The Analysis of Conduction Plan of New Employees:An Empirical Research of TK3C

Chen, Guan-Hung 30 June 2004 (has links)
While an enterprise is from the initiative to the growing phase, it is necessary to expand the scale to meet the dramatically upside and the market demand. However the existing human resources are not efficient anymore so it is inevitable to increase the staff to reflect the growing organization. In the view of the above scenario, how to create an appropriate recruitment and the selecting system for the company? We could see that some newcomers will easily be nervous , and anxious or even will quit soon due to the problem of getting with the new environment and job. Therefore how the organization makes the new employees fit the company smoothly through the socialization plan for the employees becomes an important issue which influences the growth of the enterprise. The purpose of this research is to analyze the socialization plan of the enterprise as following item: 1. How to recruit able people who suit the company. 2. How to make them fit the company smoothly and show the outstanding performance. 3. Reduce the turnover of the employee for not fitting for the organization.TK3C is the target in this research. We focus on its plan of recruiting, selecting and training program for the entry of Great China market. In this case we can observe a growing company and its expansion plan of recruitment. Also the case evaluation and the improvement plan are included. The study was done with field research way--practical training, interview with the related staff who makes effect the project, and observing the design and the effective of the company installation plan. In addition, the related theory of the socialization is collected for being the basis of the analysis and inspection. Some major problems were found during the research such as the affect of the recruitment is weaker and weaker, no clear and specific standard, invisible effect on the training. There are suggestions and improvement plan in this research. After the approach of constructive interview and the apprenticed- training, hopefully we could see the overall performance of the employees will be increased and the turnover ratio of the newcomer will be decreased.

Studies on conducting polymers

Mohammad, F. January 1987 (has links)
This thesis reports studies of several aspects of the behaviour of intrinsically conducting organic polymers with conjugated backbones. Polyparaphenylene has been synthesised by a range of chemical methods and the products studied by spectroscopy, x-ray diffraction and electrical properties. It is shown that the properties of the polymer are sensitive to the method of synthesis. The intrinsic and oxidative degradation of compensated and p-type doped poly thiophene and polypyrrole have been studied by uv-vis, ftir, tga and by monitoring electrical conductivity. Dissimilar degradation behaviours of the two polymers have been rationalised in the light of the ionisation potentials of the polymers and the chemical nature of their repeat units while comparing with other polymers such as polyacetylene, polymethylacetylene and polypropylene. Studies on poly thiophene and polypyrrole show that these polymers are much more stable than polyacetylene but still undergo degradation reactions which involve two steps viz. loss of dopant and then degradation of polymer backbone. The general features of their degradation mechanisms are discussed. Thin films of p-type doped poly thiophene were found to react ~apidly but irreversibly with ammonia and water whereas the loss of conductivity was largely reversible by evacuation in polypyrrole. The interaction between compensating agents such as ammonia, water and butyl lithium with p-type doped poly thiophene and polypyrrole has been examined and chemical reaction schemes have been proposed with a possiblility of their use in sensing devices. The diffusion of dopants into and out of poly thiophene and polypyrrole along with its dependence on temperature and dopant concentration in the polymer, has been studied by a galvanostatic pulse method. The Arrhenius plots show two distinct but fairly linear regions of low and high activation energies with a transition at 273K. An increase in diffusion coefficients in the order of N(But)4+ BF4- <Na+CI04- <Li+AsF6- has been observed. It is proposed that the ionic size is a limiting factor. These results are discussed in terms of potential applications of these polymers.
