The effect of organizational alienation phenomenon on job satisfaction: A research in the province of Nigde

Endüstriyel devrim sayesinde makine kullanımındaki artış küresel rekabet koşullarını yükseltmiş ve işletmeler bu hızlı değişime ayak uydurabilmek için teknolojilerini geliştirme gereksinimi duymuşlardır. Ancak bu rekabet koşullarında yalnızca teknolojideki gelişimlerin yeterli olmayacağı ve en değerli kaynak olan “insan” ın önemi çok geç olmadan anlaşılmıştır. Bu çalışmanın amacı, rekabet koşullarında fark yaratarak işletmeleri başarıya taşıyabilecek “insan” kaynağının karşı karşıya olduğu örgütsel yabancılaşma duygusunun iş tatmini üzerinde ne derece etkili olduğunu ortaya koymaktır. Çalışmada öncelikle yabancılaşma ve iş tatmini kavramları açıklanmış daha sonra ise yabancılaşmanın iş tatmini üzerindeki etkisini sınamak amacıyla Niğde ili sanayisinde otomotiv, tekstil ve maden özel sektörlerinde görev yapan çalışanları kapsayan, ankete dayalı bir araştırmaya yer verilmiştir.Thanks to the Industrial Revolution, the increase in machine utilization raised the global conditions of competition and to be able to keep up with this rapid development, institutions felt the need for improving their technologies. However, the fact that technological developments alone would not be enough in these conditions of competition and the importance of “human” which is the most valuable resource was understood soon. The aim of this study is to point out how the feeling of organizational alienation that “human” resource, which can bring institutions success by making difference in conditions of competition, is facing affects job satisfaction. In the study first the terms of job satisfaction and alienation were defined and explained and then with the aim of examining the effects of organizational alienation on job satisfaction, a research which includes the employee working in automotive, textile and mining private industries in the province of Nigde and which is based on a questionnaire was included

The use of the technology of the previous period in each period and the new breakthroughs for the next period pave the way for companies to grow. The biggest companies / structures of the world are explaining the reason of their growth by learning the information that people use. The best example of this is the search engines in browsers on each individual's computer. In these scanners, it is determined that people's interests, wishes, attitudes and thoughts are determined and these data are kept constantly. The importance of the information obtained with these data and the fact that it is known in advance that this information will be transformed into the structures, is one of the top where the companies / structures using technology are important. Here, it will become even more important to determine what the information will turn into in the future, how the network is between people and the relationship between the data to determine the needs over time. With the data identified, people will be able to estimate technology and take measures where necessary, and they will have the opportunity to update themselves according to future changes. In the thesis, the flow of data used in the course content was checked in the laboratory used by the student between the dates of 01.03.2018 and 10.05.2018 (9 weeks). The computers used by the students were analyzed during the same day of the week and at the same time. As a result of the analysis, the websites that students went to were detected and certain results were reached. The data traffic over the network was monitored and the frequency at which web sites were visited was determined by using the association rules. Because it is the most suitable data for the association rules, it has been examined with Apriori algorithm, compared with Eclat algorithm and analyzed with Anaconda compiler and visualized with R studio. The effect of variables such as age, grade and gender on the results were also included in the analysis. The relationships of the websites visited with this data set were discussed and the monitored network was analyzed and the results of the method used were specified

Procjena proizvodnosti i gubitaka zbog reprodukcijskih poremećaja u mliječnih goveda zaraženih goveđim herpesvirusom 1.

Infectious bovine rhinotracheitis caused by bovine herpesvirus 1 (BoHV 1), which negatively affects the production performance of infected cattle herds, results in considerable economic losses in dairy farms. The present study aimed to estimate farm-level production and reproductive performance losses in seropositive (SP) dairy cattle infected with BoHV-1. A total of 266 non-vaccinated cows were selected from 31 herds located in different parts of Hatay, Turkey. Data collected from SP and seronegative (SN) cows were compared with each other. Compared to the SN cows, 10% and 9% decreases were found regarding milk production (P<.01) and live weight (P<.01) in SP cows, respectively. Reproductive and mixed clinical problems in infected cows lead to the highest losses in respect of milk production and live weight, respectively. The financial loss due to the infection was estimated to be $US331 if abortion does not occur, and$US509 if abortion occurs as a result of the infection. Considering the likelihood of abortion, the average cost of infection was estimated to be $US379 per infected cow.Zarazni rinotraheitis uzrokovan goveđim herpesvirusom 1 negativno utječe na proizvodne sposobnosti zaraženog stada i dovodi do znatnih gospodarskih šteta. Istraživanje je provedeno radi procjene proizvodnje i gubitaka zbog reprodukcijskih poremećaja mliječnih goveda serološki pozitivnih na goveđi herpesvirus 1. Za istraživanje je bilo odabrano ukupno 266 necijepljenih krava iz 31 stada iz različitih dijelova područja Hatay u Turskoj. Međusobno su uspoređeni rezultati od serološki pozitivnih i serološki negativnih krava. U usporedbi sa serološki negativnim kravama proizvodnja mlijeka u serološki pozitivnih bila je smanjena za 10$ ako se nije javljao pobačaj, a 509 US $kad se javljao pobačaj kao rezultat infekcije. Razmatrajući vjerojatnost pojave pobačaja, prosječni gubitak od infekcije procijenjen je na 379 US$ po zaraženoj kravi

