The production study of Auger emitters in platinum group metal for radiotherapy
Authors: Ohya Tomoyuki
Published: November 2024

Targeted radioisotope therapy (TRT) is a type of internal radiotherapy that combines radiation therapy and targeted therapy to eliminate cancer cells without damaging healthy tissue. Radionuclides attached to targeting molecules travel to cancer cells and emit radiation in the form
of beta-ray emitting nuclides and alpha nuclides. A third type of nuclide called Auger emitter can be used in a treatment called Auger therapy. Dr Tomoyuki Ohya, Department of Advanced Nuclear Medicine Sciences, Institute for Quantum Medical Sciences (iQMS), National Institutes for Quantum
Science and Technology (QST), Japan, is interested in Auger therapy as a radiotherapy that only affects the tissues that require treatment. Challenges associated with this treatment are the short range of Auger electrons, meaning that they must be precisely targeted in order to be effective.
With a view to overcoming this, Ohya is focusing on Pd-103 and Rh-103m as optimal nuclides for Auger therapy. He is working to develop a technology to facilitate high-quality, large-scale manufacturing that can be applied to the clinical use of Auger therapy, enhancing its efficiency and rendering
its use on a wide scale possible. In one project, Ohya investigated the potential of developing an efficient and reliable method for producing Rh-103m. Due to its short half-life it needs to be produced by a generator for clinical use. As the anion-exchange resins used in previously developed
generators are no longer commercially available, Ohya and the team prepared and tested generators using commercially available anion-exchange resins.
Research to reduce pain and increase comfort using skin cleaning materials
Authors: Shimizu Hiroko
Published: November 2024

During her nursing career, Professor Emeritus Hiroko Shimizu focused on the need for nursing care to promote and support patient recovery and found that the use of steam cloths helped relax patients and reduce their physical and mental pain. Shimizu is affiliated with Kagawa University
and has been working to investigate the impact of skin cleaning materials on the brain waves of patients. Shimizu and her collaborators set out to create something that could warm people affected by disasters and relieve the pain of cancer patients. The researchers were the first to employ
a method invented by Professor Ichirou Ishimaru to measure moisture using near-infrared two-dimensional Fourier spectrometry. They measured moisture smearing on the skin and found a softening and smoothing effect on the skin. This led them to develop a steam-generating cleaning tool that induces
relaxation without a towel or cloth. Part of Shimizu’s work concentrates on developing new techniques and measurement methods needed to verify her findings. The researchers also used text analysis of the subjects’ statements and psychological images to project their thoughts and
attitudes towards the care provided, as well as an electroencephalogram analysis by a neurologist, Visiting Professor Tetsuo Toge, to correlate the results. Shimizu plans to incorporate an analysis of steam volume and moisture or images with temperature and humidity into her considerations.
In one study, Professor Hidekuni Takao, who shared Professor Shimizu's research, is working as the representative of a Japan Science and Technology Agency (JST)-CREST project to develop a rare device to measure the shape of the skin surface. The goal is that the integrated semiconductor tactile
sensor the researchers are developing will have equal or even greater sensitivity and performance than that of a human fingerprint.
Supine Sleep-Promoting Baby Mattress: SIDS Prevention and Athlete Injury Relief
Authors: Chen Shing-Jye , Lin Cheng-Feng Connie
Published: November 2024

Sudden Infant Death Syndrome (SIDS) is a leading cause of death in infants aged one to 12 months, primarily occurring during sleep. Consequently, there is considerable interest among researchers and healthcare professionals regarding the sleeping environment and potential risk factors.
One identified risk factor is infants sleeping prone (on their stomach), making supine (on the back) sleeping the recommended position. Associate Research Fellow Shing-Jye Chen from the Department of Sports Science Research at the Taiwan Institute of Sports Science (TISS) is developing a hammock-like
air-based baby mattress covered with breathable mesh. This mattress is designed to promote supine sleeping and prevent babies from rolling onto their stomachs during sleep. It features air tubing within tensioned mesh fabric that automatically adjusts to suspend and support the baby’s
weight. This design increases the contact surface area between the baby and the mattress, reduces contact pressure, and provides evenly distributed support as the baby grows. Chen takes an interdisciplinary approach, collaborating with experts in baby breathing, sleeping patterns, and biomechanics
to develop solutions aimed at reducing the risk of SIDS based on scientific evidence, safety, and effectiveness. In a pilot study, Chen collected data on the mattress’s performance using weights to simulate babies of different ages. His team will explore the relationship between weight
and the measured pressure values at different internal air pressures within the inflatable tubing design. The potential application of this product design may extend to injured athletes, particularly in areas where injuries contact the mattress surface, thereby reducing stress.

