Currently, item about legislation and regulation about sea area is unprepared and it is family circumstances that study finding is very badly off yet in reply. And cadastral connection item is bery sensitive segment part because that is item connected with manus. This is part cause a lot of processing of dispute by difference of pros and cons between local government is arisen in whole country every where. However, it is mutual agreement or real condition been settling by method by control of technique of law and government between each other by unpreparedness of technological member and connection legislation. In this study, arranged about cadastral boundary delimitation an investigate Gadeokdo Island about satellite image and boundary that is fixed on NGII(National Geographic Information Institute) of digital map laying stress on new port. And, that use GPS survey satellite image in technological member urgently computerize should.

In order to provide the basic information for the water quality of urban streams and the quality variation of these streams, the water pollution indicators of Sin stream and Keumho river flowing through Taegu city were measured, and the variations of COD and OC of stream waters and artifical samples were studied under the condition of stagnation. For this experiment, two sampling sites(Sungpook bridge, Mutae bridge) were selected. Sungpook bridge is located most down the Sin stream, Mutae bridge is located on the lower keumho river. Artificial samples were prepared with mixing starch and CaCl?, and the pHs of these samples were adjusted by adding NaOH and HCl. The results were as follows. 1. The DO values of stream waters sampled in June and July were much lower than those of stream waters sampled in March and April. 2. The COD values of all the samples highly exceeded the fifth grade of environmental criterion(10mg/?) 3. EC highly correlated with ALK and Cl anion. 4. The COD values of stream waters sampled in June and July and stagnated under the laboratory temperature distinctly decreased in process of stagnation, and those of stream waters sampled in April and stagnated in the incubator(20℃) also distinctly decreased. But, the COD variations of stream waters sampled in March and April and stgnated under the laboratory temperature didn't show a distinct tendency. 5. The contents of OC in stream waters sampled in March and April and stagnated under the laboratory temperature distinctly decreased in process of stagnation, and those of stream waters sampled in April and stagnated in the incubator(20℃) also distinctly decreased. But, the contents of OC in stream waters stagnated under the incubator temperature, which was higher than the laboratory temperature, more rapidly decreased in process of stagnation.

