With rapid spread of handheld devices like cellular or smart phones, a short message service (SMS) comes on the public as a communication means. SMS is very cheap and can be easily written down on the storage in order not to forget it, hence it is widely used to inform schedules (time and place). In this paper, we develop a system for automatically registering schedules extracted from SMS text messages. SMS text messages are very short and concise, but include a lot of Internet words like slangs and abbreviations. These have made it difficult to extract information on schedules from them. Also handheld devices have some limitations on computing power and storage and then applying general natural language processing modules like morphological analysis to the devices are somewhat hard. To relax these burdens, we extract schedule informations from SMS messages using machine learning methods like condition random field (CRF) without using any language processing modules and register the informations on the schedule management system of handheld devices. Our proposed automatic schedule registration system has implemented on Samsung Omnia phone for experiments.

The implementation of cellular phone based applications have been growing very fast because of WIPI which is a hardware independent platform. In this paper, we design and Implement a system to combine the animation avatar and e-mail service by using WIPI platform. Also, this system manages scheduling at the same time. This system uses SMS service in order to notify scheduled time and it synchronizes the schedule data with Outlook Express on the computer.

3D and BIM technology are presumed to be used more and more in the construction industry. The scope of this paper arose from a general wondering of how the constructor in general can benefit from the use of 3D models. Presented herewith is the first application of BIM in Korea to a actual bridge construction site located in Cheongpoong in Chooncheongbook-Do. This paper tries to integrate design, cost and schedule under location-based conditions with industry-specific solution for 3D modeling. 292 activities constitute the cable-stayed bridge of 442m long with a main span of 327m long. Integration of 3D model, cost and schedule is shown by comparing the measurements of works at a specific time by use of 2 different construction sequencing scenarios and cost breakdown structures.

In modern society, there is a tendency to emphasize efficiency and lead to detailed planning of team projects and individual tasks within organizations. In a 24-hour routine, the ability to use time effectively is considered an indicator of conscientiousness, and people try to imitate planned and organized people and utilize various systems to manage their daily lives. The reason why you want to perform a given task efficiently is because it affects the success or failure of the project by completing the task within a set period of time. Neglecting the project schedule is considered a major risk that threatens a successful outcome. This applies not only to large-scale organizational projects but also to individual life, and utilizes a variety of schedule management tools that emphasize time-based efficient management. In project management, it is necessary to carefully understand the detailed work progress rather than simply based on Today. In this paper, we propose an Android application that can manage schedules by accessing the user's project in units of tasks rather than dates, and introduce its implementation. The application we implemented in this paper can manage the project's goals and schedule by registering the project to which the user belongs. In addition, it provides the ability to approach work efficiently by visualizing the progress of the entire project or individual goals. As a result, users can use the application we propose in this paper to focus on their projects and manage schedules by task, thereby improving the overall efficiency of the project.

Retention schedule is the most essential tool for accurate documentation of government activities. The purpose of this study is to provide a guideline for redesigning retention schedules to support systematic documentation of government activities, that can replace the existing retention schedule ('bunryukijunpyo'). This present paper begins with articulating the role of retention schedules in life cycle management of records based on ISO 15489. And it compares and analyses 'disposal authorities' of Australia, 'records schedules' of United States. and the existing records retention schedules of Korea, in terms of types, structure and components of retention schedules. Based on these analyses, it suggests directives to redesign the retention schedules at the state level.

Smartphone schedule management applications are widely used in mobile environment with the help of their effective user interface and high user accessibility. Unfortunately, since the applications do not consider frequent context changes like user status or location, they can not support schedule management which reflects the changes. In this paper, we propose an intelligent notification service which gathers context information of users such as location and status, and actively provides appropriate services according to the context information. Based on the notification service, we also present a smartphone application for smart schedule management. Using the GPS sensor of a smartphone, the service can be aware of the status of the user through location and schedule information of the user. Also, according to the changed contexts, it provides proactive notifications to user.

접근제어는 권한이 있는 사용자에게 데이터에 접근할 수 있도록 제한하는 것을 말한다. 본 논문에서는 웹 주소록과 일정관리 기능을 여러 사용자가 공유할 수 있게 하기 위해서 접근제어 기법을 적용한 웹사이트를 개발하였다. 접근권한을 기술하기 위하여 그룹의 개념을 도입하여 그룹일정에 대해서 공유범위를 설정할 수 있게 하였다. 한편 주소록과 일정관리 데이터를 vCard와 vCalendar 등의 마이크로포맷 표준을 도입 하였다. 그리고 최근 웹 2.0 기술로 주목받고 있는 루비 온 레일스(Ruby on Rails) 프레임워크를 사용하여 구현 하였다.

Earned value management(EVM)는 프로젝트 진행 상태를 파악하기 위해 주로 비용과 일정 편차, 성과지표를 통합하여 분석하는 것으로 비용/원가 관리를 위해 발전되어 사용되어 왔다. 그러나 최근에는 경영환경 변화에 따라 불확실성이 증가하여 프로젝트 전체 일정의 예측에 대한 성과지표로 사용되고 있다. 본 연구에서, 비용관점에서 분석된 earned value management의 성과 지표와 시간관점에서 분석된 earned schedule의 성과 지표를 비교하여 차이점을 도출하고 비용관점에서의 지표가 프로젝트 전체 일정을 예측하는 것에서는 신뢰성이 떨어지는 현상을 발견하였다. 향후 본 연구를 통해 프로젝트 비용관리와 더불어 earned schedule의 성과 지표를 이용한 일정 예측을 통해 성공적인 프로젝트 수행에 도움이 되도록 하고자 한다.
