Pollution by palm oil mill effluent (POME) is of great concern in Indonesia. POME pollution of the water can adversely affect aquatic organisms, especially fish. This study aims to analyse the effect of POME on the haematology of tilapia (Oreochromis niloticus), including red blood cells (RBC), white blood cells (WBC), haemoglobin (Hb), Mean Corpuscular Haemoglobin Concentration (MCHC), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Volume (MCV) and haematocrit. A random experimental design was used (CRD) consisting of four treatments and five replications, including a Control (0% POME): Treatment A (10% of LC50-96 hours: 1.565 mg l−1), Treatment B (15% of LC50-96 hours: 2.347 mg l−1) and Treatment C (20% of LC50-96 hours: 3,130 mg l−1). The analysis of blood of fish exposed to POME for 15, 30 and 45 days revealed significant effects (p < 0.05) only on Hb and MCH on day 15 and WBC on day 30. This study indicates that exposure to POME can reduce the WBC value of tilapia recorded on day 30 in treatment C to a level lower than that recorded in other treatments. The Hb value recorded for tilapia exposed to POME on day 15 in treatment C was significantly higher than in the other treatments. Furthermore, POME caused a significant decrease in MCH recorded on day 15, with the lowest value recorded in treatment A. Based on the results of this study, POME can cause a significant decrease in WBC recorded on day 30 and MCH on day 15 and increase in Hb on day 15 in tilapia.

Published: January 2023

In Bosnia and Herzegovina, several illegal waste dumps pose a significant threat to soil and water contamination. The aim of this study was to determine the levels of heavy metal contamination of soils and microbiological contamination of water near investigated landfills. The goal was to identify the harmful effects of illegal landfills on the environment and public health, as well as assessing the potential of contaminants to pollute soil and water resources. Using an Atomic Absorption Spectrometer, the amounts and distribution of four heavy metals (Cd, Co, Pb, and Cr) in soil at four illegal landfills in Central Bosnia were studied. Three water samples collected near the dumpsites studied were tested for microbes. Bacteriological analyses of water included determination of total mesophilic aerobic bacteria, aerobic heterotrophic bacteria, total coliform and fecal coliform bacteria and fecal enterococci. Quantitative results were analyzed using an analysis of variance and Tukey HSD post hoc test. Concentrations of Cd (4.96 mg/kg) and Pb (206.97 mg/kg) recorded in soil at particular sites were above the limits of maximum allowable concentration. Cr and Pb values in soil samples were relatively higher on average than that of Cd and Co. Enrichment factor and pollution load index indicated high concentration of heavy metals in soil, especially Cd. Based on these results, waste from illegal landfills may release considerable amounts of harmful metals and microbes into the environment.
Engaging Students in Chemistry and Physics with an Active Methodology
Authors: Coutinho Isabel Ribau
Published: January 2023

Science, technology, engineering, and mathematics (STEM) play an important role in the global economy through technological innovation, creation, and problem-solving in this century. But it is difficult to capture students’ attention to it, and the loss of students in the STEM field hinders society's development, and Portugal is no exception. The students feel that this field is difficult, they feel disappointed as the academic outcomes are more difficult to obtain in the upper secondary, and they easily give up on this area and/or choose other fields. To mesmerize students in the science area and reinforce their positive emotions a project was elaborated based on flipped classrooms with a laboratory station model and started in September 2021. A study case was designed to perceive the impact of the laboratory station methodology and flipped classrooms on the motivation of upper-secondary science students. Self-response questionnaires were applied before and after an intervention phase where students had flipped classrooms and laboratory stations, experimental classes, during one school year. This research concludes that this teaching methodology allows students to maintain motivation throughout the school year. The teacher´s attitudes regarding school, learning and teaching processes, influence students and can trigger positive emotions concerning overcoming school difficulties and barriers they found during their learning journey. It is essential to disseminate these results, as they can help teachers to face the difficulties of engaging students in the learning process in the science field. As the limitation of this study is the small sample (26 students), this study will be replicated with new students in 10th grade and students who were part of this study will continue to be followed as this methodology will continue to be applied in 11grade.
Multiplexes in India: Building Castles in a Low-income Market of Uneven Geographies
Authors: Gopalkrishnan Sreeram
Published: January 2023

