The Relationship between Green Human Resource Management Practices and Organizational Citizenship Behavior
Authors: Mostafa Bassant Adel , Saleh Reham Saber
Published: March 2023

In an era of green environmental awareness, Green Human Resources Management (GHRM) uses human resources management practices to support green environmental functions. It embraces green environmental concerns by applying human resources initiatives to generate high performance and better efficiency in operations. Although the literature on GHRM is growing, a few studies investigated to what extent green innovative culture (GIC) moderates the relationship between green human resources management practices and organizational citizenship behavior towards the environment (OCBE). To address this research gap, the authors tested a new conceptual framework investigating the direct and interactive effects of GHRM practices and GIC on OCBE. A quantitative study uses a survey from a 174 convenient sample of employees selected from a manufacturing firm operating in Egypt. The research results revealed that (1) GHRM practices are crucial for encouraging employees to engage in green activities, in addition (2) there is a significant positive effect of GHRM practices on OCBE, while on the other hand, (3) the interaction of GHRM and GIC can foster employees’ engagement in OCBE. The research significance lies in identifying and validating the GHRM practices applied in the manufacturing firm, as it advances the previous studies by developing a research model that offers critical insights on how manufacturing organizations working in industrial and agricultural packaging solutions could strategically link their GHRM practices and green innovative culture to support their OCBE in creating a competitive advantage in the market.
The Role of Spousal Support in Working Mothers’ Work-Life Balance
Authors: Alarifi Areej , Basahal Abdulrahman S.
Published: March 2023

This paper studied how Saudi working mothers experience spousal support, and what types of support are most relevant for them. Drawing on a qualitative research design with 17 semi-structured in-depth interviews with Saudi working mothers, and a thematic analysis approach, this study explored and discussed in-depth six types of spousal support and how working mothers experience each. We find that the most relevant and welcomed type of support is professional support, especially as it relates to current and future career aspirations, followed by more practical support in the household and with childcare/parenting responsibilities. Intellectual and emotional support are appreciated, but not a must, as most women feel they should be able to deal with their own emotions without their husband’s involvement. Financial support is becoming less relevant and the least-needed type of spousal support. Overall, we find that most working mothers struggle to find a balance between their work and non-work-related life, and male partners have an essential role in helping their wives find that balance.

Impact of The Fourth Industrial Revolution on Vietnamese Legislation on Female Employment Law: The Issues Raised in Improving the Law Governing the Employment of Female Workers
Authors:   Soc Trang Provincial Political School, Viet Nam, Anh Pham Van
Published: March 2023

The Fourth Industrial Revolution (4IR) influences all aspects of global life, including the employment of female workers. The problem of creating jobs for female workers is becoming increasingly difficult due to the fiercer competition on the job market as a result of the influx of foreign workers into the national market, the increased demand for skilled labor, and the substitution of artificial intelligence (AI) and robots for low-skilled jobs. The Industrial Revolution 4.0 has a significant impact on the job market of female workers due to its technological characteristics, such as the unemployment of female workers in a number of new occupations and their lack of adequate skills. In order to ensure sustainable employment for female workers, the completion of the law on the employment of female workers is a necessary and objective concern for every nation, including Vietnam calling for special consideration. Consequently, the paper focuses on elucidating the current state of Vietnam's law on female employment as well as the effects of the Fourth Industrial Revolution on the improvement of Vietnamese legislation on female employment. The author proposes some improvements to the law governing the employment of female workers in the near future.

Authors: SINGTHANU Seksan , SURIN Prayoon , NILSONTHI Thanasak , PIPATTHATTAKUL Manop
Published: March 2023

In the hot-rolling process, steel was subjected to high temperatures which results in the formation of an oxide layer called scale. The oxide scale can be affected to the surface characteristic of the hot-rolled steel product. The scale must be completely removed from the surface of the steel before further processing. This research aimed to examine the adhesion behavior of scale on hot-rolled steel with different silicon contents (0.01, 0.12, 0.18, and 0.29 wt%) using a tensile testing machine with an observation setup. The results showed that the scale thickness decreased with increasing silicon content in the range of 9 µm to 12 µm. The scales were composed of hematite and magnetite. The results of the tensile test showed that the strain initiating the first spallation and the mechanical adhesion energy tend to increase with increasing silicon content. However, it decreased by 0.29 wt% Si hot-rolled steel. This result indicates that scale was difficult to remove after the hot rolling process for higher Si-containing steel.

