  • A genetic algorithm to determine the optimal signal sequence and double cycle pattern is described. The signal sequence and double cycle pattern are used as the input for TRANSYT to find optimal signal timing at each junction in the area traffic networks, In the genetic process, the partially matched crossover and simple crossover operators are used for evolution of signal sequence and double cycle pattern respectively. A special conversion algorithm is devised to convert the signal sequence into the link-stage assignment for TRANSYT. Results from tests using data from an area traffic network in Leicester region R are given.

  • Objective : This study was to compare antioxidant activity and HPLC pattern analysis from 4 species of changpo(ch$\={a}$ngp$\'{u}$). Methods : To compare the antioxidant activity and HPLC pattern analysis from the 4 species of changpo, we performed the in vitro anti-oxidative activity assays and HPLC analysis from 70% ethanol extracts of Acorus gramineus Sol. (=AG), A. tatarinowii Schott (=AT), A. calamus L. (=AC) and Anemone altaica Fisch. ex C.A.Mey (=AA) taken in the herbal medicine market of Korea. Results : AG has the most effective anti-oxidative activity among 4 species of changpo. As the HPLC pattern analysis, AT was detected the unknown peak at retention time 14.9 min whereas AG was not showed any peak at the same retention time. These results suggest that AG could be used rather than AT when it need to be prescribed as anti-oxidative medicine. Conclusions : This result can be used as the basic data contributing to the stability of AG according to an appropriate clinical application.

  • This paper proposes an improved vascular pattern extraction algorithm for person verification applications. The proposed direction-based vascular pattern extraction (DBVPE) algorithm is based on the directional information of vascular patterns. It applies two different filters to the input images: row vascular pattern extraction filter (RVPEF) for effective extraction of the abscissa vascular patterns and column vascular pattern extraction filter (CVPEF) for effective extraction of the ordinate vascular patterns. We use the combined output of both filters to obtain the final hand vascular patterns. Unlike the conventional hand vascular pattern extraction algorithm, the directional extraction approach prevents loss of the vascular pattern connectivity. To validate the DBVPE algorithm, we used a prototype system with a DSP processor. The prototype system shows approximately a three-times better false acceptance rate (FAR) than the conventional single filter algorithm.

  • Sequential pattern mining has become an essential task with broad applications. Most sequential pattern mining algorithms use a minimum support threshold to prune the combinatorial search space. This strategy provides basic pruning; however, it cannot mine correlated sequential patterns with similar support and/or weight levels. If the minimum support is low, many spurious patterns having items with different support levels are found; if the minimum support is high, meaningful sequential patterns with low support levels may be missed. We present a new algorithm, weighted interesting sequential (WIS) pattern mining based on a pattern growth method in which new measures, sequential s-confidence and w-confidence, are suggested. Using these measures, weighted interesting sequential patterns with similar levels of support and/or weight are mined. The WIS algorithm gives a balance between the measures of support and weight, and considers correlation between items within sequential patterns. A performance analysis shows that WIS is efficient and scalable in weighted sequential pattern mining.

  • The various software engineering techniques have been appeared in order to cope with the software crisis since 1980's. Currently, the research against the techniques likes the Design pattern, Component which improve the software's re-use are spread out. Also S/W Development Process are interested intensively which attempts the quality and a increasing productivity of software development with the basic policy. The design pattern is the solution against the problem which occurs repeat in a specific area. Many design pattern are developed and researched, but the method which accommodates the developed design pattern efficiently in the phase of analysis and design software development process is not good enough, so it is the actual applying technique is difficult. In this paper we suggest and the “UML components+” which is a efficient component development process from customizing EJB based the J2EE using the “UML Components” which is a component development methodology. Applying J2EE pattern efficiently with UML components+, there is a possibility of efficiency in the component development based pattern.

  • The purpose of this study was to develop the jacket pattern drafting method for Korean middle-aged women. The study was composed as follows : 1. Body measurement and statistical analysis : Two hundreds and forty four middle-aged women between the ages of forty five and fifty nine were measured on 52 items. 2. Development of new jacket pattern drafting method : Measurement items necessary to draft new jacket pattern were back waist length, bust girth, waist girth, hip girth, back interscye breadth, front interscye breadth, neck base girth, nipple length, nipple to nipple breadth, 1/2 posterior shoulder length and sleeve length. Basic jackets constructed from the experimental patterns were examined through the fitting test. 3. Evaluation of the new pattern drafting method : The sensory evaluations for appearance and comfort were applied to evaluate the new jacket pattern by comparing it with one of the conventional jacket patterns (Lee Hyung-Suk's). According to the result of sensory evaluation, the new jacket pattern was more positive.

  • The aim of this study was to suggest appropriate factors for production pattern making of women's clothing. Sample pattern designers and production patterners of 13 women's brands were individually interviewed about pattern making process and factors necessary. The results were as follows: The factors to be considered in pattern making were categorized in three groups. 1. Factors to be considered to achieve the correct use of specific materials: elasticity, shrinkage, lining and interlining 2. Factors to be considered to satisfy the design specifications: silhouette, dart distribution, collar and sleeve, trimming 3. Factors to be considered for better sewing quality: skillfulness of the sewer, sewing methods and sewing equipment. 4. Suggestions were made for appropriate factors. A focus-group-interview in pattern design has been interviewed to verify the suggested factors. The factors were presented as a guide to develop the production pattern. 5. For better usage of the factors, standardization were suggested for making process with necessary factors for jacket, skirt.

  • Pants is an item of clothes of which physical suitability for improvement of appearance and movement is greatly emphasized. The pattern design of pants is very important because the fitness of crotch region, which is difficult to measure, is structurally essential in pants. This study gives detailed pattern development data for the future pattern design by considering design factors related with crotch region of pants and by suggesting related data. For this study, we measured and analyzed the measuring size of each parts of pattern and the design methods related with crotch region selecting 20 textbooks used in universities and institutes of higher education. Through this study, crotch region of pants pattern related design data were obtained and this result could be a primary information in development and education of pants pattern.
