This study had done to find an easily-dyeing method for novices because the dyeing method of traditional indigo has not been general to the public so that only an expert could dye the fibers. The results are as the following. When the powders after burning the shell of cockle (tegillarca granosa) were added. pH of the solution was 12.35 The k/s value of 2.49 was the highest in the dye after dipping in the solution of indigo for 1-2 days and the k/s value was 3.10 when adding 20 g/l of the starch (55% corn-starchy products in Korean market) into the solution of indigo. In addtion, the k/s value was the highest when fermenting temperature was $30^{\circ}C$ and when the powders after burning the cockle shell were 4 g/l. There were no differences between water and lye of rice straw which had used for the ferment of indigo. The components of two dye which has traditionally made of the cockle shell and which has made of calcium hydroxide were all the same.

Scirpus L. s.l. of Cyperaceae has been regarded as a monophyletic group, but the taxa of Scirpus s.l. were rearranged into the five independent genera in recent molecular phylogenetic research: Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers. In this study, we examined the morphological characteristics and presented the delineation of the five genera of Scirpus s.l., including 21 taxa from South Korea. As a result of our investigation and analysis of domestic collections and those from abroad, the each taxon could be identified using key characteristics of the rhizome features; a cross-section of culm; the degree of development and the width of leaves; the shapes of the membranous region of leaf sheath; and the shapes and size of inflorescence, bract, floral scale, and achene. These major characteristics are illustrated and artificial keys are suggested in this study. In addition, we suggest a new combination for an unrecorded taxon of Schoenoplectiella that was discovered in Gangwon-do, Goseong-gun and give it the Korean name, as 'a-do-song-i-go-raeng-i'.

The effect of water extract from Cnidii Rhizoma (CRW) on proliferation of human breast cancer cells, nitric oxide production, nitric oxide synthase expression, and ornithine decarboxylase activity was tested. CRW inhibited the growth of both estrogen-dependent MCF-7 and estrogen-independent MDA-MB-23I human breast cancer cells. Lipopolysaccharide-induced nitric oxide (NO) production was significantly reduced by CRW at the concentration of 0.5, 1.0 and 5.0 mg/ml. Expression of inducible nitric oxide synthase (iNOS) was also suppressed with the treatment of CRW in Raw 264.7 cells. CRW inhibited induction of ornithine decarboxylase by 12-0-tetradecanoylphorbol-13-acetate, a key enzyme of polyamine biosynthesis, which is enhanced in tumour promotion. Therefore, CRW is worth further investigation with respect to breast cancer chemoprevention or therapy.

Between Dec. 1958 and Oct. 1989, we had been experienced 14 cases of the esophageal corrosion carcinoma among 562 cases of corrosive esophageal stricture, which incidence was revealed 5.6 % of total esophageal carcinoma cases and 2.5 9o of total benign esophageal stricture cases. The age distribution was from 15 to 64 years, and the mean age was 45.6 years. Ten of the patients were women. The caustic agents were lye in 12 patients and hydrochloric acid in 2 patients. The latent time from injury to the development of carcinoma was from 12 years to 45 years, and the mean latent time was 29 years. In majority of cases, the developing site of carcinoma was just or just above the benign stricture portion of the esophagus. Corrective surgery were made in seven cases; three cases were made esophagectomy and esophagogastrostomy, and the other four cases were made esophagectomy and colon interposition. Palliative surgery including feeding gastrostomy were made in seven cases. All cases had a longstanding history of difficult oral swallowing especially at the site of stricture. We think chronic food irritations of stricture portion of the esophagus induced the development of corrosion carcinoma. In conclusion, we had to suspect possibility of carcinoma in patient with long standing history of benign esophageal stricture. So we recommended preoperative esophagoscopic biopsy in such cases.

This study was conducted to identify instructor's experience on simulation education. The subjects were nine instructors in simulation education of EMT students. Data were collected through documents and in-depth interview from participants. It was analyzed by phenomenological method, using Colaizzi's method. The results of this study were as a follows. From the protocol, significant statements were organized into formulated meanings. The formulated meanings were identified 28 themes, 9 theme clusters, and 4 categories. The 4 categories were as follows; discomfort of forming the learning environment; burden of instructor's role; difficulty from insufficient education condition; possibility of new education. This study suggested that improvement of simulation education can be accomplished by providing opportunities to learn the simulation technology, using the pre-programmed scenarios, having technical support from specialist or additional operator, and adjusting the current paramedic curriculum.

