국내 늦반딧불이(Pyrocoelia rufa)이 미토콘드리아 DNA중 COI 유전자 일부(403 bp)의 염기서열을 결정, 집단내 유전적 다양도, 지역적 변이, 계통유전적 관련에 대한 분석을 실시하였다. 남해, 부산, 무주, 용인 등 우리나라 4개 지역으로부터 채집된 총 26개체로부터 7개의 mtDNA haplotype을 얻었으며 이들의 변이는 0.2~1.2%이었다. 도심인 부산에서 채집한 늦반딧불이는 다른 산림 및 농업의 채집지역과 달리 하나의 haplotype으로 고정되어 있어 도시화에 따른 집단의 병목현상과 서식처 파편화가 심각했음을 보여주었다. 그러나 우리나라 최대의 반딧불이 서식처이자 보호지역으로 지정된 무주로부터 4개의 haplotype을 얻었으며 이들의 최대염기 치환율은 1.0%로 가장 높은 집단내 유전적 다양도를 나타내었다. 근해의 섬인 남해의 늦반딧불이는 상대적으로 낮은 haplotype 다양도(H=0.25)와 계통유전적으로 이질적인 haplotype(PR7)의 존재로 요약되었는데 이는 비교적 가까운 과거의 한반도 생물지리 역사 및 유전자 이동에 의해 나타난 현상으로 설명하였다. 계층적 유전분석 결과 무주-용인과 부산-남해 그룹의 형성은 역사적으로 두 그룹사이에 유전자 이동에 반한 장벽의 존재 가능성을 제시한다고 설명하였다.

A swarm robot system consists of with multiple mobile robots, each of which is called an agent. Each agent interacts with others and cooperates for a given task and a given environment. For the swarm robotic system, the loss of the entire work capability by malfunction or damage to a single robot is relatively small and replacement and repair of the robot is less costly. So, it is suitable to perform more complex tasks. The essential component for a swarm robotic system is an inter-robot collaboration strategy for teamwork. Recently, the swarm intelligence theory is applied to robotic system domain as a new framework of collective robotic system design. In this paper, FA (Firefly Algorithm) which is based on firefly's reaction to the lights of other fireflies and their social behavior is employed to optimize the group behavior of multiple robots. The main application of the firefly algorithm is performed on path planning of swarm mobile robots and its effectiveness is verified by simulations under various conditions.

Fireflies, the luminescent insect, have species specific flash patterns, being recognized as sexual communication. The lucifrrase gene is sole enzyme responsible for bioluminescence. The firefly luciferase gene is widely used as a genetic marker or as a reporter gene in a variety of organism including bacteria, plants and animals. In this study, we illustrate the complete organization of the genomic structure of the luciferase gene from L. lateralis sampled in Boun and Muju, Korea. (omitted)

1/f fluctuation characteristics can be seen in various natural phenomena, such as breezes, streams, candle flames and the luminous patterns of fireflies. It is said that the 1/f fluctuation are comfortable for human beings. And they are introduced into many industrial products, such as an air conditioner, music, lighting, etc. This study focused on verifying the effects of 1/f fluctuation sound on comfort sensibility. Stimulus were divided into three groups(Group 1, 2, 3) by sound generation methodology. Fluctuation patterns of group 1, 2 were given by three types of fluctuation, 1/f0, 1/f1, 1/f2, and its of group 3 were given by two types of pure tone, 1/f1. In order to verify the effects, we measured the physiological responses of the subjects such as EEG(Electroencephalogram), ERP(Event-Related Potential), and these physiological responses were compared with subjective assessments, free answers. Consequently, we found that factor which had an effect on comfort sensibility was cognitive factor(for stimulus) rather than 1/f fluctuation sound pattern.

This study makes an attempt to appraise how much successful both (Ham-Pyung) Butterfly Festival and (Mu-Ju) Firefly Festival are in the view point of ecology-friendly effects, and based on this appraisal, searches for desirable and developmental directions of other eco-festivals. The empirical analysis of the study shows that even if the Butterfly Festival turns out to be more famous than the Firefly Festival, the latter is confirmed to be more eco-friendly than the former. The fact that the latter is more eco-friendly seems to be due to the fact that the subject matter, that is the theme, of the festival is the fireflies which are not only natural monuments but also peculiar in-site-resources specific to Mu-Ju. This fact suggests that the other eco-festivals, newly emerging ones in particular, need to find and designate in-site-resources inherent in their regions as the theme, as far as possible.

