Since 2003, the biggest trade partner of South Korea has not been America but China. China appears to be a strong competitor of South Korea in every field of international market and even in IT industry, which has been one of the most competitive field of Korean Economy. IT Industry is now becoming a driving locomotive of economy in South Korea and China. It is reported that the IT gap between South Korea and China is shorten to be 1.7 years in 2006, from 2.6 years in 2003 and will be within one year in 2010. China has been aware of the urgent need of developing electronic and information industry in order to improve its productivity. In the results of the efforts to develop its IT industry, China has achieved average 25% yearly growth rate of IT manufacturing industry since 1991. Since 2004, South Korea has pursued IT 839 strategy. How South Korea and China can sustain the continuous development of IT industry. South Korea IT is expected to utilize China's through the mutual cooperation, which results in mutual benefit. To achieve the mutually benefited cooperation and specially to result in Small & Medium sized Korean companies' cooperation with China's, China is expected to improve the market system and create an environment of admitting intellectual property.

During investigating of shiitake mushroom competitors, 289 isolates of Trichoderma spp. were collected from shiitake mushroom farms in different districts and the Forest Mushroom Research Center of Korea, among which 29 representative strains were selected. Based on the DNA sequences of the rpb2 and tef1 genes and the ITS rDNA, and their morphological characteristics, they were identified as T. atroviride, T. citrinoviride, T. harzianum, T. longibrachiatum, and two undescribed species, Trichoderma spp. 1 and 2, which are considered to be the candidate of new species. Competition tests between Lentinula edodes (Sanjo302) and the Trichoderma species indicated that the six species of Trichoderma were significantly different from each other in terms of their ability to invade the mycelial blocks of shiitake. In both of dual cultures on potato dextrose agar and sawdust media, Trichoderma spp. 1 and 2 strongly invaded the mycelial blocks of shiitake. Our results suggest that the two Trichoderma species may cause potentially serious economic losses in shiitake cultivation of Korea.

These days, online media, such as blogospheres, online communities, and social networking sites, provides the uncountable user-generated content (UGC) to discover market intelligence and business insight with. The business has been interested in consumers, and constantly requires the approach to identify consumers' opinions and competitive advantage in the competing market. Analyzing consumers' opinion about oneself and rivals can help decision makers to gain in-depth and fine-grained understanding on the human and social behavioral dynamics underlying the competition. In order to accomplish the comparison study for rival products and companies, we attempted to do competitive analysis using text mining with online UGC for two popular and competing ramens, a market leader and a market follower, in the Korean instant noodle market. Furthermore, to overcome the lack of the Korean sentiment lexicon, we developed the domain specific sentiment dictionary of Korean texts. We gathered 19,386 pieces of blogs and forum messages, developed the Korean sentiment dictionary, and defined the taxonomy for categorization. In the context of our study, we employed sentiment analysis to present consumers' opinion and statistical analysis to demonstrate the differences between the competitors. Our results show that the sentiment portrayed by the text mining clearly differentiate the two rival noodles and convincingly confirm that one is a market leader and the other is a follower. In this regard, we expect this comparison can help business decision makers to understand rich in-depth competitive intelligence hidden in the social media.

Purpose - Market orientation is a key factor for business performance in today's fluctuating conditions. This study investigates whether the employment of innovation can improve the innovative capability and increase the performance by gaining competitive advantages or not. Therefore, this study aims to investigate the effects of market orientation on the performance of small and medium size distributer enterprises (SMDEs) in Iran. Research design, data, and methodology - Customer orientation, Competitor orientation, and Inter-functional coordination have been regarded as market orientation indices to determine the effects of these indices on marketing innovation, gaining competitive advantages, and companies' performance as well. Data were collected from managers and experts in SMDEs in Iran. The structural equations modeling are used for analysis. Results - The results indicated that marketing innovation has been improved in competitive companies that enjoyed a high level of Inter-functional coordination among the various units. Besides, marketing innovation resulted in gaining competitive advantages regarding cost management, concentration, and differentiation in these companies. In addition, it was observed that SMDEs that obtain competitive advantages are equipped to reap superior performance. Conclusions - With cost management, differentiation and concentration are more likely to enhance the enterprise efficiency and effectiveness than other companies. Additionally, competitiveness, inter-functional coordination, and marketing innovation in SMDEs have a positive impact on marketing innovation.

