Abstract
There is no doubt about the presence of iron sand around the west coast of West Sumatra. Several studies have been carried out, but in Ulakan Tapakis area is still under observation, and no investigation of its potential and distribution. One of the methods that can provide models and subsurface descriptions is using goelectrical resistivity method. The geoelectrical application in Ulakan Tapakis was used Wenner-Schlumberger array into 4 section. The section was designed perpendicular to the beach with a length of 47 meters for short lines and 470 meters for long line, the distance between sections was about 65 meters. The results obtained in the form of pseudosection types. Each section describes the distribution and lithology of rocks below the surface. The combination of all sections gives an overview of the iron sand model at Ulakan Tapakis. From the model obtained the results of geoelectrical measurements with the Wenner-Schlumberger array, the distribution of iron sand can be found along the coast of the study area at a depth of 0.7 m - 3 m in short line and 40 m in long line with resistivity values ranging from 52 - 289 Ωm

Abstract
Underground pipeline systems dominate today’s urban area landscape. This buried pipeline system will continuously develop along with the utility change. The planning for underground pipelines should be done to avoid mistakes in the pipeline path. Thus, mapping for the underground pipeline is necessary to obtain a database for any upcoming construction development. This research purpose is to detect underground pipelines around utility areas using the ground-penetrating radar (GPR) method. A frequency of 300 MHz was used to acquire GPR data from 6 lines, with a total length of 22.6m for each line and 0.5m for the line spacing. A sequence of processing stages of the GPR data was conducted using matGPR, a MATLAB-based program. Interpretable GPR profiles from each measurement line are obtained after adjusting signal position, removing DC, Dewow, mean filter, gaining, removing global background, and KL-filter. The results show an obvious amplitude reflection anomaly. Each line has similar detected underground pipes from its vertical axis, travel time, and horizontal distance. Clearly, all lines show an obvious contrast anomaly located at the 2.5 m horizontal distance. This most striking anomaly is interpreted as a water tunnel. In comparison, the other five parabolic-shaped anomalies were identified as underground pipes.

Abstract
Experiments are not only an essential component in expanding our knowledge but also play as a significant role in learning and teaching, especially in physics. Normally, some physics experiments are performed using specialize and expensive equipment. Due to the high cost, it is a major challenge financially to acquire, maintain and upgrade the equipment. These relatively expensive and specialize equipment make it difficult for many schools to be involved in laboratory work. Hence, students are deprived from performing some basics experiments, which are important in explaining the fundamental principal of physics. In order to create more conducive and engaging environment, we investigate the possibility of utilizing the PC sound card as sensors to determine the speed of sound directly. A special emphasis is given on easy to assemble experiments that can fit within the budget of any schools. The PC Sound Card and the utilization of Soundcard Scope overcome the technical difficulty to probe the time travel, t by sound in a short distance. Hence it enables us to determine the speed of sound directly by adopting the definition of speed. The result is compared with the experiment using Phyphox applications and resonance method. The speed of sound in air is found to be (340 ± 2) ms−1 as compared to the value measured using the echo method of Phyphox applications which is (341.2 ± 1.2) ms−1 and (340.6 ± 6.3) ms−1 using resonance method. Three selected experts in physics education have been involved to determine the validity of the experimental module while 31 trainee teachers from UPSI’s Physics Education Program have been engaged to study the usability of the experimental module using random cluster sampling techniques. It has been found that the agreement among the experts which is 100% for face validity and 98.33% for content validity. The finding from the usability study shows that all items obtained a high mean score value with a range of 3.55-3.90. Therefore, it is concluded that the technique and the experiment have a high potential to be used as a hand-on and an alternative method to directly determine the speed of sound in school.

Abstract
The purpose of this study was to analyze distance learning strategies in physics learning during the Covid-19 pandemic at Musamus University in the even semester of the 2020/2021 academic year. This study uses a quantitative descriptive method. The instrument used in this research is a questionnaire in a Google Form for the Physics Education study program students. The analysis results showed that as many as 34.4% of respondents said distance learning was effective. In addition, 62.5% of respondents said that distance learning was less effective, and 3.1% said it was ineffective. Distance learning is less effective because of many obstacles in its implementation. These obstacles are the lack of ability to use information and communication technology, inadequate internet network, and economic problems. Students also do not understand the concepts given during distance learning well because of the lack of assistance from lecturers. The implementation of learning is much more focused on providing materials, assignments, and scientific projects. These results indicate that distance physical learning during the COVID-19 pandemic has not been maximized.

