obtain such data, significant difference in the quality and quantity of relevant data exists, thus rendering individual credit rating difficult. However, credit information is a data concerning personal identification information and objective facts arising from financial transaction processes, thus there is no reason for differently treating migrants in that matter and it is institutionally and practically possible to collect, provide and utilize credit information of migrants, so it is possible to deliberate and determine whether the migrant is eligible for the mortgage insurance based on individual credit grades. The Commission concluded that, nevertheless, unilaterally excluding migrants from those eligible for the mortgage insurance is discrimination without reasonable cause and recommended to the insurance company to revise the relevant business regulations ensuring non-exclusion of migrants from eligibility of the mortgage insurance on the ground of foreign nationality and the accused accepted the recommendation and modified relevant business regulations. 6) Discrimination Based on Appearance and Physical Attributes Discrimination based on physical attributes, including appearance, refers to unfair treatment without reasonable cause based on physical attributes, conditions or capacities etc., such as facial appearance, external appearance, physical strength, height, weight, agility and cardio-vascular capacity. ○ Discrimination in Admission to Pilot Training Institutions Based on Visual Ratings Three persons, including Mr. Lee, were candidates to become aircraft pilots. They alleged that according to the current Enforcement Decree of the Aviation Act, vision requirements for issuing class 1 pilot license allowing to fly aircraft are "corrective vision through spectacles is 1.0 or higher and naked vision is 0.1 more higher" or "if naked vision is 0.1 or less, one should submit close optimal examination result." However, admission requirements of aeronautical science and flight operation department or aeronautical science and logistics department require candidates to have naked vision of 0.4-0.5, Chapter 4.
