Objetivo: Identificar os fatores que influenciam na qualidade da informação contábil das maiores empresas listadas na BM&Bovespa.

Método: Pesquisa realizada em uma amostra composta por 100 companhias abertas. A qualidade da informação foi analisada por meio de um índice desenvolvido por Fathi (2013), composto por 78 itens e que contemplam informações obrigatórias e voluntárias. Os fatores determinantes observados foram governança corporativa, empresa de auditoria, existência de comitê de auditoria, concentração acionária, investidores institucionais e internacionalização da empresa.

Resultados: Os resultados revelaram um índice médio de evidenciação equivalente a 78%. A maioria das companhias estavam listadas em níveis diferenciados de governança; eram auditadas por big four e possuíam Comitê de Auditoria. O percentual médio de concentração acionária foi 41,37%; em 44% delas havia investidores institucionais no quadro acionário; e apenas 19% negociavam ações em bolsa americana. Em relação aos fatores determinantes, verificou-se que o fato de a empresa ser auditada por big four; possuir Comitê de Auditoria; possuir participação acionária de investidores institucionais; e negociar ações em bolsa americana reflete-se em informações divulgadas de melhor qualidade.

Contribuições: Os achados fornecem evidências adicionais para a literatura existente, além de serem relevantes para os diversos usuários das informações contábeis, tais como analistas e investidores.

Authors: D'Souza Márcia Figueredo , Jones Daniel Nelson
Published: August 2017

Objetivo: Characterize the scientific research of the Dark Triad, elucidating the direction of this theme, in the context business and accounting, in the period from 2012 to 2014.

Método: For this research, a socio-bibliometric survey was used as the research strategy, based on the observation of contents in two sources: the Portal Periódicos Capes and the Web Science Knowledge. The study sample included 90 articles, illustrated by scientific networks. At the end, the taxonomy was elaborated for the 12 studies that discussed the Dark Triad construct.

Resultados: Concerning the focus of the articles, Narcissism is the most explored trait and is associated with leadership and corporate decision making. Psychopathy attracts the researchers’ attention to the leader’s aversive behavior in the corporate midst. Machiavellianism receives greater emphasis in research on manipulation. Specifically in the accounting area, the majority associates the traits with unethical behavior, tending towards fraud in the financial reports.

Contribuições: The results appointed opportunities for research using the traits of the Dark Triad, particularly in view of the interdisciplinary nature and scientific relevance of this theme, which accounting researchers have hardly explored. In addition, they are noteworthy for leaders to reflect on their own and their employees’ attitudes in the corporate sphere.

Published: August 2017

The aim of the research is to study the state of sensory functions in infants who were born and living in the Lugansk and Donetsk during the military conflict. Materials and methods. A dynamic clinical examination was made. Also it was made the assessment of the rate sensory development in 65 children in the area of military conflict. Among them 32 children were breast-fed, the main group of children (MGCh), and 33 children who were bottle-fed, formed the comparison group (CGCh). The control groups of our study consist of 73 children: 36 children (CGCh) who were breast-fed, and 37 children who were bottle-fed. There was a control group of comparison children (CGCCh) outside the zone of military conflict. The assessment of the level of sensory development of children was carried out using a standardized clinical-psychological techniques “Gnome”. Conclusions: the military conflict adversely affects the sensory development of children who were precisely in the area of conflict. The weakest spot was auditory function of children. It indicates the auditory hypersensitivity. The second place in terms of violations takes the reflex tactile sensitivity, the level of which depends on the age of the child and type of feeding. Breastfeeding is a powerful shock absorber of distressful influences of the military acts, that taking place in the environment of children. Children who have experienced the stress of war need the necessary rehabilitation measures.
Electronmicroscopic examination of myometrium scar after use of monoand bipolar cauters
Authors: Kupatadze Dimitry D , Safronova Margarita M , Il'inskaya Yevgeniya V
Published: August 2017

Uterine fibroids, which, according to various estimates, are found in 50% of cases, is the most common benign disease of the female genital area. A radical method of treating this disease is surgical removal. In radical operations are actively used bi- and monopolar cauters, both for cutting and for coagulation. After such an exposure necrotic scars are often formed, leading to gross deformations of the tissue and, as a consequence, to the impossibility of a normal onset and course of pregnancy. The question of studying postoperative myometrium scars at the ultrastructural level, with the aim of possible optimization of physical parameters for the most gentle operation, is highly important, since allows to estimate changes in tissues at the level of cellular and subcellular structures. At the moment, this experience is absent in our country. The electron microscopic investigation of a myometrium subjected to an electric current is considered in the article.

