The efficacy of CALL glossing on EFL learners' idiom learning.

The aim of this research is to investigate which CALL glossing modes (text only, text plus audio, and text plus video clips) are effective for learners' idiom acquisition. Ninety-nine intermediate-level first-year students from a university in China were divided into three groups. In order to determine if CALL glossing had any effect on students' idiom learning, pre- and post-idiom tests were administered. In addition, all the participants completed a questionnaire and five participants from each group completed face-to-face interviews to understand learners' perceptions of different CALL glosses. The results indicated that all three glossing modes promoted idiom acquisition; specifically, text with video glossing mode was more effective than text plus audio glosses and text only glossing mode. These results offer pedagogical implications for idiom teaching and learning, and also provide valuable insights for education in the future.

Teaching EFLLs Listening Subskills With a Speaking-Listening Model in a Computer-Mediated Communication Setting.

The purpose of this study is to explore the impact of teaching subskills, namely micro- and macro-skills, with a speaking-listening model on the improvement of listening competence. The research included 112 Chinese tertiary students with intermediate English proficiency who were recruited from around the country. Before attending a listening class, the experimental group engaged in oral practice of the subskills, while the control one engaged in conventional listening-oriented preparation before attending a listening class. A randomized controlled trial (RCT), as well as a questionnaire, were used to assess the listening skills. Following the results of the test analysis, we concluded that practicing listening subskills, first verbally and subsequently audibly, had a substantial impact on the development of listening competence. This efficiency was particularly evident when it came to growing discourse and pragmatical listening skills, rather than developing grammatical and sociolinguistic competence. The results of the questionnaire indicated that there was minimal difference between the two groups in terms of listening strategic competence. Our findings were confirmed by coding the interview data, which revealed that tertiary students' self-agency and class participation had increased. The findings indicate that teaching tertiary students listening with speaking before listening in a computer-mediated communication (CMC) setting has an uneven influence on their development of listening skills.

Multimedia Gloss Presentation: Learners' Preference and the Effects on EFL Vocabulary Learning and Reading Comprehension.

Drawing on Moreno's cognitive-affective theory of learning with media, this research aims to investigate the effectiveness of different multimedia glosses on learners' vocabulary acquisition and reading comprehension in a CALL environment. A total of 160 university students who learnt English as a foreign language (EFL) in four classes participated in the study and were exposed to one of the four conditions: (a) L2 definition only, (b) L2 definition coupled with audio, (c) L2 definition plus video, and (d) L2 definition with picture. Participants were asked to read eight hypermediated reading texts. Reading comprehension as well as vocabulary acquisition were measured using a pretest-posttest design. The results show first that all these four conditions led to students' vocabulary gains. More specifically, participants who had access to L2 definition plus picture and plus videos achieved significantly higher scores than the other two groups, L2 definition coupled with audio and L2 definition only. Concerning reading comprehension, all multimedia glossing presentation led to better reading comprehension, but no differences were found among all the glossing groups. The questionnaire and interview data indicate that students preferred L2 definition coupled with video and picture glosses, followed by audio and L2 definition only. The results reflect that multimedia glossing presentation creates a different effect on students' vocabulary acquisition and reading comprehension, respectively. They also provide pedagogical implications for learning in times of COVID-19.

Neosensitization to Multiple Drugs Following Valproate-Induced Drug Reaction with Eosinophilia and Systemic Symptoms Syndrome.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is associated with severe skin eruptions, fever, hematological abnormalities, and multi-organ involvement. Although aromatic anticonvulsant drugs have been frequently associated with the manifestation of DRESS syndrome, its induction following treatment with nonaromatic anticonvulsants, such as valproate, has rarely been reported. Moreover, there are limited data regarding the development of neosensitization related to chemically unrelated drugs following an episode of DRESS syndrome. Here, a case of neosensitization to multiple drugs is described. The present case report describes a female patient who experienced neosensitization to amoxicillin, olanzapine, and quetiapine following the manifestation of DRESS syndrome induced by valproate.

Prevalence of distorted body image in young Koreans and its association with age, sex, body weight status, and disordered eating behaviors.

