본 연구를 통해 한국에서 자생하는 털날개나방 중 가장 큰 종, Platyptilia nemoralis zeller가 새롭게 추가되었다. 그 성충의 외부 형질과 생식기 형질 특징이 기주식물과 분포 정보와 함께 제공되었다.

인접 국가인 일본의 후쿠시마 원전에서 극한 자연재해로 인한 중대사고가 발생하면서, 국내에서 중대사고 및 확률론적 안전성 평가 (PSA, Probabilistic Safety Assessment)에 대한 중요성이 재인식되었다. 국내에서는 원전의 소외결말을 평가하는 3단계 PSA에 대한 연구개발이 최근까지 거의 이루어지지 않았다. 본 논문에서는 국외 3단계 PSA 전산코드 중, 미국의 MACCS2 (MELCORE Accident Consequence Code System 2), 유럽의 COSYMA (COde SYstem from Maria) 그리고 일본의 OSCAAR (Off-Site Consequence Analysis code for Atmospheric Releases in reactor accidents)에 대한 간략한 분석과 미국 의 MACCS2에 대한 단점 및 한계점 분석을 수행하였다. 국내·외 전문가들에 의해 공통적으로 지적되어 온 MACCS2의 한 계점은 다수호기사고와 사용후핵연료 저장조로부터의 방출 모사의 불가능, 그리고 대기확산모델을 단순 가우시안 플륨모델을 기본으로 한다는 것이며, 이중 일부는 MACCS2업데이트 버전을 통해 개선되어 왔다. Food chain 모델의 모사의 제한, 해양 및 수계 확산모델의 부재, 제한된 범위의 경제영향평가 등 또한 개선되어야 할 사항이다. 기술보고의 결과는 국내 3단 계 PSA 관련 기술 개발을 위한 기초자료로 활용될 수 있을 것으로 기대된다.

동해 남서해역 퇴적물의 현장 음파전달속도를 파악하기 위하여 신호투과법을 이용하여 퇴적물의 실험실 음파전 달속도를 측정하였다. 측정된 실험실 음파전달속도는 해저면 온도, 해수 음파전달속도, Kim et al. (2004)과 Hamilton (1980) 모델을 적용하여 현장 음파전달속도로 보정하였다. Kim et al. (2004)과 Hamilton (1980)의 현장 음파전달속도는 연구지역 퇴적물 특성을 반영하며, 유사한 분포를 보인다. 현장 음파전달속도 보정에는 해저면 온도의 영향을 크게 받 는 것을 확인할 수 있다. 따라서 퇴적물의 실험실 음파전달속도를 통해 현장 음파전달속도를 파악하기 위해서는 해저 표층 온도 자료를 통한 온도 보정이 반드시 수행되어야 한다.

본 연구에서는 항 내부에서 부하되는 오염물질이 파랑 및 흐름 조건으로 인하여 항외로 유출되는 과정을 수리실험을 통해 알아보았다. 월성원자력발전소 항내에 오염물질이 부하 되었을 시, 실험인자를 변화시켜가며 추적자를 활용한 흐름거동 조 사를 수행하였다. 각 실험의 결과는 지수 함수에 따른 항내 오염물이 감소하는 경향이 나타나며, 항외 유출에 걸리는 시간의 기울기는 각각 다른 결과를 보여주었다. 관측된 데이터로부터 회귀식을 도출한 결과, 흐름 관측의 경우 유입되는 모터의 회 전 속도 30, 20, 10 rpm에서 좌측 항내의 오염물이 50% 유출률에 도달하는 시간은 각각 2.70, 10.40, 26.39 days를 보였다. 모터의 회전속도가 30 rpm인 실험에서 유출되는 감소 추세가 가장 뚜렷하게 나타났으며, 회전속도 10 rpm인 실험에서 기 울기는 완만하였다. 파랑 관측의 우측 영역의 오염물이 50% 유출률에 도달하는 시간은 4.59 days로 나타났으며, 좌측영역 의 경우 15.35 days의 결과를 보였다.

