Berdasarkan data Badan Pusat Statistik, pertumbuhan penduduk di Indonesia mencapai 2 juta – 3 juta jiwa per tahun. Dalam hal ini, adanya peningkatan pertumbuhan penduduk, maka kebutuhan akan rumah juga meningkat. Tingginya permintaan akan perumahan memberikan peluang bagi perusahan properti(real estate), salah satunya adalah PT Anugerah Indah Prima yang berada di Kota Medan. Selain memberikan peluang yang besar, bisnis di bidang real estate juga memiliki persaingan yang ketat sehingga untuk dapat terus maju dan berkembang, PT Anugerah Indah Prima harus terus memiliki inovasi dalam mengembangkan bisnisnya. Dalam membuat suatu keputusan untuk mengembangkan bisnisnya, perusahaan tersebut masih menghadapi kendala, yaitu melakukan pengolahan data penjualan properti secara manual menggunakan Microsoft Excel. Pengolahan data tersebut belum dapat memenuhi kebutuhan manajer dan pihak marketing dalam pengambilan keputusan karena laporan yang dihasilkan masih berupa informasi umum dan sulit dipahami.
Oleh karena itu, penelitian ini berfokus pada perancangan dashboard yang dapat memberikan wawasan informasi dalam pengambilan sebuah keputusan pada perusahaan. Pada penelitian ini memanfaatkan business intelligence, ETL(extract, transform, dan loading), OLAP(online analytical processing), dan forecasting.

Authors: Vashisht Anuj , Vishwanathan Jithesh , Vashisht Shruti , Sood Chetan , Sarin Puneet , Ray K. Rahul 
Published: February 2025

Background & objectives
The procurement of medical items (drugs and consumables) through the Government e-marketplace (GeM) is a recent initiative. This study aimed to comprehensively assess the bottlenecks, procedural pitfalls, and delays impacting the supply chain in the procurement process of a tertiary care hospital in northeast India.

Methods
A retrospective analysis was conducted on the procurement data obtained from the hospital’s procurement cell over 12 months. The study primarily focused on the total demand for medicines and consumables through the e-portal and compared it with the actual quantity/quality received by healthcare facilities.

Results
The initial demand was placed for 1507 medicines and 1219 medical consumables. However, the healthcare facility received only 695 (46.1%) medicines and 945 (77.5%) consumables. Major bottlenecks identified were non-quotation of medicines, price negotiation rejections, and vendor failure to supply.

Interpretation & conclusions
This study identifies a few bottlenecks: non-quotation by vendors, price negotiation rejections and failure to supply medicines and consumables by the vendors in procurement through the GeM. Efforts like flexibility in matching previous purchase rates, International Organisation for Standardisation/World Health Organization (ISO/WHO) qualified vendor base at the GeM level and porting in reliable pharmaceutical companies must be directed towards optimising procurement processes and enhancing supply chain management to bridge the identified gaps and promote seamless healthcare delivery.

Published: February 2025

В статье рассматриваются правовые аспекты понятия и идентификации товаров и технологий двойного назначения в российском законодательстве и международном праве. Основное внимание уделяется цели законодательных норм, т. е. обеспечению национальной безопасности и выполнению международных обязательств. Рассматривается значимость правового регулирования передачи продукции военного и двойного назначения для поддержания стабильности и безопасности как на региональном уровне (в том числе в муниципальных образованиях, находящихся в непосредственной близости от зоны проведения специальной военной операции), так и на национальном, и на международном. Исследуются перспективы внедрения новых технологических решений, в частности искусственного интеллекта и блокчейна, для повышения эффективности контроля и прозрачности операций с товарами двойного назначения. Обосновывается необходимость совершенствования правового регулирования с учетом меняющейся геополитической обстановки и развития технологий.
The article examines the legal aspects of the concept and identification of dual-use goods and technologies in Russian legislation and international law. The main attention is paid to the purpose of legislative norms - ensuring national security and fulfilling international obligations. The importance of legal regulation of the transfer of military and dual-use products for maintaining stability and security at the regional (including among municipalities located in the immediate vicinity of a special military operation), national and international levels is considered. The prospects for the introduction of new technological solutions, in particular artificial intelligence and blockchain, to improve the efficiency of control and transparency of transactions with dual-use goods are studied. The need to improve legal regulation is substantiated, taking into account the changing geopolitical situation and technological development.
Customer Churn Prediction Using the RFM Approach and Extreme Gradient Boosting for Company Strategy Recommendation
Authors: Irawan Mohammad Isa , Putris Nadhifa Afrinia Dwi , Muhammad Noryanti binti 
Published: February 2025

