This paper proposes the OOPP(Optimized Online Portfolio Platform) design for the job seekers to search for the job competency necessary for employment and to write and manage portfolio online efficiently. The OOPP consists of three modules. First, JDCM(Job Data Collection Module) stores the help-wanted advertisements of job information sites in a spreadsheet. Second, CSM(Competency Statistical Model) classifies core competencies for each job by text-mining the collected help-wanted ads. Third, OBBM(Optimize Browser Behavior Module) makes users to look up data rapidly by improving the processing speed of a browser. In addition, The OBBM consists of the PSES(Parallel Search Engine Sub-Module) optimizing the computation of a Search Engine and the OILS(Optimized Image Loading Sub-Module) optimizing the loading of image text, etc. The performance analysis of the CSM shows that there is little difference in accuracy between the CSM and the actual advertisement because its data accuracy is 99.4~100%. If Browser optimization is done by using the OBBM, working time is reduced by about 68.37%. Therefore, the OOPP makes users look up the analyzed result in the web page rapidly by analyzing the help-wanted ads. of job information sites accurately.

급변하는 기업 환경 속에서 기업들은 선택과 집중 전략의 일부로 기업의 역량을 전문영역에 집중하고, 물류관리 등의 업무들은 3자 물류업체에 아웃소싱하고 있다. 이로 인하여 물류관련 산업이 전 세계적으로 급성장하고 있으며, 국내 3자 물류업체들 역시 경쟁우위를 확보하기 위하여 규모의 경제를 통한 비용 절감, 물류 기업들 간의 파트너십을 통한 고객서비스 향상, 신속하고 정확한 업무처리를 지원할 수 있는 정보화에 노력하고 있다. 그러나 대다수 국내 3자 물류업체들은 규모가 영세하고, 정보화 투자 및 운영을 하기에는 자금과 인력이 부족하여 적극적인 정보화 추진이 어려운 실정이다. 이에 따라 3자 물류업체들의 정보화 수준 향상을 위해서는 정확한 정보화 수준 파악과 그에 기초한 정보화 정책 수립이 선행되어야 한다. 그러나 국내 3자 물류업체의 정보화 수준 평가에 있어 정부기관 및 다른 산업을 대상으로 한 기존의 정보화 수준 평가 모형을 그대로 반영하기에는 적합하지 않다. 따라서 본 연구에서는 국내 3자 물류업체의 정보화 수준을 파악하기 위하여, 3자 물류업체들의 특성을 반영한 평가 모형을 개발하고, 이를 국내 3자 물류업체들을 대상으로 설문 조사하여 평가 모형의 타당성을 검증하고자 한다. 본 연구모형은 물류산업에서 가장 활발한 활동을 하고 있는 3자 물류업체들의 정보화 수준 파악을 위해 잣대가 될 수 있으며 향후 정보화 정책 수립, 정보화 효과 분석 등의 사후 평가 자료를 얻는 데 활용 될 수 있다.

In this paper, we propose a method to enhance adaptability in a dialogue system using the reinforcement learning that reduces response errors by trials and error-search similar to a human dialogue process. The adaptive dialogue strategy means that the dialogue system improves users' satisfaction and dialogue efficiency by loaming users' dialogue styles. To apply the reinforcement learning to the dialogue system, we use a main-dialogue span and sub-dialogue spans as the mathematic application units, and evaluate system usability by using features; success or failure, completion time, and error rate in sub-dialogue and the satisfaction in main-dialogue. In addition, we classify users' groups into beginners and experts to increase users' convenience in training steps. Then, we apply reinforcement learning policies according to users' groups. In the experiments, we evaluated the performance of the proposed method on the individual reinforcement learning policy and group's reinforcement learning policy.

Software globalization is becoming more important worldwide but little is known about how globalization technologies are actually carried out in the Korean software industry. In this paper, we have designed Globalization Quality Management (GQM) framework and applied the framework to the industry domestically for the first time. GQM provides a structured and effective way for software organizations to adopt globalization practices and evaluate the results. GQM consists of three main components: 1) software quality management process, 2) globalization support model and 3) globalization assessment model. This framework also supports both plan-driven and iterative/incremental development methods. On the basis of the GQM, a survey study was conducted among software engineering professionals, gathering the data from 31 IT companies across 7 large-scale projects in Korea. The result indicate that the evaluation score for globalization capability is 2.47 and global readiness is 2.55 out of 5 points. Also It said that internationalized product design (32.9%) and global/local product requirements analysis (28%) are needed to be taken care of first.

As creativity and problem-solving ability become core competencies, the main objectives of programming subjects in the elementary and secondary educational curriculum is 'computational thinking'. This goal can not be achieved at the level of understanding the characteristics of the programming language and the simple utilization abilities of the computer. The abilities to write algorithms and solve problems in real life situations using programming languages are required. In order to cultivate these abilities, the curriculum of the programming area was strengthened in the elementary and middle education curriculum, and the criteria for evaluating the achievement level were also prepared. However, the curriculum that can be used in actual education field is not yet established. In this study, we analyzed the researches on the existing programming curriculum and evaluated how well the curriculum meets the achievement criteria. Also, we can suggest the aspects to be considered in the study of programming curriculum and to verify whether the results of curriculum operation are in line with achievement criteria. In addition, future directions in elementary and middle school programming curriculum are suggested.
