Published: May 2022

This qualitative study principally aimed to discover how songs can be used to promote students' affective domain in listening class activities. One English teacher and twenty-five 8th-grade students of a public junior high school in Greater Aceh, Indonesia, were involved in this study. The data were collected through classroom observation. This present study followed Krathwohl, Bloom, and Masia’s (1973) five observation criteria of the affective domain framework. Subsequently, the teacher and four selected students were interviewed for additional data. The results demonstrated that songs have a positive impact on students' affective domain. Students become enthusiastic about learning listening skills. They listened well and remembered the title of the new song (receiving phenomenon); actively participated in the classroom activities (responding phenomenon); demonstrated their problem-solving ability by working together (valuing); and effective time management (organization). Despite their ability to cooperate in group activities, they had no self-reliance when working individually (internalizing values). However, the students agree that the classroom environment was more comfortable and enjoyable. The results of the study suggest that teachers should consider using songs to not only teaches the knowledge but also the culture associated with the song itself when it comes to teaching listening. Aside from the cognitive aspects, teachers should also maintain and track students' progress in the affective domain.

Authors: M. Amin Fakhrurrazi , Zulfitri Zulfitri
Published: May 2022

To prevent the spread of the coronavirus (Covid-19) and its pandemic, emergency remote teaching must be implemented. This has brought significant problems and difficulties for students due to this unusual circumstance, EFL students must learn to adapt their abilities. Because of the widespread use of technology in education, the quick transition to complete online learning necessitates some adjustment. EFL students must be able to handle online learning that is performed through technology integration and utilizing technological tools they have never used before in a short period of time. In response to emergency remote teaching, this study examined how engaged EFL students are, as well as their perceptions of such engagement. One hundred ninety-one students from four state Islamic universities in Aceh filled out an online questionnaire adapted from McColskey (2012). Both descriptive and thematic methods were used to analyze the data. EFL students demonstrated their level of engagement in all three categories of engagement: behavioral, emotional, and cognitive engagement. Positive responses and feelings of satisfaction were shown during emergency remote teaching. It indicates that EFL students have a better grasp of how to use technology in education. It is essential to constantly enhance their skills and have enough equipment and infrastructure to facilitate online learning.

Introduction: Global evidence on the epidemiology of prevalent diving-related injuries (DRI) different from decompression sickness (DCS) and other fatalities is lacking. This study aimed to perform a comprehensive review of DRIs in the year-period between 2010-2020 in a non-hyperbaric tertiary hospital in the Spanish Mediterranean coast, in addition to identifying patient risk factors for severe middle ear barotrauma. Methods: The study was conducted via a retrospective review of medical records during a 10-year period (2010- 2020) at the University and Polytechnic Hospital La Fe (UPHLF) of Valencia. We performed a case-control study recruiting controls through an online survey to identify independent predictors for severe middle ear barotrauma. Results: A total of 68 patients with DRI attended the emergency department of our tertiary referral hospital. Barotrauma accounted for more than 80% of DRI, followed by unrecognized DCS and animal-related injuries. Most patients required neither hospital admission nor surgery; appropriate treatment could be carried out largely on an outpatient basis. The presence of subsequent sequelae was minimal. Previous presence of significant ear, nose and throat (ENT) comorbidities (OR 3.05 – CI 95% 1.11 – 8.35), and older age (OR of younger age 0.94 – CI 95% 0.91 – 0.98) were identified as independent risk factors for severe middle ear barotrauma, with an acceptable discrimination capacity (AUC 0.793, 95% CI 0.71 – 0.87). Conclusions: The incidence of DRI may be higher than previously thought, and the need to know their epidemiology, their associated morbidity, and the deficiencies of the diving management system is becoming steadily important in order to develop prevention, diagnostic and therapeutic protocols in non-hyperbaric hospitals of these regions.

