The benthic environmental impact experiment addresses environmental impacts at a specific site related to deep-sea mineral resource development. We have acquired several tens of multi- or box core samples at 31 sites within the Benthic environmental Impact Site (BIS) since 2010, aiming to examine the basic properties of surficial deep-sea sediment as a potential source for deep-water plumes. In this study, we present the geochemical properties such as major elements, rare earth elements (REEs), and heavy metal contents at the BIS. Such proxies vary distinctly according to the Facies association. The lithology of all core sediments in the BIS corresponds to both Association Ib and Association IIIb. The vertical profiles of some major elements ($SiO_2$, $Fe_2O_3$, CaO, $P_2O_5$, MgO, MnO) show noticeable differences between Association Ib and IIIb, while others ($Al_2O_3$, $TiO_2$, $Na_2O$, and $K_2O$) do not vary between Association Ib and IIIb. REEs are also distinctly different for Associations Ib and IIIb; in Association Ib, REY and HREE/LREE are uniform through the sediment section, while they increase downward in Association IIIb like the major elements; below a depth of 8 cm, REY is over 500 ppm. The metal enrichment factor (EF) evaluates the anthropogenic influences of some metals (Cu, Ni, Pb, Zn, and Cd) in marine sediments. In both Associations, the EF for Cu is over 1.5, the EF for Ni and Pb ranges from 0.5 to 1.5, and the EF for Zn and Cd are less than 0.5, indicating Cu is enriched but Zn and Cd are relatively depleted in the BIS. The vertical variations of geochemical properties between Association Ib and IIIb are shown to be clearly different, which seems to be related to the global climate changes such as the shift of Intertropical convergence zone (ITCZ).

In the domestic construction industry, large-scale housing construction projects are being carried out by construction companies with competitiveness in the domestic top 10, it is said that the competence of the construction engineer is a factor for the success of the project. In Korea, there is National Competency Standards (NCS) that systematize contents of knowledge, technology, and attitude required in order to perform job in industrial field as the importance of individual ability is systemized in the country. Therefore, in this study, defined the detail competence in construction administration works, and examined the level of competence and degree of impotance detailed competency of construction engineers using AHP analysis & ANOVA. As a result, it was found that the current capacity of the Engineers in the apartment construction work is insufficient compared to the level of the competence they think they have, and that they have different competencies depending on their work experience and job position. This means that if the career is accumulated, the capacity that is possessed naturally will be changed. Therefore, it will be necessary to improve the capacity of the construction engineers who have a short work experience and a low job level.

Contrary to the fact that the old films contain artistic and include contemporary literature, religion, and philosophy, latest films are produced with focusing on external interesting composition and sensational scene. A good movie emotionally express the directors' topic message exuding from an interesting story, and empathize with the social agenda which shows a sharp look of the directors' on contemporary social aspect. In the movies of the Coen brothers, it seems like an entertainment movie as typical black comedy genre through irony and happening, but in fact, it inserts a lot of social problems in the film to show that they cynically express their social agenda from a contemplative view. In their movie "The Big Lebowski (1998)", it seems like they are creating comical content through the main characters' unaffected attitude. However, it is director's excellent director of the sub-text that expresses American social issues such as Vietnam war, post-modernism and an obscurantist policy and au fond the comedy about the historical facts of mass production of social maladjustment into black comedy. We expect to contribute to make a step forward in the Korea film industry by analyzing such movies that has the cultural power of influence.

Brad Bird, a screenwriter and animation director in the United States, criticized the situation in which most animations were produced and released for the children since the early 2000s. He said that animation is an art form capable of conveying messages not only to children but also to adults, and that their development potential is high. In this study, I analyzed overall components such as narrative structure, character, subplot, symbol, and foreshadow of Brad Bird's animated feature films , , and examined his narrative features and strategies. As a result, the narrative features of animation as an art form are as follows: First, conveying the message of a serious subject that will deeply sympathize with adults as well as children. Second, expressing the social agenda which criticizes the contradiction of the real world and the periodic mistakes. Third, solid narrative structure through a dense plot based on realistic situation setting. I hope that this study will be used as basic research material for various animation production in the future.

