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.

Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.

Hydrogen Behavior in Ti-Added Reduced Activation Ferritic-Martensitic Steels

Kang‑Mook Ryu,Dae Geon Lee,Joonoh Moon,Chang‑Hoon Lee,Tae‑Ho Lee,Jae Sang Lee,Dong‑Woo Suh 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.3

Hydrogen behavior and corresponding mechanical degradation were examined in TaTi-RAFM and EUROFER97 steels. Increased Ta content with Ti addition decelerates the hydrogen diffusion but increases the solubility in the lattice. It ismainly led by the higher fraction of Ta-rich MC carbides and dislocation density in TaTi-RAFM steel. Overall activationenergy of hydrogen trapping of investigated steels is evaluated to be 25.3 ~ 25.6 kJ/mol in the tempered condition. The activationenergy increases to nearly 30 kJ/mol when the steels are re-austenitized and quenched. Higher activation energy withincreased dislocation density indicates that the dislocation provides for trap site with higher activation energy than Ta-richMC carbide. Mechanical degradation by hydrogen with respect to the yield strength, tensile strength and uniform elongationcould not be observed in all investigated steels. The presence of hydrogen only has influence on the loss of post-uniformelongation. For a given charging time, the loss of post-uniform elongation is more remarkable in TaTi-RAFM steel due tothe larger hydrogen uptake.

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.

Strategic Metamorphosis from Sisyphus to Chameleon? North Korean Security Policy and Military Strategy

( Sung Hack Kang ) 한국국방연구원 1995 The Korean Journal of Defense Analysis Vol.7 No.1

National security is basically an ambiguous symbol. Like a chameleon, it has been determined by the supreme decision maker of a nation, depending upon the given spatial and temporal conditions. Nevertheless, national security has been conventionally understood to protect, preserve and defend the lives and properties of the people and their territory. To put it differently, it has meant military defense from the external military threat. But since the end of War II, its meaning has been extended beyond any material damage to include the protection of the vital values of a nation. Then, the protection of existing vital national values through the maintenance of the status quo is the first imperative for government policy, which can employ all kinds of means: political, economic, diplomatic, cultural, and military methods. Among those methods, the military one has been referred to as military strategy. The military strategy of most nations adopted a defensive attitude, namely deterrence to maintain the status quo, which is the first objective of their security policies. Historically, only the nations with revisionist and expansionist goals adopt an offensive military strategy. Such nations were many in history, but they have been rare during specific periods. North Korea has been one of these nations. With an expanded definition of security-the communization of the whole Korean peninsula-the Kim II Sung regime has tried to achieve this anti-status quo positive goal by means of military power, but has failed. For him, war is continuation of the revolution by other means. He can be said to have followed the principle of simplicity in military strategy by consistently pursuing communist unification. However, a chance for the unification of the Korean peninsula by means of a second surprise attack has not come. The continuous presence of American troops in South Korea has almost certainly assured North Korea of another defeat. However, Kim II Sung`s belief in and adherence to a revolutionary war dogma made him almost blind to the need for being faithful to the South-North dialogue. Kim II Sung has waited for a fortuitous opportunity to come. He believed that after the complete pullout of US troops from South Korea, the "center of gravity" of South Korea would return to Seoul and be limited there. He then would be able to gain a victory in his revolutionary war through an offensive strategy as the North Vietnamese did. He waited for the culminating point of offensive, holding the communist view that history was on his side. However, history has turned out to be not on his side. By the present moment, the Kim Jong-il regime has not yet presented the new security policy. It is not clear whether North Korea will abandon the ultimate goal it has continued to pursue during the past half a century, that is, the communization of the Korean peninsula, or will change its military from offensive to defensive strategy by adapting the deployment of its military forces. However, one thing is clear that it will never be easy for the North Korean regime to change radically its traditional military strategy. North Korea has pursued the goal of communist unification of the whole Korean peninsula by military forces like a Sisyphus. The glaringly increasing gap between its goal and its ceaseless efforts might lead one to apply Santayana`s definition of a fanatic, rather than the myth of Sisyphus, as one who redoubles his efforts as he moves further away from his goal. In any case, a Sisyphus cannot become a chameleon at will, because of the law of inertia also works in the political world.

Nurses' management of older patients with post-anesthesia delirium: A Q methodology approach

Kang,Minyeong(Minyeong Kang),Kim,Eun Young(Eun Young Kim),Chang,Sung Ok(Sung Ok Chang) 한국노인간호학회 2022 노인간호학회지 Vol.24 No.4

Purpose: This is an analysis of the experiences of nurses in Post Anesthesia Care Units (PACUs) in caring for older patients with emergence delirium using the Q-methodology. Methods: The Q-methodology, which is used to explore and understand human subjectivity, was applied. Thirty nurses who had experiences in providing nursing for delirium in older patients after surgery in a PACU participated in this study. Results: This study revealed three factors regarding the frame of reference of PACU nurses in detecting and managing older patients' emergence delirium: “detect the deviant changes leading to instability”, “focus on the patient’s degree of cognitive recovery within the framework of recovery time”, and “awareness of possible clues based on the patient’s underlying disease(s)”. Conclusion: These findings are expected to be utilized as a basis for more practical and accessible PACU nurse delirium education that reflects nurses’ subjective viewpoints explained by the three identified factors.

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.
