To propose the architectural layout for the big general hospital in the face of public health emergencies, we analyzed the conditions, methods, problems and countermeasures for the reconstruction of the isolation ward from the existing medical building layout of a general hospital. The affected areas met the requirements of isolation ward in the reconstruction, and realized the corresponding partition and separation of people. But the cost of occupying the medical room should be concerned. General hospital should be alerted to potential risks of public health emergencies. The characteristics of different construction types, defects, and the function of the hospital should be considered in the construction, rebuilding, and expansion of the hospital, which shouldnot only meet the needs of the development of the hospital daily usage but also consider dealing with emergent public health events. We can adopt the reasonable layout, including setting up a firewall-like device between the channel and the floor, an ordinary ward at ordinary times, and an independent space for emergency by pulling down the gate. This strategy can not only avoid the problem of low utilization rate of the space occupied by the corresponding area in the ward for diseases spread by air and droplets, maximizing the efficiency of the medical site, but also avoid the problem of emergency response to the temporary reconstruction.

PURPOSE: Candida albicans is an opportunistic pathogen that is commonly found in human microflora. Biofilm formation (BF) is known as a major virulence factor of C. albicans. The aim of this study was to examine the influence of bacterial presence on biofilm formation of C. albicans. MATERIALS AND METHODS: The BF of Candida was investigated when it was co-cultured with C. albicans (C. albicans 53, a yeast with a low BF ability, and C. albicans 163, a yeast with high BF ability) and bacteria. BF was assessed with XTT reduction assay. A scanning electron microscope was used to determine the structure of the biofilm, and real-time reverse transcriptase polymerase chain reaction was used to amplify and quantify hyphae-associated genes. RESULTS: Co-culturing with two different types of bacteria increased the BF value. Co-culturing with C. albicans 53 and 163 also increased the BF value compared to the value that was obtained when the C. albicans was cultured individually. However, co-culturing with bacteria decreased the BF value of C. albicans, and the BF of C. albicans 163 was markedly inhibited. The expression of adherence and morphology transition related genes were significantly inhibited by co-culturing with live bacteria. CONCLUSION: Bacteria have a negative effect on the formation of biofilm by C. albicans. This mechanism is the result of the suppression of genes associated with the hyphae transition of C. albicans, and bacteria particles physically affected the biofilm architecture and biofilm formation.

This study aimed to suggest a 1300 scale of a middle school foodservice facility floor plan which was compliant to the principle of HACCP, as well as ensuring food and work safety, and the flow of personnel and food materials. which consisted of 46 nutrition teachers and 6 experts, responded with a questionnaire on the relationship of functional area and space. Using their opinions, key principles for the design of the facility were single direction movement of food materials, customers and workers; minimization of the cross-contamination through the separation of functional space; and securement of customer-focused efficiency; staff-centered convenience and efficiency; and work and food safety. After the completion of an adjacency diagram, bubble diagram and program statement, the functional areas of a 1300 scale middle school food-service facility were allocated as follows: 9.9 m2 for the receiving area, 56.1 m2 for the pre-preparation area, 10.5 m2 for the food storage area, 6.0 m2 for the supplies storage area, 97.8 m2 for the cooking area, 33.6 m2 for the service area, 52.5 m2 for dish washing area, cafeteria 410.5 m2, 4.5 m2 for the front room, for a total of 725.8 m2. Expert groups have pointed to limitations within this model as there are no windows in the office for the influx of fresh outside air and a need for the straight line installation of steam-jacket and frying kettles on the sides of windows. This study can be useful as the guidelines for estimating the investment cost of the facility and placing the placement of functional areas and equipment in the renovation of the facility. It can be also useful data for a methodology of foodservice facility design.

OBJECTIVETo identify valid measures for preventing outbreaks of severe acute respiratory syndrome (SARS) among protected healthcare workers in isolation units.

METHODSArchitectural factors, admitted SARS cases and infection of healthcare workers in different isolation wards between January 30 and March 30, 2003 were analyzed.

RESULTSFour types of isolation wards were analyzed, including the ward where the thirty-first bed was located on the twelfth floor, the laminar flow ward in the Intensive Care Unit where the tenth bed was located on the fifteenth floor, the ward where the twenty-seventh bed was located on the thirteenth floor of the Lingnan Building, and thirty wards on the fourteenth to eighteenth floors of the Zhongshan Building. The ratios (m(2)/m(3)) of the area of the ventilation windows to the volume of the rooms were 0, 0, 1:95 and 1:40, respectively. Numbers of SARS cases in the wards mentioned above were 1, 1, 1 and 96, respectively. Total times of hospitalization were 43, 168, 110 and 1272 hours, respectively. The infection rates of the healthcare workers in the areas mentioned above were 73.2%, 32.1%, 27.5% and 1.7%, respectively. The difference in the infection rates was of statistical significance.

