Published: February 2022

Pusat Teknologi Satelit, Lembaga Penerbangan dan Antariksa Nasional (LAPAN) memiliki beberapa stasiun bumi yang tersebar di beberapa wilayah di Indonesia untuk mendukung pengoperasian satelit LAPAN. Stasiun bumi terletak di Rancabungur, Rumpin, Kototabang (Bukittinggi), Parepare, dan Biak. Semua stasiun bumi terhubung dan dilakukan pengontrolan secara terpusat dari stasiun bumi Rancabungur. Oleh karena itu diperlukan sebuah sistem pemantauan jaringan data yang mampu memonitoring kinerja  jaringan  setiap  saat.  Dengan  menggunakan metode  literatur,  dimana  penulis mencari beberpa referensi yang relevan dengan kasus-kasus yang ada, maka dibuatlah sistem ini yaitu dengan memanfaatkan paket Internet Control Message Protocol (ICPMP) dan Simple Network Management Protocol  (SNMP).  ICMP  merupakan protokol  jaringan internet  yang  berfungsi untuk memberikan kiriman pesan kedalam sebuah jaringan selama konektivitas. SNMP merupakan protokol dalam jaringan komputer yang dirancang untuk memonitor dan mengatur jaringan dari jarak jauh. Dengan menggunakan SNMP pengguna bisa mendapatkan informasi dan status perangkat jaringan yang digunakan. Dalam bekerja SNMP terdiri dari SNMP manager dan SNMP agent. SNMP manager bekerja untuk mengolah informasi dari perangkat jaringan yang di pantau. SNMP agent merupakan perangkat jaringan yang di monitor kinerjanya. Dalam penelitian ini SNMP digunakan untuk mengambil informasi mengenai memory dan storage dari jaringan stasiun bumi tersebut. Selain memanfaatkan protokol SNMP penulis juga memanfaatkan bot telegram yang digunakan untuk mengirim notifikasi kepada network administrator apabila terjadi gangguan pada jaringan. Sehingga dengan sistem ini kondisi jaringan data stasiun bumi LAPAN lebih mudah untuk dilakukan pemantauan karena network administrator bisa melihat kondisi memory dan storage dari komputer yang digunakan untuk operasi satelit, serta akan mendapatkan pesan melalui telegram apabila terjadi kendala pada jaringan data stasiun bumi LAPAN.

Penggunaan sistem informasi di perpustakaan sekarang sudah tidak asing lagi, dengan adanya otomasi sistem informasi terintegrasi yang dapat memudahkan dan meningkatkan kinerja seluruh elemen-elemen fisik maupun nonfisik. Proses yang berkaitan adalah seperti menyediakan informasi, mendukung operasi dalam proses registrasi, katalogisasi, pelaporan, pengolahan data anggota sampai proses peminjaman dan pengembalian koleksi buku beserta aturan-aturannya seperti lamanya peminjaman dan sanksi keterlambatan pengembalian buku. Pada saat proses pendaftaran anggota baru yang sedang berjalan masih dilakukan dengan secara manual dimana calon anggota harus mengisi formulir data di kertas yang diberikan oleh petugas perpustakaan untuk di bawa pulang dan melengkapi syarat-syarat yang diberikan. Kegiatan tersebut tentunya akan berdampak pada proses pelayanan yang memakan waktu dan biaya dikarenakan setiap masing-masing calon anggota diberikan lembaran kertas untuk proses pendaftaran. Dengan adanya sistem informasi pendaftaran ini diharapkan dapat mempermudah proses pendaftaran calon anggota perpustakaan baru. Melalui sistem informasi berbasikan website yang dapat di akses dari mana saja baik dari perangkat komputer maupun smartphone tentunya akan sangat mengurangi waktu dan biaya baik bagi calon anggota maupun pihak perpustakaan.

Published: February 2022

Las discusiones acerca del populismo evidencian que no es un fenómeno de la política que se origina en un país concreto ni tampoco que las democracias más consolidadas estén exentas de su presencia, pese a que lo consideran como un invitado incómodo. Los ejercicios de comparación entre países, casos y periodos distintos dan cuenta de que se pueden establecer elementos comunes en el sistema político, a manera de causas, las cuales explicarían la emergencia de líderes, partidos y expresiones del populismo. En este artículo, se contrastan los presidentes Daniel Ortega de Nicaragua, Nayib Bukele de El Salvador y el exmandatario Rafael Correa de Ecuador con la finalidad de explicar el contexto de su aparición en el sistema político de sus países.

