The red-spotted apollo butterfly, Parnassius bremeri Bremer, 1864 (Lepidoptera: Papilionidae), has been listed as an endangered species in Korea. We developed microsatellite markers by nest-generation sequencing (NGS), selected 12 markers, and applied the markers to available South Korean populations to understand population genetic characteristics. The genotyping of 40 P. bremeri individuals from three localities in South Korea showed that at each locus, the observed number of alleles ranged from 17 to 43, the observed and expected heterozygosities were 0.84722-0.90556 and 0.76045-0.79208, respectively, and FIS was –0.155 to –0.121. STRUCTURE analysis supported the presence of two genetic pools in all three populations, although an immediate reason for this subdivision is not known. The population based FST, RST, and front wing length collectively suggest that at least Samchuk population in Gangwon Province has a significant distance. Further scrutinized analysis is undergoing.

Despite of a substantial effort, the phylogeny of Lepidoptera still has unstable taxa and unresolved relationships particularly form Apoditrysia to Ditrysia (e.g. phylogenetic position and familial relationships of Gelechioidea, the monophylies of Tineoidea and Zygaenoidea and so on). We performed phylogenetic analysis using ~13,000-bp length of mitogenome sequences form 50 species (with seven species in two superfamilies form this study) representing 13 superfamilies to improve the lepidopteran phylogeny from Apoditrysia to Ditrysia. A close relationship of Gelechioidea to Obtectomera than to apoditrysian taxa was noteworthy, although the nodal support is very weak (ML, 23%; BI, BPP = 0.94). Monophyly of Zygaenoidea without Epipyropidae (Epipomponia nawai) was also noteworthy in spite of weak nodal support (ML, 64%; BI, 1.0). Scrutinized analysis is currently underway.

Dendrolimus superans (Lepidoptera: Lasiocampidae) has long been acknowledged to present in South Korea under the circumstance of a substantial change in species names of Dendrolimus. In the present study, we found that specimens of D. superans collected from South Korea were D. sibiricus, rather than D. superans. Comparison of Korean specimens to the D. superans from Japan and the D. sibiricus from Russia in terms of wing morphology, female and male genitalia, a partial COI gene sequence, and a partial internal spacer sequence 2 (ITS2) consistently supported the presence of D. sibiricus in South Korea. Phylogenetic analyses using concatenated sequences of COI and ITS2 from available individuals of D. sibiricus and D. superans both by Bayesian inference and maximum likelihood methods the Korea samples to be D. sibiricus.

Even though cars have a good effect on modern society, traffic accidents do not. There are traffic laws that define the regulations and aim to reduce accidents from happening; nevertheless, it is hard to determine all accident causes such as road and traffic conditions, and human related factors. If a traffic accident occurs, the traffic law classifies it as ‘Negligence of Safe Driving’ for cases that are not defined by specific regulations. Meanwhile, as Korea is already growing rapidly elderly population with more than 65 years, so are the number of traffic accidents caused by this group. Therefore, we studied predictive and comparative analysis of the number of traffic accidents caused by ‘Negligence of Safe Driving’ by dividing it into two groups : All-ages and Elderly. In this paper, we used empirical monthly data from 2007 to 2015 collected by TAAS (Traffic Accident Analysis System), identified the most suitable ARIMA forecasting model by using the four steps of the Box-Jenkins method : Identification, Estimation, Diagnostics, Forecasting. The results of this study indicate that ARIMA (1, 1, 0)(0, 1, 1)12 is the most suitable forecasting model in the group of All-ages; and ARIMA (0, 1, 1)(0, 1, 1)12 is the most suitable in the group of Elderly. Then, with this fitted model, we forecasted the number of traffic accidents for 2 years of both groups. There is no large fluctuation in the group of All-ages, but the group of Elderly shows a gradual increase trend. Finally, we compared two groups in terms of the forecast, suggested a countermeasure plan to reduce traffic accidents for both groups

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.

Optimizing energy usage for maximum efficiency is an essential goal for manufacturing plants in every industrial manufacturing sector. The generation and distribution of purifying compressed air is a large expense incurred in practically all manufacturing processes. Not only is the generation and treatment expensive equipment of compressed air, but frequent maintenance and effective operation is also required. As a plant’s compressed air system is often an integral part of the production process, it needs to be reliable, efficient, and easy to be maintain. In this paper, we study to find operating method to save energy from the adsorption dryer in the process of purifying compressed air, which is required for a clean room production site in “A” company. The compressed air passes through a pressure vessel with two “towers” filled with a material such as activated alumina, silica gel, molecular sieve or other desiccant material. This desiccant material attracts the water from the compressed air via adsorption. As the water clings to the desiccant, the desiccant particle becomes saturated. Therefore, Adsorption dryer is an extremely significant facility which removes the moisture in the air 70℃ below the dew point temperature while using a lot of energy. Also, the energy consumption of the adsorption dryer can be varied by various operating conditions (time, pressure, temperature, etc). Therefore, based on existing operating experiments, we have searched operating condition to maximize energy saving by changing operating conditions of the facility. However, due to a short experiment period (from September to October), further research will be focused on considering seasonality.

