Objective:to study melatonin metabolism and hormonal status of pregnant women in different seasons of the year, depending on the sex of the fetus. Materials and methods:538 women were examined at the time of physiological gestation of 37-40 weeks. The first group — 286 pregnant women with female fetuses and the second group — 254 pregnant with male fetuses. Estimation of the hormonal status included the determination of the level of cortisol, estradiol, adrenocorticotropic hormone, progesterone, testosterone in the blood and melatonin in the urine of pregnant women.Results:the level of 6-sulphatoxymelatonin in the morning urine, regardless of the sex of the fetus, was higher in the seasons of the year with the predominance of the dark time of the day. Absolute levels of 6-sulphatoxymelatonin in urine in all women in 37-40 weeks of gestation were the lowest in the light-saturated summer and spring months of the year, while in the winter period its parameters were maximal. Melatonin production was statistically significantly higher in pregnant women with female fetuses during the fall and winter periods of the year. Regardless of the time of the year, in pregnant women with female fetuses, the absolute levels of estradiol and progesterone were higher than in the case of the male fetus. The highest values in the case of the female fetus were noted in the spring. Testosterone production was significantly higher in pregnant women with male fetuses mainly in the spring season. Stress resistance of pregnant women was higher in the summer months. Depending on the “sex of the fetus” factor, stress hormones in the summer had the highest values in pregnant women with male fetuses.Conclusions:the sex of the fetus is a significant factor affecting the seasonal variability of melatonin production, sexual and stress hormones in pregnant women due to the formation of the specificity of the systemic signaling between the maternal and the fetal organism in the dynamics of pregnancy.
Cultural Impact of Scholars in the Andalusian Emirate (138-442 AH / 756-1031 AD)
Authors: Shuja Alotaibi Hussah Hindi
Published: October 2018

Scholars during the Islamic ages played a significant role in the development of society, culture, and various other fields including economy, science, literature and arts etc. With the fragmentation of Abbasid caliphate, various rulers became independent and formed parallel caliphates, and adopted their own approaches towards development. Andalusian emirate is one such independent kingdom in southern Spain, which disowned its diligence to the Islamic caliphate, and adopted its own approaches to the development of the region. Scholars during this period played a significant role in transfer of technology from foreign regions, leading innovation in various sciences such as agronomy, astrology, astronomy, mathematics, arts, philosophy etc. All these events led to a significant impact on the culture and society, which are discussed and presented in this paper.
Three Early Islamic Stelae Found in the Malay Archipelago and Its Artistic Relation with the Eastern Islamic World

Published: October 2018

This study examined the decorative elements present on three early Islamic stelae – the Champa Pillar (1035CE), Putri Makhdarah’s tombstone (1048CE) and Fatimah’s tombstone (1082CE) – which were found in the Malay Archipelago and dated to the eleventh century CE. These objects are of tremendous significance as they are the earliest Islamic evidence in Southeast Asia that indicates Muslim presence in the region. Regrettably, although is it acknowledged that one of the earliest cultural influences that spread towards the Malay Archipelago is Persian, the artistic dimensions of the stelae are rarely discussed in terms of its influence and connection with the eastern Islamic lands after the Muslim conquest in the seventh century CE. This is because previous studies are more concerned with the inscription and material from the archaeological, historical and palaeographic approach rather than art history. Therefore, this study adopted the art historical method where the analysis concerned the development and influence of the Islamic art in the region. Based on the analysis, it was discovered that these stelae have connections in terms of their artistic repertoire, format, type and context of certain motifs used with the ones found in the eastern Islamic lands, namely Iran and Transoxiana. This connection is particularly evident in the type of calligraphy used, involving round script and foliated Kufic, as well as the use of lamp motif (misbah) in mihrab images. Both have been found to be extensively used in Iran and Transoxiana for tombstones, gravestones, mausoleums, commemorative texts and Quranic manuscripts, contemporary with the development of Islamic art in the region. Hence, the findings from this analysis indicate that the source of Islamic decorative elements used by the Malays in their Islamic art stemmed from Iran and Transoxiana and was heavily rooted in the Turco-Persian influence since the coming of Islam to Southeast Asia.
Sejarah Persempadanan Kelantan-Patani: Kesannya kepada Evolusi Ketamadunan Islam dan Politi Melayu Semenanjung The History of Kelantan-Patani Border Delineation: Its Effects to the Islamic Civilisational Evolution of Malay Peninsula Polities
Authors: Alias Nizamuddin , Ahamat Haniff
Published: October 2018

