A quasi-boundary method for solving an inverse diffraction problem
Authors: Li Zhenping , Xiong Xiangtuan , Li Jun , Hou Jiaqi
Published: April 2022

In this paper, we deal with the reconstruction problem of aperture in the plane from their diffraction patterns. The problem is severely ill-posed. The reconstruction solutions of classical Tikhonov method and Fourier truncated method are usually over-smoothing. To overcome this disadvantage of the classical methods, we introduce a quasi-boundary regularization method for stabilizing the problem by adding a-priori assumption on the exact solution. The corresponding error estimate is derived. At the continuation boundary $ z = 0 $, the error estimate under the a-priori assumption is also proved. In theory without noise, the proposed method has better approximation than the classical Tikhonov method. For illustration, two numerical examples are constructed to demonstrate the feasibility and efficiency of the proposed method.
Identification of drug side effects with a path-based method
Authors: Jiang Meng , Zhou Bo , Chen Lei
Published: April 2022

The study of drug side effects is a significant task in drug discovery. Candidate drugs with unaccepted side effects must be eliminated to prevent risks for both patients and pharmaceutical companies. Thus, all side effects for any candidate drug should be determined. However, this task, which is carried out through traditional experiments, is time-consuming and expensive. Building computational methods has been increasingly used for the identification of drug side effects. In the present study, a new path-based method was proposed to determine drug side effects. A heterogeneous network was built to perform such method, which defined drugs and side effects as nodes. For any drug and side effect, the proposed path-based method determined all paths with limited length that connects them and further evaluated the association between them based on these paths. The strong association indicates that the drug has a side effect with a high probability. By using two types of jackknife test, the method yielded good performance and was superior to some other network-based methods. Furthermore, the effects of one parameter in the method and heterogeneous network was analyzed.

Published: April 2022

This study aimed to investigate the relationships between atmospheric parameters, seawater quality and green mussel production which were cultured in pond, estuary and coastal areas. Seawater and mussel samples were collected from mussel farms in the inner Gulf of Thailand from January to December 2019. Climate data were obtained from the Thai Meteorological Department. The correlations between selected atmospheric and seawater parameters were developed using linear and non-linear models. The influence of seawater quality on mussel production was evaluated using principal component analysis and stepwise multiple linear regression. The effects of atmospheric variation on green mussel productivity were simulated. The results showed that high air temperature and rainfall caused an increase in seawater temperature and a decrease in salinity, respectively. It was observed that the most influential factors affecting mussel production were nutrients and dissolved oxygen in ponds, temperature and salinity in estuaries, and nutrients and pH in coastal areas. The simulation indicated that mussel production can deteriorate when air temperature reaches 34°C and rainfall is higher than 200 mm per month. Our results suggest that under climate change events, locations with less riverine influence can provide higher mussel productivity. These results can be used as a guideline for farmers during a climate change event.
Fishery dynamics of blue whiting, Micromesistius poutassou, a highly discarded bycatch species in the NW Mediterranean Sea
Authors: Mir-Arguimbau Joan , Martín Paloma , Balcells Marc , Sala-Coromina Joan , Sabatés Ana
Published: April 2022

This study characterized the fishery dynamics of blue whiting, a bycatch species of the bottom trawl Norway lobster fishery, in the NW Mediterranean. Landings and effort data over the last two decades were combined with current information on the spatial distribution of effort and catch, and with the size and age structure of blue whiting over the year. Recruitment to the demersal habitat occurred from 5 cm total length (TL) over the shelf break in spring (April-May), when discards showed the highest values (>95% of the catch). Adults were located over the upper slope, and large individuals (≥26 cm TL) were abundant during the reproductive period (January-March). A decline in landings has been observed in the last decade, probably related to the absence of intense deep convection processes in winter since 2013, which favour recruitment of the species. The effect of exploitation on the decrease in landings cannot be disregarded considering that the bulk of the catch is made up of immature (age 0) individuals, and the presence of old individuals is very low.

