Confirmatory Factor Analysis and Validity of the Sexual Harassment Scale in Football Refereeing
Authors: Sánchez Josefa , Serrat Sara , Castillo Estefanía , Nuviala Alberto
Published: February 2021

Inequalities between men and women in the workplace are reflected in professional sports, specifically football refereeing. This phenomenon sometimes becomes sexual harassment since it is a stereotypically considered male profession in which women are a minority. To measure that behavior, it is necessary to count on valid and reliable tools. Therefore, the goal of this study was to determine the factorial structure and the discriminant and convergent validity of the ‘sexual experiences questionnaire’, version of the Department of Defence (SEQ-DoD). Eighty-nine male football referees and ninety-four female football referees, with a mean age of 23.30 ± 4.85 years, participated in this studio conducted questionnaire in Andalusia, Spain. A confirmatory factor analysis was performed using the robust maximum-likelihood estimation method. The goodness of fit was assessed, and the factorial invariance was calculated to determine the stability of the model. Subsequently, the validity was confirmed. The results corroborated the validity and reliability of the questionnaire adapted to the population studied. Therefore, it can be used as a research instrument.
Educational Assortative Mating and Health: A Study in Chinese Internal Migrants
Authors: Zhang Ling , Tan Xiaodong
Published: February 2021

Previous studies have shown that marriage is related with people’s health. Based on data from the Volume A of China Migrants Dynamic Survey (CMDS_A) in 2017 (N = 127,829), this study attempted to document the degree of educational assortative mating in Chinese internal migrants, as well as how it evolves over time, and further analyze the relationship between educational assortative mating and people’s self-rated health (SRH). The results indicated that the proportion of educational homogamy kept increasing and gradient marriage kept decreasing over time both in male and female. “Educational homogamy” (58.8%) and “male more educated” (27.2%) were still the main marital education matching patterns in first-married couples of Chinese internal migrants. Educational homogamy was beneficial to promote people’s SRH and educational hypogamy would impair their SRH, and the negative effects of educational hypogamy on SRH was stronger in female than in male. The gender equality of educational opportunities increases the degree of educational assortative mating in Chinese internal migrants. Educational attainment is playing a more and more important role in “love” marriages. “Likes attract likes” is not just about love, but also an important part of health.
Why Do Students Walk or Cycle for Transportation? Perceived Study Environment and Psychological Determinants as Predictors of Active Transportation by University Students
Authors: Teuber Monika , Sudeck Gorden
Published: February 2021

University students are particularly at risk to suffer from physical and psychological complaints and for not fulfilling health-oriented physical activity (PA) recommendations. Since PA is linked with various benefits for health and educational outcomes, the group of students is of particular interest for PA promotion. Although active commuting has been identified as a relevant domain of PA in order to gain the various benefits of PA, little knowledge is available with respect to university students. This study tested conditions in the study environment, as well as personal motivators and barriers, as determinants for the active transportation of university students. Using a cross-sectional convenience sample of a university in the southwest of Germany (n = 997), we applied factor analyses to bundle relevant information on environmental and psychological determinants (adapted NEWS-G; adapted transport-related items from an Australian university survey) and blockwise hierarchical regressions. The objective was to analyze associations between the bundled determinants and self-reports on PA for transport-related walking and cycling (measured by the EHIS-PAQ). Results revealed associations between transport-related cycling and the perceived study environment (e.g., high automobile traffic) as well as certain personal motivators and barriers (e.g., time effort or weather conditions). The study contributes to the knowledge about determinants that are important for the development and improvement of public health interventions for students in a university setting.
Harm Perception in Response to Pictorial Warning Labels Predict Higher Non-Smoking Intention among Korean Adolescents
Authors: Hwang Jun Hyun , Park Soon-Woo
Published: February 2021

