Authors: Tarigan Samuel
Published: January 2024

Studi ini bertujuan untuk mengidentifikasi pola preferensi penggunaan mobile phone khususnya use cases, media sosial, dan messaging application dalam sebuah perguruan tinggi, serta mendemonstrasikan secara visual perbedaan pola penggunaan oleh sub-segmen dosen/staff dari sub-segmen mahasiswa menggunakan metode Correspondence Analysis. Hasil penelitian menunjukkan bahwa pemanfaatan mobile phone tertinggi adalah untuk komunikasi, pembelajaran daring, dan media sosial. Sedangkan preferensi media sosial secara berurutan adalah Instagram, Tiktok, dan diikuti oleh Facebook. Selain itu, tiga messaging application yang paling banyak dimanfaatkan adalah Whatsapp, Line, dan email. Penelitian ini juga menunjukkan bahwa terdapat perbedaan pola penggunaan di antara dosen/staff dengan mahasiswa baik dalam hal use case, aplikasi media sosial, maupun messaging application. Dari sisi teoretis, penelitian ini menunjukkan bahwa Correspondence Analysis memiliki keunggulan dalam hal visualisasi relasi antar variabel yang relatif mudah dicerna, namun juga memiliki kelemahan dalam hal interpretasi yang berpotensi misleading, bila tidak dibandingkan dengan beberapa metode visualisasi/analisis lainnya. Secara praktikal, hasil penelitian ini dapat dimanfaatkan oleh operator telekomunikasi dan application developer untuk pengembangan produk, serta oleh digital marketer dalam memilih jenis channel yang paling sesuai untuk segmen perguruan tinggi

Indonesia is an island nation whose two-thirds of its territory is water and is located in a strategic location because it is on a cross of world trade routes; therefore, the role of the port as a marine transportation system is crucial in supporting economic growth. The stacking field used to serve container cargo is one of the main port facilities to store containers originating from ships or going to ships. A buildup field is needed to prevent the risk of ship delay, which results in decreased loading and unloading production and the time of ships and goods being ported for a prolonged time. Makassar New Port is the largest seaport in the Eastern Region of Indonesia. Located in the Makassar Strait, Makassar New Port holds a leading role in the distribution of goods equipped with loading and unloading facilities to and from the ship to the receiving warehouse. This study aims to analyze the fertilization field's capacity for both the operator and the user. The result of this study obtained for the short-term optimum cost Container Yard in Makassar New Port is IDR 1.687.795.482.144 with the width of field dimension is 530.000 m2 . While for the Medium Term optimum cost is IDR 1.688.202.882.750 with the width of field dimension is 530.000 m2 and Long Term is IDR 1.689.520.940.921 with the field dimension is 535.000 m2.Times

Abstrak

Penggunaan bahan bakar minyak untuk menghasilkan panas atau tenaga dalam dunia industri masih menjadi fokus perhatian para peneliti. Kualitas bahan bakar, performa, emisi, dan faktor ekonomis menjadi beberapa parameter yang perlu diperhatikan dari berbagai macam jenis bahan bakar. Di Indonesia terdapat beberapa jenis bahan bakar diesel diantaranya, Pertamina Dex, Dexlite dan Biosolar (B30). Bahan bakar tersebut tentunya memiliki karakteristik yang berbeda-beda. Untuk dapat mengetahui karakter bahan bakar tersebut perlu dilakukan pengujian bahan bakar pada mesin diesel. Pada penelitian ini, dilakukan eksperimen penggunaan bahan bakar tersebut pada mesin diesel merk Jianfa daya 7 HP tipe R175A tanpa beban dengan berbagai variasi rpm yaitu 1000, 1200, 1400, 1600, 1800, 2000, 2200. Ekperimen berlaku pada tiga jenis bahan bakar yaitu Biosolar (B30), Pertamina Dex, dan Dexlite. Konsumsi diukur dalam satuan waktu (detik) per 50 mili liter. Dari eksperimen, didapatkan hasil bahwa Biosolar (B30) menempati posisi terendah dibuktikan dengan durasi waktu untuk menghabiskan 50 mili liter pada 2000 rpm hanya butuh waktu 49 detik, dexlite 63 detik sedangkan Pertamina Dex 70 detik. Sehingga dapat disimpulkan bahwa Pertamina Dex paling hemat dibandingkan dengan Dexlite dan Biosolar (B30).

