Published: June 2022

Fraction as part-whole is the key to further fractional understanding, such as equivalent fractions. A problem faced by students in equivalent fractions is that they understand one part without including the other parts. This article discusses how 4th-grade students understand fractions as part-whole and equivalent fractions using units of equivalent. Indonesian Realistic Mathematics Education-oriented learning environment using jelly context was developed and tested in two stages, involving six students with different levels of mathematics ability. The analysis of group discussions and students’ answers to the given tasks shows that students with low abilities have difficulty showing that 1/4 is one part of the four parts. The students only know fractions in a/b form without understanding their meaning. It impacts the construction of equivalent fractions as units of equivalent. High-ability students can easily do mathematization on 2/8 or 2/6 by making a cut pattern before cutting the jelly. The research contributes to learning design that begins with activities related to the fractions as part-whole.

Published: June 2022

Highlights:

Patients with IRSS I stage have the longest lag time than IVB stage.
Lag time is no significant with stage retinoblastoma.

Abstract:
Retinoblastoma is a rare neoplasm disease that occurs in children, generally under the age of two. Retinoblastoma is more prevalent in developing countries and is often associated with a late diagnosis. Such delays can lead to a poor prognosis. The time from the appearance of symptoms of retinoblastoma (onset) to the time of diagnosis is called lag time. Early diagnosis of retinoblastoma by paying attention to factors such as age, clinical symptoms, and laterality can help improve retinoblastoma survival rates, especially in developing countries. The purpose of this study was to analyze the relationship between the lag time to the stage of retinoblastoma patients at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. This study was a retrospective analytical observational study using secondary data from retinoblastoma patients at the Ophthalmology Outpatient Unit at Dr. Soetomo General Academic Hospital, Surabaya, from January 2014 to December 2018. The data were analyzed using Kendall's tau-C test. No significant correlation was found between lag time and stage (p = 0.339). Patients with International Retinoblastoma Staging System (IRSS) I stage had the longest lag time (on average 28 months), and patients with stage IVB had the shortest lag time (on average four months). There was no correlation between lag time and retinoblastoma stage. However, there was a trend of patients with early stages delaying hospital visits, while patients with advanced stages in earlier to the hospital.

Published: June 2022

Highlights:

Sodium diclofenac is one of NSAID a common treatment to relieve pain associated with bone fractures.
Sodium diclofenac with a some dose of body weight could decrease the callus quality on fracture healing.

Abstract:
Non-steroidal anti-inflammatory drugs (NSAIDs), such as diclofenac sodium, are standard treatments to relieve pain associated with bone fractures. The bone healing process consists of four stages: inflammation, soft callus formation, complex callus formation, and bone remodeling. Previous studies mentioned that intake of NSAIDs (sodium diclofenac) could inhibit the bone healing process. This study examined the effect of diclofenac sodium intake on callus formation in fracture healing. In this study, thirty-six rats (Rattus Norvegicus) with fractures were used and divided into two groups, namely 18 rats for the control and 18 rats for the treatment group. In the treatment group, each rat was given 1.8 mg sodium diclofenac/150 grams of body weight per day. In the control group, each rat was given CMC-Na 0.5% with equal volume as diclofenac sodium in the treatment group. After 28 days, all the rats were stunned until dead, and the diameter and strength of their calluses were measured. In the treatment group with diclofenac sodium1.8 mg/ 150 grams BW/ 28 days after the tibia bone callus was pressed using the Shimadzu tool, the lowest callus strength was found to be 56.500 N, and the highest callus strength was 59.000 N. The lowest callus diameter in the treatment group was 4 mm, the highest was 5 mm. In the control group, the lowest callus strength was 76 N, and the highest callus strength was 77 N. The lowest callus diameter in the control group was 6 mm, and the highest was 8 mm. The strongest callus in the treatment group was found in the sixth observation, with a value of 59 N and a diameter of 4 mm. In the control group, the highest callus strength was 77 N, with a diameter of 7-8 mm. These measurements were found on the 5th, 7th, 8th, 9th, 16th, and 17th observations. Diclofenac sodium with a dose of 1.8 mg/150 grams of body weight could decrease the callus quality parameters, such as callus strength and diameter on fracture healing.

