  • 1. Objectives The purpose of this study is to find the kinds & meaninings of Qi in Lee Je-Ma's writings. 2. Methods We analyzed Lee Je-Ma's writings which contain the related contents of Qi's kinds & meanings 3. Results and Conclusions 1) There are distinctive Qi features of $sorrow{\cdot}anger{\cdot}joy{\cdot}pleasure$(哀怒僖樂) which are different from one of seven mode emotions(七情) in ${\ulcorner}$Gyukchigo(格致藁)${\lrcorner}$. 2) When $Water{\cdot}grain's$ Qi(臟氣) is the base of the human's Qi, $Nature{\cdot}emotion's$ Qi(性${\cdot}$情氣) is managing. And $Lung{\cdot}Spleen{\cdot}Liver{\cdot}Kidneys's$ Qi(肺脾肝腎氣) is the representative concept resulted by the complex operation of $Water{\cdot}grain's$ Qi(水穀之氣) and $Nature{\cdot}emotion's$ Qi. Each Qi stands for its protensity as follows ; Lung's Qi for extrorse propensity of Yang(Z), Spleen's Qi for upward propensity of Yang(陽), Liver's Qi for introrse propensity of Eum(陰), Kidneys's Qi for downward propensity of Eum(陰). 3) Jang's Qi is more important than medicine's Qi and medicine's Qi has a limitation about recovering jang's Qi. So that it is very important to take care of one's mind. 4) Controling mind Qi is controling Nature & emotion's Qi. Thus controling mind Qi si the best plan for jang's Qi and controling with medicine's Qi is the next policy. 5) Qi influences all aspect of personality, disease, application of medicines and ordinary symptoms. So that Qi is the kernel of the Sasang Constitutional Medicine.

  • This study were obtained elapsed time phase-by-phases, displacement, user angle, velocity and angular velocity to analyse kinematically contributing factors at impact of forehand drive motion, on targeting three male players. The results of the study were presented as follows; In the forehand drive swing, the elapsed time by phases was a total of .52 seconds: .30 seconds from backswing to impact and .22 seconds from impact to follow-through, Considering the mean change in locations of COM of each(part$\rightarrow$body segment) at impact, racket head, left shoulder, right wrist and left hip, the left-right directions(X-axis) were showm to be each $.61{\pm}.03$, $1.19{\pm}.08$, $.66{\pm}.03$, $.94{\pm}.06$, and $.45{\pm}.03m$. The displacement differences of COM of each body segment were shown to be -.57, -.05, -.33, and .16m. For the vertical direction(Z-axis), the center of mass was lowest at impact and highest at E3. For the displacement of the right wrist on the left hip, the right wrist moved to .82m to the lower direction without change in the locations of the hip from E1 from E2. When the left hip moved .02m from E2 to E3, the right wrist moved .7m in the upper direction. In respect to the velocity of each body segment, the hip and the shoulder joint accelerated and then the wrist followed. Then the right wrists of all the subjects and their racket heads showed maximum speed, and an effective swing was observed. At the angle of each part, the angle of the right wrist was the smallest at the backswing and the largest at the moment of the impact. Then it increased gradually in the follow-through section. In respect of angular velocity for subject A, the hip moved and the largest change occurred. Immediately before the impact, the subject made a swing using his right wrist, his hip, and the shoulder joint, showing the maximum value, which was judged to be effective.

  • Quantitative determination of sulforaphane, S-methylsulfinylbutyl isothiocyanate in 20 cruciferous vegetables of Korean origin was performed. Homogenate of vegetable was extracted with dichloromethane, and the extract, after drying, was subjected to GC/MS analysis, which was based on single ion monitoring (SIM) at m/z 72, 160, 55, 114 and 177. The content of sulforaphane was found to be the highest in the extract of broccoli $(80.2{\sim}617.7\;ppm)$ followed by turnip $(15.4{\sim}23.1\;ppm)$, red cabbage $(9.9{\sim}32.1\;ppm),\;radish\;(5.5{\sim}8.8\;ppm)$ and kale (8 ppm). Among various cultivars of broccoli, broccoli '1243' and broccoli 'Pilgrim' showed higher content of sulforaphane than others. Especially, in the stem of broccoli '1243' and the floret of broccoli 'Pilgrim' the amount of sulforaphane was the highest (>700 ppm). Thus, the content of sulforaphane differed according to the cultivars and the portion of the vegetables.

