Objective: This study was conducted to examine the effects of a health promotion program on the health condition of rural elderly women implemented at primary health care posts using Korean Frailty Index. Methods: The research was designed a nonequivalent control group pretest-posttest setting. The participants in this study were 50 residents (intervention group: 25, control group: 25) selected from 4 villages 2 primary health care posts in J city Gyeongsangnam-do. The health promotion program was conducted at the primary health care posts twice a week for 12 weeks. This program consisted of basic exercises(Gukseondo + Theraband muscle strength training) and additional activities(including modified Theraband activity, rubber ball exercise, ball massage, nutrition class, singing class). Collected data were analyzed by descriptive statistics, paired t-test, and repeated measures ANOVA with SPSS 21.0. Results: Results of the health promotion program showed that the health conditions(measured by perceived health status, frailty score, upper/lower flexibility, maximum grip strength, dynamic balance test Timed Up and Go) of the experimental group(25) all statistical significantly improved. Conclusion: Study findings indicate that the health promotion program implemented at primary health care posts on rural elderly women is effective and can contribute to a developed health promotion program for local residents in the future.

Ordinary survival analysis cannot be applied when a significant fraction of patients may be cured. A cure rate model is the combination of cure fraction and survival model and can be applied to several types of cancer. In this article, the cure rate model is considered in the interval censored data with a cluster effect. A shared frailty model is introduced to characterize the cluster effect and an EM algorithm is used to estimate parameters. A simulation study is done to evaluate the performance of estimates. The proposed approach is applied to the smoking cessation study in which the event of interest is a smoking relapse. Several covariates (including intensive care) are evaluated to be effective for both the occurrence of relapse and the smoke quitting duration.

The purpose of the present study was to develop a community-based intensive health care program for the community dwelling elderly to strength their functional status and to verify the effect on their geriatric syndrome. A one-group pretest-posttest design was used for the study. A total of 69 frail elderly, who lived in the area within 20 minutes by car, were committed themselves to the day care center(Sangikjae), and had the ability of verbal communication were selected from G city in Kyunggi province. The participants completed a set of questionnaires to measure the sub-score of frailty, fall, urinary incontinence, malnutrition, and mild cognitive disorder domain, using the Otasha-Kensin through the physical examinations and interviews. After 4 weeks of intervention, the outcome was measured to evaluate the effects of the program, and the data obtained were analyzed using descriptive statistics, paired t-test and McNemar test. The results showed that the sub-score of frailty, fall, urinary incontinence, and malnutrition domain were statistically significantly decreased after intervention except those of urinary incontinence and mild cognitive disorder domain, implying that the risk of frailty, fall, and malnutrition was decreased. These findings indicated that community-based the intensive health care program is effective for relieving geriatric syndrome of the community dwelling elderly.

Recurrent gap times are analyzed with diverse methods under several assumptions such as a marginal model or a frailty model. Several resampling techniques have been recently suggested to estimate the covariate effect; however, these approaches can be applied with a time-fixed covariate. According to simulation results, these methods result in biased estimates for a time-varying covariate which is often observed in a longitudinal study. In this paper, we extend a resampling method by incorporating new weights and sampling scheme. Simulation studies are performed to compare the suggested method with previous resampling methods. The proposed method is applied to estimate the effect of an educational program on traffic conviction data where a program participation occurs in the middle of the study.

In clinical studies, different types of outcomes (e.g. repeated measures data and time-to-event data) for the same subject tend to be observed, and these data can be correlated. For example, a response variable of interest can be measured repeatedly over time on the same subject and at the same time, an event time representing a terminating event is also obtained. Joint modelling using a shared random effect is useful for analyzing these data. Inferences based on marginal likelihood may involve the evaluation of analytically intractable integrations over the random-effect distributions. In this paper we propose a joint HGLM approach for analyzing such outcomes using the HGLM (hierarchical generalized linear model) method based on h-likelihood (i.e. hierarchical likelihood), which avoids these integration itself. The proposed method has been demonstrated using various numerical studies.

