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.

Investigation of the April 2000 forest fire damage in Kang-won Province, Korea, using RADARSAT data

Kang, Sung Chul,Seo, Jin Won,Lee, Tae Hee,Park, Sang Eun,Hong, Suk Young,Moon, Wooil M. 대한원격탐사학회 2000 International Symposium on Remote Sensing Vol.16 No.1

The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

9ㆍ11 테러와 김정일 정권의 생존 전망

강성학 고려대학교一民국제관계연구원 2002 국제관계연구 Vol.6 No.1

It is commonly mentioned that everything has changed since the events of September 1, 2001. Evidently some things have changed; others have been reinforced; and others have become visible though previously had went unrecognized. America's war against terrorism will certainly have an impact on many states. North Korea has been one of the states on the list of terrorist states. Then we must raise the question, "Will the DPRK survive, say, by the year 2020?" The Kim's regime could be, like any other state's political regime, threatened to be overthrown, in theory, from "within" as well as from "without." Firstly, let me examine the possibility for Kim's regime to bo overthrown from within. Until now, there has been no known factor for us to speculate that there any noteworthy political opposition to Kim's regime within North Korea's borders. There has never been any report that may indicate even a symptom of rebellion against the leadership of the two Kims (i.e. Kim Il Sung and Kim Jong Il). In midst of the serious situation of nationwide starvation, there were many North Koreans who wanted to escape from North Korea at the risk of their lives. However, there were no people who dared to challenge Kim's leadership. Since he became the heir of Kim Il Sung in February 1974, Kim Jong Il consolidated his personal power basis throughout North Korea's governmental organizations and virtually ruled North Korea for the last almost three decades. Kim is a great pretender. Holding up the picket saying "Our way to Socialism" high, he pretends to be an infallible Philosopher-King who has perfect knowledge of the changing outside world and how to cope with it. But he is nothing but a violent tyrant. We know that the tyrant Stalin was not overthrown from within while he was alive, however terrible the tyrant might have been, not to mention Hitler(Unser Fuhrer), Mussolini(Il Duce) and Hirohito(Tenno Heika). Like his historical predecessors, "Supreme Leader Kim"(Dear Soo Ryong) in North Korea is not likely to be overthrown from within. Secondly, then, is there any possibility for Kim's regime to be overthrown from the outside? If Kim Jong Il is content in maintaining the status quo on the Korean Peninsula, it could be safely said that no outside powers including the United States have intentions to overthrow the Kim's regime in North Korea. Besides, China is and ally of a kind in that it would not let North Korea be unified by South Korea, as made clear by the massive military intervention during the Korean War to maintain North Korea as a separate political entity, most friendly to or at least not hostile to China. However Kim Jong Il continues to pursue a positive goal, an ambitious, revolutionary, revisionist, self-imposed historical mission to unify the whole Korean peninsula on his own terms by his own strategy, as his father Kim Il Sung did throughout his life time, though without success. In other words, Kim continues a revolutionary war against South Korea. For Kim, war is merely a continuation of politics by other means. Such a strategic mindset was handed down from Clausewitz to Lenin to Stalin and Mao to Kim Il Sung and finally to Kim Jong Il. Yet Kim Jong Il has also a distorted form of the Clausewitzean dictum. For Kim Jong Il, a hereditary prince, as for Machiavelli, "the arts of peace are those of non-violent war by fraud." For Kim, peace also is a mere continuation of war by other means. Kim Jong Il employed the strategy of mendicant brinkmanship to outside powers. They could not ignore Kim. North korea's internal disaster will explode over Northeast Asia. To prevent that, the U.S. must sustain the repugnant regime. Food and energy donations propped up the most repressive government in the world, because North Korea's missiles with nuclear, biological or chemical bombs can reach South Korea and Japan, two key U.S. allies. Kim's mendicant brinkmanship has been successful until now. U.S. strategy since the Cold War has focused on conventional regional war. The geographic scale of this war can be specified since it comes from the Korean peninsula. Within it, the U.S., together of course with South Korea, has prepared for conventional warfare in which nuclear, chemical, biological weapons, and ballistic missiles are not to be used. This plays to American strengths. No nation could stand up to the United States in such a war. But North Korea has been trying to overcome the U.S. psychological and military advantages. North Korea has been diversifying into nuclear, chemical and biological weapons. In Clausewitz's terminology, biological weapons move the center of gravity of the war from the front, where the U.S. has advantage, to the rear, the population centers, where the U.S. clearly does not. Germ weapons target innocent lives, not military force. It would be suicidal for North Korea to launch such an attack, but the possibility it might do so makes Washington thread more carefully, especially after the tragic incident of September 11, 2001. North Korea's hitting Seoul or Tokyo or both cities with anthrax bombs will be horrible. Therefore, North Korea may be treated more gingerly. There is no doubt that the inter-Korea summit meeting was an historic event. It is a timely intriguing question whether the inter-Korea summit meeting will be a historical turning point for Korea's national history of turn out to be nothing but deceptive pageantry carefully choreographed by Kim Jong Il. By now, most indications in the post-summit period suggest that hopes were raised too high and too prematurely. One thing is still clear; Kim Jong Il has no intention to change his exclusive policy, not to mention not giving in to external pressure to compromise. Kim Jong Il will continue to behave like a hedgehog toward the outside world, holding up the anachronistic icon of "Juche" high. As Aristophanes said, "You can not teach a crab to walk straight." Despite Hamish McRae's optimistic prediction that it is very hard for him to see anything other than unification of North and South by 2020, South Korea's sunshine will not be able to lighten Kim's kingdom of darkness as long as Kim Jong Il is alive, even by the year 2020. the inter-Korean relationship is ruled by a kind of unit-veto system. Like the weather, we can always talk about it, but no one can do anything about Kim's totalitarian regime in North Korea especially as long as China supports it. In short, my crystal ball is not clear, but at least I can say that the DPRK will not be overthrown from the outside, either. At the dawn of the twenty-first century, it would be better for us to remind ourselves of what English poet William Blake sang at the dawn of the nineteenth century: "You throw the sand against the wind, And the wind blows it back again."

