Objective: Bruxism is a jaw muscle activity disorder characterized by clenching or grinding of the teeth and can be seen in both children and adults. The purpose of this study is to evaluate the parental knowledge about bruxism in children. Methods: A cross-sectional study was conducted with 265 parents whose children were attended at University of Mersin pediatric dentistry and oral and maxillofacial surgery clinics. Children’s ages varied from 6 months to 16 years old. A 20-questioned questionnaire was used to collect the data. IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) program was used for the analysis. Re . . .sults: A total of 265 parents (159 were female and 106 were male) participated in the study. The majority of the parents were between the ages of 31-40 (60.8%). The rate of clenching and grinding of teeth during sleep (21.5%) was higher than the rate when they were awake (7.2%). The ratio of the parents seeking treatment for their children because of this harmful habit was very low (3.8%). The majortiy of parents (37.7%) reported that they seek help from dentists. The participants believed that bruxism was associated with dental problems (33.6%) and emotional factors (32.8%). A significant difference was found between the educational background of the parents and the ability to define bruxism. Conclusion: Parents had inadequate knowledge about bruxism in children and this was mostly related to the educational background of the parents. Objetivo: El bruxismo es un trastorno de la actividad muscular de la mandíbula que se caracteriza por apretar o rechinar los dientes y se pueden ver tanto en niños como en adultos. El propósito de este estudio es evaluar el conocimiento de los padres sobre el bruxismo en sus niños. Métodos: se realizó un estudio transversal con 265 padres cuyos hijos fueron atendidos en las clínicas de Odontología Pediátrica y Cirugía Oral y Maxilofacial de la Universidad de Mersin.

The purpose of this paper was to investigate the validity of the environmentalKuznets curve (EKC) hypothesis for the period between 1977 and 2013 by using the sub-elements of carbon (CO2) emissions in China. To this end, the fully modified ordinary leastsquares and pairwise Granger causality methodologies have been employed. As a result, itis found that financial development leads to an improvement in environmental performancein China for many kinds of pollution, including the following: liquid fuel pollution, solidfuel pollution, residential buildings and commercial and public services pollution, andelectricity and heat production po . . .llution. The findings indicate that an increase in percapita consumption of energy will lead to an increase in eight different sub-elements of thecarbon emissions. The highest impact is for per capita CO2emissions and the lowestimpact is for liquid fuel CO2emissions. The findings also suggest that the EKC hypothesisis valid for CO2emissions from gaseous fuel consumption, liquid fuel consumption, solidfuel consumption and transportation. However, the EKC hypothesis is not valid foraggregate CO2emissions, CO2emissions from residential buildings and commercial andpublic services, from electricity and heat production and from manufacturing industriesand construction Daha fazlası Daha az

Background: This study aimed to determine risk factors that occurrence time of traffic accidents. Traffic accident occurrence time is defined as the time between a driver’s getting his/her license and having the first accident, involving death or injury between 2008-2012 and there were investigated. Methods: This study was conducted with the Cox Regression and life tables models included among survival analysis models. Data of all 11.671 traffic accidents in Kayseri in Turkey were analyzed for the 5-yr period. Results: The non-occurrence rate of traffic accidents involving injury is mostly affected by gender, age, education, number . . .of vehicles involved in accident, road surface material, daylight, type of road, direction of road and time of the day. The non-occurrence rate of fatal traffic accident duration is mostly affected by gender, age, education, daylight and horizontal alignment. The rate of having an accident involving death or injury after getting driver's license is 30.3% in the first 5 yr, it is 50.1% in the first 10 yr and 91.7% in 25 yr. Conclusion: As the non-occurrence time increases, occurrence of accidents in earlier years will decrease. In other words, the number of accidents in earlier years will be lower. This will cause a decrease in the number of accidents in total Daha fazlası Daha az