박병윤,이부용 대구효성가톨릭대학교 응용과학연구소 1997 응용과학연구논문집 Vol.5 No.-

하양읍을 관류하여 금 호강으로 유입되는 소하천들과 하양읍의 남쪽 외곽을 흐르는 금호강을 대상으로 10개 지점을 선정하여 시기별로p 인(PO_4-P), 화학적산소요구량(COD), 경도(hardness) 및 Cl 이온을 조사한 결과는 다음과같았다. 1) 월별 pH값의 변동범위는 1월에는 7.3~82. 2월에는 7.O~8.2, 3월에는 6.9~ 8.9, 4월에는 7.5~9.3, 5월에는 6.3~7.9이었다. 3월부터 하천수의 pH는 상승하기 시작하여 4월 하천수의 경우에는 pH가 가장 높았다. 그러나 수온이 매우상승하는 5월 하천수의 pH는 가장 낮게 나타났다. 2) 월별 경도의 변동범위는 1월에는 14~71mg/l, 2월에는 14~70mg/l, 3월에는 13~66mg/l, 4월에는 11~55mg/l, 5월에는 16~100mg/l 이었다. 전체적으로 경도는 하천 하류지점으로 갈수록 증가 하였으며, 그리고 하양읍을 관류하는 소하천의 경우 5월 하천수의 경도가 보다 높았다. 3) 월별 인(PO_4-P)의 함량은 1월에는 0.55~l.10mg/l, 2월에는 0.80~1.38mg/l, 3월에는 0.40~0.70mg/ㅣ, 4월에는 0.25~0.50mg/ㅣ, 5월에는 0.35~1.06mg/ㅣ 이었다. 지점별로는 하양시 장지역 의 생활하수가 직접유입되는 S6(Hajubridge Ⅱ)지점에서 특히 인의 함량이 높았다. 이는 타 주거지역 보다 시장지역에서 오염물질의 배출량이 많기 때문으로 사료된다. 4) 월별 COD값은 1월에는 특히 높은 S6(Haju bridge Ⅱ)지점의 19.5mg/l를 제외하면1.O~ 6.5mg/l, 2월에는 22.O~27.5mg/l, 3월에는 21.5~24.8mg/l, 4월에는 21.5~27.Omg/ l, 5월에는 23.5~39.Omg/l이었다. 그리고S6(Haju bridge Ⅱ)지점에서의 COD값은 타지점보다 높은데, 이는 인 함량의 비교에서 나타난 것과 같다. 5) 월별 Cl이온의 양은 1월에는 12.O~46.5mg/l, 2월에는 15.0~46.Omg/l & 3월에는 11.5~36.Omg/l, 4월에는 11.5~75.Omg/l, 5 월에는 16.O~95.Omg/l이었다. 지점별로는S6(Haju bridgeⅡ)지점에서의 Cl이온의 양이 타 지점보다 높은데, 특히 5월 하천수의 Cl이온의 양이 크게 높았다. This study was conducted to provide the basic information for the effective purification of town streams in Hayang-up and the conservation of Keumho river. Periodically, pH, hardness, phosphate(PO_4-P), COD and Cl anion of water were investigated at ten sampling sites. The results were as follows. 1) The range of pH values, which were measured in January, February, March, April and May, were 7.3∼8.2, 7.0∼8.2, 6.9∼8.9, 7.5∼9.3 and 6.3∼7.9 respectively. 2) The ranges of hardness values, which were measured in January, February, March, April and May, were 14∼71mg/ℓ, 14∼70mg/ℓ, 13∼66mg/ℓ, 11∼55mg/ℓ and 16∼100mg/ℓ respectively. 3) The ranges of phosphate values, which were measured in January, February, March, April and May, were 0.55∼1.10mg/ℓ, 0.80∼1.38mg/ℓ, 0.40∼0.70mg/ℓ, 0.25∼0.50mg/ℓ and 0.35∼1.06mg/ℓ respectively. 4) The ranges of COD values, which were measured in January, February, March, April and May, were 1.0∼19.5mg/ℓ, 22.0∼27.5mg/ℓ, 21.5∼24.8mg/ℓ, 21.5∼27.0mg/ℓ and 23.5∼39.0mg/ℓ respectively. Especially, the COD values measured for five months at Haju bridge Ⅱ(market area) were at range of 19.5(Jan.)∼39.0(May)mg/ℓ, these values were very high in comparison with those measured at other nine sampling sites. 5) The ranges of Cl anion values, which measured respectively in January, February, March, April and May, were 12.0∼46.5mg/ℓ, 15.0∼46.0mg/ℓ, 11.5∼36.0mg/ℓ, 11.5∼75.0mg/ℓ, and 16.0∼95.0mg/ℓ. The Cl anion values measured at Haju bridge Ⅱ(market area) were also much higher than those measured at other sites.

