Published: April 2023

Non-communicable diseases are responsible for 71% of the premature deaths worldwide. Unfortunately, 77% of those deaths occurred in the developing countries including Indonesia. In response, universities can provide potentially empowering health promoting programs for tackling the risk factors of non-communicable diseases. This study was aimed to explain the process of how to empower universities for tackling these non-communicable diseases’ risk factors through the Health Promoting University (HPU) program. This study was a descriptive study. The population included Indonesian universities that were involved in the HPU development program in 2019-2021 in collaboration with Universitas Gadjah Mada and The Ministry of Health Republic Indonesia. Sample subjects were the total population of 40 universities. Data were collected through unstructured observations, short interviews, and documents. Observations were performed in 25 universities. Meanwhile, unstructured interviews were conducted with 34 respondents. Data were analyzed descriptively. The process of the HPU development and the focus programs were varied. Many factors contributed to the process of the HPU development, such as the HPU development strategies, the university leaders’ commitment, networking, social capital, and participants’ capacity in the health promotion. According to the HPU development process from 2019-2021, the HPU development strategy performed in 2021 was the most structured and comprehensive. The capacity building, mentoring system, leader commitment, and networking strongly contributed to the success of the HPU development. This study emphasizes the importance of the university leaders’ awareness toward health and the potential resources of the university for tackling the risk factors of the non-communicable diseases.

Feature Selection for Loan Repayment Prediction System Using Machine Learning
Authors: Goyal Jishnu
Published: April 2023

Abstract: It is essential for banks to evaluate and predict the repayment ability of the loaners in order to minimise the risk of loan payment default. Due to this, there are systems created by the banks to process the loan request based on the loaners’ status, such as employment status, credit history, etc. This paper attempts to determine the most significant factors/features which help in predicting whether a loan applicant would be able to repay their loan. Feature selection provides an effective way to solve this problem by removing irrelevant and redundant data, which can reduce computation time, improve learning accuracy, and facilitate a better understanding of the learning model or data. In order to properly assess the repayment ability of all groups of people, several frequently-used evaluation measures for feature selection are applied, and different sets of features using different feature selection methods are generated. Afterwards, those sets are tested against different machine learning models, to figure out the most effective feature set that should be analysed in order to figure out the repayment ability of an applicant. The data used in this study was gathered from a Kaggle Dataset which contained the details of over 300,000+ loaners and whether they were able to repay their loans or not. After data cleaning and feature engineering, the dataset still appeared quite imbalanced , so, along with accuracy, other measures such as precision, recall, and F1 Score were also considered. Results of the study indicate that, days employed, number of family members , number of children , income of the person were some of the most significant factors for determining a borrower’s performance.

Authors: Jagan Inti , Harshavardhan Kurmapu , Rani Kancharapu Sharmila , Kavitha Karri , Krishna Killi Mohan
Published: April 2023

Abstract: Concrete is the most widely used material in the world for construction, more than any other commodity. It is also the second-most used material after water in the world. In concrete, aggregates are the most abundant component by volume and are naturally low in carbon, and the demand for natural coarse aggregate is increasing in construction activities. Using light aggregate materials as coarse aggregates can help reduce the environmental impact of construction projects. Lightweight aggregates in concrete have a low density, which gives it several other properties like low self-weight and good thermal and acoustic insulation. Coconut shells can also be used as a lightweight aggregate in concrete. Coconut shell, a natural by-product of the coconut industry and a renewable resource, is one potential lightweight aggregate. In this experimental investigation, coconut shells were used as a partial replacement for coarse aggregate in lightweight concrete at 0%, 10%, 20%, 30%, and 40% of the concrete mixes, whereas this paper presents practical work on mechanical properties such as compressive strength and split tensile strength in the concrete.

