Published: August 2024

Abstract. We document the isotopic evolution of near-surface snow at the East Greenland Ice Core Project (EastGRIP) ice core site in northeast Greenland using a time-resolved array of 1 m deep isotope (δ18O, δD) profiles. The snow profiles were taken from May–August during the 2017–2019 summer seasons. An age–depth model was developed and applied to each profile, mitigating the impacts of stratigraphic noise on isotope signals. Significant changes in deuterium excess (d) are observed in surface snow and near-surface snow as the snow ages. Decreases in d of up to 5 ‰ occur during summer seasons after deposition during two of the three summer seasons observed. The d always experiences a 3 ‰–5 ‰ increase after aging 1 year in the snow due to a broadening of the autumn d maximum. Models of idealized scenarios coupled with prior work indicate that the summertime post-depositional changes in d (Δd) can be explained by a combination of surface sublimation, forced ventilation of the near-surface snow down to 20–30 cm, and isotope-gradient-driven diffusion throughout the column. The interannual Δd is also partly explained with isotope-gradient-driven diffusion, but other mechanisms are at work that leave a bias in the d record. Thus, d does not just carry information about source-region conditions and transport history as is commonly assumed, but also integrates local conditions into summer snow layers as the snow ages through metamorphic processes. Finally, we observe a dramatic increase in the seasonal isotope-to-temperature sensitivity, which can be explained solely by isotope-gradient-driven diffusion. Our results are dependent on the site characteristics (e.g., wind, temperature, accumulation rate, snow properties) but indicate that more process-based research is necessary to understand water isotopes as climate proxies. Recommendations for monitoring and physical modeling are given, with special attention to the d parameter.
On optimizing the sensor spacing for pressure measurements on wind turbine airfoils
Authors: Fritz Erik K. , Kelley Christopher L. , Brown Kenneth A.
Published: August 2024

Abstract. This research article presents a robust approach to optimizing the layout of pressure sensors around an airfoil. A genetic algorithm and a sequential quadratic programming algorithm are employed to derive a sensor layout best suited to represent the expected pressure distribution and, thus, the lift force. The fact that both optimization routines converge to almost identical sensor layouts suggests that an optimum exists and is reached. By comparing against a cosine-spaced sensor layout, it is demonstrated that the underlying pressure distribution can be captured more accurately with the presented layout optimization approach. Conversely, a 39 %–55 % reduction in the number of sensors compared to cosine spacing is achievable without loss in lift prediction accuracy. Given these benefits, an optimized sensor layout improves the data quality, reduces unnecessary equipment and saves cost in experimental setups. While the optimization routine is demonstrated based on the generic example of the IEA 15 MW reference wind turbine, it is suitable for a wide range of applications requiring pressure measurements around airfoils.

Significance and Institutional Improvement of Anti-Corruption Investigation in Korea's Anti-Corruption Policy System
Authors:   Korean Association For Corruption Studies, Kim Sang Nyon , Lee Jun Seo
Published: August 2024

To prevent corruption, it is important to revise related laws and regulations for anti-corruption policy system improvement. However, in order to derive results of system improvement, a fact-finding survey or investigation must be conducted first to confirm the operation status and problems of the current system. Under current Act on the Prevention of Corruption and the Establishment and Management of the Anti-Corruption and Civil Rights Commission, surveys related to corruption prevention can be broadly classified into three categories: (1) investigation and evaluation of corruption in public institutions; (2) an explanation, request for data submission and fact-finding survey to establish and recommend policies and system improvements to prevent corruption in public institutions; (3) an investigation to verify details of reports of corruption.
The fact-finding survey under Article 29 of the Act, which is the second type among the above, is a very important part of deriving institutional improvement plans to achieve anti-corruption policy results. In this paper, we conduct a theoretical review of the concept and nature of the survey used to promote institutional improvement, considering the significance of this survey in anti-corruption policies.
The fact-finding survey or investigation for anti-corruption policies and system improvement hosted by the Anti-Corruption and Civil Rights Commission can be used as an effective corruption control tool because it not only has its own ripple effect but also has a large impact on the subsequent operation of the system. However, since the purpose of the survey under this Act is different from a general fact-finding survey, there is a need to establish more detailed and predictable standards and procedures for the survey method, survey conduct, and use of survey results as provided in the Framework Act on Administrative Investigations. Considering the above factors, it is necessary to comprehensively supplement the fact-finding system, including institutionalizing each type of fact-finding survey and investigation, clarifying the detailed implementation procedures of the fact-finding survey and investigation, and establishing a relationship with the Framework Act on Administrative Investigations.

