The purpose of this study was to investigate the nursing behavior and delegation status of nursing hospital nurses and to provide basic data for improving the quality of medical services. The subjects of this study were data collected from July 26 to December 23, 2013, for 140 nurses with more than 3 years of experience in nursing hospitals. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and One way ANOVA of SPSS 20.0 statistical program. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and one way ANOVA of SPSS 20.0 statistical program.. As a result of this study, the case of delegation of nursing behavior was higher in case of no protocol of nursing delegation procedure than in case of having protocol. This study suggests that nursing practice of nursing hospital nurses can be a major factor in declining the quality of medical services in the absence of specified standards or procedures for delegation. Procedures, methods and guidelines are required.

In this study we focus on variable selection in decision tree growing structure. Some of the splitting rules and variable selection algorithms are discussed. We propose a competitive variable selection method based on Kruskal-Wallis test, which is a nonparametric version of ANOVA F-test. Through a Monte Carlo study we note that CART has serious bias in variable selection towards categorical variables having many values, and also QUEST using F-test is not so powerful to select informative variables under heavy tailed distributions.

This study explored the instrumental values of homemakers by object family living and other social living. Homemakers' instrumental values on family living were compared with those on other social living. Through this it make to explain differences in instrumental values on 2 objects. 650 homemakers were adapted as data. The data were analyzed by frequency percentage means one-way ANOVA duncan-test and paired T-test The results showed significant differences in instrumental values by objects.

Purpose: This study was done to examine the effects of 4% hypertonic saline solution mouthwash and tooth brushing education on the oral health of elders living in long term care facilities. Methods: In this quasi-experimental study, the participants were assigned to a 2% experimental group (n=20), a 4% experimental group (n=20), and a control group (n=20). Data were analyzed using ANOVA, repeated measures ANOVA, Fisher exact test, Chi-square test, Kruskal-Wallis test and multiple response analysis with the SAS program. Results: Regular tooth brushing and use of 4% hypertonic saline solution mouthwash by elders provided better oral health by decreasing xerostomia, oral tongue plaque, halitosis, and the number of oral bacteria. Conclusion: The results indicate that regular tooth brushing with continuous 4% hypertonic saline solution mouth washing education promotes oral health for elders in long term care facilities, thus the dental care described in this study is recommended for elders in long term facilities.

This study makes a relative comparison of the results of tensile test and quasi-static analysis using AGL(Adjuster Guide Loop) model that plays a role in adjusting the height of shoulder belt, of the components of the vehicle seatbelt system and attempts to propose a method of reducing the error rate of the quasi-static analysis technique effectively. This study selects two major factors affecting the result of an analysis, draws the result of analysis through the method of experimental design, one of the statistical techniques and understands the contribution rate of the major factors affecting the result of the analysis through ANOVA(Analysis of Variance).

The paper examined and analyzed the factors affecting TQM in Medical libraries. The questionnaire was used for collecting data and the ANOVA and T-TEST were used for analyzing data. The results showed that librarians positively recognize the need of TQM in Medical libraries. However, the results showed that library system needs to improve the reward system for effective performance of the work. Finally, this study showed that librarians need to be well-qualified person as a professional with the CEO of strong leadership for successful TQM.

The Study was conducted to understand the degree of knowledge, awareness and performance of nursing students' patients' personal information protection and to grasp the relationship between them. A convenience sample 262 nursing students was selected from C do, between 1 November and 8 November 2019. Using SPSS Program t-test, one-way ANOVA, Pearson's correlation analysis were performed. Factors that influenced knowledge, awareness and performance included grade, education of information. It is necessary to develop and test programs to ensure an improvement in knowledge and awareness among nursing students to increase their performance.

The purpose of this study was to analyze the influencing relationships among the preparation for the old age, social networks, and the enterpreneurial intention of the potential enterpreneurs. 305 numbers of structured questionnaires were collected from the potential enterpreneurs and analyzed through SPSS WIN 21.0 using frequency, validity test, t-test, ANOVA, and regression analysis. The result are as follows. Firstly, the effects of the emotional and economical preparation for the old age on the entrepreneural intention of the potential enterpreneurs were shown as negative. Secondly, the social networks affects the enterpreneural intention of the potential enterpreneurs negatively.

Even though two different preparations are chemically equivalent, the variance of bioavailability differenciates the clinical effect of preparations, so that the preparations need to be evaluated by comparing bioavailability in vivo as well as chemical equivalence. In this study, bioequivalence tests of commercially available isoniazid tablets A, B, C and D (standard) were performed to give some guidelines to bioequivalence test. The bioavailability parameters obtained by drug administeration were statistically analyzed. Statistical evaluation of the data involved an analysis of variance for a cross over design. Cross over design was employed with 8 healthy volunteers. The results were within 20% difference of mean value in the AUC, Cmax, Tmax and amount of urinary excretion (Au) between standard and isoniazid tablets. The results of ANOVA showed no significant differences for 'group or sequence', but almost not for 'between subjects'. The tablet. A, B and D were within 20 min, but tablet C was within 50 min. Tablet A was biologically equivalent in the Au. tablet B biologically equivalent in the Au and AUC. Tablet C was biologically equivalent in the Au. The relationship between the dissolution rate and Au was significant.

In this paper, a multiple comparison was proposed to minimize the amount of coolant. And new coolant level, called "low level", was suggested to show usefulness of multiple comparison for experiments. The amount of this levee is about 1/4 of conventional coolant amount-called "high level", and dry cutting is called "none level". Using these coolant levels, the cutting temperatures of each coolant level in turning process were analyzed by analysis of variance(ANOYA)-test and a multiple comparison. As the result of ANOVA-test, we have just known that the average of temperature of each coolant level is not equal. However by Tukey's HSD, one of multiple comparison. it was analyzed that the average of temperature of low level is similar to that of high levee and different from that of none level.erent from that of none level.
