원자력발전소에서 사용되는 SOE 계통은 발전소 자료수집계통의 일부분이다. 기존 원자력발전소 SOE 계통은 컴퓨터의 하드웨어 및 소프트웨어를 자료수집계통과 공유하고 3개의 프로세서를 사용하여 사고나 트립신호를 처리하는 복잡한 구조를 갖고 있다. 더구나 발전소 컴퓨터계통에서 3개의 SOE 프로세서로 동기신호가 전송될 때 이 신호와 발전소 컴퓨터 계통으로 전송되는 데이터와 충돌가능성이 매우 높다. 이러한 문제는 SOE 계통의 고장을 발생시켜 사고나 트립의 추이분석을 불가능하게 한다. 본 논문에서는 기존 SOE 계통의 제약사항을 검토하고 단일 프로세서를 갖는 새로운 SOE 계통을 제안한다. 그리고 제안된 SOE 계통에 대한 시험계통을 설계, 구현 및 시험하였다.

The Sequence Of Event (SOE) system used in nuclear power plants is a part of the Plant Data Acquisition System (PDAS). The SOE system of the existing nuclear power plant share the computer H/W and S/W, and required more complicated structure to provide the events or trip signals. Moreover, there are high potential of collision between synchronization signals and data transmitted to the Plant Computer System(PCS) when the synchronization signals are sent from PCS to the three SOE processors. When this collision happens the SOE system will break down, thus it is not possible to analyze the trend of events or trips. This paper issued the limitation items of the existing SOE system and proposed the revised SOE system.

The stochastic origin ensembles method with resolution recovery (SOE-RR) has been proposed to reconstruct proton-induced prompt gammas (PGs), and the reconstructed PG image was used for range verification. However, due to low detection efficiency, the number of valid events is low. Such a low-count condition can degrade the accuracy of the SOE-RR method for proton range verification. In this study, we proposed two strategies to improve the reconstruction of the SOE-RR algorithm for low-count PG imaging. We also studied the number of iterations and repetitions required to achieve reliable range verification. We simulated a proton beam (10⁸ protons) irradiated on a water phantom and used a two-layer Compton camera to detect 4.44-MeV PGs. Our simulated results show that combining the SOE-RR algorithm with restricted volume (SOE-RR-RV) can reduce the error of the estimation of the Bragg peak position from 5.0 mm to 2.5 mm. We also found that the SOE-RR-RV algorithm initialized using a back-projection image could improve the convergence rate while maintaining accurate range verification. Finally, we observed that the improved SOE-RR algorithm set for 60,000 iterations and 25 repetitions could provide reliable PG images. Based on the proposed reconstruction strategies, the SOE-RR algorithm has the potential to achieve a positioning error of 2.5 mm for low-count PG imaging.

PS2 기반 게임 SOE(State Of Emergency)가 성공을 거두자 이 게임의 개발업체인 미국 VIS엔터테이먼트사는 이를 X-box에서도 게임이 가능하도록 변환시키기로 결정했다. 이는 SOE의 성공을 보다 오랫동안 누리기 위한 방안이었다. 시간은 충분했다. PS2와의 계약기간이 8개월이나 남아 있었기에 그 이전에 SOE의 X-box버전을 개발해야할 필요성은 없었다. 문제는 수작업으로 조정된 모든 코드를 수정해야 한다는 점이었다. SOE의 사례를 바탕으로 새로운 미션에 대한 해결법을 찾아보자.

The paper aims to combine balance sheet analysis at the firm level with the International Monetary Fund's public debt sustainability assessment framework to assess state-owned enterprises' (SOE) leverage as a contingent liability to the public sector. Based on company data and the interest coverage ratio as a measure of debt at risk, aggregate baseline scenarios are projected to gauge the magnitude of SOE debt as a contingency. SOE's financial and debt ratios are first bootstrapped to generate firm-level distributions and then averaged into a fan chart of the economy-wide SOE contingent liability. Applied to the People's Republic of China as an example, the study finds that by the end of 2015 SOE leverage had grown to a substantial liability. However arbitrary the assumptions underlying these projections, it would appear that even if authorities had to mop up as much as 20% of SOE debt at risk gone bad, this would have been manageable at roughly 2.7% of the gross domestic product in 2016 or 5.5% by 2021. This projection framework is fully amenable to alternative assumptions and settings, which makes it a useful analytical tool to monitor contingent liabilities from non-financial corporate debt that have been building in emerging and advanced economies alike.

To develop a value-added low-salt fermented seafood with a long shelf-life, we prepared seasoned low-salt fermented Omandungi Styela plicata supplemented with fermentation alcohol (SOE). The SOE was produced by washing and dewatering shelled Omandungi, followed by cutting and salting for 24 h at 0±1℃. The salted Omandungi was seasoned and fermented with garlic, ginger, monosodium glutamate, red pepper, sesame, sorbitol, and sugar, for 7-8 days at 0±1℃. After adding 3-5% fermentation alcohol, the seasoned fermented Omandungi was packed in a polyester container. The salinity, volatile basic nitrogen content, and viable cell count of SOE were 4.8%, 22.1-22.2 mg/100 g, and (1.2-1.9)×10³ CFU/g, respectively. Compared with the control, addition of 3-5% fermentation alcohol inhibited the decrease in freshness, texture degradation, and growth of residual bacteria. Additionally, the SOE showed good storage stability and organoleptic qualities when stored at 4±1℃ for 40 days. The total amino acid content of SOE was 2,186.0 mg/100 g, mainly comprising glutamic acid, aspartic acid, lysine, and phenylalanine. The free amino acid content was 189.0 mg/100 g, and mainly included taurine, glutamic acid, methionine, alanine, and proline.

