대역사전의 구축은 저자원 언어쌍 간의 기계번역의 품질을 높이는데 있어 중요하다. 대역사전 구축을 위해 기존에 제시된 방법론 중 단어 임베딩을 기반으로 하는 방법론 대부분이 영어-프랑스어와 같이 형태적 및 구문적으로 유사한 언어쌍 사이에서는 높은 성능을 보이지만, 영어-중국어와 같이 유사하지 않은 언어쌍에 대해서는 그렇지 못하다는 사실이 널리 알려져 있다. 본 논문에서는 단어 임베딩을 기반으로 부트스트래핑을 통해 대역사전을 구축하는 방법론을 제안한다. 제안하는 방법론은 소량의 seed 사전으로부터 시작해 반복적인 과정을 통해 대역사전을 자동으로 구축하게 된다. 이후, 본 논문의 방법론을 이용해 한국어-영어 언어쌍에 대한 실험을 진행하고, 기존에 대역사전 구축 용도로 많이 활용되고 있는 도구인 Moses에 사용된 방법론과 F1-Score 성능을 비교한다. 실험 결과, F1-Score가 약 42%p 증가함을 확인할 수 있었으며, 초기에 입력해준 seed 사전 대비 7배 크기의 대역사전을 구축하였다.

This study aims to acoustically analyze Korean language characteristics and convert these findings into musical elements, providing foundational data for evidence-based music-language rehabilitation. We collected voice data from thirty men and thirty women aged 19-25, each providing six-syllable prosodic units composed of two accentual phrases, including both declarative and interrogative sentences. Analyzing this data with Praat, we extracted syllabic acoustic properties and conducted statistical analyses based on acoustic properties, sentence type, gender, and particle presence. Significant differences were found in syllable frequency and duration based on accentual phrases and prosodic units (p < .001), with interrogative showing higher frequencies and declaratives longer durations (p < .001). Female frequencies were significantly higher than males' (p < .001), with longer durations observed (p < .001). Particle syllables also showed significantly stronger intensities (p < .001). Finally, we presented melodies converted from these acoustic properties into musical scores based on pitch, duration, and accent. The insights from this analysis of six-syllable Korean sentences will guide further research on developing a system for melodizing large-scale Korean speech data, expected to be crucial in music-based language rehabilitation.

Background and Objectives : Gastric acid reflux has been suggested to have an association with sleep apnea(SA). This study's aim is to evaluate the relationship between reflux laryngitis and SA through the fact that the treatment of reflux laryngitis may impact the snoring and SA related symptoms in selective individuals. Methods : Population consist of 24 males and 10 female aged 34 to 66 years(mean age 50 years) confirmed by Reflux Finding Score(RFS) of PC Belafsky. Thirty four patients with reflux laryngitis and associated symptoms of SA were treated with proton pump inhibitor(Rabeprazole sodium 10mg/day) for 60 days. The degree of snoring and apnea related symptoms were evaluated using questionnaires, and palatine tonsillar hypertropy(PTH) and RFS were compared preoperatively and postoperatively. Results : After antireflux treatment for 60 days, the snoring(p=0.039), daytime sleepiness(p=0.002), and concentration(p=0.011) were significantly improved(p<0.05) and RFS was significantly decreased(p=0.000), but morning headache(p=0.057) and sleep apnea(p=0.083) were not significantly improved(p>0.05) and PTH was not significantly decreased(p=0.328). Conclusion : Treatment of reflux laryngitis significantly impacted the snoring, daytime sleepiness, and concentration in selective individuals. These results suggest some close relationship between reflux laryngitis and SA, and the treatment of reflux laryngitis may be some effective in those with both disorders.

This study was undertaken to analyze the correlation between depression and memory, by considering the occurrence of ApoE ɛ4 and clinical dementia rating in the elderly with Alzheimer's dementia. This study included 50 participants over 65 years of age, evaluated with CDR 0.5 to 2. We performed CDR, SVLT-E, RCFT, SGDS-K, and ApoE genotyping. Spearman's correlation analysis was used for determining the correlation between depression and memory. The results indicate a significant negative correlation between depression and immediate recall verbal memory in the CDR 1 and 2 without ApoE ɛ4 carrier group (p<0.05). Furthermore, a significant negative correlation was also determined between depression and delayed recall verbal memory in the CDR 1 of the same group. Ed. Notes: The previous sentence already shows this correlation. I suggest this should be deleted from this statement. However, no significant correlation was observed between depression and visual memory. This study found a significant correlation between depression and immediate recall verbal memory. Also, the presence of ApoE ɛ4 indicates a significant correlation between depression and delayed verbal recall memory. Taken together, our results indicate that verbal memory training rather than visual memory training can be more effective in early AD. Also, the treatment of depression will provide a complementary effect.