Inland waters are very unstable ecosystems. They are affected by anthropogenic and natural activities. Consistent monitoring of the physico – chemical, nutrients and primary production parameters in surface water in Nigeria is vital to the management of the aquatic environment. However, information on the fluctuation patterns of physico – chemical parameters, nutrients and primary productivity of Gbalegbe River is limited. Therefore, the fluctuation dynamics of physico – chemical parameters, nutrients and primary productivity of Gbalegbe River, Delta State, Nigeria were investigated. Gbalegbe River (12.5 km) was spatially stratified into eight zones (S1, S2, S3, S4, S5, S6, S7, and S8) based on proximity to key anthropogenic activities. In each station, three sampling points were randomly selected. Temporal stratification covered wet (March - October) and dry (November – February) seasons. Water samples were collected from each station forth – nightly for 24 months following standard methods. Water samples were analysed for Dissolved Oxygen (DO, mg/L), Temperature (oC), Nitrate (Nitrate, mg/L – N), Sulphate (SO42-, mg/L), Magnesium (Mg, mg/L) and Gross Primary Production (GPP, gC/m2/d) using standard procedures. Data were analysed by using descriptive statistics and ANOVA at α0.05. The highest (4.52±0.56) and least (3.13±0.67) DO were obtained in S1 and S2, respectively. Temperature ranged from 24.28±5.84 to 28.45±2.06 in S3 and S2; Nitrate (1.07±0.03, 1.76±0.21) in S6 and S2, respectively. Temperature values were 27.55±1.60, 26.94±1.97; DO (5.75±0.73, 4.00±0.66) and Nitrate (1.05±0.64, 0.98±0.43) in dry and wet seasons, respectively. Sulphate ranged from 0.80±0.26 to 1.63±0.26 in S2 and S8; Mg (63.30±6.30, 67.51±4.95) in S7 and S1, while GPP values were 10.05±0.09 and 25.75±0.83 in S1 and S2, respectively. Seasonally, Sulphate ranged from 0.97±0.06 to 1.24±0.33; Mg (63.13±20.73, 65.94±6.01) and GPP (20.19±4.91, 35.34±6.37) in wet and dry seasons, respectively. The patterns of physico – chemical parameters, nutrients and primary productivity of Gbalegbe River are fairly unstable with DO, thus its rich fisheries resources could be threatened.

Women’s Access to Land and its Implications for Empowerment in Nigeria: The Case of Ilorin East Local Government Area, Kwara State, Nigeria
Authors:   Department of Agricultural Economics University of Ibadan Ibadan, Nigeria, Omomeji M. J , Olajide O. Adeola
Published: February 2022

There is a gender gap observed in access, ownership and control of land and other productive resources which is not in favor of women in Nigeria. While most studies on access to land resource have related it to food security, this study however examined its implications for the empowerment of women in the study area. Multistage sampling technique was used to obtain a sample of 120 households from the population. Questionnaires were used to elicit information from the sample, and its administration was interactive. Multiple linear regression analysis was used to examine the relationship between women's empowerment and access, control, and ownership of land resource. The regression analysis showed that land ownership, rights to land, and decision-making power over land had significant effects on the empowerment status. The study recommends that laws that will ensure and protect women's access and rights to land should be put in place and such laws should be properly monitored and evaluated.

Published: February 2022

The identification of mild fetal ventriculomegaly prompts further evaluation
focused on determining whether additional structural anomalies, genetic
abnormalities or congenital infections are present. The aim of this study is
to evaluate the frequency of chromosomal aberrations in fetuses with
isolated mild symmetrical ventriculomegaly and determine the risk for a
fetus with isolated mild ventriculomegaly to have chromosomal abnormality in
a back ground. Additionally, we have performed an evaluation of the
chromosomal microarray findings in a series of five fetuses with isolated
mild symmetrical ventriculomegaly and a normal karyotype. The retrospective
observational study included karyotype evaluation of 102 fetuses with
isolated mild symmetrical ventriculomegaly identified at the time of the
routine midpregnancy scanning. In five cases array-CGH was performed and the
obtained data were compared with the data in the bioinformatics databases.
Among fetuses with isolated mild symmetrical ventriculomegaly chromosome
aberrations were found in 2 (1,96%) fetuses. In both cases autosomal
aneuploidy was detected, and those are trisomy 21 and trisomy 18,
respectively. The finding of a mild symmetrical isolated ventriculomegaly on
the routine ultrasound fetal exam in the second trimester had low
sensitivity, but high specificity and negative predictive value in the
prediction of chromosome anomalies. Copy number variants
(microduplications/microdeletions) were detected in four cases (80%). A
search for the similar variants in NCBI ClinVar, DECIPHER, OMIM and ENSEMBL
data bases, revealed that the microdeletions/microduplications detected in
four fetuses in our study cannot be related with ventriculomegaly
development. Our findings suggest that karyotyping is not justified in
fetuses with isolated mild symmetrical ventriculomegaly (10-15 mm), in a low
risk population. Therefore, when mild fetal ventriculomegaly is found in a
low risk population, additional non-invasive procedures for chromosome
aberration screening (such as noninvasive prenatal screening based on
cell-free fetal DNA) are recommended, before making the decision to perform
invasive diagnostic procedures.

