"Obi Reborn" Art

( Kensei Takeda ) 복식문화학회 2003 워크샵 Vol.2003 No.-

In addition to the known and intended use of Japanese "obi" as a sash to the traditional kimono outfit, it has been used for years as a decorative accessory to interior design. They are often seen as tapestries hung on walls, runners on tables and dressers and sometimes are used in the recreation and design of clothing. Several years ago, as a result of his lifelong interest in art, both western and Asian, Mr. Takeda decided to give a rebirth to antique obi which otherwise might not have been used again. Oftentimes, obi cannot be used as a result of wear or soiling to the material. However, due to the extreme length of the article, there are nearly always sections of obi which can be salvaged and given new life. This has been the challenge of Mr. Takeda, and he has created vibrant framed art using obi, obi ties ("obijime") and kimono material as the main media for this unique type of art. In this presentation, several examples of orginal antique obi were presented to the participants and the finished art works were then shown to demonstrate how the obi and accessories were assembled, painted, matted and framed to bring about the finished pieces. Depending on the artists location, one of the most difficult tasks in preparing to create these works is the actual finding of the antique obi. They can usually be found in Japanese antique shops or used kimono shops. Furthermore, the artist must be able to look at various obi, kimono and accessories and visualize the artistic layout possible with the materials at hand. Obviously, all antique obi and related material do not lend themselves to being paired with other material, and in many cases the condition of the material must be carefully inspected. Silk becomes very delicate with age, and antique obi can easily tear or even disintegrate when washed and stretched. In some cases, only trial and error will determine if a particular piece of material can be used in this manner. Although it was not feasible to demonstrate the washing, drying pressing, stretching and mounting of the obi at this particular demonstration, the procedure was described. An orginal obi was presented to the audience in it``s state before the above-mentioned steps. Then, a mounted portion of the same obi was offered as a working sample. Mr. Takeda uses acrylic and water colors, usually straight from the tube and undiluted, as his paint media. A short demonstration of the painting technique was demonstrated. The traditional wearing of kimono is a harmony of pattern, color, texture and layering of material. Mr. Takeda keeps this same concept in his art. Very old Japanese art tends to be flat, but he strives to bring about dimension to the materials in his finished art work. At the same time, Mr. Takeda always respects the work of the original artist while creating his own image. Depending on the theme of the work, he occasionally uses other materials such as beads, and in some instances, antique pieces of jewelry. In this way, each wark takes on a truly three-dimensional form. The choice of his frames is influenced by the environment in which the art is to be displayed. Although the initial materials are of Japanese origin, the frames reflect the interior design of the environment in which the art is to be shown. Also, both the frames and the mats are partially chosen based on the theme or title of the finished work. Mr. Takeda``s final works of art are a result of not only painting, but also manipulation and co-ordination of various materials related to kimono. It was a result of his long-time appreciation of traditional kimono and obi that he started to use these materials in his art. In this way, he has created objects of art which allow viewers to enjoy these traditional materials in everyday life.

Monitoring of a CFRP-Stiffened Panel Manufactured by VaRTM Using Fiber-Optic Sensors

Takeda, Shin-Ichi,Mizutani, Tadahito,Nishi, Takafumi,Uota, Naoki,Hirano, Yoshiyasu,Iwahori, Yutaka,Nagao, Yosuke,Takeda, Nobuo The Korean Society for Composite Materials 2008 Advanced composite materials Vol.17 No.2

FBG (Fiber Bragg Grating) sensors and optical fibers were embedded into CFRP dry preforms before resin impregnation in VaRTM (Vacuum-assisted Resin Transfer Molding). The embedding location was the interface between the skin and the stringer in a CFRP-stiffened panel. The reflection spectra of the FBG sensors monitored the strain and temperature changes during all the molding processes. The internal residual strains of the CFRP panel could be evaluated during both the curing time and the post-curing time. The temperature changes indicated the differences between the dry preform and the outside of the vacuum bagging. After the molding, four-point bending was applied to the panel for the verification of its structural integrity and the sensor capabilities. The optical fibers were then used for the newly-developed PPP-BOTDA (Pulse-PrePump Brillouin Optical Time Domain Analysis) system. The long-range distributed strain and temperature can be measured by this system, whose spatial resolution is 100 mm. The strain changes from the FBGs and the PPP-BOTDA agreed well with those from the conventional strain gages and FE analysis in the CFRP panel. Therefore, the fiber-optic sensors and its system were very effective for the evaluation of the VaRTM composite structures.

Management of disseminated intravascular coagulation associated with placental abruption and measures to improve outcomes

Jun Takeda,Satoru Takeda 대한산부인과학회 2019 Obstetrics & Gynecology Science Vol.62 No.5

Placental abruption is a condition that should be carefully considered in perinatal management because it is associatedwith serious events in both the mother and neonate, such as intrauterine fetal death, cerebral palsy, obstetric criticalbleeding, and uncontrollable bleeding. The concomitant presence of disseminated intravascular coagulation (DIC)more easily causes critical bleeding that may necessitate hysterectomy or multi-organ failure resulting in maternaldeath. Therefore, early management should be provided to prevent progression to serious conditions by performingboth hemostatic procedures and DIC treatment. To take measures to improve the outcomes in both the mother andneonate, health guidance for pregnant women, early diagnosis, early treatment, development of the emergency caresystem, and provision of a system for transport to higher-level medical institutions should be implemented.

Do Hertzsprung‐gap stars show any chemical anomaly?

