Stock Market Prediction and Visualisation
Authors: Singh Arpita , Mazhari Basar Imam , Gupta Karan
Published: April 2024

Abstract: Stock price forecasting is a widely discussed and significant topic in both financial and academic circles. The stock market is inherently unpredictable, lacking clear rules for estimating or predicting share prices. Various methods, including technical analysis, fundamental analysis, time series analysis, and statistical analysis, have been employed to forecast stock prices. However, none of these methods consistently serve as reliable prediction tools. In this paper, we explore the implementation, prediction, and analysis of stock market prices. Artificial Neural Networks and Machine Learning prove effective for forecasting stock prices, returns, and modeling stock behavior. By conducting statistical analyses, we establish relationships between selected factors and share prices, contributing to more accurate predictions. While the stock market remains inherently uncertain, this paper aims to apply data analysis and prediction concepts to forecast stock prices. In the era of global digitization, stock market prediction has undergone significant technological advancements, transforming traditional trading models. As market capitalization continues to rise, stock trading becomes a focal point for financial investors. Analysts and researchers have developed tools and techniques to predict stock price movements, aiding decision-making. Advanced models leverage non-traditional textual data from social platforms for market prediction. Machine learning approaches, including text data analytics and ensemble methods, have significantly improved prediction accuracy. However, analyzing and predicting stock markets remains challenging due to dynamic, erratic, and chaotic data. This study explores machine learning-based approaches for stock market prediction, emphasizing a generic framework. By critically analyzing findings from the last decade (2011–2021) from digital libraries like ACM and Scopus, we provide insights for emerging researchers to delve into this promising area.

Published: April 2024

Abstract: The escalating motorcycle accident rates highlight the pressing need for improved safety measures. Helmets, a crucial safety gear, are often neglected, contributing significantly to fatalities. This paper addresses the pervasive issue of noncompliance with motorcycle safety rules, focusing on helmet usage and triple riding. Existing systems for monitoring lack precision, prompting our proposed Bike Traffic Violation System. Leveraging Haar Cascade and YOLOv3 models, it identifies motorcycles, detects riders without helmets, instances of triple riding, and even empty parking spots with unprecedented accuracy. The Machine Learning component employs a Support Vector Classification model, bolstered by 4-fold cross-validation, ensuring robustness. This innovative system provides real-time insights into traffic violations, enabling prompt interventions by law enforcement agencies. It overcomes manual identification shortcomings, offering a comprehensive solution for enforcement and awareness campaigns. In summary, our Bike Traffic Violation System not only advances automated traffic rule monitoring but introduces a novel methodology for precise detection, significantly contributing to enhanced road safety and accident prevention.

Mudanças nos padrões de segregação das cidades médias de São Paulo entre 2000 e 2010
Authors: Araujo Agnes Silva , Barros Joana , Saraiva Marcus Vinícius Pereira
Published: April 2024

O Brasil passou por mudanças políticas e econômicas que levaram à redução das desigualdades sociais no período entre 2000 e 2010. Estudos apontam que nesse mesmo período o nível de segregação residencial nos espaços metropolitanos aumentou, ao contrário de uma redução acompanhando as desigualdades. Este artigo vem contribuir com essa frente de estudos, analisando a segregação residencial em cidades médias, quantitativamente e espacialmente, no período entre 2000 e 2010, com o objetivo de quantificar o grau de segregação em cinco cidades médias paulistas e analisar a evolução de seus padrões espaciais, por meio de uma perspectiva comparativa. A mensuração da segregação, utilizando índices espaciais globais e locais para as cidades selecionadas, indicou uma tendência de aumento da segregação residencial similar aos identificados por estudos para áreas metropolitanas, no qual os grupos socioeconômicos de altíssima e baixíssima renda se destacam como os mais segregados, mas não para todas as cidades. Também foram identificados grau e padrão de segregação inalterados no mesmo período. Esses resultados são discutidos no contexto das transformações urbanas ocorridas nas cidades médias, incluindo a valorização imobiliária de determinados setores das cidades, enquanto os processos de periferização da população de baixa renda se mantiveram.
PERTANGGUNGAN RESIKO MENURUT FATWA DSN-MUI NO. 39 TAHUN 2002 TENTANG ASURANSI HAJI: STUDI PADA KEMENAG KOTA BANDA ACEH

