In recent years, medical procedures have become more complex, while financial pressures for shortened hospital stays and increased efficiency in patient care have increased. As a result, several shortcomings of present film-based systems for managing medical images have become apparent. Maintaining film space is labor intensive and consumes valuable space. Because only single copies of radiological examinations exist, they are prone to being lost or misplaced, thereby consuming additional valuable time and expense. In this paper, mini-PACS for image archiving, transmission, and viewing offers a solution to these problems. Proposed mini-PACS consists of mainly four parts such as web module, client-server module, internal module, acquisition module. In addition, mini-PACS system includes DICOM converter that non-DICOM file format converts standard file format. In client-server module case, proposed system is combined both SCU (service class user: client) part and SCP(service class provider: sewer)part therefore this system provides the high resolution image processing techniques based on windows platform. Because general PACS system is too expensive for medium and small hospitals to install and operate the full-PACS. Also, we constructed web module for database connection through the WWW.

This study was performed to investigate the effect of change of body posture on the rest position and the rotational torque movement of the mandible. Thirty dental students without any signs and symptoms of temporomandibular disorders and with natural dentition were selected for this study. Cervical inclination and the amount of the mandibular movement on protrusion, on left and right excursion, and on tapping in three body postures such as sitting position, supine position without pillow, and supine position with pillow were measured by goniometer, Cervical-Range-of-$Motion^{(R)}$, and mandibular tracking device, $BioEGN^{(R)}$ with $Rotate!^{(R)}$ program. The data obtained were classified and processed according to body posture and type of lateral guidance with SPSS windows program and the results were as follows: 1. There was significant difference among the three cervical inclinations by body postures. 2. Comparison of mandibular rest positions among body postures showed significant difference only for lateral distance in frontal plane, but comparison between before and after swallowing showed significant difference except for the lateral distance, vice versa. 3. Distance and amount of the rotational torque movement on protrusion and/or lateral excursions didn't show any difference by body posture. But by both body posture and lateral guidance type, there were slightly significant difference for some items. 4. A significant difference was shown for the rotational torque movement in frontal plane on tapping by body postures, for the lateral distance in frontal plane on sitting position by lateral guidance type, and for the rotational torque movement in frontal plane by both body posture and lateral guidance type.

This study was performed to investigate the average anthropometric value of normal Korean men and women and to compare the preceding literatures. Additionally, average Korean profilogram was made to serve as a template for diagnosis of facial form. Eighty five Korean subjects(41 men, 44 women) aged between 21 to 26 were selected by members of the author's department on the basis of intact dentition and Class I occlusion without facial asymmetry. Frontal and lateral photographs were taken under standardized condition with digital camera. The image was magnified and adjusted according to the FH plane of cephalometric radiographs and digitized using personal computer. To compare the Western beauty, 25 esthetically pleasing female was selected to measure various angle and distance of the face. 1. It was possible to calculate the mean coordinate value of Korean normal samples which enables the direct visualization and comparison with the use of template. The method in this study was easy to applicate under the Microsoft $Windows^{(R)}$ bases. 2. Maxillary vertical hypoplasia, upper and lower lip protrusion was characteristics of Korean norms and relatively narrow alar base distance, less conspicuous nasal projection was observed. As the vermilion exposure and upper lip length was more than western norm, chin looks shorter than western. To compare the Korean and Western esthetically pleasing profile, facial convexity and nose was less conspicuous in Korean women.

The purpose of this study is to examine the design characteristic about the public space of privately-built apartment housing after the enforcement of price deregulation in Daegu. The public space of the multi-family housing is monotonous and closed according to the position of an elevator and a stair hall by the 1990's. However, the housing has been gentrified since 2000 because of demands of residents and purpose for selling in lots. Thus, the recognition of the apartments has changed and this change has led to extend the living territory and magnify the role of the public space where help interact with neighbors. This study is based on the survey of thirty nine apartment complex. Also, by using an analysis derived from a precedent study, design elements in approach and interior space of apartment residents are comprehended. The characteristic of the porch is researched and divided according to a roof of porch, form as the door, material of roof, wall, the ceiling and floor. Interior space is analyzed by several elements; forms of core, forms, materials and lights of ceiling, materials of walls and floors, existence and nonexistence of windows, and extra interior components etc. As a result of the study, After the enforcement of price deregulation, the public space of apartments has had improved quality in materials and design and the community center for residents such as waiting rooms and spots facilities has appeared. However, the traffic line of interior space has been very intricate. Also, sports facilities and waiting areas are limited to some apartments.

