The current trend of If (Information Technology) in 21st century demands management innovation, that is Business Process Reengineering (BPR) in all the industry including construction project. The solution of its demand is proposed by IT based on Internet. And also, in order to meet this objective, from 1997 domestic construction industry is accelerating to systematize CALS (Continuous Acquisition and Life-cycle Support) which is being planned to apply by government. These efforts give much weight to build computer systems rather than to improve and redesign construction business process that is more important for system application. This research develops a model for applying the BPR to construction industry, especially construction site that is a base to build a system for CALS. And the research suggests performing method, process and modeling technique of BPR to be applicable in business process redesign of construction field. Also, focusing on the research of execution step of business in construction site will be helpful for the site worker to perform BPR in construction site.

Generally, a street-inlet in road facility is aimed to exclude rainfall and filth from sewer system. In order to solve some problems in current street inlet facilities, some revised inlet systems have been suggested. Those revised facilities can also solve an environmental problem like a bad smell emitting from the worn facility and solve civil petitions due to its safety and poor quality of passing rainfall. In this study, the existing rainfall exclusion facility was investigated including foreign countries and a developed street inlet model was represented through estimating of their structures, characteristics and costs. It also be analyzed that the existing problems can be solved by a trial construction and the developed model was compared with existing models by focusing on constructability and maintenance capacity.

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.

Recently, our construction industry is using various work sections classification systems for civil engineering projects. However, because the public IDB(Integrated DataBase) for the work sections is insufficiently built, it is difficult to connect construction operation information from construction site to standard specification or standard method of measurment. Therefore, this study suggests a methodology to link the construction work sections information, such as cost, schedule, drawings and specification, with civil engineering standard method of measurement. And the methodology suggested in this study was applied to a web-based work sections information management system with IDB. An IDB modeling was designed by using DFD (Data Flow Diagram) and ERD (Entity Relationship Diagram).

To investigate the food preservative effects of leaf mustard Dolsan(Brassica juncea), the pretreated extract of leaf mustard Dolsan were added to Kimchi and the results are as following, pH of Kimchi added leaf mustard Dolsan extracts were lower than that of control at initial stage, but after 6 days of fermentation, pH was higher in order of Kimchi added the pretreated extract of leaf mustard Dolsan(hydrolyzed at 30℃ for 24 hours, PEM), the unpretreated extract of leaf mustard Dolsan(UEM) and control. The total number of bacteria and lactic acid bacteria increased rapidly at the initial stage of fermentation and reached plateau at 2 days of fermentation. The number of bacteria and lactic acid bacteria, of Kimchi added leaf mustard Dolsan extracts were lower than that of control, and antimicrobial activity of PEM in Kimchi was higher than that of UEM. After 2 days fermentation, sensery value of Kimchi added PEM was more excellent than that of control.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

This study was conducted to investigate the effect of breed, sex, year of birth, month of birth, litter size and parity of sow on certain postweaning traits in swine. The data for this study were obtained from 5,386 heads of Duroc, Landrace and Yorkshire boars and gilts tested at a swine breeding farm in Icheon, Kyunggi-Do from August, 1982 to August, 1987. The results obtained in this study are as follow: 1. The least-squares overall means of the traits studied were 0.777±0.002㎏ for average daily gain, 158.7±0.28 days for age at 90㎏, 1.833±0.008㎝ for backfat thickness, 112.2±0.13㎝ for body length and 63.7±0.05㎝ for wither's height, respectively. 2. Among the three breeds compared, the Duroc had the highest average daily gain and reached 90㎏ at an earliest age. The Landrace had the thinnest backfat and longest body length. In wither's height the Duroc was the highest. 3. Males had higher average daily gain, reached 90㎏ at an earlier, age, had thinner backfat, longer body length and higher wither's height than females. 4. Year of birth and month of birth had significant effects on all of the postweaning traits studied. The pigs born in June, July and August had comparatively higher average daily gain and earlier age at 90㎏ than those born in other months. The pigs born in October had the thinnest backfat. 5. the effect of litter size was significant for age at 90㎏ and backfat thickness, but was not significant for average daily gain, body length and wither's hight. The pigs in litter sizes of 5 to 7 reached 90㎏ at an earliest age, and those in litter size of 12 or more reached 90㎏ at a latest age. Backfat was thinnest in the litter size of 4 or less and was thickest in the litter size of 12 or more. 6. The pigs in 2nd 3rd parities had the highest average daily gain and reached 90㎏ at an earliest age, and those in 5th parity was the most inferior in the two traits. Backfat was thinnest in the 1st parity and was thickest in the 5th parity.

The computerization is an important factor for scientific construction management. Con-struction management softwares are being widely used for computerizing project control and scheduling. The code systems in those softwares enable various classifications of con-struction information such as filtering, sorting and grouping, and facilitate easy appli-cation of computer system. This study analyzes the code systems of three softwares, which are representatively used in the construction sites, through a comparative analysis for the applicability in construction management. Finally the study suggests a desirable structure of code system and a selection criterion of software to improve the applicability of construction management softwares in the construction sites.
