Published: May 2023

In this study, we report biodiesel production from waste cooking oil using CaO catalyst derived from Madura limestone through a transesterification reaction. Many limestone quarries in Madura can be used as heterogeneous catalysts because they are cheap, easy to separate, and have high basicity. Conversion of limestone into CaO catalyst through calcination at 900°C for 3 hours. The CaO catalyst formed was characterized using X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) instruments. Biodiesel formed through the transesterification reaction was analyzed using GC-MS. Furthermore, biodiesel blends from waste cooking oil and pure diesel were prepared in volume percentages (B-10, B-20, B-30, B-40, and B-100) for testing on diesel engine performance. The results of testing the highest torque and brake horsepower (BHP) were obtained on pure diesel fuel (S-100) at 2.49 Nm and 381.12 watts, respectively. The lowest fuel consumption at 1500 rpm is produced on the B-20 at 0.186 kg/h. Overall, the emission characteristics of carbon monoxide (CO), nitrogen oxides (NOx), and nitrogen monoxide (NO) with the lowest concentration resulted from biodiesel blends rather than pure diesel.

Authors: Ariyanto Sudirman Rizki , Suprayitno Suprayitno , Wulandari Retno
Published: May 2023

In this paper, Metallic Catalytic Converter (MCC) is installed in motorcycle exhausts to produce the minimum CO as well as to produce the optimum engine power. The results from previous research were collected and then used to predict the best MCC design using the Artificial Neural Network Multi-Objective Genetic Algorithm (ANN-MOGA). In addition, the ANN parameter tuning process was also carried out using the Taguchi method to find the initial weighting and bias that is able to provide the best and the most stable performance to predict the best MCC design. The best two sets of design solutions out of 70 sets of Pareto solutions were obtained by ANN-MOGA. Those two MCC designs are the optimum emission design and the optimum multi-objective design. The verification results show that the optimum multi-objective design tends to be superior in terms of CO emissions and engine power. In terms of CO emissions, the optimum multi-objective design gets a larger S/N ratio of -10.98, while the optimum emission design only gets an S/N ratio of -11.21. Meanwhile, in terms of engine power, the optimum multi-objective design gets a larger S/N ratio of 16.13, while the optimum emission design only gets an S/N ratio of 15.86 S/N. It is in line with the ANOVA test results which show that the optimum multi-objective design is proven to be better than the optimum emission design.

Published: May 2023

As of today, only a few people know about carbon black. Their knowledge and understanding are also limited to the fact that carbon is charcoal from coconut shells or black activated carbon. In addition, some people only know carbon as carbon copy and ink material. On the other hand, there is another type of carbon that comes from oil content and can be used for various industrial purposes. This carbon is produced and used with advanced and modern technology, which is called carbon black. Currently, by looking at the market signal, carbon black has become a very profitable commodity. Carbon black industries develop systems and technologies to produce the best quality with minimized environmental effects. In fact, because of the promising price and high market demand, carbon black factories invest in advanced production equipment. In its development, through continuous research and by utilizing advances in industrial technology, currently, carbon black can be added to various materials to improve the physical, electrical, or optical properties of the material.

Published: May 2023

The impact of media on human behavior and attitudes is a widely debated topic in the current digital era. This research paper aims to analyze the role of television as a source of entertainment and social connection. Based on previous studies, it is evident that television has the potential to create a sense of companionship among individuals facing isolation. Moreover, it is argued that individuals tend to share their emotional experiences less when they do not interact with others face to face. Additionally, the paper explores the evolution of drama as a form of mass entertainment, which has gained immense popularity in the 20th century. The research argues that modern drama reflects the complex struggle of life and human nature, making it a universal medium of expression. The paper concludes that the media has a significant impact on society and its values, shaping the way people perceive the world around them.

