Published: December 2024

The Piperaceae family is one of the aromatic plants that have a distinctive odor and is known to have tremendous benefits in human life.  Piperaceae is used as raw material for medicines, spices, antibacterial, antiviral, and insecticides. Research on the composition of volatile chemical compounds in Piperaceae members is still limited. This study aims to extract volatile chemical compounds in the Piperaceae family and classify Piperaceae members based on their volatile compounds. The type of research is laboratory research. The research samples were leaves of ten species of Piperaceae members, namely Piper cubeba, P. nigrum, P. betle, P. ornatum, P. retrofractum, P. sarmentosum, Peperomia pellucida, Peperomia scandens, Peperomia caperata, and Peperomia maculosa. The research instrument was an observation sheet of SPME-GCMS analysis results. Data in the form of metabo-analysis was obtained from laboratory analysis using SPME-GCMS by producing a comprehensive volatile compound profile of the Piperaceae family and revealing differences between species. The results of SPME-GCMS analysis on the Piperaceae family obtained 197 identified volatile chemical compounds. The largest group of chemical compounds in 10 species of the family consists of sesquiterpene (16.2%), monoterpene (11.7%), sesquiterpenoid (7.1%), alcohol (6.1%), aldehyde (4.6%), terpene (4.1%), terpenoid (4.1%), alkene (3%), fatty acid (2.5%), ketone (2.5%), phenol (2.5%), alkane (2%) and other groups less than 2%.  Characteristics of typical compounds in the genus Peperomia amounted to 10, namely Alpha-pinene, (-)-; Camphene; 2-beta-pinene; l-Limonene; Nonanal; (-)-.beta.-Elemene; alpha.-Copaene; Germacrene D; cis-caryophyllene; Bicycloelemene. In the genus Piper, the variation in the character of volatile chemical compounds is very large, typical characteristics possessed by 6 Piper species are alpha-pinene, (-)-; alpha.-Copaene; alpha.-Humulene; (-)-beta.-Elemene; and trans-Caryophyllene. The study concluded that 197 volatile compounds from 10 Piperaceae species had been identified. The results of this study can be recommended that the Piperaceae family can be optimized for public health.

Published: December 2024

This study explores the socio-cultural dynamics of Javanese coastal communities, emphasizing the existence of their indigenous traditional beliefs: Javanism (Kejawen) with its unique spirituality and Abangan, which practically reflects Islam in a syncretic form blending Javanese culture and Sufism. The research focuses on six regions: Subang, Cirebon, Pekalongan, Rembang, Tuban, and Pasuruan. Using Spradley’s domain, it examines the spiritual frameworks and practices of Kejawen and Abangan, including distinctive traditions such as mysticism and cultural titles. Participatory observations reveal that Kejawen and Abangan communities continue to preserve their beliefs, actively practising them while shaping a communal identity that strengthens social bonds. Ironically, some deviant practices, such as shamanism, charms for wealth, and occultism, are often associated with these groups. The findings also highlight the critical role of religious moderation in safeguarding traditional practices, addressing misuse of beliefs, and promoting harmony. This study offers valuable insights into the resilience of Javanese culture amidst the dynamics of contemporary society.
Influence of Powder Feed Density on Mechanical Properties and Microstructure in L-DED Additive Manufactured STS316L
Authors: Jung Jaeho , Jo Min Cheol , Lee Keunho , Park Leeju
Published: December 2024

