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.

It was the turning point in the "fixed point arena" when the notion of weak commutativity was introduced by Sessa [9] as a sharper tool to obtain common fixed points of mappings. As a result, all the results on fixed point theorems for commuting mappings were easily transformed in the setting of the new notion of weak commutativity of mappings. It gives a new impetus to the studying of common fixed points of mappings satisfying some contractive type conditions and a number of interesting results have been found by various authors. A bulk of results were produced and it was the centre of vigorous research activity in "Fixed Point Theory and its Application in various other Branches of Mathematical Sciences" in last two decades. A major break through was done by Jungck [3] when he proclaimed the new notion what he called "compatibility" of mapping and its usefulness for obtaining common fixed points of mappings was shown by him. There-after a flood of common fixed point theorems was produced by various researchers by using the improved notion of compatibility of mappings. of compatibility of mappings.

In spite of enormous increase in data generation, its practical usage in the construction sector has not been prevalent enough compared to those of other industries. The author would explore the obstacles against efficient data application in the arena of expenditure forecasting, and suggest a forecasting method by applying Case-based Reasoning (CBR). The newly suggested method in the research, enables project managers to forecast monthly expenditures with less time and effort by retrieving and referring only projects of a similar nature, while filtering out irrelevant cases included in database. Among 99 projects collected, the cost data from 88 projects were processed to establish a new forecasting model. The remaining 10 projects were utilized for the validation of the model. From the comprehensive study, the choice of the numbers of referring projects was investigated in detail. It is concluded that selecting similar projects at 12~19 % out of the whole database will produce a more precise forecasting. The new forecasting model, which suggests the predicted values based on previous projects, is more than just a forecasting methodology; it provides a bridge that enables current data collection techniques to be used within the context of the accumulated information. This will eventually help all the participants in the construction industry to build up the knowledge derived from invaluable experience.

It is important to maintain on operational availability of aircraft during wartime. The KF-16 fighter, the backbone of the ROKAF (Republic Of Korea Air Force), has a single engine. Therefore, the engine has a critical influence on operational availability. The purpose of this study is to estimate optimal levels of spare part inventories concerning both engines and modules. That is provided by linear programming methods utilizing a developed meta-model. For drawing out the meta-model, we develop a simulation model which can consider wartime demands. In the previous study, $2^k$ factorial design method is used to check the influence of each independent variable. That method requires relatively many scenarios because every extreme value combination of independent variables should be checked. However, this study adopts NOLH (Nearly Orthogonal Latin Hypercube) as an experimental design. By adopting NOLH, this study increases not only efficiency but also accuracy. That is proven by comparing the validity of the developed meta-model on both experimental designs. This study also utilizes the OptQuest simulation tool in ARENA to derive the optimal level of spare stocks. By comparing the result of OptQuest to that of the developed meta-model, the validity of this study is secured.

The core purpose of the paper is to explore perceptual displays of rural India towards the role and impact of ICT in transforming the lives through education and telecommunications. After meticulous review of pertinent literature on ICT, and its policy framework, the researcher administers both quantitative and qualitative field data collected from the villages of Andhra Pradesh, Karnataka, Kerala, and Tamil Nadu with a sample of 250 from each state. More than 90 percent of respondents from the four southern states in India clearly thought that the role and impact of ICT is very momentous. Predominantly, cent percent respondents from Kerala evinced that ICT is the major reason for achieving the tag of "100% Literacy State". And also in the remaining three states viz., Andhra Pradesh, Karnataka, and Tamil Nadu, the literacy rate has crossed mind-boggling figures only because of ICT's reinforcement. Even in the arena of telecommunications, these four states average telecom density is more than the country's average. The paper concentrated only on how ICT function empirically to build human capacity in rural south-India through the sectors of only education and telecom. This study is first of its kind and precious to all stakeholders of the ICT sector like educational institutional, telecom firms, customers, employees, and governments, etc.

As railroad industry faces the new Renaissance era, effective and efficient maintenance methods for rolling stock operation are required with advanced railroad technology. All kinds of railroad systems such as high-speed long-distance train, metropolitan mass transit and light rail require systematic maintenance technology in order to maintain the safe railroad operation. Simulation models for regular operations of the example maintenance center are developed. In this study, standard maintenance procedures, layout, equipments, and number of workers of Siheung Metropolitan Railroad Maintenance Rolling Stock Depot are considered. The proposed simulation models are developed using simulation package ARENA. After simulation, four types of observations are analyzed. First, the bottleneck operation is identified. Second, the relationship between maintenance center size, number of workers and cycle time is analyzed. Third, the scheduling performances between PERT/CPM and Critical Chain Project Management(CCPM) are compared. Lastly, the simulation results according to worker's working coverage shows expanding the worker's coverage decreases the cycle time and increases throughput per train. However, workers are to be fully trained to do multiple skill work.