In mobile communication systems, location management deals with the location determination of users in a network. One of the strategies used in location management is to partition the network into location areas. Each location area consists of a group of cells. The goal of location management is to partition the network into a number of location areas such that the total paging cost and handoff (or update) cost is a minimum. Finding the optimal number of location areas and the corresponding configuration of the partitioned network is a difficult combinatorial optimization problem. This cell grouping problem is to find a compromise between the location update and paging operations such that the cost of mobile terminal location tracking is a minimum in location area wireless network. In fact, this is shown to be an NP-complete problem in an earlier study. In this paper, artificial bee colony (ABC) is developed and proposed to obtain the best/optimal group of cells for location area planning for location management system. The performance of the artificial bee colony (ABC) is better than or similar to those of other population-based algorithms with the advantage of employing fewer control parameters. The important control parameter of ABC is only ‘Limit’ which is the number of trials after which a food source is assumed to be abandoned. Simulation results for 16, 36, and 64 cell grouping problems in wireless network show that the performance of our ABC is better than those alternatives such as ant colony optimization (ACO) and particle swarm optimization (PSO).

This study investigates the influence of sintering temperature on the magnetic properties and frequency dispersion of the complex permeability of Ni–Zn–Cu ferrites used for magnetic shielding in near-field communication (NFC) systems. Sintered specimens of (Ni0.7Zn0.3)0.96Cu0.04Fe2O4 are prepared by conventional ceramic processing. The complex permeability is measured by an RF impedance analyzer in the range of 1 MHz to 1.8 GHz. The real and imaginary parts of the complex permeability depend sensitively on the sintering temperature, which is closely related to the microstructure, including grain size and pore distribution. In particular, internal pores within grains produced by rapid grain growth decrease the permeability and increase the magnetic loss at the operating frequency of NFC (13.56 MHz). At the optimized sintering temperature (1225-1250°C), the highest permeability and lowest magnetic loss can be obtained.

The Gelechioidea is the second most species-rich group of Lepidoptera, but only limited number of mitochondrial genome (mitogenome) sequences is available. Thus, we sequenced the complete mitogenome of a gelechioid Hieromantis kurokoi (Lepidoptera: Stathmopodidae) to use the data for future study for the higher phylogeny of Ditrysia in Lepidoptera. The arrangement of the genome was identical to typical one found in Ditrysia (trnM-trnI-trnQ) (underline for inverted gene). The COI began with CGA, which has been designated as the start codon for majority of lepidopteran species, whereas other protein-coding genes (PCGs) began with the typical ATN codon. The 360-bp long A+T-rich region harbored the conserved sequence blocks Phylogenetic analysis using the 13 PCGs both by Bayesian inference (BI) and Maximum-likelihood (ML) methods indicated that H. kurokoi belonging to the family Stathmopodidae grouped together with within-familial species Atrijuglans hetaohei with the highest nodal support (BI, 1.0; ML, 100%).

이 연구는 한국 중부지방 용인과 남부지방 무안에서 봄 출현 나방의 다양성 양상과 나방 종 및 개체수에 영향을 주 는 기후 요인을 알아보기 위해서 이루어졌다. 나방은 2013년 부터 2015년까지 4월 한 달 동안 일주일 간격으로 자외선등 트랩을 이용하여 채집하였다. 기후요인은 8℃를 기본으로 한 적산온도 (GDD8), 평균온도, 강우량, 일조시간, 풍속, 신적 설 등이다. 나방 종 수 및 개체수에 영향을 주는 기후요인은 단기 (채집주부터 3주전까지)와 장기 (채집 4~12주전)로 나 누어 분석하였다. 봄 출현 나방은 과 구성에서 유사한 양상 을 띠었지만 지역별로 우점한 과는 차이를 나타내었다. 자나 방과는 중부지방에서 우점한 반면 밤나방과는 남부지방에서 우점하였다. 밤나방과의 우점종은 4월 초에 나타난 반면 자 나방과의 우점종은 4월 말에 나타나 시간적인 차이도 나타 내었다. GDD8, 일조시간, 채집 일주일 전 강우량 등 3개의 단기 기후요인은 나방 종 수 및 개체수에 영향을 준 요인으 로 나타난 반면 채집 4주전 평균기온만 장기 기후요인으로 나방 종 수에 영향을 준 것으로 나타났다. 이 연구에서는 한 국에서 봄 출현 나방으로 자나방과와 밤나방과 종이 우점하 며 이들은 4월 중 우점도와 비행시기에 차이가 있는 것도 알 수 있었다. 봄 출현 나방은 따뜻함과 강우량에 영향을 받는 것으로 나타났다. 최근 기후변화는 봄 출현 나방에도 영향을 줄 수 있어 이에 대한 지속적인 감시가 필요할 것으로 생각 한다.

