The Preliminary Study on the Biology of An Invasive Species, Halyomorpha halys (Hemiptera: Pentatomidae) in Northwest Türkiye
Authors: Özdemir İsmail Oğuz , Doğan Furkan , Tunçer Celal
Published: September 2023

The Brown marmorated stink bug (BMSB) [Halyomorpha halys (Hemiptera: Pentatomidae)] is a polyphagous pest causing significant damage to approximately 300 crops, such as  nuts, vegetables, and ornamentals. In 2017, the BMSB was discovered for the first time in Türkiye. There is currently no published data available on the biology of the pest in Türkiye.  This preliminary study was carried out in Sakarya province, where the BMSB has observed a low population since 2021. In this study, some biological parameters such as voltinism, mortality rates, egg hatching rates, and egg-adult developmental times of the 1st and 2nd generations of the insect populations were determined. The study was carried out under semi-field conditions and laboratory. Considering the BMSB's minimum temperature threshold, which has yet to be determined in Turkey, the accumulation of degree days was calculated using the references to four possible thresholds (DD12, 12.5, 13, 13.5) and was determined to be between 536.91 - 608.69 DD.  The average egg-adult developmental time was 47.85 days for the 1st generation at naturally fluctuating temperatures and 47.13 days for the 2nd generation under laboratory conditions at 25 ֯C. The hatching rate of egg masses was determined to 90.63% in the 1st generation and 57.75% in the 2nd generation. Total mortality in the first generation was 22.97% and 90.24% in the second generation.  It was revealed  that the insect could produce two generations in Türkiye, but the number of egg-producing adults and eggs laid in the second generation was significantly lower than that in the first. This preliminary study was carried out with a limited number of samples due to the initial infesting in the region and,  therefore more comprehensive research is needed to reveal the the biology of BMSB in the country.

Microplastics are a growing concern in the environments and especially agricultural soil due to numerous negative impacts on the ecosystems and human health. This study aimed to investigate the properties of microplastics (including quantity, shape, size, and polymer types) in five samples (DA1-5) taken from agriculture soil in Dong Anh district, Hanoi using Nicolet iN10 MX Fourier transform infrared (µFTIR) microscope. The study found that the microplastic content in these soils ranging from 494 ± 292 items/kg dry weight to 1031 ± 379 items/kg dry weight. In terms of shape, microplastic fragments accounted for the majority of microplastics found in soil (65% - 86% of the total microplastics). Fifteen types of microplastic polymers were identified in the soil samples, with PET being the most common polymer of 38%, followed by urea-formaldehyde resin of 15%, and nylon of 13%. Microplastics with sizes ranging from 50-150 µm were the dominant group (39% - 57% of the total microplastics). This study provides an initial assessment of the presence of microplastics in the agricultural soil of the suburban area of Hanoi, highlighting the potential risk of contamination that may effect on environment and pose a threat to human health.

Published: September 2023

Photovoltaic (PV) temperature is an important parameter that can influence PV performance. The increase in PV temperature can cause a drop in PV output voltage, which indicates that the PV does not operate optimally. In this paper, a design of an integrated cooling system based on fuzzy logic to control the PV temperature is presented. This, in effect, will potentially ensure that the PV performance is at its maximum condition. In this work, the temperature of the PV is kept constant by attaching a cooling system that carries water inside it. The constant temperature of the cooling system is carried out through a radiator and thermoelectric with electronic control. The experiments are carried out using two 320-watt PV systems; one with the cooling mechanism and the latter without the cooling system as a control. Several important data such as temperature, voltage, current, and radiation measurement in each PV were collected for three days from 10:00 to 17:00 with an interval of 10 minutes for each measurement. The results of the integrated cooling system measurement showed an increase in PV power generation and efficiency of 1.32% compared to the control PV unit. From the results of the study, it can be concluded that the fuzzy logic-controlled cooling system contributed to the increase in PV performance.

Published: September 2023

Today, scientists are interested in the manufacturing and invention of smart textiles such as phase change materials (PCMs). The process of phase change from solid to liquid and vice versa takes place in such materials. Using materials such as PCM could change the properties of leather for better performance, and could be applied to many places such as the shoe industry. The background of the study is that using PCMs could increase thermoregulating properties of materials. For finishing leather with PCMs, several methods were suggested such as spraying, tanning, laminating, etc. In this study, first impregnated leather with 5% and 10% of PCM by spray technic are prepared and characterized using scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). Finally, water vapor permeability and physical properties of the samples were analyzed for an understanding of leather comfort. The results reveal that after impregnating with 10% PCMs, significant effects on the thermal behavior of samples were observed, and this finishing had no effect on the comfort of leather.

