This study was carried out to investigate the perception, preference and usage of Korean festival foods of women according to age in Busan. The survey was conducted from October 15, 2012 to November 30, 2012 using questionnaires and the data were analyzed with the SPSS program. In general, younger women (20~30 years old) had a lower interest in Korean festival foods than slightly older women (40~50 years old). Most of women over 40 years of age prepared Korean festival foods at home, but many who were in their 20's (45.9%) and 30's (41.1%) obtained their foods from family and relatives. Overall, 62.5% of the subjects wanted to inherit Korean festival food from family and relatives. The dissemination of information and recipes of Korean festival foods were needed for succeeding to Korean festival foods. The taste score was significantly lower for women in their 20's compared to those over 40. Women under 40 reported a lower ease of cooking compared to women over 50. Tangguk (4.93) on Seollal showed the highest perception degree in the order of Namul (4.91), Tteokguk (4.90), and Sikhye (4.90). Jeon, Yaksik, Sikhye, and Gangjeong were the most highly preferred in every group. The preference degree of Pajeon was significantly higher in women under 40 than in those over 60. Tteokguk and Tangguk were more highly preferred in women in their 30's and 40's compared to the other groups. There was a significant positive correlation between preference for festival food and education level, degree of knowledge, degree of interest, will for inheritance, and will for learning (P<0.01). In conclusion, festival foods rich in local tradition should be developed, publicized and used to educate others. The simplification of cooking methods and the development of processed foods are needed to pass on the traditional food culture of Busan.

This study was conducted to investigate bone density and food behavior of middle-aged (<65-years-of-age) and oldaged women (${\geq}$65-years-of-age) in the Seoul area of Korea. Average height and weight, body mass index, body fat percentage, and waist-hip ration (WHR) of the middle-aged participants were 158.0 cm, 58.4 kg, 23.3, 29.7%, and 0.88. Corresponding measurements for old-aged participants were 152.6 cm, 56.3 kg, 24.1, 33.1%, and 0.93. T- and Z-scores for middle-aged women were -1.20 and -0.21, and those of old-aged women were -2.02 and -0.49. Osteopenia and osteoporosis percentage of middle- and old-aged women were 41.2% and 14.7%, and 45.2% and 37.1%, respectively. Significant differences were evident concerning between-meal, overeating, exercise, and nutritional supplementation among the two groups. Middle-aged women displayed a positive relationships between bone density and the parameters of height (p<0.05), weight (p<0.05), exercise (p<0.05), consumption of soybean and soybean-processed food (p<0.05), and negative relationships between bone density and the parameters of WHR (p<0.001), consumption of meat and meatprocessed food (p<0.05), and tea drinking (p<0.05). In old-aged women group, positive relationships were evident for bone density and the parameters of height (p<0.05), weight (p<0.05), exercise (p<0.05), nutritional supplementation (p<0.05), and consumption of soybean and soybean-processed food (p<0.05). The results reveal a link between healthy bones and desirable food behavior, indicating the importance of a practical and systematically organized food behavior education program for middle- and old-aged Korean women.

The present study was conducted to find out whether there are some differences in plasma carnitine levels among young-, middle-, and old-aged normal Korean women. Daily food intake, body fat content, plasma lipids and carnitine levels were measured in 153 samples from 44 young (20-24 years old), 49 middle-aged (30-49 years old), and 63 old (65-85 years old) normal volunteers. The differences in concentrations of nonesterified acylcarnitine and acid-soluble acylcarnitine were not statistically significant among them. However, acid insoluble acylcarnitine (AIAC) level in plasma decreased with age. Moreover, total carnitine (TCNE) level in the young group was significantally higher than in old and middle-aged groups. Body fat content in the young group was significantly lower than in old and middle-aged groups. Plasma total cholesterol increased with age and triglycerides in the old group were significantly higher than in young and middle-aged groups. These results suggest that the higher levels of AIAC and TCNE in the young group may be a reflection of their lipid metabolic state, which is different from middle-aged and old groups.

