AbstractPBI Number: 7/46/PBI/2005 explained that in murÄbaá¸¥ah financing, if the bank represented the customer to purchase goods, then murÄbaá¸¥ah contract must be made after the goods became the bank's property. Meanwhile, BSI KCP Sukoharjo Kartasura carried out a murÄbaá¸¥ah contract before the goods became the bank's property. This was not in accordance with the PBI and it couldbe said that there was engineering in financing implementation. This study aimed to analyze the mechanism of murÄbaá¸¥ah financing at BSI KCP Sukoharjo Kartasura based on PBI Number: 7/46/PBI/2005 and analyze causative factors of engineering in financing. This study used qualitative field research and the Miles and Huberman method, with data collection techniques were interview with related parties and documentation. This studyconcluded that the murÄbaá¸¥ah financing mechanism in BSI KCP Sukoharjo Kartasura consists of filling out forms, BI checking, surveys, etc. The financing mechanism was generally appropriate. However, in its implementation, not all provisions have been carried out properly. BSI KCP Sukoharjo Kartasura carried out amurÄbaá¸¥ah contract before the goods became the bank's property. Then, it could be said that there was engineering in the financing implementation. The causative factors were the bank wanted to save time, minimize expenses, etc.Keywords: Financing; Mechanism; MurÄbaá¸¥ah; PBI.Â AbstrakPBI Nomor: 7/46/PBI/2005 menjelaskan bahwa dalam hal pembiayaan murÄbaá¸¥ah, apabila bank mewakilkan kepada nasabah untuk membeli barang, maka akad murÄbaá¸¥ah harus dilakukan setelah barang menjadi milik bank. Sedangkan BSI KCP Sukoharjo Kartasura melaksanakan akad murÄbaá¸¥ah sebelum barang menjadi milik bank. Hal ini tidak sesuai dengan PBI dan dapat dikatakan bahwasannya terdapat rekayasa dalam pelaksanaan pembiayaan tersebut. Penelitian ini bertujuan menganalisis mekanisme pembiayaan murÄbaá¸¥ah di BSI KCP Sukoharjo Kartasura berdasarkan PBI Nomor: 7/46/PBI/2005 dan menganalisis faktor penyebab terjadinya rekayasa dalam pembiayaan tersebut. Jenis penelitian ini menggunakan penelitian kualitatif lapangan serta metode Miles dan Huberman, dengan teknik pengumpulan data berupa wawancara pihak terkait dan dokumentasi. Hasil penelitian ini menyimpulkan bahwa mekanisme pembiayaan murÄbaá¸¥ah di BSI KCP Sukoharjo Kartasura terdiri dari pengisian form, BI checking, survei, dan lain sebagainya. Menurut PBI Nomor: 7/46/PBI/2005, secara umum mekanisme tersebut sudah sesuai. Namun, dalam implementasinya belum semua ketentuan sudah dijalankan sebagaimana mestinya. BSI KCP Sukoharjo Kartasura melaksanakan akad murÄbaá¸¥ah sebelum barang menjadi milik bank. Maka, hal ini dapat dikatakan bahwasannya terdapat rekayasa dalam pelaksanaan pembiayaan tersebut. Faktor penyebabnya yakni karena pihak bank sebisa mungkin ingin menghemat waktu, meminimalisir pengeluaran, dan lain sebagainya.Kata Kunci: Mekanisme; MurÄbaá¸¥ah; PBI; Pembiayaan.

