A Comparison between the Morphologies and Structures of Dwarf Galaxies with and without Active Massive Black Holes
Authors: Kimbrell Seth J. , Reines Amy E. , Greene Jenny E. , Geha Marla
Published: November 2023

We study the morphologies and structures of 57 dwarf galaxies that are representative of the general population of dwarf galaxies and compare their demographics to a sample of dwarf galaxies hosting optically selected active galactic nuclei (AGNs). The two samples span the same galaxy stellar mass (109 ≲ M
⋆/M
⊙ ≲ 109.5) and color range, and the observations are well-matched in physical resolution. The fractions of irregular galaxies (14%) and early types/ellipticals (∼18%) are nearly identical among the two samples. However, among galaxies with disks (the majority of each sample), the AGN hosts almost always have a detectable (pseudo)bulge, while a large fraction of the non-AGN hosts are pure disk galaxies with no detectable (pseudo)bulge. Central point sources of light consistent with nuclear star clusters are detected in many of the non-AGN hosts. In contrast, central point sources detected in the AGN hosts are, on average, more than 2 orders of magnitude more luminous, suggesting the point sources in these objects are dominated by AGN light. The preference for (pseudo)bulges in dwarf AGN hosts may inform searches for massive black holes in dwarf galaxies and attempts to constrain the black hole occupation fraction, which, in turn, has implications for our understanding of black hole seeding mechanisms.

Galaxy clusters are the most recently formed and most massive, gravitationally bound structures in the Universe. The number of galaxy clusters formed is highly dependent on cosmological parameters, such as the dark matter density, σ
8, and Ω
m
. The number density is a function of the cluster mass, which can be estimated from the density and temperature profiles of the intracluster medium under the assumption of hydrostatic equilibrium. The temperature of the plasma, hence its mass, is calculated from the X-ray spectra. However, effective-area calibration uncertainties in the soft band result in significantly different temperature measurements from various space-based X-ray telescopes. NuSTAR is potentially less susceptible to these issues than Chandra and XMM-Newton, having larger effective area, particularly at higher energies, enabling high-precision temperature measurements. In this work, we present analyses of Chandra, NuSTAR, and XMM-Newton data of A478 to investigate the nature of this calibration discrepancy. We find that NuSTAR temperatures are on average ∼11% lower than those of Chandra, and XMM-Newton temperatures are on average ∼5% lower than those of NuSTAR. This results in a NuSTAR mass at r

Enhancing the efficiency of the MOX fuel cycle for VVER-1200 using burnable absorbers
Authors: Ozoani Joy , Volkov Yuri
Published: November 2023

Margin adoption in a nuclear power plant (NPP) design is a frequent approach to strengthen the design’s robustness and provide an efficient way to handle uncertainties. However, the current trend of increasing fuel enrichment, including the use of MOX fuel to achieve a higher burnup, leads to non-uniformity in the energy release (power peaking factor) at the level of the fuel rod lattice, thereby causing a great effect on the reactor margins. One of the ways to reduce the power peaking factor is the use of burnable absorbers (BAs) which helps to minimize the power peaking factor. This work aims at enhancing the efficiency of the MOX fuel cycle for VVER-1200 reactor by replacing the Gadolinium burnable absorber to Erbia burnable absorber.

Authors: Ruswanto Ruswanto , Mardianingrum Richa , Septian Ade Dwi , Yanuar Arry
Published: November 2023

The SIRT1 is overexpressed in a number of cancers. As a result, inhibiting SIRT1 may be used as a cancer treatment technique. Modification of 1-benzoyl-3-methylthiourea derivatives was carried out in this study by changing the aromatic side. The designed compounds (94) were subjected to in silico docking, pharmacokinetics, and preclinical testing. In the docking sample, the (4-decyl-N-(methylcarbamothioyl)benzamide (91), 2-(benzyloxy)-N-(methylcarbamo-thioyl)benzamide (93) and N-(methylcarbamothioyl)-2-naphthamide (94) were predicted to display better inhibition of SIRT1, so they were chosen for subsequent molecular dynamic studies. The compound 93 is proposed as a possible anticancer candidate that inhibits SIRT1 based on the screening results from molecular docking, pharmacokinetic predictions, and molecular dynamics.

