Predicting Factors of the Intention to Leave in Public Service: The Case of the National Cancer Institute - Inca - Rio de Janeiro - Brazil
Flavia Freguglia de Lima and Marcia Cristina Rodrigues Cova
The difficulty of retaining its servers has been one of the challenges faced by Brazilian public organizations. Although many professionals are attracted to the public service due to greater security in labor relations, stability and attractive remuneration, factors related to job dissatisfaction and lack of organizational commitment make many employees decide to leave the organization they are part of and seek other institutions to work. This article seeks to understand how the phenomenon of intention to leave has been occurring at the National Cancer Institute, identifying the profile of the employees who wish to leave the organization, as well as the possible predictive factors of the intention to leave. To this end, a qualitative methodology is used, with a case study. Data collection was obtained through documentary research. Data analysis was conducted based on the content analysis technique. 186 processes of movement and shutdown opened at the agency between May 2017 and February 2020 were analyzed. The results show that turnover is not restricted to a sector or unit and also that the reduction in the intention to leave demands strategies to maintain employee satisfaction; increased affective organizational commitment; and improvement in the level of perception of organizational support.

Modeling the Impact of Total Quality Management on Costs and Customer Satisfactions of Kuwaiti Courier Service Companies Using Information Index
Raed A. Al-Husain and Basel M. Al-Eideh
The main objective of this paper is to study the impact of total quality management (TQM) on the cost and customer satisfaction of Kuwaiti courier service companies. An information index (II) and autoregressive integrated moving averages (ARIMA) models have been developed to estimate the future propensity and measure the impact of applying TQM on the cost and customer satisfaction of Kuwaiti courier service companies. Data from 23 courier service companies in Kuwait were used to estimate the models. The proposed models of the TQM factors information index shows that ARIMA (2,0,1) is found to be an appropriate model to fit CTQMII for the costs group, whereas the ARIMA (1,1,1) model is found to be an appropriate model to fit STQMII for the customer satisfaction group. Also, the ARIMA (0,1,0) model is found to be an appropriate model to fit TQMII for both groups. This study is motivated predominately by the growing attention of the worldwide public to various factors affecting the TQM.
Keywords: Statistical analysis, information index, total quality management, ARIMA models.

Objective: This was a cross-sectional study performed at Laquintinie Hospital and General Hospital in Douala-Cameroon from 2014 to 2016. The study enrolled 842 dyspeptic patients (370 males and 472 females; mean age, 41 ± 17 years). Each subject gave a written consent. The Cameroon National Ethical Committee approved the study. Socio-demographic data and risk factors exposure were obtained from participant using a structural questionnaire. Direct inquiry about relevant gastro-duodenal clinical signs and indications of gastroscopy were recorded for all participants. From each patients, biopsy samples were collected for H. pylori detection using histologic examination and urease test.
Results: The overall prevalence of H. pylori infection was 73.2%. Subjects from 31 to 40 years old were significantly more infected (p = 0.006) than others. History of gastric cancer (p = 0.008), socioeconomic status (p = 0.027), alcohol (p = 0.012) and NSAIDs (p = 0.0001) consumption were significantly linked to infection. Anemia and vomiting were the most frequent clinical signs among infected patients. Infected patients were significantly prone to develop duodenal ulcer (P < 0.0001), chronic gastritis (P=0.0409), and erosive gastritis (P=0.005) than uninfected ones. Thus these gastric mucosa features are highly suggestive of H. pylori infection in our milieu.

Khaled Abuktaish and Shaker Jaralla Alkshali
The study aimed to verify the effect of strategic intelligence on the competitive advantage in Jordanian Extractive and Mining Companies. To achieve the aims of the study, a descriptive analytical method was used. The study was conducted on a sample consisting of (231) managers in these companies. To measure strategic intelligence, a scale of five dimensions was used: foresight, system thinking, vision, motivation and partnership. To measure the competitive advantage, use a four-dimensional scale: quality, cost, flexibility and delivery. The study found that there were medium levels for all dimensions of strategic intelligence, while the levels of dimensions of competitive advantage were all high. It was also found that there was a significant effect of all dimensions of strategic intelligence except for system thinking, and that there was a significant effect of strategic intelligence on all dimensions of competitive advantage.
Keywords: Strategic Intelligance, Competitive Advantage, Extractive and Mining Companies, Jordan.

