The imported foods, which are imported and sold domestically, are on the rise every year, and the scale is expected to be larger, including processing the imported raw materials. However, the origin of raw materials is indicated when declaring cargo for finished products of agricultural products, but the standardization of inspection information management system for raw materials is insufficient. In addition, there is a growing concern about the presence of residual pesticides or radioactivity in raw materials or products, and customer want to know production history information when purchasing agrifoods. It manages the hazard analysis of imported agricultural products, but most of them are global issues such as microorganisms, residual pesticides, food additives, and allergy components, etc. Therefore, it is necessary to share among the logistics entities in the entire transportation process the related data. Additionally, to do this, it needs to design an architecture and standardize business model. In this paper, it defines the architecture and the work-flow that occurs between the business process for collecting, processing, and processing information for tracking the status of imported agricultural products by steps, and develops XML message with UBL and the extracted conceptual information model. It will be easy to exchange and share information among the logistics entities through the defined standard model and it will be possible to establish visibility, reliability, safety, and freshness system for transportation of agricultural products requiring real-time management.

그간 다양한 제조업에서 발생한 후발국가의 '추격'에 대한 연구가 다수 이루어졌다. 특히 최근에는 추격을 위한 기회의 창 관점에서 새로운 후발국가에 의한 추격의 반복과 그에 따른 산업 시장 주도권의 이전을 논의하기 위한 '추격 사이클' 이론이 제시되어 몇몇 산업과 시장에서 발생한 주도권 이전에 관한 실증 연구가 등장하기 시작하였다. 그러나 산업 시장 주도권 이전 현상은 이미 광범위하게 일어나고 있으며, 이에 대한 논의의 심화와 이론의 발전을 위해서는 심층적인 실증 연구가 지속적으로 등장할 필요가 있다. 이에 따라 본 연구에서는 중국 굴삭기 시장에서 발생한 우리나라에서 중국으로의 주도권 이전의 원인과 그 과정을 추격 사이클 이론에서 제시한 세 가지 기회의 창, 즉 기술적 기회의 창, 수요적 기회의 창, 그리고 정책 제도적 기회의 창과 이에 대한 우리나라와 중국 굴삭기 산업의 전략적 대응 간 결합을 통해 고찰하였다. 먼저 기술적 기회의 창 관점에서는 굴삭기 아키텍처의 모듈화가 완제품 생산에 필요한 기술적 지식의 장벽을 낮추고 기술 학습 속도를 높임으로써 중국 굴삭기 산업의 추격과 시장 주도권 확보에 긍정적인 영향을 미친 것으로 나타났다. 한편 중국 정부의 수요산업(건설업) 육성 정책과 핵심 부품의 수입 관세 철폐, 공용 부품 표준화 정책과 같은 정책 제도적 기회의 창과 이에 대한 중국의 적극적 대응 또한 시장 주도권 이전에 긍정적인 영향을 미침을 확인하였다. 마지막으로 수요적 기회의 창의 관점에서는 2010년 이후 미니 소형 세분시장의 급속한 확대에 대한 중국의 전략적 대응이 산업 주도권 이전에 큰 영향을 미침을 발견하였다. 본 연구는 추격 사이클 이론에 대한 새로운 실증을 제시함으로써 향후 본 이론의 발전에 기여할 것으로 기대된다. 또한 본 연구 결과는 중국의 추격에 직면하였거나 이미 주도권을 넘겨준 우리나라의 제조업의 위기 극복 및 지속가능한 성장을 위한 전략과 정책 수립의 중요한 지침으로 널리 활용될 것으로 기대된다.

Ship autonomous navigation is designated as what computerizes mental faculties possessed of navigation experts, which are building navigation plans, grasping the situation, forecasting the fluctuation, and coping with the situation. An autonomous navigation system, which consists of several subsystems such as navigation system, a collision avoidance system, several data fusion systems, and a motion control system, is based on an intelligent control architecture for the sake of integrating the systems. The motion control system, which is one of the most essential system in autonomous navigation system, controls its propulsion and steering gears to move the ship satisfying its hydrodynamic characteristics. This paper is the study on the ship movement control system and its implementation which are totally developed and run on virtual-world system. Receiving the high-level control values such as a waypoint presented from the collision avoidance system, the motion control system generates them to low-level control values for propulsion and steering devices. In the paper, we develop a ship motion controller using Oldenburger's theory based on mathematical fundamentals, and simulate it with various scenarios in order to verify its performance.

The purposes of e-Government are to connect government agencies without boundary, and to deliver better quality e-services to citizens. The frontier countries try to reach the e-Government goals using Government Interoperability Framework(GIF). Even though Korea also has interoperability regulations, that is obscure. So we have some limitations to take the e-Government interoperability advantages. This study analyzes the cases of advanced countries (EU, U.S., U.K., and Australia), and reviews Korea's regulations. After that, we suggest EA based Korean e-Government Interoperability Framework(K-GIF), that is to manage the interoperability from business to information technology over the whole IT life cycle.

Along with the growth of u-Healthcare, we propose a security enhancement based on network separation for CloudHIS with for handling healthcare information to cope with cyber attack. To protect against all security threats and to establish clear data security policies, we apply desktop computing servers to cloud computing services for CloudHIS. Use two PCs with a hypervisor architecture to apply physical network isolation and select the network using KVM switched controller. The other is a logical network separation using one PC with two OSs, but the network is divided through virtualization. Physical network separation is the physical connection of a PC to each network to block the access path from both the Internet and the business network. The proposed system is an independent desktop used to access an intranet or the Internet through server virtualization technology on a user's physical desktop computer. We can implement an adaptive solution to prevent hacking by configuring the CloudHIS, a cloud system that handles medical hospital information, through network separation for handling security enhancement.

The paper is a study to develop and verify a blood glucose level prediction model based on biosignals obtained from photoplethysmography (PPG) sensors, ICT technology and data. Blood glucose prediction used the MLP architecture of machine learning. The input layer of the machine learning model consists of 10 input nodes and 5 hidden layers: heart rate, heart rate variability, age, gender, VLF, LF, HF, SDNN, RMSSD, and PNN50. The results of the predictive model are MSE=0.0724, MAE=1.1022 and RMSE=1.0285, and the coefficient of determination (R²) is 0.9985. A blood glucose prediction model using bio-signal data collected from digital devices and machine learning was established and verified. If research to standardize and increase accuracy of machine learning datasets for various digital devices continues, it could be an alternative method for individual blood glucose management.