Published: November 2023

Background:

There is a gap in the availability of continuing education opportunities for labor and delivery nurses regarding trauma-informed perinatal care.

Method:

A continuing education module on trauma-informed pain management in labor was created and distributed to 17 nurses in an intrapartum unit at a hospital in the Midwestern United States. Changes in knowledge, attitudes, skills, and intent to use trauma-informed principles were assessed using a pretest-posttest design and paired
t
test analyses.

Results:

Change in knowledge (
p
= .043) and skills (
p
= .011) was statistically significant. There were no statistically significant changes in attitudes.

Conclusion:

Continuing education opportunities in trauma-informed perinatal care are needed for health care team members who provide care to trauma survivors in labor. Further research on the effectiveness of trauma-informed pain management in labor and birth is necessary to provide additional resources and recommendations for labor and delivery nurses.

A multi-band centroid contrastive reconstruction fusion network for motor imagery electroencephalogram signal decoding
Authors: Xu Jiacan , Li Donglin , Zhou Peng , Li Chunsheng , Wang Zinan , Tong Shenghao
Published: November 2023

Motor imagery (MI) brain-computer interface (BCI) assist users in establishing direct communication between their brain and external devices by decoding the movement intention of human electroencephalogram (EEG) signals. However, cerebral cortical potentials are highly rhythmic and sub-band features, different experimental situations and subjects have different categories of semantic information in specific sample target spaces. Feature fusion can lead to more discriminative features, but simple fusion of features from different embedding spaces leading to the model global loss is not easily convergent and ignores the complementarity of features. Considering the similarity and category contribution of different sub-band features, we propose a multi-band centroid contrastive reconstruction fusion network (MB-CCRF). We obtain multi-band spatio-temporal features by frequency division, preserving the task-related rhythmic features of different EEG signals; use a multi-stream cross-layer connected convolutional network to perform a deep feature representation for each sub-band separately; propose a centroid contrastive reconstruction fusion module, which maps different sub-band and category features into the same shared embedding space by comparing with category prototypes, reconstructing the feature semantic structure to ensure that the global loss of the fused features converges more easily. Finally, we use a learning mechanism to model the similarity between channel features and use it as the weight of fused sub-band features, thus enhancing the more discriminative features, suppressing the useless features. The experimental accuracy is 79.96% in the BCI competition Ⅳ-Ⅱa dataset. Moreover, the classification effect of sub-band features of different subjects is verified by comparison tests, the category propensity of different sub-band features is verified by confusion matrix tests and the distribution in different classes of each sub-band feature and fused feature are showed by visual analysis, revealing the importance of different sub-band features for the EEG-based MI classification task.
A Collaborative Filtering Recommendation Algorithm Model Based on User Feature Transfer
Authors: Han Jing
Published: November 2023

The quality of teaching resources and recommended practices in flipped classrooms determine the advantages and disadvantages of this educational model. However, current teaching resource recommendation platforms suffer from issues such as cold startup and sparse data. In order to address these issues, a collaborative filtering recommendation algorithm based on user feature transfer was proposed and utilized to examine the correlation between students’ preference behavior and the recommendation of teaching resources in flipped classes for tourism management. The aim was to enhance the quality of teaching in current classes. Using this algorithm, a transfer by user feature (TUF) model is constructed. In this model, a soft embedding method is employed to accurately extract user feature information in the auxiliary space. This method addresses the challenge of filling large-scale missing matrices in the auxiliary space. Additionally, singular value decomposition is performed to obtain more precise user features. Finally, an optimized Wiberg algorithm with rapid convergence is designed to solve the constructed model. The performance of this algorithm is measured and compared using two common datasets. Compared to other algorithms, the proposed algorithm demonstrates superior performance and a lower mean absolute error value. In summary, the recommendation algorithm can enhance the quality of resource organization and provide more suitable personalized recommendations for the recommendation platform. This is beneficial for improving the quality of students’ learning.

