Published: May 2023

This research uses historical method with descriptive-narrative approach and aim to describe the history of the relationship between Batak officers in the Indonesian military during the Revolution to the Liberals in 1945—1959. The results showed that Batak officers were involved in many conflicts, especially in the 1950s, which Ulf Sundhaussen called the Trial and Trial Era. The conflict between the Batak officers involved various events, including the ReRa Hatta incident, the 17 October 1952 incident, Nasution became the Army Chief of Staff for the second time, the Lubis incident, and finally the PRRI rebellion. Differences in educational and religious backgrounds did not really matter to the Batak officers at that time. That means, the Batak officers at that time showed that they prioritized their idealism over their fellow tribesmen. In fact, Batak customs are closely related to the family contained. However, many Batak officers who became leaders in the Army showed that they had a work ethic and morals, in accordance with traditions.Penelitian ini menggunakan metode historis dengan pendekatan deskriptif-naratif yang bertujuan untuk mendeskripsikan sejarah hubungan dan pemikiran para perwira Batak dalam militer Indonesia pada masa Revolusi hingga Liberal tahun 1945—1959. Hasil penelitian menunjukkan bahwa para perwira Batak banyak terlibat konflik, terutama pada tahun 1950-an, yang disebut Ulf Sundhaussen sebagai Era Coba-Coba. Konflik para perwira Batak ini meliputi berbagai peristiwa, antara lain ReRa Hatta, Peristiwa 17 Oktober 1952, Nasution menjadi KSAD kedua kalinya, Peristiwa Lubis, hingga puncaknya pada pemberontakan PRRI. Perbedaan latar belakang pendidikan maupun agama tidak terlalu menjadi masalah bagi para perwira Batak masa itu. Itu artinya, perwira Batak masa itu menunjukkan mengutamakan idealismenya dibandingkan kekerabatan sesama sukunya. Padahal, adat Batak terkenal dengan kekeluargaan yang erat. Bagaimanapun, perwira Batak banyak yang menjadi pemimpin dalam Angkatan Darat menunjukkan bahwa mereka memiliki etos kerja dan moral, sesuai dengan ajaran adatnya.
Discourse analysis on online gender-based humor: Markers of normalization, tolerance, and lens of inequality
Authors: Chavez Jason V. , Prado Rosalina T. Del
Published: May 2023

Language is one of the most powerful means through which sexism and gender discrimination are perpetrated and reproduced (Menegatti and Rubini, 2017). The study examined the contrarian features of gender-based online humor in relation to the mainstreaming of gender and development (GAD). Discourse analysis was used as a method in examining discourse markers of online gender-based humor in terms of defaulting jokes as normal, tolerating sexist jokes, and perceiving that inequality in gender is reality. Fourteen (14) participants who are persons in power or authority, persons based on their educational attainment, persons based on their gender roles, and persons from different generational classifications participated in the study which utilized online gender-based-mapper, one-on-one interviews, and FGD-oriented instruments for the extraction and analysis of the research. After the analysis, it was revealed that the normalization of online gender jokes was prevalent in social media. Normalization proceeds as a way of life in making things light in the conversation and making these conversations intending to have enjoyment and entertainment. For tolerating sexist jokes, it appears that the actors in the online set-up manifest the markers for tolerance through “negligence” which seems to be alarming language production and language distribution to as many social media players.

Dengue is a tropical infectious disease transmitted through the bite of female mosquitoes of the genus Aedes and is of the most common arboviruses in the world. The objective of the present study was to evaluate the frequency of the number of hospitalizations for dengue cases in Brazil between the years 2008 and 2020, comparing the incidences by month, year, states and regions of Brazil. Data on hospitalizations for dengue in the 26 Federative Units of Brazil and the Federal District were used, and these data were obtained through the Departamento de Informática do Sistema Único de Saúde do Brasil (DATASUS) [Department of Data Processing of the Unified Health System in Brazil]. Investigating cases over the years, 2010 recorded the highest number of cases (275.87 ± 20.01) and 2018 the lowest (52.59 ± 5.23). State data differ greatly, with Bahia standing out (596.63 ± 48.41) with the highest number of cases. There is a predominance of hospitalizations during the first semester in Brazilian states and the region of Brazil with the highest number of hospitalizations was the Southeast (281.67 ± 18.72), and the lowest was the South (66.18 ± 9.22). In conclusion, there is no strong trend of increase or decrease of cases over the years; months after the rainy season recorded a higher number of cases; warmer regions had more cases than colder ones
The Changes in the Concept of Society Regulated by Law: In case of civil law
Authors:   The Legal Studies Institute of Chosun University, Yang Chun-Soo
Published: May 2023

