The purpose of this study is to evaluate and make a comparison between the Ordinary Moment Resisting Frames using different analytical joint model for the Nonlinear response. For this purpose, 3-story structure was designed according to NEHRP 1994 Guidelines. And the center-line dimension model and model considering panel zone were used as analytical model for the structure. Nonlinear Static Procedure and Nonlinear Dynamic Procedure were used to evaluate seismic capacities and demands. The limitation in FEMA 273 was used as the variable number to predicte seismic demands of OMRFs. This analytical studies were performed with DRAIN-2DX modified by Shan Shi. Using the above results, the performance evaluation and seismic demands of OMRFs shall be performed. Finally NSP and NDP shall be compared.

A two-level displacement-based design procedure is developed. To obtain the displacement demands, elastic spectra for occasional earthquakes and inelastic spectra for rare earthquakes are used. Minimum global stiffness and strength to be supplied to the structure are based on specified maximum permissible drift limits and on the condition that the structure responds within the elastic range for occasional earthquakes. The performance of the structure may be assessed by an inelastic push-over analysis to the required displacement and the evaluation of damage indices. The approach is applied to the design of a five-story reinforced concrete coupled wall structure located in the most hazardous seismic region of Argentina. The inelastic dynamic response of the structure subjected to real and artificially generated acceleration time histories is also analyzed. Finally, advantages and limitations of the proposed procedure from the conceptual point of view and practical application are discussed.

At present, the necessity of new design guidelines, evaluation and operation system for school facilities are on the rise according to re-edition of school curriculum in Korea. Moreover, it is necessary to procedure of the design, an institutional device and an ex post facto evaluation system for school facilities as a public building with the space planning that is suitable for various situations, which are able to collect users' various demands and opinions. Under the present situation, England has introduced and operated DQI system for the users' participation design of its. The present study will derive the meaning DQI system of England and how to operate it, and percuss the possibility of the application of design procedure of the education facilities in Korea.

Nursery is a very important space for the development and growth of children. Domestic national nurseries mostly have uniform space composition, and there is no significant difference from the general architecture. Therefore, this study focused on presuming the cause of uniformity in domestic nursery space configuration through analysing the competition guidelines. For this purpose, we reviewed the procedure of the competitions and collected 57 competition guidelines for the last 10 years. The competition guideline was divided into design guidelines and evaluation items, and each of them were analysed focused on the contents of the items and the changes over time. The derived results suggested the problems which seem to affect the uniformity of the domestic nursery in three aspects: design guidelines, evaluation items, and the current procedure of nursery competitions.

The IAEA launched the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) and developed the INPRO Methodology to provide guidelines and to assess the characteristics of a future innovative nuclear energy system in areas such as safety, economics, waste management, and proliferation resistance. The proliferation resistance area of the INPRO Methodology is reviewed here, and modifications for further improvements are proposed. The evaluation metrics including the evaluation parameters, evaluation scales and acceptance limits are developed for a practical application of the methodology to assess the proliferation resistance. The proliferation resistant characteristics of the DUPIC fuel cycle are assessed by applying the modified INPRO Methodology based on the developed evaluation metrics and acceptance criteria. The evaluation procedure and the metrics can be utilized as a reference for an evaluation of the proliferation resistance of a future innovative nuclear energy system.

A construction project with a total construction cost of over 10 billion KRW should be evaluated whether construction works are appropriately executed. The evaluation is carried out on quality management, process management, construction management, safety management, environmental management. The implementation period is within 60 days after completion of construction of the construction, from the time when the construction rate of the construction work has progressed by more than 90% to the construction cost. However, the participating construction engineers should prepare the evaluation within the period according to the evaluation criteria, but there are difficulties in preparation for the evaluation due to the reasons such as the change of engineers in charge and loss of data. Therefore, this study proposes the procedure of construction evaluation and adjusts timing of construction evaluation.

8 cases of the esophageal perforations were treated at the department of thoracic surgery, Chungnam National University Hospital during the period from July, 1980 to Dec., 1982. The causes of the perforation were various; swallowed a piece of glass, stocking pin, coiled wire, compressed air blow, strenuous vomiting, dog bite, tiller accident, and endoscopic procedure. The perforation sites were cervical esophagus in 3 cases, upper thoracic in 2 cases and lower thoracic in remains. We have performed following surgical procedure; Incision and drainage for cervical abscess, closed thoracostomy, thoracotomy and debridement, esophagoscopy and gastrostomy. Two cases were died. The causes of death were massive bleeding and sepsis.

In recent years, significant advances have been made enabling travel demand analysis and network design methods to be used as increasingly realistic evaluation tools. What has been lacking is the integration of travel demand analysis with network design models. This paper reviews some of advanced (integrated) modeling approaches and presents future research directions of integrated modeling system. To design urban transportation networks, it is argued that the travelers' free choice of mode, destination and route should be introduced into transportation network design procedure instead of assuming that trips from a zone to a workplace are fixed or deriving them in a normative procedure to achieve hypothetical system optima.

This paper describes the method of evaluating the elastic modulus of soil medium by using the Circular Plate Loading Test. The elastic foundaton is considered to be the elastic half-space. The stiffness matrix of elastic half space is drived using Boussinesq's analytical soulution. A numerical examples are presented to verify the validity of this procedure. Also, the numerical results are compared with others by the existing study results. The procedure proposed in this theses can be applied to the design of paving concrete resting on the elastic foundation.
