This study was undertaken to investigate the factorial structure of clothing purchase motives, and to examine the relationship between clothing purchase motives, self-concept, and post-purchase clothing satisfaction of males. Questionnaire was comprised of three sections: 25 Likert type statements of clothing purchase motive measure; post-purchase clothing satisfaction measure; and three self-concepts measure(physical, personal, and social self-concept). For the measurement of self-concepts, a portion of‘Self-Concept Scale’by Wonshik Chung was used. Samples were 312 male white collar workers in Seoul, whose age were ranged from 20 to 39. the data were analyzed using factor analysis, Cronbach's alpha reliability coefficient, Pearson's correlation coefficient, and multiple regression analysis. The results of the study were the followings: 1. Six factors of clothing purchase motives derived by factor analysis. 21 items having a factor loading of ± .40 or higher were given consideration in the interpretation of each factor: F.1‘clothing dsign’; F.2‘fashion and impulsive buying’, F.3‘clothing utility’; F.4‘others influence’: F.5‘financial margin’; F.6‘clothing’2. Male consumers perceived the purchase motive of‘clothing design’to be the most important,‘clothing deficiency’the second important, and‘others influence’the least important. 3. Physical, personal, and social self-concept had positive relations to the purchase motive of‘clothing design’and negative relations to the‘clothing deficiency’. Physical self-concept had negative relation to the motive of‘others influence’. 4. Male consumers high in physical, personal, and social self-concept had more positive attitude in the evaluation of post-purchase clothing satisfaction. 5. Post-purchase clothing satisfaction was influenced most by the purchase motive of‘clothing design’, and next by physical self-concept, and age. Age of subjects had negative relation to post-purchase clothing satisfaction. The explanatory power of the 3 variables was 19.9%.

Purpose: To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). Materials and Methods: We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. Results: The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or ${\geq}1$ mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). Conclusion: Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

This is a retrospective cohort analysis of 58 patients who treated with postoperative radiation therapy following radical hysterectomy and bilateral pelvic adenectomy for early stage carcinoma of uterine cervix between January 1988 and December 1990 at department of radiation oncology, Keimyoung University Hospital. Sixteen percent of patients (9/58) had chemotherapy. Most patients were FIGO I b (47 patients), and FIGO I a and II a were one and ten patients, respectively. The median follow-up periods were 48.5 months. The indications for radiation therapy included pelvic lymph node metastasis, large tumor size, deep stromal invasion, lymphovascular invasion, positive surgical margin, endometrial invasion and parametrial invasion. Eighty five percent of the patients had more than one risk factor. The actuarial overall five year survival rate (5 YSR) and five year disease free survival rate (5 YDFSR) were $89.5\%,\;and\;87.8\%,$ respectively. Their overall recurrence rate was $12.1\%,$(758). Distant metastasis was the most common cause of treatment failure $(71.4\%:5/7).$ The univariate analysis of prognostic factors affecting to five year survival rate disclosed pelvic lymph node status (negative: $95.5\%,\;positive:69.2\%,$ p=0.006) and hemoglobin level $(\le11 :75\%,>11g/dl:93.3\%,p=0.05)$ as significant factor. The age status was marginally significant $(\le40:96.0\%,\;>\;40:84.3\%p=0.15).$ Multivariate analysis clarified three independent prognostic factors: pelvic lymph node metastasis (p=p.006), hemoglobin level (p=0.015) and age (p=0.035). Multivariate analysis of prognostic factor affecting to five year disease free survival rate disclosed pelvic lymph node status (p=0.0078) and status of surgical margin (p=0.008). Complications relating to radiotherapy were $10.3\%,(6/58).$ There were no severe major complication requiring surgical intervention or a long hospital stay. It is our opinion that the benefit of postoperative pelvic radiotherapy may be gained in such a high risk patient population with acceptible morbidity.

Objective: To compare the diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3-tesla (3T) magnetic resonance imaging (MRI) and computed tomography (CT) for the detection of visceral pleural surface invasion (VPSI). Visceral pleural invasion by non-small-cell lung cancer (NSCLC) can be classified into two types: PL1 (without VPSI), invasion of the elastic layer of the visceral pleura without reaching the visceral pleural surface, and PL2 (with VPSI), full invasion of the visceral pleura. Materials and Methods: Thirty-three patients with pathologically confirmed VPSI by NSCLC were retrospectively reviewed. Multidetector CT and contrast-enhanced 3T MRI with a free-breathing radial three-dimensional fat-suppressed volumetric interpolated breath-hold examination (VIBE) pulse sequence were compared in terms of the length of contact, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. Supplemental evaluation of the tumor-pleura interface (smooth versus irregular) could only be performed with MRI (not discernible on CT). Results: At the tumor-pleura interface, radial VIBE MRI revealed a smooth margin in 20 of 21 patients without VPSI and an irregular margin in 10 of 12 patients with VPSI, yielding an accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and F-score for VPSI detection of 91%, 83%, 95%, 91%, 91%, and 87%, respectively. The McNemar test and receiver operating characteristics curve analysis revealed no significant differences between the diagnostic accuracies of CT and MRI for evaluating the contact length, angle of mass margin, or arch distance-to-maximum tumor diameter ratio as predictors of VPSI. Conclusion: The diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3T MRI and CT were equal in terms of the contact length, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. The advantage of MRI is its clear depiction of the tumor-pleura interface margin, facilitating VPSI detection.

