臺北市立國民中學兼任行政職務之教師其角色衝突與幸福感之相關研究

[[abstract]]Abstract The object of this study is to study the role conflict and subjective well-being for teachers in Taipei municipal junior high school, who hold a concurrent post of administration job. There are four major purposes for this study, which are: 1、to pay close attention to the situation of role conflict for a junior high school teachers who hold a concurrent post of administration job in such a fast-changing environment. 2、 to pay close attention to the feeling of being blissful for junior high school teachers who hold a concurrent post of administration job, as the topic of「subjective well-being」is gradually getting more people’s attention. 3、to understand the interrelated factors which influence the subjective well-being for teachs who hold a concurrent post of administration job. 4、to probe into the relationship between role conflict and the subjective well-being for junior high school teachers who hold a concurrent post of administration job. This study is conducted with the method of census, and takes samples out of the 774 teachers who hold concurrent post of administration job in 59 municipal junior high schools, among 12 municipal administration districts of Taipei city. This study uses the self-made 「Assessment Table of Role Conflict and Subjective well-being for Junior High School Teachers Who Hold a Concurrent Post of Administration Job」as tool, and statistically analyzes the obtained quantified material with descriptive statistics, one-way ANOVA, t-test and Pearson Product-Moment Correlation. After the study, major findings are as the following: A、 The situation of role conflict for teachers in Taipei municipal junior high school, who hold a concurrent post of administration job can be classified as below the medium level, but the inner and outer value conflict is above medium level. And the variable of different background for a junior high school teachers who hold a concurrent post of administration job in the diverseness of role conflict degree is stated as below: (1) for junior high school teachers who are age below 30, graduated from teachers’ school, concurrently holding administration post less than 5 years, teaching in a school of「13-24」classes, the role conflict degree is more higher, and vividly above the average level. (2) for junior high school teachers who are in different gender, marital status, working offices, and position, the diverseness of role conflict is not so vivid. B、 the subjective well-being for teachers in Taipei municipal junior high school, who hold a concurrent post of administration job can be classified as above medium level, among which the subjective well-being in family relationship is regarded as the highest one, as for the one in job achievement is less. And the variable of different background for junior high school teachers who hold a concurrent post of administration job in the diverseness of subjective well-being is stated as below: (1) for junior high school teachers who are age above 51, married, with master degree, and teaching in a school of「25-48」classes, the subjective well-being degree is more higher, and vividly above the average level. (2) for junior high school teachers who are in different gender, working offices, current position, and administrative experience in years, the diverseness of subjective well-being does not reach the level. C、 there is negative relationship between role conflict and the subjective well-being for junior high school teachers who hold a concurrent post of administration job, and neither of them reaches the standard level. In the end, a conclusion and specific suggestion is made, in order to provide reference material to administration departments in junior high schools, teachers who hold a concurrent post of administration job, and relevant education authorities for further study.

医院感染多重耐药菌分布及耐药性分析

目的了解医院感染多重耐药菌分布及耐药性分析,为临床诊疗提供依据。方法 25 618例临床感染标本分离株培养鉴定后,监测常见分离菌的多重耐药菌株(MdrO)。结果 1 087株分离菌以革兰阴性菌925株为主,革兰阳性菌162株。革兰阴性菌中分离率前5位分别是肺炎克雷伯菌、大肠埃希菌、铜绿假单胞菌、鲍曼不动杆菌、阴沟肠杆菌。革兰阳性菌中分离率前5位分别是金黄色葡萄球菌、凝固酶阴性葡萄球菌、肺炎链球菌、屎肠球菌、粪肠球菌。大肠埃希菌、肺炎克雷伯菌产超广谱β-内酰胺酶(ESblS)株的检出率分别为75.53%、37.14%;金黄色葡萄球菌中耐甲氧西林的金黄色葡萄球菌(MrSA)的检出率为78.20%,凝固酶阴性葡萄球菌中耐甲氧西林的凝固酶阴性葡萄球菌(MrCnS)的检出率为84.60%。13株屎肠球菌中发现3株万古霉素耐药株(VrE)。结论医院感染多重耐药菌分布主要以革兰氏阴性杆菌为主,其次是革兰氏阳性球菌。MdrO的增多是医院面临的重要问题,在临床上应改进治疗手段,合理使用抗菌药物,减少MdrO的产生和播散

Study on crop-pan coefficient of greenhouse tomato under non-pressure irrigation

以-25 kPa作为土壤水势临界值,将作物—皿系数(Kcp)设为0.2,0.4,0.6,0.8,1.0,1.2六个处理,研究了不同灌溉水量时的番茄产量、品质和灌溉水利用效率。通过经济效益评价,研究了杨凌地区无压灌溉温室番茄获得最高经济效益时的作物—皿系数。通过张力计读数变化规律,研究了利用张力计测量无压灌溉湿润体内土壤水势的特点。研究结果表明,Kcp为0.2~0.8时,灌溉水量的增加对番茄产量影响不大;Kcp为1.0~1.2时,灌溉水量的增加能显著提高番茄产量和果实大小;Kcp为0.2时的灌溉水量能极显著提高番茄的灌溉水利用效率。在综合考虑了杨凌地区水价、番茄使用目的和市场价格波动规律后,Kcp取值1.2能获得最高的经济效益。作物—皿系数法计算灌溉水量时的滞后性特点和张力计埋设位置,是判断利用张力计监测土壤水势临界值方法有效性的两个重要因素

The Variable Rule and Empirical Solution on Characteristic Value of Wetted Zone under Non-pressure Irrigation

无压灌溉土壤湿润体形状为球冠,径向和垂向最大湿润距离相等且与时间存在显著的幂函数关系,随着时间的延长,径向和垂向最大湿润距离趋于一定值。湿润体大小与供水压力之间呈抛物线关系,在零压力附近湿润体体积最大。湿润体半径与累计入渗量呈幂函数关系,拟合方程中的系数和指数为一定值,与入渗时间和供水压力无关,在试验条件下,分别为18.467和0.5037。综合以上结果,提出了预测无压灌溉土壤湿润体特征值的经验解模型
