Pandemi Covid-19 sampai dengan tahun 2021 masih berpengaruh bagi perekonomian masyarakat. Sektor pariwisata yang dinilai menimbulkan multiplier effect bagi perekonomian cukup besar turut lumpuh karena pembatasan mobilitas. Desa Wisata menjadi harapan besar bagi mitigasi pandemi, karena menggerakkan perekonomian masyarakat mulai dari wilayah administratif terkecil. Masyarakat desa, didorong untuk mampu mengakselerasi penggunaan teknologi sebagai faktor produksi untuk meningkatkan output /produk. Realita di lapangan menunjukkan bahwa belum semua pelaku usaha dan BUMDes menggunakan e-commerce dalam mempromosikan dan memasarkan hasil usahanya. Kegiatan Pengabdian kepada masyarakat ini, bertujuan untuk menberikan recharging dan pembekalan teknologi untuk meningkatkan penjualan produk desa wisata melalui e-commerce. Khalayak sasaran dalam kegiatan ini adalah pelaku UMKM dan pengelola BUMDes di Desa Kopeng Kecamatan Getasan. Metode kegiatan pengabdian kepada masyarakat menggunakan ceramah, praktik dan pendampingan. Pertama peserta akan diberikan ceramah mengenai e-commerce. Selanjutnya peserta akan praktik memanfaatkan e-commerce. Hasil kegiatan pengabdian kepada masyarakat menunjukkan adanya peningkatan pemahaman dan penggunaan terhadap e-commerce.
The Covid-19 pandemic until 2021 will still affect the community's economy. The tourism sector, which is considered to have a significant multiplier effect on the economy, is also paralyzed due to restrictions on mobility. Tourism villages are a big hope for pandemic mitigation because they move the community's economy from the smallest administrative area. Village communities are encouraged to be able to accelerate the use of technology as a factor of production to increase output/product. The reality in the field shows that not all business actors and BUMDes use e-commerce to promote and market their business results. This community service activity aims to provide recharging and technology supplies to increase sales of tourist village products through e-commerce. The target audience in this activity is SME actors and BUMDes managers in Kopeng Village, Getasan District. The method of community service activities uses lectures, practices and mentoring. First, participants will be given a lecture about e-commerce. Furthermore, participants will practice using e-commerce. The results of community service activities show increased understanding and use of e-commerce.

Objectives
To investigate the utility and effectiveness of a school outreach programme in areas of lower socioeconomic status to improve understanding of common endocrine topics and the medical profession.

Methods
Two secondary school outreach sessions were conducted in July 2022. Students were invited to attend lectures delivered by medical professionals and engage in poster-making sessions using the knowledge they had gained throughout the day. Participants completed anonymised pre- and post-session surveys. Outcomes were identified using Kirkpatrick’s training evaluation model. Self-reported perceptions and beliefs (Kirkpatrick’s level 2a) were compared using chi-square tests. Thematic analysis of team-led poster presentations was performed.

Results
Of the 254 participants included, the response rates of pre- and post-session questionnaires were 75.6% and 56.2%, respectively. The outreach day increased students’ understanding of obesity and diabetes, polycystic ovary syndrome, and Health Technology. The most well-received activities from the outreach day were voted to be the poster challenge (43.4%) and poster presentation (14.7%). Following the session, there was a trend towards an increased understanding of medical careers and interest in pursuing a medical career, although these did not reach statistical significance.

Conclusions
Outreach programmes could be a practical and effective approach to engaging prospective medical applicants from areas of lower socioeconomic status. Further studies are required to expand outreach programmes and investigate the efficacy of school engagement programmes.
The gut microbiome without any plant food? A case study on the gut microbiome of a healthy carnivore
Authors: Karačić Andrija , Dikarlo Plamena , Dorst Isabel , Renko Ira , Liberati Pršo Ana-Marija 
Published: October 2024

Objective
The carnivore diet is a ketogenic diet based exclusively on the consumption of food of animal origin. While the impact of various diets on the gut microbiome is extensively documented, the effects of a carnivore diet remain unclear. To address this gap, we conducted a pilot study on the gut microbiome of an individual following a carnivore diet and compared it with that of a subgroup of healthy individuals.

Methods
A stool sample was collected from a healthy 32-year-old male adhering to a carnivore diet and was sequenced using 16S DNA Amplicon Sequencing. The results were then compared to those from three control groups possessing similar anthropometric characteristics and differing in their frequency of meat consumption.

Results
The gut microbiome of the carnivore was dominated by the phylum Firmicutes and the genera Faecalibacterium, Blautia, unspecific Lachnospiraceae, Bacteroides, and Roseburia—bacteria known for fiber degradation. Furthermore, neither alpha- nor beta-diversity, nor the functional capacity of the gut microbiome, showed differences when compared to the control groups. Additionally, the gut microbiome of the carnivore showed the least similarities with the microbiome of the cohort consuming meat on a daily basis.

Conclusion
In our study, we showcase the compositional and functional characteristics of the gut microbiome in an individual on a carnivorous diet, finding no differences in comparison to a control cohort. Further research is needed to investigate the short- and long-term impacts of a carnivorous diet on gut health through cross-sectional and longitudinal studies.

