This study aimed to investigate and describe the management of developing potential students based on Islamic views. This study used a qualitative method with a case study approach. The subjects of the research were Madrasah supervisors, Madrasah headmasters, and the teachers. The results of the study showed that the development of potential students when referring to the objectives of national education in particular and development, in general, is to create "Total Man" by creating human beings who has complete characteristics, harmonious, and balanced in the development of all aspects of his personality. Humans as a whole are individuals who can reach all relationships with God, with the environment or natural surroundings, with other humans in a constructive social life and with themselves. Management of the development of potential students based on Islamic views stipulates that new education will end when someone dies. Physically, seeking knowledge will end when someone dies, but the process of seeking knowledge continues to an infinite limit.

Authors: Mani Nurfatimah
Published: February 2020

Perusahaan atau pemberi kerja memiliki hak dan tanggungjawab untuk memberikan Jaminan sosial Tenaga Kerja kepada karyawan dan anggota keluarganya, sesuai dengan Undang-Undang No 13 Tahun 2003 tentang Ketenagakerjaan dan Undang-undang No. 24 Tahun 2011 tentang BPJS. Pada prakteknya Perusahaan masih banyak yang tidak membayar Iuran BPJS Ketenagakerjaan secara rutin dan tertib sehingga terjadi penunggakan dan pemblokiran rekening Perusahaan yang berakibat tenaga kerja tidak dapat menerima haknya sesuai dengan program BPJS yang diikutinya. Perusahaan paling sering menggunakan alasan tidak membayar iuran dikarenakan adanya permasalahan keuangan. Tenaga kerja secara otomatis tidak akan bisa melakukan klaim JHT, JKK, Pensiun, JKM yang menjadi hak tenaga kerja dan ahli warisnya bila Perusahaan tidak membayar tunggakannya. Oleh karena itu perlindungan hukum bagi tenaga kerja sangat dibutuhkan untuk menjamin hak – hak mereka dapat diperoleh sesuai aturan yang berlaku. Penelitian ini akan menelaah lebih jauh bagaimana perlindungan hukum bagi tenaga kerja yang bekerja di Perusahaan dimana Perusahaan tersebut tidak membayarkan iuran BPJS Ketenagakerjaan sesuai aturan. Metode yang digunakan adalah penelitian yuridis normative yang mengkaji lebih dalam Undang-undnag dan peraturan pendukungnya terkait dengan perlindungan hukum bagi tenaga kerja. Hasilnya diperoleh bahwa  walaupun telah diterbitkan Undang-undang dan peraturan pendukungnya tidak menjamin hak-hak tenaga kerja terpenuhi dengan pasti,  sehingga perlu upaya penegakan hukum bagi Perusahaan yang melanggar dan dengan sengaja tidak membayarkan iuran BPJS Ketenagakerjaan.

Published: February 2020

Setiap warga negara Indonesia memiliki hak yang sama dalam hal mendapatkan kesehatan, pedidikan dan pekerjaan yang layak. Hal tersebut merupakan amanah dari Undang-Undang Dasar Republik Indonesia yang harus diwujudkan oleh Pemerintah. Untuk itu perlahan namun pasti, Pemerintah telah mensosialisasikan beberapa program yang pro rakyat, salah satunya adalah dengan menghadirkan program Badan Penyelenggara Jaminan Sosial (BPJS). BPJS memiliki 2 program besar yaitu dalam hal kesehatan dan ketenagakerjaan. Untuk pendampingan ini lebih di fokuskan kepada BPJS Ketenagakerjaan. Hal ini karena di beberapa daerah masih banyak dijumpai ketidak pahaman atau bahkan tidak peduli terhadap program BPJS Ketenagakerjaan ini, terutama bagi pengusaha atau si pemberi kerja. Jika hal ini terus terjadi maka hak-hak para pekerja akan terabaikan dan tentu akan merugikan para pekerja itu sendiri. Sehingga dengan adanya pendampingan ini, diharapkan para pengusaha nantinya akan lebih peduli terhadap kesejahteraan dan keselamatan pekerja. Pada pendampingan ini pula, nantinya akan di berikan tutorial terkait bagaimana cara mendaftarkan para pekerja ke BPJS Ketenagakerjaan. Selain itu akan di beri penjelasan pula terkait hak dan kewajiban sebagai anggota dari BPJS Ketenagakerjaan, serta tidak lupa cara mengajukan klaim apabila ada pekerja yang mengalami kecelakaan saat menjalankan pekerjaannya. Pendampingan ini dilakukan di Kediri, dengan sasaran utamanya adalah pekerja tradisonal.

