전통적인 사회관계망 분석에 있어서 각 노드의 매개 중심도는 메시지 전달 측면에서의 각 노드들의 상대적인 중요도를 파악하는 척도로 오랫동안 사용되어 왔다. 하지만, 매개 중심도를 산출하기 위한 계산 복잡도가 높기 때문에 노드의 수와 간선의 수가 매우 많은 대규모 사회관계망에서는 각 노드의 매개 중심도를 산출하기가 어렵다. 본 논문에서는 각 노드들마다 자신의 지역정보, 즉 이웃노드들이 지닌 각각의 이웃노드 정보를 활용하여 구성가능한 확장 자아 네트워크(Expanded Ego Network)를 새롭게 정의하고 이러한 네트워크를 기반으로 확장 자아 매개 중심도(Expanded Ego Betweenness Centrality)를 정의한다. 일반적인 사회관계망의 특성인 척도 없는 네트워크(Scale-free Network)를 생성할 수 있는 Barab$\acute{a}$si-Albert 네트워크 모델을 사용한 실험을 통하여 제안한 확장 자아 매개 중심도의 각 노드별 순위는 기존의 전통적인 방식으로 산출한 매개 중심도의 각 노드별 순위와 거의 일치함을 보인다.

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.

서구의 도덕 문화에서 사랑과 정의는 고대로부터 내려온 두드러진 두 개의 명령이다. 하나는 헤브라이즘의 유산이고, 다른 하나는 헤브라이즘과 헬레니즘의 전통에 속한다. 그만큼 두 개념은 인간 공동체 사회를 안정되게 유지하는 데 필요한 가장 중요한 덕목이자 개념이다. 그런데 서로 배타적 관계로 보이는 이 두 명령은 양립 가능할까? 그들의 화해를 궁극적으로 모색하기 위해서는 그 두 개념이 함의하고 있는 의미의 다층성으로 인해 그들 각각에 대한 정확한 개념 분석과 다각도의 이해가 전제되어야 할 것이다. 이를 위해 우리는 먼저 사전적 의미에서부터 출발하여 이 두 개념이 무얼 말하는지 개념 분석 작업을 했으며, 그리고 사랑과 정의의 담론이 어떻게 해석되고 있는지 폴 리쾨르를 중심으로 살펴보았으며, 끝으로 이 두 개념이 과연 문학 작품에서는 어떻게 이야기되고 있는지, 그 문학적 형상화의 사례들(스탕달, 알베르 카뮈, 도스토예프스키의 작품들)을 통해 허구적이나마 삶 속에 구현된 모습들을 살펴보았다. 이처럼 두 개념에 대한 개념 분석, 담론 분석, 이야기 분석을 차례로 살펴본 결과, 우리는 다음과 같은 결론을 도출해낼 수 있었다. 사랑과 정의는 어느 한쪽을 선택할 문제는 아니었다. 부정한 사랑의 문제점이나 사랑이 결여된 정의사회의 냉정함과 비현실성 등은 스탕달과 알베르 카뮈의 소설적 형상화나 그들의 실제 논쟁을 통해 충분히 확인할 수 있었다. 뿐만 아니라 부정한 온정주의에서는 사랑의 힘이 정의의 손길을 일정부분 차단할 수 있는 위험성 또한 확인할 수 있었다. 따라서 차라리 사랑과 정의, 그 양자를 함께 보듬어 양립의 가능성을 모색하는 것이 건강한 미래 사회를 위해 더 필요하다고 여겨졌다. 여기서 우리는 폴 리쾨르의 표현처럼 '상황에 맞는 도덕적 판단'이 요구되는 '사려 깊은 균형'에서 그 양립 가능성을 확인했다. 이러한 이상적인 상황은 차원 높은 시민의식이 발휘되는 연대의식과 상호 배려, 도스토예프스키처럼 고통을 함께 하는 연민 등이 개입된 사랑의 형태가 분배적 정의 원리와 결합되었을 때 실현될 수 있을 것이다. 알베르 카뮈가 정의만을 추구하다 결국 현실을 직시하고 자비의 필요성을 언급할 때 이미 그는 이러한 상황에 따른 도덕적 판단을 내렸다고 할 수 있겠다. 결국 사랑은 정의를 지켜주고, 정의는 사랑을 현실화하는 데 기여한다. 정의는 초윤리적 사랑을 도덕 범주로 환원하는 데 일조하며, 사랑은 정의가 한껏 힘을 발휘할 수 있도록 도와주는 역할을 한다.

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.
