These days the Korean costume becomes the formal dress to be worn on particular occasions. The Westernization of life style, inculding dress, has made the costume of wearing traditional dress disappear from Korean's everyday life. This study is launched to investigate the precious textiles and materials of the past before they vanish; this study deals with the materials of folk costume in the early 20th century, preceding Westernization. The research method adopted in the study was interviews of fifth- five elderly persons living around the Mt. Kumo area in Gyungbuk province. The result was that costume culture in that area was poor because people living in the area were economically less well off due to meager agricultural products. There was no variety in the style of costumes to be worn for various occasions. It was also nothworthy that because of no diversification in naming, only one representative word was used to name several types of costumes. On the other hand, it was discovered that the people in the Mt. Kumo area had religious aspirations stemming from their folk beliefs concerning costumes. They also had an attitude of saving money despite poor economic conditions.

There is a growing global interest in food choices that could affect health. Consumer food choices are dictated by numerous factors such as attitudes, beliefs, desires and preferences stemming from psychological and physiological attributes. The present study aimed to understand consumers' internal perceptions about cream soup, cream sauce, and tomato sauce using ZMET (Zaltman's Metaphor Elicitation Technique). The 9 step ZMET interview process was conducted for a sample of 36 consumers (12 consumers for each sauce). A content analysis of the survey results was carried out. From this, 56 concepts of cream soup were derived, and 15 constructs that met with the agreement of more than one-third of the total sample consumers were extracted. These 15 constructs included 'Soft', 'Recollection', 'Familiar', 'Warm', 'Comfortable', etc. Similarly, for cream sauce, 67 concepts and 20 constructs 'Silky', 'Warm', 'Restaurant', 'Family', 'Memory', etc. were deduced. A total of 66 concepts and 20 constructs for tomato sauce 'Sourness', 'Sauce Bottle', 'Pleasant', 'Ingredient', 'Cooking', etc. were derived. The analysis of consumers' consensus maps through this study provides a deep and useful understanding of consumers and their latent needs. Also, the results of this study indicate that exploring consumers' internal perceptions is critical to understanding their healthy food choices. This can be used as basic data for formulating marketing strategies.

The traditional methodology of Korean regional studies had been shifted by geographic thoughts and philosophy as follows; Environmentalism or Environmental determinism stemming from geomancy were dominant methodology in the Korea era. An idiographic approach was introduced based on the encyclopedic description of geographic factors of villages for the centeralization of power in the Chosun era. A systematic geography that pursues scientific laws of regional differences which results from the interactions of human and nature had emerged through field works of some practical school in the later Chosun era.

We're living in a world of one global village. The globalization of business is acceleration as more companies cross national borders to find customers, materials and money. Many foreign companies and organizations are doing their business aggressively in Korea and many Korean companies and rushing into foreign market. When people communicate for business with someone from another culture, there could be difficult communication barriers to overcome resulting from differences in their values, beliefs, norms for behavior, expectations, attitudes and so on. To do successfully business, we need to understand culture background and communication style that is different from nation, race, language. Communication barriers stemming from cultural differences may vary. Largely, they can be divided into value system, non-verbal communication, and perception process. Value system can be divided into individualism versus group orientation, avoidance of uncertainty degree, power distance, and high- context culture versus low-context culture. Also non-verbal communication method and perception process may play decisive roles in communication effectiveness. Especially nonverbal communication barriers which sometimes play more important roles than the verbal parts are composed of eye contact, gesture, kinesics, proxemics, chronemics, paralanguage and language of color Cross-cultural communication affect business situation. I expect that if we understand cultural background, and then we overcome cross-cultural communication barriers. To overcome and to adapt inter-cultural business, we need to develope curriculum on the cross-cultural education which I will study in the next paper.