Customers are vital assets in the growth and sustainability of business organizations. However, customers may discontinue their engagement with a company and switch to competitors’ products or services for various reasons. This event referred to as customer churn. Losing customers significantly impacts a company's revenue, often resulting in financial decline. Churn events, which are subject to dynamic monthly changes, are further influenced by intense competition and rapid technological advancements. Analyzing customer characteristics is crucial to understanding customer behavior, with metrics such as recency, frequency, monetary (RFM) serving as key indicators of subscription and transaction patterns. The Extreme Gradient Boosting method is applied to address the challenge of classifying churn and non-churn customers. The prescriptive analytics process is carried out to identify the features most influential in prediction outcomes, enabling the formulation of strategic recommendations to mitigate churn problems. The integration of RFM analysis with the XGBoost method provides optimal results, particularly in the third segmentation, achieving an accuracy of = 0.98833, precession = 0.98768, recall = 0.98899, and f1-score = 0.98833. The prescriptive analytics process highlights three critical features, namely city factor, GMV generation, and total customer transaction generation. This findings demonstrate that the segmentation characteristics, data representation, and behavioral approach with RFM analysis have an effect on improving the performance of the model in churn prediction.

Intracranial epidermoid cyst with malignant degeneration and leptomeningeal carcinomatosis: illustrative case
Authors: Alsadi Hussein , Dahlstrom Kelly , Summers Kyle , Camarata Paul J. , Werth Kyle 
Published: February 2025

BACKGROUND
Malignant transformation of epidermoid cysts (ECs) into squamous cell carcinoma (SCC) is extremely rare, with associated leptomeningeal carcinomatosis being much less likely. Malignant transformation of ECs has a poor prognosis with a median overall survival of 10 months following transformation.

OBSERVATIONS
A 59-year-old male with a history of a subtotally resected posterior fossa EC presented with worsening symptoms 14 years following the initial subtotal resection. Imaging showed obstructive hydrocephalus and extensive leptomeningeal carcinomatosis. Laboratory workup confirmed malignant transformation to SCC.

LESSONS
Nonmalignant recurrence of benign ECs is relatively common, often due to the complexity of complete resection and adherence to adjacent neurovascular structures. On the other hand, malignant degeneration of an EC is extremely rare. Any rapid change in symptoms, failure to recover following surgery, and new areas of irregular thickening and enhancement on imaging should prompt further evaluation for this process.

Intraoperative Electrically Evoked Auditory Brainstem Response (eABR) examination in cochlear implant candidacy
Authors: Zizlavsky Semiramis , Saleh Rangga Rayendra , Priyono Harim 
Published: February 2025

Background: Cochlear implantation is one of the most promising hearing habilitation methods for patients with profound sensorineural hearing loss (SNHL). One of the difficulties associated with the method is predicting the outcome of the surgery, especially in patients with cochlear nerve abnormalities. Purpose: To evaluate the intraoperative cochlear nerve response using Electrically Evoked Auditory Brainstem Response (eABR), and determine if cochlear implantation was required. Clinical question: How significant was intraoperative eABR in determining the outcome of cochlear implantation? Case report: This study considered two cases with profound bilateral SNHL that underwent intraoperative eABR. The first case involved 10-year-old girl who had used conventional hearing aids for eight years before surgery. She practiced lip reading for communication. The second case involved 4-year-old boy with delayed speech and a history of febrile seizure when he was two years old. He had used a conventional hearing aid for six months. Method: Evidence based literature was conducted through PubMed, Embase, and Wiley. Result: On the first case, eABR examination evoked no response in both ears and the parents decided not to carry on with the surgery. In the second case, eABR examination aroused a significant response in both ears, so the implantation was performed. Three months postoperative, the child was babbling and able to detect sound. Conclusion: eABR could give valuable input in identifying profound bilateral SNHL patients with cochlear nerve abnormality. The high cost of implant devices makes this examination beneficial for the patient’s family in deciding if implantation surgery is required.

