That the learning outcomes is an overview of the progress or development of students from the first to follow the educational program until the time they ended the educational program which he passes. So the study results can be seen after learners gain experience learning and behavioral changes. So with a change in the student after a learning experience and that's called learning outcomes. Someone students who have high motivation to learn, have the drive or desire to learn a subject, students who have the desire and drive to learn a subject guided by their needs. One needs are close to success in learning a subject is need for achievement. That students who have high motivation to learn, will be marked with a bold desire to compete and receive feedback and encouragement to always be responsible and goal attainment. That students who have the drive to take responsibility and achievement of learning objectives, makes the learners to always be disciplined and focused in learning a subject. Therefore, students who have high motivation to learn, will get better learning outcomes compared to students with low learning motivation. Thus, if in improving learning outcomes of a subject, the need for efforts to increase student motivation. Motivation is realized in the form of action, is one factor that can be used to predict the progress of learning.

STRUKTUR ATOM BERDASARKAN ILMU KIMIA DAN PERSPEKTIF AL-QURAN
Authors: Sabarni Sabarni
Published: July 2019

The atomic structure is one of the chemical metrics studied in high schools and universities. The concept of atomic structure in learning chemistry in schools and universities is usually not associated with religion, especially the Qur'an, so as if learning atomic structure is a separate science and has no connection with the Qur'an. To show that the Qur'an is a guideline for humanity, including examining the natural sciences including chemistry, the authors want to examine the concept of atomic structure based on chemistry and the perspective of the Qur'an which aims to determine the concept of the development of atomic models, particles basic and electron configurations based on chemistry and the Qur'anic perspective. The data collection technique used in this study is literature (Library Research), namely studying the Qur’an  and studying reading books, journals, dictates, dictionaries, and scientific works. From this study shows that the Qur'an has been proven to explain the concept of atomic structure first and in the Qur'an there is the concept of atomic structure which is in line with the chemical concept proposed by chemists.

Latar Belakang. Stunting merupakan salah satu masalah gizi  serius di beberapa negara di dunia, khususnya negara-negara berkembang termasuk Indonesia. Faktor risiko stunting antara lain tinggi badan ibu, penyakit infeksi dan Berat Bayi Lahir Rendah (BBLR) serta faktor lain seperti konsumsi goitrogenik, kadar iodium garam, dan kadar iodium urin. Iodium merupakan mikronutrien penting untuk pertumbuhan dan perkembangan normal. Prevalensi stunting yang tinggi dan status iodium yang tidak diketahui menjadi perhatian penting untuk mengetahui faktor risiko stunting di daerah endemik GAKI. Tujuan. Penelitian ini bertujuan mengetahui faktor risiko stunting di daerah endemik GAKI. Metode. Penelitian ini merupakan penelitian observasional analitik dengan desain penelitian case control. Sampel penelitian adalah siswa sekolah dasar berusia 10-12 tahun  sebanyak 106 orang. Analisis hasil penelitian secara bivariat menggunakan chi square, dan analisis multivariat menggunakan regresi logistik. Hasil. Rata-rata tinggi badan menurut umur (TB/U) anak stunting dan tidak stunting adalah 138,8 cm. Sedangkan rata-rata tinggi badan ibu adalah 148,3 cm yang artinya lebih tinggi dari cut off 145 cm sebagai standar seorang ibu dikatakan pendek/stunting. Analisis bivariat tinggi badan ibu (OR:3,69, CI:1,32-10,32) dan riwayat penyakit infeksi (OR:11.02, CI:2.38-50,90) merupakan faktor risiko stunting (p<0,05). BBLR bukan merupakan faktor risiko stunting. Hasil analisis multivariate menunjukkan tinggi badan ibu dan riwayat penyakit infeksi merupakan faktor risiko yang dapat memprediksi kejadian stunting sebesar 15 persen, sedangkan 85 persen disebabkan oleh faktor lain yang tidak diamati dalam penelitian ini. Kesimpulan. Peluang ditemukan anak stunting dari ibu yang pendek (<145 cm) dan riwayat penyakit infeksi (ISPA dan diare) saat balita lebih tinggi dibandingkan dari ibu yang memiliki tinggi badan normal (>145 cm) dan tanpa paparan penyakit ISPA dan diare saat balita di daerah endemik GAKI.

