Today only 5-15% (approximately 1 in 10 persons) of persons with disabilities in need globally have access to assistive products which assist or replace the impaired functioning[1]. GATE (Global Cooperation on Assistive Technology) is a WHO global initiative for cooperation of stakeholders to cope with current and future challenges in product design, pricing, delivery and services, as well as medical and social system, expert training, and policies. This paper introduces the concept of WHO GATE to improve access to assistive technology for everyone by the cooperation with global key stakeholders.

본 논문은 한국어 보조동사의 의미를 Sowa에 의해 제안되고 국제표준이 되고있는 개념그래프를 이용하여 형식적으로 기술하는 방법을 제안한다. 이를 위해 영어의 양상과 상에 관한 개념그래프를 알아보고 한국어 보조동사를 통사/의미론적으로 고찰한다. 한국어 보조동사의 개념그래프적 기술을 위해, 각종 논문과 국어사전에서 한국어 보조동사 40개의 여러 예문들을 수집하여 완료, 진행, 봉사, 시도, 강세, 원망, 지속, 추정의 8가지 의미로 분류하고 이들을 개념그래프로 기술한다. 실험에서는 이들 8가지 의미들을 인공지능언어의 일종인 LIPS과 유사한 KIF로 작성하고 C++를 이용하여 한국어 보조동사가 포함된 문장을 입력받아 개념그래프로 변환하는 프로그램을 구현한다. 문장 내의 모든 범주들의 개념과 개념 관계가 자연어의 모든 의미관계를 표시할 수 있는 개념그래프는 한국어 보조동사의 다양한 의미를 기술하는데 적합함을 알 수 있었다.

R&D trend for Auxiliary Power Supply(APU) of electric vehicle can be well understood by analyzing patents at home and abroad. Based on this trend analysis, domestic technology development direction is proposed. To get technique trend, patents of Korea, Japan, Europe and America published until February of 2014 are analyzed by WIPS DB. First, power converter and transformer two big category are classified. Power converter can be classified into resonant DC to DC converter and resonant Half bridge inverter; transformer can be classified into high frequency transformer, ferrite transformer and matching transformer. By analyzing R&D trend of different counties, companies and years, specific technology needed to be developed and trend of technology can be accurately grasped.

Korean auxiliary verbs are often used in Korean sentences in spite of the small number of the auxiliary verbs, However. the incorrect processing of the verbs concept leads to the poor translation quality. To solve the problems of the auxiliary verb processing. the paper proposes a description of the auxiliary verbs based on Conceptual Graph (CG), For the description of the auxiliary verbs within CG. we first collect 40 Korean auxiliary verbs and example sentences from papers and a Korean dictionary, Next, we perform the analysis of the Korean auxiliary verbs through a classification: perfective, progressive, benefactive, attemptive, emphatic, desirable, retentive, and presumptive. Then we depict the eight meanings based on CG. In the experiment. the paper implements the program that translates sentences included in the auxiliary verbs into CG and explains the experimental results.

Korean auxiliary adjectives. causatives and passives are often used in Korean sentences in spite of the small numver of them. However, the incorrect processing of their concepts leads to the poor translation quality. To solve the problems. this paper proposes a description of them based on Conceptual Graph(CG). For the description of them within CG, this paper first collects 12 auxiliary adjectives, 425 causatives, and 260 passives. Next. the paper performs the analysis of them. Then the paper depicts the meanings of them based on CG, in the experiment, the paper implements the hepler program that translates sentences included in them into CG and explains the experimental results.

This paper reviews trends of the rehabilitation welfare devices on the basis of products and markets. Latest assistive devices tend to have a fold function. Auxiliary power assist module has been added. The completion of products has been improved. The folding function has strong relationship with portability. Specifically, various mobility devices, including foldable devices, are associated with enhanced portability. Powered auxiliary wheels and upper extremity supporting modules have entered the market. The leading-edge technology like Segway's control technology applies to two-wheel wheelchairs. The brand- new technology, lower extremity robotic exoskeleton, applies to markets. Standing wheelchairs, ramps, stair climbing assistive devices becomes more common. In addition, a combination of a variety of smart devices is being promoted to the classical assistive devices' part. Rehabilitation welfare devices can be more valuable due to nice industrial design, improved materials, and processing technology.

분산 비디오 기술의 대표적인 기술 중 하나는 와이너 지브 부호화 기술이다. 와이너 지브 부호화 구조에서 보조정보는 인트라 복호화된 키 픽처들을 이용하여 생성한다. 키 픽처의 객관적 화질은 보조정보의 성능에 많은 영향을 끼치고, 잡음이 많은 보조정보를 복호화에 이용할 경우 부호화로부터 많은 패리티 비트를 요구하게 되어 율 왜곡 성능을 저하된다. 기존의 부호화 기술은 키 픽처 부호화 시 Quantization Matrix에 따라 미리 정의된 양자화 계수를 이용한다. 본 논문에서는 미리 정의된 양자화 계수 보다 낮은 계수 값을 사용하여 부호화 하는 방법을 제안한다. 제안방법은 키 픽처의 객관적 화질이 높아짐에 따라 보조정보의 화질을 향상시킨다. 잡음이 적은 보조정보는 와이너 지브 복호화 시 율 왜곡 성능을 향상시킨다. 실험결과는 기존 방법에 비해 최대 0.7dB에 이르는 성능향상을 보인다.

This study was conducted to find ways to utilize human-centered IT in caring for elderly people who live alone. Through focus group interviews with experts, this study investigated the problems with delivery system, and ethical issues. Problems such as lack of trust, supplier-centered care, and uniform service provision were derived as major problems in the delivery system. These findings indicate that IT should be used as an auxiliary means of face-to-face services and to be controllable and convenient. Issues such as "guaranteeing the right to self-determination," "protecting privacy," "sufficiently guaranteeing the right to know," and "encompassing blind spots" were raised as important ethical issues related to human-centered IT utilization. Based on the research results, this study presented the necessity of designing user-centered information technology and the necessity of developing ethical indicators for the use of human-centered technology.
