The purpose of this study was to analysis level on family caregiver's burden for the elderly with senile dementia in a rural area and to choose priority care group, thereby facilitating the development of interventions to reduce the caregiver's burden. For this purpose, data were collected by questionaire from June 10 to October 8, 1994. The instruments for data collection were Caregiver Burden Inventory by Novak(1989) and Zarit et al(1982), severity of dementia by Hughes Scales (1982), ADL by Lawton (1971), patients' family caregiving activity by pre-survey and reference review(Lee, 1993 ; Jang, 1990 ; Yoo, 1982). The subjects were 60 family caregiver of senile dementia in a rural area. The data was analysed by the use of t-test, ANOVA, correlation and multiple regression. The results were as follows : 1. Total burden was evaluated over average, the mean of family burden was 61.24. 2. Significant variables which were correlated to the family caregiver's burden were the severity of dementia(F=30.52, p<0.001), ADL(F=5.43, p<0.01), PADL(F=6.14, p<0.01), caregiver's health status(F=6.05, p<0.01), a view of patient's prognosis(F=4.08, p<0.05), the number of hours per day spent on caregiving(F=19.64, p<0.001), level of intimacy of caregiver and patients(F=7.16, p<0.001), the frequency of caregiving activity(F=5.31, p<0.01). 3. ADL was the most important predictor to family caregiver burden(R2=0.6611). In addition to this, the severity of dementia, level of intimacy of caregiver and patient, relationship with the patient accounted for 79% of family caregiver burden. 4. The criteria of priority care group were as follows ; the mean of family caregiver burden was above 58, above of moderate ADL, the number of hours per day spent on caregiving above of 8 hours, above of moderate dementia. By the the severity of dementia, number of priority care group, mild dementia was 10(43.4%), moderate dementia 23 (92.0%), sever dementia 12(100.0%).

The increasing elderly population has created an urgent need for well-managed convalescent hospitals, which should provide appropriate clinical nutrition services. The new accreditation policy requiring participation of all convalescent hospitals since 2013 may promote improvement of clinical nutrition services. This study examined whether or not the accreditation policy has increased practice level and dietitians' perception of the importance of clinical nutrition management. Of the 177 convalescent hospitals accredited by January 30, 2014, dietitians from 73 hospitals (41.2%) completed the survey questionnaire. The pre-tested questionnaire surveyed general characteristics of the hospital and dietitians, current status of clinical nutrition management, and changes in the perception and practice levels of various aspects of food and clinical nutrition management. In average, dietitians with more than 5 years of work experience (68.1%) provided food and clinical nutrition services (71.2%). After accreditation, dietitians' perception of the importance and practice level of clinical nutrition service increased (P<0.001). Level of perception, however, was significantly (P<0.001) higher than practice level before and after accreditation. During perception and practice level of initial nutrition assessment, a compulsory accreditation item, notably and significantly (P<0.001) improved after accreditation. The significant difference between perception and practice level disappeared after accreditation. In conclusion, the accreditation process had positive effects on clinical nutrition management in terms of dietitians' perception and practice levels. Making more accreditation items compulsory and providing motivation and professional education to dietitians in convalescent hospitals could lead to additional improvements.

Background: The trend of aging society is occurring globally, and with it, one of the health problems that is emerging is frailty. Efforts are being made to account for the increasing prevalence of frailty, and various modifiable factors are being considered in regards to frailty. Because social contact has shown beneficial effects in terms of health in previous studies, it is increasingly being considered in relation to frailty. The purpose of this study was to assess the association of different types of social contact with frailty status. Methods: A total of 1,200 Korean elders aged 70-84 years old were included in the study. Using Fried's Cardiovascular Health Study index to categorize the frailty status, the relationship between frailty status and frequency of contact (i.e., with family members, friends, or neighbors) was analyzed using multinomial logistic regression accounting for confounders. Results: Adjusting for all covariates, frequency of contact with friends was the most statistically significant. Less frequent contact was associated with a significantly higher odds of pre-frailty: monthly (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.27-3.20), and rarely (OR, 1.87; 95% CI, 1.17-2.99), with daily contact group as reference. Also, those contacting friends monthly (OR, 5.04; 95% CI, 2.29-11.08) or rarely (OR, 3.23; 95% CI, 1.58-6.61) were more likely to be frail compared to the daily group. Conclusion: Frequency of social contact, especially with friends, is strongly associated with frailty.

Carbapenem-resistant Enterobacteriaceae (CRE) that produce Klebsiella pneumoniae carbapenemase are increasingly reported worldwide and have become more and more resistant to nearly all antibiotics during the past decade. The emergence of K. pneumoniae strains with decreased susceptibility to carbapenems, which are used as a last resort treatment option, is a significant threat to hospitalized patients worldwide as K. pneumoniae infection is responsible for a high mortality rate in the elderly and immunodeficient individuals. This study used Lactobacillus fermentum as a candidate probiotic for treating CRE-related infections and investigated its effectiveness. We treated mice with L. fermentum originating from the vaginal fluid of a healthy Korean woman and evaluated the Lactobacilli's efficacy in preventive, treatment, nonestablishment, and colonization mouse model experiments. Compared to the control, pre-treatment with L. fermentum significantly reduced body weight loss in the mouse models, and all mice survived until the end of the study. The oral administration of L. fermentum after carbapenem-resistant Klebsiella (CRK) infection decreased mortality and illness severity during a 2-week observation period and showed that it affects other strains of CRK bacteria. Also, the number of Klebsiella bacteria was decreased to below 5.5 log₁₀ CFU/ml following oral administration of L. fermentum in the colonization model. These findings demonstrate L. fermentum's antibacterial activity and its potential to treat CRE infection in the future.

Purpose: The purpose of this study was to examine effectiveness and usefulness of Information Communication Technology (ICT) in communication between physician and visiting nurses who provide visiting nursing services under long-term care insurance. Methods: Structured questionnaires were used to measure usefulness and satisfaction of the system, both accessibility and convenience to visiting nurses (31 people) and users (182 people). Results: From the user perspective, accessibility and convenience in terms of service users were both satisfactory as shown by users' percentage. No statistically significant difference was found for satisfaction between before and after using the system. The usefulness of the system for visiting nurses was satisfactory for most the nurses. Also most nurses answered that the system is needed and is very useful. Most of the participants (both visiting nurse and service users) were satisfied with use of the ICT system. However, there was no statistically significant difference in satisfaction between the pre and post service because the service provision period was too short (three months). Conclusion: The consensus from both users and service providers is that an ICT based visiting nursing system needs to be introduced but a more user - friendly environment for system development will be needed.

With the increase in number of the athletic population and elderly demographic, the demand for orthopedic splints, which are used to support a damaged body, has rapidly increased. Current splints mainly consist of inner and outer parts, which are multiple fabrics covered with polyurethane and nonwoven fabrics, respectively. However, the laminated materials with directly applied pre-polymer coating lead to a high defect rate because of the uneven thickness on the surface. Thus, this study proposes an indirect coating method using a precise clearance controller, which enables the even application of the coating material on multiple inner parts while maintaining a constant thickness. In addition, a roll-to-roll (R2R) technique is applied instead of the sewing mechanism to bond the inner and outer materials together and enhance the productivity in the final stage. In the advanced methods, there is a storage tank that contains polyurethane, a clearance controller, and pairs of rollers in the upper and lower rows. To improve the quality of the products and optimize the equipment, three controllable factors are determined: the viscosity of polyurethane, angle of the gap controller and number of pairs of rollers in the R2R system.
