  • This study aims to explore the present and future of agricultural extension system in Uganda. Though Uganda has used many approaches in its agricultural extension, very little has been registered in farm productivity and profitability. Too many reforms some of them some are top-down while others are bottom - up. In most cases these reforms may not be given a chance to develop to show their impact. Future success of agricultural extension and rural development efforts in Uganda will depend not only on the presence of technical expertise and availability of resources but also on each government's willingness to redefine the role of its institutions and to allow the active participation of rural people in formulating and implementing and agricultural extension and rural development programs. As result the public extension systems in Uganda needs to be demand-driven so to make it relevant and important to the beneficiary.

  • Top-down approach in the intelligent robot research has focused on the single object intelligence however, it has two weaknesses. One is that has a high cost and a long spending time of sensing, calculating and communications. The other is the difficulty of responding to react changes in the unpredictable environment. we propose the collective intelligence algorithm based on Bottom-up approach for improving these weaknesses and the applied agent model and verify by simulation. The Modified Flocking Algorithm proposed in this research is the algorithm which is modified version of the concept of the Flocking (Craig Reynolds) which is used to model the flocks, herds, and schools in the graphics or games, and simplified the operation of conventional Flocking algorithm to make it easy to apply for the number of group robots. We modeled the Boid agent and verified possibility collectivization of the Modified Flocking Algorithm by simulation. And We validated by the actual multiple mobile robot experiment.

  • Spatial neglect is a neurological disorder following stroke, a lesion that usually affects the right hemisphere, fail to process or attention on the contralateral side of body and space. Functional neuroimaging studies report that spatial neglect is associated with lesions of large middle cerebral artery, perisylvian network and attention network. Spatial neglect is associated with a poor outcome. For optimal diagnosis and intervention, Types and theories of spatial neglect should be considered, in addition to clinical assessment with the conventional test and functional test. The treatment for spatial neglect could be consist of top-down approaches and bottom-up approaches. Recent trends in rehabilitation intervention for spatial neglect have reported prism adaptation.

  • Introduction : Sensory Integration(SI) theory, science it is developed by an occupational therapist A. Jean Ayres, is the one of the most popular frames of reference used in occupational therapy(OT) intervention. It has been proved as a scientific theory especially in neuroscience discipline through abundant research and practice. Occupational therapists apply the SI therapy with strong clinical reasoning to improve adaptive behaviors of their clients and try to link the adaptive behaviors with occupational performance in the clients' everyday life. One of the manners regarding clinical reasoning is Top-down approach. In occupational therapy discipline, Top-down approach is well-reflected within two evaluation tools; Canadian Occupational Performance Measure(COPM) and Assessment of Motor and Process Skills(AMPS) and two models of practice; Canadian Model of Occupational Performance(CMOP) and Occupational therapy intervention process model(OTIPM). Objective : The purpose of this paper demonstrates how SI therapy can be employed within OTIPM and how the OT process (evaluation-intervention-outcome) can be structuralized based on the Top-down approach. This single-case study recognizes the impact of a SI therapy for a male adolescent on his occupational performance. Intervention Examined : "P" was 16 years old male adolescent with no diagnosis and junior of the high school when he was referred. P was always with mouth opened, showed difficulties in gathering things need to be prepared and managing and paying money for shopping, and his colleges dislike getting close to him because he can't was his body well. AMPS was administrated in initial evaluation and reevaluation of P's occupation performance, Bruininks-Oserestky Test of Motor Proficiency-2(BOT-2) was carried out to assess motor functions and perception skills related in sensory integration, and occupational therapist performed clinical observation in order to complement the evaluation quantitatively and quantitatively. Based on the evaluation, it is concluded that the SI therapy is primary means to improve P's occupational performance, and three therapeutic approaches were constructed; restorative, acquired and compensatory approach. P showed improved motor and process skills in occupational performance after undergone the occupational therapy. Conclusions : The sensory integration therapy was practical enough to build the bridge between the occupational performance(Top) and the underlying component problems (Bottom). The OTIPM was helpful to identify meaningful occupation for P and P's family within P's contexts, and the AMPS was valuable to analyze and clarify the cause of difficulties in the chosen occupational performance.

  • This paper proposes to use an algorithmic debugging technique for locating logical errors in Java programs. The algorithmic debugging is a semi-automated debugging technique that builds an execution tree from a source program and locates logical errors, if any, included in the program from the execution tree with top-down method. So, it is very important to build a suitable execution tree from the various programming languages. In this paper we propose the method for building an execution tree iron Java programs and walk through an example. This approach could reduce the number of interactions between a user and a debugging system than the traditional step-wise debugging technique.

