Production of Monoclonal Antibodies Against the Immunoglobulin M of Olive Flounder Paralichthys Olivaceus

Korean Journal of Fisheries and Aquatic Sciences (2017)

Wi‐Sik Kim Ki-Hong Kim Choon-sup Kim Myung‐Joo Oh

Immunoglobulin M (IgM) was purified from olive flounder Paralichthys olivaceus sera using mannan-binding protein (MBP) and protein L affinity columns (designated as MBPIgM and ProLIgM, respectively). A monoclonal antibody (MAb) against olive flounder IgM was produced. The MBPIgM and ProLIgM had apparent molecular weights of 77, 73, and 28 kDa in SDS-PAGE. Nine hybridomas secreting MAbs against olive flounder IgM were established: five MAbs for MBPIgM (1, 2, 3, 4, and 5) and four for ProLIgM (6, 7, 8, and 9). Western blotting indicated that seven MAbs recognized heavy (H; MAbs 1, 2, 3, 4, 5, 6, and 7) chains and one recognized light (L; MAb 9) chains of IgM, while MAb 8 did not recognize IgM. The results of enzyme-linked immunosorbent assay (ELISA) with bovine serum albumin (BSA, antigen) and the nine MAbs revealed that the optical density (OD) values of sera differed significantly between BSA- and non-immunized fish, despite some sera from non-immunized fish with slight high OD values. These results suggest that the MAbs produced in this study reacted specifically with the IgM from olive flounder.

A mechanism for end-to-end secure communication in heterogeneous tactical networks

Journal of the Korea Institute of Information Security and Cryptology (2014)

Cheolyong Park Ki-Hong Kim Jae‐Cheol Ryou

전술통신망은 이기종 다양한 특성의 통신장비로 구성된 네트워크가 복합적으로 운용되고 있다. 이러한 구성으로 인해 종단간 통신을 위해 기종별 데이터 포맷으로 변환하기 위한 망연동 게이트웨이를 적용하고 통신 정보보호를 위해 네트워크별 암호기술이 적용되고 있다. 이는 이기종 망간 암호화된 데이터를 직접 전송할 수 없고 통신데이터의 재가공 및 처리지연의 문제점이 있다. 서로 다른 전술통신망 사이에 위치하는 망연동 게이트웨이에서 통신데이터에 대한 재가공과 암호화 데이터에 대한 복호화 및 재암호화가 요구된다. 본 논문에서는 전술통신망에서 이기종간 종단간 암호화 통신을 위한 통신방식을 제안한다. 제안한 방식을 이용하여 PSTN과 UHF 통신망간 게이트웨이에서 재가공, 재암호화, 전송 지연요소 등을 없애 실시간 음성 및 데이터 통신을 가능하게 한다. 또한, 종단간 정보보호를 위해 단대단 정보보호방식을 적용한다. 이를 통신망에 적용하여 기존 방식 대비 제안한 방식의 성능을 비교 분석한다. 제안한 방식은 기존방식의 문제점을 해결하고 이기종 전술통신망간 종단간 암호화 통신이 가능함을 확인하였다. Tactical networks is being operated in configuration that consisting of a variety of characteristics communication equipments and heterogeneous networks. In this configurations, end-to-end communication can be achieved using interworking gateway for converting the data format of the network and using encryption algorithm of the networks. The use of mechanism results in a problem that secure data cannot be transferred directly, reprocessing and processing delay of communication in heterogeneous tactical networks. That is, for encoding and decoding of data, the decryption of encrypted data and re-encryption processing must be required at the gateway between different networks. In this paper proposes to mechanism for end-to-end secure communication in heterogeneous tactical networks. Using the proposed method, end-to-end secure communication between heterogeneous tactical networks(PSTN-UHF networks) which removes the necessity of a gateway for converting data into data formats suitable for network to remove a transmission delay factor and enable real-time voice and data communication and achieve end-to-end security for heterogeneous tactical networks. we propose a novel mechanism for end-to-end secure communication over PSTN and UHF networks and evaluate against the performance of conventional mechanism. Our proposal is confirmed removal of security vulnerabilities, end-to-end secure communication in heterogeneous tactical networks.

