Computer programming education gives students a chance to use computers independently and actively. This plays a very positive role in acquiring higher cognitive skills such as mathematical skills and creative logical thinking. Thus the purpose of this study is to measure the degrees of students' problem-solving abilities using MCU programming kits based on the ICT Education Guide. The experiment confirms that programming classes using MCU kits have a more positive effect on the students problem-solving abilities than do those using the existing computer textbooks. The sub-constituents of problem-solving abilities - problem recognition, information gathering, analysis, diffuse thinking, decision-making, planning, execution, evaluation and feedback - also show significant statistical differences. Therefore, we can conclude that programming classes using MCU kits are very effective in advancing problem-solving abilities.

In the year of 1980 and 2000, the Korean government institutionalized the Value Engineering methodology in the construction phase and the design phase respectively. While design-phase VE have been applied to construction industry actively, which was institutionalized 7 years ago, construction-phase VE have not been applied to industry frequently, although it was institutionalized 25 years ago. On the other hand, at the time of social demands for VE is increasing, it has been pointed out that VE should be compatible with the delivery system. And the time of VE study, the operational management of VE study, and the maintenance process of the result of the VE study also should be considered. In this study, a scheme to improve VE methodology in the construction industry is proposed based on the literature review and the data analysis of domestic and foreign state of VE.

Firewall은 다양한 부정Access의 방지책으로서 확실히 유효한 수단이지만 이 Firewall은 사용자로부터 지시된 설정을 충실히 실행하는 것으로 설정 오류, 소프트웨어의 정지, 허가된 룰을 악용한 침입 등 반드시 사용자가 바라는 작용을 무조건적 상태에서 보증해 주는 것은 아니다. 따라서 사용자는 도입 후 에도 운용시에 Access log를 감시하고 본래의 Security Policy에 반하는 행위를 매일 매일 체크하지 않으면 안될 상황에 처해 있다. 본 연구는 이러한 부정Access에 대한 이와 같은 Firewall의 현상에 대한 과제 중에서 "부정Access를 어떻게 하면 일찍, 정확히 체크할 수 있는가\ulcorner"라는 주제를 선택하여 Firewall의 한계와 그 대응책을 실제로 부정Access를 시험해 보는 것으로 검증하기로 하였다. 실험결과에서 (1)Port Scan이나 전자메일 폭탄(서비스정지공격)등은 Firewall로 방지하는 것은 불가능하거나 혹은 Checking이 곤란하다. (2)공격마다 로그 수집을 했음에도 관계없이 Firewall의 로그는 번잡하므로 단시간에 사태의 발견이 대단히 곤란하다고 하는 Firewall의 한계를 인식하였다. 그리고 그 대책으로서 우리는 체크 툴의 유효성에 착안하여 조사한 결과, 결국 무엇이 부정Access인가에 대해서는 어디까지나 이용하는 측이 판단하여 Firewall 상에 설정하지 않으면 안되지만 체크 툴은 이 부정Access 정보를 데이터베이스로서 갖고 있음으로써 '무엇이 부정Access인가'를 이용자 대신에 판단하고 툴에 따라서는 설정을 자동적으로 변경하여 부정 Access의 저지율을 향상시킨다. 이처럼 체크 툴은 Firewall의 수비능력을 보강하는 위치에 있다고 생각할 수 있다.다. 4 장에서는 3장에서 제기한 각각의 문제점에 대해 RAD 의 관점에 비추어 e-business 시스템의 단기개발을 실현하기 위한 고려사항이나 조건 해결책을 제안한다. 본 논문이 지금부터 e-business 를 시작하려고 하는 분, e-business 시스템의 개발을 시작하려고 하는 분께 단기간의 e-business 실현을 위한 하나의 지침이 된다면 다행이겠다.formable template is used to optimize the matching.

As a result, conventional NN and CNN were available for interpolation of sampling data. Moreover, when nonlinear intensity is not so large under the field condition of small slope, interpolation performance of CNN was a little not so better than NN. However, when nonlinear intensity is large under the field condition of large slope, interpolation performance of CNN was relatively better than NN.콩과 자연 콩이 성분 분석에서 차이를

These days information technology and internet have made startling progress. In these developing environments, the strategy or marketing based on existing off-line is getting more difficult to accomplish the role of the improvement of business competitive power, and they are bringing out a lot of changes in information management and marketing performance method about consumers due to digital networking between companies and consumers. These developments and changes make many varieties in the way of design studying methodology. Therefore, in this study, considering the aspects of design, society and environment, after I developed the consumer response framework about products design which is argued by Bloch(1995) ; distinct relationship model among preference degree- design image adjective - design factors, we established design information abstraction solution combined with the interaction based on IT as eCRM in real time. This suggested solutions will provide product designers with good information in finding the design factors which consumers prefer.

