This article aims at developing Mind Healing Program for university students, whose anxiety and depression are getting serious. Reality therapy was experimented total 10 times(one time per week), which was the revision and supplement of Woo(1994)'s reality therapy program. It consists of introducing program and self, understanding 5 mind desires, identifying obstacles of conversation, learning efficient communication skills, controling irrational expectation of others, recognizing mind gap, problems of choice and responsibility, nurturing mind, etc. The effectiveness of this program was verified through a model whose research variants were participation motivation, participation satisfaction, and mental health. Direct effects of participation motivation, participation satisfaction, and mental health were less satisfactory than indirect effects of the time when program satisfaction is a variant. It is concluded that mental health of participants is getting better when more satisfactory program should be provided, rather than motivation of simple participation.

The concept and spatial composition of office have endlessly changed according to social trend. And according to social change, members of office, namely, concept of organization has been changed. Presently, our society finds and needs appearance of office suitable for our society. According to a concept of ecological environment and a concept laying stress on human, various trials have been performed but still, stress of salaried men is treated as social issue. By having connection between psychological healing theory of Max $L{\ddot{\bar{u}}}scher$ and spatial expression elements (content : refuge, self-esteem : prospect, confidence : flow, liberty : void) as a theory, we discussed possibility of aesthetic office landscape could be developed to a type of office which could control emotion that can be a cause of stress and we intended to examine limitation and possibility through case analysis.

This study investigated the degree of fracture healing using cathode stimulation of microcurrent, cathode and anode stimulation of High Voltage Pulsed Galvanic Current (HVPGC). Measures were performed by X-ray test and Hematoxylin-Eosin stain and Masson's trichrome stain and osteocalcin-positive immunoreactivity. In the measure of X-ray, microcurrent stimulation group revealed more rapid recovery than the groups of HVPGC's cathode and anode stimulation in bone union degrees. Microcurrent group showed significant difference statistically (p<0.05). However, the groups of HVPGC's cathode and anode stimulation didn't show significant difference statistically(p>0.05). In the histologic examination with Hematoxylin-Eosin and Masson's trichrome, microcurrent stimulation group was observed more proliferation of irregular woven bones than the groups of HVPGC's cathode and anode stimulation. Osteocalcin-positive immunoreactivity was observed more osteoblast, osteocyte, osteoclast, bone matrix than the groups of HVPGC's cathode and anode stimulation. Microcurrent stimulation can be considered an effective way during healing of fresh fracture and it can show more effective method than HVPGC's cathode and anode stimulation in the fracture healing.

Recently, due to the deterioration and various natural disasters caused by the passage of concrete pole for 20~30 years or more, damage and destruction of the poles have increased the demand for maintenance. In this paper, 10 flexural strength test specimens were fabricated by using crack self - healing concrete of Fly ash, GGBS, CA, etc. The compressive strength of the concrete with slag was found to be excellent, but the concrete with fly ash was slightly below the reference strength. In addition, the crack loadings of the specimens satisfied the criteria of KS F 4304. In the case of the load-deflection and strain relations, the behavior of the fly ash specimens was similar, but in the specimens containing the blast furnace slag, The results showed that a large amount of strain occurred.

One of the most important core technologies required for the design of the ITS (Intrusion Tolerance System) that performs continuously minimal essential services even when the network-based computer system is partially compromised because of the external or internal intrusions is the quantitative dependability analysis of the ITS. In this paper, we applied self-healing mechanism, the core technology of autonomic computing to secure the protection power of the ITS. We analyzed a state transition diagram of the ITS composed of a Primary server and a backup server utilizing two factors of self-healing mechanism (fault model and system response) and calculated the availability of ITS through simulation experiments and also performed studies on two cases of vulnerability attack.

In this study, the effect of cyclic wetting-drying on the self-healing of cementitious materials containing superabsorbent polymers (SAPs) were experimentally evaluated. In each cycle, cracked cement paste specimens containing various SAP dosages were exposed to wet conditions for 1 h, during which the capillary water absorption tests and water flow tests were conducted, and then exposed to dry conditions for 47 h. The capillary water absorption test results showed that the sorptivity values of the specimen without SAPs, SAP 0.5%, SAP 1.0%, and SAP 1.5% specimens were decreased by approximately 22.9%, 36.8%, 42.8%, and 46.3%, respectively, after 8 cycles. In addition, the water flow test results showed that the amount of water runoff through the cracks of all cracked specimens gradually decreased over wet/dry cycles, especially the reduction ratio of the amount of water runoff increased with increasing SAP dosage. Furthermore, the swelling behavior of SAPs in cracks by in gress water was con firmed via X-ray computed tomography (CT) analysis. These results indicate that the effective crack width can be reduced as SAPs absorb water and swell, while the water absorbed in SAPs can be released to crack surfaces under dry conditions, further promoting healing product formation. This study demon strates that the in corporation of SAPs can in crease the water tightness of cracks, thereby improving the self-healing efficiency of cementitious materials.
