With the increasing significance of travel retail within the global tourism industry, understanding the effects of duty-free shopping experiences on traveler well-being and brand perceptions has become crucial for enhancing customer satisfaction and engagement. This study examines the relationships between duty-free shopping experiences, traveler well-being, and brand perceptions at King Fahd International Airport. Utilizing a quantitative research approach, data were collected from 412 passengers who had recently engaged with duty-free shops. The study incorporated four key experiential dimensions—pragmatic, sociability, hedonic, and usability experiences—alongside well-being, brand engagement, brand experience, and word-of-mouth (WOM) advocacy. The findings indicated positive associations between well-being and pragmatic, hedonic, and usability experiences. Moreover, well-being significantly influenced brand engagement and brand experience, but not WOM. Brand engagement was found to be a significant predictor of brand experience, while it had no significant effect on WOM. Additionally, WOM did not significantly influence brand experience. These insights contribute to a comprehensive understanding of the intricate interplay between shopping experiences, well-being, and brand-related outcomes, providing valuable guidance for airport retailers and marketers to optimize traveler satisfaction and engagement.

Authors: Zhao Hashengaowa
Published: February 2024

The traditional Japanese language teaching method is challenging to mobilize students’ enthusiasm, and it is impossible to objectively understand students’ mastery of knowledge points. To address this teaching problem, this paper combines the CRS model with K-Means cluster analysis to construct a precise teaching model for teaching Japanese language in colleges and universities based on the CRS model. Through the CRS model to obtain the students’ mastery of knowledge and differentiated data, the K-Means algorithm is used to analyze the teaching model accurately, so Japanese teachers can make timely adjustments to the classroom teaching situation and improve the quality of teaching. After the model design was completed, a controlled teaching experiment was conducted in two colleges and universities in a province, and an independent square root t-test was performed. The ratio of teachers’ verbal behavior in the experimental class of Japanese language in colleges and universities was 71.58%, which was 18.86% lower than the ratio of teachers’ verbal behavior in the classroom of the control case, and the ratio of students’ verbal behavior was 21.58%, which was 18.36% higher. The average probability of students’ mastery of the Japanese language points studied in the semester was above 0.6. The independent square root t-test for the two classes was less than 0.05, showing a significant difference.

Authors: Xie Ting
Published: February 2024

Driven by deep learning techniques in recent years, single target recognition and tracking techniques have developed significantly, but face challenges of real-time and accuracy. In this study, an improved IPSO-BP network is formed by optimizing three critical aspects of the IPSO algorithm: adjusting the inertia weight calculation formula, improving the learning factor, and creating a new iterative formula for particle updating, which in turn is combined with a BP neural network. After iterative training, this paper constructs a single target recognition tracking algorithm with higher efficiency. The Algorithm’s performance is comprehensively tested through experimental simulation in terms of real-time, accuracy and stability. The results show that the improved Algorithm can achieve a frame rate (FPS) of up to 31 in single target recognition and tracking. The IOU value is as high as about 83% in some tests. The tracking success rate in different scenarios averages approximately 98.50%, the position error is controlled within 0.7 m, and the speed error averages 2.75 m/s. This improved IPSO-BP neural network effectively solves the problems of the current technology in the areas of real-time and accuracy, showing high stability and accuracy.

Published: February 2024

This paper provides an in-depth study on the application of digital sensor technology in electrical fire detection. It firstly focuses on the design of electrical parameters to improve the accuracy of fire detection. Based on the research results of recurrent neural networks, the article combines the Long Short-Term Memory (LSTM) network and the Gated Recurrent Unit (GRU) neural network. It innovatively proposes an electrical fire feature recognition method based on the LSTMGRU network. The study also incorporates fuzzy inference techniques to optimize the fire alarm decision-making process, which achieves a hierarchical output for electrical fire detection recognition and alarm decision-making. The experimental results show that the LSTM-GRU network achieves an accuracy of 98.83% in electrical fire classification and recognition, significantly better than the results of using LSTM network or GRU network alone. Regarding electrical fire distance recognition, the relative error of the method only ranges from 0.32% to 2.10%, and its output of fire alarm decision is entirely correct. The study not only verifies the high accuracy and reasonableness of the electrical fire feature recognition method based on digital sensing technology, but also provides a brand new idea for recognizing electrical fire detection and alarm decision-making.

