In traditional social network analysis, the betweenness centrality measure has been heavily used to identify the relative importance of nodes in terms of message delivery. Since the time complexity to calculate the betweenness centrality is very high, however, it is difficult to get it of each node in large-scale social network where there are so many nodes and edges. In this paper, we define a new type of network, called the expanded ego network, which is built only with each node's local information, i.e., neighbor information of the node's neighbor nodes, and also define a new measure, called the expended ego betweenness centrality. Through the intensive experiment with Barab$\acute{a}$si-Albert network model to generate the scale-free networks which most social networks have as their embedded feature, we also show that the nodes' importance rank based on the expanded ego betweenness centrality has high similarity with that based on the traditional betweenness centrality.

This research examines embroidery panels of Hwarot belonging to the Victoria and Albert Museum (the V&A). There are a total of seven objects and are all disassembled into clothe pieces. They were classified into two groups according to their acquisition year. One group, four objects, was acquired by the Museum in 1920. Considering their materials, embroidery threads, techniques and formative characteristics of patterns, it can be assumed that the objects formed an original dress, Hwarot. Although they look very similar to the embroidery patterns of Hwarot belonging to National Folklore Museum of Korea, they are more finely embroidered with very thin embroidery thread that uses the Jarisu technique. There are some differences in used embroidery threads and embroidery skills between Hwarot artifacts of the National Museum of Korea and the V&A. The embroidery of the National Museum of Korea used thicker threads and longer (approximately 0.7cm) Jarisu stitch techniques. With these details, they would have been made in different time periods. Comparison of the V&A and Changdeok Palace' Hwarot objects show that their patterns' motifs are almost similar but the pattern units, expressions and embroidery techniques are different. Regarding the colors of their patterns, it is noticeable that the peonies are generally expressed in reddish and the lotus patterns are expressed in either bluish or purplish color. It seems that they are contrasted with red-colored flowers and show harmony between yin and yang symbolically. Three artifacts of another group were acquired in 1925. Two of them show patterns almost the same as those of the sleeves of Hwarot (no.33156, no.33158) in Chicago Field Museum collection. The pattern of the remaining object is very similar to Hansam of Hwarot (no.33158).

Background Digital amputation is a common upper extremity injury and can cause significant impairment in hand function, as well as psychosocial stigma. Currently, the gold standard for the reconstruction of such injuries involves autologous reconstruction. However, when this or other autologous options are not available, prosthetic reconstruction can provide a functionally and aesthetically viable alternative. This study describes a novel technique, known as a tripod titanium mini-plate, for osseointegrated digit prostheses, and reviews the outcomes in a set of consecutive patients. Methods A retrospective review of patients who underwent 2-stage prosthetic reconstruction of digit amputations was performed. Demographic information, occupation, mechanism of injury, number of amputated fingers, and level of amputation were reviewed. Functional and aesthetic outcomes were assessed using the quick disabilities of the arm, shoulder, and hand (Q-DASH) scale and a visual analog scale (VAS) score, respectively. In addition, complications during the postoperative period were recorded. Results Seven patients were included in this study. Their average age was 29 years. Five patients had single-digit amputations and 2 patients had multiple-digit amputations. Functional and aesthetic outcomes were assessed using the Q-DASH score (average, 10.4) and VAS score (average, 9.1), respectively. One episode of mild cellulitis was seen at 24 months of follow-up. However, it was treated successfully with oral antibiotics. No other complications were reported. Conclusions When autologous reconstruction is not suitable for digit reconstruction, prosthetic osseointegrated reconstruction can provide good aesthetic and functional results. However, larger series with longer-term follow-up are required in order to rule out the possibility of other complications.

Systematic analysis of caffeine from the commercial samples of Indian tea leaves was performed by a routine method and the content of caffeine was found to be 19.0-37.4 mg/100 g leaves. The caffeine contents from coffee seeds and chicory from Indian origin were analyzed and found to be 0.6540-1.4920 g/100 g seeds. Caffeine contents of roasted Indian chicory roots were lower than either those of Indian tea leaves or Indian coffee seeds. The multidrug resistance (MDR) reversing effects were tested on a mouse leukemia cell line of L-5178 cells by methanol extracts [M1-M15] of Indian tea leaves and coffee seeds, comparing to a control of $({\pm})-verapamil$. The effects were measured by fluorescence ratio between treated and untreated group cells. Among fifteen methanol extracts, a Gemini tea [M6] (fluorescence activity ratio 5.26) had the most potent effect for L-5178 cells. The extract M6 was 0.63-fold of $({\pm})-verapamil$. We suggest that one of mechanisms of reversal by M6 might have strong affinity to dopamine $D_1$ and D_2$ receptors. Further studies with many more tumor and normal cell lines are necessary to confirm the MDR reversal specificity of coffee methanol extracts.

