Física no corpo humano: uma abordagem temática no ensino do eletromagnetismo
Authors: Anjos Vinicius , Costa Rita , Pinho Katia , Sutil Noemi
Published: October 2022

Em um cenário de controvérsias sobre composições curriculares na Educação em Ciências, evidenciam-se as abordagens temáticas e suas potencialidades concernentes à vinculação a aspectos contextuais subjacentes à ação educativa e à inter-relação entre as áreas de conhecimento. Pertinente a esse panorama, neste trabalho, analisou-se as percepções e relações estabelecidas por estudantes em abordagem temática, envolvendo material e atividades educacionais sobre o corpo humano em associação com o eletromagnetismo. Nesta pesquisa, concatenaram-se aspectos qualitativos e quantitativos, agregando a participação de discentes do 3º ano do Ensino Médio de uma instituição pública da cidade de Curitiba, no estado do Paraná, com dados constituídos por meio de questionários. As proposições de interpretações envolveram pressupostos de Análise de Conteúdo e estatística descritiva e abrangeram dois eixos: percepções sobre as composições curriculares e a aprendizagem, e as relações envolvendo conteúdos de Física associados ao corpo humano. Através dos dados levantados na intervenção em sala de aula, indícios de motivação e correlação com aspectos de aprendizagem foram evidenciados. Averiguou-se, ainda, a vinculação entre conteúdos de Física e de outras áreas de conhecimentos envolvendo a temática. Cabe salientar nesse contexto a viabilidade de abordagens temáticas para o Ensino Médio no que se refere às potencialidades de aprendizagem e de atribuição de sentido e significado às composições curriculares.
A temática “alisamento capilar” como proposta didática para o ensino de conceitos bioquímicos
Authors: Silva Lorena , Sudati Jéssie
Published: October 2022

Considerando a importância de conhecimentos sobre ciência e como eles auxiliam para uma participação ativa e responsável na sociedade atual, o presente estudo objetivou verificar o conhecimento prévio e posterior à proposta didática sobre o tema cabelo, avaliando a compreensão de conceitos relacionados às proteínas, aminoácidos e reações de oxirredução. Participaram desta pesquisa 27 acadêmicos do 5º semestre do curso de Licenciatura em Ciências da Natureza, a proposta didática foi aplicada com o uso de aula expositiva e experimento demonstrativo, e avaliada por meio de questionário prévio e posterior à proposta. No resultado deste estudo, detectou-se que os acadêmicos apresentaram dificuldades com os conceitos específicos de proteínas, o que foi demonstrado pela pouca clareza no desenvolvimento das respostas. Porém, quando questionados através de conceitos químicos relacionados ao cotidiano obteve-se resultados satisfatórios. Por fim, parte deste trabalho corrobora com a eficácia de atividades temáticas aliadas às questões do cotidiano, confirmando dados já presentes na literatura. Porém, mais estudos são necessários para suprir a demanda no entendimento de conceitos científicos de bioquímica, já que, neste contexto, a presente proposta não demonstrou eficácia em sua totalidade.

Syndicalisme maritime. Organisations et mobilisations des marins de commerce en France, 19e-21e siècles
Authors: Viaud Ronan
Published: October 2022

Professions réglementées depuis la fin du 17e siècle, les marins de commerce ne restent pas à l’écart des syndicats à partir des années 1870. Le réformisme des premières années laisse place à un recours massif à la grève locale ou nationale et à l’adhésion à la Confédération générale du travail. Jusqu’à la moitié du 20e siècle, l’action syndicale se déroule dans un cadre strictement national avec, face aux marins, l’État et les armateurs, très souvent alliés. Aux avancées sociales succèdent des défaites, accentuées par l’extrême fragmentation qui caractérise le paysage syndical. À partir de 1950, le pluralisme syndical s’impose durablement. Une autre échelle de lutte apparaît, mondiale, avec la réduction de la flotte marchande française au lendemain des décolonisations, et le développement de navires sous pavillons de complaisance. La nécessité d’organisations syndicales transnationales pour l’amélioration des conditions de travail, de sécurité et d’emploi des marins sans distinction de nationalité devient criante et reste d’actualité.
Marins, dockers et autres au sein de la Fédération internationale des travailleurs des transports (ITF) au début du 21 siècle
Authors: Crochemore Kevin
Published: October 2022

