Published: April 2024

With the advent of the era of “Internet+ education,” the management mode of vocational education is facing enormous challenges, and the problems of traditional classroom management and student management are becoming more obvious. This paper analyzes the practical significance, opportunities, and challenges of the Internet in the management of vocational education, and finds that only by updating and improving the management model of vocational education can we cultivate socially applicable and practical high-tech skilled talents. Therefore, it is important to establish an information platform and practice refined management, adhering to the student-oriented concept of humanized education management. The management team can also be upgraded to improve management efficiency. We should pay attention to social practice and strengthen our internal management, develop electronic archives for tracking growth, and give full play to the potential of the network to implement democratic management. In this paper, the use of network tools to strengthen the communication between homes and schools, and the other six aspects of the “Internet+ vocational education management mode” are explored.

Authors: Wang Jie , Jiang Chengjun
Published: April 2024

The study of the relative clause (RC) attachment is important in revealing the internal psychological processes of processing ambiguous sentences. It is worth exploring whether the existing attachment hypotheses apply to second and third-language learners. This study used an offline sentence acceptance test method to conduct a relative clause attachment ambiguity bias experiment on 35 Chinese students whose second language is English and whose third language is Thai. Research has shown that the subjects do not exhibit a significant attachment bias when processing ambiguous sentences related to English and Thai relative clauses with the NP1 of NP2-RC structure, but exhibited significant proximity bias when processing ambiguous sentences with the NP1 of NP2-RC structure.
The Path of Transforming Excellent Retired Athletes into Physical Education Teachers
Authors: Ding Danyao
Published: April 2024

With the vigorous development of sports in our country, many excellent athletes have been trained over the years, achieving brilliant feats on the field. However, after retirement, they face new challenges—transformation and development. In the new era of the integration of sports and education, the “retired athletes re-employment problem” and “solving the problem of the shortage of primary and secondary school sports teachers” are organically linked. This linkage aims to realize the complementarity of social supply and demand, which the entire Chinese sports industry is actively exploring and addressing. The integration of retired athletes into the education system will not only help improve the quality of physical education and broaden employment channels but, more importantly, address the shortage of physical education teachers in schools. Sports teachers transitioning from athlete roles possess unique advantages. However, due to the shift in professional roles and distinct occupational requirements, they need a bridge and path for successful transformation.
Teacher Stress During Educational Processes with Physical and Remote Attendance Regarding the Covid-19 Pandemic – A Secondary Publication
Authors: Rosero Morán Cristina del Rocío
Published: April 2024

The integration of new technologies and the increase in workload have influenced teaching performance, thereby affecting the development of teaching-learning activities. The balance between time dedicated to professional practice and time available for physical and psychological rest is analyzed based on the definition of stress as a collection of daily situations that impact the personal and professional development of an individual, which escalated during the COVID-19 pandemic with the rise of virtual educational practices. The study, conducted in two educational units in Quito, Ecuador, involved administering the Maslach Burnout Inventory questionnaire to 155 participants, alongside collecting data on sociodemographic variables. Statistical analysis was performed using the JASP 0.15 program. The results indicate the level of work stress experienced by teachers, depending on various sociodemographic variables including rural or urban setting, gender, age, level of education, marital status, and cohabitation arrangements. A statistically significant correlation (< 0.001) was observed, particularly regarding the challenge faced by over half of the participants (0.51) in finding time for postgraduate studies. Additionally, a moderate correlation was found between inattention and various symptoms: frustration (0.46), guilt (0.36), weariness (0.26), tiredness (0.51), lack of attention (0.26), and the importance of work (0.43). These findings prompt a discussion on the allocation of time and workload for teachers, irrespective of their location in rural or urban areas.

Evaluation of morphological parameters, PLR and NLR inflammation indicators in patients with long-term COVID-19 of mild and severe complexity
Authors: Stróż Samuel , Kosiorek Piotr , Zbroch Edyta , Mikołuć Bożena , Stasiak-Barmuta Anna
Published: April 2024

Introduction

COVID-19 can have long-lasting effects, but the effects on blood parameters and inflammation are poorly understood. The aim of this study was to evaluate morphological and inflammatory markers in long-term COVID-19 patients.

Aim

To evaluate complete blood count, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and morphology in mild versus severe long COVID-19.

Material and methods

In total, 39 long COVID-19 patients were stratified into mild (n = 25) and severe (n = 14) groups. Blood counts, NLR, PLR were measured. Cell morphology was analysed. ROC curves were used to determine biomarker thresholds. Survival was assessed using Kaplan–Meier curves.

