Examining Generalizability of Kang's (1999) Model of Structural Relationship between ESL Learning Strategy Use and Language Proficiency

Kang, Sung-Woo 한국영어어문교육학회 2001 영어어문교육 Vol.7 No.2

The present study examined whether Kang's (1999) model of the relationships among language learning strategy use and language proficiency for the Asian students could e applied to a more heterogeneous group. In Kang's study, he collected information of language learning strategies of 957 foreign students learning English as a second language in American colleges through a questionnaire. He also measured the subjects' language proficiency with the Institutional Testing Program TOEFL(Test of English as a Foreign Language). This study analyzed the same data with out the limitation of cultural identity. Structural equation modeling was used to model the relationships among strategy use and language proficiency, Then, the model of the present study was descriptively compared with Kang's (1999) model for the Asian students. The overall flow of the relationship paths appeared to vary very little across the two models, which would have indicated that the generalizability of Kang's (1999) model could be extended more than originally examined.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

대암산 고층습원의 환경변천

강상준,Yoshioka, Takahito 한국육수학회 2005 생태와 환경 Vol.38 No.1

강원도 양구군과 인제군의 경계에 있는 대암산 용늪의 이탄 퇴적물을 사용하여 탄소 및 질소 동위원소비의 해석을 통하여 용늪의 환경변천의 해석을 시도하였다. 표층 0~5 ㎝의 연대는 BP190년, 30~35 ㎝층 및 50~55㎝층에서는 각각 BP870, BP1870년으로 측정되었다. 유기물 함량이 높은 0~55㎝의 이탄층에서 bulk의 퇴적속도는 약 0.4㎜/년으로 계산되었다. 금번 시료를 채취한 지점의 퇴적물 최하층인 75~80㎝층의 ^(14)C 연대는 약 BP1900년으로 측정되었고 50~55㎝와 75~80㎝층의 측정연대가 거의 비슷한 것으로 보아서 용늪의 심층부는 원래의 삼림 토양인 것으로 판단되었다. 50~55㎝층은 모래 성분이 포함되어 있고 또한 유기물 함량이 낮은 것으로 보아 주변 지역의 침식으로부터 유래되었을 가능성이 있다고 판단되었다. 이상의 결과로 부터 본 연구에서 이용한 시료의 채취 지점에서는 BP1900년 경부터 습원화가 되었다고 추정된다. 유기탄소 동위원소비, 총 질소동위원소비는 깊이 방향으로 변동이 보였다. 이러한 사실로부터 대암산 고층습원의 발달과정에 있어서 기후조건의 변동과 함께 질소순환계의 변화도 있었던 것으로 추론 되었다. The environmental change of Yong-nup in Mt. Dae-Am, which is located at the northern part of Kangwon-Do, Korea, was assesed with peat sedimentary carbon and nitrogen isotope analysis. The surface layer of the peat (0~5 ㎝) was 190 year BP, and the middle layers (30~35 ㎝ and 50~55 ㎝) were 870 year BP and 1900 year BP, respectively. Bulk sedimentation rate was estimated to be about 0.4 ㎜ year^(-1) for 0 ㎝ to 30 ㎝ and 0.15 ㎜ year^(-1) for 35 ㎝ to 50 ㎝. The ^(14)C age of the bottom sediment (75-80 ㎝) collected and measured in this study was about 1900 year BP, although it was measured that the ^(14)C of the lowest bottom sediment in Yong-nup was 4105±175 year BP (GX-23200). Since the ^(14)C ages for 50-55 ㎝ and 75-80 ㎝ layers were almost the same as 1890±80 year BP (NUTA 5364) and 1850±90 year BP (NUTA 5462), respectively, we have estimated that the deep layers (55 80 ㎝) in the high moor were the original forest soil. The low organic C and N contents in the deeper layers supported the inference. The sediment of 50~55 ㎝ layer contains much sandy material and showed very low organic content, suggesting the erosion (flooding) from the surrounding area. In this context, the Yong-nup, high moor, of Mt. Dae-Am, might have developed to the sampling site at about 1900 year BP. The δ^(13)C values of organic carbon and the δ^(15)N values of total nitrogen in the peat sediments fluctuated with the depths. The profile of δ^(13)C may indicate that the Yong-nup of Mt. Dae-Am have experienced the dry-wet and cool-warm period cycles during the development of the high moor. The δ^(15)N may indicate that the nitrogen cycling in the Yong-nup have changed from the closed (regeneration depending) system to the open (rain NO₃^-1 and N₂ fixation depending) system during the development of the high moor.

