A standardized construction information classification system is essential for organizing construction CALS and CM. In 1997, Uniclass system was developed for superseding CI/SfB system that was being used as a representative WBS. Uniclass system is organized on the basis of ISO frame and consists of tables for classifying information related to construction management and electronic commerce. This study was implemented for the analysis of applicability of Uniclass system, comparing with CI/SfB system, as a WBS for the construction CALS. This study suggests a alternative table of Uniclass to improve applicability in practical use. Uniclass system was analyzed as the best classification system for the civil engineering project among the existing systems, howewer, the classified items for CM and construction CALS need to be modified with more detailed items.

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.

<P>Tardive dyskinesia (TD) is a hyperkinetic movement disorder associated with the prolonged use of antipsychotic drugs. Since prostate apoptosis response 4 (Par-4) is a key ligand of the dopamine D2 receptor, the Par-4 gene (PAWR) is a good candidate gene to study in the context of TD susceptibility. We examined the association between PAWR gene polymorphisms and TD. Three single nucleotide polymorphisms of PAWR were selected for the analysis: rs7979987, rs4842318, and rs17005769. Two hundred and eighty unrelated Korean schizophrenic patients participated in this study (105 TD and 175 non-TD patients). Genotype/allele-wise and haplotype-wise analyses were performed. There were no significant differences in genotype and allele frequencies between the two groups. Haplotype analysis also did not reveal a difference between the two groups. Within the limitations imposed by the size of the clinical sample, these findings suggest that PAWR gene variants do not significantly contribute to an increased risk of TD.</P>

<P>Abstract </P><P>The main objective of the present study was to determine the relationship between treatment responses of delirium and genetic polymorphisms in the dopamine transporter. The optimal dosages of haloperidol and risperidone in the treatment of delirium were also investigated. Either haloperidol or risperidone was administered to delirium patients, and delirium symptoms were measured daily until remission. Variable number of tandem repeat (VNTR) polymorphisms of the dopamine transporter were determined using the polymerase chain reaction. Among 42 subjects, symptoms of delirium appeared a mean of 9.68 days after hospitalization. A majority of the subjects (83.3%) had the type 10/10 polymorphism. Dosages of haloperidol and risperidone at the day of recovery were 1.67 mg/day (SD = 1.32; range 0.5–2.5 mg/day) and 1.19 mg/day (SD = 1.14; range 0.5–5.0 mg/day), respectively. The mean drug response time was 8.5 days in the haloperidol group and 4.8 days in the risperidone group (no significant difference). The response rates at the 3rd and 7th days after medication did not differ with either the drug group or the dopamine transporter polymorphism. Relatively low doses of risperidone and haloperidol exhibited similar efficacies, and dopamine transporter polymorphisms do not appear to play a major role in the action of antipsychotics on delirium.</P>

While more attention has been paid in recent years to urban point source pollution control, no considerable measures have been taken to control urban non-point source pollution. Contaminants from non-point sources deposited on urban impermeable surfaces such as road and highway are easily released to the public waters by rainfall, leading to the deterioration in water quality in urban area. The present study investigated a system using filter media to reduce the level of contamination in urban road runoff. Three different media, designated as J-P (polypropylene, blowing type), B-P (polypropylene, fiber type), and P-F (Polyvinyl alcohol, cube and sheet type) were evaluated on the basis of pollutant removal efficiency as well as hydraulic property. Experiments were peformed using a 1/4-scale treatment unit at various pollutant roading and rainfall intensity with real rainwater runoff collected from road surfaces. The results at different rainfall intensities shows that the medium J-P is superior to the other media for water permeability. J-P was not blocked at 10 ㎜/hr rainfall and its permeability was stable. On the other hand, B-P and P-F resulted in substantial overflow ratio even at l ㎜/hr rainfall intensity. Comparing treatment efficiencies for suspended solids, all media showed similar removal ranged from 91% to 95%. However, J-P seems to be better than the other media considering its higher water permeability. J-P and P-F, both hydrophobic, yielded over 76% of heavy metal removal. But, the hydrophilic media B-P showed much smaller removal ranging from 26% to 47%. This indicates that J-P and P-F are beneficial to remove heavy metal due to their hydrophobic property. The treatment efficiencies over PAHs (poly aromatic hydrocarbons) showed the similar removal efficiency ranging from 66% to 97% for all three media.

Growth in population and urbanization has progressively increased the loadings of pollutants from non-point sources as well as point sources. Therefore, it is necessary to manage both point and non-point sources contaminations for protecting water environment and improving water quality. This study investigated the characteristics of pollutant release over a wide range of rainfall intensities as a requisite to control road runoff that accounts for the largest portion of non-point source contamination in urban areas. Samples of runoff rainwater collected from real road surfaces were analyzed for physicochemical parameters such as pH, suspended solids, and heavy metals. A experimental model road (30cm×30cm) was also used to evaluate wash-off properties of pollutants deposited on the surface as functions of time and rainfall intensity. Analysis of runoff samples on rain events showed that the pollutant wash-off patterns for heavy metal and suspended solids were similar. This implies that the particles in rainwater adsorb heavy metals. Experiments using the model road made of impervious asphalt demonstrate a strong first flush phenomenon. At high rainfall intensity, approximately 80% of total pollutants were released within 15 min. The pollutant wash-off rates rapidly increase from 9 ㎜/hr to 12 ㎜/hr of rainfall intensity and decrease over 12 ㎜/hr of rainfall intensity.

<P>While more attention has been paid in recent years to urban point source pollution control, no considerable measures have been taken to control urban non-point source pollution. Contaminants from non-point sources deposited on urban impermeable surfaces such as road and highway are easily released to the public waters by rainfall, leading to the deterioration in water quality in urban area. Experiments were performed using a reactor and real rainwater runoff obtained from road surfaces at various pollutant loading and rainfall intensity to determine the criteria for the first flush rainwater and to evaluate the applicability of the reactor for treating road runoff. The results at different rainfall intensities show that the medium PPB is superior to the other media for water permeability. PPB was not blocked at 10 mm/hr rainfall, and its permeability was stable. On the other hand, PVS and PPF resulted in a substantial overflow ratio even at 1 mm/hr rainfall intensity. Comparison of treatment efficiencies for suspended solids showed that all media showed similar removal efficiency ranging from 91% to 95%. However, PPB seems to be better than the other media considering its higher water permeability. PPB and PPF, both hydrophobic, yielded over 76% of heavy metal removal. But the hydrophilic media PVS showed much smaller removal efficiency ranging from 26% to 47%. The treatment efficiencies over PAHs (Poly Aromatic Hydrocarbons) showed the similar removal efficiency ranging from 66% to 97% for all three media. In this study a reactor using filter media was investigated to reduce the level of contamination in urban road runoff.</P>
