This study aimed to investigate whether women's wear brands' sizing systems for pants item are reflecting body size and shape of their target age customers. This study classified 17 women's wear brands into three target age groups (20-30s, 30-40s, and 40-50s) and surveyed their body sizing systems of pants item. Distribution of waist circumference and hip circumference of brands' sizing systems were compared with size distribution of women in the 7th Size Korea data. The sizing systems of brands targeting 20-30s covered 28.3% and those of brands targeting 40-50s covered 27.3%, while those of brands targeting 30-40s covers 46.6%. Regarding the body types, 80% of 20-30s target brands reflected normal type which is the average body type. However, all 40-50s target brands reflected normal type while 57.8% of women aged 40-50s had large waist shape. The 30-40s target brands reflected body types the best among target age groups since the body shape distribution of the brands was similar to that of 30-40 year old woman in Size Korea. For each age group, 6 sizes with 25.2~27.8% coverage rates were proposed. The 70-91, 73-91, 73-94 sizes were overlapped between the 20-30s and the 30-40s groups. The 76-91, 76-94, 79-94 sizes were overlapped between the 30-40s and 40-50s groups. Pants size has been found to increase in waist circumference compared to hip circumference as age increased.

The purpose of this paper is to analyze the double stylobate of the three-story stone pagoda in Yeongnam region and to divide the types of arrangements of the body-stone and roof-stone and find their correlation. Research objects are 47 three-story stone pagodas in Yeongnam region which have accurate documents and plans. After dividing a double stylobate of three-story stone pagodas into a lower and upper stylobate, we classified each stylobate into a type of body-stone and roof-stone from an architectural point of view. Types of arrangement of body-stones are divided into methods of using the 'ㅡ' shaped stone and methods of using 'ㄱ' shaped stone in the corner. And types of arrangement of roof-stones are divided into methods of arranging stones in a row or in a grid pattern. As the size of the pagoda increases, 'ㄱ' shaped stones used for the body-stone and stones for the roof-stone are arranged in a grid pattern. As the size of the pagoda becomes smaller, the body-stone is consist of 'ㅡ' shaped stone, and the roof-stone is arranged in a row. As the construction year of the pagoda becomes later, the size of the pagoda becomes smaller and types of body-stone and roof-stone had been stereotyped. As a result, the size of the stone pagoda became smaller as constructed later, and the type of body-stone and roof-stone of the double stylobate appear differently according to the size of the pagoda.

In this study, we investigated the grain size, lithological type, and shape of coarse bed materials in the upper and middle reaches of Gongneungcheon River. For this purpose, 11 sampling points were selected along the river. For 100 samples of the coarse bed materials at each point, three axes (long, intermediate, and short) of samples were measured, and their lithological types were also identified. By measuring grain size, the sphericity and flatness of samples were calculated. Finally, every particle was classified into four shape categories: sphere, disc, blade and rod. We found that the grain size in incised meandering reach is the largest. This is mainly due to the supply of coarse materials from steep valley sides along the meandering channel. According to the lithological analysis, all samples were identified as granite, gneiss and schist, and quartz. The proportion of granite decreased, whereas the proportion of gneiss and schist increased downstream. These patterns indicate that the bedrock distribution within the study area accounts for the downstream lithological variation of coarse bed materials. With regard to the grain shape, sphericity gradually decreased while flatness gradually increased downstream. In the case of the shape classification, unlike the general downstream pattern of grain shape, the proportion of the sphere type decreased and the proportion of the blade type increased downstream. Such a reversal change in the downstream direction turns out to be determined by the lithology (such as foliation, bedding and the pattern of weathering) of coarse bed materials.

