Published: April 2022

Abstract
Titanium dioxide (TiO2) has been regarded as a promising catalyst owing to its superior charge transport properties in photocatalytic degradation of organic pollutants and photocatalytic hydrogen generation. However, a major bottleneck toward the utilization of TiO2 photocatalysts is inefficient exploitation of visible light and low adsorption behavior. To address this issue, we fabricated a hybrid nanocomposite composed of one-dimensional N-doped TiO2 nanotubes (N-TNTs) and two-dimensional graphitic carbon nitride nanosheets (g-CNNs) to improve photocatalytic behavior. Furthermore, photogenerated electron–hole pairs in the hybrid N-TNT/g-CNN composites were efficiently separated by introducing g-CNNs. In addition, the improved specific surface area provided many active sites, resulting in higher photocatalytic reactions in kinetics. Based on these features, the Rhodamine B photocatalytic degradation efficiency was the highest, ∼85%, under solar-light irradiation in the N-TNT/g-CNN composites (7 wt% of the g-CNN content), which is two times higher than that of the N-TNT. Moreover, excellent durability and stability were observed after four cycles, which can be attributed to the extended optical absorption range and enhanced separation of the photogenerated electron–hole pairs.

Abstract
The electrochemical reduction of U(VI) and Re(VII) ions on Pt and Mo metals are discussed. The electrochemical behavior of U(VI) and Re(VII) in hydrochloric acid media was investigated using various electrochemical techniques. By analyzing the cyclic voltammogram of U(VI) and Re(VII) recorded on Pt electrode, a series of electrochemical reactions associated with uranium and rhenium were recognized, indicating that U(VI) and Re(VII) undergoes a single-step electron and multistep electron process under experimental conditions, respectively. The reduction of U(VI) and Re(VII) was found to be controlled by charge transfer and diffusion in hydrochloric acid media. The diffusion coefficient of U(VI) and Re(VII)was determined to be 4.22–5.99 × 10−6 cm2 s−1 and 1.50–2.90 × 10−5 cm2 s−1, respectively, and the activation energy for the diffusion are calculated to be 18.12 kJ mol−1 and 14.52 kJ mol−1 by cyclic voltammetry at different temperatures. The reduction process of U(VI) and Re(VII) at hydrochloric acid is further studied by potentiostatic electrolysis. It is feasible to realize the reduction of uranium and rhenium from aqueous solution by electrolysis.

Published: April 2022

Abstract
The Covid-19 pandemic has posed new challenges for occupational safety and health. The protection of disabled and other vulnerable employees (risk groups) is no exception. For these groups of employees, the special hazards and risks associated with the workplace must be given special consideration. This article presents our study of company practices for dealing with risk groups, with particular reference to remote working constellations, and shows that the involvement of employee representative bodies has a positive impact on the scope and quality of protective measures. However, the low level of involvement of employee representatives in the planning and implementation of protective measures is problematic. The results are from an online survey of 1543 representatives of works and staff councils and representatives of severely disabled people in Germany.

Nach fest kommt lose – zu komplex für Qualität?
Authors: Sommerhoff Benedikt 
Published: April 2022

Abstract
Billigst, schnellstmöglich, bestmöglich, das ist die pauschale Forderung der Märkte und der Kunden an Anbieter von Produkten. Diese Forderungen ziehen sich durch die gesamte Lieferkette. Die enormen Technologiesprünge und Innovationen der letzten Jahre haben uns hierfür neue Möglichkeiten verschafft. Sie haben aber auch die Erwartungshalten der Kunden geprägt: alles ist möglich, jetzt sofort. Gleichzeitig ist die Belastungsgrenze vieler Infrastrukturen erreicht oder sogar überschritten. Schon kleine Störungen eskalieren zu Produktfehlern, Prozess- oder Lieferkettenunterbrechungen, erst recht die großen durch Wetterextreme, Kriege, Sanktionen und Ressourcenknappheit. Längst brechen in vielen Branchen Verfügbarkeit und Qualität von Produkten ein. Die Produktionsstätten können durch ihren Anteil an der Qualitätssicherung die durch zu viel Komplexität entstehenden Qualitätseinbrüche nicht mehr kompensieren. Wir brauchen dringend Konzepte für die Reduktion dieser Komplexität.
Annual STI Testing Among Sexually Active Adolescents
Authors: Liddon Nicole , Pampati Sanjana , Dunville Richard , Kilmer Greta , Steiner Riley J 
Published: April 2022

