Authors: Mubarok Faizul , Hamid Abdul , Al Arif Mohammad Nur Rianto
Published: June 2020

Islamic banking financing is carried out into three categories, namely financing based on economic sectors, financing based on contracts, and financing based on types of use. The funding is faced with risks where the customer is unable to pay the loan. This study discusses the forecasting of Islamic banking problem financing in Indonesia using monthly data from 2003 to 2019. Prediction is made using the Autoregressive Conditional Heteroscedasticity-Generalized Autoregressive Conditional Heteroscedasticity (ARCH-GARCH) method. Forecasting from the results of this study shows that non-performing financing tends to decrease in Indonesia. Islamic banking has been able to manage problem financing well. Islamic banking financing should be focused on sectors that have low risk. The results of this study are undoubtedly useful for stakeholders to make policies to improve the quality of the funding.

Published: June 2020

Background: We aimed to compare the efficacy between clopidogrel and ticagrelor in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI) and their effects on IL-6. Methods: A retrospective analysis and collection of 200 ACS patients diagnosed by the Department of Cardiology, Affiliated Hospital of Qingdao University, Qingdao, China in 2016 were performed. Patients were randomly divided into clopidogrel group and ticagrelor group. Data of left ventricular ejection fraction and ACS clinical classification before PCI, PCI treatment, IL-6, platelet aggregation status, maximum platelet aggregation rate (MPAR), P2Y12 response unit (PRU) and adverse reaction of patients were collected. After PCI, patients were followed up for 1 year to compare the ischemia after treatment between clopidogrel group and tigravilol group. Results: MPAR and PRU after PCI of clopidogrel group were significantly higher than those of ticagrelor group (P<0.05). The expression of IL-6 in two groups peaked at 1 day after PCI and then decreased. That of ticagrelor group was consistently lower than that of clopidogrel group (P<0.05). The incidence of ischemic events after treatment in clopidogrel group was significantly higher than that in ticagrelor group (P<0.001). Conclusion: Compared with clopidogrel, tigerrilol had more significant inhibition of platelet aggregation after PCI in ACS patients, and tigerrilol had better effect after interventional treatment in ACS patients. In addition, compared with clopidogrel, tegrel can significantly inhibit the expression of IL-6 in patients with ACS and better alleviate the inflammatory response after PCI.

Authors: KIM Christian , LEE Song Yi , PARK Sam-Hun
Published: June 2020

Background: This study attempted to identify the problem South Korea faces in its development of the medical tourism industry from the perspective of English education. Methods: To assess the preparedness and problems of future Korean nurses in dealing with foreign patients, a questionnaire was conducted in 2017 on 146 freshman and sophomore nursing major students at CHA University in South Korea. Results: Although the nursing major students were highly satisfied with the English instructors, they did not feel that the curriculum prepared them well to deal with foreign patients in the future. They also felt that the teaching methodology employed in the class should be changed to incorporate more medical content into the nursing English program. Conclusion: In order for South Korea to play a bigger role in the medical tourism industry, higher education institutions for medicine need to pay more attention to the English education of their students. More specifically, team-taught English for Specific Purposes (ESP) curricula should be established in order to meet the needs of future medical professionals.
Poverty, Income, and Unemployment as Determinants of Life Expectancy: Empirical Evidence from Panel Data of Thirteen Malaysian States
Authors: TAFRAN Khaled , TUMIN Makmor , OSMAN Ahmad Farid
Published: June 2020

Background: The primary indicator of public health, which all nations aim to prolong, is life expectancy at birth. Uncovering its socioeconomic determinants is key to extending life expectancy. This study examined the determinants of life expectancy in Malaysia. Methods: This observational study employs secondary data from various official sources of 12 states and one federal territory in Malaysia (2002-2014). Panel data of 78 observations (13 cross-sections at six points in time) were used in multivariate, fixed-effect, regressions to estimate the effects of socioeconomic variables on life expectancy at birth for male, female and both-gender. Results: Poverty and income significantly determine female, male, and total life expectancies. Unemployment significantly determines female and total life expectancies, but not male. Income inequality and public spending on health (as a percentage of total health spending) do not significantly determine life expectancy. The coefficients of the multivariate regressions suggest that a 1% reduction in poverty, 1% reduction in unemployment, and around USD 23.20 increase in household monthly income prolong total life expectancy at birth by 17.9, 72.0, and 16.3 d, respectively. The magnitudes of the effects of the socioeconomic variables on life expectancy vary somewhat by gender. Conclusion: Life expectancy in Malaysia is higher than the world average and higher than that in some developing countries in the region. However, it is far lower than the advanced world. Reducing poverty and unemployment and increasing income are three effective channels to enhance longevity.

