This study focuses on Korea films of historical communication. Narrative analysis was conducted on the films in 2000s including , and <26 Years> that mainly have dealt with the 'Gwangju Democratization Movement'. As a result of the syntagmatic analysis, these films try to stabilize 'social imbalances' in the aspect of individuals and conceals issues of social structure. In addition, the result of paradigmatic analysis reveals that textual factors of 'active involvement of female characters', 'continuity of history through the survivors' demonstrate its strategies to publicize the historical truth. Consequently these films show its limitations that weakens historical meaning by placing unsolved problems of social structure as well as the love story. But rather than describing it as a history of the past, these films act as a catalyst to bring thins specific historical issue to our present lives and publicize it as a current issue. Therefore, the historical film not only allows current generation to remind to history but also to provide an opportunity to publicize the important issues of social structure in the present society.

Background: Dissection flaps in acute type A aortic dissection typically extend into the root, most frequently into the non-coronary sinus (NCS). The weakened root can be susceptible not only to surgical trauma, but also to future dilatation because of its thinner layers. Herein, we describe a new technique that we named the "neo-adventitia" technique to strengthen the weakened aortic root. Methods: From 2012 to 2016, 27 patients with acute type A aortic dissection underwent supracommissural graft replacement using our neo-adventitia technique. After we applied biologic glue between the dissected layers, we wrapped the entire NCS and the partial left and right coronary sinuses on the outside using a rectangular Dacron tube graft that served as neo-adventitia to reinforce the dissected weakened wall. Then, fixation with subannular stitches stabilized the annulus of the NCS. Results: There were 4 cases of operative mortality, but all survivors were discharged with aortic regurgitation (AR) classified as mild or less. Follow-up echocardiograms were performed in 10 patients. Of these, 9 showed mild or less AR, and 1 had moderate AR without root dilatation. There were no significant differences in the size of the aortic annulus (p=0.57) or root (p=0.10) between before discharge and the last follow-up echocardiograms, and no reoperations on the aortic roots were required during the follow-up period. Conclusion: This technique is easy and efficient for reinforcing and stabilizing weakened roots. Furthermore, this technique may be an alternative for restoring and maintaining the geometry of the aortic root. An externally reinforced NCS could be expected to resist future dilatation.

In order to take cue of the dying persons and their survivors in a more positive and affirmative atti-tube. and to understand the valuable meaning of and dying. a survey was performed to 550 cases of health care personnels including 116 nursing students. 238 medical students. 137 nurses. and 59 doctors. Samplings were made through census Procedure from the entire group of medical and nursing students in College of Medicine. Chung-Ang University. and of licenced nurses and doctors in Chung-Ang University Hospital. and in Han-Gang Sacred Heart Hospital from the first to the end of march. 1980. These collected data were computerized at KIST by SPSS programming and were statistically analyzed by chi-square test. Through content analysis of the word associated with death and descriptive analysis of the death-re-lated variables. the following conclusion in is reached. First. Total numbers of death-word percieved by health care personnels were 198 kinds. Among them, 40 kinds of words associated with death were responded from than 1% of the total. As to the 10 death related word responded by free word association method. it was revealed that individual average number of death related word was 7.70 word. which came from higher number of words in the senior students (8.96 word) or the graduates (8.10 word) compared with the freshman (6.84 word). Second. In Content specific analysis of the death related word. more frequently perceived types summarized as the following order; the affective context of death. the diseases. the disasters. the religion, the funeral ceremonies. the separation, the drakness. and the life. Third. The most prevalent 10 words associated with death which the the respondents gave response to the the first recalling word. were as following o order； the dieases. the sadness, the vanity. the darkness, the frustration. the suicide. the incurable dieases, the graves. the dead. and the catastrophes. By sex, the diease is outstanding in females, but the vanity is in males. By occupation. the vanity and the dead was frequently observed in student group including senior students. while the incurable dieases presented by doctors. Fourth. In health care personnels. the first perceived ages of death were 11.47 $\pm$3.33 years (8.14- 15.80 years). Among them. senior students were inclined to percept death at the earliest age of life (11.28years). while doctors and nurses perceived death later in their life (12.98 years). Fifth, It is revealed in this survey that the most frequently responded death perceiving motives by health care personnels ar“psychological conflict”and“death of those around them”. Death perceiving motives can be classified in two factors; personality and life circumstances. Sixth It is of interest that only 11.3% health care personnels was found to feel death as inevitable or acceptable event. whereas 58.3% deny or reject it.

