New Records of Three Paraprionospio Species (Polychaeta: Spionidae) from Korean Waters
Hisashi Yokoyama,최진우 한국해양과학기술원 2010 Ocean science journal Vol.45 No.1
The spionid polychaete Paraprionospio pinnata (Ehlers 1901) has been widely reported from Korean waters. We examined some specimens belonging to the genus Paraprionospio that had been collected from Korean waters, and identified them as Paraprionospio coora Wilson, 1990, Paraprionospio cordifolia Yokoyama, 2007 and Paraprionospio patiens Yokoyama, 2007, which are new to the fauna of Korea. The present study suggests misidentification of the specimens that have been previously reported as P. pinnata from Korean waters.
Chromium(IV)–Peroxo Complex Formation and Its Nitric Oxide Dioxygenase Reactivity
Yokoyama, Atsutoshi,Han, Jung Eun,Cho, Jaeheung,Kubo, Minoru,Ogura, Takashi,Siegler, Maxime A.,Karlin, Kenneth D.,Nam, Wonwoo American Chemical Society 2012 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.134 No.37
<P>The O<SUB>2</SUB> and NO reactivity of a Cr(II) complex bearing a 12-membered tetraazamacrocyclic <I>N</I>-tetramethylated cyclam (TMC) ligand, [Cr<SUP>II</SUP>(12-TMC)(Cl)]<SUP>+</SUP> (<B>1</B>), and the NO reactivity of its peroxo derivative, [Cr<SUP>IV</SUP>(12-TMC)(O<SUB>2</SUB>)(Cl)]<SUP>+</SUP> (<B>2</B>), are described. By contrast to the previously reported Cr(III)–superoxo complex, [Cr<SUP>III</SUP>(14-TMC)(O<SUB>2</SUB>)(Cl)]<SUP>+</SUP>, the Cr(IV)–peroxo complex <B>2</B> is formed in the reaction of <B>1</B> and O<SUB>2</SUB>. Full spectroscopic and X-ray analysis revealed that <B>2</B> possesses side-on η<SUP>2</SUP>-peroxo ligation. The quantitative reaction of <B>2</B> with NO affords a reduction in Cr oxidation state, producing a Cr(III)–nitrato complex, [Cr<SUP>III</SUP>(12-TMC)(NO<SUB>3</SUB>)(Cl)]<SUP>+</SUP> (<B>3</B>). The latter is suggested to form via a Cr(III)–peroxynitrite intermediate. [Cr<SUP>II</SUP>(12-TMC)(NO)(Cl)]<SUP>+</SUP> (<B>4</B>), a Cr(II)–nitrosyl complex derived from <B>1</B> and NO, could also be synthesized; however, it does not react with O<SUB>2</SUB>.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2012/jacsat.2012.134.issue-37/ja307384e/production/images/medium/ja-2012-07384e_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja307384e'>ACS Electronic Supporting Info</A></P>

Background: In Japan, new regulations that revise the dose limit for the lens of the eye (hereafter the lens), operational quantities, and measurement positions for the lens dose were enforced in April 2021. Based on the international safety standards, national guidelines, the results of the Radiation Safety Research Promotion Fund of the Nuclear Regulation Authority, and other studies, the Working Group of Radiation Protection Standardization Committee, the Japan Health Physics Society (JHPS) developed a guideline for radiation dose monitoring for the lens.Materials and Methods: The Working Group of the JHPS discussed the criteria of non-uniform exposure and the management criteria set not to exceed the dose limit for the lens.Results and Discussion: In July 2020, the JHPS guideline was published. The guideline consists of three parts: main text, explanations, and 26 examples. In the questions, the corresponding answers were prepared, and specific examples were provided to enable similar cases to be addressed.Conclusion: With the development of the guideline on radiation dose monitoring of the lens, radiation managers and workers will be able to smoothly comply with revised regulations and optimize radiation protection.
AVHRR MOSAIC IMAGE DATA SET FOR ASIAN REGION
Yokoyama, Ryuzo,Lei, Liping,Purevdorj, Ts.,Tanba, Sumio 대한원격탐사학회 1999 International Symposium on Remote Sensing Vol.15 No.1
A processing system to produce cloud-free composite image data set was developed. In the process, fine geometric correction based an orbit parameters and ground control points and radiometric correction based on 6S code are applied. Presently, by using AVHRR image data received at Tokyo, Okinawa, Ulaanbaatar and Bangkok, data set of 10 days composite images covering almost whole Asian region.
"Computer Programming IV" as Capstone Design and Laboratory Attachment
Yokoyama, Shoichi Korean Society for Engineering Education 2012 공학교육연구 Vol.15 No.5
A new obligatory subject, Computer Programming IV, is organized in the Department of Informatics, Faculty of Engineering, Yamagata University. The purposes of the subject are as follows: (1) Attachment to each laboratory for bachelor thesis was usually at the initial stage of the student's fourth academic year. This subject actually moves up the attachment because students are tentatively attached to a laboratory for this subject. The interval to complete their bachelor thesis is extended by half a year. (2) In each laboratory, students cooperate with each other to complete their project. The project becomes capstone design which JABEE (Japan Accreditation Board for Engineering Education) is recently emphasizing. We not only explain the introduction of this subject, but also report some case studies.
