Ozturk, Samet; Bowler, Alexander; Rady, Ahmed; Watson, Nicholas J.
In food production environments, the wrong powder material is occasionally loaded onto a production line which impacts food safety, product quality, and production economics. The aim of this study was to assess the potential of using Near Infrared (NIR) spectroscopy combined with Machine Learning to classify food powders under motion conditions. Two NIR sensors with different wavelength ranges were compared and the ML models were tasked with classifying between 25 food powder materials. Eleven different spectra pre-processing methods, three feature selection methods, and five algorithms were investigated to find the optimal ML pipeline. It was found that pre-processing the spectra using autoencoders followed by using support vector machines with the all spectral wavelengths from both sensors was most accurate. The results were improved further using under-sampling and boosting. Overall, this method achieved 99.52, 97.12, 94.08, and 91.68% accuracy for the static, 0.017, 0.036 and 0.068 m s-1 sample speeds. The models were also validated using an independent test sets.

Kocan, Sema; Aktug, Cemile; Gursoy, Ayla
Background: Since alopecia may be the first physical evidence and sign of cancer diagnosis and treatment, it may have a more serious and challenging effect on a woman than the loss of breast tissue. Objective: The purpose of this study was to summarize the current qualitative research which explores the body image perceptions of breast cancer patients with chemotherapy-induced alopecia. Material and methods: We searched three electronic databases and reviewed studies from December 2011 to December 2021 for qualitative results analysing the experiences of women with breast cancer and chemotherapy-induced alopecia. The Joanna Briggs Institute critical (JBI) appraisal tool was used to assess the quality of the targeted studies. The Meta-synthesis process developed by Sandelowski and Barroso was used to collect and analyse the data. Results: We discovered two main and five sub-themes from the meta-synthesis findings of 11 qualitative studies involving 225 women. The main themes were “I am not comfortable in this body” and “Who am I?”. The first main theme revealed patients’ intense reactions to their hair loss: “I'm in emotional chaos”, “I am looking for a place to hide” and “I knew it and now I’m experiencing it”.The second main theme of “Who am I?” contained two sub-themes: “What did my hair take from my femininity when it was gone?” and “Will I lose my partner after my hair?”. Conclusion: Meta-synthesis provided an up-to-date and integrated interpretation of scientific results about the experiences of women with breast cancer, alopecia, and their body image perceptions. This interpretation will facilitate a more comprehensive understanding of the alopecia-body image relationship. Thus, the aim of the meta-synthesis results is that these will contribute to nurses’ understanding of how alopecia, although a temporary symptom, affects women's perceptions of body image.

Seyitoğlu, Faruk; Atsız, Ozan; Taş, Sedat; Kaya, Fazıl
This study investigates the perspectives of undergraduate tourism and hospitality students on working with robots and the influence of the widespread use of robots on future careers. Accordingly, interviews were conducted with thirty students. The findings include two main categories: working with robots in the tourism and hospitality industry (advantages of working with robots, disadvantages of working with robots, and willingness to work with or implement robots) and future career impacts of the widespread use of robots (threatening human employment, reducing the motivation toward working in the industry, unfair competition between humans and robots, negative psychological impact/feeling of being less skilled than robots, and giving up/changing the industry). This research contributes to the literature by revealing the dimensions of working with robots and the future career impacts of the widespread use of robots. A model of future career impacts of the widespread use of robots was also proposed.

Yilanci, Veli; Adali, Zafer; Çelik, Orkun; Bari, Bilgin
Ecological balance is an indicator of environmental degradation, which is computed as the difference between biocapacity and ecological footprint. In this study, we examine whether the effect of shocks on the ecological balance is permanent or temporary in the EU-15 countries, considering the period from 1961 to 2018. The application of unit root tests, with and without a Fourier function, indicates that the effects of shocks are temporary in only four countries. To reveal the persistence of shocks at different frequencies, that is, the short-, medium-, and long-run, we decomposed the ecological balance series by using the Discrete Wavelet Transform method. The unit root test results show that the effects of shocks are temporary in all countries in the short-run. However, the results also show that the shocks are temporary in nine countries in the medium-run and ten countries in the long-run. Thus, the implemented policies to balance ecology are not effective in the short-run but are effective in only six countries in the medium-term and in only five countries in the long-term. These findings demonstrate the importance of considering different frequencies when testing the effectiveness of empirically implemented policies. Regarding policy implications, this study suggests focusing on medium- and long-term environmental policies rather than short-term ones.

