Published: April 2023

Abstract: Student improvement aims in identifying student behavior traits and patterns using multiple psychometric tests followed by suggesting ways to improve areas of the subject’s interest along with overall psychological balance by continuous testing at constant intervals of time and suggesting the same. To identify the subject’s strengths, weaknesses, and behavioral interests, assessments are carried out on the principle of psychological assessments which aims to assess the students by making them imagine their reactions in various psychological situations. Each response to the question is evaluated with pre-decided scores. Psychometric tests are aimed at measuring a person’s traits, behavior, guidance, and placements/employment to match the person’s capabilities and features like cognitive ability, EQ, IQ, and the tendency to react to predefined situations. Psychometric tests have a huge role to play in the fields of career guidance and employability. These tests suggest your strengths, weaknesses, and imaginative abilities and hint if they suit the particular role. This paper provides a survey on different machine learning algorithms used over the years to recognize personality traits and learning styles which would further contribute to students’ overall improvement.

Published: April 2023

Abstract: Machine learning plays a crucial role in predicting and clas- sifying faults in electrical power systems. The complexity and dynamic nature of these systems make them vulnerable to disturbances and elec- trical faults. Detecting faults in the circuit can aid in maintaining the system by preventing potential damage from occurring. It is particularly important to be able to locate faults in transmission lines to minimize power and revenue losses. In this study, MATLAB software will be uti- lized to simulate and locate faults in transmission lines. A transmission line model will be designed, and a fault toolbox will be employed to create various faults. These faults will be saved and used to train machine learning models to identify the best algorithm with high precision and accuracy.

Published: April 2023

Using functional magnetic resonance imaging (fMRI) technology, we conducted an experiment to explore the effects of gain and loss contexts on cooperation and its brain activation patterns in the Prisoner's Dilemma game. The results showed that even in a loss context, participants still
chose cooperation in nearly half of the experiment trials, but the cooperation rate was higher in a gain context. The results of fMRI showed that the right ventromedial prefrontal cortex, right dorsomedial prefrontal cortex, right temporoparietal junction, and right precuneus were activated
more in the decision process of making a cooperative rather than a defection choice, and also that the activation of the bilateral precuneus and bilateral inferior parietal lobule induced by a cooperative choice was greater in a loss context than in a gain context. Thus, compared with when
they were making a defection decision, in the process of making a cooperative decision, participants might reason and process more on the psychological activities of others, especially in a loss context.

O-GlcNAcylation in Viral Infections: The Sweet and Sour
Authors: Joshua Banda
Published: April 2023

The process of antiviral response is a complex and vast process
involving the interplay of multiple signaling pathways, leading to the
production of cytokines that coordinate the immune response. Recently,
O-GlcNAcylation has been found to play a role in antiviral responses,
especially against RNA viruses. Increased glucose uptake or the
regulation of key proteins in its pathway following infection happen to
induce O-GlcNAcylation. In humoral immunity, O-GlcNAcylation is
responsible for the maturity and migration of immune cells to infected
sites. Interestingly, these functions are context-dependent and may pose
“friend” and/or “foe” effects to the virus as well as the cell/body.
In this study, I examine existing knowledge of O-GlcNAcylation and its
signaling in relation to glucose metabolism and the coordination of
antiviral innate and adaptive immunity for and against viral infection.
Assessment of Ammonium Fluoride as a Mobile Phase Additive for Sensitivity Gains in Electrospray Ionization
Authors: McFadden Jeremy , Ames David
Published: April 2023

Rationale Ammonium fluoride has been shown to improve sensitivity in
electrospray ionization in mass spectral detection when used as a mobile
phase additive. Internal investigation showed sensitivity improvement
for steroid compounds with LCMS. Our work presented here investigates
ammonium fluoride as a mobile phase additive in improving mass spectral
ionization compared with other mobile phases under fully optimized
instrument conditions. Methods For our research, we investigated
ammonium fluoride in comparison with formic acid and ammonium hydroxide
as mobile phase additives to measure sensitivity effects in electrospray
ionization sensitivity. Full source optimization was performed for nine
commercially available compounds at three different organic
concentrations (30, 60, or 90%) with formic acid, ammonium fluoride,
and ammonium hydroxide adjusted mobile phase sets. Optimization results
were compiled to generate individual methods by compound, polarity,
mobile phase additive, and organic concentration, respectively. These
methods were used for final flow injection analysis to objectively
compare compounds analyzed with the different solvent systems under
optimal conditions for each mobile phase composition. Results Negative
ESI data showed 2 – 22-fold sensitivity improvements for all seven
compounds with ammonium fluoride. Positive ESI data showed
> 1 - 11-fold improvement in sensitivity for four of seven
compounds and equivalent (or slight drop in) sensitivity for three of
seven compounds with ammonium fluoride adjustment. Acetaminophen showed
the greatest sensitivity improvement in both polarities, with 7-22-fold
(ESI-) and 4-11-fold (ESI+) improvements in sensitivity, respectively
Conclusions With fully optimized source conditions there is good
likelihood of improving MS sensitivity (ESI-) in using ammonium fluoride
adjusted mobile phase. Investigation with ESI+ analyses showed mixed
results, with four of seven compounds showing improvement and others
showing equivalency or slight loss in sensitivity. Our investigation
focused solely on sensitivity gains achievable in ESI-MS by source
optimization and mobile phase additive selection by flow injection
without chromatography.
ChatGPT in pharmacometrics? Potential opportunities and limitations
Authors: Denejour Denshell
Published: April 2023

