In this study a
semi-quantitative analysis was done in order to determine the views of workers
who work in direct medical services related to health and safety hazards and
risks in the workplace by receiving the opinions of those workers. Thus,
appropriate suggestions with determined hazards and risks were evaluated. This
research was performed from January to March 2015 in Ankara with 22
participants who were choosen by voluntary basis from the direct medical
service units in a public hospital affiliated to Turkish Ministry of Health
that has 227 health worker and 97 beds. Opinions were received by asking the
questions that are in a semi structured interview form, which was developed by
the author as a data collection tool, individually and  face to face. . Descriptive analysis
technique was used to analyze the data. The answers were evaluated in two ways:
separately for each and totally. It was determined that the participants were
aware of several hazards and risks in their units. Also in all the units
violence and infection were described as risks that has the most
heightened awareness and it
was determined that most of the participants were suffered from musculoskeletal
diseases.

Kablosuz kontrol amacıyla geliştirilmiş bir proses kontrol simülatöründe sistem dinamiğinin teorik ve deneysel incelenmesi

Sistem tanımlama, proses kontrol
çalışmalarının başarısını etkileyen oldukça önemli bir işlemdir. Sistem
tanımlama için kablosuz proses kontrol simülatöründe deneysel ve MATLAB
kullanımıyla teorik çalışmalar yapılmıştır. Kablosuz sıvı seviye deneylerinde
öncelikle yatışkın hal deneyleri gerçekleştirilmiştir. Sistem dinamiğini
incelemek amacıyla sıvı seviye vana açıklığına basamak, PRBS ve kare dalga
etkiler verilerek sıvı seviyesinin zamanla değişimi gözlenmiştir. Böylelikle
açık hat dinamik deneyler gerçekleştirilerek sistemin özellikleri
belirlenmiştir. Proses kontrol simulatörünün sıvı seviyesiyle, sıvı seviye
kontrol vanası açıklığı arasındaki ilişkiyi verecek modelin bulunması için,
farklı giriş sinyalleri (basamak etki, PRBS, kar dalga) uygulanarak sistem
tanımlama yapılmıştır. Dinamik hal deneylerinde başlangıçta %10 vana
açıklığında 100s çalışılarak sistemin yatışkın hale gelmesi beklenmiş, daha
sonra  sıvı seviye kontrol vanasına
pozitif ve negatif etkiler verilerek deneyler gerçekleştirilmiştir. Sistem
tanımlama deneylerinde sistemin birinci mertebeden ölü zamanlı modele sahip
olduğu varsayılmıştır. Sistem tanımlama için sıvı seviye vanasına verilen
etkiler (%10-%65) sonucu elde edilen çıkış değişkeni verileri kullanılmıştır.
Bu amaçla giriş ve çıkış değişkenlerinin değerleri MATLAB ‘Sistem tanımlama
araç kutusu’na işlenerek ARIMAX model katsayıları (a1, a2, b0, b1, b2,c1 ve c2)
belirlenmiştir.
