Published: June 2021

The study was conducted to find out the effect of cooperative learning strategies on students’ skill of interpretation and analysis at the higher secondary level. The research was quantitative. A pre-test post-test control group design was adopted for the study. One female public sector higher secondary school of district Sargodha was the population of the study. 60 students of grade XI were selected as a sample by using a simple random sampling technique. Two groups were formed: experimental and control comprising thirty students each. The experimental group was taught by applying cooperative learning strategies; jigsaw and scripted cooperation, while the conventional method was used to teach the control group. The period of intervention was sixteen weeks and English book I for grade XI was selected as content for intervention. A self-made test was used to assess the skills of interpretation and analysis as pretest and posttest. Data of pretest and posttest were analyzed by applying paired sample t-test. Analysis of the data showed a significant difference between pretest and posttest scores of the experimental group. On the other hand, there was no significant improvement seen in the control group. Teachers were recommended to use cooperative learning strategies to develop the critical thinking skills of the students.
A gender approach to housing loss in Spain: the case of Las Palmas de Gran Canaria
Authors: Domínguez-Mujica Josefina , Parreño-Castellano Juan
Published: June 2021

In pre-pandemic times, Spain was one of the European countries where the economic crisis hit the real estate market hardest, leading to rising mortgage foreclosures and eviction of tenants, as highlighted by many scholars on the financial geography of housing. Its matched social effects reveal the outstanding role of gender, foreign status, and income levels, starting from the hypothesis that the intersection among these categories shows the dimension of inequality in the neoliberal configuration of cities. The aim of this article is to provide this evidence through the study case of Las Palmas de Gran Canaria, using a GIS to implement statistical correlations of these categories on a microurban scale. The created database rests on information contained in judicial archives (women’s foreclosures and evictions) and on ethnicity and income level statistical information. This allows us to go deeper into the factors of exposure to vulnerability, in accordance with an established academic tradition regarding gender, housing and the city.
General medical practitioners in Czechia: development trends and regional differences
Authors: Šídlo Luděk , Bělobrádek Jan , Maláková Kateřina
Published: June 2021

In Czechia general practical medicine represents the bulk of basic primary healthcare both in terms of the number of doctors and the range of services provided. For the healthcare system to function effectively as a whole requires sufficient capacity and the even distribution of providers across the country. As observed throughout Europe, a key risk is the age structure of the general practitioner population, with most of the capacity being provided by older practitioners, which could affect overall primary care access in the future. In Czechia, the general practitioner age structure is skewed, with the proportion of older age groups continually increasing. This article analyses changes in selected indicators of the number, capacity and age structure of general practitioners at the regional level in 2010–2019 and identifies regions where general healthcare access may be at risk. These areas are often rural and, as the specially created municipality typology shows, the pace of change differs along an urban vs rural line.
Mucormycosis: A Black Fungus- Post Covid Complications
Authors: KR Prithiv Kumar
Published: June 2021

Human to human transmitted disease is the game of coronavirus disease (COVID-19) transmission and it had been declared an emergency global pandemic that caused major disastrous in the respiratory system to more than five million people and killing more than half a billion deaths across the globe. Besides lower acute respiratory syndrome, there is damage to the alveolar with severe inflammatory exudation. COVID-19 patients often have lower immunosuppressive CD4+ T and CD8+ T cells and most patients in intensive care units (ICU) need mechanical ventilation, hence longer stay in hospitals. These patients have been discovered to develop fungal co-infections. COVID-19 patients develop what is known as mucormycosis a black fungal infection that is deadly leading to loss of sight and hearing and eventually death. This chapter will focus on mucormycosis, a black fungus caused during post covid complications.
Correlation between Coronavirus Disease 2019 and Heart Failure: A Review
Authors: Haruta Shoji
Published: June 2021

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to the coronavirus disease 2019 (COVID-19) pandemic, which has resulted in devastating conditions worldwide. In addition to affecting the respiratory system, COVID-19 affects other systemic organs, and in particular, cardiovascular failure is related to the worsening of symptoms and death. Among these, cardiac insufficiency seems to be an important prognostic factor.

