The purpose of this study is to develop the measuring tool that can grasp the relationship between body and pattern, the result can be directly digitalized and developed as the pattern as body form is. There are 6 measurements; 1) the width of front and rear neck 2) the slant degree of shoulder 3) the degree of protrusion of breasts and scapulae 4) the separation of front and rear board 5) space between body and clothes 6) vertical strand in the clothes Developed measuring tool is handy in un. in which points of body to be measured are small, and it has the capability of designing the high fitness for body. The measurer developed through this study is named as $\ulcorner$Somato-pattern Measurer$\lrcorner$, size paper is named$\ulcorner$Somato-pattern Paper$\lrcorner$and the pattern made by$\ulcorner$Somato-pattern Measurer$\lrcorner$is named$\ulcorner$Somato-pattern$\lrcorner$respectively by our team. The result of this study is thought to make a great contribution to solving the various problems which can be derived in the time of pattern design because of the difference of physical forms in the same size as well as the difference between the factor of size and that of form in body.

This study examines the relationship between breast shape and brassiere construction through the comparative analysis of brassiere pattern on the breast shape. This researcher drew the brassiere pattern of developing a pre-study for Chinese female adults according to average size based on the four breast shapes. And then we measures brassiere pattern size and comparatively analyzes breast between size and shape. Comparative analysis results of brassiere patterns are verified differences of size and shape on the breast shape. Above all an angle of cup dart showed remarkable differences on the breast shape. An angle of cup dart isn't proportioned to breast size. An angle of cup dart for cone shape is bigger than dome shape. Because cone shape breast is protruded center part but dome shape breast have a shape of smooth curve like a half globe. So an angle of a cone shape breast cup dart is determined bigger than dome shape breast. For increasing the uplift effect of brassiere, brassiere pattern is different on the breast shape. And a brassiere pattern need different drawing methods about the angle of cup dart, breast inner side diameter, slope and so on. This study has an important significance that it established a mechanical relationship of breast shape and brassiere pattern.

Since the financial crisis broke out, liquidity has become the critical issue in housing construction industry. In order to secure liquidity, it is prerequisite to precisely forecast cash flow. However, construction companies have failed to come up with a systematic process to manage and forecast cash flow. Until now, companies have solely relied on the prediction of profits and losses, which is carried out as they review business feasibility. To obtain more accurate cash flow forecast model, practical pattern of payments should be taken into account. In this theory, basic model that analyzes practical housing payment collection pattern resulting from prepayments and arrears is described. This model is to complement conventional cash flow forecast scheme in the phase of business feasibility review. Analysis result on final losses in cash that occur as a result of prepayment and arrears is considered in this model. Additionally, in the estimation of construction cost in the phase of business feasibility review, real construction prices instead of official prices are applied to enhance accuracy of cash outflow forecast. The proportion of payment made by a bill and changes in payment date caused by rescheduling of a bill are also factored in to estimate cash outflow. This model would contribute to achieving accurate cash flow forecast that better reflect real situation and to enhancing efficiency in capital management by giving a clear picture with regard to the demand and supply timing of capital.

This study provides basic guidelines to enrich lecture content and teaching methods for university lecturers about basic clothing construction (flat pattern making). The survey was conducted from October $13^{th}$ to December $20^{th}$ 2010 by mail and e-mail on 96 selected clothing departments in Korean universities to investigate the content, method and condition of the course of basic pattern making. A total of 63.3% of survey respondents were PhD graduates, 80 percent majored 'Apparel Science and Technology', average of total teaching experience was 12.84 years and 40 percent had studied abroad. The surveyed universities were 4 year universities (70%), 2-3 year tenure colleges (27%), and Cyber Universities (3%). The average number of students in a class was 28.08 and the lab space and equipment was evaluated positively only when the number of students was 20 or less. The type of measurements for basic pattern drafting were 'individual student's sizes' (62%), 'ready-made clothes sizing system' (25%), 'professor's experiential sizes' (5%), 'dress form sizes' (3%). In addition, the percentage of using 'ready-made clothes sizing system' increased 13% over the previous study (Lee, 2000). At a basic pattern drafting stage, 'the error of body measurements' in the case of using individual student's sizes, 'the poor results of fitting for students who deviate from standard body size' in the case of using ready-made clothes sizing system, 'the lack of education about fitting' in the case of using dress form sizes had been pointed out as shortcomings. A total of 66% of survey respondents carried out muslin fitting; however, a lack of students and teacher feedback about fitting & alteration of paper patterns remained a problem.

