  • Mt. Taegi (1,261.4 m) located in Gangwon-do, is a geographically important region for plant biodiversity. But the biodiversity of Mt. Taegi has been seriously damaged by the invasion of foreign plants, the development of forests and so on. We conducted 21 field surveys between April and August in 2008 and March and October in 2018 to investigate the vascular flora in Mt. Taegi. Total 662 taxa were identified including 96 families, 338 genera, 580 species, 4 subspecies, 66 varieties and 12 formas. Among them, 28 taxa were Korean endemic plants and 8 taxa were rare plants designated by the Korea Forest Services, and 11 taxa were listed on the Red list of endangered plants and 127 taxa were designated as the floristic regional indicator plants according to the Ministry of Environment. The alien plants were 45 taxa, including R. acetosella that is the ecosystem disturbing species.

  • The petal and sepal micromorphology of five species of Glechoma (Lamiaceae) was investigated to evaluate their taxonomic significance, and a molecular phylogeny using the sequences of internal transcribed spacers (ITS) regions of nuclear ribosomal DNA was carried out to resolve their phylogenetic relationships. Stomatal complexes were mostly found in the inner and outer part of the sepal from all investigated taxa, and the size length of the guard cell was variable among the taxa. Five types of trichomes (uni-cellular non-glandular trichome, multi-cellular non-glandular trichome, short-stalked capitate glandular trichome, long-stalked capitate glandular trichome, and peltate glandular trichome) were variable among the taxa as well as their distribution and density. In molecular phylogenetic studies, the genus Glechoma was composed of three geographically distinct major monophyletic groups (Europe-U.S.A., China-Korea, Japan). G. longituba in Korea and China formed well-supported monophyletic group. G. hederacea in Europe and U.S.A. formed a monophyletic and well-supported clade with G. sardoa, which are endemic species in Italy, with G. hirsuta falling as a sister to this clade. However, G. grandis did not form any phylogenetic relationships with the remaining taxa. The ITS analyses provided taxonomic boundaries of taxa in Glechoma although the petal and sepal micromorphological characters provided weak evidences of the systematic value. As further studies, incorporating more DNA regions to the matrix including other additional morphological analysis will be significant to provide clearer taxonomic structure in Glechoma.

  • Genetic variation in Asaum misandrum, a woodland herb in Korea, was investigated based on allozyme analysis with starch gel electrophoresis. All of previously reported populations in Korea were sampled and seven loci from six enzymes were analyzed. Overall genetic variation of A. misandrum population showed considerably high levels of genetic variation within the species (A = 2.05, P = 71.4, $H_E$ = 0.294). A positive $F_{IS}$ value of A. misandrum indicated overall deficiency of heterozygotes, and a low $F_{ST}$ value (0.112) meant very little differentiation among populations. Factors contributing to the high levels of genetic diversity found within populations of A. misandrum include population maintenance via wide distribution range from Korea to Japan and primarily outcrossing breeding system. Although it showed moderate genetic diversity level, most habitats of the species were scattered and discontinuous. Besides, low numbers of individuals were found in the most habitats and individuals are collected frequently from the wild due to the unique shape of the flowers as well as the rarity of the species. Thus, there is a need to set up a reasonable conservation strategies including the maintenance mechanism of genetic diversity of A. misandrum.

  • The conservation status of an endemic perennial herb, Hanabusaya asiatica (Nakai) Nakai (Campanulaceae) was determined by applying the IUCN risk assessment criteria from our field study and available specimen data. Also, the GIS technology was used to develop a species distribution map to calculate the extent of occurrence (EOO) and area of occupancy (AOO) for the taxon. After two years of continuous field studies, 269 mature individuals were found in four localities in 2011, while 216 mature individuals were confirmed in three localities in 2012. Based on the following data, such as EOO (2,742 $km^2$), AOO (76 $km^2$) and estimated population size of mature individuals, the taxon, which is known as 20 localities in Korean peninsula, is evaluated as the category of Endangered (EN). A major difficulty in application of IUCN criteria to Korean rare plants were the lack of essential biological information and understanding the correct knowledge of the IUCN criteria in previous Korean studies. Sound conclusions regarding the conservation status of individual species require more intensive population studies, observations, and applying IUCN assessment procedures correctly.

  • With the increase of visitors to rural tourism villages, the direct selling at sites is getting vitalized. Accordingly, their display stores is getting more important. Therefore, this study has selected 30 domestic rural tourism villages as study objects for the attitude survey of 200 farming suppliers and the site examination for the designs of those display stores in order to analyze their status and classify the types of necessity. Such operation status as sale item, sale method, method of supply and demand, major customer, sales scale, manager, opening hour, and operation cost were examined, to identity and for design factors the pattern, material quality and color were investigated. For the attitude of farming suppliers, the tactics of sales, the reason for being positive or negative, the functionality and the features of display stores were examined through brainstorming. IBM SPSS Statistics 20 Program was employed for Frequency, which indicated that village chiefs and store managers with the sales scale of 1 to 20 million won are dealing with female customers in their 40's and 50's and that those stores are open at the time of experience or year round without any operation expense. Permanent type and Fixed type were found to be the design factors of the display-case type with the material and the color of wood and orange respectively. The result of investigation analysis of farming suppliers' attitude showed the followings: the need of display stores is quite high, structure type and permanent type have high fitness and from the viewpoint of display-on-table type as a standard moving type was very convenient. The analysis of significant items at the characteristics of those display stores revealed that their locations, quality conservation, sanitation, users' convenience, designs and promotion are very important. The result of status analysis revealed that though there is a correlation among the types of display stores depending on the visiting season of tourists their installing is not desirable. Three types have been analyzed: Type 1 is a structure type only in the villages with continuous visitors, Type 2 a moving-table type only in the villages with temporary visitors and Type 3 is a fixed display-case type.