Babysimulator som pædagogisk styringsteknik – om magt og den frie vilje i sociale indsatser for marginaliserede unge
Authors: Søgaard Vivi Friis
Published: July 2019

Artiklen bygger på et kvalitativt studie af babysimulatorforløb i Danmark og belyser, hvordan de fagprofessionelle forsøger at balancere mellem idealet om borgerens frie vilje og den magt, som uvilkårligt ligger i skulle prøve at påvirke marginaliserede borgere til at træffe bestemte valg om forældreskab. Artiklen tydeliggør også, hvordan de fagprofessionelle i deres ageren ikke blot er styret af det socialpædagogiske felts idéer om det rigtige forældreskab, men også forholder sig kritisk og refleksiv til egen praksis. I dette komplekse arbejde bliver babysimulatoren et kraftfuldt styringsredskab, der gennem simuleret rollespil og »objektive« vidensdata leder deltagerne til (frivilligt) at træffe ansvarsfulde valg om et fremtidigt forældreskab, hvorfor en mere brutal og direkte magtanvendelse kan undgås. ENGELSK ABSTRACT Vivi Friis Søgaard: The baby simulator as a pedagogical guidance technique. On power and free will in social programs with marginalized youth Social robots such as the baby simulator are used by professionals to guide, monitor and regulate marginalized people in becoming competent parents. This article is based on a qualitative study of baby simulator programs in Denmark, and illustrates how professionals try to balance the ideal of the citizen’s free will with the power necessary to influence marginalized citizens in making »the right« decision. The article shows how control techniques like role-play, the use of electronic data, narratives and dream scenarios become new ways of guiding the participants to (voluntarily) make responsible choices about their future parenthood. In addition, the article focuses on how professionals reflect about their use of the baby simulator as a tool of power, and if it is ethically appropriate to let pregnant women participate in the program, since participation might lead these women to choose abortion.

His Master’s Voice? Conceptualizing the Relationship Between Business and the World Economic Forum
Authors: Garsten Christina , Sörbom Adrienne
Published: July 2019

Commonly, the relationship between corporations and non-for profit organizations, such as foundations, think tanks and private research institutes, is analyzed in terms suggesting that when acting as funders corporations set the frames for the non-for profit organization who, in turn, not only mimics but also serves as to broadcast the views of its funder. Drawing on the case of the Swizz based foundation/think tank World Economic Forum and its corporate funders we scrutinize this relationship. We show that as an organization interested in global policy making it is of vital importance for the Forum to construct its own agency, not merely giving voice to its funder’s views, and that it will do so drawing on the resources that the funders provide. Moreover, we submit that as organizations all partaking actors will endeavor to construct their own agency, oftentimes by drawing on the resources of others. In so doing, actors may have both overlapping and divergent interests. Evoking the Lévi-Strauss concept of the bricoleur, we analyze how the various and multifaceted priorities of corporations will not only be filtered by the Form, but it will also make use of the resources at hand for organizing forth own policy messages. The result is a complex and dynamic web of actors and voices.

