Purpose: The purpose of this study was to describe the life experience and explore the essence of meaning among mothers-in-law of multi-cultural families in Connam area, Korea. Methods: The study subjects were 9 mothers-in-law of multi-cultural families who are living with foreign daughters-in-law in Chonnam area. The data were collected through focus group interview from July 2009 to August 2010, using open questionnaire. The data were analyzed by the method suggested by Morgan and Kruger (1998). Results: In this study, the following categories were extracted: 1) Relieved feeling, 2) Conflicts from being different, 3) Being patient, 4) Accepting as my daughter-in-law, 5) Imagining happy future of my son. Conclusion: The study shows that subjects experience both negative and positive psychological feelings. Therefore, it is needed to reduce negative factors and improve positive factors that they experience in life with foreign daughters-in-law and to provide consultation and education to mothers-in-law of multi-cultural families.

The purpose of this study was to evaluate and compare the effectiveness of various low-viscosity resin systems used as rebonding agents to prevent microleakage at the margins of class I composite resin restorations. Seventy sound human premolars were selected for experiment. Class I cavities were prepared and each cavity was conditioned with a 37% phosphoric acid for 15 sec, rinsed with water for 15 sec, and dried with compressed air. Bonding agent(Scotchbond Multipurpose, 3M Co.) was applied and a hybrid composite resin (Z-100, 3M Co.) was placed using an incremental technic. The excess cured composite resin was carefully removed with Sof-Lex discs(3M Co.) to expose the original margins of the cavity. The following seven groups were established : group 1 was not rebonded and used as control group ; group 2 was rebonded with a Scotchbond Multipurpose(3M Co.) and finished ; group 3 was rebonded with a Fortify(BISCO) and finished ; group 4 was rebonded with a Concise white sealant(3M Co.) and finished ; group 5 was rebonded with a Concise white sealant(3M Co.) and not finished ; group 6 was rebonded with a P&F sealant(BISCO) and finished; group 7 was rebonded with a P&F sealant(BISCO) and not finished. The specimens were then subjected to 500 thermocycles between 5 & 65 with a 10 see dwell time and immersed in 2% methylene blue dye solution for 24 hours and sectioned with low-speed diamond cutter into two part under water condition. The extent of microleakage at rebonded margins was evaluated microscopically and scored for dye penetration according to the following scale : 0=no dye penetration ; 1=dye penetration to half-way along axial wall between enamel surface and DEJ ; 2=dye penetration beyond halfway along axial wall between enamel surface and DEJ ; 3=dye penetration to the full depth of DEJ or beyond DEJ. Selected samples were prepared for SEM observation to determine the depth of penetration of the rebonding agent into the marginal interface. The obtained results were as follows: 1. In the group 2 and 3, which is rebonded with a Scotchbond Multipupose and Fortify, dye penetration score were decreased significantly than that of group 1 (P<0.05), but group 4 and 6 were not statistically different from group 1(P>0.05). 2. There were significant differences between group 4, 6 and group 5, 7 when compared by dye penetration score (P<0.05). 3. In the SEM observation, Scotchbond Multipurpose and Fortify were penetrated within $30-40{\mu}m$ depth of the outermost surface. However, both sealants were failed to penetrate into the debonded interface.

This study was to evaluate shear bond strength fluoride-relesing sealant and nonfluoride-relesing sealant to enamel surface of bovine tooth. 80 extracted bovine teeth were randomly assigned to four groups,and four kind of sealants including Teethmate-A(Kuraray Co.),Teethmate-F(Kuraray Co.),Helioseal(Vivadent Co.),Helioseal-F(Vivadent Co.) were bonded to exposed enamel surfaces using silicon plate. Shear bond strength was determined in an instron universal testing machine at a crosshead speed of 1mm/min.Then,the fracture surfaces of test specimens were investigated with scanning electron microscope. The obtained results were as follows; 1.The shear bond strength decreased in the following oder:Teethmate-A(18.31MPa),Teethmate-F(11.90MPa),Helioseal(11.74MPa),Helioseal-F(10.64MPa). 2.The shear bond strength of Teethmate-A showed significantly higher than that of Teethmate-F(P<0.05),but Helioseal and Helioseal-F didn't showed statistically different(P<0.05). 3.According to the SEM,Teethmate-A group showed cohesive failure,and Teethmate-A group & Helioseal group showed mixed pattern of cohesive failure and Helioseal-F group showed adhesive failure.