The purpose of this study is to propose the factors affecting collaboration between community nurses and social workers in Korea. Data that is used in this study, were collected from 295 provider respondents by questionnaire, additionally from telephone survey and secondary data review. This study focuses on the working relationship between professionals in the field of health and social care. Based on the literature review, this study proposes a conceptual framework for collaboration between nurses and social workers in community health and social care. The dependent variable in this study is collaboration. It reveals whether or not the inter-professional works and shows the level of collaboration. The independent variables are categorized in: the client characteristics (frailty of client, client-provider relationship); the provider characteristics (specialization, perception of interdependence, perception of the other professional); the organization characteristics (closeness of the other professional, autonomy, on-the-job training, evaluation-reward); and the community characteristics (urbanization, capacity of resources). Major findings are as follows: First, the factors that appear to have the strongest impact on whether or not inter-professional working of respondent sampled are: the perception of other professional; the perception of interdependence; closeness of, the, other professional; and the frailty of client. Secondly, the factors that found to have the most significant effect on level of cooperation are: the perception of, the other professional; on-the-job training; evaluation-reward; and the closeness of the other professional.

Physical exercise can be effective in preventing or ameliorating various diseases, including diabetes, cardiovascular diseases, neurodegenerative diseases, and cancer. However, not everyone may be able to participate in exercise due to illnesses, age-related frailty, or difficulty in long-term behavior change. An alternative option is to utilize pharmacological interventions that mimic the positive effects of exercise training. Recent studies have identified signaling pathways associated with the benefits of physical activity and discovered exercise mimetics that can partially simulate the systemic impact of exercise. This review describes the molecular targets for exercise mimetics and their effect on skeletal muscle and other tissues. We will also discuss the potential advantages of using natural products as a multi-targeting agent for mimicking the health-promoting effects of exercise.

Purpose: The purpose of this study was to investigate the effect of geriatric syndrome on mortality among community-dwelling older adults in Korea. Methods: Data were obtained from the Actual Living Condition of the Elderly and Welfare Need Survey, with a baseline study in 2008 and a 3-year follow-up of mortality data. The mortality risk was measured using the hierarchical Cox proportional hazard model. Results: In Cox regression analysis, male (Hazard Ratio [HR], 2.53; 95% Confidence Interval [CI], 2.12~3.01), old age (HR, 2.14; 95% CI, 1.82~2.53), low education level (HR, 1.31; 95% CI, 1.04~1.65), limitation in instrumental activities of daily living (HR, 1.91; 95% CI, 1.60~2.28), depressive symptoms (HR, 1.21; 95% CI, 1.01~1.43), and frailty (HR, 2.32; 95% CI, 1.78~3.03) significantly affected mortality risk. Conclusion: Based on the results of this study, nursing intervention programs should be provided to decrease preventable death in older adults.

Purpose : The aim of this study was to determine the effect of proprioceptive neuromuscular facilitation(PNF) on balance ability in poststroke hemiparetic subjects. Methods : The subjects of this study were 12 patients with hemiplegia who volunteered to participate in the experiment which was carried out over the course of 4 weeks. The Proprioceptive Neuromuscular Facilitation is applied to group with three positions (sidelying, half-standing, modified plantigrade). The tests between before and after the intervention were measured by FSST (Four Square Step Test), FICSIT-4 (Frailty and Injuries: Cooperative Studies of Intervention Techniques), BBS(Berg Balance Scale). The data were analyzed using paired t-test and Wilcoxon signed rank test to determine the statistical significance. Results : The results of this study were summarized as follows: 1. After intervention, the score of BBS and FICSIT-4 significantly were increased compared with before intervention. 2. After intervention, the time of FSST were reduced significantly compared with before intervention. Conclusions : According to above results, Proprioceptive Neuromuscular Facilitation improved with balance ability of patients with hemiplegia. This study provided basic data for effects Proprioceptive Neuromuscular Facilitation on balance ability. In conclusion, Proprioceptive Neuromuscular Facilitation with other interventions is effective way to improve balance ability of patients with hemiplegia.
