문화산업은 국가경제성장에 있어서 역할이 점차적으로 증대하고 있으며, 타 산업에 미치는 윈도우효과가 크기 때문에 더욱 주목 받고 있는 산업이다. 특히 중국은 2000년대 이후 산업구조고도화 측면에서 문화산업의 발전을 적극적으로 추진하고 있다. 한국은 중국보다는 상대적으로 일찍이 문화산업에 대한 집중적인 투자를 통해 국가경제성장에서 주도적인 역할을 담당하고 있다. 따라서 본 연구는 중국과 한국 양 국가 간의 문화산업의 효율성을 비교함으로써 문화산업이 경제성장에 미치는 영향과 잠재력에 대해 비교해 보고자 한다. 한국과 중국의 문화산업의 효율성을 비교할 때 가장 큰 애로점은 비교 가능한 통계자료의 구축이다. 본 연구에서는 효율성 분석을 위한 투입변수로 사업체 수와 종사자 수를 선정하고 산출변수는 문화산업의 매출액을 선정한다. 그리고 DEA-Malmquist지수를 통해 효율성을 비교 분석한다. 한국의 자료는 지자체 통합DB와 KOSIS에서 기초 자료를 이용하고 있으며, 중국의 자료는 국가통계국의 자료를 이용하고 있다. 분석기간은 2013-2017년으로 설정하고 있다. 분석결과에 의하면 한국의 Malmquist지수는 1.048로 나타나고 있으며, 중국은 1.041로 나타나고 있다. 즉 한국은 분석 기간 중 4.8%의 효율성이 개선되고 있으며, 중국은 4.1%의 효율성이 개선되고 있는 것으로 나타났다. 이러한 분석 결과는 이 기간의 한국은 문화산업이 성숙기로 접어들고 있는 시기이며 중국은 성장기로 진입하는 시기이기 때문으로 해석할 수 있다.

Topological photonic nanocavities are considered to possess outstanding optical performance, and provide new platforms for realizing strong interaction between light and matter, due to their robustness to impurities and defects. Here hybrid plasmonic topological photonic nanocavities are proposed, by embedding various plasmon nanoantennas such as gold nanospheres, cylinders, and rectangles in a topological photonic crystal corner-state nanocavity. The maximum quality factor Q and minimum effective mode volume V_eff of these hybrid nanocavities can reach the order of 10⁴ and 10^-4 (𝜆/n)³ respectively, and the high figures of merit Q/V_eff for all of these hybrid nanocavites are stable and on the order of 10⁵ (𝜆/n)^-3. The relative positions of the plasmon nanoantennas will influence the coupling strength between the plasmon structures and the topological nanocavity. The hybrid nanocavity with gold nanospheres possesses much higher Q, but relatively large V_eff. The presence of a gold rectangular structure can confine more electromagnetic energy within a smaller space, since its V_eff is smallest, although Q is lowest among these structures. This work provides an outstanding platform for cavity quantum electrodynamics and has a wide range of applications in topological quantum light sources, such as single-photon sources and nanolasers.

This paper, presents a comparison between numerical analysis and field test on a real offshore platform in Bohai Bay, China. This platform is a steel jacket offshore platform with vertical piles. The field testing under wave-induced force and wind force etc. was conducted, in order to obtain the dynamic parameters of the structure, including the frequencies of the jacket platform, as well as the corresponding damping ratios and mode shapes. The natural excitation technology (NexT) combined with eigensystem realization algorithm (ERA) and the peak picking (PP) method in frequency domain are carried out for modal parameter indentification under operational conditions. The three-dimeansional finite element model (FEM) is constructed by ANSYS and analytical modal analysis is performed to generate modal parameters. The analytical results were compared with experimental results. A good agreement was achieved between the finite element and analysis and field test results. It is further demonstrated that the numerical and experimental modal analysis provide a comprehensive study on the dynamic properties of the jacket platform. According to the analysis results, the modal parameters identification under ambient excitation can calibrate finite element model of the jacket platform structures, or can be used for the structural health monitoring system.

The iron and steel sector is caught between two worlds: "carbon reduction" and "development." The goal of this study is to show that optimizing asset structure to boost intangible assets, particularly brand assets, is a viable strategy to achieve low-carbon development. This study uses panel data from 38 A-share companies in China's iron and steel industry from 2010 to 2020, as well as World Brand Lab data, to create a comprehensive impact index of enterprise value from the standpoint of an asset structure optimization, and to test the impact of intangible assets and brand equity on enterprise value. The findings show that: the asset structure of iron and steel enterprises is closely related to enterprise value, implying that iron and steel industry development necessitates a transformation of quantity control and quality improvement; the proportion of intangible assets in the asset structure of iron and steel enterprises plays a positive and critical role in enterprise value under surplus conditions. The iron and steel industry begins to shift from tangible to intangible assets; there is heterogeneity in the iron and steel industry transformation. Given certain technological levels, the share of brand assets contributes significantly to the increase in enterprise value.