Laser Directed Energy Deposition (L-DED) is a notable additive manufacturing method in which metal powder is sprayed through a nozzle and then consolidated layer by layer using a laser. Unlike other additive manufacturing processes, DED has fewer constraints on the size of the fabricated parts, making it advantageous for the production of large-scale components. However, the use of DED in additive manufacturing requires careful optimization of various process parameters, including laser power, powder feed rate, nozzle scanning speed, and deposition path, as these parameters significantly influence the geometry and properties of the fabricated parts. Recent studies have extensively investigated the microstructure and properties of parts fabricated via DED at different energy densities, but research on variables related to powder feed is still lacking. In this study, using Powder Line-Density (PLD) as a parameter, changes in bead geometry, microstructure and mechanical property followed by variation in powder feed density while conducting DED additive manufacturing with STS316L were observed. Controlled by powder feed rate and scanning speed, the Powder Line-Density was utilized for 1-line deposition with STS316L alloy powder, enabling the observation of bead geometry and melt-pool shape during the deposition process. Additionally, square-shaped specimens were manufactured via DED with controlled Powder LineDensity to observe the resulting microstructure and mechanical properties. It was observed that, even for the same energy density, specimens exhibited distinct grain morphologies, microstructure, and mechanical properties depending on the Powder Line-Density, with a particularly significant change in anisotropy. This highlights the importance of powder feed density as a key variable alongside energy density to optimize DED additive manufacturing processes. The findings of this study are expected to contribute to the control of anisotropy and strength of fabricated components in metal additive manufacturing processes by the regulation of powder feed density.
Optimization of Mechanical Machining for Heat-Resistance Ta-W Alloy by Using Orthogonal Cutting Method
Authors: Kim Kyu-Sik , Kim Sinwon , Mun Chang Hyeon , Park Jung Hyo , Kim Donghoon , Yang Seongho , Park Hyung Wook
Published: December 2024

Tantalum and tantalum alloys, which have superior thermal properties, including a high melting temperature, low specific heat, low thermal conductivity, and high density, are promising candidates for highperformance parts exposed to high temperatures and hazardous environments in aerospace, defense, and other industries. However, those alloys are hard to cut and mechanically machine, and the poor machinability of tantalum alloys has precluded their wide use. This study investigates mechanisms for cutting Ta-10%W alloys using orthogonal cutting methods for precision part manufacturing. During orthogonal cutting processes, the cutting forces are increased dramatically because of the surface folding phenomenon of Ta-W alloys. As a result of experiments and simulation calculations, the tool’s rake angle and depth of cut are critical parameters for controlling the cutting shear angle, which makes a significant difference in chip thicknesses and surface folding phenomenon. Based on the results, about 12 degrees of cutting shear angle is suitable for the mechanical machining of a Ta-W alloy. Additionally, cutting speed may be one of the critical parameters to consider for changing the mechanical responses of Ta-W alloys. With this perspective, the mechanical properties of Ta-W alloys at high strain rates seem to be an important factor in orthogonal cutting. Based on these results, the cutting mechanisms and optimal cutting parameters for Ta-W alloys are discussed.
Microstructure and Tensile Behaviors of Laser-Arc Hybrid Welds Comparing to Submerged Arc Welds of High-Manganese Steel for Cryogenic Applications
Authors: Choi Myeonghwan , Lee Kwang-Hyeon , Cho Dae-Won , Kang Namhyun
Published: December 2024

The weldability and the relationship between microstructure and tensile properties at 298 and 110 K produced by laser-arc hybrid welding (LAHW) in high-Mn steel welds were thoroughly investigated. In the laser zone of LAHWs using filler wire, more Mn vaporization in the laser zone was observed than at the arc zone of LAHWs. The arc zone showed a decrease in Mn content of ~0.6 wt%, while the laser zone showed a decrease of ~0.9 wt%. The arc and laser zones of the LAHWs showed stacking fault energies (SFEs) of 17.8 and 17.3 mJ/m², respectively. The tensile deformation of LAHWs at 298 K was conducted with a deformation twins mode, while it was shifted to deformation twins + ε-martensite transformation at 110 K. The yield strength was slightly higher in the laser zone, which had a finer grain size compared to the arc zone. The formation of ε-martensite with deformation twins preceded necking during tensile testing, therefore increasing the yield strength at 110 K. In terms of performance, the LAHW process demonstrated a 25% increase in productivity compared to the conventional submerged arc welding (SAW) process, with a yield strength exceeding 400 MPa, comparable to that of SAW. These findings indicate that LAHW is a highly effective welding method for high-Mn steels, particularly in cryogenic applications.

