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.

최근 홈 쇼핑 이용자의 수가 급증하면서 각 매장에서는 소비자의 눈높이에 맞는 서비스를 제공하기 위한 많은 노력들이 있어왔다. 특히 의류 관련 매장에서는 온 오프라인에서 소비자들의 취향에 맞는 의상들을 실시간으로 체험해볼 수 있는 증강현실 기술 기반의 가상 피팅룸에 대한 연구가 진행되어왔으며 일부에서는 이미 서비스를 진행하고 있다. 이를 위해서는 일반적으로 OpenCV, 증강현실용 API 및 Kinect 등과 같은 시스템을 사용하여 사용자 인터페이스를 구축한다. 그러나 장비가 고가라는 단점을 가지고 있다. 그러므로 본 논문에서는 일반 가정에서도 특별한 장비 없이 쉽게 시뮬레이션해볼 수 있는 OpenCV 및 libsigc$^{++}$을 사용한 증강현실 기술 기반의 3D 가상 피팅룸 시뮬레이터를 개발한다. 본 시뮬레이터는 홈 쇼핑뿐만 아니라 온 오프라인 매장에서 매우 효율적으로 사용할 수 있을 것으로 판단된다.

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.
