This study aims to consider the effects of the change in communication culture affected by 'Social Media' on the film marketing. Particularly, Twitter, a kind of Social Media which shows the most rapid growth recently, is examined for what kind of benefits it's functional characteristics would provide for film marketing. Twitter, which has distinctive characteristics such as free access, the high level of attention resulting from its simplicity, alarming speed of spreading information and low costs, offers a variety of marketing opportunities not only for general commercial films but for low budget or independent films that do not have sufficient marketing opportunity. In the case of the documentary film (2010, Woo-jung Kwon), starting from the process of the film production through release to the time after the screening, it continued to communicate with potential audiences via Twitter and tried every tool of film marketing like advertising, PR, promotion and word of mouth. By doing so, it provides a model for low budget or independent films about what alternative activities they might be able to conduct for film marketing.

Today seafoods, such as fisheries and clams, have become an important part of our diet. But processing and storing these perishable seafoods for a long period of time present a serious problem. Only a few years ago, the seafood consumption was minimal. However, an improvement in our diet has enabled us to enjoy seafoods more often than before. Moreover, the recent trend toward the concentration of the popuration to the metropolitan area and the improvement in the standards of living have accelerated a change in our food consumption pattern-preference for the convenient foods over time consuming cooking. Judging from these changes, we can easily predict that the demand for the covenient, dried seafoods will rise sharply in the coming days. The development for an innovative and attractive way to package and market these products are on the way. Research and development of the distribution channel and package design of the dried seafoods will offer a wide array of opportunities to increase the sales volume of the dried seafoods. In addition, by associating the image of Pusan, as a prime oceanic city, with the dried seafoods on the package will certainly draw the attention of many prospective consumers. Consequently it will make the dried seafoods special products of Pusan, and eventually contribute to the prosperity of the city.

One of 21st century's main paradigms is a 'Culture', and people started to express their 'cultural desires and demands' regarding public environments. Accordingly central and local governments are paying attention to these demands from their citizens and trying to establish the policies to meet these needs. This research is done to suggest the strategy programming model to support the executions of culture-centered public designs which are based on the local resources and identities. The entire research contains three sub-topics. First topic is setting the prototype phases of strategy programming. Second topic is analyzing the associated indices for each prototype phase. Third topic is suggesting Matrix Model in which the prototype phases and their associated indices are linked. Among three topics, this paper deals with the first one - the prototype phases of strategy programming. It studies this subject in relation with Place Marketing which emphasizes the local resources and identities. The prototype phases are comprised of 3 steps for Place Strategy and 4 steps for Marketing Strategy. Place Strategy should be considered prior to Marketing Strategy because in culture-centered public design, locality has priority over other concerns. The phases for Place Strategy includes 'Resource_analyzing of local resources', 'Mission_setting a purpose', and 'Targeting_segmenting target groups'. The phases for Marketing Strategy involves 'Organization_instituting the main body and/or partnership', 'Image Positioning_setting an unique local image', 'Point_realizing the product', and 'Channel_deciding the sales promotion tools'.

Hydrographic survey in the Korea Strait has long history that has begun in August 1917 at the Busan - Tsushima cross section, still continues to date. However, chemical properties of bottom cold water found exclusively in the western channel of the Korea Strait during summer did not receive much scientific attention. The aim of the study is to decipher the enigmatic origin of the Korea Strait Bottom Cold Water (KSBCW) in terms of chemical properties. The physicochemical properties of the KSBCW are extracted from the CREAHS II hydrographic data. OMP method was applied to analyze origin of the KSBCW quantitatively. The KSBCW is well defined by low temperature below $10^{\circ}C$. The cold waters exhibited the local presence near the coast at about 120m depth with a thickness of 20m to 30m. The cold water was characterized by relatively cold, saline and higher chemical concentrations than adjacent waters. The KSBCW seems to have different origin kom that of the coastal upwelled waters at the Ulgi-Gampo because it is saline, denser and contains considerably less dissolved oxygen than upwelled waters. The physicochemical properties are reported to have noticeable annual variations which suggest the complex origin of the KSBCW. OMP analysis show that the KSBCW is a mixture of three water types; TMW (24%), ESIW (36%) and ESPW (40%). Relationship between the KSBCW and the east Sea circulation is traced by mapping the water masses that have similar T, S and DO of KSBCW. The result showed that the KSBCW is most possibly an extension of southward flowing coastal intermediate waters. Front these results, we expect that the monitoring KSBCW will provide us valuable information about the East Sea circulation.

The growing socio-economic effect caused by science and technology requires public to participate in policy-making process, which makes government to boost public understanding of science(PUS). Government has also exerted to construct infra for PUS. However results are not so meaningful. The government-funded science museum has mainly provided the program for students. Besides, science broadcasting channel has recorded the worst viewing rate. Meanwhile, some of the private sector-manufactured contents have attracted public attention in recent years, which is realized by considering elements such as an interesting topic selection, use of outside experts, two-way communication system, level adjusting for public through flexible running system. This study analyze podcast based program, face to face lectures, display contents by private industry, fab lab etc. on the base of the reciprocal PUS model to sort out the reason they have successful results. Futhermore, it argues that government should intensify support for private sector and create synergy effect by cultivate collaboration system between government and private sector to enhance the efficiency of PUS and offers public policy to realize the plan.

