Este trabalho faz uma descrição de casos práticos de uma concessionária de distribuição de energia elétrica referente à aplicação de estudos com a simulação de manobras em linhas de subtransmissão (LTs) utilizandodiferentes equipamentos de manobra. Analisa-se o caso de cargas radiais que são alimentadas por LTs de diferentes subestações, mas que podem ser operadas em circuitos com duas diferentes fontes de alimentação, visto que alguns desligamentos programados em LTs envolvem muitos consumidores, o que repercute no desempenho técnico-operacional da empresa. Assim, por meio do software ATPDraw (Alternative Transient Program) serão modeladas manobras que envolvem chaves seccionadoras (manuais e motorizadas), disjuntores e circuit switchers de 69 kV, com o objetivo de analisar os transitórios eletromagnéticos e os níveis de continuidade de energia evitando-se interrupções junto aos consumidores, que estão mais rigorosos quanto à qualidade do fornecimento de energia elétrica. Com isso, pretende-se apresentar no software ATPDraw, através da utilização de diferentes equipamentos de manobra em sistemas elétricos de potência, os ganhos em termos de desempenho técnico-operacional que alguns desses equipamentos apresentam para uma empresa distribuidora de energia elétrica.
Adaptive Perturb and Observe with Simulated Annealing for the Maximum Power Point Tracking of Photovoltaic Modules in Multiple Shading Scenarios
Authors: M. R. Praxedes Rafael , S. Barros Luciano , A. Siebra Clauirton , M. V. Barros Camila
Published: February 2021

This paper proposes a method that combines the Adaptive Perturb and Observe (Adaptive P&O) and Simulated Annealing (SA) optimization approaches to identify the global maximum power point in photovoltaic (PV) modules. This identiffication is critical to enable that such modules can deliver their maximum power to the utility network, considering different shading conditions. The Adaptive P&O method combines fast convergence and low steady-state oscillations, but it tends to return local rather than global maximum power values. Thus, it does not ensure the total efficiency of the modules. The SA approach is used to avoid this P&O limitation, creating a hybrid approach that explores the best features of each method. In order to test the proposed method, it has been applied to the Canadian Solar CSP-320 module under multiple shading by means of Matlab/Simulink simulations. Firstly, the module model was validated from its datasheet information, then, it was submitted to different shading conditions. Under these conditions, the proposed method converged to the maximum global power.

Authors: Nardi Zancan Diogo , Pinheiro Bernardon Daniel , Jantsch Lucas André
Published: February 2021

O aumento contínuo do consumo de energia elétrica no país e a eminente crise energética vivida, as concessionárias foram obrigadas a recorrer às fontes de energia com custos elevados, repassando este valor aos clientes. Preocupados com a instabilidade do setor de energia, muitos consumidores vêm procurando alternativas energéticas para reduzir os impactos econômicos. A microgeração distribuída é uma alternativa relativamente simples e vem sendo amplamente utilizada por consumidores residenciais. O modelo conhecido como net metering, utilizado para regular os sistemas de microgeração de energia no país, em conjunto com o sistema de tarifa monômia, pode gerar um subsídio cruzado entre consumidores da mesma distribuidora. Esse fenômeno tem gerado discussões ao redor do mundo, envolvendo a aplicação de uma tarifa diferenciada chamada tarifa binômia aos microgeradores, de forma a cobrir os custos fixos das distribuidoras referentes a essas unidades agregado ao custo da demanda. Dado o cenário atual e a eminente necessidade de reavaliação do sistema tarifário devido as novas tecnologias implantadas neste, no presente artigo será analisado uma metodologia em que o consumidor possa visualizar até que ponto é positivo a implantação de uma tarifa binômia para sua residência, adeptos ou não adeptos ao sistema de microgeração de energia.