  • 본 연재는 앞으로 2회에 걸쳐 '네덜란드의 건축정책(Architectural Policy)'과 '네덜란드의 건축센터(Architecture Centers)'의 역할을 살펴보게 될 것이다. 이를 통해 각각 중앙 정부와 지역이 어떻게 상호 관계를 맺으며 네덜란드의 건축과 도시를 조율하고 발전시켜나가는 건축 정책의 중요한 주체로서 작용하는지 살펴보고자 한다. 이러한 복합적인 층위의 역할과 그 협력 관계를 이해하는 것은 오늘날 세계 건축계를 이끌어 가고 있는 네덜란드의 건축문화를 이루는 원동력이 무엇인지를 아는 데에 있어 매우 중요한 일이다. 네덜란드는 세계 최초의 정부 주도로 수립된 건축정책을 통해 지난 20여 년 간 건축의 공공성을 표방하며 자국의 건축문화를 발전시켜왔다. 네덜란드의 건축문화는 개별적인 작가들에 의해서라기보다는 건축가(군), 건축기관, 정부 등 여러 주체들에 의해 발전되었으며 건축 정책을 통해 지속적인 시스템을 구축했다는 점을 주목해야 한다. 네덜란드 정부는 건축정책을 수립하고 그 실행을 전문적 건축기관에 일임함으로써 전문가들이 분야의 전문성과 폭넓은 네트워크를 바탕으로 건축의 공공성을 지향하고 건축실천의 방향성을 유도하는 역할을 하고 있다. 한편 지역의 자발적인 움직임으로 설립, 운영되는 지역 건축센터들은 지역의 폭넓은 커뮤니티에의 접근성을 바탕으로 정부의 적극적인 지원 속에서 중앙의 건축정책의 방향성을 지역의 커뮤니티에 전달하고 지역의 이슈를 발굴하고 발전시킨다. 본 연재는 시대적 변화 속에서 개별적 주체들의 의식 성장으로 하향식 주도가 더 이상 작동하기 힘들며 관심과 동기가 다른 다양한 주체들과의 협의와 협력이 불가피해지고 공공성의 대변자 역할을 했던 건축, 도시계획의 위상이 근본적으로 변화를 겪으면서 공공성에 대한 이해의 재정립이 요구되는 현 시대에 네덜란드의 건축정책과 건축센터의 사례를 통해 우리에게 시사하는 바를 찾고자 한다.

  • 본 연구의 목적은 비디오/오디오 프로토콜 분석 방식을 이용해서 텍스타일 디자인 프로세스 중 모티브 개발 단계에서 디지털 나염(DTP : Digital Textile Printing) 전용 캐드(CAD)와 같은 디자인 저작도구를 설계할 때 어떤 요소에 중점을 두고 개발 할 것인지에 대한 향상된 지침을 마련하는데 있다. 텍스타일 디자인 프로세스에 대한 프로토콜 분석을 위해 선행 연구를 고찰하여 디자인 행동 범주의 틀을 하향식(top-down)방식으로 설정하고 실제 행동 프로토콜 (action protocol) 분석을 통해 상향식(bottom-up)방식으로 세부 디자인 행동을 도출하였다. 텍스타일 디자인은 선행연구의 건축디자인과는 다른 특징을 지니기 때문에 프로토콜 분석에서도 새로운 디자인 행동 범주(action category)가 필요하게 되었다. 이를 위하여 모델 휴먼 프로세서(Model Human Processor)이론을 근거로 디자인 행동을 모터 행동(motor action), 지각 행동(perceptual action), 인지 행동(cognitive action)의 세 가지 범주[4]로 나누었으며 텍스타일 디자인 프로세스에 적합한 코딩 스킴(coding scheme)을 개발하였다. 본 연구에서는 이 새로운 코딩 스킴을 토대로 디자인 저작도구에 대한 디자이너의 인지적 모형(Cognitive Model)을 개발하였다. 이렇게 개발된 디자이너의 인지적 모형은 디지털 나염을 기반으로 하는 모티브 개발 단계에서 스케치와 렌더링에 대한 디자인 저작 도구의 향상된 설계지침 뿐만 아니라 방향도 시사하였다.

  • The distance join is a spatial join which finds data pairs in the order of distance between two spatial data sets using R-trees. The distance join stores node pairs in a priority queue, which are retrieved while traversing R-trees in a top-town manner, in the order of distance. This paper first shows that a priority strategy for the tied pairs in the priority queue during distance join processing has much effect on its performance, and then proposes an optimized secondary priority method. The experiments show that the proposed method is always better than the other methods in the performance perspectives.

  • This paper deals with a new design methodology for a switching-type fuzzy-model-based controller in continuous and discrete-time system. Takagi-Sugeno (TS) fuzzy model is employed to design the switching-type fuzzy-model-based controller. A switching-type fuzzy-model-based controller is constructed based on the spirit of “divide and conquer”. The global system which has several rules in divided into several subsystems and then, a solution is found at each subsystem. The global solution is determined by a conjunction of the solutions of each subsystem. The design conditions are formulated in terns of linear matrix inequalities (LMIs), which guarantee the stabilization of a given TS fuzzy system. Simulation examples are included for ensuring the proposed control method.
