This study was carried out to compare the bone mineral density and risk factors of osteoporosis between normal and rheumatoid arthritis in postmenopausal women. Sixty-eight postmenopausal patients with rheumatoid arthritis(RA) were compared with 124 postmenopausal normal women. Data were collected from october, 1998 to April, 1999 at Dong-a university hospital in Pusan. From all subjects, individual characteristics such as age, body weight, height, age of menarche, duration of menopause, gravity, parity, and breast feeding period and factors of life style such as milk consumption, exercise, alcohol intake, cigarette smoking, coffee consumption were identified as influencing factors of osteoporosis by questionnaire. From RA patients, health assessment score, Ritchie articular index, erythrocyte sedimentation rate, C-reactive protein and steroid dosage were measured by rheumatologist on measuring bone mineral density. Bone mineral density was measured at the Lumbar spine, femoral neck, femur Ward's triangle, and femur trochanter using dual x-ray absorptiometry. The data was analyzed by using a frequency, t-test, Chi-square, ANCOVA with SPSS PC program. The results could be summarized as follows : 1) There was a significant difference in age and breast feeding period between RA patients and normal women. 2) RA patients took less calcium in the past and practiced less regular exercise in past and present than normal women. 3) There was no difference in lumbar bone mineral density between RA patients and normal women. 4) There was a significant difference in femur Ward's triangle and femur trochanter between RA patients and normal women after adjustment for age and breast feeding period. 5) The prevalence of osteoporosis of all subjects was the highest in femur Ward's triangle. In summary, our findings suggest that the bone mineral densities of femur Ward's triangle and trochanter in postmenopausal women with RA is significantly lower than normal women. Also the exercise participation rate of postmenopausal women with RA is lower than normal women. For the further study, we recommend to develop exercise program that improve the bone mineral density in femur Ward's triangle and trochanter and to test the effect of that exercise program.

The aim of this study was to investigate intake of health foods and supplements and its associated factors in middle and old-aged adults in order to contribute to health promotion of Korean population by providing a guide for proper use of health foods and supplements. About 69% of the subjects reported that they were currently taking health foods and supplements or had experiences of having them in the past, whereas 31.2 % reported they had never taken them. The most commonly used type of health foods and supplements was vitamin C as reported by 41.8% followed by others such as lactobacillus products, multi-vitamins, tonic medicine and cardiotonic drug, artificially processed Ginseng foods, vitamin B complex, enzyme supplement, calcium, aloe, apricot extract products, chitosan products, loyal honey, squalene, refined fish oil and iron products. The major reason for taking health foods and supplements was 'to protect the weak constitution' with 155 (42.1%) responses, and the motive for the intake was the suggestion from family-relatives with 235 (63.9%) responses, and the place of purchase was pharmacy with 140 (38.0%) responses, the average monthly expense was 20,000-40,000 won with 140 (26.2%) responses, and effects after the intake was 'so and so' with 180 (33.6%) responses as the highest. More health foods and supplements were consumed as age and education were statistically significantly increased (p<0.05). For health and lifestyle and the intake of health foods and supplements, perceived health status, the presence of illness, and the presence of health management were statistically significant (p<0.05). Male subjects than female subjects and the 30s than the 405 and 50s were appeared to have poorer dietary behaviors (p<0.05). For the health locus of control and the intake of health foods and supplements, the health locus of control score was 22.82 for consumers and 22.79 for non-consumers, showing no significant difference. Logistic regression analysis was performed to find out major factors that affect the intake of health foods and supplements, in which gender, education, smoking, perceived health status, the presence of illness, and health management were significant to the intake of health foods and supplements. It is shown that subjects with perception and attitude of 'health foods and supplements are useful in health maintenance and disease prevention' and 'the information and variety for health foods and supplements are great' have higher probability of taking health foods and supplements.

