This study sought to explain the process of conflict between early childhood teacher and parent (T-P conflict) and was guided by the following three questions: (a) how does a T-P conflict begin? (b) how does a T-P conflict develop over time? and (c) how does a T-P conflict end? One hundred cases were provided by private kindergarten teachers with experiences of T-P conflict. A qualitative grounded theory design was used for analysis of the data. Open coding and axial coding resulted in six categories: (a) "causes of conflict" (b) "conditional context of conflict" (c) "state of conflict" (d) "amplification of conflict" (e) "problem solving strategies of conflict", and (f) "cease of conflict". The stage of selective coding drew out three core categories: (a) "prelude with tuneless instruments" (b) "duet for discords and concords, and (c) "splendid finale vs. unplanned intermission". Additionally the study raised the doubts about current early childhood education policies based on neo-liberalism and their impacts on relationships between teachers and parents.

The aim of this study was to investigate the conditions and strategies of interaction for the school adjustment for the early entrance students of science academy for the gifted. To know their concerns and process of school adjustment, we interviewed six early entrance gifted students of the science academy and two gifted students preparing for their early entrance with a semi-structured questions. Using the grounded theory, a paradigm model was organized and a core category was abstracted through the open, axial, and selective coding. Based on the open coding analysis, 75 concepts, 21 sub-categories, and 10 categories were derived. In the axial coding, the paradigm model was organized by the link between 10 categories derived from open coding. Through the selective coding, this study discovered the core category about early entrance student's school adjustment was overcoming difficulties by using academic, social, and emotional strategy for school adjustment. Through this, we understand the school adjustment process of the students of early entrance to science academy for the gifted.

Directory searching and index searching methods are two main methods in web search engines. Both of the methods are applied to most of the well-known Internet search engines, which enable users to choose the other method if they are not satisfied with results shown by one method. That is, Index searching tends to come up with too many search results, while directory searching has a difficulty in selecting proper categories, frequently mislead to false ones. In this paper, we propose a novel method in which a category hierarchy is dynamically constructed. To do this, a category is regarded as a fuzzy set which includes keywords. Similarly extensible subcategories of a category can be found using fuzzy relational products. The merit of this method is to enhance the recall rate of directory search by expanding subcategories on the basis of similarity.

The Purpose of this study is to understand phases and paradigms related to voluntary services offered by undergraduates and the processes in which voluntary services are implemented. For this, interviews for 23(men: 10, women: 13) undergraduates were conducted from Aug., 2008 to Apr., 2009 were conducted and the data collected from those interviews were analyzed on the basis of the Grounded Theory. Main analysis procedure is known as codings(open coding, axial coding, selective coding). This analyses produced 119 concepts, 41 subcategories, and 16 categories in open coding. Then, axial coding was conducted to organize the basic framework of generic relationships among psychological motivation, social context, personal perception, practical action, psychological response, and psychological consequence. Core essence is "Volunteer types are categorized simple practice type, self-serving type, and community type." Finally, undergraduate volunteers were explained in 3 types(simple practice, self-serving, and community) on the basis of paradigms. These results were discussed in terms of further research and limitation.

The purpose of this study is to analyze the science lesson plan of pre-service elementary teachers about condensation. Pre-service elementary school teachers in A national university of education was included in this study. Through the analysis of prior research and expert review, a framework for analysis of science lesson plan of pre-service elementary teachers was derived. The results of the using the analysis frame are as follows: First, the ability to apply the instructional model in the science lesson plan about condensation differences in pre-service elementary teachers need to be enhanced due to deviations, and teaching on the exact understanding of condensation-related concepts of pre-service elementary teachers is also needed. Second, there is also a deviation of pre-service elementary teachers in the beginning, development, and finishing composition of lesson course, so feedback should be supplemented. Third, in the sub-domain of lesson environment, there was a demand for specific know-how on the lesson environment. Therefore, support is needed for related PCK growth. Fourth, the sub-domain of lesson evaluation have a variety of perspectives on timing and subjects, and some missing about learning objectives in the composition of evaluation content are found to require complementary teaching. In order to improve this situation, it was found that there was a need to prepare conditions for improving science teaching professionalism of pre-service elementary teachers through in-depth discussions on the teaching methods and organization related to science education in the university of education course.