Published: April 2024

This article aims to analyse the practice of Hajj insurance at the Ministry of Religious Affairs of Banda Aceh City with a review according to Fatwa DSN-MUI Number 39 of 2002 concerning Hajj insurance. The role of the government in the management of Hajj insurance and the mechanism for submitting Hajj insurance claims are analysed. The problems in this study focus on how is the practice of Hajj insurance for pilgrims and the mechanism for submitting Hajj insurance claims at the Ministry of Religious Affairs of Banda Aceh City with relevance to the DSN-MUI Fatwa Number 39 of 2002 concerning Hajj Insurance Practices. The primary data is gathered from interviews and observations. While secondary data is obtained from the results of research related to this study. The results showed that, first, the insurance practice at the Ministry of Religious Affairs of Banda Aceh City is only limited as a facility provider who proposes to the Central Ministry of Religion Office as a policy holder, so that the insurance claim process occurs at the central level and can be confusing for pilgrims. Nevertheless, the Hajj insurance used by pilgrims is considered in accordance with Islamic teachings because it is sharia-based. Second, the mechanism for submitting insurance claims, families can apply for insurance to the provincial ministry of religion office which will then be submitted to the centre while carrying a number of requirements. Some of the requirements include a death certificate (SKK), a statement letter of heirs from the sub-district and the account number of the deceased or heirs. Third, in the review of the DSN-MUI fatwa No.39 of 2002 concerning Hajj insurance, the practice of Hajj insurance that occurs at the Ministry of Religious Affairs of Banda Aceh City is still less than optimal. Hajj pilgrims do not even know at all about the insurance claim process. Especially for pilgrims from the regions, the process of submitting claims is considered difficult to understand. In fact, the heirs of pilgrims often do not know how to submit insurance claims used by pilgrims, the absence of representatives from PT Asuransi Takaful Keluarga in the regions is also an obstacle in the process of submitting claims, so that the families of pilgrims face challenges in submitting claims with a long procedures.

Authors: Herrero - Villarreal Diana , Calderón Badilla Yency
Published: April 2024

RESUMEN: Esta ponencia es acerca de las video tutorías en física y la importancia que tiene establecer una metodología que contribuya en el aprendizaje de esta disciplina. Esto implica que el equipo docente comprenda no sólo cómo aprende física la persona estudiante, sino también cuál o cuáles estrategias de aprendizaje requiere el estudiantado para las sesiones sincrónicas de video tutoría. Para sistematizar esta experiencia se aplicó un cuestionario a 51 estudiantes para conocer su percepción acerca de a) la metodología que estaban utilizando sus docentes de física, b) las razones para no participar de manera sincrónica y c) los motivos que consideran más probables para no participar hablando o utilizando el chat durante las video tutorías. A partir del cuestionario aplicado y las recomendaciones de un tutor destacado por las devoluciones del estudiantado, se diseñó una propuesta de metodología para implementar las video tutorías en las asignaturas de física (teoría). Esta propuesta fue validada con el equipo docente de la Cátedra de Física mediante un grupo focal. Dentro de los principales resultados se destaca la necesidad de planificar cada una de las video tutorías que se implementen en las asignaturas de física, la importancia del ambiente de aprendizaje, el uso apropiado del tiempo durante el desarrollo de las video tutorías, así como el abordaje de problemas de dificultad creciente.