  • Approximately 2.0 kb of the promoter region of the Pichia pastoris phosphoglycerate kinase gene (PGK1) was reduced to a 266 bp fragment and this minimized portion was used for construction of a new episomal constitutive expression vector in P. pastoris. As an approach to developing a constitutive expression vector in P. pastoris, the GAP promoter region of the Pichia expression vector pGAPZB was replaced with sequentially deleted PGK1 promoter fragments fused to a beta-galactosidase gene. When a lacZ gene was used as a reporter gene, PGK1 promoter strength was lower than that of the constitutive GAP promoter but it was higher than TEF1. We report here the development of the pPGKZ-E vector as a new episomal expression vector for heterologous gene expression by removing non-essential regions of the PGK1 promoter. This broadens the choice of episomal expression vectors for controlled constitutive expression in P. pastoris.

  • The metalloid arsenic (Z = 33) is considered to be a significant potential threat to human health due to its ubiquity and toxicity, even in rural regions. In this study a rural region contaminated with arsenic, located at longitude $85^{\circ}$ 32'E and latitude $25^{\circ}$ 11'N, was initially examined. Arsenic tolerant bacteria from the rhizosphere of Amaranthas viridis were found and identified as Bacillus licheniformis through 16S rRNA gene sequencing. The potential for the uptake and removal of arsenic at 3, 6 and 9 mM [As(V)], and 2, 4 and 6 mM [As(III)], and for the reduction of the above concentrations of As(V) to As(III) by the Bacillus licheniformis were then assessed. The minimal inhibitory concentrations (MIC) for As(V) and As(III) was determined to be 10 and 7 mM, respectively. At 3 mM 100% As(V) was uptaken by the bacteria with the liberation of 42% As(III) into the medium, whereas at 6 mM As(V), 76% AS(V) was removed from the media and 56% was reduced to As(III). At 2 mM As(III), the bacteria consumed 100%, whereas at 6 mM, the As(III) consumption was only 40%. The role of pH was significant for the speciation, availability and toxicity of the arsenic, which was measured as the variation in growth, uptake and content of cell protein. Both As(V) and As(III) were most toxic at around a neutral pH, whereas both acidic and basic pH favored growth, but at variable levels. Contrary to many reports, the total cell protein content in the bacteria was enhanced by both As(V) and As(III) stress.

  • We examine large-scale environmental effects on the formation and the mass growth of dark matter halos. To facilitate this, we constructed dark matter halo merger trees from a cosmological N-body simulation, which enabled us to trace the merger information and the assembly history of individual halos. In fact, since the massive halos are more likely to be distributed in denser regions than in less dense regions (Mo & White, 1996), the large-scale environment dependence of the properties of halos can be partly originated from the halo mass effect. In order to avoid such contamination, caused by the mass dependence of halo properties, we carefully measured the local overdensity as the indicator of large-scale environment, which was calculated to be as independent of halo mass as possible. Small halos (${\sim}10^{11-12}M_{\odot}$), which usually host isolated single galaxies, show a notable difference on the formation time of galaxies depending on their large-scale environments, which reconfirms halo assembly bias (Gao & White, 2007). Furthermore, we investigate how this environmental effect on small halos is correlated with the mass assembly history of galaxies by using our semi-analytic model. We found that assembly bias in small halos does not have significant effects on the formation time or on the star formation history of galaxies residing in those halos except for the individual stellar mass of galaxies at z = 0. On average, isolated galaxies in high-density regions tend to be slightly more massive than those in low-density regions. Although the observational data from the current galaxy surveys is not yet sufficient for testing this prediction, future galaxy surveys will be able to explore these small galaxies more thoroughly.

