Abstract On June 23, 2009, the Ministry of the Interior approved the proposal of Kaohsiung County and City to merge. The merger of Greater Kaohsiung Municipality which will take place on December 25, 2010 has finally been actualized after 20 years of waiting for Kaohsiung residents. The merger of Kaohsiung County and City will have a positive influence on regional development and competitive strength. The population will reach 2,770,000 with an area of 2,946 square kilometers after the merger. This merger will endow Greater Kaohsiung with substantial strength to compete with other cities in the world. At present, Kaohsiung City is unable to further develop its transportation systems due to insufficient land, although it already possesses a convenient traffic network consisting of an international harbor and airport, the high-speed rail, Kaohsiung Rapid Transit System and Taiwan Railways. Fortunately, Kaohsiung County possesses extensive land, industrial foundations and abundant natural resources. The integration of Kaohsiung City and County will empower the development of Greater Kaohsiung. As the merger of Kaohsiung County and City has been approved, the aim of this study is to examine how real estate developers and people who are fond of purchasing leisure cottages with the rural landscape make good use a new setting and conditions after the merger, to develop and/or select ideal leisure cottages with the rural landscape in terms of a convenient traffic network, the picturesque landscape, and a superior geographical environment based up a reasonable price, extensive leisure facilities and other criteria. The study provides real estate developers with an understanding of selection criteria in leisure cottages with the rural landscape through the ranking of seven factors (quality control, price, convenient transportation network, geographical environment, leisure facilities, landscape and cottage characteristics) by discussing three selected construction projects of leisure cottages with the rural landscape located in Greater Kaohsiung (He Fong Ting, Meinung-Moonlight Villa and Da Kuai Shan Hu). The respondents include: 1) three government officials: Mr. Jhong-Yuan Su, Deputy Director-general of Tourism & Traffic Department of Kaohsiung County; Mr. Siao-Jhih Yang, Chief of Agriculture Section of Meinung Township Office; and Mr. Wun-Hao Wu, Board Director of Landscape Engineering Association of Kaohsiung City; 2) three industrial representatives: Mr. Jin-Tong Lin, President of Moonlight Villa; Mr. Cing-Rong Chen, President of Ever Top Construction of Developing Enterprise; and Mr. Jin-Chih Wang, Project Manager of Meinung Cing Jing Villa; 3) three academic representatives: Mr. Sin-Jing Huang, Chairperson of Department of Horticulture, National Chiatung Agricultural Vocational Senior School; Mr. Lian-Bao Chen, Instructor of Department of Sport, Health & Leisure, Cheng Shiu University; and Architect Mr. Wei-Jhe Chen; 4) three consumer representatives for each of three selected construction projects in Greater Kaohsiung. A total of 18 respondents from four categories receive an in-depth interview to collect qualitative and quantitative data to analyze and to further understand the selection criteria on developing leisure cottages with the rural landscape in Greater Kaohsiung.

Abstract Dental implants can be a breakthrough in dental treatment. It has become an important index of the operation performance for the dental clinics. Patients¡¦ knowledge of dental implant medical quality is different from dentists¡¦ due to asymmetric information. This study sample consists of two major groups: 200 patients and 20 dentists, recruited from 15 dental clinics providing services of dental implants in Kaohsiung city. The data was collected by a questionnaire and try to investigate the relationship between the baseline data , the knowledge and attitude of patients about dental implants. The purposes of this study is to identify the difference between patients and dentists about dental implant medical quality . Providing information for patients seeking dental implant care, and for dental implant marketing of dental clinics. The results show that the willingness to accept dental implants is higher in patients well-educated and good oral hygiene . The most popular resources of getting dental implant information are from TV and their dentists. 74% of patients do not know the brand of their dental implants. 84.2% of patients would like to recommend dental implants with the reasons of their dental experiences and the trust of the dentists. The satisfaction rate of dental implant exceeds 70%. As for selecting dentists, medical skills, medical ethics, medical equipments and public praise are the more important factors. Male and young patients are more affected by objective factors; female patients take more consideration of their own feelings. However old patients more concern about interpersonal relationship. Highly-educated patients attach more importance of profession; Lowly-educated patients more care about the environment of the clinics. About medical quality, the most important factors in dentists are medical skills and sterilization, followed by dentist-patients relationship. The first three in patients are medical skills, sterilization and specialist certification. Of all six common factors in patients and dentists, the most different factor is dentist-patient relationship. It shows obviously high in dentists, and it maybe due to the elevation of consumer¡¦s awareness in Taiwan. Key word: dental implant, dental service quality , dental clinic choice, factor analysis

