Subgenus Bothynoptera Schaum, 1863 of the genus Parena is mainly found in Oriental region. Despite this widespread distribution, species of the subgenus Bothynoptera are poorly known in Korea. While a total of 14 species have been recorded worldwide, only 3 species have been recorded in Korea. In this study, as a revisional work of Korean known species, a pictorial key and photographs of habitus and male genitalia for each species are provided, with a newly recorded species in Korea.

Currently, 12 subspecies of Coptolabrus smaragdinus have been recorded in Korea, of which 7 subspecies are listed in South Korea. C. smaragdinus has limited movement due to degenerated hindwings, resulting in high intraspecific diversity due to geographic isolation. Previous studies have been mainly classified based on external characters or genitalia structure, but the differences between subspecies are very ambiguous. In this study, we aimed to more clearly distinguish at the subspecific classification level, by examining the male aedeagal and inflated endophallus. Additionally, we provide photos of adult, endophallus and the process of endophallus inflation.

The genus Bembidion is a prominent terrestrial group found in various regions around the world, encompassing a large number of species. Species of this genus have a reduced apical palpomere, as do all members of the tribe Bembidiini. This study reviews four species belonging to the subgenus Plataphus, which is included within the genus Bembidion. Descriptions and photos of adults are provided.

The continuous use of pesticides with the same mode of action has lead to the development of insecticide resistance in the target pests. Establishing pesticide resistance management methods and effective control strategies for these pests has become an important target. Bemisia tabaci, a representative pest of greenhouse, directly affects the growth of crops at all stages of its development except eggs. It also causes indirect damage by secreting honeydew that eventually promotes sooty mold in leaves and fruits. In this study, eight insecticides with different mechanisms of action (Flonicamid, Fluxametamide, Spinetoram, Cyantraniliprole, Dinotefuran, Pyridaben, Milbemectin and Pyriproxyfen), and registered for use against cucumber B. tabaci were selected and tested for insecticide resistance. The tested populations of B. tabaci were collected from greenhouse cucumber cultivations in 12 domestic regions. The results were presented as RR (Resistance ratios), and CEI (Control efficacy index) values.

The rate of resistant pest emergence has accelerated due to the continuous use of pesticides. Therefore, it is important to formulate insecticide resistance management measures and effective control methods for pest. Bemisia tabaci, a greenhouse pest, causes direct damage to crops such as growth inhibition and leaf discoloration at all developmental stages except for eggs. It also indirectly damages plants by secreting honeydew, which covers surrounding leaves and fruits, leading to sooty mold development. In this study, eight insecticides with high usage rates, categorized by their mode of action, were selected. Samples of Bemisia tabaci were collected from six regions, and resistance analysis were conducted. The results showed that Flonicamid exhibited a resistance ratio of 8.91 in Sejong, while Pyriproxyfen showed a high resistance ratio of 63.56 in Gunwi. Fluxametamide, Spinetoram, Cyantraniliprole, Dinotefuran, Pyridaben, and Milbemectin displayed resistance ratio ranging from 0.02 to 1.14 in most regions, except for Flonicamid and Pyriproxyfen.

Pyroprocessing is a promising technology for managing spent nuclear fuel. The nuclear material accounting of feed material is a challenging issue in safeguarding pyroprocessing facilities. The input material in pyroprocessing is in a solid-state, unlike the solution state in an input accountability tank used in conventional wet-type reprocessing. To reduce the uncertainty of the input material accounting, a double-stage homogenization process is proposed in considering the process throughput, remote controllability, and remote maintenance of an engineering-scale pyroprocessing facility. This study tests two types of mixing equipment in the proposed double-stage homogenization process using surrogate materials. The expected heterogeneity and accounting uncertainty of Pu are calculated based on the surrogate test results. The heterogeneity of Pu was 0.584% obtained from Pressurized Water Reactor (PWR) spent fuel of 59 WGd/tU when the relative standard deviation of the mass ratio, tested from the surrogate powder, is 1%. The uncertainty of the Pu accounting can be lower than 1% when the uncertainty of the spent fuel mass charged into the first mixers is 2%, and the uncertainty of the first sampling mass is 5%.

농촌진흥청 국립원예특작과학원에서는 2017년에 절화 수명이 길고 수량이 많은 연한 핑크색의 스프레이 장미 ‘Pink Shine’ 을 육성하였다. 모본은 ‘Fire Flash’로 붉은 복색의 스프레이 장미이며, 부본은 ‘Pink Charm’으로 핑크색이며 흰가루병에 강하다. 이 두 품종을 2012년 인공교배하여 이듬해인 2013년 1월에 파종, 9cm 포트 묘에 정식하여 관능 평가 실시 후 도태시켜 39개체 의 실생을 얻었다. 이후 화형, 화색, 꽃잎 수, 절화수량, 병 저항성 등을 고려하여 2015년까지 5개체를 선발하여 유사 품종인 ‘Missha’를 대조로 하여 2017년까지 3차에 걸친 특성 검정을 실시하였다. 그 결과 가장 우수한 ‘원교 D1-325’를 최종선발하여 ‘Pink Shine’으로 명명 후 2018년 3월 22일 품종보호출원(제 2018-212호)하여 2019년 6월 21일에 품종보호권(제7786호)이 등록되었다. 화색은 연한 핑크색(RHS, R36D)이며 잎의 색은 녹색(RHS, G137A)으로 대조 품종 ‘Missha’와 동일하였다. 꽃잎 수는 67.8개, 화폭 5.4cm, 화고 3.2cm로 ‘Missha’보다 컸으며 평방미터당 연간 절화수량은 131본, 절화수명은 15.3일로 ‘Missha’ 보다 우수하였다.