In this study, we quantitatively compare the cooling effects of single span plastic greenhouses by opening or shutting of toot and side vents, and operation of fan or sprinkler. With those variables, we simultaneously made experiments at 4 greenhouses under equivalent conditions. By the experiments, the shutting of roof and side vents caused the high temperature difference of indoor and outdoor which the crops cannot be cultivated. However, the opening of the windows effectively reduced the indoor temperature and showed uniform temperature distribution in the greenhouses. The sprinkler abruptly reduced the indoor temperature, and showed excellent cooling effects. Finally, this paper provides the fundamental data for environmental control in greenhouses.

Among the factors of living environment, the one that is the most closely related with our living is the building. It is one of the biggest reasons for energy consumption as it forms 36% of the total energy consumption. Technologies equipped with excellent energy performance can hardly be applied to rural areas that are relatively poorer. Still, 89.8% rural residents are living in detached houses, and backward houses increase their financial burden and result in reduced insulation performance. Accordingly, this study is going to review the latest research written after 2000 dealing with rural houses and their insulation. The purpose of this study is to analyze the factors of insulation and how to improve insulation performance, conduct field research to find out how to apply low energy technologies applicable to houses with the subjects of experimental houses, the passive houses located in Jecheon City, Hongcheon Saldun zero energy houses, and energy independence villages, and find out how to perform follow-up research on insulation for rural houses. According to the findings, the latest research on insulation for rural houses is mostly focused on walls as well as windows and doors. Also, as ways to improve insulation performance, it suggests us to use high performance insulators, introduce new regeneration energy technology, and secure hermeticity. In addition, through field research, this author could find out low energy technologies applicable to houses such as solar energy facilities and heat recovery systems. Advanced research on insulation for rural houses has been focused on how to use materials or new regeneration energy, so follow-up research will have to consider the types of farming area or the residents' mode of living.

Objective: The purpose of this study was to identify differences in measurement methods for blood pressure (Direct measurement, HP automatic indirect measurement, and SE 7000 Korean made indirect measurement), and to evaluate the clinical trial of the Korean made automatic indirect blood pressure measurement. Material & Methods: From June, 1999 to February, 2000, fifty five consecutive patients were randomized into hypertension group (n=20), normotension group (n=20), and hypotension group (n= 15). Measuring blood pressure by indirect methods (HP NIBP M 1008B and SE 7000 NIBP Korean made) was done simultaneously in the same arm with arterial line for direct blood pressure measurement (HP M1006A). The procedures were repeated ten times at intervals of 2 minutes. Statistical analysis was Performed using SPSS (version 8.0 for windows) software package. Values were expressed as means and standard deviation and means were compared using t-test. Statistical significance was considered present with a p value less than 0.05. Results: In the hypertension group and noromotension group, the disparity between HP direct measurement and indirect SE 7000 NIBP did not show any differences compared to the disparity between HP direct measurement and indirect HP NIBP. In the hypotension group, the disparity in the diastolic pressure between HP direct measurement and indirect SE 7000 NIBP was significantly different compared to the disparity between HP direct measurement and indirect HP NIBP (p<0.001), however, disparities in systolic pressure did not showed any differences. Conclusion: Direct blood pressure measurement (HP M1006A) can be replaced with indirect blood pressure measurements (HP NIBP M 1008B & SE 7000 NIBP) in normotension and hypertension patients. Korean made indirect measurement was found to be more accurate compared to HP indirect measurement in hypotension Patients, but more study is needed.
