The aim of this study was to develop a body type suitable for adult men aged from their 20s to their 40s and to present a method of drafting related patterns. To this end, the somatic surface pattern data from previous studies were used. The research method involved drafting torso patterns for each type by setting and distributing the ease to the somatic surface pattern. Appearance evaluation was performed with virtual clothing. Then, the torso pattern for each body type was completed and presented as a draft method. SPSS was used for data analysis in this study. The research results are as follows. Types 1, 2, and 3 were set to 7%, 6%, 5%; 7%, 6%, 4%; and 6.5%, 7%, and 6% for chest, waist, and hip circumference measurements, respectively. The ratio of front to back was 50%:50%, 50%:50%, and 50%:50% of the spare for each body part for Type 1; 70%:30%, 50%:50%, and 60%:40% for Type 2, and 60%:40%, 70%:30%, and 60%:40% for Type 3. A tight-fit torso pattern for each body type suitable for adult males in their 20s to 40s was drafted, which was modified and supplemented through the evaluation of the first and second virtual wear. Considering the practicality of this approach, for generalization of the patterns, the items of the pattern were converted into a drafting method and presented as a draft method.

This study aims to suggest the proper ease for slim-fit jackets according to the number of buttons from a one-button jacket to four-button jackets for men in their 30’s. The researchers carried out both an appearance evaluation and movement functionality evaluation. The results are as follows: When conducting the appearance evaluations, meaningful differences were found. The one-button jacket showed high scores for the 7.5 cm ease. The two-button jacket and the three-button jacket showed high scores for the 10.5 cm ease. The four-button jacket showed a high score for the 13.5 cm ease. Next, the results of the movement functionality evaluation showed the same trend; as the ease was increased from 7.5 cm to 13.5 cm, the scores increased. This is because if the garments offer more ease, this gives room for actions. Additionally, it showed that if there were fewer jacket buttons, then the results showed a high score. The researchers believe that if the number of jacket buttons is lower, then the area of the V-zone increases, so that there is more room for movement. The study suggests a proper chest ease of 7.5 cm for the one-button jacket, 10.5 cm for the two-button jacket and three-button jacket, and 13.5 cm for the four-button jacket, respectively.

The recent fashion market failed to satisfy the needs of female customers in their 30s who are demanding a slim jacket that makes the wearer look young and slim. Accordingly, the slim-fit jackets of domestic brands targeting the women in their 30s were collected to conduct look and movement fitting evaluations based on the standard somatotype, and a slim-fit tailored jacket prototype was developed based on the present findings. This research aims to increase the satisfaction level of the slim-fit jacket customers reflecting a variety of somatotypes of women in their 30s. The research process was developing jacket patterns fully reflecting the properties in terms of extra space and design lines for different somatotypes of women in their 30s based on the jacket pattern formulated through the advanced research, and then suggesting pattern design methods for the different somatotypes. In this sense, this research attempted to identify the problems concerning the slim-fit tailored jacket fitting for different somatotypes of women in their 30s. The main aim was to suggest ways to improve the customers’ satisfaction level regarding the fit, and enable the manufacturers to produce a well-fitting jacket reflecting the peculiarities of each somatotype.

Reflecting the consumer’s desire to look young, the “down-aging” trend, which blurs the distinctions between age groups, is the latest craze in the fashion market. The popularity of this trend made brand identities similar, resulting in customers becoming more interested in segmented notions of fashion (in terms of the story, design, high-quality material, etc.) regarding the product, and in particular, focus has become oriented to the fitness to the human body. In this sense, the researcher aimed to develop the prototype of a slim-fit tailored jacket that fits the standard somatotypes of women in their 30s well. For the purpose of this research, slim-fit tailored jackets from existing brands were collected and analyzed, and a subsequent wearability test was conducted based on the standard somatotype of women in their 30s. The research patterns were prototype of the developed slim fit tailored jacket are bust size of 3.8 cm, waist of 7 cm, and hip size of 3.8 cm. Then the research patterns were selected to develop the prototype of a properly fitting slim-fit tailored jacket. As outlined above, the development of a slim-fit tailored jacket prototype for the standard somatotypes of women in their 30s was conducted by solving the fitness issues of existing brands in order to produce properly fitting jackets that satisfy consumers.

In recent days composite bridge decks are increasingly used to new and rehabilitated bridges due to their many advantages such as light weight, high strength, high durability, low maintenance costs and fast installation. To further promote usage of composite bridge decks, the authors have developed decks of new profile having innovative vertical snap-fit connection. Through this development, significant enhancement of constructability and economy are obtained by overcoming the drawbacks of conventional composite decks of tongue-and-groove connection. The paper introduces some research results and notable applications for the developed composite decks of snap-fit connection using for pedestrian bridges. Owing to their considerable advantages of the developed composite decks, increasing number of applications is currently underway in Korea.

This research aims to analyze jeans possession and perceptions of jeans' fit among women in their 20s to help improve the accuracy of purchase decisions in online shopping and to provide basic data necessary to overcome limits in the fit conveyance method of online shopping malls. A sample of 149 females in their 20s was divided into two groups according to height, waist size, and interest in fashion, and several factors were analyzed: jeans possession status, the fit of purchased jeans, the reason for purchase, and the perception of jeans' fit. The results are as follows. The group with a high interest in fashion owned more skinny jeans, and there was a higher frequency of purchasing skinny jeans during the last year among those with a height of 160 cm or more, a waist size of less than 27 inches, and a high interest in fashion. Of the respondents, 92.6% accurately understood skinny fit, 51.7% understood straight fit, and 56.4% understood regular fit. There was no significant difference in the perception of skinny fit or regular fit, but straight fit was better understood by the group with a waist size of 27 inches or more. Thus, by providing accurate size information and analyzing the body shapes of consumers, online shopping malls will be able to increase customer satisfaction with pants of various fits to reduce the rate of returns.
