Purpose of this research is considering activation way of stagnant railroad education. This research investigated domestic railroad education present condition and foreign countries' developed railroad college's education example by method of study. This research is going to produce railroad specialist who can achieve active and leading role base growth of railroad education and railroad industry development through link with resemblant railroad learning.

For Probabilistic Reasoning Ability is useful to predict uncertain fact from information, it's getting more important. But when we consider the actual condition of teaching Probabilistic Reasoning Ability, it doesn't correspond with its importance. So the purpose of this study is, by developing Basic Contents of Probabilistic Reasoning Teaching; by developing and applying Probabilistic Reasoning Teaching Program, to study how the application of it effects the progress of the student's Probabilistic Reasoning Ability.

We associate a positive integer n and a subgroup H of the group G(n) with a polynomial $J_{n,H}(x)$, which is called the Galois polynomial. It turns out that $J_{n,H}(x)$ is a polynomial with integer coefficients for any n and H. In this paper, we provide an equivalent condition for a subgroup H to provide the Galois polynomial which is irreducible over ${\mathbb{Q}}$.

This study was conducted to examine to causes and symptoms of stress and factors influencing stress management of workers in beauty shops. 811 people who were working in the shops located in Daegu City and Kyungbuk Province were selected as subjects of this study. Data were collected from April 10, 2000 to July 10, 2000. The results of this study can be summarized as follows. According to general characteristics of the respondents, female was 90.8%. 42.1 % of them was in their twenties and 73.7% of them did not marry. 57.5% of the respondents grew up in big cities and 41.1% had no religion. 63.6% was graduated from junior colleges. 44.6% of them worked for below I year and 33.9% earned below four hundred and ninety thousand won per month. 55.8% of them was satisfied with their work aptitude, while 34.2% was not satisfied with it. In the case of satisfaction level with working environment, ‘common level’ was 46.3%, while 12.8% of them was unsatisfied with it. In the case of stress level by factors of stress related to working, male was higher (9.34 $\pm$ 2.38 points). Those who grew up in towns or villages and those who belonged to the middle class showed high stress level. Those who married and those who graduated from high school also displayed high stress level. It also appeared that monthly income influenced the stress level related to working.. The extent of stress level influencing physical causes appeared in order of health condition, education level, sex, satisfaction level with work aptitude, economic status, and working hours. The extent of stress level influencing whole organizational level appeared in order of satisfaction level with work aptitude, working hours, education level, health condition, and sex. The extent of stress factors influencing depressed feeling of stress symptom appeared in order of working hours, sex, amount of smoking, absence due to stress, age, health condition, and education level. The extent of influencing factors on active stress management appeared in order of satisfaction level with work aptitude, health condition, size of the shop, drinking, sex, and the number of day off. The extent of influencing factors on avoidable stress management appeared in order of age, absence due to stress, drinking, health condition, and sex.

Let $D{\subseteq}E$ be an extension of integral domains with characteristic zero, I be a nonzero proper ideal of D and let H(D, E) and H(D, I) (resp., h(D, E) and h(D, I)) be composite Hurwitz series rings (resp., composite Hurwitz polynomial rings). In this paper, we show that H(D, E) satisfies the ascending chain condition on principal ideals if and only if h(D, E) satisfies the ascending chain condition on principal ideals, if and only if ${\bigcap}_{n{\geq}1}a_1{\cdots}a_nE=(0)$ for each infinite sequence $(a_n)_{n{\geq}1}$ consisting of nonzero nonunits of We also prove that H(D, I) satisfies the ascending chain condition on principal ideals if and only if h(D, I) satisfies the ascending chain condition on principal ideals, if and only if D satisfies the ascending chain condition on principal ideals.

To enhance the administrational efficiency and for university facility and space management to be public, this research suggests a competent and an objective evaluation system and index. The study will assist national and university finances to contribute towards advanced education. Furthermore, figure out the space management condition of national university by utilizing the evaluation system, and through that suggesting efficient special management method. According to the result of this study, evaluation system for university facility can be widely divided into seven categories; system preparation, members conference, propriety of space allocation, propriety of management system, space use ratio, time control of space use, imposition index of surplus use. Based on these subdivisions, the space management category contains 19 evaluation items and the marking system allows perfect score of 100 points. In result of examining space management condition using the evaluation system, space management was well enforced in research focused university group where as in education centered university group, it shows relatively low enforcement. It also illustrated that efforts of evaluation items were required in categories of imposition index of surplus use and special use ratio in order for efficient space management.

This study was designed to observe the nutritional knowledge, dietary life, and health condition in the middle school students. The subjects of this study were sampled out from co-ed middle schools in Seoul. The results of this study are summarized as follows: 1. The subjects take breakfast everyday by 50.4%, and their lunch depends very largely upon a lunch box by 95.2%. They take supper every evening by 79.0%. 2. The nutritional knowledge of subjects exhibits a significant difference by sex and region 3. The physical health condition of students exhibits a significant difference by sex and grade. 4. The mental health condition of students also exhibits a significant difference by sex, grade, and region. The school is required to endeavour for the student to have a correct understanding of nutritional knowledge form good dietary life. The government also should exert incessant efforts for school meal supply for their balanced nutrition.
