The Homeshare Program was promoted to solve the housing problems of the elderly and the young by the Seoul City in 2012. The elderly can provide spare rooms in their homes for the young at low rental fees, and the young can provide daily services to the elderly, cooperating with each other for better housing and life. The aim of this research is to find out how the participants use the shared space and what kinds of activities are shared in homeshare. This research uses case studies, which interviews 10 cases of homeshare in Seoul. The contents of the research are investigated shared spaces of the elderly, and analyzed contents of interaction lives in shared spaces. The elderly experience loneliness while living alone, and having someone to live with gives them comfort and a sense of security, and this is one motive for participating in homeshare. The elderly and the young share many equipment and shared activities and interactions in shared space. The homeshare program makes it possible for the elderly to aging in place and have interactive relationships with different generations. Therefore, homeshare may the formation of a new family, and new dwelling utilizing the elderly's house.

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 attempted to clarify differences in sizes and shapes of foot between 20's and 60-70's women and analyzed the characteristics of elderly women's foot shapes as compared with those of young. The 2D data were 101 elderly and 101 young women in Seoul and Gyeonggi-do. The results are as follows: Firstly, the foot length of the elderly was shorter than that of the young, the foot breadth and the heel width were widened, but the toes breadth became smaller and the deformity of the toe 1 and the first metatarsal part appeared. Secondly, in the Foot Index, there was a significant difference in age group, the young is more than the elderly in the narrow type, standard type, the elderly women showed more than three times the young in the wide type. Thirdly, in the factor analysis for the foot type classification, 'foot length' factors in both age groups were large. Next, young group were influenced by 'toes breadth', lateral ball breadth' factors, elderly group was influenced by the 'lateral ball breadth', 'medial ball breadth' factors. Lastly, in the cluster analysis of the elderly group, the types of sole were classified as W-Type(20.8%, wide foot and toes, large heel), H-type(20.8%, small toes breadth, heel), D-type(31.7%, long length and wide lateral ball) and A-Type(26.7%, which is found only in the elderly, small length and large toes angle). As a result, it is necessary to design the shoes that match the characteristics of the soles of the elderly women.

The purpose of this research is to identify the characteristics of the positive and negative expressions about residential common life between the elderly and the young and present the direction on Homeshare. In-depth interviews were conducted from Feb. to May 2016 to identify the experiences of residential common life with 10 elderly and 11 young. The result is as follows. First, Homeshare dwelling was classified into five themes of human being, residential environment, life, management and emotion. Homeshare unlike ordinary dwelling centered on blood relatives, is characteristic to involve the management that connects between the elderly and young. Second, both the elderly and young were analyzed to be positive about the residential common life. It was shown that the elderly are most positive about human being, whereas young are positive about management and residential environment. The elderly is positive to mutual exchange with the young and young's independent life but the young is positive to factors that support comfortable personal life. Third, negative expression was shown a generation gap between the elderly and the young. The elderly recognized to be negative that young people has lived freely without consideration for the elderly. In order to solve these factors, it is necessary to make improvements through arranging rules for living. Fourth, three themes, human being, residential environment and life, analyzed to be the most important factors to sustain residential common life of Homeshare. The link between management and 3 themes leads to an expansion of positive emotion, which is structurally stable and is expected to increase the sustainability of the residential common life on Homeshare.

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.

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.

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.

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 is to help produce highly comfortable and wearable and footwear based on the establishment of basic data for manufacturing elderly footwear patterns and products. For this, a survey of 207 women in their 20s and 60-70s was conducted to identify the wearing of shoes, inconvenience areas, purchase practices and footwear preferences by age group. The results are as follows. First, the average age of the young female group was 22.5 years old, the elderly female group was 68.8 years old, and the average shoe size was 236.3 mm for the young female group and 238.3 mm for the elderly female group. Second, young women wore shoes for a longer time than elderly women, resulting in swollen and numb legs, hardened soles, uncomfortable toes and sore heels. However, elderly women felt more uncomfortable wearing footwear than young women. They suffered pain in the joint area, heal and toe areas as well as had more toe deformations due to aging. Third, all age groups preferred athletic shoes and loafers as well as purchases from footwear brand stores and department stores. The elderly spent more money on shoes, longer time to buy and valued the feeling of wearing, whereas the young considered design first. Fourth, both age groups prefer low-heels and natural leather, the young preferred to wear various types of shoes; however, the elderly are found to desire shoes that are comfortable and stable in both form and wearing.

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.
