Purpose: The purpose of this study was to compare the practice of quarantine guidelines and psychological influence between the young (aged under 64 years) and the elderly (aged over 65 years) groups during the coronavirus disease 19 (COVID-19) pandemic. Method: The data of this study were obtained from the Community Health Survey, 2020, Korean Disease Control and Prevention Agency. A total of 229,296 (young group: 156,314, elderly group: 72,812) participants were included in this study. Independent t-test, chi-square test and descriptive analysis were used for analyzing the data. Result: Elderly group showed lower adherence to wearing face-mask, maintaining social distance when outgoing and practicing handwashing rules than the young group. The elderly group showed a higher level of psychological influence than the young group. In addition, the elderly group had fewer supporters when they were isolated than the young group. Also, the elderly had difficulties in following the quarantine guidelines related to COVID-19. Conclusion: To prevent infection and death from COVID-19 in the elderly, proper education and support programs are needed. Also, support groups should be prepared and applied to relieve their psychological impact related to COVID-19.

This study investigated perceived discomforts and those reasons of the young and middle-aged, the aged, the disabled and the pregnant in various daily activities, and elicited universal design factors based on human capacities (physical, sensory, cognitive and affective). A total of eighty people (twenty subjects for each user group) participated in one-to-one interviews about thirty six items of daily activities. A degree of discomfort of the daily activities was measured using Borg's CR10 scale. As a result, the disabled and the pregnant complained about almost all of the daily activities, and their degrees of discomforts were significantly higher than those of the youth and middle-aged and the aged. However, the youth and middle-aged and the aged only complained about some specific items. The major reasons of discomforts were related to physical and affective capabilities in general, where the detailed reasons of each user group were comparatively different. Finally, the universal design factors were elicited for each daily activity item based on the results of each user group. This study can be used to understand the discomforts and characteristics of the aged, the disabled and the pregnant in the various daily activities. The universal design factors elicited can also be applied to design related products and facilities universally.

Inflammaging in male reproductive organs covers a wide variety of problems, including sexual dysfunction and infertility. In this study, the beneficial effects of cordycepin (COR), isolated from potential medicinal fungi Cordyceps militaris, in aging-associated testicular inflammation and serum biochemical changes in naturally aged rats were investigated. Male Sprague Dawley rats were divided into young control (YC), aged control (AC), and COR (5, 10, and 20 mg/kg) treated aged rat groups. Aging-associated serum biochemical changes and inflammatory parameters were analyzed by biochemical assay kits, Western blotting, and real-time RT-PCR. Results showed a significant (p < 0.05) alteration in the total blood cell count, lipid metabolism, and liver functional parameters in AC group when compared with YC group. However, COR-treated aged rats ameliorated the altered biochemical parameters significantly (p < 0.05 and p < 0.01 at 5, 10, and 20 mg/kg, respectively). Furthermore, the increase in the expression of inflammatory mediators (COX-2, interleukin (IL)-6, IL-1β, and tissue necrosis factor-alpha) in aged rat testis was significant (p < 0.05) when compared with YC group. Treatment with COR at 20 mg/kg to aged rats attenuated the increased expression of inflammatory mediators significantly (p < 0.05). Mechanistic studies revealed that the potential attenuating effects exhibited by COR in aged rats was mediated by regulation of NF-κB activation and MAPKs (c-Jun N-terminal kinase, extracellular signal-regulated kinase 1/2, and p38) signaling. In conclusion, COR restored the altered serum biochemical parameters in aged rats and ameliorated the aging-associated testicular inflammation proving the therapeutic benefits of COR targeting inflammaging-associated male sexual dysfunctions.

This study examined the effect of calcium supplementation and exercise on bone mineral density (BMD) and general characteristics, dietary intake and biochemical measurements for 45 healthy middle-aged women (40-57 years). Subjects were divided in to 4 groups; control group (G1), exercise group (G2), calcium supplementation group (G3), and calcium supplementation with exercise group (G4). The subjects were 45.8$\pm$ 0.66 years old. BMI(kg/$m^2$) was 23.31 $\pm$ 0.63 in Gl group, 22.92 $\pm$ 0.51 in G2 group, 23.64 $\pm$ 0.61 in G3 group, 23.40 $\pm$ 0.37 in G4 group, and BMI of all groups were in normal value. Energy intake was 1332.28㎉/day, 60% of RDA, so that may be unbalance of micronutrients. Especially, calcium intake was 62.8% of RDA that was very low level. Osteocalcine was not statistically significant but calcium supplementation group (G3) be showed increase. BMD was usually decreased by Aging, but in this study was increased in the all group, except control group. It showed increase of BMD for calcium supplementation and/or exercise. Overall results indicate that calcium supplementation and/or exercise increased BMD of middle-aged women, but long-term calcium supplementation and exercise will be able to more effect.(Korean J Nutrition 35(9) : 962~969, 2002)

