The evaluation of food taste is one of the important activities of human consciousness and it is practiced by sensory analysis using 5 terminal sensorial consciousness among many other functions. These consciousness activities may be conducted by 3 way branching transformation (3-WBT) logic, which choose one out of 3 options under the multi-layered consciousness decision making system. On the basis of this logic, cognitive sensory evaluation (CSE) method was developed to carry out questionnaire survey covering objective and subjective issues during consumption of food for pregnant women. The results of the CSE for several food items was presented with the Table-pattern called CSET covering consciousness factors and their effects on the food consumers.

This study developed a practical knitwear design with applying the pattern of Queen Yeong's pearl pouch. The ume flower pattern of pearl pouch was simplified to be one repeat pattern, and four simulated knit pattern samples of G-A, G-B, R-A, and R-Bwere made with cable, cross, and two background colors of gray and red using Texpro V.11.0. The items of design application were selected after an interview with a panel of university students in their twenties and knit samples were produced by hand knitting. The small sized G-A for the partial ornament of hat, sweater, skirt, kitchenware case and accessories; the long sized G-B for the tuck of sleeves, hem of skirt and one-piece dress, partial ornament of sweater, scarf, and curtain decoration: the small sized R-A was preferred for point ornament of pouch, boots, hat, partial ornament of children's fashion products and accessories: the long sized R-B for table runner, leg warmer, tuck of sleeves, skirt hem, necktie, and scarf. The knit samples were formulated with partial ornaments attached on dress and props or connected each other. Colors of pastel and navy were also presented to meet the demands of panels. The study placed a limit on the slight difference between the simulation samples and knit samples due to the characteristics of threads and hand tension. The color variation for multiple coordination and activation to reduce the piece rate for young customers remains to be discussed in the near future.

The IDS/IPS(Intrusion Detection/Prevention System) has been widely deployed to protect the internal network against internet attacks. Reducing the packet inspection time is one of the most important challenges of improving the performance of the IDS/IPS. Since the IDS/IPS needs to match multiple patterns for the incoming traffic, we may have to apply the multiple pattern matching schemes, some of which use finite automata, while the others use the shift table. In this paper, we first show that the performance of those schemes would degrade with various kinds of pattern sets and payload, and then propose a hybrid multiple pattern matching scheme which combines those two schemes. The proposed scheme is organized to guarantee an appropriate level of performance in any cases. The experimental results using real traffic show that the time required to do multiple pattern matching could be reduced effectively.

In the diverse modern era, individuals are actively striving to develop and demonstrate their capabilities . As a means of cultivating interest in hanbok and differentiatedabilities , there exists a national qualification verification for hanbok technician. This study focuses on using Saekdong-jeogori pattern that is suitable for design and allows for accurate pattern production in a short time for beginners taking the practical test for hanbok technicians. We analyzed five experimental Saekdong-jeogori patterns, from which the final patterns for research were derived through appearance tests on the first table evaluation and the second outfit evaluation. The Saekdong-jeogori pattern-1 for research utilized the body values presented by beginners taking the hanbok technician qualification verification, while the rest were calculated or applied using equivalents. The godae point and armhole depth were calculated based on the chest circumference, and the armhole curve, sleeve shape, doryeon line, and sleeve-end were drawn, regardless of the changes in the figures, using equal parts. The Saekdong-jeogori pattern-2 provided activity by vertically lowering the side line from the end of the armhole, and the keotseop line was drawn by moving 1 cm from the width of the Kit to the armhole line. The seopko was raised 0.2 cm from the keotseop reference line and0.2cm , and was supplemented by its connection to a natural curve.

The FP-tree(Frequency Pattern Tree) mining association rules algorithm was proposed to improve mining performance by reducing DB scan overhead dramatically, and it is recognized that the performance of it is better than that of any other algorithms based on different approaches. But the FP-tree algorithm needs a few more memory because it has to store all transactions including frequent itemsets of the DB. This paper implements a FP-tree algorithm on a general purpose UNK system and compares it with the DHP(Direct Hashing and Pruning) algorithm which uses hash tree and direct hash table from the point of memory usage and execution time. The results show surprisingly that the FP-tree algorithm is poor than the DHP algorithm in some cases even if the system memory is sufficient for the FP-tree. The characteristics of the test data are as follows. The site of DB is look, the number of total items is $1K{\sim}7K$, avenrage length of transactions is $5{\sim}10$, avergage size of maximal frequent itemsets is $2{\sim}12$(these are typical attributes of data for large-scale convenience stores).

