Wetlands provide vital habitats for fish and wildlife while offering numerous other benefits. As in some other countries, however, Taiwan has witnessed the loss of a significant portion of its coastal wetlands due to large-scale reclamation projects along the coast. Most of the wetlands that still remain are seriously being threatened by both human activities and natural changes, such as drainage for agricultural production, filling for industrial development, discharge of wastes and drought. The administrative performance of the existing authorities and legislation in Taiwan has mostly been ineffective in protecting these precious, sensitive areas. This paper introduces the distribution of wetlands in Taiwan and highlights their invaluable functions and potential economic value. It also discussed the recent activities, both initiated by the government and the NGOs, to protect wetlands in Taiwan. Based on the above discussion, the paper identifies the wide-range of current problems related to their management and proposes the vision should have to save wetlands for the future. It argues that establishing clear policies and effective institutional mechanisms on wetland protection and conservation, classifying the wetlands for better management, and fully promoting public awareness and consciousness of the importance of the wetlands will not only be beneficial but will also address the urgent need to safeguard the wetlands in Taiwan. Additionally, the paper recognizes that international cooperation and collaboration on wetland restoration is essential and most challenging.

We propose new driving schemes, asymmetry and long gap mode, of PDP having auxiliary electrode between scan and common electrode. For the asymmetric modes, the auxiliary electrode located nearly center of the primary electrodes is connected to the scan of common electrode during all periods of reset, address and sustain. For the long gap mode, it is electrically disconnected or maintained at dc voltage of Vs/2 during sustain period except the first several sustain pulses. The proposed structure and driving method can provide higher luminous efficacy by minimizing consumption energy. The effectiveness of the new driving schemes has been investigated for various Xe partial pressure conditions.

AC PDP with MgO protective layer coated with the optimum evaporation rate of $5{\AA}/s$ can generate more enhanced efficiency through the vacuum in-line sealing process. However, the optimized process conditions still require the optimum driving scheme on the ramp-up and ramp-down slope of the reset waveform for enhancing the efficiency. In this paper, for the in-situ vacuum sealed PDP with the optimum evaporation rate of MgO protective layer, the address delay time was investigated with various slopes of ramp waveform during a reset ramp-up and ramp-down period. In this study, the minimum statistical delay time was obtained at the ramp-up rate of $6.0 V/{\mu}s$ and the ramp-down rate of $0.7 V/{\mu}s$ of the reset waveform.

From 1990 to 1997 Home Care Education Programs have been offered at 11 Home Care Education Institutes. But there have been no revisions in the program. Especially in the clinical practicum, the Ministry of Health and Welfare proposed 248 hours as 'Family Nursing and Practice'. But each of institutes has developed their own program, and the clinical practicum is very different. Institutions for home care practice have been very limited and even now only 40 hospitals started home care in the second demonstration project. A few community-based institutions have also been offering home care services. This study was conducted to analyze home care clinical practicum offered at Y university, and plan for a revised home care clinical practicum. Y university clinical practicum was revised to include 'visits to community institutions', 'laboratory practice', 'hospital practice', 'discharge planning and home care practice', and 'home care specialty practice'. The results of the evaluation and plan for a revision are as follows: 'Visits to community institutions' is a practice that helps the students understand community resources which are available to home care nurses, and as an orientation to institutions for practice. 'Laboratory practice' is to used to improve nursing skills that are applicable to home care. Problems that the students identified in the laboratory practice were 'lack of opportunity for individual practice', and 'inadequate theoretical preparation for practice'. To address these problems the basic nursing skills laboratory was open and could be used freely by the home care students, and practice could be done after the theoretical lectures. 'Hospital practice' is a practicum in which the students apply nursing skills to patients and to obtain assessment skills for discharge planning. Using a preceptorship, five days for hospital practice should be offered. 'Discharge planning and home care practice' was done at Wonju Christian Hospital. This institute is too far away that this practice should be provided at different institutions as soon as it is possible to contract with home care institutions. Patients groups in different home care institutions are very different, so the 'Home care specialty practice' should be done after analyzing patient groups and choosing specialty areas. These areas are' care of patients with respiratory dysfunction', 'care of patients with neurologic dysfunction', 'care of cancer patients', 'care of patients on dialysis', and 'wound care'. This practice should be offered with a preceptorship, so preceptors, clinical directors, and students should meet for home visit orientation.

