Recently, Due to the rapid growth of broadcasting communication and video coding technologies, the demands for immersive media contents based on 3D stereoscopic video will increase steadily. And the demands must ultimately provide the contents for users which are in wireless channel such as vehicle, train, and ship. Thus, in this paper, we transmit the 3D stereoscopic video over the maritime Rician channel that direct wave is more dominant than reflective wave. Besides, we present unequel error protection (UEP) by applying hierarchical 4/16-QAM to V+D(Video plus Depth) format which can represent 3D stereoscopic video. We expect our system to provide seamless broadcasting service for users with poor reception condition.

The uptake of germanium(Ge) by health foodstuffs was interesting because of a therapeutic effect of organic germanium. Germanium contents in different plant parts of the cultivated Korean Angelica keiskej Koidz in several growing districts were determined by square wave anodic stripping voltammetry. Experimental conditions in germanium determination from Angelica kejskej Koidz were as follows : deposition time; 20 sec, deposition potential; -0.9 volts vs Ag/AgCl, and frequency; 100 Hz in 0.1M\;HClO_4, supporting electrolyte solution at pH 2.43 containing $1.5\;{\times}\;10^5\;M$ pyrocatechol violet. Calibration curve showed a good lineality in the range of 0.4 ppb to 2.0 ppm and the detection limit was 0.08 ppb. There was a large difference in content according to growing districts ranging from 102 to 386ppm. Germanium content in leaf parts was much higher than that in stems.

The purpose of this study is to analyze how Chinese people perceive the acceptance and spread of Korean popular culture through the analysis of the Korean Wave news frame in Chinese daily newspapers. The result of analysis showed that there was a significant difference in the number of an article appearance in all three daily newspapers by year according to a specific issue including the popularity of Korean Wave-related events, Korean dramas, movies and Korean stars. This reporting trend also appeared in the article format, and all three daily newspapers mainly used an episodic frame to deliver fragmentary Korean Wave trend or personal information emotionally rather than a thematic frame to analyze and interpret the Korean Wave trend in depth. As a result of analyzing dominant news frames using the inductive approach to examine specific contents of the articles, news frames that composed the Korean Wave into the cultural interest frame as 'Interest and attention toward Korean popular culture' and gave positive evaluations were dominant, followed by the economic news frames that explained the Korean Wave from the economic perspective and the political news frames that considered the Korean Wave from the viewpoint of the Chinese Government. These news frames appeared somewhat different according to the publishing purpose of daily newspapers. ${\ll}$People's Daily${\gg}$ which is the official organ of the Chinese Communist Party often covered the political frames to report the policies of Chinese government, ${\ll}$People's Daily (Overseas edition)${\gg}$ often covered economic frames from the overseas perspective and the Jinghua Daily which is a commercial newspaper by nature often handled cultural interest frames to consider Korean Wave as new cultural phenomenon.

Abstract Over 700/0 of the rural land area in Korea is mountainous and small watersheds provide most of the water resources for agricutural use. To provide an appropriate tool for the agricultural water resource development project, SNUA2, a mathematical model for simulating the physical processes governing the precipitation-runoff relationships and predicting the storm and long-term runoff quantities from the small mountainous watersheds was developed. The hydrological characteristics of small mountainous watersheds were reviewed to select appropriate theories for the simulation of the runoff processes, and a deterministic and distributed model was developed. In this, subsurface flows are routed by solving Richard's two dimensional equation, the dynamics of soil moisture contents are simulated by the consideration of phenological factors of canopy plants and surface flows are routed by solving the kinematic wave theory by numerical analysis. As a result of an application test of the model to the Sanglim watershed, peak flow rates of storm runoff were over-estimated by up to 184.2%. The occurence time of peak flow and total runoff volume of storm runoffs simulated were consistent with observed values and the annual runoff volumes were simulated in the error range of less than 5.8%.

In this paper, it is presented a level sensor for measuring a level of the contents of cargo tank using frequency modulated continuous wave(FMCW). The frequency range is 10∼11 GHz, the radar cross section(RCS) of target is 0.8 ㎡ of metal plate. the experiment is performed in laboratory and open ground, the sweep time of the signal is 100 ms, the pyramidal horn antenna of about 20 dBi gain is used, and input power of antenna is about 5 dBm. the beat frequency according to the target moving to 40 m is measured. There is a good agreement between measured and calculated results. But the resolution of the FMCW radar is measured about 10 cm due to nonlinear of voltage controlled oscillator(VCO).

The effect of co-sputtering condition on the structural properties of $Mg_xZn_{1-x}O$ thin films grown by RF magnetron co-sputtering system was investigated for manufacturing ZnO/MgZnO structure LED. $Mg_xZn_{1-x}O$ thin films were grown with ZnO and MgO target varying RF power. Structural properties were investigated by X-ray diffraction (XRD) and Energy dispersive spectroscopy (EDS). The ZnO thin films have sufficient crystallinity on the high RF power. As RF power of ZnO target increased, the contents of MgO in the $Mg_xZn_{1-x}O$ film decreased. LED was manufactured using ZnO/MgZnO multi-layer on p-GaN/$Al_2O_3$ substrate. Threshold voltage of multi-layer LED was appeared at 8 V, and it was luminesced at wave length of 550 nm.

Young Chinese audience can select and watch TV dramas, movies and entertainment programs from many different nations, such as Korea, America, Japan, England, Thailand, India, and so on, through multiple channels, such as online video sites - iQiyi, Youku, LeTV, PPTV, and many others - which were induced by changes in media environment. Various genres of Korean popular culture have recently become popular in China, but this phenomenon differs from the early Korean Wave. During the earlier period (from 1997 to the early 2000s) of the Korean Wave, soap operas were popular among middle-aged women, but now various other genres, such as K-pop, entertainment programs, etc., are also popular in China. The purpose of this study is to explore how young Chinese audiences use foreign pop culture, including their preferred genres, reasons for preferring these genres, and the relationship between the preferred pop culture and national image in Korean, American, and Japanese pop culture were analyzed. According to the study results, similarities and differences between preferred genres and the reasons for preferring these genres, and also a close correlation between preferred pop culture and national image were found. These findings will be fundamental for supporting the continual development of the Korean Wave in China.

This dissertation is to seek new valuable possibility of the 100 best Chinese films on storytelling in Chinese films as considering about content development of Korea and China's Collaborative film production and extension, that being magnified as a new content for variety of Korean film production. The moment to the Korean wave is getting cold in Japan, Korean wave is attempt to receive attention in new field through China by various image field with Korean drama's appeal. However, film content fall short of our expectation than media content, even if supporting much various attempts with Korea and China's Collaborative film production content. Specially, there are not satisfied films for Korea and China both counties's audience, although Korea and China's Collaborative film production has been produced steadily. The writer studies on stories of Chinese essential 100 films for searching deeply this problem. Among them, in selected 'The 100 Best Chinese Films' by China in 2005, films in 1930's are selected as the first step to study, and this dissertation searches to communicate storytelling's meaning in Chinese films through that time image. This studies what is the point of selected story by China, and there are what kind of worries. This dissertation considers that focused on characters, event and background. Chinese film in 1930's represented life in times through process of play development that is connected with poverty, reality of society, death, tragedy and tragicomedy.