In this paper, we propose a fast warping prediction using bit-pattern for motion estimation. Because of the spatial dependency between motion vectors of neighboring node points carrying motion information, the optimization of motion search requires an iterative search. The computational load stemming from the iterative search is one of the major obstacles for practical usage of warping prediction. The motion estimation in the proposed algorithm measures whether the motion content of the area is or not, using bit-pattern. Warping prediction using the motion content of the area make the procedure of motion estimation efficient by eliminating an unnecessary searching. Experimental results show that the proposed algorithm can reduce more 75% iterative search while maintaining performances as close as the conventional warping prediction.

The South Korean society is rapidly aging, thereby highlighting the need to urgently prepare for the stabilization of housing for the elderly. In order to address such issues stemming from the elderly population, the South Korean government has been ramping up the supply of public silver houses for the elderly. Furthermore, it is necessary to select the optimal construction sites and conduct financial feasibility study on the selected sites in order to ensure a successful supply of public silver houses. In this study, the author proposed the need for building an integrated database by using geographic and demographic information, as well as the information on social welfare costs. Moreover, a concept for a system capable of performing optimal site analysis and feasibility study using the aforementioned information was suggested.

Hospitals tend to provide uniformed service to patients despite their various demands stemming from the severity of disease stages or the uncertainties in information of treatment stages. To identify service factors and provide effective contextually aware service models that patients demand depending on their evolving circumstances, the study conducted a survey on service quality based on importance and satisfaction of cancer patients. The study surveyed 286 patients and caregivers on importance and satisfaction through a questionnaire comprising of 17 questions at the outpatient clinic of cancer centers of university hospitals in 5 cities. Based on the risks of the disease and uncertainties in information of treatment stages, the cancer patients were grouped into diagnosis stage; low-risk treatment stage; high-risk treatment stage; stabilization stage. Depending on the patient's situation, the importance and satisfaction of service factors were ranked. These factors were categorized into 4 groups from a managerial perspective into 'keep it up area', 'focus here area', 'low priority area', 'overdone area'. This study provides an effective medical service model that can accommodate patients based on management areas of cancer patients.

A method to detect lots of porno documents on the internet is presented in this parer. The proposed method applies fuzzy inference mechanism to the conventional information retrieval techniques. First, several example sites on porno arc provided by users and then candidate words representing for porno documents are extracted from theme documents. In this process, lexical analysis and stemming are performed. Then, several values such as tole term frequency(TF), the document frequency(DF), and the Heuristic Information(HI) Is computed for each candidate word. Finally, fuzzy inference is performed with the above three values to weight candidate words. The weights of candidate words arc used to determine whether a liven site is sexual or not. From experiments on small test collection, the proposed method was shown useful to detect the sexual sites automatically.

This paper presents a torque distribution algorithm for improving the stability and mobility of a wall-climbing robot platform. During ascent, the pitch moment caused by the payload or external disturbances separates the robot's triangular tracks from the wall, significantly deteriorating its stability. Moreover, the reaction forces stemming from the increase in the pulling force may degrade the robot's mobility. Thus, it is very important to minimize the reaction forces acting on the triangular tracks, as well as the fluctuations in the pulling force, during the climb. Through dynamic modeling of the proposed robot platform, we demonstrated the dependence of the robot's stability and mobility on the torque distribution of the triangular tracks. Extensive simulations using different climbing speeds were used to significantly improve the stability and mobility of the proposed robot platform.

The fabric braided braking hose that delivers the driver's braking force to brake cylinder undergoes the large deformation cyclic motion according to the steering and bump/rebound motions of vehicle. The cyclic large deformation of braking hose may give rise to two critical problems: the interference with other adjacent vehicle parts and the micro cracking stemming from the fatigue damage accumulation. Hence, both the hose deformation and the fatigue damage become the critical issue in the design of braking hose. In this context, this paper introduces a multi-objective optimization method for minimizing the both quantities. The total length of hose and the helix angles of fabric braided composite layers are chosen for the design variables, and the maximum hose deformation and the critical fatigue life cycle are defined by the individual single objective functions. The trade-off between two single objective functions is made by introducing the weighting factors. The proposed optimization method is validated and the improvement of initial hose design is examined through the benchmark simulation. Furthermore, the dependence of optimum solutions on the weighting factors is also investigated.