Subfamily Cryptolechiinae Meyrick 1883 (Depressariidae sensu Heikkila et al., 2014) is reviewed from Korea. The Cryptolechiinae comprising nearly two hundred species worldwide (Wang, 2006), is characterized by forewing broadly lanceolate, the male genitalia without gnathos and female genitalia with well-developed lamella antevaginalis. In the Korea fauna, only four species of two allied genera, Acryptolechia and Cryptolechia, were recognized with two new species. A full bibliography, diagnosis and descriptions for all known species including new species are provided with illustration. Keys to species are also given.

The mitochondrial COI gene has proven successful for identifying the lepidopteran species. In addition, this gene has been applied to recognize cryptic species and confirm a polyphagous species as one species. However, it has been also reported misidentification in the COI gene. As a result, some researchers have suggested the use of additional genes in species identification, especially, nuclear genes. In this study, we observed that a nuclear EF1agene is better than the mitochondrial COI gene in recognizing Stathmopoda species. For example, among the all species, 47 individuals of nine species, a large intraspecific pairwise difference were detected, up to 15.0% in universal barcoding regions of the COI gene, 22.0% in other part of the COI gene; however, 2.0% in EF1a. In contrast, Stathmopoda sp2 and S. commoda were separated into several clusters in each different COI regions, and some individuals of S. auriferella and S. commoda, were closer to each other separating from the cluster of the same species. But, we get clear results from the EF1a, Stathmopoda species well clustered and could be distinguished.

Laos, a landlocked country in Southeast Asia, has most extensive network of ecosystems in the Indochina Peninsula, surrounded by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the south and Thailand to the west. It is the tropical vegetation and warm climatic conditions influenced by monsoon. Such geographical and climatic condition is favorable for the diversity of insects. However, research or educative investigation on insects have been poorly conducted. Through recent expedition during dry season (between December 2012 and February 2013), mainly held at Phou Khao Khouay National Park (PKKNP), which varies from sheer sandstone cliffs and pristine river gorges to rough mountain slopes along the Mekong river, we recognized atotal of 88 lepidopteran insects belonging to 22 families, Arctidae, Attevidae, Choreutidae, Cossidae, Crambidae, Geometridae, Gracillariidae, Hesperidae, Hyblaeidae, Limacodidae, Lycaenidae, Lymantridae, Noctuidae, Nymphalidae, Oecophoridae, Papilionidae, Pieridae, Pyralidae, Scythrididae, Sphingidae, Uraniidae and Zygaenidae, were recognized.

Oecophoridae (Lepidoptera: Gelechioidea), the concealer moths, is worldwide in distribution and comprises more than 4,000 described, particularly in Australia with over 3,000 endemic species. To date, the phylogenetic relationships of Oecophoridae have been poorly known, except a few works on the higher-level phylogeny of the superfamily Gelechioidea which includes some species of Oecophoridae. This study is the first comprehensive molecular phylogenetic analysis of Oecophoridae, based on 4,395 base pairs of mitochondrial protein coding gene (COI), nuclear ribosomal RNA genes (18S and 28S) and nuclear protein coding genes (IDH, MDH, Rps5, EF1a and wingless) for 82 taxa. Data were analysed using maximum likelihood (ML), maximum parsimony (MP) and Bayesian inference (BI) phylogenetic frameworks. The results are shown that the family Oecophoridae is not monophyletic, as the genus Casmara is closely clustered with Stathmopodidae far from the Oecophorid lineage and the genera Tyrolimnas and Phaeosaces are closely clustered with Depressariinae in the Elachistid lineage. Main clade of Oecophoridae comprises Xyloryctinae previously assigned to Xyloryctidae, closely claded with New Zealandian Oecophorids including the genera Hierodoris, Gymnobatra and Izatha; the problematic position group, Acryptolechia spp., Deuterogoniinae and Oecophorinae.

The family Pterophoridae (Lepidoptera), plume moths, consist of 1,136 species listed in the ‘world catalogue’ by Gielis (2003), and a few more described since then. Approximately 250 species are known in the Palaearctic Regions (Arenberger, 1995). In this study, 35 species of 21 genera have been reviewed from Korea (Matsumura 1931, 1938; Zoological Society of Korea 1968; Park 1983; Arenberger 1991; Kim et al., 2010a, 2010b, 2012a, 2012b). We suggest the problematic species, Platyptilia ignifera, is morphologically and genetically separated from congeneric species supporting the possibility as a new genus, and employ the classification system of Arenberger (1995) rather than that of Gielis (1993) using parsimony based on morphological characters.