Published: February 2020

Abnormal T cell responses are central to the development of autoimmunity and organ damage in systemic lupus erythematosus. Following stimulation, naïve T cells undergo rapid proliferation, differentiation and cytokine production. Since the initial report, approximately two decades ago, that engagement of CD28 enhances glycolysis but PD-1 and CTLA-4 decrease it, significant information has been generated which has linked metabolic reprogramming with the fate of differentiating T cell in health and autoimmunity. Herein we summarize how defects in mitochondrial dysfunction, oxidative stress, glycolysis, glutaminolysis and lipid metabolism contribute to pro-inflammatory T cell responses in systemic lupus erythematosus and discuss how metabolic defects can be exploited therapeutically.

It has been analyzed impact of forest fire on the air quality using PM10 parameter and visibility during 2000 – 2014 in Palangka Raya, Central Kalimantan province. Palangka Raya is an affected forest fire area with a monsoonal rainfall type which has one peak of the rainy season in January and one peak of the dry season in August. Drought condition has an impact on rising forest fire intensity causes increasing of PM10 concentration and decresing of visibility in July to November moreover when there is an El Niño phenomenon. The result of PM10 analysis shows that the air quality index in Palangka Raya during December - June is in a good  level category and still below the ambient air quality standard with an average concentration of 19 µg/m3. The impact of forest fire on declining air quality due to increasing of PM10 concentration occurred in July – November with an average concentration rising of 129 µg/m3. The El Niño phenomenon rises the PM10 concentration due to increasing of forest fires, but the increasing of PM10 is not comparable to the strength of El Niño, because of combustion condition and and human activities that play a role in forest fires. The worst impact of El Niño occurred in 2002, although the El Niño strength was only moderate, which is a half the time from July to November Palangka Raya covered air quality with dangerous levels with PM10 concentrations of more than µg/m3. A high PM10 concentration environment reduces the visibility significantly, which is visibility in the no fire condition about 8 km, but when the huge forest fire the visibility drops to 0.1 km.

Children with neurodevelopmental disabilities (NDD) suffer poor oral health problems (OHP) leading to adverse health outcomes. We examined the association between NDD and OHP among children in the United States (US) ages 3-17 years using data from the National Survey of Children’s Health (NSCH) 2016-17. The prevalence of OHP was 19.1%. Children with NDD had about 40% greater likelihood of poor oral health compared to their non-NDD counterparts (p <0.0001). Living at or above 200%-300% of the federal poverty level (FPL), private insurance coverage, and living with a least a college educated adult were found to be protective factors against poor oral health among children.

Key words: • Neurodevelopmental disorder • Oral health problems • Children • United States

Maintaining the Sustainable Energy Systems: Turning from Cost to Value
Authors: Pysmenna U. Yе. , Trypolska G. S.
Published: February 2020

The economies of the world are influenced by the rapidly changing global energy policy agenda. Understanding energy trends implications in the long-term perspective is crucial for responsible and informed sustainability-policy making, with respect to transformations required to enhance the security of energy supply, resource efficiency and affordability, as well to as transformations required to minimize energy poverty and mitigate ecological footprint. Nowadays the price (value) competitiveness of technologies and products as their ability to respond to sustainability demands is becoming the appreciable criterion in choosing the pathways of technological growth or economic strategies designing. The transition to energy sustainability is the so-called quiet energy [r]evolution, or the transition towards 100 % renewable energy supply. Using the sociotechnical transition, vulnerability and sustainable development theories for the assessment of the energy safety level, this article aims to contribute to the understanding of cultural, institutional and innovation prerequisites of sustainable energy transitions. Basing on historical examples, it argues that, despite the cultural dimensions, energy resources and energy mix disparity, geographic location and income per capita, the value instead of cost philosophy in choosing energy pathways maintains the sustainable energy transitions. The key findings are the defined prerequisites of energy transitions sustainability; among them there are cultural dimensions, innovations and the speeds of movement along learning curves when adopting new energy technologies as well as energy policy patterns, applied in a country: value versus cost-driven. The Value vs Cost Energy Policy matrix has been developed in order to determine if a country is sufficiently value-driven in its energy policy.
Simulation of Electric Networks Modes Using Steady-State and Heat Balance Equations
Authors: Balametov A. B. , Halilov E. D.
Published: February 2020

