The VIEW4 SCADA/EMS system is a basic operational management tool in RDC Belgrade and RDC Novi Sad. It is also planned to introduce the system into operational use in other regional dispatch centers (Bor, Kruševac and Valjevo) as well as in the National reserve dispatch center. Additionally, the system serves as a backup tool for operational management and planning in the National dispatch center. Within the EMS (Energy Management System) subsystem, there is Dispatcher Power Flow application, which allows dispatchers to check the security of the power system in the case of planned or unplanned management actions, including disruptions in the transmission system. During the use of this application, it was concluded that implementing a series of improvements in the user interface would be useful to increase its intuitiveness and clarity of presentation of calculation results. According to the analysis of user requirements, it is necessary to create a completely new user interface for the application and integrate it into the existing HMI (Human-Machine Interface) of the VIEW4 SCADA/EMS system. This paper provides a functional description of Dispatcher Power Flow application and presents the realized graphic displays. Furthermore, the paper discusses plans for the application's further development.

The project of remote control brings a technological improvement to the process of management and exploitation of the transmission system of Serbia in accordance with the latest European trends. The most noticeable application of remote control in regional centers is changing the appearance of the center itself. They are equipped with video walls that, with modules for the synoptic display of the network, build a unique wall that enables the operational staff of the regional control centre to fulfill the main task : effective risk reduction in management processes. A unique software solution for camera management enables monitoring of the elements specified in the SCADA system on the video wall in real time from different angles. The video wall in the control centers is equipped with six panels, so each element of the high - voltage plant can be viewed with six different cameras, that is, from six different angles. The cameras themselves have specific protective modules, anti-fog solutions, so in conditions of reduced visibility, the camera enables high-quality functional video surveillance. Thermal modules in individual cameras allow the temperature of each element of the monitored plant or even a part of it, to be precisely determined in real time by operational staff.The application software allows the center's operational staff to control the position of each individual camera in the monitored objects with framing changes, zooming and linear perspective changes. It is also possible to archive photos and videos according to the selected model. The system offers a large number of facility monitoring capabilities and functions, but this very capability should initiate limitation to those functions performed by the regional transmission system control center. We are still practically dealing with the identification of those new functions that can be an auxiliary tool in the basic task of the regional control center. When the staff of the center supervises an unoccupied facility, it is unquestionable that video surveillance conceived in this way brings a lot of technological possibilities, but are they sufficient to implement dispatching actions as when they are initiated by information from operators on the spot? Currently, such actions are limited, but new aspects of application are noted: exploitation, fire protection... Other functions should be left to be performed by some future remote control plant maintenance centers. We have very positive experiences in the application of these solutions in our previous work. Users still have to study the application of the possibilities offered by the system, to modify it according to their requirements and thus improve video surveillance in the function of plant management.
Out-of-time Experiences in Four Iconic Twentieth Century European Modernist Novels Including Zeno's Conscience: A Psychosynthetic Analysis
Authors: Tóth-Izsó Zsuzsanna
Published: December 2023

On the centenary of the release of Italo Svevo's Zeno's Conscience in 1923, it is opportune to explore the renowned psychoanalytical novel from a fresh perspective—one that not only refrains from contradicting the traditional interpretation but also enhances and complements it. The psychosynthetic approach that I intend to employ in analyzing the transpersonal experiences depicted in "Zeno's Conscience" will demonstrate its efficacy as a valuable tool for attaining a more profound comprehension of the protagonist's—potentially reflecting Svevo's—complex personality. As Assagioli, the founder of psychosynthesis, articulates, it delves into the concept of multiple minds. In this first article of the two, transpersonal experiences of Zeno are identified, followed by descripting similar experiences in three iconic 20th-century European modernist novels, Ulysses, Time Regained and The Man Without Qualities, by using appropriate quotes. The common main feature of these four novels is the steadily flowing time, the natural medium of the "horizontal" processes of personal psychosynthesis (Chronos). My focus here is, however, on the detectable – although rather sporadic – "vertical" episodes of transpersonal psychosynthesis, which are, in a sense, "out of time" (Kairos). Moreover, Zeno's transpersonal experiences are compared with that of the characters’ of the selected three iconic modernist novels.
MONETARY POLICY AND MISERY INDEX IN NIGERIA
Authors: George-Anokwuru Chioma Chidinma
Published: December 2023

