[Introduction] Larix kaempferi (Larch), rich biomass in Hokkaido, is available as an inexpensive medium for mushroom production. We have previously developed a variety of Hypsizygus marmoreus with high ability to utilize larch sawdust without watering, Hm 219 (Marbure 219) with high fruit-body yield and high score of sensory evaluation, was selected. In this study, we investigated the effects of supplements to larch sawdust-based medium on taste components of fruit-bodies of Hm 219. [Materials and methods] The strain of H. marmoreus used in this study was Hm 219, the stock culture of Hokkaido Research Organization Forest Products Research Institute. Each 850 ml plastic bottle containing 540 g of larch sawdust-based substrate, was used for cultivation. Moisture content of each medium was adjusted to 61% based on the fresh weight of the mixture of solid materials. The substrate substituted with 0-40% of supplements (wheat bran, soybean curd residue and soybean shell) for rice bran as a nutrient, were used for cultivation. Cultivation was conducted by the standard procedure reported earlier (Harada et al., 2004). The harvested fruit-bodies were freeze-dried to determine the chemical composition. Soluble sugars, free amino acids and 5’-nucleotides were extracted with hot water from freeze-dried powder. These soluble components were determined by using HPLC. [Results] As a result, fruit-body yields on the substrate substituted with 20% of soybean shell for rice bran as a nutrient, were about 20% higher than those on the substrate with rice bran only. According to the replacement rate of soybean curd residue increasing , morphological quality of fruit-body tended to decline. As major free amino acids in fruit-body, monosodium glutamate-like (MSG-like) components which gave the umami taste, including aspartic acid and glutamic acid, and sweet components including alanine, threonine and serine were detected. As flavor 5’-nucleotides, GMP and IMP were found. In fruit-body of H. marmoreus, with respect to major soluble sugars, mannitol and trehalose were mainly contained. Each taste component content indicated differences among the different supplements to larch sawdust-based medium. The equivalent umami concentration (EUC ) is the concentration of MSG equivalent to the umami intensity of that given by the mixture of MSG and the 5’-nucleotide (Lee, Yu-Ling et al., 2009). The EUC value in a cultivation condition was more 15% higher than that of control condition. [References] Harada, A. et al.

Prediction of Axial Thrust for Mixed-Flow Pumps with Vaned Diffuser by Using CFD

Harada, Ichiro,Kobayasi, Katsutoshi,Ono, Shigeyoshi 한국유체기계학회 2010 International journal of fluid machinery and syste Vol.3 No.2

It is important in pump design that the axial thrust of mixed-flow pump is predicted with high accuracy. In this paper, predictions of the axial thrust were carried out with CFD for mixed-flow pumps of three specific speeds. The region concerning the axial thrust prediction was picked out, and was divided into two parts. One of them was hydraulic part, which included the impeller and the vaned diffuser. The other was the rear part of impeller. These parts were calculated and evaluated individually. The CFD results were compared with experimental ones. They showed good agreements. It is shown that the axial thrust for a mixed-flow pump can be predicted by using CFD with practical accuracy.

GROSSBERG-KARSHON TWISTED CUBES AND BASEPOINT-FREE DIVISORS

HARADA, MEGUMI,YANG, JIHYEON JESSIE Korean Mathematical Society 2015 대한수학회지 Vol.52 No.4

Let G be a complex semisimple simply connected linear algebraic group. The main result of this note is to give several equivalent criteria for the untwistedness of the twisted cubes introduced by Grossberg and Karshon. In certain cases arising from representation theory, Grossberg and Karshon obtained a Demazure-type character formula for irreducible G-representations as a sum over lattice points (counted with sign according to a density function) of these twisted cubes. A twisted cube is untwisted when it is a "true" (i.e., closed, convex) polytope; in this case, Grossberg and Karshon's character formula becomes a purely positive formula with no multiplicities, i.e., each lattice point appears precisely once in the formula, with coefficient +1. One of our equivalent conditions for untwistedness is that a certain divisor on the special fiber of a toric degeneration of a Bott-Samelson variety, as constructed by Pasquier, is basepoint-free. We also show that the strict positivity of some of the defining constants for the twisted cube, together with convexity (of its support), is enough to guarantee untwistedness. Finally, in the special case when the twisted cube arises from the representation-theoretic data of $\lambda$ an integral weight and $\underline{w}$ a choice of word decomposition of a Weyl group element, we give two simple necessary conditions for untwistedness which is stated in terms of $\lambda$ and $\underline{w}$.

The clinical outcomes of infraspinatus rotational transfer for irreparable posterosuperior rotator cuff tears: a preliminary report

Harada, Nobuya,Ishitani, Eiichi,Gotoh, Masafumi,Shiba, Naoto Korean Shoulder and Elbow Society 2022 대한견주관절의학회지 Vol.25 No.3

Background: This study aimed to examine the preliminary clinical results of the infraspinatus rotational transfer procedure for irreparable posterosuperior rotator cuff tears. Methods: This study included 34 patients (mean age, 68.4 years). Their mean tear width and length measurements were 50.9 mm and 50.6 mm, respectively. The functional outcomes, including physician-determined and patient-reported scores, were evaluated before and at 1 year after surgery. The structural outcomes determined using the magnetic resonance imaging examination results were also assessed. Results: The clinical scores significantly improved after surgery compared with the scores before surgery: the Constant-Murley score (53.3±21.1 to 76.8±10.5), University of California at Los Angeles Shoulder score (15.6±3.6 to 27.8±6.7), American Shoulder and Elbow Surgeons Shoulder score (51.8±18.3 to 89.1±13.5), and WORC score (925.0±436.8 to 480.3±373.2) (all p<0.001). Postoperative re-tears were noted in two patients (5.9%). Conclusions: One year postoperatively, the patient's clinical scores significantly improved, with a re-tear rate of 5.9%.

Harada, Ichiro,Kim, Sung-Gon,Cho, Chong Su,Kurosawa, Hisashi,Akaike, Toshihiro Wiley Subscription Services, Inc., A Wiley Company 2007 Journal of biomedical materials research. Part A Vol.a80 No.1

<P>In this study, a simple combined method consisting of floating and anchored collagen gel in a ligament or tendon equivalent culture system was used to produce the oriented fibrils in fibroblast-populated collagen matrices (FPCMs) during the remodeling and contraction of the collagen gel. Orientation of the collagen fibrils along single axis occurred over the whole area of the floating section and most of the fibroblasts were elongated and aligned along the oriented collagen fibrils, whereas no significant orientation of fibrils was observed in normally contracted FPCMs by the floating method. Higher elasticity and enhanced mechanical strength were obtained using our simple method compared with normally contracted floating FPCMs. The Young's modulus and the breaking point of the FPCMs were dependent on the initial cell densities. This simple method will be applied as a convenient bioreactor to study cellular processes of the fibroblasts in the tissues with highly oriented fibrils such as ligaments or tendons. © 2006 Wiley Periodicals, Inc.

At the present stage, the main objective is to identify the issues related to wood, such as building structural systems, construction methods, materials used, and resource development, and to create a roadmap for future technologies to be researched and developed.

On Reduced Juxtaposition in Japanese

Harada, Yasunari 서울대학교 어학연구소 1991 語學硏究 Vol.27 No.1

Reduced juxtaposition is a construction in Japanese that is somewhat similar to non-constituent coordination in English. Syntactic and semantic rules are proposed for dealing with this ellipsis within a phrase-structure-based approach to natural language grammar description.
