Le vieillissement est l’ensemble des processus physiologiques et psychologiques qui modifient la structure et les fonctions de l’organisme à partir de l’âge mûr. Il résulte des effets combinés de facteurs génétiques et environnementaux auxquels est soumis l’organisme tout au long de sa vie. Il s’agit d’un processus lent et progressif qui est la conséquence de l’action du temps sur les fonctions de l’organisme. La sénescence est le processus de vieillissement biologique, la suite des changements irréversibles dans un organisme qui conduisent à la mort. Ce processus physiologique débute après la phase de maturité et se traduit par la dégradation progressive et inéluctable des fonctions vitales : reproduction, motricité, système immunitaire, etc. La sénilité est la détérioration pathologique (liée à une maladie) des facultés physiques et mentales d’un individu âgé. Il existe trois modalités différentes de vieillissement : le vieillissement réussi, avec une absence ou une atteinte minime des fonctions physiologiques et une absence de pathologies ; le vieillissement habituel, avec des atteintes considérées comme physiologiques, liées à l’âge, de certaines fonctions, mais sans pathologies invalidantes ; le vieillissement pathologique lié à des maladies sévères évolutives ou compliquées et responsable le plus souvent d’une dépendance importante. À ces trois notions, il est important d’ajouter la notion de fragilité qui correspond à un état d’équilibre précaire avec l’impossibilité de répondre de façon adaptée à un stress qu’il soit médical, psychologique ou social. Après 65 ans, 10 à 20% des personnes peuvent être considérées comme fragiles et jusqu’à 50% après 85 ans. Il s’agit de personnes à haut risque d’hospitalisation, d’institutionnalisation et de décès. Les psychologues décrivent 5 grands types de personnalité liés au vieillissement, plus ou moins présents chez chacun : le mature est actif, tolérant et il s’adapte parfaitement à son évolution ; le pantouflard est passif, indulgent envers lui-même et il utilise son âge pour valoriser son inactivité ; le blindé est mentalement rigide, il a peur de la déchéance et s’enferme dans ses souvenirs de jeunesse ; le mécontent est amer, intolérant et pessimiste, anxieux face à la mort ; il en veut au monde entier de son état et de ses échecs ; le déprécié est dépressif, insatisfait de sa vie, sans estime de soi et envahi de regrets sur le passé ; il envisage la mort comme une délivrance ou une finalité. La solitude a un effet important sur la santé. Si nous comparons des personnes âgées qui conservent un vaste réseau de relations sociales à d’autres qui sont isolées, ces dernières auraient un risque supérieur de mort prématurée. Parler et échanger avec les autres est essentiel au bien-être. Stimuler la mémoire d’une personne âgée lui permettra de conserver son autonomie et de retarder la dépendance. Pour rester en forme, le cerveau doit travailler de manière complète. Plusieurs activités peuvent donc permettre à la personne dépendante de garder une bonne mémoire le plus longtemps possible : tenir un agenda, rédiger un journal, jouer à des jeux ou encore pratiquer des activités de création. Pour stimuler l’activité sociale d’une personne âgée, faire des rencontres est le meilleur moyen de rester en forme : rencontrer des personnes, poursuivre les activités qu’on aime, se servir du téléphone et même d’internet si possible. Il y a des personnes âgées qui ne parlent à personne pendant des semaines. Pour d’autres, le contact se limite aux relations avec les caissières des supermarchés. Avec l’âge, certains de nos aînés sont murés dans le silence. Pas par choix. Mais parce que les liens familiaux se sont distendus ou n’existent plus. Ils se retrouvent alors seuls, sans échange, sans partage et sans affection. Un des grands défis à relever pour l’avenir est la lutte contre la solitude des personnes âgées. Il faut savoir que la solitude est désormais considérée comme un facteur de risque de la maladie d’Alzheimer. Lutter contre la solitude, c’est prévenir l’exclusion, la pauvreté et la perte d’autonomie. Quel est le secret pour préserver son corps malgré les années ? Un peu d’activité physique et des repas équilibrés ! Pour lutter contre l’apparition des rides ou la chute des cheveux et conserver ses capacités physiques et cognitives, mieux vaut surveiller son assiette. Inutile d’aller chercher des produits miracles pour rester jeune : il faut commencer par manger mieux! Car en fonction des aliments qu’on choisit, on préserve son capital santé et on garde la forme durant de longues années. Les problèmes alimentaires spécifiques au vieillissement apparaissent à des âges variables et sont beaucoup plus marqués après 85 ans. Une bonne nutrition a un rôle de prévention de mieux en mieux connu sur les pathologies liées à l’âge. Un bon régime pour un senior comprend beaucoup de fruits et de