Recently, due to the temporary closure and isolation of facilities for developmental disabilities due to the prolonged COVID-19, the pain suffered by consumers is getting worse, and there is no clear solution due to the lack of information on inpatient services. Therefore, there is a need for a service system that can prevent institutional and psychological problems for consumers. The purpose of this study is to provide systematic inpatient treatment guides, post-discharge management, and correct education for children with developmental disabilities and their guardians. After deriving the needs and improvement factors of consumers through domestic service case analysis, we conducted co-creation with end-users using the double diamond methodology. A possible service concept was derived. Accordingly, a collaborative sharing app service was proposed, and the usefulness of the service was confirmed through the usability evaluation and verification of various stakeholders. It is expected that the results of this study will be utilized in the development of an assistance system for the developmental disability ward based on user experience.

정보시스템 개발노력의 상당수는 실패로 끝나고 있다. 최근 통계에 따르면 정보시스템 개발 프로젝트의 반은 실패로 끝난다고 한다［kaplan, 1998］. 이와 같은 높은 실패율은 시스템 개발을 위한 노력을 체계적으로 투입하지 못하고 개발 프로젝트를 관리하기 위한 노력을 단위프로젝트 차원에서만 집중시키는데서 연유한다고 생각된다. 다시 말해 장기적인 관점에서 개발조직의 역량 향상이라는 보다 근본적인 목표를 간과하고 있는 것이다. 이러한 점에 착안하여 소프트웨어 엔지니어링 분야에서는 정보시스템 개발과 관련'한 개발 조직의 능력을 향상시키기 위한 다양한 접근방법이 제시되고 있다. 개발조직의 개발 프로세스 성숙도를 진단하기 위한 측정도구로 개발된 카네기멜론대학의 CMM(Capability Maturity Model)과 ISO 에서 정의한 표준인 SPICE (Software Process Improvement and Capability dEtermination) 모델이 그 대표적인 예에 속한다. 그러나 이와 같은 모델들은 개발조직의 프로세스 개선을 위한 방향과 요건은 제시하고 있지만, 이를 조직 내에서 구현하기 위한 구체적인 방법이나 수단은 제시해주지 못하고 있다. 따라서 이러한 접근방법 역시 소프트웨어 엔지니어링 역량 이나 개발경험이 일천한 우리 현실에서는 부분적인 성과 이상을 기대하기는 어려웠다. 본 연구에서는 이와 같은 문제점이 개발 프로젝트와 관련된 경험이나 지식을 효과적으로 추출하고, 획득하고, 체계화하고, 시스템화하여 조직 내에서 활용하려는 노력이 부족한기 때문이라고 본다. 이에 본 연구에서는 개발조직의 역량 향상을 위한 지식관리적 접근 방법의 세가지 유형을 제시하기로 한다.>$Ca^{2＋}$ 는 뿌리에서, $Mg^{2＋}$ 는 잎에서 많았으며, $PO_4$$^{-}$ 는 과실과 줄기에서 많았다. 배지간에 따른 차이는 나타나지 않았으며, $K^{+}$, $Ca^{2＋}$ 및 $Mg^{2＋}$ 는10:0에서, $PO_4$$^{-}$ 는 8:2에서 각각 많았다.해 제품을 판매하였으며, 기업 및 제품이미지 제고를 위한 고객에 대한 서비스도 강화하고 있었다. 통신기기업체내지 소프트웨어 산업으로의 진출이 가능할 수 있도록 상호진출을 허용할 필요가 있다고 본다. 이를 위해서 우리 나라 정부 역시 미국처럼 새로운 통신개혁법을 만들 필요가 있다. 새로운 통신개혁법의 핵심적인 사항으로서 첫째, 통신과 CATV간의 상호진입을 허용, 둘째, 통신사업자가 통신관련 기기산업에 참여할 수 있는 규제완화를 허용, 셋째, 유아단계에 있는 소프트웨어 및 컨테트산업을 육성하는데 산업육성책 수립 등을 적극적으로 추진하여야 할 것이다. 그리고 현재 국내 재벌기업들로 구성되어 있는 기반산업을 지원하는 기술개발 지원체제와 육성정책을 소프트웨어 및 컨텐트의 응용산업으로 개편할 필요성도 제시되며, 이를 위해 범부처 차원에서 소프트웨어 및 컨텐트 육성정책을 지원하는 종합적인 대책을 마련해야 한다고 본다.서, Li-K, Li-Na탄산염에 대하여 부 식거동을 검토한 결과, 가압하에서 내식성이 향상되는 것이 발견되었다. 이유로서는 가압하에서 용융탄산엽의 증가된 산화력으로 보다 치밀한 내식성 산화물 피막이 형성되기 때문으로 생각되고 있다. 또

Currently, registered number of imported vehicles is increasing rapidly over the years. Accordingly, environment improvements of vehicle maintenance company for maintenance of luxury vehicle such as imported vehicle are continuously being made. In this paper, we propose a key frame extraction method based on HSV color model for smart vehicle management system implementation to offer for customer reliability of maintenance vehicle. After automatically recognize the license plates of the vehicle using vehicle license plate recognition system when the vehicle come in the car center, we check the repair history and request of the vehicle based on it. We implement mobile services which provide extracted key frame images to the user after extract key frames from vehicle repair video. In addition, we verify the superiority of key frame extraction method by applying a smart vehicle management system. Finally, we convert the RGB color to HSV color to improve the performance of proposed key frame extraction scheme. As a result, we confirmed that our scheme is more excellence about 30% in terms of recall than RGB color model from the performance evaluations.

Event-based service technology integrate service to detect events that occur in real time by analyzing the response. Is the core technology for real-time business and ubiquitous service environment construction. Is required event-based service technology on business processes in real-time business environment that providing rapid response to changing and custom service using a variety of information real-time monitoring and analysis in ubiquitous service environment. Last event-driven business processes can be used as a CEP(Complex Event Processing). The core of CEP technology, the event from multiple event sources analysis of events affecting and the way to handle action, is detect complex event to user. In previous studies, an event occurs that continue to perform without the need for partial operations. so many operations and spend a lot of memory is a problem. To solve these problems, event detection technique is proposed that large streams of data without processing any events, registered to configure a complex event occurs when all events in the application layer, complex event processing. The proposed method, first using a bitmap index to manage the event occurs. The complex events of the last event in response to define a trigger event. The occurrence of an event to display a bitmap index, a composite event occurrence of all event to configure the test through the point at which a trigger event occurs. Is proposed, If any event occurs to perform the operation. The proposed scheme perform operations when all event occurs without events having to perform each of the tests. As a result, avoid unnecessary operations and reducing the number of events to handle the increased efficiency of operations.

Recently, with the development of IT technology, there is an increasing interest in cloud services as the number of users using mobile devices such as mobile phones and tablets is increasing. However, there is a need for techniques to control or control various methods of accessing data as the user's service demands increase. In this paper, we propose a dual key based user authentication model that improves the user 's authentication efficiency by using two keys (secret key and access control key) to access the users accessing various services provided in the cloud environment. In the proposed model, the operation process and the function are divided through the sequence diagram of the algorithms (key generation, user authentication, permission class permission, etc.) for controlling the access right of the user with dual keys. In the proposed model, two keys are used for user authentication and service authorization class to solve various security problems in the cloud service. In particular, the proposed model is one of the most important features in that the algorithm responsible for access control of the user determines the service class of the user according to the authority, thereby shortening the management process so that the cloud administrator can manage the service access permission information of the user.
