Multiple Simple Sentences or a Single Complex Sentence?
Osamu Hashimoto,Tomoyo Abe,Michimasa Kanno 한국일본언어문화학회 2020 일본언어문화 Vol.53 No.-
When writing a composition, when do you use a sequence of simple sentences, and when do you use a single complex sentence instead? Grammarians have yet to clarify the norms for determining which option to choose. In this presentation, we argue that when it comes to the interchangeability of a complex sentence with a sequence of simple sentences, there is asymmetry between statements of cause/reason and those featuring a contrastive conjunction. We also argue that in the case of lengthy complex sentences, Japanese, unlike Chinese, actively uses non-restrictive noun phrase modifiers to avoid a linear sequence of adverbial (dependent) clauses.

Effects of Electric Field on Raman Spectra in SrTi16O3 and SrTi18O3
Kohji Abe,Mitsuru Itoh,Osamu Sanaka,Ruiping Wang,Takashi Akaike,Takeshi Shigenari,Tomohiko Takemoto 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1
Proton ordering phase transition of ice crystal was studied by Raman pectroscopy. The difference of the vibrational modes between Ih and XI phase were detected for the rst time in the translation region and in the libration region. Below Tc(= 72K), in the translation region a new intense peak was observed at 236 cm1 and the peak at 315 cm1 in Ih phase shifted to 325 cm1. In the libration region several new peaks were observed. Assignments of these modes are discussed from the polarization dependence.

Influence of Signal Intensity Non-Uniformity on Brain Volumetry Using an Atlas-Based Method
Masami Goto,Osamu Abe,Tosiaki Miyati,Hiroyuki Kabasawa,Hidemasa Takao,Naoto Hayashi,Tomomi Kurosu,Takeshi Iwatsubo,Fumio Yamashita,Hiroshi Matsuda,Harushi Mori,Akira Kunimatsu,Shigeki Aoki,Kenji Ino,K 대한영상의학회 2012 Korean Journal of Radiology Vol.13 No.4
Objective: Many studies have reported pre-processing effects for brain volumetry; however, no study has investigated whether non-parametric non-uniform intensity normalization (N3) correction processing results in reduced system dependency when using an atlas-based method. To address this shortcoming, the present study assessed whether N3 correction processing provides reduced system dependency in atlas-based volumetry. Materials and Methods: Contiguous sagittal T1-weighted images of the brain were obtained from 21 healthy participants, by using five magnetic resonance protocols. After image preprocessing using the Statistical Parametric Mapping 5 software, we measured the structural volume of the segmented images with the WFU-PickAtlas software. We applied six different bias-correction levels (Regularization 10, Regularization 0.0001, Regularization 0, Regularization 10 with N3, Regularization 0.0001 with N3, and Regularization 0 with N3) to each set of images. The structural volume change ratio (%) was defined as the change ratio (%) = (100 x [measured volume - mean volume of five magnetic resonance protocols] / mean volume of five magnetic resonance protocols) for each bias-correction level. Results: A low change ratio was synonymous with lower system dependency. The results showed that the images with the N3 correction had a lower change ratio compared with those without the N3 correction. Conclusion: The present study is the first atlas-based volumetry study to show that the precision of atlas-based volumetry improves when using N3-corrected images. Therefore, correction for signal intensity non-uniformity is strongly advised for multi-scanner or multi-site imaging trials.

Institutionalization of Environmental Education in Japan
Masahiro Takahashi,Osamu Abe 한국환경교육학회 2019 環境 敎育 Vol.32 No.4
In this paper, the historical process of institutionalization of environmental education will be addressed as central ideas on how to attain environmental conservation and a sustainable society in Japan. In order to clarify the figure of Japanese environmental education, an institutionalization process and some important topics related to environmental education will also be described. Primitive environmental education had occurred when miserable pollution covered in Japan. Historically it was called Kowgai education (pollution education), which was one of the educational movements. After the experience of Kowgai Education, Japanese environmental education showed discontinuation between before the 1990s and after the 1990s. It is one of the important characters when to see overall environmental education in Japan. Environmental education in Japan prior to the 1990s focused on nature and environmental problems. However, since the 1990s when global environmental problems emerged, environmental education in Japan has been continuously developed. The concept of ESD is included in the idea of environmental education when the Revised Basic Act on Education appeared in 2006. Recently, Environmental Education Promotion Law is enacted in 2011 and it is also contained the concept of ESD. Terminology issue is identified in these days, which means several terms are disordered in this field of environmental education in Japan, such as "Environmental Education" and "ESD" are both utilized various sentence and contents.
