Noise exposure monitoring is essential to assess noise exposure circumstances and provide a noise control plan to minimize noise exposure problems in the workplace. In Malaysia, occupational noise exposure problems have been increasing, especially in the construction industry. Hence, this study aims to investigate the noise exposure problem in a construction casting yard in Malaysia. The objectives of the study were to measure the current occupational noise exposure problem and to propose a noise control action. Field measurement was carried out at a segmented box girder casting yard under the Mass Rapid Transit (MRT) construction project in Selangor, Malaysia. A total of six case studies from four different construction trades had been conducted. This study plotted noise maps and measured personal noise exposure levels for the three construction trades. The results showed that the equivalent sound level exceeded the action level of 85 dBA for these trades. Besides, the bar cutting trade with an 8-hour time-weighted average of 92.3 dBA exceeded the permissible exposure limit of 90 dBA. The noise reduction rating of the hearing protection device was evaluated, and appropriate noise control action was proposed. The proposed noise reduction rating was 32 dBA, so it is expected to reduce the time-weighted average sound level below 80 dBA for this workplace. In conclusion, the results could disseminate to construction workers to raise their risk awareness regarding the noise exposure issue in the workplace. The noise mapping information could also be used for the design of the engineering control to reduce the noise exposure level in the construction workplace.

Fuzzy logic is a moderately new method for tackling building control issues. This method is regularly used to execute frameworks beginning from simple, small or even inserted up to monster. Fuzzy set hypothesis has been usual model frameworks that are challenging to diagram precisely. As a system, fuzzy set hypothesis joins imprecision and subjectivity into the model definition and arrangement prepare. Probabilistic techniques are being utilized progressively in development building. However, when a parameter is communicated in phonetic as opposed to numerical terms, traditional likelihood hypothesis neglects to consolidate the data. The etymological factors can be converted into scientific measures utilizing fuzzy set and framework hypothesis. A development administration issue i.e., estimation of term of an action, is unrevealed utilizing this hypothesis. The proposed procedure is not touchy to little varieties in the participation values. This is an extremely alluring property. In any case, the strategy is delicate to the decision of the fuzzy relations. The instability in the fuzzy relations can be demonstrated alongside different wellsprings of vulnerability. The mean and difference of the parameters required in the issue under thought are evaluated here utilizing another technique. The strategy boosts the result of the whole of the enrolment relationship for a specific recurrence of event and the comparing recurrence of event. One of the primary favorable circumstances of the proposed method is that it can be effortlessly actualized in existing PC programs for venture planning. In Green building planning viewpoints, material choice assumes a significant part in accomplishing the building guidelines; it is possible that it might be of green or non-green materials. Keeping in mind the end goal to accomplish perspective consummately, essential Fuzzy logic approach is to be actualized in order to choose the best option among different accessible materials. This should be possible by dispensing the essential enrolment values based upon the past encounters and positioning them in a request in view of our development necessities all the while. By utilizing this approach, we can likely choose the best material in view of both subjective and quantitative perspective.

Blood sugar in the body is called glucose and it is important that the amount of sugar in the blood is fairly maintained. The body has sugar and blood that is used to store energy in the body. Low or high blood sugar is dangerous to life if it is not treated. The fasting blood glucose level in the morning ranges between 70 mg/dL to 110 mg/dL, after the meal the blood glucose should be less than 140 mg/dL. This paper proposes a method that is best suited to detect blood glucose in the human body and avoid serious health issues by sending a message instantly to the respective number of the patient. Currently, in market Blood Glucose Monitoring (BGM) techniques are vigorous and painful as the blood sample is pricked from the finger that leads to the risk of infection, the strips that were being used were also costly. The solution to this problem statement is a design of non-invasive smart equipment for observing the blood glucose level. One non-invasive method is Red Laser (RL) BGM technique, that is very superior to the other invasive method and non-invasive techniques. Here the refractive index of the laser light is analyzed to determine the blood glucose level. Several tests and experimental results are generated to prove the proposed method is highly accurate.