Balancing Seniority Rewards and Performance: Challenges and Solutions in Human Resource Management
Authors: Azzahra Adelia , Savandha Septien Dwi , Ridzki Mohamad Maulana , Amelia Amelia
Published: August 2024

The study examined the impact of reward and compensation systems on employee performance in medium-sized companies, focusing on workers who had been working for a long time but showed declining performance. Through a qualitative case study approach, this study identifies challenges and dynamics in the implementation of seniority and performance-based reward systems. The results show that seniority-based reward systems tend to be less effective because they give significant recognition to existing employees even though their productivity decreases, while new employees who contribute highly are less rewarded accordingly. In contrast, performance-based compensation systems have proven to be more effective in improving the motivation and retention of high-performing employees. However, the main challenge in this system is determining fair and transparent performance metrics. A hybrid approach that combines elements of seniority and performance can create a balance, but it requires special attention to fairness and consistency in its implementation. The study's main recommendations are the development of a fair and transparent reward system, continuous evaluation, and employee involvement in developing and reviewing the reward system to increase motivation and acceptance. This research makes an important contribution to a more effective and sustainable human resource management strategy.

Published: August 2024

Objective: This 2023 study aimed to assess pain relief, functional recovery, and kyphosis correction following pedicle screw surgery with cement augmentation in severe osteoporosis patients with vertebral collapse. Methods: Seventy-one patients underwent surgery and were evaluated for postoperative pain reduction (VAS score), functional improvement (ODI score), vertebral kyphosis angle, pre- and postoperative spinal curvature angles, and complications. Results: The study included 71 participants (13 males, 58 females; mean age 67.6±6.7 years). Trauma sources included falls (47.9%), heavy lifting (17%), and unclear mechanisms (35.2%). Mean hospital stay was 12±6.5 days. Preoperative, postoperative, and 1/6-month VAS scores were 8.7, 2.2, 1.5, 0.9 respectively (p<0.001). ODI scores were 77.6, 52.8, 43.0, 37.9 respectively (p<0.001). Kyphotic angle (vertebral body) decreased from preop 12.9° to postop 9.9°, 1/6 months 10.1° (p<0.001); at surgical site, preop 15.4° to 1/6 months 11.9° (p<0.001). Cement leakage occurred in 36.6% of cases, mostly asymptomatic, with distribution in the disc space (2.8%), blood vessels (8.5%), around vertebral body (12.7%), spinal canal (14.1%), and lungs (2.8%). Conclusion: Pedicle screw fixation with enhanced cement augmentation effectively manages severe osteoporotic vertebral compression fractures, providing significant pain relief, improved postoperative function, and spinal alignment. Symptomatic cement leakage is rare.

Published: August 2024

The study aimed to determine the incidence and severity of postoperative complications in early breast cancer (BC) females undergoing immediate breast reconstruction (IBR) with implant and polypropylene mesh (PPM) after nipple-sparing mastectomy (NSM). This study is a retrospective, single-arm and single-institutional trial. The population selected was females with BC treated at Ho Chi Minh City Oncology Hospital from July 01, 2022, to Jan 31, 2024. The inclusion criteria included pathology as carcinoma of breast at preoperative stage as 0, I or II with tumor less than 3cm, and being treated with NSM followed by implant-based IBR with PPM. 28 patients met the inclusion criteria. Of two patients, the former had a late infection, whereas the latter suffered from nipple-areolar necrosis, accounting for 8% of all. Both patients were well managed with medical therapy. We did not find any statistical significance between the postoperative complications and relevant clinical and therapeutic characteristics. PPM enables the cavity to hold the implant, while still maintaining natural breast appearance. This is a safe surgical procedure to perform. PPM may be considered as an alternative for covering the lower anterior aspect of implant, especially in developing countries like Vietnam.

