Test effort estimated so far is as a by-product of the development effort estimation activity which is based on the FP, UCP, COCOMO model, or calculated data from the project knowledge base which is containing test effort information for the test phase on software development life cycle. In this paper, test effort estimation model and calculating procedures are suggested, which is independent from software development effort estimation model. Generally test efforts is depends on the number and the complexity of test cases, and also maturity of test organization that performs test activities, such as integration test, system test, acceptance test and so on. The estimated results with the suggested test effort estimation model has deviation of 4.7% compare to the corresponding test efforts generated by the development effort estimationprocedures. The suggesting model will be accurate more and more with refinements of coefficients which reflect the technical and environmental maturity level of test organization, and also including the software complexity level of projects.

Korean Administration has launched the KIT(Korean Information Infrastructure) project to strengthen national competitiveness and to improve people's quality of life in preparations for the coming information society in the 21s1 century. It is estimated of 3.19 trillion won for the KII construction starting from 1995 by 2010. The KII is to be implemented in three major stages: deployment such as Network test bed, Government network, and Public network. This paper shows overall trends of domestic and foreign information and telecommunication market, and achievements and issues of the 1st stage trials. This paper suggests some considering points for the successful deployment of the KII project.

This study developed a verification and certification method of technologies of green infrastructure (GI) and low impact development (LID) that gained interest recently. The outdoor testbed used in this study consisted of a building type, a road type, a parking lot type, a rain garden type and a bioretention type. Indoor test facilities were ready for testing using hydrology efficient analysis, pavement and soil analysis and water environment analysis. The development of outdoor and indoor test facilities were used to certify the efficiency of GI & LID technologies, and this was expected to contribute to the activation of the related projects by providing reliable data for the application of GI & LID techniques.

Existing environmental measuring devices mainly focus on electromagnetic wave and eco-friendly product certification and durability test, and sensor reliability verification and verification of measurement data are conducted mainly through sensor performance evaluation through type approval and registration, acceptance test, initial calibration, and periodic test. This platform has established an ICT-based environmental monitoring sensor reliability verification system that supports not only performance evaluation for each target sensor, but also a verification system for sensor data reliability. A sensor board to collect sensor data for environmental information was produced, and a sensor and data reliability evaluation and verification service system was standardized. In addition, to evaluate and verify the reliability of sensor data based on ICT, a sensor data platform monitoring prototype using LoRa communication was produced, and the test was conducted in smart cities. To analyze the data received through the system, an optimization algorithm was developed using machine learning. Through this, a sensor big data analysis system is established for reliability verification, and the foundation for an integrated evaluation and verification system is provide.

In order to monitor internal risk factors such as fire, terror, etc. on the subway station, the surveillance systems using CCTV and various kinds of sensors have been implemented and recently, introduction of surveillance systems using an advanced IT technology, sensor network technology is tried on several areas. Since 2007, Korean government has made an effort to develop the intelligent surveillance and monitoring system, which can monitor fire, intrusion, passenger congestion, health-state of structure, etc., by using wireless sensor network technology and intelligent video analytic technique. For that purpose, this study carried out field wireless communication environment test on Chungmuro Station of Seoul Metro on the basis of ZigBee that is considered as a representative wireless sensor network before field application of the intelligent integrated surveillance system being developed, arranged and analyzed and ZigBee based wireless communication environment test results on the platform and waiting room of Chungmuro Station on this paper. Results of wireless spectrum analysis on the platform and waiting room showed that there is no radio frequency overlapped with that of ZigBee based sensor network and no frequency interference with adjacent frequencies separated 10MHz or more. As results of wireless data transmission test using ZigBee showed that data transmission is influenced by multi-path fading effect from the number and flow rate of passengers on the platform or the waiting room rather than effects from entrance and exit of the train to/from the platform, it should be considered when implementing the intelligent integrated surveillance system on the station.

국내 제약산업의 경쟁력을 제고시키기 위해서는 신약의 심사/허가 기간을 단축시켜 급변하게 변하는 글로벌 제약시장에서 경쟁 우위적 위치를 선점할 수 있도록 기회를 제공할 수 있도록 체계 개선이 시급하다. 신약허가를 위해서는 임상시험 결과에 대한 안전성과 유효성 등에 대한 심사가 수행되게 된다. 하지만 현재 신약허가를 위해서 제약사와 임상시험수탁기관(Contract Research Organization, CRO)에서 데이터 정보체계인 Domain, Variable 및 Parameter 등의 표준을 따르지 않고 다양한 유형의 임상정보데이터를 심사기관에 제출하고 있어 이로 인한 심사기간 증가와 심사업무 비효율성을 야기시키고 있다. 따라서 본 연구에서는 국제민간기구인 CDISC (Clinical Data Interchange Standards Consortium)에서 제정한 글로벌 임상데이터 표준인 CDISC 표준을 준용한 국내 임상시험정보관리 체계 (eCTD 시스템)및 의약품 전주기적 관리체계를 제시하고자 하며, 본 연구를 통한 기대효과로는 국제표준의 임상정보관리 인프라 구축으로 인한 국내 신약개발 및 해외 진출 환경을 마련하여 글로벌 시장선점의 기회를 제공할 수 있고, 규제기관 차원에서는 의약품 허가, 심사업무의 효율성 증가는 물론 전주기적 의약품 안전관리체계를 마련할 수 있을 것으로 사료된다.
