이찬규,이종원 대한기계학회 1990 대한기계학회논문집 Vol.14 No.1

본 연구에서는 제 1보에서 다루었던 프로세스 해석의 결과들을 토대로 하여 열교환기의 최적 설계를 행하는데 주력하였다. 먼저, 열교환기의 최적 설계를 행하 는데 주력하였다. 먼저, 열교환기의 열설계에 필요한 CO$_{2}$와 Natrium의 물성치 및 열전달에 관한 기존의 실험식들을 여러문헌으로부터 연구 검토한 후 프로그램에 편 리하게 이용할 수 있도록 전산화 하였으며, 열교환기의 설계시 필요한 전체 경비의 최 소화를 기하는 방향으로 최적화된 설계인자들을 결정하도록 시도하였고 또한 최적화된 프로그램을 개발함으로써 인력, 외화 및 에너지 절감의 효과를 얻고자 하였다. Optimal design of heat exchanger for closed CO$_{2}$ gas turbine plant of three processes selected from the result of cycle analysis have been discussed previously paper(I) has been carried out under specified inlet and outlet conditions. Independent variables such as number of parallel connection, tube diameter, shell side and tube side pressure loss as well as dependent variables such as shell diameter, number of tubes, number of serial connections were all characterized according to the standardization or so. Search method was used to construct a computer simulation together with the calculation of heat transfer rate by logarithmic mean temperature difference method. Strength analysis of major parts was carried to examine their dimensions satisfying heat transfer and pressure loss requirements.

고 흡수성 폴리머를 혼입한 콘크리트의 기초 물성 및 염화물 침투 저항성 평가

Superabsorbent Polymer (SAP) expands inside concrete by absorbing water and contracts as it discharges water. Through this process, concrete can achieve the internal curing effect, but the space occupied by the expanded SAP remains as a void. In this study, the effects of SAP internal curing and voids were evaluated by evaluating the fundamental properties and chloride penetration resistance of SAP mixed concrete. Also, to evaluate the internal curing effect by SAP, the tests were carried out under water and sealed curing conditions, respectively. From the result, the compressive strength of water curing did not differ significantly according to the mixing ratio of SAP. In the case of sealed curing, however, the compressive strength tended to increase as the mixing ratio of SAP increased. The internal curing effect of sealed curing was considered to have influenced the increase in compressive strength. In the case of the chloride diffusion coefficient, the diffusion coefficient tended to decrease as the mixing ratio of SAP increased. In particular, as the sealed curing is applied, the chloride penetration resistance is further improved due to internal curing effect. If the curing conditions are different, it is considered inappropriate to estimate the chloride penetration resistance by the surface electrical resistivity. 고 흡수성 폴리머(SAP)는 콘크리트 내부에서 물을 흡수하여 팽창하며 물을 방출하면서 수축한다. 이 과정을 통해 콘크리트는 내부 양생 효과를 얻을 수 있지만 팽창한 SAP가 차지하고 있던 공간은 공극으로 존재하게 된다. 따라서 본 연구에서는 SAP를 혼입한 콘크리트의 기초 물성 및 염화물 침투 저항성을 평가하여 SAP의 내부 양생과 공극에 의한 영향을 평가하였다. 또한 SAP에 의한 내부 양생 효과를 평가하기 위해 양생 조건을 수중 양생과 봉함 양생으로 구분하여 실시하였다. 실험 결과, 수중 양생의 압축강도는 혼입율에 따라 큰 차이가 없었으며, 봉함 양생의 경우에는 SAP의 혼입율이 증가함에 따라 압축 강도가 증가하는 경향을 나타냈다. 봉함 양생의 경우 내부 양생 효과가 압축 강도 증가에 영향을 준 것으로 판단된다. 염화물 확산계수 측정 결과, SAP의 혼입율 증가에 따라 확산계수가 감소하는 경향을 나타냈으며, 특히 봉함 양생은 내부 양생 효과로 인해 수화 반응이 촉진되어 염화물 침투 저항성이 더욱 개선된 것으로 판단된다. 양생 조건이 다른 경우 표면 전기저항을 이용해 염화물 침투 저항성을 평가하는 것은 부적절한 것으로 판단된다.

