The purpose of this study was to develop brassiere pattern designed to fit the breast shapes based on ESMOD pattern. It has three quarters cup round shape and also consists of three parts; upper cup, lower cup, and wings. Breast types are classified into five shapes; ideal breast, flat breast, upper developed breast, lower developed breast, and projecting breast. Two subjects for each breast type wore the brassiere, and they evaluated the appearance and wearing twice. Type I for research pattern designed to fit into the breast shape reflecting details of breast size were assessed as superior to the divided commercial type. However, wings' tightness of Type I for research pattern brassiere was high. Thus, to improve wearing satisfaction, extra was added to wing. Based on the results of wearing experiments of Type I for research, we adjusted and modified Type II for research pattern. Subsequently, its appearance and wearing were evaluated, in order to be improved. For upper developed breast pattern, we extended the length of lower part to balance upper and lower part, as the upper part was somewhat long. The lower developed breast has the closest feature to the ideal breast, suggestive that implies it does not require much improvement Projecting breast pattern has minimal space in the lower part, so we added the support to lift them to be similar to the ideal breasts. For all the breast shapes, we reduced the wings' tightness from 8% to 7% so that we could extend the length of the wings.

The effect of coolant flow pattern on the metal temperature of the combustion chamber was studied in 1.5L and 1.8L gasoline engines. One of the main important points in the design of the water jacket is the increase of the coolant flow velocity. In this paper, the water jackets of the cylinder head and the cylinder block were visualized for the purpose of improving the coolant flow pattern. By the use of this technique, the optimal design of the size and th location of the water transfer fole was possible. And, to lower the metal temperatures of the thermally critical parts, the drilled water passages were employed. To investigate of effect of the improved flow pattern and the drilled water passages, the metal temperatures of the combustion chamber were measured. As a result of the temperature measurement, it was found out that both the change of flow pattern and the drilled water passages have significant effect on the reduction of the peak metal temperature.

This study examined four subjects with close to average body-size values in four stages based on the average BMI value of middle-aged women aged 45 to 59 years. The first experimental pants was developed with two kinds of educational materials pants pattern. After using a clothing-suitability evaluation to identify problems, a pants pattern suitable for the body shape of middle-aged women was developed by modifying and supplementing the initial design. The fit assessment revealed that pattern A had a problem with wrinkles in the hip and thigh areas due to the long crotch length, and pattern B had a short bottom length, which caused the bottom to curl in toward the groin or for the bottom to stick at the hips. The second experimental pants was developed to address these issues and overall satisfaction with the dimensions was higher than for the first educational pattern. The proper front and rear length extensions satisfied movement functionality and appearance requirements, and increasing the gradient of the back centerline-rather than expanding the width of the back crotch-improved the functionality.

The rise of crowdsourcing and web 2.0 opens plenty of opportunities for companies who want to exploit external sources of ideas for internal innovation. Utilization of crowdsourcing for product design and development has been attracting the attention of both enterprises and researchers. Many cases of implementation of crowdsourcing for product design and development such as: Threadless, FIAT Mio, Lego online Factory, etc., have made crowdsourcing a promising alternative source of innovative power. Although crowdsourcing gained access due to improved Internet access and web 2.0, it is little understood how the crowd, with respect to participation, behaves for any crowdsourcing project. To investigate this, we conducted an experiment on a real crowd of engineering related individuals to figure out the crowd participation pattern for various product design and development phases of a new product development project. The experiment results give a quantitative view of the participation of the crowd (i.e., crowd participation pattern) in various phases of a product design and development process that utilizes crowdsourcing, provide a practical guidance for companies to harness the power of the crowd sensibly, and provide experimental data for further research in this field.