This study investigated the influence of monetary policy on the misery index in Nigeria. The data for the study were collected from the numerical bulletin of Nigeria’s apex bank spanning 1985 to 2019. The misery index was measured by the sum of unemployment, inflation, and lending rates minus the percentage change in Real Gross Domestic Product per capita. The Augmented Dickey-Fuller test and Autoregressive Distributed Lag - ARDL model were the main tools of analysis. The outcome of the unit root test indicated that the variables were stationary at order zero and one, which fulfilled the requirement to employ the ARDL Bounds testing method. The ARDL Bounds test revealed the presence of long-run association among the variables. The results revealed that monetary policy rate and exchange rate have a significant relationship with the misery index in Nigeria during the period of study. However, there is no significant relationship between the broad money supply and the misery index in Nigeria during the period of study. The study concluded that though monetary policy has the potential of reducing the misery index in Nigeria but it has not been well managed to reduce the misery index in Nigeria during the period of study. That is, monetary policy has not been effective in reducing the misery index in Nigeria during the period of study. Based on these findings, the study recommended that monetary authority should adopt the monetarists’ ‘monetary rule’ whereby the money supply is increased at a rate equal to the potential annual growth rate of the Gross Domestic Product. The monetary authority should also evaluate her interest rate policies to stimulate investment, increase output of goods and services, employment opportunities and reduce the poverty and misery index in the country. That is, make the financial sector to be strong to provide credit at lower interest rates which in turn will increase investment, output of goods and services, employment opportunities and reduce the poverty and misery index in Nigeria. The authority should maintain a managed floating exchange rate system to redress the problem of exchange rate variation in order to reduce the misery index in Nigeria.

Authors: Achola Eunice , Ombok Benjamin , Kiganda Evans
Published: December 2023

Literature reveals inconsistencies on factors influencing the financial sustainability of local NGOs, with some suggesting such factors as income diversification, incomes from local and external donors as well as own income-generating activities, while others opine that continued external donor funding is required for sustainability. Evidence also shows that for the period under review, the financial growth of the NGOs, as critical vehicles of welfare development in the region has been fluctuating since 2010, but with a declining trend from 2019 to 2022. The purpose of this paper is to establish influence of the financial sustainability on the financial growth of non-governmental organizations in the Lake Region Economic Block- Kenya. A cross-sectional research design is adopted on a sample size of 220 respondents from whom both primary and secondary data were obtained and analyzed using independent samples t-test, one-way ANOVA, correlation, and regression. Guided by the Resource Based View Theory, the results yielded a significant  change of 0.033; from 73.7% to 77% after moderation; implying that financial sustainability has a significant moderating effect of 3.3%. The findings of this study are invaluable for innovative and sustainable financial decisions by NGOs, and also scholars and policymakers on matters of revenue growth.

Authors: Cole Princess G. , Castro Reynaldo C.
Published: December 2023

This study investigated the mediating effect of service performance on the relationship between job satisfaction and turnover intention of BPO workers in Davao City. In order to do so, this study employed the quantitative research design using the descriptive and correlational method via mediation analysis. Using proportionate stratified random sampling, primary data were gathered through the use of online survey questionnaires addressed to 373 respondents working in selected BPO companies in Davao City. In addressing the hypotheses of the study, correlation analysis using Pearson product-moment correlation and mediation analysis using Sobel z test were used. The level of job satisfaction and service performance was very high among BPO workers, while the turnover intention was low. Results also revealed job satisfaction to have significantly predicted turnover intention and service performance which satisfied the ground for mediation. However, service performance did not significantly predict turnover intention. Further analysis through the Sobel z test confirmed that the mediating effect of service performance on the relationship between job satisfaction and turnover intention is not significant.

