The purpose of this study was to provide basic data to improve college food service satisfaction with sanitary, environment and service by comparing 2 contract-managed and 2 self-operated college food services in Daejeon and Chungnam area. According to the results, sanitation and environment satisfaction degrees of contract-managed college food services were higher than those of self-operated food services. The satisfaction degrees with service were also higher in contract-managed food services than self-operated food services except the category of quick food delivery. In all categories comprising the food service satisfaction, the satisfaction degrees were lower in female students than in male students. There were more negative self-perceived clinical symptoms in female students than male students. The higher the negative self-perceived clinical symptoms scores were, the lower the satisfaction degrees with food service were, which suggests that the health state of students was one of the factors that influenced college food service satisfaction. There was no difference between contract-managed and self-operated food services in terms of satisfaction with overall food taste and overall satisfaction degree. The average satisfaction degree for the contract-managed food services in terms of price relative to food quality was lower than that for self-operated food services. According to stepwise multiple regression analysis, 'overall food taste', 'price relative to quality', 'kindness of employees', 'coping with proposed opinions' and 'quickness of food delivery' in decreasing order, were the most relatively important attributes for overall satisfaction. There should be further studies on important management factors to improve satisfaction with sanitary, environment and service by self-operated college food service.

College foodservice (FS) demands highly-developed operation technique which can provide adequate nutrients to their students, as well as to guide better eating habits and to meet students' various desires. The purpose of this study was to provide basic data to improve college FS satisfaction with food items by comparing 2 contract-managed and 2 self-operated college FS in Daejeon and Chungnam area. According to the results, 59.1% of students frequently (over 3 times per week) took meals at college cafeteria and the main reason for using college cafeteria was the low-price of meal, although the students' satisfaction degree with price of meal was lower in contract-managed FS than in self-operated FS. There were no differences in the food satisfaction degrees with overall appraisal of food items between 2 operating systems of college FS, but the satisfaction degrees with all food items were high in male as compared with female. The higher the negative self-perceived clinical symptoms scores, the lower the satisfaction with foods, which suggests that the health state of students was one of the factors that influenced college FS satisfaction. According to stepwise multiple regression analysis, 'taste of boiled rice', 'overall appraisal of boiled rice', 'overall appraisal of soup', and 'variety of side dish', in decreasing order, were the most relatively important attributes for overall customer satisfaction with food taste of college FS. Finally, there should be further studies on important management factors to improve college FS satisfaction according to 2 operating systems.

A 26-year-old man with a one-year history of asthma and sinusitis presented with bilateral pleural effusions, patch basilar infiltrates on a chest x-ray and a pericardial effusion on an echocardiogram. The peripheral blood showed marked eosinophilia. An obstructive pattern was also observed during the pulmonary fuction test, which was responsive to bronchodilator inhalation. Nerve conduction studies showed right sural neuropathy. Thoracentesis yielded an acidotic exudative effusion with low glucose, low C3 and eosinophilia. An open lung biopsy revealed an eosinophilic interstitial pneumonitis associated with a necrotizing eosinophilic vasculitis, and granulomatous inflammation foci. In the literature, pleural effusions were reported in 29 percent of Churg-Strauss patients, but the number of effusions was low and their characteristics have not been well described. This report describes the characteristic findings of pleural fluid and its histologic features in a case of classical Churg-Strauss syndrome.

Cellular oncogenes are expressed as an intrinsic part of the transformed or neoplastic phenotype. More than 60 of the known cellular oncogenes play a specific role in normal cellular development and differentiation. To examine the correlation between ras oncogene expression and the development of cervical cancer, this study investigated the reactivity of cervical intraepithelial neoplasia(CIN) and carcinoma of the uterine cervix by using anti-ras P21 mouse monoclonal antibody. The expression of ras oncogene significantly increased with the grade of malignancy from 11% in severe dysplasia, 30% in carcinoma in situ, 43% in microinvasive carcinoma, to 53% in invasive cancer. The expression of ras oncogene was not correlated with histologic type, tumor size, and nodal status of cervical cancer. It was concluded that expression of ras oncogene is related to early phase of carcinogenesis and tumor invasion of carcinoma of the uterine cervix.

