Digital Entrepreneurship and Innovation
Authors: Kasim Mohd Saniazle , Yusof Mohar
Published: November 2021

This chapter is based on a case study that highlights the digital entrepreneurship and innovation of an entrepreneurial venture and team aspiring to address cash flow management issues and pains faced by the micro, small, and medium-sized enterprises (MSMEs) in Malaysia. The entrepreneurial team pioneered the revolutionization of the barter trade concept by developing a digital solution and platform branded as Kongsi (initially named Qu Exchange). Kongsi is a solution using digital trade points which act as a medium of exchange in replace of cash. This solution can solve cash flow problems faced by MSMEs with the creation of a non-cash alternative financing platform, combining and integrating the concept of barter trade and a point-based system. In this case study, the authors examined two critical success factors for digital entrepreneurship and innovation. This case study exemplifies a venture and entrepreneurial team capable of assembling strategic resources to create and sustain competitive advantages to survive and grow in a highly competitive FinTech environment.

Authors: Song Langui , Xie Qingxing , Lv Zhiyue
Published: November 2021

Objective:

Foodborne parasitic diseases, although with a declining overall incidence rate, are still endangering local public safety. This review aims to describe the current situation and epidemiological trends of foodborne parasitic diseases in China in order to explore possible reasons contributors to its high prevalence in some areas, and propose strategies for prevention and control accordingly.

Methods:

A scoping review was conducted by searching PubMed, CNKI, Wanfang, CQVIP, Embase, and the Cochrane Library using search formula “foodborne parasitic diseases (or foodborne parasites)” AND “China”. Studies on foodborne parasitic diseases in China were considered, but only articles in English or Chinese published between January 1980 and June 2020 were retrieved. Included studies were screened according to the eligibility criteria: 1) diseases consistent with the WHO definition of foodborne parasitic diseases; 2) the food carriers were included in the WHO food classification; 3) data related to epidemiology, pathogenicity, and prevention and control; 4) Foodborne parasitic diseases cases or outbreaks in China.

Results:

A total of 111 out of 665 records were included and summarized. The prevalence of clonorchiasis, angiostrongyliasis, echinococcosis, trichinellosis and cysticercosis was still increasing although the infection rate of soil-transmitted nematodes has substantially decreased in recent years. Diverse eating habits, close contact with animals, and urbanization were contributing factors to the increase.

Conclusions:

Foodborne parasitic diseases remain an important public health issue in China with the progress of economic globalization and food diversification. We should manage to raise public awareness about the prevention and control of foodborne parasitic diseases, improve health and safety inspections, as well as public health practice.

Authors: Ismaeil Manal Sayed , Elfeky Hanaa Ali Ahmed , Elnamory Doha Salah
Published: November 2021

Background

Pressure ulcers represent a major health problem, particularly in critically ill patients whose nutritional status is negatively affected by illness. Therefore, careful assessment and monitoring of critically ill patients are important nursing considerations.

Aim

To assess the relationship between nutritional status and occurrence of pressure ulcers among adult critically ill patients.

Research design

A descriptive correlational research design was utilized in this study.

Research questions

1–What is the nutritional status of adult critically ill patients at Cairo University Hospitals? 2–Is there a relationship between nutritional status and pressure-ulcer development among adult critically ill patients at Cairo University Hospitals?

Setting

Different ICUs affiliated to Cairo University Hospitals.

Sample

A purposive sample consisting of 90 patients was included.

Tools of data collection

Demographic and medical data sheet, Braden scale, and Derby nutritional score.

Results

Nearly two-thirds of the studied sample was not at risk of nutritional deficiency in different assessment times in percentages of 58.2, 55.6, 62.2, 66.6, and 61.1%, respectively. As well, nearly half of the patients were not at risk of developing pressure ulcers in different assessment times in percentages of 46.7, 46.7, and 56.3%, respectively. Pressure-ulcer development did not differ significantly in relation to sex and;Deg;BM;Deg;I (χ
2=1.875, P≤0.759, χ
2=5.639, P≤0.688). A negative significant statistical correlation was found between nutritional status and the risk of developing pressure ulcer (r=−0.761, P≤0.000).