In the traditional calculations of the steady-state mode of the electrical network, the dependences of the active resistances of the overhead line wire on the ambient temperature and currents in the branches are not taken into account. However, the temperature is a function of the active power losses, the power losses are a function of the resistance and current, and the resistance is temperature dependent. Therefore, these relations should be related to the traditional equations for stationary regimes. In order to increase the accuracy of steady-state calculations, a temperature correction of the resistance of the branches is required. In this paper, we present a method based on the joint solution of nonlinear equations of the steady-state electric network regime and the thermal balance of the wires of overhead lines. The algorithm and the program of calculation of the steady-state mode of an electric network taking into account dependence of active resistances of a wire of an overhead line on ambient temperature and currents in branches have been developed. The quantitative influence of the load current, wire temperature, wind speed, solar radiation on the active resistance of the wires has been estimated, and the errors in calculating annual variable energy losses have been determined. Numerical experiments were carried out for a 6-node modified version of the IEEE test system and equivalent circuit of 110 kV. The results of the calculations of the steady-state regime on various test circuits showed that the non-account of the temperature dependence of the active resistances might cause errors in power loss for individual loaded lines up to 10 %, and for total losses of the system – up to 30 %. This is unacceptable in simulating the modes of the electric network. The results of simulation of steady-state regimes taking into account the temperature dependence of the resistance of the wires are presented on the example of 6-node and 7-node circuits.

In a market economy, increasing the competitiveness of steel products is an urgent trend in science and practice. Development of production of new pipe steels in terms of pipe-rolling plant open joint-stock company «BSW – management company of holding «Belarusian metallurgical company» casted on continuous casting machine, was complicated by the emergence of low-alloy pipe steel grades of internal defects, which negatively affects the quality of the pipes. Visual evaluation of samples on the inner surface revealed rolled defects significant clusters, close to each other, having a longitudinal orientation. The edges of the defects are tortuous, torn. Defects found on the inner surface of the pipes are characterized as steel melting captivity and swelling. The reason for the formation of internal defects of hot rolled pipes «steel-melting captivity and swelling» was the rolling of defects in the macrostructure of the central zone (central porosity and axial liquation) of a continuously cast workpiece with a diameter of 200 mm.

Key global and Australasian bodies have reported research suggesting the accounting profession is one of the most vulnerable to disruption through automation and changed business models. For universities seeking to improve the employability of graduates and professional bodies seeking to support professional members on a successful lifelong career, the research presented in this paper reconfirmed the need to reappraise the capabilities that would enhance professional practice and lead to sustained careers. This report presents the findings from a validation process across Australia and New Zealand that includes 2,074 responses to a survey conducted by Chartered Accountants Australia and New Zealand. The report confirms 24 capabilities, including six considered essential requirements for every professional seeking to work in accounting, finance, and related work roles. The findings provide evidence that these capabilities, in contrast to recent reports suggesting employment opportunities for accounting graduates are in decline, can create opportunities for sustainable careers. The validation project and survey results provide unexpected insight into the capabilities of different age groups and professionals at different career stages that are considered important. The paper outlines how this research will not only inform continuing professional education for members but also help refine the design of post-graduate curriculum and continuing professional development.

