들민달팽이의 배자발육은 해부현미경으로 관찰하였다. 산란 후 4일이 경과면서 발육이 급격하게 진전되어, 10일이 지나면서 난 내에서 들민달팽이 유충의 형태를 갖추고, 12일째 부화하였다. 들민달팽이의 배자발육에 따른 난황단백질의 변화는 산란 1일째, 3일째 및 6일째 알의 난황단백질을 전기영동방법으로 분석하였다. 그 결과 배자발육과 함께 급격히 감소되는 난황단백질 관련 밴드를 관찰할 수 있었다. We characterized embryogenesis and egg proteins of Variable field Slug, Deroceras varians. The embryogenesis was observed by light microscopy. The eggs were hatched at the twelfth day after oviposition. The egg proteins of the first day, third day and sixth day after oviposition were analyzed by native-and SDS-PAGE analyses. The results showed that yolk proteins are gradually decreased during embryogenesis.

Chemical feedstocks and fuels from biomass sources are rapidly attracting our attentions, today. The widespread uses of renewable biomass sources are inevitable for the near-term demise of petroleum sources. The liquefaction of wood (Pinus rigida, Populus euramericana, Salix pseudo-lasiogyne) in au toclave gives the following results. The liquid yield and the conversion are increased by using catalysts and Ni is more effective catalyst than bentonite in liquid yield. The liquid yield is maximum at 300℃(85 atm), with Ni catalyst (for Pinus rigida :0.52, for Populus euramericana : 0.53, for Salix pseudo-lasiogyne : 0.46). Populus euramericana gives more higher liquid yield than others in general. The liquid produced by using Raney-nickel catalyst represents higher combustion heat. The amount of produced gas is increased as the temperature increase from 200℃ to 400℃ without catalysts, but, when catalysts are used, that is maximum at 350℃.

On the Acc-ing Construction

본 논문은 영어의 동명사의 여러 종류 중에서 특히 소위 ‘Acc-ing’이라고 불리는 구문의 구조에 관한 연구이다. 그 구조를 분석하는데 있어서, 우선, 선행 논문의 주장을 간단히 살펴보고, 그 문제점을 지적한 뒤, 이 논문들이 다루지 않은 현상인 ‘wh’추출을 설명함에 있어, 기능범주의 핵의 자질이 결정적인 역할을 함을 주장하려 한다.

부정사와 동명사구문의 평행구조

尹恒鎭 水原大學校 2000 論文集 Vol.18 No.-

이 논문은 영어의 부정사 구문과 동명사 구문이 동사의 보충어(complement)로 나타나는 경우에 두 구문사이에 평행구조가 나타난다는 것을 주장하려고 한다. 우선, 종속절의 주어의 종류에 따라 유형을 세 가지로 나눈 다음에 각각의 구문이 통사적으로 그리고 의미적으로 어떠한 공통점이 있는지 살펴보고 그 공통점을 근거로 하여 언어의 대칭성을 보이고자 한다.

영어와 문화 : 영어 단어를 통한 미국 개척사 읽기

윤항진 水原大學校 2020 論文集 Vol.34 No.-

Culture is one of the most important elements in learning a language. To understand a sentence in a language implies to understand cultural elements behind the words which make the sentence. This paper is designed to introduce some important words in the history of American immigration and link them to learning English as a foreign language. Some word formations are also introduced to explain how such words as WASP and Forty-niners are coined. The history behind these words may trigger curiosity and interest for students in learning English.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

본 논문은 영어의 소위 비한정절인 부정사와 동명사의 구조를 규명해 보려는 데 그 목적이 있다. 굴절요소로 나타나는 INFL이 한정절의 핵(Head)이라는 가정하에 본 논문은 비한정절도 to'와 ing'가 INFL을 나타내는 요소임을 주장하고 각 비한정절의 차이는 C(OMP) 투사구조의 존재여부와 INFL의 자질 차이에 있음을 주장하여 한다.

Purpose : To find the cause of root curvature by use of panoramic and lateral cephalometric radiograph. Materials and Methods : Twenty six 1st graders whose mandibular 1st molars just emerged into the mouth were selected. Panoramic and lateral cephalometric radiograph were taken at grade 1 and 6, longitudinally. In cephalometric radio graph, mandibular plane angle, ramus-occlusal plane angle, gonial angle, and gonion-gnathion distance (Go-Gn distance) were measured. In panoramic radio graph, elongated root length and root angle were measured by means of digital subtraction radiography. Occlusal plane-tooth axis angle was measured, too. Pearson correlations were used to evaluate the relationships between root curvature and elongated length and longitudinal variations of all variables. Multiple regression equation using related variables was computed. Results : The Pearson correlation coefficient between curved angle and longitudinal variations of occlusal plane-tooth axis angle and ramus-occlusal plane angle was 0.350 and 0.401, respectively (p<0.05). There was no significant correlation between elongated root length and longitudinal variations of all variables. The resulting regression equation was Y=10.209+0.208X_(1)+0.745X_(2) (Y: root angle, X_(1): variation of occlusal plane-tooth axis angle, X_(2): variation of ramus-occlusal plane angle). Conclusion: It was suspected that the reasons of root curvature were change of tooth axis caused by contact with 2nd deciduous tooth and amount of mesial and superior movement related to change of occlusal plane.

1. Entomological field surveys on the moth fauna at Gucheondong, Muju, Cholla Puk Do were undertaken in July 4, 21 and August 13 in 1978 respectively. In addition to the above collected moth specimens, the museum specimens which were collected in 1976 from the same area were also examined in this study. 2. As a result, a total of 139 newly recorded species of Gucheondong area which comprises 18 families were recovered. Therefore, moth fauna form the area recorded so far, are amounted to the total of 166 species belonging to 18 families. 3. In this survey and study, the following twelve species are recorded newly from Korea.

본 논문은 내재핵 관계구문에서의 '것'의 특성에 주목하면서 한국어 단어 '것'의 통사적 정체성을 밝히는데 그 목적이 있다. 이 단어는 원래 불완전명사로 분류되기도 하는데, 그 이유는 혼자서 쓸 수 없기 때문이다. 이 논문에서는 우선, 여러 용도로 쓰이는 '것'의 분포에 대해 살펴보고, 그 통사적 특성을 논하고자 한다. 우선, 보문소로 쓰이는 '것'에 대해 알아보고, 관계절 구문의 '것'과의 차이점을 논하고자 한다. 또한, '것'을 보문소로 보아야 한다는 장세은(1994)의 주장을 조목별로 따져보고 그 문제점을 지적하고자 한다. 이러한 여러 특성에 기초하여 우리는 이 논문에서 '것'이 허명사임을 주장하려한다. 또한, '것' 분열구문에서의 '것'도 마찬가지로 허명사로 볼 수 있다고 주장하며, 이러한 주장이 다른 주장보다 우월함도 보이려한다.
