New technology development capability plays a key role in making small- and medium-sized enterprises (SMEs) increase their innovation performance, such as in product or process innovation. To examine the influencing factors of SMEs' new technology development capability, this study empirically analyzes the mediating effects of SMEs' process design capability and product interior design capability on the positive association between their external information network diversity and new technology development capability. This study performs the ordinary least squares regression on a sample of 2,000 South Korean SMEs. Results reveal that SMEs' process design capability fully mediates, and product interior design capability partially mediates the positive association between the external information network diversity and new technology development capability.

A contingency model of outsourcing is developed from the information systems (IS) literature and strategic management literature in order to assess the following question: What factors influence change in the extent to which an organization outsources IS functions? Based on the literature, this study identifies four IS factors-gaps in information quality, IS support quality, IS staff quality, and IS cost effectiveness-and three organizational factors-the gap in financial performance, strategic orientation, and the role of information technology in an organization-that influence the change in degree of outsourcing. These factors are hypothesized to influence the change in the extent of an organization's outsourcing of IS functions. From a mail survey of 188 top IS executives in U.S. companies, the results of analysis of covariance and bivariate correlational and multivariate regression analyses provide the following major findings: (a) This study found support for the proposed research model. (b) The change in the degree of IS outsourcing is determined by gaps in information quality, IS support quality, IS cost effectiveness, and financial performance and by the role of IT among IS and organizational factors.

의미역 결정 작업은 서술어와 문장 내 행위자, 피행위자, 장소, 시간 등 서술어와 관련 있는 논항들을 추출하는 작업이다. 기존 의미역 결정 방법은 문장의 언어학적 특징 추출을 위한 파이프라인을 구축하는데, 파이프라인 내 각 추출 작업들의 오류가 의미역 결정 작업의 성능에 영향을 미치기 때문에 현재는 End-to-End 방법의 신경망 모델을 이용한 방법들이 제안되고 있다. 본 논문에서는 의미역 결정 작업을 위해 Biaffine Average Attention 구조를 이용한 신경망 모델을 제안한다. 제안하는 모델은 기존 연구에서 제안된 특정 시점에 대한 레이블 예측을 위해 주변 시점 정보를 이용하는 LSTM 모델 대신 문장 내 서술어와 논항의 거리에 상관없이 문장 전체 정보에 집중할 수 있는 Biaffine Average Attention 구조로 이루어져 있다. 제안하는 모델의 성능 평가를 위해 F1 점수를 이용하여 기존 연구에서 제안한 BERT 기반의 모델들과 비교하였으며, 76.21%의 성능으로 비교 모델보다 높은 성능을 보였음을 확인하였다.

정보 기술의 발달로 시스템의 규모는 대형화되고 역할의 종류도 다양해져서 기존의 역할기반 접근제어로는 확장성, 호환성, 복잡성 등의 한계에 부딪히게 되었다. 블록체인 기술은 기존 보안 취약점에 새로운 해법을 제시하며 다양한 분야에서 활용되고 있다. 본 논문에서는 저장소의 접근 빈도와 저장 용량에 따라 요구되는 가스 및 처리 시간이 달라지는 블록체인 환경에서 효율적인 역할기반접근제어를 제안하였다. 제안하는 방식은 재사용 가능한 단위의 역할을 재정의하고, 동적인 상태를 효율적으로 반영할 수 있는 계층적 구조를 도입하여 복잡성을 해결하고 효율성 및 확장성을 강화하였고, 암호화폐 연동이 가능할 수 있도록 사용자 중심의 인증기능을 포함하였다. 제안하는 모델은 마르코프체인을 이용하여 이론적으로 먼저 검증하고, 이더리움 프라이빗 네트워크에서 구현하여 대표함수에 대한 비교 실험을 실행하여 사용자 추가 및 트랜잭션 등록 시에 요구되는 시간과 가스 효율성에 대하여 검증하였다. 향후 이를 기반으로 예외 상황 등을 고려한 구조 확장 및 실험 등이 요구된다.

