Abstract
Recently, the level of criminals and terrorists using light weapons (such as knives and firearms) has increased rapidly around the world. Unfortunately, most current surveillance systems are still based mainly on human monitoring and intervention. For that reason, the requirement for a smart system for detecting different weapons becomes crucial in the field of security and computer vision. In this article, a novel technique for detecting various types of weapons has been proposed. This system is based mainly on deep learning techniques, namely, You Only Look Once, version 8 (YOLOv8), to detect a different class of light weapons. Furthermore, this study focuses on detecting two armed human poses based on ensemble learning techniques, which involve combining the outputs of different Yolov8 models to produce an accurate and robust detection system. The proposed system is evaluated on the self-created weapons dataset comprising thousands of images of different classes of weapons. The experiment results of this work show the effectiveness of ensemble learning for detecting various weapons with high accuracy, achieving 97.2% of mean average precision.
Study on the current situation and influencing factors of corn import trade in China – based on the trade gravity model
Authors: He Hongxue 
Published: June 2024

Abstract
With the rapid development of China’s economy and society, the income level of Chinese residents is increasing day by day, and the dietary consumption structure of domestic residents is constantly optimized and upgraded. The consumption demand for livestock products such as meat, eggs and milk, and corn starch industrial products is increasing day by day. Therefore, as the main raw material of feed industry and deep processing owners, the consumption scale of China corn market is constantly expanding. However, the corresponding domestic corn production scale has not expanded, and the domestic corn production presents an obvious problem of insufficient supply scale, which leads to a sharp and rapid increase in the number of corn imports in China, which seriously impacts the domestic corn market and affects China’s healthy development of corn industry. In recent years, the continuous spread of the COVID-19 epidemic has seriously affected the global grain production and trade. The fierce military conflict between Russia and Ukraine, the two major grain exporting countries, has once again brought a serious adverse impact on the supply and price of the global grain market, resulting in an increase in the import cost of corn in China and a change in the import pattern of corn in China. In this regard, this study analyzes the current situation of corn production and import trade in China, and based on the relevant trade data between China and major corn importing countries from 2013 to 2022, establishes a trade gravity model to quantitatively evaluate the main factors affecting China’s corn import trade, and analyzes the trade potential of sample countries. It was found that in 2022, China’s import and export trade volume and trade value were 20.62 million tons and 7.11 billion US dollars, respectively, compared with 2013, trade volume and trade volume increased by 6.3 times. Statistics on the potential types of various trading countries showed that the proportion of potential countries was 14.2%, and Brazil had the greatest potential in China’s corn import trade. The proportion of potential expanding countries is about 71.4%, and Laos is a mature country with less opportunities for further development. In order to promote the benign development of the domestic corn industry and the development of China’s corn import trade, this paper puts forward a series of countermeasure suggestions based on the above research.
Zwischen Abhängigkeit und der Möglichkeit einer Kooperation: Beherbergungsbetriebe und ihre Strategien im Umgang mit Onlinebuchungsplattformen
Authors: Balk Anselm 
Published: June 2024

Zusammenfassung
Der Artikel behandelt mittels quantitativer Forschungsmethoden die Frage, wie Unternehmen in Branchen, in denen Onlineplattformen eine wesentliche Rolle im Wertschöpfungsprozess spielen, mit der sich daraus ergebenden Situation umgehen. Exemplarisch wird die Situation anhand von Beherbergungsbetrieben in Niederösterreich betrachtet. Dabei ist festzustellen, dass die Betriebe die Dienstleistungen der Onlinebuchungsplattformen (OTAs) mehrheitlich nutzen und wertschätzen. Allerdings sehen sie sich ihnen gegenüber in einem Abhängigkeitsverhältnis. Dies führt dazu, dass sie u.a. Provisionen akzeptieren, die als zu hoch wahrgenommen werden. Um dieses Abhängigkeitsverhältnis zu reduzieren, wird untersucht, ob und welche Lösungswege Betriebe sehen, um dies zu erreichen. Ein besonderer Fokus liegt hier auf gegenseitigen Kooperationsmöglichkeiten. Dabei ist festzustellen, dass die Mehrheit der Betriebe einer Zusammenarbeit positiv gegenübersteht. Maßnahmen, die darauf abzielen, Abhängigkeiten gegenüber OTAs zu reduzieren, indem ein Gegengewicht aufgebaut wird, werden jedoch skeptisch gesehen. Kommt es jedoch zu einer Kooperation, die zu einer indirekten Stärkung führt, sehen die Betriebe großes Potential. Hier können u.a. genossenschaftliche Ansätze beitragen. So untersucht der Artikel praxisgeleitete Möglichkeiten von Kooperationen und richtet sich neben einer akademischen Leserinnenschaft auch und insbesondere an Personen aus der Praxis.

