  • An ecosystem-based fisheries management (EBFM) approach becomes more important as an alternative management method for a sustainable development of fisheries domestically and internationally. Many methods of applying a practical EBFM to fisheries management have been investigated, and considerable attention has been given to developing effective indicators of the present status of and changes in ecosystems and putting them to practical use. Among ecosystem indicators, developing socioeconomic indicators for EBFM is particularly important. This is because socioeconomic factors have direct effects on ecosystems, and ecosystems have direct effects on socioeconomic factors. Therefore, it is imperative that socioeconomic indicators are developed and evaluated in order to predict changes in ecosystems and to provide advice for effective fisheries management. This study is aimed to develop socioeconomic indicators which can be combined with biological and ecological indicators, in order to conduct the ecosystem-based fisheries assessment. In terms of socioeconomic indicators, five socioeconomic criteria were considered as important attributes of socioeconomic changes. These criteria include economical production, business conditions, income, market, and employment indicators. For evaluation of newly developed socioeconomic indicators, the Traffic Light System (TLS) method was used. In addition, on the basis of the application of developed indicators to the Korean large purse seine fishery, the socioeconomic conditions of the fishery and the usefulness of the indicators were evaluated and management implications were discussed.

  • The needs for digital models of real environment such as 3D terrain or cyber city model are increasing. Most of applications related with modeling and simulation require virtual environment constructed from geospatial information of real world in order to guarantee reliability and accuracy of the simulation. The most fundamental data for building virtual environment, terrain elevation and orthogonal imagery is acquired from optical sensor of satellite or airplane. Providing interoperable and reusable digital model is important to promote practical application of high-resolution satellite imagery. This paper presents the new research regarding representation of geospatial information, especially for 3D shape and appearance of virtual terrain, and describe framework for constructing real-time 3D model of large terrain based on high-resolution satellite imagery. It provides infrastructure of 3D simulation with geographical context. Details of standard-based approach for providing infrastructure of real-time 3D simulation using high-resolution satellite imagery are also presented. This work would facilitate interchange and interoperability across diverse systems and be usable by governments, industry scientists and general public.

  • 이 논문은 블루투스 장치의 전 세계적으로 사용되는 무허가 ISM 대역의 2.4GHZ로 동작한다. 이 대역은 널리 사용되고 있지만, 블루투스 이외의 수많은 다른 시스템들이 이 주파수대를 사용하고 있고 마이크 웨이브 오븐과 같은 잡음원이 이 주파수대를 차지하고 있기 때문에 오히려 방해가 심한 주파수 대역이 되고 있다. 블루투스는 이와 같이 방해가 심한 전파환경을 극복하기 위해 빠른 주파수 호핑법과, 에러방지 및 정정기술을 사용하고 있다. 이와 같은 상황에도 불구하고, 저가의 블루투스 시스템이 신뢰성 있고 안정하게 하기 위해 언급할 몇 가지 중요한 설계 상 문제점이 있고 시스템 설계시 몇 가지 면밀한 주의가 필요하므로 연구하고자 한다.

  • In order to realize the commercial application of HTSC materials, it is necessary to develop the fabrication process of high Tc oxide superconductor materials with desired shape and for practical application and high critical current density as well as good mechanical strength which can withstand high lorenz force generated at high magnetic field. Much studies have been concentrated to develop the fabrication technique for high critical current density but still there are a lot of gap which should be overcome for large scale application of HTSC materials at liquid nitrogen temperature. Recently some new fabrication techniques have been developed for YBaCuO bulk superconductor with high mechanical strength and critical current density. In this project, the establishment of fabrication condition and additive effects of second elements were examined so as to improve the related properties to the practical use of YBaCuO superconductor, and we reported the production of the YBaCuO high Tc superconductor by the pyrolysis method.

  • In the MEP(Mechanical Electrical and Plumbing) field, the utilization of BIM-based drawings is lower than in the architectural and structural sectors, and the limited BIM collaboration problem caused by different levels of BIM utilization in each field is becoming a serious problem in adoption and utilizing BIM. Therefore, this study analyzed the current status of BIM application in the field of mechanical equipment in the construction industry and analyzed the practical problems and limitations of adoption and utilizing BIM from a corporate perspective based on Delphi analysis techniques. Based on the results of the analysis, the limitations of the current MEP BIM application were classified into economic, technical, institutional, and social factors to derive detailed items, and, accordingly, the improvement measures were classified as institutional, policy, and technical measures. As a result, the company intends to maximize the value of BIM utilization in the MEP field by presenting improvement plans to activate BIM in the field of mechanical equipment based on the opinions of the company, thereby laying the foundation for BIM in the construction industry by creating a collaborative BIM environment for each sector in the domestic construction industry.

  • The practical application of REBCO coated conductor (CC) tapes, vital for energy transmission (e.g., cable application) and high-field magnets (e.g., coil application), necessitates efficient and simple quality assessment procedures. This study introduces a systematic approach to assess the electromechanical properties of REBCO CC tapes under 77 K and self-field conditions. The approach involves customized tensile and bending tests that clarify the critical current (Ic) response of the CC tapes under mechanical loads induced by tension and bending. This study measures the retained Ic values of commercially available GdBCO CC tapes under 250 MPa tensile stress and 40 mm bending diameter. Through experimentation, the study demonstrates the resilience of these tapes and their suitability for applications. By presenting a simplified stress-based analysis and a bending test of the tapes, the study contributes to effective quality assessment methods for the development of practical superconducting products.
