This is one of the preliminary researches for preventing osteoporosis in women of before and after menopause. We examined 63 women of 46-60 age(1-3 grade students' mothers of P highschool in Pusan) in order to check the standard of primary factors and prevention about osteoporosis by analyzing the questionary which was written by them. As a result, we got the relationship among RF(Risk Factor), PF(Prevention Factor), Age and BMI of osteoporosis is as follows : 1. The relationship between PF and RF was-0..315 and R^2=0.100 at the properness exam of the model. 2. The relationship between BMI and RF was low as 0.076 and R^2=0.006 at the properness exam of the model. 3. The relationship between Age and RF was 0.226 and R^2=0.051 at the properness exam of the model. 4. The relationship between BMI and PF was low as 0.015 and the result of the properness exam of the model got no meaning as 0.000. 5. The relationship between Age and PF was -0.13 and R^2=0.017 at the properness exam of the model. 6. The relationship between Age and BMI was 0.233 and R^2=0.054 at the properness exam of the model. The above facts are presumed as the result of the questionary which has sample size and low distinction. So if these problems are improved in the next study, more meaningful result can be obtained.

The purpose of this study was to compare the dye leakage of MTA (mineral trioxide aggregate) apical plug produced by two orthograde placement techniques (hand condensation technique and ultrasonically assisted hand condensation technique). To simulate straight canal, 60 transparent acrylic blocks with straight canal were fabricated. These transparent acrylic blocks were divided into 2 groups (Group C: hand condensation technique (HC) and Group U; ultrasonically assisted hand condensation technique(UAHC)) of 30 blocks with each MTA application method. Each group was divided into 2 subgroups (n = 15) with different canal size of #70 (subgroup C70 and subgroup U70) and #120 (subgroup C120 and subgroup U120). After apical plug was created, a wet paper point was placed over the MTA plug and specimen was kept in a humid condition at room temperature to allow MTA to set. After 24 hours, remaining canal space was backfilled using ObturaⅡ. All specimens were transferred to floral form socked by 0.2% rhodamine B solution and stored in 100% humidity at room temperature. After 48 hours, resin block specimens were washed and scanned using a scanner. The maximum length of microleakage was measured from the scanned images of four surfaces of each resin block using Photoshop 6.0. Statistical analysis was performed with Mann-Whitney U test. Group U of UAHC had significantly lower leakage than Group C of HC in #70-size canal (subgroup U70) (p<0.05). 이 연구의 목적은 서로 다른 두 개의 근관 크기(#70, #120)를 가진 레진 모형에 MTA (mineral trioxide aggregate)를 서로 다른 두 가지 방법 (수기구 충전(HC), 초음파 보조 수기구 충전(UAHC))으로 정방위 충전하고 MTA apical plug의 미세누출을 평가하는 것이다. 직선형 근관 형태를 가지며, #70과 #120의 치근단 크기를 갖는 레진 모형을 각각 30개씩 준비하였다. 이 시편들을 MTA의 적용 방법에 따라 각 군을 2개의 아군으로 다음과 같이 분류하였다 (n=15); C70: HC + 치근단 크기 #70, C120: HC + 치근단 크기 #120, U70: UAHC + 치근단 크기 #70, U120: UAHC + 치근단크기 #120. MTA충전을 완료한 후에, 24시간 동안 실온에서 100% 습도를 유지하여 경화시켰다. 근관의 상부는 열연화 충전 시스템(Obtura Ⅱ)을 이용하여 충전하였다. 48시간 동안 100% 습도를 유지하여 실온에서 0.2% rhodamine B 용액을 이용해 미세누출 실험을 하였다. 이 연구결과 #70의 치근단 크기를 갖는 그룹 사이에서 UAHC가 HC에 비해 미세누출이 적은 것으로 나타났다(p<0.05). 이 연구 조건하에서는 초음파 진동을 동반한 정방위 MTA apical plug 형성 방법이, 특히 좁은 근관에서 더 효율적 인 것으로 사료된다.

This study is to elucidate how dance effects on the increase of bone density when girls are growing up. The subjects are two groups. One is the group majoring dance(Korean traditional dance, ballet), the other is comparative group in girls' high school. The bone density of lumber(L1~L4) and Femoral neck, Ward's triangle, Trochanter of the femoral region are measured using DEXA. As a result, It can be concluded as follows: 1. The groups(Korean traditional dance group and ballet group) showed more significant increase than comparative group in the neck bone density.(p< .05) 2. The Ward's bone density of majoring dance groups is higher than comparative group in the order of Korean traditional dance group(10.88%), ballet(7.72%), but it doesn't appear significant difference. 3. The Troch region bone density of Korean traditional dance group is significantly as high as the level of p<.05, however ballet is 5.9% and is not significantly different from comparative group. The above consequence shows us that a regular dance activity could be thought to increase effectively the bone density of the growing high school girls in lumber and the femoral region.