Law is often understood as a system of norms regulating society. However, it is not necessarily clear what the concept of society exactly means in this context. This is because society is not only comprehensive in its meaning, but also pluralistic. Because of this, the meaning of society varies depending on what perspective the concept of society is understood. Because of that, the question of ‘society’ or ‘social’ is sometimes raised. In this context, this article examines how the meaning of society regulated by law has changed, especially the meaning of society regulated by civil law as an example. Traditionally, civil law was understood as a private law that regulates society, especially economic system. The society referred to at that time was a civil society centered on citizens. In this civil society, citizens are identified as free and formally equal persons. Accordingly, various differences that actually exist in society are excluded. Accordingly, civil law tried to maximize the freedom of society by assuming society as such a civil society. However, the civil society project premised on the civil law should encounter some limitations in reality. To respond to this limitations, new thinking models and legal concepts have emerged. Social law is one of examples. Unlike civil law, social law actively reveals the differences that exist in society. In addition, changes in the social structure show that the concept of civil society in civil law is no longer sustainable. This article examines what the social concept regulated by modern civil law meant, and how this social concept is changing today. Through this, it is intended to gain useful implications for discussions on social enterprises, social economy and social values that are emphasized in the context of ESG today.

The demand for traditional medicine increased during the pandemic, including instant herbal medicine for children. Children who consume herbal medicine are more interested in colorful products according to the advertised taste, while adult consumers are more interested in herbal compositions that are slightly sweeter (less sugar). This service aims to provide alternative natural dyes and non-sugar fillers for instant herbal products. Accordingly, the service was carried out in two stages. The service program was carried out using the tutorial method and focus group discussions (FGD). Tutorials were carried out online with natural materials as a source of alternative natural dyes and innovations in the use of non-sugar fillers. Group discussions focused on innovations in using non-sugar fillers with low production costs. The results showed that Rosella flowers (Hibiscus sabdariffa L.) are recommended as natural dyes for instant herbal medicine for children for red, yellow, and purple colors, while Suji leaves (Dracaena Angustifolia) for green colors. Additionally, Maltodextrin Fluidized Bed Dryer (FBD) ) is recommended as a non-sugar filler.

This Community Service activity involved farmer groups and the Family Welfare Development Organization (PKK) in Sungai Rasau Village. There is plenty of potential for the production of coconut plantations in the village, but the business of differentiating coconut into cooking oil is of little interest to the community. Low interest is due to relatively limited knowledge and understanding of the economic potential of cooking oil products, especially market uptake. Efforts can be made to increase the added value of cooking oil products. This program aimed to increase the added value of cooking oil products to improve market uptake. Accordingly, the direct learning method was used in this service program, and its activities included training and mentoring. The results of the service program showed that the program that had been implemented generated new enthusiasm for Farmer Groups and PKK. Also, the trademark “MIKOM” was used as branding for coconut cooking oil products from Sungai Rasau Village, accompanied by an attractive offer sentence as a form of online promotion of traditional coconut cooking oil products. Differences in methods and production costs incurred as well as adjustments to the latest costs due to the increase in fuel, became an obstacle for training participants to calculate product selling prices. The participants poorly understood the information technology training because the village lacked sufficient Internet access. Farmer groups carried out the marketing simulation for coconut cooking oil as producers of coconut cooking oil, while the PKK acted as marketing field coordinator.

Ngaran Hamlet, an area in Gilangharjo Village, Pandak District, Bantul Regency, DIY, has a Women Farmers Group (KWT), "Sido Makmur," which is engaged in oyster mushroom cultivation. One of the challenges KWT "Sido Makmur" faces is the fluctuation and instability of oyster mushroom production due to environmental conditions around the mushroom barn, which are not always ideal. To overcome this, the Community Service Team from Universitas Muhammadiyah Yogyakarta (UMY), in collaboration with Singapore Polytechnic (SP), carried out Community Service activities under the Community Partnership (PKM) scheme. This service aims to assist KWT "Sido Makmur" in facing the challenges of oyster mushroom production by designing and implementing Appropriate Technology in the form of a temperature and humidity monitoring system in mushroom barns based on the Internet of Things (IoT). The service team's programs and activities include planning, designing, implementing, testing, and analyzing the IoT technology-based mushroom monitoring system for temperature and humidity. This system allows oyster mushroom farmers in Ngaran Hamlet to monitor the condition of the mushroom coop in real-time and remotely via the IoT platform to increase the productivity of oyster mushrooms optimally. The results of the implementation and testing of the system show that the monitoring tool for temperature and humidity in the IoT-based mushroom barn has been proven to function properly in accordance with the design planning and expectations of oyster mushroom farmers in Ngaran Hamlet.