The main purpose of this study intends to study the theoretical interconnection between human response capability and customer relationship management advantage while considering the essential role of service application of information technology as direct, indirect (mediating), and interactive (moderating) influences in the theory. Based on the study sample, the new findings help comprehend the overall interconnected relationship which includes the direct and indirect (mediating) effects of information technology service capability and human response capability as well as their interaction (moderation) on customer relationship management advantage. The new insights interprets the two capabilities (human and information technology) are vital to business because they are the foundation set of service resources significantly to enhance customer relationship management advantage.

This study proposes a method for investigating current patents related to information communication technology and smart mobility to provide insights into future technology trends. The method is based on text mining clustering analysis. The method consists of two stages, which are data preparation and clustering analysis, respectively. In the first stage, tokenizing, filtering, stemming, and feature selection are implemented to transform the data into a usable format (structured data) and to extract useful information for the next stage. In the second stage, the structured data is partitioned into groups. The K-medoids algorithm is selected over the K-means algorithm for this analysis owing to its advantages in dealing with noise and outliers. The results of the analysis indicate that most current patents focus mainly on smart connectivity and smart guide systems, which play a major role in the development of smart mobility.

Community enterprise plays an important role for developing local business. Products from local communities apply local specialties such as high-quality materials and inherited wisdom. This work aims to support merchandises from local community enterprises by bringing out their specialties related to local wisdom and intangible cultural aspects. An ontology is applied to demonstrate the innate information regarding the implicit values of the products and is used as a core for a semantic search system. Details of the products are gathered from their respective community using an interview method and are extracted to align with the developed ontological schema. The semantic search system thus is implemented with a recommendation process for online accessibility for providing the organised information. From evaluation, the developed ontology and its instances are rated highly for their consistency, conciseness, and completeness. In usage, accuracy of the query and recommendation results are evaluated at 97.38% searching accuracy and 85.03% for recommending interesting products.

정보와 미디어 집약적인 21세기 게임 환경에서 디지털 리터러시 스킬과 비판적 역량의 활용은 점점 더 중요해지고 있다. 이 연구는 공상 과학 판타지를 주제로 한 대규모 멀티 플레이어 온라인 롤 플레잉 게임 (MMORPG)인 와일드스타(WildStar) 참여자들의 디지털 리터러시 활용 관행에 대해 탐구하고 설명한다. 활동적인 역할 참여자는 게임 내부의 특정한 역할을 가지고, 그룹 중심의 대화형 스토리를 만드는데 적극적으로 참여한다. 역할 참여자가 어떻게 정보, 미디어 및 기술을 찾고, 사용하고, 평가하고, 관리하는지 잘 이해하기 위해, 이 연구는 광범위한 역할 참여자 관찰 데이터, 위키페이지나 토론게시판의 글과 같은 참여자들의 커뮤니티 활동을 보여주는 데이터, 그리고 17 명의 참여자들을 대상으로 한 반구조화 면담 데이터를 통합 분석한 하이브리드 민족지학적 방법을 사용하였다. 참여자들은 다양한 미디어와 기술을 사용하여 롤 플레잉을 보완하고 단순화시키면서, 더욱 몰입적인 롤 플레잉을 만들었다. 개인별 디지털 리터러시 수준은 상대적으로 상이하고, 참여자들은 더 유능하고 경험 많은 커뮤니티 구성원의 기술에 의존하기도 했다. 온라인 게임의 특성과 롤플레잉의 교육적 효과를 고려한 디지털 리터러시 교육과 도서관 프로그램의 영향과 적용 방안에 대해서도 논의하였다.

A well-designed computer network technology produces benefits on several fields within the organization, between the organizations(suborganizations) or among different organizations(suborganizations). Network technology streamlines business processes, decision process. Graphs are useful data structures capable of efficiently representing a variety of networks in the various fields. Metagraph is a like graph theoretic construct introduced recently by Basu and Blanning in which there is set to set mapping in place of node to node as in a conventional graph structure. Metagraph is thus a new type of data structure occupying its popularity among the computer scientists very fast. Every graph is special case of Metagraph. In this paper the authors introduce the notion of Meta-Networking as a new network technological representation, which is having all the capabilities of crisp network as well as few additional capabilities. It is expected that the notion of meta-networking will have huge applications in due course. This paper will play the role of introducing this new concept to the network technologists and scientists.