Sepsis is a global cause of the death due to infection and subsequent overreaction of the immune system. Mortality rates are highest in developed and developing countries in cases of septic shock. Sepsis is a clinical condition with an emergency referral that can be avoided by advance warning. SIRS is a normal immune response to any infection, and hospitals or antibiotics are not required by most people. Early sepsis prediction is possibly life-saving, and we are planning to predict sepsis 6 hours before clinical sepsis diagnosis. We used two types of Standard Scalar and Min Max Scalar pre-treatment methods to pre-treat the data. The Recursive Feature Elimination (RFE) method is used to pick the features most closely related to the predictive or efficiency factor. The ML algorithms used are the Logistic Regression algorithm and XGboost. Cross-validation 10 times with the train splitting method is used to validate attributes. we selected the best model from these two trained models.

Security is imperative to individuals' key opportunity. In the course of recent decades with the headway of correspondence innovation the utilization of web has developed amazingly to trade data with no separation bearer. The most recent drama covers the threats against our technology infrastructures. The most challenging issue in the military network is that secure retrieval of confidential data. Information installing is the way toward implanting data in an information source without changing its perceptual quality. Stenography is the method of thrashing a document, message, picture or video surrounded by another record, message, picture or video. In previous methods, usage of image and text as key produces low security and reversible data hiding as algorithm produces less compression ratio. In our paper we proposed a novel method for increasing the video security by using One Time Password (OTP) and voice key as password and improving compression rate by using Blind detection algorithm. The uses of blind detection algorithm includes greater computational accuracy, high flexibility and deliver faster execution by an estimated high PSNR value .In addition, this paper also includes compressing image, audio and video files and embedding into a single video.

Authors: Heiserman Sam , Zaychik Kirill , Miller Timothy
Published: June 2020

This study presents a novel biometric approach to identify operators, given only streams of their control movements within a manual control task setting. In the present task subjects control a simulated, remotely operated robotic arm, attempting to dock onto a satellite in orbit. The proposed methodology utilizes the Hierarchical Temporal Memory (HTM) algorithm to distinguish operators by their unique control behaviors. Results presented compare the identification performance of HTM with Dynamic Time Warping (DTW) and Edit Distance on Real Sequences (EDR), in both static and real-time data settings. The HTM method outperformed both DTW and EDR in the real- time setting, and matched DTW in the static setting. Observed superior performance of the HTM algorithm lays the foundation for the extension of the proposed methodology to other motion- monitoring applications, such as real-time workload assessment, motion/simulator sickness onset or distraction detection.

On the meaning and novelty of impressionistic thinking on the example of Russian animalistic sculpture of the late XIX – early XX centuries
Authors: Portnova Irina
Published: June 2020

This article dwells on consideration of Russian animalistic sculpture of the late XIX – early XX centuries, representing a new plastic thinking and figurative system. This important historical period, that was marked by the development of Russian impressionism in sculpture, had a fruitful effect on animalistic plastics. By this time, the animalistic sculptural genre, which had fully established itself in its stylistic figurative system, at the turn of the century had experienced something new. We are talking about fresh way o thinking and look as at the plastic itself as at the object of the image. Sculpture has never been of such a «dynamic» quality and the animal image in sculpture has never been perceived so fleetingly before. ЗHere is a figurative concept that encompasses all the fine lines of the semantic significance of animalistic plastics. It is characterized, first of all, by the fact that the image begins to acquire greater symbolic ambiguity and meaningful subtlety. The main purpose of this article is to пTo track the meaning and the novelty of impressionistic thinking in animalistics by the example of the works of A. Golubkina, P. Trubetskoy, N. Andreev, V. Domogatsky. It’s noted that the novelty of the impressionistic thinking in animal sculpture is based on a «movable» plastic and «metamorphoses» impressionistic thinking in animal sculpture is based on “movable” plastic and “metamorphoses” of the sculpture shape and the process, which takes place in animalistics, reflects a significant side of the development of Russian sculpture of the late XIX – early XX centuries, opening up new perspectives and solutions.
JAK2 V617F as a Marker for Long-Term Disease Progression and Mortality in Polycythemia Vera and its Role in Economic Modeling
Authors: Hjelmgren Jonas , Nilsson Kristoffer , Birgegard Gunnar
Published: June 2020

