Objective : This study aims to figure out the effect that sensory integration group therapy has on the fine motor, social interaction and playfulness of preschool children with intellectual disability. Methods : Participants were four children from three to five years old who were diagnosed with intellectual disabilities and they participated in twelve sessions of sensory integration group therapy, sixty minutes per session and once a week. Sensory integration group therapy was composed of parallel and peer play-centered gross motor activities, art activities and sensory plays that were related to each theme. Erhardt Developmental Prehension Assessment (EDPA), Penn Interactive Peer Play Scale (PIPPS) and Test of Playfulness (ToP) were used to evaluate participants' fine motor, social interaction and playfulness before and after the intervention. Results of fine motor, social interaction and playfulness before and after the intervention were compared using Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy intervention, the fine motor skills of participants did not show significant increases, but social interaction and playfulness showed significant increases (p< .05). Conclusion : Although sensory integration group therapy with preschool children with intellectual disability did not show positive improvement in fine motor skills, it showed positive effect on social interaction and playfulness. Group sensory integration therapy might be an intervention approach for all children with disabilities.

About 93$\%$ of domestic teal estate construction firms registered as the end of 2001 recorded net profits of only less than 500 million won(including firms in the red) for the term. As a result of having analyzed the ratios of sales costs and the structural ratios of sales costs for the past 10 years, it was found that there have been great changes in structural ratios of sales costs. Material costs and labor costs have gradually decreased, but outsourcing costs of processing have greatly increased. In order to find activity points which are fundamental to cost control, the methods of new activity based cost management have been pursued. The characteristics of real estate construction industry lie in the fact that contract prices (sales in) are fixed and amounts of profits differ depending on the use of costs. In order to create maximum profits from fixed contract prices, the new activity based cost management has been proposed. The control of operation budgets and management costs is designed to control their schedules and expenses in different respects. Operation budgets ate executed with specific activities and management costs are controlled as a form of material costs, labor costs, out sourcing costs and expenses which are details of expenditure. In order to execute them by using the methods of new activity based cost management, first of all, we have to analyze what activity drivers ale and how much added values such activities can create. It is considered as a method of cost management which is necessary far the survival management of real estate construction industry.

Due to the rapid development and dissemination of 5G communication and IoT technologies, there are increasing demands for big data analysis techniques and service systems. In particular, explosively growing demands on AI technology adoption are also causing high competitions to take advantages of machine/deep-learning models to extract novel values from enormously collected data. In order to adopt AI technology to various research and application domains, it is necessary to prepare high-performance GPU-equipped systems and perform complicated settings to utilze deep learning models. To relieve the efforts and lower the barrier to utilize AI techniques, AIaaS(AI as a service) platform is attracting a great deal of attention as a promising on-line service, where the complexity of preparation and operation can be hidden behind the cloud side and service developers only need to utilize the high-level AI services easily. In this paper, we propose an AIaaS system which can support the creation of AI services based on Docker and OpenFaaS from the registration of models to the on-line operation. We also describe a case study to show how AI services can be easily generated by the proposed system.

The rapid expansion of the Internet has provided users with a diverse range of services. Most Internet users create many different IDs and passwords to subscribe to various Internet services. Thus, the SSO system has been proposed to supplement vulnerable security that may arise from inefficient management system where administrators and users manage a number of ms. The SSO system can provide heightened efficiency and security to users and administrators. Recently commercialized SSO systems integrate a single agent with the broker authentication model. However, this hybrid authentication system cannot resolve problems such as those involving user pre-registration and anonymous users. It likewise cannot provide non-repudiation service between joining objects. Consequently, the hybrid system causes considerable security vulnerability. Since it cannot provide security service for the agent itself, the user's private information and SSO system may have significant security vulnerability. This paper proposed an authentication model that integrates a broker authentication model, out of various authentication models of the SSO system, with a multi-agent system. The proposed method adopts a secure multi-agent system that supplements the security vulnerability of an agent applied to the existing hybrid authentication system. The method proposes an SSO authentication model that satisfies various security requirements not provided by existing broker authentication models and hybrid authentication systems.

Vehicle inspection is a system to help all vehicles function safely through periodic maintenance. Vehicle inspections have been performed since 1962 in Korea by the government in order to reduce traffic accidents due to vehicle defects. Also, vehicle inspections may help protect citizens against uninsured vehicles and illegal vehicle remodeling by discovering and disclosing those vehicles. The prime objective of vehicle inspection is to guarantee all vehicles drive safely on the road by inspecting and fixing items which can affect traffic accidents. In addition, vehicle inspections may help to improve the public order related to vehicle operations and prevent crime through the confirmation of vehicle identity and authentication of ownership. Although there are many benefits of vehicle inspection. there are some negative opinions of the system. In this study, a methodology to analyze the effectiveness of the vehicle inspection system quantitatively in terms of traffic safety was developed. According to the developed methodology. accidents were reduced by 23.735, which is 11% of the total number of accidents in 2005.

An Administrative Boundary is the basic of spatial information to cover geographical and regional area. Its importance has arisen in our society at the Smart world era. However, it is difficult to serve exact boundary's lines as administrative boundaries are based on the cadastre lines of land register ; these partly are overlay each other or has gaps. So, it Should be adjusted. But, the maintenance work of administration boundaries causes a conflict or confusion unless we offer concrete procedures and detailed plans previously. Therefore, a rational method is required to prevent side-effects such as confusion, disagreem ent and a conflict etc. In this Study, we present a method and 5 step procedures to make better use in a practical maintenance work. we researched on basic studies of Administrative boundary's concept, history. And we performed a field survey as well as analysis of current problems. considering these results, we suggest usage of various spatial data sources, stake-holders' participation, a method of Nearest district's boundaries to maintain administrative boundaries. Throughout the method, we expect it to serve correct boundary-data to various fields without a big confusion. it is also useful to apply its results not only for re-surveying our land but for recording appropriate boundary-data as rational lines.

EBooks refer to electronic versions of books which are accessible via internet with forms of digital texts. In recent years, Amazon's Kindle digital eBooks has revealed the possibilities of success of the e-book market, which leads other companies to launch eBook service such as Google's eBook stores and Apple's iPad and eBook service. These reveal that the eBook market is finally showing a substantial amount of growth. Although the issue of technical support of eBook copyright protection emerges from the fast growing eBook marketplace, current technic of commercial DRM for protecting eBook copyright protection still has problems of non-comparability. Therefore, with the current technical status, DRM comparability problems, which have already occurred in music DRM environment, would also happen in eBook environment. This study suggests a standard framework to support eBook DRM comparability. When development of the standard reference software for eBook DRM comparability is completed, the sources will be registered as shareware to be open to public.