WHAT DOES THE ONLINE CHAT BOX TELL: A MIXED STUDY OF STUDENT PARTICIPATION INDICATED BY ONLINE CHAT DATA AND OTHER VARIABLES IN AN ONLINE ENGLISH COURSE
Authors: Huang Qiang
Published: December 2023

Student participation is essential to both teaching and learning, especially in the online instruction mode. The present study aims to examine student participation and their relations with other variables such as learning outcome and teaching performance in a university English course online. Participants were 84 sophomores of English Education majors at a university who learned an English course on an online learning platform. Both qualitative data from the chat box of the online learning platform and quantitative data of students’ final scores and their scores of course evaluation were employed. Follow-up semi-structured interviews were also conducted to provide further insights into the findings. Results showed that student participation indicated by the online chat data was extensive and active, with all participants engaged and an average of 112 messages sent per student over the semester in the online English course. Further correlational analyses found that student participation was not significantly correlated with either learning outcome indicated by students’ final scores or teaching performance indicated by their course evaluation scores. However, interview data revealed that online chat boxes had contributed to lower-risk and more active online participation in several ways including attenuating participation apprehension, improving concentration on instruction and building a learning community. Implications of the findings were discussed and suggestions for future research were provided.

Published: December 2023

The purpose of this research is to analyze the contribution of coordination, balance, flexibility, arm muscle strength to the kizami-gyaku zuki punch of female athletes. The background to this research is from observations of the qualifying round at the 2023 National Sports Week (PON), on average female athletes earn points from punches. This research is an analytical survey to test the contribution of the independent variables. The sample was 50 female athletes with characteristics namely age 19.8±1.2 years, training experience 8.3±0.6 years, weight 50±1.5 kg, height 160.4±1.5 cm. The tests carried out included coordination using the Hand-Wall Toss Test, balance using the Modified Bass Test of Dynamic Balance, flexibility using the sit and reach test, arm muscle strength using push up for 1 minute, kizami-gyaku zuki punches using a punching bag during 30 seconds. The results of this research show that coordination, flexibility, and arm muscle strength have an effect on kizami-gyaku zuki punches. However, balance has no effect on the kizami-gyaku zuki punches. Adjusted R Square results, the contribution from coordination (r = 0.341) or 34.1%, balance (r = 0.235) or 23.5%, flexibility (r = 0.490) or 49%, arm muscle strength (r = 0.465) or 46.5%, contribution overall against kizami-gyaku zuki punch (r = 0.674) or 67.4%. The conclusion is that it is important for trainers, athletes, and sports karate academics to focus on these four physical components so that the kumite abilities of female athletes can be improved. However, it is important to train in other physical components, such as endurance, technique and tactics and mental. Future research is expected to add variables or update the types of tests used in this research.

DURATION, INTENSITY, AND CONTENT OF PHYSICAL EDUCATION CLASSES IN A REPRESENTATIVE SAMPLE OF CHILDREN ATTENDING 5TH AND 6TH GRADES OF PRIMARY EDUCATION
Authors: Tambalis Konstantinos D.
Published: December 2023

Physical Education (PE) is an educational process that develops the knowledge, skills, attitudes, and well-being of children, through games, sports, exercises, etc. The study aimed to evaluate the parameters of physical activity (PA) during PE class and to investigate the content, time, and intensity of children who participated in PE class, by gender and obesity status. PA and PE items were assessed by a self-administrated PA checklist, proper for children. A representative sample of Greek boys and girls aged 10 to 12 years (N=3195) participated in the study. Boys incorporated higher levels of moderate to vigorous PA (MVPA) (62 ± 45 min/d) than girls (27 ± 33 min/d, p<0.05). Students, who participated in PE classes, presented increased total PA (139 ± 2 vs. 116 ± 51 min/d, p<0.05) and MVPA (62 ± 38 vs. 40 ± 32 min/d, p<0.05), and a higher percentage of them met (77 vs. 66%, p<0.05) the recommended PA levels than those who didn't participate. Among participants in PE classes, boys reported higher time of MVPA than girls (19.4 ± 23.9 vs. 10.3 ± 17.7 min/d, p<0.05), while girls had more time in light PA as compared to boys (15.1 ± 18.1 vs. 20.5 ± 21.3 min/d, p<0.05). There were no significant differences between normal-weight and overweight/obese participants in PE classes neither in PA sub-components (total PA, LPA, and MVPA) nor in sports/games did they participate. PE classes play a significant role in students' levels of PA, especially for overweight/obese children.