Background: Changes in barometric pressure conditions that occur during flying and diving under hyperbaric oxygen conditions were found to influence the retention of dental restorations. Aim: This experimental laboratory study aimed to evaluate the bond strength of glass fiber posts after being cemented with self-adhesive resin cement (RelyX™ Unicem, 3M ESPE) and self-etch adhesive resin cement (RelyX™ Ultimate, 3M ESPE) under normal atmospheric pressure and hyperbaric pressure cycles that simulate diving conditions. Methods: A total of 40 extracted, single-rooted mandibular premolars were treated endodontically and randomly divided into two groups according to the cements used for fiber post cementation. Each group was further randomly divided into two equal subgroups that were subjected to normal atmospheric pressure conditions and a simulated hyperbaric condition in a hyperbaric chamber. The pull-out bond strength of fiber posts was tested using a universal testing machine. Data were analyzed using one-way analysis of variance with the Tukey post-hoc test (p<0.05). Results: At normal atmospheric pressure the mean value of the pull-out bond strength of RelyX Ultimate cement was significantly higher than that of RelyX Unicem cement. At hyperbaric pressure condition no significant difference was found between the mean values of the pull-out bond strength of RelyX Ultimate and RelyX Unicem cement. Conclusion: Hyperbaric pressure cycles demonstrated improved pull-out bond strength of glass fiber posts in RelyX Unicem cement but did not have significant effect on pull-out bond strength in RelyX Ultimate cement. Both resin cements have similar pull-out bond strength of glass fibers post after simulated dives.

Introduction: Inner ear decompression sickness (IEDCS) is a condition from which only a minority of patients recover completely, the majority ending up with mild to moderate residual symptoms. IEDCS has been reported after deep technical dives using mixed breathing gases, and moderate recreational dives with compressed air as the breathing gas. Considering this and the high proportion of technical diving in Finland, a comparison between IEDCS cases resulting from technical and recreational dives is warranted. Methods: This is a retrospective examination of IEDCS patients treated at Hyperbaric Center Medioxygen or National Hyperbaric Centre of Turku University Hospital from 1999 to 2018. Patients were included if presenting with hearing loss, tinnitus, or vertigo and excluded if presenting only with symptoms of middle ear or cerebellar involvement. Patients were divided into technical and recreational divers, based on incident dive. Results: A total of 89 (15.6%) of all DCS patients presented with IEDCS, two-thirds treated during the latter decade. The most common predisposing factors were consecutive days of diving (47.2%), multiple dives per day (53.9%), and factors related to an increase in intrathoracic pressure (27.0%). The symptoms were cochlear in 19.1% and vestibular in 93.3% of cases, symptoms being more common and severe in technical divers. Complete recovery was achieved in 64.5% of technical and 71.4% of recreational divers. Conclusion: The incidence of IEDCS in Finland is increasing, most likely due to changing diving practices. A comprehensive examination should be carried out after an incident of IEDCS in all cases, irrespective of clinical recovery.

This study aimed to compare the efficacy of two commonly used therapeutic pressures, 2.0 atmospheres absolute (ATA) versus 2.2 ATA, applied in hyperbaric oxygen (HBO2) therapy for sudden sensorineural hearing loss (SSNHL). We retrospectively reviewed the clinical records of 160 SSNHL patients treated by typical therapy or additional HBO2 therapy with pressure 2.0 or 2.2 ATA at Yijishan Hospital, the First Affiliated Hospital of Wannan Medical College, from February 2018 to May 2020. The pure-tone threshold audiometry results pre- and post-treatment were compared across three groups. In the range of frequencies 250-500 Hz, P2.0 (20.92±26.11 dB, p=0.047) and P2.2 group (20.47±21.54 dB, p=0.012) both acquired higher hearing gain compared to the control group (11.94±23.32 dB). While in the range of frequencies 1,000-2,000 Hz, only the P2.2 group showed significant improvement of the hearing gain compared to the control group (19.70±21.13 dB vs.10.56±25.24 dB, p=0.015). In the range of frequencies 4,000-8,000, both the P2.0 and P2.2 groups failed to reach the desired effect. Our results suggest that the therapeutic effect is associated with HBO2 therapeutic pressure when applying HBO2 treatment combined with standard medical therapy. Within the range of appropriate pressure, the higher pressure, which means higher partial pressure of oxygen, has better therapeutic efficacy for SSNHL.

Inner ear decompression sickness (IEDCS) is a rare diving complication that presents with vestibular dysfunction, cochlear dysfunction, or a combination of both. While scuba diving is a known cause, no cases have been reported in the occupational hyperbaric setting. We present the case of a 55-year-old man who developed IEDCS after working as a hyperbaric multiplace chamber inside tender. The patient was treated with seven sessions of hyperbaric oxygen therapy, resulting in resolution of the majority of his symptoms. This case illustrates a potential occupational hazard of working in a hyperbaric chamber and demonstrates successful treatment with hyperbaric oxygen therapy.