This study aimed to clarify the effect of capital structure on earnings volatility and cash flows in the commercial banking sector. The research focused on all 15 banks listed on the Amman Stock Exchange, and data were gathered from their financial statements between 2018 and 2022. The study employed multiple regression analysis to assess the data and test hypotheses. Previous studies have shown mixed results, with some finding a positive relationship between capital structure and financial performance, while others presented opposing views. The findings of this study provide statistical evidence that the debt-to-asset ratio (DTA) positively influenced operating cash flows and their volatility, while negatively affecting profits and their volatility. Additionally, the debt-to-equity ratio (DETE) positively impacted operating cash flows, their volatility, and profit volatility. These results suggest that banks should aim for a balanced capital structure to maintain stable profits and cash flows over time. This requires careful consideration of risks, regulatory requirements, market conditions, and the cost of capital. A balanced approach, involving both debt and equity financing, helps banks manage the risks of fluctuating cash flows and profits.

Authors: Johari Nor Haliza , Anwar Rusmadiah , Awang Nor Nazida , Yang Liu
Published: November 2024

Human interaction intensively impacts design in product manufacturing through design thinking, interpreted product recognition and perceptual product experience (PPE). While the dominant digitalization and artificial intelligence in generative design present significant opportunities for innovation and optimization, there is a gap in adopting holistic, human-centered approaches. Despite numerous advancements, these methods, including design thinking, are not widely practiced, and there is limited discussion on effective design methodologies. This research aims to address this issue by investigating the influence of human interaction on design processes, integrating socio-technical principles, and analyzing how product form affects user perception and recognition.

Background/Aim: There is little evidence regarding the predictive value of prostate-specific antigen (PSA) kinetics in patients with castration-resistant prostate cancer treated with an androgen receptor signaling inhibitor. This study investigated the correlation between PSA kinetics and prognosis in patients with castration-resistant prostate cancer treated with enzalutamide. Patients and Methods: We analyzed data from 103 patients who received enzalutamide as primary treatment for castration-resistant prostate cancer at our hospital, focusing on the associations between overall survival and PSA kinetics variables, such as maximal PSA response, PSA nadir, and time to PSA nadir. Results: The median PSA level at the initiation of enzalutamide was 18.1 ng/ml (interquartile range=7.9-61.2 ng/ml). The median maximal PSA response rate was 88% (interquartile range 55-98), and the median PSA nadir was 1.84 (interquartile range (IQR)=0.38-14.7) ng/ml. The median time to PSA nadir was 19 (IQR=6-28.5) weeks. Maximal PSA response rate <90% [hazard ratio (HR)=2.28, 95% confidence interval (CI)=1.03-5.03, p=0.0413], PSA nadir >2 ng/ml (HR=2.30, 95%CI=1.05-5.07, p=0.0379), time to nadir <19 weeks (HR=2.48, 95%CI=1.15-5.35, p=0.0204) were all independently predictive of shortened overall survival even after adjusting for pre-treatment factors. Conclusion: Maximal PSA response, PSA nadir, and time to PSA nadir correlated with survival in patients with castration-resistant prostate cancer receiving enzalutamide as a first-line therapy.

