Abstract
Thermoelectric fly ash was used as a micronutrient source for microorganisms in the anaerobic digestion process of thermally pretreated (1 hour, 120 °C) secondary sludge. The obtained results not only suggest that fly ash improves methane generation in the conversion of volatile fatty acids into methane, but also show a new observation, that the fly ash contributes in the particulate organic solubilization. The maximum methane production rate increased from 6.52 mL/L/d to 22.59 mL/L/d when fly ash was added at a dosage of 150 mg/L in biochemical methane potential tests compared with tests with no added ash. Additionally, the kinetic constants of the hydrolysis of particulate organic matter were obtained in both cases (with and without added ash) in batch reactors using a first-order kinetic model; in the case of no addition, the first-order kinetic parameter was 0.019 ± 0.002 d−1, while with ashes this value increased to 0.045 ± 0.000 d−1. Therefore, the addition of fly ash improves methane generation and hydrolytic kinetics in different orders of magnitude.

Vibration Analysis Of a Self-Excited Elastic Beam
Authors: Barrón-Meza M. A. 
Published: November 2019

The vibration behavior and the energy exchange among the normal modes of a clamped-free self-excited elastic beam are analyzed in this work. To model this kind of beam, the damping term of a van der Pol oscillator is directly added to the equation of a linear elastic beam, yielding a single nonlinear partial differential equation. To solve this equation, a spectral method is employed. Three vibration modes are considered in the analysis, and the values of the self-exciting constant are varied in order to cover from linear to nonlinear vibration behavior. Multiple frequencies of the nonlinear beam are determined through the power spectral density of the beam free-end time series. Given that this relatively simple model mimics at least in a qualitative way some key issues of the fluid-structure problem, it could be potentially useful for fatigue studies and vibration analysis of rotating blades in turbomachinery.

Published: November 2019

The objective of this paper is to propose the methodology for the implementation of strategic plans in organizations through the prevention and, in its case, the definition and solution of the problems that frequently affect the implementation processes with many negative manifestations and harmful consequences. By elaborating the concept of implementation under the systems approach and cybernetic paradigm, two types of these problems have been identified: the organizational and the functional ones. The consequent analysis of each kind of them has permitted the development of a methodology for their prevention, identification and solution to assure an effective and efficient implementation process. This methodology consists in realizing five subsequent procedures, which were validated with positive results obtained through their virtual application to the different cases of manifestations with the negative consequences that had occurred during strategic plans implementations described in literature.

Published: November 2019

Today control is required in any field or application. Nowadays, classic control is the most used, but it is well-known that users need to know the system’s characteristics to reach optimal control. This paper is focused on designing a proportional integral derivative control, based on a single artificial neural network with the aim to improve its performance and its use with minimal control knowledge from the end user. The proposed control was assessed with simulated and practical physical systems of first and second order. In order to increase the confidence of the intelligent sensor control, the evaluation was made using the classical test of control response of a step as input. The proposed control was implemented on an intelligent sensor with a small microcontroller. Also, the performance was compared between the proposed control and a commercial control. Here, an intelligent sensor is presented with control capability for a wide variety of physical systems. The experiments performed demonstrated the capability of the proposed control, which can be easily used and save time at the initial control set up.

Published: November 2019

Os tributos possuem impacto direto tanto nas atividades econômicas de uma empresa, quanto no dia a dia do indivíduo. Torna-se necessário o conhecimento da carga tributária brasileira (CTB) para o exercício da profissão com maior eficácia e eficiência, de modo que a inobservância das normas legais e seus reflexos podem conduzi-lo a um fracasso profissional. A pesquisa foi realizada com objetivo de verificar a percepção dos acadêmicos de ciências sociais aplicadas em relação a carga tributaria brasileira, efetuar uma comparação com os alunos ingressante e concluintes. Por meio da aplicação um questionário aos alunos das fases iniciantes e concluintes dos cursos de Contabilidade, Direito e Administração, obteve-se uma amostra de 213 alunos, destes 120 (56%) iniciantes e 93 (44%) concluintes. Para análise dos dados, foi aplicado teste Mann-Whitney para verificar a diferença entre as médias das respostas. Foi possível verificar que condição de concluinte não interferiu significativamente maiores conhecimentos específicos sobre a carga tributária brasileira em maioria das questões especifica apresentadas. Demonstrou-se haver uma lacuna no conhecimento acerca da carga tributária, o que representa um conhecimento inferior aquele esperado para os alunos próximo de concluir sua formação. Sobre a opinião observou-se que os concluintes possuem uma visão mais negativa em relação aos ingressantes. Doravante, cabe ainda um melhor aprofundamento no assunto e aperfeiçoamento dessa reflexão.