Forte des succès de sa lutte contre les pavillons de complaisance, l’ITF s’est dotée d’une équipe de permanents importante qui lui permet de déployer des stratégies standardisées alliant communication percutante et coordination entre les sections professionnelles. Toutefois, il apparaît que les identités professionnelles et les enjeux régionaux restent trop marqués pour susciter une réelle cohésion. La bureaucratisation des appareils syndicaux nourrit une incompréhension réelle des intérêts et des enjeux de la base comme de la démocratie syndicale. L’analyse de cette stratégie permet de réinterroger les voies du syndicalisme comme outil de contre-pouvoir des travailleurs.
Salaires et embauches des marins au 21e siècle. La place des pays d’Europe centrale et orientale
Authors: Le Marchand Arnaud
Published: October 2022

Au milieu du 20e siècle le travail maritime s’effectuait sur des bases nationales et protégées, alors qu’à partir du développement des pavillons de complaisance dans les années 1970, puis avec les progrès du néolibéralisme dans les années 1990, un modèle de travail globalisé s’est développé dans la marine de commerce. La transition des économies socialistes de l’Est européen vers l’économie de marché, puis l’élargissement de l’Union européenne, ont amené de nouveaux marins sur ce marché. Cette situation a incité les organisations syndicales d’Europe de l’Ouest à se rapprocher du syndicalisme transnational, tandis qu’employeurs et syndicats des pays d’Europe centrale et orientale (PECO) devaient acquérir la pratique de la négociation collective. Les salaires des marins en Europe ont convergé, alors qu’ils continuaient de diverger dans l’industrie à terre.
« Tout changer pour que rien ne change ? » : le temps long de la Françafrique
Authors: Borrel Thomas , Deltombe Thomas
Published: October 2022

Thomas Borrel, membre de l’association Survie, et Thomas Deltombe, éditeur, sont chercheurs indépendants et co-auteurs (avec Amzat Boukari-Yabara et Benoît Collombat) de l’Empire qui ne veut pas mourir. Une histoire de la Françafrique1, paru au Seuil en octobre 2021. Cette somme collective de près de 1000 pages offre une synthèse inédite sur l’histoire d’un système de domination dont l’étude reste marginale dans le monde académique. Envisagées dans le temps long, ces relations néocoloniales témoignent, selon la thèse défendue par les auteurs, d’une étonnante capacité à s’adapter pour perdurer, en dépit des proclamations de rupture ou des apparences de délitement.
En busca de la Ciudad Penitenciaria. Metáfora y materializaciones en los proyectos de reforma carcelaria del Estado Novo (Rio de Janeiro, 1937-1945)
Authors: González Alvo Luis
Published: October 2022

En 1937 se publicó un proyecto de reforma
penitenciaria para la capital de Brasil, titulado Cidade Penitenciária do Rio de Janeiro.
Desde el punto de vista arquitectónico, la “ciudad” no planteaba
grandes diferencias con otras prisiones de la época ni se presentaba
como una urbanización. La propuesta de su autor, el arquitecto
Adelardo Caiuby, recogía su experiencia como creador del Leprosário
Modelo de São Paulo (1918) cuya idea principal consistía en que los
enfermos, recluidos por mucho tiempo en el hospital, llevaran una vida
semejante a la que tenían fuera del aislamiento. Esa idea – en
teoría – fue la que Caiuby intentó trasladar al ámbito penitenciario,
aunque finalmente lo hizo con un diseño arquitectónico alejado. En
este trabajo intentaremos adentrarnos en los significados de la
metáfora de ciudad que algunos agentes estatales creyeron apropiada
para resolver los problemas carcelarios. ¿Cómo eran las condiciones de
las penitenciarías del distrito federal en 1930? ¿Quiénes fueron los
encargados de buscar soluciones? ¿Qué experiencias tenían? ¿Cuál era
la propuesta concreta de funcionamiento para esa ciudad? ¿En qué
difería de las demás cárceles existentes? Son algunas de las preguntas
que guían este trabajo.
Mecánicas del encuentro: arpones híbridos de las costas de Atacama
Authors: Ballester Benjamín
Published: October 2022

