  • 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.

  • It is possible but not efficient to model and simulate asynchronous microprocessors with the existing HDLs(HARDware Description Languages) such as VHDL or Verilog. The reason it that the description becomes too complex. and also the simulation time becomes too long to explore the design space. Therefore it is necessary to establish a methodology and develop a tool for modeling the handshake protocol of asynchronous microprocessors very easily and simulating it very fast. Under this objective an efficient CAD(Computer Aided Design) tool SLEDS(System Level Event-Driven Simulator) was developed which can evaluate performance of a processor through modeling with a simple description an simulating with event driven engine in the system level. The ultimate goal in the tool SLEDS is to fin the optimal conditions for a system to produce high performance by balancing the delay of each module in the system. Besides SLEDS aims at verifying the design through comparing the expected results with the actual ones by performing the defined behavior.

  • The purpose of this study was to examine differences in motivation of the tourists, who visited the Daegu Ole Palgong mountain courses, according to the slow tourism tourists' demographic characteristics and use-behavior, and to examine the relationships between motivation and the degree of satisfaction of tourists and behavioral intention. Also, it was to present motivations and characteristics of slow tourism tourists and the accompanying managerial implications. In order to achieve this research purpose, a survey was conducted from May 8, 2010 to May 23, 2010 on the tourists who visited Daegu Ole Palgong mountain courses. The results of testing the hypotheses through empirical analysis were as follows. First, differences in motivations according to demographic characteristics and demographic characteristics and the use behavior of the tourists were partially adopted. Second, there were significantly positive (+) relationships between the motivations of visitors to the Daegu Ole Palgong mountain courses and the overall degree of satisfaction. Finally, the overall degree of satisfaction with the visits to Daegu Ole Palgong mountain courses had significantly positive (+) relationships with revisit intentions. These imply that it is necessary to provide differentiated strategies and programs and inducing strategies in accordance with the results presented. as well, marketing strategies to enhance the degree of satisfaction of the tourists should be considered.

  • This study was performed to analyze the relationship between the participative motivation and satisfaction of adolescents participating in Green Camp which was the field centered forest experience camp as analyzing the factor of the participative motivation and its influence on the satisfaction. Also, this study identified the changes in creative personality before and after participation to Green Camp. In results, there were five motivation factors: 'Adventure and Interest', 'Forest Activity', 'Improve Physical Health', 'Rest', 'Suggestion'. When respective factors were analyzed, the mean of 'Interest and adventure' was the highest at 4.303, and then 'Forest activity' at 4.287, 'Rest' at 3.970 followed. In the case of participant satisfaction, 'the teaching materials and tools of the camp' was the highest at 4.530, and then 'contents of the camp' at 4.410, 'lecture performer of the camp' at 4.229, 'the way of progress of the camp' at 4.036, 'the place of the camp' at 3.952, 'the passage time of the camp' at 3.843 followed. It showed that 'Forest activity' factor and satisfaction had a positive relationship (p<0.05). In addition, the means of creative personality before-and after-program participation increased from 3.687 to 3.773 (t=-2.218, p=0.029). Based on the analysis of satisfaction, this study suggested improvements of Green camp. Also, it proved that the participation Green camp had influence on the creative personality. The finding of this study is meaningful in that it proposed the necessity of activation forest education focusing on experience.

  • In this study, the effects of STAD cooperative learning strategy on students' achievement, learning motivation, perceptions of learning environment, and perceived classroom goal structure were investigated in terms of students' collectivism level. Two classes (64 students) from an elementary school were respectively assigned to a control group and a treatment group. A individualism-collectivism test, a learning motivation test, a perceptions of learning environment test, and a perceived classroom goal structure test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. After instruction, an achievement test, the learning motivation test, the perceptions of learning environment test, and the perceived classroom goal structure test were administered. The results indicated that the students of the treatment group significantly outperformed those of the control group in the achievement test. There was a significant treatment-aptitude interaction effect in the scores of the attention subcategory of the learning motivation. In the perceptions of learning environment, the score of the treatment group was significantly higher than the control group in the cohesiveness subcategory, whereas the score of the treatment group was significantly lower than their counterpart in the competitiveness subcategory. It was also found that the score of the treatment group was significantly higher than the control group in the performance subcategory of the perceived classroom goal structure.

