Authors: Gao Bingwei , Ye Yongtai , Han Guihua
Published: August 2019

Background:

Hydraulic quadruped robot is a representative of the redundant transmission.
This is a great challenge for multi-joints coordinated movement of the robot, because of the
movement coupling with several freedom degrees among kinematic chains. Therefore, there is an
urgent need to realize the decoupling among the joints of the hydraulic quadruped robot.

Objective:

The purpose of this study is to provide an overview of controller design from many
studies and patents, and propose a novel controller to realize the decoupling control among joints
of a hydraulic quadruped robot.

Methods:

For the coupling problems between the thigh and calf of a hydraulic quadruped robot,
based on the Lagrangian method, dynamics model of the robot’s leg is established. The influence of
driven system is considered. The model of the hydraulic servo driven system is built, so as to obtain
the coupling relationship between thigh and calf of hydraulic quadruped robot. Based on the multivariable
decoupling theory, a PID neural network decoupling controller is designed.

Results:

The researches on experiments are executed. The PID neural network decoupling control
method is compared with the control that does not use any decoupling method. The decoupling effect
of the proposed algorithm is verified on the thigh and the calf of the hydraulic quadruped robot.

Conclusion:

The designed PID neural network decoupling control method reduces the crosscoupling
between thigh and calf of the hydraulic quadruped robot, and has obvious effect to improve
the dynamic characteristics of single joint of robot's leg.
Chaos-Based Controlled System Using Discrete Map
Authors: Das Anup Kumar , Mandal Mrinal Kanti
Published: August 2019

Background:

The design of efficient and fast controller for controlling the process parameter
is always a challenging work to the control system designer. The main objective of this article
is to design a secure chaos based controller by synchronizing two chaotic systems. The initial
values of the chaotic systems are considered as the set value and initial process value of the physical
parameter to be controlled.

Methods:

The proposed design of the controlled is done by synchronizing two-dimensional chaotic
Henon map through nonlinear control method. One map is taken as a driver system and its initial
value is considered as the set value of a specific process of a given system. On the other hand, another
identical map is taken as the driven system and its initial value is the initial process value of
the given process control system. Both the chaotic map become synchronized via nonlinear control
law. The accumulation of error until synchronization is achieved which is converted into a suitable
signal to operate the final control element to enhance or decrease the initial process value towards
the set value. This self-repetitive process will achieve the control of the process parameter.

Results:

In experiment we have observer that the error signal becomes zero after a small time interval
(in simulation it takes only few iteration) and the accumulated error remain fixed in a steady
value. This error is responsible to maintain the process value to the set value. The entire process has
been implemented in hardware environment by using microcontroller ATMEGA 16 and also in the
Proteus simulation software.

Conclusion:

The controller is very fast because the algorithm of nonlinear control law for synchronization
is very fast. Since the controller is designed in chaotic regime so it is secure.

Локализация возбуждений вблизи тонкого дефектного слоя с нелинейными свойствами, разделяющего линейный и нелинейный кристаллы
Authors: Савотченко С.Е.
Published: August 2019

It is shown that the localized and quasi-local stationary states exist near a thin defect layer with nonlinear properties separating a linear medium from a non-linear medium of Kerr type. Localized states are characterized by a monotonically decreasing field amplitude on both sides of the interface. Quasi-local states are described by a field in the form of a standing wave in a linear medium and monotonously decreasing in a nonlinear medium. The contacts with nonlinear self-focusing and defocusing media are analyzed. The mathematical formulation of the proposed model is a system of linear and nonlinear Schrödinger equations with a potential that is nonlinear with respect to the field and which simulates a thin defect layer with nonlinear properties. Dispersion relations determining the energy of local and quasi-local states are obtained. The expressions for energies were obtained explicitly in limiting cases and the conditions for their existence were indicated.