The Indian film industry produces the highest number of movies in the world, in various languages, and casts a large shadow of influence on the socio-cultural landscape of the country. However, in terms of box-office value as a share of the total entertainment pie in India, films are a minor segment in a market with vast potential. The pandemic of 2020 drastically changed the fragile dynamics of the already-struggling film distribution and screening sector. Over the years, the Indian film business has staked its future on a business model forged around the “Mall-Multiplex” complex in a country that is mostly low-income or bottom of the pyramid (BoP). This exploratory article, with the help of existing data on theatre screen seats and high-potential population geographies, endeavours to understand India’s existing film entertainment business and sets out to spot the opportunities available for the low-priced film business as a value proposition.
Regional green transition: Cases of Polish and Russian regions
Authors: Męczyński Michał , Ciesiółka Przemysław
Published: January 2023

The green transition unfolding on a global scale is much less studied at the regional level, although its outcomes and management are strongly place-specific. This article presents a comparative study of green transition strategies in the Silesian Voivodeship (Poland) and the Khanty-Mansiysk Autonomous Okrug (KMAO) – Ugra (Russia), based on a qualitative content analysis of regional legislation and strategies. The regions share common specialisation in fossil fuel mining and have inherited some features of post-socialist economies. Research shows three common features of green transition policies in the studied regions. Firstly, much attention is paid to the dissemination of information about green transition and its benefits. Secondly, research on various green subjects and educational programmes for green market requirements are developed. Thirdly, it is planned for renewables to have a larger proportion in regional energy mixes. By mid-century, both regions are expected to reach climate neutrality, although by using different paths of development. Coal mines are planned to be closed down in the Silesian Voivodeship by 2050, while the KMAO – Ugra will retain its oil-mining specialisation but diversify it with hydrogen production.

Authors: Gao Wei , Yu Zhiqiang , Ma Aijie , Guo Zhangxin
Published: January 2023

The low-velocity impact finite element model of the carbon fiber-reinforced composite grid sandwich structure was established by ABAQUS. Its panels and grid are both carbon fiber-reinforced composite laminates. The constitutive relation of composite laminates is written into the VUMAT user subroutine using the Fortran language. Simulation of intralaminar failure behavior of composite laminates using the three-dimensional Hashin failure criterion. The quadratic stress criterion and the B-K energy criterion were used to simulate the interlaminar failure behavior, and the delamination damage of the composite panel and the interface debonding damage were simulated. The finite element models of four different types of composite grid sandwich structures, including quadrilateral configuration, triangular configuration, mixed configuration, and diamond configuration, were established. The influence of the single grid width and the height of the grid on the impact resistance of each composite grid configuration was studied. Compared with other geometric configurations, triangular grid sandwich structure provides the best energy absorption characteristics, and T-6-10 has the highest fracture absorption energy (15816.46 mJ). The damage propagation law of carbon fiber-reinforced composite grid sandwich structure under impact load is analyzed.
Evaluation of the Compressive Strength of Dry-Stack Concrete Masonry
Authors: Thompson Jason J.
Published: January 2023

The earliest forms of masonry construction were mortarless, utilizing tight-fitting stones bearing directly on one another to enclose space, provide security, or define boundaries. Yet, despite the historical precedent and broad applications of dry-stack masonry, contemporary construction and its supporting research have focused on masonry's mortared counterpart. To bring dry-stack masonry back into mainstream discussion, efforts are under way within the Masonry Society to compile relevant information and publish a new guide focused on the design and construction of dry-stack concrete masonry. As part of those efforts, knowledge gaps have been identified highlighting the need for additional research on or analysis of the performance of dry-stack masonry. One such topic lacking comprehensive data was the establishment of a correlation between the compressive strength of individual masonry units and the corresponding compressive strength of the dry-stack masonry assembly constructed of those units for design application. This research investigation was subsequently undertaken to build on available test data to refine this correlation, particularly at the low end of compressive strengths where data are lacking. Conclusions of this project support a dry-stack assembly compressive strength of 1,500 psi (10.3 MPa) when constructed of units having a minimum compressive strength of 2,000 psi (13.8 MPa).
A Survey of Innovations in Masonry Units Addressing Sustainability
Authors: Subasic Christine A.
Published: January 2023

