VR은 가상의 콘텐츠를 시각, 청각 등 감각을 통하여 현실인 것처럼 체험하는 가상현실 기술을 말한다. VR은 발전을 거듭하여, 뉴스에까지 영향을 미치고 있다. 이는 뉴스의 틀을 크게 흔드는 것으로, 기존의 방식이 사진이나 기사, 영상을 보는 수동적 행위로 뉴스를 보는 것이었다면 VR 뉴스는 체험과 참여라는 능동적 패러다임을 제시하고 있다. 본 연구는 각 언론사들의 VR 뉴스를 분석하여 보고, VR 뉴스가 어떠한 방법으로 발전하고 있는지 살펴보았다. 나아가, 실제로 VR 뉴스에 대해 사용자들이 어떻게 인식하고 있는지 알아보기 위해 실험연구를 실시하였다. 뉴스를 이용하는 사용자들에게 기존의 방식과 VR 뉴스 방식으로 작성된 뉴스를 비교하여 보여주고, 질문지를 통해 인터뷰하였다. 통계 및 분석 작업을 통하여 도출한 결과는 다음과 같다. 사용자들은, VR 뉴스에 대한 인식에서 사실적인 현장감이 느껴지지만, 뉴스가 가지고 있는 고유한 정보 전달의 측면에서는 아직 부족하다고 평가하였다. 하지만, VR 뉴스에 대한 재이용 의사는 높게 나타났는데, 이는 VR 뉴스를 접해 본 사용자들이 갖는 기대감이 나타난 부분이다.

Background. Ischemic heart disease results from athesclerotic changes of the coronary artery. These changes are aggravated by hypercholesterolemia, smoking, obesity, lack of exercise, coronary-prone personality, and stress. Because these risk factors affect not only the prevalence of the ischemic heart disease but also recurrence of the disease, cardiac rehabilitation programs were introduced to help patients with ischemic heart disease reduce risk factors. Diverse cardiac rehabilitation programs are needed to motivate participation in cardiac rehabilitation and to enhance patients' quality of life. Objectives. To examine the effect of a self-efficacy promoting cardiac rehabiltation program on self-efficacy, health behavior and quality of life of patients with ischemic heart disease. Methods. Data were collected from 45 hospitalized ischemic heart disease patients. Medical records were reviewed to obtain demographic and clinical characteristics. Data regarding self-efficacy, health behavior, and quality of life were obtained from interviews using structured questionnaires. The nonequivalent control group non-synchronized design was used to conduct this study. One session of conventional group education was given to patients in the control group while they were in the hospital. Patients in the experimental group participated in a newly developed cardiac rehabilitation program. It focused on strengthening self-efficacy with four self-efficacy sources-performance accomplishment, vicarious experiences, verbal persuasion and physical status using two individualized in-hospital education sessions and four weekly telephone counseling follow-up calls after discharge. Results. Four weeks after discharge, the increment of total self-efficacy score was significantly higher in the experimental group than in the control group (p<.0l). There was also a significant difference in the total quality of life scores increments between the two groups (p<.0l). However, no significant changes were noted in the increments of total health behavior scores between the two groups. Conclusion. A cardiac rehabilitation program focusing on promoting self-efficacy was effective in improving self-efficacy, and quality of life of patients with ischemic heart disease.

'I'his study investigated students' attitude toward mathematics. and how behavior/cognitive training affects level of math anxietv and level of math achievement. Subjects were all the freshmen attending Taejon Science High School, and they were given Mathematics Attitudes Scale and Attributional Style Questionnaire prior to and post training sessions. Twenty out of 84 freshmen voluntarily participated in nine sessions of training program. Participants were asked to do self-evaluation. Math achievement was measured prior to and post training. and was compared between two groups. Training program utilized behavior/cognitive approach. such as understanding one's feeling through muscle relaxation, breathing and meditation; modifying negative attributional style; imitating effective cognitive strategies for math problem solving, and so on. 'I'he result shows that students' math confidence in general was relatively low out of expectation, a nd they perceived teachers not supporting their math abilities :IS much as expected. On the other hand, students in general had strong math achievelment needs, and considered math utility very high. Sex difference was seen in the attitude toward female math abilities, to result that female students had more positive perception than male students. Female students of 'I'aejon Science High School seem free from conventional idea about female abilities including theirs. Participants' ~attitude change was compared with non-participants. and participants showed statistically significant change in their math confidence, and also in their math achievement. Participants had much higher math confidence and ~achievement than non-participants. And, they showed increased level of perceiving teachers' expectation. more realistic in needs, and more involvement in math. Math achievement was found positively related to math confidence, and participants' math achievement change was explained by their belief in math utility. Not only training program effect hut also participants' voluntary involvement and teacher\ulcorner' support of the program and participation seem to increase their math achievement. Based upon the result of study it was suggested that behavior-/cognitive training program be provided along with academic curricula for gifted students of Korea to help their emotional and psychological development enhance the efficacy of their cognitive learning.