CONCLUSIONSIsolating SARS cases in wards with good ventilation could reduce the viral load of the ward and might be the key to preventing outbreaks of SARS among healthcare workers along with strict personal protection measures in isolation units.

architecture in the condyle in the control and experimental groups. 4. In histologic findings of condyles, there were thicker fiberous and proliferative layers in experimental group than those of control group until 2 weeks after distraction with compression force. But, no differences were seen between two groups on 3, 4, 7 weeks after compression. 5. In histologic findings of disc, more collagen contents in extracellular matrix, more regular fiber bundles, and less elastin fibers were seen in experimental group than control group until 2 weeks after distraction with compression. But, no differences were seen between two groups on 3, 4, 7 weeks after distraction with compression. From this study, we could identify that the new distraction osteogenesis technique with compression stimulation might improve the quality of bone regeneration. The no remarkable differences on TMJ response between control and experimental groups were seen and TMJ tissues were recovered similarly to normal TMJ condition after 3 weeks. These results appeared the DO technique might be a new tool with a few advantages for DO application.]]>

Brian Allgood Army Community Hospital (BAACH) is one of the US military General Hospitals in Korea that have blood services. The author of this paper is a civilian employee who has been working in the blood bank for 37 years. Through this experience, a difference between BAACH and the Korean Medical Center has been observed. First, BAACH performs a blood culture for the sterility test upon the receipt of platelets from the Korean Red Cross, and measures the pH at the end of allowable storage. Second, some military facilities use the Frozen Blood Program as the storage/thawing system of Deglycerolized Red Blood Cells (DRBC) and the use of DRBC. Third, most military facilities have a continuous training education program for those working in the blood bank provided by the Armed Service Blood Program.

We report here on a case of genetically confirmed type Ia glycogen storage disease (GSD) that was diagnosed in the military hospital. A twenty-year old soldier was admitted to the hospital with abdominal fullness. He had a past medical history of hepatomegaly that was firstly recognized at six months after birth, and he had been followed-up at an outpatient clinic with the presumptive diagnosis of type III GSD. He also had a history of growth hormone therapy because of growth retardation. However, he arbitrarily refused medical observation from 14 years of age. On the physical examination, the height of the patient was 163.1 cm and significant hepatomegaly was observed. Significantly abnormal liver-associated paramters were observed on the laboratory findings and multiple hepatic adenomas were observed on the CT exam and MRI scan. To determine the proper treatment, we tried to confirm the exact type of GSD in the patient. By mutational analysis, we found the c.648G>T homozygote splicing mutation in the G6PC gene and the patient was confirmed as having the type Ia GSD.

OBJECTIVETo study the main factors affecting sound-insulation effects of control rooms in workshops with noise, so as to improve the protection.

METHODSThe sound-insulation effects of 467 control rooms were determined, and different building materials, structures of door and window, airtight states etc. were analyzed.

RESULTSThe affecting factors contributed to the sound-insulation effects (Eta(2)) were in the order: airtight states (0.168), building materials (0.080), structures of window and door (0.030, 0.029), sound pressure levels and frequency spectrum's characteristics (0.008, 0.006). Under airtight state, the sound-insulation effects of different building materials of the rooms were as follows: double bricks [(19.6 +/- 3.5) dB(A)]; single brick [(15.4 +/- 3.4) dB(A)]; plank [(13.1 +/- 1.6) dB(A)] or aluminum alloy plate with glass [(13.4 +/- 2.5) dB(A)] (P < 0.01). Of 4 group rooms, with the same structure of doors but double or single bricks of windows. 3 groups with dormant window had higher sound-insulation effects [(15.9 +/- 2.8), (18.7 +/- 3.6), (19.3 +/- 2.5) dB(A)] than those with casement window [(14.1 +/- 2.4), (14.9 +/- 2.3), (16.5 +/- 2.4) dB(A)] (P < 0.01 or P < 0.05); 2 groups with dehydrated window [(18.7 +/- 3.3), (22.6 +/- 3.8) dB(A)] higher than those with dormant window [(15.9 +/- 2.8), (19.9 +/- 3.0) dB(A)] (P < 0.05). Of 6 group rooms, with the same structure of windows but double or single bricks of doors, only in 1 group with double-layer door had higher sound-insulation effect [(18.7 +/- 3.6) dB(A)] than that with single-layer door [(15.9 +/- 2.8) dB(A)] (P < 0.01).

CONCLUSIONThe control room should be designed rationally, kept airtight, according to the sound pressure levels and the condition of the workshop.