Sustainability is a topic of great interest to designers and others. With today's increased focus on countering the effects of climate change, building products are subject to closer scrutiny and interest in lower-impact materials has grown. A number of masonry producers and researchers have developed innovative masonry units in response to these interests. Innovative units may include those that incorporate or are made from nontraditional masonry materials as well as units with innovative shapes that provide more efficient designs. Examples include “living” masonry units such as bricks made from the interactions between bacteria and calcium-containing materials, block units that do not require mortar, and units that incorporate solar elements. This paper reviews many of these innovative units as well as the notable advances in the raw materials used in unit production. The unique attributes of each are noted and characterized with regard to the sustainable design issue they address. This paper includes the most current information that is available at the time of writing.
Robotic process automation criteria: Exploratory studies
Authors:   Szkoła Główna Handlowa w Warszawie, Łada Monika
Published: January 2023

This article presents the results of exploratory qualitative research aimed at extending the dominant normative approach to the criteria for qualifying business processes for robotisation. Due to the novelty of the analysed organisational practices, the literature presents mainly general recommendations. Robotic process automation (RPA) is recommended for mass, repetitive information and transaction processes with high stability and a high degree of standardisation. Research on the content of experts' opinions has revealed examples of practices implemented in Polish entities, the characteristics of which are inconsistent with normative recommendations. The studies highlight the wide spectrum and complexity of the criteria, in particular the need to better adapt the criteria to various contingencies, with emphasis put on the specificity of the RPA technology used, alternative methods of process automation, and the stage of advancement of digital transformation in the organisation. Flexibility is indicated as the main distinguishing feature of RPA technology, a feature for which the possibility to quickly process changes (prototyping) and the temporary nature of a process (campaign) are important criteria.
Reversible Inactivation of Ferret Auditory Cortex Impairs Spatial and Nonspatial Hearing
Authors: Town Stephen M. , Poole Katarina C. , Wood Katherine C. , Bizley Jennifer K.
Published: January 2023

A key question in auditory neuroscience is to what extent are brain regions functionally specialized for processing specific sound features, such as location and identity. In auditory cortex, correlations between neural activity and sounds support both the specialization of distinct cortical subfields, and encoding of multiple sound features within individual cortical areas. However, few studies have tested the contribution of auditory cortex to hearing in multiple contexts. Here we determined the role of ferret primary auditory cortex in both spatial and nonspatial hearing by reversibly inactivating the middle ectosylvian gyrus during behavior using cooling (n= 2 females) or optogenetics (n= 1 female). Optogenetic experiments used the mDLx promoter to express Channelrhodopsin-2 in GABAergic interneurons, and we confirmed both viral expression (n= 2 females) and light-driven suppression of spiking activity in auditory cortex, recorded using Neuropixels under anesthesia (n= 465 units from 2 additional untrained female ferrets). Cortical inactivation via cooling or optogenetics impaired vowel discrimination in colocated noise. Ferrets implanted with cooling loops were tested in additional conditions that revealed no deficit when identifying vowels in clean conditions, or when the temporally coincident vowel and noise were spatially separated by 180 degrees. These animals did, however, show impaired sound localization when inactivating the same auditory cortical region implicated in vowel discrimination in noise. Our results demonstrate that, as a brain region showing mixed selectivity for spatial and nonspatial features of sound, primary auditory cortex contributes to multiple forms of hearing.

SIGNIFICANCE STATEMENTNeurons in primary auditory cortex are often sensitive to the location and identity of sounds. Here we inactivated auditory cortex during spatial and nonspatial listening tasks using cooling, or optogenetics. Auditory cortical inactivation impaired multiple behaviors, demonstrating a role in both the analysis of sound location and identity and confirming a functional contribution of mixed selectivity observed in neural activity. Parallel optogenetic experiments in two additional untrained ferrets linked behavior to physiology by demonstrating that expression of Channelrhodopsin-2 permitted rapid light-driven suppression of auditory cortical activity recorded under anesthesia.
Muscarinic Acetylcholine Receptors Modulate HCN Channel Properties in Vestibular Ganglion Neurons
Authors: Bronson Daniel , Kalluri Radha
Published: January 2023

