  • 소양호로 유입되는 유기탄소량을 측정하였으며, 유기탄소 부하량에 대한 유기물 기원의 기여도를 계산하기위해서 내부생성유기탄소와 외부기원유기탄소를 측정하였다. 내부생성유기탄소는 EOC를 고려한 식물플랑크톤의 1차생산력으로부터 계산하였으며, 외부기원유기탄소는 유입수의 유기탄소 농도와 양어장의 유기탄소 배출량으로부터 구하였다. 1차생산력은 가두리 양식장이 설치된 1987견부터 증가하여 1995견가지 높은 분포를 보였으며 가두리가 철거된 1998년 이후 급격히 감소하였다. 내부생성유기탄소와 외부기원유기탄소의 부하는 여름철에 집중되었으며, 7${\sim}$9월에 연간 부하량의 43.2%와 71.7%가 각각 유입되었다. 1차생산력은 여름철에 $1,000\;mgC\;m^{-2}\;d^{-1}$ 이상으로 증가하였으며 겨울철에 비교적낮았다. 식물플랑크톤의 EOC배출율도 1차생산이 증가하여 수체의 DOC농도가 높은 여름철에 높았다. 전체조사기간동안 내부생성과 외부기원유기물의 평균적인 기여도는 각각 총부하량의 53.6%와 46.4%를 차지하였다. EOC 배출율은 1차생산력의 4.4${\sim}$21.2%를 차지하였으며, 1차생산력 산정에서 식물플랑크톤의 EOC 배출율이 고려되어야 할 것으로 보인다.

  • Abstract A study on the Derivation of the Unit Hydrograph using Multiple Regression Moe이. The purpose of this study is to deriver an optimal unit hydrograph suing the multiple regression model, particularly when only small amount of data is available. The presence of multicollinearity among the input data can cause serious oscillations in the derivation of the unit hydrograph. In this case, the oscillations in the unit hydrograph ordinate are eliminated by combining the data. The data used in this study are based upon the collection and arrangement of rainfall-runoff data(1977-1989) at the Soyang-river Dam site. When the matrix X is the rainfall series, the condition number and the reciprocal of the minimum eigenvalue of XTX are calculated by the Jacobi an method, and are compared with the oscillation in the unit hydrograph. The optimal unit hydrograph is derived by combining the numerous rainfall-runoff data. The conclusions are as follows; 1)The oscillations in the derived unit hydrograph are reduced by combining the data from each flood event. 2) The reciprocals of the minimum eigen\value of XTX, 1/k and the condition number CN are increased when the oscillations are active in the derived unit hydrograph. 3)The parameter estimates are validated by extending the model to the Soyang river Dam site with elimination of the autocorrelation in the disturbances. Finally, this paper illustrates the application of the multiple regression model to drive an optimal unit hydrograph dealing with the multicollinearity and the autocorrelation which cause some problems.

  • 1. Introduction Community medicine with the concept of comprehensive medical care and an ideal medical care delivery system not only for an individual or family but for the whole community has emerged. In April 1970, the Presbyterian Medical Center started a hospital based community health service project in order to improve the health of the people in rural areas. Prior to commencing a comprehensive medical care system, a family survey was needed. The major objective of this survey was to obtain information concerning the people and their environment so as to be able to plan and implement a comprehensive medical care program in Soyang-Myun. 2. Survey Method An interview using a family record form was carried out for each household. This family record form was designed to get information about demography, family planning, environmental sanitation and vital statistics. Prior to beginning, the members of the survey team were trained in interviewing techniques for three days. The team consisted of a public health nurse, four nurse-aides, a sanitarian and four health extension workers who are working in our project, The survey was carried out during the period November 1971 to March 1972. 3.

