Published: June 2022

Los autores presentan los hallazgos de realizar una Revisión Sistemática de la Literatura en torno a iniciativas educativas que incorporan la tecnología de Realidad Aumentada (RA). Sin lugar a dudas, la RA es una tecnología emergente que ha tomado popularidad en las últimas dos décadas, ya que permite combinar en tiempo real objetos del mundo real con objetos digitales a través de diferentes soportes tecnológicos, creando de esta manera una nueva realidad con la que el estudiante puede interactuar y aprender. De los hallazgos, es posible destacar que: (1) la mitad de los estudios han sido aplicados en el nivel superior, (2) poco más de tres cuartas partes son iniciativas que sirven de apoyo a la modalidad presencial, (3) las iniciativas sirven de apoyo para promover conocimientos en los primeros tres niveles de la Taxonomía de Bloom, (4) el paradigma más utilizado como sustento de las iniciativas, es el conductista y (5) prácticamente todas las iniciativas ven a la RA solo como un complemento para la estrategia instruccional.

The authors present the findings of carrying out a Systematic Review of Literature around educational initiatives that incorporate Augmented Reality (AR) technology. Undoubtedly, AR is an emerging technology that has become popular in the last two decades, since it allows real-time objects to be combined with digital objects in real time through different technological supports, thus creating a new reality with which the student can interact and learn. From the findings it is possible to highlight that: (1) half of the studies have been applied at the higher level, (2) just over three-quarters are initiatives that support the face-to-face modality, (3) the initiatives serve of support to promote knowledge in the first three levels of Bloom's Taxonomy, (4) the paradigm most used to support initiatives, is the behaviorist one and (5) practically all initiatives see AR only as a complement to the instructional strategy.

Granulomatous Mastitis with Corynebacterium Infection
Authors: Tamura Yu
Published: June 2022

Background: Idiopathic granulomatous mastitis (IGM) is a rare relapsing benign, chronic inflammatory breast disease characterized by infiltration of inflammatory cells including multinucleated giant cells. Recently, it has been suggested that infection with Corynebacterium species (spp.) may be involved in the onset of the disease. Therefore, the aim of this article is to summarize the previous IGM reports related to Corynebacterium spp.Methods: I used the terms "granulomatous mastitis Corynebacterium" in PubMed and "granulomatous mastitis Corynebacterium" with Japanese in Google Scholar, which resulted in 63 English articles and 71 Japanese articles. I read all the abstracts and summarized the recent articles with Corynebacterium in the title.Results: In 16 English articles and 4 Japanese ones, the most common Corynebacterium spp. was Corynebacterium kroppenstedtii, followed by Corynebacterium tuberculostearium. Conclusion: Corynebacterium infection is widely detected with IGM. In addition to bacterial culture, real-time polymerase chain reaction and formalin-fixed, paraffin-embedded biopsy specimens’ analysis can be used to detect Corynebacterium spp.

Authors: Jafari Maryam
Published: June 2022

Background: Idiopathic granulomatous mastitis (IGM) is one of the uncommon benign relapsing diseases of the breast and the imaging features of IGM can be indistinguishable from invasive or inflammatory breast carcinoma. Therefore, the assessment of the ultrasound features could be diagnostically helpful. Material and Methods: This retrospective research involved a total of 26 patients who had a final pathologic diagnosis of IGM and who underwent high-resolution ultrasound (US) and color Doppler evaluation.Results: Overall, 26 patients met the inclusion criteria. The age range of the patients was between 24 and 52 years old with an average of 34.81. About half of the patients (53.8%) reported pain as a presenting symptom and the most common physical finding was a palpable mass in 53.8% of the cases. Ultrasonography revealed the most common mass shape to be oval and irregular both with a frequency of 47.1%. Mass margins were mostly indistinct (70.6%) while angular and circumscribed margins were also seen. Heterogeneous echogenicity was observed in 71.4%, increased echogenicity of perilesional fat in 84.6%, posterior acoustic enhancement in 57.7%, peripheral vascularity in 30.8%, and subcutaneous collections in 19% of the patients., Internal vascularity was seen in 7% of the cases.Conclusion: In the US of IGM, increased echogenicity of subcutaneous and perilesional fat were a common ultrasound feature (84.6%) while perilesional fat edema has not been mentioned in previous studies. In this study, other ultrasound features of IGM such as tubular extension, subcutaneous collection, indeterminate irregular masses, and collections were observed. They may contribute to the diagnosis of granulomatous mastitis in a proper clinical setting.
ВИЗНАЧЕННЯ ІМУНОСТИМУЛЮЮЧОЇ ДІЇ ПРЕПАРАТУ «ІНКОМБІВІТ»
Authors: Калюжна Т. М.
Published: June 2022

