Dünya üzerinde internet ve sosyal medya kullanımı gün geçtikçe artmaktadır. Türkiye internet ve sosyal medya kullanımı açısından dünyada üst sıralarda yer almaktadır. Bu durumun doğal bir sonucu olarak günümüzde internet üzerinden yapılan pazarlama faaliyetlerinin ve sosyal medya aracılığıyla yapılan reklamların önemi arttırmıştır. COVID-19 salgını dolayısıyla yaşanan karantina ve kısıtlamalar da sosyal medya aracılığıyla internet üzerinden yapılan reklamların oranını ve önemini arttırmıştır. İnternet üzerinden yapılan reklamların önemli bir parçasını sosyal medya etkileyicilerinin yapmış olduğu reklamlar oluşturmaktadır. Sosyal medya kullanıcıları arasından, belli bir oranın üzerinde takipçiye sahip olan kişiler, herhangi bir eğitim ya da profesyonel şart aranmaksızın, sosyal medya etkileyicisi olarak reklam verenlerle yapmış oldukları anlaşmalar neticesinde sosyal medya paylaşımlarında markaların reklamını yapmaktadır. Sosyal medya etkileyicilerine yönelik ortaya çıkan en büyük kaygılardan biri tüketicileri sosyal medya paylaşımları vasıtasıyla belli ürün ve hizmetleri satın almaya kolaylıkla yönlendirebilmeleridir. Zira bu reklamların birçoğu reklam olduğu anlaşılmayacak şekilde samimi bir ürün veya hizmet önerisiymiş gibi takipçilere yani tüketiciye sunulmaktadır. Çalışmamızda, öncelikle sosyal medya etkileyicilerinin genel bir tanımını yapılarak devamında bu kişilerin sosyal medyada yapmış oldukları paylaşımların reklam içermesi durumunda bu reklamların hukuki mahiyeti analiz edilecektir. Özellikle yanıltıcı-aldatıcı ve örtülü reklam yasağını ihlal ederek sosyal medya yoluyla yapılan reklamlar karşısında Türk hukukunda ve karşılaştırmalı hukukta tüketicinin nasıl korunduğu değerlendirilecek ve bu reklamların haksız rekabet hukukundaki yeri analiz edilecektir. 5 Mayıs 2021 tarihinde Ticaret Bakanlığı tarafından yayınlanan Sosyal Medya Etkileyicileri Tarafından Yapılan Ticari Reklam ve Haksız Ticari Uygulamalar Hakkında Kılavuz da ayrıca analiz edilecektir. Çalışmamızın son kısmında Türk hukukunda sosyal medya etkileyicilerinin yapmış oldukları reklamlara ilişkin mevcut düzenlemeler değerlendirilerek bu düzenlemelere ilişkin önerilerimiz sunulacaktır.

REGIONALIZATION OF INPUT-OUTPUT TABLESAND AS A NECESSARY ELEMENT OF ANALYSIS AND FORECASTING OF THE MODEL
Authors: Ershov Yury S. , Ibragimov Naimdzhon M. , Dushenin Aleksandr I.
Published: October 2021

The main problems of constructing models used to develop of spatial and sectoral long-term economic forecasts are due to the lack of direct statistical data in full, i.e. regional tables of distribution of goods and services. Their calculation has to be carried out on the basis of a limited set of direct and indirect indicators that make it possible to determine the spatial structures of production, consumption, accumulation of fixed capital, etc. with an accuracy sufficient for further use in the information content of interregional intersectoral models. The report examines the problems of spatial allocation of the all-Russian table “input-output” and proposes the author's approach to the partial automation of the procedures necessary to construct a set of regional tables (by federal district). Regionalization was carried out using a static interregional intersectoral model with control of bordering outcomes. The result is a set of consistent regional tables as of 2015 - the sum of eight input-output tables exactly matches the all-Russian table. The constructed static multiregional input-output model (OMIOM) across federal districts is necessary for the next stage of work - the development of a semi-dynamic model used to calculate options for long-term national economic forecasts.