Recently, YouTube's growth started drawing attention. YouTube is not only a content-consumption channel but also provides a space for consumers to express their intention. Consumers share their opinions on YouTube through comments. The study focuses on the text of global entrepreneurs' speeches and the comments in response to those speeches on YouTube. A content analysis was conducted for each speech and comment using the text mining software Leximancer. We analyzed the theme of each entrepreneurial speech and derived topics related to the propensity and characteristics of individual entrepreneurs. In the comments, we found the theme of money, work and need to be common regardless of the content of each speech. Talking into account the different lengths of text, we additionally performed a Prominence Index analysis. We derived time, future, better, best, change, life, business, and need as common keywords for speech contents and viewer comments. Users who watched an entrepreneur's speech on YouTube responded equally to the topics of life, time, future, customer needs, and positive change.

The main objective of this study was investigation of natural gas flames in a lean premixed swirl-stabilized dump combustor with an attention focused on the effect of the various fuel-air mixing section geometry on the combustion instability characteristics. The multi-channel dynamic pressure transducers were located on the combustor and inlet mixing section region to observe combustion pressure oscillation and difference phase at each dynamic pressure measurement results. Dynamic pressures were also measured to investigate characteristics of combustion at the same time. The combustor and mixing section length was varied in order to have different acoustic resonance characteristics from 800 to 1800 mm in combustor and 470, 550, 870 mm in mixing section. We observed two dominant instability frequencies in this study. Lower frequencies were obtained at lower equivalence ratio region and it was associated with a fundamental longitudinal mode of combustor length. Higher frequencies were observed in higher equivalence ratio conditions. It was related to secondary longitudinal mode of coupled with the combustor and mixing section. In this instability characteristics, pressure oscillation of mixing section part was larger than pressure oscillation of combustor. As a result, combustion instability was strongly affected by acoustic characteristics of combustor and mixing section geometry.

The professional duties of librarians and other information workers involve a generalized body of both theoretical and practical knowledge (the so-called, 'common core') which is a n.0, pplicable worldwide without regard to national boundaries, levels of economic and technical development or cultural context. The current study is an attempt to validate and su n.0, pport this common core concept through a detailed examination of its important role in the sound development of library and information science both as a learned subject and as a profession. Following an initial overview of generally agreed upon core areas in the education and training of librarians and information specialists, with particular attention to the manifold social changes rapidly being effected by computers and communication technology, the focus shifts to the proliferation of academic homes for information science education and its implications for core areas in information science. Of note here is the relationship between information science as a broadly accepted social science discipline and the evolving core curriculum in library schools. To this regard the fact that the popularization of computers and communication technology is increasingly blurring the once-sharp differences between traditional librarians and information specialists naturally favors common core concept. Major figures in library and information science education such as Shera, Saracevic and Foskette su n.0, pport this concept and have already identified its theoretical infrastructure. Finally, UNESCO and IFLA are also stressing the common core cure curriculum for library and information science both as guidelines for the Third World and as a means to achieve universally accepted academic standards. In conclusion, the search for a comprehensive common core curriculum in library and information science education is still in the elementary stages. The task of identifying the components of this common core is among the most crucial responsibilities facing today's educators and professionals for the successful elaboration of a common core would enable us to attain three highly desirable professional goals: 1) To determine the basic concepts and principles of library and information science. 2) To serve as the base for further professional education and specialized research. 3) To offer enhanced o n.0, pportunities for integrated library and information science education programs by providing a genuine two-way communication channel between the library and information science professions.

Recently, as required wireless communication traffic increase, millimeter wave mobile technologies that can secure broadband spectrum are gaining attention. However, the path loss is high in the millimeter wave channel. Massive MIMO system is being researched in which can complement the path loss by beamforming by equiped large-scale antenna at the base station. While legacy beamforming techniques have analog and digital methods, practical difficulties exist for application to massive MIMO systems in terms of system complexity and cost. Therefore, this paper studies a hybrid beamforming scheme for massive MIMO system in the millimeter wave band. Also this paper considers spatial multiplexing scheme to serve multi-users with multiple received antennas. Gains of the beamforming and the spatial multiplexing schemes are evaluated by analyzing the spectral efficiency.

Recently much attention has been devoted to femtocell's potential to improve indoor cellular coverage and high speed wireless communications. Femtocell based commercial services have been already launched in some countries and standardization activities are actively on-going, there has been concern however over potential issues of interference between femtocells and the micro/macro networks. With universal frequency reuse, the ensuing cross-tier interference causes unacceptable data rate and outage probability, so an analysis of effect of interference in femtocell embedded networks would be necessary for a stable system design. This paper investigates the effect of interference on system performances of femtocell embedded hierarchical cell structure (HCS) networks considering the characteristics of propagation environments. Various channel parameters are specially considered for indoor environments where most of femtocells are deployed to investigate the effect of interference of femtocell embedded RCS networks. System capacity and coverage are provided with variant distance between macrocell and femtocell, location of the user in femtocell coverage, and characteristic of building structures.