Authors: Luo Qiyu
Published: November 2023

To improve the practical effect of digital technology (DT) in electronic education platform (ECP) in sports training, this study proposes using OpenPose as the main method of posture matching in sports teaching. MobileNet was introduced to replace the backbone network in OpenPose to improve the efficiency of the model. At the same time, self-attention mechanism (SAM) is introduced to improve the accuracy of the model. In the performance verification results, the proposed algorithm has a mean mean absolute error (MAE) of 0.793 and a root mean square error (RMSE) of 0.628. The accuracy of the proposed algorithm reached a maximum of 0.893 in the test set. The accuracy of the proposed algorithm exceeds 90% in the training set. In the practice of physical education (PE) and training, the absolute error between the actual value and the predicted value does not exceed 1.5 cm, while the relative error does not exceed 1.2%. The minimum absolute error and relative error are 0.01 cm and 0.2%, respectively. The proposed algorithm has high prediction effect and performance, and can be applied to PE training.
New Teaching Model of Professional Big Data Courses in Universities Based on an Outcome-Oriented Educational Concept
Authors: Lv Haiyang , Liu Jingnan
Published: November 2023

Most traditional Big Data courses focus on the cultivation of students’ professional theoretical knowledge but neglect the training of students’ programming skills. To test the effectiveness of students’ programming learning, the study constructed a classification algorithm based on the TCNN model from the perspective of program identification for identifying programs written by students on their own. To improve the convergence speed and to retain more data features of the programs, the study used the Softplus-Relu combined activation function. To avoid overfitting the model, a dropout strategy was also introduced to optimize the existing TCNN model. The experimental results show that the TCNN model with the Softplus-Relu activation function converges faster, and the classification accuracy obtained is higher than 95%. The loss values and classification accuracies obtained with the TCNN-Dropout model are better than those of the GIST-KNN algorithm. The former has a loss value close to 0 and an accuracy rate of 98.9%. Thus, this indicates that the improved TCNN model proposed in the study has advantages in the identification procedure and can be used as a teaching aid for the training of big data professionals.
Intercultural Communication Competence Improvement of Students under the International Education Management Model
Authors: Zhang Jingyao
Published: November 2023

With the acceleration of globalization, international education has gradually become the core content of higher education. In this context, students have encountered lots of intercultural challenges, making the evaluation and improvement of their intercultural communication competence (ICC) a key issue. It is difficult for traditional evaluation methods, such as questionnaire surveys, interviews, and teacher evaluations, to meet the needs of current educational institutions because they are subjective, time-consuming, and inefficient. After describing the ICC evaluation process of students under the international education management model, this study proposed a new automatic evaluation method based on the dual-scale convolutional neural network (CNN) model and the bi-directional long-short-term memory (Bi-LSTM) model of characters and words. The new method evaluated students’ ICC more accurately and objectively, providing a new perspective and tool for future research and educational training.
The Effect of Intelligent Evaluation Technology on Students’ Initiative in Post-lecture Evaluation of Online Teaching
Authors: Wang Zhaona
Published: November 2023

Class evaluation based on intelligent technology is a disruptive innovation and change. Strengthening research, developing key technologies in the education evaluation field, and effectively integrating intelligent technology in higher education evaluation are among the essential measures that can be taken to ensure the high-quality development of higher education. In this study, 352 undergraduates from Anyang Institute of Technology in Henan Province were invited to participate in a questionnaire survey. The influence of four aspects of intelligent evaluation technology (i.e., language analysis, behavioral analysis, emotion analysis, and teaching evaluation techniques) on the initiative of the students in the post-lecture evaluation of online teaching was analyzed. Differences in the initiative of the students in post-lecture evaluation under different frequencies of use of intelligent evaluation technology were measured. Results showed that the overall Cronbach’s α is 0.840 and the Kaiser-Meyer-Olkin value is 0.852, indicating that the questionnaire has very good reliability and validity. Language analysis, emotion analysis, and teaching evaluation techniques have a positive promotion effect on the initiative of the students in the post-lecture evaluation of online teaching. The frequency of use of intelligent evaluation technology after class has a significant influence on the initiative of the students in post-lecture evaluation at the 0.01 level (F = 5.073, p = 0.002). Moreover, the initiative of the students in post-lecture evaluation declines gradually as their frequency of use of intelligent evaluation technology increases. The research conclusions can serve as an important reference for education teaching evaluation mode reform, with artificial intelligence technological support; the interpretability of multidimensional indices (e.g., cognition, emotions, and input) for online teaching quality evaluation; and teaching quality evaluation under man–machine coordination.