Evaluasi pemupukan cara benam dilakukan untuk mengetahui permasalahan yang dihadapi kebun dalam menerapkan kebijakan yang dimulai sejak akhir tahun 2019 di beberapa kebun kelapa sawit, khususnya penggunaan alat untuk membuat lubang pupuk. Hasil pengamatan menunjukkan bahwa pemupukan sistem benam telah dilakukan di kebun, dengan menggunakan mesin bor maupun alat manual, dengan kualitas pekerjaan yang beragam sesuai dengan ketersediaan mesin bor, kondisi lahan serta sumber daya manusia di setiap kebun. Mesin bor yang digunakan terdiri atas mesin bor tanah (MBT) dan mesin bor babat (MBB) yang telah dimodifikasi. Sementara alat manual terdiri atas pecok dodos, pecok pipa, pecok injak, dan cangkul digunakan untuk membantu membuat lubang pupuk mengingat terbatasnya jumlah dan kapasitas kerja mesin bor. Kebijakan untuk menggunakan mesin bor memerlukan komitmen yang kuat dari perusahaan dalam hal pendanaan secara berkelanjutan, mengingat penggunaan mesin bor memerlukan dana khusus untuk pengadaan, perawatan rutin, perbaikan, operasional mesin bor serta untuk premi pekerja terampil. Dalam kondisi pendanaan yang terbatas, pemupukan secara benam tetap dapat dilakukan secara selektif pada areal yang tingkat pencuciannya tinggi, yang dapat dilakukan menggunakan alat manual. Alat manual tidak memerlukan biaya khusus untuk pengadaan dan perawatannya, serta dapat digunakan oleh tenaga kerja tanpa perlu ketrampilan khusus.

In this study, 89 strains of Aeromonas hydrophila and 88 strains of Pseudomonas aeruginosa were isolated from the sewage of a university hospital in Turkey. The resistance of these bacterial isolates to 11 different cephalosporin classes’ antibiotics belonging to four generations and to 4 heavy metals was investigated. Cadmium, lead, manganese, and zinc are the heavy metals employed. There was a high incidence of resistance to cefazolin (98.9%), cefaclor (98.9%), and cefprozil (97.8%) among the A. hydrophila isolates. Lower resistance to cefoxitin (30.3%), cefepime (30.3%), and ceftazidime (31.4%) were found. Cefazolin, cefuroxime, cefaclor, and cefoxitin resistance was found to be (100%) among the P. aeruginosa isolates. Moreover, resistance rates to cefprozil (98.9%), cefixime (96.6%), and ceftizoxime (85.2%) were detected. No isolates of P. aeruginosa were showed resistance to ceftazidime, cefepime and cefpirome. Multiple antibiotic resistance (MAR) indexes ranged from 0.27 to 1.0 among A. hydrophila isolates and from 0.46 to 0.72 among P. aeruginosa isolates. All of the A. hydrophila and P. aeruginosa isolates showed resistance to cadmium. A. hydrophila and P. aeruginosa isolates showed low resistance to lead of 6.7% and 2.2% respectively. Results indicate that both species are easily recovered in hospital sewage and these species gained resistance to different generations of cephalosporins and heavy metals.

Authors: Iványi Tamás , Danyi Pál
Published: April 2023

Entrepreneurship lecturing and student engagement in large classes of university students are a constant challenge for lecturers. The purpose of our paper is to present the validation of a student segmentation method that has become very successful. We present methodological novelties applied in a Launch of Innovative Businesses course and the connecting multiple cross-sectional research. The course can be completed in three ways, meeting the needs of three student segments identified in the classes. The quantitative primary research is based on hierarchical clustering that was applied to questionnaire data of five semesters’ student responses. Results confirm the existence of these segments and that most of the students signed up on entrepreneurship courses have clear preliminary expectations of the course. The presented design framework can be generally applied in large and small classroom environments, and can also be reused as a proven case.
The semiotic functioning of synthetic media
Authors: Viidalepp Auli
Published: April 2023

The interpretation of many texts in the everyday world is concerned with their truth value in relation to the reality around us. The recent publication experiments with computer-generated texts have shown that the distinction between true and false, or reality and fiction, is not always clear from the text itself. Essentially, in today’s media space, one may encounter texts, videos or images that deceive the reader by displaying nonsensical content or nonexistent events, while nevertheless appearing as genuine human-produced messages. This article outlines certain problems with artificial intelligence (AI)-generated content, and frames the issue as a problem of recognising its proper referential reality. Examples include generative texts, deepfakes and their functioning in contemporary culture. The article makes use of the concepts of mimicry and nonsense to reveal the elements and counterparts in the communicative processes involving generated media.
Miniaturized 3-Bit Frequency-Reconfigurable Monopole Antenna with a Meander-Line
Authors: Hu Xueyang , Liu Yun , Yang Yueyou
Published: April 2023

