Patients with schizophrenia have thinking disorders such as delusion or hallucination, because they have a deficit in the ability which to systematize and integrate information. therefore, they cannot integrate or systematize visual, auditory and tactile stimuli. In this study, we suggest a virtual reality system for the assessment of cognitive ability of schizophrenia patients, based on the brain multimodal integration model. The virtual reality system provides multimodal stimuli, such as visual and auditory stimuli, to the patient, and can evaluate the patient's multimodal integration and working memory integration abilities by making the patient interpret and react to multimodal stimuli, which must be remembered for a given period of time. the clinical study showed that the virtual reality program developed is comparable to those of the WCST and the SPM.

Recently great construction companies strive for utilization of integrated safety management information in advanced IT in many fields. And construction companies have a interest and effort to construct system for integration and management of safety management information. Some earlier companies are appling to construction site ,but that is limited great construction company But it need to solve the origin problem because of it continually keep up the rate of disaster. Namely management system need more manage subcontractor that safety management in construction site. This purpose of study is an offer of foundation data to introduce and improve of safety management Information system. The paper is supposed to choose the essential regular items and going to propose improvement of safety information system according to the survey

다중 데이터베이스 시스템은 분산되어 있고 이질적이며 자치적인 데이터베이스 시스템들의 연합이다. 다중 데이터베이스의 환경에서는 공간적으로 데이터들이 분산되어 있고, 자료의 특성에 따라 서로 다른 데이터 모델에 의해 데이터베이스가 구축되어 있으며, 독자적으로 각각의 데이터베이스 시스템에 의해 관리되고 있다. 이러한 환경하에서는 정보를 효율적이고 종합적으로 관리하고 공유할 필요가 있으며, 이에 따라 사용자 관점의 논리적인 통합이 이루어 질 수 있을 것이다. 이러한 논리적인 통합을 위해 분산된 그리고 자치적이며 이질의 데이터베이스를 통합하기 위한 통합 데이터 모델이 요구되며, 이러한 통합 데이터 모델에 의해 완전하고 일치된 정보 모델이 제공될 것이다. 본 연구에서는 객체-관계형 데이터 모델을 토대로 하여 분산·이질·자치적인 데이터베이스들을 효율적이고 종합적으로 통합하기 위한 효과적인 방안에 대하여 연구하였다.

KASS (korea augmentation satellite system) is an SBAS (satellite based augmentation system) that must ensure the performance of aviation service in accordance with the International Civil Aviation Organization's SARPs (standards and recommended practices) Annex 10 - Aeronautical Telecommunications. In order to guarantee the target service performance, the operating system must be operated, maintained and managed stably, and a maintenance system must be established for this purpose. From the maintenance point of view, the KASS subsystems were developed to consist of replacement units, and the maintenance organization and procedures to manage those subsystems and units were defined. In addition, the maintenance task for each the replacement unit was developed to ensure the availability performance required for the successful KASS operation, and the developed tasks were verified to sufficiently cover the activities to maintain the previously defined replacement units. The maintenance tasks developed through this study will be continuously verified in the actual operation preparation process prior to the full-scale provision of aviation services in the end of 2023, and will be updated accordingly.

KISTI-ACOMS ver. 2.0 has been distributed to more than 340 academic societies and used by more than 130 academic societies for 4 years since 2005 and still is desired for use by lots of other academic societies. But contrary to the desire and requests for system upgrades of academic societies, ACOMS has not been improved for last 3 years and some academic societies began to use domestic or foreign similar pay online peer review systems. In this paper, a new integrated portal service system is suggested in order to attempt national production cost-saving and quality improvement of academic information by creating and collecting high quality scientific and technologic academic information inexpensively. We come up with methodology of integration and utilization of a personal academic activity portal system interoperable with other services of KISTI, an open citation reference database automatically constructed by authors' activity and a journal evaluation system based on impact factor.

Development of air navigation and avionics technologies led to solve the problems that conventional ATM system had. The International Civil Aviation Organization developed the Aviation System Block Upgrades (ASBU) initiative in order to harmonize global ATM planning and technology upgrades and urged to implement the recommendations for the member States. The ASBUs provide the road map to assist air navigation service providers in the development of their individual strategic plans and investment decisions. In this paper, the operational concepts in 2 performance improvement areas, Airport Operations and Globally Interoperable System and Data in ASBUs, have been summarized. In Airport Operations area the new management technologies and required systems are presented for optimizing the traffic flow in airport area and terminal airspace. Data format standards and required systems presented for information integration and usage of the new system under Globally Interoperable System and Data area.

Smart home System is shirt-sleeve, the automatic control systems, computer network system and network communication technology in the integration of network intelligent home control system. Intelligent household will let users have a more convenient means to management of domestic equipment, for example, through the house, wireless remote control, touch screen phone and Internet or speech recognition control household devices, more can perform scene operation, make more equipment form linkage. In this paper, we propose the intelligent household various kinds of equipment within each other can communication, do not need to user command according to different state interactive operation, thus to bring the greatest degree of user efficient and convenient, comfortable and safe.

기업의 효율적인 정보시스템 구축은 정보화 사회에서는 반드시 필요하다. 또한 기업의 성장규모, 기업의 요구사항, 기업의 보다 향상된 업무를 위해 시스템은 능동적으로 구현, 확장, 재구성되어야 한다. 이를 위하여 중소 업체에서는 한 번에 많은 투자를 해야되는 종합 정보화 시스템보다는 생산 관리, 인사 관리, 회계 관리 둥 각각에 대해 프로그램들을 개발하여 사용하고 있다. 그러나 서로 각각 개발된 프로그램들은 그 활용도나 연관성 면에서 효율성이 떨어진다. 본 연구에서는 중소기업의 효율을 높이기 위한 통합 시스템을 설계하고 개발한다. 특히 시스템을 능동적으로 구현, 확장, 재구성되기 위하여, 시스템의 총체적 설계와 세부적 설계를 위하여 단계적 설계과정을 적용하는 구조적 설계를 하였으며 프로그램 내부 설계를 위하여 모듈화 방법을 사용하였다.