The metabolic syndrome, by definition, is not a disease but is a clustering of individual metabolic risk factors including abdominal obesity, hyperglycemia, hypertriglyceridemia, hypertension, and low high-density lipoprotein cholesterol levels. These risk factors could dramatically increase the prevalence of type 2 diabetes and cardiovascular disease. The reported prevalence of the metabolic syndrome varies, greatly depending on the definition used, gender, age, socioeconomic status, and the ethnic background of study cohorts. Clinical and epidemiological studies have clearly demonstrated that the metabolic syndrome starts with central obesity. Because the prevalence of obesity has doubly increased worldwide over the past 30 years, the prevalence of the metabolic syndrome has markedly boosted in parallel. Therefore, obesity has been recognized as the leading cause for the metabolic syndrome since it is strongly associated with all metabolic risk factors. High prevalence of the metabolic syndrome is not unique to the USA and Europe and it is also increasing in most Asian countries. Insulin resistance has elucidated most, if not all, of the pathophysiology of the metabolic syndrome because it contributes to hyperglycemia. Furthermore, a major contributor to the development of insulin resistance is an overabundance of circulating fatty acids. Plasma fatty acids are derived mainly from the triglycerides stored in adipose tissues, which are released through the action of the cyclic AMP-dependent enzyme, hormone sensitive lipase. This review summarizes the latest concepts in the definition, pathogenesis, pathophysiology, and diagnosis of the metabolic syndrome, as well as its preventive measures and therapeutic strategies in children and adolescents.

Objective: This study reports the effectiveness of the Korean medicine treatment of patients with intracerebral and intraventricular hemorrhages suffering unilateral neglect symptoms. Case presentation: The patient was treated using Korean medicine, including acupuncture, herbal medicine, moxibustion, and a limb activation exercise. We measured Unilateral Neglect Symptom progress with a numeric rating scale, Albert's test, Line bisection test, Clock drawing test, and Catherine Bergego Scale. After eight days of combined Korean medicine and rehabilitation exercise, the Unilateral Neglect Symptom intensity reduced from NRS 8 to 6. In addition, Albert's test score decreased from 2.5% to 0%. The Line bisection test score decreased from 19 mm to 12 mm, and the Clock drawing test score improved from 8 to 10. Last, the Catherine Bergego Scale decreased from 12 to 9. No adverse events were observed during treatment. Conclusion: This study suggested that a complex treatment including Jaeumkunbi-tang, acupuncture, moxibustion, and limb activation exercise can be effective for an intracerebral hemorrhage with intraventricular hemorrhage patient suffering from Unilateral Neglect Symptoms. Consequently, more research is needed in the future.

In the moral culture of the West, love and justice are two commands with roots in ancient times. One is the heritage of Hebraism, and the other belongs to the tradition of Hebraism and Hellenism. The two concepts are the most important virtues required for preserving stability in society. These two commands are compatible, in an exclusive relationship to each other. To ultimately seek their reconciliation, the precise concept analysis and understanding of each of them should be premised on, due to the multi-layered meaning of implications of the two concepts. To this end, we first have started with a lexical meaning and have done a conceptual analysis of what these two concepts are expressing. We have looked at Paul $Ric{\oe}ur$ in his interpretation of the discourse of love and justice. Finally, we looked at how these two concepts are narrated in literature. Through the literary works of Stendal, Albert Camus, and Dostoevsky, we have seen examples of literary configurations that have been embodied in life. In this way, through conceptual analysis, discourse analysis, and narrative analysis of the two concepts, the following conclusions were drawn. Love and justice were not a matter of choice. We could see coldness and unrealism of a society lacking love or with a problem of unclean love, through Stendhal's and Albert Camus' novels and their actual debate. In addition, in unclean paternalism, risk of the power of love blocking certain a certain touch of justice was also confirmed. So, it was necessary for a healthy future society to explore the possibility of the coexistence of love and justice. We confirmed the possibility of compatibility in a 'considerate balance' wherein the 'moral judgment in situation' is required, as Paul $Ric{\oe}ur$ expressed. This ideal situation may be realized when forms of love involving solidarity, mutual care, and compassion with pain like Dostoevsky are combined with the principle of distributional justice. When Albert Camus pursued justice and eventually faced reality and mentioned the need for mercy, he could have made a moral judgment based on this situation. In the end, love protects justice, and justice contributes to the realization of love. Justice reduces super-ethical love to moral categories, and love plays a role in enabling justice to exert its full force.

Concrete-filled tubes (CFT), formed by an outer steel tube filled with plain or reinforced concrete inside, have been increasingly used these recent decades as columns or beam-columns, especially for tall buildings in seismic areas due to their excellent structural response. This improved behavior is derived from the effect of confinement provided by the tube, since the compressive strength of concrete increases when being subjected to hydrostatic pressure. In circular CFTs under compression, the whole tube is uniformly tensioned due to the radial expansion of concrete. Contrarily, in rectangular and square-shaped CFTs, the lateral flanges become subjected to in-plane bending derived from this volumetric expansion, and this fact implies a reduction of the confinement effect of the core. This study presents a numerical analysis of different configurations of CFT stub columns with inner stiffening plates, limited to the study of the influence of these plates on the compressive behavior without eccentricity. The final purpose is to evaluate the efficiency in terms of strength and ductility of introducing stiffeners into circular and square CFT sections under large deformation axial loading.