The "New Left" in Chile in the face of existential challenges
Authors: Diakova Ludmila
Published: May 2023

The article examines the ideological principles of the Chilean "New Left" and the political practice of the government of G. Borich during his first year in power, the process of developing key reforms, fulfilling pre-election promises to form a socially-oriented development model, completing work on the draft of a new constitution. Interaction with the centrist and left-wing radical line in the national political space played an important role. The difficult path of finding answers to the existential challenges of real politics has led to a significant transformation of the president's tactics, a revision of a number of priorities, a gravitation to the positions of centrism and the format of the "compromise model". The changes resulted in increased disagreements within the ruling coalition, a large radicalization of supporters of an irreconcilable ideological position, which can significantly complicate the further work of the government.

Published: May 2023

In continuation of our reserach for synthesizing heterocyclic derivatives with a broad range of biological activities, the current research was performed to synthesize 3β-hydroxypregn-5-ene-20-one derivatives of coumarin, isoxazole, pyrazole, pyridine and pyrimidine and screen for antitumor activity. Synthesis of amino-thiopephen derivatives (1a-1b) was performed through reaction of 3β-hydroxypregn-5-ene-20-one with ethyl cyanoacetate or malononitrile and sulphur. 3β-Hydroxypregn-5-ene-20-one was reacted with ethyl cyanoacetate in the presence of hydrazine, urea or thiourea to obtain aminopyrazole (3), aminopyrimidine (4a-4b) derivatives, respectively. The amino-thiophene derivatives (1a-1b) further reacted with either phenylisothiocyanate or benzoylisothiocyanate to form fused thienopyrimidine derivatives (5a-5d). The products 1a and 1b were also treated with ethyl cyanoacetate to afford cyanoacetamidothiophene derivatives (6a-6b) which were converted to fused thienopyridone derivatives (7a-7b) through cyclization reaction. The compounds 6a and 6b were allowed to react with different carbonyl compounds including salicyaldehyde, cyclopentanone-sulphur mixture, acetylacetone and malonaldehyde to prepare coumarin (8a-8b), cyclopentylthiophene (9a-9b) and 2-pyridinone (10a-10d) derivatives respectively. Furthermore, the reactions of hydroxylamine hydrochloride and benzoylacetonitrile with the compounds 6a-6b separately afforded new aminoisoxazole (12a-12b) and phenylpyridone (14a-14b) derivatives, respectively. The structures of new products were established through IR, 1H NMR, 13C NMR spectroscopic and mass spectrometric analysis. The synthesized compounds (1a-1b to 14a-14b) displayed in-vitro antitumor activity against human cell-lines, including MCF-7 (breast adenocarcinoma), SF-268 (CNS cancer) and NCI-H460 (non-small lung cancer cell). The results suggested that all the screened products exhibited cell growth inhibitory activity in a dose-dependents manner. However, the compound 12a showed highest level of inhibition against all three cell-lines.

Apigenin, non-toxic and non-mutagenic flavonoid, is an alternative to classical drugs that interact with membranes. Hence, the objects of the study were to examine its effects on liposomes made of egg yolk phosphatidylcholine (EYPC) with the use of 1H NMR, four-electrode BLM and EPR techniques, and determine its activity on lipids and proteins of human cervix carcinoma (HeLa) cells. In addition its protective efficacy against H2O2- induced oxidative shock was investigated. FTIR spectroscopy was applied to study molecular interactions with membrane lipids and proteins of HeLa cells. Microscopic techniques (SEM, light, and fluorescence), flow cytometer analysis, and NR assays were employed to reveal apigenin involvement in apoptosis in different cell conditions. Apigenin affected mainly the region of choline head groups and the hydrophobic core below this area. Simultaneously, the ordering effect was shown. The fingerprint region of lipids in the HeLa cells was found as a target for apigenin. Furthermore, in the amide I and amide II regions, a decrease in β-sheets and an increase in turns, loops, and unordered structures were noted. Apigenin reduced viability of cells and induced apoptosis. SEM observations revealed characteristic changes in morphology of the examined cells. Pretreatment of HeLa cells with apigenin protected them against H2O2-induced oxidative stress by the increase in glutathione content as well as superoxide dismutase and catalase levels. The consequences of molecular changes related to membranes and cancer cells make apigenin a unique and very interesting bio-compound with great significance for medical and biological applications.
Localization patterns of gold mineralization in the Phuoc Son area, Central Vietnam
Authors: Tran Van T. , Ignatov P. A. , Mai Trong T.
Published: May 2023

