Due to the rapid development of information & communication technology under high performance computing environments, the multimedia production techniques have been applied to a variety of multimedia fields such as general banner advertisements including texts, images and animations, and the internet-broadcasting dealing with videos and sounds. This paper presents an authoring tool with main functions to setup events objects (image, animation, sound, button, area) and to setup action functions, so that non-experts can easily produce multimedia including images, sounds, animations and so on. The authoring tool implemented in Java can be applied to the CD-ROM title production as well as the web-site construction. We can expect that when this authoring tool is used for in multimedia production, both cost and time will be reduced due to its convenience and powerful functions. We have a future plan to integrate intelligent multimedia presentation techniques with the presented tool for the autonomous multimedia authoring works.

As the use of mobile device is popularized, the needs of variable services of WiMAX technique and the importance of security is increasing. There is a problem that can be easily attacked from a malicious attack because the action is achieved connectionlessly between neighbor link establishing procedure and TEK exchange procedure in mobile WiMAX even though typical 1 hop network security technique is adapted to WiMAX for satisfying these security requirement. In this paper, security connected mechanism which safely connects neighbor link establishing procedure of WiMAX and TEK exchange procedure additional to the basic function provided by IEEE 802.16e standard to satisfy security requirement of mobile WiMAX is proposed. The proposed mechanism strengthens the function of security about SS and BS by application random number and private value which generated by SS and BS to public key of neighbor link establishing procedure and TEK exchange procedure. Also, we can prevent from inside attack like man-in-the-middle which can occur in the request of TEK through cryptographic connection of neighbor link establishing procedure and TEK exchange procedure.

WebDAV is a protocol to support collaboration among one or more groups in geographically distant locations through the internet. WebDAV extends the web communication protocol HTTP/1.1 to provide a standard infrastructure for .supporting asynchronous collaboration for various contents across the internet. A WebDAV client uses HTTP requests to perform a renewal and update action to the resources in WebDAY servers. So, it is desirable that the client supports the ability of authoring and version management with a good concurrency control and property management. In this paper, to enhance usability, we developed a .NET-based WebDAV client with a user interface similar to the Windows Explorer. The developed WebDAV client supports easy launching of the authoring application and appropriate lock control for the server resources. In addition, through the functionality of process monitoring, it supports automatic update of the server resources when the modification of the resources are completed by the user. The WebDAY client is a .NET-based application written in the C＃ language, running on any platform supporting a .NET framework.

The purpose of this study was to examine female consumers' attitudes and purchase intentions toward intimate apparel brands. To understand female consumers' shopping behaviors for intimate apparel products, this study examined interrelationships among brand familiarity, perceived risk, attitudes, and purchase intentions toward intimate apparel brands. A conceptual model was developed by adopting perceived risk theory (Cox, 1967) and theory of reasoned action (Ajzen & Fishbein, 1980). A pre-survey using a paper and pencil was conducted to identify the most familiar intimate apparel brand to young female consumers. The majority of pre-survey respondents (66 female college students) indicated Victoria's Secret as the most prominent intimate apparel brand. Therefore, Victoria's Secret was used to examine possible effects of brand familiarity on perceived risk and attitudinal and behavioral responses toward the brand. Using a web-based survey, 384 complete responses were collected from young female college students between the ages of 18-29 at a Mid-southern U.S. university. A structural equation modeling was employed to test the proposed research model and hypotheses. Results showed positive, statistically significant associations among the four variables (e.g., brand familiarity, perceived risk, attitudes, and purchase intentions). The findings suggested that young female consumers who are familiar with a particular intimate apparel brand are likely to perceive a low level of risk, leading to positive, strong attitudes with purchase intentions toward that particular intimate apparel brand. This suggests establishing brand familiarity through integrated marketing communication is crucial for risk reduction strategy in intimate apparel shopping.

This study was conducted to investigate the concern of the primary school teachers and the teaching situation about the environmental education through questionnaire survey on the effective environmental education. The results of questionnaire were analysed and discussed to provide the effective teaching method for the environmental education. The result of this study is as follows. 1. It was found that teachers want to teach environmental lessons as a special subject, and the content of the environmental lessons in textbook was not enough in quantity, the living waste was the most serious ploblem. Owing to the lacking in materials for the lectures on environmental education, most teachers collect the material depending on the mass communication. Also they were more interested in the environmental lessons rather than the other lessons in textbook. But because of the lacking in administrative assistance, they have difficulty in conducting the effective environmental education. 2. The teaching method of the environmental education in most primary schools was a all together-type lecture in classroom. Owing to conducting the environmental education for the knowledge than the action through the extra activity, it was difficult to expect the effect of the environmental education. Also the rate of using the reflection materials which can be improved the studying effect was very low. 3. For the effective environmental education most teachers wanted the spot learnings and the case studies and teacher education and training to get an special knowledge for environmental education. The effective evaluation method for children's environmental education is to present the results by environmental experiences and practices and to formulate a system education is organized for the effective management and activation of environmental education. 4. By practising the seasonal spot learnings, students need to change of learning method and to realize the importance of environment through own self-experiences. 5. In the future, it is desirable that researching of an environmental education is offered the effective practising teaching method which is improving the development of customs and functions, cultivation of the sense of value, ability to solve the problem, to determine the intention as well as the survey on the real situation and the consciousness about environmental education.

