To investigate whether aqueous extract from Aconitum koreanum (AEAK) effects in the process of melanin synthesis, the expression of tyrosinase-related proteins (TRPs) by immunohistochemical methods were performed in ultraviolet B (UVB) irradiated skin of guinea pig. The irradiation of UVB (60 mJ/day) was performed for 3 days and treated with AEAK for 15 days. About the color evaluation, the visual scores of UV B irradiated guinea pig with AEAK treatment were slightly lower than those in the UV B alone irradiated ones. At day 15 after UVB exposure, immunohistochemical analysis for TRPs expression were performed. The intensive expression of tyrosinase was mainly observed over epidermis with skin appendage and in the cells of dermis. Slight increase of these reaction was induced in response to UVB in the spinous and granular layer of epidermis, but similar expression in the AEAK treated guinea pig as normal one. The TRP-1 and TRP-2 expression were not detected in the skin of normal guinea pig. But intensive expression for TRP-1 and TRP-2, especially TRP-2, induced by UV B irradiation in the cells of dermis. These expressions were decreased in the AEAK treated guniea pig. Collectively, these results suggest that AEAK has a potential to inhibit synthesis through regulation of TRPs expression in the skin of guinea pig, but better understanding the function of AEAK, more research should be done in the effects of AEAK on the function of TRPs in melanogesis.

Unexpected equipment defects can cause a huge economic losses in the society at large. Although condition monitoring can provide solutions, the signal processing algorithms must be developed to predict mechanical failures using data acquired from various sensors attached to the equipment. The signal processing algorithms used in a condition monitoring requires high computing efficiency and resolution. To improve condition monitoring on a wireless sensor network(WSN), data visualization can maximize the expressions of the data characteristics. Thus, this paper proposes the extraction of visual feature from temperature data over time using condition monitoring based on a WSN to identify environmental conditions of equipment in a large-scale infrastructure. Our results show that time-frequency analysis can visually track temperature changes over time and extract the characteristics of temperature data changes.

The purpose of this study is in allowing thinking about the design development process which is more towards the visual and perceptional aspects related to the form structure by more diverse methods by typology of idea generation. To accomplish such goal, researches in the psychology, pedagogy, engineering, and consilient studies as well as related precedent researches and reference data in architecture, promotion, industrial design, and other art fields and fashion designs are collected and analyzed to see the study trend. In addition, in the content analysis method based on such, the idea generation was classified into types in consideration of relevancy, usefulness, and suitability with fashion. First, a concentrated thinking of a limited space is a method of leading an optimal design by focusing on solving the cause of a problem within a space which generates the problem. Second, plan thinking per section of structure decomposition is a method of dismantling the design problems per organization, thinking type, factor, and characteristic into sub-modules to re-interpret and re-organize the problems in various aspects. Third, an associated thinking through interpreting relationships among vocabularies is a method of selecting the marginal languages that allow a person to come up with concrete forms and the key words related to fashion to import the characteristics and attributes of the marginal languages and thematic relationship between the two terms to search the relevancy. Lastly, the free integrated thinking of language extension is a method of groping integration between other fields and fashion by free integration among the extended terms by extending the vocabularies through inferring metaphorical expressions founded upon individual's memories or knowledge concepts regarding theme words that do not allow concrete forms to come up.

The role of sound in producing 3D animation clip is one of the important factor to maximize the immersive effects of the scene. Especially interaction between video and sound makes the scene expressions more apparent, which is diversely applied in video production. One of these interaction techniques, the out-focussing technique is frequently used in both real video and 3D animation field. But in 3D animation, out-focussing is not easily implemented as in music videos or explosion scenes in real video shots. This paper analyzes the sound data to synchronize the depth of field with it. The novel out-focussing technique is proposed, where the object's field of depth is controlled by beat rhythm in the sound data.

In order to deeply understand the significance of death aesthetics in contemporary art, this research first summarizes the development process of death aesthetics in art works with popular perspectives, and then classifies and discusses death aesthetics in modern art works. The results of this study are as follows: First, the aesthetic expressions of death are divided into two types: death reproducibility and death symbolism. Death reproducibility includes reproducibility of real objects and reproducibility of imaginary objects. The symbolism of death can be divided into external and internal manifestations. Secondly, in contemporary art, the reproducibility of death through the description of death scenes has increased the various problems and philosophical significance caused by death. Third, in contemporary art, the symbolism meaning of death is not just something directly related to death, it also shows the various psychological states brought about by death. Subsequent research will promote the artists' visual expression of the aesthetics of death in artworks, and the profound changes in meaning that result from it.

