  • Wogonin(5,7-dihydroxy-8-methoxyflavone), an anti-inflammatory plant flavonoid, was previously demonstrated to modulate the several parameters of animal skin inflammation. This compound inhibited edematic response as well as proinflammatory gene expression. In this investigation, the histopathological changes of the lesions from different types of experimental skin inflammation were compared and the potential therapeutic effect of topically applied wogonin was evaluated. From the results, it was found that multiple TPA treatment drastically increased ear edema accompanied with epidermal hyperplasia and inflammatory cell infiltration, while phenol treatment provoked only edematic response in the dermal area. Wogonin somewhat differently inhibited these animal models of skin inflammation.

  • It is important to maintain good habitual posture in daily life. Abnormal body aligament is provoked by excessive tension of bad posture. And these symptom is connected with other disorder of the body like back pain, cervical pain and shoulder pain through inaccurate body mechanism in daily life. This study was searched to figure out effects of factor that how to balance good posture and normal posture. And the other purpose of this study was to make new calculate device for analysis of effective posture in clinic.

  • The issue of safety insurance in PES(Programmable Electronic Systems) has been provoked because PES is difficult to define failure modes which are appeared in many different ways. But the PES applications extend rapidly in various areas. One of the solutions for PES safety insurance is voting which PES is used by comparing the outputs of several PES. The time synchronization of the PES is necessary for this reliable voting. The voting must be carried out with the outputs from same time inputs. There are several methods for time synchronization of the PES. In this paper, we discussed two modes of the time synchronization which are mutual synchronization of several PES and using UTC(Universal Time Clock).

  • The glomus tumor of the peripheral nerve is one of the mesenchymal tumors originating in the epineurium, and is extremely rare. A 56-year-old man presented complaining of lancinating pain on the left thigh, which was provoked by pressure or exercise. Subsequent image study revealed a mass in the femoral nerve. Total surgical excision with the aid of intraoperative ultrasonography was performed and the pain was successfully controlled. The authors report an unusual case of a patient diagnosed with glomus tumor in peripheral nerve, with a review of the clinical features, imaging, and pathological findings.

  • As a brush DC motor, the brushless DC motor is also operated by DC power supply but has no mechanical contacts occurred by a brush or a commutator. Though the performance of BLDC motor is almost similar with that of DC motor, the BLDC motor has the advantage of the high speed responsibility, the high controllability, and the high effectiveness. The control valve using the BLDC motor, which excludes the burnout effect provoked possibly by the vacuum condition during the flight, is employed for the upper stage of a launch vehicle. For the component level analysis, the dynamic response characteristics of BLDC and DC motors to the same design input sources have been studied in using AMEsim.

  • Experimental studies were done to research the clinical effects of Biahwan and Sutodan on the Anti-allergic Effect in Rats and Mice. The results were summerized as follows; 1. In the 48hours homologous passive cutaneous anaphylaxis in rats provoked by the IgE-like antibody against egg white albumin, Biahwan and Sutodan revealed significant effects. 2. In the effects of Biahwan and Sutodan on vascular permeability responses to intradermal histamine and serotonin in rats, Biahwan revealed significant effect, but Sutodan revealed none significant effect. 3. In the delayed type hypersensitivity responses to Picryl Chloride in mice, Biahwan and Sutodan revealed none significant effects. 4. In the delayed type hypersensitivity responses to SRBC (Sheep Red Blood Cell) in mice, Biahwan and Sutodan revealed significant effects.

  • The purpose of this study is to estimate human sensibility quantitatively under color stimulation. We measured biological signals such as EEG, ECG, skin conductance and the number of respiration and eye blinking that were compared with color sensibilities mutually. Our result showed that red, yellow and violet color provoked active and exciting senses dominatively and blue, cyan, pink, and black color were involved in tranquil and resting emotions deeply. Our quantitative estimations of color sensibilites are useful in the design of manufactured goods and color therapy.

  • Twenty seven plant extracts were selected on the basis of ancient literature search for rheurnatoid arthritis or similar syndrome. Methanol extract of each plant was prepared and administered orally to rats everyday at a dose of 200 mg/kg/day. Experimental arthritis was induced by subplantar injection of heat-killed Mycobacterium butyricum to right hind paw of rats. This treatment provoked swelling of the treated paw in two phases, acute primary swelling and secondary arthritic swelling. An inhibition of secondary swelling was considered to be antiarthritic activity. Several plant methanol extracts such as Akebia quinata (caulis), Ephedla sinica (herba) and 5ophorae subprostratd (radix) were found to show significant inhibitory activity against secondary swelling at the dose tested. Our results strongly suggested an antiarthritic potential of these plant extracts.

  • Damages by vibration and noise due to the construction performance are increasing. The rise of construction demand and enlargement of equipments are major reasons of this damage. As a result, the enmity of the people is provoked and this appears to be an obstacle of construction work. Especially, in case of ground improvement construction. Casing pipe is inserted into the Sand Drain, Sand Compaction Pile and Vibrated Crushed-stone Pile by vibration power when carrying out. Hence, a pillar is formed and it creates vibration and noise. This causes a lot of restrictions to construction condition. The low Vibration and low noise construction equipments uses earth auger and hydrulic cylinder for insertion and chopping operation instead of vibro hammer, which is the source of vibration and noise. This minimize ground disturbanceand decrease vibration and noise successfully, but increase chopping effect greatly. Thus, this new equipment is not only suitable for environment but also excellent engineering method of construction.

  • Many simulation models have been built to facilitate simulation technique in designing, evaluating, and optimizing supply chains. Simulation is preferred to deal with stochastic natures existing in the supply chain. Moreover simulation has a capability to find local optimum value within each component through entire supply chain. Most of supply chain simulation models have been developed on the basis of discrete-event simulation. Since supply chain systems are neither completely discrete nor continuous, the need of constructing a model with aspects of both discrete-event and continuous simulation is provoked, resulting in a combined discrete-continuous simulation. In this paper, an architecture of combined modeling for supply chain simulation is proposed, which includes the equation of continuous portion in supply chain and how these equations are used in the supply chain simulation models. A simple example of supply chain model dealing with the strategic level of supply chain presented in this paper shows the possibility and the prospect of this approach.
