The purposes of this study were to identify the evaluation categories, areas, attributes of the hospital food service and to define the relative importance of the evaluation categories, areas, attributes of the hospital food service using analytic hierarchy process. A survey was conducted from January 8th to 25th in 2007. Questionnaires were mailed to the 310 directors of dietetic departments of hospitals that included 160 primary hospitals, 107 secondary hospitals, and 43 tertiary hospitals. The result of the analytic hierarchy process indicated that relative importance of evaluation category was 0.5259 for food service management and 0.3407 for nutrition care. The food service management consisted of four subcategories, which are equipment standard, sanitation, production, and delivery service. Sanitation(relative importance: 0.2652) was the most important area among the subcategories and it was followed by equipment standard(0.2067), delivery service(0.1864) and production(0.1848). The nutrition care has two subcategories, menu management and meal management. The relative importance of menu management(0.4174) was higher than that of meal management(0.3555). The quality of food service and nutrition care to inpatients can be improved by the evaluation system based on appropriate applications of the developed evaluation indicators for hospital food service systems.

The purpose of this study was to assess an alternative method to characterize indoor environmental factors by multiple indoor and outdoor measurements. Using a mass balance model and regression analysis, penetration factor and source strength factor were calculated using multiple indoor and outdoor measurements. This study was performed in 30 selected apartments in Seoul, Asan, and Daegu area which were constructed within 4 years and over 4 years, to measure the concentration of NO₂ from July, 2004 to September. The results of this study are as follows. The average concentration of NO₂ in Seoul, Asan, and Daegu area in the apartment constructed within 4 years are nitrogen dioxide 48.01㎍/m³ and in the apartment over 4 years are nitrogen dioxide 46.54㎍/m³. Mean ratios of indoor to outdoor NO₂ concentrations are Seoul 0.99, Asan 0.83, Daegu 1.18. The deposition constant and the source strength of NO₂ were 0.97±0.55 hr-1 and 16.33±12.30 ppb/h, respectively. In conclusion, indoor environmental factors were effectively characterized by this method using multiple indoor and outdoor measurements.

The efficient safety estimation for a business should analyze an accident data by considering every possible and potential factor. Thus, we consider several factors to build the safety estimation model to meet fairness and rationality. This paper present the yearly statistic data of accident from KOSHA analyze the data by industry, scale, year of service of a employee, age and other factors; build the safety estimation model for the business based on the accident report derived the analysis. The estimation model is established by the weights for accident type, degree, scale, industry, year of service, and age of the employee derived from AHP(Analytic Hierarchy Process).

Performance management is very popular in business area and seems to be an exciting topic. Despite significant research efforts and myriads of performance metrics, performance management today as a rigorous approach is still in an immature state and metri

The unsafe act and unsafe condition is due to human error that experience 80% of safety one of the most important issues to reduce industrial accidents as a whole, is how to reduce the accident rate by the human error Therefore, this paper describes the d

The risk assessment for heavy metal pollutions were analyzed by using statistical techniques including correlation and cluster analyses. The contamination data in this investigation obtained were from the Chungcheongnam-do abandoned mines. The descriptive statistical analysis showed that the values of Pb and Zn were relatively higher than other heavy metal values. The detection of heavy metals by distance from abandoned mines within 1,000m were mostly As, Cd, Pb, and Zn. It was noted, especially, that Zn was even detected at 4,000m The results of coefficient correlation showed that Zn to Cd was the highest values. The cluster and dendogram analyses were generated. The results showed the two clear groups by heavy metal characteristics.

National R&D programs play an important role in the development of a country in this age of the knowledge economy. Since many numbers of R&D programs compete for limited resources such as national R&D budget, the R&D program evaluation problem is a challe

Nowaday mobile phone is an essential item for convenient daily life. Mobile phone enables us to obtain a lot of necessary and important things such as communication, information, leisure and entertainment. As the technology of mobile phone has been developed, the function of mobile phone can be compared to small computer. Customer's need of mobile phone has been varied and changed according to individual taste and preference. The main purpose of this research is to analyze priority of mobile phone brands using evaluation method of intangible assets with five major brands.

In this study, with the objects of 173 institutions of university and research institutions, investigation was carried out through visit investigation ar d questionnaire investigation. Frequency and severity of occurrences was acquired mainly through universities and research institutions which have reported occurrences of accidents to the Ministry of Education, Science, and Technology. Quantitative danger evaluation was conducted through frequency and strength of occurrences. Case study was carried out by selecting bio science laboratory of university and as the result of this study, degree of danger among the inspection objects of bio science laboratories, laboratory work place was evaluated as the most dangerous with the scores of 155.00 and as the result of average danger level, compression gas cylinder was evaluated as the most dangerous with the scores of 6.4000.

As The development and commercialization of advanced technologies will depend increasingly on efficient technology transfer and technology trading systems and the knowledge economics grows rapidly, the value of intangible assets is more emphasized in business nowadays. Intangible assets include intellectual capital and intellectual property. This requires the development of technology markets or exchanges and hence a reliable technology valuation methodology. Our focus is on the business aspects of technology' contribution and we propose an objective scoring system, which is implemented by ANP, for Technology valuation of enterprise. As a result, This study intends to evaluate the contribution of an individual technology in intangible assets by the Analytic Network Process(ANP).