Background. In this paper, the authors aim to reveal the localization patterns of gold mineralization in the Phuok Son region of Central Vietnam, which formed a Proterozoic-Cambrian metamorphic complex in the zone of the Late Paleozoic Benzhang–Queshon granite block.

Aim. To determine the localization patterns of gold mineralization in the Phuoc Son area, Central Vietnam.

Materials and methods. The research was based on geological materials, as well as mine working and appraisal well data. The material composition of the materials was studied using 15 transparent sections and 18 polished sections. In total, 127 samples were subjected to atomic absorption spectroscopy.

Results. Within the Phuoс Son gold ore field in Central Vietnam, the site of the Baidat and Baigo mines located in the zone of reverse-shear termination was investigated. Here, the gold ore bodies are represented by quartz-sulfide veins subparallel to schistosity. The ore-bearing zones are layered zones of tectonic faults, which formed at the end of the reverse-shear period and complicated the western limbs and locks of the anticlines. These zones were formed under regional sublatitudinal horizontal stresses. The horizons of carbonaceous quartz-sericite schists are of great importance in ore control. There are steeply dipping post-ore faults that displace ore bodies. Two gold mineralization stages can be distinguished. The early stage was characterized by a wide development of sphalerite and a smaller amount of gold. The later stage was associated with the main precipitation of gold and formation of galena. According to the geochronological data on the argon isotopy in biotite, the gold mineralization at Baidat and Baigo was probably formed in the Triassic (250–200 Ma ago), at the stage of extinction of the regional metamorphism of the Indosinian orogeny

Conclusion. The results obtained should be used when conducting local forecasting of gold deposits in Central Vietnam.

Authors: Budykina T. A. , Gandurina L. V.
Published: May 2023

Background. The importance of studying the properties of argillaceous rock materials is determined by their widespread application in various industries. At the same time, identification of argillaceous minerals is associated with a number of difficulties.

Aim. To study the properties of argillaceous rock materials collected in different sites by the method of simultaneous thermal analysis to reveal their characteristic patterns and to identify their composition.

Materials and methods. Natural materials from different geographical sites in Russia and neighboring countries were studied by the method of simultaneous thermal analysis.

Results. The use of simultaneous thermal analysis for studying the properties of argillaceous materials allows their behavior to be studied under temperature exposure. The composition of rock samples can be identified by comparing their thermogravimetric curves with those of known rocks.

Conclusion. The possibility of using thermal analysis for identifying the presumed mineral composition of the studied rock material was established. However, the diversity of soils on the planet impedes drawing a definite conclusion about their mineral composition. Therefore, thermal analysis should be applied in combination with other research methods, such as XRD, sediment, optical, etc., analytical techniques.

При побудові комп’ютерної моделі іонного треку в біосенсорі важливо враховувати основні структурні особливості реального треку. Як тепер установлено, перехід від треку до об’єму зразка не є різким. У цій роботі враховано тришарову структуру внутрішніх стінок треку (включаючи Penumbra). Показано, що проходження зарядженої рідини через трек істотно залежить від дефектної структури цього перехідного шару. Оскільки профіль густини струму, що протікає через рідинний трек, залежить від дефектної структури перехідного шару у треку, важливо визначити умови іонного бомбардування, які забезпечують його оптимізацію. Таким чином, на першому етапі створення трекової структури необхідно вирішити певні задачі радіаційної фізики взаємодії швидких іонів з тонкою плівкою. У свою чергу, ці характеристики структури треку визначатимуть чутливість біосенсора до виявлення забруднень у конкретному середовищі. Показано, що важливо враховувати специфіку впливу кожного з тришарових пограничних шарів на протіканні «носій» рідина. Рідина-носій означає «чисту» речовину, в якій слід визначати забруднення. Дослідження показали, що оптимізація функціонування трекового біосенсора є багатопараметричною задачею, в якій необхідно змінювати декілька параметрів одночасно. Таким чином, комп’ютерне моделювання дає можливість бути ефективним методом оптимізації параметрів трекового біосенсора. Подальші дослідження мають бути спрямовані на виявлення кореляції між структурними особливостями Penumbra та параметрами біосенсора. Однак це потребує значного вдосконалення алгоритмів і комп’ютерної моделі.

