Authors: Gökdemir Özden , Özkan Bayrakçı Nurşah , Aygün Olgu , Hoedebecke Kyle 
Published: April 2021

Abstract

Objectives
In 2018, Harvard University provided a 10-week online course titled “Improving Global Health: Focusing on Quality and Safety” as using Massive Online Open Courses (MOOCs) web-based platform. The course was designed for those who care about health and healthcare and wish to learn more about how to measure and improve that care – for themselves, for their institutions, or for their countries. The goal of this course was to provide visual and written education tools for different countries and different age groups. In respect to the aim of this study is to evaluate the impressions and benefits of group learning activity and educational needs after this “Improving Global Health” courses experience with an online survey among the participants.

Methods
Sixty-six family medicine practitioners and trainees who were among the participants of the course were the universe of the study. These young General Practitioners/Family Physicians (GPs/FPs) from different countries were organized among themselves to follow the course as a group activity. Two weeks after the course, an online survey was sent to all the participants of this group activity.

Results
Twenty-eight out of 66 participants (42.4%) completed the survey and provided feedback on their perspectives and experience. Most of them were female (70.4%), and have not attended any MOOC course before (63%). This international group achieved a completion rate of approximately 65% by the deadline and nearly 90% including those finishing afterward. The majority felt that the group activity proved beneficial and supportive in nature.

Conclusions
Well-structured, sustainable e-learning platforms will be the near futures’ medical learning devices in a world without borders. Future studies should further explore facilitators and barriers among FPs for enrolling and completing MOOCs. Furthermore, there is a need to evaluate how these group-learning initiatives may help participants incorporate lessons learned from the course into their daily practice.
Film cooling characteristics on a grooved surface with different injection orientation angles
Authors: Yang Peng , Li Guangchao , Zhu Jianyong 
Published: April 2021

Abstract
The film effectiveness was investigated on a grooved surface with the injection orientation angles of 30°, 90°, and 150° at the blowing ratios of 0.5, 0.8, 1.1, and 1.4. The injection orientation angle and the groove on the surface caused the effect of the various and irregular shaped hole injection due to the different orientation injection. The results showed that the new phenomenon of film effectiveness distributions was found on the grooved surface compared with the flat plate case. Film effectiveness distributions for the β = 30° were found to be the discontinuous strips. The surface averaged film effectiveness with the orientation angle of 30° was found to decrease with the increase of the blowing ratio. Additionally, the reverse trend was observed with the orientation angle of 150°. The film effectiveness with the orientation angle of 90° only slightly changed with the increase of the blowing ratio.
Life assessment of a high temperature probe designed for performance evaluation and health monitoring of an aero gas turbine engine
Authors: George Benny , Muthuveerappan Nagalingam 
Published: April 2021

Abstract
Temperature probes of different designs were widely used in aero gas turbine engines for measurement of air and gas temperatures at various locations starting from inlet of fan to exhaust gas from the nozzle. Exhaust Gas Temperature (EGT) downstream of low pressure turbine is one of the key parameters in performance evaluation and digital engine control. The paper presents a holistic approach towards life assessment of a high temperature probe housing thermocouple sensors designed to measure EGT in an aero gas turbine engine. Stress and vibration analysis were carried out from mechanical integrity point of view and the same was evaluated in rig and on the engine. Application of 500 g load concept to clear the probe design was evolved. The design showed strength margin of more than 20% in terms of stress and vibratory loads. Coffin Manson criteria, Larsen Miller Parameter (LMP) were used to assess the Low Cycle Fatigue (LCF) and creep life while Goodman criteria was used to assess High Cycle Fatigue (HCF) margin. LCF and HCF are fatigue related damage from high frequency vibrations of engine components and from ground-air-ground engine cycles (zero-max-zero) respectively and both are of critical importance for ensuring structural integrity of engine components. The life estimation showed LCF life of more than 4000 mission reference cycles, infinite HCF life and well above 2000 h of creep life. This work had become an integral part of the health monitoring, performance evaluation as well as control system of the aero gas turbine engine.

