This study has attempted to investigate the time use of the elementary school students and their satisfaction levels by their general characteristics for the educational guidance. The sample of this study consisted of 387 elementary school students on Jeju Island who are in the fifth or sixth year. The data were analysed by frequency, percentage, mean, t-test, ANOVA and Duncan's test. The major results of this study were as follows; The results of this study showed that the students spent much time for studying including extra programs as like their ages. Also, their leisure time focused on watching TV or doing computer. The levels of satisfaction according to the time use were slightly high although their time allocation was not various. The time use of the students and their satisfaction levels were significantly affected by the general family situation related to parents as well as their own characteristics. The variables such as the student's sex, parent's educational level, whether the mother is employed or not, and monthly allowance were important to result in the differences of the time use and satisfaction levels among the students. The leisure time was strongly related with the satisfaction levels.

Purpose: The purpose of the study was to investigate the effect of loneliness on habitual drug use in Korean adolescents. Methods: The study was designed as a cross-sectional study. Using statistics from the 16th (2020) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. A total 54,948 adolescents were included in the analysis. Results: Adolescents were more likely to engage in habitual drug use when they were lonely than when they were not (OR: 1.55, 95% CI: 1.20~2.02). As for sociodemographic characteristics, gender, academic achievement, and living with family were factors influencing habitual drug use. As for health behavior characteristics, perceived stress, depression, current drinking, violence, sexual intercourse, and perceived health were identified as factors affecting habitual drug use. Conclusion: Provision of education that includes loneliness as a factor, which was not previously considered important in school education for preventing habitual drug use of adolescents, should be considered.

The purpose of this study is to understand the formative characteristics of futuristic virtual fashion revealed in virtual fashion platforms targeting the human body. First, the current status of fashion in the metaverse and futurist fashion were reviewed and summarized by referring to prior research. Next, among the items posted on DRESSX, "futurism" was searched and those resturning a positive result were collected as research subjects. The characteristics were organized into design elements: colors, shapes, materials, and patterns. Futuristic aesthetic characteristics were derived from the characteristics of each design element. As a result, color showed the characteristics of achromatic, vivid and neon colors, multi-color and gradation, multi-color due to reflected light, and color conversion. As for the form, a body-concious look or exaggerated silhouettes, spatial expressions in geometric structures, forms imitating living things, and fluid silhouettes using clouds were prominent. Materials showed the digitization of universal clothing materials, application of industrial materials, use of metal materials, and unrealistic materials. In the patterns, geometric abstract patterns, patterns that reveal the digital world view, and moving fluid patterns appeared. The aesthetic characteristics of futurism in virtual fashion were revealed in four categories: visual dynamics, high-tech sensibility, variability, kineticisim. Visual dynamics were revealed in geometric forms, and intense neon colors. High-tech sensibility was prominent in the use of metal and industrial materials, light emission, and patterns of the digital world view. The expression of multiple colors by reflected light and the change showed the variability of futurism. The use of unrealistic materials, such as clouds and fire and fluid silhouettes expressed kineticisim. The infinite expressiveness of virtual fashion made it possible to actively express the aesthetic characteristics of futurism.

For effective watershed management, we must understand the complex and dynamic relationships of land uses and water quality. Despite numerous studies investigated the relationships between water quality and land use, there are increasing concerns on the geographical variation and lack of spatial integrations in previous studies. We investigated the relationships between land use and water quality characteristics in the Hwa-Sung estuarine reservoir watershed in Korea, which has spatially integrated land uses. The spatial variations of these relationships were also examined using zonal analysis. Water quality parameter were correlated positively with residential and forest and negatively with paddy and upland especially during base flow in the near buffer zone. During storm flow, correlation between land use and water quality was less apparent. Population and livestock density was correlated well to water quality parameter than just number of population and livestock. Relationships across zones, distinguished by distances from streams, were inconsistent and erratic, suggesting that the relationships between remote land uses and water quality may be affected more significantly by sub-basin characteristics than by the land use itself. The watersheds studied are mainly non-urban and their land uses are similar to typical watershed of other estuarine reservoirs, therefore, the correlation developed in this study might be helpful to manage other watersheds of estuarine reservoir. This methodology could be applied to other areas where the watershed characteristics are not significantly different from the study area.

Land use types within a watershed closely are related with the water quality characteristics of receiving water bodies. Despite of a numerous studies suggesting a strong relationship between water quality and land use, there have been increasing concerns about the geographical variation and a lack of spatial integration in that relationship, which are essential to implementing these findings into land use planning and management. In the meantime, edges mediate the material flux between adjacent systems. This mediating effect of edges is strongly related to the complexity of their shapes. Land use activities within a watershed have a direct impact on the water quality of adjacent aquatic systems, and hydrological processes carry residuals from watershed into adjacent aquatic ecosystems through the edges. Therefore, the geometry of reservoirs theoretically affects the relationship between land uses in the watershed and the quality of receiving bodies of water. In this light, this study integrates the geo-spatial dimensions of land uses in the watershed using GIS and landscape indices in order to explore the relationship between land uses and water quality. Water quality characteristics, land uses and geometry of 133 randomly sampled reservoirs were correlated, based on buffer zones and types of reservoirs. The findings showed that land uses, particularly urban land uses, significantly affect water quality characteristics including BOD, COD, TN and TP, and geometry of reservoirs reduces the concentration of pollutant and nutrients in reservoirs. One of results indicates that the relationship between land use and water quality and effects of spatial dimension may vary with types of reservoirs and pollutants. These results suggest that lakeshore areas are important, particularly for TN reduction and call for a caution to land use activities nearby shoreline areas for sustaining better water quality.

Inappropriate antibiotic use significantly contributes to antibiotic resistance, resulting in reduced antibiotic efficacy and an increased burden of disease. The objective of this study was to investigate the characteristics of prescribers whose antibiotics use was high and to explore factors affecting the use of antibiotics by medical institutions. This study analyzed the National Health Insurance claims data from 2015. Antibiotic prescription data were analyzed in terms of the number of defined daily doses per 1,000 patients per day, according to the World Health Organization anatomical-therapeutic-chemical classification and methodologies for measuring the defined daily dose. We investigated the characteristics of prescribers and medical institutions with high antibiotic use. Multivariate regression analyses were performed on the basis of characteristics of the medical institution (number of patients, type of medical institution [hospital or clinic], age of the physician, etc.). The number of patients and number of beds were found to be significant factors affecting antibiotic use in hospitals, and the number of patients, region, and medical department were significant factors affecting antibiotic use at the level of medical institutions. These findings are expected to help policy-makers to better target future interventions to promote prudent antibiotic prescription.
