An examination of the use of repair strategies of elementary English as a second language (ESL) students

The primary purpose of this study was to explore conversational repair strategies employed by elementary level ESL students in their classroom. This study investigated repair strategies that were employed by ESL students and determined if there were differences in the usage of repair strategies by class types and grade levels. This study examined how elementary ESL students’ repair strategies dealt with communication breakdown in their ESL classroom from a conversation analysis perspective. The data were collected from five participants who were in two different types of ESL classes: (1) instruction centered class; and (2) language related game-playing class. In order to investigate the variable of grade levels, first and second grade students’ ESL class and third and fourth grade students’ tutoring class were chosen. Twenty-four class hours were observed with a video camera. The data were transcribed following the transcription conventions of conversation analysis. The results derived from the study were following; 1. In this study the elementary ESL students used nine types of repair strategies. They were: 1) unspecified, 2) interrogatives, 3) (partial) repeat, 4) partial repeat plus question word, 5) understanding check, 6) requests for repetition, 7) request for definition, translation or explanation, 8) correction, and 9) nonverbal strategies. The elementary ESL students used understanding check and partial repeat more frequently. 2. The findings indicated that both class types and grade levels influenced the types and distribution of the students’ repair strategies. 3. Instruction class produced more amounts of conversational repair than game-playing class. However, in both types of classes, first/second grade students employed understanding check the most frequently, and third/fourth grade students partial repeat the most. 4. In the first/second grade students’ repair practices, understanding check was observed in the teacher’s direction. In the third/fourth grade students’ repair practices, however, understanding check was observed in the content of instruction. Request for repetition and request definition, translation, or explanation were not observed in the first/second grade students’ class but used in the third/fourth grade students’ class. 5. Students’ decisions on the types and frequency of their repair strategies were influenced by their familiarity with the native speakers

Investigating Employee and Customer Perceptions on ICT Utilization: CRM and Policy Implications

Purpose: The purpose of this study is to analyze factors affected by the ICT utilization with perspectives of employees (Study 1) and customers (Study 2) that are rarely approached in previous studies. In particular, this study examined how proposed factors on ICT utilization affect employee satisfaction, organization performance, customer satisfaction, and purchasing decision making. Research design, data and methodology: This study conducted an online survey to measure the effects. Cronbach’s alpha was applied to test reliability and factor analysis was applied to check validity. Multiple regression analysis and ANOVA were applied to test hypotheses. Results: The results of this study found that the effects of self-development and organizational innovation on employee satisfaction were significant for study 1, while the effects of product satisfaction, promotional offers, and customer communication on purchase decision making were significant for study 2. Conclusions:This study provides managerial and policy implications. At the management level, it is necessary to make specific strategies to improve employee and customer satisfaction and organization performance associated with the utilization of ICT. The results of this study suggest that better policy should be prepared by government to foster utilization of ICT infrastructure and to enhance better relationships with employees and customers.2

Sorokdo: From the Island of Stigma to the Island of Historical Reflection

This article focuses on Sorokdo Island (Jeollanam-do, South Korea) as a remnant of the stigmatized landscape reflecting Hansen’s Disease and the Japanese colonial power. Sorokdo began to be stigmatized due to the Japanese colonial rule in the early 20th century when patients with Hansen\u27s Disease were forced to relocate there, suffering from human rights violations and labor exploitation. Isolation and the management of the patients by suppression and control were justified with the logic of modern values of sanitization supported by the colonial rule. Stigma has remained even after the liberation from the colonial power. Continuously recognized by people as an isolated, remote island with a significant concentration of patients with Hansen’s Disease, Sorokdo still is being poorly preserved and overlooked by the public and the government. Based on a literature review and field research, this article illustrates how stigmatized landscapes remain in the hospital, detention/testing rooms, the Japanese Shinto shrine, and Central Park, among others. This article points out the necessity to preserve the landscape so that Sorokdo can be used as a space to educate and reflect on history. The suppression of the patients and workers on this island also should be illuminated. This article further emphasizes that social consensus is required regarding how Sorokdo can be carefully managed as a place that reflects its traumatized colonial history

The value of chest CT for prediction of breast tumor size: comparison with pathology measurement

