Published: October 2023

Due to travel restrictions and social distancing, people migrate to online platforms. The Covid-19 pandemic has prompted Malaysians to shop online instead of going to the store daily. This study investigates how Covid-19 affects customer behavior in Malaysia, where some indicators reveal a shift to online shopping during the pandemic. This study employed a survey research design. The researchers tested hypotheses using SPSS. A total of 200 respondents participated in this survey. The data were analyzed with descriptive statistics and inferential statistics. The findings revealed that price, convenience, and service quality could directly affect customer behavioral intention. The researchers also found that online trustworthiness and perceived trust can impact customer satisfaction. Consequently, it is recommended that the retail sector in Malaysia places greater emphasis on enhancing the convenience and service quality in online shopping, continuously elevating service standards to ensure customer satisfaction. Despite the findings showing that price and perceived trust have no significant impact on behavioral intentions in this study, they still have a favorable effect. Therefore, it is advisable for the Malaysian retail industry to enhance its pricing strategies and online security measures.

ANALISIS HARMONISA ELECTRONIC LOAD CONTROL (ELC) PADA PEMBANGKIT LISTRIK TENAGA MIKRO HIDRO (PLTMH)
Authors: Mashar Ali , Sodiq Dja’far
Published: October 2023

Electronic Load Control (ELC) is a common unit used in Micro Hydro Power Plants with synchronous generator to keep network frequency at its nominal. The ELC regulates the power of dummy load as the power flowing to load (consumers) varies. Maintaining frequency is just the same as maintaining the output active power of the plant (generator). If there is change on the load the ELC regulates the power flowing to the ballast (dummy load) by chopping the voltage electronically. Such operation will generate harmonics in the system which can cause problems such as audio noisy and mal function of protection system. This paper evaluates the harmonics content of the ELC in Total Harmonic Distortion (THD) and its influences to the system voltage. Experimental evaluations have been conducted at both laboratory and plant. It gives result that there is un tolerable harmonic content generated by the control unit based on IEEE 519-1992. It gives the same results on the system voltage quality.

Keywords : Micro Hydro Power Plant, Electronic Load Control (ELC), ballast, Total Harmonic Distortion (THD).

ABSTRAK

Electronic Load Control (ELC) adalah suatu unit kontrol yang sudah sangat umum digunakan pada Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) yang menggunakan generator sinkron. Alat ini digunakan untuk menjaga frekuensi jaringan agar tetap pada harga presetnya. ELC mengatur daya dummy load ketika daya yang mengalir ke beban berubah-ubah. Menjaga frekuensi sama halnya dengan menjaga daya keluaran dari PLTMH (generator). Jika ada perubahan pada beban, ELC mengatur daya yang mengalir ke ballast (dummy load) secara elektronik, yaitu dengan melakukan pencacahan gelombang tegangannya. Operasi ini akan membangkitkan harmonisa yang bisa menimbulkan permasalahan seperti terganggunya peralatan audio dan gagalnya sistem proteksi. Paper ini mengevaluasi kandungan harmonisa yang ditimbulkan oleh ELC dalam Total Harmonic Distortion (THD) dan pengaruhnya pada tegangan sistem. Evaluasi eksperimental telah dilakukan baik di laboratorium maupun di PLTMH demikian pula dengan analisis terhadap karakteristik harmonisanya. Ternyata ELC membangkitkan harmonisa melampaui batas yang telah ditetapkan oleh IEEE 519-1992 demikian pula pengaruhnya terhadap kualitas tegangan sistem.

Published: October 2023

Phytotherapy is a therapeutic practice based on plant-based preparations aimed at treating diseases. Professionals from various fields of expertise draw on both traditional and scientific knowledge to formulate various types of plant-based preparations for this purpose. As phytotherapy has transitioned from being considered solely a traditional knowledge-based practice to becoming a highly relevant topic with scientifically recognized merit, it has become an increasingly common practice among healthcare professionals. This is due to its tendency to cause fewer side effects than conventional allopathic medications, leading to increased usage in contemporary societies, justifying the need for this study. Given its historical significance and resurgence in the modern market of plant-based medicines, the objective of this study was to conduct a literature review on phytotherapy. Therefore, this study sought to answer the following question: What are the main current approaches to phytotherapy? To address this question, a literature review was performed based on texts obtained from Google Scholar, primarily focusing on topics such as the history of phytotherapy, types and approaches to phytotherapy, the regulation of herbal medicines in Brazil, and medicinal, nutritional, and integrative phytotherapy, which formed the basis of the sections in this article. As a result, it is evident how rich this therapeutic practice is and how important the use of herbal medicines is, as they can be associated with traditional medicine, primarily because they can cause fewer side effects than conventional allopathic medications.

