Novels include various character names, depending on the genre and the spatio-temporal background of the novels and the nationality of characters. Besides, characters and their names in a novel are created by the author's pen and imagination. As a result, any proper noun dictionary cannot include all kinds of character names. In addition, the novels translated into Korean have character names consisting of two or more nouns (such as "Harry Potter"). In this paper, we propose a method to extract noun phrases for character names and to cluster the noun phrases into coreferents for the same character name. In the extraction of noun phrases, we utilize KKMA morpheme analyzer and CPFoAN character identification tool. In clustering the noun phrases into coreferents, we construct a directed graph with the character names extracted by CPFoAN and the extracted noun phrases, and then we create name sets for characters by traversing connected subgraphs in the directed graph. With four novels translated into Korean, we conduct a survey to evaluate the proposed method. The results show that the proposed method will be useful for speaker identification as well as for constructing the social network of characters.

Background: The Fagerstrom Test for Cigarette Dependence (FTCD) (formally FTND) is widely used for measuring physical dependence on nicotine. Objective: To explore the cross cultural validity and reliability of FTCD amongst Arabic speaker cigarette consumers who chew khat leaf, a stimulant green leaf. Methods: The psychometric properties of the FTCD were assessed in a subsample (91regular cigarette smokers) of purposively selected 204 UK-resident Yemeni khat chewers recruited during random visits to khat sale outlets. Data were collected via a structured face-to-face interview. Data analyses included descriptive tests and factor analysis. Results: Two factors were obtained by a principle axis factor analysis and these were termed as urgency of restoring the level of nicotine after abstinence during sleeping and maintaining the level of nicotine during waking. The internal reliability (Cronbach's alpha coefficient) of the whole FTCD is low (.68) as well as for the two subscales (.60) and (.62) respectively. Conclusion: The psychometric properties of the Arabic version of the FTCD scale in this sample of Yemeni khat chewers who smoked regularly confirmed what has been established in other cultural settings. The findings of this study have yet to be cross validated amongst other appropriately representative sample of Arabic speakers.

본 논문은 마이크로폰을 통해 실시간으로 습득된 음성으로부터 사람의 음성 감성상태를 평상, 기쁨, 슬픔, 화남 등 4가지로 구별할 수 있는 ARM 플랫폼 기반의 음성 감성인식 시스템 구현에 관한 것이다. 일반적으로 마이크로폰으로 수신된 음성은 화자 주변의 환경 잡음과 마이크로폰의 시스템 특성 때문에 입력 음성 신호가 왜곡되고 이로 인해 시스템의 성능이 저하된다. 본 논문에서는 이러한 잡음 영향을 최소화하기 위해 비교적 단순한 구조와 적은 연산 량을 가진 이동평균(MA, Moving Average) 필터를 입력 음성의 특징벡터 열에 적용하였다. 또한, 효율적으로 감성 특징벡터를 최적화할 수 있는 SFS(Sequential Forward Selection)기법을 적용해 제안 시스템의 성능을 최적화하였으며 감성 패턴 분류기로는 SVM(Support Vector Machine)을 사용하였다. 실험 결과 제안 감성인식 시스템은 모의실험에서 약 65%, ARM 플랫폼에서 약 62%의 인식률을 보였다.

Objective: This research measured physiological and psychological effects of Vibroacoustic stimulation(VA) to scapular and sacrum of supine position on the mattress. Background: When vibroacoustic stimulation applies to human body, it has a positive influence on physiological and psychological effects by stimulating the organs, tissues and cells of whole body. Method: This experiment was conducted to 10 normal males in two conditions: no stimulation and vibroacoustic stimulation. No stimulation experiment was executed as a supine position for 30 minutes without any vibrational stimulus, while vibroacoustic stimulation was transmitted by the vibrational speaker, which uses 40Hz frequency. Subjects had a laser Doppler flowmeter probe in scapular, sacrum, and also had 8 channel electroencephalogram(EEG) measurement sensor in the scalp. Blood pressure and skin temperature were measured in two conditions with an underlying posture for 30 minutes. Additionally, blood flow rate and EEG were measured before and after for two minutes on two conditions. Results: According to the vibroacoustic stimulation, blood flow rate and skin temperature were increased, while blood pressure was decreased. When using vibroacoustic stimulation compared to no stimulation, blood flow rate went approximately two times higher, and skin temperature also higher 3~4 times. Furthermore, the relative alpha power of brain wave was significantly increased when we applied to vibroacoustic stimulation. Conclusion: This experiment tested the VAT embedded in mattress in two conditions. According to this experiment, VAT decreases blood pressure, improves not only a physiological effect on blood flow rate as well as skin temperature, but also psychological functions by increasing relative alpha power. Application: The results of the publishing trend analysis might help physiological and psychological effects of vibroacoustic stimulation.