Published: November 2023

The study aims to demonstrate the significance of metaverse technology across various disciplines, academic degrees, scientific fields, and academic titles. It also aims to assess the level of knowledge and understanding of university teachers (research sample) regarding metaverse technology. Hence, the descriptive research methodology was based on the method of statistical survey in the sample. It involved a set of organized scientific steps to deduce data from the reality of the statistical sample and its nature in order to achieve the objectives of the study. In this study, a questionnaire was used as a tool to collect data from a random sample of approximately 121 teachers and instructors from the University of Baghdad. This approach helped the study draw important conclusions and make recommendations. Specifically, the study found the following: there is a need for a clear understanding of the importance of implementing metaverse technology in university education; teachers in scientific colleges are more aware of its importance compared to their counterparts in humanitarian colleges; there is a strong call for all universities, colleges, and academic institutions to prioritize the application of metaverse technology in university education; there should be the availability of all necessary supplies and devices; and there should be the creation of an appropriate environment for teachers to effectively use metaverse technology when teaching students.

Published: November 2023

NK cells are a key focus in immuno-oncology, based on their ability to eliminate malignant cells without prior sensitization. Dogs are valuable models for translational immunotherapy studies, especially for NK cells, where critical species differences exist between mice and humans. Given that the mechanism for recognition of “self” by canine NK cells is currently unknown, we sought to evaluate expression of Ly49 in canine NK cells using in silico and high-throughput techniques. We interrogated the identified polymorphism/mutation in canine Ly49 and assessed the potential impact on structure using computational modeling of three-dimensional protein structure and protein-protein docking of canine Ly49 with MHC class I (MHC-I). Bulk and single-cell RNA-sequencing analysis was performed to detect gene expression of Ly49/KLRA1 in resting and activated NK cells. Tertiary protein structure demonstrated significant structural similarity to the known murine system. Molecular docking of canine Ly49 with MHC-I was favorable, converging at a single low-energy conformation. RNA sequencing revealed expression of Ly49/KLRA1 in both resting and activated NK cells and demonstrated almost exclusive expression of the gene in the NK cluster at the single-cell level. Despite prior reports of a mutated, nonfunctional canine Ly49, our data support that the protein product is predicted to bind to MHC-I in a comparable conformation to the murine system and is expressed in canine NK cells with upregulation following activation. Taken together, these data suggest that Ly49 is capable of recognizing MHC-I and therefore regulating NK cell function in dogs.

Effectiveness of prenatal yoga on pregnant women's anxiety and duration of labour
Authors: Indrayani Diyan , Legiati Titi , Sriyanti Chris
Published: November 2023

The birth process involves physical and psychological mechanisms. Anxiety creates physical and psychological tension, interfering with the birth process. The study aimed to analyze the effectiveness of Yoga on pregnant women's an’iety and labor duration. This study used an experimental design with a Randomized Controlled Trial (RCT) involving 60 pregnant women divided into two groups: Yoga and walking (30 participants each). The variables studied were pregnant women's anxiety and the duration of labor. The sampling technique was conducted using block randomization. Data were analyzed using the Independent T-test. The Yoga group attended 30-minute sessions twice weekly, while the walking group engaged in the same frequency and duration of walking until giving birth. Anxiety levels were measured using the Hamilton Anxiety Rating Scale (HARS) before and one month after the intervention in both groups. The duration of labor was measured using partographs and medical records during delivery for both groups. Data were analyzed using the Shapiro-Wilk test and independent t-test. Pregnant women in both the Yoga and walking groups experienced reduced anxiety scores, with a decrease of 11.6%, and statistically significant p-values of <0.05. The duration of labor was significantly shorter in the Yoga group (mean: 2.65 hours, SD: 1.01) compared to the walking group (mean: 4.01 hours, SD: 2.54), with a mean difference of 1.36 hours and a p-value of <0.05. Prenatal Yoga in the third trimester reduces pregnant women's an’iety and shortens the duration of labor. It can be suggested as an alternative exercise for pregnant women to improve maternal health during pregnancy and childbirth.