Published: April 2021

Abstract
Reducing the carbon footprints of aerial transportation became a major target for both industries and academia. Various solutions have been proposed to develop cleaner alternative methods for green transportation. Full electric, hybrid electric, and turboelectric propulsion system architectures intend to reduce greenhouse gas emissions and fuel consumption of today’s aero gas turbine engines. In this study, a turboelectric propulsion system, which is considered as the most promising technology for future aviation is selected for modelling and simulation. As the main power supply, a high fidelity mathematical model of GE T700 turboshaft engine is constructed in MATLAB/Simulink to emulate the technology of today. Selected aero gas turbine’s mathematical model is combined with NASA’s Baseline electrical power distribution architecture which is firstly designed for N-3X turboelectric aircraft. MATLAB/Simulink model is utilized to analyses a single-engine operational scenario of twin-engine aircraft which is a major design consideration due to single-engine failure. Power requirements, distribution percentages, preliminary power assessment for power electronic systems and nominal power capacities of each electrical unit of a turboelectric propulsion system are obtained using GE T700 as the main power supply.

Published: April 2021

Abstract
The present study investigates the effect of chevron with tab (Tabbed chevron) fixed at the exit of the co-flowing primary nozzle on the mixing characteristics in subsonic and sonic jets. The experiment was conducted for the jet Mach number 0.6 and 0.8. The centerline Mach number decay was calculated for all these jet Mach numbers for the co-flow baseline nozzle, nozzle with chevrons and tabbed chevron (primary flow) nozzle respectively. It was found that tabbed chevron was effective in reducing the potential core length by 88.23% as compared to the chevron nozzle with baseline nozzle. The radial profile also shows that the mixing enhancement by tabbed chevron is better than chevron nozzle.
Natural frequency analysis of a functionally graded rotor-bearing system with a slant crack subjected to thermal gradients
Authors: Bose Arnab , Sathujoda Prabhakar , Canale Giacomo 
Published: April 2021

Abstract
The present work aims to analyze the natural and whirl frequencies of a slant-cracked functionally graded rotor-bearing system using finite element analysis for the flexural vibrations. The functionally graded shaft is modelled using two nodded beam elements formulated using the Timoshenko beam theory. The flexibility matrix of a slant-cracked functionally graded shaft element has been derived using fracture mechanics concepts, which is further used to develop the stiffness matrix of a cracked element. Material properties are temperature and position-dependent and graded in a radial direction following power-law gradation. A Python code has been developed to carry out the complete finite element analysis to determine the Eigenvalues and Eigenvectors of a slant-cracked rotor subjected to different thermal gradients. The analysis investigates and further reveals significant effect of the power-law index and thermal gradients on the local flexibility coefficients of slant-cracked element and whirl natural frequencies of the cracked functionally graded rotor system.
Sexual incentive delay in the scanner: Sexual cue and reward processing, and links to problematic porn consumption and sexual motivation
Authors: Markert Charlotte , Klein Sanja , Strahler Jana , Kruse Onno , Stark Rudolf 
Published: April 2021

AbstractBackground and aimsThe use of pornography, while unproblematic for the majority, can grow into addiction-like behavior which in its extreme form is labeled as compulsive sexual behavioral disorder in the ICD-11 (WHO, 2018). The aim of this study was to investigate the addiction-specific reactivity to cues in order to better understand underlying mechanisms in the development of this disorder.MethodsWe have used an optimized Sexual Incentive Delay Task to study brain activity in reward associated brain areas during an anticipation phase (with cues predicting pornographic videos, control videos or no videos) and a corresponding delivery phase in healthy men. Correlations to indicators of problematic pornography use, the time spent on pornography use, and trait sexual motivation were analyzed.ResultsThe results of 74 men showed that reward-related brain areas (amygdala, dorsal cingulate cortex, orbitofrontal cortex, nucleus accumbens, thalamus, putamen, caudate nucleus, and insula) were significantly more activated by both the pornographic videos and the pornographic cues than by control videos and control cues, respectively. However, we found no relationship between these activations and indicators of problematic pornography use, time spent on pornography use, or with trait sexual motivation.Discussion and conclusionsThe activity in reward-related brain areas to both visual sexual stimuli as well as cues indicates that optimization of the Sexual Incentive Delay Task was successful. Presumably, associations between reward-related brain activity and indicators for problematic or pathological pornography use might only occur in samples with increased levels and not in a rather healthy sample used in the present study.
Theoretical conceptualisations of problematic exercise in psychometric assessment instruments: A systematic review
Authors: Sicilia Álvaro , Paterna Adrian , Alcaraz-Ibáñez Manuel , Griffiths Mark D. 
Published: April 2021