За останні часи багато уваги приділяється вивчення стану імунної системи тварин. В останні роки при імунодефіцитах у тварин все більшого значення набуває фармакологічна імунокорекція шляхом застосування імуномодуляторів. Сильний відбір у пошуках вищої швидкості зростання бройлерів призвів до таких побічних ефектів, як порушення обміну речовин, низька реактивність імунної системи. Недостатнє постачання поживними речовинами може послабити імунну систему. Більш безпечним для підвищення імунного потенціалу тварин є застосування вітамінів, мінеральних речовин та інших адаптогенів. Рівень набутого імунітету залежить від багатьох факторів, особливо у момент вакцинації чи зараження. Вакцини взаємодіють з імунною системою, викликаючи таку ж імунну відповідь, як і при природній інфекції у птахів. Існують різні способи доставки антигенів курчатам з метою імунізації. В останні роки при імунодефіцитах у тварин все більшого значення набуває фармакологічна імунокорекція шляхом застосування імуномодуляторів різної природи, які можуть підвищувати або знижувати рівень імунної відповіді. Застосування методів стимуляції імунної функції у тварин у ветеринарній медицині пояснюється тим, що в умовах промислового тваринництва у тварин нерідко виникає імунодефіцит, внаслідок чого вони піддаються різним захворюванням. Імуномодуляція проводиться для підвищення продуктивності курчат, підвищення стійкості організму до патогенів. З такою метою ми застосовували препарат «Інкомбівіт». Це комбінований препарат, який містить жиро – та водорозчинні вітаміни, мікроелементи та амінокислоти, що нормалізують обмін речовин, підвищують загальну резистентність, покращують продуктивність, збереженість та репродуктивні функції тварин. Препарат вміщує лише ендогенно доступні біологічно активні речовини, які є природними компонентом кормів для тварин та природно присутні в тканинах тварин. Дослідження препарату «Інкомбівіт» проводили в ідентичних умовах утримання контрольної та дослідної групи. Дослідний препарат випоювали через систему водопостачання після заповнення пташника, та при вакцинації поголів’я. Проводили лабораторні дослідження проб сироватки крові. Спостерігали підвищення кількості В-, Т- лімфоцитів, глобулінів, гемоглобіну, загального білка в сироватці крові та інших показників, що свідчить про посилений процес антитілоутворення після імунізації.
“When the Banks Say No, We Say Yes!” Decoding Mortgage Advertisement Appeals In a Decoupled Housing Market
Authors: Radlovic Natasa
Published: June 2022

Home prices in Toronto are decoupled from incomes, with the average home now costing approximately ten times more than the average household income. Mortgage advertisements are an important communication vehicle to study, particularly in a decoupled housing market. Determining the appeals advertisers use can indicate whether consumers are being guided and informed of mortgage product options or if they are being persuaded by emotional appeals to make a major financial decision. This major research paper uses content analysis to examine advertising tactics used by mortgage lenders and brokers on Facebook and Instagram to appeal to home buyers in a decoupled market. The findings focus on three specific elements extracted from the advertisements, including the display of an interest rate, the call to action that is used, and whether the fine print is shown on the ad. These elements will determine which institutions use more persuasive or informational appeals.
DO THE LOANS OF CONVENTIONAL BANKS CROWDING-OUT THE LOANS OF PARTICIPATION BANKS?
Authors: DİLBER Caner , HATİPOĞLU Mercan
Published: June 2022

