We analyzed the hair microstructure of Korean small terrestrial mammals, such as Rodentia and Lagomorpha, to classify the characteristics of hair morphology. Micromys minutus showed a unicellular irregular type of medulla structures; on the other hand, the other mammals showed multicellular structures. Regarding the cuticular scale structures, the Rodentia species exhibited a narrow and broad diamond petal type, while the Lagomorpha species exhibited an elongated petal type. Interestingly, the hair cross-sections showed quite unique characteristics. We constructed hair identification keys to distinguish species with a single hair. The dichotomous key of Rodentia and Lagomorpha can be used for their behavioral ecology and dietary analysis of upper predators to serve as the basis for ecological research.

In this study, we developed 12 microsatellite markers specific to N. pygmaea using Illumina paired-end sequencing. Forty individuals of N. pygmaea collected from three currently known localities in South Korea were genotyped to validate these markers and to preliminarily assess population genetic characteristics. No locus showed significant deviation from the Hardy–Weinberg equilibrium (HWE). Our preliminary data indicate an absence of inbreeding in all populations and an absence of obvious genetic difference. The microsatellite markers developed in this study will be useful for studying the population genetics of N. pygmaea collected from other regions, including additional sites in South Korea.

쇠검은머리쑥새(Emberiza yessoensis)는 국내 및 중국, 일 본 등에서 월동하는 겨울철새로, 이들의 번식지는 국내를 제외한 러시아, 몽골, 중국, 일본의 일부지역에 분포하는 것으 로 알려져 왔다. 그러나 최근 국내 번식 사례가 최초로 관찰되 어, 이후 이들 개체군을 보전하기 위한 기초연구 필요성이 대두되었다. 쇠검은머리쑥새는 국제자연보전연맹(IUCN)에 서 준위협(NT)종으로 취급되고 있으며, 국내의 경우 멸종위 기야생생물 II급으로 지정되어있다. 이들의 국내 서식지는 현재까지 지속적으로 감소하고 있어, 월동 및 번식개체군 모두 위협받고 있는 것으로 판단된다. 그럼에도 불구하고 개체군 크기, 서식지 면적 등 이들의 정확한 국내 개체군 기초정보는 현재까지 알려지지 않아 이들의 멸종위기 위험정 도를 객관적으로 파악하는데 어려움이 있다. 우리의 연구목 적은 쇠검은머리쑥새의 국내 멸종위기 등급을 판정하는데 도움을 줄 수 있는 유전정보를 제공하는 것이다. 우리는 이를 위해 10개 이상의 microsatellite 분자표지자를 개발하고 있 다. 현재까지 29개의 분자표지자를 디자인 하였으며, 10개의 다형성을 나타내는 microsatellite 유전자좌를 관찰하였다. 이 중 4개 유전자좌의 유전다양성을 경기 안산지역에 서식중 인 32개체의 쇠검은머리쑥새 번식개체군을 대상으로 분석한 결과, 대립유전자수(A)는 2~16개, 관찰이형접합빈도(HO)와 기대이형접합빈도(HE)는 각각 0.06~0.78, 0.12~0.90의 범위 를 나타냈다. 향후 10개 이상의 microsatellite 분자표지자를 개발하여 쇠검은머리쑥새 번식개체군의 유전다양성 및 유전 구조를 파악 할 것이며, 이를 통해 개체군 기초정보가 알려져 있지 않은 국내 쇠검은머리쑥새 번식개체군 보전방안 수립을 위한 객관적인 기준을 제시할 것이다. 이 연구에서 개발한 microsatellite 분자표지자는 국내뿐만 아니라 국외에 서식중 인 쇠검은머리쑥새 개체군 보전 연구에 유용하게 활용될 것이다.

The tiny dragonfly, Nannophya pygmaea (Odonata: Libellulidae) is one the smallest dragonflies in the world and listed as a second-degree endangered wild animal in Korea. We developed microsatellite markers and applied selected markers to South Korean populations to understand population genetic characteristics, along with two mitochondrial DNA (mtDNA) gene sequences (COI and ND5). Two mtDNA-based population genetic analysis indicates substantially reduced genetic diversity in an island population (Muuido) compared to others. On the other hand, population-based FST and RST consistently support that N. pygmaea populations are overall well interconnected with a relatively high gene flow. These results may collectively indicate that N. pygmaea populations in South Korea may have rather larger population size than we previously acknowledged based on a single-locus mtDNA sequence and field observation.

Currently, only limited number of mitochondrial genomes (mitogenome) is available from Odonata. In order to extend current mitogenome data for comparative biology and phylogeny we sequenced complete mitogenomes of two endangered dragonfly species, Libellula angelina and Nannophya pygmaea (Ododana: Libellulidae). The whole genomes were 15,233 bp in L. angelina and 15,112 bp in N. pygmaea and included a typical set of genes (13 protein-coding genes, two rRNA genes, and 22 tRNA genes) and one major non-coding A+T-rich region. The arrangement of the genomes was identical to typical one found in insects. Phylogenetic reconstruction using concatenated sequences of 13 PCGs and two rRNAs of Odonata (17 species in eight families in three suborders) using both Bayesian Inference (BI) and Maximum Likelihood (ML) methods have shown a strong support for monophyletic Zygoptera (BI, BPP = 1 and ML, 100%). Currently, further scrutinized analysis is under progress.

