Purpose: This study aims to analyze the difference in the perception that nursing students and medical students have regarding the image of nurses. Method: The sampling group for this study was made up of 111 nursing students and 117 medicine students, conducted from the 19th August 2013 to 3rd September 2013. The tool used for this study is the “Nurse Image Scale”. The data is analyzed using the SPSS 21.0 program, technical stats, t-test and ANOVA with Scheffe test. Result: There was a notable difference in the results(t=6.94, p<001), with the average image perception score of nurses at 3.84±0.34 amongst nursing students being higher than the 3.50±0.38 amongst Medicine students. The average score of the 4 areas tested, “Qualification of a Nurse”, “Role of a Nurse”, “Social Participation of a Nurse” and “Interpersonal Skills of a Nurse” were all marked higher by the nursing students than the medicine students. The average score became notably higher as the period of practice became shorter with nursing students (F=4.21, p=.043). Furthermore, the average score for the “Qualification of a Nurse” was notably higher as the period of practice became shorter (F=3.98, p=.049). Medical students gave an average score for the “Qualification of a Nurse”(F=3.72, p=.027) and the “Interpersonal Skills of a Nurse”(F=4.11, p=.019) which was relative to the development of a nurse’s image, while the average score for the “Role of a Nurse” was notably higher with a longer period of practice(F=6.65, p=.011). Conclusion: The results of this study suggest that the image perception of a nurse can vary depending on the experience in period of practice. Therefore, together with this study conducted with nursing students and medicine students, there is a need for further studies conducted on image perception of nurses with various experience in period of practice.

Purposes :The purposes of this study was to investigate the self-managing status according to the life styles and the diabetic knowledge of early adulthood. The subjects in this study were 240people, the early adult aged twenties to thirties living in the metropolitan area. Data were collected by using self-administered questionnaires that measure about the knowledge of diabetes; the dietetic behavior; the knowledge of diet; the exercise behavior; the knowledge of exercise. Descriptive statistics, t-test, ANOVA, and correlation were used for data analysis. Result :1. At the knowledge of diabetes degree based on the general character, the subjects who had experiences of diabetic education have higher degree of the diabetic knowledge. 2. At the knowledge of diabetes degree according to the life style, the subjects who have regular diet are appeared highly. Also the subjects who don't take much food of animal origin have higher degree. 3. At the knowledge of diet based on the life style, the subjects who don't keep three times meals a day are appeared highly. Also the subjects who have regular diet have higher degree. 4. At the knowledge of exercise according to the life style, the subjects who take extra nutritions 3-4 times a week are appeared highly. Although the subjects tend to know about dietary, exercise and health management, it showed that they actually don't perform what they know in their everyday of life. The reason for this could be the lack of perceived seriousness about diabetes mellitus. Thus as nursing professionals, we should provide them proper health education and support. Moreover, advanced research on the empowerment is warranted.

Y/Gd-free yellow Lu₃Al₅O₁₂:Ce³⁺ phosphor for white LEDs

Park, K.,Kim, T.,Yu, Y.,Seo, K.,Kim, J. Elsevier [etc.] 2016 Journal of luminescence Vol.173 No.-

<P>Solid solubility limit of Ce3+ ions into Lu-based garnet, Lu3(1-x)Ce3xAl5O12, was determined as below 6.7 mol% (3x < 0.2 mol) through Raman spectra and X-ray diffraction patterns. Above the solid solubility limit (3x >= 0.2 mol), Lu3((1-x))Ce(3x)Al(5)O(12) phosphors showed the significant redshift to the yellow spectral region without Y3+ and Gd3+ ions. The redshift was explained in terms of the local compressive strain at the Ce3+ sites. The optimized sample (3x=0.4 mol) had a dominant emission wavelength of 548 nm, color coordinate of CIEx=0.421, CIEy=0.548, quantum efficiency of 80%, absorbance of 91%, lumen maintenance of 90% and high color stability at 473 K under 450 nm excitation wavelength, suggesting substitutability for the commercial yellow (Y, Gd)(3)(Al, Ga)(5)O-12:Ce3+ phosphor. The measured decay times at higher Ce3+ concentration are significantly shortened at higher temperature than that of those at lower Ce3+ concentration. The yellow Lu2.6Ce0.4Al5O12 and a commercial red (Sr, Ca)AlSiN3:Eu2+ phosphor were applied to the pc-WLED, it gave an excellent luminous efficiency (138 lm/W) with a slightly lower color rendering index (Ra =76.4) under correlated color temperature of 6500 K compared to those of the (Y, Gd)(3)(Al, Ga)(5)O-12:Ce3+-based one (136 lm/W, Ra =78.7). Especially, the quantities of the used phosphors were significantly decreased by 20% for the yellow LuAG:Ce and by 40% for the red (Sr, Ca)AlSiN3:Eu2+. Thus, the Y/Gd-free pure LuAG:Ce yellow phosphors can be used as alternative to the commercial yellow YAG:Ce phosphor. (C) 2016 Elsevier B.V. All rights reserved.</P>

