In this paper, we propose the organization of a sensor system and user's intent detection algorithm for walking assist rehabilitation robots. The main purpose of walking assist rehabilitation robots is assisting SCI patients to walk in normal environment. To use walking assist rehabilitation robot in normal environment, it is needed to consider various factors about user's safety and detection of user's intent and so on. For these purposes, we have analyzed the use case of rehabilitation robots and organized the system of sensors for walking assist rehabilitation robots and finally, we have developed the algorithm which is used to detect user's intent for those. We applied our proposal method in the rehabilitation robot, ROBIN, and verified their effectiveness by normal, not patient.

Objectives: This study aimed to provide basic data for future development and promotion of oral health care educational material. We examined the perception of teachers and parents on the use of smartphone applications as educational materials and the factors affecting the intent to use such materials in infants and toddlers. Methods: Teachers and parents of children enrolled in educational institutions in Seoul and Gyeonggi Province, Korea, participated in this study for a one-month period starting from August 2018. Results: The intent to use a freely available smartphone application for oral health education in infants and toddlers was high for both parents and teachers at 81.7% and 78.4%, respectively. The intent to use increased 10.089-fold when a child had unrestricted access to mobile devices, and 4.435-fold when the execution path required modification; however, the ease of use was not compromised. Additionally, the intent to use also increased 2.488-fold when a child had used an educational oral healthcare material that is currently available, and by 2.431-fold and 2.219-fold when a child had previous experiences with an educational mobile application developed for infants and toddlers. Conclusions: Our findings showed that the teachers and parents had a positive perception towards the use of mobile applications for oral health care education in infants and toddlers. We recommend the development and promotion of mobile-based educational applications on oral health care, which are tailored to the needs and oral characteristics of infants and toddlers to help develop good oral care habits.

Purpose - Inducing consumers' behavioral intent to use an outlet shopping center is a critical issue for managers since it can be used as a guide for developing marketing strategies. Low prices could lead to a growth in retail purchases, but there might also be a positive relationship between prices and customer perceptions of product quality. The extent to which consumers use price as a predictor of quality may differ according to the availability of important alternative cues such as brand, store name, and identity salience triggered by the store. Consumers can obtain non-economic benefits from marketing exchanges that go beyond basic economic achievement. We argue that identity salience can play a crucial mediating role when consumers, acting as exchange partners, seek to obtain social benefits. This study shows that identity salience could mediate the relationship between identity salience-inducing factors such as multi-finality, prestige and role performance, and consumers' behavioral intent to use an outlet shopping center. Research design, data and methodology - The survey was conducted on college students enrolled in marketing classes. A total of 200 questionnaires were distributed, of which only 194 were returned. After five incomplete questionnaires were excluded, a final sample of 189 was used for empirical analysis. Using a covariance structural analysis in Amos17, we confirmed the fit of the research model and estimated its parameters by using the maximum likelihood method. Results - The results of the hypotheses testing are as follows. First, both identity salience and economic benefits have positive effects on the behavioral intent to use an outlet shopping center. Second, role performance, prestige, and multi-finality have positive effects on identity salience. Finally, the additive analysis of the direct effects of identity salience-inducing factors shows that the role performance, prestige, and multi-finality factors have no direct effects on the behavioral intent to use an outlet shopping center, suggesting that identity salience plays a positive mediating role. Conclusions - This study informs marketers that not only price but shoppers' identity salience directly affects their intent to visit an outlet shopping center. To strengthen shoppers' identity salience, marketers should find ways to help shoppers fulfill their multiple social roles, realize their multiple goals, and achieve prestige. In other words, outlet shopping centers must improve their personal service environment in order to enhance their employees' service quality and assist the execution of multi-finality by minimizing the perceived costs (e.g., travel time, effort) associated with shopping trips, thus making it easier for consumers to combine visits to multiple stores in outlet shopping centers and buy the items required for their consumption goals. Outlet shopping centers must also offer assortments with both breadth and depth in order to help consumers play the social roles their social networks have given them.

Purpose: The purpose of this study was to compare hospitalized patients in comprehensive nursing care units and general care units as to satisfaction with nursing care and factors influencing their intent to revisit the hospital. Methods: A cross-sectional study was conducted with 178 patients who had been hospitalized in a comprehensive nursing care unit and a general care unit in one hospital. Participants completed self-report questionnaires. Data were analyzed using SPSS 21.0. Results: There was a significant difference between the comprehensive nursing care unit and general care unit for intent to revisit the hospital (p=.036). Factors influencing intent to revisit the hospital for patients in the comprehensive nursing care unit were 'satisfaction with nursing care' (p<.001) and 'use of additional costs for comprehensive nursing care' (p=.041). The factor influencing intent to revisit hospital for patients in the general care unit was 'satisfaction with nursing care' (p<.001). Conclusion: Findings indicate that comprehensive nursing care service in which all care is provided by nursing staff only, without family or private caregivers, increases intent to revisit the hospital. These results can be used as the foundation of reviewing the operation and expansion of comprehensive nursing care service.