Published: February 2025

Problems that may affect patient satisfaction in basic health services, including the appearance of the hospital building is convincing and attractive, the hospital environment is clean and comfortable, the hospital is open on time, the seats where the turn is available are sufficient, the staff greets politely, is friendly and wants to help, the health worker listens to the patient's complaints, the health worker checks carefully and thoroughly, Health workers provide complete information, medicines needed by patients are available at the hospital. The purpose of this study is to determine the effect of outpatient health services on the satisfaction of BPJS Kesehatan participants. This type of research is an analytical survey with a cross sectional approach using primary data with questionnaires and secondary data from the report of Prima Inti Medika Hospital North Aceh. The population in this study is all outpatients of BPJS Kesehatan participants who visited Prima Inti Medika Hospital as many as 1,120 people with a sample of 95 people determined using the acidental sampling method. The analysis used univariate, bivariate and multivariate analysis. The results of the chi square test showed that responsiveness (p= 0.001 < 0.05), reliability (p= 0.000< 0.05), assurance (p= 0.002< 0.05), concern (p= 0.000 <0.05) and physical evidence (p= 0.060 > 0.05). The logistic regression test showed that the most influential variable on patient satisfaction was concern with an Exp (B) value of 4.781. The conclusion of this study is that there is an influence of responsiveness, reliability, assurance, and care have a relationship with patient satisfaction, while physical evidence has no relationship with patient satisfaction. Efforts are needed to improve the quality of outpatient services by increasing a sense of full attention, quick response to patient problems, not discriminating between patients and others, being able to provide a good response in responding to patient complaints in order to establish a harmonious relationship between health workers and patients in order to achieve services that are able to satisfy patients.
Порівняння двох підходів до Unit-тестування Angular-додатків
Authors: Полупан Ю.В. , Родіонов П.Ю. , Дьомін М.К. 
Published: February 2025

В сучасному світі реактивні системи набирають все більшої популярності, при цьому в основі реактивності є робота з асинхронними потоками даних. Тестування реактивних систем стоїть окремою задачею, в якій є низка відкритих питань, наприклад, вимирювання ефективності тестів, використовуючі той чи інший підхід до тестування.
Для тестування Angular-додатків в роботі було обрано два підходи: 1) з використанням зв’язки Jasmine + Karma, що встановлюється за замовчуванням при створенні додатку; 2) з використанням Jest.
В статті тестується Angular-додаток, який має 7 тестів, 3 з яких – тести синхронних блоків коду і 4 – для асинхронних блоків. При тестуванні використовувались інструменти, що пропонує Angular із коробки та фреймворк Jest.
Для вимирювання ефективності Unit-тестів, як правило, використовуються чотири критерії [2, 4]: захист від помилок (protectionagainstbugs); стійкість до рефакторингу (resiliencetorefactoring); швидкість зворотнього зв’язку (fastfeedback); простота підтримки (maintainability). Порівнюючи різні підходи до тестування можна визначити як той чи інший підхід впливає на конкретний критерій ефективності Unit-тестів, підвищуючі його, або навпаки зменшуючі. Як відомо, на сьогодні не існує автоматичного способу вимірювання ефективності з отриманням значень для кожного критерію і тому кожен тест потрібно оцінювати окремо. Для отримання значення по критерію «швидкість зворотнього зв’язку» будемо використовувати час виконання тестів, в тому числі з визначенням відсотка покриття коду тестами при допомозі команди coverage. Цей критерій показує, що чим швидше виконується тест на етапі розробки, тим меньше часу витрачається на усунення знайденних помилок, тим самим, значно підвищуючи ефективність Unit-тестів.
В результаті порівняння роботи двох фреймворків для тестування, можно зробити висновок, що при використанні Jest тести виконуються в середньому на 60% швидше за рахунок того, що система відстежує зміни файлів та не виконує непотрібних дій. При тестуванні ассинхронного коду така ж тенденція (збільшення швидкості тестування на 60%) зберігається, тому Jest відмінно підходить для виконання тестування Angular-проектів, які містять багато асинхронного коду.
Так як ефективність Unit-тестів залежить від швидкості зворотнього зв’язку (fastfeedback), то, використовуючіJest, ми, тим самим, значно підвищуємо ефективність Unit-тестування та всього проекту вцілому.

BackgroundPHACE syndrome is an uncommon disorder, marked by large segmental hemangiomas on the face and various developmental anomalies. Significant advancements have been made in its diagnosis, imaging, and understanding of complications since 1996.Case SummaryWe describe the first diagnosis case of PHACE syndrome in a one-month and 19-day-old infant who presented with a large facial hemangioma and coarctation of the aorta originating from the left common carotid artery, along with an aberrant course of the right subclavian artery. The complementary diagnostic studies, their surgical correction, and their progression are described.DiscussionGiven the rarity of the syndrome (the PHACE Syndrome International Clinical Registry and Genetic Repository has over 270 enrolled individuals) and the importance of early diagnosis of some anomalies it comprises, particularly cardiovascular anomalies, dissemination is considered crucial for general and pediatric cardiologists.
