Objects: In July 2 2010, a diarrhea outbreak occurred among the workers in a company in Gyeungju city, Korea. An epidemiological investigation was performed to clarify the cause and transmission route of the outbreak. Methods: We conducted a questionnaire survey among 193 persons, and we examined 21 rectal swabs and 6 environmental specimens. We also delegated the Daegu Bukgu public health center to examine 3 food service employees and 5 environmental specimens from the P buffet which served a buffet on June 30. The patient case was defined as a worker of L Corporation and who participated in the company meal service and who had diarrhea more than one time. We also collected the underground water filter of the company on July 23. Results: The attack rate of diarrhea among the employees was 20.3%. The epidemic curve showed that a single exposure peaked on July 1. The relative risk of attendance and non-attendance by date was highest for the lunch of June 30 (35.62; 95% CI, 2.25 to 574.79). There was no specific food that was statistically regarded as the source of the outbreak. $Bacillus$ $cereus$ was cultured from two of the rectal swabs, two of the preserved foods and the underground water filter. We thought the exposure date was lunch of June 30 according the latency period of $B.$ $cereus$. Conclusions: We concluded the route of transmission was infection of dishes, spoons and chopsticks in the lunch buffet of June 30 by the underground water. At the lunch buffet, 50 dishes, 40 spoons, and chopsticks were served as cleaned and wiped with a dishcloth. We thought the underground water contaminated the dishes, spoons, chopsticks and the dishcloth. Those contaminated materials became the cause of this outbreak.

본 연구는 대학도서관 사서가 지각하는 근거기반실무 지식과 조직문화 인식유형이 혁신행동에 미치는 영향을 파악하기 위한 서술적 상관관계 연구이다. 연구결과는 다음과 같다: 근거기반실무 지식은 조직문화 인식, 혁신행동과 통계적으로 유의한 양적 상관관계가 있었다. 근거기반실무 지식이 높을수록 관계지향, 혁신지향, 업무지향의 조직문화 인식이 높은 것으로 나타났다. 근거기반실무 지식은 연령, 교육 정도, 고용 유형, 직위, 학술지의 정기적 읽기, 학술대회 참여 여부에서 유의한 차이가 있었다. 혁신행동에서 유의한 차이가 나타난 변인은 연령과 학술대회 참가 여부 이었다. 근거기반실무 지식에 영향을 미치는 변인은 교육정도, 학술지의 정기적 읽기로 나타났다. 혁신행위의 인식은 연령과 학회참석과 유의적 관계가 있었다. 대학도서관 사서의 혁신행동에 영향을 미치는 변인은 근거기반실무 지식, 혁신지향 조직문화, 위계지향 조직문화로 나타났다. 특히, 위계지향 조직문화 인식은 부정적 영향을 미치는 것으로 나타났다. 대학도서관 사서들의 혁신행동을 이끌어 내기 위해서는 소통과 협력의 혁신적 조직문화를 조성하며, 근거기반실무 적용을 위해 사서의 연구활용능력을 강화하고, 연구 관련 활동을 촉진하는 다양한 교육프로그램의 개발과 지원이 조직 및 도서관계 차원에서 필요하다.

본 연구는 영화 리뷰 값이 1000개 이상인 673개의 영화를 대상으로 영화 장르별로 관객들이 느끼는 감정 어휘의 분포를 탐색하고 영화 흥행도와 감정 어휘의 관계를 파악하는데 목적이 있다. 분석을 위해 네이버 영화 리뷰를 크롤링하고 감정 어휘 사전을 활용하여 7개의 대표 감정 어휘, 영화 티켓 판매액, 영화 관람 관객 수, 상영 스크린 수, 한 스크린 당 영화 관람 관객 수, 영화의 장르, 영화의 영문 이름으로 구성된 데이터를 생성하였다. 연구 목적을 위한 분석은 상관관계 분석 방법과 Parallel coordinates 시각화 분석 방법을 사용하였다. 연구 결과로는 첫째, 장르에 따른 영화 흥행도를 분석하여 영화 흥행도가 가장 높은 장르는 코미디이고 가장 낮은 장르는 호러라는 결과를 확인하였다. 둘째, 모든 장르에서 'Happy'와 'Surprise'의 값이 높게 나오지만 다른 장르들에 비해 판타지 장르의 영화는 지루한 감정이 많이 느껴지고, SF장르의 영화는 화나는 감정이 많이 느껴진다는 결과를 확인 하였다. 셋째, 모든 장르의 감정 어휘 별 상관관계를 분석하여 Disgust'의 값이 높아질 때 'Anger'의 값도 높아지고, 'Happy'의 값이 높아질 때 'Surprise'의 값은 낮아진다라는 결과를 확인하였다. 넷째, 영화 흥행도에 따른 감정 어휘를 분석하여 영화 흥행도와 'Happy'는 선형 관계이지만 영화 흥행도와 'Fear'는 비선형 관계인 것을 확인 하였다.

