Authors: SUHERMAN CUCU , SUPRIATNA JAJANG , NURAINI ANNE , MUBAROK SYARIFUL
Published: May 2024

The essential role of fertilization in the management of oil palm plantations cannot be overstated, with the understanding that effective strategies must be fine-tuned to accommodate the diversity of soil types present. The nuanced response of oil palm to fertilization under different soil conditions underscores the critical nature of this research. This study investigates the relationship between oil palm farming practices and agro-environmental performance of plantations. This research aims to understand the complex mechanisms influencing plantation productivity. Five agronomic field experiments were carried out on various soil types (Podzol, Inceptisol, Peat) during 2022. These experiments involved various types of soil and used different plant materials in a total land area of 33 hectares. The results of the peat soil trials revealed a positive effect of RP fertilizer on leaf phosphorus (P) content and a visible gradient in potassium (K) content with different doses of KCl. Average plantation yields peaked in 2022, showing the best yields ever recorded. On the contrary, experiments in podzolic soils showed that oil palm responded better to organic fertilizers than to mineral fertilizers in podzolic soils. The inceptisol soil revealed a significant increase in leaf potassium (K) content with KCl dose, confirming the positive effect of fresh oil palm empty fruit bunches (EFB) on potassium levels. In particular, EFB acts as a good K fertilizer, positively influencing the K content but negatively affecting the calcium content (Ca) due to K/Ca antagonism. These findings emphasize the need for diversified agricultural strategies to optimize oil palm cultivation, increase productivity, and reduce dependence on external input.
Unveiling the efficacy of a bacterial antagonist in the management of tomato wilt disease caused by Ralstonia solanacearum
Authors: SOLANKI BUSHRA , KHAN MOHD SAGHIR
Published: May 2024

The long-term application of agrochemicals, including pesticides, in intensive agricultural practices to protect crops from biotic stresses results in the emergence of resistance among phytopathogens and the ineffectiveness of chemical applications. The microbiological strategies, in contrast, minimize the reliance on chemicals and, hence, reduce environmental and human health risks. Bacterial wilt of tomato induced by Ralstonia solanacearum is one of the most destructive diseases worldwide that requires urgent attention to develop a safer and more efficient method to control the phytopathogen. The present work was conducted in the year 2022-2023. In this study, the bacterial wilt was managed by an antagonist bacterium, Pseudomonas fluorescens, exhibiting variable morphological, biochemical, and plant growth-promoting activities. The P. fluorescens inhibited the growth of R. solanacearum in plate assay at different time intervals (0-48 h). The SEM image of R. solanacearum cells cultured with P. fluorescens revealed pores, distortion, and fragmented cell envelope, while the untreated bacterial cells were uniform and smooth. Tomato plants infected with R. solanacearum showed 89% disease incidence compared to uninfected but PGPR-inoculated tomato plants. Application of P. fluorescens reduced disease incidence by 63% compared to R. solanacearum infested plants. Furthermore, plant length enhanced by 21 and 26% significantly following bacterial inoculation after three and four weeks of growth. Conclusively, this study emphasizes the effectiveness of using PGPR as a potent strategy for managing wilt disease in vegetable crops, especially tomato.

Authors: GELDENHUYS GAVIN
Published: May 2024

Helicotylenchus pseudorobustus is one of the tomato fields' most important plant-parasitic nematodes. In this study, the soil was sampled in 2023. The identification and determination of nematodes was made in the Aquaculture Research Unit at the University of Limpopo. During the investigation of this nematode in the Tzaneen region, the properties of soils infected with this nematode, including pH and EC, were investigated. The population of H. pseudorobustus was counted in 100 grams of soil in each season, and soil characteristics were also analysed at the same time. The results in different seasons of the year showed that the range of pH changes during the year of investigation was between 5.2 and 6.6, and the range of EC changes was between 2.9 and 4.3 mS. A comparison of EC and pH changes with population changes showed that the population increased approximately in the months when soil salinity decreased. In addition, soil structure (71.9% sand, 8.0% silt, and 20.1% clay) didn't influence the H. pseudorobustus population. However, the results showed no significant relationship between soil factors and the population dynamic of H. pseudorobustus nematode throughout the year.

