  • The First bentwood chairs in the world, called "winsor chairs" were made by British craftsman in the 17th century. Since then, from the start of NO.14 using solid bentwood by 19th-century German Michael Thonet, furniture making techniques such as Bent knee, Y-leg, X-leg- were developed based on Llaminated bentwood made by Alvar Aalto of Finland in the 20th century. In the 20th century Charles Eames of the United States studied Molded plywood, using plywood to produce a variety of furniture and during the 17~20 century a variety of Bentwood were developed. Coming into the 21st century, American Matthias Pliessnig and Phil Seaton worked with past Bentwood designs, developing Bentwood further by adapting Bentwood's know-how and IT technology. Science and technology evolved and Reholz of Germany developed technology which can mold three-dimensional wood using a new matarial called 3D-veneer, In the past only plastic or metal could be moulded 3 dimensional but now beautiful wood grain patterns can be molded by utilizing this technology. Also this is comparable with the past two-dimensional molding technology. In this Sustainable Design techniauses era, Bentwood fused with IT technology has great potential as a high-tech and eco-friendly techniche.

  • In 1536, two Piedmontese merchants set up workshops in Lyons, and Henri IV encourged further development later in the 16th century. The development of Lyons as a centre of the silk weaving industry was helped by the perfection of drawloom weaving technique there in 1605 by Claude Dangon. In the 17th century, the French silk industry could finally compete with the dominance of the Italian silk trade. The French silk industry was promoted in the mid-17th century under Louis XIV's minister Colbert. In 1667, he published an ordinance creating La Grande Fabrique, a corporation for craftsmen within the silk industry, and Lyons became the undisputed French silk capital. Under Louis X IV, France was becoming the dominant force in Europe in matters of fashion and style. The major innovation of weaving was the Jacquard head attachment, which provided a mechanical means of raising warp threads by a series of punched cards. The are nouveau style did not have much impact on French silk design at the end of the century. Silk manufacturers began to collaborate with haute-couture designers such as the House of Worth. This collaboration with the burgeoning Paris haute-couture industry continued into the 20th century and safeguarded the future production of silk textiles in France.

  • The gastrointestinal tract forms the largest surface in our body with constantly being exposed to various antigens, which provides unique microenvironment for the immune system in the intestine. Accordingly, the gut epithelium harbors the most T lymphocytes in the body as intraepithelial lymphocytes (IELs), which are phenotypically and functionally heterogeneous populations, distinct from the conventional mature T cells in the periphery. IELs arise either from pre-committed thymic precursors (natural IELs) or from conventional CD4 or CD8αβ T cells in response to peripheral antigens (induced IELs), both of which commonly express CD8α homodimers (CD8αα). Although lineage commitment to either conventional CD4 T helper (Th) or cytotoxic CD8αβ T cells as well as their respective co-receptor expression are mutually exclusive and irreversible process, CD4 T cells can be redirected to the CD8 IELs with high cytolytic activity upon migration to the gut epithelium. Recent reports show that master transcription factors for CD4 and CD8 T cells, ThPOK (Th-inducing BTB/POZ-Kruppel-like factor) and Runx3 (Runt related transcription factor 3), respectively, are the key regulators for re-programming of CD4 T cells to CD8 lineage in the intestinal epithelium. This review will focus on the unique differentiation process of IELs, particularly lineage re-commitment of CD4 IELs. [BMB Reports 2016; 49(1): 11-17]

  • Implantation of an embryo occurs during the mid-secretory phase of the menstrual cycle, known as the "implantation window." During this implantation period, there are significant morphologic and functional changes in the endometrium, which is followed by decidualization. Many immune cells, such as dendritic and natural killer (NK) cells, increase in number in this period and early pregnancy. Recent works have revealed that antigen-presenting cells (APCs) and NK cells are involved in vascular remodeling of spiral arteries in the decidua and lack of APCs leads to failure of pregnancy. Paternal and fetal antigens may play a role in the induction of immune tolerance during pregnancy. A balance between effectors (i.e., innate immunity and helper T [Th] 1 and Th17 immunity) and regulators (Th2 cells, regulatory T cells, etc.) is essential for establishment and maintenance of pregnancy. The highly complicated endocrine-immune network works in decidualization of the endometrium and at the fetomaternal interface. We will discuss the role of immune cells in the implantation period and during early pregnancy.

  • Trifoliate orange seed extracts (TSEs) were made using either distilled water (TW), ethanol (TE), or n-hexane (TH), to measure total polyphenol contents, DPPH and ABTS radical scavenging activities, and anti-complementary activity. The results showed that the total polyphenol content showed higher value at TE (235.24 ${\mu}g/mL$, p<0.05) than those of TW (132.65 ${\mu}g/mL$) and TH (165.44 ${\mu}g/mL$) at 10 mg/mL and TE exerted the highest DPPH radical scavenging activity (61.77%, p<0.05), which occurred in the following order: TE TW (56.87%)>TH (39.78%). The results of ABTS radical scavenging activity showed that TW (34.26%) and TE (31.81%) showed similar activities, which were higher than TH (12.74%, p<0.05). Anti-complementary activity of TE (61% at 500 ${\mu}g/mL$) showed a higher activity when compared with the positive control (60% at 1,000 ${\mu}g/mL$) polysaccharide-K (PSK), a known immuno-active polysaccharide from Coriolus versicolor. Consequently, among TSEs, TE is a byproduct from trifoliate orange and could be an important source of dietary polyphenolic antioxidant compounds and immunopotentiating activity, including complement activation.

