Authors: Mandal Sukumar , Malik Sailendra
Published: November 2020

Copy cataloguing and Z39.50 are well known concepts in modern library environment for executing library functions and activities. Data import is possible from different library OPACs using the Z39.50 server. Online Computer Library Centre (OCLC) and Library of Congress (LoC) are among the most comprehensive OPAC databases. This paper attempts to design a framework for comparison of Z39.50 search available in public domain and implementation of information retrieval protocol facilities in open source ILSs. The framework is mainly based on recommendations given by ILS-DI and IFLA Working Group on the area under consideration. It considers how to import the records from the other databases or OPAC through Z39.50 server or SRU/W towards next generation automation. Two open source ILSs (from the matured block of ILSs) namely NewGenLib and Koha are compared against a set of search parameters related with Z39.50 and drawn from global recommendations.

Growth Dynamics Study of Proteomics Research Output Since 2000 to 2018
Authors: Teli Soumen , Dutta Bidyarthi
Published: November 2020

Proteomics is the large scale of study of proteins with their function and structure. It is an approach for studying changes in metabolism in response to different stress conditions. It indicates the entire set of proteins that is, or can be, expressed by a genome, cell, tissue, or organism at a certain time. In India, the term ‘Proteomics’ was first used in an article on genomics in 1999. This paper presents the growth dynamics study of Indian and global proteomics research output with a comparative analysis. The growth pattern in India during 1999 to 2007 was exponential in nature followed by saturating power model, while the same for global research showed exponential pattern, followed by the saturating logarithmic curve. The speed of Indian growth was fast compared to global growth since after 2008 as evident from the magnitudes of AIS/AGS. The growth patterns followed Price’s law with an initial exponential trend followed by saturation thereafter. The magnitudes of the Activity Index over the years shows that Indian proteomics research is still far below the world average level, though the lowest AI in the year 2001 (0.002) escalated 19.5 times in 2015 (0.039). The Attractivity Index (AAI) values are found less than one indicating lower than world average impact values of Indian proteomics research, though it is continuously growing.

Aim        To analyze results of changing the management tactics in patients with acute coronary syndrome (ACS) in clinical practice from 2004 through 2018 expressed as improvement in prognosis.

Material and methods        Results of two observational studies were analyzed: ORACLE I (2004–2007), which included 1193 patients with ACS (mean age, 61.1±11.69 years; men, 63.3 %) and ORACLE II (2014–2017), which included 1652 patients from 4 vascular centers (mean age, 64.61±12.67 years; men, 62.3 %).

Results   Patients included into the ORACLE II study in 2014 were significantly older and the proportion of patients with diabetes mellitus was greater than in the ORACLE I study (14.7 and 22.6 %, respectively). After matching the groups by major clinical characteristics, it was found that introducing the invasive management tactics for ACS patients was associated with a reduced rate of all-cause death (from 8.2 to 6.1 % for one year), a tendency towards decreased number of coronary death cases (from 5.6 to 4.0 %), and a decrease in risk of recurrent coronary complications (from 17.4  to 7.7 %).

Conclusion            Implementing the vascular program statistically significantly decreased the total death rate for at least one-year observation in comparable patient groups.

Published: November 2020

Aim To compare efficacy and safety of direct oral anticoagulants (DOACs) for prevention of stroke in patients with nonvalvular atrial fibrillation and reduced creatinine clearance.Material and methods Systematic search for literature and indirect comparison of DOACs were performed.Results The indirect comparison included five randomized clinical trials. The DOACs were comparable by the efficacy of preventing stroke and systemic embolism. The safety profiles had differences. Apixaban significantly decreased the relative risk of major bleeding compared to rivaroxaban by 27 % (relative risk (RR) 0.73; 95 % confidence interval (CI): 0.55–0.98). The apixaban advantage was even greater in the group of patients with a creatinine clearance <50 ml/min: RR was reduced by 48 % compared to rivaroxaban (RR=0.52; 95 % CI: 0.32–0.84), by 50 % compared to dabigatran 300 mg/day (RR=0.50; 95 % CI: 0.31–0.81), and by 48 % compared to dabigatran 220 mg/day (RR=0.52; 95 % CI: 0.32–0.85)Conclusion The indirect comparison of DOACs showed that their efficacy was comparable. With respect of safety, apixaban is the preferrable DOAC for patients with atrial fibrillation and creatinine clearance below 50 ml/min.