OBJECTIVE
Diabetes in older age is heterogeneous, and the treatment approach varies by patient characteristics. We characterized the short-term all-cause and cardiovascular mortality risk associated with hyperglycemia in older age.

RESEARCH DESIGN AND METHODS
We included 5,791 older adults in the Atherosclerosis Risk in Communities Study who attended visit 5 (2011–2013; ages 66–90 years). We compared prediabetes (HbA1c 5.7% to &lt;6.5%), newly diagnosed diabetes (HbA1c ≥6.5%, prior diagnosis &lt;1 year, or taking antihyperglycemic medications &lt;1 year), short-duration diabetes (duration ≥1 year but &lt;10 years [median]), and long-standing diabetes (duration ≥10 years). Outcomes were all-cause and cardiovascular mortality (median follow-up of 5.6 years).

RESULTS
Participants were 58% female, and 24% had prevalent cardiovascular disease. All-cause mortality rates, per 1,000 person-years, were 21.2 (95% CI 18.7, 24.1) among those without diabetes, 23.7 (95% CI 20.8, 27.1) for those with prediabetes, 33.8 (95% CI 25.2, 45.5) among those with recently diagnosed diabetes, 29.6 (95% CI 25.0, 35.1) for those with diabetes of short duration, and 48.6 (95% CI 42.4, 55.7) for those with long-standing diabetes. Cardiovascular mortality rates, per 1,000 person-years, were 5.8 (95% CI 4.6, 7.4) among those without diabetes, 6.6 (95% CI 5.2, 8.5) for those with prediabetes, 11.5 (95% CI 7.0, 19.1) among those with recently diagnosed diabetes, 8.2 (95% CI 5.9, 11.3) for those with diabetes of short duration, and 17.3 (95% CI 13.8, 21.7) for those with long-standing diabetes. After adjustment for other cardiovascular risk factors, prediabetes and newly diagnosed diabetes were not significantly associated with a higher risk of all-cause mortality (hazard ratio [HR] 1.03 [95% CI 0.85, 1.23] and HR 1.31 [95% CI 0.94, 1.82], respectively) or cardiovascular mortality (HR 1.00 [95% CI 0.70, 1.43] and HR 1.35 [95% CI 0.74, 2.49], respectively). Excess mortality risk was primarily concentrated among those with long-standing diabetes (all-cause: HR 1.71 [95% CI 1.40, 2.10]; cardiovascular: HR 1.72 [95% CI 1.18, 2.51]).

CONCLUSIONS
In older adults, long-standing diabetes has a substantial and independent effect on short-term mortality. Older individuals with prediabetes remained at low mortality risk over a median 5.6 years of follow-up.

Sistem pendidikan yang dikemukakan Ki Hadjar Dewantara (ing ngarsa sung tuladha, ing madya mangun karsa, dan tut wuri handayani) adalah wasiat luhur yang patut dijadikan sebagai acuan dalam pengembangan pendidikan karakter. Pendidikan menurut Ki Hadjar Dewantara haruslah bersifat nasional. Artinya, secara nasional pendidikan harus memiliki corak yang sama dengan tidak mengabaikan budaya lokal. Bangsa Indonesia yang terdiri atas banyak suku, ras, dan agama hendaknya memiliki kesamaan corak dalam mengembangkan karakter anak bangsanya. Penyelenggaraan pendidikan jangan terjebak pada pencapaian target sempit yang hanya melakukan transfer pengetahuan, tetapi perlu dengan sengaja mengupayakan terjadinya transformasi nilai untuk pembentukan karakter anak bangsa. Pembentukan karakter peserta didik perlu melibatkan tri pusat pendidikan (keluarga, sekolah, dan masyarakat) secara sinergis. Pengembangan karakter peserta didik perlu memperhatikan perkembangan budaya bangsa sebagai sebuah kontinuitas menuju ke arah kesatuan kebudayaan dunia (konvergensi) dan tetap memiliki sifat kepribadian di dalam lingkungan kemanusiaan sedunia (konsentris).Kata Kunci: Membangun Karakter; Filsafat Pendidikan Ki Hadjar Dewantara