Published: June 2024

Abstract
The textile industry contributes significantly to environmental pollution through the discharge of non-biodegradable colored dye effluents, emphasizing the need for effective wastewater treatment methods. Traditional approaches, including physical and biological treatments, face limitations, necessitating exploration into advanced oxidation processes (AOPs). Iron-based photocatalysts, particularly those synthesized through green methods, have shown promise in degrading organic pollutants. In this study, iron nanocomposites, including CSINCs, ASINCs, and ACINCs, are synthesized by mixing two different plant extract mixtures with an Iron precursor solution. XRD analysis confirms cubic structures for the prepared nanocomposites, with crystalline sizes of 14.21, 15.79, and 28.74 nm, respectively. UV–vis spectrophotometer shows characteristic absorption peaks in the 380–400 nm range. FESEM imaging reveals spherical particles, and EDX analysis detects typical signals of Fe, O, and C. FTIR spectra indicate various functional groups present in the nanocomposites. The study further focuses on optimizing the degradation of Reactive Blue 171 (RB 171) dye, considering factors such as pH, concentration of RB 171, and photocatalyst concentration. The results demonstrate that ACINCs, specifically at a concentration of 10 mg/100 mL in a mixture with Reactive Blue dye at a concentration of 50 ppm, exhibit enhanced degradation under UV irradiation. This detailed investigation contributes to the understanding of the structural and functional characteristics of Iron nanocomposites and their potential application in the efficient degradation of textile dyes, emphasizing the importance of optimizing key parameters for enhanced photocatalytic performance.

Published: June 2024

Critical care medicine department has to assess electrolytes accurately and quickly to initiate the treatment. Blood samples are analyzed in a matter of seconds by arterial blood gas analyzers (ABG), albeit their accuracy is still up for debate. The current study objectives were to estimate and compare the levels of electrolytes (sodium, potassium, and chloride) in hospitalized critical care patients as determined by automated biochemistry analysis and blood gas analyzer and to assess the degree of agreement between the two instruments and obtain information on whether these values can be interchanged. A prospective hospital based observational study was undertaken after obtaining institutional ethical committee clearance. The study included a total of 195 paired venous and arterial samples from the patients admitted to Critical Care Medicine Unit of NIMS Hospital, Jaipur, India in whom electrolytes were analysed on Arterial Blood Gas (ABG) analyzer and Automated Biochemistry Analyzer (ABA). Analysis was done on ABL555 blood gas analyzer located in the critical care medicine unit and vitros 5600, located in Clinical Biochemistry. Statistical analysis was done using Student’s t test and Pearson’s correlation coefficient test.A total of 195 samples were analyzed. The mean levels of sodium, potassium and chloride were 136.64 ± 5.44 mmol/L, 3.87 ± 0.523 mmol/L and 100.79 ± 6.65 mmol/L respectively analyzed by ABG analyzer. The mean levels of sodium, potassium and chloride were 136.65 ± 5.81mmol/L, 88 ± 0.543 mmol/L and 100.47 ± 6.41 mmol/L respectively analyzed by ABA. Student’s t test comparison p values for sodium, potassium and chloride were 0.458 (Not Significant), 0.1867 (Not Significant) and 0.0438 (Significant) between the two instruments. The strength of agreement between the two instruments for sodium, potassium and chloride were analyzed using pearsons correlation coefficient. There was strong agreement for all the three parameters between the two instruments and the p value was 0.00001 (highly significant) for all the three parameters.The results of this investigation showed no discernible differences between the automated biochemistry analyzer and arterial blood gas analyzer measurements of sodium, potassium, and chloride. Clinicians can make critically important decisions by relying on the results of arterial blood gas analysis.
