인쇄산업과 미디어에 대한 패러다임이 변화하고 국내외 경기 불황으로 내수와 수출 모두 꽁꽁 얼어붙은 한 해였다. 전통적인 오프셋 인쇄 물랑이 급격하게 주는 가운데, 수년 간 시장을 확대해왔던 디지털 인쇄 분야도 성장세는 이어갔지만 추세는 다소 주춤하는 모양새다. 다만 인쇄주문 요구의 다양화에 따라 특수인쇄 수요가 꾸준히 증가하고 있으며, 특수 표현을 요구하는 패키지와 후가공 분야에서는 성장의 가능성이 감지됐다.

This study was conducted from the time when discussion of improvement and keeping heavy taxation on multiple home owners was began, experts who may express professional opinion such as realtors, tax accountants and revenue officers were picked up besides the direct interested parties such as single and multiple home owners. This study collected their various opinions regarding whether keeping the heavy taxation system on multiple home owners or not and the effect of it. As a result of the survey, people living in Seoul who owned more houses showed higher awareness about heavy taxation on multiple home owners, and people agreed more about abolishing the heavy taxation when they own more homes. From this study, it was found out that different recognition about heavier transfer income tax on multiple home owners of each person concerned and necessity of rearranging this uncertain condition of temporary regulation in the future. The tax law should be improved to supply clear policy signals to the market for recovery of housing transactions and supply expansion of jeonsei to monthly rental housing and managing of taxation policy which reflects taxpayers' opinion may correspond to more effective and fair taxation principle.

We, for the first time, developed a Raman lidar system which can remotely detect surface CO₂ volume mixing ratio (VMR). The Raman lidar system consists of the Nd: YAG laser of wavelength 355 nm with 80 mJ, an optical receiver, and detectors. Indoor CO₂ cell measurements show that the accuracy of the Raman lidar system is calculated to be 99.89%. We carried out the field measurement using our Raman lidar at Pukyong National University over a seven-day period in October 2019. The results show good agreement between CO₂ VMRs measured by the Raman lidar (CO₂ Raman Lidar) and those measured by in situ instruments (CO₂ In situ) which located 300 m and 350 m away from the Raman lidar system. The correlation coefficient (R), mean absolute error (MAE), and root mean square error (RMSE) between CO₂ In situ and CO₂ Raman Lidar are 0.67, 2.78 ppm, and 3.26 ppm, respectively.

A new Bacillus strain designated as MP56 producing antimicrobial substance has been isolated from the mud flat of Korea. The strain MP56 was found to exhibit broad spectrum of antimicrobial activity against Gram-positive pathogenic microorganisms and MDR (multi drug resistant) strains. The 16S rRNA sequence revealed that the MP56 was closely related to Bacillus subtilis with 99.93% homology. The optimal medium composition for production of antimicrobial substance in the B. subtilis MP56 were 1% mannitol, 1% oat meal, 0.01% $CaCl_2$. Antimicrobial activity of the culture broth against different pathogenic strains was assessed using the antimicrobial spectrum. The result suggests that Bacillus strain MP56 produces high quality antimicrobial substance that might be very useful to control varieties of pathogenic microbial growth.

In these days, multiple-path generation method is highly demanded in practice and research areas, which can represents realistically travelers behavior in choosing possible alternative paths. The multiple-path generation algorithm is one of the key components for policy analysis related to ATIS, DRGS and ATMS in ITS. This study suggested a method to generate multiple Possible paths from an origin to a destination. The approach of the suggested method is different from an other existing methods(K-shortest path algorithm) such as link elimination approach, link penalty approach and simulation approach. The result of the multi-label vine-building shortest path algorithm(MVA) by Kim (1998) and Kim(2001) was used to generate multiple reasonable possible paths with the concept of the rational upper boundary. Because the MVA algorithm records the cost, back-node and back-back node of the minimum path from the origin to the concerned node(intersection) for each direction to the node, many potential possible paths can be generated by tracing back. Among such large number of the potential possible paths, the algorithm distinguishes reasonable alternative paths from the unrealistic potential possible paths by using the concept of the rational upper boundary. The study also shows the very simple network examples to help the concept of the suggested path generation algorithm.

