Carrier Planning and Employees' Burnout Level in Companies
Arastırmada, günümüzde küresellesme ve rekabetin etkisiyle önem kazanan kariyer kavramının getirisi olan, örgütsel kariyer planlaması ile yoğun stres sonucu olusan tükenmislik sendromu açıklanmaya ve bu kavramlar arasındaki iliski belirlenmeye çalısılmıstır. Kariyer, kisinin çalısma yasamınca üstlendiği islerin bütünü olarak tanımlanmıstır. Kariyer planlamasının ise, birey açısından kariyer hedeflerini olusturarak baslayacağı, örgüt açısından ise, ilerleyebilecek vasıftaki çalısanların seçilerek, kariyer yollarının olusturulacağı ve yönetileceği bir süreç olduğu belirtilmistir. Tükenme, bireyin kendisine büyük hedefler koyması sonucunda, hayal kırıklığına uğraması ve enerjisinin tükendiğini hissetmesi olarak açıklanmıstır. Arastırmanın turizm sektöründe uygulanmasının sebepleri arasında, yüksek dıs ticaret açıkları tasıyan ülkelerin ihtiyaç duyduğu döviz girdisini sağlaması ve yarattığı istihdam olanaklarıyla issizliğin azaltılmasına katkıda bulunması gösterilmistir. Turizm sektöründe, insan faktörü öneminin daha da belirginlesmesi nedeniyle, çalısanların tükenmislik düzeyinin, isletmelerin performansını etkileyeceği ve bu nedenle sektördeki isletmelerin rekabet açısından nitelikli isgücü istihdam etme zorunluluğu tasıyacağı düsünülmüstür. Anket formları, Aydın ilindeki dört ve bes yıldızlı olan 37 otele ulastırılmıs ancak 29 tanesinden geri dönüsüm alınabilmistir. Toplamda 190 kisiye uygulanan anketlerin değerlendirilmesinde SPSS programı kullanılarak, regresyon analizi yapılmıstır. Elde edilen bulgular sonucunda, arastırmanın hipotezi doğrulanmıs ve iki faktör arasında ters yönlü bir iliski olduğu sonucuna varılmıstır. Buna göre, kariyere verilen önem arttıkça, mesleki tükenmislik düzeyi azalmaktadır.
In this research, increasing importance of carrier concept and its result of organizational planning and burnout because of intensive stress all results from globalization and enhanced competition have been investigated. Relationships among these concepts are also explored. Carrier is defined as all tasks assigned to a person during his work life. Carrier planning is defined as to form career targets for individuals and to pick appropriate individuals for promotion and tasks from the point of organization. Burnout is defined as the individuals to define higher targets and because of disappointment, the depreciation of individual energy and the feeling of exhaustion. The reason that research is applied in tourism industry is that this sector can supply necessary foreign currency needed for a developing country and can help to reduce unemployment because of higher employment opportunities. Since human capital is more vital in tourism industry, exhaustion of workers thought to effect the performance of the companies. Because of this, companies require to hire qualified workers to complete with other organizations in the industry. Survey has been sent to 37 five or four star hotel in Aydin region, yet only 29 responses have been received and total 190 people have been participated in the survey. The analysis of the data has been performed by using SPSS statistical package program. Results proved the research hypothesis and we found that there is negative relationship between the previously mentioned two factors. We could argue that as the importance of carrier increases, the burnout levels decrease

Ultrasound-guided thyroid nodule fine-needle biopsies — comparison of sample adequacy with different sampling techniques, different needle sizes, and with/without onsite cytological analysis
Wstęp: Celem niniejszego badania było porównanie diagnostycznej wydajności próbek guzków tarczycy otrzymanych metodą biopsji aspiracyjnej lub kapilarnej, wykonanej za pomocą igieł nr 22 lub nr 27 z lub bez analizy cytologicznej przeprowadzonej na miejscu.
Materiały i metody: Czterystu pacjentów z guzkami tarczycy poddano biopsji cienkoigłowej pod kontrolą USG. Pacjentów podzielono na osiem grup, według wielkości zastosowanych igieł (nr 22 vs. nr 27), techniki biopsji (aspiracyjnej kontra kapilarnej), a także przeprowadzonej lub nie analizy cytologicznej na miejscu. Wskaźniki wydajności próbek obliczono dla każdej grupy i podgrupy oraz porównano je za pomocą testu chi-kwadrat.
