  • This study attempts to analyze the propensity for conspicuous consumption of the adolescent consumers and related variables such as socio-economic variables, consumer experience, materialism and consumption-oriented attitudes to provide a basis for the development of consumer education program. The survey of this research was conducted by means of self admistered questionnaire with 788 adolescent consumers attending middle and high school located in Ulsan. The results of this research were as follows: 1) The average level of the propensity for conspicuous consumption was a little high median point. This implies that consumer education is necessary for the adolescent consumer in order to reduce the level of conspicuous consumption. 2) The adolescent consumers' propensity for conspicuous consumption varies significantly according to the socio-economic variables such as sex, grade, the allowance interval, the amount of allowance, the mother's education and the subjective level of household consumption. 3) The propensity for conspicuous consumption is positively correlated with materialism and the consumption-oriented attitudes. The consumer experience is positively correlated with materialism and not significantly correlated with the propensity for conspicuous consumption and the consumption-oriented attitudes. Materialism is positively correlated with the consumption-oriented attitudes. 4) According to the results of the regression analysis examining the influences of variables affecting the propensity for conspicuous consumption, the relative importance of the variables are in the order of; materialism, the consumption-oriented attitudes, sex and the amount of allowance. These independent variables explains 49.3% of the total variance about the propensity for conspicuous consumption.

  • This study presents a descriptive statistical analysis on grade characteristics and employment rates of three ocean-related departments at a university. The ocean-related departments belong to the same college along with the other six departments. To obtain the correlation between the grade characteristics and employment rates, we carried out the followings. Firstly, four-year employment rates and six-semester GPAs (grade point averages) were obtained from the nine departments. Secondly, the box-and-whisker plots were constructed for each data set to capture the grade characteristics (mean, the first quartile, median, third quartile, whisker+, and Q3 box). Finally, the grade characteristics and employment rates were correlated. It is shown from the correlation analysis that the employment rate has a positive linear relation with the mean or third quartile, while the rate has a negative linear relation with the whisker+ or Q3 box, for the ocean-related departments possibly because these departments have higher regular employment rates than those of the other six departments.

  • There are many wrist and hand diseases in which ultrasound can help in the diagnosis and treatment. Because many small structures are located, identifying anatomical locations and pathways is especially important. In De Quervain's syndrome, it is necessary to find tendon lesions located in the first compartment of the wrist. If injection therapy is required, administer the regimen accurately within the tendon sheath through ultrasound. In carpal tunnel syndrome, there are several methods to diagnose a disease by measuring cross-sectional area of the median nerve. Ultrasound has the advantage of administering injection therapy without damaging the nerve. Intersection syndrome can be diagnosed by observing swelling and hypoechoic appearances at the point where the tendons of the first compartment cross over the second compartment of the wrist. Ultrasound-guided injection is also safe and efficient. If there is a trigger finger lesion, the most representative findings is to observe a nodular hypoechoic thickening of the involved A1 pulley. When injection therapy is performed, it is effective to administer medication between pulley and flexor tendons as much as possible to reduce pressure on the attached structures.

  • To improve the effect of image restoration and solve the image detail loss, an image dehazing enhancement algorithm based on mean guided filtering is proposed. The superpixel calculation method is used to pre-segment the original foggy image to obtain different sub-regions. The Ncut algorithm is used to segment the original image, and it outputs the segmented image until there is no more region merging in the image. By means of the mean-guided filtering method, the minimum value is selected as the value of the current pixel point in the local small block of the dark image, and the dark primary color image is obtained, and its transmittance is calculated to obtain the image edge detection result. According to the prior law of dark channel, a classic image dehazing enhancement model is established, and the model is combined with a median filter with low computational complexity to denoise the image in real time and maintain the jump of the mutation area to achieve image dehazing enhancement. The experimental results show that the image dehazing and enhancement effect of the proposed algorithm has obvious advantages, can retain a large amount of image detail information, and the values of information entropy, peak signal-to-noise ratio, and structural similarity are high. The research innovatively combines a variety of methods to achieve image dehazing and improve the quality effect. Through segmentation, filtering, denoising and other operations, the image quality is effectively improved, which provides an important reference for the improvement of image processing technology.