Butterflies are commonly used for environmental monitoring to assess biodiversity changes in the world. Occurrence of butterflies were monitored by a line transect method in Gwangneung forest for 10 years from 2005 to 2014. Totally, 8,484 individuals of 96 species of butterflies were identified. Among them, two species Libythea celtis (2807 individuals) and Pieris melete (1517 individuals) were the most abundant species, followed by Argynnis paphia (381 individuals) and Neptis philyroides (277 individuals). Meanwhile, Pieris melete and Libythea celtis showed high occurrence frequency with 84.6% (99 times among the 117 monitoring times) and 76.9% (90 times) respectively, followed by Argynnis paphia (42.7%) and Pieris canidia (40.2%). Species richness and abundance were varied at different years, and they were slightly decreasing in recent years. Most species showed annual variation in their abundance. Species abundance distribution model showed a log-normal distribution.

Saturnia (Rinaca) jonasii Butler, 1877 is distributed in Japan, including Tsushima Island and Taiwan, whereas S. boisduvalii Eversmann, 1846 is distributed in northern areas, such as China, Russia, and South Korea. In the present study we found that the specimens from Mt. Hallasan on Jejudo, a southern remote offshore island, were S. jonasii, rather than S. boisduvalii based on morphology, DNA barcode, and nuclear elongation factor 1 alpha (EF-1α) sequences. The major morphological differences between the two species included the shape of wing pattern elements of fore- and hindwings and male and female genitalia. A DNA barcode analysis of the sequences of the Jejudo specimens and S. boisduvalii, along with those of Saturnia species obtained from a public database showed a minimum sequence divergence of 4.26% (28 bp). A phylogenetic analysis also showed clustering of the Jejudo specimens with S. jonasii, separating S. boisduvalii (Bayesian posterior probability = 0.99). The EF-1α-based sequence and phylogenetic analyses of the two species from Jejudo Island and the Korean mainland showed the uniqueness of the Jejudo specimens from S. boisduvalii collected on the Korean mainland, indicating distribution of S. jonasii on Jejudo Island in South Korea, instead of S. boisduvalii.

Kentrochrysalis streckeri Staudinger, 1880 is distributed in Russia, Mongolia, China, and North Korea, whereas K. consimilis Rothschild & Jordan, 1903 has been known to occur South Korea and Japan. In the present study we found that the specimens from South Korea were K. streckeri, rather than K. consimilis based on morphology, DNA barcode, and nuclear elongation factor 1 alpha (EF-1α) sequences. The major morphological differences between K. streckeri and K. consimilis include the shape of wing pattern elements of fore- and hindwings and male and female genitalia. A DNA barcode analysis of the South Korean specimens and K. streckeri originated from Russia showed a maximum sequence divergence of only 0.659% (four bp), whereas the barcoding sequence of K. consimilis sequenced in this study and GenBank-registered sequence (JN678086), both of which originated from Japan showed the minimum sequence divergence of 2.965% (18 bp), indicating that the Korean specimens are, in fact, K. streckeri, instead of wrongly known K. consimilis. Phylogenetic analyses both by Bayesian Inference and maximum likelihood methods well supported the monophyly of South Korean specimens and Russian K. streckeri, excluding K. consimilis. The EF-1α-based sequence and phylogenetic analyses of the two species also supported the data from DNA barcode, indicating distribution of K. streckeri in South Korea, instead of K. consimilis.

The lycanid butterfly, Shijimiaeoides divina (Lepidoptera: Lycaenidae) is listed as the second-degree endangered wild animal in Korea from 2012. The 15,259-bp long complete mitochondrial genome of the species consisted of 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, with the typical arrangement found in majority of Lepidoptera. The 15,259-bp long S. divina mitogenome is well within the range found in Lycaenidae and has typical sets of 37 genes and a major non-coding A+T-rich region as 379 bp. As other lycanid butterflies S. divina COI also started with CGA. The gene arrangement of S. divina is identical to that of the Ditrysia in Lepidoptera that has the order trnM-trnI-trnQ (underline for inverted gene) between the A+T-rich region and ND2. Comparison of the skewness between the PCGs encoded in major and minor strand indicates a substantial difference between them in GC skewness (0.261 ~ 0.340 in minor strand vs. -0.081 ~ -0.115 in major strand). The 151-bp intergenic spacer sequence of the S. divina mitogenome is spread over 16 regions ranging in size from 1-53 bp. The longest one (53 bp) located between trnQ and ND2 shows substantially high sequence homology to neighboring ND2 may indicating the origination of the region by a partial duplication of the ND2 gene. One of the unusual features of the S. divina mitogenome is the presence of a trnK-like sequence that is encoded at the major strand of the genome in the A+T-rich region.

