Abstract: Training Worthy Of Children, Knowledge, Motivation Of Village Formation Worthy Of Children. The objective of the research is to analyze the influence of village-worthy training on the knowledge and motivation of the community about the establishment of a village worthy of children in Ngargurejo, Ngemplak, Boyolali. It is a quasi-experimental study with an experimental pre-post design. Research respondents are all stakeholder Ngargorejo, Ngemplak, Boyolali as many as 40 people. Sampling techniques use proportional sampling by selecting representatives from all stakeholders with the aim that the chosen research subject can truly represent the roles and responsibilities of each stakeholder. Data obtained through interviews and filling questionnaires. The results of this study (1) The Effectiveness of ChildFriendly Village Training on Knowledge shows the average value of respondents' knowledge about DLA is 82.06, median value of middle or 65, the most common mode or value 0, standard deviation of 82.7 with The highest or maximum value of 330 and the lowest or minimum value is 0. Based on table 5.5. Seen the average value of knowledge of respondents after training DLA is 205.3, median 201,5, mode 210, standard deviation 57,58, highest value 300 and lowest 25. Based on table 5.7. Seen that the average value of knowledge of respondents increased from 82.62 ± 82.72 to 205.25 ± 57.57. Since the value of p (Sig 2-tailed), 0.001 is smaller than 0.05 it can be concluded that DLA training significantly affects the improvement of respondent knowledge about DLA. (2). Based on statistical tests with t-test, although there is an increase in mean value of motivation to implement the DLA program from 62,83 ± 10,20 increase to 63,65 ± 4,78, but because p-value (Sig 2-tailed) = 0,629 more Large from 0.05 then it can be concluded DLA training does not affect the increase in motivation to implement DLA program. DLA training had a significant effect to improve knowledge about DLA with paired sample-test 0,001, but Child's Decent Village Training did not influence society's motivation with result p = 0,629.

This study tested whether three different cement layer thicknesses (60, 120 and 180 μm) would provide the same bonding capacity between adhesively luted lithium disilicate and human dentin. Ceramic blocks were cut to 20 blocks with a low-speed diamond saw under cooling water and were then cemented to human flat dentin with an adhesive protocol. The assembly was sectioned into 1 mm2 cross-section beams composed of ceramic/cement/dentin. Cement layer thickness was measured, and three groups were formed. Half of the samples were immediately tested to evaluate the short-term bond strength and the other half were submitted to an aging simulation. The microtensile test was performed in a universal testing machine, and the bond strength (MPa) was calculated. The fractured specimens were examined under stereomicroscopy. Applying the finite element method, the residual stress of polymerization shrinkage according to cement layer thickness was also calculated using first principal stress as analysis criteria. Kruskal–Wallis tests showed that the ‘‘cement layer thickness’’ factor significantly influenced the bond strength results for the aged samples (p = 0.028); however, no statistically significant difference was found between the immediately tested groups (p = 0.569). The higher the cement layer thickness, the higher the residual stress generated at the adhesive interface due to cement polymerization shrinkage. In conclusion, the cement layer thickness does not affect the immediate bond strength in lithium disilicate restorations; however, thinner cement layers are most stable in the short term, showing constant bond strength and lower residual stress.