This paper presents an experimental and theoretical investigation into water condensation and corrosion under noncorrosion product forming conditions at the top of the line in a static, CO2 environment. An experimental test cell is developed to measure droplet lifetimes, condensation rates, as well as in situ and integrated corrosion rates (using miniature electrodes and mass loss specimens, respectively) as a function of the surface and gas temperatures when the gas flow is dominated by natural convection. Experimental results show clearly that the water condensation rate is not very influential on the corrosion rate at low surface temperatures (Ts) (particularly below 25°C) but becomes much more important at higher surface temperatures (>40°C). These findings are summarized in a new empirical correlation for the top-of-line corrosion rate as a function of the condensation rate and surface temperature. A model for condensation at the top of line for static, buoyancy-driven conditions is also presented and is shown to predict dropwise condensation rates accurately for a range of experimental conditions. The developed miniature electrodes for in situ electrochemical measurement are shown to provide an accurate interpretation of the transient response in general corrosion behavior by giving real-time corrosion rates to complement the mass loss measurement.

Published: February 2021

Objectives. The study aimed to explore which barriers adult people perceive when deciding whether to enter psychotherapy and how these barriers influence their decision to start psychotherapy. Sample and setting. The sample consisted of 392 adult respondents who considered entering individual psychotherapy during the last five years. They completed a questionnaire on perceived barriers to entering psychotherapy, the phase of decision-making, and the severity of psychological symptoms. Hypotheses. This was an exploratory study with the following questions: a) What is the perceived importance of specific barriers to entering psychotherapy? b) What groups (principal components) of barriers to entering psychotherapy can be identified? c) What is the relationship between the perceived importance of barriers and the decision to enter psychotherapy? Statistical analysis. The number of barriers was reduced using PCA. The relationship of the decision-making phase to other variables was explored via multinomial regression analysis. Results. The most severe barrier to entering psychotherapy were price, reluctance to express emotions in front of others and the assumption that one’s problems were not as severe as the problems of people in psychotherapy. Respondents who decided not to enter psychotherapy were older, expressed more distrust of psychotherapy, and perceived it as more stigmatizing than those who contacted a therapist. Respondents who decided to enter psychotherapy (but who had not contacted a therapist) had less severe symptoms and perceived psychotherapy as more stigmatizing than those who contacted a therapist. Study limitations. Limits of the study include a non-representative sample and the time window used for the retrospective rating of symptoms and barriers.

Authors: Tuble Ruvy M. , Bayoneta Ma. Johanna Ann R.
Published: February 2021

This descriptive research examined the state of public libraries in Negros Occidental as to its compliance with RA 7743; its performance based on standard requirement; and implementation of greening practices to 31 administrators and 379 users. Findings revealed that most of the provisions of the law were not complied as indicated by the number of municipalities without libraries, the appointment of a non-professional librarian, and the inadequacy of budget allocation.  Likewise, assessors find their performance as good but distinctively rated IT facilities and services as poor. In the implementation of sustainable practices, administrators rated it great, while users find it to a moderate extent. The challenges encountered by assessors conveys a clear message that public libraries are striving to fulfill its philosophy of existence. Thus, broader knowledge and understanding of local authorities and the community of the vital role public library plays in nation-building shape its future.
The Prevalence of Adverse Childhood Experiences in Payatas, an Urban Poor Community in the Philippines
Authors: Ferrer Yanro Judd C. , Moore Roy
Published: February 2021

This paper aimed to determine the prevalence of Adverse Childhood Experiences (ACEs) in Payatas, an urban poor community in Quezon City, Philippines. In total, 260 people were surveyed in two areas of Payatas. The results of these surveys were then compared with existing ACE Surveys in other communities. Results found that ACEs were reported at significantly higher levels than in existing surveys, which were typically made of Middle-Class populations. The discrepancy grew at higher ACE Scores. Moderate childhood trauma, ACE Scores of 4 or more, was reported as two to five times more common in our Payatas populations than in the existing survey populations. Severe childhood trauma Scores are less available; however, these trends appear to grow at higher ACE Scores. These results suggest that ACEs are far more common in urban poor communities. That ACE Scores are higher in poorer communities is not a surprising finding. However, the scale of the problem is highly significant. As ACEs are a major root cause of many social problems, including, but not limited to, addiction, teen pregnancy, domestic violence, depression, attempted suicide, and drug abuse, it does indicate a strong area for effective support. The potential for improving the well-being, quality of life, and life expectancy through this framework is large, provided appropriate investment is made in these communities.
An Exploratory Study on the Practice of Pagsasanto by Openly-Gay Santeros
Authors: Piamonte Samuel Brando H. , Quintos Mark Anthony M. , Iwayama Minami O.
Published: February 2021