Para o infliximabe foi observada queda no consumo (-69 pacientes/ano), e impacto crescente de 4% nos recursos do CEAF. O rituximabe teve a menor demanda (745 paciente/ ano), com expansão de 693% e crescimento no dispêndio em 414%. Conclusões: Observou-se a evolução do gasto, com a aquisição de medicamentos biológicos para AR, com significativo impacto econômico para o SUS com a ampliação da oferta de tratamento.
Artigo de revisão: Uso da ATS na tomada de decisões nas análises clínicas - uma revisão sistemática
Authors: Dias Tamiris , Oliveira Seixas Carvalho Magda
Published: May 2022

Introdução: A avaliação de tecnologias em saúde (ATS) de dispositivos médicos é desafiadora. Apesar de ser uma área com tecnologias que podem ser dispendiosas para o sistema de saúde, pouco se fala sobre a ATS em relação a equipamentos e reagentes de uso laboratorial. Objetivos: Identificar o que foi publicado na literatura científica, nos últimos dez anos, sobre o uso da ATS na tomada de decisões nas análises clínicas. Métodos: Consiste em uma revisão sistemática na qual foram utilizadas as bases de dados PubMed e BVS/Lilacs. Após a triagem inicial, foi feita a avaliação dos textos completos, seguida da avaliação dos riscos de viés e discussão dos resultados. Resultados: 15 artigos foram incluídos nesta revisão sistemática. 80,0% foram relatórios de ATS e 20,0% foram artigos originais; 86,7% se concentraram entre 2014 e 2017; e o Reino Unido foi o país com dados mais publicados (66,7%). Essa revisão apresentou uma alta heterogeneidade em termos de tecnologia avaliada; a única tecnologia que foi avaliada em mais de um trabalho foi o ensaio de liberação de interferon-gama (IGRA). Três trabalhos não apresentaram tecnologias para comparação. Vários documentos incluídos concluíram não terem encontrado evidências suficientes ou os dados se mostraram com alto grau de incerteza para fazer alguma recomendação. Conclusões: A ATS na área laboratorial é um nicho ainda pouco explorado, e muito pode ser feito visando a melhoria do serviço das análises clínicas.
Avaliação de tecnologias para doenças raras e judicialização: relação entre as demandas judiciais e as ações da Comissão Nacional de Incorporação de Tecnologias no Sistema Único de Saúde (CONITEC)
Authors: Beutel José
Published: May 2022

O presente estudo teve como objetivo descrever, no período de 2016 a 2020, a evolução dos gastos do Ministério da Saúde para o cumprimento de determinações judiciais que buscavam o direito à saúde, com enfoque nas doenças raras, e identificar as tecnologias avaliadas pela Conitec. Por meio de análise documental, foram considerados os valores gastos, a relação de medicamentos que mais despenderam recursos, as tecnologias avaliadas pela Comissão, as deliberações emitidas pela Conitec e a relação entre essas avaliações e as determinações judiciais. Verificou-se que, apesar da Conitec realizar um rigoroso processo de Avaliação de Tecnologias em Saúde (ATS) e direcionar esforços para tornar acessíveis suas ações e recomendações, parece haver uma falta de engajamento dos operadores do Direito para entender como e porque ocorre a incorporação de tecnologias em saúde ao Sistema Único de Saúde (SUS). Semelhantemente, insinuam-se certo distanciamento e ausência de interlocução entre essas duas instâncias. Diante da especificidade do tema – que não requer apenas o saber jurídico, mas também o do campo da ATS –, entende-se como possível solução a aproximação entre Poderes Executivo e Judiciário, para que compartilhem conhecimento e trocas de experiência e a judicialização possa servir como instrumento de garantia de direitos postos na Constituição e normas infraconstitucionais.
Did Accrual Earnings Management Decline and Real Earnings Management Increase Post-SOX? A Re-Examination Over an Extended Post-SOX Period and A Closer Look at REM-AEM Substitution
Authors: Pincus Morton , Wu Shijia , Hwang Jasper
Published: May 2022