Background/Aim: In prostate cancer, robotic total prostatectomy is a popular treatment modality. However, prostate-specific antigen (PSA) recurrence after prostate cancer surgery remains a concern. Salvage radiotherapy is commonly used to treat PSA recurrence, but the recurrence rate after salvage radiotherapy is high, highlighting the need for better predictive markers. This study aimed to retrospectively evaluate the association between cribriform pattern and PSA recurrence in patients receiving radiotherapy after radical prostatectomy. Patients and Methods: Data of 50 patients who underwent radiotherapy after total prostatectomy between January 2010 and May 2020 were retrospectively evaluated. The median age was 67 years. Among these patients, two cases involved postoperative irradiation, while 48 cases involved salvage irradiation after postoperative PSA recurrence. The median time from surgery to PSA recurrence was 38.3 months. The median radiation dose was 64 Gy in 32 fractions. Three-dimensional conformal radiation therapy was administered in 38 cases and intensity-modulated radiation therapy was used in 12 cases. Combined hormone therapy was administered in 21 cases. PSA levels were measured every 3 months after treatment. Statistical analysis between groups was performed by a t-test. Results: The median follow-up period after radiotherapy was 31 months. No local recurrences were observed at the prostate bed, and no deaths related to prostate cancer were recorded during follow-up. However, 18 patients (36.0%) had PSA recurrence. The PSA recurrence rate based on the cribriform pattern was 17.6% in the none to moderate group (34 patients) and 75.0% in the severe cribriform pattern group (16 patients). The PSA recurrence rate was significantly higher in patients with a severe invasive cribriform pattern (p=0.001). No significant differences were observed in other histopathological characteristics. Conclusion: The cribriform pattern in surgical pathology specimens was found to be a useful predictor of PSA recurrence after postoperative radiotherapy.

Published: November 2024

Background/Aim: Owing to underlying diseases and decreased physiological functions, frailty in elderly patients may be associated with adverse postoperative complications and mortality. To date, there are various frailty assessment methods, with the five-item modified frailty index (mFI-5) being an objective and concise evaluation tool. This study aimed to clarify whether mFI-5 scoring, a measure of frailty, can predict postoperative outcomes in elderly patients undergoing laparoscopic colorectal surgery. Patients and Methods: A total of 107 patients aged over 80 years who underwent laparoscopic colorectal surgery at Nagasaki University Hospital between 2011 and 2018 were included in this study. The mFI-5 was used to assess the preoperative condition of each patient, with scores compared against various postoperative outcome measures. Univariate analysis was used to determine between-group differences for pre- and post-operative variables. Results: Of the 107 patients [median age, 83 (80-99) years], 44.9% were male. The mFI-5 score was calculated and patients were divided into three groups: 0 (n=36, 33.6%); 1 (n=44, 41.1%); and 2+ (n=27, 25.3%). The groups were significantly associated with the American Society of Anesthesiology (ASA) classification (p<0.001). Postoperative complications occurred in 43 patients (40.2%), and a higher mFI-5 score was significantly associated with postoperative complications of Clavien–Dindo grade ≥III and duration of hospital stay. Conclusion: The mFI-5 is an objective and useful tool for predicting postoperative complications of laparoscopic surgery in elderly patients with colorectal cancer.
Desmoplastic Fibroblastoma (Collagenous Fibroma) of the Knee: A Case Report and Literature Review
Authors: SHINOHARA YUKI , CHIJIIWA YOSHIRO , NISHIO JUN
Published: November 2024

Background/Aim: Desmoplastic fibroblastoma, also known as collagenous fibroma, is a rare benign mesenchymal neoplasm that primarily arises in the subcutaneous tissue of upper extremities and limb girdles. The knee is an uncommon location for desmoplastic fibroblastoma. Recent studies have demonstrated the presence of immunoreactivity for FOS like 1 (FOSL1) and rearrangements of FOSL1. Case Report: A 70-year-old woman presented with a 1-year history of a palpable mass in the medial aspect of the right knee. Physical examination revealed a 4-cm, elastic hard, mobile, nontender mass. Magnetic resonance imaging (MRI) showed a well-defined mass with prominent low signal intensity on all pulse sequences. Contrast-enhanced MRI demonstrated mild internal enhancement with rim enhancement. After an open biopsy, the lesion was successfully treated by complete excision. Histologically, the tumor was composed of bland spindle or stellate-shaped cells embedded in an abundant collagenous stroma. Immunohistochemically, the tumor cells showed diffuse nuclear positivity for FOSL1. These findings were consistent with a diagnosis of desmoplastic fibroblastoma. The patient was asymptomatic and there was no evidence of local recurrence eight months after surgery. Conclusion: Desmoplastic fibroblastoma is a distinctive benign soft-tissue tumor with FOSL1 immunoreactivity and should be clearly distinguished from more biologically aggressive mesenchymal neoplasms.
The Application of Preventive Medicine in the Future Digital Health Era
Authors: De la Torre Katherine , Min Sukhong , Lee Hyobin , Kang Daehee
Published: November 2024