Background: In order to facilitate sound economic evaluations of novel treatments, health-economic models of polycythemia vera (PV) must combine effects on surrogate endpoints in trials with disease progression (DP) and mortality in long-term cohort data. Objective: We validate an economic model for PV that uses Janus Kinase 2 (JAK2) burden as a surrogate endpoint to predict DP (thrombosis, myelofibrosis, and acute leukemia) and overall survival (OS) based on progression-specific mortality. Methods: Long-term observational studies that include information about baseline JAK2 burden were identified via PubMed searches and used to validate the model. Kaplan-Meier (KM) OS curves were extracted using a digitizing software. External validity of the model was analyzed by visually comparing OS curves of the model with the KM curves of the included studies, as well as calculating differences in mean OS estimated as area under the curve (AUC). Results: The model’s predictions of cumulative DP were somewhat lower than the published studies. Over 20 years’ time, our base case model predicted a mean OS for a PV patient (15.0–16.5 years), which was in line with the published studies (15.8–17.5 years). Modeled mean OS was almost two years longer (1.6–1.9 years) for patients with JAK2 <50% than patients with JAK2 ≥50%. Only three long-term observational studies that satisfied the predefined criteria were found and could be used in the validation, but these studies did not capture JAK2 evolution over time. Improved model predictions of DP and mortality based on the longitudinal evolution of JAK2 could be derived from real-world data sources. Such data are currently scarce and future observational studies should be designed to capture the long-term impact of JAK2 on DP and mortality in PV. Conclusions: Our model, based on JAK2 burden as a marker for DP, generated OS estimations that are in line with results of published data.

Few years ago, food combining a popular weight reducing diet has been promoted and practiced by the public in Indonesia. The objective of this study was to compare the effect of food combining on change in body weight with a calorie reducing diet. We used a crossover experiment study design where 12 healthy free-living subjects (10 women, 2 men), age range 18-21 years old and BMI > 25 kg/m2 were randomly allocated into each groups. Participants were prescribed two diets for 3 consecutive weeks with a 6 week washout period when subjects were instructed free to eat. Diet of 1200 kcal/day for women and 1500 kcal/day for men were prescribed for respondents, whereas the food combining intervention included fruits in the morning and a combination of protein foods with vegetables or carbohydrate foods and vegetables for the other meals. The body weight and nutrients intake were measured before and after each intervention. The result analyzed using a linear mixed model and it showed there was no significant difference (p=0.235) in change in body weight after treatment with the food combining (65.8 kg, CI 95%: 59.7, 71.8) as compared to the calorie restricted diet (66.5 kg, CI: 95%: 60.4, 72.5) at F (1, 10) =1.59. The risk inadequate intake of protein, vitamin B-2, folate, calcium, iron and zinc after followed food combining compared to calorie restricted diet should taking into consideration. The food combining as well as energy reducing diet showed a similar effect on reduction in body weight.

