Mobile robots are used for years as a valuable research and educational tool in form of available open-platform designs and Do-It-Yourself kits. Rapid development and costs reduction of Unmanned Air Vehicles (UAV) and ground based mobile robots in recent years allowed researchers to utilize them as an affordable research platform. Despite of recent developments in the area of ground and airborne robotics, only few examples of Unmanned Surface Vehicle (USV) platforms targeted for research purposes can be found. Aim of this paper is to present the development of open-design USV drone with integrated multi-level control hardware architecture. Proposed catamaran - type water surface drone enables direct control over wireless radio link, separate development of algorithms for optimal propulsion control, navigation and communication with the ground-based control station. Whole design is highly modular, where each component can be replaced or modified according to desired task, payload or environmental conditions. Developed USV is planned to be utilized as a part of the system for detection and identification of marine and lake waste. Cameras mounted to the USV would record sea or lake surfaces, and recorded video sequences and images would be processed by state-of-the-art computer vision and machine learning algorithms in order to identify and classify marine and lake waste.

From the mid-1990s, the discussion on alternative schools began in earnest, and with the increasing interests in them, Korean parents' association of alternative education, KPAAE was launched formally in November, 2008. Among the alternative schools in the nation, thirteen urban alternative schools were studied and analyzed. The result indicated that they are being run by individuals and civic organizations with no approval and the facilities and spatial organization of the schools are poor, which is thought to be mainly due to financial reasons as well as the schools' educational goal that puts emphasis on experiences leading to utilize outside local facilities. With this background, the results from the analysis of the facility status and the spatial organization of urban alternative schools led us to understand the followings: First, it showed that per capita average of area of the urban alternative school is approximately 11.995m$^2$, less than 14N, the standard area of institutional schools. Second, depending on the form of facilities, the space of other facilities is shared to make up for insufficient space, and is utilized to a small degree and for multi-purposes. Third, the space reflects the disposition of subject students, and is located in the area with convenient traffic for students' attending the schools conveniently. Fourth, specialized space is run on the basis of educational goals, and the exploring of career and the improving of sociality are pursued through internship programs associated with local facilities. Thus, it is desirable for the minimum per capita area of the urban alternative school to meet 14N, the standard area of the institutional schools in order that the urban alternative school may overcome the spatial limitation and the financial hardship stemming from the practically difficult constructing of new buildings and the small scale operation, and it may make flexible use of the space, and the students may live their lives smoothly. Also, it is thought that for the activating of the urban alternative schools, the plans for utilizing various facilities associated with local facilities should be considered.

This study is intended to analyze current status of costume in the cultural industry and explore feasibility of integrating costume as important cultural contents in the digital era. Among the websites for contents as the cultural archetypes, some have strong foundations while others don't. First, as for various archetypal characters restored based on the Korean history, most of their clothes focus on shapes and colors but lack details. They should be produced in 3D to provide back views or textile patterns to users. To ease understanding of the history of costume, user-friendly services such as launch of a pop-up window when users click on specific contents in question should be available for detailed information. At least there should be a link to other related sites where users can conveniently find more details. Second, some sites have too much data under one subject, increasing complexity and undermining orderliness. As a result, it takes long time to identify the site map. In this case, it is required to rearrange the contents with Quick View by subject and related links for in-depth study. Third, each subject is important to develop the archetypes for a variety of purposes. Creation of design derived from them or their commercialization can be an example but these activities should not restrict imagination of users or degrade the value of the archetypes. Last, it is needed to adopt validation system to detect the needs for a regular update (renewal) and to fix errors. We found many servers whose operation is not stable in general. When these technical issues are addressed for stable operation, users will rely on the sites to utilize them for their purpose of developing the cultural archetypes. In conclusion, advancement of www.culturecontent.com is essential. Based on efficient management and operation of the system, the quality of contents would be increased and multi-faceted advertising campaigns focusing on needs should be launched, to promote application of the contents. This is the recommendation for the future of the cultural archetype industry in Korea.

The purpose of this study is to verify the relationships among innovative behavior, turnover intention, and job security. An additional purpose was to examine partial mediating effects on psychological ownership. The baseline of analyzing those relationships in this study is that the role of psychological ownership will be a mediator between job security and turnover intention as well as innovative behavior in the organization. To accomplish these purposes, a model was built among job security as predictor variable, the psychological ownership as mediating variable and turnover intention, and innovative behavior as criteria variables based on the studies conducted in the various areas. The 248 questionnaires surveyed from the area of DaeGu and Kyungbuk were used in the statistical analyses. The detail statistical techniques are such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, and multi regression analysis. The results of the study show that job security had positively significant effect on turnover intention and innovative behavior. In addition, only the psychological ownership of organization-level thinking have partial mediating effects between job security and innovative behavior also job security and turnover intention. The results may indicate that the psychological ownership of organization-level thinking be a key factor to alleviate the turnover intention of employees and to encourage the innovative behavior during their works for the small-medium size companies showing the unstable job security.