Significance statement
To the best of our knowledge, this is the first study to report on the composition of the gut microbiome of a person adhering long-term to the carnivore diet.

Abstract
The last National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI) was published in 2003. In advance of the 2025 PRVI NSHM update, we created three geologic input databases to summarize new onshore and offshore fault source information in the northern Caribbean region between 62°–70° W and 16°–21° N. These databases, of fault sections, fault-zone polygons, and geologic estimates of fault activity (fault-slip rate and earthquake recurrence intervals) at specific sites, document updates to fault parameters used in prior seismic hazard models in PRVI. Fault sources were reviewed from published studies since 2003, which document substantial changes to the understanding of fault location, geometry, or activity. New fault section sources were added for features that meet the criteria of (1) length ≥7 km, (2) unequivocal evidence of recurrent tectonic Quaternary activity, and (3) documentation that is publicly available in a peer-reviewed source. In addition, we revised several broad areal sources, such as the Mona and Anegada extensional zones. The 2003 model included three fault sections and two fault-zone polygons (areal sources). These databases include 35 fault sections, 6 fault-zone polygons, and 51 earthquake geology sites. To characterize fault activity rates, slip-rate bins were assigned based on landscape expression and paleoseismic trench observations for faults without published slip-rate sites. Additional fault sources were evaluated but not included in these databases due to a lack of published information about fault location, geometry, or recurrent Quaternary activity. The PRVI NSHM 2025 geologic input databases describe crustal faulting; the geometries and coupling of Puerto Rico subduction zone and Muertos Trough models are considered in a separate database. Updates to the fault sections, fault-zone polygons, and earthquake geology databases can help inform the location and recurrence rate of damaging earthquakes in the PRVI NSHM implementation.

Stock price volatility is a measure of how far a stock price moves in a given Stock price volatility is a measure of how far a stock price moves in a given time. The theory developed by Black-Scholes states that every option price with the same 'underlying asset' and the same time to maturity but with different exercise values will have the same Implied Volatility value. However, this is not always the case in the market. Therefore, it is necessary to estimate volatility known as Implied Volatility, which is considered an appropriate method in estimating volatility values. This study compares the Bisection and Secant methods to estimate the volatility of Apple Inc. (Aapl) stock. This study uses data on the closing price of the stock in the period September 29, 2022 to September 29, 2023. Volatility estimation for the Bisection and Secant methods by determining the initial approximation and limiting it to a maximum of 100 simulations and iteration stops if it has produced a relative error smaller than = . The is an error tolerance limit, the smaller the error tolerance, the more accurate it is. According to the research results, the Bisection method produces an estimated volatility value of 0.498212 at the 9th iteration, while the Secant method produces an estimated value of 0.498590 at the 10th iteration. The Secant method produces a smaller relative error value of 0.000096, indicating that the Secant method is more accurate than the Bisection method.

The Black-Scholes Method is one of the option pricing method that introduced by Fischer Black and Myron Scholes in 1973. This study aim to review the determination of the price of an option with stocks as the underlying assets and based on Black and Scholes assumptions. These assumptions lead to construct an equation named Black-Scholes differential equations, which is the equation that must be satisfied for option as the derivative instrument and non-dividend giving stocks as the underlying assets. After the Black-Scholes differential equations formed successfully, the next step is to find the solution of that equation. Consider the option is call option, the solution that will be obtained from solving the equation is the price of call option. Then substitute it to the put-call parity equation, which is the equation that shows the relationship between call and put option prices, so the price of put option can be obtained too. The estimation that obtained from the Black-Scholes method is the highest price for a contract is said to be fair and worth to buy for the holder.

Inflation is a phenomenon that shows a continuous increase in the price of goods, which can cause a decline in the economic condition of a country. One of the indicators used to measure the inflation rate is the Consumer Price Index (CPI). By knowing the CPI value earlier, food prices can be controlled to be more stable. One method that can be used to predict CPI is Support Vector Regression (SVR), where this method is able to overcome linear and non-linear data conditions. This research aims to get the best prediction for CPI in South Kalimantan Province using CPI data for food groups in Tanjung, Banjarmasin, and Kotabaru in the 2014-2022 range. The best prediction results are obtained through the SVR method with Linear Kernel. The prediction error value measured through the MAPE value for Tanjung, Banjarmasin and Kotabaru is 0.77%, and . While the size of the meaning of the model measured through the coefficient of determination, respectively 0.8826, and . Based on these values, it is concluded that the prediction model formed is very good and feasible. The prediction results for the next 12 months show an increase, so that the government and related parties can formulate policies such as market operations and subsidy programs for the community.