Modélisation De La Dégradation Environnementale Du Paysage Du Bassin Aurifère De La Riviere Perma (Commune De Natitingou, Benin)
Seko Ossinra M. Alphonse, Tchibozo Eric A.M., Kaki Christophe and Clédjo Placide F.G.A
Dans le bassin aurifère de la Perma, la dynamique de l’occupation du sol se réfère non seulement aux activités agricoles, mais aussi à celles de l’exploitation artisanale de l’or. L’objectif de la présente étude est d’étudier la dégradation environnementale du périmètre d’exploitation de l’or à Perma. La méthodologie utilisée est constituée d’une approche de cartographie diachronique et prédictive par télédétection et SIG de la dynamique de l’occupation du sol. Les périodes retenues sont celle de 2014 à 2019 correspondantes à une activité intense d’orpaillage et celle de 2019 à 2025 pour des perspectives à l’horizon 2025.
Les résultats obtenus montrent une régression des écosystèmes forestiers et savanicoles qui s’accentue avec l’augmentation de l’aire totale des sites d’exploitation de l’or, conséquence d’une dégradation des terres par anthropisation. Dans la zone d’étude, la forêt-galerie au Nord-Ouest autour de la rivière Kouminsiyarikou, la forêt claire au Nord-Est du long de la rivière Perma et la savane boisée et saxicole au Sud-Est sur les structures plissées, sont particulièrement affectées avec d’importantes régressions avoisinant respectivement - 24,13 %, - 27,59 % et -15,18% de terres dégradées pendant la période d’étude indiquée (2014-2019) puis de faibles régressions de - 4,44%, - 1,01% et - 5,72 % durant la période d’étude projetée. La superficie rocheuse a ainsi augmenté de +50,21% au cours de la première période et projetée de 24,18% sur la deuxième avec un endurcissement observé sur les sols exposés des sites abandonnés par l’exploitation de l’or et la dégradation du couvert végétal. Au Centre et au Sud du secteur d’étude autour de la rivière Perma, des installations humaines et l’exploitation de l’or pendant la période 2019-2025, dégraderont le paysage et engendreront l’ensablement de la rivière Perma et de ses affluents. Le secteur est caractérisé par une augmentation continue des superficies d’anciens sites d’exploitation d’or abandonnés couverts de sol remanié qui participe à la dégradation totale de l’environnement.

Influence of Conduit Properties on Magma Ascent
Francoise Martine Enyegue A Nyam, Igor Collins Djouda Paguem, Fosso kegne S., Kemgang Ghomsi Franck Eitel, Parfait Clement Bounoung and Marcellin Bikoro Bi-Alou
In this paper, we studied the upward migration of magma to the Earth's surface using Jeffrey's fluid model. The question is formulated using discontinuities in the subsurface layers, the variation in pressure of the magma during its ascent to describe the trajectory. We consider that the walls that define the channel shrink or increase in diameter as a function of the decrease or increase in eruption during magma ascent. This variation leads to a turbulent flow regime. To build our model we considered that the magma in these irregular conduits oscillates at velocity c and wavelength λ. The nonlinear equations governing the problem studied are simplified by approximating the long-wavelength hypothesis, the low Reynolds and Grashoff numbers. Using the perturbation approach, the exact solutions for temperature, velocity, and pressure are obtained. The influence of the physical properties of the pipe, the magnetic field (M), the permeability (σ), the perturbation (N), and the dimensional numbers are presented graphically. It is shown that the flow dynamics are strongly controlled by the permeability of the pipe, the Grashof number, and the perturbation. This could explain the potential mechanism of a volcanic eruption.
Keywords: Magma ascent, pipe properties, disturbance (perturbation).

Contribution to the Elimination of Pollution from Industrial Wastewater by Lime and the Polalumine
Iman Chaouki, Latifa Mouhir, Mohamed Fekhaoui and Salah Souabi
The objective of this work is to optimize the coagulation-flocculation step of the WWTP of the SALAM GAZ SKHIRATE filling center and study the combination of coagulant used with lime.
The tests of coagulation were performed using a jar- test bench, consisting of a series of six beakers. The series includes a control suspension without addition of coagulant and the same suspension subjected to increasing doses of coagulant (Polalumine only, lime only and combination of Polalumine and lime).
The coagulation- flocculation tests have shown that the application of Polalumine at a dose of 4 ml/l removes 62% of the turbidity and 67% of COD, while the application of the lime at a dose of 500 mg/l allows eliminating 52% of the turbidity and 65% of the COD. The combination of a dose of 4 ml/l of Polalumine and 500 mg/l of lime reduces turbidity of 71% and 77% of the COD.
It appears from the overall results that the best treatment by coagulation-flocculation is obtained by the application of a single dose Polalumine 4 ml/l and the combination of 4 ml/l of Polalumine and 500 mg/l of the lime.
Keywords: Industrial wastewater, Polalumine, lime, turbidity, COD.

The Origin Theory and Epidemic Distribution Characteristics of the Novel Coronavirus 2019-nCoV
Wu Jiang
Listed examples of virus transmission epidemics caused by sunspot cycle changes that can be strongly transmitted through the air, and analyzed the mechanism that promotes the generation of new viruses. Innovation from the schematic diagram of the changes in the combined force of the hydrodynamic effect of the sun sweeping the earth and the sweeping force, obtain the places that are prone to vortices are 30 degrees north latitude and 30 degrees south latitude on the east coast of the mainland. And the curved continental lines are perfect, the range of the light vortex generated is more obviously, and the effect is stronger. It is inferred that the light vortex produces the special amplified energy so make the virus mutate to produce a new highly infectious novel coronavirus. The earliest known place and time of the novel coronavirus origin are consistent with the reasoning of the new theory. Because the radius and frequency of the light vortex are different, the resulting virus strains are also different. Moreover, the fatality rate in the light vortex area is much higher than that in the non-light vortex area, indicating that the virus's toxicity and lethality are higher in the light vortex area, so it can explain why Russia, India, and countries in the African equatorial region mortality are much lower than the United States, Italy, Spain and Brazil. Finally, preventive and recommended measures are proposed.