Objectives & Methods : To obtain the 50% lethal dose(LD50), approximated lethal dose(ALD) and approximated target organs of 'Mahwangyounpae-tang' for further study into such things as repeated dose toxicity, genotoxicity and reproductive toxicity, single dose toxicity was tested in male SD rats according to KFDA Guideline 1999-61[KFDA, 1999] at dosage levels of 2,000, 1,000, 500, 250 and 125 mg/kg/$10m{\ell}$. In this study, mortalities, clinical signs, body weight changes and body weight gains, gross findings and weight of principal organs were detected during and/or after 14 days of single dosing. Results & Conclusions : After 2 or 3 days of dosing, 1 or 2 animals in 2,000 mg/kg-dosing groups died. Excitation and leaping response were observed as test article-treatment related clinical signs. These abnormal signs were restricted to 2,000 and 1,000 mg/kg-dosing groups and survivors recovered to normal within 3 or 4 days after dosing. Significant decrease in body weight were observed in some periods of observation in 2,000 and 1,000 mg/kg-dosing group, from 1 days after dosing compared to those of vehicle control group. Significantly diminished body weight gains were observed in observation periods in 2,000 and 1,000 mg/kg-dosing group compared to those of vehicle control group. Hypertrophy and hemorrhage of heart and decoloration of kidney were observed as test article-treatment related gross findings. These abnormal findings were restricted to 2,000 and 1,000 mg/kg-dosing groups. A significant increase of absolute and relative heart and kidney weight were demonstrated in 2,000 mg/kg-dosing groups. The value for LD50 found in this study was 2,218.57 mg/kg. ALD in this study was 2,000 mg/kg, and the target organs are considered to be the heart and the kidney.

The authors evaluated 153 patients who had undergone cardiac valve replacement between October 1979 and July 1988. The results are as follows: l. Out of 153 patients, there were 56 males and 97 females ranging from 15 to 62 years of age with a mean of 37 years. 2. Isolated mitral valve replacement took place in 82 patients, aortic valve replacement[AVR] in 16, double valve replacement[DVR] in 34, AVR combined with open mitral commissurotomy in 19, and tricuspid valve replacement[TVR] was done in 2 patients. 3. 153 patients had 187 prosthetic valves replaced with Ionescu-Shiley valves[16], Carpentier-Edwards[36], Bjork-Shiley[19], St. Jude Medical[108], and Duromedics[8]. 4. Our of 98 patients with atrial fibrillation[ 64% of a total 153 patients ] during the preoperative period, 22 patients recovered NSR[ 22/98, NSR recovery rate 22.4%] after valvular surgery and remaining 76 patients revealed persisting atrial fibrillation[76/153, 49.7% ]. 5. Preoperative episodes of systemic arterial embolization were attained in 9 patients[9/153, 6% ], and left atrial thrombi were confirmed in 22 patients intraoperatively[ 22/153, 14% ]. Of these, only one patient, however, demonstrated the correspondence of preoperative embolization and intraoperative existence of LA thrombi. 6. With mechanical prostheses, anticoagulant therapy was begun 48 hours after operation with sodium warfarin[2.5-5.0mg/day], maintaining the prothrombin time between 16 and 18 seconds or 30 to 50% of control values and continued for life. With tissue prostheses, sodium warfarin was continued for 3 to 6 months and converted into buffered ASA[ 325 mg/day ] for one year. 7. The mean follow-up for the survivors was 30.1 months, with a range from 3 months to 9 years. All suspected or confirmed thromboembolic episodes counted as events and occurred in 4 patients[ 1.04%/patient-year] with mechanical valve replacement. No persistent paralysis or death was noted. Late complications have not yet occurred in the patients with isolated MVR and AVR. 8. There were remarkable structural failures of tissue valves in 3 patients[ 1.9%/patient-year ], while no instance of failure of a mechanical valve. 9. There were 10 operative early deaths[10/153, 6.5%] and 5 late deaths[5/153, 3.3%]. Consequently, overall mortality was 9.8%[ 15/153] during follow-up period. 10. We currently favor using the St. Jude Medical valve in all patients requiring valve replacement except in those who can not take warfarin anticoagulation.

