Purpose: Hospital-acquired infections, common in developing countries, are a leading cause of morbidity and mortality. This study was done to examine the effects of organizational culture and awareness of infection control on nursing practice of infection control by nurses working in emergency departments.Methods: This descriptive correlational study was conducted with 135 nurses from the emergency department of a hospital. Data were collected from December 23, 2019, to January 14, 2020, using a structured questionnaire. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression analysis with SPSS/WIN 18.0.Results: The mean score of organizational culture, awareness, nursing practice of infection control were 5.56±0.78 out of 7, 4.66±0.36 out of 5 and 4.51±0.38 out of 5, respectively. The multiple regression analysis demonstrated that awareness and organizational culture of infection control accounted for 43% of the nursing practice of infection control.Conclusion: Study findings showed that there is a significant correlation between organizational culture, awareness, and nursing practice of infection control in the emergency department. Therefore, to improve nursing practices infection control in the emergency department, efforts should be made to promote infection control by developing education programs that can improve infection control awareness as well as strategies for a positive organizational culture.

Fermentation Time

Flushing and fermentation times are the two main parameters determining the quality of black tea. In this research, the effects of different flushing and fermentation times were studied on the quality of black tea in two clones, 100 and natural Chinese hybrid. Analysis of variance showed there were the significant differences between the clone types, flushing and fermentation times for theaflavin, thearubigin, total color, brightness, tannin and caffeine. Correlation coefficients between all studied traits, except thearubigin and brightness, caffeine and brightness, and total colour and theaflavin/thearubigin ratio, were significant at 1% probability. Regression analysis indicated there was a significant linear regression between fermentation time and brightness, tannin, and theaflavin/thearubigin ratio. Also, multiple regression analysis for brightness and total colour indicated that more than 70% of the variation in brightness was explained by theaflavin, caffeine and theaflavin/thearubigin ratio, and more than 68% of the variation in total colour was because of caffeine and theaflavin/thearubigin ratio.

<p>The purpose of this study is to investigate attitudes towards peace with respect to subjective wellbeing and gender. The participants of the study were 240 students who were taking their high school education in Kocaeli. Two different inventories were applied to the students; Adolescent Subjective Wellbeing Inventory and Peace Attitudes Scale. Multiple regression analysis was used to investigate if and to which degree subjective wellbeing predicts peace attitudes. To examine the relation between peace attitudes and gender, independent sample t-test was conducted. The results indicated that the peace attitudes of adolescents does not change according to gender (t238= -.153; p&gt;.05). According to the Pearson correlation coefficients, there is positive relations ranged from .30 to .65 between peace attitudes and four subscales of subjective well-being (p&lt;.001). The multiple regression analysis that was held to investigate the predictor role of subjective wellbeing on peace attitudes revealed that family relations satisfaction and positive feelings explains peace attitudes significantly (R<sup>2</sup>= .48 ; F reg= 53,468; p&lt; .001).</p><p> </p><p><strong>Özet</strong></p><p>Bu çalışmanın amacı, lise öğrencilerinin barışa yönelik tutumlarının öznel iyi oluş (aile ilişkilerinde doyum, önemli diğer kişilerle ilişkide doyum, yaşam doyumu, olumlu duygular) ve cinsiyet açısından incelenmesidir. Araştırma verileri, 2014-2015 Eğitim ve Öğretim Yılı'nda Kocaeli ilinde üç lisede eğitim gören 14-16 yaşları arasında 240 öğrenciden toplanmıştır. Araştırma verileri kişisel bilgi formu, ergen öznel iyi oluş ölçeği ve barışa yönelik tutumlar ölçeği ile toplanmıştır. Araştırmada veri analizinde cinsiyete göre barışa yönelik tutumların değişip değişmediğini test etmek için t-testi yönteminden yararlanılmıştır. Bulgulara göre, kız (X=16.297) ve erkek (X=16.356) öğrencilerin barışa yönelik tutumları arasında anlamlı bir fark bulunmamaktadır (t238=-.153; p&gt;.05). Değişkenler arasındaki ilişki pearson korelasyon katsayısı ile incelendiğinde, barışa yönelik tutumlar ile öznel iyi oluşun dört alt boyutu arasındaki korelasyonların .30 ile .65 arasında değiştiği gözlenmiştir (p&lt;.001). Öznel iyi oluşun barışa yönelik tutumlarını açıklayıp açıklamadığını incelemek için yapılan çoklu regresyon analizi sonuçlarına göre ise öznel iyi oluşun aile ilişkilerinde doyum ve olumlu duygular alt boyutlarının barışa yönelik tutumlar üzerinde açıklanan varyansa katkısının anlamlı olduğu sonucuna ulaşılmıştır.

Introductory Textbooks

In a field study, 180 naive students evaluated a randomly assigned chapter in an introductory textbook as to its interest level, enjoyableness, persuasiveness, credibility, capacity for teaching, and its potential to encourage more reading. Next the chapters were content analyzed by 90 pairs of students for humor content. Following the content analysis, 90 correlation coefficients were computed between the frequencies and types of humor utilized within the chapters and the students' evaluations of those chapters. A stepwise multiple regression analysis was also performed. The analyses indicate that, while use of humor is significantly related to the enjoyment of a text, it is not strongly related to interest, persuasiveness, capacity for learning, nor capacity to read more. Also, amount of humor was significantly negatively related to author's credibility.

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.