Because of recent controversy surrounding the use of excessively graphic pictorial warning labels (PWL) on cigarette packs in South Korea, it is necessary to provide evidence to evaluate their effectiveness as a tobacco control policy according to the harm perception they evoke. An analysis was performed using a nationally representative survey conducted six months after the introduction of PWLs in South Korea. Among 62,276 survey participants, 43,231 students from grades 7–12 who had seen a PWL in the past 30 days comprised the research sample. Non-smoking intention was evaluated according to the harm perception evoked by PWLs, which predicted higher non-smoking intention among adolescents. Non-smoking intention was particularly higher in daily smokers with harm perception (52.0%) than those who have never smoked and have no harm perception (40.1%). In the case of those who perceived harmfulness, non-smoking intention was formed in about 45% of daily smokers who had no experience of trying to quit in the last 12 months. Therefore, it is important to select PWLs that can arouse in adolescents sufficient harm perception of smoking.
Nature Exposure and Its Effects on Immune System Functioning: A Systematic Review
Authors: Andersen Liisa , Corazon Sus Sola , Stigsdotter Ulrika Karlsson
Published: February 2021

Given the drastic changes in our lifestyles and ecosystems worldwide, the potential health effects of natural environments have grown into a highly pervasive topic. Recent scientific findings suggest beneficial effects from nature exposure on human immune responses. This review aims at providing a comprehensive overview of literature published on immunomodulatory effects of nature exposure by inhalation of natural substances. A systematic database search was performed in SCOPUS and PubMed. The quality and potential bias of included studies (n = 33) were assessed by applying the EPHPP (Effective Public Health Practice Project) tool for human studies and the ARRIVE (Animal Research: Reporting of In Vivo Experiments) and SYRCLE (Systematic Review Centre for Laboratory Animal Experimentation) tools for animal studies. The synthesis of reviewed studies points to positive effects of nature exposure on immunological health parameters; such as anti-inflammatory, anti-allergic, anti-asthmatic effects or increased NK (natural killer) cell activity. Decreased expression of pro-inflammatory molecules, infiltration of leukocytes and release of cytotoxic mediators are outcomes that may serve as a baseline for further studies. However, partially weak study designs evoked uncertainties about outcome reproducibility and key questions remain open concerning effect sizes, duration of exposure and contributions of specific vegetation or ecosystem types.

Published: February 2021

Chile is a mining country, where waste mining is frequently found in the vicinity of inhabited areas. To explore the association between metal exposure and alterations in glucose metabolism, inflammatory status, and oxidative stress in individuals with chronic exposure to metals, a cross-sectional study was performed with 25 volunteers, between 45–65 years old. Inductive coupled plasma mass spectrometry (ICP-MS) was used to measure urinary levels of total arsenic (As) and its metabolites, cooper, nickel, chromium, and lead. Lipid profile, glucose, and insulin were measured in blood, as well as inflammation (interleukin-6, IL-6) and oxidative stress (8-hydroxy-2′deoxyguanosine, 8-OHdG) markers. Increased levels of Low-density lipoprotein, high-density lipoproteins, cholesterol and 8-OHdG, and the index for homeostasis model assessment—insulin resistance (HOMA-IR) were observed in 72%, 60%, and 56% of the volunteers, respectively. Blood-glucose levels were correlated with dimethylarsinic acid (DMA) (R2 = 0.47, p = 0.019), inorganic As (Asi) (R2 = 0.40, p = 0.012), and Ni (R2 = 0.56; p = 0.044). The models with these compounds explained 72% of the glycemia variability (βDMA = −6.47; βAsi = 6.68; βNi = 6.87). Ni showed a significantly influence on IL-6 variability (β = 0.85: R2 = 0.36). Changes in glycemia could be related to exposure to low levels of Asi and Ni, representing risk factors for metabolic diseases. Body mass index would confuse the relation between IL-6 and Ni levels, probably due to known chronic inflammation present in obese people.
Optimal Reinsurance Problem under Fixed Cost and Exponential Preferences
Authors: Brachetta Matteo , Ceci Claudia
Published: February 2021