Conclusion

Nutritional status was negatively associated with pressure-ulcer development. Age, immobility, and sensory perceptual alteration represented significant determinants of patients’ readiness for developing pressure ulcers.

Recommendations

Regular and careful assessment of critically ill patients’ nutritional status, frequent skin assessment for prevention, early detection of pressure ulcers, availability of written guidelines, and booklets about early detection and management of pressure ulcers.

Published: November 2021

Background:

There is a growing need for information regarding the recent coronavirus disease of 2019 (COVID-19). We present a comprehensive report of COVID-19 patients in Iran.

Materials and Methods:

One hundred hospitalized patients with COVID-19 were studied. Data on potential source of exposure, demographic, clinical, and paraclinical features, therapy outcome, and postdischarge follow-up were analyzed.

Results:

The median age of the patients was 58 years, and the majority of the patients (72.7%) were above 50 years of age. Fever was present in 45.2% of the patients on admission. The most common clinical symptoms were shortness of breath (74%) and cough (68%). Most patients had elevated C-reactive protein (92.3%), elevated erythrocyte sedimentation rate (82.9%), and lymphocytopenia (74.2%) on admission. Lower lobes of the lung were most commonly involved, and ground-glass opacity (81.8%) was the most frequent finding in computed tomography scans. The administration of hydroxychloroquine improved the clinical outcome of the patients. Lopinavir/ritonavir was efficacious at younger ages. Of the 70 discharged patients, 40% had symptom aggravation, 8.6% were readmitted to the hospital, and three patients (4.3%) died.

Conclusion:

This report demonstrates a heterogeneous nature of clinical manifestations in patients affected with COVID19. The most common presenting symptoms are nonspecific, so attention should be made on broader testing, especially in age groups with the greatest risk and younger individuals who can serve as carriers of the disease. Hydroxychloroquine and lopinavir/ritonavir (in younger age group) can be potential treatment options. Finally, patients discharged from the hospital should be followed up because of potential symptom aggravation.

Published: November 2021

In the past 20 years, several viral epidemics such as the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002 and 2003, H1N1 influenza in 2009, and Middle East Respiratory Coronavirus in 2012 have been recorded. The COVID-19 pandemic caused by SARS-CoV-2 has infected millions across the globe and has been a unique public health challenge with its increased rates of contagion and transmission. This outbreak was likely to have started from a zoonotic transmission event associated with a large sea-food market that also traded live wild animals. An exponential increase in the number of nonzoonotic cases in late December 2019, pointed toward the risk of human-to-human transmission. This led to a faster spread of infection and made the outbreak difficult to contain. The situation was unique in the busy Emergency Department (ED) of our institution, where regular emergency care could not be halted but had to be modified to accommodate COVID-19 confirmed and suspect patients. The ED needed to develop standard operating protocols to isolate and manage these patients, without putting other patients and health-care workers at risk of infection. This is a story of evolving practices in the ED of a leading tertiary care center of South India.

Authors: Gajbhiya Akansha M. , Menon Preethi , Chaudhury Suprakash , Saldanha Daniel
Published: November 2021

Background:

Mental disorders occupy a premier position in the matrix of causation of suicide. Suicidal ideation among psychiatric patients is a less explored topic in India.

Aim:

The aim of this study is to study the prevalence and clinical correlates of suicidal ideation in patients attending psychiatry outpatient department (OPD).

Materials and Methods:

This cross-sectional study was conducted in the psychiatry outpatient department of a tertiary care hospital. Beck's suicide intent scale was used to quantify suicidal ideation. Beck's Hopelessness scale and Depression, Anxiety and Stress Scale were used to study levels of hopelessness, depression, anxiety, and stress in patients. Groups with and without suicidal ideations were compared on different variables.

