Pub Date : 2023-07-15 DOI: 10.60087/jklst.vol2.n2.p54
Domonkos Frigyes Török
Over the last decade, the global demand for sparkling wine has surged by 40%, with Hungary being a pivotal player in this industry due to its rich history in wine production. Given the rising health consciousness among consumers and the established health benefits associated with moderate wine consumption, understanding the polyphenolic composition of these wines has become imperative. In this study, a spectrum of analytical and sensory tests were performed on a variety of 2017 vintage traditional method sparkling wines to delineate their polyphenol content, which plays a crucial role in defining the wine's taste and potential health benefits. Through meticulous analysis covering parameters such as leucoanthocyanin, catechin, colour intensity, and total antioxidant capacity, alongside routine analyses examining factors such as alcohol content and pH level, we aimed to offer a granular understanding of the characteristics defining both domestic and foreign traditional method sparkling wines. Our data revealed a remarkable diversity in the world of sparkling wines, with Hungarian variants standing toe-to-toe in terms of quality with their foreign counterparts. We discerned significant variability in the phenol content across different samples, and identified a general trend of lower polyphenol content in sparkling wines compared to still wines. This study not only underscores the commendable quality of Hungarian sparkling wines but also accentuates the vital role of polyphenols, advocating for a deeper exploration into this aspect to cater to the health-conscious consumer market and facilitating the continued growth of the Hungarian sparkling wine industry in the booming global market.
在过去的十年中,全球对起泡葡萄酒的需求激增了 40%,匈牙利因其丰富的葡萄酒生产历史而在该行业中占有举足轻重的地位。鉴于消费者健康意识的提高以及适量饮用葡萄酒对健康的益处,了解这些葡萄酒的多酚类成分已成为当务之急。在这项研究中,我们对多款 2017 年份传统酿造法起泡葡萄酒进行了一系列分析和感官测试,以确定其多酚含量。通过对白花青素、儿茶素、颜色强度和总抗氧化能力等参数的细致分析,以及对酒精含量和 pH 值等因素的常规分析,我们旨在对国内外传统酿造法起泡葡萄酒的特点有一个细致的了解。我们的数据揭示了世界起泡葡萄酒的显著多样性,匈牙利起泡葡萄酒的质量与国外同类产品不相上下。我们发现不同样品中的酚含量存在很大差异,并发现起泡葡萄酒中的多酚含量普遍低于静止葡萄酒。这项研究不仅强调了匈牙利起泡葡萄酒值得称赞的品质,还突出了多酚的重要作用,主张对这方面进行更深入的探索,以迎合注重健康的消费市场,促进匈牙利起泡葡萄酒行业在蓬勃发展的全球市场中继续增长。

The Impact of Biological Gender Exploring  on L1 Negative Transfer in English Preposition Learning 生物性别探索对英语介词学习中母语负迁移的影响
Tran Tin Nghi
This study investigates the influence of biological gender on L1 negative transfer in learning English prepositions. Interviews were conducted with 12 English language learners, revealing that males performed better in spatial prepositions but struggled with other types. A mixed-methods approach was used, combining qualitative and quantitative research. Female participants demonstrated higher performance, and the study was conducted in Luxembourg, a multilingual country. Ethical considerations were addressed, achieving a 91.08% response rate. Results indicated females generally outperformed males in prepositional accuracy. Language transfer from L1 impacted preposition acquisition, with replacement errors being common. Females showed greater syntactic maturity, while males exhibited advanced linguistic skills. Stylistic differences in writing styles were observed. The study highlights the influence of gender in language acquisition and contributes to understanding gender disparities in second language learning.

A Review on Structure and Blood Lipid Reducing Activity of Fucoidan 岩藻多糖结构及降血脂活性研究进展
Lam The Hai
Seaweed is rich in biologically active substances, and fucoidan is of most interest because of its diversity in activity and structure. In Vietnam, 3 out of 10 adults have high blood cholesterol (accounting for 39%), and over 50% of women aged 50-65 have hypercholesterolemia. Blood fat index is one of the health indicators, especially in people who are overweight, obese, or have cardiovascular disease. Too much fat in the blood will lead to the risk of dangerous diseases such as myocardial infarction, coronary artery disease, and cerebrovascular accident. Currently, many fucoidan products have been launched. Therefore, the paper presented fucoidan with its structure and lipid-lowering activity so that people can use them in decrease the disease