Abstract
Physics learning aims to equip students with knowledge and ability to develop natural sciences. Very minimal learning resources become a problem in the learning process. Monotonous learning and the less effective learning model are factors of student saturation. The project based learning (PJBL) is one of the models used in making projects. The use of the PJBL in learning can increase student activity and creativity. In assessing project processes and outcomes in learning, an authentic and thorough assessment is required. This study aims to analyze the need for the PJBL model and portfolio assessment. The research method used is descriptive. The sample of this research is SMA/MAN teachers in 5 schools in Padang Pariaman. PJBL is very rarely used in learning because this learning model has its own difficulties in its implementation. The PJBL had a major impact in 3 schools, namely SMAN 12 x 11 Lingkung, MAN 1 Padang Pariaman, and SMAN 1 Lubuk Alung, with average scores above 60. Portfolio assessment has a great impact because it can facilitate students and teachers in the learning process. Results of this study are the teacher expects the ease of using the PJBL with the portfolio assessment of physics learning.
Relationship Between High Blood Pressure, Atrial Cardiopathy, and Mortality in the General Population
Authors: Imtiaz Ahmad Muhammad , Mendys Phil M , Kelly Scott P , Chen Lin Y , Soliman Elsayed Z 
Published: July 2022

Abstract

BACKGROUND
Atrial cardiopathy is associated with an increased risk of mortality. However, it is unclear whether this association is modified by hypertension, a risk factor for both atrial cardiopathy and mortality.

Methods
This analysis included 8,023 participants from the Third National Health and Nutrition Examination Survey. Electrocardiographic deep terminal negativity of P-wave in V1 ≥100 µV defined atrial cardiopathy. National Death Index was used to identify the date and cause of death. Cox proportional hazard analysis was used to examine the association of atrial cardiopathy with mortality among participants stratified by hypertension status.

RESULTS
In total 2.7% of the participants had atrial cardiopathy. Over a median follow-up of 14 years, 2,922 all-cause deaths occurred, of which 1,058 were CVD. All-cause death rates were almost double among participants with concomitant atrial cardiopathy and elevated blood pressure (BP) (120–129/&lt;80), stage 1 (130–139/80–89), or stage 2 hypertension (≥140/≥90) compared to their counterparts in the same hypertension stages without atrial cardiopathy (47.8, 61.3, and 80.2 vs. 23, 24.7, and 44.8 per 1,000 person-years (PY), respectively). In multivariable-adjusted models, a stronger association between atrial cardiopathy and all-cause mortality was observed in the presence compared to the absence of hypertension (HR (95% CI): 1.59 (1.25–2.01) vs. 0.67 (0.41–1.10), respectively, interaction P-value = 0.009). Similarly, an association between atrial cardiopathy and cardiovascular disease (CVD) mortality was observed in the presence compared to the absence of hypertension (HR (95% CI): 1.64 (1.08–2.47) vs. 0.63 (0.20–2.00), respectively, interaction P-value = 0.20).

CONCLUSIONS
Concomitant presence of high BP and atrial cardiopathy carries a higher risk of mortality, and the risk increases with higher BP levels.
Evaluating the Compartment-Specific Effects in Superficial Facial Fat Compartments After Thread-Lifts by the Tensiometer and FACE-Q
Authors: Kim Cheol Hwan 
Published: July 2022

Abstract

Background
The thread-lifts have been popularized because they offered minimally invasive procedures of facial rejuvenation, but not evaluated by the objective assessment system.

Objectives
The purpose of this study is to evaluate the compartment-specific effects after thread-lifts by the tensiometer and FACE-Q.

Methods
Retrospective cohort study was performed on 369 consecutive patients undergoing the thread-lifts with V-Loc devices (n = 173) and the limited scar face lifts (n = 196), with the mean follow-up period of 32.2 ± 5.2 months, between January 2014 and December 2015. Two hundred-seventy patients had intraoperative tension measurements performed. In an online survey, the blinded study coordinator registered all data in 12 FACE-Q scales.