Authors: Liu Quansheng , Ma Shiming
Published: February 2024

In this paper, we propose a new DDoS attack detection mechanism based on federated learning that employs dynamic thresholds to cope with the fluctuation of variable rate DDoS attacks. The performance of this detection mechanism is analyzed in terms of traffic classification, performance of verification module, accuracy and loss value. Experimental results show that the method has an accuracy of 99.83% in detecting regular Benign traffic. In burst attack scenarios, the technique significantly improves detection accuracy for all 10 common DDoS attack types. In a sustained attack environment, the intrusion detection system trained based on the DDoS model has the most minor performance degradation, and the average detection accuracy for all types of DDoS attacks still exceeds 90%. Compared with the traditional SVM model, the DDoS attack detection model based on federated learning has a significant performance advantage with Loss and Acc parameters of 0.1 and 0.9, respectively.

Effect of Dietary Protein to Energy Ratios on Growth, Digestive Enzyme Activity and Body Composition of Captive Juvenile Spiny Lobsters, Panulirus Ornatus (Fabricius, 1798)
Authors: Saputra Ishaaq , Fotedar Ravi
Published: February 2024

An evaluation of six dietary protein-to-energy (P/E) ratios was conducted to the early juvenile lobsters (Panulirus ornatus) by investigating the ratio effects on physiology, digestive enzyme activities, body composition, and amino acid profiles. Juvenile lobsters (0.25±0.01 g) were individually kept in aquaria and treated with six isoenergetic formulated diets of P/E ratios of 21.8, 22.5, 23.5, 24.6, 25.3 and 26.6 mg KJ–1. After 8 weeks of feeding experiment, the differentiation on dietary P/E ratios was found to have affected the specific growth rates, but not the survival, moult increment, moulting rate, moult interval and average daily moulting rate of juvenile lobsters. The dietary P/E ratio also influenced the protease, lipase, superoxidase dismutase activities, and body composition of juvenile lobster. The increase in dietary protein levels significantly affected the increase of the specific growth rate, while increased dietary lipid levels only affected the length increments. Both protein and lipid content were found in the whole body of the juveniles which reflected the treated dietary composition. Results indicated that a P/E ratio of 26.6 mg KJ–1 (55% dietary protein and 9% dietary lipids) can yield the maximum growth and digestive enzyme activities from among the studied diets.

Published: February 2024

The variation in egg quality parameters of traditional/native hen breeds with good freshness and antibacterial properties of egg albumen may determine the attractiveness of these eggs for modern consumers looking for high quality products. The objective of this study was to evaluate external and internal physical quality parameters and enzymatic activity of lysozyme of eggs from three traditional hens bred in Poland and to compare these egg quality parameters to those obtained from commercial hybrids kept under the same management conditions in extensive farming production system. The study was carried out on eggs collected from 4 genetic groups of hens, i.e. Polish Liliputy Bantams (PLB), native Polish Crested Chickens (PCr, CP-22 strain), Gold Laced Polish Chickens (GLP) and from Hy–Line Brown hybrids (HLB). In total 135 PLB, 75 PCr, 75 GLP and 75 HLB hens were kept on litter (3 pens) and fed commercial feed. The eggs (n = 33/genotype/age) were collected at the 33 and 55 weeks of age. The study concluded that with the age of the hens, there was an increase (P<0.05) in the weight of the egg and the proportion of its main fractions, as well as a decrease (P<0.05) in the quality parameters of the albumen and the eggshell. However the eggs from traditional breeds retain good parameters of albumen quality even at the end of production period. The eggs of traditional hens were characterized by higher (P<0.05) yolk proportion and its color and albumen lysozyme parameters, and a lower (P<0.05) eggshell and albumen height and Haugh unit score in relation to commercial hybrids. The highest (P<0.05) content of lysozyme and enzymatic activity of lysozyme were found in eggs from Gold Laced Polish Chickens. Thus, eggs obtained from traditional hens may meet requirements of modern consumers because of specific physical characteristics, good albumen lysozyme activity and freshness parameters. Particularly noteworthy are Polish Liliputy Bantams eggs, characterized by the low weight and a high proportion of more intensely colored yolk and good Haugh unit score at the end of production period.

