Authors: Raharjo Wijang Wisnu , Kusharjanto Bambang , Triyono Teguh
Published: March 2021

In this study, an environmentally friendly composite was prepared from cantala fiber and recycled high-density polyethylene. Alkali treatment was utilized to improve the fiber–matrix interface of cantala fiber. The alkali treatment was carried out with a 2% NaOH solution for periods of 0, 4, 8, 12, 16, 20, and 24 hours. Various recycled high-density polyethylene composites reinforced with treated and untreated short cantala fiber were produced by hot press. The tensile and impact properties of the composites were examined to reveal the effect of alkali treatment. Changes in fiber–matrix bonding were investigated via composite fractography using scanning electron microscopy. A study of fiber morphology and other supporting tests, such as the fiber tensile test, X-ray diffraction, and Fourier transform infrared microscopy were also carried out. The results show that the addition of alkali-treated fiber to recycled high-density polyethylene composites enhanced the composites’ tensile and impact performance: Tensile strength improved by 15.5% and impact strength by 24.8%.

Published: March 2021

This study aims to investigate the effect of servant leadership on organizational citizenship behavior and knowledge-sharing behavior. It further explores servant leadership for its potential mediation of work engagement and moderation of self-efficacy in organizational citizenship behavior and knowledge-sharing behavior. Time-lagged data was collected from 264 respondents from Pakistan’s banking sector via convenience sampling. The relationships between servant leadership and organizational citizenship behavior, servant leadership and knowledge-sharing behavior were analyzed through partial least squares structural equation modeling. The results of this analysis reveals that the effect of servant leadership on organizational citizenship behavior and knowledge-sharing behavior is significant in that work engagement acts as a mediator, and follower’s self-efficacy plays the role of moderator. Based upon social exchange theory, the study supports that servant leadership increases citizenship and knowledge-sharing behavior. In addition, the study provides an understanding of how servant leadership mediates work engagement for pragmatic synergetic outcomes in a Pakistani context. The study’s implications and limitations are also discussed, and suggestions for future research are noted.
Media as an Influencer of Societal Behavior, Case of COVID-19
Authors: Singer Nermeen
Published: March 2021

Coronavirus COVID-19 is, without a doubt, the number one international news event in 2020. The purpose of the study is to prove that the media are having a detrimental effect on the psyche and behavior of the individual by means of spreading panic within society. This study demonstrates the relationship between the information presented in the media and the reaction of the people towards it. The methodology includes the use of an online questionnaire for gathering raw data. Descriptive statistics and the ANOVA statistical analysis will further be conducted in determining the poor reaction of the individual and the spread of mass hysteria/panic by the media in the information field. People are yet disinclined to agree to the fact that the media is influencing their behavior, especially in times of crisis. And even though their responses evidently suggest that their will has been influenced by the information presented from the TV screen, not everyone has yet acknowledged the fact that TV and media propaganda is tampering with their thinking and behavior. Application of the study can further be used in a greater analysis determining the attitude of the people in various countries towards their media, and how the specific media influenced the behavior of the people changing their lives. No study in the field of media psychology has been conducted in relation to COVID-19 panic due to media propaganda.

Authors: Примин О.Г.
Published: March 2021

Рассмотрены вопросы надежности трубопроводов сетей водоснабжения и водоотведения городов и поселений России. Приведены соображения (в порядке дискуссии) о необходимости разработки и принятия Технического регламента о безопасности сетей водоснабжения и водоотведения централизованных систем водоснабжения и водоотведения. Технический регламент установит требования к сетям водоснабжения и водоотведения, обязательные для применения и исполнения на территории РФ. Отмечено, что в водной отрасли России в настоящее время отсутствует единая система, выработанная на основе практики применения обязательных требований к трубной продукции, используемой в сетях водоснабжения и водоотведения, и обязательной сертификации (декларирования). Предлагается область применения такого Технического регламента – сети централизованных систем холодного водоснабжения и водоотведения (канализации) на всех этапах их жизненного цикла, а также материалы и изделия, трубы, арматура, колодцы и связанные с ними процессы проектирования, строительства, эксплуатации, технического обслуживания, текущего и капитального ремонта, консервации и ликвидации сетей водоснабжения и водоотведения (канализации).

The issues of reliability of pipelines of water and sewer networks of Russian cities and settlements are considered. Considerations (by way of discussion) on the need for the development and adoption of Technical Regulations on the safety of water and sewer networks of public water supply and wastewater disposal systems are presented. The Technical Regulations will establish the requirements to water and sewer networks that will be mandatory for use and compliance on the territory of the Russian Federation. It is noted that the water industry in Russia is currently lacking a uniform system developed on the basis of the practice of applying mandatory requirements to pipe products used in water and sewer networks and their mandatory certification. The scope of application of such Technical Regulations is proposed, i. e. networks of public systems of cold water supply and wastewater disposal (sewerage) at all stages of their life cycle, as well as materials and articles, pipes, fittings, manholes and related processes of design, construction, operation, maintenance, current repairs and overhaul works, conservation and abandonment of water supply and sewer networks.

