This study is attempted to define risk factor of youth runaway impulse and to structure forecast model through an extensive analysis of the factors influencing the runaway impulse of youth. The subjects were 610 high school students in Seoul and Kyunggido. The collected data was analysed by SAS. The differences between the runaway impulse group and the non-runaway impulse group were subject to chi-square and t-test. Also logistic regression analysis was conducted on the basis of purposeful selection method for constructing the forecast model. The findings are as follows : the major predicting factors of youth runaway impulse are sex(odds ratio=1.886, p=.009), existence of friends of the opposit sex(odds ratio=2.011, p=.007), anti-social personality(odds ratio= 4.953, p=.000), depressive trend(odds ratio= 2.695, p=.000), family structure(odds ratio= 5.381, p=.000), marital relationship(odds ratio =1.893, p=.009) and also between parents and youth(odds ratio=3.877, p=.000), emotional abuse(odds ratio=1.963, p=.003), authoritative controlled rearing(odds ratio=2.135, p=.005) and stress from school(odds ratio=1.924, p=.008). Therefore, the forecast model will be contribute to the nursing intervention for prevention of runaway youth.

PURPOSE: This study was designed to explore the perceptions of quality nursing care among nurses. METHOD: The data were analyzed using content analysis. The data were collected from 19 nurses who worked at diverse clinical areas in 8 general and university hospitals with over 400 beds. RESULT: 1. The attributes of quality nursing care were categorized into 7 hierarchies in the order of 'caring' (40.65%), 'specialty' (29.03%), 'nurse attainments' (15.48%), 'patient- centered nursing management' (6.45%), 'sincerity' (5.16%), 'kindness' (2.58%), 'satisfaction' (0.65%). 2. The concept of quality nursing care were defined as 'giving a satisfaction both to patients and nurses through patient-centered nursing management with specialty and caring in the ground of the kindness and sincerity'. CONCLUSION: Based on there findings, we suggest that the study results should be used for development of a quality assurance tool in nursing practice, patient care in hospital setting, education of nurses and nursing students. In addition, further repeated studies need to be conducted.

PURPOSE: This prospective study was to compare the image quality and diagnostic performance of breast cystic masses by conventional and advanced ultrasound (US) techniques including tissue harmonic, compound, and the combination of these techniques. MATERIALS AND METHODS: All 91 patients, collectively having 109 breast cystic masses were scanned using four US techniques (complicated cysts in 36, septated cysts in 33, and complex cysts in 40). Two breast radiologists independently assessed the image quality and possibility of malignancy. Image quality was evaluated in terms of contrast and clarity of the wall and internal echo pattern and then graded on a scale of 1 (poor) to grade 3 (satisfactory). The possibility of malignancy was graded on a scale of 1 (suggestive of benignancy) to 5 (suggestive of malignancy) using US images. The histopathological results and follow-up images were used as the reference standard for the assessment of diagnostic performance. Results were evaluated by Friedman's test and receiver operating characteristic (ROC) analyses. RESULTS: In terms of image quality, a grade of 3 was significantly more frequent in the three advanced US techniques than conventional US (p < 0.05). For assessment of diagnostic performance, areas under the ROC curves in three advanced techniques were significantly higher than in conventional US (p < 0.05). CONCLUSION: Advanced US techniques including compound and tissue harmonic US techniques provide a better image quality in breast cystic masses and also improve the diagnostic performance compared with conventional US.

PURPOSE: To investigate the clinical use of low-dose multidetector row computed tomography (MDCT) for staging of invasive breast cancers with patients in the prone position. METHODS: Three hundred twenty-two patients with 334 pathologically-verified breast cancers had low-dose MDCT breast imaging in the prone position for tumor staging before treatment between May 2006 and June 2010. We designed an additional computed tomography table pad with a hole for prone positioning. Patients lay prone on the table pad and the breasts were positioned within the rectangular hole. We obtained dynamic breast imaging from the lower neck to the lung base with the following parameters: 120 kVp, 50 mAs, and 3-mm reconstruction intervals. We evaluated the extent of the primary tumor, lymph nodal status, and distant metastasis in lung or bone, then assessed tumor staging based on the TNM classification of breast cancer. The assessed staging compared to the pathologic results for diagnostic accuracy. RESULTS: Among the 334 invasive breast cancers, the overall diagnostic accuracy of tumor staging was 88.3% and the accuracy values of each tumor stage were 89.6% in T1, 90.8% in T2, 81.0% in T3, and 89.3% in T4. The overall diagnostic accuracy of lymph nodal staging was 86.3% and the accuracy values in each nodal stage were 82.9% in N0, 88.0% in N1, 89.7% in N2, and 93.3% in N3. Based on breast computed tomography scans, we detected distant metastases in 30 cases (7 lungs, 10 bones, 7 lungs and bones, and 6 livers). CONCLUSION: Low-dose MDCT scanning for invasive breast cancer patients in the prone position is a feasible imaging technique for tumor staging before treatment to evaluate primary breast tumors, lymph nodes, lungs, or thoracic bones with reduced radiation doses.