The growing number of road accidents and fatalities created a necessity for applications exploiting communication between traffic actors like vehicles, vulnerable road users (VRUs), and infrastructure. To determine the vehicle position and to communicate this data to the traffic users, the vehicles and user’s smart devices are equipped with communication modules and positioning modules. The fifth generation (5G) cellular network promises to respond to the requirements of a city traffic management by: ultra-low latency, reliability, and position determined with high precision. The 3GPP Release 16 mobile communications standard details the use-cases of the industrial verticals and their requirements, the most important key performance indicators (KPIs), and technologies that the new radio (NR) architectural component uses to obtain the position information. 3GPP Release 16 targets a positioning accuracy between 1 and 3 meters for traffic monitoring and control, as well as for wearable devices. Moreover, the standard specifies the most common solutions that the 5G technology can support. This paper aims at presenting the context of the positioning essentials that the 5G NR can support, which are necessary to achieve road users’ protection and congestion avoidance within an urban area.

Published: February 2024

The switching of electrical equipment in normal operation conditions should be performed in optimal moments with regard to the variation of the voltage and current waveforms. Deviations from these ideal conditions will result in disruptive transient regimes, which, depending on their severity, can lead to equipment malfunctions or insulation damage. This paper continues a previous research study regarding the impact of the real switching moment regarding the known ideal conditions on various types of equipment. Previous efforts have concentrated on the study of the behavior of capacitor banks, power transformers and underground cable lines when switching is performed in different points on the voltage sine wave. This paper continues the research by studying high voltage overhead lines in the same conditions. The voltage and current waveforms are measured and analyzed for different switching times, using the EMTP software package. A comparison discussion with the previous results highlights the main findings.

Authors: Sampaio Nilo Antônio S. , Mazza Felipe Cury , De Siqueira Sílvio Sérgio Silveira , Miranda Junior João Ercio , De Abreu Laura Dutra , De Lima Rafael Martins
Published: February 2024

Objective: The aim of this paper is to show the application of the Non-Parametric Sign Test in problems involving the testing of central tendency values.
 
Theoretical framework: Non-parametric methods are widely used in the study of populations that are taken in rank order (such as a movie that receives one to four star ratings). The use of non-parametric methods may also be necessary when the data has a ranking but no clear numerical interpretation, such as when accessing preferences. In terms of scale, non-parametric methods result in data that is "in order" (Thatcher et al., 2005)
 
Method: Data was taken from a company in the South of Rio de Janeiro and a case study was carried out using the Non-Parametric Sign Test.
 
Final Considerations: Initially it proved unfeasible to use a Parametric Test because the Anderson-Darling Test showed that the Assumption of Normality was not confirmed and finally the Non-Parametric Sign Test showed that the hypothetical Median really is the correct measure of Central Tendency.
 
Implications of the research: The use of Non-Parametric Tests is widespread in scientific literature and has proven to be highly effective in dealing with data where the assumptions of Normality are not confirmed.
 
Originality/value: Despite being well-known statistical tools, Non-Parametric Tests are widely used and can bring innovations to their application, as in the case of the company in question.
Methods of regional analgesia in abdominal surgery in pediatrics
Authors: Barminskiy A. V. , Egorov A. N. , Kirov M. Yu.
Published: February 2024

Introduction. Adequacy of perioperative analgesia is one of the main issues of surgical care. Anatomo-physiological and psychological characteristics of childhood necessitate more thorough approach to this problem in pediatric anesthesiology, since ensuring optimal analgesia provides prevention of somatic perioperative complications and influences further physiological neuropsychiatric development of a child.

The objective was to compare regional techniques of perioperative analgesia during abdominal interventions in children and to discuss the conditionsof their application and effectiveness.

Materials and Methods. A literature search was conducted using PubMed, Medline, Embase, and Google Scholar databases. Both English – and Russian-language publications indexed in Scopus and RSCI were included in the search.

Results. Among methods of regional anesthesia, neuroaxial blockade options, which have both high proven efficacy and several disadvantages and complications, remain the most popular techniques. Currently, the alternative methods are available, presented as interfascial blockades with anefficacy comparable to neuroaxial techniques and a wide safety profile. Among these techniques, we can distinguish rectus sheath block, transversus abdominis plane block, erector spinae plane block and other methods.

