An insect faunal survey was carried out to investigate insect community structure along the vegetation community to monitor insect species in forest ecosystem. We performed day and night collections from June to August along three vegetation communities of Is. Nam-hae in 2014: the first stand with Pinus thunbergii, the second P. thunbergii with Quercus serrata and the third P. thunbergii with various Quercus species. In total 2,259 individuals of 532 species, 99 families, 13 orders are identified. Cluster Analyses (CA) showed that all three vegetation communities were relatively similar between vegetation community types. According to indicator species analysis (ISA) result, nine significant indicator species were identified (p < 0.05); five species were found to be affected by the vegetation cluster and four species the month cluster.

Active Dictionary of Russian(=ADR) is an new type of dictionary which aims at combining the latest achievements of linguistic theory with a practical usefulness for a wide range of language learners. ADR is an attempt at its radical modernization in adherence to modern lexicographic principles. In other words, integral description of language and systematic treatment of kindred linguistic phenomena, with the latest theoretical achievements in semantics, syntax, coᐨoccurrence properties and lexicalized prosody. We look forward to showing some lexicographic mechanisms in ADR against other dictionaries. A completely different way to systemize the meaning of words would be alternatives for all of us – grammarians, lexicographers, and laymen alike.

The Computer Algebra Systems in Mathematics Education : A Review of Recent Research

Kwon, Oh-Nam,Shin, Eun-Ju,Shon, Bo-Kyung 이화여자대학교 교과교육연구소 2001 East west education Vol.18 No.-

This study examines the potential role for Computer Algebra Systems(CAS) in such an educational context, particularly their potential to get students more engaged in the learning of mathematics as well as to reduce the "strangle hold" of prerequisite algebraic skills, in courses such as functions, introductory calculus. What is the present status of and near-future outlook for computer algebra in Korean secondary schools? The answer that arises from this review of available fact is: bright with promise, but still dim. Several recent developments have set the stage for an acceleration in the dissemination rate for CAS to high schools. However, this review of some past and present conditions indicates that many years will pass before computer algebra is impacting high school mathematics as much as hand-held calculators are doing now.

金鍾煥,崔信錫,辛昌男 충남대학교 자연과학연구소 1982 忠南科學硏究誌 Vol.9 No.2

Lymnaeidae snails were collected from the 50 spots out of 63 stations where the basins of Geum River. Youngsan River, the lowest part of Nagdong River and Nam River. The snails were identified four species including Lymnaea auricularia. L. ovata, L. pervia and L. trucatula on the bases of the morphological and cytological observations. L. auricularia was found at 31 stations and the most widely distributed species, and L. pervia was found at 27 stations, however another two species were distributed limited spots in the basin of Geum River. The chromosomes of 4 species of Lymnaea snails were observed in the spermatogenesis and Oo^∞genusis. L. auricularia and L.ovata have the haploid chromosome number 17, and L. pervia has the haploid number 16, but L. truncatula has 18.

English Compound Nouns 의 구조

申南澈 建國大學校 人文科學硏究所 1977 인문과학논총 Vol.10 No.-

The purpose of this paper is to analyse the structures of compound nouns in English. The capacity of forming compounds is one of the characteristics of English. A compound is a unit made up of two or more bases, each of which may be used as a separate word and felt to be single terms. In the course of the analysis, we refer to the boundary between a compound and a syntactic structure. Relevant criteria, necessary to determine the boundary, can be drawn from every level: from phonology, semantics, morphology, and syntax. The distinction between a compound and a syntactic construction cannot be consistently asserted in English compound nouns. The difference of / /and / /or / / cannot be always maintained as that of compound nouns and syntactic constructions. These stress patte군 cannot be only partly admitted in both compounds and phrases, but also wholly applicable to many compound nouns. Bloomfield argues that the stress is the best criterion, while some scholars maintain other criteria. Where a morphological criterion is available, sometimes it may be decisive. Semantic criterion has often been emphasized in some compounds. In some cases it is sometimes available to indicate the structural relations of the compounding members by syntactic paraphrases. The phrase (a) black board has a meaning predictable from the individual words and its construction : it refers to any board which is black. But the compound (a) blackboard has a meaning which is not predictable : it is a name for a particular board. Moreover, (a) blackbird is at least a sort of birds, but (a) ladybird is not (a) bird. Nor is (a) blackcap a particular type of caps. Semantic criteria are not sufficient on their own. The arrangement of members in the compound can be emphasized. The hyphens play an important role. The compound nouns show various characteristics according to their own structures. Therefore, to define and analyse the structures in most troublesome. When any criterion is obviously irrelevant, other criteria must be emphasized as a substitute. There is not a formal criterion that can be emphasized for a generally structural definition of English compound nouns. Since compound nouns cover a wide range of different structural relations between their members, it is not easy to classify them by one criterion. But they can be classified on their own structural points of view as follows : 1) position of determinant and determinatum, 2) endocentric construction or exocentric construction, 3) syntactic construction or asyntactic construction, 4) orthographic differences, 5) syntactic paraphrases, 6) parts of speech, and 7) stress pattern.