Authors: Ramirez Barranco Rosangela , Costa Barney Valeria Atenea , Rincón Reinaldo Andres
Published: March 2022

Introducción: la prevalencia de la anemia ferropénica en países desarrollados se ha estimado entre 2 %-5 %, asociada con una alta morbimortalidad. La identificación etiológica a veces es difícil, y requiere de métodos diagnósticos, como la videocápsula endoscópica (VCE).
Objetivo: el objeto del presente estudio fue caracterizar los hallazgos de esta técnica en pacientes con anemia ferropénica inexplicada.
Materiales y métodos: estudio descriptivo, observacional y retrospectivo. Se describen los hallazgos de VCE (PillCamSB2-SB3) en todos los pacientes atendidos entre 2011 y 2019. Los hallazgos se interpretaron según la clasificación de Saurin: normal (P0), potencial incierto (P1) y alto potencial de sangrado (P2).
Resultados: del total de 490 VCE realizadas durante el período del estudio, 155 se efectuaron con indicación de anemia ferropénica; 106 fueron mujeres (68,4 %) y la edad media fue de 57,1 ± 16,6 años. Las comorbilidades principales fueron cardiovasculares en 23 (18,3 %) e hipertensión arterial en 16 (12,6 %). La ingesta de antiplaquetarios se presentó en 18 (15,4 %) y anticoagulantes en 6 (5,1 %). Las lesiones en el intestino delgado fueron vasculares en 44 estudios (28,4 %), inflamatorias en 33 (21,2 %) y neoplásicas en 7 (4,5 %). Las angiectasias fueron las lesiones más frecuentes en 33 casos (21,3 %). En 53 VCE se presentaron lesiones P2 (34,2 %).
Conclusiones: la VCE es útil en el estudio de la anemia ferropénica, y ayuda a detectar hallazgos positivos en el intestino medio en 3 de cada 4 pacientes en los cuales se indica su uso. Las lesiones P2 significativas más frecuentes fueron las vasculares. Estos hallazgos permiten enfocar un tratamiento adecuado.

Introducción: la enfermedad inflamatoria intestinal (EII) es una enfermedad inmunomediada, cuya incidencia en Latinoamérica ha aumentado en los últimos años.

Objetivo: analizar las características demográficas y clínicas de los pacientes con EII tratados en un hospital universitario y presentar los datos epidemiológicos con respecto a otros centros en Colombia.

Pacientes y métodos: estudio descriptivo de pacientes con EII (1996-2019) en el Hospital Universitario Fundación Santa Fe de Bogotá. Análisis de datos de centros de Medellín, Cali, Bogotá y Cartagena.

Resultados: de 386 pacientes, 277 presentaron colitis ulcerativa (CU), 102 enfermedad de Crohn (EC) y 7 colitis no clasificable. La EII fue más frecuente en mujeres (53 %). La mortalidad fue menor de 1 %. El compromiso de la CU fue principalmente la pancolitis (42,6 %). Entre mayor la extensión de la enfermedad, más alta fue la tasa de hospitalización y cirugías (OR 3,70; p < 0,01). El 13 % de los pacientes con CU recibió biológicos. El compromiso por la EC fue principalmente ileocolónico (43,6 %) e ileal (43,6 %). El patrón clínico predominante de la EC fue estenosante (50%). El 45 % recibió biológicos y 56% cirugía. La colangitis esclerosante primaria (CEP) se encontró en 4 % de los pacientes (n = 15). Dos pacientes con CEP desarrollaron cáncer colorrectal (OR 4,18; p 0,008), mientras que 13 pacientes con CU desarrollaron cáncer de colon y 7 cambios displásicos. 3 pacientes con EC desarrollaron cáncer de colon.

Conclusiones: se compararon los resultados en relación con otros centros de referencia. Encontramos tendencias similares en el comportamiento clínico y en el tratamiento de la EII, con mayores tazas de hospitalizaciones y cirugías en nuestros casos.

