The work in this paper presents development of fuzzy logic-based energy management strategy for a fuel cell hybrid electric vehicle. In order for the fuel cell system to overcome the inherent limitation such as slow response time and low fuel economy especially at the low power region, the battery system has come to compensate for the fuel cell system. This type of hybrid configuration has many advantages, however, the energy management strategy between power sources is essentially required. For the optimal power distribution between the fuel cell system and the battery system, a fuzzy logic-based energy management strategy is proposed. In order to show the validity and the robustness of suggested strategy, some simulations are performed for the standard drive cycles.

The purpose of this study is to explore financial investment knowledge related to multi-strategy, which is not generally shared. Through case studies, we will share it with the domestic hedge fund market. Since the era of full-fledged private equity hedge funds in Korea opens, many funds are created; however, reality is that there is a lack of diversity in strategies. Initially, it started with a simple stock long/short strategy, and various strategies such as mezzanine and alternative investments are in use but funds using multi-strategy are limited. This study aims to present an empirical application plan for hedge fund management strategies using a case study. It will specifically focus on process of achieving Absolute Return using the Multi Strategy technique actively used in securities firms' Prop Trading. With the results of this study, we intend to contribute to those fund managers and desired researchers who are utilizing multiple strategies in the hedge fund management to pursue Absolute Return and to help them strengthening their financial knowledge and competitiveness.

This study empirically investigated the effects of knowledge management(KM) strategic alignment on the KM activities as well as the product and process innovation of manufacturing firms. Based on the framework, which employs the usage levels of target costing systems(TCS) and information technology(IT) infrastructure, four types of KM strategies were identified and proposed：mixed, explorative, exploitative and negative strategies. In this research, these four types of KM strategies were empirically validated. According to the results of this study, it was found that when a explorative KM strategy is aligned with a low-cost strategy, KM activities are activated and the degree of a process innovation is increased. It was observed that in the case of the alignment between a differentiation strategy and a exploitative KM strategy, both KM activities and the level of a product innovation are enhanced. The results also demonstrated that for the enhancement of both a process and a product innovation through the activation of KM activities, a mixed KM strategy must be aligned with a composite business strategy, which focuses on a low-cost as well as a differentiation strategies. Accordingly, it is concluded that the KM activities and the levels of the product and process innovation can be activated or improved with the alignment of the KM strategies and business strategies.

This study examines the relationship between multiple sales force management practices and performance within each of Miles & Snow (1978)'s strategy types and Walker & Ruekert (1987)'s strategy types. The findings are as follows : First, Prospectors seem to be associated with increased performance when they are utilizing a relationship selling strategy, internal sales force, moderate levels of supervision, outcome-based control system and incentive-oriented compensation system. Second, Analyzers seem to be associated with increased performance when they are utilizing a relationship selling strategy, internal sales force, outcome-based control system to deal with the instability in their strategic focus. Third, Low Cost Defender seem to be associated with increased performance when they are utilizing a relationship selling strategy, external sales force, low levels of supervision, outcome-based control system and salary-oriented compensation system. Fourth, Differentiated Defenders seem to be associated with increased performance when they are utilizing a relationship selling strategy, high levels of supervision, balanced (outcome+behavior) control system and salary-oriented compensation system.

Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

This paper describes the Blue Ocean Strategy and Business TRIZ (Russian Theory of Inventive Problem Solving) Tactics as one method for knowledge creation and innovation. The opening new market avoiding keen competition is very popular recently and is not just prosper, but survival problem. As one new strategy for finding new market, the Blue Ocean Strategy gives the big blueprint for new market, but has no enough tools to make more concrete ideas. In this paper, we suggest using the Strategy Campus and other tools in the Blue Ocean Strategy at initial stage and then, compensating the TRIZ principles to make more concrete ideas for new market as tactics. We applied it to find the new market for conventional newspaper industry and EBS (Education Broadcast System) management innovation in Korea as case studies and got better results comparing to using only the Blue Ocean Strategy.

The overall objective of this article is to identify the strategic type of Korean hospitals in terms of Porter's framework and to examine differences in performance of the hospitals across strategic types. A survey was conducted through structured questionnaire for 739 hospitals in Korea and the data from 120 hospitals were utilized in the final analysis. Study results indicate that the most frequently used strategy was 'stuck-in-the-middle strategy'(26.7%), followed by 'focused cost leadership strategy'(24.0%), 'focused differentiation strategy'(20.8%), 'cost leadership strategy'(15.8%), and 'differentiation strategy'(13.7%). Overall, 'focused differentiation strategy' showed superior performance in terms of profitability of services, ability to retain patients and growth in revenue, while 'differentiation strategy' produced relatively low performance in general. Implications of these findings are also discussed.

The purpose of this study is to provide a rational management strategy to improve the management performance of companies through intellectual property activities. Through this study, we aim to explore countermeasures to strengthen competitiveness in a changing global environment. A survey of 200 companies was conducted from September 1 to October 30, 2023. Statistical analysis was conducted using frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and difference analysis. The conclusions are as follows. First, the impact of intellectual property activities on management performance was found to be creation and utilization. Second, the impact of management strategies on management performance was found to be differentiation strategy, cost advantage strategy, and concentration strategy. Third, cost advantage strategy has a partial mediation effect on the relationship between creation activities and managerial performance of intellectual property activities. Fourth, the differentiation strategy has a partial mediating effect on the relationship between the creation of intellectual property activities and managerial performance. In addition, differentiation strategy has a full mediating effect on the relationship between the utilization of intellectual property activities and performance. Fifth, concentration strategy has a partial mediating effect on the relationship between intellectual property activity utilization and management performance. Sixth, there is a difference between creation activities, protection activities, utilization activities, cost advantage strategy, differentiation strategy, financial performance, and non-financial performance based on venture certification status. As the importance of intellectual property is increasing in the era of technological hegemony, IoT companies will need to improve their management performance through venture certification and strategies utilizing intellectual property in order to secure future competitiveness. Based on this study, we hope that IoT companies will maximize their performance by implementing efficient strategies that consider IP activities.
