The purchase-related responses of MZ generation consumers may vary depending on the environmental factors of the fitting room. Therefore, this study extracted and systematized fitting room characteristics in the retail fashion environment. In-depth interviews were conducted with a total of 50 informants to collect data on the experience of using the fitting room. Then, a qualitative analysis was performed. First, results confirmed that the environmental factors of the fitting room include physical (spatiality, functionality, comfort, and convenience) and human (interactivity and congestion) aspects. Next, additional analysis was performed on functionality and interactivity to clarify the influence of environmental characteristics of the fitting room. These factors were classified into qualitative categories. The study results confirmed that, in the case of functionality, preferred lighting and mirror factors vary depending on the clothing product type, the place and situation for wearing, and individual characteristics. Furthermore, regarding interactivity, the preference for the presence of sales staff or companions differed according to personal traits and the need for additional information and evaluation. The study provides valuable information for effective fitting room space planning for offline fashion stores to meet the needs of MZ generation consumers.

There are three sub-processes associated with the assembly of the valve seat and cylinder head; heat fitting, cold fitting, and shrink fitting. In the heat fitting stage, the cylinder head is heated to a specified temperature and then squeezed toward the outer diameter of the valve seat. The cold fitting process cools the valve seat and safely squeezes it toward the inner diameter of cylinder head. However, these methods increased the installations & running cost and curtailed productivity. To address these problems, we analyzed the shrink fitting process using the contact pressure caused by fitting interference between the outer diameter of the valve seat and the inner diameter of the cylinder head. In this study, a closed form equation for predicting the contact pressure and fitting load is proposed. For quality control of the assembly line, principal factors of the shrink fitting process influenced in contact pressure were simulated by the FEM. Actual loads measured in the field showed good agreement with the results obtained by theoretical and finite element analysis.

Recent, the number of consumers using home shopping are in increase. So, there have been a lot of effort to provide services that meet the consumer's eye level in each store. In particular, apparel stores have been conducted the research for virtual fitting room based on augmented reality technology that consumers can simulate in real time costumes that meet the tastes of consumers in online and offline market. In addition, some services has already progress. The general virtual fitting room simulator built the user interface based on OpenCV, augmented reality API, Kinect, and so on. But, it has the disadvantage that the equipment is expensive. In this paper, we have developed a 3D virtual fitting room simulator based on augmented reality technology using OpenCV and libsigc$^{++}$. This simulator can simulate easily in general home without any special equipment. This simulator is expected to be available very efficient in online and offline market as well as home shopping.

In the era of COVID-19 and advanced ICT technology, retail technologies such as those that use virtual reality(VR) have been drawing significant attention in the fashion industry. This study investigated the impact of shopping motivation and telepresence on consumer attitude, trust, and behavioral intentions in VR fitting room application environments. An online survey was conducted on female consumers in their 20s and 30s after exploring a VR fitting room application. Overall, 225 responses were used for the analysis. The study demonstrated that usefulness had a significant effect on attitude toward product (ATP) and trust toward app (TTA), while enjoyment had a significant effect on ATP, but did not significantly affect TTA. Telepresence did not significantly affect TTA, but had a significant influence on ATP and behavioral intention. TTA had a significant influence on ATP, and both ATP and TTA had significant effects on behavioral intention. Moreover, the effects of usefulness, enjoyment, and telepresence on ATP, TTA, and behavioral intention were significant, as the self-congruity between consumers and avatars increased. The application of the motivation theory and technology acceptance model offers theoretical perspectives for understanding VR fitting room application users' attitudinal and behavioral responses in mobile shopping environments. In addition, this study provides practical implications to mobile retailers that utilize advanced technologies.

A fitting process carried out in the automobile transmission assembly line is classified into three classes; heat fitting, press fitting, and their combined fitting. Heat fitting is a method that applies heat in the outer diameter of a gear to a suitable range under the tempering temperature and assembles the gear and the shaft made larger than the inner radius of the gear. Its stress depends on the yield strength of a gear. Press fitting is a method that generally squeezes gear toward that of a shaft at room temperature by a press. Another method heats warmly gear and safely squeezes it toward that of a shaft. A warm shrink fitting process for an automobile transmission part is now gradually increased, but the parts (shaft/gear) assembled by the process produced dimensional change in both outer diameter and profile of the gear so that it may cause noise and vibration between gears. In order to solve these problems, we need an analysis of a warm shrink fitting process in which design parameters such as contact pressure according to fitting interference between outer diameter of a shaft and inner diameter of a gear, fitting temperature, and profile tolerance of gear are involved. In this study, an closed form equation to predict the contact pressure and fitting load was proposed in order to develop an optimization technique of a warm shrink fitting process and verified its reliability through the experimental results measured in the field and FEM, thermal-structural coupled field analysis. Actual loads measured in the field have a good agreement with the results obtained from theoretical and finite element analysis and also the expanded amounts of the outer diameters of the gears have a good agreement with the results.

With 100 collegians residing in Busan, a shoes wearing survey was held. Out of the subjects, 50 women collegians showing some interest in fashion sneakers were chosen to reveal the effects of shoes size changes on walking patterns and wearing sense. This study focused on the fitness of sneakers produced the following results: 1. Survey Results of Shoes Wearing The subjects had some room in wearing sneakers or athletic shoes, including $20{\sim}30mm$ (33%). Just 25% of the subjects reported about the experience of falling, and 67.6% had difficulty walking on downhills. 50% felt feet fatigue difference when wearing fitting and unfitting shoes. 2. Analysis of Walking Patterns & Survey Results of Wearing Sense No significance was found among shoes sizes in left and right step angles. Step width measurement revealed no significance among shoes sizes. Significance ($p{\le}.05$) existed among shoes sizes in steps and strides. Significance ($p{\le}.001$) was noticed among shoes sizes in wearing sense.