In this paper, we tried to find out what is the cinematographic reality conceived by André Bazin. To this end, we examined the process of his long exploration of realism, focusing on his film criticism. Through this, we read his deep concern that the film medium, which is more imitative than any other medium, would not become artistic but rather stimulating mimicry. When photographs or movies first appear, people have been interested in saving money by simply storing scenes in front of them or imitating stimulating scenes before realizing their artistic value. In this way, Bazin warned us that when the cheap pleasure derived from the simple imitation of fact is concatenated with the logic of capitalism, the film falls into a subordinate medium and drops the value of human beings indescribably. He therefore argues that cinema must transcend simple imitative dimensions by exploiting various abstract expressions in its own language. His works about the realism in cinema is meaningful in that the value of true realism of the movie is important to build up humanism today in respect that the movie raises extensively the logic of capitalism through visual pleasure.

It is obvious that the characteristics of the media are related with the visual expression found in film and video shots. It can be assumed that there would be unavoidable distortion when the space and objects are being framed into an image by the camera and that unavoidable distortion can be utilized for creative expression. Therefore the relationship among the shape of filming zone, the structure of the image, and the strategies of disposition of camera, actors, and objects were studied in accordance with expressional attempts found in film and video images. The classified cases of the expressions found in film and video was studied from the view of the dispositions and movements of the physical elements such as camera, actors, and objects which made the designated expression possible. Finally the organization of method to arrange of the elements used for film within film zone was resulted as the expressional directing methods for filming. Later the usefulness of the method was tested by the application of the method in educational procedure and the evaluation of the analysis of the students' results.

Poems written on the tablets hanging in Kwanghanru(a pavilion in Namwon, Jeollabuk-do) reveal each author's view of landscape and their recognition of the pavilion and it surroundings. This study consists of the following four analysis frames of the characteristics, sensations, and temporal and spatial axes of the landscape elements grouping tablet poems into two categories of deunglusi of Joseon's literary men, and baegiljangsi and cheongtaksi of the 1930s. The result of the landscape element analysis shows that physical elements are shown more frequently than symbolic ones. Among the physical ones, natural elements are used more often than artificial ones. The landscape elements appearing in each individual poem of baegiljangsi and cheongtaksi are relatively more than those of deunglusi. When the landscape elements are analyzed by sensational aspect, most of them are visual in nature, and there also appear some that are aural or olfactory in nature. Analyzed from a temporal axis, expressions related to autumn and evening and night are used frequently. From the spatial axis, foreground elements are preferred to middleground or background ones.

The purpose of this study is to attempt to diversify artistic expression through combinations of the twelve zodiac animals and origami techniques and to propose new directions for fashion design by applying these to fashion accessory bag designs. For the research method, this study researched the representative forms and characteristics of twelve zodiac animals based on the cultural background. Also, diverse cases of origami techniques were sought to apply them to the development of bags. The results are as follows. First, expressed forms of the Chinese zodiac were newly expanded by realizing the form of Chinese zodiac animals through various origami techniques. Origami work displays abstract visual effects rather than intuitive feelings or expressions of flat designs. With this, detailed realizations could be made through the characteristics and cultural implications of animals. Second, the work created in this study utilized zero-waste patterns that use origami techniques on one whole piece. During pattern production, folded parts were marked without waste and the outer fabric and lining were produced. Patterns were all symmetrical lines so most forms were expressed with squares and equilateral triangles. Third, through actual work produced using fabric instead of paper, effects that are brought about through folding are determined in diverse ways according to fabric textures or material types and thicknesses. When paper is folded, shapes are created as folded, but fabric requires the use of supportive material to create the effects of origami. Polyester and blended fabric were easy to use with high levels of function and practicality. Through such diverse production attempts, fixing methods, hand sewing, sewing machines, double-sided tape, and leather adhesive were used.
