Purpose: This study investigated elderly women's health care at doctorless farm villages based on information-about the perception and management of their health. Method: Grounded theory method as mapped out by Strauss and Corbin-was used to record and transcribe open-ended interviews. The data from these interviews were analyzed. Result: We found 18 categories and 28 sub-categories. In data analysis, the core phenomenon was named "movement in pain". Causal condition as essential prerequisites were aging symptoms, bad state of health, comfortable life to live alone, longevity, deficiency of health care resources, and sub-categories of the phenomena revealed acceptance of discomfort, enduring pain, continuity of movability. Elderly women's health-related activities included enduring as it is, movement consciously, applying resources, difficult in using health medical institutions. Family support, economic level, disease condition, support system of community were influenced to their health-related activities. Consequently, the results indicated that they wanted to accept given life, expected easy death. held out remaining life. Conclusion: This study revealed that the most important factor of elderly women's health care was "movement in pain". On the basis of this study, we needed to develop diverse nursing implementation plans for maintaining and improving' movability without pain'.

Purpose: The purpose of this study was to classify the elderly in long-term care facilities using the Resource Utilization Group(RUG-III) and to examine the feasibility of a payment method based on the RUG-III classification system in Korea. Method: This study measured resident characteristics using a Resident Assessment Instrument-Minimum Data Set(RAI-MDS) and staff time. Data was collected from 530 elderly residents over sixty, residing in long-term care facilities. Resource use for individual patients was measured by a wage-weighted sum of staff time and the total time spent with the patient by nurses, aides, and physiotherapists. Result: The subjects were classified into 4 groups out of 7 major groups. The group of Clinically Complex was the largest (46.3%), and then Reduced Physical Function(27.2%), Behavior Problems (17.0%), and Impaired Cognition (9.4%) followed. Homogeneity of the RUG-III groups was examined by total coefficient of variation of resource use. The results showed homogeneity of resource use within RUG-III groups. Also, the difference in resource use among RUG major groups was statistically significant (p<0.001), and it also showed a hierarchy pattern as resource use increases in the same RUG group with an increase of severity levels(ADL). Conclusion: The results of this study showed that the RUG-Ill classification system differentiates resources provided to elderly in long-term care facilities in Korea.

Purpose : As the intensive care unit (ICU) survival rate increases, interest in the lives of ICU survivors has also been increasing. The purpose of this study was to identify the sentiment of ICU survivors. Method : The author analyzed the quotations from previous qualitative studies related to ICU survivors; a total of 1,074 sentences comprising 429 quotations from 25 relevant studies were analyzed. A word cloud created in the R program was utilized to identify the most frequent adjectives used, and sentiment and emotional scores were calculated using the Artificial Intelligence (AI) program. Results : The 10 adjectives that appeared the most in the quotations were 'difficult', 'different', 'normal', 'able', 'hard', 'bad', 'ill', 'better', 'weak', and 'afraid', in order of decreasing occurrence. The mean sentiment score was negative ($-.31{\pm}.23$), and the three emotions with the highest score were 'sadness'($.52{\pm}.13$), 'joy'($.35{\pm}.22$), and 'fear'($.30{\pm}.25$). Conclusion : The natural language processing of AI used in this study is a relatively new method. As such, it is necessary to refine the methodology through repeated research in various nursing fields. In addition, further studies on nursing interventions that improve the coherency of ICU memory of survivors and familial support for the ICU survivors are needed.

This research is to develop PPG filtering method for respiration measurement in U-Health Care system. Respiration rate was determined by filtering PPG and analyzing its spectrum. Optimal filter of PPG has been selected to get respiration by testing 120 sets of experiment data using 700 filtering cases. As a result, 2nd order Bessel-filter that used band-pass cutoff frequency at 0.175~0.4Hz with second order was good at developing respiration signal. Respiration signal in time domain could be continuously analyzed by converting frequency domain using spectrum analysis. 24 seconds has been found to be optimal time duration of collecting PPG data for determining respiration. Therefore, this study was successful of getting not only heart activity but also respiration by only PPG. Minimal invasive measurement obtaining multi-bio information by one sensor can be expected to apply to U-Health Care and human computer interaction.

