本 調査는 1987年 5월 13일부터 1987年 8月 16日 까지 4次에 걸쳐 舒川火力發電所 隣近地域의 植生을 조사한 것으로 本 地域의 植生을 分析하기 위해 群落構造와 群落斷面圖, 現存植生圖와 綠地自然圖를 작성하였다. 自然植生破壞의 指標가 되는 羊齒植物係數(Pte-Q)와 都市化指數(U.I.)는 각각 0.83과 10.96으로 나타났다. 綠地自然度는 0, 1, 2, 6, 7의 5等級으로 구분되었고 加重値로 계산한 平均綠地自然度는 3.52이었다. 現存植生圖와 群落構造에서 나타난 바와 같이 優占種은 곰솔이었으며 調査地의 植生은 소나무림과 곰솔림 그리고 참나무림의 3群落單位로 區分되었고 침엽수림의 構成種은 21-30種이었으며 신갈나무림은 25種이었다. 한편 침엽수림하에는 상수리나무, 신갈나무 졸참나무, 오리나무等의 闊葉樹幼木이 자리잡고 있기 때문에 人爲的 干涉이 중단되면 闊葉樹林으로의 植生遷移가 일어날 수 있는 地域이다. 한편 群落斷面圖에서 보면 針葉樹林下의 植被率은 喬木層 70-85%, 灌木層 30-35%, 下床 草本層은 15-25%를 나타내었고 신갈나무림의 植被率은 喬木層 80%, 灌木層 30%, 草本層 20%를 나타내었다. The vegetation in the vicinity of the Seochon Power Plant was investigated four times from May 13, 1987 through August 16, 1987. In order to analyze the vegetation of this area, the forest structure, profile diagrams, actual vegetation map and the map of the degree of green naturality were worked out. The coefficient of pteridophytes(Pte-Q) and urbanization index(U.I.) as to the destruction degree of naturel vegetation shows a low value of 0.83 and 10.96 respectively. Five different grades of DGN ; 0,1,2,6 and 7 have been registered and the average DGN is 3.52 for the surveyed area. The dominant species was Pinus thunbergii. The vegetation of this surveyed area consists of three units ; Pinus densiflora forest, Pinus thunbergii forest and Quercus spp. forest. There are 21-30 species in the coniferous forest and 25 species in the Quercus acutissima,forest. It may be considered, however, that if artificial interference were discontinued on coniferous forest, such broad-leaved trees as Quercus acutissima, Quercus serrata, Alnus japonica, Quercus mongolica, which are developed in its lower part, would take place. In the profile diagrams of the coniferous forest, the percentage of vegetation of tree layer is 70-85%, shrub layer 30-35% and herb layer 15-25%. In the forest of Quercus mongolica the percentage of vegetation of tree layer is 80%, shrub layer and herb layer are 30% and 20% respectively.

Current business accounting related rules induding Korea financial accounting standards, commercial law are retaining unique reason for being and own characteristics respectively. Come from by this, There is conflicting from several parts between commercial law and financial accounting standards. Therefore, there are serious confusion and social waste in staff in charge' s position such as companies and competent authorities which must apply this. Purposes of this study to exarnine relation and reason of disharmony between both and involved problem in each rule and to present revision direction and repletion direction of individual accounting related rules, and reasonable and realistic re-thesis alternatives between commercial law and financial accounting standards. This study adopted the methodology of deductive literature research which examine prior research and foreign cases and research contents of related laws. Together, this study aims to new groping in the up- to- date revision tendency after reflected Academic symposium entitled ’Relation lighting among accounting related rules in global world' that Korea Accounting Association, Korea Academic Society of Taxation and Korea Commercial Law Association holds jointly on January, 2005 and amended bill of commercial law which legislation advanced notice in October 2006 via public hearing of July, 2006 on October. Difference between commercial law and financial accounting standards are caused from lacks of the systematic consistency basically. Substantial alternatives to solve these problems may consider as follows: First, Japan style alternative that keeps current commercial law and structure of regulation on external audit of corporations and gropes agreement with financial accounting standards. secondly, alternative that revise the system of calculation regulation in commercial law sharply and delegate business accounting principles in financial accounting standards by commercial law that is not regulation on external audit of corporations. When remodels the system of accounting related rules newly which laying stress on commercial law, There needs to prescribe basic and essential items about business accounting principles to commercial law and to ready detail and technological items which is involved with accounting processing to business accounting standards by private- sector organization. Furthermore, It needs to the legal ground about establishment of private- sector organization to commercial law. And need to erase the legal ground of financial accounting standards of regulation on external audit of corporations and move by commercial law because company account standard doesn’t have logical basis or reason that must be based on external audit of corporations, and there is no justice that financial accounting standards should be applied to company which assets scale is more than seven billion It is difficult to apply to financial accounting standards in small and medium-sized entities which include human company and private merchant, and It equips global convergence in business exactly to general company and small and medium-sized entities in situation that financial accounting standards are globalized and complexed. Therefore, It is necessary to discussion multiple tier of account standard and enactment of medium and small enterprises accounting standards. Hereafter, It must include institutional basic regulation to commercial law in order to enact IFRS, Stratification of GAAP, and separate accounting standards for small and medium-sized entities.