We describe here the complete nucleotide sequence and the exon-intron structure of the luciferase gene of the firefly, Pyrocoelia rufa. The luciferase gene of the P. rufa firefly consisted of six introns and seven exons coding for 548 amino acid residues. From the translational start site to the end of last exon, however, the genomic DNA length of the P. rufa luciferase gene from the Korean and Chinese samples spans 1,968 bp and 1983 bp, respectively, and 3 amino acid residues were different to each other. Additionally, we also analyzed mitochondrial cytochrome oxidase I(COI) gene of the Chinese P. rufa fireflies. Analysis of DNA sequences from the mitochondrial COI protein-coding gene revealed 4 mitochondrial DNA sequence-based haplotypes with a maximum divergence of 0.7％. With the 20 P. rufa haplotypes found in Korea, phylogenetic analyses using PAUP and PHYLIP subdivided the P. rufa into three clades, termed clades A and B for the Korean sample, and clade C for the Chinese sample.

This study aims to present primary data for habitat restoration and artificial breeding conditions of L. unmunsana by identifying the habitat conditions and the larvae's food sources. In order to investigate the habitat characteristics of the adult L. unmunsana and land snails, which are the primary food sources for the larvae, field surveys were conducted on a total of 10 habitats in south-central parts of Korea including Sanseongcheon, Jeonju. The results revealed that the L. unmunsana habitat in the Sanseongcheon area had a broadleaf forest with a multi-layered vegetation structure, adjacent water features, and the north/northeast/northwest slopes with little effect of artificial lighting. The adult L. unmunsana in the Sanseongcheon area appeared from the end of May to the end of June, and was especially intensively observed around the middle of June. The most active time was from 23:30 to 00:30 with a temperature range of 19~22℃ and higher than 80% humidity. The peak count of the observed adults L. unmunsana was a total of 774 on June 11, 2021. In the case of land snails, 11 families and 23 species were observed in 10 habitats of L. unmunsana, and Euphaedusa fusaniana was the most extensive and the most observed in the five survey areas. The land snails of L. unmunsana habitats are mostly found under the organic layers of leaves and a fallen tree branch in broadleaf forests, where a thick organic material layer buffers temperature changes and provides high humidity for various snails. These habitat conditions are suitable for the larva of L. unmunsana and land snails to inhabit, feed, hide and hibernate.

본 연구는 영양군에서 개최되는 반딧불이 축제를 사례로 지역축제 이미지가 관광객의 만족과 재방문의사에 미치는 영향에 대해 분석을 하였다. 영양반딧불이 축제는 현재 5회가 개최되었고 다른 지역의 축제와는 다르게 주간과 야간에 이루어지는 축제로 영양지역의 자연환경과 생태환경을 부각시키고 다른 지역 축제에서 볼 수 없는 살아있는 곤충은 가지고 진행한다는 특이한 점이있다. 야간 반딧불이 날리기 체험, 곤충 만들기 등 축제에 참여하는 관광객이 기대했던 다양한 볼거리와 체험행사로 구성되있다. 본 연구에서는 지역축제이미지가 관광객의 만족과 재방문의사에 미치는 영향에 관한 연구로 지역축제이미지에 대해 20개의 항목을 구성하여 축제에 참여하는 관광객의 다양한 요인을 분석하였고, 지역축제이미지에서 나타난 다양한 요인이 관광객의 만족으로 이루어지는 다양성, 체험, 편리성, 축제내용의 전달과 창의성에 대해 분석을 하였다. 본 연구에서 분석한 결과를 보면 지역축제 이미지와 만족이 축제를 체험하는 관광객에게 재방문의사를 밝히는 계기가 되었다는 점이다. 지역축제 이미지와 관광객만족, 재방문 의사는 축제를 진행하는 프로그램의 다양성과 새로운 체험, 기대심리, 다양한 정보 전달이 중요하고 축제 내용에 맞게 친환경적이고 생태환경적인 다양한 프로그램이 개발되어야 하고 일시적이 아닌 꾸준한 친환경적 축제로 발전되어져야 할 것이다.
