Published: January 2025

<p><em>The goalkeeper robot developed by STMIK Banjarbaru still faces challenges in improving the response to the ball to reduce the possibility of goals being scored by opposing robots. The ability of the robot keeper is currently limited to the starting point of the ball so that when the ball bounces toward the goal, the robot has not been able to predict the end point of the ball, resulting in the movement of the goalkeeper robot, which is sometimes slow in blocking the ball. This research was conducted to develop a detection system of a ball direction using the optical flow method. The Logitech C270 series web camera device is used on a robot with a laptop as a video data processor using Python language. The results show that this system is capable of detecting balls in all five directions or quadrants, including 90°, 135°, 180°, 225°, and 270. The detection results of these directions are represented as position information data, such as a ball in a state of still, right, bottom right, top right, left, top left, bottom left, top, and bottom. </em></p><p><strong><em>Keywords:</em></strong><em> goalkeeper; response; ball direction; robot motion;</em></p><p align="center"> </p><p align="center"><strong>Abstrak</strong></p><p>Robot Penjaga gawang yang dikembangkan oleh STMIK Banjarbaru masih menghadapi tantangan dalam meningkatkan respon terhadap bola agar dapat mengurangi kemungkinan terjadinya gol oleh robot lawan.

<p><em>Celery plants have many benefits, both as food ingredients such as soup and herbal medicine for various diseases such as fever, flu, digestive disorders, and hypertension. However, celery watering by farmers is still done manually, which often causes suboptimal plant growth due to incorrect water measurements. Changes in soil moisture are also a problem, especially when farmers cannot water regularly. This study uses the Research and Development (R&amp;D) method and produces an automatic sprinkler with a Soil Moisture sensor that detects soil moisture. If the humidity drops below 65%, the water pump will turn on, and if the humidity rises above 75%, the pump will turn off. These settings can be controlled via the Telegram application with the command "/pompan_on" to water, "/pompan_off" to stop, and "/cek-kelm_tanah" to check soil moisture.</em></p><p><strong><em>Keywords:</em></strong><em> Celery; Automatic; Sprinkler; Telegram; Soil Moisture</em></p><p align="center"><strong> </strong></p><p align="center"><strong>Abstrak</strong></p><p>Tanaman seledri memiliki banyak manfaat, baik sebagai bahan makanan seperti sup maupun obat herbal untuk berbagai penyakit seperti demam, flu, gangguan pencernaan, dan hipertensi.

Abstract

The menstrual cycle is an important indicator of women's reproductive health (Omidvar et al., 2018). According to the research conducted at SMA Negeri 6 Tangerang, a higher proportion of irregular menstrual cycles was found, amounting to 59.4%. The impacts of irregular menstruation include infertility, endometriosis, and psychological disorders (Ilmi & Selasmi, 2019). The current target of the researchers is adolescents because adolescent reproductive health, especially regarding the menstrual cycle, is necessary for reproductive health readiness in adulthood.
The research method used is descriptive quantitative with a cross-sectional approach. The research respondents are high school students. The purpose of this study is to determine adolescent reproductive health related to nutritional status, physical activity, and anxiety with the menstrual cycle in high school.
The study results showed that the majority experienced irregular menstrual cycles, with 74 respondents (78.7%). The three variables studied, namely nutritional status, physical activity, and stress among high school students, showed no difference in proportion. This is because, during adolescence, the body adapts to hormonal changes during puberty, so the menstrual cycle still varies. This is considered normal. As age increases, the menstrual cycle will stabilize and become regular, especially after age 20 (Musmiah, 2018).
During data collection, it was found that respondents still did not understand how to calculate the menstrual cycle, so efforts are needed to increase knowledge and understanding of their menstrual cycles.

Published: January 2025

La didáctica ha evolucionado con el pasar de los años, desde una instrucción muy rígida y monótona hasta llegar a una instrucción participativa y centrada en el estudiante, la misma que dispone de una gran variedad de recursos tecnológicos. Hoy en día, es evidente encontrar procesos pedagógicos que emplean diferentes formas de instrucción direccionados a responder a las demandas de la sociedad y también a la globalización. El propósito de este artículo es analizar desde diferentes perspectivas qué es la didáctica y cuál es su relación con el proceso enseñanza-aprendizaje y con el desarrollo del conocimiento, considerando la epistemología, sus enfoques, paradigmas y la tecnología. Para el desarrollo de este trabajo se realizó un análisis bibliográfico profundo, el mismo que permitió generar nueva información sobre cómo se adquiere el conocimiento en los entornos académicos. Se concluye afirmando que la praxis de la didáctica ha permitido tanto la formación de las personas como el desarrollo de las sociedades, y para ello los docentes han debido usar una serie de métodos, técnicas y estrategias direccionadas a facilitar la adquisición de los saberes. Se destaca también que, en la actualidad, la educación requiere el empleo de herramientas tecnológicas que permitan que el proceso sea más eficaz y eficiente.