Introdução: existem relatos de uma manifestação secundária à infecção e atuação viral no organismo: distúrbios do olfato e, consequentemente, do paladar, e que estão presentes antes mesmo da confirmação molecular da infecção causada por SARS-CoV-2. Objetivo: responder quais são os mecanismos de disfunções olfatórias decorrentes da Covid-19, bem como fatores de risco e possíveis intervenções. Metodologia: Trata-se de uma pesquisa descritiva do tipo revisão integrativa da literatura. A pesquisa foi realizada através do acesso online nas bases de dados National Library of Medicine (PubMed MEDLINE), Scientific Electronic Library Online (Scielo), Cochrane Database of Systematic Reviews (CDSR), Google Scholar, Biblioteca Virtual em Saúde (BVS) e EBSCO Information Services, no mês de agosto de 2021. Resultados: Os mecanismos dos distúrbios olfatórios relacionados à infecção por SARS-CoV-2 ainda são desconhecidos, mas é provavelmente o resultado de vários padrões, como edema da mucosa nasal, dano epitelial olfatório e até mesmo envolvimento da região central vias olfativas. Foi demonstrado que a expressão de enzima conversora de angiotensina (ACE2) foi encontrada na camada basal do epitélio escamoso não queratinizante na mucosa nasal e oral e na nasofaringe. Conclusão: Podem ocorrer distúrbios olfativo-gustativos em intensidades variáveis e prévios aos sintomas gerais da Covid-19, devem ser considerados como parte dos sintomas da doença, mesmo em quadros leves. Não há ainda evidências científicas de tratamentos específicos para tais distúrbios na Covid-19, sendo de importância que estudos posteriores consigam, por meio de empirismo clínico, melhor propedêutica para esses casos, principalmente aqueles que manifestam-se como sequela duradoura da infecção por SARS-CoV-2.

Authors: Saputra Herman , Sriwidyani Ni Putu , Paskarani Putu Erika , Hartanto Handoko
Published: October 2023

Introduction: Folliculotropic Mycosis Fungoides (FMF) is the most common case among all variants of Mycosis Fungoides besides Classic Mycosis Fungoides with a worse prognosis than other variants. An understanding of the clinical features and histopathological features of Mycosis Fungoides and its variants is greatly needed in establishing a diagnosis, especially in perspective of Pathology. Methodology: This descriptive study of the case report type and the data obtained from the patient’s medical report. Case Description: A 11 years old girl came with a rash on her right cheek since 3 weeks ago and is increasing in size. On physical examination, there was an erythematous plaque on the right cheek about 2 cm from the nasolabial fold. Microscopic examination showed scattered and infiltrative atypical lymphocyte cells, infiltrative among follicles. The hair follicles showed a degenerated epithelial and cystically dilated epithelium containing follicular mucinosis. Immunohistochemistry shows positive CD3, CD4, CD5, and 10% of Ki67. Conclusion: Although it occurs in 50% of lymphoma cases, cases of Mycosis Fungoides are generally rare. The Folliculotropic Mycosis Fungoides variant is the most common among all the Mycosis Fungoides variants besides Classic Mycosis Fungoides with a worse prognosis than the other variants. It is important to carry out a biopsy examination to assess whether there is an MF lesion, especially Folliculotropic MF in the specimen being examined, moreover if the clinical manifestations in this case vary greatly depending on the stage of the lesion.

Recognizing Traces of Colonialism and Coloniality in a South African Mining Region: Surfacing the Past in Regional, Ethnographic and Well-Being Research
Authors: van Eeden Elize S. , Riukulehto Sulevi
Published: October 2023

Recent discussions on colonialism and coloniality in academic and community contexts have not been fully informed, only understanding the past from a present-day context. This article provides a deeper, more experiential understanding of this culturally complex phenomenon by combining three research methodologies: structured regional research, ethnography informed research and multidisciplinary wellbeing research. The article examines traces of colonialism in the Far West Rand area of South Africa, at a time of expanding mining operations when it was rare for people to think of themselves as ‘colonists’ with a colonial vision. Yet, structured regional research points to a history of immense urbanisation, linked to immigration and strong, almost dominant, features of colonialism. Two other, totally different, research methods have also observed the same phenomenon, adopting a more experiential angle to communities in the Far West Rand. These community experiences relate more closely to a coloniality imagery manifested primarily in ideas and opinions about contemporary service delivery, poverty and land use issues.
Predictors of transition from relapsing‑remitting multiple sclerosis to secondary progressive
Authors: Urban M. A. , Komissarova N. V. , Khazieva I. I. , Shamsutdinova I. I.
Published: October 2023

