스마트폰의 내장형 3축 가속도 센서를 이용한 사용자 행위 인식은 사용자 개개인의 행위 패턴이 모두 달라 사용자에 따른 의존성이 크고, 스마트폰의 위치나 방향이 일정하게 고정되어 있지 않기 때문에 센서 데이터를 토대로 서로 다른 행위들을 정확히 분류하는데 어려움이 있다. 본 논문에서는 특정 사용자나 스마트폰의 특정 위치에 대한 의존성이 적은 효과적인 행위 인식 방식을 제안하고, 이를 기초로 안드로이드 스마트폰 기반의 실시간 행위 인식 시스템을 구현하였다. 총 6642개의 데이터 집합을 이용하여 본 논문에서 제안한 행위 인식 시스템의 사용자 의존성 및 폰 위치 의존성 분석 실험을 수행하고, 그 결과를 소개한다.

Intelligent video analysis systems require techniques which can predict accidents and provide alarms to the monitoring personnel. In this paper, we present an abnormal behavior analysis technique based on adaptive background generation. More specifically, abnormal behaviors include fence climbing, abandoned objects, fainting persons, and loitering persons. The proposed video analysis system consists of (i) background generation and (ii) abnormal behavior analysis modules. For robust background generation, the proposed system updates static regions by detecting motion changes at each frame. In addition, noise and shadow removal steps are also were added to improve the accuracy of the object detection. The abnormal behavior analysis module extracts object information, such as centroid, silhouette, size, and trajectory. As the result of the behavior analysis function objects' behavior is configured and analyzed based on the a priori specified scenarios, such as fence climbing, abandoning objects, fainting, and loitering. In the experimental results, the proposed system was able to detect the moving object and analyze the abnormal behavior in complex environments.

The purpose of this study was to examine the relationship between depression, perceived health status, and health promotion behavior of frail elderly. The subjects were 164 frail elders aged over 65 registered with the home visiting services of two welfare centers in D city. Data was collected using structured questionnaires from January 2 to February 21, 2020. Data was analyzed using the t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and stepwise multiple regression with the SPSS/WIN 23.0 program. The mean depression score was 10.67, perceived health status was 6.71, health promotion behavior score was 2.59. Health promotion behavior and depression were negatively correlated and perceived health status was positively correlated. Factors influencing health promotion behavior were age, education level, and depression. These variables accounted for 73.6% of health-promoting behaviors. Based on these results, we conclude that it is important to continue health promotion for the frail elderly through various programs including interventions for depression to prevent the elderly from progressing to disability.

The web is a new information environment, which has different characteristics from a traditional IR environment. Needed are more research from a new point of view as well as the adoption of a new research paradigm in order to understand a user-system interaction on the web. The purpose of this study is to review and analyze models of web-based information seeking behavior, which Wang, Hawk ＆ Tenopir, Hsieh-Yee, Choo, Detlor ＆ Turnbull, Chun ＆ Cooper, Rieh, and Spink proposed. The comparative analysis indicates that web-based information seeking models are categorized into three area: interaction model, information seeking behavior model, and evaluation model, and that they are based on a multifaceted interaction and a nonlinear perspective.

The purpose of this study is to analyze character of animation, , on the basis of Greimas' semiotic theory. Animation consists of activities between characters shown in narrative. The characters' activities show their value system and meaning. Hierarchical value system is created in the process that unrevealed, latent value is generated and character's thought and activity enlarge their meanings by creating various relationships with other character. Form this viewpoint, the study tried to analyze systematic characteristic shown in animation character and meaning structure shown in correlation through Greimas' model actant and semiotic square model.

This study focuses on the characteristics of information seeking behavior through the casual interactions which are regular contacts with others as information sources in the context of ELIS. Qualitative data were gathered using semi-structured one-to-one interviews with 9 wild-goose mothers in order to investigate the casual interactions. We identified information needs, patterns and characteristics of information seeking behavior through the casual interactions and the major interpretative repertoires.

연구 목적: 1980년대 이후 미국 여성들의 유방암 조기 진단을 위한 방사선 검진율은 급속히 증가하였음에도 불구하고 유색 인종의 여성들은 여전히 조기 검진의 혜택을 받지 못하고 있다. 유색인종 여성들의 낮은 검진율을 설명하기 위해 여러 건강행위이론을 이용한 관련 요인들이 연구되어 왔다. 이 논문은 미국 보건 의료관련 연구에서 가장 많이 쓰이는 다섯 건강행위 이론을 유색 인종 여성, 특히 한국 이민 여성들의 유방암 조기검진 이행에 적용하기 위해 사회문화적 적합성을 평가하기 위해 고안되었다. 연구 방법: 네 종류의 데이터 베이스(CINAHL, MEDLINE, PsycINFO, Sociological Abstracts)를 이용한 심층적 문헌 고찰을 통해 각각의 이론으로 유방암 조기 검진을 설명한 연구들을 모두 분석하였다. 연구 결과: 각 이론들의 배경, 주요 요인, 그리고 유색인종의 유방암 조기 검진에서의 적용 연구 등을 분석하였다. 결론: 서양 문화권 속에서 개발된 각 이론들이 한국적 정서와 행동을 설명하는데 명확한 한계가 있으며 이러한 한계를 극복하기 위해서는 기존의 이론들을 면밀하게 재분석하여 한국적 특성을 담아낼 수 있는 새로운 이론의 도출이 요구된다.

This study examined the type of needs involved in the activities of a virtual community and the impart of gender on online participants' needs and 'perceived control behavior'. In addition, the study tried to figure out how people behave on certain factors. The survey was conducted to 230 local students who have experienced online community activities. The study results showed there were three factors related to a virtual community, 'relational need', 'entertainment need', 'instrumental need'. There was, however, no significant effect between gender and the type of needs, and between gender and 'perceived behavior control'. The results also showed that 'entertainment need' is the most important factor to predict a virtual community participation. This might not Imply the improvement of information technologies helps us return to the communities in which Individuals have a close and affectionate relationship each other.

This study aimed to provide basic data for the enhancement of health behaviors by examining relations among cardiocerebrovascular diseases knowledge, attitude, health behaviors among male workers in their 30, 40s, and then understanding factors having influence on health behaviors. Targeting male workers in their 30, 40s working for companies in J & S cities, a survey was conducted by using tools for the knowledge, attitude, and health behaviors. The data were analyzed with SPSS Win 21.0 program. In the results, Knowledge and attitude showed positive correlations with health behaviors. As factors having influence on targets' health behaviors, there were the knowledge of cardiovascular, department, marital status in the order while the overall explanatory power was 14.8%. Based on this study, the educational implications of health behaviors for the prevention of cardiocerebrovascular diseases, and suggestions for the follow up research were presented.

Purpose: A descriptive study to focus the life style, self-efficacy and health promotion activity of university students, to analyze the phase-to-phase relationship between and impact on health promoting behaviors. Method: At K University among 225 students on 22-26th August 2014. Self-management and self-efficacy of [24] and health promotion activities of [29] are used for the measuring tools. Results: Health promotion activity with general characteristics is major, living and allowed time is a significant different. Between health promotion activity and self management of health variables were shown moderate correlation. Self-efficacy was too. The relevant explanatory factors influencing the self management of health promotion activities was found to be 64.0%. Conclusion: This study suggests that to improve the health promotion activities, measures to promote self-management and self-efficacy are required and the development of health promotion program is needed.
