Authors: CIOLEA Daniela Ionela , ILCIUC Oana Daniela , BERCA Marius
Published: January 2023

Artykuł przedstawia oryginalne badania związane z odzyskiwaniem miedzi ze ścieków przemysłowych. Celem badań eksperymentalnych jest odzyskiwanie sproszkowanej miedzi metalicznej ze ścieków o niskiej zawartości jonów miedzi metodą cementacji za pomocą złomowej elektrody żelaznej oraz do obliczenie wydajności cementacji miedzi, na którą wpływają następujące parametry: początkowe stężenia jonów miedzi, wartości pH i czas kontaktu. Eksperymenty obejmowały odzysk miedzi z przemysłowych roztworów z wykorzystaniem odpadów żelaza metodą cementowania, bez zużycia innych odczynników lub energii. Plan eksperymentu obejmował trzy różne stężenia CuSO4: dla każdego roztworu o przygotowanym stężeniu: 0,5% CuSO4, 1% CuSO4 oraz 3% CuSO4 , przeprowadzono eksperymenty laboratoryjne dla dwu wartości odczynu pH (naturalne pH uzyskane przez rozpuszczenie CuSO4 * 5H2O w wodzie, pH=2 (regulacja 0,1 M roztworem kwasu siarkowego). Optymalne warunki dla każdej receptury zostały określone na podstawie danych eksperymentalnych. W badaniach wykorzystano spektrometry WTW Multi 350i i AAS ZEEnit 700 Spektrometr Analytik Jena. Przeprowadzono obliczenie wydajności pozyskania proszku miedziowego dla każdego dnia doświadczenia i dla każdej receptury. Dane eksperymentalne doprowadziły do wniosku, że optymalnym wariantem dla badania jest: stężenie 0,5%, przy początkowe pH 3,6 po 3 dniach doświadczenia i wydajność 95,23%.

Published: January 2023

Zanieczyszczenie morza tworzywami sztucznymi powoduje niekorzystne skutki dla globalnego środowiska i ekosystemów morskich, szczególnie w morskich obszarach chronionych. Jednak niewiele wiadomo na temat wpływu plastikowych odpadów morskich na funkcjonowanie ekosystemów morskich, dobrostan ludzi, społeczeństwo i gospodarkę. Wybraliśmy Morski Obszar Chroniony Phu Quoc (Phu Quoc MPA), aby uzyskać wgląd w aktualne morskie odpady plastikowe jako pierwszy krok w kierunku zrozumienia ich wpływu na środowisko i różnorodność biologiczną w regionie. W badaniu tym zastosowano analizę danych wtórnych, częściowo ustrukturyzowane wywiady, pomiary terenowe i metodę transektu linii kwadratowej w dążeniu określenie wpływu czynników. Badania wykazują, że morskie odpady plastikowe usuwane w Phu Quoc MPA pochodziły z różnych źródeł, w tym z rzek, strumieni, kanałów, dostawców usług turystycznych i obszarów rozwoju akwakultury morskiej. Obfitość makroplastiku na plażach wynosiła w przybliżeniu od 1,109 do 0,248 sztuk/m2 (co odpowiada 0,082 ± 0,021 kg/m2). Większość makroplastiku to tworzywa sztuczne jednorazowego użytku, które stanowiły ponad 82%. Średni rozmiar wynosił około 14,932 ± 1,846 cm dla przedmiotów mniejszych niż 30 cm. Pozostałe to torby foliowe HDPE i odpady z tworzyw sztucznych. Należy powstrzymać wyrzucanie makroplastiku i mikroplastiku, aby zachęcić do zrównoważonego gospodarowania odpadami w regionie.

Published: January 2023

W obliczu zmian klimatu, globalnego ocieplenia i wyczerpywania się zasobów kopalnych, takich jak węgiel, ropa naftowa itp., rozwój czystych źródeł energii stał się światowym trendem. Czyste źródła energii są obecnie eksploatowane i silnie rozwijane na całym świecie, w tym: energia słoneczna, energia wiatru, energia geotermalna, energia fal oceanicznych, energia geotermalna, energia biomasy. Wietnam położony jest w tropikalnym klimacie monsunowym, z linią brzegową rozciągającą się na ponad 3000 km, więc potencjał rozwoju energetyki wiatrowej w Wietnamie jest niezwykle duży, co przyciąga wiele inwestycji w projekty wiatrowe w kraju. Przykładem omawianym a artykule jest elektrownia wiatrowa nr 3 – prowincja Soc Trang. Jak dotąd wspomnieliśmy tylko o korzyściach i czystych, odnawialnych aspektach energii wiatrowej, ale niewielu wspomniało o wpływie elektrowni wiatrowych na środowisko i zdrowie ludzi, a zwłaszcza emisji hałasu podczas pracy. W artykule wykorzystano oprogramowanie WindPro 3.1.597 do określenia stopnia oddziaływania hałasu emitowanego przez turbiny wiatrowe podczas pracy elektrowni wiatrowych, oceniając tym samym jego wpływ na zdrowie ludzi, lokalnych mieszkańców mieszkających w pobliżu obszaru objętego projektem i zaproponować środki zaradcze.