  • The properties of bright galaxies are closely related to those of their nearby neighbors and satellite galaxies. In addition, the properties of galaxies in clusters are known to be strongly affected by the cluster environment. These two environmental effects raise a question: how significantly do nearby neighbors and satellite galaxies affect the properties of bright galaxies in a cluster? To address this issue, we reduce and analyze the deep and wide-field images of Abell 3659 (z ~ 0.0907) in the g' and r' bands obtained using IMACS on the Magellan (Baade) 6.5m telescope. The main goal of this study is to find out the relationship between the properties of bright galaxies and those of fainter companion galaxies in a cluster. This poster is a progress report, in which we present the sample selection and the preliminary results.

  • This study analyzes the results of thunderstorm data observed in the mid-western part of Japan during the winter of 1996-1997. There were 35 instances of thunderstorms with 4,426 instances of lightning detected during the observation period. This study estimates the frequency of lightning occurrence through classification of detected lightning into two types, and analyzes the relationship between lightning types and synoptic pattern. According to the analyzed results, cloud-to-cloud discharge and positive polarity occupied 78% and 42.3% of total discharge, respectively. It is rare for lightning to occur in the winter season, usually occuring during the night (midnight to 5 a.m.). Lightning frequently occurs when there is a prevailing synoptic wind from the norhwest. According to the analyzed results of multiplicity and multi-point lightning, the mean values of multiplicity and multi-point lightning are 1.4 and 1.2, respectively.

  • The purpose of this study was to show the method of three-dimensional morphometry developed recently and to compare the accuracy of three-dimensional morphometry with those of PA cephalometry, The three-dimensional morphometry analysis program and device were developed. Steel balls (1.2mm in diameter) were attached in twenty five landmarks of artificial human skull. This artificial human skull was used as experimental materials. From three-dimensional morphometry and PA cephalometry of artificial human skull. eleven linear measurements were acquired and made into asymmetry index. Right-left differences of measurements were used as asymmetry index. These measurements and asymmetry index were compared respectively with those of actual. The results were as follows: 1. Mean difference between three-dimensional morphometry and actual artificial human skull in linear measurements was $1.99{\pm}0.37mm$, and mean difference between PA cephalometry and actual was $21.12{\pm}0.45mm$. Both of all were reduced more than those of actual. 2. Mean difference between three-dimensional morphometry and actual artificial human skull in asymmetry index was $0.07{\pm}0.42$, and mean difference between PA cephalometry and actual was $3.63{\pm}0.60$. Three-dimensional morphometry was reduced while PA cephalometry was magnified more than that of actual. 3. Each eleven asymmetry index of three-dimensional morphometry was the same negative sign as those of actuals while only N-Z, ANS-J, Tr-Go, Tr-ANS asymmetry index were the same in PA cephalometry. These results suggest that the method of three-dimensional morphometry is more accurate than those of PA cephalometry in asymmetry analysis.

  • PURPOSE. This study evaluated the influence of prosthesis weight and number of implants on the bone tissue microstrain. MATERIALS AND METHODS. Fifteen (15) fixed full-arch implant-supported prosthesis designs were created using a modeling software with different numbers of implants (4, 6, or 8) and prosthesis weights (10, 15, 20, 40, or 60 g). Each solid was imported to the computer aided engineering software and tetrahedral elements formed the mesh. The material properties were assigned to each solid with isotropic and homogeneous behavior. The friction coefficient was set as 0.3 between all the metallic interfaces, 0.65 for the cortical bone-implant interface, and 0.77 for the cancellous bone-implant interface. The standard earth gravity was defined along the Z-axis and the bone was fixed. The resulting equivalent strain was assumed as failure criteria. RESULTS. The prosthesis weight was related to the bone strain. The more implants installed, the less the amount of strain generated in the bone. The most critical situation was the use of a 60 g prosthesis supported by 4 implants with the largest calculated magnitude of 39.9 mm/mm, thereby suggesting that there was no group able to induce bone remodeling simply due to the prosthesis weight. CONCLUSION. Heavier prostheses under the effect of gravity force are related to more strain being generated around the implants. Installing more implants to support the prosthesis enables attenuating the effects observed in the bone. The simulated prostheses were not able to generate harmful values of peri-implant bone strain.
