Purpose: This study aimed to investigate the effects of virtual reality used in maternal-child nursing clinical practicums on nursing students' competencies through a systematic review. Methods: The inclusion criteria were peer-reviewed papers in English or Korean presenting analytic studies of maternal-child nursing practicums using virtual reality. An electronic literature search of the Cochrane Library, CINAHL, EMBASE, ERIC, PubMed, and Research Information Sharing System databases was performed using combinations of the keywords "nursing student," "virtual reality," "augmented reality," "mixed reality," and "virtual simulation" from February 4 to 15, 2022. Quality appraisal was performed using the RoB 2 and ROBINS-I tools for randomized controlled trials (RCTs) and non-RCTs, respectively. Results: Of the seven articles identified, the RCT study (n=1) was deemed to have a high risk of bias, with some items indeterminable due to a lack of reported details. Most of the non-RCT studies (n=6) had a moderate or serious risk of bias related to selection and measurement issues. Clinical education using virtual reality had positive effects on knowledge, skills, satisfaction, self-efficacy, and needs improvement; however, it did not affect critical thinking or self-directed learning. Conclusion: This study demonstrated that using virtual reality for maternal-child nursing clinical practicums had educational effects on a variety of students' competencies. Considering the challenges of providing direct care in clinical practicums, virtual reality can be a viable tool that supplements maternal-child nursing experience. Greater rigor and fuller reporting of study details are required for future research.

Game industry has been grown up with invigorating online game since 1990s and increased in the spending side by focusing on commercial business. Game, however, has displayed a role that can producing cyber culture with Machinima that is a kind of movie made by a game engine. It should be discussed that non-linear activity of game is disclosed being closely connected with the environment of online space. Accordingly, there are three ways for this study. The first, characteristics of game environment taken non-linear effect related to hypertext space is researched. The second, Machinima is discussed as expansion of hypertext literature. And the last, considering game as consumption of just playing, game is able to become the subject role that can create virtual culture with making a variety of Machinima. consequently, through dichotomy and a liner form between consumption and production in hypertext space leaded to non-liner situation, positive and active features of game that has taken the activity of virtual reality into the multimedia literature would be delivered.

This study aimed to examine the impact of virtual influencers' characteristics on purchase intentions through attitudes toward the influencer and the brand, and to identify which factors are important depending on involvement. We used a scenario-based online survey of 320 female consumers in their twenties and thirties, and analyzed their responses through structural equation modeling using AMOS 21.0. Virtual influencers' attractiveness, reliability, familiarity, and virtuality had significant effects on consumers' attitudes toward those influencers, while their attractiveness, familiarity, and virtuality had significant effects on consumers' brand attitudes. Notably, in contrast to the other variables, virtuality had a negative effect. In addition, consumers' attitudes toward the virtual influencer significantly affected their brand attitudes and purchase intentions. We also analyzed which characteristics had significant impacts on high- and low-involvement groups. We found that reliability had the greatest influence on purchase intentions in the high-involvement group and that familiarity had the greatest influence on purchase intentions in the low-involvement group, which confirmed that the variables affecting purchase intentions differ depending on the level of involvement.

This study aims to compare the ease of shirt patterns in the men's wear market that have been constantly developing, and to analyze the fitness and appearance through the 3D virtual try-on system. The study selected three industrial patterns and two educational materials of classic-fit and slim-fit shirts for a total of ten items. The experiments involved virtual wearing, a stress contact point perspective map, and appearance evaluations. First, the ease differed significantly in the chest, waist, and sleeve cap height according to the patterns. Second, based on the stress, contact point, and transparency, there was ease in the order of Nam, D-brand, J-brand, Park, and S-brand in the classic-fit shirts while the order of D-brand, Nam, J-brand, Park, and S-brand resulted in the slim-fit shirts. Third, in the appearance evaluation, higher points resulted in the order of J-brand, Park, S-brand, D-brand, and Nam in both classic-fit and slim-fit. The results showed that proper ease differs greatly by shirt-fit and target age. Also, the shirts with more ease tended to be evaluated less favorably in the appearance evaluation. Based on the results, the study suggests that the proper ease in chest circumference is 18cm for the classic-fit shirts and 6 cm for the slim-fit shirts.