저자들은 건강검진에서 시행한 복부 초음파검사상 우연히 좌측 부신 종괴가 발견되어 복부 전산화 단층 촬영검사와 호르몬검사를 시행한 후 부신피질 악성종양과의 감별 진단을 위해 부신절제술과 전자현미경검사를 포함한 병리조직학적 검사를 시행하여 부신피질호산성 과립세포종으로 진단한 증례를 경험하였기에 문헌고찰과 함께 이를 보고하는 바이다. Oncocytomas are neoplasms, histologically are composed of epithelial cells, with abundant, acidophilic and granular cytoplasm. Electron microscopic studies of oncocytomas have shown that the cytoplasm of oncocytes is packed with mitochondria. The adrenal gland is a very rare anatomical site for oncocytomas, and to the best of our knowledge, only thirty-six cases of adrenal oncocytomas have been described. Herein, a case of a large adrenal mass in a forty-year-old man, which was incidentally detected by abdominal ultrasonography, is presented. This patient demonstrated no clinical manifestation associated with adrenal hyperfunction. Hormonal studies showed no abnormal findings, except for a mild elevation of the 24-hour urinary VMA level. Abdominal computed tomography with enhancement revealed a large, well-defined left adrenal mass, measuring 5.0×4.2 ×3.0 cm. The patient underwent a left adrenalectomy, and a light microscopic examination confirmed an adrenocortical oncocytoma, with characteristic oncocytes and polygonal, abundant, eosinophilic and granular cytoplasm. The tumor cells were positive for cytokeratin and vimentin as well as S-100, but negative for chromogranin on immunohistochemical staining. An electron microscopic examination demonstrated closely packed mitochondria, containing intramitochondrial inclusions. After surgery, there was no evidence of a recurrent or distant metastatic disease at the 5 month follow-up. In summary, an extremely rare case of a man with an adrenocortical oncocytoma is reported, which was confirmed by histological examinations, including electron microscopy (J Kor Soc Endocrinol 19:82∼89, 2004).

This is the research paper on the curriculum improvement of Kyungpook National University. The curriculum of a college or university is the organized contents of all courses in order to accomplish the educational goals of the higher institution in an effective way. Needless to say, when curriculum is developed, the needs of the society and of the nation where the university is located, should be sufficiently reflected on its development. As an effort toward improving educatioal programs of higher institutions, the Ministry of Education has been encouraging each college or university to engage in the "Pilot Schol Project", a national experimental academic refrom project which was started in 1973 under the sponsorship of the Ministry of Education. In compliance with this policy, Kyungpook National Uuiversity has been not only making its every effort in improving the curriculum by each college within the campus since 1973, but also, continuing its research on the curriculum development in various areas. The research team has been attempted to systematize the direction of the curriculum improvement to meet the needs of the present and of the modern soceity by indicating the particelar characteristics of each college curriculum. This research paper has been focused on testing the validity of the contents of the revised curriculum which covers such areas as the minimum credit hours required for graduation, division making, and sequence of each division, etc.. As a research tool for the purpose of this study, comparative method has been utilized in order to verify the validity of the revised curriculum by means of comparing the above listed items with the current our university curriculum and those of the advanced countries.

실온에서 알루미늄 산화층(SiO_2)-반도체〔Si(100)_p형〕 소자의 경계면 반응을 Ar^+이온 sputter총을 부착한 AES로 수행했다. SiO_2-Si 경계면은 Si-Si 결합, Si-O 결합의 두 가지 상태를 갖고 있으며, 경계면 넓이는 약 30Å였다. Al-SiO_2-Si 반도체 소자의 경계면 반응은 SiO_2 속의 자유 실리콘이 알루미늄 표면으로 확산되고, 알루미늄과 SiO_2 경계면에 대량의 자유 실리콘이 존재한다. Al-interfacial layer(SiO_2)-semiconductor Si(100)_p-type structures were investigated by the Auger Electron Spectroscopy. The results of depth profiling Ar^+ -ion sputtering are presented for the SiO_2-Si(100)_p-type cell. In the interface, Silicon exists in only two distinct bonding states: Si-Si or Si-O bonding. The exact width of the interface is known as indefinite, but here we estimate it approximately 30Å. The results of depth profiling Ar^+ -ion sputtering are also presented for the Al-SiO_2-Si(100)_p-type cell. Metal(Si) atoms from deposited interfacial oxide layer were observed on the Al surface. The interfacial reaction takes place between Al and the interfacial layer at the room temperature. The diffusion of metal(Si) atoms from the interfacial layer towards the Al surface is suspected to play a role in degradation effect in the MIS solar cells.