In recent years, many construct wetlands in Taiwan have been built for the purposes of wastewater treatment, river water purification, and ecology conservation. To evaluate the effectiveness of constructed wetlands on water purification, frequent water quality monitoring is needed. In this study, the multivariate statistical analysis was applied to evaluate the contaminant removal efficiency in a constructed wetland, and the time series method was then used to predict the trend of the indicative pollutant concentration in the wetland. Multivariate statistical analysis simplifies the original data into representative factors, or hive off the similarity between data to cluster, and then identify clustering outcomes. In this study, an artificial wetlands at the site around an old bridge locates at the Kaoping River Basin was used as the study site. The statistical software SPSS 12.0 was used to perform the multivariate statistical analysis to evaluate water quality characteristics of its. Results from this study show that the removal efficiency for the total coliforms (TC) of System A and B was 98%, 55% for biochemical oxygen demand (BOD), 53% for chemical Oxygen demand (COD), 55% for ammonia nitrogen (NH3-N), and 39% for total nitrogen (TN). Moreover, suspended solids (SS) couldn¡¦t be removed in both A and B systems. The box-and-whisker plot indicates that the water quality of inflow was unstable and variable; however, outflow was turning stable with its flow direction. The major pollutant indicators, except SS, were all in a decreasing tendency. The paired t-test shows p value of each item were lower than 0.05, except total phosphorus (TP) in System A, nitrate nitrogen (NO3-N) and Chlorophyll a (Chl-a) in System B. The correlation parameters from TN, nitrogen oxides (NOx), NO3-N and nitrite nitrogen (NO2-N) and so on were all higher than 0.7. The factor analysis of SPSS shows that 17 water-quality items of the study site could obtain four to six principal components, including nitrate nutrition factor, phosphorus nutrition factor, eutrophication factor, organic factor, and environmental background factor, the major influencing components are nutrition factor and eutrophication factor. The ponds of the study site were classified into two or three clusters depend on in-and-out flow location. This study attempted to establish a forecasting model of wetland pollutants concentration through the time series (ARIMA), results show that the outcome of the B7 pond was better than others. Results indicate that the ARIMA model can be used to simulate the trend of treatment efficiency using the wetland system. Experience and results obtained from this study would provide solutions for water quality control.

The main purpose of this research was to analyze the distribution and accumulation of metals in sediment cores of Gao-ping Canyon nearby areas. Enrichment factor (EF) and Sediment Quality Guidelines (SQGs) were also used to assess the pollution history, sources and extent of heavy metal pollution. The results revealed that copper and cadmium metal concentrations have not been contaminated significantly; while zinc and lead concentrations reached moderate degree of pollution, which exceeded guidelines of Low-SLG in Ontario and ERL in NOAA. The concentration of lead was higher than most found in Taiwan. Although chromium was found mild polluted, but attention should still be paid as those concentrations exceeded the values of Low-SLG¡BSevere-SLG and ERL. Comparing results from cores in Southern and Northern shelves of Gao-ping Canyon, the trend of heavy metal concentrations in Northern shelf rose gradually but had an apparent downward trend in surface mixed layer; while distinct variation with time was observed in Southern shelf.

