본 논문에서는 프라이버시 보호를 위한 개인 위치 정보 접근에 대한 통보 유무, 동의와 같은 차별화 된 정책 설정과 특정 장소나 시간에 대해 위치 정보 제공을 차단 할 수 있는 프로토콜을 제안 하려고 한다. 제안하는 프로토콜은 모바일 상의 프라이버시 설정을 위해 응용 레벨에서 동적으로 발생하는 개인의 위치정보에 대해 유저가 설정한 특정 장소와 시간에 따라 차단하는 기능 설정할 수 있다. 또한 서비스 제공자와 요청자 별로 개인 위치 정보 접근에 대한 통보 유무, 동의와 같은 차별화된 정책을 설정 할 수 있다. 제안하는 프로토콜은 이들 설정된 정책들의 리스트들을 요청자 별로 나누어서 사용자 프라이버시 리스트 서버(UPLS)에서 관리하며, 서비스 요청 시 설정된 정책에 맞는 서비스를 서비스 제공자들이 제공하게 되므로 개인 위치 정보에 대해 프라이버시를 제공하게 된다.

위치 정보 제공 시스템은 이동성이 있는 물건 또는 개인이 특정한 시간에 존재하거나 존재하였던 장소에 관한 정보를 제공하는 시스템이다. 시각 장애인들은 인도, 교차로, 계단, 엘리베이터 등 위협요소가 있는 특정 장소 등의 환경 문제로 사회의 참여가 어렵다. 이에 거리 곳곳에 설치된 RFID Tag의 위치정보를 다양한 통신망을 활용하여 중앙 서버의 MAP 데이터에 연계 시켜 시각 장애인에게 음성 및 경고 알림 진동으로 길을 안내해주는 위치 정보 제공 시스템을 설계하였다.

Point-of-Interest(POI) recommendation systems suggest the most interesting POIs to users considering the current location and time. With the rapid development of smartphones, internet-of-things, and location-based social networks, it has become feasible to accumulate huge amounts of user POI visits. Therefore, instant recommendation of interesting POIs at a given time is being widely recognized as important. To increase the performance of POI recommendation systems, several studies extracting users' POI sequential preference from POI check-in data, which is intended for implicit feedback, have been suggested. However, when constructing a model utilizing sequential preference, the model encounters possibility of data distortion because of a low number of observed check-ins which is attributed to intensified data sparsity. This paper suggests refinement of temporal intervals based on data confidence. When building a POI recommendation system using temporal intervals to model the POI sequential preference of users, our methodology reduces potential data distortion in the dataset and thus increases the performance of the recommendation system. We verify our model's effectiveness through the evaluation with the Foursquare and Gowalla dataset.

The most prominent phenomenon in performing arts in recent is the social sharing of art products. As a result of the city's reinterpretation of each local government, production of performances, activation of performances outside the theater, and performances performed in streets and specific spaces and public spaces deviate from traditional theater-based performance forms through social communication and expansion. Also, it is seen as an effort to expand the delinquency of the act. Furthermore, it can be said that this proves the publicity of contemporary performing arts. I will research the audience and learners through the Opera Estate festival, a recent exhibition in the Balsano del Grappa, Italy, which is based on the site-specific performance form that has been actively conducted several years ago.

Site-specific performance is always the real on-site work taking place at the site. Hence, it deals with the reality, in other words, the time of creation and formation. And it creates value and meaning through the interaction and continuous direct communication process between the performers, audience and the local residents. In this performance, the audience's status as the passive observer changes. They become the co-agent who actively lead and complete the performance through their own experience. We have examined the The Working Methods of Site-specific Performance and Aesthetics of Effect through four Korean performances ; Marie, An aesthetic experiment of site as the storyteller; Heterotopia and Urban Movement Research or Play: We Will Move Your Sofa, as performances which have Revealed history, politics, institution engraved in the site ; A Song of Mandala and Miracle, as a ritualistic site-specific performance at the historic site. Some remarks on Site-specific performance ; First, In Site-specific performance, the habitus peculiar to the stage art and the mode of reception are changed. Second, a new mode of theatrical communication requires creator and audience to have a sharp aesthetic sensibility and to change one's perceptual habit. Third, Site-specific performance can act as a demonstration for the viewpoints of political activism through what could be called a dramatic close-up effect. Fourth, Site-specific performance also has the risk of merely becoming an unfocused and scattered performance or degenerating into a pseudo-sightseeing. To avoid this, an in-depth study of the site and its socio-cultural context, and the clear motivation with which one is trying to reveal and tell from the site must be indispensable. As the co-agent, the audience should also be aware and think about what the given performance signifies today.

Humans have been searching for more comfortable places for centuries. The comfort concept which is related with vitality in Pungsu is closest to science. The comfort concept was introduced as being based upon measurable human physiological and psychological reactions. Two classification nomograms, the comfort index and the wind effect index were identified. The Pungsu concept can be applied in America, and one of them is North Cemetery located in the town of Hampton in northeastern Connecticut not far from Storrs campus, the University of Connecticut. The human reaction to comfort not only physiologically but also individually is various in various climate region. It is important to search for more comfortable places or to make up for less comfortable places with Pungsu as the adaptive strategy for the comfort.

The research study was conducted for development of the advanced image analysis service system based on deep learning. CNN(Convolutional Neural Network) is built in this system to extract learning data collected from Google and Instagram. The service gets a place image of Jeju as an input and provides relevant location information of it based on its own learning data. Accuracy improvement plans are applied throughout this study. In conclusion, the implemented system shows about 79.2 of prediction accuracy. When the system has plenty of learning data, it is expected to predict various places more accurately.

특정 소수에서 사용되던 인터넷이 불특정 다수의 사람들에게 장소에 구애받지 않고 점차 확산 되어 오면서 사용자의 요구 및 그 시장 역시 기하급수적으로 증가해왔다. 처음에는 단순히 접속 속도 향상에서부터 현재는 무선이라는 접속방법의 발전까지 사용자의 편의를 위한 기술 개발 노력은 결실을 맺고 있다고 해도 과언이 아니다. 최근에는 댁내까지 서비스되는 PC 중심의 인터넷 기술뿐만 아니라 다른 가전기기를 통한 통신 및 가전기기의 제어 및 모니터링 등 좀더 사용자 편리성을 강조한 삶을 영위하고자 하는 욕구가 점차 증가하고 있다.(중략)

In East Asia, regional identity can be expected to obtain popular consent more successfully when it is firmly based on historical-geographical reality. This study is an attempt to apply a broadened concept of place to the identification of East Asia as a cultural region. Cultural mixture within places at various scales, rather than cultural integration across those places, would give greater coherence to East Asia as a cultural region. This cultural mixture varies from one place to another, depending on the relative position in power relations. It could appear in the form of either domination or resistance, and even entanglement. The concept of a "mountain as a contested place" is proposed as an experimental effort to search for the basis for cultural identity within East Asia. This concept of place should be extended to the individual studies of such spatial units as houses, gardens, villages and cities. These individual studies, if accumulated, would result in improved theories of East Asia as a region that has a distinct cultural identity in historical-geographical terms.