We investigate an optimal reinsurance problem for an insurance company taking into account subscription costs: that is, a constant fixed cost is paid when the reinsurance contract is signed. Differently from the classical reinsurance problem, where the insurer has to choose an optimal retention level according to some given criterion, in this paper, the insurer needs to optimally choose both the starting time of the reinsurance contract and the retention level to apply. The criterion is the maximization of the insurer’s expected utility of terminal wealth. This leads to a mixed optimal control/optimal stopping time problem, which is solved by a two-step procedure: first considering the pure-reinsurance stochastic control problem and next discussing a time-inhomogeneous optimal stopping problem with discontinuous reward. Using the classical Cramér–Lundberg approximation risk model, we prove that the optimal strategy is deterministic and depends on the model parameters. In particular, we show that there exists a maximum fixed cost that the insurer is willing to pay for the contract activation. Finally, we provide some economical interpretations and numerical simulations.

Authors: Vinoth Kumar Sri Hari Bharath , Muydinov Ruslan , Szyszka Bernd
Published: February 2021

The past decade has seen enormous efforts in the investigation and development of reduced graphene oxide (GO) and its applications. Reduced graphene oxide (rGO) derived from GO is known to have relatively inferior electronic characteristics when compared to pristine graphene. Yet, it has its significance attributed to high-yield production from inexpensive graphite, ease of fabrication with solution processing, and thus a high potential for large-scale applications and commercialization. Amongst several available approaches for GO reduction, the mature use of plasma technologies is noteworthy. Plasma technologies credited with unique merits are well established in the field of nanotechnology and find applications across several fields. The use of plasma techniques for GO development could speed up the pathway to commercialization. In this report, we review the state-of-the-art status of plasma techniques used for the reduction of GO-films. The strength of various techniques is highlighted with a summary of the main findings in the literature. An analysis is included through the prism of chemistry and plasma physics.
The Nonlinear Relation between Institutional Ownership and Environmental, Social and Governance Performance in Emerging Countries
Authors: Martínez-Ferrero Jennifer , Lozano María-Belén
Published: February 2021

This paper examines how the level of institutional ownership affects environmental, social, and governance (ESG) performance in emerging countries by jointly investigating a nonlinear relationship. By examining an international sample composed of 17,318 firm–year observations from the period 2012–18 for 16 emerging countries, our findings reveal that the ESG performance of firms located in emerging countries depends on the level of influential institutional ownership, and displays a U-shaped relation, particularly for environmental disclosure. Institutional investors with low ownership are less likely to promote higher ESG performance in emerging countries, although this effect is attenuated when institutional ownership reaches a significant percentage, constituting a critical mass.

Published: February 2021

Geographically fine-grained population information is critical for various urban planning and management tasks. This is especially the case for the Chinese cities that are undergoing rapid development and transformation. However, detailed population data are rarely available in comprehensive and timely means. Therefore, appropriate approaches are needed to estimate populations from available data sets in a systematic way to support the continuous demand from urban analytics and planning. Population synthesis approaches such as Iterative Proportional Fitting (IPF) were developed to combine microdata samples with marginal statistics about population characteristics at aggregated spatial levels in order to expand the microdata sample into a complete synthetic population. This paper presents the framework for and the implementation of a geospatial platform for supporting the generation and exploration of spatially detailed urban synthetic populations. The platform provides analytical and visualization tools to support the quick generation of a full urban population with critical attributes based on the latest data available. The case of the synthetic population of Chongqing is used to illustrate the population information and types of visualization that are facilitated.

