고리원자력발전소 주변의 식생에 대한 식물사회학적 조사를 실시하였으며, 순1차생산력과 식물현존량을 추정하였다. 또한 상관에 의한 현존식생도 및 녹지자연도를 작성하였다. 종조성표에 의한 식물군락은 소나무군락, 곰솔군락, 서어나무-굴참나무군락, 아까시나무군락으로 구분되었다. 소나무군락은 아교목층(평균식피율 35%)이 빈약하였으며, 서어나무-굴참나무군락은 비교적 안정된 계층구조를 이루고 있었다. 전체적으로 교목층에서 소나무, 곰솔, 아교목층에서 사방오리, 졸참나무, 저목층에서 졸참나무, 사스레피나무, 초본층에서 산거울, 주름조개풀 등의 피복지수가 높았다. 삼림토양의 pH는 4.30~4.85, 유기물함량은 6.04~9.40%의 범위였다. 현존식생도에 의한 분포비율은 곰솔군락(31.4%)이 가장 높았으며, 평균녹지자연도는 5.4였다. Montreal model에 의한 순1차생산력은 1555.2g/㎡/yr, 식물현존량은 단위면적당16,982,21ton/k㎡으로 추정되었다. The forest vegetation and estimation of phytomass and net primary production in the vicinity of Kori Atomic Power Plant was analyzed on the basis of the phytosociological data. Depending on physiognomy, actual vegetation map and the degree of green naturality(DGN) was also drawn in the of 1:50,000. According to Z-M method, the forest vegetation was classified into four communities, which include Pinus densiflora, Pinus thunbergii, Carpinus laxiflora-Quercus variabilis, and Robinia pseudo-acacia communities. The Pinus densiflora community was most poorly covered in tree-2 layer. The Carpinus laxiflora-Quercus variabilis community was relatively stable in the stratum structure. It was generally shown that Pinus densiflora and Pinus thunbergii in tree-1 layer, Alnus firma and Quercus serrata in tree-2 layer, Quercus serrata and Eurya japonica in shrub layer, and Carex humilis and Oplismenus undulatifolius in herb layer had high coverage index. The pHs and contents of organic matter of the forest soil collected in each sites was in the range of 4.30 to 4.85 and 6.04% to 9.40% in average in the communities. The Pinus thunbergii community showed the highest distribution rate(31.4%) in the actual vegetation map. The average DGN was approximately 5.4. Net primary production and phytomass per unit area obtained by Montreal model were estimated to be 1555.2g/㎡/yr and 16,982.21ton/k㎡, respectively.

Conflicting results exist on the outcome of off hours PCI in ST elevation myocardial infarction (STEMI). However, there were only a few studies that have focused on the clinical characteristics and outcomes of off hours PCI in STEMI. So, we studied the clinical characteristics and hospital mortality in STEMI patients treated with primary PCI during regular hours (weekdays 9:00 AM to 6:00 PM) versus off hours Weekdays 6:01 PM to 8:59 AM, weekends, and holidays) in Korea Acute Myocardial Infarction Registry. We analyzed in hospital and one year mortality among 5,665 consecutive ST segment elevation myocardial infarction patients treated with primary PCI between November 2005 to January 2008. Total 2,848 (50.2%) patients were treated during off hours. Baseline finding were similar, although regular hours patients were older. Median symptom to balloon time (304 min, IQR 175 to 750 vs. 270 min, IQR 145 to 551, p=0.001) were longer for regular hours primary PCI. Median door to balloon time (71min, IQR: 48 to 132 vs. 59 min, IQR 39 to 110 min, p=0.001) were longer for off hours pPCI. Also, Cardiac enzyme such as Max CK-MB (212.1±299.3 vs 194.7±303.4, p=0.031) and max TnI (72.6±239.5 vs. 58.9±94.4, p=0.013) were increased in off hours pPCI. However, unadjusted in hospital (6.0% off hours vs. 6.0% regular hours, p=0.946) and one year cardiac mortality (11.3% off hours vs. 11.7% regular hours, p=0.661) were comparable. In multivariate analysis, off hours primary PCI did not predict an adverse outcome. In conclusion, when primary PCI was performed within an appropriate reperfusion strategy, the clinical effectiveness of either off hours or regular hours pPCI is comparable.

Background/Aims: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. Methods: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. Results: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). Conclusions: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.

