The purpose of this study is to identify the effect not of therapeutic behavior but of the balance evaluation process itself on the balance ability of the elderly. For this, 36 elderly people over 65 age belonging to two elderly welfare centers in Jeonju city were divided into 3 groups of 12 each. All participants were divided into three groups, one was the daily evaluation, another was weekly, and the other group was twice at the beginning and the end of the study. And this study conducted for 4 weeks totally. The balance scale that we used one was Berg Balance Scale and for comparison within groups and between groups, Paired t-test and one-way ANOVA methods were used. The post-hoc test was used 'Scheffe test', and the significance level was α = .05. The results showed that the balance ability was significantly improved after 4 weeks in all three groups. Among all groups, the highest improvement was observed in the daily evaluation group and the lowest improvement was observed in the general evaluation group. In the comparison between the groups, it was confirmed between the daily evaluation group and the weekly evaluation group, between the daily evaluation group and the general evaluation group. These results show that the evaluation process using the balance function scale, rather than the therapeutic behavior, can affect the balance ability of the elderly. I would like to be able to utilize this basic research data that just evaluation of balance function using balance scale in the social facilities and institutions for the elderly can positively influence the improvement of the balance function and strengthen the postural controling ability necessary for the independent daily life practice.

As becoming an aging society, there is a rising interest on dementia. But Dementia prevention program, executed at the national level, is in insufficient state. In this study, to design and diffuse Dementia prevention program, this study conduct Cognition improvement program and evaluate cognitive function in aspects of Discrimination, Organization, Thinking, Memorizing, and Concentration capacity. So that this study try to investigate how this Cognition improvement program will affect in detail to cognitive function in senior people. This study designed Silver Cognition program for 5 aspects of cognitive function; Discrimination, Organization, Thinking, and Concentration capacity. And this studyrecruited experimental group with control group, and conducted the program to them for 3 months. At the start and the end of the program, this study evaluated their MMSE-DS score, Geriatric depression scale, Quality of life score, and cognitive function test score by survey. Finally, this study compared and analyzed these first and second score to find the effects of this program to cognitive function. As the results compared between first and second score of MMSE-DS test, Geriatric depression scale, Quality of life scale, and cognitive function test, Silver Cognition program has a significant effects to improve cognitive function, MMSE-DS score and Geriatric depression scale. As the results of the test on cognitive function in 5 aspects, cognitive function is more improved in the order of Memorizing, Thinking, Concentration, Discrimination, and Organization capacity. After the Silver Cognition program, Memorizing and Thinking capacity have most improvement. But aging of brain function is faster in these two capacity, so if more concentrated education is conducted for these two capacity, then it will bring better effects for prevention of dementia.

The purpose of this study was to evaluate the relationship between periodontal disease and halitosis, and to develop a detail clinical protocol for assessing halitosis in animals. We measured the periodontal disease parameters, the degree of halitosis using organoleptic scale method and the concentration of volatile sulfur compounds(VSC) using portable sulfide monitor($Halimeter^{TM}$). In this study, VSC levels by $Halimeter^{TM}$ were found to be significantly associated with periodontal disease parameters(plaque index, calculus index)(P<0.05). We also found that conscious sedation did not affect the measurement of VSC levels.

Polymer brush is a soft material unit tethered covalently on the surface of scaffolds. It can induce functional and structural modification of a substrate's properties. Such surface coating approach has attracted special attentions in the fields of stem cell biology, tissue engineering, and regenerative medicine due to facile fabrication, usability of various polymers, extracellular matrix (ECM)-like structural features, and in vivo stability. Here, we summarized polymer brush-based grafting approaches comparing self-assembled monolayer (SAM)-based coating method, in addition to physico-chemical characterization techniques for surfaces such as wettability, stiffness/elasticity, roughness, and chemical composition that can affect cell adhesion, differentiation, and proliferation. We also reviewed recent advancements in cell biological applications of polymer brushes by focusing on stem cell differentiation and 3D supports/implants for tissue formation. Understanding cell behaviors on polymer brushes in the scale of nanometer length can contribute to systematic understandings of cellular responses at the interface of polymers and scaffolds and their simultaneous effects on cell behaviors for promising platform designs.