Objectives: Promotion of food safety/eradicating adulterated food has been listed as one of the four major issues recently identified for action by the Korean government. Due to the related seriousness, the food industry has been encouraged to take steps to restore consumer confidence. In order to set guidelines for the creation of manuals for the response to a food safety crisis by the food industry, this study provided a suggested organization for a crisis response team and operating procedures for crisis response activities. Methods: The prototypes of an organizational structure and a set of standard procedures for a crisis response system were provided. Results: The results of the study suggested that a crisis response team should be comprised of four divisions of responsibility: information analysis, site response, communication and operational support. The organization chart and the role and functions for each division of the crisis response team should be indicated. Response activities will be more effective when the team features multi-disciplined staffing, such as public relations, food safety/technology/quality, sales/marketing, purchasing, production, distribution/logistics, regulatory affairs/legal, and consumer service specialists. This study created a flow chart for the total crisis response system, which included crisis and normal situations. A crisis response team should be continuously operated for both crisis and normal conditions. This study also suggested a scenario to explain the procedures for crisis response activities. Conclusion: In order to cope more effectively with a food safety crisis, the organizational structure and its functions should be defined clearly, and a detailed set of standard procedures for response activities should be offered.

This study analyzed the consequences of using a company's own letter type for the brand image. After evaluating the brand image of companies that have their own letter types, the study concluded that the fact a company has its own letter type works positively for the brand image. In addition, the survey respondents see the corporate activity for developing letter types as an action for the public interest, and they agree with an argument that each company' own letter type can symbolize the company as CI. By studying literatures in the field of cognitive science, the study indicates that for communication through the letter type with consumers, companies should be careful when choosing their specific letter types and that repetitive exposure to a letter type helps people recognize it through a human experiment.

Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user-centered design methodology which uses the influential factors on the interactivity. This research is the first one of three linked- studies and categorizes the three main factors on the interactivity-Interface /Intersubject/Interaction. 'Interface' is the field for the interactivity. It will be the main subject for the second study. 'Intersubject' is the performer for the interactivity. Its specific attributes are analyzed in terms of user's needs for interactivity and six subdivisions are analyzed-functional & artistic need /external & subconscious need/info-communication & sympathy need. 'Interaction' is the performance for the interactivity. Its specific attributes are discussed in terms of behavioral interactive process and again sixsub-steps are analyzed-junction/immersion/ mental model/action/transformation/neo-experience.

Addiction can be largely divided into two categories. One is called medium addiction in which medium itself causes an addiction. Another is called cause addiction that brings addiction through combination of sensitive self and latent personal action. The medium addiction involves addiction phenomena directly caused by illegal drugs, alcohol and various other chemicals. The cause addiction is dependent on personal sensitivities as a sensitive problem of personal and includes cyber addictions such as shopping, work, game, internet, TV, and gambling. In this paper we propose two-dimensional addiction model that are equivalent to using an R-L-C series circuit of Electrical circuit and a Spring-Damper-mass of mechanical system. We also organize a Duffing equation that is added a nonlinear term in the proposed two-dimensional addiction model. We represent periodic motion and chaotic motion as time series and phase portrait according to parameter's variation. We confirm that among parameters chaotic motion had addicted state and periodic motion caused by change in control coefficient had pre-addiction state.

In this paper, we proposed a contents of Chinese characters learning based on gesture recognition using HMM(hidden markov model) algorithm. Input image of the system is obtained in 3-dimensional information from the TOF camera, and the method of gesture recognition is consisted of part of forecasting user's posture in two infrared images and part of recognizing gestures from continuous poses. In the communication between human and computer, this system provided convenience that user can manipulate it easily by not using any further equipment but action. Because this system raise immersion and interest by using two large display and various multimedia factor, it can maximize information transmission. The edutainment Chinese character contents proposed in this paper provide educational effect that use can master Chinese character naturally with interest, and it can be expected a synergy effect via content experience because it is based on gesture recognition.
