Authors: Farias Eugênio David Ermerson , Marques Farias Guilherme , Holanda de Castro Marco Aurelio
Published: December 2023

O estudo em questão apresenta a implementação do algoritmo PSO (Particle Swarm Optimization) com a finalidade de otimizar o trabalho de redes coletoras de esgoto de modo a reduzir o custo de implantação da mesma, tendo como variáveis de decisão a topografia do terreno e a classificação dos trechos em ponta seca ou não. O modelo de otimização foi aplicado em uma malha hipotética contendo 12 trechos e 9 singularidades. O processo de otimização do PSO resultou em um custo ótimo de R$ 30.076,92, resultando em um erro relativo de 4,42% em relação ao custo ótimo global para o problema, que é de R$ 28.801,52, o que indica um desempenho satisfatório. Todavia, ao se comparar o referido resultado com a solução trazida pelo AG (Algoritmo Genético) implementado para a mesma malha por Rodrigues et al. (2020), percebe-se um desempenho inferior do PSO, uma vez que o AG conseguiu alcançar uma solução ótima de R$ 28.894,35, sendo esta mais próxima do custo ótimo global.

A destinação final inadequada dos Resíduos de Construção e Demolição (RCD) acarreta graves problemas para a população, tais como contaminação de cursos d’água e proliferação de doenças. Dessa forma, este artigo objetiva a aplicação de um Sistema de Informação Geográfica (SIG) para identificar a correlação entre os pontos de descarte irregular de RCD, a população e a renda média familiar, indicando possíveis áreas para instalação de Ecoestações no município do Cabo de Santo Agostinho, Pernambuco, Brasil. A metodologia fundamentou-se na análise de 85 pontos de descarte irregular de RCD, levantados em 2016. Em seguida, procedeu-se à inserção desses dados em ambiente de SIG, por meio do software livre QGIS 2.18.0, para realização de análises espaciais de correlação. Os resultados mostram que 57,65% dos descartes irregulares encontram-se em áreas de baixa renda. Observa-se que 49,41% dos pontos encontram-se em áreas pouco adensadas, demostrando que essas áreas são mais propensas a receber descartes irregulares. Por fim, a pesquisa apontou a necessidade de instalação de 10 (dez) Ecoestações no município.

Authors: Marciana Barbosa de França Josefa , Capelo Neto José , Clemente Allan , Paulino Walt Disney , Almada Teixeira Zulene
Published: December 2023

O presente estudo focou no aporte de cargas dos macronutrientes (NT e PT) e na influência da estratificação do Reservatório Castanhão em relação à transposição de água do Canal da Integração até o ponto a jusante do Reservatório Curral Velho. A metodologia de análise baseou-se na análise da perfilagem da coluna de água e na aplicação de testes estatísticos. Verificou-se um padrão sazonal da variável da temperatura, com processos de estratificação no primeiro semestre e desestratificação no segundo. O OD e pH apresentaram estratificação irregular. A CE e os SDT não estabeleceram nenhum padrão. Identificou-se que existem diferenças significativas entre a temperatura, OD e pH, em relação aos pontos Castanhão e CIN21, o que ocasionou a desoxigenação nos pontos CIN21 e CIN08, e a oxigenação natural foi constatada a 43,50km. Com relação às cargas de nutrientes NT e PT, essas têm tendência a oscilar conforme a vazão liberada a partir do gerenciamento do reservatório.

Current directions of inclusive development of small and medium-sized enterprises of Ukraine in the agricultural industry
Authors: Didukh Serhii , Minina Victoria
Published: December 2023

The article is devoted to studying the critical role played by small and medium-sized enterprises (SMEs) in forming the system of inclusive development of the agro-food industry in Ukraine. The urgency of this issue becomes evident in the conditions of a full-scale war and the need for post-war reconstruction. To achieve this goal, the work uses various research methods, including survey-analytical, abstract-logical generalization, graphic method, system analysis, and synthesis. In this work, the institutional prerequisites of the concept of inclusive development were determined, strategies in this direction were outlined, and scientific approaches to interpreting the term "inclusive development" were generalized. We offer a conceptual model of the inclusive development of SMEs in Ukraine and have identified the role of SMEs in forming an inclusive environment of the agro-food sector.
The development of SMEs in the agri-food industry should be based on inclusiveness, which involves including different groups of society, ensuring equal opportunities, and supporting participation in entrepreneurship. The agri-food sector requires the ability of SMEs to develop sustainably and innovate. Inclusive development should focus on creating conditions for innovative growth, which will contribute to the competitiveness of enterprises. It is essential to emphasize the role of SMEs in fulfilling the social mission, mainly promoting the preservation and development of regional communities, and ensuring quality products and employment. Effective inclusive development involves establishing partnerships between SMEs, the public sector, and government institutions and ensuring access to financial, technological, and educational resources. The inclusive development of SMEs in the agri-food sector must consider gender aspects, promoting equal access of women and men to entrepreneurial activities. The article also analyzes the existing and prospective state support mechanisms for SMEs in wartime. We consider how SMEs can influence the country's post-war reconstruction in the context of the agri-food industry. Our further research will be aimed at substantiating the main directions of SME development in the conditions of an inclusive economy, improving the toolkit for assessing the inclusive development of SMEs and substantiating the model of inclusive development of SMEs in the agri-food industry.