최근 대학교육은 교육 패러다임의 변화와 함께 학습자 중심의 교육 모델을 강조하고 있다. 본 연구는 대학 강의평가의 개방형 응답을 토픽 모델링으로 분석하여 학생들의 다양한 의견을 탐색하고 교육의 질을 향상시키는데 목적이 있다. 이를 위해 비수도권 대학의 2017년부터 2022년까지 강의평가 결과를 바탕으로 총 45,001개의 개방형 응답을 전공과 교양으로 구분하여 단문에 최적화된 BTM(Biterm Topic Modeling) 분석을 진행하였다. 분석 결과 전공 강의는 "비대면 수업경험에 대한 태도", "질문과 토론에 대한 태도", "출석과 성적평가에 대한 태도", "실습활동 및 발표에 대한 태도", "소통과 협업에 대한 태도"로 구분되었고, 교양 강의는 "비대면 수업경험에 대한 태도", "성적 및 평가에 대한 태도", "출석 및 수업계획서에 대한 태도", "학문적 지식과 흥미에 대한 태도", "소통과 질문에 대한 태도"로 구분되었다. 학생들의 다양한 피드백을 분석한 본 연구결과를 토대로 전공과 교양 강의의 특성을 비교하고 강의개선 및 학습경험을 향상시키는데 도움이 될 수 있는 인사이트를 얻을 수 있을 것이다.

Exploring the risk factors of adolescent suicide is important for effective suicide prevention. This study explored the clustering of adolescent suicides based on six risk factors: mental disorder, broken family, depression, anxiety, previous suicide attempts, and deviant behaviors. Using 173 student suicide reports obtained from the Ministry of Education, we evaluated the associations between suicide and variables related to mental disorders; dysfunctional family life; depression and anxiety; previous suicide attempts; deviant behaviors such as drinking and smoking; and school life characteristics, including attendance and discipline, problems within the past year, and incidents prior to suicide. In addition, reports of warning signs just before suicide were included in the analysis. The two-stage cluster analysis classified the students into three clusters: the silent type (cluster 1; 48.55%), in which no risk factors were observed; environmental-risk type (cluster 2: 24.28%), which featured a high frequency of broken households, deviant behaviors such as smoking/drinking and running away from home; and depressive type (cluster 3: 27.17%), which featured a high frequency of mental health problems such as depression, anxiety, and suicide attempts. Identifying the sub-types of adolescent suicide may help to inform tailored suicide prevention and intervention strategies in school.

This study examined the cognitive and social development of children of low income, disabled mothers. Sixty-four disabled mothers and their 3- to 5-year-old normally developing children participated. Children's IQ, receptive vocabulary, and social adaptive ability were measured with Korean-Wechsler Preschool and Primary Scale of Intelligence (Park et al.,1996), Peabody Picture Vocabulary Test-Revised (Seoul Community Rehabilitation Center, 1995), and Social Maturity Test(Kim & Kim, 1995), respectively. Results showed that IQ and receptive vocabulary scores were lower than average and that verbal IQ was positively related to shared reading time and library use; verbal IQ was negatively related to duration of child-care attendance. Children's social quotient was higher than average and positively related to mother's employment status and amount of books in the home.

The purpose of this study is to investigate the perception about STEAM education of primary teachers who have developed and applied STEAM education to their students through teacher training program. For this study, 101 among 172 attendance are responded to questionnaire of three categories consisting of development and application teaching material for STEAM instruction, and spreading STEAM education. The major findings are as follows: First, when primary teachers develop materials for STEAM education, they consider applicabilities in real classes. Second, they feel the burden of time when they develop STEAM material. Third, they think that their own program has significant educational effectiveness and that students enjoyed the program. Especially, they think that STEAM education program can raise students' interest about learning. Fourth, primary teachers point out the constraints for application of STEAM education program, which are lack of expertise and difficulty acquiring class time. Fifth, primary teachers evaluate the effect of STEAM education program on primary education is positive, and they answer that we need many teaching materials for STEAM education, operating as a regular curriculum, and securing budget. In order to spread STEAM education in field of primary education successfully, administrators have to consider and reflect the voice of teachers.

본 논문에서는 현직 교원연수에 적합한 가상교육시스템을 설계하고 구현하였으며, 구현된 시스템을 직접 현장에 적용하여 평가하였다. 범용 가상교육시스템이 지나치게 많은 불필요한 기능을 가지고 있어서 오히려 운영하기에 불편을 주는 반면 본 시스템에서는 불필요한 기능을 없애고 유용한 기능만으로 구성하였다. 본 시스템은 학습자, 교수자, 운영자, 컨텐츠간의 상호작용성에 보다 많은 관심을 두었다. 상호작용성을 높이기 위하여 학습자정보찾기, 연수출석, 연수자전달사항, 연수과제제출, 분임토의, 사이버카페, 접속통계 메뉴 같은 것을 둔 것이 특징적이다. 본 시스템을 2년에 걸쳐 554명의 교원에게 직접 적용한 결과 이수율 95%를 얻었다.