Until now, seven species, Acosmeryx nega, Herpetogramma luctuosalis, Ostrinia furnacalis, Endoclyta excrescens, Spodoptera litura, Paranthrene regalis, and Nippoptilia vitis, have been known as lepidopteran grape pests in Korea (Woo, 1980; Lee, 1981; Kim, 1991; NIAST, 2002; Korea grape community, 2009). We discovered thirteen additional species belonging to eight families from Gwangwon and Chungbuk provinces, Korea. Additionally, we corrected the previous records of Deuterocopus albipunctatus and Nppoptilia vitis. They were identified by adult external or genitalic characters first, and also confirmed by the COI marker, compared with two public databases, NCBI and BOLD.

The tribe Oxyptilini Bigot et al. 1998 (Lepidoptera: Pterophoridae) consists of fifteen genera with more than 100 species worldwide. Almost half of them are mainly distributed in Palaeartic Region, others are in Afrotropical, Oriental, and Nearctic regions, and less than 10 species are in Australiasian, Neotropical, and Pacific regions (Gielis 2003). Nevertheless, it has been poorly known in the Asian part of Palaeartic region, with five species in Japan (Yano 1963), two species in Russia (Sinev 2008), and one species in China (Li et al. 2003). In Korea, only one species, Stenodacma pyrrhodes (Meyrick 1889), has been reported from North Korea (Arenberger 1991). During this study, four genera (Capperia Tutt, Oxyptilus Zeller, Procapperia Adamczewski, and Tomotilus Yano), are recognized for the first time from Korea, and a new generic combination of Tomotilus celebrates (Merick 1932), comb. nov., is proposed.

Systematic studies within the family Pterophoridae have been determined by external morpholgical characteristics (Yano 1963, Spuler 1910, Meyrick 1910). However, it is sometimes to be the result of species misplacement by the variation, depending on geographic isolation and genetic drift (Moran, 1986; Shufran et al., 2000; Anstead et al., 2002; Margaritopoulos et al., 2006). The genus Platyptilia Hübner [1925] is one of the largest genera of the family comprising more than 100 species according to the World’s Catalog by Gielis (2003) mainly distributed from Palaearctic and Afrotropical regions. Within the genus, Platyptilia ignifera has been suspected as very differentiated from other congeneric species in the morphological characters. In this study, to ascertain a placement of the species, we performed molecular analysis with one mitochondrial gene, COI and one nuclear gene, 28S, and morphometric analysis based on six ratios characters using principal components analysis (PCA). The sequences of the two genes, COI, 28S, implied that Platyptilia ignifera separated from Platyptilia spp. In addition, P. ignifera exhibited morphological characteristics distinct from other congeneric species. Based on these results, we propose that Neoplatyptilia gen. nov., for Platyptilia ignifera.

The genus Promalctis Meyrick, 1908 is the largest genus of the family Oecophoridae, with more than 150 described species in the world (Wang et al., 2009; Du et al., 2009). The genus is mainly distributed in the Palaearctic and Oriental regions, probably with the highest diversity in the South and East Asia. However it has been very poorly studied to date, with only with only 4 publications which were based on very limited collecting. In total, 76 were reported from China, which is more than half of the known species in the Palaearctic region(Wang, 2006; Du et al., 2009), 14 species known from Korea (Park & Park, 1998), 12 species from Japan (Fujusawa, 2002), 8 species from Russian Far East (Lvovsky, 1976, 1985, 1986), and 3 species from Nepal (Lvovsky, 2000a). In the Oriental region, since Meyrick (1908a, 1908b) described 14 species from India and Myanmar, Lvovsky (2000a, 2000b) described 25 additional species from the southern Asia, including the southern part of China, Malaysia, Indonesia, and the Philippines. In Vietnam, only 4 species, Promalactis albiapicalis Lvovsky 1997, P. buonluoi Lvovsky 1997, P. fansipanella Lvovsky 2007, and P. suzukiella (Matsumura 1931), have been described to date(Lvovsky, 1997, 2007a). The aim of this study is to describe six new species of Promalactis based on material mainly collected in the northern part of Vietnam. Adults, head parts, wing venations, and the male or female genitalia of the new species are illustrated.

