To compute the direct runoff basin, The SCS Curve Number can be used simply. It was evaluated by the U.S. soil conservation service and applies to U.S. watershed, In this study to apply the SCS Curve Number to domestic basin, GIS was used to evalute it. In many case, when the direct runoff from the SCS Curve Number is calculated, much unadjusted hydrologic data are demanded. But using and being adjusted of these data are very difficult. In this study, the SCS Curve Number was evaluated through making DataBase by GIS to make simple procedure. and the direct runoff was computed by it. The result of this study shows that Evaluated Curve Number Value is 60.69 in AMC-I, 78.61 in AMC-II and 89.42 im AMC-III Condition from domestic basin

본 연구는 경주지역 1개 고등학교 3학년 여고생을 대상으로 초경 시작 전인 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레 수치와 초경 연령을 파악하여 여성의 초경이 빠를수록 체성장 속도의 변화가 있을 것이라는 가설을 기초로 두 요인간의 관련성을 파악하고자 시행되었다. 경주시 1개 여자고등학교 3학년생 총 317명에 대해 ㅊ경 나이, 초경시 심리 상태, 초경이 시작되었을 때의 상담 여부와 상담하였던 사람, 부모 신장과 초경전후의 식사 규칙성, 다이어트 경험, 수면시간, 스트레스, 음주/흡연 여부, 질병력 등에 대한 설문 조사를 시행하였고, 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레에 대한 정보는 건강기록부에서 확보하였다. 상기 대상자 중 건강기록부가 분실된 39명, 초경나이에 대해 응답하지 않았던 29명 및 결석 등으로 조사를 하지 못하였던 42명을 제외한 조사 대상자는 206명으로 선정하였다. 대상자들의 초경연령 평균값(Mean±SD)은 13.0±1.11이었고, 초등학교 4학년부터 고등학교 2학년까지의 초경 이후 신장 성장률은 감소하였으며, 초경연령이 빠른 군이 초등학교 때는 신장에 있어서 우위를 차지하나 고등학교에 오면서 신장은 비슷한 수준이 되었다. 초경후 1-2년 사이에 체중과 흉위의 증가율은 감소하였고, 초경연령이 빠른 군이 초등학교와 고등학교 사이에 체중과 흉위에서 모두 우위를 차지하였다. 본 연구의 결과는, 흔히 이차 성징의 시작 시점 혹은 사춘기의 시작 시점으로 보고있는 초경 연령이 청소년기의 성장과 밀접한 관련성이 있고, 특히 체중과 흉위의 성장 속도와 밀접한 관련성이 있음을 시사한다. To understand the onset of menarche in relation to changes in physical growth that take place during female adolescence, especially the changes in height and weight velocity. The 207 senior in one women high school of Kyongju were investigated in April 3 to 8, 2001. We collected the information, relation in the age at menarche, height & weight of parents, regularity of eating, and obesity diet, duration of sleeping, sickness & stress near age at menarche, by self-recording. The status of height, weight & chest circumference between the 4th grade of primary school and the junior of high school was collected by individual Health Record. The results were followed; The average age at menarche was 12.95±1.11 years old and the most frequent age of menarche is 13 years. After menarche, the velocity of height, weight and chest circumference were decreased. The most rapid group of menarche hold dominant position in height during elementary school. As time passed, they dont hold dominant position in height. The most rapid group of menarche get an advantage in the weight and the girth of chest after elementary school. The height of subjects is directly proportional to the height of their parents. These results suggest that the starting age at menestuation can be closely associated with physical growth and development.

Transmission of Seasonal Outbreak of Childhood Enteroviral Aseptic Meningitis and Hand-foot-mouth Disease

Park, Sue K.,Park, Boyoung,Ki, Moran,Kim, Ho,Lee, Kwan,Jung, Cheoll,Sohn, Young Mo,Choi, Sung-Min,Kim, Doo-Kwun,Lee, Dong Seok,Ko, Joon Tae,Kim, Moon Kyu,Cheong, Hae-Kwan The Korean Academy of Medical Sciences 2010 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.25 No.5

