Due to the development of IT technologies and the Internet penetration, the importance of Web accessibility has greatly increased and accordingly been studied a lot. This study noticed that the current evaluation algorithm for "Table Elements," which are used for data and layout tables, has many problems. Based on the Web Accessibility Guidelines, this study presents an improved evaluation algorithm for "Table Elements" and verifies its validity.

Table detection is a challenging problem and plays an important role in document layout analysis. In this paper, we propose an effective method to identify the table region from document images. First, the regions of interest (ROIs) are recognized as the table candidates. In each ROI, we locate text components and extract text blocks. After that, we check all text blocks to determine if they are arranged horizontally or vertically and compare the height of each text block with the average height. If the text blocks satisfy a series of rules, the ROI is regarded as a table. Experiments on the ICDAR 2013 dataset show that the results obtained are very encouraging. This proves the effectiveness and superiority of our proposed method.

Topology optimization is begun with layout optimization that is attributed to Rozvany and Prager of the 1960's. They claimed that structure was transformed into truss connecting all the nodes of finite element and optimized by control of its sectional modulus. But, this method is partial topology optimization. General layout optimal design appliable to continum structure was proposed by Bendsoe and Kikuchi in 1988. Topology optimization expresses material stiffness of structure into function of arbitrary variable. If this variable is 1, material exists but if this variable is 0, material doesn't exist. Therefore, topology optimization searches the distribution function of material stiffness for structure. There are a few researchs for simple engineering problem such as topology optimization of square plane structure or truss structure. So, This study applied to topology optimization of table liner for vertical roller mill that is the largest scale in the world. After table liner decreased by 20% of original weight, the structure analysis for first optimized model was performed.

In case of VLSI design, the shuffle-exchange graph is useful for optimal layout. HOEY and LEISERSON proposed the method of drawing a N-nodes shuffle-exchange graph on O(N2/log N) layout area by using the complex plane digram. [2] In this paper, a new algorithm for drawing the shuffle-exchange graph is proposed. This algorithm is not by using the complex plane diabram, but the table of e decimal represented nodes of shuffle-edge relations. And the structural properties for optimal layout of the graph are summarized and verified. By using this more simplified algorithm, a FORTRAN program which can be treated faster is written. Aimed near optimal shuffle-exchange graphs are printed out by giving inputs` the number of nodes.

< TABLE > tags in HTML documents are widely used for formatting layout of Web documents as well as for describing genuine tables with relational information. As a prerequisite for information extraction from the Web, this paper presents an efficient method for sophisticated table detection. The proposed method consists of two phases: preprocessing and attribute-value relations extraction. For the preprocessing where genuine or ungenuine tables are filtered out, appropriate rules are devised based on a careful examination of general characteristics of < TABLE > tags. The remaining is detected at the attribute-value relations extraction phase. Specifically, a value area is extracted and checked out whether there is a syntactic coherency Futhermore, the method looks for a semantic coherency between an attribute area and a value area of a table that may be inappropriate for the syntactic coherency checkup. Experimental results with 11,477 < TABLE > tags from 1,393 HTML documents show at the method has performed better compared with previous works, resulting in a precision of 97.54% and a recall of 99.22% in average.

Document image is segmented and classified into text, picture, or table by a document layout analysis, and the words in table regions are significant for keyword spotting because they are more meaningful than the words in other regions. This paper proposes a method to extract words from table regions in document images. As word extraction from table regions is practically regarded extracting words from cell regions composing the table, it is necessary to extract the cell correctly. In the cell extraction module, table frame is extracted first by analyzing connected components, and then the intersection points are extracted from the table frame. We modify the false intersections using the correlation between the neighboring intersections, and extract the cells using the information of intersections. Text regions in the individual cells are located by using the connected components information that was obtained during the cell extraction module, and they are segmented into text lines by using projection profiles. Finally we divide the segmented lines into words using gap clustering and special symbol detection. The experiment performed on In table images that are extracted from Korean documents, and shows $99.16\%$ accuracy of word extraction.

The structure of conventional CAM(Content Addressable Memory) cell, used to Look-up table scheme in Huffman CODEC, is not performed by being separated in reading, writing and match operation. So, there is disadvantages that the control is complicated, and the floating states of match line force wrong operation to be happened in reading, writing operation. In this paper, in order to improve the disadvantages and proces the data fast, fast Look-up table is designed using DBLCAM(Dual Bit Line CAM)-performing the reading, writing operation and match operation independently and Two-port SRAM being more fast than RAM in an access speed. Look-up table scheme in Huffman CODEC, using DBLCAM and Two-port SRAM proposed in this paper, is designed in Cadence tool, and layout is performed in 0.6${\mu}{\textrm}{m}$ 2-poly 3-metal CMOS full custom. And simulation is peformed with Hspice.

The purpose of Container Terminal Facilities Arrangement is efficiently arrangement of each unit logistics parts. Facilities Arrangement is rationally accomplished to be minimize moving time, prevent reverse trip, optimal space utilization, benefit of worker, minimize handling cost. Thus, It is important that expert knowledge and mathmatical analysis method to rationally facilities arrangement. In this paper we framed SLP(Systematic Layout Planning} Procedure and described to the process of application.

The purpose of this study was to identify and categorize the space use characteristics of the university professor's office. The data were recorded and collected through the physical trace method. Acture Measurement. Photograph, sketch and CAD drawings were used to trace 118 professors offices at Yonse-University. The analysed features were the user characteristics, the size, characteristics of space (such as composition, layout and furniture arrangement), the appliance and the instrument characteristics. To categorize the 'space use' characteristics. 6 variables were used: 1) the territorial characteristics, 2) the spatial relationship between professor's territory and entrance, 3) the layout type of work area, 4) the spatial relationship between professor's and assistant's work area, 5) the arrangement of table, and 6) the completion of sofa set. The results of this study are expected to be used as a basis for the development of design alternatives for the most typical university professors' office.

This study was surveyed to investigate the condition and satisfaction of foodservice environment. the survey was conducted based on an instrument which was developed by reviewing previous research. The instrument was provided to 57 nutritionists at the elementary schools in Taegu area, and its contents include the standard and relevance of kitchen center, the layout type and the standard of satisfaction for the cooking equipment, washing machine, kitchen table and kitchen facilities. Data obtained from survey were analyzed by SAS. These results show that the combination layout type among four types of cooking center in the arrangement gives the highest standard of satisfaction to nutritionists. The amounts of equipment holding are related to its arrangement in the standard of satisfaction.
