Dynamic Stability of a Three-Layer Beam – Generalisation of the Sandwich Structure Theory
Authors: Magnucki Krzysztof , Magnucka-Blandzi Ewa
Published: December 2023

The work focuses on the dynamic stability problem of a simply supported three-layer beam subjected to a pulsating axial force. Two analytical models of this beam are developed: one model takes into account the non-linear hypothesis of cross-section deformation, and the other takes into account the standard “broken line” hypothesis. Displacements, strains and stresses for each model are formulated in detail. Based on the Hamilton principle, equations of motion are determined for each of these models. These systems of two differential equations for each model are approximately solved with the consideration of the axial pulsating force, and the fundamental natural frequencies, critical forces and the Mathieu equation are determined. Detailed studies are performed for an exemplary family of beams. The stable and unstable regions are calculated for the three pulsating load cases. The values of fundamental natural frequencies and critical forces of exemplary beams calculated from two models are compared.
Metabolic disturbances in sedentary and active Polish male students with normal body mass index and waist circumference
Authors: Malara Marzena , Widłak Patrycja
Published: December 2023

Study aim: To evaluate circulating lipoproteins, glucose, insulin and the index of insulin resistance (HOMA-IR) in male Polish students with normal BMI and waist circumference (WC) in the context of their physical activity.

Material and methods: A total 170 male students with normal BMI and WC less than 102 cm were accepted for the study (56 sedentary and 114 physically active). Body weight and height were determined using standard medical equipment. Waist circumference was measured using non-stretchable tape. The percentage of body fat was determined from the sum of the thickness of four skinfolds. Circulating lipoproteins, glucose and insulin level was determined.

Results: Active participants had significantly lower plasma TC, LDL-C, TC/HDL ratio, LDL/HDL ratio, insulin and HOMA-IR compared to sedentary subjects (P < 0.001). However, even among active participants, as many as 58% were characterized by high TG, 17% high TC, 12% high LDL-C and 20% high TG/HDL ratio.

Conclusion: In male students with normal body composition according to BMI and WC distorted metabolic variables were observed. Additionally, physical activity markedly decreased but not eliminated these disturbances. Thus, using BMI and WC for body composition classification as healthy possibly provide a false results concerning metabolic status.

This study aimed to examine the pollen and pollinia morpho-structure of 18 horticultural Apocynaceous species. Advanced light and scanning electron microscopy (LM and SEM) were used to elaborate on and examine the systematic importance of pollen and pollinia micromorphology. Pollen grains were first acetolysed, which was followed by visualisation of their sculpturing features. The quantified data were subjected to statistical tools to elucidate dendrogram clustering and principal component analysis to reveal pollen/pollinia morphotypes. The size of pollen is variable, ranging from 113.45 μm in Cascabela thevetia to 23.4 μm in Alstonia scholaris. The study revealed tetrad, tetraporate, and tricolporate grains. Sculpturing (exine ornamentation) varies from reticulate perforate to reticulate. Pollinum shape was observed to be narrow oblong, obovate, orbicular, and reniform. Reticulate-psilate sculptural features were prominent among pollinia surfaces. Based on examination, it was ascertained that the minimum exine thickness in Periploca aphylla was 4.9 μm, whereas the corresponding number in Cryptolepis dubia was 1.35 μm. Taxonomic identification keys were constructed separately based on pollen/pollinia characters to identify the Apocynaceous taxa. In the presented study, seven pollen shapes were observed: from oblate to per prolate. The findings confirm that morphopollinic traits differ amongst genera of Apocynaceous species. However, these features can be used to distinguish the Apocynaceous taxa. The results show that structural characteristics of pollen and pollinia can help accurately identify Apocynaceous species.
Desired work-leisure balance in a partial equilibrium job search model with multiple job holding
Authors: Sum Lo Simon Ming
Published: December 2023

Work-leisure balances are beneficial to society. A partial equilibrium job search model is developed to explain desired work-leisure tradeoffs for single-job holders and multiple-job holders. Significant work-leisure mismatches are found: 63% of the observations underwork by an average of 17 hours per week, while 37% overwork by 8.5 hours. The value of leisure is approximately four times the average hourly real wage when a single job is held, and it drops by one-third when multiple jobs are held. Models ignoring possibilities of multiple jobholding overstate the elasticity of leisure and understate the value of leisure.

