The purpose of this study was to examine the level of information literacy of the marriage immigrant gatekeepers in Korea. To do this, 51 gatekeepers who live in Busan and Gyeongnam Province were surveyed and the result was compared with the result of another study that was conducted regarding 189 ordinary marriage immigrants living in Busan and Gyeongnam Province in 2009 and used the same survey instrument. As a result, the level of information literacy of the gatekeepers was superior to that of the ordinary marriage immigrants. Also, 14 gatekeepers were interviewed to investigate how they had higher level of information literacy than that of ordinary marriage immigrants. Through analysis of the interviews, "information use environments of the mother country" didn't support their information literacy, but "higher education level", "Korean language skills and bilingual/multilingual abilities", "experiences of information literacy education", "information-friendly home environment", "positive attitude toward life and active social participation" and "active utilization of several information service providers and media" could be the backgrounds of higher information literacy of the marriage immigrant gatekeepers. At the end of this study, some suggestions are made for improving the information literacy of the ordinary marriage immigrants.

This study aims at contributing to the restorative dentistry by examining results in the vertical load test of four different low invasive fixed partial dentures. Based on a hypothesis on the right upper first molar is missing, three units of FPDs were made for the second premolar and the second molar abutment. that is, twelve metal dies and FPDs were made for resin bonded FPD and Two Key Bridges and Human Bridge without occlusal rest and Human Bridge with occlusal rest. By using universal test machine, the numerical maximum value were recorded during the vertical load test of each FPDs after the bonding process treated by Maxcem which is resin cement. The failure process and its result of prosthesis were also observed. The maximum load was 7,295 N, 4,729 N, 2,190 N, 3,073 N from groups of resin bonded FPD, Two Key Bridge, Human Bridge without occlusal rest and Human Bridge with occlusal rest respectively. There was a statistical significance among the groups of resin bonded FPD, Two Key Bridge and Human Brides. However, there was no significant difference between Human Bridge without occlusal rest and Human Bridge with occlusal rest. Regarding the failure of prosthesis, the groups of Resin Bonded FPD and Two Key Bridge showed that one of the abutment teeth in the both side of retention part was highly failed earlier than the other one (83.2% and 66.6% respectively). While, Human Bridge without occlusal rest and Human Bridge with occlusal rest showed high percentage of failure in the abutment teeth in the both side of retention part at the same time (91.6% and 58.3% respectively). This study demonstrates that the group of Human Bridges has low resistance to the vertical loads of low invasive FPDs in comparison with the groups of resin bonded FPD and Two Key Bridge. Nevertheless, the maximum occlusal load of the restorative position, resistance to diverse restoration failure, amount of tooth reduction and patients' cooperation should be considered when they are applied in the clinic in order to choose an appropriate restoration for each patient.