위선암에서 p53과 EGFR 및 PCNA 발현에 관한 연구

강현욱,양승하,강상균 순천향의학연구소 1997 Journal of Soonchunhyang Medical Science Vol.3 No.1

Expression of oncogene in the gastric adenocarcinoma was considered as a determinant factor of cancer progression or prognosis by some authors, however, the results were so fluctuated according to the authors that there was no uniform agreement in their clinicopathological correlation as well as in its practical application. To evaluate correlation between the pathologic finding and the expression of p53, EGFR and PCNA, immunohistochemical studies were performed on paraffin-embedded sections of 84 gastric adenocarcinomas. Pathologic findings were classified as 4 subgroups by their histologic types, differentiation, invasion and lymph node metastasis. The correlation of PCNA labelling index with various clinicopathologic factors and oncogene expression was studied. The results were as follows; 1. p53 expression was seen in 47cases(55.56%) of gastric carcinoma, and correlation between p53 expression with tumor type, differentiation, invasion and lymph node metastasis was not proved. EGFR positive expression was found in 37(44.05%) cases and was increased in advanced gastric carcinoma, and cases of lymph node metastasis. 2. Co-expression of p53 and EGFR was observed in 18 cases(33.33%), suggesting existence of both oncogene in the same case, while both negative cases were 18 cases(33.33%) that suggest the possibility of presence of the other factors. 3. PCNA labelling index was higher in advanced gastric carcinoma and in cases of lymph node metastasis, but there was no statistical significance. 4. There was no statistical significance between PCNALI and p53 expression. 5. PCNALI and EGFR expression was parallel with pathologic finding such as differentiation, progression and metastasis of the carcinoma, these results suggest that there was significant correlation between PCNALI and EGFR. 6. PCNALI was statistically significant between two groups of both p53 and EGFR positive and both negative. 7. PCNALI showed statistical significance between EGFR positive and negative groups in cases of lymph node metastasis. In summary, the value of p53 expression as a prognostic factor was still doubtful but EGFR and PCNA expression tended to be associated with tumor progression and seemed to be objective and reliable prognostic factors, respectively. Combined method of EGFR and PCNA thought to be more helpful in preoperative decision or prediction of prognosis in gastric carcinoma.

Fe^(3+)-Thiourea Redox 계에서 Nylon 66에 Vinyl계 Monomer의 Graft 공중합에 관한 연구(第1報) : Methyl methacrylate의 graft 공중합

강성구,권순채 영남이공대학 1982 論文集 Vol.11 No.-

The graft copolymerization of methylmethacrylate onto nylon 6.6 fibers was investigated in aqueous solution using the ferric chloride - thiourea redox system as the initiator. The rate of grafting was determined by varying the monomer, initiator, and thiourea, the acidity of the medium. The graft yield increases with increasing the initiator concentration up to 2.0×10^-3M/L and thereafter it slows down. The rate of grafting increases with on increase of thiourea concentration. The percentage of grafting increases with on increase of the monomer concentration.

1870~1880년대 고종의 대외관과 자주의식에 관한 연구

강상규 한국방송통신대학교 통합인문학연구소 2010 통합인문학연구 Vol.2 No.1

19세기 동아시아는 그동안 이 지역에서 오래도록 지속되어 오던 중화 질서가 현실적으로 붕괴되고 서구의 근대 국제 질서로 재편되는 지난한 과정 을 겪었다. 한•중•일 동아시아 삼국은 이 과정에서 이른바 ‘예의’ 관념에 입각한 중화 질서에서 부국강병’과 ‘국가 평등 관념’에 입각한 근대 국제 질서로 동아시아 세계를 구성하는 ‘패러다임의 변동’을 겪게 된다. 이것은 동아시아 국가 ‘간’ 관계의 패러다임이 중화 질서하의 조공 책봉 관계’ 및 ‘사대교린’ 관계로부터 근대 ‘국제’ 질서의 수평적이고 독립적일 뿐 아니라, 그만큼 ‘무정부적 인 관계’로 변환하는 것을 의미하는 것이었다. 그러면 19세기 근대 국제 질서라는 상이한 대외 질서 관념과 대면하게 되는 과정에서 주권 국가라는 의미를 가진 자주국 혹은 독립국에 관한 인식은 한국에서 언제부터 생겨난 것일까? 과연 이러한 의식은,기존의 많은 연구들이 전제前提)하는 것처럼,적어도 갑신정변이 일어나기 전까지는 -자주당(自主黨)과 사대당(事大黨)이라는 표현에서 나타나는 것처럼- 정변을 주도한 이른바 ‘급진’ 개화파들의 의식 속에서만 존재했던 것인가? 1870년대와 1980년대 국왕 고종은 어떠한 대외관을 가지고 있었는가? 그는 과연 근대 국제 질서라는 새로운 패러다임에 상응하는 ‘자주’, ‘독립 국가를 만들려는 의식을 가지고 있었는가? 만약 고종에게 ‘자주’에 관한 의식이 존재했다면 그것은 대체로 언제 어떠한 계기에 의해 형성된 것이며,그것의 구체적인 내용은 어떠한 것이었는가? 본 연구는 이러한 물음에 답하기 위해 고종의 정치의식과 ‘대외관’이 어떠한 과정을 통해 형성되었으며 어떠한 내용을 담고 있었는지, 그중에서도 ‘자주’의식의 형성과 그 실천적 의미가 무엇인지를 고찰한 글이다. In the 19th century there was a clash between the Chinese world order and the modern international order. A paradigm shift in East Asia during the 19th century transformed the world order from the basis of ceremony to modern international order by a sovereign state. This entailed a reversal in the “standard of civilization” from the viewpoint of East Asia. Given this, when did a clear perception of a sovereign or independent state appear in Joseon? Did the new perception exist only in the cognizance of several so-called ‘political revolutionaries’ including Kim Ok-gyun? The main purpose of this article is to reexamine the characteristics of the political consciousness and the foreign relations views of King Gojong. What kind of political awareness and foreign cognizance did he have in the 1870s and 80s? Did he have the intention to make his country “an independent state” or “a sovereign state” according to the modern international order? If he did, when did he start to recognize national ‘independence’ as the most important aim? In order to approach these questions, this study pays attention to how the political consciousness and the foreign relations views of King Gojong are correlated with the “internal and external” political changes of the Korean Peninsula within the context of the transformation of the East Asia order.