Na Graduação em Artes Visuais da UFPE, com o objetivo de formação de professoras e professores, nós, professoras do curso, ministramos disciplinas para que esses/essas estudantes vão aos espaços educativos sendo esses formais: as escolas; ou não-formais: museus, galerias, ONGs, hospitais, entre outros, com a consciência de que somos um grupo cultural colonizado, especificamente em relação às artes visuais. E precisamos estudar, pesquisar e compreender um ensino/aprendizagem contemporâneo, democrático e inclusivo. Para isso, fundamentadas em teorias feministas, fazemos escolhas de trabalhos artísticos em que contemplem as mulheres, indígenas, pretas, pessoas com deficiências e de grupos LGBT. Discutir as teorias de autoras mulheres que trazem à luz os trabalhos artísticos dessas, que por muito tempo foram invisibilizadas por historiadores homens, também é outro ponto fundamental nessa perspectiva de Arte/Educação. Com a arte, discutimos questões como a misoginia, homofobia e preconceitos outros que excluem as pessoas da sociedade e da história da arte. Levando essa temática para a sala de aula, fomentamos um movimento circular, no qual as artistas e trabalhos de arte são estudados, levando as/os professores/as em formação a produzirem/pesquisarem arte; a partir dessa produção/pesquisa/reflexão em arte proporcionar à  a sociedade em seus estágios obrigatórios e não obrigatórios, em pesquisas de PIBIC, PIBITI, PIBID, o objetivo de transformar e buscar uma sociedade mais justa, democrática, inclusiva e decolonializada. Para exemplificar essa ciclicidade, trago três estudantes e pesquisadoras do PIBIC apresentando suas produções artísticas.
Los derechos humanos para las personas LGBT y sus limitantes frente al modelo de la ciudadanía normativa
Authors: López Sánchez Ericka
Published: July 2019

Los derechos humanos se implementan en el marco de los Estados democráticos, como un dispositivo potente que fortalece la calidad de las democracias, se posicionan como un discurso de verdad que resuelve las deficiencias de los Estados-nación. No obstante, a estos últimos, se eximen muchas veces de sus responsabilidades cotidianas; así como de una autoreflexión sobre el modelo normativo de ciudadanía generado por la democracia liberal que propicia, por su propia lógica, exclusiones que a su vez subsanan los derechos humanos, por lo que se cae en una tramposa legitimación de las democracias. El Estado, aunque democrático, tiene sexo y eso le hace generar cierto tipo de exclusiones relacionadas con la población LGBT; por consiguiente, el objetivo de este trabajo es analizar los caminos que se han tomado en la construcción de los derechos humanos para las personas LGBT, dentro de los contextos democráticos, y si estos son los más idóneos para romper con el orden heteronormativo, patriarcal y binario que apuntala la discriminación hacia estas poblaciones en el día a día, así como discutir las respectivas limitantes.
Envejecimiento y género: Reconstruyendo los roles sociales de las personas mayores en los cuidados
Authors: Piña Morán Marcelo , Gómez Urrutia Verónica
Published: July 2019

Este artículo aborda el tema de los roles sociales de las personas mayores desde la perspectiva de la gerontología social y, específicamente, la gerontología rupturista. La propuesta enfatiza la naturaleza diferenciada por género del envejecimiento, utilizando como eje de la discusión la temática de cuidados. Se argumenta que una (re)construcción inclusiva de los roles sociales en esta fase de la vida requiere plantear una ruptura con la mirada tradicional de las personas mayores como receptores pasivos de política dirigidas a ellos/as, en aras de considerar la necesidad de levantar información sobre la valoración subjetiva que los individuos realizan de la situación social en que los pone la vejez, las potencialidades de este periodo y los roles asociados a ella.

Published: July 2019

Resveratrol is a polyphenolic compound that exhibits antiinflammatory and cardioprotective properties. In this study we investigated the protective role of resveratrol on the inflammatory activation of macrophages during pathogenesis of atherosclerosis. Macrophage Ana-1 cells were stimulated by cholesterol and resveratrol, and the cell culture supernatant was collected to treat human umbilical vein endothelial cells (HUVECs). The release of IL-1? into the Ana-1 cell supernatant was quantified by ELISA. Expression of the adhesion molecule ICAM-1 and E-selectin in HUVECs were examined by Western-blotting. Additionally, the adhesion of monocytes in HUVECs under different conditions was tested by cell adhesion analyses. The results indicated that the high cholesterol treatment increased the expression level of IL-1?, while pretreatment with resveratrol inhibited this induction of IL-1? in Ana-1 cells. Resveratrol inhibited the adhesion of monocytes to the endothelium at least partly through inhibition of IL-1? expression in macrophages. Moreover, the expression level of caveolin-1 significantly increased after the pretreatment with resveratrol, indicating that resveratrol enhances reverse cholesterol transport (RCT) in macrophages. Our study indicated that resveratrol has significant antiinflammatory effects and can be considered as a candidate molecule to prevent atherosclerosis.

