Advances in IT technologies are developing VR content technologies that provide five senses information to users and interact with them. These VR content technologies are widely used by users not only for time and space limitations but also for providing immersion experiences. VR contents are contents that allow users to experience images that are played on the screen through five senses such as augmented reality, virtual reality, and holograms as well as visuals. VR games are also becoming more diverse in interfaces for the interaction of users with VR games. This study recognized the importance of the interface and analyzed the impact of the application characteristics of VR game UI on user experience and satisfaction from the user perspective. Research shows that VR game UI interacts with user experience and satisfaction. This appears to affect user experience based on how well people using VR game UI can understand and utilize the characteristics and functions of UI.

The purpose of this study is to explore the interaction of virtual reality consumption pattern under the background of virtual reality, and the influence of such interaction on consumers' purchase intention. In this paper, we selected three independent variables (including content interaction, function interaction and service interaction) and two mediating variables (including perceived quality and perceived value) to explore the relationship between them and consumers' purchase intention, used SPSS24.0 and AMOS24.0, made the analysis of reliability and validity, constructed the structural equation model, and tested the hypotheses. The findings show that: fourteen hypotheses are all true, and the perceived value of virtual reality has a positive influence on consumers' purchase intention. In addition, we find that the perceived value has a mediating effect in this study.

언어 연구에 관한 방법론은 단위구조적(modular) 접근방법과 총체론적(holistic) 접근방법으로 대별될 수 있다. 전자는 인지체계가 독자적 인지단위로 나뉘어져 있으며 그 중 하나가 언어기능임을 가정하고 있다. 즉 언어는 언어기능과 여타 인지단위로 상호작용함으로써 성립된다고 가정하는 것이다. 이에 비해 후자는 언어가 총체로서의 인지체계의 소산임을 가정하며, 따라서 언어기능이란 존재를 부정한다. 이러한 총체론적 언어이론에서는 신체의 구조가 보이는 단위구 조성과 심적 수조의 총체성 사이의 "불균형"을 어떻게 설명할 것인가의 의문이 제기된다. 이 글에서는 단위 구조설의 내용이 간략히 소개된다. 언어기능을 이루고 있는 보편문법 및 개별문법의 개념이 논의되는 가운데, 과거에도 그랬고 현재에도 계속 논란의 대상이 되고 있는 이른바 "문법성"의 개념이 중점적으로 다루어진다. 문법성과 허용성이 별개의 개념일진대, 문법적이면서도 허용되지 않은 문장이 있을 수 있고, 비문법적이면서도 허용되는 문장도 있을 수 있어야 한다. 이 후자의 경우도 실제로 존재함이 보여질 것이다.

The function of the [4Fe-4S] cluster containing iron (Fe-) protein in nitrogenase catalysis is to serve as the nucleotide-dependent electron donor to the MoFe protein which contains the sites for substrate binding and reduction. The ability of the Fe protein to function in this manner is dependent on its ability to adopt the appropriate conformation for productive interaction with the MoFe protein and on its ability to change redox potentials to provide the driving force required for electron transfer. The MgADP-bound (or off) conformational state of the nitrogenase Fe protein structure described reveals mechanisms for long-range communication from the nucleotide-binding sites to control affinity of association with the MoFe protein component. Two pathways, termed switches I and II, appear to be integral to this nucleotide signal transduction mechanism. In addition, the structure of the MgADP bound Fe protein provides the basis for the changes in the biophysical properties of the [4Fe-4S] observed when Fe protein binds nucleotides. The structures of the nitrogenase Fe protein with defined amino acid substitutions in the nucleotide dependent signal transduction pathways of the Switch I and Switch II have been determined by X-ray diffraction methods. These two pathways have been also implicated by site directed mutagenesis studies, structural analysis and analogies to other proteins that utilize similar nucleotide dependent signal transduction pathways. We have examined the validity of the assignment of these pathways in linking the signals generated by MgATP binding and hydrolysis to macromolecular complex formation and intermolecular electron transfer. The results provide a structural basis for the observed biophysical and biochemical properties of the Fe protein variants and interactions within the nitrogenase Fe protein-MoFe protein complex.

The drastically changing society has brought diverse types of families, and these diversities are changing the concept of the word 'family' itself. Inevitably, these changes cause different viewpoints among family members, developing into conflicts and social issues. In this paper, generational family problems, which are caused by changes within the family as a result of the variously, diversely changing society, are observed to suggest a resolution. Looking into the functional variety that today's structural change within a family demands, several positives changes described below have been observed; Firstly, the change in the way of interaction among family members; Secondly, the demand for continuance on relational functions including love, care, etc, as a psychological resource of family; Thirdly, the conversion from form's sake relationship to actual relationship; and Lastly, the usage of a clearer communications network. The interaction between the parent-children relationship, according to the changes in family life cycle, is also re-focused to seek resolutions for intergenerational conflicts. The results are as follows; Firstly, the changeability of various family types today must be accepted, and the functional aspects of changing families must be emphasized ; Secondly, the mutual-exchanging value of each generation must be accepted, strengthening relational functions between generations; Thirdly, it is necessary to refocus filial piety. In other words, though the intergenerational transmission of family functions may become the basis of lineage and clan formation, it won't be possible without interaction between generation.

Recently, interests on e-book (electronic-book) have been increasing since e-book can provide many benefits than traditional books can do. Especially, e-book can be attractive for elementary school students due to its interaction provided by various multimedia tools. However, despite the fact that the numbers of elementary school students using e-book have been increasing, researches on e-book have not made a significant progress. Also since most researches on e-book have been concentrating on fairy tale books without considering interaction, the true virtue of e-book has not been maximized. Taking this into account, this study is intended to suggest an e-book design model for elementary school students with interaction among learners reinforced. In this study, first, existing e-book design models are analyzed in terms of interaction. Based on this analysis, an e-book design model is designed and developed. The proposed model can help learners interact within their learning levels, support with many functions such as interchangeable help function, various search instruments, previews, messenger functions, and provide a book-like environment where learners themselves can take initiative in learning.

This paper attempts to elaborate on features of cross-border interaction conducted on Dan-dong, the main city of China-North Korea trade. Through the deep interview with some trader or firms and also questionnaire survey, this paper can reveal the supremacy of informal or non-market mechanism in the cross-border trade and inter-firm linkages, and also trader and firm's rent-seeking behaviour. These features show the uniqueness of border regime between China and North Korea. Even though it is getting more porous than before, I argue that China keeps the stance toward quite controlled borderland. As the proof of this argument, I show that main tenet of China's bordland policies is the borderland stability rather than the development. The striking one is the 'Prosperous Borders, Wealthy Minorities Program(??富民行???)'. In spite of the program's title, its utmost purpose is to secure the 'borderland stability and territorial integrity' rather than to enhance the border's openness and borderland's development.
