Meriç, Çağdaş Salih; Yabanci Ayhan, Nurcan; Yilmaz, Hacı Ömer
Background/Purpose: This study was carried out to evaluate the nutritional status of elderly who received home health care. Methods: A total of 120 elderly were included in this cross sectional study. Elderly were visited in their homes and nutritional status of them was evaluated by Mini Nutritional Assessment-Short Form (MNA-SF) scale. In questionnaire; general information about elderly, presence of chronic disease, pressure sores, anthropometric measurement, nutritional status of elderly were asked. In addition, current biochemical parameters which were routinely evaluated in elderly were recorded by the researcher. Results: The mean age of elderly (40 males and 80 females) was 81.3±8.3 (65-105) years, and 97.5% of elderly were diagnosed with at least one disease. According to the MNA-SF score, 60.8% of elderly were classified as malnourished, 34.2% at risk for malnutrition and 5.0% as normal nutritional status. Currently, 49.2% of malnourished elderly have pressure sores and 54.8% had at least once before; these rates were higher than elderly without malnutrition (p <0.001). In addition, total MNA-SF score of elderly is strongly positive with hemoglobin, hematocrit and calf circumference; it was found that there was a strong negative correlation with C-reactive protein (CRP). Conclusion: In this study, it was found that only 5.0% of elderly who received home health care were in good nutritional status and pressure sore was higher in elderly who have risk of malnutrition or malnourished. Nutritional status of elderly receiving home health care should be evaluated by dietitians and more comprehensive scientific studies are needed.

Kutlu, Elif Ceren; Durusoy, Beyza; Ozden, Talat; Akinoglu, Bulent G.
Turkey, which has immense solar potential, has recently shifted towards solar energy and new renewable energy deployment regulations, including implementation and commercializing rooftop PV technologies. Thus, these require a detailed assessment to determine the power source's capability and convince the policymakers. To the authors' best knowledge, there is no available data or a city-based study for the rooftop PV potential in Turkey. Here, we present the first city-based rooftop PV potential study in Ankara. The technical PV potential calculations are sensitive to the suitable area ratio, module efficiency, and module area assumptions. This study proposes a new, free, reliable, and open-source model for estimating the rooftop PV potential, and it is adaptable to every roof type. The suitable roof area for PV panels is calculated using Helioscope software. Five different modules with different efficiencies and module sizes are modelled in Helioscope. The results showed that Ankara's total technical PV potentials for residential, public, and commercial buildings are 1.15 TWh/year, 55 GWh/year, and 26.8 GWh/year, respectively. Best results are obtained by Mono-Si Halfcut (M2) and Thin Film (M5) modules in residentials, M2 and Mono-Si Bifacial Modules (M3) in Public and Commercial Buildings.

Şahin, Ceyda Uzun; Kulakaç, Nurşen
As in the whole world, the Novel Coronavirus (COVID-19) pandemic poses many threats to healthcare workers in our country too, which leads to anxiety in healthcare workers. This study was conducted to explore the anxiety levels of healthcare workers during the COVID-19 pandemic. The study is a cross-sectional study. The population consisted of health care workers employed in hospitals in seven regions in Turkey. All volunteer healthcare workers were included in the study, and 356 healthcare workers responded to the questionnaire. The data were collected using the State Anxiety Inventory and a questionnaire created by the researchers using an online questionnaire between 10 May 2020 and 15 May 2020. In the evaluation of the data, mean, standard deviation, percentages, t-test, one-way ANOVA, Pearson correlation, and multiple regression analysis were used. 33% of healthcare workers did not have anxiety, 50% had mild, and 17% had severe anxiety. The anxiety scores of those who were nurses (p < 0.001), who were working in the emergency room (p < 0.001), who were involved in treatment for COVID-19 patients (p = 0.040), who left their homes to prevent transmission to their families and relatives during the pandemic (p = 0.038), and whose working hours had changed (p = 0.036) were found to be significantly higher. It was observed that there was a positive and significant relationship between the fear of death and disease transmission, uncertainty, loneliness, anger, and hopelessness, and anxiety levels in healthcare workers. The main factors that significantly affected the anxiety levels of healthcare workers were male gender, weekly working hours, the presence of chronic diseases, and feelings of anger and uncertainty. In conclusion, during the COVID-19 pandemic, healthcare workers experienced some negative emotions, their anxiety levels increased, and they were psychologically affected. Planning psychosocial interventions for healthcare workers in the high-risk group will make significant contributions to the health system.

