Published: November 2022

Objectives:

The objectives of this study were to evaluate the accuracy of the diagnosis based on the phone forwarded pelvic radiographs for developmental dysplasia of the hip (DDH) and whether to accept decisions based on phone images.

Methods:

Two hundred and eight pelvic radiographs (416 hips) performed for DDH screening were evaluated by three orthopedic surgeons on picture archiving and communication system (PACS) and re-evaluated by the same surgeons after receiving them blindly on their phones through the WhatsApp application. Phone pictures were evaluated on both portrait and landscape viewing interfaces.

Results:

Nine ossification centers (2.9%) were detected on PACS but were not noticed when evaluated on the phone due to the lower phone image quality. All dislocated and dysplastic hips were correctly diagnosed by the phone. The phone overestimated the acetabular index by about two degrees, which explains why 4.8% and 7.5% of normal hips on PACS viewers were labeled dysplastic once evaluated on phone portrait and landscape viewers, respectively. However, landscape phone viewing and smaller phone screens were associated with a higher overestimation of the acetabular index.

Conclusion:

The phone is a valuable and safe tool for diagnosing DDH from pelvic radiographs. However, a precaution should be taken in borderline cases as the phone overestimated hip angles resulting in a misdiagnosis of normal hips as dysplastic. However, we do not recommend or encourage this practice because clinical evaluation is essential in any clinical decision-making.

Textile study courses – evaluation of student performance over one complete decade
Authors: Mahltig Boris
Published: November 2022

The success of students and their performance are influenced by manifold parameters. The current study focusses especially on the correlation between study duration and the student performance. Investigated are the numbers of two textile related courses (bachelor and master) over the complete time frame of one decade. Data of more than 800 students are considered. Data evaluation is done with the final marks of the students and by using a calculated value – the student performance index PI. Especially discussed is the behavior of long-time students needing more than the double of the regular study duration. In this study only results of students are discussed which successfully finished the study course with a degree. Students leaving without a degree are not considered. For the bachelor course a correlation of their final grades with larger study duration can be determined. In contrast, for the master course nearly no influence of the study duration on the student performance is determined. A possible explanation for these different results can be discussed with the different reasons for longer study duration. For master course it is obviously the situation that the studying is combined with part-time or even full-time jobs. This combination of job and study course leads even for excellent students to prolonged study duration. With this background, for future developments a special designed part time master study course should be developed and offered for students who like the combination of a job carrier with gaining simultaneously a master degree.

Seismica, a community-run Diamond Open Access (OA) journal for seismology and earthquake science, opened for submissions in July 2022. We created Seismica to support a shift to OA publishing while pushing back against the extreme rise in the cost of OA author processing charges, and the inequities this is compounding. Seismica is run by an all-volunteer Board of 47 researchers who fulfil traditional editorial roles as well as forming functional teams to address the needs for technical design and support, copy editing, media and branding that would otherwise be covered by paid staff at a for-profit journal. We are supported by the McGill University Library (Québec, Canada), who host our website and provide several other services, so that Seismica does not have any income or financial expenditures. We report the process of developing the journal and explain how and why we made some of the major policy choices. We describe the organizational structure of the journal, and discuss future plans and challenges for the continued success and longevity of Seismica.

Contexte : Le naufrage d'un bateau d'immigration clandestine constitue un événement imprévisible, responsable d'une catastrophe de masse pouvant générer une importante caisse de résonance médiatique. Cela constitue donc une urgence médico-sociale. Objectif : Dans ce travail, nous proposons de rapporter le bilan de l'activité du service de médecine légale de Sfax (Tunisie), de décrire la procédure de gestion des catastrophes de masse liées au naufrage de bateaux d'immigrés clandestins et d'étayer les principales difficultés rencontrées. Méthodes : Il s'agit d'une étude rétrospective et descriptive portant sur tous les cas de mort par submersion suite au naufrage de bateaux d'immigration clandestine, ayant fait l'objet d'une autopsie médico-légale au service de médecine légale de l'hôpital Habib Bourguiba de Sfax, durant une période de quatre ans allant d'octobre 2017 à septembre 2021. Résultats : Durant la période d'étude, nous avons colligé 539 décès par submersion à la suite de naufrages de bateaux d'immigration clandestine. La médiane des décès était de 93 cas par an. Nous avons remarqué un déclin important du nombre de victimes en 2019 (13 victimes) puis une remontée importante en 2020 (115) et surtout en 2021 (271). Nous avons noté deux pics de fréquence pendant les mois de juin et juillet (31,4 % et 20,8 % respectivement). Les victimes étaient essentiellement de sexe masculin (67,5 %) avec un sex ratio de 2,08. Nous avons noté la présence de mineurs âgés de moins de 18 ans dans 5,8 % des cas et de femmes enceintes dans 2,4 % des cas. La majorité des victimes étaient d'origine subsaharienne (63,1 %). Nous avons noté une augmentation du nombre de victimes de l'ethnie subsaharienne les deux dernières années. Des prélèvements ont été réalisés systématiquement pour une étude génétique. Le nombre de victimes identifiées était de 146, soit 27,1 % de tous les cadavres. Conclusion : Même si des avancées importantes ont pu être réalisées, différents défis et difficultés restent à surmonter pour pouvoir apporter une réponse rapide aux familles qui vivent dans l'incertitude quant au sort de leurs proches disparus.
Geomechanical parameters in the active zone of an unsaturated tropical soil site via laboratory tests
Authors: Fernandes Jeferson , Saab Alfredo , Rocha Breno , Rodrigues Roger , Lodi Paulo , Giacheti Heraldo
Published: November 2022