Jun Sik Lee Ki-Hong Kim Hyung Jong Kim

본 연구에서는 광학적 방법으로 곡면변형률을 측정하고자 할 때, 소재 표면이 임의의 곡면이거나 요철이 많은 경우, 부식이나 오염으로 표면이 불량한 경우, 그리고 고무나 폼, 생체 조직 등과 같이 규칙적인 격자망을 인쇄하기 어려운 경우에도 적용할 수 있는 자동 곡면변형률 측정시스템 ‘ASIAS-bio’를 개발하였다. 이 시스템은 시편의 재질과 표면상태, 격자 패턴과 크기, 격자 마킹 방법, 변형 정도 등 측정 조건에 관계없이 사용이 가능한 것이 특징이다. 우선 그 신뢰성을 평가하기 위하여 금속판재 성형제품의 변형률 분포를 상용 장비로 측정한 결과와 비교하였다. 또한, 돼지 어깨 관절막, 인체 무릎 피부 등 연질 생체 조직의 변형 측정에 적용함으로써 본 시스템의 유용성을 확인하였다.

Fermented whey protein supplementation improves muscular strength, muscle parameters, and physical performance in middle-aged Korean adults: An 8-week double blind randomized controlled trial

Food Science of Animal Resources (2023)

Cheol‐Hyun Kim Yu-Bin Jeon Dong-Gyu Yoo Ki-Hong Kim Hwan-Jong Jeong

The present study evaluated the effects of fermented whey protein using kimchi lactic acid bacteria Lactobacillus casei DK211 on skeletal muscle mass, muscle strength, and physical performance in healthy middle-aged males performing regular resistance exercises. Effective protein supplementation and regular exercise are two important factors for improving muscle health. Therefore, in this study, the effects of consuming fermented whey protein twice a day were investigated and compared with that of non-fermented supplementation. Forty-eight males (average age 44.8) were randomly assigned to two groups: Fermented whey protein supplementation (FWPS) and non-fermented whey protein concentration supplementation (WPCS) groups. Each group ingested 37 g of FWPS or WPCS twice a day for eight weeks. Body composition, muscle strength, and physical performance were assessed pre- and post-intervention. Independent t-tests or chi-square tests for the categorical variables were performed for analyzing the observations. FWPS was effective in promoting the physical performance in dynamic balance measurement and muscle health, indicated through the increment in grip strength (left), upper arm circumference, and flat leg circumference from the baseline. However, similar improvements were not observed in the WPCS group. These results imply that whey protein fermented by L. casei DK211 is an effective protein supplement for enhancing muscle health in males performing regular resistance exercises.

In Situ Photoelectron Spectroscopy Study on the Buffer Role of Multiwalled Carbon Nanotubes against Thermal Degradation in Organic Conducting Composite Films with PEDOT:PSS

The Journal of Physical Chemistry C (2019)

Dong‐Jin Yun Sung Hoon Park Jinyoung Hwang Hyemin Ra Jung‐Min Kim

To ensure stable operation during use, the fundamental characteristics of each component in devices must be maintained. Organic electrodes of poly(3,4-ethylenedioxythiophene) polymerized with poly(4-styrenesulfonate) (PEDOT:PSS) have many deficiencies in this regard despite being widely used in various fields. Here, on the basis of various analytical results, we clearly identify not only significant denaturation of PEDOT:PSS at high temperature but also stability improvement by doping with multiwalled carbon nanotubes. As the thermal annealing temperature increases, the ratio of C–S to S–Ox bonds in PEDOT:PSS films becomes higher, owing to chemical changes and decomposition of PEDOT:PSS molecules. Further, obvious decline in work function and electrical conductivity occurs. On the other hand, the MWNT chains in a MWNT/PEDOT:PSS composite form conductive charge-carrier paths resembling a densely intertwined web. Thanks to its excellent thermal and electrical conductivity, the MWNT/PEDOT:PSS composite can serve as an electrode even after high-temperature annealing, despite denaturation of the PEDOT:PSS molecules.