As recent inflows of foreign immigrants to relatively advanced countries in Northeast Asia have rapidly increased, Japan in particular uses 'multicultural coexistance' as a key concept for developing both discourse and policies on them. This paper is first of all to suggest a new typology of multicultural societies in the world ill order to differentiate the case of Northeast Asian countries from those of Western countries. And this paper is to suggest that foreign immigrants in Japan have different positions in labor markets and living experiences according to historical and social backgrounds as well as their nationality. The transformation process towards multicultural society is not only historical and social but also geographical and spatial, as foreign immigrants have made different spatial distribution and regional segregation in types. In order to control this socio-spatial process towards multicultural society, Japan has developed the concept of 'multicultural coexistence' similar with that of multiculturalism in Western countries. This concept seems to be quite significant as it has been initiated by local communities for symbiotic relationship between foreign immigrants and native Japanese dwellers. But it can be regarded as a strategic ideology to control foreign immigrants as it targets mainly on Nikkeijin, and is usually concerned with the cultural aspect. Seen from a theoretical point of view, this concept can be seen as closed with liberal multiculturalism as opportunity equity, but far from corporative multiculturalism as outcome equity, and it is on the process transferring from the first stage of tolerance to the second stage of legislation of nondiscrimination, while being distant from the third stage of legislation paradigmization of recognition, and hence appears to be easily reverted to assimilationism.

In this paper, we propose a novel approach which models multilingual story link detection by adapting the features such as timelines and multilingual spaces as weighting components to give distinctive weights to terms related to events. On timelines term significance is calculated by comparing term distribution of the documents on that day with that on the total document collection reported, and used to represent the document vectors on that day. Since two languages can provide more information than one language, term significance is measured on each language space and used to refer the other language space as a bridge on multilingual spaces. Evaluating the method on Korean and Japanese news articles, our method achieved $14.3{\%}\;and\;16.7{\%}$ improvement for mono- and multi-lingual story pairs, and for multilingual story pairs, respectively. By measuring the space density, the proposed weighting components are verified with a high density of the intra-event stories and a low density of the inter-events stories. This result indicates that the proposed method is helpful for multilingual story link detection.

The purpose of this paper is to examine how multi-cultural acceptability affects the perception of necessity of unification through structural equation model. The multi-cultural acceptability, familiarity with North Korean defectors, and awareness of unification were selected as the latent variables and the full / partial mediator models were built for structural equations. The observed variables for each latent variable were data that were collected through the National Survey on the Integration of North and South Korea conducted by the Korea Institute for National Unification in 2015. As a result, the acceptance of multiculturalism had a significant effect on the intimacy of the defectors, which had a positive effect on the recognition of the need for unification. The intimacy of the defectors was more influential as a parameter for full mediation than for partial mediation. Although the consciousness of unification gets weakened by postwar generations, that the phenomenon that changes into a multicultural society plays a part in recognizing the necessity of unification. In addition, the increase of North Korean defectors may ultimately become a factor in recognizing the need for unification. This study demonstrated that increasing the acceptance of multiculturalism can increase the need for unification, which means that more research fields can be derived.

This paper aims to examine systematically how audiences' exposure to crime news influences their multicultural acceptability. In particular, the analysis has focused on how the variance in the effects of contacts with crime news on foreigners takes place, according to the types of media and communication favored among the audiences. Also, with perceived risk toward crime as a mediating variable, this research scrutinizes the way crime news on foreigners comes to influence multicultural acceptability among the audiences. While various news sources and communication channels are influential in strengthening the perceived possibility of crime on the individual level, the results show, television seems to be particularly more effective with regards to the perceived prevalence of crime on the social level (RQ 1). Also, while contacts with crime news through 'dialogic' media rarely influence multicultural acceptability significantly, 'discursive' media and face-to-face contacts have negative impacts on the multicultural acceptability (RQ 2). Consequently, perceived risk on the social level seems to play the role of full mediation in the process where audiences' contact with crime news through discursive media influences their multicultural acceptability (RQ 3). Based on these findings, both theoretical and practical implications were discussed.
