  • Purpose: The purpose of this study was to investigate the activities of daily living (ADL) and instrumental activities of daily living (IADL) of residential home dwelling elderly and home for the aged dwelling elderly. In attempt to address medical professional caring the elderly, this comparative study examines the factors associated with dependence in the ADL and IADL in two samples of elderly people living in two different environments. Methods: The instrument of ADL and IADL widely used Katz ADL and IADL. Katz ADL and IADL was not a perfect fit for Korean. In concern with cultural factors Won developed K(Korean)-ADL and K-IADL scale reflecting Korean's own language expression and cultural factors in year of 2002. The assessment tool of this study was K-ADL and K-IADL. Differences of ADL and IADL were tested for statistical significance using group t-test and x2 test for comparisons between the residential home dwelling elderly and the home for the aged dwelling elderly. Results: Comparison of assessment for K-ADL and K-IADL in two different dwelling types was significant. Performance of ADL and IADL depend upon their living environment such as social status, number of children, income, present illness as well as age group. This study also showed significant differences of performance in some activities of ADL and IADL between the elderly who live in their own home and live in home for the aged. Comparison of performance of ADL and IADL in different dwelling types revealed that only one item of ADL was significant but only one item of IADL was not significant. It means that IADL is more difficult activities in the home for the aged dwelling elderly than the residential home dwelling elderly. The coupled elderly has more independent in some ADL and IADL activities compared with the single elderly. Conclusion: Using K-ADL and K-IADL is more convenient for Korean elderly. Medical professional consider some factors like dwelling style, social status, existing diseases and disabilities in order to care the elderly and train him/her activities of daily living as well as instrumental activities of daily living. Medical professional, especially physical and occupational therapist emphasize the training items which are bathing of ADL and grooming, housework, preparing meals, laundry, traveling, public transportation, shopping, using telephone and taking medicine of IADL based on the result of this study.

  • The purpose of this study was to investigate the relationship among functional evaluation systems, the Selective Motor Control Scale (SMC scale), the Gross Motor Function Classification System (GMFCS), the Gross Motor Function Measure (GMFM) and Activities of daily living in children with spastic cerebral palsy and to provide the foundation data about SMC scle for evaluation system of abilities of selective motor control in children with spastic cerebral palsy. For this, sixty eight children with spastic cerebral palsy were participated in this study. The children were evaluated by using the SMC scale for their selective motor control ability and by using the GMFCS and GMFM for their gross motor function. The activities of daily living were assessed by using the Functional Independence Measure of Children (WeeFIM). There were a significant correlation between the SMC scale and the GMFCS (r = -.485, p < .05). The good correlation between the SMC scale and GMFM was found (r = .482, p < .05). The activities of daily living were not a significant correlation with SMC scale (r = .019, p > .05). The SMC scale in practice will provide usefulness for assessment of abilities of selective motor control in children with spastic cerebral palsy.

  • This study examined the effects of action observations on the balance of patients with chronic stroke. The study period was between July 8, 2013 and August 10 2013. The participants were divided randomly into either the landscape picture observation group (n=20) and the action observation group (n=20). Each group observed the landscape pictures and video-recorded action-related balance for 5 minutes, respectively. Both groups had a balance training session for 10 minutes after the picture and video observations. The balance training sessions were repeated twice a day, three times a week for 6 weeks. As a result, significant improvement was noted in the action observation group than the landscape picture observation group for static balance and dynamic balance (p<.05). Consequently, the combination of action observation and balance training is believed to help improve the balance recovery for patients with chronic stroke.

  • 최근 컴퓨터 시스템에서는 동작 주파수 증가에 따른 전력 소모량과 높은 온도문제로 인해 CPU의 성능에만 의존할 수는 없는 상황이다. 이에 따라 GPU 병렬처리 연산능력을 CPU의 범용 데이터 처리에 이용하는 기술에 대한 관심이 높아지고 있다. 하지만 CPU와 GPU의 모든 자원을 활용하기에는 이에 따른 높은 온도와 전력 상승이 문제가 된다. 따라서 본 논문에서는 GPU의 전력효율과 성능 측면에서 최적이 되는 동작 주파수에 대한 분석을 수행하고자 한다. GPU를 활용하는 API인 CUDA를 이용하여 GPU의 동작 주파수 변화에 따른 성능 변화, 전력 변화 그리고 Energy Delay에 대해서 분석한다. 실험을 통한 분석 결과 동작 주파수의 증가에 따라 성능은 최대 30%이상 증가했고, 전력소모량은 최대 약18%의 증가를 보여주었다. 또한 Energy Delay도 최대 21% 향상되는 것을 확인할 수 있었다.