Published: August 2017

Background: The aim of the study was to determine the number of parathyroid glands that need to be preserved to prevent hypoparathyroidism and to understand the relation between the number of parathyroid glands preserved and hypoparathyroidism.Methods: A retrospective study was performed on 350 patients who had undergone trans cervical total thyroidectomy with or without neck dissection for papillary thyroid carcinoma between July 2010 to August 2015.Results: Incidental parathyroidectomy occurred in 19.1% of patients, one parathyroid gland in 17.8%, two in 2% and 3 in 0.5%. Transient hypoparathyroidism increased when incidental parathyroidectomy occurred on multivariate regression analysis, but it was not influenced by the actual number of parathyroid glands removed. There was no relationship between the number of parathyroid glands preserved and hypoparathyroidism.Conclusions: It is not compulsorily required to prevent permanent hypoparathyroidism, but the preservation of all the four parathyroid glands during thyroidectomy decreases the incidence of transient hypoparathyroidism. When auto transplantation is not performed, to prevent permanent hypoparathyroidism, preserving at least one parathyroid gland with an intact blood supply is sufficient.

Dwa rodzaje pozytywności prawa
Authors: Leszczyński Jerzy
Published: August 2017

Rozumienie prawa jako prawa pozytywnego skutkuje teoretycznym problemem wyjaśnienia fenomenu judykatury jako czegoś odrębnego od prawa pozytywnego. Odmienność perspektyw tworzenia i stosowania prawa powoduje, że pozytywność (określoność) prawa przedstawia się w nich różnie. Pozytywność prawa jako efekt stanowienia to pozytywność tekstu prawa, natomiast pozytywność prawa, które jest zastosowane, to pozytywność treści prawa. Niewspółmierność tych przejawów pozytywności prawa pozwala zachować zasadniczą spójność pojęcia prawa.
Pozytywna wartość osobowości. Pawła Nowgorodcewa idealizm prawny
Authors: Daniłkina Natalia
Published: August 2017

Paweł Nowgorodcew był profesorem prawa, działaczem politycznym i jednym z czołowych przedstawicieli rosyjskiej filozofii prawa. Na przełomie wieków XIX i XX zauważył kryzys doktryny pozytywizmu prawniczego i wzrost zapotrzebowania na nową filozofię prawa, którą utożsamiał z doktryną prawa naturalnego. Według Nowgorodcewa nowa doktryna prawa naturalnego miała zawierać w sobie zbiór ideałów moralnych w stosunku do treści prawa pozytywnego. Swoją koncepcję autor ten budował na fundamencie szeroko pojmowanego idealizmu filozoficznego: od Kanta do filozoficznie „zmodernizowanej” rosyjskiej ortodoksji chrześcijańskiej. W artykule przedstawiono zarys filozofii prawa Nowgorodcewa i ujawniono jej cechy szczególne w porównaniu z wybranymi teoriami zachodnioeuropejskimi, a także w związku z wyraźną tendencją personalistyczną w filozofii rosyjskiej.
Natural User Interface for Education in Virtual Environments
Authors: Stavrev Stefan
Published: August 2017

Education and self-improvement are key features of human behavior. However, learning in the physical world is not always desirable or achievable. That is how simulators came to be. There are domains where purely virtual simulators can be created in contrast to physical ones. In this research we present a novel environment for learning, using a natural user interface. We, humans, are not designed to operate and manipulate objects via keyboard, mouse or a controller. The natural way of interaction and communication is achieved through our actuators (hands and feet) and our sensors (hearing, vision, touch, smell and taste). That is the reason why it makes more sense to use sensors that can track our skeletal movements, are able to estimate our pose, and interpret our gestures. After acquiring and processing the desired – natural input, a system can analyze and translate those gestures into movement signals.

