Purpose: The purpose of this study was to examine the effect of an obstacle height on the balance control of older adults while stepping over an obstacle from a position of quiet stance. Methods: Fifteen community-dwelling healthy older adults (mean age, $74.4\pm4.27$ yrs; age range, 67-82 yrs) volunteered to participate in this study. The subjects performed gait initiation (GI) and they stepped over obstacles of two different heights (10 cm and 18 cm) at a self-paced speed from a position of quiet stance. Their performance was assessed by recording the changes in the displacement of the COP in the anteroposterior (A-P) and mediolateral (M-L) directions using a force platform. Results: The M-L displacement of the COP significantly increased for an 18 cm obstacle height condition as compared to the GI and a 10 cm obstacle height condition (p<0.01). Furthermore, the M-L displacement of the COP for a 10 cm high obstacle was significantly greater for that for the GI (p<0.01). However, the mean of the A-P displacement of the COP was similar between the stepping conditions for the A-P displacement of the COP (p>0.05). Conclusion: This study suggests that the M-L COP displacement could be a better parameter to identify the dynamic balance control in older adults when negotiating obstacles.

Objectives: This study was to examine by gender the clustering patterns and correlates of healthy lifestyle clusters and the relationships between healthy lifestyle clusters and depressive symptoms in middle-aged and older adults. Methods: The observed/expected ratio of physical activity, smoking, and alcohol consumption were calculated to analyze clustering effects. The correlates of those healthy lifestyle clusters were evaluated using logistic regression models, and the relationship between those healthy lifestyle clusters and depressive symptoms was investigated using multiple regressions by gender. Results: Based on the guidelines this study adopted, we obtained three healthy lifestyle clusters: active healthy lifestyle; passive healthy lifestyle; and unhealthy lifestyle. All three clusters were found in men, but two in women, who did not have an unhealthy lifestyle cluster. High socio-economic status was positively related to healthy lifestyle clusters. Social participation and residence location (in men) and marital status (in women) were significant factors. Having an active or a passive healthy lifestyle was negatively associated with depressive symptoms in women, but such a relationship was not observed in men. Conclusions: The study findings imply that health promotion programs for middle-aged and older adults in Korea should be comprehensive and integrated, considering healthy lifestyle clusters and gender differences.

Purpose: We examined tobacco use pattern and its correlates among older adults. Materials and Methods: We used data of 9,852 older adults (${\geq}60$ years) (men 47% mean age 68 years) collected by the United Nations Population Fund on Ageing from seven Indian states. Logistic regression analysis was used to assess the correlates of tobacco use. Results: Current use of any form of tobacco was reported by 27.8% (men 37.9%, women 18.8%); 9.2% reported only smoking tobacco, 16.9% smokeless tobacco only and 1.7% used both forms. Alcohol users (OR:5.20, 95% CI:4.06-6.66), men (OR:2.92, CI :2.71-3.47), those reporting lower income (OR:2.74, CI:2.16-3.46), rural residents (OR 1.34, CI 1.17-1.54) and lower castes (OR:1.29, CI:1.13-1.47) were more likely to use any form of tobacco compared to their counterparts. Conclusions: Tobacco cessation interventions are warranted in this population focusing on alcohol users, men, those from lower income, rural residents and those belonging to a lower caste.

Purpose: The purpose of this study was to examine the psychometric properties of the Korean version of the General Practitioner Assessment of Cognition (K-GPCog) scale. Method: The K-GPCog consists of the 2 subscales, patients and caregivers. Using a sample of 412 community-based Korean older adults, internal consistency reliability was estimated using Cronbach's alpha. To evaluate validity of the K-GPCog, correlational analysis was conducted using Pearson r between K-GPCog and the Korean Dementia Screening Questionnaire (KDSQ). Results: Cronbach's alpha coefficients of the K-GPCog patients' and caregivers' subscales .788 and .794 respectively. Pearson's correlation coefficients were r=-.374, r=-.481, and r=-.493, respectively for the subscales of patients and primary caregivers, and total K-GPCog. The degree of diagnostic agreement about the risk for cognitive disorders of older adults showed 11.7% and 11.2% respectively for the K-GPCog and the KDSQ. Conclusion: The findings provided preliminary evidence of the K-GPCog as a useful screening measure for detecting mild cognitive disorders of Korean older adults. The K-GPCog is particularly useful to identify cognitive disorders from primary caregivers when it is difficult to assess the level of cognition of older adults.

Purpose: The purpose of this study was to examine changes in functional assessment measures (FAMs) and spatiotemporal gait parameters (STGPs) in healthy older adults before and after a 6-week intervention of a proprioceptive neuromuscular facilitation (PNF) training program. Methods: Thirty healthy older adults (mean age: $73.37{\pm}1.21$ age range: 65-79) were randomly assigned either to an experimental group (participating in a 6-week intervention of PNF training) or a control group (only performing daily activities). Participants in the control group did not receive any training program. Performance was assessed by recording changes in the FAMs and STGPs using functional assessment tools and GAITRite. Results: Participants in the PNF group showed significantly improved functional assessment measures and increased stride length, cadence, velocity, and step width (p<0.05). No significant differences in FAMs and STGPs were found in the control group (p>0.05). Conclusion: Participation in a PNF training program improves FAMs and STGPs, thereby increasing the ability of healthy older adults to maintain dynamic balance during functional performance and gait. These findings support the use of PNF training programs as effective fall-prevention programs for the elderly.

