In the paper, we develop the ‘Navigation Mechanism’ that can present the 3D space and trace the location in the user's viewpoint. Especially, using this mechanism, VRML tools are used to develop the virtual reality space in the internet. These mechanism can effectively represent the 3D virtual reality space and apply the many 3D related parts like architefure, education, entertainment and so on.

Recently maritime colleges in Korea have confronted with many difficulties on account of changes of educational circumstance such as increasing the number of low-wage foreign officers on board Korea-registered vessels, weakening international competitive power, avoiding reaction in the field of 3D occupational category etc. Therefore, We are drawing up a efficient educational system cultivating the well-trained marine officers who will take a more active role in the ear of 21C marine revolution The questionnaire was composed of 5 courses-entrance into a school, classwork, campus life, on-board training, choosing occupations and conducted the questionnaire survey of students in Maritime College in Korea Maritime University. And the analysis was carried out to understand the changes of student's consciousness structure and find out the problems of current maritime education system.

In this paper, we have studied the deformation problem of the scaffold caused by the FDM type 3D printer. The DOE (Design of experiment) and 3SC was used to solve the deformation problem of the scaffold generated from the adhesion surface between the scaffold and the bed. The methodology was used to derive the solution and the experiment was conducted on the derived solution. As a result of evaluating the experimental results obtained for the solution, it was found that the deformation of the scaffold was much improved. By using the DOE, We were possible to derive the output condition of scaffold.

This study purposes to suggest a next generation research and education environment which is possible by the linkage of two sectors based on cyberinfrastructure. It is to design a new research-education linkage system which can apply the results of R&D to the higher education in natural science and engineering areas. literatures were reviewed on new paradigms of R&D triggered by the advent of cyberinfrastrcuture. A couple of overseas and domestic cases of such paradigm were introduced. With the backgrounds of case studies and theoretical models, a new research-education linkage environment system was suggested. Specially e-AIRS system was introduced as an example of new model in Korea. In addition, some policy issues were discussed as related to the successful promotion of such programs.

This study was conducted to show one case model for a community nutrition program as a part of the public health systems. The purpose of this study is to evaluate the effect of the nutrition education through the Knowledge(K), Attitude(A), and Practice of the nutrition that is the Behavior-Diagnosis(Be-D). The Nutrition Education was done for 33 housewives whom live in Sudong-Myeun, Namyangju-Kun, Kyungki-Do. It had been performed eight times during April 3rd through May 30th, 1991. We investigated actual conditions of objects about K, A, Be-D in the nutrition, and the Food Environment(En) separately before and after the nutrition education by questionnaire and interview. The results of the research turned out as follows ; 1. The comparison of the scores before and after nutrition education showed significant increase in the knowledge and attitude. 2. The scores of the Be-D were also significantly higher after education, especially in the number of foods taken per day, the balanced diet, the general food habits for adult, and amounts of intake of nutrients showed significant increase of lipid, calcium, Vit. A, $Vit B_2$, Vit. C after nutrition education. 3. Multiple regression analysis showed that the scores of the Knowledge and En were significantly associated with the number of food taken per day for condition of adjusting socio-demografic factor and A effect. Also, En was important variable in explanation of the balanced diet and A, En were important in the general food habits for adult.

According to KISA, many people play smartphone games. stress relieving, time is the reason to beat. Attempts to combine mobile games and education in the Korean game market are continuing. Studies have shown that using commercial games for education can be effective. Also, researches for activation educational games are increasing. Creating educational games requires a lot of time and money. Due to the nature of mobile games, the service is often terminated without updating. If you are able to acquire a naturally educational part while playing mobile games, you will see the effect of one pair of fun and education, both at once. We analyzed the education factors of the game with 'Real Farm' which is a simulation farm game. We focused on analyzing information acquisition and utilization part through indirect experience which is characteristic of simulation and examined educational factors based on design elements of educational game. This can signal the positive aspects of the game and the educational content of existing games. If you use smartphones as a pedagogy, you can expect a positive perception of games and an increase in the average life expectancy of mobile games.

An environment model that is constructed using a single image has the problem of a blurring effect caused by the fixed resolution, and the stretching effect of the 3D model caused when information that does not exist on the image occurs due to the occlusion. This paper introduces the registration and integration method using multiple images to resolve the above problem. This method can represent parallax effect and expand the environment model to represent wide range of environment. The segmentation-based environment modeling method using multiple images can build a detail model with optimal resolution.

This study was conducted to investigated the effects of stocking density on growth and survival of sea cucumber, Apostichopus japonicus in the indoor multiple tank for 12 weeks. There were six treatments(stocking densities) in this experiment, i.e. 1, 2, 3, 4, 5 and 10 individuals per 10 L plastic aquarium($W41{\times}H24{\times}D11cm$, represented as D1, D2, D3, D4, D5 and D10, respectively). Each treatment had ten replicates. The results showed growth variation of sea cucumber, Apostichopus japonicus decreased with the increase of stocking densities. After the end of the experiment, no significant differences(P>0.05) between D1~D5 treatment group whereas significant differences(P<0.05) between D1 and D10 treatment group. Survival rate showed D1~D10 were 90%, 90%, 100%, 95%, 94% and 72%, respectively. Especially, significant differences(P>0.05) between D1~D5 and D10 treatment group. The results indicated optimum of stocking density for sea cucumber, Apostichopus japonicus within five individuals per 10 L plastic aquarium($0.05individuals/m^2$).

Currently, the lack of equipments for the medical practice and education made it impossible for the people in medical institution to carry out suitable experiments for observing human bodies. In this paper, the authors embodied three dimensional images and moving pictures for the human skeletal structure, digestive organs, cardiovascular system and their processes over the internet framework. The three dimensional images and moving picture made it possible for the general people as well as the specialists to observe and obtain informations with regard to the human body. Especially, the authors realized a framework for visualizing the human bodies in three dimensional images, via which a detailed and realistic architecture for the human body and its organs can be obtained. The system developed in this paper can be used in the practice and education of the people engaged in medical fields.

In physics, metal simulation is an important mechanism to understand and create concepts. If students have difficulty in mental simulation, understanding the concept of physics also gets difficult. By providing guide for spatial manipulation to students, 3D simulation contents can help them understand the concept of physics. In this study, the 3D simulation contents developed to help understanding the concept of light going straight and shadow is applied to 20 college students. The results, Hake gain is 0.93, showing high level of understanding about the class. In addition, through mental simulation, students predict the phenomenon well about the new context. This is shown that students' understanding of concept through 3D simulation contents are carried out well.
