Despite the advancement of knowledge and techniques, architectural design has been developed by similar method and science as the logical tool since the development of Le Corbusier's 'module'. However, in the new millenium emotional design has become a key issue and today is the turning point regarding new method for designing human space. While architecture discipline of the West focused on logic, Japan based its origin in eastern discipline has developed a unique design concept called 'metabolism' and advanced it very effectively. Since its development of the unique concept, Toyo Ito has become one of the most Influential architect in and out of Japan who devoted his design career in developing new space concept. This study is specifically focused on Ito's project by finding characteristics of his projects and analyze emotional design factors by using 5 analytical tool - experiencing the space, five senses, landmark, sequence, and scale. Ito's work between 2000-2004, such as Sendai Mediatheque, showed more visible sign of emotional design characteristics compared to the works done in 1990's. Because of the analytical studies researching those emotional design characteristics and methods, the future advancement in new space design will be possible with great success. The result proves that continuing proper analysis and research in design method will assist in approaching new space design method into more advanced realm in very efficient time period with more definite design elements to accomodate and fulfill human needs in given space.

Recently, the quantity of using information go on increasing geometric-progression. At the same time, the management of information is effected on the most organization's effective operation so that many user call for the powerful equipment which expound. access more information. As information searching technology is concentrated about the object of information based on a letter mainly, an effective searching technology for the object of multimedia such as a still image, a video and a sound must be studied. As a monitor of computer is 2-D, it difficult for one to grasp the whole aspect at a look glance like a library. Accordingly, some condition is necessary. First, it acquired the virtual video, turning a camera around by 30 degrees with a camera of 15mm lens, giving a warping and distortion. Second, it improved the books for user to search easily, adding to the video in existing books information system. The original text suggests some way which can embody the video searching technology under the base of personal computer.

In this paper, we design a non-volatile memory IP, 1-kb one-time programmable (OTP) memory, used for power management ICs. Since a conventional OTP cell uses an isolated NMOS transistor as an antifuse, there is an advantage of it big cell size with the BCD process. We use, therefore, a PMOS transistor as an antifuse in lieu of the isolated NMOS transistor and minimize the cell size by optimizing the size of a OTP cell transistor. And we add an ESD protection circuit to the OTP core circuit to prevent an arbitrary cell from being programmed by a high voltage between the terminals of the PMOS antifuse when the ESD test is done. Furthermore, we propose a method of turning on a PMOS pull-up transistor of high impedance to eliminate a gate coupling noise in reading a non-programmed cell. The layout size of the designed 1-kb PMOS-type antifuse OTP IP with Dongbu's $0.18{\mu}m$ BCD is $129.93{\times}452.26{\mu}m^2$.

This study is to investigate sleep patterns of rheumatoid arthritis patients through a survey research. The subjects for this study were 97 patients registered in Hanyang University Hospital Rheumatoid Arthritis Center, and the period of data collection was from July 15, 1998 to August 30, 1998. The research instruments used in this study were the measures of sleep, pain, and fatigue, and SPSSWIN 8.0 Program was used for data analysis. The research results are as follows ; The patients went to bed between 11 and 12 p.m., but many of them found difficulty in falling asleep within 5 minutes. They woke up quite early at around 4 to 6 o'clock in the morning and remained in bed about 1 hour. Only 39 percent of the subjects reported satisfaction with their sleep. Fifty six percent of the subjects took a nap, generally did in the afternoon and 22.7 percent of them napped for half an hour. They suffered sleep disturbance, but their sleep environments were calm and comfortable, and they turn off the light when they went to sleep. As for the quality of sleep, over 50 percent of the subjects reported not being able to sleep deeply, 30 percent of the subjects woke up frequently during sleep, 60 percent experienced frequent arousal after sleep onset. Over 90 subjects slept for 6 to 8 hours. This shows that even though they had rheumatoid arthritis, the patients remained in bed for a sufficient period of time. They also reported waking up or turning frequently during sleep. The sense of fatigue from sleep disturbance scored a relatively high 35.84 points on average against the possible score of 64 points. Behavior for sleep promotion was very active. Sleep disturbance occurred in proportion to the sense of fatigue and pain, and was negatively correlated with quality of sleep. The pain had positive correlations with the illness duration, sleep disturbance and had a negative correlation with the quality of sleep.

