Eoarchean-Paleoproterozoic zircon inheritance in Japanese Permo-Triassic granites (Unazuki area, Hida Metamorphic Complex): Unearthing more old crust and identifying source terrranes

Horie, K.,Yamashita, M.,Hayasaka, Y.,Katoh, Y.,Tsutsumi, Y.,Katsube, A.,Hidaka, H.,Kim, H.,Cho, M. Elsevier Scientific Pub. Co., etc.] 2010 Precambrian research Vol.183 No.1

U-Pb zircon geochronology of two Permo-Triassic granites (samples OT-52 and OT-272 with ages of 229+/-8Ma and 256+/-2Ma, respectively) in the Unazuki area, Hida Metamorphic Belt, southwest Japan, revealed the presence of Eoarchean to Paleoproterozoic inheritance. Inheritance is consistent with both samples showing low zircon saturation temperatures for their bulk compositions. In OT-52, dark in CL, low Th/U zircon domains have a mean <SUP>207</SUP>Pb/<SUP>206</SUP>Pb age of 1940+/-17Ma, which is consistent with an age of 1937+/-6Ma for anatexis in the Precambrian Busan gneiss complex in Korea. Eoarchaean inherited zircons with <SUP>207</SUP>Pb/<SUP>206</SUP>Pb ages from ca. 3750 to 3550Ma are common in OT-272 but are few in OT-52, suggesting a source from rocks with affinities to those in the Anshan area in the northeast China part of the North China Craton. On the other hand, a Hida Metamorphic Belt metasedimentary gneiss into which the granites were intruded contains ca. 1840, 1130, 580, 360, 285 and 250Ma zircons (Sano et al., 2000). These ages suggest that the Unazuki Mesozoic granites did not originate from proximal Hida Metamorphic Complex rocks, but instead from unrelated rocks obscured at depth. The predominance of Eoarchean to Paleoproterozoic age components, and the marked lack of 900-700Ma components suggest that the source was the (extended?) fringe of the North China Craton, rather than from Yangtze Craton crust. The Mesozoic evolution of Japan and its linkages to northeast Asia are discussed in the context of these results.

Occupational Health Policies on Risk Assessment in Japan

Horie, Seichi Occupational Safety and Health Research Institute 2010 Safety and health at work Vol.1 No.1

Industrial Safety and Health Law (ISH Law) of Japan requires abnormalities identified in evaluations of worker health and working environments are reported to occupational physicians, and employers are advised of measures to ensure appropriate accommodations in working environments and work procedures. Since the 1980s, notions of a risk assessment and occupational safety and health management system were expected to further prevent industrial accidents. In 2005, ISH Law stipulated workplace risk assessment using the wording "employers shall endeavor." Following the amendment, multiple documents and guidelines for risk assessment for different work procedures were developed. They require ISH Laws to be implemented fully and workplaces to plan and execute measures to reduce risks, ranking them from those addressing potential hazards to those requiring workers to wear protective articles. A governmental survey in 2005 found the performance of risk assessment was 20.4% and common reasons for not implementing risk assessments were lack of adequate personnel or knowledge. ISH Law specifies criminal penalties for both individuals and organizations. Moreover, under the Labor Contract Law promulgated in 2007, employers are obliged to make reasonable efforts to ensure employee health for foreseeable and avoidable risks. Therefore, enterprises neglecting even the non-binding provisions of guidelines are likely to suffer significant business impact if judged to be responsible for industrial accidents or occupational disease. To promote risk assessment, we must strengthen technical, financial, and physical support from public-service organizations, encourage the dissemination of good practices to reduce risks, and consider additional employer incentives, including relaxed mandatory regulations.

Estimation Method of the Positions of Reinforcing Steel Bars by using Pulsed-Magnetization

Hori, Michitaka,Sana, Ryousuke,Komori, Mochimitsu 대한전기학회 2014 The Journal of International Council on Electrical Vol.4 No.4

Recently, the inspection of positions and depths of reinforcing steel bars in reinforced concrete structures is important. An electromagnetic induction method and an electromagnetic radiation radar method are used for inspection techniques of nondestructive. But, a general inspection technique also has the problem. Other techniques are actively researched now. Authors previously proposed a method of estimating position, depth and diameter of a single reinforcing steel bar by using the pulse-magnetization. In most cases reinforcing steel bars are usually found in more than one the reinforcing steel bars. Authors examined the method estimating the positions of reinforcing steel bars in more than one the reinforcing steel bars. The magnetization characteristic of the reinforcing steel bar was examined, Authors confirmed about the technique for estimating of the position of the reinforcing steel bar through the basic experiments and simulations, and report.

