  • This paper is concerned with the development and application of a stochastic model for daily sulphur dioxide $(SO_2)$ concentrations in urban area (Seoul). For this, the characteristics of the regression trend, periodicity and dependence of the daily $SO_2$ concentration are investigated by a statistisical analysis of the daily average $SO_2$ values measured in Seoul area during 1989 $\sim$ 1990. Based on these, nonlinear regression time series model for the prediction of daily $SO_2$ concentrations is derived. A statistical procedure for using the model to predict the concentration level is also proposed.

  • This study aims to examine the actual status of the urban heat island in Daegu by analyzing the data of 17 automatic weather stations installed in the Daegu area. And the results can be summarized as follows: First, regarding the temperature distribution in Daegu by summer time zones, for the 31 days(August 1st till 31st), 18 days showed daily maximum temperature over $30^{\circ}C$, and 11 days indicated daily minimum temperature over $25^{\circ}C$. The day that showed the highest daily maximum temperature was August 5th, which indicated $36^{\circ}C$. Second, about the spatial distribution of time ratio exceeding $30^{\circ}C$ and $25^{\circ}C$, the area with the highest time ratio exceeding $30^{\circ}C$ is mostly the downtown(central area), eastern area, and northern area. Meanwhile, regarding the time ratio exceeding $25^{\circ}C$, the downtown area centering around the central area were high as over 70%, and the outskirts were low as under 65%. Third, considering the temporal distribution of daily maximum temperature and daily minimum temperature, daily maximum temperature was shown around 14:00 to 15:00 while the daily minimum temperature was indicated around 17:00 to 18:00. Daily maximum and minimum temperature were appeared at northeast and downtown, respectively. Fourth, regarding the spatial distribution of tropical days and tropical night days, tropical days showed 77% and tropical night days indicated 42% before and after the 24th and also the 13th each. Tropical days were occurred up to 24 days at northeastern area. And the southwestern area of Daegu showed under 22 days. The downtown showed the 14 days of the tropical night. However, the outskirts indicated relatively few days as under 10 days. Fifth, about the spatial distribution of the average daily temperature range (the difference between the highest temperature and lowest temperature), the central area, the central part of the city, showed the smallest as $7.2^{\circ}C$, and as it was closer to the northern area, it became larger, so in the eastern and northern area, it was over $8.8^{\circ}C$ or so.

  • The purpose of this study was to assess the energy expenditure and investigate the relationship between related variables in 70 female university students. Resting energy expenditure estimated by Harris-Benedict formula, WHO/NAO/FAO formula and various formulas based on body weight and body surface area were 1366.9$\pm$74.4kcal/day, 1287.8$\pm$106.6kcal/day, 1171.4$\pm$155.8kcal/day and 1342.0$\pm$97.4kcal/day. Measured resting energy expenditure by indirect calorimetry(Model : Metavine and TrueOne2400) were 1582.0$\pm$150.1kcal/day and 1268.2$\pm$152.9kcal/day, respectively. Average step number per day was 11981.2$\pm$3014.4 steps and average step number per hour was 746.1$\pm$198.0 steps/hr. Daily energy expenditure by using Harris-Benedict formula, body weight formula, body surface area formula, WHO/NAO.FAO formula and 15-min check list formula were 2374.7$\pm$249.6kcal, 2033.5$\pm$313.2kcal, 2331.2$\pm$266.0kcal, 2240.8$\pm$185.5kcal and 2195.5$\pm$398.3kcal. Meanwhile energy intake of subjects was 1714.9$\pm$551.2 kcal. Daily energy expenditure has positive correlation(r=0.262) with daily step number. And there was significant positive correlations(r=0.35-0.68) between various daily energy expenditures and muscle mass. These results suggested that increase of daily step number by using pedometer is good method to increase daily energy expenditure. In particular, increase in step number can reinforce the amounts of muscle.

