The structure of frontal thunderstorm in winter time is different from that of in summer time over the Korean peninsula, due to dry tongue and upward motion. The dry tongue, that is propagation of dry zone from upper level to lower level, was formed after front passage and the upward motion is intensified by the strengthened low level jet. Since this mechanism makes the structure more unstable, thunderstorm occurs at relatively low cloud top height. This study suggests a forecast guidance of winter time frontal thunderstorm that thunderstorms develop when one of the following conditions are satisfied: 1) total totals (TT) >40, 2) K index >-10, 3) mixing ratio ${\geq}$ 3.5 g/kg.

Hydnum is a genus of ectomycorrhizal fungi belonging to the Hydnaceae family. It is widely distributed across different regions of the world, including North America, Europe, and Asia; however, some of them showed disjunct distributions. In recent years, with the integration of molecular techniques, the taxonomy and classification of Hydnum have undergone several revisions and advancements. However, these changes have not yet been applied in the Republic of Korea. In this study, we conducted an integrated analysis combining the morphological and molecular analyses of 30 specimens collected over a period of approximately 10 years in the Republic of Korea. For molecular analysis, the sequence data of the internal transcribed spacer (ITS) region, the large subunit of nuclear ribosomal RNA gene (nrLSU), and a portion of translation elongation factor 1-a (TEF1) were employed as molecular markers. Through this study, we identified eight species that had previously not been reported to occur in the Republic of Korea, including one new species, Hydnum paucispinum. A taxonomic key and detailed descriptions of the eight Hydnum species are provided in this study.

The responsibility to ensure the health rights of detainees, particularly their medical rights, fundamentally lies with the state in all nations. However, in the correctional facilities of the Republic of Korea, these rights are currently not adequately safeguarded. Numerous detainees express dissatisfaction with the medical services provided and show a preference for voluntary external treatment. However, barriers such as prolonged application processes for external treatment and the requirement for detainees to cover their medical expenses present significant challenges. Therefore, the National Human Rights Commission of Korea has advocated for an increased medical budget in correctional facilities and a bolstered professional medical workforce to improve the medical care of detainees. Recommendations for improvements include: (1) establishing dedicated correctional hospitals for detainees, (2) setting up specialized correctional wards, (3) collaborating with military hospitals, (4) launching mobile medical buses for diverse specialties, (5) enhancing collaboration with public and private medical institutions, (6) increasing compensation for partnering external medical institutions, (7) improving the working conditions of medical officers, (8) safeguarding the defense rights of medical staff, (9) improving the working conditions of public health doctors from the Ministry of Justice in correctional facilities, and (10) pre-assigning public health specialists and military doctors to correctional facilities. By implementing these measures, it is anticipated that the quality of medical services in the Republic of Korea's correctional facilities will improve, reducing the demand for external treatments among detainees and ensuring their health and medical rights are realistically upheld.

Salmonellosis caused by a number of serotypes of Salmonella is an infectious, acute or chronic, zoonotic disease and characterized by enteritis and diarrhea, septicemia in animal. In these studies we investigated the prevalent serotypes of Salmonella causing animal salmonellosis in Korea and the 71 strains of Salmonella spp. were isolated from materials such as mesenteric lymph nodes, fecal samples from slaughtered animal. With the identification test results, the most prevalent serotypes were, in order, S stanley 31 strains (43.7%), S typhimurium 19 strains (26.8%) and S montevideo 11 strains (15.5%), respectively. And we could establish the method for detection of antibodies to broad variety of Salmonella serotypes. Lipopolysaccharide(LPS) antigen extracted from Salmonella was more sensitive and specific than outer membrane protein antigen from that for detection of Salmonella antibody by using an indirect ELISA. The optimal concentration of antigen was 100ng/ml of LPS, the dilutions of conjugate and serum were 1 : 1,000~2,000 and 1 : 200~400, respectively. The mix LPS-ELISA which was used by mixing LPS from S typhimurium (group B), S choleraesuis (group C) and S enteritidis (group D) were more rapid and effective than that used LPS from individual strain for detection of Salmonella serogroup O4, O7 and O9 antibody at the same time. We could obtain the high values of optical density ($0.73{\pm}0.32$) by mix LPS-ELISA on the farm which had occurred salmonellosis, but very low values of $0.17{\pm}0.06$ on the negative farm of salmonellosis. So, the mix LPS-ELISA may be used to monitor the serological surveillance for the presence of infection with a number of serotypes of Salmonella and would be useful for prevention and control of salmonellosis in animal.