AbstractBackground and aims: The aim of the present systematic review was to identify psychometric tools developed to assess problematic exercise in order to identify and compare their theoretical conceptualisations on which they are based. Methods: A systematic literature search was conducted in the electronic databases Web of Science, Scielo, PsychINFO, PsycTEST and SCOPUS from their inception to January 2020. Results: Seventeen assessment instruments met the eligibility criteria to be included in the present review. The instruments were classified according to their conceptualisation into five groups: (i) problematic exercise as an end of an exercise continuum, (ii) problematic exercise as a means of regulating body size and weight, (iii) problematic exercise as dependence, (iv) problematic exercise as a behavioural addiction and (v) no clear conceptualisation. Discussion: The results suggest that the conceptualisations of the assessment instruments have resulted in a strong dichotomy in relation to the primary or secondary character of the problematic exercise that might be limiting the capacity of the instruments to adequately capture the multidimensionality of this construct. Conclusions: Given the interest in understanding the complexity surrounding the problematic exercise, future research should develop more comprehensive definitions of this construct. This would allow a greater conceptual consensus to be reached that would allow progress to be made in the study of the problematic exercise.
A pszichológia és a pedagógia az oktatáspolitikában
Authors: Sáska Géza 
Published: April 2021

Összefoglaló. A pedagógia és a pszichológia tudománya között
szorosabb és szervesebb a kapcsolat, több a párhuzamosság, mint a pedagógia és
más társadalomtudományok között. Az Educatio jelen füzetének
bevezető tanulmánya vázlatosan érinti Herbarttól az 1980-as évekig a változó
értelmezésű pedagógia és az (alkalmazott) lélektan tudományának eszmei
kapcsolatát, intézményesülésüket a centralizált állam és a növekvő politikai
hatalom világában. A tanulmány ismerteti a lapszámban megjelent sztálini és a
posztsztálini időszakban a pszichológia és pedagógia viszonyrendszerének
változásait, a pszichológia intézményesülését bemutató tanulmányokat.
Summary. There is more parallelism, a closer and a more organic
relationship between pedagogy and the science of psychology than between
pedagogy and any other social science. The introductory study of
Educatio 2020, No. 4. provides a sketchy historical survey
of the relationship between the science of changing pedagogy and (applied)
psychology in the world of centralized state and growing political power and
ideology, from Herbart to the 1980s. This introduction briefly describes the
studies in the issue that discuss changes in the relationship between psychology
and pedagogy in the Stalin and the post-Stalin period.
A magyar, német és belga felsőoktatási intézmények eredményessége
Authors: Kosztyán Zsolt Tibor , Csányi Vivien Valéria , Banász Zsuzsanna , Telcs András 
Published: April 2021

Összefoglaló. A tanulmány a magyarországi felsőoktatási
intézményeket vizsgálja, kontrollként kiegészítve németországi és belgiumi
intézményekkel. E három ország (főként hazánk) intézményei közül számos nem
szerepel a nemzetközi rangsorokban, ezért további elérhető szekunder forrásokból
számítottunk tipikus rangsorképző indikátorokat a rangsorokban általában
vizsgált tényezőkre, mint az oktatás, a kutatás, a nemzetköziesség, valamint a
finanszírozás. Ez alapján elsősorban arra a kutatási kérdésre kerestük a
választ, hogy a magyar felsőoktatási intézmények miként (mely indikátoraik
javításával) kapaszkodhatnának fel a rangsorok szerint világszinten legjobbnak
tartott 100, illetve 200 intézmény közé. Elemzéseink alapján a magyar
felsőoktatási intézményeknek a következő indikátorokban szükséges leginkább
fejlődniük: egy oktatóra vetítve három mutatóban (PhD-fokozatot szerzők száma,
nemzetközi publikációk száma, kutatási bevétel), az alapszakos hallgatókra jutó
oktatók számában, valamint a külföldi oktatók arányában.
Summary. This study examines higher education institutions in
Hungary, using German and Belgian institutions as a control group. Since many of
these institutions are not represented in international rankings (mainly
Hungarian institutions), we use further available ranking indicators from
different secondary sources – these indicators are related to education,
research, internationalization, and funding. We aim to answer the following
research question: how Hungarian higher education institutions can reach and be
among the top 100 and top 200 best institutions in the world? Based on our
analyses, Hungarian higher education institutions need to develop the most in
the following indicators: per lecturer in three indicators (number of Ph.D.
graduates, number of international publications, research revenue), number of
lecturers per undergraduate student, the proportion of foreign lecturers.
Első generációs oktatók pályaképe és önreflexiói
Authors: Bocsi Veronika 
Published: April 2021

