This study is to provide basic data for the development of domestic ready-made shoes industry by illustrating any problem in regards to the ready-made shoes for ordinary salary men through looking into its uses and gratifications. Subjects for this study were in between twenties and sixties by applying convenient random sampling method, which was done in January to February, 2001. The results were as follows: 1. General foot shape of subjects was that foot breadth was wide whereas instep height was average. In regards to the metamorphic parts of foot, the most metamorphic part was the fifth toe which could be occurred by disagreeable shoes to foot. 2. General salary men (69.5%) wear the formal shoes and their wearing time per day is over 10 hours (49%), which illustrates that more suitable and convenient functional shoes needs to be developed. 3. Almost of subjects tended to purchase ready-made shoes, and their concerns to be considered when to purchase ready-made shoes were its size and solidity. This finding suggests that the size specification of the ready-made shoes needs to be more specific in terms of its length as well as foot breadth. 4. The most unsatisfied point on the ready-made shoes was the foot breadth. According to the Crosstabulation analysis on the discomfort part and the foot breadth, there existed a significant correlation between the discomfort part and the foot breadth (p$\leq$0.05). The above results make clear that overall salary men have complaints on the ready-made formal shoes in terms of its size and wearing comfort level. This suggests that the subdivision of the shoes size specification needs to be developed to improve the wearing comfort level.

This study aims to investigate the characteristics of Chinese consumers, who are growing up as the global biggest consumption market, according to G sensibility types, and to provide the data base for China market by analyzing the consuming pattern per sensibility and the preferred color. For the investigation, the survey on G sensibility and consuming pattern was conducted for consumers in four cities of China. As a result of classification of G sensibility types, it was found that Chinese consumers tended to behave in accordance with their values and identities and the most general type in them was G1 pursuing the reasonable and logical consumption, unlike Korean consumers who tended to be shown as G3 for the most general type according to the preceding study. As to characteristic of consumption, Chinese consumers preferred to purchase clothes from the department store, and in case of G2 type, the characteristics was corresponded with Actionist's character which shows the wide range of behavior and high-consumption, by preferring the road-shop next to the department store. Chinese consumers tended to purchase the clothes on the basis of their preferred colors, and especially it was shown that achromatic color was very commonly preferred. Also the black color was on the highest preference, and white, dark gray and light gray were followed. Meanwhile, in chromatic color, it was found that brown, orange, red and blue were preferred in order, and in case of G4, it was found that they preferred more various colors compared to the other types. This result could be used as the data base for the marketing strategy of fashion design industry and the related companies, as well as the new communication method for the consumers.

The purpose of this study is to find out suggestions for government policy and expansion of consumption of environmental-friendly agricultural products(EFAP). For this purpose, we did research on purchasing pattern of EFAP and understanding of government environmental-friendly agricultural policy. First, the purchase of EFAP has been increased, because EFAP is safer. Consumers prefer department store because it is easier than any other marketing. Difficulties which consumers are facing when they purchase EFAP are price and credibility and small number of stores. Most favorable item is vegetable and the price of rice which consumers are willing to pay is really high. Second, not many consumers do recognize the label and system of EFAP. Third, most famous authentication institution agricultural products quality management service and other institutions are not recognized. Consumers recognize the certificate of origin. The government policy for safe food consumption is to intensify government supervision on foods. Suggestions from these results are as follow: First, the urgent problem to expand consumption of EFAP is credibility of EFAP. To make consumers trust EFAP, these are considered as useful solutions, i.e. recall, quality management service, standardization, and better quality. Second, government should be continue public relation, education and supervision of EFAP. Third, quality management should be continued. Not only central government but also local quality management institutions should continue quality management service. Last, local government should help farmers of EFAP to solve the difficulties of marketing.

