The purpose of this study was to evaluate comfort in a classroom. The questionnaire was given to 120 university students in the classroom. On the basis of previous studies, the evaluating factors on comfort in a classroom were selected and they were lightness, glareness, air freshness, dust, odor, loudness, distracting sounds, humidity and temperature. The scale of them was used five voting scales. The results showed that the lightness was the most important one among the evaluating factors because a classroom is an environment to have to see many things.

The purpose of this study is to find out how to use dynamic geometry software such as the Geometer's Sketchpad in elementary math classroom. Fist of all, I reviewed dynamic geometry software's property. Then I considered methods to improve geometry education using this software. Some researchers proposed three types of using the software. But I think using the software and developing instructional materials is different. So, I proposed two types of developing instructional materials using the software and two representative examples.

학교수학의 내용 중에는 수학적으로 깊은 의미를 가지고 있지만, 교실수업에서는 자명한 것으로 취급되어 그 중요성이 간과되고 있는 것이 있다. 본 연구에서는 원주율의 값이 상수라는 익숙한 사실을 그 구체적인 예로 들어 수학적 의미를 재음미하는 한편, 아르키메데스가 원주율을 계산한 방법 속에서 교육적 시사점을 찾아 탐구주제로서의 원주율의 가치를 부각시키고자 한다.

전통적인 교수.학습의 형태를 벗어나 새로운 환경인 웹을 통한 교육이 이루어지고 있다. 그러나 대다수의 웹을 통한 교육들은 단지 웹 환경이라는 이름 하에 평면적인 의사소통의 한계를 벗어나지 못하고 있는 실정이다. 이에 대한 대안으로 본 연구에서는 가장 대중적인 실시간 의사소통 프로그램인 채팅 프로그램을 기반으로 교육용 대화 애플리케이션을 개발하였다. 이 애플리케이션이 교실 내.외적으로 열린교육에 대한 지대한 관심을 쏟고 있는 최근의 학교 교육에 하나의 학습 도구로서 활용될 수 있음을 기대한다.

교사의 자리 배치와 교우관계 형성의 관계성을 밝히려는 목적으로 2016년에 일반계 고등학교 3학년 문과반 학생 28명을 대상으로 사회 네트워크 분석을 하였다. 연구결과 학급 내 하위네트워크가 4개를 발견하였고, 친밀도가 가장 낮은 학생을 전체 네트워크의 구조적공백에 위치하였을 때, 긍정적인 교우관계를 확인하였다.

본 연구는 민간 직업훈련 기관의 훈련생 모집에 영향을 미치는 요인을 분석하기 위해 훈련 등록한 대상들에게 설문조사를 실시하였다. 이를 위해 접근성 요인(교통편, 주차장 등), 시설 요인(교실 크기, 시설 환경 등), 상담자 역량 요인(응대 태도, 서비스 지식, 상담 Skill 등), 비용적 요인(훈련비, 훈련비 지원 유무 등), 교육 요인(교육 편성 내용, 강사진 등)으로 나누고 각 요인들이 훈련 등록에 어떠한 영향을 미치는지 분석 하였다.

Objectives:Within the normal reproductive cycles of women, dramatic fluctuations of sexual hormones occur in the premenstrual and menopausal periods. In both periods, women are vulnerable to mood disturbances and show several somatic complaints. Based on these common clinical profiles and physiological changes, a relationship between vasomotor symptoms and the premenstrual syndrome has been suggested. However, attempts to establish such a link have yielded inconclusive results. The purpose of this study was to investigate the association between histories of premenstrual syndrome and menopausal vasomotor symptoms within different menopausal stages. Methods:This cross-sectional study recruited Korean women aged 45-64 years who were perimenopausal and postmenopausal from 16 branch offices of the Korean Association of Health Promotion. All subjects completed self-report questionnaires that asked about a history of premenstrual syndromes, vasomotor symptoms, and several other variables. Results:A total of 1054 participants(361 perimenopausal women and 693 postmenopausal women) completed the study. Severity of premenstrual symptoms significantly correlated with postmenopausal vasomotor symptoms, only in late perimenopausal(r=0.213, p=0.010) and early postmenopausal women(r=0.246, p<0.001). After adjusting for several factors related to vasomotor symptoms, a history of premenstrual syndrome was a significant predictor of moderate to very severe vasomotor symptoms in late perimenopausal(OR=5.197, p=0.005) and early postmenopausal women(OR=3.017, p=0.010). Conclusions:This study suggests that a history of premenstrual syndrome/premenstrual dysphoric disorder is differentially associated with vasomotor symptoms in the menopausal stage. Prospective studies with larger population are needed to confirm these findings

Objectives : Shift work has been known to cause various health problems by making it difficult for humans to adapt to their natural circadian rhythms. In particular, shift workers tend to complain of sleep difficulties associated with work schedules, and sometimes use alcohol as a self-medication to induce sleep. To date, no clear mechanism has been identified regarding the link between shift work and sleep, between shift work and drinking. This study aims to confirm the relationship between shift work and sleep, and to analyze whether the change in sleep caused by shift work causes drinking. Methods : This study included 11360 people (5704 men and 5656 women) among the Korean National Health and Nutrition Survey data in 2014, 2016 and 2018. The work type between 6am-6pm was defined as day work, and other work types were defined as shift work. Using logistic regression analysis, the relationship between shift work and sleep quality, shift work and high risk drinking, drinking amount at 1 time, drinking frequency were analyzed. In addition, we analyzed whether sleep mediates the relationship between shift work and drinking using mediated analysis. Results : Shift work showed a significant negative relationship with sleep quality in men and women (male OR=1.37, 95% CI 1.11-1.70, female OR=1.26, 95% CI=1.05-1.50). There was no significant relationship between shift work and alcohol in the case of men, but in the case of women, there was a significant positive relationship between shift work and the number of alcohol consumption (OR=1.34, 95% CI=1.04-1.72). When mediation analysis was conducted, it was found that women's sleep quality partially mediated the relationship between shift work and the frequency of drinking. Conclusions : The results of this study suggest that shift work causes sleep difficulties, and in the case of women, drinking can be induced through the partial mediating effect of sleep. Considering that women are more likely to choose drinking as a coping method for sleep problems, more active interventions for female shift workers are needed.