Published: August 2019

The results of complex X-ray and ultraviolet (UV) nanosecond laser radiations action on alkali-containing silicate glasses is presented.It is shown that under the action of X-ray radiation color centers with luminescent properties appear in glasses. This is caused by the increase of concentration of glass network structural defects. Under the action of laser radiation the destruction of these defects takes place, accompanied by the bleaching of glass and by the disappearance of luminescence. The dynamic of glass bleaching under the laser action and the influence of alkali metals ions (Li, Na, K) on this precess is studied. The mechanisms of color centers destruction by laser radiation are proposed..
Динамика оптических и физиологических свойств кожи человека in vivo в процессе ее компрессии
Authors: Зюрюкина О.А. , Синичкин Ю.П.
Published: August 2019

The results of the study of dynamics of the optical and physiological properties of the human skin in vivo when applying and removing external mechanical compression based on the analysis of temporal changes in the diffuse reflectance spectra of human skin in the range of 400–2000 nm are presented. In the spectrum range 500–600 nm (hemoglobin absorption areas), the temporal dynamics of the skin reflectance coefficients show that skin compression leads to an exponential decrease in the blood content in the skin, while the average time for displacing blood from the compression region is about 4–5 min. After the compression is relieved, the blood filling of the skin is restored exponentially during a time of about 30 s. In the spectral range 700–2000 nm, the peculiarity of the skin reflectance coefficients after skin compression is applied is their monotonic decrease according to a two-exponential law with characteristic times of the order of 10 s and several minutes, which can be caused by the displacement of free and bound water from the compression region.

Authors: Han Min Kyu , Cho Belong , Kwon Hyuktae , Son Ki Young , Lee Hyejin , Lee Joo Kyung , Park Jinho
Published: August 2019

Background

There is a growing interest in mobile technology for obesity management. Despite the known effectiveness of workplace-based weight loss programs, there are few studies on mobile phone–delivered interventions.

Objective

This study aimed to develop and verify an integrated and personalized mobile technology–based weight control program, named Health-On, optimized for workplaces.

Methods

A weight reduction algorithm was developed for calorie prescription, continuous monitoring, periodic feedback and reevaluation, goal resetting, and offline intervention with behavior-changing strategies. A total of 30 obese volunteers (body mass index ≥25 kg/m2) participated in the 12-week Health-On pilot program. The primary outcome was weight reduction, and secondary outcomes were improved anthropometric measures, metabolic profiles, and fat computed tomography measures, all assessed pre- and postintervention.

Results

Health-On incorporated proprietary algorithms and several strategies intended to maximize adherence, using compatible online and offline interventions. The mean weight of 30 participants decreased by 5.8%, and median weight also decreased from 81.3 kg (interquartile range [IQR] 77.1-87.8) before intervention to 76.6 kg (IQR 70.8-79.5) after the 12-week intervention period (P<.001). The metabolic profiles and fat measures (blood pressure, glycosylated hemoglobin, total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, alanine aminotransferase, and visceral and subcutaneous adipose tissue; P<.05) also improved significantly.

Conclusions

In this single-group evaluation of 30 participants before and after the Health-On program, body weight decreased and metabolic profiles and fat measures improved. Follow-up studies are needed to assess effectiveness and long-term adherence.

Authors: Keim Sabine , von Au Alexandra , Matthies Lina Maria , Wallwiener Stephanie , Brugger Sarah , Reisenauer Christl , Wallwiener Markus
Published: August 2019

BACKGROUND

Background: Many women experience urinary incontinence (UI) during andafter pregnancy due to pelvic floor weakness. First-line therapy is conservative treatment, which nowadays can be facilitated by using digitalsolutions.

OBJECTIVE

The aim ofthe present study was to investigate the efficacy and effectiveness of pelvinain patients with existing UI.

METHODS

Methods: In the present observational study we analyzed the effectivenessof pelvina, a certified digital pelvic floor training course, in reducing UI symptoms by regularly applying “The Questionnaire for Urinary Incontinence Diagnosis” (QUID) and furthermore examining quality of life (QoL) by conducting the SF-6D.

RESULTS

Results: In this prospective study, 373 patients with a median age of 36 years (IQR 33 - 47 years) were included. At baseline the patients had a median QUID of 11 (IQR 11 - 15). During the course, incontinence improved significantly to a QUID of 5 (IQR 2 – 11; p<0.001). Additionally, the patients had also shown a significant impairment in their QoL at baseline with a value of 19 (IQR 16 - 22) in SF-6D. After completing the course, the QoL had risen to 24 (IQR 20 - 26).

CONCLUSIONS

Conclusion: Use of the certified digital pelvic floor course pelvinasignificantly reduces existing UI due to pelvic floor weakness over the timespan of the course. At the same time QoL is significantly improved.

