Kumano, Takehito,Yoshida, Satoshi,Saburi, Kazuhiro Council on Tall Building and Urban Habitat Korea 2017 International journal of high-rise buildings Vol.6 No.3

This paper summarizes the structural concept and design of the "Nakanoshima Festival Tower West" in Osaka, Japan, which is 200m high and has a super-high damping system. Its superstructure is mainly composed of a central core and outer tube frames. It has a bottom truss structure at the boundary between the low-rise and mid-rise sections of the building, where the column arrangement is changed. Besides, the high-rise section of the building has a neck truss structure. These truss structures smoothly transfer the axial forces of the columns and reduce the flexural deformations induced by horizontal loads. Oil dampers with extremely high damping capacity are installed in the rigid walls named the "Big Wall Frames" of the low-rise section. Moreover, many braces and damping devices are well arranged in the center core of each story. The damping effects of these devices ensure that all structural members are remain within the elastic range and that story drifts are within 1/150 in large earthquakes. This super-high damping structure in the low-rise section is named the "Damping Layer". The whole structural system is named the "Super Damping Structure". The whole structural systems enhance the building's safety, comfort and Business Continuity Planning (BCP) under large earthquakes.

Performance Evaluation of Stability Constrained ATC Estimator using Relevance Vector Machine

Kumano, Teruhisa,Wada, Akihiro 대한전기학회 2013 The Journal of International Council on Electrical Vol.3 No.4

RVM (Relevance Vector Machine) based ATC (Available Transfer Capability) estimator for its preliminary screening is proposed, which estimates the approximate value of ATC without long computing time. Starting from this obtained estimation, we can expect drastic saving of the time required to get accurate ATC. Comparisons are made between the proposed method and other existing methods. The performance of the proposed method is clarified by comparing the results with those of existing learning machines such as MLP (Multi-Layer Perceptron) and SVM (Support Vector Machine). In SVM the same kernel is used as in the proposed system. Not only the parameters in the proposed system but also all the parameters in MLP and SVM are carefully tuned to give the best results.

HIROYUKI KUMANO,Tatsunori Asaoka,Kento Sugaya,Yuta Mochizuki,Masashi Okada 대한설비공학회 2015 International Journal of Air-Conditioning and Refr Vol.23 No.4

Formation characteristics of propane hydrate using fiber layer were investigated experimentally. Water and propane gas contact in the fiber layer, and the propane gas hydrate can be formed continuously. In the experiment, pressure, temperature, the quantity of water and porosity of the fiber layer were varied as the experimental parameters, and the formation ratio and the formation rate were measured. As a result, it was found that the high formation ratio can be obtained by using the fiber layer. Therefore, it can be said that this method is useful to reduce energy consumption and to simplify the apparatus, since it does not need circulation system. Moreover, it was found that the formation rate increases with the subcooling and the quantity of water, and it is slightly affected by the porosity of the fiber layer

Measurement of Latent Heat of Tetra-n-Butyl Ammonium Bromide Hydrate and Specific Enthalpy of Its Slurry

HIROYUKI KUMANO,Tatsunori Asaoka,Tatsuya Hayashi,Peng Zhang 대한설비공학회 2015 International Journal of Air-Conditioning and Refr Vol.23 No.3

The specific heat of a tetra-n-butyl ammonium bromide (TBAB) aqueous solution, the latent heat of a TBAB hydrate, and the specific enthalpy of a TBAB hydrate slurry were measured to understand the thermal storage characteristics of TBAB hydrate slurry. A solution sample and the hydrate slurry were heated, the change in temperature was measured, and the specific heat of the TBAB aqueous solution and the specific enthalpy of the hydrate slurry were obtained from the change in temperature. Two types of TBAB hydrate form. Therefore, the hydrates were separated from the hydrate slurry formed from TBAB aqueous solution having several initial concentrations. The hydrate crystals were placed into solution, and the latent heats were obtained from the temperature change of the solution. The specific enthalpy of the hydrate slurry was estimated from the latent heats of the hydrate crystals and the specific heat of the solution under phase equilibrium conditions, and the measured and estimated values were compared.

Studies of water-in-oil (w/o) emulsion stabilized with amino acids or their salts

( Yoshimaru Kumano ),( Shin Nakamura ),( Sadaaki Tahara ),( Saburo Ohta ) 대한화장품학회 1977 대한화장품학회지 Vol.6 No.1

WATER-IN-OIL (W/O) EMULSIONS STABILIZED by using gels formed between surfactants and aqueous solutions of AMINO ACIDS were studied. The gel can only be obtained with a fluid surfactant which has lipophilic properties and a specific orderly lamellar structure and amino acids or their salts which are readily soluble in water. By dispersing these gels into the oil phase and then adding the water phase, extremely stable w/o emulsions with wide ranges of water content were obtained. This type of emulsification was termed the “gel-emulsification method” by the authors. When this new technology was applied to the preparation of cosmetics, products with outstanding characteristics were obtained. The function of the amino acids in the emulsification were investigated by using physico-chemical methods such as X-ray analysis, nuclear magnetic resonance (NMR), heat of solution, electron microscopy (EM), and measurement of the water content solubilized in the surfactant phase. It may be concluded that the amino acids are effective in forming a tight surface atmosphere around the water particles and in preventing coalescence of water particles by strong hydration effect of the amino acids, thus stabilizing the w/o emulsion.

