한국 정치와 북핵 문제

신기현 朝鮮大學校 統一問題硏究所 2005 統一 問題 硏究 Vol.20 No.2

이 글의 목적은 2005년 시점 상황에서 한국정치권은 북핵문제에 어떻게 인식하고 있는가에 관한연구이다. 본 논의에서는 북핵현안을 둘러싸고 나타난 주요정당의 공식자료를 토대로 그들의 인식을 검토하고 국회의원들을 대상으로 실시하여 발표한 여론조사 자료를 재검토하여 국회내에서 북핵관련 결의안 제출과정에서 나타난 회의자료를 검토하는 방식을 택했다. 2005년 2월에 국회통일외교통상위원회에 북핵관련 결의안들이 제출되고 검토된 결과 7월에 대안형태로 '한반도 평화실현과 6ㆍ15 공동선언의 발전적 계승을 위한 결의안'을 가결시키기 위한 북핵문제는 고착상태에 빠져 있었다. 국회에서도 이러한 문제에 특별히 영향을 미칠 수 있는 수준이 아니었기에 결의안을 채택하는 수준에 머물렀다. 북핵문제에 대한 인식은 위기를 극복하는 과정에서 여야가 있을수 없다는 것이 합의를 도출하는 주된 동인이었다고 평가할 수 있다.

신기현,홍완기 건국대학교 1995 學術誌 Vol.39 No.2

A new mathematical dynamic model which relates tension change, motor-speed change and roll-gap change is developed. Through the computer simulation of this model, parameter sensitivity, the tension transfer phenominon, and static and dynamic characteristics of strip tension were studied. Guidelines are developed to help one selecting locations of the master-speed drive in a multi-drive speed control for tension adjustment and reducing the effect of interaction between tension and roll gap control.

A real-time distributed control software was needed to operate the high-speed continuous processing line. A real-time software for tension control in the continuous processing line was designed and implemented using the Vxworks real-time scheduler. Various techniques of real-time software design(e. g., tasking, inter-task communications, behavioral requirements, task specifications, etc.) were implemented in the design of real-time tension control software. A time scheduling technique for periodic tasks("dynamic task-delay technique") in the VxWorks scheduler is proposed. A real-time simulation for a typical tension control system was carried out. The dynamic task-delay technique guaranteed the predefined frequencies of periodic tasks of the tension control system whereas the "static task-delay technique" could not.

The traffic engineering consists of traffic management, capacity management and network planning. In this paper, we present the capacity management function in traffic engineering for next generation multimedia internet services. The link capacity design, shortest-route design and multiple-time network design model is presented. Finally, day-load variation design model and traffic forecasting/reservation model for internet traffic are introduced.

The thermal stability and crystallization process of amorphous Fe Si P alloys were studied by D.S.C and x-ray diffractometer. The results are as follows; 1) The amorphous forming range of Fe Si P alloys is O x 8. 2) Phase transformation by the crystallization occurs as follows ⅰ) x=2,4 ; amorphous → α-Fe(b.c.c) + Fe₃P(b.c.t) ⅱ) x=6,8 ; amorphous → amorphous + FeP → Fep + Fe₂P(h.c.p) → Fe₃P(b.c.t) + α-Fe(b.c.c). 3) The crystallization temperature and activation energy for crystallization are increased with increasing Si contents and presented max 718K, 110Kcal/mole at x=4, respectively and then decreased with increasing Si contents.

We present a case of perforating granuloma annulare which appeared as multiple small papular lesions with central umbilication on the dorsum of both foot and sides of foot, The patient was a 12 year-old female child who had slightly tender lesions of one month's duration. Histologic study showed perforation of the epiderrnis and release of the abnormal necrobiotic material transepiderrnally. The epidermal perforation communicated with area of granuloma annulare in the dermis that consist of necrobiotic collagen surrounded by palisading mononucler phagocytes in the dermis. All the lesions resolved spontaneously with a slight hyperpigmentation in 4 months. She also had erythematous tender nodules, which diagnosed as erythema nodosum, on both shins. The lesions responded to potassium iodide 1.0g for 2 weeks.

Current information society requires effective ways to process multimedia data like image, audio, video and so on, Many public of private information providers gather, store multimedia information and supply a different kind of multimedia data to users in everywhere. Most of users nowadays access multimedia data via internet. Audio and video data are usually transmitted to users by using streaming technology for instant replay. In this paper, we investigate database design techniques for effective retrieval of video segment and replay method of retrieved videos, Especially we shows the design and implementation technique for closed captioning of streaming file.

9-12%Cr steel are getting increasing attention for expanded application as high temperature materials applicable for gas turbine compressors, steam turbine rotors, blade and casing. For efficient and extensive application of 9-12%Cr steel, the data in addition to the improvement of mechanical properties on the correlation of microstructural evolution and mechanical properties are inevitable and thus the investigation in this study is performed for the determination for the specimens heat-treated at 600, 650 and 700℃ for 1000, 3000 and 5000hrs. The microstructure of as-received specimen was tempered martensite, with a high dislocation density and secondary phases. Upon high temperature heat-treatment, the martensite lath got larger and dislocation density decreased resulting the reduction of the strength. In addition, sharp growth of secondary phases was observed in the specimen heat-treated at 700℃ for 5000hrs. A specimen aged at 600℃ and 650℃ Laves phase was observed. The hardness showed close relationship with the secondary phase particle and dislocation density.

In a web winding process, the contact roll plays many important roles in air entrainment control and WIT(Wound In Tension) regulation. The behavior of the contact roll significantly affects the winding tension characteristics specifically at the time of contact and separation when the tangential velocities of contact roll and winding roll are not synchronized. A new mathematical model which includes the behavior of the web tension, the winding roll, the carriage and the contact roll is derived for the control of the winding tension. By using the model derived, a non-linear PID(NPID) controller is designed to control the winding tension at the time of contact and separation between the contact roll and the winding roll. Computer simulation study showed that the performance of the winding system with the NPID controller was significantly improved compared with that of a system with PID controller.