Negative responses to the learning process and the high cost of buying quotas are problems that arise due to the implementation of online learning during PJJ. The purpose of this research is to analyze strategies for using a combination of distance learning tools/media that are effective and low-cost in the teaching-learning process in science courses. This survey research uses a closed questionnaire as a research instrument. Questionnaires were distributed to 112 PGSD students. The questions asked were 10 items related to network and internet access, and the PJJ tools used. The data obtained were analyzed using descriptive statistics. We found the fact that the University of Mataram has provided good e-learning for use in online learning. The vicon media and social media that are most frequently used sequentially are Google Meet (96.4%) and WA (99.1%). Therefore, the online tool/media that we recommend is the use of a combination of the three tools/media together with the surrounding environment as a Natural Laboratory in science learning. This recommendation is not only relatively cheaper in cost, but also has the potential to develop aspects of students' knowledge, attitudes and science process skills.

Published: January 2023

Se estableció un experimento en campo con el objetivo de evaluar el efecto de dos sistemas de siembra, tres densidades y tres cultivares, sobre los caracteres ecofisiológicos y numéricos del rendimiento de semilla de haba var. Mayor. Los tres cultivares de haba (Amarilla, Diamante y Monarca) fueron sembrados en parcelas de tres surcos de 3 m de largo y separados a 0.8 m (sistema tradicional: ST) y a 0.4 m (sistema alternativo: SA) y en tres densidades de población (5, 10 y 15 semillas m-2). Para lograr la densidad deseada se depositaron dos semillas cada 25, 12.5 y 8 cm (ST) y cada 50, 25 y 16 cm (SA). El diseño experimental fue un diseño de bloques completos al azar con cuatro repeticiones en serie. Los resultados mostraron efectos significativos para sistemas de siembra, densidad y cultivares. El SA obtuvo la mayor producción de biomasa y rendimiento de grano respecto del ST. Aumentar la densidad de población incremento el rendimiento de semilla debido a un mayor número de semillas por unidad de superficie y a un mayor número de vainas por m2. Mostrando que la variabilidad mayor en este experimento se debió al incremento en las densidades de siembra, seguido por las distancias entre hileras (SA 40 cm) y (ST 80 cm). El genotipo Monarca obtuvo el mayor rendimiento de semilla, mientras que Amarilla presentó un incremento en peso de 100 semillas. Se observó que cada cultivar presentó un comportamiento distinto para la generación del rendimiento.

El uso de silicio (Si) y cloro (Cl) permite que las plantas incrementen favorablemente el crecimiento y desarrollo, ya que contribuyen al aumento del peso seco de las plantas y biosíntesis de clorofila, así como la resistencia a factores bióticos y abióticos. La investigación se realizó para esclarecer el resultado que ocasiona la aplicación de Si y Cl en el crecimiento de plántulas de pepino y tomate. Para ello, se sembró pepino ‘Paraiso F1’ y tomate F3 en charolas de poliestireno con 242 cavidades rellenas de peat moss. Se utilizó el diseño experimental de bloques completos al azar, donde los tratamientos fueron: 20, 30 y 50 mg L-1 de Si 20, 30 y 50 mg L-1 de Cl, 20:20, 30:30 y 50:50 mg L-1 de Si:Cl un testigo absoluto y cuatro repeticiones por tratamiento. Las variables de respuesta fueron verdor foliar, altura de planta, área foliar, peso seco de la parte aérea y de raíz en plántulas de pepino y tomate. En plántulas de pepino, el verdor foliar se incrementó 18.7% y 4.6% con 20 y 50 mg L-1 de Si y Cl, respectivamente. La combinación de 20:20 mg L-1 de Si:Cl aumentó un 30.2% la biomasa de la parte aérea. Mientras que, en plántulas de tomate, tratadas con 30 mg L-1 Si y en mezcla con Cl a concentración 30:30 mg L-1 su altura fue de 31.9% y 25.1% con respecto a las plántulas testigo. La biomasa seca de raíz se aumentó significativamente con la aplicación de Si (20 y 30 mg L-1), Cl (20 y 50 mg L-1) y en combinación 30:30 (mg L-1).

