Probing Cultural Elements within Literature: A Lesson Plan to Expand Understanding
( Kim¸ Haeyoung ) 동국대학교 영어권문화연구소 2017 영어권문화연구 Vol.10 No.2
The integration of language, literature, and culture in the foreign language classroom is a challenge to educationists who struggle to devise a way to achieve the goal of raising individuals equipped with communicative skills founded on solid intercultural understanding. This paper explores teaching strategies that move away from the traditional teacher-centered foreign language literature instruction model and embrace more actively a learner-centered model in which groupwork and workshop-style presentation were introduced to the classroom. Using 9.11.01: The Skyscraper and the Airplane by Adam Goodheart as the main reading text, students engaged in close reading of the literary text, group projects in preparation for class presentation, and workshop-style class discussions. The process enabled students to reflect upon their reading strategies used in understanding the text, method of research for information, and interpersonal and presentation skills. Incorporating cultural factors related to literary texts with learner-centered group projects proved an effective way for students to become motivated learners and critical thinkers in addition to building knowledge on cultural matters and communicative skills.
Characterization of Synthetic Polyamides by MALDI-TOF Mass Spectrometry
Haeyoung Choi,최은경,Eun Kyung Yang,Sungwoo Jang,Chan Ryang Park* 대한화학회 2007 Bulletin of the Korean Chemical Society Vol.28 No.12
MALDI-TOF-MS technique was applied to obtain structural and compositional information of synthetic polyamides, Nylon6 and Nylon66. Mass spectra of both the original and the hydrolyzed polyamide samples were analyzed using the self calibration method as well as the internal calibration method with the standard materials of known masses. The MALDI-TOF mass spectra of Nylon6 samples showed the presence of protonated, sodiated, and potassiated ions that were assigned to cyclic and NH2/COOH terminated linear oligomers. From the MALDI-TOF mass spectra of Nylon66 samples, the potassiated linear oligomers with three different end groups are identified as well as the cyclic oligomers, i.e., NH2/COOH terminated oligomers, NH2/NH2 terminated oligomers, and COOH/COOH terminated oligomers. Full characterization of the molecular species and end groups present in the polyamide samples has been achieved, and also the changes in mass spectral patterns after the hydrolysis of the samples are presented.
The use of Accruals for Tax and Financial Reporting Purposes and Stock Market Response

This study investigates the effect of book tax conformity in Korea on the use of accruals. Specifically, we use a sample of 4,331 Korean firms and decompose their total accruals into book tax accruals and book only accruals. Book tax accruals are defined as accruals that affect both taxable income and reported earnings. Book only accruals are defined as accruals that affect solely reported earnings and have no effect on a firm’s taxable income. We anticipate that managers will decrease taxable income by recording book tax accruals that have relatively high book tax conformity to reduce their tax liability. Managers are expected to attempt to increase book income through book only accruals. We also examine the market response to the firms using these accruals in different directions. Our evidence demonstrates that firms are increasingly using income decreasing book tax accruals to decrease taxable income, and using book only accruals to increase financial income and compensate potential non tax cost such as financial reporting costs. In addition, our results show that the market correctly assess the management of accruals even when the uses of two accruals offset each other.

Butanol is a promising alternative to ethanol and is desirable for use in transportation fuels and additives to gasoline and diesel fuels. Microbial production of butanol is challenging primarily because of its toxicity and low titer of production. Herein, we compared the transcriptome and phenome of wild-type Escherichia coli and its butanol-tolerant evolved strain to understand the global cellular physiology and metabolism responsible for butanol tolerance. When the ancestral butanol-sensitive E. coli was exposed to butanol, gene activities involved in respiratory mechanisms and oxidative stress were highly perturbed. Intriguingly, the evolved butanol-tolerant strain behaved similarly in both the absence and presence of butanol. Among the mutations occurring in the evolved strain, cis-regulatory mutations may be the cause of butanol tolerance. This study provides a foundation for the rational design of the metabolic and regulatory pathways for enhanced biofuel production.

Purpose: This study was performed to evaluate prognostic factors for survival from first relapse (SFFR) in stage I.III breast cancer patients. Materials and Methods: From June 1994 to June 2008, 3,835 patients were treated with surgery plus postoperative radiotherapy and adjuvant chemotherapy for stage I.III breast cancer at Samsung Medical Center. Among them, a total of 224 patients died by June 2009, and 175 deaths were of breast cancer. Retrospective review was performed on medical records of 165 patients who met the inclusion criteria of this study. Univariate and multivariate analysis were done on survivals according to variables, such as age, stage, hormone status of tumor, disease-free interval (DFI), sites of first failure, number of organs involved by recurrent disease (NOR), application of salvage treatments, and existence of brain or liver metastasis (visceral metastasis). Results: Patients’ median overall survival time was 38 months (range, 8 to 123 months). Median SFFR was 17 months (range, 5 to 87 months). Ninety percent of deaths occurred within 40 months after first recurrence. The patients with SFFR ≤1 year had tendency of triple-negativity, shorter DFI (≤2 years), larger NOR (>3), visceral metastasis for first relapse than the patients with SFFR >1 year. In multivariate analysis, longer DFI (>2 vs. ≤2 years), absence of visceral metastasis, and application of salvage treatments were statistically significant prognosticators for longer SFFR. Conclusion: The DFI, application of salvage treatments, and visceral metastasis were significant prognostic factors for SFFR in breast cancer patients.