Authors: Csomós György
Published: December 2023

Purpose

This study aims to explore the geography of editors-in-chief to demonstrate which countries exercise the highest-level decision-making in scholarly communication. In addition, the study seeks to investigate the potential relationships between the origin and nationality of academic publishers and the geography of editors-in-chief.

Design/methodology/approach

The analysis involves 11,915 journals listed in Web of Science’s Social Sciences Citation Index (SSCI) and Science Citation Index Expanded (SCIE). These journals employ 15,795 scholars as editors-in-chief. The geographical locations of the institutions the editors-in-chief are affiliated with were identified; then, the data were aggregated at the country level.

Findings

The results show that most editors-in-chief are located in countries of the Anglosphere, primarily the United States and the United Kingdom. In addition, most academic publishers and professional organizations that publish academic journals were found to be based in the United States and the United Kingdom, where most editors-in-chief are also based.

Research limitations

The analysis involves journals indexed in the Web of Science’s SCIE/SSCI databases, which are demonstrably biased toward the English language. Furthermore, the study only takes a snapshot of the geography of editors-in-chief for the year 2022, but it does not investigate trends.

Published: December 2023

The objective is to assess the feasibility, barriers, expectations, and motivation of health trainees in Saudi Arabia regarding medical missions. This study seeks to fill the gap in global health curricula and regulations, as well as provide guidance for trainees participating in international health electives in Saudi Arabia. This cross-sectional survey of health trainees (in medical, surgical, and other allied health professions) was conducted across Saudi Arabia from March 2017 to February 2018 using a standardized survey adapted to assess expectations, barriers, awareness of available opportunities, and the effect of mentorship in improving motivation towards medical missions. A total of 589 respondents completed the survey, with a response rate of 83.7%. Most respondents were under 35 years, with an equal sex distribution. Further, the respondents primarily had medical and surgical specialties training and graduated from the western region of Saudi Arabia. Health trainees who considered volunteering during training but did not have previous experience in missions acknowledged that the presence of a staff member experienced in missions in their training environment positively affected their interest in missions (p= 0.038). The most common reasons for interest in volunteerism were to enhance one's own technical and clinical skills and help others in need. Interest in tourism and learning about new cultures are additional reasons. Only 7/589 participants had experience and expressed the barriers they faced during volunteerism. Interestingly, their colleagues who did not have a similar experience perceived almost the same barriers. A major barrier faced by experienced participants was the "lack of elective time," compared to the "lack of available organized opportunities" by the inexperienced group. In conclusion, coordinating health trainees' missions through a unified authoritative body would provide better opportunities, override challenges, and improve their perceptions and participation in these missions.
Effects of Leek Powder and Sunflower Oil in Guar Gum Edible Coating on the Preservation of Mushrooms (Agaricus bisporus)
Authors: Yazıcıoğlu Nalan
Published: December 2023

This study investigated the effects of various guar gum edible coating formulations, incorporating different proportions of waste leek powder and sunflower oil, on weight loss, color parameters (L*, a*, b* values, and ΔE), texture, and shrinkage of Agaricus bisporus mushrooms during a 7-day storage period. The goal was to assess the potential impact of these coatings on preserving the mushrooms’ quality over time. The results showed that the coatings had a significant effect on reducing weight loss compared to uncoated samples. The lowest weight loss was observed in the 0.5% leek powder and without sunflower oil, while the highest was in 2.5% leek powder and 0.1% sunflower oil. Shrinkage was also positively affected by the coatings, with 1.5% leek powder and without sunflower oil showing the most promising results. The L* values of the coated samples declined slightly, indicating better color preservation, while the a* values exhibited stable redness/greenness. On the other hand, b* values increased, indicating an increase in yellowness during storage. The ΔE values were lower for the coated samples, suggesting less color deviation compared to uncoated ones. Overall, the study indicates that these edible coatings have the potential to maintain the quality of mushrooms during storage, leading to better preservation and extended shelf life.

