ABSTRACT This research is mainly based on the concept of ¡§strategic triangle¡¨described in Mark H. Moore ¡¨Creating Public Value¡GStrategic Management in Government¡¨, and the environment system is surveyed with the viewpoint of ¡§an integrated public affair management framework¡]PAM¡^¡¨ which is developed by Wang, Ming-Shen. In Taiwan, the National Health Insurance Act has been the most important social welfare policy since its launching in 1995. The main purpose of the policy is to reduce the economic barriers of medical care. However, medical service in remote areas, especially in offshore islands, still has been a difficult issue for government. Officers are designated to carry out the politics of the democratically elected head of a local government, and have to create public value by succeeding at the task. Although it is difficult to build rural health care network, the executive officers as managers must achieve it with efforts. Moore has developed a simple and powerful diagram ¡§strategic triangle ¡¨ which is composed of V.C.S. to focus the attention of government managers on three complex issues they had to have considered before¡]or,while¡I¡^committing themselves and their organizations to a particular course of action. This retrospective case study takes the executive officer in local government as the public manager who takes the responsibility of running effectively the Lieyu Branch of Kinmen County Hospital in Lieyu Township in response to its residents demand. In illustration of the medical care project in stages , managers will realize the process and outcome that show¡G¡§an integrated public affair management framework¡¨ enables the public manager to evaluate the overall environment in clear presentation¡Fand ¡§strategic triangle ¡¨ helps the public manager to identify promptly the shortcomings and practical suggestions of the project.

This research is mainly, composed of Mark H. Moore ¡§Creating Public Value¡GV.C.S. strategy management in government¡¨, and promoted by Wang, Ming-Shen with the viewpoint of ¡§An integrated public affair management ¡]PAM¡^ framework¡¨.

ABSTRACT Benthic foraminifers that host algal symbionts are similar to corals in that they rely on their algal endosymbionts for their energy needs, calcify prolifically, and are sensitive to changes in environmental conditions. They are abundant in the benthos of coastal coral-reef areas and are found throughout the tropical and subtropical regions. Pulse Amplitude Modulated (PAM) chlorophyll fluorometry and chlorophyll a extraction techniques were used to quantify and compare the photosynthetic responses of the benthic foraminiferal, Archaias angulatus and their isolated endosymbionts, Chlamydomonas hedleyi, to short-term changes in temperature. Maximum quantum efficiency (Fv/Fm) and rapid light curves (RLCs), from which relative electron transport rates (rETR) of photosystem II (PSII) were derived, were investigated over a thermal range from 4.4° to 33.9 °C in three experiments that were 7 to 31 days in duration. Typical mean yields (Fv/Fm for healthy holobionts (symbionts in hospite) were 0.6 - 0.7, and for isolated symbionts 0.5 - 0.6. Chronic photoinhibition, indicated by significant decreases in Fv/Fm, occurred at temperatures above 31.0°C; there was minimal reduction in efficiency in cooler treatments. The trends between holobiont and symbionts were very similar in all of the photophysiological parameters measured [yield, photoefficiency (<α>), ETRmax and minimum saturating irradiance (Ek)] and supported the temperature range findings in terms of the tolerance of the specimens in the low temperatures up to 31.0 °C. For all photochemical measurements assessed, the holobiont values tended to be somewhat higher than those for the symbionts, with the exception of Ek, possibly indicating a tight coupling in the host-symbiont response during photosynthesis. Chlorophyll a (<μ>g/foram) was negatively correlated with temperature (r = -0.37, p < 0.001) in Experiments 1 and 2. However, in all 3 experiments, chlorophyll a was variable, suggesting a high degree of individual variability in A. angulatus and the ability to acclimate. Some differences observed among treatments may be related to differences in seasons when the specimens were collected and in length of time in culture prior to experiments. Holobiont median rETR light curve trends and photophysiological derived parameters recorded median Ek ranges of ~100-150 <μ>mol photons m-2 s-1, observed ETRmax light intensities of ~200 <μ>mol photons m-2 s-1 and photoinhibition, induced by increasing irradiance intensities, which occurred > 500 <μ>mol photons m-2 s-1. These light curve trends and derived parameters generally supported previous photosynthesis O2 and CO2 gas production studies of A. angulatus. The differences in responses associated with acclimation should be considered in design of future experimental studies. This was the first known physiological study of the viable temperature range and photobiology of A. angulatus using chlorophyll fluorometry methods. Though commonly found in Caribbean and Atlantic waters ranging from 14.0 - 31.0 °C, these results indicate a wider thermal-tolerance range for A. angulatus than was previously known.

The critical micelle concentration was determinated by the measurements of electrical conductivity and absorption, using electrical conductivity and UV-vis absorption spectrometry methods. The variation of acidic-basic properties of dyes in aqueous solutions was evaluated by estimation the values of the negative logarithm of dissociation constant of the dye and thermodynamic parameters of dyes-surfactants solution. The critical micelle concentration of sodium dodecyl sulfate, dodecyltrimethylammonium chloride and 1-dodecyl-3-methylimidazolium chloride was determinated in aqueous and phosphate buffered solutions of the Janus Green B dye. The value of critical micelle concentration of anionic, cationic surfactants and ionic compound depends on the pH value of the solutions, it can be observed that increasing the ionic strength of solution the value of critical micelle concentration decreases. The values of the negative logarithm of dissociation constant of Acid Orange 7 and Acid Blue 80 dyes varied depending on the temperature of aqueous solution, the pH value and the nature of used surfactants. It was estimated, that the lowest value of pKa of Acid Orange 7 dye was then the amphoteric surfactant - cocamidopropyl betaine was used in the dye solution and for Acid Blue 80 dye – nonionic...

Bitumen recovery by the water-based extraction process produces waste streams known as tailings. When discharged into the tailing ponds, the coarse solids in the tailings stream settle out quickly, while the fine solids accumulate over years of settling to a solids content of 30-35% by weight. The formed fluid fine solids sludge, known as mature fine tailings (MFT), traps 1-3% by weight hydrocarbons within its stable slurry structure. The remediation of these mature fine tailings is one of the major challenges facing the oil sands industry. This study was intended to investigate the recovery of residual hydrocarbons in the MFT by froth flotation process. Using a laboratory Denver flotation cell operated in a batch mode, the effect of MFT dilution ratio by process water or tap water, the flotation hydrodynamics and aeration rate on hydrocarbon recovery kinetics was studied. It was found that at 1:2 dilution by weight of the MFT with process water, increasing aeration rate has a more favourable effect on recovering more than 85% of the hydrocarbons from the MFT. The hydrocarbon-rich froth produced was treated by naphtha and was found to produce a hydrocarbon product similar to diluted bitumen obtained in bitumen extraction process, suitable for upgrading. Similar approach was applied to the hydrocarbon-rich tailings from the Tailings Solvent Recovery Unit of paraffinic froth treatment. Satisfactory recovery of hydrocarbons from the MFT was obtained using a flotation column operated in a continuous mode, confirmed the results obtained from the batch tests. The tailings produced from the continuous flotation experiments were treated with polymer flocculants such as Magnafloc-1011 and Al-PAM to study the effect of hydrocarbon recovery on the remediation of the MFT. The results from initial tests showed that both flocculants were not as effective on flocculating MFT solids following the recovery of hydrocarbons by froth flotation. / in Chemical Engineering
