The purpose of this study is to predict the usefulness and predictable effects of the use of dementia prevention games and dementia management applications provided in smart-phones for the elderly. First, 6 dementia diagnostic tools used to verify the effectiveness of the dementia prevention program were selected and the cognitive domains tested by each diagnostic tool were extracted. Second, 29 smart-phone dementia prevention game applications and dementia management applications were selected and the expected effects after using these applications were analyzed in connection with the cognitive domain extracted from the dementia diagnosis tool. As a result, it was expected that it would be helpful to manage dementia prevention by improving cognitive function in certain areas when playing games or managing dementia continuously using smart-phone dementia prevention applications. Smart-phone dementia prevention applications will be useful in improving the cognitive ability of the elderly and preventing dementia by supplementing the limitations of the dementia prevention program that is operated offline through time-space ease of use, continuous usability and economic feasibility.

Objective: The aim of this study is to find the optimal values of sliding factors which influence the mechanical emotion of users when they use sliding type mobile phones. Background: There are various researches that study the emotion of using mobile phones. They focus the correlation between emotion words and design factors and use the commercial products by the subjects in the experiment. However, it has a limit in finding the optimal point of emotional factors because we can search the restricted values in the mass production of the products. Therefore, we will find the optimal points by realizing the full range of the user's mechanical emotion. Method: First, we need to get the detailed factors which can describe the mechanical emotion in sliding up and down the mobile phone. Next, we find the control factors by considering the correlation between the factors of the sliding emotion and the possibility of quantitative design. To find the optimal points on the control factors, we make a sliding evaluation system which can help users feel the sliding mechanical emotion by realizing control factors. Finally, we find the optimal points by doing the experiment the system being used. Results: The critical values of the factors which are the main variables of this study are Open Max Force and Dead point Ratio. The optimal point of the Open Max Force is 200~250g/f, and the Dead point Ratio is 40~50%. Conclusion: In this study we develop the sliding evaluation system to realize the control factors of the sliding type phone and find the optimal values of the critical factors. Application: The results can be used as the criteria for designing sliding type phone.

To evaluate the status of the contact to lascivious computer programs and sexual attitude and behaviour by the grades of middle school boy students, the questionnaire survey was done on 715 students of five middle schools in Pusan and Kimhae area from December 15 to December 24, 1997. The data were analyzed by PC SAS; $X^2$ -test. The level of significance was 0.05. 404 students (56.5%) had a personal computer in their home. 516 students(72.2%) have experienced of using a computer program. 294(57%) of them usually played a game with computer. 514 students(71.9%) had experiences of the contact to a lascivious computer program, which increased with the grades of the students(p〈0.05). The first exposure to a lascivious program was when they were elementary school students in 24.6% of first grade middle school student, 13.8% of second grade, and 11.3% of 3rd grade students. 92% of the students was introduced to first contact through their friends. 63.7% of them watch the program at their friends home. The most common drives to contact to a lascivious programs were curiosity (53%). Sexual desire was a higher drive in third grade students (20.6%) than lower grades. After contacting to a computer lascivious program, desire of masterbation was more frequent in lower grade students. and feeling disgust was more frequent in higher grade students (p〈0.05). Frequence of masterbation or sexual intercourse was higher in high grade students(p〈0.05) In conclusion, distribution and popular use of computer attributes to the increased exposure to lascivious programs and lowering the age of first exposure. There was the difference according to the grades in the feeling and sexual behaviour after contacting to computer lascivious program. Appropriate methods to protect young students to contact a lascivious program should be sought. The use of computer should be educated in elementary school students accompanied by proper sex education.

Objectives: This study analyzed the factors that influence the mental health of adolescents in Korea, China, and Japan. Methods: The survey was conducted in each country between November 2008 and January 2009. The respondents were 1,390 Korean, Chinese, and Japanese students aged between 14 years and 16. The mental health was measured by the School Mental Health Scale of Ochanomizu University (2004), which is composed of six scales: physical symptoms, eating disorders, depression, interpersonal relationship, powerlessness, and impulsiveness. Results: The relationship with family and friends are strongly associated with mental health. As for Korean and Chinese female students experienced mental illness more than male. Regarding Korean students, the time to use TV computer game is related to relationship and impulsiveness. The mobile phone use more than three hours is related to depression and relationship for Japanese, and the number of family member less than three, is associated with powerlessness for Chinese. Conclusion: Regular and effective health education is required in order to improve students lifestyles and family and peer relationships. This study also offers the fundamental information for health promotion programs for Korean, Chinese and Japanese students.

In this paper, we address the challenging computer vision problem of obtaining a reliable facial expression analysis from a naturally interacting person. We propose a system that combines a 3D generic face model, 3D head tracking, and 2D tracker to track facial landmarks and recognize expressions. First, we extract facial landmarks from a neutral frontal face, and then we deform a 3D generic face to fit the input face. Next, we use our real-time 3D head tracking module to track a person's head in 3D and predict facial landmark positions in 2D using the projection from the updated 3D face model. Finally, we use tracked 2D landmarks to update the 3D landmarks. This integrated tracking loop enables efficient tracking of the non-rigid parts of a face in the presence of large 3D head motion. We conducted experiments for facial expression recognition using both framebased and sequence-based approaches. Our method provides a 75.9% recognition rate in 8 subjects with 7 key expressions. Our approach provides a considerable step forward toward new applications including human-computer interactions, behavioral science, robotics, and game applications.

As application development environment changes rapidly, importance of user interface design is increasing. Usually, most of designers are clustering by subjective method of individual to define objects that have relativity in design interface. But, interface which is designed without particular rules just adds inefficiency and complexity of business to user who use this system. Therefore, in this paper, we propose an object oriented design model that allows for flexible development by formalizing the user interface prototype in any GUI environment. The visual cohesion of the user interface is a new set of criteria which has been studied in relation to the user interface contents, and is founded on the basis of the cohesion of the interface as defined using basic software engineering concepts. The visual cohesion includes the issue of how each unit is arranged and grouped, as well as the cohesion of the business events which appear in the programming unit. The interface will become easier to understand and use if the business events are grouped by their inter-relevance within the user interface.

The topic of this study is a survey research about the economic recognition related to economic ethics and information literacy of students(6,779) extend from elementary school to university. First, for the ability to use computers, it is recognizing that 49.6% of students are normal, 38.6% are superior, and 12.8% are inferior. In part of class, it tends to recognize that it is the superior as the level of school is the lower excepting middle school students. Second, we can find great difference between male students and female students related to purpose of using internet, 79.8% of male students are using computer to play game or entertainment(1), search data or knowledge(2), chatting or massenger(3), 70.1% of female students are using internet to search data or knowledge(1), chatting or massenger(2) and meeting of similar taste. Third, it shows a tendency that the economic activity using internet or cell-phone increases faster as the level of schools is higher. In detail, they primarily use buying or settlement of products(63%), purchasing internet service(20.9%). Fourth, for using illegal CD, not only they didn't feel guilty in all levels of schools, excepting university students, it is showed that the trust of intellectual poverty right is weaker as the level of schools is higher. So, it is becoming serious problems. It seems a task which should be supplemented through economic education of schools in the future.
