A study on the tradition of Judo : Focusing on “qualitative thoughts on traditional Japanese values”

J-GLOBAL ID : 200901048993785165This study aimed to re-evaluate the diverse values of Judo from the perspective of physical techniques. It also attempted to clarify the various values in the Budo in order to further advance Judo while embracing its local and global characteristics. 　The dilution of the culture of modern Judo is gaining attention as one of its problems, and the concepts of competition and victory are typical examples. However, the competitive nature of Judo is a valuable concept. Therefore, its traditional nature has to be maintained while including competitiveness. “Human development” is closely related to the tradition of Budo, and an attempt at “human development” is closely linked to the traditional idea of education in Japan. Thus, it clearly exhibits exposure to valuable concepts in conjunction with the learning of physical skills. In addition, it can be regarded as an activity that represents the culture of a “Path” that involves multifaceted growth at the same time. A discussion of aspects like that will also reveal some of the qualitative thoughts on traditional values unique to Japan.1520860078895597568application/pdfdepartmental bulletin pape

A study on the tradition of Judo : Focusing on “qualitative thoughts on traditional Japanese values”

J-GLOBAL ID : 200901048993785165This study aimed to re-evaluate the diverse values of Judo from the perspective of manner. It also attempts to consider the prospect of martial arts, which respects tradition but looks ahead to further development. Budo in modern society recognizes great value in competition. However, its maturity is different compared to that as a cultural entity. Therefore, the individual is immature as a Budo athletes. The way Budo adapt to modern society should be a culture that can include such athletes, and we need someone to guide them. 　Judo shows the methods and processes of education for various purposes. However, the goal of integrating those “Michi” is cultural excellence. Thus, Judo and other martial arts are systems that aim to develop maturity in cultural beings. Moreover, a new martial arts culture will continue to be created by the mature existence there. Therefore, the development potential of culture by the mutual relationship between humans and culture and universal value thinking at the core of that interaction are the traditional qualities of Budo. We will disseminate the structure and elements globally. Furthermore, efforts to popularize better Budo will be the foundation that will support the future development of the Budo.1520015653966844416application/pdfdepartmental bulletin pape

Modified Armijo line-search in Riemannian optimization with reduced computational cost

In this paper, we propose a new line-search method that improves the ordinary Armijo line-search in Riemannian optimization. For optimization problems on Riemannian manifolds, many types of globally convergent algorithms have been proposed, and they are often equipped with the Armijo line-search in Riemannian optimization for global convergence. Such existing methods need the computation of a retraction regarding the search direction for each iteration. On the other hand, the proposed line-search decreases the computational cost by incorporating a new strategy that computes the retraction only if a promising candidate for the step length is found. We further present a Riemannian Newton method with the new line-search strategy and prove its global convergence

GREEMA: Proposal and Experimental Verification of Growing Robot by Eating Environmental MAterial for Landslide Disaster

In areas that are inaccessible to humans, such as the lunar surface and landslide sites, there is a need for multiple autonomous mobile robot systems that can replace human workers. In particular, at landslide sites such as river channel blockages, robots are required to remove water and sediment from the site as soon as possible. Conventionally, several construction machines have been deployed to the site for civil engineering work. However, because of the large size and weight of conventional construction equipment, it is difficult to move multiple units of construction equipment to the site, resulting in significant transportation costs and time. To solve such problems, this study proposes a novel growing robot by eating environmental material called GREEMA, which is lightweight and compact during transportation, but can function by eating on environmental materials once it arrives at the site. GREEMA actively takes in environmental materials such as water and sediment, uses them as its structure, and removes them by moving itself. In this paper, we developed and experimentally verified two types of GREEMAs. First, we developed a fin-type swimming robot that passively takes water into its body using a water-absorbing polymer and forms a body to express its swimming function. Second, we constructed an arm-type robot that eats soil to increase the rigidity of its body. We discuss the results of these two experiments from the viewpoint of Explicit-Implicit control and describe the design theory of GREEMA