マインドフルネス瞑想を通じた心理治療の脳科学的理解

熊野宏昭(Hiroaki Kumano) 동국대학교 불교문화연구원 2015 佛敎學報 Vol.0 No.71

본 논문의 테마는 ‘마인드플니스명상을 통한 심리치료의 뇌과학적 이해’이다. 이를 위해 이 분야의 최근의 연구를 중심으로 해서 포괄적인 전망을 하고자 한다. 우선, 마인드플니스 명상을 통한 심리치료에 대해서 간단히 고찰하고, 이에 근거하여 MBSR의 마인드플니스의 정의와 마인드플니스명상의 구성요소에 대해서 말하고자 한다. 특히, ① 주의의 관점에서의 분류 ② 실천의 시기에 따른 차이 ③ 주의제어의 차이에 따른 뇌의 사용법의 차이 ④ 3가지의 신경 네트워크와 자기지각을 중심으로 고찰한다. 이들 4가지 관점에서 뇌의 작용의 특성을 구명하는 것을 주된 목적으로 한다. 그 결과 얻은 결론의 주된 내용은 다음과 같다. · 마인드플니스 명상은 주의제어의 향상, 정서제어의 향상, 자기지각의 변용으로 구성된다. · 마인드플니스 명상의 주의제어에는 FA, OM의 요소가 포함되고, FA에서는 큰 기대효과와 그것에 상당하는 뇌기능의 변화가 초래되지만, OM에서는 장기효과의 측면이 중요하다. · 마인드플니스의 자기지각이 갖는 효과는 3가지의 신경네트워크와의 관련에서 설명할 수 있고, FA에서 SN의 발현, OM에서 SN의 우위성의 획득이 순간순간의 자신의 발현과 유지에 관계하고 있다. · 명상자가 마인드플니스 명상을 하면, DMN의 활동이 억제되는 것으로, 편도체의 활동을 억제하지 않고 정서제어가 가능해진다. · 행복감은 반복적 사고의 감소와 대응하지만, 그 신경기반으로서는 DMN의 중핵인 후부대상회와 SN에 포함되는 배측전대상회와의 기능성결합이 고조되는 것이 관여하고 있을 가능성이 높다. The focus of this study is “is e of this’s understanding of psychotherapy through mindfulness meditation.” To explore this, a general outline will be drawn with a focus on recent research carried out in this field. The first part of this manuscript is a simple evaluation of psychotherapy through mindfulness meditation and, based on this, an explanation of the definition of the “mindfulness” of Mindfulness-Based Stress Reduction (MBSR) and the components of mindfulness meditation. This evaluation was carried out with particular attention to: 1) the categorization of mindfulness from the perspective of attention; 2) differences depending on the timing of training; 3) differences in brain activity according to differences in attention control; 4) and three different nerve networks and self-perception. The main purpose was to clarify the characteristics of brain functions from these four perspectives. The results drawn from this were as follows: · Mindfulness meditation consists of enhancement of attention control, enhancement of emotional control, and transformation of self-perception. · Attention control in mindfulness meditation includes focused attention (FA) and open monitoring (OM). FA is expected to have remarkable effects and cause corresponding changes in brain function, while OM is expected to have a more significant long-term effect. · The effects of self-perception on mindfulness can be explained in relation to the three types of nerve networks and the manifestation of the Salience Network (SN) from FA. The SN becoming predominant in OM is related to the moment-bymoment manifestation and maintenance of one’s self. · When a meditator practices mindfulness meditation, the activities of the Default Mode Network (DMN) are suppressed, thereby making emotional control possible without restricting the activities of the amygdala. · Although diminished repetitive thinking produces a sense of happiness, there is a high chance that, based on this nerve structure the functional association of the posterior cingulate gyrus the nucleus of the DMN and the dorsal ACC a part of the SN will be heightened.

Cell fate polarization in ascidian mesenchyme/muscle precursors by directed FGF signaling and role for an additional ectodermal FGF antagonizing signal in notochord/nerve cord precursors

Kim, G. J.,Kumano, G.,Nishida, H. The Company of Biologists 2007 Development (Cambridge) Vol.134 No.8

<P>Asymmetric cell division plays a fundamental role in generating various types of embryonic cell. In ascidian embryos, asymmetric cell divisions occur in the vegetal hemisphere in a manner similar to those found in Caenorhabditis elegans. Early divisions in embryos of both species involve inductive events on a single mother cell that result in production of daughters with different cell fates. Here we show in the ascidian Halocynthia roretzi that polarity of muscle/mesenchyme mother precursors is determined solely by the direction from which the FGF9/16/20 signal is presented, a role similar to that of Wnt signaling in the EMS and T cell divisions in C. elegans. However, polarity of nerve cord/notochord mother precursors is determined by possible antagonistic action between the FGF signal and a signal from anterior ectoderm, providing a new mechanism underlying asymmetric cell division. The ectoderm signal suppresses MAPK activation and expression of Hr-FoxA, which encodes an intrinsic competence factor for notochord induction, in the nerve cord lineage.</P>
