이길영 大田工業高等專門學校 1971 論文集 Vol.7 No.-

하천형상에 대하여 그 방향은 하천지형학(Potamological)적인 부분을 중심성으로 해서 연구코자 하오며, 우리 나라 면적의 1/4에 해당하는 낙동강 유역의 지형적인 특성을 현지답사(現地踏査)와 참고문헌과 여러가지 자료를 사용해서 조사 검토 하였는데 특히 각 수위표지점(水位標地點), 합류지점(合流地點), 수력지점(水力地點) 및 범람평원 등은 현지답사를 해서 도표작성으로 특성을 구명(究明)했으며 유로연장(流路延長), 유역면적(流域面積)은 U. S. A Army Map Scale 1;50,000에서 축척으로 측정하고 참고 자료와 비교해서 얻어진 것으로 하천의 평균폭, 하천형상 계수, 하천밀도를 계산했으며 평균고도(平均高度) 1;50,000 지도상에서 얻어서 각 유역의 특성을 나타내었다. 이와 같이 보다 이론적인 근거하에서 과학적으로 조사 검토한 결과 본 유역 면적의 대소와 대소 지류(支流)의 배치가 방사선상(房射線狀)과, 우상(羽狀)의 혼합으로 되어있다는 것과, 1km당 315m길이의 하천이 놓여 있다는 것, 불양배수류(不良排水流)이라는 것, 포물선(抛物線)에 가까운 평균종단곡선(平均縱斷曲線)을 이루고 있다는 것을 알았다. 위와 같은 기본 연구로써 洛東강 유역 개발에 적용코자 한다. This present writer, I have brought hight to at study for river-situation at about potamological characteeristic. As to the topoaraphical traits of NAK-DOfG river basin to be coresponded with one fourth 1/4 of the whole area of our country, I have studied with the detail investigation through the exploration, reference books site and some other studying materials. As a result of such researches, particularily for the each water-gauge, a confluence site, hydro-power site and flood plain and etc, I have brought light to study the special guality with the list of drawing as the result of site exporation with checking of crosscut figure andall uvial cone. For the length of river and the area of river, they have been measured with U. S. A army map scale 1:50,000 compared with the soures of conference, the average width of river, the shape factor of river and river density were calculated and the average higher altitude was measured as 1:50,000on tile map, and that the relation between the average altitude and distance has been appeared with each river basin traits after there abtaind by the crosscut lines. Beside this, some ather items of subject has been brought light on a study, making the mostof use with a known reports and a liburary books of reference. As of the above descriptions, under more further reasonable and theoretical bases, this river basin has been reconsidered to study scientificallly and its results are as follows; This consists of the large and small of main river area and the dispatch of branch river is made of conbined radial form and pinnate form. The each river covers one square ㎢ for the length of 315 meters. This is belonged a kind of bad swearage for a swift stream. It means to be composed with average vertical section parabola with the above results, I here by would like to apply to the development of NAK-KONG river basin.

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.

Generally, stress brings about dark skin color, dry skin, or skin resistant to cosmetic application. The relation between stress and skin color or moisture tends to be viewed in these terms. However, there are only few reviews of relations between skin color and moisture as well as these factors. This study reviewed relations between mental and physical stress in daily life and changes in skin color and moisture by measuring stress level and skin color and moisture of healthy women aged 20~40 living in Seoul and Gyeonggi areas. The review took place five times on the first day, after 7 days, 15 days, 1 month, and 2months. The results are as follows. First, the test subjects showed significantly higher stress levels on the first day compared to other test dates and the skin color level increased in the same significant way. However, on the 15th day, stress level and skin color level decreased. Second, on the 15th day when stress level was lower, skin moisture significantly increased. Third, stress level of female subjects in their 20s,30s, and 40s significantly increased on the first day of measurement and significantly fell on the 15th day. As for color levels, those in their 20s, 30s, and 40s increased significantly on the first day of measurement and fell on the 15th day of measurement. As for skin value and chroma, there was no significant difference by age. Skin moisture on the 15th day of measurement was significantly higher than those of other measuring points of time and significantly lower skin moisture on the first day of measurement than other measurement days. The results of this study clarified that physical and mental stress certainly affected skin color and moisture of women aged 20~40.

This study is intended to provide the effective treatment methods of sediments of the polluted and water resources in Geum River reservoir. its ultimate purpose is the water management and protection of the water quality and water resources. Geum River reservior and main river were selected as investing objects for this purpose. estimated were the amount of organization ratio and heavy metals in the sediment of dam reservior and main river. In case of Geum River reservior, delta of three areas i.e. A area (A), B area (B), C area (C) were selected to estimate the amount of sediment.(Fig 3.2, Photograph 4.1) Sieve analyer of the sample sediment taken from the above sites shows that the sediment is composed of 87∼89% of sand, 7∼9% of silt and 4% of clay. The trace amount of heavy metals found of in the sediment of Geum River reservoir (delta of three areas) was considered lot of heavy metals such as Zn, Pb, and Cr are exists, due to hydraulics and geological characteristics the dam area. In case of treatment methods of sediment, dredging, chemical treatment and hydrological operation are discussed for the treatment of sediment in Geum River reservoir.