Sirat, Abdulveli; Bahar, Bilge; Bahar, Necmiye
Triticale is an important alternative crop and is largely grown on marginal lands in Turkey to overcome the shortage of rising animal feed problem. Sometimes Triticale is also used as human food. This study was conducted for two years between 2013-2014 and 2014-2015 to determine some grain quality characteristics of nine different Triticale (Tatlicak-97, for cvs. Presto, Karma-2000, Melez-2001, Mihkam-2002, Ege Yildizi, Alperbey, Umranhanım, and Tacettinbey) cultivars under dry farming conditions at Siran-Gumushane (Eastern Black Sea Region, Turkey). The experiment was conducted with three replications based on the randomized complete block design. According to two-years average, thousand-grain weight of cultivars changed from 38.85-45.12 g, also, hectoliter weight 74.68-77.21 kg hl-1, protein contents 10.56-12.09%, starch contents 64.74-68.19%, moisture contents 9.44-9.72%, ash contents 1.25-1.60%, oil contents 0.79-1.27%, ADF (acid detergent fiber) 3.22-4.39%, NDF (neutral detergent fiber) 15.14-16.88%, potassium (K) contents 0.432-0.527%, magnesium (Mg) contents 0.113-0.135%, and phosphorus (P) contents 0.360-0.387%. In terms of quality characteristics, the maximum thousand-grain weight was obtained from Tacettinbey and Ege Yildizi; the maximum grain yield weight from Tatlicak-97; the maximum hectoliter weight from Tatlicak-97, Ege Yildizi and Mihkam-2002 cultivars; Also, cv. Karma-2000 and Alperbey had the maximum protein contents, and Umranhanım and Mihkam-2002 cultivars had the maximum starch content. It is concluded that studies relating to Agronomic practices of these and other Triticale cultivars would help in improving the life style and the livestock sector of the region.

Şenaslan, Fatih; Çelik, Ayhan; Taşdemir, Muharrem
Magnesium oxide (MgO) thin films were deposited on silicon and glass substrates by the radio frequency (RF) sputtering method. The MgO films were annealed at 400 ⁰C for 4h. The effect of working pressure on the structure and optical properties of MgO films was investigated. Structural characterization of thin films was determined using the X-ray diffraction (XRD) method. XRD results showed the presence of dominant peaks corresponding to the (200) and (220) lattice planes of MgO. However, peaks corresponding to (111), (311) and (222) lattice planes of the MgO also appeared in the films deposited at low pressure. It was determined that the average crystal size decreased as the working pressure reduced, while the deposition rate increased. SEM analysis showed that the microstructure of the nano-spherical MgO film transformed into a coarse-grained nano-pyramidal shape after annealing. The optical properties of MgO films were investigated by UV-Vis spectroscopy. Accordingly, it was determined that the absorption threshold of the films was around 310 nm wavelength and the optical band gap of the films varied between 4.07 and 4.14 eV. As a result, MgO films with high transmittance reaching an average of 95% in the visible region were obtained.

Yanik, Yusuf; Türker, Temel; Çalik, Ismet; Yildirim, Ömer
Historical structures are important pieces that connect past to present. Historical structures damaged for various reasons should be restored, repaired and strengthened. After these processes, the behavior of historical structures affected by environmental and time-dependent effects should be followed. For this purpose, current structural behavior of historical structures should be determined. Methods based on the dynamic characteristics of structure are very effective in the evaluation of structural behavior. In this study, dynamic characteristics of Tabakhane and Haci Kasim Muhittin Mosque Minarets in Trabzon province with different environmental conditions and different time intervals were experimentally obtained and compared. Experimental measurements of these minarets were carried out under environmental vibrations with Civil Engineering Vibration System (CEVS), which was developed by our research team, which can receive wired and wireless data. In Tabakhane Mosque Minaret, two measurements taken at different times before restoration and two measurements taken at different times after restoration were evaluated and compared each other. Measurement results of Haci Kasim Muhittin Cami Minaret before and after restoration and two measurements results taken at different times long after restoration were evaluated. The measurement data were analyzed separately in Civil Engineering Vibration Analysis (CEVA) program developed by our research team and in ARTEMIS program. In addition, dynamic characteristics obtained as a result of signal processing for both minarets were compared with previous studies. The reasons for differences in these values were examined depending on environmental condition and time.