Methods and Findings: We reviewed the association between COVID-19 and heart failure by searching Google Scholar and PubMed for reports related to COVID-19 and heart failure and selected those qualitatively and quantitatively established. The presence of heart failure may cause increased susceptibility to SARS-CoV-2 due to an abnormal immune response, which may aggravate COVID-19. In addition, myocardial injury, cytokine storm, endothelial dysfunction, blood coagulation abnormality, and hypoxemia due to respiratory injury may lead to worsening heart failure.

Conclusions: Heart failure and COVID-19 are closely related, and their mechanisms are diverse. Multidisciplinary treatment is required to control the progression of cardiac insufficiency, which complicates COVID-19. Further elucidation of the pathology and establishment of efficacious therapy is desirable.

Published: June 2021

The purpose of the study. In experiments on a hind limb ischemia model in rats, the effect of the TrkA-receptor agonist of the NGF 4th loop dimeric dipeptide mimetic compound GK-2 has been studied on microcirculation in ischemic skeletal muscle.

Methods. the Hind limb ischemia was caused in white male mongrel rats by the femoral artery resection. The compound GK-2 was administered intravenously (1 mg/kg/day during 14 days). Microcirculation parameters were recorded using a computer laser analyzer "LAKK-OP2". Registration was carried out simultaneously in the intact and operated limb before the operation, 1 and 14 days after it.

Results. In the conditions of the hind limb ischemia model, it was shown that the compound GK-2 almost completely restored the perfusion index and its variation coefficient in the ischemic muscle to the intact contralateral limb level by the 14th day after surgery.

Conclusion. It can be assumed that the anti-ischemic effect of the compound GK-2 is associated with the restoration of microcirculation as a result of increased neoangiogenesis.
Teaching Sarcasm to Japanese University Students: Pilot Workshop and Plans for Future Study
Authors: Lucian Marisa
Published: June 2021

In the field of L2 pragmatics, the use of humor is researched far less than other areas, with sarcasm taking up an even smaller percentage of those studies. Despite this, the ubiquity of sarcasm in American media and casual conversation leads many L2 learners of English to struggle to fit in and be in on the jokes, which in turn points to the importance of teaching sarcasm to EFL students. In a pilot workshop, this researcher looked into the potential effects of using explicit instruction, paired with samples of American media and gifs, to teach sarcastic play frames endemic to North America. Participant interviews showed promising effects, which has led the researcher to design a study to examine the effects more concisely over time.
第二言語の語用論の分野のうち、ユーモアに関しての研究は他の分野より比較的少ないです。特に皮肉に関しての研究が割合として非常に少ないです。それにもかかわらず、アメリカのメディアや日常会話的な英語では皮肉がよく使われるため、多くの第二言語の学習者は溶け込もうとして冗談を理解しようとするため、英語学習者に皮肉を教えるのは重要だと思われます。筆者は北米のユーモアの枠組みを生徒に教えるため、パイロットワークショップで明示的な指導法と共に、アメリカのメディアや画像を使った指導の影響について調べました。インタビューの結果により、上記の指導法は参加者に良い影響を与えたことが明らかになり、筆者はその影響をより詳細に調べるために研究を行う予定です。

THE MANAGEMENT OF INDONESIAN DOMESTIC WORKERS BASED ON GOVERNMENT PARTICIPATION IN CHINA
Authors: Pudiastuti Elisabeth Tanti , Nugroho Sukmo Hadi
Published: June 2021

Indonesian domestic workers have been an interesting issue for several years. The existence of the workers, in one side, has played significant roles in generating income, reducing poverty, and generating economic development of the sending country. But in another side, they have also created complicated problems. The problems have frequently involved multiple stakeholders including governmental, non-governmental institution, and private sectors. Therefore, this study focuses on explaining Government participation in managing Indonesian domestic workers in China. China was chosen due to the number of the domestic workers. In order to explain the phenomenon, the researchers used qualitative research method. Consequently, the primary data was collected from interview. In addition, documentary analysis was also used in order to support the data. The study showed that there are at least some Government involved in managing Indonesian domestic workers such as National Agency of Placement and Protection of Indonesian Workers, Private Agencies in sending and receiving country, Ministry of Labor, and Ministry of Foreign Affairs. There are three processes of worker placement namely pre-placement, while-placement, and post placement. The private agencies participated practically in almost all of the process including recruitment, providing education and training, and placement the workers. While, other Government participate in providing administrative process such as providing agreement, documents needed, legalizing private agencies, and collecting the data of the labors. However, administrative process was not run properly. It was because the workers and private sectors have to report their conducting activities. This condition gave impact to the lack of control to the activities. This was also exacerbated by the lack of participation from the workers. They don’t have any information about the job and power to get protection. It was because of the existence of the law and lack of education. Therefore, knowledge about job, law, and involved Government was needed to increase participation and protection of the worker.