The patterns of marketing in business have changed rapidly. While in the past, marketing was done solely through direct face-to-face transaction, the current existence of the internet leads to alternative options for commercial activities, including by using a Smartphone or gadget, customers can have transactions via various applications. These applications also offer a variety of products, including apparels, food, household needs as well as tertiary needs. To keep with the pace, business actors also change their marketing patterns. In addition to advertise and sell the products through conventional method, the internet becomes the marketing media for business actors. Nevertheless, not all of them are able to change their marketing pattern, especially SMEs. The factors of low educational background and lack of knowledge of the internet, development, and technology are the reasons. Considering this condition, it is suggested for business actors to change their marketing pattern according to the developments and technological advances in the community in order to survive.

The purpose of this study was to find out and analyze the strengths, weaknesses, opportunities and threats encountered by the Indonesian Red Cross (PMI) in carrying out disaster risk reduction in the Padang City. The method used in the study is descriptive qualitative method with data collection techniques through interviews and documentation studies. Data were analyzed using SWOT analysis. This research shows that the strengths are, PMI has reliable personnel and specialists in their fields, PMI has a stable procedure and system, PMI has its own law, namely Law No. 1 of 2018 and Government Regulation No. 7 of 2019. The disadvantage is that PMI is a voluntary organization so that in carrying out its duties PMI cannot be too forced and not too binding, PMI does not have a budget for risk reduction so it is difficult to carry out operational activities, infrastructure and equipment in PMI are incomplete, PMI personnel quantity still less especially the stanbey at headquarters. The opportunity that PMI has in carrying out disaster risk reduction, namely PMI, has gained trust from the government, the PMI name is quite good in the government and society. The threat is that community participation is still lacking when conducting socialization activities on disaster risk reduction, PMI is used as political land by certain elements of the external PMI, causing internal conflicts and influencing PMI's performance. The efforts made by PMI in conducting disaster risk reduction in the Padang City by conducting a new volunteer open recruitment if the volunteers have begun to be less active, provide training in advance to the team that will take to the field to provide socialization so that it is more prepared and the information delivered is more dense and quality, maintaining communication with the same stakeholders engaged in disaster management, conducting regular and periodic meetings to maintain communication and facilitating coordination among fellow stakeholders, calling on the public to always participate in socialization activities or simulations held by PMI and other stakeholders.

Published: November 2019

ABSTRACT

Although the consciousness of Integrated Reporting (IR) is increasing within Malaysian companies, how IR creates value for their business is not completely understood. This paper attempts to investigate the potential contribution of IR implementation to the financial performance of the top 50 Malaysian public listed companies during the period of 2012 to 2015. The eight (8) IR content elements from the International Integrated Reporting Council (IIRC) framework are examined to predict the adoption rate of IR in relation to financial performance. This includes disclosure on organizational overview and external environment, governance, business model, risks and opportunities, strategy and resource allocation, performance, outlook, and basis of preparation and presentation. The data indicates that Malaysian PLCs reported more than 50% for every content element, except Basis of Preparation and Presentation (CE8). Data analysis indicates that among the eight (8) content elements, four (4) of them, namely governance, business model, risks and opportunities, and performance disclosure, have significant positive impact on financial performances. The finding of this paper provides insight into the contribution of IR in effecting the maintenance of business resilience and competitiveness in a fluctuating market. Therefore, this paper provides a significant impetus for implementation of IR among the Malaysian companies.

Published: November 2019

This article deals with the growing pressures and demands for emerging risk reporting that may help interested users assess the importance of social risk management for sustainable development. The objectives of this study were to examine the influence of individual and institutional ownership and stakeholders on social risk disclosures and the joint effects on firms’ financial performances. A content analysis on the 2013 and 2014 annual reports of all plantation companies was carried out and analyzed using partial least square (SEM_PLS) software version 3.2. Based on the tests, we found significant relationships between institutional ownership and the number of stakeholders with social risk disclosures. However, there were no significant relationships between individual ownership and social risk disclosures. In addition, we found significant relationships between social risks and firms’ financial performances. These findings revealed that institutional shareholders and the number of stakeholders had a significant influence in deciding the disclosure of social risk information. Interestingly to note that social risk information was found to be statistically significant on firms’ financial performance as measured by the firms’ net profits. This paper, therefore, endorsed the growing demand to fully embed social risk management in companies’ operations by both institutional shareholders and stakeholders in general.