A number of seismic shifts are expected to reshape the future of medicine. The global population is rapidly aging, significantly impacting the global disease burden. Medicine is undergoing a paradigm shift, defining and diagnosing diseases at earlier stages and shifting the health care focus from treating diseases to preventing them. The application and purview of digital medicine are expected to broaden significantly. Furthermore, the COVID-19 pandemic has further accelerated the shift toward predictive, preventive, personalized, and participatory (P4) medicine, and has identified health care accessibility, affordability, and patient empowerment as core values in the future digital health era. This “left shift” toward preventive care is anticipated to redefine health care, emphasizing health promotion over disease treatment. In the future, the traditional triad of preventive medicine—primary, secondary, and tertiary prevention—will be realized with technologies such as genomics, artificial intelligence, bioengineering and wearable devices, and telemedicine. Breast cancer and diabetes serve as case studies to demonstrate how these technologies such as personalized risk assessment, artificial intelligence–assisted and app-based technologies, have been developed and commercialized to provide personalized preventive care, identifying those at a higher risk and providing instructions and interventions for healthier lifestyles and improved quality of life. Overall, preventive medicine and the use of advanced technology will hold great potential for improving health care outcomes in the future.

Authors: Borrowman Jaclyn D , Carr Lucas J , Pierce Gary L , Story William T , Gibbs Bethany Barone , Whitaker Kara M
Published: November 2024

Background

Cardiovascular disease (CVD) is the leading cause of death among women in America. Hypertensive disorders of pregnancy (HDP) negatively impact acute and long-term cardiovascular health, with approximately 16% of all pregnancies affected. With CVD 2‐4 times more likely after HDP compared to normotensive pregnancies, effective interventions to promote cardiovascular health are imperative.

Objective

With postpartum physical activity (PA) interventions after HDP as an underexplored preventative strategy, we aimed in this study to assess (1) the feasibility and acceptability of a remotely delivered PA intervention for individuals with HDP 3‐6 months postpartum and (2) changes in average steps per day, skills related to PA behavior, and postpartum blood pressure (BP).

Methods

A remotely delivered 14-week health coaching intervention was designed based on prior formative work. The health coaching intervention called the Hypertensive Disorders of Pregnancy Postpartum Exercise (HyPE) intervention was tested for feasibility and acceptability with a single-arm proof-of-concept study design. A total of 19 women who were 3‐6 months postpartum HDP; currently inactive; 18 years of age or older; resided in Iowa; and without diabetes, kidney disease, and CVD were enrolled. Feasibility was assessed by the number of sessions attended and acceptability by self-reported satisfaction with the program. Changes in steps achieved per day were measured with an activPAL4 micro, PA behavior skills via validated surveys online, and BP was assessed remotely with a research-grade Omron Series 5 (Omron Corporation) BP monitor.

Results

Participants at enrollment were on average 30.3 years of age, 4.1 months postpartum, self-identified as non-Hispanic White (14/17, 82%), in a committed relationship (16/17, 94%), and had a bachelor’s degree (9/17, 53%). A total of 140 of 152 possible health coaching sessions were attended by those who started the intervention (n=19, 92%). Intervention completers (n=17) indicated they were satisfied with the program (n=17, 100%) and would recommend it to others (n=17, 100%). No significant changes in activPAL measured steps were observed from pre- to posttesting (mean 138.40, SD 129.40 steps/day; P=.75). Significant improvements were observed in PA behavior skills including planning (mean 5.35, SD 4.97 vs mean 15.06, SD 3.09; P<.001) and monitoring of PA levels (mean 7.29, SD 3.44 vs mean 13.00, SD 2.45; P<.001). No significant decreases were observed for systolic (mean –1.28, SD 3.59 mm Hg; Hedges g=–0.26; P=.16) and diastolic BP (mean –1.80, SD 5.03 mm Hg; Hedges g=–0.44; P=.12).

