OP-Art was not appreciated by painters and art critics. and according1y has been forgotten in art history. But recently Op-Art is revitalized in fashion and is in its palmy days. This study intends to re-assess the value of Op-Art, by reviewing its influence on fashion design in the post-modern society To this purpose, conceptual characteristics of Op-Art was analyzed. And then, on the bases of these characteristics, the figural characteristics and the meaning of Op-Art in fashion design of post-modern society was re-explained. Op-Art is characterized as an art of flatness of picture plane which uses repetition of simple forms and colors. It is also based on trick of visual perception. Finally. it creates an impression which is flickering or vibrating by means of optical illusion. These characteristics give birth to some features such as simplicity. anonymity and mobility in the Op-Art fashion. The meanings of Op-Art in fashion design in post-modern society are as follows. First, repetition of simple units employed in Op-Art produces feeling of simplicity. which makes the Op-Art fashion works perceived as polysemy. In other words, the feeling of simplicity can be interpreted In diverse perspectives within the social context of our society. The material civilization and technology civilization, which causes the alienation and standardization of man. can be the backgrounds of the Op-Art fashion. Second, Op-Art is an art based on perspectives of spectators. Anonymity in the Op-Art fashion enhances participation of spectators. which gives Op-Art a sense of affinity. Third, through the feeling of mobility created by optical illusion techniques. the Op-Art fashion expresses the opposition to the ideal body image made by power group. In post-modern society, Op-Art in fashion gives new meaning to art. Op-Art in fashion proposes new roles of artist and spectators, and new concepts of art related with roles of human beings. Through general sensibility of men, Op-art in fashion can express new recognition of the post-modern society.

Place memory is a new way of seeing as a new concept of cultural landscape research. Various research works and discussions have recently spread in landscape studies. In particular, the, which is visible and material, is a medium in which collective memory is embedded in place memory. The purpose of this study is to extract places of memory from the collective memory of residents of Janghang, Korea, and to visualize it through semantic relations. For this purpose, semi-standardized interviews (34 persons) were conducted with residents, and frequency analysis and semantic network analysis were used. As a result, the interviewees recalled only 127 places in Janghang that existed between 1920 and 2010. Locals remember the city based on places of memory. This means that the city could be illustrated according to specific places that are frequently mentioned. For instance, the top 25 places (top 20%) explain 65.6% of all the places in the city, and the top 39 places (top 30.8%) could describe 78.7% of the places. Some places are referred to more frequently when they are in the city's symbolic landscape, and the city's identity is projected on them. Some places were mentioned only infrequently but were nevertheless very important places by which to understand Janghang. These places of memory have not appeared in the documentary records before, which shows the value of the collective memory of the locals and the effectiveness of the interviewing method. In the clustering of the semantic network, six groups of places appeared. The local residents remembered the modern industrial city and recalled it in connection with the sites of daily life. This shows the possibility of looking not only at public memory and famous heritage as a macro history but also at daily life and meaningful places as a micro history about locals. This study has significance as an initial research that identified and visualized places of memory from the perspective of local residents. Such an approach could be useful in the study of everyday life and the conservation of modern heritage.

The purpose of this research was to re-illuminated the artistic value of costumes that had shared identical history with human beings through the formation and the progress of the newly introduced Russian avant-garde an. This resulted from the fact that the Russian avant-garde art changed the human esthetic sense through the style of art that Larionov and Goncharova introduced in the 20th century. The research method defined the formation and the progress of the development of the Rayonism centering the works of art by Larionov and Goncharova. Based on this method, larionov and Goncharova designed the set and the costumes for the Ballets Russes of Serge Diaghilev and studied the molding characteristics of the costumes worn in the performing an. The result were as follows. First of all, Larionov's costumes of art were all manufactured based on the theme of nature and genesis. In other words, Larionov represented the sun as a humanistic god through the white night, the natural weather condition of northern Russia. His costumes also displayed the symbolic meaning of the personification of animals like birds and cats, which emphasized the importance of both nature and tradition. However, he used Rayonism expression when he designed costumes by applying the nature themes. On the other hand, Goncharova applied the Spanish passion, the Russian folk art lubok, and goldern cockerel or religious icon-paintings in her costumes. she pursued straight lines and abstract shapes in her costume design. her design displayed the Rayonism influence through the separation between the lines and the surfaces, whic defined the costumes as a decorative art experiment. Therefore, the study of Larionov and Goncharova had one realize that Rayonism was not only an art form of Avant-garde, but it also became the basis of the molding character of all the artworks. Larionov and Goncharova reflected the miracle of the transformation of the 20th century in their costume designs.