Aim To evaluate results of three-year follow-up in patients after acute coronary syndrome (ACS) associated with chronic obstructive pulmonary disease (COPD) and to identify predictors for delayed serious cardiovascular adverse (SCVAE) events.Material and methods This prospective cohort study included 119 patients with verified COPD who had ACS after a successful urgent percutaneous coronary intervention and were discharged from the hospital without in-hospital complications. Incidence of and time to SCVAE (cardiovascular death, myocardial infarction, stroke, repeated unscheduled myocardial revascularization) were recorded. SCVAE predictors were identified with the Cox regression by stepwise inclusion of variables into the model.Results SCVAE occurred in 33.6 % of ACS patients with COPD. The high rate of repeated myocardial revascularization mostly contributed to the development of delayed SCVAEs (19.3 % of patients). Independent predictors of SCVAE included the total number of stenoses in major coronary artery branches; ankle-brachial index; glomerular filtration rate calculated with the CKD-EPI equation; frequent COPD exacerbations; functional residual capacity of the lungs; and 6-min walk distance.Conclusion New independent predictors of SCVAE were identified in COPD patients after ACS with percutaneous coronary intervention and stenting, including distance in the 6-min walk test, frequent COPD exacerbations, and functional residual volume of the lungs as an index of pulmonary hyperinflation.

The article is devoted to the treatment of the new coronavirus infection (COVID-19) in the advanced stages of the disease. The types of response of the immune system to the viral load of SARS-CoV-2 with the start of the inflammation process are considered. The situation is analyzed in detail in which the growing autoimmune inflammation (up to the development of a "cytokine storm") affects not only the pulmonary parenchyma, but also the endothelium of the small vessels of the lungs. Simultaneous damage to the alveoli and microthrombosis of the pulmonary vessels are accompanied by a progressive impairment of gas exchange, the development of acute respiratory distress syndrome, the treatment of which, even with the use of invasive ventilation, is ineffective and does not really change the prognosis of patients with COVID-19. In order to interrupt the pathological process at the earliest stages of the disease, the necessity of proactive anti-inflammatory therapy in combination with active anticoagulation treatment is substantiated. The results of the first randomized studies on the use of inhibitors of pro-inflammatory cytokines and chemokines (interleukin-6 (tocilizumab), interleukin-17 (secukinumab), Janus kinase blockers, through which the signal is transmitted to cells (ruxolitinib)), which have potential in the early treatment of COVID- 19. The use of a well-known anti-inflammatory drug colchicine (which is used for gout treatment) in patients with COVID-19 is considered. The design of the original COLORIT comparative study on the use of colchicine, ruxolitinib and secukinumab in the treatment of COVID-19 is presented. Clinical series presented, illustrated early anti-inflammatory therapy together with anticoagulants in patients with COVID-19 and the dangers associated with refusing to initiate such therapy on time.

The left three-atrial heart (LTH) is a rare congenital abnormality where the left auricle (LA) is divided into two chambers with an additional membrane. This article describes for the first time a clinical case of congenital heart defect with four atrial chambers. A 41-old man was hospitalized for newly diagnosed paroxysmal atrial fibrillation. On transthoracic echocardiogram (EchoCG), LA was considerably enlarged and divided into two equal interconnected parts with a membrane. Additional examination with contrast-enhanced EchoCG and computed tomography revealed two membranes dividing the LA into three chambers. Prediction for the patient was beneficial since there were no other developmental abnormalities of the heart, and the LA transmembrane pressure gradient (PG) was small. Data of literature on the incidence and prognosis of LTH are provided.