Promoting Antenatal Care Attendance Through a Text Messaging Intervention in Samoa: Quasi-Experimental Study (Preprint)
Authors: Watterson Jessica L , Castaneda Diego , Catalani Caricia
Published: August 2019

BACKGROUND

Antenatal care (ANC) has the potential to improve maternal health, but it remains underutilized and unevenly implemented in many low- and middle-income countries. Increasingly, text messaging programs for pregnant women show evidence that they can improve the utilization of ANC during pregnancy; however, gaps remain regarding how implementation affects outcomes.

OBJECTIVE

This study aimed to assess facilitators and barriers to implementation of an SMS text messaging intervention for pregnant women in Samoa and to assess its impact on ANC attendance.

METHODS

This study took place in Upolu, Samoa, from March to August 2014 and employed a quasi-experimental design. Half (n=3) of the public antenatal clinics on the island offered adult pregnant women the SMS text messaging intervention, with 552 women registering for the messages. At the comparison clinics (n=3), 255 women registered and received usual care. The intervention consisted of unidirectional text messages containing health tips and appointment reminders. The outcome of interest was the number of attended antenatal visits. Implementation data were also collected through a survey of the participating midwives (n=7) and implementation notes. Data analysis included a comparison of women’s baseline characteristics between the two groups, followed by the use of negative binomial regressions to test for associations between participation in the intervention and increased ANC attendance, controlling for individual characteristics and accounting for the clustering of women within clinics.

RESULTS

The comparison of ANC attendance rates found that women receiving the SMS text messaging intervention attended 15% fewer ANC visits than the comparison group (P=.004), controlling for individual characteristics and clustering. Data analysis of the implementation process suggests that barriers to successful implementation include women registering very late in pregnancy, sharing their phone with others, and inconsistent explanation of the intervention to women.

CONCLUSIONS

These results suggest that unidirectional text messages do not encourage, and might even discourage, ANC attendance in Samoa. Interpreted with other evidence in the literature, these results suggest that SMS text messaging interventions are more effective when they facilitate better communication between patients and health workers. This study is an important contribution to our understanding of when SMS text messaging interventions are and are not effective in improving maternal health care utilization.

A B S T R A C TGreen solvent, an environmentally friendly solvent in form of subcritical water (SBCW) and pressurized CO2, has been used as media in process intensification. It has characteristic of having low or even zero toxicity. Hence it can simplify purification procedure. In this communication, development of technology applications of those green solvents, i.e. extraction, particle synthesis, and reaction engineering, is briefly presented. In general, studies show a positive utilization of green solvents of subcritical water and pressurized CO2. For example, in pectin extraction, yield up to 90% has been obtained when the combined solvent was used. In another application, hydrolysis using SBCW-CO2 as combined solvent has facilitated 100% conversion of pinene.Keywords: carbon dioxide; intensification process; subcritical water A B S T R A KGreen solvent, yakni pelarut yang ramah lingkungan dalam bentuk air subkritis (subcritical water, SBCW) dan CO2 bertekanan yang telah dikembangkan untuk media pemrosesan, sebagai salah satu upaya intensifikasi proses.

Drivers in Expressway Superlong Tunnels: The Change Patterns of Visual Features and the Discriminant Model of Driving Safety
Authors: WU Ling , ZHAO Weihua , ZHU Tong , LIU Haoxue
Published: August 2019

A real-vehicle experiment was carried out in the superlong highway tunnel environment to study the change patterns of driver’s visual features, tracked by eye tracking devices, and the discriminant model of driver’s safety status. On the basis of statistical analysis, a single index and a comprehensive index discriminant model, both based on a C4.5 decision tree, were established. The results showed that compared with the non-tunnel highway sections, the driver’s pupil size was larger, and the gaze duration was longer in the tunnel section. Driver’s pupil size was larger in mid-tunnel section than in the entrance section and exit section. Gazes at the exit section were mainly short gazes. Compared to the exit section, driver’s pupil size changed more dramatically in the entrance section, and the gaze duration was longer. The single visual parameter indicator could clearly discriminate the driver’s safety status in the mid-tunnel section and the non-tunnel sections, while the dual-index-based identification model could clearly discriminate the safety status in each highway sections. The study deepens the research on the driver information perception model in superlong highway tunnels. Also, the study provides a theoretical basis for establishing a visual-feature-based real-time safety status discriminant.