Authors: Kazantsev Kirill Y.
Published: October 2021

Increasingly complex business processes and rapidly changing market conditions force employers to invest more and more resources in human resources development. At the same time, it is not just the professional knowledge and skills of a particular employee that come first, but also their ability to adapt to changing market circumstances. Most Russian higher education institutions are focused on transferring to future specialists a structured system of knowledge and skills that fit into the concept of "hard skills"(skills that can be easily taught and the result of training can be measured), but the current market situation increasingly requires the development of "soft skills" - universal competencies that are difficult to quantify (ability to work in a team, balance, engagement, dedication), but which significantly affect the final result of the employee's work and the formation of competitive advantages of the entire enterprise. These skills contribute not only to personal professional growth, but also to improving the stability of the enterprise management system as a whole. Today, these areas of knowledge are more covered in the field of corporate education. The article considers the prerequisites for the development of the corporate education market, analyzes the existing models of building a system of professional knowledge and considers the role of professional imprinting in the training of specialists.

Published: October 2021

The Government of the Krasnoyarsk Territory has adopted a Forest Sector Development Strategy until 2030. Harvesting up to 36 million m of wood per yearis planned according to the strategy. About 20 million m3 per year should be procured in the Lower Angara region.At present, there is no verifiable information of economically available wood resources. The method for calculating the annual allowable cutacting for more than 100 years has disproved due to unrealistic forest management standards. The normal forest modellaid down in the method has not been implemented anywhere.The forest fund is federally ownedso it is the state instead of the region authority should provide up-to-date reliable information of forests to makesuccessful management decisions and developing strategic planning documents. A principle of effective forestry as production industry will be an objective market ecological and economic assessment of forest resourcesthat could be provided by the re-emerged forest inventory. Implementation of purposedcapital investment projects in the Lower Angara region will be difficult due to uncertainty of providing with wood resources required. Organization of forest use should be more flexible and promote both development of the forest sector and maintenance of the biosphere role of forests.

Risk-oriented economic control and supervisory activity (CND) consists in the fact that the objects of the economy under the supervision and control of the state are differentiated by the degree of probability of causing harm to human life and health, as well as material damage to the environment. The reform of the legislation affected the existing system of the CND, including the procedure for implementing the CND. Thus, the priority in conducting the CND is directed towards preventive measures to prevent violations and provide guarantees to economic entities in interaction with employees of executive authorities. The existing methodology for assessing the effectiveness of the activities of executive authorities, the main purpose of which is to assess the effectiveness of the activities of executive authorities in terms of the effectiveness of budget spending, trends in indicators of living standards, socio-economic development of the region, as well as the degree of implementation of methods and principles of management at the level in the region. At the moment, there is a need to develop indicators that characterize the effectiveness of a particular executive authority, including in the field of ensuring technosphere security. To select the indicators that characterize the effectiveness of the activity, first of all, it is necessary to select the goals that the activities of the executive authority are aimed at achieving.
EXPERIENCE OF USING THE RESOURCE APPROACH IN THE MANAGEMENT OF SOLID MUNICIPAL WASTE ON THE EXAMPLE OF THE SUBJECT OF THE RUSSIAN FEDERATION
Authors: Petrova Natalya Vl. , Usikova Oksana Vl. , Fedorova Alena V.
Published: October 2021

The growing resource consumption every year led to an increase in the volume of waste generated, which in turn led to a reduction in the area of land resources suitable for their burial and gave rise to the problem of effective disposal and recycling of waste. In this situation, human society needs to direct its development in a safer direction from an environmental point of view and revise the existing models of production and consumption. In tackling this problem, municipal solid waste can become a key link in a chain of interrelated factors, which must be considered together with other global issues such as the rational use of natural resources. Since municipal solid waste is a rich source of secondary resources, it is a “free” energy carrier, due to the fact that garbage - a renewable carbonaceous raw material that is currently used in the most inefficient way - is subject to landfill. In addition to the lost benefit, the state incurs additional financial losses associated with cleaning up waste-contaminated areas. In this regard, the article proposes approbation of the resource approach in waste management using the example of the Novosibirsk region.

