In a contemporary society in which individuals declare themselves increasingly busy, it appears that the prominent modality of relaxation and sometimes getting informed is the Internet. The modern age is defined by consumerism, advanced technology, globalization and explosive development of Mass Media. Adolescents and young adults have various information alternatives at their disposal, but also a high level of expectations from their social and professional environment. Therefore, feelings of doubt, anxiety and uncertainty may emerge, and different inferiority complexes can develop, making one reach an impossibility of developing one's identity, in a form of compensatory mechanisms that appear at the attitudinal and behavioral level. The present article aims to present the results of studies performed by our team on different groups of subjects aged from 15 to 24 years, as a starting point for informing the population about the medical risks they are exposed to, to prevent the effects of these behaviours that affect the overall functioning of the individual.

In the practice of organizations, we notice the existence of a problem which influences negatively the operating parameters of a product and it has to be very accurately identified and proposals have to be drawn-up in order to remove it. This paper presents a method for assessing the quality of welding by applying one of the classic instruments of quality management. The clauses that generate welding defects are identified and classified. The causes are also grouped in two large categories: positive causes and negative causes depending on the effect they have on the studied problem. An Ishikawa diagram with a new formula 4M+4RM was proposed, to separate the positive causes from the negative ones. The importance of this method is also mentioned in the analysis of quality products.

The paper presents the results of a study concerning the use of the Ishikawa diagram in analyzing the causes that determine a non-quality problem in the operation of a automotive. The studied problem was “the pressure loss on the high pressure branch in the diesel supply system of the COMMON RAIL motor”. All the possible, main and secondary causes that could generate the studied problem were identified. We determined many possible causes and potential sub-causes and we grouped them into three main causes of the defect: a) causes determined by errors of fabrication/ manufacturing of system components; b) causes determined by faulty exploitation of the automotive; c) causes determined by inappropriate service. We regrouped all the secondary causes in categories of M type and there resulted: 5 categories of secondary causes of repairs in Service which included the use of spare parts with manufacturing errors, conventionally noted MS (Man-service, Methods-service, Materials-service, Machines-service, Environment-service);2 categories of secondary causes due to the operating mode of the motor car, conventionally noted ME (Materials-exploitation, Man-exploitation). All causes and secondary causes described a new Ishikawa diagram, model named in the paper 5MS + 2ME. This diagram performed in a detailed form is presented in the paper.

In this paper we present a study that was conducted to determine the classification of causes that generate defects in products obtained by injection of plastic material. A classification of the causes of defects is made by applying a quality management tool - the Ishikawa diagram. The causes are grouped into M categories, for defects generated by the design process and for defects generated by the injection process. A new model of the diagram is created by composing two fish skeletons (model 4M + 5M). At the end of the paper, the importance of the Ishikawa diagram is shown.
