본 연구의 목적은 비 체중지지 자세 상태에서 발목관절 발등굽힘 관절가동범위에 따라 동적 균형 능력을 평가하는 Y-Balance Test와의 관계를 규명하고자 하였다. 본 연구에는 10년 이상의 축구경력을 가진 K3리그에 정기적으로 참여하는 남자축구선수 27명이 참여하였다. 발목관절의 발등굽힘과 동적균형 능력과의 관계를 검증하기 위해 The Pearson Rank Correlation Coefficient를 사용하였다. 본 연구의 결과 HADR군에서 PLRD(P<.05)와 CS(P<.01)에서 유의한 차이가 나타났으며, 발목관절 발등굽힘의 관절가동범위와 PMRD, PLRD 및 CS에서만 중증도의 유의한 상관관계가 나타났다. 따라서 발목관절 발등굽힘의 감소는 균형 능력 감소와 관련이 있으며, 축구선수의 손상을 예방하기 위해서는 정기적인 발목관절 관절가동범위의 평가뿐만 아니라 무릎과 엉덩관절의 근력 및 고유수용감각을 향상시키기 위한 트레이닝이 필요할 것으로 생각된다.

본 연구는 간호대학생의 성지식, 성태도, 생식건강증진행위를 확인하고 이들의 상관관계 확인을 위한 서술적 조사연구이다. 간호대학생 300명을 대상으로 설문하고 229부로 분석하였다. 연구도구는 Jeon(2004)의 성지식, Ho(2009)의 성태도, Jo(2014)의 생식건강증진행위 측정도구를 사용하였다. 자료분석은 일반적 특성은 실수와 백분율, 평균과 표준편차, 성지식, 성태도, 생식건강증진행위는 평균과 표준편차를 이용하였다. 일반적 특성에 따른 성지식, 성태도, 건강증진행위 차이는 independent t-test, one-way ANOVA, 사후검정으로 Scheffe's test를 이용하였다. 상관관계는 Pearson's correlation coefficients로 분석하였다. 여학생의 성지식이 높았으며, 생식건강증진행위 교육은 저학년이 적절한 시기임을 알 수 있다. 또한, 성지식이 높을수록 생식건강증진행위가 높아 생식건강증진행위 향상을 위한 성교육의 필요성이 여전히 요구됨을 시사한다. 이에, 본 연구는 간호대학생의 생식건강을 위한 상담과 교육에 활용할 생식건강증진행위의 교육자료 개발에 기초자료로 활용될 수 있을 것이다.

This study tested the relations of schools organizational climate and teachers' job stresses, perceived by 913 teachers from 45 elementary, junior- and senior-high schools. Pearson's correlation analysis for the relations between the sub-factors of both organizational climate and job stresses and cannonical correlation analysis for the relative contribution of individual variable of organizational climate upon job stress were applied for the test. The results of Pearson's correlation analysis showed that while 'intimacy', 'esprit', 'considerations', and 'production emphasis' climate had negative correlations with job stress sub-factors, 'disengagement' and 'aloofness' climate had positive correlation. 'Student guidance', a sub-factor of job stresses, did not have statistically significant correlation with any sub-factors of organizational climate. Findings from cannonical correlation analysis showed 2 significant cannonical functions to explain the relations between the sets of variables. 'Disengagement' from organizational climate positively contributed with 'authority forfeiture' and 'dissention and conflict' of the job stresses variables.

Purpose. The objective of this study was to investigate factors influencing turnover intention index of work environment, emotional labor by hospital nurses Methods. A survey was conducted with 290 nurses who were working hospital. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with SPSS window 18.0 program. Result. Findings revealed that; 1) The mean scores were 2.81 [range : 1-5] for work environment, 3.24 [range : 1-5] for emotional labor, 3.43 [range : 1-5] for turnover intention. 2) Pearson's correlation revealed work environment was negatively correlated with turnover intention but emotional labor positively correlated with the turnover intention. 3) Hrarchical multiple regression analysis showed work environment, ages, assign ward, period in current hospital, emotional labor significantly influenced turnover intention in hospital nurses. Conclusion. These findings can be utilized to development of strategies to improving the work environment, managing the emotional labor for decreasing turnover intention of hospital nurses so that can be long time.

Pearson's correlation coefficient and Vector similarity are generally applied to The users' similarity weight of user based recommender system. This study is needed to find that the correlation coefficient of similarity weight is effected by the number of pair response and significance probability. From the classified correlation coefficient by the significance probability test on the correlation coefficient and pair of response, the change of MAE is studied by comparing the predicted precision of the two. The results are experimentally related with the change of MAE from the significant correlation coefficient and the number of pair response.

This paper proposes an algorithm to sense orthogonal frequency-division multiplexing (OFDM) signals in cognitive radio (CR) systems. The basic idea behind this study is when a primary user is occupying a wireless channel, the covariance matrix is non-diagonal because of the time domain cross-correlation of the cyclic prefix (CP). In light of this property, a new decision metric that measures the power of the data found on two minor diagonals in the covariance matrix related to the CP is introduced. The impact of synchronization errors on the signal detection is analyzed. Besides this, a likelihood-ratio test is proposed according to the Neyman-Pearson criterion after deriving probability distribution functions of the decision metric under hypotheses of signal presence and absence. A threshold, subject to the requirement of probability of false alarm, is derived; also the probabilities of detection and false alarm are computed accordingly. Finally, numerical simulations are conducted to demonstrate the effectiveness of the proposed algorithm.

The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.
