  • In this paper we made the serious game learning multiplication table to be evolved. The serious game is to induce the interest of the learner. This program has an interaction form which reflects the intention of the user and using this program a learner to learn the multiplication table as teacher's location are training a program that are seen as the abata and came to be that learner is smart. A study ability to be evolved used an back propagation neural networks. But we improved a study speed using divided weight table concept. The engine is studied perfectly in 60~80 times training. The learning rate increase to various non-monotonic functional form not to do a mechanical rise. And the learning rate is similar with the study ability of the human.

  • Background: Although various conventional approaches have been employed to reduce spasticity in neurological rehabilitation, only a few studies have shown scientific evidence for its effectiveness. Thus, we introduced a different concept (Ueda method) of rehabilitation therapy that can complement the limitations of conventional therapy. Objects: This study aimed to investigate the immediate effects of the application of the Ueda method on patients with spasticity after stroke via an electrophysiological study. Methods: We conducted a randomized double-blind pilot study in two rehabilitation hospitals involving 30 stroke patients who were randomly allocated to the Ueda (n = 15) and convention (n = 15) groups. Electromyographic data of six examined muscles in both upper extremities of all patients were recorded. The A-ApA index and activation ratios of upper extremity muscles were evaluated and compared between the groups to confirm post-intervention changes in upper-extremity flexor spasticity and flexion synergies. Repeated-measures analysis of variance was conducted to confirm the therapeutic effect (2 × 2) as a function of group (Ueda vs. convention) and time (pre-/post-intervention) on all outcome measures (p < 0.05). Results: In the Ueda group, the mean A-ApA index values differed significantly before and after the intervention (p = 0.041), indicating a weak evidence level; however, the effect size was medium (d = -0.503). The interaction effects of the A-ApA index between the Ueda and convention groups and between pre-intervention and post-intervention stages were significant (p = 0.012). The effect size was large (np2 = 0.220). In the Ueda group, the activation ratios of the anterior deltoid fiber significantly decreased after the intervention in all reaching tasks. Conclusion: The Ueda method reduces upper-extremity flexor spasticity and changes its synergy in stroke patients and should be considered a rehabilitation therapy for spastic stroke patients.

  • There are many definitions around brand. It complexify academic literature. Thus, this study collected meaningful definitions among many statements about brand and analyzed and classified them by available perspectives. This is especially necessary contents in domestic brand study, which is short of concept research about brand. Various literatures are refereed to brand definition introduction. But to etymological definition, several European linguistic theses are deeply reviewed and to institutional definition, wide range of information such as history, law and society is refereed. Total brand definitions are classified in . It is divided into 2 parts which are non-commercial context (etymological and institutional definition) and commercial context (producer, customer and the relation or interaction between producer and customer). In etymological definition, the word origin is clear word 'brandr' which means 'burning wood' and cattle-brand made this 'brand'. In legal definition, legal and institutional meaning of 'trademark' is examined. Etymological definition and institutional definition are fundamental and lexical definition which show brand history. These are foundation stones in brand studies.

  • An urban inundation model coupling an one-dimensional stormwater model, SWMM(Storm Water Management Model), and a two-dimensional inundation model was developed to simulate inundation caused by the surcharge of storm sewers in urban areas. The limitation of this model which can not simulate the interaction between drainage systems and surcharged flow was resolved by developing Dual-Drainage inundation analysis model which was based upon hydraulic flow routing procedures for surface flow and pipe flow. The Dual-Drainage inundation analysis model can simulate the effect of complex storm drainage system. The developed model was applied to Dorim, catchment. The computed inundated depth and area have good agreement with the observed data during the flood events. The developed model can help the decision support system of flood control authority for redesigning and constructing flood prevention structures and making the potential inundation zone, and establishing flood-mitigation measures.

  • In case of application of electrophoresis method for leakage restoration of waste impoundment, main points of consideration were to evaluate the mobility of clay particles by electrophoretic force and capacity of leakage repair in leachate electrolyte system contained with various chemical species. However, the flocculation phenomena of clay particles induced by electrochemical interaction between various chemical species and clay particles would cause the big problems in electrophoresis method. Therefore, a series of laboratory tests such as one-dimensional electrophoresis and gravitational experiments were carried out in order to identify the specific chemical species affected flocculation of clay particles and the range of chemical concentration in leachate. In addition, the characteristics of clay particle behavior with chemical species and concentration range in leachate were analized using the concept of the settling velocity, zeta potential, and electrophoretic velocity.

  • Wetlands are one of the most vital natural habitats on the planet. India is incredibly blessed to have a number of multifunctional wetland ecosystems. Wetlands, in addition to their functional importance, can act as sources or sinks for greenhouse gases (GHGs) depending on their intrinsic factors. Carbon (CO2) and Methane (CH4) are the major greenhouse gases (GHG's) emitted in wetlands. It is demonstrated that, despite having 4.6 percent of its area covered by natural or man-made wetlands, being home to a large number of wetlands, and being the world's second largest cultivator of paddy, India's wetlands, including paddy fields that are intermittently flooded as typical wetlands, have been very poorly studied in terms of GHG emissions. The purpose of this paper is to examine the status of Indian wetlands and wetlands in terms of CH4 and CO2 emissions. The present study also reviews various literature to provide the equations, parameters that are required for estimating carbon and methane and some of the best strategies for conserving carbon in wetlands. The findings suggest that both non-manipulative and manipulative measures can be used to improve Carbon Sequestration (CS). Non-manipulative measures aim to improve CS by increasing the spatial extent of wetlands, whereas manipulative measures aim to change the characteristics of specific wetland components that influence CS. Uncertainty in carbon dynamics projections under changing environmental conditions is caused by a number of Knowledge gaps: i) There is a lack of knowledge on how organic matter mineralizes and partitions into carbon dioxide, methane, and dissolved organic carbon, ii) With the notable exception of methane dynamics, models that represent the dynamic interaction of processes and their controls have yet to be established. As a result, more research is needed to fully understand the importance of wetlands in terms of GHG emissions and carbon sequestration in India.

