This study was conducted among 831 industrial workers in Gumi City in Gyung-Sang-Buk Do for the purpose of acquiring knowledge to improve quality of life though industrial workers' oral health promotion. Oral examination and questionnaire surveying were used to evaluate workers' oral health state and subjective health state and analyze their effect on quality of life. 1. The number of workers in the study were 831 in all; there were more males who accounted for 74.6%. 43.7% of the subject were 29 years old, accounting for the largest age group. Their academic backgrounds are 53.6% workers who graduated from high schools or lower educational institutions, and 46.4% workers who graduated from college or higher educational institutions. 80.7% of the subjects replied that their economic state belonged to the middle class. Their job classification indicates that 70.2% were working in production and engineering fields and that the seniority of 55.3% workers was less than 55.3%. 2. The result of evaluating the effects of oral health state on individual well-being and quality of life using OHIP indicates that younger people, singles(p<0.01) than the married, those in worse economic situation and those with shorter seniority(p<0.01) had higher effect of oral health state on quality of life. In addition, those whose health or oral health was not good (p<0.01), those with liked tough texture of food and snacks(p<0.05), those with more frequency of drinking(p<0.01) and those with more smoking tended to have higher effect of oral health state on daily life or quality of life. Besides, OHIP confirmed that oral health state is a measurement tool that can evaluate its effect on individual well-being and quality of life. The suggestion for future studies is to develop Korean style OHIP that can be used conveniently and efficiently by expanding the subject area up to the whole country and validating the samples gained from random sampling.

Five winter and five spring wheat cultivars of diverse genetic backgrounds were evaluated to examine different developmental responses in terms of stages of the life cycle and grain yield when grown under the different planting dates. Greatest difference in growth and developmental patterns of the winter and spring wheat cultivars occurred in stem elongation, booting, inflorescence emergence and anthesis. The growth stage of stem elongation was found to exhibit larger difference both among planting dates and cultivars. Winter wheat cultivars responded more than spring wheat cultivars to the different planting dates. Winter wheat 'Cho Kwang' and spring wheat 'Jugoku 81' were earlier and exhibited faster growth and development, while winter wheats 'Yamhill' and 'Hyslop' were later in growth and development, but exhibited faster grain filling and higher rate of grain filling, resulting in higher grain yields. Crosses between winter and spring wheat gene pools would result in earlier maturity and higher productivity for both winter and spring wheat cultivars. For developing early maturing wheat cultivars for multiple cropping sequences while maintaining productivity, selection for earliness trait should be started at the stem elongation stage. Furthermore, the breeding materials should be planted at several times for selection of shorter life cycle genotypes adaptable to the cropping sequences. This is due to the genotype x planting date interactions.

This study's objective is to inform people of the value and identity and to understand the cultural landscape characteristics of coastal village forest, which have not been studied in-depth in previous studies. This study was conducted by selecting 10 village forest sites in the southern coast of Gyeongsangnam-do, Korea and the present state of forests were investigated through bibliographical and on-the-spot survey, as well as interviews with local villagers. The following points(characteristics of traditional culture, practical characteristics, scenic characteristics) are the important factors for analyzing cultural landscape characteristics of coastal village forest verified through the study. First, The coastal village forest in the village commons is mental space for the local community affected by folk belief rather than confucian backgrounds. Second, The coastal village forest is a reasonable space contriving economic efficiency and solving the real problems facing the coastal village. Third, The coastal village forest identities should be understood the land use around village and behind mountain from the sea of wide range rather than confined to just a forest consisting of trees. This study's significance is to make the basic data and to enhance the value of the coastal village forest unnoticed. In addition, the subjects of the study should be extended to the east and west coastal village forests and subsequent research should be conducted to notification the characteristics and differences of each coastal village forest.

Agrobacterium tumefaciens-mediated transformation procedure for the phalaenopsis orchid, established by using Protocorm-like bodies (PLBs), was aimed at the introduction of target genes into individuals with divergent genetic backgrounds. PLBs obtained from the axillary bud of a peduncle were maintained on a hyponex medium supplemented with 1 g/l of activated charcoal, 30 g/l of sucrose and 0.1 mg/l thiamine. The multiplication rate of PLBs was about 90% in case of subculture PLBs to be cut transversely into 1/3 part from top position. The PLBs were inoculated with Agrobacterium strain EHA105 harboring both $\beta$-glucuronidase (GUS) and hygromycin-resistant genes for 20 minutes after dipping treatment. Transformation efficiency was the highest with a Agrobacterium culture medium and dipping treatment of O.D. 0.8. Newly induced PLBs were put on selection medium containing 1 mg/l hygromycin for 2 months. Hygromycin-resistant phalaenopsis plants that regenerated after the selection culture of PLBs showed histochemical blue staining due to GUS. Transgene integration of the hygromycin-resistant plants was confirmed by PCR and Southern blot using GUS specific primers and probe.

This paper presents a method to segment the object of interest from a set of multi-view images with minimal user interaction. Specifically, after the user segments an initial image, we first estimate the transformations between foreground and background of the segmented image and the neighboring image, respectively. From these transformations, we obtain regions in the neighboring image that respectively correspond to the foreground and the background of the segmented image. We are then able to segment the neighboring image based on these regions, and iterate this process to segment the whole image set. Transformation of foregrounds are estimated by feature-based registration with free-form deformation, while transformation of backgrounds are estimated by homography constrained to affine transformation. Here, both are based on correspondence point pairs. Segmentation is done by estimating pixel color distributions and defining a shape prior based on the obtained foreground and background regions and applying them to a Markov random field (MRF) energy minimization framework for image segmentation. Experimental results demonstrate the effectiveness of the proposed method.