본 연구에서는 전통적으로 우리 식탁의 주요 부식으로 이용되어온 콩나물과 미나리를 Cd와 Pb가 함유된 배양액으로 재배하는 동안 이들 채소에 Cd와 Pb 가 어느 정도 흡수되는가를 조사하였다. 또한 수경재배에서 Cd와 Pb에 의한 콩나물의 생육장해 정도를 조사하였다. 배양액속에 함유된 Pb이온은 재배기간 동안 미나리와 콩나물 체내로 쉽게 흡 수되었다. 그리고 미나리는 콩나물보다 더 많은 양의 Pb를 흡수하였는데, 이 는 미나리의 줄기에 다량의 뿌리가 붙어있기 때문인 것으로 생각된다. 또한 배양액속의 Pb의 농도와 미나리와 콩나물 체내에 축적된 Pb의 함량과는 높은 상관성을 나타내었는데, 각각의 상관계수(r^2)는 0.9411, 0.9828이었다. Cd역시 Pb와 마찬가지로 재배기간 동안 미나리와 콩나물 체내로 쉽게 흡수되 었다. 또한 배양액속의 Cd의 농도와 미나리와 콩나물 체내에 축적된 Cd의 함 량과는 높은 상관성을 나타내었는데, 각각의 상관계수(r^2)은 0.9900, 0.9054이었다. 그러나 두 식물체에서 Pb의 흡수 경우와는 달리 배양액속에 함유되어 있는 Cd의 농도가 높을 경우 콩나물이 미나리보다 더 많은 Cd을 흡수하였다. 콩나물의 경우에는 Cd과 Pb이 재배기간 동안 거의 비슷한 양으로 흡수되었으며, 그리고 배양액 속에 함유된 이들 중금속들과 콩나물 체내에 축적된 중금속들 사이의 직선회귀선의 기울기도 거의 유사하였다. 그러나 미나리의 경우에는 Pb이 Cd보다 상당히 많은 양이 흡수되었으며, 또한 직선회귀선의 기울기도 Cd보다 Pb의 경우 상당히 크게 나타났다. Cd와 Pb의 농도가 1mg/l일 경우에는 콩나물 길이의 성장 또는 외관상의 생육에 거의 영향이 없었다. 그러나 10mg/l 농도에서부터는 길이의 성장장해뿐만 아니라 외관상으로도 분명한 장해현상이 나타났다. 50mg/l와 100mg/l의 농도에서는 콩나물의 생육장해가 더욱 심해졌다. Pb의 경우에는 100mg/l의 농도에서, Cd의 경우에는 50mg/l의 농도에서부터 재배기간 동안 콩나물의 상당 부분이 썩는 현상이 나타났다. This study was conducted to investigate the uptake of Cd and Pb by vegetables. Bean sprout and dropwort, which are very important for traditional korean dishes, were cultivated in culture fluid added with Cd and Pb cations, and the content of Cd and Pb absorbed by these vegetables were measured. Pb cations in culture fluid were easily absorbed into bean sprout and dropwort. And dropwort absorbed Pb more than bean sprout did. Pb contents of bean sprout and dropwart dramatically increased with increasing Pb concentration in culture fluid. The correlation coefficients(r^2) between Pb contents in dropwort and bean sprout and Pb concentrations in culture fluid were 0.9411 and 0.9828, respectively. Cd cations were also easily absorbed into bean sprout and dropwort. The correlation coefficients(r^2) between Cd contents in dropwort and bean sprout and Cd concentrations in culture fluid were 0.9900 and 0.9054, respectively. The growth of bean sprout was not hindered at the concentration of 1mg/ℓ Cd and Pb in culture fluid. But high Cd and Pb concentrations hindeded remarkably the growth of this vegetable. A large part of bean sprout was rotten at the concentrations of 50 mg/ℓ Cd, and 100 mg/ℓ Pb.

로버스트 능형회귀 추정법

김부용,박형숙 숙명여자대학교 자연과학연구소 1999 자연과학논문집 Vol.- No.10

회귀분석을 위한 자료에는 회귀이상점이 포함되어 있으며, 동시에 다중공선성이 존재하는 경우가 있다. 이상점들만 포함되어 있는 경우에는 로버스트 추정법을 적용할 수 있으며, 다중공선성만 존재하는 경우에는 능형회귀 추정법을 적용할 수 있다. 그러나 회귀이상점과 다중공선성은 상호 관련을 가지므로 어느 한 문제만을 해결하는 것은 완전한 것일 수가 없다. 따라서 회귀이상점과 다중공선성이 동시에 존재하는 상황에서의 효과적인 추정 방법을 제안하고자 한다. Statisticians have suggested many methods for the problems of multicollinearity and outliers seperately. However, we usually encounter many data sets which have both problems. Thus, we propose a procedure that is called the robust ridge estimation and is very effective to deal with the problems simultaneously. The proposed procedure employs the LMS estimate to determine the bias parameter of ridge regression. In addition, it is verified by simulation studies that the proposed iterative method is more effective, in terms of the stability of estimates and squared distances, than the existing procedure based on the least squares estimates.

We have analyzed this influence base on survey of central government administration officers and local officers which were taken on 2001 and 2003. Also, we anticipates that this result would help actual field adjustment as well as preparation of speciality of officers. The results are summarized as follows : First, a survey in 2001 shows 68.8 percent of local administration officers answered that their expertise about environmental services were above average. Then, the result was increased to 82 percent of officers responsed that they have more than average expertise and experience in 2003 survey. Secondly, government have to increase effectiveness on regulation or restriction duty. Nonetheless, the survey shows that significant decrease of effectiveness from 2001 to 2003 in both central and local goveniment officers. It means that they spent more effort on local community environmental regulation program other than restriction duty to requisited from central government. Third, moreover, local government do not want to faculty of environmental administration and insists that governments need to set the regulation for particularity of regions.
