본 논문에서 국내 항공사고조사를 위한 통합 데이터 관리 시스템 프로토타입 개발을 제안한다. 최근 항공사고 조사 장비의 발전에 따라 사고조사 시스템은 다양한 형태의 jpg, avi, 및 wav 파일 자료들을 수집 및 관리해야한다. 하지만 ECCAIRS 시스템의 경우 항공사고 조사 시 발생하는 다양한 자료를 관리하기 위한 별도의 데이터베이스를 구축하고 있지 못한 상황이며, 국내 항공사고 관리시스템 역시 동일한 문제점을 가지고 있다. 따라서 본 논문에서는 해외 주요 국가의 항공사고보고서 시스템을 분석하고 국내 환경에 적용할 수 있는 방안을 마련한다. 통합 데이터 관리시스템 프로토타입을 통하여 기존 자료와 최근 조사한 자료를 입력을 통하여 성능을 확인하였다. 이 결과를 이용하여 최종 통합 데이터 관리시스템의 완성을 위한 기초 자료로 활용할 예정이다.

This study was designed to compare the performance of liquid-based preparation from the AutoCyte PREP with the conventional cervicovaginal smear in masked split-samples. In randomly selected 840 cases, the conventional smear was always prepared first, and the AutoCyte PREP used the resldual cells on the collecting device. Parallel AutoCyte PREP slides and matched conventional smears were screened in a blind fashion. All abnormals and 10% random normal cases were reviewed by two pathologists in a blind fashion. The Bethesda System was used for reporting the diagnosis and specimen adequacy. The diagnoses from the two methods were agreed exactly in 767(91.3%) of 840 cases. The AutoCyte PREP demonstrated a 25% overall improvement in the detection of squamous intraepithelial lesion(SIL). The ratio of ASCUS to SIL was decreased as 0.45 compared with 1.00 of conventional smear. The AutoCyte PREP produced excellent cellular preservation and superior sensitivity for detection of atypical cells as compared to the conventional smear. It makes us to be able to subclassify ASCUS into from WNL to HSIL. We thought that the AutoCyte PREP method might contribute to increase the detection rate of abnormal cells than conventional methods.

Jet lag can be defined as the cumulative physiological and psychological effects of rapid air travel across multiple time zone. The consequences of jet lag include fatigue, general malaise, sleep disturbances, and reductions of cognitive and psychomotor performance, all of which have been documented in experimental biological and air crew personnel studies. Thus authors tried to study the jet lag of natural travellers by modified self reporting sleep log. Total 61 healthy travellers was studied for 3 days before and 7 days after jet-flights across seven to ten time zone. The eastbound travelling group was 38 persons, aged 19 -70 and westbound travelling group was 23 persons, aged 13 - 69. Sleep onset time, wake-up time, sleep latency, awakening frequency on night sleep, awakening duration on night sleep, sleepiness at wake-up and nap length were evaluated. Our results suggested that the 7 to 10 time zone shift gave significant influence to traveller's sleep-wake cycles. The date which subjective physical condition was recovered on was $5.16{\pm}1.50$ day after arrivals for eastbound, while for westbound, $4.91{\pm}1.62$ day. In eastbound travelling, sleep onset time became later than baselines and could not recover until 7th day. But in westbound, it became earlier than baseline and could recover until 6th day. The mean score of 24-hour sleepiness was greater in eastboumd than westbound. Therefore the eastbound travelling caused more sleep-wake cycle disturbance and daytime dysfunction than westbound travelling. In other parameters, there was no definite difference between east and westbound. From our results, it was suggested that the symptom severity of jet lag was dependent on the travelling direction. To demonstrate more definite evidence, large sized data collections and comparision by age difference were needed.

Cost and time control of projects is important in preventing project failure. However, achieving effective cost and time control in practice is often challenging. The challenges of project cost and time control in practice are investigated by carrying out a questionnaire survey on the top 150 construction contractors in the UK followed by in-depth semi-structured interviews of practitioners from 15 construction companies in the country. Quantitative analysis reveals that design change is the most important factor inhibiting the ability of UK contractors from effectively controlling both the cost and time of construction projects. Four of the top five factors inhibiting effective cost control are also the top factors inhibiting effective time control albeit in a different order. These top factors-design changes, inaccurate evaluation of project time/duration, risk and uncertainty, non-performance of subcontractors and nominated suppliers were also found to be endogenous factors to the project. Additionally, qualitative analysis of the interviews reveals 16 key challenges to prevent for effective project cost and time control in practice. These are classified into four categorised based on where they stem from as follows; from the organisation (1. Lack of integration of cost and time during project control, 2. lack of management buy-in, 3. complicated project control systems and processes, 4. lack of a project control training regime); from the construction management/project management approach (5. Lapses in integration of interfaces, 6. project control not being implemented from the early stages of a project, 7. inefficient utilisation and control of labour, 8. limited time devoted to planning how a project will be controlled at the outset); from the client; (9. Excessive authorisation gates, 10. use of adversarial and non-collaborative forms of contracts, 11. communication problems within client set-up, 12. obstructive client representatives) and; from the project team (13. Lack of detailed/complete design, 14. lack of trust among the project partners, 15. limited time devoted to project control on site, 16. non-factual reporting). The study posits that knowledge of these project control inhibiting factors and challenges is the first step at ensuring they are avoided and enable the implementation of a more effective project cost and time control process in practice.

현재의 인터넷은 폭발적으로 증가하는 다양한 멀티미디어 트래픽의 QoS 제공을 위한 트래픽 엔지니어링 기능을 갖고 있지 않다. 이러한 기능적인 단점들은 현격한 서비스 품질의 저하와 대량의 멀티미디어 서비스와 실시간 서비스 제공을 더욱 어렵게 한다. 이러한 문제를 해결하기 위한 다양한 기술이 개발되고 있다. 현재 IETF(Internet Engineering Task Force)에서 제안한 MPLS(Multi-Protocol Label Switching)기술이 이러한 문제를 해결할 차세대 인터넷의 백본 기술로 가장 유력할 것으로 예상된다$^{[1][2]}$ . MPLS와 같은 고속통신망에서 발생하는 장애는 대량의 데이터 손실과 서비스의 품질을 저하시키게 된다. 그러므로 이러한 장애에 대한 신속한 통신망의 자동복구 기능 및 OAM(Operation, Administration and Maintenance)기능은 필수적이라 할 수 있다. MPLS 통신망은 2계층에 독립적이기에 이에 적용할 장애검출, 장애보고 같은 OAM 기능 또한 다른 계층의 OAM 기능과 독립적으로 동작해야 한다. 본 논문에서는 OPNET 네트워크 시뮬레이터를 기반으로 MPLS 통신망에서의 성능측정과 장애의 검출보고, 장애의 위치 파악을 위한 MPLS OAM의 실험적인 결과를 나타내었다.
