This study investigates the characteristic spatial patterns and dynamic processes associated with the summertime extreme temperature events in South Korea during the last 20 years (1995~2014) using Self-Organizing Map (SOM). The classified SOM patterns commonly have high temperature and anticyclonic circulation anomalies over South Korea. The two major teleconnection patterns are identified: one is from the subtropical western North Pacific (WNP) affecting to the north and the other is from the North Atlantic (NA) affecting downstream region. The meridional teleconnection pattern is related to the forcing of positive sea surface temperature (SST) anomaly over the WNP. The northward propagating Rossby wave generates the East Asia-Pacific (EAP) pattern to form an anticyclonic circulation anomaly over South Korea. On the other hand, NA SST anomalies generate an eastward Rossby wave train across the Eurasian continent, leading to the development of an anticyclonic circulation anomaly over South Korea. The EAP pattern occurs more frequently in July and August, whereas the midlatitude teleconnection pattern associated with NA SST anomalies develops more frequently in early summer (June).

The zooplankton community and environmental factor were investigated on a weekly basis from March to November 2015 in Lake Paldang, Korea. The seasonal succession of zooplankton community structure was influenced by hydraulic and hydrological factors such as inflow, outflow and rainfall. However, the hydraulic retention time in 2015 (16.3 day) was affected by the periods of water shortage that had continued since 2014 and increased substantially compared to 2013 (7.3 day). Therefore, the inflow and outflow discharge were decreased, and the water quality (COD, BOD, TOC, TP, Chl-a) of Lake Paldang (St.1) was the same characteristics as the river type Bukhan river (St.3), compared with the lake type Namhan river (St.2) and Gyeongan stream (St.4). Zooplankton community dominated by rotifers (Keratella cochlearis, Synchaeta oblonga) in spring (March to May). However, Copepod (Nauplius) and Cladoceran (Bosmina longirostris) dominated in St.4. In summer (June to August), there was a few strong rainfall event and the highest number of individuals dominated by Keratella cochlearis (Rotifera) and Difflugia corona (Protozoa) were shown during the study period. In autumn (October to November), the water temperature was decreased with decrease in the total number of individuals showing Nauplius (Copepoda) as the dominant species. As a result of the statistical analysis about zooplankton variation in environmental factors, the continuous periods of water shortage increased the hydraulic retention time and showed different characteristic for each site. St.1, St.3 and St.2, St.4 are shown in the same group (p<0.05), showing the each characteristics of river type and lake type. Therefore, the water quality of catchment area and distribution of zooplankton community would be attributed to hydraulic and hydrological factors.

Hojil(虎叱) and Yangbanjeon(兩班傳) reveal the characteristic styles of Park Jiwon(朴趾源)'s writing, which is combining styles of unofficial history/biography(外傳) and allegory(寓言), and full of the senses of satire and humour which form another characteristc of his writing style or tone. This paper reexamines narrative styles, meaning structures and themes of these two works which combine the styles of unofficial history/biography and allegory, and researches methods and techniques of allegory and satire which presents the subversive and critical themes and thoughts of the author. In Hojil, combining of the two styles, the author constructs the narrative world and plot, manipulates allegoric figures to symbolize and present multilayered meaning, and criticize the decadence of confucian aristocracy [Sadaebu: 士大夫] and it's abuses. In Yangbanjeon by combining of two styles, the author weave a biography of Yangban(兩班) in general, which presents the attributes and historical position of the Yangban class. And by the nonsensical fictional event which caricatures crisis of the Yangban class, and tedious description of the manners and behaviors of the Yangban, the author and satires the snobbery of the Yangban and the absurdity of their classical privileges. As he did in Hojil, the author urges the self-examination of the reader raising a question about the position and the function or duty of the Yangban class in the changing world. And the various skills of satire together with the irony, paradox, parody and pun were used dexterously in above two works.