The Kelantan-Patani border was determined through the Anglo-Siamese Treaty 1909. The treaty changed the previous border of the two states by giving the west bank of Golok River to Thailand (Patani), while giving the district of Jeli to Malaysia (Kelantan). This article intends to study a few objectives. They are inter alia, firstly to study the importance of rivers to Malay polities in general and to see its relations to Golok River. Secondly, this article studies the western part of Kelantan border before the 1909 treaty. Thirdly, this article also explains the border delineation process which was determined by the Anglo-Siamese 1909 Treaty. Fourthly, the article analyses the effects of Kelantan-Patani border delineation to the evolution of Malay Peninsula polities. The method of the research involves black letter law method and legal history method. Documents analysed include the Anglo-Siamese Treaty 1909, books, historical documents related to the negotiations in Kelantan-Patani border delineation process, as well as diplomatic correspondence between the British and Siamese officials. The study finds that the reorganisation process done by Britain and Siam did not only comprise the determination, acquisition and territorial losses by both powers, but also isolated Patani from other Malay Peninsula polities. Moreover, it brought unintended consequences due to the British failure in considering Malay civilisation and cultural factors in the process of determining the border delineation.

OBJECTIVE

The goal of this study was to describe the development and validation of an artificial intelligence–based, deep learning algorithm (DLA) for the detection of referable diabetic retinopathy (DR).

RESEARCH DESIGN AND METHODS

A DLA using a convolutional neural network was developed for automated detection of vision-threatening referable DR (preproliferative DR or worse, diabetic macular edema, or both). The DLA was tested by using a set of 106,244 nonstereoscopic retinal images. A panel of ophthalmologists graded DR severity in retinal photographs included in the development and internal validation data sets (n = 71,043); a reference standard grading was assigned once three graders achieved consistent grading outcomes. For external validation, we tested our DLA using 35,201 images of 14,520 eyes (904 eyes with any DR; 401 eyes with vision-threatening referable DR) from population-based cohorts of Malays, Caucasian Australians, and Indigenous Australians.

RESULTS

Among the 71,043 retinal images in the training and validation data sets, 12,329 showed vision-threatening referable DR. In the internal validation data set, the area under the curve (AUC), sensitivity, and specificity of the DLA for vision-threatening referable DR were 0.989, 97.0%, and 91.4%, respectively. Testing against the independent, multiethnic data set achieved an AUC, sensitivity, and specificity of 0.955, 92.5%, and 98.5%, respectively. Among false-positive cases, 85.6% were due to a misclassification of mild or moderate DR. Undetected intraretinal microvascular abnormalities accounted for 77.3% of all false-negative cases.

CONCLUSIONS

This artificial intelligence–based DLA can be used with high accuracy in the detection of vision-threatening referable DR in retinal images. This technology offers potential to increase the efficiency and accessibility of DR screening programs.

MECHANICAL PROPERTIES OF SERVOVITE FILMS FORMED IN DURING FRICTION AQUEOUS SOLUTIONS OF CARBOXYLIC ACIDS
Authors: Burlakova V. E. , Drogan E. G. , Tyurin A. I. , Pirozhkova T. S.
Published: October 2018

Introduction. The effect of the organic component nature in the systematic series of monocarboxylic acids on the tribological characteristics of the brass-steel friction pair in aqueous solutions is described. Dependence of the mechanical-and-physical properties of the antifriction films formed during friction on the nature of the lubricating composition is investigated. The work objectives are to study the applicability of carboxylic acids as an antifriction lubricant component; to assess their effect on the mechanical properties of the servovite film formed under the brass – steel friction.