In urban planning, housing evaluation of residential areas plays a critical role in promoting economic efciency.Tis study produced an evolutionary-based map through the combination of hybrid Multicriteria Decision Making (MCDM) and Geographical Information System (GIS) by assessing suitability of housing location. Suitable locations were modelled and determined with the present study from very low suitability to very high suitability. In the frst stage, Fuzzy DEMATEL (the Decision Making Trial and Evaluation Laboratory) and Covariance Matrix Adaptation Evolutionary Strategy (CMA-ES) under fuzzy conditions as a subjective and an obje . . .ctive (model-based) technique, respectively, were employed to fnd the weights of criteria which are critical part of decision making. In the second stage, housing evaluation map for these two approaches was drawn and their performances were classifed and measured with WLC (Weighted Linear Combination) method. 29 criteria determined were prioritized as per judgment of urban planning and real estate experts for Fuzzy DEMATEL and CMA-ES. Afer having been coded to MATLAB for obtaining optimum weights in CMA-ES, all collected data for 160 houses were mapped as vectorial (positional) and transformed to raster (pixel) data by getting entered in ArcGIS 10.4 sofware. We achieved CMA-ES-WLC maximization values for 104 alternatives with (positive value) 65% performance, but we obtained FDEMATEL-WLC maximization values for 56 alternatives with (negative value) 35% performance. WLC values calculated with CMA-ES and FDEMATEL weights allowed us to conclude that the houses with the highest suitability in terms of investment are in Alpaslan, K¨os¸k, and Melikgazi streets. Te result shows that the methodology used in the application of this study performed in Turkey is an important and powerful technology in providing decision support for spatial planning Daha fazlası Daha az

Son yıllarda çeşitli alanlarda yaşanan değişimler, bireylerin günlük hayatlarını olduğu kadar çalışma hayatlarını da olumlu ve olumsuz yönde etkilemektedir. Bu olumsuz etkilenmenin bir sonucu olarak meydana gelen tükenmişlik kavramı, yaşanan stres sonucu enerjide tükenme meydana gelmesi ve insanlar ile sürekli etkileşimde bulunmanın yarattığı duygusal tükenme, duyarsızlaşma ve düşük kişisel başarı hissi olarak tanımlanmaktadır. Dolayısıyla tükenmişlik; duygusal tükenme, duyarsızlaşma ve düşük kişisel başarı hissi olmak üzere üç boyuttan oluşmaktadır. Duygusal tükenme, bireyin duygusal ve fiziksel kaynaklarında azalmayı ifade ederken . . .; duyarsızlaşma, duygudan yoksunlaşmayı, olumsuz tutumları ve işe karşı tepkisizleşmeyi belirtir. Düşük kişisel başarı hissi ise, kişinin kendisini olumsuz değerlendirme eğiliminde olmasını ifade eder. Bu araştırmanın temel amacı, çalışanların tükenmişlik düzeylerinin, yöneticilerinin cinsiyetine göre farklılaşıp farklılaşmadığını belirlemektir. Bu kapsamda, kolayda örnekleme yöntemi ile seçilen 187 kişilik bir grup üzerinde anket çalışması yapılmıştır. Anket formu iki bölümden oluşmaktadır. Birinci bölümde, tükenmişlik düzeyini ölçmeye yönelik olarak Maslach Tükenmişlik Envanteri kullanılmıştır. İkinci bölümde ise, demografik sorular yer almaktadır. Verilerin analizi için t testi ve ANOVA analizleri kullanılmıştır. Araştırma sonucuna göre, çalışanların tükenmişlik düzeylerinin, yöneticilerinin cinsiyetine göre farklılık gösterdiği tespit edilmiştir. Ayrıca medeni hal, mesleki deneyim ve kurum türüne göre tükenmişlik düzeyleri arasında da farklılıklar ortaya çıkmıştır. Diğer demografik değişkenlerden yaş, cinsiyet ve eğitim durumu ile tükenmişlik düzeyleri arasında anlamlı farklılıklar tespit edilememiştir. In recent years, the changes that have taken place in various fields have affected the daily life of individuals as well as their work life in the positive and negative aspects. The concept of burnout as a consequence of this adverse effect is defined as emotional exhaustion, depersonalization, and low personal accomplishment that are caused by exhaustion of the ending stress in life and constant interaction with people. So burnout consists of three dimensions: Emotional exhaustion, depersonalization, and low personal accomplishment. Emotional exhaustion refers to the decrease in the emotional and physical resources of the individual. Depersonalization refers to emotional deprivation, negative attitudes, and unresponsiveness to work. A sense of low personal accomplishment means that the person tends to evaluate himself negatively. The main purpose of this research is to determine whether the burnout levels of employees differ according to the gender of the managers. Within this scope, a questionnaire study was conducted on a group of 187 people who were easily selected by sampling method. The questionnaire consists of two parts. In the first part, the Maslach Burnout Inventory was used to measure the burnout level. In the second part, there are demographic questions. For the analysis of the data, t test and ANOVA analyzes were used. According to the results of the research, it was determined that the burnout levels of the employees differ according to the genders of the managers. In addition, there were differences among the levels of burnout according to working time, professional experience and institutional type. No significant differences were found between age, marital status, educational status and burnout levels among other demographic variables Daha fazlası Daha az