This paper pursues a comparative study on the design and function of the ready-made Bo-Son and the Bo-Son Pattern based on teaching and learning materials. It intends to investigate whether the Bo-Son is designed to suit to Kinetics of foot or to give the ease of wearing and taking off. The following results came out through trial wearing. 1) The Bo-Son pattern suggested in teaching materials can not satisfy the wearers with partial modification due to design problem. On the other hand, the ready-made Bo-Son can satisfy them with partial modification. 2) The important factor in designing the pattern of Bo-Son is the posture of foot when putting on it, that is, the height of the heel of the foot from the floor, the length of the heel, the length of toe and the bending angle of toe. 3) As a result of this study, in the design of the improved Bo-Son pattern, it is most suitable when the size of foot is 230mm, the height of the heel of the foot is 12.5cm, and and angle of the front toe of a sock is 35$^{\circ}C$.

By analyzing five in-depth case studies of suppliers in newly emerging Vietnam's motorcycle industry, this paper explores the differences in patterns and processes of capability improvement of suppliers who participate in different kinds of supplier-assembler network with different structures. The paper finds the correlation between the kinds of suppliers' capabilities improved and the structure of networks they participate in. While suppliers in arm-length networks can improve more upstream capabilities (structure design, process desist), suppliers in embedded networks can improve more downstream capabilities (process design, process setup, process maintenance and delivery control). Two capability improvement patterns of firms in newly emerging economy are indicated. The first pattern is asymmetrical improvement, either upstream or downstream capabilities, by participating in either arm-length or embedded networks. This pattern obstructs the suppliers to meet the requirements of new buyers rho come from different kinds of network. The second pattern is symmetrical improvement by joining both arm-length and embedded networks.

Recently, the quality and design of the children's wear is being improved remarkably. Following the trend, the need for the research on the pattern making of children's wear is growing. At first, we tried to find out how the industry is doing the pattern making job through interview. Results are as follows. The target age ranges from 5 to 11 years old. For the sample size of pattern making, 7 years of age is preferred. It is not usual to develop the design pattern from the bodice block pattern. Instead, they use middle block pattern for each item, such as blouse, shirt, pants, skirt or jacket. Starting from these middle block pattern, they prepare individual designs. With the results, the aim of the research became to develop one of most frequently used middle block pattern. The blouse block pattern was selected for that purpose. To look into the existing patterns, we selected 4 methods, i.e. NM-method, T-method, O-method, E-methods. Theses patterns were compared through wearing test for the evaluation of comfort and fit using trial garments. The results indicated the NM-method was best among them. Specially waist line position, shoulder shape and size allowance was adequate. Alteration and adjustment of pattern draft was made onto the NM-method. Allowances for the bust circumference, across chest, across back and depth of arm was adjusted for better comfort as well as fine fit. Sidelines of the bodice and the underarm seam of the sleeves were curved for styling. After another wearing test, the final pattern was suggested as a blouse block pattern for 7 years old girl.

The adjustment of lens magnification can make the degree of precision in pattern measurement be improved, but several problems such as high cost, smaller field of view and stage error accumulation are followed. In this paper, a method for precisely measuring patterns is proposed based on gradient transition vector, in order to solve these problems. The performance of our method is evaluated using pattern images with several directions. Also, it is compared with previous methods based on edge and gray-level moment. It is judged that the proposed method outperforms consistent pattern width results, and so could be applied to automation processes for measurement and inspection of precise and complexed patterns in IT, BT industry products.

The purpose of this study was to develop the beautiful basic bodice pattern that satisfied both functionality and aesthetics on the basis of the change in the figure and length of surface body for each movement through a three-dimensional development figure of surface body for young women (aged between 18 and 24) who were very sensitive to fitness of clothes. Existing three basic bodice patterns (Yim wonja-, ESMOD-, and FIT-types) were selected and then compared and analyzed in terms of drawing methods and the wearing test was carried out by a sensory test in order to design an experimental prototype. The design of study prototype was improved by three wearing test that was correlated with low satisfactory item. And the ease was established by difference of previous direct measurement and body surface measurement.
