Lee, Chang-Seok,Cho, Yong-Chan,Shin, Hyun-Chul,Lee, Seon-Mi The Ecological Society of Korea 2006 Journal of Ecology and Environment Vol.29 No.4

Landscape changes for 20 years between 1981 and 2001 in the Wangsuk stream basin located on the central Korea were investigated on the basis of physiognomic vegetation map made from the aerial photograph interpretation and field check. Changes of landscape structure were noticeable in agricultural field and forest landscape elements. Changes in the agricultural fields due to transformation of agricultural pattern into the institutional agriculture dominated landscape change, although urbanization also contributed to such change. The former change due to change of food production structure originated from socio-economic development during this period and the latter to the overpopulation of Seoul. As energy sources for heating and cooking, fertilizer, and fodder for livestock transform from plant materials to fossil fuel, manufactured one, and grain, succession of forest escaped from direct human disturbance dominated change of landscape structure in forested land. Differently from the positive landscape change in the upper area, change in the lower area deteriorated landscape quality by increasing artificial land. It was estimated that such landscape deterioration in the Wangsuk stream basin would influence water quality of the stream. In order to realize sustainable land-use against such environmental degradation, systematic environmental management based on landscape ecological perspective such as "an eco-plan for creating riparian vegetation belt," which is under preparation by Ministry of Environment, was recommended.

이성선 시의 주요 이미지에 관한 연구

Lee Seong-Seon's father went into North Korea. His family came to know a tragic fate was coming. Lee Seong-Seon′s poetry shows the self-realization that he overcomes the tragic world view. Therefore, in this study, I examined the images of the worms, the trees and the stars appearing in Lee Seong-Seon′s poetry. The image of the worm reminds us of the poet himself as beggar poet. The tree being the symbol of the communication of the heavens with the earth represents the poet himself and sometimes becomes friends with the poet. Lee Seong-Seon loves the flowers, the birds, the worms, the mountains and the trees as natural things, and the moon, the stars and the music from the sky as the universal objects. Lee Seong-Seon′s father didn't come back home and passed away beyond the 38th parallel. The poet gets very discouraged in the real world and he travels around India. While travelling around India he comes across the well seeing in the midst of the desert, the stars in the sky each other. The image of the stars means the light of love that his father shows to the poet. In his mind the poet realizes that the real things and the imaginary things are combined into one.

Which Environmental Factors Caused Lammas Shoot Growth of Korean Red Pine?

Lee, Chang-Seok,Song, Hye-Gyung,Kim, Hye-Soo,Lee, Bit-Na-Ra,Pi, Jeong-Hoon,Cho, Yong-Chan,Seol, Eun-Sil,Oh, Woo-Seok,Park, Sung-Ae,Lee, Seon-Mi The Ecological Society of Korea 2007 Journal of Ecology and Environment Vol.30 No.1

Lammas growth, a rare phenomenon for Korean red pine (Pinus densiflora), occurred in 2006. Lammas shoots showed higher frequency and longer length in Seoul's hotter urban center than in urban boundary or suburban forest sites. Frequency and length showed a close correlation with urbanization density and vegetation cover expressed in NDVI. Air temperature in the late summer of 2006 was more than $1^{\circ}C$ higher than an average year. Of the predominant environmental signals that modulate bud flush, only temperature changed significantly during the year. Differences in temperature between the urban centers, urban boundaries and suburban forests correlated with varying land-use density. The rise in temperature likely spurred lammas growth of the Korean red pine. Symptoms of climate change are being detected throughout the world, and its consequences will be clearer in the future. Considerate interest in the responses of ecological systems to the variable changes is required to prepare for unforeseeable crises. Monitoring of diverse ecological phenomena at Long Term Ecological Research sites could offer harbingers of change.