Authors: Khan Farooq , Rehman Habib , Asif Syed , KHAN MUHAMMAD , Khan Muhammad
Published: March 2022

The phenomena in which an extra electron is removed from a negative ion
is called photo-detachment. Photo-detachment is important phenomena,
used to find the structure of anions, particulary to find the electron
affinities. In this paper, we present theoretically the induced efffects
in the photo-detached of tri-atomic anion H3 near hard reflecting wall
or surface. For the photo-detachment process, a Z-polarized coherent
source of radiations (laser) is used to kick electrons from H3 like
anion in the domain of a hard reflecting surface. Imaging method is
adopted to derive the generalized detached electron wave, differential
cross-section and the total cross-section Analytically. Numerical
solutions (simulations) for total electron flux and the total
cross-section is also presented. In the electron flux, shows visible
oscillation and hence the induced effect of surface in the interference.
It is depicted that the reflecting hard wall strongly affects the flux
and total photo-detachment cross-section
Digestibilidad in vivo de morera (Morus alba), reemplazando el alimento concentrado en curies (Cavia porcellus)
Authors: Villegas Daniel Enrique , Roa Vega María Ligia
Published: March 2022

El cuy (Cavia porcellus) es una especie precoz, que se adapta a condiciones adversas, por su resistencia a enfermedades. Además, es fuente proteína y una opción de seguridad alimentaria para la población. Los estudios sobre alternativas de alimentación para curíes, son limitados en Colombia, porque se desconocerse su comportamiento cuando se les suministra forrajeras propias de la región tropical. Actualmente se le proporciona concentrado para conejos, lo cual no suple los requerimientos del cuy en un sistema productivo. La morera (Morus alba) (Mo) es una excelente fuente de proteína, energía, de alta palatabilidad y aceptación por parte de los animales. El objetivo del trabajo fue determinar la digestibilidad In vivo en cuyes suministrando Mo, ad libitum como reemplazó parcial de un concentrado comercial (CC), se utilizaron 24 cuyes machos de peso promedio 1000 ± 100 gr distribuidos en un diseño completamente al azar, con cuatro tratamientos (T) , tres repeticiones con dos unidades experimentales cada una: T1: Mo más CC al 1% de su peso vivo (PV) T2: Mo con CC al 2% de PV , T3 Mo más CC al 3 % de PV y T4: Mo únicamente. Se sometieron los animales a un periodo de acostumbramiento de cinco días y cuatro de toma de excretas las cuales fueron analizadas en el laboratorio de Nutrición animal. Se hicieron pruebas comparación múltiple utilizando el método Tukey. Las variables evaluadas fueron coeficientes de digestibilidad de: materia seca (MS), Proteína (PR), Grasa (GR), Extracto no nitrogenado (ENN), fibra cruda (FC), % nutrientes digestibles totales (NDT); Los coeficientes de digestibilidad fueron mayores (P<0,05) para T2 Y T3 en MS (0,62 y 0,68) Pr (0,67 y 0,73), ENN (0,56y 0,64) y NDT (61,29 y 68,09), y entre estos dos tratamientos no existieron evidencias significativas según la prueba de Tukey para las anteriores variables. Por su parte el coeficiente de digestibilidad de GR y la excreción de MS no observaron una varianza significativa en los cuatro tratamientos. El T3 fue el que obtuvo los mayores coeficientes de digestibilidad (P<0,05) de FC (0,74). Se concluye que en cuyes se puede remplazar el CC por Mo hasta el 3% del PV, observándose un efecto positivo de este forraje sobre la digestibilidad de la MS, PR y ENN, no obstante, el reemplazo al 2% de su peso vivo en materia seca no genera diferencias significativas con respecto al 3% generando así un ahorro de 1% en la dieta con el suministro del concentrado.

First year of child development is marked by many changes of which eruption of first tooth into the oral cavity is considered an important milestone. It has shown to follow a chronology and has been established in the literature corresponding to the date when tooth erupts into the oral cavity. Depending on hereditary, endocrine and environmental factors they may be subjected to variations. However, at times, chronology of tooth eruption suffers a more significant alteration in terms of onset, with the teeth being present at birth or arise during the first month of life poses greater concern due to feeding difficulties along with societal unpleasant reaction towards it. Objective of this paper is to present case series of natal and neonatal teeth with considerations in the management.
Benefits and Challenges Associated with the Use of Social Media Applications in Education at the Basic Education Level in the Bolga–East District of Ghana, West Africa
Authors: Alagbela Alaric Awingura
Published: March 2022

