The frequency distribution and morphological characteristics of tissue mast cells in the various tissues of normal domestic animals (bovine, swine, dog and chicken) and systematically infected (Hog cholera, Canine distemper and Newcastle disease) animals were studied. The results were as follows: 1 In cattle, density of mast cells was higher in foetus (bovine) and young animals than in adults Differences in frequency distribution among individual animals were also observed. 2. In chicken, the highest number of mast cells was found in age group of 15 to 40 days, the moderate number in age group of one to 10 days, and the lowest number in age group of 40 days or older. 3. The morphologically, mast cells were usually round, ovoid, spindle, oval and irregular, and particularly in ovary of bovine, it was usually round and ovoid forms. 4. The largest numbers of mast cells were shown in ovary of bovine, intestine of swine and dog, and proventriculum of chicken. 5. In the systemic infections, the number of mart cells usually tends to increase.

An experiment was conducted to examine the effect of different feeding levels of concentrate (85, 100 and 115%) and age (15, 18 and 24 month) on fatty acid synthetase (FAS) activities in the 4 locations of adipose tissues (intermuscular, ITER; intramuscular, ITRA; kidney, KIDN and subcutaneous, SUBC) of 36 Korean native cattle (Hanwoo) steers. Steers of 100% feeding group were fed the amount of concentrate to meet the daily nutrient requirements, and the steers of second and third groups were fed concentrates at the levels of 85% and 115% of that of control group, respectively, up to 18 month of age. Thereafter, the steers were fed ad libitum up to 24 month of age. Feeding level of concentrates tended to affect the FAS activity of various adipose tissues in Hanwoo steers of each age. The FAS activity of ITER adipose tissue had the decreasing trend as the age of steers advanced while those of ITRA and SUBC adipose tissues had the slightly increasing tendency with age. The FAS activity based on the pooled data increased with the feeding level of concentrates (115%) in which the activities from all 4 adipose depots were higher than those with the lowest (85%) feeding level. Similar trend was observed from the pooled data of feeding level of concentrates by age of steers in which the FAS activities for all 3 ages were increased with feeding levels of concentrates. But the response in the FAS activity to the feeding level varied with age.

The purpose of this study was giving some helpful datas in analysing the degree of anteroposterior jaw disharmony with the 'Wits' appraisal. The cephalograms of 105 Korean adults with normal occlusion ranging from 17 to 20 years of age and 76 Koreans with various malocclusion ranging from 12 to 24 years of age were studied and analyzed statistically. The results were as follows; 1. The mean value of 'Wits' appraisal in normal occlusion group was -0.82mm in males and -0.17mm in females. 2. There was no significant difference between the males and females in normal occlusion group. 3, The mean value of 'Wits' appraisal in Angles class II malocclusion group was 2.67mm and higher than normal group. 4. The mean value of 'Wits' appraisal in Angles class III malocclusion group was -8.11 mm and lower than normal group.

Maximizing profit is the most significant object of commercial places. Especially for some places where its atmosphere is main concern of customers like $Caf{\acute{e}}s$, interior design is crucial. Thus it needs to evaluate human emotion and preference. Human Sensibility Ergonomics which is recently signified in various fields is an attempt to quantitatively analyze factors of human sensibility and apply it to design operation. This study attempted to infuse human sensibility ergonomics into $Caf{\acute{e}}$ interior design and analyzed preferable $Caf{\acute{e}}$ interior design factors. Because most $Caf{\acute{e}}s$ have their own target customers, so we assumed four different target customer groups divided by their age and gender groups in each age group. As a result, the difference of each group could be examined. Middle-aged group and males have main interest in the intensity of luminance, i.e. the brightness, whereas youths and females attach importance to both quality of light and color. In addition, there is a tendency for middle-aged group and males to see $Caf{\acute{e}}$ as a public place while young people and females recognize $Caf{\acute{e}}$ as a place for entertainment. Taking the result of this study into consideration can lead to successful $Caf{\acute{e}}$ interior design for specific target customers.

