  • Many of the industrialized countries since the 1970s have been experiencing the change in the industrial structure due to technological development, that is, from Fordism to post-Fordism, or to "flexible production system". Regional development has been undergoing some changes according to the different industrial production systems. During the Fordist mass production period, the manufacturing belt was the core region of the production system. As the system shifts to flexible production system of which characteristics are veritcal disintegration, emphasis for JIT(just-in-time) delivery system, part-time and short-time labor contracts, design-intensive industries, etc, the new system requires the new production core and has produced the new industrial spaces, such as Sunbelt cities, suburbs, small-or medium-sized cities, and non-metropolitan areas. In the perspective of global system, the Fordist production system made th NICs developed, because the mass production required many unskilled and low-wage workers. As the NICs exports of manufactured goods have incredibly expanded during the 1970s, the industrialized countries have become threatened. The industriablized countries have restructured their economies and international policies. Such restructures resulted in the economic depression of the NICs. The investment pattern of the industrialized countries has changed and particularly those industries adopting the Post-Fordism have invested from the NICs to the peripheral areas of their own countries or toward the underdeveloped countries which have much lower wage workers. The investment pattern of the NICs is also undergoing some changes like from metropolitian areas to small or non-metropolitan regions. The regional development since the post-Fordist production is still going on, thus it is not possible to generalize the tendency. That could be a particular phenomenon or a stage in the long-term cycle. But the regional development in the world system since 1980s definitely shows the different pattern.t pattern.

  • Purpose: This study was performed to investigate the prevalence, morphology, and calcification pattern of the elongated styloid process in the Mathura population and its relation to gender, age, and mandibular movements. Materials and Methods: The study analyzed digital panoramic radiographs of 2,706 adults. The elongated styloid process was classified with the radiographic appearance based on the morphology and calcification pattern. The limits of mandibular protrusion were evaluated for each subject. The data were analyzed by using a Student's t-test and chi-squared test with significance set at p=0.05. Results: Bilateral elongation having an "elongated" type styloid process with a "partially mineralized" pattern was the most frequent type of styloid process. No correlation was found between styloid process type and calcification pattern on the one hand and gender on the other, although elongated styloid was more prevalent in older and male populations (p<0.05). Further styloid process elongation showed no effect on mandibular protrusive movement (p>0.05). Conclusion: Dentists should recognize the existence of morphological variation in elongated styloid process or Eagle syndrome apparent on panoramic radiographs. We found higher prevalence of elongated styloid process in the population of the Mathura region when compared with other Indian populations. The calcification of the styloid process was more common in the older age group with no correlation to gender, mandibular movement and site. "Type I" with a "partially calcified" styloid process was observed more frequently in the population studied.

  • The route of bony invasion and spread pattern of tumor in the mandible are important in management of gingival cancer. Ten patients with gingival cancer involving mandibular body region were operated by composite resection. The radiographic and histopathologic features of the mandibular invasion and spread were analysed and compared. Our results showed that histopathologic extent of tumor invasion were greater than the radiographic prediction, especially in width of the tumor. And the pattern of bony invasion in the body area was mostly found in transmedullary spread rather than perineural spread. The vertical involvement in the mandibular body with tumor was evaluated. It indicated that if a oncologic surgeon was to ensure an adequate safety margin for extirpation of tumor, in most cases, the maintenance of the mandibular continuity is difficult. If the mandibular involvement by gingival cancer was identified radiographically and clinically, segmental mandibulectomy was required for the adequate safety margin, in consideration of the spread pattern in the body area.

  • The purpose of this study is to analyze the sales area of gas stations to see the quality and the efficiencies of spatial distribution structure for petroleum products in Tae-jeon City. Location pattern of gas station is classified by factors of competitive facilities, transportation, population and landuse in Tae-jeon City. As a result, High profit pattern and low profit pattern is classified. The characteristics of the distribution pattern of gas station are that the while densely populated has a small sales area, the thinly populated region has huge ones. Location-allocation model is used in order to minimize the travel distance from consumer location to gas station and balance the spatial distribution of gas station in case studies. The result reveals that the model-based locations of gas stations are more dispersed and balanced in the whole Tae-jeon City compared with the actual location of gas stations. This study shows the characteristics and spatial distribution patterns of sales area and location in petroleum products distribution facilities.

  • In this dissertation, a new off-line recognition system is proposed using a subgraph pattern, neural network. After thinning is applied to input characters, balance having a noise elimination function on location is performed. Then as the first step for recognition procedure, circular elements are extracted and recognized. From the subblock HT, space feature points such as endpoint, flex point, bridge point are extracted and a subgraph pattern is formed observing the relations among them. A region where vowel can exist is allocated and a candidate point of the vowel is extracted. Then, using the subgraph pattern dictionary, a vowel is recognized. A same method is applied to extract horizontal vowels and the vowel is recognized through a simple structural analysis. For verification of recognition subgraph in this paper, experiments are done with the most frequently used Myngjo font, Gothic font for printed characters and handwritten characters. In case of Gothic font, character recognition rate was 98.9%. For Myngjo font characters, the recognition rate was 98.2%. For handwritten characters, the recognition rate was 92.5%. The total recognition rate was 94.8% with mixed handwriting and printing characters for multi-font recognition.