Abstract
JBJS convened a symposium to discuss the reporting of sex and gender in research studies as an imperative to improve research methods and results to benefit all patients. Barriers to improved reporting include a lack of societal and cultural acceptance of its need; a lack of education regarding appropriate terminology and appropriate statistical methods and efficient study designs; a need for increased research funding to support larger group sizes; unknown concordance of cell and animal models with humans to reflect biologic variables such as sex; and a lack of understanding of key considerations of gender, race, and other social determinants of health and how these factors intersect. Attention to developing and disseminating best-practice statistical methods and to educating investigators (at all career levels), reviewers, funders, editors, and staff in their proper implementation will aid reporting. Concomitantly, well-designed studies with sufficient rigor and adequate resources are essential to enable meaningful and reproducible research. Existing recommendations, such as the Sex and Gender Equity in Research (SAGER) guidelines, provide valuable guidance that can be applied across the research ecosystem. Academic institutions and private foundations are likely groups to assist in scientific and institutional review board guidance and study recruitment and pilot funding to generate meaningful power estimates, and to serve as sources for additional funding and presentation of workshops, educational events, and seminars. All of this needs to be conducted on an ongoing basis to ensure that sex and gender are considered in scientific analyses, where relevant.
Immobilization of Vibrio cholerae S1 (NAG) L-Glutaminase on Different Supports
Authors: Hassan Shatha Salman 
Published: October 2024

تـــــم الحصـول عـــــلـــى ست عشرة عزلة لبكتريا Vibrio منتجة لانزيم الكلوتامينيز (L-glutaminase) من نماذج سريرية ومياه ، وانتخبت عزلة واحدة اعتماداً على انتاجيتها الاعلى للانزيم ، وشخصت على انها Vibrio cholerae (NAG) واعطي لها الرمز S1.
نميت البكتريا في وسط سائل (يحتوي على الكلوتامين) ، واستخلص الانزيم من الخلايا بعد تكسيرها بالموجات فوق الصوتية.
ورسب الانزيم باستعمال كبريتات الامونيوم بنسبة اشباع 30% ، وتمت ديلزته ، ثم قيد بامتزازه على مواد ساندة مختلفة تضمنت السيفادكس (Sephadex G-100) ، ومسحوق السليلوز ، والنشا ، وهلام السليكا ، والخرز الزجاجية ، والفحم.
بينت النتائج ان Sephadex G-100 يحتفظ بمعظم فعالية الانزيم (90 %) يعقبه النشا (78 %) ثم هلام السليكا والسليلوز (71 %) بينما أحتفظ الفحم والخرز الزجاجية بـ 58 % فقط من فعالية الانزيم.
تم تعريض الانزيم المقيد والحر لدرجات حرارية وقيم رقم هيدروجيني مختلفة ، ولوحظ ان الانزيم المقيد اكثر ثباتاً من الانزيم الحر في درجات الحرارة المختلفة وقيم الرقم الهايدروجيني ، واظهر هلام السليكا حماية جيدة للانزيم في درجات الحرارة العالية إذ بقي محتفظاً بـ 54 % و 22 % من الفعالية الاصلية عند تعريضه لدرجة 50 و 60م لمدة ساعتين على التوالي في حين احتفظ الانزيم الحر بـ 30 % و 10 % في هاتين الدرجتين.
لوحظ ان الانزيم المقيد اكثر ثباتاً برقم هايدروجيني 7 مما عليه برقم 4 او 10 واحتفظ الانزيم المقيد بالسيفادكس (Sephadex G-100) باعلى نسبة فعالية (98 %) عند الرقم الهايدروجيني 7 لمدة ساعتين بينما احتفظ الانزيم الحر بـ 73 % في الظروف نفسها. وعندما حفظ الانزيم المقيد بدرجة 4م لمدة شهر بقي محتفظاً بـ 35 % من فعاليته قياساً بالانزيم الحر الذي احتفظ بـ 18 %.
من هذه النتائج يتبين ان انزيم الكلوتامينيز المنتج من بكتريا V. cholerae S1 يمكن تقييده بطريقة الامتزاز على مواد مختلفة ، وان Sephadex G-100 مادة ملائمة لتقييده والحفاظ على فعالية عالية ، وان هلام السليكا يحمي الانزيم من الحرارة العالية بشكل افضل من غيره والانزيم المقيد عموماً اكثر ثباتاً من الانزيم الحر في درجات الحرارة وقيم الرقم الهيدروجيني المختلفة فضلاً عن ثباته الخزني.

يعتبر تصحيح بلوخ ( Bloch correction) من التصحيحات المهمة لقدرة الإيقاف (Stopping power) لكونه يربط الوصف الكلاسيكي للعالم بور(Bohr) مع المعالجة الكمية للعالم بيتا(Bethe).
تم في هذا البحث إجراء دراسة حول اعتماد تصحيح بلوخ على فرق الطور و لمديات مختلفة من طاقة الجسيم, و تبين إن تصحيح بلوخ في حالتيه النسبية(γ=Ε⁄mc²→0) واللانسبية(γ→1) يعتمد على فرق الطور و طاقة الجسيم (γ) و لكن في الحالة الفوق نسبية لتصحيح بلوخ (∞ →γ) يعتمد على فرق الطور فقط .
وتم حساب قدرة الإيقاف الالكترونية في السرع الواطئة بدلالة فرق الطور.