  • 긴급보호제어시스템(SPS, Special Protection System)은 일반적인 보호동작 범위를 벗어난 외란에 대해서 계통 전지역의 보호를 목적으로 하는 광역시스템 보호기술이다. 따라서 SPS는 외란 시에 계통 장비의 보호보다는 계통을 보호함으로써 전력 공급능력 향상에 주안점을 두게 된다. SPS는 자주 동작하지 않고 평소에는 대기 상태로 있으며, 긴급한 동작이 요구되기 때문에 많은 경우에 그 동작이 미리 결정되어 있다. SPS는 입력변수나 전력계통에의 영향에 따라 분류할 수 있는데, 입력변수에 따라서는 계통 응답에 기초한 SPS와 사고에 기초한 SPS로 나눌 수 있다. 발전기 탈락, 부하 차단이 SPS의 주요 보호 동작이며 이 외에 가스터빈이나 양수발전기 기동, AGC 제어, HVDC 고속전력변환, 분로기기의 자동스위칭 등의 제어 동작이 있다. 우리나라의 경우에는 주로 동기탈조 방지를 위한 발전기 탈락의 동작을 하는 SPS가 설치, 운전되고 있다.

  • 유기물/무기물 나노복합체를 사용한 비휘발성 메모리 소자는 낮은 공정 가격 및 높은 유연성 때문에 많은 연구가 진행되고 있다. 그러나 나노복합체를 사용한 비휘발성 메모리 소자의 형성 및 전기적 특성에 대한 연구는 많지만, 나노 입자가 포함된 고분자층을 이용한 플렉서블 유기 메모리 소자의 전기적 특성 및 동작 메커니즘에 대한 연구는 미미하다. 이 연구에서는 나노입자와 고분자가 혼합된 나노복합체를 유연성 있는 indium-tin-oxide (ITO)가 코팅된 polyethylene terephthalate (PET) 기판 위에 형성하여 비휘발성 메모리 소자를 제작하여 유연성 있는 기판이 휘어짐에 따른 전기적 특성과 기억 메커니즘을 설명하였다. 나노입자가 포함된 고분자층은 스핀코팅 방법을 이용하여 쉽게 형성한 후, 그 위에 금속 마스크를 사용하여 상부 Al 전극을 형성하였다. Al/나노입자가 포함된 고분자층/ITO/PET 메모리 소자의 전류-전압 (I-v) 특성에서 낮은 전도도와 높은 전도도를 갖고 있는 쌍안정성 동작을 관측할 수 있었다. 같은 조건에서 나노입자가 포함되지 않은 메모리 소자를 제작하여 측정한 I-V 특성은 쌍안정성 동작이 일어나지 않은 것을 관측하였다. 실험적 결과를 바탕으로 나노입자가 쌍안정성을 일으키는 메모리 저장 물질임을 확인할 수 있었다. 유연성 있는 기판의 휘어짐에 따른 I-V 특성과 스트레스에 의한 전도도 상태 유지 능력 측정을 수행하여 기판 휘어짐에 따른 전기적 특성과 안정성이 변화되는 것을 관측하였다. 측정된 I-V와 스트레스에 의한 전도도 상태 유지 능력 측정 결과를 기반으로 기억 메커니즘과 기판의 휘어짐에 따른 안정성을 설명하였다.

  • This study deals with reconfigurable modular robot with respect to the compact and capability of representing the various actions for promoting creativity through education and play. Generally modular robot can be designed as a suitable robot that is transformed to various structure by reconstructing each cells, However, there are only few research on the education and play using those robots in the world and still nothing domestically. Unlike the existing modular robots only having a repeating motion, the proposed modular works by individual module such as sound is produced by sound module, wheel is driven by wheel module, LED module controls the visual expression, power is supplied by battery module, bluetooth module for communication, and dynamic motion realization is possible by using joint module. By manipulating the abilities endowed by individual modules, diversity of creative activities is possible and thus made an easy access for children. This study deals with the design of modular robotic by using the variety of different modules to endowed the learning and playing ability. And the study showed the utility of the operating behavior over the actual production and testing.
