This study aimed at looking into Kang Hui-maeing's office life for the understanding of the early Joseon society dominated by yangban(two upper classes). Through reviewing on his life we can interpret constant factors to make his way in office life in Joseon as well as variable ones. He was out of top drawer, a nephew of King Sejong's wife and got the first position in the civil service examination come up 1447, King Sejong's 29th year. He enjoyed a success career during King Sejo's ruling period(1455~1468) and reached the peak point when King Seongjong rose. He started office life in 24 years old and got a dangsanggwan position, the major third rank, 10 years later. He took office as the minister of the Ceremonies Board in 1466, King Sejo's 12th ruling year. He died at 1483 with two titles as a meritorious retainers without taking the position for state councilor. Key point of his success was to have taken good results, ranked the first class, in the successive two tests by King Sejo for inservice officers. This enabled hime to get dangsoangwan and panseo post. He was a ceremony and writing expert whom the dynasty need for establishing confucian state and keeping stable relations with Ming China. He went through almost all posts in the Ceremonies Board from jwarang(assistant section chief) to panseo (Minister). He had his son got to married to a grand daughter of Sin Sukju, first class meritorious retainer. It helped him to get the meritorious title. He participated in discussion sessions with the king Seong Jong as a Gyeongyeongwan holding additional posts and meritorious retainer. Seongjong left his first son who acceded to the throne later in Kang's care for several years and nominated him for Yijo-panseo positon, Minister of Personnel. His success story shows that in Joseon society a person could not success depending solely on one's family. For successful office life it requires to be a fine writer and to get a special status like a meritorious title.

어린 오리에 치명적인 질병을 일으키는 오리바이러스성간염의 예방을 위해 혼합생백신 개발, 백신의 방어기전 연구 및 종오리백신 프로그램의 개발로 질병방어 및 제어를 목표로 연구를 진행하였다. 첫 번째, 국내에는 1형과 3형이 동시 유행하고 있으며, 최근에는 3형의 발생보고가 증가하는 추세이다. 특히 1형과 3형의 복합감염사례도 빈번히 발생하고 있다. 이런 상황에서 효율적인 질병관리를 위해 국내에 발생하는 오리간염 1형과 3형을 동시에 방어하는 혼합백신을 개발하고 그 효능을 확인하였으며, 운반 및 보관 용이성 향상을 위한 연구를 진행하였다. 두 번째, 오리감염 생백신의 3-5일 만에 조기면역을 획득하는 특성분석을 위해 세포성 및 체액성 면역반응을 평가하였다. Cytokine이 백신접종 그룹에서 증가하는 것을 확인하였고, 특히 IFN-α에서 강한 증가를 보였다. 또한 항체가 평가에서는 기존에 알려진 바와는 다르게 백신 후 3일째에 항체를 획득하였고, 10일째에는 최고수준의 항체가 수준을 나타냈다. 세 번째, 1주령이하의 어린 일령에 치명적인 질병의 특성상 모체이행항체에 의한 예방이 가장 효과적이라는 점에 착안하여 종오리백신 프로그램을 개발하고 농장에 적용하여 평가하였다. 종오리 농장 4개동 4천수의 종오리를 대상으로 백신을 실시하였으며, 모체의중화항체가(VN titer) 8 log2이상에서 후대병아리 14일령까지 100% 방어효능을 확인하였다. 모체이행항체의 전달률은 11%수준으로 나타났으며, 후대병아리의 항체가를 개체별 추적하여 계산한 결과 모체이행항체 반감기는 3-5일령임을 확인하였다. 본 연구에서는 오리에 치명적인 질병을 일으키는 오리바이러스성간염 예방을 위한 혼합생백신 개발에 관한 연구로 기존의 국내 상용화백신의 한계점을 극복하고, 국내에 유행하는 혈청형들을 단회백신으로 효과적으로 방어할 수 있는 혼합생백신을 개발하였으며, 백신의 특성상 조기면역에 대한 세포성 및 체액성 면역기전을 평가하였다. 또한 종오리백신 프로그램을 국내에 적용하여 모체이행항체에 의한 후대 병아리의 우수한 방어 효능을 확인하였다.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.
Comparative AFLP Profiles among Strains of Korean Races of Xanthomonas oryzae pv. oryzae.
Kang,Mi-Hyung,Lee,Du-Ku,Noh,Tae-Hwan,Shim,Hyeong-Kwon,Na,Seung-Yong,Kim,Jae-Duk 한국자원식물학회 2004 Plant Resources Vol.7 No.1
We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.
Hydrogen Behavior in Ti-Added Reduced Activation Ferritic-Martensitic Steels

Hydrogen behavior and corresponding mechanical degradation were examined in TaTi-RAFM and EUROFER97 steels. Increased Ta content with Ti addition decelerates the hydrogen diffusion but increases the solubility in the lattice. It ismainly led by the higher fraction of Ta-rich MC carbides and dislocation density in TaTi-RAFM steel. Overall activationenergy of hydrogen trapping of investigated steels is evaluated to be 25.3 ~ 25.6 kJ/mol in the tempered condition. The activationenergy increases to nearly 30 kJ/mol when the steels are re-austenitized and quenched. Higher activation energy withincreased dislocation density indicates that the dislocation provides for trap site with higher activation energy than Ta-richMC carbide. Mechanical degradation by hydrogen with respect to the yield strength, tensile strength and uniform elongationcould not be observed in all investigated steels. The presence of hydrogen only has influence on the loss of post-uniformelongation. For a given charging time, the loss of post-uniform elongation is more remarkable in TaTi-RAFM steel due tothe larger hydrogen uptake.
