Authors:   Associate Professor of English, Hankuk University of Foreign Studies, Seoul, South Korea, Hull Todd
Published: September 2023

Dictation is an effective tool in facilitating foreign language acquisition. But traditional dictation, while having some benefits for acquiring a foreign language, was neither engaging for students nor did it focus on the actual, real world communication that is fundamental to the communicative approach of today. Dictogloss introduced communicative dictation and has been used widely in classrooms around the world. But, however dictation is done in the classroom, it can 1) feel to adult learners at least somewhat like something for children and 2) even when designed for adults, typical dictation topics can be perceived to be more at home in a language institute than an academic university setting. This paper will summarize types of traditional dictation, outline the characteristics of dictogloss and how it is an improvement on traditional dictation, review some of the research on its additional benefits for acquiring a foreign language, and suggest how it can be used at the university level.

Published: September 2023

This study aims to analyze the feasibility of investment in the framework of implementing cooperation in the utilization of assets or goods owned by the local government using descriptive semi-qualitative methods. In conducting the analysis, researchers used the investment feasibility approach is the Net Present Value (NPV) method to measure the present value of the expected net cash flow of a project, Internal Rate of Return (IRR) is the discount rate that makes the NPV of the project zero, Profitability Index (PI) to measure the relationship between the present value of net cash flow and initial investment and Payback Period (PP) is the period of time required to recover the initial investment from net cash flow. In addition, in order to develop tourism potential, researchers use the Segmenting Targeting Positioning (STP) strategy, which is an approach used by companies to understand their markets better and develop effective marketing strategies. The results prove that the cooperation plan for the utilization of assets or goods owned by the local government with partners as investors is feasible because it produces additional net cash flow during the project with a positive present value, and the rate of return on the net value of cash flow during the project is greater than the BI Rate and the benefits received from tourism development are more profitable than the costs incurred during the project. In addition, the time span required for payback is shorter than the project period. As an effort to increase tourism revenue and visitors, the Segmenting Targeting Positioning strategy is used.

Published: September 2023

Large-scale cyanobacterial harmful algal blooms (cHABs) in Lake Okeechobee, Florida, and connected waterways routinely impair water resources. This study conducted a field demonstration of a peroxide-based algaecide in 2020 in the Pahokee Marina on Lake Okeechobee to evaluate the algaecide’s suitability for near-future operational implementation. Within minutes of treatment, rapid oxidation of cHAB cells occurred in the form of bleaching and cell lysis. On average, levels in the treatment area decreased by 4 hours after treatment (HAT) and remained low out to 24 HAT: chlorophyll decreased 87%, phycocyanin decreased 85%, total microcystin levels decreased from 50 μg L−1 to 4 μg L⁻¹ at 4 HAT and then increased to 11 μg L⁻¹ by 24 HAT, hydrogen peroxide concentrations averaged 6.1 mg L⁻¹ 0.5 HAT and then dropped below detection limits by 24 HAT, and Microcystis spp. cell densities decreased at 4 HAT in all but four sampling sites. However, inflows of cHAB-infested lake water in some portions of the treatment area resulted in lack of control at these sites. Because of their vulnerability to influxes of cHABs from surrounding nontreated waters via water-exchange processes driven by wind-induced surface currents, future applications must therefore consider treatment area size.

Published: September 2023

O carvão mineral trouxe bastante desenvolvimento para a Região Sul do Estado de Santa Catarina, porém, resultou em degradações ambientais que a natureza levará anos para regenerar. Com o intuito de preservar os recursos hídricos e a vegetação existente na sub bacia hidrográfica do Rio Maior, o Município de Urussanga criou, por meio da lei municipal nº 1.665/1998 a Área de Proteção Ambiental (APA) do Rio Maior. No entanto, após mais de quatro décadas de sua criação, a APA do Rio Maior sofre com o descaso do poder público municipal, relativo a seus recursos hídricos, altamente impactados pelas atividades carboníferas, devido à ausência de plano de manejo e zoneamento ambiental, atrasado em mais de 20 anos. Assim, este artigo tem por finalidade analisar criticamente a importância da gestão territorial na preservação de áreas de proteção ambiental, utilizando como estudo de caso a APA do Rio Maior, localizada no município de Urussanga, em Santa Catarina e indicar medidas que possam auxiliar o poder público na tomada de decisão acerca da mesma. Após análise, percebeu-se que os gestores e órgãos públicos negligenciam a execução das Leis e não conseguem garantir para sua população no futuro o cumprimento de uma função social básica relativa ao abastecimento de água.
Identification of Key Biomarkers in RF-negative Polyarticular and Oligoarticular juvenile idiopathic arthritis by Bioinformatic Analysis
Authors: liu yun , tang xuemei
Published: September 2023

