This study explored appropriate speaking activities for speakers of different proficiency levels by measuring the changes in their brain blood flow with near-infrared spectroscopy (NIRS). Fifty adult speakers and learners of English of various proficiency levels participated in the study by undertaking four types of task: a single-speaker picture description, interview, and two paired interaction activities on an easy and a difficult topic. By objectively analyzing the collected data, the authors revealed which speaking activity facilitated brain activity, which speaking activity was suitable for which level of learner, and from which area of the brain it was possible to obtain activation data. In short, advanced language learners need to tackle more difficult tasks, while easy, patterned tasks such as the picture description and interview are more appropriate for elementary level learners. As for intermediate learners, their language learning is likely to be promoted through most of the activity types, except for the interactions on difficult topics, which were shown to decrease their brain blood flow.

Jun Negishi,Hideo Ohuchi,Kenji Yasuda,Aya Miyazaki,Nakanishi Norifumi,Osamu Yamada 대한심장학회 2015 Korean Circulation Journal Vol.45 No.1

Background and Objectives: Little information is available regarding adult patients with congenital heart disease (CHD) who needed unscheduledhospitalization (USH). This paper aims to elucidate the clinical features of adult patients with CHD requiring USH. Subjects and Methods: Study subjects included patients with CHD aged 18 years or older who were hospitalized at our facility during a5-year study period. Medical records were retrospectively reviewed and data regarding USH were collected. Patient’s background, underlyingheart disease, cause of hospitalization, and prognosis (second USH regardless of cause or death) were examined. Results: Overall, 959 CHD patients underwent a total of 1761 hospitalizations, including 145 patients who were unexpectedly hospitalized239 times. The median age at USH was 27 years old. Of the 959 patients, 54% were male. Underlying heart diseases included repaired tetralogyof Fallot (21%), single ventricular physiology after Fontan operation (17%), and Eisenmenger syndrome (12%). The causes of USH includedarrhythmia (40%), heart failure (20%), infectious disease (13%), and hemorrhage or thrombus (13%). A total of 48 patients requiredreadmission. In total, 13 patients died, including four hospital deaths. The USH-free survival rate was 77% for 1 year and 58% for 3 years. Conclusion: The rate of USH was high for adults with complicated CHD. Common causes of USH included arrhythmia, heart failure, hemorrhage-related or thrombus-related conditions and infection. These data provide the current status of medical care for adult CHD patientsin Japan and their therapeutic needs.

Relationships between L2 Speakers" Development and Raters` Perception on Fluency in Group Oral Interaction

( Junko Negishi ) 범태평양응용언어학회 2011 범태평양응용언어학회지 Vol.15 No.2

This study aimed to investigate the characteristics and developmental phenomena apparent in Japanese learners of English with their raters`` perspectives in terms of fluency which has been recognized as a major factor in judging non-native speakers`` proficiency. The following temporal indices demonstrated strong relationships with the raters`` scores on fluency: total number of syllables including/excluding dysfluency, total number of words, and total speaking time including pause time. The three indices can be useful when confined to Japanese students. With regard to pauses and hesitations, the university students exhibited results comparable to other participants; however, the locations and lengths of pauses at a phrase boundary alone gave evidence that they paused at grammatical junctures.

The Role of Demand in Adam Smith's Theory of Natural Price

Takashi Negishi 서울대학교 경제연구소 1988 Seoul journal of economics Vol.1 No.4

By the use of a simple growth model, it is shown that prices are not determined purely by technological or cost considerations and the role of demand in the determination of prices is properly recognized in Adam Smith's theory of natural prices, in which the natural rate of wage is considered to be higher in an economy with a higher rate of growth and the higher wage and the higher rate of profit can coexist. Smith's theory of falling rate of profit is defended from Ricardo's criticism.

Characteristics of Interactional Management Functions in Group Oral by Japanese Learners of English

( Junko Negishi ) 범태평양응용언어학회 2010 범태평양응용언어학회지 Vol.14 No.1

This study attempted to investigate the characteristics of interaction dynamics in a group oral interaction carried out by Japanese learners of English. The relationship between the participants` language development and interactional management functions (IMFs) was also explored. Oral performance tests in a paired or a small group have recently been introduced because the assessment of L2 learners` authentic conversational competence is considered important in the current era of globalization. Qualitative analysis showed that some characteristics, namely, modifying or developing the topic and negotiation of meaning, displayed an association with the development of the participants` language ability. More proficient speakers` dialogues of this study showed a more complex, co-constructed, and collaborative nature, with more interactions and negotiation of meaning.

