Internet addiction, one of adverse effects of the informatization, has become a very serious social problem. The purpose of this study is to seek solutions for the adverse effects of the informatization by analyzing the causal factors of internet addiction to maximize prevention of the internet addiction for college students. The three causal factors of the internet addiction: personal factors, familial factors, and social environmental factors are defined as the second confirmatory factors, and the first confirmatory factors for the each second confirmatory factor are reviewed for influential factors of internet addiction. The study concluded that the personal factors are the most influential factors of internet addiction for college students; furthermore, self-control and self-efficacy are key variables of the personal factors. Therefore, it can be effective ways to prevent internet addiction if countermeasures on self-control and self-efficacy of the personal factors are presented.

The purpose of this study is to increase the competitiveness of big data in the maritime port organization, by understanding the expected performance and the intention to accept and use big data. In the empirical analysis of factors affecting the intention to use the big data technology for maritime port organizations, the variables employed are based on the Technology Organization Environment(TOE) and Diffusion of Innovations(DOI) theories, which are related to the acceptance of information and communication technologies. To achieve the objective of this study, an empirical analysis was conducted; this analysis targeted the personnel involved in the department of strategic planning and information technology in the related field. We set up eight hypotheses to examine the relevance between variables having three characteristics-technology, organization, and environmental characteristics. The empirical results are summarized as follows. First, it was seen that the technology characteristic, including relative advantage, complexity, and compatibility, has a significant effect on the expected performance. Second, the top management support of the organization characteristic has a significant effect, but the firm size of this characteristic has no significant effect on the expected performance. Third, the competitive pressure of the environment characteristic has a positive effect on the expected performance, while the regulatory support has no significant effect. Finally, the expected performance has a significant effect on the intention to use big data.

Individual phenotype is mostly influenced by genetic factors as well as the effects of environmental factors. Therefore, adjustment of environmental factors are needed in order to see more clearly the effects of genetic factors that we are interested in gene screening study related to Hanwoo's economic trait. The purpose of this study is to propose new statistical model that was adjusted environmental factor and identify adjustment effect in a superior gene marker screening study for producing high quality Hanwoo. First, statistical model including both genetic factor and environmental factor establishes and adjusted value of economic trait find by removing effect of environmental factor such as age, breeding farm. Finally, we identify superior gene marker combination and compare accuracy by applying MDR to data of before and after adjustment. Economic trait is used C18:1, SFA, MUFA, MS, CWT, BFT and SNP marker is used 6 markers of LPL that were identified as more excellent SNP marker than the others among 49 markers through fatty acid composition and economic trait performance test.

The purpose of this study is to seek solutions for the adverse effects of the informatization by analyzing the influential factors of internet addiction to maximize prevention of the internet addiction for highschool students. The causal factors of the internet addiction are classified into three categories: personal factors, familial factors, and social environmental factors. To validate the study, the questionnaires were given to four high schools which were two generalized high schools and two specialized high schools in the Seoul and Kyunggi Area. The most influential factor of the internet addiction was identified, and hierarchical influence among factors were analyzed by evaluating the questionnaires. The result of the generalized high schools was different from that of the specialized high schools. It proved that different countermeasures must be prepared depending on environment of internet users. Therefore, diverse and comprehensive solutions for internet addiction must be devised to solve the problem of internet addiction.

In this paper, we design a green supply chain (gSC) network model. For constructing the gSC network model, environmental and economic factors are taken into consideration in it. Environmental factor is to minimize the $CO_2$ emission amount emitted when transporting products or materials between each stage. For economic factor, the total cost which is composed of total transportation cost, total handling cost and total fixed cost is minimized. To minimize the environmental and economic factors simultaneously, a mathematical formulation is proposed and it is implemented in a genetic algorithm (GA) approach. In numerical experiment, some scales of the gSC network model is presented and its performance is analyzed using the GA approach. Finally, the efficiencies of the gSC network model and the GA approach are proved.
