Along with technological development and change of perception, the form of advanced game space appears in various ways. And some game spaces have gradually gotten factors of placeness and become a place. The main purpose of this research is to identify the characteristics of game space from a place-based perspective. For this, the generations are divided into four sections based upon the factors of placeness. At the first generation, there are no elements of placeness. But as time goes by, elements of placeness have been increased gradually. Finally, in the fourth generation, various elements of placeness are found in some game spaces. This study offer insight into game space in a diachronic viewpoint and humanistic approach.

Visual place recognition (VPR) is a fundamental yet challenging task of mobile robot navigation and localization. The existing VPR methods are usually based on some pairwise similarity of image descriptors, so they are sensitive to visual appearance change and also computationally expensive. This paper proposes a simple yet effective four-step method that achieves adaptive convolutional neural network (CNN) landmark matching for VPR. First, based on the features extracted from existing CNN models, the regions with higher significance scores are selected as landmarks. Then, according to the coordinate positions of potential landmarks, landmark matching is improved by removing mismatched landmark pairs. Finally, considering the significance scores obtained in the first step, robust image retrieval is performed based on adaptive landmark matching, and it gives more weight to the landmark matching pairs with higher significance scores. To verify the efficiency and robustness of the proposed method, evaluations are conducted on standard benchmark datasets. The experimental results indicate that the proposed method reduces the feature representation space of place images by more than 75% with negligible loss in recognition precision. Also, it achieves a fast matching speed in similarity calculation, satisfying the real-time requirement.

Korean peninsula has a long history and a geopolitical location as a buffer tone, which has provided the conditions for cultural dynamism and diversity across space and time. The changing processes of place names in Korea is considered to be better suited to the study on cultural politics that is interested in the culture wars over the meaning of culture among different social subjects. In order to ensure the legitimacy of cultural politics for the study of place names in Korea, this study attempts to make a theoretical construction based on the concepts of place identity, territorial contestation, and the politics of scale. Cultural and linguistic theories to be best applied to the study of place names in Korea are the theories on Angehm's and Castells' identity, $P{\hat{e}}cheux's$ identification, Hall's decoding, and Voloshinov's ideological sign. Power relations involved in the inclusion and exclusion are necessarily concerned with the process of constructing a place identity or territorial identity by means of a place name, which represents identity and ideology of a social subject. In the examination of this process, it is necessary to take the elements of identity, ideology and power relations into consideration. In this study, therefore, the politics of scale is experimented for its applicability in the study of place name in Korea, which is expected to accommodate concepts of boundary, territory, territoriality and territorialization. In the end, it is suggested in this study that a series of basic and interdisciplinary studies on the cultural politics of place names in a range of area should be undertaken along with the enough theoretical knowledge of cultural politics.

This study examined the implications of a place-based earth science program integrated with Mathematics. 11 pre-service earth science teachers and 22 middle school students participated in the service education activities of earth science for 30 hours focusing on the measurement of the earth's size through earth science experiments as part of the middle school curriculum. In order to minimize errors that may occur during the earth's size measurement experiments using Eratosthenes's shadows length method of the ancient Greek era, the actual data were collected after triangulation ratios were conducted in the locations of two middle schools: one in remote metropolitan and the other in rural area. The two schools' students shared the final estimate result. Through this process, they learned the mathematical method to express the actual data effectively. Participants, experienced the importance and difficulty of the repetitive and accurate data acquisition process, and also discussed the causes of errors included in the final results. It implies that a Place-Based Earth Science Program activity can contribute to students' increased-understanding of the characteristics of earth science inquiry and to developing their problem solving skills, thinking ability, and communication skills as well, which are commonly emphasized in science and mathematics in the 2015 reunion curriculum. It is expected that a place-based science program can provide a foundation for developing an integrated curriculum of mathematics and science.

Place awareness is an essential for location-based services that are widely provided to smartphone users. However, traditional GPS-based methods are only valid outdoors where the GPS signal is strong and also require symbolic place information of the physical location. In this paper, environmental sounds and images are used to recognize important aspects of each place. The proposed method extracts feature vectors from visual, auditory and location data recorded by a smartphone with built-in camera, microphone and GPS sensors modules. The heterogeneous feature vectors were then learned by an ensemble learning method that learns each group of feature vectors for each classifier respectively and votes to produce the highest weighted result. The proposed method is evaluated for place recognition using a data group of 3000 samples in six places and the experimental results show a remarkably improved recognition accuracy when using all kinds of sensory data comparing to results using data from a single sensor or audio-visual integrated data only.

In this paper, we present a MapReduce-based mobility pattern mining system which can predict efficiently the next place of mobile users. It learns the mobility pattern model of each user, represented by Hidden Markov Models(HMM), from a large-scale trajectory dataset, and then predicts the next place for the user to visit by applying the learned models to the current trajectory. Our system consists of two parts: the back-end part, in which the mobility pattern models are learned for individual users, and the front-end part, where the next place for a certain user to visit is predicted based on the mobility pattern models. While the back-end part comprises of three distinct MapReduce modules for POI extraction, trajectory transformation, and mobility pattern model learning, the front-end part has two different modules for candidate route generation and next place prediction. Map and reduce functions of each module in our system were designed to utilize the underlying Hadoop infrastructure enough to maximize the parallel processing. We performed experiments to evaluate the performance of the proposed system by using a large-scale open benchmark dataset, GeoLife, and then could make sure of high performance of our system as results of the experiments.

