The Power and Knowledge are attractive materials that could be used in all of cultural content genre with storytelling. Because he, whether or not own knowledge, could be an important tool of narrative strategy for popularity keeping with a confrontation and conflict. This study aimed to explore the power and knowledge appearing in . For this purpose, it used the structuralistic methodologies of Saussure and Levi-Strauss, analyzing binary oppositions between the characters mainly connected with the knowledge and power. Three categories was analytic object, 'Place(abbey, book repository)' 'Debate on laughter', 'The argument for heresy.' As a result, we found the three materials had narrative strategy fully following binary oppositional structure. In that movie, which was deployed in a basis with knowledge and power, we eventually found that contemporary reality veiled the truth was paradoxically revealed with these narrative strategy. And we confirmed that it was very important the attribute of knowledge and power in narrative processing.

In this paper we propose a new software project development management model incorporating quality management to schedule management. Though many efficient techniques such as code review and inspection are used to remove defects, the effect of defect removal time on project schedule hasn't been studied much. However, poor quality management has an important effect upon overall schedule and sometimes software projects fails due to it. Thus, quality management and schedule management should be considered together and we need to reflect the time to maintain software quality into the schedule management. For the proposed model we introduced "Quality Value" representing the needed time to remove software defects. We assume PSP/TSP to gather the needed data for quality value. The proposed model can be used to predict the effect of software defects on schedule in advance and to prevent schedule lag.

Background: The incidence of cervical esophageal cancer is low compared with that of thoracic esophageal cancer, and the role of surgery for cervical esophageal cancer is limited compared with that of radiotherapy or chemotherapy. This study was carried out to determine the outcome of surgery for cervical esophageal cancer. Material and Method: We analyzed retrospectively medical records of 43 patients who had undergone curative surgical resection for cervical esophageal cancer from January 1989 to December 2002. Follow-up loss was absent and the last follow-up was carried out in February 28, 2004. Result: The mean age was 60 years old and the male to female ratio was 40:3. Histologic types were squamous cell carcinoma 42 patients and malignant melanoma 1 patient. The methods used for esophageal reconstruction were gastric pull-up 32 patients, free jejunal graft 7 patients and colon interposition 4 patients. Postoperative complications occurred in 31 patients (72%), and operative mortality occurred in 7 patients (16%). Pathologic stages were I 3, IIa 14, IIb 1, III 19, and IVa 6 patients. Tumor recurrence occurred in 16 patients (44%), and the 3 and 5-year survival rates were 29.3% and 20.9%. Conclusion: The reported surgical results for cervical esophageal cancer showed somewhat high operative mortality, postoperative complication rates and recurrence rates and a low long-term survival rate. It is suggested that multimodality treatment including surgery is needed for the treatment of cervical esophageal cancer because radiotherapy or chemotherapy without surgery could not relieve dysphagia or resolve the tumor completely.

Purpose: To report on the clinical outcome of patients with stage I testicular seminoma by postoperative radiotherapy (PORT) or surveillance after radical inguinal orchiectomy. Materials and Methods: This study is a retrospective review of 32 stage I pure seminoma patients treated between 1996 and 2005 at the Samsung Medical Center. Twenty two of the patients were treated by PORT, which was directed at the paraaortic lymphatics with a median dose of 25.2 Gy in 14 fractions for 3 weeks. The 10 remaining patients were managed by surveillance. The median follow-up period was 96 months with a range of 24 to 155 months. Results: Clinically, most patients presented with a testicular mass or discomfort. Two of the patients had a history of undescended testes. Pathologically, 23 of the patients had intratubular germ cell neoplasia with seminoma. Both recurrence-free survival (RFS) and overall survival (OS) rates of patients treated by PORT were 100%. In the control group, 1 of the 10 patients suffered a para-aortic lymph node relapse. The RFS and OS rates of the surveillance group were 88.9% and 100%, respectively. Conclusion: No difference in survival was observed between the two groups. Moreover, symptom recurrence was only observed in 1 patient in the control group. The use of PORT may reduce the risk of relapse. With the availability of effective diagnostic and salvage modalities, surveillance monitoring may be considered for patients in good compliance.