Published: February 2022

Sunflower (Helianthus annuus L.) is one of the most important crops grown in
the world, but it can be attacked by more than 30 different pathogens. The
areal of Macrophomina phaseolina (Tassi) Goid., one of the sunflower
pathogens nowadays often found in temperate regions, has been spreading over
the last few years due to climate change. The most effective eco-friendly
method for controlling charcoal rot caused by M. phaseolina is growing
resistant sunflower cultivars. Due to that, 24 commercially available
hybrids and 70 inbred lines were tested for M. phaseolina tolerance in a
two-year trial. Under the field conditions, two different inoculation
methods were used - the Unwounded Stem Base Inoculation (USBI) and Toothpick
(TP) method. This study identified five highly tolerant hybrids and 12
inbred lines that can be used in breeding programs for improvement of future
genotypes. Sunflower genotype screening tests for Macrophomina tolerance
indicated that both inoculation methods should be applied together to
provide reliable results, and that stem lesion length is a reliable trait
for disease severity assessments.
Assessment of fruit flesh browning in ‘Amasya’ apple cultivar and its two selected sibs
Authors: Atay Ayşe
Published: February 2022

Post-cut internal flesh browning of apples is a major limitation to consumer
acceptability as it causes to the unattractive appearance and consequential
off-flavour for fresh fruit. The browning of apples is also essential for
processed products such as fresh-cut, fruit juice, canned, frozen, and
drying. In this work, internal flesh browning susceptibility was
investigated in ?Amasya? apple cultivar and two superior sibs (named ?109?
and ?120?), of which female parent is ?Amasya?, for both visually and
objectively. Colour parameters of the cutting surface were measured every
ten minutes during the first thirty minutes after slicing. The most rapid
initial browning of fruit flesh occurred within the first ten minutes after
the disruption in both sibs and ?Amasya?. It was observed that ?Amasya?
undergone significant colour change first, followed by ?120? in all the
studied colour parameters, whereas ?109? did not brown significantly. Hence,
it can be concluded that ?109? could be useful in the fruit processing
industry thanks to the remarkable post-cut anti-browning properties.
Valuable correlations were found between pH and the colour parameters of
cutting surface in the thirty minutes after slicing. However, the colour
change parameters were not or weakly correlated to other fruit attributes.
The results of this study show the importance of the internal flesh quality
of fruit in breeding programs to maintain quality.