Published: November 2023

Providing appropriate education to breastfeeding mothers and their families is essential to ensure a high level of breastfeeding implementation. The purpose of this study was to analyze the effect of education and mentoring on increasing knowledge about exclusive breastfeeding. This study employed a quasi-experimental design with two groups, one before and one after testing. The research was conducted in one village during March and April 2023, using purposive sampling techniques. Data were collected through questionnaires. Family empowerment interventions in the form of education and mentoring were administered twice with one-week intervals. Data analysis was performed using an independent t-test with p-value < 0,05. The study revealed significant differences in respondents' knowledge after they received educational interventions and guidance. The results showed a p-value of 0.006, which is less than 0.05, indicating a significant difference in respondents' knowledge before and after the intervention. Education and instruction had a positive impact on respondents' knowledge of exclusive breastfeeding. Both the intervention and control groups showed efficacy. Notably, the intervention group displayed a highly significant increase, as evidenced by the significant difference values. In conclusion, family empowerment through education and assistance has a positive effect on increasing knowledge about exclusive breastfeeding. Enhancing family knowledge, skills, and social support can lead to improved optimal breastfeeding practices, enhanced infant health, and reduced infant mortality.
Impact of Atrial Fibrillation on Heart Failure with Preserved Ejection Fraction: An Observational Cross-sectional Study from Western India
Authors: Shastri Minal Hemant , Vinod Vishakha , Mistry Heti P. , Rathod Vaishnavi Mahendrasinh , Gohil Namra Vinay , Dobariya Riya Kantibhai , Patel Nilay Shetal
Published: November 2023

Background:

Both atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) commonly coexist with overlapping symptoms, risk factors, and shared pathophysiology. Both conditions independently impact left atrial volume index (LAVI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, making it difficult to diagnose HFpEF in AF.

Aim:

The aim is to study the association of AF with NT-proBNP levels, LAVI, and left atrial (LA) size in HFpEF.

Materials and Methods:

An observational study of 40 patients was conducted at a Tertiary Care Center in Western India. Patients above 18 years of age with classical heart failure presentation were included and their clinical history and general and systemic examination were done along with NT-proBNP measurement and two-dimensional echocardiography for assessing heart structure and function.

Results:

Twenty-one patients had sinus rhythm; 19 had AF. AF patients had higher NT-proBNP levels (2599 pg/mL) compared to patients with sinus rhythm (785 pg/mL). AF patients had a greater degree of left ventricular (LV) dysfunction (higher LV end-diastolic dimensions, LV posterior wall thickness, LV mass index, LA diameter, LA volume and LAVI), more prevalence of pulmonary artery hypertension (n = 19 vs. n = 17), higher degrees of diastolic dysfunction (e.g. higher e’ septum, e’ lateral and E/e’), and higher right ventricle systolic pressure as compared to patients with sinus rhythm.

Conclusions:

The present study shows that AF occurs in around half of HFpEF patients, with a higher incidence in women and younger people. Patients with AF have higher rates of right heart failure, severe atrial and ventricular remodeling, and higher levels of NT-proBNP, which indicate an advanced form of the disease.
Improving Self-care Behavior and Removing Barriers by Structured Diabetes Education Program in Primary Health-care Settings of Puducherry: Evidence from a Mixed-method Intervention Study
Authors: Gehlawat Mamta , Subitha L. , Kar Sitanshu Sekhar , Thumati Goutham
Published: November 2023

Context:

Diabetes self-management education (DSME) improves patients’ clinical outcomes and quality of life by encouraging self-care behavior.

Aims:

This study aimed to find out the effectiveness of a DSME by comparing changes in stages of self-care behavior and to explore perceived barriers in diet, exercise, and foot care among patients with type 2 diabetes mellitus in an urban primary health center (PHC) of Puducherry.

