The realization of u-City is coming near in some local governments by applying various city services, namely, u-City services to the city construction field to improve competitiveness of the city. But it is a reality that some local governments are experiencing many trial and errors in application of the u-City service in addition to the problem posing that the u-City service is not considering characteristics of development or application environment of an individual city. The present research proposes a service model for on-site application of the u-City service to solve this problem. The proposed model suggests a method for specifically conceptualizing and objectifying the on-site application that the existing concept-oriented model or an architecture-oriented model, etc. didn't provide. The verification system on effectiveness or effects of the u-City service model to remove ambiguity on the u-City service especially. The verification system of the u-City service model grasps the technology, function, procedure and target, etc. that the u-City service contains, evaluates whether the model satisfies conditions that the model should have, and secures objectivity and predictability of the u-City service model through confirmation on propriety, implementation and effectiveness, etc.

Increasing number of corporations applies IT service management systems to optimize IT service delivery and support processes. For this reason, implementation experiences and effect of IT service management system are growing concerns for IT managers and researchers. This case study analyzes implementation experiences on an ITIL based service management systems in an medium sized corporation. The exploratory case analysis revealed that systems and service quality were improved from the implementation. This study will contribute to the successful implementation of IT service management system and developing a research model of IT service management process.

웹 서비스는 WSDL 서비스 인터페이스와 서비스 구현 문서를 이용하여 정적으로 호출되거나 서비스타입 정의와 UDDI를 통한 서비스 구현을 검색함으로서 동적으로 호출될 수 있다. 지금까지는 동시에 두 가지를 수행 할 수 없었다. 본 논문에서는 Model View Controller(MVC) 프레임워크를 사용한 정적/동적 웹 서비스를 지원하는 효율적인 멀티미디어 CMS(Contents Management Systems)를 설계하고 구현하였다.

Since demand for location-based services increases and the relevant service becomes more diverse, the use of POI (Point of Interest) is being required in various fields. Various roles of POI for display, search and inquiry exist, but the implementation and expression of such roles are partially limited. Therefore, the data model for implementation is suggested in this paper to enable practical implementation, expression and inquiry of POI data. The data model was developed based on 3 roles of POI including search, expression and linkage, and especially, the spatial relationship between POI objects which was not suggested in previous data models is considered and time series scheme is suggested to enable various expressions and inquiries in application services.

This paper presents a new object model, LOM(Lightweight Object Model) and an implementation method for the distributed trader in heterogeneous distributed computing environment including mobile network. Trader is third party object that enables clients to find suitable servers, which provide the most appropriate services to client in distributed environment including dynamic reconfiguration of services and servers. Trading service requires simpler and more specific object model than genetic object models which provide richer multimedia data types and semantic characteristics with complex data structures. LOM supports a new reference attribute type instead of the relationship, inheritance and composite attribute types of the general object oriented models and so LOM has simple data structures. Also in LOM, the modelling step includes specifying of the information about users and the access right to objects for security in the mobile environment and development of the distributed storage for trading service. Also, we propose and implementation method of the distributed trader, which integrates the LOM-information object model and the OMG (object Management Group) computational object model.

챗봇서비스는 AI서비스와 연계하여 다양한 분야에서 활용되고 있다. AI에 대한 보안 연구는 초기 단계이고, 이를 이용한 서비스 구현단계에서의 실질적인 보안 연구는 더욱 부족한 상황이다. 본 논문은 AI서비스와 연계된 챗봇서비스에 대한 보안요구사항을 분석한다. 먼저, 본 논문에서는 최근 발표된 AI보안에 대한 논문과 자료들을 분석한다. 시장에서 서비스가 제공되는 있는 챗봇서비스를 조사하여 일반적인 구현 모델을 정립한다. 구현 모델에는 챗봇관리시스템과 AI엔진이 포함된 5개의 구성요소가 포함되어 있다. 정립된 모델에 기반하여 쳇봇서비스에 특화된 보호자산과 위협을 정리한다. 위협은 실제 운영중인 챗봇서비스 담당자 설문을 통해 챗봇서비스에 특화된 위협을 중심으로 정리한다. 10개의 주요 위협이 도출되었다. 정리된 위협에 대응하기 위해 필요한 보안 영역을 도출하였고, 영역별로 필요한 보안요구사항을 분석하였다. 이는 챗봇서비스 보안 수준을 검토하고 개선하는 과정에서 보안평가 기준으로 활용될 것이다.

Ubiquitous computing which is providing various convenient services to user will prevail in future. To realize ubiquitous service, analyzing technical and information factors for service implementation is necessary. This paper defines ubiquitous service model to satisfy user demands and we analyze technical and information factors in order to realize services. Based on the factors, we extracts and classifies common compositions of ubiquitous services to suggest guidelines of service design.

In this paper, we model management information for Internet service, and design and implement management architecture using CORBA and Web technologies. Concretely, we also extend WWW Service MIB so that it presents service management model which can manage WWW service effectively. We have developed management tool such as Map Editor and MIB Browser. SERVICE fault/performance/configuration management functions are also designed and implemented.

The emergence of convergence has been the cause of development of the industry more complex and difficult by continually changing business environment and the destruction of the business area. The government-initiatives approach shows the limits to foster the new industries in needs of service-oriented ecosystem. In this study, we propose the service model as service-based approach for the development of new industries derived through the convergence inter-industry. While business model is defined based on the company's temporary and piecemeal activities, service model is the concept of dynamic and continuous that includes national, industrial, corporate level. In order to derive the service model, to identify current problems and issues with the public and the private sector is first. Then design the roadmap for the implementation of the desired shape through strategy from optimal rationality and long-term strategy. In this study, we define a service model, and consider when establishing a service model for three dimensional(national, industrial, corporate level) through analyzed by 3Level Service Model. And we also consider characteristics of the service model and approach, present the case of 'New Transit Card Services in Seoul'.

Service industry has become the integral part of economy. And the activation of industry requires a scientific and systematic approach. As one of these kinds of efforts, IBM presented a service model which consisted of strategies, processes, technology, manpower and so on through Service Science. And IBM raised the needs of considering the main issue and methodology of service model's scientific approach. On that account, this study worked out factorial definitions and measurable items by the four components of service model presented by Service Science in order for it to be measured through studies on related literature and interviews of specialists. In order to prepare an opportunity of categorizing the conception of the service model of which character was strongly intangible and of systematically approaching to it, the investigator examined related literature and applied it QFD methodology. Through this kind of redefinition, the investigator concretely conceptualized the service model which was standstill at the level of theoretical approach so far and presented guidelines with which researchers could classify it more concretely. In addition, the investigator tried to present a systematic frame which could be applied to business by working-level officials or decision-makers. Therefore, the investigator expects that study findings will be used as references for the design or implementation of service-oriented business model.