Study on the removal of NO from flue gas by wet scrubbing using NaClO3
Authors: Shi Deqi , Sun Guoxin , Cui Yu
Published: July 2019

In order to remove nitric oxide (NO) from flue gas, from small coal-fired boilers, it is necessary to exploit the cost-effective wet denitration technology. The absorption of NO with sodium chlorate solution was studied. The effects of experimental conditions, such as temperature, NaClO3 concentration, type of acid, mole ratio of NaClO3 to hydrogen ions, on NO removal rate were investigated, and the optimal conditions were established. As the effect of temperature on denitration was related to the type of acid used, the temperature required for sulfuric acid was high, and the temperature required for nitric acid was low. The optimal mole ratio between NaClO3 and the two types of acids was the same. The reaction products were analyzed by ion chromatography. The reacted solution could be recycled after the removal of sodium chloride. The reaction mechanism and the total chemical reaction equation of NaClO3 denitration were deduced. The thermodynamic derivations showed that this oxidation reaction could proceed spontaneously and the reaction was very thorough. NaClO3 exhibited high NO removal efficiency and its denitration cost was much lower than sodium chlorite.

The aim of this work was to investigate a possibility of preparing composite zein/natural resin (shellac and rosin) nanoparticles by antisolvent co?precipitation from their aqueous ethanol solutions. Influence of zein/resin mass ratio (1/0, 0.8/0.2, 0.5/0.5, 0.4/0.6 and 0/1) and pH (2?12) on particle size, d, and zeta potential, ?, of the prepared particles was studied. The functional properties of zein/rosin composite nanoparticles were evaluated by studying carvacrol encapsulation. It was shown that the antisolvent precipitation can be successfully used to prepare the shellac and rosin nanoparticles, as well as the composite zein/shellac and the zein/rosin nanoparticles. Colloidal properties, d and ?, of the obtained nanoparticles are influenced by the zein/ /resin mass ratio and the pH of nanoparticles? dispersions. The isoelectric point of composite nanoparticles can be modulated by varying the zein/resin mass ratio. It was found that the zein/rosin nanoparticles are suitable for carvacrol encapsulation, where carvacrol release is enhanced by increasing the rosin share in the composite zein/rosin nanoparticles.

The development of new electrocatalysts for the oxygen reduction reaction (ORR) is crucial for the sustainable energy economy. Both fundamental understanding of surface processes under operating conditions and suitable ORR activity measurements are necessary to select the best electrocatalyst candidate. In the present study, to contribute to this matter, we show that both the nature of alkali metal cations (Li+, Na+ and K+), composing supporting aqueous hydroxide solution, as well as the potential sweep rate in rotating disk electrode voltammetry measurements, influence the results of measurements of ORR activities of N-containing nanocarbons. Based on density functional theory calculations, we concluded that the specific interactions of hydrated cations with oxygen functional groups are responsible for such behaviour, leading to a close interplay between the electrode double layer charging and the parallel Faradaic process on carbon surface. From a practical point of view, the presented results indicate that it is necessary to standardize carefully the ORR measurements on different carbon materials.
Relation between health and wages in Turkey
Authors: Alcan Sezer , Özsoy Onur
Published: July 2019

