Purpose
The outbreak of coronavirus disease (COVID-19) resulted in implementation of social distancing and other public health measures to control the spread of infection and improve prevention, resulting in a decrease in respiratory syncytial virus (RSV) and pediatric respiratory tract infection rates. However, there was a rapid and large re-emergence of RSV infection in Japan. Notably, we were faced with a difficult situation wherein there was a shortage of hospital beds. This study aimed to examine the epidemiological patterns of RSV-related hospitalizations among children before and after the COVID-19 pandemic onset at two pediatric emergency referral hospitals covering the entire Tokushima Prefecture.
Methods
Data were extracted from electronic medical records of children hospitalized with RSV infection between January 1, 2018, and December 31, 2021. All patients meeting the eligibility criteria were included in this study. The rates of study outcomes were documented annually during 2018–2021 and compared between the 2018–2020 and 2021 periods.
Results
In 2020, there was no RSV infection outbreak. In contrast, in 2021, RSV infection rate peaks were observed 1–2 months earlier than those in the previous years. Hospitalizations at the peak week in 2021 were 2.2- and 2.8-fold higher than those in 2018 and 2019, respectively. Hospitalizations in 2021 were concentrated within a short period. In addition, there was a significant increase in hospitalizations among children aged 3–5 months and those older than 24 months. Hospitalizations of children with siblings at home increased. The high-flow nasal cannula (HFNC) use rate nearly doubled in 2021.
Conclusions
A new pandemic in the future may cause an outbreak of RSV infection that can result in an intensive increase in the number of hospitalizations of pediatric patients requiring respiratory support, especially in infants aged < 6 months. There is an urgent need to improve the preparedness of medical systems, particularly in terms of the number of inpatient beds and the immediate availability of HFNC.

Published: January 2023

The analytical signal method and its derivatives can be explicitly calculated and assessed for analyzing and estimating the boundary of geological structures, such as faults or dikes, from potential field anomalies. Gravity field of the east of Qeshm Island and its north coast from Sarkhoun to Litadan in SE Iran has been measured in one-kilometer regular network. The regional anomaly effects are deducted from the Bouguer anomaly, where it can get the residual anomalies which is the considered dataset used in this study. The Bouguer range is 297 to 330 milligals (mGal) applying filters and modeling. It was revealed that there are five negative anomalies caused by salt penetration in the region. Regional anomalies expectedly have a low spatial frequency and long wavelengths, while the residual anomalies associated with shallow sub-surface potentials have high spatial frequencies and short-wave wavelengths. Two different fault trends were observed comparing the artificial model using MATLAB coding, the real one, and the filtered residual anomaly map of the Qeshm region. Also, another fault trend is suggested in the east height of Oman, which is a possible place of salt penetration. Due to the limited dimensions (120 * 100 km) and the information obtained from the existing drillings, the depth of the anomaly resources can be examined up to 8 km. Due to the gravitational condition between the two domes of Qeshm saline and the bridge located in the Hara saline area, it is suggested to be considered as an area for further oil exploration routines.

BackgroundAfrican swine fever (ASF) is a devastating disease of pigs that threatens the livelihood of smallholder pig farmers and the profitability of large-holder pig farmers. Outbreaks are attributed to human activities and practices along the pig value chain. Several outbreaks of ASF occurred in Nigeria in 2020. Hence a questionnaire survey was carried out with one hundred and thirty pig farmers and other stakeholders from 20 pig-producing states of the country on the pig value chain from the 8th– 21stof November 2020. This was to assess farmer knowledge of ASF and biosecurity practices carried out during their business along the pig value chain to suggest or improve control measures for the disease.ResultsThe result showed that 64.4% of the participants had experienced ASF outbreak in 2020. The univariate analysis by Pearson chi-square showed that participants had knowledge of ASF (OR: 9.632, p=0) and how disease spreads (OR: 2.464, p=0.02), and were both significantly (p<0.05) associated with the history of ASF outbreaks. In respect of practices, sharing farm implements (OR: 4.033, p=0.01) and mating boars with other farmers (OR: 2.73, p=0.01) were significantly (p<0.05) associated with the history of ASF outbreak. Logistic regression showed that participants involved with self-medication were three times more likely to have a history of ASF outbreak than those who did not.ConclusionsThe result showed that though stakeholders were knowledgeable about the causes and spread of ASF, they still had poor biosecurity practices that resulted in ASF outbreak in 2020 — implying that as long as the farmers do not practice good biosecurity, ASF outbreak will continue to be a challenge to the pig industry in Nigeria.