Efferent modulation of vestibular afferent excitability is linked to muscarinic signaling cascades that close low-voltage-gated potassium channels (i.e., KCNQ). Here, we show that muscarinic signaling cascades also depolarize the activation range of hyperpolarization-activated cyclic-nucleotide gated (HCN) channels. We compared the voltage activation range and kinetics of HCN channels and induced firing patterns before and after administering the muscarinic acetylcholine receptor (mAChR) agonist oxotremorine-M (Oxo-M) in dissociated vestibular ganglion neurons (VGNs) from rats of either sex using perforated whole-cell patch-clamp methods. Oxo-M depolarized HCN channels' half-activation voltage (V1/2) and sped up the rate of activation near resting potential twofold. HCN channels in large-diameter and/or transient firing VGN (putative cell bodies of irregular firing neuron from central epithelial zones) had relatively depolarizedV1/2in control solution and were less sensitive to mAChR activation than those found in small-diameter VGN with sustained firing patterns (putatively belonging to regular firing afferents). The impact of mAChR on HCN channels is not a direct consequence of closing KCNQ channels since pretreating the cells with Linopirdine, a KCNQ channel blocker, did not prevent HCN channel depolarization by Oxo-M. Efferent signaling promoted ion channel configurations that were favorable to highly regular spiking in some VGN, but not others. This is consistent with previous observations that low-voltage gated potassium currents in VGN are conducted by mAChR agonist-sensitive and -insensitive channels. Connecting efferent signaling to HCN channels is significant because of the channel's impact on spike-timing regularity and nonchemical transmission between Type I hair cells and vestibular afferents.

SIGNIFICANCE STATEMENTVestibular afferents express a diverse complement of ion channels.In vitrostudies identified low-voltage activated potassium channels and hyperpolarization-activated cyclic-nucleotide gated (HCN) channels as crucial for shaping the timing and sensitivity of afferent responses. Moreover, a network of acetylcholine-releasing efferent neurons controls afferent excitability by closing a subgroup of low-voltage activated potassium channels on the afferent neuron. This work shows that these efferent signaling cascades also enhance the activation of HCN channels by depolarizing their voltage activation range. The size of this effect varies depending on the endogenous properties of the HCN channel and on cell type (as determined by discharge patterns and cell size). Simultaneously controlling two ion-channel groups gives the vestibular efferent system exquisite control over afferent neuron activity.
Texture segmentation method for computer-assisted dermatologic diagnostic system
Authors: Volkova Nataliya P. , Ishchenko Alesya V.
Published: January 2023

The wide spread of dermatological diseases is an important medical and social problem. Doctors note the constant growth of psoriasis among people of all ages. The psoriasis disease symptoms are similar to the symptoms of such diseases as eczema, atopic dermatitis and medicinal disease. Therefore, there is a high probability of an error in the disease diagnosis, which prevents the full treatment and prevention of the disease. Dermatological diagnostic systems are decision-making support systems for dermatologists when establishing a diagnosis and assessing the severity of the disease course. The development of new image processing methods for dermatological diagnostic systems is an important task, which allow to increase the accuracy of the diagnostic decision. In this work, the segmentation method of psoriasis images for systems of medical dermatological diagnostics based on a vector-difference approach to improve the quality of segmentation was developed. The vector-difference approach allows to calculate a certain texture feature of the image as a vector transformation of various texture features by linear algebra methods. Psoriasis disease images can be described by texture (spectral, statistical, spectral-statistical) and color, so it is proposed to take into account textural and color characteristics of images for image segmentation. The color models that are most often used in segmentation methods of psoriasis disease images were analyzed. Based on the analysis, the Hue-Saturation-Intensity color model was chosen.It is proposed to use spectral, statistical and spectral-statistical texture models and color characteristics of image pixels to represent psoriasis disease images. The developed segmentation method includes the following stages: image pre-processing; identification; vector-difference transformation; threshold processing. At the pre-processing stage, homomorphic filtering was applied to psoriasis disease images. The result of the identification stage is a set of features calculated by the textural and color characteristics for image objects. The vector-difference transformation converts the texture image into intensity. Threshold processing is performed with a global threshold. Experimental research of the proposed segmentation method of psoriasis disease images was performed. As a result of the experimental research, it was found that the probability of correct identification of psoriasis disease area on average is 0.97, the probability of a false alarm is about 0.05.