Published: December 2024

Plasma thermal spray coating method was applied to prepare a high performance neutron shielding layer for various applications such as nuclear spent fuel transportation and storage containers and experimental research reactors. In this study, layers with various compositions of a gadolinium oxide neutron absorber and a nickel alloy binder on a 304 stainless steels substrate were deposited by the plasma thermal spraying method, and their performance including the neutron shielding ability and the corrosion behavior was evaluated to develop a high performance thermal neutron shield coating layer. In the neutron shielding test results, layers with more than a 450 m thick coating with a 1:3 ratio of gadolinium oxide and nickel alloy binder provided 100% thermal neutron shielding against a neutron beam with energy of 48.4 meV and a wavelength of 0.13 nm. Electrochemical corrosion tests showed that the corrosion potential and corrosion rate of the thermal spray coated layers in the artificial sea water were lower than -0.833 VSHE and slower than 7.12×10-5A/cm2, respectively. Both the neutron shielding and the corrosion resistance tests results suggest that neutron shielding layers with thickness exceeding 450 m formed by the plasma thermal spraying method can be effectively applied as a thermal neutron shielding material for spent fuel transportation and storage containers and experimental nuclear reactors.

Published: December 2024

Abstract
This study compares the implementation of asymmetric decentralization in Indonesia and its effect on poverty alleviation. The method used in this study is a comparative case study (CCS), where the researchers compare two regions that implement an asymmetrical decentralization system: the Special Region of Yogyakarta and Papua, with different outcomes. From the data collected in the field, researchers found various challenges in implementing asymmetric decentralization, especially in poverty alleviation efforts. In the case of Papua, there are several challenges, including the effective allocation of budget and the strengthening of human resources. In contrast, in Yogyakarta, the focus of implementing legal asymmetry is enhancing culture and governance. Hence, poverty alleviation initiatives must also consider these central aspects. This research can contribute to developing development studies and public policies on poverty alleviation. The researcher provides an in-depth analysis of two exceptional cases applying asymmetrical decentralization in their activities.

Authors: Siradj Agung Muhammad , Sudarmono Sudarmono
Published: December 2024

Abstract
 
This research aims to understand how collaborative governance between the Buton Regency government and other stakeholders related to stunting issues can collaborate and contribute to reducing stunting rates, particularly in the Bajau ethnic community living in the Buton region. Due to their long-standing isolation above the sea, the Bajo/Bajau community has a lower level of welfare compared to other ethnic communities in Buton. Through a descriptive qualitative approach, the researcher found that although collaboration has been effective at the government level, there are still several obstacles, such as suboptimal private sector involvement and low health awareness among the Bajau community. This research can contribute to an approach to governance, especially at the regional level, that prioritizes aspects of collaboration and does not leave the socio-cultural aspects in the community.
Keywords: stunting, collaborative approach, Bajau community; local government.

Resistance of Regional Governments in the Implementation of E-Government
Authors: Gita Khuzaimah Maulida
Published: December 2024

According to the UN E-Government Survey, Indonesia achieved a High E-Government Development Index (EDGI) rating with a score of 0.6612 and ranked 88th out of 193 countries. However, monitoring and evaluation results conducted by the Ministry of Administrative and Bureaucratic Reform presented a different outcome. The implementation of e-government at the regional government level shows that 20.63% still received a poor rating, and 50% received a fair rating. Meanwhile, in central institutions, only 7% received a poor rating, while 54% received a good rating and 13% received a very good rating. Based on this data, the implementation of e-government is not consistent or well distributed, and it is suspected that there is resistance to the implementation of e-government in some regional governments. This article uses a literature study approach by reviewing various relevant sources, including journals, books, scientific reports, and other documents. The results of this study indicate that the resistance at the regional government level is caused by several factors, namely mindset, human resource capacity, regulations, infrastructure, and finance.

