The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.

The CTSIB (Clinical Test of Sensory Integration on Balance) using high sensitive pressure sensors is normally used to assess the sense of balance in hospital. It takes an objective measurement of the amount of sway that occurs in the body trunk by observing the change in the center of pressure (CoP) on the foot at the upright posture. In this paper, we would like to propose method to easily measure trunk sway in home. Although the Wii balance board(WBB) is used for games, it can measures the center of pressure, which is highly correlated. The Wii remote controller(WRC) is inexpensive compared to the WBB, but it has problems with estimation of trunk sway because it can't measure pressure directly like WBB. We collected data from 10 normal subjects (5 males, 5 females) from two devices in order to compare the CoP from WBB and the center of mass (CoM) from WRC. The results of WRC and WBB was similar when the data were analyzed by the convex hull and ellipse area.

Most of the currently available rice threshers in Korea are of head-feeding type originally developed for threshing paddy at grain moisture content of 15 to 17% on wet basis. And prevailing rice harvesting system is swathing or cutting and bundling upright rice crop at a maturity stage of grain moisture content of ca. 28 to 20%, followed by transient natural drying in the field and threshing at grain moisture content of about 17%. The system often allows rather high field loss of rice both quantitatively and qualitatively. These necessitate use of a preharvest desiccant, and diquat has been registered recently as a rice desiccant. Aim of the present study is to determine the best time and rate of diquat application and to evaluate its utility as a rice desiccant under its optimal usage conditions in Korea. Diquat was not so effective for japonica rice varieties while it was very effective for the new varieties bred from indica x japonica crosses. The best time of application was the period from 2 days before to 3 days after physiological maturity of grain (moisture content of 28% w.b.) and the optimal rate was about 330g of diquat ion/ha. Applying diquat at the right time and rate dropped grain moisture to 15 to 16% (w.b.) within a week after treatment in contrast to that of 20 to 24% in untreated rice. Desiccation of rice crop with diquat resulted in 10 to 15% increase in grain resistance to shattering and significant reduction in percent green rice. However, there was no reduction in milled rice yield and percent whole kernel and was no change in the percent chalky rice and percent tinted rice. Diquat use appears highly desirable, if there is no residue problem which has not been studied in the present study.

'Mansoo' is a late-season pear cultivar with extra large and high quality fruit of long storability, which was released by National Horticultural Research Institute in 1995. The cultivar originated from the cross between 'Danbae' and 'Okusankichi' at Suwon in 1978, had been under regional adaptability test at nine areas in the name of 'Wonkyo Na-15' for 4 years since 1992. It was vigorous in tree growth and upright in tree shape. Its flower bud is easily maintained, resulting in higher productivity than 'Danbae' and 'Okusankichi'. It bloomed a day later than 'Niitaka', and showed cross-compatibility with 'Niitaka', 'Chojuro' and some other varieties. Harvesting time of 'Mansoo' is late October in Suwon. The fruit shape is oblate and skin color is light yellowish brown. The fruit weighed 600-700 g and has 12-13% soluble solids content. The flesh is soft, juicy, and has negligible grit. It is resistant to black leaf rot (Alternaria kikuchiana Tanaka).

Otter boards in the trawl are the one of essential equipments for the net mouth to be spread to the horizontal direction. Its performance should be considered in the light of the spreading force to the drag and the stability of towing in the water. Up to the present, studies of the otter boards have focused mainly on the drag and lift force, but not on the stability of otter boards movement in 3 dimensional space. In this study, the otter board is regarded as a rigid body, which has six degrees of freedom motion in three dimensional coordinate system. The forces acting on the otter boards are the underwater weight, the resistance of drag and spread forces and the tension on the warps and otter pendants. The equations of forces were derived and substituted into the governing equations of 6 degrees of freedom motion, then the second order of differential equations to the otter boards were established. For the stable numerical integration of this system, Backward Euler one of implicit methods was used. From the results of the numerical calculation, graphic simulation was carried out. The simulations were conducted for 3 types of otter boards having same area with different aspect ratio(${\lambda}=0.5,\;1.0,\;1.5$). The tested gear was mid-water trawl and the towing speed was 4k't. The length of warp was 350m and all conditions were same to each otter board. The results of this study are like this; First, the otter boards of ${\lambda}=1.0$ showed the longest spread distance, and the ${\lambda}=0.5$ showed the shorted spread distance. Second, the otter boards of ${\lambda}=1.0$ and 1.5 showed the upright at the towing speed of 4k't, but the one of ${\lambda}=0.5$ heeled outside. Third, the yawing angles of three otter boards were similar after 100 seconds with the small oscillation. Fourth, it was revealed that the net height and width are affected by the characteristics of otter boards such as the lift coefficient.

"The four types of temperament" (hereinafter "Sa-Sang Constitutional Medicine") is applied to not only medicine, but also various fields like management, politics, education, etc. Despite that "Sa-Sang Constitutional Medicine" is "Mind-Body Medicine" which is fundamentally based on "Controling Mind and Body", though, it was rarely used for psychotherapy in practical. Practical treatment on clinical medicine is limited to only medicine-treatment or acupuncture-therapy. However treatment on illness and pathological phenomenon suggested by "Sa-Sang Constitutional Medicine" keeps individual's nature in control, and it governs environmental facts: age, region, and socio-cultural factors: alcohol, debauchery, riches, authority(酒 色 財 權). Especially, "Moral Cultivation" in "Sa-Sang Constitutional Medicine" emphasizes the importance of properly understanding vice(邪心) and laziness(怠行) concealed in natural temperament of human being, and pursuing "Understanding Each Other(博通)" and "Upright Conduct by Oneself(獨行)". Furthermore, because "Sa-Sang Constitutional Medicine" is developing medical theory based on "Understanding Others(知人)" and "Straighten Oneself(正己)" doing try integral approach, it has great implications for the present generation that forms much of social connection. Similarly, Ken Wilber who is one of representatives of "World Philosophy" and "Integral Psychology" is suggesting "Integral Life Practice" (hereinafter ILP) - applies practical and heuristic "Integral Approach" to individual experiences. ILP is the only practical discipline for development of viable whole-area. ILP says that there are four core modules: body, mind, shadow, spirit(靈), and five auxiliary modules: morals(倫理), gender(性), work(일), emotion(情緖), relationships(關係性). These nine modules could apply mind-body treatment of "Sa-Sang Constitutional Medicine", and thereby more developed mind-body treatment would be found.