Emotion has been discussed as a key element in the purchase decision process across several products and services by several researchers (Bagozzi, Gopinath, & Nyer, 1999; Kang, Jin, & Gavin, 2010; Lee & Park, 2013). Although a variety of products and services have been utilized to address the relationship between emotions and the purchase decision process, books, especially an online-book purchase environment, have been neglected in existing research of the relationship between emotions and the purchase decision process. Thus, the purposes of this study are 1) to investigate how book covers influence consumers’ purchase decisions in an online setting, 2) to examine the influence of two different criteria of book covers (the color of the book cover and the picture or photo on it) on consumers’ emotions of delight, and 3) to explore the cross-cultural differences (i.e., Japan vs. France) in the online book purchase decision process. Emotion is referred to “an affective, subjective, experimental, temporary, multidimensional phenomenon and a source of motivation caused by exogenous factors to the individual that interact with the process of treatment of the collected information for the purpose of experience of consumption” (Graillot, 1998, p. 12). In marketing, emotion is considered to be the beginning of the choice made by consumers (Derbaix & Pham, 1989), and many researchers have tried to find dimensions of emotion which better explain the consumer’s purchase decision process, such as circumstances (e.g., hope, relief, and joy), external cues (e.g., like, dislike, and anger), or self-created cues (e.g., regret, shame, and guilt) (Roseman, Antoniou, & Jose, 1996). In order to fill in gaps from previous research, in this study we present the following research hypotheses: H1: There will be a positive relationship between the color of the book cover and the consumer’s emotion of delight when purchasing a book from an online bookstore. H2: There will be a positive relationship between the picture or photo on the book cover and the consumer’s emotion of delight when purchasing a book from an online bookstore.H3: There will be a positive relationship between the consumer’s emotion of delight and a book’s perceived usefulness when purchasing a book from an online bookstore. H4: There will be a positive relationship between a book’s perceived usefulness and the purchase of the book. H5: The impact of the book cover on the purchase decision process will vary by country. Japan and France were chosen as the countries for the study as they are significantly similar in terms of the size of the book market on the global stage (Oricon, 2015), however the two countries are very dissimilar in terms of culture. In addition, there is no existing research that compares consumers in these two countries in an online book purchase setting. A total of 398 usable date sets were collected in Japan (n = 191) and France (n = 207) using a questionnaire survey. Two sets of questionnaires were developed in Japanese and French for the respondents and the respondents were randomly chosen for this study. All measurement items of each construct (i.e., the importance of the color of the book cover, the importance of the picture on the book cover, the emotions of delight, the perceived usefulness of the book, and the book purchase) were adopted from previous studies and measured using a 5-point Likert scale. To test the proposed research framework, in this study we developed a structural equation modeling method. Multigroup confirmatory factor analysis was conducted to test construct validity, which showed satisfactory evidence of convergent and discriminant validity. Based on Table 1, there is no significant relationship between the color of the book cover and the emotion of delight, therefore Hypothesis 1 was rejected. On the other hand, Hypotheses 2 (the relationship between the picture on the cover and the emotion of delight), Hypotheses 3 (the relationship between the emotion of delight and a book’s perceived usefulness), and Hypotheses 4 (the relationship between a book’s perceived usefulness and the book purchase) were found to be statistically significant. Finally, Hypothesis 5, indicating that the impact of the book cover on the purchase decision process varies across countries, was supported. In other words, the χ² difference test between the two countries revealed that an unconstrained model indicated a significantly better model fit than a fully constrained model (Δχ²(7) = 117.58, p < .001), indicating the evidence of differences in the path relationships between the two countries (Laukkanen et al., 2013). Since Hypothesis 5 was indicated to be significant, a further analysis of each path from Hypothesis 1 to Hypothesis 4 was conducted. This revealed that only the relationship between a book’s perceived usefulness and the book purchase was significantly different by country (Δχ²(1) = 3.91, p < .05). The study provides meaningful academic implications. This study examines the influence of the book cover on consumers’ emotions, which lead to the actual purchase of the book in an online setting and accurately explains the role of consumers’ emotions in the relationship. Furthermore, this study proved that the relationship between the book’s perceived usefulness and the purchase of the book was different by country. Given this, marketers should develop tailored marketing strategies for the two countries. For French consumers, practitioners should focus more on the usefulness of the book itself, such as the meaning of the book to readers, the impact of the book on readers, the potential for improving reader’s knowledge andhappiness, etc. In other words, marketers should emphasize and promote the concept of the usefulness of the book itself rather than the design components, such as the color of the book cover. Additionally, consumers’ emotions of delight have a significant role on the online book purchase decision, therefore promoting and arousing consumers’ positive emotions, for example, with music, easy transactions, easy access, etc., may be critical while shopping for books online.
