With the development of ubiquitous computing and the construction of infrastructure for one-to-one personalized services, the importance of context-aware services based on user's situation and environment is being spotlighted. The smart home technology connects real space and virtual space, and converts situations in reality into information in a virtual space, and provides user-oriented intelligent services using this information. In this paper, we proposed the discovery of the behavior sequence pattern using the mining in the smart home. We discovered the behavior sequence pattern by using mining to add time variation to the association rule between locations that occur in location transactions. We can predict the path or behavior of user according to the recognized time sequence and provide services accordingly. To evaluate the performance of behavior consequence pattern using mining, we conducted sample t-tests so as to verify usefulness. This evaluation found that the difference of satisfaction by service was statistically meaningful, and showed high satisfaction.

In this study, a weighted fuzzy min-max (WFMM) neural network model for pattern classification is proposed. The model has a modified structure of FMM neural network in which the weight concept is added to represent the frequency factor of feature values in a learning data set. First we present in this paper a new activation function of the network which is defined as a hyperbox membership function. Then we introduce a new learning algorithm for the model that consists of three kinds of processes: hyperbox creation/expansion, hyperbox overlap test, and hyperbox contraction. A weight adaptation rule considering the frequency factors is defined for the learning process. Finally we describe a feature analysis technique using the proposed model. Four kinds of relevance factors among feature values, feature types, hyperboxes and patterns classes are proposed to analyze relative importance of each feature in a given problem. Two types of practical applications, Fisher's Iris data and Cleveland medical data, have been used for the experiments. Through the experimental results, the effectiveness of the proposed method is discussed.

There are rule-based learning method and statistic based learning method and so on which represent learning method for hierarchy relation between domain term. In this paper, we propose to leveling and similarity measure using the extended AHP of fuzzy term in Information system. In the proposed method, we extract fuzzy term in document and categorize ontology structure about it and level priority of fuzzy term using the extended AHP for specificity of fuzzy term. the extended AHP integrates multiple decision-maker for weighted value and relative importance of fuzzy term. and compute semantic similarity of fuzzy term using min operation of fuzzy set, dice's coefficient and Min+dice's coefficient method. and determine final alternative fuzzy term. after that compare with three similarity measure. we can see the fact that the proposed method is more definite than classification performance of the conventional methods and will apply in Natural language processing field.

Sea casualties may happen in ship, cargo and the others concerned with sea transportation. : the shipo-wer, marine insurer and salvage company have been endeavored to compensate salvage award with some rule and regulation such as Marine Insurance Act, York Antwerp Rules and Average adjustment rules. Once sea casualties happened, the salvage contract is established between the owners, marine insurance and salvage company, the contract are divided into so many kinds of them. In this paper, we have an analysis on the character of the salvage contract whether the characteristic contents of them are in benefit to any party or not. In this connection with these positive or negative character of the contract, it is worthwhile to compare the actual salvage expenses contract with no cure no pay contract. LOF 1990 has been revised recently, which is based on no cure no pay, expecially, the special compensation, safety net clause of LOF 1990 could be understood in the view of the prevention of sea pollution and the preservation of sea circumstances in the world. Salvage has the complicated and quality, because the adjustment of almost salvage charges have been treated through the other sea casualties which is accompanied by and mixed with. Besides of the importance of salvage contracts, we are in need to understand that what the diversified character of salvage charges are. Furthermore the owners should carefully select the insured conditions on Hull Insurance according to the type of his company, operating ocean route, loading cargo and etc. In this paper, we would try to analyze the character of the salvage award such as General Average, Sue and Labour Charges and Particular charges. We would like to propose that the uniformed system of the salvage award. Compensation should be built up for the effective and efficient salvage operation and for reducing the claims and conflicts from the concerned parties. To this end, we could expect that the uniformed system for salvage award compensation will come to be the benefit of all owners, insurers, salvage company.

Casual games are often have simple rule and easy to play. Like Angry birds, players can sling a bird as a bomb to destroy target. But the film adaption encounters numerous questions. games in pursuit of strong sensed presence, pay attention to experience; film stress the integrity of the story, attaches great importance to plot. However, casual games don't have story and plot. This paper take angry birds as example, analyzes the difficulties and method of adaptation from leisure mobile games to films, summarizes the key successful elements of adaption, such as subdivided the target group, chose an appropriate genre, write a script follow the basic logic and frame of film, set contradiction, complicated the character and still contain key elements of the game, in order to provide new ideas in the future development of integration of game and movie industry.

