  • We report the new threadlike structures outside the blood vessels of mice. For this, we developed an in-situ searching method of the structure by vital staining with the dye of acridine orange and using a fluorescent stereomicroscope designed specifically for this purpose. We consider that the newly found threadlike structure might be rediscovery of the extra-vascular Bonghan duct which was reported in 1963 by Bonghan Kim.

  • Cationic polymerization of isobutyl vinyl ether using various metal halides was examined in toluene in the presence of an added base at $0^{\circ}C$. In conjunction with an appropriate weak base such as ethyl acetate or 1,4-dioxane, all metal halides but $FeBr_{3}\;and\;GaCl_{3}$ led to living cationic polymerization. The polymerization rates varied as follows: $FeBr_{3},\;GaCl_{3}\;>\;FeCl_{3}\;>\;SnCl_{4}\;>\;InCl_{3}\;>\;ZnCl_{2}\;>>\;AlCl_{3},\;HfCl_{4},\;ZrCl_{4}\;>\;EtAlCl_{2},\;BiCl_{3},\;TiCl4\;>>\;SiCl_{4}\;>\;GeCl_{4}$. This order partially corresponds to that of the equilibrium constant in the formation of a carbocation from a chloroalkane in the presence of a carbonyl compound. With extremely active Lewis acids, such as $FeBr_{3}\;and\;GaCl_{3}$, the use of a stronger base, THF, was required to achieve living polymerization.

  • In the resultant period of architectural transition and a tendency towards unthinking formalism, it is all the more important for designers to question the meaning of their actions and their role in society. Modern architects were convinced that their visions were reality, their ideas truth. Yet this assumption is was the fundamental issue, for what reality and how is it perceived? Harries argues a rediscovery of a language of natural symbols, which might help create buildings that are experienced as necessary rather than arbitrary. These symbols are said to express the essential patterns of human existence in the world. In the Frank Lloyd Wright's works, the uniqueness of his architecture lies in its expression and interpretation of nature and people's existence in the world. This study is intended to be an investigation of the nature of physical expression and perception of the reality known, and to seek to present Wright's philosophy of house design in relation to nature and non-arbitrary architecture. Finally this paper concludes that the architectural expression of expressions of Wright's houses are timeless and full of lift, and these built qualities are necessary and could not readily be otherwise.

  • Purpose: The purpose of this study was to describe experiences of sexual life among Korean women with breast cancer. Methods: Data were collected by focus group and individual tape-recorded interviews. The data were analyzed using qualitative content analysis. Results: Participants were 13 women who had stage I, II, or III breast cancer. Four major categories were discovered. "Not interested in sexual life at all" in which participants described their struggle to live while avoiding sexual life during initial stages of disease. "Sexual life that could not go back to previous normal life" in which participants described how they began to recognize many problems related to their sexual life resulting from the loss of femininity and pain during intercourse. "Dangerous marriage due to no sexual life" in which participants illustrated how no or unsatisfactory sexual life threatened their entire marriage and family life. Finally, "rediscovery of sexual life as a vital element in life" in which participants described how, with support from their spouse, they came to realize that sexual life was an important and vital part of their life. Conclusions: The results of this study could help in developing-educational programs to improve sexual well-being of women with breast cancer and their spouses.

  • Nefopam (NFP) is a non-opioid, non-steroidal, centrally acting analgesic drug that is derivative of the nonsedative benzoxazocine, developed and known in 1960s as fenazocine. Although the mechanisms of analgesic action of NFP are not well understood, they are similar to those of triple neurotransmitter (serotonin, norepinephrine, and dopamine) reuptake inhibitors and anticonvulsants. It has been used mainly as an analgesic drug for nociceptive pain, as well as a treatment for the prevention of postoperative shivering and hiccups. Based on NFP's mechanisms of analgesic action, it is more suitable for the treatment of neuropathic pain. Intravenous administration of NFP should be given in single doses of 20 mg slowly over 15-20 min or with continuous infusion of 60-120 mg/d to minimize adverse effects, such as nausea, cold sweating, dizziness, tachycardia, or drowsiness. The usual dose of oral administration is three to six times per day totaling 90-180 mg. The ceiling effect of its analgesia is uncertain depending on the mechanism of pain relief. In conclusion, the recently discovered dual analgesic mechanisms of action, namely, a) descending pain modulation by triple neurotransmitter reuptake inhibition similar to antidepressants, and b) inhibition of long-term potentiation mediated by NMDA from the inhibition of calcium influx like gabapentinoid anticonvulsants or blockade of voltage-sensitive sodium channels like carbamazepine, enable NFP to be used as a therapeutic agent to treat neuropathic pain.