  • This study was performed to examine the effects of daily commodities on student's scientific knowledges, inquiring abilities and attitude toward science in elementary school science classes. Daily commodities were collected and sorted properly so as to be readily utilized as experimental instruments in science classes. 164 students of elementary school 5th grade in Taejon City were selected for the study and they were evenly divided into two different groups, one for experiment and the other for comparation respectively. In every science classes throughout the school semester, the experimental group was supplied with daily commodities in addition to conventional instruments while the controlled group for comparation was supplied only with conventional instruments. Student's responses to the questionnaire were treated by statistical analysis and for that purpose the computer programme of SPSS WIN(6.0) was employed. The results of the study are as follows; 1. There is no expressive disparity appeared in the increments of scientific knowledge between experimental and controlled (comparing) groups. 2. The disparity of increments in inquiring ability between experimental and controlled groups is fairly expressive (P<0.05). The experimental group with daily commodities in science classes attained 5% more in increment of inquiring ability than the controlled group. 3. The disparity of the changes in student's attitudes toward science between two groups is remarkable (P<0.001). Student's attitude toward science was much more improved in experimental group than controlled group. The difference in improvement rate between two groups is 8%. The facts mentioned above make it evident that in elementary school science course daily commodities are very effective to enhance student's positiveness as far as both inquiring ability and attitude toward science are concerned. In this respect, a lot of efforts are expected to be made in searching and supplying further the proper daily commodities for elementary science courses. In addition, it is also called for that the examples of replacing conventional instruments with daily commodities will be introduced in future editions of elementary school science book and its guide book if possible.

  • As construction projects are getting more complex and larger in size, the amount of information is increased exponentially, which requires information management systems to accumulate as-built information throughout the project life-cycle. Particularly, a daily report system is very important, since it helps them keep track of various as-built information at the most detailed level. However, there have been many problems with daily reporting since its process is time-consuming and contains a lot of redundancies and ambiguities. Therefore, the objective of this research is to improve a process of collecting as-built information and managing daily report. To do so, this research developed a to-be process model and a daily report system. The daily report system developed in this research consists of interactive task generator and daily report management modules. The system has been successfully implemented in a real world construction project. The system development processes including process analysis, information models and system features are described along with discussions on the results and improvements.

  • A study has been performed to estimate the average and high (90th percentile of consumers-only) daily intakes of sorbates by age-sex groups (> 3 years old) in Korea. The estimation of daily intakes was based on individual-based dietary intake data in ‘National Health and Nutrition Survey in 1998’and the contents of sorbates from samples. The estimated daily intakes (EDI) of sorbates for average consumers ranged from 0.09 mg/kg/bw/day to 0.51 mg/kg bw/day corresponding to 0.4-2.1% of acceptable daily intake (ADI). For high consumers, the range of EDI of sorbates was 3.42-14.65 mg/kg bw/day corresponding to 13.7-58.6% of ADI. Foods that contributed most to the daily intakes of sorbates for all age-sex groups were processed fish products, processed meat products, and salted floods. There was an inverse relationship between age and the consumption of sorbates for average and high consumers, whereas no marked pattern was emerged by sex categories. The intake levels of sorbates even among high consumers were below the ADI in Korea.

  • The purpose of this study is to clarify the correlation between the degree of patients daily activities and that of a sense and social support of families. This study covers families of 252 patients under home health nursing care at 6 University Hospitals during the period of March to May. 1999. The data were collected by using three different questionnaires. Data were analysed by utilizing SAS program such as frequency. average. percentage. t-test. ANOVA. Scheffe test and Pearson Correlation Coefficient. The results were as follows: 1. The average score of patients' daily living activity was $2.36\pm0.67$. $97.2\%$ patients turned out to be. in part. dependent on their family's care. $66.5\%$ of the patients were still dependent on their families in walking: $66.3\%$ In bathing: and $61.0\%$ in using toilet. 2. The average score burdened family caregivers had felt was 2.25 in 4 full point which can be interpreted as average. Among the six burden dimensions. time was said to be the No. 1 burden-yielding factor. When it comes to the characteristics of patients. there were tendencies for patients with lower incomes residing in communal housing. with cerebrovasculal diseases and with higher score of daily living activity to show a higher burden scores. 3. The average score of social support was 2.49 in 5 point. which represents a average score. Among other items. the opportunity of social integration was 2.66. topping the list whereas a chance of upbringing was starkly low at 2.42. The higher scores of social support were shown in cases where the caregiver was male spouse. total care giving duration exceeded 25 months and malignant patients daily living activity scores were low. 4. The score of patients daily activity was positively correlated to the degree of the family burden (r=0.1942). Data indicates there was direct correlation between daily living activity and burden of time consuming, self-improving and physical impairment. 5. The score of the patients daily living was negatively correlated to the social support (r=0.3414), As a whole. there was negative correlation between social support and the formation of intimacy and self-confidence.