A widely cited paper, Cohen, Dey, and Lys (2008, hereinafter CDL), examines accrual (AEM) and real earnings management (REM) pre- and post-Sarbanes Oxley and provides evidence that, in the period immediately following SOX, accruals management declined and was substituted by REM. We re-visit CDL and ask whether CDL's main results extend to recent periods and hold using updated research design choices. We find AEM declines in the period immediately after SOX, but the results are sensitive to some design choices. We also find AEM generally declines over our entire extended post-SOX period, suggesting that the components of SOX were largely successful in constraining AEM. REM is higher post-SOX but with an insignificant trend over the entire extended post-SOX period. Additionally, the results indicate REM and AEM behave as substitutes in the period preceding SOX, but the substitution effect significantly weakens post-SOX.
Do High-Quality Auditors Improve Non-GAAP Reporting?
Authors: Feng Zhuoan , Francis Jere R. , Shan Yaowen , Taylor Stephen L.
Published: May 2022

Prior research finds that clients of high-quality auditors report higher-quality GAAP earnings. We extend this research to investigate whether auditor quality is associated with the quality of voluntarily disclosed non-GAAP earnings measures. Using a sample of Australian firms disclosing annual non-GAAP metrics, we find that clients of high-quality auditors are more likely to voluntarily disclose non-GAAP earnings numbers. However, clients of high-quality auditors make adjustments in calculating non-GAAP earnings (non-GAAP exclusions) that are less predictive of future earnings and less value relevant than those of other firms. These results indicate that their adjustments are of higher quality. We also find similar results for U.S. firms using a sample of quarterly non-GAAP earnings disclosures. Overall, our evidence indicates that commonly used indicators of audit quality for GAAP reporting are positively associated with the quality of voluntarily disclosed non-GAAP earnings measures.

Published: May 2022

Transient insulin deprivation with concurrent hyperglucagonemia is a catabolic state that can occur in type 1 diabetes. To evaluate glucagon’s catabolic effect in the setting of its glucogenic effect, we measured the regional exchanges of amino acid metabolites (amino-metabolites) across muscle and splanchnic beds in 16 healthy humans during either somatostatin followed by glucagon or saline infusion alone. Despite a twofold or greater increase in the regional exchange of amino-metabolites by glucagon, whole-body kinetics and concentrations of amino acids (AA) remained stable. Glucagon increased the splanchnic uptake of not only gluconeogenic but also essential (EAA) AA while increasing their release from the muscle bed. Regional tracer-based kinetics and 3-methylhistidine release indicate that EAA release from muscle is likely caused by reduced protein synthesis rather than increased protein degradation. Furthermore, many metabolites known to affect insulin action and metabolism were altered by hyperglucagonemia including increase in branched-chain AA and keto acids of leucine and isoleucine in arterial plasma. Further, an increase in arterial concentrations of α-aminoadipic acid arising from increased conversion from lysine in the splanchnic bed was noted. These results demonstrate that hyperglucagonemia during hypoinsulinemia increases net muscle protein catabolism and substantially increases the exchange of amino metabolites across splanchnic and muscle beds.
Extreme output power emitted by commercial laser pointers in Greece: A solely local or a global issue?
Authors: Petri Aspasia , Karabetsos Efthymios
Published: May 2022

Although several countries have enacted legislation that prohibits the commercial distribution of laser pointers, high-power laser pointers are abundantly available on the market. The Greek Atomic Energy Commission (EEAE) investigated the compliance of laser pointers with the laser radiation safety limits in order to apply risk management actions in Greece. Compliance was assessed based on the laser pointer labeled data and in-house optical measurements. Laser pointers were purchased randomly from domestic physical marketplaces. Output power measurements revealed the risk of overexposure compared to the lasers' radiation safety limit values. Measured values also exceeded the output power values claimed on the laser pointer labels; hence, they may pose an unexpected more severe hazard than stated. Spectral analysis revealed an additional emission wavelength by the green laser pointers. All the inspected laser pointers declared “compliance with 21 CFR” and were labeled according to the U.S. 21 CFR 1040.1, although all consumer products available on the Greek market should comply with the relevant EU Directives, harmonized standards, and national legislation. These local findings adhere to a global issue—the unambiguous exposure of nonexpert users to high-power laser pointers that should not be commercially available. Overexposure to laser pointer radiation suppresses national borders as markets are not locally constrained, and laser technology continues to advance. The introduction of a universal laser safety language and a universal regulatory framework for laser pointers might facilitate product safety, international trade, and users' safety. EEAE runs social media campaigns to raise public awareness of laser pointer risks, using specifically designed infographics.

