This study aims to validate the effectiveness of CAVE system with an Arm-Master in the evaluation of virtual prototypes. A virtual kitchen with a refrigerator was presented in the CAVE system. Subjects put in and pull out virtual objects by using the Arm-Master. Twelve subjects, six males and six females, participated in the six experimental conditions : three types of refrigerator door grips and two reaction forces. After each trial, subjects evaluated a door grip of the virtual refrigerator in terms of easiness of operation, similarity in force, presence etc. The results show the mean values of vortical-type door grips are greater than the horizontal pocket-type door grip. Also the subjects preferred 5N in the reaction force of the Arm-Master rather than 15 N when they open and close virtual door. Unexpectedly, female subjects significantly marked low scores in the evaluation terms compared ruth mali subjects. It explains the Arm-Master should be modified much more if it works effectively in design evaluation.

A cabinet-door integrated finite element model for a built-in side-by-side refrigerator with an ice dispenser and home bar was constructed, and its deformation was analyzed by ANSYS. As loads, the food load in the shelf and baskets, and thermal load occurring during the normal operation condition were considered. From results of the analyses, the door height difference (DHD) and door flatness difference (DFD) between the two doors, and the increase in the gap of the door gasket, which affects the sealing of cool air in the cabinet, were derived. As results of an evaluation of the differences, the DHD and DFD under the assembled condition satisfied the acceptance criteria of the manufacturer. The food and thermal loads increased the DHD and DFD due to thermal deformation, and the DFD increased significantly. In addition, the increase in the gap of door gasket located between the cabinet and doors was derived from the results of displacements under the food and thermal loads. The evaluation showed that the maximum increase in gap appeared at the left edge of the freezing compartment gasket, which satisfied the acceptance criteria of the manufacturer.

Purpose: The need for the rapid evaluation and treatment of emergency department patients with major trauma is essential. A computerized physician order entry (CPOE) system can improve communication and provide immediate access to information with the goal of reducing ED time delays. The aim of this study was to report on the operation of a trauma CPOE program and demonstrate its usefulness by comparing time intervals from ED arrival to various evaluation steps before and after implementation of the program. Methods: This was a before-and-after observational study from a single emergency department at an academic center. The CPOE program was implemented for 6 months and compared with the data collected from the pre-CPOE implementation period. The efficacy of the program was assessed by comparing the time difference before and after CPOE implementation based on the following factors: total boarding time in ED, door-to-disposition decision time, door-to-blood-test report time, door-to-X-ray time, door-to-CT time, and door-to-transfusion time. Results: Over a period of 6 months, the CPOE was activated for a total of 17 patients. Total boarding time was reduced significantly after implementation [median, 641.5 minutes (IQR, 367.3-859.3) versus289.0 minutes (IQR, 140.0-508.0) for pre-CPOE vs. post-CPOE, respectively, p< 0.05). Time intervals for all evaluation steps were reduced after implementation of the program. The improvements in the door-to-blood-test and door-to-CT times were both statistically significant. Conclusion: This study demonstrated that a standard CPOE system can be successfully implemented and can reduce ED time delays in managing trauma patients.

Recently, traffic data is analyzed for efficiency of bus operation, D2D(: Door to Door) service, and self-driving of public transportation. However, various studies have been carried out to predict the delay time of public transportation, especially buses, but the research to date has been insufficient due to limitations of simple analysis and data acquisition. In this study, delay time estimation is performed by collecting and processing data such as day of the week, weather, and time of day based on bus operation information. The proposed method in this paper can be applied to autonomous public transport and public traffic control system by improving the accuracy by adding variables in the future.

In Seowon architecture, there are four kinds of space conditions according to the site plan and the figure of education area. The education area has three main buildings such as Kangdang, Dongjae, Seojae. In case Kangdan locates in front of Dongjae and Seojae(so called Junkangdang-Hoojaesa), but in another case Dongjae and Seojae locates in front of Kangdang(so called Junjaesa-Hookangdang). This four space conditions affect to decide the floor plan and the window & door system of Kangdang. In Junjaesa-Hookangdang type, the front and rear wall has more open system than in Junkangdang-Hoojaesa type. In Junjaesa-Hookangdang type the direction of Kangdang is absolutely open to front education area, but in Junkangdang-Hoojaesa type the direction of Kangdang is absolutely open to rear education area. These floor plan aims at making up education area more closely. In window & door system the rear parts of Junjaesa-Hookangdang type have generally opaque system such as Golpanmoon or Panjangmoon, but Junkangdang-Hoojaesa type breaks this rule in order to emphasize front facade of building.

This study presents the evaluation process for door module. Its objective evades the resonance generated at module plate due to the operation of window regulator motor. For this study, the design improvement process is composed of experimental methods having three steps. First step is modal analysis at door assembly status for acquisition of dynamic characteristics which are modal frequency and damping. Second step is a vibration experiment to get the test mode considered an efficiency of window regulator motor. Last step is a vibration measurement by the form of $6{\times}6$ array on module plate. A vibration measurement of 6x6 array form can be got to three analysis results which are a transfer path of vibration using cross correlation function, a vibration map using OA level and a contribution by frequency band using coherent output power spectrum on module plate. These results are applied to SDM(structural dynamic modification) for design improvement to get around the resonance on module plate by the excitation of window regulator motor.

Purpose: The purpose of this study is to investigate the importance of grade decision and role of physical therapist which follows enforcement of elderly long-term residential care insurance system. Methods: One of the data from grade decision meeting in Bukgu, Busan on 2007 which was 88 case of attached finding of doctor was compared with findings of visited investigator. Result: Eighty-four investigation subjects had 186 diseases that included stroke and arthritis, requiring the need for physical therapeutic approaches. In addition, the results of the door-to-door research project in the northern district of Busan showed that there was no match out of 88 subjects who submitted the viewpoint of the doctor. Such a result was produced as the doctors did not diagnose the patient directly, but rather the diagnoses were obtained from guardians and a door-to-door researcher who had a poor understanding of geriatric motion and function. Conclusion: To enforce long-term care successfully, a re-investigation should be performed for the welfare of the aged.
