Published: July 2024

Abstract: Information content that meets user needs is an important aspect of a website. Quality testing, especially for sites that have never been tested, is necessary to ensure effectiveness. This research uses observation techniques, questionnaires, and literature studies related to the Webqual method and the End-User Computing Satisfaction (EUCS) variable. The variables used include Usability, Information Quality, Service Interaction Quality, User Satisfaction, and Content. The Webqual model is applied in this research through a questionnaire, which produces various data from respondents. The data is then processed and analyzed to produce accurate statistical data. From this research, the results of the questionnaire show that Service Interaction Quality has a low percentage, namely 72.72% (X3.2), where the full percentage is 100%. Apart from that, User Satisfaction also has a low percentage, namely 70.90% (Y.1). This shows that the Quality of Service Interaction has less than a positive effect on User Satisfaction. Therefore, improvements are needed in the Quality of Service Interaction section on the PT Yudo Indonesia website so that User Satisfaction also increases, especially in the aspects of security and meeting user needs. Keywords: EUCS; website quality; webqual Abstrak: Konten informasi yang memenuhi kebutuhan pengguna adalah aspek penting dari sebuah situs web.

Published: July 2024

The increasing population in several countries, including Indonesia, leads to a heightened demand for food, a significant portion of which comes from animal sources. Various efforts have been made by different parties to meet the soaring demand for animal meat. Although there is a growing trend of individually managed livestock enterprises, failure risks are frequent, often resulting in suboptimal economic outcomes. Accordingly, this study aims to evaluate the factors influencing the success of livestock businesses. Furthermore, this research also intends to develop a mathematical model to predict potential profits, taking these factors into account. The framework is developed based on the analytic hierarchy process (AHP) and multiple linear regression (MLR). This proposed framework is demonstrated in a pig farming business located in Wamena, Papua, Indonesia. The results indicate that out of six identified criteria, four are most significant in affecting livestock success: culture (C5), pig breed (C2), gender (C1), and physical condition (C4). Additionally, to build a mathematical model for predicting profits, a dataset comprising 44 combinations of sub-criteria has been constructed. The mathematical model shows a prediction capability of 84.3%, indicating very strong correlation. Although the livestock success evaluation model developed in this study is tested only on one type of livestock, the framework, in general, can be adopted for other types of business ventures.

Collodion baby with cholestasis is an uncommon condition. The term "collodion baby" refers to newborns with thick skin covering their entire body. Neonatal cholestasis is a form of conjugated cholestasis hyperbilirubinemia caused by reduced bile flow. The condition causes persistent jaundice (over two weeks) and elevated conjugated bilirubin. Genetic abnormalities or gene mutations have been reported in neonatal ichthyosis syndrome with cholestasis.
A case report of a collodion baby, a rare congenital condition characterized by a parchment-like membrane covering the entire body, was brought to Dr. Soetomo General Academic Hospital. Prolonged jaundice was one of the other findings. A skin biopsy found characteristics consistent with the diagnosis of collodion in a newborn. The paediatric team managed this case, which was treated in collaboration with a dermatologist. This case showed that newborn collodion syndrome required skin care, cholestasis screening, and jaundice management from birth.

Malaria is a major infectious disease worldwide, and vaccination is essential for disease control. The Plasmodium falciparum Erythrocyte Membrane Protein-1 (PfEMP1) is a potential malaria vaccine candidate due to its involvement in pathogenesis. Injection of DBL2β-PfEMP1 recombinant protein in animal models induces IgG and CD4+ production and inhibits binding with host endothelial receptors. This study aimed to analyze the spleen immune response by measuring the white pulp diameter. The experimental study used Wistar rats (Rattus norvegicus) that were divided into four groups, a control group and three treatment groups, which were injected with 100, 150, and 200 μg of DBL2β-PfEMP1 protein. Injection was done thrice with three-week intervals (days 0, 21, and 42). On day 56, rats were euthanized, and spleens were prepared for histology examination. The white pulp diameter increased along with increasing the dose of protein. The ANOVA test showed a significant difference between groups (p=0.001). The posthoc Bonferroni test showed a significant difference between the control and the 150 and 200 μg groups and the 100 μg and 200 μg groups. In conclusion, the DBL2β-PfEMP1 recombinant protein injection increased the spleen white pulp diameter in Wistar rats, and the 200 μg dose resulted in the highest increase.

