In Taiwan, residential businesses is one of the most important supports for the city economy, and that¡¦s why it has gained the reputation of the leader of the industry. Its rises and falls will influence the living quality of the people as well as the general economy of the city. Hence, residential businesses is the key factor for economic rebuilding. The government has adopted various measures to promote ¡§City Vitalization¡¨. However, these policies were invalid due to the change of the industrial types, the migration of the traditional industry, and the increase of the unemployment, which have led to the price drop in real estate. According to the 2002 residential survey, there are 499,429 houses in Kaohsiung with a 16% vacancy rate. In other words, there are 82,275 vacant dwellings. This research was conducted because China and Taiwan have become the members of the World Trade Organization¡]WTO¡^ in 2001 and 2002 respectively, which would substantially liberalize the so-called ¡§three-links¡¨ policy. In practice, it will increase the international trade opportunities for both sides of Taiwan Straits. Direct flights are a virtual certainty. The negotiations on air ties will set a brand-new situation. When it comes to direct flights, Taiwan government holds ¡§Kaohsiung is before Taipei¡¨ policy. Therefore, The Kaohsiung International Airport will be the top priority. Consequently magnificent commercial opportunities will be brought and undoubtedly benefit the residential property. Nominal Group Technique¡]NGT¡^ is a way of organizing a meeting to enhance its productivity. Its purpose is to balance and increase participation, to use different processes for different phrase of creative problems solving and to reduce errors in aggregating individual judgments into group decisions. It is especially useful for problem identification, problem-solving and program planning. For gathering various opinions, researchers have attended NGT meetings twice, conducted a questionnaire, and interviewed experts and the conclusions are described as follows:Kaohsiung, located in the southern part of Taiwan, is not only the biggest commercial harbor and the second largest city in Taiwan, but also the chief center of the heavy industry. If the government could improve its image and investment environment to attract foreign businessmen and capital, its real estate would boom again. As the reason mentioned above, Kaohsiung government should actively participate in talks on the issue of ¡§three links¡¨ and request Beijing to put forth concrete strategies to promote collaboration between both sides of the Taiwan Straits for a win-win relationship.

Abstract Human resource is the most valuable and prominent property to a company. No matter in what aspect, human resource is fundamental to the development and implementation of programs and plans to support the overall growth of the company. Hence, how to find the most competent employees through proper sources is what the business entity needs to consider about. The sources to find qualified employees include human resource website, newspapers, schools, governmental agencies for employment services, employment exhibition, referral, and transition. Reviewing the past researchs of human resource, most of them focus on recruitment and staffing, but few to deal with referral employment. However, in Taiwan where interpersonal relationship is highly valued and recommended, the recruitment of employees through referral is very common. Therefore, this research aimed at the referral. Furthermore, the research also aimed to find out in what kind of relationship between the referral and introducer, the referral would have a preferable and better performance. Would the same working experience with the present job that referrals had serve as a critical variable affecting the performance? The results reveal that the turnover rate of referral is much lower than those hired personnel through other sources. Referrals generally have better performances at work when they were co-workers with the introducers in their former jobs. The finding also shows that referrals also have better performance when they came from the related industries related to the present jobs. Key words : performance , recruiting sources, referral, turnover rate

There are two aspects in this study: cylinder penetrations and XBP (Expendable Bottom Penetrometer) interpretations. The cylinder studies firstly investigate the relationship between the soil resisting force and penetration depth by a series of rateindependent finite element analyses of pre-embedded penetration depths, and validate the results by upper and lower bound solutions from classical plasticity theory. Furthermore, strain rate effects are modeled by finite element simulations within a framework of rate-dependent plasticity. With all forces acting on the cylinder estimated, penetration depths are predicted from simple equations of motion for a single particle. Comparisons to experimental results show reasonable agreement between model predictions and measurements. The XBP studies follow the same methodology in investigating the soil shearing resistance as a function of penetration depth and velocity by finite element analyses. With the measurements of time decelerations during penetration of the XBP, sediment shear strength profile is inferred from a single particle kinetic model. The predictions compare favorably with experimental measurements by vane shear tests.