Background and Objectives We aimed to develop a Korean version of the velopharyngeal insufficiency (VPI) speech corpus system. Subjects and Method After developing a 3-channel simultaneous speech recording device capable of recording nasal/oral and normal compound speech separately, voice data were collected from VPI patients aged more than 10 years with/without the history of operation or prior speech therapy. This was compared to a control group for which VPI was simulated by using a french-3 nelaton tube inserted via both nostril through nasopharynx and pulling the soft palate anteriorly in varying degrees. The study consisted of three transcriptors: a speech therapist transcribed the voice file into text, a second transcriptor graded speech intelligibility and severity and the third tagged the types and onset times of misarticulation. The database were composed of three main tables regarding (1) speaker's demographics, (2) condition of the recording system and (3) transcripts. All of these were interfaced with the Praat voice analysis program, which enables the user to extract exact transcribed phrases for analysis. Results In the simulated VPI group, the higher the severity of VPI, the higher the nasalance score was obtained. In addition, we could verify the vocal energy that characterizes hypernasality and compensation in nasal/oral and compound sounds spoken by VPI patients as opposed to that characgerizes the normal control group. Conclusion With the Korean version of VPI speech corpus system, patients' common difficulties and speech tendencies in articulation can be objectively evaluated. Comparing these data with those of the normal voice, mispronunciation and dysarticulation of patients with VPI can be corrected.

본 연구는 의사소통의 관점에서 고도의 설득적 언어형식을 담은 광고콘텐츠의 암묵적 의미와 그 해석 과정을 의사소통 교육과 관련하여 논의하고 동시에 현대사회의 미디어 리터러시 교육을 위한 해석적 코드를 마련하는데 논의의 목적을 가진다. 성공적인 논의를 위해 필자는 특별한 목적을 구현하는 광고콘텐츠의 서사적 내용을 일반적인 대화행위로 가정하고, 내포된 암묵적 의미 표현에 대한 규칙성이 존재함을 새롭게 문제제기로 밝혔다. 또한 현 사회의 미디어 리터러시 교육이 올바르게 진행되기 위해선 선행연구의 의사소통의 원리로 암묵적 의미에 대한 언어적 해석을 지도할 수 없음을 밝혔다. 해결방안으로 사회 문화적 공유 지식과 인지가 필수적인 해석 코드임을 확인하였다. 확장된 논의를 위해 언어사용적인 면에서 특수한 목적을 지닌 광고미디어언어를 분석대상으로 하여 그 속에 나타난 암묵적 의미의 해석 과정을 검증하였다. 필자가 임의적으로 유형화시킨 암묵적 광고언어를 분석한 결과, 화자가 설득할 의도로 암묵화한 언어적 의미는 다양한 정보 및 인지효과에 의한 분석의 틀로 대부분 미디어 리터러시 교육으로 제공될 수 있음을 확인하였다. 즉 수용자들은 미디어 언어에 내재된 암묵적 의미를 해석해 나가는 과정 속에서 글자 그대로의 해석만을 수행하지 않아야 한다. 모국어 자료 및 자신의 배경지식, 사회문화적 관습, 일반적인 공통지식 등을 포함시켜 지도한다면 효율적인 미디어 리터러시 교육의 성과를 기대할 수 있을 것이다.
