The pursuit of efficiency is taken for granted in today's public administration, and the limit of this study exists in the point that we should carefully deal with combining the redundancy scheme to the public administration. Accordingly, although this study should suggest the specific plans and backgrounds of the needs for the redundancy, it will only find out the applicability of the redundancy to the public administration for its purpose. Redundancy means the excess or superfluity in something, which means the surplusage status ranging from the wasteful and excessive supplies, insignificant additions, to the surplusage in a legal pleading. The emphasis of this study is placed on the changes in the rigidity in believing that the removal of the redundancy from the public administration is the best option in any case of the efficiency. In addition, the necessity of the overlapped organization should not be neglected by the concept of the efficiency. Indeed, it is necessary to correct the overlapped function of superfluity and ambiguity public administration, in order to remove the neglect conflicts between the organizations, to guarantee the inconsistency in the public administration and to ensure the efficiency in the public administration volunteering.

The purpose of this study making clear the range of overlapping affairs since many parts of cooker's & dietitian duties are overlapped in the Law of Hygiene & its over-ranked laws. The fact that there're overlapped parts in the different qualifying system endowed by the government may lead too many troubles between cooker's & dietitian who have their own qualification, so it's important to grasp correctly job specifications of cooker's & dietitian and to make clear the sphere of business. This studies present following affairs as cooker's duties through analysis. 1. Participation in the overall Management & Policy department. 2. Making the Menu & Standard recipe. 3. Purchasing, Inspection, Market research on Food materials. 4. Sanitary management. 5. Facility manage & Safety Management. 6. Research & Development on cooking Know-How. 7, Teaching for the members of department. 8. Supervision & business appraisal of cooking members. 9. Sales management & Cost control. 10. Utensil management & its Maintenance.

3차원 그래픽 가속기는 기하학 처리(Geometry processing) 단계와 래스터라이제이션(rasterization) 단계로 구성되어 있다. 기존의 기하학 처리 방식에서는 꼭지점의 좌표계산과 빛의 효과를 계산하는 일련의 단계들이 순차적으로 수행되었는데 이는 많은 양의 폴리곤 처리가 요구되는 현재의 어플리케이션 환경에서 상당한 오버헤드로 작용한다. 본 연구에서는 기하학 처리 파이프라인을 보다 고속으로 처리하기 위해 라이팅 단계를 다른 단계들과 병렬적으로 수행할 수 있는 구조를 제안한다. 실험결과 제안하는 중첩 라이팅 방식의 기하학 처리기(Overlapped lighting geometry processor, OLGP)는 기존의 순차적인 기하학 처리기(Sequential geometry processor, SeqGp)에 비해 최대 21%의 수행 성능 향상을 보였다.

The flow regulators we widely use have some disadvantages. They have a constant flow within each regulator and an inaccuracy with extruding capillary. In this study, we have developed a new type of regulator which was made up of two different capillary tubes overlapped each other. The developed regulator can vary and control the amount of flow. The design parameters of the developed regulator are obtained by using the analytical software. We have proved that the developed regulator can control flow properly through making a trial product and experiment.

In this paper, we propose a fault-tolerant scheduling scheme with energy efficiency for real-time periodic tasks on DVFS-enabled multicore processors. The scheme provides the tolerance of a permanent fault with the primary-backup task model. Also the scheme reduces the energy consumption of real-time tasks with the fully overlapped execution between each primary task and its backup task, whereas most of previous methods tried to minimize the overlapped execution between the two tasks. In order to the leakage energy loss of idle cores, the scheme activates a part of available cores with rarely used cores powered off. Evaluation results show that the proposed scheme saves up to 82% energy consumption of the previous method.

In this paper, we propose a non-overlapping volume decomposition method that decomposes a solid model into non-overlapped volumes. The non-overlapping volume decomposition finds non-overlapped volumes from maximum volumes. After introducing the concept of the non-overlapping volume decomposition, we discuss technical issues and solutions for them. The non-overlapping volume decomposition is verified by the experiments with a prototype system. From the experiments, it was found that the non-overlapping volume decomposition shows better result than maximum volume decomposition from the view point of design feature recognition.

Modulated components of a speech signal are frequently used for speech coding, speech recognition, and speech synthesis. Time-frequency representation (TFR) reveals some information about instantaneous frequency, instantaneous bandwidth and boundary of each component of the considering speech signal. In many cases, the extraction of AM-FM components corresponding to instantaneous frequencies is difficult since the Fourier spectra of the components with time-varying instantaneous frequency are overlapped each other in Fourier frequency domain. In this paper, an efficient method decomposing speech signal into AM-FM components is proposed. A variable bandwidth filter is developed for the decomposition of speech signals with time-varying instantaneous frequencies. The variable bandwidth filter can extract AM-FM components of a speech signal whose TFRs are not overlapped in timefrequency domain. Also, amplitude and instantaneous frequency of the decomposed components are estimated by using Hilbert transform.

In this paper, we propose an automatic method which combines two or more images acquired by camera on the air-vehicle into a larger image mosaics. The shift, scaling, rotation factors between two images can be calculated by using the correspondences between the points of the images. In order to estimate these factors, we find the relative positions of two images with respect to each other by using the SIFT descriptor and the RANSAC algorithm. After estimating the factors, the images can be merged into a single image mosaic by warping the target image. To avoid seams when mosaics are constructed from overlapped images, we apply the average gray level value of points within a overlapped zone. We have tested our proposed method on various image sets and have confirmed that our method produced good result subjectively.

본 논문에서는 AC-PDP내에서 고화질의 영상을 표현하고자한다. PDP구동방법중의 하나인 ADS방식을 보면 Reset, Address, Sustain의 세부분으로 나뉜다. 이 같은 ADS구동에 있어서 각 구간마다 제안된 시간을 이용한다. Reset구간에서는 각각의 Call을 균일하게 하고, Address구간에서는 Call의 On/off를 결정한다. Sustain구간 선택된 셀을 나타낸다. 이 같은 ADS방식에서 Addressing방법에서 Line-by-Line Scanning을 방법을 이용한다. 라인을 순차적으로 스캔함으로써 시간이 일정해진다. 라인의 순서를 홀수라인과 짝수라인으로 구분하여 각각의 라인에서 생기는 준비기간 동안 시간을 중복으로 사용함으로서 어드레싱시간을 감소시킬 수 있다 이를 구현하기 위해서 interlaced Line-by-Line Scanning을 이용한다.

In this paper, we propose a modified overlapped block-based motion estimation(MOBME) algorithm for a frame rate up conversion. The proposed method performs motion estimation based on the OBME and FSME. The proposed method shows better performance in estimating the true motion than the conventional method.
