  • 고성능의 질의응답 시스템을 구현하기 위해서는 사용자의 질의 의도를 파악할 수 있는 질의 유형 분류기가 필요하다. 본 논문에서는 지지 벡터 기계(support vector machine, SVM)를 이용한 질의유형 분류기를 제안한다. 본 논문에서 제안하는 질의 유형 분류기의 분류 과정은 다음과 같다. 우선, 사용자 질의에 포함된 어휘, 품사, 의미표지와 같은 다양한 정보를 이용하여 사용자 질의로부터 자질들을 추출한다. 다량의 자질들 중에서 유용한 것들만을 선택하기 위해서 카이 제곱 통계량을 이용한다. 추출된 자질들은 벡터 공간 모델로 표현되고, 문서 범주화 기법 중 하나인 지지 벡터 기계는 이 정보들을 이용하여 질의 유형을 분류한다. 본 논문에서 제안하는 시스템은 질의 유형 분류 문제에 자동 문서 범주화 기법을 도입하여 86.4%의 높은 분류 정확도를 보였다. 또한 질의 유형 분류기를 통계적 방법으로 구축함으로써 lexico-syntactic 패턴과 같은 규칙을 기술하는 수작업을 배제할 수 있으며, 응용 영역의 변화에 대해서도 안정적인 처리와 빠른 이식성을 보장한다.

  • WBI(Web Based Instruction)는 웹을 매체로 활용하여 원거리에 있는 학습자를 교육시키는 형태로서 교수자와 학습자간 상호작용을 가능하게 하고, 다양한 형태의 학습자료를 제공하며, 공간적 제약을 극복할 수 있다는 장점이 있다 본 논문은 웹에 기반한 교육적 활용의 한 모델로서 웹기반 교육평가시스템의 설계 및 구현에 관한 것이다. 웹기반 교육평가시스템은 기존 시스템들의 문제점이 되고 있는 문제출제 기능의 미비점을 해결하여 웹 상에서 문제를 출제할 수 있는 온라인 출제방식과 오프라인에서 작성한 문제를 업로드하여 재사용하는 업로드 출제방식을 모두 갖추어야한다. 또한 문항분석 기능을 갖추어 학생이 풀이한 결과에 대한 각종 분석 지표를 제공하여 교사는 난이도 조정이나 문항의 수정을 통하여 문항에 피드백을 할 수 있어야 한다. 본 논문에서는 이러한 요구사항을 모두 반영하는 시스템을 설계하고 PHP 스크립트 언어와 호환성이 좋은 MySQL데이터베이스를 이용하여 구현하였다.

  • The purpose of this study is to explore directions for improvement of teaching at college of engineering based on analysis of differences from course evaluation of students and instructors. Data was collected from 86 instructors' ratings on courses and their 3004 students' ratings on courses at college of engineering in a two-year, a three-year college and a University from 2010 to 2013. The results of the survey indicate significant differences in the statistics from the several questions between the instructors and the students as well as between the course in a two-year, a three-year college and in a University. First, instructors' self evaluation of the course is higher than students' satisfaction ratings of the course on the average. Instructors' self evaluation are high on the questions 'The subject was proper for the course', 'The course provided the latest theory and trend of the field', and 'Fairness and objectivity about the exams and the assignments'. Also, the difference between Instructors and students on the questions is significant in the statistics. The professor must make sure that students know well how to organize the course content and the method for feedback to test result and homework. Second, instructors have higher satisfaction ratings on the six questions and students have higher satisfaction ratings on the one question('Make students participate in the class effectively') at a two-year and a three-year college. However, students have higher satisfaction ratings on the three questions('Make students participate in the class effectively', 'Concern about students' learning process', and 'Use of E-learning and media equipments') and instructors have higher satisfaction ratings on the one question. It means instructors at a University feel pressure on a teaching and they are unsatisfied with their teaching skills. Third, the result of comparing six parts of the questions shows that students' satisfaction ratings are higher on 'Students participation' and 'Application of media equipments' parts whereas instructors' self evaluation are higher on 'Exams and assignments' part. Fourth, the question 'Make students participate in the class effectively' is significant in statistic based on comparison of instructors and students, and comparison of in a college and a University. Students' satisfaction ratings are higher than instructors' self evaluation.