This study is analyze future climate and land cover change affects behaviors for amount of streamflow and sediment discharge within basin. We used the climate forecast data in RCP 4.5 and 8.5 (2011-2100) which is opposite view for each other among RCP scenarios that are discussed for 5th report for IPCC. Land cover map built based on a social economic storyline in RCP 4.5/8.5 using Logistic Regression model. In this study we set three scenarios: one scenario for climate change only, one for land cover change only, one for Last both climate change and land cover change. It simulated amount of streamflow and sediment discharge and the result showed a very definite change in the seasonal variation both of them. For climate change, spring and winter increased the amount of streamflow while summer and fall decreased them. Sediment showed the same pattern of change steamflow. Land cover change increases the amount of streamflow while it decreases the amount of sediment discharge, which is believed to be caused by increase of impervious Surface due to urbanization. Although land cover change less affects the amount of streamflow than climate change, it may maximize problems related to the amount of streamflow caused by climate change. Therefore, it's required to address potential influence from climate change for effective water resource management and prepare suitable measurement for water resource.

As the demand for lithium-ion batteries with high capacity and high energy density has rapidly increased, silicon anodes (theoretical capacity = 3,570 mA h g^-1) have garnered attention as potential replacements for conventional graphite anodes (theoretical capacity = 372 mA h g^-1). However, silicon anodes suffer from severe volume expansion (~360%) during lithiation, low ionic conductivity (10^-14 ~ 10^-13 cm² S^-1), and low electrical conductivity (10^-2 S cm^-1), resulting in poor cycling and rate performance. To address these issues, this study synthesized core@shell-structured silicon@carbon nanoparticles (Si@C NPs) via a one-pot spray pyrolysis process using Pluronic-F127. Pluronic-F127 in the spray solution contributes to the synthesis of nanoparticles by preventing the formation of silicon nanoparticle/dextrin agglomerates and by undergoing pyrolysis simultaneously. Additionally, dextrin derived amorphous carbon was coated on the surface of the silicon nanoparticles to act as an electron transport pathway within the anodes and enhance the electrical contact between the silicon nanoparticles. The Si@C NPs exhibited a discharge capacity of 1,912 mA h g^-1 after 50 cycles at 1.0 A g^-1 and high rate capabilities (discharge capacity of 1,493 mA h g^-1 at 3.0 Ag^-1). The silicon@carbon composite nanoparticle synthesis strategy based on the spray pyrolysis process presented in this study is expected to offer a new direction for improving the performance of silicon anode materials.

Purpose: The purpose of this study was to identify the frequency and status of mentally ill patients who registered in a community health center (CHC) but they could not be accessed. Methods: A total of 233 mentally ill individuals who were registered to a CHC in B Metropolitan City participated in this survey. Data were collected from December 1 to 31, 2010 and analyzed. Results: There were 140 (60.1%) community dwelling mentally ill patients who had been registered to that CHC but were not accessible. The major reasons of this inaccessibility were patients' rejection to be accessed (27.1%) and the wrong or missing address in hospital's discharge note (22.9%). The nursing problems of the subjects were rejection of medication (93.4%); poor personal hygiene (85.8%); violence including harassment of family member(s), assault, property destruction, threat with weapon (38.7%); and so on. Among 159 cases of referrals and requests for help immediate action with patient's compliance were only 8.8%. Conclusion: The findings show that mentally ill patients who had registered to the CHC but were not able to be accessed failed to be managed properly. This would become risk factors of social problems which threat to the community as well as individuals. Thus, we need to prepare programs for this population to make them take medicine at a minimum.

Most of the movies currently being created are used by CG. As for movie of today, the location of visual effect from film business rose highly with CG introductions to do not ask a style. The CG gets attention recently, and expand a market at rapid pace, the biggest reason are development of software and computer hardware. Advancement of computer technology and technique discharge numerous VFX artists therefore visual effect are possible to deliver with low-budget feature and commercial films more common. As for CG fields Hollywood in United States has most advancement of the computer techniques that create a lot of visual effect artists. However CG techniques of Korea also developed absurdly, because movie market of Korea is getting bigger. Korean CG technology get catching up at the CG techniques of Hollywood every year, however goal of this research in order to study is current address and future possibility of development of Korean CG. The CG example which from the movie was already screened that in the depth. Through movie of existing and knows a different partial authorization, tries to observe the possibility of development of future Korean CG fields.