Materials and Methods. Tribological studies of the brass-steel friction pair on the AE-5 end-type friction machine are carried out. Roughness parameters of the servovite  film were determined through the optical profilometry. The microgeometry and the object structure at the nanoscale were considered using atomic force microscopy. The mechanical characteristics of the antifriction film were investigated using the instrument nanoindentation.

Research Results. Tribological characteristics of the brass-steel tribocoupling and mechanical-and-physical properties of the servovite film formed during friction in the “brass – aqueous solution of carboxylic acid – steel” system were studied. It is established that the friction factor reduces when increasing the hydrocarbon radical length. The dimensional effects are found in the mechanical and tribological properties of the servovite film formed on the surface of the friction interaction in the carboxylic acids.

Discussion and Conclusions. The study results show that the friction interaction on the wearing surface in the aqueous solutions of carboxylic acids forms a nanostructured servovite film which drops the friction factor. Its mechanical, physical and tribological parameters depend on the composition of the model lubricating medium. It is determined that the local mechanical-and-physical properties depend on the method of producing the servovite layer, the load and the size of the deformation zone. The results obtained can be used in the development of lubricants.
REPAIRING THE MAIN SHAFT OF DRYER TOASTER
Authors: Lyudmirsky Y. G. , Assaulenko S. S.
Published: October 2018

Introduction. The sources of damage and wear of the main shaft of the  drier  toaster  are  analyzed.  The  repair  know-how  and welding operations execution limitations which must be considered when developing the technique providing the restoration of the structure performance  features are studied. The work objective is to develop a technique of repair without dismantling  for  the  main  toaster  shaft.  To  solve  the  task,  a design   repair   structure   was   installed,   and   postwelding operations  that  meet  the  engineering  and  regulatory requirements for this structure were performed.

Materials   and   Methods.   In   “Kompas   3D”   software,   the following models were developed: integral shaft (project shaft design); damaged shaft as a result of long-term operation (more than  15  years);  and  damaged  shaft  with  a  welded  repair structure. Numerical simulation of the stress-strain state (SSS) was carried out.

Research Results. Software for the computational modeling of the repair structure SSS is developed. The repair shaft structure in which the maximum stresses do not exceed the shaft stresses in the project design is obtained using the model. To eliminate the aggressive medium effect on the corrosion fatigue strength of the shaft, an insulating method is used. A technique for mounting  the  repair  structure  to  the  shaft  allowing  for  the outrun limitation 0.12 mm is developed.

Discussion and Conclusions. Torsion shafts damaged deeply by wear and corrosion are considered. To restore their structural integrity, it is worthwhile using the following complex of techniques:

— constructive (consists in the installation of optional parts that compensate for insufficient strength, and provides a reduction in stress concentration in the most loaded zones);

— processing (reduces residual welding stresses due to the reasonable sequence of deformation that contributes to generating favorable residual compressive stresses);

—  isolation  (is  based  on  the  application  of  anticorrosion coatings).

The economic expediency of the developed repair technique is obvious. The repairing of the shaft without dismantling costs 180,000 rubles, while a new shaft costs 3.8 million rubles.
FORECASTING THE GROUNDWATER LEVEL OF CEMENT RAW MATERIALS DEPOSIT BASED ON DYNAMIC NEIGHBORHOOD MODELS
Authors: Sedykh I. A.
Published: October 2018

Introduction. The development of a mathematical model for the groundwater level of a deposit of cement raw materials located in the Zadonian-Yelets aquifer, which is the principal domestic water supply source for the city of Lipetsk, is considered. Therefore, it is necessary to provide ongoing monitoring and to have the possibility to  predict the water level under the field development. The work objectives are the identification  and  study of a  dynamic  neighborhood  model with variable hierarchical neighborhoods of the groundwater level that enables to adequately predict value of the water level in the examined wells.