A dual banking system has emerged in Turkey with the participation banks starting to operate since the mid-1980s. Therefore, it is important in terms of financial policies whether the two types of banking models are compatible or incompatible with each other. The aim of this study is to investigate how credits of conventional banks affect participation banks in the context of Turkey. Monthly observations of participation and conventional banks credit during the period between 01/2005 - 02/2022 are used in study. Kalman filter method with simple regression analysis was preferred as a model. The findings implied that the conventional banking model did not hinder participation banks in the credit market.
KINETICS AND OXIDATION OF THE REACTIONS BETWEEN DITHIONITE ION AND NITROCELLULOSE IN ACIDIC PHASE
Authors: UMORU PATRICIA , EFFIONG UDOH
Published: June 2022

Kinetics and oxidation of the reactions between dithionite ion and nitrocellulose was studied in acidic phase under the condition of excess [S2O42-] at T = 29 ± 1oC, [H+] = 1.0 × 10-2 mol dm-3, I = 1.0 mol dm-3 (Na2SO4) and λmax = 360 nanometer. The oxidation-reduction reasult for NC+ with dithionite ion displayed a 1:2 mole ratio. The reaction showed first order in terms of the oxidant [NC+] as well as first order in terms of the reductant [S2O42-]. The rate of reaction indicated a first order relationship in terms of acid ion concentration. The reaction rate law is given as: k2 = a + b [H+] where a = Intercept, b = Slope. The rate of reaction increased with an increase in the moles of sulphuric acid added. This implies great stability of NC+ in an aqueous acidic medium. The rate decreased with an increase in sodium sulphate concentration. The spectroscopic investigation gave no signal for the formation of an intermediate complex. Based on the results obtained for the non-formation of intermediate complex, a plausible mechanism that favoured the outer-sphere mechanism was proposed for the studied reaction.
European Union’s Securitization and Favoritism Phenomenon: Lesson Learned from the 2015 Europe’s Migrant Crisis
Authors: Perbawani Firsty Chintya Laksmi
Published: June 2022

This research article aims to portray the phenomenon of how Europe’s perspective and attitudes toward migration. Race, culture, and politics all play a prominent role in Europe’s reception of migrants. This article precisely focused on the role of the European Union (EU) during the 2015 migrant crisis. As Europe faced the struggle where 1.3 million refugees and migrants illegally entered Europe by the sea in 2015, compared to roughly 200,000 in 2014. The author argues that European countries have responded to the issue discordly, with some welcoming migrants and others rejecting them. This article founds the reasons, namely: (1) securitization within the EU, i.e., raising the issue of migration as a “matter of European security”; and (2) the phenomenon of favoritism, as evidenced by selective solidarity, racism, and anti-immigrant rhetoric. This article attests that both securitization and favoritism culture in Europe must be recalculated and used as lessons learned so that there is no bias in allowing forthcoming migrants and so that the EU continues to exist.

This research aimed to assess the concentrations of As, Cd, Cr, Pb, and Zn in Swarna rice (NR) collected from Kaharole, Biral, and Sadar Upazilla of Dinajpur and their reduction by cooking associated submerged fermentation. The levels of As, Cd, Cr, and Zn were lower than the individual metal’s safe limit, but the (Pb) concentrations were found at 0.2582, 0.9028, 0.9164, 0.7303, 0.8574, 0.6440, 0.6622 mg/kg in SR02, SR04, SR05, SR06, SR07, SR08, and SR09 of NR samples, respectively, which were higher than the (Pb) safe limit. Notably, the reduced hazard index (HI) was found from the standard limit 1 for all fermented rice (FR) samples and all boiled rice (BR) samples except SR05. Six different Streptococcus sp. strains were identified in FR that suggested Streptococcal involvement in leaching of HMs during submerged-fermentation. Consequently, compared to NR, hazard index and cumulative carcinogenic risk were declined by several folds in FR.

Published: June 2022

Ever since the discovery of jute endophytes, testing their potential for commercial uses has been a matter of interest. Considering the same, jute endophyte Micrococcus luteus MBL-Bac7, capable of producing extracellular proteases, was selected for in vitro and in silico analysis to assess its role as a bating agent required in rawhide processing. The presence of extracellular protease was confirmed from the plate assay. As the enzyme is tested for commercial use, the effect of various metal ions and reaction conditions (pH, temperature) have been optimized. The protease activity appears to be retained even at 85°C. It also showed significant activity in a wide range of pH (pH 3.0-8.5). Metal ion Mn2+ increased the protease activity significantly, but Fe2+, Zn2+, and Co2+ ions showed the opposite effect. Molecular identification of the protease was done from the whole genome sequence data. Using PSORTb v.3.0.2, SecretomeP-1.0, TMHMM-2.0, and protein molecular weight software, the physicochemical properties of the protease were predicted. The isolated protease shared a strong evolutionary link with Micrococcus species' S8 family serine peptidase. Finally, in the bating of cowhide, effects similar to that of commercial agents were obtained during finger prick, lastometer, and tensile tests. The findings of this study corroborate the possibility of using this protease as a potential bating agent. However, further studies are necessary to reduce the production cost for higher yield and commercialization.

