Within the article, strategic guidelines for the modernization of microeconomic systems are identified. Modernization levels of the potential implementation are formalized for enterprises: contractile, extensive technical, technological, progressive, adaptive, steady, intensive, creative, absolute and leader modernization. This allowed to specify the directions and tasks of the enterprise modernization at different management levels. Accordingly, the conditions and criteria for selecting resource tools are set. It is proved that the strategies of the potential modernization of enterprises must be carried out at four main management levels: first, at the enterprise level; secondly, for a particular type of product / service; third, by functional directions of modernization of separate spheres of the enterprise activity or responsibility, fourth, at the level of structural units of the enterprise. It is substantiated that in the processes due to the activation of the potential modernization, the resources are transformed into the results of the innovation implementation and the investment strategies modernization. A system of tasks for the corporate strategies implementation in order to modernize microeconomic systems has been formed. Key vectors of the activation determine the nature and properties of investment resources and necessary innovations to enhance the modernization potential. Therefore, the system of innovation and investment strategies' modernization, based on the vector and resource provision of the modernization process, is specified:

국내 정치적 사회적 경제적 요인 및 국제 정치 상황, 해외 경제 동향 등의 요인들을 비롯한 IMF이후의 금융시장 개방에 따른 외국투자자본의 유출입으로 인하여 한국 금융시장의 불확실성은 더욱 증가되었다. 특히 투자자들은 의사결정에 더 많은 혼돈을 겪게 되었고 투자 시 도움을 줄 수 있는 보다 유용한 도구들을 필요로 하게 되었다. 본 연구는 시스템 트레이딩을 이용하여 선물시장에서 거래 할 때 최적의 매매 타이밍을 알아보고 이에 적합한 전략을 알아보는 것이 목적이다. 패턴인식 알고리즘인 동적 시간 와핑 (DTW; Dynamic Time Warping) 알고리즘을 이용하여 빈도별 (10분, 30분, 60분, 일 별) 유사 패턴을 찾아내고 최적의 매매 타이밍을 분석한다. 이를 위해 주식시장의 대표적인 패턴들을 알아보고, 유사한 패턴을 보이는 기간을 DTW를 이용하여 빈도별로 분석한다. 유사한 패턴들의 검증을 위해 기술적 지표들의 개별 전략을 적용한 거래 시뮬레이션을 실시한다. 시뮬레이션 결과 대부분 30분 데이터에 적용된 전략들이 높은 수익률을 가져왔다.

Due to the development of information technology of digital revolution, It is recognized that technical development and standardization are getting important. In this study we executed questionnaires for experts in industry, academy and research institution to survey on the demand for the mobile internet technical development and standardization in the IMT2000 environment. This analysis of the technical development and standardization can be utilized to make strategies of related industry and alternatives of policy for our government. It is expected that this study will contribute to the preoccupy of global market.

The development of very high speed train system is a complex series of interrelated tasks, many of which have some degree of uncertainty associated with the successful outcome. Successful projects recognize and provide for the major uncertainties and technical unknowns with specific development strategies. The development strategies described in this paper incorporated the experiences of the advanced countries in high speed train technologies, the current technical status of Korean industries and the operating requirements of Korean High Speed Railway.

In this research, the world top steel companies' technical changes were measured by the nonparametric Malmquist index. Steel industry's production frontier which was composed of multiple inputs and multiple outputs was defined by using real data of the companies from 1986 to 1998, and then the variability of technical progress(or regress) was analyzed during that period. The dynamics of individual steel companies\` technical changes, periodical technical changes, and each country's technical chanties were explained. A matrix which was based on technical chanties, technical efficiency changes, and scale efficiency changes was designed to assist to find out current position and In build up future strategies. This research results will be an valuable input to the early stage of formulating competitive strategy because the technical core capability is an important source of the each companies's competitiveness.

In this research, optimum design of the combined solar collector, geothermal heat pump and thermal seasonal storage system for heating and cooling a sample greenhouse is studied. In order to optimize the system from technical point of view some new control strategies and functions resulting from important TRNSYS output diagrams are presented. Temperatures of ground, rock bed storage, outlet ground heat exchanger fluid and entering fluid to the evaporator specify our strategies. Optimal heat storage is done with maximum efficiency and minimum loss. Mean seasonal heating and cooling COPs of 4.92 and 7.14 are achieved in series mode as there is no need to start the heat pump sometimes. Furthermore, optimal parallel operation of the storage and the heat pump is studied by applying the same control strategies. Although the aforementioned system has higher mean seasonal heating and cooling COPs (4.96 and 7.18 respectively) and lower initial cost, it requires higher amounts of auxiliary energy either. Soil temperature around ground heat exchanger will also increase up to $1.5^{\circ}C$ after 2 years of operation as a result of seasonal storage. At the end, the optimum combined system is chosen by trade-off between technical and economic issues.

Seismic upgrading of existing structures is a technical and social issue aimed at risk reduction. Sustainable design is one of the most important challenges in any structural project. Nowadays, many retrofit strategies are feasible and several traditional and innovative options are available to engineers. Basically, the design strategy can lead to increase structural ductility, strength, or both of them, but also stiffness regulation and supplemental damping are possible strategies to reduce seismic vulnerability. Each design solution has different technical and economical performances. In this paper, four different design solutions are presented for the retrofit of an existing RC frame with poor concrete quality and inadequate reinforcement detailing. The considered solutions are based on FRP wrapping of the existing structural elements or alternatively on new RC shear walls introduction. This paper shows the comparison among the considered design strategies in order to select the suitable solution, which reaches the compromise between the obtained safety level and costs during the life-cycle of the building. Each solution is worked out by considering three different levels of seismic demand. The structural capacity of the considered retrofit solutions is assessed with nonlinear static analysis and the seismic performance is evaluated with the capacity spectrum method.
