神話 · 文學의 理論考察

Herman Broch가 20세기를 “the Mythical Age"라 명명했던 것은 금세기의 많은 작가와 비평가들이 신화적인 것에 몰두해 있다는 데서였다. 신화가 많은 문학의 특히 많은 현대문학의 소재가 되어있으며, 또 그 모습이 Proteus신만큼 갖가지일 뿐만이 아니라 ”신화적“이란 수식어 역시 다양한 문화적 현상을 내포한 말로 쓰이고 있어서 그 정체 파악이 어려운 신화는 19세기 학자들이 흔히 ”fable", "invention", "fiction"의 뜻으로 여겼고 이와는 달리 20세기 전반의 신화연구자들은 고대사회에서 이해되었던 바와 같이 “true story"로 보았다. 나아가서 현대적 의미의 신화는 전통적 신화개념을 벗어나 거의 모든 상상력의 산물을 가리키는 말로 쓰이게 되어 현대적 의미혼란을 가져왔다. 그래서 신화의 정의는 심지어 대립되는 견해까지 포용하는 ”both broad and loose"한 것이어야 한다고 Mark Schorer는 주장 한 바 있다. 바꾸어 말해 전통적 신화관과 현대적 신화의미를 포괄할 수 있는 신화정의가 되기 위해서는 근래의 인류학자들이 제창한 정확한 정의부여는 물론, 고대희랍인들에 의해 시작되었던 여러 가지 신화해석을 포함하는 것이어야 한다.

A gallium based alloy(GA) that was developed as a substitute for dental amalgam was investigated for electrochemical corrosion behavior in 4 kinds of electrolytes(1% lactic acid, 0.05% HCI, Modified Fusayama's artificial saliva, and 0.9% NaCl). The related corroded microstructure were examined and microanalyses were conducted using ICPES. Polarization tests were conducted by scanning from -1,500㎷ to 1,000㎷(vs.SCE) at 75㎷/min. The obtained results were as follows: 1. GA showed wide passivation area next to SYB in artificial saliva, suggesting good stability. 2. The amounts of Sn, Cu released from GA were similiar to those of CAV, and decreased in the order of KAT, SYB. 3. All of specimens were observed pits at the area of pores in electrolytes containing chloride ions, and forming much corrosion products in 1% lactic acid and artificial saliva after corrosion test. 4. From the surface analyses of XRD, GA showed much corosion products containing gallium at the surface after corrosion test. In conclusion, the corrosion resistance of GA was lower than that of SYB and similiar to that of CAV and KAT.

There were no specific effects for test materials on Sprague-Dawley (S.D.) rats in clinical symptoms, amounts of food intakes, weight changes, laboratory findings, and pathology after whole body l, l-Dichloro-1 -fluoroethane (used as coolant, metal cleaner and solvents) exposure(0, 1,500, 3,000, and 6,000 ppm) for 13 weeks (6 hour/day, 5 days/week). However, the loss of capillary vessels in eyeball (pupil) was observed in a female rat among 6,000 ppm group. Though there was a tendency for MCHC (Mean Corpuscular Hemoglobin Concentration) in rat to be decreased (p<0.05), it was not regarded as abnormal because the values were within normal limits. In asthma-stimulation related evaluations, there was also a tendency for inflammatory cell counts in bronchoalveolar lavages to be increased. But it had no statistical significance, and also no dependency on sex and the exposed concentration. Based on this result, the non observed effect level (NOEL) induced by 1, 1-Dichloro-l -fluoroethene inhalation was evaluated in groups with 3,000 ppm below (S .D. Rats, 13 weeks). Finally, it was concluded that the short term exposal of 1, 1-Dichloro-l-fluoroethane is not considered as a asthma stimulant by inhalation despite of some study limitations such as test animals use and short-term exposure .

