This study evaluated the immunogenicity of the Bacillus Calmette-Guérin (BCG) vaccine in a guinea pig model to refine preclinical assessment methods. 24 guinea pigs were divided into four groups for immunohistochemical, histopathological, and molecular analyses, including qRT-PCR and ELISA. The ELISA results revealed significant elevations in interleukin 2 (IL-2), interferon-gamma (IFN- ), and tuberculosis-specific antibodies in vaccinated guinea pigs, particularly γ notable after 6 weeks. Although lung cytokine levels remained unchanged, spleen gene expression showed significant differences in interleukin-17, interleukin-12, interleukin-1β, and C-X-C motif chemokine ligand 10 after 6 weeks. Immunohistochemistry revealed peak IL-2 expression at 8 weeks and significant IFN-γ and TNF-α expression at 6 weeks. This study confirmed the effectiveness of BCG vaccine in guinea pigs, providing crucial insights for future tuberculosis vaccine development and standardizing immune response indicators.

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.

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.

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 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.

Polymeric carbon nitride (p-C3N4) is a promising platform as a metal-free photo-catalyst for various reactions. The p-C3N4 can be produced by thermal poly-condensation of organic precursors. Their morphological and chemical structures depend on reaction conditions during the poly-condensation. In this study, two p-C3N4 materials are produced by heat treatment of urea under different gaseous conditions with air (urea-derived carbon nitride under air, UCN-A) and N2 (UCN-N), respectively. UCN-A and UCN-N samples are mesoporous materials and show excellent photocatalytic activities for degrading rhodamine B, an organic pollutant, under the irradiation of visible light. The UCN-A shows the better photocatalytic activity than UCN-N. Various characterizations reveal that more porous structures and larger surface areas of UCN-A are reasons for the better photocatalytic performance.

본 논문에서는 외계 행성에서 주어진 임무를 모두 수행하여 클리어하는 탑 뷰 슈팅 게임을 제안한다. 제안 하는 게임을 진행한 플레이어 45명의 로그 기록과 설문 조사 결과를 분석하여, 몰입감, 플레이 패턴의 다양 성, 접근성을 중심으로 제안하는 게임의 특징을 살펴보고자 한다. 첫째, 제안한 게임은 더 높은 몰입감을 위 해 스토리 애니메이션과 오디오를 제공한다. 실험 결과 시각, 청각적 방면으로 몰입감을 효과적으로 제공하 고 있어 대다수의 플레이어가 스토리 애니메이션을 건너뛰지 않고 끝까지 시청했다. 둘째, 제안하는 게임은 더 다양한 플레이 패턴으로 즐길 수 있다. 실험 결과 수많은 경우의 수가 존재하는 무기와 스킬을 선택할 수 있게 하였기 때문에 대부분의 플레이어가 선택하는 스킬들이 서로 겹치지 않고 다양한 방식으로 게임을 플레이할 수 있다. 플레이 패턴이 다양한 만큼 더 게임을 오랫동안, 더 재미있게 즐길 수 있다. 셋째, 제안한 게임은 맵을 비교적 단순하게 구성하였다. 그런데, 호기심 많은 일부 플레이어들이 미션과 직접 관련이 없는 경로를 찾아서 길을 헤매는 경우가 나타났다. 이로 인해, 플레이어들이 게임을 다시 한번 진행하고자 하는 경향이 나타났다.