Published: November 2020

Background: Critically ill eclampsia patients present a unique challenge to the obstetrician, anesthesiologist and intensivists. In developing countries, maternal mortality is still high due to lack of good maternal antenatal services and obstetric intensive care. This study aims to provide a comprehensive review for the management and outcome of critically ill eclampsia patients admitted in the obstetric intensive care unit (ICU), GMC, Bhopal.Methods: This study was a hospital based cross sectional study. The study included 145 eclampsia patients who were admitted in obstetric ICU for critical care management. For each eligible patient, sociodemograhic profile, indications of ICU admission, data on ICU interventions and maternal outcome were documented.Results: During study period, total obstetric admission were 19,815 and 14,731 live births. Out of 348 eclampsia patients, 145 patients were admitted to the obstetric ICU, giving an ICU admission rate of 9.8/1000 live births. 98.03% patients were unbooked referred obstetric emergencies.The average duration of stay in obstetric ICU was 5.4+3.1 days. 72.9% patients had antepartum eclampsia, 17.2% patients had postpartum eclampsia and 10.8% patients had intrapartum eclampsia. 41% patients received mechanical ventilation, 90% patients received oxygen and advanced monitoring, 48.6% patients received vasoactive drugs and 53.7% patients received blood transfusions. There were 26 maternal deaths giving a case fatality rate of 17.93%.Conclusions: Early referral of eclampsia patients or at risk patients to a tertiary care centre may help to reduce maternal morbidity and mortality. Early diagnosis and prompt treatment through a multidisciplinary team in an ICU setting can prevent complications and reduce morbidity and mortality.

Published: November 2020

Fish is one source of high protein and included a commodity which is easily to decay. The way to inhibit the decay process of fish is fumigation. One of the smoked fishes that is often consumed by Gorontalo people is smoked Roa fish (Hemiramphus sp.). Smoked Roa fish is processed with traditional way through burning using woods as the fuel. Simply or conventionally fish processing like that has several flaws such as less protected of the sanitation aspects in the processing protocol. In order to improve the traditional processed product of Gorontalo, that is a smoked Roa fish, a new breakthrough in making smoked Roa fish was made by using the liquid smoke method. Liquid smoke contains compound of phenol and organic acids that are antibacterial and antioxidant compounds. The purpose of this research is to evaluate the effect of using different fumigation methods on organoleptic quality (appearance, smell, taste, and texture) of smoked Roa fish. The fumigation methods used were fumigation with liquid smoke and fumigation with traditional method. This research used a completely randomized design with 2 treatments and 3 times of replications. The results showed that liquid smoked Roa fish were preferred by panelists, compared to traditional smoked Roa fish. Liquid smoked Roa fish had a bright appearance, the smoke color was spread evenly (uniform), the smell of soft smoke, delicious fish taste, and hard texture that were different from traditional smoked Roa fish which appearance tended to be dull, the color of the smoke was not evenly distributed, the smoke taste in the fish was also quite sharp. Liquid smoked Roa fish also had a lower water content than traditional smoked Roa fish. Statistical tests showed that the fumigation method had a significant effect on the smell and water content of smoked Roa fish.

