Technology commercialization capability plays such a critical role in successfully converting the performances from firms R & D activities into their actual revenues that a lot of studies have paid their special attention to the antecedents to firms technology commercialization capability so far, forming a research stream on the antecedents. The goal of this study is to widen the research stream on the antecedents to SMEs technology commercialization capability. By constructing the research model for the mediating impacts of the product interior design and the testing and inspection capability and analyzing the 2,000 data from the SMEs in the Republic of Korea, this research provides the following implications. SMEs product interior design capability fully mediates the positive effect of the external technology collaboration network diversity on their technology commercialization capability and their testing and inspection capability partially mediates it. Futhermore, SMEs product interior design capability and testing and inspection capability jointly and fully mediate the positive effect of the external technology collaboration network diversity on the technology commercialization capability.
Improvement of Electrical Performance of InGaZnO/HfSiO TFTs with 248-nm Excimer Laser Annealing

The influence of 248-nm KrF excimer laser annealing (ELA) with energy density between 0 and 400 mJ/cm2 on the electrical behavior of indium gallium zinc oxide (InGaZnO) thin-film transistors (TFTs) is investigated. The experimental results show that the saturation mobility and subthreshold swing are improved from 12.4 cm2/Vs and 100 mV/dec without ELA to 17.8 cm2/Vs and 75 mV/dec, respectively, by applying a 300 mJ/cm2 laser pulse after the source/drain deposition, while maintaining an almost unchanged turn-off voltage. Such improvements are attributed to the increase in the oxygen vacancies and reduction in the bulk traps in the InGaZnO channel.

Magnetic resonance imaging (MRI) plays an important role for medical imaging technology in brain anatomical studies. Many automatic algorithms have been proposed for analyzing magnetic resonance imaging data sets. With the increasingly large data sets being used in mapping, there are some limitations of the manual algorithms, such as long computation time and issues regarding reproducibility. There has been a significant rise in the need for accelerating these algorithms. This paper handled the partial volume estimation (PVE), a brain tissue classification algorithm for MRI, on a field-programmable gate array (FPGA) as high performance reconfigurable computer using the Mitrion-C high-level language (HLL). FPGAs are very flexible and could achieve significant performance improvement by exploiting parallelism in processing. We used several simulated and real human brain MRI to evaluate the performance improvement of the proposed algorithm. The performance of probability density and prior information estimation implementation based on FPGAs achieved the overall speedup.

Under the background of inheriting national music culture, the inheritance and development of national music and regional culture has gradually attracted the attention of the society. As a cross-border ethnic group, Chinese Korean is one of the ethnic minorities with outstanding cultural traditions in the big family of the Chinese nation. In Korean traditional music, gayageum is a popular musical instrument with a broad mass base. Since the beginning of the new century, Korean gayageum art has been listed as "intangible cultural heritage" by the state, and people pay more and more attention to gayageum. With the spread of inheritance, gayageum inheritance activities are actively carried out in many fields of society, including primary and secondary schools at all levels. In many schools, the inheritance of traditional culture is an important part of school music education, and plays a key role in the inheritance of minority music culture. At the same time, it also faces some unfavorable problems, but leading talents with the excellence of this culture and the ability to popularize culture can solve this difficulty. For example, under the guidance of professional gayageum teachers, Xinxing Primary School in Yanji City inherited gayageum through extracurricular activities, and all students in the school gradually popularized the development of gayageum education model. This can improve students' national consciousness, master national music culture, improve national self-confidence and pride, and improve music accomplishment and overall quality. This study takes gayageum education in Xinxing Primary School in Yanji City as the starting point, analyzes the curriculum content, inherits and publicizes traditional culture by means of questionnaire survey and statistics, and tries to explore their achievements and inheritance status through the actual situation of gayageum in primary school music education.

The external technology collaboration network is of importance to increasing the performances in the technology development of the small andmedium-sized enterprises (SMEs). This study focuses especially on the influence of the external technology collaboration network diversity on SMEs’ production process improvement and cost reduction through technology development and themoderating effect of SMEs’ use of the external information on this influence. This study sheds a newlight on the three points based on the empirical analysis of the 2,000 data fromSouth Korean SMEs by using the ordinary least squares regression. First, SMEs’ external technology collaboration network diversity has a positive effect on their cost reduction through technology development. Second, SMEs’ production process improvement through technology development partiallymediates this positive effect of the external technology collaboration network diversity on the cost reduction. Third, the use of the external information for technology development moderates the effects of SMEs’ external technology collaboration network diversity on the production process improvement and the cost reduction.

Hau, Yong Sauk The Korea Society of Management Information System 2014 Asia Pacific Journal of Information Systems Vol.24 No.3
This study aims at empirically analyzing the relation between employees' personality and their knowledge sharing intentions, on which enough light has not yet been shed in spite of its importance. By integrating the big five model of personality with social capital theory and social cognitive theory, this study develops six hypotheses concerning the relation and empirically tests them by using 724 samples collected from employees in practice. The empirical analysis results from this study reveal that employees' extroversion and agreeableness are positively associated with their social relations and that their openness to experience and conscientiousness are positively associated with their knowledge self-efficacy, which are positively related to their knowledge sharing intentions. Based on the new findings, theoretical and practical implications are provided for knowledge management researchers and managers in practice.
