Strengthening The Regulation Of Implementing The Authorities Of MPR
Authors: Lon Yohanes Servatius 
Published: April 2024

The “Badan Pengkajian MPR RI” is responsible for examining the state system, including the authority of the MPR. For this task, they require input from experts and academics. This article describes the Community Service activities by the Expert Team from Unika Santu Paulus Ruteng together with Group III of the Badan Pengkajian MPR RI in the framework of drafting an academic paper on the regulation of the implementation of the authority of the MPR RI. Through a focused group discussion (FGD) held in Labuan Bajo on July 11, 2023, the Experts/Academics provided their thoughts to the leaders and Members of the Badan Pengkajian MPR RI, the Secretariat General of the MPR and the Technical Committee, regarding the MPR as a crucial and strategic state institution in maintaining and monitoring the governance of all state institutions based on the pillars of Pancasila, the 1945 Constitution of the Republic of Indonesia, the Unitary State of the Republic of Indonesia, and Bhinneka Tunggal Ika. To support the role of the MPR RI, a new law is needed that regulates and explains the authority of the MPR in establishing the constitution as a constitutional basis for the state and also the authority of the MPR in establishing the GBHN as an operational basis for the nation and state. The law also stipulates the authority of the MPR in providing authentic and authoritative interpretations of the text of the law.

Introduction: 225Ac-PSMA is a promising drug for radioligand therapy (RLT) in patients with metastatic castration-resistant prostate cancer (mCRPC). Despite the large number of studies in this area, the optimal therapeutic activity of the drug is a debatable issue. The purpose of this study is to evaluate the safety of a single dose of 225Ac-PSMA at a fixed dosage (regardless of patient weight) of 6, 9 and 12 MBq.Material and methods: The study included 9 patients, 3 in each group, with mCRPC progressing against the background of standard treatment (from 1 to 6 lines of mCRPC therapy in history). The observation period was 5 weeks, instrumental, laboratory and clinical indicators were used to assess safety. 225As-PSMA was manufactured directly in the clinic in accordance with the order of the Ministry of Health of Russia 1218n dated 11/12/2020.Results: During the observation period, one patient from the group with the lowest administered activity had a serious adverse event (hospitalization due to pneumonia). When discussing this case, it was concluded that there was no connection with the drug, since pneumonia in this patient was not accompanied by leukopenia or neutropenia. All patients experienced dry mouth. In patients who received 9 and 12 MBq a decrease in the salivary gland function was recorded by scintigraphy. In two patients, severe weakness was revealed, in one of them the weakness could be associated with pneumonia, in the other patient, the weakness was most likely caused by the therapy. No cases of nephrotoxicity were recorded. Hematological toxicity was temporary reversible; no additional treatment was required in any of the cases. The most common adverse event: leukopenia, neutropenia (78 % of patients), grade III leukopenia was observed in two (22 %) patients, grade III neutropenia in one (11 %) patient.Conclusions: A single administration of 225Ac-PSMA in the studied range of activities was safe, dose-limiting toxicity was not achieved.