Published: January 2023

BackgroundIntestinal resection and a proximal stoma is the preferred surgical approach in patients with severe secondary peritonitis due to perforation of the small intestine. However, proximal stomas may result in significant nutritional problems and long-term parenteral nutrition. This study aimed to assess whether primary anastomosis or suturing of small intestine perforation is feasible and safe using the open abdomen principle with vacuum-assisted abdominal closure (VAC).MethodsBetween January 2005 and June 2018, we performed a retrospective chart review of 20 patients (> 18 years) with diffuse faecal peritonitis caused by small intestinal perforation and treated with primary anastomosis/suturing and subsequent open abdomen with VAC.ResultsThe median age was 65 years (range: 23–90 years). Twelve patients were female (60%). Simple suturing of the small intestinal perforation was performed in three cases and intestinal resection with primary anastomosis in 17 cases. Four patients (20%) died within 90-days postoperatively. Leakage occurred in five cases (25%), and three patients developed an enteroatmospheric fistula (15%). Thirteen of 16 patients (83%) who survived were discharged without a stoma. The rest had a permanent stoma.ConclusionsPrimary suturing or resection with anastomosis of an open abdomen with VAC in small intestinal perforation with severe faecal peritonitis is associated with a high rate of leakage and enteroatmospheric fistula formation.Trial registration:The study was approved by the Danish Patient Safety Authority (case number 3-3013-1555/1)and the Danish Data Protection Agency (file number 18/28404).

Published: January 2023

The availability of high spatio-temporal resolution of urban air temperature is paramount for understanding urban heat island (UHI) and developing effective mitigation strategies, in particular for local-scale mitigations. Obtaining high spatial resolution of air temperature at city-scale is challenging as the quantity of weather stations is often limited in cities, particularly in those less developed ones. In this study, based on the existing weather station network in Guangzhou city, China, we compare eight different air temperature interpolation models and select one with the best performance to interpolate city-scale air temperature. The training and validation of the models are performed using observatory meteorological data of 321 weather stations in Guangzhou. Deep learning-derived land cover information and social-economic data are encoded to be used as explanatory variables. The regression kriging combined with multiple linear regression is found to result in the best performance, with an average root mean squared error (RMSE) of 0.92℃ and a coefficient of determination (R2) of 0.959. Furthermore, the quantities and locations of current weather stations can be optimized by the proposed model. Guided by the k-means clustering alongside the information of geocoordinates and land cover, the number of current weather stations in Guangzhou can be reduced by 50% (i.e., 160 weather stations) while retaining the model performance. This study proposes and demonstrates an effective model for obtaining city-scale air temperature at high spatio-temporal resolution with data from sparse weather stations, which is much needed for cities which want to enhance their city-scale air temperature mapping by complementing new weather stations to their existing weather station network.
Obstacle based Anchor-FreeNodeLocalization in Under-Water Wireless Sensor Networks
Authors: Dass Ashish Kumar
Published: January 2023

Settle on the position of unknown sensors node called as localization process which is a serious concern in underwater wireless sensor network(UWSN) as it engross for different applications. As the anchor-based technique is expensive as well as very diminutive life-time researchers propose for anchor-free localization algorithms specially by designing a path for an Autonomous Underwater Vehicle (AUV) to maximize the location of accuracy as well as to reduce energy consumption. Many path planning proposals degrade their performance when there exist obstacles in the pathway of AUV. Hence, in this article we proposed a dynamic anchor free AUV based (DAFA) algorithm which determine the obstacle dynamically and change its path in accordance and the observed location of sensors node with accuracy in minimization of error, maximize the nodes settled and with minimum energy consumption. The simulation of the proposed model outperforms better than available traditional algorithms.

