Comparison of moss bag and native moss technique in monitoring airborne particulate and toxic elements
Authors: Nguyen Son An , Thi Minh Sang Nguyen , Hong Khiem Le 
Published: May 2021

Introduction: In Vietnam, the government has invested in monitoring stations in a few big cities like Hanoi and Ho Chi Minh City, which have transportation centers and industrial zones, to assess and predict levels of air pollution. However, the main disadvantage of installing monitoring stations is the cost of investment for operations, maintenance, and equipment. It is also time-consuming to collect and analyze the results. Therefore, it is generally not suitable for the country as a whole.
Methods: Using mosses to monitor air quality brings qualitative and quantitative data with simple, environmentally-friendly economic methods. Mosses have particular biological characteristics that make them very suitable adsorbents for a wide variety of chemical elements. When used as transplants like moss bags, allow them to monitor a highly dense sampling network of any site easily. Mosses are bioindicators, plants with artificial roots.
Results: In this study, moss bag and native moss were the two methods used to evaluate the accumulation of trace elements in air through Barbula Indica. Observations showed that both methods could detect the same elements: Al, Si, P, S, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Y, Sb, Ba, Pb, and U. However, the accumulation of the elements in native moss is higher than in moss bag. The main reason is that the absorption efficiency of native moss in air-deposited elements is higher than in moss bags.
Conclusion: Moss bags have been used most extensively and successfully in urban areas, where vegetation samples are either unobtainable or are poorly located to the source. These areas can lack moss, or the native moss simply does not grow during the dry season.

Napjainkban a repülőgép-hajtóművek szerkezetének, elemeinek tervezésében, gyártásában a mérnökök számára elengedhetetlen egy-egy olyan számítógépes szoftver, amely a valósághoz hűen képes a közegek áramlásának fizikai-matematikai modellezésére vagy éppen a megmunkáló eszközök munkájának optimalizálására. Esetünkben a szimulációval könnyedén helyettesíthetők a költséges teszttermékek, valamint ezzel párhuzamosan csökkenthető a kísérletek során keletkező környezetszennyező anyagok légtérbe jutása, valamint a kivitelezésre vagy az esetleges fejlesztésre szánt idő is minimalizálható. Erre a feladatra leggyakrabban az ANSYS számítógépes szoftvert alkalmazzák. Ez egy olyan numerikus áramlástani szoftver, amely térben és időben folytonos műveleteket diszkretizál, így a hajtóművek égéstereinek vizsgálatára kiválóan alkalmazható. Cikkünkben az említett szoftvernek a szerzők által kitűzött feladatra való alkalmasságának elemzését, majd az alkalmazás eredményét kívánjuk bemutatni. Az elemzés során az ANSYS CFX szoftver segítségével hajtottuk végre a különféle hajtóművek áramlástani szimulációját. Célunk, hogy a publikáció végére az olvasó számára átfogó képet mutassunk az áramlástechnikai gépekben lejátszódó folyamatokról, ezen belül az égéstér szimulációjáról.
Bouncing forward in challenging times

The COVID-19 pandemic is a disruption which has posed challenges to food sector organizations. Yet it may also provide an opportunity for growth of and change in these organizations. Our aims were to describe the surge in demand and innovations introduced by a rural food distribution cooperative and to critically assess responses in light of organizational resilience literature. We chose an organizational case study approach with mixed methods. Data sources included: existing reports, newsletters, policies and quantitative indicators; and new stakeholder interviews (n=20). We describe: the development and nature of the cooperative; its consolidation and anticipatory planning; the March 2020 surge in orders (133/week in February to 205/wk in March); the prioritization of health and safety in modifying product receiving and delivery methods; the warehouse reorganization and product aggregation doubling to twice per week; the strains on employees and human resource challenges; yet the growing organizational resilience. We reflect on the small role of the cooperative in the inequitable agri-food system of the counties it serves, yet the strong role it plays with other food security oriented organizations in keep with its values. Further work, both research and practice development, can continue to explore the ways in which complex multi-stakeholder, not-for-profit, socially and environmentally principle food organizations can better navigate disruptions in the coming years, particularly in rural areas.
Apakah UMR Mempengaruhi Penyerapan Tenaga Kerja : Pendekatan Model Demometrik
Authors: Hakim Arief Rahman , Pakpahan Aston 
Published: May 2021