Published: March 2021

This paper reports on the memory characteristics of solution-processed organic phototransistors (OPTs) based on poly(3-hexylthiophene) with organic semiconductor floating gates and their application to image sensors. The addition of a small amount of soluble fullerene to the floating-gate layer enhances the erasing characteristics, which helps increase the on- and off-current ratio of the OPT memories. Furthermore, the OPT memories can achieve a long extrapolated retention time (>109 s) and high photosensitivity upon illumination of as weak as 10 μW cm‒2. A black and white pattern printed on paper can be imaged using the solution-processed OPT memory array.

We report on efficient terahertz (THz) wave generation of Fe/Pt diabolo-shaped spintronic antennas with different Pt thicknesses fabricated on MgO substrates. Compared with the antenna-free spintronic bilayer, ∼45% and ∼98% emission amplitude improvements were obtained when using the antennas with thin and thick Pt, respectively, as THz radiation sources. The improvement can be attributed to the enhanced outcoupling of THz radiation to free space and to the enhanced THz emission with the deposition of thicker Pt layer at the displacement current direction. Our results suggest that efficient spintronic radiation sources can be obtained with proper design of these THz emitters.

Authors: Momon  , Wati Lela Nurlaela , Sutar
Published: March 2021

In the face of business competition, a company strategy is needed by seeking and exploiting opportunities in the business environment, one of which is through political connections. Ownership structure plays an essential role in the company to determine the firm performance. The high concentration of family ownership has the power to reduce agency conflicts between management and stakeholders in a company. Concentrated ownership can serve as corporate governance mechanism for better and effective monitoring of management. This study was conducted to determine empirical evidence of the effect of political connections and family ownership structure on firm value. The sample in this study was 390 data of the manufacturing company. The data analysis used is moderating regression analysis. The results of this study are a positive influence of political connections and family ownership structure on firm value. The results showed that the more the company had a strong political connection and was controlled by the family, the more the firm value would increase. The interaction of political connections can strengthen the influence of family ownership on firm value. It proves that the family ownership structure plays a role in determining political connections in Indonesia, especially in manufacturing companies. The existence of empirical evidence that shows that the firm value controlled by a politically connected family is higher than companies that are not connected politically, which implies investors to invest in companies that are politically connected and companies controlled by families with majority ownership because it is proven to increase firm value.

Published: March 2021

As the fifth-generation (5G) mobile communication is utilizing millimeter-wave (mmWave) frequency bands, electromagnetic field (EMF) exposure emitted from a 5G mmWave mobile handset should be evaluated and compliant with the relevant EMF exposure limits in terms of peak spatial-average incident power density. In this work, a fast power density (PD) assessment method for a 5G mmWave mobile handset using the equivalent currents (EQC) method is proposed. The EQC method utilizes the intermediate-field (IF) data collected by a spherical measurement system to reconstruct the EQCs over a reconstruction surface, and then computes the PD in close proximity of the mobile handset with acceptable accuracy. The performance of the proposed method is evaluated using a mmWave mobile handset mock-up equipped with four quasi-Yagi antennas. The assessed PD results are compared with those computed using full-wave simulations and also those measured with a planar near-field (NF) scanning system. In addition, three influencing factors related to the accuracy of the EQC method, namely, the angular resolution, the phase error, and the handset position in the IF measurements, are also analyzed. The proposed method is a good candidate for fast PD assessment of EMF exposure compliance testing in the mmWave frequency range.
PERBANDINGAN PEMIKIRAN AHMAD TAFSIR DENGAN PAULO FREIRE MENGENAI FILSAFAT DAN ILMU PENDIDIKAN
Authors: Aziz Nurdin Abdul
Published: March 2021

