Objective: To derive information on the efficacy of Sam-chul-kun-bi-tang (SKT), by evaluating its anti-inflammatory effect. SKT is a widely-used herbal formula in traditional Korean medicine. In man y studies, plant-derived anti-inflammatory efficacies have been investigated for their potential inhibitory effects on lipopolysaccharide (LPS)-stimulated macrophages. This study was performed to examine the anti-inflammatory effects of SKT extract on LPS-stimulated RAW 264.7 cells. Methods: The production of nitric oxide (NO), prostaglandin $(PG)E_2$, tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6 were examined in a macrophage cell line, RAW 264.7 cells, in the presence of SKT. RAW 264.7 cells were incubated with LPS 1 ${\mu}g/mL$ and SKT for 18 hrs. The anti-inflammatory activity of SKT was investigated by carrageenan-induced paw edema in rats. The paw volume was measured at 2 and 4 hrs following carrageenan-induced paw edema in rats. Results: SKT showed inhibitory effect on $PGE_2$, TNF-$\alpha$ and IL-6 in LPS-stimulated RAW 264.7 cells. But SKT was not inhibitory effect on NO by LPS-stimulated RAW 264.7 cells. Administration of SKT (1 g/kg) also showed a reduction in carrageenan-induced paw edema on rats. Conclusion: These results suggest that SKT has anti-inflammatory activities in both in vitro and in vivo models.

Objectives : The purpose of this study was to examine the effects of the Astragali radix Pharmacopuncture on improvement of senile osteoporosis (Type 2) in SAM P6. Methods : At 10 weeks after birth, Astragali radix Pharmacopunctures were given 100mL, 200mL/kg/day, i.p. 3times a week for 4 weeks at $CV_{12}$ in SAM P6 mice. We measured complete blood cells (CBC) such as RBC, HGB, Hct, PLT, MPB and MCHC. And we analyzed the plasma concentrations of blood urea nitrogen, creatinine, inorganic phosphate and total iron. In addition, we tested bone mineral density (BMD) using the soft X-ray. Results : The results were as follows. 1. At $CV_{12}$ in SAM P6, treatments of Astragali radix Pharmacopuncture were showed a trend of increase in bone mineral density (BMD) of the vertebrae lumbales, femurand tibia in P6 mice. 2. At $CV_{12}$ in SAM P6, treatment of Astragali radix Pharmacopuncture increased in RBC, HB, HCT and PLT, in comparison with control group. It was also found that the inorganic phosphate levels increased in the treatment on groups of the Astragali radix Pharmacopuncture from that of the control group, but blood urea nitrogen was no significant. Conclusions : These results are suggested that at $CV_{12}$ the Astragali radix Pharmacopuncture help on improvement of osteoporosis in SAMs.