Examining the market orientation and learning orientaiton and these relationship with business performance has received considerable interest in the last decade. Despite these interest, our understanding of the structure of both market orientation and learning orientaion and the mechanism of those effect on business performance is apparently limited in figuring out the railroad industry in Korea. The purpose of this research was to conceptualize and measure the organizational culture dimension from the integrative framework of market orientation and learning orientation, and to analyze its relationship with business performance in the railroad industry. The findings from this research are such as follows; market orientation is a set of three interrelated components, i.e., customer orientation, competitor orientation, and inter-functional coordination. This finding is similar to that of Narver and Slater(1990; 1994) who conceptualized market-oriented culture as a combined set of those 3 components. Learning-oriented culture also has a significant positive effect on business performance. The research findings suggest that both market orientation and learning orientation do exist as different organizational culture dimensions to acquire the sustainable competitive advantage in the railroad industry.

Hydrogenated microcrystalline silicon (${\mu}c$-Si:H) thin film for solar cells is prepared by plasma-enhanced chemical vapor deposition and physical properties of the ${\mu}c$-Si:H p-layer has been investigated. With respect to stable efficiency, this film is expected to surpass the performance of conventional amorphous silicon based solar cells and very soon be a close competitor to other thin film photovoltaic materials. Silicon in various structural forms has a direct effect on the efficiency of solar cell devices with different electron mobility and photon conversion. A Raman microscope is adopted to study the degree of crystallinity of Si film by analyzing the integrated intensity peaks at 480, 510 and $520\;cm^{-1}$, which corresponds to the amorphous phase (a-Si:H), microcrystalline (${\mu}c$-Si:H) and large crystals (c-Si), respectively. The crystal volume fraction is calculated from the ratio of the crystalline and the amorphous phase. The results are compared with high-resolution transmission electron microscopy (HR-TEM) for the determination of crystallinity factor. Optical properties such as refractive index, extinction coefficient, and band gap are studied with reflectance spectra.

Adsorption on goethite of individual component from a solution containing phosphate, sulfate, or copper ion was investigated. Competitive adsorption in the binary and ternary solution systems composed of phosphate, sulfate, and copper ions was also investigated. In competitive adsorption systems with phosphate and sulfate ions, the presence of phosphate ion reduced the adsorption of sulfate ion largely. On the other hand, the presence of sulfate ion caused only a small decrease in phosphate adsorption. This result suggests that phosphate ion is a stronger competitor for adsorption on goethite than sulfate ion, which is consistent with the higher affinity of phosphate for the surface compared to sulfate ion. Compared to the results from single-sorbate systems, adsorption of copper ion in the binary system of sulfate ion and copper ion was found to be enhanced in the presence of sulfate ion. Addition of sulfate ion to the binary system of copper ion and phosphate ion resulted in a small enhancement in copper sorption. This result implies that the presence of sulfate ion promotes adsorption of the ternary complex FeOHCuSO$_4$. The adsorption isotherms could be well described by the Langmuir adsorption equation.

A simple, highly sensitive and selective method based on the rhodamine B-covered gold nanoparticle with dual-readout (colorimetric and fluorometric) detection for $\small{L}$-cysteine is proposed. A mechanism is that citrate-stabilized AuNPs were modified with RB by electrostatic interaction, which enables the nanometal surface energy transfer (NSET) from the RB to the AuNPs, quenching the fluorescence. In the presence of $\small{L}$-cysteine, it was used as a competitor in the NSET by the strongly Au-S bonding to release RB from the Au surface and recover the fluorescence, and the red-to-purple color change quickly, which was monitored simply by the naked eye. Under the optimum conditions, the detection limit is as low as 10 nM. The method possessed the advantages of simplicity, rapidity and sensitivity at the same time. The method was also successfully applied to the determination of $\small{L}$-cysteine in human urine samples, and the results were satisfying.
