A stress anaysis of beams by dividing a beam into small unit beams, analyzing them one by one and combining them into an original beam is knowned as the good methods for an analysis of beams with various states of loads. But these methods are not yet enough in applying for many kinds of loads and many kinds of structures because of the lack of concrete studies. Therefore, in this paper, these methods of beam analysis are proved by analytical methods, and on the basis. of the results, these methods are applied for practical beams with vaious kinds of loads and without difficulties, the disposal of those loads are capable. Especially, you can find these methods of beam analysis are very suitable for the vibration analysis of a high-rise building with many kinds of complicated loads.

The purpose of the study was to see how prevalent the risk behaviors of korean university students using Youth Risk Behavior Surveillance System(YRBSS) developed by the Centers for Disease Control and Prevention(CDC). Translation and modification for Korean students of the YRBS were carried out March 2000 and the modified YRBS were administered to students of 4-year college in Daegu metropolitan city. The number of students used at final analysis was 619(male : 212(freshmen: 101, senior students : 111) female : 407(freshmen : 146, senior students : 261)) Over 50% of university students rarely or never used safety belt and there were no significant difference between freshmen and .senior students. 363 of students had ridden a bicycle during 12 months preceeding the survey. Of these students, almost student(male : 99%, female : 100%) were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 22.8% male freshmen had felt so sad or hopeless almost every day for 22weeks in a row that they stopped doing some usually activities and there were no significant difference between freshmen and senior students. Male student in grades 2. 3 and 4(89%) were significantly more likely than freshmen(42%) to have ever tried cigarette smoking. Almost male students had had >1 drinks of alcohol during their lifetime(lifetime alcohol use) and almost male freshmen(%%) and senior student(%%) had 2 1 drinks of alcohol on 2 1 of the 30 days preceding the survey(current alcohol use). These results suggest that some risk behaviors be very prevalent in a korean university students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during college age, extend into adulthood, are interrelated.

It is well known that obesity is an important cause of risk factor of cardiovascular disease, emphasized by many studies and cardiovascular disease has been found to correlate not only to the extent of obesity, but also the fat distribution of the individual. Recently, focusing on obesity of the abdomen, we were able to evaluate the significance of obesity indices by examining correlations between these indices and the risk factors of cardiovascular disease. Three hundred sixty four health examined persons through out-patient department of family medicine, Seoul hospital of Konkuk medical center were chosen as subjects of this study but finally one hundred twenty five examined persons were selected. The auther analysed correlations between obesity indices and cardiovascular risk factors by measuring serum lipid levels, fasting blood glucose levels and blood pressure that are thought to be risk factors of cardiovascular diseases and obesity indices were calculated using anthropometric measurements. The abdominal obesity indices and risk factors of cardiovascular disease, the levels of total cholesterol in the serum, fasting blood glucose levels, systolic and diastolic blood pressure, increased significantly according to age and there was a significant difference in the abdominal obesity indices according to drinking and smoking habits. Systolic and diastolic pressures had significant differences according to the presence or absence of an alcohol drinking history. There were negative correlatons between HDL-cholesterol and obesity indices(r = -0.248, -0.215, -0.204, -0.256, -0.201) and the weakest correlaton was found or noted between fasting blood glucose level and sagittal diameter. Among obesity indices, sagittal diameter and sagittal diameter per height may be important prognostic indicators or risk factors of cardiovascular disease.

The fcc metal generally have a dual texture, <111> and <100>, after wire extrusion. The relative amounts of <111> and <100> fiber texture depending upon its initial orientation, stacking fault energy and heat treat condition after working. For 2017 Al alloy, increasing the amount of <111> fiber texture with increasing the strength. But the <111> fiber texture decrease with solution treatment after working, leading to the weak randomized sample.

Under the various clinical circumstances, there is a condition to change source to skin distance(SSD). It is possible to correct photon beam by well-known inverse square law. On the other hand, the electron beam is not exact location of source, that's why it is difficult to apply as it is. In case of electron beam, we should correct the difference of SSD by measure effective SSD . There are many ways to measure effective SSD. In this study, Faiz Khan's method was used. The measurement energy is 6,9,12,16,20 MeV and field size is set standard applicator 6×6, 10×10, 15×15, 20×20, 25x25㎠. From the bottom of the standard applicator to skin distance is set to 5㎝. So we measured dose at the gap to 0∼20㎝. According to a production company of linear accelerator, or even though same production company, the qualities of electron beam can be different. So, effective SSD can be different every several accelerator. Therefore, it is desirable to use the effective SSD measured at every electron beam energy and field size actually.

1999년부터 2001년까지 3년간 친환경농업 시범마을에 적용되고 있는 INM (Integrated Nutrient Management) and IPM (Integrated Pest Management) 실천에 따른 추진효과를 분석하기 위하여 시범마을로 지정된 옥천과 양평지역의 농가 포장에서 시비량, 양분유실 및 생태계 변화 등을 조사 분석하였다. 3요소 시비량은 토양검정시비로 인하여 농가관행시비와 비교하여 28.6~39.4% 절감할 수 있었으며, 쌀 수량도 시비량이 비교적 적은 토양검정 시비구에서 3~10% 증수하였다. 영농기간동안 토양 침투수중 NO₃-N 농도는 농가관행 시비구 2.9 ㎎/L에 비하여 토양검정 시비구는 1.5 ㎎/L로 감소하였으며, 시범마을 논으로 유입되는 관개수의 COD, NH₄-N, NO₃-N 농도는 각각 15.0, 0.67, 1.39 ㎎/L, 시범마을 논에서 배출된 용수는 각각 12.4, 0.29, 2.42 ㎎g/L로 감소되는 경향이었다. 처리별 수서곤충, 환형동물, 패류 및 감각류 등의 개체수는 농가관행구 100에 대하여 토양검정 시비구 293, 토양검정과 개량제 혼용구 276, 무비구 90으로 토양검정 시비구에서 많았으며 수서 무척추 동물은 관행농업을 수행하고 있는 지역을 100으로 볼 때 친환경농업마을은 242와 443으로 INM과 IPM을 실천하는 시범마을에서 생물종이 다양하고 그 개체수가 많은 것으로 나타났다. 친환경농업 시범마을 조성 후 작물 추천시비량 준수와 적기 예찰을 통하여 필요이상 사용되는 비료와 농약을 절감하여 생태계의 개선과 토양이 건전화된 것으로 평가되었다. In order to preserve the soundness of ago-ecosystem and products safety in agriculture, this study was evaluated environmental impact in relation to the INM (Integrated Nutrient Management) and IPM (Integrated Pest Management) at paddy fields at Ok-Chun and Yang-Pyung region. By introduction of INM with the application of BB(bulk-blanded) fertilizer based on soil analysis and EM, the application rate of fertilizer was reduced to about 28.6-39.4% and the yield of brown rice was increased to about 3-10% compared to conventional practices. The concentrations of COD, NH4-N, and NO3-N in irrigation water flowed to the environmental-friendly agriculture practices were 15.0, 0.67, and 1.39 ㎎/L, respectively. The concentrations of COD, NH₄-N, and NO₃-N from paddy fields in drainage water were 12.4, 0.29, and 2.42 ㎎/L, respectively. The total number of the freshwater invertebrates was higher in field treated with fektilhtion by prescription with soil testing. Also, the population density of aquatic insects was higher than the other fields at both demonstration villages. In conclusion, it was possible to reduce the amount of fertilizer and agricultural chemicals application, and increase the yield of rice by application of the environmental-friendly agriculture practices.
