Electrical construction cost index is composed of the cost of albor and material. The producer price index is used to the cost of material. The Bank of Korea restructured the formation method and the basic period of the producer price index in 2013. Because fixed-weighted method can't faithfully reflect industrial structure changes. The weighted value and price index of fixed-weighted method is fixed on the basicp eriod. Electrical construction cost index is changed from fixed-weighted method to chain-weighted method in september 2014, because of these on the need. But the change of organization in formation method changes the weighted value. So there is the need of analysis about the statistical continuity of electrical construction cost index. This study is focused on the time series analysis between fixed-weighted and chain-weighted electrical construction cost index. We uses unit root test, cointegration test, regression analysis of long and short term equation, fitness for the estimation of static forecast as time series analysis. We verify that chain-weighted electrical construction cost index can be replaced to fixed-weighted construction cost index accounting analyses result. So users of it recognize that chain-weighted electrical construction cost index has statistical continuity.

Electrical construction cost index has been applied fixed-weighted method. But fixed-weighted method can't faithfully reflect industrial structure changes. Because the weighted value and price index of fixed-weighted method is fixed on the basic period. Electrical construction cost index is composed of the cost of labor and material. So it fluctuates sharply whenever the construction association of korea announces the laborer's wage of electrical construction. And it depends on only the producer price index changes that is related to electrical construction since then. So a study is focused on developing electrical construction cost index applied chain-weighted method. Because chain-weighted method can reflect the realities of the electrical construction and alleviate the sudden changes of labor cost with link index. We verify that chain-weighted method relieves the step states of electrical construction cost index applied fixed-weighted method.

Multi-Level Marketing distribution process to reduce occurs in a number of the distribution costs to consumers of reducing its profits outside the area subject to the non-store or stores is the way to a special sale. Japan for the multi-level marketing Article 33 of the Act on Specified Commercial Transactions at or below the regulatory chain is defined as dealers. However, unlike other legislative attention two -dimensional chain for sales transactions are regulated. A chain of Japanese regulations on sales transactions, the definition is very specific and detailed regulations, and the chain is specifically for sales transactions in detail how to take regulatory and regulatory relief of pre- and post- regulatory focus, and the streamlining of regulatory aimed at restrictions on how the implications of such a large country.

Chain-linking is a method for aggregating volume measures which would improve the quality of estimates of economic growth over the present fixed base in Korea. There is a risk that choice of chain-linking techniques such annual overlap, one-quarter overlap or over-the-year overlap may create an artificial seasonality to the volume series. The empirical results on Korean GDP suggest that the use of the annual overlap is recommended. And conducting seasonal adjustment after chain-linking to produce the chain-linked seasonally adjusted GDP is more appropriated in Korea.

In this paper, the performances of wireless asynchronous transfer mode (ATM) cell transmission in mobile work are analyzed. We adopt 16Star QAM as amodulation technique in wireless channel and considered Reed-Solomon, convolutional, and concatenated coding to improve the error rate performances, and also proposed the Partial Concatenated Coding (PCC) technique as UEP(unequal error protection) code for efficient transmission of ATM cell in the air interface. We consider Doppler's effect, Rician fading, and diversity technique of maximal-ratio combining (MRC) for mobile channel model. For performance measure, we analyze bit error rate, ATM cell loss probability, ATM cell error probability, and network performances of ATM cell transmission delay and throughput. The numerical results show that the adoption of PCC is a prospective way for the evolution of future wireless ATM network on mobile environment.

I. Identity of Yeonsegeuk as total arts. The purpose of the thesis is to arrange the identy of Yeonsegeuk(Kino-Drama) which is theatre or film. The process of study is tried to discuss on the aethetic of Yeonsegeuk. II. Appearance of Yeonsegeuk and negative disputation of yeonsegeuk The first imported Yeonsegeuk from Japanese in Korea is made by the group of Mizuno Ganggetsu(水野觀月) on Oct. 16. 1915 at Pusan and also to run in Seoul at Hwanggeumgwan. The first of Korean Yeonsegeuk is by Kim, Dosan, a leader of Singeukjwa(theare group) on Oct. 27. 1919 at Danseongsa. Before the liberation of Korea from Japan all made korean Yeonsegeuk are 28 works. III. Dramatic form of Yeonsegeuk I study on the relation between Yeonsegeuik and Sinpageuik(new theatre of modern drama in 1920's). I find that Yeonsegeuik admitted the thechnics of the Sinpageuik and the contents. If We think that the theatre is synthetic art which genealize all arts, we can insist that the Yeonsegeuk is valued the total art as new performance to comply with film art to theatre. Conclusionly Yeonsegeuk is called 'Expanded Theatre' as the new performance which must be dicussed in the view of total art. VI. Discussion on the the aethetic of Yeonsegeuk When we compare the structure of film with the structure of theatre, we can't find a diffrent element between the structure of two art in art semiotic. But we find a fact that film art has special elements in mechanics character which are camera working and motage. These technics influence on the audience's mind. It is different point between Japan and Korean's Kino-drama and Germany's that is to admit the aethetic of total art or not. V. Yeonsegeuk as new performance During Korean modern times Kino-drama was first a kind of total art with stage and screen. But it is regretable that Kino-drama didn't have the background of theory which discourse on the comprehension of total art. As the result Kino-drama bring the confusion of argument that Kino-drama is total art or expanded theatre. This confusion will be disputed on film art as performing arts or future art as expanded film and total art.

Hybrid disaster refers to a type of unexpectedly large-scale disaster that results from continuous or simultaneous occurrence of natural and social disasters. Since hybrid disaster is a completely new type of disaster that has simultaneity and continuity, it requires a different management method compared to the conventional disaster management method. Accordingly, this study suggested policy directions for hybrid disaster response system of Korea after reviewing hybrid disaster response systems in developed foreign nations.

This paper describes error resilient coding scheme is added in WLL system and its application for robust low-bit rate still image transmission over power controlled W-CDA system Rayleigh fading channels. The baseline JPEG compressing methods are uses in image coding over wireless channel. The channel uses Reed-Solomon(RS) outer codes concatenated with convolutional inner codes, and truncated type I hybrid ARQ protocol based on the selective repeat strategy and the RS error detection capability. Simulation results are proved for the statistics of the frame-error bursts of the proposed system in comparison with conventional WLL system. it gains the 2 dB of the Eb/No in same BER.