Korea may have the social environment that has a high interest and demand for the fashion industry, but the relative importance that the Hanbok industry occupies in the fashion industry is very low. It can be found that this is attributed to the difficulty in identifying the trends of Hanbok due to the smallness of Hanbok material producers and Hanbok producers, a change in consumers' consciousness of Hanbok, the difficulty of ties and integration between Hanbok-related organizations, the lack of support from government and the like. Given the recent trend that the principal factor that enables the Korean fashion industry to be competitive in the world fashion business community is based on the beauty of Hanbok, this indifference to the Korean Hanbok industry would be the roadblock to internationalizing the Korean fashion industry. Accordingly, this study attempted to identify the problem of Hanbok-rela1ed department as the basic work for the development of the Hanbok industry and present the plan to activate it, thereby providing basic materials for exploiting the new arena of the Hanbok cultural industry the domestic and foreign fashion market in the 21st century.

H.S. Lee, M.D., H.S. Yu, M.D. Esophageal perforation occurred rarely but often lead to a high mortality and morbidity. In the past, the main cause of esophageal perforation in Korea were instrumental perforation in patient with lye stricture of the esophagus. We experienced 9 cases of other forms of esophageal perforation from 1972 through 1977 and obtained the following results. 1. These 9 patients ranged from 10 months to 40 years in age at the time of admission. Six were women. 2. Causes of perforation are instrumental perforation in 3, foreign body perforation in 3, spontaneous perforation in 3 and one pneumatic esophageal perforation. 3. Perforation developed in a variety of locations in the esophagus. Three occurred in cervical part, two in the upper thoracic part, two in the lower thoracic part. 4. The main clinical symptoms and signs were dyspnea, subcutaneous emphysema, chest pain and fever. 5. Thoracic rentgenogram disclosed subcutaneous and mediastinal emphysema, widening of mediastinum and pleural effusion at the time of admission. 6. Complications of esophageal perforation were mediastinitis [7 cases], empyema [4 case], respiratory distress [4 cases] and sepsis [3 cases]. 7. In 3 deaths of the nine patients who sustained perforation of the esophagus, one was due to transfusion of infected blood and two of them were due to sepsis following empyema and mediastinitis. Early treatment [less than 24 hr] gave no hospital death, and good results obtained in the perforations of cervical and upper thoracic esophagus.

Purpose: The purpose of this study was to develop a scenario and evaluate the performance of paramedic students in head trauma simulation education. Method: This study selected a refined head trauma scenario that was developed by graduate students during class from september to November, 2010. Evaluation on implementation of head trauma simulation was conducted on seventeen paramedic students divided into four groups during November, 2010. Results: 1. The head trauma scenario was developed according to the patient assessment for approximately 10 minutes. It contained scene size-up, initial assessment and intervention, rapid trauma assessment and intervention, and decision of transfer. 2. The average time turned out to be 9 min and 36 sec after simulation learning. Total mean score in simulation performance was 2.20, the highest score was 2.44 in initial assessment and intervention, and the lowest score was 1.5 in decision of transfer. 3. Confidence mean was high with the score of 1.0. Conclusion: The finding of this study demonstrate that the simulation education can improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective paramedic education strategy and simulation learning is needed for further development of various scenarios.

Purpose: The purpose of this study is to provide basic data to improve prehospital emergency care for patients with labor pain, vaginal bleeding and rape experience by analyzing the reports of 119 emergency medical technicians. Methods: Data were prehospital reports of 190 patients having chief complaints of labor pain, vaginal bleeding and rape in Chungcheongnam-do from January 1, 2012 to December 31, 2012. Data were analyzed using SPSS 21.0 descriptive statistics and $x^2$-test. Results: From the 190 cases of labor pain, vaginal bleeding and rape, labor pain accounted for 57.9% including 75.5% of normal delivery; vaginal bleeding accounted for 35.8% including 26.5% of postpartum hemorrhage; and rape victims accounted for 6.3%. Cases with more than one vital sign accounted for 94.2%, but cases without primary assessment of the obstetrics and gynaecology accounted for 38.4% from gestation weeks, 78.0% from parity, and 87.4% from history taking relating to event. Patient care including emotional support was the first priority care accounted for 78.4% and 60% of care was keeping the patients warm. Conclusion : In order to handle various emergency situations properly, the records must be supplemented by obstetrical and gynaecological rape checklist and rape victims supporting system should be established.
