In this study, we investigated the influences of the method of using analogy on concept understanding, mapping understanding, and mapping error by analogical reasoning ability level. We also investigated students' perception of a role-playing analogy activity. Seventh graders (N=152) at a middle school were assigned to the comparison and the experimental groups. The students of the experimental group were taught about 'the relation between pressure and volume of gas' with experience-based role-playing analogy, while those of the comparison group were taught with explanation-centered analogy. Analyses of the results revealed that the instruction using roleplaying analogy was more effective in concept understanding and retention of mapping understanding than explanation-centered analogy instruction, regardless of analogical reasoning ability level. It was also found that the students of the experimental group had fewer mapping errors than those of the comparison group. However, there was little difference in t pes of mapping errors by the method of using analogy. The students of the experimental group answered that they did not have difficulties in performing the role-playing analogy activity and they actively engaged in the activity. They perceived that the role-playing analogy activity was interesting. Educational implication of these findings are discussed.

. 최근 인구구조의 변화는 급속한 노령화로 요약되고, 이에 따라 제기되는 각종 노인문제는 각 부문별로 정책적 대응을 필요로 하고 있음. . 우리나라는 세계적으로 유래를 찾아볼 수 없을 정도의 속도로 노인인구가 급속하게 증가하는 가운데, 전통적으로 가족을 중심으로 하는 사적 영역에서 담당해오던 노인 부양기능이 약화되고 있으며, 낮은 출산율로 인해 청장년층의 노인부양 부담이 점차 더욱 커질 것으로 전망됨. - 특히 노년기의 보건학적 특성으로 인하여 보건 분야의 주요 현안들을 야기하고 있는데, 노인인구는 보건의료서비스에 대한 수요가 높은 집단으로 1인당 보건의료비용 또한 가장 높은 집단일 뿐만 아니라, 노인의 건강문제는 보건의료서비스 이외에 건강문제로 파생되는 다양한 사회적 서비스와 연계되어 있음. - ­이러한 사실은 한편으로는 우리 사회가 향후 노인의 건강문제로 인해 발생하는 높은 비용과 부담을 지게 될 것이라는 사실을 의미함과 동시에 다른 한편으로는 이에 대한 대책을 시급히 마련해야 한다는 것을 의미함.

The purpose of this study was to investigate the effect of specialized thematic science club activities on the students' scientific attitudes. The subjects of this study were ninety students from two high schools in Korea. The study group consisted of forty experimental groups and forty six science clubs with no special topics. The mean, standard deviation, t-value, and significance were compared with the corresponding sample t-test. First, specialized thematic science club activities showed positive effects on students' scientific attitude. Although the average scores of the scientific attitudes of the experiment group and the control group were improved before the operation of the club, the increase of the experimental group which operated the specialized topic was larger than that of the control group and there was a statistically significant difference. In the analysis of sub-elements of scientific attitude, the increase of the experimental group was larger than that of the control group. There were no statistically significant results in the control group, but the experimental group showed significant differences in openness, creativity, and cooperativeness among the subordinate factors of scientific attitude. Second, to investigate the effects of the specialized thematic science club activities on the scientific attitude in school, family, and social situations solving the problems of daily life as well as solving the science problems, there was no significant difference within the group, but there was a statistically significant difference between the experimental group with the specialized topic and the home and school situation. This result indicated that the scientific attitudes required to solve problems in the home and school have improved positively.

In the reality that the boundary between the real world and the virtual world disappears with the 4th Industrial Revolution, cyber crimes that occur beyond time and space have clear limitations in fulfilling their duties only with the police force of government organizations established under the real law system. The research method of this thesis is based on the literature research and the experience of security work. The purpose of this paper is to establish a social system where collective intelligence of each social field can participate voluntarily to respond to cyber crimes occurring beyond the time and space before the law and institutionalization. In addition, the social system in which collective intelligence in each social sector can participate voluntarily was established to define crime types in cyberspace in real time and to prevent crimes defined by the people themselves and the counter-measures had been proposed in order to form social consensus. First, it is necessary to establish a collective intelligent network-type cyberpolice volunteer system. The organization consists of professors of security and security related departments at universities nationwide, retired public officials from the National Intelligence Service, the National Police Agency, and the National Emergency Management Agency, security companies and the organizations, civilian investigators, security & guard, firefighting, police, transportation, intelligence, security, national security, and research experts. Second, private sector regulation should be established newly under the Security Business Act. Third, the safety guard of the collective intelligent cyberpolice volunteer system for the stability of the people's lives should strengthen volunteer work. Fourth, research lessons and legal countermeasures against cybercrime in advanced countries should be introduced. Fifth, the Act on the Protection of Personal Information, the Act on Promotion of Information and Communication Network Utilization and Information Protection, the Act on the Utilization and Protection of Credit Information, and the Special Act on the Materials and Parts Industry should be amended. Sixth, police officers should develop cybercrime awareness skills for proactive prevention activities.

