상황인지는 유비쿼터스 컴퓨팅 환경에서 사용자의 주변 상황을 인지하여 사용자가 원하는 서비스를 제공하기 위해 필요한 핵심 기술이다. 이러한 상황인지를 위해 여러 센서로부터 발생하는 저수준의 컨텍스트 정보를 처리하는 다양한 방법들이 존재한다. 그러나 현재 상황인지 처리에 관련된 표준 방법이 없어 서비스 도메인에 제한되고 복잡한 구현방법을 따라야 하며, 상황정보를 처리하는 시스템에 정형화된 상황정보를 제공하는데 어려움이 있다. 이에 본 논문에서는 정형화된 상황정보를 제공하기 위한 센터 데이터 변환 방법을 제안한다. 제안하는 센서 데이터의 변환 방법은 센서로부터 발생하는 저수준의 컨텍스트를 RDF 기반의 고수준의 상황정보로 변환하며, 변환된 정보는 상황인지 시스템에 제공된다.

본 연구에서는 스마트 디바이스를 이용하여 보행자의 상태를 감지하여 필요한 사용자의 정보에 대해 얻는 방법을 제안하고, 이를 분석하는 모델을 연구하여 예방 방안을 제공하는 서비스를 제안하였다. 분석 모델을 Sensing, Thinking, Action의 세 단계로 나누어 분류한 세부적인 수행 순서를 정하였다. Sensing 단계에서 센서, 디바이스, 어플리케이션 등을 통해 사용자에 대한 있는 그대로의 정보를 받아들여 디바이스가 인식하게 하고, 이를 분석해 사용자의 상태 및 상황에 대해 Thinking하고, 그에 맞는 Action을 취한다. 본 논문에서는 분석 모델의 정해진 수행 순서에서의 기능들을 설명하고, 그에 맞는 예상 구현 시나리오를 제시하였다.

The purpose of this study is to examine the presentation of Korean grammar on the Korean grammar textbooks for foreigners. Through the results, this study suggests some examples of grammar based on the discourse and context. Since the communicative approach received much attention, some Korean language forms have been researched in the discourse and context. In that sense, we need to survey the grammars presented in the grammar textbooks. The expressions of Korean epistemic modality and discourse function, ('-지요, -잖아(요), -군요', '-기는 하다') in the grammar textbooks have been analyzed. These expressions need to be described with much contextual and situational information and presented in the discourse. However it is a little insufficient to supply a proper amount of information for Korean language learners. To overcome the deficiency, this study presents some situational and contextual information of certain language forms.

In this study, we analyzed the factors that affect public awareness campaigns on social media platforms and developed an integrated model for measuring the persuasiveness of environmental social media campaigns. A survey questionnaire was created and distributed on Facebook with the goal of reaching individuals in their 20s and 40s in Vietnam, and 395 valid replies were gathered. The findings showed that the STOPS was reconfirmed as a suitable theoretical framework for analyzing the public's behaviour intention to conduct information related to the issue of fine dust, especially on social media. Furthermore, it also showed that social media efficacy has a moderating effect on the relationship between public's situational recognition and informational behaviour intention. This suggested that through social media platforms, personal characteristics play a vital part in developing effective environmental campaigns. Implications for both theory and practice were discussed.

Guide robots that provide services in public places have recently emerged as a non-face-to-face solution with the spread of COVID-19 and are growing. However, most guide robots provide only the same level of intelligence and the same interaction in different and changing environments. Therefore, its usefulness is limited and customers' interest is quickly lost. To solve this problem, it is necessary to develop social intelligence that can improve the robot's environment and situational awareness performance, and to continuously maintain customer interest by providing personalized and situational services. In this study, we developed guide robot services based on social HRI components that provides multi-modal context-aware. We evaluated service usefulness by measuring user satisfaction and frequency of use of the service through the survey. We analyzed the service quality attributes to identify the differentiating factors of guide robot based on social HRI components.

Due to the differences between and distinct consumer perceptions of domestic and cross-border e-commerce (CBEC), e-consumer misconduct, which we call "cunning behavior," has emerged. This study examines cunning behavior in CBEC and compares e-consumer perceptions about environmental factors and their own personal traits using a vignette experiment and survey. The vignettes of this study were developed for three situations: illegal, deviant, and unethical behavior. Drawing on vignettes, we collected survey data and then examined the research model using the analysis of moment structure statistical tool. The results show that perceived benefit and past experience with CBEC are strong triggers for cunning behavior, while the ability to exercise self-control restrains this behavior. This study provides an understanding of why cunning behavior occurs in the CBEC context and describes different cunning behavior types.

This study, as a experiment study, was intended to determine whether or not the situational leadership program was highly helpful to critical thinking, coaching, empowerment-enhancing of nurse managers. The number of subjects was abstracted by G*Power, and 54 nurses leader and 342 general nurses were selected from university hospitals of metropolitan city. Data analysis was frequency analysis, t-test, $X^2$-test, repeated measures ANOVA, using SPSS Win 18.0 statistical package program. The results of this study was as follows. 1. Due to the situation leadership programs, critical thinking of experiment group has significantly increased, but control group was significantly reduced. 2. Due to the situation leadership programs, coaching of experiment group has significantly increased, but control group was significantly reduced. 3. Due to the situation leadership programs, empowerment of experiment group has significantly increased, but control group was significantly reduced. Therefore, the situation leadership programs can be effective in critical thinking, coaching, empowerment of nurse leaders. And applying the situation leadership program to the nurse in future, it would be helpful promoting empowerment, coaching, critical thinking in organization life and cope with situation that occurred during clinical.

The purpose of this study was to explore convergence on the theory of unpleasant symptom, and factors affecting quality of life of liver cirrhosis patients. A total of 198 liver cirrhosis patients were recruited symptom experiences, physiologic factors, psychological factors, situational factors, and quality of life. Data were collected from March, to May, 2014 and analyzed using one-way ANOVA, Pearson correlations, multiple regressions analysis with PASW (SPSS) 21.0. Variables such as duration of liver cirrhosis(${\beta}=.19$, p<.001), symptom experiences(${\beta}=.19$, p=.032), physical(${\beta}=.15$, p=.008), psychological(${\beta}=.39$, p<.001) and situational factors(${\beta}=.32$, p<.001) explained 51.8% of variance in quality of life(F=15.57, p<.001). The symptom experiences, physiological, psychological and situational factors should be considered for caring liver cirrhosis patients. Symptoms of postmyocardial infarction (post-MI) patients at risk for progression to heart.

The aim of this study was to gain an understanding of the element playfulness in fashion photographs related to openness and multiple significance in contemporary art. A total of 105 fashion photographs from US and UK Vogue magazine editorials and advertisements for the last five years were selected for the study. The photographs were analyzed in two main categories - the contextual element of themes, and the elements of visual expression; composition, models, objects and editing technology. The element of playfulness in the photographs were found to be divided into themes of infantile fantasy, social satire and situational dissonance, and elements of visual expression were found to express image distortion, expansion, exaggeration, reduction, and optical illusions. A photography type termed as infantile fantasy and social satire have descriptive characteristics and usually deliver the message by using models and objects to present a certain situation or express social satirical viewpoint and reflective attitude by using objects and photographic skills. A photography type termed as situational dissonance is characterized by immediately understood expressions and usually clarify the message by using a photographic technology such as editing the printed image or expect the model to express an exaggerated poses and ridiculous expressions, causing an optical illusion. Visually expressed and composed scene using composition, models, objects and editing technology is a specific character of photograph and due to the advances in computer editing technology it has been able to express the various playfulness.
