Purpose. We compared with the refracting power and aberration according to the measurement change in illumination and the pupils area by using the auto refraction instruments. Methods. In this study it were examined 64 eyes without eye disease, 21.4 (${\pm}2.54$) age, 32 (male 10, female 22) patients. Experiments in general illumination using the auto refraction instruments (HRK-8000A, Huvitz, Korea) was measured in both eyes 3 times and after scotopic for 30 minutes in a dark room blocked the light was measured in the same way. Aberration were measured coma, spherical aberration, high and low order aberrations in a general illumination (3500 lux) and low illumination (5 lux) of the pupil area 3.96 mm and 5.96 mm. Results. In the general illumination for measuring of the pupil area, the refractive power, coma, spherical aberration and low order aberration was no significant difference. In the low illumination, spherical aberration of the pupil area was $0.005({\pm}0.015){\mu}m$ in a 3.96mm, $0.014({\pm}0.020){\mu}m$ in a 5.96 mm and appeared a significant difference(p = 0.003). In general and low illumination on the results of comparing the measured values of the refractive power and aberration at the pupil area 3.96 mm, high order aberrations was $0.205({\pm}0.145){\mu}m$ in general illumination, $0.132({\pm}0.075){\mu}m$ in low illumination and appeared a significant differences(p = 0.001). High order aberrations at the pupil area 5.96 mm was $0.278({\pm}0.244){\mu}m$ in general illumination, $0.150({\pm}0.092){\mu}m$ in low illumination and appeared a significant differences(p = 0.000). Conclusions. When the eye refractive power measured by the automatic refraction does not depend on the illumination conditions and size of the observation pupil area, it was found that aberrations are affected by the illumination and the observation pupil area. It was found that the eye examination chamber illumination to obtain accurate measurement produces better results to decrease than to increase.

Purpose. This study pourpose to fashion lifestyle and color interests in accordance with group university students' lifestyle focused on students in health and nursing fields. Methods. This study administered a structured questionnaire to 321 random subjects who currently major in health and nursing fields and who reside in Daegu city. For the collected data, using the SPSS 18.0, the following analyses were implemented: frequency analysis, factor analysis, K-means clustering analysis, t-test, and ${\chi}^2$-test. Result. In terms of lifestyle, seniors had shown more active groups than passive groups in comparison to their juniors. The active group in terms of lifestyle has shown higher interest in the importance of apparel and fashion leadership in comparison to the passive group. The active group in terms of lifestyle has also shown higher interest in color in comparison to the passive group. Conclusion. A fashion leader leading by examining the fashion life style and color interest in accordance with the lifestyle to target college students to investigate a variety of consumption patterns made according to personal preference consists of a smooth communication between businesses and consumers needed for product development.

Purpose. The purpose of this study was to determine the using state of computers and internet in university students. Method. This research conducts a survey of 50 university students. Researcher personally visited lecture room to explain the purpose of research. The questionnaire was made by the researcher and consists of seven questions. Result. In this study, university students of 74% using computer more than one hour per day. The most of purpose of internet use was internet surfing and writing a document. University students of 42% were play games with internet. Conclusion. The continuous tracking is need of computer and internet use and need to be healthy for the use of guidance of university students.

Purpose. This study was to identify the relationship between self-directed learning and nursing student's satisfaction of clinical practice. Methods. This study was designed to measure the level of satisfaction according to the contents, guidance, environment, time, and the evaluation of clinical practice. Two hundred thirty-one nursing student from baccalaureate program in H-gun was sampled. A scale consisting of 75 questions, developed by the researcher, was used to gather data from September 14 through 27, 2012. The data was analyzed by descriptive statistics, paired t-test, pearson correlation, and multiple linear regression using the SPSS WIN 18.0 program. Results. The results were summarized : Self-directed learning didn't show a significant different by grade(t=0.83, p=.934). Nursing student's satisfaction of clinical practice didn't show a significant different by grade(t=0.26, p=.798). The relationship between self-directed learning correlated with the degree of nursing student's satisfaction in clinical practice(r=.44, p<.001). The factors of self-directed learning described nursing student's satisfaction of clinical practice as $R^2$=.215(F=9.858, p<.001). Conclusions. It was found that a higher degree of satisfaction in clinical practice depends on a higher degree of self-directed learning. Therefore, nursing faculty should plan intervention to improve satisfaction level of clinical practice by fostering self-directed learning.

Purpose. For more effective hospital management, it analyzes the trend through general characteristics, balance sheet, income statement, and financial ratio analysis, grasps the causes of the problems, and analyzes management of the hospital in order to use the result as baseline data for development of the hospital in the future. Methods. The collected data of 3 years from 2011 to 2013 about 3 tertiary hospitals in metropolitan cities from Alio (provider of public institution information; www.alio.go.kr), Health Insurance Review & Assessment Service (www.hira.or.kr), and the website of the Ministry of Health and Welfare (www.mw.go.kr) were analyzed and general characteristics, balance sheet, income statement, and financial ratio, analysis are used as data. Results & Conclusions. From the result of data analysis from 2011 to 2013, general characteristics, balance sheet, income statement, financial ratio analysis, and pie charts could lead to conclusions as follows. In the result of comprehensive analysis, the 3 tertiary hospitals showed increase of fixed expense due to extension of the buildings and so did the scale of fund and asset. Although medical revenue increased, the margin of increase for medical expense was greater than that of medical revenue, which consequently led to loss. In prediction for the 3 tertiary hospitals based on characteristics so far, it is expected to see improved revenue structure after building extension is completed, but it is necessary to exert management effort to maintain its optimal level by enhancement in stability of management and inventory turnover through management of inventories.

Purpose. The purpose of this study was to investigate knowledge, stress and nursing performance about care for delirium in geriatric hospital nurses. Methods. For this study, data were collected from 242 nurses employed at geriatric hospitals with the capacity of more than 100 beds which were located in A, P and Y cites. Frequency analysis, t-test and one-way ANOVA were utilized to analyze the data and Scheffe test was used to conduct post-hoc tests. Results. Nurses showed significant differences in the level of Knowledge, as well as terminal care performance by marital status, nursing experience. A significant relationship was found between knowledge, stress and Delirium care performance. Conclusion. This study found nurses perform delirium care with a high level of stress but with insuffiecient understanding, and thus, showed great needs for related training. Such findings can be useful to develop educational programs to improve knowledge on delirium and plans to reduce stress from delirium for geriatric hospital nurses.
