A recent trend for product development requires that product design firms participate in every process in cooperations with clients. So, this study proposed an advanced practical management process for product design according to the new trend Because existing processes explain summary steps just including market research, design, engineering, manufacturing., to support the recent trend, an extended process which explains every steps should be prepared. Design development precesses include initial meeting, contact, kick-off meeting, market research, idea sketch, rendering, design drawing, design mock-up, design manual, engineering drawing, ES mock up, mold, manufacturing, and patent. To manage these whole design processes, designers should have abundant knowledge about them. This process has three merits: 1) understanding the whole processes, 2)the unity between design and manufactures, 3)collecting accurate information by market research, 4)elevating design quality. So, designers are able to manage whole product development processes. This practical management process proposes an advanced structure for product design development, and can be accepted for various product design development environments.

Capstone design is a creative and comprehensive educational program requiring practical adaptation skills for the industry. The purpose of this study was to analyze the results of design development, lectures and curriculum satisfaction for textile fashion products based on four years of capstone design curriculum from 2015 to 2018. The curriculum consists of 26 groups of 72 students and a total of 26 final results were obtained via industry-university cooperation. The materials for product design development included differentiated clothing, leisure goods, bags, dog goods, smart goods, interior goods and recycled products based on textiles. The degree of satisfaction with lectures involving the capstone design class was very high, with 4.2 out of 5.0 when the number of students was less than 10. However, when the number of students was 20 or higher and the number of students was large, the level of satisfaction was below 3.88. Therefore, the capstone design class comprising less than 10 students was better at individual teaching and teamwork. In terms of satisfaction with capstone design curriculum, the respondents indicated that the teaching method addressing the needs of industry and academia facilitated practical learning. It was very helpful in improving competency related to the design and development majors and future employment. The capstone design curriculum was effective in the training for practical design development and planning.

Purpose: We research on the efficient response surface methodology(RSM) design to develop a design space in Quality by Design(QbD). We propose practical designs for the successful construction of the design space in QbD by allowing different number of replicates at the box points, star points, and the center point in the rotatable central composite design(CCD). Methods: The fraction of design space(FDS) plot is used to compare designs efficiency. The FDS plot shows the fraction of the design space over which the relative standard error of predicted mean response lies below a given value. We search for practical designs whose minimal half-width of the tolerance interval per a standard deviation is less than 4.5 at 0.8 fraction of the design space. Results: The practical designs for the number of factors between two and five are listed. One of the designs in the list could be chosen depending on the experimental budget restriction. Conclusion: The designs with box points replications are more efficient than those with the star points replication. The sequential method to establish a design space is illustrated with the simulated data based on the two examples in RSM.

The purpose of this research is to suggest diverse directions for eco-friendly knit designing through analyzing the characteristics of Stella McCartney's knit designs. The first stage of the research was to explore the characteristics of eco-friendly fashion design based on literature review. The next stage was to categorize the characteristics of eco-friendly design found in Stella McCartney' knit fashion based on the precedent analysis. The data collected showed 274 examples from 40 Stella McCartney collections, including Spring, Resort, Pre-Fall, and Fall Ready-to-wear collections between 2013 and 2022. All information was collected using www.vogue.com. As a result, the characteristics of Stella McCartney's knit design were classified into four directopms: 1) Perpetual Naturalism, 2) Cultural Complexity, 3) Practical Functionality, and 4) Subcultural Reproducibility. The first characteristic, 'Perpetual Naturalism' values the continuous symbiosis between animals and human beings, thereby protecting global environmental value. Stella McCartney's knit design continuously showed a longing for nature's beauty through fashion design, which allowed people to enjoy the meaning of symbiosis between human beings and animals. Second, 'Cultural Complexity' is the characteristic that appears in Stella McCartney's knit fashion design when collaborating with various artists and/or mixing traditional knit motives inspired by traditional cultures and retro moods. Third, 'Practical Functionality' is the design characterisitic that allows items to be worn for a long time as it is comfortable, simple, and practical. Stella McCartney's knit designs pursue easy-to-wear designs that are comfortable and have practical designs with simple details. Lastly, 'Subcultural Reproducibility' showed in Stella McCartney's knit designs reflect Hippie culture, which pursued a rejection of conventional values, and promoted sustainable energy. This culture peaked in the 1960s and 1970s, when 'Beatles' were mainly working. Additionally, retro styled knit designs inspired by other various music genres from the 1980s and 1990s appeared in this category as well.

The development of Korean textile industry has continued for the early industrialization. But a change in situation of circumstances, textile industry undergoes hard times. To overcome the barrier, therefore, technical development and design innovation are needed to make high value added product. This paper try to put to practical use of the silk weighting process technique(WPT). First, we investigate the technical trend of WPT to summarize the theory, and examine the feasibility of technical development. Second, the application of Graft process to silk textile is examined to know whether it is possible as an practical use. Next, we present the practical way of WPT using MAA monomer through experiment. The results are as follow. 1) Considering the lack of silk yarn. Graft process is appropriate new technique to make the value added product, and fine quality. 2) Studing textile goods, it need inter-displlinary co-work not only fiber engineering scope because textile goods is closely related with fashion industry. 3) MAA monomer used in this paper is more excellent then other monomer because it has good weighting effect and does not harm to the nature of textile. 4) MAA WPT is good for silk textiles of ladies jacket and neck-tie.

This article presents the design, control, and implementation of a small quad-rotor system under the practical limitation of being cost effective for private use, such as in the cases of control education or hobbies involving radio-controlled systems. Several practical problems associated with implementing a small quad-rotor system had to be taken into account to satisfy this cost constraint. First, the size was reduced to attain better maneuverability. Second, the main control hardware was limited to an 8-bit processor such as an AVR to reduce cost. Third, the algorithms related to the control and sensing tasks were optimized to be within the computational capabilities of the available processor within one sampling time. A small quad-rotor system was ultimately implemented after satisfying all of the above practical limitations. Experimental studies were conducted to confirm the control performance and the operational abilities of the system.

Multidisciplinary design optimization based on independent subspaces (MDOIS) is a simple and practical method that can be applied to the practical engineering MDO problems. However, the current version of MDOIS does not handle the common design variables. A new version of MDOIS is proposed and named as MDOIS/2006. It is a two-level MDO method while the original MDOIS is a single-level method. At first, system analysis is performed to solve the coupling in the analysis. If the termination criteria are not satisfied, each discipline solves its own design problem. Each discipline in the lower level solves the problem with common design variables while they are constrained by equality constraints. In the upper level, the common design variables of related disciplines are determined by using the optimum sensitivity of the objective function. To validate MDOIS/2006, mathematical problem and NASA test bed problem are solved. The results are compared with those from other MDO methods. Finally, MDOIS/2006 is applied to flow patterner design and shows that it can be successfully applied to the practical engineering MDO problem.

In recent years, in order to enhance the problem-solving skills required by the industrial field, universities have introduced the Problem-Based Learning(PBL) method to solve the problems caused by the lack of creativity, problem solving ability and self-directed learning. This study applied PBL class methods such as 'learning based on individual specific problems', 'self-directed learning', and 'small-group learning of small members' to practical design of fashion design. To do this, I conducted a questionnaire after conducting research based on the PBL module for one semester in a practical class of fashion design major at P University. As a result of the survey, the satisfaction and achievement of the class conducted by PBL learning method was improved than the existing teaching method. As such, if PBL class is used as a way of solving problems through close communication between professors and learners, it is expected to be established as a learner-centered education method that can improve creativity and professionalism.
