The purpose of this research is to investigate the difference across children's grades in the ambiguous idiom comprehension, the relation with the ambiguous idiom comprehension and language, perspective-taking ability, and what the factors which can influence to comprehend the ambiguous idioms is. 70 elementary school students from 1st grade to 6th grade participated in this study. They were classified with 3 groups, A(1st-2nd grade), B(3rd-4th), C(5th-6th) group and tested in the ambiguous idiom comprehension, receptive vocabulary, problem-solving and perspective-taking. Results of this study are followed. First, there was a significant difference in three groups in the ambiguous idiom comprehension task. And there was significant difference between A group and B, C but not between B and C. Second, in relation with the ambiguous idiom and language ability, perspective-taking ability, there was positive relation with the ambiguous idiom comprehension and them. Finally, the factors which can influence to comprehend the ambiguous idioms is the receptive vocabulary ability, cue-assumption and resolution-inference ability in problem-solving. And the 3 factors explain 65.3% of ambiguous idiom comprehension ability.

The aim of this study is to investigate the prosodic aspects of ambiguous sentences in Korean produced by Chinese Korean Learners (L1: Chinese, L2: Korean). In Korean, sentence ambiguity can be caused by homonym or syntactically ambiguous structure. In spoken language however all ambiguity can be resolved by different prosodic features according to the meaning that they transmit. In this study we examined whether Chinese Korean Leaners also distinguish, in production, ambiguous sentences on the basis of prosodic characteristics. For this study 4 Korean natives speakers and 10 advanced Chinese Korean learners participated in the production test. The material analysed constituted 10 Korean sentences in which 6 sentences are lexically ambiguous and 4 sentences contain structural ambiguity. The results show that Korean native speakers produced ambiguous sentences by different prosodic structure depending on their semantic and syntactic structure. Chinese speakers also show distinct prosodic structure for different ambiguous sentences in most cases. But in the phonetic realization, the internal pitch range was greater for Korean native speakers than Chinese learners.

The aim of this study is to investigate the prosodic aspects of structural ambiguous sentences in Korean produced by Japanese Korean learners and the influence of their first language prosody. Previous studies reported that structural ambiguous sentences in Korean are different especially in prosodic phrasing. So we examined whether Japanese Korean leaners can also distinguish, in production, between two types of structural ambiguous sentences on the basis of prosodic features. For this purpose 4 Korean native speakers and 8 Japanese Korean learners participated in the production test. Analysis materials are 6 sentences where a relative clause modify either NP1 or NP1+NP2. The results show that Korean native speakers produced ambiguous sentences by different prosodic structure depending on their semantic and syntactic structure (left branching or right branching sentence). Japanese speakers also show distinct prosodic structure for two types of ambiguous sentences in most cases, but they have more errors in producing left branching sentences than right branching sentences. In addition to that, interference of Japanese pitch accent in the production of Korean ambiguous sentences was observed.

잠재의미분석은 단어 의미를 동일한 맥락 (문장/문서) 하에서 동시에 제시되는 단어들의 공기성(co-occurence)으로 정의한다. 이 분석에서 한 단어는 맥락들을 대표하는 측들로 구성된 다차원 상의 한 점으로 표상 되며, 단어 의미는 각 단어가 맥락 속에서 등장한 빈도로 정의된다. 이 다차원 의미공간은 SVD를 통하여 차원이 축소되어 추상된 의미를 표상 한다. 이 연구는 다의어의 표상이 가능하도록 LSA를 발전시켰다. 제안된 LSA는 축에 대한 해석이 가능하도록 축의 회전을 도입하였으며 다의어 표상을 가능하게 하였다. 시뮬레이션에서는, 먼저 LSA에 의해 산출된 단어-맥락 빈도표에서 다의어를 포함하고 있는 문서들만을 재 수집한 다음 문서들을 다의어 의미별로 분류하였다. 두 번째 단계에서는 다의어의 특정의미에 대한 표상을 분류된 단어-맥락 빈도표에서 비해당 의미에 대한 맥락들을 제거한 후 LSA를 적용하여 구성하였다. 시뮬레이션 결과는 다의어의 의미들을 LSA가 표상 할 수 있음을 보여주었다. 이는 축회전을 포함한 LSA가 다의어 다중의미를 표상 할 수 있고 실용적인 측면에서 웹검색 엔진에도 적용될 수 있음을 시사한다.

