The information technology intensive society rapidly moves from manufacturing industry to information technology industry. This paradigm of Robot is depending on intelligent Robot instead of labor. The conventional Robot worked through environmental variation and shift of job. This Robot is unactively response to men's mandate. And, this Robot have had iterative jobs through manipulation of men. But, this intelligent Robot have new technology through society paradigm shift. The outstanding feature of this Robot is perception function and cognition, mobility and manipulation. The definition of original Robot means forceful and tedious, slavery job. This is from robota, robotnick of the Czech Republic. Karel Capek, a playwriter of the Czech Republic use of this letter at 'Rossum's Universal Robots'. Conclusionally, the Chungbuk province is connected with Korea Institute for Robot Industry Advancement of Daegu and Sejong City. This affect mutual growth with local industry and advancement of environment about living life in the Chungbuk.

Use case modeling on UML (Unified Modeling Language) is getting widely used in OOAD and CBD and it is considered a useful technique in dealing with the complexity of the requirements analysis. However, some of the problems with use case modeling are that it is not structured, difficult to handle non-functional requirements, and to analyze impacts among use cases. To alleviate these problems, we propose a scenario-based goal-oriented approach for use case modeling. The proposed approach is to apply a goal-oriented analysis method to use case modeling. Since goal-oriented analysis method is not systematic and many heuristics are involved, we have adopted scenarios as the basis for goal extraction. The proposed method is applied to CBIS (City Bus Information Subsystem) in ITS (Intelligent Transportation System) domain. The proposed approach helps software engineers to analyze the impact among use cases and represent non-functional requirements.

This study was conducted to provide exportation strategy by surveying on preference of Japanese consumers on cut chrysanthemum exported. The survey was conducted two times by a local survey company in Japan, and the surveys were conducted largely on chrysanthemums for casual flowers and the altar. After departmentalizing Japanese consumers per groups the result were analyzed through conjoint and cluster methods, flower colors and shape were used relatively higher rate for selection criteria of flowers in every group in the case of casual flowers. Group 1 comprised of 60 year-old housewives who reside in a small city with high school diploma and annual income less than 300 million yen, and group 2 of 40 year-old housewives who are small city residents with high school diplomas and annual income of 300 million yen show higher rate of use in flower shape than colors. Another group 3 whose members are 50 year-old housewives, small city residents with high school diplomas and annual income of 600 million yen showed higher rate of use colors than the shape for selection criteria of flowers. The consumption characteristics according to the ages of the consumers showed a pronounced tendency. The 40-50 year-old housewives preferred single flowers packed with other flowers, and the 60 year-old housewives double flowers packed with only chrysanthemums. In flower color, the 50-60 year-old housewives preferred white and yellow flowers, and the 40 year-old housewives pink and yellow flowers. Therefore, there are needs for development strategy of new products considering the consumption characteristics of flower shape and color according to the ages of consumer. After analyzing the chrysanthemums for altar by departmentalization of Japanese consumers, every group showed relative higher rate of use for flower shape for selection criteria of flowers. According to the analysis on the consumption characteristics, group 1 which is comprised of 30-40 year-old housewives who reside in small city with high school diplomas and income less than 300 million yen, and the group 2 of 20 year-old housewives who reside in small city with college diplomas and annual income less than 300 million yen. They are very sensitive to the price of the products while the group 3 of 50 year-old housewives who reside in small city with high school diplomas and annual income less than 300 million yen are insensitive to the price. The 30-50 year-old housewives preferred white and pink flowers, and the 20 year-old housewives yellow and pink flowers. In flower shape, the 50 year-old housewives preferred anemone shape, the 30-40 year-old housewives double shape, and the 20 year-old housewives pompon shapes. Therefore, the white, double flowers for the 30-40 year-old housewives and the yellow, pompon flowers for the 20 year-old housewives are needed to be created at the lowest cost, while the white, anemone flowers are needed to created at higher cost with high quality. In light of these results, it is considered that we should understand the types of purchasing products through consumption characteristics of Japanese consumers. Also we should plan, create market-oriented and consumer-oriented products, and should export them in order to expand more exportation.

This study proposes a novel approach to explore a "travel time budget (TTB)" using a mobile phone signaling data (MPSD), which are passively generated between a mobile phone and a base station. The data analyzied in this study were provided from KT for 8 days (from May 19 to 26 in 2016). They were about 45 million signals passively generated from users whose stay area during night was classified as three areas in Mapo-gu, Seoul and in the city of Sejong. The estmation of TTB was implemented with various pre-processing techniques on the MPSD data in a data-driven analysis. As a result, the TTBs of Mapo-gu, Seoul and Sejong were 82.94 and 80.70 minutes, respectively. The results in this study were also compared with those based on the traditional methods. The authors expect that this result will help transport experts improve the use of MPSD.

