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.

The author performed on epidemiological study of the TMD in 189 elderly people and 195 young people with Helkimo index. The clinical dysfunction index was based on data from clinical examination and the anamestic dysfunction index was based on data from the interview with the investigated person. The results were as follows : 1. In the elderly population, 27.5% reported that they had subjectively symptom of TMD but 43.4% had sign and symptoms of TMD in clinical examination. 2. The mean values for maximal opening differed significantly between elderly and young populations, 47.22mm and 51.44mm (p<0.001) and less than a 40mm opening was observed 7.9% in elderly population, 0.5% in young population (p<0.001). 3. The mean values for lateral movement to the right and left did not differ with age, which were 8.56mm and 8.47mm in elderly population, 8.90mm and 8.81mm in young population, but the mean value for protrusion differed significantly between elderly and young populations, 6.89mm and 7.64mm (p<0.01). 4. A higher incidence of TMJ noise was recorded in the elderly and young populations than young population, especially crepitus, but a higher incidence of clicking was recorded in young population (p<0.05).

This study was undertaken to compare the gait characteristics between the Korean elderly and young adults, we measured the plantar pressure and contact time of gait with barefoot along a walkway at their preferred walking speed. The results indicate that older people exhibited significantly less plantar pressure than young adult in all 3 regions (FF, MF and RF) and significantly less time % on the initial contact phase (ICP), forefoot push-off phase (FFPOP) and significantly more % forefoot contact phase (FFCP) and foot flat phase (FFP). The converted plantar pressure value to percentage, it showed more pressure in forefoot (FF) in the elderly person than the young adults. It could be explained that the forward shifting in plantar pressure are associated with a more flexed posture of elderly such as actual stabilizing fearrelated adaptations. Longer total foot contact time in the elderly means that the old people show the decreased gait velocity. In other words, lower velocity was found to be associated with pre-existing fear of falling. With longer contact time and slower stepping movement, the elderly become more unstable. With these findings, it could be confirmed that there were significant changes in foot characteristics which contribute to alter the plantar pressure and contact time during gait with advancing age. Further research is required to establish possible links to risk of falling and development of footwear in the elderly adults.

Objective: The purpose of this study was to compare the physical characteristics (bone mineral density, joint muscle strength) and running biomechanics between older adults and young adult runners to understand the changes of running strategy by aging. Method: Bone mineral density (Dual Energy X-ray Absorptiometry, USA) of lower lower extremity and muscle strength (Cybex Humac Norm [DEXA], CSMI, USA) were measured to identify the physical characteristics of 10 elderly (age: $67.70{\pm}3.30yrs$, height: $1.68{\pm}0.04m$, mass: $67.70{\pm}3.80kg$) and 10 young adults (age: $21.20{\pm}0.42yrs$, height: $1.73{\pm}0.06m$, mass: $72.11{\pm}4.15kg$). Running data was collected by using an instrumented treadmill (Bertec, USA) and 7 infrared cameras (Oqus 300, Qualisys, Sweden). Two-way repeated ANOVA analysis was used to analyze results at a significant level of .05 with Bonferroni post hoc analysis. Results: Compared to the young adult group, the elderly group showed statistically significant difference in physical characteristics and in running characteristics. Elderly runners showed lower BMD and muscle strength compared with young runners (p<.05). In the running parameters, elderly runners tend to show shorter contact time and stride length compared with young runners (p<.05). In the joint angles, elderly runners showed smaller range of ankle motion compared with young runners (p<.05). Finally, elderly runners showed lower level of joint moment, joint power, and GRF compared with young runners in each running speed (p<.05). Conclusion: The running behavior of the elderly performed periodic running was similar to many variables of young adults. However, there were noticeable differences found in the ankle joints and most kinetic variables compared with young adult runners. This discrepancy may propose that elderly runners should consider appropriate running distance and intensity in the program.