THE UTILIZATION OF FUEL DIESEL EMULSION AS A RESERVE SOURCE OF DIESEL FUEL FOR INDONESIAN WAR SHIPS
Authors: Rahman Abdul , Kumara Dwi , Kusdiana Wawan , Nugroho Anton
Published: June 2021

By the development of the time, diesel fuel is made from petroleum which is decreasing in number. Besides that, the emissions produced from burning diesel fuel can also cause air pollution. One of the methods used to minimize the use of diesel fuel and air pollution is by using emulsion fuel. therefore, a precautionary measure is required in preparing a reserve fuel source for Indonesian war ships. And one of the options is with emission diesel fuel. From the results of laboratory trials there was an increase in density, viscosity, flash point, cetane and TAN numbers and a decrease in residue, Lower Heating Value and calorific value. The performance test results show an increase in SFOC and thermal efficiency, but the power, torque and BMEP have decreased. So, it can be concluded that the emulsion HSD has decreased performance but can reduce emissions from the combustion process. So, it is hoped that emission diesel fuel can be used as an alternative as well as a solution to the limitations of diesel fuel in the future, so that it can support tni al operations in the future.

OFFENSIVE AND DEFENSIVE CAPABILITY COMPARISION BETWEEN IVER HUITFELDT CLASS AND PKR105 CLASS BASED ON SALVO MODEL
Authors: Bastari Avando , Kusuma Ekaris , Suharyo Okol Sri , Hartoko Priyadi
Published: June 2021

Warship ability owned by Indonesian Navy is expected to have deterrence effect on other countries that want to disturb the sovereignty of Indonesia. Therefore, the right decision is needed to determine which warship should be chosen to carry out the task of guarding Indonesia's territorial waters. The newest warship that has a deterrence effect and is owned by the Indonesian Navy is the KRI PKR105 class. This ship has reliable capabilities both in terms of offensive and defensive because it is equipped with qualified equipment and weapons. Meanwhile, in future plans, the Indonesian Navy is interested in having a Danish-made Iver Huitfeldt class warship which also has a fairly reliable capability. In this paper, we will discuss the calculation of the capabilities of the PKR105 class and Iver Huitfeldt class which are planned to be purchased by the Indonesian Navy based on the Salvo Model. From the calculation, it can be seen that PKR105 class has the same offensive capability as Iver Huitfeldt class but Iver Huitfeldt class has higher defensive caspability than PKR105. This is because the tonnage of Iver Huitfeldt class is greater than PKR105 as one of the staying power parameters for calculating defensive ability. To overcome the shortage of PKR105 defensive capabilities, a $ 21 million CIWS can be added as one of the defensive power parameters in calculating defensive capability considering that there is still a difference in the PKR105 price of $ 285 million with the Iver Huitfeldt class price of $ 325. With this upgrade option then it can be used as one of the considerations in determining the type of ship that can be selected to increase the combat capability of the fleet.

To be able to activate its function properly, it is necessary tochoose the right missile base weapon. The selection of alternative missile weapons over water requires analysisof information and collects important requirements about data from alternative weapons over the air. In additionto alternatives, it is expected that major criteria will be considered in the selection of the Weapons over the air.In making the decision to procure Weapons Over Water, where the conflict cannot be arranged in the form of ahierarchy because it requires interaction and higher level elements to lower level elements. Therefore in thisstudy the Trial Making and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) methodshave the ability to accommodate the interrelations between criteria or alternatives. Based on data processing,the Exocet MM 40 Block 3 has been selected. This missile has several advantages compared to other missiles,including launching at counters and missfire that is very low and has very good durability.Keywords: Missile Selection, DEMATEL, Analytic Network Process
