To investigate the SaO_2 changes according to positional change in general anesthetic patients, 80 ASA physical state class I-II patients were studied. Each group classified supine position group, group to change from supine position into sitting position, group to change from supine position into prone position and group to change supine position into lateral position. After intubation, in the supine position SaO₂was checked and then positional changes performed. After that we checked Sa0_2 in 1, 5, 10, 15, 30, 60 minutes respectively. The results were as follows. 1) In supine position, time-dependent SaO_2 change was not significant statistically(p>0.05). 2) In the change into sitting position, time-dependent SaO_2 change was not significant statistically(p>0.05). 3) In the change into prone position, time-dependent SaO_2 change was not significant statistically(p>0.05). 4) In lateral positional change, time-dependent SaO_2 change was not significant statistically(p>0. 05). 5) Among the groups there were no significant SaO_2 changes according to positional change compared with supine position statistically. In conclusion, this experiments revealed that the change in SaO_2 according to positional change was not significant.

City`s Ecological Landscape in the Digital Age Lee Kyung-Lae, Park Kyou-Hyun, Cho Yeon-Jung We all know how beautiful our wild and it`s importance to our living planet Earth. But did you realise the speed at which man himself is damaging it`s unique natural habitat. We are well on our way to destroy our forests, plants, wetlands. We are polluting our oceans and seas. This way, we`re driving numerous animal species, plant species and many others into extinction. Everyone should be aware of the importance of our natural environment. We live in the period of echocide. Why we need nature to survive and how we can deal with the environmental problems we face. This paper has the purpose to reform city`s environment. Because, Metropolis and megalopolis are the principal cause of environmental disruption. To reform the city is needed to consider digital technology in our age. In the face of economic and cultural globalization, many have argued that we live an increasingly placeless world. However, as a growing number of cities participate and compete in key marketplaces of advanced capitalism, the spectacle of the city is more than ever a significant medium of communication in its own right. In doing so, this work is focused specifically on the dimension of city`s media environment. To that end, the paper examined U-City and U-Eco city. In this study, we will introduce the study on model of U-Eco City as one way for the eco-freindly future city.

In order to verify differences in analytic results of mercury concentration in food due to analytical methods, both dithizone and gold amalgam methods were applied to estimate mercury concentrations in soybeans and in soybean-sprouts cultivated in our laboratory. Recovery rates of mercury by standard additions method were similar for both analytical methods with values ranging from 85 to 105%. Loss or contamination of specimens with mercury during the wet digestion process was found to be negligible. The result of the analysis revealed that the mercury concentrations measured by the dithizone method estimated to be 10-20 times as high as those measured by the gold amalgam method. The causes of this difference in analytic results between the two methods appeared to be due to undetected volatilization of mercury from the specimen during descication process in the gold amalgam method, but exact nature still remained unclarified. It was confirmed that the mercury concentrations in soybean sprouts decreased in the process of cooking and boiling (p<0.01), but those in soybeans did not (p>0.1).

This study was conducted to determine the optimum shape and dimension of plate predicting the sink age of power tiller in soft paddy field. Various size of disc and rectangular plates were tried at five different soil moisture content, and the resules are summarized as follows. 1. Linear relationship is recognized between contact pressure and sinkage of plates using log-log paper at higher soil moisture content, but the plate sinkage is affected by hard pan in case of the lower moisture soil conditions. 2. Concerning the value of soil deformation coefficient K, the variation of measured values due to shape and size of plate can be practically negligible for the rectangular plates which have 2.5, 5 and 10cm width and with 2 or 3 aspect ratio, and the disc plate which has 20cm diameter. The variation of the exponent of sinkage n, can be practically negligible for the rectangular plates which have 5, 10 and 15cm width, and disc plates which have 20 and 30cm diameters. 3. Relationship between the sinkage of some type of plate and that of power tiller was linear. The closest relationship were found between the sinkage of power tiller and plates for 2.5 and 5cm width rectangular plates regardless of aspect ratio and for the disc plates having 10 and 20cm diameters. 4. Consequently, the optimum plate shape and size for predicting the sinkage of power tiller in soft paddy field are found as the rectangular plates which have 5 and 10cm width and 2 or 3 aspect ratio, and the disc plates having 10 and 20cm diameter.

