Observation of melting conditions in selective laser melting of metals (SLM)

Process observation in 3D printing of metals currently is one of the central challenges. Many companies strive to employ this additive manufacturing process in their production chains in order to gain competitive advantages through added flexibility in product design and embedded features. The new degrees of freedom are accompanied with the challenge to manufacture every detail of the product to the predefined specifications. Products with filigree internal structures for example require a perfect build to deliver the performance that was designed into these structures. Melting conditions determine properties such as grain structure and density of the finished part before it is sent to post processing steps. Monitoring of such melting conditions is still a challenge where the use of photodiodes, pyrometry and camera systems contribute to an overall picture that might identify errors or deviations during the build process. Additional considerations must be made to decide if these sensors are applied coaxially or from a lateral perspective. Furthermore, setting parameters of focal plane array (FPA) sensors are discussed and events that are seen in the machine vision image are compared against the pyrometry data. The resume of the experiments suggests the application of multiple sensors to the selective laser melting process (SLM) as they jointly contribute to an identification of events. These events need to be understood in order to establish cause effect relationships in the future

The examination of injuries which are based on the declarations of nurses working in a university hospital

Bu tanımlayıcı çalışmada, bir üniversite hastanesinde çalışan hemşirelerin bildirimlerine dayalı geçirdikleri iş kazaları incelenmiştir. Method: Araştırmada örnekleme gidilmeden, hastanede çalışan tüm hemşirelere (527) ulaşılmaya çalışılmıştır. Ancak evrenin % 71.4'ü çalışmaya katılmıştır (n=405). Toplam 19 sorudan oluşan anket formunda sosyodemografik ve iş öyküsü özellikleri ile son bir ay içinde kılpayı atlatılan ve son altı ay içinde geçirilen iş kazaları arasındaki farklar incelenmiştir. Bulgular: Hemşirelerin yaş ortalaması 32.3±0.3'tür. Hemşirelerin % 60'ı evli, % 29.1'i mesleğini dört yıldan daha az bir süredir yapmakta ve % 33.1'i de cerrahi birimlerde çalıştırılmaktadır. Hemşireler en fazla ilaç gibi kimyasal maddelerin sağlıklarını olumsuz etkilediğini düşünmektedir. Hemşirelerin son bir ayda kılpayı atlattığı iş kazası oranı % 46.4, son altı ay içinde iş kazası geçirme oranı da % 60'tır. Sonuçlar: En fazla geçirilen iş kazası kesici-delici alet yaralanmasıdır (% 42). Dört yıldan az bir süredir çalışanlarda ve cerrahi birimlerde istihdam edilen hemşirelerde iş kazası geçirme oranı daha yüksek bulunmuştur. Hemşirelerin sözel şiddete uğrama oranı fiziksel şiddete uğrama oranından daha yüksektir. Kayma-düşme yaralanmalarının en büyük nedeni kaygan zemin olarak bulunmuştur. In this descriptive study, injuries which are based on the declarations of nurses working in a university hospital are examined. Method: In the research we tried to reach all nurses (527) working in the hospital without using sampling method. However, %71.4 percent (n=405) of the nurses have attended the study. In the questionnaire form, which is consisting of 19 questions, sociodemographic and work story properties, near accidents happened in the last month and injuries happened in last six months are examined. Findings: Age average of the nurses is found 32.3±0.3. %60 of the nurses are married, %29.1 are working more than four years and %33.1 are working in the surgery units. Nurses are thinking that chemical materials like drugs have negative effects on their health. The rate of the near accidents experienced by nurses in last month is % 46.4, the rate of injuries happened in last six months is found %60. Results: Most of the injuries are based on blunt-penetring instruments with the average of %42. Work accident rate of employees that has been working less than four years and nurses in surgical unit was found higher. The rate of verbal violence to nurses is found higher then the physical violence. Slip-fall injuries were found to be the biggest cause of slippery floors. Keywords: Nurses, work health, work injuries, near accident
