  • Purpose: This study was conducted to identify drug use by elders. Method: There were 304 participants age 65 or older included in this study. Data were collected using a questionnaire about drug use in the past 4 weeks. The questionnaire, a modification of Uhm's (2005), Lee's (2001), and Ellor and Kurz's (1982) tools, consisted of 17 questions on general and health characteristics, 17 on drug usage and 9 on behaviors related to drug misuse. Results: 85.5% of participants reported laking at least one type of prescription or non-prescription drug. 26.0% of participants reported taking only prescription drugs, 3.9% reported taking only non-prescription drugs, and 55.6% reported taking both prescription and non-prescription drugs. 17.1% of participants reported side effects from the drugs. The mean score for behaviors related to drug misuse was 7.53. Elders taking only non-prescription drugs showed more drug misuse than elders taking only prescription drugs or both. Women used more prescription, non-prescription drugs or both than man. Elders in rural areas used more non-prescription drugs than those in urban areas. Conclusion: Even though pharmacies were separated from medical practices in 2000, most older adults continue to use and misuse prescription and non-prescription drugs.

  • The authors utilized two contested perspectives on the use and non-use of ICTs, especially the Internet, to verify three assumptions of urban ghettos as fundamentally excluded from the ICT structure, ghetto people as behaving in the same way, and deficiency as the sole explanatory variable of their non-use. The first assumption that the urban ghettos would be fundamentally excluded from the urban ICT structure can be nullified by our finding about the prevalence of ICTs in that area, albeit apparent lower level of access to ICTs compared to that of the urban core. The second assumption that the urban ghetto residents would display the same information behaviors would be challenged by our finding that the availability and usages of the Internet would be hardly consistent by gender, age, occupation, family size, and locational characteristics. The third assumption that deficiency would capture the Internet non-use by ghetto residents was found very tenable but could be rivaled by the choice perspective that use or non-use is simply a result of situated choice. Theoretical and practical implications were suggested.

  • The Korean government is planning to invest a lot of funds for conservation of the soil. Accordingly, it needs quantitative information on the soil. This paper attempts to analyze the total value of soil quantitatively: the total economic value of soil can be divided into use value and non-use value. To this end, we apply a replacement cost method (RCM) and contingent valuation method (CVM). Especially, CVM is most widely used to measure the non-use value such as environment goods. We employed the one-and-one-half-bounded dichotomous choice (OOHBDC) for willingness to pay (WTP) elicitation and a spike model. The monthly mean WTP was estimated to be KRW 3,949 per household for the next 10 years, which is statistically significant at the 1% level. Expanding the value to the relevant population gives us KRW 897.9 billion per year and as of the end of 2015, the non-use value of soil was assessed to be KRW 838.6 billion. Meanwhile, use value is subdivided into direct use value and indirect use value. This value was calculated KRW 3,277 trillion and KRW 51.8 trillion, respectively. As a result, total economic value of soil is estimated to be KRW 3,330 trillion in Korea.

  • Land use change by urbanization has significantly affected the hydrological process including the runoff characteristics. Due to this situation, it has been becoming more complicated to manage non-point source pollutions caused by rainfall. In order to effectively control non-point sources, it is necessary to identify the reduction efficiency of the various management method based on land use characteristics. Thus, the purpose of this study is to analyze the reduction efficiency of non-point source pollution management practices targeting three different watersheds with the different land use characteristics using the Soil and Water Assessment Tool (SWAT). To do this, the vulnerable subwatersheds to non-point source pollution occurrence within each watershed were selected based on the streamflow and water quality simulation results. Then, considering the land use, low impact development (LID) or best management practices (BMPs) were applied to the selected subwatersheds and the efficiency of each management was analyzed. As a result of analysis of the non-point source pollution reduction efficiency, when LID was applied to urban areas, the average reduction efficiencies of SS, NO3-N, and TP were 5.92%, 4.62%, and 10.35%, respectively. When BMPs were applied to rural areas, the average reduction efficiencies of SS, TN and TP were 35.45%, 4.37%, and 10.16%, respectively. The results of this study can be used as a reference for determining appropriate management methods for non-point source pollution in urban, rural, and complex watersheds.

