Published: December 2022

Optimization of transport work is necessary in case of uncontrollable growth of the described costs. The process of optimizing transport costs at the enterprise begins with an analysis of the current logistics strategy and collection of recommendations for its correction. The following aspects of the transport system of the company are subject to analysis: the method of movement of goods; the choice of vehicle type and its specific model; the selection of the carrier company and other logistics intermediaries; the layout of the company’s storage terminals. An optimized transport system can reduce the cost of production and sales of products and increase staff efficiency.
There are three main directions in which innovations will ensure the reduction of costs for cargo and passenger transportation: the choice of optimal vehicles, the selection of optimally located unloading and loading points, the analysis of the feasibility of own fleet of vehicles.
The paper considers the possibilities of transport system management under the condition of external influences. An illustration of the algorithm scheme of solving the optimization problem related to the choice of initial actions is given. The possibility of using prognostic models is shown.
The approaches proposed in the work can be useful in improving the performance of various transportation systems.

Published: December 2022

The criterion for the effectiveness of the organization of heavy traffic on the sections of the Russian railway network is the presence of large correspondences of bulk goods presented by the consignor for transportation. An obstacle to the development of a promising cargo traffic are areas with limited throughput and carrying capacity, the overcoming of which is the organization of heavy traffic. All countries that have railways, at a certain stage of development, face capacity constraints. Summarizing the world experience, we can conclude that the priority in the development of increasing volumes of “heavy cargo” is increasing the weight norms of freight trains. The problem of passing heavy trains for Russian Railways is urgent, because the capacity of some sections has exhausted itself completely. The very timely appearance of heavy traffic becomes one of the options for solving the problem of increasing the carrying capacity of sections and directions and, as a result, creating a reserve of carrying capacity. In this article, a study of the influence of their movement on the carrying capacity and carrying capacity has been carried out.
Aim. To consider the effectiveness of the formation and passage of heavy trains. The influence of the organization of the movement of such trains on the throughput and carrying capacity of railway sections.
Methods. To solve the problem, graphic and analytical methods of mathematical modeling, scientific methods of collecting and processing statistical data, modern achievements in terms of general principles and methods of risk management was used.
Results. The authors have developed a formula for determining the rate of removal of freight trains. The analysis of the influence of the values of the inter-train intervals of freight trains and heavy trains on the removal rate is given.
Practical relevance. As the main alternative to increasing the size of traffic on the main cargo-intensive directions, with a shortage of traffic capacity, it is proposed to use the technology of heavy traffic. In modern market conditions, an increase in the weight and length of a freight train is one of the main reserves for increasing throughput and carrying capacity. By passing heavy trains, we get an increase in carrying capacity. In the article, we prove the consistency of these measures. The increase in carrying and carrying capacity is considered in the context of increasing unified weight standards.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder in terms of clinical symptoms and laboratory findings. It is one of the most common endocrinopathies in women of childbearing age. The development of symptoms and the degree of severity in the course of the disease are the results of changes in the ovaries which may be caused by many genetic, metabolic, neuroendocrine, and environmental factors. The main clinical manifestations are menstrual disorders, difficulties with becoming pregnant, and changes related to hyperandrogenism, e.g., acne, hirsutism. Recognition is above mainly based on Rotterdam criteria.A comprehensive explanation of pathophysiology is still lacking. Nevertheless, it probably is a multifactorial condition with a genetic component. Women suffering from PCOS experience lipid and carbohydrate metabolism disorders, which lead to insulin resistance, obesity, hypertension, and cardiac complications. Insulin resistance affects 65-70% of women and not only plays a significant role in the development of the disease but also contributes to the development of hypertension and dyslipidemia. Potential mechanisms of hypertension in PCOS include endothelial dysfunction, increased aldosterone, and excess testosterone secretion, whereas lipid abnormalities consist of reduced high-density lipoprotein-cholesterol (HDL-C), increased triglycerides, and low-density lipoprotein-cholesterol (LDL-C). All of these factors cause high cardiovascular risk. Currently, therapy considers both lifestyle improvements and medications and must be tailored on a case-by-case basis. It is very important not to consider PCOS only in the context of gynecological and endocrine diseases, but also metabolic changes and cardiovascular diseases. Treatment of PCOS should be individualized and dependent on the predominant disorders, as well as the short- and long-term goals chosen. It also should take the prevention of cardiovascular diseases into account.