Authors: Méndez Coto Moisés , Rodríguez Soriano Iván Manuel
Published: April 2024

Este artículo tiene como objetivo presentar la relación de las tendencias en TICs aplicadas al campo de las ciencias de la salud con la nueva carrera de Sistemas de Información en Salud, a partir de la actualización del perfil profesional y el diseño del nuevo plan de estudios que integra habilidades y destrezas claves para la formación de los profesionales. Como parte de la metodología, se parte de un estudio exploratorio realizado a una muestra probabilística de estudiante activos y egresados de la carrera de Registros y Estadísticas en Salud (REDES) a quienes se aplicó un cuestionario digital entre 2021 y 2022. A partir de las respuestas de los cuestionarios permitieron construir un perfil demográfico de los estudiantes, características laborales y valoración de las habilidades y destrezas adquiridas para la administración de Sistemas de Información en Salud, entre otros. Se concluye que REDES se caracteriza por tener un estudiantado joven y altamente feminizado, que se localiza principalmente en zonas lejanas al Gran Área Metropolitana (GAM) y que en su mayoría aún están intentando vincularse a algún nicho laboral, aunque el horizonte de empleabilidad continúa estando dominado por la institucionalidad pública y se desconocen las oportunidades existentes en el sector privado, se espera que con la transición a la nueva carrera, disminuya la brecha identificada en el área de las TICs.

Background and Aims. Since the war in Ukraine which began on
February 2022, many pediatric oncology centers have welcomed patients
from Ukraine. To understand the needs of patients and families arriving
at our hospital, an anonymous questionnaire investigated the families’
backgrounds, feelings and impressions about hospitality and care.
Methods Twenty items investigated how patients had reached
Italy, from whom they received help (logistically/economically);
emotions regarding their statusas war refugees; knowledge, expectations,
and opinions about Italy and Italians; the quality of medical care
received and relationships with the healthcare staff; suggestions to
improve assistance. Results Questionnaires were completed by
19/32 patient/parents in the time interval May-November 2022 in two
different pediatric-oncology centers in the north of Italy. Most
families had reached Italy (58%) and received medical care (95%)
thanks to the help of Charities and the Italian Public Health Care
System. Many of them (69%) declared themselves to be satisfied by the
assistance. The Italian population appeared friendly (95%) and generous
(58%). The improvement of their stay correlated with the positive
outcome of their children (15%), the presence of the whole family
(15%), the end of the war (10%), and the overcoming of language
barriers (10%) Conclusions. Taking care of children from a
different country suffering the traumatic experience of fleeing their
country in addition to the equally traumatic condition of cancer
disease, is a huge task. Our questionnaire aimed at obtaining a better
understanding of families’ conditions, not at bridging the relational
gap due to different culture and experiences.
Shining Light on Carbon Dots: A Biocompatible Approach to Potent Antibacterial Activity and Biofilm Disruption
Authors: Zhang Qingsong , Fu Jianxin , Lin Hong , Xuan Guanhua , Zhang Weiwei , Chen Lingxin , Wang Guoqing
Published: April 2024

In spite of tremendous efforts dedicated to addressing bacterial
infections and biofilm formation, the post-antibiotic ear continues to
witness a gap between the established materials and an easily accessible
yet biocompatible antibacterial reagent. Here we show carbon dots (CDs)
synthesized via a single hydrothermal process can afford promising
antibacterial activity that can be further enhanced by exposure to
light. By using citric acid and polyethyleneimine as the precursors, the
photoluminescence CDs can be produced within one-pot, one-step
hydrothermal reaction in only 2 h. The CDs demonstrate robust
antibacterial property against both Gram-positive and Gram-negative
bacteria and, notably, a considerable enhancement of antibacterial
effect can be observed upon photo-irradiation. Mechanistic insights
reveal that the CDs generate singlet oxygen (1O2) when exposed to light,
leading to an augmented reactive oxygen species level. The approach for
disruption of biofilms and inhibition of biofilm formation by using the
CDs has also been established. Our findings present a potential solution
to combat antibacterial resistance, and offer a path to reduce
dependence on traditional antibiotics.
Active Demand and its Integration into the Distribution System with the Use of Metaheuristic Techniques: Opportunities, Conceptual Evolution, and Application Challenges
Authors: Obando Edgar , Lopez Dahiana , Carvajal Sandra
Published: April 2024

