Analysis systems and databases covering economics and industrial areas in Japan have long history, but due to considerable depth in specialty those have been used only by limited, certain patrons. It means that there are still few of practical system services at full scale. This paper describes the representative system services. Taking an example of interest prediction the author explains now to utilize systems and some points to be reminded. He also describes how to confirm newspaper information, how to predict economics, how to use various kinds of models based on economic prediction, and industrial analysis. Researches and studies are very often proceeded on economic prediction, and industrial analysis. Researches and studies are very often proceeded through interaction among researchers. So that we should make efforts continuously such as to rountinely get familiar with systems, to exchange information among users, to utilize helpdesks every time we need.

Objectives : The purpose of the study is to investigate the education, certification system, and extent of duty of dental hygienist between Korea and five developed countries including United States, Canada, England, Australia, and Japan. Methods : Internet based access to five developed countries was made and the analysis was done for the definition of occupation, main duties, similar occupations, education policy, job descriptions, license certification system, standards of duty, Q & A management, current status of obtaining certification, and scope of work. Results : United States has a two-year associate degree(AS) and a four-year bachelor degree(BS). Canada has two to three years degree and a two-year course is accepted in england and Australia. In the meanwhile, Korea and Japan have two-year and four-year educational courses. The duty of dental hygienists includes the prevention education for dental health and continuing dental health care. Most of the dental hygienists in Korea and Japan play the assistant roles for the dental surgeons. United States has national board examinations including written examinations, practical examinations, and computer assisted examination. Written and practical examinations are also conducted in Korea. England and Australia have the recognized educational organizations for qualification. Conclusions : Problem based and problem solving skills are the most important in dental hygienist education in Korea. The training of highly competent dental hygienists must be done for the improvement of dental hygiene in Korea in the near future.

This paper aims to develop the photography education method based, not on the practical technique, the photo recording or the communication, but on the photo theory and the visual culture. This paper can be summarized as follows: First, it analyses the photo theory itself and photography education theory. It examines the studies of the important scholars of photography theory, namely Laszlo Moholy-Nagy, Walter Benjamin, Susan Sontag. It examines also the studies of the scholars who applied photography to education, that is, Victor Burgin, Simon Watney, David Bate. This paper examines how photography is related to education theory in general and where photo education can be situated in art education field.

Some of radioactive contamination is unavoidable in the facilities using the unsealed radioactive material. The primary purpose of radioactive contamination control in the workplace with contamination concern is the effects from the potential intake of radioactive material into the body. This paper provides procedures to estimate the level of internal exposure for the worker based on the conservative assumptions and simple calculations. They consist of two processes; to calculate air concentration of radioactive material and annual intake by inhalation with contaminated air and to compare each of them to Derived Air Concentration and Annual Limit on Intake mentioned in the related notification. The procedures are applicable to make a decision on practical requirements for monitoring air contamination and internal exposure of worker as follows; needs for measurement of air contamination and internal exposure and acquisition of information on the design of the ventilation system.

The new paradigm of 3D printing is that no one is clearly easy to regulate or estimate the impact adverse on existing industry or the form of new business models. Nevertheless, it will be judged that there is no person to deny about potential possibility of implicated 3D printing technology by industrial and business aspects. This study has the purpose and significance of that to suggest practical education which is available as practical application because new creative tools in design department are expected to have greater impact and use of 3D printing technology. Based on the analysis of research on the work process of 3D printing technology for this purpose, we composed the step-by-step curriculum linkages which combined theory and practice for student to create the well-made final output.

Recently, the utilization of the BIM system has been extended to cost and resource simulation, visualized management of construction site information and application of augmented reality including basic 3D modeling. Therefore, various BIM functions are being developed for practical applications. However, since clear classification criteria and knowledge information of BIM functions are not sufficient for field engineers, it is difficult to identify the necessary BIM functions for a construction project. This study suggests a BIM function breakdown structure considering the individual functional properties and a process model that can be ordered by applying BIM in a railway construction project. The proposed delivery model is used to obtain a practical utilization of BIM by analyzing features applicable to railway construction projects; model is verified using a case project.

Scanimation is utilized in various fields due to its simple and easy basic principle, whereas mostly it is expressed in gray scale, and the cases of expressing with color is rare. This research classified scanimation into form change of the images with no connectivity, continuous motion of the images with connectivity, and optical illusion with continuity along with visualization effect based on the advanced research and utilization case, and conducted a comparative analysis of scanimation per type applied with color scheme by color difference based on PCCS(Practical Color Co-ordinate System) system. Based on this research, the researcher intended to suggest various direction and expressive method of scanimation using color, expecting the research result could be a valuable reference for the researches utilizing scanimation, henceforth.

South Korea's percentage of the self-employed still ranks among the highest amid OECD nations and thus is perceived to be a huge burden on the national economy. Accordingly, the government is continuing its support with the expectation that a support policy is needed for the self-employed. However, few analytic studies exist so far on the economic effect of the government's support of the self-employed. Thus, this study analyzes the practical effect of the government's self-employed support. According to the estimation result while determining the sales amount of the self-employed, the labor input, business period, age, gender, prior business preparation period, and the experience variable of the self-employed support policy are shown to be significant. The result of this study provides an important practical guideline on the political factors that should be prioritized when the government politically supports the self-employed.
