Miwa Takai 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

This study proposes extracting method of characteristic posture so that an observer can detect speedily the threat of crime in enormous numbers of dynamic image shot by surveillance camera. This method measures human movement using Motion Quantity, and shows active state between 0.0 and 1.0 in numeric evaluation. We can know how much active state person acts in his/her behavior objectively. In addition, the difference between successive Motion Quantities denotes the magnitude of the change of active state. And, if the amount combining them is large, this method extracts the human pose as characteristic posture.

A Source-Related Approach for Discussion on Using Radionuclide-Contaminated Materials in Post-accident Rehabilitation

Miwa Kazuji,Iimoto Takeshi 대한방사선방어학회 2023 방사선방어학회지 Vol.48 No.2

Background : In the process of discussion on the possibility of using radionuclide-contaminated soil and debris generated by radiation disasters , a strategy for the proper management of radia- tion exposure protection while considering the source of the contaminated materials is neces- sary. JRPR Materials and Methods : The radiological protection criteria that are likely to be applied to the source-related approach based on the International Commission on Radiological Protection recommendations and the International Atomic Energy Agency safety standards are summa- rized . We proposed five interpretations of radiation protection to contribute to the promotion of discussion on the possibility of using a part of low-level-radionuclide-contaminated soil and de- bris in the post-accident rehabilitation . Interpretations I to III are based on the idea of “using a reference level to protect the public in post-accident rehabilitation ,” whereas IV and V are based on the idea of “using the dose constraint to protect the public in the post-accident rehabilitation when the sources are handled in a planned activity.” The former idea is subdivided into three based on the definition of the source , which is managed by the reference level , and the latter idea is divided into two depending on whether or not additional dose from using contaminated materials is deemed acceptable . Results and Discussion : To confirm the applicability of the five interpretations presented , we suggested the concrete values of protection criteria via two feasible cases . In this case study, we proposed radiation protection by the dose constraint based on the Interpretation IV and chose 1 mSv/yr for the public and 20 mSv/yr for workers dealing with radionuclide-contaminated ma- terials . Conclusion : We concretely and systematically demonstrated how the concept of radiation pro- tection can be applied to the process of discussion on the possibility of using radionuclide-con- taminated materials within the framework of an international system of protection . This study’s findings can provide necessary information to discuss the possibility of using radionuclide-con- taminated materials as an alternative option for recovery and reconstruction after a radiation di- saster from the viewpoint of radiation protection .

Innate, adaptive, and cell-autonomous immunity against Toxoplasma gondii infection

Miwa Sasai,Masahiro Yamamoto 생화학분자생물학회 2019 Experimental and molecular medicine Vol.51 No.-

Hosts have been fighting pathogens throughout the evolution of all infectious diseases. Toxoplasma gondii is one of the most common infectious agents in humans but causes only opportunistic infection in healthy individuals. Similar to antimicrobial immunity against other organisms, the immune response against T. gondii activates innate immunity and in turn induces acquired immune responses. After activation of acquired immunity, host immune cells robustly produce the proinflammatory cytokine interferon-γ (IFN-γ), which activates a set of IFN-γ-inducible proteins, including GTPases. IFN-inducible GTPases are essential for cell-autonomous immunity and are specialized for effective clearance and growth inhibition of T. gondii by accumulating in parasitophorous vacuole membranes. Recent studies suggest that the cell-autonomous immune response plays a protective role in host defense against not only T. gondii but also various intracellular bacteria. Moreover, the negative regulatory mechanisms of such strong immune responses are also important for host survival after infection. In this review, we will discuss in detail recent advances in the understanding of host defenses against T. gondii and the roles played by cell-autonomous immune responses.