The seasonal variability of geotechnical parameters in the unsaturated zone is typically neglected in the design of geotechnical works. In most of the geotechnical projects the parameters are determined only for the saturated condition. Although it is known that this condition is the most critical to soil strength and deformability, this conservative approach may neglect a possible important contribution of the unsaturated condition, resulting in an increase in the cost of the geotechnical solution. This paper presents and discusses the site characterization of the active zone of an unsaturated sandy soil profile under different suction conditions. Laboratory tests with controlled suction (retention curves, triaxial compression with bender elements and oedometer tests) were carried out on undisturbed samples collected from 1.0 to 5.0 m depth. The results show that strength and deformability parameters are strongly affected by soil suction and are less influenced by confinement stress up to 5.0 m depth. All the investigated subsoil profile shows a collapsible behavior, more pronounced closer to the ground surface and under the effect of higher suction values. The findings highlight the importance of incorporating the suction influence in the site investigation, parameter determination, and geotechnical design for more economical, reliable, and environmentally sustainable solutions.

Authors: Altunkılıç Tarık , Arı Bünyamin , Yetiş Mehmet , Kılıçaslan Nihat , İnceoğlu Feyza
Published: November 2022

Background/Aim: Hip ultrasonography (USG) is the most important diagnostic method in developmental hip dysplasia in newborns. However, a disadvantage of the ultrasonography method is that there can be measurement differences among doctors measuring the same hip. We aimed to investigate the causes and solutions of this situation. We further strived to measure the hip ultrasonography performed by different physicians using the Graf method and comparing the obtained values.

Methods: Hip USGs of newborns admitted to Malatya Turgut Ozal University Faculty of Medicine Hospital between Jan. 8, 2020 and Jan. 5,.2021 were measured and classified using the Graf method. The study type is consistent with retrospective cohort studies. Newborns aged 0-22 weeks without any additional pathology were included in the study. A radiologist and two orthopedists measured and interpreted the images separately in accordance with the Graf method. The first hip measurements (R1) were made by the radiologist (R) with the USG device, and they were classified according to alpha and beta angles; two printouts were made. The first orthopedic specialist (OS1) and the second orthopedic specialist (OS2) made their measurements with printouts. Subsequently, the results from the physicians were compared.

Results: A statistically significant difference was found between R1-OS2 (P < 0.001) and OS1-OS2 (P < 0.001) in terms of the Graf classifications. No statistically significant difference was found between R1 and OS1 in terms of the Graf classification (P = 0.562). A statistically significant difference was found between R1-OS2 (P < 0.001) and OS1-OS2 (P = 0.048) angles (alpha and beta) measurements. While R1 and OS1 measurements were compatible with each other, OS2 measurements were found to be inconsistent.

Conclusion: We think that there may be differences in angle measurements and the Graf classification among physicians who perform hip ultrasonography in newborns, and the most important way to correct this is through regular participation of physicians in subject-specific trainings.