Effectiveness of Phosphorous acid, Bacillus subtilis and Copper Compounds on Apple cv. Gala with M9 Rootstock in the Control of Fire Blight
Authors: Gür Ayşegül , Baştaş Kubilay Kurtuluş
Published: December 2023

Necrogenic Gram-negative bacterium Erwinia amylovora, which causes economic losses especially in pome fruits such as apple, pear, quince and loquat, some berries and many ornamental plants, causes fire blight disease. Copper compounds are used extensively in disease control programs and they can cause toxicproblems in terms of plant and environmental health. In addition, the formation of resistance to copper in the pathogen is frequently observed. In this study, plant activator phosphorous acid and biological control agent Bacillus subtilis, and 3 different copper compounds,  Copper sulfate,  Copper oxychloride and Copper hydroxide which are commonly  used  against E. amylovora,  on  apple  cv.  Gala  with  M9  rootstock  were  evaluated  comparatively.  When the new season shoot lengths of 3-year-old plants with homogeneous growth reached 20-25 cm, chemicals and B. subtilis were applied first time before one week ago from the pathogen inoculation, and after 2 times with 1 week intervals. The youngest two leaves at tips of actively growing terminal plant shoots were inoculated by cutting off using scissors dipped in suspension of E. amylovora str. EaARADY5 containing 108 CFU ml-1. Disease assessments were made after the disease severity (%)  was determined on the basis of shoot blight after symptom development of the disease stopped, and the results were found to be statistically significant (p<0.05). According to the findings, while the highest effect was obtained by copper oxychloride with 69%  effectiveness among all applications,  the lowest effectiveness was obtained with 43.5% copper sulfate. It has been revealed that the use of the most effective of the copper compounds in field applications will result in less exposure to chemicals in terms of human and environmental health, and that B. subtilis and phosphorous acid can be used significantly in the integrated control of fire blight.

Published: December 2023

Facing a world of continuous, overlapping disruptions, countries are recognizing resilience as the imperative condition for securing a sustainable and inclusive future. For developing countries, such as Costa Rica, Foreign Direct Investment (FDI) has had a positive impact specifically on economic growth, total exports, and the number of people employed. Costa Rica has undergone an important structural transformation in the last three decades, having gone from an import substitution model to a development model oriented to the promotion of exports and attraction of foreign direct investment (FDI). The efforts made to achieve greater international insertion of its economy have allowed the country to diversify its exportable offer, position itself as an attractive destination for investment in search of efficiency, and integrate its exports into global value chains.; ultimately becoming more resilient to external shocks. During the pandemic of COVID-19 Costa Rica’s Investment Promotion Agency (CINDE) reached record numbers in investment projects and job creation, the paper focuses on the years 2020-2021 and the attraction of FDI to the Costa Rica.

In Bokeo province, Lao People’s Democratic Republic, the high rates of poverty and poor health outcomes are striking. According to data collected from the Lao government, the area has a high mortality rate among mothers and children under five years old. Consequently, there is an urgent need for significant enhancements in maternal and child health (MCH) services. This study aims to investigate the perspectives of healthcare providers on the MCH situation, difficulties, challenges, and potential solutions for the growth and implementation of MCH services. We conducted in-depth interviews with 45 healthcare providers from varying healthcare system levels using qualitative methods. The key findings are as follows: Healthcare providers demonstrate a strong understanding of MCH policies, acknowledgment of national objectives, and dedication to personal growth. However, significant obstacles exist, including access barriers for ethnic minorities, transportation complications, inadequate healthcare personnel, and insufficient equipment and infrastructure. Healthcare providers have also indicated a need for more training and opportunities for professional development to improve MCH outcomes. To enhance MCH outcomes in Bokeo province, addressing these challenges and supporting healthcare providers in their quest for self-improvementis essential. The findings of our study can aid in creating targeted interventions and policies to improve MCH outcomes in Bokeo province and similar regions. By focusing on critical areas such as antenatal care, skilled birth attendance, postnatal care, immunizations, nutrition, family planning, health education, and access to healthcare, we can strive towards improved health outcomes and reduced mortality rates.

