現代 漢語의 副詞 硏究

李根孝 慶星大學校 1997 論文集 Vol.18 No.1

Adverb in modern Chinese language has used for 70 years in Chinese linguistic world The word 'adverb' was introduced by Li, Jin Xi (黎錦熙) in 1924. The number of adverb in modern Chinese language amounts to more than 600. The function adverb is complicated and diverse, and so adverb plays an important role on Chinese phraseology. Because adverb can not be used individually, it belongs to an expletive and becomes the word of situation. This thesis aims to exaime the charactristics of adverbial diction, mutual relation between adverb and conjuction, adverb and Jie ci (介詞), and the fuction of adverbial diction. This study is confined to modern Chinese language. The subject of investigation is adverb currently used in practical sentences and in modern Chinese dictionary. The total of 628 adverbs were classified according to adverbial nature. The results are as follows : ① Cheng du Fu ci (程度副詞) accounts for 12.10% and accounts to 76 of 628 items. ② Fan wei Fu ci (節圖副詞) accounts for 10.19% and 64. ③ Shi jian Fu ci (時間副詞) accounts for 21.01% 132. Compared with other adverb, Shi jian Fu ci takes a considerable share. ④ Ken ding Fu ci (肯定副詞) accounts for 1.43% and 9. It takes a very rare share. ⑤ Fou ding Fu ci (否定副詞) accounts for 2.70% and 17. It takes a rare share. ⑥ Yu qi Fu ci (語氣副詞) accounts for 19.90% and 125. It takes relatively much share. ⑦ Tui ding Fu ci (推定副詞) accounts for 1.11% and 7. It takes a very rare share. ⑧ Jin zhi Fu ci (禁止副詞) accounts for 0.63% and 4. It seems to be seldom used. ⑨ Chong fu Lian xu Bing lie Fu ci (重複. 運續. 竝列副詞) accounts for 3.02% and 19. ⑩ Fang shi Fu ci (方式副詞) accounts for 26.43% and 166. It takes much share. ⑪ Guan lian Fu ci (關聯副詞) accounts for 1.43% and 9.

Recently, combined with social complexity, increment of medical demand and supply and the change of esthetic category, admission and operation of the patients of facial deformity have been changed with annual change. This study was conducted in the concept of helping the overall character of orthognathic surgery in future understood and being an important index in the establishment of better treatment course, through the patient, on whom was operated orthognathic surgery via sagittal split ramal osteotomy in our Dept. of Oral & Maxillofacial Surgery, Chonbuk National University Hospital from 1991. 1. 1 to 1995. 12. 31. The results were obtained as follows. 1. The ratio of male to female was 1 : 1.33 and the ages between 16 and 25 year was 73.6%, and the mean age was 20.4 years. 2. The ratio of setback amount between 6 to 15mm was 84.6% and the advancement amount between 1 to 10mm was 89% and the mean amount of movement was 9.0mm in setback, and 3.6mm in advancement. 3. After removal of maxillomandibular fixation(MMF), the distinction of sex was not statistically significant in ROM. 4. The ROM following methods of fixation was statistically significant in 3rd(P<0.05), 8th, and 12th week(each P<0.01), with faster rehabilitation in rigid fixation which had shorter MMF period. 5. The rehabilitation of ROM following the operation methods was statistically significant in 1st(P<0.05), 2nd, 3rd, 4th, 6th, 8th, and 12th week(each P<0.01) with faster rehabilitation in the case of SSRO than Lefort I / SSRO (Two jaw surgery). 6. The rehabilitation of ROM following directions of mandibular movement did not manifest a statistically significant difference in both setback and advancement.

In this study, We show that MAC and MDC which are currently used for the message authentication are insecure against several active attacks. MAC is analyzed in two cases, MAC with/without a secrecy of message. The cryptographic strength of MDC is also tested under ciphertext-only attack. Also proposed is a new method which can resolve drawbacks of MAC and MDC. It is advantageous in that the message attack which is attacked can be detected immediately. The proposed method can be applied to implement an efficient and secure message authentication on ATM network system because of its capability of early dectection of the attacked cell.

石油抽出産業의 會計處理에 관한 硏究 : 測定方法과 減耗償却을 中心으로 Centering on Measurements and Depletion

陸根孝 부산외국어대학 1984 논문집 Vol.2 No.-

Nonrenewable resources such as Oil and Minerals are the inevitable center of attention in discussion of depletion and exhaustion. Financial reporting and accounting practices used in the petroleum industry differ both among firms within the industry and also from practices of other industries in several respects. Such areas are accounting for prediscovery costs, determination of the cost center, disposition of capitalized costs and disclosure of supplementary information on financial reports. The objective of the present paper are to ; (1) identify the variations of four basic accounting alternatives and reasons for accepting current value accounting ; (2) compare the market response to the different accounting numbers generated under these alternative accounting procedures ; (3) demonstrate by way of additional research how economic factors may have affected depletion method. And also, this paper include information concerning depletion of proved oil and gas reserve quantities. Like discovery value accounting, current value accounting for oil and gas reserves requires estimation of reserve values. The uncertainties inherent in those estimates tend to make them subjective and relatively unreliable. However, the quantity of some natural resources owned by an enterprise can be measured with sufficient reliability to provide useful information. For example, acceptable measurements can be made of the quantity of proved oil and gas reserves. A degree of objectivity can also be obtained by assuming the continuance of price levels prevailing at the date of the measurement. The result of this study cast doubt the use of cost allocation on historical cost standards in depletion method, so called unit-of-production, of proved oil and gas reserve quantities and suggest the need for market price (current value) standards, because market price include development of techniques and changes of production function and marginal user cost, that is the present value of the marginal rent foregone in the future as a result of increased output today. Appendix 1-5 contain illustrations of certain disclosures about oil and gas producing activities.

