Plant bugs of the subfamily Phylinae from Laos (Hemiptera: Heteroptera: Miridae)
Ram Keshari Duwal,Tomohide Yasunaga,이승환 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.1
The phyline plant bugs in Laos are reviewed on the basis ofmore than 300 specimens collected in a series of field investigations by Seoul National University, Korea. Twenty-six species belonging to the subfamily Phylinae are recognized and four species are described as new to science. A new genus, Indochinapsallus Duwal, Yasunaga & Lee n. gen. is proposed to accommodate one of the new species. Accordingly, the following new taxa are diagnosed, described and discussed herein: Acrorrhinium laos Duwal, Yasunaga & Lee, Europiella indochinana Duwal, Yasunaga & Lee, Indochinapsallus rufobrevis Duwal, Yasunaga & Lee, and Leucodellus laosensis Duwal, Yasunaga & Lee. An annotated checklist of all currently known Lao phyline taxa, including new distributional records for four genera and five species is provided.

The mirine plant bug genus Paramiridius, which has been known only by a single Taiwanese species, is reported from Indochinese Laos for the first time and redefined. Two additional species, P. indochinensis and P. laomontanus, are described as new to science. The female genitalic structures are from the first time figured for the genus. A key is provided for all three known Paramiridius species.
Taxonomic Notes on the Genus Philostephanus Distant (Heteroptera: Miridae: Mirinae) from Korea
Jongwoon Seong,Gwan-Seok Lee,T. Yasunaga,Seunghwan Lee 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.05
The genus Philostephanus Distant 1909 belongs to the family Miridae, including 23 species from the eastern Palearctic and the Oriental regions. They are characterized with a relatively large body, brown or fuscous coloration, rather symmetrical parameres of male genitalia, and unique structures of female genitalia. Especially, the respective structures of female genitalia exhibit distinct interspecific variation, which is uncommon in other genera of Miridae, so they are used as key characters in identification and phylogenetic study. Most of members are known to inhabit deciduous trees, and their feeding habits are considered predominantly predaceous although some species are known to use some deciduous trees as their breeding hosts (Yasunaga & Schwartz, 2007). Presently, two species are reported in the Korean fauna (Kwon et al., 2001). During our study, we found one newly recorded Philostephanus species from Korea, P. ulmi (Kerzhner 1979), which is distinguished from other Korean congeners by speckled hemelytra with pale portions. In this study, we provide taxonomic information on P. ulmi and review briefly the Korean Philostephanus species with morphological keys and photos of specimens.
Review of Plant Bug Tribe Pilophorini from Nepal (Heteroptera: Miridae: Phylinae)
Ram keshari DUWAL,Seunghwan LEE,Tomohide YASUNAGA 한국응용곤충학회 2008 한국응용곤충학회 학술대회논문집 Vol.2008 No.05
Four species in two genera of the tribe Pilophorini, the ant mimetic Plant bugs are revised from Nepal. One new species of genus Pilophorus Hann, P. sp. nov is proposed. Pilophorus typicus (Distant, 1909) and Sthenaridea piceonigra (Motschulsky, 1863) are new record to Nepal. Pilophours josifovianus Duwal and Yasunaga, 2008 previously described species from Nepal and all other three species are here with illustrations of male and female genitalia and their biological information.
A Class of Multiuser Interference Free Modulations Produced by General Orthogonal Modulations
Yasunaga, Takashi,Oka, Ikuo,Ata, Shingo,Fujiwara, Chikato 통신위성우주산업연구회 2004 Joint Conference on Satellite Communications Vol.2004 No.-
Suppression of multiuser interference effects in a frequency-selective fading channel is big issue in mobile communication system. In this paper, a parameter of modulations is discussed to develop new modulations which do not yield multiuser interference in CDMA. The modulations are shown to be in a certain class of general orthogonal modulations. The general orthogonal modulations are based on orthogonal vectors, which are obtained by multidimensional rotations and have parameters of rotation planes and rotation angles. We find the parameters of general orthogonal modulations that preserves orthogonality among users in the frequency-selective channel. The derived parameters express the new modulations, whose transfer matrices are expressed by a Kronecker product of two rotation matrices. We obtain the parameters that maximize constellation distance by computer simulations. Numerical results of distance are demonstrated to compare the performance of widely used CDMA and the new modulations proposed in this paper.

The fauna of the nasocorine plant bug genus Campylomma Reuter from the Oriental Region, including subtropical Japanese Ryukyu Islands (Okinawa Island of Southwest Islands-group) and Taiwan is updated. Three new species are herein described, C. astica n. sp. (from Okinawa and Taoyuan, Taiwan), C. hibiscicola n. sp. (Bangkok, Thailand) and C. nanrenana n. sp. (Pingtung, Taiwan). Of these, C. astica and C. hibiscicola, were observed to have cryptic habitat-preference, inhabiting bracts, stipules or flower buds of the sea (or coastal) hibiscus, Hibiscus tiliaceus (L.) (Malvaceae), planted for landscaping at urbanized zones. An updated checklist of the 22 Oriental Campylomma species is provided.
Yasunaga, Tomohide,Oh, Minsuk,Lee, Seunghwan Pensoft Publishers 2016 ZooKeys Vol.603 No.-
<P>Abstract</P><P>A new species of the plant bug tribe Mirini representing a new genus, <I>Fangumellusflavobadius</I>, is described from Laos. This genus is characterized primarily by the medium-sized, ovoid, tumid body, less shiny, roughened, almost impunctate dorsal surface, short antenna and labium, short pygophore, and atypical shape of parameres and endosoma. The phylogenetic relationship to other known mirine genera is also discussed.</P>
Rotational Acetabular Osteotomy
Yuji Yasunaga,Jiro Fujii,Ryuji Tanaka,Shinji Yasuhara,Takuma Yamasaki,Nobuo Adachi,Mitsuo Ochi 대한정형외과학회 2017 Clinics in Orthopedic Surgery Vol.9 No.2
Hip dysplasia is the most common cause of secondary osteoarthritis (OA). To prevent the early onset of secondary OA, Nishio’s transposition osteotomy, Steel’s triple osteotomy, Eppright’s dial osteotomy, Wagner’s spherical acetabular osteotomy, Tagawa’s rotational acetabular osteotomy (RAO), and Ganz’ periacetabular osteotomy (PAO) have been proposed. PAO and RAO are now commonly used in surgical treatment of symptomatic acetabular dysplasia in Europe, North America, and Asia. The aim of this paper is to present the followings: the patient selection criteria for RAO; the surgical technique of RAO; the long-term outcome of RAO; and the future perspectives.

The nasocorine plant bug genus Campylomma Reuter from Indochina is reviewed. Nine species are currently recognized, including a new species very recently discovered from Krabi and Phang Nga, S. Thailand, C. seunghwani, which is described and figured, with discussion on its peculiar habitat preference on Macaranga tree. A key to all species reported from Indochina is provided; this key now enables workers to unequivocally distinguish both sexes of several taxonomically confused members.An annotated checklist including host and distribution records is also presented.
