As the importance of rural landscapes has recently emerged due to an increase in number of urban to rural migrants into suburban area in Korea, this study empirically grasps the differences in subjective landscapes perceptions between native and non-native residents. and tried to explore new landscape management possibilities through the role of each residents group. To this end, based on the data collected through the 'photo-elicitation with walking', the residents' landscape perception objects, perception factors, and perceived feelings are derived, and then the differences and characteristics of landscapes perception between native and non-native residents group were analyzed. As a result, native residents perceived everyday landscapes relatively meaningfully and provided abundant information in all aspects, while non-native residents mainly recognized characteristic landscapes and responded more sensitively to visual and environmental perception factors than the natives. Non-native residents also showed strong willingness to improve the degraded landscapes. These results are expected to provide a basis for exploring the role of residents in rural landscape planning and management in the future.

The aim of this study was to analyze the genetic diversity and distance of the Korean native black goat line. Thus far, this Korean native black goat line has not been studied intensively, especially in genetic diversity and relationship studies in comparison with other breeds. In total, eleven microsatellite (MS) markers were used to evaluate alleles from 391 Korean native black goats and foreign hybrid animals. The genetic diversity index was evaluated based on the allele distributions. Four Korean native black goat lines showed expected ranges of observed heterozygosity, expected heterozygosity, and polymorphism information content (PIC) values for use in genetic diversity research (0.509 - 0.643, 0.434 - 0.623 and 0.356 - 0.567). Lines from the Korean native black goat and foreign hybrid were clearly separated according to principal coordinates analysis (PCoA), phylogenetic tree and tended to be clustered in each Korean native black goat line. Thus, this study can be used for analyzing the genetic relationships between Korean native black goats and foreign breeds for line preservation and for fundamental information to determine breed improvement strategies.

Rather than focusing on the general recognition of the area and extensive preference about its native cuisine, this study carried out more practical examination on the recognition of the native cuisine by presenting the more detailed introduction of the native cuisine in Hadong area. The findings of this study can be used as basic materials to devise measures for the instillation and advertisement of Hadong area's image, the development and maintenance of its native cuisine benefiting the activation of the local economy, and the reestablishment of Hadong area's native cuisine culture. First, the overall recognition of Hadong area's native cuisine was low and more consumption needs to be boosted by merchandising its foods through the strengthening of recognition. Second, correlation between this area's native cuisine was revealed and tables need to be set and menus need to be organized with this correlation in mind. Basic materials for suggestion sale were garnered. Third, given that most outside tourists visit Hadong by word mouth of all the information sources available, it is highly likely that positive word of mouth through satisfaction with native cuisine will raise the overall recognition of the area. Fourth, precise subdivision market and target market need to be specified. Though the factors like economic costs and the time required cannot be overlooked in strengthening recognition, consistent advertisement to the middle-aged people who are over 40 and live in Kyungsang-Do area will contribute to the fast rise in the recognition of Hadong area's native cuisine, leading to the possibility of economic development in the process.

The object of this experiment was to investigate the food habits of Korean native goats fed with various roughage sources. The experimental trials were conducted at Unbong Animal Genetic Resources Station in 2008. The experimental roughages include five sources and 25 species in all; grasses and legumes: 5 species (mixed grasses, orchardgrass, tall fescue, alfalfa, white clover), native grasses and weeds: 5 species (mixed native grasses, Miscanthus sinensis Anderss, Arundinella hirta (Thunb.) Tanaka, Barnyard grass, short awn, forage crops and straw: 5 species (barley + hairy vetch, wheat + hairy vetch, rye silage, barley silage, baled rice straw), browse and fallen leaves: 5 species (Mixed browse, Oriental white oak, Quercus serrta Thunb., Oriental cherry fallen leaves, Japanese chestnut fallen leaves), and imported hay and straw: 5 species(timothy hay, tall fescue straw, annual ryegrass straw, klinegrass hay, alfalfa hay). Ten Korean native goats were selected which had nearly the same body weight (average $24{\pm}2.8$ kg). The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period (p<0.05). Among all the 25 species of roughages, the favorite intake species order by Korean native goat was observed like this: Quercus aliena, Querancas serrta Thunb and Mixed browse, which was a lower intake compared to other domestic herbivores. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. On the other hand, compared to each roughage source, total intake amount by Korean native goats was showed as browse and fallen leaves (33.1%) among trials roughage sources. Based on these results, the food habit of Korean native goats seems to be closer to the browser.

Goats (Capra hircus) are one of the oldest species of domesticated animals. Native Korean goats are a particularly interesting group, as they are indigenous to the area and were raised in the Korean peninsula almost 2,000 years ago. Although they have a small body size and produce low volumes of milk and meat, they are quite resistant to lumbar paralysis. Our study aimed to reveal the distinct genetic features and patterns of selection in native Korean goats by comparing the genomes of native Korean goat and crossbred goat populations. We sequenced the whole genome of 15 native Korean goats and 11 crossbred goats using next-generation sequencing (Illumina platform) to compare the genomes of the two populations. We found decreased nucleotide diversity in the native Korean goats compared to the crossbred goats. Genetic structural analysis demonstrated that the native Korean goat and cross-bred goat populations shared a common ancestry, but were clearly distinct. Finally, to reveal the native Korean goat's selective sweep region, selective sweep signals were identified in the native Korean goat genome using cross-population extended haplotype homozygosity (XP-EHH) and a cross-population composite likelihood ratio test (XP-CLR). As a result, we were able to identify candidate genes for recent selection, such as the CCR3 gene, which is related to lumbar paralysis resistance. Combined with future studies and recent goat genome information, this study will contribute to a thorough understanding of the native Korean goat genome.

The study was attempted to scrutinize the normal osmotic fragility of erythrocyte in the domestic ruminants, making a comparison with that of human and canine. The animals used in the experiment were apparently healthy adult Holstein cattle, Korean native cattle, sheep (Corriedale) and Korean native goats. Osmotic fragility of erythrocytes was the highest in the Korean native goats, and the next were sheep and Korean native cattle, and Holstein cattle in order. In other words, erythrocytic resistance to osmotic lysis was the strongest in Holstein cattle and the most weak in Korean native goats among the domestic ruminants. In general, resistance of erythrocytes was stronger in human and canine than in the domestic ruminants.

Much research attention has been directed to identify how native speakers perceive non-native speakers' oral proficiency. To investigate the generalizability of previous findings, this study examined segmental, phonological, accentual, and temporal correlates of native speakers' evaluation of L2 Korean proficiency produced by learners with various levels and nationalities. Our experiment results show that proficiency ratings by native speakers significantly correlate not only with rate of speech, but also with the segmental accuracies. The influence of segmental errors has the highest correlation with the proficiency of L2 Korean speech. We further verified this finding within substitution, deletion, insertion error rates. Although phonological accuracy was expected to be highly correlated with the proficiency score, it was the least influential measure. Another new finding in this study is that the role of pitch and accent has been underemphasized so far in the non-native Korean speech perception studies. This work will serve as the groundwork for the development of automatic assessment module in Korean CAPT system.
