The knowledge and information processing competence is one of the essential competencies in an information-oriented society which is highly related to science education. The purpose of this study is to investigate middle school students' difficulties in science inquiry activity in view of the knowledge and information processing competence. Collection, processing, and application of information are extracted as common elements of the knowledge and information processing competence through literature search. Data were obtained from eight students of a middle school in Seoul for five months and were analyzed based on constant comparative method to extract students' difficulties. As a result, the element of information collection is observed through science inquiry and the element of information processing is observed in hypothesis setting step, inquiry result analysis step, and inquiry result sharing step. The element of information application is observed in the creation of posters for sharing and inquiry reports. Difficulties in information collection were found in lack of confidence in information gathering, systematic search strategy, and information reliability. Difficulties in information processing appeared in the inexperience of analysis program use, information transformation, and interpretation of linkage information. Difficulties in information application were caused by the lack of effective organization and effective expression of information. In this study, it is meaningful to provide a clue as to how the knowledge and information processing competence can be established in science education.

Cross-lingual query expansion is usually based on the relationship among monolingual words. Bilingual comparable corpus contains relationships among bilingual words. Therefore, this paper proposes a method based on these relationships to conduct query expansion. First, the word vectors which characterize the bilingual words are trained using Chinese and Thai bilingual comparable corpus. Then, the correlation between Chinese query words and Thai words are computed based on these word vectors, followed with selecting the Thai candidate expansion terms via the correlative value. Then, multi-group Thai query expansion sentences are built by the Thai candidate expansion words based on Chinese query sentence. Finally, we can get the optimal sentence using the Chinese and Thai query expansion method, and perform the Thai query expansion. Experiment results show that the cross-lingual query expansion method we proposed can effectively improve the accuracy of Chinese and Thai cross-language information retrieval.

The article analyzes the impact of factors affecting the use of cost information is examined, which adds to the empirical evidence on the factors affecting the use of cost information in Vietnam's seafood processing firms. 58 seafood processing firms in Vietnam were surveyed using a questionnaire survey of all levels of management, chief accountants, and accountants. A total of 235 questionnaires were gathered for the survey. Because many of the surveys were invalid due to empty cells, the author selected to use 214 questionnaires. The 5-level Likert scale is familiarly used in many studies, so the author also quantifies each factor according to five levels. Quantitative research was carried out with SPSS 25 software. Research results show that 4 factors The function of cost information, cost management, information technology, and management support in the seafood processing industry in Vietnam all have a positive impact on the use of cost information. The author has provided recommendations based on the research findings to expand the use of cost information, consequently helping to improve the performance of Vietnamese seafood processing businesses. Managers must improve a variety of resources, including facilities (software, hardware), people (in-depth training on CAS for administration), departmental awareness, and UCI's ability to assess responsibility and reward in the organization.

Mediator 는 네트웍상에 분산되어 존재하는 이질적인 정보 원천(Information Source)들에 대한 통합 검색 서비스를 제공하는 시스템을 말한다. 본 논문은 이러한 mediator 시스템에서 이전 사용자들이 제기하였던 질의와 그 결과를 캐쉬에 저장하여 그것을 다음 사용자들이 제기하는 질의를 처리하는데 활용하기 위한 방법을 제안한다. Mediator 에서 유지/관리되는 결과 캐쉬의 구성 및 표현 방안을 제안한다. 본 논문에서는 실험을 통하여 이러한 결과 캐쉬를 사용할 경우 mediator에서의 질의 검색 성능이 향상될 수 있음을 보여준다.

우리의 주변에는 복잡한 소프트웨어 시스템(System)들로 둘러 쌓여 있으며 이러한 시스템의 혜택을 받는 일이 커짐에 따라 소프트웨어 신뢰성의 역할은 점차 커지게 되었다. 고장 시스템이 복잡해지면 고장의 원인이 하나의 수명분포에 의해서만 일어나지 않고 여러 원인이 혼합되어 발생 할 수 있다. 이러한 복잡한 시스템에 의한 우도함수가 적분하기 난해하므로 반복표본을 이용하는 깁스 알고리즘이 제안되었다.

Rendering complex 3D model on smart mobile device with limited processing power and memory is challenging. Without optimization, the complex 3D model cannot be rendered smoothly. Special techniques are required to take into account to speed up the processing. In this paper, we will discuss about some approaches to alleviate the problem.

The purpose of this study was to investigate the effect of consumer knowledge and involvement of apparel products on information processing style. The subjects of this study were female adults who lived in Seoul, Kyunggi or Incheon areas and Quota sampling using age and residential areas was employed. The data were obtained from 603 questionnaires. Data were statistically analyzed using SPSS 10 and LISREL 7.0. Major statistical methods were factor analysis, Cronbach's a coefficient, multiple regression analysis, and structural equation model analysis. The results were as follows: 1. Consumer knowledge significantly influenced information processing styles. Rational processing style was significantly influenced by objective knowledge, while experiential processing style was significantly influenced by subjective knowledge. 2. Involvement was related to the subjective knowledge more than objective knowledge. Consumers who had higher interest, social importance and followed latest fashion trends tended to process information more experientially.

정보추출 시스템의 목적은 관심의 대상이 되는 특정 정보를 선택적으로 찾아내 제시하는데 있다. 따라서 도메인 정보에 의존적인 방법으로 정보추출이 이루어질 수밖에 없고, 이에 따른 도메인 정보 구축의 부담이 컸다. 이러한 부담을 줄이기 위해 본 연구에서는 특정 주제영역과 관련한 문서로부터 자동으로 이벤트 문장을 추출하는 시스템을 제안한다. 이벤트 문장이란, 특정도메인에서 다루어지는 이벤트의 구체적인 내용을 포함하고 있는 문장이다. 이러한 문장을 추출함으로써 기본적인 수준의 정보추출 요구를 만족시킬 수 있을 뿐만 아니라, 주출된 이벤트 문장을 도메인 정보 구축에 활용할 수 있을 것이다. 본 연구에서는 동사, 명사, 명사구, 및 3W 자질을 이용하여 문장추출의 성능을 최대화하기 위한 방안을 제안하고, 세 개의 평가 도메인을 대상으로 실험을 수행하였다. 실험 결과, when 및 where 자질과 동사, 명사. 명사구의 가중치를 이용하여 문장 가중치를 계산함으로써 최적의 이벤트 문장추출 성능을 얻을 수 있음을 알 수 있었다.

The purpose of this paper is two-fold: 1) A novel algorithm in order to extract lane-related information from road images is presented; 2) Design specifications of an image processing onboard unit capable of extracting lane­related information in real-time is also presented. Obtaining precise information from road images requires many features due to the effects of noise that eventually leads to long processing time. By exploiting a FPGA and DSP, we solve the problem of real-time processing. Due to the fact that image processing of road images relies largely on edge features, the FPGA is adopted in the hardware design. The schematic configuration of the FPGA is optimized in order to perform 3 $\times$ 3 Sobel edge extraction. The DSP carries out high-level image processing of recognition, decision, estimation, etc. The proposed algorithm uses edge features to define an Edge Distribution Function (EDF), which is a histogram of edge magnitude with respect to the edge orientation angle. The EDF enables the edge-related information and lane-related to be connected. The performance of the proposed system is verified through the extraction of lane-related information. The experimental results show the robustness of the proposed algorithm and a processing speed of more than 25 frames per second, which is considered quite successful.
