《蒙古字韵》的八思巴字韵母系统研究

AN YINGJI 한국알타이학회 2020 알타이학보 Vol.0 No.30

Menggu Ziyun (蒙古字韻) is a book in which Phags-pa script, a new Mongolian script is transliterated by Chinese scripts in the 13th century. It reflects the phonology system of Ancient Mandarin, which is a transition period between Middle Chinese and Early Mandarin. This paper can be divided into two parts. Firstly, this paper aims at establishing a new transliteration system for Phags-pa, especially for ꡦ(e) and ꡠ(ė) which have been transliterated to be ꡦ(ė) and ꡠ(e) based on previous studies. Also, a combination of two vowels ꡦꡡ(ö) or ꡊꡟ(ü) can be analyzed to be a rounded vowel. Secondly, I analyzed different rhymes of Phags-pa scripts in Menggu Ziyun, by considering the influences from contacts of different languages. and then compared them with Middle Chinese and Early Mandarin. Through the comprehensive analysis of diachronic changes happened to Chinese and the influences of Mongolian, this paper aims at constructing the phonological system of Anciet Mandarin.

언어접촉과 시기층위 - 侵韻字의 중세 한국한자음의 모음을 중심으로 -

AN YINGJI 국어학회 2015 국어학 Vol.75 No.-

한국한자음은 한국어와 중국어의 언어접촉에 의한 산물이며 일종의 언어변체(言語變體)이다. 한중언어접촉에서 한국어는 주로 차용을 받아들이는 차입어(借入語) 위치에 있고 중국어는 차용어를 제공하는 차출어(借出語) 위치에 있다. 차입어와 차출어는 언어접촉 과정의 양 끝에 위치한다. 언어접촉 과정은 크게 두 단계로 나눌 수 있으며 첫 단계는 이중언어화자의 전달단계이고 두 번째 단계는 순수모어화자의 차용단계이다. 그리고 단계별로 서로 다른 체계의 언어변체가 존재하는데 첫 단계의 언어변체는 직역음(直譯音)이고 두 번째 단계의 언어변체는 한자음(漢字音)이다. 직역음은 공시적 성격을 띠고 한자음은 통시적 성격을 띠며 직역음은 중국어와 직접 역사비교가 가능하지만 한자음은 중국어와 한국어가 융합되어 있어 직접 중국어와 역사비교를 할 수 없다. 그러나 만약 한자음 내에서 한국어 영향을 제거하고 나면 중국어음이 남게 되며 이 또한 직역음 성격을 띠게 되면서 중국어와 직접 역사비교가 가능하게 된다. 즉, 이때의 직역음은 중국어음운사 어느 시기의 층위와 대응하는지 고찰이 가능하게 된다. 본고는 이러한 한자음 내의 직역음을 직역음2라고 불렀으며 侵韻字의 모음을 예로 들어 직역음2의 분리와 시기층위의 구체적인 양상을 보여주었다. 분석 결과, 해당 韻 한자들의 한자음 모음에서 ‘ㆍ>ㅡ’와 ‘ㅣ’의 대립만이 시기층위로 볼 수 있었으며 일부 상고음 층위가 보이는 예가 있는가 하면 상고음 혹은 중고음 층위의 가능성이 모두 열려 있는 예도 있었고 중고음에서 근대음의 과도기로 보이는 예도 있었다.

『洪武正韻譯訓』 훈민정음 표기 ‘ᅨ’의 음운론적 대응

AN YINGJI 구결학회 2012 구결연구 Vol.29 No.-

The finals of some syllables in 齊(Je) rhyme group of Hongmujeongun(洪武正韻) are transcribed as ‘ㅖ’ in Hongmujeongun Yeokhun(洪武正韻譯訓, simply Yeokhun), in contrast to the reconstructed /i/ sound of the contemporary historical phonology. This apparent incongruity is a consequence of the existence of doublets(重紐). In Hongmujeongun, unlike other rhyme dictionaries(韻書), even the tongue and tooth sounds(舌齒音) have doublets, and difference between doublet words and non-doublet words is associated with medials and main vowels. In this paper, with close observation of doublets of Hongmujeongun, it is revealed that most words in Je group had high vowel /ɨ/ as its main vowel and some others mid vowel /ɛ/ instead. Actually, the 'ㅖ'-transcribed Je words in Yeokhun are only matched to the doublet words with /ɛ/. This is not because the lack of consistency of the authors of Yeokhun, but because Hongmujeongun's violence of the general rules of rhyme dictionary. In conclusion, although the authors of Yeokhun followed mainly Hongmujeongun's classification system, they tried to go beyond the simple one-to-one transcription and made up for the weakness of Hongmujeongun with care and knowledge. 중국 운서 『洪武正韻』의 齊h韻에 대한 『洪武正韻譯訓』의 훈민정음 표기는 ‘ㅖ’이지만 중국음운학계 齊h韻의 재구음은 /i/이다. 이러한 차이는 重紐h韻이 존재하기 때문이다. 『洪武正韻』에서의 重紐h韻은 전통적인 重紐와 달리 舌齒音에서도 나타나며 그 차이는 개음과 모음 등 다양하게 나타난다. 본고는 重紐h韻에 대한 세밀한 관찰을 통하여 『洪武正韻』의 齊h韻은 고모음 /ɨ/가 주를 이루는 가운데 중모음 /ɛ/도 산재되어 있다는 것을 발견하였다. 훈민정음 표기 ‘ㅖ’는 실제로 산재되어 있는 중모음 /ɛ/의 重紐h韻과만 음운적으로 대응될 수 있다. 하지만 이를 『洪武正韻譯訓』의 한계로 보기보다는 우선 중국 운서 『洪武正韻』이 운서로써 갖추어야 할 기본적인 규칙을 잘 지키지 않는 운서였다는 것을 전제로 해야 할 것이다. 당시 『洪武正韻譯訓』의 편찬자들은 기본적으로 『洪武正韻』의 체재를 따르는 한편, 최대한 『洪武正韻』의 부족한 점을 보완하며 체계적으로 정리하기 위해 많은 노력을 하였음을 알 수 있다.