Abstract: Background: In a country, many girls may forcefully be married off at an early age where they might have no hand in it. But the thought and view they carry throughout their lifetime can be resembled in the lives of their children too and can proclaim plenty of the country problems, especially receiving improved antenatal care (ANC). A woman or a prospective mothers view of her husband beating her tells a lot about a country people view, and preferred age of marrying by a woman can also exhibit her attitude toward her rights and goals. However, limited research has focused on understanding women perspectives on their rights and their relation with ANC quality in Bangladesh. The findings of this study will contribute to a deeper understanding of women perspectives on their rights and the barriers they face in accessing quality ANC. Objective: This study aims to investigate the view of Bangladeshi women toward their own rights and the impact on their access to improved ANC. Method: To address this gap, a binary logistic regression model was employed by analyzing in IBM SPSS Statistics 25 using Bangladesh Demographic and Health Survey (BDHS) 2017-18 data. The study recruited a diverse sample of women from various social backgrounds, beliefs, and geographical locations in Bangladesh. Result: It was spotted that a small percentage (6.6%) of women in Bangladesh were under proper ANC coverage. The women who did not justify domestic violence were 1.231 times more likely to be under ANC coverage in Bangladesh than those who justified domestic violence in the adjusted model. Moreover, women with no education were .048 times less likely to be under ANC coverage than women with higher education. Women who were not exposed to media were .099 times less likely to be under ANC coverage than those who were exposed to media. Unfortunately, almost one-fifth of all Bangladeshi women (19.6%) justified being beaten by their husbands. Conclusion: Entitlements of women enable them to actively engage in their own healthcare programs, leading to improved health outcomes for both mother and child. Through targeted awareness campaigns, educational initiatives, and policy advocacy, Bangladesh can create an environment where women are aware of their rights and have access to quality ANC services. By ensuring their rights are respected, a society that values reproductive health and the well-being of women and children can strive.
摘要:背景:在一个国家,许多女孩可能在很小的时候就被强行嫁出去,而她们可能没有参与其中。但他们一生的思想和观点也可能与他们的孩子的生活相似,并且可以表明国家的许多问题,特别是接受改善的产前保健(ANC)。一个女人或一个准妈妈对丈夫殴打她的看法反映了一个乡下人的看法,一个女人选择的结婚年龄也可以显示她对自己的权利和目标的态度。然而,有限的研究集中于了解孟加拉国妇女对其权利的看法及其与非国大质量的关系。这项研究的结果将有助于更深入地了解妇女对其权利的看法以及她们在获得高质量的非农业生产方面面临的障碍。目的:本研究旨在调查孟加拉国妇女对自身权利的看法及其对其获得改进的ANC的影响。方法:利用2017-18年孟加拉国人口与健康调查(BDHS)数据,在IBM SPSS Statistics 25中采用二元逻辑回归模型进行分析,以解决这一差距。这项研究在孟加拉国招募了来自不同社会背景、信仰和地理位置的不同女性样本。结果:发现孟加拉国有一小部分(6.6%)妇女得到了适当的ANC覆盖。在调整后的模型中,孟加拉国没有证明家庭暴力的妇女比证明家庭暴力的妇女受到ANC覆盖的可能性高1.231倍。此外,与受过高等教育的妇女相比,未受过教育的妇女获得非国大保险的可能性低0.048倍。未接触媒体的妇女受到ANC报道的可能性比接触媒体的妇女低0.099倍。不幸的是,几乎五分之一的孟加拉国妇女(19.6%)认为被丈夫殴打是合理的。结论:妇女的权利使她们能够积极参与自己的保健方案,从而改善母亲和儿童的健康状况。通过有针对性的提高认识运动、教育倡议和政策宣传,孟加拉国可以创造一个环境,使妇女意识到自己的权利,并获得优质的非国大服务。通过确保妇女和儿童的权利得到尊重,一个重视生殖健康以及妇女和儿童福祉的社会就能够努力奋斗。

Effectiveness of technology in Open Distance Learning 开放远程教育中技术的有效性
Pub Date : 2023-04-30 DOI: 10.60087/jklst.v02.n01.p70
Patrick Zingisa Msekelwa
Technology was gradually embraced by distance education institutions to interact and instruct their diverse student body. To reach students in far-flung locations, the University of South Africa (Unisa) has embraced the Open Distance and E-learning (ODeL) paradigm. The digital gap is a problem as technology advances because it makes it difficult for pupils to access the Internet. The study went over the literature with a particular emphasis on the usefulness of technology in ODeL. To thoroughly examine the case, the study has chosen a qualitative research methodology. To analyze the data acquired from students enrolled in ODeL courses, the study has utilized a community of inquiry structure. The study made use of the interpretative paradigm, which holds that reality is a multi-layered, complicated phenomena that may be interpreted in several ways. The study is comprehensive in character since a qualitative research technique using a case study design method was chosen most appropriate for it.  Twelve individuals were chosen by the researchers from two Unisa regional offices in the Eastern Cape Province using a purposive sample technique. The participants were questioned about their opinions and experiences with using technology during semi-structured interviews. Thematic analysis, a method of finding themes within qualitative data, was used to analyze the acquired data. The results showed that students who used technology well were better communicators, had better grades on their assignments, and fared well on tests
远程教育机构逐渐采用技术来与不同的学生群体进行互动和指导。为了接触到偏远地区的学生,南非大学(Unisa)采用了开放远程和电子学习(ODeL)模式。随着科技的进步,数字鸿沟成为了一个问题,因为它使学生难以上网。该研究回顾了文献,特别强调了技术在ODeL中的有用性。为了彻底检查的情况下,研究选择了定性研究方法。为了分析从参加ODeL课程的学生那里获得的数据,本研究采用了一个社区的调查结构。该研究使用了解释性范式,该范式认为现实是一个多层的、复杂的现象,可以用几种方式解释。本研究是综合性的,因为使用案例研究设计方法的定性研究技术是最适合它的。研究人员从东开普省的两个Unisa区域办事处中选择了12个人,采用了有目的的抽样技术。在半结构化的访谈中,参与者被问及他们对使用技术的看法和经验。主题分析是一种在定性数据中寻找主题的方法,用于分析所获得的数据。结果表明,善于使用科技的学生是更好的沟通者,在作业中取得了更好的成绩,在考试中表现也很好