Published: November 2022

Background: Although research has been undertaken on medicine prices, there has so far been insufficient progress in improving medicine affordability and availability for individual patients in many countries. Hypertension is a major risk factor for cardiovascular disease (CVD) such as acute myocardial infarction (AMI), stroke, heart failure and death. WHO has estimated that hypertension alone accounts for 4.4% of all disability adjusted life years that are ranged from NGN1200 to NGN4250. The aim of this study is to do a pharmacoeconomic evaluation of hypertension and hypertension comorbid with diabetes medications in selected health facilities in Jos and environs, Central Nigeria. Patients’ income per month was assessed ranging from <20,000.00 to ≥ NGN181, 000.00. The medications presented to the patients first were rotated for different patients to eliminate bias. There was a relatively higher cost of treatment in Nasarawa compared to Plateau state. The cost of treatment was highest in private facilities, higher in Faith-based institutions than the public facilities. It cost an unskilled labourer between 27 to 45 days wages to treat hypertension (catastrophic). The monthly cost of medication ranges from NGN1000 to NGN3725 cost. Results show that the monthly cost of treating hypertension ranged from NGN1000 to NGN3000 and NGN1200 to NGN4250 for comorbid cases. Prices of essential medicines used in the management of hypertension and hypertension comorbid with diabetes is quite high compared with the international reference prices. The treatment in both cases were mostly unaffordable for the threshold of an unskilled labourer and majority of the patients. Policy options towards ameliorating these catastrophic effects as the main focus of government and relevant stakeholders is hereby recommended.
On structure analysis of finitely generated abelian groups

Published: November 2022

In this paper we give an overview of the structural analysis of finitely generated abelian groups and modules. We give an overview of recent results on the structure theory of these objects in various situations, in particular in the case of torsionfree groups of infinite rank. We also mention several open problems. We also propose a method to study the structure of finitely generated abelian groups and finitely generated nilpotent groups by using some invariants of their derived series. This method provides a new framework for studying the structure of finitely generated abelian groups and finitely generated nilpotent groups.

Published: November 2022

This work aimed on the adsorption of safranin dye from wastewater using activated groundnut pods (AGP). The raw pods were collected, crushed into particle size of about 400 - 550 μm and modified in-situ with ZnCl2 to prepare AGP which was characterized using analytical technique; Fourier Transform Infra-Red (FTIR), Energy Dispersive X-ray (EDX) spectroscopy, Thermo gravimetric analyser (TGA) and Scanning Electron Microscopy (SEM). The absorbance of the dye solution was monitored at 530 nm with UV-Visible spectrophotometer. FTIR analysis showed the vibration frequency for C‒H, O‒H, C=O and C‒O stretches at 2900, 3420, 1730, and 1100 cm-1 respectively. SEM results revealed the AGP has a porous surface with heterogeneous pores which became compact after dye adsorption. EDX confirmed the presence of C, O, Zn and Cl in the adsorbent. The suitability of the pseudo-first, pseudo second and Elovich kinetic models for the sorption of safranin onto AGP was examined. The equilibrium data were subjected to Langmuir, Freundlich, Tempkin and Dubinin-Radushkevich isotherm models. Adsorption factors were optimized by Box-Behnken design using response surface methodology (RSM). The pseudo-second order kinetic model provided the best correlation and was found to be more statistically significant. Langmuir model was found to fit well based on the high values of the coefficient of regression R2 and low % standard error values. The monolayer adsorption capacity Qmax was found to be 45.45 mgg-1. Thermodynamic adsorption processes showed the spontaneous, endothermic and randomness of the systems with free energy change less than zero, enthalpy change (∆H) of 66.43 kJmol-1and entropy change (∆S) of 145.37 Jmol-1K-1. Response Surface Methodology (RSM) showed that 0.55 g was the optimum dosage with 92.50 % removal of safranin dye concentration of 200 mgL-1 at pH 10.

Authors: Aiswarya Lakshmi A.G  , Rakesh Kumar Jat  , Siju E.N
Published: November 2022

The aim of the present study was to investigate the in vitro antioxidant activity of hydroalcoholic extract of Triphala and its ecologically friendly synthesized silver nanoparticles. In the present study, we conducted an estimation of the extract using Hydrogen peroxide radical scavenging assay and superoxide radical scavenging assay to assess the antioxidant potential. The results were compared with the effect of standard ascorbic acid. Primary phytochemical screening of the plant extract showed the presence of carbohydrates, alkaloids, glycosides, flavonoids, phenolics etc. The hydroalcoholic extract and its SNPs showed a concentration-dependent activity in both methods. In the study, it was concluded that the hydroalcoholic extract of Triphala comprises pharmacologically important phytoconstituents like phenolic compounds and flavonoids which impart the potential of the extract as well as its SNPs in the modulation of oxidative stress owing to its strong antioxidant and free radical scavenging activities.