The purpose of this study is to estimate the effects of health on the hourly wages of women and men in Turkey by using panel data. The data are used to estimate the earning function, where the natural logarithm of hourly wage is the function of individual characteristics, including health. This work complements previous studies by using a panel in which the education variable, measured by the degree obtained, varies over time and therefore it can be estimated through the within estimator. One of the most important observations of this study is that very good and/or good self-assessed health status has a positive effect on wages more for women than for men. Another important finding is that of significant difference in the rate of return to education, which is higher for women than for men.
Monetary policy and bank lending in euro area since the outset of the global financial crisis
Authors: Wierzbowska Agata
Published: July 2019

In this article, we present the impact of the monetary policy stance of the European Central Bank (ECB) since 2007 on bank lending in the euro area and compare the effects of the main measures: interest rate changes, liquidity provision, and asset purchase programmes. We also analyse the channels through which monetary policy might influence the banking system and narrow our focus to the individual countries. The main results indicate stimulating impact of ECB?s policy stance on bank lending that extends its influence mainly through interest rate cuts further supported by the liquidity provision and asset purchase programmes. However, we also find considerable differences across the member states, often depending on the state of the banking system and loan demand in the member state. The results support the variety of monetary policy measures introduced by the ECB, as each played its own role in supporting the banking system and encouraging bank lending in the euro area.
Lagrange duality and saddle point optimality conditions for semi-infinite mathematical programming problems with equilibrium constraints
Authors: Singh Kunwar , Maurya J.K. , Mishra S.K.
Published: July 2019

In this paper, we consider a special class of optimization problems which contains infinitely many inequality constraints and finitely many complementarity constraints known as the semi-infinite mathematical programming problem with equilibrium constraints (SIMPEC). We propose Lagrange type dual model for the SIMPEC and obtain their duality results using convexity assumptions. Further, we discuss the saddle point optimality conditions for the SIMPEC. Some examples are given to illustrate the obtained results.

OBJECTIVE

Microvascular complications are common among patients with diabetes mellitus (DM). The presence of heart failure (HF) is presumed to be due to macrovascular disease (typically HF with reduced ejection fraction [HFrEF] following myocardial infarction). We hypothesized that HF with preserved ejection fraction (HFpEF) in patients with DM may be a manifestation of microvascular disease compared with HFrEF. The objective of this study was to examine the prevalence and association with clinical outcome of microvascular complications in patients with HF and DM.

RESEARCH DESIGN AND METHODS

We investigated the prevalence, association with clinical outcome, and cardiac structure and function of microvascular (neuropathy, nephropathy, and retinopathy) complications of DM in 2,800 prospectively enrolled participants with HF and DM (561 with HFpEF) from the Asian Sudden Cardiac Death In Heart Failure (ASIAN-HF) registry.

RESULTS

A total of 601 (21.5%) participants with DM had microvascular complications. Participants with DM and any (one or more) microvascular complications were more likely to have HFpEF (odds ratio 1.70 [95% CI 1.15–2.50]; P = 0.008). Furthermore, the likelihood of having HFpEF increased with an increasing number of microvascular complications (Ptrend < 0.001). Microvascular complications were associated with more left ventricular (LV) hypertrophy and a greater reduction in quality of life in HFpEF than HFrEF (Pinteraction < 0.001 for all). Compared with participants with DM and without microvascular complications, the adjusted hazard ratio for the composite outcome of all-cause death or HF hospitalization was 1.35 (95% CI 1.04–1.76) for participants with DM and microvascular complications regardless of HF type (Pinteraction = 0.112).

CONCLUSIONS

Diabetic microvascular disease is more common, and related to greater LV remodeling, more impairment of quality in life, and similar adverse outcomes, in participants with HFpEF compared with HFrEF. HFpEF may be a clinical manifestation of microvascular disease in DM.