Ye의 thou代替에 관한 사회언어학적 고찰

신남철 한국강원영어영문학회 1989 영어영문학 Vol.- No.8

The question why Middle English thou was substituted by you in Modern English has not been convincingly clarified. Yet, it is said that there are evidences for 'reverential - ye" in Middle English. This study intends to show how the mysterious disappearance of thou can be better explained in sociolinguistic perspective. Middle English, spoken by the lower class people, was in a state of continuous flux by being mixed with neighboring languages, while Norman French was the language of the nobility. "Reverential - ye" is supposed to have been borrowed from Norman French usage, but there are counter - evidences against its regular usage even in Chaucer's Canterbury Tales, and in Everyman, a century later. Some parts of Marlow's and some others' texts also suggest a suspicion that the 'solidarity - thou" argument is rather shallow rooted These facts converge on nothing less than that the thou- ye difference was probably a dramatic device irregularly adopted by some artists. Since Middle English could not be free of Norman French influence, including the du-vous differentiation of the latter, it can be said that the common people in the medieval Anglo-Saxon society must have been unsusceptible to such honorific device, though advocated by some. The condition that produced this indifference may reasonably have come from multiple social conventions and thoughts that were prevalent in that era. The relevant factors can be concluded to have been unconsciousness of or distance between social classes, preacher - congregation relation, nationalism and egalitarianism. Together with linguistic (phonological) confusion, the medieval religious life seems to have played the primary role. Thus sociolinguistics can help solve linguistic enigmas.

This study was conducted to investigate the effect of O₃ treatment on daily gain, feed efficiency, mortality and economic analysis in growing pigs. A total of 120 crossed pigs [(Landrace x Large White) x Duroc)] initially averaging 9.65 ±0.15kg body weight were used in this experiment for 58 days. The two treatment were non- O₃(Control treatment) and O₃ treatment, Each treatment had four replicates with fifteen pigs per replicated. There were no significant differences in ADG, although O₃ treatments(0.67kg) tended to have higher ADG than control treatment(0.63kg). A feed efficiency was not affected by the treatments. The mortality rate and disease rate and were lower in the treatment than in the non- O₃ treatment, but each treatment was no significant difference(P< 0.05). The income was higher in the O₃ treatment than in the non- O₃ treatment. In conclusion, the results of the experiments that O₃ treatment could be a beneficial feeding condition for mowing pigs in environmental aspects.

In this paper, we describe fabrication method and sensing functions of amorphous magnetostrictive wire. (Fe,Co)77Si8B5 chosen as nonstoichometric composition, is melted under high frequency induced furnance and then the melted composition is injection-quenched on water-flow at high speed revolution through the nozzle. As the result amorphous magnetostrictive-wires whose diameters are about 125㎛ are obtained On investigation of characteristics of the amorphous wires, a sharp Matteucci effect occurs even by low external magnetic field. It occurs by large Barkhausen jump due to magnetostriction of the amorphous wire. As the results of experiments, we find that amorphous-wires have sufficient characteristics needed as high sensitive security sensor material.