Pendidikan merupakan panggilan ontologis manusia. Seseorang dari mulai berjalan, hingga dapat berbahasa, tak lepas dari pendidikan. Seiring berjalannya waktu, pendidikan disistematiskan, lalu mengkonsep dan merumuskan filsafat serta ilmu pendidikan. Dalam mengkonsep dan merumuskan filsafat serta ilmu pendidikan itulah terdapat perbedaan pendapat, hingga membentuk berbagai aliran dan ideologi. Ahmad Tafsir mengambil agama Islam sebagai dasar pemikirannya, sedang Paulo Freire mengambil pendidikan kritis. Tujuan penelitian ini adalah untuk mengetahui pamikiran Ahmad Tafsir dan Paulo Freire mengenai filsafat dan ilmu pendidikan. Aspek yang diambil dari filsafat dan ilmu pendidikannya adalah hakikat manusia, dasar pendidikan, tujuan pendidikan dan metode pendidikan. Lalu dibandingkan untuk mengetahui persamaan dan perbedaannya. Masing-masing aspek yang dibahas, mempunyai titik kesamaan dan perbedaan. Secara universal, persamaannya adalah memandang pendidikan bukan sekedar belajar angka dan teori, tetapi juga belajar tentang kehidupan. Maka, sebaik-baiknya pendidikan adalah yang mampu mengatasi jamannya. Perbedaannya terletak pada asumsi. Ahmad Tafsir mendasarkan pendidikannya pada ajaran agama Islam, sedang Paulo Freire mendasarkannya pada akal dan norma-norma kemanusiaan. Perbedaan asumsi itu dipacu oleh perbedaan lingkungan dan realitas sosial yang mereka hadapi.

Drugs injected intradermally spread slowly into the underlying tissues and produce a drug-saving effect. The Italian society of mesotherapy suggested that intradermal therapy obtains analgesic effect on localized pain, with a lower risk of systemic drug interactions. We report a case of post-herpetic pain successfully treated by this technique. This case confirms that the intradermal administration technique (mesotherapy), which is based on the pathophysiology of the disorder, according to the recommendations, can contribute to the management of patients who do not tolerate standard therapies.

Published: March 2021

Background: Various water-borne diseases have been seen in developed and developing countries, like  Coliform bacteria in food and drink due to their poor making.Objective: This study aims to estimate the hygiene factors and examine the content of Coliform bacteria and in Thai Tea drinks in Yogyakarta Municipality.Methods: A cross-sectional method was used in all Thai Tea product sellers in Yogyakarta Municipality from September to November 2020. A total of 30 sellers were included, and 30 different types of Thai Tea products were tested using the Most Probably Number (MPN) method at the Health and Calibration Laboratory Center, Yogyakarta, Indonesia. Descriptive statistics, Chi-square, and Fisher exact test were used for data analysis.Results: Laboratory tests showed half of Thai Tea products contaminated with Coliform bacteria more than MPN/100ML. Of all Thai Tea sellers, about 83.3% of them were never hygiene food sanitation training. Findings also show that the seller's hygiene sanitation was significantly associated with the existence of Coliform bacteria in Thai Tea (Crude OR=0.44, 95% CI=0.20-0.98). The sellers with poor sanitation facilities were four times more likely to have Coliform bacteria in their Thai Tea products (Crude OR=4.0, 95% CI=1.41-11.35). Meanwhile, hygiene food sanitation training and location of selling did not have a significant relationship with the presence of Coliform in Thai Tea.Conclusion: In sum, the existence of Coliform in Thai Tea drinks in the city of Yogyakarta is influenced by the hygiene sanitation and sanitation facility. Training on personal hygiene for each seller is necessary to obtain Thai Tea products that contain Coliform bacteria according to standards. This is very useful to do to reduce food-borne disease. This study was funded by Ahmad Dahlan University, Yogyakarta, Indonesia.
Vitamin D and chronic spontaneous urticaria: searching for algorithms of personalized therapy
Authors: Kukes Ilya V. , Borzova Elena Yu. , Nenasheva Natalya M. , Sychev Dmitriy A.
Published: March 2021

Today, we can see a great interest in vitamin D because it participates in the regulation of many metabolic processes, and its deficiency is associated with the development of various diseases. Chronic spontaneous urticaria (CSU) is the disease that affects the quality of patients life, and the existing strategy of patient management is not always sufficiently effective. Nowadays, there is enough information about the role of vitamin D deficiency and the severity of CSU. That is why it is important to study not only therapeutic schemes, but also a role of genetic variability that may have an impact on vitamin D levels.
Such studies will help to personalize the treatment schemes for patients with CSU. At the same time, the focus of these studies should be not only on the receptor and vitamin D binding protein, but also on P450 system, which plays a key role in the vitamin D metabolism.