CLIMATE CHANGE AND ENVIRONMENTAL DEGRADATION: A SERIOUS THREAT TO GLOBAL SECURITY
Authors: Rahman Mohammed Mahafuzur
Published: December 2023

Climate change and environmental degradation have been considered global issues apart from being graded as emerging issues. Climate change is a significant trend because of the adverse conditions witnessed already, and the implications likely to result when the situation is not addressed. The main causes of climate change and environmental degradation are human activities such as burning fossils, deforestation, and human settlement. The decline of the environment has led to national and international security risks as it is linked to food shortages, climate change calamities such as floods or famine, drought, loss of lives, soil erosion, and crop failure due to limited water resources. Countries have had to come together to find lasting solutions to climate change and the decline of the environment as it has raised concern across the world. Besides, there have been solutions that have been agreed by researchers that would minimize the risks of climate change and the decline of the environment, such as afforestation, avoiding the use of plastics, and recycling of waste products. Therefore, environmentally friendly activities have been encouraged in countries across the globe.

BASIC CHARACTERISTICS OF NGUYEN AN NINH’S POLITICAL IDEOLOGY AND THE MEANING OF THAT IDEOLOGY
Authors: Nhi Nguyen Thi Lien
Published: December 2023

The late 19th and early 20th century was a special historical period for the Vietnamese people, a period of transformation that changed the nature of society. Our country was invaded by the French colonialists and became a semi-feudal, colonial country. It can be said that Nguyen An Ninh was a typical thinker of Vietnam in the late 19th and early 20th centuries. He introduced political ideas consistent with the reality of the Vietnamese revolution in this historical period. Based on an overview of the basic contents of Nguyen An Ninh’s political ideology, this study aims to clarify the basic characteristics of Nguyen An Ninh’s political ideology such as (i) Deep nationality in Nguyen An Ninh’s political ideology; (ii) Vivid practicality in Nguyen An Ninh’s political ideology; (iii) Nguyen An Ninh’s political ideology represents the transition from bourgeois-democratic ideology to Marxism-Leninism. On that basis, clarify the values of that characteristic in Vietnam’s revolutionary process.

PLAY-INTEGRATED TEACHING AND LEARNING IN BENEFICIARY SCHOOLS OF THE RIGHT TO PLAY LEARNING THROUGH PLAY PROJECT IN THE SAVELIGU DISTRICT OF NORTHERN GHANA
Authors: Soma Abdallah , Kissiedu Kwaku
Published: December 2023

This study examined kindergarten (KG) teachers’ implementation of play-integrated teaching and learning in beneficiary schools of the Right To Play (RTP) learning through play initiative in the Saveligu District of Northern Ghana. An intrinsic case study design was adopted. Thirty KG1&2 teachers were purposively selected and willingly took part in this study. Semi-structured interviews and non-participant observations were used to collect data. The data were manually coded, summarised, and analysed using a deductive thematic approach to qualitative data analysis. The study identified three groups of teachers with three different ideologies and practices. They all admitted that play was an avenue for children to have fun, learn, and develop holistically. However, they approached play-integrated teaching and learning differently. While some discouraged the practice, others encouraged it partially and some other teachers embraced it fully. These disparities in teachers' views and practices of play-integrated teaching and learning revealed some infrastructural and curricular deficits in Ghanaian KG education. The study recommended that the Ghana Education Service (GES) should address the infrastructural deficit identified in most KGs in the Saveligu District and invest more in play-integrated teaching and learning. Also, the National Council for Curriculum and Assessment (NaCCA) should revise the current KG curriculum to include explicit instructions on the use of play-integrated pedagogies in KG.

