人的腳部會因為長時間在戶外走動,經過風吹、日曬、雨淋後造成腳部悶熱、不適,進而導致腳部受到細菌感染,產生香港腳等腳部疾病。若鞋內織物具有良好的抑菌效果,可使鞋內的細菌不再繼續滋生,達到腳部健康衛生的效果。本實驗以聚酯針軋不織布為基材,採用奈米銀抑菌劑,目的是為了尋找合適的加工條件,使不織布具有良好的抑菌效果亦節省成本,以提供業界作為製造參考依據。經由實驗觀察,未添加壓克力樹脂之抑菌劑在室溫下會產生褐色斑,有變色現象。本研究以金黃色葡萄球菌及肺炎桿菌測試其抑菌效果得到,60、90、120ppm之奈米銀抑菌劑添加及未添加壓克力樹脂之布樣上菌無大量孳生,皆有抑菌效果,但效果不明顯。

影響網路平價時尚品牌評價因素之研究 Study of Evaluation Factors on Internet Brands of Cheap and Fashion黃文靖、余?雯、羅淑芳、莊龍隆
摘要預覽 Preview abstract收合摘要 Hide abstract
時尚產品並非適合網路行銷的標準品,目標顧客是網路購物金額較少的年輕女性,但仍有不少成功的網路平價時尚品牌公司,因此這些消費者特性如理解層級、價格敏感度及時尚喜好度等就值得深入討論,本研究先收集消費者理解層級內容,依此設計問卷,再利用網路問卷進行量化資料收集,分析年輕女性理解層級、時尚喜愛程度及價格敏感度對網路時尚品牌評價的影響。 網路購買平價時尚品牌消費者(1008個受訪者)以18-26歲、專科/大學、每月平均上網瀏覽次數多在4次以上,每月平均服飾花費以1,001-3,000元,花費在特定袋包上有201-500元最多。本研究透過方法目的鏈去了解購買網路時尚品牌包包消費者最大價值為心靈滿足,平價是購買動機,包包流行時尚的整體造型及良好的物品收納功能是利益。消費者對品牌理解程度愈高,品牌評價就愈高,價格敏感度(負相關)及時尚喜好度(正相關)均對理解層級具有調節效果。
Fashion products which are not standardized products are not suitable to be sold through internet. The purchasing expenses of young ladies who are the main consumers for internet fashion products are lower than others. However, there are still many successful internet brands of cheap and fashion. Therefore, consumers’ traits such as price sensitivity, preference of liking and understanding chains are worth discussing. We collected the contexts of consumers’ understanding chains to design questionnaires. The internet questionnaires were used to collect quantitative data to analyze factors …

本研究是利用液中硬化法透過自組裝設備製備出單核型海藻酸鈉微膠囊,以海藻酸鈉為殼材,樟腦油為芯材,藉由改變殼材濃度及交聯劑濃度探討其釋放性差異並計算包覆率,觀察成形性及其粒徑。由實驗結果顯示,殼材濃度較低之海藻酸鈉微膠囊釋放時間較長釋放量較高,因殼材濃度較高時其分子結構較緊密較不易穿透而造成釋放效果較差,同時在不同殼材濃度與不同交聯劑下所製備出之單核海藻酸鈉微膠囊其包覆率皆在95%以上,當殼材海藻酸鈉濃度由0.75~1.75wt%逐漸增加時,其粒徑亦隨之增大。
This study was conducted using through home-made equipment by an orifice method to make the single core alginate microcapsule. The sodium alginate was used as wall material and the core material is camphor oil. In order to measure the different degree of release, calculating encapsulated ratio and the average size of the microcapsule, a variety of concentrations of shell material and cross-linking agent were used. The result indicated that the longer release amount of releasing time is relatively high when the concentrations of shell material lower. The result-ing effect is a result of poor r…
