Expert systems emerged during early 1970s have become one of the most important innovations in computer science. They actively work in various areas and achieve a big success especially in medical domain. It is to be difficult to obtain reliable recognitions about each diagnosis that has common characteristics and to manage data about over 140 nursing diagnoses by using existing Nursing Diagnosis System with artificial neural network. But a rule-based approach has been studied to automate diagnosis and is more effective that nursing diagnosis depends on objective data and has more common characteristics. In this paper, Nursing Diagnosis System was built with a rule-based approach due to the above reasons. Nursing Diagnosis System is implemented by using rules of production system, a kind of knowledge representation technique based on standardized nursing care plans. The ten nursing diagnoses, found most frequently from the patients on medical-surgical wards were determined to develop Nursing Diagnosis System. To verify the usefulness of Nursing Diagnosis System was tested with 80 patient's data. A diagnosis was judged correct if the system and the nursing experts agreed on diagnosing. The nursing experts evaluated 100 percents of the system's diagnosis was deemed correct. Judging from the results given above, the system seems highly reliable. In this work, I show that it can contribute to clinical application of nursing process as another nursing tool.

With growing need in the field, the application of computers in nursing has been frequently studied to improve the quality of nursing care in Korea. But the development of useful clinical programs has not received adequate alternatives. The aim of this study is to compare of two Nursing Diagnosis Systems - Neutral Network and Expert System. The simulated output of each Nursing Diagnosis System and the Judgment from the researcher and two professors of nursing were comparatively examined. The misdiagnosis rate of Nursing Diagnosis System using the Neural Network was nine percent, while the Nursing Diagnosis System using the Expert System showed consistency with those three experts in every aspect. Accordingly, the result of this study demonstrated the possibility of application of a nursing diagnosis system as another nursing tool.

BACKGROUND: Osteoporosis is the most common metabolic bone disorder. Osteoporosis has emerged as a leading public health problem with elderly persons and its detection is important for prevention and treatment of fracture. this population-based study was conducted to evaluate the prevalence and risk factors of osteoporosis in the elderly women. METHODS: One hundred thirty eight women aged 60 years or older in rural area were investigated with questionnaires and measurements of height, weight. Bone mineral density(BMD) measurements of lumbar spine and femoral neck were made with dual energy X-ray absorptiometry(DEXA). The World Health Organization criteria for diagnosis of osteoporosis using the manufacturer's young adult population mean and our study young population mean have been applied. Our study's young adult population mean was derived using normal premenopausal 37 women aged 30~45 years. RESULTS: The prevalence of osteoporosis was 45.7% for lumbar spine, 13.0% for femoral neck by the manufacture's young adult mean and 63.0% and 34.8% by our study young adult population mean, respectively. Weight and smoking were associated with lumbar spine BMD. Age was associated with femoral neck BMD. CONCLUSION: Our data suggest that the prevalence of osteoporosis is dependant on reference population mean and measurement site.

PURPOSE: The purpose of this study was to examine lifestyle, BMI, BP, and lipids profiles in male subjects and to explore the relationships among variables. METHODS: A total of 148 male subjects were recruited from one life insurance company from December 1, 2005 to February 28, 2006. Data collection methods were structured questionnaire, anthropometry and serum analysis. The relationships among lifestyle, BMI, BP, and serum lipid profiles were assessed by descriptive analysis, t-test, ANOVA, and partial Pearson's correlation coefficient of variables after controlling for age, educational level, and economic status. RESULTS: The mean BMI of the participants was relatively high as 25.38(range: 18.38 - 32.83). The differences of serum lipid profiles according to age, educational level, and economic status were significant. 'Use of caffeine and drugs'(r = -.187, p < .05) and 'consciousness of safety'( r= -.200, p < .05) was negatively related to BMI. Higher score of 'type of personality' domain was correlated with lower systolic BP(r = -.221, p < .01) and lower diastolic BP(r = -.195, p < .05) and was positively correlated with HDL(r = .191, p < .05). CONCLUSION: 'Use of caffeine and drugs', 'consciousness of safety' and 'type of personality' of lifestyle as well as 'dietary habit' and 'exercise' played a key role in circulatory disease.

Following the introduction of instrumentation for phacoemulsification and vitctomy, many other devices have been deaigned to perform the functions. In the past, there was a serious prblem that fluid flowed from the eye along the path of least resistance and the dutflow rate varied greatly with viscosity and consistency of material in the line. Recently a new computerized instrument the Heslin/Mackool Ocusystem that overcame these flow problems was developed and we studied about early experiences using this new helper. The results were as follows: 1. There was an advantage for time and place due to a single instrument and simple change from E.C.C.E. to vitrectomy. 2. The rupture of posterior capsule in aphakic group and the remained cortical material in pseudophakic group were the most common surgical complications during operation. 3. Descemet's membrane stripping was developed in a high rate due to the sharp titanum-covered cap of the handpiece for phacoemulsification. 4. The posterior capsule opacity was the most common postoperative complication in the group of visual acuity less than 0.5.