This work analyzes a computational fluid dynamics (CFD) methodology based on ANSYS to investigate the 3 % and 4 % volume fraction alumina (Al2O3) nanofluids with base fluids FLiBe (LiF(67)-BeF2(33) (mol%)) and FLiNaK (LiF(46.5)-NaF(11.5)-KF(42) (mol%) through a double pipe heat exchanger. The purpose of the paper is to choose better candidates as secondary coolants in molten salt reactors for better thermodynamics performances and heat transfer characteristics. Six secondary coolants with and without nanofluids and fuel salt as primary coolants are driven through the inner and outer pipe. Later overall heat transfer coefficient, outlet temperatures and pressure drops of the fluids, and LMTD are calculated. Thus, this work eventually recommends the best candidate as a secondary coolant by CFD methodology using ANSYS-FLUENT 18.1.

Asiakkaan ohjausprosessi ja ohjauksen tuloksellisuus: Tapaustutkimus TE-toimiston ammatinvalinta- ja uraohjauksesta
Authors: Koivuluhta Merja
Published: June 2022

Tutkimuksen aiheena on nuoren asiakkaan ohjausprosessi ja ohjauksen vaikuttavuus lyhytkestoisessa ohjauksessa. Tutkimus on tapaustutkimus, jossa yhden ohjausprosessin tarkan kuvauksen ja analysoinnin avulla pyritään kehittämään dialogisen ohjauksen teoriaa ja käytäntöä. Aineistona ovat yhden asiakkaan ohjausprosessin tapaamisten äänitteet. Prosessi koostuu neljästä psykologin ja asiakkaan noin tunnin mittaisesta tapaamisesta. Dialoginen sekvenssianalyysi toimi sekä ohjausprosessin lähtökohtana olleen tapauskuvauksen perustana että aineiston analyysin välineenä. Analyysi osoitti, että ohjaajan prosessin alussa tekemä asiakaskuvaus fokusoi työskentelyn asiakkaan ydinongelmiin ja kannattelee ohjausprosessin etenemistä. Tapauskuvaus toimii ohjauksen yksilöllisen tuloksellisuuden arvioinnin välineenä. Lyhytkestoisessa ohjausprosessissa on mahdollista tukea toimijan havainnoivan suhteen kehittymistä omaan toimintaansa ja vaihtoehtoisen toimintatavan hahmottamista, vaikka toiminnan muutos jää lyhyen ohjausprosessin jälkeiseen aikaan.

Tutkimuksessa tarkasteltiin kahdessa peruskoulun monialaisessa opiskeluhuoltoryhmässä käytyjä keskusteluja oppilaiden hyvinvoinnin edistämisestä hyödyntäen subjektitieteellisen (Holzkamp 2013) ja systeemisen psykologian (Järvilehto 2009) käsitteistöä ja menetelmällisiä periaatteita. Keskusteluihin osallistui 30 eri ammattiryhmien ja tahojen toimijaa. Analysoimme käytyjä keskusteluja jatkuvan vertailun menetelmällä ja perusteluanalyysilla tunnistaen erilaisia tulkintoja opiskeluhuoltotyön tavoitteista ja peilaten näitä opiskeluhuoltotyölle lainsäädännössä ja opetussuunnitelmassa asetettuihin yleisiin tavoitteisiin. Tunnistimme aineistosta kolmenlaisia olosuhteita, joista ammattilaiset keskustelevat: 1) olosuhteet, joiden muuttaminen on vaikeaa, 2) olosuhteet, joita koetaan voitavan muuttaa oman ammattiryhmän yhteisenä toimintana ja 3) olosuhteet, joiden muuttamiseksi kytkeydytään yhteiseen toimintaan yli ammattirajojen. Tulosten mukaan ammattilaisten puheesta tunnistetut osallisten tavoitteet tai toimintaperusteet eivät juuri muutu keskustelun aikana. Pedagogisten ammattilaisten tulkinnat ja tavoitteet näyttivät määrittelevän keskustelun yhteistä suuntaa. Opiskeluhuollon ammattilaiset ja muut toimijat näyttivät eri tavoin sovittautuvan näihin tulkintoihin. Moniammatillisessa yhteistyössä ei aina pystytä hyödyntämään osallisten asiantuntemusta täysimääräisesti. Oppilashuollon ja ohjauksen tukena olevia moniammatillisen yhteistyön rakenteita on tarkasteltava kriittisesti ja kehitettävä.