Authors: Fatma Noorin , Kumar Binod , Jha A. K. , Thakur Indra Shekhar
Published: May 2023

Background: Appendicectomy remains to be one of the most common procedures performed by the general surgeon. Laparoscopic appendicectomy is likely to have less postoperative pain, less use of analgesics, early discharge, decreased wound infection, better cosmetics and also diagnostic and early return to routine work.
Method: This is a comparative study of 50 cases of appendicitis divided equally into two groups 25 in open and 25 in the laparoscopic which were randomly selected and operated in the department of general surgery at PMCH, Patna.
Results: In present study pain score was 2.97±0.7 for open group as compared to 1.56±0.7 in lap group (p<0.05) because of longer incision stretch of muscles and wound infection. Post operative complications like vomiting was lower in laparoscopic group with 12% as compared with 40% in open group (p<0.05) and ileus was lower in lap group with 27±4.6 and for open group 31±5.4 with p<0.05 which were significant. There is significant reduction in incidence of post operative wound infection in lap group 0% as compared to open group 32% (p<0.05). Duration of postoperative hospital stay was significantly low for lap group 2±0.78 as compared to open group 8±0.89. The return to normal activity was low for lap group 14±2.11 days as compared to open group 21.7±3.7days. Duration of surgery for open appendicectomy was 48±19 mins and for lap appendicectomy was 46±15 mins.
Conclusions: Overall laparoscopic appendicectomy is better than open appendectomy in selected patients with acute or recurrent appendicitis.

Authors: Krishna Jadvani  , Siddharth Badola
Published: May 2023

Background: Olfactory dysfunction (OD) has commonly affected covid infected patients. This study is done to detect, analyse and study the recovery pattern of OD in laboratory confirmed COVID-19 infected patients since there is very less data available on OD recovery rate.
Methods: Study design is a prospective cohort type and patients were followed up over 16 months of duration. Data was collected of COVID-19 positive patients from January 2020 to May 2021 who were hospitalized and seen after discharge in out-patient department of tertiary care Santosh medical college and hospital, Ghaziabad (Delhi NCR). In these patients, university of Pennsylvania smell identification test (UPSIT)-40 was used for assessment of OD.
Results: Total number of patients enrolled in the study were 153 of which 15 were lost to follow-up. None of the patients died. Among the 138 hospitalized patients with RTPCR-confirmed COVID-19 infection [mean (SD) age, 38.91 (13.90) years; 70 males (50.7%); 68 females (49.3%)]. This is a prospective cohort study studied over 16 months. At the time of diagnosis of COVID-19, smell sensation was categorised based on UPSIT test as anosmic in 69.6% of the patients, severely amosmic in 9.4%, moderately anosmic in 12.3%, mildly anosmic in 8.7%. After a follow-up for 16 months, full recovery was observed in 125 patients (90.6%).
Conclusions: Prognosis for recovery of olfaction dysfunction in COVID-19 patients was favourable. Individuals with sudden onset and gradual onset OD had higher rate of recovery over one-month follow-up period. Sudden onset OD had higher rate of recovery than gradual onset.

Prospects of improving control over the process of electrochemical machining of the blade airfoil profile using the duplex mode method
Authors: Smirnov G. V. , Shulepov A. P. , Mescheryakov A. V.
Published: May 2023

The paper discusses the features of machining of a compressor blade airfoil. The problem of airfoil deformations under the action of residual stresses that negatively affect the accuracy of the relative position of the airfoil relative to the blade root is discussed. Methods of compensating for the effect of permanent deformations on the accuracy in blade machining and the impossibility of using this approach when the compressor blade is included in the duplex mode technology of electrochemical machining are specified. The analysis of the pattern of electrochemical machining of the blade airfoil with adjustment of the auxiliary technological base developed by the authors and the use of segmented electrodes showed the effectiveness of its use in order to compensate for airfoil deformations. We suggest measuring the interelectrode gaps in the machining chamber after refixturing the base in order to reduce the total machining time. We also suggest using the modernized electrochemical machining scheme when designing a CNC machine for the machining of a blade airfoil.
Survey of the flight efficiency of a long-haul aircraft under uncertainty of tasks
Authors: Markiewicz P.
Published: May 2023

