New technologie of information and interaction create ambiguous, multifaceted relationships between concepts and realities that once seemed clear and simple. The acvent of cyberspace implies the existence of cyberplaces and relationships among cyberspace and places that could be as or more complex then those that exist among the spaces and places of the non-digital world. Virtual reality-the current uses of infomation technologies to create replicas of places and processes in the world-offers a point of exploring such relationships. But more penetrating insights become evident in the examination of real virtuality-the uses of information technologies to enhance the experience of places in the world. Real virtuality offers geographers a variety of innovative and powerful tools for augmenting the effectiveness and domain of their craft. Widespread use of real virtuality by geograpgers will alter their use of data, methods, and theory in research, teaching, and practice.

As high schools implement credit completion system these days, concerns about the dissolution of classes, which are the original stable groups of studying and living, and the instability of the basal space, is growing due to the extended operation of moving optional classes. The purpose of this research is to understand the effect that environmental features of the basal space within the school and the operation method have on the students' space use and formation of attachment place within the school. For this, the main activity places, attachment places, school life satisfaction and others were investigated at 2 Japanese credit-based comprehensive high schools, which are different in the physical environmental features of school buildings. Based on this, a quantitative analysis about the distribution of activity places and attachment places was implemented. The space use features for each student attribute were compared, and the school life satisfaction for each type of attachment place formation was analyzed. As a result, the change of the territorial consciousness about the class space according to the implementation of moving optional classes could be understood. And it was confirmed that the students' space using behavior and place evaluation change according to the physical environmental feature of the class space and common space, and that this is affecting the life satisfaction of students.

Objectives: We examined the prevalence of tobacco use and exposure to secondhand smoke among middle-school students in Korea using the Global Youth Tobacco Survey (GYTS) in 2013. Methods: The GYTS in Korea was conducted between July and August 2013 by the Korea Centers for Disease Control and Prevention. Data were collected using a self-administered anonymous questionnaire from a nationally representative sample of middle-school students aged 13-15 years in sampled classrooms. Results: The GYTS in Korea was completed by 4235 students aged 13-15 years in 43 middle schools. Approximately one in five of the students (17.8%) reported that they had tried cigarettes in the past, while 5.2% reported currently being cigarette smokers. Current cigarette smoking was higher in boys (7.5%) than in girls (2.6%). Of the students, 29.7% had been exposed to secondhand smoke at home, 47.4% inside enclosed public places, and 53.9% in outdoor public places. Of the current cigarette smokers, 25.7% bought their cigarettes from a store despite a law prohibiting this. Additionally, 58.0% of students noticed point-of-sale tobacco advertisements or promotions, 66.8% of current cigarette smokers wanted to stop smoking, and 70.9% of students had been taught about the dangers of tobacco use in school. Conclusions: These findings provide an opportunity to develop, implement, and evaluate a comprehensive tobacco control policy. The results suggest that youth have relatively easy access to cigarettes and are regularly exposed to secondhand smoke in public places, as well as to point-of-sale tobacco advertisements and promotions. Strict enforcement of the ban on tobacco sales to youth, expanding smoke-free areas, and advertising bans are needed to reduce tobacco use among youth.

In order to provide basic data for designing the outdoor exercise environment to promote the health of the citizens, this study has analyzed the status of citizens' use of outdoor exercise places that have been supplied extensively recently and the factors affecting the citizens' choice of the places. A survey was made on 20 spots in 12 places where outdoor exercise equipment is installed to identify the characteristics of use and the factors affecting the selection of the spots and for the 1,733 survey sheets collected finally SPSS program was used to analyze the multiple answers. Major results of this research are as follows: First, since light exercise equipment mostly for bodily exercises has been installed, it has brought practical effects for the physically weak people, aged people and the people who scarcely exercise, while decreasing the users' economic burdens. Second, the scales of important factors the users think in selecting their exercise spots were 'spaciousness (2,028 times)' > 'accessibility (1,751 times)' > 'fitness (1,583' > 'supportability (1,445)' > 'community centeredness (1,260).' Third, the ratios of important factors regarding the choice of environment of outdoor exercise were 'near to walk (16.1%)' > 'nice natural environment (12.3%)' > 'always free to exercise (9.7%)' > 'shortage of exercise equipment (7.4%)' > 'possible to accompany family/neighbors (6.7%)' > 'no economic burden (6.5%).

Movable scaffolding has been used to work in high places. The scaffolding is economical and convenient to move to other places, but it has the risk of falling down. This paper proposes a fixed bracing system to prevent the falling down of a movable scaffolding, and evaluates its usability by making a small-sized model. Further studies of structural stability, safety, and economical efficiency is necessary to use the system practically.

This paper investigated the human distribution in subway station areas in Seoul, using geotweets and subway ridership data. Eight stations were selected from the districts of Gangnam and Gangbuk. Geotweets located within a 600-meter radius of the central coordinates of each station were extracted, and distances between the center of station and each tweet location were calculated. Donut-shaped dimension and pie-shaped dimension were generated, using the Haversine distance formula and the Azimuth angle formula respectively. By combining the two dimensions, Dartboard-shaped space division is created. Popular places within the subway station areas identified from this research are almost the same as the current well-known popular places, and this is an important case showing that people send tweets from various places where they engage in daily activities. We expect this study can be a methodological guideline for social scientists who use spatio-temporal or GPS data for their research.

The purpose of this study is to develop a program that enables students to participate in various experiential learning places in order to provide various experiences to students for solve the problem of prejudice to specific places such as science museum, zoo and botanical garden. For this purpose, the surveys were conducted about experiential places and awareness of experiential learning. 88 elementary school teachers participated in the survey. As a result, they were positive about the use of experiential learning in elementary science instruction, but there were responses that a lot of preparations for the progress and efforts were needed. Therefore, if instructional materials and teaching materials for experiential learning are given, it is confirmed that the intention of using is increased. And the results were analyzed and the experiential sites were categorized into 12 types. We could present basic data that can diversify not only the science museum but also science related experiential places. We developed a learning program related to 'The Liquid and Gas' unit of the third grade, And 'Life unit of Plant' unit of the third $4^{th}$ grade. Through this study, we intend to help science experiential learning to be activated and student - centered experiential learning to be realized.

This study deals with six spa touristy places to analyze the similarity in image and selection factor recognition through multidimensional scaling method. The result is as following. First, as a result of analysis in the similarity in Image of the 6 touristy Spa places, each "Asan and Onyang" and "Suanbo and Ducksan" form different similar image groups. However, Yoosung does not share the similarity in Image that other Spa places own. Second, as a result of analysis of selection factors in the six touristy spa places, it is found out that there is no big difference in selection factors such as 'spa facility', 'a fee to use', and 'quality of service' in the six spa places. Yet, Onyang, Yoosung, Ducksan, and Suanbo spa reflect high selection factor as 'a recognized spa place' different from Asan and Dogo where the reflection of selection factor is low. Onyang, Yoosung, and Dogo regions reflect high selection factor as a 'Touristy destination' while Asan reflects low selection factor.
