應用GIS於社區淹水潛勢區分析及潛勢危險區劃分研究
Study on application of GIS to potential inundating area analysis and potential risk area delimitation for community
摘要
臺灣四面環海、地處亞熱帶，夏、秋兩季常有颱風及西南氣流，且河川上游坡陡流短、水勢湍急、集流時間短暫，中下游多為地勢平坦之丘陵、平原，故屢造成嚴重水患，導致社經與生命財產的損失。觀其主因概是由於土地超限利用導致自然平衡破壞，且對流域相關水文、地文特性及水情認知不足，無法掌握洪澇情勢，因而無法及時預防及控制水情。因此要減輕洪澇災害損失，需瞭解並掌控水情與災情，明瞭不同程度暴雨下，可能造成的洪澇淹水規模，評估可能造成的災害危險度與其損失，以強化洪災緊急應變能力。故本文以示範社區之各頻率年設計暴雨的淹水深度資訊，藉統計期望值觀念，計算年期望淹水深度，做為淹水潛勢指標，據以標定淹水潛勢區，並進行危險度分級，以得潛勢危險區分佈態勢，使居民及相關機構在暴雨時，得以據其預作警戒，減免洪澇災害損失。

Background: Nursing shortage is due to high turnover rate in Taiwan. Purpose: The main purposes of this study were to explore 1. turnover intention 2. the relationship between job stress, job satisfaction, organizational commitment and turnover intention among nursing staff who work in a medical center in central Taiwan. Methods: Study design is cross-sectional. One hundred and sixty-four validated staff nurse were recruited. Structured questionnaires included job stress, job satisfaction, organizational commitment and turnover intention were used to collect data from subjects via self-administration. Data analysis used multiple regression. Results: The average mean score of turnover intention was 2.83. There were significantly positive correlation between job stress (p ＜ .001) and turnover intention, and negative relationship between job satisfaction (p ＜ .001), organizational commitment (p ＜ .001) and turnover intention. Multiple regression showed that job stress, job satisfaction and organizational commitment explained 43.5% of the total variance in turnover intention. The predictors of turnover intention were job satisfaction, continuance and normative commitment, and that meant the less job satisfaction, continuance and normative commitment the more turnover intention. Conclusion/Implications for practice: Increasing job satisfaction, continuance and normative commitment may decrease turnover intention among nursing staff.