Authors: SHARMA Bhawana , ALAM Afroz
Published: March 2023

The current research work explores the production of silver nanoparticles using aqueous extracts of Delonix regia (Boj. ex Hook.) Raf. (Angiosperms; Fabaceae) shoots for the bioreduction of Ag metal and its antimicrobial activity. Fourier transform infrared spectroscopy (FTIR), Zeta potential, ultraviolet-visible spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD) have been used to evaluate the produced silver nanoparticles (AgNPs). Both antibacterial and antifungal activity were examined against bacterial and fungal pathogens, viz., Escherichia coli and Bacillus subtilis, and fungal strains, viz., Fusarium oxysporum and Aspergillus niger. The presence of silver nanoparticles was observed by the color change, i.e., from pale yellow to dark brown. The zeta potential observed for the produced nanoparticle is -18mv. The SEM and XRD revealed the size of synthesized AgNPs, i.e., 35nm and SEM size lies in the range of 40-60 nm. UV-visible absorption spectra were found at wavelength 425 nm. The synthesized nanoparticles are cost-efficient and could be an alternative procedure for the peculiar production of nanoparticles and also act as potential antimicrobial agents.

Published: March 2023

The cactus (Opuntia ficus-indica (L.) Mill.) belongs to the Cactaceae family and it’s used in traditional folk medicine in treating a number of diseases and conditions. Due to the remarkable biological activity and to the bioactive (phytochemicals) compounds of O. ficus-indica, it becomes the aim of many research studies. The current study aimed to evaluate the analgesic activity of various solvent fractions (aqueous and ethanol) prepared from the O. ficus-indica flowers. The centrally analgesic potential was evaluated using tail flick latency in tail immersion and hot plate methods in mice. Morphine was used as a positive control at a dose of 3 mg kg-1, s.c.. Intra-peritoneal administration of the aqueous extract of O. ficus-indica flowers at the highest dose did not produce any toxicity symptoms, thus the median lethal dose (LD50) was estimated to be greater than 2,500 mg kg-1. The results of the pain behavior evaluation according to the gender approach of mice showed that the pain tolerance threshold is high in males compared to females. We found that various plant extracts at doses of 300, 500, and 1,000 mg kg-1 i.p., displayed significant and dose-dependent protective effects (p < 0.01, p < 0.001, and p < 0.0001) as measured by increased latency time compared to vehicle control. The maximum anti-nociceptive effect was with the ethanol extract (71%) at 60 minutes at a dose of 1,000 mg kg-1, which was equivalent to the effect of morphine (70%). The results suggested that O. ficus-indica might possess significant analgesic effects, supporting the use of this plant in traditional medicine.

Published: March 2023

In Nigeria, Chromolaena odorata (L.) R. M. King and H. Rob and Tithonia rotundifolia (Mill.) S. F. Blake, are exotic invasive weeds, but a gradual decrease in the population of C. odorata with the rapid invasion of T. rotundifolia is now observed. Therefore, this study investigated the adaptive features of each weed in competition, with a further determination of seedling recruitment from the soil seed bank of plots invaded by T. rotundifolia. Field sampling was carried out in 10 plots: T. rotundifolia invaded plots and low or uninvaded plots in co-existing with other plants using 10 m x 10 m quadrats. The readily germinable seed species composition and the Sorensen index of similarity between the seed bank and their above ground vegetation were determined. Competition Series Experiment was also conducted for the two plants. Mariscus alternifolius (227) and Oldenlandia corymbosa (358) were the most abundant species in the seed bank while T. rotundifolia recruited 25 individuals. Low similarity index existed between the seed bank and the standing vegetation of the invaded and uninvaded plots. T. rotundifolia had improved growth in heteroculture with C. odorata over when in monoculture. However, a reduction in growth of C. odorata occurred when in competitive association with T. rotundifolia compared to when in monoculture. T. rotundifolia had competitive advantage over C. odorata.

