The Internet is standing in the spotlight of a new medium of advertisement with explosive growth of market share of electronic commerce, several Internet advertising methods have been implemented. Among them, the banner advertising method is typically being used in the Internet, but the users are not willing to see the banner advertising, moreover that method shows low click rate. Accordingly we propose a new Internet advertising method that makes expose advertising content according to proper text keyword in the article of web pages. During user is reading a article of web page, when user puts mouse pointer over a text keyword, previously specified advertising content is appeared on the web page. The proposed method is based on the keyword advertising, and unlike banner advertising, various shape of images can be applied. Also whole web page could be used for advertising area, and the method does not affect loading delay time of web page.

This paper aims at providing a shooter game interface which enhances the game's realism by recognizing user's hand gestures using the Leap Motion. In this paper, we implemented the functions such as shooting, moving, viewpoint change, and zoom in/out, which are necessary in shooter games, and confirmed through user test that the game interface using familiar and intuitive hand gestures is superior to the conventional mouse/keyboard in terms of ease-to-manipulation, interest, extendability, and so on. Specifically, the user satisfaction index(1~5) was 3.02 on average when using the mouse/keyboard interface and 3.57 on average when using the proposed hand gesture interface.

Phellinus linteus (PL)-hot water extract (PL-W) or- methanol extract (PL-M) was orally administered alone (single dose of 400, 800, 1600 mg/kg; 800 mg/kg/day for 5 days) or with cyclophosphamide (CY, 20 mg/kg, i.p.) to female ICR mice. Within PL alone-treated group, WBC and plaque forming cells (PFC) to SRBC were slightly and significantly enhanced when compared with control group. The relative thymus and spleen weights, WBC and PFC numbers were significantly decreased by the treatment of CY, whereas those values were markedly increased by the concomitant treatment of CY and PL when compared with CY administration alone. To assess the effects of PL and/or CY on the mitogen response of splenocytes io LPS, mouse splenocytes were stimulated with or without LPS in the presence of various concentration of PL and/or CY in vitro and splenocytes proliferation (SP) was measured by MTT assay. PL alone increased both SP and LPS- stimulated SP. Moreover, SP and LPS-induced SP suppressed by the treatment of CY alone were significantly restored by PL-treatment. These activities were higher by PL-M than by PL-W, These results indicated that PL was able to increase humoral immunity and to inhibit immunotoxicity induced by CY.

제스쳐(gesture)는 마우스 또는 스타일러스의 난일 표시(single mark)를 이용하여 객체들과 기능들을 식별하는 문서 편집 도구의 강력한 방법들 주 하나이다. 마우스를 위한 제스쳐는 주로 데스크 팁 기반의 환경을 위해 개발되어지고 스타일러스를 위한 제스쳐는 보통 휴대용 컴퓨터를 위해 개발되어진다[2]. 현대는 PDA(Personal Digital Assistant)시스템의 스타일러스를 위한 제스쳐 개발이 활발하게 이루어지고 있다.[3]. 하지만 PDA 시스템에서는 인식에 의한 문자 입력의 보조 도구 정도의 수준에서 제스쳐가 사용되어진다. 본 논문에서는 PDA 시스템에서 사용되는 키보드의 키 역할을 하는 기존의 제스쳐와는 달리 사용자 입력과 제스쳐에 차별을 두지 않고 한 화면에서 직접적이 제스쳐가 가능한 환경을 개발하고 다양한 제스쳐 인식 방법을 제안한다. PDA 시스템에서의 제약을 최소화하기 위해 펜 기반의 입력에서 각 스트록을 간략화시켜 정보를 최소호 한 뒤 각 스트록을 양방향 연결 리스트를 이용해 연결하였다. 제스쳐(gesture)는 삽입, 삭제의 기본적인 것들을 비롯하여 이동, 복사, 붙임과 같은 제스쳐도 포함되어 있다. 제스쳐(gesture)의 인식은 각 스트록의 바운딩 박스와 점들의 위치 정보, 스트록 생성 순서에 기반하여 이루어지기 때문에, 이로 인해 펜 기반의문서 에디터 사용에서 요구되는 다른 제약 없이 오로지 펜만으로 모두 편집 환경을 구현할 수 있다.

Due to the rapid development of information & communication technology under high performance computing environments, the multimedia production techniques have been applied to a variety of multimedia fields such as general banner advertisements including texts, images and animations, and the internet-broadcasting dealing with videos and sounds. This paper presents an authoring tool with main functions to setup events objects (image, animation, sound, button, area) and to setup action functions, so that non-experts can easily produce multimedia including images, sounds, animations and so on. The authoring tool implemented in Java can be applied to the CD-ROM title production as well as the web-site construction. We can expect that when this authoring tool is used for in multimedia production, both cost and time will be reduced due to its convenience and powerful functions. We have a future plan to integrate intelligent multimedia presentation techniques with the presented tool for the autonomous multimedia authoring works.