With the rapid growth of research and recognition about usefulness and importnace of the Nursing Diagnosis, the demand for application of Nursing Diagnosis has never been stronger. But in clinical field, not many nurses has used Nursing Diagnosis. Especially, nursing student have a difficulty to use Nursing Diagnosis because it demands for high level of capability of analyzing collected data and combining with relevant references. Therefore. this research has developed Nursing Diagnosis Self-learning Program using Back-propagating Neutral Network Model which is based on 98 surgery patients' data for nursing student. The twenty-six nursing diagnoses based on NANDA Taxonomy with 189 cases' reports and aid of 8 nursing experts wee determined to develop the program. To verify the usefulness of Nursing Diagnosis Self-learning Program constructed with the fully trained neural nets, the Program was tested with 70 real patients' data. The simulated output of program was compared with the judgement of the researcher and of two experts of nursing. The misdiagnosis rate of this program was eleven percent. This Program needs input of Signs and Symptoms, risk factors and 'related to' factors and also input the nursing diagnoses which a student selects. And than prints out two types of diagnoses. One is from the system and the other is what the student inputed. And the student makes the final diagnosis by refering the two types of diagnoses. Finally, the program prints out the completed diagnosis which problem combines with etiology in the diagnosis producing module. The program helps students to improve her capacity related to use Nursing Diagnosis.

PURPOSE: This study aimed to investigate the influence of resilience and symptom experience on quality of life. METHODS: Seventy five patients in an active treatment stage were recruited from 2 hospitals between October and December 2010. A survey including perceived health status, physical functional status, the symptom experience index, resilience, and the functional assessment of cancer therapy-colorectal (FACT-C) was completed. RESULTS: The level of FACT-C was 86.61 (+/-18.91), which was higher than for patients with colostomy, but lower than for patients in a rehabilitation stage. Participants without physical functional limitations showed higher level of both resilience and quality of life. Participants with bad health status showed a lower level of both resilience and quality of life and higher level of symptom experience. The quality of life was related to the level of resilience (beta=.373), symptom experience (beta=-.292), and perceived health status (beta=-3.961). CONCLUSION: Proactive nursing approaches to manage symptoms and to improve perceived health status would enhance the quality of life of colorectal cancer patients. Furthermore, various strategies to strengthen the level of resilience should be developed.

PURPOSE: This study was done to explore the process of accepting CATs among nurses who experienced CATs in Korea. METHODS: Grounded theory methodology was utilized. Data were collected from 10 nurses during individual in-depth interviews. Theoretical sampling was used until the data reached saturation. Data were analyzed using the constant comparative analysis method. RESULTS: The core category emerged as "resolving the doubt and integrating" explaining the process of accepting CATs. The nurses engaged in three stages: need awareness, look for solution and integration. Causal conditions were interest as a nursing intervention and orthodox medical limitations. Context was lack of basis for application and increase in social interest. Strategies were new knowledge acquisition, having a strong will, combined with existing knowledge, and individualized intervention. Intervening conditions were others' eye, exhaustion for nurses and physical environment. Consequences were expanding of the nursing role and improved nurse satisfaction. CONCLUSION: The results of the study should facilitate application of CATs in nursing practice. To help nurses who are interested in CATs, there is a need for education programs, and further research on CATs.

Despite acknowledgment that pain is likely to be a major problem for many older adults, it is difficult to estimate the frequency of pain problems for this population. The main purpose of this study was to identify the various characteristics of chronic pain in the elderly by gender. It examines by gender, pain frequency, pain intensity, number of chronic pain sites, localization of pain, impact on activities, methods of pain management, and effects of chronic pain management. The subjects were 189 elderly people(65 years and older) living in an urban area. They were surveyed at their homes. They were surveyed by interview using a closed-ended questionnaire. The survey was done from Nov. 6th. to Dec. 6th. 1997. Descriptive statistics were used to determine all of the reported pain variables. Chi-square tests were used to determine crude differences between pain intensity and gender. T-test was used to determine differences in number of pain sites between men and women. The findings are as follows ; Of the 189 subjects, 83.6% reported experiencing pain, and men reported a lower prevalence(69.5%) than women(89.2%). Women had significantly more severe pain than did men(p=.001). Lower back pain(20.2%) and leg pain(20.2%) were the most prevalent, followed by knee pain(17.4%), arm pain(13.3%), neck and shoulder pain(11.6%), and headache(9.9%). Women experienced more multiple localizations of pain(p=.0001). The greatest impact was on movement(83.5%), followed by usual activities(60.8%), sleep(49.4%), visiting(29.1%), and hobbies and recreations(50.0%). No differences were observed between men and women in the proportion of subjects reporting a negative impact on each of these activities. The methods of pain management were hospital visit(70.9%), drug store medication(46.7%), oriental medicine clinic(32.9%), endurance(13.3%), self-management(6.3%). Drug therapy was the most effective pain management strategy(94%), followed by physical therapy(63%) and accupuncture byssocausis(55%). The conclusion: Pain is a symptom of great clinical importance that is often associated with disability, loss of independence, and reduced quality of life. In this study chronic pain symptoms were common but unevenly distributed in men and women. The results further advance understanding of the experience and impact of pain by gender. Future studies should incorporate questions that gather systemic and more detailed information on the characteristics of pain, expecially by gender and by age.