In this research, the microbiological, physicochemical, rheological, textural, sensory properties and antioxidant activity of blueberry pulp added (0, 4%, 8% and 12%) strained yoghurt samples were investigated during a 28 day storage period. The Lactobacillus delbrueckii spp. bulgaricus and Streptococcus thermophilus counts in the samples were found to have decreased at the end of the storage period. The lightness, yellowness/blueness and whiteness index values showed a decrease depending on the addition of blueberry, while the redness/greenness values increased. The addition of blueberry had a negative the effects on the fat and protein values, while it had a positive effect on the total solids values. The storage period did not significantly change any of the physicochemical, colorimetric or rheological properties of the strained yoghurt samples. The general acceptability scores of the sample containing 12% blueberry were higher than the other samples. The antioxidant activities and total phenolic content of the strained yoghurt samples increased in accordance with blueberry concentration, while the firmness and work of the shear values decreased. In conclusion, it was determined that the addition of blueberry pulp at a 12% ratio could be used to enhance the nutritional and functional properties of strained yoghurts.

Manshouri, Negin; Melek, Mesut; Kaylkcloglu, Temel
Despite the long and extensive history of 3D technology, it has recently attracted the attention of researchers. This technology has become the center of interest of young people because of the real feelings and sensations it creates. People see their environment as 3D because of their eye structure. In this study, it is hypothesized that people lose their perception of depth during sleepy moments and that there is a sudden transition from 3D vision to 2D vision. Regarding these transitions, the EEG signal analysis method was used for deep and comprehensive analysis of 2D and 3D brain signals. In this study, a single-stream anaglyph video of random 2D and 3D segments was prepared. After watching this single video, the obtained EEG recordings were considered for two different analyses: the part involving the critical transition (transition state) and the state analysis of only the 2D versus 3D or 3D versus 2D parts (steady state). The main objective of this study is to see the behavioral changes of brain signals in 2D and 3D transitions. To clarify the impacts of the human brain's power spectral density (PSD) in 2D-to-3D (2D_3D) and 3D-to-2D (3D_2D) transitions of anaglyph video, nine visual healthy individuals were prepared for testing in this pioneering study. Spectrogram graphs based on short time Fourier transform (STFT) were considered to evaluate the power spectrum analysis in each EEG channel of transition or steady state. Thus, in 2D and 3D transition scenarios, important channels representing EEG frequency bands and brain lobes will be identified. To classify the 2D and 3D transitions, the dominant bands and time intervals representing the maximum difference of PSD were selected. Afterward, effective features were selected by applying statistical methods such as standard deviation, maximum (max) and Hjorth parameters to epochs indicating transition intervals. Ultimately, k-nearest neighbors, support vector machine and linear discriminant analysis (LDA) algorithms were applied to classify 2D_3D and 3D_2D transitions. The frontal, temporal and partially parietal lobes show 2D_3D and 3D_2D transitions with a good classification success rate. Overall, it was found that Hjorth parameters and LDA algorithms have 71.11% and 77.78% classification success rates for transition and steady state, respectively.

Komut, Osman
The Covid 19 pandemic has led to considerable destruction of social and economic areas at a global level. This study aims to determine the economic impact of the Covid 19 pandemic on the Turkish forestry sector. In this context, 5 years (from 2017 to 2021) of wood-based product sales of an administrative unit, which carries out regional forestry activities in Turkey, were studied. The data concerning the product groups were subjected to a Laspeyres price index analysis based on the base period weight through the price and estimated price increase rate variables. In addition, correlation analysis was utilized to determine the relationships between the determined variables. The findings showed that the Covid 19 pandemic led to decreases in the Laspeyres price index values for the price and estimated price increase rates when compared with the pre-pandemic period, which was different on a product group’s basis. As a result, it can be said that the Covid 19 pandemic process created a considerable potential for a loss of income in wood-based products, which is one of the primary outputs of the forestry sector, and as of 2021, a recovery process has started.

