Constructed wetland has been widely used for the treatment of sewage, stormwater runoff, industrial wastewater, agricultural runoff, acid mine drainage and landfill leachate. For the removal of nitrogen and phosphorus, uptake by plants and adsorption to media material are the major processes, and, therefore, the selection of media with specific adsorption capacity is the critical factor for the optimal design of wetland along with the selection of appropriate plant species. In this study, two media materials (loess bead and mixed media) possessing different adsorption characteristics for ammonium and phosphate were selected, and their adsorption characteristics were evaluated. In addition, the performance of subsurface-flow wetland systems employing these media was evaluated in both batch and continuous flow systems. With LB medium, beter phosphorus removal was observed, while better ammonia removal was obtained with MM medium. In addition, enhanced removal efficiencies were observed in the wetland systems employing both media and aquatic plants, mainly due to the better environment for microbial growth. As a result, appropriate selection or combination of media with respect to the inflow water quality maybe important factors for the successful design and operation of wetland systems.

We present a method to recognize hand gestures using skeletal joint data obtained from Microsoft's Kinect sensor. We propose a combination feature of multi-angle histograms robust to orientation variations to represent the observation sequence of skeletons. The proposed feature efficiently represents the orientation variations of gestures that can be occurred according to person or environment by combining the multiple angle histograms with various angular-quantization levels. The gesture represented as combination of multi-angle histograms and random decision forest classifier improve the recognition performance. We conduct the experiments in hand gesture dataset obtained from a kinect sensor and show that our method outperforms the other methods by comparing the recognition performance.

Based on Merleau-Ponty and Lakoff's research on the inseparability of body and mind, this thesis seeks to explore the impact of experiences in multi-layered spaces based on media art on the understanding of human existence. The sensory experience provided by media art strengthens the viewer's physical presence and induces a new perception of reality by blurring the boundaries between reality and virtuality. Through this, it shows that it is possible to newly recognize and explore the deep relationship between human existence and the world. This paper analyzes how media art can be an important means of expanding existential experience through the connection between body and mind, and explains how the combination of art and technology contributes to ontological understanding.

The combination of Artificial Intelligence and the Internet of Things (AIoT) has gained significant popularity. Deep neural networks (DNNs) have demonstrated remarkable success in various applications. However, deploying complex AI models on embedded boards can pose challenges due to computational limitations and model complexity. This paper presents an AIoT-based system for smart parking lots using edge devices. Our approach involves developing a detection model and a decision tree for occupancy status classification. Specifically, we utilize YOLOv5 for car license plate (LP) detection by verifying the position of the license plate within the parking space.

The expansion of media is in close connection with the expansion of awareness. The invention of characters enabled mankind to cross over time and space. Machines led to the development of body functions and electricity led to the expansion of space and time. Computers are the extension of the human brain and the advent of the internet led to the expansion of relationships. Even at this moment, media is unremittingly progressing like a spread of a mutant virus, and has resulted in fusion and complex phenomena such as convergence and hybrid media. Transmedia is a compound word formed by the word "Trans" which means traverse, transcend, penetrate or change, and the word "Media" and has the meaning "media which transcends media" which embraces all of modern day media. However, unlike other fusion or complex media, it is different in that it is not a combination of technologies but a combination of technology and emotion. Thus, transmedia should be recognized as a form of media that carries a significant meaning from the user experience aspect as it must simultaneously satisfy both "emotional awareness", which appeals to the human emotion, and "conscious awareness" of mankind, which arises out of the digital technology considered to be important in the smart-era society. This study first examines the concept of transmedia, and then examines the role of user experience design which triggers conscious thinking and strategies for emotional marketing. This study aims to be recognized as a matter for consideration with respect to the development stage for the establishment of a steady communication relationship between developers and designers, as well as communication with users.

This study aims to understand the concept of pixel, the most important factor in constituting a digital image, draw the formative characteristics of pixelation image expressed through non-digital media, and develop fashion design reflecting the characteristics. As a research method, the literature review was conducted in the present study by involving domestic and foreign publications, related academic journals, and theses and dissertations on the pixel and pixelation image based on a qualitative research process. In addition, through an analysis of the cases that borrowed pixelation images in non-digital media like contemporary art and design, etc., an attempt was made to draw the formative characteristics of the pixelation image. Apparently, six fashion design looks are presented in the present study. The formative characteristics of the pixelation image include: first, the repeatability that repeats the minimum unit; second, the incompleteness of the shape appearing through the phenomenon of aliasing due to the characteristics of the pixel; and third, the combination that completes the shape through the combination of individual independent pixels. The results of the expression through reflecting them in fashion design are as follows: first, this study chose one small geometric formative element and presented repeatability by repetitively expressing that element in a textile pattern; second, for incompleteness, this study expressed an incomplete form, handling the edge part of the shape with the method of disentangling the strand; and third, the combination by completing a single look through overlapping of independent textiles and the combination of different independent individuals is expressed.

A visual method for the selective screen Eng of lignin degrading enzymes, produced by white rot fungi (WRF), was investigated by the addition of coloring additives to solid media. Of the additives used in the enzyme production media, guaiacol and RBBR could be used for the detection of lignin peroxidase (LiP), manganese peroxidase (MnP) and lactase. Syringaldazine and Acid Red 264 were able for the detection of both the MnP and lactase, and the LiP and laccase, respectively, and a combination of these two additives was able to detect each of the ligninases produced by the WRF on solid media.

Reducing media noise is a key to realizing high areal recording density. However, perpendicularly oriented Co-Cr films, stong candidates for high density recording media, have received little attention in terms of recording noise. We studied the noise characteristics of Co-Cr based alloy films by varying the compositionally separated structure. Co-Cr films with fine compositionally separated microstructure were observed to have low noise, which recording density dependence were negative or week. Studies on control of the microstructure and magnetic properties in combination with noise analysis are important to realize high density recording media.

In this study, we studied methods of communication among audiences, artwork and artist and analyzed interactive media art using the nonverbal communication methods. We analyzed the 4 types of nonverbal communication based on sign and meaning[1] and reclassified suitably for analysis of interactive media art. According to the analysis result, we draw typical characters by analyzing interactive media artwork which were corresponding to the each types. Also we analyzed overlap area and classify. Through these processes, we found communication methods in interactive media artwork connect audiences and artwork by organic combination of several nonverbal communication. In this paper, we suggest a new approach about the communication among audiences, artwork and artist through analyzing interactive media art using nonverbal communication.
