  • This paper describes an approach to detect interesting objects using satellite images. This paper focuses on the interesting objects that have common special patterns but do not have identical shapes and sizes. The previous technologies are still insufficient for automatic finding of the interesting objects based on operation of special pattern analysis. In order to overcome the circumstances, this paper proposes a methodology to obtain the special patterns of interesting objects considering their common features and their related characteristics. This paper applies MSER(Maximally Stable Extremal Regions) for the region detection and corner detector in order to extract the features of the interesting object. This paper conducts a case study and obtains the experimental results of the case study, which is efficient in reducing processing time and efforts comparing to the previous manual searching.

  • The relation between light sources and screen cells is considered part of the theoretical model of an autostereoscopic 3D display. The geometry of the image and observer regions is presented, including the cases of single and multiple regions. The characteristic function is introduced. Formulas for the geometric parameters are obtained, including areas and angles. Special attention is drawn to the screen location. The method of transforming the formulas between regions is stated. For multiple regions, geometric dissimilarity was found. This allows the model to be applied in finding the geometric characteristics of multiview and integral-imaging 3D displays.

  • The methods for implementing geocentric to geodetic coordinates conversion could be classified into two, which are respectively the closed-form and the iterative-form solutions. Essential conditions to achieve performances are accuracy, speed of convergence and/or simplicity of it's algorithm. Also, the algorithm must be valid at any of inner and outer points in the Earth, including center of Earth, the equatorial plane and the polar axis that are known as 'special regions'. This research planned for evaluating the feasibility of coordinates conversion in special regions, and comparing the accuracy of conversion solutions by using 10 methods for conversions from geocentric to geodetic coordinates. By comparing performances of statistical tests(with accuracy and solving success in special regions), Vermeille(2011) and Karney(2011) methods brought out more satisfied and finer results than other methods.

  • R.O.C. has experienced successively the development of previous dynasties that creates out the unique traditional culture of each stage. The Chinese nation is not a one-fold race; each dynasty absorbs the culture of the outside race. It is Tang Dynasty blends mutually however yield unusually brilliant results. The Tang Dynasty's national strength is forceful and the economy is prosperous. Above all, social custom and current of thought both break the constraint of previous dynasties' conservative thinking and keep positive and aggressive. While in the contact with extraterritorial culture, not only changes the feminine social status, but also produces unprecedented innovation and reform on the feminine dress. The Tang Dynasty's varied feminine suit is affected by the western regions of China culture, such as expose of chest, low collar, short top garment and skirt with narrow sleeves or wide sleeves, sleeve gown with plate collar or turndown collar, man's wear, and military dress, etc. An epoch can be known by Tang Dynasty feminine dress's special features, for example, the make-up of Tang-Shien-lon's Uan-Ho period presents dress style of late Tang days. However, the Chinese people compete mutually pursuing the strange costume, and accepting different cultural incitement This reveals that the changes of popular culture would result in the big transform of the Tang's dress style. This paper studies inherit of Tang Dynasty's culture and east-spread of the western regions of China culture. While understanding the Tang's favor in the western regions of China customs, all follow the western regions of China without exception, such as dance music, painting, dress, food, amusement, etc. Because of emperor's progressive race policy and forgiveness attitude to the foreign tribe that makes Tang Dynasty's feminine dress much easier to accept and blend the special features of the foreign tribe culture. While joined with west culture, and pick the dress's essence of the western regions of China, the original possessed of culture consciousness and esthetic sense improve and create their own dress, as well as enrich more inner part of dress art and the spirit.

  • This study was carried out for preliminary feasibility review to investigate work efficiency of chestnut harvest using yield net and to find a way to reduce the cost for purchasing and managing yield net. To this end, we conducted a survey of 6 forest farm houses in Cheongyang, Gongju and Buyeo regions where yield nets are being used efficiently. Cost-benefit analysis based on Net Present Value and Benefit Cost Ratio was used to examine the investment profitability. While regions of Cheongyang A, Cheongyang B and Buyeo A are profitable in spite of no subsidy for purchasing yield net from the government, the regions of Gongju A, Gongju B and Buyeo B are not profitable without subsidy. When an 80% of subsidy for purchasing yield nets is provided, the forest farm houses in Cheongyang A, Cheongyang B, Buyeo A and Gongju B regions are found to be profitable while those in Gongju A and Buyeo B regions are still not profitable. We consider that the different results come from the differences in the planting method of chestnut, labor efficiency, labor skill and the orchard conditions such as slop. Finally, several efforts for government and cultivator are suggested to expand the use of yield net; planting chestnut in line, establishing installation and management methods, supporting the cost for purchasing yield net and studying detailed effects besides profitability issue.