Highlights:

The strength of the relationship between respiratory dust levels and pulmonary function disorders could not be obtained.
The weakness level of correlation between years of service and pulmonary function disorders.

Abstract:
Environmental dust in the workplace exposes the workers as they are breathing. The dust is inhaled into the respiratory tract and causes occupational diseases in the form of pulmonary function disorders. Workers in the marble industry are also prone to dust exposure. This study aimed to analyze the correlation between years of service, respiratory dust levels, and pulmonary function disorders in marble home industry workers in Tulungagung Regency, Indonesia. This study was a descriptive observational study with data from a cross-sectional technique. The population was 18 workers taken as respondents. The independent variables in this study were years of service and the level of respirable dust, while the dependent variable was the pulmonary function disorders experienced by the workers. The data were analyzed using the Correlation Contingency test. There was a close correlation between years of service and pulmonary function disorders by 0.196, indicating that the relationship between those variables was weak. The strength of the relationship between respiratory dust levels and pulmonary function disorders could not be obtained because the constant results met the threshold value. The correlation between years of service and pulmonary function disorders was weak, and the relationship between respiratory dust level and pulmonary function disorders could not be obtained.

Published: June 2022

Highlights:

The combination of NLCR and PLR will improve the ability to distinguish infection rather than noninfection in the emergency setting for early antibiotic prescribing as well as the sepsis-3 strategy.
The diagnostic value of PLR in adult bacterial sepsis patients has never been studied.

Abstract:
According to Sepsis-3, antibiotics should be administered in the first hour of diagnosis of sepsis. Still, there is difficulty in differentiating between bacterial and nonbacterial infections and a lack of a rapid diagnostic tool to distinguish them. This study evaluated the diagnostic value of NLCR and PLR in suspected bacterial sepsis. The diagnostic value of PLR in adult bacterial sepsis patients has never been studied. This study was a retrospective study from the medical record of Dr. Hasan Sadikin Hospital Bandung. All patients at age ≥ 18 years diagnosed with sepsis based on ICD-10 code and qSOFA ≥ 2 were included. We calculated sensitivity, specificity, NPV, PPV, positive LR, and AUC of NLCR and PLR. There were 177 patients included in this study. The sensitivity of NLCR was 69.5%, specificity was 34.7%, NPV was 56.9%, PPV was 47.9%, and LR+ was 1.06, while the sensitivity of PLR was 62.2%, specificity was 38.9%, NPV was 54.4%, PPV was 46.8%, and LR+ was 1.02. We obtained cut-off values for NLCR 11.06, AUC 0.500, PLR 222.41, and AUC 0.497. The low value of AUC NLCR and PLR was due to prior antibiotic use. The combination of NLCR and PLR had higher positive LR (1.16) and specificity (54.7%), and also, according to NLCR, we had the highest sensitivity (69.5%). The combination of NLCR and PLR enhances the sepsis-3 strategy because it can be used as screening tools for bacterial sepsis, and antibiotics can also be administered in the first hour of managing sepsis, particularly in the emergency ward.

Published: June 2022

Highlights:

Uptake of hepatitis B birth dose vaccine within 24 hours of birth is low in Katsina, north-western Nigeria.
The most common reason for delay presentation for hepatitis B birth dose vaccine is maternal illness.

