Computer Assisted Learning (CAL) is quite different from in many aspects. CAL provides individualistic learning environment and facilitates autonomy of the learner. Thus the learners who uses CAL program has more sense of control and engages in more strategic learning than conventional learning environment. In this experiment, we used KORI (KORea university intelligent agent) which is a new type of ITS adopting TA (Teachable Agent) that fosters learning by teaching, So, we investigated the critical motivational factor that have influences in CAL learning and the effects of reward in CAL are another area of our interest. Thus, we divided two conditions that presence of reward and absence of reward. The 174 elementary school students(5th) were participated and they are randomly assigned the one of the reward conditions. Before entering the experimental instruction, all participants measured about metacognition, self-efficacy and goal orientation questionnaire as independent variables. Then, Participants were instructed of method of using KORI program and asked to study for ten days with KORI program at least 20 minutes everyday in their home, about 10 days. After 10 days, they were rated interest and comprehension. Regression results suggest that regardless of the presence of reward, metacognition is a positive predictor in interestingness. It indicate that metacognitive skills are required in CAL learning situation irrespective of reward. But on comprehension in the absence of reward, only self- efficacy appeared to be a positive predictor. In the presence of reward, performance goal orientation showed as a negative predictor of comprehension, whereas self-efficacy was a positive predictor. This result suggest that presence of reward especially interferes learning process of performance goal orientation in CAL learning situation. It could be interpreted that reward interferes the learning process of performance goal orientation by debilitating intrinsic motivation.

Purpose: The purpose of this study is to investigate relationships among sun-screening agents use, bone health promotion behavior, and bone mineral density. Methods: The participants of this study were 105 female college students. The data were collected using a questionnaire about sun-screening agent use and bone health promotion behavior. Bone mineral density was measured with Ultrasound Bone Densitometer/Osteo Pro Series. Data were analyzed with the SPSS/Win 18.0 program. Results: The mean Z-score in female college students was $-1.04{\pm}1.26$, and the T-score was $-1.16{\pm}1.22$, 21.39% of the participants have osteopenia. Bone mineral density showed a significant correlation with weight. Bone mineral density showed no significant correlation between sun-screening agent use, and bone health promotion behavior. There was a significant correlation between protection power of sun-screening agents and the protection by clothes. Conclusion: According to the results of this study, we need to develop an intervention program for bone health promotion of female college students.

This study examines the recognition of the user's sound command based on speech recognition and natural language processing, and develops the natural language interface agent which can analyze the recognized command. The natural language interface agent consists of speech recognizer and semantic interpreter. Speech recognizer understands speech command and transforms the command into character strings. Semantic interpreter analyzes the character strings and creates the commands and questions to be transferred into the application program. We also consider the problems, related to the speech recognizer and the semantic interpreter, such as the ambiguity of natural language and the ambiguity and the errors from speech recognizer. This kind of natural language interface agent can be applied to the telephony environment involving all kind of communication media such as telephone, fax, e-mail, and so on.

Centella asiatica is an herbal plant used on different continents by diverse ancient cultures and tribal groups. Historically. the extract has been used as a wound healing agent, The extract has three different triterpenoid ingredients: asiaticoside. asiatic acid, and madecassic acid. It has been reported that its wound healing activity is associated with the modulation of collagen synthesis in the skin dermis. The wound healing property of the extract has led to its commercial introduction under the trade name, Madecrlssol. As part of our program toward the development of new wound healing agents. structere activity relationship (SAR) studies have been performed by modifying asiatic acid. In this communication. the SAR study of esiatic acid for the development of an efficient woind healing agent is reported.

이동 에이전트는 네트워크로 연결된 컴퓨터들을 사용자를 대신하여 작업을 수행하며 이동위치를 스스로 결정할 수 있는 자율성(autonomy)과 이동성(mobility)을 가진 소프트웨어 프로그램이다. 이동 에이전트는 네트워크 연결을 계속 유지한 상태로 작업하지 않고 실행 코드와 상태가 시스템간을 이동하며 임무를 수행할 수 있기 때문에 네트워크 연결이 불안정한 무선 망 환경이나 부하가 많이 걸리는 환경에서 활용될 수 있다. 본 논문에서는 이동 에이전트 패러다임을 사용함으로써 이동 컴퓨팅 환경에서 상품 검색 및 매매를 효율적으로 수행할 수 있는 전자상거래 시스템을 구축할 수 있음을 보여주고 있다. 사용자를 대신하여 복수 개의 이동 에이전트들이 시장으로 직접 이동하여 서비스나 상품을 자율적으로 협상하거나 매매하고, 매매결과는 에이전트 실행 코드와 함께 출발지 시스템으로 이동하여 보고한다. 따라서, 우리는 이동 마켓 시스템을 설계하고 시범 구현함으로써 이동 에이전트 패러다임이 이동 컴퓨팅 환경에서 전자상거래 시스템 구축에 적합함을 보인다.