Published: January 2023

In order to tackle multifactorial illnesses, the importance of bioactive peptides in nano drug delivery systems is emphasised. Multifactorial diseases are primarily brought on by protein misfolding. Therefore, pharmaceutical formulations are recommended to deliver a successful treatment. Difficulties hinder its application in delivering raw peptides with poor bioavailability, absorption, and circulation time, making it a difficult assignment for researchers. Recently, bioactive peptides have become increasingly important in therapy. In addition, several bioactive proteins have poor absorption characteristics in the GIT. These issues can be resolved by creating nano-based peptide-based delivery systems that encapsulate, retain, protect, and transport bioactive peptides. The focus of the proposed review paper is to provide an overview of peptides, commercialization concerns, and their related attempts to develop into novel peptide-based nanoformulations.

Published: January 2023

Jaringan transmisi saat ini sudah menggunakan konfigurasi single Busbar dan double Busbar. Untuk konfigurasi pada GI Banyuwangi tidak semua penghantar dalam sistem tersebut sudah dalam konfigurasi double Busbar. Padahal dengan konfigurasi double Busbar menjadikan sistem tersebut lebih handal dan memiliki jatuh tegangan yang lebih rendah. Dengan laju pertumbuhan beban yang cukup tinggi khususnya di daerah Situbondo. Untuk menghindari adanya overload atau overcurrent ketika ada gangguan pada penghantar Banyuwangi-Situbondo yang dalam konfigurasi single Busbar, perlu adanya perubahan konfigurasi ke double Busbar. Hasil analisis load flow menggunakan ETAP dengan metode Newton Rhapson menunjukan bahwa beban yang melewati penghantar bus Banyuwangi mencapai 80 % dari beban maksimal. Ketika konfigurasi sistem dirubah dari single Busbar ke double Busbar, maka beban yang melewati penghantar bus Banyuwangi dan bus situbondo hanya 63.4%. Untuk bus Banyuwangi pada konfigurasi single circuit tegangan jatuhnya 21% dari tegangan nominalnya sedangkan double Busbar tegangan jatuhnya yaitu 14% dari tegangan nominalnya. Dari hasil analisis rugi-rugi daya menunjukkan total keseluruhan rugi-rugi daya untuk konfigurasi single Busbar sebesar 62.282 MW dan 191.619 MVAR untuk konfigurasi double circuit 44.038 MW dan 137.304 MVAR.

Analyses of the causes and the characteristics of poverty at micro levels provide more efficient strategies for the attainment of main Sustainable Development Goals. This study aimed to analyze the extent to which the characteristics of individuals, households, and communities influence the probability of household poverty status. The 2019 Social Welfare Integrated Data and Village Potential Data of Kediri City were analyzed using an ordered logit regression model and then interpreted based on marginal effect calculation. The study found that household headsâ€™ squared-age, household membersâ€™ education, household membersâ€™ occupation, household head gender (female), ownership of assets, access to the internet, access to proper sanitation, and access to financial institutions reduced the probability of households being categorized as very poor and poor. This finding indicated that household productivity influenced by the household headâ€™s characteristics in managing productive assets, supported by access to infrastructure, could increase the household's welfare. However, the household headâ€™s age and marital status, dependency ratio, and access to health facilities increased householdâ€™s probability of being very poor and poor. Policies regarding poverty must be adjusted to the poverty characteristics and status. Improving access, equalizing education, and improving job opportunity and infrastructure management that ensure accessibility and enhancement in service quality need to be made to increase the status of households with the lowest 40% welfare in Kediri City. Policies regarding poverty should be focused more on social programs for very poor and poor households. Meanwhile, those near-poor and vulnerable-to-poor need more empowering programs.