Authors: Gasmi Mohamed , Bendib Issam , Benmabrouk Yasmina
Published: April 2022

In the medical field, the diagnostic phase is the most important, as the entire treatment process will be based on this step. Oncological diseases such as breast cancer require a precise anatomopathological study accompanied most of the time by an immunohistochemical study whose goal is to know the sensitivity of tumor tissues to hormone therapy and targeted therapy. This study relies on antibodies and their interpretation requires significant time and as it can suffer from poor reproducibility which negatively influences the treatment stage. In this work, the objective is to classify histopathological images stained with E-cadherin antibody to help pathologists in their work in order to facilitate oncologists in the choice of the most appropriate therapeutic protocol. The realization of this task is based on the choice of transfer learning as techniques and data augmentation due to the minimal number of images gathered. The results obtained are very satisfying both on accuracy where we reached a rate of 97.27% with a reduced number of parameters and very close to our basic model.

Authors: Ombres Luciano , Guglielmi Marielda , Verre Salvatore
Published: April 2022

The paper refers to the results of an experimental investigation on partially FRCM confined clay brick masonry. Seven small-scale masonry columns (square cross-section 250x250 mm, overall height 770 mm) were tested under monotonic centred load until collapse. The confining system (basalt-FRCM, SRG) and the number of the confining layers (i.e., 1, 2, and 3) were the varied parameters. Failure modes, load-displacements curves (both axial and transversal) and peak loads were reported and discussed in the paper. The performed research aims to contribute to the knowledge in the field of FRCM/SRG-confinement, mainly focusing on the influence of some of the mentioned parameters. The obtained results could be considered for the validation or the improvement of analytical design-oriented formulas.
The Contribution of Glass Microspheres and PP Fibers in the Properties of NHL Grouts
Authors: Baltazar Luis G. , Botas João
Published: April 2022

Although, over the last decades, different types of additions have been used in mortars for conservation of heritage buildings, their use in lime-based grouts for stone masonry consolidation is limited. The purpose of this study is to contribute to the increase of knowledge regarding the performance of injection grouts prepared with glass microspheres and polypropylene (PP) fibers. The effects of glass microspheres and PP fibers on the properties of natural hydraulic lime-based grouts were analysed by rheological measurements, mechanical strength tests, water absorption and drying test. The content of glass microspheres (5-20%) and PP fiber (0.1-0.5%) was added by the weight of binder and to reduce the water demand, a polycarboxylate superplasticizer was used. From the assessment of the results, it was asserted that the fresh state behaviour was slightly affected by these additions, as in general the rheological properties worsened compared to the reference grout composition. On the other hand, the PP fibers influenced the hardened grouts’ properties in a positive way, while their mechanical and physical properties were slightly improved or maintained which is a crucial feature for the success of consolidation intervention.

Authors: Naghizadeh Abdolhossein , Ekolu Stephen O. , Solomon Fitsum
Published: April 2022

Geopolymers are known to be environmentally – friendly construction materials that can be used in different applications including concretes and mortars, fire – resistant coating materials, road pavements and masonry units. Despite the economic and environmental – related benefits of utilizing geopolymer products, the production of these materials is also associated with some challenges and difficulties that need to be resolved for the technology to gain recognition and acceptability in the construction industry. In this paper, publications were reviewed to provide some understanding of the problems and challenges of geopolymer brick production. Composition of alkali activator along with curing temperature, are major factors that significantly influence the production cost of geopolymer bricks. Also, incorporation of calcium - rich co - binders into geopolymer mixtures, may lead to reduction in durability resistance of the brick product.
A Novel Composite Reinforced Mortar for the Structural and Energy Retrofitting of Masonry Panels
Authors: Longo Fabio , Cascardi Alessio , Lassandro Paola , Aiello Maria Antonietta
Published: April 2022

Existing masonry buildings become more and more outdated depending on the actual state of conservation, but also in relation to the renovation of the performance requirements stated in current code and guidelines. Therefore, two fundamental aspects emerge as drawbacks: mechanical resistance and thermal conductivity. The structural retrofitting often consists of a covering by means of Composite Reinforced Mortar (CRM), which involves a pre-impregnated fiber mesh into an inorganic binder (e.g. lime-based mortar), while an additional insulation layer is designed for thermal scope. In this study a new composite, concerning a fly-ash based geopolymer and a glass fiber mesh (namely Composite Reinforced Geopolymer Mortar - CRGM), is proposed. The goal is to demonstrate its ability of improving both the shear strength and the thermal resistance of a masonry panel (simulating an existing structure). At this scope, an experimental investigation put in contrast the proposal with respect to a traditional CRM-system (i.e. lime-based matrix and the same glass fiber mesh). The results confirmed the validity of the CRGM. Moreover, a theoretical simulation evidenced the potential impact of the CRGM on the commonly used types of masonry all around Italy from the thermal point of view.