Кукурудза – це третя за значенням після пшениці та рису, важлива зернова культура в Україні та в усьому світі. Її цінність і універсальність полягають у напрямах, де її використовують: як кормову та технічну культуру, а також у харчовій промисловості. Тому збільшення посівних площ кукурудзи, одержання стабільно високих урожаїв є дуже важливим питанням, адже наша країна входить до п’ятірки найбільших експортерів зерна кукурудзи у світі. Меліоративні заходи дали змогу залучити в сільськогосподарське використання та перетворити на орні землі значні площі перезволожених земель, які раніше не використовувались. Важливою проблемою осушуваних систем Передкарпаття є забезпечення сприятливого меліоративного стану земель, зокрема й на основі поліпшення їхніх агрофізичних властивостей. Тому питання вибору технологій, які варто застосовувати на осушуваних землях для забезпечення приросту обсягів виробництва основних сільськогосподарських культур без порушення сучасних стандартів збереження навколишнього середовища, є актуальним. Мета дослідження – дати порівняльну оцінку впливу різних способів основного обробітку на агрофізичні показники дерново-підзолистого ґрунту та продуктивність посівів кукурудзи на зерно в умовах Передкарпаття. Установлено, що вологість ґрунту на час посіву кукурудзи була вищою на варіантах, де проводилася оранка із ґрунтопоглибленням. У фазі воскової стиглості вища вологість у підорному шарі ґрунту відмічена на варіантах, де проводилося його розпушування. Нижчу об’ємну масу, вищу загальна шпаруватість і повітроємність отримано на варіантах із розпушуванням підорного шару ґрунту. Істотний приріст урожайності зерна кукурудзи отримано на варіантах, де проводилася оранка на 20–22 см, оранка на 20–22 см + розпушування на 12–14 см, глибока оранка без обертання скиби (25–27 см), причому найвищу врожайність зерна забезпечила оранка на 20–22 см + розпушування на 12–14 см. Вищий рівень рентабельності (60,2%), енергетичний еквівалент (2,32) забезпечила оранка на 20–22 см + розпушування на 12–14 см нижче рівня оранки.
Dalla concessione al diritto soggettivo. Cittadinanza e assistenza nel dibattito sull'attuazione costituzionale
Authors: Canepa Giacomo
Published: May 2023

La questione del diritto all'assistenza nella legislazione italiana è spesso ridotta all'analisi dell'articolo 38 della Carta costituzionale. In realtà, la legittimazione del diritto soggettivo del cittadino all'assistenza fu l'esito di un lungo processo: la continuità dei principi della carità legale crispina, il carattere programmatico dei diritti sociali e la situazione di stratificazione normative ne comportarono per un trentennio la sostanziale negazione nella prassi amministrativa. L'articolo si propone di svolgere una ricognizione sul dibattito politico, amministrativo e giuridico che seguì l'approvazione dell'articolo 38, concentrandosi sui fattori ideali e ideativi che ispirarono le politiche pubbliche. L'autore ripercorre le tappe dell'allargamento della cittadinanza sociale, soffermandosi in particolare sull'assistenza post-bellica nel dopoguerra, sulla protezione sociale dei ciechi civili varata nel 1954, sulla stagione della programmazione economica e sulla regionalizzazione.
Diritto alla salute e rischio nucleare. I tecnici della Sanità nel dibattito sull'atomo civile degli anni Settanta
Authors: Papa Catia
Published: May 2023

