This study was to identify the effects of using Gratitude Diary Writing on self-esteem and internal-external locus of control to adolescent. A randomized controlled experimental design was used. There were 20 participants in the experimental group, and 19 in the control group. Data were analyzed using Chi-square test, Fisher's exact test, t-test. The results of self-esteem(t=5.142, p=<.001) and internal-external locus of control(t=5.821 p=<.001)l showed statistically significant differences between the two groups. Using thank journal writing is effective in improving adolescents self-esteem and internal-external locus of control. If the gratitude diary writing effect of gratitude is verified by selecting a wide sample, it is expected that it will be helpful for generalize activities.

If a restriction is imposed only to a (proper) subset of parameters of interest, we call it a local restriction. Statistical inference under a local restriction in multinomial setting is studied. The maximum likelihood estimation under a local restriction and likelihood ratio tests for and against a local restriction are discussed. A real data is analyzed for illustrative purpose.

A phase III clinical trial of a new drug for neutropenia induced by chemotherapy is presented and consider adding random effects in crossover design which was used in the clinical study. The diagnostics for its heteroscedasticity based on score statistic is derived for detecting homoscedasticity of errors in crossover design. A small simulation study is peformed to investigate the finite sample behaviour of the test statistic which is known to have an asymptotic chi-square distribution under the null hypothesis.

In this paper we introduced a new score generating function for the rank dispersion function in a general linear model. Based on the new score function, we derived the null asymptotic theory of the rank-based hypothesis testing in a linear model. In essence we showed that several rank test statistics, which are primarily focused on our new score generating function and new dispersion function, are mainly distribution free and asymptotically converges to a chi-square distribution.

To increase reliability and performance of an IMS(Intelligent Manufacturing System), fault tolerant control based on an accurate fault diagnosis is needed. In this paper, robot FDI(fault detection and identification) is proposed for IMS where the robot is controlled with state estimates of a nonlinear filter using a mathematical robot model. The Chi-square test and GLR(General likelihood ratio) test are applied for fault detection and fault size is estimated by a proposed bias filter. Performance of the proposed algorithm is tested by simulation for studies.

The purpose of this study was to examine the part-time work experience of nursing students and its effects on their interpersonal communication competence, self-efficacy and social skills. The study subjects were 362 nursing students in areas S, B, G and G. The relationship between the nursing students' part time work. experience and their general characteristics was analyzed by the Chi-square (${\chi}^2$) test and Fisher's exact test. The interpersonal communication competence originating from the general characteristics, self-efficacy, and difference in the social skills standard among groups were analyzed by the t-test, and analysis of variance (ANOVA). Among the 326 participants, 91.7% had part-time experience and 8.3% had no part-time experience. There was a significant relation between the part-time experience and economic level. Those having a low economic level were more likely to have part time work experience. The interpersonal communication and social skills of the students who had part time work experience when they were middle school students were lower than those who had such experience after high school. Further research is needed to identify precisely the advantages afforded by the part-time work experience of the nursing students.

This study was performed to examine the effect of convergence-based simulation education on the problem solving ability and self-efficacy and confidence of core fundamental nursing skill performance for nursing students. A non equivalent control group post-test only design was utilized(experimental group(n=97), control group (n=87)). Data were analyzed using independent t-test, Chi-square test and Pearson's correlation. The scores of the problem solving ability(t=-2.04, p=.043) and confidence of core fundamental nursing skill performance(t=5.31, p<.001) were higher than those of the experimental group than control group. It is necessary to find ways to iterative and convergent research that verifies the continuous development and effectiveness of various courses.

The purpose of this study was to investigate the effect of small group collaboration learning program through MBTI on interpersonal relationship and career identity of nursing college students. 30 experimental group and 30 control group, nursing students were randomly assigned 2nd grade nursing students were selected from nursing program of T university in Daegu, Korea. The 30 experimental group students received small group collaboration learning program through MBTI for 30 hours(2 times in a week for 15 weeks). Measures were MBTI test, interpersonal relationships and career identity scale. The data were analyzed with SPSS Win 17.0 program, chi-square test, t-test. The experimental group which received small group collaboration learning program through MBTI will have a higher level of interpersonal relationships and career identity change score than the control group.

This study was conducted to develop and test the effects of an emotional intelligence program for new nurses. The study design was a mixed method research. Participants were 29(intervention group: 15, control group: 14) new nurse. The emotional intelligence improvement program was conducted once a week for a total of 8 weeks (20 hours).The emotional intelligence program was provided for 8 weeks (20 hours). Quantitative data were analyzed using Chi-square, Fisher's exact test, t-test, repeated measure ANOVA with SPSS/WIN 18.0. Qualitative data were analyzed using content analysis. Quantitative results showed that emotional intelligence, Job stress were no significantly better in the experimental group compared to the control group. According to the qualitative results, the new nurse experienced improvement in emotional intelligence, empowerment, a reduction in stress, Changed from 'alone' to 'us', and as well as I dream of my future self after participation in the emotional intelligence program. A study to apply the emotional intelligence improvement program to nurses at various times and to verify its effectivene.

The paper describes on the hydrologic analysis of point rainfall data of the three major areas, such as in Seoul, Pusan and Taegu. Scheme of the paper is analyzed five research cases. Contents of the analysis are carried out five kinds of transformed variables for determination of rainfall distribution types and two kinds of reliability tests on unusual(extraordinary) values each rainfall durations:short durations, long durations, long durations, monthly and yearly. Rainfall depth probability had been computed methods of hydrologic amounts analysis namely logarithmic transformations or Gumbel-Chow method and so on, but in this paper it is calculated log xi, n-square root transformations by using normal distribution function and normalization of rainfall distributions is examined graphical tests and $X^2-test$(chi-square test). Furthermore, rainfall depth probability is calculated taking into account the safty factors of project life of hydraulic structures. We think it is advanced contents that considering priceless experiences, the life of structures, conditions and more problems of planning engineers and designers, proposed rainfall amounts(proposed values) are presented charts or figures.