Receptors have a fundamental role to play in the birth of culture and the science of peoples. In addition to having an informative function of environmental conditions, the receptors perform an important protective and defensive activity for the living. In fact, they have the ability to make us recognize useful substances from harmful ones based on their organoleptic characteristics, color, smell, flavor, favoring the consumption of the first, preventing that of the second. They also form a second protective barrier at the level of the cell membrane by selecting the entry of unnecessary and potentially harmful substances and preventing their absorption through selective cellular channels. By means of channel proteins and ion exchange proteins (for example sodium-potassium), they maintain the optimal concentration of solutes in the cell. Finally, they guide the intra and interspecific relations between all living beings, from plants to man. We owe our existence to the reception systems. In this article we are going to examine the receptor systems describing the importance they have had in the evolution of the living and we are going to critically discuss the most recent theories proposed by quantum mechanics to explain their functioning.

Authors: Ferdinandus Marcy Saartje
Published: November 2022

Writing includes the ability to express students' opinions or be taught clearly and effectively in written form. Using audiovisual media can improve students writing skills. The purpose of this study is to find out the process and results of improving writing skills by using audiovisual media. The method used Class Action Research (CAR) with a qualitative approach. In collecting the data using observation and documentation. To analyze the success rate or percentage of student success after the teaching and learning process each cycle is done by providing the same evaluation in the form of written test questions at the end of each cycle. After the data is collected, data analysis is calculated using simple statistics that are to assess formative tests and learning completion. The result of the reduction of the data is presented in the form of a data display and then last concluded. The research procedures are planning, implementation, observation, and reflection. The results have shown the average student learning outcome was 72.33% and the number of students who had completed there was 25 children was 83.33%, and the unfinished 5 children (16.67%). This research was said to be successful if the average test score of students writing above KKM scores, which is 70, and students who score above KKM is at least 80%. At the end of Cycle 2 obtained data: the average student learning outcome was 72.33% and the number of students who had completed there was 25 children was 83.33%, and the unfinished 5 children (16.67%). So, based on data on cycle 2 of Class Action Research is said to have been successful. The findings showed that using audiovisual media could better give a  positive effect on the motivation and attention of less active students. The result of this study is that audiovisual media in the form of animated videos can improve students' writing skills in English. Learning by using audiovisual media in the form of animated videos will awaken the spirit of student learning amid the saturation of online learning.

Preserving culture can be done through the folklore that are passed down from generation to generation. The main aim of this survey is to see the challenges and opportunity for Maluku Folklore preservation. This research provides an insight on the students’ reading habit and preference, the availability of Maluku Folklore, and students’ perception on Maluku folklore. The data collected 248 responses through an online survey. The result highlighted several interesting information; 1) Despite the result show respondents perceived reading as their hobby, their preference activity shows that in their free time books are not the first choice and the culture of bedtime stories and/or being read to by parents are an uncommon practice. 2) Students rarely read Maluku Folklore unless it is an assignment from school. 3) Students believed that Maluku Folklore is not as popular and available compared to folklore from other parts of Indonesia. 4) Maluku Folklore is not readily available for students to find and consume. 5) Students prefer to read on digital and online platforms compared to the printed ones. 6) Opportunities for preservation can be done by embracing the technology and internet to tapped in to the current young people reading preferences and habit.

Authors: BURAN Abayhan , TOPDEMİR Aykut
Published: November 2022

In this study, it was aimed to determine the total antioxidant capacity and phenolic and flavonoid amounts of Lavandula officinalis (lavender), which is an aromatic plant, callus extracts. Combinations of Naphthalene Acetic Acid (NAA), Benzylaminopurine (BAP), Kinetin (KIN) and 2,4-Dichlorophenoxy Acetic Acid (2,4-D) plant growth regulators at different concentrations were used in the growth medium. The specified analyzes were carried out for the extracts obtained from the callus of plants grown in different media. The callus were extracted with water and ethanol solvents. Total phenolic amount analyzes were accomplished using the Folin-Ciocalteu method. The spectrophotometric AlCl3 method was used for the total flavonoid amount analysis and the antioxidant capacity of lavender callus extracts was measured considering the radical cation capture ability of 2,2′-azino-bis -3- ethylbenzthiazoline -6- sulphonicacid (ABTS). The highest antioxidant capacity (9.24 ± 0.14 mmol TEAC/g dry callus weight) was obtained from the callus of plants grown in medium containing 0.5 mg/L BAP + 0.5 mg/L 2,4-D combination; the highest amount of phenolic substance (35.74± 0.48 mg GAE/g dry callus weight) was obtained from the callus of plants grown in medium containing the combination of 0.5 mg/L BAP + 0.5 mg/L NAA; the highest amount of flavonoid substance (32.42 ± 0.46 mg QE/g dry callus weight) was obtained from the callus of plants grown in medium containing the combination of 0.5 mg/L BAP + 1 mg/L 2,4-D. The results are compared for the combination of plant growth regulators and the effects of the different growth medium ingredients were specified.
Taiteen osallisuus, osallisuuden taide – Tulkintoja taidelähtöisten menetelmien käytöstä koulussa
Authors: Kiilakoski Tomi , Tervahartiala Marika
Published: November 2022