Recent Advances of Nutritional Physiology and Artificial Diet of the silkworm, Bombyx mori, in Japan

Horie, Yasuhiro 한국잠사학회 1995 한국잠사곤충학회지 Vol.37 No.2

Recently, the cocoon production is reducing very steeply in Japan. The main reason for this cocoon reduction is due to high labor cost and the production expense is apt to rise year by year. Accordingly, the improvement of cocoon productivity by retrenchment of the production expense is intensively required in my country. Therefore, the silkworm rearing on the artificial diet is largely expected as the innovation techniques of sericulture. Since rearing of the silkworm on artificial diets has first been achieved in 1960, and the silkworm larvae were reared throughout all the instars on artificial diets(Fukuda et al., 1960, Ito &Tanaka, 1960). The artificial diets used at this time contained 50% or more of dried, pulverized mulberry leaves as one of the main ingredients, and the composition was rather simple. When reared on these diets, larval growth and development were retarded, small cocoons appeared, and the adults laid only a small number of eggs. At first, we would like to study about nutritional requirement of the silkworm, using the chemically defined diet which prepared artificially. Subsequently, attempts were made to improve the diets by replacement of crude ingredients with possibly purer compounds, as mentioned later. Before giving the details on individual nutrient, I would like to summarize about the outline of utilization flow of various nutrients through the larval-pupal development and these daily quantitative requirements per body weight in the silkworm when they were reared on mulberry leaves.

Hori Chinatsu,Miki Hiroki,Nagae Masahiro,Yoshio Tetsuo 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1

Y-type barium ferrite was prepared by the glass-ceramic method. Glasses with composition of were prepared, and the precipitation behavior of Y-type ferrite from the glass matrix was investigated by heating glass specimens at various temperature. which is a precursor of M-type ferrite was precipitated at about 813 K and an unknown compound, phase X, was precipitated at about 850 K. M-type ferrite and Y-type ferrite started to form at about 923 K and 1103 K, respectively. The formation of Y-type ferrite was int erpreted as the result of the reaction of M-type ferrite with a melt of phase X.

Hyperthermia enhances the effect of &bgr;棺-lapachone to cause &ggr;款H2AX formations and cell death in human osteosarcoma cells

Hori, Takeshi,Kondo, Takashi,Lee, Hyemi,Song, Chang W.,Park, Heon Joo Informa UK, Ltd. 2011 International journal of hyperthermia Vol.27 No.1

<P><I>Purpose:</I> The anti-cancer effect of &bgr;棺-lapachone (&bgr;棺-lap) is positively related to the cellular activity of NAD(P)H:quinone oxidoreductase (NQO1). Heat shock has been reported to elevate cellular NQO1. The effect of heating on the NQO1 expression in human osteosarcoma cells (HOS) and the response of the cells to the combined treatment with &bgr;棺-lap and hyperthermia was investigated.</P><P><I>Materials and methods:</I> The effects of &bgr;棺-lap alone, hyperthermia alone and in combination to cause clonogenic death and apoptosis in HOS cells were elucidated. The effect of heating on the NQO1expression was evaluated with western blot analysis. The effect of &bgr;棺-lap on the cell cycle distribution was elucidated with flow cytometry and to cause DNA damage was determined by assessing the <I>&ggr;款</I>H2AX foci formation.</P><P><I>Results:</I> Treatment of HOS cells with &bgr;棺-lap at 42°째C was markedly more effective than that at 37°째C in causing clonogenic cell death. Heating caused a long-lasting up-regulation of NQO1 in the cells, and sensitised the cells to &bgr;棺-lap. The <I>&ggr;款</I>H2AX foci formation was increased immediately after &bgr;棺-lap treatment and preheating increased the &bgr;棺-lap-induced <I>&ggr;款</I>H2AX foci formation.</P><P><I>Conclusions:</I> The sensitivity of HOS cells to &bgr;棺-lap was increased not only during heating but also after heating as demonstrated by the increase in the clonogenic cell death and <I>&ggr;款</I>H2AX foci formation. The increase in &bgr;棺-lap sensitivity after heating appeared to be due to the heat-induced elevation of NQO1 activity.</P>

파워스폿 체험의 현상학: 현세이익에서 심리이익으로

HORIE Norichika 서울대학교 일본연구소 2018 일본비평 Vol.- No.18

In Japan, “power spot” refers to a place where spiritual power, energy, and strength, which are generally invisible, are strongly experienced. This word appeared in the mid of 1980s, and by the 2000s it was believed that there were many power spots in shrines. Since the “power spot” boom in 2009, propaganda for worldly profits started to appear. Previous researches focused on pointing out deviations from shinki (神気) belief through information analysis of mass media. In this article, I analyzed contents of internet blog articles on power spot experiences based on four factors – physical effect, psychological effect, parapsychological effect, and worldly profit. These visitors expressed that they received an impression that they were invited to the place of sedative actions, stimulant actions, and mysterious feelings through the senses of water, light, sound, temperature, wind, etc., and that they obtained “power” by associating it with meta-waves of electromagnetic waves or energy. Some people constituted extrasensory perceptions in their meditative state and expressed in poetic images. At first, visitors appeared as if they were pursuing for worldly profits, but in effect they were internally obtaining “psychological profits” that improved their perceptions and responses of life problems. Finally, I would like to point out that factors of shinki belief, worldly profit, and nature worship coexist in the same place by examining the example of Ōmiwa Shrine. Power spot experience may be a deviation from shinki belief, but unlike the pursuit of worldly profits, visitors seem to be able to discover authenticity through the practice of nature worship.