Published: February 2022

Maize is one of the most important crop species worldwide, but also extremely
susceptible to the effects of increasingly higher temperatures and drought
during the summer and its flowering and grain filling stage. Different
strategies are being utilized to ensure a satisfying yield potential and
quality even in the extremely unfavourable environmental conditions, which
are the result of climate change. Some of them are cropping pattern changes
and sowing alterations, including earlier sowing. Since this implies the
exposure to suboptimal temperatures during early developmental stages, it
leads to a demand for developing maize lines tolerant to low temperatures
during these stages. This research focuses on the first phase of
germination, imbibition. Maize tolerance to low temperatures is a complex
trait that includes different mechanisms and strategies that all work
together to ensure adaptation and survival, such as cell membrane changes,
antioxidative system activation, etc. Additionally, the low temperature
response of different maize inbreds varies substantially, so recognizing the
different ways in which they respond to low temperatures during imbibition
and other earlier stages of development is crucial. To accomplish this,
seeds of two maize inbred lines of contrasting susceptibility to low
temperatures were selected and exposed to control (20? C) and low
temperature (8?C) conditions during the first 24h of imbition and then
further analyzed to assess their response. This included germination and
tetrazolium assays; ascertaining membrane integrity by evaluating cell
leakage and lipid peroxidation; determining the antioxidative capacity by
assessing superoxide dismutase (SOD) and catalase (CAT) activity; and
expression analysis of four genes included in the low temperature response
(gibberellin insensitive dwarf 1 gibberellin receptor, gid1; fatty acid
desaturases 2 and 6, fad2 and fad6; plastid-lipid-associated 2 protein,
pap2). The results showed that, while there is not a significant difference
in their germination rate, they differ in their survival rate, with more
seeds of the tolerant genotype surviving the low temperature period.
Significant differences between them were found in cell leakage (p<0,01), as
well as gid1(p<0,05) and fad6 (p<0,05) gene expression assays. The present
research brings light to our understanding of the effect of low temperatures
on the first germination stage, - imbibition. It highlights the importance
of choosing the right inbreds for earlier sowing and points to certain
routes that could be taken for improving and accelerating the breeding
process for low temperature tolerance.
Association of rs1294845152 in CRISP2 with male infertility: RFLP and DNA sequence analysis
Authors: Zanganeha Fahimeh , Sheidaib Masoud
Published: February 2022

Infertility is a major health human problem with 10% to 15% of world-wide
occurrence. It may happen due to various reasons including physiological,
environmental, social, and genetic factors. Recent genetic investigations
show that hundreds of genes may act on infertility, each with minor effects.
Asthenozoospermia is one of the common types of infertility in men which is
determined by sperm motility reduction. CRISP2 gene is located on acrosome
and tail of sperm and plays crucial role in spermatogenesis, regulation of
sperm flagellum motility, acrosome reaction and gamete fusion. In general,
heterogeneous results are present for association of CRISP2 gene with
asthenoteratozoospermic male infertility, therefore, we carried out a
starting investigation to show association of rs1294845152 of CRISP2 Gene
with male infertility by RFLP analysis. We also tried to identify the known
SNPs and variant nucleotides adjacent to this SNP by sequencing. The present
study revealed that neighther rs1294845152, nor the neighboring sequences
show any association with this kind of male infertility in the limited
samples studied in Iran. In general, it seems that this part of men genetic
material shows a high degree of conservation and very low level of
nucleotide variability.
Optimised feature selection for early cancer detection

Published: February 2022

Global Cancer Incidence, Mortality and Prevalence (GLOBOCAN) status report
for the year of 2020, suggests the occurrence of 10.0 million cancer deaths
and 19.3 million new cancer cases. Clearly, cancer incidence and mortality
are rapidly growing worldwide. Also, the leading causes of cancer deaths are
found to be lung cancer and breast cancer. Cancer cells are having the
probability of spreading to other parts of the body too. Most chronic
cancers are not curable, but some can be controlled for a few months or
years. Also, there is a possibility of high rate of relapse of the disease.
These remissions can be partial or complete. But, if detected early, certain
cancers can be treated by surgery, chemotherapy, and radiation therapy. This
research work focuses on detecting cancer in its early stage so that right
measures can be taken to combat the disease. In this attempt to create a
beneficial working model, the combination of Artificial Neural Network
(ANN), Convolution Neural Network, Graph based Neural Network with Genetic
Algorithm (GA) have proven to be successful. As a proof of concept, we
present a combination of feature selection techniques that can effectively
reduce the feature set and optimize the classification techniques. The
proposed method, when applied on a benchmark dataset, gave a higher accuracy
by selecting most relevant 7 features out of 10 with an accuracy of 95.7%.
Using Convolution Neural Network, the accuracy improved to 98.3% with
optimal hyperparameter tuning.
Inter-simple sequence repeats genetic relationships between populations of Consolida (Ranunculaceae)
Authors: Meng Kuanhong , Yao Jia , He Congying , Farshadfar Mohsen
Published: February 2022

In fields like ecology, biogeography, conservation biology, and
macroevolutionary theory, species are considered as the fundamental unit of
study. Gray (1821), an expert on British flora, regarded the genus Consolida
to be a distinct genus based on a single species (C. regalis). Consolida, on
the other hand, is believed by some scholars to be a part of Delphinium.
There are no reports on the genetic diversity, modes of divergence, or
dispersion patterns of the various Consolida species that grow in Iran
despite their widespread distribution. Hence, a combination of atomic (ISSR
markers) and morphological examinations of 78 increases from seven species
of Consolida were conducted. One goal of this work is to determine the
diagnostic usefulness of ISSR markers in the delimitation of Consolida
species, another is to determine the genetic structure of these taxa, and a
third is to look at the relationships between species within these groups.
It was discovered in the current research that combining morphological and
ISSR data may help identify species. Analysis using AMOVA and STRUCTURE
found that the species of Consolida are genetically distinct, yet have some
common genes.