The role of workplace friendship in cultural intelligence and quality of work-life: A cross-sectional study
Authors: Babalola Sunday Samson , Nwanzu Chiyem Lucky
Published: September 2023

The purpose of this study is to examine the effect of cultural intelligence (CI) and workplace friendship (WPF) on the quality of work-life (QWL) of individual workers and to examine whether WPF mediates the relationship between CI and QWL between employees of the same nationality, but of different ethnic groups working in government-owned organisations. A cross-sectional study was conducted among 161 employees using self-report measures. Data analysis was performed using two statistical procedures (the Harman single factor test and the correlation matrix) to assess the presence of a common-method variance (CMV) bias in the data collected for this study. Theoretical propositions and empirical observations offered plausible explanations for WPF's mediating role in the CI-QWL relationship. The present study confirms the reliability and, to some extent, the validity of the measures in a developing economy context. However, this study also builds empirical evidence that age and gender are fewer differentiating factors in employees' work attitudes and behaviour.

Published: September 2023

The Turing Test is a method of testing whether a machine has human intelligence. A novel brain–computer interface (BCI) Turing Test was proposed in the BCI Controlled Robot Contest in World Robot Contest 2022. Contestants developed algorithms that can distinguish if an instruction is issued by a human. Participants collaborated with an electroencephalogram-based BCI to play a soccer game in a virtual scenario. Participants were asked to perform steady-state visual evoked potential (SSVEP) tasks or motor imagery (MI) tasks to control the robots or be in an idle state to mimic the system giving instructions on behalf of the participants. Several algorithms proposed in this competition are developed based on the concept that the idle state is a category in multiclass classification problems. This paper details the algorithms of the top five teams with the best performance in the final, lists the popular classification models and algorithms for MI and SSVEP, and discusses the effectiveness of each approach in improving classification performance and reducing the computation time.

Determining the location of bank branch offices is a policy that must be taken to respond to challenges and changes in the long term, so an in-depth analysis is needed to choose the right location. Ranking is done based on the weight of the sub-criteria that have been processed using the Fuzzy Analytic Network Process (FANP) method. Weight calculations are also based on dependencies, both inner and outer dependencies. The existence of interrelationships between sub-criteria with one another makes the Fuzzy Analytic Network Process (FANP) method more complex than other decision-making techniques. Based on the calculation of the Fuzzy Analytic Network Process (FANP) method, the weight of each sub-criteria is obtained, namely the population of 8.62%, population density of 12.95%, land area of 4.65%, security facilities of 24.65%, availability of public utilities of 2.62%, location distance to settlements of 12.53%, the closest distance between fellow branches of 33.09%, and the number of competitors of 0.90%.

Authors: APRILIA AJENG DIVA , Sofro A'yunin
Published: September 2023

The number of confirmed cases of malaria in East Java from 2020 to 2022 is a count data with numerous zero values and is exhibiting overdispersion. With Zero Inflated Poisson (ZIP) regression, this work seeks to solve the overdispersion issue that plagues Poisson regression. The ZIP model is superior to the Poisson regression model, according to the results. Data modeling with ZIP regression carries out model fit testing with the G test, parameter significance testing with the Wald test, and parameter estimation using Maximum Likelihood Estimation. For case data of malaria positivity, the ZIP regression model in this research is log(𝜇𝑖) = 3,695 + 0,0057X1 − 0,0569X2 − 0,0085X3 − 0,0619X4 + 0,0604X5 − 0,0118X6 − 0,012X8, and logit(𝜔𝑖) = −5,5185 + 0,0039X2 − 0,592X6. The test's findings indicate that factors such as population density, poverty levels, the proportion of households with access to clean water and sanitation, the morbidity rate, the number of medical facilities, the number of health complaints, and the percentage of public spaces that adhere to health standards all significantly influence the number of confirmed cases of malaria in East Java.Keywords: Malaria, excess zeros, overdispersion, Zero Inflated Poisson.