Practical experience with technology implementation of the upgrading of very small village industries in India suggests that innovation failures are not merely a result of the lack of proper interaction between the users and suppliers of technologies under implementation, but also a result of adoption of the primitive conception of competitiveness in their practice of technology development. The approach of promoting the small producers to become individually competitive by using labour intensive, small-scale intermediate technologies is proving to be totally inadequate for the achievement of technological efficiency in a dynamic sense. Guided by a primitive notion of competitiveness, the suppliers of intermediated technologies are thus being led into limiting their technological efforts in the sectors of direct interest to the rural industrial clusters to the transitional objectives of mainly poverty alleviation. Consequently they have not been able to target the small producers of these village industries for the objectives of business growth. This paper posits that under competitive conditions the self-employed small producer has not only to come together for access to resources, but also has to emerge as a multi-sectoral collective of producers, co-operating in production. With the aim to draw lessons that are generic and have policy implications for the development of innovation systems for local economy based rural industrial clusters and value chains, the author analyses in this paper the experience of innovation in technological systems for the sectors of leather, fruits and vegetable processing and agro processing by the People's Science Movement with the help of the Ministry of Science and Technology and other sectoral ministries in India where rural poor were required to pool the resources and capabilities for raising the scale and scope of their collective production organization.

The National Foundation Day of Korea (개천절, 開天節) is currently celebrated on October 3 in Gregorian calendar. We review the history of dating the National Foundation Day of Korea and make a suggestion that it be celebrated on October 3 in the lunar calendar. We present numerous historical records on heaven-worship rites supporting the date October 3 in the lunar calendar. It is pointed out that October 3 in the solar calendar has been adopted in 1949 by the National Assembly with the thought that the lunar calendar is inferior and behind the times. The thought originates from misunderstanding on the value of the lunar calendar and from the ignorance of importance of history and tradition. Since there are now many national holidays that follow the lunar calendar, the logic of the National Assembly in 1949 also makes no sense. We emphasize that the lunar calendar should be followed for the National Foundation Day of Korea for its historical and symbolic characteristics restoration. We also investigate the year of the foundation of the first country of Korea, Dangun Joseon. It is found that even though the majority of the literature before late 15th century recorded the beginning year of Dangun Joseon dynasty to be equal to that of Liao Dynasty (堯), it was accidentally changed to the 25th year of Liao Dynasty in 1484 through a misinterpretation of the previous records. We claim that the beginning year of Dangun Joseon should be set to that of Liao Dynasty as recorded in the original literature in the earlier days. According to the two main opinions accepted by Korea, the beginning year of Liao Dynasty was 2357 B.C. or 2333 B.C., which correspond to the year of Gap-Jin (the 41st year of the sexagenary cycle) or Mu-Jin (the 4th year of the sexagenary cycle), respectively.

This study is aimed to investigate ethics cognition to information of youths who are main users of computers, but yet not built up the own ethics and the sense of value, as ethical problems are raised in information-oriented society. The research was focused on youths ethics cognition to information according to contact of multimedia pornography, surreptitious use of others and abusion of indecent languages in chatting. The survey was conducted to 520 students from middle and high schools in Jeju region and analyzed Probit Regression. The major results of this study are as follows; First, most of youths possess own-computers, and use Internet. Second, looking into experiencing or not according to sub-spheres of ethics cognition to information, the experience of contacting multimedia pornography was few. but the primary place of using it was a house. Most of youths approach multimedia pornography in awareness of a ban on youths' contact. The experience of surreptitious use of others was less than other spheres, and mainly only once. The number of youths who have an experience of abusing indecent languages was less than that of youths who don't have, but the frequency of was high when the youths have an experience. Third, the experience or no experience on each sub-sphere has a significant difference on personal-relative variables such as gender, age, education levels, number of siblings, academic records, personal expenses, relationship with friends. The experience or no experience on each sub-sphere has a meaningful influence upon family-relative variables such as father's education levels, Job, mother's age, education levels, employment, family type, monthly household expense. The experience or no experience on each sub-sphere has a meaningful influence upon PC-relative variables such as deviation experience in PC rooms, the experience of request for age confirmation(I.D. card), average use hour of PC rooms. The experience or no experience on each sub-sphere has a more meaningful influence on personal-relative variables and PC-relative variables than family-relative variables.