  • Cow image processing technique would be useful not only for recognizing an individual but also for establishing the image database and analyzing the shape of cows. A cow (Holstein) has usually the unique speckle pattern. In this study, the individual recognition of cow was carried out using the speckle pattern and the content-based image retrieval technique. Sixty cow images of 16 heads were captured under outdoor illumination, which were complicated images due to shadow, obstacles and walking posture of cow. Sixteen images were selected as the reference image for each cow and 44 query images were used for evaluating the efficiency of individual recognition by matching to each reference image. Run-lengths and positions of runs across speckle area were calculated from 40 horizontal line profiles for ROI (region of interest) in a cow body image after 3 passes of 5$\times$5 median filtering. A similarity measure for recognizing cow individuals was calculated using Euclidean distance of normalized G-frame histogram (GH). normalized speckle run-length (BRL), normalized x and y positions (BRX, BRY) of speckle runs. This study evaluated the efficiency of individual recognition of cow using Recall(Success rate) and AVRR(Average rank of relevant images). Success rate of individual recognition was 100% when GH, BRL, BRX and BRY were used as image query indices. It was concluded that the histogram as global property and the information of speckle runs as local properties were good image features for individual recognition and the developed system of individual recognition was reliable.

  • C-banded karyotypes of eight taxa of Korean Allium sect. Sacculiferum were examined by means of Giemsa techniques. Each of the taxa had their own characteristic bands. Most of the bands on the somatic metaphase chromosomes were mainly located on the short arm, intercalary region and medium sized chromosomes. In addition, the heterochromatic bands were usually facultative, recognized as two spots, and all investigated taxa had a pair of satellites of heterochromatin. The similarities of total length and number of bands revealed that three varieties of A. thunbergii G. Don have a closer cytological relationship than the others. The C-banding patterns of A. longistylum and A. linearifolium were examined for the first time in this study, and the former was clearly distinguished from the others by the distribution and number of its bands. The proportion of heterochromatic bands suggested that A. thunbergii var. thunbergii is the most primitive, and A. sacculiferum the most advonced, within the section.

  • This study was aimed at developing a new textile design based on the authentic and cultural resources of the Gangneung Subo pattern and applying the textile design to knitted fashion products. Gangneung has been recognized for its outstanding artistry in the field of Gyubang art. Gangneung Subo is an embroidered wrapping cloth. The discovered and preserved Subo at this time was from the Kwandong region centered in Gangeung, and is regarded as the product of the indigenous native culture in Kwandong. Therefore, as a representative cultural resource of Gangneung, the Gangneung Subo has sufficient value as a material for the development of cultural products with uniqueness, distinctiveness, and historicality. As a research method, the background of Gangneung Subo was investigated. A total of 12 motifs were created while preserving the authentic originality of the Gangneung Subo pattern and minimizing unwanted deformations of the pattern during the developing process. The created motifs were repeatedly applied to the pattern and new textile designs were created. Eighteen knit fashion products, including narrow and wide-width mufflers and neck warmers, were developed by applying the new textile designs. As a significant cultural resource for cultural goods development, this study ascertained the value of Gangneung Subo, preserving its unique distinction and history. This study was especially significant since the Gangneung cultural goods developed used knitted material and extended the development to producing real products.

  • Objectives This study was conducted to describe the regional malaria incidence in relation to the geographic and climatic conditions and describe the effect of altitude on the expansion of malaria over the last decade in Papua New Guinea. Methods Malaria incidence was estimated in five provinces from 1996 to 2008 using national health surveillance data. Time trend of malaria incidence was compared with rainfall and minimum/maximum temperature. In the Eastern Highland Province, time trend of malaria incidence over the study period was stratified by altitude. Spatio-temporal pattern of malaria was analyzed. Results Nationwide, malaria incidence was stationary. Regionally, the incidence increased markedly in the highland region (292.0/100000/yr, p =0.021), and remained stationary in the other regions. Seasonality of the malaria incidence was related with rainfall. Decreasing incidence of malaria was associated with decreasing rainfall in the southern coastal region, whereas it was not evident in the northern coastal region. In the Eastern Highland Province, malaria incidence increased in areas below 1700 m, with the rate of increase being steeper at higher altitudes. Conclusions Increasing trend of malaria incidence was prominent in the highland region of Papua New Guinea, while long-term trend was dependent upon baseline level of rainfall in coastal regions.
