In this study, electro-deposition method was applied to heal cracks in various blended concrete. The performance of the method was indirectly monitored by measuring impressed voltage, electrolyte, galvanic current monitoring, linear polarization resistance, and directly by image analysis of the cracks. The indirect and direct monitoring values are compared to develop guidelines for relating the indirect measures to actual crack healing. As a result, It was found that impressed voltage was convergence to 2.9V after 20000 minutes. From the galvanic current test results of artificial crack healing, the corrosion resistance showed that the order of 0.4 $>$ 0.6 $>$ 0.5 water to cement ratio. Furthermore, in view of binder, the corrosion resistance order was calculated OPC $>$ 60%GGBS $>$ 10%SF $>$ 30%PFA. Finally, It was found that 76.47% of healed crack surface calculated from the artificial crack healing technique using electrochemical deposition method.

In this study, self - healing solid capsules of crystal growth type which can be mixed directly with repair mortar were prepared, and the quality and crack healing performance of repair mortar with self - healing solid capsules were evaluated. The table flow and the air flow rate of the repair mortar material mixed with self-healing solid capsules were found to have no significant influence on table flow and air volume regardless of mixing ratio. Compressive strength tended to decrease with increasing capsule mixing ratio. As a result of evaluation of crack healing properties according to constant water head permeability test, initial water permeability decreased, and reaction products were generated over time and cracks were healed.

In this study, the self-healing performance of mortar beams containing self-healing materials was evaluated through experiments. Normal mortar beams and self-healing mortar beams were used In the experiments. The self-healing performance was evaluated by comparing the mortar compressive strength, member strength, and self-healing effects of cracks. The experimental results showed that the compressive strength of mortar containing self-healing material was smaller than that of normal mortar, but the ratio of 118 days compressive strength to 28 days compressive strength was the same. The member strength tended to increase with increasing curing period. In normal mortar specimens, the member strength did not recover even if the curing period increased, but the strength of the self-healing mortar specimens tended to recover as reaction products were produced. The crack width tended to decrease after the healing periods in both specimens, but the reaction product was observed only in the self-healing mortar specimens.

Due to the recent increase in the disabled population and welfare paradigm, the government is focusing on green welfare and environmental welfare to improve the living environment of the disabled, including the enactment of basic laws and convenience promotion laws. Accordingly, green environmental welfare for the disabled is supported in policy, but there are no evaluation indicators for the green welfare space and healing environment created. Therefore, this study divided the healing environment into physical, psychological, and social aspects, and conducted research using expert FGI to present evaluation indicators that can determine whether spatial roles and functions are appropriate. As a result of the study, the final 51 healing environment evaluation items were derived from 26 physical aspects evaluation items, 14 psychological aspects evaluation items, and 11 social aspects evaluation items. Evaluation indicators derived from this study can be used to evaluate the healing environment created in disabled residential facilities, and can be used as basic data in the planning stage of the healing environment to be created in the future.

The purpose of this study is to analyze forest healing from a Buddhist perspective and improve its effect, and the forest has a close relationship with Buddhism than any religion. the Buddha's life is connected to forest and tree, which is caused by the spiritual nature and role of forest. Healing deals with the problem of suffering of the mind, and in Buddhism, it is solved through practice. By understanding the phenomenon of delusions such as thoughts, greed, and bad feelings about sensory control, vhfptmxmhelps to escape from the desire to pursue unnecessary stimuli or external objects, Human beings can get comfort and pleasure through the five senses in the beautiful natural scenery, and find the stability of the mind. This is because when entering the forest, good environments that prevent the 6th consciousness from growing delusions way the operation of the five senses are contained in the forest, This study is a preliminary study that analyzed the effects based on the natural environmental healing factor and Buddhist theory of forests based on previous studies, As a result of examining whether Buddhism can maximize the healing effect of forest healing, it was confirmed that it can contribute to activation along with existing forest healing techniques, The verification of the effectiveness will be left as a follow-up research project through future experimental research, and this study is expected to contribute to the activation of forest healing effect.