OBJECTIVES
National guidelines call for annual testing for certain sexually transmitted infections (STIs) among specific adolescent populations, yet we have limited population-based data on STI testing prevalence among adolescents. With inclusion of a new item in the 2019 national Youth Risk Behavior Survey, we provide generalizable estimates of annual STI testing among sexually active high school students.

METHODS
We report weighted prevalence estimates of STI testing (other than HIV) in the past 12 months among sexually active students (n = 2501) and bivariate associations between testing and demographic characteristics (sex, age, race and ethnicity, sexual identity, and sex of sexual contact). Multivariable models stratified by sex and adjusted for demographics examine the relationships between testing and sexual behaviors (age of initiation, number of sex partners, condom nonuse at last sexual intercourse, and substance use at last sexual intercourse).

RESULTS
One-fifth (20.4%) of sexually active high school students reported testing for an STI in the previous year. A significantly higher proportion of female (26.1%) than male (13.7%) students reported testing. Among female students, prevalence differed by age (≤15 years = 12.6%, age 16 = 22.8%, age 17 = 28.5%, or ≥18 years = 36.9%). For male students, there were no differences by demographic characteristics, including sexual identity, but most sexual risk behaviors were associated with increased likelihood of STI testing (adjusted prevalence ratios ranging from 1.48 to 2.47).

CONCLUSIONS
Low prevalence of STI testing suggests suboptimal adherence to national guidelines, particularly for sexually active adolescent females and young men who have sex with men who should be tested for Chlamydia and gonorrhea annually.

The subgenus Boophthora is a typical Palearctic taxon, which includes only 6 species, among them. Simulium erythrocephalum has a transpalearctic distribution. In Europe, Adler notes only the species S. erythrocephalum, and Yankovsky – two species S. (Boophthora) erythrocephalum and S. (Boophthora) chelevini. According to morphological characteristics, these species differ in their life stages. We have studied the development of S. erythrocephalum and S. chelevini from three rivers of Volyn region, Ukraine (Styr, Chornoguzka, Putylivka) from 2017 to 2019. We used the EPPO PM7 / 129 standard. Collected samples, 615-bp fragments of the COI gene were sequenced from five individuals of S. erythrocephalum and five individuals of S. chelevini and compared with four samples of S. erythrocephalum from the GenBank. We obtained the nucleotide sequence of S. chelevini. All of the S. erythrocephalum samples from Ukraine had 692 bases, the S. erythrocephalum samples from Armenia had 673 bases. S. erythrocephalum and S. chelevini did not have any intraspecific variations. These intraspecific variations were not larger than the interspecific variations. It has been proved that the populations of S. erythrocephalum and S. chelevini from medium and small rivers of Volyn do not differ in biological, behavioural and genetic characteristics. Comparison of S. erythrocephalum and S. chelevini life stages showed clear differences in 20 morphological features, which are probably manifestations of phenotypic variability. Comparison of species with data from the GenBank from Spain and Armenia on the mitochondrial cytochrome c oxidase subunit I (COI) gene confirmed the opinion that S. erythrocephalum and S. chelevini are one species. On the phylogenetic tree, the data are not grouped, there is no clear separation of the clades. Bootstrap values are 95–100%, which may indicate a significant similarity of all studied samples and the lack of isolation of individual morphotypes from Volyn, Spain and Armenia. To finally confirm the taxonomic position of these two species, additional research is needed covering more individuals from different parts of Europe and analysis of more genes.