Published: August 2024

The study aimed to evaluate the effectiveness of school- and community-based interventions in improving knowledge and practice of burns prevention for secondary school students in Vu Thu district, Thai province. We conducted a controlled community trial in the Vu Thu district, Thai Binh province. The self-administered structured questionnaire, which was developed under the instruction of experts in burn injury prevention, and the information page of the Ministry of Health and the Ministry of Education and Training, was used in this study. The effectiveness of the intervention was evaluated by comparing the effectiveness index before and after the intervention between the intervention group and the control group. Among 2028 secondary school students, the score of knowledge about burn prevention in the control group and the intervention group increased after intervention (from 6.238±2.050 to 6.847±2.033 and from 6.257±2.112 to 7.314±1.824, respectively). Knowledge scores on recognizing the causes and ways to prevent burns tend to increase after the intervention, especially in students with higher knowledge scores on these two topic groups than the control group. It is similar to the score of practice in preventing burn injuries, from 6.047±3.582 to 6.247±3.660 in the control group and from 6.638±3.411 to 7.342±3.207 in the control group. The effectiveness of the intervention has contributed to increasing secondary school students’ knowledge and practice of preventing injuries caused by burns. Therefore, it is necessary to continue research in secondary schools, especially in suburban areas and other provinces, to obtain reliable evidence for policy development and planning for injury prevention - burning injuries.

Assessing forest biodiversity is crucial for supporting sustainable forest planning. We investigated the potential for biodiversity and carbon sequestration in both artificial and natural forests of the arboretum of the National School of Water and Forests (ENEF) of Mbalmayo. A floristic inventory was carried out in 72 plots measuring 25m x 25m in the artificial forest covering an area of 4.5ha, and in a quadrat measuring 250m x 180m in the natural forest of the arboretum. Carbon stocks were determined by the non-destructive method using allometric equations. The results of the woody biodiversity inventories identified 77 species belonging to 69 genera and 33 families. This species richness varied from 69 species in the natural forest to 58 species in the artificial forest. Tree density was slightly higher in the artificial forest (616 ±339 ind/ha) than in the natural forest (312 ±176 ind/ha), without being significantly different. Basal area was constant in both types of forest studied, with an average of 55.97 ±36.28 m2/ha in the artificial forest and 58.33 ±19.42 m2/ha in the natural forest. The greatest quantity of sequestered carbon was found in the natural forest with 432±146.49 tC/ha compared with 400.69±328.37 tC/ha in the artificial forest. Nevertheless, these rates were not significantly different according to the ANOVA test. Given the importance of this massif in carbon sequestration and the needs of local populations, ENEF should support these populations in agroforestry practices and in the domestication of priority tree species.

Hacer lugar y constitución según la sublevación Lumpérica: “por la cicatriz sabía que me dolía”
Authors: Sotomayor Áurea María
Published: August 2024

A partir de nociones relacionadas con el concepto de espacio público, acción y libertad en Hannah Arendt, este ensayo analiza varias de las acciones de la protagonista y del lumperío que habitan la plaza como momentos de insubordinación (y desafío) que devienen sospechosos para el régimen. En la plaza, el “fuera de lugar” se convierte en habitar a partir del actuar de L. Iluminada quien crea una potencia de comunidad a través del grafiteo, la performance, la escritura, contrario a lo que dictamina el Estado dictatorial. Política y estéticamente, autoconstituirse y Constitución se aúnan en una propuesta de justicia social. Tanto la foto de la mujer herida insertada en el libro como el lenguaje barroco sobre el que se sostiene el texto son evidencia de una estética no representacional donde los lectores movilizan el sentido y lo comunitario. Usando conceptos de Arendt, Negri y Deleuze/Guattari respecto del espacio público, la ética y el deseo de comunidad, esta lectura de Lumpérica insiste en que aquí asistimos a la transformación del espacio ocupado por la dictadura en un espacio para la libertad estética y política.
Discurso y terror. Del lenguaje de la política a la política del lenguaje
Authors: Alarcón Luis Felipe
Published: August 2024

Durante el Gran Terror en Francia (1793-1794), la Convención Nacional liderada por los jacobinos impuso una serie de medidas tendientes a infundir miedo mediante la violencia estatal. Dada su importancia y ejemplaridad, este período se convirtió en un arquetipo de los regímenes autoritarios, en los que la legalidad queda suspendida y reina la sospecha y la arbitrariedad. De este modo, Terror pasó a significar, además de un período histórico, una forma de ejercer el poder. Ahora bien, durante el siglo XX, el interés por la relación entre política, lenguaje e ideología llevó a diversas disciplinas a volver a analizar el Gran Terror, haciendo énfasis en el lenguaje político utilizado. El siguiente artículo se propone analizar el Terror bajo una nueva perspectiva: la de las políticas del lenguaje. Para ello, se analizan las posiciones de Saint-Just y Robespierre, líderes principales del jacobinismo. Con ello se intenta abrir nuevas preguntas y comprensiones de la relación entre política y lenguaje.
La búsqueda de un Rousseau mimético
Authors: Valenzuela María de Los Andes
Published: August 2024

