The purposes of this study were to analyze the quality attributes and customer satisfaction in school foodservice by distribution place and to suggest an improvement plan. The survey was distributed to different respondents (students, parents, and faculty) at different types of schools (elementary school, middle school, and high school) on September 2008 in 16 cities and provinces. The statistics were analyzed using descriptive analysis, t-test, and ANOVA by SPSS 12.0. All foodservice quality attributes were significant different by school type and the students in elementary schools had higher scores than students in middle and high school. A comparison of scores by school type and distribution place demonstrated that elementary schools had a higher score for quality attributes and in middle and high school dining halls had a higher score for quality attributes. The overall customer satisfaction with school foodservice was higher for dining halls than classrooms for all respondents (students, parents, and faculty). For students, the overall customer satisfaction score was 69.1 for schools using dining halls and 66.4 for schools using classrooms. The overall customer satisfaction for classrooms was higher in elementary school but, this score for middle and high school was higher for dining halls. Therefore, students prefer dining halls to classrooms. Especially, as the students grow, they have an increased preference for dining halls.

Purpose: The objective of this study was to analyze the effects of medical staffing level as bed-to-medical staff ratio on patient outcomes as length of stay (LOS) among hospitals in Korea. Methods: Two hundred and fifty one hospitals participated in the study between January and March 2008. Data for the study was requested by an electronic data interchange from the Health Insurance Review Agency in 2008. In data analysis, SPSS WIN 15.0 program was utilized for descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Results: The mean score for length of stay was 13.6 days. The mean of operating bed-to-nurse ratio was 7.93:1. The predicting factors for LOS were bed-to-nurse's aide ratio, bed-to doctor's ratio, severely ill patient rate, and hospital type. These factors explained 28.9% of the variance in patient outcomes. Conclusion: This study results indicate that the relationship between medical staffing level and patient outcomes is important in the improvement of the quality of patient care. Thus, improvements in the quality of the nurse practice environment could improve patient outcomes for hospitalized patients.

Quality assurance in high level education is one of the most important problems in Korea, and around the world. Many studies have examined means of assuring the quality of education, mostly focusing on what type of graduate we should launch into the real world. However, it has been realized only in technical fields, such as Engineering, Medicine, etc. Here, we discuss the problems of Korean high level education in scientific fields, and present some answers from American innovation policies. The USA has changed the idea about how to innovate, and in recent years has developed the Professional Science Master's(PSM) degree, which is now awarded by over 100 American universities. PSM programs have produced graduates who can innovate in scientific fields, e.g., in biology, environmental science, and statistics. The degree is highly praised by the Council On Competitiveness, which consists of CEOs of major corporations, university presidents, and heads of labor organizations. The PSM seems to meet their expectations. Interestingly, many research universities have established PSM programs. We examined the reasons why many American universities have accepted the PSM despite their daily duties for research and doctoral education. Finally, we discuss the possibility that programs such as the PSM can succeed in Korean universities.

Polycrystalline diamond is an ideal material for parts with micro-holes and has been widely used as dies and cutting tools in automotive, aerospace and woodworking industries due to its superior wear and corrosion resistance. In this research paper, the modeling and simultaneous optimization of multiple performance characteristics such as material removal rate and surface roughness of polycrystalline diamond (PCD) with ultrasonic machining process has been presented. The fuzzy logic and taguchi's quality loss function has been used. In recent years, fuzzy logic has been used in manufacturing engineering for modeling and monitoring. Also the effect of controllable machining parameters like type of abrasive slurry, their size and concentration, nature of tool material and the power rating of the machine has been determined by applying the single objective and multi-objective optimization techniques. The analysis of results has been done using the MATLAB 7.5 software and results obtained are validated by conducting the confirmation experiments. The results show the considerable improvement in S/N ratio as compared to initial cutting conditions. The surface roughness of machined surface has been measured by using the Perthometer (M4Pi, Mahr Germany).

Purpose: Objective of this study was to investigate how often nurses to perform patient safety activities. Methods: 521 observations were collected in 9 hospitals by 107 nursing students. Nurses' patient safety care activities were measured 0 (not at all) to 10 (all the time) scores. Descriptive statistics, independent t-test, one way ANOVA, correlation, multiple regression used to analyse data. Results: Items like 'Initial nursing assessment', 'drug management bring on', 'preparation for radiology test', 'falls assessment', 'nursing record' got high scores. But, scores of 'patient identification', 'verbal order management', 'hand hygiene' were lower than others. Each scores were different significantly according to institutions and departments. Within a same institution, the variance of scores, especially in 'patient identification', 'hand hygiene' were great. Scores of activities were different according to characteristics of institutions like type, location, number of beds, teaching hospital, number of accreditation, JCI accreditation. Predictors influencing nurses' patient safety activities were type, location and accreditation. These predictors account for 19.4% of variance. Conclusion: Performance of nurses' patient safety activities were different significantly according to characteristics of institutions. The important items like 'patient identification', 'hand hygiene' had achieved lowest performance. Further researches are needed to improve the basic safety activities.