A novel 3-bit frequency-reconfigurable antenna (FRA) with miniaturized
dimensions is realized with a meander line. The frequency
reconfiguration of the antenna is achieved by introducing N RF p-i-n
diodes into the meander line. The related parts of the meander line with
different lengths are bypassed or included into the antenna by switching
on or off the diodes, resulting in 2N switchable size lengths of the
antenna and equally spaced operating frequencies. A 3-bit meander-line
reconfigurable antenna (N=3) is designed, and the simulated and measured
results agree well. The antenna provides 23=8 independent switchable
states, with the operating frequencies covering a wide switchable
frequency range from 1.04 GHz to 1.51 GHz and the working bandwidths
varying from 80 MHz to 150 MHz. The number of working states is
optimally large, considering the number of switches used. Besides, this
work has an acceptable peak gain of 1.59 dBi regarding the miniaturized
total dimension of 0.17 λ × 0.07 λ (λ is the wavelength of the lowest
working frequency), which is more compact than many published FRAs.

Authors: Hanifah Dinar , Sitaresmi Mei , Hanifa Intan , Indraswari Braghmandita , Setyowireni Dwi
Published: April 2023

BACKGROUND: Behavioral and emotional problems (BEPs) affected a
significant proportion of preschool-aged children. The Covid-19 pandemic
may increase the prevalence and treatment gap. Therefore, assessing
determinant factors is needed to design appropriate prevention and early
interventions. This study aims to assess the prevalence of BEPs in
preschool-aged children in Indonesia and its determinant factors during
the Covid-19 pandemic. METHODS: We conducted a community-based
cross-sectional study in the Sleman District, Yogyakarta Special
Province, Indonesia, from July to August 2022. We recruited children
aged 2 to 5 and their parents using the Sleman Health and Demography
Surveillance System framework. We used the Early Childhood Screening
Assessment to detect BEPs in children and parents with a risk of
depression. RESULTS: We recruited 214 children and their caregivers. The
prevalence of BEPs in young children was 17.8%, and 16.8% of parents
have a risk of depression. Based on the multivariate regression
analysis, factors associated with BEPs are males adjusted OR 2.26 (95%
CI:1.01-5.08) and parents with a risk for depression adjusted Odds Ratio
5.11 (95% CI 2.21-11.81). CONCLUSION: Early detection and intervention
of BEPs in children and parents are essential to prevent mental illness
and improve well-being, especially during the Covid-19 pandemic.
Synergetic alkoxy side-chain and chlorine-contained end group strategy toward high performance ultra-narrow bandgap small molecule acceptors
Authors: Zou Yingping , Wei Qingya , Liang Songting , Qiu Beibei , Liu Wei , Xu Xiang , Fu Yuang , Lu Xinhui , Yuan Jun
Published: April 2023

Ultra-narrow bandgap (ultra-NBG) small molecule acceptors (SMAs) show
great potential in organic solar cells (OSCs) due to the extend-ed
near-infrared (NIR) absorption. In this work, a synergetic alkoxy
side-chain and chlorine-contained end group strategy is employed to
achieve A-DA’D-A type ultra-NBG SMAs by introducing alkoxy chains with
oxygen atom at the second position into the thiophene β posi-tion as
well as replacing the F atoms with Cl atoms in the end group. As a
result, the heptacyclic BZO-4F shows a redshifted absorption onset (960
nm) than Y11 (932 nm) without oxygen atoms in the side chains. Then, the
fluorinated end groups are substituted with the chlorinated ones to
synthesize BZO-4Cl. The absorption onset of BZO-4Cl is further
redshifted to 990 nm, corresponding to an optical ultra-NBG of 1.25 eV.
When blending with the polymer donor PBDB-T, the binary devices based on
PBDB-T: BZO-4F and PBDB-T: BZO-4Cl delivers power conversion
efficiencies (PCEs) over 12%. Furthermore, ternary devices with the
addition of BZ4F-O-1 into PBDB-T: BZO-4Cl system achieve the optimal PCE
of 15.51%. This work proposes a synergetic alkoxy side-chain and
chlorine-contained end group strategy to achieve A-DA’D-A type ultra-NBG
SMAs, which is important for future molecular design.

PlzA is a c-di-GMP-binding protein crucial for adaptation of the Lyme
disease spirochete Borrelia ( Borreliella)
burgdorferi during its enzootic life cycle. Unliganded
apo-PlzA is important for vertebrate infection, while liganded
holo-PlzA is important for tick acquisition; however, the
biological function of PlzA has remained enigmatic. Here we report that
PlzA has RNA chaperone activity that is inhibited by c-di-GMP binding.
Holo- and apo-PlzA bind RNA and accelerate RNA annealing,
while only apo-PlzA can strand displace and unwind
double-stranded RNA. Guided by the crystal structure of PlzA, we
identified several key aromatic amino acids protruding from the
N- and C-terminal domains that are required for RNA
binding and unwinding activity. Our findings illuminate c-di-GMP as a
switch controlling the RNA chaperone activity of PlzA and we propose
that complex RNA-mediated modulatory mechanisms allow PlzA to regulate
gene expression during both the vector and host phases of the B.
burgdorferi life cycle.