légumes, du pain, du riz, des pâtes et des fibres. Il ne faut pas oublier le poisson, surtout le thon, le saumon et les sardines, et limiter les viandes rouges, en préférant le poulet, la dinde ou le lapin. Il faut aussi réduire le sel et le sucre, et tous les aliments riches en graisses comme les frites, les fritures ou les gâteaux. L’eau est très importante, mais on peut aussi boire du thé, des jus de fruits sans sucre ou du lait écrémé ou demi – écrémé. Il faut aussi de la vitamine D pour garder les os en bonne santé. On peut la trouver dans le poisson, la margarine et les céréales du petit déjeuner. Le corps produit tout seul la vitamine D quand il est exposé au soleil, il est donc conseillé de profiter du soleil de temps en temps avec de la protection pour aider le corps à produire cette vitamine. Étape naturelle de la vie d’une femme, la ménopause mérite quelques attentions sur le plan nutritionnel à cause de la modification du statut hormonal. Beaucoup de femmes prennent du poids à la cinquantaine. Souvent tout simplement parce que leur mode de vie change, avec moins de dépenses physiques et plus de temps pour apprécier les plaisirs de la table ! Mais aussi parce que les transformations hormonales de la ménopause vont favoriser la mise en réserve de graisses. Le premier antidote contre ce risque de surpoids est une activité physique suffisante et, en complément, une alimentation allégée grâce à l’élimination des calories «inutiles». À éviter ou à consommer avec beaucoup de modération : les boissons sucrées comme les sodas, les bonbons, les biscuits salés ou sucrés, l’alcool sous toutes ses formes, les glaces et les pâtisseries, les plats riches en graisses, les frites et les fritures, les sauces classiques, la mayonnaise, les sauces barbecue et tous les laitages au lait entier. Les modifications hormonales et la diminution de l’activité physique ont également pour conséquence une “fonte” progressive de la masse musculaire. Pour lutter contre ce phénomène, il y a une seule solution : bouger !
Cablul cu fibră optică a devenit foarte popular pentru interconectarea echipamentelor de rețea. Aceasta permite transmiterea datelor pe distanțe mari și la lățimi de bandă mai mari față de orice alt mediu de rețea. Fibra optică este flexibilă, da extrem de subțire și transparentă din dioxid de siliciu, nu este mai mare decât un fir de păr uman. Biții sunt codificați pe fibră sub formă de impulsuri de lumină. Cablul cu fibră optică se comportă ca un ghid de unde sau “light pipe”, pentru a transmite lumina între cele două capete cu pierderea minimă a semnalului. Analogic, gandiți-vă la cartonul unei role de hartie, având interiorul căptușit cu o oglindă și lungime de o mie de metri, și un dispozitiv laser care este utilizat pentru a trimite semnale codate, folosind codul Morse, cu viteza luminii. Cam așa funcționează un cablu cu firbă optică, cu excepția faptului că este mai mic în diametru și folosește emiterea sofisticată de lumină și tehnologii de primire. Spre deosebire de firele din cupru, cablul cu fibră optică poate transmite semnale cu mai puțină atenuare și este complet imun la EMI și RFI. Cablarea cu firbă optică este acum utilizată în patru tipuri de industrii: • Rețele ale Companiei:Fibra este utilizată pentru aplicațiile de cablare pentru backbone și interconectarea echipamentelor de infrastructură. • Rețele de Acces și FTTHFiber-to-the-home (FTTH) este utilizat pentru a asigura servicii permanente de broadbant pentru companiile mici și locuințe. FTTH suportă viteze mari de acces la Internet la prețuri accesibile, dar și telemedicină și streaming video. • Rețele Long-HaulProviderii de internet utilizează rețele pe bază de fibră optică terestră pentru a interconecta țări și orașe. De obicei, rețelele cuprind de la o duzină la câteva mii de km și folosesc sisteme de până la 10 Gb/s. • Rețele SubmarineCablurile cu fibră specială sunt utilizate pentru a asigura o viteză crescută fiabilă, soluții de capacitate mare capabile să supraviețuiască în medii dure submarine pe distanțe transoceanice. Scopul nostru este utilizarea fibrei în cadrul companiilor. Proiectarea cablului cu mediu din fibră Deși o fibră optică este foarte subțire, este compusă din două tipuri de geam și dintr-un înveliș de protecție extern. Acestea sunt: • NucleuConstă în geam pur și este partea din fibră prin care trece lumina. • ÎnvelişGeamul care înconjoară nucleul și se comportă ca o oglindă. Impulsurile de lumină se propagă pe nucleu în timp ce învelișur le reflectă. Astfel se păstrează impulsurile de lumină din nucleul fibrei într-un fenomen cunoscut ca reflexie totală internă. • IzolaţieDe obicei, o izolație din PVC protejează nucelul și învelișul. Poate conține și materiale de întărire și un înveliș al cărui scop este să protejeze geamul împotriva umezelii și a zgârieturilor. Deși este sensibil la îndoiri sub unghi ascuțit, proprietățile miezului