Published: November 2020

Cinchona ledgeriana Moens is an industrial plant producing secondary metabolite quinoline alkaloids. To maintain and moreover, to increase the quinoline production especially quinine, in vitro culture system through cell culture could be a potential alternative. If the use of elicitor in cell culture can increase the production of a secondary metabolite, the activity of the enzymes involved in the biosynthetic pathway of the secondary metabolite in question might be increasing. This study aimed to examine the activity of NADPH oxidoreductase in the elicitated cell culture of C. ledgeriana and to evaluate the correlation between the activity of this enzyme and the level of quinine production. The cell cultures of Cinchona were treated with abscisic acid (ABA) or paclobutrazol (PBZ), combined with sucrose, sorbitol, or mannitol in Wood Plant (WP) media, for 7 weeks on a shaker. The quinine concentration was determined using high-performance liquid chromatography (HPLC) and the enzyme activity was measured using fluorometry. The results showed that the highest enzyme activity was found in the P7M cells (PBZ 7 mg/L + mannitol 5.3 g/L + sucrose 20 g/L), followed by the A3S cells (ABA 3 mg/L + sorbitol 5.3 g/L + sucrose 20 g/L). These results correspond to their production level of the quinine alkaloids. The lowest enzyme activity was found in the cultures without elicitor. The increase of NADP(H) enzyme activity in the P7M and A3S treatments were 13.5 and 8.5%, respectively, compared to that in the control cells.

The mangrove ecosystems on the coast of Sayung Sub-District provide huge benefits to the community. However, this region experienced a very severe coastal erosion during the last few decades. Also, information about mangrove ecosystem services is still very limited in this region. The purpose of this study, therefore, was to map the balance of mangrove ecosystem services on the coast of Sayung Sub-District, Demak District. Data were collected from three coastal villages, namely Bedono, Timbulsloko, and Surodadi, through in-depth interviews, questionnaires, and field observations. The data analysis was carried out using the Burkhard model approach, which involved an ecosystem service matrix, made up of a matrix of capacity, demand, and availability. The results showed that in all components of provisioning service, there was a surplus of availability. In regulating services, there were low surpluses in the components of carbon sequestration and water bioremediation services, while low deficits were found in the service components of reduce wave and current damage, and protecting from sea water intrusion. Then, in cultural services, the two components, shelter for rest area and recreation, experienced a surplus of availability. Mangrove rehabilitation needs to be continued to increase mangrove cover, given the availability of regulating services on components related to erosion prevention in the balace sheet tends to be deficit.

Moringa oleifera is a plant that has many benefits in each part. Moringa seeds have high nutrient content but they have not been used as food ingredients because it contains cyanigenic glycoside and a bitter taste. This study aims to obtain the best method in eliminating the bitter taste and cyanide of moringa seeds, analyzing its proximate nutritional levels and antioxidant capacity, and the level of acceptance when it’s applied to cookie products. This study used different types of soaking solution (water, 3.5% NaCl, 1N CH3COOH solution, and 0.5% NaHCO3) and boiling temperature (70°C, boiling water temperature (± 97°C), and pressure boiling (±115°C)). Flour with NaHCO3 immersion treatment continued by pressurized boiling for 35 minutes was chosen to be the best flour because it had the lowest cyanide content, reduced bitter taste, and the highest FRAP (Ferric Reducing Antioxidant Power) values (33.40±1.22 mg/kg; 3.40±1.24 mg/kg; and 58.70±2.67 mg AEAC/g) compared with untreated moringa seed flour (152.15±0.95 mg/kg ;10.29±2.92 mg/kg; and 17.43±1.22 mg AEAC/g). The selected flour was used as a substitute for flour (0%, 10%, 20%, and 30%) in cookies making. Sensory hedonic rating analysis on cookies used 60 untrained panelists. Substitution up to 30% overall did not have a significant difference in acceptance compared to control (0%) except for color attribute.

Published: November 2020

The study demystified the places in Cebu named after an endemic flora. To answer the main problem, the following objectives were raised: (1) determine the clusters of flora used in the naming of places in Cebu, (2) identify the reasons why the barangays, towns, and cities are named after a specific flora; (3) describe the local stories of the communities as regards to the naming of places, (4) ascertain the local government intervention to promote the identity awareness of their places, and (5) design indigenized teaching models for instruction. This qualitative study used a hermeneutics analysis design, which focuses on interpreting the data gathered from the various key informants. The interview guide was used. Responses were transcribed, clustered, and analyzed. Places in Cebu named after endemic flora contained valuable insights regarding time and place in the past; it served an emblem of identity. The abundance of a certain species in the environment, language variation, miscommunication, colonization and the similarity of the colonizers’ place of origin were the factors in the naming of places. Government action and implementation are great advantages in the preservation of place-names. A vibrant way to preserve it in the classroom setting is contextualizing these endemic floras through indigenized NBC teaching models: Narra, Balili, and Cogon created a unique repertoire of teaching and its stories ignited students’ interest in learning and nuanced familiarity in the preservation of the community’s identity and pride of place.

