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.

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.

Streptococcus의 유당분해에 대한 자일리톨의 효과

신강호,양규호,최남기,김선미,오종석 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

자일리톨은 탄소 5개가 있는 탄수화물로 치아우식증을 억제할 목적으로 사용되는 자당 대체물이다. 본 논문은 구강 중요 세균인 Streptococcus mutans, Streptococcus oralis, Streptococcus salivarius에서 유당분해에 대한 자일리톨의 작용을 관찰하고자 하였다. 세균에 대한 유당과 자일리톨의 병합효과를 보기 위하여 분광광도계를 이용한 흡광도를 측정하였고 생균수 검사를 실시하였다. Streptococcus mutans 또는 β-galactosidase에 의한 유당분해에 대한 자일리톨 효과를 보기 위하여 thin layer chromatography와 lactose-PTS activity test를 실시하여 다음과 같은 결과를 얻었다. 1. 유당과 자일리톨을 병합 첨가한 배지에 Streptococcus mutans를 배양하면 배양액 흡광도가 배양 8시간에 증가하지 않다가 배양 24시간에 증가하였다. 배양 8시간에서의 생균수도 유당 단독보다 유당과 자일리톨 병합 첨가 시 적게 나타났다. 2. 유당과 자일리톨을 병합 첨가한 배지에 Streptococcus oralis, Streptococcus salivarius를 배양하면 배양액 흡광도가 배양 8시간에 증가하지 않다가 배양 24시간에 증가하였다. 3. 배지에 유당 단독으로 첨가할 때보다도 유당과 자일리톨을 병합 첨가한 배지에 Streptococcus mutans를 8시간 배양하면 thin layer chromatography상 남아있는 유당이 많았으나, 배양 24시간에는 모든 유당이 분해되었다. 4. 배지에 유당 단독으로 첨가할 때보다도 유당과 자일리톨을 병합 첨가한 배지에서 Streptococcus mutans의 lactose-PTS 활성도가 낮았다. 5. 배지에 유당 단독으로 첨가할 때보다도 유당과 자일리톨을 병합 첨가한 배지에 β-galactosidase 사용시 thin layer chromatography상 유당이 많았다. 이상의 결과는 자일리톨이 Streptococcus의 유당 이용을 억제함을 시사하였다. Xylitol is a 5-carbons carbohydrate, which can be replaced with sucrose for preventing dental caries. To study the effect of xylitol on the fermentation of lactose in bacteria, the important oral bacteria such as Streptococcus (S.) mutans, S. oralis and S. salivarius were studied. The optical density using spectophotometer and the cell concentration were assessed to evaluate the combined effect of lactose and xylitol against the bacteria. Thin layer chromatography and lactose-PTS activity test were performed to evaluate the effect of xylitol on the fermentation of lactose in S. mutans and by β-galactosidase with the following results. 1. The optical density of Streptococcus mutans culture was not increased for 8 hours-incubation in the media added with lactose and xylitol, but was increased at 24 hours-incubation. The number of viable cells at 8 hours-incubation was smaller in the media containing lactose and xylitol in comparison with lactose only. 2. The optical densities of Streptococcus oralis culture and Streptococcus salivarius culture were not increased for 8 hours-incubation in the media added with lactose and xylitol, but were increased at 24 hours-incubation. 3. When Streptococcus mutans was incubated for 8 hours in the media added with lactose and xylitol. the amount of remained lactose was larger compared with the media added with lactose only. But all lactose was fermented in both media after 24 hours-incubation. 4. When Streptococcus mutans was incubated in the media added with lactose and xylitol, the activity of lactose-PTS was higher compared with the media added with lactose only. 5. When β-galactosidase was incubated in the media added with lactose and xylitol, the amount of remained lactose was larger compared with the media added with lactose only. These results indicated that xylitol inhibited the fermentation of lactose by Streptococcus.

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.