For this study, we focus on the exploration of maritime areas that
contain accident-prone points, such as illegal riding, unauthorized
boarding, illegal fishing, and smuggling. This exploration is carried
out using a cooperative system consisting of an Unmanned Aerial Vehicle
(UAV) and an Unmanned Surface Vehicle (USV). The goal is to allow the
USV-UAV system to efficiently explore all of the accident-prone points
while minimizing the UAV’s energy usage. Specifically, we aim to achieve
this objective while keeping travel time as short as possible. The
collaborative exploration system leverages the strengths of both the UAV
and the USV. The UAV is deployed to explore hazardous areas that are
inaccessible by the USV, while the USV doubles as a mobile charging
station, resolving the UAV’s energy limitation issue. The proposed
algorithm for this subject paper, called the Collaborative Accident
Searching Routing Optimization (CASRO) algorithm, utilizes the benefits
of both the Lazy Theta* algorithm and the Improved Ant Colony algorithm
to optimize the path of a cooperative system between USV and UAV. With
CASRO, we aim to address the two key limitations of the USV, namely poor
flexibility, and the UAV’s limited energy simultaneously. Finally, the
effectiveness and superiority of the proposed planning strategy in
target exploration is verified by numerical simulations of randomly
distributed maritime areas with accident-prone points.

Sperm morphology is considered a species-specific character and has been
used as a tool in the classification of numerous mammalian taxa.
Neotropical bats have been poorly studied, and important aspects on
sperm morphology have not been elucidated. The aim of the present study
was to describe and compare the sperm morphology and morphometry of
Molossus molossus and Molossops temminckii. 14 adults
specimens were analyzed from the Colección Mamíferos Lillo, Universidad
Nacional de Tucumán: five Molossus molossus and nine
Molossops temminckii. The epididymis were extracted and macerated
in Farmer’s solution, followed by a coloration with different stains. To
carry out the description and morphometric analysis, microphotographs
were taken under an optical, epifluorescence and scanning electron
microscope. A total of 50 sperm from each individual were measured for
morphometric analysis. The length and width of the head, midpiece and
tail were taken as variables. Sperm from M. molossus and M.
temminckii were practically identical, both morphologically and
morphometrically. In both species, a distal bulge was observed at the
end of the intermediate piece in a percentage greater than 85%. The
main characteristics shared between the species were: presence of
acrosomal blebs in the upper half of the head of the spermatozoa;
cephalic equatorial segment with filiform ornamentations; intermembrane
space of head apex wedge-shaped; helical middle piece and annulus at the
end of middle piece. In the present study, scanning electron microscopy
allowed us to visualize structures, such as acrosomal vesicles, that
were not detected with other types of microscopy.

The human head louse (Pediculus humanus capitis) is an obligate
ectoparasite of humans and has the potential to uncover aspects of human
history that cannot be directly inferred from genetic data derived from
humans. Previous studies have shown that global louse populations
exhibit restricted patterns of genetic variation. However, these studies
were restricted both genetically and lacked a global sampling. With the
aim of capturing the genetic diversity of head louse populations from
around the world, we generated whole genome sequences of human head lice
from 43 countries, spanning five continents and Oceania, to determine if
louse nuclear diversity mirrors its mitochondrial haplotypes or if
population genetic structure, genetic diversity, and population
connectivity are associated with geographical regions or host behavior.
Here we show that there are five nuclear genetic clusters that are
associated with large geographical regions, either at continental or
intercontinental levels. High genetic variation was found between
African and non-African individuals and the highest genetic diversity
was found in samples from sub-Saharan Africa, similar to that of humans.
Unlike the mitochondrial clades examined in previous studies, nuclear
genetic clusters of lice examined here are highly structured based on
geography (continentally and major regions within continents). Results
from our genome analyses revealed that host-mediated global dispersal as
the likely primary process in shaping diversity and maintaining genetic
population boundaries within the nuclear genome of the human head louse.
Psychological Impact of Poverty Alleviation through Resettlement Programmes: Special Reference to Young Adult Women Resettlers in Sri Lanka
Authors: Perera Niroshan , Karunathilake K
Published: April 2023