Published: January 2024

Lead contamination and subsequent degradation of the affected soil is a global environmental issue. Besides the natural weathering processes, the chief ways in which of lead contaminates the environment are anthropogenic. The plants which grow on such lead contaminated soils can uptake the heavy metal and translocate it to the various parts both in the intracellular and extracellular fashion. Lead toxicity can affect the overall plant health as it impacts basic physiological and metabolic processes such as germination, uptake of nutrients and minerals, photosynthesis, respiration, oxidative metabolism, mitosis etc. Plants in response to this toxicity can develop a certain degree of tolerance via passive and inducible mechanisms. These mechanisms have been exploited in the new era technology of phytoremediation which aims at a sustainable cleansing of lead contaminated soils by using plants. Aromatic plants because of their low risk of contamination in products consumption and a high demand over supply aspects are a suitable choice of plants that can be used for phytoremediation. This review addresses the aspects of lead contamination and its sources, the uptake of lead by plants, lead toxicity in plants, and the consequent tolerance developed as well as the potential and advantages of using aromatic plants for phytoremediation of soils which are contaminated with lead.

Published: January 2024

Menthol mint, corn mint, Japanese mint or Mentha arvensis belongs to the family Lamiaceae, which is known as the mint family. The genus name ‘Mentha’ is derived from the Greek word minthos meaning herb mint and ‘arvensis’ means ploughed field (Takeda, 1971). The cultivation of Mentha arvensis was initially started around 1870 in Japan, so it is also called as Japanese mint, that is believed to be the native place of this plant. The cultivation was gradually spread to other countries like Brazil, China, France, Italy and U.S.A. This paper traces the evolution of menthol mint introduction, cultivation & trade in India.

A national labor action is a form of protest carried out by workers to demand their rights that are considered unfulfilled. The national labor action that occurred in 2023 in Indonesia had a significant impact on various sectors, including the industrial sector. One of the impacts that arose was the decline in employee performance in several affected companies. The research method used is the descriptive qualitative method. Descriptive qualitative research aims to describe and illustrate existing phenomena. Thus, it can be concluded that the workers are disappointed with the injustice in terms of the wages given, they feel that the wages/salaries given are not proportional to the performance they put out. This reason is a factor in the workers’ insistence on getting an increase in their wages. Overall, the workers’ national labor action was based on dissatisfaction with the wages given to workers in Indonesia, giving rise to the national labor action. In this context, the calculation of inflation, economic growth, and the current need for a decent living are important factors that must be considered in raising wage increases for workers. These factors can also affect the work stress and welfare of the workers.  The speech action this time conveyed two demands, namely the revision of the DKI UMP from 3.6% to 15% and the implementation of the minimum wage under the Jakarta Labor Law.

Lieux d’une parole autre : hétérotopie et hétérologie dans Le Chat dans le sac et Masculin féminin
Authors: Constantin Caille Antoine
Published: January 2024

Sont étudiées deux oeuvres cinématographiques – Le Chat dans le sac (Gilles Groulx, 1964) et Masculin féminin (Jean-Luc Godard, 1966) – permettant d’élaborer une conception complexe du dialogue et de son inscription dans l’espace social. Le concept d’hétérotopie, emprunté à Michel Foucault, est utilisé afin de désigner l’espace autre que les (inter)locuteurs doivent constituer pour donner lieu à leur dialogue, mais aussi les espaces autres qu’ils tentent de trouver pour créer un discours à l’abri des dialogues délétères. Le concept d’hétérologie, traduction proposée par Tzvetan Todorov d’un mot russe (raznorečie) créé par Mikhaïl Bakhtine, permet de faire ressortir non seulement la différence entre les discours des interlocuteurs, mais aussi celle des discours prononcés par la voix d’un même personnage. En portant attention à ce que Michel Chion appelle « la mise en scène de la voix au cinéma », nous discernerons des procédés cinématographiques qui hétérogénéisent l’espace du discours. Le travail sur la synchronisation et la désynchronisation des visages parlants et des voix, sur l’acousmatisation et la désacousmatisation, donne à penser le dialogue comme un problème de différenciation personnelle au sein de la société, et par-delà ses possibilités actuelles.
De Roberto Rossellini à Gilles Carle : la réalité par la parole
Authors: Dubois Sylvie
Published: January 2024