Results and discussion

Severe patients had lower leukocytes but higher neutrophils, indicating greater inflammation. NLR and PLR were significantly increased in severe patients compared to mild patients (NLR 12 vs 8; PLR 140 vs 100). NLR and PLR were higher than in controls, confirming their utility as inflammatory markers. NLR and PLR effectively discriminated between mild and severe disease. High NLR and PLR predicted poorer prognosis. Altered leukocyte morphology such as cytoplasmic vacuolization correlated with severity.

Conclusions

NLR and PLR are promising biomarkers for assessing severity of long COVID-19, while morphological changes in blood cells provide additional evidence of inflammation. Further studies in larger populations are warranted.
NURTURING CREATIVITY IN NON-ART-SPECIALISED PROSPECTIVE TEACHERS: A CASE STUDY
Authors: Lakhyani Susmita
Published: April 2024

Theoretically, art has been given a place in the school curriculum, but it is considered a fringe subject. This was also observed in prospective teachers with specialisations other than art, and likewise, they were reluctant to draw or paint. There is a need to understand the underlying issues and fill the gaps. This will help in prospective teachers’ personality development. In addition, they will help promote art in their schools, which they will join after finishing teacher training, which can pave the way for art-integrated teaching envisioned in National Education Policy 2020. This study aims to examine prospective teachers’ understanding of art and attitudes towards art as a subject, as well as the experiences that shaped them. It also attempts to organise an art workshop to see if it can help bridge the gap in the prospective teachers' understanding of art. For the study, 300 prospective teachers with specialisations other than art were taken as participants. Questionnaire was followed by a painting activity. Qualitative analysis highlighted the issues and gaps. It reflected participants' misconceptions of art, fears, and disinterest in art, as well as a discouraging school and home environment. It also reflected the issues in the teaching and learning process: a lack of trained art teachers and art being in the curriculum just in theory. The analysis was followed by organising the art workshop, focusing on bridging the gaps. Participants created artwork, and its qualitative analysis expressed values, showed growth in their understanding of art, and reflected participants' joy in its creation, aligning with art education's aim as mentioned in the National Curriculum Framework for School Education 2023.It is concluded that there are issues and challenges, and art workshops can bridge the gap in prospective teachers’ understanding of art. Consequently, art is essential to "teacher education" and can facilitate art-integrated learning, as outlined in the NCFSE 2023.

Published: April 2024

Tujuan dari penelitian ini adalah untuk mengevaluasi dan menguji hubungan antara tekanan anggaran dan risiko bencana, serta untuk menguji pengaruhnya terhadap kualitas lingkungan. Dalam penelitian ini, metode kuantitatif digunakan untuk mencapai tujuan penelitian. Populasi penelitian ini adalah seluruh pemerintah kabupaten dan kota di Provinsi Aceh. Dengan menggunakan teknik sampling jenuh dan data sekunder ditetapkan sampel penelitian. Laporan bencana dari Badan Penanggulangan Bencana Aceh dan laporan keuangan dari pemerintah daerah menjadi dasar metode dokumentasi data ini. Setelah pengumpulan data, SmartPls 3 digunakan untuk menganalisis data menggunakan PLS Structural Equation Modeling (SEM). Berdasarkan temuan analisis SEM PLS, risiko bencana berdampak signifikan terhadap kualitas lingkungan. Namun tekanan fiskal tidak banyak berpengaruh terhadap keadaan lingkungan. Demikian pula, tidak ada hubungan yang jelas antara risiko bencana dan tekanan fiskal. Temuan uji mediasi menunjukkan bahwa tekanan fiskal tidak dapat memoderasi hubungan antara kualitas lingkungan dan kemungkinan terjadinya bencana. Dengan memasukkan teknik pengurangan risiko bencana ke dalam keuangan daerah dengan tujuan menjaga stabilitas keuangan daerah, maka kontribusi penelitian ini diyakini akan membantu semua pihak yang berkepentingan dalam meningkatkan kualitas lingkungan hidup.

Producción científica en investigación sobre avances terapéuticos de la Enfermedad de Peyronie durante los últimos 62 años. Un análisis bibliométrico
Authors: Sandoval-Ojeda Juan Manuel , Celis-Camargo Laura
Published: April 2024