Between Man and Animal: Figuration of Animals in Children's Literature Focused on The Wind in the Willows (인간과 동물 사이 -아동문학의 동물 형상화 『버드나무 사이로 부는 바람』을 중심으로)

  • In "The Animal That Therefore I Am (More to Follow)," Derrida notices that he is being watched by his cat. He becomes ashamed of being naked in front of his cat. The sense of shame is a response to being reduced to the level of an animal. He is ashamed of being as naked as an animal. His next move is, therefore, to cover his nakedness from the gaze of his cat. By contrast, he realizes, the animal is not self-conscious of being naked and so does not shield its nudity. In a truer sense, then, the cat is not naked. Humans do not see animals for what they really are but what they project on them. Whereas the gap between man and animal is clearly identified by Derrida's philosophical discourse, the possibility of going beyond the gap can be suggested by fantasy stories in children's literature. Children's literature in Britain arose in the eighteenth century with the revival of traditional fairy tales and growth of literary fairy tales. Romanticism in the early nineteenth century contributed to opening up a new horizon for the concept of the child, in which the child is no longer defined as the object to be tamed and childhood imagination is glorified as a powerful means to reach the higher state, the spiritual origin prior to separation of Man from the 'thing-in-itself.' In The Wind in the Willows, animals talk and behave like humans. The anthropomorphic figuration of animals can be understood as a result of the one-sided projection of anthropocentric perspectives on animals rather than an interaction between humans and animals. Significant contradictions also emerge in this story, however, as traits particular to animals are vividly delineated even as the main didactic theme of good triumphing over evil reflects an anthropocentric projection on animals. An attempt to capture the true characteristics of animals and locate them in the text constitutes a remarkable achievement in The Wind in the Willows. This can be evaluated as an important step toward a more ecopocentric perspective on animals which appears in later children's fantasies like Charlotte's Web.

  • This study provides a systematic review of smart trade contracts, examining the research trends and theoretical background of utilizing smart contracts and blockchain technology for the digitalization and automation of trade contracts. Smart trade contracts are a concept that applies the automated contract system based on blockchain to trade-related transactions. The study analyzes the technical and legal challenges and proposes solutions. The technical aspect covers the development of smart contract platforms, scalability and performance improvements of blockchain networks, and security and privacy concerns. The legal aspect addresses the legal enforceability of smart contracts, automatic execution of contract conditions, and the responsibilities and obligations of contract parties. Smart trade contracts have been found to have applications in various industries such as international trade, supply chain management, finance, insurance, and energy, contributing to the ease of trade finance, efficiency of supply chains, and business model innovation. However, challenges remain in terms of legal regulations, interaction with existing legal frameworks, and technological aspects. Further research is needed, including empirical studies, business model innovation, resolution of legal issues, security and privacy considerations, standardization and collaboration, and user experience studies to address these challenges and explore additional aspects of smart trade contracts.

  • This study presents literature research on solitude and mental health in psychology as one of the problems in modern society. Solitude has been understood as a psychologically diverse concept. In psychology, solitude has been understood in a variety of ways: as a pathological phenomenon, a source of conflict in childhood, an expression of maladjustment, and a factor influencing current experiences. Solitude is an objective state of being alone without social interaction, while loneliness and privacy are subjective concepts, with loneliness indicating a need for the presence of others. On the contrary, the religious solitary is a solitary being before God. Isolation and sensory restriction, which humans voluntarily choose, is a cure for loneliness. Also, solitude is associated with positive well-being and healthy adaptability. Humans need to have inner freedom by turning loneliness into solitude. This suggests that loneliness can be overcome through solitude, and that positive thinking can overcome negativity, loneliness, and depression.

  • This study aims to develop and apply a metaverse-based instructional design model for the education in science and technology. It analyzed the concept and characteristics of metaverse, existing non-contact education models, and major teaching strategies systematically. Based on the prior researches, an instructional design model using metaverse is developed that presents metaverse-related teaching strategies and design principles for the before-, during-, and after-lesson phases. Then, this model was applied to a project-based learning program, conducted a perception survey on instructors and learners, and revised the metaverse instructional design model based on the results of the survey. In the Metaverse Instructional Design Model, before-lesson phase is a physical and psychological preparation stage for class participation, which includes familiarization with the Metaverse learning environment, formation of expectations for education, and self-directed pre-learning. During the lesson, to effectively deliver the lesson content, it is necessary to build confidence in the learning environment, promote learning participation, provide reference materials, perform team projects and provide feedback, digest learning content, and transfer learning content. The after-lesson phase provides strategies for ongoing interaction between learners and mentors. This study introduces a new instructional design model that utilizes metaverse and shows the potential of metaverse-based education in science and technology. It also has important implications in that it provides practical guidelines for the effective design and implementation of metaverse-based education.