Environmental Accounting (EA) practices have developed rapidly in some countries and have a positive impact on their organizations. Sustainability report (SR) as an indicator of EA practices helps company gain a better reputation and it is set by management. However, some ASEAN countries including Indonesia do not have relevant accounting standards on the environment. EA practice is still not widely known in Indonesia, although, internationally there have been standards that provide guidelines for aspect of the environment such as the Global Reporting Initiative (GRI). Another aspect in GRI is remuneration. Remuneration is part of personnel cost which is a motivation about the positive effects of EA practices to disclose management concern. This research introduces a tool to evaluate a remuneration structure and the consistency of EA practices in the Sustainability Report.

PROJETOS DE ESCOLARIZAÇÃO E INGRESSO DE ESTUDANTES NEGROS NA UNIVERSIDADE EM CONTEXTO DE AÇÕES AFIRMATIVAS
Authors: Mongim Andrea Bayerl
Published: August 2017

Neste artigo busco analisar, com base em pesquisa etnográfica, projetos de escolarização construídos por discentes negros e oriundos de famílias consideradas de baixa renda que ingressaram na Universidade Federal do Espírito Santo, mediante sistema de reserva de cotas. O implemento de ações afirmativas para ingresso no ensino superior tem assumido lugar de fundamental importância para a efetivação de projetos de escolarização destes estudantes em nível superior. No entanto, além das dificuldades de ordem material presentes no processo de efetivação de tal projeto, são também amplos e significativos os desafios de ordem simbólica. No processo de ingresso e permanência na universidade tem-se observado concepções e práticas discriminatórias e excludentes, por parte de grupos, de agentes institucionais ou nas relações interpessoais. Por esta via, conclui-se que as concepções de justiça subjacentes às políticas de ação afirmativa, propulsoras da objetivação do projeto de ingresso na universidade, não são observadas no que se refere à permanência e conclusão do curso superior.

Temos a satisfação de apresentar ao público o novo número da Revista Contemporânea de Educação (RCE), que conta com a publicação do número temático Educação das relações étnico-raciais e educação em comunidades remanescentes de quilombos. Com este número temático, a RCE pretende contribuir para o aprofundamento e a difusão de conhecimento sobre desafios que permanecem na educação brasileira quando tratamos de desigualdades e da diversidade étnico-racial. Tomamos como ponto de partida o reconhecimento dos avanços importantes nesta temática, no Brasil, nas últimas décadas. A partir dos anos 1990, principalmente com a mobilização do movimento negro, passaram a ser incorporadas preocupações com a questão da diversidade étnico-racial na educação. Esse processo se fortaleceu com a sanção da Lei nº 10.639/2003, que modificou a Lei de Diretrizes e Bases da Educação Nacional (LDB) para incluir o ensino de história e cultura afro-brasileira e africana na educação básica brasileira. Desde então, houve importantes avanços na inclusão desta agenda na educação básica através da ampliação da oferta de livros de literatura infantil com tal temática, bem como da promoção crescente de mecanismos de capacitação de professores nesse campo. A efetiva implementação da lei, entretanto, ainda está cercada de inúmeros desafios, principalmente no que diz respeito à sua incorporação como atividade permanente e de caráter interdisciplinar no currículo escolar. Também identificamos desafios referentes à formação inicial e continuada de professores de diferentes campos de conhecimento para que eles possam incorporar a perspectiva da diversidade étnico-racial no seu trabalho cotidiano.

