Purpose - The purpose of this study is to present a framework for determining the most appropriate business model for e-learning. Research design, data, and methodology - The Electronics Branch of Azad University has been elected as a case study in this research. This study conducted using a descriptive method. The information was obtained using interviews with experts including managers, faculty and students at the Electronics Branch of Azad University. Results - Three service-product system (product oriented system, use an oriented and result oriented system) approaches determined a framework for the formation of a portfolio. This portfolio is including three types of e-learning business models. Examining the relevant characteristics, correspondence of behaviorism learning theory with a product-oriented approach, correspondence of cognitivism theory with a user-oriented approach and in finally match correspondence of constructivist learning theory with a results-oriented approach which is evident. Conclusions - After reviewing the literature on the fields of e-learning, business model and product - service systems, we have achieved three types of e-learning business models. Then the variables in any of the business models were defined by using business model canvas tool and thus a portfolio consisting of three types of e-learning business model canvas was obtained.

기업이 특정 업무를 처리하기 위해서 자체적으로 개발하여 사용하고 있는 응용 소프트웨어의 신뢰성을 평가 방법은 시스템의 설계방법에 따라서 많은 차이가 있다. 그러나 이 많은 방법들에서 대부분은 모수를 추정하는 방법이 최후추정법을 적용하여 모형을 개발하는 과정을 거치다보니 복잡하여 현장에서 사용하기는 매우 어렵다. 그래서 본 연구에서는 간편한 모수추정방법을 개발하여 현장 적용이 용이한 모형을 개발할 수 있는 간단한 모수추정방법에 대해서 연구하고자 한다. 만약, 이렇게 되면, 현장에서 응용 소프트웨어 시스템을 개발할 때, 신뢰성을 평가해 보고자하면 바로 사용할 수 있는 모수추정방법이기 때문에 매우 유용하게 사용될 것으로 기대한다. 그리고 이 모수추정방법의 정확성을 검정하기 위해서 기존 모수추정방법으로 신뢰성 평가모형을 구해 비교 평가함으로서 개발된 모수추정법의 간편함을 입증하고자 한다.

최근 딥러닝 기술이 빠르게 발전함에 따라 국가 R&D 분야의 방대한 텍스트 문서를 다양한 관점에서 분석하기 위한 수요가 급증하고 있다. 특히 대용량의 말뭉치에 대해 사전학습을 수행한 BERT(Bidirectional Encoder Representations from Transformers) 언어모델의 활용에 대한 관심이 높아지고 있다. 하지만 국가 R&D와 같이 고도로 전문화된 분야에서 높은 빈도로 사용되는 전문어는 기본 BERT에서 충분히 학습이 이루어지지 않은 경우가 많으며, 이는 BERT를 통한 전문 분야 문서 이해의 한계로 지적되고 있다. 따라서 본 연구에서는 최근 활발하게 연구되고 있는 추가 사전학습을 활용하여, 기본 BERT에 국가 R&D 분야 지식을 전이한 R&D KoBERT 언어모델을 구축하는 방안을 제시한다. 또한 제안 모델의 성능 평가를 위해 보건의료, 정보통신 분야의 과제 약 116,000건을 대상으로 분류 분석을 수행한 결과, 제안 모델이 순수한 KoBERT 모델에 비해 정확도 측면에서 더 높은 성능을 나타내는 것을 확인하였다.

최근 가짜 뉴스가 분야를 막론하고 전 세계에서 주목을 받고 있으며, 현대경제연구원에서는 이러한 가짜 뉴스로 인한 피해 규모가 연간 약 30조 900억원에 달하는 것으로 추산하였다. 정부에서는 "가짜 뉴스 찾기"를 주제로 "인공지능 R&D 챌린지" 대회를 개최하여 가짜 뉴스를 가려낼 인공지능 원천기술 개발에 대한 첫 걸음을 내딛고 있으며, 민간 차원에서도 다양한 분야에서 팩트 체크 서비스가 제공되고 있다. 학계에서도 가짜 뉴스를 탐지하기 위한 시도가 전문가 기반, 집단지성 기반, 인공지능 기반, 시맨틱 기반 등으로 활발하게 이루어지고 있다. 하지만 이러한 시도는 조작의 정밀도가 높을수록 뉴스 자체에 대한 분석만으로 진위 여부를 식별하기가 더욱 어렵다는 한계를 경험하고 있으며, 가짜 뉴스 탐지 모델의 정확도가 과평가된 경향을 보이고 있다. 따라서 본 연구에서는 가짜 뉴스 탐지 모델 정확도의 공정성을 확보하고, 뉴스의 내용뿐만 아니라 해당 뉴스에 대한 반응으로 자연적으로 발생한 광범위한 소셜 데이터를 활용하여 뉴스의 진위 여부를 판정하는 방안을 제안하고자 한다.