This study intended, through some basic healths test, to find out the body composition, the blood components, and the immune function of the obese high-school girls. With 2 groups of 16 subjects, the eight obese group and the other eight non-obese group, the results are following: 1. In the body composition analysis, its quantity comparison indicates that the obese group shows significance higher than the non-obese group in Body fat and Weight (p<.001). The rate of comparison per weight of body composition tells that the former shows significance lower than the latter in every item(% Water, % Protein, % Muscle, % LBM) except the item % Mineral. (p<.001) 2. In the biochemical serum test, there is much higher significance of the obese group than the non-obese group in TC and TG (p<01), but there is not any significance difference in HDL-C. 3. In the blood test, the significance difference of the obese group is much higher in RBC, Hct, PLT(p<.01) and Hb(p<.05), but not in WBC. 4. In the leucocyte test(WBC diff) to find out their immune function, the obese group shows lower significance difference than the non-obese group only in Monocyte and Eosinophil.(p<.05), but not in Neutrophil, Lympocyte and Bosophil. From the above results, the obese high-school girls seem to have a good nutrient status and show no abnormality in their body composition and blood elements. But the result of WBC diff cannot show clearly the difference between two groups, which tells the need of the further investigation on T-cells and B-cells in lymphocyte.

본 연구에는 CIS를 이용하여 장기유출 해석 모형의 하나인 NWS-PC모형의 매개변수를 얼마나 적절히 추정할 수 있는가에 대해 알아보았다. 수치표고모형, 수치토양도 및 인공위성영상을 분석하여 얻은 토지이용도 등을 기본 자료로 이용하였고 소유역별 특성값을 GIS를 이용하여 추출하였다. 이러한 특성치들은 Amstrong(1978)에 의거하여 소유역별 모형의 매개변수를 추정하는데 직접이용된다. NWS-PC 모형의 경우 추정된 매개변수는 가능한 값의 범위로 주 This study is to see how effectively the NWS-PC model parameters can be estimated using GIS. Basic informations such as DEM(Digital Elevation Model) ,digital soil map, land use information from satellite image are provided and analyzed for estimating the sub-basin characteristics in GIS. These charcateristics are used to estimate the model parameters for each sub-basin. The model parameters estimated based on Amstrong(1978) are given as a possible range, which will be fixed through the calibration procedure. In this study, we used the1974 data for calibration and the 1979 event for verification. From the calibration procedure, we could find that the parameters related with infiltration and water tend to have the minimum value of the range and that the parameters related with exfiltration of water tend to have the maximum value of the range This result seem to reflect the hydrologic characteristics of Keum-river basin, which could be used to fix the model parameter without difficult calibration procedure. The simulation results show that the relative error of calculated discharge to observed discharge to be within approximately 10% . Therefore, the model with the parameters calibrated was considered to be adaptable for long-term runoff analysisf or Keum-river basin.

The results about the influence of exercise on BMD were different from each literatures; some showed the influence was restrictive, others whole. But many studies have suggested that a physical exercise can be a very important factor to cure and prevent osteoporosis because exercises have a close relationship with BMD. Like this, through the literature study, the results about the influence of exercise on BMD are as follows; 1.The proper exercise with the intake of calcium is effective in cure and prevention of osteoporosis. 2.A steady and dynamic weight bearing exercise is the proper pattern of exercise. 3.The bone loss at menopause is mainly affected by hormone but the loss can be reduced according to the degree and strength of exercise. 4.A steady training can increase BMD in a growth period and prevent osteoporosis in an old age because it prevents bone loss.

It is necessary that the civil servants have high level of ethical norms and management science technique. Until now the mainstreams in the field of public administration have been administrative responsibility and ethics, 'cause corruptions of the public servants have been taking place all the time. Therefore, due to the peculiar characteristic of the government action principles reguired for the civil servants are much more strict then those for the members of other organizations. Particularly in the administrative state, civil servants are said to the provider and the change agent for the nation requiring more ethical consciousness. Judging from the 「charters of civil servants ethical」 and 「law on national civil servants」, ethics and responsibility reguired for the public servants in of almost importance. There wouldn't be my problems if observed. However the reality in not so simple, Thus ethical consciousness and the proper actions of public servants are urgently needed. Several virtures are prerequiste for the execution of ethics and responsibilities of the servants. In this paper, such essential virtures are reviewed. I'll look into how public servants are indulged into corruption depending upon the environment and circumstance. In addition, examples from foreign countries will also be investigated in that we can learn valuable lessons from them, Finally, the establishment of ethical actions which are not prone to corruption are pursued. One way of establishing ethical adions is ‘feeling of balance’, ‘principle of discipline’, and ‘categorical imperative’.

Catalytic oxidation of methane was studied in a fixed bed flow reactor. Supported Pd and La promoted Pd catalysts were prepared by incipient wetness impregnation method. Up to 0.5wt.% of Pd, the catalytic activity was increased with Pd loading. However, the activity did not change above that loading. 0.1wt.% La added Pd catalysts showed increased catalytic activities due to increased methane and oxygen adsorption. La addition proved to increase the dispersion, thus increases thermal stability of the catalysts. However, when the loading of La exceeds 1.0wt.%. methane oxidation activity was decreased. presumably due to the pore and Pd blocking by added La.