The advancement of industry and science in modern society has facilitated the inherent growth of humanity due to the provisions of large amounts of information and knowledge. Deconstructionism originated from the desire for self-expression rooted in the inherent growth of humanity and desires to express various characteristics through deconstruction and not be classified and constrained by existing dichotomous structures and forms. Deconstructism (an idea to resist dichotomous ideas and existing structuralism) seeks androgyny as well as the deconstruction of sex vis-à-vis human desire. Human androgyny, inherent in history and ancient Greek myths (Kwon, 2002), is now being adapted by modern society, psychology, culture, and art (Han & Kim, 2012). Androgyny, adapted by literature, sculpture, and painting, is now being used by the production of various images as well as modern fashion costumes. It is necessary to study androgyny to provide an aesthetic value for modern fashion design that can also deeply analyze the ideas and philosophies of fashion designers. This study considers androgyny with a focus on deconstructive fashion, understanding the tendency of androgyny in modern fashion, and providing a reference material for future fashion designs as well as for the direction and development of various fashion accessories and hair accessories. This study uses internet resources and previous research from professional journals and books about deconstructionism and androgyny for a literature review. It adapts an empirical method based on visual images from the design collections of designers defined as deconstructive fashion designers by researchers and professional editors. The androgyny of deconstructive fashion is classified in this study as follows. The first are ambiguous designs that show no clear distinction between sexes. The designers show designs unconstrained by sexes and which seek human instinct through wearing fashion items of the opposite sex that use masks and express sexual ambiguity with makeup and costumes. The second is integration shown in designs with both masculine and feminine characteristics. The designers integrates the lines and details of the opposite sex with costumes and patterns to escape existing ideas and show a silhouette that eliminate sexual stereotypes. The third is deconstructivity as shown in designs with no sexual characteristic and no sexual concept. It is a trend that originated from the interpretative view that adapts the super realism of deconstructionism and is free from an existing aesthetic consciousness to deconstruct a sex role for existing costumes and refuse all standardized ideas; consequently, the roles of costumes and items are eliminated and a new fashion style emerges from the individual values and ideas of designers. The androgyny of modern fashion from deconstructionism diverges from traditional form, integrates with aesthetic factors, and becomes one of a modern style that also provides more creative design motifs for fashion designers.

본 연구는 전 세계적으로 심화되고 있는 갯녹음의 발생 현황과 아열대 및 열대해역에서 우점하는 산호류의 심각한 산호백화 현상의 분포 정도를 파악하였다. 갯녹음이 발생하는 원인은 물리적, 화학적 및 생물학적 원인으로 나눌 수 있으며, 매우 다양한 원인에 의해 갯녹음이 발생하는 것으로 나타났다. 국내에서 발생한 갯녹음은 점점 증가하고 있으며,실제 진행 중인 면적은 이보다 훨씬 많을 것으로 예상된다. 또한 산호백화 현상은 전 세계 연안에 걸쳐 발생하고 고 있으며..

The species status of Oeneis urda (Eversmann) and O. mongolica (Oberthür) has been argued based on morphological characters. Reexamination of their major morphological characters has shown a slight differentiation in the two species. Sequences of three mitochondrial genes (COI, ND6, and ND1) and one nuclear region (internal transcribed spacer 2, ITS2) from two O. urda populations (Yangyang and Mt. Hanla) and one O. mongolica population (Uljin) were performed for phylogenetic and population genetic inferences. Sharing of identical sequences in the ND6 gene and ITS2, minimal sequence divergence in the COI and ND1 genes, and phylogenetically undividable sequence types in all mitochondrial genes and ITS2 suggest genetic continuity between the two species. Nevertheless, significant FST estimates (p < 0.05) were found for the COI gene in comparisons between Yangyang (O. urda) and Uljin (O. mongolica), between Yangyang (O. urda) and Mt. Hanla (O. urda), and between Uljin (O. mongolica) and Mt. Hanla (O. urda) populations. These FST estimates, along with other gene-based analyses collectively suggest isolation of the two species at some point in the past, but incomplete separation between the two species on the mainland (Yangyang and Uljin) and biogeographically forced isolation of the O. urda population on Mt. Hanla collectively appear to complicate species status of these two species that were once further clearly separated.