Authors: Utami Putri Novia
Published: May 2022

Kebutuhan masyarakat Indonesia akan listrik saat ini sangatlah tinggi, termasuk Desa Bumi Dipasena Agung, Rawajitu Timur, Tulang Bawang, Lampung. Di Desa Bumi Dipasena Agung hanya sebagian rumah saja yang memiliki aliran listrik dan tersambung dengan Perusahaan Listrik Negara (PLN). Salah satu upaya masyarakat yang tidak dapat mengaliri listrik dari PLN adalah memanfaatkan energi matahari. Energi matahari dimanfaatkan melalui panel surya dan menghasilkan energi listrik dengan sistem panel surya untuk skala rumah tangga atau Solar Home System (SHS). Pemasangan panel surya sekarang ini masih bersifat statis atau hanya tegak lurus dengan arah sinar matahari, dimana posisi ini kurang optimal dalam proses penyerapan energi matahari, untuk menghasilkan penyerapan panel surya yang optimal maka dirancanglah alat solar tracking system. Alat ini bekerja menggunakan microcontroller Arduino UNO sebagai pusat kontrolnya dan dipasang sensor Light Dependent Resistor (LDR), dimana sensor Light Dependent Resistor (LDR) akan membaca intensitas cahaya yang masuk dari matahari dan actuator dapat bergerak mengikuti arah datang cahaya matahari. Pada pengujian dengan solar tracker rata – rata harian yang dihasilkan panel surya yaitu tegangan 19,94 Volt, arus 5,07 A, dan daya 88,69 Watt sedangkan, pengujian tanpa solar tracker rata – rata harian yang dihasilkan panel surya yaitu tegangan 18,7 Volt, arus 3,77 A, dan daya 70,9 Watt dan dapat dilihat pada grafik penyerapan harian tegangan dan arus menggunakan solar tracker jauh lebih optimal dibandingkan tanpa solar tracker.

RANCANG BANGUN SISTEM PROTEKSI OVERHEATING MESIN DAN PEMANTAU TEGANGAN AKI PADA MOBIL
Authors: Ahmad Yuvi Utomo
Published: May 2022

Abstract -- Overheating is one of the causes of damage or decreased performance on the vehicle. This can occur due to a lack of water in the radiator or a radiator leak. Generally, overheating occurs in vehicles manufactured before 2000 because they do not have protection or warning in case of excessive temperature. Vehicles with production years before 2000 usually only have a temperature indicator in the form of a pointer with a scale. In addition to overheating, the voltage on the battery cannot be monitored due to the absence of a battery voltage reader so that the battery experiences under-voltage or overvoltage caused by damage to the charging system in the battery. Based on these problems, a tool is made to prevent overheating and prevent damage to the battery. In this tool, the DS18b20 sensor is used to determine the temperature that occurs in the vehicle engine, while the battery voltage information is obtained using a voltage divider circuit. The results of the temperature and voltage sensors are processed using the Arduino Nano Microcontroller to obtain information about the engine temperature and battery voltage. The processing results are displayed using an OLED LCD and the output is connected to two relays, one relay for automatic fans and one relay for vehicle ignition. The results showed that this tool can turn on and turn off the fan automatically, and can cut off the ignition of the vehicle based on the temperature of the radiator water. This tool provides a warning if the battery voltage is above or below the normal voltage. With this tool, overheating of the engine and damage to the battery can be prevented.