<P>This study was conducted to evaluate the modes of transmission of aseptic meningitis (AM) and hand-foot-mouth disease (HFMD) using a case-control and a case-crossover design. We recruited 205 childhood AM and 116 HFMD cases and 170 non-enteroviral disease controls from three general hospitals in Gyeongju, Pohang, and Seoul between May and August in both 2002 and 2003. For the case-crossover design, we established the hazard and non-hazard periods as week one and week four before admission, respectively. In the case-control design, drinking water that had not been boiled, not using a water purifier, changes in water quality, and contact with AM patients were significantly associated with the risk of AM (odds ratio [OR]=2.8, 2.9, 4.6, and 10.9, respectively), while drinking water that had not been boiled, having a non-water closet toilet, changes in water quality, and contact with HFMD patients were associated with risk of HFMD (OR=3.3, 2.8, 6.9, and 5.0, respectively). In the case-crossover design, many life-style variables such as contact with AM or HFMD patients, visiting a hospital, changes in water quality, presence of a skin wound, eating out, and going shopping were significantly associated with the risk of AM (OR=18.0, 7.0, 8.0, 2.2, 22.3, and 3.0, respectively) and HFMD (OR=9.0, 37.0, 11.0, 12.0, 37.0, and 5.0, respectively). Our findings suggest that person-to-person contact and contaminated water could be the principal modes of transmission of AM and HFMD.</P>

A Sediment Concentration Distribution Based on a Revised Prandtl's Mixing Theory

Jung, Kwan-Sue Korea Water Resources Association 1997 Korean journal of hydrosciences Vol.8 No.-

Prandtl's mixing length theory was modified to obtain a power velocity distribution in which the coefficient and the exponent are variable over a range from : $$ A simple suspended-sediment concentration distribution was developed from the modified velocity distribytion : $ With nominal values of $\beta$=1.0, $\kappa$=0.4 and visual accumulation tube values of the fall velocity, the comparison between the theory and field measurements by the USGS on the Rio Grande is fair. Doubling the value of the exponent results in a good comparison. Further researches are needed for choosing the values of $\beta$, $\kappa$, and fall velocity values, and consideration on the effects of large-scale turbulence and secondary flows are necessary for them. In a pragmatic sense, on any gaging sites the close analysis of very detailed measurements can establish its specific coefficient and exponent.

Background and objectives: Aseptic meningitis is a disease of children with seasonal outbreak in summer. In spite of high morbidity, it is not notifiable without reported nationwide morbidity. The authors estimated incidence of aseptic meningitis and its descriptive characteristics and time- and space-clustering pattern. Subjects and methods: Cases of aseptic meningitis were extracted from National Health Insurance payment request data of National Health Insurance Corporation from January 1996 to December 2001. Cases were classified by region, institution, and hospitalization. Standardized incidence was calculated and compared by the region, month of the year whether there is any clustering. Results: Nationwide incidence of aseptic meningitis among children under 15 years old over the six year period was 3.48 per 1,000 per year. Incidence was higher in female (2.80/1,000) compared to male (4.02/1,000). Age-specific incidence was highest in 5 years old. Annual incidence was highest in 1997 (8.44/1,000) and lowest in 2000 (0.79/1,000) with outbreak every 3 or 4 years. Outbreak was mostly confined in summer months, between May and September. However, seasonal pattern was variable by year. Southern provinces and metropolitan areas had higher incidences and pattern was more prominent in the years with higher outbreak. Time-dependent pattern of the disease from south to north was not prominent. Discussions and conclusions: We have calculated the nationwide incidence of the aseptic meningitis over six year period. In terms of aseptic meningitis, using National Health Insurance data for the estimation of the incidence is a plausible method for the surveillance of the disease.

Analysis on Failure of Slope and Landslide Dam

Regmi, Ram Krishna,Lee, Gi Ha,Jung, Kwan Sue 한국방재학회 2011 한국방재학회 학술발표대회논문집 Vol.10 No.-

A 3D seepage flow numerical simulation model was developed for seepage analysis of a landslide dam. A 3D seepage flow numerical simulation model coupled with a 2D surface flow and erosion/deposition model was developed for seepage analysis of a slope due to a rainfall event. The conventional water-phase (one-phase) seepage flow model assumes only water phase flow in seepage analysis, which is inadequate for unsaturated soil domains. Hence, a water-air two-phase seepage flow model that considers both water and air phase in the seepage flow process is also used for seepage analysis. Pore water pressure and moisture content data obtained by the seepage flow model were then used to analyze the stability of the slope. Janbu’s simplified method as well as the extended Spencer method was used for the stability analysis. Numerical simulation results and experimental measurements are satisfactorily in agreement.
