Binary Adsorption Studies of Toxic Metal Ions of Lead and Copper from
Aqueous Solution by Modified Foeniculum vulgaris Seeds (Fennel Seeds)
Authors: Mabungela Ntandokazi , Shooto Ntaote David , Mtunzi Fanyana , Naidoo Eliazer Bobby
Published: June 2021

Discharge of copper(II) and lead(II) ions into rivers and streams by industries and other human activities
has gained serious consideration from regulatory bodies. These toxic metals are harmful to human
beings and aquatic life when in high concentrations. Therefore, their removal from wastewater is very
important. Hence, this work reports the binary adsorption of toxic metal ions of Cu(II) and Pb(II) from
aqueous solution by pristine and modified fennel seeds. Pristine fennel seeds (PFS) were treated with
acidic and alkaline solutions to develop modified adsorbents designated ATFS and BTFS, respectively.
SEM images revealed that PFS had an amorphous surface with irregular cavities. However, upon acid
and base treatment, the surface was more refined. The ATFS had interconnected pores while BTFS
had somewhat honeycomb pores. The UV-Vis results confirmed that some of the components were
removed from PFS during acid and base pre-treatment. FTIR spectra revealed that the adsorbents had
functional groups such as (-OH) and (-C=O), which were involved in the uptake of the metal ions. It
was observed that the uptake of Cu(II) and Pb(II) ions onto all adsorbents progressively increased
when the initial concentration of the solution was increased. The maximum adsorption capacity was
obtained when the initial concentration of the solution was 100 mg/L. The uptake of Cu(II) and Pb(II)
on PFS was 3.345 and 11.524 mg/g. While for ATFS 3.78 and 13.07 mg/g and BTFS 8.143 and 14.85
mg/g, respectively. It was observed that the isotherm data fitted Freundlich better for the uptake of
both metal ions onto all adsorbents. It was observed that there was a rapid uptake when contact time
increased from 5 to 60 min. However, when time increased above 60 min the uptake stabilized and
reached equilibrium this was due to the saturation of active sites on the surface for all adsorbents. The
kinetics study revealed that PSO fitted the data better than PFO. IPD data revealed that the uptake of
metal ions was controlled by the synergistic of ESA and EPA. The ΔHº values for Cu(II) and Pb(II)
uptake onto all adsorbents were all negative. This suggested that the reactions were exothermic.

Published: June 2021

Resumo: Com o objetivo de refletir sobre a questão identitária através das máscaras enquanto elemento artístico e cultural com amplo potencial pedagógico, este artigo problematiza a questão da construção de saberes através das contribuições da teoria da decolonialidade, fundamentando-se para tanto no trabalho com máscaras realizado através da oficina intitulada Máscara e Identidade: nós no PIBID (2017). Desse modo, ressalta-se a relevância dos saberes subalternos enquanto resistência a imposições epistemológicas oriundas de uma ciência europeia que visam silenciar as vozes dos indivíduos subalternos (QUIJANO, 2010; SANTOS, 2010), bem como restringi-los em suas possibilidades construir sua identidade e sua subjetividade através de um sistema representacional que integre suas vivências, suas experiências e seus conhecimentos.
Temporalidades e deslocamentos na inclusão de sujeitos com cegueira em uma escola visuocentrada
Authors: Frey Riffel Birgit Yara , Mendes Jackeline Rodrigues
Published: June 2021

A inclusão de pessoas com deficiência na escola regular vem se consolidando no Brasil contemporâneo, trazendo consigo mudanças significativas no cotidiano escolar. O objetivo deste artigo é problematizar – especificamente no campo de jovens com cegueira – esta inclusão, interrogando as formas como tem ocorrido, com quais objetivos e conexões, tentando compreender as diferentes subjetividades a que este grupo social é submetido. Isto não significa, entretanto, se opor à inclusão, mas situá-la dentro de um contexto de relações de poder e produções discursivas, de forma que nos permita perceber seus efeitos sobre a constituição dos sujeitos. A interpretação destes elementos leva a considerar que as políticas públicas atuais podem estar conduzindo os sujeitos a uma condição de autorregulação, normalização e competição, principalmente ao se vincular a preceitos visuocentrados.
Políticas de inclusão e os efeitos nas práticas docentes no ciclo de alfabetização
Authors: Klein Rejane Ramos
Published: June 2021

