For the purpose of finding out the distributions of groundwater uses, the effect of facilities on the parameter and the correlations among measurements, various statistical analysis were carried out with the data of groundwater quality measurements from January to December in 2002. 1. The rates of groundwater for drinking water were 10.5% in Yangcheon-Gu, 10.2% in Kangdong-Gu, and 9.9% in Eunpyung-Gu. The rates of other uses of groundwater were shown to be 58.1%(786 wells) for civil defense emergency, 22.1%(299 wells) for contamination-concerning, 9.8%(133 wells) for water quality monitoring, consisting of 90% of all groundwater. 2. The 52.6% of groundwater for drinking were demonstrated to be appropriate while 91.9% for tither uses-domestic, industrial, agricultural uses- were shown to be proper. 3. For drinking water, the average values of colar, turbidity, NH3-N, F, and Fe were 11.216 degree, 2.138 NTU, 2.458mg/l, 0.212mg/1 and 0.507mg/1 respectively. 4. In cases of drinking water wells for emergency, the results of statistical analysis showed that building year of the wells, depth and pumping rate didn't affect on whether it was proper for that use or not. It were shown that there were linear correlations between depth and NO$_3$-N(-0.171) and F￣(0.332) while the correlation coefficients were 0.381 and -0.169 between the building year of well and depth and pumping rate respectively.

The use of school should not be limited to student education any longer but be extended for attaining social benefits. For this reason, school should play central roles not only in education but also in childcare, welfare, culture, physical education, etc. In order for school to accommodate various new functions, it is essential to promote the mixed-uses of school facilities, and this process requires the involvement of private capitals for early achievement of social benefits from school facilities. Thus, this study purposed to examine the necessity of the multiple uses of school facilities through the investment of private capitals, to diagnose the adequacy of build-transfer-lease (BTL) applied currently to the multiple uses of school facilities, and to find obstacles to the activation of private sector investment and suggest solutions for the obstacles. In particular, this study aimed at proposing plans to enhance the efficiency of private sector investment and activate private sector investment projects by suggesting how to promote the multiple uses of school facilities in consideration of profitability for private investors.

Many plant species are used in Malaysia in folk medicine for the treatment of cancer. This paper presents some of these species with details on other ethnopharmacological uses, the known bioactivities and some chemical constituents of each of the species given. It is normal practice in traditional medicine that one species of plant is used to treat various ailments. Thus the plant species listed are all used to treat cancer but have various other ethnophrmacological uses as well, some with few other uses and rest with many other uses. Information on bioactivities of each species resulting from tests on human and experimental animals are also given. Proven bioactivities give strength to ethnopharmacological claims on the efficacies of plant resources in the treatment of cancer and various other ailments but will but will not necessarily lead to the production of new pharmaceutical drugs. Many of the known chemical constituents of each species are given. This shows the richness and variety of chemicals containes in each of the species listed, The chemicals listed may or may not prove to be important in the pharmaceutical sciences but is an indication of what each species contatin in thrms of plant chemicals, It is a well known fact that many of the pharmaceutical prescriptions in present day use are of plant origin and semi-synthetic or fully synthetic chemicals produced using knowledge gained from studies of phytochemicals. Thus the paper presented will give useful information and also shows the richness of plant species that have high potentials for the development of anti-cancer resources from plants in Malaysia.

The purpose of this study was to analyze the uses of the external representations in the $3{\sim}6th$ grade science textbooks developed under the 7th National Curriculum on the basis of the theories and the research results on learning with the multiple representations. The results showed that the frequencies of the macroscopic external representations were higher than those of the symbolic external representations. The external representations with drawing and/or writing, especially writing, were used more frequently than those without drawing and/or writing. However, the most of the external representations were rarely used according to the principles and/or the theories (e.g., personalization principle, dual coding theory, cognitive load theory, and social constructivism theory) for effective uses of the multiple external representations in the science textbooks. The present study provides the guideline to establish the effective uses of the external representations in the science textbooks that not only meet learners but also teachers.