Los brasinoesteroides son fitohormonas esteroidales que se han utilizado ampliamente en la agricultura, se han realizado pocos estudios sobre el efecto que pueden tener para inducir la formación de raíces en esquejes de arándano (Vaccinium corymbosum). El objetivo de esta investigación fue evaluar el efecto del 24-epibrasinolide (24-EBL) a distintas concentraciones (0, 20, 40 y 60 μg L-1) y del sustrato sobre el enraizamiento de esquejes, se utilizó mezcla de arena de río y tezontle (AT), turba (Peat Moss®) y perlita (PMP), mezcla de fibra de coco y perlita (FCP), turba (Peat Moss®) (PM) y fibra de coco (FC). Las variables evaluadas a los 30 días después de establecido del experimento, fueron porcentaje de supervivencia (%SE), porcentaje de esquejes enraizados (%ER), número de raíces por esqueje (NR), longitud de raíz principal (LRP) y longitud total del sistema radicular (LTR). Los datos obtenidos se sometieron a análisis de varianza y comparación de medias con la prueba de Tukey. Los resultados mostraron que los esquejes de arándano con 24-EBL a una concentración de 60 μg L-1 en sustrato de AT presentan 84.7% de supervivencia y 67.76% de esquejes enraizado. Los esquejes expuestos a 24-EBL a una concentración 40 y 60 μg L-1 insertada en sustrato de mezcla de AT presentaron una mayor longitud de raíz y más raíces por esqueje en comparación con otros sustratos. Se concluye que el 24- EBL induce la formación de raíces en esquejes de plantas de arándano en sustrato de AT.

En la actualidad, los suelos agrícolas están afectados por salinidad debido al uso excesivo de fertilizantes y la mala calidad del agua para el riego agrícola. En la actualidad, los productos a base de silicio (Si) se están aplicando para ayudar a la sostenibilidad de la agricultura; además, el Si beneficia a las plantas a tener mayor tolerancia a plagas y enfermedades, ayuda contra la toxicidad por metales pesados y actúa contra el estrés hídrico y salino. Por lo tanto, el objetivo del estudio fue evaluar el efecto del silicio como atenuante de la salinidad en la germinación de semillas y crecimiento inicial de plántulas de tomate. El trabajo se realizó en el laboratorio de Germoplasma de la Universidad Autónoma Baja California Sur. Las variedades de tomate seleccionadas fueron: cherry (Solanum lycopersicum var. Cerasiforme), bola (Solanum lycopersicum var. Floradade) y saladette (Solanum lycopersicum var. Río Grande). El diseño experimental fue completamente al azar con arreglo factorial de 2 x 3, donde el factor A fueron las concentraciones salinas de cloruro de sodio (NaCl) (0, 25, 50 mM) y el factor B, las diluciones de silicio (0, 1, 2 mM). Cada tratamiento incluyó cuatro repeticiones de 25 semillas cada una. Los cultivares de tomate mostraron efectos diferentes respecto a la salinidad. El cultivar cherry mostró disminuciones en sus variables germinativas al incrementarse la salinidad, lo que indica que los cultivares Floradade y Río Grande son más tolerantes a salinidad. En este sentido el silicio presentó un efecto protector en la interacción (NaCl + Si), mostrando efectos positivos al incrementar las variables evaluadas.
Ten Versions of Seeing the Nightscape in Seoul
Authors:   The Association Of Korean Cultural And Historical Geographers, Hong Keumsoo
Published: January 2023

The cultural landscape has served as a means of exploring the repertoires of cultural areas and cultural diffusion. Recent discussion features the thicket of analogies identified with new cultural geography as well as the rhetoric of performativity decreed by the affective turn. However there remains a critical caveat in that landscape interpretation has been pursued on the sole backdrop of daytime. Nighttime scenery has been muted with few attempt to interpret the real and symbolic meanings and consistently marginalized in landscape studies. It is the advent of 24-hour life style in tandem with the post-industrial consumer society that allows cityscape to see the light of night. In this article I try to test the plausibility of D. Meinig’s ten versions of an ordinary landscape by loitering along the streets of Seoul in an attempt to look into a diversity of everynight urban landscapes amid floods of incandescent electric lights. The journey conforms that Seoul’s nightscapes have multiple meanings of nature, habitat, artifact, system, problem, wealth, ideology, history, place and aesthetic in line with Meinig’s conceptualization. It is time to further the discourse by relying on such highly insightful metaphors as text, theatre, carnival, spectacle, ways of seeing, symbol, sign and icon.
Why Do Locals Host Tourists?: Various Local Hosts’ Reasons for Choosing Airbnb Experiences and Their Motivations for Hosting
Authors:   The Association Of Korean Cultural And Historical Geographers, Kim Jurak
Published: January 2023