Results
The average age was 46.0 ± 10.1 years. The complication rate was 4.8%. The mean value of the tensions was 9.5 ± 1.9 N. Patients were better satisfied with the appearance of their marionette (44.3 ± 24.8) lifted by device 3&4 (10.1 ± 1.6 N), compared with satisfaction with the appearance of their nasolabial folds (37.9 ± 20.7) lifted by device 1&2 (8.7 ± 2.1 N). The satisfaction of patients of the 40s and 50s&60s was higher than that of patients of the 20s&30s with decision. The satisfaction of patients undergoing limited scar face lifts was higher than that of patients undergoing thread-lifts with social and psychological functions.

Conclusions
The tension measurements correlate with compartment-specific effects and play the same role as the indicator between gravitational and volumetric theories, but the limited effectiveness of thread-lifts was found to look 2.3 years younger during a mean follow-up of 2.5 years.

Abstract

Background
It is unknown whether persons with symptomatic cryptococcal meningitis detected during routine blood cryptococcal antigen (CrAg) screening have better survival than persons presenting with overt meningitis.

Methods
We prospectively enrolled Ugandans with HIV and cryptococcal meningitis from December 2018 to December 2021. Participants were treated with amphotericin-based combination therapy. We compared outcomes between persons who were CrAg screened then referred to hospital with those presenting directly to the hospital with symptomatic meningitis.

Results
Among 489 participants with cryptococcal meningitis, 40% (194/489) received blood CrAg screening and were referred to hospital (median time to referral 2 days; interquartile range [IQR], 1–6). CrAg-screened persons referred to hospital had lower 14-day mortality than non–CrAg-screened persons who presented directly to hospital with symptomatic meningitis (12% vs 21%; hazard ratio, .51; 95% confidence interval, .32–.83; P = .006). Fewer CrAg-screened participants had altered mental status versus non–CrAg-screened participants (29% vs 41%; P = .03). CrAg-screened persons had lower quantitative cerebrospinal fluid (CSF) culture burden (median [IQR], 4570 [11–100 000] vs 26 900 [182–324 000] CFU/mL; P = .01) and lower CSF opening pressures (median [IQR], 190 [120–270] vs 225 [140–340] mmH2O; P = .004) compared with non–CrAg-screened persons.

Conclusions
Survival from cryptococcal meningitis was higher in persons with prior CrAg screening than those without CrAg screening. Altered mental status was the most potent predictor for mortality in a multivariate model. We suggest that CrAg screening detects cryptococcal meningitis at an earlier stage, as evidenced by a favorable baseline risk profile and notably fewer persons with altered mental status.

AbstractThe share of expenditure on medicines as part of the total out-of-pocket (OOP) expenditure on healthcare services has been reported to be much higher in India than in other countries. This study was conducted to ascertain the extent of this share of medicine expenditure using a novel methodology. OOP expenditure data were collected through exit interviews with 5252 out-patient department patients in three states of India. Follow-up interviews were conducted after Days 1 and 15 of the baseline to identify any additional expenditure incurred. In addition, medicine prescription data were collected from the patients through prescription audits. Self-reported expenditure on medicines was compared with the amount imputed using local market prices based on prescription data. The results were also compared with the mean expenditure on medicines per spell of ailment among non-hospitalized cases from the National Sample Survey (NSS) 75th round for the corresponding states and districts, which is based on household survey methodology. The share of medicines in OOP expenditure did not change significantly for organized private hospitals using the patient-reported vs imputation-based methods (30.74–29.61%). Large reductions were observed for single-doctor clinics, especially in the case of ‘Ayurvedic’ (64.51–36.51%) and homeopathic (57.53–42.74%) practitioners. After adjustment for socio-demographic factors and types of ailments, we found that household data collection as per NSS methodology leads to an increase of 25% and 26% in the reported share of medicines for public- and private-sector out-patient consultations respectively, as compared with facility-based exit interviews with the imputation of expenditure for medicines as per actual quantity and price data. The nature of healthcare transactions at single-doctor clinics in rural India leads to an over-reporting of expenditure on medicines by patients. While household surveys are valid to provide total expenditure, these are less likely to correctly estimate the share of medicine expenditure.