Aquellos objetos que en apariencia fingen ser
simples y banales, suelen tener profundidades insospechadas, pues
fuera de su función más evidente logran ocultar numerosos escondrijos,
intersticios y secretos. Este es el caso del arpón de hierro de
tiempos de los siglos XVI al XIX de la costa del desierto de Atacama
en el norte de Chile. Un sofisticado objeto ensamblado de múltiples
partes apenas estudiado y jamás puesto en debate, cuya singularidad es
poseer un diseño precolombino junto a materiales europeos. El
siguiente escrito revela un desconocido hallazgo depositado en el
British Museum de Londres, desde el cual se plantea una reflexión
acerca del rol de los arpones híbridos como una mecánica para resolver
las tensiones técnicas y culturales producidas por el encuentro entre
residentes nativos y forasteros europeos en un escenario litoral.
Capitalismo, mecanicas y operaciones balleneras de la factoría flotante Tioga en el Pacífico Suroriental (1911-1913)
Authors: Quiroz Daniel
Published: October 2022

La caza moderna de ballenas, originada en el
norte de Noruega, se extenderá por todos los océanos del mundo en el
siglo XX, especialmente después de la Segunda Guerra Mundial. La
mecánica ballenera tiene dos etapas bien definidas: la persecución y
muerte de los cetáceos y el faenamiento de sus carcasas tanto en
plantas costeras como en buque factorías o fábricas flotantes. En este
trabajo nos interesa mostrar la participación de uno de los primeros
buques factoría que navegó bajo bandera chilena en esta mecánica
ballenera. Se trata del TIOGA, barco construido en Copenhague, en
1890, y adquirido en 1910 para ser usado como factoría flotante,
después de ser convertido en los astilleros Framnæs (Sandefjord,
Noruega) por una sociedad ballenera con capitales noruegos que operaba
desde Corral, Chile. El TIOGA estuvo involucrado en operaciones
balleneras menos de dos años, desde su llegada a Chile, en marzo de
1911, hasta el momento de su naufragio en aguas antárticas, en febrero
de 1913. Este trabajo busca documentar la participación del buque en
dichas operaciones, integrando toda la información de contexto
necesaria para apreciarla en toda su magnitud y relevancia.El
buque factoría representa la extensión de un negocio ballenero
limitado por la necesidad de procesar de manera rápida los cetáceos
capturados y obtener un aceite de mejor calidad. Sin embargo, el
riesgo de operar una factoría flotante, lejos de casa, era bastante
grande, sobre todo en la primera década (1904-1914) desde la
conversión del ADMIRALEN, el diseño dominante de los buques factoría
iniciales.
El imperio del Gaviotín Chico. Política y naturalezas en el litoral de Atacama
Authors: Richard Nicolas , Hernández V. Consuelo
Published: October 2022

El caso del gaviotín chico (sternula lorata) y del megapuerto de Mejillones, inaugurado en 2002 (Antofagasta, Chile), constituyen un ejemplo paradigmático, simple y desconcertante a la vez, de las nuevas formas de gobernanza de la naturaleza que estructuran los paisajes contemporáneos del desierto de Atacama. El artículo retrasa la historia reciente del complejo portuario Mejillones y de sus ocho centrales térmicas a carbón y se detiene en la estrategia de conservación del gaviotín chico, principal vehículo de mitigación ambiental implementado por las principales empresas del Puerto y por el Municipio. Se estudia el proceso de construcción social del gaviotín chico desde el punto de vista de su relación a los otros habitantes humanos y no-humanos de la bahía de Mejillones. Así, mientras los nidos de gaviotín chico se multiplican en las áreas de conservación, todo a su alrededor ha sido declarado Zona de Sacrificio Ambiental. El caso del gaviotín chico constituye un archivo inesperado y una crónica posible sobre los últimos veinte años del litoral del desierto de Atacama: aquí, en la Bahía de Mejillones, donde anida del gaviotín chico, donde los perros cazan mar adentro y los jotes duermen en centrales a carbón, no rigen más las leyes de la naturaleza, porque hay otras naturalezas en formación.
“Somos una misma historia”: la militancia musical de Inti-Illimani en su exilio italiano
Authors: Fazio Luciana , Fazio Vargas Daniela
Published: October 2022

