The purpose of this study is to investigate the effect of color, shirt tone, tie tone, perceiver's gender on impression formation by applying tone on tone coloration of shirt and necktie: coloration of two colors. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 32 upper body photographs which were color outputs by CAD system(4D-box program). We unified those colors of shirts and neckties same, then made shirt and necktie tone differently. 27 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate the impression. The subjects of this research were 192 male and 192 female college students in Gyeongnam province including Jinju City. The data was analyzed by using SPSS program. Analysis methods were four-way ANOVA. The items of the adjectives were classified into 5 impression dimension. - potency, activity, attractiveness, visibility and tenderness. Color, shirt tone, tie tone, and perceiver gender influenced on 5 impression formation by interaction as well as independently. Blue tie with vivid, light or dull tone had an effect on the formation of potency impression, vivid or light tone of shirt affected activity regardless of color or tie tone. As shirt and tie had different tone, effect on the formation of attractiveness impression, light tone had a negative effect on visibility but positive effect on tenderness. red color were more effective than blue expressed on visibility and tenderness in shirt or tie.

Bone marrow-derived mesenchymal stem cells (BM-MSCs) can differentiate into endothelial cells in an inflammatory microenvironment. However, the regulatory mechanisms underlying this process are not entirely understood. Here, we found that TIE2 in BM-MSCs was upregulated at the transcriptional level after stimulation with tumor necrosis factor-alpha (TNFα), a major pro-inflammatory cytokine. Additionally, the STAT-binding sequence within the proximal region of TIE2 was necessary for TNFα-induced TIE2 promoter activation. TIE2 and STAT3 knockdown reduced TNFα-induced endothelial tube formation in BM-MSCs. Among the major TNFα-activated MAP kinases (ERK1/2, JNK1/2, and p38 MAPK) in BM-MSCs, only inhibition of the p38 kinase abrogated TNFα-induced TIE2 upregulation by inhibiting the JAK-STAT signaling pathway. These findings suggest that p38 MAP contributes to the endothelial differentiation of BM-MSCs by activating the JAK-STAT-TIE2 signaling axis in the inflammatory microenvironment.

The purpose of this study is to investigate the effect of shirt color, tie color, tone, perceiver' gender on impression formation by applying tone-in-tone coloration of shirt and necktie: coloration of two colors. This experiment was designed to utilize the $2{\times}6{\times}4{\times}2$ factorial designs. and they are shirt color(red, blue), tie color(red, yellow red, yellow, green, blue, purple), tone(vivid, light, dull, dark), and perceiver' gender(a male, a female). The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 48 upper body photographs which were color outputs by CAD system(4D-box program). The subjects of this research were 288 male and 288 female college students. There were established impression dimension from factor analysis 27 bi-polar adjectives and investigated the effect of interaction between each variable affected impression formations. The items of the adjectives are classified into 4 Impression dimensions: activity, potency, attractiveness, and tenderness. Shirt color, tie color, tone, and perceiver' gender influenced on impression formation. Specially, tie color and tone influenced on the 4 impression dimension greatly by interaction as well as independently. As a result tie is very important clue of impression formation in tone-in-tone coloration of shirt and necktie. Even though tie occupies only a small area in men's clothes it has great effect since it is close to the face.

We study the antecedents to tie formation on an (Facebook-like) enterprise social media platform implemented to support cross-boundary connections. Research has produced mixed findings regarding the role of social media in cultivating bridging vs. closed networks. We examine the tie formation patterns of 1,386 enterprise social media users over a two-year period. Specifically, we observe who became (or chose not s become) "friends" with whom at the dyadic level and relate the decisions to various mechanisms that affect one's network to expand, constrain, or bridge. Using logistic and OLS regressions, we find that users tend to form ties via reciprocity and transitivity (with friends of friends), both of which help expand one's network. We also find strong networking tendency toward functional and hierarchical homophily (same business unit and same rank, respectively), which is likely to constrain one's network (closed network structure). We find that one's participation in various online interest groups is likely to open one's network (bridging network structure) while no evidence found for preferential attachment. Overall, we find that enterprise social media offers features, some of which are likely to foster bridging while others foster closed networks via different mechanisms.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

Masonry constructions exhibit uncertain behaviors under dynamic effects such as seismic action. Complex issues arise in the idealization of structural systems of buildings having different material types and mechanical properties. In this study, the structural behavior of a vaulted masonry building constructed using full clay brick and lime-based mortar and sitting on consecutive arches was investigated by experimental and numerical approaches. The dimensions of the structure built in the laboratory were 391 × 196 cm, and its height was 234 cm. An incremental repetitive loading was applied to the prototype construction model. Along the gradually increasing loading pattern, the load-displacement curves of the masonry structure were obtained with the assistance of eight linear displacement transducers. In addition, crack formation areas, and relevant causes of its formation were determined. The experimental model was idealized using the finite element method, and numerical analyses were performed for the area considered as linear being under similar loading effect. From the linear analyses, the displacement values and stress distribution of the numerical model were obtained. In addition, the effects of tie members, frequently being used in the supports of curved load-bearing elements, on the structural behavior were examined. Consequently, the experimental and numerical analysis results were comparatively evaluated.

Background A tie-over dressing is the accepted method to secure skin grafts in order to prevent haematoma or seroma formation. We describe the novel application of a barbed suture tie-over for skin graft dressing. The barbs act as anchors in the skin so constant tensioning of the suture is not required. Methods From January 2014 to August 2014 we used the technique in 30 patients with skin defects requiring split-thickness or full-thickness grafts. Patient demographics, clinicopathological details and graft outcome were collected prospectively. Results The majority of cases were carried out for split-thickness skin grafts (n=19) used on the lower limb (n=20). The results of this novel technique were excellent with complete (100%) graft take in all patients. Conclusions Our results demonstrate the clinical application of a barbed device for securing skin grafts with excellent results. We find the technique quick to perform and the barbed device easy to handle, which can be applied without the need for an assistant.

In 1953, theoretical physicist George Gamow attempted to explain the process of protein synthesis by hypothesizing that the base sequence of DNA encodes a protein's amino acid sequence and, in response, proposed the nucleic acid-protein information transfer model, which he dubbed the "diamond code." After expressing interest in discussing the daring hypothesis, contemporary biologists, including James Watson, Francis Crick, Sydney Brenner, and Gunther Stent, were soon invited to join the RNA Tie Club, an informal research group that would also count biologists and various researchers in physics, mathematics, and computer engineering among its members. In examining the club's formation, growth, and decline in multidisciplinary research on deciphering the genetic code in the 1950s, this paper first investigates whether Gamow's idiosyncratic approach could be adopted as a collaborative research forum among contemporary biologists. Second, it explores how the RNA Tie Club's research agenda could have been expanded to other relevant research topics needing multidisciplinary approach? Third, it asks why and how the RNA Tie Club dissolved in the late 1950s. In answering those questions, this paper shows that analyses on the intersymbol correlation of the overlapping code functioned to integrate diverse approaches, including sequence decoding and statistical analysis, in research on the genetic code. As those analyses reveal, the peculiar approaches of the RNA Tie Club could be regarded as a useful method for biological research. The paper also concludes that the RNA Tie Club dissolved in the late 1950s due to the disappearance of the collaborative research agenda when the overlapping code hypothesis was abandoned.
