  • In this research, regarding the type three blast furnace slag (BS) regulated by KS F 2563 and supplied to actual ready mixed concrete plant, the fineness on specification and actually measured fineness by Blain test were compared, and by applying the hydrometer method used for early prediction of concrete strength, the feasibility of the hydrometer method for acquisition inspection of BS was analyzed. Additionally, the influence of various fineness of BS on properties of cement mortar was also assessed. According to the experimental results of this research, correlation of fineness values between specification and actually measured data were not matched. In the case of the rapid evaluation method using hydrometer, a good relation was shown between the fineness data obtained from hydrometer and Blain test. furthermore, from the cement mortar properties test, there was a good relation was obtained between fineness data from rapid evaluation method by hydrometer and cement mortar properties, while there was no clear relation between fineness data from specification and cement mortar properties. Hence, as a qulity controlling method of BS fineness, a rapid evaluation method using hydrometer is suggested as a new method.

  • A quadrilateral-triangular mixed grid method for the solution of incompressible viscous flow is presented. The solution domain near the body surface is meshed using elliptic grid geneator to acculately simulate the viscous flow. On the other hand, we used unstructured triangular grid system generated by advancing front technique of a simple automatic grid generation algorithm in the rest of the computational domain. The present method thus is capable of not only handling complex geometries but providing accurate solutions near body surface. The numerical technique adopted here is PISO type finite element method which was developed by the present author. Investigations have been made of two-dimensional unsteady flow of Re=550 past a circular cylinder. In the case of use of the unstructured grid only, there exists a considerable amount of difference with the existing results in drag coefficient and vorticity at the cylinder surface; this may be because of the lack of the grid clustering to the surface that is a inevitable requirement to resolve the viscous flow. However, numerical results on the mixed grid show good agreements with the earlier computations and experimental data.

  • The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each part. It requires various functions to get the income and activities. But city has a limitation of a available land to provide the required function and a sufficient space to supply the activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation between the public and private space and the building shape to provide the design information according to the development constraints such as land area, functional limitation, accessibility, etc. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US.

  • The purpose of this study was to investigate the consumption and perception on the effect of cooked rice mixed with multi-grain (CR-MG). Reason for like and dislike, intake frequency and variables related with the satisfaction of CR-MG were also investigated. The data for the analysis was collected from 315 adults who were residing at Seoul${\cdot}$Kyeonggi and Kangwon area and analyzed by the SPSS 11.0 program. The result showed that 84.8% of the respondents consumed CR-MG, showing significant difference by gender and occupation (p<0.05). It also revealed that they consumed it knowing their effect, showing significant difference by all general characteristics except for resident area and BMI, respectively. Kind of multi-grain (MG) mixed with cooked rice was high in the order of SoRiTae (80.1%) > brown rice (73.4%) > black rice (72.7%) > waxy rice (61.0%), respectively. As for the mixing type of MG, 61.4% of the respondents preferred non-mixed product rather than pre-mixed product. 2 or 3 kinds were preferred numbers of MG mixed with rice, showing significant difference by age (p<0.001) and marital status(p<0.05), respectively. 59.9% of the respondents answered 'high nutritive value more than polished rice' as the major reason for like, whereas 31.3% answered 'greatly rough more than polished rice' as that for dislike, respectively. By the use of multiple regression analysis, it revealed that health was the most significant variable which affect the satisfaction of CR-MG. From these results, it was suggested that in view of the high consumption and intention to continue the intake of CR-MG, following studies should be conducted to improve the preference of CR-MG.

  • This paper presents the investigation results on the classification of the university campuses. For the classification, we selected the spatial index as the evaluation indicator since the environmental factors and maintenance methods vary from university campus to university campus. For the study, we used eight spatial indices of the 30 national universities. This paper provides the spatial characteristics of different campus types, presents campus classification analysis as a future research approach to campus maintenance, and provides the data for the future study of comparison among universities. The results are as follows. 1) The classification investigation categorized the university campuses into three groups. Type 1 is a large-scale type, located near downtown. Type 2 is a medium-scale type, located at a remote site from downtown. Type 3 is a small-scale type, which is located comparatively near downtown. 2) Type 1 is a large-scale mixed area type, and 13 universities belong to this group. Type 2 is a medium-scale suburban area type, and six universities are in this group. Finally, Type 3 is a small-scale downtown area type, and 11 universities belong to this group.

  • In this study, visible and near infrared channels of NOAA/AVHRR data were used to classify land use and vegetation types over Korean peninsula. Analyzing forest stand structures and prediction of forest productivity using satellite data were also reviewed. Land use and land cover classification was made by unsupervised clustering methods. After monthly Normalized Difference Vegetation Index (NDVI) composite images were derived from April to November 1998, the derived composite images were used as temporal feature vector's in this clustering analysis. Visually interpreted, the classification result was satisfactory in overall for it matched well with the general land cover patterns. But subclassification of forests into coniferous, deciduous, and mixed forests were much confused due to the effects of low ground resolution of AVHRR data and without defined classification scheme. To investigate into the forest stand structures, digital forest type maps were used as an ancillary data. Forest type maps, which were compiled and digitalized by Forestry Research Institute, were registered to AVHRR image coordinates. Two data sets were compared and percent forest cover over whole region was estimated by multiple regression analysis. Using this method, other forest stand structure characteristics within the primary data pixels are expected to be extracted and estimated.

  • Purpose: The purpose of this study is to identify factors affecting the urinary incontinence (UI) prevalence and the quality of life among elderly adult women who are subject to home visiting healthcare services. Methods: A cross-sectional study was conducted with 400 women aged 60 or over who were registered for home health care services at one health center in Gangwon-do. Data were collected using a structured questionnaire consisting of UI severity, UI type, and the quality of life. The UI severity was assessed using International Consultation of Incontinence Questionnaire-Short Form (ICIQ-SF), the quality of life using Incontinence Quality of Life (I-QOL), and type of UI using Questionnaire for Urinary Incontinence Diagnosis (QUID). The data were analyzed by using x2 test, independent t-test, one-way ANOVA, Pearson's Correlation, binary logistic, and multiple lineal regression. Results: The prevalence of UI is 51.7%. The mean score of ICIQ-SF was 9.70±4.04 for women with UI and 0.04±0.51 for women without UI (t=-33.67, p<.001). As the frequency of day time urination (OR=1.34), the subjective health status (OR=1.45), and the educational status (OR=0.90) were higher, the risk of UI prevalence was the higher. The factors affecting I-QOL were ICIQ-SF score, mixed UI, subjective health status, and nighttime urination (adjusted R2=.61). Conclusion: The results of this study showed that UI severity, mixed UI, subjective health status, and day time urination affected the quality of life. It suggests that the assessment for the severity and type of UI be needed to prevent UI or improve the quality of life of UI vulnerable elderly adult women.