Aims Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. Methods This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. Results Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and urinary tract infections were diagnosed more frequently when time to surgery increased. Conclusion Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay. Cite this article: Bone Joint J 2022;104-B(12):1369–1378.
Physician influence on medication adherence, evidence from a population-based cohort
Authors: Yao Shenzhen , Lix Lisa M. , Teare Gary , Evans Charity , Blackburn David F. 
Published: December 2022

Background
The overall impact of physician prescribers on population-level adherence rates are unknown. We aimed to quantify the influence of general practitioner (GP) physician prescribers on the outcome of optimal statin medication adherence.

Methods
We conducted a retrospective cohort study using health administrative databases from Saskatchewan, Canada. Participants included physician prescribers and their patients beginning a new statin medication between January 1, 2012 and December 31, 2017. We grouped prescribers based on the prevalence of optimal adherence (i.e., proportion of days covered ≥ 80%) within their patient group. Also, we constructed multivariable logistic regression analyses on optimal statin adherence using two-level non-linear mixed-effects models containing patient and prescriber-level characteristics. An intraclass correlation coefficient was used to estimate the physician effect.

Results
We identified 1,562 GPs prescribing to 51,874 new statin users. The median percentage of optimal statin adherence across GPs was 52.4% (inter-quartile range: 35.7% to 65.5%). GP prescribers with the highest patient adherence (versus the lowest) had patients who were older (median age 61.0 vs 55.0, p<0.0001) and sicker (prior hospitalization 39.4% vs 16.4%, p<0.001). After accounting for patient-level factors, only 6.4% of the observed variance in optimal adherence between patients could be attributed to GP prescribers (p<0.001). The majority of GP prescriber influence (5.2% out of 6.4%) was attributed to the variance unexplained by patient and prescriber variables.

Interpretation
The overall impact of GP prescribers on statin adherence appears to be very limited. Even “high-performing” physicians face significant levels of sub-optimal adherence among their patients.

Published: December 2022

Nymphaea pubescens is found in the swamplands of Kalimantan Selatan, where it lives in the shape of a basin with divergent levels of water. From February to June 2019, the environment and its development were studied in four zones, with depth differences ranging from 28 to 95 meters in the zone I, 28 to 99 meters in zone II, 54 to 112 meters in zone III, and 55 to 124 meters in zone IV. A transect system is used to zone the area, with fluctuating degrees of water depth reflected in each zone as one moves closer to a basin. Geomorphology in a basin has an essential relief, causing different levels of water surface depth in lebak swampland. The GPS was used to determine the distance traveled.
The purposive sampling technique determines the number of observation stations in each zone. In zone I, waterlily growth generated smaller and more frequent leaves than plants in zone II, which produced smaller and fewer leaves than plants in zone III, which produced smaller and fewer leaves than plants in zone IV. However, the area of the leaves expanded greatly with the depth of water, although the number of leaves fell dramatically with water depth. The organization of the percentage of biomass for the development of shoots and roots was different, even though the total biomass was not statistically different. Waterlily growing in shallower water depths had larger biomass allocations for seeds and lower biomass allocations for roots. Root biomass increased significantly as the depth of the water body increased.
This experiment showed that the deeper the water, the lesser the nutrients and the greater the extent the roots must spread to meet their nutritional requirements. Even though the relationship between leaf area and bloom number weakened as water depth increased, the relationship between leaf number and root number was significantly positive concerning biomass and water depth. Groundwater depth has a significant effect on the allocation of underground biomass (A), with the biomass proportion decreasing as water depth increases from 28 to 95 cm in zone I = 53.1 percent to 28–99 cm in zone II = 53.7 percent to 55–124 cm in zone III = 48.6 percent in zone IV = 42.4 percent. Because water depth has a considerable effect on the average aboveground biomass–to–underground biomass ratio, the average root crown ratio decreases as water depth increases. Among the lowest average ratios found are those found at a water depth of 55–124 cm in zone IV (ratio of 0.54 ± 0.2), while the highest average percentage found is that found at a water depth of 28–95 cm in the zone I (ratio of 1.25 ± 0.61).
Synthesis of National Research on School Climate in Czech Republic
Authors: Kachnic Filip , Cohen Jonathan 
Published: November 2022