Published: December 2024

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type. We performed a systematic review and an individual patient data meta-analysis (IPDMA) in accordance with PRISMA guidelines, focusing on surgical interventions for ES and reporting seizure outcomes using the Engel or ILAE scales. Twenty-six studies encompassing 358 ES patients undergoing resection/callosotomy were included. Participants undergoing other approaches (e.g., multiple subpial transections) or multimodality approaches were excluded from analysis. The median age at spasm onset was 6 months (IQR = 3.0–15.6), with a median age at surgery of 37 months (IQR = 17.2–76.8). Most patients (74.1%) exhibited additional seizure types. A total of 136 patients (35.8%) underwent corpus callosotomy (CC), of whom 125 (91.9%) had a complete callosotomy, while 11 (8.1%) had a partial callosotomy. Resective surgery was performed on 222 patients (58.4%). Among those who underwent resection, 109 (49.1%) had both lesional MRI findings and lateralized EEG abnormalities. Overall, 201 patients (56.1%) remained spasm-free at a median postoperative follow-up of 36 months (interquartile range, IQR = 21–60), including 52 (38.2%) from the callosotomy group and 149 (67.1%) from the resective surgery group. In the resective surgery cohort, patients with MRI-confirmed lesions (p = 0.026; HR = 0.53, 95% CI = 0.31–0.93) and those who underwent hemispherectomy (p = 0.026, HR = 0.46, 95% CI = 0.23–0.91) had better seizure outcomes. Only a minority (24.4%) underwent invasive EEG monitoring prior to ES surgery. Surgical treatment of ES proves effective, with two thirds of patients undergoing resective surgery and a third undergoing CC becoming spasm free. Post-operative developmental improvement was observed in 44 participants (65.7% of those with available data). The presence of lesional MRI and more extensive resection/disconnection (e.g., hemispherectomy) emerged as significant prognostic factors for spasm freedom and can inform clinical decision-making.

A partir das leituras realizadas compreendemos o quanto as instituições de ensino devem acompanhar as dinâmicas das áreas de tecnologia enquanto ferramenta de gestão, sabendo ajustá-las ao contexto de cada sociedade, em especial no que se refere a seu público, o aluno. Nesse sentido, concluímos pela necessidade de repensar as ações de Educação a Distância nas instituições de ensino presencial Moçambicanas, de maneira a que ela se constitua, de fato, em instrumento de democratização do acesso à educação de qualidade no país.
Discursos contemporáneos sobre reforma educativa en la Argentina y Sudáfrica: un estudio comparado
Authors: Wolhuter Charl , Gorostiaga Jorge Manuel , Pastore Pablo German
Published: December 2024

Este artículo compara los procesos de articulación de los discursos sobre reforma educativa en dos naciones ubicadas en el Sur Global, la Argentina y Sudáfrica, en las últimas tres décadas, desde la perspectiva de la Educación Comparada e Internacional. Siguiendo trabajos antecedentes, se toman como referencia las principales narrativas que articulan los discursos sobre reforma educativa en este campo académico y en eldiscurso público, aunque el artículo pretende mostrar que los procesos ocurridos en cada caso nacional presentan selecciones y reformulaciones de estas grandes narrativas según sus propias dinámicas sociohistóricas. Por esta razón, incluimos un breve racconto social e histórico de ambos países —con énfasis en sus realidades educativas— lo que sirve de fondo para una exploración y discusión de los discursos sobre reforma educativa. El procedimiento metodológico seguido en esta indagación consistió, primero, en una revisión bibliográfica, dando cuenta de textos académicos y documentos de política claves en el período seleccionado en ambos países. En segundo lugar, la comparación entre la Argentina y Sudáfrica fue realizada siguiendo el enfoque desarrollado por Schriewer (2019), esto es, buscando convergencias y divergencias  entre los casos bajo el supuesto de una causalidad compleja y del reduccionismo de las “grandes teorías” universalizantes.
Investigación educativa para tiempos crepusculares: narrativas como materialidades, autorizaciones y cabildeos en el campo pedagógico
Authors: Yedaide María Marta
Published: December 2024

