Effects of irregular feeding on a 2 days cycle under an 80% energy restriction were examined on the growth rate, biochemical composition of liver and blood, and daily energy metabolism in 6-12 weeks old rats. The rats were divided into four groups which were fed an experimental diet for 38 days ad libitum (A) every day, 80% diet of group A every day (R80), 100 and 60% diets of group A on alternate days (R100-60), and 120 and 40% diets of group A on alternate days (R120-40), respectively. Body weight gain was significantly lower in group R120-40 than in the other groups. The weights of internal organs were lower in all the restricted groups than in group A. However, their weight ratios to whole body weight were not significantly different among all the groups. Differences in such daily energy metabolism as total energy expenditure per kg body weight were not significant between group A and group R80, which suggested that the rats in group R80 attained metabolic adaptation to the feeding conditions by diminishing their body size. On the other hand, the rats in group R120-40 changed total energy expenditure (TEE) and minimal energy expenditure (MEE) according to the amount of food ingested on alternate days. They maintained MEE on 120% diet days at a level comparable to that of the rats in group R80 and adapted the present irregular feeding conditions by decreasing total activity (TA). However, the decrease in TA brought about by irregular feeding over a long period of time is considered to be undesirable for health.

The purpose of this study is to know the degree of staling of cooked rice during storage by means of sensory test and to evaluate the degree of staling by the objective data by means of instrumental measurements. Rice samples were six varieties of rice with 2.4-27.2% apparent amylose content. These were cooked with various amount of added water and stored at 5°C for 0-48 h.
The staling scores by the sensory test increased during storage. The higher the amylose content and the less added water was, the higher the staling scores were. On the objective data the hardness, the breaking stress and the initial elastic modulus increased during storage, while the stickiness, the breaking strain and the degree of gelatinization decreased. However, no single data by the objective measurements fully corresponded to the staling scores. Therefore a multiple regression analysis was performed to express the staling scores as a criterion variable (Y) and the objective data as an explanation variable (X). As a result the following equation with high coefficient of determination (R'² =0.87) was obtained using the hardness (H) and stickiness (-H) measured by a texturometer : Y= 0.86 X (H) -3.15 X (-H) -0.48.

This study was conducted to analyze the actual conditions of the bathing habits and consciousness of bathing of Koreans living in urban apartments in Korea.
The results are as follows :
1) Seventy five percent of our respondents use the public baths because they have a sauna and because of the low temperatures in winter in the residential bathrooms.
2) Actual conditions of bathing in the residential bathrooms and the public baths change greatly depending on the season, whether it is summer or winter.
3) Taking a shower once or more a day has become a bathing habit in the bathroom of dwellings in summer.
4) Both Japanese bathing style and shower bathing style have been found to be the main bathing styles of the residents using the bathtubs in their dwellings.
5) The younger the residents are, the greater the tendency is to use the residential bathroom more than the public bath. The same tendency is observed among the Seoul residents.
6) The main purposes of urban apartment residents for using a public bath are to relieve fatigue and to cleanse themselves.
