This research aimed to observe adolescent children's use of time and to discover the parent-related factors that affect adolescent children's use of time. The subjects included 2,092 fourth-grade elementary school students and 2,108 first-grade middle school students. We used data from the Korean Children and Youth Panel Survey. We tested sociodemographic factors, parents characteristics, and time usage, and we studied these factors using SPSS version 23.0; the results are as follows. Firstly, in the subordinate scope of the child-rearing attitude of parents, affection fourth-grade elementary school students(M = 1.83) and first-grade middle school students(M = 2.02). Inconsistency had an effect on fourth-grade elementary school students(M = 1.99), and first-grade middle school students(M = 2.12). Excessive expectations had an effect on fourth-grade elementary school students(M = 2.40) and first-grade middle school students(M = 2.55). Over-involvement had an effect on fourth-grade elementary school students(M = 2.68)and first-grade middle school students(M = 2.80). Finally, giving reasonable explanations had an effect on fourth-grade elementary school students(M = 1.51)and first-grade middle school students(M = 1.68). Secondly, in fourth-grade elementary school students(M = 463.35) and first-grade middle school students(M = 378.75). Further, studying hours during weekdays had an effect on fourth-grade elementary school students(M = 456.15) and first-grade middle school students(M = 460.86). Free activity hours during had an effect on fourth-grade elementary school students(M = 390.54) and first-grade middle school students(M = 387.11). Sleeping hours during holidays had an effect on fourth-grade elementary school students(M = 544.85) and first-grade middle school students (M = 511.74). Studying hours during holidays had an effect on fourth-grade elementary school students (M = 484.86) and first-grade middle school students (M = 511.74). Free activity hours during holidays had an effect on fourth-grade elementary school students(M = 518.68) and first-grade middle school students(M = 509.73). Thirdly, by observing the relative influence of related factors on adolescent children's use of time, grade(${\beta}$ = -.284), gender(${\beta}$ = -.208), over-involvement(${\beta}$ = -.380), supervising(${\beta}$ = -.217), and (${\beta}$ = .243) in terms of the child-rearing attitudes of parents was found to affect study hours($F=2.595^{**}$). The education level of fathers(${\beta}$ = -.144) results in(${\beta}$ = 1.991) and longer free activity hours for children($F= 4.116^{***}$). This research can be used to study the influence of parents'child-rearing attitudes on adolescent children's use of time and to suggest the role of parents in adolescents' ability to manage time effectively using practical.

Purpose: Purpose: The prognostic factors of non-operative management (NOM) in high-grade spleen injuries have been extensively studied, but factors that would help treatment decisions are lacking. We compared the characteristics of the patients to identify the factors affecting treatment choices. Methods: This is a review of 207 blunt spleen injury patients from January 2004 to December 2013. We compared clinical features and mortality between surgery and NOM, and used multivariate regression analysis to find the factor most strongly associated with prognosis. Results: Of the 207 patients, 107 had high-grade spleen injury patents (grade III or above). Of these, 42 patients underwent surgery and 65 patients underwent NOM. The mortality was 7% following surgery, 3% with NOM. The amount of packed red blood cells transfused in the first 24 hours and spleen injury grade were associated with management type, and mortality was highly associated with activated partial thromboplastin time (aPTT) and spleen injury grade. Conclusions: The grade of spleen injury was associated with management and mortality, so correctly assessing the spleen injury grade is important.

This study was to investigate factors and disclose causal model of the scientific literacy competency about the motivation for science and the scientific literacy competency. The 3 grade university students and the 1 grade university students as pre-service elementary teachers were participated to questionnaire investigation. The data were analyzed by the factor analysis method and the structural equation model method, and the following results were obtained. First, the 3 grade university students and the 1 grade university students perceived the science interest factors and science usefulness factors as the motivation for science, and also revealed the scientific problem recognition factor and the scientific evidence use factor as the scientific literacy competency. Second, the science interest factor had a greater effect on the scientific problem recognition factor than the scientific evidence use factor in both the 3 grade and 1 grade university students. In the path from the science usefulness factor to the scientific problem recognition factor, the science usefulness factor of the 3 grade university students had a greater influence on the direct route to the scientific problem recognition factor than that of the 1 grade university students. In the path from the science usefulness factor to the scientific evidence use factor, the science usefulness factor of the 1 grade university students influenced more on the direct route to the scientific evidence use factor than that of the 3 grade university students.