Authors: Wang Jun , Yin Jingbo , Khan Rafi Ullah , Wang Siqi , Zheng Tie
Published: February 2021

The cruise market has developed rapidly in recent years. The opulence of the cruise market has also augmented the demand for the cruise construction industry. Cruise ship construction is a huge and intricate heavy industry that can cause serious environmental problems. Therefore, optimal use of advanced logistics systems, to meet the demands at the lowest possible cost and unnecessary waste, has become a key issue. This paper developed two typical inbound logistics system modes based on JIT (Just In Time)-logistics policy and formulated two single-objective nonlinear models to simultaneously determine the ordering strategy under the inbound logistics system and the optimal selection strategy of two typical inbound logistics modes. Numerical experiments depicted the variations of optimal inbound logistics mode over three different kinds of cruise parts. These two models could provide insights in making inbound logistics decisions, and serve as a reference in the mass customization logistics service for cruise ship construction to control costs, which is helpful for promoting the sustainability of the cruise market.

Published: February 2021

Healthy aging is one of the most important aspects of human life as it can significantly improve its quality. Therefore, it is necessary to promote successful aging as a significant and important part of maintaining physical and mental well-being in the elderly. One of the strategies to enhance the elderly’s well-being may be also foreign language learning. The purpose of this study is to compare and discuss what effect foreign language learning (FLL) might have on subjective well-being among healthy older individuals in the Czech Republic and Poland, using factor analysis as the primary statistical method. The research sample consisted of two experimental groups of seniors; one from the Czech Republic (n = 92) and another from Poland (n = 100). The main research methods included a questionnaire survey and factor analysis. The factor analysis revealed the four significant factors and their correlations with demographic variables, whose results showed the effect of FLL on seniors’ subjective well-being. In conclusion, learning a foreign language at an older age seems to be one of the key strategies to maintain a subjective feeling of happiness at a relatively high level in elderly people without necessary pharmacological intervention.
Evaluation of Urban-Scale Building Energy-Use Models and Tools—Application for the City of Fribourg, Switzerland
Authors: Todeschi Valeria , Boghetti Roberto , Kämpf Jérôme H. , Mutani Guglielmina
Published: February 2021

Building energy-use models and tools can simulate and represent the distribution of energy consumption of buildings located in an urban area. The aim of these models is to simulate the energy performance of buildings at multiple temporal and spatial scales, taking into account both the building shape and the surrounding urban context. This paper investigates existing models by simulating the hourly space heating consumption of residential buildings in an urban environment. Existing bottom-up urban-energy models were applied to the city of Fribourg in order to evaluate the accuracy and flexibility of energy simulations. Two common energy-use models—a machine learning model and a GIS-based engineering model—were compared and evaluated against anonymized monitoring data. The study shows that the simulations were quite precise with an annual mean absolute percentage error of 12.8 and 19.3% for the machine learning and the GIS-based engineering model, respectively, on residential buildings built in different periods of construction. Moreover, a sensitivity analysis using the Morris method was carried out on the GIS-based engineering model in order to assess the impact of input variables on space heating consumption and to identify possible optimization opportunities of the existing model.

Authors: Gajić Aleksandra , Krunić Nikola , Protić Branko
Published: February 2021

The classification of rural and urban areas presents an important topic both in scientific research and in the practice of spatial planning, regional policy making, and territorial governance. Taking into account the multidimensionality of these areas, this paper aims to provide a classification framework design for rural areas in Serbia. After selecting the relevant indicators, which were included to reflect the main demographic, economic, and physio-geographical characteristics of the Serbian rural areas, multivariate analysis (principal component method and factor analysis) was used to determine the main factors in the delimitation and classification of rural and urban areas. The last step of the conducted methodology used cluster analysis (CA) that identified six types of areas with similar characteristics. The results of this study and applied methodology can improve the existing rural–urban classifications and help planners and policy makers in the adaptation of strategic development documents.
With or without a Vaccine—A Review of Complementary and Alternative Approaches to Managing African Swine Fever in Resource-Constrained Smallholder Settings
Authors: Penrith Mary-Louise , Bastos Armanda , Chenais Erika
Published: February 2021