Muhajir; Nisa, Ihda Shofiyatun; Munawar, Akhmad; Karimullah, Suud Sarim
The number of controversies and debates about integrating Islamic law into the national legal system in Indonesia has led to many counter-productive perceptions, so progressive thinking is needed all parties can accept that. Therefore, this study examines the thoughts of Agus Moh Najib, a Muslim scholar, on integrating Islamic law into the national legal system to create a fair legal system by the demands of society and the state. Methodologically, this research uses a philosophical approach with library research and is also descriptive-analytical qualitative research. The results of this study state that Islamic Law and Indonesian law have several interrelationships and interconnections perspectives on Agus Moh Najib's. He provides recommendations that to maximise the interconnectivity of Islamic law to national law, the first step that needs to be taken is to redesign, reformulate and renovate the ushul fiqh building, which is the basis for the formation of Islamic law without having to tear it down by reviewing existing concepts and theories so that the role of ushul fiqh can be more optimal in developing Islamic legal science that contributes to the formation of laws and regulations in Indonesia. Then harmonisation is carried out between Islamic law and various legal sciences developed in Indonesia regarding subject matter and language. In other words, it is necessary to strive for the formation of the Islamic law that is in harmony with legal science in general based on the ideal moral norms of the core teachings of Islam and also considers the culture and empirical realities that exist in plural Indonesian society.

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains-losses domain and high-low probability. Pay dissatisfaction (in the losses domain) incites dishonesty in the name of justice at the individual level. The Corruption Perceptions Index, CPI, signals a high-low probability of getting caught for dishonesty at the country level. We theorize that decision-makers adopt avaricious love-of-money aspiration as a lens and frame dishonesty in the gains-losses domain (pay satisfaction-dissatisfaction, Level 1) and high-low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction mitigates dishonesty across nations consistently. Based on 6500 managers in 32 countries, our cross-level three-dimensional visualization offers the following discoveries. Under high aspiration conditions, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations, supporting the certainty effect. However, pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities, sustaining the possibility effect-maximizing expected utility. Under low aspiration conditions, high pay satisfaction consistently leads to low dishonesty, demonstrating risk aversion-achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations. We enhance the S-shaped Curve to three 3-D corruption surfaces across three levels of the global economic pyramid, providing novel insights into behavioral economics, business ethics, the environment, and responsibility.

Objective: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-2) prevents the development of serious diseases has been shown in many studies. However, the effect of vaccination on outcomes in COVID-19 patients requiring intensive care is not clear.Methods: This is a retrospective multicenter study conducted in 17 intensive care unit (ICU) in Turkey between January 1, 2021, and December 31, 2021. Patients aged 18 years and older who were diagnosed with COVID-19 and followed in ICU were included in the study. Patients who have never been vaccinated and patients who have been vaccinated with a single dose were considered unvaccinated. Logistic regression models were fit for the two outcomes (28-day mortality and in-hospital mortality).Results: A total of 2968 patients were included final analysis. The most of patients followed in the ICU during the study period were unvaccinated (58.5%). Vaccinated patients were older, had higher Charlson comorbidity index (CCI), and had higher APACHE-2 scores than unvaccinated patients. Risk for 28-day mortality and in-hospital mortality was similar in across the year both vaccinated and unvaccinated patients. However, risk for in-hospital mortality and 28-day mortality was higher in the unvaccinated patients in quarter 4 adjusted for gender and CCI (OR: 1.45, 95% CI: 1.06-1.99 and OR: 1.42, 95% CI: 1.03-1.96, respectively) compared to the vaccinated group.Conclusion: Despite effective vaccination, fully vaccinated patients may be admitted to ICU because of disease severity. Unvaccinated patients were younger and had fewer comorbid conditions. Unvaccinated patients have an increased risk of 28-day mortality when adjusted for gender and CCI.