In the water purification plant, chemicals are injected for quick purification of raw water. It is clear that the amount of chemicals intrinsically depends on water quality such as turbidity, temperature, pH and alkalinity. However, the process of chemical reaction to improve water quality (e.g., turbidity) by chemicals is not yet fully clarified nor quantified. The feedback signal in the process of coagulant dosage, which should be measured (through the sensor of the plant) to compute the appropriate amount of chemicals, is also not available. Most traditional methods focus on judging the conditions of purifying reaction and determine the amounts of chemicals through manual operation of field experts using Jar-test data. In this paper, a systematic control strategy is proposed to derive the optimum dosage of coagulant, PAC(Polymerized Aluminium Chloride), using Jar-test results. A neural network model is developed for coagulant dosing and purifying process by means of six input variables (turbidity, temperature, pH, alkalinity of raw water, PAC feed rate, turbidity in flocculation) and one output variable, while considering the relationships to the reaction of coagulation and flocculation. The model is utilized to derive the optimum coagulant dosage (in the sense of minimizing turbidity of water in flocculator). The ability of the proposed control scheme validated through the field test has proved to be of considerable practical value.

When Flat Panel Display (FPD) is made with backlight module, such as LED TV, it inherently suffers from the non-uniform backlight luminance problem that results in un-even brightness distribution throughout the TV screen. If the luminance of each pixel location of a TV screen as a function of the driving voltage can be measured, it can be used to compensate the non-uniformity of the backlight module. We use a carefully calibrated imaging system to take pictures of a TV screen at different levels of brightness and generate the compensation functions for the driving circuitry to correct the luminance level at each pixel location. Making use of the fact that the luminance of the screen is normally brightest at around the center of the screen and gradually decreases toward the border of the screen, the luminance of the whole TV screen is approximated by a mathematical function of the pixel locations. The parameters of the function are computed in the least square sense by the values of both the pixel luminance sent from the driving circuit and the grayscale value measured from the image taken by the imaging system. To justify the correction system, a simple second order polynomial function is used to approximate the luminance across the screen. When the driving circuit voltage is corrected according to the measured function, the variance of the screen luminance is reduced to one tenth of the one measured from the un-corrected TV screen.

The purpose of this study is to observe the elements of Japanese popular culture portrayed in Korean new generation fashion at the current point of time, when Japanese popular culture is first being opened to Korea. And the another purpose is to look into the fashion consciousness of them, which is made up of these aspects. The new generation plays the leading role in further excelling the culture of our society. They are the generation of sense and sensibility, the generation of "me", the generation of information, and the generation of individuality. Even before Japanese popular culture was officially opened, the new generation was already accepting fashion, comics and animation, video games, music, broadcasting, food, etc. The Japanese cultural elements that show most in Korean fashion are street fashion and the fashion of celebrities. These are mostly brought in by fashion magazines, the internet, satellite TV, the new media of cable TV, and street shops. The aspects of Japanese popular culture in Korean new generation fashion are many and varied. Such examples in fashion are : vintage style, school-girl style, sexy causal style, black coordination, soft avant-garde style. It can be said that the fashion consciousness of Korean new generation could be placed in the following order. First, the variety of fashion. Next, the internationalism of fashion. Third, the information of fashion, and last, the play value of fashion. Interest has peaked in Japanese culture after the official opening, and this study has explored the very same aspects which can be seen in Korean new generation fashion. This study was meant to help make a responsible and sturdy new generation fashion culture which can help face the new millennium.

Purpose - The purpose of this study is to analyze the user requirements and developer requirements in virtual reality(VR), and suggest ways to increase the satisfaction of users who experience virtual reality. Specifically, focused on experience store of VR as a distribution retailer, user requirements were analyzed according to the results of previous research that the characteristics of Affordance, Presence, and Head Mounted Display (HMD) affect user satisfaction. Research, design, data, and methodology - Based on previous studies, in this study, we analyzed the importance of immerse, interaction, perception, and presence for the satisfaction of the user through the questionnaire, and the user experiences virtual reality (VR) The importance of HMD, Presence, Affordance, and experience satisfaction were analyzed. Based on this, we analyzed the user requirements and the developer requirements based on the questionnaires and interviews of the experts, starting from the user's desire or preference using QFD technique. Results - As a result of the analysis, the development factors that occupied a big part in the virtual reality field appeared to be visual. In detail, this showed that there was a lack of sense of presence for users. This should be improved. This paper shows that the requirements for visual, auditory, and tactile development are necessary. For the satisfaction of the users of virtual reality (VR) users, it is necessary to develop them according to their priority in consideration of importance and difficulty in the future. Conclusions - In this study, it was suggested that development according to priority should be considered, considering the difficulty level. Based on the results of this study, the following suggestions are made. First, we tried to search the list of user requirements as much as possible, but it is likely to change due to the development of VR technology. Therefore, it is necessary for developers to continually supplement user requirements with recent research literature. Second, development priorities according to difficulty level should be considered. This aspect should be considered in the actual VR development process, so if the numerical value of the difficulty is calculated, it should be presented in the research.