PURPOSE: To define the prevalence of distorted body image in 10-24-year-old Koreans and determine its relationship with sex, age, body weight status, and disordered eating behaviors. METHODS: A total of 3,227 young Koreans were recruited from elementary, middle, and high schools, as well as from universities. The participants completed a self-reported questionnaire on body image, eating behaviors (Eating Attitude Test-26), and body weight status. RESULTS: The prevalence of a distorted body image in males was 49.7% and that in females was 51.2%. Distorted body image was more frequent in adolescents (age, 10-17 years) than in young adults (age, 18-24 years). The highest prevalence (55.3%) was reported in female elementary school students (age, 10-12 years). Distorted body image was associated with disordered eating behaviors and abnormal body weight status. CONCLUSION: These results suggest that distorted body image is a public health problem, given its high frequency in young Koreans, and that it is associated with abnormal body weight status and disordered eating behaviors.

The Relationship between Cognitive Decline and Psychopathology in Patients with Schizophrenia and Bipolar Disorder.

OBJECTIVE: The primary goals of the present study were to assess intellectual function in participants with schizophrenia or bipolar disorder (BD) and to investigate the relationships between cognitive decline and the severity of each type of psychopathology. METHODS: The present study included 51 patients with schizophrenia and 42 with BD who were recruited from the psychiatry outpatient clinic of Jeju University Hospital between March 2011 and March 2014. The Korean Wechsler Adult Intelligence Scale (K-WAIS) was administered to each of the 93 participants, and they were categorized into two groups based on their current intelligence quotient (IQ) and their estimated premorbid IQ: severely impaired group (SIG) and mildly impaired group (MIG). The Minnesota Multiple Personality Inventory (MMPI) and the Brief Psychiatric Rating Scale (BPRS) were used to assess psychopathology. RESULTS: The SIG schizophrenia participants exhibited significantly higher scores on the frequent (F) and schizophrenia (Sc) subscales of the MMPI, but significantly lower scores on the correction (K) and psychopathic deviate (Pd) subscales compared with the MIG schizophrenia participants. Furthermore, the BPRS scores were significantly higher in the SIG schizophrenia participants relative to the MIG schizophrenia participants. The SIG BD participants had significantly higher F, masculinity-femininity (Mf), paranoia (Pa), and Sc but significantly lower Pd scores compared with the MIG BD participants. CONCLUSIONS: The present findings revealed a significant discrepancy between the estimated premorbid levels of cognitive function and current cognitive function in participants with schizophrenia or BD. Moreover, this discrepancy was correlated with severity of psychopathology in both groups.

The prevalence of bipolar spectrum disorder in elderly patients with recurrent depression.

PURPOSE: Despite a growing body of knowledge on bipolar spectrum disorder (BSD), relatively little is known about the clinical characteristics of BSD in elderly people. We investigated the prevalence of BSD in elderly patients with recurrent depression. PATIENTS AND METHODS: A total of 65 elderly outpatients (≥60 years of age) who met the Diagnostic and Statistical Manual of Mental Disorders IV criteria for recurrent major depressive disorder participated in the study. BSD was diagnosed according to the criteria developed by Ghaemi et al and the Mood Disorder Questionnaire (MDQ) was used to assess bipolarity. RESULTS: Of 65 subjects, eleven (16.9%) and 54 (83.1%) were diagnosed with BSD and unipolar depression, respectively. A total of 32.3% (n=22) had a positive screen for bipolar disorder, and we found a significant association between the BSD criteria and the criteria for a positive MDQ (P<0.001). Patients with BSD had a longer duration of illness (P=0.040) and more prior depressive episodes (P<0.001) than did those with unipolar depression. The BSD criteria of first-degree relative with bipolar disorder (P=0.030), antidepressant-induced hypomania (P=0.034), hyperthymic personality (P=0.001), and atypical depression (P=0.030) were highly associated with MDQ-positive patients. CONCLUSION: Our results indicate that many depressed elderly patients have bipolar-related illness; moreover, some features of the depression are associated with bipolarity.

Comparison of cerebrospinal fluid biomarkers between idiopathic normal pressure hydrocephalus and subarachnoid hemorrhage-induced chronic hydrocephalus: a pilot study.