This exploratory study was conducted to inquire into the experiences of gay santeros – those who take care of religious statues or imahes that are used for Catholic religious activities. The study looked into the entry of the santeros to the practice of pagsasanto, their access to the imahe, their reasons for entering and maintaining the practice, and the benefits that they perceive to derive from it. Through conducting interviews with openly-gay santeros, it was found that early exposure to their religious family, school, and local community influenced them into entering the practice of pagsasanto. On access to the imahe, the participants were either owners of the imahe through purchase, donation or inheritance, or caretakers of the imahe through entrustment by their religious networks. On reasons for entering and maintaining the practice, it was found that such was conducted and maintained for egoistic reasons, self-expression, legacy, or spirituality. Lastly, it was found that advantages on health and subsistence, personal development, and social rewards were the perceived derived benefits from the practice of pagsasanto. These findings suggest implications pertaining to the dynamics of religiosity and non-normative gender identity in the Philippines where the Church finds willing caretakers among gay Catholics while gays find an avenue for the expression of gender identity and creativity in the task given to them.
Economic and Social Implications and Challenges of Relocation of Street Vendors in a Highly Urbanized City
Authors: Bayatan Joselito T. , Palic Anabelle S.
Published: February 2021

On July 29, 2019, the Department of the Interior and Local Government (DILG) issued Memorandum Circular 2019-121 (DILG MC 2019-121), ordering the local chief executives to clear roads, sidewalks, and rights-of-way of obstructions. The descriptive-comparative research design was used to describe the economic and social implications of their relocation. A validated and reliability-tested survey questionnaire was used to gather data from 197 displaced vendors peddling in the downtown of a highly urbanized city. The findings of the study showed that the relocation of the displaced vendors did not change their economic conditions in terms of their average monthly sales, expenses, and income, but significantly differ when grouped and compared according to their age, educational attainment, family size, years of vending, and types of merchandise. Likewise, their social well-being did not change in terms of education and health and significantly differ when grouped and compared according to the aforementioned variables.   Moreover, the major challenges faced by the relocated vendors were as follows: their means of livelihood is very difficult; not enough financial support is given during their relocation; limited space/trading site; and lack of access to the credit facility. The local government may utilize the study to implement a transit-oriented development of these vendors.

The consumption of plant-based food products instead of animal-based products tends to increase worldwide which can be caused by the global expansion of alternative food products. The article's objective is to investigate the perception of plant-based milk analogues by real and potential consumers and determine the prospects of increasing their assortment. The assortment of plant-based analogues of milk and products made thereof is analyzed. A projection of the almond milk sales was made as one of the most effective product categories. Questioning of consumers conducted to investigate consumer treatment of plant-based milk analogues. The survey covered 436 respondents, of which 37.7% consume plant-based milk regularly and 47.7% of respondents consume this product occasionally. About 15% of respondents have never consumed it. The results show that experimenting with diets and health concerns more often young people (under 30 years of old). Plant-based milk was consumed by men (47.6%) and women (52.4%). Prices for plant-based milk analogues are too high, and its reduction will increase the sales of this product according to respondents. The taste is one of the crucial factors in choosing plant-based milk analogues by respondents. By taste-based preference, the largest shares are with almond milk (20.4%) and oat milk (15.3%). At the same time, 16.2% of the respondents have no preference regarding plant-based milk analogues. It was found that using the titles of traditional milk products for naming plant-based milk analogues is not troublesome for most of the respondents. The derived figures give evidence that consumers, not being sufficiently aware of the origin of plant-based milk analogues, do not understand the differences between traditional products and their plant-based analogues.

