The purpose of this study was to criticize (through available documents) the lecture in English at colleges. It is necessary that a study of English is emphasized in the era of internationalization. But, the indiscreet extension of lecture in English without consideration of the purpose, principle, and philosophy of college's education needs reflective thinking. This study criticized four dimensions, in other words the effectiveness of lecture in English, criteria of internationalization and college's competition of lecture in English, social inequality of lecture in English, and the harmfulness in the value of Korean language of lecture in English. First, most researches expressed the indiscreet extension of lecture in English was not effective in both students and professors. Second, many scholars and agencies on the internationalization and college's competition excluded the lecture in English as criteria. Third, the indiscreet extension of lecture in English had the possibility of social inequality. And fourth, the indiscreet extension of lecture in English had harmfulness in the value of Korean language and Korean's thought. College's education is an ivory tower in society. So, colleges should discard the thought that extension of lecture in English is the best way. Colleges should keep the purpose, principle, and philosophy of college's education.

Objectives: This study was performed to examine the factors affecting re-smoking in male workers. Methods: A self-administrated questionnaire survey was conducted during April 2003 to examine the smoking state of 1,154 employees of a company that launched a smoking cessation campaign in1998. Five hundred and eighty seven persons, who had stopped smoking for at least one week, were selected as the final study subjects. This study collected data on smoking cessation success or failure for 6 months, and looked at the factors having an effect on re-smoking within this period. This study employed the Health Belief Model as its theoretical basis. Results: The re-smoking rate of the 587 study subjects who had stopped smoking for at least one week was 44.8% within the 6 month period. In a simple analysis, the re-smoking rates were higher in workers with a low age, on day and night shifts, blue collar, of a low rank, where this was their second attempt at smoking cessation and for those with a shorter job duration (p<0.05). Of the cues to action variables in the Heath Belief Model, re-smoking was significantly related with the perceived susceptibility factor, economic advantages of smoking cessation among the perceived benefits factor, the degree of cessation trial's barrier of the perceived barriers factor, smoking symptom experience, recognition of the degree of harmfulness of environmental tobacco smoke and the existence of chronic disease due to smoking (p<0.05). In the multiple logistic regression analysis for re-smoking, the significant variables were age, perceived susceptibility for disease, economic advantages due to smoking cessation, the perceived barrier for smoking cessation, recognition on the degree of harmfulness of environmental tobacco smoke, the existence of chronic disease due to smoking and the number of attempts at smoking cessation (p<0.05). Conclusion: From the result of this study, for an effective smoking ban policy within the work place, health education that improves the knowledge of the adverse health effects of smoking and the harmfulness of environmental tobacco smoke will be required, as well as counter plans to reduce the barriers for smoking cessation.

The purpose of this study was to examine the knowledge of dental hygiene students on smoking and their state of smoking in an attempt to assist dental hygienists to develop good anti-smoking education programs, as dental hygienists should play a critical role in conducting an anti-smoking campaign and education. The subjects in this study were dental hygiene students in six different colleges located in Seoul and Gyeonggi province. After a survey was conducted from April to June, 2007, the answer sheets from 1,322 students were gathered and analyzed. The findings of the study were as follows: 1. As for the reality of smoking, 82.7% were nonsmokers, and 12.2% had been smokers in the past, 5.1% were smokers, which accounted for 5%. Regarding when they started smoking, 47.1% and 35.3% started it in middle school and high school days respectively. So 80% or more began smoking as middle and high schoolers. As to a daily amount of smoking, 36.8% smoked five or less cigarettes, and 22.1% smoked six to 10 cigarettes, 14.7 % smoked 11 to 15 cigarettes. Concerning motivation of smoking, 51.5% did it out of curiosity, and 26.6% intended to get rid of stress. Among the smokers, 80.9% had ever tried to quit smoking, and as for the reason, 51.0 % wanted not to develop a disease in the future, and 25.0% weren't in good health. In regard to what made them fail to give up smoking, 49.0% answered they were increasingly stressed out, and 24.0 % were tempted by others. 2. As to the impact of smoking on the body and illness, the largest group believed it affected unborn babies, and the second largest group was aware of the harmfulness of secondhand smoking. The third largest group thought it exercised an influence on the lung and respiratory ailments, and the fourth largest group believed it was detrimental to health. The fifth greatest group thought tar was harmful to the body. They didn't know well about whether smoking deteriorated the sense of taste, but were well cognizant of the harmfulness of smoking. 3, Their knowledge on the impact of smoking on the body and diseases was evaluated by academic year and in consideration of whether they were smokers or not.