L'articolo esamina le posizioni dei tecnici dell'Istituto superiore di sanità in tema di sicurezza nucleare nel corso degli anni Settanta. Le loro valutazioni sul rischio nucleare contribuirono ad alimentare il dibattito sull'atomo civile all'interno del Pci in occasione del Piano energetico nazionale (1975) e al cospetto del nascente movimento antinucleare. L'istituto entrò infine in conflitto con il ministero dell'Industria, evidenziando le linee di frattura tra istituzioni, e tra istituzioni e territori, sul destino nucleare dell'Italia.
Imprese e imprenditori italiani in Argentina nella storiografia italiana e argentina, dalla fine dell'Ottocento a oggi
Authors: Bertagna Federica
Published: May 2023

L'articolo analizza la storiografia italiana e argentina su imprese e imprenditori italiani emigrati in Argentina, in una prospettiva di lungo periodo. Ne confronta le caratteristiche nelle tre fasi di sviluppo identificate (da fine Ottocento agli anni Sessanta del Novecento; dagli anni Sessanta agli anni Ottanta; dagli anni Ottanta a oggi). Conclude che nella storiografia italiana predomina una visione "etnica", che esalta il contributo fornito da imprenditori e imprese italiane al progresso argentino. La storiografia argentina si caratterizza invece per la scarsa attenzione prestata alla matrice italiana, nel quadro di una visione che dagli anni Settanta diventa critica nei confronti dell'operato degli imprenditori. In entrambi i paesi gli autori fino agli anni Cinquanta non sono in prevalenza storici di mestiere ma pubblicisti.

Authors: Ridolfi Alessandro , Materassi Paolo , Cecchi Arianna
Published: May 2023

Il lavoro clinico con adolescenti figli di genitori separati costituisce il nucleo di queste ri-flessioni, dedicate alla delusione affettiva vissuta a seguito di tale evento familiare. Questa attività, riferita ad un ambulatorio territoriale (in due comuni dell'area fiorentina Nord-Ovest) del Servizio di Salute Mentale Infanzia e Adolescenza dell'Azienda USL Toscana centro, si inserisce nel contesto del mandato istituzionale di tutela del minore e di sostegno alla famiglia che il Servizio sanitario riceve dai tribunali nei casi di separazione conflittuale. A partire dai risultati delle ricerche recenti sull'argomento vengono presentate alcune considerazioni teoriche di carattere evolutivo-intersoggettivo e esperienziale-affettivo. Infine sono proposte alcune considerazioni riguardo all'intervento clinico.
Racialized xenophobia and the uneven distribution of welcome to foreigners in Brazil
Authors: Deivison Faustino , Leila Maria de Oliveira Oliveira , Valter Roberto Silvério
Published: May 2023

How does xenophobia manifest itself in societies whose capitalism was structured through colonialism? To what extent can studies on contemporary manifestations of racism help to understand xenophobia in these societies? In this work, we rely on the Fanonian concept of racialization to investigate the genesis and function of migratory policies in republican Brazil. To this end, we return to important histori-cal landmarks that allow the relationship between capitalism, racism and immigra-tion in Brazil to be highlighted. As a result, we suggest that the migratory policies in the country corresponded to national, racial and class interests that imposed a par-ticular dynamic on them, not properly contemplated by some explanatory models, thought from Europe. To account for this particularity, we suggest the concept of racialized xenophobia.
The impact of demographic factors on national security