Wyniki: W grupie wszystkich ocenianych guzków (n = 400), wskaźnik wydajności był znacznie wyższy w grupie badanej techniką kapilarną niż w grupie badanej metodą aspiracyjną (97% vs. 91,5%, p = 0,032). Wskaźnik wydajności był również wyższy, gdy przeprowadzono analizę cytologiczną na miejscu niż gdy jej nie przeprowadzono (97% vs. 91,5%, p = 0,032). Wśród guzków litych (n = 205), wskaźnik wydajności również osiągnął wyższą wartość w grupie badanej techniką kapilarną względem grupy badanej techniką aspiracyjną (98,9% vs. 89,7%, p = 0,008), oraz gdy przeprowadzono analizę cytologiczną na miejscu (97,9% vs. 89,6%, p = 0,014). Inaczej niż dla powyższych wyników, wskaźnik wydajności był podobny dla igieł nr 22 i nr 27 (94,2% vs. 93,1%, p = 0,733).
Wnioski: Wyniki optymalne uzyskano techniką kapilarną oraz wykonując analizę cytologiczną na miejscu. Technika kapilarna oraz analiza cytologiczna na miejscu powinny stanowić preferowane podejście w biopsji guzków tarczycy, optymalizując wskaźnik wydajności oraz samopoczucie pacjenta.

Introduction: The aim of this study was to compare the diagnostic adequacy of thyroid samples obtained by aspiration or capillary biopsy techniques, with 22 or 27 gauge needles, and with or without onsite cytological analysis (OCA).
Material and methods: Four hundred patients with thyroid nodules underwent ultrasound (US)-guided fine-needle biopsies. Patients were divided into eight groups according to needle size (22 vs. 27 gauge), biopsy technique (aspiration vs. capillary), and whether or not OCA was performed. Sample adequacy rates were calculated for each group and subgroups and compared using chi-square tests.
Results: When all nodes were evaluated (n = 400), the adequacy rate was significantly greater with the capillary than with the aspiration technique (97% vs. 91.5%, p = 0.032) and when OCA was than was not performed (97% vs. 91.5%, p = 0.032). When only solid nodules were evaluated (n = 205) the adequacy rate was also significantly greater with the capillary than with the aspiration technique (98.9% vs. 89.7%, p = 0.008) and when OCA was than was not performed (97.9% vs. 89.6%, p = 0.014). In contrast, the adequacy rate was similar for 22 and 27 gauge needles (94.2% vs. 93.1%, p = 0.733).
Conclusions: Optimal results were obtained with the capillary technique and OCA. The capillary technique and OCA should be the preferred approach in thyroid nodule biopsy, optimising adequacy rates and patient comfort. (Endokrynol Pol 2015; 66 (4): 295–300)
Postharvest Application of Thiol Compounds Affects Surface Browning and Antioxidant Activity of Fresh-Cut Potatoes
The aim of this study was to compare the effects of sodium metabisulphite and the thiol compounds, glutathione (GSH), L-cysteine (CYS), and N-acetylcysteine (NAC), on the enzymatic browning, antioxidant activities, total phenolic, and ascorbic acid content of potatoes after 1, 24, and 48 hr. Three different concentrations (0.5%, 1.0%, and 2.0%) of each thiol compound were tested. While sulphite solution inhibited polyphenol oxidase as expected, NAC and CYS also decreased its activity. CYS-treated samples exhibited the highest residual thiol content, while the amount of residual thiol in GSH-treated samples was the lowest. The 2.0% NAC and 2.0% CYS solutions were the most effective at increasing antioxidant activity and ascorbic acid content; however, the results of total phenolic content assays were complicated. In summary, solutions containing 2.0% NAC, 1.0% CYS, and 2.0% CYS prevented enzymatic browning and increased the residual thiol content, ascorbic acid, and antioxidant activities of fresh-cut potatoes significantly, but GSH did not significantly inhibit browning. Practical applications: Fresh-cut potatoes are susceptible to enzymatic browning, which significantly reduces their commercial value. In literature, there have been several methods to protect the enzymatic browning of fruits and vegetables. Among these methods, thiols are good inhibitors of enzymatic browning. So, GSH, CYS, and NAC were used in this study. The outcomes of current work may help to inhibit polyphenol oxidase activity and increase the ascorbic acid content, residual thiol content, and antioxidant activity of fresh-cut potatoes. Both CYS and NAC may be useful alternatives to sulphite anti-browning agents, which may have adverse health effects
