  • Reliability analysis is a probabilistic approach to determine a safety level of a system. Reliability is defined as a probability of a system (or a structure, in structural engineering) to functionally perform under given conditions. In the 1960s, Basler defined the reliability index as a measure to elucidate the safety level of the system, which until today is a commonly used parameter. However, the reliability index has been formulated based on the pivotal assumption which assumed that the considered limit state function is normally distributed. Nevertheless, it is not guaranteed that the limit state function of systems follow as normal distributions; therefore, there is a need to define a new reliability index for no-normal distributions. The main contribution of this paper is to define a sophisticated reliability index for limit state functions which their distributions are non-normal. To do so, the new definition of reliability index is introduced for non-normal limit state functions according to the probability functions which are calculated based on the convolution theory. Eventually, as the state of the art, this paper introduces a simplified method to calculate the reliability index for non-normal distributions. The simplified method is developed to generate non-normal limit state in terms of normal distributions using series of Gaussian functions.

  • Participates in actin remodeling through Rac and receptor endocytosis via Rab5. Here, we used yeast two-hybrid system with Eps8 as bait to screen a human brain cDNA library. ITSN2 was identified as the novel binding factor of Eps8. The interaction between ITSN2 and Eps8 was demonstrated by the in vivo co-immunoprecipitation and colocalization assays and the in vitro GST pull-down assays. Furthermore, we mapped the interaction domains to the region between amino acids 260-306 of Eps8 and the coiled-coil domain of ITSN2. In addition, protein stability assays and immunofluorescence analysis showed ITSN2 overexpression induced the degradation of Eps8 proteins, which was markedly alleviated with the lysosome inhibitor NH4Cl treatment. Taken together, our results suggested ITSN2 interacts with Eps8 and stimulates the degradation of Eps8 proteins.

  • Normal state EPR signals have been studied for the n-type$ high-T_c$ superconductors $Nd_{1.85}Ce_{0.15}CuO_{4-x} and Nd_2CuO_{3.6-x}F_{0.4-y}.$ Since EPR signals were observed only in quenched non-superconducting samples and were absent in furnace-cooled samples, our results suggest that no normal state EPR signals come from pure phase n-type hihg-Tc superconductors. Our observation is consistent with previously reported absence of nomal state EPR signals in the p-type high-Tc superconductors.

  • In this study, we measured the partial discharge phenomenon of inside the closed switchgear, using ultra wide band antenna. The characteristics of $\Phi-q-n$ in the normal state are stable, and confirmed at less than 0.01, but in proceeding states, about 2 times larger. And in the abnormal state, it grew hundreds of times larger compared with normal state. According to K-means analysis, if slant of discharge characteristics is a straight line close to "0" and standard deviation is small, it is in a normal state. However if we can find a peak from K-means clusters and standard deviation to be large, it is in an abnormal state.

  • Objective and Methods : This study was performed to evaluate the anticonvulsant, antioxidant effect of modified formulas Korean traditional medicine Cheongsinhwadam-Jeon(CSHDJ). The extract of CSHDJ was administered (p.o.) to mice for 14 days in anticonvulsant and antioxidant tests. Results : The pretreatment of CSHDJ extract prohibited pentylenetrazol (PTZ)-induced convulsion. In PTZ-induced convulsion, lowered level of brain ${\gamma}$-aminobutyric acid(GABA) was restored normal state by the pretreatment of CSHDJ. Increased level of brain glutamic acid was lowered to normal state by CSHDJ, and increased activity of brain ${\gamma}-aminobutyric$ acid transaminase(GABA-T) was reduced to normal state by CSHDJ. In PTZ-induced convulsion, increased level of brain lipid peroxide was lowered to normal state by the pretreatment of CSHDJ. Increased activity of brain xanthine oxidase(XOD) was lowered by CSHDJ, and increased activity of brain aldehyde oxidase lowered to normal state by CSHDJ. In PTZ-induced convulsion, increased activities of superoxide dismutase(SOD) and catalase in brain were lowered by the pretreatment of CSHDJ, whereas increased level of glutathione and increased activity of gluthathione peroxidase in brain were not changed significantly. Conclusions : Above results suggest that CSHDJ has anticonvulsant, antioxidant effect. That seems to be strongly related with the levels of GABA, glutamate, lipid peroxide and the activities of GABA-T, XOD, aldehyde oxidase, SOD, catalase in brain tissue. From these results, CSHDJ could be applied to various convulsive disorders.

  • Objectives: This study was aimed to investigate the emotional state and personality characteristics of alopecia aerata patient and to determine whether these characteristics are similar with those of neurotic patient. Methods : 20 alopecia aerata patients, 20 neurotic patients, and 20 normal healthy controls were studied. Beck Depression Inventory(BDI), State and Trait Anxiety Inventory(STAI) and Korean standardized edition of Catell's 16 Personality factors Questionnaire(16PF) were used for assessment. Results: 1) Total score of BDI was higher in neurosis group than alopecia aerata group and normal control group(p<0.05). Inspire of statistical non-significance, total score of in alopecia aerata group was higher than normal control group. 2) Total scores of state anxiety and trait anxiety in alopecia aerata and neurosis group were significantly higher than normal control group(p<0.001). 3) In first-stratum source traits of 16PF, normal control group was significantly higher than alopecia aerata group and neurosis group in B-factor(intelligence) and C-factor(ego-strength)(p<0.05). Alopecia aerata group and neurosis group were significantly higher than normal control group in O-factor(guilt-proneness) and $Q_4-factor(tension,\;anxiety)$(p<0.001). 4) In second-stratum source traits of 16PF, alopecia aerata group and neurosis group were significantly higher than normal control group in ANX-factor(anxiety)(p<0.05). Conclusions : These results suggest that emotional state and personality characterstics of patients with alopecia aerata are a distinguishable different to compare with normal control, and are very similar with those of neurotic patients. The authors propose that psychiatric management in patient with alopecia aerata will be more benificial.

  • This paper is to execute a study for characteristic analysis of synchronization clock and maximum network node number with various clock states, normal, SPT, LPT, in NG-SDH networks. Through the simulations, maximum network node numbers showed from 42 to 38 nodes in normal state. In SPT state, maximum network node numbers, when the last NE network applied to only SPT state, presented from 19 to 4 nodes, much less than normal state. Node numbers to meet specification in case of occurrence of SPT state in all NE networks decreased greatly. In LPT state, all maximum node numbers, when the last NE network applied to only LPT state, presented more than 50 nodes, and the results in case of occurrence of LPT state in all NE networks were also identified. However, node numbers to meet specification in case of LPT state in all DOTS networks were few large with difference between LPT and normal or SPT state.
