To see the implication of trade policy in endogeneous growth model, we introduce trade protection that takes the form of an import tariff and represents one plus the rate of protection provided to industry sector. We showed that considering goodness of fit of regression model, we can see that the empirical evidence is strongly in favor of the character of trade policies as the instrument spurring economic growth. As for import tariff, we see that 1% increase in the rate of tariff that protect domestic market causes the rate of growth to increase by 0.87%. An import tariff to final product significantly spurs product development and faster growth come as a result. But, we should note that the effects of trade policy are muted by the induced changes in the output of intermediates in an economy that is relatively unproductive in the research lab.

All bearing device should be examined to determine that they are functioning properly. Small changes in other portions of the structure, such as pier or abutment settlement, may be reflected in the bearings. Bearings should be checked to see that they can move freely and are clear of all foreign material. Shoes should be in proper position relative to the temperature at the time of the inspection. Check anchor bolts for any damage and to see that nuts are secure. See that anchor bolt nuts are properly set on the expansion bearings to allow normal movement. In this paper, rehabilitation method for damaged bearings is proposed and damage example of the skewed bridge is illustrated

By using the concept of intuitionistic interval-valued fuzzy sets, we introduce the notion of intuitionistic interval-valued fuzzy topology. And we study some fundamental properties of intuitionistic interval-valued fuzzy topological spaces: First, we obtain analogues[see Theorem 3.11 and 3.12] of neighborhood systems in ordinary topological spaces. Second, we obtain the result[see Theorem 4.9] corresponding to "the 14-set Theorem" in ordinary topological spaces. Finally, we give the initial structure on intuitionistic interval-valued fuzzy topologies[see Theorem 5.9].

A Weyl type algebra is defined in the paper (see [2],[4], [6], [7]). A Weyl type non-associative algebra $\bar{WN_{m,n,s}}$ and its restricted subalgebra $\bar{WN_{m,n,s_r}}$ are defined in the papers (see [1], [14], [16]). Several authors find all the derivations of an associative (Lie or non-associative) algebra (see [3], [1], [5], [7], [10], [16]). We find Der($\bar_{WN_{0,0,1_n}}$) of the algebra $\bar_{WN_{0,0,1_n}}$ and show that the algebras $\bar_{WN_{0,0,1_n}}$ and $\bar_{WN_{0,0,s_1}}$ are not isomorphic in this work. We show that the associator of $\bar_{WN_{0,0,1_n}}$ is zero.

The flamboyant progress of Korean Medicine in Mid-Chosun dynasty was possible with the existence of "Eui Rim Chwal Yo" and further more, it formed a main frame of "Dong Eui Bo Gam". Following results were lead to through comparing and analyzing "Yuk Dae Eui Hak Sung See", a chapter of "Eui Rim Chwal Yo". As well as "Yuk Dae Eui Hak Sung See" of "Eui Rim Chwal Yo" took the same chapter of "Eui Hak Ip Mun" as a main frame, it contains profiles of historic doctors and their clinical reports so that next generation doctors could follow, and furthermore had significant influences on Korean Medicine History, not to speak of "Yuk Dae Eui Bang" of "Dong Eui Bo Gam".

In Japan, on the volcanic line from Mt.Fuji to Hachijou Isl. in Pacific, we can see the many fissure erupted craters. The fissure eruption hasn't always left the rift caves. Recently I am investigated this era and recognized the rift caves. at Mt. Fuji 4. Miyake Isl. 3, Hachijou Isl. 3. The time of fissure eruption in Miyake Isl. make the long crack and gush the lava flow. But. we can see the rift caves only in the caldera. In the rift caves, we can see the thin coated lava on the scoria wall of the cavity and not only the side ways to extend by gasic pressure, on the surface of the earth. It is tow type rift caves. 1) The gas run to the side direction and built the cavities and after blowout the ground. 2) The gas built the cavity and then blowout the earth. I think that the thick scoria layers the most important factor and indispensable condition to built the rift caves.

In this paper graphical exploratory data analyses are proposed for ball games in sports. The plot of sequence of scoring points of each team can be used to see how the playing game has been processed until the end of each set or quarter. With the plot of sequential score differences through all the games we can see a dominance of each team and the times of score changes, i.e., turnovers. The ternary plots show the contours of scoring compositions for each player and enable us to compare the scoring patterns of each team if any. Using the score sequence plot we also can see the score pattern distribution of players. For demonstration we use the results of the gold medal match between Russia and Brazil for men's volleyball and between USA and Spain for men's basketball at the London 2012 Summer Olympics.

본 논문에서는 동영상 워터마킹에 대한 전반적인 기술과 응용 분야에 대하여 고찰한다. 동영상 워터마킹 기술은 압축영역, 비압축 영역, 실시간 응용 분야 둥으로 나누어 질 수 있다. 동영상의 모든 프레임에 워터마크로 정한 시그네쳐(signature)를 삽입하여 실험한 결과를 보여준다. 워터 마크를 주파수 확산 방식으로 원 영상의 모든 프레임에 삽입하여 워터마크의 세기 변화에 따른 화질을 PSNR로 계산하였고 워터마크 검출은 DCT 계수 합의 부호로 삽입된 시그네쳐를 복원한다. 검출된 시그네쳐의 시각적 상태에 따른 평균 PSNR값의 변화를 보여준다.