Results:

Suicidal ideation was present in 36% of psychiatry OPD patients. Out of these 13% patients had previous suicidal attempts. Most of them attempted suicide once. Majority had either fleeting suicidal ideas or passive death wish, with poisoning noted as the most common method of attempted suicide. Suicidal ideation had a statistically significant association with levels of depression, anxiety, and stress. Highest stress levels were found in anxiety disorders. Suicidal ideation was commonly observed in patients with depression and other mood disorders and those with previous attempts. More than half of the patients with suicidal ideation never sought help.

Conclusion:

Increasing levels of depression, anxiety, stress, and hopelessness were associated with increased suicidal ideation. Substance use, history of psychiatric illness, triggering stressor, and low perceived social support were also associated with suicidal ideation in psychiatric patients.

Published: November 2021

Background Statement:

Inadequate retinopathy of prematurity (ROP) screening coverage portends a high risk for increasing the cases of ROP blindness. This study aims to report the clinical profile of pre-term babies who developed ROP blindness, highlight the usefulness in determining screening criteria and the role of private hospitals in ROP blindness prevention.

Case Series Report:

Online Google form and telephone survey was conducted from May to December 2020 among paediatric ophthalmologists who provided the clinical details of ROP blind children seen between 2016 and 2020. The main outcome measured included type of the hospital of birth, gestational age, birth weight, ROP Screening and treatment, and blinding ROP Stage among children born premature. The SPSS-IBM version 26 was used for the analysis. Eighteen children blind from ROP with an equal male-to-female ratio were reported. Mean gestational age was 28.4 ± 2.2 weeks (range 26 - 34 weeks, median was 28.0 weeks). Mean birth weight was 1173.7 ± 317.9 grams (range 776 - 2100 grams, median 1125 grams). Six (33.3%) babies were born in private hospitals between 28 and 32 weeks. Sixteen (88.9%) children never had ROP screening. Fifteen (83.3%) were blind in both eyes. Six (33.3%) had Stage IVb and 12 (66.7%) Stage V.

Conclusion:

About 90% of the babies who became blind did not undergo ROP screening. It is crucial that all babies born at 34 weeks or earlier and have birth weight of < 1500 grams in public/private hospitals be screened for ROP to prevent this avoidable blindness in Nigeria.
Metabolic rescue of cone photoreceptors in retinitis pigmentosa
Authors: Kaplan Henry J. , Wang Wei , Piri Niloofar , Dean Douglas C.
Published: November 2021

Retinitis pigmentosa (RP) encompasses a group of inherited retinal dystrophies characterized by the primary degeneration of rod and cone photoreceptors. It is a leading cause of visual disability, with an incidence of ~1 in 7000 persons. Although most RP is nonsyndromic, 20%–30% of patients with RP also have an associated nonocular condition. The gene mutations responsible for RP occur overwhelmingly in rod photoreceptors. Visual loss frequently begins with night blindness in adolescence, followed by concentric visual field loss, reflecting the principal dysfunction of rod photoreceptors. Although the visual disability from rod dysfunction is significant, it is the subsequent loss of central vision later in life due to cone degeneration that is catastrophic. Until recently, the reason for cone dysfunction in RP was unknown. However, it is now recognized that cones degenerate, losing outer segment (OS) synthesis and inner segment (IS) disassembly because of glucose starvation following rod demise. Rod OS phagocytosis by the apical microvilli of retinal pigment epithelium is necessary to transport glucose from the choriocapillaris to the subretinal space. Although cones lose OS with the onset of rod degeneration in RP, regardless of the gene mutation in rods, cone nuclei remain viable for years (i.e. enter cone dormancy) so that therapies aimed at reversing glucose starvation can prevent and/or recover cone function and central vision.