Conclusion. Despite advances in pain management, inadequate postoperative analgesia in pediatric practice remains a serious problem. Therefore, it is important to optimize the treatment of postoperative pain in children by applying multimodal analgesia using modern regional blockades.
Aspects of intensive therapy of diabetic ketoacidosis in pediatric practice (literature review)
Authors: Bykov Yu. V. , Muravyeva А. А.
Published: February 2024

Diabetic ketoacidosis (DKA) is an acute and severe complication of type 1 diabetes mellitus that is associated with a high risk of cerebral edema (CE)and may result in death. DKA is characterized by acute hyperglycemia, ketonemia and metabolic acidosis in the setting of decreased levels of insulin and excessive levels of the counter regulatory hormones. Algorithms of intensive treatment of DKA include such steps as fluid replacement therapy, correction of electrolyte imbalances, and intravenous infusion of insulin, performed in order to resolve metabolic acidosis and hyperglycemia as well as to prevent the development of complications (CE and hypokalemia). The analysis of literature has shown that during fluid replacement the most preferred options are balanced crystalloid solutions (Hartman’s solution and Plasma-Lyte). Infusion therapy is divided into bolus (administration of crystalloid solutions at the rate of 10 ml / kg for 30-60 minutes) and maintenance (administration of solutions for 24-48 hours). Intravenous glucosesolutions (5–10 %) are infused when the patient’s blood glucose falls below 14–16 mmol/L. Electrolyte disturbances (hypokalemia and hyponatremia) are resolved by prompt intravenous infusion of potassium and sodium solutions. Intravenous infusion of insulin is started at the rate of 0.05–0.1 U/kg/h, not earlier than 1 hour after the initiation of fluid resuscitation. Successful treatment of DKA in pediatric practice relies on clear understanding of the pathophysiological mechanisms of this complication and knowledge of the doses of the pharmaceutical drugs and volumes of infusion solutions to be used.
Hematological, biochemical, coagulation profiles of patients with cerebral palsy and epilepsy on the background of taking valproic acid in the perioperative period
Authors: Evreinov V. V.
Published: February 2024

Introduction. Valproic acid is one of the commonly prescribed basic anticonvulsants for the treatment of epileptic seizures in children with cerebral palsy. Its active metabolites can cause hematological and coagulation disorders, cause valproate-induced steatohepatitis.The objective was to assess the level of hematological, biochemical and coagulation blood parameters in the perioperative period in children with severe forms of cerebral palsy during the treatment of concomitant epilepsy with valproic acid.

Materials and methods.  A prospective cohort study included 72 patients with cerebral palsy, spastic hip dislocations, who underwent reconstructive interventions on hip joints. Depending on the presence of concomitant epilepsy, the patients were divided into two groups. Perioperative laboratory blood parameters, complication incidence, the duration of stay in the intensive care unit and hospitalization were assessed.

Results.  In patients with epilepsy, the number of platelets in the blood was lower compared to the control group. The level of alkaline phosphatase before and after surgery in 34 % of children who took anticonvulsants exceeded the maximum value of the norm. Groups differed in terms of peri -operative coagulogram and thromboelastography. The frequency of complications in patients with epilepsy ranged from 0.08 % to 16.2 %.

Conclusions.  Basic therapy with valproic acid in children with severe forms of cerebral palsy and concomitant epilepsy is associated with a tendency to hypocoagulation, but was not accompanied by clinically significant thrombocytopenia or coagulopathy during hip surgery. Taking valproic acid drugs in patients with cerebral palsy and epilepsy was not accompanied by an increase in serum liver enzymes at all stages of  observation, which minimized the likelihood of valproate-induced hepatotoxicity. Anticonvulsant therapy with valproate in children with severe forms of cerebral palsy and concomitant epilepsy did not increase the potential risk of complications in the perioperative period, did not affect the duration of stay of patients in the intensive care unit and hospitalization.

Published: February 2024

The objective was to study the risk factors, outcomes of infections caused by colistin-resistant K. pneumonia (CRKP) and to evaluate the  sensitivity of these microorganisms to antibacterial agents to determine the most adequate antibiotic therapy options.

