  • Cochlodinium polykrikoides 적조생물은 우리나라 연안에서 가장 빈번하게 적조를 유발하는 생물이다. 적조는 식물플랑크톤의 급격한 번식(algal bloom)으로 발생하기 때문에 적조를 유발하는 적조생물에 대한 최적의 성장조건 정보가 가용하다면 정확한 적조성장 모형 구성이 가능하며, 적조 발생예측에도 활용할 수 있다. 그러나 적조 성장에 영향을 미치는 인자가 빛, 수온, 염분, 영양염류 농도 등으로 다양하고, 적조성장을 제어하는 함수형태가 다양하기 때문에 실험조건의 최적 성장조건에 대한 연구 성과를 활용하여 적조 수치모형에서 활용할 수 있는 최적 성장모형을 구성한 연구는 매우 미흡한 수준이다. 본 연구에서는 우리나라의 대표적인 적조생물에 해당하는 Cochlodinium polykrikoides 적조생물의 최적 성장조건에 관한 연구 자료를 이용하여 다양한 함수형태에 따른 최적 매개변수 추정 및 오차비교 분석과정을 거쳐 적조 모형에서 바로 활용할 수 있는 최적 성장모형을 개발 제시하였다. 개발된 성장모형은 실험조건에서 추정된 최적 성장모형이기 때문에 현장자료를 이용한 모형의 보정 및 검정과정에서 본 연구결과로 제시된 최적 함수형태, 최적 매개변수 및 보정 매개변수의 범위 등을 기본 정보로 활용할 수 있으며, 실험조건과 현장조건의 차이 평가에도 활용할 수 있다.

  • This research was conducted to provide basic document on efficient health promotion behavior program that elementary school students can use from elementary school course to enhance health promotion behavior for healthy life by checking out the degree of the most influential factor for health promotion behavior about elementary school students who establish lifelong health habit, and by checking out the relation between the degree of self-efficacy and health promotion behavior. The number of subjects of this research was 598. They were all elementary school students from the sixth grade students of the 5 cities of the Kyeong Nam province. We conducted questionnaires and did statistical analyses by using 592 papers which were suitable for date analyses with SPSS. The conclusions were as follows; A. The degree of self-efficacy The degree of self-efficacy of elementary school students was more than average. The degree of self-efficacy on physical activity was the highest and the degree of self-efficacy on self-fulfillment was the lowest. The degree of self-efficacy of girl students was comparatively higher than that of boy students. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest in health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. B. The degree of health promotion behavior Although the degree of health promotion behavior of elementary school students was a bit lower than the degree of self-efficacy, it was higher than average. The degree of health promotion behavior on physical activity was the highest. But the degree of health promotion behavior on health of their own was the lowest. The degree of health promotion behavior between girl students and boy students was the same. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest In health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. C. The relation between self-efficacy and health promotion behavior When the degree of self-efficacy was high, the degree of health promotion behavior was high too. So there was high positive relationship between self-efficacy and health promotion behavior. Physical activity showed the highest relationship. The order of strong relationship run as follows. Relationship with others, self-fulfillment, management of stress. The higher self-efficacy which was a recognizable factor on health behavior, the higher the degree of health promotion behavior. It is being revealed that many modem chronic diseases are cause by accumulated careless attitude on harmful health habit and lack of self-control. The behavior of keeping healthy and enhancing health is more firm when they have high self-efficacy which is believing their own conviction. So, When we teach elementary school students health promotion education at school, we should try to enhance their own self-efficacy rather than just instill simple information about health. By doing so, we can help them change their attitude on health. Then, they could enjoy life-long healthy life.

  • 산업안전보건법 제48조에 따른 유해·위험방지계획서 대상 현장의 재해예방을 위해 안전보건 지킴이를 활용한 계획서 확인 모니터링 및 자율안전체계 확보를 위한 계획서 자체 확인 등 여러 대책 시행에도 불구하고 건설공사의 재해율을 살펴보면 연평균 100여 명의 사고사망자가 유해·위험방지계획서 대상현장에서 발생하고 있다. 물론 대상 현장이 다른 건설현장과 비교하여 위험요인이 다수 존재한다는 것을 고려한다 하더라도, 위와 같은 결과는 재해를 예방하고자 작성되고 활용되는 유해·위험방지계획의 효과에 의문을 갖게 한다. 건설현장에서는 관리자가 근로자, 장비, 시설물에 대한 안전점검을 시행하지만, 시간적, 공간적으로 작업의 내용과 상황이 계속 변화하는 건설업의 특성상 지속적이고 즉각적인 안전관리가 어려운 실정이다. 설계 및 시공성 검토가 큰 영향을 미치고 있다는 사실을 인지하고, 설계 오류의 사전발견 가능성을 높이고 효율성을 높이기 위하여 BIM(Building Information Modeling)을 활용하는 방안이 최근 많이 논의되고 있다. 이에 본 연구는 현재 건설업에서 실행하고 있는 유해·위험방지계획서 관련 연구 문헌 조사, 재해현황분석 및 설문조사를 통해 현장 활용도 저해요인을 도출하였으며, 이를 개선할 수 있는 BIM 기능과 저해요인과의 상관성을 파악함으로써 적용 필요성을 제시한다.

