Through staggering advancements of technology and network as we know them as digital revolution, we have established a foundation of space in which we can express reality by eliminating the boundaries between expression, space, and movement. There are many ongoing approaches that aim to overcome the physically-fixed property of space where the mathematical-geometric notion of Voronoi Diagram is one of them. Although the repetitive increment based on self-organization during the process in which space is generated by the Voronoi Diagram forms a pattern and focuses on the formation, its pattern is not restricted to a single method of expression but evolves over self-control. The result of having analyzed spaces generated by the Voronoi Diagram in this study can be summarized as follows. First, the Voronoi computation method with self-organization property creates multiple levels, increments, and evolves through feedbacks among changes with the slightest order and in the absence of control. Secondly, after forming a pattern through such feedbacks comes the differentiation phase due to the presence of different properties. Thirdly, a space that has gone through the generation process retransforms through active interaction between changes and it obtains ambiguous boundaries and a repetitive pattern. This leads to an evolution of space through repetitive increments based on self-organization. Such flexible space creation is supported by various digital technologies where we believe a converging application of these studies, sciences, engineering concepts, and space design is and effective and new method in terms of space creation.

The Korean nuclear fuel cycle was modeled by the dynamic analysis method, which was applied to the once-through and alternative fuel cycles. First, the once-through fuel cycle was analyzed based on the Korean nuclear power plant construction plan up to 2015 and a postulated nuclear demand growth rate of zero after 2015. Second, alternative fuel cycles including the direct use of spent pressurized water reactor fuel in Canada deuterium uranium reactors (DUPIC), a sodium-cooled fast reactor and an accelerator driven system were assessed and the results were compared with those of the once-through fuel cycle. The once-through fuel cycle calculation showed that the nuclear power demand would be 25 GWe and the amount of the spent fuel will be ${\sim}65000$ tons by 2100. The alternative fuel cycle analyses showed that the spent fuel inventory could be reduced by more than 30% and 90% through the DUPIC and fast reactor fuel cycles, respectively, when compared with the once-through fuel cycle. The results of this study indicate that both spent fuel and uranium resources can be effectively managed if alternative reactor systems are timely implemented along with the existing reactors.

In the developing country like India, groundwater is the main sources for household, irrigation and industrial use. Its contamination poses hydro-geological and environmental concern. The hazardous waste sites such as landfills can lead to contamination of ground water. The contaminants existing at such sites can eventually find ingress down through the soil and into the groundwater in case of leakage. It is necessary to understand the process of migration of pollutants through sub-surface porous medium for avoiding health risks. On this backdrop, the present paper investigates the behavior of pollutants' migration through porous media. The laboratory experiments were carried out on a soil-column model that represents porous media. Two different types of soils (standard sand and red soil) were considered as the media. Further, two different solutes, i.e., non-reactive and reactive, were used. The experimental results are simulated through numerical modeling. The percentage variation in the experimental and numerical results is found to be in the range of 0.75- 11.23 % and 0.84 - 1.26% in case of standard sand and red soil, respectively. While a close agreement is observed in most of the breakthrough curves obtained experimentally and numerically, good agreement is seen in either result in one case.

Objectives The authors feel the Qi(氣) through the training, and diagnose and treat our patients through the feeling. In order to utilize the Qi-daignosis, we try to summarize the authors's training process by examining what and how to use the Qi-daignosis. Methods The authors have gathered empirical parts of the psychological part and the various methods of training, through what they need most and how to train them. And we want to describe them in order of importance. Result First of all, with psychological sense of securit you should practice trainingy. It should be able to maintain the unity of the body through relaxation on the basis of 'no thinking only watching'. You must concentrate your energy through concentration and strengthen your inner work. Then you can feel the flow of energy inside your body and you can feel the interaction between the outside and your body. Conclusion By doing this, you naturally begin to apply the Qi-daignosis to your patients. It is not only possible for some doctors with specific abilities. Anyone can feel the Qi(氣) through clinical training and use the Qi-daignosis.