Abstract
We present a joint analysis of transit timing variations (TTVs) and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known TTVs, with a peak-to-node amplitude of ∼2 days, the largest value ever observed, and a superperiod of ~930 days. TOI-4504 b and c were identified in public Transiting Exoplanet Survey Satellite (TESS) data, while the TTVs observed in TOI-4504 c, together with radial velocity (RV) data collected with FEROS, allowed us to uncover a third, nontransiting planet in this system, TOI-4504 d. We were able to detect transits of TOI-4504 b in the TESS data with a period of 2.4261 ± 0.0001 days and derive a radius of 2.69 ± 0.19 R
⊕. The RV scatter of TOI-4504 was too large to constrain the mass of TOI-4504 b, but the RV signals of TOI-4504 c and d were sufficiently large to measure their masses. The TTV+RV dynamical model we apply confirms TOI-4504 c as a warm Jupiter planet with an osculating period of 82.54 ± 0.02 days, a mass of 3.77 ± 0.18 M
J, and a radius of 0.99 ± 0.05 R

J. We present the discovery of a system with three exoplanets: a hot sub-Neptune and two warm Jupiter planets. The gas giant pair is stable and likely locked in a first-order 2:1 mean-motion resonance (MMR). The TOI-4504 system is an important addition to MMR pairs, whose increasing occurrence supports a smooth migration into a resonant configuration during the protoplanetary disk phase.

Abstract
We report the discovery of cometary activity in the form of a pronounced tail emanating from Near-Earth Object (523822) 2012 DG61, identified in UT 2024 April 18 Dark Energy Camera images by our AI assistant TailNet. TailNet is an AI designed to filter out images unlikely to show activity for volunteers of our NASA Partner “Active Asteroids” Citizen Science campaign, from which our AI is trained. Subsequently, our archival investigation revealed 2012 DG61 is recurrently active after we found it displaying a pronounced tail in a UT 2018 April 16 Steward Observatory Bart Bok 2.3 m telescope image and UT 2018 May 14 observations by G. Borisov with the 0.3 m telescope at MARGO Observatory. Our dynamical integrations reveal that 2012 DG61, an Apollo dynamical class member, is likely in 2:1 mean-motion resonance with Jupiter. We encourage additional observations to help characterize the activity morphology of this near-Earth comet.
Polycyclic Aromatic Hydrocarbons as an Extraterrestrial Atmospheric Technosignature
Authors: Dubey Dwaipayan , Kopparapu Ravi , Ercolano Barbara , Molaverdikhani Karan 
Published: January 2025

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are prevalent in the Universe and interstellar medium but are primarily attributed to anthropogenic sources on Earth, such as fossil fuel combustion and firewood burning. Drawing upon the idea of PAHs being suitable candidates for technosignatures, we investigate the detectability of those PAHs that have available absorption cross sections in the atmospheres of Earth-like exoplanets (orbiting G-type stars at a distance of 10 pc) with an 8 m mirror of the Habitable Worlds Observatory (HWO). Specifically, we focus on Naphthalene, Anthracene, Phenanthrene, and Pyrene. Our simulations indicate that under current-Earth-like conditions, detecting PAH signatures between 0.2 and 0.515 μm is infeasible. To account for the historical decline in PAH production post the industrial revolution, we explore varying PAH concentrations to assess instrumental capabilities of detecting civilizations resembling modern Earth. We also evaluate telescope architectures (6 m, 8 m, and 10 m mirror diameters) to put our results into the context of the future HWO mission. With these four molecules, PAH detection remains infeasible, even at concentrations 10 times higher than current levels. While larger mirrors provide some advantages, they fail to resolve the spectral signatures of these molecules with significant signal-to-noise ratios. The UV absorption features of PAHs—caused by π-orbital → π*-orbital electronic transitions—serve as valuable markers, due to their distinct and detectable nature, preserved by the aromatic stability of PAHs. Additional lab measurements are necessary to gather absorption cross-sectional data beyond UV for more abundant PAHs. This may help further in improving the detectability of these molecules.

Published: January 2025

The rectovaginal septum is a rare location for gastrointestinal stromal tumors (GIST) to occur. The aim of this study was to present a case of synchronous local recurrence of solitary liver metastasis originating from an extra gastrointestinal tumor (E-GIST) of the rectovaginal space.
A 55-year-old woman, with a medical history of a resected meningioma, was referred to our department due to a 5 cm solitary liver metastasis located within the left lateral segment. The patient had undergone a transvaginal resection of a low-risk E-GIST 6 months prior without receiving adjuvant chemotherapy. The patient underwent a synchronous laparoscopic left lateral hepatectomy and a transvaginal resection with posterior vaginal wall reconstruction. Her postoperative course was uneventful and was discharged on the fifth postoperative day. The histological examination of the vaginal lesion revealed the development of neoplasm with pathological characteristics consistent with the initial histology expect for a mitotic index exceeding &gt;20%. Liver histology report also included a high-risk GIST with CKIT (+), DOG1 (+), ki67 ≥30%, high mitotic activity and clear resection margins. The patient was referred for adjuvant chemotherapy.
E-GISTs are rare neoplasms with low malignant potential. However, these tumors may exhibit metastatic potential and require aggressive treatment.
Navigating the Unique Complexities of Dissertation Supervision in Doctoral Nursing Education
Authors: Birnbaum Shira , Zha Peijia 
Published: January 2025

Background
Complex educational challenges emerge during Doctor of Philosophy (PhD) dissertation research, yet many newly hired faculty receive little preparation for the role of dissertation supervisor. The intensity and rigor of dissertation supervision are not reflected in workload calculations based on enrollments or clock hours. New faculty have few venues beyond personal experience to learn the challenges that supervision entails.

