The purpose of this study was to suggest the standard sizing system and grading rules according to body types of elderly women. The data were the anthropometric measurements of 329 women aged 60 and older measured in 2001. To determine the effective and useful clothing sizing system, the distribution of hip girth and bust girth of 3 body types which were suggested in KS K 0055 was analyzed, and the significant difference among adjoining hip girth ranges was analyzed, too. And the sizes of major body parts that were used for manufacturing clothing were made to have regular interval between each clothing sizes. From this study, we certified that each different sizing system for 3 body types to manufacture more suitable clothing for elderly women was necessary and suggested the standard size for each body type. And we also suggested the patternmaking sizes that were needed to manufacture ready-made clothing. On the basis of standard size, we suggested the grading rules for 3 body types. And we verified the propriety of the grading rules for 3 body types through the fitting test, and we knew that the grading rules for 3 body types of this study was very useful to manufacture clothing for elderly women.

Nowadays, the use of apparel CAD system is important to the mass production of ready to wear. Especially, computer-based grading is the most important process to improve the fitness of clothes and to reduce the time needed to make various size pattern. The purpose of this study was to suggest a standard sizing system for high school boys' pants and to suggest a grading method according to the sizing systems. The subjects were 217 high school boys of 16 to 18 year-old. The size intervals of waist girth and hip girth were 3 cm and 4 cm respectively. The sizing system, which had frequencies more than 4%, was classified 8 cases. Among them, 71-92 and 71-88 size were the most frequent size and were adopted the basic size for the two types of grading. According to the sizing system, hand-made patterns were manufactured. By measure of the each part of the slacks, 4 size's new grading-rule patterns were developed by each size. This result will contribute to clothing fitness of consumer and the amount of production.

A computer vision based automatic intelligent sorting system for dried oak mushrooms has been developed. The developed system was composed of automatic devices for mushroom feeding and handling, two sets of computer vision system for grading , and computer with digital I/O board for PLC interface, and pneumatic actuators for the system control. Considering the efficiency of grading process and the real time on-line system implementation, grading was done sequentially at two consecutive independent stages using the captured image of either side. At the first stage, four grades of high quality categories were determined from the cap surface images and at the second stage 8 grades of medium and low quality categories were determined from the gill side images. The previously developed neuro-net based mushroom grading algorithm which allowed real time on-line processing was implemented and tested. Developed system revealed successful performance of sorting capability of approximate y 5, 000 mushrooms/hr per each line i.e. average 0.75 sec/mushroom with the grading accuracy of more than 88%.

Objectives : This study was to compare the effect of electroacupuncture therapy on peripheral facial paralysis according to the wave forms. Methods : We investigated 56 cases of inpatients with Peripheral Facial Paralysis, and divided them into two groups, One group was treated by electroacupuncture on interrupted wave, and the other was treated by electroacupuncture on dense-dispersed wave. We evaluated the effect of electroacupuncture in each group by using Gross Grading System of House-Brackmann and Yanagihara's Unweighed Grading System. Results : 1. In the interrupted wave and the dense-dispersed wave, compared with baseline, at final, Gross Grading System of House-Brackmann was significantly decreased and Yanagihara's Unweighed Grading System was significantly increased. 2. At final, Interrupted wave showed significant decrease on the Gross Grading System of House-Brackmann and significant increase on Yanagihara's Unweighed Grading System compared with dense-dispersed wave. Conclusions : These results suggested that interrupted wave should be more useful for improving symptoms related with peripheral facial paralysis than dense-dispersed wave.

The extraction of important features in cancer cell image analysis is a key process in grading renal cell carcinoma. In this study, we applied three-dimensional (3D) texture feature extraction methods to cell nuclei images and evaluated the validity of them for computerized cell nuclei grading. Individual images of 2,423 cell nuclei were extracted from 80 renal cell carcinomas (RCCs) using confocal laser scanning microscopy (CLSM). First, we applied the 3D texture mapping method to render the volume of entire tissue sections. Then, we determined the chromatin texture quantitatively by calculating 3D gray-level co-occurrence matrices (3D GLCM) and 3D run length matrices (3D GLRLM). Finally, to demonstrate the suitability of 3D texture features for grading, we performed a discriminant analysis. In addition, we conducted a principal component analysis to obtain optimized texture features. Automatic grading of cell nuclei using 3D texture features had an accuracy of 78.30%. Combining 3D textural and 3D morphological features improved the accuracy to 82.19%. As a comparative study, we also performed a stepwise feature selection. Using the 4 optimized features, we could obtain more improved accuracy of 84.32%. Three dimensional texture features have potential for use as fundamental elements in developing a new nuclear grading system with accurate diagnosis and predicting prognosis.

The subjective question is appropriate for evaluation of deep thinking, but it is not easy to score. Since, regardless of same scoring criterion, the graders are able to produce different scores, we need the objective automatic evaluation system. However, the system has the problem of Korean analysis and comparison. This paper suggests the Korean syntactic analysis and subjective grading system using the syntactic-semantic tree comparator. This system is the hybrid grading system of word based and syntactic-semantic tree based grading. This system grades the answers on the subjective question using the syntactic-semantic comparator. This proposed system has the good result. This system will be utilized in Korean syntactic-semantic analysis, subjective question grading, and document classification.

This study investigates the effect of a grading of aggregate on the properties of concrete. It is a common sense in Korea that the production of coarse aggregate in ready mixed concrete industry excludes particular aggregate size ranged from 5 mm to 13 mm for saving the production cost. This causes a gap grading of the aggregate for concrete, which can lead to the increase of unit water, the development of drying shrinkage-induced crack and the reduction of compressive strength. In this study, conventional aggregate obtained from a ready mixed concrete factory and the aggregate with a modified grading produced in lab. condition were prepared. Results showed that a good grading of aggregate (i.e., the ratio of 5~13 mm and 13~25 mm is 6 to 4) produced in the lab. condition significantly improved the slump and the compressive strength of the concrete.

This study was conducted to establish a comprehensive guideline for grading system of poultry meat cuts. Slaughter and further processed houses were divided into large(>70,000 heads/day), middle($50,000\~25,000$ heads/day), and small scale(<25,000 heads/day), and the production managers were asked by the Questionnaire. Most poultry meat cuts produced by larger- and middle-slaughter house were consumed by dealers, franchisee and department store in increasing order, whereas further processed poultry meat cuts(small scale) provided meals for the students in the high amount. The packaging step was best f3r the determination of grading in the large slaughter house. This survey indicated that two or more grades were proper to determine the grading in the middle slaughter house, however only two grades were proper for the others. Freshness, bruise, wound, trimming and the inclusion of foreign materials affected to the grading. Poultry meat cuts were accepted for the grading in large-slaughter house, but whole poultry carcass was accepted for the grading in the others. Most managers agreed with that the grading system was only applied for the amounts requested. They also suggested that the grading system of poultry meat cuts were necessary in near future, even though it was not urgent to apply.

It is important to estimate objectively in the driving test. Especially, the driving test is examined by totally driving ability, rule observation and situational judgement. For this, a grading automation system for driving test was presented by using GPS, sensor data and equipment operation informations. This system is composed of vehicle mounted module, automatic grading terminal, data controller, data storage and processing server. The vehicle mounted module gathters sensor data in the car. The terminal performs automatic grading using the received sensor data according the driving test criterion. To overcome the misposition of vehicle in the map due to GPS error, we proposed the automatic grading system by map matching method, path deviation and return algorithm. In the experimental results, it was possible to grade automatically, display the right position of the car, and return to the right path under 10 seconds when the vehicle was out of the shadow region of the GPS. This system can be also applied to the driving education.