  • After signing the WHO FCTC in 2003, South Korea ratified the FCTC in 2005. This study was conducted to provide data on toxic constituents that can be used as useful information for the level of exposure to Korean smokers. Emissions data from five brands of cigarettes were tested under the ISO and "Canadian Intense (HCI)" smoking regimes, respectively. We conducted an analysis of 25 compounds containing nicotine, tar, carbonyls, phenolics, volatile organic compounds (VOCs), and semi-VOC cigarette smoke. Tar and nicotine showed levels of 4.3 to 5.8 mg/cig and 0.4 to 0.5 mg/cig, respectively, which are within the range of tolerance presented in ISO 8243. In the case of carbonyls, formaldehyde was detected within a range of 8.2 to $14.3{\mu}g/cig$, and acetaldehyde was present within a range of 224.7 to $327.2{\mu}g/cig$ under the ISO smoke regime. Crotonaldehyde was not detected under the ISO regime, and all of the carbonyls showed values 2.3 to 4.5 times higher under the HCI regime than those under the ISO regime. Catechol, which showed a level of 47.0 to $80.5{\mu}g/cig$ under the ISO regime and 117.5 to $184.7{\mu}g/cig$ under the HCI regime, was the highest constituent among the phenols. The amount of isoprene was 91.7 to $158.3{\mu}g/cig$ under the ISO regime and 221.0 to 377.0 under the HCI regime. To summarize, most of the constituents showed a tendency to be detected at levels 2 to 4 times higher under the HCI regime than under the ISO regime. Above all, these results represent the first analysis in Korea from an independent institute of tobacco companies under accreditation of ISO 17025.

  • The lack of characteristical understanding of the Home Economics Education will have difficulty in achieving the goal of the Home Economics Education. To allow the Home Economics Education class in school contribute toward the enhancement of the quality of life, it is inevitable to reinforce the recognition of the importance and necessity of the Home Economics Education and to newly propose a directional guidance forward the coming 21st century. The purpose of this study was to provide basic data for planners of the future Home Economics Education by surveying research administrators in charge of programming the overall school curriculum. This study was conducted under the following procedure to have the outcome as follows ; 1. Answers from respondents of age over 50 or careers over 16 years tended to grasp the goal of Home Economics Education in relation to the enhancement of quality of life rather than to the accumulation of knowledge, skill or capacity. 2. Of all the surveyed, 9.64% regarded Home Economics Education as an essential part of school education and the positive ratio was higher with younger respondents. 3. To the question asking if the high school Home Economics Education could have influence on one's capacity, 97.2% of the answerers said yes. The respondents with career under 15 year showed 100% of positive agreement in this matter and of age under 40 marked much higher ratio of 98.84% than the elders. 4. The overall recognition of the necessity for separate sections in Home Economics Education programmed in accordance with the 6th Revision of High School Curriculum displayed a considerably high ratio, with a little differences among age and job groups. The purpose of this study is to analyze and understand adolescents'culture, thereby to provide fundamental information for Preventive Education for Adolescents'Problems in Home Economic Education. 745 articles collected in computer communication service were used for the analysis. The data were analyzed by frequency and percentage using the SPSS/PC+computer program. The most important results of this study were as follows ; 1) Concerning 'Adolescent's Problems's, problems such as violence, homicide and robbery were treated with the greatest frequency. It was also analyzed that the older generations are highly inclined to understand adolescents'culture as a negative one, for example, 'delinquency'or 'immaturity'. 2) Although the area of 'Adolescents'Education'was treated most frequently reflecting the high educational concern in our society, the significant part of those articles were on wrongful educational administration. As much as 70.6% of the articles analyzed were on 'Education'and 'Problems'. Thereby it may be concluded that the other areas such as health, activities, worries, values and harmful environments ere treated respectively as only a 'subculture'or'fragmentary culture'. The articles containing correlations and interactions among them and certain alternative proposals were very rare. 3) The areas such as 'Worries and Counselling'and 'Health'were occupying only a small portion of the articles. The articles which were treating the practical worries and their resolutions were even rarer. 4) 'Values'of the adolescents tended to be viewed by the older generations very negatively. It was also found that the older generations gave the tendency to see the 'consumption culture'of the adolescents as a kind of 'counter culture'or'subculture'.

