The study provides baseline data on developing ready-to-wear clothes for adult females in their twenties who have finished shaping their bodies and have realized an ideal shape. We analyzed the data from females aged from 20 to 29 in "The $5^{th}$ Size Korea Survey" and "The $6^{th}$ Size Korea Survey", and sorted body shapes into several types according to drop values before analyzing and comparing the characteristics among groups. We also referred to the change by year in the size of upper inner wear. To classify body shapes, three drop values were assigned for bust girth - waist girth, hip girth - waist girth, hip girth - bust girth; through cluster analysis all data were classified into three body types. Type 1 is more like normal body shapes with small drop values at the bust girth - waist girth and well-build lower body. Type 2 is X-shaped body shaped like a fiddle with big drop values at all parts. Type 3 is Y-shaped body with a big drop value at the bust girth - waist girth and well-build upper body. Type 2, X-shaped body, has the majority of distribution in every year, which proved to be the most idealistic body shape. There was a change in the brassiere cup size. Korean ladies in their twenties have larger breasts. The body shapes of Korean females in their twenties are increasingly like those of westerners. Bust girth is a very critical element to set measurements and design patterns for upper wear; consequently, a change in the size of breasts should be considered.

In this paper, The classification between precipitation echo(PRE) and non-precipitation echo(N-PRE) (including ground echo and clear echo) is carried out from weather radar data using neuro-fuzzy algorithm. In order to classify between PRE and N-PRE, Input variables are built up through characteristic analysis of radar data. First, the event classifier as the first classification step is designed to classify precipitation event and non-precipitation event using input variables of RBFNNs such as DZ, DZ of Frequency(DZ_FR), SDZ, SDZ of Frequency(SDZ_FR), VGZ, VGZ of Frequency(VGZ_FR). After the event classification, in the precipitation event including non-precipitation echo, the non-precipitation echo is completely removed by the echo classifier of the second classifier step that is built as Type-2 FCM based RBFNNs. Also, parameters of classification system are acquired for effective performance using PSO(Particle Swarm Optimization). The performance results of the proposed echo classifier are compared with CZ. In the sequel, the proposed model architectures which use event classifier as well as the echo classifier of Interval Type-2 FCM based RBFNN show the superiority of output performance when compared with the conventional echo classifier based on RBFNN.

본 연구는 수학 및 과학 영재 아동과 일반 아동의 성격유형과 학습양식의 차이를 알아보는 것을 목적으로 하였다. 이를 위해 수학 및 과학 영재교육을 받고 있는 부산광역시 소재의 초등학교 5, 6학년 135명과 일반아동 66명을 대상으로 하여 MMTIC과 학습양식검사를 실시하였다. 성격유형의 분석은 선호지표와 기능별, 기질별 분포를 중심으로 하였고, 학습양식은 독립형, 의존형, 협동형, 경쟁형, 참여형, 회피형의 유형으로 분류되었다. 연구결과에 의하면, 수학 및 과학 영재 아동은 성격유형, 학습양식 그리고 성격유형에 따른 학습양식에서 큰 차이가 없었으나, 일반 아동과는 유의한 차이를 나타냈다. 또한 연구대상의 성격유형에 따라 선호하는 학습양식에는 차이가 있는 것으로 나타났다.

The purpose of this study is to classify the body types of obese men in their 50-60s and compare them with those of obese middle-aged men in their 30-40s. The 3D anthropometric data of obese men aged 50 to 60 years from the 6th Size Korea. The data are analyzed using SPSS 25.0 for Windows, and descriptive statistics, χ² test, correlation analysis, and cluster analysis are used to classify obese body types. As a result of the study, five factors are extracted to determine body types, which are classified into three obese body types through cluster analysis. 1) a large physique and consequently large circumference and height; 2) A short upper body length, short height, and thick belly; 3) the lowest rate of obesity and relatively flat abdominal curve. For the 30-40s group, Type1 showed the highest rate at 55.6%, whereas for the 50s group, Type3 showed the highest rate at 49.3%, and for 60s group, Type2 showed the highest rate at 41.2%. The classification accuracy of the discriminant function for each type is 94.7%, indicating relatively high accuracy. Furthemore, the recently changed obese body type are analyzed by comparing it with the 3D anthropometric data of 8th Size Korea, which will contribute to the utilization of basic data for manufacturing apparel for obese men.

The aim of this study is to classify the life styles of urban housewives, to see their correlation with demographic and socioeconomic variables, and finally to provide some useful for their ideal home management. This study has been based on a questionnaire on the demographic characteristics of housewives, and their life styles. The selected samples were 650 and 514 of them were analyzed. The data wee analyzed by factor analysis, cluster analysis, ANOVA, Duncan test and X2-test. As a result of factor and cluster analyses of 64 items th life styles of urban housewives were classified into 5 types; 'conservative stagnant type', 'sound and thrifty type', 'passive stagnant type', realistic and stable type', modern and evolutional type', The life styles of the respondents showed significant differences by the variables of age , family life cycles, the number of family members, the number of children, family type, education, occupation, income, the type of housing, and religion.

The purpose of this study is to classify of the Metal Feathered Trim in old tombs. First, Feathered Trim is 5 types, Feathered Trim I-A, Feathered Trim I-B, Feathered Trim II-A, Feathered Trim II-B, Feathered Trim II-C in according to upper part of central insert plate style. Feathered Trim I-A, I-B, II-B type was general style that was found in most of the old tombs in ancient Silla, Gaya. Feathered Trim II-A type was excavated from the only Silla tombs and II-C type was excavated from Gaya tombs. Feathered Trim I-A type was worn previous to I-B type, and II-B, C type was worn previous to II-A type. Feathered Trim 5 types was influenced by the scythe style that was 'Scythe-shaped' tail.

Silica bodies (phytoliths) are becoming of wide use for pedology, archaeology, paleobotany and paleoecology in botany. This study investigated morphological differences of silica bodies in the lamina of wild, indica type, and japonica type rice. Phytoliths in the epidermis of lamina showed noticeable difference among tested plants. Besides, there were also significant differences in the shape and distribution of the silica bodies around stomata and trichomes. Silica bodies in the lamina of the rice plants could be used to classify subspecies of Oryza genus.

This paper concerns the relation between the degree and the projective dimension of linear systems on curves. We generalize Clifford's theorem and its improvement by Coppens and G. Martens and classify the special curves for our problem, and estimate their gonality.
