Background: A validation study is needed to make domestic applications of German Kneipp therapy. Purpose: The study aims to test the effect of a Kneipp therapeutic program in a domestic forest environment on the autonomic nervous system. Methods: The program was made considering the 4 key elements ('exercise', 'regulative therapy', 'nutrition', and 'phytotherapy') of the Kneipp therapy. Total 3 sessions (once a week for 5 hours in each session) were performed to 40 domestic adults divided into four groups (10 in each group). HRV was measured on the subjects before and after the intervention, and its 6 characteristic parameters (TP, VLF, LF, HF, LF/HF, CSI: Cumulative Stress Index) were compared for statistical analysis. Results: For 33 subjects excluding 7 who were disturbed by interrupt factors during measurements, significant improvements after the intervention, were observed in TP(8.64%, p < ..001), VLF(6.96%, p < .05), LF(15.86%, p < .001), HF(8.46%, p < .01), LF/HF(5.77%, p < .05) and CSI(-16.06%, p < ..001). Conclusions: The Kneipp therapy performed in the forest environment was shown to activate the autonomic nervous system and in particular the sympathetic and parasympatheric nervous to promote heart activity, and was also shown to most significantly reduce cumulative stress. The present observations would be the first preliminary evidence that the Kneipp therapeutic interventation in a domestic forest environment results in positive responses of the autonomic nervous system including stress relief.

HYBE Insight, opened in May 2021, is an exhibition space that visually displays and re-interprets the BTS Universe and its content. The space echoes the identity of BTS as an artist and the specificity of the cultural phenomenon they have generated. This study analyzes HYBE Insight's BTS exhibition by applying new museological theories and discourses. Based on a qualitative research methodology including literature review and observational method, the primary themes of the exhibition are follows: 1) a contextualized exhibition content presenting the identity of BTS and their music, 2) the role of the fandom Army's participation in (re) producing BTS content related to the characteristic of popular music museums, 3) the elements of convergence art and its contemporary implication, 4) and the illumination of cultural value in popular music museum management. As the pivotal theory of new museology suggests, investigating a specific exhibition based on each context it has created is significant. However, those studies, including exhibitions related to popular music/artists, were mostly developed in Western nations. In this respect, HYBE Insight's BTS exhibition provides considerable room to explore. In addition to the recent research on BTS, such as their convergent artistry, socio-cultural influence, the role of Army, and the characteristics of HYBE's content management, this article aims to contribute to the multifaceted research by scrutinizing the BTS exhibition content from the new museology perspective.

As the theme of a theme park space with limited space emerged as a keyword, many experiments and research were conducted in the field. In the domestic market, not only the creation of new spaces, but also the need to develop marginalized spaces and seek complementary points through new interpretations of actual spaces, but they show physical limitations. This study newly redefined and analyzed the concept of space by approaching and interpreting virtual space as a new space. By exploring real-world examples and analyzing the results, we also derive the results that the possibility of realistic media in the virtual world is an exemplary alternative to complementing the expansion and limitations of the space. Realistic media has a wide range of content provision in selective development such as AR and VR, and the theme park's characteristic of providing various contents for quarterly concepts even if the development budget and time are small, which has a significant impact on the development of realistic media. Currently, theme parks are attracting countless majors and officials related to realistic media through metaverse. As it is attracting attention in such a new market, we look forward to seeing a lot of research and experiments in the project.

In this study, the physico-chemical and biological characteristics of anaerobic granular sludge at different heights of a full-scale UASB reactor (UASBr) were investigated. Granular sludge was taken from 1 m, 2 m, and 3 m above the ground level in the UASBr. The morphological analysis showed that the upper part had bigger granules and the lower part had rounder granules. The ANOVA test confirmed that the mean size and the roundness of the granules had statistically significant difference along the height at 95% confidence level, and there was a significant negative linear relationship between the size and roundness (r=-0.40, p<0.05). A SMA test using acetic, propionic and butyric acids showed that granules from 2 m height had the highest specific methanogenic activity. The EPS contents were also unequal to each height, with 2 m showing the highest content. These findings could be helpful to understand the different characteristics of stratified anaerobic granules in full-scale UASBr and maintain the reactor performance.