Panorama image is a single image obtained by combining images taken at several viewpoints through matching of corresponding points. Existing panoramic image generation methods that find the corresponding points are extracting local invariant feature points in each image to create descriptors and using descriptor matching algorithm. In the case of video sequence, frames may be a lot, so therefore it may costs significant amount of time to generate a panoramic image by the existing method and it may has done unnecessary calculations. In this paper, we propose a method to quickly create a single panoramic image from a video sequence. By assuming that there is no significant changes between frames of the video such as in locally, we use the FAST algorithm that has good repeatability and high-speed calculation to extract feature points and the Lucas-Kanade algorithm as each feature point to track for find the corresponding points in surrounding neighborhood instead of existing descriptor matching algorithms. When homographies are calculated for all images, homography is changed around the center image of video sequence to warp images and obtain a planar panoramic image. Finally, the spherical panoramic image is obtained by performing inverse transformation of the spherical coordinate system. The proposed method was confirmed through the experiments generating panorama image efficiently and more faster than the existing methods.

Purpose: The aim of this study was to evaluate the usefulness of FDG-PET/CT as follow up imaging tool in patients with endometrial cancer after therapy. Material and Methods: One hundred one patients with endometrial cancer who underwent FDG PET/CT after the treatment of this disease were included in this study population (25-79 yr old, Mean age 50.6 yr old) and all these patients also performed various laboratory and imaging studies such as serum tumor marker, CT or MRI. The lesions having increased focal FDG uptake were classified into benign, equivocal, and malignant one according to their pattern and activity. Tumor recurrence was confirmed by histopathological results and other clinical and imaging data. Results: Among the 19 patients with 30 malignant or equivocal hot uptakes, 11 of 14 patients supposed to be malignant finding in PET/CT were proved to be tumor recurrence, while one of 5 patients with equivocal lesions were recurred malignancy, Two false negative cases were turned out to be peritoneal carcinomatosis, Estimated sensitivity, specificity and accuracy of PET/CT for diagnosis of recurrence in endometrial carcinoma after treatment were 86 %, 92 % and 91 %, respectively. Positive and negative predictive values in the same issue were 63% and 98%, respectively. Conclusion: FDG-PET/CT is useful for regular work up of endometrial carcinoma after the treatment because of its high negative predictive value as well as high sensitivity and specificity.

The purpose of this study compared the clinical features of suicidal attempters who visit in the past and present of an emergency medical center, used as a basic data for clinical severity and suicide prevention research of future patients. The author conducted a retrospective analysis of the changed characteristics of suicidal attempters who visit an emergency medical center of Wonkwang University Hospital between from January $1^{st}$, 1998 to December $31^{th}$, 1998 and from August $1^{st}$, 2013 to July $31^{th}$, 2015. Factors related to increased occurrence was changed from male(1.1:1) in 1998 to female(1.3:1) in 2013-2015, from age of $2^{nd}$, $3^{rd}$, and above $6^{th}$ decade in 1998 to $3^{rd}-5^{th}$ decade in 2013-2015. Poisoning was the most common method of suicidal attempt(90.8%;1998, 72.7%;2013-2015), Mortality rate was changed from 16.9%(male 23.1%, female 10.0%) in 1998 to 13.8%(male 18.1%, female 10.5%) in 2013-2015. Among the suicidal attempters(total=516), 37 patients has recurred. But consultant of neuropsychiatric department was 48.3%, All suicidal attempters in future were necessarily neuropsychiatric consultant and continuously follow-up because all patients had recurrent suicide attempt, psychologic disorder, suicide rates are higher than in the general population.