중세영어 개방음절에서의 모음연장

申南澈 건국대학교 1982 學術誌 Vol.26 No.1

In the course of development from Old English into Middle English, there were a number of sound changes, which has been a matter of linguistic controversy since the nineteenth century. Originally long vowels in closed syllables-that is, followed by consonant sequences, including lengthened consonants-were shortened, except when followed by those consonantal sequences which caused lengthening. Conversely, originally short vowels and short diphthongs must have been lengthened before certain consonant combinations, especially before a liquid or a nasal + a homorganic voiced consonant, that is, before ld, rd, nd, mb, ng, rl, rn, and r??. But the lengthening did not take place when the consonant combination was immediately followed by another consonant. In the course of the first half of the 13th century and already in the 12th in Northern English, it seems there intervened in English an entirely new principle: the quantity of the vowel depends on the nature of the syllable, whether it is open (i.e. terminated by a vowel) or closed (i.e. terminated by a consonant), and also on the accent and on the length of the word. That is, OE short stressed vowels in open syllables lengthened, in such forms as OE sunu 'son' and OE bacan 'bake'. They became, respectively, ME so￣nes (pl.) and ME ba￣ken. Luick engaged in a heated debate whether the rule of Lengthening in Open Syllables applied to high vowels as well as to non-high vowels. ME short vowels, of whatever origin, were lengthened in open syllables of dissyllabic forms. The lengthening of a, e, o to ??, ??, ?? took place in all the dialects, whereas that of i, u to ??, ?? only took place in some of them. As the lengthening of a, e, o took place earlier than that of i, u and with an entirely different result, they have been dealt in different ways. The resell of the lengthening of i, u to ??, ?? through the intermediate stage ??, ?? was entirely different from that of a, e, o to ??, ??, ??. In the latter case there was only a change in quantity, hut in the former case there was a change both in quantity and quality of the vowels. It has been pretty generally that, as stated by Luick, ?? and ?? in open syllables were lengthened, lowered, and made tense, so that ?? in this situation became ??, and ?? became ??. Short, stressed OE vowels in open syllables merged with originally long OE vowels, ?? and ?? falling together under the phonetic value [??], ?? and ?? under [??], ?? and ?? under [??], ?? and ?? under [??]. Anderson argues that the rules of Lengthening in Open Syllables and Trisyllabic Shortening do fall under the Elsewhere Condition of disjunctive ordering. But his argument is subject to revision. In order to explain Lengthening in Open Syllables in Middle English, the following rules are needed and their order is as follows: (1) Lengthening in Open Syllables, (2) Trisyllabic Shortening, (3) Lowering, and (4) Tenseness Adjustment. That is, all rules including Lengthening in Open Syllables and Trisyllabic Shortening must he linearly ordered.

유산균 발효유가 Streptococcus mutans의 생균수 및 biofilm 형성에 미치는 영향

유산균이 위장관과 구강건강에 probiotics로서 긍정적인 영향을 미치고 있음이 보고되고 있다. 이에 시판되는 유산균 발효유 5종과 우유를 선택하여 우식유발 원인균인 S. mutans에 대한 증식억제 및 biofilm 형성에 미치는 영향을 평가하고, 발효유의 산도, 완충능, 산생성능, 칼슘과 인의 함량을 측정하였다. 유산균 발효유에 S. mutans를 주입한 후 생균수를 측정한 결과 모든 발효유의 %가 증가함에 따라 S. mutans 수가 감소했으나 우유에서는 변화가 없었다. 10% 유산균 발효유에 S. mutans를 주입한 후 biofilm 형성 정도를 측정한 결과 액티브 GG, 불가리스는 biofilm 형성이 감소하였고, 이오는 유의한 변화가 없었으며, 투티, 에이스, 우유는 증가하였다(P<0.05). 유산균 발효유 및 우유의 산도를 측정한 결과 이오(3.48±0.01), 투티(3.67±0.02), 에이스(3.71±0.02), 액티브 GG(4.04±0.02), 불가리스(4.19±0.02) 순으로 나타났다. 유산균 발효유의 산생성능을 평가한 결과 불가리스가 가장 높은 산생성능을 보였으며 액티브 GG, 에이스, 투티, 이오, 우유 순으로 산도 하강 경향을 나타냈다. 이상의 결과는 유산균 발효유가 초기산도 및 산생성능 측정 결과 우식유발 가능성이 있음을 나타냈다. 그러나 유산균 발효유 중에서 농후발효유가 우식유발균인 S. mutans를 억제하였고 biofilm 형성을 감소시켜 긍정적인 효과를 가지고 있음을 알 수 있었다. Lactic acid bacteria worked positively on gastrointestinal tract and oral environment. So I selected commercial five fermented milks and milk. and then I evaluated their effect of growth inhibition and biofilm formation of cariogenic bacteria. Streptococcus mutans. And also calculated the acidity. buffering capacity. concentration of Ca and P ion and pH change of those drinks. After adding S. mutans to fermented milks viable cell count of S. mutans in milk was not statistically different but those in all fermented milks were decreased as concentration of fermented milk increased. When I measured the amount of formed biofilm in 10% fermented milks and milk with S. mutans and compared with those without S. mutans. the amount was decreased in Active GG and Bulgaris while being increased in Tootee. Ace and milk(P<0.05). The fermented milk with the lowest pH value was E5(3.48±0.01). and the highest was Bulgaris(4.19±0.02). pH change of the fermented milks and milk with S. mutans was measured. The highest acid producing fermented milk was Bulgaris. and followed by Active GG, Ace, Tootee, E5, Milk. These results indicated that fermented milks had caries activity due to the value of initial acidity and acid producing capacity. But, concentrated fermented milks had the inhibitory effect against S. mutans, and also had high volume of Ca and P ion that protected teeth. So I suggest that they have positive effect on teeth.