Published: January 2023

A possibility of optimal thermal management of a number of temperature-dependent and heat-laden elements of radio electronicequipment with different power dissipation in an uneven temperature field using a set of thermoelectric cooling devices with mixed electrical connection and fixed geometry of thermocouple branches has been considered.Ratios for determining the relative operating current corresponding to the minimum supply voltage at a given thermal load for different temperature gradients and thermocouple branch geometries are derived. The possibility of selecting a supply voltage for a group of thermoelectric coolers with parallel electric connection using both analytical and graphical methods of solving a system of algebraic equations of first and second orders is shown. The basic parameters, reliability indices and dynamic characteristics of a thermoelectric cooler complex with mixed electrical connection when a group of thermoelectric coolers with series electrical connection operates at maximum cooling capacity and supply voltage variation of a group of coolers with parallel electrical connection are evaluated. Analysis of the research results showed the possibility of selecting the optimum supply voltage for a group of thermoelectric coolers with parallel electric connection in the interrelation of energy, mass-dimensional and dynamic characteristics, taking into account the reliability indicators of the complex as a whole. It is shown that by reducing the supply voltage of a group of thermoelectric coolers with parallelelectric connection included in the complex, the energy, mass-size and dynamic characteristics are improved, and the reliability of the complex with mixed electric connection in an uneven temperature field is increased.

Published: January 2023

This study aims to reveal the process and results of the 1977 Election in West Sumatra. Unlike at the national level taking place under intense competition, the second election during the New Order regime in West Sumatra seemed relatively “quiet.” Golkar comes out as the superior champion. The vote acquisition surpassed the Golkar votes nationally and passed the “Beringin” achievement in the 1971 Election. This study uses a structural history approach. The results show its specific dynamics in West Sumatra, which differed from the national elections. This study uses the historical method of heuristics, criticism, interpretation, and historiography. In the heuristic stage, data were obtained through library research, documentation and archives, field observations, and interviews with selected resource persons based on source criticism. The study results reveal that the 1977 Election in West Sumatra not only resulted in an increase in Golkar’s votes and the defeat of the “opposition party,” especially the PPP, but also signaled the continued consolidation of the New Order regime in Minangkabau. Penelitian ini bertujuan untuk mengungkap proses dan hasil Pemilu 1977 di Sumatera Barat. Berbeda dengan di tingkat nasional yang berlangsung dalam persaingan yang ketat, pemilu kedua pada masa Orde Baru di Sumatera Barat tampak relatif “tenang”. Golkar keluar sebagai juara unggul. Perolehan suara tersebut melampaui perolehan suara Golkar secara nasional dan melewati prestasi “Beringin” pada Pemilu 1971. Penelitian ini menggunakan pendekatan sejarah struktural. Hasil penelitian menunjukkan dinamika spesifik di Sumatera Barat yang berbeda dengan pemilu nasional. Penelitian ini menggunakan metode historis heuristik, kritik, interpretasi, dan historiografi. Pada tahap heuristik, data diperoleh melalui studi pustaka, dokumentasi dan arsip, observasi lapangan, dan wawancara dengan nara sumber terpilih berdasarkan kritik sumber. Hasil kajian mengungkapkan bahwa Pemilu 1977 di Sumatera Barat tidak hanya menghasilkan peningkatan perolehan suara Golkar dan kekalahan “partai oposisi” khususnya PPP, tetapi juga menandakan berlanjutnya konsolidasi rezim Orde Baru di Minangkabau. Cite this article: Israr, Zuhdi, S., Abdurakhman.

Exiled and Convict: Workers and Working System in the Nutmeg Economy in Banda, 1850-1860
Authors: Barjiyah Umi , Margana Sri
Published: January 2023