Authors: Barycheva Liudmila Yu. , Dushina Liudmila V , Golubeva Marina V. , Minasyan Milana M. , Medvedenko Yulia N.
Published: March 2021

BACKGROUND: Allergen-specific immunotherapy (ASIT) helps to reduce spontaneous and to induce basophil reactivity, which is one of the major mechanisms of its effectiveness. A number of studies, though, have not confirmed the informative value of the basophil activation test (BAT), in case of ASIT, with house dust mites, meadow grass pollen, and wasp venom. BAT outcomes are likely to be influenced by the properties of the sensitizing allergen, the duration of ASIT, and the BAT markers that are used.
AIMS: To evaluate the basophils reactivity in the patients sensitized to weed pollen and treated with allergen-specific therapy.
MATERIALS AND METHODS: The study involved 60 patients (aged 1655) with allergic rhinitis sensitized to weed pollen. The diagnosis was based on the skin test outcomes as well as on identifying specific antibodies to major allergens of ragweed, wormwood, timothy, and birch. The pre-seasonal ASIT involved water-salted extracts of pollen allergens during 2 years. Clinical symptoms and the immunotherapy effectiveness were evaluated 6 and 18 months after the ASIT started. BATs were made before the treatment, after the first and second courses of pre-seasonal ASIT, which corresponded to zero, the 3rd and the 15th months of the treatment. The activated basophils were identified based on the CRTH2pos CD203brightCD3neg phenotype.
RESULTS: The first treatment course was completed by 52 patients, while the second one by 43 patients. A statistically significant decrease in spontaneous basophil reactivity was detected only after the second course of ASIT. The decrease in the allergen-induced basophil activation was identified in 67.4% of the samples obtained after the first ASIT course, and in 67.6% of samples taken after the second immunotherapy course. A decrease in the BAT stimulation index (BAT SI) was identified mainly in the patients featuring positive treatment outcomes.
CONCLUSIONS: ASIT influences on the basophil reactivity indicators in the patients sensitized to weed pollen. The basophil activation test may be considered as a potential predictor of ASIT effectiveness.

Published: March 2021

BACKGROUND: Biologicals use in severe asthma (SA) is associated with targeted therapy (TT) availability problem. Ensuring the availability of biologicals can be resolved within the territorial compulsory medical insurance program (TCMIP) in day-stay or round-the-clock hospital.
AIMS: This study aimed to develop and implement a program for immunobiological therapy (IBT) introduction for SA in Sverdlovsk Region (SR).
MATERIALS AND METHODS: Program for introduction of IBT for SA was developed in SR in 2018 to provide patients with expensive biologicals within the TCMIP. Program includes the following: SA prevalence study in SR; practitioners training in differential diagnosis of SA; organization of affordable therapy for patients with SA; registration of patients with SA сreation and maintenance; and selection and management of patients with SA in accordance with federal clinical guidelines.
RESULTS: Atopic phenotype in SA was detected in 5%, eosinophilic ― in 2.3% of all analyzed cases of asthma (n=216). Practitioners of SR were trained in differential diagnosis of SA. Orders of the Ministry of Health of SR were issued as follows: regulating the procedure for referring patients with SA to IBT, with a list of municipal medical organizations providing IBT in a day-stay or round-the-clock hospital; approving regional registration form of patients with SA requiring biologicals use; ungrouping of clinical and statistical groups of day-stay hospital was depending on INN and dosage of biologicals; and selecting patients with SA for TT and including them in the regional register. Initiating of TT in round-the-clock hospital and continuation therapy in day-stay hospital provides a significant savings in compulsory medical insurance funds.
CONCLUSIONS: IBT introduction for SA in SR is carried out within the framework of the developed program. Principle of decentralization brings highly specialized types of medical care closer to patients making it possible to provide routine medical care in allergology-immunology profile in the context of restrictions caused by coronavirus disease 2019 pandemic.

The article describes a retrospective analysis of the dynamics of energy and protein nutritional value of 555 samples of haylage from annual grasses selected in various agroclimatic zones of the Republic of Tatarstan in the period from 1993 to 2018. Studies have established a tendency for a slight decrease in the concentration of metabolizable energy in dry matter of haylage. The long-term average value of the level of exchange energy was 8,92 MJ/kg, which is 3,84% higher than the norm. The maximum content of exchangeable energy was established in 1996 (9,85 MJ/ kg). The minimum content was revealed in 2007 and amounted to 8,61 MJ/kg. The average long-term value of the concentration of net lactation energy in dry matter of haylage was 2,00 MJ/kg, which is 1,52% higher than the norm. The highest content of net energy of lactation was noted in 1996 and amounted to 3,14 MJ/kg, which is higher than the long-term average and the norm values by 57,00 and 59,39%, respectively. The lowest value was found in 2003, when the deviation from the norm was –27,23%. The content of digestible protein in 1 kg of dry matter of haylage from annual grasses tended to increase slightly. The average long-term value for this indicator was 89,19 g/kg, which is 20,74% higher than the norm. Only in 1996, the content of digestible protein was below the norm and amounted to 71,57 g/kg. The highest content was revealed in 2015 – 107,38 g/kg, which is 20,39 and 45,36% higher than the average long-term value and the value of the norm, respectively.
