Live cinema theatre is the latest installment of multimedia show where the filming of the performance of dramatic texts becomes the live stage event. Here, the actors perform before the camera and all the audio-visual effects are produced and constructed live. Mediated through the camera and projection screen, the stage image becomes a real-time production situation where all the scenes are put together right in front of a live audience. The very concept of live cinema as dramatic theatre has been developed by English stage director Katie Mitchell who attempts to present the stage as a cohesive representation system; this is more than a provisional experimentation where the ever-changing notion of in-betweenness is constantly tested. It is rather a predetermined operational system where the relationship between cinema and theatre is governed by the logic of synchrony, therefore maintain their own individual institutional reality. Here, the presence of camera has an effect not only on the organization of stage but also an affect on how human body exists within the situation.

Agricultural gear reducers are used in a variety of agricultural machinery designs such as in agricultural tractors and transport cars, and even greenhouses. For greenhouses, a gear reducer is used to control windows on the side and the roof. Gear reducers for agricultural applications are designed using the empirical method because of the lack of a standard for experimentation. Simulation is necessary for the optimal design of an agricultural gear reducer. There are many advantages to this optimization such as low-cost maintenance, reduced size, and weight. In this study, bending and contact safety factor simulation for the gear reducer of a greenhouse was conducted by decreasing the face widths of helical gear shaft 2 and shaft 3 from 30.8 and 30 mm, respectively, at an interval of 4 mm. The bending and contact safety factors were calculated using AGMA standard. Simulation results showed that bending and contact safety factors decreased rapidly when the face width of the helical gear on shaft 2 was 30 mm and the face width of helical gear on shaft 3 decreased from 30.8 mm to 26.8 mm, suggesting that it would be safe to reduce the face width of the helical gear on shaft 3 to 26.8 mm. The reduction of the face width also reduced the weight of the agricultural gear. This study suggests that the agricultural gear reducer safety factor decreases as the face width decreases.

The modern day architectural giant, Maki Fumihiko, has lived through both the early and the more recent modernism, Contemporary. In the 1950's he was faithful to the spirit that was founded on the early modernity, Metabolism. In his later years in the 2000's, his style can be distinguished into Neo-Modernism which was based on local influence. The educational system at Washington University and the modern city of Saint Louis carries the continuation of Fumihiko Maki's early and later architectural career. Steinberg Hall and Kemper Art Museum have been built adjacent to each other in an extended period of time. These two projects encompass the changes in the era that has gone through modernism, transformation of an architect's career, and the maturation of the university. Steinberg Hall carries the ideal and the spirit of young Fumihiko Maki, therefore, the basic platform of experimentation of the early Metabolist has been applied. Spatial theory that concentrates on the integration of relations is also evident in this project. In contrast, Kemper Art Museum expresses the work of a 78 year-old veteran from the perspective of Neo-Modernism. This piece focuses on the internal space through the coexistence of a variety of space, and with that it notably interprets the integration of the pieces to the whole as a set theory. The partial change that we see is the evidence of the change in the early and the later modernism, while maintaining the innocence and the spirit of it. This is to highlight the fact that, ultimately, the goal of architecture is to secure the human race's honesty and their freedom expressed through space.

Recently, there is a demand for efficient program development of an IoT application support frameworks considering heterogeneous hardware characteristics. In addition, the scope of hardware support is expanding with the development of neuromorphic architecture that mimics the human brain to learn on their own and enables autonomous computing. However, most existing IoT IDE(Integrated Development Environment), it is difficult to support AI(Artificial Intelligence) or to support services combined with various hardware such as neuromorphic architectures. In this paper, we design an AI component abstract model that supports the second-generation ANN(Artificial Neural Network) and the third-generation SNN(Spiking Neural Network), and implemented an autonomous IoT IDE based on the proposed model. IoT developers can automatically create AI components through the proposed technique without knowledge of AI and SNN. The proposed technique is flexible in code conversion according to runtime, so development productivity is high. Through experimentation of the proposed method, it was confirmed that the conversion delay time due to the VCL(Virtual Component Layer) may occur, but the difference is not significant.

The purpose of this study is to develop education programme on climate change for elementary students which is based on student activity. The programme is intended to raise children's awareness and to build positive attitudes towards climate change. Ten programmes are developed. The main themes of the contents are 'a meteorological observation', 'a change of season', 'the monitoring climates of the past', 'the climate and life', 'the climate and human lives', 'the causes of climate change', 'the influence of the climate change' and 'the action on climate change' which are selected from the survey of previous domestic education programmes. Each programme consists of 5 steps: Introduction, Concrete experience, Reflective observation, Abstract conceptualisation and Active experimentation. We expect that this programme would enhance children's awareness and attitudes on climate change and induce positive and active response to climate change.

