Purpose:It has been known that the prognosis of a young woman's breast cancer is Poorer than the other woman However, the effect of age on the prognosis is not well-defined We performed this study to investigate age as a prognostic factor of breast cancer. Materials and Methods : A retrospective study was conducted for 3209 breast cancer patients who underwent operations in Department of Surgery, Seoul National University Hospital from January 1981 to December 2000. Patients were divided into two groups, young age(≤35) and old age(>35) groups. And tumor stage, histopathologic characteristics(such as histology, nuclear grade, histologic grade, hormonal receptor, etc), overall survival and disease free survival rates were compared between age groups. Results . The age ranged from 17 to 88 years. 396 patients(12.3%) were included in young age group(median=32) and 2813 Patients(87.7%) in old age group(median=47).There are more advanced stages and poor nuclear grades in young age group(p=0.000, p=0.003), By log-rank test, the young age group had poorer overall survival and disease free survival rates(p<0.05, p=0.0002). Although, the young age group had more advanced TMN stages(p=0.000) and poorer nuclear grade than the old age group(p=0.003) in multi variate analysis, the age was not a significant independent prognostic factor. (P=0.642)Conclusion: Our study showed that the age was not a significant independent prognostic factor.

The need for periodic investigation on human growth rate and somatotypes has been increased because the scientific development and environmental factors have effected a lot on them recently. This study aimed to investigate the changes of the 638 female somatotypes in the age of 18-54 obtained by direct and indirect measurement. The measurement data were divided into 4 groups early young women age group (18-54), late young women age group (25-34), early middle age group (35-44), late middle age group (45-54) and compared each other based on each group by age. The results obtained from this study were as follows: 1. According to Mollison Curve based on the early young women, items of depth decreased overall and pp.P. length & shoulder length increased as the age increased. The circumference, breadth and thickness tended to increase, especially waist girth and thickness of waist increased markedly. The data showed that the increase rate of thickness was higher than that of breadth. 2. Gradual somatotype changes were observed by overlapping projection drawings obtained by direct measurement. Compared with the young women, the middle aged showed lower should point depth and hip line & crotch depth line were lengthened significantly. No significant difference was observed in overlapping of the early young women and the late young women' figure, neither was in early middle aged and the late middle aged. 3. By overlapping the side view of the young women group (18-37) and middle aged group (35-54), no significant postural characteristics were found, while the back tended to bend forward and the abdomen and hip appeared to get fat.

The purpose of this study was to investigate the differences of sociocultural attitudes toward appearance, clothing and cosmetics purchasing behaviors according to male consumer's age group. The research method was survey and subjects were 656 male consumers. The results were as follows. First, three factors (appearance importance awareness, appearance internalization, and slimness importance awareness) were emerged on sociocultural attitudes toward appearance. Young age group showed higher level of appearance importance awareness and internalization than middle age group. Second, there were many differences on clothing purchasing behaviors by age variable. Young age group more importantly considered psycho-social purchasing motives, aesthetic selection criteria, and the internet as information source and purchasing place than middle age group. Whereas middle age group more importantly considered practical purchasing motives, practical selection criteria, and store display & salesman as information sources, and fashion outlet as purchasing place than young age group. Third, there were also many differences on cosmetics purchasing behaviors by age variable. Young age group used more and various cosmetics, and they more importantly considered skin improvement as purchasing motive, skin suitability and price as selection criteria, the internet as information source and purchasing place than middle age group. On the other hand, middle age group generally used fundamental cosmetics, and they more importantly considered skin protection as purchasing motive, quality as selection criterion, TV and store display & salesman as information sources, and discount store and cosmetics speciality store as purchasing places than young age group.

The purpose of this study was to confirm the difference of garment pressure and comfort depend on age group wearing the Korean skirt-band. A loadcell was used for measuring garment pressure, and 25 female subjects were chosen for each of young, middle, and old age groups. Garment pressure was measured in front, side, and back parts of the body. The results were as follows: 1. The younger the subjects, the greater the garment pressure. This suggests that the young age group wear the Korean skirt-band more tightly than needed. 2. The measurements of the pressure in 3 parts of the body were different. In young and middle age groups, pressure decreased from side to back, while in the old age group the order was side, back, and (rent. 3. The young age group felt high restriction of pressure. And the pressure in side part of body is the greatest among the three measurement.

The purpose of this study was to examine changes in the rate of occurrence of challenging behaviors in young children according to their increase in age. The study is based on the responses of teachers in child care centers(N=246). They were asked which 38 types of challenging behavior occur most among ages 2, 3, 4, or 5 in young children's classrooms. The major results of this study were as follows. First, the occurrence rates of young children's challenging behaviors were classified into 5 clusters; decreased(Cluster 1, Cluster 2, Cluster 3), maintained(Cluster 4), or increased(Cluster 5) according to increases in their respective ages. Second, the behaviors such as throwing tantrums and biting, evident in Cluster 1, decreased very rapidly from a very high occurrence rate by age 3. The classroom culture maladjustment behaviors such as running aimlessly around the classroom and shouting, apparent in Cluster 2, had decreased rapidly from a high occurrence rate by age 4. The intentional classroom disruptive behaviors such as dropping objects to create noise and the peer culture maladjustment behaviors studied in Cluster 3 decreased gradually from a rate of medium occurrence by age 5. These results revealed the discontinuity which a few young children exhibit. Third, hurting others, observed in Cluster 4 maintained a low occurrence rate from age 2 until age 5. Using inappropriate language and threatening others in Cluster 5 increased gradually from a low occurrence at 2 to a high rate of occurrence at age 5. By carefully examining the change of young children's challenging behaviors on the basis of objective data in terms of the continuity/discontinuity and increased/decreased rate of diverse challenging behaviors, we will be better able help teachers and parents to plan the instruction, prevention and intervention of young children's challenging behaviors.

