Phenomena of Discourse Marker Use of Bilingual Children and Implications for Heritage Language Education
Authors: Kim Ihnhee
Published: May 2022

The present study explores the use of a discourse marker (DM) in dyadic talks of Korean-American bilingual schoolchildren. Using a corpus-driven analysis, this study demonstrates that the core function of the DM is to convey thinking processes, which is different from that of Korean monolingual children's data. That is, bilingual children use the DM for their own communicative needs in bilingual conversation. In-depth analysis further reveals evidence of incomplete first language acquisition that may result from an imbalance between L1 and L2 language education. Therefore, this study calls attention to how educators can best assist heritage language learners in developing pragmatic competence in the home language. Implications for heritage-language development and education are further discussed.
A Proposal for Advanced Level Korean Curriculum
Authors: Wang Hye-Sook
Published: May 2022

The main goals of this paper are to reflect upon the current practices of the advanced level Korean language teaching in American colleges and universities and to propose a curricular model for fourth and fifth year courses. Following a review of relevant literature and the status quo of advanced level teaching, a course proposal was made with a brief description of theoretical framework. The proposed course is built upon the Content-based Instruction (commonly known as CBI or CBLT) model as a main principle and genre-based approach. It was made based on the mega-theme of 'conflict' as a keyword or important concept to comprehend various aspects of Korean culture and society. This year-long course is designed to ensure coherence of themes covered and in-depth understanding of core issues of Korean culture and society. Advantages of this model as well as challenges and practical tips associated with implementing this model are also discussed.

Highlights

Background:

Peripheral intravenous venous catheters (PIVCs) are associated with a postinsertion failure incidence of 40%, yet the common maintenance and preventive strategy of saline flushing is poorly understood at a physiological level.

Methods:

We developed a human model of bilateral cephalic vein cannulation to study the impact of varied PIVC flushing frequency (high frequency, HF; low frequency, LF) over 5 hours on catheter failure (primary outcome), coagulation, platelet aggregation, and local tissue injury. Ultrasound was used in a subset to assess vascular diameter/catheter to vein, blood flow velocity, and thrombus formation.

Results:

Out of 34 catheters in 17 adult participants, 1/17 (6%) LF catheters failed, which was not significantly different from HF catheters (0/17). Platelet function, activated partial thromboplastin time, and tissue factor were also not different (P > 0.05). However, prothrombin time (PT) increased with HF versus LF after 5 hours (P < 0.05). Ultrasound demonstrated luminal thromboses in veins experiencing both HF (6/7) versus LF (5/7) conditions after 5 hours with nonsignificant changes in vascular diameter and blood flow velocity over time.

Conclusions:

Although no difference in PIVC failure was observed between HF and LF flushing conditions over 5 hours, greater flushing frequency increased PT time, suggesting delayed activation or consumption of extrinsic coagulation factors. This study also demonstrated feasibility in assessment of luminal thromboses, which were remarkably prevalent after PIVC placement, and changes in vascular diameter and blood flow. This manuscript illustrates that the development of a sensitive human model will be of great use for exploring the impact of interventions on reducing PIVC failure in the future.

Published: May 2022

El texto analiza la identidad de las familias campesinas del área rural del Municipio de Paipa (Colombia), que, además de producir queso desarrollan otro tipo de actividades: pecuarias, agrícolas, elaboración de amasijos, cultivo de frutales. A partir de sus narraciones y relatos se aprecian escenarios referentes a la experiencia vivida tanto en el territorio, en su entorno familiar, en los productos, en el mercado y en su hábitat. El proceso identitario se analizó desde dos perspectivas: la familia campesina como tradición y la actividad agropecuaria como forma de vida y sustento. La familia es la primera estructura de socialización y se constituye en el grupo primario donde el individuo interactúa desde que nace; en este contexto adquiere experiencias y valores que son importantes para la vida. Las actividades agropecuarias además de ser un aprendizaje, proporcionan el sustento a la familia campesina y desarrollan valores de solidaridad, adquieren saberes afines a la producción agrícola, ganadera y su relación con el mercado, como prácticas de supervivencia.
Políticas públicas de inclusão produtiva de agricultores familiares: entre continuidades e descontinuidades na agenda política brasileira
Authors: Sousa Diego Neves de
Published: May 2022

