The relationships and differences between organizational learning and the performance of teachers in five public educational institutions in a district of Lima were determined. It was a quantitative study with a comparative correlational, non-experimental design. 145 teachers were surveyed with two validated questionnaires. The Tau-b-Kendall correlation test was used for correlation analysis. For score comparisons, the normal Z test, analysis of variance and a Scheffe test were used. Significant associations were found between the variables, and it was also determined that there were differences between the average scores of the teachers by educational level (initial, primary and secondary), with greater associations between teachers at the initial and secondary levels. Finally, the promotion of learning is an aspect that would require greater attention for the better performance of regular basic education teachers, and more aggressive strategies should be established from the institutional directions to promote more and better organizational learning as a work philosophy in these professionals in a social context where knowledge and technology interact at the level of mimicry in a structure that requires competitiveness at the human evolutionary level.

This paper aims at measuring the extent of some translation students' competence of grammatical aspect compounds (strings) and their adequacy in rendering them in English. It also tries to establish which strings students tend to mistranslate. The researchers designed a multiple-choice test, using Google form, in which a given Arabic text is provided with four alternatives: one correct answer and three distractors. The test was distributed to students from translation departments at Yarmouk University and the German Jordanian University enrolled in the second semester, 2020 via the E-learning systems. Responses of students (202 out of 300 from YU and 63 out of 86 from GJU) were collected in tables. The researchers used One-way ANOVA and Scheffe Test to analyze the data. The paper has concluded that there are no significant differences among students with regard to gender, study plan, level of study, and taking Arabic courses traditionally taught. However, students joining Yarmouk University and the German-Jordan University from international and private schools are better than those coming from public schools. The majority of students do not have problems with the simple present and simple future and their perfective and progressive aspects, nor do they with past perfect. However, they confuse the perfective and progressive aspects of the simple present and the simple past. Keywords: Grammatical aspects, Arabic grammar, English grammar, Translation Yarmouk University, German-Jordanian University.

The purpose of this study is to comprehensively understand the effect of extra feeding activities and parenting on children's independence. The method used in this study is an experimental method with children's independence as the main problem which is the dependent variable. In this study the sampling technique that will be used is multistage cluster sampling. The sample in this study was in two elementary schools namely SDN 4 Banjar Agung and SDN 5 Banjar Agung, researchers only chose students based on the results of questionnaires parenting parents based on authoritarian, permissive, democratic parenting categories and 10 students each so that the sample in this study was 30 students as a control class at SDN 4 Banjar Agung and 30 students as experimental classes at SDN 5 Banjar Agung. This research is an experimental design with 2x3 factorial design. Therefore, data analysis used a two-way ANOVA, if differences were tested, followed by the Tukey test or Scheffe test to determine which one was higher. From the findings, it can be recommended to use extra feeding activities with fun cooking to increase children's independence.

In this study, it was aimed that the comparison of indiviuals over 50 who have played football and the same age group of sedentary individuals‟ quality of life Totally, 100 individuals have participated in the study who live in Afyonkarahisar some of whom have played football over 50 and individuals who do not do regular physical activities that we accept sedentary ones at the same age. Personal Information Form, International Physical Activity Survey and in order to assess the quality of life of study group The Scale of Quality of Life which was developed by WHO have been fulfilled by the participants As a result of the research the collected data have been analysed on the SPSS 25 programme, in order to determine the range of participants of research ,Kolmogorv-Smirnova analyzes have been applied and identifying the ranges are normal, independent sample t-test have been applied for pairs and for groups of individuals more than two , anova variance analysis has been put into practice. Scheffe test has been carried out in order to determine which groups have the significant difference among them. Consequently; It is estimated that married participants in comparison with singles, the ones who do exercises regularly in comparison with those who do not do, the ones who do exercises 5 days or more in a week in comparison with the ones who does less frequently,the ones who are so healthy in general in comparison with the ones who are not, the individuals who do physical activities intensively in comparison with the ones who do not do have a high quality of life.In this sense, individuals over 50 who have played football befor and after 50 and sedentary indiviudals differentiate in terms of quality of life and somehow it is concluded that individuals who do physical activities have a high quality of life in comparison with the other individuals. ​Extended English summary is in the end of Full Text PDF (TURKISH) file. Özet   Bu çalışmada 50 yaş üstü futbol oynamış bireyler ile aynı yaş grubu sedanter bireylerin yaşam kalitesinin karşılaştırılması amaçlanmıştır. Bu araştırmaya Afyonkarahisar ilinde yaşayan 50 yaş üstü futbol oynamış bireyler ile 50 yaş üstü sedanter olarak kabul ettiğimiz düzenli fiziksel aktivite yapmayan toplam 100 birey katılmıştır. Katılımcılara kişisel bilgi formu, uluslar arası fiziksel aktivite anketi ve araştırma grubunun yaşam kalitesini değerlendirmek için WHO ‘nun (1998) geliştirdiği Yaşam Kalitesi Ölçeği kullanılmıştır. Araştırma sonucunda elde edilen veriler SPSS25 programında analiz edilmiş, araştırmaya katılanların dağılımını belirlemek için frekans ve yüzde analizi, Kolmogorv- Smirnova analizleri yapılmış olup verilerin dağılımın normal olduğu belirlendikten sonra, 2’li grupların karşılaştırılmasında bağımsız örneklşem t-testi, 2’den fazla gruplar için tek yönlü Anova Varyans analizi yapılmıştır. Anlamlı farklılığın hangi gruplar arasında olduğunu belirlemek için Scheffe testi yapılmıştır. Sonuç olarak; evil olan katılımcıların bekar olanlara gore, düzenli bir şekilde spor yapanların yapmayanlara göre, haftada 5 gün ve üzerinde spor yapanların daha az sıklıkta yapanlara göre, 41 yıl ve üzerinde aktif spor yaşamı olanların daha az yıl spor yapanlara göre, genel sağlık durumu çok iyi olanların olmayanlara ve yoğun fiziksel aktivite yapan kişilerin yapmayanlara göre yaşam kalitesinin yüksek olduğu görülmüştür. Bu da 50 yaş üstü kişilerin 50 yaş öncesinde ve sonrasında futbol oynamış bireylerle sedanter bireylerin yaşam kalitesi açısından farklılıştığı ve bir şekilde fizksel aktivite yapmış kişilerin diğer bireylere göre yaşam kalitesinin yüksek olduğu sonucuna varılmıştır.

