This study aims to investigate the mediating effect of career adaptability in the relationship between strengths knowledge and occupational engagement for nursing students. The participants of this study were 284 nursing students in three Universities in G City, J Province. Data analysis used descriptive statistics, t-test, ANOVA, Pearson correlation analysis. Also mediation analysis was performed according to the Baron and Kenny method and Sobel test. The career adaptability showed a partial mediating effect between the strengths knowledge and the occupational engagement(Z=6.66, p<.001). The positive the strengths knowledge(β=.24, p<.001), the higher the career adaptability(β=.49, p<.001), the higher the occupational engagement level, and the explanatory power to explain occupational engagement was 47%. In order to increase the level of career engagement of nursing students, specific behavioral strategies for fostering career adaptability as well as cognitive guidance strategies that enable individuals to recognize their strengths in career-related education and counseling are needed.

The purpose of this study was to explore ways to help improve adolescents' happiness by exploring the influences of emphatic ability and family strengths on happiness. This subjects were 514 middle school students living in Gwangju. Data were collected from self-report questionnaires and analyzed with SPSS 22.0 program. The major findings were as follows; First, the adolescents' emphatic ability('viewpoint', 'identity', 'emphatic interest'), family strengths('family respect and affection', 'role sharing and problem solving', 'communication and bonds', 'financial stability') and happiness scores were higher than the median(3.00). Emphatic ability('viewpoint', 'identity', 'emphatic interest', 'personal suffering') and family strengths('communication and bonds') showed significant difference according to gender. Second, the adolescents' happiness was influenced by 'family respect and affection', 'role sharing and problem solving', 'financial stability', 'personal suffering', 'identity', and 'emphatic interest'. Adolescents' happiness was explained about 39% by these variables. In other words, the higher family respect and affection, both higher role sharing and problem solving and higher financial stability, with lower personal suffering and higher identity and higher emphatic interest showed the higher happiness. These findings demonstrate the emphatic ability and family strengths in adolescents influence on the level of happiness. As such, in order to improve the happiness of adolescents, it is necessary to energize those programs focus on the forming healthy family relationships and to design finance assistance programs that could attempt to minimise financial gap. Additionally, it is necessary to develop programs aimed to enhance emphatic ability and continue such programs in homes as well as at schools. Finally, it is necessary to implement curriculum that may improve family strengths and emphatic ability, which have influenced on the happiness in adolescents. Since the subject "Technology & Home Economics" helps to enhance family strengths, emphatic ability and eventually amplifies the happiness, it is necessary to expand and reinforce it as well as to make it a mandatory subject.

The bond strengths of composite resin to tooth dentin vary with the methods of cavity preparation and surface treatment. Recent developments in techniques of dentinal surface treatment have renewed interest in microabrasive as a means of tooth preparation, The purpose of this study was to determine the effects of a new method of cavity preparation on the bond of composite resin to dentin. Freshly extracted 144 healthy human third molars were used in this study. The dentin surfaces prepared with #600 SiC abrasive paper were divided into control and air abrasion groups according to the method of dentin surface preparation using different combinations of delivery pressure, time, and acid etching. The shear bond strengths were measured after the composite resin (Clearfil Photo Bright) was bonded to prepared dentin surfaces by light-curing using a dentin bonding system (All-bond 2), In addition, the average surface roughness was measured to investigate the effect of differently prepared dentin surfaces on the shear bond strengths. The surface changes of prepared dentin and the debonded dentin surfaces were observed with SEM (S-2300, Hitachi Co., Japan). The following results from this-study were obtained ; 1. There was no significant difference of shear bond strengths according to the changes of delivery pressure and time. 2. The shear bond strengths were lower than the control in the air abraded-only groups, but those of the additional acid-etched groups were higher than the control. 3. The shear bond strengths to all air-abraded surfaces were increased by acid etching. 4. The correlation between shear bond strengths and surface roughness was not certain, although the mean surface roughness of all air-abraded surfaces has increased evidently while it has slightly decreased for additional acid etching. 5. On SEM examination, the dentinal tubules were almost occluded in the air abraded-only groups, but those were opened in the additional acid-etched groups. 6. The debonded surfaces were showed adhesive failure mode in the air abraded- only groups, while those were showed mainly the mixed and cohesive failure mode in the additional acid-etched groups. These results suggest that the layer produced during cavity preparation or surface treatment with air abrasion must be removed for maximum bond strength of composite resin to dentin.

This study aims to investigate the mediating effect of outcome expectation in the relationship between strengths knowledge and career adaptability for nursing students. The participants of this study were 284 nursing students in three Universities in G City, J Province. Data analysis used descriptive statistics, t-test, ANOVA, Pearson correlation analysis. Also mediation analysis was performed according to the Baron and Kenny method and Sobel test.. Career adaptability is positively correlated with strengths knowledge(r=.61, p<.001), outcome expectation(r=.55, p<.001), and strengths knowledge is positively correlated with outcome expectation(r=.41, p<.001). The outcome expectation showed a partial mediating effect between the strengths knowledge and the career adaptability(Z=3.85, p<.001). The positive the strengths knowledge(𝛽=.44, p<.001), the higher the outcome expectation(𝛽=.33, p<.001), the higher the career adaptability level, and the explanatory power to explain career adaptability was 50%. Therefore, in order to improve the career adaptability of nursing students, it suggests that it is necessary not only to recognize strengths with positive thinking about individuals, but also to improve attitudes to form desirable outcome expectations at the same time.

An increasing demand for esthetic restorations has led to the development of new ceramic systems. In-Ceram, a glass-infiltrated alumina ceramic has three to few times greater flexural strength than other ceramic glass material. Because of its high strength, In-Ceram has been suggested as inlay, crown, laminate veneer and core material for resin bonded fixed partial dentures. This clinical application requires a stable resin bond to In-Ceram core. The purpose of this study was to evaluate the shear bond strength between In-Ceram core and resin cements according to various surface treatments and storage conditions. The surface of each In-Ceram core sample was subjected to one of the following treatments and then bonded to Panavia 21 or Variolink II resin cement. ; (1) sandblasting with $110{\mu}m$ aluminum oxide powder, (2) sandblasting and silanization, (3) sandblasting and Siloc treatment, (4) sandblasting and Targis link application. Each of eight bonding groups was tested in shear bond strengths after the following storage times and thermocycling. ; A) 24 hours storage in distilled water at $37^{\circ}C$, B) 5 weeks storage in distilled water at $37^{\circ}C$ C) 5 weeks storage in distilled water at $37^{\circ}C$ and thermocycled 2,000 thormocycling for every 10 days(totally 10,000 thermocycting) in $5^{\circ}C-55^{\circ}C$ bath. The bond failure modes were observed with scanning electron microscope(SEM). The results were as fellows : 1 The shear bond strengths of sandblasting group were significantly lesser than the other groups after 24 hours water storage. No significant difference of bonding strengths was found between storage time conditions(24 hours and 5 weeks). The shear bond strengths showed a tendency to decrease in Variolink II bonding groups and to increase in Panavia 21 bonding groups. 3. After thermocycling, the shear bond strengths of all groups were significantly decreased(p<0.01) and Targis link group exhibited significantly greater strengths than the other groups(p<0.05). 4. Panavia 21 bonding groups exhibited significantly greater bonding strengths in sandblasting group(p<0.01) and silane group(p<0.05) than Variolink II bonding groups. 5. In observation of bond failure modes, Targis link group showed cohesive failure in resin part and silane group and Siloc group showed complex failure and sandblasting group showed adhesive failure between In-Ceram and resin.