Como se conoce, en medio de la campaña electoral de los Estados Unidos y de uno de los peores momentos de la relación entre Estados Unidos y la República Popular China, el Secretario de Estado Mike Pompeo tomó la decisión de acortar su viaje previsto a Japón, Mongolia y Corea del Sur (el viaje a esos últimos países se pospuso para fines de octubre), para entre el 4 y el 8 de octubre, concretando reuniones con los Ministros de Relaciones Exteriores de los países del denominado “Quad” (Australia, India, Japón, junto a Estados Unidos), entre el 4 y el 6 de octubre, en Tokio, a pesar de que la reunión original estaba planeada para realizarse en Nueva Delhi (India) (Toya, 2020). Este Diálogo Cuadrilateral de Seguridad, es un foro estratégico informal entre estos cuatro países, que mantienen encuentros/cumbres con cierta regularidad, al tiempo que realizan ejercicios militares e intercambian información. Fue iniciado en el año 2007, por el Primer Ministro de Japón, Shinzo Abe, como un diálogo, bajo la visión de un "arco de libertad y prosperidad" para los países ribereños de los océanos Índico y Pacífico. Ese grupo de países se había reunido en 2004 para la tarea de ayuda tras el tsunami del Océano Índico de ese año, formándose así la base del foro que se disolvió luego de finalizar los esfuerzos humanitarios.

Abstract

Academic achievement is considered as one of the major factors in the learning process, as it is one of the complex variables that have an important influence on learning. The purpose of the current study was to investigate the relationship between academic motivation, academic help-seeking and academic achievement. A total of 437 university students were selected randomly (simple random–online questionnaires) from many Arab countries (Jordan, Kingdom of Saudi Arabia, United Arab Emirates and Syria) who responded to the questionnaire on academic motivation (intrinsic, extrinsic and amotivation) and academic help-seeking (instrumental, executive, avoidance and benefits of help-seeking). Path analysis results showed direct effects from intrinsic motivation to instrumental help-seeking (0.291**), amotivation to executive help-seeking (0.709**), instrumental help-seeking to grade point average (GPA) (0.377**), executive help-seeking to GPA (−0.349**), intrinsic motivation to benefits of help-seeking (0.528**) and from amotivation to avoidance help-seeking (0.738**). Also, there were indirect effects from amotivation to GPA (−0.248**) and from intrinsic motivation to GPA (0.110**). The results illustrate the importance of academic motivation and help-seeking to provide a fuller understanding of students’ academic achievement.

Achieving the state’s geopolitical goals and extending its economic influence assumes its inclusion into modern multimodal corridors, their efficient usage and control, this enabling to restrict economic expansion of countries-competitors, weaken economic dependence on other states and increase its own presence at regional and world markets. The necessity of full-scale use of transit potential due to Russia’s geographical location as a natural transport corridor, connecting European region with Asia-Pacific region, is the main condition for implementation of RF transport strategy. From the viewpoint of geopolitical benefits, an important stage of Russian railways development in the context of world logistics may turn out to be implementation of such important transport and logistics projects as cooperation with China and other Asian countries in laying a Transpolar mainline. The first project assumes creation of a reliable and efficient mechanism of railway traffic between Europe and Asia on the Trans-Siberian railway. A further link in this chain should become established cargo shipping on the Northern sea route, as an important geopolitical benefit for the Russian Federation lies foremost in strengthening of its presence in Northern and Arctic zones. A fight for the Arctic coast is first of all the fight for the most important transoceanic communications - the Northern sea route and Northwest passage connecting the Atlantic and Pacific.