Banda Islands had a particular landmark in the traffic of world trade history. These islands are recognized as green gold and became one of the main sources of colonial profit. At the peak of the nutmeg trade, the Dutch colonial government built massive perkens (nutmeg plantations). The development of these perkens had scratched a typical history line in Indonesia’s history of economy and colonialism. It created a new economic zone but also laid a dark markdown on the practice of slavery and the workforce on the island. Another consequence was creating a new hybrid social and cultural identity in Banda. This article examines the development of Banda as a new economic zone, the mobilization of workers, and its working system in the nutmeg economy during the colonial period. It argues that the use of exiles and convicts in the nutmeg economy was a colonial strategy to escape to a newly legal ordonnance that abolished the practice of slavery in the perkens. Kepulauan Banda memiliki landmark tertentu dalam lalu lintas sejarah perdagangan dunia. Pulau-pulau ini diakui sebagai emas hijau dan menjadi salah satu sumber utama keuntungan kolonial. Pada puncak perdagangan pala, pemerintah kolonial Belanda membangun perken (perkebunan pala) besar-besaran. Perkembangan perken ini telah menggores garis sejarah yang khas dalam sejarah ekonomi dan kolonialisme Indonesia. Ini menciptakan zona ekonomi baru tetapi juga memberikan penurunan harga gelap pada praktik perbudakan dan tenaga kerja di pulau itu. Konsekuensi lain adalah menciptakan identitas sosial dan budaya hibrida baru di Banda. Artikel ini mengkaji perkembangan Banda sebagai kawasan ekonomi baru, mobilisasi tenaga kerja, dan sistem kerjanya dalam perekonomian pala pada masa kolonial. Ia berpendapat bahwa penggunaan orang buangan dan narapidana dalam ekonomi pala adalah strategi kolonial untuk melarikan diri ke ordonansi hukum baru yang menghapuskan praktik perbudakan di perken. Cite this article: Barjiyah, U., Margana, S.(2022).

This research aims to uncover the taboo of performing wayang puppets in Arcawinangun, Banyumas Regency. The research method uses the historical method. Heuristics are carried out by collecting folklore data processed through external and internal criticism to obtain intellectual historical facts at the local level. This fact is interpreted concerning local wisdom, which produces Banyumas’ intellectual historiography. People of Arcawinangun deem the story of the birth of sacred Parikesit and feel the trauma of the effect of the war of the Bharatas or Bharatayuda. The battle depicts the cruelty and violence causing family members to become victims. To forget it, people create a non-sacred story known as carangan. Bharatayuda passed down sins through murders justified by swear and curses. The war caused the annihilation of the Kauravas, followed by that of the Pandavas. The Pandavas indeed remain intact, but they lost their offspring. Tujuan penelitian ini mengungkap tabu pertunjukan wayang kulit di Arcawinangun kabupaten Banyumas.

Perspectives From Urban WIC-Eligible Caregivers to Improve Produce Access
Authors: Joshi Priyanka , Van Remortel Brittany J. , Cullen Danielle L.
Published: January 2023

OBJECTIVES

The Farmer’s Market Nutrition Program (FMNP) provides fresh, locally grown fruits and vegetables (FV) to eligible participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). However, redemption of FMNP benefits remains low. This qualitative study explores facilitators and barriers to produce access and FMNP redemption for caregivers of WIC-eligible children in Philadelphia during the COVID-19 pandemic.

METHODS

We conducted semistructured phone interviews with caregivers between August and December 2020 to understand experiences with produce access and programming preferences to increase benefit redemption and produce consumption. We used content analysis with constant comparison with code interviews inductively and identified emerging themes through an iterative process.

RESULTS

Participants (n = 30) wanted their children to eat more produce but described barriers to produce access, including limited availability, higher cost, and limited time. The Supplemental Nutrition Assistance Program and WIC benefits improved the ability to purchase produce, but difficulties with electronic benefit transfer and pandemic-related office closures limited use of WIC benefits. Similarly, lack of convenient market locations and hours prohibited use of FMNP benefits. Caregivers described that an ideal food program would be delivery based, low cost, offer a variety of FV, and provide recipes and educational activities.

CONCLUSIONS

WIC-eligible caregivers want their children to eat more produce; however, they face multiple barriers in redeeming their benefits to access fresh produce. Delivery-based, low-cost produce programs may lead to increased produce access as well as benefit use. Future study is needed on feasibility and acceptability of produce delivery options among WIC-eligible families.
Comentários hegelianos à Relectio de Matrimonio, de Francisco de Vitória
Authors: Marques Rogério Tadeu Mesquita
Published: January 2023