  • The demand for non-contact service has increased a lot along with the development of technology and the generalization of social distancing to prevent COVID-19 spread during the pandemic. This study analyzed mediator and moderating variables between digital literacy and intention of continuous use of non-contact service were identified. The result showed that digital literacy had a significant influence on intention of continuous use of non-contact service. In particular, self-efficacy and satisfaction played a moderating role in the relation between digital literacy and intention of continuous use of non-contact service. This study is intended to contribute to expanding the base of non-contact service by verifying whether satisfaction and self-efficacy played important mediator variables in the relation between digital literacy and intention of continuous use of non-contact service

  • Mobile payment system using NFC attracted attention as the mobile payment market grows due to the fast diffusion of smart phones. However, non NFC mobile payment recently appeared because of the slow growth of infrastructure for NFC. With advent of Non NFC mobile payment applications, mobile payment industry is in developing trend. Non NFC mobile payment revitalizes the market by overcoming the limit of NFC with the smart applications using bar code and QR code payment, and providing various discounts, membership benefits and payment information. Therefore, this paper analyzed the intention of continuous use with the quality of mobile payment application based on the information system success model. Three categories of factors which are system quality, service quality, and information quality were used. We verified the significance of the factors affecting the intension of continuous use. mainly, quality of information was considered as an important factor of continuous Intention to Use. Also, unlike previous NFC, it was found that in Non-NFC, compatibility might not be as important factor. Moreover, we suggest a marketing strategy of companies for mobile payment industry which focus on information quality. and future research directions for non NFC payment market.

  • Objectives: The objective of the study was to investigate the factors related to non-use of interdental care products (ICP) in adolescents. Methods: The 2019 Korean Youth Risk Behavior Web-based Survey was used, examining 57,303 subjects. Complex-sample chi-square test and logistic regression analyses were performed to identify differences in ICP according to sociodemographic characteristics and oral health behavior and to determine the factors related to non-use. Results: The ICP non-use rate was 70.9%. Factors related to the non-use of ICP were middle or low economic status (OR=1.367 and 1.677). The other significant variables were less than one tooth brushing per day (OR=1.542), no scaling within 12 months (OR=1.631), and receiving dental treatment either once or two times or more (OR=1.757 and 2.195). Conclusions: To increase the ICP usage rate, continuous attention is needed from schools and families in addition to interventions at the national level.

  • This study is to test the applicability of QuickBird image for non-point source pollution assessment. SWAT (Soil and Water Assessment Tool) model was adopted and the model was calibrated for a stream watershed of 255.4 $km^2$ Landsat land use data. For model application with QuickBird image, a precise agricultural land use map of 1.16 $km^2$ area located in the upstream watershed was produced by field investigation. The model was run with the combination of land use and soil map scales (1:5,000, 1:25,000 and 1:50,000). The results were compared and analyzed for the contribution of non-point source pollution by the land use scale and contents.

  • This study estimated the non-use values of the Gum river estuary which are not related to the direct or indirect use of the Gum river estuary using the contingent valuation method (CVM). The non-use values of the Gum river estuary were explained and asked to be evaluated in the CVM questionnaire and estimates of the WTPs(willingness-to-pay) were elicited using the Turnbull nonparametric estimation methods on the dichotomous choice CV data. Results found the Turnbull lower bounded mean WTP per year for non-use value of the Gum river estuary was estimated at 5,822 won (95% C.I. 5,295 ~ 6,349 won) from single dichotomous CV data, and 6,205 won (95% C.I. 5,701 ~ 6,710 won) from double dichotomous CV data. The mean of two WTP estimates, 6,014 won (95% C.I. 5,498 ~ 6,529 won), was used to calculate the annual total non-use value of the Gum river estuary. Therefore, the non-use value of the Gum river estuary was estimated at 220.3 billion won (95% C.I. 201.4 - 239.2 billion won) annually. This non-use value of the Gum river estuary was composed of the bequest value totaling 68.3 billion won (95% C.I. 62.5 - 74.2 billion won), the existence value of 58.0 billion won (95% C.I. 53.0 - 63.0 billion won), the option value of 57.7 billion won (95% C.I. 52.7 - 62.6 billion won), and the vicarious consumption value totaling 36.3 billion won (95% C.I. 33.1 - 39.4 billion won).
