The present study examined cortical cerebral microinfarcts (CMIs) on a 3T magnetic resonance imaging and investigated the impact of CMIs on the comprehensive functional outcomes during the post-stroke rehabilitation period. Patients with acute phase of firstever ischemic stroke were retrospectively recruited (n = 62) and divided into 2 groups with and without CMIs. Clinical parameters including age, sex, stroke lesion laterality, location, the National Institutes of Health Stroke Scale score, as well as history of hypertension, dyslipidemia, diabetes mellitus, and smoking were obtained. Functional outcomes were assessed twice at baseline and one month later with the Korean version of the MiniMental State Examination, the Berg balance scale (BBS), and the functional independence measure. Partial correlation and multiple linear regression analyses were used to examine the relationship between the presence of CMIs and the change in functional outcomes. At least one CMI was reported in 27 patients, who were older (p = 0.043). The presence of CMIs was significantly associated with functional impairment in all 3 functional outcomes, after controlling for confounding factors (p < 0.05). CMIs might contribute to poor functional outcomes during the post-stroke rehabilitation period. These results suggest that CMIs should be considered when establishing rehabilitation treatment strategies or making a prognosis.

Objective:
Patients who have suffered a stroke may experience dysphagia, which could raise the risk of aspiration pneumonia and death. This is also a complication prevalent in older adults with various comorbidities. This study aimed at investigating the association between head lifting strength and dysphagia, particularly in each of the two phases of dysphagia, namely the oral and the pharyngeal phase, in stroke patients.
Methods:
We prospectively recruited 64 patients within six months of their first-ever stroke. Head lifting strength, handgrip strength, and calf circumference were measured. The severity of dysphagia was evaluated using the videofluoroscopic dysphagia scale (VDS). Partial correlation and multiple linear regression analyses were applied to examine the association between head lifting strength and dysphagia.
Results:
The subjects were comprised of 31 men and 33 women with a mean age of 63 years. The median National Institute of Health Stroke Scale (NIHSS) score was 5.5 (interquartile range 4.0-8.0). Based on the penetration-aspiration scale, 46 participants had dysphagia without aspiration and 18 had dysphagia with aspiration. The head lifting strength in the non-aspiration group was higher compared with the aspiration group. The head lifting strength was significantly correlated with the VDS-pharyngeal phase (r=−0.715) and the penetration-aspiration scale (r=−0.662). In the multiple linear regression analysis, head lifting strength was independently associated with pharyngeal-phase dysphagia (P<0.001).
Conclusion
Head lifting strength is significantly associated with the severity of dysphagia in the pharyngeal phase.

PURPOSE: The purpose of this study is to investigate influence of cellular phone videos and games on dry eye syndrome in university students. METHODS: A randomized comparison group pre-post design is used. Sixty university students were randomly assigned to either a video or a game group. Frequencies of blinking, dry eye symptoms scores and amounts of tears were measured. Thirty subjects watched cellular phone video programmes and the other 30 subjects played cellular phone games for 61 minutes. In addition, frequencies of blinking were measured three times during treatment, once immediately after a treatment and twice at an interval of 20 minutes after subsequent treatments. RESULTS: Post-test scores of frequencies of blinking significantly decreased, dry eye symptoms scores including amounts of tears significantly increased greater than pre-test scores in both groups. But there were no significant differences between the groups. Frequencies of blinking were significantly different with respect to the time spent using cellular phone. In both groups, the lowest frequencies of blinking were shown after 40 minutes of cellular phone use. CONCLUSION: This study shows that using cellular phone has negative influence on dry eye syndrome and eyes require a resting period after cellular phone use over 40 minutes.

Sjogren's syndrome(SS) is an autoimmune disease characterized by inflammation induced chronic dysfunction of the exocrine glands. Neurologic manifestations occurs in 30% of patients. We report a 55-year-old woman with primary SS, who presented with subacute aseptic meningitis combined with an unnoticed polyneuropathy. SS was confirmed by dry eyes and Schirmer's test, salivary scintigraphy and serum autoantibodies. We suggest SS as a cause of subacute aseptic meningitis in an elderly female patient with dry eyes and mouth.

Objectives:
The aim of this study was to provide baseline data for the assessment of exposure to indium and to prevent adverse health effects among workers engaged in the electronics and related industries in Republic of Korea.
Methods:
Total (n = 369) and respirable (n = 384) indium concentrations were monitored using personal air sampling in workers at the following 19 workplaces: six sputtering target manufacturing companies, four manufacturing companies of panel displays, two companies engaged in cleaning of sputtering components, two companies dedicated to the cleaning of sputtering target, and five indium recycling companies.
Results:
The level of exposure to total indium ranged from 0.9 to 609.3 μg/m3 for the sputtering target companies; from 0.2 to 2,782.0 μg/m3 for the panel display companies and from 0.5 to 2,089.9 μg/m3 for the indium recycling companies. The level of exposure to respirable indium was in the range of 0.02 to 448.6 μg/m3 for the sputtering target companies; 0.01 to 419.5 μg/m3 for the panel display companies; and 0.5 to 436.3 μg/m3 for the indium recycling companies. The indium recycling companies had the most samples exceeding the exposure standard for indium, followed by sputtering target companies and panel display companies.
Conclusions
The main finding from this exposure assessment is that many workers who handle indium compounds in the electronics industry are exposed to indium levels that exceed the exposure standards for indium. Hence, it is necessary to continuously monitor the indium exposure of this workforce and take measures to reduce its exposure levels.