Three-axis gap clearance I-PD controller design based on coefficient diagram method for 4-pole hybrid electromagnet

4-pole hybrid electromagnetic systems have a potential usage in many industrial areas, such as clean room design, transportation, semi-conductor manufacturing due to providing mechanical contact-free operation with considerably low energy consumption. However, the main problem of magnetic levitation process: it has highly nonlinear nature and even if it can be linearized, it has unstable pole(s), which makes the system vulnerable in terms of stability. In this paper, to overcome the instability issue and track the desired references for each degree of freedom, a modified PID controller (so called I-PD) design technique based on coefficient diagram method (CDM) has been proposed. CDM is an algebraic design applied to polynomial structure of the system on the parameter space, where a specific diagram is used to present and interpret the essential data. It is quite simple to apply with a visual support, requires basic mathematical computations for field engineers, and offers a good equilibrium in terms of simplicity, stability, minimum overshoot and robustness, which are crucial specifications for maglev applications. The effectiveness and feasibility of CDM-based I-PD controller have been compared with CDMbased classical PID controller over an experimental set-up

Dynamic Weighing Method with Time-variant IIR Low-pass Filter

Sanayide üretimden sevkiyat aşamasına kadar birçok alanda kullanılan otomatik ağırlık kontrol sistemi, üç adet konveyör bant, en az iki adet fotosel, yük hücresi, işlemci, kullanıcı için kontrol ekranı ve reddedici/yönlendirici kollarından oluşmaktadır. Ağırlık ölçerken, yük hücresi tarafından alınan ölçüm sinyalinin filtrelenmesi aşamasında literatürde kaskat yapıda zamanla değişen alçak geçiren filtrenin önemli bir yeri olduğu gözlemlenmiş ancak sonuca ulaşma konusunda oldukça fazla filtre adedinin mevcut olduğu gözlemlenmiştir. Sonuçlara ulaşma aşamasının hızlandırılması amacıyla bu çalışmada zamanla değişen alçak geçiren filtre ile farklı bir yaklaşım denenmiştir. Sonuca daha hızlı ulaşabilmek için kaskat bağlı alçak geçiren filtre adedi önem arz etmektedir. Filtre adım adım uygulanarak oluşan salınımlardan ürünün ağırlığına minimum filtre adedi ile ulaşmak hedeflenmiştir. Matlab'ta yapılan deneyler sonucunda çok yüksek hızlarda bu işlemle yönetmelikte belirtilen hata limitleri içerisinde sonuçların elde edilemediği görülmüş olup hata limitleri içerisinde elde edilen maksimum hız belirtilmiştir. Sonuç olarak filtre adedi azaltılıp, sönümleme hızlandırılarak oluşan salınımlardan ağırlık verisine yönetmelikte verilen hata sınırları içerisinde ulaşılmıştır.The automatic weight control system, in other words checkweigher is used in many areas from production to shipment in the industry, consists of three conveyor belts, at least two photocells, load cell, processor, control screen for the user and rejector/router arms. It has been observed in the literature that the time-varying low-pass filter in the cascade structure plays an important role in the filtering of the measurement signal received by the load cell while reaching the product mass, but it has been observed that quite a lot of filters are used to reach the result. In this study, a different approach was tried with a time-variant low-pass filter in order to accelerate of reaching the results. The number of cascade form low-pass filter used in filtering is important to get the accurate weight. By applying the filter step by step, it is aimed to reach the mass of the products from the oscillations with minimum number of filters. As a result of the experiments carried out in MATLAB, it was observed that the results could not be obtained within the error limits specified in the regulation with this process at very high speeds. The maximum speed obtained within the error limits was specified. As a result, by reducing the number of filters and increasing the damping, the mass of product from the oscillations were reached faster within the error limits given in the regulation

Mobility Strategy of Multi-Limbed Climbing Robots for Asteroid Exploration

Mobility on asteroids by multi-limbed climbing robots is expected to achieve our exploration goals in such challenging environments. We propose a mobility strategy to improve the locomotion safety of climbing robots in such harsh environments that picture extremely low gravity and highly uneven terrain. Our method plans the gait by decoupling the base and limbs' movements and adjusting the main body pose to avoid ground collisions. The proposed approach includes a motion planning that reduces the reactions generated by the robot's movement by optimizing the swinging trajectory and distributing the momentum. Lower motion reactions decrease the pulling forces on the grippers, avoiding the slippage and flotation of the robot. Dynamic simulations and experiments demonstrate that the proposed method could improve the robot's mobility on the surface of asteroids.Comment: Submitted version of paper accepted for presentation at the CLAWAR 2023 (26th International Conference on Climbing and Walking Robots and the Support Technologies for Mobile Machines

