This study examines the relationship between dynamic capabilities and operational capabilities as well as investigates the effect of these capabilities and performance. We also test these relationships on two industry groups categorized into high-tech industries and low-tech industries. We collected 221 firms' data from a questionnaire survey of small and medium-sized enterprises in Korea. Empirical results show that dynamic capabilities and operational capabilities influence performance positively. In high-tech industries dynamic capabilities directly affect performance while marketing capabilities appear to mediate the relationship between dynamic capabilities and performance. Dynamic capabilities show no significant effect on performance for low-tech industries; however, operational capabilities do mediate the relationship between dynamic capabilities and performance.

Purpose - With the increasing uncertainty of China's domestic political and economic environment in recent years, Korean MNC subsidiaries in the Chinese market face greater challenges and competition. Based on the insufficiency of existing research and the need for enterprise management practices, this paper uses the Chinese subsidiaries of Korean MNCs as an example to study and explore how knowledge management and dynamic capabilities affect ambidextrous innovation and the relationship between ambidextrous innovation and subsidiary performance. Design/methodology - From January to March 2019, this study collected 341 valid questionnaires using a survey company specializing in China for the members of the Chinese subsidiaries of Korean MNCs to verify the hypotheses. Using the collected data, the study model was verified using the Smart PLS 3.0 statistical package. Findings - Knowledge transfer and knowledge sharing have positive effects on dynamic capabilities and ambidextrous innovation, and dynamic capabilities have a positive impact on ambidextrous innovation. Ambidextrous innovation has been shown to have a significant effect on subsidiary performance. In addition, a partial mediating effect of dynamic capabilities on the relationship between knowledge management and ambidexterity innovation was found. Originality/value - In the academic context, this paper contributes theoretically to the relationship between knowledge management and ambidextrous innovation, as well as the mechanism of dynamic capability, and to verify the relationship between ambidextrous innovation and corporate performance. Against the background of MNC management, the results of this study provide further enlightenment for managers of subsidiaries.

Service Level Agreement (SLA) is a service providing scheme by a service class agreement between a user and a service provider SLA allows that a user can select an expected service class in various service classes provided from a service provider. Recently, SLA management is adapted to support the end-to-end Qos for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satisfaction for users. In this paper, we propose a dynamic Qos management scheme by IP traffic class controlling based on SLA in B3G networks. Also, to manage dynamic traffic service, we consider Differentiated services (Diffserv) mechanism for the resource management by SLA. An If service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dynamic end-to-end Qos. Hence, in this paper, we consider the buffer threshold scheme for controlling traffic loads and the traffic level control scheme for implementing the dynamic traffic management by the SLA.

The pharmaceutical industry is an industry that provides medicines related to the health and life of the people. The pharmaceutical industry is a traditional regulation industry with the characteristics of R&D(Research and Development), purchasing, manufacturing, distribution and consumption under strict government management. Until now, pharmaceutical companies have continued to make efforts to maintain competitiveness through patent management, new product development, and marketing. However, industries are rapidly changing, including rising costs for developing new products and expanding generic markets. As these changes and uncertainties in the management environment increase, efforts are required to improve the competitiveness of the pharmaceutical industry from a new perspective. In this study, we intend to examine the impact of SCM(Supply Chain Management) dynamic capability of pharmaceutical companies on corporate performance through partnerships to respond to market changes and uncertainties. It was determined that the agility, visibility and flexibility that constitutes the SCM dynamic capabilities would affect the performance of pharmaceutical companies. In this study, the importance of SCM dynamic capabilities and cooperative relationships was identified through surveys by SCM managers of pharmaceutical companies. Consequently, in the pharmaceutical industry, which is a regulatory industry, we have identified that SCM dynamic capabilities and cooperative relationships with partner companies have a significant impact on corporate performance.

During last two decades the transportation system has developed into very intelligent system with GIS, GPS and ITS. The practical transportation management system provides real time response module to manage the customer's order. We have surveyed research papers on the real time vehicle routing problem in last two decades to figure out the dynamic vehicle routing problem. The papers are classified by basic routing algorithms and by managing the dynamic events which are the order management, the routing re-optimization, the routing post-optimization and the waiting strategy.

본 연구에서는 기업 경쟁력의 제고를 통하여 최적화된 경영환경을 조성하고, 기업의 효율성을 높이는데 필요한 혁신 수단인 공급사슬관리를 위한 동적역량의 활용 방향성과 전략을 찾을 수 있는 방안들에 대해 알아보고자 한다. 시장과 기술은 전략적 방향과 문화로 기업이 보유한 정형화된 동적역량에 맞추고, 프로세스에는 공급사슬관리를 위한 동적역량과 관련된 기술을 반영하여 활용할 때에 보다 높은 기업성과를 창출할 수 있을 것이다. 본 연구에서는 시장지향성과 기술지향성이 기업성과에 미치는 영향과 동적역량이 기업성과에 어떠한 영향을 미치는지를 실증적으로 분석하는데 그 목적이 있다. 연구 결과는 시장지향성과 기술지향성은 동적역량에 긍정적 영향을 미치고, 동적역량은 기업성과에 긍정적 영향을 미치는 것으로 나타났다. 즉 동적역량은 시장지향성, 기술지향성과 기업성과 간의 관계를 매개하는 것으로 검증되었으며, 동적역량의 매개효과로 기업의 시장지향성과 기술지향성이 기업성과에 중요한 영향을 미치는 것으로 실증 분석되었다.

Business Rules are formal statements about the data and processes of an enterprise. They present projections of the organization's constraints and ways of working on their supporting information systems. Therefore, their collection, structuring and organization should be central activities within information systems. In an enterprise, business rules are used to represent certain aspects of a business domain (static rules) or business policy (dynamic rules). Hence, regarding problem domains in the organization, business rules are classified into two groups: static and dynamic business rules. The paper introduces a new concept of business rules, Extended Dynamic Business Rule (EDBR) which contains the results of the occurrence of business rule's action. The focus of this paper is in the organizing, defining and modeling of such business rules using Mineau's approach. Mineau's approach is an extension of Sowa's Conceptual Graph theory.

Aiming at the problem of service reliability in resource reservation in cloud computing environments, a model of dynamic cloud resource reservation based on trust is proposed. A domain-specific cloud management architecture is designed in which resources are divided into different management domains according to the types of service for easier management. A dynamic resource reservation mechanism (DRRM) is used to test users' reservation requests and reserve resources for users. According to user preference, several resources are chosen to be candidate resources by fuzzy cluster analysis. The fuzzy evaluation method and a two-way trust evaluation mechanism are adopted to improve the availability and credibility of the model. An analysis and simulation experiments show that this model can increase the flexibility of resource reservation and improve user satisfaction.