Takeda, Yoichi,Jeong, Gwanghui,Han, Inwoo WILEY‐VCH Verlag GmbH Co. KGaA 2019 Astronomische Nachrichten Vol.340 No.5

<P><B>Abstract</B></P><P>With the aim of investigating how the surface abundances of intermediate‐mass stars off the main sequence (evolving toward the red‐giant stage) are affected by the evolution‐induced envelope mixing, we spectroscopically determined the abundances of Li, C, N, O, and Na for selected 62 late A through G subgiants, giants, and supergiants, which are often called “Hertzsprung‐gap stars,” by applying the synthetic spectrum‐fitting technique to Li <SMALL>i</SMALL> 6708, C <SMALL>i</SMALL> 5380, N <SMALL>i</SMALL> 7460, O <SMALL>i</SMALL> 6156–8, and Na <SMALL>i</SMALL> 6161 lines. A substantially large star‐to‐star dispersion (≳2 dex) was confirmed for the Li abundances, indicating that this vulnerable element can either suffer significant depletion before the red‐giant stage or almost retain the primordial composition. Regarding C, N, O, and Na possibly altered by dredge‐up of nuclear‐processed products, their abundances turned out to show considerable scatter. This suggests that these abundance results are likely to suffer appreciable uncertainties, the reason for which is not clear but might be due to some kind of inadequate modeling for the atmospheric structure. Yet, paying attention to the fact that the relative abundance ratios between C, N, and O should be more reliable (because systematic errors may be canceled as lines of similar properties are used for these species), we could confirm a positive correlation between [O/C] (ranging from ∼0 to ∼+0.5 dex) and [N/C] (showing a larger spread from ∼0 to ∼+1 dex), which is reasonably consistent with the theoretical prediction. This observational detection of C deficiency as well as N enrichment in our program stars manifestly indicates that the dredge‐up of H‐burning product can take place before entering the red‐giant stage, with its extent differing from star to star.</P>

Controlled Microstructure for Optimum Fatigue Performance

Takeda Yoshinobu,Bergmark Anders,Alzati Luigi,Bengtsson Sven 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1

Optimized choice of material for two principally different types of PM components is presented. The first is characterized by high stresses in areas with high stress concentrations (for example synchronizer hubs with very sharp notches, typically <0.25mm in the pre-synchronizer slot and the inner splines). The second type has slightly larger notch radii (small spur gears and sprockets with typically notch radii between 1- 3mm). Diffusion alloyed materials are well suited for sharp notch components. Pre-alloyed materials are also well suited for applications with sharp notches if compressive residual stresses in the notch roots are created by appropriate process control. A free choice of material is available for components with the larger notch radii.

SAFETY STUDIES ON HYDROGEN PRODUCTION SYSTEM WITH A HIGH TEMPERATURE GAS-COOLED REACTOR

TAKEDA TETSUAKI Korean Nuclear Society 2005 Nuclear Engineering and Technology Vol.37 No.6

A primary-pipe rupture accident is one of the design-basis accidents of a High-Temperature Gas-cooled Reactor (HTGR). When the primary-pipe rupture accident occurs, air is expected to enter the reactor core from the breach and oxidize in-core graphite structures. This paper describes an experiment and analysis of the air ingress phenomena and the method fur the prevention of air ingress into the reactor during the primary-pipe rupture accident. The numerical results are in good agreement with the experimental ones regarding the density of the gas mixture, the concentration of each gas species produced by the graphite oxidation reaction and the onset time of the natural circulation of air. A hydrogen production system connected to the High-Temperature Engineering Test Reactor (HTTR) Is being designed to be able to produce hydrogen by themo-chemical iodine-Sulfur process, using a nuclear heat of 10 MW supplied by the HTTR. The HTTR hydrogen production system is first connected to a nuclear reactor in the world; hence a permeation test of hydrogen isotopes through heat exchanger is carried out to obtain detailed data for safety review and development of analytical codes. This paper also describes an overview of the hydrogen permeation test and permeability of hydrogen and deuterium of Hastelloy XR.

Takeda. Mitsuhiro,Otsuka. Koji,Lee. Sang-Hun 한국방재학회 2008 한국방재학회 학술발표대회논문집 Vol.2008 No.1

본 연구의 목적은, X선조영촬영을 이용한 콘크리트강도의 평가 및 콘크리트열화의 수치화를 수행하는 것이다. 콘크리트강도를 추정하기 위하여, 물-시멘트비가 서로 다른 콘크리트를 제작하여, X선투과선량과 콘크리트강도의 관계를 구하였다. 이 실험에는 콘크리트 외에 몰탈, Non-AE 콘크리트를 이용한 실험도 수행하였다. 또한, 동결융해작용을 가해 상대동탄성계수를 변화시킨 공시체에 대하여, 열화의 수치화를 수행하였다. 실험의 결과, X선조영촬영법을 사용하면, 투과선변화량이 구해지므로, 콘크리트강도의 추정과 열화의 수치화가 가능하다는 것을 알았다. The purposes of this study are to estimate thestrength of concrete and quantify the deterioration of concrete by a unique X-ray technique with a contrast medium. In order to estimate the strength of concrete, specimens with different water-cement ratios were fabricated using non-air-entrained concrete, air-entrained concrete and mortar to determine the relationship between their compressive strength and the transit dose obtained by the X-ray technique. Also, an experiment to quantify deterioration was carried out on specimens that were subjected to freezing and thawing action to different levels of dynamic elastic modulus. As a result of this experiment, estimation of the strength and relative dynamic elastic modulus of deteriorated mortar, concrete and air-entrained concrete was found feasible by measuring the transit dose by the X-ray technique.