This study attempted to understand how local hosts, who greet tourists on an online platform, got to know the platform and what motivated them to host, and as a result, it identified a variety of hosts accordingly. Until now, ‘new urban tourism,’ in which tourists are interested in locals’ daily lives, has been considered a tourist-led phenomenon, so research on the role of local people has not been fully conducted. However, local people are already key actors in local tourism through online platforms and their role in post-COVID-19 tourism is expected to become more important. As a result of the study, the way local people know and participate in the platform and the motivation for hosting are interrelated, and the effects of hosting vary depending on it. With research on tourists, research on local people who were consumers of local tourism in the past but become suppliers is necessary to comprehensively understand the changes in tourism and regions.
In Search of the Origin of Ch’ŏnhado, a Traditional Korean Map of the World
Authors:   The Association Of Korean Cultural And Historical Geographers, Yoon Hong-key
Published: January 2023

Ch’ŏnhado is a unique traditional Korean world map which reflects the Korean geomentality of the world. Some researchers postulated that this map was developed after the introduction of European maps of the world to Korea and concluded that Korean world maps were therefore influenced by these European maps. However, this research has found that ch’ŏnhado was independently developed by Koreans and does not reflect any influences from European maps of the world. Ch’ŏnhado is a folk-geographic map reflecting Koreans’ understanding of the world during the premodern period.
A Place-centered Approach for the Integrated Nature-Culture Management of World Heritage in the Antropocene Era
Authors:   The Association Of Korean Cultural And Historical Geographers, Kim Sook Jin
Published: January 2023

The nature-culture dichotomy inherent in the World Heritage Convention seemed to be overcome but incomplete when cultural landscapes were introduced as a new type of World Heritage in 1992. In recent years, IUCN and ICCROM, the World Heritage advisory bodies, are actively promoting an integrated nature-culture management approach through ‘Connecting Practice’, ‘Nature-Culture Journey’, World Heritage Capacity Building Program, and ‘Panorama Solution’. The integrated nature-culture management approach encompasses the wider environment, culture and local community surrounding the heritage site, which is equivalent to a place-centered approach. The extension of the world heritage, Røros Mining Town and the Circumference, not only contributes to recognizing and preserving the entanglement and coexistence of nature and culture, but also provides an opportunity to recognize another humanity, Sámi and their sustainable way of managing nature in the Antropocene era.
A Multiscalar Approach to the Geopolitical Division of Ukraine Focusing on the Russo-Ukrainian Relationship: How does the Dnieper Geopolitically Divide Ukraine?
Authors:   The Association Of Korean Cultural And Historical Geographers, Lee Dong-min
Published: January 2023

Ukraine has been geopolitically divided along the Dnieper: the pro-European Union west region versus the pro-Russia east. Such a geopolitical division has played a critical role in recent Russia-Ukraine relations and conflicts, including the 2014 Crimean Crisis, the Donbas War, and the Russo-Ukrainian War. This study casts a question as to why Ukraine shows a noticeable geopolitical division. Geographical distances or proximities do not provide a proper answer to that question; for example, eastern Ukraine was the spatial background of the spread of Ukrainian nationalism in the 19th century. In this respect, this study adopted the multiscalar approach to analyze various scalar factors and actors and their relations that influence the geographical division of Ukraine. The results of this study suggest that multiscalar factors and actors, including the change of Ukrainian territories and the scalar differences in the influence of Russia caused by the territorial change, the geographical scale of Ukrainian industry and economy, the state-building of Ukraine in the post-Soviet era, and neighboring states’ influences and diplomatic strata and their interrelations, The results of this study may provide significant contributions to an in-depth understanding of the geopolitical characteristics of Ukraine and international and geopolitical issues related to the country.