The emission of polycyclic aromatic hydrocarbons (PAHs) from the diesel engine on a dynamometer by mixing ratio of the fuel (H2/O2 /diesel) was investigated. The engine was operated at a one load steady-state condition of 1,600 rpm with torque and power outputs of 145 Nm and 24.5 kW. In this condition, the measurement of the mixing ratio of the fuel (H2/O2 /diesel) was first recorded without any induction of H2/O2 mixture (Base) into the engine. Then, seven flow rate levels of H2/O2 mixture were used by 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min, and 70 L/min, respectively. The concentrations of total PAHs were 106.58, 101.89, 95.30, 90.70, 85.98, 82.35, 72.38, and 67.30 £gg/m3, respectively for Base (0 L/min), 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min, and 70 L/min of H2/O2 mixture. The emission factor of total PAHs were 6.00, 5.73, 5.36, 4.99, 4.84, 4.50, 4.07, and 3.78 mg/bhp-hr, respectively for Base (0 L/min), 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min, and 70 L/min of H2/O2 mixture. The removal rate of total PAHs were 4.4%, 10.6%, 14.9%, 19.3%, 22.7%, 32.1%, and 36.9%, respectively for 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min, and 70 L/min of H2/O2 mixture. This result showed using H2/O2 mixture significantly reduced emissions of PAHs. As the regulated harmful matters, using H2/O2 mixture, CO¡BCO2¡BTHC and PM decreased, whereas the NOx emission increased. The energy saving of the fuels (H2/O2 /diesel), the total oil equivalents combined by fuel consumption of diesel engine and electricity consumption of H2/O2 generator, were 2.42, 2.49, 2.50, 2.48, 2.51, 2.35, 2.18, and 2.17 for Base (0 L/min), 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min, and 70 L/min of H2/O2 mixture. The result showed that reduced saving energy of the fuel (H2/O2 /diesel) by 3.2% for 50 L/min, 9.8% for 60 L/min, and 10.4% for 70 L/min, respectively.

This research carries out all tests in diesel engine takes neat diesel and hydrogen+oxygen (H2/O2) which is used as an additive (H2/O2 mixture: 10 to 70 L/min, interval 10 L/min) in a stable state condition (engine was operated at one load steady-state condition of 1600 rpm with torque and power outputs of 145 Nm and 24.5 kW, respectively). Characteristics of carbonyls emissions from H2/O2 as an additive were investigated in a HDDE (heavy-duty diesel engine) and compared with those from neat diesel, contains the concentration, emission factor and elimination efficiency, whole of change tendency in order to help the understanding of diesel engine pollutant emissions, and appraises energy conservation of benefit which add to H2/O2. The regulated pollutants emission, using H2/O2 mixture (10 to 70 L/min), THC, CO, CO2 and PM emission all increased while H2/O2 showed signs of decrease; on the contrary, NOx emission increased while H2/O2 increased. Regarding Carbonyls emissions, the total carbonyls concentration of diesel engine take neat diesel was 3218.02 £gg/m3 and the emission factors for diesel engine take neat diesel were 180.882 mg/bhp-hr and 788.061 mg/L-fuel, respectively. When H2/O2 mixture was added, total carbonyls concentration of 3068.28, 3006.42, 2823.10, 2707.06, 2500.54, 2216.87 and 2178.27 mg/m3 were 10 L/min, 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min and 70 L/min, respectively. The emission factor may be divided into mg/bhp-hr and mg/L-fuel; the emission factor of total carbonyls were 231.36¡B226.18¡B211.41¡B203.14¡B186.98¡B167.17 and 164.23 mg/bhp-hr, respectively; the emission factor of total carbonyls were 764.95¡B755.15¡B719.97¡B707.36¡B704.40¡B694.27 and 690.47 mg/L-fuel, respectively. Increases in H2/O2 can reduce total carbonyls emissions with an eliminating efficiency rate of 4.7, 6.6, 12.3, 15.9, 22.3, 31.1 and 32.3%, respectively. Energy conservation of appraisal increase H2/O2, diesel equivalent sun of fuel consumption of diesel engine and electricity consumption of H2/O2 generator, namely can distinguish that its energy consumption, whole consumes were 2.51, 2.58, 2.59, 2.57, 2.60, 2.43, 2.26 and 2.25, respectively. When compared with neat diesel, result showed in H2/O2 from 10 L/min to 40 L/min, diesel equivalent increased while H2/O2 showed increase; but in H2/O2 from 50 L/min to 70 L/min reflected in a gradual decrease in diesel equivalent, indicating that increases in H2/O2 can effectively achieve energy conservation. The result showed that energy conservation was 3.4%, 10.0% and 10.6% for 50 L/min, 60 L/min and 70 L/min, respectively. The result indicated H2/O2 was 60 L/min when energy conservation benefit was most remarkable, therefore this had the best energy conservation.