For the purpose of providing basic data for the development of size specifications for middle-aged women in Busan, one dimensional measurements were made with the subjects. ranging 45 to 59 in age. The following are the conclusions : 1) According to ages, the middle and elder groups of the middle-aged women shared similar body types, having shorter height, more lowered bust. and increased upper-body depth and girth factors, compared with the earlier middle-aged women group. But the thigh girth of the elder middle-aged group (age: 55∼59) was the lowest, maybe owing to the aged lower-body muscles. 2) In the comparison with national averages. armhole girth, elbow girth, wrist girth. back waist length, side neck point-B.P.-waist line, and sleeve length showed great differences. This is problematic in that the national size standards fail to reflect each legion\`s peculiar body type characteristics. 3) Even though body types were classified according to drop value criteria suggested by KS specifications, 23.05% did not belong to the criteria. They were thus classified as A, N, and H body types, following the distribution of the present experiment. 4) In consideration of the economy factor of the production and sales of the clothes industry, the combinations of height and chest garth for the middle-aged Busan women were as follows: 155cm-85cm (Body Type A) 150cm-88cm (Body Type N), and 155cm-94cm (Body Type H).

The purpose of this study was to develop health promotion programs for middle aged women and to identify the adaptability and the effectiveness of the program in order to provide a model for health promotion programs as a basis for nursing intervention. The research design was a quasi-experimental, nonequivalent control-group pretest -posttest design. The data were collected from October 30 to December 11, 1996. The study subjects were middle aged women residing in Chonju city, with ages from 40 to 59. The experimental group consisted of 42 subjects who were recruited through announcements of the local newspaper. The control group consisted of 49 subjects who were mothers of nursing college students. The health promotion program for middle aged women was based on the Bandura's self efficacy theory and Pender's heath promotion behavior theory consisting of exercise and heath diaries as performance accomplishments as well as education and group sessions as verbal persuasion and vicarious experiences. The study program was provided for 6 weeks, 3 hours a day per week. There was a pretest before the program and a posttest after the 6 week program. The instruments used for the study were a Self Efficacy Scale and a Health Promotion Behavior Scale developed by Park(1995). The data analysis was done by the use of a SPSS/PC. The study results were as follows: 1. In the analysis of the homogeneity between the experimental and control groups, there were significant differences in the socio-demographic characteristics, self efficacy and health promotion behavior. There were significant differences between the experimental and control groups in occupation, the number of children, and the status of involvement in social activities. 2. The first hypothesis, 'The level of self efficacy of the experimental group will be higher than that of the control group.' was supported(F=10.154, p=.002). The second hypothesis, 'The degree of health promotive behaviors in the experimental group will be higher than that of the control group.' was supported(F=17.349, p=.000). 3. There was a significant positive correlation between the self efficacy and the health promotion behaviors in pretest and posttests (pretest: r=.732, p=.000 ; posttest : r=.754, p=.000). 4. The significant variables for health promotion behaviors were religion(t= -1.97, p=.05), family income(F=4.85, p=.00), education level (F=6.38, p=.00) and involvement in social activities(t= -3.06, p=.00) in socio-demographic characteristics. In summary, a heath promotion program based on self efficacy theory has made an improvement on health promotion behaviors. Also, the results show that the higher the level of self efficacy, the better the health promotion is in middle aged women. The study has proved that nurses can provide nursing intervention for the improvement of health promotion in middle aged women through the adaptation of a program increasing the subject's self efficacy level.

Objective: The objective of this study was to evaluate the physicochemical, sensory and taste characteristics of commercial, frozen, dry, and wet aged Hanwoo sirloin. Methods: Grade 2 sirloin from 6 Hanwoo steers (about 30 months old) were obtained after 5 days postmortem. Samples were assigned to four groups which were commercial beef (CON, control group), frozen beef (Hanwoo frozen, HF; 40 days in $-18^{\circ}C$ freezer), wet-aged beef (Hanwoo wet-aging, HW; 21 days), and dry-aged beef (Hanwoo dry-aging, HD; 40 days). HW and HD were stored in a $80%{\pm}5%$ relative humidity cooler at $1^{\circ}C$. Results: The HF group showed a significantly higher cooking loss and expressible drip with significantly higher pH compared to other groups. In addition, protein and fat contents in the HD group were higher than those in other groups (p<0.05). The shear forces in the HW and HD groups were significantly lower than those in the CON group. The HD group had significantly higher omega-3 and polyunsaturated fatty acids compared with other groups. Glutamic acid levels in the HD group were significantly higher compared with those in other groups. Electronic tongue analysis revealed that sourness of the HD group was lower than that of other groups, whereas the HD group showed significantly higher umami, richness, and saltiness compared to other groups (p<0.05). Sensory test results revealed that the HW group had significantly higher tenderness, while the HD group had significantly higher chewiness, juiciness, and overall acceptability scores. Conclusion: These results suggest that both wet- and dry-aging treatments can effectively improve sensory characteristics, and dry-aging was much more useful to enhance umami tastes and meat quality of 2 grade Hanwoo sirloins.