  • The purpose of this paper was to identify the effects of elimination of entrance fee (EEF) affecting visitor's satisfaction (VS) and management sectors such as natural resources (NRs), park facilities, transportation, visitor service, visitor atmosphere (VA) in national parks (NPs). This research had obtained data through a questionnaire, which surveyed 336 visitors at Gayasan NP in 2006. The data were analyzed the data using descriptive statistical methods, Pearson's correlation analysis, and multiple linear regression method. It was found that 1) About EEF, 72.6% of respondents agreed. 2) As entrance fee was abolished, respondents predicted that degree of VA such as crowding, waste throwing, disorder etc. grew worse most. On the other hands, respondents predicted number and quality of commercial lodging facilities, festival, and local products would improved. 3) Respondents predicted that degree of VS would worse. 4) in multiple regression analysis, the relative contribution of the VA on VS have been determined to have respectively 1.84 times more important than that of the change degree of NRs. The results suggested that the management of VA in NP was the most important factor to prevent decline of VS. This paper would be helpful to establish national park management policy after EEF.

  • We have investigated the distribution of major local foods cultivated in Gwangju City and Jeollanam-Do in order to understand the food culture of Honam region. The local foods were divided into 4 classes: agricultural, aquatic, animal and other products. 124 species of local foods, including 51 agricultural products, 50 aquatic products, 6 animal products and 17 others, were identified from this region. In Jeollanam-Do area, the agricultural products have a variety of fruits and vegetables, and aquatic products have fishes. In particular, rice, cucumber, pear, anchovy, oyster, laver, oyster mushroom, shiitake mushroom, and honey were determined as major local foods in Jeollanam-Do area. Note that Mudeungsan watermelon is cultivated in Gwangju, and sweet smelt and cat fish caught only in Sumjin river and Tamjin river area. In recent years, pumpkin (Cucurbita maxima Duchesne), paprika, kiwi and melon were determined as major local foods in Jeollanam-Do. Furthermore, branding strategy of agricultural and animal products can be said to improve. Wild types of aquatic productions, mushrooms and wild edible greens have been decreasing, whereas cultivated production increasing. The kinds of special local foods in Gwangju City and Jeollanamdo area were influenced by geographical, religious and social factors.

  • For the effective use of under-utilized resources, silver-stripe round herring (SSRH), the plain-dried SSRH was investigated and compared with boiled-dried SSRH and boiled-dried anchovy on the food component and sensual characterization. Moisture content and salinity of the plain-dried SSRH were 31.9% and 7.6%, respectively. Moisture content of the plain-dried SSRH was higher, while the salinity was lower than those of boiled-dried SSRH and anchovy. According to the results of peroxide value, fatty acid composition, Hunter b value, and browning index, the rancidity was higher in plain-dried SSRH than in boiled-dried SSRH and anchovy. When compared to the boiled-dried SSRH and anchovy, the plain-dried SSRH was higher in calcium and phosphorus contents, while lower in total content of amino acid. According to the results of hot-water soluble-N, trichloroacetic acid-N, free amino acid, and taste value, the taste of plain-dried SSRH was superior to those of the boiled-dried SSRH and anchovy. The results of chemical components and sensory evaluation indicated that the plained-dried SSRH could be substituted for boiled-dried anchovy classified into special grade, if fish odor of SSRH can be improved.

  • The purpose of this study was to derive selection attribute of fishing experience villages, and to analyze the importance and performance on targeting experts and experienced tourists. Consequently, it could suggest implications for the guideline and the evaluation criteria of making fishing experience villages for the revitalization of eco experience tourism. Therefore, in this study, literature investigation and IPA analysis were used by Microsoft Office Excel 2010, SPSS 20.0. As a result, the 'variety of local foods and specialties' was the most urgent attribute to require intensive management strategy. And it is recommended to improvement about 'attributes related residents' because it were insensitived on the recognition by users. Satisfaction of 'appropriateness of coast' was the lowest, but the efficiency was quite high. Finally, not only 'the area of control' but also 'the area of influence' should be reviewed as an important aspects on developing the fishing experience village. The significance of this study is to derive selection attributes of making fishing experience villages for revitalization of eco experience tourism, and to suggest strategy directions based on IPA analysis result by experts and experienced tourists. But in this study, the site was limited to Gyeonggi-do, so it is recommended to expand further.
