  • We propose the VS3-NET model to solve the task of question answering questions with machine-reading comprehension that searches for an appropriate answer in a given context. VS3-NET is a model that trains latent variables for each question using variational inferences based on a model of a simple recurrent unit-based sentences and self-matching networks. The types of questions vary, and the answers depend on the type of question. To perform efficient inference and learning, we introduce neural question-type models to approximate the prior and posterior distributions of the latent variables, and we use these approximated distributions to optimize a reparameterized variational lower bound. The context given in machine-reading comprehension usually comprises several sentences, leading to performance degradation caused by context length. Therefore, we model a hierarchical structure using sentence encoding, in which as the context becomes longer, the performance degrades. Experimental results show that the proposed VS3-NET model has an exact-match score of 76.8% and an F1 score of 84.5% on the SQuAD test set.

  • In this study, we investigated and compared the types of analogy generation processes and the perceptions of analogy generation on saturated solution of fifth grade scientifically-gifted and general elementary students. After the instruction of self-generating analogies on 'saturated solution' concept for two classes, 12 scientifically-gifted and 8 general elementary students were interviewed to explore their analogy generation processes and the perceptions of the abilities required in the processes, the conditions of good analogies, and the advantages/disadvantages of analogy generation. The results revealed that their analogy generation processes were classified into three types. The scientifically-gifted students generated the analogies in more systematic and efficient ways and had better understanding of the important parts in the processes than the general elementary students. They also suggested more concrete and various ideas about the conditions of good analogies. Many scientifically-gifted and general elementary students thought that analogy generation would have positive influences on the developments of the cognitive aspects such as various higher-level thinking abilities and understanding of science concepts as well as the affective aspects such as science learning motivation and interest. Educational implications of these findings are discussed.

  • The scholastic consumer education program in Japan was adopted after world war Ⅱ. And so far, based on home economics class at school, the program has undergone seven times modification with “A course of study(learning coaching guide). Now the main objective with the consumer education program, initiated from ‘purchasing skill’ and ‘information offer’, has been shifted to the direction of stressing the ‘reasonable decision making’ and ‘invocation of consumer recognition’. The concrete operation of the scholastic consumer education program in Japan was managed and operated to the direction of urging the student to think independently and self-motivated and provoking the power of thinking, while utilizing daily works closely to routine life as educational materials and subjects. The investigations on Japanese scholastic consumer education program which have been developing and accumulating concrete instances and know-how's of scholastic consumer education program are considered to be still suggestive, and we may conclude it's necessary for both of Korea and Japan to interchange necessary experiences and ideas on this field with each other.

  • In general, Evoluationary Algorithm(EAs) are refered to as methods of population-based optimization. And EAs are considered as very efficient methods of optimal sytem design because they can provice much opportunity for obtaining the global optimal solution. This paper presents a co-evolution scheme of artifical neural networks, which has two different, still cooperatively working, populations, called as a host popuation and a parasite population, respectively. Using the conventional generatic algorithm the host population is evolved in the given environment, and the parastie population composed of schemata is evolved to find useful schema for the host population. the structure of artificial neural network is a diagonal recurrent neural netork which has self-feedback loops only in its hidden nodes. To find optimal neural networks we should take into account the structure of the neural network as well as the adaptive parameters, weight of neurons. So we use the genetic algorithm that searches the structure of the neural network by the co-evolution mechanism, and for the weights learning we adopted the evolutionary stategies. As a results of co-evolution we will find the optimal structure of the neural network in a short time with a small population. The validity and effectiveness of the proposed method are inspected by applying it to the stabilization and position control of the invered-pendulum system. And we will show that the result of co-evolution is better than that of the conventioal genetic algorithm.

  • Computer programming education helps students understand abstract concepts better and solve given problems independently. Many previous studies on programming education have focused on procedural programming languages such as BASIC and C, but studies on objected-oriented program ming language like JAVA is rare. This paper examines how an architectural neural, objected-oriented JAVA programming study system can improve logical thinking ability and encourage self-led study and stimulate interests in computers among elementary school students. The system has been developed and is suitable for distributed Internet environment. The experiment results demonstrated that the objected-oriented programming education enhances logical thinking ability, exerts a positive impact on student achievement in math and science, and stimulate interests in computers.

  • Purpose: The purpose of this study is to develop the curriculum model for occupational health nurse specialist in Korea. Method: Internet searching was conducted to analyze the type of master program for occupational health nurses in the U. S. To identify the importance of occupational health nurse specialist (OHNS)'s role, self-administrative questionnaire survey was done to335 occupational health nurses through postal mail and continuing education in 2003. SPSSWIN 10.0 was used for data analysis. Results: In the U. S., two main types of nurse practitioner program and nurse manager program are separately operated for occupational health nurses as master level. Under the governmental support, geographical and financial barrier can be decreased through the distance learning and the appointment of regional ERC. Most occupational health nurses recognized importantly the role of OHNS as direct care provider, educator, consultant, and manager. Conclusion: It is recommended that the job standard for OHNS needs to be developed, and regulation has to be changed for the diverse curriculum based on the need of occupational health nurses, and governmental support must be strengthened for occupational health nurses to apply more easily to the program.

  • Purpose: The purpose of this study was to analyze intervention studies related to Snoezelen (multisensory environment). Methods: Studies related to Snoezelen (multisensory environment) published between 1995 and 2010 in both Korean and International journals were systematically reviewed, and analyzed following guidelines. Based on inclusion criteria, 23 studies including 5 Korean and 18 International articles were selected. Results: Most studies were conducted in various area of research such as medicine, nursing, and occupational therapy. There was no publication related to Snoezelen (multisensory environment) in Korean nursing journals. In terms of target population, more than 65 % of the study subjects were patients with dementia, mental retardation, and learning disability. Intervention was implemented mostly in less than 30 minutes, once a week for 2 to 4 weeks. The effects on behavior, physical, and psychological contexts were assessed as outcome indicators. There was more 'positive' than 'no effect' in self-stimulatory behaviors, problem behaviors, heart rate, pain, mood state, and anxiety, whereas more 'no effect' than 'positive' in blood pressure, respiration, enjoyment, and relaxation. Conclusion: Future studies are needed to develop the protocol and outcome indicators for effective use of this new intervention in Korea.

  • Purpose: One of the main reasons why mothers quit breast feeding is that the volume of breast milk is inadequate due to insufficiency in suckling. We believe suckling experience may be a factor affecting nipple confusion. So an alternative feeding method, namely cup, spoon, finger, or nasogastric tube feeding may be needed to prevent nipple confusion. The purpose of this study was to construct a predictive model for demand for alternative feeding education by nurses. Methods: A descriptive design with structured self-report questionnaires was used for this study. Data from 175 nurses working in hospitals in Busan were collected between April 1 and 15, 2009. Data were analyzed by decision tree method, one of the data mining techniques using SAS 9.1 and Enterprise Miner 4.3 program. Results: Of the nurses, 81.1% demanded alternative feeding education and 5 factors showed that most of them expressed intention to pay, desire to know about alternative feeding, age, and learning experience. From these results, the derived model is considered appropriative for explaining and predicting demand for alternative feeding education. Conclusion: This confirms that knowledge and compliance in alternative breast feeding for newborn babies should be correct and any inaccuracies or insufficient information should be supplemented.