The objective of this study is to analyze the temporal pattern characteristic of short-duration rainfall defined as a rainfall durations of 6 hours or less by the Huff's 4th quartile distribution. To analyze the temporal pattern characteristic of short-duration rainfall, the rainfall data are classified by rainfall duration and rainfall type(Changma, Typhoon, Severe rain storm, Frontal storm) and change of rainfall segment. Also, the results of this study compared with result of research work of Korea Institute of Construction Technology(1989) and Ministry of Construction & Transportation(2000). The conclusions of this study are as follows; (1) Short-duration rainfall with duration of 6 hours or less is found to be most prevalent frist-quartile storms. (2) In the case of rainfall type, Changma and Severe rain storms and Frontal storm is found second-quartile storms, and Typhoon is found third-quartile storms. (3) In the result by change of sixth segment storms, the type of temporal pattern of rainfall is found to be most prevalent two sixth parts, (4) Comparative analysis of the results shows that shapes of the dimensionless cumulative curves and values are different from those of existing researches.

A purpose of this study is to do fundamental research of construction of coat patterns in the Daehan Empire in order to make replicas of the costumes. This study is composed of literature research, investigation of artifacts, and experiment of pattern making. The results of this study are as follows. First, even if the 15th Court Dress Rules regulated color, fabric, number of flower, width of braid, and size of button, there was no regulation regarding the shape of the coat. The analysis of the photos in those periods shows that the style of the tailcoat was different from that of today in the length of the front, the shape of breast and collar. Second, six artifacts in the collection showed that the shoulder line and the sideline were located on the further rear side than the current tailcoat. This can be confirmed in the western and Japanese pattern book, and especially the pattern drafting method in the books published in Japan in 1900s is different from current one in setting base lines of front bodice and back bodice. As a result, based on several experiments, this study proposes how to make coat patterns. The shoulder line, the sideline, and the princess line should be located in the back of the dress similar to the shape of swallowtail coats of 1900s. The front bodice should be constructed without the composition line in order to add embroidery on it. The collar, which shape looks like long half moon, should form V-shape neckline in the front breast when adjusting dress. The sleeves should be constructed top and down, and it should curve more than the modern design.

According to the design method for constructing the crotch angle of traditional Korean men's trousers there are differences in from after its completion. Since there is no standardization of visual & aesthetic pattern for the construction method which is stablished by the calculation formular of waist girth hip girth pantleg end and upper outer leg length it is difficult to be used for educational use or for teaching materials. Therefore the purpose of this project according to five models in proportion to the physical standard of Korea in ages from 24 to 29 years old is to establish a design criterion and the standardization of construction methods by introduction the pant construction method of the crotch angle by converting the sitting posture length to seaming crotch center point both knees width in the Korean way of sitting. The production method for the pattern design is as follow: (1) The waist girth formular is {{{{ { w} over {4 } }}}}+{{{{ {w} over {10 } }}}}(2) The hip girth formular is {{{{ {H } over { 4} }}}}+{{{{ {H } over {5 } }}}}(3) The pantleg end formular is {{{{ {H } over {4 } }}}}(4) A crotch angle is fixed at 70 degress.(5) The ratio of outer leg length to leg width is 5:8 (6) The component ratio of the upper outer leg length to the pant length in 5:8(7) The ratio of the division point of front / right inner leg length and left inner leg width to upper outer leg length is 5 : 8