The purpose of this study was to evaluate the eating behaviors and dietary quality of various aged adults. This study conducted through questionnaire and dietary survey by 24-hr recall to 850 adults residing in Samcheok. Subjects were divided into four groups according to the age in male and female, which included 20~29 yrs group (male n = 94, female n = 66), 30~49 yrs group (male n = 201, female n = 216), 50~64 yrs group (male n = 88, female n = 96), and $\geq65$ yrs group (n = 46, female n = 43). In male, 20~29 yrs group had a larger proportion of subjects who skipped breakfast, lunch and dinner compared to other groups (p < 0.001, p < 0.05, p < 0.01). The daily food and energy intakes in $\geq50$ yrs group were significantly lower than those of < 50 yrs. Protein and fat intakes of 20~29 yrs group were significantly higher than those of the other groups. But ND (Nutrient Density) of minerals as like calcium, iron and plant iron in 20~29 yrs group were significantly lower than those of other groups. The KDDS (Korean's Dietary Diversity Score) of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in male were 4.1, 3.8, 3.7 and 3.5 respectively and there was significant difference (p < 0.001). In female, skipping breakfast and dinner were significantly higher in 20~29 yrs group than in other groups (p < 0.001, p < 0.001). And the use of nutrient supplementation was higher in 30~49 yrs group than that of other groups (p < 0.05). The daily energy intakes was higher in 20~49 yrs group than that of $\geq65$ yrs group. The ND (Nutrient Density) of animal protein, vitamins A and $B_1$ in 20~29 yrs group were significantly lower than those of other groups. The KDDS of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in female were 4.0, 3.9, 3.9 and 3.6 respectively and $\geq65$ yrs group was significant lower than other groups. According to these results, $\geq65$ yrs and 20~29 yrs group had more dietary habit problems and poor nutrition status than 30~64 yrs group. The results of this study revealed that nutritional management and education for adequate meals should be emphasized in adults and elderly.

This study was conducted to prepare canned salmon frame and to characterize its food components. In the preparation of high-quality canned foods, the boiling water generated in the pre-heating process should be removed, and then the pre-treated canned salmon frame should be sterilized for an $F_0$ value of 12 min. The proximate composition of the canned salmon frame prepared under optimal conditions (CSFP) was 58.4% moisture, 15.7% protein, 21.4% lipid, and 3.5% ash. Based on the results of volatile basic nitrogen and microbiological tests, the CSFP was acceptable. The sensory score for the color of CSFP was 4.1 points, which was higher than that of commercial canned salmon frame (CCSF). However, there were no significant differences in the sensory scores for flavor and taste between CSFP and CCSF. The total amino acid content of CSFP was 14.58 g/100 g, which was 4.9% lower than that of CCSF. The major amino acids in CSFP were aspartic acid (11.0%), glutamic acid (14.8%), and lysine (10.6%), which accounted for 36.4% of the total amino acid content. The CSFP was high in calcium and phosphorus, while it was low in magnesium and zinc. The major fatty acids in CSFP were 16:0 (15.2%), 18:1n-9 (17.0%), 18:2n-6 (16.7%), 20:5n-3 (9.3%), and 22:6n-3 (8.8%). Based on the results, CSFP is a high-quality canned food in terms of hygiene and nutrition.

In this study, inorganic elemental distribution in Korean adult human tissue of liver, lung, muscle, kidney, rib and thyroid has been investigated. These tissues were collected from human's body within 48 hours after their death according to IAEA's recommended method, dried by freeze drying method and then pulverized. Neutron activation analysis was applied to these samples to determine the concentrations of 5 major elements of Ca, Mg, Na, K, and Cl and 12 trace elements of Mn, I, Sr, As, Br, Co, Cr, Cs, Fe, Rb, Se, and Zn. To confirm accuracy of analytical result was performed using three kinds of standard reference materials and resulted that the relative error is within 10% for the most of elements and the Z-score indicating a performance of analysis is within 2. The elemental distribution shows that the major elements are distributed homogeneously with a specific concentration and that the trace elements shows a distribution of different concentration with kinds of tissue and their age. Particularly, iodine shows higher concentration with 1000 ${\mu}g/g$ in thyroid, and calcium and strontium show the concentration with 15.9% and 84.4 ${\mu}g/g$ in rib, respectively.

