There have been many researches about the driving mechanism for off-road mobility and the various utilities of rescue robot constantly. In this paper, a new type of driving mechanism for rescue robot which has a variable geometry single-track is introduced to achieve such objectives as surveillance, reconnaissance and rescue activity. It was designed to improve the performance of overcoming stairs and energy efficiency and to minimize its weight and size. We analyzed the design parameters for several steps of climbing stairs and confirm the possibility of realization of presented driving mechanism from various experiments.

N/A Background : Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown etiology. The disease is relatively common in western countries, but so far, only about 20 cases have been reported in Korea. Thus, the purpose of our prospective study was to evaluate the clinical characteristics of PBC in Korea. Methods : Between October 1994 and February 1999, 16 patients diagnosed as PBC at our department were enrolled in this study. We analyzed these patients for the distribution of age and sex, initial symptoms and signs, associated disorders, laboratory, endoscopic, and radiologic and histologic findings. Results : Of the 16 patients, the ratio of male to female was 1:7 and the average age was 57.5 years. Pruritus (37.5%) was the most frequent presenting symptom followed by xerostomia and xerophthalmia (12.5%), jaundice (6.3%), chronic fatigue (6.3%), melena (6.3%). Associated disorders were Sj gren's syndrome (25%), arthropathy (12.5%), Raynaud's phenomenon (6.3%) and diabetes (6.3%). Abnormalities of liver function were found frequently. Antimitochondrial antibody (100%), antinuclear antibody (31.25%) and rheumatoid factor (31.25%) were found. Long-term administration of UDCA improved both clinical and biochemical signs in most patients, however, 2 patients experienced exacerbation during UDCA therapy. Conclusions : We experienced 16 cases of PBC within a short period. It is expected that we can find these patients more frequently if we suspect this disease in patients with pruritus and unexplained obstructive pattern of liver function abnormality.(Korean. J. Med 59:634-640, 2000)
19세기 남명학파의 동향 일고찰 -월촌(月村) 하달홍(河達弘)의 삶과 교유활동을 중심으로-
박동일 ( Dong Il Park ) 경상대학교 남명학연구소 2014 남명학연구 Vol.44 No.-
月村 河達弘은 19세기 강우지역에서 활동했던 학자이다. 그는 실용 을 중시하는 학문경향을 가지고 南冥 曺植과 謙齋 河弘度를 존숭하며 慕寒齋에서 강학활동을 전개하였다. 이로써 인근의 학자들을 운집시키 고 그들에게 남명학파로서의 의식을 고취시켰다. 이때 月皐 趙性家ㆍ 溪南 崔琡民ㆍ東寮 河載文ㆍ克齋 河憲鎭ㆍ斗山 姜柄周ㆍ尼谷 河應魯 등이 그의 문하에서 종유하였다. 이후 조성가와 최숙민은 하달홍의 인도 아래 보다 체계적인 학문을 위해 노사학단에 나아가 奇正鎭에게 수학하였다. 한편 하재문과 하헌 진은 본거지로 돌아가 寒州 李震相과 교유하였고, 강병주와 하응로는 性齋 許傳에게 나아가 집지하였다. 조성가와 최숙민이 노사학단의 핵심인물로 자리매김한 것에 비해 하재문이 한주학단에서나 강병주가 성재학단에서 차지하는 비중은 그 리 크지 않다. 그러나 이들 모두는 남명을 존숭하고 학문의 실천성을중시하는 남명학파로서의 정체성을 가지고 있었다. 이를 통해 두 가지 사실을 알 수 있는데, 하나는 하달홍의 모한재 강학이 남명학파의 정체성을 확립하는데 큰 역할을 했다는 것과, 다른 하나는 하달홍이 노사학파와 친밀성이 깊다는 점이다. 다시 말해 하달홍은 19세기 하동과 인근 강우지역의 문인들에게 남 명의 학문과 사상을 계승하고 보다 큰 학문을 접할 수 있도록 발판의 역할을 해 주었으며, 이를 통해 그 문인들은 남명학파로서의 정체성을 가지고 각자의 학문을 발전시켜 나갔던 것이다. Ha Dal-hong(河達弘, 1809~1877) was a scholar who worked in the Rainfall Area. He respected Nammyeong(南冥) Jo-Sik(曺植)ㆍ Kyumjae(謙齋) Ha Hongdo(河弘度) besides had a practical academic tendency. And gatherd the young scholars around as inspired the Nam-myoung school``s consciousness. Especially scholars such as Wolko(月皐) Cho Sung-ga(趙性家), Gyenam(溪南) Choi Suk-Min(崔琡民) gatherd there When he was studying at Ha Hongdo``s school Mohanjae(慕寒齋). Since then, Cho Sung-ga and Choi Suk-Min enterd the Nosa School of Ki Jung-jin(奇正鎭) for systematic studying under his leadership. Other scholars enterd the Han-ju School of Yi jin-sang or Sung Jae School of Heo Jeon. Even though they said they had a different academic orientation emphasized the practical academic tendency. And they had a identity as Nam-myoung school``s scholar. So Ha Dal-hong had a great influence in that Rainfall Area``s people had a identity as Nam-myoung school``s scholar, Through this, he receives a rating that succeed to the Ha Hongdo``s learning.

Extrapancreatic fluid collection is well known comp1ication of pancreatitis. Involvernent of the left perirenal space is extremely rare and it is often difficult to differentiate from the cystic disease of renal and ureteral origin. We present 1 case of pancreatic pseudocyst which is located at the left perirenal space. We did distal pancreatectomy with splenectomy to disconnect the communicating duct frorn the cyst and the huge cyst was drained externally.
