A universal design method using 3 Point task analysis and 9 universal design items
Yamaoka, Toshiki Korean Society for Emotion and Sensibility 2002 감성과학 Vol.5 No.2
In order to examine universal design, 1 have developed two analytical methodologies based on 3P(point) task analysis: structured task analysis and task matrix analysis. I also extracted nine universal design items, namely (1) adjustment, (2) redundancy, (3) specification and function transparency, (4) feedback and (5) error tolerance, (6) effective acquisition of information, (7) ease of understanding and judgment, (8) comfortable operation, and (9) continuity of information and operation. Structured task analysis is used to uncover problems in each of the tasks constituting a job for each functionally challenged condition of users, and solutions to the extracted problems are examined in terms of the above-mentioned nine universal design items. Task matrix analysis calls for the production of a table for each task in a job. In each table, nine items form the columns, and the horizontal rows list all disability types. Then, solutions are formulated for each cell formed by the intersecting columns and rows. Using these two analysis methods, 1 have conducted a verification experiment for the universal design of a public bus. The results of the research have enabled me to propose various ,solutions from a system-based perspective, instead of coming up with the superficial and isolated solutions which are normally produced when conventional analytical methods are used.

A SUPERNOVA SEARCH WITH PUBLIC ASTRONOMICAL OBSERVATORIES IN JAPAN
YAMAOKA HITOSHI,DOI MAMORU,SHiGEYAMA TOSHIKAZU,WATANABE MASARU,YASUDA NAOKI The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
We are promoting a supernova(SN) search project with medium size (60cm-105cm) telescopes belonging to public observatories in Japan. The main purpose is to measure the SNe Ia rate, which plays an important role in the chemical and dynamical evolution of galaxies. We expect to measure the SN rate in E/SO galaxies within the $35\%$ error after 2 years run, and the longer run will give the smaller error.

This paper describes effectiveness and characteristics of 3 P(point) task analysis as a new Ergonomic and Kansei design method for extracting user demand especially. The key point in 3 P task analysis is to describe the flow of tasks and extract any problems in each task. A solution of a problem means a user demand. 3 P task analysis cal eliminate an oversight of check items by examining the users`` information processing level. The suers`` information processing level was divided into the following three stages for problem extraction: acquirement of information ---> understanding and judgment ---> operation. Three stages has fourteenth cues such as difficulty of seeing, no emphasis, mapping for extracting problems. To link analysis results to the formulation of a product concept. I added a column on the right side of the table for writing the requirements (user demand) to resolve the problems extracted from each task. The requirements are extracted by using seventh cues. Finally 3 P task analysis was compared with group interview to make the characteristics of 3 P task analysis, especially extracting user demand, clear.
Minimum-Time Guidance and Control Law for High Maneuvering Missile
Yamaoka, Seiji The Korean Society for Aeronautical and Space Scie 2009 International Journal of Aeronautical and Space Sc Vol.10 No.1
This paper deals with design procedure of online guidance and control law for future missiles that requires agile maneuverability. For the purpose, the missile with high powered side thruster is proposed. The guidance and control law for such missiles is discussed from a point of view of optimal control theory in this paper. Minimum time problem is solved for the approximated system. It is derived that bang- bang control is optimal input from the necessary conditions of optimal solution. Feedback guidance without iterative calculation is useful for actual systems. In this paper. multiple design point method is applied to design feedback gains and feed forward inputs of the guidance and control law. The numerical results show that the proposed guidance and control law has a high -performance for wide-ranging boundary conditions.

