Lead Borate 유리內에서의 Fe ion의 Mossbauer 效果硏究

姜信珪,金在慶 嶺南大學校附設 基礎科學硏究所 1984 基礎科學硏究 Vol.4 No.-

A Mossbauer spectroscopic study has been mad on χFe₂O₃ㆍ1-χ(PbOㆍ3B₂O₃), where 10≤χ≤50mole%. The characteristic feature of all the spectra is the appearance of three peaks, due to two pairs of peaks of gradrupole doublet of ?? and ??. The mean values of isomer shift and guadrupole splitting for the ferric cations are 0.19mm/sec and 1.10mm/sec, and for ferrous cations 0.77mm/sec and 2.70mm/sec. The isomer shift and quadrupole splitting of the ferrous and ferric peaks in the Mossbauer spectra are almost independent of the Fe₂O₃content. The line width of the quadrupole split peaks of ?? increases with decreasing iron content of the glass, and that of the ?? increases too in the same manner. The ratio of ferrous to ferric cations increases with decreasing the content of Fe₂O₃. The possible explanation for all the features mentioned above are presented.

피드백을 이용한 문제은행 시스템의 설계 및 구현

강신재,김정미 대구대학교 2005 대구대학교 학술논문집 Vol.1 No.1

현재 웹상에는 많은 온라인 문제은행이 있고 또 생겨나고 있다. 이러한 문제은행들은 회원이나 학습자의 실력향샹을 도모하기 위하여 피드백을 사용한다. 그러나 아직 피드백의 연구가 활발히 이루어지지 않고 있어 그 가치를 십분 이용하지 못하고 단순히 반복 학습의 형태로만 사용되어지고 있다. 이에 본 논문에서는 피드백의 효용가치를 재고찰하고 이를 발전시켜 기존 문제 은행시스템의 진보를 꾀하고자 한다. 따라서 본 논문에서는 기존 피드백보다 좀 더 진보된 형태의 피드백 시스템의 형태로 세분화된 피드백을 제안하였다. 개인피드백과 전체피드백으로 세분화 하고 단순 반복의 학습형태를 탈피하여 문제 출제시 피드백의 일정부분을 재출제하는 형태로 그 방향을 제시하고 있다. 그리고 이 시스템이 기존 시스템보다 효율적인 것을 규명하였다. There are many on-line problem banks on the web and they are still be created. These problem banks put 'feedback' to practical use. However, we simply use 'feedback' to repeat studying without applying its whole value because the research on 'feedback' can't be accomplished vigorously. Then, the paper shall make an attempt to re-consider utility and value of 'feedback', and progress the existing system of problem banks. Therefore, the paper proposed a much advanced, detailed 'feedback' system than the existing one. The paper proposed an advanced direction of feedback system which is progressed by forms of representing some problems returning from first feedback. Proposed system is segmented into personal-feedback and whole-feedback, and is broken from simple repeating study form.