This study investigate the effect of each type of search volume on the number of Facebook fans and the number of tourists. According to the hierarchy effect model, the effect of communication appears to be the sequentiality of cognition-attitude-behavior. Applying this theory, this study predicted that when consumers who have higher involvement and knowledge on specific cities through search behavior, they will be more active in information search through Facebook fan page subscription and will lead to direct tourism behavior. To verify the prediction, we examined the influences among search volume of Seoul shown in Google Trend, the number of fans of official facebook page named 'Seoul Korea', and the number of foreign tourists. As a result, the type of search keyword was divided into four categories: tourism attraction keyword, natural environment keyword, symbolic keyword, and accessibility keyword. The regression analysis showed that tourism attraction keyword and symbolic keyword have influence on Facebook fanpage 'Like'. In addition, facebook fanpage fan size have mediation effect between search volume and number of tourists. All in all, it would be useful to appeal to foreign tourists with a message that emphasizes tourism attraction and Korea-related contents.

Christopher Nolan's film "Inception (2012)", which depicts the world of dreams as a unique space-time and opens a new chapter in the expression of dreams, portrays the dreamy world of unconsciousness. However, I can find limitations and contradictions in the expression of the actual dreams and essence of unrealistic structures and forms. I can find David Lynch's movies "Mulholland drive (2001)", which are closer to Freud's psychoanalysis in expressing the actual presentation process of dreams Through comparative analysis, I try to analyze the interpretation and context of the dream mentioned by Freud. The film "Inception" can be appreciated in terms of space time and rich imagination created from the point of view of science fiction movies, but it shows that logical reasonability is weak in view of applying the essence of dream. On the other hand, the film "Mulholland Drive" describes the illogical, confusing and unhappy feeling of unconsciousness by giving logic and order based on the interpretation of Freud's psychoanalytic dreams, is. In this way, it is possible to portray more realistic scenes of dreams only through the portrayal of dreams and unconsciousness based on Freud's psychoanalytic viewpoint.

Femvertising campaigns are more easily observed in oversea rather than in Korea. Most recently, not only global companies but local consumer goods companies launched several femvertising campaigns. However, no research was done on effects of femvertising in Korea. Thus, this study will explore Korean college students' understanding of, attitude toward, and effects of femvertising through focus group interviews. Study results found that college students have low level of understanding on the concept of femvertising. However, they are somewhat familiar with contents of femvertising. Femvertising is believed to have positive impacts on gender equality and female empowerment whereas there are growing concerns over commercializing feminism. Study participants, regardless of gender, suggest that femvertising could influence consumers' attitude toward advertising and brand, but they are skeptical of purchase intention. Lastly, female participants suggest that femvertising, compared to traditional advertising, will enhance attitude toward ads and brand, and even have a positive impact on feminism. However, male participants suggest that femvertising may exacerbate the gender conflict between males and females which is called as 'misandry' or 'misogyny'.

There has been much interest in the VWorld open platform with the addition of a variety of contents or services such as 2D map, 3D terrain, 3D buildings, and thematic map since 2012. However, the VWorld system architecture was not stable for the system overload. For example, the system was stopped due to the rapidly increasing user accesses when the 3D terrain service of the North Korea and the Baekdu mountain was launched at September 2012 and September 2013, respectively. It was because the system architect has just extended the server system and the network bandwidth whenever the rapid increase of user accesses occurs or new service starts. Therefore, this study proposes a new VWorld system architecture that can reliably serve the huge volume of National Spatial Data by applying the new technologies such as CDN, visualization and clustering. Finally, it is expected that the results of this study can be used as a basis for the next VWorld system architecture being capable of a huge volume of spatial data and users.