Epidemiological models on disease spread attempt to simulate disease transmission and associated control processes and such models contribute to greater understanding of disease spatial diffusion through of individual's contacts. The objective of this study is to develop an agent-based modeling(ABM) approach that integrates geographic information systems(GIS) to simulate the spread of FMD in spatial environment. This model considered three elements: population, time and space, and assumed that the disease would be transmitted between farms via vehicle along the roads. The model is implemented using FMD outbreak data in Andong city of South Korea in 2010 as a case study. In the model, FMD is described with the mathematical model of transmission probability, the distance of the two individuals, latent period, and other parameters. The results show that the GIS-agent based model designed for this study can be easily customized to study the spread dynamics of FMD by adjusting the disease parameters. In addition, the proposed model is used to measure the effectiveness of different control strategies to intervene the FMD spread.

In this study, the control efficiency of odorous compounds was measured from diverse control process units of 14 individual companies located within the Ban-Wall industrial complex of Ansan city, Korea (January to July 2005), To quantify the control efficiency levels of major odorous compounds, we collected odor samples from both the front and rear side of 17 control process units ($N=17{\times}2=34$). If the control efficiency is compared for each of 32 compounds between different process units, wet scrubber (WS) was found to be the most effective unit in terms of the sum of pollutants showing the positive control signals. Although the WS system shows generally a good control pattern for VOC, it is not the case for most index odorous pollutants; only 3 out of 12 index compounds were found to show positive control efficiencies. The results of the study also indicated that the control efficiency differ greatly between different industrial sectors and/or control process types. In the case of leather industry, carbonyl compounds were found to exhibit the highest control efficiency with its values varying from 19 to 90%. On the other hand, in the case of metal production sector, VOC recorded the maximum control efficiency with values varying from 18 to 79%. According to this study, most air pollution control facilities operated in most companies show fairly poor control efficiencies for most malodor compounds. Hence, to obtain best control efficiency of odorous pollutant emission, acquisition of better information on source characteristics and establishment of effective control technologies are highly demanding.

Concentrations of carbon monoxide (CO) in air were analyzed from seven urban roadside (U-RS) stations in Seoul, Korea over an 11-year period (1998-2008). As noticeable changes in CO levels coincided with the Natural Gas Vehicle Supply (NGVS) program in the year 2000, its concentration data were examined between 1998-2000 (period I) and 2001-2008 (period II). The mean values of CO from all 7 stations for the whole study period were recorded as $1.19{\pm}0.22$ ppm with large drops in its mean from $1.83{\pm}0.43$ ppm in period I to $0.94{\pm}0.21$ ppm in period II. As such, CO levels between the two periods undertook the mean reduction rate of $46.9{\pm}16.2%$ (range of 18.3 to 59.9%). According to the analysis of longterm trends of CO, its concentrations in the U-RS stations decreased very rapidly with the annual mean reduction rate of 9.5% $yr^{-1}$. A line of evidence collected in this study suggests that the implementation of the NGVS program has been quite effective to induce the alterations in CO levels in all urban roadside locations throughout the city of Seoul.

This landscape design is a work for which we selected the square of Sejong Center for the Performing Arts as a object area, drew inhuman factors, and tried to restore them to human environment. This plan assumes that excessive urban environment results from disorder and man can keep it in order and restore it to human environment through the progressive process of speculation. In this plan, we included the least parking space and nearby roads in the object area to maximize the location feature and the symbol of cultural space, and planned that the object area may play its role of open space in the downtown. To grant the symbol of culture space, we established the progressive process of speculation and the relationship of mu, heaven and earth, and culture, geometrically diagrammatized it, combined the circular and rectangular lines derived from it, and suggested a plan. Urban environment will continue to change in the future. However, as long as it is not ensured that the change will progress upward, city would be far from human environment anyhow. Effects to display inhuman space overlooked in the downtown and restore it to human environment for citizen and location for man, should continue.

Post-Modern Multiculturalism is spreading in many ways and other cultural interest has led to the Latin American culture, which has steadily appeared as the main fashion concept of the international collection. Frida Kahlo(1907-1954), a representative of Latin American culture and a Mexican female surrealistic painter, who gives us some inspiration for contemporary fashion design. The purpose of this study is to have a correct understanding of and research on Latin American culture and to expand the expression of fashion design. In the process, this article examines the costume of Mexico belong to the Indio culture which had been regarded as the Other for a long time and understands Frida Kahlo's fashion style: Tehuanas costume and her masculine style. The Tehuanas costume is a traditional style of the city, Tehuantepec, located in the southeast of Mexico, which is characterized by colorful floral patterns and a long skirt. Three fashion concepts were derived from her fashion style: tradition & modern, love & farewell, and masculine & feminine. The scope of this study investigates the Haute Couture and the Pret-a-porter women's wear collections and photos from 1998 to 2010 in Europe, USA and South America. From classifying the collected photos into each concept, three styles such as ethnic, romantic and androgynous style were derived. These fashion styles were analyzed through the formative elements of dress, color, silhouette, pattern, material and clothing construction in order to figure out how costumes of other cultures influenced on contemporary fashion. As a design inspiration, Frida Kahlo extends her influence into innerwear, accessories and hairstyles, as well as women's wear. These inspirations emerge steadily from the past and far into the future as an expression of a fashion design concept.