Published: November 2021

Scorpion stings are common emergencies in the tropics. Species-specific antivenom therapies are available. However, fatalities resulting from scorpion stings remain a public health concern in many settings. Children residing in rural towns and peri-urban areas represent the most vulnerable populations. Delays in the diagnosis of scorpion stings often occur as a result of the non-specific clinical presentations, which then lead to life-threatening complications. We report a 2-year-old Venezuelan boy presenting with acute pancreatitis and pulmonary edema without an identifiable cause 48 hours after his initial symptoms. We administered antivenom therapy when an undetected scorpion sting was suspected. Despite some initial clinical improvement with respect to his acute pancreatitis, pulmonary edema, and coagulation abnormalities, our patient experienced an ischemic stroke. Fortunately, our patient did demonstrate some neurological improvement. Although acute pancreatitis and pulmonary edema are known end-organ damage manifestations of the sting of Tityus in the Americas, our particular case illustrates the risk of ischemic stroke.

Published: November 2021

AIMS OF THE STUDY: Thyroid cancer incidence rates have been increasing globally over past decades. However, no study examining those trends in the canton of Zurich, Switzerland exists. In this study, we describe the incidence and mortality trends of thyroid cancer in the canton of Zurich during a 37-year period (1980–2016) including factors such as sex, histological subtypes and age at diagnosis.
METHODS: We analysed population-based cancer registry data from 1980-2016 for the canton of Zurich, Switzerland. We estimated the age-standardised incidence and mortality rates using the European standard population. Joinpoint regression was used to detect average annual percentage changes (AAPCs) and their corresponding 95% confidence intervals (CIs).
RESULTS: We included 2972 primary cases of thyroid cancer (72.3% in women). The papillary cases accounted for the majority of incident cases (65.8%). In 2016, women had a higher age-standardised incidence rate than men for both papillary (10.4 and 3.3, respectively, per 100,000) and non-papillary (1.6 and 0.7, respectively, per 100,000) thyroid cancer. In both men and women, the incidence rates of thyroid cancer increased significantly over the study period with AAPCs of 1.4% (95% CI 0.6–2.2%) and 2.6% (95% CI 2–3.1%), respectively. These increasing incidence trends are mainly driven by papillary thyroid cancer with AAPCs of 3.4% in men (95% CI 2.3% to 4.4%) and 4.3% in women (95% CI 3.7% to 5%). Mortality rates significantly decreased in both sexes (men AAPC –3.6%, 95% CI –4.7% to –2.4%; women AAPC –3.7%, 95% CI –4.8% to –2.6%).
CONCLUSIONS: Our results show significantly increasing age-standardised incidence rates of thyroid cancer over time in both sexes, mainly due to papillary thyroid cancer, the most frequent histological subtype, and the only subtype for which a significant increase was observed. It is possible that many indolent thyroid cancers, and more specifically papillary microcarcinomas, are increasingly diagnosed, which may not lead to symptoms if undetected. Therefore, targeted diagnostic strategies are necessary to avoid overdiagnosis of thyroid cancer. Nevertheless, we cannot completely exclude a partly true increase.

Authors: Aggarwal Preeti , Sardana H. K. , Vig Renu
Published: November 2021

In lung cancer computer-aided diagnosis (CAD) systems, having an accurate ground truth is critical and time consuming. Due to lack of ground truth and semantic information, lung CAD systems are not progressing in the manner these are supposed to. In this study, we have explored Lung Image Database Consortium (LIDC) database containing annotated pulmonary computed tomography (CT) scans, and we have used semantic and content-based image retrieval (CBIR) approach to exploit the limited amount of diagnostically labeled data in order to annotate unlabeled images with diagnoses. We evaluated the method by various combinations of lung nodule sets as queries and retrieves similar nodules from the diagnostically labeled dataset. In calculating the precision of this system Diagnosed dataset and computer-predicted malignancy data are used as ground truth for the undiagnosed query nodules. Our results indicate that CBIR expansion is an effective method for labeling undiagnosed images in order to improve the performance of CAD systems while tested on PGIMER data. Also a little knowledge of biopsy confirmed cases can also assist the physician’s as second opinion to mark the undiagnosed cases and avoid unnecessary biopsies