Authors: Oladeji Seye Julius , Kayejo Gbenga Victor
Published: June 2020

Urinary tract infections (UTIs) are among the most common human infections with the distribution of etiological agents and antibiotic resistance patterns varying from region to region and from time to time. The aims of this study were to ascertain the prevalence and antibiotic resistance profiles of common Gram-negative uropathogens among patients attending a Tertiary Care Hospital in Ekiti State, Nigeria. One hundred and fifty clean-catch midstream urine specimens were obtained and cultured within 2 hours of collection for the detection of Gram-negative uropathogens. The isolated organisms were identified by standard microbiological methods. Of the total 150 urine specimens analyzed, 82 (54.67%) specimens were positive for Gram-negative uropathogen with significant bacteriuria of which 34 (41.46%) were males and 48 (58.54%) were females. Klebsiella spp. 38 (46.34%) and Escherichia coli 32 (39.02%) were the most frequently isolated Gram-negative uropathogens, followed by Proteus mirabilis 10 (12.20%) while the least occurring uropathogen was observed to be Pseudomonas aeruginosa 2 (2.44%). All the isolated uropathogens were observed to be highly resistant to the commonly prescribed antibiotics. Emerging resistance to carbapenems was also observed. Nevertheless, carbapenems showed highest susceptibility compared to other tested antibiotics. Conclusively, high levels of resistance of uropathogens to antibiotics exist in our setting. This therefore calls for continuous antibiotic surveillance and improved antibiotic stewardship.

Authors: Dr. Thadei Kiwango
Published: June 2020

This paper is a determination of use of digital technology for instructional purposes in out of school environment. The paper specifically explores the awareness of primary school pupils on the significance of using computers, access to computers and the ability to use computers. A total of 458 pupils were selected from 9 primary schools in three (3) divisions of Meru District in Arusha Region. The findings of the study shows that only 18.8% of pupils were aware of the usefulness of computers, while even smaller percentage of pupils (9.6%) had computers at home. On the other hand, only 16.6% of pupils could use computers. On the basis of the findings, it could be inferred that although some pupils are aware that computers can potentially facilitate learning, they are not adequately available at home, while also quite few pupils can use them. On the basis of these observations; the government, school administrators and other stakeholders in education should work together to raise pupils’ awareness of the usefulness of computers, along with making computers available and enabling pupils to make use of them to improve learning both in regular classroom and out of school time. At the bottom line, studies that are geared towards exploring the robust approaches which not only can raise pupils’ awareness but can more importantly make families see the importance of availing computers to their school children while at the same time encouraging pupils to use computers to improve their learning at school and out of school time are inevitable.

Published: June 2020

According to the World Bank, it is estimated that more than 2 million adults, on the planet, do not have an account to transact, more than 200 million micro, small and medium enterprises lack businesses. According to Global Findex in Ecuador, approximately, 46.2% of the Ecuadorian population over 15 years of age had an account in a formal financial institution in 2014. The objective of this study is the financial inclusion in the Ecuadorian private banking system based on sustainability reports of the year 2016. In the research, a methodology of documentary and descriptive research was used for the elaboration of the theoretical framework, while for the empirical study the methodological scheme of the transversal-type phenology was used and 4 financial institutions. The analyzed financial institutions present an instrumentalist approach to corporate social responsibility. The evidence suggests that, starting with the 2008 Constitution, a regulatory and institutional environment for financial inclusion has been formed. Finally, during 2016 there was an improvement in the use and access to financial products and services.
El desempeño reciente del sector agrario pampeno: sus potencialidades y perspectivas. análisis de las explicaciones económicas
Authors: Dileo Estefanía Soledad
Published: June 2020

La inserción de Argentina como país exportador de productos primarios y manufacturas de origen agrario explica la importancia de la producción agrícola en el proceso de acumulación nacional. En línea con esto, la ciencia económica, desde distintas concepciones, se ha abocado al estudio de dicho sector para conocer sus potencialidades para impulsar el crecimiento y el desarrollo de la economía argentina. Como resultado de esto, al aproximarse a la literatura especializada, se encuentra una multiplicidad de enfoques económicos que explican y analizan el sector agrario pampeano desde distintas perspectivas. Desde nuestro punto de vista, el disenso que se verifica en la literatura sobre el sector, guarda relación con la forma en la cual la ciencia económica aborda los fenómenos que constituyen su objeto de estudio. La propuesta del presente trabajo consiste en realizar un análisis documental de las distintas explicaciones sobre el desempeño reciente del sector agrario pampeano –específicamente, el boom sojero-, estructurándolo de tal forma de poner de manifiesto la manera en que abordan lo que pretenden explicar. El resultado del análisis no sólo logra poner de relieve la correspondencia entre las formas de conocer de las explicaciones agrarias y los postulados epistemológicos de la ciencia económica, sino que también aquello en lo que se sustenta la falta de consenso entre los especialistas para explicar el sector agrario pampeano.