Este artigo busca fazer um paralelo da Relectio De Matrimonio, de Francisco de Vitória, com a visão sobre o matrimônio desenvolvida na obra Filosofia do Direito, de Hegel. Apesar dos pressupostos serem diferentes, o escolástico tomista, jusnaturalista, concorda em vários aspectos com o idealista alemão contemporâneo, seja na monogamia, na proibição de consanguinidade, da essencialidade da liberdade das partes e até das circunstâncias da dissolução do vínculo. Ainda que ambos fossem teóricos e não juristas no sentido prático, suas reflexões têm também em comum uma unidade entre teoria e prática que talvez seja a verdadeira chave para decifrar o porquê de raízes tão distintas chegarem a muitas conclusões idênticas em períodos diferentes do pensamento.
Highly Efficient Removal of Methylene Blue Dye from Wastewater Using CaO-MnFe2O4 Nanoparticles Prepared with Teak Leaf Extract
Authors: Rodiah Siti , Ramadhani Ericha
Published: January 2023

This research aimed to synthesize a semiconductor photocatalyst CaO-MnFe2O4 nanoparticles using teak (Tectona grandis) leaf extract to degrade methylene blue in wastewater. Nanocatalysts were prepared through the precipitation method, while anthocyanins in extract acted as a reducing and stabilizing agent in this process. The presence of spinel ferrite (Fe-O), and manganese ferrite were indicated by using a Fourier transform infrared (FTIR) spectrometer that showed vibrational peaks at areas 538 cm-1 and 872 cm-1, respectively. The crystalline phase of CaO-MnFe2O4 was confirmed using an X-Ray diffractometer (XRD) that appeared peaks at 2θ: 18º; 29º; 34º; 47º; 52º, while peaks at 2θ: 32º; 37º and 54º indicated CaO. Through the Debye-Scherrer equation, the CaO-MnFe2O4 nanoparticles had an average crystal size of 8.6 nm. The morphology of CaO-MnFe2O4 nanoparticles was clearly visible in the Scanning electron microscope (SEM) results in the form of fibrous clumps. The CaO-MnFe2O4 nanoparticles could degrade methylene blue with a degradation percentage of 86% over 240 min.

This article attempts to describe the biography of the prolific kiai writer and translator of the kitab Pegon, Kiai Asrori Ahmad who lived Wonosari, Magelang, Central Java in the twentieth century. The kiai, who was born in 1923, is widely known as a writer of numerous written books of Pegon, both in the form of translations and original ones. His work remarkably scattered in various Islamic disciplines, such as fiqh (Islamic jurisprudence), tawhid (monotheism), hadith, akhlaq-tasawwuf and sirah (history). In order to describe the biography of kiai Asrori comprehensively, this article uses the historical-codicological method by basing it on primary sources, such as interviews with kiai Asrori Ahmad's family and examining his works, as well as other supporting sources. Based on historical analysis. The result revealed that kiai Asrori Ahmad is a product of Islamic boarding school education who had the expertise of kitab kuning (yellow book). This special expertise was later developed by Kiai Asrori by improving it in within the tradition of the pesantren library, the book of pegon, under the guidance of Kiai Bisri Mustofa Rembang, one of the foremost preaching kiai and author of the twentieth century book of Pegon. Under the direction of his teacher who later became brother-in-law, Kiai Bisri Mustof, kiai Asrori eventually transformed into one among prolific writers of pegon book in the twentieth century. The record demonstrated approximately 30 titles spread out in 50 books that have been born from the patience and perseverance of Kiai Asrori Ahmad. All of his works were hatched from three important motivations: religious motivation, educational motivation and economic motivation.

Published: January 2023

This study aims to analyze the communication strategy of the agricultural insurance program in the South Kalimantan region to create superior and independent farmers. This communication strategy can contribute to existing development programs in the South Kalimantan region. This research used qualitative methods with SWOT and TOWS analysis techniques. Data collection techniques were open interviews, focus group discussions (FGD), and field observations (research locations and district level). The results of the study showed that agricultural insurance in the South Kalimantan region had obstacles that occurred in the field. Many farmers did not understand and were not interested in participating in this rice farming insurance. First, the analysis of the agricultural insurance communication strategy in the SWOT analysis in the South Kalimantan region was to increase the quality capacity of government human resources in the field by providing socialization technical training and involving opinion leaders, groups, and village governments in disseminating information. Second, the communication strategy in the TOWS analysis was to optimize the existing social capital in the community, form information centres at the village level, add variety and diversity in the methods of conveying information by extension workers and Jasindo officers and provide a variety of media sources of information, especially social media, and internet. The agricultural insurance communication strategy is essential to policymakers in implementing development programs.
Health benefits of co-supplementing mealworm protein hydrolysate and cranberry fruit extract