한국어 의미 분석을 위한 구문 관계에서 의미 관계로의 규칙 기반 사상 기법

강신재,박정혜 대구대학교 정보통신연구소 2003 情報通信硏究 Vol.1 No.2

본 논문은 한국어정보처리 과정에서 구문 관계를 의미역으로 사상시키기 위한 규칙을 효과적으로 구축하는 방법을 제시하고 있다. 의미역의 결정은 의미 분석의 핵심 작업 중 하나이며 자연어처리에서 해결해야 하는 매우 중요한 문제 중 하나이다. 일반적인 언어학 지식과 경험만 가지고 의미역 결정 규칙을 기술하는 것은 작업자의 주관에 따라 결과가 많이 달라질 수 있으며, 또 미처 생각지 못한 부분들도 있을 수 있기 때문에 규칙의 적용률이 많이 떨어질 수 있다. 하지만 본 논문에서 제시하는 방법은 대량의 원시 말뭉치를 분석하여 실제언어의 다양한 사용례를 반영하며, 또 다수의 인어학자들이 심도 있게 구축하고 있는 세종전자사전의 격틀 정보도 함께 고려하기 때문에 보다 객관적이고 효율적인 방법이라 할 수 있다. 의미역을 보다 정확하게 결정하기 위해 구문관계, 의미부류, 형태소 정보, 이중주어의 위치정보 등의 자질 정보를 사용하였으며. 특히 의미부류의 사용으로 인해 규칙의 적용률이 향상되는 효과를 가져올 수 있었다. This paper presents an efficient construction method of determination rules of thematic roles from syntactic relations in Korean language processing. This process is one of the main core of semantic analysis and an important issue to be solved in natural language processing. It is problematic to describe rules for determining thematic roles by only using general linguistic knowledge and experience, since the final result may be different according to the subjective views of researchers, and it is impossible to construct rules to cover all cases. However, our method is objective and efficient by considering large corpora and case frames in the Sejong Electronic Lexicon of Korean. To determine thematic roles more correctly, our system uses syntactic relations, semantic classes, morpheme information, position of double subject. Especially by using semantic classes, we can increase the applicability of the rules.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The purpose of this study was to analyze the teaching perspectives of beginning physical education teachers. Therefore, the following was investigated: (a) a composite biography of beginning teachers, (b) the construction of beginning teachers' teaching perspectives, and (c) the changes in beginning teachers' teaching perspectives. The investigator employed three established data-gathering methods: interviews (patton, 1990), observation(Spradley, 1980), and document analysis (Goodman, 1985: Tabachnick et al, 1980). Interviews (Patton, 1990) were the primary data-gathering method. The principles of the "constant comparative" method of analysis (Glaser & Strauss, 1967) were used to analyze data obtained from observations, interviews and document analysis. The findings of this study indicated that the beginning teachers were affected in different ways by the apprenticeship of observation, but they were all profoundly affectted by it. While many beginning teachers in this study tried to pattern themselves after good teachers, some beginning teachers rejected the negative characteristics of some of their former teachers, particularly those who were authoritarian. At least some teachers tried to critically reflect on their apprenticeship: the poor experiences they encountered as students prompted them to create teaching environments different from those they personally experienced. The socializing power of the university appeared to be weak compared with the apprenticeship of observation and the contending norms of schools. Furthermore, this study supports the contention that formal teacher education program is limited in its ability to reshape previously established beliefs and practices. Many changes took place in the beginning teachers' perspectives and practices. First of all, many believed they became more effective in their teaching methods and in controlling students. Secondly, with their growing confidence, the beginning teachers with well-established teaching perspectives attempted to express their teaching perspectives whenever they perceived it as appropriate while beginning physical education teachers with less-established teaching perspectives were easily molded into the framework of the status quo. The third, most prevalent change detected was related to their conceptions of student control. Six out of thirteen beginning teachers experienced the reality shock (Veenman, 1984) common among first year classroom teachers. The deginning teachers' feelings of unpreparedness and related reality shock might be traced to the grueling situations found in the Korean educational system, and unrealistic university preparation program in Korea, and the superficial attitudes they had about their university coursework. Recommendations of teacher educators and researchers of teacher socialization were made to improve the quality of preparation programs. Recommendations were also made for beginning teachers to help them move from novice teachers to successful veterans.

키워드의 유사도를 이용한 문제은행 시스템의 설계 및 구현

배미영,강신재 대구대학교 2006 대구대학교 학술논문집 Vol.1 No.2

학습의 성취도를 보다 효과적으로 높이기 위해서는 학습자에게 학습의 결과에 따라 피드백 되어지는 문제의 신뢰성과 타당성을 높여 정확하게 피드백을 시킬 수 있는 시스템이 필요하다. 따라서 본 논문에서는 기존 문제은행 시스템 대부분이 가지는 학습 평가 후 피드백 시 출제되는 문제의 신뢰성이 떨어지는 문제를 해결하기 위하여 문항의 유사도에 기초하여 신뢰성 있고 타당성 있는 유사 추천 문항을 피드백하여 학습자의 이해도를 높일 수 있도록 하는 키워드의 유사도를 이용한 문제은행 시스템을 설계 및 구현하였다. 키워드의 유사도를 이용하여 정확하게 보완하는 학습을 하도록 함으로써 피드백의 활용도를 높여 교육적 효과가 증진되도록 하였으며 실제 성능평가를 통하여 본 연구에 사용된 문제은행 시스템에서 학습한 학습자들의 학업 성취도가 기존 문제은행 시스템을 이용한 학습자보다 높아진 것을 확인하였다. To effectively increase the degree of accomplishment in study, a system that can accurately feedback by increasing reliance and suitability of problems that feedback according to the result of studies to learners is needed. Therefore, to solve the impaired reliance of provided questions when feeding back after the study evaluation which the most existing item pools have, this paper designs and implements an item pool system based on a similarity of keywords that can increase the understanding of learners by feeding back reliable and suitable similar recommended items on the basis of items' similarity to complement insufficient parts of learners. By allowing learners to study that accurately complements using a similarity of keywords, we attempted to increase the educative effects by increasing the practical use of feedbacks in the education. Moreover, we could verify the accomplishment degree of learners whom studied in the item pool system used in this study has increased more than whom used the existing item pool system through the actual efficiency evaluation.

Collaborative Spam Mail Filtering between Desktop Machine and PDA

김종완,강신재 대구대학교 정보통신연구소 2009 情報通信硏究 Vol.6 No.1

Currently most spam filters work on desktop environment such as client PC and server station. However an anti-spam service is also needed in personal devices including PDA and cellular phone in the ubiquitous age. Thus we will present a text based spam filtering approach cooperates involving with a PC and a PDA. We have classified text information in a mail into two kinds of information that can identify spam mails among all messages including non-spam or legitimate mails. The definite information is the mail sender’s information, URL, a certain spam keyword list, and the less definite information is the word list extracted from the mail body. We first classified the spam mail by using the definite information, and then used the less definite information contained in the email body for SVM learning in the next phase. According to the experimental results in this work, a PC and PDA collaborating spam filter showed the same performance as the standard desktop filter.