Purpose - The industrial structure upgrading can play an important role in promoting the carbon emission efficiency. Thus, this paper attempts to study the impact of industrial structure upgrading on carbon emission efficiency in order to reduce carbon emissions. Research design, data, and methodology - This paper selects panel data of 30 provinces and municipalities (autonomous regions) in China from 2001 to 2016, and divides them into three regions. The Moore index is used to measure the industrial structure upgrading, the non-radial SBM model based on undesired output is used to measure the slack variable to calculate the total factor carbon emission efficiency. Finally the impact of industrial structure upgrading on the carbon emission efficiency are analyzed. Results - It is found that the Moore index and the carbon emission efficiency in the eastern region is the highest in the three regions. Conclusions - The influence of various influencing factors on carbon emission efficiency is different between regions. The Moore index has a positive effect on the carbon emission efficiency in the eastern region, and has a negative influence coefficient on the central region. The effect on the western region is not obvious.

The present study purposed to identify differences and similarities in traditional residential space among Korea. China and Japan, which share similar social structure, and to make a comparative analysis on differences in traditional residential space according to family relation in the three countries. For these Purpose, this study selected residences, which are similar to one another in terns of time, class and economy and analyzed them using their floor plans and photographs. The results of this research are as follows. Knrea, China and Japan, all of which have family-centered social structure, separate their residential space from the external society and particularly women's space is placed inside men's space or in a secluded area. The most remarkable characteristic of residential space in Korea is the division of living spare between men and women. Space is allocated according to the hierarchical order of families. In this way, the position or order of family members is reflected in the use of space. Characteristically in China based on the large-family system each family is given a space for independent life. Particularly as the relation among brothers is emphasized, space is allocated equally to all brothers but the status of a space is determined by the order of the residents. Residential space in Japan is organized to emphasize the absolute authority and status of the head of the family. As the space is planned focused on the family head's daily life and guest reception, the relation among other family members is ignored. That is, Japanese residence is a social space for the family head's guest reception, Chinese residence is a family-centered space rather than a social space, and Korean residence accommodates both space for family life and social space.

미국과 중국의 전략적 경쟁이 격화되면서 중국을 비롯하여 전세계적으로 경제 제재가 더욱 빈번하게 사용되고 있다. 미국의 동맹국이면서도 중국을 최대 교역국으로 두고 있는 한국은 중국의 사드(THAAD) 배치에 대한 보복에서 보듯이 향후에도 경제 제재에 맞닥뜨릴 가능성이 높다. 이러한 배경에서 본 논문은 비공식성을 중심으로 중국의 경제 제재를 분석한다. 중국은 경제 제재를 거의 인정하지 않는다. 대부분의 경우, 중국은 한국의 사드 배치 사례처럼 거대한 시장을 가진 구매자로서의 지위를 적극 활용하여 비공식적으로 경제 제재를 시행한다. 핵심이익과 관련되어 있거나 유리한 무역구조를 활용할 수 없어 실질적인 제재 효과를 발휘할 수 없는 경우, 그리고 상호 분쟁이 고조되어 비공식성을 유지할 수 없을 때에만, 공식적인 대응을 한다. 중국의 비공식적 경제 제재에 취약한 한국은 무역구조를 개선하는 것과 함께 비공식성을 비롯한 중국의 경제 제재가 갖는 특성을 심도 있게 분석하면서 다양한 전략과 방안을 통해 이에 대비해야 할 것이다.

본 연구는 2006년 8월부터 2007년 9월까지 여수, 남해, 진도, 무안, 거문도, 서산 및 중국의 산동에서 포획한 낙지 유전자 집단을 분석하기 위하여 미토콘드리아 16S rRNA 염기서열로 조사했다. 유전자 분석은 총 28 개체로부터 11개의 haplotype이 발견되었다. 유전자 분화율은 0.2-1.2% 범위로 나타났다. Haplotype에 대한 PHYLIP 및 network 조사에 따르면 낙지는 두개의 clade (clade AIclade B)로 나뉘어지며, clade 사이의 분화율은 0.4%로 나타났다. 지역적 거리에 따라 haplotype이 다음과 같이 분화되었다. 하나는 여수, 남해, 무안, 진도 haplotype과 다른 하나는 서산, 거문도, 산동 haplotype으로 나뉘어졌다. 계충구조 분석에서도 한국 낙지집단 및 중국과의 유전적 차이를 볼 수 있으나, 현저한 지역적 차이는 나타나지 않았다. 따라서 한국연안에 서식하고 있는 일부 낙지집단은 gene flow에 의해서 유전적 동질성을 나타낼 수 있지만, 한국집단 간 뿐만 아니라 중국집단과의 유전적 분화는 지역적 거리 및 장벽으로 인하여 제한적인 gene flow로 설명될 수 있다.

As the e-business developed fast and more firms embrace CRM as a core e-business strategy, it is getting more important to assess the firms. The CRM is approaching customer-centric. This approach focuses on the long-term relationship with the customers by providing the benefits of the customer rather than based on what the company wants to sell. How to establish the overall efficiency and effectiveness of a global enterprise becomes more and more important to the E-business. The study investigates the cross-national psychometric prosperities of the establishment in the E-business. Using a cross-national survey of customers from Korea and China to compare the Korean customers' acceptance of e-business with the Chinese customers', and compare the development of e-business in Korea with the development in China it will be found that Korea and China samples shared a somewhat similar factor structure. And there are also some differences between Korea and China. These findings suggest that the way to establish the e-business strategy is influenced by the cultural effects. So focusing on the cultural differences among the countries becomes more and more important, this study will help to analysis how to use the different cultural dimension to establish the better CRM system in the e-business field.
