Globalization has brought about rapid economic, technological, and cultural changes. In order for countries around the world to communicate, recognize and understand globalization, creativity or planning ability can be used to code. In this paper, we would like to present and prove a data analysis that can solve world problems. In the global market, the value of goods or services increases with connectivity. This connection is becoming one of the factors that increase the value of culture. Changes taking this into account promoted cultural spread and innovative growth, and increased productivity and competitiveness in each region of the world. This paper compares the income of the middle class in the United States on the impact of globalization and anti-globalization on cultural spread and innovative growth. Globalization has created an environment in which various elements of K-culture can interact and spread. Through the Internet, social media, and international travel, globalization has had a positive impact on Korea's innovative growth. In areas such as economic activity, technological innovation, and creative industries, globalization has facilitated new tech and approaches, Through this, it changed the existing economic model and contributed to exports K-culture with a new middle class model. However, globalization in the cultural industry can result in the loss of regional characteristics & individuality, which can lead to the middle class cultural unification and alienation(chasm). As a result of the empirical analysis of K-exports for the middle income in the United States, cultural diffusion and innovation must be developed even in anti-globalization. With these industrial changes the soft power value of the Korean Wave proves that it can create value for use for the middle class of major exporting countries.

This study aims to examine the interaction between jazz musicians playing in domestic jazz clubs and audiences visiting jazz clubs in depth. This study conducted an in-depth interview, a qualitative research methodology, to find out the subjective views of jazz club musicians and audiences about jazz club performances, and analyzed the contents and presented the results. The results of this study are as follows: First, jazz musicians perceived jazz clubs as the center point of their musician careers, and from the perspective of the audience, jazz clubs were a place where jazz lovers gathered voluntarily, and where they could enjoy musical communication in a comfortable atmosphere. Second, jazz club performances gave jazz musicians the autonomy to play and considered them suitable for creating optimized sounds, and the audience recognized that jazz musicians could experience performances vividly on stage close to the audience. Third, the way jazz musicians interacted with the audience was active for musical communication with the audience, and the audience preferred the way that interaction could contribute to their performance, and the audience recognized the interaction through musical communication with the musician and the musician's consideration for the audience. Fourth, jazz musicians played a major role in realizing a performance in which interaction with the audience was complete, and audiences perceived interaction as a joy of improvisation, a bond with jazz musicians, and a special experience. This study confirmed the jazz club's status as a cultural space for the public's jazz enjoyment as well as a performance base that ultimately promotes the development and spread of jazz gods in Korea, and it is meaningful that it can serve as a guideline for jazz performance planning and jazz club operation from an art management perspective.

The fusion stream of recent broadcasting and communication make multimedia content served in the area of broadcasting into IPTV service which transmits it through high-speed internet, cable TV net and satellite net in realtime. However, as the digital broadcasting service is extended to various media, the security of IPTV service content provided to users by service provider is not fully supported by CAS(Conditional Access System) provided by existing broadcasting system. This paper proposes interactive certification protocol which can efficiently distinguish the receiving-qualification of user between Set-Top Box and Smart Card which are parts of configurations for IPTV system. The proposed protocol uses hash function to make Set-Top Box transmit receiving-qualification about the channel fee which user pays more properly than existing protocol. Also, the proposed protocol uses session key generated between receiver and smart card through inter certification process and encrypts EMM not the service to be used by anyone illegally.

The number of users of SNS has been steadily increased along with the popularity of smart phones, since marketing using SNS is easy to communicate and fast to spread, many companies are actively utilizing SNS marketing. In this study, we established a hypothesis by selecting SNS marketing attributes based on prior research as informational, interactive, entertainment and reliability. In this study, we are going to examine the impact on SNS marketing on purchase behavior at the convenient store to provide basic data for sale promotional strategy. Analysis of differences in SNS marketing attributes according to the characteristics of the survey participants showed that differences in information were significant in age and monthly income, and interaction was significantly different from gender. Among SNS marketing attributes, information, entertainment and reliability showed significant positive effects on satisfaction, and the interactivity was rejected because it did not have a significant impact. While interactivity, entertainment, and reliability of SNS marketing attributes significantly affected satisfaction, it was found that information has not significantly affected them. Satisfaction also had a significant impact on purchase intentions.

