This study had been conducted to investigate the effect of some plant growth regulators inducing fruit enlargement and optimal harvest time in Sageretia thea. Two hundred fifty $mg/{\ell}$ mepiquat chloride treatment, $1mg/{\ell}$ thidiazuron treatment on full bloom, and $200mg/{\ell}$ gibberellic acid treatment on 7 days before full bloom resulted in the increase of 21.7% in weight, and $200mg/{\ell}$ gibberellic acid treatment 7 days before full bloom, 10$mg/{\ell}$ forchlorfenuron treatment 14 days after full bloom, and $1mg/{\ell}$ thidiazuron treatment on full bloom also brought about positive effects on the enlargement of the fruit, increasing 6.3%, 6.3% and 8.1% in its transverse diameter, respectively. Furthermore, the effects of the plant growth regulator treatments on the harvest time of Sageretia thea were determined as follows: the increase in the optimal harvest time of 57.2 - 75.4%, shorter maturation period, by the treatments with $500mg/{\ell}$ mepiquat chloride 7 days after full bloom, $100mg/{\ell}$ gibberellic acid treatment on full bloom, $2.5mg/{\ell}$ forchlorofenuron 7 days after full bloom and $2mg/{\ell}$ thidiazuron treatment 7 days before full bloom; and the greater effects of plant growth regulator treatments on the fruit maturation in the following order, gibberellic acid > thidiazuron > forchlorofenuron > mepiquat chloride. The results of this study are expected to be used as a reference data to develop Sageretia thea as a new local specific crop for Jeju island.

Carotid-cavernous fistula (CCF) is a rare condition. However, it should be suspected when there are traumatic facial fractures, because if not diagnosed, it can lead to permanent damage such as blindness. Traumatic CCF often presents delayed symptoms, and delayed diagnosis without prompt treatment can lead to permanent injuries in optic and cranial nerves III, IV, V, and VI as well as intracranial hemorrhage. The routine initial modality for patients with suspected facial bone fractures is noncontrast computed tomography (CT) to identify any fracture lines and check for intracranial hemorrhage. We report a post-traumatic CCF case with a 4-day symptom delay, where left superior ophthalmic vein (SOV) enlargement was observed on the routine noncontrast facial CT with ipsilateral orbital wall fracture. When the patient first presented to the emergency room (ER), we did not detect vein enlargement on CT. Afterwards, the patient developed delayed symptoms of CCF and was readmitted to the ER. When we reanalyzed the first CT scan, an enlarged SOV was confirmed. The diagnosis was confirmed via magnetic resonance imaging angiography, and the patient was successfully treated with embolization of the fistula. Thus, we recommend reviewing ophthalmic vein enlargement that is readily identifiable through noncontrast CT for patients injured by craniofacial trauma to suspect the presence of delayed CCF at their initial presentation.

이 연구는 '우렁각시 설화'에 나타나는 '결연형'의 증가 양상과 세속화 양상을 분석하였다. "한국구비문학대계"(1979-1985)와 그 후속 작업인 '한국구비문학대계 개정 증보 사업'(2008-2018)에서 채록된 '우렁각시 설화' 71편의 유형을 분석하고, 결연형을 중심으로 세속화 양상을 관찰하였다. '우렁각시 설화'에 관한 자료를, "대계"를 기준으로 1910-70년대 자료와 1980년대 이후의 자료로 나누었다. 80년대 이후 "대계"와 '개정 증보 사업'의 자료에서는 결연형(단순형, 복합형)이 증가하는 추세를 보이고 있다. 결연형은 "대계"와 '개정 증보 사업'에서 채록한 '우렁각시 설화'의 60%를 차지하고 있으며, 이별형(34%)의 2배에 가까운 수치를 보여준다. 우렁각시 설화의 결연형에서는 '금기 화소'가 사라지고, 금기 화소가 제시되더라도 금기 파기형보다는 금기 순응형이 더 많이 나타났다. 이는 파기됨으로써 신성혼의 의미를 강조하는 '금기'의 기능이 약해졌음을 의미하는 것이다. 오히려 '금기'에 순응함으로써 남녀 결연을 이루고자 하는 인식이 나타난다. 우렁각시의 탈신성화에 따라 우렁각시와 총각의 결연은 평범한 남녀의 결연으로 인식되는 경향이 있다. 금기 화소가 제시되지 않는 결연형의 증가와 남녀 결연을 중심으로 서사가 전개되는 '지하국 대적 퇴치형'의 등장 양상은 우렁각시 설화의 세속화 양상과 연계되는 것으로 볼 수 있다. 현실 중심의 세계관이 반영됨에 따라 신성시 되는 존재에 대한 관심과 인식이 사라지고, 현실 세계에서의 남녀의 결연을 통해 행복한 결말을 추구하는 의식이 엿보인다. 이 논문은 2010년대 '개정 증보 사업'에서 채록된 '우렁각시 설화' 37편을 연구대상에 포함시켰다는 의의가 있다. '개정 증보 사업'에서는 남녀 결연담으로서 성격이 짙은 '지하국 대적 퇴치형'도 새로이 관찰된다.