The assessment and assurance of the quality attributes of dates is a key factor in increasing the competitiveness and consumer acceptance of this fruit. The increasing demand for date fruits requires a rapid and automated method for monitoring and analyzing the quality attributes of date fruits to replace the conventional methods used by inspection which limits the production and involves human errors. Moisture content (MC), dry matter content (DMC), and firmness (F) are three important quality attributes for two date cultivars (Khalas and Sukkari) that have been inspected using the hyperspectral imaging (HSI) technique based on the reflectance mode. Images of intact date fruits at the maturity stage Tamr were obtained within the wavelength range of 950–1750 nm. Monitoring and assessment of MC, DMC, and F [first maximum rupture force (MF, N)] were performed using a partial least squares regression model. Accurate prediction models were attained. The results highlight that the coefficients of determination (R2Prediction) are estimated to be 0.91 and 0.89 for MC, DMC, and F (N) with the lowest values of the standard error of prediction (SEP) equal to 0.82, 0.81 (%), and 4.12 (N), respectively, and the residual predictive deviation (RPD) values were 3.65, 3.69, and 3.42 for MC, DMC, and F (N), respectively. The results obtained from this preliminary study indicate the great potential of applying HSI for the assessment of physical, chemical, and sensory quality attributes of date fruits overall in the five maturity stages.

In recent years, neural stem cell transplantation has received widespread attention as a new treatment method for supplementing specific cells damaged by disease, such as neurodegenerative diseases. A number of studies have proved that the transplantation of neural stem cells in multiple organs has an important therapeutic effect on activation and regeneration of cells, and restore damaged neurons. This article describes the methods for inducing the differentiation of endogenous and exogenous stem cells, the implantation operation and regulation of exogenous stem cells after implanted into the inner ear, and it elaborates the relevant signal pathways of stem cells in the inner ear, as well as the clinical application of various new materials. At present, stem cell therapy still has limitations, but the role of this technology in the treatment of hearing diseases has been widely recognized. With the development of related research, stem cell therapy will play a greater role in the treatment of diseases related to the inner ear.
Crustal Anisotropy Beneath the Trans-North China Orogen and its Adjacent Areas From Receiver Functions
Authors: Xu Xiaoming , Ding Zhifeng , Li Li , Niu Fenglin
Published: October 2021

As an important segment of the North China Craton, the Trans-North China Orogen (TNCO) has experienced strong tectonic deformation and magmatic activities since the Cenozoic and is characterized by significant seismicity. To understand the mechanism of the crustal deformation and seismic hazards, we determined the crustal thickness (H), Vp/Vs ratio (κ) and crustal anisotropy (the fast polarization direction φ and splitting time τ) beneath the TNCO and its adjacent areas by analyzing receiver function data recorded by a dense seismic array. The (H, κ) and (φ, τ) at a total of 309 stations were measured, respectively. The Moho depth varies from ∼30 km beneath the western margin of the Bohai bay basin to the maximum value of ∼48 km beneath the northern Lüliang Mountain, which shows the positive and negative correlations with the elevation and the Bouguer anomaly. The average φ is roughly parallel to the strikes of the faults, grabens and Mountains in this study area, whereas a rotating distribution is shown around the Datong-Hannuoba volcanic regions. Based on the φ measured from the Moho Ps and SKS/SKKS phases, we propose that the crustal deformation and seismic hazards beneath the TNCO could be due to the counterclockwise rotation of the Ordos block driven by the far-field effects of the India-Eurasian collision.

Methods

In this retrospective cohort study, 2,192 patients who had undergone blastocyst FET treatment with natural cycles from October 2014 to September 2017 were included. Using propensity score matching, 177 patients diagnosed with LUF (LUF group) were matched with 354 ovulating patients (ovulation group). The LUF group was further stratified by the average LH peak level of 30 IU/L. Clinical pregnancy rate and live birth rate were retrospectively analyzed between the LUF and ovulation groups, as well as between LUF subgroups.

Results

After propensity score matching, general characteristics were similar in the LUF and ovulation groups. Clinical pregnancy rate in the LUF group was significantly lower than that in the ovulation group (47.46 vs. 58.76%, respectively, adjusted P = 0.01, OR 0.60, 95% CI 0.42–0.87). However, no significant difference was detected in live birth rate, although it was lower in the LUF group (43.50 vs. 50.00%, adjusted P = 0.19, OR 0.76, 95% CI 0.51–1.14). In the LUF subgroup analysis, both clinical pregnancy rate (43.02 vs. 62.30%, adjusted P = 0.02, OR 0.45, 95% CI 0.23–0.87) and live birth rate (37.21 vs. 59.02%, adjusted P = 0.01, OR 0.40, 95% CI 0.20–0.78) in the LH <30 IU/L subgroup were significantly lower than those in the LH ≥30 IU/L subgroup.

