  • 코로나19 펜데믹이 장기화되면서 비대면 업무가 늘어나고 단순반복적인 질문 및 업무에 대한 자동화 수요가 증가하였으며 성과도 보고 있다. 따라서 기업은 더 나아가 E2E 업무에 복잡한 여러 업무 프로세스를 연계하고 위해 AI 등 다양한 기술을 적용하여 모든 작업을 자동화하려고 시도하고 자동화 업무영역을 확장하고 있다. 하지만 Intelligent Process Automation(IPA)부분으로의 확장은 아직 적용사례 및 관련 솔루션을 찾아보기 어려울 정도로 시작 단계에 머물고 있어 복잡하고 다양한 업무 프로세스들로 구성되어 있는 전사업무의 자동화를 고려하고 있는 기업에서는 도입에 대한 의사결정을 내리기에는 부족한 면이 있다. 본 연구에서는 이를 해결하기 위하여 RPA, Chatbot, AI 기술을 적용한 Hyperautomation Platform(HAP) 구성을 제안하였고, HAP를 사용하여 지능형 프로세스 자동화를 가져올 수 있는 적용방안과 현업 업무에 적용 가능한 구현사례를 제시하여 객관적이고 종합적으로 도입을 검토할 수 있도록 하였으며, Hyperautomation 개념의 실현 가능성을 확인하여 HAP를 적극적으로 활용할 수 있도록 하는데 의미와 가치가 있다.

  • In recent years, most of the researches on pattern recognition are for medical diagnosis or for characters recognition. In fact its applications are very wide. In this paper, the pattern recognition is employed by linguistic translation, i.e. the output of Pattern Recognition is translated into another language. In this paper, it focuses on several fields: (1) System overview-explicate the functions of each part individually; (2) Criteria on the system-discuss the difficulties in each part; (3) System implementation-discuss how to design the approaches for constructing the system. Furthermore, intelligent approaches are considered be use on the system in different parts. They are discussed in the late paper, and also we concentrate on user interface, which can make a serious of processes in order, and easy control-just only pressing a few buttons. It is a new and creative attempt in digital system.

  • In this study, obtained large block sample and piston sample of marine clay in korea were performed unconfined compression and consolidation test. Soil properties of two type samples such as failure strain, between two parameter's ratio($E_{50}$ and $q_u$), and volumetric strain were used to evaluate sample disturbance. The result, large block samples show a low disturbance than piston samples. Therefore, we suggest new sample disturbance evaluated method through the relation of OCR and volumaric strain at shallow of marine clay in Korea and suggest new sample disturbance classified method by subdivided grade for failure strain of unconfined compression test.

  • A system for the recognition of machine printed Arabic script is proposed. The Arabic script is shared by three languages i.e., Arabic, Urdu and Farsi. The three languages have a descent amount of vocabulary in common, thus compounding the problems for identification. Therefore, in an ideal scenario not only the script has to be differentiated from other scripts but also the language of the script has to be recognized. The recognition process involves the segregation of Arabic scripted documents from Latin, Han and other scripted documents using horizontal and vertical projection profiles, and the identification of the language. Identification mainly involves extracting connected components, which are subjected to Principle Component Analysis (PCA) transformation for extracting uncorrelated features. Later the traditional K-Nearest Neighbours (KNN) algorithm is used for recognition. Experiments were carried out by varying the number of principal components and connected components to be extracted per document to find a combination of both that would give the optimal accuracy. An accuracy of 100% is achieved for connected components >=18 and Principal components equals to 15. This proposed system would play a vital role in automatic archiving of multilingual documents and the selection of the appropriate Arabic script in multi lingual Optical Character Recognition (OCR) systems.

  • The preconsolidation pressure has been commonly determined by oedometer test. However, it can also be determined by in-situ test, such as piezocone test with theoretical and(or) empirical correlations. Recently, Neural Network(NN) theory was applied and some models were proposed to estimate the preconsolidation pressure or OCR. However, since the optimization process of synaptic weights of NN model is dependent on the initial synaptic weights, NN models which are trained with different initial weights can't avoid the variability on prediction result for new database even though they have same structure and use same transfer function. In this study, Committee Neural Network(CNN) model is proposed to improve the initial weight dependency of multi-layered neural network model on the prediction of preconsolidation pressure of soft clay from piezocone test result. It was found that even though the NN model has the optimized structure for given training data set, it still has the initial weight dependency, while the proposed CNN model can improve the initial weight dependency of the NN model and provide a consistent and precise inference result than existing NN models.

