In recent years, the Indian market has gained worldwide attention in the global trading business environment. Korean companies are also seeking to enter the indian market, and their foreign trade investment strategy is based on the Global Value Chain(GVC). In this study, we examine difference from traditional investment strategy to GVC investment strategy in the age of 4IR(fourth industrial revolution) through using POLS model(pooled least square), FEM(fixed effect model), and REM(randomized effect model). Based on the analysis of 84 monthly data related to the FDI and international trade effects between Korea and India, the following results were found. As Korean companies increased their share of export to the Indian market and export to the Indian market, the number of new companies directly invested in overseas market increased. However, the amount of import into the Indian market was relatively low in relation to the number of new companies directly in overseas markets. As a result of analyzing the investment strategy of the GVC in India, the GVC has shifted from manufacturing to process upgrading to enter the GVC on Smile Curve.

There is no clear standard for estimating the power distribution of fuel cells and batteries to meet the required power in hydrogen electric vehicles. In this study, a hydrogen electric vehicle simulation model equipped with a vehicle electric component model including a fuel cell system was built, and a power distribution strategy between fuel cells and batteries was established. The power distribution model was operated through two control strategies using step control and fuzzy control, and each control strategy was evaluated through data derived from the simulation. As a result of evaluation through the behavior data of state of charge, fuel cell current and balance of plant, fuzzy control was evaluated as a proper strategy in terms of control stability and durability.

This study attempts to discover a differentiated service strategy for the hotpot restaurant industry from the perspective of Chinese Generation Z customers, as well as to further explore the inner needs of Chinese Generation Z to make practical implications for discovering the method of gaining their satisfaction and loyalty. This paper employs questionnaires to collect analytical data and through a case study to produce company strategies. Smith's Marketing Ethics Sequential System Model (SMESSM) is introduced in this paper for the decision of whether the case study company Haidilao Hot Pot should make a new strategy on service based on Generation Z's consuming behavior. The findings of this study demonstrate that hotpot restaurant must differentiate their services for Generation Z from older generation customers to gain a sustainable development of the hotpot business. Proper differentiated service will not only improve Generation Z's dining experience but also reduce costs. This paper is the first to discuss differentiated service strategy in the hotpot restaurant business from the perspective of Generation Z customers. And a Chinese experience of SMESSM for practical use is introduced in this paper, which enriches the relevant implications for future research on business strategy.

In Korea, a master plan for records management standardization has been established and implemented by National Archives of Korea in a short manner comparing with other countries which pursued the standardization gradually in a long-range policy. But many standards developed under the plan has being criticized in terms of standards quality and their effectiveness by records managers in public sectors. According to the needs of systematic standardization strategy development to overcome the problems, it proposes a model for developing standardization strategy for records management, which is considering strategic goles, principles and 4 strategy areas to be reformulated. This model suggests the directions to select appropriate targets and priorities to be standardized, and to improve standardization procedure and policy framework as standardizing strategy's key points.

Purpose: This study aimed to develop a strategic business conceptual model for large state plantations in West Java Province and Banten Province, Indonesia. The model was built through causal relationships and interrelationships between marketing strategies and business strategies that affect business performance on large state plantations. The plantation sector provides the largest contribution to gross domestic product and is an important part of national food distribution efforts. Research design, data, and methodology: This study used a literature review adapted from Pret and Logan (2019), which followed the guidelines of Tranfield et al. (2003), derived from the Scopus website with Q1/Q2 quartiles and inclusion/exclusion criteria published from 2012 to 2021. Results: Based on a systematic literature review approach, we constructed the strategic business conceptual model for large state plantations based on a combination of four causal and interrelationship variables that affect business performance, namely, industry attractiveness, unique capabilities, innovation management, and collaboration strategy. Conclusions: This research explains the relationship between industry attractiveness variables and unique capability as independent variables that can affect business performance through collaboration strategy and innovation management as intervening variables in the plantation sector, especially large state plantations, which have not been found in previous studies.

This study established a marketing strategy for the KAI Light Civil Helicopter (LCH) market by applying a Brand Asset Valuator (BAV) model to the LCH project currently underway by Korea Aerospace industries (KAI). Through literature reviews, the global scale of LCH projects and the development status of KAI LCH were identified. Subsequently, four sub-items from the BAV model were applied, and an expert survey was conducted. The primary data underwent an analysis process following the completion of the validity and reliability verification stage. The analysis revealed that the highest value was in the knowledge indicator, while the lowest value was in differentiation. The analysis confirmed KAI LCH's position on the BAV Power gird, indication that brand vitality, particularly differentiation, was lower than brand knowledge. Accordingly, this study finally presents a new marketing strategy to enhance the brand vitality of KAI LCH.

This research aims to develope a maturity evaluation model on the technology management competence (MEMTMC) and to investigate the relationship between technology management competencies and maturity evaluation level in Korean firms. After research framework building through literature review and field study focusing on interview process, a maturity evaluation model was suggested, including technology management competency factors such as vision and strategy, leadership, resources, projects, performance management, and systematic procedures. Through the empirical study on the 111 Korean firms, the MEMTMC model was tested and some hypotheses were examined. As a result of the research, we found that the MEMTMC is significant statistically to evaluate the technology management competencies of firms from a practical point of view. Additionally, these findings suggest that firms can build up their technology management competencies, including the vision and strategy, leadership, resources, projects, performance management, and systematic procedures in order to raise their maturity level of technology management competencies. But this research has some limitations such as this MEMTMC has not considered separately the variety of industry, not enough survey respondents and 5 level group firms etc.

This study presents a model-based gain scheduling strategy for PI-based EGR controllers. The air-to-fuel ratio is used as an indirect measurement of the EGR rate. In order to cope with the nonlinearity and parameter varying characteristics of the EGR system, we proposed a static gain model of the EGR system using a new scheduling parameter. With the 810 steady-state measurements, the static gain model achieved 0.94 of R-squared value. Based on the static gain of the EGR system, the PI gains were robustly designed using quantitative feedback theory. Consequently, the gains of the PI controller are scheduled according to the static gain parameter of the EGR path in runtime. The proposed model-based gain scheduling strategy was validated through various operating conditions of engine experiments such as setpoint step responses and disturbance rejections.

Real-time hybrid simulation (RTHS), which has the advantages of a substructure pseudo-dynamic test, is widely used to investigate the rate-dependent mechanical response of structures under earthquake excitation. However, time delay in RTHS can cause inaccurate results and experimental instabilities. Thus, this study proposes a model-based adaptive control strategy using a Kalman filter (KF) to minimize the time delay and improve RTHS stability and accuracy. In this method, the adaptive control strategy consists of three parts-a feedforward controller based on the discrete inverse model of a servohydraulic actuator and physical specimen, a parameter estimator using the KF, and a feedback controller. The KF with the feedforward controller can significantly reduce the variable time delay due to its fast convergence and high sensitivity to the error between the desired displacement and the measured one. The feedback control can remedy the residual time delay and minimize the method's dependence on the inverse model, thereby improving the robustness of the proposed control method. The tracking performance and parametric studies are conducted using the benchmark problem in RTHS. The results reveal that better tracking performance can be obtained, and the KF's initial settings have limited influence on the proposed strategy. Virtual RTHSs are conducted with linear and nonlinear physical substructures, respectively, and the results indicate brilliant tracking performance and superb robustness of the proposed method.
