The reliability concept of wireless sensor network is essential to get exactly actual data from the ubiquitous environment. A rollback technique for the self-healing helps to increase it. However, a fault can occur in wireless sensor network when to use a previous rollback technique because it is designed just for the local system. So, checkpoint protocols are suggested in order to use a rollback technique in the network without the fault. However, there is trade-off among performance overhead, power consumption, and memory overhead for each of protocols. Hence, we suggest a novel global checkpoint protocol, so called address log based protocol(ALBP), based on an asynchronous protocol. It is a platform based protocol to reduce power consumption, performance overhead, and memory overhead which are the most of consideration in wireless sensor network.

The parents of cerebral palsy children are identified as special individual with responsibilities and roles beyond those of other parents. Physical therapist often direct their attention to the cerebrel palsy child without supporting. teaching or appreciating the parent. As parents are the most influential factor in the child's development and because parents generally have a need to be incorporated in their child's treatment and education. education regarding treatment is essential for the parent. Parents tend to seek information about their child's disability and desire accurate. Straight foreward and complete information about their child. Parent groups are advantageous organizations in that they provide mutual support and emotional and social outlets. While learning to accept a disabled child. parents must deal with additional stressful events which occur when community involvement with the cerebral palsy child begins. The parents are immediately thrust into new roles as they come into contact with medical specialists, physical therapist or other parents of disabled children. These events contribute to a psychological stress. sense of loss and lowing of selfesteem.

In recent years, personal videos have seen a tremendous growth due to the substantial increase in the use of smart devices and networking services in which users create and share video content easily without many restrictions. However, taking both into account would significantly improve event detection performance because videos generally have multiple modalities and the frame data in video varies at different time points. This paper proposes an event detection method. In this method, high-level features are first extracted from multiple modalities in the videos, and the features are rearranged according to time sequence. Then the association of the modalities is learned by means of DNN to produce a personal video event detector. In our proposed method, audio and image data are first synchronized and then extracted. Then, the result is input into GoogLeNet as well as Multi-Layer Perceptron (MLP) to extract high-level features. The results are then re-arranged in time sequence, and every video is processed to extract one feature each for training by means of DNN.

This paper applies a income mobility method to technology inequality using conditional human capital stock and shows their empirical results during the 1980 to 2000. There are several interesting empirical results coming out this analysis. Among the results, the paper turns out that world technology inequality mobility measurement is significantly higher for rapid formation of human capital stock countries than for slow formation of human capital stock countries. This paper, therefore, suggests that technology policy need to focus on improving the public education structure to recover the rate of return to human capital investment and to speed up technology development and deployment in Korea.

Data redundancy is problematic in that it not only induces heavy storage management cost but also could bring critical degradation of information systems. Unfortunately, to our knowledge, only few enterprises willingly afford time and efforts for the faithful conceptual design to prevent the degree of inappropriate data as much as they could, while most of enterprises pay rare attention to the notion of that sort of data quality. Wondering if there would be any other way to design the enterprise.wide data design without prior knowledge about business works is our major motivation for this study. In this paper, we present our data modeling methodology in which associations among objects in each sentences of a business job descriptions are treated as the focal point in database design. A proposed agent for automated design tool simply takes a business job description written in natural language as an input, and then designs an entity relationship diagram with some smart rules. We introduce the scope of the proposed agent and its detailed logics with several examples. And then, we verify the appropriateness of the resulted associations among objects. Lastly, we perform case studies to evaluate the devised agent's applicability to a business field.

Despite the fact that navigation technology and educational programs were developed and maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. In order to reduce traffic accidents at sea, the preventive index for maritime accidents is designed and measured to evaluate and visualize the activities performed. The survey module is composed of preventive domains such as education, engineering, enforcement and information. The index was abstracted from the statistics of maritime accidents causes(2010~2012). It can be evaluated by using the newly developed survey modules. It was found that there is some correlation between the index value and the accident rate of maritime traffic. It is expected that this index will become another useful tool to help prevent maritime accidents.

This paper is to explore the effects of Robot Based Instruction(RBI) on improving immersion learning. According to our research, we found out that there is significant improvement in learning immersion and there's 9 sub-factors score after RBI was applied. Also from the result that there is no significant difference between male and female students in learning immersion score, we can found that RBI can improve the learning immersion of students regardless of the learner's sex. The result of verification on the learning immersion is difference by subjects showed that there is significant improvement only in korean, science, art subject among 7 subjects. The above-mentioned results are based on as follows two reasons. First, RBI is efficient to improve students' internal motivation and ownership about tasks, and that is related to environment of learning and instruction focused on authentic task and practice. Second, educational advantages of robot media was reflected appropriately in RBI, also appropriate instructional environment for RBI was supported.
