The purpose of this study was to evaluate the performance and importance of dietitians' role in order to provide basic information for an efficient foodservice management. This approach was achieved using a variety of quantitative and qualitative informations including general foodservice management, dietitian's role performance and importance. A survey of 453 office and factory foodservices was undertaken and detailed information was collected. Statistical analysis of data was performed using SAS package program for descriptive analysis, 1-test, $\chi$$^2$ test, and analysis of variance. The general characteristics of the dietitians were that 80.20% were aged between 20∼29 and 66.49 had work experience with less than 5 years. And 61.68% were graduated from college. The Importance-Performance Analysis (IPA) technique was used for obtaining information of dietitian's foodservice management practices. By the results of the IPA technique, foodservice attributes with fair to poor performance and high impotance was service management for customer satisfaction. The average scores of dietitian's role performance and importance were 3.33 and 4.03 out of 5, respectively. Dietitians with work experience more than 10 years and aged more than 30 years old had more work performance than those.

Recently, studies have been actively conducted on seismic design and improvement of the seismic performance of bridges, buildings, factories, and plants. In particular, heavy items that are being manufactured or waiting to be shipped from factories (such as generators, engines, and boilers) must be equipped with seismic stoppers to prevent them from moving or falling during an earthquake. Seismic stoppers should be suitably determined by the size and weight of these heavy items; however, they have no general design standard. In this study, structural analyses and seismic tests were conducted to evaluate the performance of newly designed seismic stoppers. Structural analysis was performed on three stopper models to estimate the external load at which the yield stress of the material was not exceeded. Based on the analysis results, a seismic test of the stopper was carried out in accordance with the AC156 test method. Finally, product specifications for all three seismic stopper models were determined and their static/dynamic load performance was evaluated.

Performance analysis and test of a 50kW micro gas turbine is carried out. The present study was initiated in 1996 by KIMM researchers to develope a 50kW class turbogenerator gas turbine engine for hybrid vehicle propulsion system. but with its low emission and compactness, it seemed that it can also be applied as a source of distributed power generation. In this study, general description of the KIMM's efforts to acquire performance test skills of the self-made 50kW micro gas turbine engine. At present, non-load performance test up to 615000 rpm was accomplished and is expected to make through 80,000 rpm by the end of year. Several revisions in design and manufacture were made during the course of experiments. The resulting outputs is thought to be valuable for the further refinement of the system for eventual commercialization of the product.

The work plate in a construction sites is a frequent cause of falling. But the bulk of the work plates lent to the construction site are handled carelessly by workers. There is general concern about performance declining by repetitive use. However, there is not a accurate guide, research and study on reuse work plate. This study was conducted in order to judge the classification guide to reuse work plate and measure the performance of classified reuse work plates. It is the result that even the A-grade plates classified to be in good shape by workers are below the performance standard. This means that the guide and classification are ineffective.

The government is encouraging the notice of obligatory reclaimed asphalt as a result of the economic and social positioning of green growth to reduce the amount of waste resources and to solve natural resource problems by recycling continuously generated waste resources. However, it is necessary to develop application guideline for each application to apply reclaimed asphalt to the site because quality control of the reclaimed asphalt is difficult and the specifications are ambiguous as well. Therefore, in this study, the mix design, quality test, performance test, and finite element analysis about reclaimed Asphalt Pavement were conducted to develop application guideline for reclaimed hot asphalt. The mix design was carried out for the comparative general hot mix asphalt mixture, the reclaimed hot mix asphalt mixture using the additive, and the reclaimed hot mix asphalt mixture without the additive. Indirect tensile strength and tensile strength ratio tests were used to characterize the reclaimed hot mix asphalt mixture. Using the results of dynamic modulus test and FWD test for KPRP analysis and finite element analysis, the performance life was evaluated for general pavement and pavement using recycled aggregate. Finally, the life cycle cost analysis was used to compare and analyze the economics of reclaimed asphalt concrete pavement.

This study evaluated the recycling potential of in-site waste soil as pile back filling material (PBFM). We performed experiments to check workability, segregation resistance, bond strength, direct shear stress test, and dynamic load test using in-site waste soil in coastal areas. We found that PBFM showed better performance than general cement paste in terms of workability, segregation resistance, and bond strength. On the other hand, the structural performance of PBFM was slightly lower than that of general cement paste due to the skin friction force of pile by Pile Driving Analyzer and direct shear stress. However, because this type of performance degradation in terms of structure can be improved through the use of piles with larger diameter or by changing the type of pile, considering the economics and environment, we considered that recycling of PBFM has sufficient value.