Method
This article presents reflections of two research methodologists who supervise students in a nursing science PhD program in a large research university. It explores several challenges and dilemmas that characterize the supervision process.

Results
Challenges of supervision involve dynamics of power, authority, and reputational self-protection, which reflect the paradoxical nature of the dissertation process, the distinct structure of graduate nursing education, nonlinear trajectories of doctoral learning, and risks related to the growth of generative artificial intelligence.

Conclusion

Newly hired faculty need to be prepared for the unique challenges of supervising student research.

Droit du travail et géopolitique de l’énergie
Authors: Tomassetti Paolo 
Published: January 2025

Cet article explique pourquoi et comment différents paradigmes énergétiques et leur économie politique ont affecté les institutions de relations professionnelles et industrielles au fil du temps. S’appuyant sur une nouvelle littérature qui considère les sources d’énergie comme un référent analytique central, sont discutés et présentés les contextes économiques reposant successivement sur le charbon, le pétrole, le nucléaire et le solaire. Alors que la possibilité d’un contrôle de la main-d’œuvre sur l’extraction et la distribution du charbon a favorisé le développement d’institutions démocratiques et d’un État-providence dans les régimes occidentaux et dans les économies récemment développées de ce que l’on appelle les pays du Sud, le « pétro-capitalisme » et l’économie politique de l’énergie nucléaire ont contribué au démantèlement des marchés internes du travail et à la crise des institutions classiques du droit du travail et des relations professionnelles1. Contrairement au pétrole et au nucléaire, les énergies renouvelables pourraient favoriser le passage d’un modèle économique extractif à un modèle génératif et participatif : en introduisant plus de démocratie dans le pouvoir politique et économique de l’énergie, les énergies renouvelables pourraient mieux servir le bien-être humain, le travail et l’environnement.
Les accords CSE, échecs sur ordonnances
Authors: Paulin Jean-François 
Published: January 2025

Si la mise en place des Comités sociaux et économiques (CSE) par la voie de l’accord collectif était un objectif, les études commandées au titre de l’évaluation du dispositif montrent un double échec. Quantitatif d’abord puisque moins de 10 % des CSE installés l’ont été conventionnellement. Qualitatif enfin car le contenu des accords de mise en place et de fonctionnement des CSE sont peu innovants ; ils se contentant souvent d’une reprise des minimas légaux.
Des nains et des géants : Pascal et la question de la modernité
Authors: Gheeraert Tony 
Published: January 2025

Pascal est-il moderne ou antimoderne ? Les deux images ont longtemps cohabité, dans une dualité qui opposa volontiers la figure du scientifique et celle du théologien. En réalité, la modernité de Pascal, si généralement admise aujourd’hui, est pour une grande part le résultat d’une construction à laquelle le savant auvergnat a largement contribué lui-même dans ses travaux de physique et de mathématique : il a participé à l’élaboration précoce d’un récit épique de la modernité opposant la vérité scientifique et la raison à l’obscurantisme d’institutions sclérosées. Sur le fond, l’indécidabilité de la dialectique moderne/antimoderne invite à mobiliser d’autres catégories pour tenter de situer correctement Pascal dans l’histoire des idées.
Montaigne chez Pascal : de la citation au versionnage
Authors: Koch Erec R. 
Published: January 2025

Les études sur les « réminiscences » de Montaigne dans les Pensées de Pascal se sont concentrées sur la citation. Cet article établit qu’il est plus efficace de considérer l’utilisation de Montaigne par Pascal en termes d’une autre modalité intertextuelle : le versionnage. Tout en récoltant davantage d’exemples de recyclage textuel, le versionnage offre également une explication plus productive de la manière dont Pascal ablate et réutilise le texte de Montaigne. Enfin, le versionnage propose un modèle de la théorie et de la pratique de l’écriture dans et des Pensées, un modèle que Pascal généralise à toute écriture.
Raúl Ruiz en Italie : vers un art déterritorialisé
Authors: Monneau Boris 
Published: January 2025

Si Raúl Ruiz est essentiellement connu comme cinéaste, il est aussi l’auteur d’une œuvre littéraire vaste et en grande partie inédite. Pour aborder un pan encore méconnu de son activité artistique, qui inclut également la pratique de l’installation, nous nous centrerons sur un autre domaine largement ignoré : celui des productions italiennes de l’auteur. En effet, Ruiz, qui maîtrise fort bien la langue de Dante, a mis en scène plusieurs pièces originales en Italie, publié trois ouvrages, conçu ou projeté deux installations et réalisé une poignée de films à peu près invisibles. Ce territoire plus ou moins vierge dans le domaine de la recherche nous permet d’interroger les rapports de Ruiz à la notion de territoire, ainsi que son approche déterritorialisante des médiums artistiques.