Excavability is a measure of material which can be excavated with classical excavation equipment. Studies to decide the rock excavability characteristics contribute to the suitability of engineering projects. In this study, a limestone quarry (in Bayburt, Turkey) was analysed with excavability classification systems and appropriate systems were determined. To accomplish this aim, point load index and Schmidt hardness tests were practiced and changed to uniaxial compressive strength tests. After that, findings were categorized with classification systems in excavation and matched against practices from field. In this study, rock mass was addressed as “pre-explosion”, “hard ripping” and “hammer and blasting” in accordance with distinctive classification systems. All determined as rock mass should be blasted for loosening then dug with hydraulic breakers. This practice is totally compatible with in-site excavations fulfilled. According to study results, the most suitable parameters to decide surface excavational classification are load strength index, geological strength index and the degree of rock mass weathering

Pekmez is a concentrated syrup-like food conventionally produced by vacuum evaporation process from sugar-rich fruits. In this study, the applicability of grape pekmez production by ohmic heating assisted vacuum evaporation (ΩVE) method was investigated. Conventional vacuum evaporation (CVE) and ΩVE methods were compared in terms of physicochemical properties, HMF (5-hydroxymethylfurfural) contents, rheological properties, and energy consumptions. ΩVE was run at four different voltage gradients (17.5, 20, 22.5, and 25 V/cm). Total process times for grape pekmez production were determined as 57, 28.5, 32, 39, and 50 minutes for CVE, ΩVE (25 V/cm), ΩVE (22.5 V/cm), ΩVE (20 V/cm) and ΩVE (17.5 V/cm), respectively. Energy consumption of CVE method was higher than ΩVE method for all voltage gradients. Energy efficiency increased as the voltage gradient increased. There was no significant difference between CVE and ΩVE methods for HMF contents. The results show that the ΩVE method could be an alternative to the CVE process for grape pekmez production.

In the presented research, five different ratios of flaxseed powder (FSP) (0, 0.25%, 0.50%, 0.75%, and 1%) were used in yoghurt production, and the samples were stored overall 28 days at refrigerator (+4 °C). The effect of FSP and the storage period on acidity, pH, syneresis, water holding capacity, rheological, viscosity, colorimetric, microbiological, and sensory properties of yoghurts were investigated. The acidity, syneresis values of yoghurt samples decreased with the addition of FSP, conversely, the pH, water holding capacity values of the samples increased. The increments in the viscosity (50 and 100 rpm) and consistency coefficient values were observed depending upon the FSP ratio except for the sample containing 1% FSP. All yoghurt samples had pseudoplastic flow behavior. It was determined that the colorimetric parameters of samples changed significantly with the addition of FSP. The L* and white index values of samples containing FSP decreased. Other colorimetric parameters indicated significant differences based on the addition of FSP and storage. The addition of FSP was not caused any negative effect on counts of Lactobacillus bulgaricus and Streptococcus thermophilus. The Lactobacillus bulgaricus, Streptococcus thermophilus and mouldsyeasts counts were consistent with the Codex Alimentarius and the Turkish Food Codex. The sample containing 1% FSP had the lowest evaluation scores in terms of all sensory properties. Therefore, FSP should not use more than 0.75%. Using of the 0.25% FSP in yoghurts could recommend for improve physicochemical, rheological and sensory properties of yoghurts

Arslan, Mehmet; Temi̇Zel, İrfan; Abdi̇Oğlu Yazar, Emel; Ar, Bahrican; Yücel, Cem
The highly siderophile element (HSE) or platinum group element (PGE) and Os isotope systematics of basaltic volcanics have recently received a significant attention because of their potential to constrain the petrological processes on magma generation and evolution. The HSE and Os isotope data, which are generally observed at very low concentrations in basalts and obtained by modern enrichment and analytical techniques, are frequently used in petrological studies. The HSE contents and ratios from whole-rock analysis of basalts, and combined evaluation with the theoretical knowledge and modelling of HSE behaviour during the partial melting of mantle and the differentiation of basaltic magma would provide opportunity for geochemical modelling on mantle melting. Besides, HSE contents and Pd-PGE/Ir-PGE ratios are important indicators for the nature of mantle sulfides, the sulfur saturation conditions of the mantle source, sulfide segregation, fractional crystallization, crustal assimilation and partial melting degrees in the origin and evolution of mantle-derived magmas. Therefore, in addition to the traditional whole-rock geochemical data obtained from Cenozoic aged basalts observed widely in Turkey, HSE and Os isotope systematics of these basalts can contribute to define the geochemical features of the mantle source, and to model petrological processes which are effective in the magma evolution.
