One of the most frequent uses of Internet is data gathering. Data can be about many themes but perhaps one of the most demanded fields is the tourist information. Normally, databases that support these systems are maintained manually. However, there is other approach, that is, to extract data automatically, for instance, from textual public information existing in the Web. This approach consists of extracting data from textual sources(public or not) and to serve them totally or partially to the user in the form that he/she wants. The obtained data can maintain automatically databases that support different systems as WAP mobile telephones, or commercial systems accessed by Natural Language Interfaces and others. This process has three main actors. The first is the information itself that is present in a particular context. The second is the information supplier (extracting data from the existing information) and the third is the user or information searcher. This added value chain reuse and give value to existing data even in the case that these data were not tough for the last use by the use of the described technology. The main advantage of this approach is that it makes independent the information source from the information user. This means that the original information belongs to a particular context, not necessarily the context of the user. This paper will describe the application based on this approach developed by the authors in the FLEX EXPRIT IV n$^{\circ}$EP29158 in the Work-package "Knowledge Extraction & Data mining"where the information captured from digital newspapers is extracted and reused in tourist information context.

With the emergence of pervasive computing, personalization becomes an important issue to provide with users customized services, anywhere and anytime in their specific environment. Many researches have shown the possibilities of personalization by acquiring and processing sensor information around users. However, personalization remains still at its infancy, since most researches have failed to consider various contexts comprehensively besides sensor data, and just developed tailored services for a specific application domain. In this work, we propose a simulation-based CAS (context Aware Web Services) development methodology. Our methodology considers various contexts on users (eg. current location), web services (eg. response time), devices (eg. availability) and environment (eg. sensor data) all together by simulating them on the fly for personalized and adaptable services.

Social network service is service that enables the human network to be built up on web. It is important to record users' information simply and establish the network with people based on the information to provide with the social network service effectively. But it is very troublesome work for the user to input his or her own information on the mobile environment. In this paper we suggested a system which classifies users' behavior using context and creates blogging sentences automatically after inferring the destination. For this, users' behavior is classified and the destination is inferred with the sequence matching method using Naive Bayes classification. Then sentences which are suitable for situation is created by arranging the processed context using the structure of 5W1H. The system was evaluated satisfaction degree by comparing the created sentences based on actually collected data with users' intension and got accuracy rate of 88.73%.

The purpose of this study is to investigate the interaction effects of organizational context, customer reaction, and job burnout in Senior Welfare organizations. In addition, we will analyze the moderating effects of demographic characteristics (personal characteristics, organizational characteristics). A total of 796 social workers engaged in Senior Welfare projects were analyzed. As a result, the following results were obtained. First. It was found that there was a significant difference between the variables in the sociodemographic characteristics, organizational context, customer reactions, and interaction effects on job burnout. Second, age, employment type, and Social Worker qualifications were the most important variables of control effect. The specific organizational behavioral factors between the employees and the users should be studied.

In the paper, we proposed an IM-ACM(Insider Misuse-Access Control Model) for preventing illegal information leakage by insider who exploits his legal rights in the ubiquitous computing environment. The IM-ACM can monitor whether insider uses data rightly using misuse monitor add to CA-TRBAC(Context Aware-Task Role Based Access Control) which permits access authorization according to user role, context role, task and entity's security attributes. It is difficult to prevent information leakage by insider because of access to legal rights, a wealth of knowledge about the system. The IM-ACM can prevent the information flow between objects which have the different security levels using context role and security attributes and prevent an insider misuse by misuse monitor which comparing an insider actual processing behavior to an insider possible work process pattern drawing on the current defined profile of insider's process.

The purpose of this study was to investigate middle school students' processes of argumentation in science lessons and to compare students' argumentation in different contexts (socioscientific context/scientific context). An argumentation-based teaching-learning strategy was used to enhance quality in students' arguments in science lessons. Data were collected from five lessons by video- and audio-recording eight groups of four students each engaging in argumentation. The quality and frequency of students' argumentation was analyzed using an assessment framework based on the work of Toulmin. The findings showed that: (a) there was improvement in the quality of students' argumentation; (b) there were no differences in the structure of argumentation and percentage of explanatory argumentation components as well as dialogic argumentation components in different argumentation contexts. The results of this study showed that students' argumentation can be enhanced with strategic argumentation teaching-learning.

This study reviews a family-friendly system of companies from the viewpoint of family resource management. The concept of a family-friendly system in the workplace means that the strategy 'supports the family' or 'is sensitive to the family life' and recognizes a need for balance between work and family. The suggestions proposed in this study were as follows: First, the direction of a family-friendly system must reflect the needs of the family members positively and recognize diversity. Second, it must consider efficient methods relating to the matter of the gender because a corporate culture enabling men to use childcare leave has not grown, even in family companies. Third, the directions to check the present developing process of our society and to develop the suitable way to each company must be shown. This study has proposed that the subjects must solve immediately in the future with understanding the contents and looking around the status of the enforcement at the inside and outside of the country for a family-friendly system to handle the balance between work and family in the workplace. The problems were the context of the introductions and the results of balancing between work and family no matter whether the introduction of the system by company or not.

The purpose of this study is to examine the effects of authentic leadership on employee job satisfaction as well as the mediating role of motivation in the relationship between these two variables. Prior literature on authentic leadership have repeatedly argued that authentic leadership is not simply the ethically "right" thing to do, but also can effectively boost firm performance by increasing employees' job satisfaction and motivation. This study investigates whether the proposition is supported by empirical evidence in the context of Korean companies. Survey data were collected from 230 employees from several companies in South Korea. The results show that authentic leadership has a positive effect on employees' job satisfaction. As to the effects of authentic leadership and work motivation, authentic leadership turns out to have a positive effect on both extrinsic and intrinsic work motivation. The study also confirmed partial mediating effect of job satisfaction in the relationship between authentic leadership and job satisfaction.
