The 5G Core Network (5GC) is an essential part of the mobile communication network, but its security protection strategy based on the boundary construction is difficult to ensure the security inside the network. For example, the Network Function (NF) mutual authentication mechanism that relies on the transport layer security mechanism and OAuth2.0's Client Credentials cannot identify the hijacked NF. To address this problem, this paper proposes a trust model for 5GC based on NF interaction behavior to identify malicious NFs and improve the inherent security of 5GC. First, based on the interaction behavior and context awareness of NF, the trust between NFs is quantified through the frequency ratio of interaction behavior and the success rate of interaction behavior. Second, introduce trust transmit to make NF comprehensively refer to the trust evaluation results of other NFs. Last, classify the possible malicious behavior of NF and define the corresponding punishment mechanism. The experimental results show that the trust value of NFs converges to stable values, and the proposed trust model can effectively evaluate the trustworthiness of NFs and quickly and accurately identify different types of malicious NFs.

Purpose This study empirically investigates the impact of information technology(IT) investments on the financial and non-financial performance of a manufacturing firm. We examined the interaction effects of IT investments and strategic applications levels of information systems(IS). This study also demonstrated the three-way interaction effects of IT investments, levels of IS strategic applications, and perceived environmental uncertainty(PEU). Design/methodology/approach For this study, empirical data were collected from 98 manufacturing firms with the structured questionnaires. The data were analyzed with multiple regression models, and partial derivatives were utilized to identify the directions of the impact. Findings From the empirical results, it was found that when both the levels of IS strategic applications and the degrees of IT investments are high, the ratios of the costs of goods sold to total sales(RCGS) and the labor costs to total sales(RLCS) are decreased, as it were, the performance of a firm is improved. However, it was observed that when the levels of strategic IS are low, the high degrees of IT investments do not contribute to the improvement of a performance. The results showed that when the levels of strategic IS are high, the high degrees of IT investments incur the high RSAE not low RSAE. When PEU is considered, the empirical results showed that under the low degrees of PEU, the IT investments under high levels of strategic IS applications (strategic IT investments) improve the performance, as it were, low RCGS, and high degrees of perceived financial and non-financial performance. However, under high PEU, it was observed that high degrees of strategic IT investments do not increase the performance. When PEU is high, the strategic IT investments reduce RSAE, and under low PEU, RSAE is increased.

Innovation with strategic interaction is to overcome the technological uncertainty and to create co-evolution through competition among individuals or organizations for the acceleration of innovation. The concept of innovation in the past was concentrated on cooperation rather than on competition for the efficient management of limited resources. However, in order to minimize the technological uncertainty, we need an innovation on the basis of competition between organizations. Competition stimulates technological adaptability. It is on the analogy of complex system. This is to satisfy consumers' needs, to transform the resources into a technology, and to apply for the development of new products and new technologies. If the emergence of a new technology threatens present technology and develops into a new level of technology through inter-relation, it becomes a mutually supporting technologies. When theses effects are simultaneously realized, it is possible for firm to have strategical innovation and to create a mutually evolutionary development. Furthermore, when the competition among more than two individuals or two organizations continues towards the same direction, the mutual competition and cooperation can be expected to create a synergy effect. The competitive environment should be composed of R&D, production, and consumers' choice. This will lead to interaction among organizations through strategic competition and cooperation. Intra-firm competition and Inter-firm competition are required to exist together.

기업의 내적 R&D 열의를 키우기 위해 외부 파트너와의 제휴가 가치 있다는 연구가 많이 진행돼 왔다. 하지만 혁신적 성과를 창출하기 위해 전략적 제휴가 가진 잠재적 역할을 활용하는 방법에 대해서는 잘 알려져 있지 않다. 본 연구는 전략적 제휴의 가치를 연구하고, 전략적 제휴의 혁신 성과에 대한 영향에 인적 자본이 어떤 역할을 하는 지를 분석한다. 본 연구는 인적 자본의 흡수역량이 전략적 제휴와의 상호작용을 통해 기업의 혁신에 끼치는 영향에 초점을 맞춘다. 2,205개의 대한민국 벤처기업을 대상으로 한 분석에서 전략적 제휴는 혁신 성과에 정의 유의한 영향을 미치는 것으로 나타났다. 하지만 전략적 제휴와 혁신 성과 간의 관계에서 인적 자본의 조절 역할은 부의 유의한 영향을 보여준다. 이것은 외부의 파트너로부터 얻은 지식과 정보를 내재화시키는 능력이 중요함을 보여준다. 본 연구는 인적자본의 상호작용을 고려함으로써 전략적 제휴의 효과성을 증진시키고자 하는 경영자에게 가치 있는 시사점을 제공한다.

