韓国学習者の日本語動詞獲得モデル: 学習者総体モデルとの比較 ― 「多言語母語の日本語学習者横断コーパス」の絵描写作文を用いた検証 ―

石川慎一郎 ( Shin’ichiro¸ Ishikawa ) 한국일어교육학회 2021 일본어교육연구 Vol.- No.56

本論文では「多言語母語の日本語学習者横断コーパス」(I-JAS)に含まれる韓国学習者(KLJ)による絵描写作文を習熟度レベルごとに分析し、KLJの動詞獲得過程のモデル化を試みた。分析結果は、同コーパスに含まれる海外日本語学習者の総体(WLJ)データを分析した石川(2021)と比較された。RQ1(動詞使用量)については、習熟度別に見た場合、KLJとWLJともに逆U字型のパタンを示すことが確認された。RQ2(マーカー動詞)に関して、母語話者との比較の結果、KLJが使用できない動詞には(a)複合動詞,(b)慣用動詞、(c)否定的ニュアンスを含む動詞など、KLJのみが使用する動詞には(d)意思·意図に関する誤用、(e)文脈の不適合、(f)複合動詞要素の誤用、(g)不要な内容の言語化などが含まれ、いずれもWLJと同じパタンを示すことが確認された。RQ3(習熟度分類)については、KLJの動詞獲得がⅠ(存在動詞·移動動詞など)→Ⅱ(動詞の拡張)→Ⅲ(複合動詞成分·アスペクト成分·サ変動詞など)→Ⅳ(高度な複合動詞成分·変化動詞など)の4段階に区分され、ほぼWLJに重なることが示された。RQ4(習熟度推定)については、7種の動詞(入る·為る·見る·仕舞う·知る·来る·入れる)の使用頻度によって習熟度を63%の精度で予測できるが、予測モデルに含まれる動詞はWLJの場合とは異なることが示された。動詞獲得におけるKLJの固有特性は限定的で、KLJの特徴の大部分は日本語学習者全般の特徴であると言える。この点をふまえれば、日本語学習者コーパス研究においては、L1差よりもL2習熟度差を優先した分析が必要だと考えられる。 Using the International Corpus of Japanese as a Second Language (I-JAS), this study analyzed the picture description essays written by Korean learners of Japanese (KLJ) at different L2 proficiency levels to explore the process of their acquisition of L2 Japanese verbs. The results were compared to the verb acquisition process of the whole learners of Japanese (WLJ) reported in Ishikawa (2021). The corpus-based analyses showed that (1) an inverted U pattern existed in terms of the number of tokens/ types of the verbs used in the essays for both KLJ and WLJ, (2) when compared to the verb usage of Japanese native-speakers (JNS), some verbs were used only by JNS and others only by KLJ, and these “marker” verbs were almost the same for KLJ and WLJ, (3) KLJ’s verb acquisition process could be subdivided into four stages: 1 (existential verbs/ verbs of moving), 2 (a greater variety of verbs), 3 (composite verbs and aspectual verbs), and 4 (complex composite verbs and verbs of change), which were almost identical to the patterns for WLJ, and (4) KLJ’s L2 proficiency could be explained by the frequency of seven types of verbs (hairu, suru, miru, shimau, shiru, kuru, ireru) with 63% accuracy, though these verbs were different from a set of verbs adopted in the regression model for WLJ. These findings corroborated that KLJ’s verb acquisition pattern did not differ much from the pattern for WLJ, which may suggest the need for the Japanese learner corpus studies focusing on learners’ L2 proficiency rather than on their L1 types.

Toda, Shin-ichiro 한국광학기기산업협회 2009 光學世界 Vol.122 No.-

이번호에는 광기술컨텍트 2009년 5월호 <특집:광학기술의 한계>에서 Toda Shin-ichiro씨가 기고한 '편광소자의 광학특성의 한계' 내용을 번역하여 게재한다. 최근 노광기, 광기록을 비롯하여 레이저 가공, 광계측 등 여러 분야에 걸쳐 광원파장의 단파장화가 진행되고 있다. 이러한 상황 속에서 광학부품의 하나인 편광자의 자외화(紫外化)에 대한 필요성이 요구되고 있다. 성능적으로 밸런스가 좋은 편광자로 글랜 톰슨 프리즘을 들 수 있는데 본 고에서는 글랜 톰슨 프리즘 구조에서 파장 $\lambda$=1800nm부터 사용 가능하고 투과율도 높은 편광자와 그 제작 시의 문제점에 대해 설명하고 있다.

Submandibular sialolithiasis with CT and scintigraphy: CT values and salivary gland excretion in the submandibular glands

Purpose: Sialolithiasis is one of the most prevalent large obstructive disorders of the submandibular glands. The aim of this study was to investigate submandibular sialolithiasis with computed tomography (CT) and scintigraphy, with a particular focus on the relationship between CT values of the submandibular glands and their excretion rate. Materials and Methods: Fifteen patients with submandibular sialolithiasis who underwent CT and salivary gland scintigraphy were included in this study. The relationship between the CT values of submandibular glands with and without sialoliths and salivary gland excretion measured using salivary gland scintigraphy was statistically analyzed. Dynamic images were recorded on the computer at 1 frame per 20 seconds. The salivary gland excretion fraction was defined as A (before stimulation test [counts/frame]) / B (after stimulation test [counts/frame]) using time-activity curves. Results: The CT values in the submandibular glands with and without sialoliths was 9.9±44.9 Hounsfield units (HU) and 34.2±21.8 HU, respectively (P=.233). Regarding the salivary gland excretion fraction using scintigraphy, the A/B value in the submandibular glands with sialoliths (1.09±0.23) was significantly lower than in the submandibular glands without sialoliths (1.99±0.57, P=.000). Conclusion: Assessments of the CT values and the salivary gland excretion fraction using scintigraphy in the submandibular glands seem to be useful tools evaluating submandibular sialolithiasis.

Towards Symbiotic Machining Processes

Ichiro Inasaki 한국정밀공학회 2012 International Journal of Precision Engineering and Vol. No.

In order to achieve eco-friendly machining processes, which are becoming important issues in manufacturing, the performances of factories, machine tools, and machining processes should be adapted to allow them to perform their tasks with minimal energy consumption and emissions. This paper discusses some of the reasons why we have to pay attention to the environmental aspects of machining processes. This is followed by the introduction to some challenges to attaining sustainable manufacturing with less energy consumption, waste, and emissions. Manufacturing is a lifeline for Japan, which does not have adequate amounts of natural resources.

2D Image Construction from Low Resolution Response of a New Non-invasive Measurement for Medical Application

Ichiro Hieda,남기창 한국전자통신연구원 2005 ETRI Journal Vol.27 No.4

This paper presents an application of digital signal processing to data acquired by the radio imaging method (RIM) that was adopted to measure moisture distribution inside the human body. RIM was originally developed for the mining industry; we are applying the method to a biomedical measurement because of its simplicity, economy, and safety. When a two-dimensional image was constructed from the measured data, the method provided insufficient resolution because the wavelength of the measurement medium, a weak electromagnetic wave in a VHF band, was longer than human tissues. We built and measured a phantom, a model simulating the human body, consisting of two water tanks representing large internal organs. A digital equalizer was applied to the measured values as a weight function, and images were reconstructed that corresponded to the original shape of the two water tanks. As a result, a two-dimensional image containing two individual peaks corresponding to the original two small water tanks was constructed. The result suggests the method was applicable to biomedical measurement by the assistance of digital signal processing. This technique may be applicable to home-based medical care and other situations in which safety, simplicity, and economy are important.
