The Certification system will be able to expect that effect of marketing and the corporate image rising, if the certification body guarantees the contents of certification against industrial technical advance and safety, environment and efficiency, quality when it is suitable in the standard which is provided. The certification system where the private organization operates but recently on the legal notarization outside is disordering and the trust regarding the certification falls and the objective and gist of origin are damaged. But recently the trust of certification has fallen and the objective and gist of origin are damaged. Because the non-government certifications are disordering. Also the damage of the consumers majority occurs but it is insufficient the investigation analysis against the present condition regarding a non-government certification system and the operation actual condition. So it is necessary the actual condition where the countermeasure against hereupon is urgent. In this study, we present the operation direction of efficient against non-government certification system through investigation and the analysis.

This study deals with actual commuting distance and influence of risk factors depending on commuting distance and mode in order to reestablish actual commuting zone of primary school students. Data mining analysis(CHAID) was applied for this reestablishment using survey results from 6,927 primary school students in Seoul Metro. Six risk factors; convenience level of commuting path condition, convenience level of road crossing condition, vehicle speed on commuting path, segregation level between commuter and vehicle, congestion level of commuting path, and public security level and two mode; walking and cycle are considered in the analysis. As the results of CHAID analysis, commuting distance was divided into four zones; Internal Zone(0.491km under), External Zone(0.492 ~ 1.492km, 1.493 ~ 2.699km), Commutable Zone(2.70km over), and awareness level on safety is declined as commuting distance is increased. The risk factor affecting on safety is recognized differently by students depending on commuting distance and mode. For students commuting by walking, vehicle speed on commuting path and convenience level of commuting path condition are recognized as the prime risk factor within Internal Zone and Commutable Zone, respectively. For students commuting by cycle, convenience level of road crossing condition and vehicle speed on commuting path are recognized as the prime risk factor within Commutable Zone. Analysis results show that improved plan and program for commuting path for primary school students are required considering actual commuting distance and method.
