred. However, in case of ramp increase of the fuel longer than step increase of the fuel, the overshoot of the turbine inlet temperature was effectively reduced.

Uniformity and performance characteristics of LTPS TFTs are important parameters for making advanced active-matrix displays. In this paper, we describe an SLS-based crystallization approach for producing orientation-controlled Si films with reduced concentrations of planar defects that stand to potentially deliver unprecedented levels of device uniformity and performance. Specifically, a 2-step process referred to as hybrid SLS has been developed that produces a variety of high-quality {100} surface-oriented Si films.

Purpose: This study was conducted to develop and evaluate the effectiveness of a prenatal parental role education program. Methods: The participants were healthy primiparous women and their healthy newborn babies. 57 mother-infant diads(27 in the intervention group, 30 in the control group). For the intervention group, an additional 4 prenatal parental role education programs and 2 postnatal telephone calls(1st & 3rd week after birth) were provided. Data were analyzed by frequency, chi-square test, t-test and repeated measures ANOVA using SPSS PC+ 10.0 program. Results: Significant differences were found in self-confidence in maternal role performance, mother-infant interaction and infant physical growth between the two groups. This result indicate that the intervention program was effective in improving self-confidence in maternal role performance, mother-infant interaction and in facilitating infant physical growth. Conclusions: The prenatal parental role education program developed by the author was a very effective program in promoting maternal self-confidence, mother-infant interaction, and fostering infant's physical growth at 4 weeks after infant's birth.

The risk management is an organized method for identifying and measuring risk and for selecting, developing, and implementing options for the handling of risk. The risk management covers all programatic and technical factors which affect the system development performance, cost, and schedule. While technical issues are primary concern for systems engineering, the three elements(performance, cost, and schedule) must be balanced for a successful risk management process. This paper proposes the risk management process for the KSLV-I(Korea Space Launch Vehicle-I) program using computer-aided systems engineering tool, Cradle. The risk management process of KSLV-I program is similar to the general risk management process, but it has its own specific features to manage large-scale complex characteristics of KSLV-I program.
