In this paper we introduce the Internet-based purchase support systems using data mining and case-based reasoning (CBR). Internet Business activity that involves the end user is undergoing a significant revolution. The ability to track users browsing behavior has brought the vendor and end customer's closer than ever before. It is now possible for a vendor to personalize his product message for individual customers at massive scale. Most of former researchers, in this research arena, used data mining techniques to pursue the customer's future behavior and to improve the frequency of repurchase. The area of data mining can be defined as efficiently discovering association rules from large collections of data. However, the basic association rule-based data mining technique was not flexible. If there were no inference rules to track the customer's future behavior, association rule-based data mining systems may not present more information. To resolve this problem, we combined association rule-based data mining with CBR mechanism. CBR is used in reasoning for customer's preference searching and training through the cases. Data mining and CBR-based hybrid purchase support mechanism can reflect both association rule-based logical inference and case-based information reuse. A Web-log data gathered in the real-world Internet shopping mall is given to illustrate the quality of the proposed systems.

As a result of imminent recognition on nature from modern world, the need for the combination between architecture and nature has been raised as another topic in architectural arena, and this kind of work is being conducted under the notion of Landscape. As the term 'Landscape' emerges as the key word in contemporary architecture, 'Landscape' begins to transcend the mere meaning of landscape architecture(gardening). The word, Landscape, has gone beyond the meaning of mere landscape, or rural vista one-dimensionally, and, after having introduced the attributes of nature into building activities, has emerged as a notion trying to form 'the architecture as landscape.' Together with these, 'Landscape' is expanding as a notion having various layers. The notion's, 'Landscape', occupying the significant position in contemporary architecture has been a recent phenomenon over 1980-1990s, and its category of practice has not certain limitation, rather it has started simultaneously from various areas. This study, before reviewing the architectural notion of Landscape by studying the Landscape notion and its various embodying methods being shown in contemporary architecture. As a result of examining the features of Landscape notion shown in various directions(ways), being influenced by the four Landscape types presented by Eduard Bru and the currents of the times, we can see that, though the features are somewhat similar, they are classified and explained as different types respectively. So, we are able to recategorize the features into 6 domains in this study.

This study aimed to analyze the types and characteristics of space forms according to the composition of the stage and auditorium space along with the expression trends in the space of performing arts centers through the cases of modern performing arts centers in America. Today since the purposes of performance are multiple, a variety of stage types are applied to each performing arts center. They use various spaces and performances of multiple purposes by moving and transforming the stage and auditorium according to the kinds of performance as a variation of the arena stage. In today's performing arts centers, the sizes of the stage and auditorium can vary widely, and the performances of many different genres are put to multiple purposes. There appear complex performing arts centers that can plan performing spaces of diverse sizes and forms to fit the functions of a performance in a large building. Since they put on performances in a large space according to the characteristics of the kind of performance, the intentions and goals of the performance are well delivered to the audience.

In Postal logistics, the efficient design and operation of transportation network is very important issue. But, it is hard to operate the postal transportation network flexibly according to the change of mail volume. In Korea post, a transportation plan is pre-determined and the transportation of mail is performed through the routes in the plan. When the routes cannot transport all mail, temporary vehicles are used. In the postal transportation, it is important to make a good transportation plan and to manage the plan efficiently. But the change of transportation plan is not a simple work because hundreds of vehicles and persons are related to the plan. So, a methodology to check the effect of the change of the transportation plan in advance is required. In this paper, we develop a simulation model to evaluate the performance of a postal transportation plan. We implement the simulation model and develop an information system including user interface for managing data and simulation results. We apply our simulation model and system to the real change of transportation plan.

In this paper, we discussed a problem for improving the throughput of a crankshaft manufacturing line in an automotive factory in which the budget for purchasing new machines and installing additional buffers is limited. We also considered the constraint of available space for both of machine and buffer. Although this problem seems like a kind of buffer allocation problem, it is different from buffer allocation problem because additional machines are also considered. Thus, it is not easy to calculate the throughput by mathematical model, and therefore simulation model was developed using $ARENA^{(R)}$ for estimating throughput. To determine the investment plan, a modified Arrow Assignment Rule under some constraints was suggested and it was applied to the real case.

