This study is conducted to improve the fitness of Air Force winter service uniforms pants through the development of a pants pattern drafting method and automatic pattern drafting program for mass customization. The initial study pattern drafting method is formed through an analyses of 4 kinds of conventional pants pattern drafting methods for education and 3 kinds of conventional pants patterns of Air Force apparels. The initial study pattern drafting method is converted into the final study pattern drafting method after twice conducting a wearing test. To verify the final study pants pattern, a motion adaptability evaluation, an ease amount evaluation and an appearance evaluation are conducted. The results of the final study patterns were better than conventional winter service uniforms in the motion adaptability evaluation and the appearance evaluation. However, the results show similar values between the final study patterns and conventional winter service uniform patterns in the ease amount evaluation. An automatic pattern drafting program was developed based on the final study pattern drafting method. The program allowed the achievement of customized pants patterns through the placement of customer body sizes into the size input window. It also provided two kinds of ease amount and two kinds of waist belt level options.

This study aimed to investigate the status of ready-made suit and MTM (Made-to-measure) suit production with 10 men's suit brands turning over 200 billion won. Their target age group is late 30's to late 40's. Regarding production for the ready-made suit, eight out of 10 brands are using both KS and their own sizing. Classification of body shapes was done in 8 brands, mostly for upper body in simple ways (lean, normal, and obese). All brands are conducting fittings on only standard size. The number of sizes produced is varying depending on the brands; 9 to 17 for a jacket and 9 to 20 for a pair of pants. Regarding on the MTM production, four out of 10 brands have implemented MTM production. The rate of MTM production to their total production is about 15-20%. There were positive opinions on MTM production since it enables to reduce stocks through a small quantity of production for necessary sizes only. The reasons of orders of MTM production were answered as 'no size available', 'unique body shape', etc., and most orders were placed by consumers who are fat-bellied or have thick thighs. They have used MTM automated CAD software developed by Gerber Technology or Investronica. All the brands have utilized automated marker-making software and cutting facilities for MTM production.

Mass customization (MC) is a business practice that aims to provide customers with customized products and services at near mass production efficiency. To achieve the aim, a number of methods to implementing MC are proposed. However, most of them require changes in entire process of the company, which make companies hesitate to implement MC even if it is essential to survive. In this paper, we proposed alternatives to partially implement MC for quick adaptation of MC. The base line assumption is not to change the production lines. The pros and cons of alternatives are given by qualitative and quantitative evaluation. Especially, by giving radar chart analysis of the quantitative measures, we give insight on the changes in the business performance measures, such as time to market and cost. Proposed alternatives are based on sub-processes such as purchasing raw materials, production process changes and packaging for efficient logistics. In this way, companies are able to provide customized products with small changing of the current manufacturing system. The process and benefit of the proposed strategy is verified by real world cases of a Korean health food company.

Recently, the industry actively adopts the cutting-edge technologies of the fourth industrial revolution and uses them to enhance the productivity and service of mass-customization. The manufacturing industry is creating new processes and business models by achieving digital transformations through a lean start-up approach aimed at achieving the highest customer satisfaction with minimal resources. Although attempts are made to manufacture the building by introducing the latest technology in architecture, it is applied sporadically, not as an integrated system, in the entire phase of the architectural project. This paper analyzes the changes in the construction industry through the application of core technologies of the fourth industrial revolution. Design processes are analyzed for the digital transformation of the construction industry by case study of advanced architectural design practice. A novel design concept model 'Architectural lean startup' is proposed by combining the architectural process and the lean start up method. Through the design of the bus stop based on the architectural lean startup concept, it is confirmed that the designer repeats the 'Generate-Test-Analysis' to develop the design and generate the final result.