Pain is one of the most common and painful symptoms that cancer patients suffer from. Pain seriously affects 30-50% of the patients at the early cancer diagnosis stage or who receive active anticancer treatments, 60-70% of the patients with progressive cancer, and 80-90% of the patients at the late stage of cancer. However, there is no systematic and easy pain control program for the cancer patients. In this study, an algorithm is proposed to provide quick pain relief service upon the occurrence of sudden pain, for the purpose of controlling the sudden pain that cancer operation survivors experience. In developing the algorithm, questionnaires, evaluation forms and National Comprehensive Cancer Network (NCCN) guideline were considered, and a trial service was provided to a group of 20 cancer patients for a month to evaluate the designed algorithm. The results of the trial service were examined by expert medical workers to evaluate the proposed algorithm, and a 90% compatibility decision was derived, which verified the effectiveness of the proposed algorithm. In the case of incompatibility decision, the management of the pain diary did not have compatible results. Therefore, the further study will additionally address the customized pain diary algorithm.

A retrospective study was performed on 15 patients with suprasellar germ cell tumors treated by megavoltage external beam irradiation between Feb. 1979 and Dec. 1985. Follow-up period of survivors was 30 to 91 months. Histologic diagnosis was obtained before radiation therapy in 10patients (9 germinomas and 1 mixed). Five patients were treated without histologic verification. In 9 patients with biopsy-proven germinomas radiation therapy was delivered to the craniospinal axis in 6, to the whole brain in 3. In 5 patients with mixed germ cell tumor or elevated tumor marker, irradiation was delievered to the craniospinal axis in 2, to the whole brain in 2, and to the primary site only in 1. Total doses ranged from 5,000 to 5,500 cGy to the primary site, 3,000 to 4,400 cGy to the whole brain, and 1,300 to 3,000 cGy to the spine. In these 14, local tumor was controlled and primary or spinal failure was not observed. One patient without elevated tumor marker was treated to the whole brain. The tumor was not controlled and he had spinal recurrence. Overall survival and disease-free survival rates were $86\%$ at 5 year. It is proven that radiation therapy is an effective treatment for suprasellar germ cell tumors. The neuroendocrinologic presentation, tumor marker status, early response to radiation measured on CT seem to be useful means for selecting patients for radiation therapy when tissue diagnosis is not available.

Materials and methods: Between 1984 to 1994, 136 patients underwent primary and isolated aortic valve replacement with 79 Carbomedics and 57 St. Jude prostheses. Results: Age ranged from 16 to 67 year(mean : 44.5${\pm}$12.7 years). Statistically significant differences in preoperative clinical characteristics between two groups were not found. There was one early death in the St. Jude group and none in the Carbomedics group. Early prosthetic valve-related complications including death were not significantly different between the two groups(p value= 0.572). One hundred thirty five early survivors were followed for a total of 354.2 patient-years(mean=31.5${\pm}$16 months). In the CarboMedics group, actuarial survial rate at 5 years was 97.1${\pm}$1.9%, and in the St. Jude group, it was 95.9${\pm}$2.8%. In the CarboMedics group, actuarial free rate from all valve-related events at 5 years was 92.1${\pm}$3.1%, and in St. Jude group, it was 89.8${\pm}$5.0%. Conclusion: We conclude that early and late results after performing isolated aortic valve replacement with CarboMedics and St. Jude valve are not significantlly different.

Background: Ventricular septal defect(VSD) is rare but feared complication after acute myocardial infarction. The patient could survive by surgery only, but the surgical mortality is still high. We investigate the surgical result and predictors for early surgical mortality. Material and Method: Between August 1993 and February 2006, 8 patients (male, 2: female, 6) with postinfarct VSD underwent surgical repair. Seven patients had one-vessel disease of left anterior descending artery, and 6 of them had wide extension of infarction to posterior septal wall as well as anterior septal wall of both ventricles. One patient had concomitant coronary bypass grafting to a coronary lesion unrelated to the infarction. Two patients had concomitant tricuspid annuloplasty and 1 patient mitral valvuloplasty. Result: Surgical mortality was 37.5%(3 patients). They all had only one-vessel disease of left anterior descending artery, which made extended posterior septal wall infarction as well as anterior septal wall infarction of both ventricles. In preoperative M-mode echocardiographic study of left ventricle, they had lower ejection fraction than survivors($34.9{\pm}4.2\;vs.\;54.8{\pm}12.3$; p=0.036). Conclusion: Most of patients with postinfarction VSD had one-vessel disease of left anterior descending artery. Early surgical mortality occurred in the patients with poor ejection fraction of left ventricle and the wide anterior septal wall infarction extending to the posterior septum.
