  • 본 연구의 목적은 간호사들의 공감수준을 측정하고, 공감수준이 그들의 삶의 만족도와 직무만족도에 미치는 영향을 알아보는 것이다. 공감수준, 삶의 만족도 그리고 직무만족도의 세 가지 요인들로 구성된 설문지를 부산지역 소재 병원에서 근무하는 간호사 150명에게 실시하였다. 간호사는 근무형태에 따라 교대근무 간호사와 비교대근무 간호사로 구분하여, 총 150개 중 144개의 설문지를 사용하여 IBM SPSS Statistics 21로 분석하였다. 교대근무 간호사는 공감수준이 높을수록 직무만족도가 높았고, 비교대근무 간호사는 공감수준이 높을수록 삶의 만족도가 높았다. 흥미롭게도, 공감수준은 교대근무 간호사의 직무만족도에 긍정적인 영향을 미쳤고(${\beta}=.282$, p=.006), 비교대근무 간호사에게는 삶의 만족도에 긍정적인 영향을 미쳤다(${\beta}=.252$, p=.048). 본 연구 결과, 간호사의 공감수준은 간호사의 삶의 만족도와 직무 만족도에 긍정적으로 영향을 주었다. 간호사의 공감 부족은 환자와의 갈등을 일으킨다는 사실에서 보듯이, 간호사의 직무수행을 향상시키기 위해서는 간호사의 삶의 만족도와 직무만족도에 있어 공감의 중요한 역할을 이해하려는 새로운 관점이 필요하다.

  • Objectives The purpose of this study was to compare the effects between the degree of herniated intervertebral lumbar disc (HIVD) at L4-5 level and improvement of low back pain treated by Korean Medicine therapy. Methods 567 patients who received inpatient treatment from May 2014 to December 2015 in the Daejeon-Jaseng of Korean Medicine Hospital were divided into 6 groups by the degree of HIVD at L4-5 level confirmed with a Lumbar spine magnetic resonance imaging. All patients received a combination of treatment including acupunture, chuna manual therapy, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, Normal stage on Intervertebral Lumbar Disc at L4-5 level group's Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) improvement was $1.30{\pm}1.62$, $4.52{\pm}11.82$ and $0.04{\pm}0.11$ respectively. Bulging group's improvement was $3.25{\pm}2.81$, $8.28{\pm}13.02$ and $0.09{\pm}0.17$ respectively. Spinal canal occupying ratio (SOR) less than 20 group's improvement was $2.15{\pm}1.92$, $11.79{\pm}17.81$ and $0.13{\pm}0.23$ respectively. SOR 20 to less than 40 stage group's improvement was $2.13{\pm}1.92$. $10.79{\pm}15.93$ and $0.10{\pm}0.26$ respectively. SOR 40 to less than 60 group's improvement was $2.16{\pm}2.24$, $9.80{\pm}16.62$ and $0.15{\pm}0.25$ respectively. Surgery group's improvement was $2.47{\pm}2.21$, $11.64{\pm}18.53$ and $0.15{\pm}0.27$ respectively (p<0.03). But there was no statistically significance between 6 group's improvement after treatment (p>0.05). Conclusions After inpatient treatment by Korean Medicine therapy, Most patient's pain, disability and Health Related Quality of Life was improved significantly. But there was no statistically correlation between the degree of HIVD at L4-5 level and improvement of low back pain. So We think that future research of higher quality and correct statistics shall be necessary.

  • The purpose of this study is to determine paternal rearing behavior according to rearing characteristics and demographic characteristics. This study is designed as descriptive survey. This study's subjects are 200 people who live in Daegu, Gyeongbuk, Seoul and Gyeonggido and they have preschool children of 3-6years old. They live with their children together and they are bringing up their children with a spouse, and they agreed with this study. It was measured by the instrument that 3 nursing scholars modified for content validity based on 18 items which developed parental behavior questionnaire of Bigner(l977). The data were analyzed by the SPSS/PC program with descriptive statistics, t-test and ANOVA test. It was used Scheffe' test as post-hoc measurement. As a result of analysis is the following. 1. The results that are measured paternal rearing behavior by mean and standard deviation are that 'activity of play interaction' score was the highest($280{\pm}.59$), and then 'activity of daily living'($2.41{\pm}.58$), and then 'activity of discipline'($2.40{\pm}.93$). The lowest area was 'activity of outhouse'($225{\pm}.85$). As examined paternal rearing behaviors by item, 'express physical affection to children' was the highest and the next items is 'consult with wife about children's rearing problem.'. Item that was shown the lowest score was 'wash children's dress'. 2. Compared paternal rearing behaviors level by demographic characteristics, that showed Significant differences among the fathers job type(F=3.492, p=.005), family monthly income (p=2.011, p=.047), children's number(F=4.641, p=.011). 3. Compared paternal rearing behaviors level by rearing characteristics, that showed significant difference in the satisfaction of marred life (F=3.932, p=.021). In spite of Paternal rearing behavior can influence on children's health and health activity, that is apt to exclude in various family health educational program development and application in nursing field. Therefore, nursing researches about paternal rearing behavior will have to be needed to study in the future.

