Introduction High power LEDs are currently in high demand for a variety of applications including flat panel displays, printers, optical interconnects in computers, and general lighting. However, due to the production of large amounts of heat in a small area, LEDs suffer severe cooling problems. Non-optimal heat dissipation will cause the junction temperature of device rising rapidly, and it will not only decrease the light efficiency, induce the peak wavelength shift and also significantly reduce the lifetime of LEDs. Therefore, the heat generation becomes the major barrier for the development high power LEDs. A proper thermal management to keep a good reliability and performance of LEDs is necessary. In this paper, we proposed three passive solutions to take away the waste heat of LEDs.

International Journal of Otolaryngology and Head & Neck Surgery 2018年第4期7卷 237-248页

作者： Byung Woo Lim Hae Dong Kim Jin Soon chang Ick Soo Choi Department of Otorhinolaryngology-Head and Neck Surgery Ilsan Paik Hospital Inje University College of Medicine Ilsanseo-gu Goyang-si Korea Department of Otorhinolaryngology-Head and Neck Surgery Seoul Paik Hospital Inje University College of Medicine Jung-gu Seoul Korea

Background: The clinical characteristics of burning mouth syndrome (BMS) are not fully understood. We investigated the profiles of BMS patients, characteristics associated with BMS, and the available treatment methods and their effects. Methods: Seventy-four BMS patients without oral mucosal lesions were enrolled. Their medical history, medications taken, and symptom scores were investigated via questionnaires. Laboratory investigations of parameters potentially associated with BMS were performed. Regarding treatment, 0.01% dexamethasone gargle, amitriptyline, and clonazepam were administered individually or in combination, depending on the degree of symptom improvement. Symptoms were scored from 0 - 10 points;these scores were used to evaluate treatment efficacy and patient satisfaction. Results: Mean age of the patients was 63.6 ± 14.2 years;mean symptom prevalence period was 15.5 ± 24.7 months. BMS was not significantly associated with a history of hypertension, diabetes, or any specific medications. Treatment reduced the symptoms of 85.1% subjects (63/74). Conclusions: Contrary to that in previous studies, we observed significant improvements in BMS patients following combination treatment with dexamethasone gargle, amitriptyline, and clonazepam.

沙眼的病原問題,經苏联及英美学者的研究,目前虽然沒有得到最后解决,但根据沙眼包涵体的研究,无疑地可以認为是病毒病。沙眼之有传染性而可以由人传染給人,人們久已观察到。拿破崙侵埃时沙眼發生流行而传染至欧洲大陸的歷史,我們已經談到过。1807年Vetch氏做了关于沙眼傳染性的很有兴趣的科学研究。Vetch氏將英軍部隊編作使用和不准使用公共手巾的兩隊,結果沙眼在兩隊中的散布情况有天壤不同,不用公共手巾的部隊中沙眼例子很少,而使用公共手巾的部隊中則很多。試驗結果虽然極明顯的指出傳染沙眼的媒介物,可惜在150余年后的今天,公共手巾还在繼續使用着。1823年Wernicke氏以人体試驗方法,首先証明可以直接接种由人傳染于人。自1823年至1937年間,重复人体試驗者,据Julianelle氏,有35人,共作試驗108次,結果陽性者有68%。

在各种化学蒸气沉积生长排列整齐的纳米材料的合成方法中,阳极三氧化二铝(AAO)模板被广泛采用主要由于容易通过电压和阳极氧化时间来控制其孔径.这里,我们表征存在/不存在催化剂时生长在AAO模板上的碳纳米管和氧化物材料的生长机理.我们还研究了在合成密集整齐排列的纳米结构生长过程中氢气的还原效应.实验结果显示AAO模板本身促进Ga2O3VS生长机理,氧化物催化剂氢化还原提高了碳纳米管的生长速率和结晶度.氢化还原中使用AAO模板可以很好地控制排列整齐的纳米材料的直径和密度.