Histone 분획 H1의 Subfraction 에 관한 연구

이경효,이희성,이근배 중앙대학교 의과대학 의과학연구소 1975 中央醫大誌 Vol.1 No.1

The very lysine-rich histones(H1) from normal leucoctyes, myelocytic leukemia leucocytes, human and bovine colostrum, and bakers' yeast were prepared according to the method of Johns, and Phillips and Johns. The purity of H1 fractions from various sources was checked by 15% polyacrylamide disc gel electrophoresis. The amino acid composition of each H1 fraction were determined by ion exchange chromatography procedure described by Spackman et al. These very lysine-rich histones were, further, subfractionated by chromatography on Amberlite IRC-50 with a shallow guanidinium chloride gradient. The results obtained were summarized as follows: 1) The yield of H1 fractions from various sources greatly differed each other. For example, in myelocytic leukemia leucocytes the levels of H1 was many times that of H1 in normal colostrum, suggesting that the levels of H1 is dependent on the function of tissue proper. 2) The electrophoretic mobility of individual very lysine-rich histone fractions gave similar patterns to those of corresponding fraction from various sources. 3) The chromatographic profiles of very lysine-rich histones from leucocytes, colostrum and bakers' yeast revealed that there were significant differences in molecular species and relative amounts between various biological species. 4) Amino acid composition of histone H1 examined in the present studies, could be classified into two categories. One of these groups resemble the very lysine-rich histone found in eukaryotic cells, i.e., normal leucocytes, human and bovine colostrum. The other group, which may be confined to the myelocytic leukemia leucocytes and bakers' yeast, exhibited quite lower Lys/Arg ratio which due to lesser contents of arginine residues in the subfraction molecule.

安根孝 大韓法醫學會 1990 대한법의학회지 Vol.14 No.1

It has been accumulated a number of research works on Phytagglutinin(PHA) reported by many investigators. Recently, the utilization of PHA in the medical field is increasing, especially as a lectin for the blood grouping. Therefore, the extracts of ground seeds of Korean Caragana Chamlagu Lam. (CCL) were prepared in the usual manner, thereafter the agglutination test with (RBC) with human sera, whole blood, and washed RBC were carried out. The results were as follows ; 1. CCL were reacted on mouse RBC as Pan-Phytagglutinin. 2. Pan-phytagglutinating activity of CCL on mouse RBC was inhibited by certain human sera, while it was failed to inhibit by others. The distribution of the former was 51% and the latter was 49%, respectively. 3. Pan-phytagglutinating activity of CCL on mouse RBC was inhibited by certain human RBC, while it was failed to inhibit by others. The distribution of the former was 57% and the latter was 43%, respectively. 4. There was no relation to the distribution of CCL-inhibitor in human sera and RBC among ABO blood groups.

독일어 삭제 현상

Ausgehend von der Sonorita¨tshierachie bzw. der konsonantische Stra¨ke der Laute gilt fu¨r die deutschen phonologischen Prozesse, besonders die deutschen phonologischen Tilgungserscheinungen kahnsche Silbentheorie.(Vgl. Kahn, D.1976) Mit Bezug auf kahnsche Silbentheorie und Silbentheorie und Sonorita¨shieraschie kann man phonologische Regeln z.B. u¨ber Vokale "Schwa -/a/ ", konsonantische Tilgungen und Assimilationen aufstellen. Vor allem durch Ausfall des Schwa vor den silbischen Konsonaten(/m.n.l/) ergibt sich Assimilation. Aus diesem Grund finden sich assimilierte sillbische Konsonaten nicht in der Koda, sondern im Nukleus. Zusammenfasssend la¨ßt sich sagen, daß die Doma¨ne fu¨r phonologische Prozesse aller Art die Koda oder Reim ist, wa¨hrend der Onset relativ stabil bleibt.(Vgl. Vater. 1992)

비등 40% MgCl_2 용액에서 22Cr5Ni2Mo 2상 스테인리스강 용접재의 응력부식균열 특성

김효종,이성근 동아대학교 공과대학부설 생산기술연구소 1996 生産技術硏究所硏究論文集 Vol.1 No.2

The microstructure and stress corrosion cracking behaviors in 22Cr5Ni2Mo suplex stainless steel weldment have been investigated. The SCC has been examined in terms of relevant electrochemical parameters in boiling 40% MgCl₂solution. The austenite content of the weld metal had twice as much as that of the base metal due to the effect of additive elements Ni, N and reheat effect by the multipass welding. The steel had the threshold stress of 29.1 kg/㎟ and the critical cracking potencial(E_CC) of -410mV immune to the SCC, and possessed superior SCC resistance compared to the austennitic stainless steel. Above the E_cc the SCC of the weldment occurred at the base metal regardless of the welding method. Cracks were initiated and propagated transgranularly without retarding effect by the phase the austenite phase in high stress region.
