서비스 로봇의 지각과 행동에서의 신뢰성은 각 개별 요소기술의 완벽함으로부터 얻어지는 것이 아니라 비록 성능이 불완전한 요소기술들을 사용하더라도 각 요소기술들의 정보를 융합하고 능동적인 행위를 발생시키는 시스템적인 접근방식으로부터 얻어진다. 그러므로 본 연구에서는 자연스러운 HRI 구현을 위하여 "로봇인지 엔진"이라는 독창적인 통합 구조를 제안하였으며, 비동기/병렬 정보처리 구조, 다양한 지각정보들의 융합, 행위 결합을 위한 능동적인 지각정보 수집의 특징을 갖는다.

Maintaining active users who repeatedly share high-quality knowledge is critical for the success of online Q&A sites. This study suggests two paths that lead to active users' continuous knowledge sharing: 1) elaborated decision process, represented by continuance intention, and 2) automated cognitive process, represented by past behavior. The direct and moderating effects of continuance intention and past behavior were verified by analyzing subjective intention data and objective behavior data of 333 active users of Naver Knowledge-iN. Using Cox proportional hazards regression and negative binomial regression, the influences of continuance intention and past behavior on two types of continuous knowledge sharing were examined. The results showed that only past behavior was significantly influential on knowledge sharing continuance and as to the frequency of knowledge sharing, both continuance intention and past behavior's influences were significant. It was also confirmed that past behavior negatively moderates continuance intention's effect on the frequency of knowledge sharing. In order to maintain active users' continuous knowledge sharing, it is important to habituate knowledge sharing through repetitive knowledge sharing behavior. And in order to increase the frequency of knowledge sharing, in addition to the habituation, appropriate benefits that can increase the continuance intention should be provided.

The main purpose of this study was to treat pica in a 2.8 year old child with severe mental retardation along with autistic tendencies. His developmental age ranged from 12 to 15 month on the DDST and he had no means of communication. He was on Tegretol 200mg for seizure control. His pica involved thumb sucking, putting toys into his mouth, and licking furniture wherever he went Besides pica, he had a rumination problem. The treatment strategies for his pica consisted of two phases : In phase 1, The child was taught toy play through a 3-step guided compliance training, while his pica and rumination behaviors were recorded to investigate whether active toy play could effect any change in the untreated pica and rumination behaviors of this child. In phase 2, a facial screening was used as a means to control his pica, while his rumination was recorded to see whether controlling his pica could bring any change in the untreated ruminating behavior. The results showed that the facial screening was very effective in decreasing his pica from an average of 18.6 times per 15 minute in the baseline to 2.3 times post-treatment. Response covariation was observed across pica and rumination while toy play compliance training alone was being conducted, and covariation across rumination was observed while pica alone was being treated with facial screening.

The growth in smartphone service has given rise to an increase in frequency and importance of authentication. Existing smartphone authentication mechanisms such as passwords, pattern lock and fingerprint recognition require a high level of awareness and authenticate users temporarily with a point-of-entry techniques. To overcome these disadvantages, there have been active researches in behavior-based authentication. However, previous studies focused on enhancing the accuracy of the authentication. Since authentication is directly used by people, it is necessary to reflect actual users' perception. This paper proposes user perception on behavior-based authentication with feature analysis. We conduct user survey to empirically understand user perception regarding behavioral authentication with selected authentication features. Then, we analyze acceptance of the behavioral authentication to provide continuous authentication with minimal awareness while using the device.

The problem of the cases of Soribada and Winny is their duplexity that they could be used legally and illegally. The issue called 'The crime of aiding through the neutral behavior' is about whether the program developer who shared the file sharing program letting unspecified public infringe the copyright could be punished or not. Many theories about limiting the traditional scope of punishment of aider have been maintained. However, it is questionable whether it is possible to limit the scope of punishment following the former cases and theories even for the action that is causal and facilitates the principal's criminal conduct, like the aid through the neutral action which is hard to perceive as illegal aid because of its characteristics. Therefore, using the case of Soribada in Korea and the case of Winny in Japan as the examples of illegal aid through neutral behavior case, this paper examines the characteristics and problems of aid through existing theories and cases, and suggests new scope of punishment limitation standard through the elaboration of the action of aid and judgment of degree.

This study analyzed the effect of metacognition to the information-seeking behaviors of 250 undergraduate students. For this, metacognition was examined by the inspection form that the Educational Psychology Programs of the Department of Education, at Seoul National University, developed in 2005. The information-seeking behaviors were examined by the observance of the established information-seeking performances and through a survey. As a result of the analysis, metacognition affected the items of the survey for the information-seeking behaviors, excluding one item. As metacognition is the cognitive characteristics acting after the cognitive process, it affected thinking activities that were conducted by the brain. In addition, metacognition affected the seeking process, the results of seeking, and the general information-seeking behaviors. Therefore, the study of metacognition is effective in the overall aspects of information-seeking behaviors including the seeking process, the results of seeking, and the general information-seeking behaviors.

With the advent of the era of mass tourism in China and people's yearning for a better life, the demand for family tourism is increasing. This paper adds the filial piety concept variable to the original model based on the theory of planned behavior (TPB). It tests the influence mechanism of attitude, subjective norm, perceived behavior control and filial piety on the intention of family tourism behavior. The results show that； Attitude and subjective norms have significant influence on the intention of family tourism behavior; Perceptual behavior control has no significant influence on the intention of family tourism behavior; Mutual filial piety has a significant impact on family tourism behavior and authoritative filial piety has no significant effect on family tourism decision-making behavior. This conclusion expands the application boundary of the theory of planned behavior in the study of family tourism behavior intentions, and provides application reference for tourists and tourism enterprises.

The purpose of this study was to investigate relationship among sexual knowledge, sexual attitudes, and reproductive health promoting behaviors of nursing college students. The research tools utilized were sexual knowledge measurement tool by Jeon(2004), sexual attitudes measurement tool by Ho(2009), and reproductive health promoting behaviors measurement tool by Jo(2014). A total of 300 nursing college students were surveyed, and 229 responses were analyzed. Data analysis was performed using descriptive statistics, t-test, ANOVA, Scheffe's post hoc test and pearson's correlation coefficients with IBM SPSS Statistics 21.0. Female students exhibited higher sexual knowledge, and it was evident that reproductive health promoting behavior education is appropriate during lower academic years. Additionally, the indication that higher sexual knowledge corresponds to higher reproductive health promoting behaviors suggests the ongoing necessity for sexual education to enhance reproductive health promoting behaviors. Therefore, this study could serve as foundational data for developing educational materials on reproductive health promoting behaviors for counseling and education aimed at improving nursing college students' reproductive health.
