As more and more advanced technology implemented in Computer Game, various of technical skill must be applied to satisfy the demand of the users specifically in the immersion and convenience of the games. As a result, The number of interactive games, which are controlled by user's physical action so that make the games more immersible, are increasing. In Addition, as the amount of information that happens in the games increases, many studies are going on to provide efficient user-interface. In this study, we develop an interactive game using a controller designed by us, which consist of Wii controller and an attached secondary display that provides game information to user. In addition, we conduct a survey with questions about immersion and convenience of the game to understand how users feel when doing the suggested game, and to compare our game environment with general FPS game environment that uses mouse and keyboard.

As an information-oriented society comes, many people use PC and depend on database that network server has. However, the online data can be missed when a blackout happens and also a power failure effects on standard of judgment on Power Quality. Thus, it is reason of a trend using interruption-free live-line work when a trouble happens to power system. However, the 83％ among the number of people who receive an electric shock experience when a laborer is doing interruption-free live-line works. In interruption-free method, the education and the training problem has been issued. However, we have a few instructors for that training. Furthermore, the trainees have short training period, just 4 weeks. In this paper, to develope the method that has no restriction of a time and place and reduce the wasteful materials, immersion type virtual reality(or environment) technology is used. The users of a 3D immersion type VR training system can interact with the system by doing same action in the real safe environment. Thus, it can be valuable to apply this training system to a dangerous work like as "Interruption-free live-line work exchanging COS(Cut-Out-Switch)". In this program, the user works with a instruction on the window and speaker and can't work other tasks until each part of the task completed. The workers using this system can use their hands and viewpoint movement as he is in a real environment but the trainee can't use all parts and senses of a real body with the current VR technology. Despite of this weak point, when we consider the trends of improvement in electrical devices and communication technology, we can say that 3D graphic VR application has a high potentiality.

The effects of methanol and water extracts of Taheebo were investigated on gastric secretion, gastric lesion and ulcer in rate. Experimental gastric lesion and ulcer was produced in rats using the following methods : HCl.aspirin-induced lesion, HCl.ethanol-induced lesion, indomethacin-induced ulcer and water-immersion stress ulcer model. In addition, the amount of gastric secretion in pylorus-ligated rats for 4 hours was determined. Water extracts of Taheebo significantly inhibited HCl.aspirin-induced gastric lesion at 1,000mg/kg, po in rats. Likewise, Water extracts of Taheebo caused significant inhibition of indomethacin-induced ulcer at oral dose of 1,000mg/kg. The lesion induced by HCl.ethanol was significantly reduced by both water and methanol extracts of Taheebo. It also showed significant antiulcer activity in water-immersion stress ulcer, respectively. In gastric secretion experiments, methanol extracts of Taheebo also showed significant inhibition of gastric juice secretion, acidity and acid output at doses 500 and 1,000mg/kg. These results may suggest that Taheebo shows antigastritic and antiulcerative action in rats in part by the inhibition of gastric juice secretion and acidity.

Alnus japonica Steud (A. japonica) have long been used in the traditional medicine for gastric disorder, hepatitis and fatty liver in Korea. Antiulcer effects of A. japonica hot water extract (AJ ext) were evaluated by in vitro antibacterial activity against H. pylori, by the inhibitory action against the in vitro gastric $H^+/K^+$-ATPase and using rat models of gastric mucosal damage and gastric ulcer induced by HCl-ethanol, indomethacin, and restraint and water-immersion stress. For the determination of antibacterial activity of AJ ext against H. pylori, the activity of urease which released from H. pylori was measured in culture. AJ ext showed weak antibacterial activity against H. pylori with the growth inhibitions of 37% and 61% by adding final concentrations of 500 and $1000{\mu}g/ml$ culture, respectively at 24 h. To observe the inhibitory activity of AJ ext against the $H^+/K^+$-ATPase in hog gastric membrane vesicle, $IC_{50}$ value of AJ ext was $806.3{\mu}g/ml$. Pretreatment of AJ ext (200, 500 mg/kg, p.o.) prevented in a dose-dependent manner the acute gastritis in HCl-ethanol model and the formation of gastric ulcer in indomethacin model and restraint and water-immersion stress model. These results suggest that the AJ ext can be used for prevention and treatment of gastric mucosal damage and ulcers induced by various stress.

