Open education has been established for 10 years in Korea. In spite of relatively long history of open education, there are only two schools which have well structured open space to support open education. Development of open curriculm and open space is a vital elements for the success of open education. This study aims at introducing the concept and development of open space and analyze the role of media center to improve open education. Especially emphasis is placed on how the open space should be organized for the effective open education. The open space should include 4 areas such as instructional area, production area, storage area and teachers' area. There are, however, no standardized format for the open space and education. Open space should be flexibly restructured to adapt to rapidly changing educational environment.

In spite of importance of safety issues in community sport, little concerns have been paid to the sport safety policy. Governing bodies and individuals involved with the facility management have a responsibility to manage the risks at acceptable levels. For sports injury prevention interventions, the safety policy of sport facilities should be made to provide a structured framework which can be implemented at community sport. Hence, the current study is to identify the safety issues and to generate the policies that assist to conduct the systematic safety management at sports facilities. For this, the current study analyzed two cases from Japan and Germany. The study reviewed multiple pieces of literature including journal publications, political reports, and media coverage. Through review, the study analyzed the organizational structure, legal systems, and political stance of the safety management of sport facilities in Japan and Germany. The results proposed the following issues. First, law needs to be enacted to establish the control tower where has a responsibility to develop the safety manual and system. Second, local organizations need to be established to educate individuals working in sport facilities and inspect the facilities. Further political issues were discussed for safety management in Korea sport facilities.

The impervious surface rate increased by urbanization causes various problems on the environment such as water cycle distortion, heat island effect, and non-point pollutant discharges. The Low Impact Development (LID) techniques are significantly considered as an important tool for stormwater management in urban areas and development projects. The main mechanisms of LID technologies are hydrological and environmental pollution reduction among soils, media, microorganisms, and plants. Especially, the media provides important functions on permeability and retention rate of stormwater runoff in LID facilities. Therefore, this research was performed to assess the pollutant removal efficiency for different types of media such as zeolite, wood chip, bottom ash, and bio-ceramic. All media show high pollutant removal efficiency of more than 60% for particulate materials and heavy metals. Double layered media is more effective in reducing heavy metals by providing diverse sizes of micro-pores and macro-pores compared to the single layered media. The results recommend the use of different sizes of media application is more cost-effective in LID than a single size of media. Furthermore, soluble proportion of total heavy metal in the stormwater is an important component in proper media selection and arrangement.

This study aims to assess the current understanding of the landscape of wind power facilities as renewable energy sources that supply sightseeing, tourism, and other opportunities. Therefore, social media data related to the landscape of wind power facilities experienced by visitors from different regions was analyzed. The analysis results showed that the common characteristics of the landscape of wind power facilities are based on the scale of wind power facilities, the distance between overlook points of wind power facilities, the visual openness of the wind power facilities from the overlook points, and the terrain where the wind power facilities are located. In addition, the preference for wind power facilities is higher in places where the shape of wind power facilities and the surrounding landscape can be clearly seen- flat ground or the sea are considered better landscapes. Negative keywords about the landscape appear on Gade Mountain in Taibai, Meifeng Mountain in Taibai, Taiqi Mountain, and Gyeongju Wind Power Generation Facilities on Gyeongshang Road in Gangwon. The keyword 'negation' occurs when looking at wind power facilities at close range. Because of the high angle of the view, viewers can feel overwhelmed seeing the size of the facility and the ridge simultaneously, feeling psychological pressure. On the contrary, positive landscape adjectives are obtained from wind power facilities on flat ground or the sea. Visitors think that the visual volume of the landscape is fully ensured on flat ground or the sea, and it is a symbolic element that can represent the site. This study analyzes landscape awareness based on the opinions of visitors who have experienced wind power facilities. However, wind power facilities are built in different areas. Therefore, landscape characteristics are different, and there are many variables, such as viewpoints and observers, so the research results are difficult to popularize and have limitations. In recent years, landscape damage due to the construction of wind power facilities has become a hot issue, and the domestic methods of landscape evaluation of wind power facilities are unsatisfactory. Therefore, when evaluating the landscape of wind power facilities, the scale of wind power facilities, the inherent natural characteristics of the area where wind power facilities are set up, and the distance between wind power facilities and overlook points are important elements to consider. In addition, wind power facilities are set in the natural environment, which needs to be protected. Therefore, from the landscape perspective, it is necessary to study the landscape of wind power facilities and the surrounding environment.

The purpose of this study is to quantitatively demonstrate that rational and emotional factors in urban tourist facilities affect visitor satisfaction, positive word of mouth and subsequent revisits. Therefore, the researcher used structural modeling methodology to test the paths and relationships between the rational and emotional perception, satisfaction, word of mouth, and exogenous variables (aesthetics, economic utility, accessibility, emotional attachment, etc.) of urban tourism facilities perceived by users. As a result of the study, users of urban tourism facilities are affected by customer satisfaction such as ease, usability, and pleasure based on intangible assets such as kindness, aesthetics, symbolism, attachment, and rational factors, which are emotional impressions of urban tourism facilities, and utility, and customer satisfaction. These were found to have a positive and lasting effect on users' perceptions of the facility. Therefore, if the rational and emotional values of urban tourism facilities are considered and integrated in marketing, efficiency can be maximized in terms of satisfaction, word of mouth, and future revisits. The researcher considered that this study could contribute to the revitalization of the tourism industry and the city as a whole through the improvement and utilization of various tourism facilities possessed by the city.

과거 CDMA 시스템에서 이동단말과 PSTN 및 PSDN간의 통신이 가능하게 하기 위해서는 망간의 정합기능을 수행하는 연동장치(IWF Inter-Working Function)가 필요로 되는데, 이때 이동단말과 BSC/MSC간의 무선 데이터를 IWF로 HDLC 프레임 형태로 구동하고 반대로 IWF로부터 수신된 데이터 프레임을 이동 단말측으로 전달하기 위하여 HDLC frame driver의 역할이 필요하다. 또한 교환기와 IWF간의 데이터 통신은 Frame-relay 프로토콜을 이용하며 정합기능을 수행해 주어야 한다. 본 논문에서 구현된 기능은 과거 CDMA 의 MSC 내에 구현된 본 기능이 HDLC 정합, Frame-Relay 정합, IPC, Datapath 등의 기능들로 구분되어 분리되어 있는 구조를 통합하여 하나의 기능 Board로 통합하였고 이러한 기능을 MG(Media Gateway) System에 기반하여 구현하여 적용하였다.