Lee, Su-Hwan,Bae, Hui-Su,Oh, Yang-Yeol,Lee, Sang-Hun,Kim, Yeong-Joo,Kim, Sun,Ryu, Jin-Hee,Jung, Kang-Ho,Lee, Choong-Geun,Kim, Jae-Hyeon,Kim, Yeong-Doo,Choi, Weon-Young,Cho, Jae-Yeong,Lee, Kyoung-Bo,Le 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.6

It is known that the poor soil fertility of newly reclaimed saline soils is due to the lack of organic matter and available mineral nutrients for crop production. The effect of green manuring with Sesbania aculeata in combination with five rates of urea-N treatments (N0. N25, N50, N75, N100) on the productivity of a subsequent whole-crop barley and the fertility of the reclaimed saline soil in Saemangeum was evaluated in the field during 2013-2014 growing season. Sesbania was grown during summer season (June to October). The amount of Sesbania incorporated was $16.2Mg\;ha^{-1}$. Sesbania contributed to $393kg\;N\;ha^{-1}$ to the soils when ploughed down and incorporated before whole-crop barley cultivated. The performances of whole-crop barley following sesbania incorporation were significantly affected by a combination of Sesbania manuring and different N rates. The N fertilizer equivalence without N fertilizer following Sesbania was 42.6% ($63.9kg\;N\;ha^{-1}$), compared with N100 ($150kg\;N\;ha^{-1}$) in fallow soils. The whole-crop barley yield responded to N fertilizer rates in both sesbania-amended and fallow soil. The yield response to nitrogen rates in fallow soil was linear (Y=0.0586X+3.3011, $R^2=0.9534$), whereas that in sesbania-amended soils was quadratic (Y= -0.001X2+0.1322X+5.7143, $R^2=0.9576$). The yield of whole-crop barley in sesbania-amended with increasing N rates was increased up to SN75 (115 kgN) $10.3Mg\;ha^{-1}$. Apparent N recovery (ANR) of whole-crop barely showed decreased with sesbania plus increasing rates of N fertilizer. Despite higher yield with sesbania manuring plus increasing N rates, the contributions of N from Sesbania with increasing N rates to whole-crop barley were decreased, whereas those from fertilizer increment due to excessively mineralized Nitrogen. Considering yield, ANR, N contribution from Sesbania and nitrogen fertilizer, the optimum N rate was N50 rate following sesbania incorporation.

Perspective : Self-renewal and circulating capacities of metastatic hepatocarcinoma cells required for collaboration between TM4SF5 and CD44

( Doo Hyung Lee ),( Jung Weon Lee ) 생화학분자생물학회(구 한국생화학분자생물학회) 2015 BMB Reports Vol.48 No.3

Tumor metastasis involves circulating and tumor-initiating capacities of metastatic cancer cells. Hepatic TM4SF5 promotes EMT for malignant growth and migration. Hepatocellular carcinoma (HCC) biomarkers remain unexplored for metastatic potential throughout metastasis. Here, novel TM4SF5/CD44 interaction- mediated self-renewal and circulating tumor cell (CTC) capacities were mechanistically explored. TM4SF5-dependent sphere growth was correlated with CD133+, CD24-, ALDH activity, and a physical association between CD44 and TM4SF5. The TM4SF5/CD44 interaction activated c-Src/STAT3/ Twist1/ B mi1 signaling for spheroid formation, while disturbing the interaction, expression, or activity of any component in this signaling pathway inhibited spheroid formation. In serial xenografts of less than 5,000 cells/injection, TM4SF5-positive tumors exhibited locally-increased CD44 expression, suggesting tumor cell differentiation. TM4SF5-positive cells were identified circulating in blood 4 to 6 weeks after orthotopic liver-injection. Anti-TM4SF reagents blocked their metastasis to distal intestinal organs. Altogether, our results provide evidence that TM4SF5 promotes self-renewal and CTC properties supported by CD133+/TM4SF5+/CD44+(TM4SF5-bound)/ALDH+/ CD24- markers during HCC metastasis.[BMB Reports 2015; 48(3): 127-128]