Como forma de apreender o referencial que orienta as políticas públicas para a agricultura familiar, procuramos compreender como os mediadores, classificados em cinco “mundos sociais” (extensionista, gestor, pesquisador, professor e movimentos sociais), identificam as políticas que mais tiveram foco na inclusão produtiva nas três últimas décadas (1990-2020). Para isso, utilizou-se da técnica de entrevista semiestruturada realizada com 80 mediadores sociais que atuam com os públicos da agricultura familiar no estado do Tocantins. Conclui-se que apesar da mudança no “referencial” das políticas governamentais com vistas a incorporar a noção de inclusão produtiva, este não coincide, na maioria das vezes, com as ideias e práticas dos mediadores envolvidos nos processos de intervenção sociotécnica junto aos diferentes grupos de agricultores familiares.
Estrategias productivas de familias productoras y su relación con la agroecología: estudio de casos en el centro oeste de la provincia de Buenos Aires (2020)
Authors: Giordani Gabriela , Cittadini Roberto Arnaldo
Published: May 2022

El modelo productivo de la agriculturización se extendió en la región pampeana. También, se desarrollaron alternativas como la agroecología. La hipótesis es que unidades familiares que adoptaron variantes productivas al modelo hegemónico lograron mantenerse en la producción. El objetivo es documentar y analizar las estrategias de cuatro familias productoras y su relación con el modelo de la agroecología. A partir de estudios de casos, se encuentra que no entraron en el modelo hegemónico y están cerca de lo que propone la agroecología. Se concluye que el tipo de unidad y su trayectoria promueven la elección de modelos alternativos.

The Educational Impact of Al-Azhar University in South Western Nigeria: A Case Study of Arabic-Islamic Schools in Yorubaland
Authors: Abdus Salam Yunus Olatoke , Bin Mohammad Saud
Published: May 2022

Pursuing education in Arab countries generates a controversy among indigenous and home-made scholars in Nigeria. Some believe that it is enough to pursue religious education within the country, while some others uphold the standpoint that Muslim students should pursue their studies in Arab countries like Al-Azhar. Hence, there is a lot of confusion and controversy about the impact of Al-Azhar University in Nigeria. However, this study aims to investigate the impact of Al-Azhar University in Cairo, Arab Republic of Egypt on Arabic-Islamic schools in the Yorubaland, Nigeria. This is done through investigation of its curriculum, scholarship, and sending of Al-Azhar's delegates to teach in Arabic-Islamic schools in Yorubaland, Nigeria. It discusses Islamic religious affairs and the role played by the Nigerian Muslim scholars in general and in the South Western Nigeria in particular. Furthermore, it addresses the argument bothering on the need to pursue religious education within and outside the country. This study also examines the difference between Al-Azhar educational system and the Nigerian Arabic- Islamic educational system and investigates the need for continuation or otherwise of Al-Azhar’s venture in the Nigerian Arabic- Islamic Schools. This study is both historical and analytical in nature. It used data gathered via primary and secondary sources and utilizes both qualitative and quantitative methods. Findings from this study revealed the suitability of Al-Azhar educational system for Nigeria. It also showed the continuous need to pursue Al-Azhar education by Nigerians. The need to introduce some Western courses into Al-Azhar educational curriculum to facilitate easy fitting of the graduates into Nigerian educational system also emanated from this study. The study recommends the completion of secondary education in Nigeria by intending Nigerians seeking Al-Azhar education in order to facilitate their usefulness in the Nigerian western-oriented educational system upon their return.

Published: May 2022

The aim of this study was to evaluate the effect of an enzymatic mixture on the increase of biogas production from lignocellulosic materials as rapeseed straw, maize waste, and wheat straw. For efficient application of the enzymatic mixture, conditions of its use were optimized regarding 50 °C, pH 7 and an enzyme dose of 0.25 % w/v. Biogas potential test confirmed positive effect of the enzymatic mixture on anaerobic digestion of already thermally and alkali pre-treated lignocellulosic materials, as significantly higher biogas production was observed after the enzymatic mixture addition for all monitored substrates. Addition of the enzymatic mixture to the most used substrate at biogas plants — maize silage, had also positive effect on biogas production during the biogas potential test. This fact was not proven during long-term operations of the reactors as the values of total cumulative biogas productions for the whole monitored period from reactors for anaerobic digestion of maize silage with and without addition of enzymatic mixture did not differ significantly.

