In Korea, telemedicine is still under the beginning stage, but we expect that the developing 'Information Highway' will make this technology more common place and more easily used in coming soon. Currently, three hospitals are providing telemedicine services with their subsidiary hospitals which are far away from their remote place. However, the fee schedule of telemedicine services are not well-settled down, of course not reimbursed through current health insurance system. This study aims to develop new payment system for medical services provided through telemedicaine system. To design appropriate fee schedule for telemedicine services, we, first, review the current insurance payment system and telemedicine system both in domestic and foreign countries focusing on its payment system. A framework of telemedicine payment system is proposed in following steps based on information we acquired from this stage. Second. We decide the span of cost items which should be covered by telemedicine payment scheme. In hear, we suggest payment method for telemedicine services should be designed as dual structure which are telemedicine fee that should be reimbursed through payment scheme and any costs related to capital investment that should not be covered by payment system. Which is, payment system for telemedicine services should cover only service-related costs and any costs related to capital investment should be generated through third party such as government, health insurance association, etc. Finally, we suggest new fee schedules for telemedicine services. The key issues on developing telemedicine fee schedules are related with the determination of appropriate additional rate($\alpha$). The reasonable additional rate($\alpha$) must determine through careful evaluation of any additional efforts(e. g. : additional work hours which are related to providing telemedicine services). This study shows the process of how to determine appropriate additional rate($\alpha$).

According to the Clinical Research Center for Dementia, 840,000 Koreans aged 65 or older had dementia patients, with a prevalence rate of 10.39%. The prevalence rate is one in 10 elderly people, but difficult for families to take care of them all day. Judged that possible to manage the conditions and schedules of elderly people living alone by utilizing AI speaker system where schedule management is stored. This paper implements modules for AI schedulers in patients with dementia. Configured to link AWS, a remote IOT, inside the raspberry pi, and to output the schedule to speakers using a calendar from Google API. Through this study, judged that ease of scheduling will help manage and schedule dementia patients.

The time and cost is the most important information for the construction project management. Currently, a lot of studies have been done in order to clearly relate them with each other, but there have been some difficulties. Because of the characteristic of Korean government contract law, the construction project in Korea is managed by only cost and the time and cost information is distinctly separated. In order to manage all the major construction project information smoothly, the time and cost information should have relation with each other. This study suggest methods for relating the time and cost information, especially for road construction project of MOCT. Through the survey of construction field engineers and case study of the road construction project, several alternatives to improve the usability of construction information are suggested in this study. These alternatives can support relating other construction information.

This paper designs an application for detecting various objects using a smart phone with camera sensor, then implements the application that detects the number of faces in front of a user by using the Face API provided by android and generates a speech to the user. For implementing the application, the GoF strategy pattern is applied to design the application. It provides some advantages; first, the algorithm development schedule can separate the whole application development schedule; next, it makes easier to add the algorithm. For example, another detecting algorithm for the other objects (character, motion detection) that may be developed in the future, or it may be replaced by a more high-performance algorithm. With the propose method, a general smart phone can make some advantages that can provide information of various objects (such as moving people and objects, and detected character from signboards) to the person who is visually impaired.

IEEE 802.11 Point Coordination Function (PCF) mode is defined to support time bounded traffic, such as voice in wireless LANs. The poll scheduling plays an important role in IEEE 802.11 PCF mode operation. This paper proposed a Multicast Polling Scheme (MPC) to increase the performance of wireless LANs. Moreover, we proposed a polling schedule scheme for our proposed multi-poll to serve real-time traffic. The results show that the proposed mechanism is more efficient than the original IEEE 802.11 PCF.

In this paper, we present a restricted tabu search(RTS) algorithm that schedules jobs on identical parallel machines in order to minimize the maximum lateness of jobs. Jobs have release times and due dates. Also, sequence-dependent setup times exist between jobs. The RTS algorithm consists of two main parts. The first part is the MATCS(Modified Apparent Tardiness Cost with Setups) rule that provides an efficient initial schedule for the RTS. The second part is a search heuristic that employs a restricted neighborhood generation scheme with the elimination of non-efficient job moves in finding the best neighborhood schedule. The search heuristic reduces the tabu search effort greatly while obtaining the final schedules of good quality. The experimental results show that the proposed algorithm gives better solutions quickly than the existing heuristic algorithms such as the RHP(Rolling Horizon Procedure) heuristic, the basic tabu search, and simulated annealing.

This article concerns the event management of the transportation and delivery system in the real time environment. Until now mainstream researches in the transportation and delivery area have largely focused how to create optimized vehicle routing schedule fast and stably, although the execution and event management area has a lot of opportunities which could make logistics efficient and especially customers satisfied. This paper suggests to-be model processes how to execute vehicle routing schedule correctly and when events are occurred how to cope with them effectively. To embody such ideas GIS, GPS and Mobile technologies are attached on optimizing scheduler engine, TMS, WMS, ATP and Monitoring system.

In many make-to-order production systems customers ask due date confirmed and kept. Unexpected urgent orders from valuable customers often requires short lead times, which causes existing orders in the production schedule to be delayed so that their confirmed due dates cannot be met. This Imposes significant uncertainty on the production schedule in a supply chain. In this paper, we propose a new concept of capacity reservation as a viable tool for due date promising and suggest its operational alternatives. Simulation results show that the reserved capacity scheme appears to outperform simple FCFS scheduling policy in terms of the number of valuable urgent orders accepted and total profit attained.

We propose a DVS technique for multiprocessor systems considering the energy consumed when translating voltage. We schedule periodic applications on two identical processors throughout a three-stage process; firstly, the computation energy consumption is minimized then the number of voltage translations is minimized. Finally, the result is compared with the schedule with no voltage translation and the one with smaller energy consumption is chosen. Overall, 10.6% energy reduction was achieved.

In this paper, we propose a method to improve Genetic Algorithm using Boltzmann selection which Michael has suggested. But Michael uses temperature schedule(the initial temperature, the cooling rate), which can be applicable only to the limited range of problems. We propose a new method to find the critical temperature and the cooling rate as parameters of the temperature schedule. The critical temperature can be derived from the distribution of each individual＇s fitness. Through the application of the island model where each island has differing cooling rate, it is proved that it is unnecessary to find the optimal cooling rate. The simulation on the TSP＇s with various city sizes proves the proposed critical temperature correct.
