This study investigates to investigate the factors that influence user resistance of mobile payment services. We suggested individual and technical characteristics of mobile payment services as factors influencing perceived risk and user resistance. In addition, we suggested negative security recognition as moderating variable. To test the proposed hypotheses, we collected 349 survey responses from the users of mobile payment services and conducted structural equation modeling with SmartPLS2.0. The results show that, first, negative social influence, risk aversion and distrust in existing services had an effect on the perceived risk. Second, the pace of change and vulnerability had an effect on the perceived risk. Third, perceived risk affected the user resistance while negative security recognition is related to the relationship between perceived risk and user resistance.

The ACF(Anisotropic Conductive Film) is used for bonding Drive IC and OLED display device panel. If ACF bonding process is problem, a malfunction of line defect can occur. Because electric resistance increase between the panel and drive IC after a period of time, drive IC can not supply enough current to the panel. This paper is studied on a method of test for line defect.

Acute otitis media and acute sinusitis are some of the most common antibiotic-prescribed diseases in childhood. Usually, with an accurate diagnosis, a 10-14 day course of antibiotics is recommended to cover common causative agents, including pneumococci. Establishment of management guidelines for these infectious diseases based on further study of the epidemiologic profile, antibiotic resistance, and clinical circumstances in Korea is needed.

Thermal management is very important for the success of high density circuit design in LTCC. To realized more accurate thermal analysis for structure design, a series of simple thermal resistance measurement by laser flash method and parametric numerical analysis have been carried out. The design of via filled material would be useful in thermal management of power devices.

The recent dramatic growth of ERP has changed the way organizations conduct their businesses, and resulted in significant tangible and intangible benefits being realized by participating firms. Despite these various benefits, firms still have problems in implementing and diffusing ERP due to some reasons, such as resistance to the change. This study primarily aims at identifying what factors are significantly affecting the diffusion of ERP system and finding out how these identified factors can be effectively managed.

The steps related to the nutrient solution management were divided into 4 categories. The resistance for water movement in every steps was proposed. The priorities among the steps were set according to the cultural situation, which were used as the basis for the management in perlite bag culture. The enhancement of historical root development is especially critical, as well as how to supply essential water efficiently by minimizing the water movement distance to the root, which is the narrowest neck of a bottle in solution management.

This research proposes a conceptual framework to highlight the importance of change management after firms implement ERP systems. With ERP, firms need to rework their business processes to make information flow smoothly within organizations. Firms cannot realize expected returns from ERP investments unless changes are effectively managed after ERP systems are put into operation. The research model is empirically tested using data collected from over 170 firms that had used ERP systems at least for more than one year. Our analysis reveals that the eventual success of ERP systems depends on effective change management after ERP implementation, supporting the existence of the 'valley of despair.

The e-Book market has rapidly grown as an innovative product which is mixed its traditional and technological characteristics. However, decreasing user resistance to the e-Book is very important to continually keeping up its market growth. Previous studies for user resistance have been studied as a negative barrier for various innovative products with importance of user resistance. Nevertheless, the factors for user' resistance to the e-Book field have not been found out considering both perceived value and switching cost. Especially, both innovative technology and user specifics should be considered when explaining user resistance to adopting e-Books. Thus, the purpose of this study is to understand the process for user resistance to the e-book and find out its antecedents with perceived value and switching cost at the same time. As a result, it appeared that triability, uncertainty and complexity affected perceived value and switching cost. The user-based antecedents like social norm and perceived value increased the effect of self-efficacy. Also, self-efficacy and perceived value decreased user resistance whereas switching cost increase user resistance to the e-Book perspective.

Repeated use of ACCase inhibiting herbicides for a long time has resulted in increases of resistant Echinochloa oryzicola populations in paddy fields in middle west area of Korea. This study aims to investigate current status of herbicide resistant E. oryzicola in Gyeongsangnam-do, in which there is less information about herbicide resistance. For resistance frequency and dose-response study, seeds from 100 individual plants of E. oryzicola in Gyeongsangnam-do were collected and tested with cyhalofop-butyl. Seven percent of plants from Gyeongsangnam-do was resistant at a recommended rate of cyhalofop-butyl. $GR_{50}$ values (herbicide rates required to reduce plant growth 50%) for one representative resistant populations and five susceptible populations were $738g\;a.i.\;ha^{-1}$ and 66-234 (average 147)$g\;a.i.\;ha^{-1}$, respectively, indicating average 5 times difference in resistance. Although lower rate of frequency of herbicide resistance in Gyeongsangnam-do than in Jeollabuk-do, increases of herbicide resistance are expected in this area because of increases of direct seeded rice fields and increases of dependence on a specific herbicide. Therefore, it is necessary to monitor herbicide resistance regularly and conduct integrated herbicide resistance management in this area.

The purpose of this study was to examine the effect of 16 weeks of resistance training on the fatigue factor, muscle soreness, oxidative stress, and myokine in elite weightlifters. A total of 10 subjects (six male, four female) participated in this study. The results were compared according to baseline, 8 weeks, and 16 weeks. Ammonia and Pi were increased through 16 weeks of resistance training, but this result was not significant. CK was significantly (p<0.05) increased at 8 weeks and 16 weeks compared to baseline, while LDH was significantly (p<0.05) increased at 8 weeks compared to baseline. The MDA of the oxidative stress factor was significantly (p<0.05) increased at 8 weeks compared to baseline and 16 weeks, and TAS of the antioxidant factor was significantly (p<0.05) increased at 8 weeks compared to baseline. The IL-15 of the myokine was significantly (p<0.05) increased at baseline compared to 8 weeks and 16 weeks. In conclusion, 16 weeks of high-intensity resistance training may have a positive effect on peripheral fatigue factors, muscle soreness, oxidative stress, and myokine in elite weightlifters.