Published: April 2024

Purpose: To report a clinical case demonstrating difficulties of diagnosis and successful surgical treatment of myomatous type of angiomyolipoma of the liver without simultaneous damage to the kidneys.Material and methods: A female patient, 49 years old, was admitted to the hospital in August 2023, had no specific complaints, an abdominal ultrasound revealed extraperitoneal extraorgan mass in the epigastrium and mesogastrium and masses in the right lobe of liver, most likely hemangioma. The contrast-enhanced MSCT was performed on admission. Patient was rehospitalized for a surgery in September. During the operation the tumor was removed and sent for histological examination, a further immunohistochemical study was also carried out.Results: According to the results of MSCT in S3, S4, S5 of the liver oval-shaped mass (198×104×177 mm) with heterogeneous density and solid, cystic and fat features was found. Three hypovascular hypodense inclusions sizes up to 11 mm was also identified in S7/8. There was no pathologic formation in the kidneys. The liver tumor was surgically removed, the resected material was directed to a scheduled histological examination. To confirm the diagnosis an IHC analysis was also done and it revealed the expression of melanocytic (HBM-45) and smooth muscle (SMA) markers.Discussion: In this case we encountered very sparsely described in the world literature localization of angiomyolipoma — isolated hepatic one (without kidney damage). Like other authors we encountered the similarity of muomatous tumor type to the HCC and adenoma of the liver due to the characteristic features of visualization: hypervascularity, early contrast enhancement into an arterial phase and reduced density relative to the preserved parenchyma of the liver into a delayed phase of contrast.Conclusion: This case demonstrates the difficulty of diagnosing the myomatous type of AML simulating the HCC. As one of the most informative methods of diagnosis, we single out MSCT, which allowed us to think about the possibility of a benign nature of the tumor. In our case the main features excluding HCC were the absence of rapid “washout” of contrast drug, the presence of lipomatous areas and no accumulation of contrast agent by the capsule.
Beyond the Marketing Hype: Analysis of Communication Campaigns of Electric Vehicles Eco-Friendly Image and Battery Waste Concerns
Authors: Putra Aziz Sandy , Fatimah Yasmin Zein  , Rizal B. D. Herdian  
Published: April 2024

Electric Vehicles (EVs) are gaining widespread attention for their environmentally friendly nature and potential to reduce air pollution. As non-renewable fossil fuels deplete, the need for sustainable alternatives like EVs becomes imperative. The EV market emphasizes the cost-effectiveness of electric fuel and extended travel range, despite the initial higher cost of purchasing an EV. In Indonesia, the government encourages EV adoption through subsidies and improved electric refuelling infrastructure, including exempting EV users from the odd-even vehicle license plate rule in Jakarta.
To promote EV adoption, brands employ diverse marketing strategies, urging customers to embrace EVs as agents of environmental change. However, the lack of transparency in how EV brands handle nickel-based battery waste, with a limited lifespan, raises environmental concerns. The accumulation of unusable batteries could pose soil pollution risks as EV usage grows. This research aims to explore the environmental implications of battery waste from EVs in Indonesia and analyze how EV brands address these concerns in their marketing communication campaigns.
Adopting a cybernetic approach, the study examines the interconnectedness of marketing communication and consumer buying decisions. Qualitative research is utilized, drawing on various EV studies, facts about EV brand communication, and interviews with experts to provide a comprehensive analysis. Although battery waste might not be a pressing issue in Indonesia currently, inadequate waste handling raises potential future concerns about soil and water contamination. Addressing battery waste responsibly is crucial for promoting sustainable EV adoption.

⊙

and a half-light radius of 3 ± 1 pc, it is either the darkest galaxy ever discovered or the faintest self-gravitating star cluster known to orbit the Galaxy. Its line-of-sight velocity dispersion suggests the presence of dark matter, although current measurements are inconclusive because of the unknown contribution to the dispersion of potential binary stars. We use N-body simulations to show that, if self-gravitating, the system could not survive in the Milky Way tidal field for much longer than a single orbit (roughly 0.4 Gyr), which strongly suggests that the system is stabilized by the presence of large amounts of dark matter. If UMa3/U1 formed at the center of a ∼109
M
⊙ cuspy LCDM halo, its velocity dispersion would be predicted to be of order ∼1 km s−1. This is roughly consistent with the current estimate, which, neglecting binaries, places σ
los in the range 1–4 km s−1. Because of its dense cusp, such a halo should be able to survive the Milky Way tidal field, keeping UMa3/U1 relatively unscathed until the present time. This implies that UMa3/U1 is plausibly the faintest and densest dwarf galaxy satellite of the Milky Way, with important implications for alternative dark matter models and for the minimum halo mass threshold for luminous galaxy formation in the LCDM cosmology. Our results call for multi-epoch high-resolution spectroscopic follow-up to confirm the dark matter content of this extraordinary system.

