In the existing digital map of the Ver.1.0, it is impossible to make a small scale digital map, which is under the 1/5000 scale map, by using the 1/1000 digital map which is the most large scale one. Because of this reason, the existing digital maps are produced into a 1/1000 and a 1/5000 map by means of two different scale aerial photos. The next generation digital map should be successively related to a small scale digital map based on the most large scale digital one. This is so important from the aspects of data share and the consecutive renewal. Ever since the development of the digital map of the Ver. 2.0, the possibility of making a multi-scale consecutive digital map has been presented and the related research has been done again. The most basic thing in the multi-scale digital maps is to decide the criteria of the generalization between the two scales. In this study, I try to formulate the criteria of the generalization required to make the 1/5000 digital map by using the 111000 digital one. In addition, I by to explore the application possibility of the consecutive renewal by carrying out auto-generalization.

In case of a fire outbreak in a uni-directional road tunnel, the flow of traffic immediately behind the fire disaster will be stalled all the way back to the entrance of the tunnel. Furthermore, when the vehicle passengers try to flee away from the fire toward the entrance of the tunnel, the extremely hot fume that propagates in the same direction will be fatal to the multitudes evacuating, but may also cause damage to the ventilation equipments and the vehicles, compounding the evacuation process. This paper will present the 3-dimensional modelling analysis of the preventive measures of such a fume propagation in the same direction as the evacuating passengers. For the analysis, the fire hazard was assumed to be a perfect combustion of methane gas injected through the 1 m X 2 m nozzle in the middle of the tunnel, and the product of $CO_2$ as the indicator of the fume propagation. From the research results, when the fire hazard occurred in middle of the 400 m road tunnel, the air density decreased around the fire point, and the maximum temperatures were 996 K and 499 K at 210 m and 350 m locations, respectively, 60 seconds after fire disaster occurred, when the fumes were driven out only towards the exit-direction of the tunnel. By tracing the increase of $CO_2$ level over 1% mole fraction, the minimum longitudinal ventilation velocity was found to be 2.40 m/sec. Furthermore, through Analysis of the temperature distribution graphs, and observation of the cross-sectional distribution of $CO_2$ over 1% mole fraction, it was found that the fume did not mix with the air, but rather moved far in a laminar flow towards exit of the tunnel.

Since Turing (1950) proposed the development of a machine or system that could think and communicate with humans, many engineers and scientists have made endless efforts to create machines and systems that can replace humans. This effort made the field of artificial intelligence. Recently, as many people have been interested in the 4th Industrial Revolution, research on artificial intelligence technology has been actively carried out not only in the university laboratories but also in the companies as the core technology for realizing the 4th Industrial Revolution. As the artificial intelligence technology has been penetrated deeply into our lives, it is true that our lives have become much easier and more comfortable than in the past, but on the other hand, we have begun to have various negative effects. In this study, we review the social changes caused by artificial intelligence in terms of intelligent products and services. By analyzing positive effects and dysfunctions in various cases of daily life and work environment, we try to identify main policy issues.

Perm is one the of the most common thing in a beauty salon like hair-cut and hair perm needs processing solutions which is chemical substances. Those chemical substances damage the hair cuticle. Damaged hair cuticles with mistakes of perm will follow with the next performance and it will cause more damage to hair. As damage of hair cuticle become worse, it is harder to recover the hair cuticle like before. Therefore, this study shows that plain rinse is the way to reduce the damage of hair cuticle with perm as much as possible. With experiments, I suggest the right way to do plain rinse to satisfy customers' demand and reduce the damage. During the research, I figured that plain rinse with the knowledge, structure of hair cuticle, principle of perm and plain rinse, is very needed. The hair with plain rinse have more elastic curl and have less scales which came off from hair cuticle than the hair without plain rinse. This experiment concludes that hairdresser has to figure out about the time, temperature and type of water depends on the degree of damaged hair of customers. In order to perm, there is no way to not to use chemical substances to perm. Therefore, hairdresser has to choose suitable processing solutions and right steps, and as this is the age of 'well-being' boom, hairdresser must try to keep the healthy hair. Consequently, in order to meet the demands and conditions of customers, hairdresser needs to find the right method to do plain rinse and use the method in perm.

Hanbok had the history of more than 2,000 years, so Hanbok represents the traditional Korean style of dress design. Since 1980's, Hanbok has been changed to be suitable for contemporary society with diverse titles such as reformed Korean clothes, living Korean clothes, contemporary Korean clothes, and fashion Korean clothes, etc. However, Korean clothes of such a new style have not overcome a limitation in traditional styles in terms of design. In this regard, it is necessary for us to try to have the world fashion industry recognize the fashion look of 'Korean style' through the contemporary fashion of Korean image and to pursue the globalization of Korean style through this fashion. This study is firstly to review the characteristics of Korean beauty, secondly to examine the concept in Korean fashion design, and thirdly to iud out the characteristics of contemporary Korean fashion design through the study of successful cases. The characteristics of Korean beauty can be classified into natural beauty, abstract beauty, and humorous beauty. Korean beauty shows the nature and the life of Korean people, and it should make people aware of the character and the tradition of Korean culture. The Korean fashion design is the one that utilize the Korea's unique sentiment or sense of Korean beauty that has been succeeded from the ancient to the present into fashion design by way of visual element like design, color and texture. And the successful Korean fashion designs were the universal fashion designs that enable Korean culture to be hewn to the world through fashion and that enable the entire world market to agree and to accept Korean style. In order to create the global Korean design, it is necessary to assimilate the Western style to Korean style and newly create it into a compromised form. And it is necessary to look for a universal sense of Korean beauty that could be accepted by the people of the world.

