In this paper, we developed a medical computer application for both disable children and adults in order to provide the chance to communicate easily with others. Although there are many mobile healthcare apps available nowadays, we believe that users should also have many options for choosing different types of healthcare programs developed for computers. That's why we have developed ConWis. This application helps a person with hearing loss, voice, speech, or language disorder to communicate easily with others. Through this software, hearing and understanding what is being said more clearly or to express thoughts become easier. To use this software, patient should input a sentence and it will be converted to audio speech using built-in voices for man or woman. In addition to that, it can convert voice that is received by microphone into text and display it on the screen.

본 연구에서는 한국인 표준체형과 유사한 사람의 의료 영상 자료를 이용하여 인체 골격계 모델을 개발하였다. 이를 동역학 해석 상용 소프웨트어인 RecurDynTM에 탑재하여 인체 시뮬레이션 모듈을 개발하였고 타당성을 검증을 거친 후 노인의 앉기-서기 및 보행 동작해석에 적용하였다. 노인이 보행기(elderly walker)를 사용하여 앉기-서기 동작을 할 때 하지관절 기구학의 변화는 미비하였으나 보행 시 각 관절의 가동범위가 감소하였고 동작시간이 증가하였다. 또한 근전도 해석결과 일부 발목 주변 근육들과 햄스트링 근육에서 근활성치가 줄거나 활성시간이 줄었다. 이러한 변화는 보행기를 이용한 보행 때 하지의 기여도가 감소했기 때문에 발생하는 현상으로 생각된다. 본 연구를 통해 얻어진 시뮬레이션 기술은 다양한 인체 정보 콘텐츠분야에 널리 활용될 것으로 생각된다.

모바일폰, MP3 플레이어, PDA와 같은 개인 휴대용 임베디드 기기가 다양해지면서, 각 기기의 부팅 시간은 제품 경쟁력을 위해 개발자가 고려해야할 중요한 이슈가 되었다. 이를 위해 Disable Console[1], Kernel XIP[2], IDENoProbe[3] 등의 기술이 제안되었지만, 부팅 시간의 80%를 차지하는 디바이스 초기화와 드라이버 등록에 대한 고려가 부족하다는 점에서 한계를 가진다. 본 연구에서는 부팅 시에 불필요한 IDE나 다른 인터페이스 채널의 초기화 과정 및 디바이스 드라이버의 등록과정을 생략하고, 그 과정을 부팅이 완료된 후로 지연시킴으로써 부팅 시간을 단축시키는 방법을 제안한다. 본 연구를 이용할 경우 부팅 시에 불필요한 IDE 인터페이스 채널의 초기화를 생략함으로써 기존 시스템의 부팅 시간에 비해 약 7초 정도 (일반 리눅스 부팅 시간의 약 14.15% 개선)의 성능 향상을 기대할 수 있으며, 나아가 부팅 과정의 80% 정도를 차지하는 디바이스 드라이버의 등록 과정의 일부를 생략하여 부팅 성능을 개선할 수 있는 실험적 근거를 제시하였다.

Because the brightness of an AMOLED is determined by the flowing current, each pixel of AMOLED operates via A current driving method. Therefore, it is necessary to supply power to adjust the amount of current according to THE user's requirement for AMOLED driving. In this study, an IP driver block was designed and a simulation was conducted for an AMOLED display, which supplies power as selected by users. The IP driver design focused on regulating the output power due to the OLED characteristics for the diode electric current according to the voltage to be activated by pulse-skipping mode (PSM) under low loads, and 1.5 MHz pulse-width modulation (PWM) for medium/high loads. The IP driver was designed to eliminate the ringing effects appearing from the dis-continue mode (DCM) of the step-up converter. The ringing effects destroy the power switch within the IC, or increase the EMI to the surrounding elements. The IP driver design minimized this through a ringing killer circuit. Mobile applications were considered to enable true shut-down capability by designing the standby current to fall below $1{\mu}A$ to disable it. The driver proposed in this paper can be applied effectively to the same system as the AMOLED display dual power management circuit.

In this paper, a 256Kb EEPROM IP aimed at battery applications using a single supply of 1.5V which is embedded into an MCU is designed. In the conventional cross-coupled VPP (boosted voltage) charge pump using a body-potential biasing circuit, cross-coupled PMOS devices of 5V in it can be broken by the junction or gate oxide breakdown due to a high voltage of 8.53V applied to them in exiting the program or erase mode. Since each pumping node is precharged to the input voltage of the pumping stage at the same time that the output node is precharged to VDD in the cross-coupled charge pump, a high voltage of above 5.5V is prevented from being applied to them and thus the breakdown does not occur. Also, all erase, even program, odd program, and all program modes are supported to reduce the times of erasing and programming 256 kilo bits of cells. Furthermore, disturbance test time is also reduced since disturbance is applied to all the 256 kilo bits of EEPROM cells at once in the cell disturb test modes to reduce the cell disturbance testing time. Lastly, a CG driver with a short disable time to meet the cycle time of 40ns in the erase-verify-read mode is newly proposed.

In this study, the fashion show of the disabled was hold for the universal fashion through the clothes which has relationship with personal mentality and behavior. There are several outcome of the fashion show. First of all, the main outcome is that through the fashion show the disabled fret that there is no difference between them and the ordinary people. Also, it is necessary to the revitalize the product development with universal fashion design. Secondly, the systematic succeeding study is necessary to solve the problem of the disabled and to set up the database management system in order to have a general idea for the their actual living condition and essentials of life for the disabled. Thirdly, even though the main purpose of the fashion show was to give them an opportunity to live fairly as a human being within their society, after the show, the necessity of social system to solve the additional problems and to continue the mental satisfaction comes. Fourthly, the disable have a tendency not to wear the special clothes for them since they want to be seen as the ordinary person. Finally, I suggest that there must be revitalization of a special design and the product development to reflect above mentioned points in addition to ordinary clothes.

This paper first presents two supply chain design problems: 1) a factory location setting and factory selection problem, and 2) a factory location setting and factory/supplier selection problem. The first involves a number of location known retailers choosing one factory to supply their demands from a number of factories whose locations are to be determined. The goal is to minimize the transportation and manufacturing cost to satisfy the demands. The problem is then augmented into the second problem, where the procurement cost of the raw materials from a chosen material supplier (from a number of suppliers) is considered for each factory. Economic beneficial is taken into account in the cost evaluation. Therefore, the partner selections will influence the cost of the supply chain significantly. To solve these problems, an agent gaming and genetic algorithm hybrid method (AGGAHM) is proposed. The AGGAHM consecutively and alternatively enable and disable the advancement of agent gaming and the evolution of genetic computation. Computation results on solving a number of examples by the AGGAHM were compared with those from methods of a general genetic algorithm and a mutual frozen genetic algorithm. Results showed that the AGGAHM outperforms the methods solely using genetic algorithms. In addition, various parameter settings are tested and discussed to facilitate the supply chain designs.
