In generating station, cable spreading design is a very important task, which is very much time consuming, due to the type of cable used in generating station is very diverse. The raceway means the cable line section from source equipment to destination, and consists of cable tray and conduit. The process of existing cable spreading design was written in by hand. Thereby, there are grossly inefficient gain such as cable omission and unfixed fill value by a personal and time investment. In this paper, we proposed and implemented the automated cable route design based flexible cable fill check in generating station, and proposed the automated cable route design can be calculated the cable fill with flexible changing of raceway. Some experimental result shows that implemented cable route design is well performed and conducted as the design specifications, and it will be able to reduce the cable spreading design time. 발전소 설비에서 케이블 포설을 위한 설계는 발전소 설비에 사용되어지는 케이블 유형의 다양한 형태로 인해 매우 많은 시간이 요구되고 매우 중요한 과제이다. 케이블 포설 설계 시 레이스웨이(Raceway)는 출발지(Source) 장비로부터 목적지(Destination) 장비까지의 케이블 트레이(Tray) 및 콘디트(Conduit)의 포설 구간을 의미한다. 기존의 케이블 포설 설계 과정은 모두 수기에 의해 작성되어 인적/시간적 투자손실이 크고, 케이블의 누락 및 케이블 오버필(Over Fill)과 같은 비효율적인 손실이 빈번히 발생한다. 따라서 본 논문에서는 효과적인 발전소 케이블 포설 설계를 위한 레이스웨이의 유연한 케이블 오버 필(Fill) 체크 기반의 자동화된 케이블 라우팅 경로 계산 알고리즘을 구현하였고, 제안한 자동화 케이블 라우팅 설계기법은 케이블 위치의 변화에도 유연한 레이스웨이 계산이 가능하다. 구현 결과, 케이블 라우팅 설계 프로그램은 발전소 케이블 포설 설계 사양을 준수하면서 케이블 라우팅 경로를 효과적으로 설정하고, 케이블 포설 설계 시간을 기존 대비 크게 단축하는 성능을 얻을 수 있었다.

Objectives : Clinical differences between elderly patients with early and late onset depression have been described although these have been inconsistent. We aimed to compare differences of clinical symptoms using the 17 items Hamilton Rating Scale for Depression(HAM-D-17) between two groups. Methods : Data of 175 elderly patients with a diagnosis of major depressive disorder according to DSM-IV from January 2005 to November 2009 were collected. Seventy five patients were early onset depression and one hundred patients were late onset depression. Depressive symptoms were assessed by the 17-item Hamilton Rating Scale for depression. Results : There were some differences in HAM-D-17 scores between early and late onset depression. Early onset depression patients scored significantly higher in retardation(t = 2.41, p = 0.017) and somatic symptoms( general)(t = 2.37, p = 0.019) than late onset depression patients. Conclusion : We concluded that early onset depression patients have more severe psychomotor retardation and general somatic symptoms than late onset depression patients in Korea. Because of some limitations of this study, further investigations will be needed to validate this study results.

본 논문에서는 발전소 전기설비의 설계 중 케이블 포설 설계가 효과적으로 이루어질 수 있도록 케이블 포설 알고리즘 개발 및 자동화 프로그램을 구현하였다. 기존의 케이블 포설 설계 작업이 수기로 작성됨에 따라 케이블 누락 및 기준치 이상의 케이블 포설 등 불필요한 오류가 발생되어 인적 시간적 투자 대비 비효율성을 갖는 반면, 제안된 케이블 포설 자동화 프로그램은 케이블과 케이블 선로 구간을 코드화하여 효과적으로 과포설 계산 및 선로 구간을 변경할 수 있도록 하였다. 실험 결과, 구현된 케이블 포설 자동화 프로그램은 설계 규격대로 수행됨을 확인할 수 있었고, 프로젝트의 규모에 따라 하루에서 한 달 이내로 설계기간을 줄일 수 있어 발전소 전기설비를 위한 케이블 포설 설계를 경제적이고 효과적으로 할 수 있을 것으로 사료된다. In this paper, we proposed and implemented the automated cable-spreading program which can be done effectively cabling plan for electrical equipment in power plant. Cause the process of existing cable-spreading design was written in by hand, there are grossly inefficient gain by a personal and time investment with cable omission and unfixed overfill value. Proposed automation program for cable-spreading, which is coded cable and raceway, can calculate the overfill value and raceway change. Some experiments are conducted so as to verify the proposed model, and as a result, implemented cable-spreading program is well performed.