En este trabajo nos centraremos en un caso de
circulación representativo del global turn: el exilio en Italia del grupo
chileno Inti-Illimani. A parte de su gira musical, el grupo también se
encontraba en Italia por una motivación política: promocionar al
gobierno de la Unidad Popular liderado por Salvador Allende. Esta
motivación se verá truncada por el golpe de estado a manos de la junta
militar encabezada por Augusto Pinochet. Así, lo que había comenzado
como un viaje de pocos meses, se convertirá en un exilio de varios
años en el país europeo. La militancia musical hará cercano lo
distante, dando a conocer en Italia lo que sucedía en Chile,
contribuyendo así al desarrollo de redes de solidaridad. Los
italianos, por su parte, se apropiarán de estas canciones para
expresar sus anhelos y preocupaciones, lo que influirá en el quehacer
político y social italiano, así como también en las formas mismas de
hacer música. A partir de un rastreo de prensa y de un análisis de los
álbumes publicados en el exilio entre 1973-1978 se mostrará cómo la
música es capaz de conectar realidades políticas diferentes, pero de
cierta manera cercanas, propias de un mundo cada vez más
interconectado.
Return Migration of the Greeks from the Former Soviet Union. Reflections on the Diasporic Logics of Exclusion and Belonging
Authors: Kaurinkoski Kira
Published: October 2022

The question of the “return” of the Greeks from the former Soviet Union stems from the conception of the Greek nation, but it was also motivated by geopolitical, economic, and demographic considerations. In Greece, these migrants have endured professional marginalisation and social and cultural divisions. The establishment of migrants’ associations and the formation of reverse diaspora namely at the edge of big cities are the visible consequences of this “return”. This article discusses the logics of belonging and differentiation within the migrant group, and between migrants and the natives. It also examines Greek repatriation policy vis-à-vis its’ diaspora, and the scientific, official, and informal terminology used to address this specific phenomenon of “return migration”. How have the Soviet Greeks been perceived and received in Greece, and how do they identify themselves and others? What are the new identities that are created by the migration experience? The article is based on field research and interviews conducted by the author with Greeks from the former Soviet Union, representatives of migrants’ associations, and authorities in Ukraine, Greece, and Cyprus between 2001 and 2015.
Myocardial Invasion of Squamous Cell Lung Carcinoma Presenting as STEMI
Authors: Anjum Ibrar , Eajaz Farwa , Gaffar Moeed , Ling Julie
Published: October 2022

Myocardial invasion by a neoplasm is a rare occurrence that can present identical signs and symptoms of acute coronary artery disease. We report a case of a 53-year-old man diagnosed with squamous cell lung carcinoma who presented with chest pain and ST-segment elevation on an electrocardiogram. He underwent emergent coronary angiography, which ruled out coronary artery obstruction. An echocardiogram followed by magnetic resonance imaging of the heart confirmed metastatic lung mass in the left ventricular wall. The direct compression of a metastatic tumor on a myocardial wall could lead to ST-segment elevation mimicking acute coronary syndrome. Clinicians should consider metastatic myocardial tumor as a possible cause of ST-segment elevation in patients with nonobstructive coronary arteries and lung carcinoma to prevent misdiagnosis and resultant delayed treatment.
Effect of Task-Oriented Training on Hand Dexterity, Grip Strength, and Function among Institutionalized Geriatric Population
Authors: Mathews Susan , Paul Anila
Published: October 2022

Background:

The hand is the most active and important part of the upper extremity with complex functional biomechanics and anatomy. The decline in hand grip strength and dexterity with age can adversely affect functional activities. Task-oriented training (TOT) is a treatment approach focused on functional activities of daily life.

Aim:

To investigate the effect of TOT on hand dexterity, grip strength, and hand function in the geriatric population.

Subjects and Methods:

Sixteen institutionalized geriatric participants were recruited based on the inclusion and exclusion criteria and assigned to Group A experimental group (nine participants) who received TOT for 4 weeks, 3 days/week along with routine activities and Group B control group (seven participants) who were involved in routine activities only. Gross dexterity was assessed using the box and block test, fine dexterity with nine-hole peg board, hand grip strength with hand dynamometer, and hand function with the Michigan hand outcome questionnaire. The statistical analysis with Student's t-test was performed using the SPSS software. The significance level kept as P ≤ 0.05.

