Acute Blood Compositions change were determined in 18 Healthy college aged-men completing three counterbalanced running trial at different exercise intensities: trial 1 at 50%LT, trial 2 at 100% LT intensity and 150%LT intensity. For each trial, blood samples were collected at pre-exercise(baseline), immediately post-exercise(PE), 24 hours(24h) and 48 hours post-exercise. Serum samples were analyzed for Hematocrit(Hct), Red Blood Cell(RBC), White Blood cell(WBC), Hemoglobin(Hb), and plasma Volume Change(PVC). In addition, capillary blood samples were collected for analysis of blood lactate concentrations during incremental test to determine LT. All samples were compared to pre-exercise(baseline). In assessing the blood compositions change variables, significant difference was determined in chages of Hct, RBC, Hb at various intensities over time. However, there was no significant difference in WBC, PVC at any intensity. Consequently, there was significant difference between the 150%LT and the 50%LT for the blood compositions change. I thought that the 50%LT and the 100%LT which was used the exercise protocol with 400 calories consumption didn't support the stimulation enough to response during the exercise even though 150%LT stimulated subjects to get less response than previous studies.

The purpose of this study is to examine the effect of warming up in swimming on Lactate Density which makes man be exhausted. And this study is to analyze the effect of cooling down in removing Lactate and the relation with heartrate. The test was practiced in the swimming pool of H University and 14 university students, who has two years experience in swimming and are healthy, were selected for this study. Seven students were warming up and cooling down group and seven were other group. Warming up and cooling down was done 15minutes. This exercise was done 5minutes swimming and 1minutes rest during twenty minutes. The measurement of Lactate and heartrate was conducted stable period, right after warming period and exercise period of body per 5minutes (3times). Just after exercise, cooling down and restoration period per 5minutes (3times), the measurement was conducted. And after cooling down(after 35minutes), the measurement was practiced. The average and standard deviation were conducted on each analysis part. The average difference between groups was analyzed by Two-way ANOVA. The difference in group was examined by Bonferroni test at the p<.05 level of significant. The results as follows 1. Warming up 1). Just after warming up, each group's lactate amount in blood has significant change (P<.05). 2). Just after warming up, lOminutes exercise, 15minutes exercise and 20minutes, each group's heartrate has significant change.(p<.001, p<.01, p<.05, p<.01) 3). All groups have significant change on the lactate and heartrate through exercise (p<.05, p<.01, p<.001). 2. Cooling down 1). After cooling down, each group's lactate amount in blood has no significant change. 2). Each group's heartrate has significant change just after cooling down after 5minutes and 10 minutes(p<.01, p<.05). 3). All groups have significant change on the lactate and heartrate through restoration period(p<.05, p<.01, p<.001).

核分裂 및 放射化生成物質에서 放出하는 여러가지 감마선들은 核燃料를 破壞하지 않고도 推出할 수 있는 많은 情報를 包含한다. 그러나 半導體 檢出器에서 얻은 복잡한 스펙트럼에서 이러한 정보를 推出하기가 容易하지 않기 때문에 電算코드의 使用이 必要하게 된다. 本 硏究에서는 그동안 國際的으로 널리 普及되어 使用되는 감마선 分析 프로그램들의 長點을 취하여, 감마선은 물론 X-線의 스펙트럼도 피팅(fitting)하여 피이크의 중심과 면적을 正確히 計算할 수 있는 전산코드 CAERI를 開發하였다. CAERI는 FORTRAN으로 쓰여있고, 특히 固有輻射線幅(natural line width)을 무시할 수 없는 X-線의 피이크 表現函數인 Voigt 函數에 대해서는 다른 X-線 分析 프로그램들이 使用한 간단한 近似式 대신에, 더욱 正確한 無限級數近似式을 사용하였다. 특히 CAERI는 U이나 Pu과 같은 重元素의 核種分析時에 直面하는 감마선과 U이나 Pu의 X-線이 任意로 ()()하여 共存하는 복잡한 스펙트럼까지도 取扱할 수 있다. ()Lu감마선과 ()U K()X-線의 試驗스펙트럼을 피팅하여 다른 프로그램들의 피팅결과와 비교했을 때 좋은 一致를 보았다. A great variety of nuclear gamma rays emitted from fission and activation products of spent nuclear fuel contains much information that can be clicited without affecting the integrity of the fuel elements. But the extraction of such information form the comples spectrum is difficult and requires computer codes. In the present work, a versatile code "CAERI" was developed which located peaks and calculates their areas for X-rays as well as gamma rays using elegant features of some widely used program for gamma-ray peak fitting. "CAERI"coded in FORTRAN used infinite series approximation more accurate than other workers various simple, piecewise series approsimations for evaluations of the Viogt function which represents the X-ray peak with non-negligible natural line width. "CAERI" can handle even a complex multiplet consisting of peaks from X-rays and gamma rays in arbitray mixture, which one often encounters in the isotopic analysis of heavy elements such as U and Pu. The results of the fitting performed on the test spectra of ()Lu ()-ray and ()U K() X-ray show good agreement with those by previous workers.

Micro gas-flow sensor is fabricated using a microfabrication technology and micromachining techniques. An NON insulated film with low thermal conductivity and low internal stress is deposited by using LPCVD and APCVD process. As the micromachining technology, characteristics of silicon wet anisotropic etching are investigated. Experimental variations for (100) etch rate observation are following ; (1) TMAH concentrations in water (3∼25wt.%), (2) etch temperatures (80∼90℃). The etch rates for (100) silicon increases with increasing etch temperature and with decreasing TMAH wt.% concentration. Platinum thin films are deposited on the NON film by rf sputtering and lift-off method. Micro gas-flow sensor combined with platinum film heater and temperature detector is fabricated. And its operational characteristics are measured in the range of 0∼500sccm of nitrogen gas flow-rate. The gas-flow sensor have been shown a good linear relationship between the oxygen content in helium and the resistance of temperature detector within 0 to 18mol% of the oxygen contents. with the constant total flow-rate of 225sccm.

Silicon micromachining technology can be used to build microsensors and actuators by using tools derived from standard IC processing. For the silicon micromachining the etching characteristics of tetramethyl ammonium hydroxide (TMAH) by dissolving silicon powder or silicic acid have been studied. The 3. 5 and l0wt.% TMAH solutions, with dissolved silicon powder (6g/l) or with dissolved silicic acid(Si(OH)_(4), 16g/1) were used. And ammonium peroxydisulfate (APODS. 2g/l) dissolved in the solutions were also used. The etch rates of silicon and the etched surface roughness were observed with various etching conditions. The crystallographical aspect on the crystal orientation of silicon have been studied. With sufficiently fresh solutions, these TMAH concentration and combination of etchants. provide repeatable etch properties. does not attack exposed aluminum or silicon dioxode. and provide smooth (100) silicon surfaces.