Materials and methods. Klebsiella pneumoniae strains isolated in the ICU of an acute care hospital between October 2020 and August 2022 were included in the study. Microorganisms were identified using an automatic analyzer PHOENIX. The determination of antibiotic sensitivity was studied by the method of serial micro-dilutions in agar with the determination of MIC EUCAST criteria were used to interpret sensitivity. Detection of carbapenemases was carried out by PCR. Clinical efficacy of starter therapy was evaluated as recovery/improvement and no effect.

Results. The infection was characterized by a severe course in 58.9 % of patients, with SOFA scores ranging from 1 to 16 points (mean 5.8 points). 88.2  % of patients had received prior antibiotics, most commonly carbapenems. CRKP infections occurred more frequently in older men with comorbidity. The clinical efficacy of initial antibiotic therapy was 41.2 %. In 47.1 % of cases, there was no effect, which required adjustment of therapy. Excluding patients in whom it was impossible to evaluate the effect, eradication was achieved in 33.3 % of patients. 64.6 % of patients were discharged or transferred to another hospital; 6 patients died between 5 and 41 days after diagnosis of CRKP infection. Fatal outcome was more frequent in women ( p=0.042), patients with higher comorbidity index (p=0.027), in case of sepsis and/or septic shock ( p=0.011), and in earlier detection of CRKP after hospitalization ( p<0.001).

Conclusion. The efficacy of initial antibiotic therapy after detection of CRKP infection has been shown to be associated with patient  survival and reduced risk of mortality with an odds ratio of 3.5. We also identified risk factors for mortality in CRKP infection: comorbidity, sepsis, duration of hospitalization and female gender.

Introduction . The choice of the method and time of initiation of extracorporeal detoxification (ECD) in septic shock (SSh) complicated by acute kidney injury (AKI) is a debatable problem.

The objective was to evaluate the influence of various ECD tactics on the dynamics of markers of systemic endotoxicosis and acid-base status (ABS) in patients with SSh complicated by AKI.

Materials and methods. Study included 57 patients. Group 1 – 36 patients used continuous veno-venous hemodiafiltration (CVVHDF) for urgent indications. Group 2 – 21 patients used early combined ECD (LPS-sorption and CVVHDF). A comparative analysis of the main laboratory parameters between the groups was performed.

Results. Early combined ECD made it possible to reduce the concentration of leukocytes by the 3rd day of therapy from 20.6 to 12.5 ·109/l (39.3 %) from the initial level in group 2, and from 22.2 to 19.15·109/l (13.7 %) in group 1 ( p=0.04); C-reactive protein by the 5th day of therapy from 284 to 145 mg/l (48.9 %) in group 2, and from 299.3 to 199.8 mg/l (33.2 %) in group 1 ( p=0.02); procalcitonin by the 5th day of therapy from 7.2 to 1.6 ng/ml (77.8 %) in group 2, and from 7.8 to 4.45 ng/ml (42.9 %) in group 1 ( p= 0.02); pH by the 3rd day of therapy from 7.17 to 7.37 in group 2, and from 7.19 to 7.27 in group 1 (p =0.04); IL-6 level by the 5th day of therapy from 764.9 to 361.7 pg/ml (52.7 %) in group 2, and from 700.1 to 542.5 pg/ml (22.5 %) in group 1 (p=0.007).

Conclusions. Early combined ECD more quickly reduces markers of systemic endotoxicosis and eliminates impairment of ABS, than CVVHDF.

The objective was to evaluate the effect of renal replacement therapy on the concentration of tigecycline in the blood in the treatment of patients with sepsis and acute kidney injury.

Materials and methods. The serum level of tigecycline was analyzed in three patients with sepsis-associated acute kidney injury against the back -ground of renal replacement therapy (RRT) in the hemodiafiltration mode. The quantitative content of tigecycline was determined by high-performance liquid chromatography.

Results. Significant variability of serum tigecycline levels was revealed in patients with sepsis-associated acute kidney injury (AKI) under the conditions of the use of RRT. The use of standard dosage regimens of tigecycline in this situation may be accompanied by both a significant increase in the concentration of the drug in the blood relative to the target values, and its low level, which does not reach the values of the minimum inhibitory concentration (MIC) for pathogenic strains.