Published: May 2022

Unmanned aerial vehicle (UAV) is a typical aircraft that is operated remotely by a human operator or autonomously by an on-board microcontroller. The UAV typically carries offensive ordnance, target designators, sensors or electronic transmitters designed for one or more applications. Such application can be in the field of defence surveillance, border patrol, search, bomb disposals, logistics and so forth. These UAVs are also being used in some other areas, such as medical purposes including for medicine delivery, rescue operations, agricultural applications and so on. However, these UAVs can only fly in the sky, and they cannot travel on the ground for other applications. Therefore, in this paper, we design and present the novel concept-based UAV, which can also travel on the ground and rough terrain as an unmanned ground vehicle (UGV). This means that according to our requirement, we can use this as a quadcopter and caterpillar wheel–based UGV using a single remote control unit. Further, the current study also briefly discusses the two-dimensional (2D) and three-dimensional (3D) SolidWorks models of the novel concept-based combined vehicle (UAV + UGV), together with a physical model of a combined vehicle (UAV + UGV) and its various components. Moreover, the kinematic analysis of a combined vehicle (UAV + UGV) has been studied, and the motion controlling kinematic equations have been derived. Then, the real-time aerial and ground motions and orientations and control-based experimental results of a combined vehicle (UAV + UGV) are presented to demonstrate the robustness and effectiveness of the proposed vehicle.

Authors: Ma Haoguang , Qin Hao
Published: May 2022

From the perspective of innovation ecology, the green innovation of core enterprises is a key to high-quality economic development. This paper researches BYD, makes a discussion on the evolution and characteristics of green innovation, and clarifies the driving force of green innovation of core enterprises in the green innovation ecosystem. In addition, the 2002–2019 green patent authorisation data of BYD is selected as the green output indicator of the core enterprise. And through testing the data, the findings are that the perturbation term ε is white noise, which meets the zero expectation E(εt
) = 0, and the same variance Var(εt
) = σ
2 and that there is no autocorrelation Cov(εt
, εs
) = 0, t ≠ s. The ARMA model is hence constructed for analysis. Through analysis, conclusions are drawn that when the core enterprises and other entities in the green innovation ecosystem collaborate to innovate, the complexity and dynamics could be found in the green innovation evolution process and that as an important driving force for green innovation, innovation input not only raises current green output but also facilitates future green output.

Published: May 2022

This study aimed to evaluate the growth and performance of genetically improved tilapia reared at different temperatures. Four hundred and eighty fingerlings of Genomar Supreme Tilapia, GST (8.39 ± 0.60 g) were equally separated into three indoor water recirculation systems maintained at 22, 26 and 30 ºC. Each of four tanks contained 500 liters with 40 fish per tank in natural photoperiod. The fish were fed ad libitum with the same feed for each growth phase, weighing the total feed supplied. After 30 min of feeding, leftover feed was collected, dried in an oven and weighed. Ten fish from each tank were weighed at days 1, 30, 60, 90, 120, 150, 180 and 210. Survival, weight gain, feed conversion and feed intake in each period were determined. Fish reared at 30 ºC and 26 ºC showed a higher specific growth rate than that of fish reared at 22ºC (P≤0.05). Feed intake increased along temperature and feed conversion and was poorest in fish reared at 26ºC (P≤0.05). Final fish weight estimates at day 210 by the Gompertz model were 597.84, 819.26 and 1079.39 g for 22, 26 and 30 ºC, respectively. At 30 ºC, fish had a higher absolute growth rate (7.76 g day−1) and lower weight (459.30 g) and age (95.85 days) at the inflection point. Tilapia at 22 ºC had a higher weight (539.57 g) and age (197 days) and lower absolute growth rate (4.52 g day−1). It was concluded that GST tilapia can potentially improve aquaculture in all Brazilian regions based on different rearing temperatures.

