영재교육에 대한 관심과 대상의 증가로 영재교육 프로그램 개발에 관한 연구가 많이 진행되고 있지만 영재들의 다양한 흥미와 요구에 부합되고 인성측면을 강조할 수 있는 지구과학 영역의 교육활동 자료 개발은 부족한 실정이다. 이에 본 연구는 중학교 과학영재 학생들을 대상으로 지구과학 분야에 대한 능동적 소집단 협력학습 프로그램을 개발하고 개발된 프로그램이 과학영재들의 과학 창의적 문제해결력과 과학탐구능력 및 학습태도에 미치는 효과를 알아보았다. 그리고 능동적 소집단 협력학습 프로그램을 적용한 후 학생들의 수업프로그램에 대한 인식을 조사하였다. 본 연구의 결과 개발된 능동적 소집단 협력학습 프로그램은 영재들의 과학 창의적 문제해결력과 학습태도에 있어서 유의미한 증가를 보였다. 또한, 능동적 소집단 협력학습은 학생들의 수업에 대한 흥미도와 만족도 및 참여도를 높일 수 있고 정의적영역에도 많은 영향을 끼치는 것으로 나타났다. 이러한 결과는 교사 설명 위주의 수업이 아니라, 학생 중심의 다양한 활동적 수업이 진행되었고 긍정적 상호작용을 위한 급우들과의 토의 및 토론을 할 수 있었기 때문이다. 이는 능동적 소집단 협력학습을 통하여 다른 학생을 배려하고 서로 조화를 이루며 의견을 주고받을 수 있도록 소집단 구성원 사이의 상호작용을 촉진했기 때문으로 인식된다.

Background: This descriptive study aimed to examine the relationship between the 4C core competencies and work ability among dental hygienists. Methods: From November 2018 to January 2019, data were collected-from 190 dental hygienists workong in dental clinics in Busan, Ulsan, and Gyeongsangnam province using structured questionnaires. For the general characteristics of the dental hygienists, frequency and percentage were calculated, and the level of the 4C core competencies and work ability of dental hygienists was calculated using means and standard deviations. A multiple regression analysis was conducted to analyze the effects of the 4C core competencies on work ability. Results: The mean scores for the 4C core competency levels of the dental hygienists were as follows: communication ability 3.34, critical thinking ability 3.41, creative problem-solving 3.40, and collaborative self-efficacy 3.27. Meanwhile the mean score for work ability level was 3.65. The predictive factors influencing work ability were communication ability and cooperative self-efficacy (p<0.001), and the sub-factors of critical thinking ability that affect work ability were sound conferences (p<0.01), intellectual fairness (p<0.05), intellectual enthusiasm (p<0.05), and self-confidence (p<0.001). Finally, the sub-factors of creative problem-solving ability that affect work ability were planning and execution (p<0.01) and performance evaluation (p<0.05). Conclusion: The current study showed that education programs covering the core competencies of dental hygienists, rather than the existing theoretical education program, should be developed and implemented to enhance 4C core competencies that affect work ability.

The future society will demand that enables one to solve in many fields by connecting various informations in many fields and then creating his own information. In the coming society, creativeness will be regarded much important. This ability can be developed with materials through group activities experimental class in math classes. This classes using these materials are not teacher-oriented, explanatory classes but student-oriented ones. They offer students opportunities to think by themselves and expand their potential abilities. They are suitable for rising and keeping student's interests. Therefore experimental classes through group activities enable students to think mathematically and make them recognize the importance of mathematical approach by letting them work connecting other subjects or things in real life. They can develop not only expressive, communicative ability and cooperative spirit, but also the ability to transcend the class itself and then reorganize facts in new insights. Besides, math classes with experiments can arouse student's curiosity familiarizing them with mathematics. Moreover, they can expand student's originative and problem-solving abilities.

In distributed autonomous robotic systems, each robot must behaves by itself according to the its states and environements, and if necessary, must cooperates with other orbots in order to carray out a given task. Therefore it is essential that each robot has both learning and evolution ability to adapt the dynamic environments. In this paper, the new learning and evolution method based on reinforement learning having delayed reward ability and distributed genectic algorithms is proposed for behavior learning and evolution of collective autonomous mobile robots. Reinforement learning having delayed reward is still useful even though when there is no immediate reward. And by distributed genetic algorithm exchanging the chromosome acquired under different environments by communication each robot can improve its behavior ability. Specially, in order to improve the perfodrmance of evolution, selective crossover using the characteristic of reinforcement learning is adopted in this paper, we verify the effectiveness of the proposed method by applying it to cooperative search problem.

In this paper, we propose a method of cooperative control (T-cell modeling) and selection of group behavior strategy (B-cell modeling) based on immune system in distributed autonomous robotic system (DARS). Immune system is living body's self-protection and self-maintenance system. These features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For applying immune system to DARS, a robot is regarded as a B-cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-cell respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control school is based on clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.

If one is looking for an organization that will be responsive to community needs, stimulate economic growth, and raise people's income, cooperatives should be an obvious choice (Calkins & Ngo, 2005; Larocque et al., 2002). This paper investigates whether the households' income is affected by the access to cooperatives for the case of Phong Dien district, Can Tho city of Vietnam. Data used are directly collected from 250 households that are both participating (120 observations) and not participating in the cooperatives in Truong Long, Tan Thoi, Nhon Ai and Nhon Nghia communes. By using the Probit model, the findings show that there are three statistically significant factors affecting the ability of farm households to participate in the cooperatives at the 1 percent level including land area, distance to market center, and education level. In addition, the PSM model analysis suggests that the average income of cooperative members is significantly higher than that of non-members, about 40.880 million VND/year at the significance level of 1 percent. The empirical results imply that being a cooperative member is a significant contributory factor toward an increase in household income. Based on the research findings, several recommendations to improve the households' income are proposed.

Purpose: This study was done to examine effects of task performance style, communication ability and their interaction on problem-solving ability and nursing competency of nursing students participating in a nursing management practicum. Methods: The study was a non-equivalent control group non-synchronized design. Participants were 56 fourth year nursing students (25 in the cooperative task group and 31 in the individual task group) and data were collected from March to September 2010. Additionally, two groups were classified based on communication ability of students and four groups were classified by their task performance style and communication ability. Problem-solving ability and nursing competency were measured pre- and post-test and compared between groups. Data were analyzed using SPSS Windows 17.0 program. Results: Neither problem-solving ability and nursing competency were statistically significantly different according to task performance style. Nursing competency was statistically significantly higher in the high communication group compared to the low communication group. Problem-solving ability was significantly different among the four groups classified by task performance style and communication ability. Conclusion: Nursing educators may need to improve students' communication ability to improve nursing competency and also assign different tasks based on communication ability of nursing students to improve problem-solving ability.
