Design changes frequently occur while design activities are performed. If the impact of design changes is estimated, design efficiency can be improved. But, the types of design changes are various and they can affect other design parts. Hence, it is difficult to deal with design changes directly. The purpose of this research is to develop systematic algorithms for change propagation tracing and change impact analysis, and then to implement a change impact analysis system. We have selected a process-based design and a design environment which is composed of design parameters and constraints. The algorithm for change propagation tracing tracks the change propagation of design parameters and finds design parameters, constraints and tasks which are probably changed. In the algorithm for change impact analysis, a change impact value is calculated from the list of changeable tasks. These two algorithms have been implemented into change impact analysis system (CIAS). CIAS has been applied to the redesign of 2 stage gear drives. CIAS can improve the efficiency of design activities. If there are many alternatives for a design change at the redesign step, designers can calculate the change impact value of each alternative and perform design change activities in the direction of minimizing design change impact.

In order to design a good ready-made cloth, it is important to consider not only body size but also morphological factor. However, most dissatisfaction of customer is focusing on the size of ready-made cloth which is graded with elements of body size. Various researches on body type have been doing but the study on part of body type is insufficient compared to the study on whole body type. The objective of this paper is to provide relationship of shoulder angle between value in pattern and real measured value after analysis and comparison with these two values.

Today, false news is increasing in volume, and fashion news often circulates uncritically. Therefore, an evaluation framework is needed to determine whether fashion news is accurate or good. In journalism, the judgment of good news is made through the criterion of news value factors. These factors are the criteria for assessing the likelihood of an event being reported in the news. Through the study of news value by various journalistic scholars, this study selected nine news value factors applicable to the value measurement of fashion news as the framework of analysis. Based on this, after analyzing the actual news on online fashion media, new characteristics and content were reconstructed for fashion news. As a result of the study, it was finally selected that the crucial factors were: expertise, social importance, timelessness, conflict, and negativity for measuring the value of fashion news. To assess the news value of fashion accurately, this study found that reconceptualized news values are needed, which are different from the news values of general journalism. The study is meaningful in that it explores elements and content for the development of a theoretical framework for the qualitative evaluation of fashion news.

In this paper, as a clean lift, a maglev(magnetic levitation) clean lift is designed and described. The maglev clean lift, which is superior to conventional lifts in vibration, noise, clean class and speed characteristics, consists of magnets, guide rails, guide rollers, magnet module frame, cage, guidance controller, sensors, etc. As design specifications, the maximum value of vibration is 0.2G, the maximum value of noise is 60dB, and the clean class is #10. The design results for the maglev clean lift are shown and discussed.

Currently, due to COVID-19, household waste has a lot of impact on the environment due to packaging of food delivery. In this paper, we design and implement Faster-RCNN, SSD, and YOLOv4 models for municipal waste detection and classification. The data set explores two types of plastics, which account for a large proportion of household waste, and the types of aluminum cans. To classify the plastic type and the aluminum can type, 1,083 aluminum can types and 1,003 plastic types were studied. In addition, in order to increase the accuracy, we compare and evaluate the loss value and the accuracy value for the detection of municipal waste classification using Faster-RCNN, SDD, and YoloV4 three models. As a final result of this paper, the average precision value of the SSD model is 99.99%, the average precision value of plastics is 97.65%, and the mAP value is 99.78%, which is the best result.

This study examines how the development and value of dresses shown in MBC historical dramas have changed with the overall change of the dramas. As for the research method, the second data analysis was done with literature study which was supplemented with interviews with the wardrobe team of MBC production design center. Historical dramas produced by MBC have gone through the developmental period, legitimate historical drama-oriented period, stagnant period, and historical dramas-modernized period. The value of costume in each period is as follows: Costume in the developmental period is considered only as part of drama setting. During legitimate historical drama-oriented period, it carries value as educational data and historical replica produced by historical research. Production design including costume obtains its own value in the stagnant period although the production of historical dramas decreases dramatically. And lastly, in the historical dramas-modernized period, costume starts to have commercial value as cultural contents. Historical drama costume may contain important value in terms of education and history, even though there has been controversy on TV historical dramas' role: they should focus on reproducing historical facts or they should support writers' creativity.

The purpose of this study is to closely describe the meaning of the clothing conformity behavior of female consumers in today's society. In this process, the vanity scale was used as a precedence variable, on the other hand, clothing consumption value and information search behavior was used as outcome variable, which has an effect on the clothing conformity behavior. The subjects were 300 females who live in Seoul and Kyung-gi. The data were analyzed by Cronbach's ${\alpha}$, Factor analysis, Regression and ANOVA using SPSS program. The results were as follows. First, the vanity scale was classified into four factors, a concern and a positive view for each achievement and appearance. Clothing consumption value was divided into five factors; fashion, appearance attractiveness, emotional, social and functional clothing consumption value. Clothing conformity behavior was classified into three factors; normal, informational, and identified conformity factor. Second, various vanity scales influenced the clothing conformity behavior factors. In particular, concern for achievement and appearance were more important factors to clothing conformity behavior. Among six clothing consumption values, fashion was a more significant factor affected by clothing conformity behavior. Also, various conformity behaviors influenced the information search behaviors. Finally, according to age, school record, and pocket money, there were significant differences in clothing conformity behaviors and vanity factors.