Authors: Singh Ganpat , Goel Arun , Choudhary Mahender
Published: August 2017

In this paper, significant variables of domestic urban water demand required for the purpose of estimation of urban water supply in five planned colonies of the City of Ajmer, Rajasthan, India, are identified. The data for these 16 variables are entered in the multiple linear regression (MLR) (stepwise) models in SPSS software, and domestic water demand models are developed. Based on these models, the six most significant variables, namely temperature (T), rainfall (RF), family size (FS), family income (FI), number of bathrooms (NB), and age of house (AH), are identified. The data of 16 variables are further utilized in principal component analysis (PCA), and five factors/variables are extracted, comprising combinations of these 16 variables. A regression coefficient of 0.76 is obtained in the PCA model. These six significant variables are further fed into a multilayer perceptron neural network (NN) model for water demand forecasting. The linear regression coefficient of NN is 0.90, very close to the MLR (stepwise) coefficient of 0.89, and verifying the dependence of water demand on these six variables. The outcome of the study suggests that the six variables are significant for estimation of water demand for Ajmer.
Effect of television broadcasts of global sporting events on short-term changes in the use of water from the water supply network
Authors: Marszelewski Włodzimierz , Piasecki Adam
Published: August 2017

The article discusses the influence of television broadcasts of global sporting events on water usage in the city of Toruń during the final match of the FIFA 2014 World Cup in Brazil. The analyses covered accurate data of water usage (recorded every 1 minute) in the city on the day of the final match. The obtained results were compared with the data for the same days of the week (Sundays) but with no such important events. A completely different trend in water usage was documented during the television broadcast, including: exponential and short-term increases and decreases in water demand immediately after the end of the successive parts of the football match. The deviations in water usage from the normal trend for the same day of the week and the same hours ranged from −318 to more than 550 m3·h−1 (calculated on an hourly basis). Therefore, water usage can be a good indicator of the interest of audiences in television programmes, particularly in those gathering millions of viewers, such as broadcasts of global sporting events.
Genetic diversity of Escherichia coli isolates from surface water and groundwater in a rural environment

Published: August 2017

The genetic characteristics among Escherichia coli strains can be grouped by origin of isolation. Then, it is possible to use the genotypes as a tool to determine the source of water contamination. The aim of this study was to define water aptitude for human consumption in a rural basin and to assess the diversity of E. coli water populations. Thus, it was possible to identify the main sources of fecal contamination and to explore linkages with the hydrogeological environment and land uses. The bacteriological analysis showed that more than 50% of samples were unfit for human consumption. DNA fingerprinting analysis by BOX-PCR indicated low genotypic diversity of E. coli isolates taken from surface water and groundwater. The results suggested the presence of a dominant source of fecal contamination. The relationship between low genotypic diversity and land use would prove that water contamination comes from livestock. The genetic diversity of E. coli isolated from surface water was less than that identified in groundwater because of the different hydraulic features of both environments. Furthermore, each one of the two big strain groups identified in this basin is located in different sub-basins, showing that hydrological dynamics exerts selective pressure on bacteria DNA.
Reactor performance and membrane fouling of a novel submerged aerobic granular sludge membrane bioreactor during long-term operation
Authors: Li Jianfeng , Liu Yanjun , Li Xiaoning , Cheng Fangqin
Published: August 2017

The aerobic granular sludge membrane bioreactor (AGS-MBR) has the potential for simultaneous carbon/nitrogen removal and membrane fouling mitigation. Most studies have focused on comparison of granular sludge MBR and flocculent sludge MBR in short-term tests using synthetic wastewater. In this study, two identical AGS-MBRs were developed, and the reactor performance and membrane fouling were examined systemically over 120 days for synthetic wastewater and municipal sewage treatment, respectively. Results showed that regular granules with good settling ability were developed and maintained throughout the experimental period. Regardless of the substrate type, AGS-MBR demonstrated a stable removal of carbon (85–95%) and nitrogen (50–55%) in long-term operation. In addition, the membrane fouling propensity is apparently lower in AGS-MBRs with no membrane cleaning for 4 months at a flux of 20 L m−2h−1. The filtration resistance analysis indicates that the main membrane resistance was caused by irreversible fouling in both of the reactors. Membrane foulant analysis indicates that proteins in extracellular polymeric substances are more prone to be attached by the membrane of AGS-MBRs because of their hydrophobic nature. This study shows that AGS-MBR is effective and stable for municipal sewage treatment and reuse during long-term operation.
Water management and sustainability of water resources
Authors: Stevović Svetlana , Nestorović Žarko , Lutovac Mitar
Published: August 2017

