During the COVID-19 Pandemic, differentiating tropical infectious diseases and COVID-19 can be challenging due to overlapping clinical presentations. Fever and nonspecific symptoms in early COVID-19 may be challenging to distinguish from dengue hemorrhagic fever (DHF) and malaria because respiratory signs may be absent or manifest later in the disease course. This literature review analyzes the determinant factors in managing DHF during the COVID-19 Pandemic. This paper was a systematic literature review of national and international journals in the Google Scholar and PubMed databases from 2019 to 2022. We used the PICOS framework to find articles. The Indonesian and English keywords were the speed of health service, dengue hemorrhagic fever, and COVID-19. There were two included studies in this systematic review. The results showed that during the Covid-19 Pandemic and the dengue epidemic, a triage strategy was crucial to detect Covid-19 that could potentially be misdiagnosed as DHF. In addition, the first delay in seeking care treatment for dengue infection was due to financial constraints and previous dengue infection. Moreover, the second delay was because of the availability of transportation, traffic density, and residency location. Furthermore, the third delay was because of the hospital's capacity. Thus, the determinant factors of managing Dengue Hemorrhagic Fever during the COVID-19 Pandemic were the similarity of the signs and symptoms of dengue fever with Covid-19, financial aspects, transportation factors, the hospital distance, and hospital capacity.

The Nias tribe has a unique view of death reflected in its beliefs and traditions. It reflects a blend of Christian elements with local beliefs rich in myths, rituals, and symbolism. Local beliefs are reflected in traditional ceremonies rich in symbols and meanings. But it has slowly adapted to the changing times. It is undeniable that the people of Nias are facing significant transformations due to globalization and modernization. These changes not only affect the way of life economically and socially but also change the understanding and management of corpse. This study uses literature as a guideline in compiling this article. To obtain data, use a qualitative field or ethnographic approach to the social and culture of the Nias tribe. The results indicate that the meaning of death for the Nias tribe has changed along with the interaction with the influence of globalization and modernization. The tradition of death, rich in spiritual and social values, remains a strong foothold in maintaining its cultural identity, despite its adaptation to contemporary dynamics

Abstract Pre-extraction of alginate from brown algae with acidic solvents requires a lot of reactants and water that produce a lot of solvent wastes. This study aimed to optimize the use of acidic solvents by using solvents repeatedly and to determine the effect on alginate quality, water consumption and reactant, and acid solvent waste. Repeated use of solvents on pre-extraction stage was carried out with variations of 0, 1, 2, 3, and 4 times. A Completely Randomized Design (CRD) with three replications was used to determine the effect of repeated use of solvents on the alginate quality. Parameters observed were yield, viscosity, molecular weight of alginate, water consumption, HCl requirement, and the amount of acid solvents waste. The result showed that the repeated use of solvents in the pre-extraction stage produced alginate with an average yield of 26.7%. Repeated use of solvents of 0 to 2 times produced medium quality of alginate with a viscosity of 270.9-360.0 mPa.s and alginate molecular weight of 122,04-175,44 kDa. Pre-extraction of macroalgae by repeated use of solvents can reduce water consumption 22,2%, HCl 66,7%, and waste solvents 66,7%. Pre-extraction of macroalgae by repeated use of acid solvents was potential for efficiency, and further research is needed for a larger scale extraction process.

Elder abuse has continued to be a serious concern to many stakeholders in the world and Nigeria as reported by researchers, as well as various media platforms. It is from this fact that this present study examined the role of social support and socio demographic factors on elder abuse in Ile-Ife Osun state, Nigeria. Theory of social exchange provided the theoretical framework while a descriptive survey was adopted. Three hundred and ninety-two (392) respondents (Males = 192, Females = 200, M = 70.77, S.D. = 6.33) were selected using a purposive sampling technique. Data were collected using a structured questionnaire comprising demographics variables, elder abuse scale (α = .65), and social support scale (α = .94). Data were analysed using T-test for independence measure and analysis of variance (ANOVA). T-test for independent statistics revealed that social support differentiated the experienced elder abuse t(390) = -3.33; p < .001). There were some gender differences in elder abuse (t(390) = 2.20; p = .028). There was no significant relationship between socioeconomic status and elder abuse (F(3, 389) = 1.46; p = .225). The study concluded that social support and gender played a vital role with elder abuse in Osun state. The study, therefore, recommended that government should provide appropriate social support such as prompt payment of pension and gratuity, provision of feeding, good, as well as living arrangements with special attention on elderly men

Through the case studies, Ahok and Meliana, this research aims to explain how the religious minority try to obtain protection to fulfill human rights when faced with religious majority pressure from the majority group. Normative research will answer the problem by analyzing the process of prosecution, the adjudication, and the punishment for Ahok & Meliana and the demonstration both outside the court and in the trial process demanding severe punishment for the accused of religious blasphemy. The result shows that even though it is difficult to prove directly, the mobilization of the masses in the judicial process can affect judges' independence to provide protection and justice for religious minority. The case of Ahok and Meliana shows how difficult it is for minority religious groups to seek protection against pressure from the majority religious groups because the State and Judges cannot prevent and take firm action against mass pressure from the majority religious groups against minority religious groups. The case such as Ahok and Meliana will occur as long as blasphemy's criminalization is still in effect. If the principle of non-discrimination or commutative justice is applied, and not the principle of protection based on 'partiality for the vulnerable,' the protection for religious minority groups will not be realized fully.

The lungs are one of the important and vital organs in the body that function as a respiratory system process. One way to detect lung disease is to do an X-rays test. Chest X-ray is a radiographic projection to detect abnormalities in lung organ by using x-ray radiation. In the process of diagnosing, doctors see the condition of the results of Chest X-rays in the form of a thorax image (chest) to know the patient has an abnormal or normal lung. However, doctors' diagnosis of chest X-rays results-based abnormalities is likely to differ depending on the doctor's abilities and experience. This problem is expected to be solved by segmenting the lung image to help make the diagnosis appropriately. The purpose of this study is to conduct an analysis that can differentiate abnormal and normal lungs. The process of recognition of these patterns consists of the pre-processing stage of image segmentation by using morphology and then proceed to grouping by using fuzzy c-means method to express the pattern of the already segmented image. This research produces normal and abnormal lung images that can be identified with an accuracy of 80%.

Triple cycle power plant with methane as a fuel has been analyzed on the basis of second law of thermodynamics.In this model, ideal Brayton cycle is selected as a topping cycle as it gives higher efficiency at lower pressure ratio comparedintercooler and reheat cycle. In trilple cycle the bottoming cycles are steam Rankine and organic Rankine cycle. Ammoniahas suitable working properties like critical temperature, boiling temperature, etc. Steam cycle consists of a deaerator andreheater. The bottoming ammonia cycle is a ideal Rankine cycle. Single pressure heat recovery steam and ammoniagenerators are selected for simplification of the analysis. The effects of pressure ratio and maximum temperature which aretaken as important parameters regarding the triple cycle are discussed on performance and exergetic losses. On the otherhand, the efficiency of the triple cycle can be raised, especially in the application of recovering low enthalpy content wasteheat. Therefore, by properly combining with a steam Rankine cycle, the ammonia Rankine cycle is expected to efficientlyutilize residual yet available energy to an optimal extent. The arrangement of multiple cycles is compared with combinedcycle having the same sink conditions. The parallel type of arrangement of bottoming cycle is selected due to increasedperformance.