Published: April 2022

Purpose: This study focuses on identifying aspects that can influence the behavior of consumers who make purchases at thematic cafes in Malang. This study uses a thematic store atmosphere as an independent variable, impulse buying behavior as a dependent variable, as well as positive emotion and impulse buying tendency as mediating variables.
Design / Method / Approach: Quantitative approaches and explanatory research are used in this study. The respondents in this study were consumers who had visited the thematic cafe in Malang city, and a purposive sampling technique with a total sample of 200 respondents was used to determine the number of samples. The data collection method used a questionnaire, and the data were analyzed by PLS-SEM.
Findings: The findings of this study indicate that the thematic store atmosphere does not have a significant effect on impulse buying behavior. Meanwhile, positive emotion and impulse buying tendency were able to perfectly mediate the relationship between the thematic store atmosphere and impulse buying behavior.
Practical Implications: A thematic cafe with an atmosphere designed according to the concept of a theme that is carried out very well can produce feelings of pleasure, excitement or comfort so that consumers feel like exploring or enjoying the atmosphere of the cafe so as to encourage unplanned purchases.
Originality / Value: The thematic store atmosphere is based on the thematic cafe trend in the city of Malang. The researcher also tries to make this research more comprehensive by examining the relationship between an impulse buying tendency and positive emotion both of which are mediating variables.

Published: April 2022

Abstract
The village today is only partially what we used to know of in the past, our previous image rooted in a sinking world, nothing but memories. In the 21st century, even in rural communities, the daily routine, practices and strategies of economic life are determined by the processes of modernization and globalization, in conjunction with information and communication technologies along with the wide-ranging proliferation of digital devices. It can be said that life in the 21st century village also shows a simultaneous constraint of modernization (the constraint of evolution and change) and the presence of masses incapable of changing (even if their number is continuously decreasing). The coexistence and confrontation of these opposing forces and ideologies characterizes the Hungarian/Transylvanian rural space in Romania during the 21st century. All these have led to the degradation of previous community patterns, resulting in the faltering position of tradition as well as a major change in the role it plays in the life of said communities.
Development of the combined approach to the valuation of intellectual property objects
Authors: Svishchova Nataliia 
Published: April 2022

The object of this research is a combined approach to the valuation of intellectual property. The paper compares the traditional approaches to valuation: profitable, market and cost, and identified the shortcomings of each. During the work the methods of analysis and synthesis of scientific literature were used to highlight the disadvantages and advantages of traditional approaches, statistical and comparative methods for estimating the value of patents in one industry. Mathematical modeling was also used to develop the formula of the combined approach. Researchers raised the issue of determining the pricing factors that are taken into account when determining the calculation parameters and dependent coefficients of adjustment of the value of intellectual property. Researchers presented methodological recommendations for calculating the integrated coefficient of influence of qualitative and quantitative factors, taking into account the type of object and the features of standardized approaches to evaluation.
As a result of the analysis of approaches the improvement of the combined approach for definition of cost of object of intellectual property is offered. The development takes into account the purpose of the assessment and the availability of complete, reliable and objective information, as well as the affiliation of the intellectual property to a particular industry and the impact of technological development of this industry. On the basis of the proposed coefficients of adjustment of the value of intellectual property objects, the value of industrial property according to the patent of Ukraine UA85101 and some inventions of the power engineering industry of enterprises of Kharkiv region (Ukraine) was calculated. The best result for the patent owner of JSC «Ukrainian Energy Machines» are the calculations obtained on the basis of the combined approach, taking into account the traditional profit approach and the integrated coefficient. According to the studied model, the value of industrial property UA85101 is 26930 USD. These calculations assume the best economic effect of using the rights to this patent in the company, or obtaining income from the sale of a license for this patent using a lump sum or royalty. The practical applicability of the study allows industrial enterprises to assess the possibility of improving the efficiency of intellectual property management, which provides maximum benefit from the commercialization of innovations.
Is the Long-Term Probability of the Occurrence of Large Earthquakes along the Nankai Trough Inflated?—Scientific Review
Authors: Hashimoto Manabu 
Published: April 2022