The study of application using multimedia contents have been worked out a lot. But those trial can be hardly to be applied because each social study curriculum has a little difference which is a peculiar properties in social study. So we try to find the most efficient study method making multimedia contents system with computer graphic design and animation and sound and movie. This study introduce the method of image transcoding in real time based on repurposing structure to make better use of a multimedia contents system. We assume that developed multimedia contents system could be a big help to increase study efficiency through graphic, sound, movie as well as to encourage student's motive and interest. It is mostly possible to use for creative, self-controlled and social study material which is used to study the subject with conversational and repetitive way. So we hope this study will be a good guide line of developing various contents in multimedia contents.

Recently Standards Developments Organizations (SDO$\_S$) in the field of Information and Communication recognize that "More new and more complex standards should be developed in shorter time". To cope with this challenge they try to construct Standards Information Cooperation Network (SICN) or Electronic Document Handling (EDH) systems for efficient standards development process. This paper presents the design and implementation of an Extranet based Web system dedicated to effective on-line standards making environments. The system, which is called SICN (Standards Information Cooperation Network), is a workflow-based network application created with a view to fostering faster standards development with functionalities such as an electronic signature mechanism, electronic voting, comment gathering and dynamic links for ready retrieval of standards information stored in a database. This paper also describes the concept of a VSDO (Virtual Standards Development Organization) that supports all the features needed by the relevant standards making bodies to carry out their activities in dynamic on-line environments.ironments.

The purpose of this study were to examine the types of apparel store, to investigate consumer characteristics related to the apparel store patronage behaviors, and to find out the differences of casual relationships on apparel store patronage behaviors in store types. Data were collected from 451 consumers living in Pusan and analysed by factor analysis, ANOVA and path analysis. The results were as followings : First, the types of apparel store recognized by consumers were composed by five factors such as Casual-wear store, Traditional market store, Neighboring store, Department store, and Small-sized department store. Second, apparel store patronage behaviors have significant differences recreational and economic shopping orientations, Fashionability in store evaluative creteria, social psychologic risks in perceived risks, and observation store information source. Third, there were differences in casual relationships an apparel store patronage behaviors across store types. Casual-wear store patronage behaviors were directly influenced by the information source, and traditional market store patronage behaviors did by the perceived risk. Apparel shopping orientations directly influenced Neighboring store, and department store patronage behaviors. Evaluative creteria of store directly did small-sized department store. That is, consumer characteristics directly influencing to patronage behaviors were different across apparel store types. Therefore, the marketers of apparel store should understand consumer characteristics related to patronage behaviors and affecting variable and then try to encourage consumer's store patronage behavior.

It has not been a long time since a comparative advertising was emphasized in the advertising industry and academics. The issue is whether comparative advertising is more effective than noncomparative advertising, and if it is true, then under what conditions it is more effective. Based upon previous research results and expertises' opinions, the authors try to figure out the hierarchy of comparative advertising effect and its determinants. The objective of this exploratory study is to develop a conceptual model on comparative advertising effect and research propositions. This model would provide us with broader understanding on comparative advertising, practical guidelines for comparative advertisement production, and foundations of developing more detailed model on comparative advertising effectiveness.

There are several reasons to take X-ray in case of inpatients. Some of them who cannot ambulate or have any risk if move are taken portable X-ray at their wards. Usually, in this case, many other people-patients unneeded X-ray test, family, hospital workers etc-are indirectly exposed to X-ray by scatter ray. For that reason I try to be aware of free space scatter dose accurately and make the point at issue of portable X-ray better in this study. kVp dose meter is used for efficiency management of portable X-ray equipment. Mobile X-ray equipment, ionization chamber, electrometer, solid water phantom are used for measuring of free space scatter dose. First of all the same surroundings condition is made as taken real portable X-ray, inquired amount of X-ray both chest AP and abdomen AP most frequently examined and measured scatter ray distribution of two tests individually changing distance. In the result of measuring horizontal distribution with condition of chest AP it is found that the mAs is decreased as law of distance reverse square but no showed mAs change according to direction. Vertical distribution showed the mAs slightly higher than horizontal distribution but it isnt found out statistical characteristic. In abdomen AP, compare with chest AP, free space scatter dose is as higher as five-hundred times and horizontal, vertical distribution are quite similar to chest AP in result. In portable X-ray test, in order to reduce the secondary exposure by free space scatter dose first, cut down unnecessary portable order the second, set up the specific area at individual ward for the test the third, when moving to a ward for the X-ray test prepare a portable shielding screen. The last, expose about 2m apart from patients if unable to do above three ways.