Background: This study was conducted to evaluate the success rate of male infertility treatment and the factors affecting its outcome. Methods: In a historical cohort study, from Mar 2013 to Mar 2014, 323 couples with male factor were investigated. Couples had treated with IUI or/and ICSI were included randomly. Assisted reproduction technology (ART) outcome (treatment success) was defined as a live birth. Age, duration of infertility, type of infertility, treatment history and clinical examination results were investigated. The logistic regression and survival analysis were applied. Results: The average of men age, duration of infertility and BMI were 33.5, 4.7 (yr) and 26.6 (kg/m2 ) respectively. 87.9% of men have primary infertility and average duration of treatment was 14.1(month). Previous treatment, type of infertility, treatment method, man's BMI, normality of sperm and sperm head were important variable that affecting outcome. The rate of live birth in the first attempt was 29.7%, and 44.9% of the couples succeeded to give live birth after several treatment cycles. Couples who had no previous history of treatment were 8.5 times more successful in live birth. The Cox analysis showed that "BMI of man" and percentage of "Sperm with normal head" are predictors that had a significant effect on live birth. Conclusion: Live birth in the first treatment cycles was influenced by four variables but two other variable were affecting several treatment cycles outcome. The chances of successful treatment were higher with taking into account the length of time and having live birth was determined as 78% for five years of continuous treatment.

Urinary iodine is a good indicator of iodine intake status. Urinary iodine status in at-risk groups is one of the most important indicators of community status. Methods: All 56 universities/medical faculties in Iran should determine and report median urinary iodine and its relative distribution in school children aged 8 to 10 yr, to determine the status of urine output. The sample size in each university/college is 240 students and the cluster sampling method (48 clusters in each area in 2016) and based on probability Measurement. The amount of urinary iodine was measured quantitatively by acid digestion. Results: The mean urinary iodine excretion was estimated at 18.61 μg/dl. The median urinary iodine concentration in 52 universities was sufficient, and the national mean of urinary iodine excretion rate was 19.3 μg/dl. The iodine status was estimated in the optimal range in 65.6% of the students and in only 4.7% in the range of moderate and severe deficits, based on the urinary iodine index. Conclusion: Iodine is sufficient in most parts of the country. The implementation of the country’s national program for the prevention and control of iodine deficiency disorders has made more important the quality control of the collaborative laboratories of this program than before. Moreover, it is absolutely essential to avoid excessive iodine in order to prevent possible side effects.

Authors: Abdollahi Mohammad Bagher , Jafari Mohammad Javad , Panahi Davod , Rahmati Ali Reza
Published: June 2020

Introduction: One of the major factors that affect the employees' health and productivity in industries is the air quality of work environments. One of these pollutants is ammonia gas, which is very important from an economic and environmental points of view. Therefore, this study aimed to investigate the effect of using acidic water compound on the removal efficiency of air ammonia in a spray tower.
Materials and Methods: In this study, airflow was provided by variable ventilation and water pressure through a class electropump. The rate of ammonia removal from the air stream was investigated by a spray tower with changes in water pressure, inlet gas density, and number of nozzles. For this purpose, at different inlet densities, different liquid pressures and different nozzles with water washing liquid with 0.01 mM sulfuric acid were used as the washing liquid.
Results: Increased number of nozzles from one to three had a significant effect on ammonia removal (P-Value = 0.021). Increase of the inlet ammonia gas density from 24.1 to 68 parts per million significantly reduced the efficiency (P-Value = 0.058). Increase of the spray pressure from 9 bar to 12 bar also significantly increased the removal of ammonia gas from the spray tower outlet (P-Value = 0.052).
Conclusion: Increased number of nozzles, increased spray pressure, and decreased density of the ammonia gas inlet gas will increase removal efficiency.

Published: June 2020

This study reports the preparation of superhydrophobic covalently attached poly(dimethysiloxane)(PDMS)/fumed silica composite coatings on glass via spin-coating and subsequent heating. The effect of PDMS molecular weight and fumed silica type (hydrophilic and three different hydrophobic) on the wettability and morphology were studied in detail and the wettability and morphology of the coatings were characterized by contact angle measurements and scanning electron microscopy (SEM). Superhydrophobic coatings which have advancing contact angles of 172-174° and contact angle hysteresis (CAH) as low as 7-8° were obtained using 4% (w/v) PDMS modified hydrophobic fumed silica and all kinds of PDMS. The surfaces which were prepared by 4% (w/v) hydrophilic and dimethylsiloxy modified fumed silica had high advancing contact angles of 163-168° but the CAH on these surfaces were higher than the ones prepared using PDMS modified fumed silica. This can be ascribed to the incompatibility of the hydrophilic and dimethylsiloxy modified fumed silica with the PDMS matrix which was also confirmed with the SEM results.
In situ Crosslinking System of Gelatin with Acrylated β-cyclodextrin Towards the Fabrication of Hydrogels for Sustained Drug Release
Authors: ARSLAN Mehmet
Published: June 2020