Recently, RFID technology has attracted considerable attention in many industry fields. The RFID environment requires a standard architecture for the smooth exchange of data between heterogeneous networks. The architecture should offer an efficient standard environment, such as a communication environment based on Web Services, PKI or Kerberos-based security, and abstract business processes which could be used in the diverse domains. Therefore, in this paper, we propose an Enterprise Application Framework (EAF) which includes a standard communication protocol, security functions, and abstract level business processes. The suggested architecture is expected to provide a more secure and flexible security management in the dynamic RFID application environments, and is expected to provide an abstract business event for the development of business processes which could apply RFID technology to the existing systems.

Clustering is one of the leading methods to analyze big data and is used in many different fields. This study deals with Clustering Validity Index (CVI) to verify the effectiveness of clustering results. We compare the performance of CVIs with business applications of various field. In this study, the used CVIs for comparing performance are DU, CH, DB, SVDU, SVCH, and SVDB. The first three CVIs are well-known ones in the existing research and the last three CVIs are based on support vector data description. It has been verified with outstanding performance and qualified as the application ability of CVIs based on support vector data description.

The purpose of this study is to empirically analyze whether open innovation activities are significant and which methods are more effective in developing new businesses. Based on the latest technological innovation survey data of the Science and Technology Policy Institute, the results were analyzed by binary logistic regression analysis. As a result of the analysis, we confirmed that open innovation activities have a positive effect on the performance of developing new businesses. In the open innovation activities, Recruitment (invitation) of specialist in related fields, Business alliance technical agreement, Dispatch of personnel, M&A, Acquisitions identify related field trends showed more influence in order. It would be beneficial to improve the performance of developing new businesses with a low probability of success if utilize more effective innovation activities in developing new business in enterprises or organizations throughout this study.

Recently, knowledge management and E-business are very important issues in academic and business fields. Research questions related with these issues are which factors stimulate knowledge management. Another question is whether knowledge management is related to E-business. To answer these questions a research model was proposed. The data were collected from 90 manufacturing firms in Korea. Appropriate research methodologies were employed for analysis. Results found that the degree of firm's internalization, diversity of domestic management activities and learning orientation affect knowledge aquisition and transfer. Knowledge aquisition and transfer facilitate knowledge application, resulting in new product development, cost reduction and technology differentiation. Knowledge management is a kind of process. This result, therefore, confirms what previous literature predicted.

With the 4th industrial revolution, many advanced information technologies are being applied to the area of construction engineering and project management. These applications are usually focusing on design, construction and operation stage and are producing many meaningful fruits. Even though these studies are very important for the development of the construction industry, this study insists that the other stage perspective such as construction business also should be emphasized. Because business phase has significant impacts on the success of a construction project as well as design, construction and operation phase. So, this study reviewed the intelligent-approach papers in planning and marketing, estimation and bid, contract and claim, and project financing fields. This study provides some insights such as values, difficulties, limitations and future directions of business intelligence application.

This study aims to explore the ways of reinforcing the competitive edge and substance of company through e-business in furniture industry by presenting the e-business model of furniture industry which faces the opportunity of challenge in the course of industrial restructuring. e-business model can take various types depending on the environment, feature and competitive edge that each company faces. For example, it is general in the fields of manufacturing company to study the model by dividing into Sell Side for sales to the customers, and Buy Side for purchase of raw materials, Integrating both sides. In furniture industry, Sell Side has the feature of giving a priority in the quality and price rather than brand image in the purchase type of consumer. Especially, it shall not be overlooked that majority of furniture is delivered to the consumer indirectly through the construction company. As such, e-business should be promoted in a way to expand the point of contact for consumers, rather than to construct its own point of contact for consumers. The percentage of importation of raw lumber is high and the standardization was insufficient in Buy Side.