Published: May 2024

The expansion of agricultural production and urbanization has led to the depletion of the global forest ecosystem, resulting in land cover changes (LCCs) that pose threats to the land environment. Therefore, it is imperative to identify these LCCs as an essential step toward resolution and mitigation. This study aims to evaluate temporal LCCs in Thai Nguyen province by utilizing GIS and remote sensing techniques (RST) to analyze high-resolution satellite imagery spanning from 2001 to 2023. LCCs were identified using semi-automatic classification plugin (SCP) techniques with Landsat-8 and Sentinel-2 images in ERVI software. The accuracy of the LCC maps was validated through post-classification comparisons, yielding high precision rates ranging from 87% to 96%. The results indicate a significant reduction in forest cover area, declining by 1018 ha from 226,18 ha in 2001 to 207,22 ha in 2023. This decline primarily occurred in urban areas, highlighting the intensification of urbanization processes. Cultivated and bare land experienced a minor decrease and a substantial decrease from 18,631 ha and 105,000 ha to 16,578 ha and 86,82 ha between 2001 and 2010, followed by a slight increase and a significant increase to 5,069 ha and 24,487 ha (1.4% and 6.9%) during the 2010-2023 period. These findings underscore the escalating risk of diminishing forest cover in the study area.

Authors: Manurung Lucy , Kristanti Putriana
Published: May 2024

This study aims to empirically examine the effect of employee competence (KP), organizational commitment (OCM), personal cost (PC), and legal protection (LP) on whistleblowing. Whistleblowing is a system that can be used to report fraud that occurs based on accurate facts and evidence. This study uses primary data in the form of questionnaires distributed online and directly. The samples of this study were principals, vice principals, teachers, and staff of public and private high schools in 5 sub-districts of Yogyakarta City, namely Gondokusuman, Umbulharjo, Gondomanan, Kotagede, and Tegalrejo sub-districts. The data analysis method used is Structural Equation Modeling (SEM). The results of this study obtained 263 respondents and showed that employee competence does not affect whistleblowing, while organizational commitment, personal cost, and legal protection affect whistleblowing. This means that high school employees in the Yogyakarta City neighborhood already have the intention of whistleblowing. It is recommended that officials can improve facilities for employees to carry out whistleblowing if needed by more easily reducing risk (personal cost).

Foucauldian Resistance in Dave Eggers' The Circle
Authors: Raj Paramaguru , Tamilselvi P.
Published: May 2024

The paper titled “Foucauldian Resistance in Dave Eggers' _The Circle_” is analysing the work of dystopian fiction from the perspective of Foucauldian resistance. The paper is structured in a way to depict how power politics is constructed through technical knowledge and how the concept of resistance comes into existence due to digitized dominance. Later, this study depicts how power sustains its position amidst much resistance by nipping the inimical/resistive ideology in the bud itself by manipulating sophisticated technology. Besides, it exposes Foucauldian views that multiple points of resistance aret rarely united together to form a single force. “Resistances are distributed in an irregular fashion: (Kelly, 2009 -106). Modeling on this Foucauldian prediction, resistances at work in _The Circle,_ either inside the company or outside the company are not synchronised together. This inherent weakness of the resistive forces serves as a cause for notwithstanding the power politics of the company. Exploiting this resistive disunity, the company removes all the hurdles working against it easily and holding power perpetually. In addition to this, this paper highlights how the company shatters political power through strategic resistance and exploits the situation in a skillful manner to hold power.
Mumps in Poland in 2021
Authors: Bogusz Joanna , Paradowska-Stankiewicz Iwona
Published: May 2024

INTRODUCTION. Mumps is a contagious viral disease occurring mainly in children, the source of infection being the sick/infected person. Since 2003, vaccination against mumps has been mandatory in Poland, performed according to a two-dose schedule. As part of the Public Health Immunization Program (PSO), the MMR combination vaccine (against measles, mumps and rubella) is used for the entire population of children.
OBJECTIVES. The aim of this study was to evaluate epidemiological indicators of mumps in Poland in 2021 compared to previous years, taking into account the impact of the COVID-19 pandemic.
MATERIAL AND METHODS. The analysis of the epidemiological situation of mumps in Poland in 2021 was based on the interpretation of data from the bulletin , "Infectious diseases and poisonings in Poland in 2021" and , "Immunization in Poland in 2021".
RESULTS. 484 cases of mumps were registered in Poland in 2021. The total incidence was 1.3 per 100,000 residents, which was lower than in 2020. The highest incidence of 1.8 per 100,000 residents was registered in Pomorskie Province, and the lowest incidence of 0.7 in Lower Silesia Province. The highest incidence (6.4/100 thousand) was recorded in children aged 0-4 and 5-9. The incidence rate for men (1.4/100,000) was higher than for women (1.1). In 2021, there were 9 patients hospitalized due to mumps, this was more than in 2020.
CONCLUSIONS. The decrease in the number of cases of mumps in 2021 remained related to the ongoing pandemic - the restrictions introduced during the pandemic period led to a decrease in the number of cases not only of COVID-19, but also of other diseases spread by the droplet route, including mumps. The number of registered cases based on the reports of diagnosing physicians may be underestimating the actual number of cases due to the continued difficult access of patients to primary care physicians.

