In the context-aware system, rule-based AI technology has been used in the abstraction process for getting context information. However, the rules are complicated by the diversification of user requirements for the service and also data usage is increased. Therefore, there are some technical limitations to maintain rule-based models and to process unstructured data. To overcome these limitations, many studies have applied machine learning techniques to Context-aware systems. In order to utilize this machine learning-based model in the context-aware system, a management process of periodically injecting training data is required. In the previous study on the machine learning based context awareness system, a series of management processes such as the generation and provision of learning data for operating several machine learning models were considered, but the method was limited to the applied system. In this paper, we propose a training data generating method of a machine learning model to extend the machine learning based context-aware system. The proposed method define the training data generating model that can reflect the requirements of the machine learning models and generate the training data for each machine learning model. In the experiment, the training data generating model is defined based on the training data generating schema of the cardiac status analysis model for older in health status notification service, and the training data is generated by applying the model defined in the real environment of the software. In addition, it shows the process of comparing the accuracy by learning the training data generated in the machine learning model, and applied to verify the validity of the generated learning data.

This research is to find a direction of development through operating status survey of public library in Busan metropolitan city. First, Normally library users visit the library to check out books or to have a private study session. Also users normally obtained information about upcoming events done in the library through using offline search methods. Second, although the usage of the website was low, however the users demanded the increase in computer numbers in the library and online database for home access. Third, the users acknowledged the importance of the public library to their local community. Library policy indicator rated high in importance to the local community(m=3.86). However the reference desk(m=2.87), checkout desk(m=2.41), computer availability(m=2.47), as well as up-to-date artifact availability(m=2.64) did not reach the average point of 3.0. Thus, revealing that the public library's management policies were not sufficient enough to satisfy the needs of the library users.

The purpose of this study is to understand information behavior of older adults with diabetes. After reviewing previous research, related factors are identified and a questionnaire was devised. The structured interview was administered to the aged 60 and over in the B hospital (N=543). Data about awareness of the disease, health literacy, information environment, information need, information seeking, information use, information service, and personal background are collected and analyzed descriptively. Relationship between variables are examined and hypotheses are tested to find factors affecting information behavior. The level of the awareness of the disease and health literacy appeared to be low. It is proved that awareness of the disease is a factor affecting information need and information use. Health literacy affects information use. There is a statistical significant difference between information need and information use by disease education and duration. There is also a statistical significant difference between information use among groups divided by information environment, sex, age, and education. Based on the results, campaign to raise disease awareness, marketing promotion about information support facilities, customized information service for older adults are suggested.

BPEL is a standard executable language for specifying actions within business processes with Web services. BPEL workflow requires rule engine to describe application process in BPEL, as the requirements increase. It is needed to develop new BPEL's engine or modify BPEL's engine in order to add the functionality of rules to BPEL engines, but this method is not easy to implement and it requires very high cost. In this paper, we present an R4BPEL document, which uses the original BPEL grammar and includes a rule document. With this method, it is possible to build rule-based BPEL environment easily by adding web services with rules and R4BPEL document analyzer to the general-purpose Web services. In this paper, we campared a BPEL's document in proposed system with a BPEL's document in the existing system. And we demonstrated the simplicity of the rule-based system.