이 연구는 자유주제 과학탐구 과정에서 일어나는 인지수준 향상 정도 및 탐구단계별 상호작용을 분석함으로써, 자유주제 과학탐구에 대한 질적 이해를 돕고자 하였다. 자유주제 과학탐구는 인지수준이 과도기(2B/3A)이고, 학습동기수준이 심층학습형, 심층능력형인 학생들의 탐구능력 신장에 긍정적인 효과가 있었다. 또한 학생들은 탐구과정 중 주제 및 가설설정단계에서 어려움을 겪으며, 자유탐구가 진행됨에 따라 논의의 기술은 증가하나, 상호작용의 질적 향상은 쉽게 나타나지 않음을 알 수 있었다. 심층학습형은 모둠 내에서 사고의 정교화를 촉진하는 역할을 하고 있었다. 심층능력형은 가장 주도적으로 상호작용에 참여하여 논의를 이끄나, 탐구결과에 대한 집착으로 과정적 측면을 소홀히 하는 경향이 있었다. 그리고 피상능력형은 하위수준의 상호작용이 많아서 논의를 심화시키지 못하나, 자유탐구가 진행됨에 따라 점차 상위수준의 상호작용이 증가하는 긍정적인 변화를 보였다. 이 연구로부터 자유주제 과학탐구 활동의 특성 및 자유주제 과학탐구 활동의 진행과 모둠구성에 대한 시사점을 얻을 수 있었으며, 이에 대해 논하였다.

This Research aims to analyze the effects of SCM management capabilities and IT capabilities on firm performance. The strategic performance was shown to be positively and significantly affected by flexibility and responsiveness which were proxies for SCM management capabilities. However, neither main effect of IT capability nor interaction effects of IT capability and SCM management capability on firm performance was found.

Purpose: Previous research has found that organizational performance pressures and barriers have an effect on the long-term viability of Micro, Small, and Medium Enterprises (MSMEs). Furthermore, MSMEs' intellectual capital and strategic orientation, according to recent research findings, have an impact on this. The goal of this study is to see how intellectual capital and strategic orientation affect MSMEs' performance. Research design, data and methodology: The performance of MSMEs is the dependent variable, with intellectual capital, market orientation, learning orientation, and technical orientation as independent factors. With a sample size of 113 respondents, this research focused on information technology-based MSMEs in Indonesia's Solo Raya area. Data was analyzed use Confirmatory Factor Analysis for the reliability test and path analysis SEM. Results: The interaction between intellectual capital and strategic orientation in respect to MSMEs' performance reveals that innovation capability serves as a partial mediator in the relationship between intellectual capital and technical orientation and organization performance. Conclusions: In general, intellectual capital and strategic orientation have a positive substantial influence on innovation, according to the findings. Furthermore, they have a considerable favorable influence on the performance of MSMEs. It's just that intellectual capital has no discernible impact on knowledge sharing.

Purpose - The purpose of this study was to examine the effects of corporate strategic deviance on firm value considering a firm's cost stickiness. Design/methodology/approach - This study used 40,823 firm-year observations from the Korean stock markets, KOSPI and KOSDAQ. Several multiple regression models were used in order to analyze the data Findings - First, unlike the previous results, corporate strategic deviation is positively associated with firm value. Second, the cost stickiness of a firm is positively related to firm value. Third, the interaction effect between strategic deviation and cost stickiness has negative relation with firm value. Fourth, An increase in standard deviation directly correlates with a decrease in firm value for firms with high levels of controlling shareholder ownership or that are part of chaebols. Research implications or Originality - Strategically deviant firms can experience an increase in firm value due to their future competitive advantage. Moreover, stickiness of costs generally has a positive impact on firm value. However, when firms with high levels of cost stickiness employ strategic deviant strategies, there is a risk of agency problems such as excessive overinvestment, which can negatively impact firm value.