BACKGROUND: We examined the cerebrospinal fluid (CSF) markers of subarachnoid hemorrhage (SAH)-induced and idiopathic normal pressure hydrocephalus (INPH) to investigate the pathophysiology and mechanism of communicating hydrocephalus compared to obstructive hydrocephalus. MATERIAL/METHODS: We obtained CSF samples from 8 INPH, 10 SAH-induced hydrocephalus, and 6 unmatched patients with non-hemorrhagic obstructive hydrocephalus during their ventriculoperitoneal shunt operations. Transforming growth factor (TGF)-ß1, tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), and total tau in the CSF were analyzed via enzyme-linked immunosorbent assay. RESULTS: The mean VEGF levels in the CSF of patients with SAH-induced hydrocephalus, INPH, and obstructive hydrocephalus were 239 ± 131, 239 ± 75, and 163 ± 122 pg/mL, respectively. The total tau concentrations in the CSF of the groups were 1139 ± 1900, 325 ± 325, and 1550 ± 2886 pg/mL, respectively. TNF-α values were 114 ± 34, 134 ± 38, and 55 ± 16 pg/mL, respectively. TGF-ß1 values were 953 ± 430, 869 ± 447, and 136 ± 63 pg/mL, respectively. A significant difference in TNF-α and TGF-ß1 levels was observed only between SAH-induced and chronic obstructive hydrocephalus, and between INPH and chronic obstructive hydrocephalus (p<0.01). CONCLUSIONS: No significant differences in the 4 CSF biomarker levels were observed between INPH and SAH-induced hydrocephalus, whereas CSF TNF-α and TGF-ß1 levels were increased compared to those in patients with chronic obstructive hydrocephalus. Post-SAH hydrocephalus and INPH are probably more destructive to neural tissues, and then stimulate the inflammatory reaction and healing process, compared with obstructive hydrocephalus.

Prevalence of dementia and its correlates among participants in the National Early Dementia Detection Program during 2006-2009.

OBJECTIVE: To investigate the prevalence of dementia and its correlates among people with poor socioeconomic status, poor social support systems, and poor performance on the Korean version of the Mini-Mental Status Exam (MMSE-KC). METHODS: We used 2006-2009 data of the National Early Dementia Detection Program (NEDDP) conducted on Jeju Island. This program included all residents >65 years old who were receiving financial assistance. We examined those who performed poorly (standard deviation from the norm of <-1.5) on the MMSE-KC administered as part of the NEDDP, using age-, gender-, and education-adjusted norms for Korean elders. A total of 1708 people were included in this category. RESULTS: The prevalence of dementia in this group was 20.5%. Multivariate logistic regression analysis revealed that the following factors were statistically significantly associated with dementia: age of 80 or older, no education, nursing home residence, and depression. CONCLUSION: The prevalence of dementia is very high among those with lower MMSE-KC scores, and significant correlates include older age, no education, living in a nursing home, and depression. Enhancing lifetime education to improve individuals' cognitive reserves by providing intellectually challenging activities, encouraging living at home rather than in a nursing home, and preventing and treating depression in its early phase could reduce the prevalence of dementia in this population.

The influence of subcortical ischemic lesions on cognitive function and quality of life in late life depression.

OBJECTIVES: Subcortical ischemic lesions (SIL) are known to contribute to the pathogenesis of late life depression. The present study examined the influence of SIL on cognitive function and quality of life in elderly Koreans with major depressive disorder (MDD). METHODS: MDD patients (n=86) underwent CT scans and were classified as having SIL if they had a score of 2 or above on age-related white matter changes (ARWMC) scale. Demographic data, psychiatric, medical history, neuropsychological test, quality of life, and depressive symptomatology were compared between MDD patients with and without SIL. RESULTS: SIL with grade 2 or above were found in deep white matter of 22 (25.6%) depressed patients and in basal ganglia of 9 (10.5%) depressed patients. Depressed patients with deep white matter lesions showed poor performance on MMSE-KC and decreased quality of life, particularly in physical function and physical role limitation, as compared to depressed patients without deep white matter lesions. CONCLUSION: These data support that SIL may cause general cognitive dysfunction and poor physical health. More attention should be paid to detection and management of SIL in late life depression in clinical setting.

Effects of obesity and obesity-induced stress on depressive symptoms in Korean elementary school children.