This study was conducted to examine food and nutrient intakes of weekday and weekend with 329 high school boys residing in Seoul using the 3-day food record. Frequency for breakfast skipping was the highest as compared with lunch and dinner skipping. Frequencies for breakfast and lunch skipping were significantly higher in weekend than weekday (p<0.05). The daily average food, vegetable food and animal food intakes were 1,327.6 g, 800.5 g, and 425.8 g, respectively. Total food and vegetable food intakes of weekday were significantly higher than weekend(p<0.05). The dietary variety score(DVS) was 20.5 in daily average, 23.3 in weekday and 15.1 in weekend, which showed significantly higher in weekday than weekend(p<0.05). The daily averages of energy, protein, fat and carbohydrate intake were 2244.9 kcal, 89 g, 72.6 g, and 311.2 g, respectively. Fat intake was significantly lower and carbohydrate, fiber, phosphate, iron, sodium, potassium, vitamin A, niacin, folate, and vitamin C intakes were significantly higher in weekday than weekend (p<0.05). The percentages of energy intake from carbohydrate, protein, and fat were 55.4%, 15.8%, 28.8% in daily average, 56.8%, 15.8%, 27.4% in weekday and 53.6%, 15.8%, 30.7% in weekend, respectively. The percentages of energy intake from carbohydrate in weekday and weekend were below 60%, and that from fat was above 27% in weekday and weekend. Carbohydrate intake was significantly higher and fat intake was significantly lower in weekday than weekend(p<0.05). Energy intakes of daily average, weekday and weekend were above 83% as compared with estimated energy requirement(EER). Intakes of dietary fiber, calcium, potassium, vitamin C, riboflavin and folate were below 75% as compared with adequate intake(AI) or recommended intake(RI). Mean adequacy ratios(MAR), an index of overall dietary quality were 0.78 in daily average, 0.80 in weekday and 0.75 in weekend. MAR of weekend showed significantly lower than weekday(p<0.05). This study revealed that the overall nutrient intake status was worse in weekend than weekday among high school boys.

Objectives: The aim of this study was to compare the nutritional intake and Diet Quality Index-International (DQI-I) of gynecological cancer survivors and normal women. Methods: This study compared the anthropometric indices, dietary behavior, nutritional intake, and DQI-I in women with previous history of breast or uterine cancer [Gynecological cancer survivors group (GCSG, n=126)] and normal women [Normal control group (NCG, n=7,011)] using the 2013~2016 Korea National Health and Nutrition Examination Survey data. Results: Body mass index and waist circumference were lower in the GCSG compared the NCG. The frequency of skipping breakfast and eating out was higher in the NCG compared to GCSG. Energy and fat intake were significantly higher in the NCG than in the GCSG, whereas intake of all minerals and vitamins (excluding thiamine), and dietary fiber intake were higher in GCSG. It was observed that the fatty acid intake of the GCSG was significantly lower than that of the NCG. The diet quality evaluation using DQI-I results showed that GCSG was higher in the "within-group" diet variety and adequacy of vegetable group than the NCG, whereas the intake level of the fruit group was higher in NCG. Besides, protein, calcium, and vitamin C intake were higher in the GCSG than in the NCG. The GCSG showed higher levels of total fat and saturated fat moderation than the NCG, whereas cholesterol moderation showed the opposite results. The results of DQI-I comparison according to the cancer survival years showed that the overall score and scores related to diet adequacy and balance were higher in the below 5-year group, whereas the over 5-year group scored higher in terms of moderation of diet. Conclusions: The results of this study suggest that a chronic disease based management approach is needed in cancer survivors. The study provides important data which can help in the preparation of guidelines for long-term lifestyle and diet management, in these patients.