Settings and Design:

A mixed-method intervention study was conducted among 314 patients with type 2 diabetes mellitus in two urban PHCs randomly allocated to intervention and control arm.

Subjects and Methods:

The stages of behavior change and barriers perceived in the domains of diet, physical activity, and foot care were captured using a pretested questionnaire. Intervention consisted of DSME along with information leaflets and self-care kits for the intervention group. At the end of 6 months, end-line assessment and in-depth interviews were conducted.

Statistical Analysis Used:

Quantitative data were analyzed in STATA while manual coding and deductive thematic analysis were done for qualitative data.

Results:

Footcare showed an improvement of 31%, while diet and exercise domains saw an improvement of 5% each from preaction to action stage when compared with control arm. The main barriers perceived in dietary modification and foot care were lack of awareness. For exercise, the main barriers were lack of perceived need and being physically unfit. Foot-care barriers witnessed maximum resolution (27%) following the intervention.

Conclusions:

DSME intervention helps in improving stages of behavior change while resolving self-care barriers. Culturally-oriented DSME and patient-tailored interventions are key to empower people living with diabetes by improving self-care.
Some aspects of the craniometry of adult Nigerian indigenous pigs (Sus scrofa) and its application in regional anaesthesia
Authors: Okandeji M.E. , Olaniyi Z.B.
Published: November 2023

Regional anatomy is an important component of surgical and clinical practice because it helps clinicians envisage the  specifics of the structures relevant to the case at hand. This study was designed to evaluate some clinically important  indices which could aid regional anesthesia of the head in the Nigerian indigenous pig (NIP). Twenty-four (10 males and  14 females) skulls of adult NIP were examined to record 10 parameters. Data obtained were statistically analysed using  the Student’s t-test and Pearson Correlation, with significance set at p<0.05. The study revealed that 50% of the indices  were higher in female skulls but were not statistically significant. The mandibular length was, however, significantly  longer in male skulls (19.0 ± 0.41), compared to females (18.0 ± 0.26). The distance from the facial crest to the  infraorbital foramen was 1.3 ± 0.10 cm and 1.5 ± 0.08 cm, while that from the supraorbital foramen to the nasal bone  was 2.1 ± 0.06 cm and 1.9 ± 0.06 cm, in male and female skulls, respectively. Pearson correlation analysis revealed a  positive relationship between the distance from the facial crest to infraorbital foramen and that from infraorbital  foramen to medial canthus of the orbit (r=.669). An accessory supraorbital foramen was seen in 12 (50%) of all the 24  skulls, just as several lateral mental foramina were observed on the rostro-lateral surface of the mandibular rami. Data  generated provide clinically important information on the skull of adult Nigerian indigenous pigs which can be used as  landmarks for tracking and desensitizing the branches of the frontal nerve (supraorbital), the maxillary nerve (Infraorbital) and the mandibular nerve, during the regional anaesthesia of the head, for tooth extraction procedures  and the treatment of injuries and fractures. These results may also be useful for comparative anatomical,  developmental, forensic, and clinical studies.
Molecular characterization of the VP2 protein of BGM-70 adapted low passaged UPM190 infectious bursal disease virus isolate
Authors: Lawal U.N. , Bello M.B.
Published: November 2023

The study evaluated the genetic profile of a low passaged BGM-70 adapted very virulent infectious bursal disease virus  (vvIBDV) isolated in Malaysia in the year 2004 based on the VP2 hypervariable region. Embryonated chicken eggs were  first used to propagate UPM190 12 times before being low passaged in BGM-70 cell line 7 times yielding UMP190BGMP7  whose VP2 nucleotide and amino acid sequences were determined and compared with reference sequences after  Sanger sequencing of the low passage virus. The nucleotide and amino acid sequences of UPM190BGMP7 virus were  similar with the sequences of viruses passaged in chicken embryonated eggs (CEE) but differed with higher BGM-70  passaged viruses. The E270 amino acid mutation associated with higher BGM-70 passaged viruses was absent in  UPM190BGMP7. However, it has another amino acid mutation at position D279N that back-mutated on continuous  BGM-70 cell propagation.
Bullying, Cheating, Deceiving: Teachers’ Perception of Deceitful Situations at School
Authors: Marksteiner Tamara , Reinhard Marc-André , Lettau Florian , DickhÃ¤user Oliver
Published: November 2023