Investigations into the development of new therapeutic agents for lung inflammatory disorders have led to the discovery of plant-based alternatives. The rhizomes of Anemarrhena asphodeloides have a long history of use against lung inflammatory disorders in traditional herbal medicine. However, the therapeutic potential of this plant material in animal models of lung inflammation has yet to be evaluated. In the present study, we prepared the alcoholic extract and derived the saponin-enriched fraction from the rhizomes of A. asphodeloides and isolated timosaponin A-III, a major constituent. Lung inflammation was induced by intranasal administration of lipopolysaccharide (LPS) to mice, representing an animal model of acute lung injury (ALI). The alcoholic extract (50–200 mg/kg) inhibited the development of ALI. Especially, the oral administration of the saponin-enriched fraction (10–50 mg/kg) potently inhibited the lung inflammatory index. It reduced the total number of inflammatory cells in the bronchoalveolar lavage fluid (BALF). Histological changes in alveolar wall thickness and the number of infiltrated cells of the lung tissue also indicated that the saponin-enriched fraction strongly inhibited lung inflammation. Most importantly, the oral administration of timosaponin A-III at 25–50 mg/kg significantly inhibited the inflammatory markers observed in LPS-induced ALI mice. All these findings, for the first time, provide evidence supporting the effectiveness of A. asphodeloides and its major constituent, timosaponin A-III, in alleviating lung inflammation.

PURPOSE: We applied Learning Vector Quantization (LVQ) in the analysis of data from Kawasaki disease patients with coronary artery aneurysm in an attempt to achieve accurate predictions of outcome for individual patients. METHODS: One hundred and seventy-five patients with Kawasaki disease were recruited. First, data of 75 patients (of which 60 patients had no aneurysm and 15 patients had aneurysm) were trained using the network. The data contained age, sex, white blood cell count, platelet count, CRP, and serum albumin of each individual. Then, data of another 100 patients (of which 83 patients had no aneurysm and 17 patients had aneurysm) were integrated into the previously trained LVQ neural network. After the analysis was completed, the sensitivity, specificity, positive predictive value, and negative predictive value were compared between the LVQ neural network and Harada risk index. RESULTS: Out of 100 patients, it was evaluated that 21 patients had coronary aneurysm and 79 patients did not. Among the 21 patients, 15 patients actually did have the disease, while 77 out of 79 patient actually did not have coronary aneurysm. The sensitivity, specificity, positive predictive value and negative predictive value were 88.2, 92.7, 71.4 and 97.4%, respectively. The values by the conventional Harada scoring were 52.9, 92.7, 60.7 and 91.7%, respectively, and contrasting the values above. CONCLUSOIN: LVQ neural network can classify and predict patients who, in the future, will have coronary artery aneurysm. This method is superior than the conventional methods in predicting aneurysm.

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

A 49-year-old man with an uncorrected visual acuity (UCVA) of 20 / 1000, a best spectacle-corrected visual acuity (BSCVA) of 20 / 400, keratometric readings of K1 = 59.88 x 82degrees / K2 = 45.88 x 172degrees, and an inferior steepening that was consistent with keratoconus in his left eye was treated with clear-cornea phacoemulsification and an intraocular lens (IOL) implantation after insertion of keraring intrastromal corneal ring segments for severe keratoconus and cataract. An asymmetrical pair of kerarings was implanted with the assistance of a femtosecond laser in September 2008; the one segment was 250 microm and the other was 150 microm and both were placed at 70degrees. Three months after the kerarings were implanted, clear-cornea phacoemulsification and IOL implantation were performed on the left eye. After surgery, both the UCVA and the BSCVA of the left eye improved by eight lines. Postoperative central keratometry showed a decrease of 7.35 diopters in the left eye. Both the postoperative refraction (-0.75 -0.75 x 60degrees) and the keratometric reading (K1 = 50.05 x 93degrees / K2 = 48.83 x 3degrees) remained stable one month following the procedures. Thus, the sequential order of intrastromal corneal rings implantation and cataract surgery can be considered as a treatment option in patients with severe keratoconus and cataract.