Probiotics can functionally improve fish wellbeing and are suggested as antioxidative agents to protect fish from xenobiotics toxicity. Herein, dietary Lactobacillus casei (IBRC-M 10,711) was included in the diets of goldfish (Carassius auratus) to protect against malathion toxicity. Fish (12.47 ± 0.06 g) were randomly allocated to six groups (triplicates), as follows: T1) control; T2) fish exposed to 50% of malathion 96 h LC50; T3) L. casei at 106 CFU/g diet; T4) L. casei at 107 CFU/g diet; T5) fish exposed to 50% of malathion 96 h LC50 + L. casei at 106 CFU/g diet; T6) fish exposed to 50% of malathion 96 h LC50 + L. casei at 107 CFU/g diet. After 60 days, goldfish fed T4 had the highest final body weight (FBW), weight gain (WG), and specific growth rate (SGR), and the lowest feed conversion ratio (FCR) among the groups (P < 0.05). However, the T2 group showed lower FBW, WG, and SGR and higher FCR than fish in T1 (P < 0.05). Fish in the T4 group had the highest blood total proteins, albumin, and globulin, while fish in T2 had the lowest levels (P < 0.05). Fish in the group T2 had the highest triglycerides, cholesterol, cortisol, lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) levels in the blood, while fish fed T4 had the lowest values (P < 0.05). The superoxide dismutase (SOD) and catalase (CAT) showed the highest activities in T3 and T4 groups, and the lowest SOD was seen in the T2 group, whereas the lowest CAT was seen in the T2, T5, and T6 groups (P < 0.05). Fish in the T5 and T6 groups had higher glutathione peroxidase (GSH-Px) activities than fish in T1 and T2 groups but T3 and T4 groups showed the highest values (P < 0.05). T2 group had the highest malondialdehyde (MDA) level, while T3 and T4 groups had the lowest MDA level (P < 0.05). Blood immunoglobulin (Ig) and lysozyme activity were significantly higher in T3 and T4 groups and lower in the T2 group than in the control (P < 0.05). The alternative complement pathway (ACH50) was significantly higher in T2, T3, T4, T5, and T6 groups than in the T1 group (P < 0.05). Skin mucus Ig was significantly higher in T3 and T4 groups and lower in the T2 group than in the control (P < 0.05). The highest lysozyme activity, protease, and ACH50 in the skin mucus samples were in the T4 group, while the lowest values were in the T2 group (P < 0.05).

Published: May 2022

World wide, breast cancer is the most common malignancy in women. Despite an increased incidence of this cancer, the mortality rates have been maintained at the same level. This is due to the continuous development of therapeutic, as well as diagnostic methods because appropriate, effective treatment is dependent on accurate diagnosis. At the same time, the success is that more and more patients undergo breast- and axillary lymph nodes-sparing surgeries, therefore, determining the initial advancement stage of breast cancer is absolutely essential for ensuring proper therapy. This is a review of current guidelines for both early and advanced stages of breast cancer diagnostics. The principles described are largely based on the work of the European School of Oncology (ESO) and the European Society for Medical Oncology (ESMO). The review includes the rule of imaging studies, especially mammography screening and histopathological evaluation with molecular classification of breast cancer.
MicroRNA expression biomarkers of chronic venous disease
Authors: Zalewski Daniel , Chmiel Paulina
Published: May 2022

Chronic venous disease (CVD) is a common disease caused by hemodynamic disorders of the venous circulation in the lower extremities. The clinical image of this disease is complex and includes such signs as telangiectases, varicose veins, leg edema and skin changes, usually accompanied with ache, pain, tightness, heaviness, swelling and muscle cramps of legs. Venous ulcers develop in the advanced stages of the disease and lead to significant impairment of patient abilities and reduction of the quality of life. CVD is diagnosed based on physical and image examinations, and main treatment options include compression therapy, invasive treatments like endovenous ablation and foam sclerotherapy, as well as pharmacotherapy. Currently, there is no biochemical and molecular biomarkers utilized in diagnosis or treatment of CVD. With regard to this situation, one of the most investigated fields for identification of disease biomarkers is microRNA (miRNA). These constitute a pool of small, non-coding RNAs that play crucial roles in maintaining cellular homeostasis through posttranscriptional regulation of genes expression. Dysregulations of miRNA expression profiles have been found in patients with various diseases, and this situation provides information about potential miRNA signatures involved in pathophysiology. In this review, the studies focused on investigations of miRNA expression patterns in patients with CVD were collected. The performed literature analysis provides contemporary knowledge in the field of miRNA-dependent mechanisms involved in the etiopathogenesis of CVD and shows gaps that need to be filled in further studies.
Pharmacological Treatment of Chronic Congestive Heart Failure