The purpose of this study was to investigate the natural menopause age of middle-aged women in Korea and to analyse various factors affecting them. For the collection of date, 1,140 women aged between 45-54 were selected through stratified sampling technics in Seoul and at a rual area in Kyong KiProvince. They were interviewed from Nov. 1 through Dec. 31,1987 by use of questionnaires made after pilot study had been performed twice. Among them the final subjects for analysis were restricted to only those who had experienced menopause or irregular menstruation during the past one year, the number of which was total 410:206 in urban and 204 in rural area. For the analysis, menopause age was used as dependent variables while fertility variables, socio-economic variables, bio-physical varibles, and insight of life variables were classified as independent variables. Dependent variables such as menopause was tested and analysed by descriptive statistical methods(e.g., frequency, percentage, mean, $X^2-test.$ t-test, ANOVA). The relation between menopause age and independent variables was analysed by use of Pearson's correlation coefficients. For the analysis of various factors affecting menopause age, multiple stepwise regression method was used. The obtained results are summarized as follows: 1. The natural menopause age of Korean women were 47.2 mean age: it was 47.7 and 46.7 mean age in urban and rural area respectively, which revealed that the former was later then the latter by one year. And the recollective error on menopause starting age between the menopause group and the group who had experienced irregular menstruation during the past one year was 0.4-0.7 year. 2. The main factors affecting the menopause age were (1) the duration of marital life, (2) the duration of oral pill use, (3) insight of life and economic status, (4) educational background. (5) menarche, (6) usual menstruation amount, (7) electic charge. and (8) area. These factors. altogether, could explain $18.4\%$ of factors related with menopause, and they took the high percentage in the order mentioned.

This study examined the various functions of public libraries, as well as user satisfaction and needs. We targeted 6 public libraries in the Seoul and Gyunggi area. After 280 library users were surveyed, the collected data were analyzed with an SPSS for Win 14.0 statistics program, where we used frequency, percentage, mean, T-test, One-way ANOVA, and Duncan's test. The major findings were as follows: 1) Half of the users used educational functional space, mainly in the 10-20 age group, who used it for educational purposes as a student or to prepare for getting a job. 2) There were gaps between the furniture arrangement and user preference since most libraries used a rigid system while users preferred a more flexible arrangement. 3) Space by space, public library satisfaction levels differed according to the users' gender and age. Satisfaction of the digital information room scored high, especially for users in their forties. Since public library users are diverse and require various functions, library interiors should be planned accordingly in terms of furniture arrangement and interior design. In particular, there was a gap between satisfaction by age groups, so libraries must account for community needs by considering the age group demographics of their surrounding areas.

The solids(supplementary food) consumption of 200 healthy infants aged from 4 to 6 months have been measured. Five groups were assigned to different feeding patterns. Breastfed group(BF, n=38), formula-fed group(FF, n=102) and mixed-fed group(MF, n=14) were fed breast milk, formula and mixed(breast mile+formula) from birth until 6 months of age respectively. Convert 1 group(C1F, n=14) and convert 2 group(C2F, n=32) were fed breast milk and mixed milk at 2 months of age respectively and were switched to formula thereafter. All infants received solids form 4 months of age. The energy intake from solids at 4 and 6 months averaged 59.1 and 110.3㎉/d among BF groups vs 151.9 and 239.3㎉/d among FF groups respectively. Intakes of protein, calcium and iron were 38-46$\%$, 34-44% and 25-37$\%$ higher in the FF than in the Bf group during the first 6 months. However, no significant differences were found in the intakes of energy and nutrient intakes from solids in all 4 groups excluding BF group(39$\%$). Although BF infant's nutrient intakes from solids were lower than other group's intakes, they intaked evenly solids from various food groups. As the age of infant had increased, the energy intake ratio from solids was cereals and dairy products was increased whereas energy intake ratio from meats, eggs, fruits and vegetables was decreased. TSC4, TSC6(the frequency score for the kinds of weaning food taken) showed no significant difference among 5 feeding groups but CIF-and C2F group's scores tended to be high. Consequently, these results suggest that BF group's solid intake pattern is more desirable and that Korean lactating Mother's dependence on commercial weaning food is too high.