Fault Diagnosis of High Voltage Circuit Breaker Based on Multi‑classifcation Relevance Vector Machine

Yingjie Zhang,Yuan Jiang,Yan Chen,Ying Zhang 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.1

The high voltage circuit breaker’s fault as an important form of electrical contact fault in the power system, which is extremely difcult to diagnose under the condition of small fault dataset. This paper proposes a fault diagnosis method based on multiclassifcation relevance vector machine for high voltage circuit breakers. To make up with the scarcity of the sample fault data in classifying the features of the high voltage circuit breakers, a multi-classifcation relevance vector machine algorithm is designed on the basis of “One-Against-One” multi-classifcation model, and tested by public data-sets to verify the good generating performance of this algorithm on small sample data-sets. Then, the time and the currents features are extracted from the closing coil current information of the high voltage circuit breaker to form fault eigenvector. Consequently, numerous two-classifcation relevance vector machine models were trained and then tested for the optimality of the acquired parameters. The results show that the proposed algorithm can efectively identify many faults of circuit breaker and has better classifcation accuracy than BP neural network and Support Vector Machine under conditions of small sample data.

Cross-Layer Cooperative Scheduling Scheme for Multi-channel Hybrid Ubiquitous Sensor Networks

Yingji Zhong,Qinghai Yang,곽경섭,Dongfeng Yuan 한국전자통신연구원 2008 ETRI Journal Vol.30 No.5

The multi-scenario topology of multi-channel hybrid ubiquitous sensor networks (USNs) is studied and a novel link auto-diversity cross-layer cooperative scheduling scheme is proposed in this paper. The proposed scheme integrates the attributes of the new performance evaluation link auto-diversity air-time metric and the topology space in the given multi-scenario. The proposed scheme is compared with other schemes, and its superiority is demonstrated through simulations. The simulation results show that relative energy consumption, link reception probability, and end-to-end blocking probability are improved. The addressing ratio of success with unchanged parameters and external information can be increased. The network can tolerate more hops to support reliable transportation when the proposed scheme is implemented. Moreover, the scheme can make the network stable. Therefore, the proposed scheme can enhance the average rate performance of the hybrid USN and stabilize the outage probability.

An Integrated Approach of Wavelet Techniques and Time Series Analysis in Eliminating MEMS Inertial Gyro Stochastic Error

Yingjie Hu,Lu Xiong 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10

The accuracy of MEMS inertial sensors is affected by stochastic errors. The stochastic error of a MEMS inertial gyro consists of high frequency and low frequency components. Low frequency part is characterized by correlated noise and can be modeled by means of random process error model while the high frequency part cannot due to its white noise characteristics. An integrated method of wavelet de-noising and time series analysis is proposed in this paper: First, wavelet de-noising is employed to dispose of the high frequency noise and then time series analysis combined with Sage-Husa adaptive Kalman filter is utilized to eliminate the low frequency noise. An experiment using IMU ADIS16445 is conducted. Through Allan variance analysis, two main random noise parameters are notably diminished by almost 10 times. Results show that this proposed method is effective in suppressing MEMS gyro stochastic noise.

Theoretical Analysis and Control of DC Neutral-point Voltage Balance of Three-level Inverters in Active Power Filters

Yingjie He,Jinjun Liu,Jian Tang,Zhaoan Wang,Yunping Zou 전력전자학회 2012 JOURNAL OF POWER ELECTRONICS Vol.12 No.2

In recent years, multilevel technology has become an effective and practical solution in the field of moderate and high voltage applications. This paper discusses an APF with a three-level NPC inverter. Obviously, the application of such converter to APFs is hindered by the problem of the voltage unbalance of DC capacitors, which leads to system instability. This paper comprehensively analyzes the theoretical limitations of the neutral-point voltage balancing problem for tracking different harmonic currents utilizing current switching functions from the space vector PWM(SVPWM)point of view. The fluctuation of the neutral point caused by the load currents of certain order harmonic frequency is reported and quantified. Furthermore, this paper presents a close-loop digital control algorithm of the DC voltage for this APF. A PI controller regulates the DC voltage in the outer-loop controller. In the current-loop controller, this paper proposes a simple neutral-point voltage control method. The neutral-point voltage imbalance is restrained by selecting small vectors that will move the neutral-point voltage in the direction opposite the direction of the unbalance. The experiment results illustrate that the performance of the proposed approach is satisfactory.