Conclusions

While PA behaviors did not change, the intervention was found to be feasible and acceptable among this sample of at-risk women. After additional refinement, the intervention should be retested among a larger, more diverse, and less physically active sample.
Game-Based CBT with Artificial Intelligence: A Method for Correcting Cognitive Distortions by Revisiting the Past (Preprint)
Authors: Kim Jaehyun , Oh Hayoung
Published: November 2024

UNSTRUCTURED

Given that the most used therapies in psychiatry, Cognitive Behavioral Therapy (CBT) and Mindfulness-Based Cognitive Therapy (MBCT), were developed to treat depression, a new approach is needed for disorders such as Internet Gaming Disorder and Gambling Disorder, where the issue lies not in negative emotions themselves but in their expression through problematic behaviors. These behaviors act as the patient’s form of “self-prescription” to relieve stress, making it essential to propose alternative coping strategies that can effectively alleviate negative emotions. This paper proposes a novel game-based digital therapy method that reflects each patient’s individual “automatic thoughts,” based on an emotional theory expanded into a four-dimensional cognitive concept that incorporates both the feedback from coping strategies and the subjective interpretation of that feedback. An LLM agent based on a large language model and a doctor agent based on rule-based machine learning work complementarily, enabling the patient to safely and repeatedly practice active coping strategies in crisis situations.

Eliot’s Remains; An Enquiry into the Architectural ruins in The Waste Land
Authors: Singh Pooja
Published: November 2024

The research paper aims to examine the architectural ruins presented in the poem, The Waste Land by T.S Eliot. The scope of architecture and its destruction in the poem builds itself on the theoretical framework of Heterotopia given by Michel Foucault where the spatial structures and normative forms are challenged using figurative language. By advancing and applying Hauntology theory given by Jacques Derrida, it informs about Eliot’s created spaces that haunt of historical past and cultural myths which furthers the poem’s nuance. To reveal dislocated modernist spaces, the paper critiques on cultural collective memory, historical trauma and acknowledges how fragmented identities, memories, moral and spiritual failure places itself in the poem through physical destruction of architecture.

Authors: Hamzah Loai Mohammed , Ibrahim Mohammed
Published: November 2024

This study, conducted at the Lath House of Agriculture College, Al-Qasim Green University during the 2021-2022 growth season, aimed to evaluate the effects of KHARZA nanoparticles (NPs) and organic fertilizer (Nutirgreen) on sour orange seedlings. Different concentrations of KHARZA NPs (0, 1, 2, and 3 g L-1) and organic fertilizer (0, 1.5, 3, and 4.5 ml L-1) were applied. The experimental design followed a randomized complete block design (RCBD) with two factors, each having four treatments, and each treatment replicated thrice. Our findings reveal that spraying KHARZA NPs at a concentration of 3 g.L-1 significantly enhanced various vegetative parameters, such as plant height, stem diameter, leaf number, and leaf area, alongside improvements in chemical properties such as mineral concentration, chlorophyll content, and carbohydrate levels in leaves. Similarly, applying organic fertilizer at a rate of 4.5 ml L-1 led to notable enhancements in both vegetative and chemical characteristics compared to the control group. Notably, combined application of KHARZA NPs at 3 g L-1 and organic fertilizer at 4.5 ml L-1 resulted in synergistic effects, yielding the most favorable outcomes in terms of vegetative growth and chemical properties. These results underscore the potential of utilizing KHARZA nanoparticles and organic fertilizers in enhancing the growth and physiological properties of sour orange seedlings, offering promising avenues for sustainable agricultural practices.