The service loads are often decisive in the design of concrete structures. The evaluation of the cracking moment, $M_{cr}$, is an important issue to predict the performance of the structure, such as, the deflections of the reinforced concrete beams and slabs. To neglect the steel bars of the section is a simplification that is normally used in the computation of the cracking moment. Such simplification leads to small errors in the value of this moment (typically less than 20%). However, these small errors can conduce to significant errors when the values of deflections need to be computed from $M_{cr}$. The article shows that an error of 10% on the evaluation of $M_{cr}$ can lead to errors over 100% in the deformation values. When the deformation of the structure is the decisive design parameter, the exact computing of the cracking moment is obviously very important. Such rigorous computing might lead to important savings in the cost of the structure. With this article the authors wish to draw the attention of the technical community to this fact. A simple equation to evaluate the cracking moment, $M_{cr}$, is proposed for a rectangular cross-section. This equation leads to cracking moments higher than those obtained by neglecting the reinforcement bars and is a simple rule that can be included in Eurocode 2. To verify the accuracy of the developed model, the results of the proposed equation was compared with a rigorous computational procedure. The proposed equation corresponds to a good agreement when compared with the previous approach and, therefore, this model can be used as a practical aid for calculating an accurate value of the cracking moment.

The purpose of this study was to examine the stressors, coping styles, communication with mother, school adaptation and predictors for school adaptation. The subjects of this study consisted of 354 children. They were 6th grade of elementary school in Taegu city. The periods of study was from march 10, to march 18, 2000. Data were analyzed by SAS computer programme. The results of this study were as follows: 1. The mean score for stressor was 39.91 in children(range 24-72). The higher stressor among three subgroups of stressor was mass media stressor. The degree of stressor revealed to be influenced significantly economic status. 2. The most frequently used coping style was problem-oriented coping style(M=18.94) in children. The degree of emotion-oriented coping style revealed to be influenced significantly family's atmosphere 3. The mean score for communication with mother was 72,44 in children(range 20- 100). The degree of communication with mother revealed to be influenced significantly sex, economic status, family' atmosphere. 4. The mean score for school adaptation was 62.48 in children(range 25-100). The higher school adaptation among five subgroup was rule dimension. The degree of school adaptation revealed to be influenced significantly sex, birth, mother's job, economic status, family's atmosphere. 5. School adaptation were positively correlated with communication with mother, problem- oriented coping style(r=0.40 p<0.001) (r=0.30 p<0.001). 6. School adaptation were negatively correlated with emotion-oriented coping style, stressor (r=-0.16 p<0.01)(r=-0.13 p<0.01). 7. Forward multiple regression analysis revealed that the most powerful predictor was the variable communication with mother accounted for 15.25% in school adaptation. All variables accounted for 25.55% in school adaptation. From the above results, it can be concluded that teaching mother about importance of communication, encouraging to use problem-oriented coping style is necessary to improve school adaptation in 6th grade elementary school children

The purpose of this study was to examine the features that make residents feel “at home” in ALFs in Southwest Virginia and to suggest further policy and design guidelines for better Quality of ALFs as a “home.” For this purpose, residents' needs, experiences, and opinions of the physical environment, the social environment, and the organizational environments such as policies and programs of ALFs were identified. As a multi-case study, five ALFs in Southwest Virginia were studied using constant comparative methos of data analysis. In addition to face-to-face interviews with 25 residents and five administrators of five ALFs, observations were conducted with personal journal. Overall, the five sites selected presented homelike features showing the philosophy of assisted living which combines housing and services. Each facility was designed to be a single-family house or multi-family dwelling in outside appearance. As a whole, residents felt isolation and loneliness and they did not have active interaction with other residents because of diverse background among the residents. However, all of them had close relationships with the staff. The staff's attitude and behavior seemed to influence greatly the residents' feeling “at home.” Despite the provision of diverse activities by the facilities, many residents did not participate in the programs. Most of the residents agreed that the rule and regulations were fair. In spite of high satisfaction with the facility, many people did not think of their current dwelling as a real ‘home.’ As the biggest difference between living in their own homes and living in the ALF, people pointed out a lack of independence, freedom, and autonomy. Residents of ALFs may have reordered their priorities in their current life situation so that safety, security, and care were more important to them than feeling “at home.” Among the three factors --physical, social, and organizational-- that affect the residents' perception of ALFs as a “home, ” many emphasized the importance of social factors such as relationships with the staff and residents, and social support from their family or friends.

Importance of XML as a target of Data Mining is growing because XML is used generally as a standard markup language for describing structured data. Especially researches have been done about extracting wanted informations by applying association rules to XML documents. But there are few development about solving the problems of method for efficiently obtaining informations from similar kinds of XML documents. To solve the problem this paper tries to suggest the method by which common XML structure is extracted form the same kinds of XML documents having a various XML schemas. The resulted schema structure is supposed to be important one as a preliminary job because it helps us to acquire the useful informations from various kinds of documents by unifying their structures.

Recently, in the whole fields of industry including shipping business, the conception and importance of Human Factor is very highly and frequently emphasized. But the domestic crew disaster including injury and illness in our shipping business shows higher accident rate than other shipping countries. Therefore the developing of measures to prevent/reduce the accident is highly required as the marine accident including crew disaster causes enormous loss of property and human life in size and scale. But, because the domestic data regarding the crew accident are relatively insufficient and rule, the developing of those measures has many difficulties. Therefore, this study is to make the concerning data for the useful reference by showing the trend and current situation of crew accidents, assorted by the crew's rank, type of the accident, injured part of the body, cause of the accident, type of ships and type of the works when the accident occurred, by using the each ocean-going shipping company's recent 5 years('95∼'99) data in korea.