To measure the birth registration rate and the validity of birth registration data in rural area, all of the 4,014 married women under 49 years of age who had not been sterilized in Gunwee county of Kyungpook province were followed by Myun health workers for 2 years from April 1, 1985 to March 31, 1987 and 766 births were detected. All of the birth registration records of Myun offices were reviewed on September 30, 1987 and 944 births which occurred within the above mentioned period were found. Actual birth date obtained by follow-up study were compared with the birth date on registration card. Among 766 births detected by follow-up study,576 births(75.2%) which were reported within 6 months after birth were ascertained on the official registration records and 96 births(12.5%) were not found on the records although mother stated that the birth was registered. The registration rate within legal due date was 61.3% among 576 births detected by follow-up study and also ascertained on the official records. The registration rate within legal due date was lower in mothers under 20 years of age and above 35 years and in mothers who had only primary education. It was decreased as the birth order increased. The registration rate was higher in births occurred from October to March than births occurred from April to September. All of the births of 7 neonatal deaths were not reported. The registered birth date was consistent with the actual birth date in 78.0%. Birth date on record was earlier than the actual birth date in 6.8% and later in 15.3%. The consistency rate was lower in mothers above 35 years of age(54.5%), and in infants of 4th birth order and above(56.3%). The rate was increased as the maternal education level increased. The rate of boys was higher than that of girls. A higher percentage(17.4%) of infants born in March was registered with earlier date than the actual birth date and most of these registered birth dates were lunar calendar date. This might be related with the age for entering the primary school. The study findings revealed that the birth registration rate within legal due date and accuracy of report have been increased in recent years, but the infant mortality rate derived from the birth registration seems to be very inaccurate. It is suggested to let the medical personnel who delivered the baby report the birth by mail directly to the current address of parent while infants delivered at home without professional attendant may comply with the present registration system.

Purpose : This study is to evaluate the efficacy of small bowel displacement system(SBDS) in post-operative pelvic radiation therapy(RT) of rectal cancer patients by measurement of small bowel volume included in the radiation fields receiving therapeutic dose. Materials and Method : Ten consecutive new rectal cancer patients referred to the department of Radiation Oncology of Samsung Medical Center in May of 1997 were included in this study. All patients were asked to drink $Castrographin^(R)$ before simulation and were laid prone for conventional simulation and CT scans with and without SBDS. The volume of opacified small bowel on CT scans, which was to be included in the radiation fields receiving therapeutic dose, was measured using Picture archiving and communication system (PACS). Results : The average small bowel volumes with and without SBDS were 176.0ml(5.2-415.6ml) and 185.1ml(54.5-434.2ml), respectively The changes of small bowel volume with SBDS compared to those without SBDS were more than $10\%$ decrease in three, less than 10% decrease in two, less than $10\%$ increase in three, and more than $10\%$ increase in two patients. Conclusion : No significant advantage of using SBDS in post-operative pelvic RT for rectal cancer patients has been shown by small bowel volume measurement using CT scan considering additional effort and time needed for simulation and treatment setup.

Purpose : Treatment of choice for uterine cervix cancer stage IIB is radiotherapy. We analyzed survivals, Prognostic factors, patterns of failure and complications. Materials and Methods : This is a retrospective analysis of 167 patients with stage IIB carcinoma of uterine cervix treated with curative external pelvic and high dose rate intracavitary radiotherapy at the Department of Therapeutic Radiology, Soonchunhyang University Hospital from August 1985 to August 1994. All the patients followed up from 3 to 141 months(mean 60 months) and age of patients ranged from 31 to 78 years at presentation(mean : 55 years). Results : Overall complete response rate was $84\%$. The response rate for squamous cell carcimoma and adenocarcinoma were $86\%$ and $60\%$, respectively. Overall 5-years survival rate and disease free survival rate was 62 and $59\%$, respectively Mass size and treatment response were significant Prognostic factors for survival Pathologic type and parametrial involvement were marginally significants Prognostic factors. Local failure was 43 cases, distant metastasis was 14 cases and local failure plus distant metastasis was 3 cases, and most of local failures occurred within 24 months, distant metastasis within 12 months after treatment Twenty eight($16.8\%$) patients developed late rectal and urinary complications There were tendency to increasing severity and frequency according to increased fractional dose and total(rectal and bladder) dose. Conclusions : Survival rate was significantly related to tumor size and radiotherapy response. Tumor size should be considered in the clinical s1aging. To increased survival and local control, clinical trials such as decreasing duration of radiotherapy or addition of chemotherapy is needed. To detect early recurrence, regular follow up after RT is important. Because total rectal and bladder dose affected late complications. meticulous vaginal packing is needed to optimize dose of normal tissues and to decrease late complications.
