The development of the economy and network environment has a great impact on physical stores, and physical bookstores are gradually upgrading and transforming with the pace of the times. This study takes the modern bookstore under the concept of the third space as the research object. The purpose of it is to understand the needs of consumers for the space of the modern bookstores, explore the characteristics and development direction of them, which provides theoretical guidance for the follow-up development of the modern bookstore. Based on the concept of the third space and the theory of lifestyle shops and reorganizing theoretical investigation and prior research, the researcher extracts the characteristic elements of modern bookstores in line with the concept of the third space. Moreover, the research analyzes five bookstores opened in large-scale commercial facilities after 2010 as research cases. Through the analysis of the results, it shows that the modern bookstore is a multi-functional and compounded space which is gradually transformed from a single bookseller to a seller of selling lifestyle proposal. And through the analysis of big data to predict the changes in market consumption, we can find out the different needs of consumers, so as to carry out the targeted design of bookstore space and then improve the value of it. In the context of the co-development of economy and culture, the transformation of modern bookstores actually conforms to the change of consumer demand and realizes a virtuous circle.

프로그램 구현 방법에 편중되어온 기존의 AOSD 방법론이 최근에는 전체 개발 라이프사이클에서 초기 요구사항의 중요성이 강조되면서 요구사항 모델링, 분석, 설계분야에서 많은 연구가 진행되고 있다. 하지만, 요구사항 분석에서 추출된 관심사를 설계하여 구현 단계로 변환하는 과정에서 아직까지 상세화된 프로세스가 부족하다. 본 논문에서는 횡단 관심사 구현 명세 기법을 제시한다. 이 기법은 추출된 관심사를 구현 코드로 변환하기 위한 4단계의 프로세스로 구성되어 있다. 상세화된 명세 기법과 가이드라인은 AOSD에서 해결하기 어려운 설계에서 구현간의 갭을 줄여줌으로써 이해 및 유지보수성을 높여준다.

국가 긴급사태 발생시에는 긴급재난정보를 신속하게 전달하기 위하여 임시재해방송국을 개설할 수 있다. 그러나 국가긴급사태발생 시에는, 시정촌의 기초단체장들에게는 전기나 전화, 휴대폰 등의 연락회선이 두절되어 정보전달 수단이 한정되게 된다. 특히 라디오나 텔레비전 시청도 곤란한 상황에서 재난정보전달체계는 어려운 환경에 처하게 된다. 따라서 재난발생 초기에 임시재난방송국의 역할은 매우 중요하고, 피재지나 피난소에서 얻은 피난정보나 라이프라인정보, 지원물자 배포정보 등의 정보를 제공하고 있다. 본고에서는 동일본 대진재 시의 임시재난방송의 개설 및 운영 등에 관한 임시재난방송국의 운영사례 등을 소개하고자 한다.

오프라인 소비자의 의사결정은 크게 라이프스타일, 동기, 개성, 학습 등 개인적인 영향요인과 문화, 기후, 가족 등 기타 상황적 요인을 포함하는 환경적 영향요인에 의해 결정된다. 이러한 요인들을 입력 값으로 하는 다양한 딥러닝 모델을 이용한 소비예측 연구들이 진행되고 있다. 딥러닝을 이용한 예측모델을 사용하기 위해서는 먼저 요인들이 의사를 결정하는데 있어 얼마나 상관관계가 있는지 파악하는 작업이 중요하다. 본 논문에서는 이를 위해 다양한 상관관계 분석모델을 이용해 소비 의사결정 요소 중 기후, 문화와 같은 상황적 요인과 소비와의 상관관계를 도출하고, 기후, 문화를 대변하는 미세먼지 데이터와, SNS 버즈량 데이터와 소비데이터를 학습하는 소비예측 LSTM모델을 제안하고자 한다.

The purpose of this research was to find differences of children's behavioral pattern between players and non players of the online game "Lineage" in on-line and off line space. As a result, social behaviors of children who play online games were less active than who don't. Based on their motive and behavior pattern in online world, four behavior patterns in online world were identified; "Single-Oriented", "Community-Oriented", "Off-Real World" and "Discriminative." Off-Real World and Discriminative players were more sociable than Single-Oriented and Community-Oriented players. And Discriminative player has more self assertive attitude than others. This study may serve as a model to understand how players will respond to the various game features and how they adopt the virtual world for their interpersonal relationships.

As the water distribution system which is one of the critical lifeline system is deteriorated and pipe failures occur frequently, the more efficient pipe monitoring system becomes a critical issue in the water industry. One of the pipe monitoring systems is called "Smart-pipe System" which is permanent, comprehensive and an automated SIM (Structural Integrity Monitoring) system and has superiorities to existing monitoring system. To implement a smart-pipe system on a water distribution system, assessment of its indirect benefit obtaining from smartpipe such as the ratio of preventing water main failures must be preceded. However, only some researches on this field have been performed. In this paper, the concept of smart-pipe system is compared with the current monitoring systems for a water distribution system, and a method to quantify its benefit using the inconvenient time for customers is suggested. The suggested method was applied to a real water distribution system to estimate its applicability and benefit.

Damage of infrastructures by an earthquake causes the secondary damage through the world at large more than the damage of the structures themselves. Amomg them, underground utility tunnel structures comes under the special life line: communication, gas, electricity and etc. and it has a need to evaluate its fragility to an earthquake exactly. Therefore, the destruction ability according to peak ground acceleration of earthquakes for the underground utility tunnels is evaluated in this paper. As an input ground motion for evaluating seismic fragilities, real earthquakes and artificial seismic waves which could be generated in the Korean peninsula are used. And as a seismic analysis method, response displacement method and time history analyzing method are used. An limit state which determines whether destruction is based on the bending moment and shear deformation. A method used to deduct seismic fragility curve is method of maximum likelihood and the distribution function is assumed to the log normal distribution. It could evaluate the damage of underground utility tunnels to an earthquake and could be applied as basic data for seismic design of underground utility tunnel structures.

People use diary or photograph for recall-ing their memory in order to satisfy their desires for recording their lives. If the experienced events are organized to a story, S/he can share her/his experience with others, and recall her/his significant events easily. In this paper, we propose a method that generates a story with Petri net and user contexts collected from mobile device. Here, we use Petri-net as a representation method that links human activities or experience causally. It is appropriate solution for modeling parallel events in real world, and for representing non-linear story line. In order to show the usefulness of the proposed method, we show an example of generating a story of user's experience with user contexts from mobile device and evaluate them.

Lifeline Damages induced by earthquake loading brings not only a structure damage but the communication problems by the interruption of various energy utilities such as electric power, gas, and water resources. Earthquake loss estimation systems in USA and Japan, called as HAZUS (Hazard in US) and HERAS (Hazards Estimation and Restoration Aid System), respectively, have been established for the purpose of efficient responding to the earthquake hazard. Sufficient damage records are required to establish these systems. However, there are insufficient data set of damage records obtained from previous earthquakes in Korea. In this study, according to the construction specifications of the pipelines in both Korea and USA, the behavior of both ductile and brittle pipelines embedded in dense sand overlying various soils, such as clay, sand, and gravel were examined with respect to the pipeline characteristics under various earthquake loadings. The applicability of pipeline damage prediction used in HAZUS program to Korea has been investigated.