Salah satu tujuan dalam pembangunan daerah dan pembangunan nasional adalah penyerapan tenaga kerja dan penurunan pengangguran. Studi tentang penyerapan tenaga kerja selama ini hanya dilakukan dengan pendekatan ekonomi (economic base) yang melihat aspek tenaga kerja dari sisi permintaan saja. Kondisi ini kurang lengkap karena mengabaikan sisi penawaran. Perlu dilakukan studi yang lebih komprehensif dari aspek ekonomi sebagai sisi permintaan dan aspek demografi sebagai sisi penawaran. Pendekatan ini dikenal sebagai model Demometrik.
Penelitian bertujuan mengkaji faktor-faktor yang mempengaruhi penyerapan tenaga kerja dengan model demometrik. Aspek ekonomi yang dikaji adalah investasi dan tingkat upah, sedangkan aspek demografi yang diteliti adalah jumlah penduduk. Data yang digunakan dalam penelitian ini berasal dari seluruh 14 kabupaten/kota di Provinsi Kalimantan Tengah pada periode 2010 – 2019 (9 tahun, dikurangi data tahun 2016). Analisis data dilakukan dengan regresi linear berganda data panel sederhana.
Hasil penelitian menunjukkan bahwa variabel investasi dan jumlah penduduk berpengaruh posituf dan signifikan terhadap penyerapan tenaga kerja sedangkan upah minimum regional tidak berpengaruh terhadap penyerapan tenaga kerja.

Indexing the humanities knowledge in the Library Bibliographic Classification
Authors: Volkova N. A. , Khodanovich M. A. 
Published: May 2021

Changing scientific knowledge entails the exclusion of some areas of research and inclusion of others into the main line of development of science, with the new publications revising well-established concepts and offering the new ones. Any rational reconstruction of the history of science has to identify the line of development that has resulted in the modern knowledge.The Soviet Library and Bibliographic Classification developed in the mid-20th century responded to the challenges of the epoch. The paradigm shift of the 1990s in this country resulted in the conceptual revision of scientific values and the emergence of new academic disciplines. That period gave rise to applied studies with their specific goals and values, standards and norms.In the recent period, the humanities studies proliferate to construct generalized interdisciplinary theory. The vast number of publications in the humanities knowledge suggests that the appropriate place for these studies within the structure of the national Library Bibliographic Classification has to be found.
Redes sociales, autoeficacia academica y bienestar en adolescentes de la zona Maya de Yucatan

Published: May 2021

The relationship between the use of social networks and the students´ academic self-efficacy and perception of wellbeing is explorer in adolescents from the Mayan zone of the Yucatán, Mexico. Three instruments exploring these variables were administered to 1013 students form 7th and 9th grades. Access to social network in these adolescents seem to be like those in the cities, suggesting some equity in these two contexts. Results evidences no significant relationships between the variables, expect from the logical significant relationship between high self-efficacy and better school grades. Women scored higher in every dimension of wellbeing and reported higher expectations for college entrance than men. Nine graders scored lower both in self efficacy and perceptions of wellbeing, maybe because to developmental issues associated to adolescence. This higher perception of wellbeing in rural women deserves further considerations in view of commonly held beliefs that women in rural context are in vulnerability and disadvantage in comparison to men.
Silk Vista Baby Is a Safe and Technically Feasible Flow Diverting Stent for Distal Aneurysm Treatment

Published: May 2021

Background and Purpose: Flow diverting stents are designed to divert blood flow from the aneurysm sac, allowing for eventual occlusion following endovascular therapy. This case series reports clinical experience using the Silk Vista Baby (SVB, Balt Extrusion, Montmorency, France), a flow diverter (FD) designed to treat intracranial aneurysms in small, distal vessels.Methods: All patients who underwent treatment with SVB at the University Hospital “Santa Maria della Misericordia” of Udine between July 2018 and September 2020 were retrospectively identified. Baseline patient and aneurysm characteristics, intraprocedural technical outcomes, periprocedural complications, modified Rankin Scale (mRS) at discharge, magnetic resonance imaging (MRI) results at 3-month follow-up, and angiographic results at 6-month follow-up were collected.Results: A total of 18 patients (55.6% [10/18] male; mean age 62.6 years, range: 42–77 years) were retrospectively identified, receiving treatment for 22 aneurysms. Most patients were symptomatic (14/18, 77.8%) and approximately half had subarachnoid hemorrhage (10/18, 55.6%). Sufficient aneurysm coverage was achieved in 88.9% (16/18) of patients with a single device. Mortality did not occur (0/18, 0%); adverse device-related events included side branch occlusion (1/18, 5.6%) and in-stent thrombosis (1/18, 5.6%). At discharge, 77.8% (14/18) had an mRS of 0. In most cases, patients showed complete occlusion (10/15, 66.7%) or a small aneurysmal remnant (3/15, 20.0%) upon MRI; upon angiography, most showed complete occlusion (10/13, 76.9%) or only a small aneurysmal remnant (2/13, 15.4%).Conclusion: This case series showed that the SVB FD is safe and feasible to use in patients with aneurysms in small, distal vessels. Additional randomized, prospective studies with larger cohorts are needed for the SVB.