Published: February 2021

The present study evaluated the microbiological, chemical, and organoleptic aspects of irradiated fresh fish and its products to extend their shelf life. Fresh fish and its products were irradiated at three doses (1.5, 3.0, and 4.5 kGy) used for preservation to study the effects of irradiation on their microbiological properties, fatty acid composition, and organoleptic properties. Irradiated fresh bolti fish, smoked herring, and smoked mackerel were evaluated microbiologically, chemically, and organoleptically. Radiation treatment not only reduced the counts of aerobic bacteria, fecal streptococci, molds, and yeasts but also destroyed all the Staphylococcus aureus cells, improving the hygienic quality of the fresh and smoked fish samples. Irradiation increased the peroxide, acid, and thiobarbituric acid values, but they remained within acceptable levels. No new fatty acids or other artifacts due to irradiation were observed. Irradiation of 4.5 kGy greatly reduced the organoleptic quality scores of fresh bolti fish, indicating that the optimum radiation dose for this fish was 3.0 kGy. Smoked herring and mackerel could be irradiated with up to 4.5 kGy without adverse effects on their organoleptic properties.

Background and objectives: Sickle Cell Disease is a painful genetic disorder characterized by abnormal hemoglobin that affects 1-in-365 African American births. Individuals with Sickle Cell Disease often experience frequent hospitalizations, resulting in 30-day readmission rates 2.5 times higher than those without Sickle Cell Disease. Discharge education programs have shown to improve 30-day readmissions and improve health outcomes.Methods: This advanced practice nurse-led initiative incorporated components of the Re-Engineered Discharge (Project RED) protocol, which included patient and medication education, specific discharge teaching, and post-discharge follow-up phone calls over a 12-week period. A pre/posttest design was used to evaluate 30-day readmission. Analyses included descriptive statistics and Fisher’s exact test.Results: Of the (N = 10) participants, eight (80%) were female, with a mean age of 31.08 (± 4.33) and all were African Americans. Although not statistically significant, there was a 48% reduction in 30-day readmissions rates between the pre/post intervention periods.Conclusions: The utilization of an enhanced discharge teaching protocol is a practical solution to increase patients’ readiness for discharge and to reduce 30-day readmission rates. Project RED discharge teaching protocol is an effective strategy for nurses to employ to improve patient outcomes and quality of care for persons with Sickle Cell Disease.

This research aims to identify science and mathematics teachers’ attitudes towards integrating Information and Communication Technology (ICT) in their educational practice through applying the Unified Theory of Acceptance and Use of Technology (UTAUT). A questionnaire instrument was developed based on the constructs of the UTAUT (performance expectancy, effort expectancy, social influence and facilitating conditions) and attitudes scale. The study sample consisted of a group of mathematics and science teachers in governorate of Ma’an. The participants were randomly selected. Descriptive and regression analysis were used to analyze the data. The results showed the attitudes of science and mathematics teachers towards integrating information and communication technology in the educational process were high and positive. In addition, the results showed that science and mathematics teachers had positive and high perceptions of integrating information and communication technology in the educational process in all dimensions (performance expectancy, effort expectancy, social influence, and facilitating conditions). Furthermore, the unified theory of acceptance and use of technology was valid in explaining the attitudes of Science and Mathematics teachers toward the integration of ICT in the in their educational practice.

This study aimed to identify the impact of situational leadership on the strategic capabilities of the Kuwait National Petroleum Company, and the case study approach was followed to achieve the objectives of the study. The study population consists of employees in the Kuwait National Petroleum Company, and a convenience sample of 100 employees has been drawn to distribute the study questionnaire to them.

It was found that there is an impact of situational leadership in its dimensions (leadership skills, leadership styles, participation in decision-making, and situational planning) on the strategic capabilities of the Kuwait National Petroleum Company. The study recommends the need to work on establishing an organizational environment that stimulates and supports the strategic capabilities of the company, by paying attention to the factors of situational leadership within the company, and educating the company’s employees about the goals and importance of situational leadership and the consequences thereof through training courses and holding conferences and workshops in order to enhance strategic capabilities.

Experiences of Adolescents Who Are Living with Inflammatory Bowel Disease

Published: February 2021

BACKGROUND: Inflammatory bowel disease (IBD) is an incurable, chronic, gastrointestinal condition characterised by recurrent bouts of debilitating abdominal pain and diarrhoea. There is little information on how adolescents with paediatric IBD (PIBD) face the challenges of living with the disease and their perceptions of their journeys towards adulthood. This paper reports the findings of a qualitative study on these issues in adolescents living with PIBD in South Australia.