This study looks at the patterns of married women's lifestyles and verifies whether there are differences in their preferences, the will to continue shopping, and the importance of healthy foods. The paper analyzes the relative influence of each lifestyle pattern on the level of satisfaction with healthy foods. The results of the analysis of this study are as follows. To find patterns in the lifestyles of married women ages 20s to 50s, the factors were analyzed and five lifestyle patterns were extracted: health managing type, fashion pursuing type, self-expressing type, family-oriented type, and eco-friendly type. If we examine the purchasing of healthy foods for each lifestyle, women with a self-expressing lifestyle gain more information from news articles, books, and salespeople than from other information sources. Women of the health managing, family-oriented, and eco-friendly types had high purchasing frequencies and amounts. A cluster analysis was carried out to categorize the different groups being investigated into lifestyle types. They were categorized into the four clusters: active multiple-oriented type; fashion, self-expressing compromising type; passive well-being oriented type; and family and health managing type. It has been verified that there are differences among the clusters in terms of the level of importance of products, contributions to health, as well as distribution and management of healthy foods. To be more specific, the level of importance of the products as well as their distribution and management manifested as being higher among the active multiple-oriented type and the family-oriented and health managing types. The level of importance of contributions to health scored high among all groups, except the passive well-being oriented type. The active multiple-oriented type and the family-oriented and health managing types showed a high level of preference and will to continue purchasing healthy foods, while the fashion and self-expressing compromising types and passive well-being oriented type showed a low level of preference and will. In order to find patterns in the level of satisfaction with healthy foods, three factors were analyzed: credibility of labels, contributions to health, and satisfaction with the store. The factors that had the greatest influence on the total level of satisfaction was the credibility of labels for the family-oriented lifestyle; a product's contribution to health for the health managing lifestyle; and the store for the fashion pursuing lifestyle.

Consumer's perception and consumption pattern of fresh-cut agri-food Products were surveyed to Provide basic information for quality enhancement. The results are summarized as follows: The respondents had a preference for a discount store (60.5$\%$) to purchase fruits and vegetables and the frequency of purchase was one time Per week (46.1$\%$). Fruits and vegetables were purchased frequently by full-time housewives compared with workers. The reasons for purchasing fresh-cut agri-food generally resulted from a consideration of the saving in cooking time, the ease of handling and the desire to serve appropriate portions. On the other hand, the reasons for not purchasing fresh-cut agri-food Products were the comparatively high price, a perception of unsanitary handling. Freshness was considered to be the most important factor when purchasing these products. The preferred price for the fresh-cut agri-food products were approximately 110 $\∼$ 140$\%$ of that for the unprocessed products. 87.7$\%$ of respondents answered that they will purchase fresh-cut agri-food products continuously if some problems that they considered, would be improved.

The purpose of this study is to investigate the importance of well-being related to lifestyle choices such as food habits, food choices, life pattern, etc. The survey was conducted among college students using a questionnaire and a 5-point Likert score in Seoul City and Kyunggido Province during September 2005. The responses of 968 college students were analyzed by the SPSS program. The results were as follows. Most of the subjects were female(76.2%), and lived with their parents (85.6%). The average score of 'food habits', 'choosing food materials', 'purchasing' and 'life pattern' were $2.71{\pm}1.22,\;2.86{\pm}1.28,\;2.41{\pm}1.21,\;and\;2.97{\pm}1.31$ respectively in males and $3.01{\pm}1.20,\;3.00{\pm}1.32,\;2.55{\pm}1.20,and\;2.68{\pm}1.40$ in females, respectively. In regard to 'food habits', the scores were significantly affected by gender(p<0.001), smoking(p<0.05), alcohol consumption(p<0.05), exercise(p<0.001), weight satisfaction(p<0.001), method of weight control(p<0.001), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001), and whether the individual tried a well-being item(p<0.001). In regarding to 'choosing food materials' the scores were significantly affected by gender(p<0.001), smoking(p<0.05), exercise(p<0.001), weight satisfaction(p<0.05), method of weight control(p<0.05), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001) ), and whether the individual tried a well-being item(p<0.001). Out of the factors affecting 'purchasing', the association with BMI was remarkable. Students who were overweight, obese or underweight showed higher average scores than students of normal weight. The primary concerns and trial of well-being of college students were food and exercise. Therefore, the purchase of well-being goods is related to their weight control in college students. In regard to 'life pattern' the scores were significantly affected by exercise(p<0.01), use of computer(p<0.001), BMI(p<0.001), weight control(p<0.001), use of nutritional supplement(p<0.05), regularity of breakfast(p<0.001), level of interest in wellbeing(p<0.001), whether the individual tried a well-being item(p<0.001), and having taken lecture on well-being(p<0.05). Therefore nutrition education is needed for healthy eating habits of college students and it is necessary to develop a series of lectures to teach them about diet and exercise programs.