Este artículo analiza el pensamiento de Jean-Jacques Rousseau (1712-1778) a partir de la teoría mimética propuesta por el filósofo, crítico literario e historiador francés René Girard (1923-2015). En tal sentido, cabe sostener que la obra de Rousseau, con especial notoriedad su antropología del amor de sí, presente entre otras obras, en Discurso sobre el origen de la desigualdad entre los hombres (1755), encierra una particular obsesión y temor al mimetismo y sus violentas consecuencias.
Integrating Multifunctional Street Design Concepts: A Case Study of Kayışdağı Street
Authors: İnan Zerrin , Carlık Orçun Mert
Published: August 2024

Streets are a network of social, economic, and physical activities that contribute to the vitality of neighborhoods. Successful urban streets have multiple functions beyond simply moving people and goods from place to place. At least 20-30% of cities are made up of streets, a huge infrastructure that needs to be maintained and developed. They have the potential to help address today's urban challenges related to climate change, biodiversity loss, health problems, and well-being. Different street design strategies are presented as a response to these challenges, as they can fulfill this multitude of functions; they are not only transport infrastructures, but also lively and inclusive public spaces, carriers of economic development, ecological corridors supporting ecosystem services, and lines of technical infrastructure including street and traffic lighting, electrical power, signalization, etc. Complete Streets, Green Streets, Healthy Streets, and Place Making and Streets are all concepts and initiatives that have evolved to address issues related to the planning and design of street environments, each with its own focus and definitions. This article introduces the current approaches to street design and proposes to integrate principles from each of the four concepts into Kayışdağı Street in Istanbul. It is selected as a case study to improve existing university districts' services and build new neighborhoods as the population grows exponentially.
La cultura material y la construcción de identidad de género en el siglo XIX en el contexto escolar (Santiago, Chile)
Authors: Gana Katherine
Published: August 2024

Se presenta una investigación histórica acerca de la construcción de la identidad de género durante el siglo XIX en el contexto educacional chileno, mediante la creación de una muestra de estudio obtenida de objetos del sitio arqueológico Pique Hospitales, y elementos seleccionados del Museo de la Educación Gabriela Mistral y del Museo Histórico Nacional. La muestra, el análisis físico y los antecedentes históricos permitirán normar el material para conocer cuáles son los aspectos físicos y simbólicos relevantes al momento de la clasificación de cada uno de estos objetos en categorías de género, comprendiendo de esta forma el vínculo objeto-sujeto. Para cumplir con los objetivos planteados en la investigación se utilizaron metodologías y referencias teóricas respectivas a la arqueología histórica y de corte de género, que permiten reflexionar en torno a la construcción de roles sociales históricamente establecidos y su implicancia en el vínculo con la materialidad.

Silencios, soporopos y otras estrategias para evadir la censura en dictadura
Authors: Rebolledo Loreto
Published: August 2024

El 11 de septiembre de 1973, en la mañana, las radios de los partidos políticos de la Unidad Popular o identificadas como de izquierda fueron silenciadas. En algunos casos, bombardearon las antenas. En otros, se detuvo a radiocontroladores y periodistas. Fue el primer indicio de que la censura sería compañía frecuente durante los años de dictadura y que la voluntad de acallar cualquier voz o mensaje que sonara a disidencia respecto a la ideología del régimen sería perseguida, así como toda información que pretendiera dar cuenta de las violaciones a los derechos humanos en marcha.
En torno a diferentes usos de la nada: m´ístico, filosófico y político
Authors: Becker-Lorca Martin Stephan
Published: August 2024