As a limited resource, especially under market conditions, water should be managed at the highest level of efficiency. This approach, however, leads to a conflict with the sustainability principle. At the basic level it could be defined as a question: ‘Is the market eager to pay the sustainability cost?’ If it is, then the cost of sustainability shall be determined and explicated in the price of water unit delivered to the customer. If not, sustainability is then jeopardized. The solution to this conflict may be a test from a responsible aspect for the current generation towards water resources. This paper aims to research the management of water resources methods from the aspect of sustainability under the conditions of uncompleted and uncertain information. In this paper, the model for water resources availability forecasting is analysed from the aspect of different influences.
Analyzing the risk factors of private–public partnerships for water supply projects using fuzzy synthetic evaluation: a case study of Iranian water supply projects
Authors: Rezaeenour Jalal , Mousavi-Saleh Mohammad , Kolahkaj Abdol Rahman
Published: August 2017

To compensate for the lack of funds for investment in private sector and infrastructure projects, governments may propose public–private partnerships (PPPs) to be able to use share capital and establish the necessary infrastructure of the country. The current study was undertaken to identify and determine the risk factors in PPPs for water supply projects in Iran. After identifying the risk factors using failure mode and effect analysis (FMEA), the risk priority number of each was assessed. This identified the most critical risk factors, which were then categorized into experimental, legal, financial, and technological subcategories. The fuzzy synthetic evaluation (FSE) technique and FMEA method were then blended and the FSE technique was modified for measuring the overall risk level. The computational results show that the levels of risk were ranked as follows (highest to lowest): financial, experimental, technological and legal. The level of risk in the financial subcategory was 6.11, in the experimental was 6.05 and in the technological and legal was 5.94 and 5.83, respectively. The overall risk level in PPPs for Iranian water supply projects considering linguistic variables as the criteria was 5.98, which is high. This level of risk confirms the applicability and suitability of the model.

Authors: Sidik Arif
Published: August 2017

Konaweeha watershed is the largest watershed in Southeast Sulawesi with Konaweeha River as the main river. The main issues in Konaweeha Watershed is floods that occur caused damage to infrastructure and public facilities, lowering agricultural production, and cause fatalities. One of the government's efforts to cope with the flooding problem in Konaweeha Watershed is planning the construction of multi-purpose dams in the upstream of Konaweeha Watershed that is Pelosika Dam and Ameroso Dam. Necessary to study the flood control performance of the two dams. Analyses were performed with hydrologic-hydraulic modeling using HEC-HMS software (Hydrologic Modelling System) version 4.0 and HEC-RAS (River Analysis System) version 4.1. The design rainfalls that were used as input to the model were 2 year, 5-year, 10-year and 25 year. Scenarios used in this study are: (1) Existing Scenario (2) Pelosika Dam Scenario; (3) Ameroro Dam Scenario; (4) Pelosika and Ameroro Dams Scenario. The results showed the maximum water surface elevation along the downstream of Konaweeha River in Scenario (2) and (4) were almost the same in the 2 and 5 years return period design flood. However, in case of 10 and 25 years return period, the difference of maximum water surface elevation at downstream of Konaweeha River was slightly significant. Furthermore, the damping efficiency of the peak discharge (at Probably Maximum Flood or PMF) was found to be 71.70% and 18.18% for the individual Pelosika Dam and Ameroro Dam respectively. Further discussion suggests the development of Pelosika Dam as the higher priority rather than that of the Ameroro Dam.