Sequential pattern mining aims to discover interesting sequential patterns in a sequence database, and it is one of the essential data mining tasks widely used in various application fields such as Web access pattern analysis, customer purchase pattern analysis, and DNA sequence analysis. In general sequential pattern mining, only the generation order of data element in a sequence is considered, so that it can easily find simple sequential patterns, but has a limit to find more interesting sequential patterns being widely used in real world applications. One of the essential research topics to compensate the limit is a topic of weighted sequential pattern mining. In weighted sequential pattern mining, not only the generation order of data element but also its weight is considered to get more interesting sequential patterns. In recent, data has been increasingly taking the form of continuous data streams rather than finite stored data sets in various application fields, the database research community has begun focusing its attention on processing over data streams. The data stream is a massive unbounded sequence of data elements continuously generated at a rapid rate. In data stream processing, each data element should be examined at most once to analyze the data stream, and the memory usage for data stream analysis should be restricted finitely although new data elements are continuously generated in a data stream. Moreover, newly generated data elements should be processed as fast as possible to produce the up-to-date analysis result of a data stream, so that it can be instantly utilized upon request. To satisfy these requirements, data stream processing sacrifices the correctness of its analysis result by allowing some error. Considering the changes in the form of data generated in real world application fields, many researches have been actively performed to find various kinds of knowledge embedded in data streams. They mainly focus on efficient mining of frequent itemsets and sequential patterns over data streams, which have been proven to be useful in conventional data mining for a finite data set. In addition, mining algorithms have also been proposed to efficiently reflect the changes of data streams over time into their mining results. However, they have been targeting on finding naively interesting patterns such as frequent patterns and simple sequential patterns, which are found intuitively, taking no interest in mining novel interesting patterns that express the characteristics of target data streams better. Therefore, it can be a valuable research topic in the field of mining data streams to define novel interesting patterns and develop a mining method finding the novel patterns, which will be effectively used to analyze recent data streams. This paper proposes a gap-based weighting approach for a sequential pattern and amining method of weighted sequential patterns over sequence data streams via the weighting approach. A gap-based weight of a sequential pattern can be computed from the gaps of data elements in the sequential pattern without any pre-defined weight information. That is, in the approach, the gaps of data elements in each sequential pattern as well as their generation orders are used to get the weight of the sequential pattern, therefore it can help to get more interesting and useful sequential patterns. Recently most of computer application fields generate data as a form of data streams rather than a finite data set. Considering the change of data, the proposed method is mainly focus on sequence data streams.

This paper deals with an integrated problem of inventory control and dynamic pricing strategies for a commodity with price and sales-period dependent demand pattern, where a seller and customers have complete information of each other. The problem consists of two parts; one is each buyer's benefit problem which makes the best decision on price and time for buyer to purchase items, and the other one is a seller's profit problem which decides an optimal sales strategy concerned with inventory control and discount schedule. The seller's profit function consists of sales revenue and inventory holding cost functions. The two parts are closely related into each other with some related variables, so that any existing general solution methods can not be applied. Therefore, a simplified model with single seller and two customers in considered first, where demand for multiple units is allowed to each customer within a time limit. Therewith, the model is generalized for a n-customer-classes problem. To solve the proposed n-customer-set problem, a dynamic programming algorithm is derived. In the proposed dynamic programming algorithm, an intermediate profit function is used, which is computed in case of a fixed initial inventory level and then adjusted in searching for an optimal inventory level. This leads to an optimal sales strategy for a seller, which can derive an optimal decision on both an initial inventory level and a discount schedule, in $O(n^2)$ time. This result can be used for some extended problems with a small customer set and a short selling period, including sales strategy for department stores, Dutch auction for items with heavy holding cost, open tender of materials, quantity-limited sales, and cooperative buying in the on/off markets.