CAPITAL FLIGHT FROM NIGERIA: AN EMPIRICAL ANALYSIS
Authors:   School of Economics, Finance and Banking, Universiti Utara Malaysia, Hammed Oluwaseyi Musibau
Published: January 2023

The capital flight from Nigeria has become a trending macroeconomic issue within the country. This is as a result of its implications on economic growth due to the fall in investment as a result of scarce capital created by persistent capital flight. On estimates, Nigeria losses $22 billion to capital flight annually as a result of bad economic system alone; hence, the study analyzes the impacts of capital flight on Nigeria’s economic growth. The investment of portfolio theory is adopted in the study. This posits that an investor considers the real returns from investment in the determination of the detainment of wealth, or otherwise, in a country. Thus, the real interest rates differential has been identified as a main determinant of capital flight in an economy. This study employs the vector error correction mechanism (VECM) and granger causality test to analyze the causality between capital flight, interest rates differential, political instability and economic growth; using available data between 1980 and 2014. The results show that current year of capital flight is influenced by its previous year values, and there is a negative relationship between capital flight and Nigeria’s economic growth. Similarly, the results depict that a positive (and significant) relationship exists between capital flight and interest rates differential, explaining that the higher risk-adjusted returns abroad influence domestic capital flight. Also, there is unidirectional causality running from economic growth to capital flight; while there is independence among other variables.

The availability of green space is decreasing along with the increase in population. Since then the land has been replaced by buildings as more people need a place to support human activities. As a result, the absorption of heat increases, causing the temperature in urbanized areas are higher relative to outlying areas (Urban Heat Island). Therefore, some efforts need to be made to reduce heat absorption, one of which is by applying the green roof. A strong roof structure and roof panel are required to implement green roofs. Wood is a material that has both strength and lightweight. However, the use of wood panels for roofing is not common in tropical areas due to the high rainfall. The wood roofing still has a potential to be used through the application of green roof technology that accommodate a waterproof layer and is not easily degraded by planting media. This study aims to examine the potential use of green roofs which made of wood structures and wood roofing in a tropical climate.

This paper presents an experimental study on repairing damaged beam-column reinforced concrete joints using carbon fiber reinforced polymer (CFRP). The test objects were in the shape of the letter T which represented the beam-column connection. The test object came from the previous research which had been failure. The retrofitted action includes strengthening the column position, injection with concrete glue and adding CFRP. Two kinds of CFRP were use, CFRP sheets (EB) and CFRP strips (NSM). The integrity of concrete after injection were tested with Ultrasonic Pulse Velocity (UPV). The retrofitted specimens were tested in loading frame to occurred strength, stiffness and ductility for each kind of retrofitted action. Three kind of tested were held, bending in one direction, shearing in one direction, and quasi cyclic bending. The selection test adjusted to the damage history of specimen.

The need for housing in a metropolitan city such as Surabaya will increase with time. These needs can be met by building new houses or renovating. Sometimes the construction and renovation of houses will more or less have an environmental impact on the surrounding buildings. The case study in this paper aims to increase public awareness of the impact of construction project on the surrounding buildings. The case study was conducted by doing field observations on the location of a residential house construction which had an impact on the adjacent houses, located on the right and left side. It was obtained that the damage to the adjacent houses was caused by the demolition of the old building, the addition of loads, and the process of compaction of the backfill. Repair and strengthening of buildings must be carried out to restore the function of the building and prevent further damage. Unfortunately, repairing the building requires significant additional costs and causes the construction time to be longer.