Este texto discute sobre as políticas de inclusão e os efeitos nas práticas alfabetizadoras desenvolvidas nos anos iniciais da escolarização. Parte-se de uma pesquisa intitulada Alfabetização na “idade certa” numa perspectiva inclusiva: tensões e desafios às práticas docentes alfabetizadoras (2016-2019/FAPERGS), para analisar práticas de professoras que atuam nos Anos Iniciais do Ensino Fundamental em escolas municipais localizadas no estado do Rio Grande do Sul. Considera-se que as políticas de inclusão produzem efeitos nas práticas alfabetizadoras ao instigar as professoras a individualizar os sujeitos e a flexibilizarem o currículo a fim de garantir a alfabetização de todos na idade certa. Compreendem-se estas práticas na perspectiva da in/exclusão como produzidas pelos discursos que constituem os sujeitos incluídos em uma sociedade neoliberal.
Nascent Entrepreneurs, Entrepreneurial Self-Efficacy, and the Moderators of Race, Gender, and Government Support
Authors: Cavich Jason , Chinta Ravi
Published: June 2021

In a better attempt to understand nascent entrepreneurship, this paper explores the relationship between opportunity recognition and the entrepreneurial intent of nascent entrepreneurs. Contrary to conventional wisdom, research on this relationship is fragmented and empirically underdeveloped. In addition, the contextual and perceptual boundary conditions of government support, gender, and minorities are explored. We surveyed 1246 nascent entrepreneurs in the state of Florida, which is the largest data set on this topic in Florida. Respondents answered 55 survey questions on potential barriers to entrepreneurship to help understand how their context impacts their intent to start a new business. Our empirical results indicate that opportunity recognition by nascent entrepreneurs significantly affects entrepreneurial intent, the strength of which is moderated by government support and gender, but not by minorities. Our study is a direct response to the call-in existing entrepreneurship literature for new research in geographically narrower contexts as the largest survey-based study at the state level in the US that we know of. We extend and demarcate entrepreneurial self-efficacy into a new context while clarifying boundary conditions. Lastly, our dependent variable measures intensity of intention to start a business along a time dimension which empirically narrows the gap between studies on entrepreneurial intention and studies on entrepreneurial action.
The Role of Entrepreneurs’ Empathy in New Venture Performance: The Mediating Effects of Entrepreneurial Orientation
Authors: Zhao Wenhong , Lyu Siyao , Sekiguchi Tomoki
Published: June 2021

Previous research has found that entrepreneurs’ empathy promotes personal opportunity identification. However, the role that entrepreneurs’ empathy plays at the firm level in new ventures is still unclear. This study explores this question by investigating how perspective taking and empathic concern, which respectively represent the cognitive and affective component of entrepreneurs’ empathy, influence new venture performance with the mediating effects of entrepreneurial orientation (EO). Based on an empirical study with 341 new ventures, this research finds a positive relationship between perspective taking and new venture performance and a curvilinear relationship between empathic concern and new venture performance. In addition, both of these relationships are mediated by EO. This study sheds light on distinct impacts of the entrepreneur’s perspective taking and empathic concern at the firm level, enriches the antecedents of EO from the cognitive and affective factors of the entrepreneur, and extends the implications of the entrepreneur’s altruistic dispositions in commercial start-ups.

Authors: Bokhary Syed Ahtsham Ul Haq , Adnan
Published: June 2021

The Wiener index, due to its many applications is considered to be one of very important distance-based index. But the Padmaker-Ivan (PI) index is kind of the only distance related index linked to parallelism of edges. The PI index like other distance related indices has great disseminating power. The index was firstly investigated by Khadikar et al. (2001), they have probed the chemical applications of the PI index. They proved that the proposed PI index correlates highly with the physicochemical properties and biological activities of a large number of diverse and complex chemical compounds and the Wiener and Szeged indices. Recently, the vertex Padmarkar-Ivan (PIv) index of a chemical graph G was introduced as the sum over all edges uv of a molecular graph G of the vertices of the graph that are not equidistant to the vertices u and v. In this paper, the vertex PIv index of certain triangular tessellation are computed by using graph-theoretic analysis, combinatorial computing, and edge-dividing technology.
Characterization of dairy sheep farms in the Serra da Estrela PDO region
Authors: Monteiro António , Santos Sérgio
Published: June 2021