Two studies investigated in which situations teachers (would) investigate whether a student was lying or telling the truth and how these situations were perceived. Results of Study 1 indicate that teachers (would) interview students when it comes to use of unfair means, aggressive behavior, theft, absence without permission, bullying, and vandalism, whereat deceitful situations with rather light consequences were most frequently described. Moreover, participants perceived the frequency of occurrence of all situations as lower for themselves compared to colleagues. In both studies, the use of unfair means, absence without permission, and bullying (over a longer period) were rated as most frequently occurring in everyday school life. Further, deception detection was perceived as being mostly important in situations with severe consequences. Study 2 also demonstrates that situations with light consequences are perceived as situations where it is of relatively less importance to make accurate judgments, avoid wrongful accusation, and detect misbehavior, as compared with situations with severe consequences. Overall, teachers perceive avoiding wrong accusation as more important than detecting misbehavior. Influences of teachers’ perceptions on their behavior are discussed.

This article examines the identity of pastors in dealing with conflicts of interest between pastors. It has become commonplace these days to increasingly hear of conflicts of interest between pastors which result in arguments, divisions, and leave deep emotional wounds. Through this article, we will be able to understand the relationship between the identity of pastors in dealing with conflicts of interest with fellow ministers as Christians. By using case study research methods in a qualitative approach, accompanied by data collection techniques through interviews, observation and documentation, then the data is analyzed by data reduction and data presentation. The results of the research found that the pastors were born again, had personal experiences with God that awakened faith, had theological education, and had fairly good knowledge of the Bible, however there was an identity that was not in line with the teachings of the Word. From a psychological aspect, it was found that some of the priests did not have a father figure, some had died, divorced, and some had been entrusted to other people. These elements then have a negative impact on the pastor's identity if they are not handled wisely.AbstrakTulisan ini mengkaji perihal jati diri pendeta dalam menghadapi konflik kepentingan antar pendeta. Menjadi hal yang biasa pada hari-hari ini dengan semakin sering mendengar konflik kepentingan antar pendeta yang mengakibatkan pertengkaran, perpecahan, dan meninggalkan luka hati yang mendalam. Melalui tulisan ini akan dapat mengetahui kaitan jati diri pendeta dalam menghadapi konflik kepentingan dengan sesama rekan sepelayanan sebagai orang-orang kristen. Dengan menggunakan metode penelitian studi kasus dalam pendekatan kualitatif, disertai teknik pengumpulan data melalui wawancara, observasi, dan dokumentasi, untuk kemudian data tersebut dianalisis dengan reduksi data dan penyajian data. Hasil penelitian ditemukan bahwa para pendeta didapati telah lahir baru, memiliki pengalaman pribadi dengan Tuhan yang membangkitkan iman, memiliki pendidikan teologi, dan memiliki pengetahuan Alkitab yang cukup baik, namun demikian terdapat jati diri yang belum seturut dengan ajaran Firman. Dari aspek psikologis ditemukan bahwa para pendeta didapati ada yang tidak memiliki figur ayah, ada yang meninggal, bercerai, dan ada yang dititipkan kepada orang lain. Unsur-unsur tersebutlah yang kemudian berdampak negatif pada jati diri pendeta tersebut jika tidak disikapi bijaksana.

The paper generally aimed to study the effect of the internal control system on the financial performance of church organization compassion centres in the Nyamagana district. Specifically, the study centred on three areas, namely, the control environment, control activities and monitoring. The study applied the principal/agency theory. Data were collected at once through close-ended questionnaires where a cross-sectional research design was fitted. The study’s unity of analysis involved 100 people (church leaders, compassion centre board members, personal coordinators, social workers, accountants, and auditors). A binary logistic regression was used to analyze the relationship between the internal control system (ICS) and financial performance (FP) of church organization compassion centres. The outcomes depicted that the control environment has a positive significant relationship with the FP of compassion centres (r=0.838, β=0.512, p=0.000). Moreover, control activities have a positive significant relationship (r=0.828, β=0.521, p=0.000), while monitoring has a positive significant relationship with FP of compassion centres (r=0.751, β=0.629, p=0.000).

