본 연구는 비구조화된 문제해결모형을 적용하여 수업을 하는 과정에서 나타나는 학생들의 의사결정과정을 관찰 분석함으로써 초등학교 현장에서의 비구조화된 문제 적용 가능성을 제시하고자 한다. 이를 위해 서울 소재 C초등학교 5학년 학생 25명을 대상으로 확률과 통계영역 중 자료분석에 관한 비구조화된 문제를 제시하였고, 문제해결은 ABCDE(Analyze - Browse - Create - Decision Making - Evaluate) 모형을 적용하여 의사결정단계(자신의 견해 확립하기, 타인의 견해 검토하기, 문제해결에 적절한 견해를 결정하고 실행하기)에서 나타난 학생들의 의사결정과정을 분석하였다. 총 여섯 모둠 중 비구조화된 문제해결모형에 따라 수업진행이 비교적 잘 이루어진 상위 두 모둠은 문제에 대한 서로의 생각과 의견을 활발하게 나누며, 3단계의 의사결정과정이 모두 나타났다. 학생들의 고차원적인 문제해결력 향상을 위한 심화된 문제의 해결이 요구되는 현 상황에서, 비구조화된 문제의 개발 및 적용을 통해 학습자의 문제 해결의 가능성을 기대해 볼 수 있겠다.

Objectives : The Dongui Bogam in My Hand', which is an output of computerizing Donguibogam (Principles and Practice of Eastern Medicine), is an interim outcome of the research project led by the Korea Institute of Oriental Medicine. This study examined the process in which Donguibogam, a record in Chinese and a classic of Oriental medicine, expanded into a modern content. Methods : This study will classify the modernization of Donguibogam into three 'contents' that form Donguibogam, 'container' that will hold the contents, and 'community' that is the consumer of Donguibogam. Towards the end, this study will sketch out the status of computerizing Chinese records in Korea, and point out the reality faced by computerization of ancient documents on Oriental medicine as well as the direction for the future. Results : 'The Dongui Bogam in My Hand' has been downloaded more than 10,000 times for 4 months since it releases in August 2014, and is used for at least 6,000 times on average every month. This achievement can be due to the two following reasons. First, the application contains high-quality contents such as the original text of Donguibogam as well as Korean and English translations. Second, it satisfied the needs of Donguibogam users with (1) the Browse function that well displays the table of contents, (2) the Search function that separates the title from the main text, and (3) the Personalization function designed to link and share relevant knowledge. Conclusions : Computerization of Chinese records was triggered by the request of the academia, but it was accelerated after being selected as a public laboring project to overcome the IMF crisis. However, computerization of ancient documents is not a simple task but a field of study to modernize classical knowledge. The success or failure of computerization of Chinese records is determined by whether high-quality modern 'contents' are secured, whether the 'container' design adequately implements the search, browse and link functions, and how well it fulfills the needs of the consumer 'community'.

The number of cellular phone users has exceeded over twenty million recently. Some researches show that people in the twenties to thirtieth usually regard the cellular as an instrument for not only call but also Internet. It means the cellular is being highlighted as a mediator for transmitting information. Therfore it'll play an essential role soon as a gateway for unifying wire and wireless services if we can browse Internet sites, for example our own homepage or commercial site, with the cellular. This paper explain WAP topology which enable the mobile terminal to access to the Web and show a method of designing and realizing WML document on the Web.

ebXML is the international technical framework specification that enables Internet-based B2B electronic business using XML, It was standardized by UN/CEFACT and OASIS on May 2001. Registry and Repository is the core of ebXML. It supports registry services which is composed of object management service and object query management service. The object management service manages the object's life cycle and the object query management service provides a mechanism to approach metadata of stored objects. Up to now, implementations of ebXML Registry object query management system don't support full functions of the specification completely. We implemented all the functions of ebXML Registry Service Specification vl.0. This system supports Browse ＆ Drilldown Query, Filter Query, SQL Query, and Object Retrieval Query services. And it also supports Content-based Query service which is not specified in the ebXML RS specification. The Content-based Query service is a repository service which makes it possible In pose content based queries of repository items and which will be specified on the RS specification v2.0.