Background: Sanguisorba officinalis has been used in traditional Asian medicine owing to its beneficial effects on various diseases. The purpose of this study was to evaluate the effect of S. officinalis on the antioxidant system of Streptozotocin (STZ) and Alloxan (ALL) induced diabetic rats. Methods and Results: Triglyceride and Low-Density Lipoprotein (LDL)-cholesterol levels decreased in the STZ-induced diabetic groups treated with S. officinalis extract (SOE) compared to the corresponding levels in the control groups. Moreover, in the ALL-induced diabetic groups, SOE reduced triglyceride, LDL-cholesterol, and High-Density Lipoprotein (HDL)-cholesterol levels. Malondialdehyde (MDA) levels decreased significantly in the STZ and ALL-induced groups treated with SOE compared to the corresponding levels in the control group. Further, Glutathione (GSH) levels increased but did not reach statistical significance. The levels of Superoxide Dismutase (SOD) and Glutathione-S-Transferase (GST) showed a tendency to recover with SOE treatment in the STZ and ALL-induced diabetic groups. In addition, Catalase (CAT) levels in the SOE treatment group decreased significantly compared to those in the control group. Conclusions: These results suggest that SOE might be an effective agent in attenuating oxidative stress in diabetic patients by improving blood lipid profiles and inducing the anti-oxidative enzyme systems.

Safety operational envelope (SOE) is the area which guarantees the safety of a submarine from the accident such as jamming and flooding. The maximum safe depth is set to prevent the damage to the hull from increasing water pressure with depth. A minimum safety depth is set to prevent a submarine from the exposure above the free surface and collision against surface ship. The prediction method for the SOE in the design phase is needed to operate the submarine safely. In this paper, the modeling and calculation methods of the SOE are introduced. Main ballast tank blowing modeling and propeller force modeling are conducted to simulate the accidents and the recovery process. The SOEs are established based on the crash stop and emergency rising maneuver simulation. From the simulation results, it can be known that the emergency rising maneuver is more effective recovery action than the crash stop.

This thesis attempts to investigate the design of the bracket sets(eave-supporters) of Dapo-style architecture(multiple-bracket architecture) in order to discover the change and the characteristic of the Yon-Hwa-Hyong bracket sets. The external shape of eave-supporters has been evolved as following order: Kyo-Du-Hyong, Soe-Seo-Hyong, Cho-Gak-Soe-Seo-Hyong, and Yon-Hwa-Soe-Seo-Hyong. The internal shape has been developed as following order: Kyo-Du-Hyong. Cho-Gak-Hyong and Yon-Hwa-Hyong. Kyo-Du-Hyong represents the 17th century style and Yon-Hwa-Hyong has been used since the mid 18th century. Cho-Gak-Hyong signifies the transformation in the structural and designing role of column section and middle section and there appears a unified aspect in Yon-Hwa-Hyong. The transformation from Kyo-Du-Hyong towards Yon-Hwa-Hyong suggests that this is an intention of symbolizing the Buddhist teachings inside and outside of the eave-supporters. The purpose of this change establishes the Buddhist land.

Somatic cell nuclear transfer (SCNT) has generally demonstrated that a differentiated cell can convert into a undifferentiated or pluripotent state. In the SCNT experiment, nuclear reprogramming is induced by exposure of introduced donor nuclei to the recipient cytoplasm of matured oocytes. However, because the efficiency of SCNT still remains low, a combination of SCNT technique with the ex-ovo method may improve the normal development of SCNT embryos. Here we hypothesized that treatment of somatic cells with extracts prepared from the germinal vesicle (GV) stage Siberian sturgeon oocytes prior to their use as nuclear donor for SCNT would improve in vitro development. A reversible permeability protocol with $4{\mu}g/mL$ of digitonin for 2 min at $4^{\circ}C$ in order to deliver Siberian sturgeon oocyte extract (SOE) to porcine fetal fibroblasts (PFFs) was carried out. As results, the intensity of H3K9ac staining in PFFs following treatment of SOE for 7 h at $18^{\circ}C$ was significantly increased but the intensity of H3K9me3 staining in PFFs was significantly decreased as compared with the control (p<0.05). Additionally, the level of histone acetylation in SCNT embryos at the zygote stage was significantly increased when reconstructed using SOE-treated cells (p<0.05), similar to that of IVF embryos at the zygote stage. The number of apoptotic cells was significantly decreased and pluripotency markers (Nanog, Oct4 and Sox2) were highly expressed in the blastocyst stage of SCNT embryos reconstructed using SOE-treated cells as nuclear donor (p<0.05). And there was observed a better development to the blastocyst stage in the SOE-treated group (p<0.05). Our results suggested that pre-treatment of cells with SOE could improve epigenetic reprogramming and the quality of porcine SCNT embryos.
