Objectives : This study of oral health problems was conducted to 311 students in Special Schools in order to inquire into the state of their oral health behaviors, to find out the main obstacles against dental services, to secure dental reasonable basis for oral health promotion. Methods : A questionnaire survey was conducted in the Special School of the 311 students in the area of the metropolitan Seoul. By means of Chi-squared test and Fisher's exact test, oral hygiene habits for each type of the subjects, the contents of dental care services, the prerequisites to improve oral health, were inquired. To evaluate the effects to the current oral health status of types of disability, 2-way ANOVA was practiced. Results : The handicapped with Visual impairment, mental retardation, multiplicity with disabilities, answered negatively in their own oral health status. 47.4% of the deaf can do brush for theirselves without the inconvenience, but in other types of disability they showed that they were helped by others. Subjects did not use the secondary oral hygiene necessaries because, except brain damage, almost of types of disability impeded the convenient use. 60 to 88.2 percent of the total respondents were the recent visitors to dental clinique within 1 year, and the most common motives of the visiting dentist, is a routine medical examination, their movements to the dentist in all types of disabilities, needed helps of others. Most of them received medical treatment at a private dentist, the handicapped preferred the private care and place(49.8%). Only in the case of the brain disorders, extremely much of the disabled answered that they were needed the preventive treatment, and the another cases of disability were largely needed the treatment of the decayed teeth. To improve the oral health of the people with disabilities, at the opening of the clinics and hospitals over a certain size, the mandatory medical facilities for the care of the disabled should be preceded and followed by the improvement of dental insurance system so as to reduce the burdens of the cost of dental care. Conclusions : The improvement of oral health policy for the disabled are needed inevitably: Development of secondary oral hygienic easy to use for the disabled, the building systems of medical dental hospital with the disabled facilities, by the improvement of the insurance system, the reduction of the burden of payments.

Purpose: To compare the safety and efficacy of first-line chemotherapy regimen with or without doxorubicin in treating patients with advanced soft tissue sarcoma (STS). Patients and Methods: We retrospectively analyzed a cohort of 56 patients histologically confirmed with STS who were treated at Jiangsu Cancer Hospital and Research Institute from July 2011 to June 2012.The basic element of first line chemotherapy contained epirubicin in group B and lacked epirubicin in group A. Response was assessed using RECIST criteria. The Kaplan-Meier method was used to estimate progress free survival (PFS). Results: According to RECIST criteria, patients in group treated by chemotherapy without epirubicin, the objective response (OR) ratio was 6.5 % (CR0%+PR6.5%). Disease control rate (DCR=CR+PR+SD) was 25.8% with a median follow-up of 14.6 months, including 2 patients achieving a partial response (PR 6.5%) and a stable response (SD 19.4%) in 6. In group B with epirubicin based regimens, no patient had complete response, PR (28 %) was observed in 7 and SD (24 %) in 6. DCR was observed in 13 patients (52%). By Fisher's exact test, the DCR difference between the two groups was statistically significant (p=0.046). In group A, median PFS was 3.0 months (95%CI:2.1-3.8), compared with 4.0 months (95% CI:3.03-4.97) in group B (p=0.0397 by log-rank test). Epirubicin based chemotherapy and ECOG performance status 0-1 were identified as favorable factors for progression in our cohort of patients. Differences of nonhematologic and hematologic toxicities were not statistically significant between the two groups, and the addition of epirobicin was not associated with cardiac toxicity (p=0.446). Conclusion: Our study demonstrates that epirubicin-based chemotherapy is effective and well tolerated, and is superior to chemotherapy without epirubicin regarding efficacy. Therefore it is recommended that epirubicin-based chemotherapy should be considered as first line for patients with advanced STS.

Purpose: In general, X-ray examinations are not recommended for radial head subluxation (pulled elbow) patients. The purpose of this study was to determine the frequency of X-ray examinations and to investigate the factors associated with the decision to perform an X-ray examination on a patient with a pulled elbow. Methods: Patients who visited the pediatric emergency department (ED) of one tertiary hospital from January 1, 2011, to December 31, 2012, with a diagnosis of radial head subluxation at discharge were enrolled in this study. Through retrospective chart reviews, factors that could have influenced the decision to perform an X-ray examination and their statistical relevance were analyzed. Results: A total 308 patients were enrolled, and 101 patients (32.8%) underwent X-ray examinations. Among the 252 patients with a typical pulled elbow, 65 underwent X-ray examination. This result showed statistical significance compared to atypical pull-elbow group (25.8% vs. 64.3%, p<0.001). Factors associated with the decision to perform an X-ray examination were analyzed using the Chi-square test and the Fisher's exact test. The mechanism of injury and consultation with an orthopedic surgeon (p=0.001) showed statistical significance. In the multivariable logistic regression, the odds ratio (OR) for the injury mechanism was 4.7 (95% CI: 1.8~8.8, p<0.001) and that for consultation with an orthopedic surgeon was 8.0 (95% CI: 1.6~40.7, p=0.004). Conclusion: One third of patients with a pulled elbow underwent X-ray examination, and patients with an atypical mechanism of injury underwent more frequent X-ray examinations than did patients with a typical mechanism of injury. The factors that could have influenced the decision to perform an X-ray examination were mechanism of injury and consultation with an orthopedic surgeon.