Cyclodextrins (CDs) are of interest in fabrication of various polymeric platforms; especially the crosslinked networks that possess unique advantages in biomedical applications. Benefiting from the abilities of CDs to form inclusion complexes with hydrophobic drug molecules, hydrogel-based sustained drug platforms employ CDs as nano-buckets in the network structure. In the current study, we report on the fabrication of gelatin based hydrogels chemically crosslinked with acrylated β-cyclodextrin (β-CD) as sustained drug release platforms. A simple and practical synthesis of crosslinked networks was achieved by Michael addition reaction of gelatin amino functionalities onto acryloyl groups of modified β-CD. Tunable synthesis of hydrogels incorporating different amount of β-CD molecules were maintained by simple adjustment of the reaction stoichiometry between amine and acrylate groups. The resulting hydrogels were characterized by their equilibrium swelling ratios and rheological properties. Thus obtained hydrogels were evaluated in terms of their drug loading capacities and sustained release efficiencies. The results demonstrated that the amount of drug loading and prolonged release is dependent on the amount of β-CD in the gel network. Owing to their in situ gel forming abilities, these hydrogels can be used as injectable formulations for various biomedical applications.
El éxtasis y el proyecto. Notas sobre el fin del mundo
Authors: Grossi Bruno
Published: June 2020

Ante la imposibilidad de imaginar el futuro, la humanidad proyecta en las imágenes del desastre las razones, las ideologías, los miedos y las utopías que laten en cada época. De allí que la impotencia histórica para transformar el mundo ha devenido, en muchos autores, extrañamente literal: la imposibilidad o la renuencia a engendrar. Disposición que no sólo atañe la supervivencia misma de la especie, sino que lleva en sí la rebelión frente a la coerción sistemática del deseo. Este trabajo pretende seguir esas imágenes (presentes en textos filosóficos, literarios y fílmicos) a fin de desentrañar la dicotomía entre el racional proyecto del Estado y el autodisolutorio éxtasis individual.

The Main Provisions of the Article. The most important elements of a system that ensures the smooth functioning of the innovation process are the sources and mechanisms of financing technological innovation. At the present stage of development, such an adequate and effective holistic system in the Russian Federation has not been created. The key conditions for creating a favorable economic environment are: the effective functioning of financing mechanisms, the quality and condition of investment sources, which determine the ability and potential of creating and implementing technological innovations. The digital economy is currently opening up conceptually new sources of funding. The dynamic development of digital solutions and technologies in the financial sector enables organizations to reduce the time spent on searching and making decisions about the source, mechanism and procedures for financing operational and strategic activities. The innovative activity carried out on an ongoing basis allows organizations to dynamically develop, meet business trends, or even create them. As you know, innovation requires serious investment and, as a rule, the more risky the innovation, the greater the profitability it has. In foreign practice of financing innovation, crowdfunding platforms have become widespread. Currently, the United States and individual EU representatives are the undisputed leaders in the development of financial technologies, payment systems, digitalization of financial services. In terms of the penetration of digital technologies in the financial sector (it reaches 85% according to experts), such countries also occupy the first positions. One of the main trends of the financial sector in developed countries is the creation of virtual banks and the Internet banking service. The article analyzes and evaluates the structure of sources of financing technological innovations, carries out a comparative analysis of financing research and development in Russia and developed countries, and considers the possibilities of using digital tools and sources to finance innovation.

The Indonesian National Qualification Framework in higher education requires universities to develop a curriculum that makes students have superior competence with a variety of skills that are in line with the demands of the 21st century, including Critical thinking skills. The main objective of this research is to analyze the practicality of the OR-IPA learning model, which has been developed by design to improve the critical thinking skill of prospective physics teachers on the fundamentals of physics courses. The subject of practical observations was a physics lecturer who used the OR-IPA learning model. The observation sheet of the OR-IPA learning model practicality has been declared valid and reliable by the validators. The data analysis technique uses descriptive qualitative. The results showed that the OR-IPA learning model to improve the critical thinking skill of prospective physics teachers was considered practical (3.69). Lecturers and students can use the OR-IPA learning model without significant obstacles. This research implies that the OR-IPA learning model can be an alternative to improve the critical thinking skill of prospective physics teachers in the fundamentals of physics courses.

