This study is to compare the pattern making methods of men's jeans and to analyze sizes of parts while also evaluating the appearance and fit according to a 3D virtual garment simulation. Five types of patterns are selected for the analysis. For the appearance evaluation, the study conducted a virtual clothing simulation, created a perspective drawing, and applied Clothing pressure to each test outfit. First, according to the pattern comparisons, A and D had the shortest crotch length, while B had the longest; B had the narrowest crotch width, while C had the widest; C had the greatest waist circumference, and B had the smallest; C had the greatest knee and hem circumference, while E had the smallest. Second, according to the appearance evaluation, E pants had the highest rating overall for the waist, crotch, knee, and hem comfort; A pants had the highest rating for the yoke line end and placement; and C pants had the highest rating for the side seam line. According to the correlation analysis, ease of the waist, hips, hem and thighs were important factors (in that order) in determining the overall appearance of the jean pants.

Purpose: This study aims to understand the online practice experience of nursing students through virtual simulation in order to prepare basic data for online practice program development. Methods: This study is a descriptive study that applied a qualitative thematic analysis method to explore the online practice experiences of nursing students. It was targeted to 16 students in the department of nursing at a university. Results: As a result, 5 themes such as 'Feeling ambivalent about the online practice', 'Doubts about the effectiveness of online practice', 'Running into the limits of online practice', 'Feeling like a virtual simulation as an alternative', and 'Approaching true nursing' Conclusion: Virtual simulation is considered a very effective online practice program. However, since the lack of various scenarios and cases is pointed out as a limitation, it is necessary to develop and apply more diverse and systematic practice programs in future research.

This paper presents the effects of a virtual mass on the stability boundary of a virtual spring in the haptic system with first-order-hold. The virtual rigid body is modeled as a virtual spring and a virtual mass. When first-order-hold is applied, we analyze the stability boundary of the virtual spring through the simulation according to the virtual mass and the sampling time. As the virtual mass increases, the stability boundary of the virtual spring gradually increases and then decreases after reaching the maximum value. The results are compared with the stability boundary in the haptic system with zero-order-hold. When a virtual mass is small, the stability boundary of a virtual spring in the system with first-order-hold is larger than that in the system with zero-order-hold.

In this paper, we propose a system to a criminal profiling simulation training and assessment with virtual reality technology. Profiling has emerged as the incidence of violent crime has increased by 45.2 % in the country over the past decade. However, the number of profilers in Korea is 36, due to the problem of existing courses. "Criminal Reproduction Learning" is the common way to profiling training, but there are numerous constraints that prevent practical training. Thus, the system used virtual reality technology to overcome existing constraints. Users can receive simulation training and assessment of profiling at crime scene that have been implemented as virtual reality, with an immersive experience through interaction. We expect this system to contribute to the activation of profiling education in many institutions and to the development of good profilers with diverse training.

This research examines the possibilities of a traditional costume revival and digital exhibition as well as the application of 3D virtual clothing modeling data in order to preserve and record a disappearing costume heritage to realize it as a social education tool through the newly emerging technology of 3D virtual clothing. A 3D revival of costumes worn by royal families and aristocrats was accomplished through the 3D animation and simulation technology of Maya 2011 (Autodesk, Inc.) and Qualoth (FX Gear, Inc.). The simulation shows the possibility of a 3D revival and digital exhibition of costume heritage. However, further technology support to analyze and realize the composition and design is still necessary to develop the digital contents of traditional garment culture that includes skirt pleats, petticoat silhouettes, that exaggerates the skirts and knots of traditional upper garments (Jeogori). Further studies on design attributes of historic costumes and the upgrading of 3D simulation software are required to realize 3D virtual clothing. Korean traditional costumes will be revived as a cultural content in the digital era as a result of outstanding issues detected by this study.

This study is a descriptive qualitative study to understand the virtual reality-based simulation experiences of nursing students. The study recruited 53 students who conducted virtual reality-based simulation while attending the course of Adult Nursing I and II in the third year of the department of nursing at a university. The data was analyzed using a content analysis method from a reflection journal created anonymously by students. The results emerged 5 categories and 12 subcategories. The categories were consisted of "realizing the necessity of nursing competence", "expanding nursing knowledge", "receiving safety psychologically", "thinking focused on problem" and "getting satisfaction". It suggests that virtual reality online program can have a positive effect on thoughts and expansion of knowledge in a safe educational environment. Therefore, it needs to develop various contents for the virtual reality education and training.

Recently, the fashion industry has been integrating with The IT industry in order to develop in various ways. This study looks into ways to utilize the 3D CAD system, which would reduce time and cost while producing samples, and strengthen the communication between the brand and its cooperators by deploying knit designs using Knit CAD system's 3D virtual clothing program. The research method was reference, Internet resources 3D fashion CAD system and 3D Knit CAD system. Based on the data, simulation of the complete design of 4 deployed knit designs was done by using 3D virtual clothing program of the Knit CAD system utilizing knit design elements. One of each design element among the virtual clothing designs was chosen to produce real clothing, and the experts did verification on the appearance assessment of 3D virtual clothing knit designs of the Knit CAD system. As a result, 3D virtual clothing knit design of the Knit CAD system proved itself as an efficient system in terms of time and cost.

In this paper, we explore the issues of force display in the cooperative virtual environment shared by multiple users distributed over the network with heterogeneous hardware platforms. The proposed method is to cope with the problem of small time delay and the difference of sampling rate in the distributed configuration. In the proposed approach the interaction forces of the participants are just treated as the independent sources of acceleration. Thus the action of a participant simply changes the acceleration of the virtual object and consequently the states of the virtual object will be updated. When the updated states are reported to all the participants, the information on the time of state changes is delivered, too. Employing the discrete state information updated by the other users, each user modifies his own virtual environment and pseudo-realtime simulation can be realized. Excluding the software interface and the communication technique, it is proposed the simulation method for the operation of respective users and the way of calculating the driving input to the display device. For experimental verification we construct a cooperative virtual environment shared by two remote users and outline the results of experiments.