Sheep farming plays a key role in the sustainability of the most depressed rural regions of Portugal, particularly in the Serra da Estrela region, and is recognized as an important source of income for many local farmers. Thus, the management of local sheep breeds in the region has over generations given rise to its most emblematic product: Serra da Estrela cheese, with Protected Designation of Origin (PDO). This study aims to briefly describe the sheep farms producing certified milk in the Serra da Estrela region. To this end, a survey form was drawn up and applied to 75 farms, randomly selected, from the defined geographical area of Serra da Estrela, from June to August 2020. The results show that the producers, mostly male, have an average age close to 51 years. On average, the herd size is equal to or greater than 100 animals and the daily milk production per animal varies between 0.47 and 1.0 L. The price of milk paid to the producer is, on average, at 1.25 Euros/L. Both the average herd size and the lactation length are higher than those described by others. The average daily milk production in most of these farms is in accordance with the standard average value related by other authors.

Continuity of Carolingian Judicial Institutions in Ottonian Lotharingia
Authors: Bachrach David S.
Published: June 2021

The institution of the scabini, men from the pagus who served as legal fact finders in comital courts, was established by Charlemagne in the later eighth century and has received considerable attention from scholars for well over a century. Much of the early debate about the scabini focused on the origins of the institution, and whether Charlemagne was successful in replacing the previous ad hoc administration of justice with more formal procedures that followed more closely on the dictates of the royal court. A second important element in the historiography has focused on the fate of the institution of the scabini following the end of Charlemagne’s reign, and particularly after the division of the unitary empire following the death of Louis the Pious in 840. Many scholars, following the lead of F.L. Ganshof, have argued that the institution of the scabini, and governmental courts more generally, ceased to function at some point in the later ninth century, to be replaced by so-called feudal courts. The following study challenges this latter model by examining the institution of the scabini under the later Carolingians and their Ottonian successors in the region of Lotharingia, which gained a long-standing political coherence following the brief reign of King Lothair II (854–869). This region was the scene of intense political and military conflict throughout much of the period from the later ninth through the early eleventh century. Nevertheless, numerous private and royal charters of the Carolingians and Ottonians, as well as ostensibly prescriptive texts included in royal capitularies, point to the continuity of the institution of the scabini during the entirety of the Ottonian period from ca. 919–1024.
II. Causa und titulus
Authors: Pool Eric H.
Published: June 2021

Causa and titulus. Qualifications of possession and a change of terminology in Ulp. D. 5,3,13,1. – In D. 5,3,13,1, Ulpian states that every title to possession (like pro emptore, pro donato etc.) could be accompanied by a general title pro possessore, which becomes decisive if the other title failed. The text is interesting in two aspects: First, it is one of only a handful of classical texts which speak of titulus instead of causa possessionis. Therefore, the text is still today suspected of interpolation. Second, it is heavily disputed which circumstances lead to a possession pro possessore and why this typolology is used at all. This article proposes a solution to both problems. The pro possessore terminology can only be assessed correctly if we focus the procedural position of the possessor, especially in the realm of the hereditatis petitio. The new terminology (titulus) is a mere consequence of the fact, that the burden of prove is assigned according to the ,title‘ of possession indicated by the possessor, not by the real (and possibly unprovable) cause.
Scriptores Iuris Romani1): Zu Schiavones Edition der römischen Rechtsschriftsteller und ihrem ersten Band Quintus Mucius Scaevola2)
Authors: Stagl Jakob Fortunat
Published: June 2021

Scriptores Iuris Romani. On Schiavone’s Project of Roman Legal Writers and their first volume on Quintus Mucius Scaevola. Scriptores Iuris Romani is a new edition of the works of the Roman jurists, comparable to that of any other author of Antiquity. Under the stewardship of A. Schiavone, this new edition undertakes to replace Mommsen’s edition of the Digest and Lenel’s ‘Palingenesia Iuris Civilis’. Due to its basis in the ‘approccio biografico’, and also due to a naive attitude towards the problems of the textual tradition – which becomes obvious in the editorial choices made by E. Stolfi, who is in charge of this volume on Mucius –, the edition of Mucius’ Opera is not as reliable as it should be. The whole enterprise must be considered an important achievement of scholarship on Mucius, but will neither replace Mommsen nor Lenel.