Crateva adansonii (CA) is traditionally used in the treatment of epilepsy and memory loss. This work aims to evaluate the antidepressant and anxiolytic activities of the dichloromethane/methanol extract of CA trunk bark in a chronic unpredictable stress-induced depression (UCMS) model in mice. After exposure of mice to UCMS for 42 days, anhedonia was assessed using the sucrose preference test, antidepressant effects by the forced swim and caudal suspension tests, anxiolytic effects by the light/dark compartment (LDB) and open arena (OF) tests. Oxidative stress parameters Malondialdehyde (MDA), Superoxide Dismutase (SOD), Catalase (CAT), and Reduced Glutathione (GSH) were assessed. The results showed that multiple administrations of C. adansonii extract (150 and 300 mg/kg, resulted in a significant increase from 38.5% to 64.9% (p<0.001) in sucrose intake and a decrease from 47 seconds to 14 seconds in the immobility time in the forced swim test compared to the UCMS group. The extract significantly (p<0.001) reversed the time spent in the dark box at 150 mg/kg, and the number of groomings at 150 and 300 mg/kg compared to the UCMS group in the LDB and OF test. There was also a significant (p<0.001) improvement in SOD, GSH, and a reversal of MDA. The extract of CA improved symptoms of depression and anxiety in mice treated with different dose. The effects observed would be due to the presence in the extract of polyphenols such as flavonoids. These effects would justify the use of this extract in traditional medicine.

The direct electrochemical conversion of ethanol, a sustainable fuel, is an alternative sustainable technology of the future. In this study, membrane electrode assemblies with different electrode configurations for an alkaline direct ethanol fuel cell were fabricated and tested in a fuel cell device. The configurations include a catalyst-coated substrate (CCS), a catalyst-coated membrane (CCM), and a mixture of these two fabrication options. Two different anion exchange membranes were used to perform a comprehensive analysis. The fabricated CCSs and CCMs were characterized with single cell measurements, electro­chemical impedance spectroscopy and scanning electron microscopy. In addition, the swelling behavior of the membranes in alkaline solution was investigated in order to obtain information for CCM production. The results of the experimental electrochemical tests show that the CCS approach provides higher power densities (42.4 mW cm-2) than the others, regardless of the membrane type.

Travelling Salesman Problem with profits (TSPP) is a special case of the general Travelling Salesman Problem, all nodes must not be visited, but profit is collected from visited nodes. It is a well-known NP-hard combinatorial optimization problem in the literature. Because of the problem's complexity, exact methods cannot find the global optimum solution to this problem, so many heuristic and metaheuristic solution techniques are studied to find a feasible solution in a reasonable time. In this research, two different metaheuristic algorithms, Simulated Annealing with Many-moves and Variable Neighborhood Search, are proposed to solve the TSPP. Proposed algorithms are tested with three different problem instances and compared in terms of the efficiency of algorithms.

Published: March 2023

With the rapid increase in population in the world, people's demands for chilled and frozen foods are also increasing. The healthy and energy efficient cold storage of foods has become an important issue. In this context, studies on the efficiency and performance of energy management models including automatic control techniques on cooling systems have been investigated in recent years. The purpose of this study is to give information about faults, traceable energy management models and control systems in the perspective of cooling systems.

Maintenance of cooling systems, malfunctions and their late detection cause time and cost problems. The decrease in the performance of the cooling system or the occurrence of malfunctions cause economic costs as well as energy consumption. Controlling the changes in pressure, temperature and electricity consumption values ​​in cooling systems and comparing them with standard operating conditions is one of the methods used for fault detection. Faults that may occur in cooling systems; compressor, condenser, evaporator, expansion element and fan failures, thermal failures, phase protection relay failures, under/over refrigerant charge, probe failures, night curtain electric motor failure, condenser-evaporator surface pollution. Errors and malfunctions occurring in the cycle cause the parameters under normal operating conditions and accordingly the cooling performance coefficient to change. Traceable energy management models are needed to detect faults and prevent them in a short time. With the design and implementation of these models, long-term damage to the system is prevented by reducing energy, maintenance and repair costs.

In the design of traceable energy management models and control systems for cooling systems; set point and management, alarm notification and management, designing algorithms with precise temperature control will provide energy efficiency.

This topic isground-breaking, as space law (without a definition of space object or space drone) is attempting tokeep up with the evolving space technology.The design and construction of space drones may be used to study Mars, Venus and other celestialbodies. These first two planets were studied well in the 20th Century; for example, the atmosphereof Venus was explored by two balloons. A few years ago, the concept of using UAVs in spacemissions appeared. On April 19, 2022, a successful experiment was carried out with the first smallMars space drone Ingenuity; it took ten photos (of the crashed lander), which were sent to thePerseverance rover, and through it to the Earth. Larger space drones are currently being developed;one of the projects concerns a platform for launching spacecraft from a height of 18 km above theEarth, and another assumes the use of nuclear propulsion in space drones.However, it appears that the law is unable to keep up with evolving space technology. Plans for theuse of space drones may face many difficulties due to the imprecision or loopholes of internationalspace law and the need to rely on soft law, i.e. regulations and recommendations whose adoptiondepends on the goodwill of states. Besides, using analogy to unmanned aerial vehicle regulation(EU, ICAO) may not prove to be always possible. What is more, there is a scarcity of literature andlack of legislation on space drones, which is a challenge for international lawyers. Aviation law andaviation organizations taking care of UAVs are good examples to be followed by space legislators.