Abstract
The far-infrared (FIR) opacity of dust in dark clouds within the Ophiuchus molecular cloud is investigated through multiwavelength infrared observations from UKIDSS, Spitzer, and Herschel. Employing the infrared color excess technique with both near-infrared and mid-infrared photometric data, a high-resolution extinction map in the K band (A

K
) is constructed for three dark clouds: L1689, L1709, and L1712. The derived extinction map has a resolution of

1

and reaches a depth of A

K
∼ 3 mag. The FIR optical depths τ
250 at a reference wavelength of 250 μm are obtained by fitting the Herschel PACS and SPIRE continuum data at 100, 160, 250, 350, and 500 μm using a modified blackbody model. The average dust opacity per unit gas mass at 250 μm, r
κ
250, is determined through a pixel-by-pixel correlation of τ
250 with A

K
, yielding a value of approximately 0.09 cm2 g−1, which is about 2–3 times higher than the typical value in the diffuse interstellar medium. Additionally, an independent analysis across 16 subregions within the Ophiuchus cloud indicates spatial variations in dust opacity, with values ranging from 0.07 to 0.12 cm2 g−1. Although the observed trend of increasing dust opacity with higher extinction implies grain growth, our findings indicate that rapid grain growth has clearly not yet occurred in the dark clouds studied in this work.
Giant Biconical Dust Filaments in the Starburst Galaxy NGC 1808
Authors: Kane Rohan , Veilleux Sylvain 
Published: April 2024

Abstract
We present the results from an analysis of multiwavelength archival data on the multiphase outflow in the starburst galaxy NGC 1808. We report the detection at 70 and 100 μm of dust filaments that extend up to ∼13 kpc from the galactic midplane and trace an edge-brightened biconical structure along the minor axis of the galaxy. The inner filaments are roughly cospatial with previously identified optical dust filaments, extraplanar polycyclic aromatic hydrocarbon emission, and neutral and ionized gaseous outflows. The 70/160 μm flux ratio, a proxy for the dust temperature, is elevated along the edges of the cones, indicating that the dusty medium has been driven out of the central regions of these cones and is possibly shock-heated by a large-scale outflow. We establish lower limits on the extraplanar dust mass and mean height above the stellar disk of

and ∣ z ∣ ∼ 5 kpc. The energy requirement of (5.1–9.6) × 1056 erg needed to lift the dusty material, assuming a Milky Way–like dust-to-gas ratio, can be supplied by the current starburst, with a measured star formation rate of 3.5–5.4 M
⊙ yr−1 over a timescale of (4–26) ξ
−1 Myr, where ξ is the efficiency of energy transfer. We conclude that a starburst-driven outflow is the most likely mechanism by which the dust features were formed.

Published: April 2024

Abstract
In this Letter, we examine the relationship between 3D magnetic free energy (MFE) and flaring activity using 83 major solar flares (M-class and X-class) in nine solar active regions (ARs). For this, we use 998 nonlinear force-free field extrapolations compiled by the “Institute for Space-Earth Environmental Research Database” at Nagoya University. These ARs produced at least three major flares with distinct rising and peak phases of 3D MFE. For each phase, the solar flare occurrence rate (FOR) is calculated as a ratio of the number of flares to the duration. The major results from this study are summarized as follows. First, there is no clear linear correlation (CC = 0.15) between 3D MFE and flare peak flux. Second, the FOR (3.4 day−1) of the rising phase is a little higher than that (3.1 day−1) of the peak phase, depending on AR. Third, for several flares, there are noticeable decreases in 3D MFE, which correspond to the typical energy of a major flare (about 1032 erg). Fourth, it is interesting to note that there are noticeable enhancements in FORs at several local maxima of 3D MFE, which may be associated with flux emergence and/or shearing motions. Fifth, the flare index rates, which are defined as the summation of flaring activity divided by the duration, of rising and peak phases are 151 day−1 and 314 day−1, respectively. Our results imply that the traditional and simple “storage and release” model does not apply to flare activities, and the random perturbation may be important for triggering flares.