This study investigates the relevance between the subjective age and clothing shopping orientation by adults women located in the cities of Seoul and Gyeonggi. The results are following. First, subjective age was identified with interest age, look age, and physical age. Customers were segmented into following five subdivisions: young activity group, actual age group, young appearance group, physical aging group and youth-oriented group. When the study examined differences between real age and subjective age, the study could see that they perceived themselves younger four years than real age- 50s: 7 years, 40s: 5 years, the latter half of 30s: 2.7 years and the former half of 30s: 1.7 years. Second, clothing shopping orientation was identified with planned shopping orientation, leisure shopping orientation, loyal shopping orientation, economic shopping orientation and convenient shopping orientation. Customers were segmented into following three subdivisions: shopping low-involved group, loyal leisure group and planned leisure oriented group. Third, interest age was of no relevance to clothing shopping orientation. On the other hand, look age had negative correlation with leisure shopping orientation and convenient shopping orientation and physical age had a negative relationship with leisure shopping orientation and loyal shopping orientation but had positive correlation with economic shopping orientation. Fourth, in clothing purchase, clothing purchase answerers who were younger five years than actual age had the highest frequency. It means that they purchase clothing according to subjective age perceived younger four years on average.

This study was designed to investigate the relation between mother's interaction strategies and self-regulation of young children from a Vygotskian perspective. The hypotheses of this study were: 1) The self-regulation of young children will improve with increase in age, 2) the use of mothers' interaction strategies will increase as child's age decreases, 3) mothers' directiveness in the mother-child interaction depends on the age of child and socio-economic level, and 4) mothers' directiveness in the mother-child interaction will have negative relationship with child's self-regulation. The subjects of this study were 60 mother-child dyads with three different age-of-child groups (3-, 4-, and 5-year-olds). They were further divided into higher and lower socio-economic groups. A puzzle task was used for the measurement of self-regulation. The task consisted of two identical puzzles with one used as the model. The collected data were analyzed by ${\chi}^2$, one-way and two-way analysis of variance, and Pearson's r. Self-regulation of the young children improved with increase in age (P < .05). The use of mothers' interaction strategy decreased as the children's age increased (P < .05). Mothers' directiveness in the mother-child interaction was influenced by the age of child (P < .01) and by socioeconomic level (P < .05). There was a negative correlation (r=-.848) between the mothers' directiveness in the mother-child interaction and the child's self-regulation (P < .001).

Purposes : As the population of old people has increased by the improvement of medical techniques, the concern on degenerative diseases has increased gradually. Especially the researches of osteoporosis have been carried out in view of prevention and treatment. But there wasn't any research related with Sasang Constitution. So we investigated the relation between Sasang Constitution and BMD(bone mineral density). Methods : Authors measured BMD and BMI(body mass index) of healthy women. We devided our subjects into Young age group and Old age group, and analyzed the data of Sasang Constitution subgroup. Results : 1. BMD of Taeumin was higher than those of Soyangin and Soeumin in Lumbar spine and Femoral neck in both Young and Old age group. In Old age group, there were significant differences in Taeumin vs Soeumin, and Soyangin vs Soeumin in BMD of Lumbar spine 2. BMI of Taeumin was higher than those of Soyangin and Soeumin in both Young and Old age group. In Young age group, there were significant differences in Taeumin vs Soyangin and Taeumin vs Soeumin. In Old age group, there were significant differences in Taeumin vs Soyangin, Taeumin vs Soeumin and Soyangin vs Soeumin. Conclusion : BMD and BMI of Taeumin was higher than those of Soyangin and Soeumin.

Objectives : This study was designed to evaluate the correlation of the cross-sectional areas(CSA) of paraspinalis(iliocostalis lumborum, multifidus, longissimus thoracis parts lumborum) and psoas muscle and sex, age, change of the VAS(visual analogue scale) and past history of chronic low back pain in patients suffering from HIVD(herniation of intervertebral disc). Methods : Medical records of 140 subjects with HIVD were retrospectively reviewed. The MRI(magnetic resonance imaging) findings on the patients were scanned and analyzed by PiView program to find the paraspinal and psoas muscle CSA and were evaluated by the correlation of sex, age, change of the VAS, and past history of chronic low back pain. Results : There was significant difference between groups in male and female, young-adults age and middle age, middle age and old age, young-adults age and old age. But the correlation of the paraspinal and psoas muscle CSA and past history of chronic low back pain were partially significant. On the other hand, the correlation of the paraspinal and psoas muscle CSA and change of the VAS were not significant. Conclusions : These results suggest that the cross-sectional areas(CSA) of paraspinalis and psoas muscle have relevance to sex and age.