Identification of QTLS for yield and contributing traits in maize-teosinte derived bils under diseased-stressed and control conditions
Authors: Adhikari Sneha , Joshi Anjali , Kumar Amarjeet , Singh Kumar , Jaiswal Prakash , Jeena Singh , Pant Usha
Published: February 2022

In maize, grain yield is the most important trait having a complex
inheritance pattern. Yield contributing traits are more stable and have
higher heritability than yield. Therefore, the present study was conducted
to identify quantitative trait loci (QTLs) associated with grain yield and
its components by using simple sequence repeat (SSR) markers. A population
of 169 BC1F5 lines was derived from the crossing between maize inbred line
DI-103 and teosinte-parviglumis was utilized for genotyping and phenotyping.
In diseased stressed condition (E1), ear length (EL), ear diameter (ED),
kernel rows per ear (KR/E), kernels per row (K/R), test weight (TW), and
grain yield per plant (GY/P) had 7, 6, 7, 4, 6 and 5 QTLs whereas, in
controlled condition (E2) 5, 2, 5, 4, 5 and 3 QTLs were detected for
enlisted characters, respectively. Consistent QTLs across the environments
were detected for 5 of the 6 investigated traits and number of QTLs were EL
(2), ED (1), KR/E (3), TW (1), and GY/P (1) whereas, for K/R none of the
QTLs were common between E1 and E2. By mapping analysis, we have identified
genomic regions associated with two traits in a manner that was consistent
with phenotypic correlations among traits, supporting either pleiotropy or
tight linkage among QTLs. Three co-localized QTLs were identified between
grain yield and contributing traits. Notably umc1720-linked QTL at bin 4.10
was simultaneously responsible for GY and EL, ED, KR/E, K/R; umc1215-linked
QTL at bin 6.03 was simultaneously responsible for GY and ED, KR/E, K/R, TW;
umc1279-linked QTL was responsible for GY and ED, TW. The findings suggest
that the chromosomal region containing co-localized QTLs governing multiple
yields associated traits are potential targets for selection. In addition
for 6 studied traits, 44 superior lines were identified, and along with both
the parents i.e. maize (DI-103) and teosinte they were clustered in 11
groups. Therefore, lines clustered independently can be utilized in a
hybridization programme for the accumulation of yield contributing traits
for yield maximization.

Considering the importance of lymphoma and its prevalence in communities as
well as its relationship with genetic factors (P53 & MDM2) as well as
contradictory results about the possible role of deletion/insertion of
polymorphisms in different types of cancer. The aim of this study was to
investigate the deletion/insertion of 40 bp of mdm2 polymorphism and 16-bp
of p53 polymorphism in patients with lymphoma. In this case-control study,
152 non-Hodgkin's lymphoma patients and 155 healthy individuals were
selected by convenience sampling method. MDM2 and P53 polymorphisms were
examined by PCR. SPSS V22 software was used to interpret the results. The
results of the study showed that rs3730485 species was associated with the
risk of lymphoma. The Ins / Del and Del / Del genotypes reduce the risk of
lymphoma compared to the Ins / Ins genotype (OR = 0.41,95% CI = 0.25-0.65 P
<0.001 and OR = 0.33.95% CI = 0.12). 0.96, P = 0.035 In relation to Ins /
Del + Del / Del and Ins / Del, the results also showed that they reduce the
risk of lymphoma (OR = 0.40,95% CI = 0.25-0.63, P <0.001). Results indicated
that Ins / Del, Del / Del, Ins / Del + Del / Del and D alleles genotypes had
a statistically significant relationship with lymphoma risk. Due to the fact
that the OR genotypes of this site are less than one step away, it is a
protective factor for lymphoma, so that these alleles and the mentioned
genotype reduce the risk of lymphoma.

