This study was attempted to derivate empirical formulas for the runoff: ratio during ilood. season at three watersheds of Dan Yang, Chung Ju, and Yeo Ju are located at upper, middle, and lower portion of Nam Han river basin, respectively. Obtained formulas for flood runoff ratio can be applied as an element for the estimation, peak discharge for the design of various hydraulics structures which can be concidented with meteorological and topographical condition. The obtained through this study were analyzed as follows. 1.It was found that the magnitude of runoff ratio depends on the amount of rainfall for all studying basins. 2.Empirical formulas 'for the runoff' ratio were derivated as 1- 2,707 Rt0.345, 1-1.691 Rt0.242 and 1-1.807 Rt0.227 at Dan Yang, Chung Ju and Yeo Ju watershed, respectively. 3.The magnitude of runoff ratio was appeared in the order of Dan Yang, Chung Ju, and Yeo Ju are located at upper, middle and lower portion of Nam Han rivet basin, respectively. 4.It was assumed that in general the more it rains, the lesser becomes the ratio of loss rainfall. Especially, the ratio of loss rainfall for Dan Yang, upper portion of river basin was shown as the lowest among three watersheds. Besides, the magnitude of that was appeared in the order of Chung Ju and Yeo Ju watershed located at middle, and lower part of river basin, respectively. 5.Relative and standard errors of runoff ratio calculated by empirical formulas were shown to be within ten percent to the observed runoff ratio in all watersheds. 6.It is urgently essential that the effect of antecedent rainfall have an influence on the next coming flood should be studied in near future.

The water conditioning experiments of brown rice were performed to analyze the variation of the milled rice recovery using a continuous type conditioner at Jin-ju, Yeo-ju, and Yong-in RPC(Rice Processing Complex). About 8,000 kgf, 6,000 kgf and 10,000 kgf of the brown rice of 13-14 %(wb) initial moisture contents were used as experimental materials at Jin-ju, Yeo-ju, and Yong-in respectively. The broken rice and rice bran were collected and weighted to calculate the milled rice recovery. The amounts of broken rice with water conditioned occurred lower than that of broken rice without water conditioned. And the milled rice recovery of water conditioned ones were increased as 1.22%, 0.87%, and 1.00% compared with those of the non water conditioned ones at Jin-ju, Yeo-ju. and Yong-in respectively. Especially, the result of the experiments of Jin-ju RPC showed that about 33% and 35% of total increased milled rice recovery were the portion of the moisture content increment and the broken rice reduction respectively.

Background: The purpose of this study was to investigate the comparison between the walking speed and muscle tone of the lower extremity in male and female. Method: The experimental group was that 22 female and 24 male that participated this study. Subjects were measured walking speed and muscle tone. Muscle tone measured using myotonometer. Measured muscle were rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinousus, tibialis anterior, gastrocnemius. Result: The result of this study were that the walking speed were significantly significant(p<.01) in male and female. Muscle tone different in male and female that vastus medialis, vastus lateralis, tibialis anterior and gastrocnemius significantly significant(p<.05). Conclusion: This study showed that difference muscle tone and walking speed in male and female. This indicates that there is an interaction that plays a crucial roles in the walking speed and muscle tone.

Background: The purpose of this study was to investigate the effects of the body alignment on the type and weight of the bag. Methods: The Subjects(n=62) measured posture alignment and make out the questionnaire. The questionnaire item was type of the bag, weight of the bag, side which carries the bag, and time to carry the bag. The posture alignment measured by global posture system(GPS). GPS Measurement was ASIA, acromion process, medial malleolus on Frontal plane, ear, shoulder joint, knee joint, lateral malleolus on sagittal plane, and trunk rotation on transverse plane. Results: The backpack and shoulder bag was no significant. The width of the strap bag was not significant. The side which carries on shoulder bag was statistical significance(p<.05). The time to carry the bag was statistical significance on change of posture(p<.05). A bag weight was no significant. Conclusion: This research provides the direction and carry the bag in time for the posture. This study showed that type and weight of bag does affect body alignment. This indicates that there is an interaction that plays a crucial roles in the type and weight of bag and the body alignment.

Hong and Yeo choose the intention criterion instead of the realization criterion for distinguishing deductive and inductive argument in their paper. This study aims to criticize their argument. I contend that their argument confuses argument reconstruction and argument classification[evaluation], and is making the mistake of utilizing the realization criterion when attempting to make up for the difficulties of the intention criterion. Also, most logicians, including Hong and Yeo, support the division of the argument into deductions, inductions, and bad arguments. Here I insist on a binary division of only deduction and induction. Finally, I argue that there is no need to teach the distinction between deduction and induction when teaching logic.
