In this paper, we propose a new fast Hough transform to improve the processing time and line detection of Hough transform that is widely used in various vision systems. First, for the fast processing time, we reduce the number of features by using multi-statistical methods and also reduce the dimension of angle through six separate directions. Next, for improving the line detection, we effectively detect the lines of various directions by designing the line detection method which detects line in proportion to the number of features in six separate directions. The proposed method was evaluated with previous methods and obtained the excellent results. The processing time was improved in about 20% to 50% and line detection was performed better in various directions than conventional methods with experimental images.

The Farm Household Economy Survey (FHES) is carried out by the Ministry of Agriculture and Forestry every year. In this paper, we reveiwed the current status of the FHES and assessed the precision of the survey results. Finally we proposed some recommendations for improving the precision and presented the improvable directions of FHES with some feasible solutions.

This study aims to figure out what kind of competences Chinese teachers need when teaching foreigners Chinese and if there is a difference between the importance degree they cognise and the practical level they keep, which could help to indicate improving directions of teachers' cultivation and training. To achieve this purpose, we chose 56 in-service Chinese teachers in Q City, Shandong Province, China as the subject of investigation. As results of this study, about the importance degree of competences of teaching foreigners Chinese, the average score is pretty high, which could assure the competences Chinese teachers need, but as for practical level, the average score is relatively low, which could help to assure the improving directions. In conclusion, competences of teaching foreigners can be divided into knowledge, skill and attitude. To improve the practical level of Chinese teachers, it's necessary to attach more importance to Chinese culture, methods of language education, cross-cultural adaptation, research on teaching and so on in Chinese teachers' cultivation and training programs.

This paper presents the laser processing to adjust the roll and pitch directions of the flex suspension assembly for hard disk drive production. The adjustment is accomplished using a number of laser beam projections that can be approximated using the regression model of the existing measured roll and pitch directions. Information derived from the analysis can be applied to control the quality of flex suspension assembly. The performances of the proposed technique were observed using the flex suspension assembly plant in Thailand as an illustrative case study. The experimental results are given to support the improving manufacturing yields and some economic benefits of the proposed technique.

We have studied electro-optic characteristics to improve viewing angle of the in-plain switching (IPS) liquid crystal display using an compensation film. The IPS mode shows relatively large light leakage and color shift in diagonal directions in a dark state. To solve this problem, we have compensated the low contrast ratio in diagonal directions using one optimized discotic film and adjusting TAC films of polarizers. The compensated IPS mode shows wide viewing angle characteristics that region of CR 50:1 is over $60^{\circ}$ of polar angle in all directions. The optimized IPS cell exhibits much better performances than other methods do in terms of CR and color uniformity.

Seismic resilience (SR) plays a vital role in evaluating and improving performance losses along with saving repair costs of structures from potential earthquakes. To further explore the developments, hotspots, and trend directions of SR, a total of 901 articles are obtained from the Web of Science (WoS) database. CiteSpace software is used to conduct a bibliometric analysis, which indicates an upward trend of publications in SR and explores the relationship of countries, journals, cited references, and keywords based on visual maps and detailed tables. Then, based on the results of the bibliometric analysis, a state-of-the-art review is conducted to further explore the current challenges and trend directions of SR. The trend directions can be divided into five categories: (a) SR assessments of infrastructure structures, (b) multi-hazard quantifications of SR, (c) seismic resilient structures, (d) refining and calibrating analytical models, and (e) multi-criteria decision-making frameworks for sustainability and SR.

The research investigates the changes of current government policy for Micro-enterprises with respect to the government policy fund, start-up, management education and the relevant consulting services. The examination is used for providing the improving directions of Micro-enterprise government policy reflecting on the current Micro-enterprises. While Micro-enterprise belongs to the class of Small enterprise, the impact of the government policies in Micro-enterprise is much bigger than the other. For this reason, the fundamental investigation considering Micro-enterprise is crucial. In order to provide the improving directions, this research examines the incumbent government policies. Then, the analyses provides the changing agenda for Micro-enterprise. The suggestions contributes to the improving criteria for right paradigm of Micro-enterprise.

This paper proposes strategy development to improve the management of Multicultural Family Support Centers by analyzing four Multicultural Family Support Centers (MFSCs) in Chungcheongnam-do. The research was conducted from September 2012 to January 2013. Future directions for the four MFSCs are established based on a SWOT analysis on both the internal and external environments of the centers. Various strategic directions for the four MFSCs were identified based on these analyses. For center A (urban type, college contract type), the strategic directions included the specialization strategy, systemization strategy, empowerment strategy, standardization strategy, and achievement maximization strategy. The strategic directions for center B (urban-rural combined type, social welfare center contract type) included the improvement of multiculture awareness, specialization strategy, human resource development strategy, and networking strategy. For center C (farming and fishing community type, direct management type by local authority), the strategic directions included the specialization strategy, activation strategy, qualification strategy, and networking strategy. For center D (farming and fishing community type, social welfare center contract type), the strategic directions included the specialization strategy, business standardization strategy, human resource development strategy, and network expansion strategy. The suggested management strategy development for the four MFSCs can provide implications for the management of MFSCs in other areas in Korea.

This paper proposes a new algorithm for improving the performance of the spatial filter which is the most important part of deinterlacing methods. The conventional edge-based algorithms are not satisfactory in deciding the exact edge direction which controls the performance of the interpolation. The proposed algorithm much increases the performance of the intrafield interpolation by finding exact edge directions based on the binary image. Edge directions are decided using 15 by 3 local window to find not only more accurate but also many low-angle edge directions. The proposed interpolation method upgrades the visual quality of the image by alleviating the misleading edge directions. Simulation results for various images show that the proposed method provides better performance than the existing methods do.
