Although it is estimated that appendicitis develops among 1% of the population under 15 years; it is stated that the most important factor that causes appendicitis is obstruction of lumen. The current study was cross-sectionally and descriptively undertaken in order to identify the descriptive characteristics of the children who had appendectomy surgery and the related factors.The population of the study was composed of the children aged 4-18 years who were hospitalized due to appendicitis at Bağcılar Training and Research Hospital Pediatric Surgery Service between 2012 and 2014. The sample of the population was consisted of a total of 64 children who accepted to participate in the study and stayed at the hospital during research period. The data were gathered using a questionnaire form designed by the researchers.37.5% of the participant children were girls and 62.5% of the participant children were boys; mean age was 11.48±3.48 years. Most of the mothers (60.9%) and fathers (60.9%) had primary school degree. 43.8% of the families had appendectomy previously, 95.3% did not have any chronic diseases. 25% of the children had a perforated appendix and most of them presented such symptoms as pain (70.3%), nausea * ADDRESS FOR CORRESPONDENCE: Birsen Bilgen Sivri, Mevlana University Health Services High School, Konya 42003, Turkey.

But studies show a high percentage of rejection of the prosthesis in this group. In clinical studies, there are not very different in function of children who use of prosthesis and those who do not. Answer to why children accept and use their prosthesis or reject it could help and improve the future design of the prosthesis and rehabilitation. The aim of this study was finding important criteria for children with below elbow amputation, their parents and therapists for acceptance and use of prosthetics or rejects it in children group. Method: This study was conducted by literature search of Science direct, Google Scholar, Cochran Library, MEDLINE and PubMed between 1966 and 2014 ,that investigated effective factors in accept or reject of below elbow prosthesis in below elbow amputee children.For quality assessment of articles we rated each paper using the Downs and Black score ranges and Pedro scale .

The prisoners and convicted, who participated in the study, were divided into four groups as training + brochures, brochures and control. The pre-prepared survey was conducted on the prisoners and convicted and the test, which had been prepared for determining the impact of nutrition behaviour and manner, was repeated in the beginning of the study (pre-test), at the end of the training (post-test) and one month later in order to evaluate the sustainability of nutrition training (monitoring test).

Due to the increase of demands for societies of health care day-to-day, the analysis of the elements which effect the usage of hospitals efficiently and effectively also comes into prominence. One of those is the phenomenon of “conflict”. Since hospitals are complex structures, the reasons of conflicts that may occur are so varied. There may sometimes be numerous reasons behind a conflict case at a unit. Emergency room is one of the units where the conflicts at hospitals frequently happen. In order to manage a conflict in emergency room, it comes into prominence to diagnose the conflict, to make the necessary intervention, and to bring out the reasons of the conflict.  In this case study, the conflict happens as a chain of events by taking a report of a nurse who will come to seizure without informing the other  responsible nurse and declaring to the other  responsible nurse that four colleagues of the other sentry nurse have not come. The reason of happening of the conflict is the manner of unclear  communication. The nurse who will not come to her seizure by taking a report does not inform that and she keeps her taking report secret. The conflict is terminated by win-win logic, a method of problem solving, of the responsible nurse and by participating of other workers in this issue. Mutual clear communication is used and the main reason of the problem is identified as “communication problem”. As a result, it is inferred that communication problems cause hindering work, forming a platform of conflicts, and wasting time. While the conflict is being terminated, communication problems between numerous people are removed by using correct communication ways and it is given a lead to obtain a better communication platform in the organization. Having less problems due to taking care of communication in emergency room after this event shows that this conflict has been resulted in positive outcomes.

The present study is designed to assess effect of individual and work-related risk factors on the WAI in one dairy factory.  Methods: This cross-sectional study was designed among 117 workers. Work ability was measured by the Persian versions of Work Ability Index (P-WAI). An author-developed measure was used to assess individual and work-related factors. All Statistical analyses were performed using IBM SPSS Statistics 21 (USA, SPSS Inc.).  Results: The mean age of participants was 32.38 ± 7.3 and the Mean score of the WAI was 44.92 ± 5.56. According to the categorical classification of WAI score, 10.9, 35.6, and 53.5 % of participants had moderate, good and excellent work ability, respectively. The results of statistical analyses showed that mean WAI significantly differed with age (0.049), sleep quality (p= 0.035) and employment status (p= 0.014).

Primary responsibility for the development and protection of public health isin the family then the health care team members and the social environment.  Hospitalization of a child is a stressful process both for the child and the family. In the literature, requirements of families are reported about staying with their children at hospital during hospitalization, taking active role in caring for their children and being informed for the health condition of the child, diagnosis and treatment tests. Therefore, family centered care is suggested for accelerating child’s recovery process with decreased child’s and families anxiety and providing the most convenient health service for expectations and needs of families in the hospital environment. Family centered care philosophy is based on recognition of the family’s central role in the child’s life and providing active participation of the family for health related decisions about their children. To effectively practice family centered care, nurses must be clear and consistent in their understanding and practices about the care of children and their families. Child Health Nurses need valid and reliable measurement tools to show their perceptions and practices regarding family centered care. In the literature, Family Centered Care Questionnaire, Family Centered Care Survey and Measure of Processes of Care for Service Providers were found to assess family centered care applications. However, the studies showing status of family centered care model in our country and studies introduce this measurement tools are very limited.

However, there is a need to determine the pattern of velocity profile when fluid flow in a circular pipe filled with layers of porous media of different porosities. A circular pipe was completely filled with layers of sands of different porosities. The flow takes place through the sands and volume flux for different layers of sand arrangement was obtained by volumetric approach. The velocity profile graphs show the velocity distribution or pattern for these arrangements. Unlike when the pipe is completely filled with water, velocity increases from the pipe centre to maximum at pipe wall when water flow from lower to higher permeable sands. However, the velocity increases from pipe wall to maximum at pipe centre when water flow from higher to lower permeable sands. This shows that the former arrangement is the most suitable arrangement for deflecting fluid by layered heterogeneous sands to different directions from normal.
