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.

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.

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.
Synthesis of spherical Prussian blue with high surface area using acid etching

<P>In this study, we report a hydrothermal synthesis method to control the shape of monodisperse PB from cube to sphere via selective acid etching. Polyvinylpyrrolidone (PVP), used as a surfactant, not only maintains a good dispersion of the particle without aggregation by stabilizing the PB particles during crystallization but also plays a key role in the etching process after mixing with strong acid. The size and shape of the resulting spherical PB particles were sensitive to the molar concentration of acid solution. Consequently, the spherical PB had a high specific surface area and the calcined PB exhibited superparamagnetic properties. The results show that the spherical PB can be utilized in applications such as magnetic-field-guided drug delivery, cell labeling, and contrast agents for magnetic resonance imaging. The chemical and physical properties of the obtained samples were characterized using X-ray diffraction, Brunauere-Emmette-Teller analysis, Raman spectroscopy, and scanning electron microscopy.

Toxicological Relevance of Transporters
Maeng, Han-Joo,Chung, Suk-Jae Korean Society of ToxicologyKorea Environmental Mu 2007 Toxicological Research Vol.23 No.1
Transporters are membrane proteins that mediate the transfer of substrate across the cellular membrane. In this overview, the characteristics and the toxicological relevance were discussed for various types of transporters. For drug transporters, the overview focused on ATP-binding cassette transporters and solute carrier family 21A/22A member transporters. Except for OCTN transporters and OATP transporters, drug transporters tend to have broad substrate specificity, suggesting drug-drug interaction at the level of transport processes (e.g., interaction between methotrexate and non-steroidal anti-inflammatory agents) is likely. For metal transporters, transporters for zinc, copper and multiple metals were discussed in this overview. These metal transporters have comparatively narrow substrate specificity, except for multiple metal transporters, suggesting that inter-substrate interaction at the level of transport is less likely. In contrast, the expressions of the transporters are often regulated by their substrates, suggesting cellular adaptation mechanism exists for these transporters. The drug-drug interactions in drug transporters and the cellular adaptation mechanisms for metal transporters are likely to lead to alterations in pharmacokinetics and cellular metal homeostasis, which may be linked to the development of toxicity. Therefore, the transporter-mediated alterations may have toxicological relevance.