The article considers the problem of optimizing a long-haul aircraft flight under uncertainty of objectives and tasks. Based on the analysis of the well-known flight mode selection criterion, two main objectives of the flight were identified minimizing fuel consumption and flight endurance. The study of this criterion based on a multi-purpose approach made it possible to develop an analytical model of the performance indicator containing two objective functions and a weight coefficient as a measure of comparative importance between the identified objectives. It is shown that the weight coefficient in the tasks of flight efficiency research is a measure of the uncertainty of the tasks. Consideration of the weight coefficient role in the optimization problem objective function made it possible to develop operational and trajectory methods for selecting flight modes. In the developed statement of the problem, the problems of cruise flight optimization and climb and descent modes are considered. The paper introduces the concept of the optimal cruise range as a vertical separation criterion, which allows you to rationally design the flight path at different flight levels under the uncertainty of tasks. The procedure for researching the efficiency and optimization of flight has been conducted and demonstrated by the method of mathematical modeling. The results of optimizing the flight mode are compared with the typical flight modes recommended by the flight manual. The introduced methods of flight efficiency investigation can be helpful in developing recommendations of long-haul aircraft operation. The methods and principles of a multi-purpose approach, operations research and decision theory were used in the paper. The long-haul aircraft IL-96-300 was selected as the object of research.

During the process of designing new devices for the high-speed metallization process, there appears the necessity to define the stable operation range and search for the optimum values of the operation mode and design parameters. This paper describes a process of optimization of a device made for depositing low-melting metal coatings, based on the rocket chamber operation principle. The paper presents an analysis of the objective function surface response metallizer operation performance. On the basis of this analysis the optimal values of fuel mass flow rate and excess oxidant ratio were determined. The choice of fuel and oxidizer throttling orifice cross-section areas was substantiated, the value of the throat cross-section for the metallizer flow-path was found. The expected performance of the designed device was also determined.

The features of a nonlinear model of the indenter-coating tribosystem of a tribometer are considered. It is shown that with an increase in the amplitude of harmonic perturbation, the dynamic system goes through the stage of doubling the cycle and passes into the regime of deterministic chaos. At the exit from chaos, it is possible to establish various synergistic regimes that stably retain their parameters even with a multiple decrease in the amplitude of the disturbance. A block diagram of the implementation of the evolutionary model is presented. As a result of the formation of equilibrium roughness, the motion of the system is a strange attractor. To substantiate the randomness of the strange attractor, an analysis of the amplitude-frequency characteristic of the ideal regenerative delay element with a gain factor less than unity, was carried out. The physical meaning of the strange attractor is that in a cyclic mode, a nonlinear dynamic system whose cycle time exceeds the period of natural oscillations by more than two orders of magnitude cannot come to the beginning of a new cycle with exactly the same parameters as to the beginning of the current cycle.

Numerical modeling for the purpose of receiving the temperature field of cooled rotor blades and its improvement is an integral process of modern design of gas turbine engines since the issue of cooling at gas temperature at the combustion chamber outlet over 1800-2000 K is becoming one of the key ones. To ensure the specified parameters of turbine operation during its design, it is necessary to obtain reliable calculation data. The article presents an algorithm for forming a calculation model to determine the thermal state of the working blade of a high-temperature high-pressure gas turbine in the Ansys program. The process of preparation of geometric and grid models is described, the boundary conditions used to set up the project in Ansys CFX Pre are given. A method for determining the cooling efficiency factor using Ansys CFX Post is also presented. The distributions of the temperature field and the coefficient of cooling efficiency over the surfaces of the blade to be cooled are obtained. Integral values of the coefficient of cooling efficiency for the designed blade at various cooling air flow rates were compared with statistical data. On the basis of the comparison a conclusion was made that the working blade considered in the work corresponds to the modern level of cooling efficiency.