콘크리트 도로 상판 또는 터널 라이닝의 배면 공동은 구조물의 함몰 또는 붕괴로까지 이어질 가능성이 있다. 이 공동을 비파괴로 검출하기 위한 방법 중의 하나가 저주파수대 레이더(GPR)의 사용이다. 그러나 이와 같은 토목구조물에는 분해능이 좋지 않은 저주파수대의 레이더를 사용할 수밖에 없기 때문에 작은 공동의 크기나 두께까지 탐사하는 일은 현재 기술로는 거의 불가능하다. 본 연구는 이와 같은 문제와 한계를 극복하기 위해 다양한 공동의 크기와 두께, 깊이를 대상으로 많은 량의 실측 실험을 통해, 저주파 레이더 측정치와 공동 간의 상관관계를 분석함으로 해서 공동의 깊이, 크기와 두께까지를 추정하기 위한 새로운 해석방법을 제안하고 그 적용성을 검토하였다. 또한 본 검토에서는 공동만을 그 크기(횡폭)에 맞게 화상처리에 의해 나타낼 수 있는 역치를 산정하였다. 그 결과, 본 연구에서 제안된 방법에 의해 실험실 수준에서는 정도 좋게 공동의 깊이와 크기, 두께를 추정하는 것이 가능하였다.

Abstract The purpose of this study was to propose a new size-spec. which was applied to four frontal bodytype -X, Y, A and H type-of adult women. Control dimensions of the upper garments were stature bust girth and hip girth. And those of lower garments were waist girth and hip girth. To establish the interval of the control dimensions means and standard deviations were used. By distributing the data of 486 subjects a new size-spec. was proposed. According to the new size-spec. in case of upper garments about 45.7% of subjects were covered by 37 size-speces. and lower garments about 85.9% were covered by 36 The strong point of new size-spec. is to consider the formal feature of each bodytypes. So by trying to apply the new size-spec. to rady-made garments comfort and fitness of those are satisfied.

This study proposes a method for determining the optimal target size for an artillery range considering ballistics and environmental conditions. To this end, the size of the probable error of each type of ammunition and charge determined during shooting were considered, and the effect of the firing position and target terrain characteristics on the target size was analyzed. In conclusion, the size of the target increased as the range increased, and a larger target size was required for the DPICM than for the general high explosive. Accordingly, the optimal target size must be determined by considering various factors such as topographical characteristics, shooting position location, and shooting range safety standards.

The approximation of the radial distribution functions(RDF) of mixture plays an important role in deriving the mixing rules for the corresponding states principle(CSP). The mean density approximation(MDA), one of the most successful approximations, fails to predict the radial distribution functions when the size ratio in terms of the Lennard-Jones size parameters is greater than 1.5. To get a better prediction of important structural integrals over the radial distribution functions that arise in the asymmetrical attraction contribution of the perturbaton theory, the new type of mean density approximation(NTMDA) is proposed. With this NTMDA, quite reliable results for those integrals for systems with comparatively large ratio of the size parameters are obtained.

A defect which is axially oriented with small size is hard to detect in conventional system. CMFL(Cricumferential Magnetic Flus Leakage) type PIG(Pipelines Inspection Gauge) in the NDT(Nondestructive Testing), is operated to detect this defect called axially oriented cracks in the pipe. It is necessary to decompose the size and shapes of cracks for the manintenance of underground pipelines. This article is focused on the decomposing method of the size and shape of the axially oriented cracks by using inspection signal data for defect.

The purpose of this study was to test the discriminant analysis model of Quick Response system and to examine the detailed relationship between each discriminant factor and Quick Response adoption. In this discriminant analysis model of Quick Response system, firm size, strategic type, product category, fashion trend, selling time and the Quick Response benefits were included as discriminant factors. Onehundred and two subjects were randomly selected for the survey study and discriminant analysis, descriptive analysis, t-test, and x square test were used for the data analysis. The results of this study were: 1. Wilks Lambda and F value support the discriminant analysis model that, taken together firm size, strategic type, product category, fashion trend, selling time and the Quick Response benefits significantly help to explain Quick Response adoption. 2. The importance of discriminant ability was, in order, firm size, the Quick Response benefits, women's wear, fashion trend, analyzer, selling time, reactor, defender and men's wear. 3. The discriminant function had the high hit ratio, so this can be well used for the classification of Quick Response adoption/nonadoption.