Metcalfa pruinosa (Say) (Hemiptera: Flatidae), the citrus flatid planthopper(CFP) is suddenly discovered this year in Seoul and Gyeonggi Province, Korea. CFP is originally distributed in the Eastern parts of North America(Metcalf and Bruner 1948), and recently spreading to European countries(Baker et al. 2008) such as northern Italy, Spain, and France. It is an economically important plant-sucking insect having wide host range including many agricultural crops such as grapefruit and citrus, and ornamental trees, camellias, azaleas, and magnolias(Dean and Bailey 1961) mediating plant viruses. We discovered large samples on Hosta longipes (Franch. & Sav.) Matsumura, Liriope platyphylla F.T.Wang & T.Tang, Weigela subsessilis L.H.Bailey, etc. in Seoul and Suwon on August 2009. In this report, we announce their taxonomic position, morphological characters, distribution, host information, and importance as a possible pest in the Korean peninsula.

We reviewed the tribe Oidaematophorini from the Korean peninsula. Fourteen species of 5 genera are recognized including new species, Hellinsia chuncheonensis sp. nov. and H. cyrtoacantha sp. nov. Five species are also reported as new to Korea: Adaina microdactyla (Hübner [1813]), Hellinsia ishiyamanus (Matsumura 1931), H. kuwayamai (Matsumura 1931), H. nigridactyla (Yano 1961) and Oidaematophorus iwatensis (Matsumura 1931). All the available information, including distributional ranges and biology of each taxon, is provided. The keys to the genera and species of Oidaematophotini is given. Illustrations of the images and male and female genitalia are provided.

The genus Platyptilia Hübner is the largest group of the tribe Platyptiliini (Lepidoptera, Pterophoridae) distributed in the Afrotropical and Palaearctic regions and rarely from the Pacific and Nearctic region, with 107 species (Gielis 2003) known from all over the world. From the Palaearctic region, 25 species have been described: 6 from Japan, 3 from China, and 11 from Russia, and two species, Platyptilia suigensis Matsumura and P. farfarellus Zeller from Korea. Recently, we recognized 5 species, including a new species and two species new to korea: Platyptilia ignifera Meyrick and P. nemoralis Zeller.

Park (2001) described a new species of Tisis Walker, which was the first lecithocerid recognized from Thailand. Subsequently, several taxonomic papers on the family in Thailand have been published, in which more than 50 new taxa were described (Park, 2002a-b; 2003a-c; 2004; 2005a-b; 2006a-b). For the genus Torodora Meyrick, Park (2002a, 2007) described 18 new species from Thailand. Recent study of the lecithocerid moths collected in Thailand during 1980 revealed two species with venation that does not match that of any of the known genera of the family. The two species look more or less similar each other in the forewing coloration, but the shape of the wings and their venation are quite different. Generally, for the genus-level taxonomy in the family Lecithoceridae, the wing venation has been treated as most important character distinguished genera, and many genera of the family, more than 40% of the known genera, were established as monotypic by early workers (Meyrick, 1925; Gozmäny, 1978), based on their different venations. Although the wing venation is an important character to define the generic status of the family, the combination of venations with the other morphological characters including genital character should be considered. For these reasons, many small genera of the family are needed to be revised with a result in comparison of more characters other than wing venation. In this study, two new genera, Caveana gen. nov. and Triviola gen. nov., belonging to the subfamily Torodorinae, based on Caveana diemseoki sp. nov. and Triviola puiensis sp. nov. are described. At the same time, two new Torodora species, T. karismata sp. nov. and T. youwon sp. nov., are also described from Thailand. Images of adults and genitalia are given. Specimens examined are based on the collection of the Osaka Prefecture University, collected in Thailand by Japanese specialists during 1980