Tarkastelemme artikkelissa taidelähtöisten menetelmien käyttöä peruskoulun yläluokilla. Analysoimme, millaista toimintaa taidelähtöiset menetelmät tuottavat ja miten koulu toimintaympäristönä ja tilana rajaa toimintaa, sekä kysymme, minkälaisia vaikutuksia taidelähtöisillä menetelmillä on yksilöille, ryhmille ja sukupolvisuhteille. Keskeinen käsite artikkelissa on osallisuus. Osallisuus määritellään yhdistelmäksi tunnustettua asemaa, syntyvää toimintaa ja kokemusta osallisuudesta toimintaan. Artikkeli perustuu kahdessa pääkaupunkiseudulla sijaitsevassa peruskoulussa toteutetun taidelähtöisiä menetelmiä hyödyntävän projektin etnografiseen seurantaan. Etnografia dokumentoitiin piirtäen. Analyysivaiheessa on yhdistetty visuaalista aineistoa aiemmin kerättyjen nuorten (N=8) ja ohjaajien (N=12) haastattelujen tulkintaan. Tutkimustulosten mukaan koulun olemassa oleva toimintakulttuuri vaikuttaa verrattain vahvasti siihen, miten nuoret suhtautuvat taidelähtöisten menetelmien käyttöön kouluaikanaan. Koulun vuorovaikutussuhteet, toiminnan tavat ja nuorten ryhmädynamiikka heijastuvat toimintaan. Taiteen tuottamina myönteisinä vaikutuksina analysoidaan yksilötason muutosta, ryhmäsuhteiden ja sukupolvisuhteiden muutosta sekä lyhytkestoisia instituution toiminnan muutoksia.
Toisin kokeminen ja toisin eläminen ihmisen kasvun ja sosiaalipedagogisen kasvatuksen ja ohjauksen haasteena
Authors: Kuosmanen Voitto
Published: November 2022

Ihminen ratkaisee koko elämänsä ajan jännitettä, joka rakentuu hänen omien pyrkimystensä sekä yhteisöön ja yhteiskuntaan sopeutumisen välille. Jos ihminen sopeutuu liikaa yhteisön ajattelu- ja toimintatottumuksiin, hän menettää vapautensa ja mahdollisuutensa rakentaa itse valitsemaansa elämää. Jos ihminen haluaa vapautua ajatteluaan ja toimintaansa rajoittavasta sopeuttamisesta, hänen on etsittävä ja löydettävä tie muutokseen. Jotta hän voi muuttaa elämäänsä, hänen on saatava kokemus toisin elämisestä. Kuinka toisin kokeminen ja toisin eläminen voisi olla mahdollista? Tässä tekstissä pohdin ihmisen pyrkimyksiä vapautua holhouksesta oman elämänsä eläjäksi sekä sosiaalipedagogisen kasvatuksen ja ohjauksen roolia sen mahdolliseksi tekemisessä. Toisin elämisen mahdollisuutta pohdin Jürgen Habermasin kehittämän ja Juhani Pietarisen täydentämän tiedonintressiteorian valossa.
Mitä ammattikorkeakoulun kansalaistoiminnan ja nuorisotyön koulutusohjelman lehtorin sosiaalipedagoginen asiantuntijuus voisi olla?
Authors: Anttonen Erja
Published: November 2022

Tarkastelen Humanistisen ammattikorkeakoulun kansalaistoiminnan ja nuorisotyön koulutusohjelman kontekstissa lehtorin sosiaalipedagogista asiantuntijuutta. Lähden liikkeelle kuvaamalla Humanistisen ammattikorkeakoulun, yhteisöpedagogitutkinnon ja omia lähtökohtiani. Määrittelen asiantuntijuutta, sen yhteisöllistä luonnetta ja integratiivista pedagogiikkaa. Tarkastelen tanskalaisen Bent Madsenin ja brasialaisen Paulo Freiren sosiaalipedagogista ajattelua ja antia sosiaalipedagogisen asiantuntijuuden kannalta. Lopuksi pohdin Humanistisen ammattikorkeakoulun lehtorin sosiaalipedagogisen asiantuntijuuden kehittämisen mahdollisuuksia ja teen muutamia kysymyksiä. Katsaus on vahvasti itsereflektiivinen.