Objectives: This study aimed to explore the quality of life (QoL) of Omani family caregivers (FCs) of patients with traumatic brain injury (TBI). After acute care, the burden of caring for patients with TBI is mainly shouldered by FCs. Methods: This cross-sectional study was conducted at Khoula Hospital, Muscat, Oman. Patient data were collected at the time of discharge and 8 weeks post-discharge between April 2019 and December 2021. The SF-12 General Health Survey and Preparedness for Caregiving scale were used to measure the caregivers’ QoL and preparedness, respectively. The Disability Rating and TBI Symptom scales were used to measure the patients’ disability and symptoms, respectively. Results: A total of 36 FCs and patients with TBI were recruited. Most caregivers were the parent (41.7%) or child (27.8%) of the patient with TBI. Overall, the caregivers had good physical QoL (PQoL) and mental health QoL (MHQoL) but low caregiving preparedness at the time of discharge. At 8 weeks post-discharge, there were significant improvements in caregiving preparedness (P <0.01) and patient disability (P <0.05) but a depreciation in caregivers’ MHQoL (P <0.05), with no change in their PQoL. The caregiver’s employment status and the severity of the patient’s sleep and mood problems were modifiable predictors of the caregivers’ PQoL. Caregiver’s preparedness, the patient’s inability to live independently, and the severity of the patient’s mood and behavioural problems were predictors of caregivers’ MHQoL. Conclusion: Caring for patients with TBI negatively impacts the QoL of Omani FCs; this correlates with the physical, emotional, and mental health symptoms of the patient.

The aim of this study was to examine the protective role of various lipids (olive and soya oil) and vitamin (E and C) against the toxicity of thermally oxidized ghee in rabbits. Vanaspati ghee was thermally oxidized on a hot plate at 100°C for ten consecutive hours, and the oxidized ghee was stored in a refrigerator at –20°C until administration. Thirty male rabbits were purchased as experimental animals at a local market and were divided into ten corresponding groups of three based on their body weight. The blood samples of 5 ml were collected on day 0, 7, and 14 of the experiment for the analysis of hematological and biochemical serum parameters. We observed that oxidized ghee significantly elevated ALT level by affecting liver hepatocytes. Furthermore, vitamin E rapidly decreased the ALT levels compared to vitamin C and other oils. The oxidized ghee caused a significant increase in cholesterol compared to the other groups. Vitamin E and C showed the best antioxidant activity and decreased cholesterol levels to normal. Histopathological examinations of the normal rabbits’ liver sections revealed no significant histological abnormality. The liver of the rabbits fed with oxidized ghee had an intact lobular architecture but the portal tracts showed inflammation and mild fibrosis, the bile ducts showed proliferation, and the hepatocytes showed feathery degeneration. In the liver sections from the groups fed with oxidized ghee and different doses of olive oil inflammation in portal tracts and large vacuoles in the hepatocytes were observed. The group fed with oxidized ghee and vitamin E had intact lobular architecture with no significant histological abnormality in portal tracts but fatty changes were present in the hepatocytes. These findings support the antioxidant activity of vitamins C & E as they reduced liver infection caused by oxidized ghee. It was concluded that oxidized ghee was highly toxic and not safe for consumption. The present study indicated that soya bean oil and vitamin E were more effective in protecting against the toxicity of thermally oxidized ghee than olive oil and vitamin C.

As vilas rurais na Amazônia paraense se configuram como escala de análise geográfica, por apresentarem uma natureza humana, manifestada nas suas formas conteúdos, que lhes confere o caráter geográfico, sendo possível a categorização e conceituação das mesmas. O objetivo deste trabalho é compreender as vilas rurais conceitualmente a partir do olhar geográfico, bem como entender a organização espacial destas formas/conteúdos a partir das ações dos diferentes sujeitos sociais que agem nestes espaços apropriando-se e ao mesmo tempo construindo seus espaços de vivência e produção na Amazônia paraense. Para tanto, a teoria de produção social do espaço foi o referencial teórico que norteou a compreensão dos espaços dos camponeses, produtores, coletores e pescadores em questão. As informações utilizadas neste trabalho foram coletadas durante a realização de pesquisas de campo nas vilas de pescadores de Céu e Cajuuna, localizadas no município de Soure, na Ilha do Marajó e na vila de Agricultores e extrativistas de Santana do Urucuri, localizada no município de São Miguel do Guamá, ambas no estado do Pará. ABSTRACTThe rural villages in the Amazon Pará stand as geographic scale of analysis, because it has a human nature, manifested in its form and content, which gives them the geographical character, being possible a conceptualization and categorization of them. The objective of this work is to understand the rural villages conceptually from the look geographic as well as understand the spatial organization of these (forms and contents) from the actions of different social subjects who act appropriating these spaces while building their spaces of living and production in the Amazon state of Pará. Therefore, the theory of social production of space was the theoretical framework that guided the understanding of spaces of peasants, fishermen and gatherers in question. The information used in this paper were obtained while conducting field research in the fishing villages of Heaven and Cajuuna, located in the city of Soure, on Marajó Island and the village of farmers and gatherers of Santana's Urucuri, located in the municipality of São Miguel Guamá, both in the state of Pará.
