  • Objectives: Previous observations propose that risk-taking behaviors such as cigarette smoking are prevailing among young people with chronic conditions including diabetes. The purpose of this study was to examine whether cigarette smoking is more prevalent among diabetics than non-diabetics and whether it differs by age at the time of diagnosis with diabetes from young adulthood (YAH) to adulthood (AH). Methods: We used US panel data from the National Longitudinal Study of Adolescent Health (Add Health Study) during the years 2001 to 2002 (Wave III, YAH) and 2007 to 2008 (Wave IV, AH). Multivariate logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of cigarette use behaviors according to age at the time of diagnosis with diabetes, after adjusting for demographic and selected behavioral factors. Results: Of 12 175 study participants, 2.6% reported having been diagnosed with diabetes up to AH. Early-onset diabetics (age at diagnosis <13 years) were more likely than non-diabetics to report frequent cigarette smoking (smoking on ${\geq}20$ days during the previous 30 days) in YAH (OR, 3.34; 95% CI, 1.27 to 8.79). On the other hand, late-onset diabetics (age at diagnosis ${\geq}13$ years) were more likely than non-diabetics to report heavy cigarette smoking (smoking ${\geq}10$ cigarettes per day during the previous 30 days) in AH (OR, 1.54; 95% CI, 1.03 to 2.30). Conclusions: The current study indicated that diabetics are more likely than non-diabetics to smoke cigarettes frequently and heavily in YAH and AH. Effective smoking prevention and cessation programs uniquely focused on diabetics need to be designed and implemented.

  • Background: Dopamine receptor agonists (DRAs) have been associated with impulse control disorders (ICDs) in Parkinson's disease (PD) in preliminary studies. Whether the association holds true when DRAs are used to treat non-PD, such as restless legs syndrome, prolactinoma, and several mood disorders is uncertain. Objective: The present study aimed to understand the research gaps related to the risk of ICDs associated with pramipexole or ropinirole (PRX/ROP) use as a treatment for specific underlying diseases, excluding Parkinson's disorders. Methods: We conducted a scoping review, systematically searching databases to identify literature on the types, prevalence, and factors associated with ICD in non-PD patients receiving PRX/ROP. All relevant information that helped understand the epidemiology of ICDs among non-PD patients taking PRX/ROP were extracted and analyzed. We also evaluated the potential associations between PRX/ROP and ICDs, utilizing the Naranjo scale or statistical analysis, depending on the type of literature. Results: We included 24 articles (19 case reports or case series and 5 population-based studies) in this scoping review. Evaluating the 19 case reports or case series using Naranjo scores led to the discovery of a possible link between PRX/ROP exposure and ICDs. However, important information to assess causality is frequently missing. Moreover, the population-based studies lack diversity in the study populations and enough study samples to draw conclusive results. Conclusion: Our scoping review suggests that the currently available literature requires more details in future case reports and for well-powered studies in various disease conditions where PRX/ROP is frequently used.

  • This research examines factors affecting behavioral intention to use integrated platform (IP), which is one of the business models regarding paid digital contents, based on extended United Theory of Acceptance and Use of Technology (UTAUT2). IP is a service which is designed to make digital content charged. It combines digitalized format of newspaper, premium news or behind news, and additional information. The results of this paper show that effort expectancy, social influence and hedonic motivation have positive relationship with behavioral intention to use IP (BI). Satisfaction with newspaper shows negative relationship with BI, which means that newspaper and IP can be replaced with each other. Newspaper subscribers tend to have higher BI than non-subscribers. Performance expectancy, gender, age, and satisfaction with website do not have significant effect on BI.

  • Purpose - Inducing consumers' behavioral intent to use an outlet shopping center is a critical issue for managers since it can be used as a guide for developing marketing strategies. Low prices could lead to a growth in retail purchases, but there might also be a positive relationship between prices and customer perceptions of product quality. The extent to which consumers use price as a predictor of quality may differ according to the availability of important alternative cues such as brand, store name, and identity salience triggered by the store. Consumers can obtain non-economic benefits from marketing exchanges that go beyond basic economic achievement. We argue that identity salience can play a crucial mediating role when consumers, acting as exchange partners, seek to obtain social benefits. This study shows that identity salience could mediate the relationship between identity salience-inducing factors such as multi-finality, prestige and role performance, and consumers' behavioral intent to use an outlet shopping center. Research design, data and methodology - The survey was conducted on college students enrolled in marketing classes. A total of 200 questionnaires were distributed, of which only 194 were returned. After five incomplete questionnaires were excluded, a final sample of 189 was used for empirical analysis. Using a covariance structural analysis in Amos17, we confirmed the fit of the research model and estimated its parameters by using the maximum likelihood method. Results - The results of the hypotheses testing are as follows. First, both identity salience and economic benefits have positive effects on the behavioral intent to use an outlet shopping center. Second, role performance, prestige, and multi-finality have positive effects on identity salience. Finally, the additive analysis of the direct effects of identity salience-inducing factors shows that the role performance, prestige, and multi-finality factors have no direct effects on the behavioral intent to use an outlet shopping center, suggesting that identity salience plays a positive mediating role. Conclusions - This study informs marketers that not only price but shoppers' identity salience directly affects their intent to visit an outlet shopping center. To strengthen shoppers' identity salience, marketers should find ways to help shoppers fulfill their multiple social roles, realize their multiple goals, and achieve prestige. In other words, outlet shopping centers must improve their personal service environment in order to enhance their employees' service quality and assist the execution of multi-finality by minimizing the perceived costs (e.g., travel time, effort) associated with shopping trips, thus making it easier for consumers to combine visits to multiple stores in outlet shopping centers and buy the items required for their consumption goals. Outlet shopping centers must also offer assortments with both breadth and depth in order to help consumers play the social roles their social networks have given them.