  • This study examined several characteristics such as the relationships between environmental attitudes and national park visitors' socio-economic characteristics, and between environmental attitudes and their travel motivations. Environmental attitude was measured using the modified New Environmental Paradigm(NEP) scale, where five response options existed(from strongly disagree to strongly agree). Data for this empirical analysis were obtained from 2,647 participants at six national parks-Sulaksan, Kayasan, Naeiangsan, Pookhansan, Taeanhaean, and Hanryohaesang. Results showed that most visitors gave a pro-NEP response ranging from neutral attitude to pro-environmentalism. Environmental attitudes correlated positively with education level, while, negatively with age. Environmental concern, also, generally correlated positively with 'rest' and 'health' motivators, while, negatively with 'socialization' and 'vacation' motivators. The findings of this study suggest that education is the most effective politic measure to lead pro-environmental concern for park visitors. And, given the nature of the relationship between environmental concern and visitors' motivation, park managers should be more careful handling with family and group visitors who have 'vacation' and 'socialization' motivators than 'rest' and 'health' motivators.

  • Empathy has been observed to be pivotal in enhancing both social relations and the efficiency of task performance. Empathetic interaction has been shown to begin with individuals mirroring each other's facial expressions, vocal tone, actions, and so on. The internal responses of the cardiovascular activity of people engaged in empathetic interaction are also known to be synchronized. This study attempted to objectively and quantitatively define the rules of empathy with regard to the synchronization of cardiac rhythm between persons. Seventy-four subjects participated in the investigation and were paired to imitate the facial expressions of their partner. An electrocardiogram (ECG) measurement was taken as the participants conducted the task. Quantitative indicators were extracted from the heart rhythm pattern (HRP) and the heart rhythm coherence (HRC) to determine the difference of synchronization of heart rhythms between two individuals as they pertained to empathy. Statistical significance was confirmed by an independent sample t-test. The HRP and HRC correlation(r) between persons increased significantly with empathy in comparison to an interaction that was not empathetic. A difference of the standard deviation of NN intervals (SDNN) and the dominant peak frequency decreased. Therefore, significant parameters to evaluate empathy have been proposed through a step-wise discrimination analysis. Empathic interactions may thus be managed and monitored for high quality social interaction and communication.

  • The purpose of this study was to investigate the influences of impulsivity, family' gambling and the distance from the gambling facilities, on adolescents' gambling activity, gambling belief and gambling motivation in the future. A total of 567 high school students in Jeongseon and Taeback(the Kangwon-Land Casino area or near the Kangwon-Land Casino), in Gwhachoen City(near the Seoul Race Park), and in Whachoen(far from the gambling facilities area) were participated in this study, and completed the questionnaires for measuring adolescents' gambling activity, gambling belief and gambling motivation in the future, impulsivity and family gambling behaviors. Results showed there were positive relationships impulsivity, family' gambling, adolescents' gambling activity, gambling belief and gambling motivation in the future. There were significant relationships among dwelling areas, gambling behaviors, and beliefs. Especially, adolescents in Jeongseon have more likely gambling behaviors, and the gambling beliefs were more dysfunction than ones in Gwhachoen and Whachoen. And adolescents in Whachoen had the lowest gambling motivation. Also, the correlation between the impulsivity and gambling-related behaviors was significant. The implication of this study was as fellow. When planing the politic intervention for preventing the problem gambling in the future it was necessary to consider the distance from the gambling facilities as environmental component and impulsivity as personal component.