The potential of using chatGPT in pharmacometrics was explored in this
study, with a focus on developing a pharmacokinetic (PK) model for
standard half-life factor VIII. Our results demonstrated that chatGPT
can be utilized to accurately obtain typical PK parameters from
literature, generate a population PK model in R, and develop an
interactive Shiny application to visualize the results. ChatGPT’s
language generation capabilities enabled the development of R codes with
minimal programming knowledge and helped identify and fix errors in the
code. While chatGPT presents several advantages, such as its ability to
streamline the development process, its use in pharmacometrics also has
limitations and challenges, including the accuracy and reliability of
AI-generated data, the lack of transparency and interpretability of AI.
Overall, our study demonstrates the potential of using chatGPT in
pharmacometrics, but researchers must carefully evaluate its use for
their specific needs.

Performance and Meat Quality Of Males Chicken Of 2 Lines Sasso (S51 And S31) Reared by Free Range System
Authors: Hoan Nguyen Duy
Published: April 2023

In hatcheries, the majority of males are killed shortly after hatching as they are considered waste, which is wasteful. Meanwhile, the interest of consumers in products from alternative systems (organic, free-range) is increasing. Stemming from the above fact, we had a idea that is to use one-day-old males, which continue to be raised freely to produce good quality chicken. This study was carried out at Hai Yen farm, Thai Nguyen province on 2 broiler Saso chicken lines: low-weight line (SA51) and heavy-weight lines (SA31), 150 male one-day-old chicks each line (5 repeats) reared in captivity to 21 days with density 6 birds/ m2, then free range reared in the garden with natural grass and fruit tree with density 5m2/ bird, monitor up to 90 days of age. The aim of this study was to evaluate the performance and compare the meat quality of two broiler lines at 49 and 90 days of age. The result as followed: Live weight, carcass yield, breast meat yield and the proportion of abdominal fat were significantly higher (P < 0.001) in SA31 at both ages. The proportions of fat in the breast meat were significantly lower (P < 0.01) in SA51 at both ages. The value of pH 24 h was significantly higher in SA51 and the meat was darker (P < 0.001) in these chickens. The overall acceptability was significantly better (P < 0 01) in SA51 at 90 days of age. The males are acceptable for an alternative system of poultry meat production from the aspect of meat quality.
The Problem of Antibiotic Resistance Control: A Possible Alternative to Antimicrobials in Veterinary Medicine
Authors: Ushkalov Valerii
Published: April 2023

Aim of Study: The study included prospects for using autogenous immunobiological drugs as an alternative to antimicrobials. Materials and Methods: For the analysis databases of WHO–World Health Organization, WOHA–World Organization for Animal Health, FAO–Food and Agricultural Organization, CDC–Center for Control and of disease prevention in the USA, ECDC– European Center for Disease Control and Prevention, EFSA–European Food Safety Authority, as well as informational Internet resources of scientific journals, normative legal acts of Ukraine. The Results: According to the results of the conducted analysis, the global spread of microorganisms resistant to the action of antimicrobial drugs was established, which jeopardizes the possibility of effective treatment of infectious diseases. In Ukraine, as in other developed countries of the world, strict regulation of the circulation of antimicrobials has been adopted at the legislative level, which inevitably leads to the limitation of their use. International experience shows that restrictions on the use of antimicrobial agents should be compensated by measures aimed at increasing the level of biosafety. The use of autogenous immunobiological drugs for the specific prevention of infectious diseases of bacterial etiology can be a reasonable alternative to antibiotics in veterinary medicine. Conclusions: The introduction of new rules for the circulation of veterinary antimicrobial drugs will significantly affect the level of use of antimicrobial drugs. A reasonable alternative to antimicrobial agents is the use of autogenous immunobiological agents.

