Virtual Reality simulation enables immersive 3D experience of a Virtual Environment. A simulation-based VE can be used to map real world phenomena into virtual experience. This research studies on the use of Newton's physics law to demonstrate the effects of forces upon object's falling movement, and their effects towards other fallible objects. A reconfigurable simulation enables users to reconfigure the parameters of the objects involved in the simulation, so that they can see different effects from the different configurations, such as force magnitude and distance between objects. This concept is suitable for a classroom learning of physics law. Preliminary implementation is done on a PC with a joystick for 4DOF movement. The graphics is implemented by SGI OpenGL Performer. A middleware called NAVERLib that consists of Performer's modules for easy XML-based configuration is used for management of visualization, network and devices connection, and where the engine of this domino simulation is attached.

This study proposed an expanded technology acceptance model (TAM) incorporating perceived fee (PFE) and perceived enjoyment into the original TAM We examined that the extended TAM provides supplementary information about behavior intentions (BI) toward mobile data services (MDS). This study also investigated some significant differences in the relative influence of the determinants of BI toward MDS depending on experience. The extended TAM was empirically evaluated by using survey data collected from 149 inexperienced users and 393 experienced users. The findings indicated that PFE is the strongest determinant of BI toward MDS, and the antecedents leading to users' BI vary over time. The results may provide further insights into MDS practitioners and marketing managers.

E.F(Experience Factory)는 지속적인 프로세스 개선을 위하여 도입된 패러다임으로서 1970년대 미국의 USC/UMD와 NASA/GFSC 등에서 추진되었으며 지금은 여러기업으로 확산 및 적용되고 있다. 이 방법론의 특징은 재사용 가능한 프로젝트 정보 및 프로세스 속성을 데이터베이스로 구축하여, 외부개선모델의 도입없이 자체적인 반복활동으로 프로세스 개선이 가능하다는데 있다. 국내 기업들은 프로세스 개선활동을 수행하고 있으나 아직까지 E.F 구축을 위한 사례는 보고된 바가 없다. 본 논문에서는 이러한 국내실정을 감안한 E.F 프레임워크의 구축방안에 대하여 논하고자 한다.

This study was conducted to identify students' meaningful scientific experiences and to ascertain the path through which the experience led to learning. The subjects of 'Understanding of the History of Science' were asked to write an essay on the subject of 'Effects of science on my life' to 81 students in the department of literature and 125 students in the science department. After that Classification criteria were established through scientific experts' seminars, and the scientific experiences that affected students and their effects were examined. The results from analyses were summarized as follows: First, As a result of study about Science Education experience that has impacted students' lives, the students were influenced by images, most of which were influenced by scientific videos. They were also influenced by science classes and science books. As a result of classifying science experience, most of the experience is composed of Informal Science Learning. Second, as a result of examining how students were influenced by their scientific experience, they found that they were affected by their daily life or influenced by science. As a result of the research, it can be confirmed that Informal Science Learning experience is an important learning form that has a great influence on students. Therefore, appropriate Informal Science Learning experience should be introduced into the class, and research and development on the Informal Science Learning experience preferred by the students should be done.

Recently, Korea's interest in environment protection is increasingly growing, and Korea realizes the seriousness of environmental pollution and national movement to minimize the effect is arising. As part of the movement, the need of environmental education in elementary schools is on the rise. This study aims to develop integrated environmental experience programs allowing students to have experience activities in forests, rivers, and seas that they can approach easily around them and to have environmental education through various plays. In addition, the study purposes to compare general educational education programs in actual education in terms of the effect of the program on students' environment attitudes. This study was conducted to 50 fourth graders in two classes of S elementary school in Busan, and the 25-student comparative group had the normal educational education program that is mostly being performed in actual education while the 25-student treatment group had the survey on environmental attitude after a class using an integrated environmental experience program. The survey content is about environmental attitudes, and it consists of six subjects such as general environment, environmental pollution, energy, water resources, recycling, and animal protection and has 7 or 8 items by each subject which is divided into eight sub-items including sensibility, belief, values, spontaneity, criticism, patience, attention and interest. The findings are as follows. First, the integrated environmental experience program has a more positive effect on environmental attitudes than the general educational program. In particular, it is really effective about the topic of animal protection among students' environmental attitudes. Second, the integrated environmental experience program has a more positive effect on values and interests than the general environmental education program.

Background: Job satisfaction of dental hygienists has been discussed continuously in dental hygiene research. It has been the most representative performance variable in dental and human resource management. However, in quantitative research, most of the studies have analyzed the causal relationship with variables related to dental hygienists' job satisfaction. The existing qualitative research contains only the studies that targeted dental hygienists with an experience of more than 10 years. The present study aimed to understand and to characterize the job satisfaction of dental hygienists with an experience of 2 to 10 years and to compare it with the qualitative research on dental hygienists with an experience of 10 or more years. Methods: An in-depth interview of dental hygienists with 2 to 10 years of experience working in 10 dental clinics was conducted. For data analysis, Giorgi's analysis method was used. Results: After analyzing the meaning of job satisfaction of dental hygienists, 180 semantic words and 19 subcategories were derived. The results of the interview were categorized into for central meanings: recognition and rewards, work experience and ability improvement, occupational characteristics, and work characteristics. Recognition and rewards included workplace recognition, patient recognition, self-effort and recognition, and the feeling of being rewarded. Work experience and ability improvement included various work experiences and factors relates to improving the work ability. Occupational characteristics included professional job, interest and persistence, job extensibility, and no burden of employment. Work characteristics included working conditions and separation of work and private life. Conclusion: The development of tools to measure the level of dental hygienists' job satisfaction after long-term service and to conduct follow-up research regarding ways and effects to improve job satisfaction is needed.

Purpose: This study aims to identify changing image of nurse before and after the first clinical experience, and before graduate. Method: The subjects were 69 nursing students. All of them had their first clinical experience for 1 week during sophomore year. The Nurse's Image was measured before and after the 1st clinical experience, and before graduation. Collected data were analyzed by using repeated measure ANOVA and pair wise comparison method. Results: 1. The mean score for the Nurse's Image overall held by after 1st clinical experience($3.78{\pm}.38$) was more positive than those held by before graduation($3.50{\pm}.49$) and before 1st clinical experience($3.35{\pm}.36$). 2. For the four subscales (F=25.673 p= .000), the mean score of traditional(F=10.394 P= .000), Social(F=11.673 P= .000), Professional(F=17.341 P= .000) and personal Image(F=19.463 P= .000) were more positive than before graduation and before 1st clinical experience. Conclusion: Summarizing, after the nursing students had their 1st clinical training, the nurse's image perceived by them was positively improved compared to before the training. However, by the time of graduation the improved nurse's image was declined back. Therefore it is necessary to develop proper out-to field training program that will help to maintain and furthermore improve nurse's image.