This paper presents an implementation of a gesture recognition platform that can be used in a factory workplaces. The platform consists of signages that display worker's job orders and a control center that is used to manage work orders for factory workers. Each worker does not need to bring work order documents and can browse the assigned work orders on the signage at his/her workplace. The contents of signage can be controlled by worker's hand and arm gestures. Gestures are extracted from body movement tracked by 3D depth camera and converted to the commandsthat control displayed content of the signage. Using the control center, the factory manager can assign tasks to each worker, upload work order documents to the system, and see each worker's progress. The implementation has been applied experimentally to a machining factory workplace. This flatform provides convenience for factory workers when they are working at workplaces, improves security of techincal documents, but can also be used to build smart factories.

In this paper, a user-friendly mobile photo album system and albuming functions to support it are introduced. Stand-alone implementation in a mobile device is considered. The main idea of user-friendly photo browsing for albuming functions is to enable users to organize and browse their photos along semantically meaningful axes of events, personal identities, and categories. Experimental results demonstrate that the proposed method would be sufficiently useful and efficient for browsing personal photos in mobile environment.

무선 PDA.휴대폰을 통해 웹을 탐색하려는 이용자들은 인터페이스 상의 문제 때문에 어려움을 겪는다. 단지 그래픽을 문자로 바꾸거나 기호체계를 재구성한다고 해서 해결될 문제가 아니다. 심층 연계 구조를 통과하는 데에는 많은 시간이 걸리기 때문이다. 이러한 문제들을 해결하기 위해서 본 논문에서는 실시간의 최단경로를 제공하기 위하여 무선 웹 탐색을 자동적으로 개선시키는 Minimal Path 알고리즘을 제안한다. 본 논문의 결과 Minimal Path 알고리즘은 웹 이용자들에 대해 지름길을 제공해 주며, 링크의 숫자가 가장 짧았음을 알 수 있었다.

This study was conducted to compare the intake, digestibility and utilization of nitrogen by goats consuming high and low tannin diets. Low tannin diets were 100% grass(GS) and 50% grass + SO% alfalfa (GA), and high tannin diets were 50% grass + 50% lespedeza(GL) and 50% grass + 50% oak browse(G0). Dry matter intake did not differ among all diets, but digestibility of dry matter, cellular constituents, NDF and ADF showed slightly lower for high tannin diets(GO) than low tannin diets(GS and GA), but those were not differ between GL and low tannin diets with the exception of ADF digestibility. Total faces and urinary N were lower for high tannin diets than for low tannin diets. Apparently digested N was high in GA diets, but low in GO diets(P

As Information society evolves, there is a growing need that substitutes agents for users to do the given Jobs in distributed computing environments. Agents can retrieve and browse the diverse information via Internet, as the users request, and can deal with the complicated routine jobs on behalf of users with timeliness and efficiency. Especially, mobile agent can support the paradigm for distributed application programs in Internet environments. This is suitable to jump-to-jump model without any hesitations because agent moves. Agents can be applied to various applications, but we restrict it to market information retrieval in this paper. On recognizing a query about merchandise information by an user, agent by itself retrieves the corresponding information by navigating the Internet and informs the result to the user. In this paper, we review the mobile agent configuration to do this kind of work, propose the system architecture based on this review. By using this system, users can be free from complicated routine jobs and pursue his/her wishes to promote ones welfare.

정보교육의 궁극적 목적은 문제해결능력을 향상하는 것이며, 그 기반에는 Computational Thinking(CT)이 있다. 현 초등교육에서는 독립된 정보교과가 없기 때문에, 초등수학과 교수 학습장면분석을 통해 CT의 하위요소 적용 사례를 찾아본다면 CT 활용의 시사점을 얻을 수 있을 것이다. 본 논문에서는 CT의 하위사고틀의 관계를 밝히고 문제 해결을 위한 초등수학과 교수 학습의 장면 분석을 통해 CT의 활용을 고찰해 보았다.
