Objectives : The objective of this study is to examine the experiences of Internet game experience targeting to University students in Korea. Research topics was "What is meaning of internet game to the University students?" Methods : Classical phenomenology underpinned this study. Seven qualitative studies of University students were conducted between 20 and 23 years old. Semi-structured interviews were conducted. Interviews were audio recorded and transcribed verbatim. Phenomenological thematic analysis of data was undertaken. Results : The findings pivot around three interconnected themes :[Expectations for the emotional needs], [Spend time in the cyberspace], [Relieve stress throughout the game], [Instead of satisfaction from virtual reality], [Internet gaming repeat and desires]. The basic need for getting into internet game was [satisfaction from virtual reality was identified]. While internet games was eliminated stress, [Expectations for the emotional needs] and [Spend time in the cyberspace] were the catalyst that makes them repeatedly getting into Internet the game. Based on the result, I suggest that Internet gaming should be recognized as a tool to relieve stress for college students, But it is not satisfied with the reality in virtual space. Therefore, the strategy must be to recognize reality accompanying. And Using a lot of time in cyberspace make them cause of internet game addiction. Therefore, it requires a systematic strategy for the Internet using time limits. Also the emotional needs met were motivated to repeat an Internet game. So another way to meet the emotional needs to college students should be sought.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

While online social interactions have been more prevalent with the increased popularity of Metaverse platforms, little has been studied the effects of facial expressions in virtual reality (VR), which is known to play a key role in social contexts. To understand the importance of presenting facial expressions of a virtual avatar under different contexts, we conducted a user study with 24 participants where they were asked to have a conversation and play a charades game with an avatar with and without facial expressions. The results show that participants tend to gaze at the face region for the majority of the time when having a conversation or trying to guess emotion-related keywords when playing charades regardless of the presence of facial expressions. Yet, we confirmed that participants prefer to see facial expressions in virtual reality as well as in real-world scenarios as it helps them to better understand the contexts and to have more immersive and focused experiences.

This narrative review explores the transformative potential of immersive virtual reality (IVR) in enhancing high school students' mathematics competence, viewed through the lens of the technological, pedagogical, and content knowledge (TPACK) framework. This review comprehensively illustrates how IVR technologies have not only fostered a deeper understanding and engagement with mathematical concepts but have also enhanced the practical application of these skills. Through the careful examination of seminal papers, this study carefully explores the integration of IVR in high school mathematics education. It highlights significant contributions of IVR in improving students' computational proficiency, problem-solving skills, and spatial visualization abilities. These enhancements are crucial for developing a robust mathematical understanding and aptitude, positioning students for success in an increasingly technology-driven educational landscape. This review emphasizes the pivotal role of teachers in facilitating IVR-based learning experiences. It points to the necessity for comprehensive teacher training and professional development to fully harness the educational potential of IVR technologies. Equipping educators with the right tools and knowledge is essential for maximizing the effectiveness of this innovative teaching approach. The findings also indicate that while IVR holds promising prospects for enriching mathematics education, more research is needed to elaborate on instructional integration approaches that effectively overcome existing barriers. This includes technological limitations, access issues, and the need for curriculum adjustments to accommodate new teaching methods. In conclusion, this review calls for continued exploration into the effective use of IVR in educational settings, aiming to inform future practices and contribute to the evolving landscape of educational technology. The potential of IVR to transform educational experiences offers a compelling avenue for research and application in the field of mathematics education.

Objective: The present study aimed to explore the experiences of mothers who have abandoned their additional birth plans since their first child was born. Methods: During in-depth interviews, mothers were asked to recall their own experiences of motherhood. The interview data were analyzed using the grounded theory. Results: The central phenomenon was 'The burden of raising a child is too heavy for mothers to carry alone.' The causal conditions were 'First experience: Unpredictable life', 'Physical and psychological difficulty', and 'Spouse's absence.' The contextual conditions were 'Expectations and reality of parenting' and 'Workplace conditions.' The mothers used interaction strategies of 'Defusing conflict only on a surface level: Giving up', 'Reliance on grandmothers', and 'Downgrading career aspirations.' These strategies were mediated by intervening conditions, 'Stereotypes and experiences of non-family nanny', 'Child's development', and 'Family conflict.' The results were 'Endless guilt', 'Ambivalence between independence versus interdependence' and 'Unfairness: Why only me?' Finally, the process of psychological conflict was identified to account for the steps leading mothers to give up on their birth plans. Conclusion/Implications: During the first experience of motherhood, mothers' conflict gets escalated despite their struggles. These experiences might discourage their additional birth plans. These results provide implications for policies to increase fertility rates.

Purpose: This qualitative study was designed to explore and describe the nursing staff reported experiences of managing the medical needs of nursing home residents in South Korea. Methods: Using a focus group interview method, qualitative data were collected from March to May 2012. Twenty five registered nurses and nurse aids working in nursing homes were recruited through a convenient sampling method. Participants participated in one of four focus group interviews lasted up to two hours in which their day-to-day experiences of taking care of the medical needs of the elderly residents. All interviews were recorded and transcribed in verbatim, and analyzed according to the qualitative thematic analysis method using MAXQDA software. Results: The overriding theme was 'experiencing differences between the requirements of the regulatory system and the actual reality of the work place.' The findings of differences between what were true and what is required was based in four subcategories. The nursing home residents had far more medical needs than what were reported. Another finding was that the family members were seen as non-supportive and negligent towards the residents. Conclusion: The findings of the study support the need for changes in the regulatory system. The regulatory limitations of current system with a shortage of resources pushed the participants to experience discrepancies between the required regulation and the reality. Additional research could contribute more exemplars to support changes.
