        洪思滿 慶北大學校 東洋文化硏究所 1979 東洋文化硏究 Vol.6 No.-

        In this approach, the contextual circumstances in sentence were deeply considered. Especially, the semantic relations (i.e. presupposition, implication and assertion) derived by the delimiter 「-man」 were examined. In this paper, I attempt to present semantic functions and interpretations of the delimiter 「-man」 as a whole in Korean living language.

      • 中크롬과 高크롬 페라이트系 耐熱鋼의 機械的 性質

        곽사호 조선대학교 동력자원연구소 1986 動力資源硏究所誌 Vol.8 No.2

        This study aims to contribute to the inprovement of ex-reactor components for nuclear generation, such as steam generators, superheater, tubing materials, turbine blades, etc.. And in this paper the duplex structure and mechanical properties, especially tensile strength, creep-rupture strength, hardness in the weld HAZ, weld cracking characteristics, etc. of middle Cr and high Cr ferritic heat resisting steels were investigated. Creep-rupture test was carried out in the air by the lever type single specimen equipment. Specimens for metallographic examination were etched with Vilella's reagent. The results obtained are summarized as follows : 1. The duplex structures of middle chromium and high chromium ferritic heat resisting steels exhibit beneficial mechanical properties, weldability and creep-rupture strength. 2. 12Cr-2Mo-V duplex steels are so good in weldability, elongation, elevated temperature formability and creep-rupture strength that they are anticipated to be suitable for boiler tubes, superheater, reheater, FBR steam generator, etc. in a nuclear power plant. 3. 12Cr-2Mo steels show better weldability and creep-rupture strength than full-martensitic 12Cr-1Mo steels. But the former exhibits lower tensile strength than the latter. 4. 0.09C-7Cr-3Mo steel gives better mechanical properties than 0.06C-7Cr-3Mo steel except for weldability.

        중세ㆍ근대국어 어휘의미 연구(9) : 의존명사 {다[ㄷ.]}와 {줄}의 의미 분석 Semantic Analysis of bound noun {다[ㄷ.]} and (줄)

        홍사만 한국문학언어학회 2003 어문론총 Vol.38 No.-

        This paper is about the distribution and meaning of Middle and Modern Korean bound noun {ㄷ.}, and their synonymy relation with {줄}. In Middle and Modern Korean, there were various declensional forms of {ㄷ.} such as {ㄷ.ㄹ}(accuastive), {디}(subjective), {ㄷ.ㅣ}(locative), {ㄷ.로}(instrumentative), and {ㄷ.ㄴ}(topic). But among them {디} and {ㄷ.ㅣ} had already been derived forms which were transformed into different bound nouns. Although verbs of recognition, verbs of thinking, verbs of statement, and verbs of sense could be used as the following verbs in the mother sentence when the embedded sentences of {ㄷ.} were worked as the object of the mother sentence, the most common case was to use verbs of recognition. This phenomenon later causes {줄}, lexically changed word of {ㄷ.}, to co-occur only with verbs of recognition. The meaning that Middle Korean is induced in syntactic and semantic circumstance is the "fact"(or truth). It is the semantical function that makes the proposition of embedded sentence as a fact. The semantic similarity between {ㄷ.} and {줄} is very clear when they co-occur with the verbs of recognition(알다/모ㄹ.다(know/do not know)) of the mother sentence. Historically, 「줄 알다(모ㄹ.다)」 is preceded by 「ㄷ.ㄹ 알다(모ㄹ.다)」. When {줄} appeared, it went through the synonymy clash and {ㄷ.} was degenerated. Since then there wasn't any appearnce of {ㄷ.} in the data of Middle Korean. {ㄷ.}'s extinction was caused by its unstability as bound noun. Eventually {ㄷ.} disappeared leaving some traces of its grammatical conjugation endings.