The Role of the Hydrographer in Rating Curve Development
Authors: Hamilton Stuart , Watson Marianne , Pike Robin
Published: August 2019

Stage-discharge rating curves are used to produce most of the world’s discharge data. The shape of these curves is dependent on the shape of the channel that controls flow. Changes in rating curves occur over time in response to transitory (e.g., vegetation, ice, debris) or persistent (e.g., aggradation/degradation) changes of the rated channel. Errors in rating curve development can result from the mischaracterization of the shape of the curve at a given time, or the misidentification of patterns of change over time. While data-driven methods for rating curve calibration are desirable, conventional statistical regression techniques, unfortunately, require far more data points to fully characterize the patterns of change in the curve shapes than are commonly available. This article discusses the benefits of field observations of the stream channel in support of rating curve development. The mathematical form of the rating curve can be inferred from observations of natural channel control features that link to principles of flow. In this article, the theoretical components of the rating curve equation are discussed with emphasis on how field observations can be used to groundtruth calibrated values for the coefficient, offset, and exponent for each segment of a stage-discharge rating curve. The article also explains how conceptual models developed by the hydrographer add value to the calibration process.

The maximum efficiency of nano heat engines depends on more than temperature
Authors: Woods Mischa P. , Ng Nelly Huei Ying , Wehner Stephanie
Published: August 2019

Sadi Carnot's theorem regarding the maximum efficiency of heat engines is considered to be of fundamental importance in thermodynamics. This theorem famously states that the maximum efficiency depends only on the temperature of the heat baths used by the engine, but not on the specific structure of baths. Here, we show that when the heat baths are finite in size, and when the engine operates in the quantum nanoregime, a revision to this statement is required. We show that one may still achieve the Carnot efficiency, when certain conditions on the bath structure are satisfied; however if that is not the case, then the maximum achievable efficiency can reduce to a value which is strictly less than Carnot. We derive the maximum efficiency for the case when one of the baths is composed of qubits. Furthermore, we show that the maximum efficiency is determined by either the standard second law of thermodynamics, analogously to the macroscopic case, or by the non increase of the max relative entropy, which is a quantity previously associated with the single shot regime in many quantum protocols. This relative entropic quantity emerges as a consequence of additional constraints, called generalized free energies, that govern thermodynamical transitions in the nanoregime. Our findings imply that in order to maximize efficiency, further considerations in choosing bath Hamiltonians should be made, when explicitly constructing quantum heat engines in the future. This understanding of thermodynamics has implications for nanoscale engineering aiming to construct small thermal machines.
The Mythological Thought of Rigveda
Authors: Jing Cai
Published: August 2019

Mythological thought is a specific way of thinking in the history that human beings transit from the age of barbarism to the age of civilization. It reflects human beings’ divine experience on nature and life as a method for human beings to master and transcend the nature as well as  the interpretation of initial human society beyond humanism, which symbolizes the evolution of human thoughts from primitive thoughts to higher logic thoughts. The thinking mode and emotions of Indians are deeply rooted in religious views, which were even reflected in ancient Vedic period. Rigveda is a paean that was generated when Aryans fought against invasion by different races and the nature. Aryans on the grassland led a nomadic life in the vast world. They felt the spirits of all things due to worship of the nature so they were generous with worship of deities. After Aryans lived a stable life in the agrarian society, the mythological world of Aryans developed from polytheism to monolatry. In other words, it developed towards the world with fewer deities or the lord deity. With polytheism, their worship for deities was gradually improving simultaneously. As the origin of India religious culture, Rigveda has reflected various features of Indian’s mythological thought.
Godan, The Film: What It Replicates and What It Hides
Authors: Ishwarrao Pallavi Taru , Chikhlikar DR. Rajpalsingh
Published: August 2019

The present research paper compares the novel Godan by Munshi Premchand written in 1936 in pre independence era and the film directed by Trilok Jetly in 1962 in post independence era. It simply underlines the scene, plot, persons and events etc. the cinema replicates or hides. Literature and cinema seems to have one similar motif or seems to work on the similar ground that is to reflect society. Literature doesn’t lie but “not mentioning something” or “saying it in different way” also ruins history. Generally we consider literature as a piece of history and what is written in it, we take it as a reality or truth. And if this literature dosent mentions anything we don’t think it ever exit or nothing worthy of considering. But is this the only truth? isn’t there  not a world beyond literature? There is a very big scenario outside the frame of literature, which the so called literary persons forget to mention.  About the cinema also we have the same formation, we think that what it shows reflects reality or is strongly influenced by the reality. And cinema has one big advantage of reaching out to the largest amount of people. It has the tremendous amount of audience compared to literature. It can influence people in a great amount. The adaptation of literary classics to films has surged as one of the most appealing topics in the twenty-first century in interdisciplinary studies. Literature and Cinema both are an inevitable part like the heart of the society. They are known as the mirror which reflects the true and somehow in some extent the actual image of the society. They are always influenced by and to the society. The book Godan, a masterpiece in which the theme of social evil’s is successfully depicted and marvelously knitted around the novel is all about the sensibility of lack of humanity, famine, poverty and exploitation of Indian peasantry.

