In this paper, we introduce smart home service based on ubiquitous environment and context awareness. We define the multi- context environment and the context collision caused by many user that the existing study of smart home is unconcerned with. Heal home is the space where various contexts are created and disappeared in. Smart home appliances are restricted within their service. We divide the home space by main uses of rooms and group smart service by sensory organ. And we introduce the multi-context manager consist with context interpreter, context collision manager and smart service manager.

사용자가 시간과 장소에 구애 받지 않고 컴퓨터를 자연스럽고 효율성 있게 사용할 수 있는 환경을 의미하는 유비쿼터스 컴퓨팅은 네트워크와 센서(Sensor), smart devices, 무선 통신과 smart middleware(UPnP(Universal Plug and Play), Jini, HAVi(Home Audio Video Interoperability) IEEE 1394, PLC (Power Line Communication) 등) 등을 기반으로 Smart Space를 만들 수 있다. 그러나 여러 종류의 가전제품들이 늘어나고 수많은 사용자들의 요구를 충족시키기엔 smart middleware의 단일 제어로는 처리가 불가능하여 본 논문에서는 이기종간의 미들웨어간의 상호작용을 위해 개발된 OSGi(Open Service Gateway Initiative) Spec. 3에서 제공하는 서비스 플랫폼(Service Platform)을 기반으로 사용자/디바이스 관리 및 분산 시스템 등의 취약점들을 보완하여 Smart Space상에서 효율적인 서비스 번들을 관리하기 위해 MASBM(Multi-Agent Service Bundle Manager)을 제안하였다.

Korea National College of Agriculture and Fisheries start school at 1997 and 10 for 2,066 people graduate and is becoming the help in youth agriculture and fishery manager education. But recently according to industrial functional staff institutional abolition policy of the government is forecast with the fact that will have a failure to agriculture and fishery manager education. Korea National College of Agriculture and Fisheries was founded for a succession agriculture and fishery manager education. When but while attending military service is under and the education which is continuous is difficult. When after college graduating the reeducation for the agriculture which goes to the military service is necessary. Also Part of the graduate can not participate to agriculture and fishery. This is consistency lack of governmental policy and there is worry which will be criticized. According to FTA agreements the damage is forecast in agriculture and Fisheries. Also prevents the instability of the food supply and which follows in global environment change, respects the stable supply of the foodstuffs which is safe from the agriculture and Fisheries support of the nation is necessary. Consequently proposed the military service substitution institutional plan for the agriculture fishery successor.

Recently, the concern of the FTA (Free Trade Agreement) have shifted to the promotion of the professional service's trade via the bilateral and reciprocal agreement of its professional laws. In the construction industry, this policy has intended to make the standardization of the construction manager's profession in the world. The purpose of this paper is 1) first to define the general model of professions in the U.S., UK and Japan, 2) then to declare the construction manager's model of the profession in them to apply the general model of professions, and 3) finally to analyze the identity of Korean construction managers and acquirement of its construction manager's law comparing with construction manager's model of the profession in the U.S., UK and Japan.

In this paper, we propose a real-time remote logging model for development of android applications using LBS(Location based Service). The model has two major parts: Mobile Log Management Service and Remote Log Server. Mobile Log Management Service consists of the log collector and the remote log manager. The log collector is an aspect of AOP which can collect logs from the target application without modifications of source codes. The remote log manager has a background service component so that it can receive logs whenever the log collector captures logs from the target application. Remote Log Server communicates with Mobile Log Management Service by socket interface. Therefore, Remote Log Server can show logs in real-time. To validate the efficiency of the proposed model, we show a case study, and compare the model with other models.

Because of the change of computing environment, an agent technology is spotlighted recently. By deploying agent distributedly in network and offering the necessary service quickly in place easing realization of service, the enlargement of the effectiveness of network is necessary more and more. In this paper, agents programmed in java are distributed in place easing realization of service in network. And a manager connects to agents and informs URL of service code of the agent. This paper implements distributed computing environment in which agent downloads service code from URL of service code, executes the code, and returns the result of execution to manager.

An example of such a new device is a mobile phone. The demand for wireless data communication is growing rapidly. However, agencies have not yet completed the standardization of the markup language. Due to the evolution of the Mobile Device, the agencies in this field have provided different data formats with each Mobile Device Platform. Traditionally, contents are hand-tailored to suit the target devices. A key problem is that the characteristics and capabilities of mobile devices are too diverse to service the most suitable mobile contents. Owing to this problem, the need for a reusable document description language increases. In this paper, we defined Template file that is common data to service mobile devices. We proposed method that could be effective wireless web service though design and the implementation of the Call Manager & the XSL Generator. In the methodology, when requesting wireless internet service, the mobile device finds out Markup language and hardware specification of the mobile device through the Call Manager component supports. The XSL Generator component creates XSL file dynamically that is the most suitable to device. Finally, contents is serviced to each device by XSLT.

Construction Management is the overall management of the project as construction manager and the owner are united together. Construction manager's role is to conduct the overall or partial construction administration in the 'design, bid, build' process, in the owner's interests with maintaining technical neutrality. Construction manager is becoming one of new professionals in the building process and the contract defines their roles and the range of services, so high level of ethnics are required. This study suggests the legal status of the construction manager and the ethnic standards and the ethnic's characteristics. In conclusion, firstly, the legal characteristics of the administration of construction management are the delegations contract, the responsibility of negligence and the duty of due diligence, abided by the contract that ties between the owner and the construction manger. Secondly, the administerial characteristics of the construction management are the role of mediator, the service of professional technology, accountability to the owner and publicness. Thirdly, due to these characteristics, as a professional, the standard of ethnic assessment for the construction project manager are intention, act and result, so with the relation to that, morality, deontology and consequentialism have been suggested in this study.

This paper describes an Security Manager that integrally manages the Information Service related to RFID middleware, Object Name Service, and Web Service for upper level applications. In order to provide the access control of distributed RFID objects, Single-Sign-On has been implemented by extending existing UCON (Usage Control) model and SAML (Security Assertion Markup Language) assertions. The security technology of distributed RFID systems can be included in middleware and protect RFID information. In the future, it can be also applied to ubiquitous sensor networks.