Published: December 2023

From the mid-1990s, there has been a certain scale of discussion in Chinese academic circles around the concept of mental health. In these conditions, the study of the subjective well-being of Chinese adolescents has gained great importance, which has overall determined the relevance of the research topic. The article is dedicated to the issue of subjective well-being of Chinese adolescents and contains the following research objective - to identify the internal factors of subjective well-being of Chinese adolescents in their relationship with other elements of personality structure. Special attention is paid to studying the influence of activity on the subjective well-being of Chinese adolescents. The diagnostic methods used in the study were: the "Psychological Well-being Scale" by C. Riff, the Proactive Attitudes Scale, and the General Self-Efficacy Questionnaire by R. Schwarzer. The obtained data were analyzed using mathematical-statistical methods (calculation of mean values, standard deviation, Shapiro-Wilk criterion, non-parametric Kruskal-Wallis dispersion analysis, regression and cluster analysis). As a result of the empirical research, it was found that more than half of all surveyed Chinese adolescents have high proactivity, characterized by traits such as initiative, decisiveness, self-confidence, the ability to quickly adapt to changes in the environment, plan, and actively build their future. Thus, adolescents with a proactive behavior model evaluate their subjective well-being higher than adolescents with low activity. The study concludes on the high role of proactivity in shaping the subjective well-being of Chinese adolescents, which can be considered in the development of measures to improve the psychological well-being of Chinese adolescents. The results of the study are consistent with other contemporary research data on mental well-being, the high level of which is ensured by voluntary regulation and proactive activities in educational activities.

Published: December 2023

This study aimed to determine the association between Dietary Diversity Scores (DDS) and nutritional status among adolescent girls with anemia. Seventy-one adolescent girls aged 15−17 years from high schools in Bandung were selected using Probability Proportional to Size (PPS). The data on the sociodemographic characteristics, health and nutritional status, and DDS of the subjects were collected. Results showed that the mean DDS was classified as high. There was no significant association between DDS and BMI-for-age Z-score (BAZ) and Waist-Hip Ratio (WHR) in adolescent girls with anemia (p>0.05). Therefore, DDS was not associated with nutritional status in adolescent girls with anemia.

Published: December 2023

This research aims to evaluate the effect of multiple-micronutrient fortification, baking temperature, and baking time on the sensory acceptance of butter cookies. Unfortified and fortified cookies with 3.2% (w/w) multiple-micronutrient mix were baked with different treatments: 170°C for 15 minutes and 190 °C for 9 minutes. Untrained adult female panelists (n=50) did a sensory test using a 9-point hedonic scale. Interaction between treatments significantly affected texture and aroma (p<0.05). Cookies fortified with micronutrients baked at 190°C had a lower mean hedonic score for texture (5.90±1.91) and aroma (6.54±1.61) among other treatments (p<0.05). These findings indicate that micronutrient fortification and baking profile affect the aroma and texture acceptance of butter cookies.

Authors: Syafiq Ahmad , Fikawati Sandra
Published: December 2023

This study aimed to describe when the effects of the pandemic on food security started to be felt by families in Jakarta (urban area) and Depok (semi-urban area). A cross-sectional survey was conducted among 517 respondents. Data were collected using an online questionnaire. The study revealed that effects of economic decline, reduced purchasing power, and increased food prices occurred early during the pandemic. Those living in semi-urban areas were affected earlier than those living in urban areas. However, more semi-urban families perceived that they were prepared to face food shortage during the pandemic. It is recommended to consider these results for public health nutrition program in food security and disaster.

Published: December 2023

The purpose was to determine the chemical content (water, protein, fat, ash, and carbohydrate) and sensory characteristics of Herbal Chicken Essence (HCE), a functional drink containing chilcken extract, from Indonesia. The experimental design was factorial and completely randomized with two replicates. There are four formulas in this study, namely F1 (broiler chicken and coconut sugar), F2 (broiler chicken and coconut sugar), F3 (IPB D1 chicken and palm sugar), and F4 (IPB D1 chicken and coconut sugar). The chemical content data were analyzed using a two-way ANOVA. Panelists used in the sensory tests included 30 participants. There was a significant effect (p<0.05) of chicken and sugar substitution on water, ash, protein, and carbohydrate contents. Formula 2 (broiler chicken and coconut sugar) is the most preferred in almost all sensory attributes (aroma, taste, mouthfeel, aftertaste, and overall acceptance) because the sour taste found in coconut sugar is able to suppress the fishy taste found in HCE. The substitution of the chicken breed and sugar in the HCE formulations affected the chemical content and sensory characteristics