Non-conventional renewable energy sources integration into distribution
systems, data science, and enabling technological infrastructures
present formidable challenges in transforming distribution systems,
particularly in accommodating active demand. With escalating energy
demand emphasizing the need for dependable tracking and predictive
methodologies. These methodologies are essential for managing
Distributed Energy Resources (DERs) and digital infrastructure.
Effectively monitoring active demand requires a comprehensive
understanding of the transactional system concept, encompassing digital
infrastructure, and decentralized demand. Despite the increasing
prominence of metaheuristic techniques in demand response integration,
existing literature predominantly focuses on specific techniques rather
than providing a characterization of dynamic transaction integration for
active demand. Technological advancements, such as smart meters and
communication systems, propel the evolution of the demand concept from
rudimentary consumption measurement to active consumer involvement. This
paper reviews the evolutionary trajectories of essential concepts in the
energy sector, namely active demand, DERs, and transactive systems.
Through in-depth analysis, Simultaneously, the paper systematically
examines prevalent metaheuristic techniques in the literature,
specifically focusing on their role in integrating and predicting the
behaviors of active demand and DERs. The paper presents a methodology
that, if utilized as a roadmap, would facilitate the evidence of stages
required for the integration of DERs .

Objectives: Nearly 80% of children within the U.S. live with a
sibling, and siblings exert a unique and typically lifelong influence on
one another. Past research supports an influence between psychopathology
of one individual and the psychological functioning of their siblings.
Recently this relationship has been examined in the context of
borderline personality disorder (BPD), such that siblings of individuals
with BPD are at heightened risk of developing psychiatric disorders and
engaging in problematic behaviors. Beyond the influence siblings have on
one another, there is growing work demonstrating that many siblings of
individuals with mental health difficulties face unique challenges in
terms of balancing care for themselves and care for their siblings, and
yet don’t have resources available for these specific challenges.
Methods: The current study utilizes written statements from
applications submitted to the Family Connections
program by siblings of those with emotion regulation (ER) difficulties
or BPD. A qualitative analysis is utilized to examine statements written
by these sibling applicants, and salient themes are discussed.
Results/Conclusion: We hope to clarify the experiences of
siblings within these dyads and make a case for increased opportunities
for these siblings to access care and support, in order to improve
outcomes and support for both siblings.

RATIONALE: Glutamate carboxypeptidase II (GCPII) catalyzes the
hydrolysis of N-acetyl-aspartyl-glutamate (NAAG) to yield glutamate
(Glu) and N-acetyl-aspartate (NAA). Inhibition of GCPII has been shown
to remediate the neurotoxicity of excess glutamate in a variety of cell
and animal disease models. A robust high-throughput LC/MS/MS method was
needed to quantify GCPII enzymatic activity in a biochemical
high-throughput screening assay. METHODS: A dual-stream
LC/MS/MS method was developed. Two parallel eluent streams ran identical
HILIC gradient methods on BEH-Amide (2x30mm) columns. Each LC Channel
was run independently, the cycle time was 2 min per channel. Overall
throughput was 1-minute per sample for the dual-channel integrated
system. Multiply injected acquisition files were split during data
review, batch metadata was automatically paired with raw data during the
review process. RESULTS: Two LC sorbents, BEH-Amide and Penta-
HILIC, were tested to separate the NAAG cleavage product Glu from
isobaric interference and ion suppressants in the bioassay matrix. Early
elution of NAAG and NAA on BEH-Amide allowed interfering species to be
diverted to waste. The limit of quantification was 0.1 picomoles for
Glu. The Z-factor of this assay averaged 0.85. Over 36,000 compounds
were screened using this method. CONCLUSIONS: A fast gradient
dual-stream LC/MS/MS method for Glu quantification in GCPII biochemical
screening assay samples was developed and validated. HILIC separation
chemistry offers robust performance and unique selectivity for targeted
positive mode quantification of Glu, NAA and NAAG.
Design of a sustainable out-of-town office building in Morocco: Combining the Multi-Criteria Decision Making (MCDM) approach for material selection to the rooftop PV system design
Authors: Hallaoui Z. El
Published: April 2024