Published: February 2022

Nickel (Ni) is an essential nutrient for animals and it has an important role
in many physiological and biochemical processes in higher plants. At the
same time, it belongs to the group of potentially toxic elements (PTEs). The
aim of this study is to determine Ni concentrations in the soil-plant
relationships between the main crops and agricultural land in Central
Serbia. A total of 71 bulked soil samples are taken from the topsoil at the
depth of 0-30 cm in an area belonging to 6 statistical districts of Central
Serbia. A total of 71 seed samples are collected during harvest as an
average sample of seed from each observed plot, of which 26 are corn, 19
sunflower, 17 wheat, and 9 soybean samples. Analysis of the collected
samples includs the main soil parameters and Ni total and available
concentrations in soil, as well as Ni total concentration in seeds. The
median value of total Ni concentration in soil is 44.8 mg kg-1, close to
MAC. The median nickel concentration in wheat and corn seeds is 0.5 mg kg-1,
while soybean and sunflower seeds have higher median Ni content of 8.40 and
10.26 mg kg-1, respectively. Bioaccumulation factors in seeds (BAF) in the
present study ranges from 0.013 (corn) to 0.256 (soybean). According to
statistically significant differences, all crops have equal total NiT
concentration in soil, while the available NiA concentration differs in
soils under corn and sunflower cultivars. Based on Ni concentration in seed
and BAF, two groups are distinguished ? the group of soybeans and sunflowers
with higher Ni content and the group of wheat and corn with lower Ni content
in seed. The obtained differences confirm that plant species have a
significant role in the bio?accumulation of Ni. The determined BAF parameter
is in a statistically significant negative correlation with the total Ni
content in soil in all observed crops except maize. However, the BAF
parameter for maize alone is in a statistically significant negative
correlation with the readily available Ni concentration in the soil. The
obtained correlations indicate that higher Ni concentration in soil causes
lower Ni concentration in seeds, which might be due to the activation of
plant defense mechanism to preserve the reproductive organs ? seeds ? from harmful
effects. Based on the obtained results, Ni concentration in seeds of the
main field crops in Central Serbia is safe for feed and food usage. Increased content
of Ni found in agricultural soils in Central Serbia requires constant

OBJECTIVE

Maternal glycemic dysregulation during pregnancy increases the risk of adverse health outcomes in her offspring, a risk thought to be linearly related to maternal hyperglycemia. It is hypothesized that changes in offspring DNA methylation (DNAm) underline these associations.

RESEARCH DESIGN AND METHODS

To address this hypothesis, we conducted fixed-effects meta-analyses of epigenome-wide association study (EWAS) results from eight birth cohorts investigating relationships between cord blood DNAm and fetal exposure to maternal glucose (Nmaximum = 3,503), insulin (Nmaximum = 2,062), and area under the curve of glucose (AUCgluc) following oral glucose tolerance tests (Nmaximum = 1,505). We performed lookup analyses for identified cytosine-guanine dinucleotides (CpGs) in independent observational cohorts to examine associations between DNAm and cardiometabolic traits as well as tissue-specific gene expression.

RESULTS

Greater maternal AUCgluc was associated with lower cord blood DNAm at neighboring CpGs cg26974062 (β [SE] −0.013 [2.1 × 10−3], P value corrected for false discovery rate [PFDR] = 5.1 × 10−3) and cg02988288 (β [SE]−0.013 [2.3 × 10−3], PFDR = 0.031) in TXNIP. These associations were attenuated in women with GDM. Lower blood DNAm at these two CpGs near TXNIP was associated with multiple metabolic traits later in life, including type 2 diabetes. TXNIP DNAm in liver biopsies was associated with hepatic expression of TXNIP. We observed little evidence of associations between either maternal glucose or insulin and cord blood DNAm.

CONCLUSIONS

Maternal hyperglycemia, as reflected by AUCgluc, was associated with lower cord blood DNAm at TXNIP. Associations between DNAm at these CpGs and metabolic traits in subsequent lookup analyses suggest that these may be candidate loci to investigate in future causal and mediation analyses.
No More Kidding about iKids

If COVID-19 has taught us anything, it’s that even students born in the 21st century are not quite the digital natives we give them credit for being. Whilst the overarching concept of the digital native as proposed by Prensky in 2001 has been hotly contested for many of its generational assumptions over the last 20 years, it’s clear anecdotally that until recently, many still believed that students of the 21st century are very comfortable with technology and how it is used.