The purpose of this study is to identify the factors that influence stress experienced by nursing students and to provide a perceived causal structure model among these variables. The ultimate goal of this study is to develop efficient guidance to clinical nursing education in this population. This study intends to apply perceived causal structure: network analysis method which was developed by Kelly(1983), and has been applied in nursing research. This method is selected to show dynamic relationship of stressor using network method. Data was collected from convenient sample of 186 junior college nursing students who had the clinical practice experience during 10 weeks. Data collection and analysis was conducted in 2 steps from December, 9, 2002 to February, 8, 2003. Step 1.: Data was collected using literature review(10 articles) to identify the causes of stress. Nine causes of stress were extracted. Step 2.: As perceived casual structure network study, data was collected using questionnaires which included 9 extracted cause and stress. The questionnaire contained a 10 X 10 grid table with 10 causes and effects printed. In network analysis, 'Yes' was scored as 1, 'No' was scored as 0, and the mean(maximum 1, minimum 0) was calculated. Construction of the network under inductive eliminative analysis which stopped the construction of the network when the consensual agreement level dropped near 50% was proceeded by adding causes in order of the mean rating level. In this study, construction of the final network was stopped by consensual agreement level of 52% of the total subjects. The results are summarized as follows : Step 1: Investigation of the causes of stress ; The extracted causes of stress from quality data was identified 9 categories ; negative nurse, lack of clinical practice opportunity, ambiguous role, negative patient, lack of nursing knowledge and skill, difficult of personal relations, inefficient clinical practice guidance, gap of theory and practice, lack of support. Step 2 : Construction of the perceived causal structure model ; 1) The most central cause of stress is ambiguous role in the systems of causation. 2) The distal cause of stress is inefficient clinical practice guidance 3) The causes that have a number of outgoing link are negative nurse, ambiguous role. 4) The causes that have a number of incoming link are ambiguous role, gap of theory- practice, lack of clinical practice opportunity, lack of nursing knowledge- skill. 5) There is a mutual relationship between stress and difficult of personal relations, stress and ambiguous role, ambiguous role and negative nurse, ambiguous role and lack of clinical practice opportunity, ambiguous role and lack of nursing knowledge-skill, lack of nursing knowledge-skill and gap of theory- practice. In conclusion, the network suggests that the first centre cause is related on ambiguous role and the second on negative nurse, inefficient clinical practice guidance in the systems of causation

The purpose of this study is to investigate difficulties in using prosodic information to identify the meaning of ambiguous sentences in children with high functioning autism (HFA). Fifteen high functioning autistic children and fifteen children who matched their chronological age (CA) participated in this study. We compared the performance of the two groups by conducting syntactically and affectively ambiguous sentence comprehension (SASC and AASC) tasks. The results of this study show that in both tasks, the difference between the two groups was statistically significant at each condition and the performance of high functioning autistic children was significantly lower. In a correlation analysis of major variables, children who matched CA showed a correlation between prosody-only (PO) and AASC, while children with HFA showed a correlation between PO and MO (morpheme-only). Children with HFA used grammatical morpheme information to understand general sentences. We found that the ability to use prosodic information in children with HFA is significantly lower than that of normally developed children. Considering the relevance of prosody to linguistic, non-linguistic and emotional aspects of communication, improving prosodic perception is thought to be a way to mediate deficits in the comprehension of ambiguous sentences in children with HFA.

The purpose of this study is to investigate fashion advertisements portraying ambiguous sex phenomena, including homosexuality codes and to analyze the meaning of these advertisements in order to develop effective fashion advertisements strategies. The method of this study was to observe the readings about ambiguous sex theory, including homosexuality, and analyze fashion advertisements that express this through the Internet and fashion journals. The ambiguous sex expression seen in fashion advertisements meet various consumers' needs which is what the latest advertisement market requires, and offer competitive brand image by fresh appeal. In the background, there are various complex factors like the change of contemporary spirit, and designers' tastes and values about homosexuality. The kinds of ambiguous sex expression techniques portrayed in fashion advertisements can be divided as the ambiguity of physical codes and the ambiguity of sex role identity. These advertisements do play a role as a public campaign for a change in society from the sociocultural point of view. And, from the economical viewpoint, they approach the consumer as a fresh marketing strategy. From the esthetic viewpoint, they express new esthetic sense named “edge” And seen from the designers' viewpoints, they express designers' private sexual identities.

This study is for seismic analysis of building structures with ambiguous modal direction This case is revealed symmetrical building structure or the structure that isn't coincided building axis with physical axis. Seismic analysis-time history analysis, response spectrum analysis and lateral force procedure-is carried out. It is concluded that analysis method for the structure with ambiguous modal direction don't suitable for lateral force procedure. It is recommended to use the CQC method for combining modal responses to the individual components and the SRSS rule for combining responses to the two horizontal components are of nearly equal intensities.

According to the previous work, various well known methods including maximum a posteriori probability classifier (MAP) and multi layer perceptron networks classifier (MLP) showed competitive results. Since even the small errors often leads to a fatal result, we investigated the method that reduces classification error perfectly by screening out some ambiguous patterns. Those ambiguous patterns can be examined by routine biopsy. We incorporated an ambiguous category in MAP and MLP. Classification results involving 216 spectra gave 100% sensitivity for the case of MLP.

본 논문에서는 한국어 문서의 분류 정밀도 향상을 위해 애매어와 해소어 정보를 이용한 확장된 벡터 공간 모델을 제안하였다. 벡터 공간 모델에 사용된 벡터는 같은 정도의 가중치를 갖는 축이 하나 더 존재하지만, 기존의 방법은 그 축에 아무런 처리가 이루어지지 않았기 때문에 벡터끼리의 비교를 할 때 문제가 발생한다. 같은 가중치를 갖는 축이 되는 단어를 애매어라 정의하고, 단어와 분야 사이의 상호정보량을 계산하여 애매어를 결정하였다. 애매어에 의해 애매성을 해소하는 단어를 해소어라 정의하고, 애매어와 동일한 문서에서 출현하는 단어 중에서 상호정보량을 계산하여 해소어의 세기를 결정하였다. 본 논문에서는 애매어와 해소어를 이용하여 벡터의 차원을 확장하여 문서 분류의 정밀도를 향상시키는 방법을 제안하였다.
