PURPOSE: This study examined the effects of posture improvement exercise using virtual reality programs on the posture and balance of patients with forward head postures. METHODS: Thirty men and women in their 20 s, who had a forward head posture, were divided randomly into a group with posture correction exercise and a group with posture correction exercise combined with virtual reality programs. The posture correction exercise was composed of squats, XCO training, and chin-tuck exercise. In contrast, exercise with virtual reality games involved the Hot Squat, Climbey, and Baskhead programs while wearing a headset. Both groups performed the exercises 15 min a day, three times per week, for four weeks. The balance ability, distance between the acromion and earlobe, and neck joint range of motion were assessed before and after the exercises. RESULTS: Both groups showed significant reductions in the distance between the acromion and the earlobe, along with significant improvements in the range of joint motion. The group that performed the virtual reality exercises showed a significant increase in the limit of stability. Both groups showed a significant decrease in the sway length. In contrast, the group given the virtual reality exercises showed a significant reduction in the sway speed while standing with their eyes closed. CONCLUSION: Exercise applying virtual reality programs can be used in clinical and home programs to correct the postures of individuals with a forward head posture because they can trigger interest in inducing active participation.

본 연구는 초등학교 과학수업에서 AR 콘텐츠 활용이 학습 활동에 미치는 효과를 알아보기 위해 AR 콘텐츠 적용집단과 전통적 집단과의 차이를 비교하였다. 이를 위해 학습 활동의 하위요소로 학습집중도, 학습활동 소요변인, 학습참여의 능동성, 수업분위기의 네 영역에서의 효과를 검증하였다. 그 결과, 학습집중도는 AR과 전통적 집단간에 의미있는 차이가 발생하지 않은 반면 학습참여의 능동성은 행동적인 능동성 요소에 있어서 AR 적용 집단이 높았고 언어적 능동성은 집단 간 차이가 발생하지 않았다. 학습활동 소요변인 측면에서는 AR 집단이 전통적 집단보다 학습자의 다양한 학습활동을 촉진하였다. 수업분위기 측면에서는 AR 콘텐츠 활용수업이 전통적 수업에 비해 수업분위기를 긍정적으로 조장하는 것으로 나타났다. 따라서 AR 콘텐츠를 과학과 수업에 적용하면 교수 학습과정에서 학습자의 행동을 능동적으로 촉진하고, 다양한 학습활동을 촉진하며 수업 분위기를 긍정적으로 조장할 수 있는 것으로 나타났다.

Purpose: Virtual reality's impact on fashion distribution extends beyond singular transactions, facilitating the emergence of novel collaborations. As investigating the characteristics of fashion distribution channels in virtual reality, this study explores how the fashion industry can utilize virtual reality distribution channels to their maximum capacity while minimizing potential disadvantages. Research design, data, and methodology: The approach used to gather previous studies for this study adheres to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. This method is widely acknowledged and recommended for its systematic and transparent approach to selecting relevant literature. This kind of literature search plays a vital role in a systematic evaluation as it informs the results. Results: The finding indicates consistently a total of eight kinds of characteristics of fashion distribution channels in virtual reality. The result means that the attributes of fashion distribution channels in virtual reality are causing significant changes in the fashion industry, revolutionizing the consumer experience, and redefining the parameters of creativity and collaboration. Conclusions: In sum, the global reach and accessibility of modern technology enhance the capacity of fashion companies to expand their market presence. This facilitates their participation in intercultural interactions and allows them to serve a wide range of customers.

In recent years, virtual reality (VR) technology has been widely used in many industrial fields, especially in the fields of medical treatment, games, film and television, to improve the interaction between medical teaching and practical treatment. On the gaming side, the production of virtual reality gaming screens and scenes became increasingly popular, greatly expanding the form of the visual experience. But VR is no longer confined to the health care, education and entertainment industries. During this time, the news media industry has also begun to integrate virtual reality into interviews and user interactions. This study aims to analyze the development of VR technology from the perspectives of immersive VR news experience, real reporting, and prospects, and analyze and think about the interactive participation of media users, the transformation of traditional media, and the upgrading of practitioners' roles.

Purpose: The purpose of the study was to provide deep understanding of the reported experiences of families with their loved one in the intensive care unit (ICU), focusing on interactions with healthcare providers. Methods: The data were collected by individual interviews of eleven participants. The transcribed data were analyzed using qualitative content analysis to identify major themes and sub-themes that represented the experiences of families. Results: Five themes and 13 sub-themes emerged. "Captive of patients' delayed death: Fear and anxiety" describes psychological problems arising when the family member became critically ill enough to warrant being admitted to the ICU. "Families as the weak: Suppression and resistance" describes interpersonal difficulties arising due to lack of information and trust with healthcare providers. "Deprivation of authority and duty as families: Helplessness" illustrate situational barriers in attempting to protect and support family member. "Re-establishment of trust relationship with healthcare providers: Gratitude and appreciation" describes how they satisfied with themselves by regaining trust relationship. Lastly, "Acceptance of reality through direct care participation: Relief and peace" illustrates peace of mind by gaining sense of reality through active direct care participation. Conclusion: This study demonstrates the positive and negative experiences of families with ICU patients. The results will be useful in developing family-centered nursing interventions.

Purpose: The purpose of this study was to explore perception of clinical experience between the initial and final practice and to explore changes in the perception of clinical experience. Method: The study used a Q-method to measure perception of clinical practice. Thirty-six statements made up the finalized Q-sample. The P sample used thirty three nursing college students from K university. The initial collection was done in the first semester of their junior year and second collection was done in the last semester of their senior year. The Q-sorts by each student were coded and analysed with the Quanl PC program. Result: Many students classified as having the perception type 'alienation of ideal and reality' or 'perception of limitation of ability' in the initial clinical practice changed to the type, 'active participation' by the final clinical practice. Further, in the initial clinical practice, part of 'active participation' and 'perception of limitation of ability' changed to 'alienation of ideal and reality'. Conclusion: This study shows that perception of their clinical practice by student nurses changed in a positive direction through clinical experience and that this fact was related to the level of satisfaction with nursing. The knowledge and understanding obtained in this research provide insights for nursing faculty and students involved in nursing education.