It’s only in the last few years, as the pandemic has forced learning online, that we’ve realized that perhaps students digital skillset might not be what we think it is. What’s more, stories abound of students turning cameras off, or behaving inappropriately in chat, that suggest that the problem is wider than skills, and a more holistic view of what it means to be a digital citizen is needed.

This presentation will take time to understand this trend towards digital citizenship, and what it means for us as scholars of technology enhanced learning. Looking back on past practices, it will make the argument the digital citizenship going forwards need to encompass more than just skills and needs to be more holistic in focus. In doing so, we can really understand how we might construct our curriculum into the future.

First, this presentation will break down the way we’ve traditionally thought about digital skills (Sturgess, Cowling, & Gray, 2016). Building on recent research, it will help understand what competencies need consideration in this space going forward, and how skills such as social networking or messaging might translate into our classroom.

It will then discuss screen time, and how students approach this aspect of digital citizenship (Orlando, 2021). Rather than talking about banning technology and removing it from classrooms, we will discuss how technology can be used to enhance the classroom experience, whilst also ensuring that students do not get addicted to using it inappropriately. Thoughts on how best to build balanced digital citizens will also be shared.

Concepts of digital safety will also be discussed (Walsh & Pink, 2021), and how this idea compares to our traditional ideas of student safety. Work by the Australian Federal government on cyber safety will be visited to understand how we might enhance this concept with a more holistic mindset.

Finally, student self-control will be touched on (Cowling, 2015). Students of the 21st century face a venerable plethora of possible resources that they can access, with little in the way of age restrictions, or clear indicators of their quality. We will discuss fake news and information overload, understanding how these concepts might fit into the broader narrative.

Through interrogating each of these ‘four S’s’: Skills; Screen Time; Safety; and Self-Control, we will propose a new way to look at the digital native that will set a trend going forward, moving us from digital natives to a clearer, more specific model that suits the iKids emerging out of the post-COVID world.
Algunas reflexiones sobre el derecho a la belleza en las ciudades
Authors: Casales García Roberto
Published: February 2022

La presente nota crítica pretende ahondar sobre las implicaciones que tendría defender un derecho a la belleza en las ciudades, tomando como punto de partida tanto la noción heideggeriana de ‘habitar’, como la caracterización Whyte de ‘derecho’. La tesis de fondo es que la belleza contribuye a hacer de cada ciudad un lugar habitable, lo cual implica ciertas obligaciones tanto para aquellos que las gobiernan, como para aquellos que las habitan.
False Beliefs With a Purpose and Optimistic Bias
Authors: Reyes Cárdenas Paniel
Published: February 2022

In their insightful work on False beliefs and their relationship to optimistic bias, Anneli Jefferson and Lisa Bortolotti (2007, 2018) and other members of their research team have been interested in introducing trans-disciplinary understandings of the epistemology behind the social use and the psychological mechanism of optimistic bias and thereby show their useful functions. In this critical note I will reflect on the epistemic value of such phenomena by establishing a dialogue with some of William James' ideas about the place of optimism and the possibility of reading it not so much as a bias but even, in some cases, as an epistemic virtue.
Wpływ wybranych elementów agrotechniki na zawartość olejku eterycznego w korzeniach i kłączach kozłka lekarskiego (Valeriana officinalis L.)

W trzyletnim doświadczeniu polowym przeprowadzonym na glinie lekkiej pylastej badano wpływ rozstawy rzędów oraz sposobu uprawy (płaska i na redlinach) na zawartość olejku eterycznego w surowcu kozłka lekarskiego (Valeriana officinalis L.). Wyniki badań wykazały istotny wpływ sposobu uprawy na zawartość olejku w korzeniach i kłączach. Większą zawartość tej biologicznie czynnej substancji stwierdzono w surowcu roślin z poletek, na których stosowano uprawę płaską. Porównując zawartość olejku w podziemnych organach Valeriana officinalis L. stwierdzono, że korzenie gromadzą więcej tej substancji niż kłącza
Wpływ sposobów regulacji zachwaszczenia na plon i wybrane parametry jakościowe ziarna pszenicy twardej (Triticum durum Desf.) i zwyczajnej (Triticum aestivum L.)