  • Purpose : To obtain the optimal treatement method in patients with endometrial carcinoma(clinical stage FIGO I, II) by comparative analysis between preoperative radiotherapy (pre-op RT) and postoperative radiotherapy (post-op RT). Material and Methods : A retrospective review of 62 endometrial carcinoma patients referred to the Yonsei Cancer Center for radiotherapy between 1985 and 1991 was undertaken. Of 62 patients, 19 patients(Stagel : 12 patients. Stagell;7 patients) received pre-op RT before TAH(Total Abdominal Hysterectomy) and BSO (Bilateral Salphingoophorectomy) (Group 1) and 43 patients(Stage 1;32 patients, Stage 2; 11 patients) received post-op RT after TAH and BSO (Group 2). Pre-op irradiation was given 4-6 weeks prior to surgery and post-op RT administered on 4-5 weeks following surgery. All patients except 1 patient(Group 2: ICR alone) received external irradiation. Seventy percent(13/19) of pre-op RT group and 54 percent(23/42) of post-op RT group received external pelvic irradiation and intracavitary radiation therapy(ICR). External radiation dose was 39.6-55 Gy(median 45 Gy) in 5-6. 5weeks through opposed AP/PA fields or 4-field box technique treating daily, five days per week, 180 cGy per fraction. ICR doses were prescribed to point A(20-39.6 Gy, median 39 Gy) in Group 1 and 0.5cm depth from vaginal surface (18-30 Gy,median 21 Gy) in Group 2. Results : The overall 5 year survival rate was $95{\%}$. No survival difference between pre-op and post-op RT group.($89.3{\%}$ vs $97.7{\%}$, p>0.1) There was no survival difference by stage, grade and histology between two groups. The survival rate was not affected by presence of residual tumor of surgical specimen after pre-op RT in Group 1 (p>0.1), but affected by presence of lymph node metastasis in post-op RT group(P<0.5). The complication rate of pre-op RT group was higher than post-op RT. ($16{\%}$ vs $5{\%}$) Conclusion : Post-op radiotherapy offers the advantages of accurate surgical-pathological staging and low complication rate.

  • The purpose of this study is to prepare the basic information of teacher training through the special education teachers' present execution status and awareness on positive behavior intervention support for the student with disabilities. The results of the study as follows: First, the rate of teachers having high concern on students' behavioral management was 22.9%, and the rate of teachers taking median concern was 66%. And the teachers obtained the information on problem management including positive behavior support by publications or teacher training. Second, the importance of individual interventions valuated significantly which presented mostly more 4 point. But relatively the point of application possibility was lower than the point of importance evaluation. Third, the rate of application as 70% among total research participants presented to be used the most in all individual interventions on positive behavior support. And on the effectiveness, the teachers answered that 23 interventions were effective. But, on the facts of monitoring and assessment of behaviors, the special education teachers negatively evaluated the effectiveness. Results are discussed with previous research, contributions to future directions, and implications in interventions for students with disabilities.

  • Background: To investigate the impact of ovarian transposition (OT) on survival rates of the patients with stage Ib squamous cell cervical cancer. Materials and Methods: Ninety-two subjects who underwent a radical hysterectomy including oophorectomy were evaluated. For nineteen (20.7%), OT was performed. Patients were divided into two groups, OT versus oophorectomy alone. The primary end-point of this study was to investigate the impact of OT on tumor recurrence rate and time, 5-year disease-free survival (DFS) and overall survival (OS). These comparisons were performed for subgroups including patients who received radiotherapy versus who did not. Statistical analyses were conducted using the Chi-square test, T-test and Mann-Whitney test. OS was examined using the Kaplan-Meier method. $P{\leq}0.05$ was considered to be statistically significant. Results: The median follow-up period was 89 months for OT and 81 months for the oophorectomy group (p>0.05). Both groups experienced similar recurrence rates (31.6% vs. 26.4%, p=0.181). The median duration from surgery to recurrence, and surgery to death were also similar between the groups (p>0.05). The 5-year DFS and OS rates were both 68.4% for the OT group, and 73.6% and 77.8% for the oophorectomy group (p=0.457 and p=0.307, respectively). While the 5-year DFS rate was not statistically significant between the OT and oophorectomy groups who did not receive radiotherapy (p=0.148), the 5-year OS rate was significantly higher in the oophorectomy group (95.4% vs 66.7%, respectively) without radiotherapy (p=0.05). The 5-year DFS and OS rates were statistically similar between the groups who received adjuvant radiotherapy (p>0.05). Conclusions: Ovarian transposition has not significantly negative effect on the survival rates when adjuvant radiotherapy will be applied, while 5-year OS may be less in OT group if radiotherapy is not mandatory.

  • Background: Previous reports have shown that human epidermal receptor (HER)-3 overexpression may be associated with poor prognosis in patients with breast cancer, but results have been conflicting. In this study, we sought to investigate the prognostic significance of HER-3 immunohistochemical expression in patients with metastatic breast cancer. Methods: We retrospectively analyzed HER-3 immunohistochemical expression profiles in 45 paraffin-embedded specimens from patients who had been treated between 1996 and 2006 in the Department of Oncology of the Uludag University School of Medicine, Bursa, Turkey. Membranous or cytoplasmic dominant expression patterns of HER-3 were analyzed using the Rajkumar score and a cytoplasmic 4-point scoring system, respectively. Progression-free survival (PFS) and overall survival (OS) served as the main outcome measures. Results: The median PFS in the study participants was 9 months (interquartile range: 4.5-13 months), whereas the median OS was 20 months (interquartile range: 7.5-28 months). Categorization of the patient population according to HER-3 positive immunohistochemical expression did not reveal any statistically significant difference in terms of both PFS (p=0.70) and OS (p=0.81). The results of multivariable Cox regression analysis indicated that tumor size was the only independent predictor of PFS, whereas estrogen and progesterone receptor status was independently associated with OS. Conclusions: HER-3 immunohistochemical expression did not correlate with outcomes in Turkish patients with metastatic breast cancer. Although our results suggest that HER-3 expression in cancer specimens is not of prognostic significance, further prospective studies are warranted to confirm these results.