全南地域 傳統磁器 活性化 方案에 關한 硏究

姜星坤,曺成南 호남대학교 1998 호남대학교 학술논문집 Vol.19 No.2

We all recognize that Korea has created its excellent cultures in the traditional porcelain with different characteristics in different eras of its long history. Especially, Chon-nam Province has formed one of the most important and superior ceramic cultures in Korea; and also it has played a significant role in tile distribution of its workshops and its history. Judging from the height-level Koryo Celadon Porcelain in Kang-jin which was created with mature ceramic-making techniques, Green Celadon Porcelain in Hae-nam which has been asked for some historical and academic researches lately again, Poonchong-Sagi in Mu-an, Ko-heung and other places around Mt. Mu-deung which represents the national pictorial sentiments, and Everyday Porcelain in Mok-po which still stands for the modern practicalceramic, it is absolutely true that Chon-nam Province is a warehouse of ceramic cultures in respects of its purity and tradition. So, we have to be proud of this brilliant property of the traditional cultures and the regional sentiments, and also all the people in Chon-nam Province must take the responsibility for conserving and developing them thoroughly in scientific ways by studying every respect of ceramic. Ceramic is difficult to be activized only by the traditional craftmen but we should take into account various measures such as improving: the work conditions, proper guidance for quality-development, back-up policies from the centraland local governments, promoting the social understanding on our ceramic, expanding its demand, and so on. Even though some of suggestions from the thesis, such as establishment of provincial procelain institute and educational facilities, programs for promotion and advertisement, connection between cultural festivals and tourist industry, and political supports, are not good enough to improve and activate our traditional china-ware in chon-nam province, we have to make efforts to carry out these plans because they will influence strongly on development of our province in the new era of localization, and on its qlobalization.

