And it was for helping to devise a policy and to develop a program for industrial workers' health promotion by understanding the consciousness behavior level of industrial workers in our country and the related factors which are under the influence of it and health promotion behavior. The summary and conclusions are as follows. 1. In health promotion score level by related factors, the health diagmosis level score was 7. 37(81.9/100) of the perfect score 9, nutrition level score was 7.00(77.8/100), health education behavior level score was 6.00(66.7/100), exercise behavior level score was 6.01(66.8/100), occupational disease knowledge level score was 6.00(66.7/100). 2. Health diagnosis behavior level was significantly high when the age is older, when the occupation term is longer, when the economic status is better. And wjem tje satosfoed degree for vocational aptitude, working environment, and the education contents. 3. Nutrition (dietary habit) status level was high in men, in the age group of 40 over, in the group of having their spouse, in the group of being paid over one million won a month, in the upper economic classes (P〈0.001). It was also high in graduates middle school and in daytime workers (P〈0.05). 4. Health education behavior level was high in the older ahe hroup, in a single life (separation by death, divouce, separation) and in the longer occupation term(P〈0.001). 5. Exercises behavior level was high in men, in the workers who are paid 500～990 thousand won a month, in the better economic classes(P〈0.01). 6. Knowledge level on an occupational disease was high in men, in the older age group, in the group of having a spouse, In the workers who are paid 500～990 thousand won a month, in the group of having a longer occupation term, and in the residents living not in a large city(P〈0.01). 7. When health status was higher, health promotion behavior, behavior level, health diagnosis (P〈0.001), nutrition(P〈0.05), health education behavior (P〈0.05), exercise behavior(P〈0.01) and the knowledge level on an occupation disease was high. 8. The main factors which are under the influence on the degree of practicing healthy life were the level of knowledge and behavior, sex, his/her health status, and the satisfied degree of working environment. These variables could explain it 18.0%. 9. The factors which are under the influence on health promotion behavior and behavior levels were the variables of the satisfied degerr of education contents, sex, health knowledge, economic status, health status, occupation terms, monthly income, working tiredness. These variables could explain it 21.3%. By these results, it is inportant for industrial workers' health promotion to level up the health diagnosis behavior, dietary habit considering nutrition, behavior on health education, behavior for exercise, and knowledge on an occupational disease. Especially we should develop the proper program considered sex, health status, satisfied degree of working environment and education contents, economic status, eccupation terms, knowledge on health, and behavior level. Because health promotion business gies in gear with productivity promotion.

This study was conducted from March 1, 1996 through June 30, in order to provide basic data for devising a policy for school health especially students health promotion and for developing of an education program. Middle school students were 1000, high school students were 2000 and a total of 3000 students were selected randomly among the boys/girls/middle/high schools which are in Seoul, Pusan, Taegu, Pohang, Suwon, Kyungsan, Milyang and a town or subcountry. The summary and conclusion are as follows. 1. In general characteristics of respondents, 51.8% were girl students, 33.7% were middle school students, 66.3% were high school students. 37.2% were living in a medium and small city, 89.1% were middle classes, 43.6% were having no religion, 27.3% were buddhists. 2. As a result of analyzing, exercise, nutrition, personal behavior, knowledge of health education and behavior level which are the factors promotion, exercise level were 3.61 of the perfect 9(40.1/100), nutrition level were 3.71(41.1/100), personal hygiene were 6.89(76.6/100), health education level were 5.1(58.9/100), all of the them are low level. 3. Judging from characteristics, in case of exercise behavior level, It was far higher in boy students than in girl students, in middle school students than in high school students. It was respectively higher than other groups in the second graders of middle school, in the first graders of high school, in the residents who live in a big city, in the high classes in the buddhists. 4. The students level against disease was average 9.11 of the perfect score 14(65.1/100). The level of disease consciousness was high in girl students by characteristics, in the second graders of high school by grades, in high school students than middle school students. 5. In health status, 55.4% were healthy, 7.9% were unhealthy. It was respectively higher than the other groups in boy students, in middle school students, in the residents who live in a big city, in high classes of life level, in buddihists, in higher education level of parents. 6. Judging from the factors of health status and health promotion and the degree of significance, there's a significant differences between exercise and dietary life as P〈0.001, in personal hygiene as P〈0.05, in health education an P〈0.01. 7. Knowledge on disease, health promotion behavior level were average 19.42 ± 4.01 of the perfect score 50(38.8/100) this score was too low. As for characteristics, the level between variables was statistically significant in the higher life level, in the higher parents education level, in the happier family. 8. Judging from health status, knowledge on disease, health behavior level, knowledge and health promotion behavior level significantly in the better health status, in the better school record. 9. As a result of the multiplex regression analyzing the factors which were under influence on health status, the variables like exercise, school record level, the degree of family happiness, nutrition, grades, the members of family influenced much and its persuasive power was 10.2%. The factors which are under the influence on the health promotion were exercise, satisfied degree of education, health status, the degree of family happiness, knowledge on disease, the usage of physical training, sex, the number of the family members, mother's education level. It’s explained power was 21.3%. promotion were high We should develop a text book and an education program to study exercise, nutrition(dietary life), personal hygiene, knowledge on disease and health systematically. As far as health education irrespective city and locality without considering the entrance exam for high school and university we should execute it continuously. To do this, it’s important to cultivate and secure qualified men of ability who can teach things related health promotion and the related subject, that is, health or health promotion subject should be established in middle and high school curriculum necessarily.

