This study is to explain understanding types about the concept of a 'Region' in the 3rd grade high school students(39) through open-ended questionnaires and describe the pedagogical utilizations for this. Students' understanding types about the concept of a 'Region' are compared and then determined through two meaning agreement and association between meaning of students' understanding which is collected through open-ended questionnaires and meaning of a 'Region' which is described in high school curriculum. The results are as in the following. First, Students' understanding types about the concept of a 'Region' were divided into four categories: full, partial, ambiguous, and converted understanding. Second, The degree of right meaning agreement and association existing between two meanings is rising steadily by converted, ambiguous, partial, and full understanding. For this reason, This result can make sure the understanding degree about the concept of a 'Region' is different depending on the students. Third, Students' partial understanding, ambiguous understanding and converted understanding on region concept could be judged as misconception not fully corresponded to region concept in the curriculum explanation. Fourth, Teachers can achieve conceptual change through this misconception as a subject matter of educational dialogue for meaning change.

The present study was to investigate the developmental change of adolescent's theory of mind. In addition, the relations between theory of mind and the social competence were investigated. Sixty students in each the 6th and 8th grade group were participated in this study. Adolescents' understanding of mind were measured by four kinds of mindreading tasks; the second-order false belief tasks, understanding the ambiguous social behaviors tasks, understading the hidden meaning of a figurative statement tasks, and the "faux pas" tasks. Social skills were measured by social skill scales. Eighth graders performed better than the 6th graders on the understanding the ambiguous social behaviors tasks and faux pas tasks but not on the second-order false belief tasks and understanding the hidden meaning of figurative statement tasks. The results suggests that the mindreading ability continues to develop during the adolescence, especially the ability to interpret others' ambiguous social behaviors by reading their mental states and the ability to understand that a person says a faux pas it is due to a mistaken belief. In addition, the understanding the ambiguous social behaviors tasks was found to be the best task to predict social behaviors. The results suggests that the mindreading ability would be a significant explanatory factor on social competence.

In recent offshore industries, various ambiguous terms have been used without clear definition or classification, causing difficulties in legal, technical, and educational understanding and usage. For an example, the commonly used term of 'Offshore Plant' in Korea is not an universal word technically. There has been no clear technical or legal definition about the 'Offshore Plant' and its classification is also very ambiguous; sometimes it is used to refer offshore oil and gas production platform or it is used to mean offshore renewable power generation plant in some cases. To build a conceptual framework, therefore, this paper suggests a classification of offshore units (1) using internationally agreed terms, (2) agreed with the technical classification used by the ship classification society and (3) being able to include not only the current but also future concepts of offshore units.

Comprehension monitoring is a process of message evaluation and a very important skill of communication. Comprehension monitoring is a necessary language skill in classroom, as it is important for children to assess their own understanding of task instructions and teaching content. The present study investigated comprehension monitoring skill of children with Specific Language Impairment(SLI) compared to age-matched children and language-matched children. 18 vignettes and 6 displays were constructed. Children were asked to choose one object or 'DK' card from a display after the children listened to the vignettes. The results showed that children with SLI didn't have problem in comprehending unambiguous utterance and using prior statement. However, they had problem in monitoring comprehending ambiguous utterance compared age-matched children. Their performance were similar to language matched younger children. With respect to their performance, several possible explanations were discussed.

CMP (Chemical-Mechanical Polishing) is a process in which both chemical and mechanical mechanisms act simultaneously to produce the planarized wafer. CMP process is an extensive usage and continuing high growth rates in the semiconductor industry. The understanding of the process, however, is much slower. The nature of material removal from the wafer is still undefined and ambiguous. Material removal rate according to the slurry flow rate is also undefined and ambiguous. Thus, in this study, the basic mechanism of material removal rate as slurry flow rate is defined in terms of energy supply and energy loss.

In this study, university students were provided with repeated opportunities to represent their ideas graphically, and to examined via their drawings the extent to which they could visualize macroscopic phenomena microscopically. These drawings provided insight into the students' basic understanding of solution chemistry, revealing three conceptual models: the Undifferentiated Symbolic Model, the Particulate Model, and the Symbolic Ionic Model. Generally speaking, students who had poor conceptual understanding tended to exhibit the Undifferentiated Symbolic Model, whereas students with deeper understanding tended to employ the Symbolic Ionic Model. Students' conceptual comprehension was predictable from their graphical representations, which better elucidated what they actually comprehended about the phenomena, as opposed to their ambiguous verbal descriptions alone. The results of this study demonstrated a lack of development in university students' conceptions of solutions. Their weakness in understanding at the molecular-level became more obvious when they were asked to represent their ideas in drawings. Few students exhibited expert knowledge, and several common misconceptions were found, which indicated typical difficulties students have perceiving common phenomena at the molecular level. The findings of this study illustrate how eliciting graphical representations can be used to assess students' conceptual understandings.

There has been an increasing necessity of Semantic Web-based metadata that helps computers efficiently understand and manage an information increased with the growth of Internet. However, it seems inevitable to face some semantically ambiguous information when metadata is generated. Therefore, we need a solution to this problem. This paper proposes a new method for automated metadata generation with the help of a concept of class, in which some ambiguous words imbedded in information such as documents are semantically more related to others, by using probability model of consequent words. We considers ambiguities among defined concepts in ontology and uses the Hidden Markov Model to be aware of part of a named entity. First of all, we constrict a Markov Models a better understanding of the named entity of each class defined in ontology. Next, we generate the appropriate context from a text to understand the meaning of a semantically ambiguous word and solve the problem of ambiguities during generating metadata by searching the optimized the Markov Model corresponding to the sequence of words included in the context. We experiment with seven semantically ambiguous words that are extracted from computer science thesis. The experimental result demonstrates successful performance, the accuracy improved by about 18%, compared with SemTag, which has been known as an effective application for assigning a specific meaning to an ambiguous word based on its context.

Most functional programming languages allows programmers to write ambiguous rules, under the strategy that pattern-matching will be performed in a direction of 'from top to bottom' way. While providing programmers with convenience and intuitive understanding of defining default rules, such ambiguous rules may make the semantics of functional languages unclear. More specifically, it may fail to apply the equational reasoning, one of most significant advantage of functional programming, and may cause to obscure finding a formal way of translating functional languages into the ${\lambda}$-calculus; as a result, we only get an ad hoc translation. In this paper, we associate with separability of term rewriting systems, holding purely-declarative property, pattern-matching semantics of lazy functional languages. Separability can serve a formalism for translating lazy functional languages into the ${\lambda}$-calculus.

Objective: The aim of this study was to achieve a qualitative understanding of childcare teachers' cooperation experiences with Nuri curriculum teaching assistants. Methods: The study adopted a qualitative research design. Participants comprised 23 childcare teachers working with Nuri curriculum teaching assistants. Focus group interviews were conducted to discuss their cooperation experience with the teaching assistants. Qualitative themes analyses were carried out following individual-level analyses, group-level analyses, and cross-group-comparisons. Results and Conclusion: The results showed that childcare teachers, at first, had low expectation for Nuri curriculum teaching assistants because they have ambiguous job descriptions. However, the teachers' actual interactions exhibited cooperation effects on improving the quality of childcare. Childcare teachers suggested the ways to promote cooperation between childcare teachers and Nuri curriculum teaching assistants at individual and systemic levels.