Published: May 2023

The article discusses the demographic factors that have the greatest impact on national security. The shift in the values of modern society has changed the emphasis in the main factors characterizing national security. The population ageing, increased health care costs and pension payments, as well as the growing economic burden on people of working age, give reasons to consider the demographic component as the main one in the system of national security. The purpose of the study is to quantify the impact of individual demographic factors on national security indexes. The authors compared the main demographic indicators of the Russian Federation and developed countries. Based on the data for developed countries the threshold values of the main demographic indicators were determined. Regression analysis to determine the dynamics of demographic indicators for the Russian Federation was applied, and a generalized index of the demographic component of national security was determined. In addition, elasticity coefficients were calculated to determine the impact of individual demographic indicators. The authors found that previously overlooked parameters of demographic security indicators, such as the share of the older citizens in the total population and the demographic burden of the elder population, are important in the national security assessment. The recommendations on improving the demographic component of Russia's national security were proposed. For the Russian Federation, all indicators are in the critical range (below the minimum threshold value).
The role of narratives in the preservation of post-war built legacies in Budapest
Authors: Bittenbinder Franz
Published: May 2023

Hungarian professionals have highlighted the vulnerability of post-war built legacies in Budapest. Their reference point is the recent transformation of central areas showing a significant number of demolitions and a small number of conservative refurbishments. This is commonly attributed to the narratives of revisionist memory politics and/or the stigma of architecture built under state socialism. In contrast, professional activism and recent official listings have indicated a change of paradigms towards the extension of the official patrimonial acknowledgement to post-war built legacies. Throughout the case of the House of Diplomats, this article presents the origins of diverging narratives and discusses their impact as risk or potential in architectural preservation.
Architettura e regime: eredità del Moderno
Authors: Galliani Pierfranco
Published: May 2023

Una peculiarità evidente del xx secolo è la relazione tra architettura e politica, in particolare quella dettata dai totalitarismi che hanno pervaso numerose strutture sociali e statuali. Questo rapporto si è snodato tra analogie e differenze, proponendo in origine una continuità tra passato e futuro, tramite contributi sostanziali al connubio tra ideologia ed estetica architettonica. L'appropriazione creativa da parte di questi regimi ha agito anche alla scala della città, predisponendo sia composizioni monumentali che realizzazioni meno caratterizzate, fino a utilizzare linguaggi prettamente moderni. Questa eredità pone rilevanti complessità nell'assegnazione del giudizio di valore ai fini del recupero architettonico per mezzo del quale occorre privilegiare ‘caso per caso' i significati originari.
Diradamento e assemblaggio: la costruzione dello spazio pubblico fascista
Authors: Semprebon Gerardo
Published: May 2023

Il rapporto tra architettura e potere trova nel periodo fascista una delle sue più intense manifestazioni, sia in termini di spazialità che in termini di espressività. Questo testo affronta il tema dello spazio aperto pubblico all'interno dei tessuti edilizi, proponendo due chiavi di lettura: la teoria del diradamento di Gustavo Giovannoni e l'assemblaggio metafisico rilevabile nell'estetica di Giorgio De Chirico. Vengono dapprima sintetizzati alcuni passaggi chiave che orientano la cultura del progetto nel ventennio fascista; successivamente, i due approcci sono presentati attraverso una ri-lettura teorico-artistica. In conclusione, si apre una riflessione sul carattere di resistenza degli spazi pubblici oggi e sulla permanenza di una qualità urbana introdotta nel primo dopoguerra.
Milano e il Lambro: il fiume in città e la possibile gestione di un progetto di spazi aperti
Authors: Longo Antonio
Published: May 2023

Lo studio di fattibilità ReLambro per il sistema degli spazi aperti e la connessione ecologica della valle urbana del fiume Lambro Milanese, sviluppato a partire dal 2012, ha portato attenzione sul tema del fiume in città e generato diverse iniziative di progettazione e interventi lungo il corso del fiume e nell'ambito dell'est milanese, oggi ancora in corso. Promosso da ersaf, insieme al Politecnico di Milano, al Comune di Milano e ad altri partner su finanziamento di Fondazione Cariplo, lo studio è divenuto parte del programma di sviluppo dei Contratti di fiume coordinato dallo stesso ente regionale, e ha quindi rappresentato un campo di sperimentazione e di osservazione delle modalità di progetto e di gestione della politica regionale, evidenziandone limiti e potenzialità.
Beyond the limits of the city. Ten Commandments for protection against pandemic risk
Authors: Bedini Maria Angela , Bronzini Fabio
Published: May 2023