Soft tissue tumors of the foot have a low incidence rate, and most of them are symptom free, thus it is difficult to diagnose accurately. Herein, we report a 15-year-old male patient who had swelling without pain on the lateral margin of both feet. We performed excisional biopsy of the abductor digiti minimi via subtotal resection, following radiograph and magnetic resonance imaging. According to the histological analysis, hypertrophy of abductor digiti minimi was positive, and other soft tissue tumors were negative. Six months after the operation, normal appearance of both feet was maintained and the patient was satisfied with the result.

This paper presents floating absorber for safety at transient (FAST) which is a passive safety device for sodium-cooled fast reactors with a positive coolant temperature coefficient. Working principle of the FAST makes it possible to insert negative reactivity passively in case of temperature rise or voiding of coolant. Behaviors of the FAST in conventional oxide fuel-loaded and metallic fuel-loaded SFRs are investigated assuming anticipated transients without scram (ATWS) scenarios. Unprotected loss of flow (ULOF), unprotected loss of heat sink (ULOHS), unprotected transient overpower (UTOP) and unprotected chilled inlet temperature (UCIT) scenarios are simulated at end of life (EOL) conditions of the oxide and the metallic SFR cores, and performance of the FAST to improve the reactor safety is analyzed in terms of reactivity feedback components, reactor power and maximum temperatures of fuel and coolant. It is shown that FAST is able to improve the safety margin of conventional burner-type SFRs during ULOF, ULOHS, UTOP and UCIT.

200 cases of pulmonary tuberculosis patients treated by surgical resection were anlized Bronchial resection margin was examined by microscopic study to detect submucosal tuberculosis granuloma. 6 cases of bronchopleural fistula that occurred after resection were also asnalized to fond any relation with submucosal granuloma. Among 200 cases, 19 cases (9.5%) showed submucosal granu- loma. Of the 19 cases, 2 cases (10.5%) developed ea ly and late bronchopleural fistula On the con- trary, only 2.2% developed in granuloma negative cases. Granuloma positive cases were mote fre- quently seen in preoperative sputum positive cases and showed incidence of residual pleural dead space resection.

A 13-year-old spayed female American cocker spaniel dog was submitted to an animal hospital with a mass from left ear canal and enlarged left parotid lymph node. Given one-year history of odorous exudates and chronic otitis externa, total ear canal ablation was performed. Grossly, because of the neoplastic mass in both inner and outside of annular cartilage in external ear, vertical ear canal was severely narrowed. Histologically, there were numerous proliferated glands in the ear canal mass. Many neoplastic glands contained secretory vesicles on the free margin and necrotic cellular debris. Severe multifocal necrosis and strong invasion were also observed throughout the mass. Massive metastatic foci of glandular structures originated from ceruminous gland were presented in the enlarged parotid lymph node. Neoplastic glandular epithelia contained PAS-positive diastase-resistant eosinophilic cytoplasmic granules. Immunohistochemically, the neoplastic cells showed positive reactions for cytokeratin (CK) 7 and negative for CK 5/6. Based on the clinical implication and gross findings, histopathology and immunohistochemistry, this case was diagnosed as metastatic ceruminous gland adenocarcinoma in the American cocker spaniel.

Purpose This study aims to analyse the impact of the development of fintech and the emergence of internet primary banks due to the increasing use of smartphones on the performance of traditional local banks from both financial and non-financial perspectives. Return on equity (ROE) and return on assets (ROA) are used to assess the performance differences between the two types of banks and how these differences are affected by their financial characteristics. Design/methodology/approach Using return on equity (ROE) and return on assets (ROA) as indicators, we identified the differences in operating performance between the two types of banks. In addition, this study analysed the impact of financial characteristics on profitability through regression analysis with various control variables. We further studied the impact of non-financial characteristics (customer reviews, social media reactions, etc.) on operating performance. Findings The net interest margin ratio of local banks had a positive impact, while the marketable securities ratio of Internet primary banks had a negative impact. The non-financial analysis shows that the number of customer reviews and social media reactions have a significant impact on the performance of Internet primary banks, suggesting that customer satisfaction and positive market perception are important factors in the performance of Internet primary banks.

This study investigates firm-specific financial variables that determine investment or speculative grades from the viewpoint of firms, which are one of the major stakeholders related to the credit rating. We employ an ordered probit model for our analysis with the sample data from 1999 to 2015 for listed firms in the Korean stock markets. For investment grades, operating margin, sales, market-to-book, dividend payment, capital expenditure ratio, and tangible asset ratio have a significantly positive impact on credit ratings. In the subsample for speculative grades, the coefficients of the dividend payment, retained earnings ratio, and capital expenditure ratio are significantly positive while short-term debt ratio and R&D expenditures have a significantly negative impact on credit ratings. For the analysis before and after 2009, when the Credit Information Use and Protection Act was strengthened after the global financial crisis, the coefficients of the capital expenditure ratio, cash ratio, and tangible asset ratio are significantly positive in the subsample for investment grades before 2009, but not significant after 2010. The coefficient of the long-term debt ratio is more significantly negative than that of the short-term debt ratio before 2009, for speculative grades, but short-term debt ratio has a more negative effect on ratings than long-term debt ratio after 2010. Surprisingly, the coefficient of the R&D expenditures is significantly negative in both investment and speculative grades since 2010. Our findings are inconsistent with the conjecture that the increase in R&D expenditures enhances the possibility of creating cash-flow by raising the investment growth opportunity, and thus affects positively the credit rating.