Evaluation of Physicochemical, Nutritional and Sensory Properties of the Wet Tarhana
The wet tarhana is a fermented product that prepared with wheat flour, yogurt, tarhana herb (Echiophora sibthorpiana) and some chopped vegetables and spices. The basic difference of wet tarhana from other tarhana types is that it is prepared without a drying step. During its spontaneous fermentation process about 10 days, yogurt bacteria (Streptococcus thermophilus and Lactobacillus bulgaricus) produce several organic acids such as lactic acid and some other organic compounds. The ingredients and long fermentation process gain characteristic flavor and unique taste to the tarhana. Tarhana is similar to sourdough due to its' long spontaneous fermentation time. The aim of the study was to investigate physicochemical, nutritional and microbiological properties of wet tarhana, and to evaluate the relationships between them. For this purpose, wet tarhana samples were collected from different districts, and some physicochemical properties (pH, total acidity, dry matter, fat, and soluble ash content), antioxidant activity, phytic acid content, bioavailability, viscosity and counts of microbiota were performed. The results showed that the level of mineral digestibility was ranged from 67.22% to 88.88%, and a negative correlation was determined between mineral bioavailability and phytic acid content. The vitality of the microbiota especially lactic acid bacteria maintained during the storage period. Moreover, tarhana soups were prepared with the samples and their viscosity and sensory assessment were performed. Although the wet tarhana and soup samples had different viscosities initially, all the samples indicated pseudoplastic flow behavior. Furthermore, it was determined that the physicochemical properties of the samples affected the preference of the panelists in terms of sensorial assessment.

Kırmızı biberin (capsicum annuum l.) fonksiyonel ve mikrobiyal özellikleri üzerine modifiye atmosferde paketlemenin etkisi
06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Bu çalışmada kırmızı biberin (Capsicum annuum L.) fonksiyonel ve mikrobiyal özellikleri üzerine modifiye atmosfer paketlemenin etkisi araştırılmıştır. Ayrıca modifiye atmosfer paketlenen örneklerde etilen emicinin etkisi de bir diğer araştırma konusu olmuştur. 10oC sıcaklıkta, %95 bağıl nemde ve karanlıkta 3 hafta depolanan örneklerin haftalık analizleri yapılmıştır. Antioksidan özelliklerini incelemek için DPPH radikalini giderme aktivitesi, toplam fenolik madde içeriği, OH● yakalama aktivitesi, FRAP yöntemi, askorbik asit içeriği ve CUPRAC analizi spektrofotometrik olarak uygulanmıştır. Ayrıca örneklerin tiyol analizi HPLC cihazıyla saptanmıştır. Mikrobiyolojik analizlerde ise toplam mezofilik aerobik bakteri, maya-küf, anaerobik bakteri sayısı belirlenmiştir. 3 haftalık depolama süresi sonunda modifiye atmosfer paketlenen ve paketlenmeyen grupların üçünde de DPPH radikalini giderme aktivitesi, toplam fenolik madde, OH● yakalama aktivitesi, askorbik asit, CUPRAC ve tiyol içeriklerinde önemli derecede azalma meydana gelirken FRAP değerlerinde etilen emici bulunmayan grubta taze örneklere göre artış görülmüştür (P<0,05). Modifiye atmosfer paketlemenin etkisi incelendiğinde ise paketlenen örneklerin DPPH radikalini giderme aktivitesi, OH● yakalama aktivitesi, askorbik asit içeriği, FRAP ve CUPRAC değerleri paketlenmeyen kontrol grubuna göre yüksek bulunmuştur. GSH ve CYS değerlerinde ise tersi bir durum ortaya çıkmıştır. Toplam fenolik madde içeriğine bakıldığında paketlenen grup ile paketlenmeyen grup arasındaki fark istatistiki açıdan önemli bulunmamıştır (P<0,05). Modifiye atmosfer paketlenen gruplar arasında etilen emicinin etkisi incelendiğinde, 2. hafta sonunda etilen emici bulunan gruplarda toplam fenolik madde, FRAP ve askorbik asit değerleri etilen emici bulunmayan gruplara göre istatistiki açıdan yüksek olduğu belirlenmiştir. Ancak 3. hafta