The current design codes discuss the effective compressive strengths of columns, which reflect a decrease in load transfer performance that can occur when columns and slabs have different concrete compressive strengths. The effective compressive strength of a column increases as it is confined by the slab, and the design codes mandate three different effective compressive strengths for interior columns (confinement on four sides), exterior columns (confinement on three sides), and corner columns (confinement on two sides). For both corner and exterior columns, the confinement effect of the slab is significantly smaller than that for the interior column, and there is a more marked decrease in load transfer performance. However, there is still a lack of theoretical studies investigating the effective compressive strengths of the corner and exterior columns. Therefore, based on the analysis model established in previous research, this study has proposed an equation for calculating the effective compressive strengths of the corner, exterior and isolated columns without any confinement effects of the slab. In addition, axial loading tests of isolated columns were conducted and the proposed equation was verified.

현재 서양의학에서 활용되고 있는 항암 요법으로는 外科處置, 化學療法, 放射線療法 및 免疫療法 等이 있으며, 그 중에서는 抗癌劑에 의한 화학요법과 방사선요법이 가장 많이 응용되고 있다. 그런데 이들은 癌細胞뿐만 아니라 正常細胞까지도 殺傷함으로써 腫瘍細胞를 억제하는 동시에 骨髓造血器, 消化系統 및 免疫機能을 포함하는 인체의 정상적인 기능을 손상시키는 문제점으로 그 사용에 제한을 받고 있다. 따라서, 본 연구는 蔘茸扶正湯의 항암요법으로 손상된 조직의 회복 및 조혈촉진 효과를 규명하기 위해 생쥐를 대상으로 하여 실험하였다. 그 결과, 생쥐 비장세포에 대한 增殖效果, 造血促進因子의 分泌能, 방사선에 대한 임파구의 防禦效果, 방사선에 대한 조혈세포 防禦效果, 방사선(9Gy)을 조사받은 생쥐의 生存率 등에서 유의성있는 결과를 얻어내어 아래와 같이 보고하는 바이다. Radiotherapy is an irreplaceable method of cancer treatment. But it has several side effects, especially damages to the hemopoietic and Immune system. Therefore radioprotectors are required to treat cancer successfully. A lot of Herbs and Herbal prescriptions are reported to have radioprotective effects. Above all, those to support the healthy energy and strengthen the body resistance are found more effective. This study was performed to evaluate the radioprotective effects of prescription Shenrong Fuzheng Tang(S. F. T), which consists of 16 kinds of herbs. We investigated proliferation of murine splenocytes, secretion of colony-stimulating-factors(CSFs), immunocompetence after irradiation in-vitro, and Endogenous spleen colony assay, survival assay in-vivo. When splenocytes were cultured with Shenrong Fuzheng Tang (S.F.T) (500㎍/㎖), proliferation was enhanced 5.7 times compared to control cultured with medium alone(P〈0.05) and, showed highest proliferation at 4th day after incubation. In order to evaluate stimulation of hemopoiesis of Shenrong Fuzheng Tang(S.F.T), the supernatant of splenocytes cultured with optimal concentration of Shenrong Fuzheng Tang(S.F.T) was used to measure CSFs secretion. The result showed enhanced secretion of colony-stimulating-factors(CSFs) compared to control(P〈0.05). To evaluate the protective effect of lymphocytes from irradiation, proliferation of splenocytes stimulated by LPS and ConA after incubation with Shenrong Fuzheng Tang(S.F.T) for 24h Prior to Irradiation(1∼3 Gy) was measured. The results showed higher proliferation of Shenrong Fuzheng Tang(S.F.T.) treated cells than that of non-treated cells. And percentage increases of irradiated splenocytes per non-irradiated splenocytes were also higher in Shenrong Fuzheng Tang(S. F. T)-treated cells than control. Endogenous spleen colony assay, to evaluate the protection of hemopoietic cells form irradiation, showed increased number of colonies(p=0.03) in Shenrong Fuzheng Tang(S.F.T) treated murine spleen(10.3±1.9) compared to non-treated murine spleen(3.4±0.8). Survival time of mice irradiated with lethal dose of γ-ray(9Gy) was prolonged in Shenrong Fuzheng Tang(S.F.T) treated group prior to irradiation as compared to non-treated group. According to these results we can suggest that prescription Shenrong Fuzheng Tang(S.F.T) has radioprotective effects and be used to protect the hemopoietic and immune system from damages of anti-cancer radiotherapy.

Background: Paraquat is a bipyridyl compound, and when ingested, concentrated paraquat can cause either rapid death from multisystem failure and cardiovascular shock or delayed death from progressive pulmonary fibrosis. Paraquat is poorly absorbed by inhalation, but when ingested orally, severe illness can occur. Death usually occurs within 2 days if more than 50 ㎎/㎏ of paraquat is ingested . The most important prognostic indicator is the quantity of paraquat absorbed, as shown by the plasma paraquat concentration, and the prognostic indication depends mostly on the description given by the patients and their families about the amount of paraquat ingested, which is often underestimated or overestimagted. For these reasons, we tried to compare the plasma paraquat concentrations with amount of paraquat described by patients or their families. Methods: We reviewed the medical records of 59 patients with acute paraquat poisoning from February 1998 through February 1999, the paraquat concentrations in plasma were measured at Presbyterian Medical Center by using high performance liquid chromatography. Results: There was a striking discrepancy between the plasma paraquat concentration and the ingested amount described by the patients or their families. Conclusion: We recommend that the plasma paraquat concentration be measured in patients being treated for acute paraquat poisoning.
