Competitive aggressiveness has long been believed to be the direct trigger for increased business performance, however, as a mediating variable it still needs to be further proven. This paper aims to examine the causal relationship between network capability, knowledge creation, innovativeness, competitive aggressiveness, and business performance of private universities. One model is proposed to test the role of competitive aggressiveness as a mediating variable. The population is lecturers at the 10 best private universities in East Java, Indonesia. Analysis by SEM, on 230 respondents, using random sampling method. The results show that the model is accepted, and competitive aggressiveness is proven to be a positive mediating variable in the relationship of network capability, knowledge creation, innovativeness, and business performance. The results also show that knowledge creation, and innovativeness, have an effect on competitive aggressiveness, while network capability has no effect. The research implication is that management should encourage lecturers and organizations to be more productive in conducting research and writing articles published in reputable journals, this will increase the ranking of universities. In order for the lecturers be more enthusiastic, the management gave an award to each lecturer who could submit their articles, which were then published by reputable journals.

Causality mining in NLP is a significant area of interest, which benefits in many daily life applications, including decision making, business risk management, question answering, future event prediction, scenario generation, and information retrieval. Mining those causalities was a challenging and open problem for the prior non-statistical and statistical techniques using web sources that required hand-crafted linguistics patterns for feature engineering, which were subject to domain knowledge and required much human effort. Those studies overlooked implicit, ambiguous, and heterogeneous causality and focused on explicit causality mining. In contrast to statistical and non-statistical approaches, we present Bidirectional Encoder Representations from Transformers (BERT) integrated with Multi-level Feature Networks (MFN) for causality recognition, called BERT+MFN for causality recognition in noisy and informal web datasets without human-designed features. In our model, MFN consists of a three-column knowledge-oriented network (TC-KN), bi-LSTM, and Relation Network (RN) that mine causality information at the segment level. BERT captures semantic features at the word level. We perform experiments on Alternative Lexicalization (AltLexes) datasets. The experimental outcomes show that our model outperforms baseline causality and text mining techniques.

Purpose The purpose of this study is to improve the efficiency of the activities of loosely connected network organization through the platform(Ba) of knowledge sharing. Loosely connected network organizations have been tried to promote new work and complement the scarce resources through collaborations. NPO(Non-Profit Organization) is essential to establish cooperation networks in order to achieve the public interest on the basis of scarce resources. This study interpreted the Ba on the 'Change-On' program and analyzed the social networks of regional organizations through the activation of the Ba. The 'Change-On' program is conducted for several years to promote the efficiency of the NPO network by Daum Generation Foundation. Design/methodology/approach This study made a design to organize the Ba concept of Nonaka & Konno and presented a case of the Ba activated based on the NPO network of regional order. According to the social network analysis of regional cooperation within the network of participating organizations was extended, it was found that the principal plays a significant role as a central hub made. Findings According to the empirical analysis, this study illustrated that various types of network were formed among NPOs based on the 'Change-On'. Furthermore, the networks surrounding NPOs are extended to the other people connected to them. This means that the network of NPOs had been diversified via the facilitation of the Ba. This study throws new highlights on the new role for the Ba as a network promoter in addition to the partner as a technology-provider in the NPO ecosystem. Moreover, the network analysis between before-and-after can be used for the evaluation of the effectiveness of the various Ba programs.

In this era of globalization without limitation, many security issues occur, especially in a public network. Internet users significantly increased every single day. However, only some users are aware of security issues when they use Internet services. For the campus network environment, both staffs and students are susceptible to security threats such as data theft, unauthorized access and more due to different levels of awareness towards security threats. This paper is to study the level of awareness among students on security issues based on KSA model. As a case study, the survey was distributed among students in the UTeM campus network. A quantitative study was conducted, and a structured questionnaire has been designed and distributed among students. The variables were focused on three (3) aspects, which are Knowledge, Skill and Ability (KSA). The finding shows the relationship between KSA with the level of awareness among students has been revealed. From the result, Knowledge is the most significant aspect that contributes to high awareness. For the future, a study about increasing students' knowledge about security issues should be addressed.

본 연구는 지식산업화 시대 외국인 지식노동자를 어떻게 재난통신을 통해 보호할 수 있는가를 개념적으로 논의하였다. 외국인 지식노동자들은 높은 교육수준과 경제적지위에도 불구하고 유목적인 특성으로 인한 짧은 거주기간으로 인하여 사회적 자본과 관계의 부족, 그리고 자발적 고립이라는 문제를 가지게 되어 커뮤니티를 기반으로 개발, 운영되는 재난통신 네트워크로부터 소외되기 때문이다. 본 연구는 재난통신 네트워크의 다양한 구조들과 각각의 장단점을 소개하고 전통적인 위계적 계층구조와 무작위 네트워크의 중간인 Small World Network의 구축과 Structural Hole의 활용을 외국인 지식노동자의 소외에 대한 정책 대안으로 제시하였다. 이를 위해 이들 집단과 밀접한 사회적 관계를 유지하는 민간 조직 재난관리 담당자를 통해 이들의 재난 필요를 식별하고 적합한 재난정보와 재난정보를 재난대비 행동으로 전환시키는데 필요한 다양한 추가적인 정보를 제공함으로 재난통신의 효과성을 제고하는 방안을 제시하였다. 이 경우 재난관리기관과 민간 기업이 그들이 이미 구축하여 운영하고 있는 재난통신 구조와 절차를 전면적으로 재구성하지 않고도 외국인 지식노동자를 효과적으로 보호할 수 있게 된다.