Tutkimuksen tavoitteena oli selvittää opettajien valmiuksia, osaamista ja haasteita Move!-järjestelmän toteutuksessa ja oppilaiden toimintakyvyn tukemisessa. Tutkimuksessa hyödynnettiin ammatillisen sosiaalistumisen viitekehystä. Koettuja valmiuksia, osaamista ja haasteita verrattiin erilaisen liikuntapedagogisen koulutuksen suorittaneiden opettajien välillä. Aineisto kerättiin verkkokyselynä, johon vastasi yhteensä 359 opettajaa. Opettajista 75:llä (22,5 %) oli suoritettuna perusopetuksessa opetettavien aineiden ja aihekokonaisuuksien monialaiset opinnot (POM), 68:lla (20,4 %) liikuntapedagogiikan perusopinnot (PO), 42:lla (12,6 %) aineopinnot (AO) ja 148:lla (44,4 %) syventävät opinnot (SO). Tulosten mukaan opettajat kokivat osaavansa mittausten toteuttamisen hyvin, mutta tulosten pedagoginen hyödyntäminen oli vaatimattomampaa. Yksisuuntaisen varianssianalyysin tulokset osoittivat, että POM suorittaneilla osaaminen oli heikompaa Move!-järjestelmän toteuttamisessa ja oppilaiden toimintakyvyn tukemisessa. He kokivat myös enemmän haasteita mittausten toteuttamisessa kuin AO ja SO suorittaneet opettajat. Kuitenkaan yleispedagogisissa taidoissa, kuten motivoinnissa tai positiivisen ilmapiirin luomisessa ei eroavaisuuksia havaittu. Tulevaisuudessa opettajien perus- ja täydennyskouluttajien ja opetuksen järjestäjien tulisi painottaa mittaustulosten laajaa pedagogista hyödyntämistä.

Introduction: Tethered Cord Syndrome (TCS) is a condition that occurs due to spinal cord traction caused by the attachment of the spinal cord to the surrounding tissues. The incidence of TCS is quite rare, approximately 0.25 per 1,000 live births Case Presentation: We reported a 4-year-old female patient with a lump on her sacral region since birth which enlarged over time. The patient experienced intermittent fever for 1 month before hospital admission and constipation since infancy. Physical examination revealed a lump with a diameter of 6 cm on her sacral region with no neurological abnormality. Ultrasonography examination showed an anechoic lesion with multiple linear structures on supragluteal sinistra with a size of 2.2 x 2.5 x 2.1 cm. MSCT findings showed spina bifida at L5 until S2 level with features of lipomyelomeningocele and tethered cord started from L2 level. Bilateral hydronephrosis, hydroureter, and distended bladder (pine tree appearance) with the possibility of the neurogenic bladder were also found on MSCT examination. The patient underwent surgery to excise the lump and to release the tethered cord. Microscopic findings from excised mass showed a group of neuronal and glial cells, the syncytial sheet pattern of meningothelial cells, and foci of calcification which supported lipomyelomeningocele diagnosis. Conclusions: : Intensive follow-up care and observation must be carried out in children with spinal dysraphism because it may be associated with TCS which may be asymptomatic at an early stage.