The spectacular recent spread of African swine fever (ASF) in Eastern Europe and Asia has been strongly associated, as it is in the endemic areas in Africa, with free-ranging pig populations and low-biosecurity backyard pig farming. Managing the disease in wild boar populations and in circumstances where the disease in domestic pigs is largely driven by poverty is particularly challenging and may remain so even in the presence of effective vaccines. The only option currently available to prevent ASF is strict biosecurity. Among small-scale pig farmers biosecurity measures are often considered unaffordable or impossible to implement. However, as outbreaks of ASF are also unaffordable, the adoption of basic biosecurity measures is imperative to achieve control and prevent losses. Biosecurity measures can be adapted to fit smallholder contexts, culture and costs. A longer-term approach that could prove valuable particularly for free-ranging pig populations would be exploitation of innate resistance to the virus, which is fully effective in wild African suids and has been observed in some domestic pig populations in areas of prolonged endemicity. We explore available options for preventing ASF in terms of feasibility, practicality and affordability among domestic pig populations that are at greatest risk of exposure to ASF.
Enhancement of Anaerobic Digestion of Waste-Activated Sludge by Conductive Materials under High Volatile Fatty Acids-to-Alkalinity Ratios
Authors: Calabrò Paolo S. , Fazzino Filippo , Limonti Carlo , Siciliano Alessio
Published: February 2021

Anaerobic digestion (AD) represents a suitable option for the management of the waste-activated sludge (WAS) produced in municipal wastewater treatment plants. Nevertheless, due to its complex characteristics, WAS is often barely degradable under conventional anaerobic processes. The use of conductive materials during AD provides a promising route for enhancing WAS digestion, through the effects of direct inter-species electron transfer (DIET). The present paper aims to evaluate the effects of the addition of four different materials—granular activated carbon (GAC), granular iron, and aluminium and steel scrap powders—in semi-continuous lab-scale reactors under very high volatile fatty acids-to-alkalinity ratios. In particular, the use of metallic aluminium in WAS digestion was investigated for the first time and compared to the other materials. The AD of WAS without the addition of conductive materials was impossible, while the use of steel powder and zero-valent iron is shown not to improve the digestion process in a satisfactory way. On the contrary, both GAC and Al allow for effective WAS degradation. At stable conditions, methane yields of about 230 NmLCH4/gVS and 212 NmLCH4/gVS are recorded for GAC- and Al-amended reactors, respectively. These two materials are the most promising in sustaining WAS AD through DIET also in case of unbalanced volatile fatty acids-to-alkalinity ratios.

Published: February 2021

Inga edulis es una especie ampliamente utilizada como sombrío en la zona cafetera de Colombia. En esta in-vestigación se estudió la fenología de esta especie en un agroecosistema ganadero y otro cafetero del departa-mento del Quindío entre julio de 2005 y junio de 2006. Se realizaron observaciones mensuales de las fenofases vegetativa y reproductiva, se marcaron flores con el fin de observar la duración de los eventos reproductivos y describir el proceso de antésis. Inga edulis presentó todas las fenofases reproductivas y vegetativas, aunque la caída de follaje no fue evidente. En ambos agroecosistemas los árboles presentaron dos periodos de floración con una duración de 4 a 6 meses, mientras que la fructificación, la brotación y la caída del follaje fueron cons-tantes. La intensidad de algunas fenofases mostró una coincidencia con la precipitación. Nuestros resultados muestran diferencias en el periodo de antésis y sincronía de las fenofases con respecto a otros estudios en el Neotrópico, lo que sugiere una posible variación fenológica a lo largo de su distribución geográfica.