Published: September 2023

Kucing adalah salah satu hewan mamalia karnivora yang banyak dipelihara oleh manusia. Sifatnya yang mudah beradaptasi dengan manusia menjadikan kucing memiliki hubungan yang erat dengan pemiliknya. Cara kucing menyampaikan pesan yaitu dengan mengeluarkan suara yang identik dan beberapa dari suara tersebut mencerminkan kondisi kucing. Akan tetapi, kategorisasi suara-suara kucing merupakan tantangan yang besar karena beberapa suara sangat mirip dengan yang lain dan kucing dapat menghasilkan suara yang berbeda dalam perbedaan waktu yang sangat kecil. Hal ini yang membuat si pemilik kucing sulit mengartikan dan memahami kondisi kucingnya. Dengan menggunakan dimensi fraktal dapat dilakukan analisis suara kucing sesuai kondisinya. Pada penelitian ini akan diklasifikasikan kondisi kucing berdasarkan suara menggunakan dimensi fraktal Higuchi dan K-Nearest Neighbor (KNN). Data yang digunakan yaitu 80 data suara kucing dengan kondisi angry (marah), fighting (berkelahi), happy (senang), huntingmind (berburu), mating (kawin), paining (sakit), resting (istirahat), dan warning (peringatan). Tahapan awal yang dilakukan yaitu proses Pre-Processing, kemudian ekstraksi ciri menggunakan Discrete Wavelet Transform dengan tipe mother wavelet Daubechies 4 dan dekomposisi 5 level. Selanjutnya akan dicari nilai dimensi fraktal dengan metode Higuchi. Setelah diperoleh nilainya, data dibagi menjadi 2 yaitu data training dan data testing. Selanjutnya diklasifikasikan menggunakan algoritma KNN dengan percobaan nilai K yaitu 1, 3, 5, 7, dan 9. Dari penelitian ini diperoleh akurasi tertinggi sebesar 87,5% dengan nilai K-max pada metode Higuchi adalah 60 dan K pada KNN adalah 9. Hal ini menunjukkan bahwa metode Higuchi dan KNN dapat diterapakan dalam klasifikasi kondisi kucing berdasarkan suara.

Background: Healthcare-associated infections (HAIs) continue to pose significant challenges to patient safety and healthcare systems worldwide. Poor hand hygiene among healthcare professionals remains a major contributing factor to the spread of HAIs. Despite its importance, hand hygiene compliance among healthcare workers, including medical students, remains low. Training programs to improve hand hygiene knowledge and compliance have been implemented globally. This study aimed to assess the impact of a hand hygiene training program on medical students at Burdwan Medical College & Hospital in West Bengal.

Methodology: A cross-sectional study was conducted involving 122 Professional MBBS students who were selected through purposive sampling. Written informed consent was obtained from each participant. The students' baseline hand hygiene knowledge was assessed using the WHO questionnaire before providing hand hygiene training. Post-training, the same questionnaire was used to evaluate the level of knowledge acquired. The data were analyzed using the student t-test to determine the statistical significance of the training program.

Results: The mean pre-test score was 11.24±5.29, while the mean post-test score significantly increased to 17.34±5.4 (p<0.001, 95% CI). This finding indicates a substantial improvement in hand hygiene knowledge among medical students after undergoing the training program.

Conclusion: Regular and frequent training programs on hand hygiene, accompanied by monitoring and timely feedback, are crucial for increasing awareness and compliance among medical students. It is essential for medical colleges to establish an Infection Prevention and Control Committee to organize and oversee such training initiatives, which play a pivotal role in mitigating the risk of HAIs.
Analysis of psychophysiological strain in response to endurance exercise in military personnel.
Authors: Huma Bugti  , Faizan Mirza
Published: September 2023

Background: During exercise, athletes experience a significant elevation in physiological strain, influenced by a multitude of internal and external factors, including physical and environmental conditions. These factors dictate how different organ systems respond to physical activity. This study aims to investigate the psychophysiological strain reactions to endurance training in military male runners.
Methodology: A cohort of 75 male military runners, engaging in daily 90 minute exercise routines and aged between 20 and 30, was recruited for the study. The study assessed various physiological variables in military runners, encompassing lactate threshold (LT), maximum oxygen uptake (VO2 max), and percentage heart rate reserve (%HRR). Additionally, psychological assessments were conducted using the Brunel Mood Scale and Borg's Rate of Perceived Exertion.
Results: The findings revealed a gradual increase in heart rate (HR) and VO2 max as running intensity escalated. Notably, the runners' perceived exertion rate rose following competitive running events, concomitant with a decrease in their positive mood scale ratings. This trend reflected their disappointment stemming from their performance outcomes.
Conclusion: The study highlights that VO2 max and LT serve as robust indicators of male runners' potential. Furthermore, the evaluation of runners' mood and perception of exertion before and after the sprint demonstrated an augmentation in negative emotions post-exercise.

The levels of double-strand DNA breaks as a severe disruption of genome integrity were studied using the neutral version of the comet assay in the sperm samples of the men of the Belarusian population with normozoospermia and pathozoospermia, including asthenozoospermia, oligozoospermia, oligoasthenozoospermia, and other combined forms of pathozoospermia. It was demonstrated that double-strand DNA breaks have a large proportion (about 44–50 % on average) of the total number of DNA damage (singleand double-strand breaks, alkaline-labile sites, etc.) analyzed with the alkaline version of the comet assay recommended by the World Health Organization. Higher levels of sperm double-strand DNA breaks were established in the pathozoospermia group and in asthenozoospermia subgroup compared to the normozoospermia group. It was also shown that the levels of double-strand breaks observed at pathozoospermia correspond to the mutagenic effect in vitro of high concentrations (10–30 μg/ml) of bleomycin sulfate that acts as a strong radiomimetic, which points to a significant disruption of the DNA integrity at pathozoospermia. In general, the data obtained demonstrate the usefulness of the sperm double-strand DNA break analysis for male infertility diagnostics.