Social Media has taken over the globe by storm. Its effects cut across all facets of humankind. This is especially so in the area of education. Depending on how managers of the education sectors apply it, Social Media has advantages and disadvantages. This study is a case study of the qualitative approach to research. The study sought to explore the benefits and challenges associated with the use of Social Media and its applications at the basic level of education in the Bolga- East District of the Upper East Region of Ghana, West Africa. In view of this objective, ten (10) participants, thus two (2) each from the five junior high schools from the district capital, Zuarungu, who had been teaching Information, Communication and Technology (ICT) were purposely selected through the intensity case sampling technique to constitute the sample size. An in-depth interview guide was employed in collecting data from the participants. The study revealed that benefits or opportunities concerning Social Media usage in education include the crucial role it plays in the search for information for research and collaborations, the sharing of information and other relevant educational materials to group members among others. However, the challenges associated with its usage include exposing young learners to uneducated and morally bankrupt materials, making students and teachers miss instructional hours through its addiction and the spread of fictitious information. Additionally, the study revealed that there are no specific and district- wide guidelines concerning the use of Social Media tools at the basic education level. The study thus recommends that educational authorities of the Ghana Education Service publish specific guidelines regulating its usage to the benefit of students’ education. Parents and guardians should also monitor the activities of their wards at home to ensure that Social Media tools are used solely for academic work.

This case study aimed to report blood markers and resting respiratory rate (RR) oscillations at sea level, during a 5-wk 3900 m altitude sojourn, and after returning to sea level in a 36-year-old professional wheelchair marathoner. Outcome measures plasma erythropoietin (EPO) concentration, hemoglobin, reticulocytes count, erythrocytes and hematocrit as well as RR were measured upon wakening 7-weeks pre-altitude, 7-days pre-altitude, 35 hours after arrival to altitude, on days 8, 15, 21, 28 and 35 at altitude, 6 and 16 days after returning to sea level. EPO increased up to 259 % (31.6 U l-1) 35 hours upon arrival at altitude and decreased below pre-altitude level (12.2 U l-1) on the 21st day of the camp (8.7 U l-1), reaching the lowest values 16 days after returning from altitude (1.9 U l-1). All blood parameters, except for reticulocytes, increased (range: +17.9 to +23.8%) after 35 days of altitude exposure. Compared to pre-altitude, RR increased during the first week of exposure to hypoxic conditions and remained elevated throughout the camp until the fifth week (5.1±0.4 vs. 9.1±1.6 and 6.6±0.8 breaths min-1; Cohen´s d = +3.4 and +2.4, respectively). A 5-wk high-altitude sojourn triggered polycythemia and elevations in RR (as indicators of effective hypoxic acclimatization) in a professional wheelchair-marathoner.

Published: March 2022

The terminological profiles of specialists are drawn up based on publications from the digital library eLIBRARY. By averaging the individual terminological profiles, it is possible to draw up a generalized profile (“portrait”) of a small research team (a department, laboratory, or sector). Comparison of individual profiles with the use of proximity measures (for example, a cosine measure) makes it possible to group similar profiles and identify groups of employees who conduct research in the same subject area. This helps determine the research team specialization by means of Text Mining tools without using subjective expert assessments. The results obtained using the profile approach are confirmed by constructing graphs of co-authorship and a graph of terms in the Gephi computer program. The compilation of terminological profiles was also used in the development of personalized scientific activity support systems. This system is intended for helping the user (a specialist in a subject area) in choosing relevant scientific conferences and searching for useful (pertinent as far as possible) publications. For describing text documents, a vector model is used, and the weights of terms are determined by calculating the term occurrence frequency (or the tfc-weighting formula). At the preprocessing stage, the stop-words and rarely encountered words are removed, and lemmatization is carried out. The developed profile approach has been approbated on the example of a small research team specializing in computer science. The terminological profiles were constructed and analyzed, based on which the areas in which the team members specialize have been identified, and a personalized scientific activity support system has been developed, that tracks, in an automated mode, publications in the eLIBRARY in one of the relevant areas (Data Mining).

