  • To determine dining out behaviours of fast foods at five different fast food restaurants of Youido apartment compound in Seoul, a survey was conducted of 460 customers ranging in age from 7 to 29 year, from October 1 to 5th, 1986. Findings are summarized follows: The reasons the customers the fast food restaurants by the highest percentage were the following in the order: 'the atmosphere in which fast food is eaten is enjoyable for the companionship', 'convenient to dining', 'the surroundings and dining equipment are pleasant and hygienic', and 'to be able to stay as long as I want'. The majority of the customers visited the fast food restaurants with their friends between 1pm and 5pm. The fast foods purchased by the customers were mostly for snack rather than a full meal. Preference was a major factor in food selection from available meun items. Ice cream, Kentucky fried chicken, rolled rice with laver I rice cake stew, fried Mandoo were ranged high on the list of liked foods, in contrast, lower preference was for noodle soup, small red bean porridge, pinenut porridge, and persimmon punch.

  • Seogundo is a small island adjacent to the southern coast of Jeju Island and connected to it by a boulder beach at low tide Surveys of this area were conducted from 2001 to 2009 to enumerate the mollusks there and also to examine their diversity, relative abundance, and ecological relationships. Both the boulder beach itself and several large tide pools were studied, including the coarse sand substrate and several species of seaweed and coralline algae found in the tide pools. Of the 121 species obtained or observed, there were 97 gastropods, 16 bivalves, and 8 polyplacophorans. Live specimens were obtained for about half of those species. About one third were found on rocky substrate, with the most common species being Nodilittorina radiata and Nerita japonica in the upper intertidal zone, N. radiata and Littorina brevicula in the middle intertidal, and Turbo (Lunella) coronata coreensis and Acanthopleura japonica in the lower intertidal and shallow subtidal. The seaweeds and coralline algae contained about 40% of all mollusk species. The most common mollusks in two species of brown seaweed were Ittibittum parcum, Musculus nanus, and Euplica scripta. In a species of red seaweed, Komaitrochus pulcher was the most frequent, as in the coralline algae, along with M. nanus. The coarse sand in the tidepools contained about 25% of the species, with the Cerithiidae having the largest number. A sample of beach drift contained 17 species, with Bittium aleutaceum and Rissoina (Phosinella) pura being most common. Most species, about 60%, were found in a variety of habitats, especially the marine flora; few species exhibited any habitat preferences. Biographically, Jeju Island is part of the Warm Temperate Northwest Pacific Province and the East China Sea ecoregion with a strong faunal affinity with southern Japan, eastern China, and northeastern Taiwan. Zonal-geographical groupings reveal that the fauna is mainly subtropical-low boreal, preferring moderately warm water, with a somewhat smaller number of tropical-subtropical species.

  • Distribution status and threatened assessment of endangered species, Pungitius sinensis (Pisces: Gasterosteidae), were investigated from March to October 2015 in Gangwon-do and Gyeongsangbuk-do etc., Korea. During the study period, a total of 854 individual P. sinensis were collected from 21 of 71 sampling stations using skimming nets. P. sinensis appeared in 23 streams during the past 30 years. However, it was only collected in 12 streams. Therefore, its habitats and populations were drastically reduced. The preferred habitat of P. sinensis was pool of the lower stream with lots of aquatic plants. Given these evidences of small occupying areas ($84km^2$) and drastic reduction in its habitats and populations, P. sinensis is considered as an endangered (EN) [B2ab(ii,iii,iv,v)] species based on IUCN Red List categories and criteria.

  • The distribution aspect and extinction threat evaluation of the endangered species, Cottus hangiongensis were investigated from 2011 to 2017 in Korea for this study. The distribution reports of C. hangiongensis were divided into 1954~1985, 1981~2003, 2004~2012, and 2011~2017. The number of habited streams decreased gradually to 30, 24, 10, and 19 streams, respectively. In this study (2011~2017), C. hangiongensis was newly found in two streams (Ayajincheon and Chuksancheon), but 15 streams that appeared in the past are not in this study. The main habitat of C. hangiongensis was the downstream riffle of clean water with fast velocity and cobble-boulder bottoms. Given this evidence as noted for more than a 30% reduction in population after 2003, due to construction wear, river work and the qualitative decline of the habitat, C. hangiongensis is now considered to be Vulnerable (VU A2ac) based on the IUCN Red List categories and criteria.

  • The Gold-spotted pond frog, Rana plancyi chosenica, designated as a vulnerable species by IUCN Red list. This species is a typical example facing local population threats and extinction due to human activities in South Korea. A strategic conservation plan for this endangered species is urgently needed. In order to provide information for future conservation planning, accurate information on the genetic diversity and taxonomic status is needed for the establishment of conservation units for this species. In this study, we used a molecular genetic approach using the mitochondrial cytochrome b gene and control region sequences to find the genetic diversity of gold-spotted pond frogs within South Korea. We sequenced the mitochondrial DNA cytochrome b gene and control region of 77 individuals from 11 populations in South Korea, and one from Chongqing, China. A total of 15 cytochrome b gene haplotypes and 34 control region haplotypes were identified from Korean gold-spotted pond frogs. Mean sequence diversity among Korean gold-spotted pond frogs was 0.31% (0.0-0.8%) and 0.51% (0.0-1.0%), respectively. Most Korean populations had at least one unique haplotype for each locus. The Taean, Ansan and Cheongwon populations had no haplotypes shared with other populations. There was a sequence divergence between Korean and Chinese gold-spotted pond frogs (1.3% for cyt b; 2.9% for control region). Analysis of genetic distances and phylogenetic trees based on both cytochrome b and control region sequences indicate that the Korean gold-spotted pond frog are genetically differentiated from those in China.

  • The Black-tailed gull (Larus crassirostris) is one of the most common gull species in the Northeast Asia and classified as LC (least concern) in the IUCN Red List. The bird has become a useful indicator for marine environmental pollution and habitat disruption, since the human activities impacted marine environments. Here we show that the black-tailed Gull has 6 haplotypes and some rare haplotypes are locally limited implying that the bird may not disperse far. This study may be the first report on population genetic study of Black-tailed Gull in Korea and could be used as the baseline data for monitoring and genetic study on the bird as an environmental indicator.