This study investigated the meaning of absolute music of the first movement of Brahms' symphony No. 1, which was used as film music in the films "Tetro" and "Savages" and interpreted the meaning of this music used in these two films. Therefore, the purpose of this study is to explore the characteristics that classical music can be interpreted ambiguously in films. In particular, it was examined whether film music could be interpreted in a new meaning rather than a program music. The first movement of Brahms' symphony No. 1 is in a sonata form and has the characteristics of a chromatic grammar of the romanticism. In "Tetro", the irony about the value connection between this music and the characters of the film, the composition process of this music and the historicity that appeared in the character story of the film presented important. On the other hand, in "Savages", the chromatic grammar of this music expresses the emotional meaning of the characters in the film and the atmosphere of the event. This can be said to be the role of program music. In particular, the scene in which this music is used at the end of "Tetro" shows an ambiguous characteristic that can interpret a piece of music in different meanings depending on which of the two characters appearing in the film interprets the music from the perspective of the character. And the fact that Brahms spent 21 years to complete this music and that Tetro, the main character of the film, spent about 10 years before going through theatrical scenario and submitting it to the festival in the film, coincide with each other in terms of historicality. This gives the meaning of understanding film music from a new point of view, not from the point of view of absolute music or program music. In addition, this musical setting made the music recognized as an essential element of the film and as an irreplaceable auditory theme. When classical music meets other art such as film, this ambiguity Characteristics of music will have a great influence on the new perception of classical music.

It is a rising trend that the number of users using one of the social media channels, the Social Network Service, so called the SNS, is getting increased. As per to this social trend, more companies have interest in this networking platform and start to invest their funds in it. It has received much attention as a tool spreading and expanding the message that a company wants to deliver to its customers and has been recognized as an important channel in terms of the relationship marketing with them. The environment of media that is radically changing these days makes possible for companies to approach their customers in various ways. Particularly, the social network service, which has been developed rapidly, provides the environment that customers can freely talk about products. For companies, it also works as a channel that gives customized information to customers. To succeed in the online environment, companies need to not only build the relationship between companies and customers but focus on the relationship between customers as well. In response to the online environment with the continuous development of technology, companies have tirelessly made the novel marketing strategy. Especially, as the one-to-one marketing to customers become available, it is more important for companies to maintain the relationship marketing with their customers. Among many SNS, Facebook, which many companies use as a communication channel, provides a fan page service for each company that supports its business. Facebook fan page is the platform that the event, information and announcement can be shared with customers using texts, videos, and pictures. Companies open their own fan pages in order to inform their companies and businesses. Such page functions as the websites of companies and has a characteristic of their brand communities such as blogs as well. As Facebook has become the major communication medium with customers, companies recognize its importance as the effective marketing channel, but they still need to investigate their business performances by using Facebook. Although there are infinite potentials in Facebook fan page that even has a function as a community between users, which other platforms do not, it is incomplete to regard companies' Facebook fan pages as communities and analyze them. In this study, it explores the relationship among customers through the network of the Facebook fan page users. The previous studies on a company's Facebook fan page were focused on finding out the effective operational direction by analyzing the use state of the company. However, in this study, it draws out the structural variable of the network, which customer committment can be measured by applying the social network analysis methodology and investigates the influence of the structural characteristics of network on the business performance of companies in an empirical way. Through each company's Facebook fan page, the network of users who engaged in the communication with each company is exploited and it is the one-mode undirected binary network that respectively regards users and the relationship of them in terms of their marketing activities as the node and link. In this network, it draws out the structural variable of network that can explain the customer commitment, who pressed "like," made comments and shared the Facebook marketing message, of each company by calculating density, global clustering coefficient, mean geodesic distance, diameter. By exploiting companies' historical performance such as net income and Tobin's Q indicator as the result variables, this study investigates influence on companies' business performances. For this purpose, it collects the network data on the subjects of 54 companies among KOSPI-listed companies, which have posted more than 100 articles on their Facebook fan pages during the data collection period. Then it draws out the network indicator of each company. The indicator related to companies' performances is calculated, based on the posted value on DART website of the Financial Supervisory Service. From the academic perspective, this study suggests a new approach through the social network analysis methodology to researchers who attempt to study the business-purpose utilization of the social media channel. From the practical perspective, this study proposes the more substantive marketing performance measurements to companies performing marketing activities through the social media and it is expected that it will bring a foundation of establishing smart business strategies by using the network indicators.