The article discusses the results of using a standard algorithm for linearly locating the sources of acoustic emission signals generated by a broadband acoustic emission (AE) transducer mounted on the surface of a steel plate with sizes 1000×650×7 mm. To generate AE impulses with an amplitude of um = 55–100 dB, the electronic simulator’s difference of potentials was varied in the range of 10–300 V. As a result of laboratory experiments, the reduced error γ of the standard linear location algorithm was calculated. The maximum error equal to γ = 16.3% was recorded at the coordinate X = 100 mm in locating the source of acoustic signals with an amplitude of less than 60 dB and the antenna array basic size B = 800 mm. The minimum error equal to γ = 2.69% was recorded with the electronic simulator installed at the coordinate X = 400 mm. It is shown that the maximum error of the standard algorithm is observed in locating the sources of low-amplitude AE signals situated near the antenna array receiving transducers. The AE source detection probability as a function of recorded impulse amplitude is quantified. For determining the AE source detection probability p, the flow of recorded signals was divided into three amplitude ranges: 40–60 dB, 60–75 dB, and 75–100 dB. For the sources of acoustic signals with an amplitude of less than 60 dB and located at the coordinates X = 100, 200, 600, and 700 mm, the parameter p value tends to zero. It has been revealed in processing the experimental study results that the AE source detection probability increases with a growth in the maximum amplitude of the recorded signals. For AE impulses with an amplitude above 75 dB, the parameter p value approaches unity regardless of the source location. It has been determined that the error of the standard linear location algorithm depends on the distance between the AE source and the antenna array receiving transducers. The dependence p(X, um) has been demonstrated as a numerical assessment of the way in which the above-mentioned factors influence the obtained location picture results.

Published: March 2022

Spent petroleum products can be efficiently used as an energy source in industrial thermal power engineering. Matters concerned with the energy efficiency and environmental safety of using this type of fuel and development of burners for spent petroleum products are extremely relevant. To analyze the energy efficiency of industrial plants that use spent petroleum products as fuel, the heating value of these products has to be known. The data on the lower heating value and viscosity of various petroleum fuels published in the literature are systematized. The results obtained make it possible to estimate the heating value of spent petroleum products by using their viscosity as a parameter. A set of works aimed at developing an evaporative burner for high-quality combustion of various spent petroleum products has been accomplished. Based on experimental studies of the combustion of various spent petroleum products in the evaporative burner, relationships between the viscosity, lower heating value, and flame length and temperature are revealed. By using the obtained relationships between the thermal parameters characterizing the combustion of spent petroleum products, it becomes possible to assess the possibility of effectively neutralizing such pollutants as halogens and polychlorinated biphenyls. The boundary of the domain in which spent petroleum products can be combusted in an environmentally efficient manner with neutralizing such pollutants as halogens and polychlorinated biphenyls has been determined and described analytically. Dependences of the maximum allowable concentrations of pollutants in spent petroleum products on their viscosity, lower heating value, and flame temperature are presented. The obtained results can be used to develop domestic regulatory documents on energy efficient and environmentally friendly combustion of spent petroleum products in thermal engineering plants.

La place occupée par la religion dans le champ politique n’a cessé de s’affirmer ces dernières décennies. Alors, le recours aux arguments religieux reste une pratique courante chez les acteurs politiques de tous bords, nombre de mouvements religieux ont vu leur assise et leur influence consolidées ou contestées. L'influence des religions sur l'oppression des femmes fait penser aujourd'hui aux tchadors, burkas, hidjabs, etc., au nom de l'islam, certains prétendent, et trop souvent réussissent à enfermer les femmes.

