Accurate and automatic clothing pattern making is very important in personalized clothing customization and virtual fitting room applications. Clothing pattern generating as well as virtual clothing simulation is an attractive research issue both in clothing industry and computer graphics.

Physics-based method is an effective way to model dynamic process and generate realistic clothing animation. Due to conceptual simplicity and computational speed, mass-spring model is frequently used to simulate deformable and soft objects follow the natural physical rules. We present a physics-based clothing pattern generating framework by using scanned human body model. After giving a scanned human body model, first, we extract feature points, planes and curves on the 3D model by geometric analysis, and then, we construct a remeshed surface which has been formatted to connected quad meshes. Second, for each clothing piece in 3D, we construct a mass-spring model with same topological structures, and conduct a typical time integration algorithm to the mass-spring model. Finally, we get the convergent clothing pieces in 2D of all clothing parts, and we reconnected parts which are adjacent on 3D model to generate the basic clothing pattern.

The results show that the presented method is a feasible way for clothing pattern generating by use of scanned human body model.

The main contribution of this work is twofold: one is the geometric algorithm to scanned human body model, which is specially conducted for clothing pattern design to extract feature points, planes and curves. This is the crucial base for suit clothing pattern generating. Another is the physics-based pattern generating algorithm which flattens the 3D shape to 2D shape of cloth pattern pieces.

The purpose of this study is to advance a novel evaluation index system and evaluation approach for ability of older adults in China.

This study constructed a comprehensive older adult ability evaluation index system with 4 primary indicators and 17 secondary indicators. Grey clustering analysis and entropy weight method are combined into a robust evaluation model for the ability of older adults.

The result demonstrates that the proposed grey clustering model is readily available to calculate the disability level of elderly individuals. The constructed index system more comprehensively considers all aspects of the disability of the elderly.

This study provides a quantitative method and a more reasonable index system for the determination of the disability level of the elderly.

The person who works in an office starts his or her day with a choice of attire. The way they look in the office depends on the decisions they make on their clothes. This study aims to identify the challenges faced by employees in the management positions in the Sri Lankan apparel industry who regularly come into contact with customers when they have to decide upon the most appropriate work attire for the position they are occupying in their organization.

Collection of data was primarily achieved through a well-structured questionnaire containing a mixture of open- and closed-ended questions. Targeted employees were managers, designers and merchandisers belonging to Generation Y whose total number was sufficient to obtain 50 feedbacks. Six more interviews were conducted with the intention of finding out more about this matter.

The majority of employees in the management positions in the Sri Lankan apparel industry who have regular contact with customers prefer to dress in “smart casual attire”, which means semi-formal clothes. Lack of availability of certain varieties of business attire in Sri Lanka proved to be a major challenge for some employees. Overpriced clothing, less comfortable clothing and lack of the right fabrics and designs were also challenges. These findings highlight the importance of manufacturing a wider variety of business attire using moderately priced but comfortable fabrics to make affordable and good quality products. There is a need to have a persuasive merchandising method to achieve good sales and provide a pleasant shopping experience to the customers.

Sri Lankan workwear retailers as well as apparel designers can benefit from the findings of this research as there is no evidence of any other studies on this subject. Therefore, this will help them to fill the market gap for business attire by addressing these challenges.
