  • The purpose of this study was to examine early emotionality and mothering and fathering antecedents of inhibition of children at age 3 years in a sample of 100 children(51 boys; 49 girls). In order to assess child's behavioral inhibition and mothering, the behaviors of each child-mother dyad was videotaped in a structured lab situation. Data on Fathering behavior were gathered through questionnaires. 2X2ANOVA, Hierachical Regression Analyses and Fisher's Z test were conducted for the statistical analyses. The main results were as follows; 1) Only small portion of the variance in subsequent inhibition could be explained by early emotionality(i.e.negative, positive, and the interaction of both emotionality). 2) High negativity coupled with low positivity in infancy predicted high inhibition especially for girls. 3) In general, sensitive mothering and appropriateness of mothers' response were related to child's low inhibition, while parental intrusiveness and negative affect increased child's inhibition. 4) Mothering appeared more influential in the case of children who showed low positivity during infancy. The importance of distinguishing positive and negative emotionality in infancy and studying parental behavior to predict child's inhibition were discussed.

  • Purpose: The purpose of this study was to examine the effectiveness of smartphone use to enhance self-efficacy and decrease loneliness in elders through communication using the SNS Program Methods: Participants in this study were assigned to the experimental group (25) or control group (25). Data were collected from June 3 to July 12, 2019. For this study, the communication Program through SNS was run once for a total of 12 sessions. All data were analyzed using SPSS version 18.0 program, 𝑥2 test, t-test, Repeated Measure ANOVA and Fisher's exact test. Results: It was found that H1 was supported (z=-4.12, p=.005) as "the experimental group participating in the communication Program through SNS had greater self-efficacy than the control group". H2 was supported as "the experimental group participating in the communication Program through SNS had less loneliness than the control group", (z=3.20, p<.001). Conclusion: This basic information may be used as an intervention on communication Program through SNS. Findings suggest the necessity of improving self-efficacy and reduction of loneliness through an intervention communication Program through SNS.

  • Purpose: To Perform a randomized comparative study investigating the effects of Pelvic Floor Muscle Exercise(PME) and Magnetic Stimulation Therapy(MST) and to identified the problems in each of PME & MST Method: Forty-nine patients with mild stress incontinence were randomly assigned to either of two treatment groups (24 patients in the PME group and 25 in the MST group). The PME group had a video exercising program for 40 times every day during 6 weeks. The MST group was treated with BioCon-2000TM, 2times/ week for six weeks. Pre-test and post-test were performed by Prineometer, 1-hour pad test. and Jackson's BFLUTS questionnaire of Jackson. Collected data were analysed using SAS 9.1 by frequency, Kolmogorov-Smirnov Z. Chi Square-test, t-test, Fisher Exact probability test, Paired t-test, and Wilcoxon's rank sum test. Results: In comparison between before and after PME and MST, statistically significant difference was observed in maximal vaginal pressure, duration of vaginal contraction, amount of urine, and symptom of urination. In the comparison of the effectiveness between PME & MST, only the maximal of vaginal pressure (Z=2.58, p= .010) was significantly different. Conclusion: The factor more effective in the MST group than in the PME group was high compliance.

  • Purpose: This study was done to examine effects of a discharge education program using on-line community on parenting stress, baby care confidence for mothers of premature infants and health problem of premature infants. Methods: Using a non-equivalent control group pretest-posttest quasi-experimental design, 32 participants were assigned to an experimental (17) or a control group (15). Mothers in the experimental group were introduced to the discharge education program 2 weeks before the baby was discharged. They participated in the on-line community for 4 weeks after discharge. Parenting Stress Index and Baby Care Confidence Scale were utilized for data collection. Data were analyzed using descriptive statistics, $X^2$-test, Fisher's exact test, and Mann-Whitney U test with the SPSS program 16.0 version. Results: In the experimental group, mean scores for parenting stress were lower than for the control group (Z=-3.176, p=.001), while scores for confidence in baby care were higher than for the control group (Z=-3.195, p=.001). Conclusion: Findings indicate that discharge education programs using on-line community have the positive effect of decreasing parenting stress and increasing baby care confidence for mothers and decreasing health problems for infants. Therefore utilization of the internet and online community to educate parents of premature infants is recommended.

  • Many empirical research surveys have su, pp.rted that Organizational Citizenship Behavior(OCB) is influenced by or closely related with leadership styles. The primary purpose is to test the moderating effects of structural factors (formalization, centralization) and personal factors(growth needs, sex, age, tenure, rank, occuption, school carrer) between 2 leadership styles and 2 OCB factors. For the analytical purpose of this article, Fisher's Z-transformation and SGC(split groups correlations) methods were introduced. Generally 2 leadership styles are found to influence on altruism and conscientiousness respectively. Out of 36 cases, only 2 cases were significant in moderating effects. Based on empirical results, there is no moderating effects in conscientiousness. But altruism is found to more closely related with employee-centered leadership in low centralized group than in high centralized group, and more closely related with job-centered leadership in low growth-needs group than in high growth-needs group.

  • This study examined the reliability and validity evidence of the Korean version of Wechsler Primary & Preschool Scale for Intelligence(K-WPPSI-IV), which was standardized recently. Following the stratified sampling for Korean population in terms of region and maternal education level, 1,700 children aged 2.6~7.7 years were recruited for Korean norm development. The split-half reliability (N=1,700) was high(Fisher's z(.75-.89)) and test-retest reliability(N=100) was satisfactory ranging from .95 to .68. The inter-rater reliability(N=110) was very high(.96-1.0). Discriminant and convergent validities were revealed by correlational patterns among subtests and indices. Future studies are needed to extend both reliability and validity of K-WPPSI-IV by collecting data with a various sample group and a variety of instruments.

  • Although the study of OCB has increased greatly in recent years, a little works have focused on the relationship between leadership and extrarole behavior, and the moderating effects of the situational factors on the relationship between two factors. For the analytical purpose of this article, Fisher's Z-transformation and SGC(split groups correlations) methods were introduced. Generally 2 leadership styles are found to have influenced on altruism and conscientiousness respectively. Out of 36 cases, only 2 cases were significant in moderating effects. Based on empirical results, there is no moderating effects in conscientiousness. But altruism is found to be more closely related with employee-centered leadership in low centralized group than in high centralized group, and more closely related with job-centered leadership in low growth-needs group than in high growth-needs group.

  • The EWMA(Exponentially Weighted Moving Average) has recently received a great deal of attention in the quality control literature as a process monitoring tool on the shop floor of manufacturing industires, since it is easy to plot, to interpret, and its control limits are easy to obtain. Most a, pp.ications of the EWMA for process monitoring have concentrated on the problem of detecting shifts of a process mean and a process standard deviation with ARL(Average Run Length) properties. But there may be the necessity of controlling linearity on product quality such as the correlation coefficient to the process operator. Control managers may want to protect the increase of a process correlation coefficient value, such as 0, between two variables of interest. However, there are few studies concerned on this part. Therefore, we propose EWMA models for a process correlation coefficient using two transformed statistics, T-statistic and (Fisher's) Z-statistic. We also present some results of simulation by SAS/IML and compare two models.