Background: Adults with chronic conditions such as heart disease, diabetes, or lung disease are more likely to develop complications from a number of vaccine-preventable diseases, including influenza and pneumonia. In this study, we use the data from a chronic disease management information system in Shanghai to estimate vaccination coverage and characterize predictors of seasonal influenza and 23-valent pneumococcal polysaccharide vaccine (PPSV23) vaccination among people with chronic disease in Shanghai.Methods: The Shanghai Centers for Disease Control and Prevention have information systems related to chronic disease management, hospital records, and immunizations. Data from individuals with hypertension, diabetes and chronic obstructive pulmonary disease (COPD) were abstracted during July 2017. The main outcome was coverage of pneumococcal and influenza vaccination. Vaccination coverage was calculated across demographic groups. Significance in bivariate associations was assessed through Pearson’s chi-square tests, and in multivariable models through logistic regression models with a forward stepwise method to select variables.Results: In the sample of 2,531,227 individuals ≥15 years, 22.8% were vaccinated for pneumonia from January 2013 to July 2017, and the vaccination coverage of influenza in the 2016/17 influenza season was 0.4%. Vaccination coverage was highest in those 70-79 and lowest in those younger than 60. Compared to urban areas, uptake in rural areas was higher for pneumonia vaccination (OR: 2.43, 95% CI: 2.41, 2.45), but lower for influenza vaccination (OR: 0.55, 95% CI: 0.51, 0.59). Having a greater number of chronic diseases was associated with higher likelihood of pneumonia vaccination (3 vs 1: OR: 1.68, 95% CI: 1.64, 1.71), but this relationship was not statistically significant for influenza vaccination.Conclusions: We found low levels with of pneumococcal vaccination, and extremely low uptake of influenza vaccination among individuals with high risk conditions in Shanghai who should be priority groups targeted for vaccination. Interventions could be designed to target groups with low uptake – like younger adults, and individuals who have not yet retired.

Background
Brucellosis is a zoonotic disease transmitted to humans through contact with infected animals, animal products or consumption of infected dairy products. Brucella infection during pregnancy is of special interest due to association with adverse pregnancy outcomes. This study determined the seroprevalence and factors associated with Brucella infection among pregnant women around the human-wildlife-livestock interface area in Ngorongoro Ecosystem, Northern Tanzania.
Methods
A facility-based cross-sectional study was conducted between May and June 2018 at six health facilities that provide antenatal services. Pregnant women receiving antenatal care were invited to participate. A structured questionnaire was used to collect socio-demographic and obstetric characteristics in addition to behavior and practices related to the occurrence of human brucellosis. The presence of serum immunoglobulin against Brucella was determined using Rose Bengal Plate Test (RBPT). The positive samples were further assayed for the presence of IgG and IgM using Enzyme-Linked Immunosorbent assay. Bivariate analysis was conducted to determine the variables associated with Brucella seropositivity. Multivariable logistic regression analysis was performed to examine the factors independently associations with Brucella seropositivity after adjustment for other explanatory variables.
Results
A total of 313 participants were enrolled in the study. The overall seroprevalence of Brucella infection was 10.9 % (34/313) determined by Rose Bengal plate test. Of 34 positive individuals, 27(79.4%) and 8(23.5%) were positive in the ELISA specific for IgG and IgM Brucella antibodies respectively. Regular contact with manure (AOR 3.16, 95%CI 1.27-7.83) and preference for animal fresh milk (AOR 3.80, 95 % CI 1.23–11.69), raw meat (AOR 2.58, 95 % CI 1.14 – 5.81) and raw animal blood (AOR 2.71, 95 % CI 1.15–6.35) increased the odds of being Brucella seropositive . Contact with the animal placenta were not associated with Brucella seropositivity after adjustment.
Conclusion
This study has found that brucellosis is an important public health problem among pregnant women in areas with interactions of humans; livestock and wildlife. The risk of infection increased with the regular contact with manure and preference of raw foodstuffs like animal blood, meat, and milk. We emphasize the need for interventional strategies to reduce the risk of exposure.