Materials and Methods. The definition of a dynamic neighborhood model with variable hierarchical neighborhoods is given, differing by time-varying double-level neighborhood communications between the first- and second-level nodes. At each next discrete instant of time, the neighborhood model nodes change their state under the influence of the online parameters and node states included in their neighborhood. As a subcase, we consider a model with line state recalculation functions. Parametric identification of the dynamic neighborhood model consists in finding the system parameters for each second-level node, and is based on the ordinary least squares.

Research Results. A linear dynamic neighborhood model with variable hierarchical neighborhoods for predicting the groundwater level in a cement raw material deposit located in the Zadonian-Yelets aquifer is developed. The software using C++ is developed for the parametric identification and simulation of the functioning of the dynamic neighborhood model under consideration. It enables to determine parameters of the node state recalculation functions for a given structure, and  also  to  predict  the  model  behavior  in  the  operation process. A hierarchical structure is given, and a parametric identification of the linear dynamic neighborhood model of the groundwater level is carried out. After the parametric identification on the teaching data selection, the mathematical model is checked on the test sample.

Discussion and Conclusions. The obtained average ratio errors of the identification and forecast suggest the developed model validity  and  enable  to  recommend  it  for  predicting  the underground water level of a cement raw materials deposit.
The concepts of universe, cosmos and microcosm in the cosmological philosophy of Heraclitus of Ephesus
Authors:   Lomonosov Moscow State University, Bakina Valentina Ivanovna
Published: October 2018

The study gives different interpretations of the concept of cosmos by Heraclitus of Ephesus in both ancient and modern philosophy, including the Russian one. A new scientific and philosophical justification of the interpretation of the most important cosmological terms by Heraclitus and his construction of the universe are presented on the basis of works of Ancient Greek philosophers which have no clear statement of Ephesian thinker’s views on the structure of the universe. By a case study of the Work of Heraclitus of Ephesus on Nature, the author illustrates the consistent concept of the universe structure by Heraclitus which has always been considered “dark” and incomprehensible. The research concludes that in order to avoid contradictions in cosmological studies, philosophers should clearly define the meaning of the pivotal cosmological concepts such as universe, cosmos, microcosm.

Published: October 2018

The study analyzes the main changes in the reforms of a control system of physical education and sports in Kemerovo region in 1985–1991. The author proved that there were the state and amateur forms of management and arrangement of physical education and sports in Soviet Russia. They were significantly changed due to fostering the social and economic development of the country and restructuring. The same processes took place in regions. In 1985–1991, the management structure of physical education and sports in Kemerovo region was rearranged. In this period, the party and Komsomol organizations started to lose their leading role in sports management. In 1991, they were eliminated. Besides, voluntary sports societies of trade unions and physical education and sports committees were restructured. The author identified that reforms in the field under review were implemented in terms of increased crises in the society that had a negative impact on the physical education and sports development in Kemerovo region.

Published: October 2018

The paper revealed the attitude of Russian teachers, educators worked at reformatories and legal experts to smoking as a social problem. The lack of historical studies on this issue and the social disease surge explained the relevance of the research. The author considered the social scientific approaches of Russian teachers and lawyers to devising a set of anti-smoking measures by identifying the causes of the mass prevalence of tobacco consumption, developing and implementing public initiatives against it in practice. Control of smoking and problems in this regard were reviewed in the context of the social and economic development of the society. The research was based on the proceedings of teaching congresses in the late 19th – early 20th centuries. The author identified why smoking was so popular among young people and presented methods for reducing it. The paper demonstrated the views of most active teachers and lawyers who took part in the above-mentioned congresses.
The legal significance of the state environmental review when solving urban environmental problems
Authors:   Director General,  Legal Solutions Center Legalight LLC, Kovalenko Yulia Nikolaevna
Published: October 2018