PURPOSE: To investigate the significance of the cortex-hilum (CH) area ratio and longitudinal-transverse (LT) axis ratio and the blood flow pattern for diagnosis of metastatic axillary lymph nodes by ultrasound in breast cancer patients. METHODS: From October 2005 to July 2006, we prospectively evaluated axillary nodes with ultrasound in 205 consecutive patients who had category 4B, 4C or 5 breast lesions according to the Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-Ultrasound(R)). Among the 205, there were 24 patients who had pathologic verification of breast cancer and axillary lymph node status. For a total of 80 axillary nodes we measured the areas of the cortex and hilum of lymph nodes and calculated the area ratio. We also measured the length of the longitudinal and transverse axis of the lymph nodes and calculated the length ratio. We evaluated the blood flow pattern on power Doppler imaging and classified each lymph node into a central or peripheral pattern. Diagnostic performance was analyzed according to positive criteria for lymph node metastasis (CH area ratio >2, LT axis ratio <2, peripheral type on power Doppler imaging). RESULTS: The sensitivity of the CH area ratio was superior to that of the LT axis ratio (94.1% vs. 82.3%, p=0.031) and to that of the blood flow pattern (94.1% vs. 29.4%, p=0.009). For specificity, all three evaluating parameters had high values (89.1-95.6%) and no significant differences were found (p=0.121). The CH area ratio had a better positive predictive value than the LT axis ratio (94.1% vs. 80.0%, p=0.030) and power Doppler imaging (94.1% vs. 66.6%, p=0.028). For the negative predictive value, the CH area ratio was superior to the LT axis ratio (95.6% vs. 86.6%, p=0.035) and the blood flow pattern (95.6% vs. 63.0%, p=0.027). CONCLUSION: We recommend the CH area ratio of an axillary lymph node on ultrasound as a quantitative indicator for the classification of lymph nodes. The CH area ratio can improve diagnostic performance when compared with the LT axis ratio or blood flow pattern.

Autologous fat injection is one of the methods utilized for augmented mammoplasty methods. In this surgical procedure, the fat for transfer is obtained from the donor site of the patient's own body by liposuction and the fat is then injected into the breast. We report here cases of three patients who underwent autologous fat injection. Two of the patients had palpable masses that were present after surgery. The serial imaging findings and surgical method of autologous fat transfer are demonstrated.

OBJECTIVE: Ultrasound-guided needle localization has been used prior to the surgical excision of nonpalpable breast lesions. The aim of the study was to assess the feasibility of the use of a saline immersion specimen ultrasound technique (immersion-US) to confirm the successful removal of breast lesions. MATERIALS AND METHODS: The devised immersion-US technique was used to examine the excised tissues of 72 ultrasound-guided needle localized breast lesions of 58 patients (34 benign lesions, 30 high-risk lesions and 8 malignant lesions). Freshly excised specimens were placed in a container filled with saline and one radiologist scanned the surgically excised specimens using a high-frequency linear transducer. We evaluated successful lesion removal and the qualities of the immersion-US images. Miss rates were determined by the use of postoperative ultrasound during follow-up. RESULTS: All 72 lesions were identified by the use of immersion-US and satisfactory or excellent quality images were obtained for most lesions (70/72, 97%). Five (7%) lesions were initially identified as incompletely excised, based on the immersion-US findings, and prompt re-excision was undertaken. Follow-up ultrasound examinations showed no residual mass in the surgical field in any patient. CONCLUSION: The immersion-US technique was found straightforward and efficient to perform. Immersion-US was able to determine whether nonpalpable breast lesions had been successfully excised after ultrasound-guided needle localization.