Background There has been data from meta-analysis suggesting that RAMPS is a safe and effective procedure for adenocarcinoma in the body or tail of the pancreas and is oncologically superior to SRPS. However, previous studies on RAMPS were conducted under the open and laparoscopic surgery. Robotic surgery, on the other hand, plays a role in ergonomics and offers several advantages, including less fatigue, tremor filtering, 7° of wrist-like motion, motion scaling, and three-dimensional vision. At present, there is still a lack of clinical studies to observe the safety and clinical efficacy of Robotic RAMPS in the world. Hence,prospective randomized controlled trials (RCTs) comparing Robotic RAMPS and SRPS are required. We begin a RCT trial to compare short-term surgical and oncological outcomes of Robotic RAMPS and SRPS for patients with distal pancreatectomy.Methods This is a randomized, single-center clinical trial. All included adults are patients with primary carcinoma of the distal pancreatectomy. A total of 246 patients will be randomly allocated to Robotic RAMPS or SRPS. The primary endpoints are oncological outcomes(R0 rate, number of Lymph node). Secondary endpoints are the perioperative complications, Perioperative indicators(operative time,blood loss,blood transfusion volume,costs).Discussion To evaluate the surgical and oncological outcomes of Robotic RAMPS, we therefore undertake a prospective RCT. This procedure may become a standard approach to robotic pancreatosplenectomy.

Background Dental plaque biofilms are the causative agents of caries, gingivitis and periodontitis. Both mechanical and chemical strategies are used in routine oral hygiene strategies to reduce plaque build-up. If allowed to mature biofilms can create anoxic microenvironments leading to communities which harbor pathogenic Gram-negative anaerobes. When subjected to high velocity fluid jets and sprays biofilms can be fluidized which disrupts the biofilm structure and allows the more efficient delivery of antimicrobial agents. Methods To investigate how such jets may disrupt anoxic niches in the biofilm, we used planar optodes to measure the dissolved oxygen (DO) concentration at the base of in-vitro biofilms grown from human dental saliva and plaque. These biofilms were subject to “shooting” treatments with a commercial high velocity microspray (HVM) device. Results HVM treatment resulted in removal of much of the biofilm and a concurrent rapid shift from anoxic to oxic conditions at the base of the surrounding biofilm. We also assessed the impact of HVM treatment on the microbial community by tracking 7 target species by qRT-PCR. There was a general reduction in copy numbers of the universal 16S RNA by approximately 95%, and changes of individual species in the target region ranged from approximately 1 to 4 log reductions. Conclusion We concluded that high velocity microsprays removed a sufficient amount of biofilm to disrupt the anoxic region at the biofilm-surface interface.

Background: The health of honeybee colonies is critical for bee products and agricultural production, and colony health is closely associated with the bacteria in the guts of honeybees. Although colony loss in winter is now the primary restriction in beekeeping, the effects of different sugars as winter food on the health of honeybee colonies are not well understood. Therefore, in this study, the influence of different sugar diets on honeybee gut bacteria during overwintering was examined.
Results: The bacterial communities in honeybee midguts and hindguts before winter and after bees were fed honey, sucrose, and high-fructose syrup as winter-food were determined by targeting the V4 region of 16S rDNA using the Illumina MiSeq platform.
The dominant microbiota in honeybee guts were the phyla Proteobacteria (63.17%), Firmicutes (17.61%; Lactobacillus, 15.91%), Actinobacteria (4.06%; Bifidobacterium, 3.34%), and Bacteroidetes (1.72%). The dominant taxa were conserved and not affected by season, type of overwintering sugar, or spatial position in the gut. However, the relative abundance of the dominant taxa was affected by those factors. In the midgut, microbial diversity of the sucrose group was higher than that of the honey and high-fructose syrup groups, but in the hindgut, microbial diversity of the honey and high-fructose groups was higher than that in the sucrose group. Sucrose increased the relative abundance of Actinobacteria (Bifidobacteriales Bifidobacteriaceae) and Alphaproteobacteria (Rhizobiales and Mitochondria) of honeybee midgut, and honey enriched the Bacteroidetes and Gammaproteobacteria (Pasteurellales) in honeybee hindgut. High-fructose syrup increased the relative abundance of Betaproteobacteria (Neisseriales: Neisseriaceae) of the midgut.
Conclusion: The type of sugar used as winter food affected the relative abundance of the dominant bacterial communities in honeybee guts, not the taxa, which could affect the health and safety of honeybee colonies during overwintering. The presence of the supernal Alphaproteobacteria, Bifidobacteriales, and Lactobacillaceae in the gut of honeybees fed sucrose and cheaper than honey both indicate that sucrose is very suitable as the overwintering food for honeybees.