Results:

The analysis expressed significant improvement in gross and fine hand dexterity and grip strength among the experimental group. The hand function did not reveal a statistically significant change.

Conclusion:

A 4-week TOT program is an effective measure to improve gross and fine dexterity, and muscle grip strength in the geriatric population. For improvement in hand function, a longer training may be required.
Parkinsonism Secondary to Iatrogenic Hypoparathyroidism
Authors: Thulini Madubashini Liyana Arachchige Dona , Asgiriyage Senevirathne Sithira A. , Shehan Silva Fransisco Hettige Dhanushka
Published: October 2022

Parkinsonism is a clinical syndrome characterized by bradykinesia, rigidity, and tremor. Many causes have been identified for secondary parkinsonism. Among them, hypocalcemia due to hypoparathyroidism is one of the rarer causes. Here, we emphasized a patient presented with reversible secondary parkinsonism caused by hypocalcemia due to iatrogenic hypoparathyroidism following thyroidectomy. A 56-year-old female diagnosed with hypothyroidism and parkinsonism was admitted following a lower respiratory tract infection. She had undergone a total thyroidectomy 10 years ago, following which there were intermittent episodes of hypocalcemia. The patient was found to have hypocalcemia, hypophosphatemia, and low parathyroid hormone level. The noncontrast computed tomography of the brain showed diffuse brain calcification with a predilection to basal ganglia. Her diagnosis was refined as parkinsonism due to cerebral calcification secondary to iatrogenic hypoparathyroidism. This case emphasized the importance of evaluating treatable secondary causes of parkinsonism at diagnosis.
Women's Experiences with Maternity Care in Public Health Facilities of Assam, India
Authors: Rajbangshi Preety R. , Srivastava Aradhana , Nambiar Devaki
Published: October 2022

India is committed to Sustainable Development Goal 3 of reducing the national maternal mortality ratio to <70/100,000 live births by 2030. This article describes women's experiences of maternity care in public health facilities in three districts of the north-eastern Indian state of Assam. Fourteen focus-group discussions were carried out among 149 married women aged 18–45 years belonging to different ethnic communities. Data were analyzed using a grounded theory approach and organized using a framework of dimensions of maternal satisfaction. The findings suggest that access and distance were important considerations determining maternal care quality, especially in the two remote districts. Women reported inadequate infrastructure, lack of cleanliness, and poor access to medicines. Lack of prompt care was identified as an important issue, and women complained about being left unattended during labor and facing obstetric violence in the labor room. Our findings point toward the need to strengthen referral transport systems and establish maternity waiting homes in remote areas. It is important to also sensitize health providers about obstetric violence and the right of women to receive prompt and respectful maternity care.
Integration of Basic Occupational Health Services into Primary Health Care in Thailand
Authors: Siriruttanapruk Somkiat , Praekunatham Hirunwut
Published: October 2022

Background:

Informal workers are high-risk groups for getting occupational diseases. They also have difficulties in accessing occupational health services (OHSs). The Basic OHS (BOHS) program integrates BOHS activities into existing primary health care. The study aims to describe how the BOHS program has been developed and to update the situation of BOHS in Thailand.

Methods:

Four steps for the development of the program include (1) preparation, (2) model development, (3) implementation and expansion, and (4) quality assurance (QA). The program started with the study of the situation of OHS in primary care units (PCUs) and identification of the gap for OH practice among PCUs' staff. The pilot study was conducted in 19 PCUs. After that, expansion of the model and quality assurance of the services have been implemented until now.

Results:

In 2019, 84% of PCUs (8242) provided BOHS, but the number decreased to 22% (2123 PCUs) in 2020. The target groups were mainly farmers. The OHS activities include an arrangement of farmers' clinics and conducting outreach activities in the field. The latest health surveillance program for farmers reported that 40.5% of 862,585 farmers had high pesticide exposure by field-kit testing. Regarding the QA audit, 75% of PCUs were certified for basic or higher levels of BOHS standards.

Conclusions:

Integration of OHS into the PCUs is feasible, successful and replicable. Its sustainability requires policy support, continued empowerment of staff, and resource allocation.

