韓國語釜山方言と日本語東京方言の外來語のアクセント

손재현 ( Jae Hyun Son ) 한국일어교육학회 2015 일본어교육연구 Vol.0 No.31

本稿では、韓國語と日本語のように高低アクセントとされる言語の類型的硏究及び對照言語學的考察として、日本語の東京方言と韓國語の釜山方言のアクセント體系を提示した上で、兩言語の外來語のアクセント型の特微を中心に考察を進める。後來、日本語の東京方言の外來語のアクセントについては、多數の硏究が行われ、いわゆる「─(マイナス)3規則(アクセント核が右から3番目に置かれる)」で說明されてきた。一方、慶尙道方言の硏究は少ないものの、いずれも音節構造との關連から論じられており、音節構造が大きくアクセントに關我於しているという結論を出している。しかし、筆者の硏究からみると、それだけでは決まらない例が多數存在することがわかった。本稿は慶尙北道の大邱方言·慶州方言に引き續き、慶尙南道の釜山方言を對照に先行硏究の結論を驗證したもので、その結果、釜山方言も慶尙北道の大邱方言·慶州方言と同樣、音節構造だけではアクセント型を予測しきれないところが多いことがわかった。 This paper compares the loanwords accent of the Tokyo dialect of Japanese and that of Pusan dialect in Korean. In the present paper, evidence for this interpretation will be given, along with the structure of the Pusan dialect loanwords accent and a comparison with it and that of Tokyo. Tokyo dialect has two oppositions for onemora words, three oppositions for twomora words, and so on. It can be represented as Pn=n+1, where"Pn" represent the number of prosodemes for the accentual unit "n" In the Tokyo accent type, there are nkernel positions, plus a kernel less type (indicated with an = sign; the . sign indicates unaccented), for a total of n+1. The default accent of loanwords of Tokyo dialect are -③ pattern (antepenultimate). The present paper examines on the basis of the data collected by the author. The conclusion by Kenstowicz & Sohn (2001) (hereafter K & S(2001)) and Do (2014) that the accent of loanwords in the Pusan dialect is determined by their syllabic structure. Those conditions are: 1) if the final consonant cluster of the original word are resolved by two inserted vowels, those vowels are without accent; 2) the heavy syllables caused by liquid gemination are not counted as heavy. Furthermore, as regards two or five syllable words갂 the principle holds only for about 60% of cases. There is no correlation between the syllabic structure and accent as regards monosyllabic words since the accent remains the same even if the syllabic structure is altered by the addition of a particle. From the above discussion the following points in Do (2014) are criticized: A heavy syllable (CVC) must be high; if the final two syllables are light, then a (default) high is assigned to the penultimate syllable. In addition, a Light-Light-Heavy takes a final H which spreads back to the peninitial syllable. These simple principles account for over 90% of the data in all syllable profiles except for Heavy-Heavy. Thus the present paper critically examines the applicability of the two conditions on the segmental structure of the original wor d the prerequisites of the discussion of Do (2014), as well as the level of knowledge of the original words in the acquisition of loanwords by the dialect speakers.

借用語の音韻構造とアクセント

The present paper examines on the basis of the data assembled by the author the conclusion by Kenstowicz & Sohn (2001) that the accent of loanwords in the Gyeongsang dialect is determined by their syllabic structure. As a result it is shown that the highest average of the application of the K & S's principle is about 70% as regards three or four syllable words. This average is only achieved when the following two conditions regarding the original word of borrowing are taken into account. There is no correlation between the syllabic structure and accent as regards monosyllabic words, since the accent remains the same even if the syllabic structure is altered by the addition of a particle. The present paper thus critically examines the applicability of the two conditions concerning the segmental structure of the original word, the prerequisites of the discussion of K & S (2001), as well as the level of knowledge of the original words in the acquisition of loanwords by the dialect speakers.