BACKGROUND: Little information is available on the use of chest computed tomography (CT) to predict breast tumor size in breast cancer, despite the fact that chest CT examinations are being increasingly used. The purpose of this study was to evaluate the value of chest CT for predicting breast tumor size using pathology measurements as reference standards. METHODS: Tumor sizes (defined as greatest diameter) were retrospectively measured on the preoperative chest CT images of 285 patients with surgically proven unifocal, invasive breast carcinoma. Greatest tumor diameters as determined by chest CT and pathologic examinations were compared by linear regression and Spearman’s rho correlation analysis. Concordance between CT and pathology results was defined as a diameter difference of <5 mm. Subgroup analyses were also performed with respect to tumor size (<20 mm or ≥20 mm) and histological subtype (invasive ductal carcinoma(IDC) or non-IDC). RESULTS: CT and pathology measured diameters were found to be linearly related (size at pathology = 1.086 × CT determined tumor size - 1.141; Spearman’s rho correlation coefficient = 0.84, P<0.001). Most tumors (n = 228, 80.0%) were concordant by chest CT and pathology, but 36 tumors (12.7%) were underestimated by CT (average underestimation, 11 mm; range, 6–36 mm) and 21 tumors (7.4%) were overestimated (average overestimation by CT, 10 mm; range, 6–19 mm). The concordance rate between the two sets of measurements was greater for tumor of <20 mm and for IDC (P<0.001 and P = 0.011, respectively). CONCLUSIONS: Tumor size by chest CT is well correlated with pathology determined tumor size in breast cancer patients, and the diameters of the majority of tumors by chest CT and pathology differed by <5 mm. In addition, the concordance rate was higher for breast tumors of <20 mm and for tumors of the IDC histologic subtype

Carrier frequency and incidence of alpha-mannosidosis: population database-based study—focus on the East Asian and Korean population

Background: Alpha-mannosidosis caused by mutations in the MAN2B1 gene is a rare genetic disorder characterized by physical abnormalities and intellectual disabilities. The objective of this study was to analyze the carrier frequency and estimated incidence of alpha-mannosidosis in East Asian populations, as limited data exists on its incidence in this group.Methods: In this study, a total of 125,748 exomes from the gnomAD database was analyzed. Additionally, 5,305 data from the KOVA and 1,722 data from the KRGDB, both representing Korean populations, were included.Results: The global carrier frequency of alpha-mannosidosis in gnomAD was 0.23%; the highest carrier frequency was observed in the Finnish at 0.49%, and East Asians had the second highest carrier frequency at 0.30%. Globally, the approximate incidence of alpha-mannosidosis was calculated at 1 in 784,535, l in 166,801 Europeans (Finnish), and l in 431,689 East Asians. By integrating the data from the 8,936 Koreans in gnomAD Korean, KOVA and KRGDB, the carrier frequency of alpha-mannosidosis in the Korean population was 0.04% and estimated incidence was 1 in 19,963,024.Conclusion: This study is the first to investigate the carrier frequencies of alpha-mannosidosis in East Asians and Koreans, including specific subpopulations, utilizing gnomAD and the Korean genomic database. The variant spectrum of MAN2B1 genes in East Asians showed significant differences compared to other ethnic groups. Our data provide valuable reference information for future investigations into alpha-mannosidosis, aiding in understanding the genetic diversity and specific variants associated with the condition in East Asian populations

Differential effect of corn oil-based low trans structured fat on the plasma and hepatic lipid profile in an atherogenic mouse model: comparison to hydrogenated trans fat

<p>Abstract</p> <p>Background</p> <p><it>Trans </it>fat are not desirable in many aspects on health maintenance. Low <it>trans </it>structured fats have been reported to be relatively more safe than <it>trans </it>fats.</p> <p>Methods</p> <p>We examined the effects of low <it>trans </it>structured fat from corn oil (LC), compared with high <it>trans </it>fat shortening, on cholesterol and fatty acid metabolism in apo E deficient mice which is an atherogenic animal model. The animals were fed a high <it>trans </it>fat (10% fat: commercial shortening (CS)) or a low <it>trans </it>fat (LC) diet for 12 weeks.</p> <p>Results</p> <p>LC decreased apo B and hepatic cholesterol and triglyceride concentration compared to the CS group but significantly increased plasma total cholesterol and triglyceride concentration and fecal lipids with a simultaneous increase in HDL-cholesterol level, apo A-I, and the ratio of HDL-cholesterol to total cholesterol (HTR). Reduction of hepatic lipid levels by inclusion of LC intake was observed alongside modulation of hepatic enzyme activities related to cholesterol esterification, fatty acid metabolism and fecal lipids level compared to the CS group. The differential effects of LC intake on the plasma and hepatic lipid profile seemed to be partly due to the fatty acid composition of LC which contains higher MUFA, PUFA and SFA content as well as lower content of <it>trans </it>fatty acids compared to CS.</p> <p>Conclusions</p> <p>We suggest that LC may exert a dual effect on plasma and hepatic lipid metabolism in an atherogenic animal model. Accordingly, LC, supplemented at 10% in diet, had an anti-atherogenic effect on these <it>apo E</it>^{<it>-/- </it>}mice, and increased fecal lipids, decreased hepatic steatosis, but elevated plasma lipids. Further studies are needed to verify the exact mode of action regarding the complex physiological changes and alteration in lipid metabolism caused by LC.</p