PURPOSES : This study evaluated the feasibility of implementing protected-permissive left-turn (PPLT) signals at three-leg signalized intersections. METHODS: A three-leg signalized intersection with permissive left-turn was first selected. A VISSIM simulation model was constructed using data collected from the test site. The VISSIM network was calibrated by adjusting related parameter values in order to minimize the difference between the simulated and surveyed critical gap. The calibrated network was validated by the number of waiting left-turning vehicles per cycle. Finally, the mobility and safety measures were extracted from simulation runs in which permissive, protected left turns as well as PPLTs were realized based on diverse traffic volume scenarios. RESULTS : The mobility-related measures of effectiveness (MOEs) of the case with PPLT outperformed the other two left-turn treatment scenarios. In particular, the average waiting time per cycle for the left-turn vehicles in the case with PPLT was reduced by 30 s. The safety-related MOEs of the case with PPLT were somewhat higher than those in the case with protected left-turns and much higher than those in the case with permissive left-turns. CONCLUSIONS : Based on the mobility- and safety-related MOEs generated from the VISSIM simulation runs, the use of PPLT seems to be feasible at three-leg signalized intersections where the left-turn is permissive and a pedestrian signal exists at the conflicting approach. However, in order to use the PPLT in earnest, it is necessary to revise the road traffic act, traffic signs, and related manuals.

To develop the composting system to reduce the use of bulking agent, continuous composting was performed with farmer scale facility, The plant comprises a horizontal pit reactor closed inside a greenhouse and equipped with a turning machine moving on rails. The pit was 9m wide and 50m long and the maximum height of loaded materials was $1.8m^2$. The materials remained in the reactor for 5 months. During the composting process, temperature and water content measured and water balance was evaluated. The reaction temperature of composting was changed $30{\sim}50^{\circ}C$ and high in the middle and low in under composting piles. The moisture contents of the compost were approximately 70% during the experiment. The amount of effluent was 10.6% and $3.16m^3$ of pig slurry per $1m^3$ of bulking agent was treated during continuous composting process. BOD and SS reduction of the effluent in continuous composting was 86.5% and 92.2%, respectively. Indoor relative humidity in night time was changed between 80 and 100%.

To develop Grifola frondosa as a new commercial product, we investigated the optimal primordium formation method for bottle cultivation. Primordium formation was initiated on the sixth day in all treatments, but in the T7 treatment, which consisted of removing old spawn and turning the bottle upside-down, was initiated on the ninth day. The ratio of primordium formation was at its highest value, 98.9%, in T3 and T7. Among the treatments, T7 produced the highest quality fruiting bodies and a mushroom yield of 112.8 g in each 850 mL bottle, but its crop cycle time was somewhat longer than those of the other treatments. These results indicate that appropriate methods for primordium formation in bottle culture could enhance mushroom quality and productivity.

The Liangshan pig is a traditional Chinese small-sized breed; it has a relatively long feeding period and low meat production ability but superior meat quality. This study utilized three non-linear growth models (Von Bertalanffy, Gompertz, and logistic) to fit the growth curve of Liangshan pigs from an unselected, random-bred pig population and estimate the pigs most suitable slaughter weight. The growth development data at 20 time points of 275 Liangshan pigs (from birth to 250 d) were collected. To analyze the relative gene expression related to development, seven slaughter weight phases (50, 58, 66, 74, 82, 90, and 98 kg) (20 pigs per phase) were examined. We found that the Liangshan pig growth curve fit the typical S-curve well and that their growth turning point was 193.4 days at a weight of 62.5 kg, according to the best fit Von Bertalanffy model based on the goodness of fit criteria. Furthermore, we estimated that the most suitable slaughter weight was 62.5 to 74.9 kg based on the growth curve and the relative expression levels of growth-related genes.

Fire-resistant boom is one of the most important facilities in in situ homing of spilled oil. Thermal response of a fire-resistant boom to turning is experimentally investigated in this paper by using an electric furnace and a burning test facility. This test facility is composed of a test tank, a fire boom, a hood for inhaling smoke, an incinerator for burning up gases and thermocouples, etc. Thereby a systematic method of approach in small laboratory scale is developed to study the performance of a fire-resistant boom. Burning test is carried out for the fire boom model which has been developed through the present study. It is shown that the present fire boom model has capability to withstand the high temperature around 800℃ and high rate of heat flux on it due to homing. For more realistic experimental environments, larger dimensions in devices and longer time in experiments are recommended in near future.

Recently, ship collision accidents account for $20\%\∼30\%$ of domestic marine accidents, also have increased continually. In this paper, therefore we propose the development of Ship Collision Avoidance Support program for decreasing ship collision accidents. This program has been developed on the basis of CCAS-Model. A CCAS-Model has ship's maneuvering performance and has studied for the propose of supporting to avoid ship collision in close quarters. Besides, the program will effectively support maneuvering for collision avoidance through displaying the feasible area and the method of collision avoidance using own ship's turning characteristic about action of target ship's keeping course and velocity in various encounter.