și ale armăturii au fost modificate la nivel molecular pentru a le face foarte rezistente. Fibra optică este testată printr-un proces de fabricație riguros la o forță de minimum 100,000 livre pe inci pătrat. Fibra optică este suficient de durabilă pentru a rezista în timpul instalării și dezvoltării în condiții de mediu dure din rețelele din întreaga lume. Tipuri de Mediu din Fibră Impulsurile de lumină care reprezintă datele transmise sub formă de biți în mediu sunt generate de: • Lasere • Diode Emițătoare de Lumină (LED-uri) Dispozitivele electronice semiconductoare numite fotodiode detectează pulsurile de lumină și le transformă în tensiuni ce pot fi reconstruite în frame-uri de date. Notă:Lumina laser transmisă în cablarea cu fibră optică poate afecta ochiul uman. Trebuie să evitați să priviți în capătul unei fibre optice active. Cablurile cu fibră optică pot fi clasificate în două tipuri: • Fibră single-mode (SMF)Constă într-un nucleu foarte mic și folosește tehnologie laser scumpă pentru a trimite o singură rază de lumină. Este utilizată de obicei pe distanțe lungi care se întind pe sute de km precum telefonie pe distanțe mari și aplicații TV prin cablu. • Fibră multimode (MMF)Constă într-un nucleu mare și folosește emițătoare LED pentru a trimite impulsuri de lumină. Lumina dintr-un LED intră în fibra multimode în unghiuri diferite. Este utilizată în LAN-uri deoarece pot fi pornire prin LED-uri ieftine. Asigură lățime de bandă până la 10 Gb/s pe distanțe de până la 550 metri. Figura 1 și 2 evidențiază caracteristicile celor două tipuri de fibră. Una dintre diferențe este cantitatea de dispersie. Dispersia se referă la împrăștierea unui impuls de lumină pe o durată de timp. Cu cât este mai mare dispersia, cu atât este mai mare pierderea de putere a semnalului.
Abstract The main focus of this research is to discuss the perspective of the teamwork and its impaction organizational performance and success. Also highlight the Meanings of Team and its work sprit towards batter organizational performance and specific to its impact on the success of organization that provided the basis for this research study. In this research study a thoroughly focus was on organization and teamwork. The aim of this research is to deliver a participative view of teamwork in the organization, and also discourses the major issues and emphases on the recent work that opens the basis to move research onward. There is much worth in taking a more focus on the essential areas of teamwork. The team signifies the spirit and working capacity of the employees as team to bring organization to the success. The various explanations, definitions, processes, dimensions, team size and benefits etc. regarding the above topic teamwork and organizational success is highlighted. Keywords: Teamwork, Success, Organization, Performance, Work Groups, Employees Introduction It is indeed human beings have learned in their beginning of life to work together as (Team) that have made such a remarkable developments as unique specie. Human beings have experience throughout their social history, lived, loved, grow younger to older and worked together in groups said West M.A. (2012).The mutual social knowledge of living and functioning together creates connection among people, society and families. When work is done cooperatively as a team it can achieve extremely extra work than individually. Team can be defined as in the human society to live, to work and to play and to cooperate with others for particular task. According to John W. Newstrom et al (1993) “team is the process of assessing performance of workers, passing information and exploring methods to increase performance”. If observe closely, one can discover the instances of The Government: Research Journal of Political Science Supplementary Edition Vol. III 88 The Government social (teams) they are functioning either effectively or ineffectively everywhere; organizations, schools, work place, home etc. “Coordinating the events of people is like sand house, making by using a sole particles of sand” expressed Belbin, R. M.(2010). Moreover it is one of the general myths that the skill of team member is more important than their vigor, attention and determination for the tasks. Another widespread myth is that the team members are not alone accountable for the achievements or failures of their tasks the truth is that the members are the small parts in the teams and their individual abilities effect on the various results in team. The working relationships exist among team that might sight these relationships at different levels of involvement or relationships among the members as they move towards the degree of communication, integration and commitment increases. Terry L.G. et al (1980) expressed that “The skills are essential if members have to work together efficiently in complex situations, only development of