Introducción. La enfermedad de Peyronie es una malformación adquirida del pene, originada por la deposición de placas fibróticas en la túnica albugínea. La prevalencia en Estados Unidos oscila entre el 0.39% y 11.8%, en Europa 8.9%, en Latinoamérica no existe un porcentaje puntual de prevalencia actual debido a la escasez de reportes de esta patología. Este análisis bibliométrico busca describir la evolución terapéutica de la Enfermedad de Peyronie en la literatura de los últimos 62 años, así como la distribución geográfica de estas publicaciones. Metodología. Estudio observacional, descriptivo, un análisis bibliométrico desde 1957 hasta 2019, utilizando GoPubMed y FABUMED. Resultados. Se obtuvieron 721 referencias sobre tratamiento quirúrgico en enfermedad de Peyronie, con un aumento de la producción científica a lo largo del periodo de estudio. The Journal of Urology fue la revista con mayor cantidad de publicaciones, el 57.9% dentro de la categoría de artículo científico. El país líder fue Estados Unidos con 191 publicaciones. Discusión. Existe poca literatura sobre los avances terapéuticos para el tratamiento de enfermedad de Peyronie, lo que dificulta la comparación de las investigaciones a lo largo de los años en diferentes zonas del mundo. La investigación en Latinoamérica es escasa. Conclusión. La investigación sobre el tratamiento quirúrgico en enfermedad de Peyronie muestra un patrón ascendente en la productividad científica durante los años estudiados. Los países con mayores ingresos económicos son de mayor desarrollo en el tema y en menor medida regiones con recursos limitados. El análisis evidencia la importancia de aumentar producción científica en Colombia, así como estimular la investigación sobre este tema, ya que existen muy pocas publicaciones sobre la evolución del tratamiento quirúrgico para esta enfermedad.

Published: April 2024

Complete radial nerve palsy results in a lack of extrinsic extensors of the wrist, ﬁngers and thumb. The optimal treatment of persistent hight radial nerve palsy is tendon transfer, which leads generally to acceptable results with better extension of the ﬁngers and ability to grasp large objects. There are a multiple techniques of tendon transfers from a single to multiple one generally three tendons, however a single flexor carpi ulnaris tendon (FCU) transfer has some advantages, including simplicity, shorter operation time, less morbidity and less surgical scars, which can be important in some patients, particularly women. We present a case report of single tendon transfer of the FCU to the digital extensors for high radial nerve palsy secondary to closed diaphyseal humeral fracture.
Inflammatory Patterns in the Prostate Gland and Serum Cytokine Activities in Primary Adenocarcinoma of the Prostate in Port Harcourt, Nigeria
Authors: Ukamaka Chinelo Ogbonnaya  , Monday Komene Sapira
Published: April 2024

Introduction: Chronic inflammation and pro-inflammatory cytokines such as (1L-6 and TNF-α) have been implicated in prostate carcinogenesis and metastasis. This study aims to evaluate serum concentrations of IL-6 and TNF-α, and to determine their association with clinicopathological patterns of prostate cancer in affected patients. Materials and Methods: Ninety (90) patients with histologically diagnosed prostate cancer (PCa), treated at the Urology Division of the University of Port Harcourt Teaching Hospital (UPTH), Nigeria were involved in this study. The enzyme-linked immunosorbent assay (ELISA) technique was used to assay cytokines (IL-6 and TNF-α), and serum PSA. Gleason Scores were categorized as well differentiated (GS of ≤ 6), moderately differentiated (GS = 7), and poorly differentiated (GS 8-10). Results were analyzed with IBM SPSS version 20.0. Pearson’s correlation test was used to determine the correlation between the cytokines (IL-6 and TNF-α) and Gleason Scores. Results: The modal age group with PCa was 60-69 years. The mean age of patients was 68.788.26 years, and the mean serum PSA 93.2478pg/ml. Serum levels of IL-6 and TNF-α were 8.0pg/ml, 11.2pg/ml and (27.0±26.4pg/ml) respectively. Forty-six subjects had poorly differentiated PCa (GS 8-10); 17 moderately differentiated (GS 7); and 27 well differentiated (GS ≤ 6). Mean serum levels of IL-6, TNF-α and PSA (113.1ng/ml) were raised and found highest in those with poorly differentiated PCa. Conclusion: The observed correlation was positive but weak. The patients might have commenced undeclared anti-inflammatory drugs that depressed inflammation. However, a larger sample size would probably confirm the prognostic value of IL-6 and TNF-α in PCa subjects.

