With the advent of the age of the 4th Industrial Revolution, countries around the world are reinforcing informatics education to cope with changing society. The purpose of this study is to analyze the trends in German informatics education through the analysis of the German informatics curriculum, and provide implications for the informatics education of Korea. The analysis of German informatics education focused on the contents and changes of the informatics education of Bayern, which can be said to be the center of German education. As a result of this analysis, first, elementary education approaches 'informatics' from the viewpoint of integrated curriculums. Second, secondary education provides education that makes it possible to experience theory and practice by securing sufficient credit hours. Third, they reflected informatics subjects in entrance examinations, and sufficiently ensured links to higher education.

The purpose of this study is to compare a supposedly "pot boiler", Sanctuary and Sanctuary: The Original Text and examine the fact that Horace Benbow in The Original Text is a more complicated and many-sided character who has suppressed desire, Oedipus complex, sense of guilt for a long time, until he came to confront Temple-Popeye case. Since literary narration means unconscious procedure, Horace's incestuous love for his step daughter and Oedipal relation reveals Faulkner's own psychology. In this sense, The Original Text serves as a matrix of many of Faulkner's major novels in terms of themes, characters, and the relationship between past and present. Among these novels are The Sound and the Fury, As I Lay Dying, and Flags in the Dust. Faulkner, while writing about his own world creating Yoknapatawpha County, tries to portray characters with artistic value through whom he wanted to express the deep anxiety and turmoil of the 1920s. Starting with Horace Benbow, Quentin Compson, Darl Bundren and young Bayard Sartoris can be doubling through his major works, conveying author's profound despair in the context of modern world.

A battle royale game is a multiplayer video game genre that blends the survival and exploration with last-man-standing gameplay. The genre has been hot in recent years and the 'Player Unknown's Battleground' produced by Korean enterprise PUBG had been the hottest during 2017 and the first half of 2018. However, a similar battle royale game 'Fortnite' became the game of the year in 2018 and the Player Unknown's Battleground sustains the predominance only in Korea and China. In this paper, we investigate the game structure of those two games on combat, survival, farming and charging elements, We also conduct a user survey on what might be the weak point of the Player Unknown's Battleground and why they choose Fornite among users played both but currently play Fortnite. The result shows that the Player Unknown's Battleground sustains the advantage on battle elements but creative charging policy and the efficient survival elements are the reasons of choosing Fortnite between the two.

Organic farming is necessary to sustainable agriculture, preserve biodiversity and continued growth the sector in agriculture. In organic farming, reduced usage of chemical agents that adversely affect human health and environment, employing amino acids and oil cake fertilizer, plant extracts, and microbial agents are used to provide safe agricultural products to consumers. To investigation microbiome structure, we proceeded on the pepper plant with difference fertilizers and treatments in organic agriculture for three years. The microbial communities were analyzed by the next generation sequencing approach. Difference soil microbiota communities were discovered base on organic fertilizer agents. Occurrences of virus and anthracnose diseases had a low incidence in conventional farming, whereas bacteria wilt disease had a low incidence in microbial agents treated plots. Microbe agents, which applied in soil, were detected in the microbial community and the funding suggested the applied microbes successfully colonized in the organic farming environment.

Where should a plant or service facility be located? The decision is crucial since the capital investment in land, factory construction, and facility is enormous. Once a firm has sunk a large sum of money into a factory, it lives with the decision for a long time. In this age of global markets and global production, this is a key decision problem for contemporary manufacturing and/or service. Using data from Korean and Chinese managers and the AHP (Analytic Hierarchy Process), this paper did study on the actual condition for identifying the differences of opinion between the two group's(Shanghai and Shenyang managers) in how to make decisions on the location problems. Since this study was carried out during recent global economy recession, and the limitation of the collected questionnaires, it is hard to avoid the possibility for those managers to show different view from their ordinary times. Nevertheless, this paper will provide managers with useful informations on successful facility location in China.

Among the various security threats in online games, the use of game bots is the most serious problem. In this paper, we propose a framework for user behavior analysis for bot detection in online games. Specifically, we focus on party play that reflects the social activities of gamers: In a Massively Multi-user Online Role Playing Game (MMORPG), party play log includes a distinguished information that can classify game users under normal-user and abnormal-user. That is because the bot users' main activities target on the acquisition of cyber assets. Through a statistical analysis of user behaviors in game activity logs, we establish the threshold levels of the activities that allow us to identify game bots. Also, we build a knowledge base of detection rules based on this statistical analysis. We apply these rule reasoner to the sixth most popular online game in the world. As a result, we can detect game bot users with a high accuracy rate of 95.92%.

As the game industry grows, the companies are promoting price discounts to increase game sales and profits. Consumers generally feel guilt when they are purchasing games. Previous studies argue that consumers feel less guilty and justify their consumption more easily when they are purchasing hedonic products at discounted price. In this study, we argue that there are different types of games; multi-game where consumers socialize each other and single games not supporting socializing. In the multi-game, consumers make social relationship which can provide substantial benefits. Since multi-games are promoting consumers' socializing expected to have those benefits. Although most of game consumptions bring a sense of guilty feeling, purchasing multi-game may not cause guilt much because the benefits of socializing justify the consumption. To support my hypothesis, we collect the data from global game platform Steam to analyze the relationship between price promotion and number of consumers. As a result, price promotion has significantly different relationship between multi-and single game. The results of this study suggest several managerial implications.
