The study reviews theoretical and empirical research literature in information needs, seeking and uses in order to search for the most pertinent metatheories for studying information practices of the disadvantaged. The study examines the salient features and main theories/models of each cognitive, affective and social approach in the user-centered paradigm through analyzing prior information practices studies. While analyzing the main features of each cognitive, affective and social approach, the study points out the limitation of research using the cognitive and affective approaches to fail to theorize the relationship between individuals and complex and dynamic socio-cultural contexts in information practices. As an alternative, the study suggests using the social approach as a pertinent metatheory for understanding information practices of the disadvantaged who are entangled with myriad social contexts and issues. In order to verify the pertinence, the study examines the advantages of the social approach through analyzing both the main models related to everyday information practices under social constructionism and the main findings from information practices of the disadvantaged.

This study purposes to analyze how the level of diversification affects cost stickiness behavior. Specifically, we document that cost stickiness behavior is bigger in case of firm with a high level of related diversification. The purpose mentioned above are empirically tested using 1,508 firm-year data listed on Korea Stock Exchange from 2000 to 2009 and regression analysis methods were used for the analysis of the research hypotheses. The following are the results of this study : First, the increase in SG&A(selling, general and administrative costs) as sales increases is greater than the decrease in SG&A in respect to the equivalent decrease in sales. Second, cost stickiness behavior is bigger in case of firm with a high level of diversification. Also, cost stickiness behavior is bigger as the level of related diversification increase. These results imply that the level of diversification effects on the cost stickiness behavior.

사용자-제품 간의 인터랙션 환경의 변화로 인해 사용자 행태 정보의 특성을 체계적으로 분석하기 위한 많은 연구가 진행 되고 있으며, 사용자 행태 연구의 접근 가능성 보다는 행태 정보를 UI 디자인 과정에 어떻게 적용할 것인지에 대한 연구가 더욱 중요해 지고 있다. 이에 본 연구에서는 미래 제품 개발 환경에서 효율적인 UI디자인을 위하여 사용자의 실 생활에서 수집된 사용자 행태 정보를 UI 디자인 설계 과정에 효과적으로 적용할 수 있는 모델링 방법을 제안하였다. 이를 위해 사용자 행태 정보가 갖고 있는 단계별 구조의 특성을 정의하고, 행태 정보의 구조 분석을 통해 미래 제품 개발 환경에서 제품 사용 단계별 적용 가능한UI 고려 요소 및 UI 해결 방안의 도출 과정을 가시화 시켜 주기 위한 UI 모델링 방법을 제안하였다. 사례 연구로 현재 현관문에서 발생하는 사용자 행태 정보에 UI 모델링을 적용하여 미래 환경에서 제공 가능한 GATE System의 UI 고려 요소 및 UI 해결 방안을 추출하여 적용 가능성을 제시하였다.

A number of studies and models have focused on collaborative information behavior (CIB) in various contexts as the importance of research on CIB is recognized in information behavior research. This study compared and analyzed the models of CIB developed by Prekop (2002), Reddy and Jansen (2008), Shah (2008), Karunakaran, Spence and Reddy (2010), and Yue and He (2010), and discussed the direction of future studies of CIB. The future research strategies for overcoming the limitation of previous studies and models on CIB are to extend research object and context, to do holistic research approach tracing complexity of CIB, and to debate and verify the models of CIB. In particular, it needs to modify and improve the models based on the empirical research for domestic context.

본 연구는 환경정책에 있어서 피규제자인 환경관리인들이 자신들의 권익을 보호하기 위해서 집단적으로 어떠한 행태를 나타내는가에 관해 분석하였다. 그리하여 관리인들이 정책과정에서 보여주는 집단적 대응행태를 알아보기 위해서는 전국환경관리인연합회의 활동을 중심으로 분석하였는데, 이는 비록 이 단체가 역사는 짧고 응답자들이 역할을 충분히 인정하고 있지는 않으나, 관리인이 권익보호를 위한 유일한 이익집단이라고 보았기 때문이다. 그리하여 이를 위해 연합회보와 문서들을

