    The study is a novelty because was elaborated on a group of students in the academic environment in France. Following the documented steps, I have noticed that several questionnaires have been used in order to identify stress levels in the academic environment. The case study presented in this article consists in a questionnaire meant to identify stress factors. There are several factors that are likely to cause stress: changes to routine, time pressure, difficult tasks, too much homework’s, financial state, sleep schedule and physical work conditions. I believe that stress management results could be visible if we can motivate people to adjust their behavior and life styl

    Contribution to the measurement of stress level post stress management training

    The case study presented in this article consists in a questionnaire meant to detect stress in employees after a stress management training session. The study is a novelty because was elaborated on a group of employees after they learn one months about occupational stress management. Over the time, many of the studies conducted in the field of stress focus on a combination of the factors like this: reducting stress exposure and developing programes for physical exercises - relaxation and meditation. It is very important to have information about stress because it can change the perspective of life and the way in which we can see that a situasion can be negative or positive one

    Integral curses of the disc drama model with fundamental dynamic characteristics tt-ds

    The paper deals with the dynamic response of mechanisms with standardized inertial and mechanical characteristics. Moment or inertial mass is periodically variable with displacement, and torque or mechanical force are periodically variable with displacement and represented by linear, square or cubic functions in relation to speed. In this paper both the inertial moment and the torque variation were used for the T-shift. For the variations of torque torque versus speed, the straight-inclined DS was used. Comparable results charts are based on computer programs

    Impact on quality of production using 5S method

    Get PDF
    Efficient and quality work requires a clean environment, security and rigor. The principle of 5S, namely Seiri, Seiton, Seiso, Seiketsu, Shitsuke, allows the construction of a functional working environment, driven by simple, precise and efficient rules. The 5S is the foundation on which progress is being made, the deployment of Lean-manufacturing means and methods, being a lever of change management. At the same time, the 5S can be considered as the basic rules of order, discipline, unmistakable preliminaries for a whole improvement project

    Unique method for structural synthesis of the machines planed with bars and dogs

    The planar mechanisms with articulated bars and gears (which we will simply note MeBaRd) are part of the general planar mechanics category. Although structural structural studies have been carried out [7], the structural synthesis of bars and wheels can be approached as a distinct problem. Some papers refer directly to a certain class of mechanisms, such as planetary mechanisms [1], [2], others stop on subsystems with zero mobility, called structural groups with toothed elements [6], [8]. In this paper, developing some ideas presented in [3], [5], a general algorithm for unitary structural synthesis of MeBaRd was developed and developed, having the input parameters: M - the degree of mobility and N - the number of contours

    Efficiency of a production line by application of the Kanban method

    Get PDF
    This paper aims to present the study on the implementation of the Kanban system for the "bicycle wheel" benchmark in demand-side conditions. Due to variations in customer orders, production on the "Wheels" line is inconsistent, with work volume being also variable. In this way, dead times appear, production stagnating at some times, and in others being overstretched. There is a problem of finding a method of leveling the production, which also leads to a better performance of the Logistics department within the "Expedition" service. The work was carried out following a study with data provided by SC MECHROM INDUSTRY SRL, a member of the CAMPAGNOLO group, a bicycle manufacturing company, exclusively for performance sport

    The role of endothelium in covid-19

    The 2019 novel coronavirus, known as severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19), is causing a global pandemic. The virus primarily affects the upper and lower respiratory tracts and raises the risk of a variety of non-pulmonary consequences, the most severe and possibly fatal of which are cardiovascular problems. Data show that almost one-third of the patients with a moderate or severe form of COVID-19 had preexisting cardiovascular comorbidities such as diabetes mellitus, obesity, hypertension, heart failure, or coronary artery disease. SARS-CoV2 causes hyper inflammation, hypoxia, apoptosis, and a renin–angiotensin system imbalance in a variety of cell types, primarily endothelial cells. Profound endothelial dysfunction associated with COVID-19 can be the cause of impaired organ perfusion that may generate acute myocardial injury, renal failure, and a procoagulant state resulting in thromboembolic events. We discuss the most recent results on the involvement of endothelial dysfunction in the pathogenesis of COVID-19 in patients with cardiometabolic diseases in this review. We also provide insights on treatments that may reduce the severity of this viral infection