Published: September 2023

The article presents the computer simulation results for the stress-strain state of the lining sections of the shaft No. 1 of mine 3 of JSC Belaruskali that were obtained using visual and instrumental investigation of the mine lining state. The loading parameters of the shaft take into account the specific feature of the lateral pressure calculation in the considered location. This means that the shaft intersects vertically rocks different in their physical and mechanical properties. Computer simulation of loading of the most problematic vertical mine shaft sections observed by the lining examination results was performed using the Static Structural component of the ANSYS Workbench engineering software package. Distribution diagrams of longitudinal normal, shear and von Mises equivalent stresses in the vertical mine shaft lining are obtained for the design and residual values of the cast-iron tubing thickness. A comparative analysis of the mine shaft residual bearing capacity for various parameters of the lining elements was carried out. Based on the computer simulation results, the conclusions were made on the bearing capacity of the shaft No. 1 of mine 3 of JSC Belaruskali and the recommendations for a further safe operation of the mine shaft were suggested.
Profile of pro- and anti-inflammatory cytokines during injection of fatty acid amides with ethanolamine and glycine in modeling peripheral neuropathy
Authors: Doronkina A. S. , Zhavoronok I. P. , Bogdan V. G.
Published: September 2023

The effect of fatty acid amides during the blockade of membrane orphan GPR18, GPR55 and nuclear PPARα receptors on the level of pro- and anti-inflammatory cytokines in rats with experimental peripheral neuropathy was studied. It has been proven that the anti-inflammatory action of PEA and SEA in experimental animals with neuropathy is carried out through nuclear PPARα receptors. However, PGlyA has no anti-inflamatory effects in a rat model of peripheral neuropathy.

The inflammatory process specific for chronic obstructive pulmonary disease (COPD) is accompanied by T lymphocyte migration from peripheral blood to the respiratory tract. Suppression of T cell chemotaxis by drugs may attenuate the inflammatory response in patients with COPD.

The aim of this study was to determine the ability of azithromycin in combination with glucocorticoids to affect the migration of blood T cells in patients with COPD.

The percentage of T lymphocytes expressing chemokine receptors CCR5, CCR6, CCR7, CXCR3, CXCR4, CXCR6 was analyzed by flow cytometry in the peripheral blood of 54 smokers with COPD, 21 healthy smokers, and 20 healthy non-smokers, as well as in bronchoalveolar lavage (BAL) of 7 smokers with COPD and 7 healthy smokers. Additionally, we determined the effect of azithromycin (10 μg/ml) and budesonide (10 nM) on the migration of peripheral blood T helper cells and cytotoxic T lymphocytes from patients with COPD (n = 8) to chemokines RANTES (10 nM) and IP-10 (10 nM).

The percentage of T lymphocytes expressing chemokine receptors CXCR3 and CCR5 increased in the peripheral blood of COPD smokers compared with healthy smokers and healthy non-smokers, as well as in the BAL of COPD smokers compared with healthy smokers. The proportion of T cells expressing chemokine receptors CXCR4, CXCR6, CCR6, and CCR7 did not differ in the peripheral blood and the BAL between COPD patients and healthy controls. Budesonide only inhibited the migration of cytotoxic T lymphocytes to RANTES. Azithromycin, alone and combined with budesonide, inhibited the migration of T helper cells and cytotoxic T lymphocytes to both RANTES and IP-10. Moreover, the inhibitory effect of azithromycin, in combination with budesonide and without it, on the T cell migration was significantly greater than the effect of budesonide alone.

Our results suggest a role for CXCR3 and CCR5 in T cell recruitment into the lungs of COPD patients and demonstrate the ability of azithromycin to inhibit T lymphocyte migration.

This study aims to determine whether integrated reporting has a positive impact and whether textual risk disclosure (TRD) negatively impacts the company's market value. Signaling theory is used in this study, which focuses on how integrated reporting and TRD provide positive signals to investors so that they can increase firm value. Purposive sampling was used when the samples were mining companies listed on the Indonesia Stock Exchange (IDX). There are 168 observations and 56 firms in the sample. Stata 14.2 is used to analyze and multiple regression to test the hypothesis. As a result, integrated reports and Textual Risk Disclosures (TRD) do not affect the company's market value. This research has implications for stakeholder policies where other factors such as financial performance, industry stability, and other macroeconomics are more dominant in influencing company value. Companies can consider increasing the quality and relevance of their risk disclosures to provide more helpful information for investors.