The medical service, accompanied by various disease and disease of modern people, must collect various information about patients through various tests, and demand continued to increase. As a result, interest in waiting time for medical services is rising, and various studies are underway to reduce waiting time. However, medical procedure is complex and diverse in the procedure of the services need to be conducted for each procedure. In this study, we are going to propose ways to improve the waiting time of the test procedures that are basically experienced by outpatients through the simulation experimental method. Based on the actual measurement data, the Arena Simulation program was used to implement the hospital's ophthalmic examination model and alternative model. Through this analysis, the waiting time of the examination procedure, the size of the queue, and density of the waiting room were analyzed.

Korea may have the social environment that has a high interest and demand for the fashion industry, but the relative importance that the Hanbok industry occupies in the fashion industry is very low. It can be found that this is attributed to the difficulty in identifying the trends of Hanbok due to the smallness of Hanbok material producers and Hanbok producers, a change in consumers' consciousness of Hanbok, the difficulty of ties and integration between Hanbok-related organizations, the lack of support from government and the like. Given the recent trend that the principal factor that enables the Korean fashion industry to be competitive in the world fashion business community is based on the beauty of Hanbok, this indifference to the Korean Hanbok industry would be the roadblock to internationalizing the Korean fashion industry. Accordingly, this study attempted to identify the problem of Hanbok-rela1ed department as the basic work for the development of the Hanbok industry and present the plan to activate it, thereby providing basic materials for exploiting the new arena of the Hanbok cultural industry the domestic and foreign fashion market in the 21st century.

The purpose of this study is to introduce and research the traditional Korean costume collections of Dr. McCune who was born in Pyung-Yang in 1907 and resided until her marriage to George S. McCune in about 1930. Her collections consist of three categories : children's costumes, adults' costumes, access-ories. The characteristics of collections are summorized as follows : 1. Deep wrappings are found at the front part of the top clothing when worn. The front gusset (SUB) has been dramaticaly tilted due to the difference in lengths of the top and bottom parts of the front gusset. 2. Assymetry was one of the principles of decorating Korean costumes. The assymetry were repeated at the GIT and SUB of CHOGORE with patchwork patterns. 3. Primary colors were favored in Korean costume. Hue contrast in color combinations was prefered as well, such as : yellow CHOGORE and purple blue CUFFS, a red SUN pattern matched with green embroidery. 4. Surface patterns were not so popular in Korean costumes, while the most colorful and fabulous patterns were shown through the various embroidery artifacts. Patterns were used as a way of expressing of their desires or longings in Korean costumes. The main themes of the patterns were longevity and happiness. The patterns such as peony, lotus, chrysanthemum, bamboo and bat were implying symbolism at that time. 5. Natural materials were prefered for the garments, Silk and cotton were used as the main materials of the costume collections. Studies of Korean Costume collections owned by international collectors are meaningful to boost the arena of Korean Costumes as well as fill up the vacancy left by lost costume artifacts.

In this study homosexuality as a discourse represented in contemporary fashion magazines is explored in context. The main concerns are the contemporary construction of homosexuality, fashion symbols to identify homosexuals, and relationships between homosexuality and heterosexual masculinity in fashion images today. After elaborating homosexuality conceptualized historically, an analytical framework from Foucault's discursive approach was made up to interpret the fashion spreads since 2000. As a result, as it is assumed that the concept of homosexuality is constructed by historical specificity, homosexual fashion styles are dynamic. So, it should be recognized that they are formed by power relationships with heterosexuality, and other social factors such as class, race, age, and consumer culture and market trends. On the basis of photographic themes and fashion looks homosexual images are classified into 3 kinds of versions, the effeminate trend setter, the masculine athlete or biker, and the neo camp. However, most of contemporary homosexual photographs are not also so conspicuously different from heterosexual ones. Therefore, in the contemporary structure at least from fashion images, homosexuals can be recognized equally with heterosexual people only except for sexual preference. Thus, homosexual fashion also shares a lot of fashionable products with heterosexual one, with often homosexuals' role as trend -setter.

A production system in domestic shoes companies has difficulty in achieving automation and information because of insufficiency of flexibility and standardization. Particularly small and medium sized shoes companies producing by OEM have tendency to chase the given production schedule blindly without considering major factors that may affect the production. Therefore, the production schedules or the process conditions can not be optimally set and are extemporized by the experience in the past. These behaviors cause low productivity and financial loss. To maximize efficiency and productivity of the shoe-making process, we develop a simulation model based on a production system in small and medium sized shoes companies. The model has been developed using ARENA which has been demonstrated to be a powerful tool to simulate various manufacturing systems. Using the simulation model, we find out several problems for the production process, and then suggest several alternatives to improve the system.