The goal of this contribution is to adapt urban planning to the pandemic context. The methodology starts from the strategic objectives set at the European level by the Next Generation eu Plan and translates them into coherent goals at the urban level. The work results consist of ten fundamental choices (ten ‘commandments'): operational proposals to modify the current urban planning process, up to establishing an Urban and Territorial Plan for Pandemic Protection. In the conclusions, it is noted that to achieve the objectives, it is necessary to go beyond the limits imposed by inequalities, discrimination, urban and territorial imbalances, and the arrogance of predators of air, water, land, environment, and freedom.
Improving ecological connectivity assessments with transfer learning and function approximation
Authors: Catchen Michael , Lin Michelle , Poisot Timothée , Rolnick David , Gonzalez Andrew
Published: May 2023

This is a conference paper presented at the ICLR 2023 "Machine Learning for Remote Sensing" workshop.Protecting and restoring ecological connectivity is essential to climate change adaptation, and necessary if species are to shift their geographic distributions to track their suitable climatic conditions over the coming century. Despite the increasing availability of near real-time and high resolution data for landcover change, current connectivity planning projects are hindered by the computational time required to run connectivity analyses at realistic geographic scales with realistic models of movement. This bottleneck precludes application of optimization algorithms to prioritize ecological restoration to maintain and improve connectivity. Here we propose we can make progress toward overcoming these challenges using machine-learning methods. Our proposed methods will enable rapid optimization of connectivity prioritization and extend its application to many more species than is currently possible. We conclude by illustrating how this project will contribute to efforts to apply connectivity conservation using an example of ongoing restoration in southern Québec.

Ökológiai kérdések a képzőművészetben: Az ökológiai szemlélet megjelenése és alakulása a 20. és a 21. századi művészeti gyakorlatok tükrében
Authors: Egervári Júlia , Papp Sándor
Published: May 2023

Jelen tanulmány középpontjában az ökológia és a képzőművészet – különösen a vizuális, helyspecifikus, installatív és performatív projektek – kapcsolata áll. A képzőművészet és az ökológia kapcsolatát irodalmi forrásokra és aktuális kép‑ zőművészeti kezdeményezésekre alapozva vizsgáltuk meg. Először az ökológia kifejezés jelentését fejtjük ki, összefoglalva a jelenlegi globális ökológiai válság elemeit. Ezt követően a XX. század második felétől napjainkig számos művészeti gyakorlatot, művészt és művészeti projektet tekintünk át, melyek különböző módon foglalkoznak ezekkel a kérdésekkel, bemutatva azt a szemléletváltozást, amely a természethez, a környezethez, az ökológiához és az ökológiai válsághoz való viszonyulásban következett be, valamint az ember szerepét ebben a folyamatban.
Módszertani javaslatok a fényszennyezés problémakörének erdei iskolai feldolgozására
Authors: Kopasz Adrienn Réka
Published: May 2023

A környezeti nevelés a formális oktatás keretei között, szervezett programok segítségével igyekszik céljait megvalósítani. A természet egyéni motivációk alapján történő felfedezése, a szabad explorációs élmények ugyanakkor fontos szerepet játszanak az egyén környezethez fűződő viszonyának kialakításában, így fontos lenne kötetlenebb, kevésbé formális keretek közt lehetőséget biztosítani a diákok számára az ilyen jellegű megfigyelésekre. Ehhez az erdei iskolai foglalkozások jó lehetőséget nyújtanak. A fenntarthatóság pedagógiája beépülve az intézmé‑ nyes oktatás keretei közé lehetőséget biztosít arra, hogy a felnövekvő nemzedék fenntartható társadalomban élhessen. Az erdei iskola a természeti környezetbe integrált szinergikus megfigyelési‑tanulási‑észlelési‑érzékelési rendszerben teszi lehetővé a fenntarthatóság elveinek elsajátítását. Ebben a rendszerben a fény szennyezés kérdésköre a globális problémák közt kerül elemzésre. Így megalapozható a társadalmi felelősségvállalás és elköteleződés a fenntartható jövő iránt, ami feltételezi, hogy a tanulók képesek lesznek mérlegelni a cselekvési lehetőségeiket ezen a területen. A tanulmányban szereplő foglalkozástervek lehetőséget nyújtanak néhány jó gyakorlat kipróbálására a fényszennyezés problematikájának témakörében.
A pedagógiai értékelés kiegészítése elektrofiziológiai jelek követésével