To describe the loading time effect on the viscoelastic properties of asphalt pen 80/100 with varying content of pure Asbuton with dif-ferent time sweeps, the basic rheological characteristics and mechanical rheological properties were measured with a dynamic shear rheometer in the laboratory. Complex shear modulus (G*) decreased, phase angle values increased, and strain value increased with increasing load-ing time. Vehicle speed and loading frequency were inversely proportional to loading time; thus, it can be concluded that increasing the vehicle speed and increasing the vehicle loading frequency will cause an increase in G*, decrease in phase angle, and decrease in strain. Bitu-men stiffness modulus (E *) was inversely proportional to the increase in loading time. Perma-nent deformation damage criteria, both before and after mechanical rheology test (RTFOT), showed that the shorter the loading time, the stronger the bitumen is in resisting permanent de-formation damage. Based on fatigue cracking criteria, all combinations of loading time and Asbuton content fulfill the statutory requirements for fatigue cracking resistance. Abstrak: Waktu pembebanan (Time Sweep) merupakan salah satu variabel utama yang mempengaruhi kinerja material aspal yang berkaitan dengan ketahanan terhadap pembebanan pada perkerasan jalan. Untuk dapat memperoleh gambaran dari pengaruh variasi waktu pem-bebanan terhadap sifat reologi visco-elastic aspal pen 80/100 dan Asbuton murni maka dil-akukan pengujian sifat reologi dasar dan sifat reologi mekanistik dengan alat Dynamic Shear Rheometer dengan beberapa variasi kadar Asbuton murni. Hasil peneitian menunjukkan pen-ingkatan waktu pembebanan menyebabkan penurunan nilai complex shear modulus (G*), pen-ingkatan nilai phase angle, dan peningkatan nilai regangan. Jika hasil ini dikaitkan dengan ke-cepatan kendaraan dan frekuensi pembebanan yang berbanding terbalik dengan waktu pem-bebanan, maka dapat disimpulkan bahwa peningkatan kecepatan kendaraan dan bertambahnya frekuensi pembebanan kendaraan akan menyebabkan peningkatan nilai G*, penurunan nilai phase angle, dan penurunan nilai regangan pada sampel. Dalam tinjauan modulus kekakuan bi-tumen diperoleh peningkatan waktu pembebanan menyebabkan penurunan modulus kekakuan bitumen. Dalam kajian kriteria kerusakan Permanent Deformation baik pada kondisi original maupun pada kondisi setelah RTFOT dapat disimpulkan bahwa semakin kecil waktu pem-bebanan maka semakin kuat bitumen tersebut dalam menahan kerusakan Permanent Defor-mation. Sedangkan, dalam kajian kriteria kerusakan Fatigue Cracking dapat disimpulkan bah-wa seluruh kombinasi waktu pembebanan memenuhi persyaratan jika dilakukan tinjauan ketahanan material terhadap fatigue cracking.

Abstract: Traffic jam at signalized intersections, are a problem generally occurred in Indonesian cities, including Mataram City, Lombok Island, West Southeastern Nusa Province. Such problem is affected by the increasingly large number of vehicles and the limited road paths. Therefore, the objectives of the study are to examine the intersection performance of Gomong and compare the results of analysis based on manual calculation using MKJI and using KAJIsoftware. Data were collected through recording and direct measurement in the site of the study. The data collected were then processed in laboratory to examine the intersection performance. The signalized inter-section performance was analyzed using MKJI 1997 method and given solutions to solve the prob-lem related to the intersection performance. The solution used to solve the problem was analyzed for the performance in the next 5 years. To compare the results of analysis by using KAJI soft-ware, the calculation was carried out in the existing condition of an intersection by using alterna-tive solutions used. The results of analysis show that the signalized intersection performance of Gomong was not in accordance with the standards determined in MKJI 1997 (Showed by value of DS 1.556 >standard 0.75). The comparison using KAJI software shows that the basic parameters of calculation do not significantly different (1.18% for existing condition and 1.01%Abstrak: Kemacetan lalu lintas merupakan masalah yang umum terjadi di kota-kota besar di In-donesia, termasuk Kota Mataram yang terletak di Pulau Lombok, Nusa Tenggara Barat.Kemacetan lalu lintas dipengaruhi oleh semakin banyaknya jumlah kendaraan dan terbatasnya ruas jalan. Oleh karena itu, tujuan dari penelitian ini sendiri adalah untuk mengetahui kinerja simpang empat Go-mong dan membandingkan hasil analisis antara hitungan manual MKJI dan software KAJI. Pengumpulan data dilakukan dengan cara perekaman dan pengukuran langsung di lokasi penelitian. Data yang dikumpulkan kemudian diolah kembali di laboratorium untuk mengetahui kinerja simpang.