The challenge of comparing EU Member States judicial data
Authors: Ontanu Alina , Velicogna Marco
Published: February 2021

The number of cases is measured through a broad range of quantitative variables used in various studies and policy papers as key indicators of the volume of activity of national courts. Additionally, these variables, together with other data (e.g. time needed to resolve a case, number of judges, etc.) are part of a broader discourse on the efficiency of justice systems. However, such discourse can be problematic when data is not actually comparable. To raise the attention on this very relevant but poorly explored topic, this paper analyses the comparability of the caseload data by focusing on apparently simple categories like civil and commercial litigious or non-litigious cases and administrative cases. The EU Justice Scoreboard and CEPEJ data and national case definitions in France, Italy, and Romania are used to assess the most relevant justice EU datasets. The findings point towards significant differences between analysed systems that suggest extreme caution should be exercised when using such data for scholarly, legislative or policy discourses.
Humanitarizing mobility in Mexico
Authors: Benincasa Valentina , Cortés Almudena
Published: February 2021

This article analyzes the process of humanitarization of Central American migration that crosses and resides in Mexico. Our starting point is the contemporary debates on the anthropology of humanitarianism and its relation to migration as an object of intervention. It aims to reflect on the changes that have occurred in the North American region and on how civil society actors are constructing Central American migration as a humanitarian problem. The fieldwork on which this article is based was carried out in 2019 and consisted of conducting in-depth interviews with the main NGOs that are in charge of humanitarian work in the state of Puebla combined with the observation of various public events. The analysis shows that the humanitarian discourse has been configured in an ambiguous way as it is built between the application of security and migration control policies and the humanitarian attention of the migrant population.
“Look who is laughing now”
Authors: Jump Deborah
Published: February 2021

This paper’s aim is to further current thinking around young men’s perceptions and understanding of violence, and the use of boxing as a vehicle in the prevention of repeat victimization. The focus is on the use of bodily or physical capital, and the ways in which men draw upon this resource to ward off attacks to identity and psyches, especially those perceived as disrespectful. It will draw on data from The Criminology of Boxing, Violence and Desistance (Jump 2020), and present overarching ideas from Tyrone, a psychosocial case study highlighting the underpinning theory and its development. This paper disrupts common discourses that argue that boxing is a panacea for all violence, and thus presents more subjective nuanced accounts of men’s lives in the gym, and the streets. In using the term “physical capital”, I employ Wacquant’s (1995) theory, and suggest that boxers not only use their body as a “form of capital” (p. 65), but that the physical capital accrued through the corporeal praxis of boxing, is actually a way to disavow prior victimization, and invest in the prevention of repeated traumatic scenarios.
“The body says: I am a party”
Authors: Ghisleni Pâmela Copetti , Lucas Doglas Cesar
Published: February 2021

The rationalism of the seventeenth century inaugurated a new way of thinking to establish that access to the world occurred through rationality. The individualist conception of society that emerged from the eighteenth century, despite having placed the subject in the center, made it from its psychic dimension, relegating the biological body to the second place. In the twentieth century however, Freud recalls the theme of the body to enter again the individual in his materialistic body. Therefore, it was restored and deepened the theme of meat, carcass, organic and biological body. Thus, the present study aims, from the hypothetical-deductive method, to analyze the (im)possibility of body regulation, especially the female one, by the contemporary law, and its practical implications for women to, in the end, conclude that the body and their narratives are at the root of inequality and gender oppression.
Women at the bench: Does it make a difference?
Authors: Addadzi-Koom Maame Efua , Nkansah Lydia A.
Published: February 2021

The impact of women judges in addressing gender-based issues, particularly in Africa, is largely under-researched both at the regional and country-specific levels. This paper researches on the impact of women judges in selected gender-based cases in Ghana – that is spousal property rights cases. The paper seeks to answer the primary question: in addressing spousal property rights in Ghana, have women at the bench made a difference? In answering this question, a doctrinal analysis of purposively selected cases was conducted which led to a finding that women judges did not make a difference in the development of the law on spousal property rights in Ghana. The findings and recommendations made in this paper are expected to contribute to the understanding of how female participation in judging gender-based cases have influenced and could potentially influence the interests and rights of women as well as to inform the policy choice of women judges.