      • 韓國産人工輕量骨材의 特性에 관한 硏究

        洪思天 東亞大學校 1976 東亞論叢 Vol.13 No.1

        1. Backround The rapid advance of science and technology, together with social and economic development, causes the buildings to become mammoth type on a larger scale. Decreasing trend in the production of natural aggregates for the buildings precipitated the development of prefabricated elements, which strongly suggests the needs to reduce the weight of buildings. It is to this need that efforts are being made worldwide to develop artificial light-weight Aggregate for concrete. Recently, the artificial light-weight aggregates, which are still in the process of experimentations in Europe and the U.S.A, have received growing recognition for their potential strength as materials for the buildings. The major advantages of these materials are that they have little water obsorption and provide for an easy control of quality. Furthermore, it is as easy to obtain from them compressive strength up to 200~500㎏/㎠ as in the case of natural aggregates. In Korea, only few studies have been conducted in the past of artificial light-weight aggreates: in 1962, the National Industry Research Institute conducted a study on red clay in four selected are as within country to validate its fitness as a materials for the fired aggregate, and, in 1972, Choi, Sang Hol et al conducted a study for the development of light-weight aggregate using the clay in Song Do. But these studies were limited only to red clay or mud, and no study has been made of shale. As there is an increasing demand for artificial light-weight aggregate in Korea, the need has become acute to conduct comprehensive studies addressed to production method and mixing techniques of them. 2. The Purposes and Scope of this Study The purposes of this study are to analyze the physical and chemical properties of mud and shale, to validate their fitness for a fired concrete aggregate and to identify the usefulness of concrete made of shale in Taegu District, which was found to have a good expansion. Under the foregoing purposes, the scope of this study is defined by the following specific activities: (1) To confirm the expansion theory of mud and shale by analysis of chemical component, measuring pH value and fire resistance of mud and shale. (2) To identify the effects of changes in firing conditions on the expansion of the aggregate materials and to develop manufacturing techniques. (3) To identify the changes of expansion, when a bloater is added on the materials. (4) To conduct thermal analysis to define the corelationship between heating time and heat gravity and do X-ray diffraction pattern to identify the mineral components of each materials and a model of optimum mixture. 3. Conclusion The findings of an analytical study on the properties of the raw materials avaible in korea for artificial light weight aggregate are summarized as follows. (1) The raw materials available in korea for artificial light-weight aggregate fall within the Bloating Zone in SiO₂-Al₂O₃-Flux System by C.M. Riley and expand when the value of pH exceeds five. (2) The mud accumulated along korean seashore is generally bloated by firing, but the mud in the river and inland clay, which are rich in acity, have little or no expansion at all. (3) Since the major component of mud and shale is Quartz the light-weight aggregate made of these materials have high heat resistance and compressive strength. (4) The artificial light-weight aggregate made of mud in yul-Do shows the highest value after heated for 10~15 minutes at the temperature of 1,200~1,250℃. (5) When bloater, CaCO₃, is added to the mud and red clay rich in acidity in the ratio of 3%, the value of pH five rises by 20%, and accordingly expansion increases by the same ratio. (6) The shale in Taegu District shows the highest value after heated for 5~15 minutes at the temperature of 1,150~1,200℃. (7) Pelletized type of aggregate needs to be made at high firing temperature (above 1,250℃) and non-pelletized type of aggregate at low firing temperature (below 1,150℃).

      • 國語 Postposition의 下位 分類 : 相異的 特性 中心으로 according to their differantial characteristics

        洪思滿 慶北大學校 東洋文化硏究所 1976 東洋文化硏究 Vol.3 No.-

        Korean Postpositions are different from Korean case-markers in their semantic functions. In this paper I study the differential characteristics in Korean postpositions by means of the semantical, morphological approach, and try to draw a correct line between the category of postpositions and case-markers. Korean postpositions can be divided into two counterparts both in semantical and morphological aspects. In semantical aspect 1. Domination of predicate: "DISTINCTION" and "IDENTITY" 2. Selectional feature to the mean contents of the following predicate: co-occurance with <+affirmative> and <-affirmative> 3. Meaning shift: "SIMPLE" and "MULTIPLE" In morphological aspect 1. Function of compounding: "PRE-JUNCTION" and "POST-JUNCTION" 2. Function of case-marker deletion: "OBLIGATORY" and "OPTIONAL" 3. Function of addition to adverb: "COMBINABLE" and "UNCOMBINABLE"

      • 國語 程度副詞와 狀態副詞의 比較 硏究

        洪思滿 慶北大學校 東洋文化硏究所 1977 東洋文化硏究 Vol.4 No.-

        In semantic aspect, Korean adverbials are classified as (1) stative (2) degree (3) numeral (4) direction (5) location (6) time (7) shape etc.. Among them, this paper deals with STATIVE and DEGREE adverbs that from the opposite functions each other. In co-occurrence relation with verbals, stative adverbs dominate the <+action> verbal but degree adverbs do the <+stative>. Consequently, the function toward vervals of these two adverbs are as follows: ① degree adverb+<+stative> verbal→intensify to STATIVE ② stative adverb+<+action> verbal→'STATIVIZE' to action ③ degree adverb+stative adverb+<+action> verbal→intensify to'STATIVIZATION' Going one step further, these two adverbs seem to appear as the different shapes in the deep structure. Degree adverbs would appear as ADVERB itself but stative adverbs a <+STATIVE> VERBAL. The latter would have undergone the adverb transformation in the deep structure because of their the feature <+ADVERB>. But this idea requires some more approaches.
