Effective and systematic sanitation management programs are necessary to prevent foodborne disease outbreaks in school foodservice operations. The purpose of this study was to identify the elements to improve in order to ensure the safety of school food service by evaluating sanitation management practices implemented under HACCP-based programs. The survey was designed to assess the level of hygiene practices of school food service by using an inspection checklist of food hygiene and safety. Fifty-four school foodservice establishments considered as poor sanitation practice groups from two year inspections by Seoul Metropolitan Office of Education were surveyed from September to December in 2005. Inspection checklists consisted of seven categories with 50 checkpoints; facilities and equipment management, personal hygiene, ingredient control, process control, environmental sanitation management, HACCP system and safety management. Surveyed schools scored $68.0{\pm}12.42$ points out of 100 on average. The average score (% of compliance) of each field was 10.7/20 (53.3%) for facilities and equipment management, 7.4/11 (67.2%) for personal hygiene, 7.4/11 (74.1%) for ingredient control, 22.4/32 (69.8%) for process control, 8.9/12 (73.8%) for environmental sanitation management, 4.2/7 (59.7%) for HACCP systems management, and 7.2/8 (89.7%) for safety management, respectively. The field to be improved first was the sanitation control of facilities and equipment. The elements to improve this category were unprofessional consultation for kitchen layout, improper compartment of the kitchen area, lacks of pest control, inadequate water supply, poor ventilation system, and insufficient hand-washing facilities. To elevate the overall performance level of sanitation management, prerequisite programs prior to HACCP plan implementation should be stressed on the school officials, specifically principals, for the integration of the system.

In this paper we deal with a design of the evaluation system to assess the vehicle operational control algorithm for Personal Rapid Transit(PRT) system. PRT system is different from the conventional rail traffic system in such that the station is off-line so as to guarantee a very short headway. In this study we propose an evaluation system to assess the performance of the proposed vehicle control algorithm. The evaluation system is composed of virtual vehicles, central control system, virtual wayside facilities, monitoring equipments. The virtual vehicles are made up by the laptop computers and the central control system employs Power PC process of Motorola Inc. The wayside facilities are implemented by employing the PXI module of the National Instruments Corporation. In order to test the proposed evaluation system a test algorithm is used, which has been simulated in the combined simulation system between Labview Simulation Interface Toolkit and Matlab/Simulink.

In this study, a smart isolation platform has been developed for control of microvibration of high-technology facilities, such as semi-conductor plants and TFT-LCD plants. Previously, microvibration control performance of a smart base isolation system has been investigated. This study compared microvibration control performance of a smart isolation platform with that of conventional base isolation and fixed base. For this purpose, train-induced ground acceleration is used for time history analysis. An MR damper was used to compose a smart isolation platform. A fuzzy logic controller was used as a control algorithm and it was optimized by a multi-objective genetic algorithm. Numerical analysis shows that a smart isolation platform can effectively control microvibration of a high-technology facility subjected to train-induced excitation compared with other models.

Recent public concern about air pollution caused by swine production facilities has forced to develop the methods to reduce and control the swine odors. Swine odors were affected the life of pig farm neighborhoods, swine productivity, pig health, diseases, and human right, safety, sanity as negatively. The first approaches of control of swine odors are the change or improve of the classical management systems, which are manure treatment method, manure storage facility, phase feeding, sex-divided feeding, feeder type, liquid-slurry feeding, environment control of swine building and dust control of indoor swine facility. The methods to control odor emission from manure have to include the diet modification as nutritional basis. In recent, research emphasis has focused on manipulating the swine diet to increase the nutrient utilization of the diet to reduce excretion products and reduction of odors. There are lots of feed additives and pit additives introduced as practical basis for reducing odor emissions. The ozone treatment method is candidate as the good system for reducing swine odor. But this system is still too expensive to practice in present.

Purpose: With the increasing of public-use facilities, there has been a growing concern over Indoor Air Quality(IAQ) of public-use facilities. Because the facilities are easy to be exposed to indoor air pollutants, they needs to be periodically managed the IAQ. Methods: In this study, indoor air pollutant concentrations of 24 vulnerable facilities were measured and compared. The measurements were conducted for pollutants which are defined in 'IAQ Control In Public-Use Facilities, etc. Act'. We took two measurements, the first was carried out in summer and the second was proceeded in winter. We analyzed the values according to the type of facilities and pollutants. Results: There was a difference in pollutant concentrations by the season and in occurrence characteristics by the measurement spot. Therefore, we need to manage pollutant concentrations by characteristics of occurrence. Implications: Based on the comparative analysis of pollutant concentrations, we suggested cause and improvement strategies for IAQ management of Vulnerable facilities.

We present following research summary and implications through the analysis of the research. First, the before the opening of public cremation facilities compared to new opening of those, the number of the corpse cremation increases to annual average of 5.5% of the rate, and it has a positive effect on increasing rate of the cremation. Therefore, a policy of expanding the supply of public cremation facilities should be pursued to improve cremation rate in the area of uninstalled public cremation facilities. Second, the before the opening of public cremation facilities compared to new opening of those, the number of the corpse cremation has increased to the annual average 3,623 people(56.9%) at jurisdiction area, while it has decreased to 949 people (28.3%) at the out of the jurisdiction area. The active efforts and building the funding expansion should be made to establish public cremation facilities of the central and local governments to improve convenience of the use of public cremation facilities. Third, since the before and after opening of public cremation facilities at Jeongeup City lead to great effect on demand of jurisdiction area and out of the jurisdiction area, the cremation demand should be reduced through the supply expansion of public cremation facilities and differentiation strategy to control cremation demand at the out of the jurisdiction area, focusing on metropolitan areas with high cremation demand, such as metropolitan areas or metropolitan cities.
