Authors: PYVOVARSKA K. , STEFANIUK O. 
Published: December 2023

This article examines the activities of the Poltava Adult Education Center in 2021 as an environment for personal and professional development. The adult education center of Poltava was created in 2018 on the basis of the public organization "Adult Education Center of Poltava Region". This period was chosen as the last year before the full-scale invasion, which made adjustments to the work of the Center. Quantitative and qualitative indicators, features of work, target groups, areas of activity were considered. Based on the results of the analysis of these data, conditions were formed under which the Center can really contribute not only to the professional, but also to the personal development of its students:
1) Specification and segmentation of the target audience and beneficiaries according to the model of education centers
2) Active feedback with listeners throughout the time of operation of the data center
3) Diversification of courses aimed at different areas and competences of students
4) Inclusion of not only professional courses, but also aimed at self-development, psychological stability, and stress management
5) A mixed online and offline format that allows for a flexible approach to the needs of listeners
6) Engagement of professional trainers who can not only teach certain courses, but also have soft skills to support listeners who are often in a difficult life situation
7) Creation of a proactive environment in which listeners can communicate and interact, involvement of various channels of informing beneficiaries
8) Continuous search for partners, including for additional funding, to maintain free courses for students
9) Efforts to maintain a gender balance for the maximum possible functioning of the data center.
In this way, adult education centers can become centers of city and community development, and the experience of the adult education center in Poltava in 2021 can indicate how it is possible to build the work of similar institutions.
WAR-FOCUSED SOCIAL DOCUMENTARY AS A TOOL FOR GLOBAL CHANGE
Authors: RUDYCH O. , CANALS-BOTINES M. , KOHUT I. 
Published: December 2023

The article observes the war-focused social documentary use while calling for global change. It considers a form of documentary photography within the idea to draw the wide public's attention to vital ongoing war-caused social problems and issues.
We also characterize social documentary as a critical genre of photography, dedicated to reflection of the life of different people, underprivileged or disadvantaged as a result of the war. The terms “war”, and “war of aggression” are concretized. It is also stated, that while conversations, political speeches, press reports or publications, the word “war” may be used to express any serious struggle, strife or campaign. Thus, references are frequently made to “war on corruption”, “war against drug dillers”, “war of worlds” or “war of genders”: the metaphor of war usually serves to convey the stressfullness of the situation, and such a metaphor must not be taken literally.
Also, the difference between Social Documentary and Photojournalism is characterized: photos are usually taken for the future reference, whereas photojournalism images are predominantly meant for the short-term public involvement. Social Documentary images definitely may be stored for the long-term study, enabling better understanding of the modern world we live in, making sense of our living, discovering the way other people live.
Article characterizes the main thematic motives of social documentary, such as: child labor, child neglect, homelessness, poverty, impoverished children and the elderly, and hazardous working conditions, and outlines the peculiarities of their interpretation in the context of war.
Social documentary is to preserve the most important events or parts of the history – some details or archival footage that would rather be buried. This gives not only a better understanding of current events, but also a prospective of what we might face in the future.
Social documentary can be an effective tool to influence our preconceptions, and develop empathy towards human beings or any creature suffering. By bringing personal stories to light, documentaries can aim much-needed wider audience’s awareness on to war-caused social problems, and facilitate the search for solution.
The article also deals with the difference between Social Documentary and Pictorial Manipulation, which are often used to shape public opinion within global digitalized informational space.
Une grande école dans les commémorations de la Grande Guerre
Authors: Azzola Oivier 
Published: December 2023

L’École polytechnique a formé trois des quatre généraux qui ont été à la tête de l’armée française au cours la Grande Guerre, et environ un quart de tous les généraux français du conflit. Environ 900 polytechniciens sont morts pour la France. Un siècle après ce conflit, l’identité de cette école est en pleine transformation par l’ouverture de nouveaux
cycles de formations. Dans ce contexte, comment les différents acteurs en oeuvre à l’École polytechnique (élèves, associations d’anciens, direction) ont-ils abordé les commémorations du Centenaire ? Le service d’archives a-t-il été sollicité et comment a-t-il été impacté ? Au travers de l’exemple des commémorations, nous nous interrogerons donc sur le positionnement des archives dans les questions de mémoire, d’histoire et d’identité.