Rodriguez, C, Harty, PS, Stratton, MT, Siedler, MR, Smith, RW, Johnson, BA, Dellinger, JR, Williams, AD, White, SJ, Benavides, ML, and Tinsley, GM. Comparison of indirect calorimetry and common prediction equations for evaluating changes in resting metabolic rate induced by resistance training and a hypercaloric diet. J Strength Cond Res 36(11): 3093–3104, 2022—The ability to accurately identify resting metabolic rate (RMR) changes over time allows practitioners to prescribe appropriate adjustments to nutritional intake. However, there is a lack of data concerning the longitudinal utility of commonly used RMR prediction equations. The purpose of this study was to evaluate the validity of several commonly used prediction equations to track RMR changes during a hypercaloric nutritional intervention and supervised resistance exercise training program. Twenty resistance-trained men completed the study. The protocol lasted 6 weeks, and subjects underwent RMR assessments by indirect calorimetry (IC) preintervention and postintervention to obtain reference values. Existing RMR prediction equations based on body mass (BM) or dual-energy X-ray absorptiometry fat-free mass (FFM) were also evaluated. Equivalence testing was used to evaluate whether each prediction equation demonstrated equivalence with IC. Null hypothesis significance testing was also performed, and Bland-Altman analysis was used alongside linear regression to assess the degree of proportional bias. Body mass and FFM increased by 3.6 ± 1.7 kg and 2.4 ± 1.6 kg, respectively. Indirect calorimetry RMR increased by 165 ± 97 kcal·d−1, and RMR:FFM increased by 5.6 ± 5.2%. All prediction equations underestimated mean RMR changes relative to IC, with magnitudes ranging from 75 to 155 kcal·d−1, while also displaying unacceptable levels of negative proportional bias. In addition, no equation demonstrated equivalence with IC. Common RMR prediction equations based on BM or FFM did not fully detect the increase in RMR observed with resistance training plus a hypercaloric diet. Overall, the evaluated prediction equations are unsuitable for estimating RMR changes in the context of this study.

Hibbert, JE, Klawiter, DP, Schubert, MM, Nessler, JA, and Asakawa, DS. Strength, cardiovascular fitness, and blood lipid measures in law enforcement personnel after a 12-week health promotion program. J Strength Cond Res 36(11): 3105–3112, 2022—Law enforcement personnel often have high rates of cardiovascular disease and injury. Health promotion programs have been found to successfully encourage behavior change among law enforcement personnel, but these programs can often be intensive and expensive. Thus, the purpose of this study was to examine the efficacy of a health promotion program on body composition, metabolic health, muscle strength, and cardiovascular endurance in law enforcement personnel. Active duty officers from a local law enforcement agency were invited to participate in a 12-week health promotion program that included activity tracking and exercise and nutrition education. Eighteen subjects underwent measurements of body composition, V̇o
2max through treadmill test, knee extensor strength, and blood lipids. An a priori alpha level for significance was set at 0.05, and comparisons were assessed using paired t-tests. Overall, subjects improved blood lipid levels evidenced by movement of mean values toward established healthy ranges. Although 8 subjects improved their V̇o
2max (range: 1.3–30% change), there was large variability and no statistically significant differences in measures of V̇o
2max (pre: 38.48 ± 5.86 ml·kg·min−1; post: 39.27 ± 5.26 ml·kg·min−1), body composition (pre: 26.52 ± 8.02% body fat; post: 26.44 ± 7.45% body fat), and strength normalized to body mass (isometric pre: 1.45 ± 0.45; post: 1.08 ± 0.36). Although no significant changes were noted, promising trends in these data suggest that health promotion programs with a modified focus may lead to positive changes in overall health.

