This paper describes the mechanism of information processing in the nervous system through neuron pool model which is consisted of six single neural models. In the neuron pool model, summation characteristic of stimulus satisfies those of real nervous system and output impulse rate increases linearly to the input stimulus. Occlusion phenomena of the neuron pool model is approached to those of real nervous system and also if the threshold potential within sutlirninal fringe is increased, facilitation phenomena appreared. Therefore, the results of this study suggest that we can construct large neuron pool with many single neural models and verify the mechanism of information processing in the wide part of nervous system.

현탁중합에 의하여 다공성 스티렌-디비닐벤젠 공중합 수지입자를 제조하였으며, 그 수지입자는 가교제인 디비닐벤젠과 세공형성제인 톨루엔 농도가 각각 30wt% 이상일 때만 다공성을 나타내었다. 다공성 수지입자의 비표면적은 디비닐벤젠과 톨루엔의 농도에 따라 증가하였으며, 진한 황산으로 황산화시켰을 때 비표면적은 감소하였다. 에틸아세테이트와 1-프로판올의 에스테르화 반응에서 황산화된 수지촉매의 활성은 가교도에 따라 증가하였다. 수용액 중 sodium dodecylbenzene sulfonate의 흡착에서 다공성 수지입자의 표면적에 따라 흡착량이 증가하였다. Porous resin beads of poly(styrene-co-divinylbenzene) have been prepared by suspension polymerization. The bead could be made porous in the region above 30wt% of the crosslinking agent(divinylbenzene) and the porogenic agent(toluene), respectively. The specific surface area of porous beads increased with increasing the concentrations of divinylbenzene and toluene. The specific surface area of the porous resin bead decreased, when sulfonated with concentrated sulfuric acid. The catalytic activity of sulfonated resin catalysts increased with increasing the degree of crosslinking in the liquid-phase reesterification of ethyl acetate with 1-propanol. The adsorbed quantity of sodium dodecylbenzene sulfonate in an aqueous solution also increased with increasing surface area of porous resins.

We as a civil investment enterprise have been constructing In-cheon International Airport Railway which is a transportation means to approach In-cheon International Airport. In this alignment, a section between the Seoul station and Ka-joa follows the existing Yong-san line at the center of Seoul city and traverses Seoul subway 2,5,6 lines. So we planned that the alignment would have the shallowest depth to lie under Kyung-eui line and above the airport railroad. The alignment is planned to construct an open-box structure only 3.6m apart from the subway line 5 tunnel structure and construct the open-box structure 0.7m apart from the subway line 2 box structure. In the line planning, we investigated both the security of the existing subway structures during and after construction and the stability and workability between newly structured tunnel structures with three dimensions numerical analysis methods. Also we raised the reliability of design verification which was achieved by specialty society"s review on the planned construction method.

역사와 고구려 드라마 ‘연개소문’

김용만(Kim Yong-man) 고구려발해학회 2007 고구려발해연구 Vol.28 No.-

Everywhere we look, it is apparent that television dramas have become a cultural product enjoyed by the masses, a phenomenon that has become a symbol of pop culture today. But historical dramas have set themselves apart from other dramas by virtue of the ability provide historical knowledge to the audience, and naturally, has an influence that far outstrips any history book. It is because of this that no serious historian can stay ignorant or indifferent to production of historical dramas. Because of its portrayal of a controversial historical character from Korean history and the great war between the ancient Korean state of Koguryo against Sui and Tang dynasties of China, Korean audiences flocked to watch 〈Yongaesomun〉, a 100-episode historical drama produced and broadcast by Seoul Broadcasting System from July of 2006 to June of 2007, which maintained a high viewer rating during the duration of the broadcast. Yet despite declaration from the producers of 〈Yongaesomun〉 that their drama would faithfully take actual historical events into account, the drama never quite lived up to that promise. The problems with 〈Yongaesomun〉 are manifold, but can be divided to four major aspects. The first and the most outstanding error concerns the arrangement of the script itself. Aside from episodes 1 and 2, which formed the introduction, episodes 3 to 54 formed the first half, and the rest (episodes 55-100) formed the second. Yongaesomun himself, the namesake for the entire drama, was actually the main character only ill the second half. The writer's biased interest in a specific part of history made Yangdi of Sui the central figure if the first half, with Yongaesomun relegated to a minor role. Such an arrangement is an error of monumental proportions, for Yangdi and Yongaesomun have never personally met each other and, more importantly, lived generations apart. A mistaken attempt to connect the two characters mixed up the actual order of historical events as well as seriously skewing the relationships between the major characters. A warped timeline became a critical error that doomed any claims about 〈Yongaesomun〉 as a serious historical drama. The second error is no less glaring, in that it bent basic historical fact. Aside from the changing of order of historical events mentioned above, the roles assigned to a number of characters revealed wide discrepancy with the actual role they played in history. Though there is room for imagination or certain amount of fiction in a drama, a historical drama is different in that the basic facts that form the background of the story must adhere to the truth. Anything that allow pieces of fiction that contradict basic fact to enter the story line, is at best historical fusion or fantasy, and has no right to be called a historical drama. Third, the drama was dripping with fatalism and the writer's hero worship. The fatalism that was revealed many times in the drama, which claims that there are things in history that happen no matter what happens, is perhaps the greatest obstacle to proper understanding of history. In addition, excessive hero worship, overemphasis on masculinity, and a historical perspective bordering on chauvinism obviously prevented the writer from objective understanding of why things happened the way they did and why other things did not. Fourth, the writer exhibited an appalling lack of creativity by utter inability to bring new characters to life, rather relying on heavy borrowing from other literature. It was highlighted by the fact d1at personalities and appearance of many characters did not resemble the people of Koguryo, but instead were copied from epics from other countries, Writers of good dramas must consider research into the diversity of human nature his or her main responsibility, to discover the various natures and characters in real life. By choosing to borrow and copy rather than create characters, a historical drama supposedly abo