  • 최근 유해한 환경요인에 의한 질병발생 등 사람의 건강에 부정적인 영향이 중요하게 다루어지고 있다. 특히, 방사성 물질이며 폐암 1급 발암물질로 알려진 라돈 노출 영향에 관한 연구가 활발해지고 있다. 한국에서도 2018년 1월 1일 이후, 공동주택을 신축할 때 라돈측정이 의무화되었다. 라돈농도를 측정해 지자체에 제출하여야 하며 주민이 볼 수 있는 곳에 공고해야 한다. 라돈은 다중이용시설에 관한 권고 기준만 있었으나 이제는 주택에도 권고기준을 설정하기로 했다. 따라서 이제는 환경영향평가 단계는 물론 사후환경조사에서도 라돈을 관리할 수 있도록 해야 한다. 라돈농도 등의 환경정보와 라돈의 위해성 등 건강 정보도 공유할 수 있어야 하며, 이를 위해 환경영향평가 단계에서 보건전문가의 참여가 필요하다. 환경영향평가 과정에서 라돈이 인체 건강에 미치는 영향을 고려할 수 있도록 토양, 대기질, 위생 공중항목 등을 개선하여야 한다. 라돈의 농도가 권고기준치 이상이면 대안을 마련하고 저감방안을 마련하여야 한다.

  • It is well known that smoking habit is hazardous to health, especially for juvenile. The present study on smoking behavior of high school students in Seoul has two major objectives. The first objective is to find out the smoking behavior of high school students in Seoul. Toward this objective, individual's smoking experience has been examined as ever smoking and never smoking. The second objective is to determine the variables associated with their smoking behavior at the individual, family and school environment levels. For the data collection, the survey was carried out for the four high schools in Seoul from September 15 through October 15, 1982. The major findings are summarized as follows: 1. Smoking behavior of the students 1) Out of 1,278 respondents, 30.2% of them were found to be current smokers and 29.3% of them were former smokers. This implies that around 60% of school students in Seoul have experienced smoking. 2) A significant differences in the current smoking rates between two types of the school students were shown as 19.3% for day-time school and 42% for night-time school. 3) In terms of the current smoking behavior, the students who don't live with parents were higher in smoking rate than those of the living with parents. 2. Attitudes and knowledge about smoking 1) Attitudes of students toward smoking in high school days were shown that around 17% of them agreed with it and around 64% of them disagreed with it. 2) Around 99% of the respondents answered that their smoking is harmful for health. A source of the information about negative effects of smoking on health was 'Radio and TV' (23.9%) as the most influential, 'school teacher' (20.9%), 'Newspaper' (18.2%) and so on. 3. Behavioral analysis for the current smokers 1) The factors affected for motivation in the first smoking were 'curiosity' (59.7%), 'temptation of friend' (19.7%), 'resistance feeling, (7.1%), 'merely interest and pleasure' (6%) respectively. 2) The time of the first smoking was 'third grade of Junior-high school' (31.5%) as highest, 'first grade of Senior-high school' (23.7%) and 'second grade of Junior-high school' (14.7%). 3) An average daily number of cigarettes consuming of current smokers was seven cigarettes. 4. Family and school-mates influences on individual's smoking behavior 1) The data revealed a significant relationship between student's smoking and their parent's smoking behavior. Around 75% of the students whom both parents are smoking have experienced cigarette smoking. It was found that the individual's smoking behavior was influenced by his sibling. Around 65% of the students whom brothers are smoking have experienced cigarette smoking. 2) The 'Smoking-Index' of friendship network or a group explained individual's smoking behavior in the group. The result of dyad analysis of smoking behavior in the friendship network showed that a high score of 'Smoking-Index' tended to be explained an adoption of smoking behavior at the individual level in the group. on the other hand, a low score of 'Smoking-Index' explained non-smoking behavior in the group.

  • 목적 일 지역 소아청소년과 외래를 방문한 부모들의 자녀의 발열에 대한 발열공포의 수준 및 부모의 발열염려 정도와 대상자의 특성 간의 관련성을 파악하고자 함이다. 방법 소아청소년과 외래를 방문한 부모 151명을 대상으로 구조화된 자기기입식 설문지를 이용하여 자료를 수집하였다. 수집된 자료는 기술통계 및 카이제곱 검정을 통해 분석하였다. 결과 약 50%의 대상자들이 $37.8^{\circ}C$를 발열의 최저기준 체온으로 그리고 $38.9^{\circ}C$를 고열의 최저기준 체온으로 정의했다. 약 3/4의 대상자들이 발열의 해로운 효과로 경련과 뇌손상을 언급했으며, 발열에 대해 '매우 염려'를 하였고, 자녀의 발열 시 1시간 이내에 체온을 다시 측정하였고, 미온수 목욕을 제공했으며, 열성질환이 있는 경우 잠자는 아동을 해열제를 주기 위해 깨웠다. 부모의 자녀 발열에 대한 염려는 이전 열성 경련 경험 여부와 한 자녀 가정의 부모와 통계적으로 유의한 관련성이 있었다. 결론 소아청소년과 외래를 방문한 부모들에게도 발열공포가 광범위하게 존재하고 있었다. 부모들을 위한 발열 및 발열 관리 교육 프로그램의 개발과 평가가 요구된다. 의사와 간호사가 부모들의 발열관련 정보의 1차적 근원임을 고려할 때 건강관리제공자들은 부모들의 발열에 대한 비현실적인 공포를 경감시키는 데 중요한 역할을 하여야 할 것이다.