With the recent emergence of smart tourist cities, premium mobility is being considered an important means of transportation in the tourism. However, there has been insufficient research conducted on the experience of premium mobility among its users. Accordingly, this study used CIT to analyze the components of the user experience of customers who used premium mobility. In order to specifically identify the factors that make up the premium mobility experience, 366 cases of satisfaction and 13 cases of dissatisfaction were collected through a total of 273 online surveys. As a result of the study, based on the customer's experience using premium mobility, CIT was applied to derive 6 categories and 9 sub-factors that constitute the perception of premium mobility. In particular, this study is different from existing studies in that convenience was added as a new category out of the 6 categories, and wide ride comfort and high price were derived as new sub-factors among the 9 sub-factors. Because of this, it has academic significance. Therefore, if scales suitable for quantitative research are developed based on the derived constructs, they could be widely applied to various topics related to premium mobility in the tourism field.

대부분의 한국어 구문 분석은 용언과 명사구 사이의 하위범주화 정보를 이용하여 용언에 대한 명사구의 문법적 역할을 밝히는 방향으로 구문 분석을 시도하였다. 여기에 이용된 용언의 하위 범주화 정보가 단지 자릿수 서술어나 형용사, 자동사, 타동사 등으로 분류하는 수준이었기 때문에 구문 모호성이 많이 발생하고 틀린 문장이 구문적으로 옳기 때문에 옳은 문장으로 인식되는 경우가 발생하였다. 이러한 문제점을 해결하기 위하여 본 논문에서는 한국어의 용언에 따른 문장 형태(문형)를 세분류하고 문장에 필수적으로 나타나는 명사구(NP[case])와 수의적으로 나타나는 명사구(NP[case])를 분류하여 분석을 시도하였다. 확장된 PATR II로 문법을 기술하여 동적인 파싱을 쉽게 제어할 수 있도록 하였다. 문형 정보는 한국어의 기본 구조를 자연스럽게 표현할 수 있기 때문에 그 자체를 기계번역을 위한 한국어 문법으로 설정하는 것이 타당하다고 생각된다.

관절잡음의 발생은 측두하악 관절의 구조적, 기능적 이상의 징후로 여겨져왔다. 이러한 관절잡음을 평가하는데 electrovibratography가 비침습적이고 신뢰할만한 방법으로 제시되어 왔으며 이를 통해 관절잡음의 진동수와 진폭 및 전체 에너지 양상을 숫자화하고 도식화 하는 것이 가능하게 되었다. 기존의 연구에서 여러 가지 관절잡음의 양적, 질적 분석이 시도되어 왔다. 이번 연구의 목적은 관절 잡음이 도식화되어 나타나는 frequency spectrum pattern을 integral>300Hz/<300Hz ratio와 함께 분석하는 것이다. 본 실험에서는 Joint Vibration AnalysisTM를 사용하여 측두하악 관절 장애의 증상이 없는 10명의 대조군과 관절 잡음과 동통이 있으나 개구제한을 보이지 않는 정복성 관절원판 변위의 범주에 있는 20명의 실험군에서 관절진동을 분석하였으며 관절진동 기록 시에 Jaw tracker를 함께 사용하여 개폐구시 관절잡음 발생의 위치를 감별하고 치아접촉음을 배제하여 관절잡음을 분석하였다. 그 후 실험군을 frequency spectrum pattern에 따라 4가지 하위 그룹으로 나누어 분석하였다. 실험 결과 실험군과 대조군의 하위 그룹 1에서 유사한 frequency spectrum pattern과 ratio범위를 보였으며 실험군의 하위 그룹 2,3,4 에서는 더 불규칙한 에너지 양상을 보이는 frequency spectrum pattern과 더 큰 ratio가 관찰 되었다. 이번 연구를 통해 Joint Vibration AnalysisTM가 악관절 진동의 특성을 감별하는데 유용함을 알 수 있었고 Joint Vibration AnalysisTM를 이용한 지속적인 진동 분석이 환자 교육뿐 아니라 성공적인 턱관절 기능이상의 진단과 치료에 유용할 것으로 사료된다.

한국어의 의미 분석을 위해서 의미소가 부여된 말뭉치(Sense-Tagged Corpus)의 구축은 필수적이다. 의미 태깅은 어휘의 다의적 특성으로 인해, 형태소나 구문 태깅에서와 같은 규칙 기반의 처리가 어려웠다. 기존의 연구에서 어휘의 의미는 형태소와 구문적 제약 등의 표층상에서 파악되어 왔으며, 이는 의미 데이터 기반으로 이루어진 것이 아니었기에, 실용적인 결과를 얻기가 힘들었다. 본 연구는 한국어의 구문과 의미적 특성을 고려하고, 용언과 모어 성분간의 의존 관계 및 의미 정보를 나타내는 하위범주화사전과 어휘의 계층적 의미 관계를 나타낸 의미사전(시소러스)을 이용하여, 반자동적인 방법으로 의미소가 부여된 말뭉치의 구축을 위한 기준과 알고리즘을 논하고자 한다.
