The production of Secondary Non-ferrous Metals (SNM) is characterized by low investment, energy consumption and cost, less pollution as well as rather simple technology. In the past years, the SNM industry has seen relevantly rapid progress in China. Especially in the filed of clean hydrometallurgical treatment certain novel technologies for recovery and separation have successfully been elaborated, and a number of medium and small commercial plants established. On the basis of four common metals Cu, Al, Pb, Zn, and Ni, Co, this paper describes the status quo and progress of SNM industry in China, indicating that a lot of work should still be done in salvage of waste metals. It is recommended that measures for collecting and classifying SNM resource should be strengthened and the research on new technologies for scavenging such metals should be supported.

본 연구는 지역전략산업인 광산업을 중심으로 생산성 변화를 추정하고 이러한 변화를 기술변화 요인과 효율성변화 요인으로 분해함으로써 광산업의 생산효율성 향상 방안을 모색한다. 특히 기존의 연구들과 달리 투입최소화와 산출최대화를 동시에 고려하고 아울러 투입요소와 산출물의 잔여를 모두 반영할 수 있는 비방사적 비지향적 맘퀴스트 생산성지수를 분석에 활용한다. 실증분석 결과, 광산업의 생산성은 증가한 것으로 나타났으며, 이러한 생산성 증가는 주로 기술적 효율성 증가에 기인한 것으로 분석되었다. 또한 정부지원사업 수혜 여부와 지리적 입지에 따라 생산성 변화에 통계적으로 유의미한 차이가 있음을 확인하였다. 이와 같은 결과는 정부의 지역전략산업 육성정책이 광산업의 생산효율성 향상에 기여하고 있음을 시사하는 것으로 향후 광산업의 경쟁력 제고에 도움이 되는 실질적인 참고자료로 활용될 것으로 기대된다.

This paper studied balanced regional development focused on employment in Korea, by analyzing regional disparity between regional and industrial employment. A Gini-coefficient decomposition method and Panel Granger causality test were conducted, using raw data of the Census on Establishments reported by the Statistics Korea. The regional and industrial disparity of employment, based on the Gini-coefficient decomposition method, have increased by year. However, the growth rates of disparity are on the decrease. Most of employment disparity occurred from regional disparity between SMA (Seoul Metropolitan Area) and Non-SMA. Industrial disparity are occurred mainly by the service industry. The amount of contribution to the whole disparity of inter/intra regional employment was differed by each industrial sector. Also the causal relationship between employment growth of manufacture and that of service industry was analyzed by Panel Granger causality test. In national level, the employment growth in manufacture industry has conduced that in service industry. On the other hand, in the Non-SMA, only the employment growth in manufacture industry has augmented that in service industry. In conclusion, to reduce employment disparity, the strategy for balanced regional development should be emphasized. Different strategies are needed across regions and industries. Basically creating new job in the Non-SMA is inevitable. In view of stable employment, manufacture industry is more desirable rather than service industry.

Purpose - This study empirically examines the effects of environmental dynamics(dynamics of one's own company, dynamics of competitors, and dynamics of customers), within the franchise industry, on the dependence and conflict(dysfunctional conflict and functional conflicts) and the business performances(financial and non-financial). Furthermore, we empirically examined the effects of the dependence of franchise on the conflicts(dysfunctional conflict and functional conflict) and business performances(financial and non-financial). Finally, we empirically examined the effects of the conflicts of franchise (dysfunctional conflict and functional conflict) on the business performances(financial and non-financial). Research design, data, and methodology - Our study conducted a survey on the managers and owners of the franchises located in Seoul, Gyeonggi, and Incheon. The total number of valid samples was 230, and the structural equation model was analyzed by using AMOS program. Results - First, the environmental dynamics(dynamics of one's own company, dynamics of competitors, and dynamics of customers) in the franchise industry were shown to have statistically significant positive effect on the dependence of franchise. Second, among the environmental dynamics in the franchise industry, the dynamics of one's own company and the dynamics of the customers were shown to have a statistically significant positive effect on the dysfunctional conflicts of franchisees. However, in the franchise industry, the dynamics of competitors did not have a statistically significant effect on the dysfunctional conflict of the franchise. Third, in the franchise industry, the environmental dynamics(dynamics of one's own company, dynamics of competitors, and dynamics of customers) did not have a statistically significant effect on the functional conflicts of the franchises. Fourth, the dependence of franchise was shown to have a statistically significant positive effect on the conflicts(dysfunctional conflict and functional conflict). Fifth, the dysfunctional conflict of franchisees was shown to have a statistically significant negative effect on the business performances(financial and non-financial). Sixth, the functional conflicts of franchises was shown to have a statistically significant positive effect on business performances(financial and non-financial). Conclusions - From the franchise industry researches, the environmental dynamics were selected as the preceding factors and the relationship leading to dependence, conflict, and business performance were constructed into model.