  • This study was conducted to investigate the effects of region and age on nut quality of major chestnut cultivars (Castanea spp.) cultivated in the central region of Korea to provide basic data for nut quality control and processing of postharvest. In the survey of by regions and ages, Buyeo and 'Hyogo57' showed the highest value by regions and cultivars, respectively. Also, there were statistically significant differences among regions and cultivars in the value of soluble solid content and kernel hardness. In the soluble solid content, Gongju showed the highest value among regions, and 'Tsukuba' among cultivars was the highest, 20.5%. Cheongyang showed the highest value of kernel hardness among regions, and 'Tanzawa' among cultivars showed the lowest value of kernel hardness, $8.75kg/cm^2$. In 'Tanzawa', 'Okkwang' and 'Tsukuba', soluble solid content and kernel hardness showed statistically significant differences according to age, but no correlation with age.

  • Our government finally understood the true meaning of this wisdom and is attempting to revive the rural area by establishing local produce exhibition hall. This is to allow different regions to promote their specialties and provide diverse experience to the public. However, the reality is that unstructured marketing and PR is not achieving much. Marketing in the past was a paradigm of function and benefit. As we passed 20th century, this was challenged, leading to experiential marketing. Customers' cultural urge and interest in experience and participation are getting stronger. With the facilitation of Promotion Center for local special products, local special products and relevant local communities will be promoted, and the distribution business will grow further. This research was performed to establish basic research materials for planning information center in order to invigorate regional products. This study brought about the following results: first, the Promotion Center for local special products can acquire emotional elements by associating the elements with local special products; secondly, the Promotion Center for local special products can acquire cognitive elements by harmonizing local communities' unique identities with their own other special products; thirdly, the Promotion Center for local special products can acquire behavioral elements by enjoying various experiences and events; fourthly, the Promotion Center for local special products can acquire relational elements by integrating other new spaces.

  • Indonesia's most eastern provinces enjoy special autonomy status but still suffer from the highest poverty level in the entire nation. Using the Williamson index to test the Simon Kuznets theory, this study examines development equality at pre-and post-special autonomy in the provinces of Papua and West Papua. It uses gross domestic products per capita and population from 29 regencies/cities in Papua and 13 regencies/cities in West Papua to measure the Williamson index in addition to in-depth interviews with legislative members and document analysis to validate the findings. The study found that the regional development gap before special autonomy is relatively smaller than that existing after special autonomy. The Kuznets' curve is not proven in the special autonomy era, meaning that the imposition of autonomy status has led to the creation of a higher development gap in these provinces. Although the special autonomy status has prompted an increased opportunity for political participation by the indigenous people, greater challenges are posed by the lack of human resources, poor government administration, difficult geographical access and the issue of land acquisition. Continuous development initiatives followed up with adequate supervision, greater transparency and law enforcement from government bureaucrats and legislatures are recommended to reduce the inequality.

  • This study was conducted to compare the postharvest physiological characteristics of 2 paprika cultivars; 'Special', 'Fiesta' grown in 2 regions: Chuncheon(plain region) and Hwacheon(semi-high land region), and by 2 cultural methods; soil and hydroponic(rock wool culture). Respiratory rate of paprika fruit was higher in soil culture, and ethylene production was higher in Chuncheon region of both cultivars. As the thickness of fruit flesh showed thicker in Hwacheon region and hydroponic culture, the firmness of fruit was in proportion to thickness. Vitamin C content was higher in red-cultivar, 'Special'. and in Chuncheon region. Soluble solids was higher in 'Special', but there was no different between cultural regions. The fruit of both cultivars was grown smaller in Chuncheon region, and the fruit shape of 'Fiesta' progressed faster in soil culture. The surface color of fruit was higher in Hwacheon, and although there was no significantly different between cultural method, both cultivars grown by hydroponics was shown vivid color. As above results, for the long term circulation and high quality of fruit, paprika may be cultivated by hydroponics in high-altitude region.

  • In this paper, an effective digital watermarking method for copyright protection of binary image data is proposed. First a binary image is grouped into feature regions which has geometrical features and general one. The watermark for authentication is embedded in general regions in order to preserve geometrical features regions. We have used run-length code and special runs for grouping feature regions and general one. For invisibility of watermark, we have embedded the watermark considering transition sensitivity of each pixel in general regions. The proposed method is applied some binary image such as character, signature, seal, and fingerprint image to evaluate performance. By the experimental results, the proposed method preserve feature regions of original image and have higher invisibility of watermarks.