韓國語 二次 敍述 構文의 意味 辨別과 相 構造

이찬규,이성수 한국어문교육연구회 2011 어문연구(語文硏究) Vol.39 No.1

This paper addresses the syntax and semantics of Korean secondary predicate constructions, depictives and resultatives. In doing so we argue that they are separated morphologically, that is, they are marked by different particles, {-a(se)} and {-ke} respectively. They differ in their lexical compositions: {-a(se)} is a contracted form of two syntactic items {-a-} and {-se}, and the former means the duration of a state, a predicate marker and the latter exhibits the time-relation between two events, that is a temporal event sequencer. Whereas {-ke} is merely a predicate marker, a complementiser without a temporal relation. Then depictives are T-projections and relsultatives are non T-projections. So we propose that two different morphemes {-a(se)} and {-ke} reflect the different aspectual structures between Korean dipictives and resultatives, that is atelic vs. telic. We can identify those properties with the test 「-tongan」 vs. 「-mane」 respectively. Korean, however, is not the only language available with morphological differences in two types of constructions. It is relevant in languages like Japanese and Finnish. But such a claim is not readily applicable in languages like English, due to a superficial syntactic similarity between depictives and resultatives. So we propose a language typology abided by morphological distinction:(i) a language typology abided by morphological distinction a. morphologically attested:① attested in verb/adjective secondary predicates: Korean, Finnish ② attested in noun secondary predicates: Japanese b. morphologically not-attested ① but distinct in the position: Chinese ② non-distinct in the position: English, German 이 논문은 韓國語 二次 敍述語 構文의 두 有形인 描寫構文과 結果構文의 자료를 기초로 하여 두 構文이 相的 構造에 있어 차이를 보이는 경험적인 증거를 제시하는 데 목적이 있다. 이를 위해 本稿에서는 한국어 描寫構文과 結果構文이 形態論的으로 구분됨을 주장한다. 描寫構文에 출현하는 형태소 {-아{서)}는 두 개의 요소로 구성되며, 여기서 {-아}는 狀態의 持續을 의미하고, {-서}는 前後의 時間關係를 의미한다. 반면 結果構文에 출현하는 형태소 {-게}는 단일 요소로서 특정 상태에 도달을 의미하는데, 여기에는 시간관계가 포함되어 있지 않다. 이런 時間關係는 T(ense)로의 투사 여부에 따라 描寫構文과 結果構文으로 구분되는데, 描寫構文은 T의 투사이며, 結果構文은 T의 투사이다 결과구문은 투사가 아니다. 따라서 상이한 두 형태소 {-아(서)}와 {-게}의 의미는 描寫構文과 結果構文의 相的特性, 즉 未結atelic)과 完結telic에 반영되고, 이것은 각각 「-동안」과 「-만에」테스트를 통해 확인할 수 있다.

Il est difficile de trouver l’étude précèdente qui s’approche de l’imagination bachelardienne par l’aspect auditif. L’affectivité sonore de Bachelard est d’comprise en vertu du concept de “l’audition projetante”. Elle n’est pas seulement l’ouïe subtile mais aussi signifie l’imagination sonore qui s’offre comme le rétablissement d’“un au-delà du toujours vu”. Contre la civilisation moderne, l’imagination sonore de Bachelard transforme le bruit de la ville en son océanique. Selon son expression, c’est “la naturalisation des bruits”. La résonance sonore constitue donc la communication invisible entre toute les choses, comme le son de la neige est senti dans la flamme d’une chandelle. Dans La flamme d’une chandelle, la particularité de l’image provient de l’idée qui ne considère pas la lumière seulement comme l’objet visuel, mais aussi l’horizon non-visuel. La flamme d’une chandelle est, chez Bachelard, déployée le plus souvent par l’autre système de la sensation corporelle, la capacité auditive nommée la ‘clairaudience’. C’est pourquoi la lumière de Bachelard arrive à “la vie qui parle” et encourage aussi la solitude d’une seule personne. La sensation auditive repose enfin sur la sensation du silence. Le silence bachelardien est loin de l’idée de la mort que la civilisation moderne lui impose. Par contre, le silence devient l’événement de la communication entre “les voix qui s’approchent et les voix qui s’éloignent”. Le silence est pour Bachelard un monde tendu vers un devenir. C’est pourquoi son “audition projetante” est aussi l’expérience auditive qui est apte à saisir “les voix tacites” ou le silence.

Optimum heat treatment producing P.C. wire is the most important for the further drawing. Drawability depends on the metallic microstructure and mechanical properties. Mechanical properties depend on the amount of pro-eutctoid ferrite and the fineness of pearlite. The amount of ferrite and the fineness of pearlite are dominated by the solid solution treatment and the cooling velocity from the sutenitizing temperature to the patenting temperature. Basides the above, the tension stress is very effective for ausenitizing and eutectoid reaction. The results obtained from this investigation could be summarized as follows. 1. Drawabdity was lowered by the precipitation of pro-eutectoid ferrite as the solid solution treating time was longer. 2. Slow cooling velocity from solid solution treating temperature to the isothermal transformation temperature made the drawability poor. 3. Solid solution treatment under tension stress was very effective for reducing the solid solution treating time and for refining the pearlite. 4. Solid solution treatment under tension stress and rapid cooling from 950 % to 540 % made the pearlite fine and increased drawability.

The aim of this study is to make comparison the category of doublespeak and to compare the perception of doublespeak between Korean and American. With the aim of comparing the perception of doublespeak between Korean and American, this study used a questionnaire survey, which was conducted targeting a Korean and American twice. The first survey was on awareness of doublespeak, and the second one on perception of doublespeak. The first is preliminary survey for the second survey. The perception aspects of Korean’ & American’ doublespeak confirmed through the second survey result are as follows. First, Both the Korean and American were found to be influenced much by the interpretation of a person around them in case they didn't accurately grasp the meaning of doublespeak. Second, However in case of a Korean, he/she tended to be influenced much by a person around him/her in case he/she accepted its meaning negatively though he/she knew the meaning of a word clearly. Third, In case of accepting the meaning of doublespeak negatively, the Korean was influenced much by a person around him/her while the American had a high tendency to think that the interpretation of a person around him/her distorted the intention of the first speaker. Fourth, Media had an influence on the interpretation of Korean’ & American’ doublespeak. Fifth, In case both people perceived the doublespeak positively, both the Korean and American were more influenced by the interpretation exposed through the press than a person around them. Last, In case both perceived the double utterance negatively, the Korean and American were more influenced by the interpretation of a person around them than the interpretation exposed through the press.
