There are increasing opportunities for learners and instructors in different education level to engage in Internet-based or Internet assisted learning and instruction, therefore, it is important to explore pre-service and in-service preschool teachers' Internet attitudes and Internet self-efficacy. This paper explores 1210 Taiwanese preschool teachers, including 673 pre-service teachers and 537 in-service teachers' Internet attitudes and Internet self-efficacy. Internet Attitude Scale (IAS) and Internet Self-efficacy Scale (ISS) were conducted to assess preschool teachers' attitudes and their self-efficacy toward the Internet. Exploratory factor analyses indicated adequate reliability and validity of the two questionnaires. Results of this study were shown that in-service teachers' scores in perceived usefulness of Internet were significantly higher than the pre-service teachers' scores. However, pre-service teachers' scores in affection toward Internet were significantly higher than in-service teachers' scores. Moreover, the regression analyses revealed that preschool teachers' general self-efficacy can positively predict their Internet attitude of perceived usefulness, perceived control and behavior, and their communicative self-efficacy can positively predict their Internet attitude of perceived control and behavior. However, the preschool teachers' status (i.e. pre-service and in-service) was negatively predicting the Internet attitude of affection and behavior. As the results, the in-service preschool teachers would be more likely to be fill with anxiety when using the Internet and less frequently to use Internet.

Cybercrimes are multiplying and spreading at an elusive speed commensurate with the emerging technologies of the fourth revolution. Their sophistication and user’s vulnerability to attacks catalyze their success. Several surveys have been conducted to determine the factors favoring victimization. However, they can only be applied within a contextual framework since each ecosystem has particularities. Attempts in this direction are unavailable in Cameroon where cybercrimes cost 12.2 billion CFA in 2021. This work consists of a semi-direct survey conducted in Cameroon in 2021 to provide the determinants explaining the most frequent cybercriminal techniques, the vulnerabilities left by the users, the most targeted population segments, and the socio-demographic and economic factors justifying this security fragility. The results relate to 370 questionnaires collected throughout the territory. According to descriptive statistics and the chi-square test, the explanatory variables of cybercrime victimization are gender, age, intellectual level, level of digital knowledge, level of Information and Communication technology (ICT) proficiency, type of equipment used, the mobile and desktop operating system used, the possession of an anti-virus/anti-spam and the marital status. Within this work, we have identified threats and their drivers and a theoretical framework has been provided with several stages that could be followed to contain cybercrime. © 2023, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

Malignant tumors of the pancreas are the fourth leading cause of cancer-related deaths. This is mainly because they are often diagnosed at a late stage. One of the challenges in diagnosing focal lesions in the pancreas is the difficulty in distinguishing them from other conditions due to the unique location and anatomy of the organ, as well as the similarity in their ultrasound characteristics. One of the most sensitive imaging modalities of the pancreas is endoscopic ultrasonography. However, clinicians recognize that EUS is a difficult and highly operator-dependent method, while its results are highly dependent on the experience of the investigator. Hybrid technologies based on artificial intelligence methods can improve the accuracy and objectify the results of endosonographic diagnostics. Endoscopic ultrasonogra-phy was performed on 272 patients with focal lesions of the pancreatobiliary zone, who had been treated in the surgical section of the Kursk Regional Clinical Hospital in 2014–2023. The study utilized an Olympus EVIS EXERA II video information endoscopic system, along with an EU-ME1 ultrasound unit equipped with GF UM160 and GF UC140P-AL5 echo endoscopes. Out of the focal formations in the pancreatobiliary zone, pancreatic cancer was detected in 109 patients, accounting for 40.1% of the cases. Additionally, 40 patients (14.7%) were diagnosed with local forms of chronic pan-creatitis. The reference sonograms displayed distinguishable focal pancreatic pathologies, leading to the development of hybrid fuzzy mathematical decision-making rules at the South-West State University in Kursk, Russian Federation. This research resulted in the creation of a fuzzy hybrid model for the differential diagnosis of chronic focal pancreatitis and pancreatic cancer. Endoscopic ultrasonography, combined with hybrid fuzzy logic methodology, has made it possible to create a model for differentiating between chronic focal pancreatitis and pancreatic ductal adenocarcinoma.

The various parts of the palmyra and coconut trees which are widely distributed in the southern parts of the Indian subcontinent have been studied and utilized for many years. These contain a white and spongy edible component in them which is found during the germination of the seeds called haustorium. The palmyra and coconut trees each have different sections with special medical properties. Recently, the haustorium of both coconut and palmyra trees has been gaining increased attention from researchers due to its nutritional properties. Certain studies on the haustoria have revealed the presence of various compounds that are beneficial for human health. The bioactive compounds found in the previous studies include phenols, flavonoids, terpenoids, pyrimidine groups and certain vitamins which act as antioxidant, anti-inflammatory, anti-ulcer, anti-diabetic, anti-cancer, and anti-mutagenic agents. This review focuses on comparing the nutritional composition, bioactive compounds, sugar profile fatty acid profile, amino acid profile, minerals, and vitamins of both palmyra and coconut haustorium. This review also reports on the value addition of the haustoria as usually they are consumed in their raw form. These value-added products not only enhance the economic viability of these underutilized resources but also contribute to extending their shelf life, making them more accessible in the market. Also, this review emphasizes the haustorium's potential defence against negative consequences. Therefore, this review paper helps in understanding the palmyra and coconut haustorium and its potential health benefits. © 2024 The Author(s)