Certification exams conducted online must be of the same quality as those conducted on-site. To achieve this, it is necessary to conduct a study in which assessors need to identify obstacles in implementing online certification examinations which have been implemented during the Covid-19 pandemic. The study aims to analyze the perspective of the assessors to identify the barrier factors, understand the interrelation among them, and propose improvements to the online application process. The method applied was the MICMAC (Matrix of Cross-impact Multiplications Applied to Classification), a structural model, to analyze the variables based on their influence and dependence driving force. A case study was conducted on the Indonesia Hydraulic Engineer Association. The data was collected from a focus-group discussion with the assessors. The result revealed that the barrier factors consist of technical aspects, such as internet connection delay, hackers and viruses, and unverified e-document; and social aspects, such as questioning skills limitation, non-verbal communication skills limitation, and environment distraction. The study found that internet connection delay and questioning skill limitations are the barriers with the highest influence beyond other barriers in the online assessment process. Also, the questioning skills limitation factor has the highest dependency on other barriers. Hence, it can be proposed that the curricula of the assessors’ training and/or certification program, should be incorporated with the questioning skill in an online assessment environment.

Authors: Dąbrowska Karolina , Zaczek Zuzanna , Majewska Krystyna , Sobocki Jacek
Published: April 2023

Total parenteral nutrition (TPN) is a life-saving nutritional therapy in conditions where enteral nutrition is contraindicated or inadequate. However, it has been associated with side effects, one of which is parenteral nutrition–associated liver damage (PNALD). The main features of PNALD are cholestasis, fatty liver disease, and early fibrosis, followed by disease progression, cirrhosis, and liver failure. Risk factors for parenterally fed patients include short bowel syndrome, bacterial overgrowth and translocation, disturbances in hepatobiliary circulation and lack of enteral nutrition, and the choice of an inappropriate fat mixture. The source of the oil present in lipid emulsions is believed to play an important role in the development of long-term complications.

This review analyzes the current literature and research on the pathogenesis of PNALD. Likewise, possible options for preventing this complication were discussed.

Published: April 2023

In view of the shortcomings of traditional wall defect detection methods, such as small detection range, poor accuracy, non-portable device, and so on, a wall defects detection device based on Compton backscattering technology is designed by Monte Carlo method, which is mainly used to detect the size and location information of defects in concrete walls. It mainly consists of two parts, the source container and the detection system: first, through the simulation and analysis of the parameters such as the receiving angle of the backscattered particles and the rear collimating material of the detector, the influence of the fluorescent X-ray peak of the detector collimating material on the backscattered particle counts is eliminated and the detected error is reduced; second, the ring array detector design, compared with single array detector and surface array detector, can facilitate real-time detection of defect orientation, expanding the single scan range and improving the detection efficiency. After simulation and comparative analysis, the relevant optimal parameters are obtained: the object is detected using a Cs-137 γ-ray source with an activity of 6 mCi, and a ring detector consisting of four 0.5-inch cube-shaped CsI scintillator detectors is placed at 150° to receive the backscattered photons. The simulation analysis using the Monte Carlo FLUKA program showed that the maximum depth of wall defect detection is 8 cm, the maximum error fluctuation range of defect depth and thickness is ±1 cm, the overall device weight is <20 kg, and the measurement time is <5 min.

BACKGROUND. Otosclerosis is a primary disease of the human otic capsule and stapes stage, being a frequent cause of conductive hearing loss in our country. The surgical treatment of choice is stapes surgery and prosthesis placement, performed in a conventional way, with a surgical microscope, for 30 years in our hospital. Recently, the option of performing stapes surgery endoscopically was introduced in our centre.

OBJECTIVE. To evaluate the results in stapes surgery for otosclerosis between the conventional microscopic versus endoscopic procedure.

MATERIAL AND METHODS. An observational, analytical and retrospective study on patients undergoing stapes surgery with microscopic and endoscopic technique was conducted. Data such as age, sex, state of origin, affected ear, as well as the technique used, duration of surgical intervention, hearing gain and postsurgical complications were taken. Data were taken from the records of patients admitted to the hospital. Descriptive statistics, Mann-Whitney U and Pearson’s Ji2, were used, considering a value of p≤ 0.05 as significant.

RESULTS. No significant differences were found in surgical time or postoperative hearing between the two surgical techniques. The female sex was the most intervened. There was no significant difference between the post-surgical complications of both groups.

