Mechanism of Share Transfer Through Court Decision for Shareholders in a State of Absence (Afwezigheid)
Get PDFThere are many problems found in the civil aspect these days, which are diverse and complex, so comprehensive arrangements are needed to fulfil all civil rights in humans as one of the subjects of civil law. This research will specifically discuss the state of Afwezigheid as a shareholder of a limited liability company where the assets owned are in the form of shares. To carry out the civil rights of an absent person (Afwezig), a determination of Afwezigheid is required by the local District Court, which then appoints Balai Harta Peninggalan (BHP) as a Special Manager (Bewindvoerder) to carry out management of the absent person's assets. This research is a normative legal study using secondary data, applying statute approach, conceptual approach, and historical approach. The data were collected through literature review of books, laws, and regulations relating to the state of Afwezigheid and its position under the Civil Code and Law Number 40 of 2007 on Limited Liability Company. The findings indicate that the absence (Afwezigheid) of a shareholder must be established by a court ruling, with BHP managing the shareholder’s rights and assets. However, the lack of clear technical procedures for share transfer creates legal uncertainty in practice
Dapsone Induced Methemoglobinemia in Pediatric Patient: A Case Report
Get PDFBackground: Acquired methemoglobinemia is significantly more common than the congenital form, though it remains a rare condition. Most cases arise from accidental chemical exposure or the use of topical and local anesthetics.
Case Description: We present a case of 14-year-old male presented with complaints of dark grayish discoloration of the skin on the face and hands, persisting for the past two months prior to admission. He was later diagnosed with dapsone induced methemoglobinemia. Patient was then discharged with oral therapy consisting of agents with antioxidant properties and instructed to discontinue dapsone consumption.
Conclusions: In pediatric patients undergoing dapsone therapy, the risk of dapsone induced methemoglobinemia should be carefully considered to ensure early identification and prompt management, thus minimizing the potential for severe complications
Investigating the Prognostic Value of Serum Albumin Levels in Patients Undergoing Hemodialysis: A Systematic Review and Meta-analysis
Get PDFBackground: Hypoalbuminemia, characterized by low serum albumin levels, is frequently observed in patients undergoing hemodialysis and has been identified as a potential predictor of increased mortality risk. This systematic review aims to evaluate the relationship between hypoalbuminemia and mortality in hemodialysis patients, assessing the prognostic value of serum albumin levels as an indicator for patient outcomes.
Methods: A comprehensive search was conducted in databases including PubMed, Europe PMC, and Scopus to identify relevant studies. Studies were included if they investigated the association between serum albumin levels and mortality outcomes in adult patients undergoing hemodialysis. Data extraction was performed independently by two reviewers, focusing on study characteristics, patient demographics, albumin levels, and mortality outcomes. Quality assessment of studies was conducted using the Newcastle-Ottawa Scale (NOS).
Result: A total of eight studies, encompassing 45,178 hemodialysis patients with a mean age in the 50s, met the inclusion criteria. The studies had a combined male cohort of 22,501 individuals. The definition of hypoalbuminemia varied across studies, with cutoff values ranging from 3.0 to 3.9 g/dL. Follow-up durations spanned from as early as 3 months to a maximum of 6.1 years. The meta-analysis revealed a pooled hazard ratio (HR) of 1.08 (95% CI: 0.94–1.25), suggesting a non-significant association between hypoalbuminemia and increased mortality risk (P = 0.28). However, substantial heterogeneity was present (I² = 79%), indicating variability across studies.
Conclusions: Hypoalbuminemia showed a non-significant association with mortality in hemodialysis patients, though variability across studies suggests further research is needed for clarity

Get PDFThis research is focused on the implementation of the MilleaLab VR platform for teaching English to a student with ADHD at SMP Plus Rahmat, Kediri, Indonesia. Traditional methodologies in teaching are often less engaging for students with ADHD, and alternative methods are increasingly needed. That is where Virtual Reality comes in. MilleaLab can offer an interactive learning environment that takes away stress, maintains focus, and increases interest in learning. After going through Narrative Inquiry, one could deduce that the participant was interested in learning because of the enrichment through Virtual Reality learning. The student was very keen to learn and was more relaxed when it came to learning English; this meant that Virtual Reality did have some advantage over its rivals. The student showed a more profound understanding of the stories told during the classes and seemed to remember them more; this would mean that VR can significantly improve memory and understanding. This points to the need to offer teaching techniques relevant to each individual for the students to continue their studies with success. These findings point out Virtual Reality as the preferred method of teaching, where the student mentioned the desire to continue working on MilleaLab. The results form an emerging understanding of the place of VR within inclusive education and point to some potentially productive directions for further research into the use of technology within diverse learning environments.

Get PDFAir quality, wind speed, and wind direction monitoring system is a system that can measure environmental parameters that affect human health and comfort, as well as displaying real-time measurement data through an application. This system is designed and built using ESP32 microcontroller and data visualization using Blynk IoT platform. The system consists of three main components, namely sensors, microcontroller, and IoT platform. The sensors used are DHT22 sensor to read temperature and humidity, MQ135 sensor to read CO2 concentration, anemometer sensor to read wind speed, and wind direction sensor to read wind direction. These sensors send data to the ESP32 microcontroller, which then processes the data and sends it to the Blynk server via an internet connection. In addition, the measurement data is also automatically sent to a Google Spreadsheet using the Google Sheets API. This allows users to save data in a tabular format, perform further analysis, and store measurement history in the cloud. The Blynk app displays measurement data in the form of graphs, numbers, and color indicators. The test showed that the system can function well in measuring environmental parameters. Verification showed that the average relative errors in reading the parameters are as follows: temperature 1.7%, humidity 1.63%, CO2 concentration 1.99%, and wind speed 0.02%. These error values are within accepted tolerance level, hence the system is sufficiently accurate to measure environmental conditions.

This package is an interface between the yacas system and R, combining symbolic and numerical computation capabilities in one system. This study aims to explore and document R's capabilities in symbolic computation using Ryacas. There are three topics that will be discussed in this research, namely 1) precision of arithmetic calculations, 2) application to linear algebra, and 3) application of symbolic computation to solving Mathematics-Statistics cases. Ryacas is able to increase the precision of numerical calculations in simple arithmetic cases, and operations in linear algebra. The case of obtaining the probability distribution function and probability density function of a random variable U which is a function of a random variable Y, can be easily solved by Ryacas. The output of symbolic computation from this last case is further processed numerically by R in the form of a graphical appearance, with the ggplot2 package. Likewise, the simulation process is carried out to generate the values of the random variable U. These results illustrate the continuous process between symbolic and numerical computation in one system, in this case R.