Published: November 2021

In this work, a study investigation was carried out using n-grams to classify sentiments with different machine learning and deep learning methods. We used this approach, which combines existing techniques, with the problem of predicting sequence tags to understand the advantages and problems confronted with using unigrams, bigrams and trigrams to analyse economic texts. Our study aims to fill the gap by evaluating the performance of these n-grams features on different texts in the economic domain using nine sentiment analysis techniques and found more insights. We show that by comparing the performance of these features on different datasets and using multiple learning techniques, we extracted useful intelligence. The evaluation involves assessing the precision, recall, f1-score and accuracy of the function output of the several machine learning algorithms proposed. The methods were tested using Amazon, IMDB, Reuters, and Yelp economic review datasets and our comprehensive experiment shows the effectiveness of n-grams in the analysis of sentiments.

Authors: Amos O. , Odetoye T. E , Ogunniyi D. S.
Published: November 2021

Zinc metal soaps are of great importance in the manufacture of personal care products and other industrial applications. Variations in the soaps and their properties are usually due to the type of oil used in the synthesis. Shea butter (Vitellaria paradoxa), being a valuable industrial raw material, was investigated for the synthesis of zinc metal soap. Locally obtained shea butter was characterized, refined and used to synthesize metal soap of zinc which was characterized. The zinc soap produced exhibited an off-white appearance, pH of 7.8, non-foaming, and no free alkalinity present. The functional groups in the soap were confirmed by FTIR.

Tin mining tailings are unprocessed waste materials that overlie an ore which are displaced during mining activities. This research work is aimed at characterizing and evaluating the human health risk of heavy metals in tin mine tailings in Zabot (S3) and Tafan (S4) districts in Barkin Ladi Local Government Area of Plateau State, Nigeria. The samples were characterized using EDX-XRF and SEM. The concentrations of seven heavy metals (Pb, Cr, As, Ni, Cd, Cu and Zn) were determined in S3 and S4. The results showed that Cr, Ni, Cd, Cu and Zn were within the USEPA permissible limits, except for Pb and As with range of (270-300) mg/kg and (40-70) mg/kg respectively for both mining and control sites of S3 and S4. The SEM results revealed small particles size with fine porous structure, and rough areas with varying sizes and pores distributed over the surface for S3 and S4 respectively. Results of the risk assessment showed that the hazard quotient HQ and HI values were greater than 1 indicating high risk. The Carcinogenic and non-carcinogenic risks associated with Pb, Zn, Cd, Cr, Ni and As were evaluated for S3 and S4 for the three exposure pathway and it was found that the mining sites pose more risk than the control and the children were more exposed than the adults. The carcinogenicity of these samples were due to the high hazard quotient for ingestion and dermal exposure pathway. The R total results for As, Cr, Pb and Ni for mining site S3 were found to be (1.39 × 102 , 2.02 × 10-7 , 3.30 × 103 and 8.17 × 10-8 ), and control site (3.42 × 103 , 2.64 × 10-5 , 38.30 × 101 , 6.90 × 10-8 ) for As, Cr, Pb and Ni respectively. From the R total results As and Pb were more than the acceptable threshold, while Cr and Ni were below the threshold of 1 × 10-4 . For the mining site S4, the R total were found to be (5.70 × 102 , 1.82 × 10-7 , 3.63 × 104 and 9.64 × 10-9 ),and the control (1.16 × 103 , 1.71 × 10-7 , 31.1 × 102 and 1.51 × 10-8 ) for As, Cr, Pb and Ni respectively. From the results of the mining and control sites, As and Pb R total were higher than the acceptable threshold, while Cr and Ni were below the threshold of 1 × 10-4 .

