Purpose: As we are facing the global crisis from the climate change and energy depletion, urgent actions are needed to design a integrated sustainable building. This paper suggests that a sustainable design awards can stimulate for architects to bring the cutting-edge ideas into a realized building in comparison to green building certification system. AIA COTE Top 10 design awards, organized and run by AIA(American Institute of Architects) COTE(Committee on the Environment) from 1997, is analyzed as a case study. By researching the core of the AIA COTE Top 10 design awards system in terms of evaluation measures and submission requirements, meaningful suggestions were drawn to supplement Korea Green Building Awards system and to design and realize leading green buildings in Korea. Method: The comparison between AIA COTE Top 10 and Korea Green Building Design Awards was made in terms of evaluation measures, submission requirements, and green building certification systems. Result: This paper finally suggests the following three points in conclusion: 1) Set the standards of evaluation measures reflecting the three aspects(economy, environment, social) of sustainability, 2) Set the qualitative evaluation measures and corresponding submission requirements that can apply in the design awards in comparison to green building certification system, 3) Develop and balance submission requirements in response to evaluation measures to proceed systematic evaluation of the green buildings.

Global Energy Industry's high oil prices persist while their petroleum and gas production areas are entering the decline phase. More and more the drilling facilities used to bore oil from deeper depths are advancing further out into the oceans, which cause the development of "OFFSHORE" ship manufacturer facility's production demands to increase. The "OFFSHORE" ships provide a living space or L.Q (Living Quarters) for crewmen who work on the water far away from any mainland for extended periods of time. This research analyzes the LQ areas and the characterization of interior designs of different types of "OFFSHORE" ships that were built in South Korea. Also using overseas countries' Classification Society, known as "NORSOK," and analyzing their own design guidelines in conjunction with the research, the process of interior design and baseline data research was used to blueprint the new LQ areas. According to the results of the research, where ships get comprised of characteristics and operations by standards of the Classification Society's RULE, has the greatest effect on the design and design method of the LQ area. The research also shows that a conservative shipbuilding market of the Shipbuilding Company and ship owners' feelings are steadily changing to more open mindedness of acceptance. Therefore, the Korean Classification Society has to provide the new design principle to correspond to the international regulations and more various interior design plans of LQ areas needed to be present based on the new design guidelines. The capacity of the South Korean OFFSHORE shipbuilding industry is the world's top leader; however, the interior design of the LQ areas are still based from outdated designs from the 1980's. Hopefully these research results will be the cornerstone to help the shift from the outdated designs of the LQ areas to more practical modern designs.

Purpose: This study aimed to install an RTK-GPS (Real Time Kinematic-Global Positioning System) and IMU (Inertial Measurement Unit) on a tractor used in a farm to measure positions, pasture topography, posture angles, and vibration accelerations, translate the information into maps using the GIS, analyze the characteristics of grass harvesting work, and establish new technologies and construction standards for pasture infrastructure improvement based on the analyzed data. Method: Tractor's roll, pitch, and yaw angles and vibration accelerations along the three axes during grass harvesting were measured and a GIS map prepared from the data. A VRS/RTK-GPS (MS750, Trimble, USA) tractor position measuring system and an IMU (JCS-7401A, JAE, JAPAN) tractor vibration acceleration measuring systems were mounted on top of a tractor and below the operator's seat to obtain acceleration in the direction of progression, transverse acceleration, and vertical acceleration at 10Hz. In addition, information on regions with bad workability was obtained from an operator performing grass harvesting and compared with information on changes in tractor posture angles and vibration acceleration. Results: Roll and pitch angles based on the y-axis, the direction of forward movements of tractor coordinate systems, changed by at least $9-13^{\circ}$ and $8-11^{\circ}$ respectively, leading to changes in working postures in the central and northern parts of the pasture that were designated as regions with bad workability during grass harvesting. These changes were larger than those in other regions. The synthesized vectors of the vibration accelerations along the y-axis, the x-axis (transverse direction), and the z-axis (vertical direction) were higher in the central and northwestern parts of the pasture at 3.0-4.5 m/s2 compared with other regions. Conclusions: The GIS map developed using information on posture angles and vibration accelerations by position in the pasture is considered sufficiently utilizable as data for selection of construction locations for pasture infrastructure improvement.

Education on the physician continues with undergraduate medical education, graduate medical education, and continuous medical education. The countries such as the United States, Japan, the United Kingdom, German, and others are required to undergo training in the clinical field for 2 years after completing the national medical examination, and to become doctors after passing the clinical practice license test. Korea can obtain a medical license and become a clinical doctor at the same time if it passes written and practical tests after completing 6 years of undergraduate medical education or 4 years of graduate school. About 90% of medical school graduates replace clinical practice with 4-5 years of training to acquire professional qualifications, but this is an option for individual doctors rather than an extension of the licensing system under law. The medical professional qualification system is implemented by the Ministry of Health and Welfare on the regulation. In fact, under the supervision of the government, the Korean Hospital Association, the Korean Medical Association, and the Korean Academy of Medical Sciences progress most procedures. After training and becoming a specialist, the only thing that is given to a specialist is the right to mark him or her as a specialist in marking a medical institution and advertising. The government's guidelines for professional training are too restrictive, such as the recruitment method of residents, annual training courses of residents, dispatch rule of the residents, and the quota of residents of training hospitals. Although professional training systems are operated in the United States, the United Kingdom, France, and Germany, most of them are organized and operated by public professional organizations and widely recognize the autonomy of academic institutions and hospitals. Korea should also introduce a compulsory education system after graduating from medical education and organize and initiate by autonomic public professional organization that meets global standards.