La question des dialogues pour un cinéma qui vise une forme de révélation de la réalité peut constituer un point de divergence entre les réalisateurs, au regard des pratiques cinématographiques. Divergence que l’on peut retrouver entre le cinéma de Gilles Carle, considéré comme réalisateur de documentaires d’auteur, et les potentielles influences du néoréalisme italien sur celui-ci. Traitant de l’immigration avec Dimanche d’Amérique (1961), il existe un autre film, du genre néoréaliste, pouvant se placer en miroir de celui-ci. Il s’agit de Stromboli (1950) de Roberto Rossellini. La manière d’enregistrer les dialogues, en postsynchronisation, peut paraître opposée à un cinéma qui se veut néo-réaliste et souhaite notamment laisser place à l’intervention du réel en sortant des studios. Le film de Gilles Carle, essentiellement tourné en son direct, s’il a pu être inspiré par les films néoréalistes, dont Stromboli de Roberto Rossellini, permet de penser la présence de la réalité au travers de dialogues enregistrés en direct ou postsynchronisés. Le présent article souhaite ainsi exposer cette réflexion au travers d’une analyse comparative, technique et esthétique, de ces deux films, afin d’en extraire les liens sur la mise en scène de la parole au cinéma.
Le doublage cinématographique au Québec : quand la culture de la société d’accueil s’exprime dans des oeuvres étrangères
Authors: Sabino-Brunette Hubert
Published: January 2024

Le doublage, mode de traduction qui s’est imposé au Québec, modifie de différentes manières le rapport du public aux films. En se concentrant sur l’analyse de la traduction québécoise de la trilogie néerlandaise Flodder (Dick Mass, 1986, 1992, 1993), devenue la trilogie des Lavigueur, cet article fait ressortir que le doublage permet d’ajouter des références culturelles propres au Québec, allant parfois même jusqu’à effacer des éléments représentatifs de la culture initiale. Il en résulte alors une sorte d’oeuvre hybride étrangement locale, bien que localement étrangère. Ainsi, cet article entend participer à démontrer que le doublage, bien qu’il permette à des pays exportateurs de films de conquérir le marché québécois, se présente également comme une forme de résistance dans un contexte de mondialisation et participe à la culture québécoise, à même les films et en marge de ceux-ci.
« Tenir, servir et lutter, parfois jusqu’à l’absurde. » Essai de statistiques historiques sur la production et la distribution cinématographiques à l’Office du film du Québec (1961-1975)
Authors: Robert Marc-André
Published: January 2024

L’Office du film du Québec (OFQ) fut, entre 1961 et 1983, le principal organisme de production et de distribution cinématographiques de l’État québécois servant les ministères et services gouvernementaux. Faute d’études sur le sujet, on dispose de bien peu d’information sur ce produit unique de la Révolution tranquille. Déjà en 1981, les chercheurs Yvan Lamonde et Pierre-François Hébert soulignaient l’importance de colliger les données de production cinématographique de l’Office du film du Québec. Cet article se veut donc une première amorce en la matière. Il dresse un portrait analytique, quantitatif et qualitatif de la production et de la distribution cinématographiques à l’Office du film du Québec pour la période comprise entre 1961 et 1975. À partir notamment des données extraites des rapports annuels de l’organisme, en les situant dans leur contexte historique respectif, il est possible de désigner trois grandes phases significatives qui permettent de comprendre l’évolution de l’OFQ dans le temps alors que s’opère, en filigrane, le retrait progressif de l’État québécois dans la production cinématographique québécoise. En ressort surtout le clivage entre la perception des administrateurs de l’OFQ en regard à l’importance de la production cinématographique de l’État et celle des gouvernements.
Las representaciones femeninas en el Arte Levantino del Bajo Aragón, Maestrazgo y Bajo Ebro
Authors: Fernández Macías Laura , Santos da Rosa Neemias , Díaz-Andreu Margarita
Published: January 2024