Published: June 2021

Prediction of the future health state of civil structures allows maintenance agencies to undertake timely repair and replacement activities. Appropriate conduct of maintenance actions ensures accident-free operation of the transport network. Precise estimation of remaining useful life of civil structures is achievable through the availability of the degradation history, selection of appropriate degradation models, and efficient prognostic algorithms. In the reported research work, the variation in modal energy due to progressive degradation of the structure is used as a degradation quantification feature. Then, a sequential Monte Carlo–based particle filter (PF)–based scheme is reformulated to undertake bridge health prognosis of an aging in-service concrete bridge situated in a harbor area, using historical nondestructive testing data. A microelectromechanical systems–based accelerometer sensors are installed at different bridge segments to record vibration data. The historical database of the degradation feature is segmented into training and validation regions. The particle filter algorithm ultimately predicts the posterior probability density function of the degradation quantification feature for the next time instant(s). The promising prognostic results highlight the efficacy of the proposed scheme.

Published: June 2021

Inferior vena cava (IVC) filters have been widely used to prevent pulmonary emboli in patients with venous thromboembolism. Here we report a rare case of complete pericardial tamponade with severe mitral and tricuspid valve regurgitation due to a fractured IVC filter. A 38-year-old male came to our emergency department with a 19-day history of progressive chest tightness. Chest x-ray revealed a tethering catheter fractured at the level of the junction of the superior vena cava and the right atrium. We performed open surgery and discovered that a steel wire had punctured the atrioventricular septum, the mitral valve, and finally the posterior wall of the left ventricle. The patient recovered quite well and was discharged after 1 week.
Adult Obstructive Cor Triatriatum with Severe Mitral Regurgitation: A Case Report
Authors: Nakajima Tomomi , Van Hung Dung , Hiramatsu Yuji
Published: June 2021

Adult cor triatriatum sinister associated with severe mitral regurgitation is extremely rare. As these obstructive cor triatriatum feature hemodynamics that mimic mitral stenosis, a pressure load is theoretically generated only on the left atrial proximal chamber, and therefore the left ventricle is less likely to suffer volume loading. Here, we report a surgical case with such rare hemodynamics. A 22-year-old man with obstructive cor triatriatum and severe mitral regurgitation received an anomalous membrane excision and mitral annuloplasty. An abnormal membrane with an orifice 7 mm in size was completely resected while a grossly dilated mitral annulus was repaired via annuloplasty ring. Mitral regurgitation was controlled well, and the postoperative course was uneventful. Even with obstructive cor triatriatum, severe mitral annular dilatation and subsequent left ventricular dilatation may occur, causing the progressive heart failure encountered in this case.

Published: June 2021

Mature pods of Leucaena leucocephala (Lam.) de Wit were utilized as raw material for nanocrystalline cellulose (NCC) production. NCC’s isolation begins with L. leucocephala fiber’s alkaline treatment with sodium hydroxide, followed by bleaching treatment at three different percentages (3%, 5%, and 7%) of sodium hypochlorite. Acid hydrolysis was then conducted to obtain NCC, which was comprehensively characterized in terms of morphology, chemical functional groups, whiteness index, and crystallinity. Fourier-transform infrared spectroscopy (FTIR) and chemical composition results showed that alkali treatment (NaOH) and bleaching (3%, 5%, and 7% of sodium hypochlorite, NaClO) were effective in the removal of lignin and hemicellulose. The variation of sodium hypochlorite concentration affected physical and structural characteristics of the NCC produced, which exhibited a rod-shaped structure with diameters ranging from 17 to 49 nm. These observations provide insight into the potential utilization of L. leucocephala as raw material for preparing nanocellulose, which may address problems of the underutilized mature pods.

This study investigates the factors that influence students in choosing a career path in accounting. The decision to choose a career path needs to be detected early because it has an impact on future professional performance which determines both the individual’s social position, style and standard of living, and life satisfaction. This study examines the factors that influence the career paths of accounting students through the social cognitive career theory. Based on this theory, the relationship between career path and driving factors such as intrinsic motivation, extrinsic motivation, third party influence, career exposure, is identified. The online survey was conducted on 333 respondents. Through regression analysis, this study found that intrinsic motivation, extrinsic motivation and career exposure have a positive effect while third parties influences do not have a significant value on career paths. These findings could be useful for policy makers and higher education institutions to provide a more supportive environment that will foster interest among accounting students to be motivated in choosing career paths in accounting.
“Halal” Abortion in Perspective Common Law system,Civil Law System and Ius Constituendum : Towards Legality and Safety
Authors: Atmadja Sardjana
Published: June 2021