Background: Gamma irradiation can cause DNA damage in single and double-strand breaks (SSBs & DSBs), especially in peripheral blood lymphocytes. Radiotherapy medical radiation workers can be exposed to gamma radiation related to their daily work. The comet assay is a sensitive method for analyzing DNA damage, especially SSBs. This study explores DNA damage in medical radiation workers’ peripheral blood lymphocytes as an adaptive response using the comet assay.Methods: Blood samples were obtained from four radiotherapy medical radiation workers as a case study (MRW) and two non-medical radiation workers as controls, and then irradiated with various doses of 0, 1, 1.5, and 2 Gy. Lymphocytes were isolated by histopaque and processed by comet assay on the slide under alkaline conditions. The imaging results were analyzed using the Casplab_1.2.3b2 software. The comet assay parameters observed were Tail Length (TL), % Tail DNA (T.DNA), Tail Moment (TM), and Olive Tail Moment (OTM). The one-way ANOVA method was used to analyze statistically between treatment groups. Results: Based on the study results, an increase in TL, T.DNA, TM, and OTM values in all samples was directly proportional to the increase in radiation dose. However, there was no significant difference (P > 0.05) between the MRW group and the control group on each parameter of the comet assay.Conclusions: From this study, it can be concluded that the level of DNA damage of lymphocyte cells as part of the adaptive response in the MRW and control groups was relatively similar after exposure at doses of 0, 1, 1.5, and 2 Gy.

Background: Nasopharyngeal cancer (NPC) is a malignant epithelial tumor located in the nasopharynx and is the most common head and neck malignancy. This study aimed to find and describe the profile of NPC patients who undergo radiotherapy at Dr. Hasan Sadikin General Hospital, Bandung.Methods: This study was a descriptive study conducted at the Department of Radiology of Dr. Hasan Sadikin General Hospital, Bandung. This study employed a total sampling method and was done by observing patients’ status/medical records from January 1, 2018, to December 31, 2019, which was registered based on the Hospital-Based Cancer Registry (HBCR). The inclusion criteria were all patients diagnosed with NPC and undergone radiotherapy.Results: There were 274 records (19.74%) included as NPC from 1,388 records. This cancer was more frequent in men (70.4%), in the age group of 45–54 years (35.0%), non-active smokers (58.8%), entrepreneurs (23.0%), and those who came from West Priangan (36.1%). The most common chief complaint was an enlargement of neck lymph nodes (55.1%) at stage IVB (42.8%). Histopathological findings were dominated by undifferentiated squamous cell carcinoma (WHO III) (74.4%). Most of the patients were treated with chemoradiation (64.3%).Conclusions: NPC could happen to anyone with different background. This study found it was more frequent in men than women (2.3:1), in the fourth and fifth decade of life, in entrepreneurs followed by housewives, and even in non-active smokers. It also could happen in children to the elderly. Most patients came with an enlargement of neck lymph nodes as their chief complaint in the advanced stage and need chemoradiation as their treatment.

Introduction: Breast cancer is the most common type and lethal cancer affecting women. Meanwhile, vinorelbine is one of the chemotherapy agents used for luminal and non-luminal breast cancer. Therefore, this study aims to determine the survival difference between patients with luminal and non-luminal subtype breast cancer treated with vinorelbine.Methods: This study was a retrospective cohort. Women with breast cancer treated with vinorelbine were classified based on estrogen receptor (ER), progesteron receptor (PR), human epidermal growth factor receptor-2 (HER-2) markers, and subtypes. The subjects were followed up to chemotherapy visits with vinorelbine recorded in the medical record. The survival analysis between subtypes was analyzed by the Kaplan-Meier curve.Results: : One hundred women were obtained with a mean age of 52.36 ± 10.45 years. Based on immunohistochemistry, 60% were ER-positive, 53% were PR positive, and 57% were HER-2- positive. Based on the subtype, 67% were luminal, while 33% were non-luminal. All subjects had a mean survival duration of 155.38 days (95% CI 128.05-182.71). The stratified survival analysis showed a significant difference in survival duration based on HER-2 marker and subtype. The subjects with HER-2 positive survived longer with a mean of 203.37 days (190.72–216.02) than those with HER-2 negative with a mean of 90.10 days (65.68-114.53) (p<0.001). In addition, the subjects with the luminal subtype survived longer with a mean of 174.84 (142.72-206.94) than those with non-luminal with a mean of 90.10 (65.68-114.53) (p = 0.04).Conclusion: There was a significant difference in survival duration between women with breast cancer treated with vinorelbine chemotherapy who were HER-2 positive, HER-2 negative, and luminal and non-luminal subtypes.