Authors: Monaco Alessia , D'Anna Jennifer , Minafò Giovanni , La Mendola Lidia
Published: April 2022

This paper presents a critical review of the most established analytical models for the prediction of the compressive strength of FRP and FRCM-confined masonry columns. In particular, two types of fibres are analysed, i.e. glass and basalt. A wide dataset available in the literature is used for the application of the analytical models and for the development of parametric analyses useful for the critical comparison of FRP vs. FRCM confinement technique and glass vs. basalt fibres to be adopted as reinforcement of masonry substrate. The effects of stiffness and strength of the reinforcement, the number of reinforcing layers, the compressive strength of masonry and the cross-section shape are investigated.
Load Bearing Capacity of Masonry Arch Constructed by Means of a Patented Method: A Preliminary Study
Authors: Cascardi Alessio , Micelli Francesco , Aiello Maria Antonietta
Published: April 2022

Arch is a structural member which provides aesthetic beauty to architectures and, at the same time, guarantees stability to structures. For this reason, it was largely adopted for masonry building in the past centuries. Nonetheless, the erection of new curved structures is poorly considered in modern time. One of the possible causes is the difficulty of constructing since it requires the use of temporary scaffolding. Thus, it may results time-and cost-consuming. Innovation in the field of arch construction is very rare until now. The present paper aims to validate a novel construction method for curved members by means of small-scaled specimens. The proposed method consists of connecting the stone blocks on one side with Fibre Reinforced Polymer (FRP) and then lift it up. The herein experimental program involved masonry arches loaded at the mid-line in order to compare the behaviour of the traditionally-made and the innovative arches in terms of load-bearing versus deflection. This is a preliminary test within a larger ongoing experimental campaign.
Experimental Investigation on the Bond Behaviour of Masonry Element Strengthened with Carbon-TRM and Steel-TRM
Authors: Wang Xuan , Lam Chi Chiu , Zhang Zi Hua , Zhu Yao Hong
Published: April 2022

Textile reinforced mortar (TRM) composites are an innovative solution for strengthening existing structures. TRM composites are produced with high-strength textile embedded in inorganic mortar matrices, demonstrating compatibility with existing masonry. As TRM is externally bonded to the surface of the structure, the bond behaviour between TRM and masonry substrate is a critical issue to investigate. In this study, experimental research aims to deeply understand the bond behaviour of TRMs for strengthening masonry structures. The experiments mainly consist of a series of single-lap shear bond tests on TRMs to masonry substrates. Two types of textiles (carbon and steel textile) combined with two mortar matrices (cement and lime-based mortar) were used to construct TRM. The effect of the textile and mortar matrix is presented. The test results are discussed in terms of the full range of load-slip responses and failure modes. The result showed that TRM with steel textile and cement-based mortar matrix offers better bond behaviour, but the risk of masonry damage should also be considered.
Modelling of Curved Masonry Elements Reinforced with TRM: From a Detailed to a Simplified Approach
Authors: Scacco Jacopo , Milani Gabriele
Published: April 2022

Numerical modeling of curved masonry structures reinforced with TRM can be particularly demanding. Indeed, several failure typologies can be encountered when a masonry element is reinforced with this strengthening solution. In the case of arches and vaults, the curvature itself complicates furtherly a correct prediction. The paper wants to provide a reasonable way to model numerically curved masonry structures reinforced with TRM and explore the advantages and detriments of advanced simulation and simplified approaches. At first, an advanced micro-modeling is applied to an arch reinforced at the extrados. Then, the same approach is applied to a limited portion of the same arch and numerical lap shear tests are performed. Finally, a simplified model equipped with a set of truss elements is proposed.