Authors: Putro Sukma Sayono
Published: August 2017

Gajahwong River is one of the nine rivers in the Special Region of Yogyakarta Province. During dry season,its water quantity has been decreasing so the water flow is insufficient to dilute the pollutant from sewage and affecting the water quality. Some pollutant parameters that have exceeded the quality standard in the Gajahwong river are including BOD, COD, TSS, phosphates, and total coliform. The study is expected to show the relationship between the water quantity and water pollution parameters and how to mitigate it. Water availability at the river was analyzed by using Mock model and the result was presented in flow duration curve. Climate data including rainfall for 12 years period from 2001 to 2012 were collected.Thecondition ofriver water quality was analyzed using Pollution Index Method. Results show that dependable flow at 80% probability was 0.80 m3/s. Water quality conditions in the Gajahwong River from upstream to downstream have declined at moderately polluted level. During 2007 to 2012 the level of TDS, TSS, DO, COD, detergents, oils, and fats, and fecal coliform has decreased. The concentration of water quality parameters was increased like BOD, phosphate, and total coliform that causing polluted water. The concentration of TSS, BOD, COD, phosphates, detergents, oils and fats, fecal coliform, and total coliform exceeds the threshold of water quality standards class II.
STABILITY ANALYSIS AND FAILURE MECHANISMS OF OPEN PIT ROCK SLOPE
Authors: Azzuhry Yahdi
Published: August 2017

Rock mass in nature tend to be unideal, for it is heterogeneous, anisotropic and has discontinuity. The discontinuity makes anisotropic strength and stress in the rock mass, and also controls the changing of the elastic properties of rock mass. This condition results to disruptions in the rock mass strength balance, and finally drives the slopes to collapse. This study aims to determine the slope failure mechanisms in the area of case study, as well as its variations based on the Rock Mass Rating (RMR), Geological Strength Index (GSI), Slope Mass Rating (SMR), kinematic analysis, numerical analysis and monitoring approach slope movement in a coal mine slope applications. The site investigations were implemented to obtain information about slope collapse. Prior to the collapse, the slope inclination was 38° with of 94 meters height, strike slope of N 245 E and direction of slope surface of 335°. After the collapse, the slope was became 25º; and after the collapse materials were cleared, it was 35º. The discontinuity mapping obtained 5 sets of discontinuities, and the data were developed to obtain the value of RMR. The result of piezometer measurements was that at occurrence of collapse, slope elevation was 44.40m. Displacement value from monitoring SSMR showed that when the slope was collapsing in two stages, the first stage value was 70.61cm (a more critical condition, the value was rounded down to 70cm to the implementation in modelling) and the second stage value was at 124.25cm. The value of RMR89 in this study was greater than the value of GSI and SMR. As for the average value, it was obtained 34.67 for RMR89 value and 29.67 for GSI value, these rocks then can be classified into Poor Rock class number IV. The result of kinematic analysis found that sliding planar failure at dips 36°, and wedge failure at dips 36°, 35° and 34°. Acquisition SMR value obtained at 25, 27, 28 and 29. The SMR values classified the rock mass quality into class number IV, the description of the rock mass was relatively poor, the slope stability was low or unstable and the collapse manifold was planar or wedge failure. The result from the analysis of the model with its criteria obtained was that un-collapse conditions at angle 29°. It is recommended to use 29° angle to repair the slopes, and also recommended for overall high wall slope angle. Type of collapse that occurred on the slope failure mechanisms in all of the analysis that has been done, it is known that the mechanisms involved are complex types (combine of wedge failure, planar failure, and step-path failure) or classified into large scale rock slope failure surface.

