Purpose: The prevalence of problematic internet usage among college students is a cause for concern. There is a lack of study examining influences of cognitive protecting or buffering factors on internet addiction among college students. The purpose of this study was to examine influences of depression, ego-resilience, and active stress coping on internet addiction tendency (IAT) among college students. Methods: A cross-sectional, descriptive design was used. Data were collected between October and December 2013. A convenience sample of 244 students completed self-report questionnaires consisting of Ego-resiliency Scale, Ways of Coping Checklist, Center for Epidemiologic Studies-Depression, and Self-report Scale for Internet Use. Stepwise multiple regression analysis was performed for data analysis. Results: We found that higher levels of depression were associated with higher levels of IAT. However, an inverse association was found between active stress coping and IAT. Students who mainly used the internet for chatting showed lower levels of IAT than those who used the internet for games or blogs. These factors explained 15.1% of the variance in IAT of college students. Conclusion: The study results suggest that stress coping strategies and depression are important factors for evaluation when developing intervention programs targeting college students with problematic internet use.

Antioxidant films are one active packaging technology that can extend food shelf-life through preventing lipid oxidation, stabilizing color, maintaining sensory properties and delaying microbial growth in foods. Because raw, fresh and minimal processed foods are more perishable during storage or under display conditions than further processed foods, they rapidly lose their original quality. Foods are susceptible to physical, chemical, and biochemical hazards to which packaging films can be effective barriers. Although films incorporated natural (tocopherols, flavonoids and phenolic acids) or synthetic antioxidants (BHT, BHA, TBHQ, propyl gallate) have been extensively tested to improve quality and safety of various foods, food applications require addressing issues such as physical properties, chemical action, cost, and legal approval. Increased interest in natural antioxidants as substitutes for synthetic antioxidants has triggered research on use of the new natural antioxidants in films and coatings. Use of new components (phytochemicals) as film additives can improve food quality and human health. The biosynthesis of plant phenolics can potentially be optimized by active coatings on harvested fruits and vegetables. These coatings can trigger the plants natural proline-linked pentose phosphate pathway to increase the phenolic contents and maintain overall plant tissue quality. This alternate metabolic pathway has been proposed by Dr. K. Shetty and is supported by numerous studies. A new generation of active food films will not only preserve the food, but increase food's nutritional quality by optimizing raw food biochemical production of phytochemicals.

Active catalog is a kind of digital content that enables consumers to test the functions and features of products from their PCs as if they were using it in real life, by simulating the actions and responses of the product. This new type of interactive digital content can be used extensively to make sales personnel training manuals, sales tools, user manuals and user trouble shooting documents. With active catalogs, companies will be able to compare different designs, show actions according to different functions, and evaluate user reaction to new products without having to produce a single physical prototype or mock-up. At the same time, consumers will be able to understand and 'operate' the product and make well-informed purchase decisions. In this paper, we present a visual event-driven modeling tool, PlayMo, for creating active catalogs, analyze the advantages of using PlayMo, describe the event-driven method used by PlayMo and also introduce two enhanced characteristics of the Event Flow Chart with which the events in PlayMo are structured. Interactive digital content by using the PlayMo3D makes easy, simple and effective design for e-learning, e-catalogue, e-marketing/sales, e-prototyping, customer support, etc. Through its application-ready 3D function visualization solution, engineers and designers can rapidly turn a CAD design model into a 3D interactive virtual product, and the effective function prototyping job can be also completed within a minute.

This study recognizes that consumers are becoming important as a subject of commerce as they change from the existing e-commerce market to the consumer-led e-commerce market, and proposes the use of consumer intervention as a remedy for consumer damage in international e-commerce disputes. In Korea, there is no separate regulation on consumer arbitration, so we will analyze the U.S. arbitration judgment, which is the most active in consumer arbitration, and examine it through the U.S. arbitration judgment so that arbitration can become active as a remedy for consumer disputes in Korea. In summary, in the event of a dispute between consumers and companies through e-commerce, consumers' preference for arbitration was confirmed through repeated collection of opinions without coercion. It is necessary to revitalize arbitration in Korea to protect consumers through arbitration rather than litigation and to resolve disputes through active alternative dispute resolution as a solution to disputes in e-commerce, which is rapidly increasing through U.S. consumer arbitration cases. The topic of the activation of arbitration has been mentioned a lot before, but the preference for arbitration is still lower than that of litigation. However, from now on, as the appearance of existing commerce has changed to consumer-led e-commerce, it has proposed a plan to use arbitration to rescue consumers from damage as consumers as buyers grow in the market.

This study was investigated to review the potentials of irritation and skin sensitization of active ingredients and end-use products of pesticides for pesticide registration, prediction of irritation and sensitization, and data requirements for other purposes. Pesticide irritation and sensitization referred to the Pesticide Manual(14th edition), while toxicity was evaluated based on the data submitted by the pesticide registrant. Totally 148 active ingredients and 149 end-use products were analyzed to compare the positive response, formulation type, and correlation between active ingredients and products. Among active ingredients, ratio of positive response to skin irritation, eye irritation, and skin sensitization were 18.8, 47.0 and 20.6% respectively. While, positive response to skin irritation, eye irritation, and skin sensitization of the products were 14.9, 38.9 and 23.6%, respectively. Emulsifiable concentrate showed the highest positive response among formulation types showing skin irritation 31.3%, eye irritation 81.3%, and skin sensitization 31.3%. On the other hand granule type showed the lowest response with skin 4.8, eye 14.3 and sensitization 14.8%. There was no correlation by active ingredient content on irritation and sensitization of products. However, both active ingredients and products showed same positive response were skin 73.1%, skin sensitization 66.2%, and eye irritation 44.7%. By the these results, correlation between technical grade of active ingredients and end-use products would be use for pesticide management at the screening stage, especially skin irritation and skin sensitization.

This study examined the relationship between the physical activity levels and health care utilization in Korean elderly based on the data from The fifth Korean National Health and Nutrition Examination Survey (K-NHANES V). As a result, physically active participants were 0.54 times (OR;95% CI, p<0.001) less likely to use inpatient health care and 0.73 times (OR;95% CI, p=0.040) less likely to use outpatient health care and 0.75 times (OR;95% CI, p<0.007) less likely to use drugstores than physically inactive participants, and the frequency of health care use was lower. In addition, physically minimal active participants were 0.64 times (OR;95% CI, p<0.001) less likely to use inpatient health care than physically inactive participants; the frequency of other health care facilities was lower. In conclusion, the relationship between being physically active and lower health care utilization among Korean elderly identified in this study. This suggests that being physically active is helpful to the elderly, not only in health promotion and improving quality of life, but also in reduced medical expenditure.