PurposeOur previous study showed that hepatic arterial infusion chemotherapy (HAIC) using oxaliplatin, fluorouracil, and leucovorin (FOLFOX) plus sorafenib provided a significant survival benefit over sorafenib for advanced hepatocellular carcinoma. However, it is unclear whether the survival benefit should be attributed to the synergism between HAIC and sorafenib or just HAIC alone. We aim to compare HAIC using FOLFOX plus sorafenib with HAIC alone in patients with advanced hepatocellular carcinoma.Materials and MethodsThis was a retrospective study including 225 eligible patients treated with HAIC using FOLFOX (HAIC alone group, n=126, oxaliplatin 85 mg/m², leucovorin 400 mg/m², fluorouracil bolus 400 mg/m² and 2400 mg/m² for 46 hours, every 3 weeks) alone or HAIC plus sorafenib (soraHAIC group, n=99, sorafenib 400 mg twice daily). Survival curves were calculated by the Kaplan-Meier method, and propensity-score matching was used to reduce bias.ResultsThe soraHAIC group showed a longer overall survival (12.9 [95% CI, 10.4-15.4] vs. 10.5 [95% CI, 9.5-11.5] months, HR=0.71 [95% CI, 0.53-0.96]; P=0.025), a better progression free survival (7.0 [95% CI, 5.3-8.8] vs. 5.3 [95% CI, 3.5-7.1] months, HR=0.76 [95% CI, 0.58-0.99]; P=0.046), and a higher disease control rate (RECIST 1.1: 74.8% vs. 61.1%, P=0.030) than the HAIC alone group. In multivariate analysis, soraHAIC was an independent favor factor for survival. In terms of the grade 3/4 adverse event, hand–foot skin reaction was more frequent in the soraHAIC group than the HAIC alone group. In the propensity-score matched cohorts (93 pairs), the overall survival, the progression free survival and disease control rates in the soraHAIC group were also better than those in the HAIC group (P&lt;0.05).ConclusionHAIC plus sorafenib may improve overall survival and progression free survival compared with HAIC alone as initial treatment for advanced hepatocellular carcinoma.

Background: During the COVID-19 pandemic, many patients admitted to hospital for treatment have recovered and been discharged; however, in some instances, these same patients are re-admitted due to a second fever or a positive COVID-19 PCR test result. To ascertain whether it is necessary to treat these patients in hospitals, especially in asymptomatic cases, we summarize and analyze the clinical and treatment characteristics of patients re-admitted to hospital with a second COVID-19 infection.Methods: Of the 141 COVID-19 cases admitted to the Wenzhou Central Hospital between January 17, 2020, to March 5, 2020, which were followed until March 30, 2020, 12 patients were re-admitted with a second COVID-19 infection. Data was collected and analyzed from their clinical records, lab indexes, commuted tomography (CT), and treatment strategies.Results: Most of the 141 patients had positive outcomes from treatment, with only 12 (8.5%) being re-admitted. In this sub-group: one (8.3%) had a fever, a high white blood cell count (WBC), and progressive CT changes; and one (8.3%) had increased transaminase. The PCR tests of these two patients returned negative results. Another 10 patients were admitted due to a positive PCR test result, seven of which were clinically asymptomatic. Compared to the CT imaging following their initial discharge, the CT imaging of all patients was significantly improved, and none required additional oxygen or mechanical ventilation during their second course of treatment.Conclusions: The prognoses of the re-admitted patients were good with no serious cases. We conclude that home treatment with concentrated medical observation is a safe and feasible course of treatment if the patient returns a positive PCR test result but does not display serious clinical symptoms. During medical observation, patients with underlying conditions should remain a primary focus, but most do not need to be re-admitted to the hospital.
USO DE ANTIMICROBIANOS NA SUINOCULTURA: INDICAÇÕES E RESTRIÇÕES
Authors: Stella Ariel Eurides , Oliveira Angélica Franco de , Moreira Cecília Nunes , Viali Kevin Guilherme 
Published: May 2021