Conclusion. Significant variability of serum concentrations of tigecycline in patients with sepsis-associated AKI against the background of RRT causes the emergence of potential risks associated with both insufficient safety of treatment due to possible accumulation and  significant excess of the target concentration value against the background of inhibition of the functions of the physiological excretory systems  of the body, so with the low effectiveness of antibacterial therapy in conditions of increasing the rate of elimination of the drug from the  systemic bloodstream due to extracorporeal clearance and reducing the concentration of the antibiotic to subtherapeutic.

The objective was to study the occurrence of perioperative cardiovascular complications (CVС) and clinical and laboratory cardioprotection parameters in patients treated with an infusion of a succinate-containing drug during the intraoperative period of vascular surgery.

Materials and methods. The study involved 120 patients with high cardiac risk (revised cardiac risk index  > 2, risk of perioperative myocardial infarction or cardiac arrest  > 1 %) who underwent elective vascular surgery. Patients were randomly divided into two groups. Patients of group 1 received intraoperative infusion of succinate-containing drug at a dose of succinate 0.35 [0.26–0.40] mg/kg/min– 1. Group II was a control group. In the perioperative period, the occurrence of perioperative CVC, the blood level of the N-terminal segment of natriuretic B-type prohormone (NT-proBNP) and cardiospecific troponin I (cTnI) were analyzed.

Results.  Perioperative CVC was registered in 11 (18.3 %) patients of group I and in 11 (18.3 %) patients of group II (p   =  1.0). The level of NT-proBNP in patients of group I and group II was 207  [160–300] pg/ml and 229  [150.6–298.9] pg/ml (p   =   0.817) before surgery, 234.2 [155.9–356] and 277 [177.7–404] pg/ml ( p   =  0.207) after surgery and 240.5[149.3–306] and 235.5 [133–495.1] pg/ml ( p   =  0.979) before discharge from the hospital. An increased level of cTnI after surgery was recorded in 4 (6.7 %) patients of group I and in 1 (1.7 %) patient ( p   =  0.364) of group II.

Conclusion. Intraoperative infusion of succinate-containing drug does not affect the occurrence of CVC in patients with high cardiac risk during vascular surgery. The succinate-containing drug does not affect the preoperative level of NT-proBNP and cTnI.
Investigation and Modeling of Biogas Production Potential from Urban and Fruit Juice Wastewater Treatment Plant Sludge through Pretreatment
Authors: Bayrak Işık Esin Hande
Published: February 2024

In this study, the effect of pretreatments applied to the sewage sludge of the Tokat Municipality wastewater treatment plant (WTP), the sewage sludge of the packaged wastewater treatment plant (PWTP) of a fruit juice production plant, and the aqueous phases of their mixtures on biogas production was investigated. Chemical, thermal (microwave (MW) and hot plate (HP)) and chemical-thermal pretreatments were applied to these sludge samples. Considering the results in all samples, the highest biogas production amount and efficiency were found in the pre-biogas-unit aqueous phase of the sewage sludge of the Tokat WTP, which was applied 20% H2SO4+10-minute (min) thermal MW pretreatment, with 667.51 ml and 396.34 ml biogas/g water dissolved SM value, respectively. Statistical analyses included the Duncan comparison test for cumulative biogas production efficiencies at the end of 65 days and the maximum exponential increase function and Gompertz equations for cumulative biogas amounts. Accordingly, the most appropriate model was tried to be determined. The electricity generated at the end of the 22-day incubation period at the facility meets 36% of the electricity needed by the Tokat WTP. At the end of the experimental studies (20% H2SO4+10 min thermal MW pretreatment), it can be said according to the 22-day biogas data that the biogas production efficiency increased by 3.41 times, this would meet all the electricity needed by the facility, and that there would be an extra 23% electricity generation of the total generation. Mixing and using fruit juice PWTP and WTP treatment sludge in the production of biogas will enable both the utilization of this waste in biogas production and the weakening and reduction of high parameter values, which sometimes cause problems in the sludge discharged from the Tokat WTP due to urban wastewater treatment, to acceptable limits.
Effect of Rosemary (Rosmarinus officinalis L.) Powder Supplementation on Silage Fermentation Characteristics, Silage Quality, and In Vitro Digestibility in Corn Silage
Authors: Doğan Daş Besime
Published: February 2024