Whether and when naturalistic or supernaturalistic explanations of the origins of sun and earth, humans, life and species change with development was explored in a questionnaire and interviews with 32 first graders and 32 second graders, and in a questionnaire with 34 third graders, 32 sixth graders and 38 eighth graders. Participants were also asked about factors affecting their explanations in the questionnaires. Even the first and second graders could consistently provide supernaturalistic or naturalistic explanations on both the origins of sun and earth, and of humans. There was an age-related developmental shift from supernaturalistic to naturalistic explanation. As for origins of species, most of the first and second graders held the spontaneous generationist explanation, and after the third grade their views divided into evolutionist and creationist explanations. Students' explanations of species origins were established by the sixth grade through a transitional stage in the third grade. At the first and second grade levels, books and the children's own reasoning mainly influenced the views of origins, whereas parents and school were not perceived as being important. For the third graders and higher-grade levels, several factors, including parents and religion, were perceived as being important. These results show that explanations of origins start to develop earlier than or during the first grade, and are established by the sixth grade; moreover, the formation of these views is affected by several factors in addition to development.

Purpose: The purpose of this study was to empirically test a model of associations linking locations and competition among nursing homes (NHs), mediated by facility grade and registered nurse (RN) turnover, on activities of daily living (ADLs) in Korean NHs. Methods: This study used a cross-sectional design to identify causal factors on NH residents' ADLs. Data were collected from June 2017 to August 2017. A disproportionate stratified cluster sampling method of NHs across Korea was used to gain representation. The collected data consisted of location and the Herfindahl-Hirschman Index (HHI), RN turnover rate, facility grade, and NH residents' ADLs. Results: All pathways affecting ADLs were not significant, and the effect on facility grade was significant in RN turnover (β = -.59, p < .001). RN turnover associated negatively with facility grade. In other words, the higher the RN turnover, the worse the facility grade. Conclusion: This study is the first to examine the impact of location and HHIs, mediated by RN turnover rate and facility grade, on NH residents' ADLs. To improve residents' ADLs, subsequent studies are needed to identify the factors affecting ADLs utilizing other variables because this study did not identify factors that affect ADLs.

Background: Depending on various pathological factors, non muscle invasive bladder cancer (NMIBC) shows varying degrees of recurrence. The aim of this study was to determine the incidence of recurrence of NMIBS in our centre, study the influence of intrinsic tumour characteristics like grade, stage, size and number, and compare our results with data in the published literature. Materials and Methods: A hospital based retrospective study was conducted on patients who underwent treatment for NMIBC from 2011 to 2014. The factors studied were number, size, grade, stage and site for correlation with recurrence. Statistical analysis was performed using Medcalc version 12, using Pearson's Chi square test to ascertain associations between variables. Results: A total of 73 patients with NMIBC were studied of which 48 (65.8%) had low grade and 25 (34.2%) had high grade tumours. Some 38 patients (52.1%) had Ta tumours, 34 (46.6%) had T1 and one had CIS. Mean follow up was 34.3 months. Recurrence rates were found to be 33.3% in low grade and 52.0% in high grade tumours. The overall recurrence rate in our centre was 39.7%. Significant correlations were seen between stage and recurrence, with a rate of 15% for Ta and 63.3% for T1 tumours. Fourteen out of 21 bladder cancers (66.6%) with multiple tumours demonstrated recurrence (p=0.006). Grade, size and site had no influence. Conclusions: In our study, recurrence of NMIBC was found to be directly proportional to stage and number of primary tumours, but not grade, size and site. The incidence of recurrence of NMIBC both stage wise and grade wise in our centre was also low compared to the data in the published literature.
