Methods: A retrospective study was conducted using an insurance database from Bureau of Nation Health Insurance - Central regional branch with registered children born in 2001 who received teeth fluoridation and anti-decay program. The difference of utilization of dental care preventive service analysis was based on each individual child's character and required dental treatment. For cost-benefit analysis, children were selected who were eligible receiving or non- receiving this benefit from July 1, 2004 till 2007. Two groups were compared by frequency matching analysis, based on sex, medical provide territories, insured fee. Additional Incremental benefit/cost method of cost-benefit analysis is also conducted to evaluate the service providing cost increasing and dental treatment cost decreasing effectiveness.

研究方法主要系透过健保局中区分局93年至96年儿童牙科医疗费用统计资料，比较90年次出生之儿童接受涂氟预防保健服务之人口学特质及其涂氟前后牙科医疗利用差异；并依该等对象接受涂氟预防保健服务与否区分两组，就其性别、就医地区别与全民健保投保金额组别等予以配对，进一步应用成本效益分析（cost-benefit analysis，CBA）之增量益本比（Incremental benefit/cost method，IBC），探讨儿童牙齿涂氟预防保健服务成本的增加，使牙科医疗费用减少所带来效益的增加为何。

BVD-MDV was inspected with hogcholera antibody marked by fluorescein for the first time, and prevention BVD-MD by inoculating hog cholera attenuated vaccine.

首次应用猪瘟荧光抗体检测BVD-MDV，采用相应的弱毒苗或灭活苗来预防和控制本病，猪瘟活疫苗免疫注射的方法预防BVD-MD，同样获得了较好的免疫预防效果。

RESULTS: The average score were 82.72 points and 73.9 points respectively for the year 2002 students majored in clinical medicine and year 2003 students specialized in forensic medicine, who had received both classroom teaching and clinic noviciate.

结果：接受见习教学的医学系和法医系学生的平均成绩分别为82.72和73.9分，未接受见习教学的预防医学系学生的平均成绩为75.6分，经统计学分析，医学系学生的成绩好于法医和预防医学系，而法医和预防医学系的学生成绩没有统计学差异。

And the lesion number of severest diseased stem is over 100, the percentage of disease in Brown Spot is around 60%. From the result of fungicide test, we know the Difolatan, Benlate and Orthocide are the more effective for controlling Stem Blight, but the percentage of prevention don't reach the perfect effect. The effect of other fungicides is not good. So we must continue to work to search for safe, and ideal fungicides as the index of prevention.

由药剂试验结果，以Difolatan（预防率：100p.p.m为80.95%，200p.p.m为83.33%），Benlate（预防率：100p.p.m为85.71%，200p.p.m为92.85%），Orthocide（预防率：100p.p.m为71.42%，200p.p.m为73.80%），三种药剂对茎枯病之防治效果最佳，但预防率未达百分之百，其他药剂之防治效果不佳，故仍需进一步寻求安全、有效之防治药剂，以供今后笋农防治茎枯病之依据。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
