I try to point out the relationship among job interest, leadership, job satisfaction and turnover intention in public relations industry. Because of long working hours, heavy strain and the unbalanced repay, turnover rate is unusually high. However, in this situation, there are still someone willing to work in public relations industry. What are the reasons urge them to stay? What are the key factors effect their job satisfaction? The research exploits questionnaire to reach the target objects and adapts cronbach¡¦s £\ , Independent-Sample T Test , One-Way anova , Pearson correlation and linear structure relation to analyze the collecting data. Through real case investigation, there are some results in this research. 1.The LMX is higher , the job satisfaction of member is higher. 2.The job characterstics of member is better , the work motivation is higher. 3.The work motivation is higher , the job satisfaction is higher. 4.The job satisfaction is higher , the turnover intention is lower. Considering the research , we believe that the employees , willing to put himself to work in public relations industry , have high achievement motivation . It drives them flinging themselves into this industry and ignoring the unbalanced repay , just because of the fancy to the job. However , motivation needs to be encouraged and satisfied, employee with high achievement motivation don¡¦t certainly have high performance or job satisfaction. Each member judge whether his job is interesting on his own mind, and his judgement affects his performance and job satisfaction. The job characteristic judged by people encouraged his job motivation, and then affects his job satisfaction positively. By the way, the member with high LMX gets more concern and support , it raise his job satisfaction again.

Abstract This study aims to investigate the influence of micrometeorology on atmospheric visibility in Taipei Basin by carrying on routine and intensive visibility observation, analyzing particle concentrations and size distribution, monitoring atmospheric optical coefficients of particles, and collecting meteorological conditions (wind direction, wind speed, temperature and humidity). Based on the information of the broad view of the meteorological parameters from 1998 to 2005, the air pollution episode in Taipei Basin mainly occurred during the winter periods accompanied with the weather patterns of high pressure outflow style I, high pressure outflow style II or circus-sluice of high pressure outflow. Based on the collected visibility data from Taipei of Central Weather Bureau for the past 21 years (1983~2004), it shows the visibility increasing each year. The visibility seasonal variation was also observed higher than that during winter. The mean visibilities from Tamsui, Songshan, and Sindian directions are 10.54 km , 9.72 km and 8.62 km, respectively. In general, the visibility from the Tamsui direction is slightly higher than those the from two directions, This result shows visibility is influenced not only the pollution factor and meteorological factor, but affected by the local topography. Our study revealed that the visibility data leads on the Tamsui, Songshan obserrative directions is better. Two intensive sampling campaign were conducted during August 15~22 of 2004 and January 15~22 of 2005 on the roof of Taipei County Government, respectively. The results showed mass concentration of particulate matter in winter is higher than that in summer. A bi-mode size distribution of aerosol particles was also observed in the Taipei basin. Two peaks of aerodynamic diameter of PM were observed at 0.56~1.0 µm and 3.2~5.6 µm, respectively. In addition, extinction coefficient is always high during winter. Mean scattering coefficient is about 80~108 Mm-1 while the mean absorption coefficient is around 9~35 Mm-1, during the 1st intensive sampling period. Mean scattering coefficient is about 101~119 Mm-1 while the mean absorption coefficient is around 16~64 Mm-1, during the 2nd intensive sampling period. Our study also shows that visibility has a higher correlation with fine particles(R=0.70~0.96) than that with coarse particles(R=0.045~0.629). Hance, visibility is affected mainly by fine particles. In general, the intensive observation of visibility also shows that in summer the visibility is higher than that in winter. In addition, the analysis from MM5 shows that the visibility for the Tamsui direction is usually influenced by the prevailing wine direction, It is because of that northwestern from sea brings lots of water spray into the basin. This spray water will increase the particle diameter and cause the increasing of extinction coefficient. It will also impair the visibility.

Based on the trend of dividend payout ratio from 1986 to 2004 in Taiwan, it appears the companies have experienced two different stages of cash dividend policies. Before 1997, the cash dividend payout ratio declines slowly. But starting 1998, the payout ratio raises substantially, and the sum of cash dividend appears the same trend. Investigate the companies that pay cash dividend out, discover that they concentrate on those make a earning, and focus on those have high profit year by year. The sample is selected from listed companies in Taiwan Stock Market from 1988 to 2004 , not including financial and utility companies. This thesis uses binary logistic regression to test the relationship between company¡¦s characteristics and paying cash dividend, and survey whether this characteristics are the reason to make the cash dividend payout ratio raises quickly. The result of this research found that there is positive relationship between the payout of cash dividend, the company size, profitable ability, and free cash flow ratio. Moreover, there is negative relationship between the payout of cash dividend, growing opportunity, and liability ratio. But among the two variables measuring the growing opportunity, the asset growing ratio has a better interpretation in the earlier stage; and the market-to-book ratio does in the later stage. On the base period of 1988 to 1997, use binary logistic regression and portfolios to set up a model to fit the cash dividend policies. The overall empirical evidence implies the company¡¦s characteristic don¡¦t change the companies¡¦ tendency of paying cash dividend. In other words, the phenomenon of cash dividend payout ratio raising actually is caused by the increasing fundamental tendency of the sample companies paying cash dividend.

