국내 소프트웨어산업의 진흥을 위하여 공공 System Integration(이하 SI) 시장에 대기업 참여를 전면적으로 제한하는 소프트웨어산업진흥법 개정안이 발효됨에 따라 공공 SI 시장이 중소기업위주로 개편되어야 할 상황에 놓여 있다. 그러나 공공 SI 시장은 중소기업이 감당하기에 무리가 따르는 대형 SI 프로젝트가 다수여서, 대형 SI 프로젝트를 발주해야 만하는 발주기관은 당혹해 하고 있고, 어느 중소기업도 자신의 한계를 넘는 대형 프로젝트 수주를 위해 적극적으로 뛰어들지 못하고 있다. 본 논문은 중소기업위주의 SI 시장 활성화를 위하여 취해야 할 접근 방법을 제안한다.

온톨로지의 재사용을 위해 온톨로지를 통합하는 방법에 대한 연구가 진행되친 있다. 그리고 다양한 온톨로지 통합 도구들이 개발되어 사용되고 있다. 그러나 기존의 온톨로지 통한 방법 및 도구는 셋 이상의 온톨로지를 한번에 통합할 수 없으며, 파수의 작업자가 동시에 통합 작업을 할 수 없는 단점이 있다. 본 논문에서는 메타온톨로지를 이용한 온톨로지 통합 프로세스(OntoIntegProcess)를 제안하고, 온톨로지 통합 프로세스에 기반하여 온톨로지 통합 시스템(OntoIS)을 개발한다. 온톨로지의 통합 실험을 통해 제안한 프로세스와 시스템의 효용성을 확인한다.

After the COVID-19 pandemic, a global economic downturn and a recession in the shipping market are expected, it is important for domestic shipping companies to establish appropriate strategy in response to the recession. Accordingly, domestic shipping companies should grow into integrated logistics companies that combine shipping and logistics in the future. And for this purpose, it is necessary to actively promote logistics integration with external shipping and logistics companies. This paper presents the direction of logistics integration for domestic shipping companies to develop as integrated logistics operators with competitiveness in the global shipping market, and presents detailed alternatives. Domestic shipping companies lack the infrastructure such as ships, port terminals, and warehouses, so they have a weak capacity to independently promote logistics integration. At the shipping company level, a logistics integration promotion strategy should be established, and accordingly, logistics infrastructure, service network, and logistics integration operating system should be established. The government should provide tax benefits for logistics integration, financial support for M&As led by domestic shipping companies, a standardized information sharing system, and preparation of educational courses for nurturing digital manpower.

Since Industrial Revolution, the sudden industrialization and population explosion have brought about a serious environmental pollution on the air of the earth, the quality of water and the soil, and the greenhouse effect by the destruction of the ozone layer and the greenhouse gas, the organism diversity decline, the desertification by the ruining of woods and the overall global environmental pollution such as the contamination of the ocean and rivers have been come to the front. So the new recognition on the environment is being spreaded in construction business and the efforts for certification acquisition of ISO 14000 being followed by ISO 9000 are progressing, Accordingly, with an example of H Company where integration system is built so that it can minimize the efforts and cost at the construction of the management system, operation and management after the fact, this paper shall suggest the practical scheme of 3 steps through a study to integrate both existing quality management system and new environmental management system. As the integration system of the quality and environment which is constructed by this method is executed, the number of the established and managed document is cut by about a third and so the disorder to encounter between these documents is prevented and unnecessary efforts is reduced in constructing a system, consequently the efficiency of the system is accomplished. Also as the dualization of quality management system and environmental management system additionally needs more men and money after certification acquisition, the non-construction of the integration system may give rise to a cause to aggravate the burden of the company and hereafter when a new system is imported, it may be very difficult to integrate the system. This system integration enables a efficient and effective system to be constructed , operated , and managed after the fact.