There are a variety of factors affecting measured compressive strength of hardened concrete. One of them is the end surface condition of concrete specimen. So, many capping methods have been developed for the specimen to meet the end condition requirement of ASTM C 39. A series of experimental strength comparison study was carried out using several representative capping methods, including pad capping method which is one of unbonded elastomeric capping system and was newly adopted in the ASTM standard. A comparison was also focused on their economy, convenience, harmfulness, etc.

본 연구는 방사선 이해교육에 대한 유치원 교사들의 인식과 요구를 분석하고, 방사선에 대한 유아교육기관에서의 올바른 이해와 방사선 노출로 인한 유아안전 대책 마련을 위한 기초자료를 제공하는데 의의가 있다. 본 연구에서는 2014년 8월 C시와 G시의 유치원 교사 300명을 대상으로 설문지를 배부하여 회수된 158명의 자료를 분석하였다. 본 연구의 결과는, 첫째, 유치원 교사들의 방사선에 대한 이해수준 낮았으며, 방사선에 대한 이해수준이 낮을수록 방사선의 일반적인 유해성과 피폭유해성에 대한 심리적 불안감은 높은 것으로 나타났다. 둘째, 유치원 교사들의 방사선 이해교육 정도는 낮았으나, 유치원 교사들의 방사선 이해교육의 필요성 및 요구는 높은 것으로 나타났다. 결론적으로 본 연구는 방사선에 대한 올바른 이해를 돕기 위한 교사교육이 시급함을 시사한다.

화학사고의 발생을 감소시키고, 예방하기 위한 공정안전관리(PSM) 제도는 우리나라의 경우 1996년부터 시행되었다. 그러나 PSM 제출대상인 기존 21종 물질에 대한 규정량과 새로이 추가된 브롬화수소 등의 독성물질의 규정량에 대한 타당성 검토가 미흡하여 많은 문제점이 발생되고 있다. 본 연구에서는 25종의 PSM 제출대상독성물질의 규정량을 국내 외 공정안전관리제도와 관련된 규정량과 비교 검토하였다. 그리고 흡입독성, NFPA 지수 등으로 구성된 독성 유해 위험성 식을 제안하여 고위험, 중위험, 저위험의 3등급으로 독성물질을 분류하고, 규정량의 조정에 반영하였다. 본 연구결과의 규정량 개선안은 유사 공정안전관리제도의 규정량 차이로 인한 사업장의 혼란과 부담 완화 및 합리적 개선에 도움을 줄 것으로 기대된다.

This study was conducted to provide basic data to develop a smoking prevention and non-smoking education program. Data were collected, using a questionnaire, from 438 male middle school students living in Chunchon, Kwangwon- do. The data collection period was from September 2 to 30, 2000. The questionnaire used to measure the subjects' knowledge and attitude toward smoking was based on the guideline for the contents of tobacco smoking surveys for the general population designed by WHO. The collected data were analyzed using the SPSS-Win program. The results were as follows. 1. The subjects' average score for smoking knowledge was 58.52 out of 100 points. 2. The subjects' average score for attitude toward smoking was 63.54 out of 100 points. 3. Smoking knowledge of the subjects was significantly different by their grade (F=9.187, p=.000), father's smoking behavior (t=2.261, p= .024), aware of harmfulness of smoking (F=8.911, p=.000). The subjects' attitude toward smoking was significantly different by mother's smoking behavior (t=-2.557, p=.011), brother's smoking behavior (t=-3.959, p=.000), having a smoking friend or not (t=-4.422, p=.000), subjects' smoking experience (t=-8.304, p=.000), present smoking behavior (t=7.001, p=.000), quantity of smoking (F=3.297, p= .041), abstinence period of smoking (F=3.858, p=.013), thinking about smoking behavior (F=20.999, p=.000), aware of harmfulness of smoking (F=20.964, p=.000), and amount of drinking (F=8.316, p=.000). 4. There was a significant correlation between subjects' knowledge and attitude toward smoking (r=.514, p=.000).