Mouse embryonic stem cell could show an substitutional materials of cells of neuron differentiation, positively increasing their effectiveness in the treatment of nervous symptom. We examined that mouse embryonic stem cells (mESCs) can be induced to undergo neuronal differentiation. After neuronal induction, the phenotype of mESCs changed towards neuronal morphology and mESCs were injected into the lateral ventricle of the experimental animal brain. Transplanted cells migrated to various parts of the brain and ischemic brain injury by middle cerebral artery occlusion (MCAO) increased their migration to the injured cortex. Intracerebral grafting of mESCs mostly improve sensory and motor nervous system of neurological injury in focal cerebral rats.

We propose a smart human-computer interface replacing conventional mouse interface. The interface is able to control cursor and command action with only hand performing without object. Four finger motions(left click, right click, hold, drag) for command action are enough to express all mouse function. Also we materialize cursor movement control using image processing. The measure what we use for inference is entropy of EMG signal, gaussian modeling and maximum likelihood estimation. In image processing for cursor control, we use color recognition to get the center point of finger tip from marker, and map the point onto cursor. Accuracy of finger movement inference is over 95% and cursor control works naturally without delay. we materialize whole system to check its performance and utility.

Diabetic nephropathy is a major and representative complication of type 2 diabetes. Hyperglycemia increases the incidence of diabetic nephropathy, and induces kidney inflammation, thereby causing renal fibrosis, which is an important factor in the pathogenesis of diabetic nephropathy. This study investigated the effects of blackcurrant extract (BLC), which has been implicated in diabetic nephropathy in db/db mice, on glomerular fibrosis and renal dysfunction. The results showed that BLC consumption in type 2 diabetic db/db mice ameliorated diabetes-related metabolic disorders, such as insulin resistance and renal dysfunction, and significantly attenuated renal inflammation and renal fibrosis in diabetic nephropathy. In conclusion, these findings suggest that BLC consumption may help prevent renal fibrosis, inflammation, and consequent diabetic nephropathy.

PDAs와 같은 휴대용 컴퓨터의 발전은 펜을 이용한 데이터 입력과 처리 기술에 대한 요구를 증가시키고 있다. 하지만 대부분의 PDAs용 애플리케이션들은 키보드와 마우스를 주된 입력 도구로 사용하는 데스크 탑 컴퓨터의 GUI와 입력 방식을 그대로 사용하고 있다. 본 논문에서는 펜 기반의 휴대용 컴퓨터에서 필기체 데이터 문서를 편집할 수 있도록 해주는 펜 제스쳐(pen gesture)기능 허용 텍스트 에디터를 개발하였다. 삽입, 삭제, 앞뒤 낱말 바꾸기, 줄 바꾸기 등의 제스쳐 인식 방법과 제스쳐 처리를 위해 스트록들(strokes)을 GCs(Gesture Components) 단위로 그룹화하기 위한 방법들을 제안하였다. 제스쳐 허용 에디터의 개발은 펜 기능만으로 문서 편집을 위한 모든 작업을 가능하게 해 줌으로 사용자의 편의를 극대화시켜 준다.

네트웍 모델러(Network Modeler)는 EMS 시스템에서 전력 네크워크 토폴로지(Network Topology)를 입력하기 위한 도구이다. 네트워크 모델러는 토폴로지 정보를 입력하여 모델을 생성하고 변경하는 일과 네트워크 다이어그램을 생성하는 일 등을 처리한다. 모델을 생성하기 위해 계통요소를 나타내는 심벌을 마우스로 움직여 화면에 배치하고 각 요소의 파라미터를 설정하며 작성된 전력계통 구성이 올바른지 검사하는 기능도 수행한다. 네트워크 모델러는 주로 EMS에서 사용되었고 SCADA 시스템에서는 사용되지 않았으나, 최근 개발되고 있는 SCADA 시스템은 네트워크 모델러를 함께 포함하여 시스템의 기능을 향상시키고 있다. 그러나 기존의 Network Modeler가 EMS 시스템 개발 벤더에 따라 다른 데이터 구조를 가지고 있어서 데이터의 상호 운용성이 떨어지고, 입력방법에 있어서도 자동화 및 자료 연계가 미흡하여 관리에 많은 시간이 소요되는 단점을 가지고 있다. 본 논문에서는 CIM 기반으로 정의된 데이터 모델을 사용자가 그래픽 다이어그램을 이용하여 쉽게 네트워크 토폴로지를 정의하도록 하고, 입력정보의 상호 운영성이 향상된 CIM 기반 Network Modeler를 설계한 내용을 설명하도록 한다.
