노걸대 3종 판본 내 중국어 명사 접미사의 형태론적 생산성에 대한 통시적 연구

( Maeng¸ Junghwan ) 한국중국언어학회 2021 중국언어연구 Vol.- No.95

본 논문은 원명청(元明清)대에 걸쳐 출판된 노걸대 3종 판본을 바탕으로 명사 접미사의 형태론적 생산성의 역사적 변천 과정에 관한 연구를 진행하였다. 노걸대는 당시 구어체 북방 관화를 기록한 자료로써 원대부터 청대에 이르기까지의 언어적 변화를 담고 있다. 따라서 본 연구는 노걸대 3종 판본을 코퍼스 자료로 사용하여 명사 접미사의 형태론적 생산성을 분석하였다. 형태론적 생산성은 각 명사 형태소가 생성해낼 수 있는 새로운 어휘의 종류의 수를 바탕으로 측정되었다. 분석 결과 -儿이 원대부터 청대에 걸쳐 가장 높은 생산성을 지니고 있는 것으로 판명된 반면, 명사 접미사 -子와 -們의 경우 이 기간 동안 생산성이 지속적으로 감소하는 양상을 확인할 수 있었다. 본 연구의 결과는 형태론적 생산성과 어휘화의 밀접한 관련성에 대한 실증적 근거를 제시함과 동시에 형태론적 법칙을 통해 생성된 어휘와 어휘 목록에 등록된 어휘가 서로 독립적인 영역에 속해 있음을 시사하고 있다. This study focuses on the historical change in the productivity of Chinese nominal suffixes based on three versions of Laoqida (老乞大) published in the Yuan, Ming and Qing periods respectively. Because Laoqida transcribes spoken Chinese language at the time and also reflects language change over time spanning from the Yuan to Qing period, it serves as a corpus database that allows us to examine the premodern spoken Chinese language. Using Laoqida as a corpus database, this study used hapax-based analysis to examine morphological productivity of the nominal suffixes (-zi, -er, -men) under investigation based on the number of novel expressions created by each suffix. The findings of the study show that -er remains as the most productive suffix throughout the Yuan-Qing periods whereas the productivity of -zi and -men continues to decline over the same periods. The results of the study suggest that the morphological productivity and the lexicalization of derived words are closely associated with each other. Furthermore, the study provides evidence that lexicon and morphology should be considered as two independent domains.

古佛 孟思誠 硏究

맹온재(Maeng On jae) 국립국악원 1999 국악원논문집 Vol.11 No.-

Maeng Sa-sŏng was born in 1360, the 9th year of the reign of King Kongmin of the Koryo dynasty in Songdo, the present Kaesŏng. Kobul is his pan name. His grand father was Maeng Yu and his father was Maeng Hee-do. When young, he was very bright. At the age of 27, he ranked top at the civil exam. His family had a hard time in the process of the change of the regime from Koryo to Chosun. After that, he went through a variety of the important positions including ministries. He was frugal and honestly poor. And, he served the people with his political philosophy that the people should be ruled not with a law or force but with a virtue. He also emphasized filial piety. He worked for the publication of books such as the encyclopedia of law, the history of Koryo, the annals of Taejong, the book of geography and the book of royal family tree.

CAD/CAM-assisted total joint replacement for correction of facial asymmetry caused by large osteoma of mandibular condyle

Ji Youn Maeng(Ji Youn Maeng),Jin-Young Choi(Jin-Young Choi) 대한미용의학회 2023 대한미용의학회지 Vol.7 No.1

Osteoma of mandibular condyle is uncommon benign tumor that grows slowly. Growth of condylar osteoma can cause functional and morphological problems such as facial asymmetry and malocclusion. Surgical removal and concurrent temporomandibular condyle replacement is a strategy that can resolve functional and aesthetic problems associated with large osteoma of mandibular condyle. Total joint replacement (TJR) with computer-associated surgical simulation (CASS) and computer-aided design/computer-aided manufacturing (CAD/CAM) technology can effectively and accurately rehabilitate debilitated condyle. A 52-year-old female visited department of Oral and Maxillofacial Surgery at Seoul National University Dental Hospital with a chief complaint of facial asymmetry and discomfort of left temporomandibular joint (TMJ). Radiographic and CT images showed a large bony mass at left TMJ surrounding left condylar head. Clinical examination revealed mandibular shift to right side, causing malocclusion and facial asymmetry. TJR of left TMJ with customized alloplastic condyle prosthesis and Biomet fossa was planned for the patient. Condyle was designed and fabricated using CAD/CAM. Surgical guides and occlusal splint fabricated with CAD/CAM technology was well. After 2 years, patient still showed occlusal stability with restored facial symmetry. No complications or recurrence were observed. TJR with customized alloplastic condyle and stock fossa can be an effective treatment strategy for large symptomatic condylar osteoma in restoration of normal function and aesthetics.