In existing method, research for landscape resource is driven by professional (or with the participation of local people at Tokenism level), and usually hinder local residents from reflecting their appreciations on the landscape resources in their own ways and eventually ends up with indistinguishable landscape planning. To avoid this, a profound understanding of what landscape they experience in their daily life and how they perceive it should be empirically analysed carefully. The purpose of this study is to apply walking behavior as a method to examine local residents' subjective perceptions and consider its usability. The researcher walked the site(Sucheongri) with the residents, carrying a GPS device, taking photographs of the landscape objects they described, and recording the relevant explanations. After gathering photographs and explanations which represent the research participants' individual subjective perception, the researcher analysed the explanation using open coding, based on grounded theory. By the analysis, 117 landscape objectives are identified and 18 reason factors for landscape perception were deduced from the explanation. Those factors could be classified as 'positive feeling inducing' and 'negative feeling inducing', and also as 'personal emotion based' and 'community based emotion'. By comparison between feeling map by conventional method and feeing map by new method, usability of new method was empirically reveled. Walking behavior makes it easier for researcher to get more abundant data in quantitative aspect and profound understanding with affection of respondent by allowing them to 'go beyond' the perceptions they remember. Finally new method with walking gives professionals a contextual understanding of a place and more resident-oriented plans and management on sites.

The article presents a theoretical-experimental approach developed for modeling the coefficient of sliding friction in the dynamic system tool-workpiece in slide diamond burnishing of low-alloy unhardened steels. The experimental setup, implemented on conventional lathe, includes a specially designed device, with a straight cantilever beam as body. The beam is simultaneously loaded by bending (from transverse slide friction force) and compression (from longitudinal burnishing force), which is a reason for geometrical nonlinearity. A method, based on the idea of separation of the variables (time and metric) before establishing the differential equation of motion, has been applied for dynamic modeling of the beam elastic curve. Between the longitudinal (burnishing force) and transverse (slide friction force) forces exists a correlation defined by Coulomb's law of sliding friction. On this basis, an analytical relationship between the beam deflection and the sought friction coefficient has been obtained. In order to measure the deflection of the beam, strain gauges connected in a "full bridge" type of circuit are used. A flexible adhesive is selected, which provides an opportunity for dynamic measurements through the constructed measuring system. The signal is proportional to the beam deflection and is fed to the analog input of USB DAQ board, from where the signal enters in a purposely created virtual instrument which is developed by means of Labview. The basic characteristic of the virtual instrument is the ability to record and visualize in a real time the measured deflection. The signal sampling frequency is chosen in accordance with Nyquist-Shannon sampling theorem. In order to obtain a regression model of the friction coefficient with the participation of the diamond burnishing process parameters, an experimental design with 55 experimental points is synthesized. A regression analysis and analysis of variance have been carried out. The influence of the factors on the friction coefficient is established using sections of the hyper-surface of the friction coefficient model with the hyper-planes.

Background and objective: Urbanization caused a reduction in urban green space and a lack of community spaces. An attempt to solve these problems, urban gardens, have become popular and are currently being implemented in various downtown areas. However, urban gardens have some inadequate aspects from a visual or landscape perspective. The goal of this study was to examine the possibility of an aesthetic and productive garden space by introducing cultivation methods through the planting system design process. Methods: The design process using plants was classified and presented to suggest the importance of the landscape and aesthetic value. An urban garden space was designed according to the perspective of 'production scenery' and 'participation aesthetics'. According to the characteristics of the plant, urban gardens were divided into vertical type (corn, millet, sorghum), climbing type (kidney bean, cucumber, bitter gourd), and runner type (melon, watermelon, peanut). After classifying plants according to the shape of the root, the structure supporting climbing was installed and the crops were cultivated in an upright form with a tunnel. Results: In the designed cultivation, each crop cooperates, without invading each other's space. Compared with the conventional cultivation, there was little difference in production, and management was made more convenient since weed outbreaks were effectively suppressed while runner type crops cover over the land's surface. Since the positions of each crop are clearly distinguished, the aesthetic value is improved by offering a sense of rhythm with a balanced design. Conclusion: The results suggest that the cultivation methods through the plant system design process have aesthetic as well as productive value, and the design using plants, an infinite living resource, could lead to an expansion of the design field. Moreover, it would enable a sustainable symbiosis between industry and environment. There is potential for the design industry to make significant progress through collaboration with agriculture, horticulture, and landscape architecture.

A injection mold usually requires 30 to 50 revisions, and as the number of revisions increases, the burden of increased costs, schedule delays, and decreased reliability increases, reducing the competitiveness of companies. In addition, these costs become a more serious problem when the customer is far away, which is an obstacle to the export of domestic mold companies with excellent technology. The objective of this study is to develop an augmented reality platform that will facilitate the sharing of realistic 3D virtual objects in real time and enable mold designers to collaborate using a range of tools in remote locations and virtual environments. The platform collaboration solution enables simultaneous participation and synchronization of design collaboration with four types of devices (PC, mobile, VR, and MR). The efficiency and precision of the high-speed injection molding analysis module were validated through rigorous testing, demonstrating a processing speed that ranges from 500 to 3,000 times faster than that of the conventional numerical analysis method, with a relative error of less than 15% and a service performance of more than 80 fps. The user-friendly and intuitive UI/UX was configured and the usability was verified through scenario verification.