Published: November 2021

This research isolates, characterizes, and studies the computational and frequency calculations of emodin, extracted from the leaf extract of Pteridium acquilinum leaves using methanol. Vacuum liquid and tin layer Chromatography was used for the purification of the molecule. The (VLC purified), fraction was analyzed by Nuclear magnetic resonance (NMR) and the chemical structure of the compound isolated (anthraquinone), was confirmed by 1H & 13C-NMR analyses  as emodin (C15H10O5). Computational and frequency studies have been done on the isolated molecule. Optimized geometry, IR frequencies, Bond distances (R) and angles (A), Dipole moments and other parameters have been computationally determined for the isolated molecule from quantum chemical calculations using the GAUSSIAN 09 retinue programs. Experimentally determined and computationally measured IR frequencies agree perfectly with each other. Computational studies can be used to predict unobserved chemical phenomena like design of new drugs and materials such as the positions of constituent atoms in relationship to their relative and absolute energies, electronic charge densities, dipoles, higher multiple moments, vibrational frequencies, relativity or other spectroscopic quantities and cross sections for collision with other molecules. This is the first time this anthraquinone, [emodin], with most of the parameters examined is reported from P. aquilinum.

Published: November 2021

Lead (Pb) free (non-toxic) perovskite solar cells materials have attracted great interest in the commercialization of the photovoltaic devices. In this work, density functional theory (DFT) and linear response time-dependent within density functional theory (TDDFT) are used to simulate and investigate the effect of gold (Au) dopedPb-free double halide perovskite A2BB?X6(A = Cs; B = In, Au; B? = Sb; X = Cl) on the structural, electronic, and optical properties for perovskite solar cell application. On the structural properties, bond length and bulk modulus calculations show that the doped compound is more likely to resist deformation than the undoped compound. The calculated band structure for both materials (doped and undoped) reveals the presence of the Valence Band Maximum (VBM) and the Conduction Band Minimum (CBM) at around the same symmetry point which indicates a direct band gap nature (at ???? point). The band gap value for the initial compound (= 0.99 eV) agrees with published theoretical values. For the gold doped compound, the value of the band gap increased to a value of 1.25eV. The result of the optical properties shows that the Au-doped material has higher absorption coefficient, lower reflectivity and higher optical conductivity when compared with the initial, as such demonstrates better properties as a candidate for solar cell applications and in other optoelectronic devices.
ДРУШТВЕНИ КАПИТАЛ У ФУНКЦИЈИ УНАПРЕЂЕЊА РЕГИОНАЛНОГ РАЗВОЈА

Published: November 2021

Regional development strategies should be based on the sound assessment of regional resources, capabilities, competences and core competences, as well as on dynamic capabilities aiming to develop the resource configurations in order to form their regional competitive advantage. Therefore, new regionalism is basically a bottom-up process, because the prerequisites for its successful implementation are the leadership and vision of local actors and administrations, civic participation, the growth of social capital and administrative decentralization and devolution of power. In that sense, the paper deals with important issues regarding the intangible determinants of regional economic development. The research method that will be dominantly used in this paper is the case-study method which aims to fully and thoroughly reconstruct the presence and role of social capital (primarily its structural dimension - social network platforms) in the regional development of world-famous and successful regions such as Silicon Valley, Baden-Wurttemberg and Emilia-Romagna. The overall conclusion of the paper is that regional growth is a function of the social capital stocks of respective regions to a significant extent. Social capital is positively linked to regional development and economic prosperity by reducing transaction costs, articulating collective actions, encouraging innovation and technology dissemination, discouraging opportunism and increasing monetary and non-monetary cost of fraud.
AN INTRODUCTION TO THE MODERNIST NOVEL
Authors: Tučev Nataša
Published: November 2021