Published: April 2022

Fiber Reinforced Cementitious Matrices (FRCM) represent a very efficient strengthening solution for the improvement of the structural behavior of existing masonry constructions. However, the mechanical performances of these materials could be significantly affected by different environmental conditions, such as the exposure to thermal stresses. This aspect should be properly assessed for a correct design of the strengthening interventions. The Italian Guidelines for the identification, qualification and acceptance control of FRCM systems to be used for the structural strengthening of existing constructions prescribe the execution of direct tensile tests on FRCM coupons to evaluate the behavior of these composite systems subject to thermal stress. Within this framework, the objective of the present research is to evaluate the effect of a thermal stress on the tensile behavior of three different FRCM systems, composed by steel or basalt fibers and lime-based or cement-based mortar matrix. Tensile tests are performed, for each system, on samples at ambient temperature (22°C) and on samples conditioned at 80°C for six hours, according to the indications provided by the Guidelines. The test results show that the effect of the thermal stresses is more evident in the first phases of the tests, i.e. during the elastic phase and the mortar matrix cracking phase, while it is less significant in the last phase, which is related to the fibers behavior. The tensile strength of the investigated FRCM systems is, indeed, within the limits provided by the Italian Guidelines, while the curves of the conditioned samples may deviate from the reference ones at the beginning of the tests. These findings are critically discussed within the paper.
Abandoned Mine Tailings and Coal Ash Industrial Wastes for Sustainable Production of Geopolymer Brick Masonry: South African Case Study
Authors: Ekolu Stephen O. , Solomon Fitsum , Naghizadeh Abdolhossein
Published: April 2022

In various countries, a variety of waste by-products are disposed-off to the local environment, mostly due to lack of innovative initiatives for their utilisation. With human population growing strongly in most developing countries such as in Africa etc., lack of housing has become an endemic concern exacerbated by poverty and unaffordability of conventional construction products. Geopolymer technology provides new insights and possibilities into potential utilisation of a variety of mining and industrial waste by-products, currently being dumped in landfills leading to environmental pollution. This paper focusses on mining and industrial waste products that are currently not being utilised. In South Africa, mine tailings and bottom ash, also colloquially referred to “ash dumps”, exist in enormous quantities. Moreover, some of these waste products are presently an environmental menace responsible for discharge of acid mine drainage found in different geographical locations. The present study reviewed the potential utilization of mine tailings for brick making based on geopolymer technology. Also discussed are risks, hinderances and challenges to waste utilization including lack of public confidence attributed to radioactivity of some tailings-based brick products. While drawing from literatures worldwide, emphasis is placed on environmental and economic benefits of utilising these otherwise disregarded waste materials, to meet local societal needs of poor communities.

Published: April 2022

Despite the higher thermal conductivity and the higher lifetime offered by silver sintering technologies, most packaged GaN devices are attached using solders due to technological difficulties in the sintering process. In this work, a silver sintering process for a packaged GaN power transistor on a printed circuit board (PCB) was successfully developed. Different sintering paste types were examined regarding their suitability for this application. Electrical measurements, shear tests, and metallographic cross sections were used for the evaluation. Numerical analyses were used to study the internal stress distribution in the GaN package after sintering depending on the paste structure. In the final sintering process, a shear strength of 20 MPa for sintering at 15 MPa and 240°C, for 300 s with electrical functional devices could be obtained by using nanoscale sintering paste. The authors contribute this to the high initial stiffness of the silver layer, which is obtained much earlier in the sintering process compared with the stiffness of a microscale silver paste. This high initial stiffness counteracts the semiconductor device deflection from the applied sintering pressure and reduces the stresses inside the semiconductor.

Published: April 2022

As more adults are living into old age, they are predisposed to cardiovascular disease (CVD) and the demand for cardiac rehabilitation is increasing. We aimed to verify predictors of length of stay (LOS) in young (Y) vs older (O) vs very old (VO) CVD patients, admitted to residential cardiac rehabilitation. Patients’ demographic and clinical characteristics at admission, as well as Barthel index (BI), Cumulative Illness Rating Scale (CIRS), comorbidity severity/complexity, NYHA classification, left ventricular ejection fraction (LVEF), physical activity level were compared in Y (≤65 years) vs O (between >65 and <76 years) vs VO patients (with an age of ≥76 years) against LOS. In 5,070 consecutively CVD patients were included; they were 1392 Y (38%) 1944 O (35%) 1334 VO patients (27%) and LOS duration was 16±7, 19±9 and 22±10 days, respectively (p<0.0001). In Y, LOS was linked to BI (p=0.000) and to LVEF (p=0.000) at multivariable analysis with area under ROC curve of 0.82, whereas in O, LOS was associated to gender (p=0.013) CIRS severity (p=0.000), BI (p=0.000), LVEF (p=0.000), and in those VO to gender (p=0.004), BI (p=0.000) and medical infusion (p=0.000) at multivariable with ROC curve of 0.83 and 0.74, respectively. In very old patients, a prolonged LOS is related to extra-cardiac conditions. Therefore, we promote a specific cardiac rehabilitation for these patients.