This study was performed to investigate the effects of isolated soyprotein and salt (NaCl) restriction on the serum lipid and the kidney functions of streptozotocin-induced diabetic rats. Sprague-Dawley males of normal and streptozotocin-induced diabetic rats were raised for 6 weeds divided into 4 groups each according to protein sources and salt levels. The sources of protein were isolated soyprotein and casein. Salt levels tested were 0.1% (normal) and 0.01% (low). The results are summarized as fellows: kidney weight, blood glucose, hemoglobinAlc, GFR and urinary protein of diabetic groups were higher than those of normal groups. Isolated soyprotein lowered total lipids, triglycerides, and total cholesterol in serum and plasma angiotensin II concentration as well as alleviated kidney enlargement and GFR in diabetic rats. Salt restriction didn\\`t affect serum lipid level but decreased GFR and increased angiotensin If concentration. In conclusion, isolated soyprotein decreased serum lipids, plasma angiotensin II concentration, sidney enlargement and GFR, while salt restriction increased plasma angiotensin II concentration. The results suggest that isolated soyprotein and salt restriction seem to cause different effects on plasma angiotensin II concentration and that isolated soyprotein might be of value in the prevention of diabetic artherosclerosis and diabetic hypertension.

This study was performed to evaluate the ultrasonographic findings of ethylene glycol intoxication. Ten healthy mongrel dogs which was administered with ethylene glycol, were evaluated in terms of clinical findings, hematological findings, blood chemistry, and ultrasonographic and histopathological findings of kidney. The results obtained through these experiment could be summarized as follows : 1. Typical clinical symptoms such as vomiting, initial apprehension, depression, thirst, dehydration, tremor, anorexia, hematuria, anuria, weakness, weight loss, flaccid paralysis, tachypnea, coma, and death, were revealed after administration of ethylene glycol. 2. Special symptom of bloody diarrhea was occurred by administration of ethylene glycol. 3. After administration of ethylene glycol, PCV was decreased continuously(p<0.01), and total leukocyte count was increased gradually, revealed the highest value at day 5 and thereafter decreased. 4. Remarkable changes of ultrasonographic findings such as high echo intensity of renal parenchyma and emergence of halo in corticomedullary junction, were revealed after administration of ethylene glycol. Early(hour 8) enlargement and late(day 3) enlargement were observed in kidney(p<0.01). Especially, late enlargement was observed concurrently with the elevation of BUN and creatinine values. 5. Calcium oxalate crystals, metabolites of ethylene glycol, were observed in histopathologic findings of kidney. Also, degeneration and necrotic exfoliation of epithelial cells were recognized in addtion to swelling of renal tubules.

This study provides basic data to develop a brassiere pattern that can cover the big breast of breast enlargement patients. In this study, we also showed areas of the brassiere cup pattern and the body surface of the breast on a breast enlargement patient. The results of the study are as follows. Correlation analysis was obtained between volume and body surface area and breast detail dimensions. After the correction process, we proposed a research bra pattern for breast augmentation patients. The cup-boundary in bra patterns of breast enlargement surgery patients is longer than the bra patterns of the general breast; therefore, the height of the inner and outer edges of the upper cups is higher. Also, it is necessary to set the new breast upper point when measuring the upper length in patients with breast augmentation surgery because the points of circumference of the breast are marked higher than chest circumference.

In this study, compressive strength and adhesion strength were measured as repair materials to evaluate the mechanical and electrical properties of compression and shear specimens with self-sensing repair materials. As a result of the experiment, the strength improvement rate of the compression test specimen was higher than the section enlargement area ratio, but the shear test specimen did not show an improvement in strength as much as the section enlargement area ratio. Compression experiments under load showed high correlation between FCR-Strain and FCR-Stress, confirming self-sensing performance. However, the shear test did not show as much correlation as the compression test. Accordingly, it is judged that the self-sensing repair material is suitable for the compression member on which the compression load acts in the building.
