블로그와 관련된 초기의 연구들은 주로 블로그를 사용하는 사용자를 동질성을 지닌 그룹으로 보고 연구를 진행하였다. 하지만 최근 블로그 인구가 크게 증가하여, 더 이상 동질성을 지는 그룹으로 보기에는 한계가 있다. 본 논문에서는 블로그 사용자(이하 블로거)를 구분하는 특성 요인을 추출하여, 블로거 세분화 작업을 수행한다. 세분화된 블로거 그룹의 전자상거래 이용행태, 콘텐츠 유료 구매 등과의 연관성을 분석하여 다른 인터넷 유저들과의 상대적 가치에 대해서 평가해보고자 한다. 또한 분석된 블로거 그룹의 특성을 활용하여, 하위 블로거의 상위 블로거로의 전환요인이 무엇인지에 대해서 탐구해보고자 한다.

Based on two cross-sectional Time Diary data. this study examines the change in internet use pattern of Koreans. Building on the literatures on Digital Divides, it traces the changes in frequency, diversity and specific purpose of internet use and tries to identify factors affecting these changes. The results show that the frequency and diversity of internet use increases across five years. They also reveal that the usage gap in internet between genders increases While the usage gap across social economic status still exists. The implication of these results are discussed.

The position information of individual vehicles on a road at every time instant can be used to analyze the microscopic behaviors of driving of each vehicle. The limited information obtained from previous imaging technology such as traffic volume and interval velocity cannot be used to explore such microscopic traffic conditions. Also, information gathering for the microscopic behaviors by manual analysis of captured video takes large amount of time and man-power. In the paper we develop the rule-based vehicle tracking technology from which the position information of individual vehicles on a road at every time instant can be automatically obtained. Also, we extract the position data of driving vehicles on a road, length of 130m for every 0.05 second, and calculate the velocity of each traced vehicles to compare with the real velocity for the verification of accuracy. In the future, this type of tracking techniques based on video analysis can be widely used to provide the practically important information of road traffic conditions and to analyze the academically important microscopic behaviors of driving patterns.

So far, the behaviors of Web users have been predicted or analyzed mostly by their demographic characteristics or by considering in which context they gain access to that. But now there is a question about whether those characteristics are the only factors to trigger their use of Web. If the answer is not affirmative, what types of additional factors could cause such an action and how they characterize it should be discussed. User profile information has been considered one of the crucial elements to define user characteristics in user-centered UI design sector, and in order to apply it to UI design, it's needed to meditate on the above-mentioned questions. In this study, it's first attempted to have a good understanding of the users of different media and to review existing user classification methods. Next, user classification variables and relevant scales were prepared to sort out users according to their type of using Web, and case study was conducted to identify the behavioral characteristics of users and classify them according to their behavioral features. Finally, the user profile features of individual user groups were figured out based on data that were gathered by making an experiment, and data mapping was fulfilled between the behavioral characteristics and user profile characteristics to find out what types of behaviors were caused by the characteristics of user profile. As a result, it's found that user characteristics could have an impact on not only their general information and relevant contexts but their attitude of using different media and personality type. There were some problems with the experimental design, but more accurate information on the relationship of user behaviors to user profile characteristics will be obtained if those problems are eliminated. As user behaviors could be predicted only by user profile characteristics, user classification is expected to make a contribution to enhancing the efficiency of UI design.

스마트폰의 확산과 함께 소비자들의 소비 환경과 행태가 변화하면서 기업은 온라인과 오프라인을 연계하는 O2O 서비스를 제공하고 있다. 기존의 O2O 서비스는 제품 정보를 기반으로 온라인 쇼핑을 제공하고 있으나 온 오프라인 매장 간의 연동에 한계가 있다. 이에 본 논문에서는 온라인 쇼핑몰, 오프라인 매장을 통합하여 상품에 대한 정보 제공과 제품 판매 서비스를 제공하기 위해 스마트 피팅 시스템을 활용한 O2O 연계시스템을 제안한다.