Abstract
We present observations obtained with the Near Infrared Spectrograph on JWST of the five Jupiter Trojans that will be visited by the Lucy spacecraft—the Patroclus–Menoetius binary, Eurybates, Orus, Leucus, and Polymele. The measured 1.7–5.3 μm reflectance spectra, which provide increased wavelength coverage, spatial resolution, and signal-to-noise ratio over previous ground-based spectroscopy, reveal several distinct absorption features. We detect a broad OH band centered at 3 μm that is most prominent on the less-red objects Eurybates, Patroclus–Menoetius, and Polymele. An additional absorption feature at 3.3–3.6 μm, indicative of aliphatic organics, is systematically deeper on the red objects Orus and Leucus. The collisional fragment Eurybates is unique in displaying an absorption band at 4.25 μm that we attribute to bound or trapped CO2. Comparisons with other solar system small bodies reveal broad similarities in the 2.7–3.6 μm bands with analogous features on Centaurs, Kuiper Belt objects (KBOs), and the active asteroid 238P. In the context of recent solar system evolution models, which posit that the Trojans initially formed in the outer solar system, the significant attenuation of the 2.7–3.6 μm absorption features on Trojans relative to KBOs may be the result of secondary thermal processing of the Trojans’ surfaces at the higher temperatures of the Jupiter region. The CO2 band manifested on the surface of Eurybates suggests that CO2 may be a major constituent in the bulk composition of Trojans, but resides in the subsurface or deeper interior and is largely obscured by refractory material that formed from the thermophysical processes that were activated during their inward migration.

La communication des gouvernements locaux sur les plateformes de médias sociaux : affinage et évaluation des schémas d’adoption en Belgique
Authors: Mabillard Vincent , Zumofen Raphaël , Pasquier Martial 
Published: April 2024

Cet article s’appuie sur la littérature relative à l’adoption des nouvelles technologies et sur des études empiriques portant sur l’adoption des médias sociaux dans le secteur public pour analyser le cas des municipalités belges. Notre objectif est triple : (a) proposer une nouvelle approche pour évaluer l’adoption des plateformes de médias sociaux par les gouvernements, (b) décrire la situation en Belgique à travers le concept d’« adoption active » et (c) déterminer les principaux facteurs liés à l’adoption de Facebook dans les communes belges de plus de 10 000 habitants. Pour atteindre ces objectifs, nous avons utilisé un logiciel pour récupérer des données quantitatives concernant l’adoption et l’institutionnalisation de Facebook. Nos résultats révèlent que la taille de la commune, l’âge médian et la longévité sur la plateforme sont positivement associés à l’adoption de Facebook. En revanche, le revenu médian est, étonnamment, associé négativement à plusieurs dimensions de l’adoption active. Ces résultats contribuent à la littérature sur les facteurs liés à l’utilisation des médias sociaux. En outre, les nouvelles façons de comprendre les modèles d’adoption et d’institutionnalisation offrent une approche conceptuelle solide et des pistes intéressantes de recherche. Pour les praticiens, notre étude offre aux municipalités un nouveau modèle d’évaluation de l’adoption des réseaux sociaux, soulignant la différence fondamentale entre l’inscription et « l’adoption active ». Remarques à l’intention des praticiens Cet article propose une nouvelle approche pour évaluer l’adoption des médias sociaux et les modèles d’institutionnalisation dans les organisations publiques. Il offre un cadre d’évaluation de l’adoption des réseaux sociaux, soulignant la différence fondamentale entre l’inscription et « l’adoption active ». Il identifie également les principaux facteurs liés à l’adoption de Facebook dans les communes belges de plus de 10 000 habitants : la taille de la population, l’âge médian, le revenu médian et les variables liées aux réseaux sociaux – c’est-à-dire l’activité sur Twitter et Instagram – ainsi que la longévité sur la plateforme.
Confinement, qualité de l’information et confiance politique : une étude empirique du confinement à Shanghai sous le COVID-19
Authors: Zhai Yida , Han Guanghua 
Published: April 2024