Objectives: Despite the considerable interest in the increase in obesity particularly of socially disadvantaged group in Korea, how obesity varies according to various socio-demographic characteristics still remains largely unanswered. To further develop the understanding of obesity in Korea, the present study focuses on the possibility that the relationship between educational attainment and obesity varies across age. Methods: Using 2010 Korea National Health & Nutrition Examination Survey (KNHANES), this study divides the adults into male and female groups and examines the interaction effect of age and educational attainment on obesity through binominal logit models for each group. Results: The most educated male group is more likely to be obese than those who did not complete high school. And the relationship between male's educational attainment and obesity does not significantly change across age. In contrast to male's obesity pattern, female educational attainment has a significant negative association with obesity. The gap in obesity across educational groups converges after middle ages in female. Conclusions: Health policies should pay more attention to those who are more vulnerable to obesity risk in order to effectively reduce obesity.

This research attempted to examine whether there were differences in preference for the shoes according to fashion lifestyle and age by conducting survey on 200 women of 20s and 40s among the adult women who were expected to have interest in not only functionality but also aesthetic aspects of shoes. First, the results of comparing the preferences according to fashion lifestyles showed that those who pursued practical group preferred loafer, strap shoes, and baggy boots, indicating that they preferred low and comfortable shape of shoes which are easy to put on/take off and easy to coordinate with any clothes. Those who pursued personality group and ostentation group were more sensitive to fashion than practical group preferred high heel shoes, which could express their own personality, it would be great to have various designs by reflecting the trendy materials and details focusing on pumps, strap and walker boots which can express individuality and supplement the body shape and height as matching to the trendy clothes. Second, as women in 20s have tendency to show more preference of a certain trendy shoes shape than women in 40s, the shoes designs for 20s should focus on certain types of shoes preferred by them by varying materials and details, rather than having various designs. However, it would be great to show various designs for the shoes for 40s. Most of the 20s are the individual and complex fashion-seeking types while the 40s have the most of practical fashion-seeking type and the least of individual fashion-seeking type.

The purpose of this study was to analyze the differences in make-up behavior according to clothing involvement, age, and face satisfaction. Subjects of is study were the females in Seoul and Kyonggi, who were 20s and 40 $.$ 50s. Questionnaire was used as major method of gathering data. The data were collected from Sep. to Oct. in 2003 and analyzed by using SPSS 10.0 with various techniques such as the factor analysis, mean, percentage, cluster analysis, ANOVA, Duncan test, 1-test, Cronbach＇s $\alpha$, and $\chi$$^2$-test. The results of this study were as follows: 1. The consumers were classified into four categories by clothing involvement; high clothing involvement group, low fashion involvement group, middle clothing involvement group, low clothing involvement group. 2. The differences in make-up behavior according to the clothing involvement showed that make-up behavior was getting more aggressive as clothing involvement was getting higher. And generally Korean females thought the make-up was important. 3. The differences in make-up behavior according to the age revealed that 20s＇ make-up behavior was fashion oriented more than 40ㆍ50s, and 40ㆍ50s＇ make-up behavior was that they were taking a serious viewer than 20s＇ in interpersonal relationship oriented make-up behavior. 4. The result of differences in make-up behavior according to the face satisfaction was that no noticeable difference was found depending on the face satisfaction. This study revealed that the differences in make-up behavior according to clothing involvement and age were found and suggested that the cosmetic market segmentation could depend on clothing involvement market and two age group market such as younger and elder than 40ㆍ50s.