The lung ultrasound in differential diagnostic of acute respiratory failure reason
Authors:   Prof. V. F. Voino-Yasenetsky Krasnoyarsk State Medical University, Kuzhel D.A.
Published: November 2020

Ultrasound lungs examination has been considered uninformative for decades due to the high acoustic resistance between soft tissues and airy lungs. Recently, the work in emergency conditions has proved the usefulness of ultrasound technologies, especially while diagnosing acute respiratory failures. Introduction of ultrasound technologies into the practice of intensive care units made it possible to change the ‘philosophy’ of diagnosing critical conditions, promoting ultrasound as primary technique, even in the era of widespread use of computed tomography. Portable ultrasound diagnostic devices, along with general clinical examination, made it possible to differentiate rapidly such acute conditions as cardiogenic shock, acute respiratory distress syndrome, pneumothorax, atelectasis, and other lung lesions

Patients with myocardial infarction (MI) and atrial fibrillation (AF), the number of which is progressively increasing every year, make up a high-risk group for both recurrent cardiovascular events and bleeding; they require special attention from clinicians. The literature review provides data on features of pathogenesis and clinical manifestations of MI in patients with AF. The analysis of data on AF effect observational studies on short-term and long-term prognosis in patients with myocardial infarction was carried out. Mechanisms of occurrence, clinical features and prognostic value of postinfarction AF are considered. From the standpoint of modern clinical guidelines, information is presented on features of MI invasive treatment in combination with AF. Algorithms of anticoagulant and antiarrhythmic therapy in patients of this category are considered.

Features of conceptual and categorical apparatus of ruling elite of modern Russia (based on publications by representatives of political party “United Russia”)
Authors:   National Research Technological University “MISiS”, Kozyrev M.S.
Published: November 2020

Researched are characteristics of social position of the ruling Elite in Modern Russia. As an object of analysis, used are publications by representatives of the political party “United Russia”, as well as address by the president of the Russian Federation to the Federal assembly of the Russian Federation. The methodological basis of the work is scientific development of K. Mannheim, according to which a certain social position determines a certain type of thinking. Analysis of documents (classical document analysis and content analysis) was used as method for obtaining information. The key concepts of ideological discourse were identified with the Soviet Union, efficiency, competition, stability, responsibility. Based on results of the analysis, conclusions were drawn about peculiarities of social position of the ruling elite: it is generally satisfied with its position in Russia, and therefore their main task is to preserve it. Practical field of activity of the Russian elite is the struggle for resources, which does not imply total change in the social system. The elite is not homogeneous and it’s groups are in a state of constant competition with each other for the possession of “status rent”, the main resource of the ruling elite (one of the main ones), through which it ensures it’s exclusive position, are imperious, and the main type of relations is hierarchical. This does not exclude existence of elite groups independent of the center. However, the main, system-forming type of relationship is hierarchical.

Published: November 2020

A morphological and morphometrical study is performed on a collection of kuehneotheriid isolated molars (uppers and lowers) from the Late Triassic of Saint-Nicolas-de-Port (Meurthe-et-Moselle, France). It is shown that individual and random variability is dominant in this hypodigm and that, for this reason, no specific trend can be recognised which could validly isolate it taxonomically from the British taxon Kuehneotherium praecursoris. Wear facets are analysed and a progressive wear series as well as the occlusion pattern are reconstructed.
MODELING THE NUMBER OF MULTIBACILLARY LEPROSY USING NEGATIVE BINOMIAL REGRESSION TO OVERCOME OVERDISPERSION IN POISSON REGRESSION
Authors: Wibisono Fitri Anugerahani , Kurniawati Eva R.
Published: November 2020