Az EEG‑eredmények olyan többletinformációval szolgálhatnak a tanulókról, amely kiegészíti a feladatlapok eredményét, felhasználhatók arra, hogy ne csak azt tudjuk meg egy tanulási folyamat végén, hogy a feltett kérdésekre mennyire jól sikerültek a tanuló válaszai, hanem azt is, hogy a tanulási folyamat alatt a tanuló motivált volt‑e, vagy inkább zavart, mennyire unta a feladatot, és mikor fáradt el egy teszt alatt. Az EEG‑mérések kiértékelésénél nehézséget okoznak a mérés alatti műtermékek, emiatt olyan feladatoknál alkalmazható jól az eljárás, amelyek kevés mozgással járnak. Az EEG‑aktivitás egyéni jellemzői miatt a hasonló feladatok alatti regisztrátumok spektrális jellemzői nagyon eltérőek lehetnek, ennek figyelembevételéhez további mérések szükségesek.
Türkiye’de Yaşayan Vegan - Vejetaryen Bireylerin Beslenme Durumlarının Kıyaslanması Üzerine Pilot Bir Çalışma
Authors: Balcı Tuğçe Nur , Göktaş Zeynep
Published: May 2023

Aim: Vegan and vegetarian diets are in an increasing trend worldwide in recent years. Vegan/vegetarian diets, which are known to have positive effects on health, may result in nutrient deficiencies if they are not balanced. It is important to determine the nutritional status of vegan and vegetarian individuals, whose number is increasing in Turkey, in order to build national recommendations. This study was conducted as a pilot study to determine the energy and nutrient intake of vegan/vegetarian individuals living in Turkey.
Subjects and Method: A total of 285 volunteered vegan/vegetarian individuals aged 19-64 years participated in the study. The general information and vegan/vegetarian status of the participants were questioned with an online survey. After answering the survey, 38 volunteered participants kept a consecutive three-day “24-h food record” and shared it with the researchers. The energy and nutrient intakes of the individuals and the rates of meeting their requirements were calculated. Chi-square test of independence was used to compare individuals’ vegan/vegetarian status by gender and general knowledge by vegan/vegetarian status; independent sample t-test and Mann-Whitney U test were used for age, energy and nutrient comparisons between groups.
Results: The majority of the participants were female (79.3%), holding at least a bachelor’s degree (89.5%), and had a normal BMI value (72.6%). Rate of vegan and vegetarian participants that were not able to meet their energy and nutrient requirements were as follows respectively: 76.5%, 85.7% for energy (kcal); 52.9%, 95.2% for carbohydrate (%); 100%, 52.4% for vitamin B12; 64.7% 61.9% for folate; 94.1%, 76.2% for calcium; 64.7%, 76.2% for iron; and 88.2%, 71.4% for zinc.
Conclusion: It has been observed that vegan and vegetarian individuals living in Turkey are at risk of several nutrient deficiencies. Considering the increasing trend of vegan and vegetarian diets, it is necessary to determine the nutritional status of individuals on a large scale and to raise awareness of individuals. It is important that the recommendations specific to vegan/vegetarian individuals in national nutrition guidelines are implemented by vegan/vegetarian individuals, health professionals and food service providers.