  • This study aims to compare and analyze somatotype characteristics in clothing ergonomics as well as Sasang (Oriental physical constitution type classification into 4 kinds: taeyang, taeeum, soyang, soeum) medicine. The subjects were women collegians in their 20s. As a result, a new approach was made in somatotype classification. The following are conclusions: 1. The results of body measurement of the subjects belonged to 1 in most items when they were compared with the average records of female adults in their 20s in the national standard physique report. Thus, the subjects belonged to the average somatotype. 2. According to Sasang physical constitution classification, no subjects belonged to taeyang-type. Taeeum type (28.4%), had lower-body development greatest height and even development in width, thickness and girth. Soeum-type(37.8%) had the smallest physique. Soyang-type(33.8%) showed small values in height but great values in width, thickness and girth. 3. The factor analysis revealed 5 factors of somatotype characteristics: lower body factors including body weight, upper body factors, height factors including stature, belly width factors including waist and belly, and other factors comprising ankle and head size. 4. A cluster analysis by way of factor scores resulted in 3 types: cluster 1 44.6%, biggest values, largest somatotypes; cluster 2 17.6%, average somatotypes; cluster 3 tiniest somatotypes in most items. 5. In the crosstabs analysis, taeeum-type (57.6%) appeared a lot in cluster 1, soyang-type (76.9%) appeared most in cluster 2, and soeum-type (69.9%) was mostly seen in cluster 3. To sum up, the somatotype analysis of clothing ergonomics had something to do with constitution classification suggested in Sasang medicine. For clear justification, more systematic and scientific research should be followed with even more diverse subjects in sex and age.

  • Sasang Constitutional Medicine focuses on the different constitutional manifestations of the individual's nature and emotions. The nature and emotions drive the ascending and descending of Qi in the body. And this dynamics of the Qi's ascent and descent shapes the different types of structures, functions and temperaments. Although Sasang Constitutional Medicine has many advantages, its diagnosis of the constitution still depends on the doctors' own idea and has no objective identification. So many doctors in Korea have been trying to solve this problem. Recently, there are several efforts to find out the relationship between genetic information and constitution. By the way, May, 1998 there is a astonishing report about the gene which determines the human performance, that is ACE(angiotensin converting enzyme). And it suggests that the I allele was associated with improved endurance performance. ACE has three genotype including II, ID and DD. "I" means insertion and "D" means deletion. We determined the type of the Sasang constitution with QSCCII questionaire and the one's ACE genotype with PCR of the 127 people and we discovered the relationship between the constitution and the ACE genotype. The result is as follow. Among 39 people who have the II genotype, 7(18%) belong to Taeum(Taiyin), 9(23.1%) belong to Soyang(Shaoyang) and 23(59%) belong to Soeum(Shaoyin). Among 62 people who have the ID genotype, 18(29%) belong to Taeum(Taiyin), 21(33.9%) belong to Soyang(Shaoyang) and 23(37.1%) belong to Soeum(Shaoyin). Among 26 people who have DD genotype, 11(42.3%) belong to Taeum(Taiyin), 4(15.4%) belong to Soyang(Shaoyang) and 11(42.3%) belong to Soeum(Shaoyin). This data indicates that there are implicable relationship between the Sasang constitution and ACE genotype. Especially people who have II genotype have much possibility to be a Soeum(Shaoyin) person (59%) and Soyang(Shaoyang) person have less possibility to have DD genotype (15.4%). With this conclusion, we suggest further study of relationship between the Sasang constitution and ACE genotype and we think that other polymorphism can be a candidate of the partner of Sasang constitution.

  • Landsat 시계열 영상과 실측수온자료를 이용하여 한강 수계 댐호들의 표면수온과 계절적 성층현상을 분석하였다. 1994년에서 2004년까지 29회에 걸쳐 얻어진 Landsat-5, 7 열적외선 영상으로부터 NASA 경험식을 이용하여 호수의 표면수온을 추출하였고, 이를 하천형 댐호인 파로호, 춘천호, 의암호, 청평호, 팔당호의 표층수온, 그리고 호소형 댐호인 소양호의 상층수온(수심 10m) 자료와 비교하였다. 십 수 년간 매월 1회 측정된 수온자료를 위성관측 날짜에 보간하여 사용하였음에도 불구하고, 하천형 댐호들에서는 수온오차(위성관측수온-실측보간수온)의 표준 편차가 $2^{\circ}C$ 이하인 영상이 94개로서, 새로운 통계적 대기보정을 적용할 수 있었다. 실측보간수온과 위성관측수온의 상관계수는 소양호가 0.915 (대기보정 후 0.950), 다른 호수는 0.951-0.980 (대기보정 후 0.979-0.997)로서, 높은 상관성을 보여주었다. 이는 수심이 얕고 인위적인 물의 유입과 유출이 연중 계속되는 하천형 댐호의 표층에는 혼합층이 상시 존재하고 수온의 일변화 및 월변화가 비교적 연속적이기 때문인 것으로 해석되었다. 그러나 소양호에서는 4-7월에 위성관측수온이 실측보간수온보다 $3-5^{\circ}C$ 더 높게 나타나는 이상 수온오차가 관찰되었다. 한강 수계의 최상류에 위치하며 수심이 깊고 자연적인 유입량만이 존재하는 소양호에서 이 시기는 상층수의 물리적 혼합현상이 없이 매우 안정적이고, 일조량 증가에 따라 호수 상층부에 수온약층이 발달하기 때문에, 수심 10m에서 측정된 실측수온보다 위성으로 관측된 표면수온이 연중 비교적 건조한 이 시기에 더 높게 나타나는 것으로 밝혀졌다.