Este artículo describe tres usos del concepto de la nada. Primero, en el ámbito de la mística cristiana, analizamos el tratamiento que de esta categoría hace el monje dominico del siglo XIII Meister Eckhart; luego, dentro del ámbito filosófico-político, revisamos los usos que de esta noción hacen el filósofo de la liberación argentino Enrique Dussel y el poeta y teórico cultural norteamericano Fred Moten. Nuestra intención es investigar posibles influencias del empleo de la nada en la mística cristiana sobre el ámbito filosófico-político. Postulamos que en los tres casos se da una dinámica de la nada que concluye con una inversión, en la cual se pasa desde la experiencia de la nada como defecto o privación hacia la nada como exceso, es decir, de lo sub-ontológico a lo trans-ontológico. Consideramos que estos tres usos de la nada están en función del rédito que esta inversión posibilita.
Datificación Social e Inteligencia Artificial: ¿hacia un nuevo “salto de escala”?
Authors: Gendler Martín
Published: August 2024

Desde la década de 1970 se asiste a un proceso de fuerte penetración de las tecnologías digitales en todos los ámbitos de la vida. Actualmente, su proceso de masificación y concretización ha permitido entrever una nueva fase del informacionalismo, íntimamente vinculado con el desarrollo de las tecnologías 4.0, donde el avance de la datificación social se presenta como un factor fundamental.
El presente artículo busca analizar los desarrollos actuales de Inteligencia Artificial dentro de las lógicas del proceso de datificación social, entendiéndolos como un elemento clave tanto para potenciar el mismo, como también abriendo la puerta a pensar un nuevo “salto de escala” en los actuales procesos de personalización y modulación algorítmica.
Para ello se despliega una breve genealogía de los procesos de datificación social en conjunto con un análisis de las distintas fases del desarrollo de IA hasta el momento para ahondar en su entendimiento, características y efectos sociotécnicos.

Estudio diagnóstico de habilidades de preparatividad académica de estudiantes pertenecientes al programa de acceso a la educación superior (PACE)
Authors: Durán Millavil Maximiliam , Rossel Órdenes Alejandro , Vera Benavides Rodrigo
Published: August 2024

El abandono y la permanencia en la educación superior es relevante en las investigaciones actuales y ha implicado una búsqueda de factores o variables que influyen en este fenómeno. Uno de ellos es la preparatividad académica, entendida como las habilidades previas desarrolladas durante la educación escolar y que son la base para enfrentar los estresores propios de la vida universitaria. El desarrollo de estas habilidades en la educación media no siempre es adecuado o logrado, lo que impacta en el rendimiento y permanencia en la universidad. El objetivo del estudio fue determinar los perfiles de ingreso asociados a la preparatividad académica de estudiantes pertenecientes al Programa de Acceso a la Educación Superior (PACE). Mediante la aplicación de un instrumento a una muestra de 167 estudiantes con ingreso vía PACE, se determinaron perfiles de preparatividad académica que evidencian que el estudiantado se caracteriza por las dimensiones de Autodeterminación Personal y Autoeficacia Académica con altas puntuaciones promedio, en tanto que las dimensiones más descendidas fueron Modulación emocional y Comunicación efectiva. Estos resultados permiten generar estrategias de acompañamiento y sistemas preventivos de monitoreo para apoyar los procesos de adaptabilidad a la educación superior de estudiantes provenientes de sectores con alta vulnerabilidad social.

L'ottica metonimica nel racconto “Il padre di Bucarest” di Ivan Stankov
Authors: Nyagolova Natalia
Published: August 2024

L‘articolo esamina il meccanismo metonimico come tratto distintivo della prosa bulgara moderna attraverso osservazioni sul racconto di Ivan Stankov „Il padre di Bucarest“ tratto dal libro “Nomi sotto la neve” (2019). Il racconto rompe il quadro tradizionale del “testo rumeno” nella letteratura bulgara, solitamente strettamente legato alle trame iniziatiche delle lotte di liberazione nazionale e alla prosa militare della prima metà del XX secolo. Nell‘opera Bucarest conserva le sue caratteristiche nazionali solo nel piano della topografia letteraria. Allo stesso tempo, la Bucarest di I. Stankov acquisisce le caratteristiche di qualsiasi grande città metropolitana del mondo, dove regna l‘alienazione, mentre l‘empatia è un impulso raro e inaspettato. L‘ottica metonimica viene esplorata a diversi livelli: come principio di immagine dello spazio urbano; come concetto stilistico di combinazione di immagini eterogenee; come meccanismo di intertesto; come asse paradossale del pensiero e dell‘esistenza dell‘uomo moderno, creato attraverso la traduzione di informazioni non selezionate, attraverso l‘illusione dinamica emotiva e sociale del mondo globale.
