The ethical problems related to climate changes have basically different character from the ethical problems which we have experienced until now. In order to approach ethical problems of climate changes for forseeing, mitigating and adapting many complicated situations which result from climate changes we should breake away from the point of anthropocentrism at first. Secondly, the education of the ethics of climate changes is very important in all levels of schools. It is very important and urgent to decide what and how we should teach. Finally, the sustainability has important role in the justification of why and what we should take actions against climate changes.

This study investigates what older adults give meaning of ageism with relation to their self-identity. The main findings are as follows. The participants' response to daily life ageism is divided in four types: 'denial', 'evasion', 'acceptance', 'problematic proposal', and 'isolation'. In conclusion, this study contributes to understanding ageism in-depth. The findings of this study discover tension and suppression within society regarding ageism from the perspectives of the older participants, and reveal the latent dimension which is not caught with the language.

This study examined pre-service teachers' pedagogical content knowledge of fraction division in a context where they were asked to write a story problem for a symbolic expression illustrating a whole number divided by a proper fraction. Problem-posing is an important instructional strategy with the potential to create meaningful contexts for learning mathematical concepts, especially when real-world applications are intended. In this study, story problems written by 135 elementary pre-service teachers were analyzed with respect to mathematical correctness. error types, and division models. Patterns and tendencies in elementary pre-service teachers' knowledge of fraction division were identified. Implicaitons for teaching and teacher education are discussed.

This study questions that mathematical evaluations strive to memorize fragmentary knowledge and have an objective test. To solve these problems on mathematical education We did descriptive test. Through the descriptive test, students think and express their ideas freely using mathematical terms. We want to know if that procedure is correct or not, and, if they understand what was being presented. We studied this because We want to analyze where and what kinds of faults they committed, and be able to correct an error so as to establish a correct mathematical concept. The result from this study can be summarized as the following; First, the mistakes students make when solving the descriptive tests can be divided into six things: error of question understanding, error of concept principle, error of data using, error of solving procedure, error of recording procedure, and solving procedure omissions. Second, students had difficulty with the part of the descriptive test that used logical thinking defined by mathematical terms. Third, errors pattern varied as did students' ability level. For high level students, there were a lot of cases of the solving procedure being correct, but simple calculations were not correct. There were also some mistakes due to some students' lack of concept understanding. For middle level students, they couldn't understand questions well, and they analyzed questions arbitrarily. They also have a tendency to solve questions using a wrong strategy with data that only they can understand. Low level students generally had difficulty understanding questions. Even when they understood questions, they couldn't derive the answers because they have a shortage of related knowledge as well as low enthusiasm on the subject.

1999년 제1회 형태소 분석기 및 품사태거 평가 워크숍 이후 표준안에 대한 새로운 대안이나 문제제기등을 제시한 논문은 전무하다. 본 연구에서는 평가대회 참가 이후 표준안을 수정한 새로운 유형의 형태소 분석 프로그램을 제작하여 그 실용성과 앞으로의 발전 가능성과 문제점을 밝혀, 계층구조형의 형태소분석 시스템을 채택하고 있는 일본의 JUMAN을 참조 새로운 유형의 형태소 분석형식을 제시한다. 본 연구는 일본방송협회 방송기술연구소(이하 NHK기술 연구소)의 의뢰에 인한 것이며 어절단위의 표준안과 다른 형태소 단위를 기본요소로 삼고 있으며 활용형을 갖고 있는 용언에 대해서는 활용형의 전개를 하고 있다. 어절단위로 탈피한 이유는 형태소 분석의 기본요소로써 어절단위 보다는 형태소 단위를 기준으로 삼는 것이 생산성이 높다고 생각된다. 어절정보와 문장정보는 XML(extensible makrup language)등의 별도의 정보를 주는 방법을 채택했다. 음절말음이 자음인지 모음인지의 음운 정보에 따라 활용형을 차별했으며 표준안과 달리 명사의 종류와 개념을 세분화했다. 아울러 조사와 어미등의 검색어와 함께 음절을 형성하고 있는 비검색어 대상은 배제하는 프로그램과 표준안의 어절방식으로 출력하는 3가지 프로그램을 작성했다. 본 연구에서는 계층구조의 형태소분석 프로그램의 가능성과 한국어의 특성을 고려한 출력항목등을 고찰하는 것을 목적으로 한다.

This research aims to propose a reference for prevention and education of medical dispute in dental clinic and to recognize anew about medical malpractice, by analyzing medical dispute. The results from data were based on questionnaires and replies about medical complaint, which were received the Busan Dental Association from November, 2000 to June, 2007, were as follows; 1. It were categorized 35 cases to 51 detail patterns. These cases were consists of complicated problem. 2. The cases, which were related to the treatment for prosthesis and orthodontics, became an issue. 3. In the case, which was related to the treatment for prosthesis and orthodontics, there were complaints in order of symptoms(occlusal discomfort, hypersensitivity, abnormal pain) and aesthetics after equipped prosthesis, and so on. 4. There was a tendency toward increasing complaints along with an increase of treatments (except conventional ways) for implant and so on.

This study was researched by practical method in a subjectivity study accessible in-depth, in sloughing off old habit of functional quantity analysis about acceptance effect of health public advertising. The perception pattern come out in this study were divided into three types in Q-methodology. The result is as follows ; it is that divided '1[(N=9) : Profit & truth type], 2[(N=9) : Profit & Sympathy type], 3[(N=7) : Profit & Prevent education type] '. Like this, it found that is very different type all over. Hereafter, this study is to ascertain acceptance behavior about reception type on acceptance effect of health public advertising ; to offer a developmental suggestion about it.

작업과 관련된 근골격계 질환은 선진국에서는 1970년대부터 문제가 제기되어 왔다. 특히 좋지 않은 작업자세, 손가락의 반복사용에 의한 목, 어깨, 손목 등의 누적된 근골격계 질환이 문제가 되고 있다. 우리나라에서도 작업과 관련된 근골격계 질환에 연구가 최근에 많이 진행되고 있으나 주로 외국의 연구이론을 적용하고 있으며 국내의 기초 데이터는 매우 부족한 형편이다. 본 연구는 근골격계 질환을 유발시키는 작업유형 가운데 유발율이 상대적으로 높은 국내 H 회사의 맨홀작업의 근골격계 질환의 실태를 알아내고 이를 유발시키는 여러 인자를 찾아내었다. 또한 신체의 아픈 부위와 정도에 따른 작업내용과 작업환경 조건과의 관계도 규명하였다. 이러한 연구 자료는 효과적인 예방 프로그램을 계획하고 실행하는 데 많은 도움을 줄 수 있을 것이다.

This study was researched by practical method in a subjectivity study accessible in-depth, in sloughing off old habit of functional quantity analysis about food preference of an expressway resting place customer. The perception pattern come out in this study were divided into four types in Q-methodology. The result is as follows ; it is that divided '1[(N=7) : Cleanliness-selection Type], 2[(N=13) : Economy Type], 3[(N=9) : Selling-area Goodwill Type], 4[(N=10) : Self-satisfaction Type]'. Like this, it found that is very different type all over. Hereafter, this study is to ascertain acceptance behavior about reception type on food-preference of an expressway-resting-place-customer ; to offer a developmental suggestion about it.
