Sluice Gate에 依한 Hydraulic Jump 現象에 關한 實驗的 硏究
李吉永 大田工業專門學校 1976 論文集 Vol.17 No.-
This paper describes the study and test for Hydraulic Jump below sluice gate and also contribute to the athorization of Hydraulic Flow channel for the practical purpose. As a result of experiment study on Hydraulic Jump: 1) The relationship between experiment numbers and theoretical is thus Froude number (F_N)=3.40~5.24. so that F_N is given by Steady Jump and Oscillating Jump. Also the relationship between Froude number and h_2/h_1(Depth ratio) approximates experimental numbers and theoretical numbers. 2) The relationship between M_2 and M_3 profile is comparatively approximated to experimental numbers and theoretical. In which the authorization results of Flow channel (by IDA) are excellent.

Objectives : This study is to suggest a kind of guide line of dietary therapy in allergic diseases. Methods : We investigated frequency, symptoms and implicating foods of food allergy, and experience, methods, periods, results and necessity of dietary therapy of 49 patients with allergic diseases by using self-report questionnaires. The data were analyzed by SPSS/PC+ program using frequency, Chi-square test(p〈0.05) and Pearson correlation coefficient(p〈0.01). Results : 1. The frequency of food allergy was 49% and skin symptoms were the most common. 2. The most implicating foods were chicken, flour, milk, pork and egg in order. 3. 36.7% of patients had experienced dietary therapy and 47.4% of them had stated mild improvement. 4. Over 80% of patients perceived necessity of dietary therapy and there is significant correlation between necessity of dietary therapy and sum of food allergens(r=368). Conclusions : Dietary therapy is recommended as supplementary therapy in allergic diseases and it needs to be established based on the real conditions and Korean Oriental medical theory.

Objective: This study was designed to investigate clinical features of chronic urticaria and assess Korean traditional medical therapy on that. Methods: The ratio of male and female, duration of symptoms, personal history and family history of allergic diseases, serum IgE level, and suspected causes and provocation factors were investigated in 41 patients with chronic urticaria. And frequency of wheals, duration of wheals, number of wheals, itch severity, and antihistamine counts of 6-point(0-5) score was assessed in 26 patients. The change of total scores between baseline and follow up were analyzed using Wilcoxon signed-rank test(p〈0.05). Results: 1. The ratio of male and female was 1:1.28 and the mean duration of symptoms was 26.0 months. 2. The frequency of personal history and family history of allergic diseases was each 53.7$\%$ and 48.8$\%$ and 30.6$\%$ had over 200 IU/mL serum IgE level. 3. The suspected causes were none(43.9$\%$), foods(29.3$\%$), drugs(9.8$\%$) and stress(7.3$\%$). 4. The suspected provocation factors were foods(39.0$\%$), none(19.5$\%$), fatigue(17.0$\%$), heat and sweating(l4.6$\%$), pressure(12.2$\%$) and stress(9.8). 5. The total scores between baseline and follow up of 26 patients was lowered from 14.85${\pm}$3.80 to 7.65${\pm}$4.31 and it was significant statistically. Conclusions: Korean traditional medical therapy was proved to be effective on the chronic urticaria and we need to consider foods as important factor in both treatment and patient education of urticaria.