W latach 2003–2005 badano plonowanie i jakość ziarna dwóch linii pszenicy twardej (długosłomej i ościstej LGR 1359/8 i bezostnej o krótkiej słomie LGR 899/17A) w porównaniu z odmianą Helia pszenicy zwyczajnej, w zależności od sposobu regulacji zachwaszczenia. Doświadczenie założono metodą split-plot w trzech powtórzeniach, na glebie brunatnej wytworzonej z lessu w Zakładzie Doświadczalnym w Czesławicach (Płaskowyż Nałęczowski). W doświadczeniu porównywano sześć sposobów regulacji zachwaszczenia, tj. mechaniczny, mechaniczno-chemiczny i mechaniczny, z zastosowaniem pełnej i obniżonej dawki herbicydu Chwastox Trio 540 SL (300 g·l-1 mekoprop + 200 g·l-1 MCPA + 40 g·l-1 dicamba), w terminie optymalnym i opóźnionym, z obiektem kontrolnym nieodchwaszczanym. Plon ziarna pszenicy twardej był przeciętnie w wieloleciu o 28,7% niższy w porównaniu z plonem pszenicy zwyczajnej. Zawartość białka ogólnego i ilość glutenu mokrego w ziarnie pszenicy twardej były zadowalające jedynie w roku 2003 o korzystnym przebiegu pogody. Lepszą jakością charakteryzował się jednak gluten pszenicy zwyczajnej. Herbicyd zastosowany w obniżonej dawce, podobnie jak w dawce zalecanej, nie pogorszył badanych cech. Natomiast bronowanie połączone z herbicydem, jak i sam zabieg bronowania, oddziaływały gorzej na plon ziarna w porównaniu z metodą chemiczną.

En el marco de un macroproyecto sobre desarrollo personal se indaga sobre las opiniones de los jóvenes cartageneros en cuanto al planteamiento y ejecución del proyecto de vida. Además, se busca conocer cuáles son las necesidades y limitantes que estos presentan frente al tema. En la investigación inicial participaron 150 jóvenes con edades comprendidas mayormente entre los 20 y 25 años de estratos 1, 2, 3, 4, 5 y 6. La metodología utilizada es de tipo descriptivo transversal. Los resultados evidenciaron que, una cantidad considerable de los jóvenes no tienen su proyecto de vida estructurado, aun así, manifiestan que les gustaría contar con una guía para la planificación de este. De igual forma, consideran que el éxito está asociado a ciertos atributos personales y que la habilidad que más les gustaría potencializar es la inteligencia emocional. Entre las conclusiones, se resalta la importancia del diseño del proyecto de vida, dado que, permite establecer un propósito que le dé sentido a su existencia. Asimismo, en el camino por el cumplimiento de este se protegen de caer en situaciones riesgosas propias de la etapa de la juventud.
Transdisciplinariedad y Ecosofía: saberes necesarios para comprender y habitar la Tierra
Authors: Hermoso López Araiza Jéssica Paola
Published: February 2022

La forma de acercarse al conocimiento varía a través de las épocas. Tras centenares de años pautados por el paradigma cartesiano, que fragmenta al mundo para comprenderlo, resulta indispensable el tránsito hacia un modo de conocer que dé respuesta a los complejos problemas socioambientales actuales. La transdisciplinariedad aparece entonces como un enfoque que genera vínculos entre las partes escindidas y posibilita sinergias para un mejor entendimiento de la realidad. La Ecosofía, como filosofía ecológica que invita a la humanidad a aprender a vivir armónicamente en el planeta, requiere de una visión transdisciplinaria para comprender las complejas interrelaciones que se dan en el lugar donde vivimos, y la influencia de la sociedad en ellas. Sin un conocimiento amplio e integrado de nuestra Tierra, será difícil elegir la manera óptima de actuar para construir una relación armónica entre el ser humano y su entorno.

El uso de luz UVC combinada con TiO2 puede ser una medida efectiva para combatir la propagación del COVID-19 y reducir la posibilidad de contagio en lugares públicos, hospitales, centros educativos, mediante la desinfección de superficies y medios de transporte donde la salud humana está en riesgo. De este modo, el recubrimiento de TiO2 al ser un compuesto químicamente estable, difícil de deteriorarse, con potencial oxidante capaz de destruir la membrana celular de las bacterias, provocando fugas del citoplasma, es capaz de coagular la proteína de virus e inhibir su actividad, por lo que puede ser un método muy prometedor para la desinfección del virus SARS-CoV-2.
Esta propuesta busca la manera de combatir el esparcimiento del virus COVID-19, por lo que se ha optado por la fabricación de una serie de dispositivos para llevar a cabo una desinfección de superficies con la ayuda de luz UVC+TiO2.