Authors: Vaira L.A. , Lechien J.R. , Deiana G. , Salzano G. , Maglitto F. , Piombino P. , Mazzatenta A. , Boscolo-Rizzo P. , Hopkins C. , De Riu G.
Published: October 2022

Background: The purpose of this study was to compare the prevalence of olfactory dysfunction (OD) at different stages of the COVID-19 pandemic by evaluating subjects diagnosed with SARS-CoV-2 infection during the Omicron wave with psychophysical tests and comparing the results with those obtained from patients infected during the D614G, Alpha and Delta waves and with those of a control group. Methodology: The study included adult patients diagnosed with SARS-CoV-2 infection. Depending on the time of diagnosis, the subjects were divided into four study groups: D614G; Alpha, Delta and Omicron variant groups. A group of uninfected individuals was used as control. All subjects underwent psychophysical evaluation of the olfactory function with the Connecticut Chemosensory Clinical Research Center olfactory test (D614G and Alpha groups) or the extended version of the Sniffin'Sticks test (Delta, Omicron and control groups). Results: 372 cases (134 D614G group, 118 Alpha group, 32 in Delta group and 88 Omicron group) were recruited and evaluated within 10 days of infection, alongside 80 controls. Patients self-reported olfactory loss in 72.4% of cases in the D614G group, in 75.4% of cases in the Alpha group, in 65.6% of cases in the Delta group and in 18.1% in the Omicron group. Psychophysical evaluation revealed a prevalence of OD: 80.6%, 83.0%, 65.6% and 36.3% in the D614G, Alpha, Delta and Omicron group respectively. The differences between the D614G, Alpha and Delta groups were not statistically significant. The Omicron group demonstrated a significantly lower prevalence of OD than the other variants but still significantly higher than the controls. Conclusions: During the Omicron wave OD was less prevalent than during the D614G, Alpha and Delta periods. One-third of patients have reduced olfactory function on psychophysical evaluation during the Omicron wave. Our results should be considered with caution as the VOC has not been determined with certainty.
Elimination of DOC in RO concentrate from a wastewater reclamation plant: Cost comparison of different AOPs
Authors: Kim Beom Joon , Choi Joon-Young , Lee Hye-Jin , Lee Changha
Published: October 2022

Advanced oxidation processes (AOPs) have been reported as alternative ways for treating reverse osmosis (RO) concentrate which is the primary concern for water reclamation plants. AOPs are known to oxidize recalcitrant organic compounds by a highly reactive and nonselective oxidant, hydroxyl radical (OH). Researchers showed that AOPs such as the conventional Fenton, UV/H2O2, ozonation, electrochemical oxidation processes could remove organics in RO concentrate. However, comparing different AOPs has been rarely performed for the treatment of RO concentrate. In addition, the cost of these processes has not been fully explored. In this study, five different AOPs (i.e., the conventional Fenton, UV/H2O2, ozonation, anodic oxidation, and electro-Fenton processes) were evaluated for the removal of dissolved organic carbon (DOC) in RO concentrate. The operation costs for DOC removal by these AOPs were also calculated. The results indicated that the conventional Fenton and ozonation processes were the most cost-efficient among the processes tested.
Collaborative Learning: A Veritable Tool for Promoting Classroom Participation Among Pre-Service Teachers in Rural Universities in South Africa
Authors: Adebola Oyinlola Omolara , Tsotetsi Cias
Published: October 2022

The benefits of collaborative learning (CL) in teaching-learning have been well-documented. According to existing literature, it will help students and teachers learn from one another, develop good communication skills, foster a sense of community, trust and respect, and retain and apply the information in their future studies. Unfortunately, observation coupled with research shows that pre-service teachers’ participation in South Africa's rural universities is at its lowest ebb – a potential source of concern to education stakeholders given its futuristic implications in the light of CL benefits. Less pre-service teachers’ participation has been linked to cultural influence, environmental factors and students’ backgrounds and have negatively impacted students’ academic achievement. This paper seeks to typify CL as a panacea to pre-service teachers' apathy toward learning. In doing this, social constructivism theory (SCT) was adopted to underpin the study. Drawing from the principles of participatory action research, fifteen undergraduate students were randomly selected, and data was gathered with the instrumentation of semi-structured interviews and focus groups. The study revealed the think-peer-share strategy, group work strategy, micro-teaching strategy, positive feedback and encouragement, learner-centred method, and inquiry method as strategies for improving participation among pre-service teachers in rural universities. Recommendations were made in line with the findings of the study.
Friendship as a Value in Academic Ethos
Authors: Abassy Małgorzata
Published: October 2022