<P>The mRNA of a Chlamydomonas bZIP transcription factor is spliced by CrIRE1 under ER stress, and the resulting protein protects Chlamydomonas cells from ER stress by modulating lipid remodeling.</P><P>Endoplasmic reticulum (ER) stress is caused by the stress-induced accumulation of unfolded proteins in the ER. Here, we identified proteins and lipids that function downstream of the ER stress sensor INOSITOL-REQUIRING ENZYME1 (CrIRE1) that contributes to ER stress tolerance in Chlamydomonas (<I>Chlamydomonas reinhardtii</I>). Treatment with the ER stress inducer tunicamycin resulted in the splicing of a 32-nucleotide fragment of a basic leucine zipper 1 (bZIP1) transcription factor (<I>CrbZIP1</I>) mRNA by CrIRE1 that, in turn, resulted in the loss of the transmembrane domain in CrbZIP1, and the translocation of CrbZIP1 from the ER to the nucleus. Mutants deficient in <I>CrbZIP1</I> failed to induce the expression of the unfolded protein response genes and grew poorly under ER stress. Levels of diacylglyceryltrimethylhomoserine (DGTS) and pinolenic acid (18:3Δ5,9,12) increased in the parental strains but decreased in the <I>crbzip1</I> mutants under ER stress. A yeast one-hybrid assay revealed that CrbZIP1 activated the expression of enzymes catalyzing the biosynthesis of DGTS and pinolenic acid. Moreover, two lines harboring independent mutant alleles of <I>Chlamydomonas desaturase</I> (<I>CrDES</I>) failed to synthesize pinolenic acid and were more sensitive to ER stress than were their parental lines. Together, these results indicate that <I>CrbZIP1</I> is a critical component of the ER stress response mediated by CrIRE1 in Chlamydomonas that acts via lipid remodeling.</P>

<P><B>Summary</B></P><P>Despite a strong interest in microalgal oil production, our understanding of the biosynthetic pathways that produce algal lipids and the genes involved in the biosynthetic processes remains incomplete. Here, we report that <I>Chlamydomonas reinhardtii Cre09.g398289</I> encodes a plastid‐targeted 2‐lysophosphatidic acid acyltransferase (CrLPAAT1) that acylates the <I>sn</I>‐2 position of a 2‐lysophosphatidic acid to form phosphatidic acid, the first common precursor of membrane and storage lipids. <I>In vitro</I> enzyme assays showed that CrLPAAT1 prefers 16:0‐CoA to 18:1‐CoA as an acyl donor. Fluorescent protein‐tagged CrLPAAT1 was localized to the plastid membrane in <I>C. reinhardtii</I> cells. Furthermore, expression of CrLPAAT1 in plastids led to a > 20% increase in oil content under nitrogen‐deficient conditions. Taken together, these results demonstrate that CrLPAAT1 is an authentic plastid‐targeted LPAAT in <I>C. reinhardtii</I>, and that it may be used as a molecular tool to genetically increase oil content in microalgae.</P>
New Error Correcting Scheme for Hard Detected QAM Signal
Yamaoka, Tomaya,Yamazato, Takaya,Okada, Hiraku,Katayama, Masaaki,Ogawa, Akira 통신위성우주산업연구회 2004 Joint Conference on Satellite Communications Vol.2004 No.-
In order to achieve high speed satellite communication, we propose a new R=m-2/m error correcting scheme for hard detected $2^m$-QAM signal, where we consider m $\geq$ 6. The main focus of the paper is to improve the performance even in the case of hard-detection. As results, we found that our proposed error=correcting scheme achieves good error performance despite the hard detection and the high coding rate.

This study examined how low-level Japanese English learners‟ motivation changes throughout an English course in which English is taught through reflective teaching practice. In order to investigate students‟ motivational fluctuation, Complex Dynamic Systems Theory (CDST) was applied. CDST can measure how learners‟ motivation changes by focusing on the process of change, as opposed to whether learners‟ motivation changed or not by investigating pre- and post-data, which has been the mainstream approach in motivational research for decades. At the end of each class, a “Weekly Motivational Questionnaire” (WMQ) (Nitta, 2013; Nitta & Asano, 2010) was distributed to 14 participants, and the instructor kept a journal after the class. The materials and techniques used in this class included an American TV drama, games related to the class contents, group/pair work, and the Jigsaw Method (Aronson & Patnoe, 1997). Since the class focused on improving student listening and speaking ability, a TV drama was used as the main teaching material. Trajectory patterns were obtained using the results of the WMQ. Consequently, five motivational patterns were recognized. Through individual analyses, for instance, the importance of repeated use of tasks that are related to students‟ interests are implied. A motivational developmental sequence is also hypothesized.