Purpose - The purpose of this study is to suggest strategies and solutions for entering China in the tariff and non-tariff sectors of the cosmetic industry. Design/methodology/approach - This study analyzed the import tariff rate of cosmetics in China, and analyzed the export cost by actually interviewing the exporting companies to derive the economic effect of non-tariff measures. Findings - First, We proposed the use of the FTA business model (basic cosmetics), the use of Korea-China FTA tariffs (foam cleansing, toothpaste), and the use of APTA tariffs (perfume). Second, We proposed cooperation between the governments to facilitate customs clearance procedures and improvement of FTA awareness among corporate practitioners. Third, We proposed the expansion and support of the AEO MRA system and the expansion of Korea-China MOU conclusions regarding the certification system, and the international standardization of domestic licensing system and technical conditions. Fourth, We proposed the use of government-supported projects related to obtaining overseas certifications and overseas expansion through collaboration with the same industry. Research implications or Originality - HS3304 products excluded from the Korea-China FTA should take full advantage of the FTA business model. In addition, the non-tariff measure costs are fixed costs per year, so the ratio decreases as the number of exports and export volume increases.

Purpose - In this study, we explore the relationship between the degree of internationalization (DOI) and firm performance (DOI-P) of small and medium-sized enterprises (SMEs) in the manufacturing sector. Specifically, we investigate whether the costs and benefits dynamics concerning the internationalization of SMEs differ between high-tech and non-high-tech industries. Design/methodology - We extend the prior literature on this relationship by employing 5-year data on 589 Korean SMEs in the manufacturing sector and examining the moderating impact of the industry characteristics. Our findings reveal a U-shaped relationship between the DOI and SME performance. High-tech SMEs demonstrate an inverted U-shaped relationship, whereas non-hightech SMEs exhibit a U-shaped relationship. Findings - Our findings illustrate the importance of the industry factor in testing the performance impact of the internationalization of Korean SMEs. By incorporating industry dynamics, our results indicate that the DOI-P relationship depends on the context of the industry in which an SME operates. High-tech SMEs also display a higher DOI but are outperformed by non-high-tech SMEs for the entire internationalization path, which implies that high-tech SMEs face more challenges than non-high-tech SMEs while seeking internationalization. Originality/value - The findings strongly validate that significant benefits exist for SMEs undertaking internationalization. We also employ the contextual framework contributing to increasing the understanding of the intrinsic value of internationalization and resolving the mixed results issue on the DOI-P relationship, by illustrating that the industry factor leads to different dynamics of costs and benefits of SME internationalization; it also determines the shape and direction of the relationship.

The effects of Lavandula angustifolia extract fermented with Pediococcus pentosaceus DK1 on UVB-mediated MMP-1 expression and collagen decrease in human skin fibroblasts were determined, and the conversion of its components was also analyzed. Fermentation was performed at varying L. angustifolia extract and MRS medium concentrations, and optimal fermentation conditions were selected. L. angustifolia extracts showed decreased cytotoxicity after fermentation in the fibroblasts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extract showed MMP-1 expression 8.2-14.0% lower than that in UVB-irradiated fibroblasts treated with non-fermented extract. This was observed even at fermented extract concentrations lower than those of non-fermented extracts. Fibroblasts treated with fermented L. angustifolia extract showed 20% less reduction in collagen production upon UVB irradiation than those treated with non-fermented extracts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extracts showed 50% higher inhibition of ROS generation than those treated with non-fermented extract. Luteolin and apigenin glycosides of L. angustifolia were converted during fermentation, and identified using RP-HPLC and LC/ESI-MS. Therefore, the effects of L. angustifolia extract on MMP-1 expression and collagen decrease in UVB-irradiated human skin fibroblasts were increased through fermentation by P. pentosaceus.

To verify the dominance of microorganisms in wastewater biological treatment, PCR-DGGE (denaturing gradient gel electrophoresis) was performed as a supplementary support method for screening of the dominant microorganisms from activated sludge. Results suggest that the dominant microorganisms in activated sludge are primarily responsible for strengthening its effectiveness as a biological treatment system, followed by the non-main dominant microorganisms, whereas the non-dominant microorganisms showed no effects. The degree of microbial abundance present on the profile of PCR-DGGE was in line with the treatment efficiency of augmented activated sludge with isolated cultures, suggesting that PCR-DGGE can be used as an effective supplementary method for verifying culturable dominant microorganisms in activated sludge of coking wastewater.