Il sera question dans cet article de la place des femmes dans l'univers politique du Cameroun, dans une perspective anthropologique et socio-historique. Et c'est à partir de ce lieu que sera proposée une approche du statut de la musulmane dans la société politique, des représentations dont elles sont l'objet, de la manière dont elles s'inscrivent dans le paysage social. Contribution modeste à l'approfondissement de l'analyse des liens qui se sont tissés entre religion et société au Cameroun.
Soğuk Savaş Dönemi Güvenlik Algısında Yaşanan Değişim ve Uluslararası Sistemin Değişen Dinamikleri
Authors: TOKATLI Seda Gözde
Published: March 2022

Soğuk Savaş döneminde uluslararası yapının yön değiştirmesiyle güvenlik kavramına yönelik yeni yaklaşımlar ön plana çıkmıştır. Uluslararası sistem içerisinde ABD ve Sovyetler Birliği arasında yaşanan güç mücadelesinin temelini oluşturan ideolojik farklılıklar zamanla ekonomik, askeri ve siyasi zeminde de kendisini göstermeye başlamıştır. İki kutuplu yapı içerisinde yaşanan güvenlik ikilemi tarafların kendi güvenlik ağlarını inşa etmesinde, alternatif ittifak oluşumlarını desteklemesinde ve uluslararası örgütler aracılığıyla kendi bloklarını kurmasına yol açmıştır. Soğuk Savaş döneminde iki kutuplu yapı içerisinde oluşan güvenlik ikilemi, gücün ulusal çıkar çerçevesinde ele alınması ve devletlerin güç bileşenlerinden askeri güce daha fazla önem vermesi neo-realist kuramın artan önemini ortaya çıkarmaktadır. Uluslararası sistem içerisinde ABD ve Sovyetler Birliği sıcak çatışma içerisine girmeden son derece başarılı caydırma, çevreleme ve dengeleme stratejileri uygulamayı başarmıştır. Soğuk Savaş döneminde hissedilen ortak tehdit algısı ittifak üyelerini bir arada hareket etmeye zorlarken, yapısal değişikliklerin yön değiştirmesi ittifak ilişkilerinin yeniden şekillenmesine ve çıkar odaklı yaklaşımların savaş sonrası dönemde daha fazla ön plana çıkmasına yol açmıştır. Bu çalışmada, iki kutuplu yapı içerisinde yer alan ABD ve Sovyetler Birliği’nin benimsediği ulusal güvenlik stratejilerine yer verilecek, uygulamaya konan güvenlik doktrinleri karşılaştırmalı olarak analiz edilecektir. Soğuk Savaş döneminde uluslararası örgütlerin güç dengeleri üzerinde oynadığı rolün önemi de vurgulanacaktır.
Niş Sancağı’nın İdari yapısı (1839- 1878)
Authors: PAY Salih , OSMANI Mead
Published: March 2022

Balkanlar’daki eski yerleşim merkezlerinden biri olan Niş, 1386-1878 yılları arasında Osmanlı hâkimiyetinde kalmıştır. Başlangıçta Rumeli beylerbeyliğine, sonraları ise Semendire’ye bağlanmış ve bu statüsü XIX. yüzyıla kadar da devam etmiştir. XIX. yüzyıl aynı zamanda Niş’in idarî statüsünde çok sık değişikliklerin meydana geldiği yıllardır. Nitekim 1839’da civarındaki bazı yerleşim alanlarının da ilavesiyle eyalete dönüştürülerek başına Ferik Vâsıf Paşa tayin edilmiş, 1847’de Sofya, Smakov ve Köstendil’in de bağlanmasıyla sınırları genişletilmiştir. Ancak Rumeli’de başlayan isyan hareketlerine yönelik olarak alınan tedbirler sebebiyle önce vilayete dönüştürülerek valiliğine Midhat Paşa getirilmiş, akabinde ise 1864’te Silistre, Vidin ve Niş birleştirilelerek Tuna Vilâyeti oluşturulmuştur. Fakat bu değişiklik de uzun süreli olamamış, 1870’te sancak statüsüyle Prizren vilâyetine bağlanmıştır. Niş, dört yıl sonra, 1874’te İşkodra ve Prizren’nin birleştirilmesiyle Manastır adıyla yeni bir vilâyet oluşturulunca, bu sefer tekrar Tuna’ya bağlanmıştır. Bununla birlikte Balkanlar’da sonu gelmeyen hareketlilik, 1876’da Tırnova ve Sofya adlarında iki Bulgar vilâyetinin oluşturulmasıyla sonuçlanınca bu sefer de Sofya’ya bağlanmıştır. Lakin bu da çok kısa sürmüş ve nihayet Kosova’ya bağlanmıştır. Kosova, aynı zamanda Niş’in Osmanlı hâkimiyetinde iken bağlandığı son merkezdir. Nitekim Niş, 1877-78 Osmanlı-Rus Savaşı akabinde yapılan Berlin Kongresi’yle Sırbistan’a terk edilen yerler arasına dâhil edilmiştir.