This book is intended as an introduction to the modernist novel, primarily for the students and scholars of the English language and literature. Four major novelists – Joseph Conrad, D. H. Lawrence, James Joyce and Virginia Woolf – have been chosen to exemplify the stylistic features, aesthetic preoccupations and thematic concerns of the works of fiction written in English in the early decades of the twentieth century. The methodological principle used in this study is multilevel. First, these four authors are analysed by referring to their essays, philosophical treatises, prefaces to their novels and other nonfictional works where they define their poetics and their artistic goals in their own terms. After this, since form is such a major concern of the modernist novel, formal innovations and narrative strategies of each of these authors are discussed at some length. Finally, a single novel is chosen to represent each author, and it is analysed in detail. Heart of Darkness, A Portrait of the Artist as a Young Man and Mrs Dalloway are widely recognized within the oeuvre of these novelists as some of their greatest artistic achievements. Lawrence’s novella St Mawr is a lesser-known work; however, I would argue that F. R. Leavis’s praise of this short piece as “an astonishing work of genius” still stands. The same as with the other three novels, its inclusion in the study is justified by the valuable insights it provides about the characteristics of modernist fiction and modernist art in general.

Nghiên cứu này sử dụng ảnh vệ tỉnh Landsat LC8 của các năm 2013, 2014, và 2019 để giải đoán phân loại lớp phủ cây cao su ở huyện Bố Trạch, tỉnh Quảng Bình và đánh giá biến động diện tích cao su sau ảnh hưởng của bão số 10 (tên là Wutip) năm 2013. Kết quả giải đoán còn sử dụng để đánh giá thiệt hại diện tích trồng cây cao su do ảnh hưởng của bão số 10 năm 2013 và biến động diện tích trồng cây cao su giai đoạn 2013-2019. Các số liệu điều tra thực địa, phỏng vấn cán bộ, số liệu báo cáo thứ cấp, tài liệu phục vụ các hội thảo về phát triển cây cao su ở Quảng Bình đã được thu thập để hỗ trợ cho công việc phân tích, giải đoán ảnh vệ tinh. Nghiên cứu này kết hợp phương pháp giải đoán ảnh theo định hướng đối tượng kết hợp với thuật toán Maximum Likelihood. Kết quả giải đoán đã được đánh giá, độ chính xác giải đoán tổng thể biến động từ 82-88% và hệ số Kappa biến động từ 0,8-0,87 trong các năm nghiên cứu. Qua thống kê kết quả giải đoán ảnh viễn thám Landsat LC8, diện tích trồng cây cao su tại huyện Bố Trạch, tỉnh Quảng Bình bị thiệt hại đáng kể do ảnh hưởng của bão số 10 năm 2013, hơn 1.500 ha bị thiệt hại. Tuy nhiên, mỗi năm diện tích cây sao su được khôi phục lại và trồng mới tại huyện Bố Trạch, do đó sau bão số 10 năm 2013, diện tích cây cao su tăng lên đáng kể từ năm 2014-2019, hơn 2.500 ha.

ABSTRACT

This study used Landsat LC8 satellite images of 2013, 2014, and 2019 to interpret the classification of rubber tree landcover in Bo Trach district, Quang Binh province and evaluate changes in rubber area after the impact of storms number 10 (named Wutip) in 2013. The results of interpretation were also used to assess the damage of rubber plantations due to the impact of typhoon number 10 in 2013 and changes in rubber plantation area in the period of 2013- 2019. Data from field surveys, interviews with local staff, secondary report data, and documents of conference on rubber tree development in Quang Binh was collected to support analysis and interpretation. This study combined the object-oriented image analysis method combined with the Maximum Likelihood algorithm. The interpretation results were evaluated, the overall interpretation overall accuracy varied from 82-88% and the Kappa coefficient varied from 0.8-0.87 in the studied years. Through the statistical interpretation results of the Landsat LC8 detective, the rubber plantation area in Bo Trach district, Quang Binh province was significantly damaged due to the impact of typhoon number 10 in 2013, over 1500 hectares were damaged. However, each year, the area of ​​​​the rubber tree is restored and newly replanted in Bo Trach district, so after the typhoon number 10 in 2013, the area of ​​rubber trees increased significantly from 2014-2019, over 2,500 ha.