The purpose of this study Is to classify foot types of elderly women and young women and to suggest shoes size system by foot types for elderly women. The subjects were 321 elderly women and 181 young women. Their right feet were measured directly and indirectly by using scanner and digital camera. The anthropometric measurements were composed of 62 items. They were measured during the months of July and October in 2001 and November in 2002 The results and discussions of this study are as follows. First, in analyzing shape of the foot of elderly and young women, the shapes of foot were classified as N-type (high and narrow foot shape and wide toes), W-type (wider width for its length and severe alteration), L-type (low foot shape as oval). Second, the most characteristic foot type in elderly women was W-type. In this type, the width was wider for its length, the first metatarsophalangeal protrusion was severe and the toes were gathered at the center. On the other hand, young women belonged to N-type. Third, we suggested new size system of shoes for elderly women and the standard foot shape each type. The size system was based on foot length and foot types. Hopefully, understanding the shapes of foot and characteristics of each foot type will help to develop suitable shoes for elderly women.

In this paper, we investigated the maximum ankle joint plantarflexion moment(MPM) of young and elderly subjects during various modes of isokinetic contractions with special interest in the elderly females who were reported to have higher fall rate than the elderly males. Subjects include the young subjects(14 males: $22.7{\pm}2.5yrs$, 13 females: $20.5{\pm}1.3yrs$) and the elderly subjects(17 males: $65.8{\pm}10.5yrs$, 26 females: $71.4{\pm}5.2yrs$). The MPM was normalized by each subject's body weight. The MPM of elderly females was the weakest among the groups, particularly, at the eccentric contractions. The male-to-female ratio of MPM was greater in the elderly than in the young and the young-to-elderly ratio of MPM was greater in female than in male, both during the eccentric contractions. The result suggests that the decreased muscle force per body weight, especially at the eccentric contraction, may be one reason for the more frequent fall of the elderly female than the elderly male.

This study aimed to analyze the preliminary data to increase the residents' satisfaction of mixed-generation house-sharing. For this purpose, we examined the recognition and demands of different generations and compared the differences. The participants were 50 elderly and 100 young people living in Seoul. The data were analyzed using SPSS statistics. The key findings are outlined below; 1. Most of the young people in our sample got to know about the house-sharing via various routes, but this option was not well known to the elderly. The interest in living in a house-sharing situation was higher among the young people than among the elderly. The reason why people were uninterested in house-sharing was their comfort in living alone. 2. Secure personal-space privacy and the choice of a housemate were regarded as the most important considerations in house-sharing by the young and the elderly, respectively. Young people anticipated a division of housework and the elderly were worried about communication with the younger generation. 3. Expected benefits tended to be higher in economic aspects for the young and in psychological aspects for the elderly. The elderly responded that they would be willing to share the kitchen and living room with the younger generation. Young people demanded necessary living facilities such as a laundry room and a community area with the elderly. The majority of the respondents from both generations said they would be able to solve problems through communication. In conclusion, public relations are needed to increase interest in house-sharing. The elderly and young should understand its purpose and treat each other as family members, not as house owners and tenants. There should be a manager who can coordinate the residents.

Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

Purpose: The study compared the rest-activity rhythm and sleep pattern of elderly with young group. Methods: The subjects were 22 over than 65 years old and 23 under 65 years old. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for this study. The data were analyzed with $x^2$, Lamda test, t-test and correlation with SPSS 15.0 program. Results: The elderly had lower curve than the young group in rest-activity rhythm on each time zone. In particular, the elderly group had lower rest-activity rhythm curve of 8, 9, 14, 18, 19, 20, 21, 22 and 23 time zone than those of young group. Sleep pattern had statistical difference in the total sleep time, PSQI and insomnia. Total sleep time of elderly had lower score and PSQI and Insomnia had higher score than young group. Age had correlation with rest-activity rhythm, sleep efficiency, PSQI and insomnia. Conclusion: Rest-activity rhythm of the elderly showed an increase in activity in the early morning because of earlier get up than the young group and an decrease in activity in the afternoon because of taking a nap at this time. Elderly sleep was that total sleep time increased but sleep efficiency decreased and insomnia intensified. This sleep pattern was related to age and rest-activity rhythm.