While quantitative investment management has been extensively investigated and many models built in order to provide investment suggestions through quantitative analysis, the combination of quantitative and qualitative analysis is relatively unexplored. The objective of this study is to construct a quantitative stock selection model based on the standard model built by Hsu et al. (2011) which could improve the stability of descriptor and factor structures and the combinability of quantitative and qualitative analysis. The research focuses on the structure of effective factors and descriptors when faced with different types of market trends. Furthermore, we test the performance of a Market Trend-Based Alpha Model (MTB alpha model) and compare with the standard alpha model. The strategy of portfolio construction is a TAIEX enhanced index fund. We find the enhanced index portfolio constructed by the MTB model produces an information ratio of 0.72, which is much higher than the standard model ratio of 0.41. This finding suggests that a MTB model could not only improve performance but also make the descriptor and factor structures more stable and much more easily for managers¡¦ adjusting.

The objective of this study is to build the platform, and the user can choose one model of the three models (1) base multi-factor alpha model (2) sector-specific alpha model (3) market trend-based multi-factor alpha model. The user can choose one target index of the four indexes (1) Electronic (2) Finance (3) Non-Finance Non-Electronics (4) TAIEX. The platform also combined the score of sector-specific model and market model, which we called hybrid model. The platform provides (1) elasticity of equity management (2) completeness of investment strategy (3) inclusiveness of alpha models and target indexes. The user can select a suit model and allocate the model and the target index, and quickly back-testing and evaluate performance. The contributions of this study are that help asset management companies quickly design investment strategies and back-testing, or product many different equity portfolio funds, and evaluate performance for stabled performance.

In this thesis, silicon oxide thin films fabricated on silicon substrates by reactive radio frequency (rf) magnetron sputtering and supercritical CO2 (SCCO2) treatment at room temperature were investigated. The electrical properties including I-V and C-V of the films prepared at different processing conditions were discussed. Using the Transmission Electron Microscope (TEM), the thickness of silicon oxide thin films were measured. The results suggested that the film quality can be significantly improved by the SCCO2 treatment after reactive sputtering. The leakage current of the films at an electrical field of 1 MV/cm is 1¡Ñ10-8A/cm2 with a hysteresis voltage of 0.01V. The silicon oxide thin films can be used as a barrier layer for Al/SiO2/Si silicon solar cells. The energy conversion efficiency of a single crystal silicon solae cell is 10.2% under AM1.5 (965W/m2) radiation. After rapid thermal annealing(RTA) at 500¢J, the measured short-circuit current, open- circuit voltage, fill factor are 53mA, 0.54V and 0.53, respectively.

This paper applies a Factor-Augmented VAR model proposed by Bernanke, Boivin and Eliasz (2005) to measure the impact of the monetary policy in Taiwan. Our empirical results show that, first, the more the factors added in the benchmark VAR, the more we can explain the price puzzle problem. Second, the effect of the tightening in the monetary policy (the increase in the interbank overnight lending rate) is inconsistent with the results expected by the credit channel.
