The purpose of this study was to develop and validate the scale to measure dementia patient's caregiver burden of Korea. In the first phase of the study, 15 caregivers of dementia patients were interviewed to provide narrative data from which items were developed. Initially 65 items were generated from the interview data of 15 caregivers. Content validity was judged by two separate panels of experts with 27 professionals and 30 family caregivers. These items were analyzed through the Index of Content Validity and 33 items were selected which met .80 or more of the CVI. This preliminary FCBSD-K was tested with 207 adult caregivers for reliability and construct validity including item analysis and orthogonal(Varimax) factor analysis. Eight items were deleted because of high or low item-item correlation. The result of the second factor analysis produced six factors that coincided with the conceptual framework posed for the scale developed. The six factors were labeled as 'physio social factor' 'emotional factor' 'family cultural factor' 'role obligation' 'guilt feeling' and 'financial & supportive system factor'. The alpha coefficient relating to internal consistency was .9264 for reliability. In conclusion, cultural factor is related to dementia patient's caregiver burden and FCBSD-K was useful in assessing the dementia patient's caregiver burden in Korea.

This study was carried out response surface analysis for brown sauce optimization. Three factors of heating time (10, 20, 30, 40, and 50 min), the added gelatin content (0, 4, 8, 12, and 16%) and the added tomato paste amount (0, 6, 12, 18, and 24%) were encoded into 5 levels (-2, -1, 0, 1, 2). After the central synthesis plan was set up to produce samples in 16 pre-arranged conditions and the sensory tests were conducted, the investigation on optimum level of these factors was conducted. The scope of optimum conditions for extraction was established through reading the range of reaction surfaces superimposed between those representing sensory properties such as color, flavor, taste, viscosity and overall acceptability was established. In this study, it was found out that the scope of optimum conditions for brown sauce extraction was 30 min for heating time, 9.00% for gelatin content and 11.25% for tomato paste amount. The reliability test proved the mentioned scope to have a similar value to that of the estimated scope when compared to the experimental values which was observed through experiments conducted under the same conditions as applied to values predicted through RSM program, enabling the verification of the reliability of derived regression formula.

Purpose: The purpose of this study was to develop and validate a Nurse's Character Scale for Care in Clinical settings (NCS_C). Methods: The NCS_C was developed and validated as follows: Item generation, preliminary test of questionnaire, and tests of validity and reliability. One hundred and thirty six preliminary items were developed through a literature review and in-depth interviews by 10 nurse-experts and five patients. The content validity of the items was verified through an evaluation by five nurses and seven professors in the fields of Korean literature, pedagogy and nursing. Finally, 53 items were confirmed through item analysis, factor analysis and validity tests including convergent, discriminant and concurrent validities. Data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: Thirteen factors evolved from the factor analysis, which explained 63.1% of the total variance. The factors referred to the union of two dimensions: the professional dimension and the interpersonal dimension. The internal consistency, Cronbach's alpha, was .95, and reliability of the subscales ranged from .58 to .87. Conclusion: The results of this study suggest that the NCS_C is a reliable and valid primary scale to measure nurses' or students' character level for better care in clinical settings.

Purpose: The survey was performed to explore nurses' attitudes toward migrant wives in Korean society. Method: Four hundred thirty-eight respondents were recruited from 2 acute hospitals from 2 different geological areas. The attitude inventory to measure attitude toward migrant wives was utilized, which includes 6 factors such as prejudice, reliability, offensiveness, interests, acceptance, and influence. Result: The overall attitude was slightly positive (3.23) and reliability was the only non-positive scoring factor. Among the general characteristics education level showed a significant difference in 5 factors consistently compared to other characteristics. Conclusion: It can be concluded that Korean nurses tend to take a neutral to slightly positive attitude toward migrant wives. Therefore, any influence from nurses' attitudes related to migrant wives can be ignored. Obstacles or barriers which could hamper nursing care for migrant wives need to be identified and studies of strategies to overcome any existing barriers are called for.

Due to the need of data for a Human Reliability Analysis (HRA), a number of data collection efforts have been undertaken in several different organizations. As a part of this effort, a human error analysis that focused on a set of simulator records on a Steam Generator Tube Rupture (SGTR) scenario was performed by using the Human Event Repository and Analysis (HERA) system. This paper summarizes the process and results of the HERA analysis, including discussions about the usability of the HERA system for a human error analysis of simulator data. Five simulated records of an SGTR scenario were analyzed with the HERA analysis process in order to scrutinize the causes and mechanisms of the human related events. From this study, the authors confirmed that the HERA was a serviceable system that can analyze human performance qualitatively from simulator data. It was possible to identify the human related events in the simulator data that affected the system safety not only negatively but also positively. It was also possible to scrutinize the Performance Shaping Factors (PSFs) and the relevant contributory factors with regard to each identified human event.
