The effect of Thuja Biotae water extract on lipid composition, blood glucose, cholesterol, triglyceride and lipid hydroperoxide was studies in rabbits. In the animal fed Thuja Biotae water extract. blood glucose, cholesterol, triglyceride and lipid hydroperoxide was lower values than the control group. The lipid composition of plasma was not great differencies, but palmitic acid C?? was very elevated with higher than 50%, n-3/n-6 ratio was higher than 0.3 and P/S ratio washigher than 4.0. It assumed that Thuja Biotase water extract affected the blood glucose, cholesterol and triglyceride level lowering.

In this study, the heat transfer coefficient and heat stress and the flow characteristics according to the shape of pipe interior in Plate Heat Exchanger is studied by a numerical method using Design-Space. One of the most common heat exchangers that is mainly attached in vehicles is studied. Analysis is performed by comparing the results for plate heat exchangers with those for cylinder heat exchangers. In order to increase the effectiveness of heat exchangers, thermal conductiom, material, and thermal stresses in plate heat exchangers are investigated.

Recently a number of researches have been performed for the various methods of shape recognition of objects. An algorithm was developed for the recognition fo shape of arbitrary objects using ultrasonics. It was possible to measure the distance, the thickness and the real shape of the objects as well as the image of them using the experimental method developed here. Thus, the following results were obtained: (1) the basic algorithm for the recognition of shape of arbitrary objects can be applied to the real structures in the industry, (2) the error of measurement using the current method in within 1-6% compared to the real shape, and (3) in order to obtain the more accurate results, the minor errors in the algorithm and for the incident waves are being studied.

For the past 20 years, there has been a substantial increase in the percentage of women going to colleges and universities in Korea: the statistics indicate that the male and female ratio changed from 87.3% to 12.2% in 1952 to 73.9% to 26.1% in 1974. Inspite of the increasing trend, some academic observers recently began to voice their opinions against higher education for women on the basis that Korean women, regardless of their education in an occupation or public life. The following trends partially support this opinion. First, the tendency of female students concentrating their major fields on a limited number of specializations, such as teachers' education, language, arts, nursing and medical technology, is a contrasting phenomenon with male students, who are more or less evenly distributed throughout all the areas of specialization as their major fields. Second, the remarkable increase in female labor participation for the past 10-15 years is largely contributed by women in the agricultural sector and manufacturing industries, as the percentage of women with higher education have shown not as much of an increase in the labor market as that of these with elementary level or less education. Furthermore, the percentage of women in professions and managerial occupations which would require college education for qualification toward has decreased from 2% in 1960 to 1.8% in 1970. Thirdly, a survey of Ewha graduates concerning their attitudes toward women's social role and college education presents revealing results of their conservatism and resignation sex equality and occupational roles. These findings certainly contradict the egalitarian principles of modern higher education and human potentials. However, there are now growing trends among female college students, with the awareness of changing sex roles, of taking seriously their future occupations and other social roles in addition to marriage. They are showing a greater concern for developing their potentials for professions and egalitarian roles for society, realizing the need for overcoming socio-cultural limitations as well as personal inertia. These are signs calling for new directions in women's education in Korea by introducing women studies programs which are designed to liberate women from the culturally conditioned state of self-awareness and the traditional status and role.

The effect of dietary- milk casein, magnesium and calcium on the total cholesterol level of Rabbit was examined using isocaloric and isonitrogenous diets. The gain in body weight, liver weight, blood sugar, magnesium and calcium in relation to cholesterol level was studies. The results are summarized as follows: 1. The gain in body weight (g/day) of Rabbit was 23.21 for control, 28.57 for A, 24.29 for B and 23.21for C groups. 2. Liver weight (g) of Rabbit for the control, A.B and C group were 30.4, 5, 35.3, 3, 30.5, 5 and 35.4, 3, respectively. 3. Serum cholesterol levels(㎎/100㎖ serm) of the control, A,B and C groups were 71.55, 57.5, 73.5 and 84.3, respectively. 4. Liver cholesterol levels (㎎/100㎖ liver fats) of the control A,B and C groups were 255.0, 675.4, 257.8 and 540.3, respectively. 5. The contents of magnesium in serum for control was 5.61㎎%, for A, 12.l6㎎%, for B, 8.51㎎% and for C groups 9.73㎎%. 6. The contents of calcium in serum for control was l6.31mg%, for A, 35.67㎎%, for 8, 29.66㎎% and for C groups, 25,65㎎%. 7. The contents of blood glucose ㎎/100㎖ blood of the control, A,B and C groups were 70.3, 100.5, 96.4, and 88.5, respectively. 8. According to the regression and correlation coefficient in blood components of Rabbit, there are negative correlation between calcium, and liver cholesterol, and there are negative correlation between calcium, magnesium and serum cholesterol.

Recently a number of researches have been preformed for the various method of shape recognition of objects. An algorithm was developed for recongnition of shape of arbitrary objects using ultrasonics. It was possible to measure the distance, the thickness and the real shape of the objects as well as the image of them using the experimental method developed here. Thus the following results were obtained; 1. the basic algorithm for the recognition of shape of arbitrary objects can applied to the real structures in the industry. 2. the error of measurement using the current method is within 1-4% compared to the real shape, 3. The errors in this research can be classified into three categories. 1) There are errors in the scanning for the curved-surface. 2) There are errors in the algorithm. 3) There exist error in the oblique inclidence. 4. Therefore, if errors in the oblique incidence and errors in the curved-surface are considered, more accurate recognition system can be established.

The effects of dietary calcium, magnesium on the serum cholesterol concentration in rabbit was studied for a period of 21 days using isocalories and isonitrogenous basal diet. It is investigated that the serum cholesterol level lowering 10-30% by feeding with calcium and magnesium containning diet was performed. There was no effect for the total protein, but there was some sort of effect for albumin and globulin. Particulary, the beta-globulin concentration was decreased by calcium and magnesium containning diet. It is, also, investigated that there is almost no effect for the electrolytes concentration transport and phenomena in the cell through magnesium and calcium containning diets.