Water quality monitoring is prone to encounter error on its recording or measuring process. The monitoring on river water quality not only aims to recognize the water quality dynamic, but also to evaluate the data to create river management policy and water pollution in order to maintain the continuity of human health/sanitation requirement, and biodiversity preservation. Evaluation on water quality monitoring needs to be started by identifying the important water quality parameter. This research objected to identify the significant parameters by using two transformation/standardization methods on water quality data, which are the river Water Quality Index, WQI (Indeks Kualitas Air, Sungai, IKAs) transformation/standardization method and transformation/standardization method with mean 0 and variance 1; so that the variability of water quality parameters could be aggregated with one another. Both of the methods were applied on the water quality monitoring data which its validity and reliability have been tested. The PCA, Principal Component Analysis (Analisa Komponen Utama, AKU), with the help of Scilab software, has been used to process the secondary data on water quality parameters of Gadjah Wong river in 2004-2013, with its validity and reliability has been tested. The Scilab result was cross examined with the result from the Excel-based Biplot Add In software. The research result showed that only 18 from total 35 water quality parameters that have passable data quality. The two transformation/standardization data methods gave different significant parameter type and amount result. On the transformation/standardization mean 0 variances 1, there were water quality significant parameter dynamic to mean concentration of each water quality parameters, which are TDS, SO4, EC, TSS, NO3N, COD, BOD5, Grease Oil and NH3N. On the river WQI transformation/standardization, the water quality significant parameter showed the level of Gadjah Wong River pollution, which are EC, DO, BOD5, COD, NH3N, Fecal Coliform, and Total Coliform. These seven parameters is the minimal amount of water quality parameters that has to be consistently measured on predetermined time and location, and also become the indicator of human health and environment health quality. The result of Scilab multivariate analysis was not different with the result from Biplot Add In multivariate analysis, in which the results of water quality significant parameter has been verified with bio-monitoring.

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan zeolit alam termodifikasi sebagai media imobilisasi terhadap dekomposisi material organik pada proses anaerobic digestion. Modifikasi yang dilakukan adalah dengan cara mengimpregnasi ion besi(Fe2+)ke dalam zeolit yang telah dibentuk menjadi cincin Raschig. Impregnasi yang dilakukan adalah impregnasi basah. Dalam penelitian ini digunakan 3 variasi konsentrasi larutan Fe2+ yaitu 10 mg/L; 100 mg/L dan 2000 mg/L. Dari hasil impregnasi zeolit menggunakan ketiga konsentrasi tersebut diperoleh kadar Fe2+ yang terdeposit ke dalam zeolit berturut-turut: 0,0016 mgFe2+/gZeo; 0,0156 mgFe2+/gZeo; 0,3125 mgFe2+/gZeo dan 0 mgFe2+/gZeo digunakan sebagai kontrol. Zeolit termodifikasi Fe2+ kemudian ditambahkan ke dalam reaktor anaerobik yang dijalankan secara batch. Perbandingan volume media zeolit dan cairan adalah 1:1. Substrat yang digunakan berupa campuran limbah distillery spent wash dengan konsentrasi soluble Chemical Oxygen Demand (sCOD) 10.000 mg/L dan keluaran dari digester aktif kotoran sapi sebagai inokulum. Perbandingan volume distillery spent wash terhadap inokulum sebesar 2:1. Proses anaerobik dijalankan selama 28 hari.Jika dibandingkan dengan data Total Solid (TS) dan Volatile Solid (VS), hasil percobaan menunjukkan bahwa data analisis sCOD memberikan data yang lebih akurat dan konklusif untuk mengukur perubahan material organik dalam proses peruraian anaerobik menggunakan media imobilisasi. Dari keempat variasi kadar Fe2+ yang digunakan dalam penelitian ini, Fe2+ dengan kadar 0,0156 mgFe/gZeo memberikan efisiensi penurunan material organik (sCOD) tertinggi yaitu 66,73%. Sedangkan Fe2+ dengan kadar 0,3125 mgFe/gZeo mampu meningkatkan produksi biogas sebesar 43%. Namun secara keseluruhan proses peruraian anaerobik yang menggunakan zeolit termodifikasi Fe2+ menghasilkan biogas lebih banyak daripada kontrol (zeolit tanpa Fe2+).