  • Entrepreneurship is recognized as an essential education in start-up education. However, domestic studies on entrepreneurship in developing countries are extremely rare. The purpose of this study is to compare the importance of entrepreneurship and the perception of implementation of Korean and Nepalese farmers, and to seek a start-up education strategy based on the results. As a result of the study, first, there was no difference in the importance of entrepreneurship in the 6th industry between two countries, but the degree of entrepreneurial spirit performance was high in Nepalese farmers. Second, in terms of the difference between the importance and execution of the 6th industry entrepreneurship, Korea had lower performance than importance in all factors, and Nepal had higher importance than implementation in innovation, initiative, cooperation, and networking capability. Third, in the difference between the importance and the degree of implementation in each country, the level of implementation was uniformly lower than that of importance in Korea, but the height of the Nepalese farmers was not uniform. The results of this study, which studied entrepreneurship in Korea and Nepal, contribute greatly in terms of promoting the national economy by creating new added values.

  • The Silk Road usually implies a network of trade and communications that stretched from east to west and connected China and the countries of the Far East via Central Asia and the Middle East to the eastern Mediterranean, or through the northern coast of the Caspian Sea and the Volga basin to the Black Sea coast. However, at certain historical stages, a network of maritime and overland routes stretching from north to south, commonly called the Volga-Caspian trade route, also played a significant role in international trade and cultural contacts. The geopolitical realities of the early Middle Ages relating to the relationship of Byzantium, the Sassanid Empire, and the West Turkic Khaganate, the advance of the Arab Caliphate to the north, the spread of Islam in the Volga region, the glories and fall of the Khazar State, and the Scandinavian campaigns in the Caucasus, closely intertwined with the history of transport and communications connecting the north and south through the Volga-Caspian route. In a later era, the interests of the Mongolian Uluses, and then the political and economic aspirations of the Ottoman Empire, the Safavid State, and Russia, collided or combined on these routes. The article discusses trade contacts existing between the north and the south in the 15th and first half of the 17th century along the routes on the western coast of the Caspian Sea.

  • The 4th industrial revolution technology has brought many changes not only in human life but also in the industrial field. ICT such as 5G and artificial intelligence and convergence/complex systems such as drones and robots are convenient for humans, and automation of all processes in the industrial field. However, these advanced information and communication technologies also have adverse functions. As advanced ICT was incorporated into military and terrorist weapon systems, more powerful and highly destructive weapon systems began to be developed. In particular, by applying advanced ICT to the production and use of terrorist tools, the terrorist method became more sophisticated and caused more damage. In this paper, we derive advanced ICT that can be abused according to the terror patterns in the 4th industrial revolution era, and present a method that is applied from preparation to execution of terrorism. The abuse of advanced ICT makes terrorism more stealthy and subtle, and increases its destructive power.

  • The aim of this study is to investigate the wound healing effects of the Opuntia ficus-indica. Four full-thickness skin wounds(2.5 cm × 2.5 cm) were made in different areas on the back in each of five dogs. Two wounds were used for wound size measurement and two for skin biopsy. The ten full-thickness wounds were treated with the extract of Opuntia ficus-indica, and the ten full-thickness wounds were treated with normal saline. The wound areas were measured every other day for three weeks after wounding. Statistical analysis was performed with the paired t-test. The wound healing rates were 32.9±4.0%, 28.2±7.1%, 42.2±4.1%, 55.0±4.3%, 76.6±2.8%, 86.8±2.3%, 94.0±1.l%, 97.3±0.8%, 99.3±0.3%, 99.8±0.2%, 100.0±0.0% in the experimental group, and 18.0± 8.2%, 13.S± 11.6%, 15.2±6.1 %, 36.9±8.8%, 62.4±4.1%, 80.0±2.3%, 86.0±1.4%, 94.0±0.9%, 96.9±0.8%, 97.8±0.3%, 99.7±0.1% in the control group on the 1/sup st/, 3/sup rd/, 5/sup th/, 7/sup th/, 9/sup th/, 11/sup th/, 13/sup th/, 15/sup th/, 17/sup th/, 19/sup th/, 21/sup st/ day. On the 17/sup th/ day, the wound closed above 99.9% in 1 dog of the experimental group. On the 19/sup th/ day, the wound closed above 99.9% in 3 dogs of the experimental group. On the 21/sup st/ day, the wound closed above 99.9% in 5 dogs of the experimental group, and 1 dog of the control group. The wound healing period was shortened by 2 to 4 days in the experimental group as compared with the control group. The tensile strength was 4,508±513 g/㎠ in the experimental group and 2,772±400 g/㎠ in the control group on the 21/sup st/ day after wounding. The tensile strength was significantly higher in the experimental group than in the control group(p< 0.05). Inflammation rapidly spread and disappeared in the experimental group but not in the control group. Fibroblast and vascularization were found on the 5/sup th/ day in both group and increased only in the experimental group on the 9/sup th/ day. The firs finding of epithelialization was on the 13/sup th/ day in the experimental group and the 21/sup st/ day in the control group. A significantly higher wound healing rate(p< 0.05), tensile strength(p< 0.05) and better histopathological findings were observed in the experimental group than in the control group throughout the experimental period. These results suggest that topical application of Opuntia ficus-indica extract can promote wound healing in dogs.