Desde los inicios de la investigación sobre el arte rupestre levantino, sus representaciones femeninas sólo han sido estudiadas superficialmente. Unos primeros trabajos específicos extensos aparecieron en los 1990, impulsados por la introducción de la arqueología de género y feminista en España, criticándose en ellos el marcado sesgo androcéntrico del análisis e interpretación de estos motivos. Este artículo propone un nuevo enfoque de las representaciones femeninas en el arte levantino. Revisamos los atributos y características para la identificación sexual de los antropomorfos y aplicamos estos criterios en la determinación de qué figuras en nuestra zona de estudio, el Bajo Aragón, el Maestrazgo y el Bajo Ebro, pueden clasificarse como femeninas. Clasificamos estilísticamente estas figuras según los morfotipos previamente establecidos para este territorio, terminando nuestro estudio analizando los paneles con imágenes femeninas para identificar el papel que la mujer desarrolló en estos espacios simbólicos y en la sociedad levantina.

Nuevo estudio de los conjuntos rupestres del Barranco de Gibert I y II (Mosqueruela, Teruel) y su contextualización arqueológica en el Maestrazgo
Authors: Bea Martínez Manuel , Domingo Sanz Inés , Román Monroig Dídac , Angás Pajas Jorge
Published: January 2024

La nueva documentación llevada a cabo en los abrigos de Barranco de Gibert I y II (Mosqueruela, Teruel), con representaciones clasificables dentro del ciclo Levantino y Esquemático/Abstracto, ha permitido registrar nuevos motivos no identificados hasta el momento, así como plantear la reinterpretación de algunas representaciones ya conocidas. Para el conjunto Levantino (Barranco Gibert I) se ofrece una nueva lectura de la composición escénica sugiriendo una posible interpretación como una escena bélica. La homogeneidad estilística de los motivos conservados en el panel permite clasificar sus representaciones dentro del tipo Lineal/Cingle, bien documentado en conjuntos del entorno regional y característicos de las fases finales de la secuencia levantina. La plasmación de un tocado de antenas en el motivo principal del conjunto lo pone en relación con el restringido conjunto de motivos con este tipo de tratamiento, enfatizando el carácter regional del mismo al ser representativo de estos territorios.
La identificación del dios Reove y otras correcciones en el altar sacrificial de marecos (Penafiel): una ofrenda a las divinidades del cielo para acabar con la sequía
Authors: Olivares Pedreño Juan Carlos
Published: January 2024

El presente trabajo se basa en un estudio sobre el terreno del altar hallado en Marecos, en el que se ofecen varios animales sacrificados a divinidades locales de la región lusitano-galaica y a Júpiter. Se llevó a cabo un análisis riguroso del monumento que permitió identificar una deidad que, hasta el momento, no se había podido ver entre las veneradas en el altar: el dios estelar Reove. A partir de esta identificación se pudo descubrir su apelativo, así como el de la última deidad mencionada, además de plantear una nueva interpretación sobre la datación de las ofrendas. Finalmente, se desarrolla la hipótesis de que la causa que motivó todo el ritual sacrificial fue una petición de lluvia a las deidades estelares para acabar con un período de sequía.

Published: January 2024

O tema e o conteúdo do livro BR-163 em 5 tempos: uma abordagem geo-foto-gráfica têm caráter essencialmente geográfico, o que desperta o interesse não somente de geógrafos, mas também de profissionais de outras áreas de conhecimento e interessados no tema da Amazônia Brasileira. A análise desenvolvida pelo autor está centrada num dos conceitos chaves da Geografia que é o de paisagem, o qual é empregado no decorrer de toda a obra como ferramenta de diálogo entre as ciências naturais e as ciências sociais em torno de questões socioambientais que envolvem a BR-163. A obra mostra, por meio de fotos e mapas, como a ‘paisagem geo-foto-gráfica’ se constitui num indicador dos processos de antropização de territórios emergentes e como a paisagem pode ser uma ferramenta de análise das dinâmicas espaciais na interface natureza-sociedade, a partir de processos relacionados à ocupação, à instalação de atividades econômicas, à atuação de órgãos governamentais, à marginalização de colonos pobres atraídos para a região e ao comprometimento da sobrevivência de populações indígenas nas áreas situadas nas zonas de influência do eixo da BR-163, entre Cuiabá e Santarém.

