The purpose of this study was to identify the variables affecting parenting efficacy of North Korean refugee mothers. The selected variables were marital satisfaction, social support, and acculturation. The participants consisted of 105 mothers who had defected from North Korea with preschool children living in Seoul, Gwangmyeong-si, and Gyeongsangnam-do provinces. The data thus collected were analyzed by descriptive statistics, t-tests, correlation, and multiple regression analysis. The results indicated that the marital satisfaction and social support had meaningfully positive effects on the parenting efficacy of North Korean refugee mothers. However, marginalization was found to be a predictor of competence-anxiety in parenting. The selected variables derived from the environmental systems in maternal parenting were significant factors in the parenting efficacy of North Korean refugee mothers and furthermore, their sociocultural environments were also important in parenting. These findings clearly showed that marital satisfaction and social support were the most significant variables of parenting efficacy of North Korean refugee mothers. The results of this study appear to have a great deal of utility as preliminary data to improve the parenting efficacy of North Korean refugee mothers.

Purpose: We investigated the relationship between the muscle activity and kinematic variables of the upper extremity during a push-up task on stable and unstable surfaces. Methods: We recruited 15 healthy subjects. Subjects completed the push-up task on stable and unstable surfaces. Surface electromyograms were recorded from the serratus anterior, upper trapezius, latissimus dorsi, infraspinatus to monitor changes in muscle activity. Markers for kinematic changes of elbow flexion, shoulder extension, shoulder retraction and scapular adduction were attached at C7, the T7 spinous process, both acromions, the scapula superior and inferior angle, the humerus lateral epicondyle, and the ulnar styloid process. Correlation coefficients between muscle activity and kinematic variables were analyzed by SPSS for Windows, version 15.0. Results: On the unstable surface, elbow flexion and shoulder extension increased with increasing muscle activity of serratus anterior, upper trapezius and infraspinatus. On the stable surface, shoulder retraction decreased with increasing muscle activity of serratus anterior and infraspinatus. Scapular adduction decreased with all types of increasing muscle activity, regardless of the support surface. Conclusion: Correlations between muscle activity and kinematic variables were observed on stable and unstable surfaces during a push-up task, while correlations between right and left variables were not clear. These finding suggest that it may be used to develop a rehabilitation program which could be effective in improving shoulder function in patients with shoulder problems.

본 연구는 간호대학생이 임상실습 중 태움관찰경험과 간호전문직관 정도를 파악하고, 간호대학생의 전공몰입에 미치는 영향을 알아보기 위해 시도되었다. 연구대상자는 두 개의 대학교에 재학 중인 간호대학생 195명이었고, 구조화된 설문지를 통해 수집된 자료는 t-test, ANOVA, Pearson's correlation 및 다중회귀를 사용하여 분석하였다. 연구결과 간호대학생의 전공몰입에 영향을 미치는 요인에 대한 회귀모형은 유의한 것으로 나타났고(F=11.60, p=.000), 태움관찰경험(ß=-.13, t=-1.99, p=.048), 간호전문직관(ß=.20, t=2.99, p=.003)과 학교만족도(ß=.31, t=4.58, p=.000)가 영향 요인으로 나타났으며, 이들 변수들의 설명력은 27.1%이었다. 본 연구를 통해 미래의 간호사인 간호대학생들이 향후 태움의 가해자와 피해자가 되지 않도록 적절한 전문직관과 전문직 태도를 형성할 수 있는 교육 프로그램을 개발할 필요가 있음을 확인하였다.

This paper presents an experiment study on the control of a rotary-type inverted pendulum based on the Takagi-Sugeno (T-S) fuzzy model approach. A sufficient condition for stability of the T-S fuzzy control system is given via linear matrix inequalities (LMIs). State-feedback controllers for sub-systems are designed from the sufficient condition via change of variables which is one of the popular LMI techniques. Experimental results on a rotary-type inverted pendulum control show the feasibility of the T-S fuzzy model-based control method.

Let {$X_{ni}$ | $1{\leq}i{\leq}n,\;n{\geq}1$} be an array of rowwise negatively dependent (ND) random variables. We in this paper discuss the conditions of ${\sum}^n_{t=1}a_{ni}X_{ni}{\rightarrow}0$ completely as $n{\rightarrow}{\infty}$ under not necessarily identically distributed setting and the strong law of large numbers for weighted sums of arrays of rowwise negatively dependent random variables is also considered.

The purpose of this study is to examine consumer characteristics according to the recycling behavior and analyze the affected variables on recycling behavior. For the empirical analysis, the data was collected 585 consumers from May 14 to June 8,2001. The statistical methods for this study were descriptive statistics, t-tests, cross tables, ANOVA and multiple regression analysis using SPSS PC program. The major findings of this study were as follows: 1. Convenience was important variables to explain the recycling behavior of household trash between two groups, but extrinsic incentives of rewards for undertaking the behavior was not significant. 2. Intrinsic motivation like as perceived consumer difficulties(PCD), perceived consumer effectiveness(PCE), recycling altitude, and ethic was significant variables to compare two groups. 3. Recycling knowledge was important to explain the recycling behavior, but no impact on recycling behavior. 4. Except age, all of socially demographic variables were significant to compare the recycling behavior of two groups. 5. Recycling attitude and convenience had influence on recycling behavior. Especially, ethic had influence on low level recycling behavior of consumer group.
