This study analyzed characteristics of natural and human environments in Gyeongju's Seochun and Namchun Liver, and suggested nature-friendly planning strategies for self-purification of water quality, biodiversity improvement and conservative waterfront recreation. The environmental analysis included streambed structures, floodplain soils, water quality, vegetation, wildlife, and human facilities. Nature-friendly planning strategies were established based on analysis of the environmental characteristics. They focused on not merely spatial zoning and layout divided into four zones-preservation, partial preservation, conservation, and use, but close-to-nature channel revetment techniques, natural water-purification facilities, biotope diversification, and water-friendly recreation and circulation. Strategies pursued both renewal of stream naturalness and hydraulic stability of streamflow by minimizing transformation of natural channel micro-topography and biotope, and by reflecting natural traces of streambed structures such as revetment scour and sedimentation.

A Case of Pulmonary Thromboembolism Complicating Acute Overdose of Benzodiazepines

최재영,정진우 대한응급의학회 2014 大韓應急醫學會誌 Vol.25 No.2

Acute pulmonary thromboembolism (PTE) is a major medicalproblem in many hospitalized patients with medical andsurgical conditions, and venous thromboembolism isresponsible for up to 15% of all in-hospital deaths. However, PTE complicating acute intoxication has beenreported only rarely, and prophylaxis for venous thromboembolismis not routinely incorporated into the managementof acute poisoning in emergency departments or generalwards. We describe here a case of pulmonary thromboembolismthat developed within 48 h of acute benzodiazepineoverdose. A 47-year-old female patient was brought to the emergencydepartment by ambulance. She had been found unconscious,and empty packages of medications prescribed byher psychiatrist and an empty bottle of liquor were found. The estimated drugs and amounts were alprazolam 22.5mg, diazepam 150 mg, flunitrazepam 7.5 mg, fluoxetine150 mg, and propranolol 600 mg. Approximately 40 hoursafter initial presentation, she complained of dyspnea andpulse oxymetry indicated 84%. Her arterial pH was 7.41,pCO2 41.6 mmHg, pO2 46.8 mmHg, and oxyhemoglobinsaturation was 83.4%. The serum D-dimer concentrationwas 2.78 mcg/dL, and computed tomography of the chestshowed acute PTE in the right upper lobar and segmentalpulmonary arteries and both lower segmental pulmonaryarteries. When caring for patients with sedative drug overdose, a highlevel of suspicion of PTE is required, and appropriate diagnosticand therapeutic measures might be undertaken whenPTE is suspected. In addition, appropriate prophylaxis forvenous thrombosis should be considered.

Lindera obtusiloba 꽃 발효 추출물의 항산화 및 미백 효과

최재영,이성재,조영재,이자복 국제차세대융합기술학회 2023 차세대융합기술학회논문지 Vol.7 No.9

본 연구는 생강나무(Lindera obtusiloba) 꽃 발효 추출물의 항산화능을 평가하고, 발효 최적화를 실시한뒤, 이를 바탕으로 미백 활성 측정을 진행하였다. DPPH assay에서는 발효 24시간 후 1개의 균주가 항산화능을증가시켰으며, ABTS assay에서는 발효 24시간 후 3개 균주가 항산화능을 증가시켰다. TPC assay에서는 발효24시간 후 3개의 균주 샘플에서 페놀성 물질의 추출량이 증가함을 보였으며, TFC assay에서는 발효 24시간 후샘플 중 3개의 균주 샘플에서 플라보노이드의 추출량이 증가함을 보였다. 미백 활성도를 측정하기 위해 B16F10을이용한 세포 실험을 진행하였다. 생강나무 꽃 발효 추출물의 세포 독성은 12.5-100 μg/mL에서 나타내지 않았으며, 생강나무 꽃 발효 추출물을 100 μg/mL에서 34.7±0.9%의 멜라닌 생성 억제 효과를 나타내었으며 34.2±1.8% 의 tyrosinase 생성 억제 효과를 나타내었으며, 발효 전과 비교하여 통계적으로 유의미한 차이를 보였다(p<0.05). 이를 바탕으로 생강나무 꽃의 발효는 미백 효과를 상승시킬 수 있음을 확인하였다. This study evaluated the antioxidant and skin-whitening activity of fermented Lindera obtusiloba flower extracts and optimized the fermentation process. First, the antioxidant capacity was measured. In the DPPH assay, one strain increased the antioxidant capacity after 24 h of fermentation, and in the ABTS assay, three strains increased the antioxidant capacity after 24 h of fermentation. The TPC and TFC assays both revealed an increase in the extraction of phenolic compounds in three strains after 24 h of fermentation. Then, experiments using B16F10 cells were conducted to determine the whitening activity. No cytotoxicity was observed for the fermented flower extract in the concentration range of 12.5–100 μg/mL. Meanwhile, treatment with the fermented extract at 100 μg/mL resulted in a 34.7 ± 0.9% reduction in melanin production and a 34.2 ± 1.8% reduction in tyrosinase production versus the values before fermentation (both p<0.05). Thus, the results confirmed that fermentation of L. obtusiloba flowers can enhance their whitening effect.

1. Background and Purpose: We intended to make the standards of CVA management of Sasang Constitutional Medicine and be helpful to understand the constitutional symptoms through a clinical study of CVA. 2. Methods: We studied 157 CVA inpatients(79 men and 78 women) who were in constitutional clinic of Dongguk Pundang Oriental Hospital during 1 year from March 1997 to February 1998. We investigated and analysed the characteristics, past histories, symptoms and progresses of patients. 3. Results: The results of constitutional analysis showed 88 Taeumin(56.1%), 48 Soyangin(30.6%) and 21 Soeumin(13.4%). The frequency of strokes was much the same between male and female and the greater part of cases were 50-70 of age. The CVA cases were classified into 119 cerebral infarction(75.8%), 11 cerebral hemorrhage(7.0%), 1 subarachnoid hemorrhage(0.6%) and 26 trasient ischemic attack. From the standards of symptom management, there were abnormality of a coated tongue(63.1%) in most cases, sleeping disorders(48.4%), excremental disorders(44.7%) and urinary disorders(36.9%) on admission. With regard to the rate of improvement in the standards of CVA management, excremental disorders improved 87.1% and emotional disorder 81.0%, swallowing disorder 78.7% and so on.

The influence of solidification rates on the morphology and distribution of δ-ferrite and eutectic niobium carbides was studied using Bridgman-type unidirectional solidification apparatus in order to simulate the solidification pattern of a large-scale ingot of 12% chromium rotor steel. The volume fractions of the δ ferrite contained in the specimens solidified with the withdrawal speeds of 225 ㎜/hr, 45 ㎜/hr, and 4.5 ㎜/hr were measured to be 7%, 5%, and 30% respectively. δ-ferrite was finely distributed in the case of the withdrawal speeds of 225 ㎜/hr and 45 ㎜/hr, but the distribution was coarse network type in the case of the withdrawal speed of 4.5 ㎜/hr. When hot compressive working was applied in temperatures from 950℃ to 1250℃, 3-ferrite was transformed into carbides and austenite at the interface of δ-ferrite with the matrix. Subsequent heat treat melts result in a complete annihilation of δ-ferrite in the case of fast withdrawal speeds, but result in only a partial annihilation in the ca -e of the slow withdrawal speed, 4.5 ㎜/hr.