In this work, we focus on two important goals of the transmission of scalable video over the Internet. The first goal is to provide high quality video to end users and the second one is to properly design networks and predict network performance for video transmission based on the characteristics of existing video traffic. Rate-distortion (R-D) based schemes are often applied to improve and stabilize video quality; however, the lack of R-D modeling of scalable coders limits their applications in scalable streaming. Thus, in the first part of this work, we analyze R-D curves of scalable video coders and propose a novel operational R-D model. We evaluate and demonstrate the accuracy of our R-D function in various scalable coders, such as Fine Granular Scalable (FGS) and Progressive FGS coders. Furthermore, due to the time-constraint nature of Internet streaming, we propose another operational R-D model, which is accurate yet with low computational cost, and apply it to streaming applications for quality control purposes. The Internet is a changing environment; however, most quality control approaches only consider constant bit rate (CBR) channels and no specific studies have been conducted for quality control in variable bit rate (VBR) channels. To fill this void, we examine an asymptotically stable congestion control mechanism and combine it with our R-D model to present smooth visual quality to end users under various network conditions. Our second focus in this work concerns the modeling and analysis of video traffic, which is crucial to protocol design and efficient network utilization for video transmission. Although scalable video traffic is expected to be an important source for the Internet, we find that little work has been done on analyzing or modeling it. In this regard, we develop a frame-level hybrid framework for modeling multi-layer VBR video traffic. In the proposed framework, the base layer is modeled using a combination of wavelet and time-domain methods and the enhancement layer is linearly predicted from the base layer using the cross-layer correlation.

When employee turnover rate in a company is too high, not only it will result in the increase of cost, affecting employee morale, making negative impression on customers, but also impacting corporate performance in the long run. This research uses one of the qualitative research techniques to study the human resource management practices of the four interviewed companies, trying to identify the best practices they have in common that contribute to the decline of employee turnover rate or maintain it within acceptable level. After interviewing the four companies, two in service industry and the other two in high-tech manufacture industry, this research analyzed their human resource management practices, and found five best practices they have in common that help these four companies successfully keep employee turnover rate in control. Therefore this research concluded that a company, whether it is in service industry or high-tech manufacture industry, or whether its organizational culture is more performance-oriented or rather paternalistic, by recruiting employees through diversified approaches and selecting them by their personalities, and strongly linking performance appraisal system, reward system, promotion system and training and development system together, the synergy of the best practices all together will contribute to the decline or maintain of employee turnover rate.

This study investigates sub 200nm half-pitch polymer structures by nanoimprint process. The trench structures were fabricated on quartz glass with various depths and widths by FIB. To investigate the best nanoimprint process on SU-8, we studied various parameters such as: imprinting temperature, imprinting pressure, and temperature for de-molding, etc. ¡@This study had successfully defined 50nm width with different depths on to SU-8 by imprint. ¡@Imprint temperature above Tg 30¢J with constant pressure on continuous impressing and de-mold in room temperature would result in better imprinting results. The filling rate of this nanoimprint technology was measured by atomic force microscopy. ¡@For structures above/near 100nm half-pitch, the filling rate is nearly 100%.