The aim of the research work reported here was to clarify the semantics of the notion of “friendship”. The main research question is to what extent friendship is recognised by students and teachers as a value constituting the identity of the Jagiellonian University’s (JU) academic community. From it follows another one: what role does friendship play in the value system of the academic ethos– does it have the potential to clarify or transform values enshrined in documents and recognised as enduring? This study uses qualitative data generated from the collected research material: semi-structured interviews and online surveys with closed questions, single and multiple choice. Content analysis was used to examine the interviews by identifying words, phrases and sentences related to the research tasks. The conclusions can be summarised as: 1.Friendship functions in horizontal relationships; 2. Friendship is an essential value of university ethos, realised through its other, already recognised and acknowledged, values: fair treatment, kindness, responsibility and respect for the other; 3. Friendship evolves in the system of references; 4. Friendship realised as a value of the ethos leads to a merger of the professional and the private spheres; 5. Friendship is automatically excluded when a vertical relationship appears.
Menyingkap Fungsi Sosial Perbankan Syariah Dan Pengaruhnya Terhadap Kinerja Keuangan
Authors: Sulhani Sulhani , Mughni Abdul
Published: October 2022

The social function of Islamic banking is an essential factor in the existence of Islamic banking, and research is still lacking. This study aims to analyze the trend of the social function of Islamic banking, its reporting conformity with accounting standards, and its effect on the financial performance of Islamic banking. The population of this study is Islamic Commercial Banks (ICB) registered with the Financial Services Authority (FSA) from 2014-2019. The sampling technique used purposive sampling and obtained 59 samples. The method of analysis used descriptive analysis and multiple linear regressions. The results show that fines and non-halal income still dominate the social function instrument. Social functions such as zakat, infaq, alms, and waqf tend to be low. Social reports in the form of sources and uses of zakat funds are sufficient. Reports on sources and uses of benevolent funds are also in the sufficient category, but the percentage value is lower. Internal zakat positively affects the performance of Islamic banking as measured by Return on Assets (ROA) and Operating Expenses on Operating Income (BOPO). Other variables do not affect the performance of Islamic banking as measured by ROA, BOPO, and Non-Performing Financing (NPF). This research theoretically confirms that internal zakat can encourage the growth of Islamic banking. Islamic banking must pay attention to social functions, especially zakat, an order from Islam.

Pawn gold is the flagship product of Islamic banks, and this product has low risk, is profitable, and has the potential to increase bank assets. This study aimed to show the effect of knowledge and marketing on customer interest in gold pawn products at Bank Jabar Banten Syariah (BJBS) sub-branch office Bumi Serpong Damai, South Tangerang. This research uses quantitative methods using multiple linear regression analysis using SPSS Version 23. The population of this study is customers of BJBS sub-branch office Bumi Serpong Damai who are users of savings products totaling 1,276 people. Measurement of the sample using the Slovin method obtained a total sample of 93 customers. Data was collected by distributing questionnaires to respondents using the incidental method. The results showed that knowledge did not affect customer interest. Marketing has a positive and significant effect on customer interest. Simultaneously, knowledge and marketing significantly affect customer interest, amounting to 69.5%. This research can complement existing theories and be a reference for Islamic banking in gaining customer interest in gold pawn products.

Published: October 2022

This study aims to show the problem of the credit crunch in Islamic banking in Indonesia from the perspective of Tawhidi String Relation (TSR). This research is a literature review using library data. The study results show that the main problems that trigger the emergence of a credit crunch in Islamic banking in Indonesia are natural disasters and the lack of availability of Islamic banking capital. Religious values have become a concept and a reference for every Islamic banking activity in Indonesia, which is based on the Al-Quran and Hadith. This research can be used as a reference for increasing the productivity of Islamic banking in maintaining the stability of the national economy. Practically this research can be a basis that can be applied universally in achieving benefits for all people.