Zabci, Cengiz; Sançar, Taylan; Tikhomirov, Dmitry; Ivy-ochs, Susan; Vockenhuber, Christof; Friedrich, Anke M.; Yazici, Muge; Akçar, Naki
The active tectonics of Anatolia is mostly characterized by its westward motion with respect to Eurasia between the Hellenic subduction in the west and Arabia-Eurasia continental collision in the east. Although most of the deformation is suggested to be confined along Anatolias boundary elements, viz. the North and East Anatolian shear zones, recent studies indicate a higher magnitude of internal strain accumulation, especially along the parallel/subparallel strike-slip faults of its central province. We present the first morphochronology-based slip rate estimate for one of these strike-slip structures, the Ovacik Fault, by using cosmogenic 36Cl dating of offset fluvial deposits. At the Kcseler Site (39.3643 degrees N, 39.1688 degrees E), two faulted risers, bounding the alluvial fan with its subplanar surface (NF1/NF1') and the inset terrace tread (NF1/T2), are offset 19-24 and 15-22 m, respectively. The scattered surface ages and variability of 36Cl concentrations in depth profiles suggest strong evidence for inheritance in alluvial fan and terrace deposits; thus, we used modelled depth-profile ages for both surfaces. The modelled ages 8-10 ka for NF1 and 6-8 ka for T2 yield slip-rate estimates 2.4 +0.5/-0.4 mm/a and 2.8 +0.7/-0.7 mm/a, respectively, for the upper-tread reconstruction of the NF1/NF1'and the lower-tread reconstruction of the NF1/T2. Our results together with previous slip-rate estimates for other structures show a significant internal deformation for Anatolia, especially along its subparallel strike-slip faults. These secondary faults slice Anatolia into several pieces giving rise to the formation of the Malatya-Erzincan, Cappadocian, and Central Anatolian slices, where the geometry is strongly controlled by the distribution of the Tethyan accretionary complexes.

BackgroudTwelve taxa of herbaceous Paeonia species were recorded in Turkiye. All definitions were performed morphologically and/or anatomically and there is no study based on DNA barcode sequences. Three barcode regions were sequenced to determine the phylogenetic relationships of Turkish Paeonia taxa. The chemical comparison of roots was also investigated.Methods and resultsThe taxons were collected between May and June 2021 from nine cities. Leaf materials were used for DNA isolation and ITS, matK and rbcL regions were amplified and sequenced. There was no difference among taxa in terms of rbcL sequences. But the ITS and matK regions distinguished 12 taxa and structured them in two groups. ITS region distinguished P. peregrina, P. arietina, and P. tenuifolia from other taxa, while matK region distinguished P. arietina and P. witmanniana from other taxa. Both barcode sequences actually showed that the registration of P. mascula subsp. arasicola was actually 100% similar to P. arietina. ITS was the most polymorphic region (n = 54) followed by matK (n = 9). These sequences could successfully discriminate Paoenia species from each other and diploid P. tenuifolia. The methanolic root (100 gr) extracts were examined for total phenolic and flavonoid content, and antioxidant activities. Significant variation was found for polyphenolic content, and antioxidant properties (TPC from 204.23 to 2343.89 mg, TFC from 7.73 to 66.16 mg, and FRAP from 523.81 to 4338.62 mg). SC50 values of ABTS and DPPH were ranged from 115.08 to 1115.52 mu g/ml and 73.83 to 963.59 mu g/ml, respectively.ConclusionIt was concluded that 11 of 12 taxa had differences in terms of ITS and matK sequences and these region must be used for the correct identification of Turkish Paeonia.

Turkey's Early Paleozoic tectonic evolution has received much attention in recent years. Early Paleozoic intrusive rocks are mainly distributed across Europe, Turkey (Istanbul-Zonguldak Zone, Strandja Zone, and Tauride Block), and Iran. However, the Early Paleozoic rocks have not yet been identified in north Turkey's Sakarya Zone, and thus the Early Paleozoic paleogeography of the Sakarya Zone remains enigmatic. Here, we provide new field observations, petrography, geochemistry, and geochronology of the western Sakarya Zone to identify the nature, origin, and tectonic setting of the Ordovician magmatic rocks cropping out in the So center dot gut area (Bilecik, northwest Turkey). Our Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Pb analyses on zircons suggest that the So center dot gut metagranites were emplaced at-484-461 Ma (except two zircons with ages of 490 and 494 Ma). There are abundant inherited zircon cores in the So center dot gut metagranites, with ages of >500 Ma to-2.2 Ga. The inherited Cadomian cores give concordant ages of 588 and 572 Ma. The So center dot gut metagranites are felsic and have high SiO2 (72-76 wt%) and K2O (4.1-5.3 wt%) contents, with high K2O/Na2O ratios (1.2-1.9), and low Mg# (17-35) values. The samples are Ca-poor (CaO = 0.52-0.68 wt%) and show peraluminous [A/CNK = molar Al2O3/(K2O + CaO + Na2O) = 1.15-1.28] and high-K calc-alkaline geochemical characters, with high modal content of muscovite (-10%), consistent with S-type compositions. The samples have low REE concentrations, with negative Eu anomalies. Ordovician zircon rims show epsilon Hf(t) values of +3.6 to-35.4, whereas inherited zircon cores have epsilon Hf(t) values of +33.9 to-26.1. Our data, in conjunction with previous studies, suggest that the So center dot gut metagranites were generated by fluid-absent muscovite-dehydration melting of metasediments accumulated in a back-arc setting. This back-arc basin was characterized by a denuded continental crust with abundant pelite-dominated sediments and minor input of juvenile mafic melts. Our results, combined with previously published data and paleogeographic reconstructions, allow us to conclude that the Ordovician S-type granites were formed by progressive back-arc extension and crustal thinning prompted by the rollback of the southward subducting oceanic-lithosphere slab. This led to the opening of the Rheic Ocean on the northern side of Gondwana in response to the final closure and termination of the Tornquist Ocean as a branch of the Iapetus Ocean. We argue that the Ordovician S-type granites from the northern side of Gondwana could signal significant crustal reworking away from any clear continental collision zone.

Progranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0-90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100-150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process.

-In this study, we aimed to determine the effect of Moringa oleifera essential oil (MOEO) supplementation to rations of Japanese quail (Coturnix coturnix japonica) grown under heat stress (HS) on some adipokine (visfatin, adiponectin, and chemerin), intestinal (citrulline), 3,5,3 '-triiodothyronine (T3), thyroxine (T4), and thyroid-stimulation hormone (TSH) levels in the serum. For this purpose, 320 day-old male quail chicks were used. The study was conducted over 42 days, including a 7-d adaptation period and a 35-d experimental period. Eight trial groups were established, each including 10 quail: CT (control temperature, 25 celcius), MOEO 200, MOEO 400, MOEO 600, HSC (HS control), SMOEO 200, SMOEO 400, and SMOEO 600. Based on the results, a dose-dependent decrease was observed on days 21 and 42 in serum adiponectin and T3 in the stress and stress-free groups compared with the control group due to MOEO supplementation. The lowest decrease was observed in the MOEO 600 mg/kg dose group. In addition, an increase in stressed groups was observed when examining serum citrulline levels, while chemerin levels did not have a statistically significant effect. While the decrease in serum visfatin, T4, and TSH levels on the 21st day did not have a statistically significant effect, a significant effect was determined on the 42nd day. The addition of MOEO at 600 mg/kg to the ration may be beneficial in preventing intestinal damage and inflammation that may occur due to HS.

Peker, Alper Tunga; Böge, Veysel; Bailey, George S.; Wagman, Jeffrey B.; Stoffregen, Thomas A.
We investigated the perception of higher-order interpersonal affordances for kicking that emerged from lower-order personal and interpersonal affordances in the context of soccer. Youth soccer players reported the minimum gap width between two confederates through which they could kick a ball. In Experiment 1, we independently manipulated the egocentric distance of gaps from participants, and the nominal role of the confederates, either as teammates or opponents. In Experiment 2, we additionally varied the direction in which the confederates were facing, either together (i.e., into the gap) or away (i.e., away from the gap). Perceived minimum kickable gap width was larger for farther egocentric distances, when confederates were identified as opponents rather than as teammates, and (in Experiment 2) when confederates faced toward, rather than away from the gap. In both experiments, these main effects were subsumed in statistically significant interactions. We argue that these interactions reveal perception of higher-order interpersonal affordances for kicking that emerged from the simultaneous influence of lower-order affordances. The results are compatible with the hypothesis that these higher-order affordances were perceived, as such, and were not additively combined from independent perception of underlying, lower-order affordances.

The nephrotoxicity mechanisms caused by cisplatin (CP), which is used in the treatment of different types of cancer, include several processes, such as DNA damage, apoptosis, inflammation, and oxidative stress. This study investigated the protective effects of Rhododendron luteum leaf extract (RLE) in a rat model of CP -induced nephrotoxicity. Dimethyl sulfoxide extract of RLE was prepared, and its contents were clarified using liquid chromatography-mass spectrometry (LC-MS -MS). Thirty female Wistar Albino rats were divided into five different groups and sacrificed on the seventh day. Biochemical and histopathological analyses were then performed. The presence of quercitrin, quinic acid, chlorogenic acid, protocatechic acid, isoquercitrin, and quercetin was detected in the RLE. While CP significantly increased the levels of oxidative stress, inflammation, and apoptosis markers in the rat kidney tissue and blood samples, treatment with RLE significantly reversed the levels of these parameters in a dose-dependent manner. Total antioxidant status (TAS) values and glutathione (GSH) levels increased significantly in the serum samples from the treatment group compared to the CP group, while blood urea nitrogen (BUN), creatinine, oxidative stress index (OSI), tumor necrosis factor-alpha (TNF-alpha), malondialdehyde (MDA) and total oxidant status (TOS) values decreased significantly. GSH levels increased significantly in the treatment group compared to the CP group, while TNF-alpha, caspase-3 (Casp-3), 8-hydroxy-2'-deoxyguanosine (8-OHdG), OSI, TOS, MDA levels, and damage scores decreased significantly at histopathological examination. In conclusion, RLE exhibited strong protective effects against nephrotoxicity and oxidative damage caused by CP in rats.

