In this study, the adaptive triangular beam method(ATBM) considering different sound reflection coefficients and angles of a triangular beam on two or more planes as well as diffraction effect is suggested. The ATBM, subdividing a tracing triangular beam into multiple triangular beams on reflection planes, gives reliable and convergent sound-field analysis results without the dependancy on the number of initial triangular beam segmentation to search sound propagation paths from source to receiver. The validity of the method is verified by the comparison of numerical and experimental results for energy decay curve and steady-state sound pressure level of rooms having direct, reflective and diffractive sound paths.

As a society advances and develops more rapidly, there is a corresponding increase in an aging population; and therefore, transportation and transportation needs develop in a complicated way. In these times, medical rehabilitation services are required and the demands for these services will increase as time passes. Moreover, the scope of disability as defined by the government has been expanded owing to the welfare policy for the disabled. Therefore, the number of disabled who require medical services is on the rise. Along with an increase in medical rehabilitation demands, the necessity for medical rehabilitation increases as well and its role becomes more diverse on a wider spectrum. However, architectural studies on rehabilitation facilities have been insufficient and there are many problems currently in facilities operations. This study aims to present a spatial organization system along with required space that would form the basis for the most effective spatial plan and facility operation for rehabilitation hospitals.

The number of share houses has increased in Korea, and social recognition of this type of housing is also growing. In order to review current conditions and housing systems for share houses, an analysis of rooming house, a type of share house that is built overseas, was carried out. This study focused on studying rooming houses of Canada. Residents occupy in rooms and share common spaces with other tenants in rooming houses. The purpose of this research is to study planning guidelines, systems, operation management of rooming houses and the process and role of public and citizen participation. Based on characteristics of planning guidelines and operation management for rooming houses, implications which can be used for setting institutional and planning foundations for share houses in Korea have been presented through this research.

Hospital architectures, as a function-oriented architecture, have a great influences on the functional program and spacial allocation for a great number of rooms and departments. Particularly, spacial allocating analysis is depends on various external forces, such as hospital-size, relationships for the others, ownerships, operating methods, long-term masterplan as well as researchers' methods. Furthermore, as there is focusing on architectural design basis rather than architectural planning In recent Korean architectural field, adequate analysing methodology of spacial allocation for the design process is needed. This paper analyzes architectural drawings for 8 Korean hospitals which constructed in recent 20 years in aspects of the spacial allocation for inner spaces and then, presents areal composition and pattern of spacial allocation for researching hospitals.

In this study, we investigate the non-reacting and reacting performance of single nozzle for post H class gas turbine by using commercial CFD tool, CONVERGE, based on adaptive mesh refinement. By varying swirl number and mixing length of base nozzle design. Through the numerical analysis, basic phenomena can be well described with respect to fuel concentration for non-reacting flow, temperature distribution, velocity vector and combustion outlet temperature distribution for reacting flow. However, there are rooms for improvements in model accuracy by comparing test results. Comparison between numerical analysis are planning for further study.

Background: Although the number of cancer patients increase, the resources for cancer management are not increased. If the outpatient chemotherapy administration room is operated, the shift of patients from inpatient 10 outpatient is occurred. So the capacities for chemotherapy increased and the shifted rooms were occupied with new non-chemotherapy patients. The income of the hospital increased. The purpose of this study was to assess usefulness and cost-effectiveness of the outpatient-chemotherapy adminstration model. Method: There are six beds, two chairs and two nurses and one personnel in the outpatient chemotherapy room. The satisfaction study by patients/family and doctors and the cost analysis over 12 months, by comparing costs of chemotherapy administration at outpatient chemotherapy room with inpatient at ward and inpatient-nonchemotherapy at ward were done. Results: The 97.1 percent of patients/family and the 94.4 percent of doctor who involved chemotherapy were satisfied with outpatient chemotherapy administration. The 91.7% of doctors said there were no differences in treatment outcome between outpatient and inpatient chemotherapy administration. The average number of patients in outpatient chemotherapy room increased from 10.7 to 15.4 but in inpatient from 19.4 to 18.3. The average number of inpatient chemotherapy were not changed related to increase of the average number of outpatient chemotherapy. The profit between outpatient chemotherapy and inpatient chemotherapy administration was 45,344,710 won and the profit between outpatient chemotherapy and non chemotherapy treatment was -185,294,614 won. Conclusion: The outpatient chemotherapy administration model is good for patients/family, doctors and hospital partially. But the hypothesis described above was not correct. The process of cancer patients treatment were from diagnosis and treatment to first administration of chemotherapy. So the shift from inpatient to outpatient was not occurred. In economic aspect, the profit between outpatient chemotherapy and non chemotherapy treatment was in the red. As the level of health care fees was so low, the hospitals hesitate operating the room of outpatient chemotherapy. It is necessary to raise the level of health case fees for outpatient chemotherapy administration.
