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 study aims to present the criteria of location selection and contents composition of Sewol ferry memorial space from the perspective of placeness and dark tourism, one of the main concepts of cultural tourism theory, and to draw academic concepts and implications related to it. First, the location selection of Sewol ferry memorial space was proposed by applying the concept of placeness to each important location, and the direction of the contents composition was presented based on the contents components such as characters, stories, places and dark tourism composition directions. As a result, when the Sewol ferry memorial space is designed in use of systemizing the narrative structure of the storytelling method and implementing it specifically, it is suggested that it is possible to construct a Sewol ferry memorial space by distributing and course-making based on the narrative structure rather than focusing on the location selection of a specific place. In addition, it was argued that the contents composition criteria should be more complex and systematically established and applied considering the connection between placeness and dark tourism when the Sewol ferry memorial space is constructed in various sites like 416 life safety parks and Mokpo New Port. This study, which aims to answer research questions related to major issues based on the perspective of placeness and dark tourism on the Sewol ferry memorial space, is expected to be used as a reference for the construction of the memorial space in the future.

Citizens of 21st century which is called to be the era of 'Culture' express their cultural desires in their public environments. Governments found that these needs can be satisfied through the culture-centered public designs which are based on the local resources and identities. This research suggests the strategy programming model to support these projects. It aims at not suggesting the conceptual process model, but developing the practical supporting model with options to choose. Thus the indices which are related to each prototype phases of programming process are analyzed through the case analyses with qualitative approach. This paper focused on analyzing the indices for Place Strategy which includes the phases for Resource, Mission, and Targeting. Altogether, 81 indices are analyzed.

The shielding coefficient of a conductive length structure is calculated by a ratio of induced voltage with that structure to without that structure. The environments are different between with a structure and without a structure. Beside the corresponding structure, all the parameters related to induced voltage should be normalized to a presumable same environment conditions. Basically each parameter must be compensated, which is a bottom-up type method. In this case, some parameter is not possible to be so because of its unknowing function. Then as a calculated voltage already has all characteristics of parameters, seeking a ratio of calculated induction voltages themselves will include the compensation of all parameters automatically. This is a top-down method.

The purpose of this study is to grasp the spatial characteristics and consciousness structure for The Third Place through the empirical research, focused on housewives as the survey who spend many times in neighborhood. The four types as the consciousness structure are deducted, Nature-oriented type, Unusual experience type, Solitude enjoyment type, and Originality-oriented type. And the spatial characteristics related to the four types are deducted as the followings: Nature-oriented type contains the spatial characteristics as Wild space, Speculative space, Dotty occupation space, and Green way. Unusual experience type contains as Rambling space, Dynamic sojourn space, and Theme-plex space. Solitude enjoyment type contains as Anonymous private space, Encircling space, and Religious space. Originality-oriented type contains as Chatter space, Self development space, and Community space between families. The results of this study represent six characteristics on the third place, advocated by Oldenburg, and show housewives' various needs and concrete examples for the Third place in city.

몇 년 전부터 유행하고 있는 성격 유형 검사는 여전히 MZ세대들 사이에서 인기를 끌고 있다. 본래는 학교나 군대에서 성격 유형과 적성 파악을 위해 활용하던 검사였지만, 과학적 근거가 있으면서도 자신의 성격 유형을 쉽게 확인할 수 있어 하나의 문화로 자리 잡았다. 이에 마케팅 시장에서는 유형 검사를 활용하여 브랜드·제품 홍보에도 쓰이고 있다. 본 논문에서는 연애와 관련된 유형 검사 사이트를 구현하고 참여한 사용자들이 입력한 정보와 선택한 설문, 결과를 바탕으로 전체 사용자, 남녀로 구분 지어 유형별 선호하는 데이트 스타일을 분석하고자 한다. 유형별에 맞는 데이트 장소를 추천하는 시스템을 개발하고, 이러한 시스템을 통해 데이트 장소를 정할 때 사용자들의 편의성을 도모하고 분석한 내용이 마케팅 시장의 브랜드·제품 홍보와 이벤트에 유용하게 사용될 것으로 기대된다.

The purpose of this study focused on the distribution of crimes in Cheongju City. This study emphasized the characteristics of place and spatial pattern of crime in Central Business District(CBD). The crime core areas were delineated and explained through land-use based on fieldwork and GIS analysis For this aim. the police crime data of Cheongju Dongbu(east). Seobu(west) for 1998 were collected In which 3.909 indictable or similar offenses were reported. In this study, Included climes are murder. rape, robbery. arson, theft, burglary, assault and vandalism. Because theme crimes are related with site-specific crime. As a result. land-use patterns are often related to specific type of offenses. The climes in Cheongju City were concentrated in the CBD Most crimes were assaults and thefts Crime areas can be classified by the age of the offender Around Chungang and Pungmul Market in the CBD. the offender＇s ages were 30-50 dominantly Assaults and thefts were concentrated in Songan-gil(street). which is a place teen-ages and youngsters meet frequently The result of the buffering analysis with roads, explained 40% of crime within a 30m buffer area( including both sides) of a principal road The rest of the climes mainly occurred in the vicinity of narrow streets and alleys.

Traffic regulations are expanding to prevent traffic accidents for people's safety, but traffic accidents are not decreasing. In this study, the probability of traffic accidents occurring at a specific time and place is estimated by analyzing various factors such as weather forecast data from the Meteorological Agency, day of the week, time of day, location data, and location information. This study combines objective data on the occurrence of numerous previous traffic accidents with various additional elements not considered in previous studies to derive a more improved traffic accident probability prediction model. The results of this study can be effectively used for various transportation-related services for the safety of people.