Authors: Mahida Archana , Tandel Y. N , Patel D. P , Kumar Manish
Published: December 2023

Biofortification is a global-scale agricultural approach that can improve human nutrition. Agronomic biofortification is viewed as a quick-fix and supplemental approach. Agronomic biofortification, especially foliar application, is highly effective for zinc and iron. A field experiment on agronomic biofortification of zinc and iron micronutrients in mango cv. Kesar was carried out in 2016-2017 at the Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat). The experiment was arranged in a completely randomized design (CRD) with three replications containing 9 treatments. The results show that foliar application of ZnSO4 and FeSO4 (0.5% each) resulted in higher N (48.73 mg/100 g) and K (94.17 mg/100 g) in the pulp and P (0.056%) in the peel of mango. The iron (Fe) and zinc (Zn) contents in pulp and peel were highest in treatment T9 (0.50% FeSO4 + 0.50% ZnSO4), which was on par with those in treatment T8 (0.50% FeSO4 + 0.25% ZnSO4).

The evaluation of different mango varieties was conducted during 2019-20 and 2020-21. The experiment was laid out in a randomized block design (RBD) with four varieties, namely, Ambika, Pusa Arunima, Kesar, and Dashehari-51, each replicated three times. The plants were spaced at 4x4 m intervals. The results obtained demonstrated significant variations in various parameters, ranging from minimum to maximum values. The canopy spread ranged from 1.77 to 7.49 m, stem girth from 16.67 to 40 cm, number of fruits per plant from 21 to 118, fruit length from 92.04 to 123.28 mm, fruit width from 56.02 to 77.41 mm, and fruit weight from 202 to 591 g. However, the number of primary branches (2-3) and plant height (1.54-4.35 m) were found to be nonsignificant. Based on the morpho-economic traits, Pusa Arunima appeared to be a superior variety in terms of tree morpho-economic traits, while others were considered moderate. Considering the average number of fruits per plant and fruit weight (g) over a two-year period, Pusa Arunima clearly outperformed the other three varieties in terms of yield. Furthermore, Pusa Arunima, Kesar, and Ambika exhibited more marketable fruit traits. These findings emphasize the significant diversity among the examined mango cultivars. Therefore, it is crucial to protect and preserve these valuable genetic resources for future breeding programs aimed at developing novel and commercially viable cultivars.

Published: December 2023

The current study demonstrates the influence of conventional and organic nutrient management practices on nitrogen use efficiency, growth, yield, and physiological and biochemical parameters in four rice varieties, namely, Jaiva, Ezhome 2, Jyothi and Uma. Growth parameters, grain yield per hill, and physiological and biochemical parameters were higher under conventional management for all rice varieties. Although the nitrogen use efficiency of each variety varied significantly with nutrient management practices, the variation was least in Jaiva (23.8%), which is the organic rice variety released by Kerala Agricultural University. The rice varieties Jaiva and Ezhome 2 showed consistency in the grain weight per panicle under both conventional (Jaiva- 4.57 g, Ezhome 2- 5.86 g) and organic (Jaiva, 4.24 g, Ezhome 2, 4.54 g) management. The soil nitrogen content at the tillering stage (0.66**) showed a significantly higher positive correlation with nitrogen use efficiency under organic management. The results of the study provide a better understanding of factors that can lead to a sustained yield in organic rice production in terms of nitrogen use efficiency.

Critical thinking is considered a comprehensive cognitive skill in problem solving and argumentation that needs to be possessed by students in the twenty-first century. This study mainly aims at investigating a teacher’s way of employing debate activities as an effective way to promote students’ critical thinking ability in EFL classroom, the type of CT skills manifested through the debating activity, and students’ perceptions toward the implementation of debate activities as a technique that can help them to think critically. The data were obtained through semi-interviews, classroom observations, and documents. One English teacher and the total of 12 students of high and low achievers in speaking performance were involved. The results revealed that Parliamentary Debate system employed happened to be exceptionally helpful to EFL teachers who intend to promote students’ critical thinking ability as students are constantly trained to construct arguments and strengthen their claim. However, the students admitted that having limited experience in debate practice is a major obstacle. Thus, more lessons and practices in constructing a good argument are needed. Furthermore, the quality of argumentation constructed by learners should be evaluated to prevent students from fallacies.