Skilled and experienced anestheia is of great importance for patients undergoing orthotopic liver transplantation, because of multiple preexisting medical problems in such patients as well as the intraoperative problems of rapid hemodynamic, metabolic, and coagulation changes. In this study, the intraoperative hemodynamic and laboratory data were analyzed in ten dogs that underwent an orthotopic liver transplantation procedure by veno-venous bypass using Biopump. Liver transplantation can be divided into three distinct periods: stage I, or preanhepatic stage, which begins with the induction of anesthesia and continues until cross clamping of portal vein and IVC; stage II, or anhepatic stage, which begins at the anhepatic time and continues until the donor liver is reperfused by the recipients circulating blood; and stage III, or postanhepatic stage, which begins at the time of reperfusion and continues until the end of surgical procedure. The hemodynamic changes at the time of IVC and portal vein cross clamping were decreases in CVP, PCWP, and pulmonary artery pressure in spite of using Biopump. The significant metabolic alternations during anhepatic stage were decrease in blood glucose levels and increase in blood lactate levels. The more significant hemodynamic changes occurred at the time of reperfusion. Systolic pressure decreased suddenly to 58±6 mmHg and cardiac output decreased to 1.08±0.1l L/min. However heart rate, pulmonary artery pressure, CVP, and PCWP did not change significantly. During stage III, hyperglycemia occurred quite frequently. Significant abnormal coagulation chages could not be found, probably because the dogs were healthy. In conclusion, during anhepatic stage, we have to compensate for alternations of fluid balance. At the time of reperfusion, we should prevent severe hemodynamic changes and treat them immediately if they occur. However, it seems that glucose administration is not necessary to the liver recipient during stage II because there is no significant hemodynamic depression e to hypoglycemia at this time and hyperglycemia occurs later

Seon-u Choi,Ju-Rak Lim,Ju-Hee Kim,Ki-Kwan Lee,Chang-yun Hwang 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.05

This study was conducted to develop the economic threshold for the diamondback moth (Plutella xylostella (L.) on Leaf Broccoli (leaf vegetable) in 2007. To investigate the relationship between initial density of diamondback moth larvae and broccoli leaf yield, experimental plots with five treatments (0, 0.5, 1.0, 2.0, 4.0 larvae per plant) as initial density were established. We inoculated larvae in chesses cloth covering to survey larvae density change. When grown to eat, leaves of broccoli were harvested by periods. 60-70% of larvae were removed whenever we picked the leaves. High levels of larvae were associated with significant reductions in leaf yield. There were 85%, 64%, 58%, and 56% yield reductions from the diamond back moth larvae density in 0, 0.5, 1,0, 1.5, 2.0 per plant, respectively 25days after larvae inoculation. The regression equation used to predict leaf yield based on the number of initial larvae density per a plant was y=1635-393x(R2=0.79***). The economic injury level of diamondback moth on leaf broccoli was 2-3 larvae per 10 plants for a damage level of 5%. The economic thresholds was 1-2 larvae per 10 plants. Thus, the diamond back moth management should be initiated 1-2 larvae occurrence per plant.

우리나라의 주택 임대차에 대한 문제는 사회변동에 따라 급격하게 변화되고 있는 실정이다 오히려 주택가격에 인접하는 전세가 나오고, 또한 경매가 이루어질 경우에는 천세금을 회수 받지 못할 정도의 금액이 상회하는 주택들이 나오기 시작하면서 크나큰 사회적 문제로 발전하고 있고 정부는 이에 대한 대책마련에 고심하고 방안을 찾고 있는 실정이다.그래서 우리와 유사한 일본의 주택과 관련한 제도를 살펴보고, 현행 일본의 행하고 있는 차지차가법은 건물의 임대차에 관련해서는 등기가 되어있지 않아도 건불의 인도만으로 효력이 발생한다고 규정하고 있으며(차지차가법제31조 제2항), 또한 물건의 취득만으로도 임대차계약상 대항력을 주장 할 수 있다.일본 차지차가법상 방안제도라 할 수 있고 정당한 사유제도는 임차인에 대한 존속보호와 관련하여 사회적으로 중요한 역할을 하고 있는 점에서 우리와는 특이한 제도라 할 수있다 따라서 본 논문은 일본의 차지차가법 중에서 주택임차인에 대한 보호에 대해서는 존속보호가 정당한 사유제도로 이루어지고 있는데, 차가의 경우 대항요건에 관해서 인도만으로 대항요건을 갖추고, 또한 1년 미만 정할 수 없게 하면서 최장 20 년으로 하고 있는 부분을 찾아보고, 또한 임대차기간에 한하여 계약 갱신을 특약으로 정한 특약은 ‘정당한사유’를서변에 기재하여야 한다고명시하고, 갱신에 있어서도 사전통지가 반드시 있어야 하며, 이에 대해서 정당한 사유에 대한 판단기준에서 문제되어지고 있는데 이것은 일본의 판례에서도 정당한 사유에 대해 중요하게 다루어지고 있는 것이 일본의 독특한 제도이면서, 결국 약자의 입장을 보호하려는 취지가 강하다는 것이다 그래서 현재일본에서 행하여지고 있는 차지차가법과 관련하여 고찰을 통해 우리의 주택임대차보호제도에 대한 시사점을 제시하고 있다.