Coronavirus (COVID-19) is a global pandemic that has affected 229 countries and territories. Vaccines are one of the best ways to prevent and slow down transmission of COVID 19. Since students in school setting share teaching rooms, sport facilities, and other facilities like toilet and cafeteria, and have a higher number of social contacts, this study aimed to assess implementation of Vaccination against COVID 19 among preparatory school selected secondary preparatory schools in Akaki Kality Sub city, Addis Ababa, Ethiopia. Descriptive cross sectional study design using multistage random sampling technique was conducted among secondary school students in Akaki Kality sub city, Addis Ababa, Ethiopia from March 01 – 25, 2023. A total of 349 students proportionally allocated to five schools in Akaki Kality sub city were interviewed and focus group discussion were conducted with five catchment health center immunization focal persons. In this study, preparatory students had 44.6% knowledge and 17.5% practice regarding COVID 19 vaccination. Religion, residence, and the educational level of students’ parent were found associated with students’ knowledge on vaccination against COVID 19. Previous COVID 19 illness and knowledge of students were found to be associated with students’ vaccination practice against COVID 19. In comparison to other studies, relatively limited knowledge and poor practice were observed. Knowledge was found to be associated with students’ practices indicating the need for strengthening behavioral, risk communication and community engagement activities using religious leaders and different communication platforms. Additionally, to address vaccine related shortages, partnerships should be strengthened at different levels to enable direct purchases, utilization of group financing and donation options.

The concept of national security
Authors: Melikli Gunel
Published: April 2024

As is known, the standard of living and its well-being are determined by the political regime and the degree of participation of each citizen in public affairs. Political trends and electoral choices are measured by the level of human rights and freedoms. To achieve the right balance between the power of the state and existing human rights and freedoms, it is also necessary to implement social policies that has always confirmed its importance as an effective social factor in increasing the power of the country. The studies conducted in this area demonstrate that the relationship between government-implemented social policy and the national security threshold may vary.

A new genus of halictine bees from Central America (Hymenoptera: Halictidae)
Authors: Engel Michael S.
Published: April 2024

A new genus and species of halictine bees (Halictinae: Halictini: Mexalictina) is described and figured from a mid-elevation forest in northwestern Costa Rica. Meliamelitta vulcanus gen. and sp. n. is allied to Mexalictus Eickwort but differs in the structure of the labral
basal elevation, the obtuse epistomal sulcus, the elongate mandibles, the pectinate inner metatibial spur, the unique pterostigma, and the sculpturing of the basal area of the propodeum, among other features. A key is appended to the genera and subgenera of Mesoamerican, Central American,
and Caribbean Halictinae to facilitate the recognition of the genus.
From small beginnings... population explosions of migrant Belenois aurota (Fabricius) (Lepidoptera: Pieridae) in Türkiye, with rare observations in Syria and a first record for Cyprus

Published: April 2024

Incursions of Belenois aurota (Fabricius, 1793), a vigorous, tropical migrant pierid, have become more common in recent years in countries of the southern Levant, with rare appearances in south-eastern Türkiye. Here, we report on the species presence in other Levant countries
of the eastern Mediterranean, including Mediterranean Syria and, for the first time, in Cyprus, on which island B. aurota was discovered in 2023. We also report on experiences in south-eastern Türkiye, where, during the same autumn period, extensive breeding resulted in at least
three local broods leading to significant population irruptions and dispersal. Likely migration routes via the Jordan Rift Valley System into countries of the Levant are discussed, and we introduce an additional migratory route east of the Lebanon, Anti-Lebanon and Silsilat al-Jib āl
as-Sāhilīyah (Latakia) mountain ranges, not previously recognized to our knowledge. The value of the Tigris River as a conduit for migrant butterflies from the Middle East into the provinces of south-eastern Türkiye had previously been documented and is again well illustrated
by numerous observations in south-eastern Türkiye along the river's route south from its origins in the mountains of eastern Türkiye. Although B. aurota is recognized as an obligate migrant, it is considered that 2023 weather systems assisted the arrival of the species
into the northern Levant and south-eastern Türkiye.
Characterisation and Calibration of Multiversal Models
Authors: Cantone Giulio Giacomo , Tomaselli Venera
Published: April 2024

The Multiverse is a framework to design multi-model estimation where data are fit on many connected specifications of the same abstract model instead of a singular or a small selection of specifications. Differently from canonical multi-model, in Multiverse the probabilities of the specifications to be included in the analysis are never assumed independent of each other. Grounded in this consideration, this study provides a compact statistical characterisation of the process of elicitation of the specifications in Multiverse Analysis and conceptually adjacent methods, connecting previous insights from meta-analytical Statistics, model averaging, Network Theory, Information Theory, and Causal Inference. The topic of calibration of the multiversal estimates is treated with references to the adoption Bayesian Model Averaging vs. alternatives. In an application, it is checked the theory that Bayesian Model Averaging reduces error for well-specified multiversal models, but it amplifies it when a collider variable is included in the multiversal model. In well-specified models, alternatives do not perform significantly better than Uniform weighting of the estimates, so the adoption of a gold standard remains ambiguous. Normative implications for misinterpretation of the epistemic value of Multiverse Analysis and the connection of the proposed characterisation and future directions of research are discussed.