Conclusion

LUF negatively affected clinical outcomes of frozen/thawed embryo transfer of blastocysts, particularly when the LH surge was inadequate.

Marine clam is one of the main sources of arsenic (As), and the tidal flats of Jiangsu Province are considered major culturing areas for clams in mid-eastern China. In view of increasingly severe pollution in this region, concerns have been raised by the consumers with the safety of clams they purchased or may purchase. To address these concerns, we conducted a multi-year survey to determine the levels of As and As species in five major clam species cultivated in eight production areas of this region. Based on the above analysis data, Bayesian statistics used a Markov Chain Monte Carlo approach was applied to predict the toxic As residue distributions in clams produced in this region and their health risks to Chinese adults. It was found that the bioaccumulation ability of total As (tAs) and inorganic As (iAs) was species-specific, while Mactra veneriformis (MV) had the strongest accumulation capacity for toxic iAs (0.22–2.85 mg/kg dw). Up to 6.7% of the tested MV samples exceeding the iAs limit of China Food and Drug Administration. The content of iAs was also found to be related significantly to the harvest seasons, with clam in the spawning period (June) having the lowest iAs concentrations. The non-carcinogenic and carcinogenic health risk from dietary exposure to iAs associated with MV consumption was rather high, which suggested that specific attention should be paid to the safety of clam consumption in this region.

As the outermost layer of stems and branches, bark is exposed to the influence of atmospheric conditions, i.e., to changes in the air’s relative humidity and wetting during storms. The bark is involved in water interception by tree canopies and stemflow generation, but bark–water relations are often overlooked in ecohydrological research and insufficiently understood. Relative to other canopy ecohydrological processes, little is known about vertical variation in bark properties and their effect on bark hydrology. Thus, the objective of this study was to analyze changes in physical properties (thickness, outer to total bark thickness ratio, density, and porosity) and hydrology (bark absorbability, bark water storage capacity, and hygroscopicity) vertically along stems of Norway spruce [Picea abies (L.) Karst.] and silver fir (Abies alba Mill.) trees. Our null hypotheses were that bark hydrology is constant both with tree height and across measured physical bark properties. We found that bark thickness and the ratio of outer-to-total bark thickness decreased with tree height for both species, and this was accompanied by an increase in the bark water storage capacity. In contrast, the bark’s density, porosity, and hygroscopicity remained relatively constant along stems. These results inform ecohydrological theory on water storage capacity, stemflow initiation, and the connection between the canopy water balance and organisms that colonize bark surfaces.

Significant genetic association exists between rheumatoid arthritis (RA) and cardiovascular disease. The associated mechanisms include common inflammatory mediators, changes in lipoprotein composition and function, immune responses, etc. However, the causality of RA and vascular/heart problems remains unknown. Herein, we performed Mendelian randomization (MR) analysis using a large-scale RA genome-wide association study (GWAS) dataset (462,933 cases and 457,732 controls) and six cardio-cerebrovascular disease GWAS datasets, including age angina (461,880 cases and 447,052 controls), hypertension (461,880 cases and 337,653 controls), age heart attack (10,693 cases and 451,187 controls), abnormalities of heartbeat (461,880 cases and 361,194 controls), stroke (7,055 cases and 454,825 controls), and coronary heart disease (361,194 cases and 351,037 controls) from United Kingdom biobank. We further carried out heterogeneity and sensitivity analyses. We confirmed the causality of RA with age angina (OR = 1.17, 95% CI: 1.04–1.33, p = 1.07E−02), hypertension (OR = 1.45, 95% CI: 1.20–1.75, p = 9.64E−05), age heart attack (OR = 1.15, 95% CI: 1.05–1.26, p = 3.56E−03), abnormalities of heartbeat (OR = 1.07, 95% CI: 1.01–1.12, p = 1.49E−02), stroke (OR = 1.06, 95% CI: 1.01–1.12, p = 2.79E−02), and coronary heart disease (OR = 1.19, 95% CI: 1.01–1.39, p = 3.33E−02), contributing to the understanding of the overlapping genetic mechanisms and therapeutic approaches between RA and cardiovascular disease.
The Feasibility of Using Coxiella burnetii Avirulent Nine Mile Phase II Viable Bacteria as a Live Attenuated Vaccine Against Q fever