At early Cheong (淸) dynasty, in medical aspect by dependent on practical studying attitude that must found a theory only by an evidence, there had been a tendancy that hoped direct research of sages' mind-eye by escaping the theory of individual classes since Geum-Won (金-元) dynasty. Yoo Chang (喩昌), born in Man-Ryeok (萬曆) 12th year of Myung (明) dynasty (A.D.1583) and dead in Gang-Hee (康熙) 3rd year of Cheong (淸) dynasty (A.D.1664). The results were as follows after studying his practical idea of medicine. 1. Yoo Chang, by recognizing the ${\ll}$Sang-Han-Ro${\gg}$ has lost its true meaning after commented by Wang Hee (王熙), Lim Eog (林億), Seong Moo-I (成無巳), etc. according to Bang Yoo-Jip's (方有執) Chak-Gan-Jung-Jeong (錯簡重訂) theory, he diversified the protocal of ${\ll}$Sang-Han-Ro${\gg}$ 397 method and arranged under Six Meridian part. (六經) 2. The theory of Sam-Gang-Jeong-Rip (三綱鼎立) can be summerized Gye-Ji (桂枝) syndrome which is the case of Wind (風) has injured Wi (衛) stage, Ma-hwang (麻黃) syndrome which is the case of Cold (寒) has injured Yeong (榮) stage, Dae-Cheong-Ryong (大靑龍) syndrome which is the case both of Wind-Cold (風寒) has injured Yeong-Wi (榮衛) stage, and there has been Sam-Gang-Jeong-Rip theory by anterior medical practitioners already but the person who formally used its Sam-Gang-Jeong-Rip term is Yoo Chang. 3. Yoo Chang seized the On Byeng (溫病) by dividing three category and in Byon-Jeung-Si-Chi (辨證施治) he influenced to many aspect of establishment of later Byon-Jeung system On-Byong (溫病의 辨證體系) pertaining to Triple-Warmer by O-Dang (吳瑭) introducing Triple-Wanner Theory. (三焦理論) 4. At Chu-Jo-Ron (秋燥論) of ${\ll}$EUi-Moon-Beop-Ryo${\gg}$, while ${\ll}$Nae-Gyeong${\gg}$ describing if humidity injury Lung, then occur a disorder in it, Yoo Chang recognized that of au tuam when dryness injure Lung there occure a disorder is it so he insisted that at this case, must use Cheong-Joe-Goo-Pye method (淸操救肺法) withherbs, pertaing to Gam-Yoo-Ja-Yoon(甘柔滋潤性) property and he invented Cheong-Joe-Goo-Pye-Tang. (淸操救肺湯) 5. Yoo Chang', so called, Dae-Gi (大氣) indicates Yang-Gi (陽氣) of chest, he insisted that man's creation and every physiological activity depends on maintainence of Dae-Gi, and it integrate Yeong-Gi (榮氣), Wea-Gi (衛氣), Jong-Gi (宗氣), Jang-Boo-Ji-Gi (臟腑之氣), Gyeong-Rak-Ji-Gi. (經絡之氣) 6. Yoo Chang's expression about partical function and character of stomach, not only bolster its theory of historical physician's expression, that is stomach is. foundatness of postnatal period, but also it has corresponding aspect with modern medicine and clinic. 7. Yoo Chang emphasized "if one cure a disease, be must understood the character of disease first and use drugs later" (先議病 後用藥) phrase about of drug usage, and his theory of Geup-Rew-Man-Joo method (急流挽舟) and three therapy of Simple Ascite (單腹腸) are all unique opinion based upon this phrase mentioned above. 8. Yoo Chang's practical idea of medicine greatly influenced to Jang Ro (張璐), Hwang Won-A (黃元御), Oh Eui-Rak (吳儀洛), Joo Yang-Joon (周揚俊), etc. and theory of Sam-Gang-Jeng-Rip (三綱鼎立), Triple Warmer Theory of On Byong (溫疫의 三焦論治), Chu-Jo-Ron (秋燥論), Dae-Gi-Ron (大氣論) etc. became important object to student of Sang-Han (傷寒) and On-Byeng. (溫病) 9. Yoo Chang's Writings has more practical meaning than other physician's, especially, later the idea of Sang-Han (傷寒) and On-Byong (溫病) greatly contributed to development of Sang-Han theory and formation of On-Byong theory.

Im $gegew\"{a}rtigen$ Deutschen gibt es zwei verschiedene Auffassungen $\"{u}ber$ das adjektivische Wortbildungsmorphem -Ios. $W\"{a}hrend$ -Ios einerseits als Halbsuffix betrachtet wird, will man es andererseits als Suffix betrachten. Die $Gr\"{u}nde$, die -Ios als Halbsuffix gelten lassen, sind die folgenden : 1. Es besteht eine semantische Verwandtschaft zwischen -Ios und dem freien Morphem Ios. 2. Anders als Suffix hat es ein $zus\"{a}tzliches$ semantisches Merkmal. 3. Die Bildungen mit -Ios haben die Fugenelemente. 4. Es konkurriert mit adjektivischen Halbsuffixen. Die $Gr\"{u}nde$, die -Ios als Suffix gelten lassen, sind die folgenden: 1. Im Unterschied zu -frei und -leer dient es zur wertungsneutralen Feststellung des Sachverhalts 'Nichtvorhandensein'. 2. Es besitzt eine einheitliche semantische Funktion. (BS+ -Ios = ohne BS) 3. Es $geh\"{o}rt$ zur Lautstruktur 'KVK'. Diese entspricht der Lautstruktur der adjektiven Suffixe -bar, -lich. -sam usw. Diese verschiedenen Merkmale von -Ios lassen das Morphem noch nicht als Suffix gelten.

This paper proposes a new operation algorithm for elevator by considering both better service for passengers and minimization of energy consumption for elevator operation. The main idea of the proposed operation algorithm is based on the assumption that passengers push the numbered buttons indicating their destination, one of the main differences of proposed operation mode from the conventional one is that the elevator may move to the opposite direction for a few floors according to the rescheduled operational pattern determined by some factors. Some examples by computer simulation show the efficiency of the proposed operation algorithm.

We present a powder injection molding technique of fabricating cemented tungsten carbide(WC) balls for milling and dispersing nano-powder in this paper. The conventional powder metallurgy approach is investigated to reveal its drawbacks of density non-homogeneity. New procedures of powder injection molding for the homogeneous high-precision WC balls, involving the binding process, powder injection molding process and sintering process, are presented in detail. Each process is investigated empirically and numerically to obtain its engineering information, which can used for process optimization.