Ozone therapy as a novel complementary therapeutic approach in refractory idiopathic granulomatous mastitis

Background: Autoimmunity may play a major role in the pathogenesis of idiopathic granulomatous mastitis (IGM). The therapeutic potential of ozone therapy has recently been shown in rheumatological diseases, and this study aimed to assess the clinical efficacy of ozone therapy (OT) in refractory IGM. Methods: Patients with biopsy-verified IGM and incomplete response after steroid therapy (n = 47) between 2018 and 2021 were enrolled. Of these, 23 cases in cohort A had standard treatment with further steroid therapy (ST), and 24 were treated with systemic OT via autohemotherapy (AHT) in addition to steroid therapy (cohort B). Results: The median age was 33 years (range, 24–45). Patients in cohort B had a higher complete response rate after completion of a four-month ozone therapy than those in the ST-group (OT-group, 37.5% vs. ST-group, 0%; p = 0.002). At a median follow-up of 12 months (range, 12–35), the patients treated with OT had a lower one-year recurrence in the affected breast than cases in cohort A treated with ST (OT-group, 21% vs. ST-group, 70%; p = 0.001). No significant side effects were observed in patients in cohort B related to AHT. Furthermore, OT significantly decreased the total steroid treatment duration (median week of steroid use; 26 weeks in cohort A vs. 12 weeks in cohort B; p = 0.001). Conclusion: Systemic OT increases the complete response rate and decreases the duration of steroid treatment in patients with refractory IGM. Therefore, ozone therapy is an effective, well-tolerated, and safe novel complementary therapeutic modality.Istanbul Breast Societ

Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study

PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision

Türkiye’de sığır üreticilerinin örgütsel sorumluluk ve memnuniyet düzeylerinin incelenmesi

Bu çalışmanın amaçları, farklı örgütlere ve Türkiye’nin farklı coğrafik bölgelerine göre sığır üreticilerinin memnuniyet ve sorumluluk düzeylerinin belirlenmesi ve sosyoekonomik değişkenler ile ifade edilen düzeyler arasındaki ilişkilerin analiz edilmesidir. Çalışma, Türkiye’nin 6 farklı bölgesinde tesadüfi olarak örneklenmiş toplam 197 üreticiyle 2013-2014 yılları arasında yürütülmüştür. Türkiye geneli için sorumluluk ve memnuniyet düzeylerinin medyan değerleri sırasıyla 2 (0-6) ve 42% (20-100) olarak bulunmuştur. Doğu–Güneydoğu Bölgesi ile Süt Üreticileri Birliği için sorumluluk ve memnuniyet düzeyleri diğer gruplardan anlamlı biçimde daha düşük bulunmuştur (?.01). Üreticilerin yalnızca %11’i kendi örgütleriyle ilgili yasa ve yönetmelikleri bilmektedir. En düşük memnuniyet skorlarını “ziyaret sıklığı” ve “toplantı düzenleme” bileşenleri almıştır. Toplam 11 sosyoekonomik değişkenin sırasıyla 7 ve 4 tanesi sorumluluk ve memnuniyet düzeyleriyle anlamlı pozitif bir ilişki içindedir. Sığır üreticilerinin algı ve davranışlarını değiştirmek için hayvancılık alanındaki örgütler ve kamu tarafından çiftlik ziyaretleri ve periyodik toplantılar düzenlenmelidir. Türkiye’nin Doğu ve Güneydoğu bölgelerinde yaşayan ve düşük sosyoekonomik statüdeki üreticilere eğitim programlarında öncelik verilmelidir.The aims of this study were to determine organizational responsibility and satisfaction levels of cattle producers according to different organizations and geographical regions of the Turkey, and to analyze the relationship between socioeconomic variables and above mentioned levels. The study was conducted with a total of 197 randomly sampled producers living in six different regions of the Turkey, between the years of 2013 and 2014. For overall Turkey, median responsibility and satisfaction values were found to be 2 (0–6) and 42% (20-100), respectively. Responsibility and satisfaction levels of the East–Southeastern region and the Milk Producers Association were significantly lower than other groups (&amp;#706;.01). Only eleven percent of the producers know important laws and regulations related to their own organizations. “Visiting frequency” and “meeting arrangements” components were given the lowest scores for satisfaction. Seven and four socioeconomic variables out of 11 were significantly positively correlated with the responsibility and satisfaction levels, respectively. In order to change the cattle producers’ perception and attitudes farm visits and regular periodic meetings should be arranged by both livestock organizations and government. Those cattle producers, living in the East and Southeastern regions of Turkey and having low socioeconomic status, should be given priority in training programs