The Firtina Valley forests are of the 100 forests in the world whose conservation is a priority due to the natural old forests they have. In this study, the epiphytic bryophyte vegetation of the Buxus sempervirens L. forests located in the Firtina Valley (Rize, Northern Turkey), which is one of the nine hotspots in Turkey and Turkey's only boxwood forest, was investigated. The releves taken from living tree trunks in 2020 were analyzed according to the Braun-Blanquet methodology, and ordinated and classified using the Detrended Correspondence Analysis (DECORANA) and the Two-Way Indicator Species Analysis (TWINSPAN). As a result of the analyses, Exsertotheco crispae-Allenielletum besseri ass. nov. subass. typicum and leucodontetosum sciuroidis subass. nov., and Alleniello besseri-Palamocladietum euchloronis ass. nov. were described and characterized. All syntaxa were presented by analyzing them in terms of their ecological and floristic classifications.

Olcay Karaoğlu
Tedavi, bakım ve acil müdahale sorumluluğu olan sağlık personellerinin mesleki gelişiminin sağlanabilmesi için sağlık eğitiminin teorik ve beceri anlamında yeterli düzeyde olması gerekmektedir. Ülkemizde sağlık programlarında yürütülen öğretim faaliyetlerinde dersler farklı eğitim metotları ve araçlarıyla yürütülmektedir. Bu çalışmada yüksek öğretim kurumlarının sağlıkla ilişkili programlarında yürütülen derslerde kullanılan eğitim metot ve araçlarının, öğrencilerin bilgi ve uygulama becerisi üzerindeki etkileri ölçülmeye çalışılmıştır. Çalışmada İlk ve Acil Yardım Programı'nda öğrenim gören 90 öğrenci, 3 gruba bölünerek, her bir gruba farklı eğitim metodu ile triaj anlatılmıştır. Kullanılan eğitim metotları; temel eğitim metodu, simülasyon eğitimi ve uzman desteği alınan eğitim metodu şeklindedir. Veri toplama aracı olarak Aghababaeian ve diğerlerinin (2012) İngilizce olarak geliştirdiği, Aslan'ın (2018) çalışmasında Türkçe ye çevirdiği "Triyaj Bilgi Düzeyi" ve "Triyaj Beceri Düzeyi Belirleme" ölçekleri kullanılmıştır. Verilerin analizleri SPSS 22 paket programı ile gerçekleştirilmiştir. Aritmetik ortalama, yüzde, standart sapma ve frekans dağılımı değerleri verilmiştir. Ortalamalar "Wilcoxon T Testi" ve "Kruskal-Wallis H Testi" kullanılarak karşılaştırılmıştır. Sonuç olarak simülasyon destekli vaka uygulamaları yapılan eğitim grubunda anlamlı farklılık gözlenmiştir. Ancak diğer eğitim metodu uygulanan gruplarda anlamlı farklılıkla karşılaşılmamıştır.