Összefoglaló. Vizsgálatunk során 11 első generációs oktató életútját
és pályaképét tekintjük át, elemezzük az őket ért hátrányokat, a helyzetükből
fakadó előnyöket, valamint igyekszünk feltárni az oktatási karrierjük főbb
állomásait, továbbtanulásuk motivációit és pályaválasztásuk történetét. Az
eredmények szerint az interjúalanyok tapasztalatai diverz mintákat mutatnak,
tehát a hátrányok megélése nem általános jelenség, bár a megkérdezettek nagyobb
részénél az erre utaló elemek megragadhatók. A hátrányok azokon a
tudományterületeken jelentkeznek élesebben, ahol a kulturális tőke felhalmozása
a szakmai identitás markánsabb részét képezi, vagy pedig az adott intézmény
társadalmi háttere (mind oktatói, mind hallgatói) kedvező.
Summary. The aim of this study is to recover the career and life
path of 11 first-generation academics. We try to map their disadvantages or
advantages – which are embedded in their social circumstances – motives of their
further studies and the history of their career choices. The results have shown
that their experiences are diverse. The experiencing of handicaps does not work
in every case nevertheless these kinds of traces can be found in some forms by
most of them. These handicaps seem to be more significant in the field of those
disciplines in which cultural capital is rather the parts of the professional
identities and professional socialisation or the prestige of the institution is
high.
Politik Hukum Indonesia yang Berkaitan dengan Statuta Roma dalam Penegakkan Pelanggaran Hak Minoritas
Authors: Novianti Linda 
Published: April 2021

Berbagai generasi sudah pasti mewarisi sejarah dan tidak akan pernah bisa melupakan petaka berdarah kerusuhan Mei 1998. Meskipun generasi milenial seperti era masa kini tidak turut berperan pada masa itu, namun dengan membaca sejarahnya, tentu dapat mengundang perasaan mengerikan tatkala membayangkannya. Terkait Etnis Cina misalnya, yang dikejar-kejar, dipukuli, dianiaya, dibunuh secara keji, bahkan diperkosa ramai-ramai. Barang dagangan dalam ruko-ruko milik mereka dijarah, lalu dibakar. Sepertinya tidak terhitung banyaknya rumah, ruko, mall, gedung perkantoran, bahkan sarana olahraga yang dibakar massa saat kerusuaan tersebut terjadi. Adapun mengenai metode yang digunakan dalam penelitian ini adalah metode dekriptif, dengan hasil analisis bahwa perlindungan atas hak minoritas beberapa upayanya, dapat dilakukan dengan pemenuhan kewajiban serta ikrar dari berbagai negara seperti halnya yang tercantum dalam perjanjian internasional, memberikan pertimbangan terhadap berbagai kepentingan kaum minoritas dalam rangka pengembangan kebijaksanaaan, serta menyokong pemahaman kebudayaan, tradisi dan bahasa kaum minoritas yang berada pada wilayah tertentu dengan mengulurkan jaminan anggota kelompok minoritas juga memiliki kesempatan yang sama secara menyeluruh. Sementara itu, mengenai prinsip dasar hukum hak minoritas merupakan panduan bagaimana negara mengatur dan memenuhi hak-hak kelompok minoritas. Aturan-aturan tersebut meliputi produk hukum nasional, upaya ratifikasi terhadap konvensi dan kovenan internasional yang berhubungan dengan hak-hak kelompok minoritas di Indonesia. Kemudian mengenai politik hukum Indonesia yang berkaitan dengan Statuta Roma dalam menangani pelanggaran hak minoritas, diantaranya lahir Undang-Undang Nomor 26 Tahun 2000, sebagai jembatan politik hukum Indonesia, dimana keberadaan peraturan perundang-undangan tersebut dianggap sebagai upaya nyata Indonesia untuk menghindarkan diri dari campur tangan internasional dalam urusan domestik terkait dengan kejahatan kemanusiaan.
Judicial Review oleh Mahkamah Konstitusi sebagai Fungsi Ajudikasi Konstitusional di Indonesia
Authors: Andiraharja Diyar Ginanjar 
Published: April 2021