  • Objective : Doctors who treat women in childbed have to pay attention to postpartum blues and depression which women in childbed can suffer from, as well as recovery of physical function. Methods : Subjects were 107 females who admitted in Woosuk Hospital of Oriental Medicine from September, 2000 to October, 2001 and made out the question paper within 10 days after delivery. The paper included EPDS(Edinburgh Postnatal Depression Scale) and many items known to be the factors related to postpartum blues and depression. Results : The rate of postpartum depression assessed by EPDS was 16.8%. As the result of analysis, there were significant statistic corelations between each group assessed by EPDS and age parity relation with husband yes or no living with parents-in-law. But there were no significant corelations between each group assessed by EPDS and education religion yes or no occupation delivery method sex of infant marriage type yes or no rearing the infant. Conclusions : We recognized that insufficiency- of delivery experience and stress due to bad adaptation after delivery are possible to be risk factors of postpartum blues and depression. More research should be taken on the corelation between postpartum depression and yes or no living with parents-in-law, because this result is opposite to the trouble between mother-in-law and daughter-in-law. In addition, more research is needed on corelation between physical condition, oriental-diagnosis of women in childbed and postpartum depression.

  • Purpose: Firefighters were subjected to be exposed to 24-hour shiftwork and high level of job stress, but there is little study of fire fighters about between Job Stress and Psychological stress in Korea. This study was performed to evaluate job stress of fire fighters grouped by different job types and analyze the health effect of job stress by using a PWI-SF(Psycho-social Well-being Index, Short Form). Methods : This study was to measure the degree of job stress and socio-psychological stress of firefighters working at 119 safety center and analyze the relationship between job stress and mental health, through self-administered questionnaire survey on 918 fire fighters working at fire department located in Korea, during October in 2008. Question items of the questionnaire consist of general characteristics, job stress, and socio-psychological stress. Job Stress Measurement Scale for Koreans was used to measure job stress, while PWI-SF used for socio-psychological stress. Collected data was analyzed through frequency analysis, ${\chi}^2$ test, one-way ANOVA, correlation analysis, multi-regression analysis using a statistic program, SPSS/10.0 Ver for Windows, and statistical significance level was 0.05. Result : Accordingly, this paper is written for the purpose of scrutinizing the reason of 119 rescuers' job stress and Socio-Psychological stress. This thesis tries to analyze a problem and provide contents through many variables concerned and theoretical investigation with the actual research of questionnaire. The results of the study are summarized as follows : Fire fighters feel relatively high stressful in their performance. Job stress, organizational commitment and burnout did not have been influence upon by individual cases such as economic condition, regular exercise etc. Finally, as a result of step by step regression analysis, the variable that can explain Socio-Psychological stress the best was negative emotion scale(NE). Conclusions : It is necessary to conduct repeated studies in the future, since the study implied that there was a contrary relationship between job stress and socio-psychological stress. In order to reduce job stress and maintain better mental health, it is more important than anything else to help firefighters have willingness and efforts to sustain a healthy life, so the development of various programs and education to raise their awareness should be implemented.

  • 본 연구는 소방관의 정신건강 향상을 위한 기초 자료의 수집을 목적으로 문헌 연구와 선행연구 결과들을 근거로 다음과 같은 연구 문제를 설정하여 연구하였다. 첫째, 소방관의 인구통계학적 특성과 PTSD 간에 어떤 관련성이 있는가? 둘째, 소방관의 인구통계학적 특성과 회복탄력성 간에 어떤 관련성이 있는가? 셋째, 소방관의 Posttraumatic Stress Disorder (PTSD)와 회복탄력성 간에 어떤 관련성이 있는가? 본 연구에서 사용한 측정도구는 회복탄력성 측정 척도, 외상후 스트레스 장애 측정 척도였다. 수집된 자료를 분석하기 위해 상관분석과 회귀분석을 실시하였고, 이런 분석은 SPSS (PASW Statistic) 22.0 프로그램을 사용하였다. 본 연구의 결과를 요약하여 연구문제별로 제시 하면 다음과 같다. 첫째, 소방공무원의 인구통계학적 특성은 PTSD에 유의한 영향을 미치는 것으로 확인되었다. 선행연구들과 일치하는 결과로서, 실효성 있는 방안의 마련이 시급함을 시사한다. 둘째, 소방공무원의 인구통계학적 특성은 상담경험만이 회복탄력성에 유의한 영향력을 미치는 것으로 확인되었다. 이는 소방관들의 회복탄력성 수준이 낮아져 있는 상태를 의미하며, 향상을 위해 상담 교육의 강화가 필요함을 시사한다. 셋째, 소방공무원의 회복탄력성 수준은 PTSD에 유의한 영향을 미치는 것으로 확인되어 PTSD의 보호 요인의 역할을 하는 것으로 나타났다. 하위 요인별 접근에서는 자기조절력이 유의한 영향력을 미치는 것으로 확인되어, PTSD로부터 보호를 위해 자기조절력을 강화하는 상담 교육이 필요함을 시사한다.