특허 침해소송은 다른 소송들과는 다르게 그 특허기술의 실체파악 없이는 사안의 파악이 매우 힘든 소송이다. 변리사법은 제8조에서 변리사의 특허침해소송에 대한 소송대리권을 인정하고 있는 듯 보이지만 전통적으로 헌법재판소와 법원은 특허 등 침해소송에 대하여 변리사의 소송대리권을 인정하지 않는 입장이다. 이에 대해서 변리사와 변호사간에 끊임없는 논쟁이 이루어지고 있다. 본 연구에서는 특허침해소송에서 소송대리의 효율성 및 전문성을 높이는 방안을 탐색한다. 이를 위해 주요국의 특허침해소송에서 변리사의 역할을 분석하여 합리적 대안을 도출한다. 그 결과 변호사의 변리사 자격 자동취득을 제한하거나 변리사의 소송대리권과 관련하여 변리사법을 개정하는 방안은 적절하지 못한 것으로 나타났다. 소송당사자의 입장에서 근본적인 문제 해결을 위해 수정된 특허전문변호사 제도를 도입하고 소송당사자들이 합리적으로 소송대리인을 선택하게 하는 것이 바람직한 대안인 것으로 분석되었다.

The researchers in the field of cognitive science and learning science suggest that the teaching activity induces the elaborative and meaningful learning. Actually, lots of research findings have shown the beneficial effect of learning by teaching such as peer tutoring. But peer tutoring has some limitations in the practical learning context. To overcome some limitations, the new concept of "learning by teaching" through the agent called Teachable Agent. The teachable agent is a modified version of traditional intelligent tutoring system that assigns a role of tutor to teach the agent. The teachable agent monitors individual difference and provides a student with a chance for deep learning and motivation to learn by allowing them to play an active role in the process of learning. That is, The teaching activity induces the elaborative and meaningful learning. This study compared the effects of our teachable agent, KORI, and peer tutoring on the cognition and motivation. The field experiment was conducted to examine whether learning by teaching the teachable agent would be more effective than peer tutoring and reading condition. In the experiment, all participants took 30 minutes lesson on rock and rock cycle together to acquire the base knowledge in the domain. After the lesson, participants were randomly assigned to one of the three experimental conditions; reading condition, peer tutoring condition, and teachable agent condition. Next, participants of each condition moved into separated place and performed their own learning activity. After finishing all of the learning activities in each condition, all participants were instructed to rate the interestingness using a 5-point scale on their own learning activity and leaning material, and were given the comprehension test. The results indicated that the teachable agent condition and the peer tutoring condition showed more interests in the learning than the reading condition. It is suggested that teachable agent has more advantages in overcoming the several practical limitations of peer tutoring such as restrictions in time and place, tutor's cognitive burden, unnecessary interaction during peer tutoring. The applicability and prospects of the teachable agent as an efficient substitute for peer tutoring and traditional intelligent tutoring system were also discussed.

In this study, we investigated the effect of natural vegetable treatment agent on the bleaching and damage of human hair during permanent wave formation. The vegetable treatment agent was prepared by fermenting the mixture of tea leaves (10g), black rice (100g), black bean (100g), corn (100g), malt (50g), and water(500g) at room temperature for 1 week. The degree of bleaching and damage was checked by Munsell value 'L' and morphological changes of hair in FE-SEM. When the hair was bleached, the Munsell value 'L' was almost same regardless of adding the vegetable treatment to the bleaching solution. But when the hair was permanently waved, the curl formation ability was high and the damage was low in the case of adding the vegetable treatment. This means that the vegetable treatment covers the scale of hair and protects the hair from the chemicals.