Authors: Bogusz Joanna , Paradowska-Stankiewicz Iwona
Published: May 2024

INTRODUCTION. Rubella is a viral infectious disease, and humans are the only reservoir of the virus. In 2020, all WHO member countries conducted epidemiological surveillance for rubella, and almost all (99%) had access to rubella testing at laboratories operating under the WHO Global Measles and Rubella Laboratory Network.
OBJECTIVES. The aim of this study was to evaluate epidemiological indicators of rubella in Poland in 2021 compared to previous years, taking into account the impact of the COVID-19 pandemic.
MATERIAL AND METHODS. The assessment of the epidemiological situation was based on a review of data from the bulletin , "Infectious Diseases and Poisons in Poland in 2021" (5), and the assessment of the immunization status of the population was based on data from the bulletin , "Immunization in Poland in 2021" (6). Classification of cases was made based on the definition used in the 2021 surveillance (7). Data from the epidemiological surveillance system "EpiBase" were also used.
RESULTS. In 2021, 50 cases of rubella were registered, 48 fewer than in 2020 (98 cases). There was also a decrease in incidence to 0.13 per 100,000, compared to 0.26 per 100,000 in 2020. The highest incidence, regardless of gender and residential environment, was recorded in the 0-4 age group (1.23 per 100 thousand). No cases of congenital rubella syndrome were reported in 2021.
CONCLUSIONS. In 2021, there was a decrease in the number of rubella cases in Poland, which could be a result of the COVID-19 pandemic and the introduced restrictions. In addition, rubella was registered 99% on the basis of clinical diagnoses, without the required laboratory confirmation, which means that other rash diseases could be registered as rubella

Uloga i (ne)potrebnost za tišinom u štovanju
Authors: Paljević-Kraljik Judita
Published: May 2024

U ovom radu autorica je istražila postoji li i treba li postojati prostor tišine u štovanju Boga u vjerničkom životu, u crkvenom bogoslužju i u dijelu službe u kojemu se slavi Boga pjesmama. Usporedbom dvaju posjećenih bogoslužja dviju zagrebačkih crkava, Evanđeoske pentekostne crkve Stijena spasenja i Kristove Crkve (Kušlanova) te analizom zastupljenosti i uloge tišine, s obzirom na nekorištenje glazbenih instrumenata u Kristovoj Crkvi, zaključeno je da se „prazan” prostor u bogoslužju između pojedinih manjih dijelova bogoslužja upotrebljava na razne načine. Stavljanjem u dijalog intervjue s pastorima spomenutih crkava, Ratkom Medanom i Mislavom Ilićem, i promišljanja teologa i stručnjaka na području kršćanskog bogoštovlja, iznesene su različite definicije tišine, odnosno mira, koji u današnje vrijeme kod mnogih više ne podrazumijeva apsolutnu tišinu. Također je isti problem stavljen u kontekst modernog vremena koje ne poznaje tišinu i kojemu je tišina nelagodna.

Steam Power Plant (PLTU) is a plant that relies on kinetic energy from hot steam to produce electrical energy.  At the Paiton Power Plant, thermal energy is generated from burning a certain amount of coal. The use of coal-fired power plants still dominates most of the world's electricity supply. The optimal operation of electric power systems has grown in importance in recent years due to ever-increasing fuel costs. An electric power system basically consists of power generation units that aim to serve the needs of the load. Total production costs can be minimized by a combination of power loading on existing generating units so that an optimal load or more is obtained. This optimization process is called Economic Dispatch. Economic Dispatch has conducted a lot of research using various optimization methods.  In this study, the optimization method to be used is the Lagrange method. Firefly algorithm and genetic algorithm methods are also used as performance comparisons. The results of this study show that the lagrange method can optimize generation costs with a difference of 243,227,475 $ / hour or 7,043% of the actual cost. While the firefly algorithm gets a difference of 243,227,471 $ / hour or 7.043% of the actual cost. And the genetic algorithm gets a cost difference of 242,119,792 $ / hour or 7,011% of the actual cost.