Authors: HATİPOĞLU ŞAHİN Betül , TERECİ Ayşegül
Published: February 2021

Mass housing played an important role in changing the face of the cities. The Municipality Law No.5393 which gave the right to municipalities to build mass housing were factors that have accelerated the mass housing production. The main goal of local administrations is to build houses in the most rapid and economic way for group of people with low income. However, such production has posed problems in terms of quantity and quality. This research has been conducted to measure the satisfaction levels of users from mass housing projects which are implemented under the leadership of the municipality in Konya. The existing residences in the area selected for the project were demolished swiftly and then mass housing was again built swiftly. Determining how the users in the region are affected by this change and their satisfaction with this matter is one of the main goals of this study. A scale was created by scanning the housing satisfaction parameters in the literature for the purpose of this study. In order to find out the satisfaction with the physical space, 5 mass housing areas, which share similarity in terms of settlement texture density and housing typology, were selected as sample study area from the 22 projects built by the district municipality. In the satisfaction and space analysis, user satisfaction in the mass housing projects produced by the municipality was examined together with the demographic findings. This research will serve as a baseline for future research since it will provide ready and comparable data.

Authors: ERTEN Süleyman , KOŞAN Meltem , İŞGEN Furkan , DEMİRCİ Esra , AKTAŞ Mustafa
Published: February 2021

Energy efficiency and the amount of refrigerant in heat exchangers used in cooling systems has recently been an important research subject. In this study, in order to compare and analyze different types of evaporators, industrial refrigerators were designed and in this context, test setups in accordance with TS EN ISO 23953-2 standard were produced. R290 (propane) was used as the refrigerant in the designed system. During the experiment, temperature-pressure measurements were taken at a certain point in the cooling system equipment of the products, which were cooled every minute, and test data were recorded. As a result of the data obtained from the experimental results, while the temperature difference of the air entering and leaving the evaporators was 6.797 ℃ in the first system using ½” tube diameter evaporator, it was calculated as 7.052 ℃ in the corrugated and hydrophilic coated second system using 3/8” tube diameter. In the experimental setups, the energy consumed in the first and second systems and the masses of R-290 refrigerant were measured as 24.64 kWh, 23.39 kWh and 700 grams, 430 grams, respectively. Consequently, it was calculated that the second system was 5.073% and 38.57% more efficient in terms of energy efficiency and the refrigerant mass used.

This study aimed to determine the importance levels of mathematics lecture achievement, Turkish lecture achievement, Higher Education Admission Exam score, academic self-efficacy, attitude towards vocational education, academic motivation and mother and father education on the academic achievement of vocational schools of higher education students using the artificial neural network method. The data was obtained through 468 students from vocational schools of higher education at two different universities in Turkey. According to the quantitative research methodology, the correlational research design was used. The artificial neural network analysis results revealed that mathematics lecture achievement, Turkish lecture achievement and academic self-efficacy were the most critical variables that predicted the academic achievement of vocational schools of higher education students. These variables were followed by mother education level, father education level, attitude towards vocational education, Higher Education Admission Exam score and academic motivation. The results suggest that the effectiveness of the Higher Education Admission Exam score, which contributes very little to predict the academic achievement of vocational education students, need to be more questioned.﻿

Цель работы – получить кондитерский продукт, отвечающий требованиям современного потребителя. Взяв в качестве основного сырья творожную сыворотку, можно получить обладающий диетическими свойствами продукт: легкоусвояемый, питательный, обогащённый альбумином. На основе применяемых в настоящее время технологий производства мармеладов была разработана альтернативная, без использования сахара, патоки и прочих компонентов с высоким гликемическим индексом. А также был произведён опытный образец по собственной рецептуре с использованием сырья, отвечающего требованиям органической продукции. В состав готового продукта вошли сыворотка молочная, агар, подсластитель стевиозид. В варианте с добавкой был использован свежевыжатый морковный сок с целью нейтрализации специфического привкуса стевиозида. Исследования показали, что оба образца желе мармеладного по органолептическим показателям и значению титруемой кислотности отвечают требованиям ГОСТ. Предлагаемый продукт не имеет аналогов на отечественном рынке.