재난은 인류의 발전과 더불어 다양하게 발생되어왔다. 최근 21세기 들어 발생하는 재난은 그 현상이 더욱 다양하고 복잡하며 그 피해의 정도가 대규모로 진행되는 경우가 많아 졌다. 태풍, 집중호우, 강풍, 폭설, 지진, 황사 등의 자연재난은 지구온난화현상으로 국내뿐만 아니라 전 세계적으로 커다란 영향력을 미치고 있으며, 화재, 구축물의 붕괴, 지하철사고, 테러 및 감염병 등의 사회 재난도 더욱더 증가하고 있는 추세이다. 나아가 사스, 메르스, 지카 바이러스 및 대형 테러 등 전 세계적 차원의 사회 재난의 발생 또한 급증하고 있다. 이와 같이 현대사회에서 발생하는 재난는 개인이나 국가의 정책만으로 예방하고 관리할 수 없는 특성이 있다. 따라서, 자본주의 경제의 한축을 이루고 있는 기업의 재난을 관리하여 연속성을 확보하고 더나아가 리질리언스(Resilence)를 보장하기 위한 일환으로 2007년 7월 재해경감을 위한 기업의 자율 활동 지원에 관한 법률(이하, 기업재해경감법 이라함.)이 공포된 지 약 10여년이 경과하였다. 이는 법 제도화를 통하여 기업의 재해경감활동을 지원하기 취지에서 출발한 것 이다. 그 후 현재 까지 어느 정도의 발전이 있었지만 경과 년 수에 비해 아직 미흡한 실정이다. 이후 그 기업들이 좀 더 원활하게 재해경감활동을 위한 계획을 수립, 실행, 검토 및 유지하기 위한 지침으로서 기업재난관리표준을 2010년 4월 2일 제정하였고 이후 재해경감활동 수립계획을 제정하여 시행하기에 이르렀다. 또한, 기업재난관리표준은 제정된 이후 2013년 12월 9일 전면 개정작업을 통해 경영관리 프로세스 모델(Plan-Do-Check-Act)이 적용된 관리체계를 접목시키고 용어정의를 국제표준과 일치시켜 기업재해경감활동 상의 혼선을 방지하기 위한 노력을 하였다. 현 정부에서는 주무부처가 바뀌고 조직이 변화되어 행정안전부고시 제2017-1호(2017.07.26.일)로 개정되어 현재에 이르고 있다. 본 논문에서는 기업재난관리표준과 연관된 제반 법령 및 규정 등에 대한 법적성격 과 지위를 규명하고, 기업재난관리표준의 관련분야 적용 시 문제점 및 바람직한 제도개선 방향을 제시하고자 한다.

ARS (Automatic Response Systems) based on VUI (Voice User Interface) and TTI (Touch Tone Interface) are one of the most widely used communication systems. Despite common usages, however, inconvenience of ARS is continually pointed out. This may stem from lack of human-centered studies aside from technological development. In this paper, we provide guidelines for designing ARS by analyzing hindrance factors of usability of ARS menu structure. We had selected two call-centers using ARS, and carried out an experimental study where subjects performed the task of "returning books." After that, they completed questionnaires and interviews. We identified four problems: the complex menu structure, lack of representativeness on the menu name, users' awareness of location, and a difficulty to move among menus. And we partially discussed the ways of avoiding the problems.

The objective of this research is to measure the quality of web accessibility of Tripitaka Koreana websites. To achieve this research aim, three typical websites were selected, and conducted both the system-based evaluation and the user-based evaluation using the six common indicators. It found that no website satisfied with the 95% accessibility level in all six indicators, and users were more likely to respond positively to the high level of web accessibility results from the system-based evaluation (i.e., providing alternate texts, providing titles, displaying the basic languages, performing user requests, and providing labels). We suggested some ideas to increase the web accessibility based on the results of analysis.

As the more web contents are available through the internet, relative importance of electronic resources in the library collection has gradually increased. While several measurement criteria are used for the effective collection development, the usage statistics is generally accepted as the key factor to assess the retention and cancellation of electronic resources. In this paper it was examined the roles and problems inherent in the electronic journals usage statistics, and then the quality of electronic journal usage reporting services provided by several publishers were evaluated, following the ICOLC and COUNTER guidelines. To apply the usage statistics of electronic journal on the library collection development, it is necessary that libraries, related association and publishers accomplish more consistent and practical usage statistics components. And it is recommended that publisher and aggregator accommodate the guideline for electronic journal usage report.

We analyzed the responses of 152 science-gifted high school students by surveying the status and recognition of writing and keeping laboratory notebooks to develop guidelines and education plans. Science-gifted students did not write laboratory notes diligently, despite recognizing that it is crucial to do so. Mentors also tended not to provide faithful guidance and inspection. There was an insufficient practice in using research evidence in laboratory notebooks, such as including names and dates for authentication. In addition, while a high ratio of students owned their own laboratory notebooks, there was not a high level of recognition regarding the retention period, ownership, and responsibility. Based on these results, we propose suggestions for improving educational institutions for gifted students in science. First, it is necessary to strengthen the guidance for science-gifted students to faithfully write laboratory notebooks. Second, education on writing laboratory notebooks should be provided. Third, science-gifted high schools should prepare regulations for the management of lab notes and conduct education based on them.