본 논문은 독일통일 후 구동독지역에서 실시된 학제통합 과정에 대한 고찰을 통해 남북한 통일 후 교육통합 과정에서 고려해야 할 시사점을 도출하는데 연구의 목적이 있다. 독일 통일 전후 단계에서 구동독의 학제는 전환기 과정을 거쳐 구서독의 학제에 통합되었다. 구동독의 학제통합은 전환기 조치를 통한 안정적 관리, 동서독 간의 협의 추진, 지역별로 상이한 학제 체제의 도입, 통일 후 사회적 변화 상황에 대한 유연한 대처의 측면에서 긍정적인 특성을 가지고 있다. 반면, 단기간의 개편 추진, 구동독 학제 체제에 대한 고려 미비, 학제 통합 후 내적 인프라 구축의 어려움 등의 한계를 나타냈다. 통일독일의 학제통합 과정 사례는 남북한 통일 후 교육통합을 준비해야 하는 우리에게 학제통합의 안정적 추진을 위한 방안의 수립, 북한 학교체제에 대한 면밀한 검토, 학제통합에 따른 내적인프라 구축 방안 마련 등이 필요하다는 시사점을 제시한다.

Generally, the system of calculation for the multi-path ultrasonic flow meters can be divided into two methods by how to get the mean velocity, namely, weighting and direct method. Weighting-method derive the mean velocity through modeling in theoretical velocity profile. Direct-method derive the mean velocity though actual flow distribution. The system of calculation varies with maker's transducer configuration and integration method. Each system has merits and demerits. This paper describes the system of integration that calculates line velocity over cross-section of the circular pipe. Flow rate mr discussed in this paper is a difference between theoretical flow rate and integrated flow rate according to values of Reynolds number in symmetric flow field or theoretical flow rate and integrated flow rate according to rotated model in asymmetric flow field.

Electric Power Steering (EPS) mechanism has become widely equipped in passenger vehicle due to the increasing environmental concerns and higher fuel efficiency. This paper describes the development of concurrent simulation technique and simulation integration technique of EPS control system with a dynamic vehicle system. A full vehicle model interacting with EPS control algorithm was concurrently simulated on a single bump road condition. The dynamic responses of vehicle chassis and steering system resulting from road surface impact were evaluated and compared with proving ground experimental data. The comparisons show reasonable agreement on tie-rod load, rack displacement, steering wheel torque and tire center acceleration. This concurrent simulation capability was employed fur EPS performance evaluation and calibration as well as for vehicle handling performance integration and synthesis.

This study focuses on MRO e-Marketplace and attempts to research how companies select the structure of e-Marketplace governance and how it influences purchasing performance. Furthermore, a longitudinal study is conducted to analyze the dynamic relationship between variables in our research model. The research gives the following results. First, as the utilization level of e-Marketplace increases, the level of relational exchange between purchasing company and e-Marketplace increases. The increased utilization level enhances purchasing efficiency rather than reducing purchasing price. Secondly, as the level of relational exchange between purchasing companies and e-Marketplace increases, system integration increases, whereas supply externality decreases. Accordingly, system integration improves purchasing efficiency, whereas the low supply externality does not help lower purchasing price. Third, compared to the initial growth stage, the stable stage of e-Marketplace has the significantly increased level of relational exchange and purchasing efficiency through system integration, rather than the reduction of purchasing price by supply externality.

An integration system with multi-measurement sets can be realized via combined application of a centralized and federated Kalman filter. It is difficult for the centralized Kalman filter to remove a failed sensor in comparison with the federated Kalman filter. All varieties of Kalman filters monitor innovation sequence (residual) for detection and isolation of a failed sensor. The innovation sequence, which is selected as an indicator of real time estimation error plays an important role in adaptive mechanism design. In this study, the centralized Kalman filter with adaptive measurement fusion is introduced by means of innovation sequence. The objectives of adaptive measurement fusion are automatic isolation and recovery of some sensor failures as well as inherent monitoring capability. The proposed adaptive filter is applied to the GPS/SDINS integration system with an additional sensor. Simulation studies attest that the proposed adaptive scheme is effective for isolation and recovery of immediate sensor failures.