Published: January 2023

The demand for valuable protein sources is increasing. The mealworm has been highlighted as a good source of protein. Nevertheless, beneficial effects of mealworm such as the antioxidative and/or anti-inflammatory effects are rarely studied. It is well-known that cranberry fruit has a strong antioxidant effect. The biologically active compounds in mealworm and cranberry could boost the antioxidative and/or anti-inflammatory effects. The current study investigated the interactive effects of mealworm protein hydrolysate (MWPH) and cranberry fruit extract (CFE) in mammals. We evaluated growth performance, relative organ weight, immune responses, antioxidant enzyme activities, blood properties, and fecal microflora. A 2 × 2 factorial experimental design was used. The co-supplementation of MWPH and CFE improved serum glutathione peroxidase. MWPH affected a lower serum IL-1β and fecal Clostridium density. The co-supplementation appeared more effective in terms of good health and potentially the prevention of disease.

Plug-Assisted Retrograde Transvenous Obliteration for the Treatment of Gastric Varix with Both Gastrorenal and Gastrocaval Shunts: A Case Report
Authors: Shim Jongjoon , Lee Jae Myeong
Published: January 2023

Gastric variceal bleeding has a poor prognosis and a high mortality rate. Balloon-occluded retrograde transvenous obliteration has traditionally been applied in the treatment of gastric varix. Recently, plug-assisted retrograde transvenous obliteration (PARTO) has been widely and popularly applied for the treatment of gastric varix. There have been no reports of cases in which PARTO was performed in patients with both gastrorenal shunt and gastrocaval shunt. We report a case in which PARTO was performed on a patient with gastric varix who had both a gastrorenal shunt and a gastrocaval shunt.
Polypoid Endometriosis, a Benign Tumor with Perplexing Radiologic Features: A Case Report
Authors: Hong Jeong-A , Han Hyo Sang , Jeon Dongsoo
Published: January 2023

Polypoid endometriosis is a rare form of endometriosis. It is a benign variant but its radiologic findings trick clinicians into concern about the tumor being malignant. A 42-year-old patient with a history of dysmenorrhea and adenomyosis presented a 60 mm-sized mass in the Douglas pouch with irregular echogenicity. The patient went under the first surgery for tumor removal, and its histopathologic diagnosis was endometriosis. We started daily dienogest medication to suppress tumor recurrence, but after 10 months we decided to stop the medication due to the side effects. Four months after the cessation, a new tumor recurred and after few months of observation, we performed the second surgery of tumor removal and total hysterectomy because of adenomyosis. The tumor was located in the retroperitoneal space in the Douglas pouch with severe adhesions. After the second surgery, the tumor marker Cancer antigen-125 level was normalized and the histopathologic result was endometriosis, which we concluded as polypoid endometriosis.
An Inguinal Endometriosis without Any Other Pelvic Endometriosis Mimicking Direct Inguinal Hernia: A Case Report
Authors: Jeon Dongsoo , Hong Jeong-A
Published: January 2023

Inguinal endometriosis is a rare disease. Patients with inguinal endometriosis usually exhibit cyclic inguinal pain with a cyclic change in the size of the inguinal mass. It is more often found on the right side and commonly accompanies concomitant endometriosis lesions on pelvic organs or peritoneum. We report a case of inguinal endometriosis without any of the usual characteristics. A 48-year-old with non-severe dysmenorrhea and pelvic pain presented a left inguinal mass, palpable only when standing. Under the impression of direct inguinal hernia, laparoscopic herniorrhaphy was performed. Intraoperative laparoscopic findings revealed no other endometriosis lesion on the pelvic organ or in the abdominal cavity, and the histopathologic report confirmed it was endometriosis. Thorough inspection and excision of endometriosis lesions in the pelvic cavity are crucial for treatment. Therefore, an appropriate surgical plan following accurate preoperative diagnosis is important. If the intraoperative evaluation of endometriosis was not enough, postoperative gynecologic assessment is strongly recommended.