The topics of this study are as follows: (a) Poly(butylene succinate) (PBSu) rich random copolymers containing ~20% and ~50% trimethylene succinate (TS), PBTSu 80/20 and PBTSu 50/50 that were synthesized from 1,4-butanediol, 1,3-propanediol and succinic acid: The influence of minor TS units on the thermal properties and crystallization rate of PBSu was investigated. (b) Random copolymer of ~90% PBSu and ~10% poly(1,4-cyclohexanedimethylene succinate), PBCHDMSu 90/10, that was synthesized from 1,4-butanediol, 1,4-cyclohexanedimethanol and succinic acid: The influence of cyclohexene unit on the thermal properties and crystallization rate of PBSu was investigated. (c) Blends of PBSu and poly(trimethylene succinate) (PTSu) or poly(ethylene succinate) (PESu): The weight ratio PBSu and PTSu (or PESu ) were 1:1. The crystallization and morphology of blends (PBSu/PTSu 50/50 and PBSu/PESu 50/50) were investigated and compared with PBTSu 50 and PBESu 50/50. The chemical composition and the sequence distribution of co-monomers in copolyesters were determined using NMR. Thermal properties of polyesters and blends were characterized using differential scanning calorimeter (DSC) and temperature-modulated DSC (TMDSC). The crystallization kinetics and equilibrium melting temperature were analyzed with Avrami equation and Hoffman-Weeks linear extrapolation. The thermal stability of polyesters was analyzed by thermogravimeter (TGA) and polarized light microscope (PLM) under nitrogen. Wide-angle X-ray diffractograms (WAXD) were obtained for specimens after complete isothermal crystallization. The growth rates, regime transition temperature, morphology and phase separation were studied using polarized light microscope (PLM) with isothermal method or nonisothermal method. The morphology of specimens after chemical etching were investigated using atomic force microscope (AFM) and scanning electron microscope (SEM). The distribution of butylene succinate (BS) and TS units in PBTSu 80/20 was found to be random from the evidence of a single Tg and a randomness value close to 1.0 for a random copolymer. With the increasing of minor amounts of comonomers, the sequence length of butylene succinate decreases, and the crystallization rate and the degree of crystallinity drop. DSC heating curves of isothermal crystallized PBTSu 80/20 and PBCHDMSu 90/10 showed triple melting peaks. Multiple melting behaviors indicate that the upper melting peaks are associated with the primary and the recrystallized crystals, or the crystals with different lamellar thickness. As the Tc increases, the contribution of recrystallization slowly decreases and finally disappears. Hoffman-Weeks linear plots gave an equilibrium melting temperature of 113.5

This study contains four main parts. Part 1, poly(butylene succinate) (PBSu) rich random copolymers containing ~20% 2-methyl-1,3-propylene succinate (MPS), PBMPSu 80/20. The influence of minor MPS units on thermal properties and crystallization rate was investigated. Part 2, poly(butylene succinate) (PBSu) rich random copolymers containing ~5% 1,4-cyclohexanedimethylene succinate (CHDMS), PBCHDMSu 95/5. The influence of cyclohexane unit on thermal properties and crystallization rate was investigated. Part 3, Poly(butylene succinate) (PBSu) random copolymers containing ~50% 2-methyl-1,3-propylene succinate (MPS), PBMPSu 50/50. Blend of PBSu with poly(2-methyl-1,3-propylene succinate) (PMPSu). The weight ratio of PBSu and PMPSu were 1:1. The crystallization behavior and morphology was compared. Part 4, Poly(ethylene succinate) (PESu) random copolymers containing ~50¢H trimethylene succinate (TS), PETSu 50/50. Blend of PESu with poly(trimethylene succinate) (PTSu). The weight ratio of PESu and PTSu were 1:1. The crystallization behavior and morphology was compared. Molecular weights of copolymers were measured using capillary viscometer and gel permeation chromatography (GPC). The results indicate that polyesters used in this study have high molecular weights. The chemical composition and the sequence distribution of co-monomers in copolyesters were determined using 1H NMR and 13C NMR. The distribution in these copolyesters was found to be random from the evidence of a randomness value close to 1.0 for a random copolymer. Thermal properties of blends and copolyesters were characterized using differential scanning calorimeter (DSC) and thermogravimeter (TGA). The crystallization kinetics and mleting behaviors was analyzed after isothermal crystallization by DSC. Wide-angle X-ray diffractograms (WAXD) were obtained for specimens after complete isothermal crystallization. The growth rates, morphology were studied using polarized light microscope (PLM). The morphology of specimens after chemical etching was investigated using scanning electron microscope (SEM) and atomic force microscope (AFM). AS the ratio of MPS units increase, the degree of crystallinity and crystallization rate drop, it was due to decrease of butylene succinate sequence length. The spherulite growth rate of PBCHDMSu 95/5 is much slower compare with PBSu rich copolymers containing 5% TS or MPS. It was due to the steric effect of cyclohexane unit in the polymer chains. The crystalline morphology of PBMPSu 50/50 and PETSu 50/50 were quite different. It was due to the short sequence length of butylene succinate and ethylene succinate. From the analysis results by DSC and observation by PLM and SEM, it indicates that PBSu was miscible with PMPSu while PESu was partial miscible with PTSu.
