Using password on system is easy to build and shorten the access time to authorize user, which is high in use for vary system that requires users' authorization. Many input device are able to perform the password system easily, such as PC, smart-phone, tablet PC, etc. Beside the high usability of password, physical attack occurs when user put their password on the device, known as Shoulder Surfing attack. It used to be formed in numbers, characters or mix of different kinds, but new kind of password arose. Exploiting image or making scenarios are those kinds which are able to reflect users' intentions. Not many estimation exists for new password, so there's need to be standard for those new password for highlighting usability and accessability. In this paper, we propose password system with simple image and switching key-board to test statistical method to estimate usability on the password.

The movie, X-men, develops the narrative with metamorphosis as the main motif making visual effects of characters and background. The objective of this study is to suggest that the metamorphosis motif can be materialized based on the virtuality of "pataphysics" as one of the genre characteristics of superhero movies and the newly materialized virtuality can be aesthetic characteristics of metamorphosis motif movies. With the virtuality that has its own characteristics with metaphorical symbols such as satire on an absurd society out of existing traditions, pataphysics started in mid-twentieth century and has had an impact on art movements of dadaism, surrealism, pop art, and postmodernism. Analyzing the characteristics of pataphysics which were shown in these artworks, we applied it to metamorphosis scenes of the movie. As a result, we found out that it visualized the shape and aspect of inner and outer strength of a superhero with aesthetic characteristics of metamorphosis scenes and it realized the presence, hybridity, and ex-formal properties of pataphysics consisting of overlapped virtual and physical reality, with technical virtuality.

The type of trichomes, their density and pattern of distribution on leaves of 16 genotypes of mulberry, belonging to both diploid and polyploid categories, were studied by scanning electron microscope. The present investigation was undertaken to find out the relationship of physical attributes, especially the density and trichome types with higher acceptability and better rearing performance by the silkworm Bombyx-mori L. Two types of trichomes glandular and non-glandular types were observed on both the leaf surfaces of all the mulberry genotypes studied. In general, greater densities of trichomes were observed on the abaxial surface than the adaxial surface of leaves in most of the genotypes. Distribution of glandular trichomes were more in abaxial surface and non-glandular trichomes were more in adaxial surface. Overall, distribution of glandular and non-glandular trichomes per unit area of leaf did not follow any regular pattern. When leaves of those genotypes were fed to silkworms, trichome density was found to be significantly negatively correlated with the survival of larvae i.e., effective rate of rearing, but trichome density did not influence the economic characters of rearing. As the distribution of glandular trichomes (GT) and non-glandular trichomes (NGT) did not follow any definite pattern, no relation could be established between the GT and NGT densities with silkworm rearing performance. However, the ratio of GT and NGT in a particular genotype influenced the rearing parameters, higher the ratios better the rearing performance. High GT and NGT ratio (＞1.00) was found positively significant when correlated with economic parameters viz., larval weight, single cocoon weight and single shell weight. The study is useful in screening different mulberry genotypes for their better acceptability to silk-worm and higher rearing performance at the early stage of selection without actually conducting the rearing.

Objectives : The objective of this review is to introduce the basic concepts on the febrile disease in the Mongolian Traditional Medicine(MTM). Methods : We comprehensively reviewed related textbooks in Mongolian and articles searched from China National Knowledge Infrastructure(CNKI) on febrile disease about MTM and summarized the pathophysiologic basis of, and treatment principles in MTM. Results and Conclusions : 1. In MTM, there are basic concepts such as theory of Arga-Bilig, theory of five elements, theory of three elements(人體三素), theory of seven constitutions and three discharges(七元三濊). Most of all, theory of three elements, which is about the basic elements of human body in MTM, is important fundamental notions for explaining human physiology and pathology. In MTM, It is explained that the imbalance of three elements, namely khii, shar, bad-kan is the root of all disease. Especially, febrile disease is treated by suppressing activated shar and blood(血液), which have fire characters, and managing various additional symptoms by balancing three elements and eliminating miasma(邪氣), inappropriate substances such as bile water(shar yc, 黃水) or blood stasis(惡血) simultaneously. 2. In MTM, both of internal treatment modalities(various medicinal therapy) and external treatment modalities(physical therapy) have been used for febrile disease. Food therapy and life style modification also have been recognized as important treatment methods. These aspects correspond to wholism theory of Korean Traditional Medicine(KTM). Further studies about details of each treatment methods will discover new applicable treatment method and make broaden the external boundaries of the KTM.

The existing market patterns and social structures have been changed according to the trends of digital and informational society of the 21st century. The characteristics of the consumption market is that the balance of power moves from enterprises to consumers. As consumers’ demands are diversified according to life quality enhancement, many products are based on main aspects of human experiences, emotions and values. Standardized functions and services of products cannot capture consumers to a great extent any more. A notable aspect is that consumers want products or services that can oner movable experiences. Future products must appeal to emotion, not to reason of consumers. Now consumers purchase styles, experiences and stories contained in products, not products themselves. That is, the key to decision to purchase products is the satisfaction of emotional values. Users'emotions diversified due to the development of industrial designs demand the development of new designs that can represent new trends of users. User-centered values imply the change of people's purchasing trends. This indicates that there is a need to change physical aspects such as price or functions into individual emotions and characters. In addition, studies are required on design concepts to pursue new emotional values, apart from functional type designs. It is time for designers to suggest initiative and rational directions for this changing era.