본 연구는 노령층의 온라인 커뮤니티 이용과 사회화 그리고 사회적 고립감 사이의 잠재적 관계에 대해 탐색해 보고자 했다. 위계적 회귀분석의 분석결과에 따르면, 온라인 커뮤니티 회원으로 구성된 개인적 네트워크의 크기와 질은 사회화에 긍정적인 영향을 미쳤으며 사회적 고립감 또한 저하시켰다. 그러나 온라인 커뮤니티의 회원들과의 오프라인 미팅의 유의미한 효과는 발견되지 않았다. 이에 더해, 온라인 커뮤니티를 이용하는 시간은 사회화로 매개되어 사회적 고립감에 유의미한 영향을 미쳤다. 이러한 연구결과는 제한된 사회적 관계로 인해 발생할 수 있는 심리적 문제들을 극복하는데 있어서 온라인 커뮤니티의 이용이 긍정적인 역할을 할 수 있음을 시사한다.

Purpose : The purpose of this study was to evaluate the effect of footwear on gait in older adults. Methods : The footwear consists of loafer with fixation and mule and slipper without fixation. Twenty one female older adults voluntarily participated in this study. Each participant walked on the gait system GAITRite and measured temporal-spatial gait parameters. And the participants wore loafer, mule, slipper randomly. We measured stance time, swing time, heel-to-heel BOS, double support time, velocity, cadence, FAP as temporal-spatial gait parameters. Results : Three gait parameters showed significant difference statistically among 7 gait parameters. The stance time increased as loafer, mule, barefoot, slipper orderly. And there was a significant difference statistically (p<.05). The swing time increased as slipper, barefoot, mule, loafer orderly. And there was a significant difference statistically(p<.05). And the heel-to-heel BOS increased as barefoot, loafer, mule, slipper orderly. And there was a significant difference statistically(p<.05) according to footwear type. Conclusion : The footwear type with high stability like loafer is considered better than footwear type with low stability like mule and slipper for the elderly.

Purpose: This study examined the difference in the center of pressure (COP) displacement time in older adults according to the obstacle height during stance at each sub.phase when crossing obstacles. Methods: Fifteen older adults were enrolled in this study (${\geq}65$ years of age). The F-scan was used to measure the COP displacement time when crossing a 0, 10 and 40cm obstacle, and the stance phase was divided into 4 sub-phases according to the foot contact pattern. Results: During the stance phase, the COP displacement time increased with increasing obstacle height. During the mid-stance, terminal stance and pre-swing except for the loading response, there were significant differences in the COP displacement time according to the obstacle height. Conclusion: This study suggests that older adults show differences in the COP displacement time according to the stance sub-phase while crossing obstacles, and they use different mechanisms according the sub-phases to maintain balance during obstacle crossing.

Purpose: This study aimed to prove the effects of the net-step exercise (NSE) on gait ability, depression, cognitive function and activities of daily living (ADL) in older adults. Methods: The study employed a non-equivalent control group non-synchronized design. A total of 64 community-dwelling older adults were recruited and divided equally into two groups; 32 subjects for an experimental group and 32 subjects for a control group. In the experimental group, the NSE was applied to an hour, two times per week for 4 weeks. The level of gait ability, depression, cognitive function and ADL were measured before and after NSE. The study conducted from July to August, 2016. Data were analyzed with descriptive statistics, $x^2$ test, Fisher's exact test, t-test, ANCOVA, and Pearson correlation coefficients using SPSS/WIN 22.0 version. Results: Gait ability, depression, cognitive function were significantly better in the experimental group than the control group. However, the difference in ADL was not significant between the two groups. Conclusion: These findings in this study showed that the NSE was an efficient intervention for older adults. Nurses could apply non-pharmacological interventions to avoid pharmacological side-effects.

Purpose: This study aimed to evaluate the effects of lifestyle modifications on the constipation relief, the time required to see the effects, and the effective lifestyles for constipation in older adults admitted to a geriatric hospital. Methods: Nonequivalent control group pre-post test design was used. The subjects consisted of 25 elderly in the control group and 23 in the experimental group. Constipation was measured with symptoms of constipation, number of bowel movement and use of laxatives. Life style modification consisted of drinking water before breakfast, having a breakfast, scheduled toileting after breakfast and walking everyday for 3 weeks. Results: Symptoms of constipation (t=2.23, p=.030) and number of bowel movement per week (t=-2.55, p=.014) were significantly different between two groups after 3 weeks. Drinking water, scheduled toileting and walking might contribute to the results. Conclusion: Lifestyle modification was effective on constipation in older adults admitted to a geriatric hospital. However, the effects were produced after 3 weeks. Nevertheless, it is recommended that nurses continuously encourage older adults for drinking water, regular trying for bowel movement and walking to relieve constipation, since the lifestyle modification does not need any special education and skill.