Este artículo comparte algunas inquietudes gestadas y nutridas a propósito de una estancia posdoctoral que incluyó ateneos —algunos más informales y espontáneos y otros preparados, filmados, y posteriormente ofrecidos para su refractación y análisis— así como el registro atento al acompañamiento de una tesis de doctorado construida en clave autobiográfica narrativa. Nos convocaba la investigación educativa —particularmente las experiencias que en favor de lo pedagógico político vamos propiciando en ciertos enclaves universitarios, en rebeldía con un conjunto de instituidos que colaboran, entendemos, con ciertas indignidades y dolores contemporáneos—. El texto compone una memoria de la estancia y luego utiliza tres historias a partir de las cuales se despliegan ciertas tesis construidas al calor y color de la experiencia posdoctoral. Metodológicamente, entonces, implica el análisis de materiales compuestos en una etnografía previa de larga duración, por un lado, así como el abordaje de relatos de una experiencia y de narrativas de sucesos sociales que asemejan instancias de etnografía urbana. A partir de estos movimientos se entraman aportes teóricos y perspectivas ontoepistémicas en pos de robustecer un tipo de investigación narrativa estimulante, capaz de materializar transformaciones pedagógicas en el amplio dominio de la vida común.
Violencia escolar: dilemas conceptuales y epistemológicos. Una revisión crítica en catálogos iberoamericanos
Authors: Patierno Nicolas
Published: December 2024

El presente artículo se propone llevar a cabo una revisión conceptual de la violencia escolar con el objetivo de sistematizar y analizar la multiplicidad de definiciones y corrientes teóricas que influyen sobre la objetivación de la problemática. Para ello se optó por un trabajo documental orientado a identificar los principales enfoques teóricos en la bibliografía especializada. En este marco, se analizaron trece estudios disponibles en tres catálogos de amplia circulación en Latinoamérica: SciELO, Redalyc y Google Académico. Como resultado, se propone una serie de consideraciones epistemológicas para la realización de investigaciones orientadas en esta temática. El fin último de estos aportes es reforzar el estudio científico de la violencia en ámbitos escolares para desarrollar propuestas educativas que ofrezcan respuestas a una problemática confusa y controversial.
Memoria y transmisión entre las generaciones
Authors: Silveyra Malena
Published: December 2024

La búsqueda por “mantener viva” la memoria de los crímenes de la dictadura ha tenido como objetivo central garantizar el emblemático “Nunca Más”. Sin embargo, a pesar de las múltiples iniciativas y políticas públicas en ese sentido y de haber sido referencia internacional en la materia, el crecimiento y triunfo electoral de expresiones que reivindican la represión nos obligan a repensar los sentidos sobre la memoria, la transmisión y lo realizado hasta el momento. En este artículo nos proponemos poner en discusión la construcción de la memoria, sobre qué necesitamos recordar y para qué, y la transmisión generacional de la misma.
التحليل المكاني لمواقع المساجد فـي دولة الكويـت باستخدام نظم المعلومات الجغرافية
Authors: محمد غانم المطر
Published: December 2024