Published: December 2023

Lampu light emitting diode (LED) populer digunakan dalam berbagai macam aplikasi, karena penggunaan daya yang rendah, efisiensi yang tinggi dan perawatan yang rendah. Keuntungan LED lainnya adalah awet dan ramah lingkungan karena lebih sedikit mengandung komposisi zat beracun jika dibandingkan dengan jenis lampu lain. Untuk mencapai efisiensi yang tinggi dalam transfer energi pada catu daya LED, diterapkan topologi switched mode power supply (SMPS). SMPS diimplementasikan dengan pulse width modulation (PWM) yang beroperasi pada frekuensi konstan, menghasilkan emisi yang signifikan disejumlah frekuensi melalui mekanisme conducted dan radiated, emisi ini dinamakan electromagnetic interference (EMI). Sebagai akibatnya, banyak lampu LED berpotensi tidak bisa memenuhi standar electromagnetic compatibility (EMC). Pada penelitian ini dilakukan perancangan dan implementasi filter EMI pasif untuk meredam conducted emission pada lampu LED yang ada dipasaran. Filter EMI pasif berupa low pass filter (LPF). Sebelum lampu LED diterapkan filter pasif EMI, conducted emission yang terukur melebihi standar regulasi CISPR 22 class B, nilai emisi tertinggi mencapai 82,5 dBÂµV pada frekuensi 299,25 kHz atau melebihi standar CISPR sebesar 30,9 dBÂµV. Saat filter pasif EMI dipasang lampu LED terjadi reduksi conducted emission pada rentang frekuensi 150kHz â€“ 1,65MHz dengan nilai rataâ€“rata sebesar 23,3 dBÂµV dan nilai reduksi maksimal sebesar 34,7 dBÂµV.

Published: December 2023

Data from WHO 2015 shows that 70% of deaths in the world are caused by non-infection diseases, 45% are caused by heart and blood vessel disease, namely 17.7 million from 39.5 million deaths. Riset Kesehatan Dasar (Riskesdas) reported that in 2018, there were 15 of 1000 people, or 2,784,064 individuals in Indonesia suffering from heart disease. Symptoms of heart abnormalities often come suddenly. Therefore, early recognition can help to avoid heart attacks. Doctors currently use a heart sound / phonocardiogram (PCG) to assess the performance of the heart using a stethoscope. The PCGâ€™s diagnosis is very influenced by the subjectivity of doctors because of its relatively weak and physical limitations. So that the possibility of a False Positive Result happening is quite high. To minimize this risk, a Computer Aided Diagnosis (CAD) PCG signal was developed. Several studies have proposed a PCG diagnostic method using the wavelet or Welch method and based on Neural Network are more complex. In this study, a simple diagnosis method is proposed so that the computation is easier and faster with good accuracy. The PCG signal is amplified twice, then the Fast Fourier Transform (FFT) process is carried out to obtain the characteristics of the fundamental frequency and max amplitude. The classification stage uses the Multi Layer Perceptron (MLP). From testing of 55 data PCG, the results obtained accuracy of 90%, sensitivity of 80%, PPV of 100% and NPV of 83.33%.

Abstract
In this study, amorphous boron carbide (B

C) and hydrogenated amorphous B
x
C (B
x
C:H) films were deposited via magnetron sputtering to investigate the effects of hydrogen on the film properties. The critical load decreased with increasing H2 flow ratio, probably due to an increase in the internal stress. In addition, the optical bandgap increased with the H2 flow ratio increased. The bandgap was controlled by the chemical bonding of carbon atoms and the chemical composition of films. The resistivity of the films increased with the H2 flow ratio and bandgap energy. The current–voltage characteristics of B
x
C(:H)/n-type Si heterojunctions under white light illumination showed that the short-circuit current density and open-circuit voltage were higher than the previously reported values. Results revealed that the introduction of hydrogen during deposition reduced the short-circuit current density, fill factor, and conversion efficiency, whereas the open-circuit voltage remained almost unchanged.