ANAK BEKERJA DI INDONESIA: BUKTI EMPIRIS TERHADAP WEALTH PARADOX
Authors: Indrasari Disty Putri Ratna
Published: July 2019

Banyak penelitian mengungkapkan bahwa keluarga yang semakin miskin akan menyebabkan kejadian anak bekerja lebih banyak (luxury axiom). Akhir-akhir ini, peneliti sudah mulai melihat adanya kondisi dimana keluarga yang mempunyai banyak tanah (keluarga yang lebih kaya), justru membuat fenomena anak bekerjanya lebih banyak (wealth paradox). Kondisi wealth paradox dibayangkan menjadi paradox dari kondisi luxury axiom. Namun demikian, kondisi wealth paradox sebenarnya dapat diintegrasikan ke dalam kondisi luxury axiom. Banyak penelitian tentang anak bekerja di Indonesia yang spesifikasi empirisnya belum dapat menangkap adanya kemungkinan perilaku wealth paradox dan luxury axiom, sehingga penelitian ini mencoba memberikan kontribusi perilaku anak bekerja di Indonesia dengan menggunakan spesifikasi empiris yang dapat menangkap perilaku wealth paradox dan luxury axiom. Penelitian ini bertujuan bertujuan untuk menguji hipotesis wealth paradox dan luxury axiom terhadap anak bekerja di Indonesia dengan menggunakan data IFLS 5. Model yang digunakan di sini adalah tobit dengan instrumental variable. Penelitian ini berhasil membuktikan secara empiris bahwa perilaku wealth paradox dan luxury axiom juga terjadi dalam konteks anak bekerja pada keluarga pertanian di Indonesia.

Hasil penelitian menunjukkan bahwa faktor-faktor yang mempengaruhi produksi bawang merah secara nyata di Kabupaten Majalengka adalah luas lahan, jumlah bibit, dan pestisida. Untuk hasil analisis efisiensi alokatif menunjukkan bahwa rata-rata petani bawang merah di Kabupaten Majalengka masih belum efisien, namun dari kelima faktor produksi yang digunakan oleh responden terdapat satu faktor produksi yang tidak efisien secara alokatif. Oleh karena itu, dalam meningkatkan efisiensi alokatif dari setiap faktor produksi yang digunakan dalam usahatani bawang merah, maka petani perlu diberikan pendampingan untuk dapat menekan biaya produksi dan meningkatkan pendapatan.
Substrate inhibition and pH effect on denitritation with granular biomass
Authors: Kecskésová Stanislava , Imreová Zuzana , Kožárová Bibiána , Derco Ján , Drtil Miloslav
Published: July 2019

Undissociated HNO2 (up to 2 mg dm−3) was confirmed as substrate inhibitor for granular biomass from a denitritation upflow sludge bed reactor used for biological removal of nitrite. On the contrary, total nitrite nitrogen (N-NO2 up to 500 mg dm−3) and methanol (COD up to 2000 mg dm−3) were not proven to be inhibitors. pH also affected the denitritation efficiency (optimal pH was 5.9). Reduction of HNO2 concentration in the reactor by effluent recycling is recommended.
Agile manoeuvres using model predictive control
Authors: Fedorová Kristína , Bakaráč Peter , Kvasnica Michal
Published: July 2019

This paper shows how model predictive control (MPC) can be used to perform agile manoeuvres in a pendulum-on-a-cart system, which is an abstraction of many mechanical systems commonly used in the industry, such as cranes. Specifically, the problem of moving a cart on which a pendulum is mounted using a free joint is rapidly moved from one position to another one while mitigating the swings of the pendulum. To achieve this goal, an optimization-based MPC strategy is employed that selects the control moves while minimizing the chosen cost function and, simultaneously, enforcing constraint satisfaction. As the controlled system is nonlinear, two options are considered. The first one solves the nonlinear MPC problem in an approximate fashion using the so-called random shooting approach. The second method is based on the first one approximating the nonlinear system by a linear one, followed by applying convex MPC techniques. The performance of both strategies was compared by means of real-time experiments.