간 허혈성괴상의 CT소견에 대한 실험적 연구 : 간실질 및 피막의 경시적 변화와 병리조직의 비교 Changes of CT Findings of Liver Parenchyama and Capsule with Time Lapse Correlated with Histopathology

김창근,김강득,최시성,정선관,노병석,원종진 圓光大學校 醫科學硏究所 1994 圓光醫科學 Vol.10 No.1-2

In order to evaluate CT findings with time and to confirm the capsular structure correlating with its histopathologic findings, we experimentally induced ischemic necrosis of liver in 20 rabbits. Incision of the abdomen was performed under anesthesia. Ligation of hepatic artery, portal vein and hepatic duct of right inferior posterior lobe of the liver after injection of macroaggregated albumin into right inferior posterior portal vein in order to prevent from developing collateral circulation as possible. Precontrast and postcontrast enhanced CT images were obtained at 1. 2. 4 days and 1, 2. 4. 6 weeks after induction of ischemic necrosis. Necrotic area in the liver showed homogeneous low density compared to normal liver, and no contrast enhancement after contrast material administration, and marked volume loss with time. CT attenuation value of necrotic area at 1 day(36.7±6.4 M±SD, Hounsfield unit) approached to two third of that of normal liver(56.3±7.3) and showed no significant change until two weeks but increased significantly after four weeks. On contrast enhanced CT images, capsular structure was obsereved as a high density rim along the liver surface of the necortic area in 8 of 15 cases. From the first day on, homogenous ischemic or coagulation necrosis was observed but rarely findings of edema, hemorrhage and cystic change were observed on histopathologic specimen. In all of the histologic samples taken from 10 cases during th 2nd to 6th week, fibrous thickening with rich vascularity was observed along the surface of the necrotic area. In conclusion, ischemic necrosis of the liver showed homogeneous low density and no contrast enhancement. CT attenuation value of necrotic area increased significantly with time associated with markedly decrease in volume. Capsular structure attributed to the hypertrophy of the liver capsule and rich vascularity within it.

This study defined the way to distribute power of forward channel and suggested a new model for prediction power in order to minimize the deterioration of call quality and performance in the CDMA mobile communication system of narrow band using 1.2288MHz of narrow band. Each change in Ec/Io was measured for the factors affecting wireless environment(e.g. the changes in power of overhead channel, the changes in a number of call channel, and the increase in interference from the additional facilities of adjacent base station or other systems) to know the influence on the wireless environment of forward link. The new way for power distribution to a base station in operation and its validity was checked by comparing before and after test.

국어 인용표지 ‘이라고, 고’의 문법적 특성

송창선(Song, Chang-seon) 한국어문학회 2016 語文學 Vol.0 No.131

The aim of this thesis is to find out the grammatical properties of ‘-irago’ in direct quotation and ‘-irago, -dago, -(eu)niago, -(eu)rago, -(eu)mago’ in indirect quotation. Most Korean linguists regarded the embedded clause in direct quotation as a nominal clause or an adverbial clause. But I insist that the embedded clause in direct quotation is an adverbial clause in that it can be substituted by ‘ireokhe’. And Most Korean linguists regarded ‘-irago’ in direct quotation as the case marker. But I insist that ‘-irago’ is not the case marker, because it can be analyzed into ‘i-’(the stem of ‘ita’), ‘-ra’(<-ta) and ‘-ko’(ending). So far, some Korean linguists regarded ‘-irago, -dago, -(eu)niago, -(eu)rago, -(eu)mago’ in indirect quotation as the endings, and others regarded ‘ko’ in these as the case marker. But I insist that ‘-irago, -dago, -(eu)niago, -(eu)rago, -(eu)mago’ is not a grammatical unit, because the prefinal endings like ‘-(eu)si-, -deo-, -eoss-, -gess-’ can be inserted into ‘-irago’ etc. I also reveal that ‘-go’ in ‘-irago, -dago, -(eu)niago, -(eu)rago, -(eu)mago’ is not the case markers but the endings, in that we can integrate ‘-go’ with final endigs ‘-ira, -da, -(eu)nia, -(eu)ra, -(eu)ma’.