The purpose of this naturalistic study was to investigate the effect of booster seat design on the choice of children's seating positions during naturalistic riding. Data was collected through observations of children during in-vehicle riding by means of a film camera. The children were positioned in high back boosters in the rear seat while a parent drove the car. The study included two different booster designs: one with large head and torso side supports, and one with small head side supports and no torso side supports. Six children between three and six years of age participated in the study. Each child was observed in both boosters. The duration of the seating positions that each child assumed was quantified. The design with large side head supports resulted more often in seating positions without head and shoulder contact with the booster's back. There was shoulder-to-booster back contact during an average of 45% of riding time in the seat with the large head side supports compared to 75% in the seat with the small head supports. The children in the study were seated with the head in front of the front edge of the head side supports more than half the time, in both boosters. Laterally, the children were almost constantly positioned between the side supports of the booster in both seats. The observed seating positions probably reduce the desired protective effect by the side supports in side impact, and may increase the probability of head impact with the vehicle interior in frontal impact.

Since the late twentieth century, with the development of the Internet of Things (IoT), the IoT covers the application of comprehensive knowledge and technology in the fields of circuitry, physics, mechanics, and information, making it a suitable topic for hands-on science, technology, engineering, and mathematics (STEM) activities. The IoT covers a large amount of knowledge, practical skills, and programming skills in STEM fields, both teaching and learning the content can be difficult. Thus, this study used gamification with the 6E model and the software development method as the teaching strategies to explore their effects on high school students’ computer programming self-efficacy, IoT knowledge, and hands-on performance in IoT learning activities. In this study, a quasi-experimental design was used for 12 weeks, and the 132 students who participated in the experiment were divided into Experimental Group 1 (EG1, 66 students using gamification with the 6E model), Experimental Group 2 (EG2, 31 students using the 6E model only), and the Control Group (CG, 35 students using the software development method). Through Analysis of Covariance, the results showed that the students in EG 1 achieved higher academic performance in terms of computer programming self-efficacy, IoT knowledge, and hands-on skills. The results of the lag sequence analysis of behavioral patterns showed that all the students required frequent two-way communication with the teachers and needed to communicate with their group members. The students in EG 1 exhibited positive interactions and took the initiative in asking for help from other students, which indicated that the students in this group achieved better learning outcomes. In addition, those interested in exploring STEM hands-on activities would benefit from our findings.

Employability denotes skills and attributes that make an individual desirable to potential employers. Owing to the dramatic increase in enrollment rate of higher education, a diploma is no longer a guarantee of employment and higher education institutes are expected to equip students with employability skills and attributes. However, the mandatory inclusion of employability skills and attributes in higher education has provoked considerable debate and controversy. Although the connection between employability and employment is well-documented, it is not clear whether employability skills have potential impacts on academic performance of graduate students. This study investigated the relationship between academic publication and perceived employability of graduate students in business and management by analyzing data from Graduate Destination Survey (GDS) in Taiwan. Of the 6,876 graduate students in business and management responding to the survey, 2,015 (29.3%) and 508 (7.4%) of them submitted at least one conference paper or peer-reviewed journal article, respectively. Logistic regression was used to evaluate the associations between paper/article submission and perceived employability of graduate students, controlled for student attributes. The findings suggest that 4 employability skills are significantly associated with academic publication of graduate students, including “foreign language ability”, “computer literacy”, “application of theory to work”, and “stability and pressure resistance”. All control factors, including “school type”, “gender”, “entrance exam for graduate school”, “years in graduate school”, “full-time student”, and “participation in academic community”, have significantly connection with academic publication. The results imply that employability is not only associated with employment processes but also related to academic publication of graduate students and provide insights into the potential benefits of enhancing employability to both stud

A new group of tributyloctylphosphonium-based ionic liquids containing several carboxylate anions was designed, prepared and physicochemically characterized. All phosphonium carboxylates obtained in this study became viscous liquids at room temperature. The formate-based ionic liquid exhibited the highest density and number density due to the smallest anion size. All ionic liquids exhibited typical ionic conduction behavior, since the viscosity decreased and the conductivity increased with increasing temperature. It was also found that the viscosity tended to decrease with increasing the carbon numbers of the alkyl chains of lower carboxylate anions. Compared to the propionate-based ionic liquids, lactate-based ionic liquids exhibited higher viscosity. The phosphonium ionic liquids based on carboxylate anions showed higher thermal stability than nitrogen-based counterpart ionic liquids. ©The Electrochemical Society.

The South African platinum mining industry faces continuous challenges in terms of increased global competition, demand for productivity, skills shortages, loss of scarce technical skills due to emigration, strikes and high turnover rates. Hence, the lack of engineering skills (technical and management skills) may seriously hamper the capacity of the mining industry to ensure that productivity and safety standards are maintained. A quantitative study was conducted on skills needed by platinum mining engineers in three provinces in South Africa. A four-point Likert-type scale questionnaire ranging from strongly agree to strongly disagree was developed. The Cronbach's alpha coefficient was above 0.8, indicating high internal reliability. The population consisted of 300 engineers in platinum mines in three provinces in South Africa. A convenience sample was used; 79 engineers volunteered to complete the questionnaire. The response rate was 26.3%. A factor analysis was conducted to determine which skills of the engineers were the main concerns. The results of the study indicated that theoretical knowledge, technical skills, management skills and engineering principles were skills needed for technology-based engineering in the platinum mines under study.