Clinical Significance of Acute Vessel Shrinkage below the Stent after Vein Angioplasty in a Patient with May-Thurner Syndrome

Sang Sun Lee,Won Yu Kang,Dong In Nam,Il Hyung Jung,Chung Kang,Hong Ju An,Ho Yeong Song,Hoon Kang,Sang Cheol Cho,Sun Ho Hwang,Wan Kim 조선대학교 의학연구소 2014 The Medical Journal of Chosun University Vol.39 No.2

May-Thurner syndrome is associated with deep vein thrombosis resulting from chronic compression of the iliac vein against the lumbar vertebrae caused by the overlying common iliac artery. Stent insertion into the compressed lesion is used in treatment of May-Thurner syndrome. Various complications can occur during angioplasty while using a stent. Among these complications, shrinkage of the vein below the stent, a rare complication, was observed in our hospital during treatment of a patient with May-Thurner syndrome. Different complications can occur when venous angioplasty is performed, unlike that when arterial angioplasty is performed.

Purpose: The safety of online contouring and planning for adaptive radiotherapy is unknown. This study aimed to evaluate the dosimetric difference of the organ-at-risk (OAR) according to the extent of contouring in stereotactic magnetic resonance image-guided adaptive RT (SMART) for pancreatic cancer. Materials and Methods: We reviewed the treatment plan data used for SMART in patients with pancreatic cancer. For the online contouring and planning, OARs within 2 cm from the planning target volume (PTV) in the craniocaudal direction were re-controlled daily at the attending physician's discretion. The entire OARs were re-contoured retrospectively for data analysis. We termed the two contouring methods the Rough OAR and the Full OAR, respectively. The proportion of dose constraint violation and other dosimetric parameters was analyzed. Results: Nineteen patients with 94 fractions of SMART were included in the analysis. The dose constraint was violated in 10.6% and 43.6% of the fractions in Rough OAR and Full OAR methods, respectively (p = 0.075). Patients with a large tumor, a short distance from gross tumor volume (GTV) to OAR, and a tumor in the body or tail were associated with more occult dose constraint violations—large tumor (p = 0.027), short distance from GTV to OAR (p = 0.061), tumor in body or tail (p = 0.054). No dose constraint violation occurred outside 2 cm from the PTV. Conclusion: More occult dose constraint violations can be found by the Full OAR method in patients with pancreatic cancer with some clinical factors in the online re-planning for SMART. Re-contouring all the OARs would be helpful to detect occult dose constraint violations in SMART planning. Since the dosimetric profile of SMART cannot be represented by a single fraction, patient selection for the Full OAR method should be weighted between the clinical usefulness and the time and workforce required.

Successful Intravascular Ultrasound Guided Treatment of May-Thurner Syndrome with Prominent Collateral Vein and Latent Thrombus

Hoon Kang,Jung Il Hyung,Chung Kang,Dong In Nam,Sang Sun Lee,Hong Ju An,Ho Yeong Song,Sang Cheol Cho,Won Yu Kang,Sun Ho Hwang,Wan Kim 조선대학교 의학연구소 2014 The Medical Journal of Chosun University Vol.39 No.2

May-Thurner syndrome is caused by blockade of local venous flow due to local vascular intimal proliferation, caused by repeated pulsatile compression of the iliac or iliofemoral vein between the iliac artery and the lumbar spine. In this case, we confirmed May-Thurner syndrome using lower extremity computed tomographic angiography and venography. However, on venography, it was impossible to distinguish the left iliac vein from the collateral vein; a thrombus was also seen, although some of the thrombus was not seen clearly. These problems were overcome with use of intravascular ultrasound. We report on intravascular ultrasound guided treatment of May-Thurner syndrome.

The quantitative accuracy of dry rehydratable film method was compared with the standard culture method to analyze the applicability of dry rehydratable film in the total aerobic bacteria test for water. The materials used in this study were 500 cases of water and were tested according to the Korean official test method for drinking water. The mean value of the total aerobic bacteria in plate count agar(PCA) and MC-Media Pad AC(MAC) were 2.6 ± 1.1 Log cfu/mL and 2.6 ± 1.2 Log cfu/mL. The p value and correlation coefficient(R²) were 0.933 and 0.9985 between the PCA and MAC, respectively, indicating no significant difference and very high correlation. According to the water types, the p value and R² were 0.887 and 0.9911 in the PCA and MAC. In the purified water, the p value was 0.973 and R² was 0.9934 in the PCA and MAC of other water. In each type of water, there were no significant differences between the PCA and MAC, and the correlation was very high. Thus, it is suggested that the MAC would be available for total aerobic bacteria test for water.