Published: December 2023

Badania przeprowadzono w latach 1997–1999 na polach Stacji Doświadczalnej w Tomaszkowie. Obiekt badań stanowiły trzy średnio późne odmiany ziemniaka, nawożone azotem w dawkach 30, 60 i 90 kg·ha-1 sposobem rzędowym (zlokalizowanym w redlinę podczas sadzenia) i sposobem powierzchniowo-rzutowym. Podczas okresu wegetacji, na trzy tygodnie przed zbiorem, dokonano oceny nasilenia antraknozy (Colletotrichum coccodes). W laboratorium określono skład ilościowy i jakościowy grzybów wyizolowanych z podstawy losowo pobranych łodyg ziemniaka. Podczas całego okresu badań odmiana Anielka charakteryzowała się istotnie niższym porażeniem przez C. coccodes w porównaniu do pozostałych odmian: Rywal i Salto, na których zanotowane indeksy porażenia wynosiły odpowiednio 18,5, 16,9 i 22,6% w kolejnych latach badań. Stwierdzono zróżnicowane nasilenie antraknozy na badanych odmianach w zależności od dawki nawożenia azotem. Najwyższe porażenie (27%) zanotowano w 1999 roku na ziemniaku nawożonym azotem w najniższej dawce 30 kg·ha-1. Porażenie roślin w kombinacji z nawożeniem zlokalizowanym w redlinę było istotnie niższe w porównaniu z nawożeniem powierzchniowym tylko w trzecim roku badań. Izolacja grzybów z podstawy losowo pobranych łodyg ziemniaka dowiodła licznego udziału grzyba C. coccodes wśród 479 kolonii — 35,5%. Najczęściej był on wyosobniany z odmiany Rywal. Pozostałe patogeny, reprezentowane przez gatunki z rodzaju Fusarium oraz Alternaria alternata, izolowano z łodyg badanych odmian rzadziej — po 8%. Niewiele więcej izolatów grzyba C. coccodes było na roślinach o najniższym nawożeniu, natomiast grzyby z rodzaju Fusarium oraz Rhizoctonia solani częściej zasiedlały łodygi roślin nawożonych azotem w dawce 60 i 90 kg·ha-1.

W 2005 roku założono doświadczenia polowe metodą bloków niekompletnych w Smolicach i Kobierzycach. Materiał badawczy stanowiły 22 linie wsobne kukurydzy szklistej (typu flint) oraz 21 linii zębokształtnych (typu dent). Nasiona wysiano na poletkach 5 m2 w rozstawie 75 × 18,6 cm. Na roślinach wykonano obserwacje cech bonitacyjnych: pylenia i znamionowania, a po zbiorach – pomiary cech użytkowych: długości kolby, liczby rzędów w kolbie, liczby ziaren w rzędzie, liczby ziaren w kolbie, masy kolby, masy osadki, procentowej zawartości suchej masy oraz masy ziarna z kolby. Otrzymane wyniki posłużyły do obliczenia trzech indeksów: indeksu wartości własnej IS, indeksu obcego IO, oraz indeksu ogólnego IOG. Wyliczono je w 2 wariantach: a). bez współczynników wag i b). z dodaniem do wzorów oszacowanych współczynników wartości ekonomicznej (wag poszczególnych cech). Ranking linii uwzględniający wagi cech wskazuje w większości przypadków na te same genotypy, dla których wyliczono indeksy bez współczynnika ważności cech. Po wprowadzeniu do obliczeń wag ekonomicznych otrzymano indeksy, które pozwoliły na wyłonienie najlepszych linii: S 50668-4, K 409, S 41798-1-2-2, S 50685, S 47225A. Wykorzystanie wag poszczególnych cech w indeksach, pozwala na lepszą charakterystykę linii i dzięki temu na efektywniejszy wybór linii.
Fuzarioza kłosów pszenicy. Część 1. Opis choroby i charakterystyka patogenów
Authors: Góral Tomasz
Published: December 2023

Fuzarioza kłosów jest chorobą powodowaną przez grzyby z rodzaju Fusarium. Choroba porażą wszystkie zboża uprawiane w Polsce. Największe szkody powoduje w uprawach pszenicy zwyczajnej. Szkodliwość fuzariozy kłosów wynika przede wszystkim z zanieczyszczania ziarna wtórnymi metabolitami Fusarium – mykotoksynami. Mają one szkodliwie działanie dla ludzi i zwierząt w przypadku spożycia żywności lub paszy je zawierającej. W pierwszej części pracy przedstawiono etiologię choroby. Scharakteryzowano gatunki Fusarium powodujące fuzariozę kłosów zbóż wraz w najnowszą systematyką tych gatunków. Opisano najważniejsze mykotoksyny wytwarzane przez Fusarium. Przedstawiono również główne metody ograniczania i zwalczania fuzariozy kłosów.