  • Objectives: This study was aimed to find out the characteristics of ordinary symptoms between the control and patient groups, diagnosed as overweight or obesity, in Soyang, Taeeum, and Soeum Constitutions and among those 3 groups. Methods: As a prospective cross-sectional study based on medical records, 9213 patients, who visited Kyung Hee University Medical Center from May in 2007 to June in 2010, were included. To diagnose the constitution, Revised Questionnaire for the Sasang Constitution Classification II and examinations by oriental medical doctors who majored in Sasang Constitution Medicine were performed. Based on the World Health Organization criteria for Asian obesity assessment, body mass index (BMI) was classified into 3 groups; more than 25 as obesity, 23 to 25 as overweight, and less than 23 as normal. Ordinary symptoms questionnaire, which consists of 46 questions in 8 categories, were given to the subjects. One-way ANOVA test in continuous variables and chi-square test in categorical variables were carried out to analyze statistical significance. Results and Conclusions: 1) In general characteristics, we could find out the significant differences in age, sex, height, weight, BMI, waist circumference, blood pressure, total cholesterol, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, fasting blood sugar, and hemoglobin A1c among the 3 Constitutional groups. 2) Soyang Constitution of overweight and obesity has tendency to have higher appetite, like cool or cold water, defecate more, swear more, dislike heat, and have warmer or hotter extremities in the ordinary symptoms, compared with the control group. 3) Taeeum Constitution of overweight and obesity has tendency to have higher appetite, like cool or cold water, defecate more, swear more, dislike heat, and have warmer or hotter extremities in the ordinary symptoms, compared with the control group. 4) Soeum Constitution of overweight and obesity has tendency to have higher appetite and less fatigue in the ordinary symptoms, compared with the control group. 5) Soeum Constitution showed the slightest increase in appetite, preference about room temperature water, less number of feces, and feeling of chill and warmer extremities in ordinary symptoms, compared with Soyang and Taeeum Constitutions. Taeeum Constitution showed the distinct increase in appetite and sweating in ordinary symptoms, compared with Soyang and Soeum Constitutions.

  • 유역의 수자원 수급계획 시 중요하게 사용되는 댐 유입량은 자료의 신뢰성을 확보하는 것이 매우 중요하다. 하지만 단순 물수지법에 의해 산정되는 댐 유입량은 음유입량이 다수 발생하고, 댐 방류량 이외의 유출량을 생략함으로써 실제 유입량 특성을 반영하지 못한다. 본 연구에서는 이러한 문제를 해결하기 위하여, 물수지에서의 유출량 중 고려 가능한 증발량을 고려하여 물수지 개선식을 제시하였다. 소양강댐을 대상으로 재평가된 댐유입량 시계열에서 음유입량의 발생비율이 감소하고, 자료 생산주기별 유입량의 체적은 일관성을 확보하였다. 이외에도 소양강댐 유역에서의 가용수 자원 특성을 검토한 결과, 인간적 측면에서의 직접적인 사용이 약 60%이고, 자연적 측면에서의 간접적 사용이 약 40%인 것으로 나타났다. 또한 가뭄해에는 전체 수자원의 총량 중 간접적인 수자원 이용의 비중이 증가하는 것이 확인되었다.