The method of operating a game could determine the psychological distance between the player and the game character, and thus, in the Virtual Reality, players' control methodologies are important to enhance their immersion. This study has the objective of examining the difference in games according to the method of operation based on the player's movements. This study researched the effect of the method of operating movement conforming to the movement of the character and the physical operation of the body on forming game experiences for the player. The result of performing an experiment increased reality for the game player through a controller in the shape of the actual control, to increase focus in the game. As so, game play through movements, including actual movements by the player displayed to enhance game satisfaction. In the part of media remediation field, Game can be defined as media which has their own unique hypermediacy. Especially, in the motion based game, players' movement mediates players and the game, therefore, players' movement could make players' experience augmented or immediate in accordance with the characteristics of movements. Even though sports and dances genres of motion-based games are common, RPG or adventure genres are rare. It can be explained that the characteristics of the action have been explained in the immediacy. In a game of fantasy, which is difficult to experience in real-life situations, the nature of the player's motion can increase the immersion of the game, which can contribute to utilization of players' motion and experience design in the various genres and suggestion of grounds theory. In addition, through this study, it is able to design motion-based games of various genres.

This article aims to research and analyze expressional characteristics of media art in Hussein Chalayan's fashion works. Media technology has made rapid progress over every society, in which it enables multi-dimensional communication. Under this social background, media art can use a multiplicity of technologies and go public. Media art had great influences in fashion with the leading designer as Hussein Chalayan. His works has been selected from the 90s up until 2008 focusing on expressional characteristics of media art by a professional group of fashion design. By classifying and analyzing of Hussein Chalayan's fashion works, expressional characteristics of media art displayed from works of the late 90s, and in recent years, the use of various technologies has increased. Expressional characteristics of media art in his works have been re-classified as interactivity, transfonnation, visualization, and transparency. First, interactivity by the wearer's action and emotional change is effective on emotional express, body protection and the causing of interest. Second, transfonnation by the wearer's action, functioning, and emotional change is influenced by convenience, body protection, and causing concern. Third, immateriality in media art is divided into visualization and transparency, and in fashion structural and material characteristics. Visualization by internal luminous source and digital images influences immersion and expression on fantasy images. Fourth, transparency by immaterial characteristics and piled up images affects openness and camouflage. Development of material and technology paves the way for expressional characteristics of media art in fashion. The trend of Hussein Chalayan's works moves towards emotional high-tech design with technology.

Computer games must keep the user immersed for fun. According to the immersion theory, maintaining the user's immersive state requires a continuous balance of game skill level and game difficulty level This study proposes a game skill estimation method of 9th grade that can be applied to a casual action game that can assume a zero-sum game, and additionally proposed a difficulty guessing method. The proposed methods can be implemented quickly and easily because it is a method determining by conditional mathematical expressions. Experiments on the accuracy of the proposed methods for the customized Pac-Man game show that the accuracy of the skill level was 1.2 grade as the difference on the average and the accuracy of the game difficulty level was 1.81 grade the difference on the average. The results show that the proposed methods are accurate enough to be applied to casual action games satisfying the zero-sum condition.

The pet ether extract of Caesalpinia pulcherrima, leaves was studied for its antinociceptive, anti-inflammatory and antipyretic property. The extract at doses of 50 and 200 mg/kg, p.o., significantly (p<0.05) reduced the number of writhing induced by acetic acid and inhibited the late phase (20-30 min) in formalin test in mice. The extract failed to increase the pain threshold level in tail immersion test in mice. In carrageenan induced paw edema in rats and in acetic acid induced increase in vascular permeability test in mice, the extract (50-600 mg/kg, p.o.) failed to produce any significant activity. While in cotton pellet granuloma test, the extract at doses of 200 and 600 mg/kg (p.o.) significantly (p<0.05) reduced the granuloma formation and was comparable to reference drug, dexamethasone. In ethylpheylpropiolate ear edema test 0.5 mg and 1 mg/ear application of extract significantly (p<0.05) inhibited ear edema. In yeast induced hyperthermia in rats, the extract did not produce any reduction in temperature. The results suggest that the extract acts peripherally to produce analgesic action and anti-inflammatory activity through steroidal mechanism.

Two azole compounds viz., Imidazole (IM) and 2-Methylimidazole (2-MIM) were studied to investigate their inhibiting action on corrosion of mild steel in phosphoric acid ($H_3PO_4$) solution by mass loss and polarization techniques at 302K-333K. It has been found that the inhibition efficiency of the all inhibitors increased with increase in inhibitor concentration and decreases with increasing temperature and also with increase in acid concentrations. The inhibition efficiency of these compounds showed very good inhibition efficiency. At 0.5% of IM and 2-MIM in 1N and 5N phosphoric acid solution at 302K to 333K for 5 hours immersion period, the inhibition efficiency of 2-Methylimidazole found to be higher than Imidazole. The adsorption of these compounds on the mild steel surface from the acids has been found to obey Tempkin's adsorption isotherm. The values of activation energy ($E{\alpha}$) and free energy of adsorption (${\Delta}G{\alpha}ds$) were also calculated. The plots of log $W_f$ against time (days) at 302K give straight line which suggested that it obeys first order kinetics and also calculate the rate constant k and half life time $t_{1/2}$. Surface was analyzed by SEM and FITR spectroscopy.