Advanced Pressurized Water Reactors (APWRs) and Boiling Water Reactors (BWRs) employ a suppression pool as a heat sink to prevent containment overpressure. Steam can be discharged into the pool through multi-hole spargers or blowdown pipes in both normal and accident conditions. Direct Contact Condensation (DCC) creates sources of momentum and heat. The competition between these two sources determines the development of thermal stratification or mixing of the pool. Thermal stratification is of safety concern as it reduces the cooling capability compared to a completely mixed pool condition. In this work we develop a scaling approach to prediction of the thermal stratification in a water pool induced by steam injection through spargers. Experimental data obtained from large-scale pool tests conducted in the PPOOLEX and PANDA facilities, as well as simulation results obtained using validated codes are used to develop the scaling. Two injection orientations, namely radial injection through multi-hole Sparger Head (SH) and vertical injection through Load Reduction Ring (LRR), are considered. We show that the erosion rate of the cold layer can be estimated using the Richardson number. In this work, scaling laws are proposed to estimate both the (i) transient erosion velocity and (ii) the stable position of the thermocline. These scaling laws are then implemented into a 1D model to simulate the thermal behavior of the pool during steam injection through the sparger.

This paper is a study of "poetry therapy", a subject now in lively in literary discussion circles. Modern literary text attaches great importance to the readers' response. As such, there is growing interest in the effects of communication brought on by the interaction of participants in a discourse. Poetry, in essence, has therapeutic attributes of treating, through an aesthetic psychology, destruction resulting from the alienation from life and psychological pain of distortion. The rise of the concept of eco-poetry and the capacity for psychological cleansing and adjustment (which restores balance through communication and psychological circulation) is a reflection of new trend in research - approaching the alienation felt by modern people through restoration of sense of life. Although Kim Hyun-seung's life and the road his poetry took was not smooth, he nevertheless was firm in his sustained effort to unify socio-ethical conscience and conscience of faith through the process of spiritual inquiry. The most outstanding aspects of Kim Hyun-seung's aesthetic achievement lie in his contribution toward the therapeutic capacity of modern poetry. Kim Hyun-seung's poetryhas the following effects: 1)The therapeutic capacity of modern poetry, through catharsis at large, does not remain only at the level of cleansing and adjustment. 2)The therapeutic capacity of modern poetry has the function of emptying out the self through more fundamental spiritual awakening and insight. 3)Only then can one truly realize the transcendence of being a true self as well as the balanced inquiry of spirituality which can be described as "emptying out".

In the cloud environment, microservices are implemented through Kubernetes, and these services can be expanded or reduced through the autoscaling function under Kubernetes, depending on the service request or resource usage. However, the increase in the number of nodes or distributed microservices in Kubernetes and the unpredictable autoscaling function make it very difficult for system administrators to conduct operations. Artificial Intelligence for IT Operations (AIOps) supports resource management for cloud services through AI and has attracted attention as a solution to these problems. For example, after the AI model learns the metric or log data collected in the microservice units, failures can be inferred by predicting the resources in future data. However, it is difficult to construct data sets for generating learning models because many microservices used for autoscaling generate different metrics or logs in the same timestamp. In this study, we propose a cloud data refining module and structure that collects metric or log data in a microservice environment implemented by Kubernetes; and arranges it into computing resources corresponding to each service so that AI models can learn and analogize service-specific failures. We obtained Kubernetes-based AIOps learning data through this module, and after learning the built dataset through the AI model, we verified the prediction result through the differences between the obtained and actual data.

This study has investigated the effect of intentional contact through the intercom during MRI scans on the decrease of anxiety in patients. The results obtained through the test group and control group are as follows. 1. The homogeneity of the anxiety score before the scan between the two groups was not acknowledged, hence a significant result could not be deduced. 2. Intentional contact through the intercom displayed decreasing results rational discomfort (t=-2.214, p=.031). 3. Intentional contact through the intercom displayed decreasing results of (t=-3.722, p=.000), and fear (t=-2.74, p=.009). 4. Intentional contact through the intercom displayed decreasing results of heart rate (t=-4.180, p=.000). In conclusion, the attempt to perform MRI scans with intentional contact through the intercom did not display significant effect on the blood pressure of the subject after the scan, however, displayed a decrease in objective and rational discomfort, as well as the heart rate, another vital sign. Accordingly, it is judged that intentional contact through the intercom can be used as an effective substitutive treatment method in patient care and test, as it relieves psychological tension in the patient and allows the patient to feel stability.
