農業用水에 對한 小考

黃龍鎭,李裕根 진주산업대학교 1982 論文集 Vol.20 No.-

This paper is the one with relation to the agricultural useful water, and then I inquired about the vestiges of the water supply constructs in order to control by the our ancestors. Total consumption water quantities were 1144.24mm as a result of investigated to the consumption water quantities in the rice farming. It is 149 hundred millions ㎥ that is necessary for our country now, therefore, we have need for more water than being. A devise of resolving to the problem belongs to de promoting of the water holding in the soil and the construction of multiple dam.

適正 確率降雨度式 算定에 關한 考察 : 晋州地方을 中心으로 On Jinju Area

黃龍鎭,金羽中 진주산업대학교 1984 論文集 Vol.22 No.-

This study was carried out to find most suitable formulaas for prabable rainfall intensities to the return periods in regard to it with analysis for charateristics of short­term (30.60.120.180.360 minutes) rainfall intensities according to the return periods at JinJu district. Above mentioned formulas induced by study can he contributed to the calculation of runoff meaeurenents for urban sewerage system and a small drainage basin. The results of this study are summarized as follows. 1. Standard diviation of Japenese type came out as the most small value for 1.41∼1.97 among the probable rainfall intensity formulas. 2. Standard diviation by the precision method were less than that by the specific coefficient method. 3. The most suitable probable rainfall intensity fomulas for the return periods at JinJu district, It is as table 4.

黃龍鎭 진주산업대학교 1998 산업과학기술연구소보 Vol.- No.5

In Gyingnam province(Chinju, Milyang), the evapotranspirations used meteorological data during 5 years from 1993 to 1997 were investigaed for 8 months(from March to October) which crops brought up, and the evapotranspirations estimated by Blaney & Criddle method and Radiation method in each a period of ten days and each month showed table 2 and table 3. The required water of crops was able to calculate to multiply by the coefficient of crops which used the evapotranspirations. Blaney & Criddle method was considered as the formula recommended in Gyengnam.

In this study, with a purpose to establish the standard construction contract conditions, the FIDIC conditions of contract and ther corresponding legal systems from the various domestic laws and regulations, used as the construction conditions, were compared. The study shows problems such as inconsistence and atypicality between current provisions and FIDIC contract. The possibility of claim occurrence in Korea construction market is significant. Through a comparison of domestic and foreign construction contract, the study presents that domestic contracts don't have provisions about the procedure of submission, engineer's responsibility and authority, and effective procedure of claims. The study also presents techinical considerations under the FIDIC Contract by Employer and Contractor.

황용진 진주산업대학교 건설기술연구소 1998 건설기술연구소보 Vol.1 No.-

Since 1997, the Korean Government has increasingly introduced CM(Construction Management) system which is a new project delivery system, with the opening of the construction market. In case of Korea, not only the applicable criterion of CM but also definition of that has not still established. This study aims to minimize trial and error that may occurre when CM is applied to the domestic construction by examining the background and progress of the American CM system. Consequently, in this study, proper method to apply CM to this country is suggested by synthesizing CM business standards of GSA and other organization and analyzing the role and responsibility of CM