Published: May 2024

Сучасне суспільство постійно стикається з питаннями гендерної рівності та участі жінок у військовій службі. Традиційні уявлення про ролі статей у суспільстві нерідко не відображають реальні можливості та потреби, що приводить до виникнення стереотипів. Проте сучасний світ постійно змінюється, і з ним змінюються й уявлення про гендерні ролі.
Стаття розглядає тенденції зміни стереотипів у сучасному світі та заходи, спрямовані на забезпечення гендерної рівності у сфері оборони та національної безпеки. Не глядачі на наявність стереотипів, у останні роки спостерігається зростання кількості жінок, які обіймають керівні посади та беруть участь у військових структурах.
ПРОБЛЕМА ІНТЕГРАЦІЇ ТА ДЕЗІНТЕГРАЦІЇ В КОНТЕКСТІ ЗАКОНУ МАТЕРІАЛІСТИЧНОЇ ДІАЛЕКТИКИ

дезінтеграції у філософському розумінні. Акцентовано увагу на єдності та суперечливості процесів інтеграції та дезінтеграції. Подано аналіз понять інтеграції та дезінтеграції, а також розроблено систематизацію їх ознак.
Проблема інтеграції та дезінтеграції представлена в різних наукових галузях, однією з яких є філософія. Аналіз інтеграційно-дезінтеграційних процесів у контексті матеріалістичної діалектики свідчить про їх провідне місце у філософському пізнанні законів природи. Процес інтеграції характеризується поєднанням різнорідних елементів, дезінтеграції – розпадом, руйнуванням цілого на частини. Ці процеси, поряд з єдністю їх функціонування, характеризуються суперечливими висновками.
Протиріччя має універсальний характер, оскільки в будь-якому явищі існує система взаємодіючих протиріч, де одне з них виражає боротьбу внутрішніх сил (внутрішнє протиріччя), а інше характеризує зв’язок із зовнішнім світом (зовнішнє протиріччя).
Встановлено, що у філософії проблема інтеграції та дезінтеграції представлена через близькі поняття матеріалістичної діалектики: протилежність, полярність, протиріччя, антиномія, антагонізм. Аналіз понять закону єдності та боротьби протиріч дозволив з’ясувати сутність інтеграційно-дезінтеграційних процесів і стверджувати, що для них характерна єдність функціонування, в основі якої лежать різні, але внутрішньо пов’язані процеси. протилежних явищ.

Стаття присвячена проблематиці аналізу світового досвіду і психологічних особливостей ефективного використання особливих поліграфологічних методик запитань порівняння – групи поліграфологічних технік, які містять специфічні запитання порівняння (або контрольні запитання) і знаходять широке застосування в криміналістичній практиці. В статті простежуються теоретичні підходи, які лежать в основі розробки і застосування розглядуваної групи поліграфологічних методик, розкривається психологічний аспект розробки і запровадження поліграфологічних методик запитань порівняння, їх відмінність від скринінгових, показані їх позитивні сторони й деякі обмеження. Також охарактеризовано ефективність застосування цієї групи методик, висвітлено методологію і методику їх використання; розкрито можливості застосування основних тестів в нашій державі, представлено дані щодо їх надійності і валідності, а також психологічні вимоги до формулювання основних типів поліграфологічних запитань, які в них використовуються. Показано також перспективи використання зазначених поліграфологічних методик в умовах війни, напрями подальшого застосування в галузях безпекової, спеціальної (оперативної), правоохоронної діяльності і в роботі з персоналом.
МОТИВАЦІЯ УЧІННЯ ЯК ПРЕДИКТОР ВИБОРУ ІНДИВІДУАЛЬНИХ ОСВІТНІХ ТРАЄКТОРІЙ
Authors: Мороз Л.
Published: May 2024

Представлено результати дослідження ролі мотивації учіння під час вибору індивідуальної освітньої траєкторії учнівською молоддю віком 14-16 років залежно від того, у міській чи сільській місцевості вони мешкають. Виявлено психологічні предиктори формування у них уподобань індивідуальних освітніх траєкторій. Встановлено, що орієнтацію на здобуття вищої освіти зумовлює як внутрішня, так і зовнішня види мотивації. Орієнтація на здобуття середньої професійної освіти пов'язана з відсутністю мотивації і відчуженням від учіння. Школяри із сільської місцевості виявили схильність до осілості й більшою мірою орієнтовані на здобуття як середньої професійної, так і вищої освіти.
Cancer Immunotherapy: Challenges and Advancements in CAR T Cell Technology
Authors: Yenchitsomanus Pa-thai
Published: May 2024