BAR-Based Multi-dimensional Nonequilibrium Pulling for Indirect Construction of QM/MM Free Energy Landscape: From Semi-Empirical to Ab Initio
Authors: Sun Zhaoxi
Published: August 2019

The indirect method for the construction of Quantum mechanics (QM)/ molecular mechanics (MM) free energy landscapes provides a cheaper alternative of free energy simulations at QM level. The indirect method features a direct calculation of the free energy profile at a relatively cheap low-level Hamiltonian and a low-level to high-level correction. In the thermodynamic cycle, the direct low-level calculation along the physically meaningful reaction coordinate is corrected via the alchemical method, which is often achieved with perturbation-based techniques. Often the indirect method can lead to about an order of magnitude speedup in free energy simulation. In our previous work, a multi-dimensional nonequilibrium pulling framework is proposed for the indirect construction of QM/MM free energy landscapes. The method relies on bidirectional nonequilibrium pulling and bidirectional reweighting with the statistically optimal estimator. In the previous work, we focus on obtaining semi-empirical QM (SQM) results indirectly from direct MM simulations and MM<->SQM corrections. In this work, we apply this method to obtain results under ab initio QM Hamiltonians by combining direct SQM results and SQM<->QM corrections. The indirect nonequilibrium scheme is tested on a dihedral flipping case and a series of SQM and QM Hamiltonians are benchmarked. It is observed that PM6 achieves the best performance among the low-level Hamiltonians, while AM1 and MNDO perform less well. Therefore, we recommend using PM6 as the low-level theory in the indirect free energy simulation. The comparison between the indirect results from different SQM Hamiltonians could also provide some hints on the development of charge models. As AM1 can be corrected with the bond charge correction (BCC) to provide a cheap and accurate charge model, which is able to accurately reproduce the electrostatic potential (ESP) at HF level, PM6 would be able to do the same thing. Considering its higher similarity to the high-level Hamiltonians, the PM6-BCC model could be more accurate than the existing AM1-BCC model. Another central result in the current work is a basic protocol of choosing the strength of restraints and an appropriate time step in nonequilibrium free energy simulation at the stiff spring limit. We provide theoretical derivations to emphasize the importance of using a sufficiently large force constant and choosing an appropriate time step. It is worth noting that a general rule of thumb for choosing the time step, according to our derivation, is that a time step of 1 fs or smaller should be used, as long as the stiff spring approximation is employed, even in simulations with constraints on bonds involving hydrogen atoms.
Fundamentos Metafísicos da Ciência Moderna: Uma análise/Metaphysical Fundaments of Modern Science: An Analysis
Authors: Mulinari Filicio
Published: August 2019