본 논문에서는 해상상태 환경에 따른 카메라 센서 인식의 오차를 제어하고 보정 하기 위해 칼만 필터를 적용한 방법을 제시한다. 먼저, 함정의 제원을 기술하여 롤링에 따른 오차 정도를 측정하였다. 모델로 선택한 함정인 PKMR-211을 통해 시뮬레이션에 필요한 수면으로부터 현등까지 거리를 제시한 후, 피드백 제어 시스템에서 카메라 오차값을 변수로 삼아 오차 보정을 수행하였다. 실험에서는 함정의 롤링 정도를 각도로 나타내는 변수인 𝛼, 𝛽로 표기하고, 거리에 따른 각도 변화를 비교하였다. 해상 상태 3의 상황에서 칼만 필터를 적용하기 전과 후의 오차를 비교했을 때, 거리와 무관하게 적색등에서는 +1.5556°에서 -1.1544°까지 줄어들었고, 녹색등에서도 동일한 결과를 확인하였다. 이를 통해, 해상 환경에 따른 함정의 움직임을 고려하여 계산을 수행하고, 오차 보정 이후 함정의 향후 기동 안정성을 제시하였다.

Because of the potential negative influence on their hosts, ecto-parasites are of prime importance to numerous species. Ticks are among these, distributed worldwide, and potentially transmitting diseases while sucking blood of diverse hosts. The leopard cat (Prionailurus bengalensis euptilura Elliot, 1871) is the only felid left in the Republic of Korea following widespread anthropogenic disturbances that have resulted in the extinction of both Panthera species: the Siberian tiger(Panthera tigris altaica Temminck, 1844) and Amur leopard (P. pardus orientalis(Schlegel, 1857)). This study identifies ticks collected from a roadkill leopard cat retrieved in Seosan area in the Republic of Korea. Two ticks attached to the facial area of the carcass were identified as Japanese hard ticks, Ixodes nipponensis, based on mitochondrial cytochrome oxidase I. The matching sample was from Japan with 99.7% similarities, and the only available sequence on GenBank. This study reconfirms that I. nipponensis parasitizes the endangered leopard cat P. bengalensis euptilura.

전술 표적에 대한 정보를 획득하기 위해 전투기에 탑재하는 EO/IR 정찰용 파드는 일반적으로 항공기 동체 하단에 장착 운영한다. 이러한 외부 장착물을 장착한 항공기는 외부 장착물 없이 비행하는 항공기에 비하여 복잡한 공력 및 관성력 특성을 갖기 때문에 개발 초기에 개발 위험요소를 사전에 식별하여 설계에 반영할 수 있는 시스템 성능 분석 도구가 필수적으로 필요하다. 본 연구에서는 고기동 환경에서 안정적으로 측정 데이터를 획득할 수 있는 파드를 개발하기 위해 필요한 모델링 및 시뮬레이션 도구 개발 방안을 제시하였다. 우선, 고기동 항공기에 탑재한 파드의 한계 운용조건을 도출하고, 한계 운용조건에 따른 탑재 파드의 공력 및 관성 하중을 분석하였으며, 탑재파드를 장착한 항공기의 임무 모사를 통한 비행데이터 생성 및 전송 시스템을 개발하였다.
