Human gets almist all of his knoweledge from the recognition and the accumulation of input patterns,image or sound,the he gets theough his eyes and through his ears.Among these means,his chracter recognition,an ability that allows him to recognize characters and understand their meanings through visual information, is now applied to a pattern recognition system using neural network in computer. Recurrent neural network is one of those models that reuse the output value in neural network learning.Recently many studies try to apply this recurrent neural network to the classification of static patterns like off-line handwritten characters. But most of their efforts are not so drrdtive until now.This stusy suggests a new type of recurrent neural network for an deedctive classification of the static patterns such as off-line handwritten chracters.Using the new J-E(Jordan-Elman)neural network model that enlarges and combines Jordan Model and Elman Model,this new type is better than those of before in recobnizing the static patterms such as figures and handwritten-characters.

본 연구의 목적은 장애인행정도우미가 지각하는 직무만족에 대한 자기효능감의 영향을 장애수용정도가 매개하는지를 실증적으로 검증하는 것이다. 이를 위하여 수도권 주민센터 253개소의 장애인행정도우미 253명을 대상으로 조사하였으며, 수집된 자료에 대하여 구조방정식을 이용하여 자기효능감, 장애수용, 그리고 직무만족 간의 관계를 확인하였다. 분석 결과, 장애인행정도우미가 지각하는 자기효능감은 장애수용에 정적으로 유의한 영향을 미치며, 장애수용은 직무만족에 정적으로 유의한 영향을 미치는 반면, 자기효능감은 직무만족에 유의한 영향을 미치지 않는 것으로 확인되어 장애수용이 자기효능감과 직무만족 간의 관계를 완전매개하는 것으로 검증되었으며, 이러한 매개효과는 통계적으로도 유의한 것으로 확인되었다. 이상의 결과에 근거하여 장애인행정도우미의 직무만족도를 향상시킬 수 있는 실천적 함의를 제시하였다.

본 논문에서는 시간의 축에 따라 점진적으로 확산되는 정보 네트워크를 효과적으로 표현할 수 있는 시각화 도구를 소개하고자 한다. 이것은 기존의 정적인 데이터에 대한 정적인 시각화 결과물을 제시하는 시각화 도구들과는 달리, 시간의 축에 따라 동적으로 성장하는 데이터를 효과적으로 표현할 수 있다는데 그 차이가 있다. 이를 위해 그래프 기반의 정보 확산 네트워크 모델을 정의 하고, 이 그래프에 시간의 축에 따른 데이터의 성장을 반영하여, 정보 확산 과정을 시각화 할 수 있는 도구를 제작하였다. 결론적으로, 본 논문에서 제시하는 도구는 시간의 축에 따라 점진적으로 성장하는 정보 네트워크의 성장 과정을 시각화함으로 해서, 복잡하게 엉켜 있는 정보들이 어떻게 확산되며, 어떤 모양으로 생겼는지, 또 어떻게 진화하는가에 대한 시각적 재현을 통해 정보 확산 네트워크의 속성을 이해하는데 도움을 줄 수 있는 새로운 시각화 도구를 제시했다는데 그 의미가 있다.

In this study, nonlinear static aeroelastic analysis system for a high-aspect-ratio wing are developed using the transonic small disturbance (TSD) and large deflection beam theory and validated. For the coupling between fluid and structure, the transformation of displacement from the structural mesh to aerodynamic one is performed by the shape function of the beam finite element and the inverse transformation of force by work equivalent load concept. Also, for the static aeroelastic analysis of the wing the use of TSD aerodynamics are justified. The validation of the system includes one of the efficient transformation methods of force and displacement.

The objective of this paper is to investigate the lining board's capacity for the static load. The test is to inspect the possibility of retrofit and efficiency, which is required to upgrade the structure's capacity and to examine the effects of the improvements of specimen by using structural analysis, and static loading test, respectively. As the result of static loading test for measured stresses and deflections. H type lining board take sufficient load carrying capacity and high stiffness which likes ultimate load, displacement, and bending stresses of intermediate span and top, bottom flange more than 3 times channel type lining board.

An analytical solution method is described to estimate the developed static and dynamic horizontal earth pressures behind a vertical or inclined rigid wall experiencing outward toranslational movement. The results predicted by the developed method of analysis are compared with chose from the experimental model testg on sandy. The comparisons show good agreements at various stases of wall movement. When the wall i9 inclined with a certain angle in the direction of the supported strand sass, the effects of reduction in developed static and dynamic horizontal earth pressures are also analyzed. Finally, results of analytical parametric study are presented to demonstrate the effects of various parameters, such as wall friction angle and internal strand friction angle.

In this paper a new equivalent static analysis method of dynamic behavior during progressive collapse is presented. The proposed analysis method uses the equivalent nodal load for the element stiffness which represents the dynamic behavior influence caused by the deletion of elements during progressive collapse analysis. The proposed analysis method improves the efficiency of progressive collapse analysis haying the iterative characteristic because the inverse of the structural stiffness matrix is roused in the reanalysis. By comparing the results obtained by this analysis method with those of GSA code analysis and time history analysis, it is shown that the results obtained by this analysis method more closely approach to those of time history analysis than by GSA code analysis.

The GF(Gust Factor) method is usually used as a method to evaluate equivalent static wind loads for general structures. The GF method is performed on the assumption that the shape of the equivalent static wind load profile is typically similar to that of mean wind loads. The shape of fluctuating wind loads could be quite different with that of the mean wind loads in case of large-span structures. So, the effect of higher modes as well as first mode must be considered to evaluate the wind loads. In this study, the ACS (Advanced Conditional Sampling) method is suggested to evaluate of equivalent static wind loads after investigating about GF and LRC method. The An method ran derive effective static wind loads by combining wind pressures and inertia forces of a structure chosen at a maximum load effect. The maximum load effect is assessed with the time history analysis using pressure data measured in wind tunnel tests. Equivalent static wind loads evaluated using ACS, GF, and LRC methods are compared to verify the effectiveness of ACS method.

The purpose of this study is to identify Actor and Partner Effects of Marital Intimacy according to Personality Characteristics of Couples Participating in Dance Sports. The study participants collected data on 148 couples participating in dance sports. After analyzing the APIM model using SPSS 25.0 and AMOS 25.0 to solve the research problem, The following conclusions were obtained the following conclusions were obtained: First, there were significant differences between husband and wife in relation to neurosis among personality traits, and the wife's neurosis about the husband's marital intimacy was affected by amulets and the wife was found to have relatively low static effects. Second, there were significant differences only to the husband in relation to openness among personality characteristics, and the wife's openness to the husband's marital intimacy was found to be relatively malleable, and the wife was found to be subject to the same level of static influence. Third, there were significant differences in personality traits in relation to extroversion only to the wife, and it was found that the wife was subject to relatively low static influence. Fourth, there were no significant differences between husband and wife in relation to sincerity among personality characteristics and they appeared to have a static effect on each other. Fifth, significant differences were found only to the wife in relation to affinity among personality characteristics, and the wife was found to be subject to relatively low static influence.