Penelitian ini ditujukan untuk menganalisa kewenangan Judicial Review oleh Mahkamah Konstitusi sebagai ajudikasi konstitusional menurut prinsip konstitusionalisme dan demokrasi. Muncul penilaian terhadap Mahkamah Konstitusi selain menjadi negative legislator juga berkembang menjadi positive legislator yang merupakan kewenangan lembaga pembentuk undang-undang. Metode yang digunakan berupa penelitian hukum normatif. Kepustakan yang dikaji digunakan untuk menjwab pertanyaan penelitian. Dari penelitian ini diungkapkan Mahkamah Konsitusi dalam menjalankan kewenangannya melakukan Judicial Review, pada praktiknya terjadi suatu perdebatan di mana dalam model putusan Mahkamah Konstitusi dianggap bertentangan dengan prinsip konstitusionalitas dan prinsip demokrasi dalam hal pembentukan suatu kebijakan. Beberapa model tersebut dianggap melampaui kewenangan Mahkamah Konstitusi berupa adanya putusan yang berisi argumen kebijakan serta adanya putusan yang di dalamnya ada perumusan norma baru. Kesimpulan dari penelitian ini aktivitas menafsirkan UUD 1945 memungkinkan lahirnya sudut pandang judicial activism yang dapat memposisikan Mahkamah Konstitusi sebagai badan peradilan yang memiliki supremasi dalam ajudikasi konstitusional, walaupun pembentukan Mahkamah Konstitusi itu sendiri sebenarnya sebagai bagian dari upaya pembaharuan konstitusi dalam memperkuat prinsip pemisahan kekuasaan dan prinsip check and balances. Sehingga perlu dikedepankan proporsionalitas peran Mahkamah Konstitusi dalam ajudikasi konstitusional.
What Matters to Malaysian Students Retention: University Image or External Environment?
Authors: Et. al. Amran Harun , 
Published: April 2021

In Malaysia, the growth of higher education institutions provides not only more opportunities but increasing competition within the industry. Despite its enormous potential, investigating student retention and its antecedents will provide vital input for the industry to sustain and strategize the most appropriate marketing actions. Therefore, this study aims to investigate how university image (program, facilities, reputation, and cost) and external environment (influences of peers and family and students’ achievement) have a relationship with students’ retention. A total of 300 university students participated in this study, which they were required to complete the online questionnaire. This study employed a correlational study using a cross-sectional design and close-ended questions. Remarkably, the finding of the current study confirmed only one dimension of the university image, namely reputation, had a positive relationship with students’ retention. In contrast, university image attributes such as program, facilities, cost; and external environment, which is peer/family influence and achievement, have no relationship with students’ retention. Future recommendations are also discussed in dealing with the students' retention issues concerning students’ characteristics such as socioeconomic status and the mediating variable effects.

Published: April 2021

Vision is one of the key senses allowing citizens to communicate with the natural world. There are about two hundred million blind people globally and visually disabled people obstruct numerous everyday practices. It is also really critical that blind people recognize their world and realize with which items they communicate. This paper review all the method and tool related to camera-based device to enable the blind person interpret text patterns written on items kept in hand. This is the system for helping individuals with visual disability interpret and translate text patterns to the audio output. The framework first suggests the approach to take an image from the camera and the area of the target to retrieve the object from the context and derive a text pattern from that object. Diffrent algorithm is assessed in various scenes. The observed text is linked to the blueprint and translated into the performance of the voice. Localized and binarized text patterns utilising Optical Character Recognition (OCR). The text is translated to an audio output. The voice quality is given to theblind person.