This research is an empirical investigation into the dimensions determining the website quality of domestic online shopping malls. A research model that has been formed to find the website quality dimensions is based on DeLone and McLean's information system success model that we adapted to fit the B2C electronic commerce environment by incorporating existing research on IS service quality and website quality. The model incorporates three quality dimensions including the information quality, system quality and service quality, and an attempt was made to empirically examine the relationship between variables of these dimensions and the revisit intent. The results of the study revealed that five quality-related variables were found to importantly contribute to the user's intent to revisit a site : the information accuracy and relevancy, system reliability, ease of use, and on-line support. The paper concludes that the three quality dimensions can serve as a useful framework to evaluate the quality of online shopping mall websites in an attempt to improve the website revisit rate.

정보기술 아웃소싱의 확대와 함께 최근 들어 아웃소싱을 전술적인 의도가 아닌 전략적인 의도에서 바라보며 비즈니스에 미치는 효과를 최대화하고자 아웃소싱을 추진하는 기업이 증가하고 있다. 이에 따라 다양한 형태를 보이고 있는 아웃소싱의 의도 결정에 영향을 미치는 요인에 대한 연구의 필요성이 제기되고 있다. 아웃소싱 의도는 선행 연구에 따라 정보시스템 개선, 사업에의 영향, 상업적 이용으로 분류하였고, 이러한 아웃소싱 의도를 결정하는 요인으로 조직 전략 유형 및 정보기술 역할 그리고 이들 간의 상호작용을 채택하고, 이들 요인이 아웃소싱 의도 결정에 미치는 효과를 보다 명확하게 파악하고자 조직 규모 및 정보기술 성숙도를 조절변수로 채택하였다. 분석 결과 정보기술의 역할보다는 조직의 전략이 아웃소싱 의도 결정에 영향을 미치는 것으로 밝혀졌다. 조직의 전략 유형 중 방어자는 분석자와 수동적 반응자에 비해 정보시스템 개선을 위한 의도로 아웃소싱하는 정도가 높았다. 또한 탐색자의 경우에는 분석자 및 수동적 반론-자에 비해 상업적 이용을 위한 의도로 아웃소싱하는 정도가 높았다. 이는 조직의 전략적 특성이 아웃소싱 의도에 반영되는 것으로 볼 수 있다. 정보기술의 역할에 따라 아웃소싱 결정이 달라진다는 선행 연구가 있지만, 정보기술의 역할에 따라 아웃소싱 의도가 달라진다고 보기는 어려운 것으로 밝혀졌다. 또한 조직의 전략 유형 및 정보기술 역할 간 상호작용에 따라 아웃소싱 의도가 달라진다고 보기는 어려운 것으로 나타났다. 아웃소싱 결정을 내리게 될 때 조직의 전략을 적극적으로 파악 및 반영하여 아웃소싱의 의도를 분명히 한다면, 아웃소싱의 실패 위험을 낮추고 성공 가능성을 높여주게 될 것이다.

현재 스마트폰 사용자의 증가에 따른 영향으로 스마트폰 기반의 악성코드가 많이 발견되고 있다. 그 중에서 안드로이드(android) 악성코드의 개체수가 많은 것은 사용자와 개발자에 대한 개방형 정책과 시스템 접근의 용이성에서 원인을 찾을 수 있다. 인텐트(intent)는 안드로이드 어플리케이션간의 메시지 객체를 전송하여 해당 컴포넌트를 사용할 수 있게 하는 통신 매커니즘이다. 인텐트의 이용은 기존에 존재하는 컴포넌트를 재사용하여 개발자에게 편의성을 제공하지만 보안적인 측면에서는 취약점으로 활용될 수 있다. 인텐트의 보안 취약점은 어플리케이션의 주어진 고유 권한을 임의로 사용 가능하게하고 의도한대로 어플리케이션을 제어할 수 있다. 본 논문에서는 스마트폰 이용자가 커스텀 커널(custom kernel) 사용에 따른 인텐트 보안 취약점에 대해서 대응한다. 브로드캐스트 인텐트의 취약점은 브로드캐스트 리시버에 주요 인텐트를 등록하여 탐지와 차단을 한다. 또한 검증되지 않은 인텐트의 접근 흐름을 실시간으로 감시하여 보안 취약성을 탐지하는 기법을 제안한다.

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is everywhere. This research explores whether and how travelers' upfront exposure to a CAPTCHA influences their subsequent behaviors. In the travel decision-making context, we investigated the relationship between CAPTCHA and travelers' hotel preferences and intent to use cryptocurrency during the trip. In two experimental studies, we found that travelers exposed to a CAPTCHA (vs. not) preferred a robot-staffed to a human-staffed hotel (Study 1) and a pro-environmental to a quality hotel (Study 2). Exposure to a CAPTCHA also influences travelers' intent to use cryptocurrency during travel (Study 2). Preference for a pro-environmental hotel does not depend on the formats of CAPTCHA ("I am not a robot" or "I am human") while intent to use cryptocurrency is higher when travelers were exposed to the "I am not a robot" than "I am human" CAPTCHA. The results of two exploratory studies suggest several potential mechanisms by which CAPTCHAs affect travelers' behaviors and call for more research on this topic.