ESTABLISHING THE EVOLUTION OF WEST NILE VIRUS OUTBREAKS IN ROMANIA BY USING CLIMATIC SCENARIOS
Authors: MIRON Liviu Dan , IVANESCU Larisa Maria , MINDRU Raluca , MATIUT Simona , MARTINESCU Gabriela Victoria , BODALE Ilie
Published: December 2023

West Nile virus (WNV) is a re-emerging zoonotic pathogen that represents a threat to both animal and human health. It is difficult to estimate the impact of WNV in the future, although many of the climatic factors influencing its spread have been identified. In this study, we used bioclimatic indices to estimate those periods that favour the growth of vector mosquito populations and the incubation periods for the virus. To this end, we studied the climatic changes in the Romanian regions where cases of WN infection have been reported. Simulations were carried out for 2100 based on long-term scenarios. Identifying the bioclimatic conditions which can cause WNV outbreaks in Romania is necessary to anticipate and thereby prevent future epidemics. However, no extraordinary weather events were registered in the years with WNV outbreaks which could explain such a high number of cases. Thus, in the High Scenario (which will occur if actions to control (GHG) gas emissions are not taken or implemented effectively), the hatching period is extended until November, with the risk that adult mosquitoes are active throughout the year, ensuring a high survival rate of the virus within mosquitoes. In addition, in the High Scenario, the transmission period of the virus is extended from April to October, which underlines the need to establish monitoring and control programmes for both mosquito populations and the spread of the virus among the animal and human populations.

The current study was carried out at Rezu Khal to determine the ideal area for seaweed farming. Additionally, this investigation uncovered species of commercially productive and lucrative seaweed. Temperature, salinity, pH, dissolved oxygen (DO), conductivity, and Formazin Nephelometric Units (FNU) of surface water ranged from 20.9 to 26.2°C, 24 to 26.2‰, 6.45 to 8.5, 92 to 105%, 33,256 to 64,267 µS/cm, and 11.1 to 42.8, respectively. Phosphate-phosphorus concentrations in surface water were 2.6–7.6 mg/L, 0.04–0.12 mg/L for nitrate-nitrogen, 0.002–0.04 mg/L for nitrite-nitrogen, 0.15–0.83 mg/L for silica, and 0.13–0.28 mg/L for ammonia. Three seaweed species (Gracilaria lemaneiformis, Hypnea musciformes, and Sargassum oligocystum) were cultivated in the selected areas. Two methods (net and long-line) were used for the culture. In this study, 15–20 kg of G. lemaneiformis were harvested every 15 days using the net method. H. musciformes gained 4 to 12 kg every 15 days. Although S. oligocystum thrived nicely, it was challenging to maintain its viability. The findings of this study indicate that seaweed farming is feasible and coastal residents may participate in seasonal income-generating endeavours in coastal waters.

Methods: A web-based cross-sectional survey was undertaken in July-August 2022, using google forms. The respondents were assessed for socio-demographics, and the level of stress experienced over the previous month. Ten-item self-reported perceived stress scale (PSS) was used to assess stress levels analysis. Descriptive statistics and logistic regression analysis were used.
Results: A total of 1214 respondents, aged ≥18 years were included in the survey. The majority were females (60%). The mean PSS score of this population was 21.95 ±6.09. More than half of the respondents reported moderate levels of stress (68.5%), while 23% registered high levels. A significant association was demonstrated between stress levels and variables age, gender, and residential area. Respondents below the age of 40 years (OR 1.936, 95% CI, 1.365-2.748, P<0.001) were more likely to report higher odds of having increased PSS scores, while men (OR 0.640, 95% CI, 0.491-0.835, P=0.001), and those without children (OR 0.556, 95% CI, 0.409-0.756, P<0.001) had significantly lower odds of reporting PSS.
Conclusion: Respondents experienced moderate to high levels of stress during the financial crisis in Sri Lanka. Higher stress was predicted by younger age, female gender, and having children. The results highlight the urgent need for stress management interventions to boost resilience and improve psychological well-being in this situation.

