This study investigated faculty perceptions of the improvement and effort for achievement of the quality of nursing education through accreditation in baccalaureate nursing programs in 2006. Survey data from 190 professors of 33 accredited nursing schools were statistically analyzed using SPSS ver. 19.0 software with descriptive statistics, t-tests, and ANOVA. Through accreditation, about two-thirds of subjects perceived that the quality of education had 'improved' and the purposes of the accreditation were moderately successfully achieved (score 3.50). They also perceived their schools made a strong attempt (score 4.24) to assure quality. The perception scores of efforts to assure the quality of education varied significantly according to the characteristics of the subjects, the existence of a university hospital, the type of college, and the year of school founding. There were significant differences between the level of improvement in education and the extent of effort to assure the quality of education. Accreditation contributed to improved quality of nursing education except for some issues which need more consideration. To maintain high quality, the accreditation of baccalaureate nursing programs should be performed with continuity and on a regular basis.

As interests in the quality of data in database systems are growing recently, analysis and improvement of data quality in databases have been an important issue. However, there has yet to be a clear agreement on how to reasonably calculate the total cost of such project. In this paper, based on real project data and budget statistics, we develop a model to estimate the cost for quality analysis and improvement project of a database. We first conduct statistical analysis to build our basic model. Throughout this analysis, we have identified factors that determine the scale of works required to conduct the project and eventually determine the cost. In addition, we have identified factors that determine the complexity of the project. These factors can adjusts the cost determined by the scale of works. Our model is verified and improved by surveys on experts. We apply our model to newly conducted projects and observe that our model estimates the cost of each project reasonably well.

This study investigated factors affecting care for elderly patients, management of systemic disease, infection management, improvement of medical care quality, and educational requirements, and provide basic data for quality care for elderly patients with systemic diseases. An online survey was conducted among dental hygienists working at dental institutions and data of 172 individuals were analyzed using the SPSS 21.0 program. Descriptive statistics was performed for general characteristics. For factor analysis by general characteristics, t-test and ANOVA were performed. For differences between groups Scheffe verification was performed. A correlation analysis between factors was performed using Pearson's correlation analysis, and a factor analysis affecting the improvement of healthcare quality was performed using multiple linear regression analysis. Care for elderly patients was 52.33/75, management of systemic disease was 12.65/17, and infection management was 96.92/130. Improvement of medical quality (institutional effort) was 22.87/35, and improvement of medical quality (personal effort) was 22.72/35. The most common educational needs were "necessary". Analysis revealed a positive correlation between factors.. Factors affecting improvement of medical quality (personal effort) were age, final academic background, place of work, and the presence or absence of annual medical examinations. The findings of this study indicate that there is a significant correlation between factors. For the qualitative care of elderly patients, education programs related to elderly characteristics, systemic diseases, and infection management should be actively conducted by dental hygienists, and interest and research on geriatric dental hygiene is needed, centering on associations and educational institutions.

Purpose: The purpose of this study is to analyze the score data released by the Korea Institute of Curriculum and Evaluation to find out the problems with the current scoring system provided by the College Scholastic Ability Test and to suggest improvement measures to solve these problems. Methods: We calculated the descriptive statistics of the standard scores using the frequency distribution table of the standard scores and identified the characteristics of the standard scores by expressing the distribution as a graph. Also, we developed an index to evaluate whether each stanine level was stably assigned and calculated the indexes for each area/subject by using the data on the number of examinees for each level. Results: We found that the relationship of conversion from raw scores to integerized standard scores is different depending on the size of the standard deviation of the raw scores, and identified the problem that the raw score information is not fairly reflected in the calculation of the percentile and level as the two raw scores are converted to one standard score. This problem can be solved by calculating the standard score to a decimal point. Conclusion: In this study, as a way to improve the quality of the scores of the current CSAT, the standard score and percentile decimal notation, the specific regulations of the standard score and stanine level calculation method, and the expansion of the open range of the scores were suggested.

It is well known that vital statistics is of great importance as basic data for establishing various range of national policies. Especially, vital statistics is important among demographic information for monitoring and evaluating the population policy, for constructing life table, for making population projection, and for studying various aspects of the society. In principle, the production of vital statistics is based on the registration system. It is, however, still observed that there are some limitations in utilizing fully the registration system due to the inherent problems such as problems in its coverage, accuracies and timeliness. Thus, as an alternative, many countries conduct survey on vital statistics in order to supplement the registration system and obtain in-depth data. Korea is no exception in this aspect. The National Bureau of Statistics carries out the so-called Continuous Demographic Survey. This is a kind of multi-round retrospective survey, covering 32, 000 households and having reference period of one month. The survey has also characteristics of multi-subject sample. Thus, surveys on economic activity status of population, house-hold income & expenditure, and social indicators are together conducted with the same sample. It is, however, found that the survey itself tends to have some quality problems. Especially, the quality problems connected with field data collection are summarized as coverage error, non-response error and response error. Although it is inevitable not to be free from these errors, we should make all our efforts to reduce the errors. The probable schemes pointed out in this paper are as follows : 1) the strengthening formal quality control activities, 2) the review of the survey method, i. e., the combining interview method with mail-sending and mail-back method or pick-up method, 3) well documentation for various cases found in every stage of data collection, and 4) the strengthening the analytical activities. It is, also, emphasized that sincerity of planners and interviewers is the most important factor among other things.

Some optimal designs and data analysis methods based on a Gaussian spatial linear model for computer simulation experiments are considered. For designs of computer experiments, Latin-hypercube designs and some optimal designs are combined. A two-stage computational (2-points exchange and Newton-type) algorithm for finding the optimal Latin-hypercube design is presented. The spatial prediction model which was discussed by Sacks, Welch, Mitchell and Wynn(1989) for computer experiments, is used for analysis of the simulated data. Moreover, a method of contructing sequential (optimal) Latin-hypercube designs is considered. An application of this approach to the quality improvement and optimization of the integrated circuit design via the main-effects plot and the sequential experimental strategy is presented.

The Ministry of Transportation forecasts that the total number of automobiles in use in 1997 will be increased to about 10 million units. Until now, with the increase of domestic demand for automobiles, the customers' complaints have been raised frequently in relation with insufficient supply of auto parts for the repair and maintenance. At the same time, the industry came to face with new problems such as customers' requests of auto makers' quality services. Until now there were not any statistics on the registration of car age for each car type. So, for the auto makers' efficient aftersales management a system for collecting registration statistics was developed, and it has attributed remarkably to the improvement of the aftersales services, through easy anticipation of the requirements of parts being used for not only the small-produced but the massproduced car types. And a systematic instrument useful for auto industry, transportation and policy on environment is provided by timely supply of various statistics to the industry.