The buffer and backfill are important components of the engineered barrier system in a high-level waste repository, which should be constructed in a hard rock formation at a depth of several hundred meters below the ground surface. The primary function of the buffer and backfill is to seal the underground excavation as a preferred flow path for radionuclide migration from the deposited high-level waste. This study investigates the hydraulic conductivity and swelling pressure of Kyungju Ca-bentonite, which is the candidate material for the buffer and backfill in the Korean reference high-level waste disposal system. The factors that influence the hydraulic conductivity and swelling pressure of the buffer and backfill are analyzed. The factors considered are the dry density, the temperature, the sand content, the salinity and the organic carbon content. The possibility of deterioration in the sealing performance of the buffer and backfill is also assessed.

이 연구에서는 초등학교 5학년 영재학급 학생 14명을 대상으로, 과제의 개방도와 학생들의 인지수준에 따라 TS 활동에서 나타나는 언어적 상호작용이 어떤 특징을 보이는지 알아보았다. 연구 결과, 학생들은 과제의 개방도가 낮은 안내형 TS 활동보다는 개방도가 높은 개방형 TS 활동에서 훨씬 많은 언어적 상호작용을 보였고, 상위 수준의 상호작용도 안내형 활동보다는 개방형 활동에서 많았는데, 이런 결과는 언어적 상호작용의 거의 모든 하위 범주에서 나타났다. 또한, 안내형 과제를 수행하는 과정에서는 행동참여를 지시하거나 자기만족을 나타내는 언어사용 빈도가 높은 반면에, 개방형 과제를 수행하는 과정에서는 행동참여를 권유하거나 불만을 나타내는 빈도가 높았다. 학생들의 인지 수준에 따른 언어적 상호작용의 특징을 보면, 인지수준이 높을수록 상호작용의 빈도가 높고, 다양한 유형의 언어적 상호작용이 이루어지며, 상위수준의 상호작용이 많은 것으로 나타났다. 그러나 학생들의 인지 수준과 과제의 개방도는 학생들의 언어적 상호작용에 복합적으로 영향을 주는 것으로 나타났다. 즉, 인지 수준이 높은 학생일지라도 안내형 활동에서는 상호작용의 수준이 높지 않았으며, 개방도가 높은 활동이라도 인지 수준이 낮은 학생들은 참여도가 낮고 상호작용의 수준도 높지 않았다. 이는 개방가 높은 과제가 학생들의 사고를 자극하여 상위 수준의 상호작용을 이끌어낼 수 있지만, 그 효과는 학생들의 인지 수준에 따른 한계가 있음을 의미한다. 따라서 과제 활동에서 인지 수준이 낮은 학생들의 사고를 자극하고 참여도를 높이기 위한 과제 개방도의 조절과 교수 전략의 개발이 중요한 추후 과제라 생각된다.

Heights of a platform above the rail for the passenger train in the country are classified into two categories such as the low level (500mm; mainline) and the high level (1,135mm; metropolitan subway line) platforms. In order to operate similarly both a mainline railroad and a metropolitan subway line, as the requisite door safety system, it is necessary to develop the doorstep equipment of the rolling stock regardless of both the low and high level platforms. In this study, the application of doorstep equipments to use mixed with two types of platforms are examined on the supposition that the train only for the low level platform stops in the both low and high level platforms.

According to Pierrehumbert (1980), two level tones - H and L - are enough in representing intonation of intonational languages. But in Korean, high fall and low fall boundary tones, both of which must be represented as HL％ in intonational phonology as in Jun (1993, 1999), are distinct not only acoustically but also functionally. The same is true in the case of high level and mid level boundary tones, which must be represented as H％ in intonational phonology. In this paper, I conducted two identification tests to provide crucial evidence that H and L are not enough in intonational phonology. The results of the identification tests show that categorical perception occur between high level and low level as well as between high fall and low fall. Based on this fact and the results of the acoustic analyses in Lee (1999, 2000), I strongly propose to adopt one more level tone - M - to represent Korean boundary tones.

This paper describes the development of a piezoelectric level switch, which aims to effectively monitor the level status in high ambient temperatures. In order to adjust the impedance near the resonant frequency and temperature characteristics, the effect of the case and backing layer materials on its performance was analyzed using the finite element method (FEM). The suggested prototype new level switch has three heat-sink plates attached to SUS bar of 230 mm long, and case of PEEK which contains PZT sensing part. To illustrate the validity of this level switch, 10 samples are prepared and investigated the sensing performance through the high and low temperature ambient.