Synthetic agents as growth promoters in aquaculture has become unpopular, hence, the need for better alternatives. This study was conducted to investigate the effects of dietary plants on growth performance, haematological, biochemical and oxidative stress parameters in African catfish. Fish were fed on basal diets for 84 days, the control and six other experimental diets containing different levels of Alstonia boonei (0.5%,1.0% and 1.5%) and Mitracarpus scaber (0.5%,1.0% and 1.5%) of the basal diets. Fish were weighed bimonthly, blood samples were collected and analyzed. At the end of the experiment, the final weight (FW), weight gain (WG), Average Daily Growth Rate (ADGR) and Specific Growth Rate (SGR) of fish fed with A. boonei and M. scaber were significantly higher than that of control (P<0.05). The values of RBC and haemoglobin of the M. scaber (0.5%) group were significantly higher than the other groups including the control. The values of Heterophil-Lymphocyte Ratio (HLR) and Platelet-Lymphocyte Ratio (PLR) in the control group were significantly higher than those of the treatment groups. Biochemical parameters and oxidative stress markers did not show any significant difference between the treatment groups and the control (P>0.05). The findings clearly indicated that the plants enhanced growth performance in fish with little or no deleterious effects.

Published: April 2022

Nervous necrosis virus (NNV) is a devastating infectious pathogen for fish species with 100% mortality. To date, no specific drugs or vaccines have been developed that can prevent infections in aquaculture caused by NNV. It has been found that the NNV utilizes capsid protein to enter into the host cell in Asian sea bass and cause disease. In this study, we evaluated the inhibitory potential of Allium sativum compounds that have been reported to show antiviral activity against various pathogens. The capsid protein was modeled and the binding affinity of all the compounds was calculated with the docking approach and top 2 (PubChem CID: 122130381 and CID 12303662) inhibitory compounds were selected for further ADMET properties and DFT analysis. Both the geometry optimization and redocking of the two inhibitory compounds (PubChem CID: 122130381 and CID 12303662) showed a strong binding affinity of -8.2 and -8.0 kcal/mol, respectively with the capsid protein. The molecular dynamic simulation approach further validated the capsid protein – CID: 122130381 and capsid protein- CID 12303662 complex stability. In conclusion, this study deduces that these Allium sativum phytochemicals might act as significant inhibitors of the NNV in sea bass, which can be further validated experimentally.

Published: April 2022

Giant gourami (Osphronemus goramy) has been known to have a high ability to utilize high dietary carbohydrates. However, its molecular information related to carbohydrate metabolism is still limited. The present study elucidated Giant gourami's liver transcriptome and molecular responses to high dietary carbohydrates. Two semi-purified diets with different levels of dietary carbohydrate, normal carbohydrate (34%, N34) and high carbohydrate (53%, H53), were offered to the fish for 60 days. A total of 87,430,553 clean reads were collected and assembled into 49,034 cDNA contigs. Annotation was performed, and a total of 33,104 unigenes were obtained. High dietary carbohydrates generally down-regulated the differentially expressed genes (DEGs). The genes expression related to glycolysis and the antioxidant system were significantly upregulated (P<0.05). Meanwhile, the genes expression related to insulin signaling and gluconeogenesis were significantly downregulated (P>0.05). The results showed that Giant gourami has several adaptabilities for high carbohydrates. The upregulation of the glycolytic, gpx, and noa1 genes, downregulation of insulin signaling, and gluconeogenic genes indicated a good glucose homeostasis maintenance in Giant gourami.

Metolasen dihalojenür bileşiklerinin, tümör hücrelerine karşı yüksek aktiviteye sahip olduğu gözlenmiştir. Bunun en önemli kanıtı olarak, tümör hücrelerindeki metal iyonu birikimi gösterilmiştir. Biyokimyasal araştırmalar sonucunda metalosen komplekslerinin aktivitesinin merkez iyonundan güçlü bir şekilde etkilendiği tespit edilmiştir. Siklopentadienil (Cp) ligandının yapıdan ayrılmasının metal iyonuna ve çözeltinin pH’sına bağlı olarak değiştiği gözlenmiştir. Örneğin, Ti4+ kompleksinde siklopentadienil halkasının yapıdan ayrıldığı tespit edilirken, V4+ kompleksinde bu durum gözlenmemiştir. Buna bağlı olarak da bu komplekslerin biyolojik aktivitelerinin farklılık gösterdiği belirlenmiştir. Bu derlemede metalosenlerin kimyasal yapısı, metalosen komplekslerinin sentezlenmesi ve tıpta kanser tedavisinde kullanımı üzerine bilgi verilmektedir.