De nombreux pays ont adopté diverses mesures pour freiner la propagation de la pandémie de COVID-19. Les mesures réglementaires de confinement ont entraîné des changements dans la confiance politique du public envers le gouvernement (y compris dans sa compétence, sa bienveillance et son intégrité). L’information influence les opinions et les valeurs des résidents ; ce document vise à étudier l’effet d’un confinement sur la confiance politique et l’effet modérateur de la qualité de l’information partagée par le gouvernement. Du 12 mars au 31 mai 2022, Shanghai a mis en place des mesures strictes de confinement. Dans cette étude, nous avons échantillonné au hasard les informations de participation de 1063 participants. L’analyse de régression basée sur les données montre que le confinement a eu un impact négatif sur toutes les sous-catégories de confiance politique. Cependant, les informations opportunes et précises affaiblissent cet effet négatif. L’exactitude de l’information modère la relation entre le confinement et la confiance politique dans la compétence et l’intégrité, tandis qu’une quantité suffisante d’informations modère la relation entre le confinement et la confiance politique dans la bienveillance. Remarques à l’intention des praticiens Cette étude explore comment les différentes dimensions de la qualité de l’information affectent la confiance politique de chaque composante publique, et incite ainsi les praticiens à améliorer stratégiquement la communication de l’information en cas de crise.
Labellisation et fabrique urbaine
Authors: Rotolo Marina 
Published: April 2024

Depuis plusieurs années, de plus en plus de villes rivalisent d’ingéniosité pour obtenir le titre de « Capitale européenne de la culture ». Ce label a en effet été synonyme d’un renouveau économique et d’une politique de régénération urbaine pour des villes comme Glasgow (1990), Lille (2004) ou Liverpool (2008). En s’appuyant sur le cas singulier de Matera, ville moyenne d’Italie méridionale doublement labellisée (patrimoine mondial de l’Unesco en 1993 et Capitale européenne de la culture en 2019), cette étude entraîne le lecteur dans les coulisses du processus de labellisation. L’arrière-scène est ici analysée sous un triple aspect : les jeux d’acteurs, les représentations urbaines et les projets de transformation de la ville. Animée par l’envie de « suivre à la trace » les interactions et les jeux de pouvoir à l’œuvre dans ce processus de labellisation, Marina Rotolo propose une approche originale permettant de dépasser les études déjà parues sur le sujet, traditionnellement axées sur l’évaluation des impacts du label culturel. Cet ouvrage richement illustré convoque plusieurs disciplines (architecture, histoire urbaine, anthropologie) et mobilise des sources inédites et variées. Dans une ère définie par la compétition internationale et une concurrence accrue entre les villes, où les métropoles dominent, il questionne plus globalement les effets de la labellisation sur la fabrique urbaine des villes moyennes, à l’image de Bourges, récemment désignée Capitale européenne de la culture 2028.
Pêche à l’hameçon

Published: April 2024

L’étude techno-fonctionnelle d’hameçons en os mésolithiques retrouvés dans les fjords et sur la côte de l’ouest de la Norvège permet de renseigner la pratique de la pêche et son évolution (8 000-4 000 BC). Bien que l’analyse de la chaîne opératoire indique une continuité dans la tradition technique, des hameçons typologiquement différents semblent se succéder au cours du Mésolithique. Les différences morphologiques observées (répartition des volumes, localisation des encoches, dimensions) sont questionnées en couplant une étude statistique morphométrique et une analyse technologique des hameçons. Les transformations observées sur l’outillage sont corrélées à des évolutions dans la pratique de la pêche, avec une intensification de l’exploitation des ressources aquatiques.