Published: January 2023

Estudos internacionais têm demonstrado que o acompanhamento regular da qualidade das imagens na radiografia e na mamografia tem impacto positivo nos programas de controle de qualidade (CQ) dessas modalidades de diagnóstico. Por serem realizados com menor periodicidade e poderem ser executados sem a presença de um especialista, estes ensaios exigem o uso de simuladores próprios e metodologias particulares que permitam sua aplicação rotineira na prática clínica. Neste sentido, o presente trabalho avaliou a implementação na prática clínica dos ensaios de controle de qualidade remoto propostos pela Agência Internacional de Energia Atômica (IAEA Human Health Series – Nº39). Simuladores recomendados pela publicação da IAEA foram fabricados utilizando materiais disponíveis no mercado nacional (placas de acrílico, cobre e alumínio). Imagens destes simuladores foram adquiridas utilizando sistemas digitais e de radiologia computadorizada, em equipamentos de radiografia convencional e mamografia. Na análise das imagens foi empregado o programa desenvolvido e disponibilizado pela IAEA (ATIA), que quantifica de forma automática métricas avançadas de avaliação de qualidade de imagem, como SNR, SDNR, MTF, NNPS e índice de detectabilidade (d’), além de identificar artefatos na imagem e gerar mapas de variância. Os resultados obtidos indicam que é possível avaliar métricas quantitativas de qualidade de imagem ainda não incorporadas na rotina tradicional de CQ com simuladores de baixo custo e viável a partir do material disponível no mercado nacional. A avaliação periódica destas métricas, com periodicidade semanal ou mensal, deve facilitar a identificação de mudanças de desempenho dos sistemas de imagem, contribuindo para a implementação de práticas corretivas antes mesmo do controle de qualidade anual tradicionalmente exigido pelas normativas da ANVISA.

Research on conspiracy theories has revealed a significant association between conspiratorial thinking and education. The relationship is complex, however, and has so far been limited primarily to investigations of personal psychological attributes. This paper argues, instead, in favour of a broader social research perspective, specifically, one informed by a dialectical materialist philosophy. A secondary analysis of publicly available international data sourced from economic institutions and other organisations on conspiratorial belief, educational performance measures, unemployment, inequality and corruption perception was carried out. Conspiratorial belief was taken as a collective public epistemological phenomenon across countries, to explore the role of contemporary education systems across societies, and the degree to which they are successfully nurturing an effective form of critical thinking. A dialectical materialist philosophical approach was instrumental in formulating the study scope and interpreting the findings, given the use of countries as the fundamental unit of analysis. Multiple regression analysis was used to examine the relationship between belief in conspiracy theories and education, taking into account social context using unemployment, inequality, and corruption as control variables. The findings showed that the relationship between conspiratorial thinking and education held at the societal level, and was mediated by additional social factors. The paper goes on to argue, by virtue of the nature of the mediators, that education systems generally tend to fall short of effective and socially-engaged forms of critical pedagogy.

Authors: NORDITO S QUIMBO
Published: January 2023

Athletic participation has been in a tight spot when juxtaposed with academic performance for decades of debates and empirical studies. Athletic participation critics would claim that it is detrimental to the performance of the students inside the classroom or "outside the court." This would often be opposed by sports enthusiasts claiming that this type of engagement hones the students holistically. This paper attempted to confirm that the existence of the time management variable can help boost the positive relationship between athletic participation and academic performance among 96 student-athletes in San Isidro, Leyte. High positive correlations occurred between athletic participation and time management; time management and academic performance; and, athletic participation and academic performance. This study also confirmed what is considered important and urgent by this group in terms of student-athlete activities using the Eisenhower Matrix of the ABC Time Management Analysis. Finally, it can be deduced from the time allocation results that the more the student-athletes stick to a time allocation effective to them, the better the results are in all three aspects being studied.

One of the techniques to speed up work on a tanker repair project by increasing working hours which is often referred to as overtime hours with two approaches to speeding up work on a project evaluated technically and economically compared by researchers. Researchers evaluate project work and calculate the workforce involved in tanker repair. Researchers perform calculations for each part of the workforce in the ship repairment process, and also analyze the scheduling of each part of the workers that have been prepared by the company.

Mid-term functional outcome after distal Achilles tendon rupture anchoring screw repair in elderly osteopenia as a reliable technique: A case report
Authors: Wardhana Teddy Heri , Aziz Mukhlis
Published: January 2023

The management of distal Achilles tendon rupture is still controversial, especially in elderly patients, due to poor bone quality and tendon stump integrity. One of the proposed repair techniques is by using an anchoring screw. Here we report the mid-term follow-up of two patients with distal Achilles tendon rupture treated with an anchoring screw. Two elderly males in their sixties came to the outpatient clinic with similar complaints of intermittent pain, reddening, and ankle swelling after falling. Both patients were diagnosed with distal Achilles tendon rupture and were treated with open repair using a Krakow suture and anchoring screws. Functional outcome evaluation postoperatively found a good outcome. Previous studies have shown that repair with the anchoring technique is better biomechanically than with ordinary sutures. Repairs with this technique can withstand greater forces and loads before they fail. An anchoring screw repair technique for total distal Achilles tendon rupture repair provides good results in elderly with osteopenia.