Abstract Background The Bronx (BX) is an urban city with the most poverty, least educated population and poorest health outcomes among 62 counties in New York State. Unsurprisingly, BX has the highest rates of COVID-19 diagnoses across New York City (NYC). Lincoln Medical Center (LMC) is part of the NYC health and hospital system (NYC H+H) and has the highest COVID-19 admissions in BX and the second-highest across NYC. Herein we report our preliminary data on mortality rate (MR) of hospitalized COVID-19 patients and discuss the disproportionate of MR across NYC. Methods On 26 April 2020, we acquired the total number of hospitalized COVID-19 and deaths and mechanically ventilated (MV) COVID-19 and death from LMC and all other NYC H+H. Scheffe test was used to determine MR differences. The P-value (p) < 0.005 was set as a statistically significant threshold. Results MR of our hospitalized COVID-19 patients was 31%, which is higher than that of Man (24%, p 0.001). However, LMC has a high proportion of MV COVID-19 (local and transferred cases). Sub-group analysis of non-MV COVID-19 showed LMC MR (6%) is lower than Brooklyn (BL) (17%, p 0.00) and Queens (Qu) (17%, p 0.00) and didn’t differ from Man NYC H+H centers (8%, p 0.68). Analysis of MR among MV patients between LMC and other NYC H+H centers across four boroughs did not discover any differences. Hospitalized COVID-19 MR from all NYC H+H centers in BX (28%) did not differ from Man (24%, p 0.7) and Qu (28%, p 0.99). Interestingly, we found that MR is the highest in BL (33%). Moreover, MR of non-MV COVID-19 was higher in BL (17%) and Qu (17%) than BX (10%) and Man (8%) NYC H+H centers. We hypothesize this may result partly from the tense and shortage of health care resources in these two boroughs, especially, at the beginning of pandemic so some critical patients may not receive adequate care such as delaying intubation. Further research investigating reasons for this disproportion will help in developing the best available care plan for the ongoing crisis. Percentage of COVID-19 Mortality in each group Multiple comparison by Scheffe Test of MR of hospitalized patients with COVID-19 at LMC and across 4 NYC boroughs Multiple comparison by Scheffe Test of MR of non-MV patients with COVID-19 at LMC and across 4 NYC boroughs Conclusion Despite the high COVID-19 incidence and poor epidemiologic health risks of the population in BX, MR of hospitalized COVID-19 seemed to be the same as Man and Qu, and surprisingly lower than BL. MR of non-MV COVID-19 in BX is lower than BL and Qu. The studies determining the reasons underlying this disproportionate would be worthwhile. Disclosures All Authors: No reported disclosures

The Turkish educational system has been constantly changing over time. New systems are frequently introduced and when the results prove to be unsuccessful, a reversion of the former system emerges. Moreover, in order to identify ways and strategies to do this, it is also important to see the situation clearly and to decide the structure of support systems for principals. Survey design is used in this study. The population consists of principals of schools in the city of Istanbul in the academic year 2017–2018. The sample group consists of 161 principals from various public and private schools located on the European side of the city. Data were interpreted by % (percentage), t-test, one-way analysis of variance and the Scheffe test. The results indicate that the coping strategies, most commonly preferred by principals, are spending time with loved ones, building an optimistic perspective, and avoiding circumstances causing stress in order of importance. Keywords: Coping strategies, public and private schools, school principal, stress.