Osteoporosis is defined as a progressive systemic skeletal disorder characterized by low bone mineral density, microarchitectual deteriorations of bone and susceptibility to fracture. numerous methods have been used for quantitative assessment of the skeleton in osteoporosis. QCT has been shown to measure changes in trabecular mineral content in the spine with great sensitivity and precision. To provide the normal reference values and changes of lumbar spinal bone mineral density in korean adult spinal bone mineral density was evaluated in 451 women (229 premenopausal and 222 postmenopausal women) and 206 men, aged 20 to 74 years old in Wonkwang hospital from 2000 to 2004, which was carried out by using QCT. women with oophorectomy, vertebral compression fracture, any history of endocrine disease and use of drugs that alter bone metabolism were excluded. According to the WHO definition, a patient is osteoporotic based on a bone mineral density(BMD) measurement that is 2.5 standard deviations (SDs) below typical peak bone mass of young healthy white women. This measurement of standard deviation from peak mass is called the T score. BMD values of normal women in their 20-24 years, 25-29 years, 30-34 years, 35-39 years, 40-44 years, 45-49 years, 50-54 years, 55-59 years, 60-64 years, 65-69 years, over 70 years were 168.95㎎/㏄ K₂PHO₄, 155.41㎎/㏄ K₂PHO₄, 166.87㎎/㏄ K₂PHO₄, 160.67㎎/㏄ K₂PHO₄, 154.06㎎/㏄ K₂PHO₄, 132.04㎎/㏄ K₂PHO₄, 114.05㎎/㏄ K₂PHO₄, 91.78㎎/㏄ K₂PHO₄, 78.61 ㎎/㏄ K₂PHO₄, 61.35㎎/㏄ K₂PHO₄, 50.53㎎/㏄ K₂PHO₄ Mean bone density of normal women was 115.77K₂PHO₄ K₂PHO₄. BMD values of normal men in their 20-24 years, 25-29 years, 30-34 years, 35-39 years, 40-44 years, 45-49 years, 50-54 years, 55-59 years, 60-64 years, 65-69 years, over 70 years were 171.46㎎/㏄ K₂PHO₄, 162.19㎎/㏄ K₂PHO₄, 155.62㎎/㏄ K₂PHO₄, 147.28㎎/㏄ K₂PHO₄, 137.56㎎/㏄ K₂PHO₄, 137.56㎎/㏄ K₂PHO₄, 101.25㎎/㏄ K₂PHO₄, 109.00㎎/㏄ K₂PHO₄, 103.32㎎/㏄ K₂PHO₄, 91.53㎎/㏄ K₂PHO₄, 88.35㎎/㏄ K₂PHO₄ Mean density of normal men was 115.77㎎/㏄ K₂PHO₄. Peak bone density of women and men was in the age group of 20-24 years and 168.95㎎/㏄ K₂PHO₄, 171.46㎎/㏄ K₂PHO₄, respectively. Bone loss was increased with aging and was accelerated in postmenopausal women than that of premenopausal women. The total loss of BMD for women and men was 70.09% and 48.47%, respectively. Postmenopausal women(mean BMD : 85.83㎎/㏄ K₂PHO₄) had significantly lower BMD than premenopausal women(meand BMD : 144.80㎎/㏄ K₂PHO₄)(p<0.001). The annual loss of BMD of women and men was 2.702㎎/㏄ K₂PHO₄ and 1.795㎎/㏄ K₂PHO₄, respectively. This study provided the BMD reference data for normal korean adult. further studies on BMD in healthy adult and comparison with published data are needed.

The purpose of this study was to estimate coffee consumption and it's relationship to blood pressure and blood lipid profiles in Korean adult men and women. Antheropometrics, dietary intake by 24-hour recall, and serum lipid profiles were measured in 354 subjects. The average subject ages for the age ranges of $20{\sim}49$, $50{\sim}64$, and over 65 years, were 39.7, 57.5, and 70.6 years for the men, and 40.7, 56.9, and 70.9 years for the women, respectively. Mean height and weight were significantly higher in the men and decreased with increasing of age. Thirty percent and 28% of the men and women, respectively, consumed coffee. The proportions of coffee consuming subjects in the age rangers of $20{\sim}49$ years(34.9%) and $50{\sim}64$ years(35.6%) were significantly higher than in the group over 65 years(11.5%). The mean daily intakes of food and energy were showed the same results according to sex and age. Mean daily coffee intake was not significantly different between the men and women, but it was significantly lower in the over 65 age group. Systolic blood pressure was significantly higher in the men and increasing age. The atherogenic index was significantly higher in the $20{\sim}49$ year-old men, and in the women over 65 years. There were no significant correlations among coffee consumption, blood pressure, and the serum lipid profile. In conclusion, the daily coffee consumption by adult men and women, with the exception of the elderly, was $50{\sim}90m{\ell}$, and it was not significantly correlated to blood pressure or blood lipids.

This study investigates the yoga clothing market for women over 50 years old. The study found that the target demographic felt that many brands were participating in the Yoga Wear market, but most targeted 20-30 year old women. They felt it was difficult to find brands for women over 50 years old. One common complaint by the target demographic was that they experienced discomfort when wearing Yoga Wear currently available in the market. They attributed this to the fact that even the largest sizes available were not appropriate for their body size. They also noted that there is a large variety of designs presently available in the market; however, most are too colorful and revealing for their tastes. Females in their 50s or older preferred less colorful and less revealing clothes. They noted that they reacted sensitively to fat in the forearms due to changes in body shape as they grew older and wanted looser clothes. Elasticity and hygroscopicity of material are therefore very important buying criteria for the target demographic. These criteria were used to propose a prototype yoga suit designed for women over 50 years old.

There are numerous reports on menarche age in korea and other countries but only few reports are available on menopausal age. This is a result of surveys on 509 women for menarche and 341 women for manopause among the rural areas of Choongnam and Kyungbuk province. For those born between 1894 and 1929. aver age ageof menarche was 16.63 years. The earliest was 13 years and latest was 22 years old. Majority (78.8%) had their menarohe at the age of between 15 and 18. It was noted that there was gradual advancement of menarche age among those born in later years than earlier. More menarche started in the months of October and April and fewest was in the month of June. Spring was the time when the largest number of women had menarche and this was followed by Autumn. Winter, and Summer. The most common menstrual cycle was 39 days type which is followed by 28 days and 26 days. The average monpausal age among rural korean women was 46.97 years. The number of years between menarche and menopause appears to be dependent upon individual physical and mental condition. socioeconomical circumstances. and also hereditary as well as ethnic differences. 87.1 % of rural korean women had menstrual ages of between 20 to 35 years according to this statistics and the average was 29.67 years.
