For the efficient co-authoring of multimedia documents in a distributed systems environment, the cooperative-work management systems that can not only allow the sharing of distributed resources but also facilitate the authors' interaction, are needed. In this paper, we present a cooperative-work management system with hybrid architecture, called CW-MAN, in which the information on shared objects and co-authoring management is stored in a dedicated computer system but the shared objects distributed all over the local computer systems. The main management functions provided by the CW-MAN are those for shared objects, session, and telepointing. The shared-object use them exclusively. The session managements allows authors to dynamically create, update, and destroy sessions. Lastly, the telepointing management allows local pointing events to be synchronously presented to remote systems.

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.

Sam Shepard is one of the leading American playwrights who represented Off-Off Broadway in the l960s and 1970s. In his early days, he wrote many experimental plays but later he turned to realism. However, under the superficial realism in his later plays, we find that they contain experimental devices and themes. True West (1980) is the last play of ills realistic family trilogy. This play shows that the tradition of Old West, which is symbolized and replaced by desert, disappeared in the industrialized clues of modern West. The Old West is compared which the modern West through the struggle of two brothers, Lee and Austin. Their father, 'Old Man', ran out on his family and went to the desert but did not succeed there. He shows that he failed in achieving the American Dream. The family appears unusual and demolished The relationships of the characters are not based on love and belief. The family symbolizes the negative aspects of modern American society. After Austin recognizes the actual situation finding that there is no real life in the modern West, he tries to leave the city and his family. He wants to go to the desert in search of a new life. However, in the last tableau Lee blocks the exit and the two brothers square off. It implies that they are doomed to continue their struggle. The message Implies that American society today is lacking the same positive values they once had in the Old West.

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.

Doping of boron atoms in graphite has been well known method to increase the discharge capacity as the negative electrode material for lithium secondary battery. Herein, the boron-doped graphites are prepared by mixing 1, 2.5, 5, and 7 wt. % of boron carbide in carbon during the graphitizing process. The structural states of boron in boron-doped graphites are investigated by solid-state 11B NMR spectroscopy. The resonance lines for substitutional boron atoms are identified as the second order quadrupolar powder pattern with the quardrupole coupling constant, QCC = 3.36(2) MHz. The quantitative analysis of 11B NMR spectra with boron-doped graphite has also been performed via simulation.

In the past, a mobile phone had only a function of communication. Recently, new functions such as an mp3 player and a camera are added in a mobile phone. For the application of a camera module to a mobile phone, the size of the camera module needs to become smaller than a general Digital Camera. Furthermore, it is also required that the performance of the camera module in a mobile phone be the same as that of a Digital Camera. In order to fulfill these requirements, the camera module should have functions such as Auto Focus, Zoom, the shutter and the aperture. Therefore, we introduce a simple and effective actuator and propose the shutter composed of solenoid.

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.

A 36-year-old man, who had undergone thoracoscopic anterior spinal fusion using the plate system and posterior screw fusion three months previously, presented to our hospital with left flank pain and fever. Computed tomography indicated the presence of a psoas muscle abscess. However, after two days of percutaneous catheter drainage, a mycotic abdominal aortic pseudoaneurysm was detected via computed tomography. We performed in situ revascularization using a prosthetic graft with omental wrapping. Methicillin-resistant Staphylococcus aureus was identified on blood and pus culture, and systemic vancomycin was administered for one month. Although the abscess recurred, it was successfully treated with percutaneous catheter drainage and systemic vancomycin administration for three months, without the need for instrumentation removal. The patient remained asymptomatic throughout two years of follow-up.