As individual users have to provide more information than the minimum for using information communication service, the invasion of privacy of Individual users is increasing. That is why client/server based personal information security platform technologies are being developed such as P3P, EPAL and XACML. By the way enterprises and organizations using primarily role based access control can not use these technologies. because those technologies apply access control policies to individual subjects. In this paper, we suggest an expression language for privacy enhancing role-based access control policy. Suggested privacy enhancing role-based access control policy language model is a variation of XACML which uses matching method and condition, and separately contains elements of role, purpose, and obligation. We suggest policy language model for permission assignment in this paper, shows not only privacy policy scenario with policy document instance, but also request context and response context for helping understanding.

Purpose : This article was to study mental health status through aggression and stress of children of multicultural families, marriage immigrant and to use them as baseline data. Method : We used questionnaire and collected them from 135 children of multicultural families who live in 2 city and 4 do. Frequency Analysis was used for Demographic Characteristics, t-test and one-way ANOVA for aggression and stress depending on demographic characteristics, and regression analysis for the factors. Result : The first, the total score of aggression of the children of multicultural families was 3.05 and the most high score was verbal aggression, 3.69. Stress was 3.66. The second, there was a significant difference between aggression depending on demographic characteristics and verbal aggression(p=.031) depending on age and anger(p=.011). There was also a significant difference between total aggression(p=.028) depending on economic level and physical aggression(p=.049), verbal aggression(p=.000), anger(p=.036), hostility(p=.042), and stress(p=.011). The third, we analysed the factors affecting aggression of children of multicultural families. There was a significant difference resulting from stepwise regression analysis(F=57.139, p<.001), the results showed a strong explanation of aggression by bad in economic status(p<.01), stress(p<.01), 10 years in age(p<.01), and 13 years in age(p<.01). Conclusion : Aggression depending on demographic characteristics of the children of multicultural families was caused by age, economic level, and stress.

본 연구에서는 해부학 실습 교육과정에 해부설명회를 도입에 따른 의학전문대학원생들의 자기평가요인(만족도, 전공 연계성, 운영 적절성, 의사소통)과 학업성취도와의 상관관계를 분석하였다. 2008-2009학년도 1학기 해부학 실습 교육을 받은 의학전문대학원생들(n=102)이 일부 수업시간을 활용하여 해부설명회에 참가하였고, 보건 의료 계통의 학부생들에게 사체를 활용하여 인체 구조에 대한 설명과 토론을 마친 후 설문지와 소감문을 작성하게 하였다. 이를 바탕으로 자기 평가 요인들을 분석하였고, 2008-2009 학년도 해부학 성적과의 상관관계를 조사하였다. 설문 대상자의 일반적 특성에 따른 자기 평가 요인을 분석한 결과, 성별, 연령, 과거 경험 유무 등의 일반적 특성과 상관없이 만족도, 전공 연계성, 운영 적절성, 언어적 및 비언어적 커뮤니케이션 모두에서 높은 수치를 나타내었다. 자기 평가 요인 중 학업성취도와 높은 상관관계를 갖는 요인은 언어적 커뮤니케이션이었다(p<0.05). 또한 언어적 커뮤니케이션은 비언어적 커뮤니케이션과도 높은 상관관계를 가졌다(r=0.580, p<0.01). 결론적으로 커뮤니케이션 기법을 활용한 해부설명회의 도입은 의전원 학생들에게 심화 학습의 기회를 제공하였고 학습동기를 유발시키며, 적극적인 학습태도를 갖게 하였다. 아울러 커뮤니케이션에 대한 중요성을 깨닫게 되었고, 타 전공자와의 상호교류를 통한 학문적 이해의 폭이 확대되었음을 확인하였다. 본 연구 결과를 바탕으로 진행과정에 나타난 문제점을 보완하고 개선한다면 해부학 실습의 개선 방안으로서 해부설명회의 활용가치가 충분하다고 판단되었다.