A visão da ciência enquanto um saber puramente objetivo e, por isso, livre de suposições metafísicas, ainda persiste na contemporaneidade, seja no âmbito ordinário do senso comum, seja nos meios científicos universitários. Sob essa perspectiva, percebe-se que há certo olhar que prevalece como uma máxima: a ciência moderna suplantou a metafísica. Noutros termos, ainda hoje se acredita que, após as descobertas da Revolução Científica, com Copérnico, Galileu, Newton, entre outros, o discurso metafísico foi extinto da ciência. Embora essa visão sobre a ciência não seja unânime e, ao contrário, venha cada vez mais sendo solapada no meio acadêmico, não é incomum observar que ela ainda está presente entre os cientistas e teóricos da ciência brasileiros. Assim sendo, o objetivo desse artigo é, primeiramente, mostrar que a ciência  moderna não rejeita – ao menos em princípio – às teses metafísicas, mas sim uma visão metafísica específica, a saber, a oriunda dos escritos de Aristóteles e que sustentou a visão científica anterior à concepção moderna. Além disso, o artigo mostra que, apesar da pretensa objetividade e matematização da ciência, a concepção moderna lança mão de uma visão particular de ontologia/metafísica em seu fundamento. Por fim, pretende-se concluir, por meio de uma análise comparativa da história da ciência, que não só é impensável, como também improvável se imaginar qualquer saber científico sem um alicerce ontológico, i.e., filosófico.Abstract: The vision of science as a knowledge purely objective and therefore free from metaphysical assumptions still persists in contemporary. From this perspective, it is clear that there is a certain look that reigns under a common maxim: modern science has supplanted metaphysics. In other words, today is believed that after the scientific discoveries of the Scientific Revolution Modern, with Copernicus, Galileo, Newton, among others, the metaphysical discourse of science was extinguished. Although this view of science is not unanimous and, instead, come increasingly being undermined, it is not uncommon to observe that it is still present and it is like a vision of the majority of Brazilian scientists. Therefore, the aim of this paper is, firstly, to show that modern science does not reject - at least in principle - the metaphysical thesis, but a metaphysical view specific, namely, deriving from Aristotle's writings. Furthermore, the article shows that despite the alleged objectivity and 'mathematization' of science, the modern design makes use of a particularly modern ontology/metaphysics in its foundation.

Fisicalismo Experimental: A solução de Claude Bernard para um problema da Filosofia da Biologia atual/Experimental Physicalism: Claude Bernard's solution for a problem of current Philosophy of Biology
Authors: Caponi Gustavo
Published: August 2019

A clausura causal do domínio físico pode ser aceita sem por isso negarmos que exista genuíno conhecimento causal, capaz de nos habilitar ao controle experimental dos fenômenos, que não esteja formulado em termos físicos, e que dificilmente possa ser formulado nesses termos. A Biologia dá bons exemplos disso: tal é o caso das explicações que articuladas na base da Teoria da Seleção Natural; mas também é o caso das explicações fisiológicas. Elas, conforme Claude Bernard soube mostrá-lo, podem fornecer efetivo e eficaz conhecimento causal, sem para isso ter que estar construídas em termos físico-químicos.Abstract: The causal closure of the physical domain can be accepted without denying that there exists genuine causal knowledge that can enable us to control experimental phenomena, but is not formulated in physical terms, and that can hardly be formulated in such terms. Biology gives good examples of it: such is the case of explanations articulated by Natural Selection Theory; but it is also the case of physiological explanations. These, as Claude Bernard could show, can provide effective and efficient causal knowledge without been constructed in physico -chemical terms. Keywords: Bernard, Claude; causal explanation; physicalism; reductionism; supervenience.
A “Coerência” em decisões no Direito e na Moral na Teoria da Argumentação de Klaus Günther
Authors: Bresolin Keberson
Published: August 2019

O objetivo principal deste artigo é analisar e problematizar a ideia de coerência (Kohärenz) na teoria da argumentação proposta pelo jus filósofo Klaus Günther. Para isso, será demonstrada a separação realizada por ele entre o discurso de justificação e o discurso de aplicação. O primeiro opera no nível de validade de normas, o qual preza pela consideração de todos os interesses envolvidos, enquanto que o segundo preocupa-se com a consideração das características relevantes de uma situação concreta a fim de encontrar a norma mais bem adequada à situação. A tese defendida aqui é a de que a separação dos discursos consolidam a ideia de democracia e também que a coerência gera uma otimização normativa na aplicação, além de oferecer a ideia de um sistema normativo coerente na moral e no direito.

Nowadays Employees Work Outcomes is the primary concern of academia of higher education. Hence, to understand this perspective the current study has examined the impact of emotional instability on employees work outcomes (Workaholism, Organizational Citizenship Behavior and Burnout). This study also examined the moderating role of compulsory citizenship behavior and transactional and transformational leadership styles. Sample of the study was faculty members of public and private universities. The sample of 400 teachers were selected from public and private universities of different cities of Pakistan. Emotional Instability Scale by John and Srivastave, Organizational Citizenship Behavior Scale by Smith et al, burnout scale by Ayala Malach Pines and Workaholism Battery by Spence and Robbins were used to measure the study variables. Smart PLS (Partial Least Square) was used for hypothesis testing. Finding of the study showed that there was negative and significant relationship between emotional instability, workaholism and organizational citizenship behavior whereas, there was positive and significant relationship between emotional instability and burnout. Further results demonstrated that transactional and transformational leadership play moderating role in relation to emotional instability and workaholism. Nevertheless, this study will provide insight to develop policies to lowers the level of burnout, and will also help administrators to implement such leadership style that decrease emotional instability and raise performance.