Cancer, characterized by uncontrolled cell proliferation, poses a major global health threat, as evident in the 2022 World Health Organization-International Agency for Research on Cancer report, recording 20 million new cases and 9.7 million deaths worldwide. Thailand alone reported 183,000 new cases and 118,000 fatalities, underscoring the need for tailored prevention, early detection, and treatment strategies. Conventional therapies like surgery, radiation, and chemotherapy, while effective in early stages, face limitations in advanced cases, prompting the development of targeted therapies and immunotherapy, notably chimeric antigen receptor (CAR) T cell therapy. CAR T cell therapy employs genetic engineering to create receptors recognizing cancer-specific antigens. Despite successes in hematological malignancies, challenges such as toxicities, relapse, and high costs persist. Ongoing research, led by the Siriraj Center of Research Excellence for Cancer Immunotherapy (SiCORE-CIT), focuses on advancing fourth- and fifth-generation CAR T cell technologies. SiCORE-CIT's fourth-generation CAR T cells exhibit potent anti-tumor activity against various cancers, surpassing second-generation counterparts. Their innovative fifth-generation "Siriraj fifth-generation CAR T cells" secrete anti-PD-L1 scFv, showing potential for diverse cancer applications, highlighting the transformative impact of ongoing research. Successful applications of fifth-generation CAR T cells in B-cell leukemia, lymphoma, and multiple myeloma underscore their transformative potential. This emphasizes the critical role of continuous research in refining therapeutic approaches for both hematologic and solid malignancies. The ongoing exploration and development in this domain have the potential to revolutionize cancer treatment paradigms, significantly contributing to alleviating the global health burden associated with this complex disease.

Estratégias socioespaciais e r(existência) de mulheres assentadas no interior de S. Paulo
Authors: Paula Larissa
Published: May 2024

O espaço rural por muito tempo foi interpretado sob uma perspectiva limitada, que colocava como centro de análise a figura masculina: o agricultor, o pai, o esposo, o filho, o chefe da família, desconsiderando assim, outras personagens que o integram: as mulheres, por exemplo. Aquelas cujos braços sustentam a base da produção com seu trabalho reprodutivo. Cozinham, limpam, educam, criam, costuram, alimentam, plantam, colhem, mas muitas vezes são secundarizadas e relegadas ao esquecimento. Tal situação não foi diferente em análises sobre o espaço urbano. A luta pelo reconhecimento e a valorização do trabalho feminino na sociedade como um todo é um processo iniciado há tempos, que ainda se encontra em devir, e sabemos que as mudanças não alcançam os lugares com a mesma intensidade e ao mesmo tempo. O rural, que é heterogêneo e multifacetado, possui tempos de lentidão. É comum que a mulher rural não tenha consciência do trabalho por ela exercido, já que nas pequenas propriedades e assentamento rurais, há a indissociabilidade entre espaço de produção e de reprodução, tornando complexa a definição precisa do trabalho executado. Por isso a luta destas mulheres começou com uma pauta específica: ter o reconhecimento profissional enquanto agricultoras, pois, a partir disso, conquistariam os direitos que lhes foram historicamente negados. Desde o despertar desta realidade de exclusão, violências, silenciamentos, confrontos, a busca por melhorias das condições de vida e de trabalho têm sido incessantes. A princípio, em meados dos anos 1980, as reivindicações das agricultoras pautavam-se na igualdade de direitos à terra, na política de reforma agrária, acesso à previdência social, no reconhecimento profissional, no direito de se sindicalizar e serem incluídas no bloco de notas fiscais do(a) agricultor(a). Porém, com o decorrer do tempo, o movimento aderiu à novas demandas, passando a lutar por causas mais amplas como acesso ao crédito, às políticas de comercialização e assistência técnica especializada, à alimentação saudável e à agroecologia (BUTTO3 ; LEITE, 2011). Não bastassem lutar por si mesmas, essas mulheres estão à frente de intermediações em prol de suas famílias, das comunidades em que vivem, perseguindo demandas por educação, saúde, habitação, infraestrutura, preservação do meio ambiente, direitos de povos originários, como indígenas e quilombolas, ou famílias atingidas por barragens, enfim, são inúmeras pautas.