CONCLUSION. Both procedures appear to be effective, with similar risks and postoperative results for the surgical treatment of otosclerosis.

Stocks are an investment instrument that is starting to be in great demand by the public today. However, stock prices are fluctuating, making people feel doubts about when they are going to invest. To overcome these doubts, we need a way to predict stock prices. This study aims to predict stock price fluctuations using Facebook's Prophet Algorithm to help people decide their investment in stock. The research object used is BBCA and TLKM stock price data in the form of a time series from 03 May 2021 to 28 April 2022 with stock price testing data for the next week, namely 01 May 2022 to 07 May 2022. From the training and testing process done, a prediction is produced that is very close to the original value. Using the RMSE, MSE and MAE measurements, we get RMSE 49.6, MSE 2462.1 and MAE 37.5 for BBCA and RMSE stocks, namely 21.3, MSE 456.5 and MAE 19.2 for TLKM shares. The conclusion is that Facebook's Prophet Algorithm is suitable for predicting stock prices.

La presente investigación se ejecutó en la parte alta de la microcuenca del Río Azul, distrito Hermilio Valdizán, provincia Leoncio Prado, departamento de Huánuco, con la finalidad de comparar el Uso Actual frente a la Capacidad de Uso Mayor de tierras, para determinar los conflictos que en ella se encuentran en base al Reglamento de Capacidad de Uso Mayor (D.S. N° 017-2009-AG). Se emplearon curvas de nivel de una hoja restituida con una separación de 30 m. Los resultados se complementaron con visitas a campo y los datos del análisis de suelo, apoyados con el programa ArcGis 10.1. Se delimitó la parte alta de la microcuenca, con un área de 6037,66 ha y se elaboraron los mapas de pendiente, fisiográfico, capacidad de uso mayor, uso actual de tierras, y de conflictos de uso. Se encontraron los siguientes grupos de Capacidad de Uso Mayor: 3735,09 ha de tierras aptas para cultivos permanentes, 1466,13 ha de tierras de protección, y 758,05 ha de tierras aptas para producción forestal. El uso actual presentó 2214,05 ha de tierras con cultivos permanentes (café, plátano, café- plátano y té), 1826,46 ha de tierras con bosque secundario y purmas, y 1631,87 ha de tierras con bosque primario.

Evalúa el efecto de la escarificación ácida y estratificación en frío para la germinación de semillas de palmera pona (Ceroxylon peruvianum Galeano, Sanin & Mejía), se recolectaron frutos provenientes de la localidad de San Carlos, Región Amazonas. El fruto tuvo un peso promedio de 3,71g y diámetro de 1,85 cm; las semillas tuvieron un diámetro de 1,2 cm, humedad de 29,6% y el peso de 1000 semillas fue de 1120 g. Las semillas se secaron a temperatura ambiente. Para la escarificación de las semillas se empleó H 2 SO 4 concentrado (98%) por 10 y 15 minutos. La estratificación en frío se realizó en arena de río húmeda a 3°C en periodos de 14 y 21 días. Las semillas tratadas fueron colocadas en bandejas de plástico, empleando como sustrato musgo y una temperatura de germinación de 24°C. Se evaluó el porcentaje de semillas que presentaron la emisión del botón. Cuando se empleó H 2 SO 4 por un periodo de 15 minutos, se obtuvo 13,8% de germinación, que se caracterizó por ser del tipo adyacente. Con la estratificación en frío sólo se obtuvo 8,8% de germinación.

En esta investigación, se evaluó el efecto de la luz ultravioleta (UV-C) sobre el crecimiento microbiano y la calidad sensorial en hojas de rúcula, inoculadas con Escherichia coli (E. coli). Las hojas se lavaron con NaOCl (100 mg-L"1, pH 6,5) y se inocularon con E. coli (6,2 log UFC • g"1). Posteriormente, estas fueron tratadas con radiación UV-C de 5 a 25 kJ-m"2yun testigo sin aplicación. Se envasaron en bolsas perforadas (aire) y almacenadas a 5 °C durante 10 días. La radiación UV-C disminuyó el recuento inicial de enterobacterias y E. coli (entre 0,1 y 0,8 unidades log, respectivamente) con respecto al testigo. Las altas dosis, iguales o superiores a 20 kJ-m"2, afectaron negativamente la apariencia general e intensidad de color de las hojas. Las dosis entre 5 y 15 kJ-m"2 presentaron una mayor reducción en el crecimiento de E. coli y enterobacterias; así como también, una mejor apariencia e intensidad de color en hojas de rúcula.
