  • This study is to seek methods for optimum management of foodservice system for elementary schools in Korea through surveying and analyzing the current status of the "common-management foodservice system" and certain important factors relating to its operations. For the survey of the current status of the "common-management foodservice system", questionnaires are prepared as against schools adopting "common-management system"("Common Schools") as well as schools adopting "conventional management system" ("Conventional Schools") in Kyungsangbookdo ("Kyungbook") area. The survey items are composed of general items, items concerning tasks of dietitians, items concerning purchasing activities and items concerning level of recognition and job-satisfaction of the dietitians. Total 46 dietitians from Common Schools and 65 dietitians from Conventional Schools in Kyungbook region responded the questionnaires. The results of this study are as follows: 1. Information Concerning Dietitians Average age of the dietitians: 26.6 yrs Ratio of two years or less of experiences as school dietitian: Dietitians from Common Schools: 59.1% Dietitians from Conventional Schools: 50.8% 2. Types of the Foodservice In both schools, rural type are prevalent; however, between urban types and islands types, the ratio of urban types are larger than the ratio of islands types in Conventional Schools, and the opposite is true in Common Schools. 3. Decision of Suppliers The ratio of dietitian's participaion in the decision making reaches only 38.3%, indicating the possibility of problems in quality control and hygienic aspects of the food supply. 4. Factor Analysis of the Foodservice Duties Food supply and general affairs administration work was carried out very well (4.2), while personnel management and operational improvement work (2.8), nutritional education work (2.3), and information related work were poorly carried out. No significant differences were found between the two types of the foodservice management systems. 5. Job Satisfaction scores of Dietitians Dietitians were more satisfied with the works (50.0), supervision (50.5) and co-workers (46.9) than pay (18.0) and promotion (22.3).

  • The Sign system of nursing home plays an important role when an elderly adapts to new environment and gets on daily life autonomously. Common living spaces are expecially important in maintaining social nature, adequate signage should be installed to aid them in finding their ways. Sign system is a comprehensive system consisted of various factors. In this research, it has been categorized as signage and cueing. Signage includes text and graphic signs, and cueing consists of floor plan configuration and sensual mechanism of visual, auditory, olfactory senses. Using this framework, held investigation and analysis were held in common area(shared living room, shared dining room, toilet) of 14 Korean, 8 Northern European, and 10 Japanese nursing home facilities. The result revealed that even though sign system should work as a combined unit, each factor was planed without relations to each other and did not perform mutually complementary role. Signage was installed too high, without considering the posture of elderly. Korean facilities used abundant and diverse signage compared to other countries. Japanese nursing home preferred cueing method over signage, and those of Northern Europe used plentiful visual cues such as color and ornaments.

  • This study analyzes the characteristic of elementary science-gifted education winner programs in Gifted Education Database (GED) focusing on scientific creativity. For this purpose, an analysis framework to analyze the programs was developed and a total of 840 inquiry activities from 55 winner programs were analyzed according to the analysis framework. The analysis of the results reveal that 'scientific inquiry skill' of the five scientific creativity components was most frequently included in the activities. 'Scientific knowledge content' and 'creative thinking' were also frequently included. However, 'problem solving ability' and 'common factor' were a little included. In the aspects of integration, the integrations between two or three components with five or eight types were frequently found. No integrations were also frequently included although less than the previous categories. The integrations among four with four types or five components were also slightly found. 'Scientific knowledge content', 'scientific inquiry skills', and 'creative thinking' with other components were more frequently found. However, the integrations of 'common factor' or 'problem solving ability' with the other components were less frequently found. Educational implications of these findings are discussed.

  • Purpose: Failure Mode and Effect Analysis (FMEA) is a widely utilized technique to measure product reliability by identifying potential failure modes. Even though FMEA techniques have been studied, the form of Risk Priority Number (RPN) used to evaluate risk priority in FMEA is still questionable because of its shortcomings. In this study, we suggest common RPN(cRPN) to resolve shortcomings of the traditional RPN and show the extensibility of cRPN. Methods: We suggest cRPN which is based on Cobb-Douglas production function, and represent the various application on weighting risk factors, weighted RPN in a mathematical way, and show the possibility of statistical approach. We also conduct numerical study to examine the difference of the traditional RPN and cRPN as well as the potential application from the analysis on marginal effects of each risk factor. Results: cRPN successfully integrates previously suggested approaches especially on the relative importance of risk factors and weighting RPN. Moreover, we analyze the effect of corrective actions in terms of econometric analysis using cRPN. Since cRPN is rely on the reliable mathematical model, there would be numerous applications using cRPN such as smart factory based on A.I. techniques. Conclusion: We propose a reliable mathematical model of RPN based on Cobb-Douglas production function. Our suggested model, cRPN, resolves various shortcomings such as consideration of the relative importance, the effect of combinations among risk factors. In addition, by adopting a reliable mathematical model, quantitative approaches are expected to be applied using cRPN. We find that cRPN can be utilized to the field of industry because it is able to be applied without modifying the entire systems or the conventional actions.