Abstract:
No studies focused on the hepatitis B birth dose (HepB-BD) vaccine since Nigeria adopted the strategy to reduce hepatitis B viral infection. Hence, we determined the uptake of HepB-BD, factors associated with timeliness, and those that contributed to delay. This study was a cross-sectional descriptive study carried out at an immunization post in north-western Nigeria. We recruited 400 mother-infant pairs that presented for the first immunization and obtained relevant information, including socio-demographics and reasons for the delays. Of the 400 infants, 44 (11.0%) received HepB-BD within 24 hours (timeliness), 105 (26.3%) and 274 (68.5%) by day 7 and 14, respectively. Multivariate analysis showed that mothers' education (primary adjusted odds (AOR) 17, 95% CI 1.404, 204.611), secondary AOR 5.9, 95% CI 1.148, 29.895), and tertiary AOR 7.7, 95% CI 1.228, 48.545), and third born AOR 8.2, 1.625, 41.018) were associated with HepB-BD timeliness. Maternal-related factors were the commonest (129; 46.6%) for delayed HepB-BD, with maternal illness the most commonly cited reason (37; 28.7%). This study showed a deficient level of uptake of HepB-BD vaccines among infants. Factors that were associated with timeliness included maternal education and higher birth order. The commonest reason for delayed HepB-BD was maternal illness.

Published: June 2022

Highlights:

Oxidative markers 8-Hydroxydeoxyguanosine and Nitric Oxide was found high in hemodialysis and non-hemodialysis chronic kidney disease patients.
There is no correlation between 8-Hydroxydeoxyguanosine and Nitric Oxide in hemodialysis and non-hemodialysis chronic kidney disease patients.

Abstract:
Oxidative stress is essential to chronic kidney disease (CKD). Several markers include 8-Hydroxydeoxyguanosine (8-OHdG) and Nitric Oxide (NO). Reactive oxygen species (ROS) and Reactive Nitrogen Species (RNS) increased in CKD and had a role in renal impairment progressivity. There are some controversies regarding oxidative markers in CKD patients in several studies. This study aimed to understand oxidative markers 8-OHdG and NO and explained the correlation of both markers in hemodialysis and non-hemodialysis CKD patients. Twenty hemodialysis patients and forty-nine non-hemodialysis patients were enrolled in this cross-sectional study. Urine patients were collected to measure 8-OHdG using the enzyme-linked immunoassay (ELISA) method, and NO was measured from serum patients using the Griss Saltzman method. Based on Bivariate Pearson analysis, there was no significant correlation between 8-OHdG urine and total NO serum in the hemodialysis group (p= 0,510, p>0.05) and in the non-hemodialysis group (p= 0.801, p>0,05). In this study, DNA oxidative marker, 8-OHdG, was not correlated with NO in CKD patients.

Published: June 2022

Highlights:

There is no correlation between the increase of SGOT and sepsis.
Correlation between the increase of SGPT and sepsis was significant founded.

Abstract:
Burns trigger hypermetabolic stress reactions that cause inflammatory responses. When there is a sustained or increased hypermetabolic reaction, the inflammatory response can be life-threatening, such as sepsis, and significantly impact hepatic metabolic function. After burns, varying degrees of liver injury are usually associated with burn severity. This study determined the correlation between elevated serum transaminases (SGOT/ SGPT) and sepsis in burn patients at a tertiary hospital of Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, from January 1, 2018, to December 31, 2020. This was a descriptive-analytic study with a retrospective cohort design. The data in this study included the demography of burn patients, causes of burns, inhalation trauma, burn severity, increased serum transaminase (SGOT/SGPT), mortality, and sepsis. This study found that the correlation between elevated serum transaminases (SGOT/SGPT) and sepsis was determined using the Spearman-Rho Rank statistical test. Burn patients with sepsis in the hospital were dominated by males (65.2%) and mostly aged 26-55 years (69.6%). The flame was found to be the highest cause of burns (80.4%), burn area above 20% (91.3%), the highest level of severity was major burn (91.3%), and no inhalation trauma (54.3%). In this study, there was an increase in SGOT of 69.6% and SGPT of 78.3%, with a mortality rate of 39.1%, with average inpatient days of 24 days. The correlation test between elevated serum transaminase (SGOT) and sepsis showed an insignificant relationship (p = 0.065, p> 0.05) with a correlation coefficient of 0.200. In contrast, the correlation between elevated serum transaminase (SGPT) and sepsis was significant (p=0.006, p<0.05) with a correlation coefficient of 0.296.