Authors:   Social Welfare Policy and Practice, Lee Hyoung Ha , Kim Jin-Hee
Published: December 2023

The purpose of this study is to apply latent transition analysis to identify the types of life satisfaction at two points in time, before and after the disability, and to identify the types of transition between time points and factors affecting the transition. As a result of the analysis, first, life satisfaction before the occurrence of disability and life satisfaction in the third year after disability were classified into three potential groups: low-level maintenance, medium-level maintenance, and high-level maintenance. Second, the transition pattern of life satisfaction type for the disabled was different depending on the type of life satisfaction potential profile before disability. Third, depression was identified as an influencing variable that transitions from the ‘low-level maintenance group’ in the third year after the disability in life satisfaction before the occurrence of disability, and in the ‘medium-level maintenance group’ and ‘high-level maintenance groups’, education, marital status, health status, job status, depression, emotional support, degree of disability, and daily life restrictions were identified as transfer factors.
A study on the life experiences of community mental health social workers: Focusing on professional life
Authors:   Social Welfare Policy and Practice, Lee Mikyung
Published: December 2023

This study applies life history research methods to reflect on the individual’s life as a mental health social worker and explores the policies, systems, and historical circumstances of mental health social welfare. This also aims to analyze the interaction between the social environment and the lives of mental health social workers. The research results analyzed based on Mandelbaum’s analysis method show that the first, ‘dimension of life’ is analyzed as “expansion of expertise,” “two sides of health and welfare,” “inclined practice field,” and “survival in the practice field.” Second, ‘turning point’ area is analyzed as “Opportunity and Luck” and “Finding Welfare Identity.” Third, ‘adaptation’ was analyzed as “solidarity and challenge.” Based on the research results, four implications were suggested: Reorganization the medical-centered delivery system into a welfare-centered delivery system; Resolution of the advancement opportunity in Mental Health Welfare Center; Establishment of an education system to strengthen the identity of social workers; Reinforcement solidarity in mental health social welfare practice sites
How Are University Students’ Perceptions and Attitudes Toward Refugees Constructed?
Authors:   Social Welfare Policy and Practice, Kim Seohyun
Published: December 2023

This inquiry aimed to gain a deeper understanding of how their perceptions and attitudes toward refugees formed. The study employed Charmaz’s (2006) constructivist grounded theory, a flexible approach to social reality rooted in a constructivist rather than an objectivist perspective. Participants were selected through continuous comparison and a spiral approach, resulting in 10 male and female university students who met the criteria and voluntarily participated in two to four interview sessions each on the research topic. After analyzing the data in a hermeneutic circle structure, this study identified 60 initial codes and 14 focus codes related to the research topic. These codes were then organized into five theoretical codes to structure the participants’ perceptions and experiences. Specifically, these theoretical codes are as follows: ‘Repulsion toward refugees, which has been taken for granted in Korea,’ ‘Addressing prejudices against refugees in personal ways,’ ‘Engaging in ongoing self-reflection on pro- and anti-refugee attitudes,’ ‘A small solution sought in the slow transformation of refugee inclusion,’ and ‘The future that must change with measures for promoting coexistence with refugees.’ Drawing from these new insights, the study presents discussion points aimed at enhancing social awareness about refugees, reevaluating biases and stereotypes, and expanding opportunities for coexistence with refugees
Getahovit-2. New evidence of an Upper Palaeolithic settlement in northern Armenia
Authors:   National Academy of Science, Republic of Armenia, Kalantaryan Irena , Białowarczuk Marcin , Przeździecki Michał
Published: December 2023

The cave settlement at Getahovit-2 in Armenia has a proven record of human occupation from the Palaeolithic to the Middle Ages, making it the third prehistoric cave site, after Aghitu-3 and Kalavan-1, to be known from this region. The current excavation of an Upper Palaeolithic horizon, discovered in 2014, has yielded a radiocarbon date placing the site within the Last Glacial Maximum, thus filling a gap in the archaeological record between the middle and late Upper Palaeolithic (between 24,000 and 18,000 cal. BP). The short-term occupation by a group of hunters, revealed by the preliminary results, is interpreted with considerable likelihood as a stop during a hunting expedition. Work at the cave site has been resumed under the flag of a newly established Armenian-Polish research cooperation between the Institute of Archaeology and Ethnography of the National Academy of Science of the Republic of Armenia and the Faculty of Archaeology of the University of Warsaw.