Resettlement as a poverty alleviation strategy is common in Sri Lanka.
Many local and international entities along with the government,
relocate poor people with better housing facilities and uplift their
living standards. Especially, providing a new housing unit with basic
facilities is making them a favorable atmosphere to nurturing a new
livelihood pattern, new social network system, access to market, access
for school and health facilities, etc. However, there are many negative
consequences of resettlement, particularly relating to the mental health
and psychological well-being of resettlers. It is also revealed that
women are more vulnerable to resettlement and experience many mental
health issues during and after resettlement. In addition, there are
several psychological impacts among the resettlers that have been
identified apparently. However, no detailed study to date has directly
focused on the main contributions to the mental health of women
resettlers in Sri Lanka. This study aimed to address said gap from a
sociological perspective with reference to popular resettlement models,
concepts, and other related frameworks. Particularly, this study is
focused in Kaluthara district of Sri Lanka. The study revealed that
resettled woman usually go through a transition period where she
experience emotional disturbances such as fear, anxiety and stress which
gradually reduces when she adjusts to the new environment, if
resettlement initiative assures,financial strength with better
livelihood opportunities and social recognition. Also, study findings
conclude how resettlers could experience mental and emotional
instability due to lack of essential facilities like proper sanitation,
efficient public services, better safety and security, corporative and
pleasant neighborhood etc.
A mysterious resistance to acenocoumarol!

Acenocoumarol is the most widely prescribed vitamin K antagonist (VKA)
to prevent and treat thromboembolic disorders. It keeps a major place in
many indications despite the introduction of new direct oral
anticoagulants (DOACs). However, a narrow therapeutic range, an
intra-individual variability and drug interactions may lead to serious
adverse drug reactions.  Sometimes, a genetic or acquired resistance to
this drug may lead to a risky situation. Hopefully, resistance to
acenocoumarol is a very rare phenomen.

Here in we present an unsusual case of a suspected resistance to
acenocoumarol. This case was notified to the Tunisian National Center of
Pharmacovigilance on October 2017 and registered under the number
2449/2017.

A 67-year-old patient with hypertension, diabetes, and coronary disease
was treated with captopril, atenolol, atorvastatin, and salicylic acid.
In 2017, acenocoumarol treatment was introduced. At biological control,
the prothrombin time (PT) was 100%. The doses of acenocoumarol were
raised progressively with iterative controls of PT. PT was always 100%
even when acenocoumarol reached the dose of 2 g/day. A resistance to
acenocoumarol was suspected. The patient was referred to
pharmacovigilance department for case analysis. During the patient
interview, we discover that the patient was confusing acenocoumarol with
atenolol. In fact, when his doctor was increasing the doses of
acenocoumarol, the patient increased her intake of atenolol believing
that it was acenocoumarol.

A resistance to acenocoumarol was eliminated in this patient since she
had never taken the drug. We highlight through this case the importance
of patient’s interview. Explaining the indications and the potential
adverse events of the drug to patients taking VKA is crucial to ensure a
better efficiency of treatment without increasing the risk of bleeding
complication.
Therapeutic Potential of Engineered Beige Adipocytes in Metabolic Diseases
Authors: Liao Yunjun , He Yufei , Cai Junrong
Published: April 2023

We sought to characterize the effects of engineered beige fat on
metabolic diseases by reviewing its history, examining experimental
data, exploring putative mechanisms of action, and predicting its
therapeutic future.White adipocytes are highly adaptable and can
transform into beige adipocytes with thermogenic capacity, which have
beneficial effects in treating metabolic diseases. However, access to
beige adipocytes is limited, and treatment efficacy decreases over time.
Thus, new approaches are needed to enhance the adaptive thermogenic
capacity of beige adipocytes. The investigation revealed that engineered
techniques, such as induction of stem cell regeneration, adipocyte gene
editing, and adipocyte reprogramming techniques, can generate beige
adipose tissue via autologous cell induction, adipose tissue remodeling,
and functional biomaterials. Engrafted engineered beige adipocytes can
generate large amounts of UCP1-positive adipose tissue in patients with
metabolic diseases, paving the way for developing metabolically active
beige adipose tissue and expanding its functionality in metabolic
therapy. Understanding how engineered beige fats treat metabolic
diseases will aid in disease prevention and treatment. These
sophisticated tissue engineering systems offer new avenues for
generating functional beige adipose tissue in patients with metabolic
diseases.