In order to guarantee the multiuser transmission performance of a chirp spread spectrum system, the cross-correlation coefficient (CCC) among multiple users should be carefully considered. In this paper, we propose a chirp rate allocation scheme for reducing the multiple access interference based on the cross-correlation coefficient. The simulation results show that the proposed scheme can improve the multiple access interference performance.

Reactive diffusion couples between Fe-5.8at.%Si and (Si wafer, $FeSi_2$, or FeSi alloy) were heat-treated at 1423k. The only layer of $Fe_3Si$ phase was formed in each diffusion couple. The width of $Fe_3Si$ layer was proportional to square root of diffusion time in each kind of diffusion couple. Growth rate of $Fe_3Si$ layer was relied on the concentration of Si in the supplied source of Si atoms. Interdiffusion coefficient of $Fe_3Si$ has been determined from the derived relation between growth rate constant and interdiffusion coefficient in this work. It was shown that the behavior of Kirkendall's void in $Fe_3Si$ layer was not affected by the kind of Si source. But solid solution $\alpha$ was formed in the diffusion couple between Fe-5.8 at.%Si and $Fe_3Si$ alloy. Kirkendall's voids in diffusional $\alpha$ were neglectively smaller than the case of $Fe_3Si$ phase growth.

Electrochromism이란 기전력 방향에 의한 가역적으로 색이 변하는 현상을 말하며, 열린 회로 기억성을 가지며 소비전력이 적고, 우수한 착색 효율을 갖는 등 여러 가지 유용성 때문에 디스플레이 및 전기적 착색 유리창에의 기술적 적용 가능성을 보이고 있다. 본 연구에서는 가장 우수한 일렉트로크로믹 특성을 내는 것으로 알려진 WO3 박막과 대향 전극으로 V2O5 박막을 사용하였다. 이들 박막은 알칼리 이온 주입물질이며, coloration.bleaching상태에서 광학 밀도가 크고, 내구성이 좋으며, 작은 비용으로 재료를 사용할 수 있다. 그리고 더 우수한 장점으로 부각되는 대면적의 코팅의 매력적인 기술인 졸겔법으로 제조 가능한 특성을 가지고 있다. 졸겔법 및 진공증착법으로 박막을 제조하고, 박막산화 및 수명저하 등의 위험이 적은 리튬이온을 이용하여 소자를 제작한 후 일렉트로크로믹 특성을 조사하고, 우수한 소자의 제조조건을 얻고자 하였다. 측정결과 졸겔법으로 제조된 WO3 박막과 V2O5 박막을 수증기 분위기에서 50$0^{\circ}C$로 1시간 열처리한 경우 가장 우수한 투과 변화율을 나타내었다. 정상전압인 2 volt보다 높은 3 volt로 cyclic voltamogram을 측정하는 과정에서 정.역방향 동작을 거듭할수록 peak이 크게 감소하는 현상을 발견하였으며, 양이온의 흐름에 의해 물질의 이동이 발생할 것이라는 판단아래 Auger depth profile을 측정한 결과 WO3막의 텅스텐과 ITO막의 인듐이 상호 확산하는 것을 관찰할 수 있었다. 이를 방지하기 위해 수백 의 텅스텐 박막을 WO3 막 위에 증착한 후 cyclic voltamogram과 Auger depth profile을 측정한 결과, cyclic voltamogram의 peak의 감소량이 1/10이하로 감호하였으며, 리튬이온의 흐름에 의한 인듐과 텅스텐의 이동을 효과적으로 방지할 수 있었다. 따라서 텅스텐 확산방지막의 삽입이 소자의 수명을 향상시킬 수 있는 효과적인 방법이라고 사료된다.

In this study, a numerical simulation technique for coastal area where wave and current interactions are observed is proposed. Considering the spatial scale of coastal area and the coastal processes such as wave, current, shoaling, wave breaking, and inundation processes, boussinesq equation model is used. A depth-integrated transport model based on the consistent assumption with the boussinesq equation model is used for the prediction of solute transport. To solve the equations, finite volume method with an approximate riemann solver is used. The proposed model is applied to a coastal area and reasonable computational results are obtained.