Currently, the multiple sclerosis (MS) is the second most common cause of disability in young people after injury [1]. Approximately 85 % of patients with MS have a relapsing course, which in a half of cases occurs within 15–20 years, culminating in steady progression with or without activity remaining in the form of an exacerbation or new active foci. Diagnosis of secondary progressive MS (SPMS) is difficult and the diagnosis of SPMS is made retrospectively. Therefore, in our article, we considered options for reliable and objective biomarkers that are natural predictors of conversion and are sources for long-term prediction of diseases.

In this group, the mortality rate was 68.4 %, that is significantly higher than in patients with endogenous phages. K. pneumonia was are the main causative agent of bacteremia and sepsis (12 strains out of 36).Conclusions. Fatal outcomes were more often detected in patients whose endogenous bacteriophages were not detected in the blood. The most serious complications with frequent fatal outcomes were observed in patients with bacteremia caused by K. pneumonia.

Purpose. To conduct an analysis and research aimed at improving the safety of patients during anesthesia by optimizing training in clinical residency in the specialty of anesthesiology and resuscitation. Particular attention was paid to the human factor, as one of the causes of errors and complications in anesthesiology and resuscitation.Material and methods. An additional and more detailed analysis of error factors is carried out using a list of associated error factors. We have developed a special questionnaire for an anonymous survey of clinical residents and anesthesiologists and resuscitators. With its help, we intended to find out what personal qualities an ‘ideal’ anesthesiologist-resuscitator should have.Results. A more in-depth analysis data showed that the most common cause of errors was a lack of practice, in second place there are personal factors, in third place there is a lack of knowledge, and in at last place there are organizational factors. According to the results of an anonymous survey of clinical residents and anesthesiologists, it was established that ‘knowledge’ and ‘skills (abilities)’ are the main factors in ensuring the safety of patients during anesthesia.Conclusions. Questioning should be recognized as an objective, simple and not requiring additional financial costs way to assess a number of social qualities and factors. Training and educating them of the necessary personal qualities of anesthesiologists and resuscitators is one of the most important components of ensuring the safety of anesthesia.

Este estudo analisa os desafios enfrentados por profissionais de saúde durante a pandemia covid-19, no Vale do Paraíba Paulista, interior de São Paulo. Os participantes da pesquisa foram profissionais de saúde de diferentes especialidades que possuíam (anteriormente a pandemia da covid-19) três anos ou mais de prática no contexto hospitalar, atuado diretamente no enfrentamento a pandemia da covid-19 no período de janeiro a dezembro de 2020. Foram entrevistados quinze profissionais de saúde de diferentes especialidades, dentre eles, dois auxiliares de enfermagem, três técnicos de enfermagem, dois enfermeiros, três fisioterapeutas, dois psicólogos e três médicos. Os participantes foram selecionados por meio da técnica bola de neve de recrutamento em cadeia. Foi utilizado um roteiro de entrevista semiestruturada para a coleta de informações. A análise dos dados foi realizada a partir da proposta metodológica de analise dos núcleos de significação, tendo como referência os pressupostos da psicologia sócia histórica. Os resultados apontam para os desafios do combate à pandemia como as técnicas e estratégias utilizadas para conter a doença, a falta de equipamentos, a falta de recursos humanos, rotina exaustiva de limpeza e higienização, jornadas extensas de trabalho, morte, comportamento negacionista da população, o papel da mídia durante a pandemia, a política nacional de enfrentamento ao vírus e o comportamento do presidente. Este estudo aponta para dados que fornecem subsídios para o cuidado com a saúde desses profissionais, além de divulgar a experiência do combate ao vírus da covid-19 e demonstra a necessidade de reconhecimento dessa categoria.
Epigenetic roles in clonal hematopoiesis and aging kidney-related chronic kidney disease
Authors: Ogura Yoshiyasu , Mimura Imari
Published: October 2023