This study was conducted at Mohammad Hoesin Hospital Palembang in October-November 2022. Cognitive decline was detected by examination of the Montreal Cognitive Assessment-Indonesian version (MoCA-Ina) while other variables were obtained through interviews. The data were analyzed with Chi-square or Fisher exact tests.
Age, education level, and age at hemodialysis initiation affect global cognitive function in CKD patients. In cognitive domain analysis, a significant relationship was found between age and duration of hemodialysis and attentional function, as well as the impact of age, sex, and age at hemodialysis initiation on executive/visuospatial function.
Several demographic and hemodialysis characteristics are associated with cognitive decline in hemodialysis patients. Education and periodic cognitive screening are necessary to prevent and detect cognitive decline in these at-risk populations.

Vaccination prevents infectious diseases and mother’s consent is key to increasing childhood vaccination rates. The aim of this study was to assess mothers' knowledge, and beliefs about childhood vaccinations, as well as the impact of these factors on their vaccination behaviors. A descriptive cross-sectional study of 320 mothers was conducted. The data were collected using a questionnaire form. Most of mothers (98.4%) have their children fully vaccinated through the Extended Immunization Program (EIP), 96.6% of cases support vaccines necessity. Vaccine hesitancy was 7.8%, vaccine refusal was 1.6%.  The majority of mothers believe that the most common side effects of vaccines are fever (53.4%). Mothers were not adequately informed about EIP were 42.2%, and 57.5% of them had not received non-EIP vaccines, and 33.1% cited lack of knowledge as the reason. The majority of cases (73.7%) received information about EIP from a doctor. Parents' educational status, higher family income, and having more than three children significantly increased non-EIP vaccination rates but had no significant effect on EIP vaccination (p<0.05). Mothers still support EIP, but vaccine hesitancy is growing due to a lack of information. It is critical to assess mothers' knowledge and beliefs about vaccination, and social awareness is also required.

To model a laboratory experiment for determining the wavelength of light using a diffraction grating in Python, it is proposed to use the libraries numpy, matplotlib, and ipywidgets. A simulation is created to model the positions of maxima on the screen. The developed code can be run in an environment that supports ipywidgets, such as Jupyter Notebook, to obtain an interactive simulation for determining the wavelength of light using a diffraction grating. The code includes the following steps: 1. Import the necessary libraries: numpy for numerical calculations, matplotlib for plotting graphs, ipywidgets for creating interactive widgets. 2. Define constants: d - the distance between the slits of the diffraction grating, L - the distance from the grating to the screen. 3. Create the function calculate_maxima to calculate the positions of the maxima. 4. Create the function plot_diffraction_pattern to plot the diffraction pattern. 5. Create interactive widgets: wavelength_slider to change the wavelength of light, order_max_slider to change the maximum order of the interference maxima. 6. Run the interactive simulation, which allows parameters to be adjusted and results to be observed in real-time.

A review of the current system for the health and development of children and adolescents in the Kyrgyz Republic revealed a number of key issues. There is a lack of coordination among public, private, non-governmental, and international organizations for the advancement of current condition of children and adolescents. The staff of the health care system, education, social protection and other government agencies, whose activities, one way or another, are related to working with children, need to improve their skills, taking into account the expansion of policies in the field of health protection and development of children and adolescents. There is limited use of available factual data to improve the quality of medical care, habilitation and rehabilitation, disease prevention (overweight and underweight, tuberculosis, diseases of the reproductive system, psycho-emotional disorders, etc.) violence, and trauma. Environmental risks remain high (clean water, safe environment and living conditions). There is very low participation of the civil sector in decision-making and implementation of a program in the field of health care and development of children and adolescents.

The study is devoted to the analysis of disability in children with cerebral palsy in the Kyrgyz Republic. Social impairment is typical for children with cerebral palsy, caused in most cases by multiple types of disability - restrictions on physical independence and mobility; ability to obtain an education, and master the basics of professional activity in the future, readiness for integration into society. In addition, there are problems about the impact of medical, demographic, socio-economic factors, as well as health care resources on morbidity statistics and the incidence of cerebral palsy. The article analyzes the activities of the rehabilitation center for children with musculoskeletal disabilities in the city of Osh for 2021-2023. In order to assess the quality of medical rehabilitation, an analysis and assessment of the medical history of the Center for Medical Rehabilitation from 2021-2023 was also carried out. The interviewing was carried out using a questionnaire specially developed by us, including 12 questions. When analyzing the medical history of children diagnosed with cerebral palsy who underwent medical rehabilitation at the center, it was revealed that the main causes of this condition are: birth injuries, intrauterine infection, premature birth, low birth weight, neuroinfection and severe meningococcal infection before the age of years, anemia, congenital malformations and various somatic diseases. The data obtained confirm the need to create a unified database of children with cerebral palsy (CP). This will improve the organization of medical and social rehabilitation of children suffering from cerebral palsy. The joint database will help collect information on the reasons, characteristics and effectiveness of various rehabilitation methods, which in turn will contribute to more effective management and care of this vulnerable group of children.
