This study examined the effectiveness of the cognitive activity integration program to delay the progression of the mild demented elderly. The subjects were divided into experimental group and comparative group for 12 cases of mild dementia, and the cognitive activity integration program was conducted for 8 weeks and compared with the MMSE-K, ADL & IADL, CDR and GDS scales. The results show that the effectiveness and continuity of the program are as follows. First, as an implication of practical dimension, integrated program of fusion and complexity is more effective than cognitive activity program of single domain. Second, the cognitive activity integration program must be continuously provided to maintain its effectiveness. Third, the cognitive activity integration program is as important as the practice process. It is necessary to develop and disseminate a cognitive activity integration program that reflects fusion and complex treatment techniques applicable to the elderly with mild dementia by practical suggestion. Policy suggestions are needed to continue the ongoing cognitive activity integration program, to maintain effectiveness, and to delay the progress of dementia.

A standard air flow generator system was developed to generate air flows of various levels simultaneously applied to two different air flow transducer modules. Axes of two identical standard syringes for spirometer calibration were connected with each other and driven by a servo-motor. Linear displacement transducer was also connected to the syringe axis to accurately acquire the volume change signal. The user can select either sinusoidal or square waveform of volume change and manually input any volume as well as maximal flow rate levels ranging 0~3 l and 0~15 l/s, respectively. Various volume and flow levels were input to operate the system, then the volume signal was acquired followed by numerical differentiation to obtain the air flow signal. The measured volumes and maximal air flow rates were compared with the user input data. The relative errors between the user-input and the measured stroke volumes were all within 0.5%, demonstrating very accurate driving of the system. In case of the maximal flow rate, relatively large error was observed when the syringe was driven very fast within a very short time duration. However, except for these few data, most measured flow rates revealed relative errors of approximately 2%. When the measure and user-input stroke volume and maximal flow rate data were analyzed by linear regression analysis, respectively, the correlation coefficients were satisfactorily higher than 0.99 (p < 0.0001). These results demonstrate that the servo-motor controls the syringes with enough accuracy to generate standard air flows. Therefore, the present system would be very much practical for calibration process as well as performance evaluation and comparison of two different air flow transducer modules.

Considering the characteristics of the Korean family which maintain a close connection with their patients from the moment of their falling sick to hospitalization to discharge, the family is the most important environmental factor of the social supporting system, and is the important object of the client as well as activity system. The medical social work intends to meet the practical needs of aged chronic patients, providing them and their family with a professional human service. The end of this study is to find out the hardships of both the aged chronic patients and their family as well as their needs for the social welfare service, and to search out the way of comprehensive social work service. The summary of the analysis of the survey is as follows: 1. The needs of aged chronic patients are divided into those of the solution of the problems of falling ill, social welfare program and discharge. Those needs arc affected by the various factors of the types of hospitals, the patients' age, the kinds of insurance, and the supporting systems, etc. Accordingly, the assessment of the needs of the patients are asked to be done comprehensively in accordance with the kinds of diseases and social environments. 2. The importance of the family to the aged chronic patients is evident. The family plays a decisive role in the patients' hospitalization and discharge, the family being an important supporting system and making it necessary to take an approach to client system. The family has difficulty in getting connection of community resources, in adapting to social life after the patient's discharge, and in paying the treatment. The family suffers the secondary hardships more than the burden of the treatment expenses. 3. For this reason various interventions are needed to reduce the stress caused by supporting and nursing patients. Thus the social welfare service for the aged chronic patients and their family needs the following prepositions: 1. It is the characteristics of the aged chronic patients that they need continuous care and that the strengths of the patients and their family cannot be too much emphasized, and that comprehensive assessment based on the connection 'with the community and the mutual interchange 'with the environment, is much emphasized. 2. The family of the aged chronic patient is a resources system as well as a client one. 3. Another characteristic of the aged chronic patients is that with the resources connection in mind, it needs an active intervention of social workers in the community. With these prepositions considered, the development of practical social work service for the aged chronic patients is thought urgently needed.

Purpose: This study was conducted to examine the effects of simulation-based infection control training on the ICU nurses' perception, clinical performance, and self-efficacy of infection control. Methods: Thirty-eight nurses were assigned into two groups using a career stratified randomization. In the experimental group, the subjects received a simulation-based infection control training, whereas the control group participated in a conventional lecture-based training. Two weeks after the completion of the training sessions, the participants were evaluated for perception, clinical performance, and self-efficacy regarding the infection control. Results: The experimental group that received simulation-based infection control training showed an improvement in perceiving the infection control compared to that of the control group, but the difference was not statistically significant. In terms of the clinical performance, the experimental group and the control group scored $26.05{\pm}3.22$ and $18.53{\pm}3.37$ points respectively, demonstrating a statistical significance (p<.001). There was no significant difference between the two groups in regards to the self-efficacy. Conclusion: The developed simulation-based infection control training showed positive effects in improving clinical performance of infection control over conventional lecture-based training, confirming that a simulation-based training is an effective method in advancing the practical performance of ICU nurses.

Background: The majority of deaths from cancer occur in low and middle income countries, partly due to poor public awareness of the signs and symptoms of cancer. Materials and Methods: A community based survey using the Cancer Awareness Measure (CAM) questionnaire was conducted in three different communities in Oman. Omani adults aged 18 years and above were invited to participate in the study. Results: A total of 345 responded from 450 invited participants (response rate=76.7%). The majority of respondents were unable to identify the common signs and symptoms of cancer identified in the CAM (average awareness was 40.6%). The most emotional barrier to seeking help was worry about what the doctor might find (223, 64.6%); a practical barrier was too busy to make an appointment (259, 75.1%) and a service barrier was difficulty talking to the doctor (159, 46.1%). The majority of respondents (more than 60% for seven out of ten symptoms) would seek medical help in two weeks for most signs or symptoms of cancer. Females were significantly more likely than males to be embarrassed (p<0.001), scared (p=0.001), and lack confidence talking about their symptoms (p=0.022). Conclusions: Urgent strategies are needed to improve public awareness of the signs and symptoms of cancer in Oman. This might leads to earlier diagnosis, improved prognosis and reduced mortality from cancer.

Purpose: This study aimed at exploring treatment delay (TD) among cancer patients in China with an attempt to develop a practical methodology facilitating frontline Chinese clinicians in promoting earlier cancer diagnosis and treatment. Materials and Methods: The study comprised framework development, qualitative interviews and paired factor rating. Framework development utilized systematic literature review, soft systems thinking and consensus groups. Qualitative interviews employed a checklist of open questions soliciting information about all the domains included the framework from cancer patients drawn via stratified randomized sampling of inpatients at 10 hospitals in Hefei, China. Paired factor rating used a self-developed computer aid and the interviewed patients as referring cases to weigh the relative importance of the factors listed in the framework in terms of their contributions to specific components of total delay (TD). Results: a) A conceptual framework was proposed consisting of a 6-step path to TD and 36 category determinants. b) A total of 227 patients were interviewed; their TD was 267.3 mean or 108 median days ranging from 0 to 2475 days; average appraisal, illness, behavioral, preparation and treatment delay accounted for 52.1%, 9.4%, 0.30%, 8.8% and 29.4% of the TD respectively. Individual side factors were rated substantially more important than environmental side factors (60% vs. 40%); most influential TD factors included cancer symptoms, overall health, family relations and knowledge about cancer and health. Conclusions: The framework proposed together with the interviewing and rating approaches used provide a potential new methodology for understanding cancer patients' TD and promoting earlier cancer treatment.