Poisson regression is used on discrete data (count) for the formation of the model. There is often a violation in Poisson regression analysis assumptions i.e., overdispersion, which means the average value of the data is smaller than the value of the variance. The number of multibacillary leprosy (MB) in 31 Surabaya districts orderly from 2015 to 2017 has increased as many as 127 cases, 140 cases, and 158 cases. This study aimed to model the number of MB leprosy in Surabaya in 2017 with a Negative Binomial regression in overdispersion. This was quantitative research with a descriptive method that uses secondary data. The data sourced from Surabaya City Health Profile in 2017. The independent variables studied include BCG immunization coverage, the percentage of healthy houses, the percentage of Households with Clean and Healthy Behavior (HCHB), the percentage of the male population, and the population density level. MB leprosy incidence modeling with Poisson regression proved to be overdispersed so that the Negative Binomial regression was used to overcome it. The variable that influenced the MB leprosy incidence with a Negative Binomial regression analysis was the percentage of healthy houses (p = 0.019). MB leprosy occurence will decrease if the percentage of healthy houses increases. The percentage of healthy houses in Surabaya was 86.99%, which increased compared to the previous year with an increase of 1.78%. Public awareness about healthy houses is required to reduce the number of MB leprosy in Surabaya.

Published: November 2020

The signs of puberty in teenagers are including physical changes such as breast development (thelarche), pubic hair growth (pubarche) and armpits, menarche, and ovulation. Menstruation that occurs for the first time is known as menarche. Teenagers facing menarche require good preparation since anxiety and fear will likely appear. Anxiety that occurs makes teenagers experience selective attention that disrupts their concentration. Preliminary studies that have been conducted by researchers are known to have elementary school students who experience anxiety facing menarche in Pademawu (sub-district) as the subjects. This study aims to analyze the relationship between readiness and anxiety level of elementary school students facing menarche in Pademawu, Pamekasan (district). The quantitative cross-sectional study is a research design chosen by researchers. The number of research samples of 75 students was obtained through cluster random sampling. The clusters used as research samples are in different schools and the same sub-district. Multinomial logistic regression is a statistical test for analyzing data. The results of the study were 49.3 percent of students had sufficient knowledge about menarche. As many as 38.7 percents of students received family support about moderate menarche. Furthermore, 68 percent of students were not ready to face menarche, and 45.3 percent of students experienced moderate anxiety. In the statistical test results obtained a correlation value of 0.001. In this research, it is known that there is a relationship between readiness and anxiety level in dealing with menarche in elementary school students in Pademawu, Pamekasan. Family willingness and support are factors that influence respondents' anxiety in facing menarche. Parents are expected to be active in educating their daughters by providing information and motivation in dealing with menarche.

Published: November 2020

Introduction: SARS-CoV-2 RNA transmission in wastewater has a risk of fecal transmission ofSARS-CoV-2 to humans and the environment. Despite the increasing number of cases in almostall areas in Indonesia, the study to review and evaluate waste management resulted from medicalfacilities is still limited and less explored. This literature review aims to analyze the applicabilityof WHO guidelines on wastewater management to be implemented in Indonesia. Scientific paperswere collected from several electronic databases such as PubMed, PLoS, Researchgate, WHO,Elsevier, Science, SARS-CoV-2, Covid19, and wastewater. The articles were selected based on theinclusion criteria that use SARS-CoV-2, Covid19, and wastewater as the main variables observed.The articles published before 2013 were excluded from this review. Discussion: Wastewatermonitoring of SARS-CoV-2 within medical and health facilities is implemented to identify thevirus’s presence as the causative agent of Covid19 disease, which contaminated the environmentand society. The results of the analysis in wastewater can be used to determine the infectioncontrol in health facilities while also beneficial in formulating the monitoring of environmentalimpacts caused by the waste. These efforts would support policies or interventions based on publichealth by applying social distances, locking, quarantine areas that aim to break the Covid19transmission. Conclusion: Briefly, by considering the urgency of Covid19 pandemic containmentand control measures of transmission in health facilities, population and environment. It is a wastemanagement guideline that is highly required to be implemented based on public health aspects.
