본 논문은 실내 공간에서 RFID와 센서를 이용하여 이동로봇이 자기 위치를 파악하고 목표물체를 인식할 수 있는 기법을 제안한다. RFID를 지면과 목표물체에 설치하고 로봇은 리더기와 다양한 센서를 갖춤으로써 이동시 자기 위치를 파악하고 물체로부터도 고유정보를 얻을 수 있게 구성하였다. 초음파 센서 신호의 귀환시간을 활용하여 전방 물체의 거리를 추출하며 바닥의 RFID로부터 이미 획득한 자기 위치를 활용하여 물체의 절대 위치를 구한다. 이는 로봇을 중심으로한 경로지도를 실시간으로 작성하는 것이 가능하며, 실내의 구조 및 목표 물체의 위치등을 포함한 전체적인 지도를 작성할 수 있다. 최종적으로는 최적의 경로계획을 세워 로봇이 목표 위치로 이동하거나 자율적 탐색이 가능하도록 한다.

본 연구는 판매원의 판매노력을 효율적으로 일하는 것과 열심히 일하는 것으로 나누고, 판매노력이 목표수준과 성과에 어떠한 영향을 미치는지를 검증하였다. 그리고, 효율적으로 일하는 것과 열심히 일하는 것, 목표수준에 대한 선행요인으로 개인적 변수에 해당하는 경쟁심(경쟁기질)과 자기효능을, 환경변수에 해당하는 심리적 경쟁분위기와 판매관리자 신뢰도를 탐색하여 성과에 대해 간접효과가 있는지를 검증하였다. 보험설계사를 대상으로 설문조사하여, 265부를 실증분석 한 결과 열심히 일함은 목표수준에 영향을 미치며, 목표수준은 성과에 영향을 미치는 것으로 나타났으나, 효율적으로 일함과 열심히 일함의 성과에 대한 영향은 비유의적이었다. 매개변수(효율적으로 일함, 열심히 일함, 목표수준)에 대한 선행요인의 영향에 대해서는 개인변수인 경쟁심과 자기효능은 모두 유의적이었으나, 환경변수는 심리적 경쟁분위기만이 효율적으로 일함에 유의적이었다. 결과적으로 판매원의 성과에 대한 자기효능과 경쟁심의 효과는 열심히 일함 그리고 목표수준에 의해서 매개됨을 확인하였다.

Self-Organizing Map (SOM) is an unsupervised learning neural network and it is used for preserving the structural relationships in the data without prior knowledge. SOM has been applied in the study of complex problems such as vector quantization, combinatorial optimization, and pattern recognition. This paper proposes a new usage of SOM as a tool for schema transformation hoping to achieve more efficient genetic process. Every offspring is transformed into an isomorphic neural network with more desirable shape for genetic search. This helps genes with strong epistasis to stay close together in the chromosome. Experimental results showed considerable improvement over previous results.

For the research object of this study 112 university shooting athletes, registered with Korea Shooting Federation in 2014, have been selected. Statistics processing was carried out through SPSS 16.0 and AMOS 7.0. The following results were obtained by analysis of frequency, exploratory factor analysis, confirmatory factor analysis, correlation analysis and structural equation model analysis to serve it's purpose. First, task orientation had passive influence on self-management. Second, task orientation and ego-orientation had passive influence on perceived exercise performance. Third, self-management had passive influence on perceived exercise performance.

In order to analyze the influence of career self-efficacy on risk taking level in university students, career self-efficacy which becomes the basis of active occupational exploration was classified into four items including self evaluation, goal setting, occupational information and problem solving. Risk taking level was divided into three items of occupational selection, monetary management and human relation. 450 surveys were distributed to four-year university students in Seoul, capital area and rural area for three weeks from November 26 until December 17, 2011, among which 402 surveys were accepted as effective study subjects. Among items of career self-efficacy, most significant influence on self evaluation was shown in group with high risk taking level in monetary management, and problem solving had most significant influence in groups with high risk taking level in occupational selection and human relation. As a result, occupational information was found to have negative (-) influence on all items of risk taking level, with increasing degree of influence on occupational information for subjects showing lower degree of risk taking level. This study provides detailed analysis on individual's work task called risk taking level based on different occupational types, offering new verification of career self-efficacy as the most fundamental element of occupational exploration to university students looking for employment.

This paper was to examine the effects of university-based science gifted education program on scientifically gifted students' science problem finding ability and cognitive-affective factors. For this study, 69 scientifically gifted students with previous Silted education experiences at the university-based science gifted education centers and 91 scientifically gifted students without any previous gifted education experiences were compared. Both groups of students were currently enrolled at a specialized science high school. To compare both groups, scientific problem finding ability, science anxiety, science related attitude, self-efficacy, intrinsic motivation, test anxiety, cognitive strategies, and self-regulation were measured. The results indicate that there was no significant difference on scientific problem finding ability between these two groups. The comparison between the past and now in the aspects of variables observed in the study showed that both groups of students were decreased in the science anxiety and self-efficacy. But the test anxiety was significantly increased compared to the past in both groups. Implications of the study were discussed in depth.

This study examined the mediation effects of covert narcissism on the relationship between game addiction and aggression. For this study, 578 middle school boys in Chungcheong areas were included in the analysis. The results are as follows. First, correlation analyses showed that game addiction was positively correlated with covert narcissism and aggression. In addition, covert narcissism showed positive correlation with aggression. Second, step-wise regression analyses were conducted to examine the relative size that sub-factors of game addiction and covert narcissism explained aggression. It could be known that three factors of game addiction(tolerance, disregard of everyday life, damage of control) and two factors of covert narcissism(exploitation/self-centeredness, oversensitivity/vulnerability) showed significant explanatory power for aggression. Third, the Structural Equation Model was designed in which factors of game addiction and covert narcissism with significant explanatory power for aggression were included. Covert narcissism was found to partially mediate the influence of the boys' game addiction on aggression. Finally implications of this study and directions for future research were discussed.

This paper aims to identify the characteristics of literary therapy in relation to literature education. It also intends to clarify its distinctiveness. Literary therapy is not to teach literature. It does not deliver knowledge on agreed analyses, backgrounds and the nature of genres. Literary therapy encourages participants to fully appreciate one's thought and emotions and express them. The end goal is self-knowledge rather than the understanding of texts. Literary therapy focuses on self-knowledge through literatures as opposed to literature education which aims to encourage understandings of literature texts. In literary therapy, literature is media for personal growth facilitating self-expansion. Literature works enable participants to view oneself objectively by the means of one's responses to literature works. Literary therapy has more permissive viewpoints on recipients' response to literature texts than literature education. In addition, the subject of literary therapy is more unique and individualistic.