Human Resource Management Practices in Agricultural Development; the Role of Leadership, Motivation and Work Engagement
Authors: Muskarim Muskarim , Samdin Samdin , Aliddin Laode Asfahyadin
Published: November 2024

Development is the government's performance goal. Experts agree that agricultural development is the key to a nation's progress. At the same time, development must be supported by human resource capabilities. This research investigates human resource management practices in certain agricultural development activities. Two main objectives will be presented in this research. The first is an analysis to present new facts regarding HRM practices in the agricultural sector, including topics that are the focus of expert discussion on HRM variables such as leadership, motivation, and work engagement in reflecting performance. Second, presenting facts regarding management aspects of several variables discussed in management practice, namely the role of leadership, motivation, and work engagement on performance. This research uses a systematic review of 29 journals on HRM in agricultural development and 36 journals on the performance of non-agricultural organizations. There are several techniques used to get these numbers; (1) Journals are limited to topics that match the research topic with the search keyword "human resource management practices in the agricultural sector"; (2) To meet data quality, the journal prioritizes indexed and reputable publications (Scopus); and (3) Limiting the publication year to 2014-2024. Specifically search for journals related to HRM practices with the keywords "work engagement, leadership, and work motivation on performance". The results of the analysis then produce major themes which are then reconstructed into a road map for further research, as well as representing the scientific contribution (novelty) of the research. The results of the analysis show that human resource management practices in the agricultural sector are focused on ten topics that are widely discussed, namely: HR Management in General; Sustainable Agriculture; Empowerment and Welfare; Agro-industry; Department/Personnel; Digital Agriculture; Agribusiness; food security; Entrepreneurship; and Farm. The resulting theoretical implication is that HRM practices are starting to shift to practical development fields such as agriculture. HRM can answer several management problems in companies and the agricultural industry, such as leadership behavior and work engagement. To contribute to knowledge, the work involvement variable is a control variable in reflecting the relationship between leadership and performance; and performance motivation. For originality, the object of study can be a case in the agricultural sector. The practical implication is that the government and agricultural business actors must jointly look at problems at the worker level to increase productivity. Several behaviors hinder progress in the agricultural sector, such as low motivation and low levels of cooperation (which causes low work engagement). These things then need to be improved in the future so that organizations and companies become more productive.

En el afloramiento conocido como Cerro de los Caracoles, localizado al sur del municipio General Bravo en la Cuenca de Burgos, estado de Nuevo León, se recolectaron 132 ejemplares de gasterópodos marinos que representan los siguientes géneros: Athleta¸  Architectonica, Latirus, Distorsio, Bernaya y Turritella. Los ejemplares muestran diferentes grados de preservación, aunque todos proceden de las capas de caliza arenosa y lutita calcárea que identifican esta zona y que han sido interpretadas como sustrato duro o hardgrounds, y que posteriormente fueron separados de la matriz y depositados en sedimentos recientes. Las características litológicas así como su composición faunística indican que el afloramiento se encuentra en la cima de la Formación Cook Mountain (Eoceno). Se ha estimado una edad de 40 Ma para dicha formación, misma que coincide con el fin de los efectos de la Orogenia Laramide en la Cuenca de Burgos. Por consiguiente, se puede postular que este afloramiento podría ser representativo de uno de los primeros periodos con ausencia de sedimentación siliciclástica por acción tectónica en la cuenca.

