The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social, economical influence of the elderly population has been increasing, too. Research regarding elderly people is important because many elderly people take care of their appearance and clothing, and clothing plays an important role in the elderly women's everyday life. This study investigated the life satisfaction, appearance satisfaction, and clothing behavior of women aged 55 years and older who were residents of Seoul. The results of this study are as followings: 1. The importance of various factors on clothing behavior is different. They are management, clothing importance, fashion indifference, information search and purchase planning, clothing dependence, status symbol, and conformity in order of the importance. 2. Age has a positive relationship with each of fashion indifference and clothing dependence, but a negative relationship with information search and purchase planning. 3. Age has a positive relationship with each of life satisfaction and allowance. 4. Appearance satisfaction is positively related with age, but is significantly related with neither allowance nor education. 5. There are positive relationships between life satisfaction and all clothing behavior factors except status symbol. 6. Appearance satisfaction are siginicantly correlated with management, conformity, clothing dependence, and clothing importance. And life satisfaction has more significant relationship with clothing behavior than appearance satisfaction does.

Objective: We propose to apply color information to facilitate finding books in the library. Background: Currently, books are classified in the basis of a decimal classification system and a call number in the library. Users find a book using the call number. However, this classification system causes various difficulties. Method: In a process analysis and survey study, we identify what the real problem is and where the problem is occurred. To solve the real problems, we derived a new search method using color information. We conducted a comparative experiment with 48 participants to see whether the new method can show higher performance. Results: The new method using color information showed faster time and higher subjective rating scores than current call number method. Also, the new method showed faster time regardless of the skill level while the call number method showed time differences in terms of the skill level. Conclusion: The effectiveness of the proposed method was verified by experiments. Users will be able to find the desired book without difficulty. This method can improve the quality of service and satisfaction of library use. Application: Our book search method can be applied as a book search tool in a real public library. We hope that the method can provide higher satisfaction to users.

In this paper, we propose a keyword query processing technique based on semantic relationships for OWL data. The proposed keyword query processing technique can improve user's search satisfaction by performing two types of associative search. The first associative search uses information inferred by the relationships between classes or properties during keyword query processing. And it supports to search all information resources that are either directly or indirectly related with query keywords by semantic relationships between information resources. The second associative search returns not only information resources related with query keywords but also values of properties of them. We design a storage schema and index structures to support the proposed technique. And we propose evaluation functions to rank retrieved information resources according to three criteria. Finally, we evaluate the validity and accuracy of the proposed technique through experiments. The proposed technique can be utilized in a variety of fields, such as paper retrieval and multimedia retrieval.

Linear constraint satisfaction optimization problem is a kind of combinatorial optimization problem involving linearly expressed objective function and complex constraints. Integer programming is known as a very effective technique for such problem but require very much time and memory until finding a suboptimal solution. In this paper, we propose a method to improve the search performance by integrating local search and integer programming. Basically, simple hill-climbing search, which is the simplest form of local search, is used to solve the given problem and integer programming is applied to generate a neighbor solution. In addition, constraint programming is used to generate an initial solution. Through the experimental results using N-Queens maximization problems, we confirmed that the proposed method can produce far better solutions than any other search methods.

The berth and crane scheduling problem in a container terminal encompasses the whole process of assigning berth to each ship, determining the duration of berthing, assigning container cranes to each ship, and determining the specific start and end time of each crane service, for all the ships scheduled to be arriving at the terminal during a certain scheduling horizon. This problem is basically a constraint satisfaction problem in which cranes and berths should be assigned in such a way that all the spatial and temporal constraints are satisfied without any interference. However, it is also an optimization problem because the requested arrival and departure time should be met for as many of the scheduled ships as possible, while the operation cost of the terminal should be minimized. In this paper, we present an effective and efficient approach to solving this type of problem, which combines constrain satisfaction search and heuristic repair. We first employ a constraint satisfaction search to find a feasib1e solution. Then, the feasible solution is modified to a more optimal one by iteratively applying our heuristic repair operations within the framework of constraint satisfaction search. Experimental results with a real data from Pusan East Container Terminal showed that our approach can derive a schedule of satisfactory quality in a very short time.

Since the World-Wide Web (WWW) has become a major channel for information delivery, information overload also has become a serious problem to the Internet users. Therefore, effective information searching is critical to the success of Internet services. We present an integrated search engine for searching relevant web pages on the WWW in a certain Internet domain. It supports a local search on the web sites. The spider obtains all of the web pages from the web sites through web links. It operates autonomously without any human supervision. We developed state transition diagram to control navigation and analyze link structure of each web site. We have implemented an integrated local search engine and it shows that a higher satisfaction is obtained. From the user evaluation, we also find that higher precision is obtained.

The purpose of this study was to identify the importance of salesperson selling behavior such as salesperson's orientation, similarity with customers and expertise as well as the relationship benefits of salesperson. A total of 400 questionnaires were distributed to adults in Daegu-Kyongbuk area and 335 questionnaires were collected(84%) and 314 samples were used for the statistical analysis. The primary methods of the statistical analysis were factor analysis, confirmatory factor analysis, correlation and path analysis using LISREL 8. The results are as follows: First, clothings salesperson's customer-orientation(p < .10), expertise, similarity (p< .10) and salesperson's functional, social benefits showed positive relation with customer satisfaction. And salesperson's selling-orientation influenced customer satisfaction of salesperson negatively. In addition customer satisfaction of salesperson showed positive relation with salesperson loyalty and satisfaction of the stores. Second, the salesperson loyalty showed positive relation with store loyalty and word-of-mouth but showed negative relation with post-purchase information search. Customer satisfaction of stores showed negative relation with post-purchase information search but no meaningful relation with store loyalty and word-of-mouth.

The goal of this study was to examine differences between traditional and electronic commerce in criteria of the amount of consumer information and the level of consumer satisfaction. In addition this study examined factors influencing the amounts of information search of consumers and the level of consumer satisfaction between traditional and electronic commerce. The results of this study are as follows. First, consumers gathered more information about stores and price in electronic commerce, but more information about quality and after service in traditional commerce. Second, overall, rational consumers, and consumers buying electronic goods collected more information. Third, consumers were more satisfied with shopping in electronic commerce than in traditional commerce except for the satisfaction from price. However, comsumers' satisfaction was not differed what kind of goods consumers buy. Fourth, if consumers gathered lots of information, they tend to be more satisfied than otherwise. In addition, there were positive relationship between consumer’lower age, rational purchase behavior, and positive thinking of the electronic commerce.

Considering the rapid growth of mobile industry and the emerging application marketing, this study focused on fashion applications, which had not drawn much academic attention before, and analysed relevant content composition, information-seeking benefits based on users' lifestyles and resulting differences in satisfaction and loyalty. In short, fashion applications were divided into fashion and non-fashion brand apps. Brand apps were subdivided into luxury, women's wear, men's wear, casual wear, sportswear, accessories and the like. Non-brand apps included commerce, magazine, information, style tip, SNS and wardrobe manager types. As for users' lifestyle-based information search, the higher the tendency to search information on the internet and to favour reasonable consumption, the more basic information on products and brands they sought, whereas the higher the tendency to look for high-profile brands and to favour global culture, the more additional information like images or entertainments they sought. To sum up, given that studies on fashion-specific applications were rare, the present study reviewed and categorized current fashion applications, and suggested theoretical and practical groundwork for developing content based on target consumers' lifestyle and for planning fashion applications in practice.
