The applications for considering their position and daily patterns of dementia patients have been developed in an early stage even if the older patients who have weaker or serious symptoms has increased in various forms. In this paper, we develop an android-based application which displays positions and pathways of patients on maps and provide messages in the cases of dangerous situations. Guardians need to register schedules including safe areas and personal information of their patients. This system registers behavior status categorized as normal or abnormal each position which is sent to a database. In particular, the deviation status is assigned in case the patients are not within the safe areas that their guardians registered on their schedule. The wandering status is assigned in case the patients are repeatedly passed by their pathways. This smart application contains the modules such as patient position sending, guardian and patient information, patient schedule and safe zone registration, position and behavior status registration, pathway display and message sending, and rescue request. This system sends the notification and alarm service providing normal and abnormal behavior with deviation and wandering status of patients respectively.

Recently The public project ordering in local autonumous entities is a tendency increasing of CM service because of the visible and affirmative effect in the CM which is advanced meanwhile. And, the CM services of project all phase excepts a planning business are performed. To develop CM must be prepared the system plans concerned with the CM application from planning phase, actuality maintenance of CM fee-estimation standard, understanding conversion of participation subjects, the specialization through certification of CM qualification, etc. But, unexpected actuality the problems occurs when the CM business is performing. The purpose of this study are to present the solution to the problems concerned with the design management, design phase VE, additional business by owner, schedule control and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Susung Culture & Art Center.

EVMS(Earned Value Management System) came to the proper method for integrated cost-schedule control and Government announced EVMS application plan. After that, many studies related adaptability, activation, model, and process reflecting the characteristics of the domestic construction industry are proceeded in construction sites and schools. This thesis is a study of EVMS process. The purpose of this paper is to analyze the problems of previous researches for EVMS Process and to suggest the EVMS application Process based on Project Management Processes of PMBOK. In this kind of view, this thesis suggests the new direction to study EVMS process. And furthermore, this process is suggested for showing a framework of EVMS in Korean construction project are identified.

The System Engineering(SE) and the Earned Value Management System(EVMS), as parts of the scientific project management methodology, have been applied to Surion Helicopter R&D Program. The concept and application process of SE methodology, requirements management and applications output by DOORS program are described in this study. The concept and application process of EVMS, analysis results of schedule/cost variance for Surion RF equipment are also discussed in this study. Though the Surion R&D program is still on-going, it is found that the measures of effectiveness of SE and EVMS applications are verified.

A web application running on the Internet is causing many difficulties for a program developer, and it requires to process multiple sessions at the same time due to the occurrence of excessive traffic. Web applications should be able to process concurrent requests efficiently and in real time. Node.js is a single-threaded server-side JavaScript environment implemented in C and C ++ as one of the latest frameworks to implement event models across the entire stack. Nodes implement JavaScript quickly and robust to achieve the best performance using a JavaScript V8 engine developed by Google. In this paper, it will be explained the operation principle of Node.js, which is a lightweight real-time web server that can be implemented in JavaScript for real-time responsive web applications. In addition, this application was practically implemented through automatic alignment system for group scheduling to demonstrate event-based real-time response web processing.

Float has been just recognized spare time for disposing of unexpected conditions as by-product of CPM(critical-path-method) calculations, in spite of important method for construction period, taking in material, human supply and cost reducation in construction process management. Also float necessary follow method of contract by ownership problem and effect construct management of use. The purpose of this study was to examine current recognition and application grade of float in construction project. In addition, the study proposes improvement strategies of float application for efficient progress plan and control.

The path planning is done at the joint level. Cubic spline functions are used for constructing joint trajectories for industrial robots. For N-joint robot, Cartesian knots are transformed into N sets of joint displacements, with one set for each joint. For industrial application the speed of operation affects the productivity. An algorithm is developed to schedule the time intervals between each pair of adjacent knots such that the total traveling time is minimized subject to the physical constraints on joint velocties acceleration and jerks.

This paper deals with the scheduling problems, which are the most important subtask in High-level Synthesis. ILP(integer linear programming) formulations are used as a scheduling problem approach.For practical application to digital system design, we have concentrated our attentions on pipelined datapath scheduling. For experiment results, we choose the 5-th order digital wave filter as a benchmark and do the schedule. Finally, we can obtain better and near-optimal scheduling results.

Parallel Genetic Algorithms (GAs) are developed to solve a single machine n-job scheduling problem which is to minimize the sum of absolute deviations of completion times from a common due date. (0, 1) binary scheme is employed to represent the n-job schedule. Two selection methods, best individual selection and simple selection are examined. The effect of crossover operator, due date adjustment mutation and due date adjustment reordering are discussed. The performance of the parallel genetic algorithm is illustrated with some example problems.