Flower cultivation has increased nationwide. Currently, species of the Dahlia genus (known colloquially as Dahlias) are grown for ornamental purposes, with central Mexico having the highest production rate. Due to its importance, we sought to evaluate the effect of three different methods of cultivation (shade net, greenhouse, and open field) on the growth and development of four dahlia varieties in Saltillo, Coahuila, Mexico. The experiment was carried out at the Horticulture Department of the Universidad Autónoma Agraria Antonio Narro. Tuberous roots of four D. pinnata varieties were sown directly into the soil and covered with mulch. The shade netting production environment proved to be the best in production, with the best results in plant height, stem diameter, number of leaves, and days to flowering. The highest-performing cultivar was the Antje variety. On the other hand, the Antje variety (cultivated under shade netting) had the longest flower stalks, the Boy Mick variety (cultivated in the greenhouse) had the heaviest flowers, and the Canby Centennial variety (cultivated in open field) had the flowers with the thickest stalks. The results show that Dahlias can be grown in northeastern Mexico because the area meets suitable conditions for crop development and production.

Based on the results of pre-observations in class and the results of informal interviews with English teachers at SMP Negeri 11 Palu several months ago, several experiences revealed that teachers do not yet have a clear model of how to synchronize methods and approaches to suit the students’ needs, especially teaching methods and techniques that suit students' needs to overcome the inability to understand and use 'English Finite' appropriately and correctly according to the procedures for using a sentence in English. Students experience difficulty in using 'English Finite' when practicing speaking and writing. Therefore, the aim of this research is to reveal and prove that through the 'MAMA' type cooperative learning model, students can improve their mastery of 'English Finite' in everyday English practice. This research is experimental research to test a 'MAMA' type cooperative learning model. The research sample was 18 students from class VIII A as the control class group and 20 students from class VIII C as the experimental class group, at SMP Negeri 11. Furthermore, treatment or application of the 'MAMA' type cooperative learning model was only given to the experimental group, while the control class underwent the application of conventional learning. Data collection was carried out by giving tests to both groups. Based on the pre-test results, the experimental group was 51.5, while the control group was 50.83. Furthermore, after implementing MAMA type learning, the experimental class was given a posttest and the result was 65.78, while the control class went through conventional learning and the posttest result was 58.23. This indicates that the increase in the 'mean score' of the experimental group was much higher than that of the control group. It can be concluded that by implementing 'MAMA' type cooperative learning can improve students' ability to write precise and correct English Finite in making descriptive texts.
Childhood Obesity and the Risk of Hypertension in the Caribbean Region: A Narrative Review
Authors:   ', Md, Mph Feimatta Immah Sowa,
Published: December 2023

Childhood obesity is a rising epidemic affecting both developed and developing countries worldwide. In the Caribbean, estimates of obesity in children are noted to be above the predicted global values, and evidence suggests that the rise in obesity levels is due to environmental influences in dietary practices and physical inactivity. Methods: This review aims to determine the effects of childhood obesity and the associated risks of developing hypertension in the Caribbean population. Research articles were identified using computer-based search engines such as Google Scholar, PubMed, ScienceDirect, World Health Organization (WHO), and Caribbean Public Health Agency (CARPHA) databases. Researched articles with various study designs were then thoroughly analyzed to extract detailed information about obesity in childhood and the risks for hypertension in later years. Results: Rapid weight gain in infancy and high (body mass index) BMI levels in childhood are associated with higher blood pressure values and increased cardiovascular risk. Additionally, direct baseline elevation of blood pressure (B.P.) measurements, noted in obese/overweight children compared to their nonobese counterparts, confirm the hypothesis that childhood obesity is positively associated with hypertension. Conclusion: This review article provides detailed facts about childhood obesity, the risk for hypertension, and improvement recommendations and calls attention to the health implications of obesity-related hypertension in children if left untreated.