The COVID-19 epidemic is an emerging infectious disease of the viral zoonosis type caused by the corona-virus strain SARS-CoV-2, is classified as a human-to-human communicable disease and is currently a pandemic worldwide. In this paper, we propose conceptual mathematical models the epidemic dynamics of four compartments. We have collected data from the Djibouti health ministry. We define the positivity, boundedness of solutions and basic reproduction number. Then, we study local and global stability and bifurcation analysis of equilibrium to examine its epidemiological relevance. Finally, we analyze the fit of the data in comparison with the result of our mathematical results, to validate the model and estimating the important model parameters and prediction about the disease, we consider the real cases of Djibouti from 23th March to 10th June, 2020.

Статья посвящена моделированию процесса вытеснения нефти водой и формирования неустойчивости Саффмана-Тейлора. Задача решается в двумерной постановке. В качестве геометрии рассматривается круговая область с одной нагнетательной и 8 добывающими скважинами, расположенными по контуру вокруг нагнетательной скважины. Для исследования закономерностей вытеснения нефти водой рассчитываются гидростатическое давление, скорость фильтрации нефти и воды, нефтенасыщенность. При графическом анализе в работе рассматривается преимущественно поле нефтенасыщенности. Расчет поля гидростатического давления получается из решения стационарного уравнения пьезопроводности, поле скорости фильтрации нефти и воды рассчитывается из линейного закона фильтрации Дарси, а поле нефтенасыщенности - из решения уравнения адвективного переноса. Двухфазность рассматриваемого в задаче течения выражается тем, что для фазы нефти и фазы воды характерны свои относительные фазовые проницаемости, вычисляемые с использованием модели Брукса-Кори. Уравнения решаются численно с помощью метода конечных объeмов. Для дискретизации расчетной области используется нерегулярная треугольная сетка. В результате моделирования установлено, что вид неустойчивости Саффмана-Тейлора в силу своей случайности сильно зависит от используемой расчетной сетки. После обводнения добывающих скважин происходит стабилизация фронта вытеснения. Неустойчивость усиливается с увеличением отношения динамических вязкостей нефти и воды.

A Greenhouse has a different microclimate compared to the outside field. Climate parameters such as solar radiation and air temperature are important parameters that affect plant growth and productivity. This research aims to understand the relation of climate factors in the inside and outside Greenhouse, the effect of microclimate on evapotranspiration and to predict the amount og evapotranspiration inside the Greenhouse. Microclimate analysis was held in two stages, the firststage was from February 5 to March 21, 2018 and the second stage from March 19 to April 29, 2019 at the Department of Civil and Environmental Engineering, IPB University. Primary data was measured by the Decagon sensor. Solar radiation was collected using the Decagon PYR Pyranometer sensor and air temperature using the Decagon VP-4 sensor. Based on the result, the daily air temperature inside the Greenhouse was higher than that of the outside. The inside solar radiation was lower than that of outside the Greenhouse. The relative humidity fluctuated, and the air pressure was higher inside the Greenhouse. Evapotranspiration inside the Greenhouse was lower than outside and solar radiation was the most determining factor of evapotranspiration.

Dagcoin digital currency is one of the tools of online-based transaction payments that increasingly growing in the global economy. Nowadays The Investors interest to invest digital currency. Indonesia is a law country must establish certain laws related to digital currency that began to spread and used as a means of exchange or means of payment in Indonesia. This study is a normative juridical study that examines the rules relating to the use of money in the sale and purchase transactions and investment in the perspectives of Islamic law and Positive Law in Indonesia. The results of this study found that in Islam the use of digital currency in the purchase transactions and investment is not in accordance with the Shari'ah because it does not fulfill the enquires that exist in transactions using digital currency such as dagcoin. The existence of elements of gharar and maisir is the main reason for this digital money is not legitimate in Islam. As mentioned at Fatwa DSN-MUI Number 28 / DSN-MUI / III / 2002 on the exchange of money. Whereas in view of the positive Law has been described in Act No. 7 of 2011 on money, then digital money cannot be said as money because the conditions set in the law are not in digital money, then Bank Indonesia Regulation Number 18/40 / PBI / 2016 on the payment of electronic transactions is also not met in transactions that exist on the use of digital money dagcoin. So does the electronic transaction information law (ITE). Unclear regulation of the use of digital currency makes some users feel restless.

Indonesia is a pluralistic country because it has a diversity of cultures (culture), ethnicity (ethnicity), race, religion (religious beliefs). To unite the diversity, the Indonesian nation's motto is written on the symbol of the Indonesian state, Bhinneka Tunggal Ika, with different meanings but still one spirit and also poured into the third Pancasila sila with the sound of Indonesian Unity, of course there are things you want revealed from the diversity that is to know the values in terms of Islamic religious education. To realize this desire the authors use a qualitative descriptive approach. The type of research is library research or library research, namely research conducted by collecting some literature from journals or previous research results as a form of comparison with the research that will be conducted.
