Existing tools using in the standard e-learning contents authoring were used a method to provide users contents template produced in advance. In order to use resources of the template in a common web-based authoring tool, there is problem to overcome. If the resource of template is inserted within the contents on the authoring tool, the deformation of the template by the user's input that may occur during the edit process cannot be controlled. In this paper, we propose an effective maintenance method to prevent deformation of the resource of template inserted into any WYSIWYG-based HTML authoring tool by user's discretion. We added a template plug-in that can create the IMS-QTI standard resource in tynyMCE the web-based open source editor of representative examples. And the plug-in for tinyMCE was realized as a module of directly respond to the action of limited user input. So, in response to the action of user's input, the structure of the template can be sustained possibly.

Using a nationally representative sample from three recent waves of the Korean Welfare Panel Study, this study examined the association between experiencing material hardship and suicidal ideation among low-income households in South Korea. Overall, we found that experiencing material hardship was associated with a higher likelihood of having suicidal ideation. We also found that, among individual items of material hardship, experiencing food insecurity or credit problems was associated with a higher likelihood of having suicidal ideation. Furthermore, we found that the association of experiencing material hardship with having suicidal ideation was more pronounced for male-headed or elderly-headed households. Policy implications to improve living condition among low-income households and reduce their suicide-related behavior were discussed.

Objectives: This study was conducted to describe child perceived health knowledge, health education needs, and health behaviors by sex as a representative general characteristic and examined their associations for students' better health behavior changes. Methods: The survey participants were 410 fourth to sixth grade students in two elementary schools in Seoul, Korea. A total of 12 classes in two elementary schools were randomly selected and all students of the selected classes participated in the self-administered survey. The questionnaire contained the items of perceived health knowledge, health education needs (health topics which they want to know more), health behavior, and general characteristics. Results: Perceived health knowledge, health education needs, and health behaviors were, generally, better among girls than boys. Sexual differences were not large in perceived health knowledge, health education needs, health behaviors. Perceived health knowledge had significant positive correlation with health behaviors both in boys and girls(p <.01). The correlation between perceived health knowledge and health behaviors(r =.36) was two fold greater than correlation between health education needs and health behaviors(r =.18) among boys; where as the two correlations were similar to each other among girls. The significant factors were perceived health knowledge, sex, grade, and health education needs in order, and the four factors described health behaviors in 21.0%. The higher perceived health knowledge, girls, lower grade, and more health education needs was associated with the better health behaviors. Conclusions: There was significant sexual difference of the relationship between health knowledge, health education needs, and health behaviors among children. Perceived health knowledge was more important factor to improve health behaviors among boys while perceived health knowledge and health education needs had equal importance on health behaviors among girls. Therefore, knowledge building should be an essential part of health education class goals for building better health behaviors.

As big data technologies have been developed and massive data have exploded from users through various channels, CEO of global IT enterprise mentioned core importance of data in next generation business. Therefore various machine learning technologies have been necessary to apply data driven services but especially recommendation has been core technique in viewpoint of directly providing summarized information or exact choice of items to users in information flooding environment. Recently evolved recommendation techniques have been proposed by many researchers and most of service companies with big data tried to apply refined recommendation method on their online business. For example, Amazon used item to item collaborative filtering method on its sales distribution platform. In this paper, we develop a commercial web service for suggesting music contents and implement three representative collaborative filtering methods on the service. We also produce recommendation lists with three methods based on real world sample data and evaluate the usefulness of them by comparison among the produced result. This study is meaningful in terms of suggesting the right direction and practicality when companies and developers want to develop web services by applying big data based recommendation techniques in practical environment.

Nowadays the preschool children spend much of the day playing indoors. Therefore, it needs the indoor environment that helps a variety of fun activities and physical development, and it requires the space configuration and playable furniture considering the emotional development for mental health. However, the furniture for fast growing preschoolers has not various types because the domestic furniture market for children is mostly baby beds and the furniture for the education of children. Therefore, this study presents the concepts and types of the playable furniture reflecting emotional design for preschool children's healthy emotion and suggests the most appropriate type of playable furniture considering play behavior by age. In this study, we investigated the physical, cognitive, social, emotional and linguistic development characteristics and play behavior of preschoolers, and derived the right type of playground equipment and furniture, and examined the types of playable furniture to help the emotional development. We derived the items to be checked for developing the playable furniture by age for emotional development, and classified preschoolers' playable furniture into the use of learning, relaxation and storage, and suggested its basic type focusing on the cases of various playable furniture developed at home and abroad. As a result, the playable furniture was divided into three types. The first is the self-play type making possible self amusement, the second is module built-up-type that consists of furniture and modules or units and creates various patterns and can be modified through the self-assembly and disassembly, and the third is IT game type grafting IT skills and a variety of electronic games to furniture. We sorted these types into three classes (1-3 years old, 4-5, 6-7) according to age and presented the type of play for each age, the play element and representative image that can be introduced to this furniture. In this study, we provided the basic design types of age-specific emotional playable furniture by analyzing these results.

The application of advanced Main Control Room(MCR) is accompanied with lots of changes and different forms and features through the virtue of new digital technologies. The characteristics of these digital technologies and devices give many opportunities to the interface management, and can be integrated into a compact single workstation in advanced MCR so that workers can operate the plant with minimum physical burden under any operation conditions. However, these devices may introduce new types of human errors and thus a means to evaluate and prevent such errors is needed, especially those related to characteristics of digital devices. This paper reviewed the new type of human error hazards of tasks based on digital devices and surveyed researches on physiological assessment related to human error. An experiment was performed to verify human error hazards by physiological responses such as EEG which was measured to evaluate the cognitive workload of operators. And also, the performances of four tasks which are representative in human error hazard tasks based on digital devices were compared. Response time, ${\beta}$ power spectrum rate of each task by EEG, and mental workload by NASA-TLX were evaluated. In the results of the experiment, the rate of the ${\beta}$ power was increased in the task 1 and task 4 which are searching and navigating task and memory task of hierarchical information, respectively. In case of the mental workload, in most of evaluation items, task 1 and 4 were highly rated comparatively. In this paper, human error hazards might be identified by highly cognitive workload. Conclusively, it was concluded that the predictive method which is utilized in this paper and an experimental verification can be used to ensure the safety when applying the digital devices in Nuclear Power Plants (NPPs).