This study focused on the movement adaptability of $19^{th}$ century classical opera stage costumes. Researchers focused on a basic $19^{th}$ century women's jacket. The study analyzed movement adaptability using ROM (range-of-motion) tests of the upper limb flexion and abduction postures. It developed two research garments to mimic basic $19^{th}$ century style jackets with or without gussets at the axilla. The ROM experiment identified the gusset size as 11cm in length. Experimental postures included upper limb flexion and abduction. The study measured subjective comfort at 8 postures. These postures included the flexion and abduction of the arms and torso. Subjects also evaluated the subjective comfort of the rotation posture of the torso. Researchers evaluated the similarities between research garments' silhouettes and the $19^{th}$ century women's jacket. The study used a 3D virtual fitting system to evaluate fit, and specialists further analyzed fit with photographs and 3D virtual graphics. The results are as follows. The silhouettes of both research garments were similar to the silhouettes of the $19^{th}$ century western women's jacket. The jacket with axilla gusset had a better fit than the basic style jacket. The basic style jacket without the axilla gusset showed limited movement adaptability at the shoulder joint and it caused discomfort at the axilla and elbow. The 3D virtual fit test was not a suitable method for analyzing silhouette similarity.

The goal of this study was to develop a haptic communication system that can convey the tactile sensation of fashion materials in a virtual environment. In addition, the effectiveness and how realistically the virtual fabric image of this system delivers the tactile sensation of actual fabric was verified. First, a literature review was conducted through which the tactile attributes of fashion materials were defined that would be implemented in the haptic communication system. Then, a questionnaire for evaluating the tactile attributes of fashion materials was developed. Next, a haptic communication system was designed to convey fashion image experiences in a virtual environment, from which a haptic rendering model was suggested. The effectiveness of the haptic communication system was evaluated by verifying user experiences with questions developed through a user evaluation experiment. The validity of the evaluation questions pertaining to the tactile attributes and the effects of the haptic communication system were verified. Factor analysis was conducted to verify the evaluation of the tactile sense attributes of the fashion material, which identified density, thickness, and elasticity of the material as key factors. As a result of comparisons between the tactile sense through haptic characteristics and through touching, it was observed that regarding density and thickness, tactile sense experience led to greater perceived reality, while this was not the case for elasticity.

This study did a comparative analysis on the patterns of several male bodice slopers, followed by evaluating the appearance through a virtual garment simulation, which used a three-dimensional virtual garment system. Through this process, this study attempted to comparatively analyze the suitability of the garment or each sloper according to body parts. The analysis of the drawing formulas of bodices slopers had the following results. With a standard chest size, all six slopers had a 1:4 ratio for a front and back chest size; 1:5 or 1:6 for a front and back breast size 1:5 or 1:4 for a neck base circumference; and 1:20 or 1:12 for the chest size. When comparing the anthropometric figures and the actual measurements of each body part for the bodice slopers, the actual measurements secured extra amounts in the drawing process. The evaluation results for appearance of the six men's bodice slopers showed that the slopers used by companies (E and F) had top scores followed by the slopers made for (C and D), while the sloper for education (A) received the lowest scores. Regarding the results of the variance analysis verifying the significant difference between the slopers, twenty-five items had significant differences with the exception of four items on the front side and one item on the backside.

The Ministry of Education announced plans to introduce SW education to elementary and secondary schools in the 2015 curriculum. However, if we examine major foreign countries where SW education strongly implemented it is found that they stress not only coding education but also real life SW education. Especially they emphasized convergence with other different fields. Therefore, it can be concluded SW education in Korea should be differentiated based on levels of students. For the common basic curriculum, it is needed basic concepts and thinking skills of SW development, but for the enriched curriculum, it should be emphasized SW development education that can be applied to real life experiences and other difference fields as well. Therefore, it is necessary to plan SW intensive education to develop programs for the enriched program. In this study, I explored how virtual reality programming education can be applied to the level of elementary and secondary school students as an enrichment program.