Diyabetes Mellitus (DM), pankreasın yeterli miktarda insülin üretememesi ya da salgılanan insülin hormonunun vücutta etkili olamaması ile ortaya çıkabilen kan şekeri yüksekliği ile karakterize olan bir hastalıktır. DM, prevalansı her geçen gün artmakta olan, morbitide ve mortalitesi yüksek bir hastalıktır. Tedavi için tıbbi beslenme tedavisi; farmakolojik ajanlar, insülin tedavisi uygulanabilmektedir. Tıbbi beslenme tedavileri ülkelere ve yaşam tarzına göre farklılıklar göstermektedir. Genel olarak Akdeniz tipi beslenme ve karbonhidrat sayımı yöntemi uygulansa da farklı diyet modellerinin de DM üzerine olumlu etkileri olduğu görülmüştür. Bu derlemede DM üzerine olumlu etkileri olduğu varsayılan tıbbi beslenme tedavileri incelenmiştir.

Giriş: İnsanlar hastalık belirtilerin, ilaçların yan etkilerini azaltmak ve bağışıklık sistemini güçlendirmek amacıyla geleneksel tamamlayıcı alternatif tedavi yöntemlerine başvurmaktadır. COVİD-19 salgını sürecinde her kesimden insanın tamamlayıcı uygulamalar ve tedbirler kapsamında geleneksel tedavi yöntemlerini, özellikle şifalı olduklarını düşündükleri bitkileri kullandıkları, çocukları için de bu yöntemlere başvurdukları düşünülmektedir.

Amaç: Ailelerin COVİD-19 pandemisi sürecinde çocuklarının sağlığını korumak ve geliştirmek için başvurdukları geleneksel tamamlayıcı alternatif tedavi (GETAT) yöntemlerini belirlemektir.

Materyal Metod: Tanımlayıcı tipte planlanan çalışmanın verileri, araştırmacılar tarafından oluşturulan “Tanıtıcı Bilgi Formu” kullanılarak google form aracılığı ile toplanılmıştır. Bu formda sosyo-demogratif veriler, COVİD-19 pandemisi süreci ile ilgili sorular ve ailelerin COVİD-19 pandemisi öncesi ve sürecinde kullandıkları GETAT yöntemlerini belirlemeye yönelik sorulardan oluşmaktadır. Verilerin tanımlayıcı analizleri yapılmıştır.

Bulgular: Çalışmada ebeveynlerin % 88.4’ü kadın ve %52’si üniversite mezunudur. Çocuklarının ise %38.4’ü 7-13 yaş arasında ve %51’i erkektir. Ailelerin çocukları için COVİD-19 pandemisi öncesi sağlığı korumak ve bağışıklığı güçlendirmek için GETAT yöntemleri kullananların oranı %38.9 iken COVİD-19 pandemisi sürecinde bu oranın %92.5 olduğu belirlenmiştir. Ailelerin bu süreçte çocukları için %99.9’unun bağışıklık sitemini güçlendirici, balık yağı ve vitamin içeren ilaçlar kullandığı saptanmıştır. Ayrıca ailelerin %31.8’inin sirke, %31.5’inin bal ve ürünlerini ve %24.5’inin ıhlamur gibi bazı besin ve bitkileri kullandıkları görülmüştür.

Sonuç: Ailelerin COVİD-19 pandemisi sürecinde GETAT yöntemlerini daha sık kullandıkları belirlenmiştir. Ayrıca ailelerin çocukları için bazı besin ve bitkilerden oluşan GETAT yöntemlerine başvurdukları görülmüştür. Sağlık ekibinin ailelere COVİD-19 pandemisi sürecinde çocuklarının sağlığı korumak ve geliştirme konusunda teknolojik araçlar yolu ile eğitim ve danışmanlık hizmeti sunmaları önerilmektedir.

Özet:

Amaç: Araştırmamız özel bir üniversitede sağlık hizmetleri meslek yüksekokulunda eğitim gören öğrencilerde Covid 19 korkusu ve yaşam kalitesini incelemek amacıyla gerçekleştirilmiştir.