Purpose: This study aimed at developing a novel tube thoracostomy technique using the sternum, a fixed anatomical structure, as an indicator to reduce the possibility of incorrect chest tube positioning and complications in patients with chest trauma. Methods: This retrospective study analyzed the data of 184 patients with chest trauma who were aged ≥18 years, visited a single regional trauma center in Korea between April and June 2022, and underwent chest computed tomography (CT) with their arms down. The conventional gold standard, 5th intercostal space (ICS) method, was compared to the lower 1/2, 1/3, and 1/4 of the sternum method by analyzing CT images. Results: When virtual tube thoracostomy routes were drawn at the mid-axillary line at the 5th ICS level, 150 patients (81.5%) on the right side and 179 patients (97.3%) on the left did not pass the diaphragm. However, at the lower 1/2 of the sternum level, 171 patients (92.9%, P<0.001) on the right and 182 patients (98.9%, P= 0.250) on the left did not pass the diaphragm. At the 5th ICS level, 129 patients (70.1%) on the right and 156 patients (84.8%) on the left were located in the safety zone and did not pass the diaphragm. Alternatively, at the lower 1/2, 1/3, and 1/4 of the sternum level, 139 (75.5%, P=0.185), 49 (26.6%, P<0.001), and 10 (5.4%, P<0.001), respectively, on the right, and 146 (79.3%, P=0.041), 69 (37.5%, P<0.001), and 16 (8.7%, P<0.001) on the left were located in the safety zone and did not pass the diaphragm. Compared to the conventional 5th ICS method, the sternum 1/2 method had a safety zone prediction sensitivity of 90.0% to 90.7%, and 97.3% to 100% sensitivity for not passing the diaphragm. Conclusions: Using the sternum length as a tube thoracostomy indicator might be feasible.

Purpose: The purpose of this study was to provide the data for improving home care services through investigating the recognition of home care services by nurses, doctors and general employees. Method: The data were collected from 231 nurses, 103 doctors and 157 general employees who were working at a general hospital in Seoul from Sept 11 to Sept 24, 2006 and analyzed using descriptive statistics and ANOVA. Results: The recognition on necessity of home care services was lower in doctors(M=2.73, SD=.39) and general employees (M=2.83, SD=.31) than nurses(M=3.13, SD=.39). In terms of the recognition on content of home care services, the affirmative percentages of most items were lower in doctors and general employee than nurses. The recognition on effects of home care services was also lower in doctors(M=2.90, SD=.32) and general employees(M=2.99, SD=.31) than nurses(M=3.26, SD=.35). Conclusion: This study indicates that the continuous educations and advertisements on home care services are necessary to facilitate home care services in general hospitals.

Purpose: The purpose of this study was to examine the relationships among self-care, self-care agency, self-efficacy, and quality of life in type II diabetic patients registered at a public health center. Method: The study subjects were 128 type II diabetic patients who were living in G city. The data were collected from March 2001 to February 2002. The instruments used for this study were the self-care scale developed by Jeung(1997) and designed by Park (1984) based on the original scale, the self-care agency scale developed by So (1992), the self-efficacy scale developed by a Jeung (1997) and designed by Paek (1996) based on the original scale, and the quality of life scale developed by Ro (1988). The data were analyzed using descriptive statistics, pearson correlation coefficient, and stepwise multiple regression. Results: 1. The relationships among self-care, self-care agency, self-efficacy, and quality of life were significant. Self-care was significantly related to self-care agency (r=.609. p<.01), self-efficacy (r=.763. p<.01), and quality of life (r=.493. p<.01). 2. The stepwise multiple regression analysis was performed to identify factors influencing quality of life of the subjects. The most powerful predictor was self-care agency (48.4%). The combination of self-care, complication status, age, education level, and self-efficacy accounted for 88.7% of the variance of quality of life in type II diabetic patients. Conclusion: The results suggest that self-care, self-care agency, self-efficacy, and quality of life are important variables for development of nursing intervention programs for patients with diabetes.

Purpose: This study was performed to evaluate the outcomes of the home care nursing program conducted jointly by thirty two catholic churches and C hospital in Seoul. Method: The subjects included 173 patients who registered for the program during a 4 month-period from November 1, 2004 to February 28, 2005 and received home care services for more than 4 times and 32 professional nurses participating in the program. Using the concept of medical outcome study (MOS), the structure, process, outcome elements were analyzed. Result: 1) A Catholic homecare nursing center and nurses of the C hospital played a central role in providing nursing care, and each church operated its own vehicle from its own office. Home care nurse's job satisfaction was 2.8 out of total score of 4. The major illness was cerebrovascular disease including stroke followed by skeletomuscular disease including degenerative arthritis cancer, and diabetes. Among reasons for accessing the home care nursing program, hypertension management was most prevalent. More than half of the registration was done through catholic churches. Most people who referred the patient to the program was through the church. Most patients received home care nursing 1-2 times a week for 30 to 60 minutes in average and the most frequent type of service provided was basic nursing. 3) The most frequent reason for terminating home care services was death. The change in PPS(Palliative Performance Scale) level from the time of registration and after 4 visits was the same in 45%, decreased in 30%, and improved in 25%. Patient satisfaction was very high, showing 3.4 out of total score of 4. Conclusion: These results proved that the home care nursing program was highly appreciated by subjects and nurses were providing professional care. Thus the two parties involved in the program were actively supporting the program to fulfill their mission. However, several areas needed to be improved such as relating with local community, relating with family doctor, and issue of improving the working conditions for home care nurses.
