돈윤승,김상욱 서울市立大學校 1989 論文集 Vol.23 No.-

Melt viscosity of the SAN copolymer added stearate type and amide type lubricant was measured at two different temperatures and at 10²∼ 10⁴sec¹ shear rate. The result was decrease of melt viscosity according to lubricant, but the behavior of melt viscosity at 1wt% content and or more addition of lubricant was same. And amide type lubricant was observed to affect shear stress, melt viscosity of the SAN copolymer more deeply then stearate type and 1wt% content was observed as enough amount.

The possibility that conflicts and disputes surrounding the NIMBY facility construction among local governments related to the adjacent boundary areas which are rising as important policy issues is growing with the boundary expansion of traffic and life zones and spatial developmental expansion of cities. Conflicts in the formative project on the NIMBY facilities between Bucheon city and Guro-gu are also a case for conflict among fundamental(lower level) local governments appearing out of the difficulty of site selection in the perspective of spatial limitations in the restricted land use aspect. This research hopes to understand the NIMBY facility construction implementation project within the fundamental local governmental relations on the local governmental level while, also finding out how objective resolutive conditions are dealt with in the negotiation mechanism among actual fundamental local governments. It is hoped to examine through which strategies such cooperation/conflict strategies discussed in such negotiation mechanisms are useful for cooperative agreement extractions among local governments. Besides, this research is on the stance that it is most desirable for each strategy used in cooperative mechanisms to be actively understood through spontaneous negotiation courses by fundamental local governments which are the concerned party of conflicts; however, in cases not adjusting or solving conflicts independently, it cannot but help to depend on the adjustable role of regional council or the central government who are in the position of a 3rd party. However, in order to establish a negotiation culture such as the discussion of reinvigoration for the formation of mutual trust and conflict remedy among local governments, it is seen that the construction and practice of creative negotiation strategies that fundamental local governments, the concerned party, intend to solve spontaneously on their own are very important. 본 연구는 지방정부 수준에서의 비선호시설 건립 추진사업을 기초자치단체간 관계 속에서 파악하고자 하 며, 또한 객관적인 해결조건들이 실제 기초자치단체간의 협상기제에서 어떻게 다루어질 수 있는지를 알 아보고자 한다. 이러한 협상기제에서 논의되는 협력･갈등전략이 과연 지방자치단체간의 협력적 합의도출 을 위해 어떠한 전략이 유용한지를 살펴보고자 한다. 더불어 본 연구에서는 협상기제에서 구사되는 각각 의 전략들이 갈등의 당사자인 기초자치단체에 의한 자율적인 협상과정을 통해 적극적으로 모색되는 것이 가장 바람직하다는 입장이며, 다만 자율적으로 갈등을 조정 및 해결하지 못한 경우에는 제3자의 입장에 있는 광역지방정부나 중앙정부의 조정적인 역할에 의존할 수밖에 없다고 본다. 하지만 기초자치단체 간 또는 광역자치단체 간의 상호신뢰 형성과 갈등해결을 위한 토론 활성화 등의 협상문화가 정착되기 위해 서는 당사자인 지방자치단체가 자발적으로 해결하려는 창조적 협상전략의 구축과 실천이 매우 중요하다 고 본다.

근대국어의 어간말 자음군 표기연구

I have up to now observed the consonants cluster script at the Final of a word-stem dividing the voiceless sound model and the voiced. There are ㄵ, ㄶ, in ㄴ model, meanwhile ㄺ, ㄻ, ㄼ, ㄾ, ㄿ, ㅀ in ㄷ model. However among these models ㅅㄱ has instead been eliminated and newly added ㄽ in modern Korean. The stem of a word has usually been declared in front of a vowel sound and it has also been marked as a unit of a detachment or as a split consonant in preceding consonant. On the other hand such stems of a word as ㄺ, ㄹㅂ in consonanst cluster has not only been marked as a unit of split, but it has been declared as ㄺ, ㄼ as well. These stems of words and consonants clusters include modified variations accompanying components of phonetic circumstances, but only ㄺ, ㄼ shows irregular and primary shifting. Accordingly the consonant cluster showing irregular substitution at the stem of a word has been marked as a unit of detachment, regardless of the phonetic circumstances. Besides the stem of a word and sequence of the consonants has frequently shifted in the wrong order. Meanwhile pause or modified variation particularly demonstrating irregular substitution at a word's ending has been marked as a unit of coalition, but it has also been scripted either in detachment or as the second consonant cluster as ㄻ has been elimintated at the preceding a consondnt-ending and pause. In case of the elimination, a consonant at a word's ending has as a usual been occurred at the circumstances of voiced sound. Especially the consonant cluster in the voiceless at the Final of a word-stem eliminate the second consondnt or pause, in which the preceding consonant still firmly remained.