The rice quality related traits including physico-chemical traits were evaluated with one hundred sixty-four MG RILs derived from the cross between Milyang 23, Indica/Japonica hybrid type, and Gihobyeo, Japonica type. The variation distribution of all traits examined approximately fit normal distribution and transgressive segregants over parents were observed for all traits. The occurrence of such transgression could be associated with the interactions of complementary QTL alleles from two parents. However in this study, it could not be concluded that our results of segregation were due to either complementary gene effects or overdominance of a major gene. These factors should be verified by further studies. Correlations between traits were evaluated by regressing phenotypic values of one trait on those of another traits. There are highly significant correlation between grain thickness with grain width, white core and white belly. But between white belly and alkali digestion value showed highly negative significant correlation. Contents of protein showed highly negative correlation with amylose and Mg/K ratio but showed highly correlation with K and Fat contents. Hardness of cooked rice showed highly correlation with adhesiveness, elasticity, gumminess, chewiness.

This treatise was carried out to study the hereditary phenomenon of silk lousiness and the interaction of genes related with silk lousiness. It was also studied how to improve the silk lousiness of general raw silk by refining process because the selective process was found as unsatisfactory method. The conclusions reached were as follows. A. Conclusions related with genetic problem. 1. The decreased effects of the lousiness were 11 % in the F$_1$ hybrids. 2. Lousiness was considered to inherit as the incomplete dominance. 3. The effects of the lousiness gene were additive, and the lousiness of raw silk might be influenced by more than two genes. 4. The quantitative characters of cocoons were not genetically correlated with the occurrence of lousiness. 5. Lousiness could not be said to occur more in the heavy-cocoon strains. 6. The microscopic lousiness test of this paper showed the same result of the international exforiation test. B. Conclusions related with lousiness improvement. 1. Raw silk was able to be refined by the employment of 0.2% cationic softener solution for 30 minutes at 95$^{\circ}C$, supressing the occurrence of lousiness. 2. Anionic chemical softener was not available for silk refining process. 3. The above cationic softener refining prosess did not cause any physical defect for the silk fiber. 4. Soap refining process caused silk lousiness easily.

The TUI system Modeling Language(TML) developed in this research can be used for designing TUI system with concerning about TUI's characters. For design to be concerned about physical property of tangibles and control device and digital media, TML can be a framework to give a definition of each property and be used for designing action and reaction process separately. And it would be the guideline to represent interaction's dynamic property through showing parallel information flows among objects. Finally, for verification TML's suitability, TUI system to which TML was applied was developed.

In the virtual space with the interactive 3D contents, the degree of mental satisfaction is determined by how fully it reflect the real world. There are a few factors for getting the high completeness of virtual space. The first is the modeling technique with high-polygons and high-resolution textures which can heighten an visual effect. The second is the functionality. It is about how realistic represents dynamic actions between the virtual space and the user or the system. Although the studies on the techniques for animating and controlling the virtual characters have been continued, there are problems such that the long production time, the high cost, and the animation without expected behaviors. This paper suggest a method of behavior control of animation by designing the optimized skeleton which produces the movement of character and applying the procedural technique using physical law and mathematical analysis. The proposed method is free from the constraint on one-to-one correspondence rules, and reduce the production time by controlling the simple parameters, and to increase the degree of visual satisfaction.

As the number of children's libraries has increased in Korea, it has been discussed to improve the quality of design in the libraries. In a reading room of children's library, spatial consideration should be focused on the children under 10 years old since they are in important points to learn Hangul and to develop reading habits. This study is aimed to examine the characteristics of a floor-sitting reading room, where children can feel like a home, stay in clean and safe and play while reading. The seven case studies of floor-sitting reading rooms are analyzed from the viewpoint of each factor of physical environment, including structure, furniture, and decoration. The following is the summary of findings of this study. First, floor-sitting reading rooms tend to compose main reading areas around bookshelves. Reading areas create the characters by changing floor levels and arranging furniture associated with windows, columns, and wall-type bookshelves. In the reading areas, movable low-level tables are frequently placed for flexible space uses, and seats for reading tend to put together with fixed bookshelves. Second, the central areas of the reading rooms are often shaped in the forms of pods, storytelling areas, sculptures, and unique furniture. Especially storytelling areas and pods play the cores of the reading rooms with the varying steps of floors and pictorial graphics on walls. Third, decoration elements in the reading rooms are designed with graphics, visual displays, and sculptural decorations. In my case studies, spatial elements such as reading nooks, attics, tunnels, and shelters are not often found in the floor-sitting reading rooms even though children like to have them. Since it is the advantage of floor-sitting reading rooms where children can take off shoes and act freely, we should look for the design of such spatial elements in the floor-sitting reading rooms.