skills and relationships, involvement on the task regarding the particular task might be selected for reaching at target that is considered as a definition of a team”. Team often perform higher when they work together with sprit that enable them to achieve a collective goal at the workplace, it is not only benefits to the organization also affects the workers confidence and success. Cooperating on various tasks reduces workloads for all team members and enables them to share duties or ideas. Work as a team is the part of everyone's life, as one is a member of a family team, staff team, school team, and community teams etc., so as to understand how to work effectively as a team member. Especially there is a need when task is threatened with increasingly many problems for example; the energy problem has effects on organization, family life, and social development and the multi-dimensional nature of many problems require a scientific skill based problem solving approach. Terry L.G, et al (1980) expressed that “The skills, competencies and efforts of team by setting priorities the team can have better impact on the problems solving such efforts can reduce work load, work duplication, and produce a result better than separate efforts”. There are some processes of teamwork by adopting those the objectives can be achieved easily. Le Pine, et al, (2008) identified10 teamwork processes that fall in three categories following are those. TEAMWORK PROCESSES TRANSITION PROCESSES •Mission analysis •Goal specification •Strategy formulation ACTION PROCESSES •Monitoring progress toward goals •Systems monitoring •Team monitoring and backup behavior •Coordination INTERPERSONAL PROCESSES •Conflict management •Motivation and confidence building •Affect management Team Work 89 Teamwork process reduces the work stress on every member which permits members to complete given important task of organization; teamwork offers members an opening to pledge with each other. Also it develops relations between the members who start a teamwork they usually sense appreciated on productive accomplishment of task. It may be cited one of the best instances of surgical team; where surgeon is assisted by his team; nurses, anesthetist and experts etc., everyone knows that their success depends upon the teamwork. In addition they are devoted to the aim that is human life it is easy to succeed with best teamwork. The important role of manager is the team building, trust building, confidence building, in the team to achieve the task. In the Situation where all team members contribute the task, it develops the positive relationship in the team that improves the trust of team members.“Functions effectively members of team must be flexible, committed, trusting each other and help to each other’s in the progress and the achievement of goals” Expressed Plamínek (2008). The accountability of every member in the team must be increased so that they do not let each other down therefore they do their best for the achievements of their teams. In contrast, working alone on a task the pressure is generally high in team in those cases of small confidence impacts fewer on members. Team consists on members who always vary from each other’s in skills, knowledge and abilities but working together that is an opportunity for them to gain skills and knowledge from each other’s that they had never before. Working alone on a task is a challenge and using the ideas of each other brings them to come up with a mutual resolution and the achievement of the task. Nowadays theoretical development and research has rested largely a new trend that is emerging within the organizations as an essential process of teamwork. Teamwork has brought a new move in the research and development to the inputs and outputs that bound, constrain and impact on the team processes within organizations said Ilgen, D.R. (1999). The world is changes fast, any one set of instructions can’t be sufficient, changes needs flexible members, teams and organizations so as to be effective on task. This paper suggests that in teams members must use the exclusive human abilities. Cannon B.et al (1995) has précised dimensions of teams into three categories: Team dimensions 1-Cognitions: include associations, task team-mate characteristics, team mission, objectives, norms, and resources, team role interaction patterns, skills, roles, and team orientation. 2-Skills: consist on adaptability, shared situational awareness and mutual concept to conflict resolution. 