머리부분에 방사선조사를 받은 흰쥐 샘뇌하수체의 변화에 대한 면역전자현미경적 연구

신기호,박경호,안의태,양남길,고정식 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.2

본 실험은 과다한 X-선에 머리부분이 노출되었을 때, 샘뇌하수체의 변화를 알아보기 위하여 시행하였다. 체중 200-250g의 Sprague Dawley계 숫흰쥐를 실험동물로 사용하였으며, 정상군과 방사선조사군으로 나누었다, 방사선조사군은 조사량에 따라 3,000 rad 조사군과 6,000 rad조사군으로 나누어, 방사선 조사후 6시간, 2일 및 6일 후에 도살하여 조직을 절취하였다. 방사선조사는 흰쥐를 sodium thiopental로 마취한 후 방사선선형가속기(Mitsubishi Linear Accelerator ML-4MV)를 사용하여 머리부위를 조사하였다. 조사조건은 조사거리 80 cm, 조사구역 30 cm X 30 cm, 조사깊이 1.2 cm(100% skin dose)였으며, 분당 200 rad씩 조사하였다. 샘뇌하수체는 1% glutaraldehyde- 1% paraformaldehyde액으로 일차 고정한후, 2% osmium tetroxide액에 이차고정하였으며, 고정이 끝난 조직은 alcohol과 acetone으로 탈수한 후 araldite혼합액에 포매하였다. 포매된 조직은 , LKB-V ultratome으로 60-70nm두께의 절편을 작성하여 300 mesh nickel grid에 붙인 다음 젖샘자극호르몬과 성장자극호르몬에 대한 단독면역염색 및 이중면역염색을 시행하였다. 면역염색이 끝난 절편은 uranyl acetate와 lead citrate로 염색한후, JEM 100CX-Ⅱ 전자현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1. 젖샘자극호르몬분비세포는 불규칙한 모양을 한 큰 분비과립(300-700 nm)을 가진 성숙세포, 크기가 다양한 둥근 분비과립(150-200 nm)을 가진 중간 세포와 크기가 작은 둥근 분비과립(100-150 nm)을 가진 미성숙세포로 나눌 수 있었다. 2. 성장자극호르몬분비세포는 크고 둥근 분비과립(200-500 nm)을 가진 제 1 형 세포와 상대적으로 작고 둥근 분비과립 (150-200 nm)을 가진 제 Ⅱ형 세포로 나눌 수 있었다. 3. 방사선 조사후 6 시간군에서 3,000 rad에서는 큰 변화가 없었고, 6,000 rad에서는 사립체와 과립형질내세망의 수조 확장이 관찰되었다. 방사선 조사후 2일군에서는 큰 변화가 없었으며, 6일군에서는 핵막구조의 확장이 관찰되었다. 4. 세포의 종류도 젖샘자극호르몬분비세포는 3,000 rad 조사군과 6,000 rad 조사군 모두 2일군에서는 성숙형이 감소하고 중간형과 미성숙형이 자주 관찰되었으며, 6일군에서는 정상군과 같은 분포양상을 보였으나 분비과립의 금입자표지가 감소한 것을 관찰할 수 있었다. 성장자극호르몬분비세포에서는 뚜렷한 세포형이 분포변화는 관찰할 수 없었으나 금입자표지의 감소는 나타났다. 5. 방사선조사후 6시간군에서 부터 mammosomatography가 나타났는데, 한 세포 내에 젖샘자극호르몬과 성장자극호르몬을 지닌 분비과립이 함께 존재하였으며, 세포의 모양은 다핵세포의 형태를 하고 있는 것과 불규칙한 모양을 한 것이 있었는데, 이와같은 결과는 방사선조사 후 샘뇌하수체의 기능저하에 따른 보상작용으로 나타난 현상이라 생각된다. 이상의 결과로 보아 방사선 조사를 받은 초기에는 분비과립의 방출이 과다하게 일어나며, 방사선 조사의 영향으로 세포질소기관의 기능이 약화되어 6일이 지나면 샘뇌하수체의 호르몬분비능력이 저하되는 것 같다. This experiment was performed to study the morphological changes of the adenohypophysis of rat following X-ray irradiation. Male rats were divided into normal and X-ray irradiation groups. The heads of rat were exposed to 3,000 rads or 6,000 rads of radiation in a single dose. X-ray source was a Mitsubishi Linear Accelerator ML-4MV. Only the heads of animals were exposed at the distance of 80 cm, within the area of 30 X 30 cm, in the depth of 1 cm, with the speed of 200 rad/min. Animals of X-ray irradiation group were sacrificed on 6 hours, 2 days and 6 days after the irradiation. Tissue blocks of adenohypophysis were fixed in the 1% glutaraldehyde - 1% paraformaldehyde solution, followed by refixation in the 2% osmium tetroxide solution. Dehydradted blocks were embedded in araldite mixture. The sections were cut on a LKB V ultrotome, and ultrathin sections were places on bare nickel grid(200 mesh). The section-bearing grids were floated upside down on the solutions in a moisture chamber at room temperature. Sections were single immunostained or double immunostained for prolactin and/or growth hormone. And the sections were jet washed with distilled water. The immunostained sections were contrasted with uranyl acetate and lead citrate, and observed with JEM 100CX II electron microscope. The results were as follows: 1. Three types of the prolactin cells according to their size and shape of secretory granules were found; mature type cells contained large pleomorphic secretory granules(above 500 nm). intermediate type cells contained round granules of varying size(200-250 nm), and immature type cells contained small round granules(100 nm). 2. Two types of the growth hormone cells according to their size of secretory granules were found: type I cells contained large round secretory granules(200-300 nm) and type II cells contained small granules(100-200 nm). 3. Six hours after the irradiation, adenohypophysis showed swollen cisternae of granular endoplasmic reticulum and alterations of mitochondrial cristae, but only in doses of 6.000 rads. 4. Adenohypopysis showed decrease in number of mature type prolactin cells on 2 days after irradiatin, and recovered number of mature typer prolactin cell. but their immunoreactiveity were gradually decreased following the irradiation, as compared with that in normal adenohypophysis. 5. Six hours after the irradiation, mammosomatotrophs were found to contain prolactin and growth hormone within different granules each other. Some cells were multinucleated, and some cells exhibited irregular cytoplasmic processes. Summarizing the above results, adenohypophysis rapidly released the secretory granules after the irradiation, and cell organelles of prolactin cells and growth hormone cells were altered or degenerated. It means that adenohypophysis decreased its hormone producing activity on 6 days after irradiation.