Objective
Juvenile idiopathic arthritis (JIA) is a broad term used to describe arthritis of unknown origin. JIA commonly persists into adulthood, often causing substantial morbidity, such as restricted joint function, which can lead to challenges in employment and independence. This study aims to identify diagnostic biomarkers and investigate the role of immune cells in the pathogenesis of rheumatoid factor-negative polyarticular juvenile idiopathic arthritis (RF-negative pJIA) and oligoarticular juvenile idiopathic arthritis (oJIA).
Methods
We retrieved a JIA dataset from the GEO database and conducted an analysis of differentially expressed genes (DEGs). Subsequently, functional enrichment analysis was performed on the DEGs. Weighted gene coexpression network analysis (WGCNA) was utilized to identify key modules. Additionally, we constructed a protein‒protein interaction network to identify hub genes that serve as signature genes. Furthermore, we employed CIBERSORT to classify immune cell infiltration.
Result
s From the GSE20307 dataset, we identified a total of 1438 DEGs in RF-negative pJIA and 688 DEGs in oJIA. WGCNA clustered the data into 6 modules in pJIA and 4 modules in oJIA. Notably, the ME5 and ME2 modules exhibited significant associations with pJIA and oJIA, respectively. In both pJIA and oJIA, we identified six hub genes, four of which demonstrated high diagnostic sensitivity and specificity in pJIA, while five showed high diagnostic sensitivity and specificity in oJIA. CIBERSORT analysis suggested the potential involvement of these signature genes in immune cell infiltration.
Conclusion
In this study, we identified JUN, CXCL8, SOCS3, and KRAS as biomarkers for RF-negative pJIA and JUN, CXCL8, SOCS3, PTGS2, and NFKBIA as biomarkers for oJIA. Furthermore, our findings suggest that Tfh cells may play a role in the early onset of both RF-negative pJIA and oJIA.

Globally, increasing morbidity and mortality in farm animals have been linked to climate change. In developing countries which are already overwhelmed by institutional inefficiencies, tackling the impacts of climate change on herd health has become a great concern. This is because, ensuring herd health is quintessential to food security, food safety and sustainable livelihoods under extreme climatic events and environmental uncertainties. Anambra State has been experiencing persistent climate anomalies especially increasing spates of destructive flooding and erosion. These not only impact humans directly but also the health and welfare of farm animals thereby jeopardizing food security. The study assessed measures taken by ruminant farmers in tackling the impact of climate change on herd health in Enugu State Nigeria. One hundred and twenty respondents were sampled. Descriptive (percentage, mean scores), and inferential statistics (regression) were used in data analysis. From the results, all (100%) of the respondents were adapting to the impacts. The effective adaptation practices were provision of shade (x̄ = 3.95; SD = 0.315), increased water intake (x̄ = 3.88; SD = 0.487), providing bedding material during cold (x̄ = 3.87; SD = 0.459) among others. There are challenges encountered in taking the measures including: poor awareness of effective adaptation practices (x̄ = 3.91; SD = 0.343), inadequate extension services (x̄ = 3.89; 0.464), inadequate finance (x̄ = 3.84; SD = 0.485) among others. Agricultural extension should emphasize sustainable ruminant production which ensures that production systems do not further entrench climate change Efforts should be intensified at providing extension agents with relevant information on effective herd health management strategies under the changing climate. Alternative ruminant species could be adopted. Climate change frontliners should prioritize appropriate financing mechanisms for ruminant farmers.

Background
Causative genetic variants cannot yet be found for many disorders with a clear heritable component, including chronic fatigue disorders like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). These conditions may involve genes in difficult-to-align genomic regions that are refractory to short read approaches. Structural variants in these regions can be particularly hard to detect or define with short reads, yet may account for a significant number of cases. Long read sequencing can overcome these difficulties but so far little data is available regarding the specific analytical challenges inherent in such regions, which need to be taken into account to ensure that variants are correctly identified. Research into chronic fatigue disorders faces the additional challenge that the heterogeneous patient population likely encompasses multiple aetiologies with overlapping symptoms, rather than a single disease entity, such that each individual abnormality may lack statistical significance within a larger sample. Better delineation of patient subgroups is needed to target research and treatment.