Evolutionary shifts from egg-laying (oviparity) to live birth (viviparity) are common across diverse taxa, and some species exhibit variability in egg-laying modes or an intermediate mode with eggs containing embryos at various stages of development. How such natural quantitative variation in egg retention arises through differences in genetics, behaviour, and physiology – and how this variation ultimately connects to variation in specific fitness components – remains poorly understood. Here, we investigate intraspecific variation in egg retention in the nematode
Caenorhabditis elegans
using a panel of 316 wild strains. We observe highly variable intra-uterine egg retention, with some strains exhibiting strongly reduced or increased retention with internal hatching. We identify multiple evolutionary origins of these phenotypic extremes and pinpoint candidate loci responsible for the observed variation. Analysis of a subset of strains confirms that natural variation in egg-laying behaviour contributes to differences in egg retention. Using neuromodulatory agents and CRISPR-
Cas9
-mediated genetic manipulation, we demonstrate that this behavioural variation arises from an evolutionarily divergent neuromodulatory architecture in the egg-laying circuitry. In addressing the question of why natural variation in
C. elegans
egg retention is maintained, we find that strong egg retention can reduce maternal fertility and survival due to detrimental hatching
in utero
. However, genotypes with strong egg retention may benefit from improved offspring protection against environmental insults and gain a competitive advantage with offspring exhibiting a shortened development time to reproductive maturity outside the uterus. The observed natural variation in egg-laying behaviour in
C. elegans
could therefore reflect modifications of a trade-off between alternative fitness components across generations. Our study reveals previously underappreciated diversity in the
C. elegans
egg-laying circuit and provides insights into the fitness consequences of this behavioural variation. We propose that intraspecific variation in nematode egg-laying behaviour offers an ideal system to identify molecular changes underlying evolutionary transitions between oviparity and viviparity in invertebrates.

Rapid lymphocyte cell division places enormous demands on the protein synthesis machinery. Flow cytometric measurement of puromycylated ribosome-associated nascent chains after treating cells or mice with translation initiation inhibitors reveals that ribosomes in resting lymphocytes
in vitro
and
in vivo
elongate at typical rates for mammalian cells. Intriguingly, elongation rates can be increased up to 30% by activation
in vivo
or fever temperature
in vitro
. Resting and activated lymphocytes possess abundant monosome populations, most of which actively translate
in vivo,
while
in vitro,
nearly all can be stalled prior to activation. Quantitating lymphocyte protein mass and ribosome count reveals a paradoxically high ratio of cellular protein to ribosomes insufficient to support their rapid
in vivo
division, suggesting that the activated lymphocyte proteome
in vivo
may be generated in an unusual manner. Our findings demonstrate the importance of a global understanding of protein synthesis in lymphocytes and other rapidly dividing immune cells.

The transcription factor Bcl11b has been linked to neurodevelopmental and neuropsychiatric disorders associated with synaptic dysfunction. Bcl11b is highly expressed in dentate gyrus granule neurons and is required for the structural and functional integrity of mossy fiber-CA3 synapses. The underlying molecular mechanisms, however, remained unclear. We show that the synaptic organizer molecule C1ql2 is a direct functional target of Bcl11b that regulates synaptic vesicle recruitment and long-term potentiation at mossy fiber-CA3 synapses
in vivo
and
in vitro
. Furthermore, we demonstrate C1ql2 to exert its functions through direct interaction with a specific splice variant of neurexin-3, Nrxn3(25b+). Interruption of C1ql2-Nrxn3(25b+) interaction by expression of a non-binding C1ql2 mutant or by deletion of Nrxn3 in the dentate gyrus granule neurons recapitulates major parts of the Bcl11b as well as C1ql2 mutant phenotype. Together, this study identifies a novel C1ql2-Nrxn3(25b+)-dependent signaling pathway through which Bcl11b controls mossy fiber-CA3 synapse function. Thus, our findings contribute to the mechanistic understanding of neurodevelopmental disorders accompanied by synaptic dysfunction.

