Flexibility, love of symbols, small size-these are all qualites that accompany the proclivity towards compactness in Japanese culture. They developed and have been refined to an unusual level in Japan partly out of the necessity to use limited space economically, but these qualities also characterize the aesthetic preferences of the people. Because space is so precious, it receives a great deal of attention in every aspect of life. Over the centuries Japanese have devised innumerable ways to use space that are ingenious in their successful combination of pragmatism, harmony, and beauty. Folding, stacking, rolling, nesting, carrying, consolidating, miniaturizing and transforming are some of the techniques for living that have created the compact culture. Folding allows a one-dimensional object to be placed in prescribed small space. Stacking objects of the same shape makes use of vertical space, saving valuable horizontal space. Rolling an object reduces it to a tidy cylinder without creasing it, creating yet another form of repose for functionally flat things. Nesting several identically shaped objects of graduated sizes is known as ireko. Carrying things by hand makes them available for any occasion, by plan or on impulse. Consolidating is to bring together the multifarious systems of living into an integrated whole. Miniaturizing things is a way to bring even the universe down to the scale of a human hand. Transforming the face of things is another notable propensity in the Japanese life style. Each one is put to use in countless ways, suggesting principles and conceptions that encapsulate the wisdom of tradition. In this study I wishes to investigate the principals of Japanese traditional design and the applied case in fashion goods.

No matter how low it might be, noise from home appliances in indoor environment cause displeasure for residents as it is produced nearby. Electronic goods including vacuum cleaner and washing machine generate high frequency noise, which interrupts TV-watching or conversations and cause noises between floors in apartment houses. In particular, refrigerators make constant noise late at night, hampering the study for exams and causing sleeplessness. Korea, despite the government's efforts to promote low-noise goods based on the noise test by corporation, there is a lack of standardization in the test method, test condition and measuring equipments. This is a major reason that lowers the reliability of low-noise products. At present, low-noise home appliances are certified with eco labeling in the nation but, only 7 brands of refrigerators, 4 brands of washing machines and 97 brands of air-conditioners obtained certification as of august, 2011. In addition, none of Kimchi-refrigerator and vacuum cleaner brands were approved as low-noise home appliances. This shows Korea's relatively underdeveloped market for low-noise products, which, in part, is because of the difficulties companies face in being certified with eco labeling as they should satisfy various requirements such as power-saving and eco-friendly design besides low-noise features. As a result, low-noise labeling for home appliances should be established for the revised noise and vibration management law and the study was carried out to establish low-noise labeling system for major noise sources including vacuum cleaner, washing machine, air-conditioner and refrigerator.

The doma (cutting board) is an essential kitchen utensil. The general doma used at present is not sultable for cutting kimchi-like juicy foods, because It is a nat flat structure. Kimchi juice contains vitamins, organle acids, and lactic acid bacteria, and inhibits Oxidation of flavor of kimchi. In addition, if the juice flows down on the doma during cutting the doma work-table and kimchi bottom is contaminated. In this studies a new type of doma for kimchi. was made in order to minimize the Juice Iou during cutting. This new one baa a two-dimensional function of low due to length slope face and slanted gutter of width. No this new type has been developed worldwide, as far as the present writer is aware. The new one has various effectivenesses: minimixing loss of kimchi juice and contamination of doma work-table and kitchen bottom by kimchi juice, saving water and time to water contaminated cutting board, work-table and diahtowel (hangju). preventing round from falling down frorr doma duing cutting, decreasing damage of cutting the user's finger, cutting by the fixed size and shape. Draining and drying is easy and it is convenient to cut all juicy food.

IATA is playing a central role in the process of changing the international technical standards of common-use system which supports the airport check-in and boarding business in conjunction with the airline systems from CUTE to CUPPS. IATA expects that if the airport common-use system is changed to CUPPS, the development and maintenance costs related to the airline's common-use system can be reduced by the implementation of the standard interface about check-in and boarding business-related equipment and the certification of airline applications. Incheon International Airport is in the face of stiff competition with major Northeast Asian Airports to attract more airlines. To be more competitive than other airports, switching over to CUPPS is vital for airline's cost-saving effect. This study builds on CUPPS international technical standards and suggests design and implementation plans of Incheon International Airport's component-based next-generation common use passenger processing systems to support the various functions of user's requirements.