METHODS: Potential study participants, aged between 12 and 17 years were selected by a treating clinician from the PIBD clinic of a major referral hospital, to achieve gender balance and some diversity in the PIBD stage and severity. In-depth face-to-face interviews focused on participants’ perceptions about living with IBD during adolescence and for the future. Interviews were recorded, transcribed and analyzed thematically.

RESULTS: Nine adolescents aged 15-17 years consented to participate in the study. Using an overarching theme of ‘the journey’, three major temporal themes were apparent, namely, ‘Reactions at time of diagnosis’, ‘Learning to cope with IBD’ and ‘Acceptance and the future with IBD’.

This study demonstrates that, even with optimum support, the pathways towards adulthood were often turbulent and challenging for these young people due to the unpredictability of painful and/or embarrassing physical symptoms. They nevertheless developed strategies which enabled them to accept and cope with a new ‘normality’ with positivity and determination. More research is warranted to investigate the skills required to navigate this path successfully.
Remittances, Regional Integration, and Balance of Payments Constrained Growth in El Salvador
Authors: Caceres Luis Rene
Published: February 2021

This paper presents a reworking of Thirlwall's model of economic growth restricted by the balance of payments for El Salvador, taking into account its trade flows with the other Central American countries and its remittances. The results indicate that there is a restriction on the economic growth of this country determined by the economic growth of the other countries of the subregion. It is also found that the role of remittances in alleviating external restriction is low. Evidence is presented that this restriction can be overcome by increasing the quality of education. The work concludes by pointing out the urgency for Central American countries to substantially improve the quality of their educational systems, as a means of increasing their economic dynamism.
PROPER APPLICATION OF THE PROVISIONS
ON SUPERVISION AND THE PROBATION OFFICER
IN THE EXECUTIVE PENAL CODE
(ARTICLE 55 § 2ND SENTENCE 2 OF THE E.P.C.)
Authors: Stasiak Krzysztof
Published: February 2021

In the Executive Penal Code (e.p.c.), in two places (art. 55 § 2 sentence 2 e.p.c. and art. 43d § 3 sentence 2 e.p.c.), the phrase "the regulations on supervision and guardianship apply accordingly" is used. It is a type of reference which is quite often used in legislative technique. Thanks to its use, it is possible to avoid repeating in a legal act the content that has already been applied to another situation. This allows the legal act to be more coherent, but sometimes there are problems of interpretation during the application of this standard. This is due to the fact that the rules that we are supposed to apply properly have been laid down for another legal institution and it can be very difficult to apply them to another situation.
This article is devoted to the analysis of art. 55 § 2 sentence 2 e.p.c. It was made on the basis of legal regulations and available literature. Its aim was to try to decode the norm contained herein and determine the manner of its application. In this study, it has been pointed out that the above mentioned article was originally connected with the execution of custody sentenced to the penalty of restriction of liberty. However, due to the removal from the legal system of the possibility of using this type of supervision, at present, art. 55 § 2 sentence 2 e.p.c. should be used for the activities of a court superintendent related to organising and controlling the performance by the sentenced person (sentenced) of obligations imposed in addition to the penalty of restriction of liberty.

Employees of social work centres and nursing homes have to deal with the consequences of the ever-increasing coronavirus pandemic. The problems faced by social workers during the pandemic became the subject of this study. The research aim was to identify the difficulties faced by social workers in their professional work during the coronavirus pandemic which began on 20 March 2020 in Poland. The method of the study was a computer-assisted survey and the tool applied was the electronic questionnaire as well asindividual in-depth interviews . The study concerned three areas: diagnosis of difficulties occurring in the professional work of employees in the area of work organisation; diagnosis of difficulties occurring in the area of work with the client or environment; collecting opinions on possible remote work carried out by social workers in the future. The survey was conducted in late August and early September 2020 and covered 432 respondents. The data gathering was based on purposive sample where the adopted criterion was employment in a social work centre or a specialist institution connected to social work. The most important problems indicated by the respondents were: lack of appropriate tools, place, as well as procedures and instructions for remote work, lack of support of superiors, increase in the scope of administrative and office duties, and strongly limited cooperation with other services and institutions. We also formulated a set of recommendations in the following areas: equipment, work organisation, support in the area of relations with the client, coordination of social services and institutions.
