Since patients who have suffered from strokes have chronic health problems, the development of a protocol for home care nursing is required. Therefore, this study was done to test the effects of such a protocol on stroke patients. This study was conducted by using a single group pre-post design. The subjects for the study were 13 home care nurses and 30 home care patients who had a stroke. Data collection was done from October 1997 to February 1998. The collected data was analyzed using the Wilcoxon signed rank test and paired t-test and the results were as follows : 1. The first hypothesis that 'working satisfaction of home nurses would be higher after using the home care protocol' was supported. 2. The second hypothesis that 'patients' satisfaction would be higher after using the home care protocol' was rejected. 3. The third hypothesis that 'the level of ADL of patients would be higher after using the home care protocol' was supported. In conclusion, by using a home care protocol, the satisfaction of nurses' work and the ADL of patients increased, and the patients' satisfaction also increased without statistical significance. The above results confirm that the application of a home care protocol is very effective. Thus, this protocol can be helpful in the quality care of stroke patients. Therefore, developing and organizing protocols, according to health problem, can be useful for beginner nurses who interact with high risk patients.

The cutaneous stimulation is an independent nursing intervention used in various painful conditions, and is explained by gate control theory. This study was aimed at identifying the effect of cutaneous stimulation on reduction of arteriovenous fistula puncture pain of hemodialysis patients. One group repeated measurement post test research was designed. Forty-five hemodialysis patients who received arteriovenous fistula puncture regulary in hemodialysis units of an attacted D hospital to K university have been studied from August 16 to 21, 1993. First the arteriovenous fistula puncture pain of control period was measured, and then the arteriovenous fistula puncture pain of experimental period(with cutaneous stimulation) was measured. The instrument used for this study were visual analogue pain scale as subjective pain measurement, objective pain behavior checklist and Spielberger's Trait Anxiety Inventory as intervening variables. Analysis of data was done by use of paired t-test, t-test, ANOVA and Perarson correlation coefficient. The results of this study were summarized as follows; 1) The first hypothesis that the subjective pain score of arteriovenous fistula puncture pain in experimental period(with cutaneous stimulation) will be lower than in control period was partly supported. The subjective pain score of arterial line was rejected(paired t=-0.28, p=0.77) and the subjective pain score of venous line was supported(paired t=2.61, p=0.01). 2) The second hypothesis that the objective pain behavior score of arteriovenous fistula pain in experimental period(with cutaneous stimulation) will be lower than in control period was rejected(arterial line paired t=-0.45, p=0.65; venous line paired t=-0.36, p=0.72). 3) The third hypothesis that the cardiopulmonary signs of arteriovenous fistula puncture pain in experimental period(with cutaneous stimulation) will be lower than in control period was rejected(pulse paired t=-0.8, p=0.42; systolic BP paired t=0.98, p=0.33; diastolic BP paired t=0.43, p=0.66). Further experimental studies with simple intravenous injection patients will be recommended in order to identify the effect of cutaneous stimulation.

This paper presents practical issues for test and evaluation(T&E) methods to develop defense systems. Our argument is motivated by several domestic defense cases and the cases lead us to discuss two main factors for reliable defense systems development: 1) statistical approaches and 2) technical schemes. Specifically, statistical approaches enable to provide credible interpretations about T&E results in the decision-making process. With practical T&E results of the “Red Shark” torpedo, we performed statistical hypothesis tests and suggest a minimum sample size to accept the hypothesis. Next, technical schemes have more direct effects on improving reliability of developed defense systems and we shortly introduce tools development for systems verification that is required to integrate several sub-systems, e.g., combat, sensor, weapon, and communication systems, within a defense system. We additionally summary some domain cases using modeling and simulation techniques for successful T&E. In closing, we expect that the paper shows empirical investigation and lessons learned with these two practical issues, which provides a guide those who desire to make decisions about reliable defense systems development.

Random walk is used for describing random phenomenon in various areas but tests for random walk developed so far are known to suffer from size distortion and low power. Kim et al. (2014) proposed a sign test for unit root (${\rho}=1$) hypothesis based on slopes. This article proposes a Wilcoxon signed rank test based on slopes for unit root hypothesis, and compares it with the augmented Dickey-Fuller test and the sign test by a simulation study. Our results confirm that the nonparametric tests are better than ADF test for small samples like n = 30. The results also show that the sign test is better than the Wilcoxon signed rank test and that for 0 < ${\rho}$ < 1 (-1 < ${\rho}$ < 0), the nonparametric tests suffer from power loss (improvement) as normal error changes to double exponential error.