La anemia es una condición que afecta principalmente a mujeres gestantes, en edad fértil y a niños menores de cinco años. La anemia por deficiencia de hierro es la más prevalente y ocasiona desventajas a nivel cognitivo, económico, de salud, entre otros. En las gestantes con dicha condición, existe un mayor riesgo de dar a luz un neonato con bajo peso o prematuro, y aumenta el riesgo de mortalidad perinatal y neonatal. La anemia durante la gestación es diagnosticada cuando la hemoglobina es menor a 11g/dl en zonas geográficas ubicadas por debajo de los 1000 m s. n. m. Sin embargo, en el segundo trimestre del embarazo, entre las semanas 13 y 28, el diagnóstico de anemia se realiza cuando los valores de hemoglobina están por debajo de 10,5 g/d.
Role of the uric acid/albumin ratio in predicting mortality of patients who underwent transcatheter aortic valve implantation
Authors: Levent Fatih
Published: March 2023

Objectives: The aim of this study was to investigate whether baseline uric acid/albumin ratio (UAR) was a predictor for mortality in patients who underwent transcatheter aortic valve implantation (TAVI) due to severe aortic stenosis. Patients and methods: The retrospective study included 240 patients (121 females, 119 males; mean age 77.5±7.6 years; range, 52 to 95 years) who underwent TAVI between January 2015 and January 2020 in two centers. Patient characteristics were compared between two groups according to mortality during follow-up (the mortality group and the survival group). The value of the UAR in predicting mortality was evaluated with receiver operating characteristic curve analysis. Predictors of mortality after TAVI were investigated with Cox regression analysis. Results: In-hospital mortality developed in 16 (6.7%) patients, and postdischarge all-cause mortality was observed in 41 (17.1%). The two-year mortality rate was determined to be 15%. The rate of systolic heart failure, systolic pulmonary artery pressure, and UAR were found to be significantly higher in the mortality group (p=0.007, p=0.036, and p<0.001, respectively). The diagnostic power of UAR in predicting mortality was poor (the area under the curve=0.671, confidence interval [CI]: 0.589-0.753, p<0.001). Independent predictors of mortality after TAVI were UAR >2.03 (hazard ratio=2.958, CI: 1.623-5.393, p<0.001) and platelet count (hazard ratio=0.996, CI: 0.992-1.000, p=0.05). Conclusion: Uric acid/albumin ratio was found to be an independent predictor for short-and long-term all-cause mortality in patients who underwent TAVI.
Radiofrequency ablation versus high ligation and stripping for the treatment of symptomatic great saphenous vein insufficiency: Short-term patient-reported outcomes
Authors: Topcu Ahmet Can
Published: March 2023

Objectives: The study aimed to compare short-term patient-reported outcomes of radiofrequency ablation (RFA) versus high ligation and stripping (HLS) in a cohort with symptomatic great saphenous vein (GSV) insufficiency. Patients and methods: This was a single-institution, retrospective, observational, cohort study of prospectively collected data. All procedures were performed between January 2019 and February 2021. Ninety-seven patients (54 females, 43 males; mean age: 45.2±11.1 years; range, 18 to 76 years) with lower limb chronic venous disease symptoms refractory to exercise, compression stockings, and pharmacotherapy underwent RFA (n=60) or HLS (n=37). Self-reported pain assessment was performed on the first postoperative day using the numeric rating scale, and duration of return to daily activities was questioned on the 30th postoperative day. Results: Patients in the RFA group reported significantly less pain compared to patients in the HLS group with median numeric rating scale scores of 1.5 (0-4) versus 4 (2-5), respectively (p<0.001). The RFA group returned to their daily routine significantly sooner compared to the HLS group (1 [1-1] versus 1.5 [1-4] days, respectively; p=0.004). Conclusion: Radiofrequency ablation is associated with significantly less postoperative pain and earlier return to daily activities compared to HLS in patients with symptomatic GSV insufficiency.
Does final intraoperative endoscopic control increase surgical success in conventional septoplasty?
Authors: Yurtsever Kum Nurcan
Published: March 2023