The research analyzes the legal nature of an agree-ment between persons involved in common owner-ship. The author proves that in theoretical and prac-tical terms the most proper legal qualification of agreements between co-owners should be based on the corporate rather than the real concept of percep-tion of co-ownership relations, therefore, the above-mentioned instruments are regarded as resolutions of meetings. The author makes this conclusion bas-ing upon the literal interpretation of legislation, the analysis of the jurisprudence and practices of for-eign countries. An advantage of the legal qualifica-tion of agreements between co-owners as resolu-tions of meetings is the possibility to unify the in-terpretation of the legal nature of common owner-ship relations and eliminate the gap in the law. Such an approach allows co-owners to be guided by the provisions of Chapter 9.1 of the Civil Code of the Russian Federation when making decisions as well as to invoke these provisions when challenging the decisions.

Authors:   Russian State University of Justice, Shakk Serin Nizarovna
Published: October 2018

The research considers the theoretical and proce-dural ideas about sworn attorneys as advocates. The study examines two forms of procedural protection: legal representation and advocacy. The paper at-tempts to analyze their fundamental differences in both the legal nature and the procedural aspect of the participation of a legal representative in civil proceedings. Based on the research findings, the author reveals that sworn attorneys possess the characteristics of advocates. The study analyzes the Court Charters of 1864 that have introduced the in-stitution of sworn attorneys and determined the conditions for holding the post of sworn attorneys, their rights and duties. It is concluded that the in-volvement of a sworn attorney in the proceedings makes them competitive. Besides, the advocate pro-cedural activity of the legal representatives can be applied in modern civil proceedings for the most effective implementation of justice.

Prospects for Collective Security Cooperation in the Gulf
Authors: Albasoos Hani
Published: October 2018

The process of establishing a new security structure in the Gulf should take into consideration the failures of the past and the political differences among GCC countries which have been impeding collective security in the Gulf. Collective security arrangements should consider the strategic circumstances that currently exist and the numerous security problems which have implications for security beyond the region itself. These include the Iraqi security situation, Iranian foreign policy and its nuclear and missile programmes, the stability of Yemen, borders disputes, and the deepening Sunni-Shia divide with its destabilising political and social effects on the region. Cooperation in the Gulf should not be limited to military aspects, but must also include economic development, counterterrorism, disaster response, environmental, social and cultural issues. Gulf States should institutionalise their security structures which is important for the establishment of a strong joint command needed to achieve collective security and prosperity and effectively leading to development and stability in the region.
The Arabic Social researches centers: Contributions and Challenges
Authors: Al-Maizar Hind
Published: October 2018

Developed societies are interested in creating research centers to make future decisions. Therefore, society’s various institutions and sectors became more dependent on these centers because they are one of the pillars of development in different fields for its functions and roles that contribute to design social policy. Recently, these centers which are concerned with social affairs in the Arab countries have spread, which raises the question: What are their contributions? What are the challenges they face? This study employed clerical research and comprehensive survey of the publications of these centers, both in print and electronically. Results showed that there are variations in the affiliation of research centers in each country, where most of them are governmental and belong to universities, especially in the Gulf countries. They also vary in the date of establishment which are more than sixty years in Egypt, and more than thirty years in Jordan, and a relatively modern establishment in the Gulf States. The relatively new growing up in the Gulf States. The researcher reviewed two models of Arab research centers as they are representing the centers that most contributed to the field of the Arab Social. Thought, namely: National Center for Social and Criminological Research in Egypt, 1955, which is a governmental center and Center for Arab Unity Studies in Beirut, 1975, which is a non-governmental center. The researcher presents a set of challenges that may face these centers to explore Arab future on a social level.
Rock Inscription from the Area of Ja’alanbani Bu Hasan, Sultanate of Oman
Authors: Al-Jahwari Nasser Said
Published: October 2018