Educators have been attuned to the importance of school climate for more than 100 years (Cohen, McCabe, Michelli, & Pickeral, 2009). School climate is an ecologically informed idea that recognizes individual, small and large group trends about a range of safety, relationships, teaching & learning and environmental issues that shape student learning and their development. School climate is measurable. Over the last three decades, school climate has become a growing focus for educational practice and policy leaders around the world (Ruiz et al, 2021; Cohen & Espelage, 2020; Thapa et al, 2013). As a result, we suggest that school climate and school-climate informed improvement efforts need to be studied on national levels (Vicente et al, 2021). Berkowitz's recent national-level study on positive school climate and its relationship to socioeconomic status and achievement of Arabic speaking students in Israel (Berkowitz, 2017 & 2020), has proved to be highly relevant bringing solutions to global issues (Bradshaw, et al. 2021). Our scoping review was conducted to advocate for the importance of school climate and for its role to inform national policy. It took place in the Czech Pedagogical Bibliographic Database of the J. A. Komenský Pedagogical Library in June 2020. The reasons for choosing this database were its terminologically unified annotation of bibliographic records using the Czech Pedagogical Thesaurus and its intentional scope to cover pedagogical literature (Email communication, Petišková, May 6th, 2020; Petrovičová, 2012). In the first step, we searched by the keyword "school climate" (in Czech) and identified a total of 383 bibliographic records. Using a programming script created for the purpose of our study by a university librarian, we identified a total of 2550 keyword combinations with the keyword "school climate." The keyword "school climate" was most often associated with the keyword "primary school" (N = 113). The second most frequent combination was "school climate" and "school environment" (N = 103). The third most numerous combination was "school climate" and "interpersonal relationships" (N = 92). The fourth most numerous combination was "school climate" and "teacher-student relationship" (N = 92). School climate is being studied in the Czech Republic on the primary and lower secondary school level, as well as in relational contexts.
Interligando Conceitos sobre Saúde no Ensino de Biologia Celular
Authors: Michelotti Angela , da Silva Loreto Elgion Lucio 
Published: November 2022

De acordo com a Base Nacional Comum Curricular, o ensino sobre “células” no ensino fundamental II aborda principalmente os tipos celulares e organelas citoplasmáticas. Na maioria das vezes, estas estruturas são apresentadas de forma teórica, com o uso de livros didáticos, mas sem contextualização de como estas estruturas microscópicas, estão intimamente associadas ao nosso cotidiano. O presente trabalho tem como objetivo buscar quais as concepções os alunos de 8º e 9º ano do ensino fundamental II trazem sobre conceitos relacionados à biologia celular, como os envolvendo a história da ciência, diferenciação celular, microrganismos, multiplicação celular e cicatrização. Estes conceitos são importantes para compreender a organização e funcionamento do corpo humano e, portanto, fundamentais para uma efetiva alfabetização cientifica. A pesquisa foi realizada com 114 alunos, de turmas de 8º e 9º ano, de duas escolas públicas. Um “questionário em três camadas” foi aplicado, onde a primeira camada é uma questão de múltipla escola, com três alternativas, sendo uma opção correta e duas erradas. Na segunda camada, o aluno deve escolher a opção que melhor completa (explica/justifica) a alternativa escolhida na primeira parte, e contém três alternativas, sendo uma certa e duas erradas. Já a terceira parte é o nível de confiança ao responder as questões acima, se o respondente tem certeza de sua resposta na primeira e segunda camada ou não. Percebe-se que os alunos compreendem que os animais e as plantas são constituídos por células, e estes compõem os tecidos e órgãos. Os educandos apresentaram pouco conhecimento em relação a história da ciência, não identificando quem visualizou as primeiras células, tão pouco conseguem interligar que os microrganismos apresentam benefícios, demonstrando apenas o aspecto nocivo para o corpo humano. Ao apresentarmos aos alunos os tipos celulares eles apresentaram dificuldades em identificar as células eucarióticas e procarióticas. Aos serem questionados sobre a relação entre o corpo humano e os microrganismos, o processo de cicatrização e multiplicação celular, e o processo inflamatório, percebe-se um decréscimo em seus acertos, pois nessas questões envolviam contextualização e a necessidade de interligar dois ou mais conceitos para responder. Os documentos norteadores vigentes trazem conteúdos teóricos e abstratos e que não são contextualização com fatos do cotidiano dos alunos.