This study was to elucidate the theoretical backgrounds and realities of consumer health information services from a review of the literature, to manifest the actual conditions of consumer health information services by domestic hospital libraries and public libraries, and then to activate library services at least to meet the needs of the services by enhancing their role for consumer demand for health information. This paper propose to activate consumer health information services, as follows : First, librarians both in hospital and in public libraries cognize that consumer health information services really are needed. Furthermore, they expect that when consumer health information services are implemented, the function of the library would be expanded even to the realm of preventive health medical care for consumers and as well as to the patients' right to know. Second, it is recommended that hospital libraries should actively perform their consumer health information services, along with the active collection of health information and materials and develop related bibliographies for hospital libraries to provide patients and their families with medical information. Public libraries also are required to actively collect, maintain and manage health information and to equip themselves with special books in their reference rooms. Third, it is recommended to launch such a cooperation network with a subsystem of MEDLIS as CHIN or CHIPS in the United States of America, to construct an integrated database of consumer health information and materials, an interlibrary system, a reference room service system as well as a cooperation network among hospital and public libraries.

This paper proposes the MAWUPC (Motion Adaptive Weighted Unmatched Pixel Count) algorithm to track multiple objects of similar color The MAWUPC algorithm has the new method that combines color and motion effectively. We apply the MAWUPC algorithm to face and hand tracking against complex background in an image sequence captured by using single camera. The MAWUPC algorithm is an improvement of previously proposed AWUPC (Adaptive weighted Unmatched Pixel Count) algorithm based on the concept of the Moving Color that combines effectively color and motion information. The proposed algorithm incorporates a color transform for enhancing a specific color, the UPC(Unmatched Pixel Count) operation for detecting motion, and the discrete Kalman filter for reflecting motion. The proposed algorithm has advantages in reducing the bad effect of occlusion among target objects and, at the same time, in rejecting static background objects that have a similar color to tracking objects's color. This paper shows the efficiency of the proposed MAWUPC algorithm by face and hands tracking experiments for several image sequences that have complex backgrounds, face-hand occlusion, and hands crossing.

The purpose of this study was to examine the level of information literacy of the marriage immigrant gatekeepers in Korea. To do this, 51 gatekeepers who live in Busan and Gyeongnam Province were surveyed and the result was compared with the result of another study that was conducted regarding 189 ordinary marriage immigrants living in Busan and Gyeongnam Province in 2009 and used the same survey instrument. As a result, the level of information literacy of the gatekeepers was superior to that of the ordinary marriage immigrants. Also, 14 gatekeepers were interviewed to investigate how they had higher level of information literacy than that of ordinary marriage immigrants. Through analysis of the interviews, "information use environments of the mother country" didn't support their information literacy, but "higher education level", "Korean language skills and bilingual/multilingual abilities", "experiences of information literacy education", "information-friendly home environment", "positive attitude toward life and active social participation" and "active utilization of several information service providers and media" could be the backgrounds of higher information literacy of the marriage immigrant gatekeepers. At the end of this study, some suggestions are made for improving the information literacy of the ordinary marriage immigrants.

To restore urban water cycle, it is necessary to improve domestic laws and regulations related to LID(Low Impact Development), which has been successfully applied to foreign countries. Thus, this study has intended to evaluate domestic legal systems related to space and environmental planning and to suggest directions to improve laws and regulations related to space and environmental planning toward extended application of LID in Korea. To reach this goal, this study has analyze the legal and institutional status of the foreign countries where LID has currently been applied, to derive the factors that laws and institutions are required to support LID based on the above analysis, to evaluate domestic laws and regulations related to space and environmental planning, and to suggest directions to improve the laws and regulations. After the evaluation, this study has found the following results. First, it was found that the concept and basic principles of LID and LID planning and associated methods were no longer mirrored in the space planning-related laws and regulations. However, these problems are not confined to LID, and result from thefailurein applying environmental planning to space planning overall. Second, it was revealed that the environmental planning-related laws and regulations defined the terminologies and targets of LID and suggested different measures to improve LID-related policies differently depending on the backgrounds ofenforcing thelaws and regulations and on environmental properties. Finally, this study has suggested the directions to improve laws and regulations related to space and environmental planning as follows. First, it is necessary to enact a law to support the extended application of LID. Second, the law to be enacted should be connected to laws, enforcement ordinances and regulations, and guidelines related to space planning. Third, environmental benefits provided by both structural and non-structural techniques of LID should be quantitatively measured.

This study was aimed to investigate the distribution status and phylogenetic relationship of Myotis aurascens in Jeju Ialnd, which has not clearly confirmed until now. We found three groups of M. aurascens from three different cave enforcements (CEs). The bat population of Jeju Island had smaller levels of HBL and Hfcu, but greater levels of TL, EL, FAL, and Tra than those of the Korean Peninsula population. Jeju bats had wide range in the lengths of FAL and Hfcu comparing to those of European bats. From the bimonthly monitoring to each finding site, we have actually failed to observe those again, estimating that they use those CEs as the daily-roosting place in activating seasons. The sequences of CYTB and COI genes showed identical sequences among Jeju bats tested, indicating that they are maternally related. The results from molecular phylogeny showed that the sequences of these bats located on the same branch with those for M. aurascens in the phylogenetic trees. Besides, the nucleotide sequences of the Jeju bats showed the closest relation with that of Korean Peninsula. Consequently, these findings indicate that the bats of M. aurascens, verified the natural distribution in Jeju Island, have originated from a single maternal origin and differences in morphological and genetic backgrounds form those of Korean Peninsula and the other countries, and had probably immigrated via Korean Peninsula. These findings will contribute as basic information for understanding the migration history and biogeographic relationship of mammals on Jeju Island in East Asia.