Soil suction is one of the most important physical variables affecting the soil engineering behavior, moisture content. Suction has a major controlling influence on soil shear strength. The moisture diffusivity properties of unsaturated properties of soils exert a critical influence on the depth to which seasonal variations of moisture and suction at the ground surface extend into the soil mass. Hence, a study of moisture diffusion coefficient is pivotal. In this research the drying test originally proposed by Mitchell (1979) has been validated by back calculating the moisture diffusion values using the empirical relation established by Lytton (2003). The non-linear flow through unsaturated soils has been simplified to a linear problem for simplicity in this study. Owing to this simplification, certain refinements have therefore been applied in the determination of diffusion coefficient. Thermocouple psychrometer was used to measure the soil suction along the length of the sample and at different times in the laboratory. Initial suction measurements were done using the filter paper test. Curve fitting procedure established by (Aubeny and Lytton, 2003), has been used for the determination of the diffusion coefficient. Analytical validation of the moisture diffusion coefficient, required coefficient of permeability, ??k??, slope of suction water characteristic curve ??S?? and air entry value ??ho?? as the major input parameters. Mitchell (1979) assumed the value of ??ho?? to be 100 cm. In this research air entry value, ??ho?? has been re-evaluated and it comes out to be higher than the pre estimated value. The value of slope of suction water characteristic curve, ??S?? obtained from pressure plate tests, compares well to the empirical equation of Lytton (2003). The results of moisture diffusion coefficient obtained from the empirical equation come out in the same range as obtained from the refined Mitchell??s (1979) drying test. The refinements includes introduction of constant temperature environment. Owing to the least variation in temperature, more reliable and reproducible data was obtained. The range of moisture diffusion coefficient, ??-values obtained from empirical equation, comes out to be coherent with the laboratory data. Hence, it can be concluded that the research was successful.

¡@¡@Currently, The Cr-doped fibers are grown by LHPG method or drawing-tower technique. The Cr-doped YAG preform was firstly fabricated by a rod-in-tube method. We have successfully fabricated the Cr-doped fibers by using a commercial drawing-tower technique. By employing a negative pressure control in drawing-tower technique on the YAG preform, the Cr-doped fibers with a better core circularity and uniformity, and good interface between core and cladding were fabricated. The core non-circularity was smaller than 3%, the spontaneous emission spectrum showed the bandwidth that approach to 300 nm, and the output power density level have promoted to a few nW/nm. ¡@In this study, we focused on the analysis of dynamic fluorescent characteristics of Cr-doped fibers in order to improve the quality effectively. The lifetimes of Cr4+ fluorescence and concentration of Cr ions were 1.5 £gs and 510 £gg/g, respectively.The concentration of the Cr ions was less than the Cr-doped fibers grown by LHPG method. The high-resolution micrograph showed that there was nano-crystalline structure in the core surrounded by SiO2 amorphous matrix. These nano-particles gathered at the core and formed micrometer clusters, and therefore resulted in high scattering loss around 1.17dB/cm. ¡@¡@In order to improve the Cr-doped fibers quality, reduce propagation loss, and promote the spontaneous emission power density. We have to decrease the temperature and drawing speed in the drawing process Therefore, the new Cr-doped fibers may have the potential for being used as a new generation broadband fiber amplifier to cover the bandwidth of the entire 1.3-1.6 £gm range which exhibit 300 nm usable spectral bands.

The trend of low-birth rate is a crisis for schools to run. Especially for the schools, the doomed disadvantaged ones, in off-shore islands in Penghu County, an archipelagic county in Taiwan, to be closed or merged could be a huge barrier for the education-development. Therefore, to think out the development model of characteristic schools, and make use of the advantages of the small-scale in schools and classes to combine the special natural environment and cultural historical resources, and then construct a special and innovation regional program in order to increase the value of education and operate marginal profits.

<p>Research in the area of bridge design has been and still isconcentrated on the study of the strength of materials andrelatively few studies have been performed on traffic loads andtheir effects. Traffic loads have usually been assumed to begiven in codes. This is mainly because it is very difficult tomodel traffic loads in an accurate manner because of theirrandomness.</p><p>In this work, statistical evaluations of traffic loadeffects, obtained from real as well as Monte Carlo (MC)simulated vehicle data, are presented. As the dynamiccontribution of the vehicle load was filtered by the systemused for measuring vehicle weight, no attention was paid in thepresent study to the dynamic effects or the impact factor. Thedynamic contribution of the traffic load models from codes wasdeducted wherever they were compared with the result from theevaluation of the real data. First, the accuracy of thecollected data was investigated. This was done to examine theinfluence of what was most probably unreasonable data on thefinal evaluated results. Subsequently, the MC simulationtechnique, using a limited amount of the collected data, wasused to generate fictitious vehicle data that could representresults from field measurements which would otherwise have tobe recorded under a long period. Afterwards, the characteristictotal traffic loads for bridges with large spans weredetermined by probabilistic analysis. This was done using realas well as simulated data and the two were compared. Theseresults were also compared with the corresponding valuescalculated using the traffic load model from the Swedish bridgedesign code.</p><p>Furthermore, using traffic data, different load effects onbridges (girder distribution factor of slab-on-girder bridgesand the mid-span deflection as well as the longitudinal stressat critical locations on box-girder bridges) were investigated.The main task was to obtain a more accurate knowledge oftraffic load distributions on bridges as well as their effectsfor infrastructure design. The results showed that the trafficload models from codes gave considerably higher load effectscompared to the current actual traffic load effects. Theseinvestigations were based on the available data for the actualposition of the vehicles on a single bridge and might not coverall possible traffic scenarios.

The family of stable distributions represents an important generalization of the Gaussian family; stable random variables obey a generalized central limit theorem where the assumption of finite variance is replaced with one of power law decay in the tails. Possessing heavy tails, asymmetry, and infinite variance, non-Gaussian stable distributions can be suitable for inference in settings featuring impulsive, possibly skewed noise. A general lack of analytical form for the densities and distributions of stable laws has prompted research into computational methods of estimation. This report introduces stable distributions through a discussion of their basic properties and definitions in chapter 1. Chapter 2 surveys applications, and chapter 3 discusses a number of procedures for inference, with particular attention to time series models in the ARMA setting. Further details and an application can be found in the appendices. / text