Background: The COVID-19 pandemic has induced a substantial burden on healthcare organizations, with increased workload and stress for healthcare providers. Healthcare professionals working on the frontline are vulnerable to stress, putting their psychological and mental wellbeing in considerable jeopardy.
Methods: This is a cross-sectional study using data collected from a self-administered questionnaire that was distributed electronically to healthcare workers. The validated Kessler Psychological Distress Scale (K10) and the General Self-Efficacy Scale (GSE) were used to measure the level of stress of the healthcare professionals and the psychological impact of the pandemic on them.
Results: Two hundred and thirteen participants were included. A third of the responders (34.3%) were previously infected with COVID-19, while 72.3% had to self-isolate during the pandemic. The average score for the K10 questionnaire was 24.8 ± 9 out of 50, where almost a third of the responders (33.3%) had very high psychological stress levels. The average score for the GSE was 30.2 ± 5.3 points out of 40. Nurses and physicians (p = 0.033) showed significantly higher scores on the K10 survey. Furthermore, nurses between ages 20 and 29 (p = 0.025) and nurses of any age (p = 0.009) had significantly high levels of psychological stress.
Conclusion: Healthcare professionals are at significant risk of psychological and mental adverse effects, particularly nurses on the frontline. Such findings should drive initiatives to prepare task forces that can put forward and implement strategies to minimize the risk imposed on the psychological and mental wellbeing of frontline health workers.

Penelitian ini menggunakan jenis penelitian eksperimen dan menggunakan desain penelitian rancang acak lengkap. Ada dua kelompok dalam penelitian ini, yaitu kelompok kontrol yang tidak di papar medan magnet dan kelompok eksperimen yang di papar medan magnet. Pada kelompok eksperimen diberikan perlakuan dengan pemaparan medan magnet Extremely Low Frequency dengan intensitas 300 Î¼T dan 500 Î¼T dan waktu paparan 60 menit, 90 menit, dan 120 menit. Sampel yang digunakan sebanyak 145 sampel udang yang berukuran sama. Kelompok eksperimen ada 120 sampel dan kelompok kontrol ada 25 sampel. Teknik analisis data yang digunakan menggunakan SPSS 22 dengan uji Kruskal-Wallis. Hasil dari teknik analisis data tersebut yaitu paparan medan magnet ELF (Extremely Low Frequency) berpengaruh terhadap pH udang vaname.Â Extremely Low-Frequency magnetic field is a spectrum of electromagnetic waves, where the frequency is less than 300 Hz and includes non-ionizing radiation. This study aims to examine the effect of exposure to ELF (Extremely Low Frequency) magnetic fields on Vannamei shrimp's pH. This research uses experimental research and uses completely randomized design research. This study has two groups: the control group, which is not exposed to magnetic fields, and the experimental group exposed to magnetic fields. The experimental group was given treatment with exposure to Extremely Low-Frequency magnetic fields with an intensity of 300 Î¼T and 500 Î¼T and exposure time of 60 minutes, 90 minutes, and 120 minutes. The samples used were 145 shrimp samples of the same size. The experimental group had 120 samples, and the control group had 25 samples. The data analysis technique used was SPSS 22 with the Kruskal-Wallis test. The result of the data analysis technique is that exposure to an Extremely Low-Frequency magnetic field affects Vannamei shrimp's pH. The pH value of the control group was higher than the experimental group. ELF magnetic exposure can suppress the growth of acid-forming microorganisms in shrimp. It can be proven that the experimental group experienced a significant increase in pH value, while the control group experienced a drastic increase in pH value.