Assessment Behavior and Perceptions of Raters in Paired and Group Oral Interaction

( Junko Negishi ) 범태평양응용언어학회 2015 범태평양응용언어학회지 Vol.19 No.1

The study considers the assessment of L2 English learners by trained raters in paired and group oral assessments in comparison to an individual, monologue assessment, to determine I) the degree to which raters assign pairs/groups shared (the same) scores and the degree to which raters give individual members of pairs/groups higher or lower as opposed to matching individual scores, 2) assessment tendencies by participants`` English proficiency and paring/grouping conditions, 3) individual variation among raters, and 4) the types of comments (positive, negative, or mixed) raters give participants in pair/group conditions. It was found that 1) on the whole, pair/group scores tend to be shared and lower than individual scores, 2) raters tended to assign both higher- and lower-level speakers lower scores when they are in interaction with lower-level speakers, but to assign middle-level speakers better scores in such a condition, 3) raters exhibited significant inter-rater variability, and 4) raters tended to give more negative comments when assigning lower scores and more positive comments on higher scores.

일본의 임의후견계약법(任意後見契約法)에 내재한 제도적 결함과 과제 : 임의후견계약법의 도용사례를 중심으로

네기시켄 ( Ken Negishi ) 국민대학교 일본학연구소 2022 일본공간 Vol.31 No.-

현재 일본정부는 성년후견제도 이용을 촉진하기 위한 기본계획을 세우고 있으며, 임의후견계약 남용 방지에 대해서도 검토하고 있다. 그러나 지금까지 남용 사례에 대한 연구는 그다지 이루어지고 있지 않다. 따라서 본고는 임의후견계약에 관한 판례를 유형화하고 구체적인 문제점을 파악하면서, 남용 사례를 일으키고 있는 임의후견계약법에 어떠한 제도적 결함이 있는지를 고찰하고, 그 개선책과 관련하여 운용 및 법개정 측면에서 다각적인 고찰을 시도한다. A basic plan to promote the use of the adult guardianship system is currently being formulated, in which the prevention of abuse of voluntary guardianship contracts is also considered. However, cases of abuse of voluntary guardianship contracts have not been studied in detail. This paper therefore attempts to examine what systemic defects exist in the voluntary guardianship contract law that have led to cases of abuse, and to consider remedial measures from various perspectives in terms of operation and amendment of the law, by typifying court cases concerning voluntary guardianship contracts and identifying specific problems.

박재형,Kazuaki Negishi,Deborah H. Kwon,Zoran B. Popovic,Richard A. Grimm,Thomas H. Marwick 한국심초음파학회 2014 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.22 No.3

Background: Right ventricular (RV) dysfunction in ischemic cardiomyopathy (ICM) is associated with poor prognosis, butRV assessment by conventional echocardiography remains difficult. We sought to validate RV global longitudinal strain(RVGLS) and global longitudinal strain rate (RVGLSR) against cardiac magnetic resonance (CMR) and outcome in ICM. Methods: In 57 patients (43 men, 64 ± 12 years) with ICM who underwent conventional and strain echocardiography andCMR, RVGLS and RVGLSR were measured off-line. RV dysfunction was determined by CMR [RV ejection fraction (RVEF) <50%]. Patients were followed over 15 ± 9 months for a composite of death and hospitalization for worsening heart failure. Results: RVGLS showed significant correlations with CMR RVEF (r = -0.797, p < 0.01), RV fractional area change (RVFAC,r = -0.530, p < 0.01), and tricuspid annular plane systolic excursion (TAPSE, r = -0.547, p < 0.01). RVGLSR showed significantcorrelations between CMR RVEF (r = -0.668, p < 0.01), RVFAC (r = -0.394, p < 0.01), and TAPSE (r = -0.435, p < 0.01). RVGLS and RVGLSR showed significant correlations with pulmonary vascular resistance (r = 0.527 and r = 0.500, p < 0.01,respectively). The best cutoff value of RVGLS for detection of RV dysfunction was -15.4% [areas under the curve (AUC) = 0.955,p < 0.01] with a sensitivity of 81% and specificity 95%. The best cutoff value for RVGLSR was -0.94 s-1 (AUC = 0.871, p <0.01), sensitivity 72%, specificity 86%. During follow-up, there were 12 adverse events. In Cox-proportional hazard regressionanalysis, impaired RVGLS [hazard ratio (HR) = 5.46, p = 0.030] and impaired RVGLSR (HR = 3.95, p = 0.044) were associatedwith adverse clinical outcome. Conclusion: Compared with conventional echocardiographic parameters, RVGLS and RVGLSR correlate better with CMRRVEF and outcome.