BACKGROUND: Obesity is becoming prevalent in Korean children. Because body image is becoming increasingly important, it is likely that obesity-induced stress has a significant effect on childhood depression. AIMS: To examine the correlation between obesity-induced stress and depressive symptoms in Korean elementary school students. METHODS: The study participants were 2,305 elementary school children and their parents in the districts of Jeju-si, Seogwipo-si, Namjeju-gun and Bukjeju-gun on Jeju Island, Korea, who completed questionnaires involving demographic information, an obesity-induced stress scale and the Korean form of Kovacs' Children's Depression Inventory (CDI) from September to December 2006. RESULTS: After controlling for significant independent variables that are wellknown correlates of depressive symptoms in children (e.g. age, gender, residence, family monthly income, obesity status of both parents, family history of chronic illness, and time spent with mother), obesity-induced stress had an odds ratio of 1.128 (95% CI 1.111-1.146). CONCLUSIONS: Reducing the prevalence of depressive symptoms in elementary school children in Jeju Island will require special attention, particularly the development of coping strategies to resolve obesity-induced stress in various areas including school, family and society.

Prevalence and Correlates of Depressive Symptoms among North Korean Defectors Living in South Korea for More than One Year.

OBJECTIVE: This study examined the prevalence and correlates of depressive symptoms in North Korean defectors who have been living in South Korea for more than one year. METHODS: We used questionnaires developed by the authors to collect sociodemographic data in addition to the Center for Epidemiologic Studies Depression Scale (CES-D), the Psychosocial Well-being Index to measure stress, and a social support scale. A total of 367 subjects were included in this study. RESULTS: The results showed that 30.5% of the men and 34.7% of the women reported depressive symptoms, and 33.1% of the men and 36.1% of the women exhibited signs of severe distress. Correlates of depressive symptoms were lack of occupation [odds ratio (OR)=2.198, 95% confidence interval (CI), 1.247-3.873], having escaped without family (OR=1.725, 95% CI, 1.006-2.959), and a poor subjective sense of health status (OR=3.111, 95% CI, 1.591-6.085). CONCLUSION: Continuing vocational training and career management, psychological support programs, and intensive physical health services are needed to improve the mental health of this population.

Caregiver burden among caregivers of Koreans with dementia.

BACKGROUND: Most studies on caregiver burden have been conducted in Western countries, while few studies on the correlates of caregiver burden have been performed in Korea. OBJECTIVE: To suggest better policies for the care of dementia patients by using a nationwide database to identify factors that affect caregiver burden in Korea. METHODS: The database of the Korean National Health Insurance (KNHI) and National Medical Aid (NMA) programs, which covers all Koreans, was used. A sample of 609 dementia patients and their caregivers was selected from a total of 85,281 dementia patients in 2004 and interviewed to evaluate the total cost of care and caregiver burden. Stepwise multiple linear regression analysis was then performed to identify significant independent predictors of caregiver burden. RESULTS: Among caregiver-related factors, caregiver burden was higher in those who were female, had a history of home care during the previous year, and had less education. Among patient-related factors, poor ADL/IADL function was significant. The most interesting result was that subjective sense of socioeconomic status (good/fair/poor) was a stronger predictor of caregiver outcome than actual economic costs. CONCLUSION: The results of this study suggest that interventions to assist patients with dementia should focus on female caregivers, especially those considered likely to be suffering from an economic burden. Interventions should also aim to improve the ADL and IADL capacities of patients.

Depressive symptoms in elementary school children in Jeju Island, Korea: prevalence and correlates.

We investigated the prevalence and correlates of depressive symptoms in elementary school children in Jeju Island, Korea. The study participants were 2305 children enrolled in elementary schools in Jeju-si, Seogwipo-si, Namjeju-gun, and Bukjeju-gun and their parents who completed questionnaires about sociodemographics, health habits, family relationship information, and the Korean form of the Kovac's children's depression inventory (CDI) in September to December 2005. Multiple logistic regression showed that higher age (OR = 1.259, 95% CI 1.098-1.445), short time spent developing a relationship with the mother (OR = 2.770, 95% CI 1.280-5.944), and a low level of body image satisfaction (OR = 3.397, 95% CI 1.823-6.330) were correlates of depressive symptoms in children. Our results suggest that the following are essential to prevent depressive symptoms in elementary school children in Jeju, Korea: advanced education and social activity programs at home, in school, and in the community to help children have a positive self-image, and much time spent building a relationship with the mother.