In order to identify effective approaches for creating more viral Facebook posts, this research conducted an empirical content analysis of leading Korean brands' Facebook fan-pages (Samsung Mobile, SK Telecom, Kia Motors, and POSCO). Their distinctive visual storytelling and communication patterns were investigated as effective user engagement triggers. Through analysis of the research results, it was statistically proved that the different industrial attributes of the four brands, which are primarily characterized by their product (or service) types, affect their Facebook posting patterns by showing different engaging rates (measured by like, comment, and share metrics). In addition, the user engagement rates of the posts were influenced by their visual storytelling factors (i.e. ad objective, value scale, and visual media types). In line with these statistical findings, the distinctive visual storytelling strategies of the four brands were identified. Moreover, competitive and uncompetitive visual storytelling tactics were suggested according to the ad objectives and visual media types on Facebook.

The structural collapse of masonry structure under dynamic loading displays many possible failure mechanisms often related to interaction between structural components. Roof collapse is one of the major damage mechanisms observed in masonry structures during an earthquake. Better connection between the roof diaphragm and walls may be preventing roof collapse, but it can affect other failure mechanisms. In spite of this fact, less attention has been paid to the influence of the roof diaphragm effect on masonry structures and little research has been implemented in this field. In the present study, the roof diaphragm effect on the unreinforced masonry structure under dynamic loading has been experimentally investigated. Three one-quarter scale one-story adobe masonry house models with different roof conditions have been tested by subjecting them to sinusoid loading on a shaking table simulator. Phenomena such as failure pattern, dynamic performance of masonry structure were examined.

High frequency induction welding is widely employed for longitudinal seam welding of small scale tubes and pipes because of its relatively high processing speed and efficiency. This research is aimed at understanding the variables that affect the quality of the high frequency induction welding. The welding variables include the welding frequency, weld speed, V-angle and tube thickness. Temperature distribution of the tube is calculated through three dimensional coupled electromagnetic and thermal FE analysis. The skin and proximity effects are considered in the electromagnetic analysis. The influence of the impeder is also analyzed. The effects of the operating welding variables on the temperature distribution are investigated quantitatively by exhibiting the heat affected zone (HAZ). The results explain the mechanism of significant enhancement of welding efficiency when the impeder is used. The proper welding conditions without the overheated edge are obtained through FE analysis.

The purpose of this study was to examine the pathway in which children characteristics, maternal warmth, and children's academic competence affect the quality of children's peer relationships. A total of 291 children (Mage=11.4) responded to questionnaires DOTS-R (Windle & Lerner, 1986), MBRI (Schaefer, 1959), Academic Self-Efficacy Scale (Kim & Park, 2002), and FQQ (Parker & Asher, 1993). Data were analyzed via Structural Equation Modeling. Our results indicated that children's academic competence fully mediated the association between temperament and the quality of peer relationships, whereas it was a partial mediator in relations between maternal warmth and the quality of peer relationships. A difference in terms of gender was also present in this path model. In conclusion, children's temperaments and maternal warmth affected the quality of peer relationships both directly and indirectly through children's academic competence.

We report preliminary results from a radio study of central galaxies in cool and non-cool core clusters. A cooling flow is expected to rapidly form in the center of galaxy clusters unless additional heating mechanisms such as merging with sub clusters are at work. It has been suggested that cool flows can feed the AGN in the central galaxies, increasing their power. On the other hand, the AGN feedback can also affect the surrounding medium, heating back up the gas in the cluster core region. In this study, we investigate the co-evolution of cool flows and the AGN of galaxies located in the cluster center. For this study, we have selected 13 radio bright central galaxies from clusters with a range of cooling time scale. In this work, we present results of our recent observations using the Korean VLBI Network. We discuss the properties of the sample in radio and other wavelengths.