La Cuenca de Burgos en el noreste de México tiene escasa información geológica publicada. Datos de superficie se conocen por publicaciones diversas esporádicas y cartas geológico-mineras a escalas 1:250,000 y 50,000 elaboradas por el Servicio Geológico Mexicano, los afloramientos en esta región son dispersos y su dimensión es limitada. La información de subsuelo es restringida y se conoce por aportes que Petróleos Mexicanos ha permitido divulgar. La estratigrafía, modelos sedimentarios y estructurales de esta cuenca, son extrapolados de Texas, o bien, son pocos los estudios estratigráficos y sedimentológicos que sirven como referencia análoga para inferir modelos de sedimentación aplicables a la exploración de carbón, uranio, acuíferos y yacimientos de gas en el subsuelo o con fines académicos. Por primera vez en la Cuenca de Burgos se utilizan isótopos 87Sr/86Sr para obtener una edad geocronológica de 36.75 (+2.65/-2.05) Ma, para la Formación Jackson inferior. Este intervalo estratigráfico tiene el ostréido Crassostrea cf. alabamiensis reportado por primera vez en esta cuenca; a partir de la concha bien preservada de este molusco, se obtuvo la muestra para los análisis de Sr. Los datos estratigráficos y paleontológicos de la sección estudiada sugieren interpretar una sucesión de subambientes de barra, laguna y planicie fluvio-lacustre para una costa litoral, dominada por olas y mareas, en un episodio transgresivo (transgressive system tract), cuya edad se incluye en el piso Priaboniano (Eoceno Superior).
¿Qué sabemos sobre la legislación de los fósiles en México?, un análisis preliminar

El territorio mexicano, es rico en restos fósiles tanto de flora como de fauna, los cuales son de gran interés científico, económico y social, para investigadores nacionales y extranjeros. Hasta el siglo XIX la recuperación de los fósiles siempre estuvo vinculada a la búsqueda de minerales y energéticos, pero durante el siglo XX esta actividad ha estado ligada con la academia. A pesar de que la paleontología en México se empezó a desarrollar el siglo pasado, las leyes y reglamentos que respaldan la protección y conservación del denominado patrimonio paleontológico aún presentan inconsistencias jurídicas. Actualmente, la ley establece una equivalencia entre un bien paleontológico y un bien arqueológico, homología que es inaceptable en la comunidad científica (nacional e internacional). Los fósiles se forman por procesos naturales, por lo que éstos deben formar parte del “patrimonio natural”, y la pérdida de estos materiales se debería incorporar al término conocido como “pérdida de la geodiversidad”. Uno de los factores principales que propician esta situación, es la falta de un marco legal que favorezca y rija el trabajo de los paleontólogos y otros interesados, con el fin de conservar y proteger estos bienes. Para este trabajo, se realizó una encuesta a la comunidad académica (estudiantes y profesores-investigadores) durante el XVI Congreso Nacional de Paleontología (2019) y se revisó el marco jurídico vigente relacionado con la protección y conservación de los restos fósiles; todo ello con el fin de recomendar cambios conceptuales y funcionales a la ley federal, además de considerar metodologías de trabajo para la evaluación de las colecciones y de los sitios de interés paleontológicos. Asimismo, de tomar en cuenta los criterios científicos, socioculturales y socioeconómicos, con el fin de construir un marco jurídico integral que apoye la investigación, la conservación y la protección del patrimonio paleontológico.

Se describe el gasterópodo del Ordovícico Ulrichospira Donald de una secuencia estratigráfica expuesta en el área del Rancho Las Norias en el centro de Sonora, México. El presente trabajo constituye el primer registro del género para México, el cual se encuentra asociado con una abundante fauna constituida por briozoarios, braquiópodos, gasterópodos y trilobites. La asociación de gasterópodos del Ordovícico de la formación Las Norias muestra una marcada afinidad con el cratón de Norteamérica, incluyendo los Estados Unidos de América y Canadá.