무선 센서망에서 생체시스템 기반의 전송노드 선택 및 다중 채널 전송 알고리즘

무선센서 네트워크(WSNs)는 일반적으로 수많은 센서노드들이 배치되어 데이터를 전송하며, 불필요한 데이터 전송으로 인해 에너지 낭비를 초래한다. 기존의 연구들은 주로 에너지 소모문제를 해결하는데 집중되었다. 하지만 실시간으로 정보전송이 필요한 어플리케이션에 대해서는 지연 보장 역시 고려되어야 한다. 본 논문은 생체시스템을 모방하여 무선센서망에서 에너지의 소모와 연시간을 줄이기 위한 BISA(Bio-inspired Scheduling Algorithm)를 제안한다. BISA는 에너지 효율성이 높은 라우팅경로를 탐색하고 다중채널을 이용해 데이터 전송경로를 다중화함으로써 데이터 전송을 위한 에너지소모와 지연시간을 최소화한다. 실험결과를 통해 제안한 알고리즘의 기존방식 보다 적은 에너지를 사용하며 동시에 요구지연 시간을 보장함을 확인한다. WireWireless sensor networks(WSNs) are generally comprised of densely deployed sensor nodes, which causes highly redundant sensor data transmission and energy waste. Many studies have focused on energy saving in WSNs. However, delay problem also should be taken into consideration for mission-critical applications. In this paper, we propose a BISA (Bio-Inspired Scheduling Algorithm) to reduce the energy consumption and delay for WSNs inspired by biological systems. BISA investigates energy-efficient routing path and minimizes the energy consumption and delay using multi-channel for data transmission. Through simulations, we observe that the BISA archives energy efficiency and delay guarantees.

센서 네트워크에서 기본적으로 고려되어야 하는 것은 센서 노드의 에너지 소모 문제이다. 이를 해결하기 위해 많은 연구들이 진행되어 왔지만 에너지 소모 문제와 더불어 트레이드오프 관계를 갖는 지연 문제도 간과할 수 없는 부분이다. 본 논문은 생체시스템을 모방하여 무선 센서망에서 에너지의 소모와 지연시간을 줄이기 위한 BISA(Bio-inspired Scheduling Algorithm)를 제안한다. BISA는 에너지 효율성이 높은 라우팅 경로를 탐색하고 다중채널을 이용하여 데이터 전송의 경로를 다중화하여 데이터 전송을 위한 에너지 소모와 지연시간을 최소화한다. 모의실험을 통해 제안한 방식이 효율적으로 에너지를 소모함과 동시에 요구지연시간을 보장함을 확인한다. The energy consumption problem should be taken into consideration in wireless sensor network. Many studies have been proposed to address the energy consumption and delay problem. In this paper, we propose BISA(Bio-inspired Scheduling Algorithm) to reduce the energy consumption and delay in wireless sensor networks based on biological system. BISA investigates energy-efficient routing path and minimizes the energy consumption and delay using multi-channel for data transmission by multiplexing data transmission path. Through simulation, we confirm that the proposed scheme guarantees the efficient energy consumption and delay requirement.

In this paper, we described a design and implementation of a sensor node for environmental monitoring. The main focus of design for sensor nodes is to isolate MCU for treating sensors from the RF module for considering various communication environment. The second is to make the interface between MCU and varity of sensor. In addition, we choose a narrow band communication module, ccl020, for the admittance of Korea government communication law. We also use a uC/OS-Ⅱ as an operating system which is famous for 8bit MCUs. We showed that the communication performance is sufficient to use the communication module in a out-door environment through several experiments in that it is possible to transmit between 100m distance through experiments in a mountain.

