Since the start of gifted education in 2002, educational support system has now been established, and sufficient growth in quantitative aspects has been achieved in Korea. On the other hand, they report that there are insufficient points in terms of education quality. In other words, most of the gifted education simply expands knowledge by prior-learning. In order to improve the quality of gifted education, they should enhance critical-thinking and creativity able to apply interdisciplinary principles or phenomena for solving problems. In this study, we designed and developed a convergent teaching-learning materials based on the concept of integrated education, which explore the process that basic logic operations such as AND, OR, XOR do the role of computer cells. A survey result showed that student satisfaction(usefulness, understanding, interest) of the materials is significantly higher than that of other traditional learning topics, and the design intent was met.

At most of the home or office, we have planted ornamental plants raised in pots, but it is difficult to follow because of busy life and lack of expertise in plants management. In this paper, we intend to design and implement a home network-based potted plants management system to solve the difficulty of plants management. To attain this end, firstly, we designed the structure of the plants management system, information flows and operation control flows. Secondly, we implemented the system based on designed results. Finally, we verified the implemented system through the functionality test for 10 items. In the results, it is expected that we can manage the potted plants efficiently than existing ornamental plant management systems and home network systems focusing appliances.

This study evaluates the flow of Taoism in the change of knowledge that accompany the passage of time beyond school-centered studies. In particular, it is to understand the Tao(道) and T'ien(天) of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" in the thought of T'ien at the time. The thought of T'ien at that time was based on the T'ien in "Mencius". There are two meanings of T'ien in "Mencius", and also of T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$". This study examins that idea that the T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were influenced by the thought of T'ien in "Mencius". It also reveals the T'ien theory of Wang Ch'ung(王充) which is influenced by Taoism. Also, in the course of examining the relation of T'ien theory of Wang Ch'ung with T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$", it is more embodied that T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were affected by the previous T'ien theories. Furthermore, the meanings of Tao in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" are revealed.

Da-san Jeong Yak-yong(정약용) was one of the notable realist in the late 18th century, the second half of Chosun Dynasty. He accentuate the need of national riches and stabilization of the public welfare through his reformat proposal on actual condition. He regarded geography as the necessary knowledge to achieve the national riches and stabilization of the people's livelihood. We can read the contents on agricultural policy and encouragement of farming in Mokminsimseo(목민심서). In Mokminsimseo(목민심서), as coverage on economic geography, he present various policy of encouragement of agriculture as device of agricultural promotion and urges governors initiative on this. On policy of encouragement of agriculture, he insisted that the farmers have side job like horticulture, sericulture and live-stock farming far their rural economy. In sum, Da-san Jeong Yak-yong regarded economic geography as a important subject under realism which aims at improving and reforming contemporary world against 주자학 oriented Confucian classics.

There is insufficient effective management systems to achieve project goalsin disaster and safety R&D. Therefore, to develop an R&D performance management system, this paper develops a R&D performance management matrix based on PMBOK to systematize a process and to enhance efficiency of performance management. Also, this paper identified vulnerable procedures in disaster management by analyzing related laws, work process and performance. Analysis results found that the performance management matrix in disaster management R&D consists of 5 process groups, 7 knowledge areas and 47 processes. Also, the performance of the diffusion knowledge process was evaluated as weak in the present management system. This study defined ITO and developed a data flow diagram for applicationto related work. The suggestions of this study include the related work to enhance R&D performance, contribute to improving diffusion of R&D performance, and enhance the utilization of developed technologies.

This study was conducted to identify the effects of baby care using dolls on nursing students' major satisfaction, class satisfaction, and knowledge of newborn care. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 95 nursing college students who agreed to participate. The control group (n=47) received lecture education consisting of watching newborn videos while the experimental group (n=48) received a practical education involving caring for a doll resembling an infant. Data were collected from March to May, 2019 and analyzed using descriptive statistics, χ²-tests, and t-tests with the SPSS/WIN 21.0 program. The major satisfaction score of the experimental group was higher than that of the control group, but it was not statistically significant (t=1.64, p=.107). The score for class satisfaction differed significantly between the experimental group and control group (t=2.08, p=.043). The knowledge of newborn care score for the experimental group was higher than that for the control group, and there was a statistically significant difference (t=-5.82, p<.001). Overall, the results show that baby care using a doll has positive effects on class satisfaction and knowledge of newborn care. In the future, it will be necessary to develop and apply effective teaching methods in line with the times.

Rapid development of information and communication technologies leads firms to take 'smart work' into serious consideration as a new way of working in coming knowledge and information society. However, some jobs may be fit for smart work while some may be not. A $2{\times}2$ framework for smart work readiness assessment is developed in this study through the review of extant literature and a series of focus group activities. Two critical dimensions of smart work are derived and presented as a result: smartness (knowledge versus data) and mobility (mobile versus static). Knowledge intensive jobs with possible mobility seem to be the target group that can be easily converted to smart work while mobile workers with interactive data processing devices seem to be already doing smart work. As mobility is a critical presumption for work to be flexible in terms of time and place, jobs with no mobility are assessed here as not ready for smart work at least at present. This framework is experimentally applied against the published job statistics 2011 in Korea, and used to estimate the number of workers ready for smart work. As a conclusion, discussions on policy implications and further research issues are made at the end.