This study examined the effects of song-based group music therapy on the exercise stress and positive psychological capital of youth soccer players. Eighty youth soccer players were assigned to either a song-based music therapy group or a control group. For the analysis of the effects of song-based group music therapy, the Exercise Stress scale and the Athlete Positive Psychological Capital scale were administered before and after the intervention. The collected data were analyzed using an independent sample t test and paired t test. The results were as follows. First, the experimental group showed a significantly lower posttest score on the exercise stress measure than the control group (p < .01). The control group showed a significant increase from pretest to posttest on the exercise stress measure (p < .05). Second, the experimental group scored significantly higher at posttest than the control group on the positive psychological capital measure (p < .01). The control group demonstrated a statistically significant decrease from pretest to posttest on the positive psychological capital scale (p < .05). The results suggest that song-based group music therapy is an effective treatment method that lowers exercise stress and raises positive psychological capital of youth soccer players.

This paper is an anthropological study on the regional revitalization movement by the traditional ceramic industry in Mashiko-cho, Japan. It especially deals with the issues like history of revitalization based on ceramics, idealogical features and roles of core activist group, and adaptive strategies of local society to the ever-changing circumstances. The ceramic industry of Mashiko-cho had developed vigorously in 19C, and had passed many critical points in 20C. In 1960s, the ceramic industry of Mashiko-cho developed stably through introducing of Mingei(民藝) ideology and artists. This is evaluated as a 'bottom-up' regional revitalization movement and a active utilization of traditional cultural resources. In Mashiko-cho, the ideological leadership of cultural artist groups have been central roles in the regional revitalization movement. The representative cases are transformation of production of ordinary ceramics to production of Mingei ceramics from the middle of 1950s, official organization of core activist group and establishment of direct sale system by the producers in the middle of 1960s, and full-scale cooperation of private sector and public sector from the beginning of 1980s. Nonetheless the regional revitalization movement by the traditional ceramic industry in Mashikocho have come out well up to now, it should make new tradition which is well-matched to the ever-changing circumstances as seeing various and complex differentiation on the inside of local society.

In this study, the educational effect were sought to be identified after developing and applying project learning for the artificial intelligence based liberal arts education for the non-computer majors. A paired-sample t-test was performed within each group to determine the extent of improvement in the learning flow and artificial intelligence efficacy in the experimental and control groups. After class, an independent sample t-test was performed to examine the statistical effects of pre-test and post-test on the learning flow and artificial intelligence efficacy in the experimental and control groups. The experimental group and control group demonstrated significant improvements in the learning flow and artificial intelligence efficacy before and after class, each respectively. There was no statistically significant difference in the learning flow between the experimental group for which the project learning method was applied and the control group for which only theory and practice were conducted in the artificial intelligence class. It was also confirmed that the experimental group for which the project learning method was applied improved the efficacy of artificial intelligence to a significant level compared to the control group which only proceeded with theory and practice.

Top-down approach in the intelligent robot research has focused on the single object intelligence however, it has two weaknesses. One is that has a high cost and a long spending time of sensing, calculating and communications. The other is the difficulty of responding to react changes in the unpredictable environment. we propose the collective intelligence algorithm based on Bottom-up approach for improving these weaknesses and the applied agent model and verify by simulation. The Modified Flocking Algorithm proposed in this research is the algorithm which is modified version of the concept of the Flocking (Craig Reynolds) which is used to model the flocks, herds, and schools in the graphics or games, and simplified the operation of conventional Flocking algorithm to make it easy to apply for the number of group robots. We modeled the Boid agent and verified possibility collectivization of the Modified Flocking Algorithm by simulation. And We validated by the actual multiple mobile robot experiment.

급변하는 환경에 대응하기 위하여 최근 우리나라의 기업들은 책임경영제, 팀제, 수평 조직, 권한이양, Client/Server환경 등 다양한 기법들을 도입하고 있는데, 이들 기법들의 공통적인 특징을 한 마디로 표현하면 분권화라 할 수 있을 것이다. 따라서 분권화가 지닌 전체 최적인 아닌 부분 최적, 구성원간의 갈등, 조직 전체적 차원의 의사결정 및 실행의 어려움등과 같은 기본적인 문제들을 해결하기 위해서 이해관계자들간의 집단의사결정의 중요성은 분권화의 추세와 더불어 더욱 증대되고 있다. 본 연구는 S그룹의 산임과장 700여명을 6-7명을 한 조로 하여 총 110개 조를 편성한 후, 조별로 문제를 해결해 가는 과정을 직접 관찰하였다. 관찰결과 110조 중 100조 이상이 거의 동일한 의사결정 과정을 밟아갔으며 그들이 밟아 간 과정은 합리적 의사결정이론에서 제시하는 과정과는 거리가 멀었다.