BACKGROUND: Right middle lobe syndrome (RMLS) is defined as transient or chronic and recurrent atelectasis of the right middle lobe. Although numerous conditions are associated with RMLS, there are very few recent reports in Korea. This study evaluated the causes of RMLS in a local tertiary hospitalover a period of 42 months. METHOD: Eighty-eight patients (M:F=64:22, mean age: 67.2+/-10.3 years), who had consistent chest radiography findings and underwent bronchoscopy in Gyeongsang University Hospital from January 2003 to July 2006, were enrolled in this study. The clinical characteristics and causes of RMLS in these patients were retrospectively reviewed. RESULTS: The most common symptoms fo RMLS were cough, dyspnea and sputum. Tuberculosis was the most common cause (endobronchial tuberculosis in 22 and pulmonary tuberculosis in 1) The other causes were bronchial stenosis by benign fibrotic changes in 22 cases (25%), anthracofibrosis in 13 cases (14.8%), pneumonia in 11 cases (12.5%), lung cancer in 10 cases (11.4%), mucus impaction in 3 cases (3.4%), bronchiectasis in 2 cases (2.3%) and no demonstrable causes in 7 cases (8%). The bronchoscopy findings were mucosal edema with hyperemic changes in 38 cases (43.2%), mucosal edema with anthracotic pigmentation in 16 cases (18.2%), mucus impaction in 13 cases (14.8%), fibrotic stenosis in 13 cases (14.8%), a mass like lesion in 8 cases (9.1%), exudative necrotic material in 4 cases (4.5%), narrowing as a result of extrinsic compression in 2 cases (2.3%) and no demonstrable abnormalities in 12 cases (13.6%). CONCLUSION: Right middle lobe syndrome was observed more frequently in patients over the age of 65. The causes were mainly benign diseases with endobronchial tuberculosis being the most common.

PURPOSE: To review the sonographic findings of various diseases showing architectural distortion depicted under mammography. MATERIALS AND METHODS: We collected and reviewed architectural distortions observed under mammography at our health institution between 1 March 2004, and 28 February 2007. We collected 23 cases of sonographically-detected mammographic architectural distortions that confirmed lesions after surgical resection. The sonographic findings of mammographic architectural distortion were analyzed by use of the BI-RADS lexicon for shape, margin, lesion boundary, echo pattern, posterior acoustic feature and orientation. RESULTS: There were variable diseases that showed architectural distortion depicted under mammography. Fibrocystic disease was the most common presentation (n = 6), followed by adenosis (n = 2), stromal fibrosis (n = 2), radial scar (n = 3), usual ductal hyperplasia (n = 1), atypical ductal hyperplasia (n = 1) and mild fibrosis with microcalcification (n = 1). Malignant lesions such as ductal carcinoma in situ (DCIS) (n = 2), lobular carcinoma in situ (LCIS) (n = 2), invasive ductal carcinoma (n = 2) and invasive lobular carcinoma (n = 1) were observed. As ovserved by sonography, shape was divided as irregular (n = 22) and round (n = 1). Margin was divided as circumscribed (n = 1), indistinct (n = 7), angular (n = 1), microlobulated (n = 1) and sipculated (n = 13). Lesion boundary was divided as abrupt interface (n = 11) and echogenic halo (n = 12). Echo pattern was divided as hypoechoic (n = 20), anechoic (n = 1), hyperechoic (n = 1) and isoechoic (n = 1). Posterior acoustic feature was divided as posterior acoustic feature (n = 7), posterior acoustic shadow (n = 15) and complex posterior acoustic feature (n = 1). Orientation was divided as parallel (n = 12) and not parallel (n = 11). There were no differential sonographic findings between benign and malignant lesions. CONCLUSION: This study presented various sonographic findings of mammographic architectural distortion and that it is difficult to differentiate between benign and malignant lesions depicted under sonography. Pathological confirmation is needed for mammographic architectural distortion.

OBJECTIVES: he purpose of this study was to examine psychosocial factors related to burnout of social welfare officers working in Jeonnam Province.METHODS: A total of 395 social welfare officers (male 99, female 296) working in 22 areas of Jeollanam-do province, were subjects of this study. We examined socio-demographic factors, using a self-reporting questionnaire. Subjects were asked to complete the Maslach Burnout Inventory-General Survey (MBI-GS), Center for Epidemiological Studies Depression Scale (CES-D), Perceived Stress Scale (PSS), and the Generalized Self-Efficacy Scale (GSS), to assess psychosocial factors affecting to burnout of social welfare officers.RESULTS: Among 395 subjects, 221 (55.9%) reported recent experiences of burnout. There was no significant difference in age between two groups, divided by burnout. Sex (p < 0.001), rank (p=0.003), working period (p=0.034), depression (p < 0.001) revealed differences between the burnout group and control group. Scores of PSS (p < 0.001) were higher, while the scores of GSS (p < 0.001) were lower in the burnout group, than control group. Multivariate logistic regression analysis revealed that female (OR 2.840, 95%CI 1.466–5.504, p=0.002), depressive high-risk group (OR 6.824, 95%CI 2.893–16.096, p < 0.001) PSS (OR 1.247, 95%CI 1.153–1.349, p < 0.001) and GSS (OR 0.950, 95%CI 0.930–0.971, p < 0.001), were significantly associated with burnout.CONCLUSION: We found that some factors, were associated with experienced burnout in social welfare officers. Depressive symptoms were the strongest associative factor, for burnout in public servants in charge of social welfare. Sex, stress and self-efficacy also correlated with burnout, and especially self-efficacy was a protecting factor.
