With the saturation of the local market, the domestic media industry is searching for new growth drivers by crossing over to other industries, but due to the limited size of the market, results fail to meet expectations. Despite its strengths in cultural contents, as verified by the Korean Wave Hallyu, and advanced platform services, the industry feels threatened by the entry of global foreign media businesses in the domestic arena. This and the stagnated growth in the local media market are challenges we are facing today. On the other hand, it could prove to be a timely opportunity to transform the existing media industry structure where exporting hardware and terminals is at the heart of a globalized business into a structure based on software and contents exports. Based on such critical thinking, this study examines the current status of media markets, home and abroad, and aims to come up with strategic measures through a discussion on the issues and methods proposed for the globalization of local media businesses from a holistic viewpoint based on ecosystem, M&A and contents.

Industry Foundation Classes(IFC)는 Building Information Modeling(BIM)을 위한 표준 데이터 스키마로 정보의 상호운용성 확보를 위한 핵심이지만, 건물만을 대상으로 하고 있어 토목 시설물에 적용하기에는 한계가 있다. 이에 따라 기존 IFC에 토목 시설물을 위한 새로운 요소를 추가하는 연구가 진행되었지만, 상용 소프트웨어가 해당 기능을 추가하기 전에는 새로운 스키마를 활용할 수 없다. 본 연구에서는 토목 시설물에 적용하기 위한 IFC 데이터 스키마 활용 방안을 제시하고, 토목시설물을 위한 확장 요소와 기존 IFC 요소와의 정보 매핑을 통한 확장 IFC기반의 토목 시설물 정보모델링 방법을 제시하였다. 그리고 철도의 궤도 및 침목에 대한 IFC 확장 스키마를 제시하고 제시한 방법을 적용하여 그 활용성을 검증하였다.

과거 소프트웨어 품질은 곧 제품품질이란 인식이 지배적이었다. 하지만 현대에 소프트웨어가 거대화되고 복잡해짐에 따라 제품품질만을 가지고서는 고객의 요구조건에 맞는 양질의 소프트웨어를 제작하는데 있어 한계가 있었다. 이러한 이유로 현재 국내외 많은 기업들은 프로세스 개선을 통한 제품품질 향상을 위하여 노력을 기울이고 있다. 프로세스 개선활동 중 측정 활동은 프로세스 개선에 대한 효과를 향상시키며, 프로세스 개선 활동을 파악하고, 이를 효과적으로 구현하는데 있어 많은 도움을 줄 수 있다. 본 논문은 현재 국내외 많은 기업들이 프로세스 개선 모델로 채택하고 있는 CMMI를 기반으로 측정 프로그램에 관한 연구를 수행하였다. CMMI의 프로세스 영역 중 측정 프로세스 수립에 대해서 다루고 있는 MA 프로세스 영역을 기반으로 측정 프로그램을 수립하였으며, 이렇게 개발한 측정 프로그램을 통해 CMMI 각 레벨 별로 측정 프로그램이 어떠한 차이를 두고 있으며, 어떻게 측정 프로그램을 작용할 지에 대해 연구하였다. 본 연구를 통해 CMMI 기반의 프로세스 개선을 수행하고 있거나 시작하려는 기업들에게 측정 프로그램 수립 지원할 수 있으며, 더 나아가 레벨 별로 진화하는 측정 프로그램의 로드맵을 제시하고자 한다.

Many countries have been developing BIM-based building code checking system and studies in the utilization of Industry Foundation Classes (IFC) in building code checking. IFC is the open standard of BIM format. Currently, there is a disadvantage that could not include all of the attribute for the regulations of each country and there is the problem with the interoperability of the different defined IFC approach between BIM software. This study focus on developing, derived object and property by comparing through domestic regulation and IFC2x3 specification provided by the buildingSMART and classified review type depending on the interoperability of derived information. According to classified review type, the IFC data structure was established and property mapping contents were developed by including BIM software compatible information and creating a type of review plan. When the developed property mapping contents are applied into BIM-based building code checking system, checking of the BIM data generated from various fields is made effective and thus improving the interoperability of information.