Background: To safe services in hygienic conditions must be made widely available and affordable, so that the stigma associated with providing and obtaining abortions can lessen and safe services can become normal and accepted, abortion is broadly legal, widely available and safe in Indonesia.Objective: The purpose of this article to discuss ius constituendum on abortion in Indonesia from criminal law perspective between Common Law System and Civil Law System.In Indonesia Ius Contituendum on abortion  is not directed to legalization of abortion as carried out both in Netherland and USA but tends to be harmonized with therapeutic abortion concept both medical and psychiatric fields.Material and Method: Systematic review of studies evaluating the prevalence of unsafe abortion in Indonesia.Results: The public health tragedy caused by unsafe abortion is all the more so because it is largely preventable, by improving the quality and availability of post abortion care, by making abortion legal and increasing access to safe services, and—because almost every abortion is preceded by an unintended pregnancy—by expanding access to contraceptive information and services. Restrictive laws have much less impact on stopping women from ending an unwanted pregnancy than on forcing those who are determined to do so to seek out clandestine means. Ironically, the abortion laws governing of Indonesia  is holdovers from the colonial era.Conclutions:  “Halal” abortion is making a significant contribution toward reducing the need for abortion altogether and the likelihood of unsafe abortion by bringing down the rates of unintended pregnancy. This is also helping to reduce complications of unsafe abortion through its support for programs to increase access to and improve post abortion care. This includes not only treatment for septic or incomplete abortion, but also essential post abortion.Keywords: “Halal” abortion, the public health tragedy, unintended pregnancy Common law system,Civil law system and Ius Constituendum.
Classification of periodic transformations of an orientable surface of genus two
Authors: Baranov Denis A. , Pochinka Olga V.
Published: June 2021

Abstract. In this paper, we find all admissible topological conjugacy classes of periodic transformations of a two-dimensional surface of genus two. It is proved that there are exactly seventeen pairwise topologically non-conjugate orientation-preserving periodic pretzel transformations. The implementation of all classes by lifting the full characteristics of mappings from a modular surface to a surface of genus two is also presented. The classification results are based on Nielsen’s theory of periodic surface transformations, according to which the topological conjugacy class of any such homeomorphism is completely determined by its characteristic. The complete characteristic carries information about the genus of the modular surface, the ramified bearing surface, the periods of the ramification points and the turns around them. The necessary and sufficient conditions for the admissibility of the complete characteristic are described by Nielsen and for any surface they give a finite number of admissible collections. For surfaces of a small genus, one can compile a complete list of admissible characteristics, which was done by the authors of the work for a surface of genus 2.
Physical activity in the context of the COVID-19 pandemic: Research profiling and mapping
Authors: Tomanek Mateusz , Lis Andrzej
Published: June 2021

Background and Study Aim: The aim of the study is to profile and map the scientific output in research on physical activity in the COVID-19 context. The study makes an attempt to response to the three following questions: (1) What are the leading contributors (countries, research institutions, authors and source titles) to research production in the field? (2) What are the core references? (3) What are the leading thematic areas / research fronts?

Material and Methods: We used the Scopus database as a source of bibliometric data for the research sampling process and employed a combination of bibliometric methods, including research profiling and selected science mapping methods, i.e. co-word analysis and direct citation analysis, in order to achieve the aim of the study and provide responses to the study questions. Science mapping processes were supported with VOSviewer software.

Results: Research profiling indicates that the main contributors to scientific output on physical activity in the COVID-19 context are scholars and research institutions from countries, which have been heavily affected by the pandemic such as: the United States, the United Kingdom, Italy, Spain, Brazil. Certainly, the reports from China, which was the first nation to suffer from COVID-19 and associated epidemic restrictions, constitute an important input, too. The core references in research on physical activity in the COVID-19 context may be grouped into three categories aimed at: (1) investigating the consequences of pandemic restrictions on physical activity, (2) analysing the outcomes of physical activity for other variables, and (3) providing recommendations for practising home-based physical activity during COVID-19 confinement. Science mapping of the research field conceptual structure indicates the following thematic areas / research fronts in research on physical activity in the COVID-19 context: (1) ‘pandemic and its outcomes’, (2) ‘physical activity during self-isolation’, (3) ‘health behaviour’, (4) ‘food habits’, (5) ‘mental health’, (6) ‘adults and the pandemic’.