Highlights:

Workplace pollutants predispose people to hyperglycemia through beta cell dysfunction and insulin resistance.
The risk is increased by unhealthy lifestyles such as smoking and drinking.
Aging, due to mitochondrial function decline, also promotes hyperglycemia.

Abstract:
The increased global prevalence of hyperglycemia is linked partly to increasing industrial emission exposure, necessitating risk evaluations of various categories of workers worldwide. This study measured the blood glucose levels of selected non-obese artisans and workers from three companies (Imperio International, Mouka Foam, and Continental Iron) in Lagos, Nigeria. The participants’ demographic data were collected using structured questionnaires, after which their blood glucose levels were measured using a glucometer. The results were compared with the World Health Organization (WHO) standards (88–126 mg/dL). On average, Imperio International participants were 32 years old, Mouka Foam and Continental Iron were 28 years old, and the artisans were 32 years old. Most of the participants were male secondary school graduates who worked an average of nine hours per day, six days a week. Artisans had the highest hyperglycemic population (46.15%), followed by Imperio International and Continental Iron (33% each), and Mouka Foam (29.41%). Smokers accounted for 10.53% of the hyperglycemic population, followed by alcoholics (36.84%), those who drank and smoked (42.11%), and those who did not drink or smoke (10.53%). Age class ≥41 accounted for 36.84% of the hyperglycemic population, class 31-40 (34.21%), and class 21-30 (28.95%). Participants with secondary school education constituted 63.16% of the hyperglycemic population, primary education (18.42%), individuals having no education (13.16%), and tertiary education (5.26%). The findings indicate that workplace pollutants predispose workers to hyperglycemia and that smoking and alcohol increase the risks. The findings necessitate exposure reduction and healthy lifestyles in the workplace.

Nano- and microsatellites are becoming more and more popular in the last ten years. The main reason for this is the low cost of their development and launch. Two such satellites of the CubeSat format have already been developed at the Igor Sikorsky Kyiv Polytechnic Institute. They have successfully completed their missions in orbit. Work on a new satellite is underway. Before flying into orbit, all satellites must pass a large number of ground tests.
An important part of almost every satellite is its subsystem of orientation and stabilization. Since it contains magnetic sensors and electromagnets, special magnetic field simulators are used to test it. Such a simulator must create a uniform magnetic field with the required parameters. The most common design used to simulate a magnetic field is a Helmholtz cage. It was built in the nanosatellite laboratory of the Igor Sikorsky Kyiv Polytechnic Institute. This paper deals with the development of a control system for it.
In the beginning, the design, parameters, and operation principle of the Helmholtz cage were described. It consists of six electromagnetic square shape coils with a side of 1.5 meters. Each coil has 52 turns of 1.29 mm wire. Such dimensions make it possible to obtain a spherical zone of uniformity of the magnetic field with a radius of 293 mm. The control system should regulate the current in the coils, change its direction and also control the parameters of the generated magnetic field. The existing solutions for such a system were analyzed. As a result, it was decided to use an H bridge circuit and pulse width regulation.
The structural and schematic diagrams of the control system were developed. Were selected all necessary components, such as power module, central processing unit, microcontroller for PWM signal generation, and magnetometer for magnetic field control. To reduce the ripple of the output current, an RLC filter for the coil driver was developed. Its frequency response, current and voltage curves of its load were calculated analytically and coincided with practical results.
An experimental layout of the control system was assembled. As a result of the tests, it was found that the system regulates the current in the coil from 0 to 6.8 A and can change its direction. The current ripple in the coils does not exceed 1 mA (peak-to-peak) at an average current of 0,574 A. The duration of the transient in the system is about 23 ms. These values meet the requirements and allow simulating any mode of satellite flight in orbit.
The developed control system for the magnetic simulator allows testing the magnetic orientation systems of nanosatellites developed at Igor Sikorsky Kyiv Polytechnic Institute and will help in their preparation for the flight.
