We investigated springs in Seoul in 2009 to know the change of water quality according to storage method of spring water, the concentration of chemical compounds and their correlation. Even spring water that originally satisfied national standard for drinking water could be exceeded national standard for drinking water by storage method such as storage bottle, temperature and period; especially used PET bottles could affect the increase of total colony counts. Therefore, spring water is desirable to be consumed on the spot, or to be stored in sterilized bottles in refrigerator rather than room temperature at home, and also to be consumed shortly not exceeding 24 hours. Total colony counts, coliform, yersinia, $F^-$, $Cl^-$, $NO_3^--N$, hardness, total Solids, pH, color and Al were exceeded national standard for drinking water at some springs. The result of correlation analysis shows that hardness and total solids, which are caused by several ionic compounds, had relatively high correlations with other chemical compounds.

본 논문에서는 통계적 역문제로서 이항 선택모형에서의 밀도추정 방법에 대하여 연구하였다. 밀도함수의 추정을 위하여 직교열 기저를 이용하였으며, 모형의 복잡성과 예측의 정확성을 반영한 적절한 절단모수의 선택에 대하여 고려하였다. 이항 선택 모형에서 데이터에 의존하는 절단모수를 선택하는 방법에 대해 제안하고 모의실험, 실자료를 통해 제안한 방법의 성능을 규명하였다. This paper deals with a density estimation method in binary choice models that can be regarded as a statistical inverse problem. We use an orthogonal basis to estimate density function and consider the choice of an appropriate truncation parameter to reflect the model complexity and the prediction accuracy. We propose a data-dependent rule to choose the truncation parameter in the context of binary choice models. A numerical simulation is provided to illustrate the performance of the proposed method.

We surveyed the citizens opinion about springs in Seoul for two years from 2008 to 2009. It was found that spring water was mostly used by citizens older than 50, and that 29.5% of citizens used purified tap water as drinking water, 27.2% of them used boiled tap water, 21.1% of them used spring water, and 12.1% of them used bottled water. Citizens who store spring water more than a day are 76.7%. Although many citizens (70.3%) knew that water quality had been tested, 40% of them didn't care about checking the certificate of water quality analysis. Once recognized that the spring water was unfit for drinking exceeded standard of drinking water, 85% of citizens would rather not use the spring water.

원격탐사자료를 이용한 서울시 토지피복의 시계열 변화량 추출
김광래(Kim Kwang-Rae),이종성(Lee Jong-Sung) 대한국토·도시계획학회 1998 國土計劃 Vol.33 No.3
The study attempted to extract information about such detecting change in the land cover of Seoul using time series data of remote sensing as basic data in landscape planning using a landscape ecological approach. For this purpose, we performed a classification of land cover after geometric collection using 5 scene of Landsat MSS data : 1979, 1983, 1988, 1992, 1996 for a change detection of each land cover. We also tried to compare the results of classification with statistical year book of Seoul to form an analysis of correlation tendencies. The results are as follows : First, there was little diffrence between the result of classification and statistical data in the degree of correlation tendencies except for water body. Second, urban areas expanded agricultural areas and the peak of the increasing degree was from 1979 to 1983, specifically, 60.63㎢. Third, we could find that the agricultural land was transformed to urban land through existing barren land by investigating the spatial pattern on the changing process of image map classified. Fourth, the area of spatial distribution of forest land which was changed to urban land mainly occurred at Nowon-gu, Dobong-gu and Mapo-gu in Kangnam area. Also Kangdong-gu, Songpa-gu, Kangnam-gu and Guro-gu, Yangchon-gu in Kangbuk area experienced changes from 1979 to 1996. Fifth, Considering the changing of the forest land that was 46.52㎢ in Seoul, we need to consider the loss of biological diversity because of the fragmentation of forest land in landscape planning through an ecological landscape approach.

노인 남성들의 기능적 체력, 신체구성, 혈압과 발기능력과의 관련성
김광래 ( Kwang Rae Kim ) 한국운동생리학회(구-한국운동과학회) 2010 운동과학 Vol.19 No.2
본 연구의 목적은 건강한 남성 노인 37명을 대상으로 하여 기능적 체력, 신체구성, 혈압과 발기능력과의 관계를 규명하는데 있다. 전체적인 발기능력은 국제 발기능력 측정 설문지의 15개 문항중 1번 문항부터 6번 문항의 점수를 합산하여 설정하였으며, 발기성취력은 3번 문항의 점수로, 발기유지력은 4번 문항의 점수로 설정하였다. 기능적 체력은 6분 걷기, 30초 앉았다 일어나기, 1분 앉았다 일어나기로 평가하였으며, 신체구성은 생체 전기 저항 분석법을 적용하여 분석하였고, 혈압은 자동혈압계를 이용하여 분석 하였다. 상관관계 분석 결과 전체적인 발기능력, 발기성취력, 발기유지력과 6분 걷기, 30초 앉았다 일어나기, 1분 앉았다 일어나기 간에 통계적으로 유의한 상관관계가 있는 것으로 나타났으나, 신체구성과 혈압간에는 유의한 상관관계가 없는 것으로 나타났다. 그리고 관련성이 있는 변인들을 독립변인으로 하여 다중회귀 분석을 실시한 결과 전체적인 발기능력, 발기성취력, 발기유지력에 가장 영향력이 있는 변인은 6분 걷기로 나타났다. 결론적으로 남성 노인들이 기능적 체력이 높으면 높을수록 전체적인 발기능력, 발기성취력, 발기유지력이 높아질 수 있을 것이라고 판단되며, 기능적 체력 요인 중 가장 영향력이 큰 요인은 심폐지구력이라고 할 수 있다. 따라서 규칙적인 유산소성 운동을 통한 심폐지구력의 증진은 남성 노인들에게 있어서 나타날 수 있는 발기능력의 저하를 예방 혹은 지연 시키는데 있어서 중요한 역할을 할 수 있을 것이라고 사료된다. This study was to examine the relationship of functional physical fitness, body composition, blood pressure, and erectile capacity in 37 healthy old men. Overall erectile capacity were evaluated in sum score(Q1-Q6) by IIEF questionnaire, erectile achievement capacity were evaluated in score(Q3) by IIEF questionnaire, and erectile maintenance capacity were evaluated in score(Q4) by IIEF questionnaire. Functional physical fitness was measured by 6 min walking, 30s-sit to stand, 1 min-sit to stand and body composition assess by bio impedance analysis, blood pressure was measured using an automated blood pressure monitor. Overall erectile capacity, erectile achievement capacity, erectile maintenance capacity was significantly related to the 6 min walking, 30s-sit to stand, 1min-sit to stand but not body composition, blood pressure. In stepwise multiple regression analysis with the 6min walking, 30s-sit to stand, 1 min-sit to stand as the independent variable, only 6 min walking was identified as a significant variable for overall erectile capacity, erectile achievement capacity, erectile maintenance capacity. In conclusion, as old male men with higher functional physical fitness showed greater overall erectile capacity, erectile achievement capacity, erectile maintenance capacity and the influence factor of among functional physical fitness is cardiovascular endurance. So, it is suggested that a cardiovascular endurance may play important role in preventing or delayed the decline of erectile capacity in old men.