Angiography법을 이용한 백서유경피판의 혈행양상에 대한 경시적 관찰

유동제인 pentoxifyline과 혈관확장제인 dipyridamole 투여가 피판 생착율 증가에 미치는 영향을 혈관의 분포변화에 초점을 두어 조직학적 그리고 묵즙 주입 조영법으로 관찰한 바 다음과 같은 결과를 얻었다. 묵즙 angiography 소견상, 피판 및 주변 혈관의 확장상 및 문합 정도가 실험 2군에서 가장 양호하였고, 다음으로 실험 제1군, 대조군순이었다. 조직학적 소견은 묵즙을 이용한 angiography법의 소견을 뒷받침하였다. 혈관의 시간별 변화는 각군 유사하였으며, 술후 3일째에 혈관들은 피판 장축방향으로 서로 문합되어 분포하였으나, 술후 10일째에는 정연성이 소실되면서 여러방향으로 복잡한 혈관망을 이루었고, 혈관의 숫적증가를 보였다. 술 후 21일째에는 혈관의 확장상의 소실과 더불어 조밀한 세소혈관망이 구축되었고, 피판 측방에서 기시하는 혈관들이 피판 중앙부로 부터 장축방향으로 주행되었다. Angiography is a technique which shows detalied vascular construction and patterns of organs at the level of the small vessels and capillaries. The relation between blood flow and skin flap survival was evaluated with India ink angiography. 45 rats were divided into 3 groups. Caudally based random pattern flaps were designed on the back of the rats, and control group animals received twice-daily an intraperitoneal injection of 0.2㏄ normal saline solution for 7 days after surgery. Group I rats were treated with intraperitoneal injection of pentoxifyline 20㎎/㎏ every 12 hour for 7 days after operation. Group Ⅱ rats were treated with intraperitoneal injection of diphyridamole 0.3㎎/㎏ every 12 hour for 7 days before surgery and 7 days after surgery and pentoxifyline 20㎎/㎏ as same as group Ⅰ. The results were as follows: In histopathologic observation. on the 3rd day after flap operation. vasodilation and increase in vessel number was observed. On the 10th day after flap operation, vasodilation and increase in vessel number was observed. On the 10th day after flap operation, decrease in vessel diameter with thickening wall was observed and on the 21th day after flap operation, vasoconstriction and organization process was observed. In india ink angiographic obsevation, centrally running blood vessels were observed from flap base to central area and complicate vessel network formation originating periphery which surrounded flap was observed, chronologically.

There are many things to be desired in studies on the History of the Korean language, and there is no fixed chronological division of the Korean language history. I do not mean to sat that there has been no attempt to divide the development of the Korean language chronologically. But the division so far has been made from the viewpoint of extreme intra-linguistic or extra-linguistic position. With present insufficient references and studies on the History of the Korean language, it is next to impossible to draw chronological division by intra-linguistic aspects. And again extra-linguistic aspects along can not serve as sufficient milestones for the division. Therefore an attempt will be made in this paper to present a reasonable frame of reference for chronological division of the Korean language development by giving prior considerations to the studies on the History of the Korean language and by employing the knowledge of peripheral studies. Among those peripheral studies, particular attention will be give to History and its time division. 1) All of the available references will be thoroughly studied. And the accumulated knowledge from studies of comparative linguistics, of dialects, and of general linguistics will be used in this paper. 2) Uniformity in terminologies indicating each divided period is badly needed. I suggest that the word, CHUNG KI O, be used to refer to Middle Age Korean, and that SANG GO O and CHUNG GO O be used as a subdivision of KO DAE O. When we adopt terminologies used in the time division of History, it is desirable that the period indicated by the words should be identical in History and in History of the Korean language. 3) Chronologica division centered on political or cultural history demarcated by emerging or perishing of kingdoms may not be useful. ⅰ) Unification of Three Kingdoms by Shilla is considered to be important ⅱ) Mongolian invasion at the end of Korea Dynasty has serious influence in the Korean language development. ⅲ) Creation of the Korean Alphabets can not be the dividing point. ⅳ) IM JIN OE RAN and the kabo Kyongjang are important milestones in the chronological division. 4) Overall consideration will be give to the inducted results from studies on the history of Phonology, of Lexicon and of Grammar 5) Synchronic studies on the Korean language in each divided period should be reinforced. 6) Some materials extracted from few references can never be overemphasized.

The rabbit sinoatrial node was cut into small pieces which wew 0.5×0.5㎜ in sizes, electrically insulated and could be partitioned into central and peripheral areas. Glass microelectrodes were impaled into both areas and transmenbrane potentials were recorded in order to observe the changes in effects of higenamine on the both areas by the addition of TEA, Cs^+ and Ba^2+ or pretreatment of propranolol. 1. Effects of higenamine were more prominent in high K^+ concentration than those in the low K^+ concentration. 2. TEA induced the decrease in the spontaneous firing rate and the prolongation in the action potential duration which could be reversed by higenamine. 3. Ther were prominent decrease of spontaneous firing rate and the prolongation in the action potential duration in peripheral area with the uncrease of Cs^+ concentration. Higenamine reversed the decrease of spontaneous firing rate in some degree. 4. There were significant decreases of spontaneous firing rate, amplitude of action potential and maximum diastolic potential by the Ba^2+ in peripheral area. Effects of Ba^2+ were reversed by higenamine in central area. 5. The effects of higenamine were completely blocked by the pre-treatment of propranolol. 6. There was no effect of higenamine of the Na-K pump activities. The above results could be interpreted as effects of higenamine were mediated by the chamge of calcium ion current rether than those of the potassium ion current in sinoatrial nodes.

In this paper we fuzzyfy the solutions of the linear second order ordinary differential equations with constant coefficients and define fuzzy solutions to O.D.E. appropriately. Moreover, we compare the fuzzified solutions with the classical(or crisp) solutions. For this comparison, we estimate the how much the fuzzy solutions diffuse.