손재현,김제홍,Son, Jae-Hyun,Kim, Je-Hong 대한전자공학회 1999 電子工學會論文誌-T Vol.t36 No.4

본 논문에서는 FLC의 적응능력에 대한 단점과 제어규칙 도출의 어려움을 극복하기 위하여 모델기준 적응 퍼지제어기(MRAFC)를 제안하였다. MRAFC는 단순퍼지제어기와 플랜트로 구성된 내부 피드백 루프와 단순 퍼지제어기의 제어규칙을 동조시키는 외부 루프로 구성된다. 기준모델은 기준입력에 대해 전체 제어시스템에 요구되는 제어성능을 특성화하고 수량화하는 퍼지제어기 설계기준으로 사용되었다. 그리고 적응 매카니즘은 FLC 제어규칙을 동조하는 역할을 수행한다. 제안한 알고리즘의 성능은 DC 서보 전동기에 대한 실험에 의해 검증되었다. In this paper, model reference adaptive fuzzy controller (MRAFC) was proposed in order to overcome the difficulty of extracting rules and defects of the adaptation performance in the FLC. MRAFC comprised inner feedback loop consisting of the FLC and plant, and outer loop consisting of an adaptation mechanism which was designed for tuning a control rule of the FLC. A reference-model was used for design criteria of a fuzzy controller which characterizes and quantizes the control performance required in the overall control system. Tuning control rules of FLC is performed by the adaptation mechanism. The performance of proposed algorithm was verified through experiment for the DC servo motor.

1919년 천진총상회의 네트워크와 사회적 역할

1919年到現在爲止,以天津爲中心,天津總商會在天津的各團體之間的網絡和地區的社會作用進行分析。 商會的成立過程和作用上,得到了學述界的關注,但天津地區在內的學生聯合會網絡,沒有對各界進行任何硏究 。往往關注消겁力量的商會, 來强調現有的軟弱、妥協的性格。在不同的硏究中,수然提及天津總商和地區性差別和積겁的方面,但停留在定性問題。靈外,學生爲代表的聯合會흔難조到與各界聯合在葛藤。本硏究在天津爲總商會中心,深入分析硏究學述界和政府各界的關系和地區的作用。 5.4時期在津各界人士保호和回收的學生的權利,在巴黎講和會議時拒絶첨名,要求징瓣賣國賊等猛烈的愛國活動。天津地區的學生們馬上呼應,向政府提出抗議,通電,他們去街上散發傳單或集會,進行罷課演講和街頭游行示威。 天津的工人也展開了,罷工各地商人領導的組織的天津代表香港總商會也相互間的聯系, 5月7日巴黎會議上,出席的代表陳熙祥,王正延,고위운發表聲明:一定要학保靑島領土得到完整。 此外, 6月7日,天津總商會的理事會,進行了討論關于天津的市場情況影향的問題擧行了罷市。6月8日,天津的學生一千多人在街頭示威結束后,學生代表諶志篤和馬駿,總商會會長葉登榜(葉蘭舫)和副會長卞月庭進行面談,提出宣布恢復商界經營。天津總商會代表立刻召開會議,討論要三四天,但學生代表覺得中國的情況十分危急,如果在危亡時刻우우豫豫的不去想보救方法而是一再的進行敷衍。最終,雙方的代表在6月9日,理事會강在天津總商會擧行和討論罷市 問題。學生代表馬駿立刻反駁,一邊對于商會的決斷表示明학的反對態度,一邊在公民大會上通報批評商會的決定內容。最終, 在6月10日 北京政府通電指責天津總商會決定罷市的行爲 違反民意。 天津總商會的罷市消息政府的態度起到了決定的影향。爲什요天津會危及到北京?如果那里數十万的工商界全部進行罷工因爲直接威脇到北京的商家。就在這危急時刻北洋政府緊急派遣曾毓雋說服總商會開市。在政府的施加壓力和商會的長時間罷市우損嚴重原因宣布復市。少數的商人們不服從商會的決定任然繼續罷市。由于這次天津總商會的罷市中,內部意見的不統一反復的罷市和復市事態的責任,提出了對于正副會長사任的?理。工商界的代表們對于天津總商會在天津發生的各種問題파脫不了基本的事態減弱和과大。那些經濟上的直接損失和那些忍受切實的痛苦,社會秩序穩定爲借口的原因政府當局的壓力也不可回避。