Published: May 2022

Chronic congestive heart failure is a clinical syndrome based on the progressive deterioration of contractile (systolic) heart function due to structural or functional disorders. The incidence of the disease increases with age, so the prevalence in people older than 75 years is greater than 10%. Due to the different clinical presentation, the pharmacological approach to the patient is individual, and most patients are treated on an outpatient basis, according to the guidelines taken from the recommendations of professional associations. Hospitalization is necessary in severe forms of CHF or acute exacerbations. Patients with severe hemodynamic disturbances due to acute CHF require treatment in intensive care units, due to specific cardiovascular therapy, respiratory support and vital functions monitoring. Individualized, stepwise and rational pharmacological therapy achieves significant symptomatic and functional improvement in most patients.

More knowledge about the impact of medication on driving are indicative of a lower likelihood of having a motor vehicle crash. The aim of this study was to investigate knowledge of professional drivers about the influence of driving impairing medicines in Serbia and Bosnia and Herzegovina.

This multicenter cross-sectional study was conducted in 6 cities in Serbia and Bosnia and Herzegovina, during first trimester of 2017, with 221 professional drivers, using questionnaire with 35 statements, where participants expressed their agreement according to Likert scale, from completely disagree to completely agree.

The average score related to the drivers’ knowledge was 131,58 (range from 49 to 175), 22,6% were unaware that some medicines may influence psychophysical abilities and ability to drive. A high percentage of participants in the study don’t know that a negative impact on the driving ability can be the result of the use of medicines from groups for which it is unexpected to have such effects, medicines that are dispensed without a medical prescription, herbal remedies, dietary supplements and medicines that affects eyesight or hearing. More than half didn’t know that medicines labeled with warning symbols Δ, ▲ and § are not allowed to be used immediately before or during driving.

Professional drivers’ knowledge about driving impairing medicines is not satisfactory. Labeling system of these medicines is inadequate. These findings could help to identify drivers, who are at increased risk for using potentially impairing medicines, to inform and educate them, and to prevent driving under the influence of medicines.
Buzzword – Foreign word – Keyword: The Innovation term in german media
Authors: Schützeneder Jonas
Published: May 2022

The term "innovation" has been a buzzword in public communication for decades. Between advertising, products and processes, various dimensions run with and against each other. This study is an attempt to develop a more systematic approach to the concept of innovation and therefore looks at the german media coverage of innovation. The time period of 20 years and the focus on five leading newspapers and magazines made it possible to obtain a total sample of 127,182 articles, which were investigated through an automated content analysis. This provides a specific view of the context, actors and relationships that have developed around the concept of innovation. It shows that innovation is interpreted as the central currency of economic perspectives, represents a weighty evaluation criterion for politicians and, above all, is used as a permanent evaluation of Germany as a business location in international comparison.
Cyclical IPR-public Grant Engine Driving R&D Innovation in Small Research-intensive Private Enterprises
Authors: Sinadinos Christopher
Published: May 2022

A reciprocal relationship has been documented between registering formal intellectual property rights (IPR), obtaining public grants, and undertaking publicly subsidised R&D innovation projects. Focusing on SMEs as key beneficiaries of such grants, this paper provides an original conceptual framework to rationalise this relationship based on the core criteria to obtain and successfully exploit both grants and formal IPR. R&D innovation grants from several European countries display common elements conducive to securing formal IPR status. Novel observations of several European SMEs demonstrate an innovation engine cycling between formal IPR management and publicly subsidised R&D innovation, sometimes for multiple cycles over several years. This was seen for varying grant sizes, technological sectors, and geographical locations. The framework and observations presented herein are of potential interest to research-intensive SMEs, public grant bodies, and professional service providers for public subsidies and IPR management.

Published: May 2022

Snake venoms have been fervently studied for decades for two reasons: 1) high death rate due to snake bites; 2) numerous components of snake venoms prove useful in medicine and treatment of diverse pathologies. Snake venom phospholipases A2 are among the most aggressive toxic proteins often playing the main role in immobilization and killing of snakebite victims. These enzymes catalyze the hydrolysis of glycerophospholipids to produce lysoglycerophospholipids and free fatty acids. But the diversity of phospholipase A2 effects is not limited to their catalytic action. In this review (Part 1), we describe the features of the structure and properties of Viperidae snake venom phospholipase A2 .