Blackleg disease, caused by Leptosphaeria maculans, greatly aff ects the production of cabbage ( Brassica oleracea ). However,defi nitive R-gene(s) are yet to be identifi ed in this crop. In contrast, a number of R-loci have been identifi ed in A- orB-genome crops. Identifi cation of few resistant cabbage genotypes indicates the presence of R-genes in this C-genome crop. High ancestral synteny between Brassica genomes suggests that the collinear regions of known A- or B-genome R-loci mayalso contain functional R-genes in the C-genome. Strong resistance was observed in the cotyledons of cabbage inbred lineSCNU-98 against two L. maculans isolates, 03–02 s and 00–100 s. We investigated the collinear region of the Brassica napusblackleg resistance locus LepR2’ in B. oleracea since both isolates of L. maculans contain corresponding avirulence genes. The locus was collinear to a 5.8 Mbp genomic segment of B. oleracea chromosome C09 containing 13 genes that have putativedisease resistance-related domains. High expression of genes Bo9g117290 and Bo9g111510 against isolate 00–100 s,and high expression of genes Bo9g126150 and Bo9g111490 against both isolates in the resistant-line SCNU-98 indicatetheir putative roles in blackleg resistance, which remained to be functionally verifi ed. This work enhances our understandingof R-gene-mediated resistance to blackleg in cabbage.

Generally, the number of plant species was scarce, but it was Asparagus cochinchinensis, Dendrobium moniliforme and Bulbophyllum inconspicuum ete. were encountered in the peak of the island (on the Mt. Shinkum). In eastern coast, ever-green broad-leaved forests was mainly consisted of cinnamomun japonicum, machilus thunbergii, Raphiloepis umbellata, Camellia japonica, Eurya emargirata and Ligustrum japonicum. In addition such as Asplenium incisum, Lygodium japonicum, Cytamium fortunei, Melampyrum roseum and Ardisia japonica, Trachelospermum asiaticum var. intermedium, Ardisia crenata were grown as the undergrowth of those forests. Camellia japonica was grown predonimated spontaneously at southwestern coast. By ecological investigation, coefficient of cryptogam of Ha-Jo island is 0.94 and percentage of annual plants is 10.01%.

19세기 서양인의 한국어 문자와 음운 현상에 대한 기술

김인책 부산대학교 인문학연구소 2013 코기토 Vol.- No.73

In the history of Korean linguistics, the nineteenth century showed the inception of the research method of the grammatical description. From the invention of Hunminjeongeum up to the eighteenth century (in which the backdrop for Silhak, realist school of confucianism, was formed), Korean linguistics was characterized by the research on Hunminjeongeum itself. The systematic description of the Korean language first began in the nineteenth century, particularly, by some Westerners. Given the situation, this research aims to provide an analysis and explication with regard to Korean graphemics and phonology, particularly, focusing on the theoretical description available in the Korean linguistic literature in the early and mid-nineteenth century. As most of the post-promulgation studies on the Korean language were concerned with Hunminjeongeum, this paper centers around the questions of (a) how the previous academic insight into Hunminjeongeum’s script and pronunciation systems was reflected and handed down in the academic works by the Westerners in the nineteenth century and (b) how the system of Hangeul and its respective phonetic values were interpreted by those Westerners from their perspective. In the respect of Korean graphemics, the main attention is paid to the sequential order of the consonant and vowel letters in Hangeul as well as to the phonetic values of the respective letters. The sequential arrangement of the letters refers to that of Se-Jin Choi in Hunmongjahoe (1527). One noteworthy finding is that some single identical letter was observed to have two different pronunciations, which was, then, a linguistically fruitful discovery confirming the existence of the allophone in Korean. On the other hand, what drew attention in terms of the pronunciation is that the phonological phenomenon of euphony was highlighted and specified. In the linguistic description, phonologically distinctive phenomena―such as voicing, consonant assimilation, palatalization, initial liquid avoidance, and the final consonant rule―were taken into account and well elaborated in order to increase the general understanding of the Korean pronunciation. For the nineteenth-century Westerners, it was possible to spot those particular phenomena in Korean owing to the fact that they, as speakers of European languages, had the background knowledge of historical comparative linguistics, the main methodological trend of those times. 19세기는 한국어 문법 연구의 태동기이다. 훈민정음 창제 이후 실학 학풍이 배경이 되었던 18세기까지는 훈민정음에 대한 연구가 주종을 이루었다. 한국어 전반에 대한 체계적인 기술은 19세기에 들어서 서양인에 의해 비로소 시작되었다. 본 연구는 19세기 초․중엽 한국어 연구서에 기술된 한국어 문자와 음운 현상에 대해 분석․해설하는 데 목적이 있다. 15세기 훈민정음 창제 이후 한국어에 대한 연구는 대부분이 훈민정음과 관련이 있다. 훈민정음과 발음에 대한 연구가 19세기 서양인의 연구서에 어떻게 반영되고 계승되었는가를 확인하는 것과 서양인의 관점으로 한국어 문자와 그 음가를 어떻게 해석하였는가를 고찰하는 것이 이 연구의 중심 내용이다. 문자와 관련된 것은 자모의 배열 순서와 음가에 대한 것이다. 문자 배열은 최세진의 배열 방법에 준하였다. 동일한 글자에 두 가지 발음이 존재하는 것을 밝혀내었다. 이는 한국어에 변이음이 존재한다는 사실을 확인한 언어학적 수확이다. 발음과 관련된 것은 활음조 현상을 관찰하여 세세하게 기술하였다는 것이다. 유성음화, 자음동화, 구개음화, 두음법칙, 말음규칙 등과 같은 음운 현상을 관찰․기술하여 한국어 발음을 쉽게 이해할 수 있도록 하였다. 19세기 서양인이 한국어에서 이러한 현상들을 발견할 수 있었던 것은 그들이 서양어 화자라는 것과 당시 역사비교언어학이라는 서양 언어학의 경향이 배경이 되었기 때문이다.