Gereç ve yöntem: Araştırmaya ait veriler online ortamda oluşturulan formların öğrencilere mail veya mesaj yolu ile iletilerek doldurulması ile toplanmıştır. Veri toplama sürecinde araştırmacılar tarafından geliştirilen tanıtıcı bilgiler formu, Covid korkusu ölçeği ve SF-36 Yaşam Kalitesi ölçeği kullanılmıştır. İstatistiksel bulguların yorumlanmasında frekans tabloları ve tanımlayıcı istatistikler kullanılmıştır.

Sonuç ve öneriler: Covid 19 korkusu ölçeği puanı azaldıkça, yaşam kalitesi ölçeği alt boyutlarından emosyonel rol güçlüğü, ruhsal sağlık, sosyal işlevsellik, ağrı ve genel sağlık algısı ölçeği puanları artmaktadır. Covid 19 pandemi sürecinde beslenmelerinin düzensiz olduğunu ifade edenlerin sayısının yarıdan fazla olduğu belirlenmiştir. Ayrıca Covid 19 pandemi sürecinde öğrencilerin yarısından fazlasının uykularının düzensiz olduğunu ifade ettikleri belirlenmiştir. Bu nedenle Covid 19 pandemi sürecinde yaşanan korkunun, ruhsal sorunların ve yaşam tarzındaki değişikliklerin iyi yönetilememesinin beslenme alışkanlıklarında bozulma, uyku kalitesi ve yaşam kalitesinde azalmaya neden olduğu belirlenmiş olup, sürecin ilerleyen dönemlerde holistik bir bakış açısıyla özellikle genç popülasyonda rehabilite edilmesi önerilmiştir.

The paper proposes an original approach for predicting the values of the spatial series. This approach can be used, in particular, to recover missing data. The counter-prediction method was tested on a model of an artificial neural network (ANN), which is sequentially trained on the values preceding the predicted segment of the series on the left and right. The final prediction of the model is the weighted average of the results of these two sets. We have tested the work of the method using the example of predicting the dust content in the snow cover. 256 snow samples were taken with a step of 0.2 m along the line in the area of the dumps of the existing open pit for the extraction of copper ore. To check the accuracy of the models, based on the data obtained, two spatial series were created: a series of measured values (measured values as they are) and a mixed series (randomly mixed values of a series of measured values). The forecast with the minimum errors and the maximum correlation coefficient was obtained for a number of measured values. The least accurate forecast was obtained for a mixed series. RMSE for a series of measured values was 58% less than RMSE for a mixed series, an average value of the correlation coefficient was 0.3 for a series of measured values and -0.06 for a mixed series.

Published: April 2022

The purpose of this paper is to investigate the role of social media in firm generated content (FGC) and user generated content (UGC) which bring impacts on perceived value and two types of intention, namely the intention to follow on social media and the intention to enrol in vocational colleges. Online survey was applied to collect the data from 452 respondents. The hypotheses were tested empirically using a variance-based structural equation model. The results point out that FGC and UGC are positively and significantly influential towards value. Perceived value discovered is influential significantly towards the consumers’ intention to follow social media, while UGC holds the highest importance compared to other constructs. Those results manifest the role of marketing in social media in which it will eventually influence the intention to follow on social media and to enrol in vocational colleges. These will give the inputs to the institutions to arrange social media contents which are able to increase the intention to follow in which it also boosts the intention to enrol. This research also adds the existing knowledge about the role of social media towards the intention to enrol.

Micro-credit was designed to organize poor people's tiny savings into funds that could be accessed by the poor, particularly rural women. Microfinance is a powerful technique for affecting the socio-economic condition of respondents and their family members to generate more cash for personal purposes. The additional money enables the respondents' families to purchase nutritious food, land, and construction houses, have access to contemporary health care, multiple cultivations, and small business, and send their children abroad as well as to school. The objective of this study is to explore the reasons for the received microcredit and the impact of microfinance on socio-economic enrichment based on primary and secondary data by using previous studies and direct personal interviews, in-depth interviews through open-ended questionnaires conducted with microcredit receivers from BRAC, Grameen Bank, and ASA as well as field staff respectively at Balunnaghar in Cumilla, Bangladesh in 2021. Both random and Snowball sampling technique was adopted to select respondents. This study highlighted that microfinance has brought a lot of positive changes in respondents' income, family status, and overall socio-economic condition but somewhere few borrowers were unable to mobilize the credit appropriately; therefore, some bad loans arise. So, some recommendations are given for reducing the misuse of loans and also to be self-reliant.