Os antimicrobianos são utilizados na produção animal desde a década de 60, na suinocultura de quatro maneiras diferentes – como promotores de crescimento, profiláticos, metafiláticos e terapêuticos. O uso indiscriminado, aliado a subdosagens, classes erradas e destino inadequado de resíduos são um problema não só para produtores e trabalhadores da área, mas para a saúde pública e ambiental. Acredita-se que alternativas como a vigilância e o diagnóstico de uso na produção animal, bem como, o levantamento e a promoção de um banco de dados para caracterizar, determinar ou restringir seu uso, podem reduzir a incidência de genes de resistência. Algumas alternativas para a diminuição do seu uso estão ligadas a qualidade sanitária do rebanho, englobando aspectos como biosseguridade, utilização de um programa vacinal completo e promoção do bem-estar dos animais. Muitos países e organizações também estão promovendo políticas de controle do uso dessas substâncias na produção animal. A utilização de antimicrobianos na suinocultura tende a ser reduzido através de campanhas de conscientização e treinamento dos produtores, alertando para o uso racional dessas drogas afim de combater a resistência bacteriana e aproveitar sua eficiência de maneira segura. Esta revisão busca elucidar alguns pontos do uso de antimicrobianos na suinocultura brasileira, bem como seus possíveis impactos, restrições e alternativas.
Dobro wspólne okiem socjologa — kilka uwag porządkujących
Authors: Mika Bartosz 
Published: May 2021

This text can be defined as an attempt to look at the question of the common good through sociological glasses. The author suggests that many of the issues subsumed under the term “the common good” have already been elucidated and described in detail on the basis of classical and contemporary sociology. If it is assumed that the common good can be understood triply, as (1) a postulate of the social good, (2) materially, as an object of collective ownership, and (3) as an effect of the individual’s life in society, then it must be admitted that, at least in the third case, reference to the collected achievements of sociology is necessary in order to describe the common good properly.
High-intensity Interval Training as an Effective Method for Improving Non-athletic Students’ Physical Fitness
Authors: Жукова В.В. 
Published: May 2021

Аннотация. В статье рассматривается вопрос улучшения показателей уровня физической подготовленности студентов высших учебных заведений не физкультурных специальностей в возрасте 17–18 лет.
Разработано и представлено содержание методики интенсивно-интервального тренинга для оптимизации процесса физического воспитания студентов на занятиях физической культурой, а также комплекс упражнений по системе интенсивно-интервальной тренировки.
На основе результатов педагогического эксперимента доказана гипотеза о том, что применение средств интенсивно-интервального тренинга на занятиях физической культурой со студентами высших учебных заведений нефизкультурных специальностей способно значительно повысить уровень их физической подготовленности и степень развития базовых физических способностей.
Доказательство эффективности применения средств интенсивно-интервального тренинга для повышения уровня физической подготовленности этих студентов определяет новизну проведенного авторами исследования, обогащение теории физической подготовленности студентов, в том числе развития таких физических качеств, как выносливость, сила и координация движений. Выявляется также его теоретическая значимость,
а возможность практического использования педагогами в процессе организации и проведения занятий по физической культуре свидетельствует о практической ценности.
The article focuses on the issue of improving physical fitness and stamina of 17–18-year-old non-athletic students of higher education institutions.
The author of the article has developed and presents a high-intensity interval training program aimed at enhancing students’ physical fitness through HIIT workouts during physical education classes in higher education institutions.
The results of pedagogical experiment prove the hypothesis that HIIT workouts during physical education classes in higher education institutions help enhance non-athletic students’ physical fitness and improve their physical abilities.
The fact that high-intensity interval training workouts help enhance students’ physical fitness, stamina, motor coordination and muscular strength accounts for the novelty and theoretical significance of the research. The practical significance of the research is accounted for by the fact that its results can be used by classroom teachers to plan physical education lessons in higher education institutions.