A study was made to examine the electrical, compositional, structural and morphological properties of Ag thin films deposited by DC magnetron sputtering in $O_2$ atmosphere with deposition temperature from room temperature to 15$0^{\circ}C$ using in-line sputter system. The Ag films deposited at temperature above $100^{\circ}C$ in oxygen atmosphere gave a similar specific resistivity to and even lower oxygen content than those deposited using pure Ar sputter gas The Ag films deposited with pure Ar gas was mainly composed of crystallites with [111] preferred orientation, while, for those deposited in oxygen atmosphere, more than 50% of the volume was composed of crystallites with [100] orientation. The difference in the micro structure did not cause any difference in the specific resistivity of Ag films. The results showed that the transparent conducting oxide films and the Ag films could be processed sequentially in the same deposition chamber with careful control of deposition temperature, which might result in a cost reduction for constructing the large scale in-line deposition system.

정상과 갑상선 종양조직에서 사람 IGF-I 유전자의 발현

Many of the growth-promoting properties of growth hormone(GH) are mediated by insulin-like growth factor-I(IGF-I), a highly conserved circulating 70-amino acid peptide. Recent studies have shown that multiple mechanisms influence IGF-I gene expression, including transcription from two promoters, alternative RNA splicing, and variable polyadenylation. In thyroid tissue, thyroid stimulating hormone(TSH) and IGF-I are the most possible candidates for follicular cell proliferation and hypertrophy. Actually IGF-I had autocrine and paracrine effect for tissue growing. We prepared thyroid tumor tissue mRNAs using single step method for detecting IGF-I levels according to different tissues, i.e., thyroid adenoma or papillary thyroid carcinoma. We used Northern blot analysis for IGF-I mRNA and RNase protection assay (RPA) for IGF-I transcription start sites. For Northern blot, we used whole human IGF-I cDNA as a DNA probe and for RPA, we used IGF-I exon 1 containing noncoding promoter 1 as a riboprobe. We got good RNA bands from Northern blot analysis around 1 kb (IGF-IA) and 7.5 kb (IGF-IB) region. To clarify the amount of both IGF-IA and IB mRNAs, we measured autoradiographied signal of IGF-I mRNAs bands using densitometer. In IGF-IA signals, there's no change among liver and thyroid tissues, but in case of IGF-IB mRNA bands, the signal was markedly increased in thyroid carcinoma tissues than that of normal thyroid tissue (85% vs 14%). In the study of RPA, all thyroid tissues used the same transcription start sites as those of liver's. We concluded that that this different regulation of IGF-I mRNA was originated from tissue specificity. That meant some tissue specific transcription factor/s were related to tissue IGF-I expression.

적산 소나무림에서의 nitrification에 관한 연구

김종희,김인택 경남대학교 환경문제연구소 1993 환경연구 Vol.15 No.-

경남 고성군에 위치한 적상의 소나무림에서 1992년 10월부터 1993년 9월까지 nitrification을 조사하였다. 각 지소당 낙엽층, 부식질층 및 무기질층으로 나누어 ammonoum oxidation과 nitrite oxidation과정이 조사되었다. Ammonoum oxidation과 nitrite oxidation 모두 부식질층에서 가장 높았고, 무기질층에서 가장 낮게 나타났다. 또한 두 과정에 대한 월별 변이 역시 부식질층에서 가장 컸고, 무기질층에서는 연중 일정하게 나타났다. 이것은 부식질층에 함유된 여러가지 유기물들을 이용하는 토양의 nitrifier들의 활발한 활동의 영향으로 판단된다. 또한 ammonoum oxidation과 nitrite oxidation간의 유의차는 없었다. The ammonium oxidation and nitrite oxidation of pine forest were investigated in Geuk Mountain from Oct. of 1992 to Sep. of 1993. The three soil layers(litter, fermentation, and mineral layers) were taken from each site, and then packed in plastic bags for transport to the 1aboratory. To determine the nitrification process were performed aerobic soil incubation during 26 hours at 20℃ temperature. The concentration of nitrite and nitrate were analyzed by sphectrophotometer after 2, 8, 14, 20, and 26h of incubation. The highest rates of both of the ammonium oxidation and nitrite oxidation were observed in fermentation layer. And also the highest seasonal variation was found in fermentation layer, but the seasonal variation of nitrification had no found in minera1, the rates were relatively constant. These results indicated that the population densities and the activity of nitrifiers are correlated with available nutrients from plant remains in fermentation layers. And there are no significant in the rates of ammonium and nitrite oxidation.