Objectives: This study aimed to investigate the effects of the final endoscopic control performed intraoperatively in conventional septoplasty on operative time, residual deviation, and changes in Nasal Obstruction and Septoplasty Effectiveness Scale (NOSE) scores. Patients and Methods: One hundred twenty-five patients who applied with the complaint of nasal obstruction between June 2020 and May 2021 and were found to have isolated nasal septum deviation were evaluated in this prospective study. Patients with comorbidities were excluded from the study. Remaining 80 patients (55 males, 25 females; mean age: 30.1±8.9 years; range, 18 to 58 years) included in this study. The patients were divided into two groups of 40 individuals using the blocked randomization method. In the first group (CS-EC group; 26 male, 14 female; mean age: 31.7±8.3 year; range 18 to 58 year), after conventional septoplasty with head light, additional pathologies were corrected with the conventional method if it was detected by the endoscope. For the second group (CS group; 29 male, 11 female; mean age: 28.6±9.3 year; range 18 to 53 year), only conventional septoplasty was performed. The patients were evaluated with NOSE before and three months after the operation to evaluate the complaint of nasal obstruction. The groups were compared in terms of NOSE scores, operation time, and postoperative residual deviation. Results: The mean operation times in the CS-EC and CS groups were 44.9±9.3 and 39.0±7.7 min, respectively, and this difference was statistically significant (p=0.001). While there was no statistically significant difference between the CS-EC and CS groups in terms of preoperative total NOSE scores (p=0.211), the postoperative total NOSE score was found to be statistically significantly lower in the CS-EC group compared to the CS group (p=0.001). Conclusion: Final intraoperative endoscopic control of the nasal passage in classical septoplasty may be an effective method to detect septal deviations that cannot be adequately evaluated.

Malignant catarrhal fever (MCF) is a serious, usually fatal disease affecting many species of ungulates of the subfamily Bovinae and family Cervidae including pigs and caused by a herpesvirus under the genus Macavirus in the subfamily Gammaherpesvirinae. Ten Macaviruses have been identified to date and 6 were found to be associated with clinical MCF. Alcelaphine herpesvirus 1 (AlHV-1), which causes inapparent infection in wildebeest and ovine herpesvirus 2 (OvHV-2), which is associated with subclinical infections in sheep are the two most important herpes viruses that cause clinical wildebeest associated MCF (WA-MCF) and sheep-associated MCF (SA-MCF), respectively. The disease is characterized by accumulation of lymphocytes (predominantly CD8+ T cells) in a variety of organs, often associated with tissue necrosis. AIHV-1 can be recovered from animals, while OvHV-2 has never been recovered from affected animals, only OvHV-2 specific DNA is detected in cultured lymphoblastoid cells from infected animals. Diagnosis is normally achieved by observing the clinical signs, characteristic histopathological changes, ELISA and detection of viral DNA in the infected animals. Detection of viral DNA by PCR is becoming the method of choice for diagnosing the SA-MCF. Currently, there is no effective disease control measure. Attenuated AlHV-1 virus vaccine has been developed with varying degree of success for control of WAMCF in Africa. Separation of reservoir host from susceptible host or raising of OvHV-2 free sheep is the only solution for control of SA-MCF. In India, our group first confirmed SA-MCF in Kashmir. The present article updates current epidemiology, diagnosis, prevention and control of MCF with special reference to India.

Toll like receptors (TLRs) expressed by various immune cells and tissues are known to play an important role in recognising the pathogens by the host. The study was carried out to envisage the expression of virus-recognising-TLRs like TLR-3, TLR-7 and TLR-8 as well as the Th1 and Th2 cytokines in the serum of naturally Peste des petits ruminants virus (PPRV) infected goats. Goat serum samples, collected from three districts of Asom (Kamrup, Nalbari, Darrang), were screened for Peste des petits ruminants virus (PPRV) antibody by Complementary-ELISA. Out of 227 samples screened, 72 samples showed presence of PPR viral antibody with a percentage prevalence of 31.72%. Out of the positive samples, 39 were selected randomly for testing the TLR and cytokine response after PPRV infection. The study indicated TLR-8 to have an enhanced expression in serum of PPRV infected goats alongwith IL-12 and IFN-Î³ of the Th1 pathway. Further, in infected group, a significant correlation was registered between IL-12 and IFN-Î³. The present study showed the involvement of the Th-1 pathway in host immune response after PPRV natural infection which may help in proper disease management and control strategies.