  • The family Peronosporaceae, an obligate biotrophic group of Oomycota, causes downy mildew disease on many cultivated and ornamental plants such as beet, cucumber, grape, onion, rose, spinach, and sunflower. To investigate the diversity of Peronosporaceae species in Korea, we performed morphological analysis for dried plant herbariums with downy mildew infections by two largest genera, Peronospora and Plasmopara. As a result, it was confirmed that there are five species of Peronospora and two species of Plasmopara, which have been so far unrecorded in Korea, as well as rarely known in the world; Pl. angustiterminalis (ex Xanthium strumarium), Pl. siegesbeckiae (ex Siegesbeckia glabrescens), P. chenopodii-ambrosioidis (ex Chenopodium ambrosioides), P. chenopodii-ficifolii (ex Chenopodium ficifolium), P. clinopodii (ex Clinopodium cf. vulgare), P. elsholtziae (ex Elsholtzia ciliata), and P. lathyrina (ex Lathyrus japonicus). In addition, their phylogenetic relationship was inferred by molecular sequence analysis of ITS, LSU rDNA, and cox2 mtDNA. By rediscovering the seven missing species and barcoding their DNA sequences, this study provides valuable insights into the diversity and evolutionary studies of downy mildew pathogens.

  • The Taesangugeupbang (Emergency Prescriptions for Childbirth) is a medical text written by Li-Chengong of China in the early 14th century. It incorporates forms of obstetrics and gynecology in use in the Chosun Dynasty and is quoted in the Hyangyakjibsungbang (Compendium of Prescription from the Countryside), the Euibangyoochui (Classified Collection of Medical Prescriptions), and the Taesanjibyo (Collection of Essentials for Childbirth). The recent rediscovery of Taesangugeupbang manuscripts in Japan has enabled full-scale research of this text. This article is based on a study of these manuscripts and attempts to synthesize the text through the various documents. The article suggests that: (1) critical texts for understanding the Taesangugeupbang include the Uijeoggo (A Review of Medical Books), the Euibangyoochui, and the Taesanjibyo; (2) there is a possibility that the Taesangugeupbang had disappeared from use in Joseon by the late 15th century; (3) the Taesangugeupbang complemented the treatment regimen of other texts and influenced the development of early Chosun ophthalmology; (4) The Taesangugeupbang is quoted in many Joseon's medical texts and is related to the author's mentor.

  • Over the past few years, due to the climate change of the earth, the Arctic's sea ice cover is undergoing a historic transformation - thinning, extent reduction in all seasons, and mitigation in the area of multi-year ice in the central Arctic Ocean. These changes allow for increases in maritime access throughout the Arctic Ocean and for potential longer seasons of navigation and possibly transarctic voyage in the summer. These changes also allow more exploration for oil, gas, and other minerals. The Arctic is now an archetype of the complex, multi-dimensional global problems of the twenty-first century. Military security, environmental security, and economic security interact. The potentially enormous economic stakes, sufficient to change the strategic balance among the states of the region, set off competitive pressures for national advantage. Korea, which is heavily dependent upon the sea lane in terms of transportation of its exports and imports, is very much interested in the Arctic sea routes. Korea believes that the Artic sea route, particularly the Northern Sea Route (NSR), could serve as a new useful sea lane, which will enable shorter times between East Asia and Europe, thus resulting in substantial cost saving for ship operators. In addition to shipping, Korea is interested in other Arctic-related maritime industries. Korea, as a leading shipbuilder in the global market, is interested in building ice breakers, drill ships, and other vessels which can contribute to safe operation in Arctic resource development and exploration. Korea, as one of the future stakeholders in Arctic maritime activities, should be ready to foster international cooperation in the region.
