The purpose of the study was to investigate relationships among food safety training, knowledge, and practices of school food service employees. A questionnaire that identified employees' food safety training experience, knowledge, and practices was developed based on a review of literature. A total of 341 Korean school food service employees participated in the survey; the final usable responses were 293 (a response rate: 86%). Statistical analyses were conducted using SPSS for Windows (version 10). Most of the respondents (> 86%) took training sessions on 'proper hand washing' and 'proper food storage temperatures', whereas less than 60% had training on 'monitoring procedures and corrective actions at critical control points'. The mean score of their food safety knowledge was 8.02 out of 11. The majority of the employees knew correctly 'potentially hazardous foods (93.2%)' and 'diseases and symptoms with which they are excluded from working (87.0%)'; less than 50% chose a correct answer for 'sanitizing food contact surfaces.' A chi-square analysis revealed that the employees' actual knowledge did not differ significantly by whether they had food safety training (at the level of a =0.01), except one topic 'diseases and symptoms with which they are excluded from working.' Their self-reported practice scores were rated as 2.98 - 3.39 based on a 5-point Likert-type scale (1-not at all, 5-always). Employees' food safety training should be conducted continuously and repetitively to improve the effectiveness of the training.

The purpose of this study is to understand the present housing condition of the suburban housing complex, and the residents' preferences to make their living condition better in Yong-in and Yang-pyeong, Pocheon, Kwang-ju and Kimpo in Kyung-Ki province, Korea. Questionnaire survey has been carried out to figure out the current status and residents' preferences of the Suburban housing complexes (hereafter SHC). The study showed the present status and the demands of people for their houses as a result like the below. First, currently the SHCs are managed by a joint control type, and the preferences of the residents' showed the similar way. Because of this status, the SHC planning is supposed to have the self-governing management and community space to support the activity of their community. Second, most SHCs doesn't have many public facility, in contrast, each house has various exteriors. This result shows the residents want more to develop their own houses' exterior than that of the SHC's public facility. Prior to plan the SHC, a program should be considered to give better understanding to residens what is the complexed life and make them choose what they really want to have. Third, the studied SHCs' renovation activities are commonly focussed on the exteriors. This shows the residents' life style is focussed more on the out-door life. The planning for the future SHC is supposed to have the points that could follow up the out-door friendly situations.