밭作物의 灌漑用水量 算定 : 大豆를 중심으로 for Soybean

황용진 진주산업대학교 건설기술연구소 1998 건설기술연구소보 Vol.1 No.-

This study was carried out to determine the optimum irrigation level for upland crops especially soybean through the analysis of their evapo-transpiratiion, growth and yield. The optimum irrigation level for each upland crop will enable us to calculate the project irrigation requirement for a design year. In this study, two varieties of soybean, Milyang 31 and Eunha, were cultivated in lysimeters in the farm of Chinju National University. The levels of irrigation were 29-26%, 25-22% and 21-18%, respectively. The soil moisture contents were maintained within a narrow range. From the experiment and analysis, the conclusions are derived as followings; 1. The numbers of branches, main stems and pods per plant, and the 100-grain weight of Milyang 31 and Eunha tended to increase as the irrigation level were changed from 21∼18% through 29-26% to 25-22%. 2. As the optimum irrigation level og 25-22%, the daily average evapo-transpiration of Milyang 31 and Eunha were 3.21㎜/day, 3.25㎜/day. The total evapotranspirations of Milyang 31 and Eunha were 276.23㎜, 312.11㎜. 3. The effective of the rainfall in the design year was 57.76% in case of Milyang 31 and 50.35% in case of Eunha. The net project irrigation requirements of Milyang 31 and Eunha were 288.23㎜ and 281.36㎜ respectively. 4. The intermittent irrigation days of both Milyang 31 and Eunha were calculated as 4days. The net irrigation requirement at a time was calculated as 28.72㎜, 29.04㎜ respectively.

本 硏究는 土壤水分을 正確하게 測定하기 위한 貫入用 Sensor 開發을 目的으로 實施하였다. 貫入用 Seosor는 圓簡形 銅管사이에 絶緣材를 揷入하여 만들었으며 이 Sensor를 土壤에 貫入하여 土壤水分含量에 따라 변화는 銅管 양측의 電氣抵抗을 測定하므로서 土壤水分을 알 수 있게 하였다. 實驗結果는 電氣抵抗値는 Sensor의 直徑이 적을수록 絶緣材 間隔이 클수록 증가하였으며 測定誤差는 直徑차이에 관계없이 絶緣材 間隔이 13mm에서 적었고 Sensor의 直徑 12.6mm, 絶緣材 間隔 13mm인 것이 비교적 양호하였다. 또한 電氣抵抗値는 土壤含水率이 커짐에 따라 指數函數的으로 減少하였고 Mc=aR^-b의 形態로 나타났다. 대부분 Sensor가 指數 b의 값이 크게 나타나 直線性이 양호하지 못하였고 標準誤差의 값도 크게 나타났으며 土壤水分 10%以下와 30%以上에서는 정밀한 計測이 어려울 것으로 생각된다. This study aimed at developing an interpenetrated sensor for exact measurement of soil moisture. The interpenetrated sensor was a cylindrical Cu-pipe with insulation gap in the middle when this sensor was interpentrated into the soil, the electric registance value of both ends of the Cu-pipe changed according to the moisture content of the soil. The soil moisture content could be measured by the change of electric registance value. The results were as follows : As the diameter of sensor was smaller and the insulation gap was larger, the electric registance value increased. The measurement error was small in the case of 13mm insulation gap irrespective of the sensor diameter and smallest in the case of 13mm sensor diameter and 13mm insulation gap. As the soil moisture content increased, the electric registance value decreased exponeutially. Their relation was found to be MC=aR^-b. The value of exponent b and the standard error was great in most sensors. Their graphs didn't show straightness and the exact measurement of soil moisture content was difficult in the range below 10% and above 30% of soil moisture content.

晋州地方을 중심한 남부지방의 50년(1926∼1976)간의 降雨現象을 分析한 結果 다음과 같은 결론을 얻었다. 1. 우리나라 年平均 降雨量(1159㎜)보다 많은 편(1385.8㎜)이나 1日 最多降雨量은 다른 지역보다 적은 편에 속한다. 2. 降雨量의 約 60%가 6월∼9월에 集中 降下하고 있었다. 3. 確率日降雨量 計算은 4가지 모두 비슷한 결과를 보이고 있다. 4. 50年間의 觀測資料를 분석한 결과이므로 그 信賴度가 높을 것으로 본다. The results which had been analyzed to a rainfall phenomenon in the southern district centering around with Chinju area for 50 years, obtained results were as follows. 1. This results is estimated as higher than the average year rainfall of Korea : but the maximun daily rainfall is observed as smaller than other districts. 2. It rains between Jun-August about 60 percentage of amount of rainfall. 3. Caculation of assumed value of probability of daily precipitation is analized as a similar result all of four varieties. 4. With observed data for 50 years, It seems that degree of confidence is very high.