The relationships between children's health behavior and variables that effect children's health behavior has been investigated in a number of previous studies. This study was conducted to examine the effects of a peer's social reinforcement on children's dental health behavior in an elementary school. The research design was a nonequivalent pre and post-test quasi-experimental design and the study subjects with one hundred and thirteen eight to nine years old children, and their mothers (57 experimental group, 56 control group) were selected as a study group. Subjects were selected by the convenience sampling method. The study was carried out in an elementary school in Namwon city, Korea, from the 26th of April to the 12th of June in 1999. Data were collected in both the pre and post-test portions. Using the "Health Belief Model", each item of the questionnaire for measurement of dental health behavior was modified and administered for the children and their mothers. The questionnaire for the measurement of dental health behavior was developed by Oh, Y.B.(1994). The Cronbach's ${\alpha}$ of the questionnaire for children were .81, and for the mother were .79. In this study, the health belief model consists of "perceived susceptibility", "perceived seriousness", "perceived barrier", "perceived salience", and "perceived benefit". The questionnaire for the children was composed of 37 items, and the questionnaire for the mother was composed of 40 items. Data were analyzed by frequency, ${\chi}^2-test$, ANOVA, Pearson's Correlation, and multiple regression analysis by a SAS program. The results of this study were summarized as follows ; 1. The first hypothesis that the experimental group would have more change in the frequency of brushing per week than that of control group was accepted(t=3.817, p=0.000). Mean tooth brushing scores in the experimental group improved significantly from pre-test to post-test, but in the control group there was no significant improvement in tooth brushing scores. 2. The second hypothesis that the experimental group would have more change in score of dental health behavior than that of control group was accepted(benefit : t=2.804, p=0.006, salience: t=2.608, p=0,010). An evaluation between the experimental group and the control group showed significant change from pre-test to post-test in health behavior scores. 3. The third hypothesis that higher scores of social reinforcement would create more change in the scores of tooth brushing frequency in the experimental group was accepted(${\beta}$=0.169, p=0.000. Multiple regression was used to examine the peer's social reinforcement scores and the relative influence of significant variables in previous ANOVA and Pearson's correlation test on children's frequency of brushing during the post-test. The results of the study indicated that the combination of social reinforcement of peers with variables pertaining to mother and householder were significantly related and effectively improved a child's tooth brushing.

Purpose - The TOEIC test has been leading the change in the quality and the globalization of companies for about last 30 years. The TOEIC test is taken by about two million people each year and is used as a criterion to select new employees in companies or government offices, for performance ratings, and for overseas posting selections. Universities also use TOEIC test in various ways. Since the TOEIC test is used for the selection of new students for admission, transferring extra credits, scholarships, graduation certification, and admission of international students studying abroad, many universities all over the country provide students with TOEIC study lectures through their own language institutes. Despite the fact, there has been no research on the service quality or even the current situation of these institutes. Thus, this study aims to evaluate the factors that impact TOEIC lecture service quality and analyzes the effect of the expectation related to the education service quality and the result of education on intentional behavior. Research design, data, methodology - Data was collected by administering a survey to current TOEIC students from different university language institutes. The survey questionnaire comprised of a five-point Likert scale. The demographic analysis was conducted using the frequency analysis method and the factor analysis was conducted to verify the validity of questionnaire over any variable. The reliability analysis was conducted to verify the reliability of the results. Besides, multiple regression analysis, regression analysis, and mediated effect verification were also conducted. For education service quality, four different independent variables such as reliability, response, conviction, and sympathy were considered using the SERVQUAL survey model. Based on the research models, the study hypotheses below were formulated in order to recognize an effect relationship between the variables. The four hypotheses are, "the hypothesis on education service quality and TOEIC study result expectation," "the hypothesis on education service quality and behavioral intention," "the hypothesis on study result expectation and behavioral intention," and "the hypothesis on study result expectation and mediated effect." Results - The results are as follows. First, the factors like response, conviction, and sympathy have a positive influence on TOEIC study result expectations. Second, the TOEIC study result expectation has a positive influence on the factors of behavioral intention such as re-sign up, positive word-of-mouth, "loyalty towards school." Third, it was verified that the mediated effect on behavioral intention was influenced by education service quality at university foreign language institute, while the study result expectation has only a partial mediated effect. Conclusions - The implications of this study are summarized as follows: First, it suggests a new research model for the effect of the expectation related to the education service quality and the result of education in the university language institutes on the behavioral intention. Second, it has established a relationship between the education service quality and study result expectation by verifying the mediated effect on them.

Falls are one of the most serious problem that threatens the health of the elderly. This study was conducted twice a week for six weeks from May to June 2014 to evaluate the effectiveness of fall prevention exercises for rural seniors. This study analyzed the effects by comparing before and after exercise on the TUG, FRT, BBS, ADL, fear of falls, fall efficacy, and depression. The results of this study was as follows: Hypothesis1, "a TUG of post-test will improve more than the pre-test", was supported. Hypothesis3, "BBS of the post-test would improve more than the pre-test" was supported. In addition, the FRT, ADL, fear of fall, fall efficacy, and depression of post-test would improve more than the pre-test. Accordingly this study showed that fall prevention exercises are effective in improving the physical function (TUG, FRT, BBS, and ADL) and emotional function (fear of fall, fall efficacy, and depression) in rural seniors.

Purpose: This study was done to evaluate the Military Mental Health Promotion Program. The program was an email based cognitive behavioral intervention. Methods: The research design was a quasi-experimental study with a non-equivalent control group pretest-posttest design. Participants were 32 soldiers who agreed to participate in the program. Data were collected at three different times from January 2012 to March 2012; pre-test, post-test, and a one-month follow-up test. The data were statistically analyzed using SPSS 18.0. The effectiveness of the program was tested by repeated measures ANOVA. Results: The first hypothesis that the level of depression in the experimental group who participated in the program would decrease compared to the control group was not supported in that the difference in group-time interaction was not statistically significant (F=2.19, p=.121). The second and third hypothesis related to anxiety and self-esteem were supported in group-time interaction, respectively (F=7.41, p=.001, F=11.67, p<.001). Conclusion: Results indicate that the program is effective in improving soldiers' mental health status in areas of anxiety and self-esteem.
