Recently, research on the self-healing of concrete using bacteria has been actively conducted. The self-healing method using bacteria has a low self-healing rate and the surrounding environment of the fracture site is very important. A previous study to solve this problem involves the manufacture of capsules using 3D printing. Fracture position control was an important topic in 3D printing-based capsules. In this study, to compensate for the shortcomings of existing studies, a capsule capable of selective destruction location control was produced using PDMS-based molds that are not restricted by the environment. Resin capsules were prepared for each part using several molds and a bonding surface was arranged. In order to verify this on the bonding surface, fracture strength and wave unit values were analyzed through a three-way compression experiment. It can be seen that as the curing time increases, the deviation between samples decreases. In addition, through experiments, it was confirmed that the junction surface and wave unit values coincide in all three directions. It can be used for self-healing research using various solutions.

Molecular self-assembly has several advantages over other nanofabrication methods. Molecular building blocks ensure ultrafine pattern precision, parallel structure formation allows for mass production and a variety of three-dimensional structures are available for fabricating complex structures. Nevertheless, the molecular interaction for self-assembly generally relies on weak forces such as van der Waals force, hydrogen bonding, or hydrophobic interaction. Due to the weak interaction, the structure formation is usually slow and the degree of ordering is low in a self-assembled structure. To promote self-assembly, directed assembly methods employing prepatterned substrates or external fields have been developed and gathered a great deal of technological attention as a next generation nanofabrication process. In this presentation a variety of directed assembly methods for soft nanomaterials including block copolymers, peptides and carbon nanomaterials will be introduced. Block copolymers are representative self-assembling materials extensively utilized in nanofabrication. In contrast to colloid assembly or anodized metal oxides, various shapes of nanostructures, including lines or interconnected networks, can be generated with a precise tunability over their shape and size. Applying prepatterned substrates$^{1,2}$ or introducing thickness modulation$^3$ to block copolymer thin films allowed for the control over the orientational and positional orderings of self-assembled structures. The nanofabrication processes for metals, semiconductors$^4$, carbon nanotubes$^{5,6}$, and graphene$^{6,7}$ templating block copolymer self-assembly will be presented.

Purpose: The purpose of this study was to examine the effects of diabetic foot care education for the older adults with low health literacy. Methods: A quasi-experimental design with a non-equivalent control group pretest-posttest was used. The participants who were diagnosed with diabetes, were adults over 65 years old at the welfare center of Y and B city. They were divided into the experimental group (n=32) and the control group (n=31). Inclusion criteria were a score of 5 or under on the Short form of Korean Functional Health Literacy Test and 24 or more on the Korean version of Mini-Mental State Examination. Foot care education was conducted in a small group for 40 minutes, once a week, for three weeks. The education materials are composed of an easy term, picture and photographs to understand easily. Results: The scores of diabetic foot care knowledge (t=4.57, p<.001), foot care self-efficacy (t=6.07, p<.001), and foot self-care behavior (t=4.18, p<.001) were significantly increased in the experimental group compared to the control group. Foot health status was not significantly improved. Conclusion: The findings indicate that this education program can be used as a nursing intervention improving foot care knowledge, foot care self-efficacy, and foot self-care behavior in order to prevent the diabetic foot problems of elderly diabetic persons with low health literacy.

The purpose of this study was to investigate the effect of metacognitive strategy on conceptual acquisition ofvseasonal change and self-efficacy when it was applied to 6th grade elementary students. This study consists of 2 classes, 76 students in the 6th grade of elementary school, which were divided into the experimental group (38) and the control group (38). First, a pre-test was administrated to check students' levels of metacognitive self-regulation and self-efficacy prior to getting planned lessons and then an instruction program was developed based upon the metacognitive instruction model and students' conception. The control group was exposed to traditional methods mainly using the textbook and teacher's guide book. The experimental group employed a metacognitive learning strategy program and activities with metacognitive questionnaires. After the planned lessons, the students were tested with post-tests about the conception of seasonal change and self-efficacy. One month later the students were tested again with another test to determine the continuation effect. The results were as follows: First, the group that used metacognitive conceptual change instruction did better in forming and continuing to maintain the scientific seasonal change conceptions compared to the control group. Second, the high and intermediate group taught by metacognitive conceptual change instruction was higher in the level of self-regulation than the control group. However, it was not verified in the low group. Third, the group which used metacognitive conceptual change instruction showed a higher level of self-efficacy than the control group did.