Music is an art that permeates every human society. It is used for such diverse
social purposes as ritual, worship, coordination of movement, communication, or
entertainment. There are no limits to music as it can move freely in space through sound
waves, radio, cinema, television, and the new digital technologies. Music is directly
related to subcultures in that cultural identities and lifestyles can be mediated
through music. This article aims to use the development of music scenes such as
psychobilly to establish a link between music, subcultures, globalization, and the
global-local dialectic.
Mentoring Students of Disadvantaged Background in Hungary — “Let’s Teach for
Hungary!” as an Equitable Intervention in the Public School System

The introductory study aims to give an insight into the Hungarian educational
system and a mentor program aiming to facilitate development in social mobility in the
country. In the Hungarian context of education, the concept of equality and equity is a
current phenomenon that influences students of underprivileged families. In Hungary,
among students living in the countryside, the intersectionality of disadvantages is
observed. Several regions of the country have features of unemployment and low
education. Thus, students from underprivileged families face a deficit of capital when
entering and proceeding into the educational system. The situation is further
complicated for the largest Hungarian minority, the Roma community, who face ethnic
biases and misbeliefs, thus creating the cumulation of disadvantages. For students to
overcome their difficulties, equitable interventions are needed. International and
Hungarian literature stress the importance of developing positive psychological capital
for students to become resilient. Peer-mentoring is observed as a tool to help
facilitate individual changes. The study focuses on the framework of a Hungarian
national peer-mentoring program called "Let's Teach for Hungary!" which aims
to help primary school students (aged 11-15) with the help of university students. The
theoretical analysis introduces the program and its goals. With the help of previous
research conducted on the mentoring program, the study synthesizes the positive outcomes
of the intervention. The research highlights the importance of equitable changes in
public education and reveals the Hungarian status quo and its alternative solutions. The
study creates a basis for continuing research that can open international discussion on
best practices on the topic.
Raytheon Technologies Corporation: An Analysis of Leadership, Ethics, and Social
Responsibility

The purpose of this analysis is to examine Raytheon Technologies Corporation (RTC)
in the context of its leadership structure, ethical issues and practices, stakeholder
relationships, and position within the social responsibility realm. Undertaking an
analysis of an aerospace and defense company such as RTC is perhaps timelier than ever.
We live in a world of increasing global competition and confrontation. Simultaneously,
we are experiencing unprecedented technological development. Combined, this has created
a situation where the boundaries of conventional warfare have been redrawn. The
questions of what appropriate offensive and defensive tactics are and how governments,
and increasingly private sector companies, utilize new technology to achieve superiority
do not have definitive answers. RTC is one of the largest aerospace and defense
companies in the world operating in this new age. Therefore, examining RTC in terms of
its leadership practices, ethical positions, and social responsibility efforts will help
to illuminate how both the company and society are working through these unchartered
waters.
The Operation Successful, But the Patient Died. The Gradual Elimination of the
Central European Peasantry in the Light of Globalization and Interwar Processes

In terms of “depeasantisation," it was with the EU accession in 2004 when
Central Europe – including Hungary – reached the stage where England had already arrived
in the 18th and Germany in the 19th century. The gradual disappearance of the peasantry
in the continent is doubtless in connection with the tendencies of globalization, a
phenomenon that could not be stopped even by the authoritarian regimes of the interwar
period – the time period examined by the dissertation. However, in a latent way, the
question had already arisen at the time: is peasantry necessary at all? Nevertheless, as
a consequence of the defeat in World War I, there were important national political
arguments for the preservation of peasantry in the region, together with the rise of
peasant ideologies. After 1945 – as Barrington Moore, the ideologist of the Cold War,
pointed out – the huge peasant masses meant the precondition for not only the creation
of fascism but also for Eastern European socialism. Therefore, many problems had to be
swept under the carpet. But the issue can be better understood once it is examined along
the “development slope." In this aspect, many experts in new comparisons drew
attention to the key role of Germany. Following the footsteps of the Canadian historian
Scott M. Eddie, the author of this article compares the agrarian societies of two areas
dominated by large estates, Pomerania and Somogy county, with a special focus on the
significance of identity. The research questions were the following: what were the
chances of the peasantry in those areas in the grip of modernity and large estates? To
what extent had this process altered identity? In order to map the latter
methodologically, the study required a wide interdisciplinary examination.