Traditional surgery to remove foreign bodies in the face carries a risk of postoperative morbidity with an injury to various anatomical structures, particularly the facial nerve and parotid duct and gland. Endoscopy can be a great aid in the removal of foreign bodies in the maxillofacial region. Surgical intervention using endoscope and/,or intraoperative images can be minimized, allowing the safe and precise removal of foreign bodies, and saving operating time. We report a case of the use of an endoscope and C-arm fluoroscopy guidance system to remove a very small foreign body.

This study is to investigate an optimal size and position of PV system for apartment complex through the electrical load matching analysis. The 4 types of arrangements of apartment buildings are considered as follows; ㅡtype, alternative ㅡtype, ㄱtype and ㅁtype. We assume that the studied site is composed of 9 buildings. Firstly, solar access evaluation of roof and facade in apartment buildings was performed with the hourly simulations of total received insolation on each surface considering the shading effect of buildings. Electrical load profile of typical Korean apartments were investigated for the load matching analysis. To calculate an annual total PV output, we used MERIT program which is a hourly based load matching tool developed by ESRD. TRY weather data of Daejeon are applied for this analysis. Result shows that approximately 11% of total electric load of the site can be supplied by the PV system in the case of full installation of PV system at the whole south-face roof area of 9 buildings in this stuided apartment complex. Depending on a various installation option of roof and facade area, the possible ratio of PV supply in total electrical load varies from 9% to 42%. Among the 4 arrangement types, the ㅡtype revealed the best option for the maximum output of PV system.

Silver nanoparticles have been widely applied for biomedical areas owing to their potent antiviral and antibacterial activities. Synthesis of silver nanoparticles using biomacromolecules is more efficient, environment-friendly, and cost-saving compared with the traditional approach. In this paper, a novel approach was developed to establish a reaction system with $Ag^+-BH4^--sericin$ to synthesize silver nanoparticles conjugated to sericin (AgNPs-Sericin). Sericin could be as a good dispersant and stabilizing agent, which is able to modify nanoscaled AgNPs, the average diameter of which was only $3.78{\pm}1.14nm$ prepared in a 0.3 mg/ml sericin solution. The characterizations of the AgNPs-Sericin were determined by FTIR, thermogravimetry, and XRD analyses. The results showed that the synthesized AgNPs conjugated with sericin as organic phase. Via SAED and XRD analysis, we showed that these AgNPs formed polycrystalline powder with a face-centered cubic structure of bulk metals. Moreover, we investigated the antiviral and antibacterial activities of AgNPs-Sericin, and the results showed that AgNPs-Sericin exhibited potent anti-HIV-1 activity against CCR5-tropic and CXCR4-tropic strains, but no significant cytotoxicity was found toward human genital epithelial cells compared with free silver ions, which are accepted as a commonly used potent antimicrobial agent. Moreover, its antibacterial activity was determined via flow cytometry. The results showed that AgNPs-Sericin could suppress gram-negative (E. coli) and gram-positive (S. aureus) bacteria, but more was potent for the gram-negative one. We concluded that our AgNPs-Sericin could be a potential candidate as a microbicide or antimicrobial agent to prevent sexually transmitted infections.

With the advances in the information technology and mobile communications, we now face increasing demands for various services based on both of position tracking of moving objects and their efficient index scheme. Accordingly, the $TPR^*$-tree, which were proposed for efficiently tracking moving objects and predicting their positions in the future time, has drawn much intention. As the $TPR^*$-tree came from the R-tree that is suitable for indexing static objects, it does not support cheap update costs. Therefore, it seems to be very costly to index moving objects if there are frequent occurrences of node updates caused by continuously changing velocities and positions. If some moving objects with high velocities have node updates, in particular, then the $TPR^*$-tree may suffer from many unnecessary updates in the wide range of tree regions. To avoid such a problem, we propose a method that can keep fast-moving objects in the child nodes of the root node, thereby saving node update costs in the $TPR^*$-tree. To show our performance advantages and retaining $TPR^*$-tree features, we performed some performance experiments using a simulation technique.

Recently, in order to realization of construction and economical saving, various studies are progressing. Also, the study on RCS system which is consisted of reinforced concrete column and steel beam is progressing actively. Actually, however, resisting mechanism of panel zone is influenced by transverse beams when the stress transfers inner panel to outer panel but existing literature didn't reflect the effect of transverse beams. This paper is to analyze the test result of five inner beam-column joints specimen with a variable such as web, flange thickness of transverse beam and face bearing plate(FBP) for RCS systems were tested under cyclic loadings conforming to NEHRP recommendation to investigate the effect of transverse beams and the structural performance of beam-column joints. From the test result, it was shown that transverse beams are effective to enhance the shear strength and structural performance of beam-column joints.