Methods : The author performed several experimental items, including arthritis evaluation, change in weight, spleen size and stenosis rate, change in cytokine level, IgG, IgM and anti-collagen II, change of immunocyte count and histological change of the CIA mouse joint. Conclusions are as follows: Results : 1. In the CF-HA, the arthritis index and rate and the incidence of arthritis were decreased as the experiment proceeded. 2. In the CF-HA, spleen swell and stenosis, joint edema and change were decreased. 3. In the CF-HA, the level of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ and $IFN-{\gamma}$ in blood serum were significantly decreased. 4. In the CF-HA, the level of IgG, IgM and anti-collagen II were decreased. 5. In the CF- HA, $IFN-{\gamma}$, $IFN-{\gamma}/IL-4$, IL-10 of the culture fluid was decreased. 6. In the CF-HA, the cell rate of $CD3e^+$ and $CD45R^+$, $CD4^+$ and $CD8^+$, $CD4^+/CD25^+$ in spleen was similar to the cell rate of the normal group. 7. In the CF-HA, the cell rate of $CD4^+/CD25^+$, $CD45R^+/CD69^+$ in a lymph node was decreased as in the normal group. 8. In the CF-HA, the cell rate of $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ in joints was decreased as in the normal group. 9. In the CF-HA, the cartilage destruction and the inflammation cell growth in the H&E stain were decreased. The collagen fiber in the M&T stain were less destructed, therefore the result was similar to the normal group. Conclusions : These results suggest that CH-HA at $ST_{36}$ has an effect in controlling immune reaction and suppressing inflammation in rheumatoid arthritis therefore, the continuous flow of the following study is expected.

최근 지능형 비디오 감시를 위한 다양한 연구가 제안되고 있음에도 CCTV 영상에서 이상 징후 판단이 사람에 의해 이루어지고 있어 상황인식을 위한 방법 및 연구가 필요하다. 본 논문에서는 이동물체 검출 및 추적을 위해 RGB 칼라 모델 기반의 색도 영상과 엔트로피 영상을 도출하여 그림자 제거를 수행한 후 이동물체를 추적하는 방법을 제안한다. 이동물체 검출을 위해 잡음 및 주위 환경변화에 민감하지만 순간적으로 발생되는 상황인지 환경에서 효과적인 차영상 모델을 적용하였다. 검출한 이동물체 영역에서 RGB 채널의 색도 영상을 기반으로 첫 번째 그림자 후보 영역을 선정하였고, 그레이레벨에서 엔트로피를 계산하여 두 번째 그림자 후보 영역을 추정하여 그림자를 제거하였다. 제안하는 방법의 타당성을 위해 고속도로에서 주행하는 자동차들을 대상으로 실험하였고, 실험 결과 색상과 엔트로피를 이용한 그림자를 제거와 이동물체 추적이 효과적으로 수행됨을 확인하였다. Recently, various research for intelligent video surveillance system have been proposed, but the existing monitoring systems are inefficient because all of situational awareness is judged by the human. In this paper, shadow removal based moving object tracking method is proposed using the chromaticity and entropy image. The background subtraction model, effective in the context awareness environment, has been applied for moving object detection. After detecting the region of moving object, the shadow candidate region has been estimated and removed by RGB based chromaticity and minimum cross entropy images. For the validity of the proposed method, the highway video is used to experiment. Some experiments are conducted so as to verify the proposed method, and as a result, shadow removal and moving object tracking are well performed.

실버세대의 모바일 폰 사용성 향상을 위한 GUI 디자인

박기홍 ( Ki Hong Park ),임경호 ( Kyung Ho Lim ) 커뮤니케이션디자인학회(구 시각디자인학회) 2011 커뮤니케이션 디자인학연구 Vol.35 No.-

At present, mobile phone is developing as information appliance with diverse functions due to convergence phenomena of technological advancement and information appliance. However, as diversification of functions required uses to have wide knowledge of complex functions and resulting in deterioration of usability of mobile phone. In particular, silver generation has a considerable difficulty in using complex functions of mobile phone. In addition, UI of mobile phone that has a direct influence on usability has been developed primarily targeting on young generation aged 20`s ~30`s and resulting in deterioration of silver generation`s usability. This study aims to find out the need of standardized GUI for silver generation to improve mobile phone usability of silver generation. Considering hardware performance of mobile phone released, it is possible for GUI design for young generation and standardized GUI design for silver generation to be loaded together. Therefore, this study aims to seek a way to develop standardized GUI for silver generation so that silver generation can use the function of mobile phone more conveniently and efficiently.