الأهداف: ركزت الدراسة على فهم طبيعة التوزيع الجغرافي للمساجد بالمنطقة الحضرية في دولة الكويت، وتَقييم الخدمات الدينية من منظور جغرافي. المنهج: اعتمدت الدراسة على المنهج الإحصائي لدراسة التوزيع الجغرافي للمساجد، ولتعرّف مدى كفايتها وتوافقها مع التوزيع السكاني في منطقة الدراسة. النتائج: كشفت النتائج أن التوزيع الجغرافي للمساجد في دولة الكويت غير منتظم؛ فهناك مناطق تزداد فيها أعداد المساجد عن الحاجة الفِعلية، وهناك مناطق يوجد بها عجز وتحتاج إلى إنشاء مساجد جديدة، وهذا ناتجٌ من عدم وجود توازن بين أعداد المساجد وأعداد السكان وتوزيعهم فيها. وقد تبين من الدراسة أن هناك بعض المناطق ذات كثافة عالية في عدد المساجد، في حين كانت المناطق المجاورة لها ذات كثافة منخفضة عنها، ومنها مناطق: شرق، القبلة، أم الهيمان، صباح السالم. أما منطقتا: الشدادية، وأمغرة فهما من المناطق ذات الكثافة المنخفضة في عدد المساجد، وتحيط بهما مناطق مرتفعة عنهما في كثافة المساجد. كما تبين من الدراسة وجود علاقة طردية ضعيفة بين أعداد السكان وأعداد المساجد في بعض المناطق؛ أي: إنه كلما زاد عدد السكان في المناطق زاد عدد المساجد فيها بنسبة غير كافية. الخاتمة: تُسهم النتائج التي تم التوصل إليها في الارتقاء بمستوى الخدمات الدينية في منطقة الدراسة، إذا تم وضعها في الأولويات التخطيطية لمناطق الكويت، وقد تُسهم نتائج هذه الدراسة وتُلهِم صانعي القرار في تحسين التوزيع الجغرافي الأمثل للمساجد في دولة الكويت.
Epstein-Barr Virus Encephalitis as a Cause of Status Epilepticus – A Rare Encounter

Epstein-Barr virus (EBV) is associated with infectious mononucleosis and is known to cause various neurological complications, albeit rarely. EBV encephalitis is a rare manifestation, and even rarer is its presentation as status epilepticus. To date, fewer than ten cases of EBV encephalitis presenting as status epilepticus have been reported globally. We report a case of an 18-year-old girl who presented with fever followed by seizures. She went into status epilepticus the next day. Cerebrospinal fluid (CSF) analysis showed lymphocytic predominance. Brain imaging showed bilateral symmetric hyperintense lesions in the caudate and the putamen. EBV IgG and IgM were found to be positive. The patient was treated with ganciclovir and anti-epileptics and she improved gradually. Our case emphasizes the importance of considering EBV encephalitis as a potential cause of status epilepticus, even in individuals without immunodeficiency. Recognizing atypical presentations and appropriate diagnostic investigations can facilitate early diagnosis and treatment initiation.

Cytoskeletal dynamics, the interplay of actin, microtubules, and septins, is a highly coordinated and tightly regulated process. Defects in the proteins involved can result in a wide range of cellular consequences. Hearing loss is the most common sensory defect and exhibits extraordinary genetic and phenotypic heterogeneity. Currently, there are more than 170 genes casually linked to non-syndromic hearing loss (NSHL), of which more than 60 are associated with autosomal dominant inheritance. Here, we add to this growing number by implicating MACF1 (OMIM # 608271), as a novel candidate gene for autosomal dominant non-syndromic hearing loss (ADNSHL). MACF1’s cytoskeleton integrator function and hair cell expression pattern lead one to believe that it is a necessary protein for hair cells. Many protein domains in MACF1 allow for dynamic interaction with the cytoskeleton. A large Iranian family segregating progressive ADNSHL was recruited for this study. The proband had bilateral mild-moderate sensorineural hearing loss and was negative for GJB2 mutations. After applying exome sequencing on the proband, a missense mutation c.1378C>T (p.His460Tyr) was found in MACF1 and co-segregated with the hearing loss in the extended family. We speculated that MACF1 mutations probably cause non-syndromic hearing loss inherited in an autosomal dominant manner. The potential functional impact of the identified variant will be investigated through further analysis.