Along with the advances in medical technology and the economic development, more terminally ill patients are receiving hospice and palliative care services. Moreover, hospice and palliative care clinicians have been showing considerable interest in studies that aim to improve the quality of said care for patients and their families. Meanwhile, after the government has strengthened its policy to protect research participants, the institutional review boards (IRBs) are more closely examining various ethical issues related to patients' vulnerability when reviewing protocols for hospice and palliative care research. However, terminally ill patients should be provided with guaranteed qualities of hospice and palliative care to improve and maintain their quality of life. To that end, support should be provided for efforts to conduct ethical and safe studies with hospice and palliative care patients. Thus, this review paper proposes ethical guidelines for hospice and palliative care research. The guidelines could be appropriately used as a reference for researchers who should prepare for ethically safe and scientifically valued research protocols and the IRBs that will review the protocols.

In some image processing system or the users who want to see a specific region of image simply, if a part of the image has higher quality than other regions, it would be a nice service. Specifically in mobile environments, preferential service was needed, as the screen size is small. So, JPEG2000 supplies this function. But this doesn't support the process to extract specific regions or service and does the functions to add some techniques. It is called by ROI(Region-of-Interest). In this paper, we use images including human faces, which are processed most preferentially and compressed with high quality. Before an image is served to the users, it is compressed and saved. Here, the face parts are compressed with higher quality than the background which are relatively with lower quality. This technique can offer better service with preferential transferring of the faces, too. Besides, whole regions of the image are compressed with same quality and after searching the faces, they can be preferentially transferred. In this paper, we use a face extraction approach based on neural network and the preferential processing with EBCOT of JPEG2000. For experimentation, we use images having several human faces and evaluate objectively and subjectively, and proved that this approach is a nice one.

Recently the global epidemic problem of obesity has stimulated intense interest in the study of physiological mechanisms using animal models as a way to gain crucial data required for translation to human studies. Panax ginseng has been reported to have anti-obesity or antidiabetic effects in many animal studies; however, there have been few studies investigating human obesity. Herein, we will assess and examine the evidence supporting the anti-obesity effect of Panax ginseng in animal models with respect to anthropometric and metabolic outcomes. We will include controlled, comparative studies assessing the effect of Panax ginseng in preclinical studies of obesity. Panax ginseng will be administered during or following the induction of experimental obesity. The primary outcome measure will be anthropometric assessment and the secondary outcome measures will include adipose tissue weight, total amount of food consumed and metabolic parameters. We will search MEDLINE, Embase, PubMed, Web of Science, and Scopus without language, publication date, or other restrictions. Ethical approval will not be necessary as the data collected in this study will not be individual patient data, consequently there will be no concerns about violations of privacy. After finishing the whole procedure, the results will be disseminated by publication in a peer-reviewed journal or presented at a relevant conference. This protocol has been registered on the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADES) website (http://www.camarades.info).

Recently, a variety of AI-based platform services are available, and one of them is ChatGPT that processes a large quantity of data in the natural language and generates an answer after self-learning. ChatGPT can perform various tasks including software programming in the IT sector. Particularly, it may help generate a simple program and correct errors using C Language, which is a major programming language. Accordingly, it is expected that ChatGPT is capable of effectively using Verilog HDL, which is a hardware language created in C Language. Verilog HDL synthesis, however, is to generate imperative sentences in a logical circuit form and thus it needs to be verified whether the products are executed properly. In this paper, we aim to select small-scale logical circuits for ease of experimentation and to verify the results of circuits generated by ChatGPT and human-designed circuits. As to experimental environments, Xilinx ISE 14.7 was used for module modeling, and the xc3s1000 FPGA chip was used for module embodiment. Comparative analysis was performed on the use area and processing time of FPGA to compare the performance of ChatGPT products and Verilog HDL products.

A two-wheel balancing vehicle, which helps people moving freely and fast, and is applied from inverted pendulum system, has been widely researched and developed, and some products are came into a market in actuality. Until now, the two-wheel balancing vehicles developed have chosen the general PID control method. In this paper, we propose a new control method to improve a control capacity for a two-wheeled balancing vehicle for human transportation. The proposed method is the fuzzy PD+I control that is one of the improved PID control, and it contains a 2input-1output fuzzy system. This fuzzy system processes signals from proportional and derivative controller, and the fuzzy output signal generates the final output by summing up integral signal. The non-linearity of the fuzzy system makes an optimal output control signal by changing weight of the proportional signal and the derivative signal in process of time. We have simulated the fuzzy PD+I control system and experimented by implementing the two-wheel balancing mobile robot to verify the advantages of the proposed fuzzy PD+I control method in comparison with general PID control. As the results of simulation and experimentation, the proposed fuzzy PD+I control method has better control performance than general PID in this system and improves it.