In nuclear power plant, the reactor cooling system has maintained high-Reynolds-number flow above 1E+07 to cool a heat generated by the reactor. To minimize uncertainty for flow calibration, it is necessary to install a flow simulation system to maintain the high-Reynolds-number flow. Y-connection is selected to connect four (4) parallel high flow circulation pumps for minimizing system pressure loss. This paper describes the characteristics for Y-connection by computer flow simulation. It was confirmed through the results that the pressure loss of the Y-connection was lower than that of T-connection, and that the pressure loss of the connection was similar sixty degree (60°) and below of connection angle.

In a trial involving 120 pigs, the effects of transport time on blood profile and meat quality in pigs were investigated. One group of 60 animals was subjected to 20min and the others to 2 h transport time, and held in lairage for 1 h 30min. There was not significantly different in the carcass weight, backfat thickness and carcass grade between groups. Cortisol and lactic dehydrogenase(LDH) concentrations were significantly(P<0.05) higher in the group transported for 2 h compared with the group transported for 20min. There was not significantly different(P>0.05) in meat quality(?_(1), ?_(u), drip loss, cooking loss, hardness, CIE L^(*), a^(*), b^9*) and NPPC) and skin damage of port carcass between groups. These results imply that the stress could be affected by transport time in transit without meat quality.

To date many approaches to the pipe line have been suggested on the basis of no viscosity and without consideration of pressure loss due to the friction of fluid inside pipe line. Also, many researches have been performed assuming that the slope of velocity by viscosity is in direction of flow, while velocity is constant in the cross section pipe line. The present work purports to study both experimentally and analytically the transient response characteristics of unsteady laminar flow of a pipe line. The transfer function for the pressure wave is derived for the case of a pipe line having relatively small diameter. The effect of viscosity is included at the derivation. The transient response characteristics predicted by the analytical result are compared with the experimental results. The pulsating flow is generated by the ball valve and speed controler equipped D.C. motor, the characteristics of the pulsating laminar flow in a pipe are measured by the pressure transducer and the oscilloscope. The experimental results indicate that the analytical derivation is adequate the experimental data compare favorably with the analysis.

Purpose: The purpose of this study was to determine the relationship among empathy ability, communication ability, and psychological burnout in nursing students on clinical practice. Method: Data was collected using questionnaires between September 20th, 2017 to January 2th, 2018. Participants of this study were 159 of grade 3 and 4 nursing students who had completed at least one semester of clinical practice experience and currently attending universities located in Seoul. Data were analyzed using percentage, average, standard deviation, t-test, one-way ANOVA, Scheffe’s test and Pearson’s correlation coefficient using the SPSS WIN 24.0 program. Results: The empathy ability was positively correlated with communication ability(r=.437, p=.000). And the communication ability was negatively correlated with psychological burnout(r=-.390, p=.000). Also the empathy ability was negatively correlated with psychological burnout(r=-217, p=.006). Conclusion: These results suggest that psychological burnout is closely related to empathy ability and communication ability. Based on these results, empathy ability and communication ability need to be increased by efficient management and intervention to decrease the degree of psychological burnout in nursing students. Also, the findings should be considered when developing plans or education programs for nursing students’ major adjustment.

Purpose: The purpose of this study was to provide basic data for use in the upgrade of healthcare for the elderly and to provide guidance toward educating the elderly in the proper use of medications by determining the level of drug knowledge, current use, and adherence by the elderly. Method: The participants of this study were selected using the convenient sampling method. Participants of this study comprised of 160 elderly who were aged 65 or older, who were participants to the elderly municipal welfare center in Seoul. The instrument used for this study was a structured questionnaire (Han,2011). Collected data were analyzed using the SPSS20.0 program with descriptive statistics, t-test, ANOVA, and Pearson’s correlation coefficient. Result: The mean score for drug knowledge was 7.6±2.9 and drug misuse was 4.7±2.8. There were significant differences about drug knowledge according to the following: level of education (F=8.053 p=.000), and spouse (t=2.14 p=.034). There were significant differences between drug misuse and monthly income (F=2.167 p=.040). There was no statistically significant relationship between drug knowledge and drug misuse (r=-.087, p=.271). Conclusion: A replication study based on broader region and in-depth research is needed. The development of the customized education protocol considering various levels of education, income, spouse and physical condition are needed. Further research is suggested to find out the status of medication education for the elderly by nurses.