Behavior modification is an approach to decrease degree of obesity through changing maladaptive eating habit and life style. It produces small amount of weight loss but it has few side effects and low dropout rate. It also has great effectiveness on maintenance of decreased weight. This study was performed to investigate effects of behavior modification on physical variables, fat and thin habit, and self-esteem in obese elementary school children. Sixty two students of 4th, 5th, and 6th grade were selected from two elementary schools located in the suburbs of Seoul. Thirty four children in one school were assigned to experimental group and twenty eight children in another school were assigned to control group. All subjects were healthy and were not on any type of obesity control. Behavior modification, in this study, was consisted of introduction, self-monitoring and stimuli control, education about diet and physical activities, individual counseling and reinforcement, requesting personal assistance, cognitive restructuring, and closing and long-term planning. Experimental group was received 60～70 minutes of behavior modification once a week for 8 weeks from October 16 to December 22, 2000. Control group was not received any intervention. Data were collected before and after intervention by measuring physical variables, fat and thin habit, and self-esteem. Physical variables consisted of obesity index, skinfold thickness, body fat(percentage of body fat, fat mass, fat free mass), serum lipids(total cholesterol, HDL-C, LDL-C, triglyceride) and serum leptin. The results were as follows ; 1. physical variables 1) Obesity index of the experimental group was significantly decreased after behavior modification. But there was no significant difference between two groups. 2) The increase of skinfold thickness was significantly low in the experimental group compared to the control group. 3) Percentage of body fat and fat mass were significantly decreased in the experimental group. Fat free mass was significantly increased in the experimental group. 4) Total cholesterol, HDL-C, triglyceride and serum leptin between the experimental group and control group showed no significant difference. LDL-C was significantly decreased in the control group. 2. Thin habit score was significantly increased in the experimental group. In subcategories of habit, thin scores of life style, attitude, social relationship, nutrition were signifi- cantly increased in the experimental group. 3. Self-esteem score was significantly increased in the experimental group. These results indicate that behavior modification is effective in decreasing percentage of body fat and fat mass, in less increasing skinfold thickness and in increasing fat free mass, thin habit, and self-esteem. In conclusion, behavior modification can be used as safe and effective strategy for managing obesity in elementary school children.

Purpose: The purpose of the study was to identify the mediating effects of social support and self-efficacy between academic stress and college adjustment in physical therapy students. Design: Survey. Methods: 75 subjects were surveyed about the level of academic, Academic Stress, College Adjustment, Social Support, Self-Efficacy, and self-control. To confirm the cognitive function on brain activity were evaluated. Results: First, College students have higher academic stress and lower college adjustment. Higher social support and self-efficacy have lower academic stress and better college adjustment. Second, students with high academic stress need constant attention to increase their social support and programs to reduce academic stress. Third, students with high academic stress, low social support, and low self-efficacy can increase their cognitive strength through the brain wave thereby reducing the academic stress they are currently feeling. Conclusion: In order to improve the College Adjustment, it is considered that it is important to increase the cognitive function through brain train along with the development of a student management program that can reduce academic stress and increase social support and self-efficacy.

Purpose - This study examines the strength of sadness and the belief it will last, as regards the effects of the degree of self-extension to the sad-evoking event on choice behavior related to self-control dilemmas. Research Design, Data, and Methodology - In an experiment involving high and low self-extension groups, 261 undergraduates answered self-administered questionnaires. The hypotheses were tested using AMOS 19.0 and path analysis. Results - The positive relationship between the degree of self-extension to the sad-evoking event and hedonic vs. utilitarian food choices was mediated by the belief that the sadness will last. There is a significant indirect path from the degree of self-extension (to the sad-evoking event) to the strength of the sadness, and to the belief that it will last with respect to hedonic vs. utilitarian food choices. Conclusions - These results show that beliefs about sad emotion transience depend on both the degree of self-extension to the sad-evoking event and the strength of sadness, and that the belief that sad emotions are transient makes sad people susceptible to temptation when facing self-control related dilemmas.
