There are various kinds of patterns on Li brocade textile of Hainan province in China. Those patterns are rich and colorful. Li (黎族) traditional brocade is an ancient exquisite craftsmanship and a world cultural heritage. This study analyzed and categorized Li brocade pattern of traditional Chinese textiles. Li (黎族) traditional brocade is an ancient exquisite craftsmanship. Based on the research of classifications of Li brocade patterns, expound the application of women's costume. The patterns of Li brocade textile of Hainan province analyzed through three levels: design transforming, meaning prolongation, and refining spirit. The patterns were explored the feasibility way to inherit the patterns of Li brocade for the modern fashion product design. The results showed that Li brocade textile pattern of Hainan province were images sourced from local environment and geographical terrain. They contained the nation's history memory, religion, hope for life of the Li nationality. Those patterns can be categorized as human figure pattern, animal pattern, geometric pattern, appliance or architecture pattern, and Chinese character pattern.

As we know, gigabit ethernet is a new technology to be substituted for current fast ethernet used widely in local area network. The switch used in gigabit ethernet should deal with frames in giga-bps. To do such a fast switching, we need that serveral processes meet the budgets, such as MAC address table lookup, several giga speed path setup, fast scheduling, and etc. Especially MAC address table lookup has to be processed in the same speed with speed of incoming packets, thus the bottleneck in the process can cause packet loss by the overflow in the input buffer. We devise new practical hardware hashing method to perform fast table lookup by minimizing the number of external memory access and accelerating with hardware.

The Rough transform (HT) is often used for extracting global features in binary images, for example curve and line segments, from local features such as single pixels. The HT is useful due to its insensitivity to missing edge points and occlusions, and robustness in noisy images. However, it possesses some disadvantages, such as time and memory consumption due to the number of input data and the selection of an optimal and efficient resolution of the accumulator space can be difficult. Another problem of the HT is in the difficulty of peak detection due to the discrete nature of the image space and the round off in estimation. In order to resolve the problem mentioned above, a possibilistic C-means approach to clustering [1] is used to cluster neighboring peaks. Several experimental results are given.

본 논문은 주전산기 IV로 개발된 SPAX에서 사용할 수 있는 성능 감시기의 설계와구현에 대해 기술한다. SPAX는 지역 메모리를 갖는 노드들이 내부 네트워크에 연결되고, 노드들이 클러스터를 구성하는 계층적인 구조를 이루고 있다. 따라서, SPAX에서 효과적인 성능 감시를 하기 위해서는 SPAX의 구조적 특징을 반영한 새로운 성능 감시기가 필요하게 되었다. 구현된 성능 감시기는 SPAX의 노드, 클러스터, 그리고 전체 시스템 상태를 감시할 수 있도록 설계되었다.

Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology.

We propose in this article a procedure for testing unit and fractional orders of integration, with the roots simultaneously occurring in the trend, the seasonal and the cyclical component of the time series. The tests have standard null and local limit distributions. However, finite sample critical values are computed, and several Monte Carlo experiments conducted across the paper show that the rejection frequencies against unit (and fractional) orders of integration are relatively high in all cases. The tests are applied to the UK consumption and income series, the results showing the importance of the roots corresponding to the trend and the seasonal components and, though the unit roots are found to be fairly suitable models, we show that fractional processes (including one for the cyclical component) may also be plausible alternatives in some cases.

A multistage hierarchical clustering technique, which is an unsupervised technique, was suggested in this paper for classifying large remotely-sensed imagery. The multistage algorithm consists of two stages. The local segmentor of the first stage performs regiongrowing segmentation by employing the hierarchical clustering procedure of CN-chain with the restriction that pixels in a cluster must be spatially contiguous. This stage uses a sliding window strategy with boundary blocking to alleviate a computational problem in computer memory for an enormous data. The global segmentor of the second stage has not spatial constraints for merging to classify the segments resulting from the previous stage. The experimental results show that the new approach proposed in this study efficiently performs the segmentation for the images of very large size and an extensive number of bands

In this paper we implemented the fast thinning unit by modifying the pipeline architecture which was proposed by Stanley R. Sternberg. The unit is useful in preprocessing such as image representation and pattern recognition etc. This unit is composed of interface part, local memory part, address generation part, thinning processing part and control part. In thinning processing part, we shortened the thinning part which performed by means of look up table using window mapping table. Thus we improved the weakness of SAP, in which the number of delay pipeline and window pipeline are equal to image column size. Two independent memorys using tri-state buffer enable the two direction flow of address generated by address generation part. This unit avoids the complexity of architecture and has flexibility of image size by means of simple modification of logic bits.

Architectural design works are proceeded by the collaboration of experts working in many fields, but the traditional method of collaboration, so to speak offline collaboration, has limitation on time and space. The meeting agenda is not well organized in the meeting. Often there are so many items to discuss, that some get left out, and remain unaddressed. The knowledge relying on people's memory is not always accurate. To solve the above problems, we would like to suggest web-based collaboration system in architectural design and provide contents which are called checklists and knowledge database for collaboration.

The control of the data retention time is a main issue for realizing future high density dynamic random access memory. In this paper, we propose the new implantation scheme by gate-related ion beam shadowing effect and buffer-enhanced $\Delta$ Rp increase using buffered N- implantation with tilt and 4X-rotation that is designed on the basis of the local-field-enhancement model of the tail component. We report an excellent tail improvement of the retention time distribution attributed to the reduction of electric field across the cell junction due to the redistribution of N- concentration which is intentionally caused by Ion Beam Shadowing and Buffering Effect using tilt implantation with 4X-rotation.
