There exist a number of information systems planning (ISP) methodologies. Historically these methodologies have been evolving to reflect new technologies and business requirements. In fact, it is an uneasy task to select a methodology that fits a business need. Though there have been a number of studies proposing new ISP approaches, we are unable to find much research doing a comparative analysis on existing ISP methodologies. Our study, therefore, is to present a classification scheme for ISP approaches and to provide a guideline framework for selecting an approach most suitable to a particular firm's need. Our classification utilizes types of components covered in ISP deliverables and the peculiarity of these components. Such classification scheme and selection framework would help derive an IT-driven new enterprise model more effectively.

This study attempts (1) to analyze the changing pattern of organizational control by investigating the impacts of ERP implementations on the determinants of organizational control types and (2) to compare the performance variances based on the fitness between implementation of ERP and the changed mode of organizational control. Research results reveal that firms with ERP shows high degree of information integration, which partially affects the determinants of organizational control types. Also, results indicate that firms now with ERP shows the higher levels of both behavior and output control than without ERP, and the magnitude of change in behavior control level was greater than that of output control level. Finally, this research suggests that while the firms that implemented ERP for the purpose of quality and service improvement need to more focus on behavior control than on output control, the firms for the purpose of cost reduction need to excercise more output control in order to establish a cost effective control strategy.

The purpose of the paper is twofold. First, we revise the well-known Centering Theory of anaphora resolution and propose the controlled Information Packaging Theory (for short, CIPT). Second, we suggest a solution to the resolution of the antecedents of pronouns within the framework of CIPT. For this purpose, we select a dialogue of hotel reservation as a domain-restricted discourse, and discourse, and discuss the characteristics of the distribution of pronouns. We suggest that we need to palce the Slot-Link element on the top of the forward centering list. We claim that we need to establish a constraint on conceptual compatibility. As for the pronouns in the global dialogue, we propose a constraint of discourse command.

Considering the localization estimation issue in mixed line-of-sight (LOS)/non-LOS(NLOS) environments based on received signal strength (RSS) measurements in wireless sensor networks, a grid-based correlation method based on the relationship between distance and RSS is proposed in this paper. The Maximum-Likelihood (ML) estimator is appended to further improve the localization accuracy. Furthermore, in order to reduce computation load and enhance performance, an improved recursively version with NLOS mitigation is also proposed. The most advantages of the proposed localization algorithm is that, it does not need any prior knowledge of the propagation model parameters and therefore does not need any offline calibration effort to calibrate the model parameters in harsh environments, which makes it more convenient for rapid implementation in practical applications. The simulation and experimental results evidence that the proposed localization algorithm exhibits good localization performance and flexibilities for different devices.

Three most popular information services, Periscope, Ustream, and YouNow, vicarious for all Social Live-Streaming Services (SLSSs), are investigated to analyze their streamers' motivations and the user-generated content. Additionally, we collected demographic data (gender and age). More than 7,500 streams by users from the U.S., Germany, and Japan were observed. Main streamer motivations on SLSSs are boredom, socializing, the need to reach a specific group, the need to communicate, and fun. Important content categories on all three SLSSs are chatting, sharing information, 24/7, and 'slice of life.' We were able to identify differences between users from the U.S., Germany, and Japan as well as between the users of Periscope, Ustream, and YouNow. The main motive to stream in the U.S. is to reach a specific group, while in Japan it is socializing, and in Germany boredom. The top content category for both, YouNow as well as Periscope, is to chat; on Ustream it is 24/7 (i.e., webcams).

인터넷을 기반으로 하는 정보방송 서비스가 널리 확대되고 있으나, 인터넷 프로토콜 고유의 한계로 인해 사용상에 제한이 있다. 본 논문에서는 기지국에 IP 주소변환 기능을 도입한 억세스망에서의 인터넷 방송 기술이 제안되었다. 수신기에 IP 주소가 할당되지 않아도 되며, 사전에 서버의 주소를 몰라도 정보를 수신할 수 있으며, 서버의 부하나 통신망 트래픽이 대폭 감소되는 장점이 있다. 본 기술은 특히 무선 인터넷 지역방송에 매우 적합하다.

On account of the text based mail system has it's limit to support multimedia applications, GUI based mail system platform was developed to control document flow and automatize information process. The existing mail systems's to transmit data must need additional functions to automate document flow control. The platform of document flow control is deeply related to EDMAS(Electronic document Management System), workflow, Electronic Banking, DMS(Document Management System) automation, so it needs an ability to control proper data and document correctly. To resolve this problems, we are need of browser and engine to design work flow and to control documents flow. In this paper, we develope a mail browser to design document flow by follow user's requirements. This system can generate executive script code for document flow, and we add the function of workflow and process management to automatize the document flow in this system, and then we implement this Data flow engine.

The objective of the study was to evaluate the impact of the Call System of agricultural extension services in Korea. The respondents were satisfied on the speedy solution (74.5%), consultation (88.4%), and accessibility (79.7%) of the call system. However, satisfaction of farmers on in-depth consultation was higher (74.3%) than the satisfaction rated by the public servants of RDA (48.9%). Both groups replied positively (70.4%) on the need for expansion of the call system. The analyses of the results leads to a conclusion that there is a need to increase marketing on the importance of RDA's Call System to customers of agricultural extension and to improve accessibility through expansion of the system in other areas. These could solve the decreasing number of extension professionals and improve the quality and efficiency of extension services. These analyses may be useful as bases for a nationwide Call System that connects the center with other districts and for planning a renovation of information-oriented agricultural extension services. The issue that needs improvement is to abandon the grounds of agricultural technology information provider and respond to the customers' needs efficiently by building an established Call System which can minimize the side effect of the trends of reforming and downsizing the organization. It is needed to develop a unified management Call System of agricultural technology information that could provide real-time information, and database the results simultaneously for use as feedback to the Rural Development Programs. Related laws and policies need to be improved to establish a nationwide information network that maximizes the current network in agricultural regions to spread information, to provide institutional support, and to encourage development of training system and research and development by concerned institutes.

메타데이타를 위한 검색모델은 질의에 사용자의 정보요구를 정확하게 반영하기 때문에 정확율(precision)은 높지만 질의 조건에 만족하지 않는 정보를 배제하므로 재현율(recall)은 낮다. 반면 전문(full-text) 텍스트 검색 모델은 사용자 질의에 대하여 모든 문서를 검색대상으로 하므로 정확율은 낮고 재현율은 높다. 메타데이타 검색모델의 높은 정확율은 사용자가 메타데이타의 구조적 특성에 맞게 질의를 구성할 경우 가능하지만 일반적으로 사용자가 메타데이타의 구조 정보를 반영한 사용자 질의를 구성할 수 있다고 기대하기는 어렵다. 또한 메타데이타에 포함된 정보의 양은 전문 텍스트가 가진 정보의 양보다 적기 때문에 텍스트를 검색한 결과보다 재현율이 떨어진다. 본 논문에서는 이러한 특성을 반영하여 메타데이타 검색 시, 사용자의 다양한 질의를 메타데이타의 특성에 맞게 재구성하고 메타데이타뿐 아니라 텍스트에 대해서도 검색을 수행하여 두 모델의 장점을 함께 고려한 통합 검색 모델을 제안한다.