Fevziye Bekar
Proaktif davranış konusu, işgörenlerin kuruma faydası olacak şekilde kendi hedefleri doğrultusunda inisiyatif alması ve başarılar elde etmesini ifade etmektedir. Bu araştırma kapsamında, işgörenlerin işlerine atfettikleri olumlu (işin anlamlılığı) ve olumsuz (işe yabancılaşma) iş tutumlarının proaktif davranış ile ilişkisi; bu ilişkide işte kendini geliştirmenin aracılık etkisi incelenmektedir. Duygusal olaylar teorisi ve tutum-davranış yaklaşımı temelinde ele alınan bu araştırma "proaktif davranış öncüllerinin belirlenmesinde negatif ve pozitif etmenler nelerdir?"; işgörenler, hem negatif hem de pozitif tutumlara aynı anda sahip olduklarında "negatif ve pozitif etmenlerin proaktif davranış ile ilişkisi nasıl olmaktadır" araştırma sorularına cevap aramaktadır. Bu çalışma kapsamında üç farklı araştırma yürütülmüştür. Birinci araştırma kartopu örneklem yöntemi ile 922 sağlık çalışanı üzerine yürütülmüştür. Araştırma sonucunda işin anlamlılığı ile proaktif davranış arasında pozitif ve anlamlı bir ilişki olduğu; bu ilişkide işte kendini geliştirme (öğrenme ve canlılık) değişkeninin aracılık etkisi olduğu sonucuna ulaşılmıştır. İşe yabancılaşmanın bu mekanizmayı negatif yönlü etkilediği bulgulanmıştır. Birinci araştırmada kesitsel ve tek kaynaktan veri toplandığı için ilave bir araştırmaya ihtiyaç duyulmuştur. İkinci araştırma, kolayda örneklem yöntemi ile seçilen mobilya sektöründe faaliyette bulunan 408 personel üzerinde yürütülmüştür Çalışanlar ve yöneticiler olmak üzere iki farklı kaynaktan veri toplanmıştır. İşin anlamlılığı ve işte kendini geliştirme (öğrenme ve canlılık) ile proaktif davranış arasında anlamlı ve pozitif yönlü bir ilişki bulunmuştur. Üçüncü araştırma 209 akademisyen üzerinde yürütülmüştür. Nedensel ilişkileri tespit edebilmek için iki farklı zamanda boylamsal olarak veri toplanmıştır. Araştırma sonucunda, işin anlamlılığı ile proaktif davranış arasındaki ilişkide işte kendini geliştirmenin (canlılık) aracı bir role sahip olduğu sonucuna ulaşılmıştır.

Aylin Karakurt
SOS5 lokusu (FLA4), bitkilerin tuz stresi koşullarında hücre yüzeyi yapışma proteinini kodlar ve normal hücre genişlemesi, hücre çeperi bütünlüğü, yapısını devam ettirmede gereklidir. Bu genin mutasyonuyla oluşan sos5 (fla4) mutantı, tuz stresi altında, anormal kök genişlemesiyle kısa ve şişman kök fenotipi sergilemektedir. ABA'nın bu fenotipi baskıladığı bilinmektedir. Çalışmamızda, Arabidopsis thalina mutant bitki Cd stresi altında benzer bir kök fenotipi sergilemiştir. Bu durumun Absisik asit (ABA) hormonuyla ilişkili olarak, fizyolojik, biyokimyasal ve moleküler düzeydeki etkileri bilinmemektedir. Bu amaçla, çalışmada 50 µM Cd stresi altında dıştan 5 µM ABA muamelesi ile mutant sos5 bitkisinin büyüme ve gelişmesi, içsel Cd miktarları, lipid peroksidasyonu, prolin, hidrojen peroksit (H 2 O 2 ) miktarları, süperoksit dismutaz (SOD), katalaz (CAT) ve askorbat peroksidaz (APX) enzimlerinin aktiviteleri belirlendi. Stres uygulamasının ardından, RNA izolasyonu yapıldı ve cDNA'lar sentezlendi. ABA1, CYP707A3, RD29A ve RD29B genleri ters transkriptaz enzimi ile analiz edildi. Elde edilen bulgulara göre, Cd stresi altındaki sos5 mutant bitkilere dıştan ABA uygulamasıyla yalnız Cd stresi altındakilere göre, mevcut hücresel hasar ortadan kalkmış, içsel H 2 O 2 değeri azalmış, prolin miktarı artmış ve antioksidan enzim aktiviteleri indüklenmiştir. Bu değişimlere bağlı olarak, mutant bitki fenotipik olarak yabani tipe oldukça benzerlik göstermiştir. Cd stresi altında mutant bitkilerdeki ABA ilişkili gen ifadelerinin yabani tipe göre düşük olduğu belirlenmiştir. Cd stresi altında dışarıdan ABA uygulamasının bitkilerdeki içsel Cd miktarını, sadece stres uygulanan gruplara kıyasla, önemli ölçüde düşürdüğü görülmüştür. Çalışmamızda SOS5 gen lokusunun sadece tuz stresiyle ilişkili olmadığını, aynı zamanda Cd stresi koşullarında da hücre duvarı bütünlüğünü sağladığını göstermesi bakımından önemlidir. Elde edilen bulguların, literatürde önemli katkılar sağlayacağı düşünülmektedir.
