The aim of this study was to investigate the effect of perceived self-regulation levels on target commitment of secondary school students participating and no-participating in inter-school sports competitions. “General Information Form”, “Perceived Self-Regulation Scale (PSRS) and “Goal Commitment Scale (GCS)” were used to collect the data. The sample group consisted of 313 (male = 130, female = 183) students studying at secondary level. Pearson Moment Correlation test, Manova analysis and simple linear regression analysis were used for data analysis. As a result of the analysis, the main effect of the variables of gender and participating in inter-school sports competitions was not determined to be statistically significant for PSRS and GCS. As a result of the regression analysis, it was determined that perceived self-regulation predicted the target commitment positively and statistically significant. Also, it was determined that there was a positive and significant difference between PSRS and GCS. In this study, it was determined that participating in inter-school sports competitions did not significantly affect perceived self-regulation and target commitment levels. It is recommended that the study should be applied to students who do regular sports and students who do not do regular sports.

The main objective of this study is to examine the possible relationship between democratic values, problem-solving skills, and attitudes toward violence. In addition, it studies whether democratic values, problem solving skills and the tendency of attitudes toward violence differ according to different variables. Descriptive model was used in the research. The study group of the study consisted of a total of 326 students, 172 female and 154 male selected by appropriate sampling from three middle schools in Konya. It was used Basic Democratic Values Questionnaire, Problem Solving Inventory for Children, and the Adolescents' Attitudes Toward the Violence in the study. While the data were analyzing, t test, ANOVA test, Pearson Moment Product Correlation analysis and simple linear regression analysis were used. When the data obtained from the research were examined, there was a significant difference in the level of attitudes toward violence according to the gender variables. There was a significant difference in problem solving skills and attitudes toward violence according to grade variables. Pearson's correlation analysis revealed statistically significant and negative relationship between democratic values, problem-solving skills, and attitudes toward violence. As a result of simple regression analysis, democratic values have predictive role on problem solving skills; it is seen that problem-solving skills are important variables in the tendency towards violence.

The Relationship

This study aimed to investigate the relationship between children's prosocial behavior and self-regulation skills. To collect the data of the study, demographic information form developed by the researcher was used for the demographic information of children, the prosocial behavior sub-dimension of the social behavior scale was used for the prosocial behavior, and the self-regulation skills scale was used for the self-regulation skills of the children. The collected data were analyzed by independent sample t-test, Pearson’s product moment correlation analysis and simple linear regression analysis in a computer package software. As a result of the research, while the self-regulation and prosocial behaviors of children differed according to gender and age of children, the situation of the children whether they have siblings and duration of the pre-school education did not make any significant difference. According to these results, girls' self-regulation and prosocial behavior scores were higher than that of boys and 6 years of age children’s scores were higher than that of 5 years of age children. While there was a moderate positive significant relationship between self-regulation skills and prosocial behavior, it was concluded that the prosocial behavior of children predicted self-regulation skills at the level of 11%.   Keywords: Prosocial behavior, self-regulation skills, early childhood, preschool

Abstract Background There are controversies about platelet-rich plasma (PRP) as an established treatment option for rotator cuff (RC) tendinopathy. The purpose of the study was to find the relation of cellular component with clinical efficacy in RC tendinopathy and to find the composition of PRP in treating RC tendinopathy. Methods A total 30 patients were recruited and divided into PRP and control groups. In the PRP group, 2 ml of PRP solution was injected to the hypoechoic lesion of degenerative supraspinatus via 22-gauge syringe with peppering technique. Patients in the control group were taught rotator cuff strengthening exercises. American Shoulder and Elbow Surgeons (ASES), Constant-Murley score, and numeric rating scale (NRS) were measured before, 6 weeks after, 12 weeks after, and 24 weeks after the procedure. PRP compositions were analyzed using the 1 ml of PRP solution. Results Linear regression analysis showed no significant difference of ASES and Constant-Murley scores between the groups at 6 weeks (P = 0.582 and 0.258) and at 12 weeks (P = 0.969 and 0.795) but showed a significant difference at 24 weeks (P = 0.050 and 0.048). Independent t test showed significant group difference of NRS at 6 weeks (P = 0.031) but not at 12 and 24 weeks (P = 0.147 and 0.935). 5.19 pg/ml in IL-1β and 61.79 μg/ml in TGF-β1 were acquired as cutoff values to predict meaningful improvement. The PRP subgroup above IL-1β or TGF-β1 cutoff value showed significant differences in all clinical outcomes compared with the exercise group while the PRP subgroup below the cutoff value showed no significant differences in linear regression analysis. Conclusions Our study can help to find the optimal PRP condition and to enhance the effect of PRP on RC tendinopathy. Trial registration All the patients were registered in our Institutional Ethics Committee (approval number 2014-05-009).

Objective The study aimed to describe the frequency and associations of the number of medical visits for the violent victimization and mental health problems in adolescents in South Korea.Methods In 2017, 62,276 middle and high school students participated in the thirteenth Korea Youth Risk Behavior Web-based Survey (KYRBS). The frequency of violence victimization during the last 12 months was measured. The collected data were analyzed by applying descriptive statistics, chi-square tests, multiple linear regression, and logistic regression analysis, using the SPSS 22.0. The data were weighted to generate national estimates.Results Among the respondents (sample size=62,276, weighted=3,027,488), 3.7% of boys and 1.7% of girls had experienced being treated by a doctor due to violence during the recent past 12 months. In multiple linear regression analysis, feelings of sadness or hopeless, suicide ideation, suicide plan, suicide attempt were positively associated with violence victimization (F=32656.037, p<0.001) dose response.Conclusion The results found cross-sectional evidence that violence victimization was associated with higher suicide behavior and depressed mood. The victims of violence should be referred follow-up for physical and psychological issues. Also, a policy including the first responders and medical staffs should be initiated.

Abstract PurposeImplementation and comparison of non-invasive dynamic and static whole-body (WB) [18F]NaF PET/CT scan methods to replace invasive bone biopsy, used for quantitative analysis of bone clearance in patients with chronic kidney disease - mineral and bone disorder (CKD-MBD).MethodsSeventeen patients with CKD-MBD underwent a 60-minute dynamic scan followed by a 30-minute static WB scan. Tracer kinetics in four thoracic vertebrae were analyzed using non-linear regression and Patlak analysis using image-derived arterial input functions. We validated the use of a semi-population input function in this population.ResultsSkeletal plasma clearance (Ki) from Patlak analyses correlated well with non-linear regression analysis, but Ki-results using Patlak analysis were lower compared to Ki-results using non-linear regression analysis. However, no significant difference was found between Ki obtained by static WB scans and Ki obtained by dynamic scans using non-linear regression analysis (p=0.29). ConclusionOur results show good correlation between dynamic and static analysis of skeletal plasma clearance with no significant difference between the Ki-results obtained by non-linear regression analysis and the more clinically suitable static scan analysis method. We found lower Ki-results when Patlak analysis was applied. Thus, WB [18F]NaF PET/CT scans can be applied in future studies to measure Ki in CKD-BMD patients, but the results should not be compared uncritically with results obtained by dynamic scans analysis.
