  • Safe shutdown earthquakes (SSE) of four existing nuclear power plant sites were evaluated by using a probabilistic method. It turned out that the SSE's of the two sites are smaller than those of the rest. Site-specific response spectra were developed for two sites of which SSE's show a comparatively large difference. The result shows that the site-specific response spectrum of one site is higher by a factor of 1.5 than that of the other. The comparison of uniform hazard spectrum and site-specific response spectrum at one of the two sites shows that the both spectra are consistent with each other.

  • Samsoeum (SSE) is used in traditional oriental medicine for various medicinal purposes. However, the exact mechanism that accounts for the anti-allergy and anti-inflammatory effects of the SSE is still not fully understood. The aim of the present study is to elucidate whether and how SSE modulates the allergic reactions in vivo, and inflammatory reaction in vitro. In this study, we showed that SSE significantly decreased compound 48/80-induced systemic anaphylaxis, ear-swelling response, histamine release from preparation of rat peritoneal mast cells and anti-dinitropheny IgE-induced passive cutaneous reaction. Also, SSE inhibited the expression of inflammatory cytokine and cyclooxygenase-2 in PMA plus A23187-stimulated human mast cells (HMC-1). In addition, we showed that anti-inflammatory mechanism of SSE is through suppression of nuclear factor-${\kappa}B$ activation and $I{\kappa}B-{\alpha}$ phosphorylation/degradation in HMC-1. These results provided new insight into the pharmacological actions of SSE as a potential molecule for therapy of inflammatory allergic diseases.

  • Background: Shoulder stabilization commonly involves two components: the glenohumeral stabilization exercise (GSE) and scapular stabilization exercise (SSE). Despite the fact that the shoulder stabilization has advantageous merit, to our knowledge, only a few studies have compared the superior of the GSE and the SSE. Objects: The purpose of this study was to assess the effects of GSE in patients with nonspecific shoulder pain. Methods: Thirty subjects with nonspecific shoulder pain were randomly divided into an experimental group and control group, each with 15 patients. The experimental group used an GSE, whereas the control group did SSE. All subjects were measured in shoulder stability, scapular symmetric alignment, pain, muscle power, and range of motion before and after the intervention. Results: GSE resulted in significantly better shoulder stability (p=.046, from $8.67{\pm}7.54$ score to $13.93{\pm}9.40$) in the experimental group compared with SSE in the control group. However, no significant effects were observed for scapular symmetric alignment including the angles of inferior scapular distance (p=.829) and inferior scapular height difference (p=.735), pain (p=.113), muscle power including shoulder flexion (p=.723) and abduction (p=.897) and range of motion including shoulder flexion (p=.853) and abduction (p=.472). Conclusion: These findings suggest that GSE may be more effective in increasing the shoulder stability than the SSE in patients with nonspecific shoulder pain, probably through a centralization effect on the shoulder mechanism.

  • Optical characteristics of excitonic blue and green emission of Te-doped ZnSSe:Te epitaxial layers, grown by molecular beam epitaxy, were investigated by photoluminescence (PL) measurements. The Te-doped ternary specimen shows strong blue or green emission (at 300K) which is assigned to $Te_1$ or $Te_n$ $(n{\geq}2)$ cluster cluster bound exciton, respectively. Bright green and blue light emitting diodes (LEDs) have been developed using ZnSSe:Te system as an active layer. The green LEDs exhibit a fairly long device lifetime (>2000 h) when operated at 3 $A/cm^2$ under CW condition at room temperature.

  • Purpose: We evaluated whether Spatholobus suberectus extract (SSE) can be used as a means of preventing and treating osteoporosis by measuring its effect on osteoclast differentiation, gene expression, and bone resorption. Methods: SSE was used to examine the effect on RAW 264.7 cells stimulated with RANKL to induce bone resorption. The inhibitory effect of TRAP formation and the expression of the bone resorption factors TRAP, cathepsin K, and MMP-9 during differentiation were measured. The effects on the differentiation-related factors NFATc and TRAIL and on the expression of OC-STAMP, DC-STAMP, ATP6v0d2, MITF, c-Fos, and inflammation-related factors were also evaluated. The effect on bone resorption was evaluated by culturing RANKL-treated osteoclasts on artificial bone fragments and observing the resulting resorption traces. The effect on bone damage in experimental animals was also measured. Results: SSE inhibited the differentiation of RANKL-stimulated osteoclasts into osteoclasts and suppressed the expression of cathepsin K, TRAP, MMP-9, NFATc1, TRAIL, MITF, OC-STAMP, DC-STAMP, ATP6v0d2, and c-Fos genes. Bone pore formation due to osteoclast action was also inhibited, and LPS-induced bone loss was suppressed in animal experiments. Conclusions: SSE could be useful for the prevention or treatment of osteoporosis by inhibiting osteoclast differentiation and bone resorption and suppressing bone loss induced in experimental animals. However, studies of larger populations are required.

  • Herein, we present effective polygonal finite elements to which the strain-smoothed element (SSE) method is applied. Recently, the SSE method has been developed for conventional triangular and quadrilateral finite elements; furthermore, it has been shown to improve the performance of finite elements. Polygonal elements enable various applications through flexible mesh handling; however, further development is still required to use them more effectively in engineering practice. In this study, piecewise linear shape functions are adopted, the SSE method is applied through the triangulation of polygonal elements, and a smoothed strain field is constructed within the element. The strain-smoothed polygonal elements pass basic tests and show improved convergence behaviors in various numerical problems.

  • This study conducted an empirical analysis of SSE-listed companies to verify the effects of evaluation and disclosure of internal control systems on the agency costs management and controlling shareholders. Agency costs can affect the valuation of accounting information as asymmetry of information in the relationship between a company and its stakeholders, or induce financial costs as an adverse selection. If the firm's agency costs are reasonable, the valuation of the company can also move in a relatively positive direction. In this study, the evaluation information of the internal control system was analyzed through sales management ratio and equity ratio as substitute variables to analyze the relationship between management and agent costs of the controlling shareholders. In addition, independent control ratio, capital balance ratio, and company scale were used as control variables, as a result of the analysis, the evaluation information of internal control was found to be related to the agency costs of managers and governance structure. This study can be conducted to positive factors in evaluating the reliability and corporate value of accounting information according to the evaluation of internal control of SSE-listed companies and helps to understand the financial reporting environment.

  • Smilax sieboldii is one of the Smilax species. A number of Smilax plants have multiple physiologically-active components and anti-inflammatory/anti-oxidant effects. Antiobesity effects induced by Smilax sieboldii have not been reported. In this study, we investigated the effects and molecular mechanisms of anti-obesity activity of 70% ethanol Smilax sieboldii extract (SSE). The anti-obesity effect of SSE was determined using 3T3-L1 adipocytes. We confirmed that SSE was not cytotoxic to murine 3T3-L1 preadipocytes, we evaluated SSE dose-dependently decreased the accumulation of lipids via an Oil Red O assay and triglyceride assay. These anti-obesity activities of SSE were mediated by the inhibition of adipogenesis-related marker genes (peroxisome proliferator activated receptor-γ, CCAAT-enhancer-binding protein α, and SREBP1c) and lipogenesis-related marker genes (fatty acid synthase and aP2). These results suggest that SSE has the potential to exert anti-obesity and anti-hyperlipidemia effects by regulating adipogenic transcription factors and inhibiting the expression of adipogenic markers.