Moving into kinesthetic intelligence

　This study aims to discuss the relationship between the self and the others as developed by key concepts such as rule or manner in terms of kinesthetic intelligence. It also argues on the matter of cultural generation created by man’s movement from the theory of human relations beyond the mere framework of self–others. Man’s movement acquired from external factors based on body awareness is called as bodily technique. M. Mauss deciphers much of man’s cultural or habitual behaviors. He perceives all kinesthetic movements as man’s bodywork and explains that man’s bodywork is acquired by a man himself and acts upon his way of living. It is a process of cultural succession created in relation to others and may be called as the cultural difference of intelligence learning through the body. This view of cultural difference might lead to an argument that confronts the current issue on the education of the body.　On discussing the issue of relationship to others, the concept of self-control is an important viewpoint. It is generally called as manner and the concept is vague compared with rule or morals. That is to say, the exertion of manner is insistently a value-concept supported by free will. However, for the body directed to others and bodily usage, because it is to come to the others, more culturally mature acts, namely a man’s bodywork of manner, are demanded. It is sometimes called saho (manner, etiquette, propriety) and regarded as a sort of a ritual aspect of acts required in a certain culture. The way of saho is to aim to limit the comprehensive and ambiguous field of manner, for example, saho seen in certain cultures such as budo or sport is an art of manner based on the free will of the performers. Yet, it would indicate man’s possibilities for acts as bodywork beyond the stereotypical relationship to others such as being self-assertive, respectful of others, or obedience to rules

Strongly Iridescent Hybrid Photonic Sensors Based on Self-Assembled Nanoparticles for Hazardous Solvent Detection

Facile detection and the identification of hazardous organic solvents are essential for ensuring global safety and avoiding harm to the environment caused by industrial wastes. Here, we present a simple method for the fabrication of silver-coated monodisperse polystyrene nanoparticle photonic structures that are embedded into a polydimethylsiloxane (PDMS) matrix. These hybrid materials exhibit a strong green iridescence with a reflectance peak at 550 nm that originates from the close-packed arrangement of the nanoparticles. This reflectance peak measured under Wulff-Bragg conditions displays a 20 to 50 nm red shift when the photonic sensors are exposed to five commonly employed and highly hazardous organic solvents. These red-shifts correlate well with PDMS swelling ratios using the various solvents, which suggests that the observable color variations result from an increase in the photonic crystal lattice parameter with a similar mechanism to the color modulation of the chameleon skin. Dynamic reflectance measurements enable the possibility of clearly identifying each of the tested solvents. Furthermore, as small amounts of hazardous solvents such as tetrahydrofuran can be detected even when mixed with water, the nanostructured solvent sensors we introduce here could have a major impact on global safety measures as innovative photonic technology for easily visualizing and identifying the presence of contaminants in water

Remarkable effect of hydrogen-bonding interaction on stereospecificity in the radical polymerization of N-vinylacetamide

Radical polymerization of N-vinylacetamide (NVA) in toluene at low temperatures was investigated. It was found that the addition of Lewis bases or alcohol compounds significantly influenced stereospecificity in NVA polymerization. For example, syndiotacticity increased from 25% to 34% by adding tri-n-butyl phosphate at –40°C. Mono-alcohol compounds increased heterotacticity and heterotactic poly(NVA) with mr triad content of 58% was obtained at –40°C in the presence of 1,1,1,3,3,3-hexafluoro-2-propanol. Furthermore, isotactic poly(NVA) with mm triad = 49% was obtained at –60°C in the presence of diethyl L-tartrate. The NMR analysis demonstrated that complex formation between NVA monomer and the added agents, through hydrogen-bonding interaction, played an important role to induce the stereospecificity

Heterotactic poly(N-isopropylacrylamide) prepared via radical polymerization in the presence of fluorinated alcohols

Radical polymerization of N-isopropylacrylamide in toluene at –40°C in the presence of fourfold amounts of fluorinated alcohols was investigated. The 13C NMR analysis of the obtained polymers suggested that the addition of fluorinated alcohols induced heterotactic-specificity in radical polymerization of NIPAAm, although syndiotactic poly(NIPAAm)s were obtained by adding alkyl alcohols as we have previously reported. To the best of our knowledge, this is the first synthesis of heterotactic poly(NIPAAm)

Microfluidic cell engineering on high-density microelectrode arrays for assessing structure-function relationships in living neuronal networks

Neuronal networks in dissociated culture combined with cell engineering technology offer a pivotal platform to constructively explore the relationship between structure and function in living neuronal networks. Here, we fabricated defined neuronal networks possessing a modular architecture on high-density microelectrode arrays (HD-MEAs), a state-of-the-art electrophysiological tool for recording neural activity with high spatial and temporal resolutions. We first established a surface coating protocol using a cell-permissive hydrogel to stably attach polydimethylsiloxane microfluidic film on the HD-MEA. We then recorded the spontaneous neural activity of the engineered neuronal network, which revealed an important portrait of the engineered neuronal network--modular architecture enhances functional complexity by reducing the excessive neural correlation between spatially segregated modules. The results of this study highlight the impact of HD-MEA recordings combined with cell engineering technologies as a novel tool in neuroscience to constructively assess the structure-function relationships in neuronal networks.Comment: 18 pages, 5 figure