El estudio de los invertebrados marinos fósiles de México ha colaborado ampliamente al conocimiento de la historia geológica del país, al ser algunos de ellos importantes indicadores paleoambientales, paleogeográficos y geocronológicos (fósiles índice) para diferentes periodos geológicos. En este sentido, México cuenta con un registro fósil de invertebrados marinos muy diverso; sin embargo, persiste cierta escasez de conocimiento sobre las correctas prácticas y procedimientos para su extracción y colecta, lo cual ha contribuido a la destrucción total o parcial del material fósil y, por consiguiente, a la pérdida de información potencial que este material brinda. Al ser parte del patrimonio geológico del país, se debe procurar la protección, conservación y gestión de este registro fósil, por lo que compartir el conocimiento sobre su correcto manejo contribuirá a conservar de mejor manera este material y a evitar su extracción desmedida. En este trabajo se describen, por experiencias de trabajo de campo, los prprocedimientos a seguir para la extracción, colecta, etiquetado, almacenaje y trasporte de diferentes grupos de invertebrados marinos fósiles de México, incluyendo moluscos (p.e. bivalvos, rudistas, gasterópodos, ammonoideos, nautiloideos), braquiópodos, artrópodos (p.e. decápodos, ostrácodos) y equinodermos (p.e. crinoideos, equinoideos). Estos procedimientos pueden variar en función de factores como el grupo fósil, su grado y tipo de preservación, la roca portadora y la estructura anatómica preservada, entre otros. De acuerdo al grupo fósil que se estudie será la información que se pueda obtener, de tal manera que los bivalvos, rudistas, gasterópodos, ammonoideos, braquiópodos y equinoideos son considerados importantes fósiles índice en intervalos de tiempo particulares. Por otro lado, los organismos bentónicos como bivalvos, gasterópodos, rudistas, braquiópodos, crustáceos, crinoideos y equinoideos resultan adecuados para obtener información relacionada con los paleoambientes de depósito y su paleoecología. Finalmente, en cuanto a la información paleobiogeográfica, cada grupo tendrá una relevancia particular, pues tienen diferentes alcances a nivel local, regional o global.
Secured Folder Encryption and Decryption
Authors: VS Barath
Published: November 2024

In today's digital world, when sensitive data is routinely targeted by thieves, strong encryption technologies are critical for preventing breaches and ransomware attacks. Our research solves this need by creating a Secure Folder Encryption System that employs AES-GCM (Advanced Encryption Standard - Galois/Counter Mode) and HMAC (Hash-based Message Authentication Code) to secure data confidentiality and integrity when stored on cloud servers. Drawing on research on ECG image file encryption using ECDH and AES-GCM, we choose AES-GCM for its high resistance to manipulation and unauthorized access, while ECDSA (Elliptic Curve Digital Signature Algorithm) improves data authenticity. This method encrypts files before uploading them to the cloud, data is secure even if intercepted. In addition to a user friendly interface, the system is tuned for performance, evaluating encryption and decryption times and file sizes. Given the concerning trend of stolen encrypted data being sold on the dark web, as reported in recent headlines, our project offers a secure and effective method for safeguarding critical information in cloud storage

Data WHO pada tahun 2023 menunjukkan bahwa sekitar 280 juta orang di seluruh dunia mengalami depresi. Diperkirakan sekitar 3.7% orang dari populasi di Indonesia dinyatakan menderita depresi. Dilansir dari Databoks, Jawa Timur tercatat memiliki angka depresi sebesar 4.5%, mendekati provinsi dengan angka depresi tertinggi di Indonesia. Berdasar dari beberapa studi terdahulu, salah satu faktor penyebab depresi pada individu dewasa adalah Adverse Childhood Experiences. Penelitian ini bertujuan untuk mengetahui apakah ada pengaruh Adverse Childhood Experiences terhadap kecenderungan depresi pada individu dewasa awal. Penelitian ini menggunakan pendekatan kuantitatif korelasional. Partisipan penelitian ini adalah individu dewasa awal berjumlah 106 subjek yang pernah mengalami Adverse Childhood Experiences dan berdomisili di Jawa Timur, subjek diambil menggunakan teknik purposive sampling. Instrumen dalam penelitian ini menggunakan skala Adverse Childhood Experiences Scale dan skala Beck Depression Inventory II. Metode analisis data yang digunakan adalah menggunakan Uji Regresi Linier Sederhana. Hasil penelitian menunjukkan bahwa Adverse Childhood Experiences berkontribusi positif secara signifikan terhadap kecenderungan depresi pada dewasa awal sebesar 14.8%. Semakin tinggi Adverse Childhood Experiences, maka semakin tinggi pula kecenderungan depresi. Selain itu, dimensi kekerasan berkontribusi positif sebesar 12.5%, sedangkan dimensi disfungsi keluarga berkontribusi positif sebesar 7.8% terhadap kecenderungan depresi pada dewasa awal.