90 The Government 3-Attitudes: symbolize motivation, collective potency, shared vision, team cohesion, mutual trust, collective orientation and importance of. Teamsize Researchers have given different approvals about the best size of team as Katzenbachetet al (1993) suggested that the teams should comprise on a dozen or so members which are enough to achieve a task. Although seven is the best size of the team in the organizational practices said Scharf, A. (1989). Several views of researchers are expressed in the literatures and it is difficult to decide which better is because their opinions are based on their own observations. The team size matters in the proper output and performance however from an empirical research it is also difficult to decide the suitable team size and what to accept. This study suggests that team size has a practical link with efficacy such as few or many member shave impact on the performance but size matters. Proper size of team improves the performance maximum stated Campion M. A et al (1996).These different results are expected due to the fact that appropriate team size is required for task, environment and situation where team works. However, larger teams can also experience coordination problems that delay performance. Sheppard, J. A. (1993) expressed that the question of best team’s size is a complex one; more research is required on this topic to explain the impact of team size on given definite task. Literature Review Across many different organizations and industries teamwork is focused to increase the performance of employees’ their unity and also create work culture. Organizations those regularly develop new ideas or products using a project-based approach and assemble teams in order to focus responsibilities to achieve the object. Researchers have given dissimilar meanings of “teams”. Dyer W.G. (2007) said that “teams are groups of people who trust in cooperation, if members are expert the success of goal is more possible”. It is essential due to the problemsolving cooperation added from many minds of team members working on a resolution of problems. Team members contribute their thoughts together to make exclusive plans for dealing with problems and this unity enhance the result due to interaction, trust and teamwork. Teamwork means a "work done by several companions with each doing a part but all subordinating personal prominence to the efficiency of the whole" Merriam, (2012). In addition combined employees are expected less hostile to each other and accepting more of each other’s decisions. Unity of employees can increase the flow of work in organization. When employee’s working together as a team, they learn from each other that awareness is based on their personal experiences and from coworkers; Team Work 91 employees from different departments may acquire knowledge from each other. The main object for organizations is to hold the team effort to achieve output and quality; team is a key to achieve quality productivity. According to Maddux et al (2003) “some of the organizations have major benefits from the use of teamwork which are showed in the following chart: Benefits of Teamwork 1 Improving quality of work life for employees 2 Reducing absenteeism and increasing turnover 3 Increasing innovation and change 4 Improving organizational adaptability and flexibility A real team is mostly one where members are allowed to take decisions that how to complete task. That authority enables them to control the work process, decreases the outside control and increases the sense of duty for work. Team always feels superiority on workplace and they rely on each other’s being there. Plamínek (2008) said that “affiliation with teamwork gives member a sense of belonging, interaction and recognition of success”. These actions support to remove the sense of loneliness of team member in organization. Effective teams can also improve efficacy through communication and trust between the team members, quality of work and decrease in absenteeism contribute to positive impact on team. Involving employees in teamwork helps the organization remain open to new ideas.“The world of organizations is shifting individualism is out and collectivism is in, power is out, empowerment is in.” stated G. M. Parker (1998). This study discovers the experiences and difficulties of teamwork that employees and organizations are facing nowadays due to big transformation and enlarged globalization. In recent years a remarkable amendment has been emerged in the belief of team working organizations. The modern study has explored that the scope of teamwork have been appeared in system rooted in belief, and employees accept changes that denoting a modern organizational system. The organizations which are responsive to the changes appear to achieve greater satisfaction. Although it may be suggested that, the managers should assess the values and beliefs of their employees to play more dedicated role in the development of organization by making sprit to face the modern challenges. Organizational cultural is much significant and it has the excessive impact on the performance of organization and employees’ but it is quiet arguable topic that the culture of teamwork can be developed according to the