Hox gene clusters encode transcription factors that drive regional specialization during animal development: for example the Hox factor Ubx is expressed in the insect metathoracic (T3) wing appendages and differentiates them from T2 mesothoracic identities. Hox transcriptional regulation requires silencing activities that prevent spurious activation and regulatory crosstalks in the wrong tissues, but this has seldom been studied in insects other than Drosophila, which shows a derived Hox dislocation into two genomic clusters that disjoined Antennapedia (Antp) and Ultrabithorax (Ubx). Here, we investigated how Ubx is restricted to the hindwing in butterflies, amidst a contiguous Hox cluster. By analysing Hi-C and ATAC-seq data in the butterfly Junonia coenia, we show that a Topologically Associated Domain (TAD) maintains a hindwing-enriched profile of chromatin opening around Ubx. This TAD is bordered by a Boundary Element (BE) that separates it from a region of joined wing activity around the Antp locus. CRISPR mutational perturbation of this BE releases ectopic Ubx expression in forewings, inducing homeotic clones with hindwing identities. Further mutational interrogation of two non-coding RNA encoding regions and one putative cis-regulatory module within the Ubx TAD cause rare homeotic transformations in both directions, indicating the presence of both activating and repressing chromatin features. We also describe a series of spontaneous forewing homeotic phenotypes obtained in Heliconius butterflies, and discuss their possible mutational basis. By leveraging the extensive wing specialization found in butterflies, our initial exploration of Ubx regulation demonstrates the existence of silencing and insulating sequences that prevent its spurious expression in forewings.

Spinal Muscular Atrophy (SMA) is a neuromuscular disorder characterized by the deficiency of the survival motor neuron (SMN) protein, which leads to motor neuron dysfunction and muscle atrophy. In addition to the requirement for SMN in motor neurons, recent studies suggest that SMN deficiency in peripheral tissues plays a key role in the pathogenesis of SMA. Using limb mesenchymal progenitor cells (MPCs)-specific SMN-depleted mouse models, we reveal that SMN reduction in chondrocytes and fibro-adipogenic progenitors (FAPs) derived from limb MPCs causes defects in the development of bone and neuromuscular junction (NMJ), respectively. We showed that impaired growth plate homeostasis, which causes skeletal growth defects in SMA, is due to reduced IGF signaling from chondrocytes rather than the liver. Furthermore, the reduction of SMN in FAPs resulted in abnormal NMJ maturation, altered release of neurotransmitters, and NMJ morphological defects. Transplantation of healthy FAPs rescued the morphological deterioration. Our findings highlight the significance of mesenchymal SMN in neuromusculoskeletal pathogenesis in SMA and provide insights into potential therapeutic strategies targeting mesenchymal cells for the treatment of SMA.

CC-chemokine ligand 2 (CCL2) is involved in the pathogenesis of several diseases associated with monocyte/macrophage recruitment, such as HIV-associated neurocognitive disorder (HAND), tuberculosis, and atherosclerosis. The rs1024611 (alleles:A>G; G is the risk allele) polymorphism in the
CCL2 cis
-regulatory region is associated with increased CCL2 expression in vitro and ex vivo, leukocyte mobilization in vivo, and deleterious disease outcomes. However, the molecular basis for the rs1024611-associated differential CCL2 expression remains poorly characterized. It is conceivable that genetic variant(s) in linkage disequilibrium (LD) with rs1024611 could mediate such effects. Previously, we used rs13900 (alleles: C>T) in the
CCL2
3’ untranslated region (3’ UTR) that is in perfect LD with rs1024611 to demonstrate allelic expression imbalance (AEI) of
CCL2
in heterozygous individuals. Here we tested the hypothesis that the rs13900 could modulate
CCL2
expression by altering mRNA turnover and/or translatability. The rs13900 T allele conferred greater stability to the
CCL2
transcript when compared to the rs13900 C allele. The rs13900 T allele also had increased binding to Human Antigen R (HuR), an RNA-binding protein, in vitro and ex vivo. The rs13900 alleles imparted differential activity to reporter vectors and influenced the translatability of the reporter transcript. We further demonstrated a role for HuR in mediating allele-specific effects on CCL2 expression in overexpression and silencing studies. The presence of the rs1024611G-rs13900T conferred a distinct transcriptomic signature related to inflammation and immunity. Our studies suggest that the differential interactions of HuR with rs13900 could modulate CCL2 expression and explain the interindividual differences in CCL2-mediated disease susceptibility.