  • Real options valuation models are now proved as a effective valuation method both in Theoretically and empirically. However, to use real options model for early stage start-ups, additional non-financial information is crucial in the valuation process. Previous studies theoretically suggested the modified real options valuation model and process to use non-financial information in the valuation of early stage startups, but there is no empirical evidence on the suggested model. Therefore, this study investigated the effectiveness of the modified real options valuation model using a case study. The case study result showed that the modified real options valuation effectively reflect the non-financial information in early stage startups, and decrease the forecasting error in the valuation process.

  • Twenty-four wetlands located in Higashi-Hiroshima City in West Japan were selected for this study in order to investigate both the relationship between aquatic plant composition and environmental conditions; and the relationship between changing land use patterns in the catchments and the concentration of different forms of nitrogen in the wetlands. The dominant and subdominant species which comprised the principal vegetation were determined based on a vegetation census conducted in each wetland during the growing season from June to August, 2006. The seasonal variations of water quality factors (pH, electrical conductivity, turbidity, dissolved oxygen, total dissolved solid, and temperature) and different forms of nitrogen such as nitrite, nitrate, ammonium, total nitrogen, dissolved organic nitrogen and dissolved inorganic nitrogen concentrations were analyzed as important indicators of water quality for the surface water of the wetlands. The surveyed wetlands were classified into three types (non-disturbed wetlands, moderately-disturbed wetlands and highly-disturbed wetlands), based on the degree of human disturbance to their catchment areas. An analysis of variance indicated that there was a significant difference among the wetland groups in the annual mean values of electrical conductivity, total dissolved solids, total nitrogen, nitrite, dissolved inorganic nitrogen and dissolved organic nitrogen. Classification of the wetlands into three groups has revealed a pattern of changes in the composition of plant species in the wetlands and a pattern of changes in nitrogen concentrations. A majority of the non-disturbed wetlands were characterized by Brasenia schrebi and Trapa bispinosa as dominant; with Potamogeton fryeri and Iris pesudacorus as sub-dominant species. For most of the moderately-disturbed wetlands, Brasenia schrebi were shown to be a dominant species; Elocheriss kuriguwai and Phragmites australis were observed as sub-dominant species. For a majority of the highly-disturbed wetlands, Typha latifolia and T. angustifolia were observed as dominant species, and Nymphea tetragona as the sub-dominant species in the study area. An analysis of land use and water quality factors indicated that forest area played a considerable role in reducing the concentration of nutrients, and can act as a sink for surface/subsurface nutrient inputs flowing into wetland water, anchor the soil, and lower erosion rates into wetlands.

  • Metal binding activity of the pectin samples with different physicochemical properties was studied. It was found that in vitro copper binding capacity of pectins is depending on the following factors: degree of esterification, content of non-methylated anhydrogalacturonic acid, and pH of solution. There was found that the maximum copper uptake capacity increases correspondingly to reduction of the degree of esterification of pectin, rise of the non-methylated anhydrogalacturnic acid content and the solution pH. It is proposed to use for standardization of pectin samples such parameters as the degree of esterification, content of anhydrogalacturonic acid, and intrinsic viscosity.

  • This study was conducted to examine the medication non-adherence and related factors based on medication adherence model of older adults that use polypharmacy. A survey was used to collect data from 190 study participants. Among the 190 subjects, 43.2% did not adhere to their polypharmacy intentionally. The reason for medication non-adherence was listed in order of 'when they felt well on symptoms', 'when it was annoying and uncomfortable', and 'when they felt worse due to medication'. Moreover, the older adults often do not seek for medication information actively. Between adherence and non-adherence groups, while there were differences in gender, type of medication, and experience in drug-related side effects, there were no statistically significant differences in medication information contents and route. This study demonstrates that gender, type of medication, and experience in drug-related side effects should be considered to promote medication adherence. In addition, since the elderly with polypharmacy are rarely actively searching for the contents and route of drug information, the contents of drug information need to be provided by the route preferred by the elderly in order to assist in their decision-making process for polypharmacy.

  • In this study, the TOC in six estuarine reservoirs in the West Sea (Ganwol, Namyang, Daeho, Bunam, Sapkyo, and Asan) was estimated using optically-active water quality factors by the water environment monitoring network. First, specification data and land use maps of each estuarine reservoir were collected. Subsequently, water quality data from 2013 to 2020 were collected. The data comprised of 11 parameters: pH, dissolved oxygen, BOD, COD, suspended solids (SS), total nitrogen, total phosphorus, water temperature, electrical conductivity, total coliforms, and chlorophyll-a (Chl-a). The TOC in the estuarine reservoirs was 4.9~7.0 mg/L, with the highest TOC of 7.0 mg/L observed at the Namyang reservoir, which has a low shape coefficient and high drainage density. The correlation of TOC with water quality factors was also analyzed, and the correlation coefficients of Chl-a and SS were 0.28 and 0.19, respectively, while the correlation coefficients of these factors in the Namyang reservoir were 0.42 and 0.27, respectively. To improve the estimation of TOC using Chl-a and SS, the TOC was averaged in 5 mg/L units, and Chl-a and SS were averaged. Correlation analysis was then performed and the R2 of Chl-a-TOC was 0.73. The R2 of SS-TOC was 0.73 with a non-linear relationship. TOC had a significant non-linear relationship with Chl-a and SS. However, the relationship should be assessed in terms of the spatial and temporal variations to construct a reliable remote sensing system.