본 논문에서는 KOSPI 200 주가지수 선물의 만기효과와 베이시스의 행태를 체계적으로 헤지 의사결정에 반영하기 위한 몇 가지 방법을 실증분석하였다. 우선 베이시스의 동태적 운동형태를 명시적으로 설정하지 않고 통계적인 방법을 통하여 헤지해제시점이 선물만기에 접근함에 따라 베이시스가 변동되는 양상을 반영한 헤지비율을 산출한다. 그 다음에는 헤지기간 전체에 걸친 베이시스의 운동형태를 명시적으로 설정하여 이에 입각한 헤지비율을 계산한다. 명시적인 베이시스의 운동형태는 비확률적인 과정과 확률적인 과정으로 다시 구분하고, 이 각각에 입각하여 최적헤지활동을 결정한다. 모든 헤지활동은 가장 최근까지의 정보를 이용하여 사전적으로 미래 헤지기간에 대한 의사결정을 하게 된다. 그러한 헤지활동의 사후적인 결과는 베이시스 행태를 별도로 고려하지 않고 단순선형회귀분석만을 이용하여 산출된 헤지성과와 비교되고, 변동성 감소 및 손실감소의 측면에서 각 접근방법이 가지는 특징 및 효율성을 평가한다. 실증 분석 결과, 헤지의 성과를 제고하기 위하여 선물의 만기효과와 베이시스의 행태변화를 체계적으로 반영한 세 가지의 시도 중 어느 것도 위험-수익의 2차원적인 비교에서 베이시스의 행태변화를 명시적으로 반영하지 않은 전통적 단순회귀분석을 압도하지 못하였다.

It has reported that a median bus-stop island on an exclusive median bus lane (EMBL) has shortened a crossing distance unit, encouraged a pedestrian's illegal crossing, and increased the number of accidents in the area. This study presents (1) the analysis of inappropriate pedestrian crossing patterns collected on exclusive median bus corridors and (2) the estimated performance of safety barriers restraining the occurrence of those. Total 19,649 pedestrian crossing data collected at the 'Sookmyung-university' median bus-stop, and the inappropriate pedestrian crossing patterns among those were grouped in terms of time and space violations. Physical safety barriers restraining illegal pedestrian crossings were considered as an alternative, and its performance in safety was quantified through microscopic simulation with conflict analyses by using surrogate safety assessment model. The findings suggest the number of conflicts reduced be 24.9 percentages compared to the one of the present condition when the physical safety barriers are placed at each of the eight ends of the EMBL pedestrian crossing.

This study suggests the necessity of behavior analysis as changes to a park environment to reflect user desires can be implemented only by grasping the needs of park users. Online data (blog) were defined as the basic data of the study. After collecting data by 5 - year units, data mining was used to derive the characteristics of the time series behavior while the significance of the online data was verified through social network analysis. The results of the text mining analysis are as follows. First, primary results included 'walking', 'photography', 'riding bicycles'(inline, kickboard, etc.), and 'eating'. Second, in the early days of the collected data, active physical activity such as exercise was the main factor, but recent passive behavior such as eating, using a mobile phone, games, food and drinking coffee also appeared as a new behavior characteristic in parks. Third, the factors affecting the behavior of park users are the changes of various conditions of society such as internet development and a culture of expressing unique personalities and styles. Fourth, the special behaviors appearing at Olympic Park were derived from educational activities such as cultural activities including watching performances and history lessons. In conclusion, it has been shown that people's lifestyle changes and the behavior of a park are influenced by the changes of the various times rather than the original purpose that was intended during park planning and design. Therefore, it is necessary to create an environment tailored to users by considering the main behaviors and influencing factors of Olympic Park. Text mining used as an analytical method has the merit that past data can be collected. Therefore, it is possible to form analysis from a long-term viewpoint of behavior analysis as well as to measure new behavior and value with derived keywords. In addition, the validity of online data was verified through social network analysis to increase the legitimacy of research results. Research on more comprehensive behavior analysis should be carried out by diversifying the types of data collected later, and various methods for verifying the accuracy and reliability of large-volume data will be needed.

The purpose of this study is to discuss the direction of studies of information seeking behavior(ISB) by analyzing previous studies provided model of ISB. Studies were divided into 3 types in terms of factors, processes, or types/patterns of ISB and sub-analyzed by 9 aspects such as research method/ theoretical framework, context of ISB and vice versa. Korean research strategies for overcoming the limitation of ISB studies are to do holistic research approach capturing complexity and multidimention of ISB as well as to extend research objects. Also, it needs to construct substantive theories based upon korean phenomenon of ISB.