This paper discusses a unique rock inscription found during the 2011 survey conducted by the author in the area of Ja’alan Bani Bu Hasan in the Southern Sharqiyah Province, Oman. This type of inscriptions is not recorded in the northern part of Oman, and is frequently found in the south. Since the beginning of the twentieth century, several amateurs and travelers have reported the discovery of many of these inscriptions in the Province of Dhofar. Several of these inscriptions have been found near tombs and triliths in Dhofar. This is also the case with the Ja’alan’s rock inscription which was found near one of the triliths recorded in the area of Saih al-Sa’ad. This type of inscription was not previously found by any traveler or researcher working in the northern and central parts of Oman. For example, in 1970s, the British expedition carried out an archaeological survey in the eastern region of Oman and documented a number of archaeological features, including a large number of prehistoric tombs and triliths, but did not find such an inscription. Hence, the discovery of Ja’alan rock inscription with its letters or symbols is the first of its kind in the eastern region of Oman. Although they have been frequently found, their symbols or characters have not yet been fully decoded. Therefore, the available information does not help understanding several related aspects including their content, meaning, purpose, as well as their dating, and who executed them; all of which remain unanswered. This paper attempts to present the Ja’alan inscription, and compare it with similar inscriptions from other areas, particularly Dhofar. This will be done in order to understand its content and dating, as well as the distribution of this type of inscriptions in Oman.
Evaluation of Climate Change Impacts on Cotton Yield using Cropsyst and Regression Models
Authors: Georgiou Pantazis , Koukouli Panagiota
Published: October 2018

The regional as well as the international crop production is expected to be influenced by climate change. This study describes an assessment of simulated potential cotton yield using CropSyst, a cropping systems simulation model, in Northern Greece. CropSyst was used under the General Circulation Model CGCM3.1/T63 of the climate change scenario SRES B1 for time periods of climate change 2020-2050 and 2070-2100 for two planting dates. Additionally, an appraisal of the relationship between climate variables, potential evapotranspiration and cotton yield was done based on regression models. Multiple linear regression models based on climate variables and potential evapotranspiration could be used as a simple tool for the prediction of crop yield changes in response to climate change in the future. The CropSyst simulation under SRES B1, resulted in an increase by 6% for the period 2020-2050 and a decrease by about 15% in cotton yield for 2070-2100. For the earlier planting date a higher increase and a slighter reduction was observed in cotton yield for 2020-2050 and 2070-2100, respectively. The results indicate that alteration of crop management practices, such as changing the planting date could be used as potential adaptation measures to address the impacts of climate change on cotton production.

Published: October 2018

In this article, a new technique is proposed to simulated two-dimensional Zakharov–Kuznetsov equation with the initial condition. The idea of this technique is based on Taylors' series in its derivation. Two test problems are presented to illustrate the performance of the new scheme. Analytical approximate solutions that we obtain are compared with variational iteration method (VIM) and homotopy analysis method (HAM). The results show that the new scheme is efficient and better than the other methods in accuracy and convergence.
The Constitution Of Special Relativity
Authors: Ghosh Tapan Kumar
Published: October 2018

Lorentz transformation relations of special relativity are generally derived for light like intervals in almost all texts. The procedure assumes invariance of spherical wave front equation in all inertial frames. This paper deals with the derivation of the transformation relations of event coordinates together with Doppler formula from a single treatment by constructing identical length and time standard under identical conditions in compared frames. To meet this end critical review of the postulates of Special Relativity in the perspective of equivalence of length, time and mass standard followed by the meaning of phase of clock in any inertial frame is presented. It has been shown that special relativity is in reality a supreme creation of human mind where identical length and time standards beingÂ  independent of the perspectiveÂ  are not naturally given but had been constructed under identical experimental condition in a scientific way so that observations from different frames can be compared using same system of units.

Water is the most important substance for life. Mineral waters are widely used as drinking water, and so that, it is important to determine the radon levels, and its risk in drinking water for public health and radiation protection. Radon concentration has been measured in the bottled natural mineral water samples commercially available in the Egyptian local market, using closed can technique. Radon concentration in water samples ranged from 0.93 - 6.89 Bql-1 and total annual effective dose ranged from 3.49 - 25.93 µSvy-1. The results indicate that radon concentrations in water samples lower than the recommended limit 11.1BqL-1 by EPA, and the annual effective dose of the samples are lower than the permissible international limit by EPA and WHO. The obtained results indicate that there is no significant public radiological risk related to radon ingested with drinking water in the present study.