Achieving the building’s sustainability requires the assessment of its
life-cycle, involving the selection of sustainable materials during the
construction stage and adopting rooftop PV system in the exploitation
stage, with the objective to lower its carbon footprint. This paper
reports a case study for the design of a sustainable office building,
located out of town, integrating PV panels for autonomous electricity
production. For this purpose, the multi criteria decision making
analysis was carried out to select the optimum sustainable materials,
and the energetic balance of the building was evaluated. Accordingly,
the required rooftop PV panels and the associated area were then
estimated, while a storage battery was included for the building’s
continuous electrical supply. Using the Weighting Sum Method, and
considering the technical/environmental and financial constraints,
double wall in hollow brick and expanded polystyrene floor were
selected, while expanded polystyrene was used as the insulating
material. The energetic analysis of the building performances indicated
an average annual heating and air cooling requirement of 0.57 kWh/m
and 36.87 kWh/ m , respectively.
Finally, the on-roof PV panels required a nominal peak power of 400kWp
with 1218m area, while a 82kAh storage battery
capacity was evaluated for a continuous electricity production.

Published: April 2024

Background: Although there are several health facilities with
infrastructure to cater to healthcare services, there are still
healthcare facilities with inadequate infrastructure in eThekwini
Municipality, KwaZulu-Natal Province, South Africa to provide
comprehensive healthcare services. This study investigated the
perceptions of healthcare workers and patients about the impact of
health facility infrastructure on the provision of healthcare services
in this province. Objectives: This study aimed to determine the
perception of healthcare workers and patients about the impact of health
facility infrastructure on healthcare services at Goodwins Clinic in
eThekwini Municipality, KwaZulu-Natal, South Africa. Method:
This qualitative study applied phenomenological design by conducting an
individual in-depth interview with patients (n= 20) and healthcare
workers (n= 10) purposively selected in 2022. Data were analysed using
Colaizzi’s phenomenological analysis framework. Results:
Participants reported that health facility infrastructure affects
healthcare services. Furthermore, old facility structures, scattered
structures, and limited working spaces were found to be the leading
factors affecting healthcare services in the facility.
Conclusion: The facility’s structural design factors need to be
considered to ensure that the health facility structure is adequate to
deliver healthcare services and motivate radical transformation to take
place in measuring and managing healthcare facilities.
Contribution: The results will assist in improving health
facility structure and healthcare services, help health facilities
prepare for National Health Insurance and easily reach SDG 3, motivate
future research, and provide information that will assist in
implementing programs to reduce poor healthcare services.
Highlights: Patients and healthcare workers perception was
investigated whereby their views stipulated that health facility
infrastructure affects healthcare services. Poor infrastructure was
noted as well and inappropriate healthcare services.

Published: April 2024

CRISPR/Cas9 technology in conjunction with somatic cell nuclear
transplantation (SCNT) provides the primary approach to producing
gene-edited pigs, and targeting nuclear donors with CRISPR/Cas9 is
crucial. Gene-edited nuclear donors are inefficient due to poor editing
efficiency and low delivery efficiency, which are highly associated with
CRISPR/Cas9 form selection. Nevertheless, there is not a straightforward
method to evaluate CRISPR/Cas9 editing efficiency on the porcine genome.
In this study, a fluorescence report signal and micropattern
arrays-based platform was developed to visually assess the efficiency of
CRISPR/Cas9 editing. Based on the quantity and state of cells grown on
micropattern arrays, 200 μm in diameter and 150 μm in spacing were
optimal specifications for culturing porcine cells. The editing
efficiency of three different CRISPR/Cas9 system forms: DNA, mRNA, and
Ribonucleoprotein (RNP) were rapidly evaluated using this platform, with
mRNA proving the most effective. Subsequently, four homozygotes with
β4GalNT2 gene knockout were quickly obtained by mRNA-based form, which
lays the groundwork for the subsequent generation of gene-edited pigs.
This platform makes gene knockout efficiency evaluation rapid,
intuitive, and efficient. It also holds great promise for customizing
evaluation platforms for different cell types, evaluating delivery
techniques, and swiftly testing innovative gene editing tools.