Authors: Garza Rosario , Martínez Edith
Published: June 2020

The successful performance of the production organizations of material goods or service necessarily involves the correct location of the elements that make up the productive system, so as to satisfactorily respond not only to current situations but also to possible future scenarios. Among the techniques of Operations Research, which are useful for analyzing the behavior of systems, there is Simulation, which has demonstrated its advantages in the quantification of output variables or indicators of interest, associated with each designed scenario. In particular, this article demonstrates the convenience of using Simulation to evaluate the layout of an organization in different scenarios and multiple criteria. The steps of a hybrid approach based on Simulation and Multicriteria techniques and their application to two case studies are shown. To evaluate the behavior of the systems according to the designed layout, respective models of Simulation are generated and solved through the ARENA language version 15.0. In addition, as multi-attribute techniques for the selection of the preferred layout the following methods are applied: lexicographic and EDIPO; in the latter case with the use of the DECISION software.

Economic sensor for Misiones province from 2005 to 2018
Authors: Álvarez Nicolás , Heredia Juan Luis , León María Natalia
Published: June 2020

This paper presents the construction of a composite indicator of economic activity for the province of Misiones for the period 2005 – 2018, in order to measure fluctuations of economic and growth cycles. The methodologies proposed by The Conference Board (2001) and Jorrat (2003), that are referents at international and national levels respectively, are used. This methodology gives less weight to time series which variations have more volatility. After selecting eleven component series from public sources of information and representatives from different sectors of the provincial economic activity, seasonally adjusted using X-13 ARIMA and aggregating them, it is obtained a composite indicator representative for the economic activity, named Misiones Economic Sensor (MisES). This indicator is a first approximation of provincial economic activity’s fluctuations, and given that cross correlation with EMAE (Mensual Estimator of Economic Activity) is 0.93 when t=0, it is presumed that it is represents fluctuations observed in the provincial economy.

Family businesses are of great importance because they have generated new jobs over the years, allowing them to be the object of study in various investigations; despite this, no emphasis has been placed on case studies that highlight both leadership and the decisive process in this type of organizations, known as succession. As a result, concern was generated to study a company that has gone through this process, where the main purpose is to show the ability to solve problems, challenges and how to cope with succession, in addition to knowing whether leadership is a key factor in it, deepening it to a greater extent in a case study, with semi-structured interview guides. After analyzing and interpreting what the informants mention, it is obtained as a result that leadership was a fundamental piece in this process, with an autocratic leadership that was exercised by the founder of the company. Currently, the new owner has used different types of leaderships depending on the situation, called situational. It is recommended to continue with that leadership style that characterizes him and to continue to be successful as a recognized family business.

To this end, cabinet work was carried out in two parts: The first was a review and analysis of the Guidelines and Criteria for the Definition, Identification and Measurement of Poverty that appear in the Official Gazette of the Federation; and the second in the analysis of the data on deprivation and income that the National Council for the Evaluation of Social Development Policy (CONEVAL) and the National Institute of Statistics, Geography and Informatics (INEGI) offer for 2010 2015 and 2010, 2012 , 2014 and 2016, respectively. Among the most important results, it can be mentioned that, in effect, the average shortfalls of the househo in Quintana Roo decreased, however, the income in 2016 remained in conditions similar to those of 2010, that is, the reduction of extreme poverty can be attribute only to state intervention through the creation of infrastructure and not the effectiveness of its economic policies.
