This study examined the relations between parents' reactions to their preschool child's negative emotions, coping styles, and peer acceptance. Subjects were 250 5-year-old preschoolers and their parents. Instruments were the Coping with children's Negative Emotions Scale, and coding strategies checklist and peer rating scales for children. Data were analyzed with the SPSS PC + program. Parent's emotion-focused reactions, encouragement of expression and problem-focused reactions were positively associated with both peer acceptance and child coping styles whereas parent's distress, and punitive and minimizing reactions were associated with lower Peer acceptance and child coping styles of venting, denial, aggressive action, and avoidance. In child coping styles, problem solving was positively associated with peer acceptance while aggressive action anti venting were associated with a lower level of peer acceptance. Problem solving tended to be positively associated with peer acceptance, whereas aggressive action and venting tended to be associated with lower level of peer acceptance. (4) There was a statistically significant relations among parent's reactions to preschoolers' negative emotions, preschoolers' coping styles, and peer acceptance. There were the positive relations among parent's supportive reactions preschoolers' coping styles of problem solving and seeking support, and peer acceptance.

In this paper we obtain the complete convergence of weighted sums of asymptotically almost negatively associated random variables. Some previous known results for negatively associated random variables are generalized to asymptotically almost negative association case.

본 연구는 보건계열 대학생의 부정정서 극복력과 대학생활 스트레스, 스트레스 반응 관계에서 매개효과를 검증하고자 시행하였다. 연구의 방법으로는 경상남도 소재의 보건계열 대학생 284명을 대상으로 설문조사를 시행하였다. 자료의 분석은 SPSS 22.0 프로그램을 이용하여 빈도분석, 상관분석, 회귀분석을 실시하였다. 연구 결과는 다음과 같이 나타났다. 보건계열 학생의 부정정서 극복력은 평균 4.49로 나타났으며 대학생활 스트레스는 2.74로 나타났다. 스트레스 반응에 대해서는 공격성 반응이 1.76으로 가장 낮았고, 피로반응이 2.71로 가장 높았다. 부정정서 극복력과 스트레스 반응, 대학생활 스트레스의 관계를 상관분석 한 결과, 부정정서 극복력은 대학생활 스트레스, 스트레스 반응과 부적상관을 이루는 것으로 나타났다. 부정정서 극복력은 스트레스 반응을 완화시키는 과정을 통해 대학생활 스트레스를 해소하는 것으로 나타났으며 스트레스 반응 하위요인에서도 매개효과를 가지는 것으로 나타났다. 따라서 본 연구에서는 극복력은 대학생활 스트레스와 그에 따른 반응에 영향을 미치고 있는 것으로 보인다. 그러므로 보건계열 대학생 중 대학생활 스트레스에 노출되어 있는 학생에게는 부정정서 극복력이 스트레스 반응을 완화시키는 방법이 될 수 있으며, 스트레스 반응의 하위요인에 받는 적절한 스트레스 완화방법이 요구되어 진다.

This study was undertaken to determine whether the presence of fertility-associated antigen (FAA) in semen would influence semen characteristics and conception rate of artificial insemination in Hanwoo. The response to FAA of 36 heads of proven bull, 7 heads of young bull, and 27 heads of performance-tested bull was that one proven bull was FAA-negative and the others were FAA-positive, therefore FAA-negative bull was 1.4%. FAA-negative bull was lower in first and second semen concentrations than those of FAA-positive bull in 5,301 semen of 21 heads of proven bull, then FAA-negative bull was fewer as 11.5% in total sperm counts. The estrus of 22 heads was 70d-nonreturned in 36 cows first inseminated with frozen semen of FAA-negative bull, but that of 249 heads in 378 cows first inseminated with frozen semen of FAA-positive bull. Each conception rate was 61.1% and 65.9%, respectively. The difference of conception rates was 4.8%. These results indicate that the response of FAA to semen were influenced semen characteristics and conception rate of artificial insemination, but further investigations are needed to confirm the results.

In this paper we prove the almost sure convergence of partial sums of identically distributed and negatively associated random variables with infinite expectations. Some results in Kruglov[Kruglov, V., 2008 Statist. Probab. Lett. 78(7) 890-895] are considered in the case of negatively associated random variables.

We prove a central limit theorem for the negatively associated random variables in a Hilbert space and extend this result to the linear process generated by negatively associated random variables in a Hilbert space. Our result implies an extension of the central limit theorem for the linear process in a real space under negative association to a simplest case of infinite dimensional Hilbert space.

Let {$X_{ni}$, $i{\geq}1$, $n{\geq}1$} be an array of rowwise asymptotically negatively associated random variables and {$a_{ni}$, $i{\geq}1$, $n{\geq}1$} an array of constants. Some results concerning complete convergence of weighted sums ${\sum}_{i=1}^{n}a_{ni}X_{ni}$ are obtained. They generalize some previous known results for arrays of rowwise negatively associated random variables to the asymptotically negative association case.

Some conditions on the strong law of large numbers for weighted sums of negative quadrant dependent random variables are studied. The almost sure convergence of weighted sums of negatively associated random variables is also established, and then it is utilized to obtain strong laws of large numbers for weighted averages of negatively associated random variables.

Purpose: This study was conducted to determine the neighborhood environmental factors associated with physical activity among adults living in rural communities. Methods: A cross-sectional descriptive survey was conducted with a convenience sample of 201 adults living in three Ri in Y-city, Gyeonggi-do. Data were collected from face-to-face interview by trained interviewers and were analyzed using a zero-inflated negative binominal regression model. Results: Participants reported engaged in moderate or vigorous physical activity was 76.1%; 10.5% of participants reported that they met moderate physical activity recommendations and 14.5% of participants reported that they met vigorous physical activity recommendations. Zero-inflated negative binominal regression analysis showed association of increasing days of physical activity with social cohesion (${\beta}=.130$, p=.005), social network (${\beta}=-.096$, p=.003), and safety for crime (${\beta}=-.151$, p=.036), and no days of physical activity was associated with no attainment of education and marginally associated with increasing BMI. Conclusion: Neighborhood environmental factors including social cohesion, social network, and crime for safety were significantly associated with physical activity of rural adults. Community health nurses should expand an approach for individual behavior change to incorporate rural adults' specific neighborhood environmental factors into physical activity interventions.

For bounded negatively associated random variables we derive almost sure convergence and specify the associated rate of convergence by establishing exponential inequality.