The purpose of this study is to present a framework of the MyData business ecosystem that shows a different pattern from the previous one by the MyData concept and to define the characteristics of actors participating in the ecosystem. Because MyData is an individual exercising sovereignty over his or her data, there is a characteristic that the individual participates as a key actor in the business. In other words, MyData Operators participate in the MyData business ecosystem to help individuals who own MyData, MyData creating business and MyData using business, among them, manage their own data. Therefore, this study conducts a case study of domestic and foreign MyData businesses to revitalize the domestic MyData industry. In particular, the business model of 45 cases of overseas MyData operators was analyzed and classified into 7 types of 4 groups. And through this, the importance of the role of MyData Operator in the MyData industry ecosystem is confirmed and a developmental ecosystem model is proposed.

This study is a study on the filter bubble reinforcement phenomenon of SNS recommendation algorithm such as YouTube, which is a characteristic of the Russian-Ukraine war (2022), and the victory or defeat factors of the hybrid war. This war is identified as a hybrid war, and the use of New Media based on the SNS recommendation algorithm is emerging as a factor that determines the outcome of the war beyond political leverage. For this reason, the filter bubble phenomenon goes beyond the dictionary meaning of confirmation bias that limits information exposed to viewers. A YouTube video of Ukrainian President Zelensky encouraging protests in Kyiv garnered 7.02 million views, but Putin's speech only 800,000, which is a evidence that his speech was not exposed to the recommendation algorithm. The war of these SNS recommendation algorithms tends to develop into an algorithm war between the US (YouTube, Twitter, Facebook) and China (TikTok) big tech companies. Influenced by US companies, Ukraine is now able to receive international support, and in Russia, under the influence of Chinese companies, Putin's approval rating is over 80%, resulting in conflicting results. Since this algorithmic empowerment is based on the confirmation bias of public opinion by 'filter bubble', the justification that a new guideline setting for this distortion phenomenon should be presented shortly is drawing attention through this Russia-Ukraine war.

Modeling of artificial targets in Synthetic Aperture radar (SAR) mainly simulates radar signals reflected from the faces and edges of the 3D Computer Aided Design (CAD) model with a ray-tracing method, and modeling of the clutter on the Earth's surface uses a method of distinguishing types with similar distribution characteristics through statistical analysis of the SAR image itself. In this paper, man-made targets on the surface and background clutter on the terrain are integrated and made into a three-dimensional (3D) point cloud scatterer model, and SAR image were created through computational signal processing. The results of the SAR Stripmap image generation of the actual automobile based SAR radar system and the results analyzed using EM modeling or statistical distribution models are compared with this 3D point cloud scatterer model. The modeling target is selected as an bridge because it has the characteristic of having both water surface and ground terrain around the bridge and is also a target of great interest in both military and civilian use.

The design of children's hospitals is highly dependent on color schemes. As a space shared together by both adults and children, the design of children's hospitals require color coordination that takes account of the users' characteristics. However, because the majority of prior research on color perception has focused overly on the emotional aspects, there is a necessity for more rational and scientific analyses to identify the characteristics of the visual perception of colors. Adopting this perspective in analyzing the characteristics of the visual perception of colors, this study aims to move beyond the abstract to focus on more objective methods, such as eye-tracking experiments, to examine the characteristics of hospital visitors' visual attention with respect to colors. Visual perception tracking experiment was conducted on the 2 chosen experimental images with a target group made up of adults and children, the following results were found. Firstly, spaces created with the preference colors of the different groups were found to develop a characteristic of developing higher attention. Secondly, observing the common tendencies for attention for adults and children, the highest region for visual concentration was formed towards the middle, as attention progresses to lower stages visually focused area changes in the order of upper-middle, left and right, and lower regions and edge regions show characteristics of not triggering attention Thirdly, it is understood that children's level of attention drops a lot faster than adults when identifying space therefore it is suspected that children need more elaborate color coordination than adults.

The purpose of this study is to study the impact of knowledge sharing behavior, self-efficacy, team collaboration, and job autonomy on organizational innovation among the smart work characteristic factors for members of small and medium-sized venture companies, and to study the differences according to generation/digital literacy level. It is to provide implications so that it can be reflected in the organizational innovation of venture companies. As a result of the analysis, it was found that knowledge sharing behavior and team collaboration had an effect on organizational innovation, while self-efficacy and job autonomy did not affect organizational innovation. In addition, as a moderating effect, it was confirmed that there were differences in self-efficacy and team collaboration according to the level of digital literacy, and differences in knowledge sharing behavior, self-efficacy, and team collaboration by generation. Therefore, in this study, we identified important influencing factors for organizational innovation according to changes in the smart work environment of small and medium-sized venture companies, and suggested ways to secure corporate competitiveness. It suggests that organizational innovation can be strengthened only by confirming the relationship between organizational innovation and finding ways to develop and utilize differentiated capabilities.