  • This paper presents the logic based High Impedance Fault(HIF) detection rules for distribution lines. Due to the characteristics of HIF, which shows low current on relaying points, it is difficult to detect the fault occurred in distribution line by the conventional overcurrent relay(OCR) and/or harmonics relay. The HIF data were generated by using TACS in EMTP. In this paper, The harmonic index is defined as the ratio of harmonic component to fundamental component. The proposed HIF detection rules are obtained by analysing the difference between normal condition and HIF condition.

  • It is important to estimate the mechanical properties of clay since it is directly related to the design and the construction of geotechnical structures. Site exploration, which is composed of boring, sampling, in-situ, or laboratory tests, is preformed to estimate the mechanical properties. However, mechanical properties of clay measured from laboratory test may be different from in-situ properties due to disturbances occurred during sampling, transportation, storage, and trimming. In this study, the degree of disturbance according to sampling method was estimated with the test results of CK/sub o/U triaxial compression test on Yangsan clay. The soil samples were obtained by three types of sampling method, j.e., 76mm-tube sampler, 76mm-piston sampler, and block sampler. In order to evaluate the quality of samples, volumetric strain, undrained shear strength, secant Young's modulus, and pore pressure coefficient at peak measured from each sample were compared with one another. From the test results, it was observed that mechanical properties of the block and piston samples were more reliable than those of tube samples. But it was observed that the water content of piston was similar to that of tube samples at given depths while the water content of block samples was 14.3∼15.8% smaller than that of piston and tube samples. In addition to the evaluation of the quality of samples, relationship between c/sub u// σ/sub vc/'and OCR was established from the results of the CK/sub o/U triaxial compression tests, which were carried out using SHANSEP method. And also undrained shear strength was analyzed using the in-situ test data such as Cone Penetration Test(CPT), Dilatometer Test(DMT), and Field Vane Test(FVT) and was compared with that evaluated from CK/sub o/U triaxial compression test.

  • 과압밀비(過壓密比)와 전단속도(剪斷速度) 및 다짐율(率)이 점성토(粘性土)의 응력변형특성(應力變形特性)에 미치는 영향(影響)을 검토(檢討)하기 위해서 반부극하(反復戟荷)에 의(依)한 삼축압축시험(三軸壓縮試驗)을 한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 반부재하(反復載荷)를 했을 때 같은 변형(變形)에서 축차응력의 차(差)는 큰 변형(變形)에서 반부재하(反復載荷)했을 때 더욱 크게 나타났고 공극수압(空隙水壓)은 제하시(除荷時)에는 감소(減少)하다가 다시 증가(增加)하며 재재하(再載荷)되면서 급격히 증가하는 현상(現象)을 나타냈다. 2. 과압밀비(過壓密比)가 클수록 변형(變形)의 증가(增加)에 따라 회복되는 탄성변형률은 감소(減少)하였으며 제일재하계수(除一載荷係數)는 과압밀비가 증가(增加)할수록 감소(減少)하였다. 3. 전단속도(剪斷速度)가 증가(增加)함에 따라 탄성변형율(彈性變形率)은 증가(增加)하였고 변형(變形)의 증가(增加)에 따라 탄성변형율(彈性變形率)은 감소(減少)하였다. 제일재하계수(除一載荷係數)는 변형(變形)이 증가(增加)함에 따라 감소(減少)하였고 전단속도(剪斷速度)가 빠른 경우에 큰 값을 나타냈다. 4. 회복되는 탄성변형율(彈性變形率)은 다짐율이 증가(增加)함에 따라 크게 나타났고 또 변형(變形)이 증가(增加)함에 따라 탄성변형율(彈性變形率)은 약간 감소(減少)하는 경향(傾向)을 나타냈다. 제일재하계수(除一載荷係數)는 다짐율(率)의 증가(增加)에 따라 뚜렷한 경향(傾向)은 보이지 않았으나 일반적(一般的)으로 변형(變形)이 증가(增加)함에 따라 감소(減少)하는 경향(傾向)을 나타냈다.