Time, cost, and quality are three important elements of schedule that should be made in detail in order to assist in the evaluation of the project. In this research, we analyzed the acceleration of project completion duration. The case study on this research was taken in Tenggarong Seberang District and Tenggarong District. The method used in this research is the crash program method with the alternative implementation with a variety of added work hours and manpower, which are adding 1 hour, 2 hours, and 3 hours of work hours also the alternative of adding 25% and 50% of the manpower. This research aimed to determine the total time and cost of implementing the project after the crashed and determined the results of an optimal acceleration alternative by comparing the results of the analysis of the application of the crash program method. The work was accelerated (crashed) in this research is work that is on the critical path. The results of the application of the crash program method with the addition of working hours and manpower obtained an efficient acceleration alternative, namely the addition of 3 hours of working hours which resulted in the acceleration duration being 67 days or 25.56% faster than the normal duration of 90 days with a total acceleration cost of Rp 1,213,717,588.81 or 0.213% lower than the normal total cost of Rp 1,216,303,515.90.
The Literary Prestige of Censorship: The Case of Naked Lunch
Authors: Majewska Magda
Published: January 2023

By tracing the publication history of William Burroughs’ Naked Lunch, this article shows how the gate-keeping mechanism of censorship can facilitate literary prestige. The release of the Grove Press edition of Naked Lunch in 1966 after two obscenity trials marked the end of complete literary censorship in the US and was a crucial step towards the canonization of underground authors. By making it necessary to argue on behalf of the text’s form, the obscenity trials helped in framing Burroughs’s arguably “formless” text as both a coherent work and a work of high literary merit. The article offers a detailed account of the enabling role of censorship in the case of Naked Lunch, which consisted not only in generating the interest of underground publishers (Olympia Press in Paris and Grove Press in the US) but also in helping Burroughs’s formless, fragmented text take shape and as a novel.

Background

Individuals with type 1 diabetes represent a population with important vulnerabilities to dynamic physiological, behavioral, and psychological interactions, as well as cognitive processes. Ecological momentary assessment (EMA), a methodological approach used to study intraindividual variation over time, has only recently been used to deliver cognitive assessments in daily life, and many methodological questions remain. The Glycemic Variability and Fluctuations in Cognitive Status in Adults with Type 1 Diabetes (GluCog) study uses EMA to deliver cognitive and self-report measures while simultaneously collecting passive interstitial glucose in adults with type 1 diabetes.

Objective

We aimed to report the results of an EMA optimization pilot and how these data were used to refine the study design of the GluCog study. An optimization pilot was designed to determine whether low-frequency EMA (3 EMAs per day) over more days or high-frequency EMA (6 EMAs per day) for fewer days would result in a better EMA completion rate and capture more hypoglycemia episodes. The secondary aim was to reduce the number of cognitive EMA tasks from 6 to 3.

Methods

Baseline cognitive tasks and psychological questionnaires were completed by all the participants (N=20), followed by EMA delivery of brief cognitive and self-report measures for 15 days while wearing a blinded continuous glucose monitor. These data were coded for the presence of hypoglycemia (<70 mg/dL) within 60 minutes of each EMA. The participants were randomized into group A (n=10 for group A and B; starting with 3 EMAs per day for 10 days and then switching to 6 EMAs per day for an additional 5 days) or group B (N=10; starting with 6 EMAs per day for 5 days and then switching to 3 EMAs per day for an additional 10 days).

Results

A paired samples 2-tailed t test found no significant difference in the completion rate between the 2 schedules (t17=1.16; P=.26; Cohen dz=0.27), with both schedules producing >80% EMA completion. However, more hypoglycemia episodes were captured during the schedule with the 3 EMAs per day than during the schedule with 6 EMAs per day.

Conclusions

The results from this EMA optimization pilot guided key design decisions regarding the EMA frequency and study duration for the main GluCog study. The present report responds to the urgent need for systematic and detailed information on EMA study designs, particularly those using cognitive assessments coupled with physiological measures. Given the complexity of EMA studies, choosing the right instruments and assessment schedules is an important aspect of study design and subsequent data interpretation.