  • All human health behavior is deeply rooted one's beliefs or value system usually encompassed within the culture in which they live. The Taegyo, based on Oriental folk medicine, is defined as the behavior and self care of pregnant women administered for herself and her fetus(unborn child). Taegyo is believed to be desirable, effective, and healthy behavior by most of Korean pregnant women. It is essential in our contemporary culture, to ascertain what the components of Taegyo are and to integrate them into current, western nursing care, particularly in the area of prenatal care. 910 Korean women were the subjects of this study, who were in a gestation period of pregnancy between 10 weeks to three months postpartum. The subjects were selected by clustered smpling from 10 representative cities in Korea. Data was collected from February 10 to March 30 1995 by a constructed Questionnaire which consisted of 95 items. The questionnaire was developed through three steps such as content analysis, calculation of content validity index, and pretest. Data was analyzed by descriptive statistics and rotated matrix factor analysis with pc-SAS. The mean age of the subjects was 28.9 years : 36.5% of them were employed and the mean income per month was about 2000 dollars. The component of Taegyo was clustered into five factors such as fetus psychological stability(equity), fetus personality development, maternal-fetal interaction, fetus intellectual development and physical health promotion. The variance of each factor were 23.7%, 8.3%, 4. 7%, 4.1%, and 3.3% respectively in that order. The Eigen value of each factor was 13.03, 4.57, 2.60, 2.23, and l.83 respectively. It was found that the Taegyo is an unique and holistic self care behavior of Korean pregnant women. Therefore it has been concluded that this study has broadened the understandability of the implications the Taegyo. It is suggested that further studies on the effects of the Taegyo are needed to provide a scientific basis for professional maternity nursing.

  • Background: Antibiotic resistance has been becoming serious challenge to human beings. Overuse of antibiotics, especially, for infants is concerned, but studies are very few for the prescribing pattern of antibiotic use for infants. This study analyzes prescribing patterns of antibiotics in outpatients of preschool children with acute respiratory tract infections in South Korea. Methods: Data are used from 2011 Health Insurance Review & Assessment Services-pediatric patients sample. Inclusion criteria is outpatient children (0 to 5 years) with top five frequent diseases. Prescription rates are analyzed by types of disease, provider, specialty, region, and ages. Binary or multinomial logit models are used to analyze determinants of providers' prescription pattern. Results: The main findings are as follows. First, distributions of prescription rates are shown as L-shape or M-shape depending on the types of disease. Second, the prescription variation is so large among providers, where providers are polarized as a group with low prescription rates and the other group with high prescription rates, though the shapes are shown diversified across types of disease. Third, prescription rates appear to be lower in pediatrics and higher in ENT (ear-nose-throat). Fourth, broad spectrum antibiotics are widely used among children. Finally, the logit analysis shows similar results with descriptive statistics, but partly different results across types of disease. Conclusion: Antibiotics for respiratory tract infections of infants are used excessively with a large variation among providers, and especially broad spectrum antibiotics are used. The prescription guideline for antibiotics should be provided for each specific disease to reduce antibiotic resistance in the future.

  • The aim of this paper is to discuss the effect of missing values in detecting differentially expressed genes in a cDNA microarray experiment in the context of a one sample problem. We conducted a cDNA micro array experiment to detect differentially expressed genes for the metastasis of colorectal cancer based on twenty patients who underwent liver resection due to liver metastasis from colorectal cancer. Total RNAs from metastatic liver tumor and adjacent normal liver tissue from a single patient were labeled with cy5 and cy3, respectively, and competitively hybridized to a cDNA microarray with 7775 human genes. We used $M=log_2(R/G)$ for the signal evaluation, where Rand G denoted the fluorescent intensities of Cy5 and Cy3 dyes, respectively. The statistical problem comprises a one sample test of testing E(M)=0 for each gene and involves multiple tests. The twenty cDNA microarray data would comprise a matrix of dimension 7775 by 20, if there were no missing values. However, missing values occur for various reasons. For each gene, the no missing proportion (NMP) was defined to be the proportion of non-missing values out of twenty. In detecting differentially expressed (DE) genes, we used the genes whose NMP is greater than or equal to 0.4 and then sequentially increased NMP by 0.1 for investigating its effect on the detection of DE genes. For each fixed NMP, we imputed the missing values with K-nearest neighbor method (K=10) and applied the nonparametric t-test of Dudoit et al. (2002), SAM by Tusher et al. (2001) and empirical Bayes procedure by $L\ddot{o}nnstedt$ and Speed (2002) to find out the effect of missing values in the final outcome. These three procedures yielded substantially agreeable result in detecting DE genes. Of these three procedures we used SAM for exploring the acceptable NMP level. The result showed that the optimum no missing proportion (NMP) found in this data set turned out to be 80%. It is more desirable to find the optimum level of NMP for each data set by applying the method described in this note, when the plot of (NMP, Number of overlapping genes) shows a turning point.