requirement. It is difficult to specify the relationships and to assess the reliable set of values to use as they believed symbol across the entire organizations. This review study focus that 92 The Government there is a great influence of organizational culture on the assumptions, values, and beliefs on the individuals’ considerations, actions and performances and so is vice versa, through learning, and training process. However the researchers believe that the organizational setup aids to unite employees of diverse cultures and dissimilar social backgrounds, traditions and have their own beliefs to work. Creating a positive teamwork culture it has several diverse aspects are goal setting, conflict resolution, empowerment, ability to accomplish tasks, measuring output and consideration for other teamwork cultures stated Pack L, et al April 27, (2012). Team work in the organization delivers employees the wisdom of unity; understand to each other’s, and reducing conflict. In addition teamwork in organization inspires employee for impartiality by affirming that no one is ignored in the organization and all treated equally. It is known that a team in organization is bound and sincere to work with dedication to bring the success. If the employees are committed and recognize the teamwork values and its benefits, as a part of the organization they can contribute a lot to the achievement of organization. One can finds the informal instances of team at these level, family, society, community, tribe and work groups etc., and formally team appears at the level of departments, functional groups, and other organizational units. The employees feel a greater sense of achievement for being a part of an organization, if they attain team work, having freedom to work not forced. The system gives best performance to achieve recognition and credit from their managers and it will increase their effort that helps them to contribute the organizational performance. Each team batter knows about their role and how to achieve tasks. The true spirit of teamwork gives benefit to organization in maintaining its standard by which it becomes identified. The team defines its specialty, and the way it is doing task that is perceived by the organization as well as its managers and it is secured by appreciation. Employees identify what they believe; that exist in their belief system and those understandings call them to change their views to develop and raise attention towards batter performance. The literature contains sufficient definitions of teamwork and the word team is used to denote a set of generally developed as to learn collective values, attitudes and cooperation to work. The study praises that the teamwork is mostly related with the team success for instance, Wagner (1995) described that “in the team individual is less valued and group is more valued, with”. It is found in the study that individualismcollectivism both regulates the relationships between team size, standing, and cooperation that have better effects on the cooperation of individualists rather than the cooperation of collectivists. Team Work 93 Conclusion The main concentration of this research paper is to examine more in-depth the fundamental of teamwork and its effectiveness to achieve the organizational goals. Teamwork provides vast amounts of knowledge and information, cultural differences each of these building a culture of teamwork and the skill to make the valuable solutions of the problems. To work efficiently, team members need a good understanding of how to do their job, to achieve goal and for that a basic way to ensure understanding is training, then they have to be motivated to do a job. Team is a vital activity of organization, when organization desires to perform sound it has to be confident that team functions effectively. Consequently it is compulsory to know how team performs, what manners within a team happen, and how they make decisions. If there is knowhow of teamwork events, it can be effective for the tasks that they have to accomplish. Organizations build up their own culture through tradition, history and structure these values can be accepted by team workers of an organization. The values and assumptions are the vital tools of organizations and are used as guidance for team. These have to do mostly with the basic dignity and worth of all members of team and the ability, necessity for them to solve the problems and work for the positive change. Through this review study is concluded that there is a good impact of teamwork on the organizations doings and success. Subsequently in recently developed literature there is a great focus amongst the social scientists and scholars’ in their discussion on the above topic teamwork. The above study is also an evidence of little effort to assess the significance of teamwork in organizations success. teams in organiz
