    靈芝子實體中之有機鍺成份研究
    (國立臺灣師範大學研究發展處, 1989-06-??) 姜宏哲
    以含有0.6、63、126、252ppm鍺(添加二氧化鍺配製)等不同濃度之太空包栽培赤芝,結果所生長的赤芝中之鍺含量分別為2.1, 45.2, 82.3, 116.8ppm。由含有82.3ppm鍺之赤芝,經95%乙醇回流萃取後,以矽藻土管柱層析法分離2次,獲得含有21,739.8ppm鍺之部分。

    台灣地區電氣機械製造業區位變遷的計量研究
    (國立臺灣師範大學研究發展處, 1983-06-??) 李薰楓
    The purpose of this paper is to analyse the manufacturing characteristics of machinary industries in Taiwan. The paper is based on the data of the Census of Manufacture and Commerce for 1954, 1961, 1966, 1971 and 1976 as well as on some measures, such as the location quctient, Conkling's diversification index, shift-mix analysis, multiple regression and factor analysis. These measures will be used to evaluated locational changes of machinary industries in Taiwan. Based on quantitative methods, statistical tables and map figures, some conclu-sions have been reached in the apper.

    噪音對人體聽覺影響之實驗研究
    (國立臺灣師範大學研究發展處, 1983-06-??) 王老得
    An experimental study on the noise-induced hearing loss or noise-induced temporary threshold shift (NITTS) of the normal hearing college students (30 male and 30 female) was performed with three kinds of narrow band noise, including 250Hz, 1 KHz and 4KHz octave bands, and six different sound pressure levels of broad band noise, which were used white noise at sound pressure levels of 65, 70, 75, 80, 85 and 90 dB as stimulating tones.The mean age of this study subjects was 21.28 years in male group and 21.8 years in female group. First of all, all subject were measured with their hearing levels by using Rion AA39 audiometer, and then the persons with less 15 dB in average hearing level of speech range (500Hz, 1KHz, and 2KHz) were selected as the normal hearing subjects. The actual mean values were 9.55 dB in male group and 9.83 dB in female group.Two minutes after exposure to each stimulating noise ceased, the subject was retested with the hearing levels on 4KHz and 6KHz, and then compared with that of preexposure to the stimulating noise. If the difference of value between pre-and post-exposure hearing level on 4KHz or 6KHz shows 5 dB or greater, it is defined as a positive response of NITTS.The inciaence of positive TTS2 shows 65% among 60 subjects after 50 seconds of exposure to the broad band noise; and 3.3%, 16.7%, 30% after 50 seconds of exposure at 70 dB SPL to the 250Hz, 1KHz, 4KHz octave-band noises respectively.According to Reed-Muench bioassay method, LD50 value shows 80.99 dB SPL for the white noise exposure, In other words, 50% of subjects in this study group reveals positive TTS2 after exposure for 50 seconds to white noise at 80.99 dB sound pressure level.So the 81 dB SPL of the white noise may be referred to as the risk-criterion limit of "Noise Control Administration in Taiwan" for the broad band noise. If the environmental noise contains the 4KHz or higher pure-tone components and/or high octave bands, the risk-criterion limit must be decreased reaso

    磺胺劑亞硝基脲衍生物之分解度研究
    (國立臺灣師範大學研究發展處, 1991-06-??) 姜宏哲
    比較潛能抗癌劑N-(2-氯乙基)-N-(亞硝基)?基磺胺甲噁性[1],N-(2-氯乙基)-N-(亞硝基)?基磺胺甲氧噠[2],N-(2氯乙基)-N-(亞硝基)?基磺胺二甲嘧啶[3]及N-(2氯乙基)-N-(亞硝基)?基磺胺異噁唑[4]等之分解速率,固態狀況時在室溫及50℃,液態狀況在pH7.4,37℃之緩衝溶液中等三種不同狀況下測定,求時間與分解度關係。發現化合物(2)在pH7.4的緩衝溶液中之半衰期為60分與現臨床上使用之涇化劑類抗癌藥BCNU相同,因此可能有抗癌作用。