Conclusions: The study contributes to development of physical activity theory by profiling and mapping research conducted in the context of the COVID-19 pandemic. Through mapping the scientific output, the paper points out the leading contributors and core references, and makes an attempt to identify leading thematic areas / research fronts. Discovering the main signposts may be useful for all the researchers planning and designing research within the field. Moreover, mapping research fronts indicates them the topics attracting attention of the academia and potential research gaps.

Authors: Soylu Yusuf
Published: June 2021

Background and Study Aim. A global pandemic affected by COVID-19 resulted in restrictions to daily routines, including recreation activities, social skills, and academic and health quality of college students. This study aimed to evaluate the psychophysiological effect of coronavirus quarantine on physical activity and its’ relationship between sleep quality, mood states and musculoskeletal pain in college students.

Material and Methods. A total of 392 (male = 150; female = 242; age = 22.9±5.5) college students completed an online survey. The International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Brunel Mood Scale, the Pittsburgh Sleep Quality Index (PSQI) and the Visual Analogue Scale for musculoskeletal pain (MSP) were used in this study.

Results. Total physical activity significantly correlation with PSQI (p < 0.05, r = -.103), fatigue (p < 0.01, r = -.344), depression (p < 0.01, r = -.258), angry (p < 0.01, r = -.210), vigour (p < 0.01, r = -.344), neck and shoulder, upper and lower back (p < 0.01, r = -.225), neck and shoulder correlation (p < 0.01, r = -.230), upper and lower back (p < 0.01, r = -.209). Furthermore, a positive correlation was shown between PSQI and negative moods and a negative correlation with positive mood.

Background and Study Aim. It is widely used a paradigm about the interdependence between the academic and sport achievements of students. The aim of this research was to create a model for studying relationships between academic and sport achievements of the sports and physical culture university students.
Material and Methods. Totally 259 (168 male and 91 female) bachelor students of 18–23 years old studied Physical Culture and Sports were involved into the investigation. All the students were good healthy, and they participated in the sport training and competitions, according the common program. Interdependence between the semester control scores and scores of the sport achievements were studied in the frames of correlation models of parameter and non-parameter statistics. Distribution of scores was studied using Kolmogorov – Smirnov method. One-way ANOVA for repeated measures was used to determine differences between students’ scores and educational disciplines’ scores.
Results. Almost non-significant weak interdependence between results of the semester control and sport achievements was noticed (р>0.05, 0.174≤rs≤0.284). There were no statistically significant and tight correlation between semester control scores of educational disciplines and corresponding sport achievements scores (|rs|≤0.376). Contrary, in 73% of educational disciplines pairs the semester control scores showed significant and tight correlation (p<0.001, 0.385≤r≤0.895).
Conclusions. A well-known paradigm about significant relationship between academic and sport achievements of students was not confirmed with the results of this research and should be studied more profoundly.

Red color coverage (RCC) is a commercial trait developed and refined to improve the appearance of many ornamental fish commodities. In neon tetra, the status of variation of RCC is not yet investigated or reported. This study aimed to analyze the RCC variation of cultured neon tetra as a basis for breeding strategies. A total of 900 neon tetras (standard length, SL, of 2.29 ± 0.16 cm) were collected from Bojongsari, Curug, and Pondok Petir fish farms located in Depok Districts, West Java. All fish were relocated and reared in a fish farm specialized in culturing neon tetra for two weeks using nine aquariums with photoperiod set up of 12 hours bright and 12 hours dark. The RCC traits were determined according to the percentages of RCC length (%LRCC), RCC width (%WRCC), and RCC area (%ARCC) and quantified using the digital image method. The result showed that the RCC varied by sex, size, and original location (P<0.05) in a low coefficient of variation (1.89%-11.41%). The RCC values in the male group were higher than that of females based on %LRCC and %ARCC parameters (P<0.05). Males had the highest %LRCC at size LXL, which was correlated with SL (r 0.25, P<0.1), of females at M size. The %LRCC values of the neon tetra population from the Bojongsari farm were higher than those from the other locations. Based on these findings, breeding strategies of the RCC traits should consider sex, size, and population (farm location) variations. Specifically for neon tetra, this strategy should be based on selecting the SL or %LRCC parameter of M for females and LXL for males.