가상화 기반 클라우드 컴퓨팅 환경은 비용 효율성과 자원 활용 측면에서 강점을 갖고 있으나 주어진 응용의 행태에 따른 적절한 자원할당 방법이 필요한 상황이다. 그러므로 클라우드 컴퓨팅 환경에서 다양하게 구성된 가상클러스터와 응용 특성을 서로 비교 분석해야 한다. 이를 위해 본 논문의 목적은 OpenStack 기반 가상화 자원을 사용하여 생성된 클러스터 환경을 상태분석 도구인 Ganglia를 이용하여 분석한다. 분석에 사용되는 Utility 함수의 결과는 각 응용에서 요구되는 성능을 클라우드 컴퓨팅 환경이 만족시키는지 판단할 수 있는 자료가 될 것이다.

This study aims to compare information seeking behavior of 1300K users on PC and mobile phone. Transaction logs of 1300K, a major Korean shopping search engine, were analyzed. These transaction logs were collected over 1 month period, from April 1 to April 31, 2016. The results of this study show that there are a little more mobile sessions than PC sessions. Users conducted slightly more browsing on PCs than mobile phones, whereas users submitted queries more than two times on mobile phones than on PCs. Users clicked more search results on PCs than mobile phones, whereas users made important decision makings such as product purchases more on mobile phones than PCs. Top queries and categories were similar between PCs and mobile phones. Queries and categories on mobile phones were more focused than queries on PCs. Overall, mobile search behavior is more simple, passive, and focused than PC search behavior. The results of this study can be implemented to the effective improvement and development of search services for different devices.

유선 인터넷에서 인스턴트 메신저는 간단한 질문/확인, 만남이나 작업 조정, 사회적인 친교 등을 위해 광범위하게 활용되고 있다. 이를 무선으로 확장하기 위하여 MSN, Yahoo, AIM, ICQ, 버디버디, 네이트온 등이 모바일용 메신저를 내놓고 있다. 특히 한국 10대의 경우 SMS를 실시간 대화에 가깝게 (짧고 빈번하게) 사용하고 있기 때문에 무선 메신저는 큰 호응이 있으리라 예상하였다. 그러나 네이트온 모바일 메신저의 경우, 2002년 출시된 이후 별다른 인기를 끌지 못하고 있다. 이에 저자들은 네이트온 사용자들의 사용행태를 분석하여 문제점을 파악하고, 일반 SMS 사용자들과 네이트온 사용자들의 무선 커뮤니케이션 사용행태를 1주일간의 Diary Study에 기초한 Contextual Inquiry (Intermittent)를 실시하여 사용률이 저조한 이유를 분석한 뒤, 퍼소나를 구성하여 무선 환경에 맞는 완전히 혁신적인 새로운 형태의 무선 메신저 사용자 인터페이스를 설계하였다. 메신저에 반드시 있는 사용자 등록이나 친구 추가 기능을 없애고 휴대전화 번호 기반으로 동작하며, 상태 정보(Presence)를 없애면서 상대방 상태에 따라 IM 혹은 SMS로 적절히 변환되어 전달되는 것이 주요 특징이다. 이를 사용자들을 통해 다시 검증해 본 결과 사용자들이 무척 쉽게 받아들이는 것을 발견하였다.

There have been studies on the satisfaction, preference, and post occupancy evaluation of urban parks in order to reflect users' preferences and activities, suggesting directions for future park planning and management. Despite using questionnaires that are proven to be affective to get users' opinions directly, there haven been limitations in understanding the latest changes in park use through questionnaires. This study seeks to address the possibility of utilizing the thirdgeneration SNS data, Instagram and Google, to compare behavior patterns and trends in park activities. Instagram keywords and photos representing user's feelings with a specific park name were collected. We also examined reviews, peak time, and popular time zones regarding selected parks through Google. This study tries to analyze users' behaviors, emerging activities, and satisfaction using SNS data. The findings are as follows. People using park near residential areas tend to enjoy programs being operated in indoor facilities and to like to use picnic places. In an adjacent park of commercial areas, eating in the park and extended areas beyond the park boundaries is found to be one of the popular park activities. Programs using open spaces and indoor facilities were active as well. Han River Park as a detached park type offers a popular venue for excercises and scenery appreciation. We also identified companionship characteristics of different park types from texts and photos, and extracted keywords of feelings and reviews about parks posted in $3^{rd}$ generation SNS. SNS data can provide basis to grasp behavioral patterns and satisfaction factors, and changes of park activities in real time. SNS data also can be used to set future directions in park planning and management in accordance with new technologies and policies.
