中部某醫學大學護理系大一新生憂鬱症狀盛行率及其相關因素

In this study, the zirconia coating technique was applied to analyze surface properties of titanium castings. The mixed slurry of zirconia powder and commercial phosphate liquid Begosol(superscript ?) (100% and 50%) was coated on the wax pattern respectively, and the commercial phosphate-bonded investment material was invested using a double-investing method. The commercial MgO investment material with traditional investing method was as control. Then, the commercial pure titanium alloy was used for casting. The surface roughness and Vicker's hardness test were performed on the titanium castings, and the surface microstructure of titanium castings were observed and analyzed by optical microscope. The surface roughness (Ra) of titanium castings obtained from experimental group and control group were 0.16~2.02 μm and 0.22~1.37 μm respectively. There is no significant difference between experimental group and control group. The thickness of titanium surface reactive layer was about 150 μm. The zirconia coating technique used in this study can be applied to cast titanium alloy.
本研究目的主在了解某中部醫學大學護理系大一新生的憂鬱症狀現況，並進而探討其基本資料如自覺壓力、人格堅韌度與人格特質對憂鬱症狀的影響，並找出影響憂鬱症狀最主要的因素。採橫斷式調查，以自填問卷方式共取樣112位學生。資料收集包括基本資料、簡短版艾森克人格量表(EPQ-RS)、台灣人憂鬱量表(TDQ)及人格堅韌度量表(HRHS)，以描述性、Pearson's相關係數、複迥歸分析等方法進行資料分析。結果顯示(1)約有21.42%學生有憂鬱症狀，中度憂鬱症狀佔18人(16.07%)，嚴重憂鬱症狀佔6人(5.35%)。(2)人格堅韌度屬於中等程度，表示大多相信自己的行為能決定健康狀況，盡可能讓自己維持健康。(3)神經質人格特質、人格堅韌度（控制）、自覺壓力、神經病質人格特質為大一新生憂鬱症狀之預測變項，共解釋53.2%之變異量，其中以神經質人格特質為最主要之預測變項。本研究結果可提供大學教育輔導方針及未來後續研究之參考。