Penelitian ini bertujuan untuk mengkaji potensi aplikasi keramik (Mg0,8Zn0,2)TiO3+4wt% Bi2O3 (disingkat MZT02+4wt%Bi2O3) sebagai resonator pada rangkaian dielectric resonator oscillator (DRO) yang bekerja pada daerah frekuensi gelombang mikro, serta menguji struktur, mikrostruktur dan densitas bulk keramik. Fabrikasi keramik dilakukan dengan ball-milling antara serbuk kristalin MZT02 dengan 4wt% serbuk Bi2O3 pada kecepatan 500 rpm selama 5 jam. Serbuk hasil milling dikompaksi dengan hydraulic-hand press dan cylindrical die press untuk menghasilkan pelet. Semua pelet disinter pada suhu 1100Â°C selama 4, 6 dan 8 jam untuk menjadi keramik. Struktur keramik dengan waktu penahanan 4 dan 6 jam mengandung fasa MgTiO3=(97,87Â±8,24) %molar, sisanya fasa TiO2 rutil. Keramik dengan penahanan 8 jam mengandung fasa MgTiO3=(98,44Â±2,07) %molar, MgTi2O5=(1,49Â±0,30) %molar dan sisanya TiO2 rutil. Bertambahnya waktu tahan sinter relatif tidak menyebabkan perubahan ukuran parameter kisi, volume sel satuan sedikit berkurang dan densitas bulk juga berkurang dari 2,792, 2,776 menjadi 2,745 g/cm3. Mikrostruktur ketiga keramik berupa gumpalan butir dengan ukuran rata-rata 0,3-1,2 Î¼m disertai pori-pori. Karakterisasi DRO merekam frekuensi resonansi pada posisi yang sama untuk ketiga keramik, yaitu 5,12 GHz memberi bukti bahwa keramik uji dapat diaplikasikan sebagai resonator DRO pada frekuensi gelombang mikro dan variasi waktu tahan sinter tidak merubah performa tersebut.Â This study aims to examine the potential application of (Mg0.8Zn0.2)TiO3+ 4wt% Bi2O3 (abbreviated: MZT02+4wt% Bi2O3) ceramics as a resonator in a dielectric resonator oscillator (DRO) circuit operating in microwave frequencies and to examine its structure, microstructure and bulk density. Ceramic fabrication was carried out by ball-milling between MZT02 crystalline powder and 4wt% Bi2O3 powder at 500 rpm for 5 h. The milled powder was compacted using a hydraulic-hand press and a cylindrical die press to produce pellets. All pellets were sintered at 1100Â°C for 4, 6 and 8 h to become ceramics. The ceramic structure with 4 and 6 h holding time contains MgTiO3 phase = (97.87 Â± 8.24)% molar, the rest was TiO2 rutile phase. Ceramic with 8 h contained MgTiO3phase = (98.44 Â± 2.07)% molar, MgTi2O5 = (1.49 Â± 0.30) molar% and the remaining TiO2 rutile. Increasing the sinter holding time relatively did not change in the lattice parameter sizes, the unit cell volume was slightly reduced and the bulk density was also reduced from 2.792, 2.776 to 2.745 g/cm3. Microstructure of the three ceramics contain groups of grains with an average size of 0.3-1.2 Î¼m along with pores. DRO characterization recorded the resonant frequency at the same position for the three ceramics, namely 5.12 GHz, providing evidence that the ceramics can be applied as a DRO resonator at microwave frequencies and the variation in sinter holding time did not change this performance