The purpose of this study was to investigate how the addition of rosemary to corn silage affected the quality, fermentation, and in vitro digestion of organic matter. In the study, unaltered silage group constituted the control group, while silages prepared by adding 0.5, 1 and 2% rosemary constituted the experimental groups. After 60 days of ensiling, the pH of the opened silages was determined to be in the range of 3.67-3.72. As the amount of rosemary in the silages increased, the levels of ammonia nitrogen (NH3-N/TN) decreased. Compared to the control group, increases in in-vitro organic matter digestion (IVOMD) and metabolizable energy (ME) values were observed in the experimental groups due to the addition of rosemary. In comparison to the control group, the methane gas (CH4) rate of silages was reduced in the other groups. Meanwhile, the group receiving 2% addition of rosemary had the highest values of acetic acid (AA) and lactic acid (LA) among the supplemented silage groups. But, propionic acid (PA) and butyric acid (BA) were not detected in any of the silage groups. Consequently, it was determined that 1% and 2% of rosemary added to corn silage can enhance the quality of the silage.

Authors: Kaya Aybüke
Published: February 2024

The aim of study is to reveal the factors affecting the knowledge sources used by melon farmers in Hatay province, and their attitudes towards input use. In addition, the research also investigated farmers’ attitudes towards plant protection knowledge and support policies. In the study was surveyed with melon farmers. The data were obtained through face to face interviews during the period of Summer-2022. In the study, factor analysis was used to determine farmers’ the factors affecting the knowledge sources. Factors affecting the knowledge sources used by farmers were determined as two-way and one-way communication. The factors affecting the sources that farmers depend on in dose adjustment were determined as internal and external factors. Besides, farmers think that the knowledge sources should be understandable and accessible. On the other hand, farmers think that the sources they depend on should be accurate and reliable. In melon cultivation, chemicals are used excessively to combat diseases and pests. Also, farmers stated that if precautions are not taken while spraying, poisoning may occur. Moreover, it is thought that empty pesticide containers should be destroyed and excessive use of fertilizers and pesticides may harm products and the environment. Furthermore, farmers claimed that support policies for melon production were not sufficient. As a result, it has been understood that melon farmers have a good level of education and are conscious individuals. However, it is thought that the training and extension activities will help farmers increase their income and environmental awareness.

This study aimed to investigate the volatile organic compounds (VOCs) variations during the spoilage of palm wine stored at ambient temperature and identify potential shelf-life markers. Palm wine collected from local tappers and resellers were stored at ambient temperature (28-30°C) for 96 h. At an interval of 24 h, VOCs variations were investigated using Solid phase Microextraction-Gas Chromatography-Mass Spectroscopy (SPME-GC/MS) method. Changes in sensory quality and potential flavour contributors were also explored. The sensory rejection time was found at 24 h and 48 h of storage for palm wines collected from the tappers and resellers, respectively. The first attribute to be spoiled was taste followed by odour and appearance. A total of 23 VOCs distributed in six chemical families were identified. Alteration of palm wine sample is characterised by an increase in concentration of alcohol (isoamyl alcohol, isobutanol and 1-octanol), aceti acid and acetoin, and a decrease in ester concentration (ethyl acetate and ethyl hexanoate). In the view to fight against the short shelf-life and develop new preservation methods, these compounds can be used as markers of spoiled palm wine.

Pickles, which are known to have many nutritional and health benefits, have been used as a nutritional supplement in many cultures in recent years. Lactic acid bacteria, in its natural microbiota of pickle, which have various probiotic properties such as increased natural resistance to infectious diseases in the gastrointestinal system, prevention of various infections, and reduction in cholesterol level are effective in this. In our study, various combinations of salt, vinegar and lemon acid were made to produce gabbage pickled and it was determined how it affected the natural microbiota during fermentation. When the results were evaluated in terms of the viability of lactic acid bacteria, the best results were obtained with 5.35 logarithms in the G2 produced using only 5% lemon juice from eight different groups, one of which was a control. In the G3 which was produced using 5% vinegar, this number was determined as 1.82 logarithms. At the end of fermentation, it was determined that the coliform groups in the experimental groups lost their viability. Yeasts were completed this process with an average of 1 logarithm. When all test groups were examined in terms of all microbiological results was showed that the production of 5% lemon juice G2 has optimally results in terms of growing LAB and inhibition the undesirable microbial groups