Os estudos de adaptações de produtos voltados para pessoas com algum tipo de restrição física ou mobilidade reduzida vem aumentando gradativamente. Diante desse cenário, realizamos um panorama in loco para entender o ponto de vista do cadeirante como consumidor realizando compras e dos estabelecimentos em adquirir um produto adaptado aos cadeirantes, para então investigar a viabilidade de desenvolvimento de um produto adaptado. Foram desenvolvidos protocolos de análise dos cadeirantes e dos ambientes que proporcionasse maior abrangência de resultados possíveis em relação às principais dificuldades encontradas por pessoas com mobilidade reduzida, e também a visão dos supermercados sobre o tema abordado. Os resultados foram favoráveis para criação de um carrinho de supermercado adaptado a pessoas com restrição física, pois aumentaria a mobilidade e facilitaria o ato de realização de compras. Do ponto de vista dos responsáveis pelos estabelecimentos em relação a produtos e adaptações para cadeirante, estariam contribuindo para a inclusão social que é tão abordada na sociedade atual. Todavia, a modificação dos espaços físicos e o custo/benefício das alterações podem comprometer as condições de acessibilidade ao cadeirante nos estabelecimentos investigados.

analisar as habilidades gerenciais inerentes ao desempenho do trabalho gerencial do gestor da Universidade Federal do Pará – Campus Bragança/PA é o objetivo dessa pesquisa. Assim, a revisão teórica do trabalho baseou-se na literatura acerca da administração pública e a função gerencial na gestão pública. Em termos metodológicos, a abordagem utilizada nesta pesquisa foi do tipo qualitativa; quanto à técnica de coleta de dados, utilizou-se a entrevista estruturada, respondida pelo gestor da instituição. Para tanto, na fase de análise de dados, foram utilizadas as técnicas de análise de conteúdo. Portanto, ficou evidenciado, como resultado, que as habilidades gerenciais apresentadas na literatura são cruciais para o gestor público e que na administração pública o desafio de exercer a função de gestor torna-se muito maior por causa dos entraves da burocracia.

The health of Canadians depends on effective leadership among health care providers to facilitate the translation of new health discoveries into clinical practice. Clinician-scientists play an important role in bridging the gap between research and clinical practice, and require effective leadership skills to advance clinical practice successfully. To accelerate the leadership development in clinician scientist trainees, with the aim of developing strong leaders in administration and health advocacy, the Leaders in Medicine (LIM) training program at the University of Calgary created an Executive Leadership Coaching Program involving three phases: 1) an evidence-based evaluation tool, the Core Values IndexTM (CVI), that was used to identify the key drivers behind how individuals can be most effective in making their contribution; 2) small group workshops to debrief the results of the CVI assessment; and 3) one-on-one executive coaching sessions to facilitate the discovery, development and deployment of individual leadership capabilities. Coaching in leadership strategies enables clinician-scientist trainees to lead, influence, manage and deliver science-based improvements into the practice of medicine. We strongly recommend that other Canadian scientist-clinician training programs consider opportunities like the ones we offer to our LIM trainees. This training has important implications for the delivery of healthcare in Canada.

The sample is all of the millenial workforces in Belant Persada Ltd, which are58 employees. The data were collected through questionnaires and analyzed using Macro PROCESS by Hayes and Preacher through Statistical Package for the Social Sciences (SPSS). The results showed that work passion significantly affects work engagement and job satisfaction. While the work passion and work engagement are not direct and significant impact on the turnover intention. Furthermore, job satisfaction brings a significantly negative effect on turnover intention. This research failed to prove the existence of variable work engagement as a mediating variable. On the other hand, job satisfaction successfully serves as a mediating variable. It presents that work passion can determine turnover intention through increasing the job satisfaction.