Albumin-Bilirubin Score Predicts Tolerability to Adjuvant S-1 Monotherapy after Curative Gastrectomy

Miwa, Takashi,Kanda, Mitsuro,Tanaka, Chie,Kobayashi, Daisuke,Hayashi, Masamichi,Yamada, Suguru,Nakayama, Goro,Koike, Masahiko,Kodera, Yasuhiro The Korean Gastric Cancer Association 2019 Journal of gastric cancer Vol.19 No.2

Purpose: Due to adverse events, dose reduction or withdrawal of adjuvant chemotherapy is required for some patients. To identify the predictive factors for tolerability to postoperative adjuvant S-1 monotherapy in gastric cancer (GC) patients, we evaluated the predictive values of blood indicators. Materials and Methods: We analyzed 98 patients with pStage II/III GC who underwent postoperative adjuvant S-1 monotherapy. We retrospectively analyzed correlations between 14 parameters obtained from perioperative routine blood tests to assess their influence on the withdrawal of postoperative adjuvant S-1 monotherapy, within 6 months after discontinuation. Results: Postoperative adjuvant chemotherapy was discontinued in 21 patients (21.4%) within 6 months. Univariable analysis revealed that high preoperative albumin-bilirubin (ALBI) scores had the highest odds ratio (OR) for predicting the failure of adjuvant S-1 chemotherapy (OR, 6.47; 95% confidence interval [CI], 2.08-20.1; cutoff value, -2.696). The high ALBI group had a significantly shorter time to failure of postoperative adjuvant S-1monotherapy (hazard ratio, 3.48; 95% CI, 1.69-7.25; P=0.001). Multivariable analysis identified high preoperative ALBI score as an independent prognostic factor for tolerability (OR, 10.3; 95% CI, 2.33-45.8; P=0.002). Conclusions: Preoperative ALBI shows promise as an indicator associated with the tolerability of adjuvant S-1 monotherapy in patients with pStage II/III GC.

Production of wh-questions by Japanese EFL learners: Preliminary classroom data collection

Miwa Morishita,Yasunari Harada 경희대학교 언어정보연구소 2015 언어연구 Vol.32 No.S

High School Course of Study for English set forth by the Japanese Ministry of Education started emphasizing communication and communicative approach around the year 1990. ​In recent years, acquisition of communicative competence has become the most important objective of English language education in Japan as globalization affects diverse aspects of governmental and enterprise sectors of the Japanese society. On the other hand, while asking the right questions at the right time is an integral part of effective oral interactions, Japanese EFL learners experience processing and other difficulties in doing so. First, in classroom situations, students are generally discouraged from asking the teacher, and each other, any direct questions. Second, this leads to a general lack of communicative intelligence among those students in coming up with interesting things to ask. Third, producing English question sentences on the fly poses non-negligible processing difficulties for Japanese EFL learners. In Japanese, question sentences are formed simply by adding the question marker "ka" at the end of a sentence without changing the word order. In contrast, construing and constructing question sentences in English involves a variety of syntactic and morphological processing, resulting in a higher cognitive load compared to corresponding statement sentences. In this study, we will report on the results of one of a series of data collection efforts conducted in 2013, in which Japanese university students with diverse proficiency levels were asked to produce or reproduce English statement sentences and wh-questions based on visually or aurally presented English sentences. The results show that students had more difficulty when they were asked to convert statement sentences into wh-questions than when they were asked to simply reproduce the sentences that were presented. However, their average rates of correct answers improved in the course of investigation, possibly showing implicit learning. (Kobe Gakuin UniversityㆍWaseda University)

How syntactic processing training affects oral production of elementary level Japanese EFL learners

( Miwa Morishita ),( Tomoko Yamamoto ) 경희대학교 언어연구소 2013 언어연구 Vol.30 No.3

For EFL learners, especially elementary level learners, the initial step in language production is to combine several words into sentences. This study reports the results of classroom research aiming to facilitate oral production of elementary level Japanese EFL learners through syntactic processing training. University freshmen in five English classes which use CALL facilities engaged in a 15-minute training at the beginning of each lesson over a total of ten lessons. The training consisted of two types of tasks rearranging shuffled word groups, based on a hypothesis that such training might lead to better automatized language production. In the first half of the training, the written task, the students looked at four to five shuffled word groups and decided the correct order. In the second half of the training, the spoken task, they listened to three shuffled word groups and orally rearranged them into correct sentences. In working out such tasks, the test takers should access vocabulary in their mental lexicon, remember the shuffled word groups they listened to, and rearrange them into correct sentences, which might impose them a high cognitive load and can lead to automatized language production. The data of 88 students who engaged in such training were compared with those of 29 students who did not at both the pre-test and the post-test stages. It was found that although both the experimental and the control groups significantly increased their scores in the written task, only the experimental group significantly increased their scores in the spoken task. The results show that training as a whole seems to have had a positive effect on the students` oral production.