Purpose : Hepatic arterial perfusion scintigraphy with Tc-99m-macroggregated albumin (HAPS) study was carried out in 16 patients with hepatocellular carcinoma(HCC) and in six patients without liver tumor to evaluate HAPS findings of hepatocellular carcinoma and usefullness of HAPS. Materials and Methods : HAPS with planar and SPECT study were performed in 22 patients after conventional hepatic or celiac arteriography. For HAPS study, 4-5 mCi of MAA mixed with 2ml of saline was injected into proper hepatic artery or its distal branches at the rate of approximately 1ml/sec. We analysed 21 HCCs over 2cm in diameter(average diameter; 6.4cm) and 17 of 21 HCCs were over 4cm in diameter(Table 1). CT, sonography and angiography were performed within two week in all 16 patients and liver scan was performed in 12 patients. Results : Three different pattern of tumor perfusion were observed in 16 patients with HCC (Table 2). 1) diffuse increased perfusion in 16 of 21(76%)(Fig. 1) 2) increased peripheral perfusion in 4 of 21(19%) (Fig. 2) 3) diffuse decreased perfusion in 1 of 21 (5%) Arteriovenous shunt indicated by lung uptake of MAA were observed in 9 of 16(56%)(Fig. 4). In contrast, angiography demonstrates arteriovenous shunt in 2 of 16(13%). There was no accumulation of radioactivity on RBC-blood pool scan in all six patients with HCC examined (Fig. 1). Conclusion : HAPS is useful study in evaluation of perfusion pattern or vascularity of HCC and in detection of arteriovenous shunt.

The main objective of this research is to examine the spillover effects of technological knowledge from IT industry to other industrial sectors and, based on empirical findings, to draw policy implications and suggest policy directions. To this end, we divide IT industry into IT equipment and IT service, assuming that these two sub-sectors are considerably different each other in terms of technology knowledge flow. Other industries are classified into 17 different sectors based on the KSIC of 1990. As the proxy measure of technological knowledge, the notion of R&D stock is employed. The Input/output(I/O) Table is used to define the inter-industrial flow pattern and to draw the knowledge flow matrix. As the research methodology, cost function model is employed to gauge the spillover effects of technological knowledge of IT industry. Based on the results of analysis, it is found that the economic impact of technology diffusion also exhibits a different pattern between IT equipment and IT service. The diffusion of IT equipment tends to show labor-substitution effect whereas IT service displays labor-creation effect. This fact should be considered in devising industry, education, and labor policy. The expectations from this research are as follows. First, the sectoral pattern, difference between IT equipment and service in particular, identified from this research may shed light on the sector-specific policy direction. It is emphasized that a sector-specific approach, rather than an aggregate approach, is relevant for formulating IT policy. Second, it is expected that the importance of technology diffusion programs and policy measures are recognized among policy makers in IT industry.

Recently, the aspect of consumers' preference for design has been changed to a pattern of respect for personality, based on 'personal value of passion'. The differentiated personal passion of modern people does not allow them to select mass-produced industrial product, and leads them to choose life style different from others. Specially, consumers want to express. their differentiated personality by preferring and possessing the originally designed products. Therefore, the originally designed products that are clearly identifiable become the object of consumers' consideration, and stimulate the consumers' desire to purchase. According to new needs of consumers, it is required to reconsider the old design pattern of furniture based on simplicity and propose new design for furniture to meet the needs of consumers. Mass production has resulted in a strong focus on simplicity rather than difficulty and complexity of the production process. This tendency shows the design pattern that leans toward one side excluding the expression of correlative concept among design elements. This one sided design leads modern people to have no personality, and shows only simple and uniform expression of passion. Therefore, this paper is purposed to develop furniture with more personality by applying correlative concept that has been taken less seriously in the field of design to furniture design.

This paper presents a real-time correction method of the movemont errors of a translatory precision machine axis. This method is a null-balances technique in which two plane mirrors are used to generate an interferometric fringe pattern utilizing the optical principles of TwymanGreen interferometry. One mirror is fixed on a reference frame, while the other is placed on the machine axis being supported by three piezoelectric actuators. From the fringe pattern, one translatory and two rotational error components of the machine axis are simultaneously detected by using CCD camera vision and image processing techniques. These errors are then independently suppressed by activating the peizoelectric actuators by real-time feedback control while the machine axis is moving. Experimental results demonstrate that a machine axis can be controlled with movement errors less than 10 nm in vertical straightness, 0.1 arcsec in pitch, and 0.06 arcsec in roll for 50mm travel by adopting the real-time correction method.