Objective: The aim of this study was to investigate the clinical significance of myocardial injuries in patients with nontraumatic intracranial hemorrhage by identifying the occurrence of myocardial injury and defining its correlation with subsequent cardiovascular events. Subjects and methods: One hundred twenty-four patients with nontraumatic intracraninal hemorrhage presented to the emergency department within six hours from onset of symptoms were enrolled. Brain CT, serial electrocardiography, and echocardiography were done at the emergency center. Blood samples for troponin I and creatine kinase(CK)-MB were drawn immediately and eight hours after admission, Troponin I and CK-MB were measured using a chemiluminescent immunoassay, respectively. Results: Electrocardiographic and echocardiography abnormalities were found in 65 cases(52.4%) and 21 cases(17%), respectively. Serum troponin I and creative kinase-MB were increased in 35 cases (28.2%) and in 58 cases(46.8%), respectively. Abnormal findings of echocardiography and ECG, as well as elevated levels of serum troponin I and creative kinase-MB, were associated with an increased risk of cardiovascular event and survival. Logistic regression analysis revealed that an abnormal echcocardiographic finding and elevation of serum troponin I were factors associated with the occurrence an adverse cardiovascular event and that electrocardiographic abnormalities and initial mental status were factors associated with poor prognosis. Conclusion: This study reveals that actual myocardial injury develops in a significant proportion of patients with nontraumatic intracranial hemorrhage and that the development of the myocardial injury is associated with an adverse cardiovascular event that occurs during admission.

A review of diffraction phenomena for double slit and regularly triangular aperture has been done. First, as a width b and a space d of double slit vary, a diffraction pattern has been calculated by theory. Second, an intensity of diffraction light and separation between fringes for slit has been measured. And, we can expect that the calculated diffraction pattern for a regularly triangular aperture has three symmetric axes.

Nitric Oxide에 의한 난소 과립세포의 Apoptosis 조절에 대한 연구

강한승,이석자,김외리,이채관,신창숙,김성태,강성구 인제대학교기초과학연구소 1998 자연과학 Vol.2 No.-

여포의 퇴화가 진행되는 기작에서 apoptotic cell death 와 nitric oxide (NO)의 연관성에 관하여 실험하였다. 난소의 apoptosis는 GnRH에 의해 유도되고 스테로이드에 의해 억제된다. 여포에서 과립 세포의 apoptosis에 대한 호르몬의 영향과 NO 생산효과를 조사하기 위하여 중간크기 (직경 5-6 ㎜)의 여포에서 non-apoptotic 과립세포를 분리하여 스테로이드, GnRH agonist, GNRH agonist+SNP, 그리고 NO 공여체인 SNP를 처리하여 24시간동안 배양하였다. 배양된 과립세포에서 게놈 DNA를 추출하여 apoptotic DNA절편화 경향을 알아보았고, 배양액과 griess reagent를 반응시켜 nitrite 농도를 측정하였다. 스테로이드 호르몬을 처리하였을 때, 대조군에 비해 NO 생성이 다소 증가하였으며 apoptotic DNA 절편화도 억제되었다. GnRH agonist 처리군에서는 apoptotic DNA 절편화가 가속화 양상을 나타내었으며 NO 생성은 다소 감소하였다. 그러나 GnRH agonist+SNP 그리고 SNP 처리군에서는 apoptotic DNA 퇴화가 억제되었으며 NO 농도는 대조군에 비해 현저히 높았다. 위의 실험 결과로 보아 과립세포 분화와 여포성숙과 퇴화과정에서 호르몬과 NO가 밀접한 관련이 있는 것으로 사료된다. To study the regulation of porcine follicular cell apoptosis by steroids, GnRH agonist and nitric oxide, we have analyzed DNA fragmentation, the hallmark of apoptosis, and nitrite production in porcine granulosa cells. In, ovarian apoptosis is induced by GnRH but is prevented by steroids. Apoptosis is confined to the granulosa cells but it was not clear whether apoptosis of granulosa cell was regulated by NO in vitro. So non-apoptotic granulosa cells isolated, grown at 37℃, for 24 hrs, and treated with / without SNP, GnRH agonist, and sterioid, respectively. In cultured granulosa cells were used to extract genomic DNA and culture media was assayed for nitrite concentration. Nitrite production of culture media was increased and apoptotic DNA fragmentation was supressed in SNP treated groups, GnRH agonist+SNP, and estrogen, progesterone. Nitrite concentration in culture media was decreased and apoptotic DNA was induced treated with GnRH agonist. These data suggest that NO production and apoptosis may be involved of granulosa cell differentiation and ovarian follicular atresia by SNP, estrogen and progesterone. Moreover, NO can overcome the granulosa cell apoptosis induced by GnRH agonist.
