成(성) 연간기획 김영철 : 지방공기업법개정으로 지방공사채 "특수채" 지위부여
김영철 한국지방재정공제회 2014 지방재정 Vol.2014 No.3
지난 6월 3일 지방공기업법 일부 개정법률이 시행되었다. 이번 일부 개정법률에는 그 동안 안전행정부와 지방공사의 숙원이었던 공사채의 특수채 지위 부여가 담겨있다. 이번 법개정으로 지방공사들은 앞으로 채권시장에서 금리수준이 회사채에 비해 낮게 형성되고, 집합투자자의 투자한도가 상향되면서 지방공사의 부채감축 및 재정건전화에 기여할 것으로 기대된다.
Ca2+-activated K+ Current in Freshly Isolated c-Kit Positive Cells in Guinea-pig Stomach

This study was designed to isolate Ca2+-activated K+ current (IKCa) and elucidate its physiological significance in freshly isolated interstitial cells of Cajal (ICCs) of guineapig stomach. Single ICC was freshly isolated by enzymatically dissociating from myenteric border of gastric antrum free of circular muscles, and conventional wholecell voltage clamp technique including immunohistochemical techniques were employed to characterize the cells: In myenteric border of gastric antrum, ICC-MY (ICCs from myenteric border) were detected by immunohistochemical reactivity, and single ICC-MY which has many branches was immunohistochemically c-Kit positive. Under K+-rich and 0.1 mM ethylene glycol-bis (2-aminoethyl ether)-N,N,N′,N′-tetraacetic acid pipette solution, ICC produced spontaneous inward current (-256±92.2 pA). When step-depolarizing pulse from -80 to +80 ㎷ was applied at holding potential (Vh) of -80 ㎷, voltage-dependent outward currents were recorded with superimposed spontaneous transient outward currents (STOCs). Both STOCs and outward currents were reversibly affected by tetraethylammonium chloride (TEA) and iberiotoxin (IbTX); 2 mM TEA and 200 nM IbTX completely abolished STOCs and significantly inhibited outward K+ current over the whole potential range tested for current/voltage (I/V ) relationship. In addition, TEA delayed repolarization phase of spontaneous inward current. The present results indicate the presence of IKCa in a single ICC, and it might be involved in regulation of repolarizing phase of spontaneous inward current in guinea-pig stomach.
Characteristics of Light Transmission Through Nano-Apertures on Pyramidal Probes
김영철,최성수,D. W. Kim,M. Joo,M. J. Park 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.3
Extensive studies, including 3-D simulations and experimental measurements, were carried out to investigate the effect of the aperture diameter on light transmission for a cantilever-based pyramidal probe. A series of Au-coated nano-apertures were fabricated at the apexes of pyramidal probes and the transmission efficiency of light through those apertures was measured and compared with theoretical results. The relationship between the aperture diameter and the transmission efficiency, both in simulations and experiments, can be divided into three groups depending on the aperture diameter. When the aperture diameter becomes very small (d/$\lambda <$ 1/10) compared with the input wavelength, the transmission efficiency follows Bethe's theoretical result. It increases rapidly when the diameter is around half the wavelength of the input laser and finally approaches the classical expectation with increasing diameter above that wavelength.

This study aims at the division of genre of N.Korean poetry and the characteristics of N.Korean poetry. N.Korean poetry divide genre into lylic, hymn, elegy, satire, geongronsi(정론시), gyehunsi(교훈시), dansangsi(단상시), punggyungsi(풍경시), chulrisi(철리시),etc. by the meaningful standard. N.Korean poetry are not isolated the poem from the song and keep the mode of singing poetry for the function of agipro, for example, gasa(가사) hapchangsi(합창시), revolutionary ballads. Lylic concludes hymn, satire, geonronsi, byugsi(벽시) inclsively and they show the political tendency. N.Korean lylic is used as general concept of poetry. N.Korean poetry point toward the pure lylic of life and nature remarkbly and diminish the ideological tendency since 1980's. Epic is the main genre among the N.Korean poetry, because it satifies the need of narrative mode for the anti-Japanese literature and the creation of chieftain image.