Disease, such as osteopenia, osteoporosis, etc caused by reduced bone density are common to women after menopause and as the social medical cost increases due to osteoporosis fractures the medical interest in bone density reduction has increased. The bone density reduction is observed even for renal failure patients, due to their decreased ability to synthesize vitamin D which leads to bone fibrosis because of deficiency in calcium absorption. Thus renal failure patients not only suffer from kidney dysfunction, but also are exposed to complications, such as osteoporosis, due to reduced bone density. This research observed the change in bone density of patients receiving renal failure treatment and analyzed the change in bone density before and after kidney transplantations. Subjects were 214 renal failure patients at the department of nephrology Busan B General Hospital. The change in bone density was studied for subjects with and without kidney transplantation according to their age and sex. The research showed improvement or maintenance of bone density for subjects that received kidney transplantation, but showed a tendency of consistent decrease in bone density for subjects without kidney transplantation. Kidney transplantation can be considered as the best cure for renal failure patients, and this researched confirmed that bone density can be improved through kidney transplantation. Thus, this study can also be used as data for preventing complications due to renal failures.

The change of pectinesterase (PE) activity and pectin substances in fig fruit were investigated and low sugar jams prepared by various methods from fig fruit were compared. Fig fruit PE, which began to show the activity at the harvest time, was not inactivated and had slight activity during frozen storage at $-25^{\circ}C$. The amount of alcohol insoluble solid (AIS) and the degree of esterification (DE) of AIS were reduced by its own PE activity. However the intrinsic PE of fig fruit was not enough to make low-methoxyl pectin below 50% of DE. Fig pulp treated by its own PE and combination of fig PE and orange PE could make low-methoxyl pectin. After PE treatments, fig pulp adjusted below pH 4.0 by addition of citric acid kept red colour. Fig Jams processed by various methods had lower soluble solid $(31{\sim}49^{\circ}Brix)$ compared with conventional fig jam. Five kinds of fig jams out of those showed higher score than others in the sensory evaluation. For preparation of the five jams, the fig pulps with or without 1% pectin were treated at $50^{\circ}C$ for 25 minutes with addition of orange PE (200 units/400 g pulp). The treated pulps were added with 0.25% citric acid, 0.7% calcium and 20% cane sugar. The mixed pulps were prepared for jams containing low sugar by hot plate or microwave or refrigeration (excepting the mixed pulp without pectin).

This study was designed to examined psychosocial status and nutritional factors(nutrition knowledge, dietary attitudes, eating behavior, dietary intakes) among female university students and to investigate if there were differences in these variables by weight loss attempt. A cross-sectional survey was conducted to 225 female university students in Seoul. Survey instrument was adapted or modified based on literature review, and dietary intakes were assessed using 24-hour recall and CAN-pro. Descriptive statistics, t-test x$^2$-test were used in data analysis. Mean height, weight of subjects were 162.7cm, 51.3kg, and mean BMI was 19.4. One hundred-nine students(48.4%) were grouped into weight loss attempt roup and 116 students were grouped int non-attempt group. According to BMI, 58.7% of weight loss attempt group were underweight, suggesting that unnecessary weight control is common in college women. With respect to psychosocial status, subjects received moderate degree of stress and were slightly satisfied with life. There was no significant difference in stress, social support or self-esteem between the two groups, however, students in non-attempt group were more satisfied with their life(p<0.01) and adapted better in school that students in weight loss attempt group. Subjects scored 14.9${\pm}$2.1 (highest score : 20) on nutritional knowledge, and showed favorable dietary attitudes. Overall, nutritional knowledge and dietary attitudes were not significantly different between the two groups. Common eating problems were irregular meals(71.6%), followed by unbalanced meals and eating-out. Subjects in weight loss attempt group were more likely to change eating habit after entering the university and showed more undesirable eating habit. Dietary intake data indicated hat the energy derived from fat was slightly higher than the recommended level. Most of the nutrient intake was lower than the RDA, particularly, iron and calcium intake was below the 50% of the RDA. Although this study did not reveal significant difference in nutritional knowledge or dietary intake by weight loss attempt, this study showed status of weight control, eating habit and dietary intake in female university students, and provide some information for nutrition education of college women.
