Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

The application of a digital technology is becoming more common in architecture and design. It gives to architects the work environment which is free from hour, physical and formative limit. The technology becomes the driving force of creative imagination. As a result, digital architecture quite differs from the existing ones. Space design filed is influenced by the trend. This study, therefore, investigates the application of digital-architectural design methodology for space marketing strategy. The following study results were obtained:1) The classified application patterns of digital technology methodologies for architectural design. 2) The availability of the application patterns for commercial space design. 3) The value of the application patterns for space marketing as a strategy methods.

High-speed/low-power/low-cost multipliers play an important role in micro-processors and digital signal processors because multiplier core not only occupies a signigicant percentage of the silicon area, but also limits the overall performance. This paper describes a design of dual mode multiplier (DMM) that performs single- and double-precision multiplications using hardware required for single-precision multiplication. We propose an efficient algorithm which partitions a double-precision multiplication into four single-precision sub-multiplications and then computes them with sequential accumulations. When compared with conventional double-precision multipliers, our approach reduces hardware complexity required for double-precision multiplication by about one third at the expense of increased latency. The DMM has been designed using a 0.25-㎛ 5-metal CMOS technology, and contains about 25,000 transistors on the area of about 0.77×0.40㎟. The HSPICE simulation results show that the DMM core can safely operate with 150-MHz clock at 2.5-V, and the estimated power dissipation is about 110-mW at double-precision mode.

Allergic rhinitis is characterized by rhinorrhea, sneezing and nasal obstruction. Allergic rhinitis increases because of developments of diagnostic techniqhe, environmental change, especially industrialization. Recently people have studied on allergic rhinitis. We studied 107 allergic rhinitis patients with SBJ from June. 2002 to December, 2002. There was a significant effect of SBJ on allergic rhinitis. So, we suggested the clinical effect of SBJ on allergic rhinitis.

Every interventional procedure can result in infectious complication even though its incidence is very low. Increases in both indication of procedures and number of immunocompromised patients are likely to result in increase of infectious complications. However, no randomized controlled trials to evaluate the effectiveness of prophylactic antibiotics in interventional procedures have ever been performed. This study was performed to investigate the actual pattern of practice and awareness of medical providers concerning the antibiotic prophylaxis following vascular and nonvascular interventional procedures. A questionnaire regarding prophylactic antibiotic usage was sent to the interventional radiologists in 40 hospitals. A total of 12.2-30.3% responders used prophylactic antibiotics for vascular procedure. More than 80-90% of responders answered that vascular procedures except catheter insertion, are not clear indications of prophylactic antibiotics, In contrast, 31.3% and 51.5% of responders used prophylactic antibiotics for genitourinary and biliary drainage respectively. About 60-70% of responders considered both genitourinary and biliary drainage as clear indications of antibiotic prophylaxis. Further study assessing the appropriate antibiotic usage in interventional procedures is warranted.

We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP, The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-l0,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

Purpose : The purpose of this study was to identify the physical health status and health behavior practice of in-home elderly in order to provide basic data for effective nursing intervention to promote health and quality of life. Method : The subjects for this study were 299 elderly persons in the D city. Data were collected by interview with questionnaires. Result : The ratio of chronic disease was higher for the elderly who live alone than the elderly who live with family. Arthritis was the most common chronic disease of the elderly in spite of the fact that either they live alone or live with family. The physical health status score of the elderly who live with family was statistically higher than the elderly who live alone. The health behavior score of the elderly who live with family was statistically higher than the elderly who live alone. Conclusion : To promote health behavior of the elderly, it is necessary to develop nursing intervention that considers sociocultural tradition and demographic character.