Accumulation of somatic hematopoietic stem cell mutations with aging has been revealed by the recent genome-wide analysis. Clonal expansion, known as clonal hematopoiesis of indeterminate potential (CHIP), is a premalignant condition of hematological cancers. It is defined as the absence of definitive morphological evidence of a hematological neoplasm and occurrence of ≥2% of mutant allele fraction in the peripheral blood. In CHIP, the most frequently mutated genes are epigenetic regulators such as DNMT3A, TET2, and ASXL1. CHIP induces inflammation. CHIP is shown to be associated with not only hematological malignancy but also non-malignant disorders such as atherosclerosis, cardiovascular diseases and chronic liver disease. In addition, recent several large clinical trials have shown that CHIP is also the risk factor for developing chronic kidney disease (CKD). In this review article, we proposed novel findings about CHIP and CHIP related kidney disease based on the recent basic and clinical research. The possible mechanism of the kidney injury in CHIP is supposed to be due to the clonal expansion in both myeloid and lymphoid cell lines. In myeloid cell lines, the mutated macrophages increase the inflammatory cytokine level and induce chronic inflammation. It leads to epigenetic downregulation of kidney and macrophage klotho level. In lymphoid cell lines, CHIP might be related to monoclonal gammopathy of renal significance (MGRS). It describes any B cell or plasma cell clonal disorder that does not fulfill the criteria for cancer yet produces a nephrotoxic monoclonal immunoglobulin that leads to kidney injury or disease. MGRS causes M-protein related nephropathy frequently observed among aged CKD patients. It is important to consider the CHIP-related complications such as hematological malignancy, cardiovascular diseases and metabolic disorders in managing the elderly CKD patients. There are no established therapies for CHIP and CHIP-related CKD yet. However, recent studies have supported the development of effective CHIP therapies, such as blocking the expansion of aberrant HSCs and inhibiting chronic inflammation. In addition, drugs targeting the epigenetic regulation of Klotho in the kidney and macrophages might be therapeutic targets of CHIP in the kidney.
Techno-economic assessment of 5G infrastructure sharing business models in rural areas

How cost-efficient are potential infrastructure sharing business models for the 5G era (and beyond)? This significant question needs to be addressed if we are to deliver universal affordable broadband in line with Target 9.1 of the UN Sustainable Development Goals. Although almost two-thirds of the global population is now connected, many users still lack access to high-speed and reliable broadband connectivity. Indeed, some of the largest connectivity issues are associated with those living in areas of low economic viability. Consequently, this assessment evaluates the cost implications of different infrastructure sharing business models using a techno-economic assessment framework. The results indicate that a rural 5G neutral host network (NHN) strategy helps to reduce total cost between 10 and 50% compared with other sharing strategies. We also find that, compared to a baseline strategy with No Sharing, the net present value of rural 5G sharing strategies can earn between 30 and 90% more profit. The network upgrades to 5G using various sharing strategies are most sensitive to changes in the average revenue per user, the adoption rate, and the amount of existing site infrastructure. For example, the results from this study show that a 20% variation in demand revenue is estimated to increase the net present value of the sharing strategies by 2–5 times compared to the No Sharing strategy. Similarly, a 10% increase in existing infrastructure lowers the net present value by 8–30%. The infrastructure sharing strategies outlined in this study have the potential to enhance network viability while bridging the digital divide in remote and rural locations.
Cognitive reappraisal in mHealth interventions to foster mental health in adults: a systematic review and meta-analysis
Authors: Morello Karolina , Schäfer Sarah K. , Kunzler Angela M. , Priesterroth Lilli-Sophie , Tüscher Oliver , Kubiak Thomas
Published: October 2023

Background

An increasing number of mHealth interventions aim to contribute to mental healthcare of which interventions that foster cognitive reappraisal may be particularly effective.

Objectives

To evaluate the efficacy of mHealth interventions enhancing cognitive reappraisal to improve mental health in adult populations.

Methods

The literature search (four databases) yielded 30 eligible randomized controlled trials (comprising 3,904 participants). We performed a multi-level meta-analysis to examine differences between intervention and comparator conditions at post-intervention assessment. Moderator analyses were conducted for potential moderator variables (e.g., type of comparators).

Results

Most interventions were CBT-based with other training components in addition to cognitive reappraisal. We found preliminary evidence for a small to medium effect favouring mHealth interventions to enhance cognitive reappraisal over comparators, M(SMD) = 0.34, p = .002. When analysing single symptoms, there was evidence for a small to medium effect of mHealth interventions on anxiety and depressive symptoms, but not for psychological distress and well-being. All analyses showed substantial heterogeneity. Moderator analyses revealed evidence for more favourable effects in studies with passive comparators. There was an overall high risk of bias in most of the studies.

Conclusions

We found preliminary evidence for a small to medium effect of mHealth interventions including a cognitive reappraisal component to improve mental health. However, most of the interventions were complex (i.e., reappraisal was provided alongside other components), which prevents us from examining reappraisal-specific effects beyond general mental health promotion in mHealth. Dismantling studies examining the effects of single intervention components are warranted to corroborate these promising results.
