  • The Jarque and Bera (1980) statistic is one of the well known statistics to test univariate normality. It is based on the sample skewness and kurtosis which are the sample standardized third and fourth moments. Desgagné and de Micheaux (2018) proposed an alternative form of the Jarque-Bera statistic based on the sample second power skewness and kurtosis. In this paper, we generalize the statistic to a multivariate version by considering some data driven directions. They are directions given by the normalized standardized scaled residuals. The statistic is a modified multivariate version of Kim (2021), where the statistic is generalized using an empirical standardization of the scaled residuals of data. A simulation study reveals that the proposed statistic shows better power when the dimension of data is big.

  • It is not stipulated concretely in the Food Sanitation Act what the standardized school food service dieticians indices and the dietician's duties and task elements should be. Therefore, this study was required. The specific purposes of this study were : a) to define the school food service dietician's duties and task elements, b) to estimate the performance frequency and work hours of the dietician's duties and task elements c) to investigate the job specification of the dietician over school food services, d) to develop the standardized indices of the dietician needed in school food service operation. For this study, school food service dietician's work functions were defined in 10 duties and 60 task elements based on the studies precedented and literature review and pilot test process. This study was conducted in school food service systems nationwide using written questionnaire and interview with the official in charge and delphi technique. The questionnaires were mailed to the dieticians of three types of school food service systems. Of the 660 schools that participated in this study, the 624 responses were selected for analysis. Statistical analyses were performed with SAS/Win 6.12 program so as to provide a descriptive statistics, T-test, ANOVA. The main results of this study could be summarized as follows: A characteristic common to all the school food service systems was that 'cooking and distribution management' took the longest hours of work, while 'nutrition education' took the shortest hours of work. The standardized index of dietician over school food service was one person in conventional system independently of the number of meals per day. In the commissary system, according to the numbers of meals served per day, it was 0.95-1.38 persons and 1.27-1.55 persons and 1.40-1.91 persons. In joint management system, the standardized index was 1.03-1.42 persons in case of serving less than 700 meals per day.

  • A central issue in the development of nursing practice is to describe the phenomenon with which nursing is concerned. To identify the health problems which can be diagnosed and managed by the nurse is the first step to organize and ensure the development of nursing science. Therefore the academic world has been discussing the application of the nursing diagnosis in nursing practice as a means of improving quality of care. The objectives of this study were to develop a standardized nursing care plan for ten selected nursing diagnoses to form a database for computerized nursing service. The research approach used in the study was (1) the selection of the ten nursing diagnoses which occur most frequently on medical-surgical wards, (2) the development of a standardized nursing care plan for the ten selected nursing diagnoses, (3) application of the plan to hospitalize patients and evaluation of the content validity by the nurses, and (4) evaluation of the clinical effects after the use of the standardized nursing care plans. The subjects were 56 nurses and 395 hospitalized patients on two medical and two surgical unit. The results of this study were as follows ; 1) The ten selected nursing diagnoses for the development of the standardized nursing care plans were “PAIN, SLEEP DISTURBANCE, ALTERED HEALTH MAINTENANCE, ALTERATION IN NUTRITION, ANXIETY, CONSTIPATION, ALTERED PATTERNS OF URINARY ELIMINATION, DISTURBANCE IN BODY IMAGE, POTENTIAL FOR ACTIVITY INTOLERANCE AND ACTIVITY INTOLERANCE”. 2. The developed standardized nursing care plans included the nursing diagnosis, definition, defining characteristics, etiologic or related factors that contribute to the condition, recording pattern, desired outcomes and nursing orders (nursing interventions). 3. The plan was used with hospitalized patients on medical - surgical wards to test for content validity. The patient's satisfaction with the nursing care and nurses' job satisfaction were investigated to evaluate the clinical effects after the use of the standardized nursing care plans. A comparison of patient satisfaction with nursing care before and after the introduction of the standardized nursing care plans showed a statistically significant higher level of satisfaction with the standardized care plans. There was no difference in the level of job satisfaction expressed by the nursing staff before and after the standardized nursing care plans were introduced. However, when opinions about the use of the standardized nursing care plans were examined it was found that there was a positive effect on clarity in defining the nursing problems, determining nursing cost, more feasible goal setting, effective and systematic nursing records and indications for nursing research. The results of this study suggest that in order to increase the use of nursing diagnoses in the clinical area, it would be effective to select some wards as a pilot project, give the nurses training in the use of nursing diagnosis and develop and use the standardized nursing care plans. In addition to the ten diagnosis used in this study it is recommended that continual development of nursing diagnoses be done using diagnoses that are appropriate to Korea and testing them for validity through standardized care plans.

  • The main purpose of this study was to develop and evaluate the effectiveness of the standardized patient method in teaching catherization skills, communication skills and students' learning motivation in undergraduate nursing students. The study employed a quasi-experimental method using a non-equivalent control group post-test design. Data were collected over 2 years from August 2000 to September 2001 with 75 sophomore student nurses in one baccaleureate program. The results are summarized as follows ; The scores in catheterization skills and communication skills were statistically significantly higher in the experimental group than the control group. Learning motivation score were also statistically significantly higher in the experimental group than the control group. In conclusion, this study suggests that a standardized patients managed instruction which emphasize authenticity and contex-tualization is very effective in teaching nursing students, the mastery and application of nursing skills, and the utilizing therapeutic communication skills. It is recommended that more standardized patients cases be developed for wider areas of nursing education and this study be replicated with more students using a longitudinal design.

  • Purpose: The purpose of this study was to develop a standardized education protocol for peritoneal dialysis patients. Methods: First, the demand for education was investigated from the 27 patients on peritoneal dialysis and 16 guardians, and later, the standardized nursing education protocol has been developed through the comprehensive literature review and the critical analysis of the related studies. Contents validity and applicability have been tested through the expert group survey. Results: The standardized peritoneal dialysis nursing education protocol with 9 areas and 20 items has been developed. The content validity for timing and duration, contents, method, and place of education proposed by the protocol were all above than 0.8. In terms of the applicability of the protocol, the experts scored between 4.20 to 4.93 for all items except one. The item on home visit education acquired the lowest applicability score, because there might exist potential restrictions in visiting patient's home. Conclusion: The standardized education protocol developed in this study turned out to be adequate by representing high content validity for all items and the applicability also was high except the item on home visit education. Further researches to test the effects of this education protocol should be done.
