Standard electronic tax invoice is a document standard for electronically exchanging tax invoices, which have been used in the form of paper for proofing business transactions. This standard focuses on the aspect of exchanging electronic documents between businesses and between businesses and NTS(National Tax Service), so it is limited in expressing semantics and contexts of financial information explicitly and economically for reusing them after their exchanges. Above all, it is needed to consider that they can be employed to various applications of businesses including financial reporting and auditing because they contain basic financial information about taxes and that they are reported to NTS. In this perspective, this paper compares and analyzes how to compose standard electronic tax invoice documents in XBRL with concrete examples, focused on the expressability and applicability, and discusses the possibility of XBRL-based standard electronic tax invoices.

Fuzzy neural network is an integrated model of artificial neural network and fuzzy system and it has been successfully applied in control and forecasting area. Recently ANFIS(Adaptive Network-based Fuzzy Inference System) has been noticed widely among various fuzzy neural network models because of outstanding performance of control and forecasting accuracy. ANFIS has capability to refine its fuzzy rules interactively with human expert. In particular, when we use initial rule structure for machine learning which is generated from human expert, it is highly probable to reach global optimum solution as well as shorten time to convergence. We propose metrics to evaluate interpretability of generated rules as a means of acquiring domain knowledge and compare level of interpretability of ANFIS fuzzy rules to those of C5.0 classification rules. The proposed metrics also can be used to evaluate capability of rule generation for the various machine learning methods.

The relational data model can't be applied to CAD/CAM, CE, and CIM since it can't support the semantic model concept such as complex object, random data definition, manipulation, version control, generalization, aggregation and so on. In this paper, the IPCS(Integrated Production Control System) for hand-rail of ship is parted into several module according to process function. further more, the object oriented data model is designed with UML(Unified Modeling Language). UML is the object oriented design methodology of industrial standard that combines the Booch's methodology, the Rumbaugh's On(Object Modeling Technique), and the Jacobson's OOSE(Object-Oriented Software Engineering) methodology. The efficient management is expected with object-oriented data model construction, since this developed system can achieve efficient process control, system maintenance, repair and extension.

In this paper, we develop the thinking extension education program for the gifted students of information, and prove the validity and effectiveness of the proposed model by presenting the Tic-tac-toe problem as the practical example of the information-gifted students. This model consists of four phases which has the game tree as data structure and the search of game tree as control structure. And the search of game tree becomes the basis of the thinking extension education program. This model gives the help for students to learn representing the problem as tree structure and solving the problem of tree structure using the search method of game tree. The internal ability of the information-gifted for thinking extension of this education program contains the fluency, perceptiveness, originality, power of concentration, imaginative power, analyzing skills, pattern recognition, space sense, synthesizing, problem-solving.

The volume ray-casting method is one of the direct volume rendering methods that produces high-quality images as well as manipulates semi-transparent object. Although the volume ray-casting method produces high-quality image by sampling in the region of interest, its rendering speed is slow since the color acquisition process is complicated for repetitive memory reference and accumulation of sample values. Recently, the GPU-based acceleration techniques are introduced. However, they require pre-processing or additional memory. In this paper, we propose efficient point-primitive based method to overcome complicated computation of GPU ray-casting. It presents semi-transparent objects, however it does not require preprocessing and additional memory. Our method is fast since it generates point-primitives from volume dataset during sampling process and it projects the primitives onto the image plane. Also, our method can easily cope with OTF change because we can add or delete point-primitive in real-time.

For the object-oriented development methods authorized by OMG a number of official methodologies such as Booch, Coad/Yourdon methods are used in the development of the object-oriented soft ware and each methodology represents its process of analysis and design using different symbols. Between those notation methodologies there exist some differences as a matter of development, information for transfer, accordingly they act on the transfer of the information in the object-oriented development as obstacle and give rise to they natural outcome of error. The aim of this study is in the presentation of ideas that decrease the probability of errors by means of verify8ing the transferring ability of information which the existing diagrammatic notation methodologies have had on the basis of cognitive science, minimizing the cognitive load from the object-oriented development through enhancing symbols in each obstacles to transferring information and removing them.

연구목적: 노인을 위한 건강정보 웹사이트들이 사용성과 접근성을 높이기 위해 지켜야 할 디자인 요소를 어떻게 반영하고 있는지 평가·비교함으로써 개선 방향을 제언하고자 하였다. 연구방법: 국내 및 미국에서 개발된 노인 대상의 건강정보 웹사이트를 각각 9개씩 선정하였다. 근거 기반의 웹디자인 지침서인 Make Your Website Senior Friendly: Checklist와 Research-based Web Design & Usability Guideline을 통합 수정하여 얻은 4개 영역의 평가 항목 48개를 적용해 두 명의 평가자가 선정된 총 18개 웹사이트를 평가하였다. 연구결과: '가독성' 영역 중 서체 선택, 줄 간격, 배경색과 글자색 선택 등은 양호하였으나 국내 웹사이트들 중에는 글자 크기가 조절되지 않는 경우가 빈번하였다. '정보의 표현과 구성' 영역에서 다수의 웹사이트들은 정보 배치 등이 우수하고 소비자 용어를 사용하는 노력을 보였다. 그러나 일부 국내 웹사이트들은 프린트 기능을 제공하지 않거나, 노인들의 저하된 인지 능력을 배려하려는 노력이 부족하였다. '미디어 사용' 영역에서 국내 웹사이트들은 글자 외에 다른 매체를 사용하는 빈도가 미국 웹사이트들에 비해 낮았고, 시청각 매체를 사용할 때는 동일한 내용을 문자로도 볼 수 있도록 하라는 권고안을 준수하지 않았다. '내비게이션과 검색의 용이성'에서는 메뉴나 링크의 명칭이 명확하며, 이용 중에도 쉽게 홈페이지로 돌아갈 수 있도록 구성되었다. 그러나 다수의 국내 사이트들이 사이트맵을 제공하지 않거나, 검색어의 철자오류 등에 대한 배려가 부족하였다. 결론: 국내 웹사이트들은 미국 웹사이트들에 비해 노인들의 사용성과 접근성을 높이는 것으로 밝혀진 연구 근거들을 제대로 반영하지 못하고 있었다. 노인 대상의 인터넷과 웹을 활용한 교육이 지속적으로 증가할 것이므로, 그 효과성을 높이기 위해 간호사들은 정보의 질 뿐만 아니라 디자인 측면의 중요성을 인식하고 실천할 수 있어야겠다.

When elementary students write their own sentences, it is often educationally beneficial to compare them with other people's similar sentences. However, it is impractical for use in most classrooms, because it is burdensome for teachers to look up all of the sentences written by students. To cope with this problem, we propose a novel approach for automatic selection of similar sentences based on a three-step process: 1) extracting the subword units from the word-level sentences, 2) training the model with the encoder-decoder architecture, and 3) using the approximate k-nearest neighbor search algorithm to find the similar sentences. Experimental results show that the proposed approach achieves the accuracy of 75% for our test data.