Published: October 2021

This study aimed to explore if viable C. burnetii avirulent Nine Mile phase II (NMII) can elicit protective immunity against virulent NM phase I (NMI) infection. Interestingly, mice immunized with viable NMII elicited significant protection against NMI infection at different time points post-immunization. Viable NMII induced a dose-dependent NMI-specific IgG response in mice, but all doses of NMII-immunized mice conferred a similar level of protection. Comparing different routes of immunization indicated that intranasally immunized mice showed significantly higher levels of protection than other immunization routes. The observation that viable NMII induced a similar level of long-term protection against NMI challenge as the formalin-inactivated NMI vaccine (PIV) suggests that viable NMII bacteria can induce a similar level of long-term protection against virulent NMI challenge as the PIV. Viable NMII also induced significant protection against challenge with virulent Priscilla and Scurry strains, suggesting that viable NMII can elicit broad protection. Immune sera and splenocytes from viable NMII-immunized mice are protective against NMI infection, but immune serum-receiving mice did not control NMI replication. Additionally, viable NMII conferred a comparable level of protection in wild-type, CD4+ T cell-deficient, and CD8+ T cell-deficient mice, and partial protection in B cell-deficient mice. However, NMII-immunized T cell-deficient mice were unable to prevent C. burnetii replication. Thus, both B cells and T cells are required for viable NMII-induced protective immunity but T cells may play a critical role. Collectively, this study demonstrates the feasibility of using avirulent NMII as a live attenuated vaccine against human Q fever.

Robotic devices are being employed in more and more sectors to enhance, streamline, and augment the outcomes of a wide variety of human activities. Wearable robots arise indeed as of-vital-importance tools for telerehabilitation or home assistance targeting people affected by motor disabilities. In particular, the field of “Robotics for Medicine and Healthcare” is attracting growing interest. The development of such devices is a primarily addressed topic since the increasing number of people in need of rehabilitation or assistive therapies (due to population aging) growingly weighs on the healthcare systems of the nation. Besides, the necessity to move to clinics represents an additional logistic burden for patients and their families. Among the various body parts, the hand is specially investigated since it most ensures the independence of an individual, and thus, the restoration of its dexterity is considered a high priority. In this study, the authors present the development of a fully wearable, portable, and tailor-made hand exoskeleton designed for both home assistance and telerehabilitation. Its purpose is either to assist patients during activities of daily living by running a real-time intention detection algorithm or to be used for remotely supervised or unsupervised rehabilitation sessions by performing exercises preset by therapists. Throughout the mechatronic design process, special attention has been paid to the complete wearability and comfort of the system to produce a user-friendly device capable of assisting people in their daily life or enabling recorded home rehabilitation sessions allowing the therapist to monitor the state evolution of the patient. Such a hand exoskeleton system has been designed, manufactured, and preliminarily tested on a subject affected by spinal muscular atrophy, and some results are reported at the end of the article.

Background: Relapsing–remitting multiple sclerosis (RRMS) is a subtype of degenerative inflammatory demyelinating disease of multifactorial origin that affects the central nervous system and leads to multifocal neurological impairment.

Objectives: To develop a clinical pathway (CP) for the management of Peruvian patients with RRMS.

Methods: First, we performed a literature review using Medline, Embase, Cochrane, ProQuest, and Science direct. Then, we structured the information as an ordered and logical series of five topics in a defined timeline: (1) How should MS be diagnosed? (2) How should a relapse be treated? (3) How should a DMT be initiated? (4) How should each DMT be used? and (5) How should the patients be followed?

Results: The personnel involved in the care of patients with RRMS can use a series of flowcharts and diagrams that summarize the topics in paper or electronic format.

Conclusions: We propose the first CP for RRMS in Peru that shows the essential steps for diagnosing, treating, and monitoring RRMS patients based on an evidence-based medicine method and local expert opinions. This CP will allow directing relevant clinical actions to strengthen the multidisciplinary management of RRMS in Peru.