The objective of this study is to be able to find ways or the best strategies in teaching that will motivate students to exert effort in their studies, considering the present conditions in this pandemic period. A quantitative method was used to define the study's objective, where two sections of Psychology students who took up Science 101 and Science 104 were chosen as respondents to answer the survey questionnaire through google forms. The purposive sampling technique was also employed since these students can appropriately answer the queries sent to them. The Likert scale method was used to measure the students' level of agreement, with the 5-point range, where the results were collated and analyzed.  The research result finds several strategic activities such as report enhancement, online debates, virtual experiments, discussion and updating of recent findings, and the creation of infomercials that truly captured their interest and attention. This study made use of several references and tables in order to support the results obtained. The researcher recommends that there should be effective and efficient motivational activities to sustain student engagement. The researchers, who are also educators, have agreed to continuously upgrade the newfound motivational activities to encourage more students to study well even in an online setting, thus giving more opportunities for better achievement in education.
FORMATION OF ZOOPLANKTON IN THE BOGUCHANY RESERVOIR DURING ITS FILLING
Authors: Sheveleva N.
Published: November 2021

For the first time, we present the materials of the spatial distribution of qualitative and quantitative indicators of zooplankton in the first year of top water level (TWL) in the Boguchany Reservoir. We indicate the dynamics of the formation of the zooplankton community in the Upper section of the reservoir during its filling (from 2013 to 2015). The Irkutsk, Bratsk, and Ust-Ilimsk reservoirs influence the composition and structure of zooplankton in the Boguchany Reservoir that closes the cascade of the Angara HPPs, and there is a great similarity of the crustacean and rotifer fauna with the upstream artificial reservoirs. During the study period (from 2013 to 2017), the plankton fauna included 84 species from 49 genera and 23 families. The horizontal distribution of quantitative indicators throughout the water area of the reservoir had a mosaic pattern. The relative and absolute proportion of rotifers in the composition of zooplankton decreased from the Upper section to the Lower one, and the dominance of crustaceans was opposite. Due to this, the maximum number (129±97.8 thou ind./m3) of zooplankton was recorded in the Upper section, and the biomass (2080±676 mg/m3) – in the Lower section. The obtained unique data on the composition, structure and quantitative development of zooplankton in the Boguchany Reservoir during its formation and filling are important for further monitoring of its state, including the assessment of the feeding of planktonophagous fish and juvenilefish.

Carbuncle is a painful subcutaneous mass of infected hair follicles with a purulent discharge. It has predisposition in conditions like diabetes, immune-compromised states, chronic skin diseases etc. The authors present a case of a 67 year old diabetic male with a giant carbuncle on his back. Due to its large size, systemic co-morbidity and increased risk of complications in surgical treatment, a multi-disciplinary team approach was employed. Both general and plastic surgery were involved, who performed excision and soft tissue coverage respectively. Aim of the surgical intervention methods, like wide excision and debridement, application of vacuum assisted wound closure (VAC) and skin grafting was to minimize the healing time and risk of development of post-operative infection. The patient was surgically managed and sent home in a good condition.

The Second Interrupted Revolution. Juan Guzmán and the case of foot-and-mouth disease. A German photographer in the middle of the war in the Mexican countryside.

Through the photographs of foot-and-mouth disease in Mexico, taken by the photojournalist Hans Gütman/ Juan Guzmán in 1947, this terrible pandemic and the inhumane handling it was given are analyzed. The study of this series of images, from the perspective of visual anthropology, reveals interesting contradictions in the development version of the Mexican government, which for the same reason published them in the magazine Mañana up to 5 years after the photographs were taken. Said “official” version defined foot-and-mouth disease as “an evil ghost” that took over the national cattle, “reason why it had to be exterminated” in order to lead Mexico “into economic and social progress”, a version that is tendentious and contrary to reality of the process revealed by these images.