Methods
We use nanopore sequencing in a case of unexplained severe fatigue to identify and fully characterise a large inversion in a highly homologous region spanning the AKR1C gene locus, which was indicated but could not be resolved by short-read sequencing. We then use GC-MS/MS serum steroid analysis to investigate the functional consequences.

Results
Several commonly used bioinformatics tools are confounded by the homology but a combined approach including visual inspection allows the variant to be accurately resolved. The DNA inversion appears to increase the expression of AKR1C2 while limiting AKR1C1 activity, resulting in a relative increase of inhibitory neurosteroids and impaired progesterone metabolism.

Conclusions
This study provides an example of how long read sequencing can improve diagnostic yield in research and clinical care, and highlights some of the analytical challenges presented by regions containing tandem arrays of genes. It also proposes a novel gene associated with a specific disease aetiology that may be an underlying cause of complex chronic fatigue and possibly other conditions too. It reveals biomarkers that could be assessed in a larger cohort, potentially identifying a subset of patients who might respond to treatments suggested by the aetiology.

Published: September 2023

Background
Real-world studies on semaglutide's effect on weight loss had been largely focused on patient with type 2 diabetes, this study aim to assess the effectiveness of semaglutide in patients with overweight or obesity.
Methods
We conducted a single-center retrospective observational study and collected data on the use of semaglutide for patients with overweight or obesity with a follow-up of up to 9 months.
Results
The study included 611 patients (390 male [63.8%]; mean [SD] age, 41.3 [12.1] years; mean [SD] body weight, 88.9 [16.0]; mean [SD] BMI, 30.9 [4.2]) in the analysis at 3 months, 337 patients at 6months and 105 patients at 9 months. After 3, 6, and 9 months, the mean (SD) weight loss was 4.0 (3.7), 5.1 (4.5), and 6.3 (5.4) kg, respectively, equivalent to 4.5% (4.7%), 5.6% (4.7%), and 7.0% (5.8%), respectively (P < 0.001 for all). Patients with type 2 diabetes had a lower mean (SD) percentage weight loss at 3, 6, and 9 months compared with those without type 2 diabetes: 3.7% (3.1%) vs 5.4% (4.7%) at 3 months (P＜0.05), 5.0% (3.9%) vs 7.1% (4.4%) at 6 months (P＜0.05), and 5.6% (4.7%) vs 8.0% (5.4%) at 9 months (P＜0.05).
Conclusions
The results of this cohort study suggest that semaglutide was associated with weight loss similar to that seen in randomized clinical trials.

Background: Oral nutritional supplement (ONS) formulations may lose their flavor because of the complex nutrients used. Many patients who undergo gastrectomy for gastric cancer cannot ingest sufficient amounts of ONS after surgery. Although the use of simpler nutrients in an ONS may improve the flavor, it is unclear if it can prevent the body weight loss (BWL) of patients with gastric cancer after surgery. This study aimed to evaluate the effects of ONS with carbohydrate and protein on BWL, muscle strength, and health-related quality of life (HRQoL).
Methods: This will be a multicenter, open-label, parallel, randomized controlled trial in patients with gastric cancer who will undergo gastrectomy. A total of 120 patients who will undergo gastrectomy will be randomly assigned to the ONS group or usual care (control) group in a 1:1 ratio. The stratification factors will be the clinical stage (I or ≥II) and surgical procedures (total gastrectomy or other procedure). In the ONS group, the patients will receive 400 kcal (400 ml)/day of ONS from postoperative day 5 to 7, and the intervention will continue postoperatively for 8 weeks. The control group patients will be given a regular diet. The primary outcome will be the percentage of BWL (%BWL) from baseline to 8 weeks postoperatively. The secondary outcomes will be muscle strength (handgrip strength), HRQoL (EORTC QLQ-C30, QLQ-OG25, EQ-5D-5L), nutritional status (hemoglobin, lymphocyte count, albumin), and dietary intake. All analyses will be performed on an intention-to-treat basis.
Discussion: This study will provide evidence showing whether or not ONS with simple nutritional ingredients can improve patient adherence and HRQoL by reducing BWL after gastrectomy. If supported by the study results, nutritional support with simple nutrients will be recommended to patients after gastrectomy for gastric cancer.