For a purpose of searching a rational means of estimating an amount of mercury absorption in normal metabolic process, and to obtain data concerning normal concentrations of mercury in blood, urine and hair of the male adults living in Seoul, Korea, 58 male volunteers aged from 20 to 30 years of age who had no obvious exposure to mercury for occupational and/or therapeutic purposes were selected, and mercury concentrations in blood, urine and hair specimens collected from them were analyzed by dithizone calorimetric method. 1. Frequency distribution of mercury concentrations in urine and hair specimens were well fitted to the log-normal distribution with the equivalent sample means and standard deviations, and that of mercury in blood was fitted to both the normal and the log-normal distributions. 2. Mean mercury concentration in the 24-hour urine specimens was ln^-1 2.48 ㎍/ℓ±ln^-1 0.67㎍/ℓ (x￣_g±s_g=11.95㎍/ℓ;X_max-X_min=23.3㎍/ℓ∼6.12㎍/ℓ). 3. Frequency distribution of mercury concentrations in the 24-hour urine specimens was better fitted to the log-normal distribution when the value was adjusted by specific gravity of urine 1.024 or per gram of creatinine excretion per liter of urine. Mean value of mercury excretion in the 24-hour urine specimens was ln^-1 2.88㎍/ℓ×((0.024/S.G.-1.000)±ln^-1 0.60㎍/ℓ) × ((0.024/S.G.-1.000)(x￣_g±s_g=1. 81㎍/ℓ))×((0.024/S.G.-1.000)±1.65㎍/ℓ)×(0.024/S.G.-1.000);X_max∼X_min=(29.9㎍/ℓ×(0.024/S.G.-1.000)-11.0㎍/ℓ×(0.024/S.G.-1.000)), and ln^-1 2.89㎍/g · creatinine/ℓ±ln^-1 0.62㎍/g·creatinine/ℓ (x￣_g±s_g=18.0㎍/g)·creatinine/ℓ±1.86㎍/g · creatinine/ℓ;X_max∼X_min=33.5㎍/g·creatinine/ℓ∼9.7㎍/g·creatinine/ℓ),respectively. 4. Frequency distribution of mercury concentrations in hourly-voided urine specimens was fitted to the log-normal distribution as well, showing the mean of ln^-1 3.07㎍/g·creatinine/ℓ±ln^-1 0.77㎍/g·creatinine/ℓ(x￣_g±s_g=21.5㎍/g·creatinine/ℓ±2.16㎍/g·creatinine/ℓ);X_max∼X_min=46.4㎍/g·creatinine/ℓ∼10.0㎍/g·creatinine/ℓ) with greater dispersion of mercury excretion than in the 24-hour urine specimens. 5. Mercury excretion in the hourly-voided urine specimens showed a diurnal varition (p<0.01), as minimal as ln^-1 2.72㎍/g·creatinine/ℓ±ln^-1 0.76㎍/g·creatinine/ℓ(x￣_g±s_g=15.2㎍/g·creatinine/ℓ±2.14㎍/g·creatinine/ℓ);X_max∼X_min=32.5㎍/g·creatinine/ℓ±7.10㎍/g·creatinine/ℓ) in urinevoided at 6 o'clock in the morning and as maximal as ln^-1 3.34㎍/g·creatinine/ℓ+ln^-1 0.58㎍/g·creatinine/ℓ (x￣_g±s_g=26.6㎍/g·creatinine/ℓ±2.10㎍/g·creatinine/ℓ);X_max∼X_min=55.9㎍/g·creatinine/ℓ∼12.7㎍/g·creatinine/ℓ) in urine viided at 1 o'clock in the afternoon. 6. Frequency distribution of mercury concentrations in blood was fitted to both the normal and the log-normal distributions with the arithmetic mean of x￣±s=30.2㎍/100ml±14.96㎍/100ml and the geometric mean of ln^-1 3.23㎍/100ml±ln^-1 0.57㎍/100ml(x￣_g±s_g=25.3㎍/100ml±1.77㎍/100ml;X_max∼X_min=44.8㎍/100ml∼14.29㎍/100ml). 7. Frequency distribution of mercury concentrations in hair was log-normally distributed with the mean of ln^-1 0.45㎍/㎍/g±ln^-1 0.56㎍/g(x￣_g±s_g=1.57㎍/g;X_max∼X_min=2.75㎍/g∼0.90㎍/g) 8. Frequency distribution of mercury concentrations in urine, when expressed in terms of ㎍ per liter, was well fitted to the logarithmic, exponential and power curves with that in hair (㎍/g). No relationship, however, was found between mercury in urine and in blood (㎍/100ml), and between mercury in blood and in hair.

Japanese imperialism was switchovered after independent movement in 1919 the military rule to the cultural politics. But still they took the basic policies to make the Japanized Koreans. These are important educational policies during this period (1922∼1938). 1. Educational system was changed like the Japanese. So it seemed that there were no differences between Korean and Japanese. 2. They established the normal school (a secondary school) for teachers' training of the elementary school. but not a teachers' college. 3. They established only college the law and literature and the medical department, and moreover they limited the entrance opportunity to the Korean students by the co-education system with Japanese. 4. They emphasized the education of technic and labor to produce the lower worker. 5. They strengthened the education to make the Koreans by using the Japanese teachers and increasing the Japanese classes.