The purpose of this study was to analyze the effect of performance ratios, namely capital adequacy ratio (CAR), non-performing financing (NPF), and financing to deposit ratio (FDR), on third-party funds (TPF) at Islamic commercial banks (ICB). Then, analyze the performance ratio and growth of TPF before and during the covid-19 pandemic on ICB. The method in this research uses a quantitative approach. Data collection uses secondary data in the form of documentation. The population of this study is all ICB registered with the financial services authority (FSA) for the 2019-2020 period. Sampling in this study uses purposive sampling. The data analysis technique used multiple linear regression analysis and comparison of paired samples. The results showed that partially CAR, NPF, and FDR did not affect the growth of TPF in ICB. However, CAR, NPF, and FDR simultaneously affect the growth of TPF in ICB. Then the comparison results show no difference in CAR, NPF, and FDR before and during the covid-19 pandemic. However, the growth of TPF shows a significant difference before and during the covid-19 pandemic.

Exploratory Analysis of Regional Disparities in Human Development in Cameroon
Authors:   Faculty of Economics and Management, University of Dschang, Cameroon, FEMBA Serge Decroly
Published: October 2022

The objective of this paper is to analyze the link between geographic location and the level of human development in Cameroon. To achieve that objective, we use Exploratory Spatial Data Analysis (ESDA) techniques on regional human development indices (HDI) in Cameroon from 2001 to 2014. The Moran test confirms the presence of a positive and significant global spatial autocorrelation of the regional human development indices. Thus, the values of the regional human development index in Cameroon are not randomly distributed. There is thus spatial clustering of regions with similar HDI levels. The spatial dependence of the regional HDI in Cameroon suggests cooperation and synergy of action by the regions within the framework of their competences resulting from decentralization, in order to take advantage of the spatial diffusion effects of human development. The Cameroonian government could pursue geo-targeting policies in the implementation of development programs, focusing on regions where spatial externalities would have a greater impact.

Activated carbon is widely used as an adsorbent to remove numerous pollutants from water and wastewater. The cost-effectiveness of an adsorbent depends upon its ability to be reused. This study focuses on regenerating Millettia thonningii seed pods' activated carbon (MAC) saturated with Methylene Blue (MB) using acetic acid as a regenerating solvent and exploring its potential to be reused. The effects of the variables such as, the concentration of the regenerating solvent, contact time, and volume of regenerating solvent on the regeneration process were ascertained using the Box-Behnken experimental design, which is a sub-set of Response Surface Methodology. The regeneration process was evaluated based on the desorption capacity of the active carbon. Scanning Electron Microscopy (SEM) and Fourier Transform Infrared spectroscopy (FTIR) was used to characterize the surface of the saturated active carbon before and after regeneration.  Results revealed that the concentration of the regenerating solvent had the most significant synergistic effect on the regeneration process. The optimum conditions for the maximum regeneration of the spent activated carbon within the range of the variables studied were found to be: 8M acetic acid, 100 min, and 40 mL of acetic acid. The regenerated and pristine MAC when reused to adsorb fresh MB solutions (50 ml of 10mg/L MB: 0.2g adsorbent) had an adsorption capacity of 2.1912mg/g and 2.0977mg/g for MB respectively. Hence, the regenerated carbon outperformed the pristine active carbon. It could therefore be explored further as a recyclable adsorbent for wastewater treatment.

Lasers have been utiliSed in the field of dentistry for over 40 years, but their use has been limited in the field of orthodontics. The advent of lasers with accompanying computer interfaces has made them significantly user-friendly, adding to their appeal in the orthodontic profession. Knowledge regarding the laser device's capabilities and limitations is essential to optimise patient care and to make a satisfactory investment return. For the effective and successful integration of lasers in orthodontic practice, adequate training is required, limited not only to the orthodontist but the dental assistants and auxiliaries as well. Orthodontists may safely and readily execute gingivectomy, exposure of teeth, frenectomy, circumferential supracrestal fiberotomy, ankyloglossia release and uvulopalatoplasty. The current narrative review was planned to introduce the benefits and general principles of soft tissue lasers in the field of orthodontics and recent surgical research comparing different laser-assisted surgeries against conventional scalpel surgeries.