Os estimulantes cerebrais são frequentemente utilizados por jovens estudantes que pretendem aumentar o desempenho cognitivo, mas também serem capazes de manter alerta e despertos por mais tempo. O objetivo do presente estudo foi caracterizar os hábitos de consumo de estimulantes cerebrais pelos alunos do Instituto Politécnico de Bragança (IPB), motivos e fatores associados. Realizou-se um estudo descritivo-correlacional, com 303 estudantes matriculados no IPB em 2018/2019, com amostragem não probabilística por conveniência. Para recolha de dados, utilizou[1]se um questionário online de autopreenchimento, com questões demográficas e comportamentais sobre o uso de estimulantes cerebrais. Para análise dos dados foram utilizadas estatística descritiva e inferencial através do teste de independência do Qui-quadrado, com um nível de significância de 5%. Os resultados revelaram uma média de idades de 23,2 anos (± 5,166) e predominância do sexo feminino (63,0%). A maioria dos participantes (54,1%) referiram que já consumiram algum estimulante cerebral, por autoiniciativa (81,7%), sendo o café (79,3%) e as bebidas energéticas (37,8%) os mais utilizados atualmente e o metilfenidato (1,8%) o menos utilizado. Os motivos de consumo mais referidos foram o aumento da capacidade cognitiva (32,1%) e a diminuição da fadiga e cansaço (20,0%). O consumo de estimulantes está associado ao sexo e ao ano frequentado, sendo mais frequente em estudantes do sexo feminino (69,5%, p=0,011) e a frequentar o 3º ano (29,9%, p=0,028). A utilização de estimulantes cerebrais por estudantes do IPB é uma realidade, sendo a cafeína e as bebidas energéticas as substâncias mais utilizadas, por autoiniciativa. As mulheres apresentam níveis de consumo superior aos homens e esta tendência manifesta-se também em estudantes de 3º ano. Considerando os resultados deste estudo, sugere[1]se promover o aumento da literacia em saúde e alertar para a utilização desregulada destas substâncias.

Human rights and freedoms is a topic that has been current, open and suitable for research since the beginning of civilization. This is because human rights and freedoms are the meaning and starting point of the social order. With man at the center, i.e. his needs and the creation of conditions for preserving the dignity with which he was born, human rights and freedoms are the subject of analysis by many scientific disciplines. The author will deal with the topic of the paper from the aspect of legal science, briefly introducing the readers to the concept and importance of human rights, and then he will focus on the presentation of the types of human rights. Classification is a theoretical issue that is extremely important for practice due to the organized, synchronized and chronological presentation of the rich body of human rights. The understanding of each individual human right is conditioned precisely by following their development paths, and that from the aspect of different initial criteria for their division. A theoretically well-addressed question is an excellent basis for its understanding, and thus its application in practice.
Identification of Fresh and Unfresh Fish Based on Eye Image Using The Self-Organizing Maps (SOM) Method

Published: November 2023

Fish is a common protein source and easy to obtain in Indonesia, but because of its high water content, fish quickly spoils. Fish freshness can be detected using several conventional methods, such as chemical analysis, biochemistry, microbiological analysis, and sensory examination. Another identification method involves observing the color of the fish's eyes. Fish identification is crucial before any further processing, ensuring that the fish's quality delivered to consumers remains high. To tackle the problem of differentiating between fresh and non-fresh fish, this research employs Self-Organizing Maps (SOM) as the primary methodology. This research focuses on identifying fresh and non-fresh fish using the SOM method, using actual data involving tilapia as the research object. The data includes eye images of new and non-fresh fish, and various procedures are required to obtain the desired data. This data is then used as training and testing data. The process continues with the preprocessing stage, which is a data modification process to improve performance in subsequent steps and feature extraction using HSV color histograms. Classification of processed data is carried out using the SOM method. Once completed, the identification results are displayed. This research produces a system for identifying fresh and non-fresh fish based on eye images using SOM, which achieves a good accuracy of 85.71%.