Security has been a concern since the early days of computing, when a computer was isolated in a room and a threat could be posed only by malicious insiders. To support authorized Data Deduplication in cloud computing ,encryption is enhanced before outsource. Data Deduplication helps to store identical copy of data in Cloud Storage and that consumption is low bandwidth. Third Party control generates a spectrum of concerns caused by the lack of transparency and limited user control .For example , a cloud provider may subcontract some resources from a third party whose level of trust is questionable. There are examples when subcontractors fails to maintain the customer data. There are also examples when third party was not a subcontractor but a hardware supplier and the loss of data was caused by poor –quality storage devices[12].To overcome the problem of integrity and security, this paper makes the first attempt that applying Data Coloring, Watermarking techniques on shared data objects. Then applying Merkle Hash Tree[11],make tighten access control for sensitive data in both private and public clouds.

OBJECTIVE

Adherence to physical activity (PA) recommendations is hampered by the lack of effective strategies to promote behavior change. The Italian Diabetes and Exercise Study 2 (IDES_2) is a randomized controlled trial evaluating a novel behavioral intervention strategy for increasing PA and decreasing sedentary time (SED-time) in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

The study randomized 300 physically inactive and sedentary patients with type 2 diabetes 1:1 to receive theoretical and practical counseling once yearly for 3 years (intervention group [INT]) or standard care (control group [CON]). Here, we report the 4-month effects on objectively (accelerometer) measured daily light-intensity PA (LPA), moderate-to-vigorous–intensity PA (MVPA), and SED-time, and cardiovascular risk factors.

RESULTS

LPA and MVPA both increased, and SED-time decreased in both groups, although changes were significantly more marked in INT participants (approximately twofold for LPA and SED-time and approximately sixfold for MVPA). A significant reduction in HbA1c was observed only in INT subjects. An increase in LPA >0.92 h · day−1 and in MVPA >7.33 min · day−1 and a decrease in SED-time >1.05 h · day−1 were associated with an average decrease in HbA1c of ∼1% and also with significant improvements in fasting glucose, body weight, waist circumference, and hs-CRP. Changes in PA and SED-time were independent predictors of improvements in HbA1c.

CONCLUSIONS

This behavioral intervention is effective in the short term for increasing LPA and MVPA and reducing SED-time. Significant improvements in cardiometabolic risk profiles were observed in subjects experiencing the most pronounced changes in PA and SED-time, even if below the recommended level.

Abstraksi  Jumlah mahasiswa yang mengalami stres meningkat setiap semester. Respon stres dari setiap mahasiswa berbeda, Respon tersebut tergantung pada kondisi kesehatan, kepribadian, pengalaman sebelumnya terhadap stres, mekanisme koping, jenis kelamin dan usia, besarnya stresor, dan kemampuan pengelolaan emosi dari masing-masing individu. Tujuan dari penelitian ini adalah untuk mengetahui pola stres pada mahasiswa praktikum di Fakultas Psikologi Universitas Muhammadiyah Surakarta. Penelitian ini menggunakan metode penelitian kualitatif deskriptif. Subjek penelitian berjumlah 75 mahasiswa yang sedang mengambil mata kuliah praktikum di Fakultas Psikologi Universitas Muhammadiyah Surakarta. Data penelitian diperoleh dengan menggunakan dokumentasi, pengukuran tekanan darah, dan skala stres. Teknik pengumpulan data diperoleh dengan simple random sampling. Analisis data pada penelitian ini menggunakan statistik deskriptif. Secara umum pola stres diawali karena adanya aktivitas fisik yang berlebihan pada mahasiswa praktikum. Hal ini membuat mahasiswa merasa kelelahan dan tegang sehingga tubuh meresponnya dengan timbulnya stres. Mahasiswa awal yang mengambil mata kuliah praktikum yaitu berusia 18–20 tahun lebih rentan terkena stres dibandingkan dengan mahasiswa akhir praktikum yang berusia 21–24 tahun. Sedangkan berdasarkan jenis kelamin, mahasiswa praktikum perempuan lebih rentan mengalami stres daripada mahasiswa praktikum laki – laki. Kemudian pada mahasiswa praktikum dengan stres berat lebih berpotensi memiliki tekanan darah lebih tinggi dari pada mahasiswa praktikum yang memiliki stres sedang dan ringan. Kata Kunci: Pola Stres, Usia, Jenis Kelamin, Tekanan Darah, Mahasiswa Praktikum