Prevalence of depression and correlates of depressive symptoms for residents in the urban part of Jeju Island, Korea.

AIMS: This study examined the prevalence of depression and depressive symptoms, and the correlates of depressive symptoms, and proposes some methods for reducing risk of depression in residents of the urban part of Jeju Island in Korea. METHODS: In all, 1050 residents were selected using multiphasic cluster sampling to represent each district. Of the 981 respondents, 413 were men and 568 were women. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to evaluate depression (CES-D score over 25) and depressive symptoms (CES-D score over 21). Multiple logistic regression analysis was performed for comparisons. RESULTS: The prevalence of depression in males and females was comparable, at 9.47 and 11.36%, respectively. The prevalence of depressive symptoms in men was 15.01%, while in women the level rose to 18.37%. Those with high self-assessed level of stress scores were significantly more likely to have depressive symptoms than those with low self-assessed level of stress scores (odds ratio (OR) = 5.73 (95% confidence interval (95% CI), 1.29-25.36)). Residents at high risk of problem drinking (CAGE score over 3) were significantly more likely to have depressive symptoms than those with a CAGE score under 1 (OR = 3.43 95% CI, 1.77-6.66). Respondents who slept poorly had more depressive symptoms than respondents who slept well (OR = 2.11 95% CI, 1.37-3.23). Females were significantly more likely to have more depressive symptoms than males (OR = 1.70 95% CI, 1.08-2.68). CONCLUSIONS: The prevalence of depression and depressive symptoms in urban Jeju Island is similar to that in a nation-wide sample. By providing intensive mental health services to those who have high stress levels, problem drinking, and poor health behavior, early detection of depressive symptoms in the community will be important for improving general health status.

[A study on regional differentials in death caused by suicide in South Korea].

PURPOSE: The purpose of this study was to compare suicide mortality by region in South Korea. METHOD: Suicide mortality differentials were calculated for several mortality indicators by geographical regions from raw data of the cause of death from KNSO. RESULTS: The results are as follows; the Crude suicide death rate was 22.63 per 100,000. The highest was in Kangwon showing 37.84% whereas, Chungnam, and Jeonbuk followed after. Suicide was 4.4% of all causes of death, but Inchon and Ulsan showed a higher proportion. The male suicide death rate was 31.12 per 100,000 and females 14.09. The ratio of gender suicide mortality was 2.21, per 100,000 and was the highest in Jeju. For age-specific suicide death rates, the rate increased as age advanced, showing 2.33 per 100,000 in 0-19 years, 18.68 in 20-39, 30.48 in 40-59,63.33 in 60 years and over. In Ulsan, Kangwon, and Inchon, age-specific suicide death rates of the 60 and over age group were higher than other regions, Daegu, Busan, and Kangwon showed a higher age-specific suicide mortality of the 40-59 age group, and Kangwon, Jeonnam, and Chungnam had a higher age-specific suicide mortality of the 20-39 age group. CONCLUSIONS: Suicide mortality differed by region. These results can be used for a regional health care plan and planning for suicide prevention by regions.

Suicide risk in relation to social class: a national register-based study of adult suicides in Korea, 1999-2001.

BACKGROUND: Few controlled studies have examined social class as a risk factor for suicide in Korea. AIM: The objective of the present study was to investigate the effects of social class on suicide risk in Korea. METHODS: A case-control design was constructed from cause-of-death statistics for the period 1999 to 2001, in Korea, as published by the Korean National Statistical Office. The cases were defined as people aged between 20 and 64 who died by suicide, while the controls were defined as those who died of natural causes in the same age groups. RESULTS AND CONCLUSIONS: The proportions and odds ratios for suicide were higher in young people than in elderly people, and higher for divorced subjects than for cohabitants. They were also higher for residents of rural areas, as opposed to residents of Seoul and other metropolitan areas, and for people in social classes III and IV, than they were for those in social class I. To control the variables that influence risk of suicide, such as age, marital status and area of residence, we used multiple logistic regression. Compared with class I, risk of suicide was higher in social classes III and IV, in both sexes. The principal conclusion of this study is that, regardless of sex, lower social class constitutes a high risk for suicide in Korea, even after controlling for variables such as age, marital status and area of residence. We conclude that a well-controlled and balanced social welfare system could reduce suicide risk, especially among people in lower social class.
