This study reduced real-time image size using bilinear interpolation. First, calculate the ratio of the size of the original image and the image to be reduced to obtain the corresponding coordinates. After, calculate pixel intensity of the coordinates using the adjacent coordinate pixels of the calculated coordinates. Process time of the calculate process is reduced by using parallel-processing. Also, same calculation was processed on the CPU and compared with the results of the parallel processing on the FPGA.
『두공부시범덕기비선 杜工部詩范德機批選』의 한중 판본과 그 계통
黃瑄周(Hwang, Seon-joo) 중국어문학연구회 2015 중국어문학논집 Vol.0 No.92
Based on the Chinese edition in Yeonsei university, we have four Korean editions of Dugongfushifandejipixuan(杜工部詩范德機批選). Korean editions, which lost meaningful script about the publishing, do not have clear proof of date, we can discern each other Korean editions on reliable clue. The first Korean edition was published in 1410(大聖庵本), second edition in 1501(首爾大本), third edition in 1528(延世大本), the last edition in 1550. This selection of Dufu(杜甫)‘s poetry could be published by the ruling class who agree the policy of government. Chaoxian(朝鮮) regime tried to establish the nation of Confucius thought, and Dufu was a most appropriate poet for that urgent purpose.

There are so many CCTV in our streets, buildings and public places. Nevertheless, security methods for CCTV are rarely. This paper describes a study on developing a media crypto algorithm for anti-hacking into CCTV. H.264 codec is used to compress the video stream in CCTV systems. HIGHT algorithm provided by KISA is adopted as a crypto algorithm in our development. Other crypto methods except HIGHT could be selected by company’s security police. Only some bytes in VCL(Video Coding Layer) of H.264 are encrypted to improve the performance of limited platforms, such as CCTV, WebCam, smartphone. Very fast and light crypto algorithm was developed by our researches.

The funtion of complementary verb "去‘ in Jikji(直指) are as follows. 1. It is the direction of primary verb such as, in "隨去‘ etc. 2. It is the completion of movement such as, in "悟去‘ etc. 3. It is the duration and future of movement such as, in "上石去‘ etc. 4. It is the imperative of movement such as, in "洗鉢盂去‘ etc. ‘去‘ as the completion of movement is most frequent, but we cannot discover the similar cases in modern Chinese. The imperative of movement in ’去‘ is the conclusion of my personal view and it is necessary to prove such function in the nearly future.
무엇이 국가의 수출입을 결정하는가?: 주요 선진국의 무역에 대한 실증적 분석
황호선 ( Ho Seon Hwang ) 한국세계지역학회 2011 世界地域硏究論叢 Vol.29 No.2
이 논문은 주요 선진국들의 수출입의 가격 및 소득탄력성의 상대적 크기를 추정하여 무역에서의 가격과 소득변화의 상대적 중요성을 평가하려 한다. 선형회귀분석의 결과, 선진국들의 무역에서 3가지 특징적 형태가 발견되어진다. 첫째, 상대가격의 변화가 무역에 미치는 효과는 적은 것으로 나타났다. 둘째, 소득변화가 가격변화에 비해 무역에 대해 더 큰 영향을 미치는 것으로 나타났다. 이러한 실증추정의 정책적 함의로는 평가하락보다는 비가격경쟁력의 향상이 무역수지개선을 위한 효과적인 수단이라는 것을 나타내고 있다. 셋째, 선진국 간의 무역불균형과 불균형에 대한 긴축조정의 본원적 경향이 존재하며, 그로 인하여 선진국 전체의 경제성장에 대한 하락압력이 존재한다. 이러한 무역불균형과 긴축조정에 대한 본원적 성향은, 현재 진행 중인 세계경제위기의 극복과 아울러, 선진국들이 해결해야 할 지난한 과제를 던지고 있다. This paper tries to evaluate the relative importance of price changes to income changes in a nation`s trade by examining the relative sizes of price and income elasticities of exports and imports of major industrial countries. After applying linear regression estimation (autoregressive distributed lagged model), the paper finds three distinctive features of the trade of industrial countries. First, relative price changes have little effect on trade. Secondly, income changes have a dominant effect on trade over price changes. The policy implication of the estimation results is that currency depreciation cannot be an effective measure to improve trade performance of those countries. The improvement in a country`s non-price competition may be the only solution to better trade performance. Thirdly, there is an intrinsic tendency of both a persistent trade imbalance among industrial countries and deflationary adjustment to trade imbalance, which in turn exerts a heavy downward pressure on economic growth of the whole industrial world. The tendency of both trade imbalance and consequent deflationary pressure of economic growth may put forward one of most challenging tasks that the industrial world has to get through together with overcoming the current crisis of the world economy.

Nakdong river in the modern literature is the place which reveals the contradiction of the social structure. This place also brings the keen confrontation of opposite classes. In addition, this is the headquarter of lives and endless conflicts under the pretense of development. The distorted oppression of power, resulting from the contradiction of the modern society, has its own way in this area. And this is the sorrowful space in which the real space of the people has been taken away from the inside oppression.<BR> The contradiction becomes profounder because the unjust modern order and doctrine of the Japanese occupation by force has been connected until now. Everyone knows that this is unfair, but nobody tells this officially. And the isolated class have been separated from the indifferent social environment in this place. Because of the continuance of the modern chaos condition, our contemporary history lose its path, which has been the unsolvable problem.<BR> Nakdong river in the novels of Jo, Myeong-Hui and Kim, Jeong- Han is the fighting space and in the poetry of Kim, Yong-Ho, this is the floating contemporary space which keeps picturesque past recollection. Nakdong river as a tragic place puts down its root as another place in which the lives of the people are sung through the Folk Song[Minyo]. The collective lives shown into the Folk Song are the vestige of the post-modernity society surrounding Nakdong river. The people overcome the contradiction of the modern society through the Folk Song and open a new life space.<BR> Finally, the sequential poem ‘A Song of Water’ written by Lee, Dong-Soon shows a new life prospect of the people through the submerged districts in the industrialized age. This feature shows the direction which has a tendency to deviate from the modernity. And this intend to the post-modernity.<BR> Since the modern age, Nakdong river has been the place of endless conflicts, and fighting and remains as an alternative new place. In the contemporary age in which people overcome the distorted modern society and intend to the post-modernity, literary texts surrounding Nakdong river which are more adventurous and active should be produced. Also, this is another task which our modern literature should intend to.