This research, which sought to conjecture the formation process of tribal landscape while confirming the method and characteristic of place attachment of the Haeju Oh Family, which is rooted within the village and the Yongwon Pavilion and Garden of Gohak-ri, Mari-myeon, Geochang-gun, Gyeongnam, reached the following conclusion based on the interpretation and analysis of cultural and scenic elements such as the names and sculptures nearby the village and Yongwon Pavilion and Garden. This place is where Goohwagong Oh Sue, a Haeju person, settled down. This is also where his descendants were refined while yearning for their ancestors. The Yongwon Pavilion was established in 1964. It can be sufficiently known that this place was managed and maintained as a garden-like place where the spirit of yearning was shared and which was the basis of the life and entertainment of descendants after being the monumental place for Master Oh Guhwa, through stories, documents, nearby facilities, and writings on many rocks. It is clear that the meaning of 'Bang-Hak(訪鶴) and Jung-Hak (停鶴)' which is carved in many places around this area and Gohak-ri, which symbolizes the Hakbong(crane peak), the vein of Wonjak-dong which is one of the Ahneuisamdong(three outstanding scenic places of Ahneui), is a scenic language explaining the ecological settlement and lives of the Haeju Oh Family. When considering the definition of a sense of place as "a 'social device' made by discussions and practice rather than its existing as a substance," the many structures scattered around the village, Yongwon Pavilion Garden, and nearby designations show the monumental place inheritance of tribal group clearly exhibiting the characteristics of a Korean sense of place. Ever since Guhwagon Oh Sue settled down in Guhak-ri, the tribal group of Haeju Oh Family went through a life settlement phase and landscape formation phase by realizing the sense of place. Afterwards, while yearning for ancestors and repeatedly rooting down in the place, territoriality expanded and the place was reproduced. In particular, timber houses and monuments were constructed during the Japanese Colonization Period, and after independence, the Yongwon Pavilion was constructed through place reproduction, and monumental tribal landscape is currently being expressed in various forms to this day. Thus, allowing to reach the conclusion of 'Tribal Landscape of Gohak-ri, Mari-myeong, Geochang-gun,' which we perceive today. The products of territorial expansion formed by the repeating phenomenon of place rootedness and place attachment by tribal groups are in fact the substance of tribal landscape. Through such, it is possible to confirm the true spirit of place attachment and the earnest interest and affection of descendants towards a unique place that is repeatedly constructed and inherited within the group memory.

This research aims to discuss the impact of on regional development as a place brand and glocal heritage. Based on understanding of the changes and influences of local heritages in the globalization era as a key component of place branding, this study explores how is used to develop a place branding strategy for Lijiang. The research methods are both a literature review and a field research related to Lijiang and its culture. Also, the resources from news, internet, and YouTube are used to analyze the impact of . The performance has been attracting tourists from both Chineses and foreigners and contributed to increase the economic profits of local tourism industry as one of the representative identities of Lijiang. Also, in the process of preservation and recreation of cultural heritages of Lijiang such as , the participation of local residents and on-going interactions between the residents and global tourists highly influence on a transition from place marketing to place branding. By applying local cultural heritages to place branding strategies, the regional values of Lijiang strengthen its place identity from a place of preserving a minority's heritage to that of flourishing cultural exchanges and hybridization from the world.

In the era of glocalization, the role of the state is gradually being reduced and the roles of cities and regions are becoming more critical, especially for the everyday life of residents. Many attempts have been made to secure regional competitiveness based on local identity, to differentiate it from other cities and regions, and to search for methods of sustainable development. The importance of place, which affects human life-world, is getting to garner more attention whereas the large-scale development-centered approach has becoming less prominent. The objective of the study is to investigate the concept of place-making and to apply for the East Asian regions, which seems to be differentiated from urban cultural frameworks of the West. The paper employs comparative methodology for the placemaking strategies of the three case locations, say Mok-dong in Seoul, Koganecho in Yokohama and red town in Shanghai. By through examining the three stages of place-making for each three place, it reveals that cultural identity is quintessential in the East-Asian region. In conclusion, it suggests a sustainable place-making strategies for urban areas in East-Asian regional setting.

In this paper we present a vision based place recognition method which uses Bayesian method with feed back of image retrieval. Both Bayesian method and image retrieval method are based on interest features that are invariant to many image transformations. The interest features are detected using Harris-Laplacian detector and then descriptors are generated from the image patches centered at the features' position in the same manner of SIFT. The Bayesian method contains two stages: learning and recognition. The image retrieval result is fed back to the Bayesian recognition to achieve robust and confidence. The experimental results show the effectiveness of our method.