Abstract
The Earthquake Research Committee (ERC), the Headquarters for Earthquake Research Promotion, Japan, issued a new report on long-term evaluation of the occurrence of large earthquakes along the Nankai trough, southwestern Japan, in 2013, which was made along the line of the revision of national earthquake counter measures according to the 2011 Great Eastern Japan Earthquake Disaster. The central issue was the 30-yr probability, but the method to estimate probability was not changed from the previous one issued in 2001 based on the time-predictable model, which led to a 60%–70% chance of M ≥ 8 event during the coming 30 yr. However, there are several drawbacks in this evaluation such as neglect of errors in uplift data, inconsistency between uplift rate and geodetic and geomorphological data, mechanical interpretation of time-predictable model, and contradiction between the assumptions in Brownian passage time model and time-predictable model. Because ERC calculates probability with average recurrence intervals for other subduction and active fault zones, the same scheme should be adopted to the Nankai trough.

Purpose. Analysis of the results of weakening of previously operated internal rectus muscle by the method of Z-shaped marginal myotomy.Patients and methods. The study included 87 children with an initially large-angle of strabismus. Children age — from 2 to 14 years (average age — 9.09 ± 0.78 years). The initial strabismus angle was from 30° to 60° according to Girschberg (average angle — 45.7° ± 2.3°). All children underwent a staged surgical treatment — recession of the internal rectus muscle and resection of the external rectus muscle in both eyes. The residual deviation angle after two stages of surgical treatment ranged from 6° to 10° (on average up to 9.1° ± 0.75°) according to Girschberg. All patients underwent a Z-shaped marginal myotomy on the operated internal rectus muscle. The follow-up period after surgery ranged from 1 year to 5 years.Results. A satisfactory anatomical result (orthotropy) was achieved in 91 % of cases (79 children), hypocorrection in 9 % of cases (8 children), hypercorrection — 0 %. In 8 patients with hypocorrection, after 6–8 months, the fourth stage of surgical treatment was performed with the method of Z-shaped marginal myotomy of the internal rectus muscle in the paired eye, after which orthotropy was achieved.Conclusion. An analysis of the surgical treatment results of operated esotropia have showed that the method of Z-shaped marginal myotomy makes it possible to weaken the tone of the previously operated internal rectus muscle with minimal trauma. Using the method of Z-shaped marginal myotomy in the treatment of residual-angle strabismus, orthotropy is achieved while preserving the biomechanics of the oculomotor muscles — the internal rectus muscle remains in the plane of its functional action. At initially large-angle of strabismus, conducting a Z-shaped marginal myotomy of the internal rectus muscle after stepwise surgical interventions on the horizontal rectus muscles of both eyes can be recommended as a modern, reliable and effective method of surgical treatment of residual-angle of strabismus, which allows to achieve the planned functional and cosmetic result.

Bloodstream infections (BSIs) remain a leading cause of morbidity and mortality especially in intensive care units across the world and timely appropriate antimicrobial therapy is a corner stone in its treatment (i) To compare the time difference to diagnose BSIs between FABCID2 and identification and sensitivity by automated systems (ii) To analyse the clinical utility of the FABCID2 panel in positive blood samples among ICU patients.This was a prospective study done from July 2020 to August 2020 where consecutive thirty positive blood culture received from ICUs were processed for gram stain, culture and antimicrobial susceptibility along with performing PCR with BioFire FilmArray Blood Culture Identification2 (FABCID2) Panel. Time line of positive blood culture from receipt to report generation at multiple points were captured along with impact of results in terms of changing antimicrobial therapy of the patients and outcome. : A total of 38 microorganisms were identified from 30 patients. In 70% (21/30) of patients, the result of FABCID2 and growth in culture matched completely, in 23% (7/30) they matched partially and in 6% they did not match. The match between genotypic markers in the assay and phenotypic susceptibility was 100%. FABCID 2 results prompted clinicians to change the antimicrobials prescribed to 33% of total patients (escalation was done in 23.3% of patients and de-escalation was done in 10%. Clinical utility of the FABCID2 Panel in Identification of microorganisms and resistance markers from Positive Blood Culture Bottles is significant which should be used in conjunction with conventional methods to impact patient outcome and antimicrobial stewardship program.