A Rapid Thermal Processing (RTP) system operated below $500^{\circ}C$ has been designed and constructed. It uses an optical pyrometer for measuring wafer temperature, the sensing range of pyrometer is from $2.0{\mu}m$ to $2.4{\mu}m$. To remove the interference effect by IR emitted from lamps an IR filter is adapted which uses water. The best condition for Al alloy using the RTP system is $425^{\circ}C$ for ten seconds. The RTP system uses many lamps for supplying enough power in processing wafer because the absorption wavelength range of IF filter is from $1.3{\mu}m$ to $4.0{\mu}m$. However, reproducibility and uniformity is reduced due to the difference of lamp characteristics. Therefore, for improving the reproducibility and uniformity new RTP system using one lamp is designed. The new RTP system uses a focusing mirror and it focuses the light of lamp. The curverture of the focusing mirror is controlled to supply uniform power in processing wafer. The result of computer simulation shows the possibility of new RTP system using one lamp.

Purpose: This study aimed to investigate intensive care unit (ICU) nurses' actual and perceived glove uses for preventing healthcare associated infection. Methods: We observed nurses' donning glove by occasions and adherence to guideline for glove uses in four ICU in a single hospital. Total of 378 cases were observed from August 16 through October 6, 2020. Sixty one nurses of 66 nurses observed responded to a self-reported questionnaire about perceived glove use and knowledge of glove use. Data analysis was performed using descriptive statistics. Results: The number of observed episodes for glove use was 277. Although the highest numbers of occasions of wearing gloves was contact precaution, the compliance rate was 72.1%. The rates of donning gloves were low in the insertion and removal of peripheral venous catheters, blood glucose testing and blood sampling, which were at risk for exposure to blood. We observed misuse of wearing gloves even when they were not required. Results showed that the majority of non-compliance with glove use were a failure of performing hand hygiene before and after glove use and a failure of changing gloves between procedures on the same patient. The participant's knowledge of glove use was high. Conclusion: Based on the results, it is necessary to provide ICU nurses with education and reinforcement of proper glove uses for infection control.

Kung fu films stand out among many types of films and are sought after by a large number of loyal audiences. In order to explore the mystery, we use the theory of uses and gratifications theory to study kung fu films in order to explore the audience's viewing needs of kung fu films In the existing research, most scholars adopt qualitative research and Chinese culture contained in kung fu movies. Few people use quantitative research, and this area of research is almost blank. Therefore, we conducted a quantitative research on kung fu films based on the methodology of uses and gratifications. The questions revolve around: Can kung fu movies meet audiences' needs? What is the purpose of watching a kung fu movie? After analysis with SPSS, interesting results emerged. In the regression analysis, we found that the psychological need for compensation has a positive impact on Viewing satisfaction, while the social need has a significant negative impact on viewing intention. At the end of the article, we also put forward my own solutions. We also hope to provide better suggestions for the development of Chinese kung fu films through my research, so as to make kung fu films more perfect.

Background: Characterizing and describing soils and land use and make a suggestion for sustainable utilization of land resources in the Ethiopian Rift valley flat plain areas of Lake Chamo Sub-Basin (CSB) are essential. Objectives: To (1) characterize soils of experimental area according to World Reference Base Legend and assess the nature and extent of salinity problems; (2) characterize land use systems and their role in soil properties; and (3) identify best land use practices used for both environmental management and improve agricultural productivity. Methods: Twelve randomly collected soil samples were prepared from the above land uses into 120 composites and analyzed. Results: Organic carbon (OC) and total nitrogen (TN) were varied along different land uses and depleted from the surface soils. The soil units include Chernozems (41.67%), Kastanozems (25%), Solonchaks (16.67%), and Cambisols (16.67%). The identified land uses are annual crops (AA), perennial crops (PA), and natural forest (NF). Generally, organic carbon, total nitrogen, percentage base saturation (PBS), exchangeable (potassium, calcium, and magnesium), available phosphorus (P₂O₅), manganese, copper, and iron contents were decreased in cultivated soils. Soil salinity problem was observed in annuals. Annuals have less nutrient content compared to perennials in irrigated agriculture while it is greater in annuals under rainfed. Clay, total nitrogen, available phosphorus, and available potassium (K₂O) contents were correlated positively and highly significantly with organic carbon and electrical conductivity. Conclusion: Management practices that improve soil quality should be integrated with leguminous crops when the land is used for annual crops production.