The purpose of this study was to contribute to family nursing in the areas of reducing stress and improving coping for parents of mentally retarded children. Data were collected through self-report questionnaires during a period of 2 months between November 1994 and January 1995 in the Kyoung-in area. The subjects consist of 176 parents (88 mothers and 88 fathers) of mentally retarded children attending schools for the handicapped. The levels of general stress and of parental role stress were measured with the General stress scale and the Parental role stress scale, respectively. The coping scale developed by Folkman ＆ LaZarus was adopted to measure the level of coping, and the patterns of adaptation scale developed by Damrosch ＆ Perry was adopted to measure the patterns of adaptation. The data were analyzed by a SAS program using Fisher's exact test, paired t-test, and oneway ANOVA. The results are as follows ; 1. The level of general stress was significantly higher in mothers than in fathers. Mothers experienced a significantly greater level of parental role stress than fathers did. No significant difference in the level of coping was observed between mothers and fathers. There were differences in maternal and paternal patterns of adaptation. 2. The adaptation pattern of fathers was different according to their level of general stress, parental role stress and coping. The adaptation pattern of mothers was not different according to their level of general stress and parental role stress, but was according to their level of coping. 3. General stress experienced by fathers was different according to education, health status and support from their spouses. Satisfaction with family life, satisfaction with spouse and the support from spouse influenced coping used by fathers. Their level of parental role stress was not associated with any of their general characteristics. 4. In mothers, the level of general stress was different according to their health status, the level of parental role stress was related to satisfaction with family life and satisfaction with spouse. Their level of coping was associated with the sup port from spouse. The above findings indicate that mothers did not have more coping strategies than fathers did, despite the results which showed that mothers experienced greater stress than fathers did. Especially, the adaptation pattern of mothers was different according to their level of coping. Hence, nursing interventions directed at managing stress and improving coping should be used with mothers who use adaptation pattern 1. In particular, fathers should actively participate in parenting, and support their spouses.

Background: Breast cancer (BCa) is the most common malignancy in Mexican women. A set of histopathological markers has been established to guide BCa diagnosis, prognosis and treatment. Nevertheless, in only a few Mexican health services, such as that of the Secretariat of National Defense (SEDENA for its acronym in Spanish), are these markers commonly employed for assessing BCa. The aim of this study was to explore the association of Ki67, TP53, HER2/neu, estrogenic receptors (ERs) and progesterone receptors (PRs) with BCa risk factors. Materials and Methods: Clinical histories provided background patient information. Immunohistochemical (IHC) analysis was conducted on 48 tissue samples from women diagnosed with BCa and treated with radical mastectomy. The Chi square test or Fisher exact test together with the Pearson and Spearman correlation were applied. Results: On average, patients were $58{\pm}10.4$ years old. It was most common to find invasive ductal carcinoma (95.8%), histological grade 3 (45.8%), with a poor Nottingham Prognostic Index (NPI; 80.4%). ERs and PRs were associated with smoking and alcohol consumption, metastasis at diagnosis and Ki67 expression (p<0.05). PR+ was also related to urea and ER+ (p<0.05). Ki67 was associated with TP53 and elevated triglycerides (p<0.05), and HER2/neu with ER+, the number of pregnancies and tumor size (p<0.05). TP53 was also associated with a poor NPI (p<0.05) and CD34 with smoking (p<0.05). The triple negative status (ER-/PR-/HER2/neu-) was related to smoking, alcohol consumption, exposure to biomass, number of pregnancies, metastasis and a poor NPI (p<0.05). Moreover, the luminal B subty was associated with histological type (p=0.007), tumor size (p=0.03) and high cholesterol (p=0.02). Conclusions: Ki67, TP53, HER2/neu, ER and PR proved to be related to several clinical and pathological factors. Hence, it is crucial to determine this IHC profile in women at risk for BCa. Certain associations require further study to understand physiological/biochemical/molecular processes.

Brillouin backscatter is a type of reflection that occurs when light is shone into an optical fibre. Brillouin reflections are very sensitive to changes in the fibre arising from external effects, such as temperature, strain and pressure. We report here several case studies on the measurement of strain using Brillouin reflections. A mechanical bending test of an I beam, deployed with both fiber optic sensors and conventional strain gauge rosettes, was performed with the aim of evaluating: (1) the capability and technical limit of the DTSS technology for strain profile sensing; (2) the reliability of strain measurement using fiber optic sensor. The average values of strains obtained from both DTSS and strain gauges (corresponding to the deflection of I beam) showed a linear relationship and an excellent one-to-one match. A practical application of DTSS technology as an early warning system for land sliding or subsidence was examined through a field test at a hillside. Extremely strong, lightweight, rugged, survivable tight-buffered cables, designed for optimal strain transfer to the fibre, were used and clamped on the subsurface at a depth of about 50cm. It was proved that DTSS measurements could detect the exact position and the progress of strain changes induced by land sliding and subsidence. We also carried out the first ever distributed dynamic strain measurement (10Hz) on the Korean Train eXpress(KTX) railway track in Daejeon, Korea. The aim was to analyse the integrity of a section of track that had recently been repaired. The Sensornet DTSS was used to monitor this 85m section of track while a KTX train passed over. In the repaired section the strain increases to levels of 90 microstrain, whereas in the section of regular track the strain is in the region of 30-50 microstrain. The results were excellent since they demonstrate that the DTSS is able to measure small, dynamic changes in strain in rails during normal operating conditions. The current 10km range of the DTSS creates a potential to monitor the integrity of large lengths of track, and especially higher risk sections such as bridges, repaired track and areas at risk of subsidence.