The purpose of the work is to obtain a confectionery product that meets the requirements of a modern consumer. Having taken curd whey as the main raw material one can get a product with dietary properties: easily digestible, nutritious, enriched with albumin. On the basis of the current technologies for the production of marmalades, an alternative, without the use of sugar, syrop and other components with a high glycemic index has been developed. And a prototype was produced according to its own formula using raw materials that meet the requirements of organic products. The complete product contains milk whey, agar, stevioside sweeting agent. In the version with flavour freshly squeezed carrot juice was used to neutralize the specific stevioside flavor. The researches have shown that both samples of marmalade jelly meet GOST requirements in terms of organoleptic indices and titrated acidity. The proposed product has no analogues in the domestic market.

Рассмотрена проблема напряжённо-деформированного состояния решета электростатического сепаратора при ударной нагрузке с различными уровнями интенсивности импульса столкновения с применением метода конечных элементов. Проводилось изучение поперечного воздействия тела в виде точки массы или конечного тела на листовые структуры следующего типа: решето; решето, усиленное рёбрами; решето с повреждениями. Для решения обозначенной задачи использовался метод конечных элементов (FEM) в форме смещения. Этот метод был реализован в программном комплексе SolidWorks с приложением Simulation. Исследования были проведены для динамических нагрузок с материалами решёт: нержавеющая сталь и стеклотекстолит. Оценка результатов проводилась путём анализа эпюр напряжений и деформации модели. Проведённые расчёты показали, что учёт размеров ударного тела приводит к уменьшению значений деформации и эквивалентных напряжений. Для повышения эффективности системы очистки плоских решёт в электростатическом сепараторе в качестве материала решета можно применять как нержавеющую сталь, так и стеклотекстолит.

The problem of stress-strain state of electrostatic separator screen at impact load with different levels of collision pulse intensity using finite element method is considered. The transverse effect of the body in the form of a point of mass or a final body on sheet structures of the following type was studied: screen, screen reinforced by ribs, screen with faults. To solve the designated problem, the finite element method (FEM) in the form of displacement was used. This method was implemented in the software complex SolidWorks with the Simulation application. Researches were conducted for dynamic loads with screen materials: stainless steel and fiber-glass plastic. Evaluation of the results was carried out by analyzing the stress and strain diagrams of the model. The conducted calculations have shown that taking into account the dimensions of the impact body leads to a decrease in deformation values and equivalent stresses. To increase the efficiency of the flat screen cleaning system in an electrostatic separator, both stainless steel and glass textile can be used as a screen material.

Sewer pipelines are usually operated with little maintenance after installation. After years in service, sewer pipes get old and deteriorated. The present research is the first study that attempts to inspect the condition of sewer pipelines in the Bangkok Metropolitan Area. A robot with Closed Circuit Television (CCTV) was used to capture video and images of the interior of the sewer pipelines between two manholes. The system was operated by Utility Business Alliance (UBA) Company. The condition of the sewer pipelines was visually analyzed in line with the scoring and grading system of New Zealand’s pipe inspection manual. CCTV footage was received from UBA, and each meter of the sewer pipelines was visually inspected, scored, and graded. The study area included 22 randomly selected roads around Dindaeng District. For the structural condition, surface damage was found in all of the 89 inspected pipes. Joint faulty and crack longitudinal were found in approximately 60% of the inspected sewer pipelines. Infiltration present was found in 33% of the inspected pipes, while crack circumferential and crack multiple were minimal in the study area. For the service condition, obstruction temporary, debris silty, and debris greasy were found in 15%, 11%, and 4% of the inspected sewer pipelines, respectively. The grades of the structural condition were mainly between 4 and 5, indicating that most of the sewer pipelines in the area would need rehabilitation programs. The grades of the service condition were between excellent and good. This is the first time that such a program has been conducted in Thailand. The information of the condition of the pipelines and the inspection and characterization methods should be used as a reference for maintenance programs and future assessment programs. The adjustment or development of the inspection manual should be done in collaboration with local contacts.