sonunda etilen emici bulunmayan grup daha yüksek DPPH radikalini giderme aktivitesi değerlerine sahip olurken toplam fenolik madde, OH● yakalama aktivitesi, FRAP ve CUPRAC değerlerinde 2 grup arasında istatistiki açıdan fark önemli bulunmamıştır (P<0,05). Üç hafta boyunca etilen emici bulunan gruplarda GSH içeriği istatistiki açıdan yüksek olurken, CYS içeriğinde etilen emici yalnızca 1. hafta sonunda etkili olmuştur. Yapılan mikrobiyolojik analizler sonucunda depolanan hiçbir örnekte toplam mezofilik aerobik bakteri, maya-küf ve anaerobik bakteriye rastlanmamıştır. Sonuç olarak bu çalışma göstermiştir ki modifiye atmosfer paketleme yapılan kırmızı biberlerin antioksidan özellikleri paketlenmeyen örneklere göre daha yüksektir. Paketlenen örnekler arasında etilen emicinin etkisi incelendiğinde ise 2. hafta sonuna kadar etilen emici kullanımının biberlerin fonksiyonel özelliklerini daha iyi koruduğu belirlenmiştir.In this study, effects of MAP on functional and microbial properties of red pepper (Capsicum annuum L.) were investigated. Moreover, effect of ethylene absorber on MAP samples was another research topic. Samples stored at 10oC with 95% relative humidity were analyzed weekly in 21 days. To investigate antioxidant properties of samples, DPPH scavenging activity, total phenolic contents, ,OH● scavenging activity, FRAP, ascorbic acid content and CUPRAC analyses were applied spectrophotometrically. In addition, thiol contents were determined by HPLC. Total mesophilic aerobic bacteria, yeast-mold, anaerobic bacteria numbers were detected with microbiological analyses. After 3 weeks storage time, while DPPH scavenging activity, total phenolic compounds, OH● scavenging activity, ascorbic acid and CUPRAC values were decreased in all groups, FRAP values in samples not include ethylene absorbers were increased according to fresh samples (P<0,05). DPPH scavenging activity, OH● scavenging activity, FRAP, ascorbic acid content and CUPRAC values were found higher in MAP samples than the control group. However, thiol contens in MAP group were lower than controls. According to total phenolic compounds, the difference between MAP and the control group was not significant (P<0,05). As a result of microbiological analyses, total mesophilic aerobic bacteria, yeast-mold and anaerobic bacteria was not found any of the samples. When the effect of ethylene absorber was examined on MAP samples after 2 weeks, it was seen that the groups with ethylene absorber had higher total phenolic compounds, FRAP, GSH and ascorbic acid values. On the other hand, while the groups without ethylene absorber had higher DPPH scavenging activity and CYS content, there was no significant difference according to OH● scavenging activity and CUPRAC values between these two groups in statistical analysis. As a result, this study indicates that the modify atmosphere packaging of red peppers have higher antioxidant property than the control group. In addition, using ethylene absorber protects the functional properties of red pepppers better than other group at the end of 2 weeks

Testing antidepressant compounds in a neuropsychological model of drug action
Although much research effort has been put into the development of new antidepressant drugs, the process of developing a drug often fails at the stage of large randomized controlled trials (RCTs) in which an initially promising compound appears to lack efficacy after all. Several experimental medicine models have been proposed as preclinical tools in order to predict drug efficacy before the stage large RCTs. Among the various experimental medicine models, the cognitive neuropsychological model has been proposed as a tool to predict the efficacy of antidepressant drug even before the stage of large scale and expensive RCTs. We applied the cognitive neuropsychological model of drug action to test antidepressant effects of a novel compound (ARA290) and a well-known compound (L-tryptophan). We further investigated the model by tapping into HPA-axis reactivity and social decision making as additional outcomes, and investigated their interaction with a genetic marker.VICI grant (NWO) - Prof. dr.