개인형 컴퓨터 시대의 도래로 컴퓨터 산업은 새로운 전환기를 맞이하였다. 기존의 산업구조는 메인프레임 컴퓨터 시대인 수직적으로 통합된 기업들에 의해 확실히 구분할 수 있는 경계가 존재하였고 기업 독자적으로 완전한 시스템을 생산하였으며 하드웨어, 운영체제 및 운영체제 프로그램에 대한 독자적인 설계에 근거하여 산업내 이 세가지 분야에 대해서 경쟁하였다. 따라서 시장의 경계가 뚜렷한 독점적인 산업구조를 유지함에 따라 경쟁보다는 정적인 시장 점유와 호환성보다는 독자적인 시장 개척에만 초점을 맞추었다. 그러나 개인형 컴퓨터시대의 도래로 부품의 표준화와 개방체제로 산업이 형성됨에 따라 공급자간 가격경쟁이 심화되고 자유 경쟁체제를 전환되면서 새로운 산업구조의 변환기를 맞이하여 소 산업별 수평적 분화현상이 발생하고 있다. 본 논문에서는 이러한 현상을 분석하고 수평구조하에서의 바람직한 산업 구조의 모형을 제시하고자 한다.

Vinalines is actually known as not only one of Vietnam's state-sponsored economic giants but also the largest shipowner by tonnage in Vietnamese shipping industry. Therefore, a question of how to improve business performance of the corporation is always received deep attention by Vietnamese government, specially after the seriously economic scandal of Vinalines in a last few years. Among development strategies, the study focuses on short-term one in which Vinalines is recommended to restructure its own fleet in order to optimize performance of fleet operation and minimize costs while meeting the customer's shipping demand in near future. The first section is of introduction. Via method of statistical data analysis, section 2 brings to readers a panorama about the development profile and the current situation of development of Vinalines. In section 3, the authors use linear programming for setting a cost-minimization model optimizing Vinalines fleet structure based on available statistics and forecast information by Vinalines. The optimization problem is solved by applying AIMMS software in section 4. Finally, some conclusions and proposals by authors for the development of Vinalines are given.

The purpose of this study is to develop a force-platform system suitable for real situations in industry. The developed system is a 3-axis measurement type. It consists of force-transmission, force measuring circuit, and the software that analyzes the measured force. The force-transmission transmits forces to 3 axes, which has a physical structure to minimize the interference among those axes. Force measuring circuit consists of DSP (digital signal processor) for flexible disposal of change of measurement algorithm, elimination of noise and maintenance of precision. The functions of the software are the calibration which revises the measurement error occuring during data acquisition, and various analyses of forces. The result of the experiment shows that the developed system has about 1% measurement error, is stable for repeated experiments, and is not effected by temperature change.

In the recent day, fatigue life prediction techniques play a major role in the design of components in th ground vehicle industry. Full scale durability testing in the laboratory is an essential of any fatigue life evaluation of components or structure of the automotive vehicle. Component testing is particularly important in today's highly competitive industries where the design to reduce weight and production costs must be balanced with the necessity to avoid expensive service failure. Generally, multi-axis durability testing simulator is used to car교 out the fatigue test. In this paper, the operation software for simultaneously driving 3-axis simulator is developed and the real-time signals of input-output data are displayed in window of PC. Moreover, the displacements and the loads of 3-axis actuators are calibrated separately and the operating characteristics of the actuators are evaluated.

The automotive industry faces many competitive challenges including weight and cost reduction to meet need for higher fuel economy. It is a trend that a lot of parts have been currently changed to an aluminum alloy from steel materials. It is required more precise analysis for practical load because of complexities and varieties of vehicle structure. In this study, the shape optimization using a FEA is performed to determine the design of the knuckle. The size optimization is carried out to find thickness while the stiffness constraints are satisfied. A commercial optimization software MSC/NASTRAN is utilized for the structural analysis and the optimization processes.