SnO₂ Nanoslab as NO₂ Sensor: Identification of the NO₂ Sensing Mechanism on a SnO₂ Surface

Maeng, Sunglyul,Kim, Sang-Woo,Lee, Deuk-Hee,Moon, Seung-Eon,Kim, Ki-Chul,Maiti, Amitesh American Chemical Society 2014 ACS APPLIED MATERIALS & INTERFACES Vol.6 No.1

<P>Among the various metal oxides, SnO<SUB>2</SUB> has been most widely exploited as a semiconductor gas sensor for its excellent functionalities. Models illustrating the sensing mechanism of SnO<SUB>2</SUB> have been proposed and tested to explain experimentally derived “power laws”. The models, however, are often based on somewhat simplistic assumptions; for instance, the net charge transfer from an adsorbate to a sensor surface site is assumed to occur only by integer values independent of the crystallographic planes. In this work, we use layer-shaped SnO<SUB>2</SUB> crystallites with one nanodimension (1ND-crystallites) as NO<SUB>2</SUB> gas sensing elements under flat band conditions, and derive appropriate “power laws” by combining the dynamics of gas molecules on the sensor surface with a depletion theory of semiconductor. Our experimentally measured sensor response as a function of NO<SUB>2</SUB> concentration when compared with the theoretically derived power law indicates that sensing occurs primarily through the chemisorption of single NO<SUB>2</SUB> molecules at oxygen vacancy sites on the sensor surface.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-1/am404397f/production/images/medium/am-2013-04397f_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am404397f'>ACS Electronic Supporting Info</A></P>

First Record of Epinephelus areolatus (Perciformes: Serranidae) from Korea

Maeng Jin Kim,Choon Bok Song 한국수산과학회 2010 Fisheries and Aquatic Sciences Vol.13 No.4

One specimen of Epinephelus areolatus, belonging to the subfamily Epinephelinae of the family Serranidae, was collected by a hook from commercial longline fisheries in the coastal waters of Jeju Island, Korea. This species is mostly similar to E. chlorostigma, but the former is distinguished from the latter by having larger brown spots and a white posterior margin on the caudal fin. We propose a new Korean name "Dae-moon-ba-ri" for E. areolatus.

Notes : First record of Snyderina yamanokami (Pisces: Scorpaeniformes) from Korea

( Maeng Jin Kim ),( Ui Wook Hwang ),( Choon Bok Song ) 한국수산과학회(구 한국수산학회) 2010 Fisheries and Aquatic Sciences Vol.13 No.3

This is the first report of Snyderina yamanokami, from the subfamily Tetraroginae of the family Scorpaenidae, collected in Korea. The specimen (175.3 mm long) was caught in the coastal waters of Jeju Island on a commercial longline hook on 9 September 2009. This species is characterized by the following morphological traits: 9-11 dorsal fin rays, 5-6 anal fin rays, 13-15 pectoral fin rays, 5 ventral fin rays, pectoral fin tip reaching or extending past the origin of the anal fin, palatines toothless, and four dark spots on the middle of the body. We suggest a new Korean name, "Keun-mi-yeok-chi," for S. yamanokami.

The Use of Listening Strategies among Korean Elementary Students

Maeng, Un-Kyoung The English Teachers Association in Korea 2006 영어어문교육 Vol.12 No.3

Though a large amount of research concerning listening strategies has been conducted, the strategic behaviors of younger students in this area have received less attention. This study is a follow up study of an earlier case study by the author (2006). The purpose of this study is to verify what listening strategies Korean elementary learners use in a general L2 listening situation. 213 elementary students participated in this study, and a listening strategy questionnaire was used. ANOVA, MANOVA, Correlation and Multiple Regression Analysis were used to interpret the data. The results of this study reveal that younger participants used all four types of listening strategies, cognitive, compensation, metacognitive and affective, fairly often; however, the results also show that they differ in how frequently they use each strategy according to their listening proficiency. Overall, highly proficient learners use more strategies compared to less proficient learners. High proficiency learners use compensation strategies most and cognitive strategies least. Low proficient learners use affective strategies most and compensation strategies least. Moreover, the results showed no significant grade- or gender-related strategic behaviors, and also showed that L2 listening proficiency can be a significant predictor of strategic behavior of young learners. 12% of the variance in L2 strategic behaviors was attributable to L2 listening proficiency.