pozwalające na wyłączenie pracownika organu.
E-urząd jako odpowiedź na współczesne wyzwania zarządzania publicznego w
Authors: Charzewski Przemyslaw

Administracja publiczna ewoluuje. Od dłuższego czasu obserwujemy postępującą

komputeryzację w życiu publicznym. Poza pewną grupą ludzi, już niemal wszyscy

korzystają z dobroci wsp.łczesnych technologii. Stało się to już tak codzienne, że

zwykły obywatel rzadko wyobraża sobie, że miałby gdziekolwiek stać w kolejce, na

cokolwiek czekać (prawdopodobnie zostałoby to uznane za nieporozumienie). Rosnący

standard życia stał się tym samym impulsem do przeobrażeń zachodzących

w administracji publicznej, kt.ra zwłaszcza na szczeblu samorządowym powinna

pokazywać, że interesuje się obywatelem, czy też m.wiąc szerzej – wsp.lnotą samorządową.

Tym samym administracja publiczna musiała się zaadoptować do nowych

warunk.w, a więc zaakceptować bardziej wyraziście sw.j „służebny” (z przeznaczenia)

względem obywatela charakter. Dodatkowe determinanty wynikają z członkostwa

w Unii Europejskiej, kt.re zobligowało nasz kraj do stopniowego wyr.wnywania

poziomu standard.w usług publicznych do tych, jakie mają w swoich państwach

obywatele innych, lepiej rozwiniętych państw członkowskich.

Published: August 2019

Introdução: Mais de 550 mil casos de tumor de cabeca e pescoco surgem anualmente, e estes constituem a 5. neoplasia mais prevalente no mundo. As neoplasias de cabeca e pescoço tem etiologia multifatorial, onde se destacam como principais agentes pre-oncologicos, segundo a literatura, o tabaco, alcool, HPV, exposicao ao sol e o proprio envelhecimento. As lesões neoplasicas geralmente sao detectadas tardiamente por serem assintomaticas, e em decorrência disso os tumores sao descobertos em uma fase muito avancada, deixando graves sequelas e um baixo indice de sobrevida. Métodos: Aplicaram-se questionarios em 35 pacientes com diagnostico de tumor de cabeca e pescoco, e em 35 pacientes sem neoplasias diagnosticadas. O questionario avaliou os fatores pre-oncogenicos de cada grupo. Resultados: Observou-se dentre os pacientes com neoplasia: 71,4% sendo do sexo masculino; 94,3% caucasianos; 77,1% tendo historico de cancer na familia; 73,5% ja fizeram uso de tabaco; 37,1% foram etilistas e 86,7% tiveram um alto indice de radiacao solar. Ja no grupo de pacientes sem neoplasias, foi observado: 45,7% sendo do sexo masculino; 82,9% caucasianos; 65,7% tendo historico de cancer na familia; 39,3% fizeram uso de tabaco; 8,6% foram etilistas e 44,1% tiveram um alto indice de radiacao solar. Conclusão: Mediante o que foi pesquisado, pode-se afirmar que a maioria dos pacientes com neoplasias possuiam fatores pre-oncogenicos elevados. Ja no grupo sem neoplasias diagnosticadas, encontrou-se um indice menor durante a pesquisa.

Published: August 2019

Objetivo: Através de uma Revisão da Literatura, o trabalho busca consolidar informações sobre o desenvolvimento do sistema estomatognático, durante a vida intrauterina. Foram realizadas pesquisas sobre o tema abordado, nas seguintes bases de dados: Scielo, Medline; Bireme; Google Acadêmico e o PubMed, no intervalo de tempo de agosto de 2006 a junho de 2017. Livros publicados no mesmo período também foram consultados. Foram selecionados os artigos em português ou inglês, que contemplaram assuntos inerentes ao estudo. O desenvolvimento do sistema estomatognático acontece a partir do primeiro mês gestacional. A exposição materna a fatores de risco como infecções, traumatismos, desnutrição e consumo de drogas, pode deixar sequelas no feto, comprometendo estruturas e funções buco-dentais.
